Description

Dust collector, control method for the same, control program, and recording medium storing program

The present invention relates to a dust collector that generates a dust collection airflow in a room and collects dust using the dust collection airflow.

A conventional dust collector has, for example, a blower inside the dust collector and an exhaust port opened above the dust collector. This dust collector is placed in the corner of the room. The exhaust air blown out from the exhaust port generates a dust collection airflow circulating in the room. The dust in the room is collected by a dust collection airflow (see, for example, Patent Document 1).

FIG. 24 shows a state in which the dust collector is installed indoors. In FIG. 24, the upper side shows the ceiling 106 and the lower side shows the floor surface 107. FIG. 24 shows a state in which the room in which the dust collector is installed is viewed from the side.

24, the dust collector 101 has a blower 102 inside. The dust collector 101 has an intake port 103 on the front surface and an exhaust port 104 on the top surface. The dust collector 101 is placed in the corner of the room 108. The air exhausted from the exhaust port 104 generates a dust collection airflow 105 that circulates in the room. The dust collection air flow 105 flows upward along the wall surface 109 and reaches the ceiling 106. The dust collection airflow 105 that has reached the ceiling 106 flows along the ceiling 106. Further, the dust collection air flow 105 is caused to flow along the wall surface 110 facing the dust collection device 101. Thereafter, the dust collection air flow 105 reaching the floor surface 107 is caused to flow along the floor surface 107. The dust collecting air flow 105 is sucked into the dust collecting apparatus 101 from the suction port 103. The dust collection air flow 105 collects dust existing in the room.

As shown in FIG. 25, another conventional dust collector is provided with a plurality of dust collectors 111A and 111B in the room. The dust collector 111A has a plurality of air inlets 113A and 113D and a plurality of air outlets 114A and 114D. The intake port 113A and the exhaust port 114A can be switched. The intake port 113D and the exhaust port 114D can be switched. The dust collector 111B has a plurality of intake ports 113B and 113C and a plurality of exhaust ports 114B and 114C. The intake port 113B and the exhaust port 114B can be switched. The intake port 113C and the exhaust port 114C can be switched. The dust collection performance is enhanced by operating the plurality of dust collection units 111A and 111B in synchronization (see, for example, Patent Document 2).

FIG. 25 shows a state in which a plurality of dust collecting portions 111A and 111B are installed indoors. In FIG. 25, the upper side shows the ceiling 106 and the lower side shows the floor surface 107. FIG. 25 illustrates a state in which the room in which the dust collector is installed is viewed from the side.

25, the dust collection units 111A and 111B have a blower 102 inside. The dust collectors 111 </ b> A and 111 </ b> B have a height from the floor surface 107 to the ceiling 106. The dust collection unit 111A has a pair of intake ports 113A and exhaust ports 114A near the ceiling 106, and another set of intake ports 113D and exhaust ports 114D near the floor surface 107. Similarly, the dust collection unit 111B has a pair of intake ports 113B and exhaust ports 114B near the ceiling 106, and another set of intake ports 113C and exhaust ports 114C near the floor surface 107.

The dust collecting portions 111A and 111B installed so as to face each other form a dust collecting air flow 105A by the following air flow. Air in the vicinity of the ceiling 106 is sucked from the air inlet 113B of the dust collecting unit 111B. This air is exhausted from the exhaust port 114C to the vicinity of the floor surface 107. The air exhausted along the floor surface 107 is sucked into the dust collector 111A from the air inlet 113D. The sucked air is exhausted from the exhaust port 114A to the vicinity of the ceiling 106. This circulating air flow becomes the dust collection air flow 105A. In the dust collection air flow 105A, not only the exhaust from the exhaust port 114C but also the intake port 113D takes in air, whereby a strong air flow is formed in the vicinity of the floor surface 107. The dust collectors 111A and 111B allow the dust collection air flow 105B indicated by the broken line arrow to enter the room 108 by switching the intake ports 113B and 113D and the exhaust ports 114A and 114C to the exhaust ports 114B and 114D and the intake ports 113A and 113C. It is formed. As a result, the dust hidden behind the furniture and the like and not collected by the dust collection airflow 105A is collected by the dust collection airflow 105B in the reverse direction.

However, in the conventional dust collector, the dust collecting airflows 105, 105A, and 105B are forcibly sucked and exhausted only by the blower 102 provided inside the dust collecting device 101 and the dust collecting portions 111A and 111B. Therefore, a strong air flow is generated in the vicinity of the exhaust ports 104 and 114A to 114D and the intake ports 103 and 113A to 113D, but the air flow in the vicinity of the ceiling 106 and the floor surface 107 or the wall surface 110 facing the dust collector 101 is weakened. . Therefore, in order to collect the dust existing in the room, it is necessary to form a strong airflow over the entire room.

Embodiments of the present invention will be described with reference to the drawings. The following description shows a specific example of the present invention. However, the contents of the present invention are not limited.

(Embodiment 1)
FIG. 1 is a perspective view of a room provided with the dust collector in Embodiment 1 of the present invention.

As shown in the figure, the dust collector according to the first embodiment of the present invention includes a blower 7A that is a first blower, a dust collector 8, and a controller 9 that is a first controller. .

Blower 7A blows out airflow 1 as the first airflow into the room. The dust collection unit 8 sucks indoor air. The dust collecting unit 8 removes the dust 2 that is the first dust contained in the air. The dust collecting unit 8 blows out the air from which the dust 2 has been removed into the room as an air flow 3 that is a second air flow. The control unit 9 controls the blower 7 </ b> A and the dust collection unit 8. The controller 9 combines the airflow 1 and the airflow 3 to form a dust collection airflow 10.

Furthermore, the dust collector includes a blower 7B which is a second blower. The control unit 9 also controls the blower 7B. The controller 9 synthesizes the airflow 1 and the airflow 3 as well as the airflow 4 that is the third airflow to form a dust collection airflow 10.

