Description

humidifier

technical field

The present invention relates to a humidifying device having a humidifying function without water supply which is most suitable for use with an air conditioner body.

Background technique

As an air conditioner, in addition to the cooling function and the heating function, most of them basically have the air supply function and the dehumidification function. However, especially in various seasons, the degree of dryness becomes extremely high due to the low humidity, and the humidification effect cannot be achieved during the heating operation.

Therefore, a dedicated humidifier is made and sold, which is a small desktop type. On the contrary, since the main body of the air conditioner has refrigeration cycle structural parts and auxiliary parts, a large wall-mounted air conditioner in which the indoor unit is installed on the wall of the room to be conditioned is mostly used.

If there are both the air conditioner body and the humidifier, the required installation space becomes large, and it takes time to replenish the humidifier with water at appropriate intervals, and the air conditioner body must also be maintained individually.

Therefore, the air conditioner is increasingly required to have a humidifying function, and it is actually provided as a product. For example, a humidifier is housed inside an indoor unit of an air conditioner, or inside an outdoor unit.

In such a humidifier-integrated air conditioner, it is necessary to strike a balance between the humidification performance of the humidifier and the air conditioning performance of the air conditioner. Do not only make the air conditioning performance outstanding, or only make the humidification performance outstanding.

The structural components of the humidifier are integrally mounted on the air conditioner body, and the size of the humidifier body cannot be easily changed.

However, in order to obtain a higher humidification efficiency, there are various selection conditions, such as changing and adjusting the air supply volume, changing and adjusting the absorbed amount of moisture, or changing the released amount of absorbed moisture during adjustment.

Even if the structural parts are partially changed according to these selection conditions, it takes a lot of work because the whole is integrated into a unit. In this case, there is a problem that it is difficult to cope with redesigning and correcting a new humidifier, and responding to high performance.

Summary of the invention

The present invention was made with the above circumstances in mind, and an object of the present invention is to provide a humidifier that divides assembly of structural parts into units, easily responds to high performance, and contributes to cost reduction.

The humidifying device of the present invention has: a casing frame body provided with a suction port and a blowing port for indoor air; The non-water supply humidification function that absorbs the moisture contained in the taken-in external air and releases it to the indoor air to humidify. The above-mentioned device body has a plurality of device bodies that are unitized with non-water supply humidification function parts. These multiple device bodies are mutually They have approximately the same area and are assembled so as to overlap each other in the thickness direction.

Therefore, it is possible to obtain a humidifier that divides assembly of structural components into units, easily supports high performance, and contributes to cost reduction.

In the lower portion of the back side of the frame portion 7A, a bush 14 formed in a substantially U-shape is separated from the frame portion 7A, and the bush can be detached as necessary.

On the left and right sides of the liner 14, there are so-called dismantling parts 15 formed as rectangular cutouts, depending on the arrangement conditions of the humidifier K facing the indoor unit A, or the piping holes for the penetration of the pipes and refrigerant piping. The positional relationship can be removed to ensure the necessary openings.

The above-mentioned device body 6 will be described with reference to FIG. 3 and FIG. 4 .

A first air filter 16 (the filter portion is omitted) is detachably fitted in the front substantially central portion, and a second air filter 17 is detachably fitted in the side portion at a position lowered one level. Each handle part is indicated, and the actual filter part is inserted on the surface or inside of the device main body 6 .

The filter portion of the first air filter 16 extends to a position facing the suction port 4 on the upper surface of the front panel 7, and removes dust mixed in the indoor air. The filter part of the said 2nd air filter 17 is arrange|positioned in the introduction part of the outside air mentioned later, and removes the dust mixed in the outside air.

The handles of these first and second air filters 16 and 17 are positioned opposite to an opening for attaching and detaching the filter, not shown, provided on the front surface of the front panel 7, and are opened by opening the decorative panel 8. It is exposed and can be attached and detached from the indoor side on the front side.

In addition, an indoor air outlet 18 is provided on the lower front portion of the device main body 6, and is opened at a portion facing the blow-out cover 3 provided on the lower front portion of the front panel 7 described above.

