[0002]

2. Description of the Related Art As a humidifying device for adjusting a humidity environment, there is a humidifier that humidifies a small amount of water. In a typical humidifier, water is heated to evaporate, which is called a heating type. JP-B-60-34922 and JP-B-61-
A humidifier as disclosed in Japanese Patent No. 13542, a humidifier as disclosed in Japanese Utility Model Publication No. 60-647, which is called an ultrasonic type, which atomizes or atomizes water by ultrasonic vibration. Japanese Patent Publication No. 4-36316, which is called a natural evaporation type, which evaporates the water sucked up by a capillary action by ventilation.
There is a humidifier as disclosed in the publication.

Specifically, the heating type humidifier has a structure as shown in FIG. 20, for example. That is, the main body 1 is provided with a heating water tank 2 and a water receiving tank 5 that is connected to the heating water tank 2 via a pipe 3 and in which a water supply tank 4 is mounted. The water receiving tank 5 is provided with a rod portion 8 that pushes up the valve 7 built in the cap 6 of the water supply tank 4, and controls the flow of the replacement air depending on the position of the end of the cap and the water level of the water receiving tank 4. Then, the water in the water supply tank 4 is supplied to the heated water tank 2 at a constant water level. A heater, for example, a seed heater 9 is attached to the bottom of the heated water tank 2.

Utilizing the heat generated by the sheath heater 9, the water accumulated in the heating water tank 2 is heated and evaporated. Further, the heating type humidifier also has a structure in which, as shown in FIG. 21, a large amount of water supplied to the pot 10 is heated by a heater 11 installed on the peripheral wall of the pot 10 to be evaporated. Yes (pot type).

[0007]

However, such a humidifier also has many problems. That is, the heating-type humidifier has a sterilizing effect because the treated water is boiled by heating, but has a disadvantage due to the boiled treated water.

Specifically, (1) a large noise is generated when the treated water is boiled, that is, a remarkable noise is generated due to a phenomenon that steam is rapidly and abundantly discharged from the hot water to the atmosphere.

(2) Since the treated water stored in the heated water tank 2 is boiled, it takes a time from the start of heater energization to the generation of steam (time called start-up time). Means may have to be taken to preheat to reduce the time.

(3) The humidified air is preferably at a temperature that does not damage the environment, but the outlet temperature of the heating humidifier tends to be high. Especially, a small heating type humidifier has a strong tendency.

(4) Residual hardness components (scales) contained in the feed water, such as Ca and Mg, are deposited on the treated portion, and white smoke is generated due to the deposits, which causes humidified air. May be mixed and released.

(5) It can be seen that the residual hardness component scatters in the vicinity of the heated water tank 2 due to the vigorous motion of hot water. (6) Since the hot water is directly stored, if there is an accident such as a fall in the heating humidifier, the hot water may leak from the humidifier to the outside.

On the other hand, since the ultrasonic type humidifier does not have a structure for boiling treated water, there is no peculiar inconvenience of such a heating type humidifier, but since it does not have a sterilizing action, it is suitable for applications where hygiene is important. Is not suitable.

Further, recently, there is a tendency to attach great importance to hygiene, and the ultrasonic type humidifier has a problem that it cannot be coped with under such an environment unless a separate device for sterilization is provided.

On the other hand, the natural evaporation type humidifier (1) has a low humidification capacity. (2) Since the air is cooled by the latent heat of evaporation, the outlet temperature of the humidified air is unavoidably lowered, which may impair the environmental conditions.

(3) Residual hardness components (scales) contained in the feed water, such as Ca and Mg, are deposited in the fine pores, and the water absorption capacity is reduced early. The present invention was made in view of such circumstances,
Its purpose is to maintain the sterilizing effect of the heating type humidifier, while eliminating the problems of the heating type humidifier, ultrasonic humidifier, and natural evaporation type humidifier. To provide.

On the other hand, the heat of the heat source block heated to a high temperature by the heat source is transmitted to the heat conductor with which the water absorber is fitted, and the moisture absorbed by the water absorber is heated to bring it to a boil.

By this boiling, steam is generated from the water absorbing body. Then, this steam is directed to the steam outlet located above the upper space in the main body surrounded by the cover member. On the other hand, the outside air taken into the lower space of the main body by the operation of the blower reaches the end where the water tank is located along the U-shaped air passage,
From here, through the opening in the lateral partition plate and the inside of the ventilation member, it is blown out from the outlet of the ventilation member to the upper center of the upper space in the main body surrounded by the cover member.

The valve rod 52 is arranged at a position corresponding to the protrusion 47, and a receiving portion 56 for receiving the protrusion 47 is formed at the lower end. A valve body 57 that opens and closes the opening of the valve seat 55 is provided at the upper end portion.

With this configuration, the water supply tank 44
When mounted on the tank mounting portion 36, the valve element 57 is opened by pushing up the valve rod 52 by the protrusion 47, and the stored water is led out from the through hole 54 to the receiving tank portion 41. is there. At the same time, the water level at which the tank 42 has a constant amount of water,
That is, when the liquid surface reaches the tip of the ring wall 51 and reaches the position where the tip end opening is closed, the inflow of the replacement air is stopped (water sealing), and the water supply is stopped.