The dust collection airflow 10 is an airflow circulating in the room. The dust collection airflow 10 is an airflow directed toward the dust collection unit 8. Hereinafter, it will be described in detail with reference to the drawings.

The room 5 shown in FIG. 1 has a floor surface 6, wall surfaces 50 and 53, and a ceiling 17. Blowers 7A and 7B are provided in the room 5. The blower 7 </ b> A is provided in the vicinity of the ceiling 17 above the wall surface 50. The blower 7 </ b> B is provided near the ceiling 17 above the wall surface 53. The dust collecting unit 8 is provided in the vicinity of the wall surface 53 on the floor surface 6. The dust detection unit 81 is attached inside the dust collection unit 8. The control unit 9 is configured integrally with the dust collection unit 8. The control unit 9 controls the blowers 7 </ b> A and 7 </ b> B and the dust collection unit 8 based on the detection result of the dust detection unit 81.

Each part will be described with reference to the block diagram shown in FIG. The dust collecting unit 8 includes an intake guide 85, a blower fan 83, and an exhaust guide 86 as a wind circuit. The intake guide 85 has a dust collection filter 84. The exhaust guide 86 has a louver 87 as a direction control unit. The intake guide 85 sucks the dust collection airflow 10 by the operation of the blower fan 83. The dust 2 is sucked into the intake guide 85 together with the air sucked as the dust collection airflow 10. The dust collection filter 84 removes the dust 2. The blower fan 83 blows out the air from which the dust 2 has been removed from the exhaust guide 86 as the air flow 3. The louver 87 changes the blowing direction of the airflow 3.

In the present embodiment, as described above, since the control unit 9 is configured integrally with the dust collection unit 8, the control unit 9 has two functions. One is a function for controlling the entire dust collecting device, and the other is a function for controlling the air volume and the wind direction of the dust collecting unit 8.

The function that the control unit 9 controls the entire dust collector will be described.

The dust detector 81 provided in the dust collector 8 detects the dust 2 in the room. Specifically, the dust detection unit 81 uses a particle counter or the like. The particle counter emits laser light. The irradiated laser light is scattered when it hits the dust 2 or the like. By measuring the level of scattered light, the amount of dust 2 and the like in the air can be detected. Particle counters are used in clean rooms.

Based on the detection result of the dust detection unit 81, the control unit 9 controls the blowers 7 </ b> A and 7 </ b> B and the dust collection unit 8 to adjust the dust collection air flow 10. The control unit 9 transmits a control signal from the first communication unit 82 to the control unit 72A of the blower 7A via the second communication unit 71A. The control unit 9 transmits a control signal from the first communication unit 82 to the control unit 72B of the blower 7B via the third communication unit 71B. The control signal may be transmitted using infrared light or wireless communication such as radio waves. The control unit 9 and the dust collection unit 8 are integrally formed. The control unit 9 directly transmits a control signal to the blower fan 83 and the louver 87 included in the dust collection unit 8. In addition, the control part 9 and the dust collection part 8 may be separate bodies.

The blower 7A includes a second communication unit 71A, a control unit 72A, a blower fan 73A, and a louver 74A. Similarly, the blower 7B includes a third communication unit 71B, a control unit 72B, a blower fan 73B, and a louver 74B.

The blower 7A receives the control signal transmitted by the control unit 9 using the second communication unit 71A. The received control signal is transmitted to the control unit 72A. The controller 72A calculates the air volume and the air direction adjusted by the blower 7A. Based on the calculation result, the blower fan 73A and the louver 74A are controlled, and the airflow 1 is formed.

Similarly, the blower 7B receives the control signal transmitted by the control unit 9 using the third communication unit 71B. The received control signal is transmitted to the control unit 72B. The controller 72B calculates the air volume and the air direction adjusted by the blower 7B. Based on the calculation result, the blower fan 73B and the louver 74B are controlled, and the airflow 4 is formed.

On the other hand, the dust collecting unit 8 directly transmitted with the control signal from the control unit 9 to the blower fan 83 and the louver 87 forms the airflow 3 based on the transmitted control signal. These airflows 1, 4, and 3 are combined to form a dust collection airflow 10.

The operation and action of the dust collector configured as described above will be described below.

FIG. 3 is a vertical sectional view of a room provided with a dust collector according to the embodiment of the present invention. 4 to 9 are horizontal cross-sectional views of a room provided with a dust collector according to the embodiment of the present invention. FIG. 10 is an operation flow diagram of the dust collector according to the embodiment of the present invention.

First, the relationship between the dust collection airflow 10 and the blowers 7A and 7B will be described.

For the following explanation, symbols of α, β, γ, and δ are given to the four corners of the room 5 in the figure. Further, α1, β1, γ1, and δ1 are attached to the ceiling 17 side, and α2, β2, γ2, and δ2 are attached to the floor surface 6 side.

The dust collection airflow 10 formed by the dust collection unit 8 is the airflow shown in FIG. That is, the airflow 3 constituting the dust collection airflow 10 is blown out from the dust collection portion 8 along the wall surface 53 toward the ceiling 17. The airflow 3 that has reached the ceiling 17 flows in the direction of the wall surface 51 along the ceiling 17. The airflow 3 becomes the airflow 1 through the blower 7A. The airflow 1 that has reached the wall surface 51 flows in the direction of the floor surface 6 along the wall surface 51. The airflow 1 that has reached the floor surface 6 flows along the floor surface 6 to the dust collecting unit 8. As a result, the dust collection air flow 10 forms a flow circulating in the room.

Blowers 7A and 7B assist the dust collecting unit 8. The blowers 7A and 7B are provided in the room so that the dust collection airflow 10 is a flow that circulates throughout the room. As shown in FIG. 1, the blower 7 </ b> A is provided near the ceiling 17 of the wall surface 50. The blower 7A forms an airflow 1 that flows from β1 to γ1. The blower 7B forms an airflow 4 that flows from α1 to β1.