FIG. 5 shows an exploded view of the above-mentioned device body 6 .

The device main body 6 is composed of a first device body 20 shown in the center of the figure and a second device body 50 shown on the left side, and is also composed of a combination with an electrical component box 60 shown on the right side of the figure.

The device body 6 has a non-water-supply humidification function of absorbing moisture contained in the taken-in outside air and releasing it to the room air for humidification. The first device body 20 and the second device body 50 are unitized. Electrical control components are accommodated in the electrical component box 60 .

The first device body 20 and the second device body 50 have substantially the same area and are assembled so as to overlap each other in the thickness direction. The electrical component box 60 described above is also assembled so as to overlap each other in the thickness direction of the first device body 20 and the second device body 50 .

In this way, the device body 6 is divided into three components of the first device body 20, the second device body 50, and the electrical parts box 60. Since they are made into a connected structure, the first device body 20 or the second device body can be made The size and performance of the 50 are combined to expand in the thickness direction. Therefore, there is an effect of reducing the number of parts, and the utilization of variable energy of each structural part corresponds to improvement of humidification performance.

As shown in FIGS. 6 and 7 , the first device body 20 is protruded with an air outlet body 21 that guides and discharges outside air taken into the device main body 6 to the outside. The opening end of the exhaust port body 21 faces the rear of the back side. An air inlet body 22 for introducing external air into the device body 6 protrudes from the second device body 50 . The opening end of the air supply port body 22 faces the rear of the back.

Owing to making such a structure, at the rear of the supply and exhaust port bodies 22, 21, the installation space of the unillustrated supply and exhaust ducts connected to the supply and exhaust port bodies can be fully ensured, and it is easy to form the exhaust pipes of the ducts. parts.

In addition, since the above-mentioned supply and exhaust port bodies 22 and 21 are provided on the lower front side of the device body 6 and protrude in parallel with each other, the installability of the supply and exhaust ducts and the humidifier K itself can be improved.

8 and 9 schematically show the structure of the device main body 6, and explain the arrangement structure of these components.

As the structural parts of the above-mentioned device body 6, there are: a humidity control element 23 that only absorbs moisture from the passing air and releases the moisture by heating; The processing side air blower 24; the regeneration side air blower 25 which introduces the indoor air to the humidity control element and blows it out into the room; the heater (heater) 26 which heats the humidity control element and releases the absorbed moisture.

The cylindrical body connected to the above-mentioned processing-side blower 24 is the exhaust port body 21 described above, and actually protrudes rearward from the lower end position inclined to a slope forming the housing of the processing-side blower 24 .

The processing side air blower 24 and the regeneration side air blower 25 are arranged on the same side with respect to the humidity control element 23 described above, and the heater 26 is arranged on the opposite side. Furthermore, the processing-side air blower 24 and the heater 26 are arranged in parallel with the humidity control element 23, and are in a state of substantially close contact with each other.

The regeneration-side air blower 25 is located on the side where the processing-side air blower 24 is arranged, and is arranged obliquely with respect to the humidity control element 23 . That is, the regeneration-side blower 25 is arranged in the inclined space portion constituting the housing of the processing-side blower 24 .

Since the processing-side air blower 24 and the regeneration-side air blower 25 blow air to the humidity control element 23, they must be disposed at positions basically in close contact with the humidity control element. Therefore, as shown by the double-dashed line in FIG. 8 , it may be considered to arrange the regeneration-side air blower 25 orthogonally on one side of the humidity control element 23 , and arrange the processing-side air blower 24 parallel to the humidity control element 23 .

However, in this case, it is necessary to maintain a necessary gap between the humidity control element 23 and the processing-side blower 24, which hinders overall miniaturization. In this regard, adopting the disposition structure of the present invention represented by the solid line, as a result, the dimension in the lateral direction (width) direction of the device body 6 can be shortened, and since the exhaust port body 21 can be arranged in the idle space, even if it is miniaturized, it will not make the Performance and mountability deteriorate.

