[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electronic dehumidifier suitable for dehumidifying the inside of a push-in room or the like.

[0002]

[Prior Art]

 Traditionally, most households have not been equipped with dehumidification inside the closet.In the rainy season and winter, moisture in the air inside the closet condenses on the walls, causing molds to build up in the closet. There was a problem such as letting it.

On the other hand, in a conventional dehumidifier for dehumidifying the inside of a house, air is compressed by a compressor, the compressed air is adiabatically expanded and cooled, and moisture in the air is condensed on the cooling surface for dehumidification. However, it has the drawbacks of large electric capacity, large volume and weight, and noise.

[0004]

[Problems to be solved by the device]

 As a dehumidifier that keeps a limited space such as a closet, a storage room, a closet, etc. where household items such as futons and clothes that should avoid high humidity are kept at an appropriate humidity, features such as quietness, compactness, and no maintenance are required. Is. As a dehumidifier equipped with these features, a dehumidifier that applies a thermoelectric module has been recently announced, but the dehumidifiers that have been provided up until now require the constant removal of dehumidified water. However, if the condensate is not discarded, the water will become full and will automatically stop and not perform dehumidification.

An object of the present invention is to provide an electronic dehumidifier to which a thermoelectric module is applied, which can treat water generated by dehumidification without requiring human labor.

[0006]

[Means for Solving the Problems]

 The structure of the electronic dehumidifier of the present invention is such that the inside of the dehumidifier is partitioned by a partition wall into a dehumidifying chamber and an evaporating chamber, and the dehumidifying chamber is fixed on both sides of the intake port, the exhaust port, the thermoelectric module, and the thermoelectric module. A cooling body and a heat radiating body are provided, and a water absorbing body that absorbs condensed water generated by condensation of moisture in the air that is in contact with the cooling body is provided. The cooling chamber is configured to be dehumidified and then discharged from the exhaust port, and the evaporation chamber is provided with an exhaust port and an exhaust fan for discharging the air in the evaporation chamber to the outside from the exhaust port. The water absorbing body in the dehumidifying chamber extends into the evaporation chamber through the opening provided in the partition wall.

In the above, the partition wall may be configured so that the radiator also serves as the partition wall.

[0008]

[Action]

 The electronic dehumidifier is attached to a wall such as a closet so that the exhaust port of the evaporation chamber faces the opening provided in the wall. The operation of this electronic dehumidifier will be described below.

When the thermoelectric module and the fan are energized, the air in the space to be dehumidified, such as a push-in, flows into the dehumidification chamber from the intake port and the air flows to the cooling body.

On the other hand, the cooling body is cooled by the thermoelectric module, and the surface temperature of the cooling body becomes low and drops to the dew point temperature. Therefore, the air in contact with the cooling body is cooled by the cooling body and the surface of the cooling body is cooled. Condensation of water in the air.

The air dehumidified by the cooling body is returned from the exhaust port into the dehumidified space such as a push-in chamber.

On the other hand, the condensed water is absorbed by the water absorbing body and moves through the water absorbing body to the water absorbing body arranged on the evaporation chamber side. The exhaust fan in the evaporation chamber discharges the air in the evaporation chamber to the outside, but since there is no air inlet in the evaporation chamber, the pressure inside the evaporation chamber becomes lower than that in the other chambers, promoting the evaporation of water in the water absorption body. To be done. The water evaporated in the evaporation chamber is discharged to the outside by the exhaust fan.

In this way, the water in the air in the space to be dehumidified such as a push-in chamber once becomes condensed water, but evaporates in the evaporation chamber and moves to the outside.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, the interior of the electronic dehumidifier 1 is divided by a partition wall 2 provided in the vertical direction into a dehumidification chamber 3 and an evaporation chamber 4 arranged adjacent to the dehumidification chamber 3 and air between them is separated. Very few in and out.

Explaining the dehumidifying chamber 3, a thermoelectric module 5 is arranged in the longitudinal intermediate portion of the dehumidifying chamber 3, and a cooling body 6 is thermally conductively fixed to the heat absorbing surface of the thermoelectric module 5. The radiator 7 is fixed to the heat generating surface in a heat transfer manner.

The cooling body 6 is a little longer than the thermoelectric module 5 and has a large number of cooling fins 6 a. Both ends in the horizontal direction are arranged inside the side wall of the dehumidifying chamber 3, and the cooling fins 6 a are also in front of the dehumidifying chamber 3. It is placed on the front side of the wall.

On the other hand, the radiator 7 is vertically longer than the cooling body 6, and the bottom surface thereof is located at substantially the same height as the bottom surface of the cooling body 6 and extends above the cooling body 6. A large number of heat radiating fins 7a are provided, and both ends in the lateral direction are heat transfer-fixed to the side walls of the dehumidifying chamber 3, and the tips of the heat radiating fins 7a are heat transfer fixed to the partition wall 2.