If the air volume and direction of the dust collecting unit 8 and the air volumes and directions of the fans 7A and 7B are adjusted, the flow of the dust collection air flow 10 circulating in the room can be changed. The control unit 9 switches the air volume and direction of the dust collecting unit 8 and the air volume and direction of the blowers 7A and 7B every predetermined time. As a result, the dust collection airflow 10 flows so as to circulate throughout the room. A specific example will be described with reference to Table 1 and FIGS.

The flow of the dust collection airflow 10A is formed by the pattern A of the operating conditions. The details are as follows. The air volume of the dust collecting unit 8 is large, and the wind direction is vertically upward (α2 to α1). The air volume of the blower 7A is small, and the wind direction is in the horizontal direction (β1 to γ1). The air volume of the blower 7B is small, and the wind direction is in the horizontal direction (α1 to β1). This flow is denoted by reference numeral 10 </ b> A in FIG. 4 showing a horizontal sectional view of the room 5.

The flow of the dust collection airflow 10B is formed by the pattern B of the operating conditions. The details are as follows. The air volume of the dust collecting unit 8 is large, and the wind direction is slightly leftward in the vertical direction in FIG. 5 (near the middle between α2 and α1 and β1). The air volume of the blower 7A is large, and the wind direction is in the horizontal direction (β1 to γ1). The air volume of the blower 7B is large, and the wind direction is in the horizontal direction (α1 to β1). This flow is denoted by reference numeral 10B in FIG.

FIGS. 6 to 9 show other installation examples of the blowers 7A and 7B. 6 and 7, two fans 7A (7AA, 7AB) and 7B (7BA, 7BB) are installed. The airflows 1A and 1B are adjusted using the blowers 7AA and 7AB. The airflows 4A and 4B are adjusted using the blowers 7BA and 7BB. The airflows 1A and 1B and the airflows 4A and 4B are adjusted to form dust collection airflows 10A and 10B. If the number of installed fans 7A and 7B is increased, the control unit 9 can adjust the dust collection airflows 10A and 10B that are finer and have a larger air volume. The number of fans 7A and 7B installed can be changed as appropriate based on the size of the room 5, the arrangement of furniture, and the like.

8 and 9, the blower 7A can form two directions (1A, 1B) of wind directions. If the number of installed fans 7A is reduced, the dust collection airflow 10 can be formed with simpler control.

As is clear from the above description, the control unit 9 controls the dust collection unit 8 and the fans 7A and 7B. By this control, a dust collection airflow 10 that circulates throughout the room is formed.

Next, an operation flow for forming the dust collection airflow 10 that circulates in the entire room shown in FIG. 10 will be described.

When the dust collector 8 of the dust collector is activated, the dust detector 81 starts detecting the dust 2 floating in the room (Step 1). When the dust 2 is detected by the dust detection unit 81, the control unit 9 calculates the dust collection airflow 10 required by the room 5. Based on this calculation result, the control unit 9 further calculates airflows 1, 4, and 3 that form the dust collection airflow 10. The control unit 9 transmits a control signal for realizing the calculated airflows 1 and 4 to the control units 72A and 72B. Based on the control signal, the blower fans 73A and 73B blow out the airflow 1 into the room (step 2). The control unit 9 directly controls the blower fan 83 and the louver 87 in order to realize the airflow 3. The control signal is transmitted from the control unit 9 to the control units 72A and 72B from the first communication unit 82 via the second communication units 71A and 71B. The dust collecting unit 8 sucks indoor air and removes dust 2 contained in the air. Based on the control signal, the dust collector 8 blows out the air from which the dust 2 has been removed into the room as an air flow 3 (step 2).

As a result, wind is blown out from each of the blower fans 73A, 73B, 83. Based on the control signal, the blown air flow 1 and the air flow 3 are combined to form a dust collection air flow 10 (step 2). Based on the control signal, the airflow 1 and the airflow 3 are adjusted so that a predetermined dust collection airflow 10 is formed (step 2).

After a predetermined time has elapsed (step 3), the control unit 9 changes the operating conditions (step 4). Further, after a predetermined time has elapsed (step 5), the control unit 9 detects the remaining state of the dust 2 in the room using the dust detection unit 81 (step 6). The predetermined time set in step 3 and step 5 may be about 1 minute. If the control unit 9 detects that the dust 2 is present in the room, the operation after step 2 is repeated.

On the other hand, if the control unit 9 cannot detect the presence of the dust 2 in the room, the air blowers 7A and 7B and the dust collecting unit 8 are stopped after a predetermined time (step 7) (step 8). The predetermined time set in step 7 may be about 2 minutes. Thereafter, the control unit 9 returns to the detection waiting operation for the dust 2 in the room.

As described above, in the first embodiment of the present invention, the control unit 9 uses the dust detection unit 81 provided in the dust collection unit 8 to detect the dust 2 floating in the room. Based on the detection result of the dust 2, the control unit 9 operates the dust collection unit 8 and the fans 7A and 7B in cooperation with each other. The dust collecting unit 8 forms the air flow 3, the blower 7 </ b> A forms the air flow 1, and the blower 7 </ b> B forms the air flow 4. The dust collection airflow 10 is formed by combining the airflows 3, 1, and 4. That is, the control part 9 forms the dust collection airflow 10 which circulates the whole room by switching the air volume and wind direction of the dust collection part 8 and air blowers 7A and 7B for every predetermined time. As a result, the dust 2 floating in the room can be efficiently removed.

In the first embodiment, the description has been given of the configuration in which the dust collector mainly includes one dust collecting unit 8 and two fans 7A and 7B. The configuration of the dust collector may be appropriately selected according to the size and shape of the room 5 as shown in FIGS.