Fig. 10 is an exploded view showing the components of the device main body 6 from the front side.

A main body unit 26 is provided approximately in the center of the figure, and a processing side blower unit 24S is provided on one side thereof, and the above-mentioned first device body 20 is constituted by combining them.

In addition, the above-mentioned air supply port body is protrudingly provided on the lower front side of the back side. On the upper part, a geared motor 27 serving as a rotational drive source of the above-mentioned humidity control element assembly 23S is attached, and a drive gear 28 is fitted on the rotation shaft of the motor.

The display LEDs of the above-mentioned display means are electrically connected to control electric components in the electric component box 60 . A part of the fan motor 24M of the process-side blower 24 protrudes from the side of the process-side blower assembly 24S, and the electrical component box 60 is formed with a recessed side that can house the protruding portion of the motor.

FIG. 11 shows an exploded view of the processing-side blower unit 24S.

Between the housing pair 29A, 29B after both division|segmentation, the processing side air blower 24 comprised from the fan motor 24M and the fan 24F is accommodated. By combining the housing pair 29A, 29B, a suction guide port 30a is formed on one side, and a partially protruding opening 30b of the fan motor 24M is provided on the other side.

The fixing plate 31 for mounting and supporting the processing-side air blower 24 is mounted on the housing 29B on the right side of the figure. The diameter of the above-mentioned fan 24F is approximately equal to the diameter of the above-mentioned suction guide port 30a, and the bell mouth 32 shown on the front side of the fan is actually separate from the fan, and is installed on the housing pair 29A, 29B in an appropriate way. .

In addition, port body forming portions 21 a , 21 b constituting the exhaust port body 21 by combining them are provided on lower end portions of the housing pair 29A, 29B.

FIG. 12 shows the body assembly 26 in exploded view.

It is formed by assembling the regeneration-side blower unit 25S, the first damper mechanism 32 and the second damper mechanism 33 with respect to the first main casing 31 .

On the back side of the first main casing 31, a recess (not shown) for accommodating the humidity control element unit 23S is formed, and a plurality of holes for guiding outside air and room air are provided inside. A gear cover 34 covering the upper drive gear 28 is provided at the upper portion, and a support portion 35 for accommodating the second damper mechanism 33 is provided at the lower portion.

In addition, in the vicinity of the support portion 35 in the first main casing 31, an opening portion 59a for a bypass circuit is provided to form air circulation together with the above-mentioned plurality of hole portions, and it is in a state of being opened and closed by a damper mechanism described later. .

The regeneration-side blower unit 25S is mounted with the regeneration-side blower 25 inclined to the fan holder 36, and the indoor air suction port 18 is opened on the suction side thereof. That is, the fan holder 36 has the room air suction port 18 provided facing the periphery of the regeneration-side blower 25, and the blowing guide port (not shown) provided facing the central part of the blower.

The regeneration-side air blower 25 is installed and fixed on the fan fixing member 36 through a pressing plate 37 . In addition, a stepping motor 38 serving as a drive source for the first damper mechanism 32 and the second damper mechanism 33 is attached and fixed to the fan holder 36 .

FIG. 13 shows an exploded view of the humidity control element assembly 23S.

The humidity control element 23 is formed in a disc shape with a predetermined thickness, and has a hole 23a in the center. Only moisture is absorbed by passing air containing moisture from one side to the other side. In addition, it has the characteristic of releasing the temporarily absorbed moisture by heating the part.

The rotor case IN39a is fitted into the central hole portion 23a of the humidity control element 23, and the rotor case OUT39B is fitted into the outer peripheral portion. Flanges a, b are formed along one side edge of each housing 39A, 39B, and are locked to the inner and outer peripheral edges of one side surface of the humidity control element 23 .

Moreover, the rotor cover 40 covers the other surface side of the humidity control element 23, and the center part is attached to the said rotor case IN39A with the attachment screw. Since the outer peripheral part of the rotor cover 40 is fitted in the rotor case OUT39B, the humidity control element 23 is sandwiched from both sides.