At the bottom of the dehumidifying chamber 3, a water absorbent body 8 is disposed on the entire bottom surface, and the upper surface thereof is disposed below the lower surfaces of the cooling body 6 and the radiator 7. A space 9 forming a ventilation path is provided between the lower surface of the water absorber and the upper surface of the water absorber 8. As the water absorbent body 8, a thick non-woven fabric, felt, or sponge is used as the water absorbent fiber.

An intake port 10 is opened on the front wall of the dehumidifying chamber 3 facing the cooling body 6 at a position closer to the upper side with respect to the cooling body 6, and an exhaust port is formed on the upper side of the front wall on the same plane as the intake port 10. 11 is opened, and a fan 12 is installed in this exhaust port 11 part. A partition wall 13 that connects the front wall of the dehumidifying chamber 3 and the radiator 7 is provided above the cooling body 6 to prevent the air flowing from the intake port 10 from flowing upward.

Explaining the evaporation chamber 4 next, an exhaust port 14 is provided so as to project at a central portion of a rear wall facing the partition wall 2, and an exhaust fan 15 is installed at the exhaust port 14. There is.

Then, the water absorbing body 8 provided at the bottom of the dehumidifying chamber 3 extends into the evaporation chamber 4 through the opening 16 provided at the bottom of the partition wall 2 and extends along the partition wall 2 in the evaporation chamber 4. And extends upward and is fixed to the partition wall 2 by heat transfer so as to cover the entire surface of the partition wall 2.

The electronic dehumidifier 1 described above is installed in the closet 17 and is fixed to the wall surface of the partition wall 19 that partitions the closet 17 and the separate chamber 18, and the exhaust port 14 of the evaporation chamber 4 is provided in the partition wall 19. It is inserted in the opening 20.

The operation of the electronic dehumidifier 1 will be described below. When the thermoelectric module 5, the fan 12 of the dehumidifying chamber 3 and the fan 15 of the evaporation chamber 4 are energized by a power source (not shown), the air in the push-in chamber 17 flows into the dehumidifying chamber 3 from the intake port 10 by the fan 12. Then, the air flows to the cooling body 6.

On the other hand, the cooling body 6 is cooled by the thermoelectric module 5, and the surface temperature of the cooling body 6 becomes low and drops to the dew point temperature. Therefore, the air contacting the cooling body 6 is cooled by the cooling body 6. Moisture in the air is condensed on the surface of the cooling body 6.

The air dehumidified by the cooling body 6 flows into the radiator 7 side through the space 9 below the cooling body 6, cools the radiator 7, and is returned from the exhaust port 11 into the close-in 17. .. At this time, since the air passing through the radiator 7 is cooled by the cooling body 6, the heat of the radiator 7 can be taken away. As described above, the air in the closet 17 is constantly circulated and dehumidified in the dehumidifying chamber 3, so that the dry condition can be maintained and the stored items in the closet 17 can be stored in good condition.

Next, the discharge of the condensed water attached to the cooling body 6 will be described. Condensation attached to the surface of the cooling body 6 becomes water droplets and drops on the water absorbing body 8. This condensed water moves through the inside of the water absorber 8 to the water absorber 8 arranged on the evaporation chamber 4 side. Since the water absorbing body 8 on the side of the evaporation chamber 4 is in contact with the partition wall 2 made of a material having good thermal conductivity, the water absorbing body 8 is warmed by the heat transferred from the heat radiating body 7 to the partition wall 2 and the water content in the water absorbing body 8 is increased. The partition wall 2 is cooled at the same time when the evaporation of the is promoted. Further, the exhaust fan 15 of the evaporation chamber 4 discharges the air in the evaporation chamber 4 to the side of the separate chamber 18, but since the evaporation chamber 4 has no air inlet, the pressure in the evaporation chamber 4 is higher than that in the other chambers. It becomes low, and evaporation of water in the water absorbing body 8 is promoted. The water evaporated in the vaporization chamber 4 is discharged into the separate chamber 18 by the exhaust fan 15.

In this way, the water in the air in the push-in chamber 17 once becomes condensed water, but is evaporated in the evaporation chamber 4 and moved to the other chamber 18 side. Since the separate room 18 side is a large space, the humidity only slightly increases, and there is no problem as the environment of the living space.

2 to 3 show another example in which the radiator 2 also serves as the partition wall 2 of the electronic dehumidifier 1. Explaining below, the inside of the electronic dehumidifier 1 is divided into a dehumidifying chamber 3 and an evaporating chamber 4 which is arranged adjacent to the dehumidifying chamber 3 in the longitudinal direction, and the space between them is air. Very few people come and go.

Explaining the dehumidifying chamber 3, a thermoelectric module 5 is disposed in the longitudinal intermediate portion of the dehumidifying chamber 3, and its heat generating surface is heat conductively fixed to the radiator 30. The cooling body 6 is heat transfer-fixed.

The cooling body 6 is slightly longer than the thermoelectric module 5 and has a large number of cooling fins 6 a. Both ends in the horizontal direction are arranged inside the side wall of the dehumidifying chamber 3, and the cooling fins 6 a are also in front of the dehumidifying chamber 3. It is placed on the front side of the wall.