Further, in the water supply tank 44, when the water in the storage tank portion 42 is insufficient, the replacement air is introduced, and water is supplied from the inside so that a predetermined water amount (constant water level) is obtained. That is, outflow of the water supply in the water supply tank 44 is controlled according to the water level of the storage tank portion 42.

That is, the water supply tank 44 with a cap
Thus, a constant water amount supply means for maintaining a constant water amount in the storage tank portion 42 is configured. On the other hand, in the center of the annular storage tank 42,
A pedestal portion 58 as a water absorbing body supporting means is provided so as to close the hole 38 which is the inner cavity portion.

The pedestal portion 58 is made of a member having a high thermal conductivity, for example, an aluminum alloy having a high thermal conductivity, and has an inverted cup shape. The opening end of the pedestal portion 58 is fitted and fixed to the inner surface of the peripheral wall of the storage tank portion 42 via a heat insulating member 60 formed in an annular shape together with a flange portion 59 formed on the outer circumference of the opening end. is there. Further, the bottom wall of the pedestal portion 58 projects upward through the hole 38 surrounded by the peripheral wall 39.

On the surface of this pedestal part 58, the pedestal part 58
A water absorbing body 61 as a water absorbing means is placed so as to cover the above. That is, the water absorbent body 61 is made of, for example, a water absorbent member formed in a substantially inverted cup shape by matching a porous material with the outer surface shape of the pedestal portion 58.

The central portion of the water absorbent body 61 is fitted and inserted in the bottom side of the pedestal portion 58 and overlaps the entire bottom surface of the pedestal portion 58. The peripheral edge of the water absorbent body 61 extends to the vicinity of the bottom surface of the storage tank portion 42 while expanding. Thereby, the water absorbing body 61 is arranged so as to cover the entire surface of the pedestal portion 58.

The peripheral portion of the water absorbent body 61 is immersed in the water stored in the storage tank portion 42. Such water absorber 61
With the installation, the water absorber 61 sucks up (suctions) the water in the storage tank portion 42 from the peripheral edge toward the center by the capillary action.

A small-diameter hole portion 62 is provided in a part of the water absorbent body 61, for example, in the central portion of the wall portion 61a overlapping the upper surface of the pedestal portion 61. Thereby, the water absorbing body 61 and the pedestal portion 58
The fluid filled between and is allowed to escape to the outside.

A handle, for example, a U-shaped handle 63 is provided at the center of the wall portion 61a of the water absorbent body 61. As a result, as shown in FIG. 3, the handle 63 can be used to remove or attach the water absorbing body 61 from the pedestal portion 58.

On the inner surface of the peripheral wall portion of the pedestal portion 58 on which the water absorbing body 61 overlaps, an electric heater (energizing heater) as a heating means, for example, a planar band heater composed of a PTC heater. 64 are provided along the circumferential direction.

As a result, the water absorbing body 61 becomes a band heater.
The heater 64 is used as a heat source, and the pedestal portion 58 is used as a heat transfer surface for heating. That is, the water absorbed by the water absorber 61 is evaporated by heating.

Here, the PTC heater has the characteristic that the resistance value rapidly increases at a certain temperature, making it difficult for current to flow and reducing the amount of heat generation.
The self-controllability of the energizing current of the controller allows it to maintain a constant temperature without overheating.

On the other hand, on the left side wall of the main body case 31 below the tank mounting portion 36, an air inlet 65 constituting a blower mechanism 68 is provided. The cover 32 is also provided with a steam outlet 66. The steam outlet 66 is centered on, for example, a cover portion immediately above the enclosure member 34,
It is formed from a large-diameter opening that spreads in the front, rear, left, and right directions.

As a result, inside the main body 30, there is a space extending in the left-right direction of the main body case 31 below the lateral partition member 33 and the right side inside the main body case 31 communicating with this space. The air passage 67 is formed by the air passage space existing in

At the site on the air inlet side of the air supply passage 67,
A blower, for example, a crossflow fan 69 directly connected to the motor is installed. As a result, the air outside the main body 30 is discharged from the air inlet 6
7a is taken into the inside, and is directed to the steam outlet 66 for air supply.

A steam path 70 is provided in the main body 30. The vapor path 70 is configured by using the evaporation chamber 37 as it is, and the inlet 7 is provided in the portion of the water absorber 61 where the vapor is generated.
0a is facing. The outlet 70b of the steam path 70 communicates with the defective portion above the surrounding member 34. That is,
The outlet 70b is open to the air supply path 67.

With the blower mechanism 68 thus constructed,
The vapor evaporated from the water absorbing body 65 is sucked by the air flow in the air supply passage 67, mixed with the air, and discharged from the vapor outlet 66 to the outside.

On the other hand, a control system is built in the body case 31. FIG. 5 shows the configuration of this control system. That is, the control system is, for example, a micro computer.
The control unit 71 is composed of a computer. This control unit 7
A humidity setting unit 72 for setting the humidity, which is provided on the outer surface of the main body case 31, is connected to the unit 1. A humidity detector 73 for detecting humidity, which is provided near the air inlet 65, is connected to the control unit 71.