The grille portion c is radially and concentrically formed from the center portion of the rotor cover 40 toward the outer periphery, and one side surface of the humidity control element 23 is basically exposed. The other side of the humidity control element 23 has only the rotor housing IN39A and OUT39B, so both sides are exposed.

A gear portion 41 is provided along the outer peripheral surface of the rotor cover 40 and meshes with the drive gear 28 of the geared motor 27 described above. In a state assembled as the humidity control element assembly 23S, the flat surface of the rotor case OUT39B and the gear part 41 of the rotor cover 40 are formed in parallel on the outer peripheral surface.

FIG. 14 is an exploded view of the second device body 50 .

The second device body 50 is composed of a combination of a second main casing 51, an inlet body cover 52, and a heater unit 26S.

The second main casing 51 is provided with a plurality of openings through which outside air or room air flows, and the heater unit 26S covers one of the openings. The filter part 17F of the said 2nd filter 17 covers the remaining opening part.

The above-mentioned geared motor 27 is installed on the top, and the drive gear 28 embedded on its rotating shaft protrudes from the inside. In addition, the air supply port body 22 is integrally protruded from the lower end portion of the suction port body cover 52 .

As the device main body 6 constructed in this way, the blower fan that generates the wind that supplies the moisture (humidity) from the air to the humidity control element 23 is the above-mentioned processing side blower 24, and the moisture (humidity) that comes from the humidity control element 23 The blower fan on the side that releases and supplies moisture to the air is the above-mentioned regeneration-side blower 25 .

One of the characteristics of the present invention is that the fan configurations of the processing-side air blower 24 and the regeneration-side air blower 25 are made to have different specifications from each other.

That is, the fan form of the air blower on the one side where the air passes through the building outer wall is made to have a stronger static pressure characteristic than the fan form of the other air blower. Specifically, the fan of the processing-side air blower 24 has stronger static pressure characteristics than the fan of the regeneration-side air blower 25 .

Generally, as a fan form, a multi-blade turbo fan, a multi-blade centrifugal fan, a propeller fan, a cross-flow fan, etc. are known. The hydrostatic characteristics are stronger in order of the preceding ones. Therefore, the fan of the processing side air blower 24 is a multi-blade turbo fan with high static pressure characteristics, and the fan of the regeneration side air blower 25 is a multi-blade centrifugal fan.

In addition, for the description, two air blowers on the treatment side and the regeneration side are required to have the humidity control element 23 to constitute the non-water supply humidification function. From the standpoint of assembly, the structure can be simplified if the fan motors have the same capacity and the fans have the same shape.

However, depending on the air supply load and the installation environment, the required air volumes are different, and if the same air blower is used, one of them will become too large. Therefore, it is considered that, as fans of the same form, a fan with a larger diameter must be prepared for the one with a larger required air volume, or a fan motor with a different rotational speed range is used. In this case, there is a problem of causing an increase in the size of the housing and reduction in capacity.

In addition, the humidification function without water supply, especially for the heating period, must capture moisture from the outdoor air with low absolute humidity. Therefore, the necessary air volumes of the regeneration-side blower 25 and the treatment-side blower 24 are "regeneration-side blower 25<treatment-side blower 24", and on the treatment side, the blowing air passage is longer because it passes through the wall, so the blowing load is larger. .

As described above, the air volume of the processing side air blower 24 is made into a fan with high static pressure characteristics such as a multi-blade turbo fan, and the fan of the regeneration side air blower 25 is made into a multi-blade centrifugal fan with a smaller static pressure characteristic, etc. , can obtain the optimization of the blowing characteristics of each blower and the miniaturization of the fan, and can realize the humidification characteristic with high efficiency.

In addition, since the static pressure characteristics of the regeneration-side blower 25 and the processing-side blower 24 are different, when a "quiet mode" such as night is selected and only the rotational speed of the fan of the regeneration-side blower 25 is reduced, the regeneration-side blower 25 and the treatment-side blower 24 The static pressure difference becomes larger, and the air volume on the regeneration side will not exceed the extreme.