The operating conditions of the dust collector were described using two patterns, pattern A and pattern B. A finer control pattern may be set as the operating condition for forming the dust collection airflow 10. Further, the operating condition may be formed so that the dust collection airflow 10 flowing in a specific direction is biased depending on the size, shape, and purpose of the room 5.

(Embodiment 2)
FIG. 11 is a perspective view of a room provided with the dust collector in Embodiment 2 of the present invention. FIG. 12 is a block diagram of the dust collector in Embodiment 2 of the present invention.

As shown in the figure, the dust collector according to the second embodiment of the present invention uses an air conditioner 11 as the first air blower.

The control unit 9 of the dust collector communicates with the air conditioner 11 and the dust collecting unit 8A using infrared light communication.

Detailed explanation will be given using drawings. In addition, about the structure similar to Embodiment 1, the same code | symbol is provided and description is used.

In FIG. 11, the air conditioner 11 is provided in the vicinity of the ceiling 17 of the indoor wall surface 51. A specific example of the air conditioner 11 is an air conditioner. In FIG. 12, the louver 74 </ b> C of the air conditioner 11 changes the wind direction of the airflow 1 blown out from the air conditioner 11 to the vertical and horizontal directions. In the room, as in the first embodiment, a dust collecting portion 8A is provided on the floor surface 6. In addition to the dust collection part 8 shown in Embodiment 1, the dust collection part 8A can blow out the airflow 1 in the left-right direction by the louver 87A. In FIG. 11, the left-right direction is a direction composed of α1 and β1.

In FIG. 12, the control unit 9 transmits a control signal from the first communication unit 82 to the control unit 72C of the air conditioner 11 via the second communication unit 71C. The control signal is transmitted by infrared light. If the first communication unit 82 has a so-called learning-type remote control function, the air conditioner 11 can be used as the dust collector of the second embodiment even if it is an existing air conditioner. The learning type remote controller stores the signal pattern of the infrared remote controller. Based on the control signal received by the second communication unit 71C, the control unit 72C adjusts the air volume and the wind direction of the air flow 1 to be blown out.

In addition, if the 1st communication part 82 performs information transmission using infrared light, cooperation with the existing infrared remote control corresponding | compatible apparatus other than the air conditioner 11 will be attained.

The operation and action of the dust collector configured as described above will be described below.

FIG. 13 shows an operation flow of the dust collector according to the second embodiment. The dust collector 8A of the dust collector is activated. The dust detector 81 provided in the dust collector 8A starts detecting the dust 2 floating in the room (step 11). If the dust detection part 81 detects the dust 2, the control part 9 will calculate the control signal for producing | generating the dust collection airflow 10 which is required. The control unit 9 transmits a control signal to the air conditioner 11 via the first communication unit 82. At the same time, the control unit 9 starts the operation of the blower fan 83 included in the dust collection unit 8A. The air conditioner 11 and the dust collecting unit 8A form the air currents 1 and 3 with the instructed air volume and direction based on the control signal calculated by the control unit 9 (step 12).

After a predetermined time has elapsed (step 13), the control unit 9 changes the operating conditions (step 14). Further, after a predetermined time has elapsed (step 15), the control unit 9 detects the remaining state of the dust 2 in the room using the dust detection unit 81 (step 16). The predetermined time set in step 13 and step 15 may be about 1 minute. If the control part 9 detects that the dust 2 exists in a room, the operation | movement after step 12 will be repeated.

On the other hand, if the control unit 9 cannot detect the presence of the dust 2 in the room, the air conditioner 11 and the dust collecting unit 8A are stopped after a predetermined time (step 17) (step 18). The predetermined time set in step 17 may be about 2 minutes. Thereafter, the control unit 9 returns to the detection waiting operation for the dust 2 in the room.

Here, the relationship between the airflows 3 and 1 blown out by the dust collection unit 8A and the air conditioner 11 and the dust collection airflows 10C and 10D formed by these airflows will be described. A dust collection air flow 10C is shown in FIG. A dust collection air flow 10D is shown in FIG.

FIG. 14 is a longitudinal sectional view of the indoor space explaining the operation of the dust collecting airflow 10E in the vertical direction, and FIGS. 15 and 16 are transverse sectional views of the indoor space explaining the operation of the dust collecting airflows 10F and 10G in the horizontal direction. Show. Table 2 shows the control contents instructed by the control unit 9 to each unit constituting the dust collector.

In FIG. 14, the airflow 3 blown out by the dust collecting portion 8A is upward (α2 to α1) in the vertical direction. The airflow 1 blown out by the air conditioner 11 is downward (δ1 to δ2) in the vertical direction.

The airflow 3 blown out from the dust collecting part 8A reaches the ceiling 17. The airflow 3 reaching the ceiling 17 flows toward the air conditioner 11 along the ceiling 17. This airflow 3 is sucked into the air conditioner 11. The air conditioner 11 blows the airflow 1 toward the floor surface 6. The airflow 1 flows along the floor surface 6 and is sucked into the dust collecting portion 8A. The dust 2 sucked together with the airflow 1 is removed from the airflow 1 sucked into the dust collecting portion 8A. The airflow 1 from which the dust 2 has been removed is blown out again as the airflow 3 from the dust collecting portion 8A. In this way, a dust collection air flow 10E circulating in the room is formed.

In Table 2, the control of pattern C is as follows. In FIG. 15, the airflow 3 blown out by the dust collection unit 8A is on the right side (β1 to α1) in the horizontal direction. The airflow 1 blown out by the air conditioner 11 is on the right side (δ1 to γ1) in the horizontal direction.

FIG. 15 shows a dust collection air flow 10F formed counterclockwise when the room 5 is viewed from above.