A band heater 64 and a cross flow fan 69 are connected to the control unit 71. The control unit 71 uses the band heater 64 and the cross flow fan based on the set humidity set by the humidity setting unit 72 and the humidity detected by the humidity detector 73, for example, according to the difference between the set humidity and the detected humidity. 6
The function of controlling the energization of 9 on / off is set. As a result, the humidifier is operated (operated) only when there is a request for humidification.

A fuse 74 is provided on the inner surface of the pedestal portion 58 adjacent to the band heater 64. The fuse 74 is interposed in the power supply circuit of the control system and prevents an overcurrent from flowing.

Next, the operation of the humidifier thus constructed will be described. First, the cartridge type water supply tank 44 placed upside down fills the receiving tank portion 41 and the storage tank portion 42 with a constant amount of water.

That is, the water supply tank 44 is supplied into the receiving tank portion 41 while the water enclosed inside is replaced with the outside air according to the opening operation of the opening / closing valve 48 by the protrusion 47. This water supply is continued until the inside of the storage tank portion 42 reaches a constant amount of water, that is, a constant water level.

When the water level reaches a certain level, the front end opening of the ring wall 51 of the water supply cap 45 is closed by the liquid surface, and the inflow of replacement air is stopped (water seal). That is, the outflow of water from the water supply tank 44 is stopped, and the receiving tank portion 41 and the storage tank portion 42 are filled with a constant amount of water.

Further, the water absorbing body 61 sucks up the water in the storage tank portion 42 toward the center side at a predetermined speed based on the capillary action from the peripheral edge portion (suction). In addition, when the water level in the storage tank portion 42 is lowered by suction of the suction body 61, the front end opening of the ring wall 51 closed by the liquid surface is opened, and the water is received from the water supply tank 44 until the water level reaches a constant level again. Water is supplied to the portion 41.

From this state, the humidifier is powered on in an environment where humidification is required, for example, in a room. As a result, the band heater 64 and the cross-flow fan 6
9 is energized.

Then, the band heater 64 generates heat. This heat is transmitted to the water absorbing body 61 mounted on the pedestal portion 58 through the pedestal portion 58, and heats the water absorbing body 61. As a result, the water in the capillaries of the water absorbent body 61 that has absorbed water over a wide area is heated and boiled, and is evaporated and vaporized from the water supply body 61.

At this time, since the air is not excessively heated, the rise in the outlet temperature of the humidified air due to this is suppressed. On the other hand, the humidifier takes in indoor air from the air inlet 65 into the main body 30 by operating the cross flow fan 69. This air is blown out from the steam outlet 66 through the air supply passage 67.

Here, in the steam path 67, the air supply path 67
Negative pressure is generated by the ejector action caused by the air flow flowing through. Due to this negative pressure, the vapor evaporated from the water absorber 61 is sucked out toward the air supply passage 67.

When the steam reaches the air supply passage 67, it is introduced into the steam outlet 66 while being mixed with the air (low temperature air) in the air supply passage 67 successively. As a result, the humidified air is discharged to the outside of the main body 30 from the steam outlet 66 after being lowered to a low outlet temperature that does not damage the environment.

Such an ON operation continues until the humidity detector 73 detects a predetermined humidity value. Then, when the detected humidity reaches the predetermined humidity value, the operation of the band heater 64 and the cross flow fan 69 is turned off by the command of the control unit 71.

By repeating the on / off operation of the humidifier, the room is maintained at a comfortable humidity. Since such a humidifier is configured to heat and boil fine water in a capillary tube, the conventional heating type humidifier, ultrasonic humidifier, and natural evaporation type can be used while maintaining the sterilization effect of the conventional heating type humidifier. It is possible to obtain a high-performance humidifier that solves the problems of the humidifier.

That is, the water supply type heating type humidifier is as follows. Since the sterilizing effect of heating is maintained, no extra equipment for sterilization is required.

B. Since the "phenomenon in which a large amount of steam is rapidly released from hot water into the atmosphere during the boiling process" is significantly mitigated (suppressed), the noise caused by boiling is extremely small.
It becomes a quiet humidifier.

C. The minute water in a capillary tube is heated and boiled, so the time it takes to generate steam (rise time)
Can be short. d. The generated steam is discharged to the outside of the main body 30 while being mixed with the air supply, so that the outlet temperature of the humidified air becomes an appropriate temperature.

E. At the time of heating and boiling, hot water does not scatter in the vicinity of the storage tank portion 42, so white smoke is not generated unlike the conventional heating type, and it is hygienic. f. Since hot water is not stored directly, leakage of hot water caused by the overturning of the humidifier, which occurs in the conventional heating system, can be avoided.

G. Since the fine water in the capillaries is heated and boiled, the humidifying ability is high. h. The decrease in the water absorption capacity of the water absorbent body 61 due to the residual hardness component (scale) can be remarkably alleviated.

That is, when moisture evaporates from the water absorbing body 61, a residual hardness component (scale) is deposited on the water absorbing body 61 as a residue of evaporation, but in evaporation performed by heating and boiling the water in the capillary tube. The process of gradually accumulating the residual hardness component and the evaporation process simultaneously proceed.