Therefore, as shown in Table 1 below, the air volume control of the regeneration-side blower 25 can be linearly performed by linking the regeneration-side blower 25 and the processing-side blower 24 and controlling the mutual wind speed and rotational speed. In addition, as a comparative example, the following Table 2 shows an example in which only the rotational speed of the fan of the regeneration side air blower 25 is decreased in the "Static Mode" while performing the same control as in Table 1 in the "Hi Mode".

FIG. 15 schematically shows the air circuit in the humidifier K. As shown in FIG.

When the humidification mode is selected, the geared motor 27 rotates the humidity control element 23 at a low speed, and drives the processing-side blower 24 and the regeneration-side blower 25 to generate heat from the heater 26 . The outside air guided into the device main body 6 from the air supply duct 42 connected to the air supply port body 22 passes through a part of the humidity control element 23 .

At this time, moisture contained in the outside air is absorbed by the humidity control element 23 described above. In addition, outside air is exhausted to the outside from the exhaust duct 43 connected to the exhaust port body 21 by the process-side blower 24 .

Since the humidity control element 23 rotates at a low speed, the portion that absorbs moisture from the outside air faces the indoor air conduction side. At the same time, the room air is sucked into the device body 6 from the suction port 4 and passes through a part of the humidity control element 23 .

The heater 26 heats the humidity control element 23 to evaporate the absorbed moisture. The moisture evaporated from the humidity control element 23 is mixed with the room air conducted to the heater 26, and as a result, the room air blown into the room from the air outlet 2 is humidified.

In addition, in order to reliably partition the treatment side through which the outside air is conducted and the regeneration side through which indoor air is conducted in the humidity control element 23 , a sealing member 44 is provided as a separate member. That is, since the static pressure characteristics are different between the regeneration side and the treatment side, if there is a space gap between them, a so-called short circuit occurs. Therefore, occurrence of a short circuit can be prevented by having the above-mentioned sealing member 44 .

FIG. 16 schematically shows the arrangement of components of the device main body 6 .

The humidity control element 23 is located in the center, and the heater 26 is arrange|positioned at one side. An electrical component box 60 accommodating electrical control components (such as a microcomputer) 45 is arranged on the side opposite to the heater 26 side where the humidity control element 23 is interposed. The processing-side air blower 24 and the regeneration-side air blower 25 are arranged on the same side as the side where the electrical component box 60 of the humidity control element 23 is arranged.

These arrangement structures are selected from the case of an air conditioner having a conventional humidifier. That is, conventionally, a humidifier is integrally provided inside the indoor unit, and electrical control components having a function of controlling humidification are also arranged inside the indoor unit on the same side as the heater. Alternatively, a humidifier is integrally provided inside the outdoor unit. In this case, the electrical control components are separately arranged because there is little restriction on the arrangement space. However, electric control parts are arranged near the heater, so cooling devices such as radiators are provided.

However, when there are electric control parts near the heater, the leaked heat from the heater flows into the electric control parts, and there is a temperature rise of these parts or a temperature rise of the fan motor, and the adverse effect of heat cannot be avoided.

As mentioned above, by disposing the electric control parts 45 and the fan motors 24M and 25M of the respective blowers on both sides of the heater 26 with the humidity control element 23 interposed therebetween, the influence of the leakage heat from the heater 26 can be avoided. Each temperature rise can be suppressed.

In addition, the heater casing 46 which is a structure around the heater 26 is considered to be formed of a sheet metal material in terms of its heat resistance properties. Therefore, the heater case 46 made of this sheet metal has a large amount of heat dissipation.

Therefore, it is preferable not to arrange electrical components around the heater case 46 . Since the heat conductivity of the humidity control element 23 is low, a heat insulation effect can be obtained by making it arrange|position as shown.

As mentioned above in Fig. 1, a humidifier K is arranged side by side with the indoor unit A. Therefore, the humidifier K is limited by the space relative to the room, and at least it does not become the main cause of the temperature rise in the room. Therefore, by adopting the illustrated structure, it does not become a factor of temperature rise.