The dust collecting unit 8A blows out the airflow 3 toward the wall surface 52. The blown airflow 3 flows along the wall surface 52 and is sucked into the air conditioner 11. The air conditioner 11 blows the airflow 1 toward the wall surface 50. The airflow 1 flowing along the wall surface 50 reaches the wall surface 53. The airflow 1 that has reached the wall surface 53 flows along the wall surface 53. The airflow 1 is sucked into the dust collecting unit 8A. The dust 2 sucked together with the airflow 1 is removed from the airflow 1 sucked into the dust collecting portion 8A. The airflow 1 from which the dust 2 has been removed is blown out again as the airflow 3 from the dust collecting portion 8A. In this way, a dust collection air flow 10F circulating in the room is formed.

When the dust collection airflow 10E and the dust collection airflow 10F are synthesized, a dust collection airflow 10C shown in FIG. 11 is obtained. The dust-collecting airflow 10C is an airflow (δ1 to γ2) that is inclined downward to the right when viewed from the wall surface 51. This airflow circulates in the room.

In Table 2, the control of pattern D is as follows. In FIG. 16, the airflow 3 blown out by the dust collection unit 8A is on the left side (α1 to β1) in the horizontal direction. The airflow 1 blown out by the air conditioner 11 is on the left side (γ1 to δ1) in the horizontal direction.

FIG. 16 shows a dust collection airflow 10G formed clockwise when the room 5 is viewed from above.

The dust collecting unit 8A blows out the airflow 3 toward the wall surface 50. The blown airflow 3 flows along the wall surface 50 and is sucked into the air conditioner 11. The air conditioner 11 blows the airflow 1 toward the wall surface 52. The airflow 1 flowing along the wall surface 52 reaches the wall surface 53. The airflow 1 that has reached the wall surface 53 flows along the wall surface 53. The airflow 1 is sucked into the dust collecting unit 8A. The dust 2 sucked together with the airflow 1 is removed from the airflow 1 sucked into the dust collecting portion 8A. The airflow 1 from which the dust 2 has been removed is blown out again as the airflow 3 from the dust collecting portion 8A. In this way, a dust collection air flow 10G circulating in the room is formed.

If the dust collection airflow 10E and the dust collection airflow 10G are synthesized, a dust collection airflow 10D shown in FIG. 17 is obtained. The dust collection airflow 10D becomes an airflow (α2 to β1) having an inclination to the upper right side when viewed from the wall surface 53. This airflow circulates in the room.

As described above, in the second embodiment, the control unit 9 detects the dust 2 floating in the room using the dust detection unit 81 provided in the dust collection unit 8A.

The control unit 9 operates the dust collection unit 8 </ b> A and the air conditioner 11 in cooperation based on the detection state of the dust 2. The dust collecting unit 8 </ b> A forms the airflow 3, and the air conditioner 11 forms the airflow 1. The dust collection airflows 10C and 10D are formed by combining the airflows 3 and 1. That is, the control part 9 forms dust collection airflow 10C, 10D which circulates the whole room by switching the air volume and the wind direction of the dust collection part 8A and the air conditioner 11 every predetermined time. As a result, the dust 2 floating in the room can be efficiently removed.

In the present embodiment, the dust collector has been described with a configuration that mainly uses one dust collecting unit 8A and one air conditioner 11 as the first air blowing unit. What is necessary is just to select the structure of a dust collector suitably according to the magnitude | size, shape, etc. of the room 5. FIG.

The operating conditions of the dust collector were described using two patterns, Pattern C and Pattern D. The operating conditions for forming the dust-collecting airflows 10C and 10D may change the airflow timely. For example, the air volume is gradually increased over a predetermined time. When the airflow reaches the maximum airflow, gradually reduce the airflow. Thus, if the air volume of the dust collection airflows 10E, 10F, and 10G flowing in the room changes, the state of the dust collection airflows 10C and 10D flowing in the room changes. If the state of the dust collection airflows 10E, 10F, and 10G flowing through the room changes, it becomes easy to form the dust collection airflows 10C and 10D flowing through the entire room.

(Embodiment 3)
FIG. 18 is a perspective view of a room provided with the dust collector in Embodiment 3 of the present invention. FIG. 19 is a block diagram of the self-propelled cleaner in the third embodiment of the present invention.

As shown in the figure, the dust collector according to the third embodiment of the present invention further includes a self-propelled cleaner 12 with respect to the configuration of the first embodiment. The self-propelled cleaner 12 moves in the room. Self-propelled cleaner 12 removes garbage 2A which is the 2nd dust which exists in the room.

The control unit 9 controls the blower 7A and the dust collecting unit 8. The air blower 7 </ b> A and the dust collecting unit 8 combine the air current 1 and the air current 3 to form a dust collecting air current 10. The controller 9 controls the self-propelled cleaner 12 in accordance with the operations of the blower 7 </ b> A and the dust collector 8.

Moreover, the control part 9 operates the self-propelled cleaner 12 every time the air blower 7A and the dust collecting part 8 operate for a predetermined time.

Detailed explanation will be given with drawings. In addition, about the structure similar to Embodiment 1, the same code | symbol is provided and description is used.

In FIG. 19, the self-propelled cleaner 12 includes a main body 21, a traveling unit 27 that causes the main body 21 to travel, a cleaning unit 34 that cleans the room, and a fourth communication unit 33. The self-propelled cleaner 12 can move by controlling itself. The self-propelled cleaner 12 cleans the room while moving. The self-propelled cleaner 12 uses the fourth communication unit 33 to communicate with the second communication unit 71 </ b> A provided in the blower 7 </ b> A and the first communication unit 82 provided in the dust collecting unit 8.

The main body 21 includes a control unit 25 that is a second control unit that transmits a control signal to the traveling unit 27 based on detection results of each detection unit described later. The control unit 25 is configured by a microcomputer or the like.