This means that since the residual hardness component is formed while ensuring the vapor passage, unlike the conventional natural evaporation type humidifier, the decrease in the water absorbing capacity of the water absorbing body 61 is remarkably alleviated. The life of the water absorber 61 is long.

The following effects are achieved. Moreover, in addition to these effects, the humidifier is: i. As the water absorbing structure, the water absorbing body 6 supported by the pedestal portion 58 from the peripheral edge portion of the water absorbing body 61 by using the annular storage tank portion 42.
By using the configuration in which water is sucked up to the center of 1, it is possible to absorb and evaporate water from the storage tank 42 in a wide area, and the water absorbent body 61 can have a high water absorbing capacity.

J. By controlling the heating operation and the blowing operation according to the difference between the set humidity and the humidity outside the main body 30, the humidity in the environment such as the room can be always kept at a comfortable humidity.

K. As the structure of the blower mechanism 68, the air passage 6
By using the configuration in which the vapor flowing from the water absorber 61 is sucked through the vapor path 70 by the air flow flowing through 7,
The steam from the water absorbing body 61 comes into contact with the air supplied from the outside of the main body and efficiently mixes.

As a result, even if the humidifier is downsized and the vaporization portion and the vaporization outlet 66 are arranged close to each other, no additional equipment is required.
The outlet temperature of the humidified air can be set to an appropriate temperature.
According to the experiment, the outlet temperature of the humidified air was as low as about 60 ° C.

L. The inverted cup-shaped pedestal portion 58 is used, and the open end of the pedestal portion 58 is connected to the storage tank portion 4 via the heat insulating member 60.
By adopting the configuration fixed to 2, it is possible to secure a wide evaporation area and prevent heat from escaping from the pedestal portion 58.

As a result, the evaporation capacity of the water absorbing body 61 can be improved. In addition to this, by adopting a configuration in which the band heater 64 is provided on the inner surface of the peripheral wall portion of the pedestal portion 58, the heat capacity can be small, and accordingly, humidified air can be generated promptly without requiring preheating. It is possible to do so, and it is excellent in energy saving.

Furthermore, since it is not necessary to evaporate extra water,
Since the band heater 64 has a minimum capacity and prevents the air from being excessively heated, it contributes to the suppression of the rise in the outlet temperature of the humidified air.

Further, by adopting the pedestal portion 58 made of an aluminum alloy having a high thermal conductivity, the heat conduction of the pedestal portion 58 is utilized to efficiently heat the moisture absorbed by the water absorbing body 61 without waste. You can

In addition, by adopting the PTC heater, the heat generation temperature can be kept constant by the self-controlling property that the resistance value rapidly increases at a certain temperature and the heat generation amount decreases. Therefore, it is possible to obtain a predetermined performance with a simple configuration.

M. By providing the hole portion 62 in the water absorbent body 61, it is possible to escape the vapor, which has no place to go, generated between the water absorbent body 61 and the pedestal portion 58 to the outside. That is, when the water content in the capillaries evaporates by heating, the vapor generated near the interface of the pedestal portion 58 in the water absorbent body 61 rises up in the interface and loses its place, causing the water absorbent body 61 to swell and lose its shape. There is.

It is assumed that the interface is closed by the vapor film. The presence of the hole 62 keeps the interface open, so that such a closed state does not occur.

The following effects are achieved. 6 and 7
Shows a second embodiment of the present invention. This embodiment is different from the first embodiment in that a coil-shaped electric heater (current-carrying heater) 80 is adopted instead of the band heater.
The difference is that the connector 80 is screwed and fixed to the inner surface of the peripheral wall of the pedestal portion 58, like the relationship between the male screw and the female screw.

That is, the electric heater 80 includes the pedestal portion 58.
It has a coil shape according to the peripheral wall diameter. Also the pedestal part 5
A coil-shaped recess 81 for receiving the electric heater 80 is formed on the inner surface of the peripheral wall of the coil 8.

As a result, as shown in FIG.
By screwing the electric heater 80 into the screw 1, the electric heaters 80 become threaded surfaces, and the electric heater 80 is attached to the peripheral wall of the pedestal portion 58.

With such a structure, it is possible to easily attach the electric heater 80 to the pedestal portion 58 by utilizing the electric heater 80 itself without requiring a separate fixing means. Moreover, since the electric heater 80 and the pedestal portion 58 are in contact with each other over a wide contact area, it is possible to heat the absorbed water by effectively utilizing the heat of the electric heater 80.

8 and 9 show a third embodiment of the present invention. This embodiment is different from the first embodiment in that the water absorbent body 6
1 is different in the configuration. That is, the water absorbent body 6 of this embodiment
1 includes a water absorbing member 90 (water absorbing member) formed by, for example, forming a porous material in accordance with the outer surface shape of the pedestal portion 58, and a reinforcing member 91 having a handle 63 for detaching and attaching the water absorbing body 61. It is configured in combination.