FIG. 17 shows the arrangement structure of the heater 26 in the second device body 50 . This figure removes the heater housing 46 in the heater assembly 26S. The device body 50 has a plurality of openings 47a, 47b, and the wind coming out of the opening 47a is guided to the other opening 47b as shown by the dotted arrow in the figure.

Between the openings 47a and 47b, there is a grille portion 48 radially provided from the center of the device body 50 toward the peripheral end. The aforementioned heater 26 is attached along substantially the entire length of the grille portion 48 . In addition, the above-mentioned humidity control element 23 is a disc body, and its central part coincides with the central part of the second device body 50 .

Therefore, the heater 26 is provided along the radial direction of the humidity-conditioning element 23, and the wind heated by the heater is guided through the humidity-conditioning element in a uniform state. The absorbed moisture is released evenly on the humidity control element 23, and the humidification efficiency can be improved.

18A to 18C are diagrams showing specific configurations of the heater 26 .

As shown in FIG. 18A , a plurality of cooling fins 54 are integrally provided on both sides of the heater body 53 with a narrow gap between them in the longitudinal direction.

As a form of the heater, a ceramic heater (also referred to as a cartridge humidifier) 26A shown in the cross section of FIG. 18B or a PTC heater 26B shown in the cross section of FIG. 18C can be used.

First, the ceramic heater 26A will be described, which has U-shaped casing guides 55a on both sides in the figure, and sandwiches the upper and lower parallel finned casings 55b from left and right. A ceramic heater element 56 is interposed between these finned casings 55b.

In the case of the PTC heater 26B, there are U-shaped housings 55a on both sides in the drawing, and a finned housing 57a with parallel upper and lower parts is sandwiched from left and right. A ceramic layer 57b is integrally stacked on the inner surface of these finned housings 57a to insulate against the PTC element 58 sandwiched between them.

In conventional heaters, the moisture absorbed in the humidity-conditioning element is heated by a nickel-chromium alloy wire heater to dehumidify it, and the velocity distribution of the wind passing through the heater is used to make it easier for the heater part where the wind velocity is slow to become Local high temperature, the worst case will appear red heat, fusing, and may even cause fire or electric leakage. Or when the blower on the regeneration side is abnormal, the wind passing through the heater is reduced, which may cause the nickel-chromium alloy wire to overheat.

On the contrary, since the above-mentioned ceramic heater 26A is an insulated element 56 covering the resistor body with ceramics, and is provided with a cooling fin 54, the hot air heated by the heater passes through the humidity-regulating element 23, and can be released reliably. Moisture absorbed by the humidity-conditioning element.

Compared with the conventional nickel-chromium alloy wire heater, the above-mentioned ceramic heater 26A is used, and by using the heat sink 54 with high thermal conductivity, the unevenness of the surface temperature of the heater caused by the wind speed distribution is reduced, and ignition or leakage can be suppressed. etc. bad situation. Since it is an insulating structure, it is structurally safe and durable.

In the case of the above-mentioned PTC heater 26B, the same effect as that of the ceramic heater 26A is obtained. In addition, when the air volume of the air passing through the heater 26B is reduced, the resistance value of the heater tends to be increased, and the heater capacity is reduced to reduce the heat generation value.

Therefore, the heater itself has a capacity control (self-sustaining) function, and can produce a heating capacity suitable for the air volume at the time. Because of high safety and no need for electrical capacity control, a heater control circuit is basically not required.

In any of the above, by providing the heat sink 54 in the ceramic heater 26A or the PTC heater 26B, the air passing through the heater can be efficiently heated.

Structurally, since the surface of the heater (heat sink) is insulated, the surface temperature is also lower than that of the nickel-chromium alloy wire heater, so the air passing through the heater made of sheet metal can reliably pass through the heat sink 54, and a highly efficient heating structure can be obtained , and high security.

19 and 20 show the arrangement structure of the first filter 16 and the second filter 17 .