In the third embodiment, the traveling unit 27 that has received a control signal from the control unit 25 moves the main body 21 using a pair of left and right main wheels 29 and one slave wheel 30. As a specific example of each detector, the main body 21 of the third embodiment includes an obstacle detector 22, a direction detector 23, a distance detector 24, a position detector 26, and a timer 32.

The obstacle detection unit 22 detects whether there is an obstacle in the room. When there is an obstacle in the room, the obstacle detection unit 22 detects the distance between the obstacle present in the room and the main body 21. As a specific example, the obstacle detection unit 22 includes an infrared sensor or an ultrasonic sensor. By using these sensors, it is possible to detect whether an obstacle exists in the room without contact. Further, when an obstacle exists in the room, the distance between the main body 21 and the obstacle can be detected without contact by using these sensors.

The direction detection unit 23 detects an angle at which the main body 21 rotates and a direction in which the main body 21 moves. As a specific example, the direction detection unit 23 includes a gyro sensor that outputs a signal proportional to the angular velocity, and a circuit that integrates and converts the signal output from the gyro sensor into an angle.

The distance detection unit 24 calculates and detects the distance traveled by the main body 21 based on the diameter of the main wheel 29 recorded in advance and the actual number of rotations of the main wheel 29. As a specific example, the distance detection unit 24 calculates a movement distance by connecting a rotary encoder to the pair of left and right main wheels 29 and measuring the number of rotations of the 29 main wheels.

The position detection unit 26 calculates and detects the current location of the main body 21 based on the detection result of the direction detection unit 23 and the detection result of the distance detection unit 24. The position detection unit 26 records the locus of movement of the main body 21. As a specific example, the position detection unit 26 previously stores the room shape by replacing it with a two-dimensional map coordinate. The position detection unit 26 calculates the position of the main body 21 from the detection results of the direction detection unit 23 and the distance detection unit 24. The position detection unit 26 applies the calculated position of the main body 21 to the map coordinates. The position detector 26 detects the position of the main body 21 from the coordinates on the fitted map.

The timer 32 calculates and detects the energized time after receiving the signal from the controller 9. As a specific example, the time measuring unit 32 is configured by using a clock function of a microcomputer configuring the control unit 25.

Furthermore, the main body 21 of the third embodiment has a buffer unit 28 and an input unit 31.

The buffer unit 28 is attached to the outer periphery of the main body 21 and detects the presence or absence of contact with an obstacle. In the third embodiment, the buffer portion 28 is attached in front of the main body 21. As a specific example, the buffer portion 28 is configured by a bumper formed of foamed rubber, rigid foamed urethane, or the like.

The input unit 31 is used when there is a person who is a user. The input unit 31 is used for input instructions for starting and stopping the main body 21 or changing the setting of each function. About the dust collector comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

In the third embodiment, when the dust collection unit 8 is activated, the dust detection unit 81 provided in the dust collection unit 8 starts detecting the presence or absence of the dust 2 floating in the room. When the dust detection unit 81 detects the dust 2, the control unit 9 transmits a control signal to the blowers 7 </ b> A and 7 </ b> B and the dust collection unit 8 based on the detection result of the dust detection unit 81 as in the first embodiment. Based on the control signal from the control unit 9, the blowers 7 </ b> A and 7 </ b> B and the dust collection unit 8 form a dust collection airflow 10 that circulates in the room. The dust 2 in the room is collected by the dust collection airflow 10 into the dust collection unit 8. After the dust detection unit 81 no longer detects the dust 2, the control unit 9 operates the blowers 7A and 7B and the dust collection unit 8 until a predetermined time elapses. After the predetermined time has elapsed, the control unit 9 stops the blowers 7A and 7B and the dust collecting unit 8. In the third embodiment, the predetermined time is about 2 minutes.

Further, after a predetermined time has elapsed, the control unit 9 transmits a control signal from the first communication unit 82 to the fourth communication unit 33. The self-propelled cleaner 12 transmits the received control signal from the fourth communication unit 33 to the control unit 25. The control signal may include a detection result of the dust detection unit 81 and the like. Self-propelled cleaner 12 is started based on this control signal. Self-propelled cleaner 12 starts cleaning floor 6 based on the received control signal. In the third embodiment, the fixed time is about 5 minutes. Infrared light communication was used for transmission from the first communication unit 82 to the fourth communication unit 33. Hereinafter, the operation of the self-propelled cleaner 12 will be described.

The self-propelled cleaner 12 moves forward in a predetermined direction after activation. The self-propelled cleaner 12 moves forward in the traveling direction until the obstacle detection unit 22 detects the presence of an obstacle within a predetermined distance. When the obstacle detection unit 22 detects the presence of an obstacle within a predetermined distance, the control unit 25 transmits a control signal to the traveling unit 27 so as to stop the self-propelled cleaner 12. In the third embodiment, the predetermined distance is 10 cm. After the self-propelled cleaner 12 stops, the control unit 25 rotates the self-propelled cleaner 12 by a predetermined angle based on the detection result of each detection unit described above.

The control unit 25 detects the rotation angle of the main body 21 based on the detection result of the direction detection unit 23. The control unit 25 rotates the self-propelled cleaner 12 while detecting the rotation angle of the main body 21. The control unit 25 controls the traveling unit 27 based on the detection result of the direction detection unit 23. When the control unit 25 rotates the pair of main wheels 29 in opposite directions, the control unit 25 rotates the main body 21. In the third embodiment, the self-propelled cleaner 12 rotates 90 degrees to the left with respect to the traveling direction described above. At this time, the control unit 25 controls the traveling unit 27 to rotate the left side of the main wheel 29 backward and the right side of the main wheel 29 forward. When the direction detection unit 23 detects that the self-propelled cleaner 12 has rotated 90 degrees to the left, the control unit 25 stops the traveling unit 27. Thereafter, the control unit 25 advances the self-propelled cleaner 12 again. Then, the self-propelled cleaner 12 moves forward again until the obstacle detection unit 22 detects the presence of the obstacle. By repeating this operation, the self-propelled cleaner 12 cleans the room. The self-propelled cleaner 12 performs cleaning for a preset time according to the size of the room.