More specifically, the reinforcing member 91 is, for example, as shown in FIG.
As shown in FIG. 9A, a bottomed cylindrical shape corresponding to the surface shape of the pedestal portion 58 from the mesh member 92, or, for example, FIG.
As shown in (b), the thin wire member 93 is formed into a bottomed cylindrical basket-like shape corresponding to the surface shape of the pedestal portion 58. When making the reinforcing member 91, a handle 63 is also provided.

The water absorbent body 61 is constructed, for example, by arranging a reinforcing member 91 on the outer surface of the water absorbent body 61 and adhering it with an adhesive or the like to integrate them. Thereby, the water absorber 6
1 is provided with the rigidity necessary to operate the water absorbing body 61 for removal, and the removal operation using the handle 63 becomes easy.

That is, the water absorber 61 may be replaced from the viewpoint of maintenance. The water absorbent body 61 in which the reinforcing member 91 which also serves as the handle 63 is integrated has a higher rigidity and thus is easier to use. Therefore, in the first embodiment, the replacement work as shown in FIG. This makes it easy to place and remove the pedestal 58.

Moreover, the reinforcing member 91 also serves as a guide for determining the replacement time of the water absorbing body 61. That is, whether or not the residual hardness component (scale) has developed to the extent that it covers the reinforcing member 91 is a criterion for determining the replacement time of the water absorbing body 61. This is convenient because the reinforcing member 91 also serves as a life measuring means for the water absorbent body 61.

FIG. 10 shows a fourth embodiment of the present invention.
The present embodiment is different from the first embodiment in the shape of the water absorbing body 61. That is, in the water absorbent body 61 of the present embodiment, the thickness dimension t of the water absorbent body 61 is gradually thinned from the edge portion immersed in the storage tank portion 42 toward the central portion overlapping the upper portion of the pedestal portion 58. That is, the water absorbent body 61 has a large cross-sectional area on the water absorption side and a small cross-sectional area at the portion where evaporation is performed.

As a result, the water absorbent body 61 can be made compact and have high performance. That is, the water absorbing body 61 sucks up from the edge portion and evaporates toward the central portion,
During the process, the amount of water passing through is reduced due to evaporation.

Therefore, by changing the thickness of the water absorbing body 61 as described above, the water absorbing body 61 can maintain a high water absorbing performance and a high evaporation performance while being small in size. FIG. 11 shows a fifth embodiment of the present invention.

This embodiment is different from the first embodiment in that the pedestal portion 6
1 is different from the heater mounting structure. That is, the pedestal portion 61 of the present embodiment has a dish shape in which the open end is fixed to the storage tank portion 42 via the heat insulating member 60 and the bottom wall is recessed in the inner cavity portion at the center of the storage tank portion. Of course, also in this case, as in the first embodiment, the pedestal portion 58 is formed of an aluminum alloy having high thermal conductivity.

On the back surface of the bottom wall of the dish-shaped pedestal portion 61, a spiral electric heater 100 (energization heater) is provided. In addition, the surface of the pedestal portion 61 in contact with the electric heater 100,
That is, a spiral recessed portion 101 and a coiled recessed portion 102 that fit into the surface shape of the electric heater 100 are formed on the back surface and the inner peripheral surface, and the electric heater 100 and the pedestal portion 6 are formed.
1 is contacted with a wide contact area.

In addition to the effect described in the first embodiment, such a humidifier can absorb water from the storage tank portion 42 at a low lift by adopting the pedestal portion 61 in the shape of a shallow plate.
The effect of being able to enhance the evaporation ability of

Further, similar to the first embodiment, since the heat capacity is small, preheating is not required and the humidified air can be promptly generated by using the electric heater 100 on the back surface. It is possible.

In addition, the electric heater 100 and the pedestal portion 58 are attached to each other in a structure in which their respective attachment surfaces are matched with each other's shape so that they are in contact with each other over a wide contact area. Water absorption can be performed by effectively utilizing the heat of the electric heater 100.

Of course, the water absorbent body 61 of the present embodiment has a structure in which the reinforcing member is reinforced as in the third embodiment, but the thickness t is changed as in the fourth embodiment. Good.

FIG. 12 shows a sixth embodiment of the present invention.
This embodiment is a modification of the fifth embodiment, and instead of the spiral electric heater, a flat electric heater is provided on the back surface of the pedestal portion 61.

In the water tank 205, a heat source block 303 is fitted on the inner wall 206 so as to close the hole 209. For specific attachment, for example, the tip of the inner wall 206 may be a shaft that is narrowed inward, and the lower end of the heat source block 303 may be fitted and fitted so as to abut the step of this narrowed portion, and the two may be joined together. Has been done. With this joint structure, the size is reduced.

The heat source block 303 is formed by forming a frustoconical block from a member having a high thermal conductivity, for example, an Al (aluminum) alloy member, and casting a heat source 304 such as a sheath heater in the block. The heat generated from the heat source 304 is efficiently transferred to the entire block.

Particularly, the heat source block 303 and the heat conductor 305
In order to achieve a tight fit at the time of operation of the humidifier due to the difference in thermal expansion, for example, the heat source located inside is selected from Al alloy and the heat receiving side located outside is selected from copper alloy. High heat transfer performance is obtained at the time of operation.