That is, the first filter 16 for collecting and removing dust contained in the indoor air is disposed on the indoor air introduction side of the humidity control element 23 . The second filter 17 for collecting and removing dust contained in the outside air is disposed on the outside air introduction side of the humidity control element 23 . These first and second filters 16 and 17 are all detachable from the inside of the room, as described above.

And, the filter part 17F (not shown here) of the above-mentioned second filter 17, as shown in FIG. area expands.

Thus, by providing the first and second filters 16 and 17 on the air introduction side of the humidity control element 23, contamination of the air guided to the humidity control element 23 can be prevented and the life of the humidity control element can be extended. Since the filters 16 and 17 can be taken out from the front side, maintenance is easy.

Since the material of the filter part is non-woven fabric, it can prevent finer dust from entering. In addition, if the filter part is made into a net, it can be cleaned to ensure hygiene. By weaving anti-mildew and anti-bacteria agents on the filter net, the filter can have the effect of anti-mildew and anti-bacteria.

Fig. 21 schematically shows an air circuit for explaining switching from a humidification function to a ventilation function.

That is, switching between the humidification function and the ventilation function is configured by the first damper mechanism 32 and the second damper mechanism 33 . As described above, these first and second damper mechanisms 32 and 33 are connected to each other, and the stepping motor 33 is used as a drive source to interlock with each other.

Since the first damper mechanism 32 is provided to face the air inlet body 22 , it is located on the outside air introduction side with respect to the humidity control element 23 . The introduction of outside air into the device main body 6 is opened and closed by the rotation of the stepping motor 38 .

The above-mentioned second damper mechanism 33 is set to be opposite to the indoor air suction part in the device body 6, between the position where the damper mechanism is set and the suction part of the above-mentioned processing side blower 24, the humidity control element 23 is bypassed and A bypass circuit 59 that guides room air to the direct-processing side blower 24 .

In the case of a normal humidification function, as shown by the solid line, the first damper mechanism 32 opens the air inlet body 22, and the second damper mechanism 33 closes the suction part of the room air to close the bypass circuit 59. Therefore, the outside air and the room air are guided along the paths as already explained above, and humidified.

When the ventilation mode is instructed as necessary, only the processing-side air blower 24 is continuously driven, and the regeneration-side air blower 25 is stopped. The heater 26 does not generate heat, and the geared motor 27 that is the rotational drive source of the humidity control element 23 stops.

And, as shown by the dotted line in the figure, the first damper mechanism 32 closes the air supply port body 22 to prevent the intake of outside air, and the second damper mechanism 33 opens the bypass circuit 59 so that the indoor suction part is directly communicated with the blower 24 on the processing side.

The room air is introduced into the device main body 6 from the suction port 4 without changing, but the room air is switched and guided to the bypass circuit 59 without being guided to the humidity control element 23 . The indoor air is guided to the processing-side blower 24 through the bypass circuit 59 , and then discharged to the outside from the exhaust port body 21 and the exhaust duct 43 .

Like this, in device main body 6, have the first damper mechanism 32 that opens and closes air supply port body 22 and this 1st damper mechanism is interlocked and make humidification function when air supply port body is opened, and in air supply The second damper mechanism 33 that switches to the ventilation function when the mouth body is closed.

Therefore, it is possible to obtain a ventilation function in which room air is directly discharged to the outside without taking in outside air. Since the air is only conducted to the humidity control element 23 during humidification, and is not conducted at all during ventilation, foreign matter does not adhere to the humidity control element 23 during ventilation, and its life can be extended.

In addition, the first damper mechanism 32 not only opens and closes the air supply port body 22 but also switches the operation and stop of the device main body 6 when switching between the humidification function and the ventilation function, that is, as the processing side blower 24 operates and The switching of the stop can also be performed to open and close the air supply port body 22 .

In this case, the air supply port body 22 is closed while the device main body 6 is stopped, so that external air does not flow into the device main body 6 . Therefore, outside air does not flow further to the humidity control element 23 during the stop, which contributes to the prolongation of its life.