When the self-propelled cleaner 12 cleans the floor surface 6, the dust 2 </ b> A that cannot be collected by the dust collecting airflow 10 is removed by the self-propelled cleaner 12. Specifically, the self-propelled cleaner 12 is optimal for removing the dust 2 </ b> A that is heavy like sand and cannot be collected by the dust collection airflow 10.

As is clear from the above description, the dust collector described in the third embodiment has the following operational effects.

The control unit 9 controls the blowers 7A and 7B and the dust collection unit 8 to form a dust collection airflow 10 that circulates in the room. The dust collection airflow 10 moves the dust 2 floating in the room to the dust collection unit 8. The dust collecting unit 8 efficiently collects the collected dust 2.

On the floor surface 6, dust 2A, which is heavy like sand, is accumulated. The dust 2 </ b> A that cannot be moved by the dust collection airflow 10 is removed by the self-propelled cleaner 12.

The dust 2 that can be collected by the dust collection airflow 10 and the dust 2A that cannot be collected by the dust collection airflow 10 are removed by this configuration.

In the above description, the self-propelled cleaner 12 has been described using an example in which the blower 7A, 7B and the dust collecting unit 8 are started after a certain period of time each time after stopping. However, depending on the indoor state, the self-propelled cleaner 12 may be activated after the blowers 7A and 7B and the dust collecting unit 8 are operated a predetermined number of times.

Specifically, the blowers 7A and 7B and the dust collecting unit 8 operate for 10 minutes. Thereafter, the fans 7A and 7B and the dust collecting unit 8 are stopped for 5 minutes. Thereafter, the self-propelled cleaner 12 is activated to remove the dust 2A for 5 minutes. Control that repeats this series of operations is referred to as pattern 1.

Next, the blowers 7A and 7B and the dust collecting unit 8 operate for 10 minutes. Thereafter, the fans 7A and 7B and the dust collecting unit 8 are stopped for 5 minutes. Thereafter, the fans 7A and 7B and the dust collecting unit 8 are activated. After repeating such an operation for 3 hours, the self-propelled cleaner 12 is activated to remove the dust 2A for 5 minutes. Control related to this series of operations is referred to as pattern 2.

If the room provided with the dust collector described in Embodiment 3 can be accommodated by the pattern 2, power consumption for operating the dust collector can be suppressed.

Furthermore, in the above description, the dust collector 8 and the self-propelled cleaner 12 are configured separately. However, the third embodiment is not limited to this separate configuration, and the dust collection unit 8 and the self-propelled cleaner 12 may be integrated. With this configuration, both dust 2 floating in the room and heavy garbage 2A can be removed by the self-propelled cleaner 12 having a dust collecting function.

(Embodiment 4)
FIG. 20 is an explanatory diagram for explaining room coordinates stored in the position detection unit in the dust collector in Embodiment 4 of the present invention. FIG. 21 is a perspective view of a room provided with the dust collector in Embodiment 4 of the present invention.

The fourth embodiment relates to further control of the self-propelled cleaner 12 described in the third embodiment. About the structure similar to Embodiment 3, the same code | symbol is provided and description is used.

The floor 6 is provided in the room. The floor surface 6 is divided into an X axis and a Y axis that are orthogonal in the indoor horizontal direction.

The control unit 25 as the second control unit has a position detection unit 26. The position detection unit 26 recognizes a predetermined position where the dust 2A that is the second dust is located. Recognition of the predetermined position is performed using the X-axis and Y-axis coordinates of the floor surface 6. The control unit 25 moves the self-propelled cleaner 12 to this predetermined position.

Details of the control will be described using the drawings. FIG. 22 shows the details of Step 2 in FIG. 10 described in the first embodiment.

The dust detection unit 81 detects whether dust 2 exists in the room. When the dust 2 exists in the room, the control unit 9 performs a step of blowing the air flow 1 as the first air flow into the room (step 21). The controller 9 sucks indoor air and removes the dust 2 that is the first dust contained in the air. The controller 9 performs a step of blowing the air from which the dust 2 has been removed into the room. The air blown into the room is the air flow 3 that is the second air flow (step 22). The controller 9 performs a step of synthesizing the airflow 1 and the airflow 3 to form the dust collection airflow 10 (step 23). The controller 9 confirms whether or not the synthesized dust collection airflow 10 is formed (step 24). When the synthesized dust collection airflow 10 is not the predetermined dust collection airflow 10, the control unit 9 performs a step of adjusting the airflow 1 and the airflow 3 (step 25). When the synthesized dust collection airflow 10 is a predetermined dust collection airflow 10, Step 3 is performed in FIG.

In the dust collector described in the fourth embodiment, after the dust airflow 10 is formed and the dust 2 is removed, the dust collector removes the dust 2A using the following control.

After the control shown in FIG. 10, the control unit 9 performs the control shown in FIG. After performing the step of forming the dust collecting airflow 10 described above, a step of calculating a predetermined position in the room where the dust 2A as the second dust is located is performed (step 31). The control part 9 performs the step which moves the self-propelled cleaner 12 to a predetermined position so that the self-propelled cleaner 12 can remove the waste 2A (from step 32 to step 34).

When the self-propelled cleaner 12 moves to a predetermined position, the control unit 9 performs a step of causing the self-propelled cleaner 12 to remove the garbage 2A (step 36).

The step in which the self-propelled cleaner 12 removes the dust 2A is as follows.