Of course, the heat source block 303, the heat conductor 3
It is needless to say that Al alloy and copper alloy may be used for both No. 05 and No. 05 because they are materials having good thermal conductivity.

The lower portion of the heat conductor 305 is a cylindrical portion 306. A heat insulating skirt portion 307 made of a heat insulating member is fitted on the outer side of the cylindrical portion 306 to form a heating rotating surface on the upper part and an insulating rotating surface on the lower part. There is. And this skirt part 307
Has a lower end extending into the water tank 205.

On the entire conical surface of the heat conductor 305 protruding into the upper space, the water absorber 400 is attached so as to be in close contact with the same surface. Specifically, as shown in FIG. 18, the water absorbent body 400 has a fan-shaped expanded shape, and a pair of ears 402, 402 having a pin hole 401 is projected at each end on the smaller diameter side. A flat plate-shaped water absorbing material is used. Then, this water absorbing material is wrapped around the conical surface of the heat conductor 305, and the ears 402, 402 are clipped by the clip 403.
By stopping each other, one surface of the water absorbing material is brought into close contact with the outer surface of the conical portion 308 of the heat conductor 305.

The clip 403 has a folding arm 404 as a main body, and a pin 40 is provided on one side of the arm 404.

A structure that is designed to be exposed to the outside of 201 is used.

Specifically, as shown in FIGS. 13 and 16, in the joint 407, a bridge member 409 is formed at the head opening of the heat conductor 305 so as to traverse the opening, for example, a band-shaped plate. Attached to the heat conductor 305 of the bridge member 407.
For example, a structure in which a cylindrical boss portion 410 having an internal thread engraved on its inner surface is provided in a central portion corresponding to the central portion of the above is used.

Further, for the handle 408, for example, a T-shaped member is adopted, and an operating portion 411 for rotating operation is used.
The structure in which a and the insertion portion 411b with respect to the boss portion 410 are configured, and the screw portion 412 that can be screwed into the boss portion 410 is provided on the base side of the insertion portion 411.

Accordingly, by inserting the insertion portion 411b from the upper side of the heat conductor 305 into the boss portion 410, engaging the screws with each other, and advancing the tip end of the insertion portion 411b, the insertion portion 411b becomes a heat source block. By pushing up the heat conductor 305 by hitting it against the upper surface of the heat conductor 303, the heat conductor 305 that has been tightly fitted is forcibly released from the heat source block 303. Then, the heat conductor 305 is taken out of the main body 201, and the heat conductor 305
It is designed so that the water absorbing body 400 wound around is replaced. However, in the present embodiment, the insertion portion 4 that abuts

The tip portion of the insertion portion 411b is made of, for example, a plastic material, and has a structure in which the heat source block 303 is not damaged even if the insertion portion 411b contacts the heat source block 303. .

The outer surface of the heat conductor 305, particularly the outer surface in contact with the water absorber 400, is plated with chrome (Cr) to prevent the water absorber 400 from sticking due to the residual hardness component (scale). The water absorption body 400 is prevented from sticking due to the hardness component (scale) so that the water absorption body 400 can be easily replaced.

Inner wall 2 of heat source block 303 and water tank 205
As shown in FIG. 16, a heat adiabatic packing 309 is interposed on the mating surface with 06. This packing 30
9, the heat of the heat source block 303 is prevented from escaping to the water tank 205.

The pressing rod 312 has such a length that it presses the heat conductor 305 when the cover member 300 is installed on the partition member 204, and the heat conductor 305 is pressed against the heat source block 303 from above. is there.

The base end portion of the pressing rod 312 projects from the inside of the top portion 313 of the cover member 300 via the coil spring 314 as shown in FIG.
It is elastically supported by 15 so as to be displaceable in the axial direction, and the spring force of the coil spring 314 prevents the heat conductor 305 from being blown up by steam (due to the airtight action of the lip 310). Needless to say, the thrust can be adjusted by the structure provided with the coil spring 314.

On the other hand, in the lower space of the main body 201, an air supply passage 216 is formed as shown in FIG. Explaining the structure of the air supply passage 216, 217 is the water tank 2.

The wall portion 218 has, for example, a circular vent hole 2
19 are perforated and divided into two spaces 220,
221 is connected. Also, on the right wall of the main body 201,
An intake hole 222 communicating with the front space 220 partitioned by the lower space is provided.

Further, of the four corners surrounded by the cover member 300 in the partition member 204, for example, a region adjacent to the water tank 205, which is two diagonal positions sandwiching an extension line extending the water supply passage 214, is partitioned by a lower space. Rear space 221
A ventilation hole 223 (opening) in the shape of a triangle, for example, which follows a corner is provided to communicate between the space surrounded by the cover member 330 and the air intake hole 22 in the lower space of the main body 201.
An air supply passage 216 having a U-shape as a whole is formed by using 2 as a tip portion and a vent hole 223 as an end portion.

With this structure, the water tank 205 in which heat-bearing parts such as the heat source block 301 are arranged is arranged at the end side, and the air supply passage 216 in which the tank receiving portion 211 having no thermal influence is arranged on the way is constructed. There is.