Fig. 22A, Fig. 22B, Fig. 23A, Fig. 23B, Fig. 24A, Fig. 24B show the specific structure and function of the first damper mechanism 32 and the second damper mechanism 33, all omitting the stepper motor as the driving source.

The rotation shaft of the stepping motor 38 is connected to the drive shaft 32 b of the first damper mechanism 32 . The interlocking hole 33b of the second damper mechanism 33 is engaged with the interlocking pin 32d, and the second damper mechanism is rotationally displaced in conjunction with the rotational displacement of the first damper mechanism 32 .

23A and 23B illustrate the specific configuration and function of the first damper mechanism 32 . That is, on the base end portion of the air supply port body 22 protruding from the second device main body 50, a damper housing chamber 50a that is approximately semicircular in plan view is provided, and a semicircular housing chamber 50a is continuously provided on the center portion of the upper surface side of the housing chamber. The notch 50b.

The first damper mechanism 32 is accommodated in the damper housing chamber 50a, and the drive shaft 32b is engaged with the notch 50b and the pivot hole 32c with a bottom protrusion (not shown) to freely rotate as a fulcrum. The interlocking pin 32d protrudes from the upper surface of the damper housing chamber 50a, and when it rotates more than a predetermined amount, it locks at the end of the housing chamber to restrict the rotation.

FIG. 23A shows the state where the first damper mechanism 32 opens the air inlet body 22, which is the posture when the humidification function is performed or the processing side blower 24 is operating as described above.

FIG. 23B shows a state where the first damper mechanism 32 closes the air inlet body 22. Actually, the damper surface, which is the curved side surface of the opening and closing portion 32a, completely closes the base end opening of the air inlet body. At this time, it is a posture when switching to the ventilation function or when the processing side air blower 24 is stopped.

24A and 24B illustrate the specific configuration and function of the second damper mechanism 33 . That is, the first main case 31 constituting the first device body 26 is superimposed on the second device body 50 . The humidity control element assembly 23S is omitted and not shown for convenience of description.

The drive shaft 32b of the first damper mechanism 32 protrudes toward the support portion 35 of the first main housing 31, and the second damper mechanism 33 is supported by the support portion. In addition, the support portion 35 is provided with a curved guide slot for passing through the interlocking pin 32d of the first damper mechanism 32 and a curved guide groove for engaging the guide pin 33c of the second damper mechanism 33 (both are not shown). ).

Therefore, along with the rotational displacement of the first damper mechanism 32, the second damper mechanism 33 is rotationally displaced through the interlocking pin 32d and the interlocking hole 33b. At this time, the guide pin 33c of the second damper mechanism 33 is guided into the guide groove of the support portion 35, and the rotational posture of the second damper mechanism 33 is regulated.

Fig. 24A shows the state after the damper surface provided on the damper body 33a of the second damper mechanism 33 closes the opening for the bypass circuit provided on the first main casing 31, which is the case of making the humidification function as described above. . At this time, the first damper mechanism 32 opens the air inlet body 22 .

FIG. 24B shows the state where the second damper mechanism 33 opens the hole 59a for the bypass circuit, which is a ventilation in which the humidity control element 23 is bypassed and the indoor air in the suction device main body 6 is directly guided to the exhaust port body 21 side. function case. At this time, the first damper mechanism 32 closes the air inlet body 22 .

In this manner, switching between the humidification function and the ventilation function can be reliably performed by the first damper mechanism 32 and the second damper mechanism 33, thereby improving reliability. In fact, it is composed of multiple parts, but since they are integrated with each other, they can act like a single part to simplify the mechanism.

Furthermore, since a plurality of parts are driven by the stepping motor 38 as a single drive source, the degree of freedom in design increases, and the number of parts and cost can be reduced. The pressure loss can be reduced without forcing the flow path to bend, and the performance of the humidification function and the ventilation function can be improved.

As described above, according to the present invention, the components of the components are divided into units for each unit, and it is easy to cope with high performance, which is advantageous in cost reduction and the like.