The indoor state shown in FIG. 21 is stored in the position detector 26 as follows. The coordinates representing the indoor position are P0 as the reference position in FIG. The X axis is defined such that the coordinates increase to the left. The maximum value of the X axis is n. The Y axis is defined such that the coordinates increase upward. The maximum value of the Y axis is p. If one scale of the X-axis and Y-axis coordinates is approximately the same size as the main body 21 of the self-propelled cleaner 12, control by the control unit 25 is facilitated. In the fourth embodiment, one scale is 30 cm.

21 corresponds to the coordinates indicated by the same reference numerals in FIG. 20. In such a position detection unit 26, the indoor state shown in FIG. 21 is stored as follows.

The positions of the dust collection unit 8, the chest 40 and the table 41 provided in the room are recorded in the position detection unit 26. If there is other furniture, the position relating to the furniture is recorded in the position detection unit 26.

The positions where the garbage 2A that is not collected in the dust collection airflow 10 is accumulated are defined as the priority areas A and B. The priority areas A and B may be calculated by simulation based on the arrangement of the dust collection unit 8, the chest 40 and the table 41. Specifically, as a result of the control unit 9 forming the dust collection airflow 10, the position where the airflow of the dust collection airflow 10 is weak and the position where the dust 2A forms a puddle are extracted as priority areas A and B. In the priority areas A and B, the position where the dust 2A actually exists may be recorded based on the result of using the dust collector. The positions of the priority areas A and B are recorded in the position detection unit 26.

In addition, when performing such recording, the user may perform an input operation to the position detection unit 26. The self-propelled cleaner 12 may recognize the state of the room by moving in the room and record the result.

The self-propelled cleaner 12 includes a direction detection unit 23 and a distance detection unit 24. If the self-propelled cleaner 12 moves in the room, the self-propelled cleaner 12 is controlled by the rotation angle of the main body 21 detected by the direction detector 23 and the movement distance of the main body 21 detected by the distance detector 24. A movement trajectory is extracted. The extracted movement locus of the self-propelled cleaner 12 is recorded in the position detection unit 26 as coordinates shown in FIG.

The control of the fourth embodiment will be described in detail with reference to the drawings. As described in the third embodiment, the control unit 9 stops the dust collection unit 8 after a predetermined time has elapsed without the dust detection unit 81 detecting the dust 2. After the dust collection unit 8 stops, the self-propelled cleaner 12 is activated by the control unit 9. When the self-propelled cleaner 12 is activated, the control unit 25 checks the presence / absence of a pre-recorded priority area.

When there are a plurality of priority areas as shown in the fourth embodiment, the control unit 25 calculates the order of priority areas to be processed by the self-propelled cleaner 12 based on the coordinates of the priority areas. In the fourth embodiment, the self-propelled cleaner 12 located at P0 performs processing in the order of the priority area A near P0 and then the priority area B. The control unit 25 calculates the coordinates A1 (4, 2) of one end of the priority area A (step 31). Next, the control unit 25 calculates the coordinates where the self-propelled cleaner 12 is located (step 32). The coordinates where the self-propelled cleaner 12 is located are compared with the coordinates of one end of the priority area A (step 33). If the comparison results do not match, the control unit 25 controls the traveling unit 27 based on the coordinates of the position detection unit 26 and moves the self-propelled cleaner 12 to the coordinate A1 (step 34). When the comparison result is coincident, the self-propelled cleaner 12 starts to remove the dust 2A (step 35).

The control unit 25 detects the coordinate A2 (6, 2) that is the end point of the priority area A stored in the position detection unit 26 (step 36). The control unit 25 continues to remove the dust 2A aiming at the coordinate A2 which is the end point (from step 37 to step 39). The self-propelled cleaner 12 arrives at the coordinate A2, and the self-propelled cleaner 12 removes the garbage 2A. Self-propelled cleaner 12 stops removal of garbage 2A (Step 40). Thereafter, the control unit 25 confirms the presence / absence of the next priority area (step 41). In the fourth embodiment, the priority area B exists. The control unit 25 moves the self-propelled cleaner 12 to the coordinate B1 of the priority area B (again, to step 31). If there is no other important area, the removal of the dust 2A is finished (step 42).

Thereafter, when the removal of dust in the priority area B is completed, the control unit 25 moves the self-propelled cleaner 12 to the reference position P0. After the self-propelled cleaner 12 reaches the reference position, the self-propelled cleaner 12 stops.

By the above operation, the self-propelled cleaner 12 can clean the priority area of the indoor floor surface. As a result, the dust 2A that cannot be collected by the dust collection airflow 10 circulating in the room is removed.

If the above-described first to fourth embodiments are appropriately combined, the following operational effects can be obtained.

The dust collector forms a dust collection air flow 10 that circulates in sequence throughout the entire area of the room, and collects dust 2 floating in the room.

Dust that cannot be collected with a dust-collecting airflow and accumulated on the floor, and dust that accumulates at locations where the dust-collecting airflow does not reach sufficiently, are removed using a self-propelled cleaner. By removing such two-stage dust, the removal rate of dust existing in the room can be improved.

Note that the present invention is not limited to the embodiment described above. Any specific means may be used as long as the same effects can be obtained.

(Embodiment 5)
Next, the dust collector in Embodiment 5 of this invention is demonstrated. Embodiments 1 to 4 described above can be implemented by causing a program recorded in a storage medium to cooperate with hardware that is each component.

Hardware includes a storage device such as a CPU, RAM, ROM, and HDD, a computer or an electronic device having an I / O, a server, and the like. The hardware may be a microcomputer. Magnetic media and optical media are used as recording media.

If Embodiments 1 to 4 can be realized by a program, this program can be distributed using a communication line such as the Internet. It is easy to update functions by distributing new programs.

The dust collector according to the present invention can efficiently collect relatively light dust by the dust collection airflow. Furthermore, the dust collector can further collect dust by a self-propelled cleaner that autonomously moves heavy objects such as sand. For example, it is useful for use in a clean room as a manufacturing facility or a sterile room as a hospital or research facility.