Further, in the wall portion 218, the fan 224 is arranged on the side of the space 221 with the ventilation hole 219 interposed therebetween, and the space 22
A blower 226 having a fan motor 225 coaxially connected to the fan 224 is installed on the second side. Due to the operation of the blower 226, the intake port 222
The outside air is circulated through the air supply passage 216. Reference numeral 228 indicates a shroud provided around the fan 224.

On the wall surface forming the front space 220 on the upstream side of the air supply passage 216, a control board 227 mounting various electronic parts constituting a control circuit of a humidifier, an electric device (not shown), etc. The components are installed so that the outside air flowing through the air supply passage 216 can be used for cooling.

A ventilation member 229 is provided on the upper surface portion of the partition member 204 where the ventilation hole 223 is present, and the projection member 229 projects upward from the portion along the inner surface of the side wall of the cover member 300.

The ventilation member 229 has, for example, a triangular shape whose outer shape follows the corners, and has a hollow portion 230 whose upper end is closed. The upper end of this hollow portion 230 is the cover member 3.
00 to the upper portion (the inner surface of the top portion 313). Further, an air outlet 231 communicating with the vent hole 223 through the inside of the hollow portion 230 is provided in an upper slope portion of the hollow portion 230 facing the center of the space surrounded by the cover member 300, and the blower 236 removes the air outlet 231. The introduced outside air can be blown out from the air outlet 231 toward the center of the cover member 300 where the steam outlet 302 is located.

Further, the ventilation member 229 not only blows out air but also protrudes upward along the inner surface of the cover member 330, so that when the cover member 330 is placed at a predetermined position of the partition member 204. The structure also serves as a guide and a positioning member.

More specifically, the cover member 330 has an inverted box shape with a rectangular cross section having a cross-sectional area large enough to contain both the ventilation member 229 and the water tank 205. Then, the cover member 330 is divided into the partition member 2
The cover member 330 can be attached at a predetermined position only by placing the cover member 330 on 04.

Although the ventilation holes 223 and the ventilation member 229 are provided at diagonal positions respectively, the ventilation holes 223 and the ventilation member 229 are provided at at least one of the two diagonal positions.
May be provided.

Further, the water supply tank 210 includes the cover member 30.
The remaining space in the main body 201 which avoids 0 is filled up, and it is configured in a substantially L-shape with one side being thin in a horizontal cross section, and a storage volume as large as possible is obtained.

The water tank 205 is provided with a sub water tank 232 which is located near the front wall of the main body 201 and is connected to the water tank 205, and which is made of, for example, a transparent member, and faces the sub water tank 232. A window portion 233 is provided on the front side wall portion of the main body 201, and the water surface position of the water tank 205 is visible through the window portion 233 and the sub water tank 232. Of course, at this water surface position, a means for detecting the water level may be installed in the sub water tank 232, and this may be made visible through the window 233.

Next, the operation of the humidifier thus constructed will be described. As shown in FIG. 16, the water supply tank 210, the heat conductor 305, the water absorber 400, the cover member 300, etc. are mounted in the main body 201, and then the power of the humidifier placed in the room is turned on.

Then, the heat source 304 such as a sheathed heater and the blower 226 are energized by a command from the control circuit. As a result, the heat source 304 generates heat, and this heat heats the entire heat source block 303. The heat of the heat source block 303 is transmitted to the heat conductor 305.

Here, the heat source block 303 and the heat conductor 3
No. 05 is a tight fit due to the difference in thermal expansion and is in close contact with each other, so that the heat from the heat source block 303 is dispersed to the wide outer surface of the heat conductor 305.

As a result, the heat from the heat source block 303 is efficiently transferred to the heat conductor 305. This is because the packing 309 with the lip 310 prevents heat from escaping from the heat source block 303 to the water tank 205 unnecessarily.

The heat transferred to the heat conductor 305 causes the water absorber 400 wound around the heat conductor 305.
Is heated. At this time, in the water tank 205, water from which components such as calcium ions Ca ⁻ , magnesium ions Mg ⁻ , sodium ions Na ^−, etc., which cause generation of residual hardness components (scales) are removed by the adsorption action of the active biloc 215. The water absorbing body 400 absorbs the moisture excluding the component that causes the generation of the residual hardness component by a capillary phenomenon.

As a result, the water in the capillaries of the water absorbent body 400 is heated and boiled, and is evaporated and vaporized from the water absorbent body 400. At this time, the skirt portion 307 below the heat conductor 305
Is heat-insulating, the heat-insulating effect does not cause inadvertent boiling in the lower part of the water absorber 400 or careless heating of the water in the water tank 205.

The heat conductor 305 is always pressed by the pressing rod 312 protruding from the top of the cover member 300 from above with the spring force of the coil spring 314. Even if it receives the force of steam filling the space between the wall of 305 and the heat source block 303, it does not escape. That is, the heating block 30
3 does not occur on the contact surface between the heat conductor 3 and the heat conductor 305.

On the other hand, the humidifier takes in the indoor air from the intake port 222 to the air supply passage 216 by operating the blower 226. This air is the lower space of the main body 201,
That is, it reaches the opening 223 while curving in a U shape following the air supply passage 216. During this time, in the electronic device such as the control board 227, the outside air flowing through the air supply passage 216 is cooled as cooling air.

This air is blown from the air outlet 231 into the space surrounded by the cover member 300 through the ventilation member 229. Then, in the center of the cover member 300, the blown air is blown to the outside through the steam outlet 302 and the steam port 203 while being mixed with the steam evaporated from the water absorber 400.

As a result, the humidified air is blown to the outside after it has been cooled to a low outlet temperature. During this humidifying operation, the water absorber 400 tries to adhere to the heat conductor 305 due to the residual hardness component (scale).
Since the outer surface of 05 is preliminarily plated with chrome (which is hard to adhere to the residual hardness component), such adhesion does not occur.

[0213] Similar to the first embodiment, such an ON operation is continued until a predetermined humidity value is reached, and when the predetermined humidity is reached,
Shut off the humidifier. That is, by repeating the on / off operation of the humidifier, the indoor humidity is maintained at a comfortable level.

As a result, as in the case of the first embodiment, it is possible to realize a humidifier of a small water content and a high water absorption capacity. Moreover, since the components such as calcium ion Ca ⁻ , magnesium ion Mg ⁻ , and sodium ion Na ⁻ in the feed water have been removed in advance by the adsorption action of the activated carbon bilock 215,
The generation of residual hardness components due to the same ions is minimized.

When replacing the used water absorbing body 400, the power is first turned off. Then, the lid member 202
Is removed to open the upper portion of the main body 201, and then the cover member 300 is taken out from the inside of the main body 201 using the grip portion 316 attached to the upper side thereof to expose the head of the heat conductor 305.

After that, using the handle 408, as shown in FIG.
The heat conductor 305 that is tightly fitted as shown in FIG. For this, the insertion portion 411b of the handle 408 is attached to the boss portion 4 of the heat conductor 305.
10 and then the operation portion 411a of the handle 408.
It suffices to rotate in the direction of screwing in.

That is, when the insertion portion 411 moves forward in accordance with the engagement between the male screw portion 412 and the female screw, first, the hole portion 413 at the tip portion is inserted into the protrusion 414 at the head portion of the heat source block 303. Then, the tip of the insertion portion 411b touches the upper surface of the heat source block 303,
The upper surface is pressed.

Here, the heat source block 303 is fixed,
Since the heat conductor 305 is fitted, when the tip of the insertion portion 411b comes into contact with the heat source block 303, the heat conductor 305 is detached from the heat source block 303 by being screwed. To be done.

At this time, since both the heat source block 303 and the heat conductor 305 are released from the interference fit (because the power is off and the temperature has dropped), the heat conductor 305.
Are easily removed from the heat source block 303.

After the removal of the heat conductor 305, the heat conductor 305 with the water absorbing body 400 is carried out of the main body 210 by holding the handle 408. Then, at a predetermined place, the clip 403 is removed, and the used water absorber 400 is removed from the heat conductor 305.

At this time, the water absorber 400 is the heat conductor 30.
Since the chrome plating applied to the outer surface of No. 5 prevents sticking to the heat conductor 305 due to the residual hardness component, it can be easily removed from the heat conductor 305.

Once removed, the new water absorber 400 is wrapped around the heat conductor 305 and secured with the clip 403.
Replace the water absorber 400. Then, for example, handle 40
8, the heat conductor 305 is removed, and the heat conductor 305 is fitted into the head of the heat source block 303 while gripping the water absorbent body 400 by hand.

Next, the cover member 300 is placed on the partition member 204 using the ventilation member 229 as a guide so as to surround the heat conductor 305, and the top portion 313 is fixed to the upper end of the ventilation member 229, for example, screwed. For example, the pressing rod 312 protruding from the inside of the top of the cover member 300 presses the bridge member 409 at the head of the heat conductor 305 from the upper side to securely tighten the heat conductor 305. Of course,
This tightening also depends on the spring force of the coil spring 314.

Then, if the lid member 202 is attached to the upper opening of the main body 201, the replacement of the water absorbing body 400 can be easily completed by using the handle 408. Even with such a humidifier, as in the case of the first embodiment, a high-performance humidifier that eliminates the conventional problems can be obtained.

Moreover, since the steam is generated only in the space surrounded by the cover member 300 and partitioned, the steam does not affect each part of the main body 201.

In addition, since the device for accommodating heat is arranged at the end and the tank receiving portion 211 and the blower 226 are arranged in the middle, the air supply ventilation 216 is used, so that the heat that heats the water absorbing body 400 affects the surroundings. Blower 2 not to give
26 provides high cooling performance.

Since the ventilation member 229 is used as it is as a positioning member to mount the cover member 300, a separate mounting structure is unnecessary. In addition, the water supply tank 210 has a main body 201 that avoids the cover member 300, which is a space necessary for replacing the water absorbing body 400.
In order to fill the remaining space of the main body 201, a horizontal section has a thin L-shaped shape on one side.
It is possible to provide the humidifier having the water supply tank 210 that occupies the inner space as effectively as possible to increase the volume. Although activated carbon bilock 215 was used as the adsorbent, other adsorbents may be used to remove the components that cause the generation of the residual hardness component.