On the other hand, the radiator 30 partitions the inside of the electronic dehumidifier 1 into a dehumidifying chamber 3 and an evaporation chamber 4, and a large number of heat radiation fins 30 a are arranged in the evaporation chamber 4.

At the bottom of the dehumidifying chamber 3, a water absorbing body 8 is arranged on the entire bottom surface. As the water absorbent body 8, a thick non-woven fabric, felt, or sponge is used as the water absorbent fiber.

An intake port 10 is opened on the front wall of the dehumidifying chamber 3 facing the cooling body 6 at a position closer to the lower part with respect to the cooling body 6, and an exhaust port is formed on the upper side of the front wall on the same plane as the intake port 10. 11 is opened, and a fan 12 is installed in this exhaust port 11 part. A partition wall 31 extending from the front wall of the dehumidifying chamber 3 to a position in front of the radiator 30 is provided above the cooling body 6, and an opening 32 is formed between the tip of the partition wall 31 and the radiator 30.

Explaining the evaporation chamber 4 next, an exhaust port 14 is provided so as to project at a central portion of a rear wall facing the partition wall 2, and an exhaust fan 15 is installed at the exhaust port 14. There is.

Then, the water absorber 8 provided at the bottom of the dehumidifying chamber 3 extends into the evaporation chamber 4 through the opening 33 provided at the bottom of the radiator 30, and the heat radiation of the radiator 30 is made in the evaporation chamber 4. It extends upward along the fins 30a and is heat transfer-fixed to the radiator 30 so as to cover all side surfaces of the radiator fins 30a of the radiator 30.

The electronic dehumidifier 1 described above is installed in the closet 17 and fixed to the wall surface of the partition wall 19 that separates the closet 17 and the separate chamber 18, and the exhaust port 14 of the evaporation chamber 4 is provided in the partition wall 19. It is inserted in the opening 20.

The operation of the electronic dehumidifier 1 will be described below. When the thermoelectric module 5, the fan 12 of the dehumidifying chamber 3 and the fan 15 of the evaporation chamber 4 are energized by a power source (not shown), the air in the push-in chamber 17 flows into the dehumidifying chamber 3 from the intake port 10 by the fan 12. Then, the air flows to the cooling body 6.

On the other hand, the cooling body 6 is cooled by the thermoelectric module 5, and the surface temperature of the cooling body 6 becomes low and drops to the dew point temperature. Therefore, the air contacting the cooling body 6 is cooled by the cooling body 6. Moisture in the air is condensed on the surface of the cooling body 6.

The air dehumidified by the cooling body 6 is returned to the inside of the close-in 17 from the exhaust port 11 through the opening 32 between the front end of the partition wall 31 and the radiator 30 while cooling the radiator 30. It At this time, since the air passing through the radiator 30 is cooled by the cooling body 6, the heat of the radiator 30 can be taken away. As described above, the air in the closet 17 is constantly circulated to be dehumidified in the dehumidifying chamber 3 so that it can be kept in a dry state and the stored items in the closet 17 can be stored in good condition.

Next, the discharge of the condensed water attached to the cooling body 6 will be described. Condensation attached to the surface of the cooling body 6 becomes water droplets and drops on the water absorbing body 8. This condensed water moves through the inside of the water absorber 8 to the water absorber 8 arranged on the evaporation chamber 4 side. Since the water absorber 8 on the side of the evaporation chamber 4 is in contact with the heat radiator 30, it is warmed by the heat radiator 30 to accelerate evaporation of water in the water absorber 8 and at the same time cool the heat radiator 30. Further, the exhaust fan 15 of the evaporation chamber 4 discharges the air in the evaporation chamber 4 to the side of the separate chamber 18, but since the evaporation chamber 4 has no air inlet, the pressure in the evaporation chamber 4 is higher than that in the other chambers. The atmospheric pressure is lowered, and evaporation of water in the water absorber 8 is promoted. The moisture evaporated in the evaporation chamber 4 is discharged into the separate chamber 18 by the exhaust fan 15.

In this way, the water in the air in the push-in chamber 17 once becomes condensed water, but is evaporated in the evaporation chamber 4 and moved to the side of the separate chamber 18. Since the separate room 18 side is a large space, the humidity only slightly increases, and there is no problem as the environment of the living space.

The electronic dehumidifier 1 that also serves as the partition wall that separates the heat dissipator 30 from the dehumidifying chamber 3 and the evaporating chamber 4 can be made thin and lightweight, so that the protrusion from the wall surface on which the electronic dehumidifier 1 is mounted is reduced. can do.

Although the water absorber is arranged across the dehumidifying chamber 3 and the evaporation chamber 4, the size, position, etc. of the water absorber in each chamber 3, 4 are not limited to those shown above. Needless to say, for example, in the dehumidifying chamber 3, it is arranged directly below the cooling body 6 and extends to the evaporation chamber 4, and in the evaporation chamber 4, it goes upward along the partition wall 2 (or the radiator 30). It may be extended so as to cover a part of the partition wall 2 (or the radiator 30).

FIG. 4 shows an installation example of the electronic dehumidifier 1 in a house. Next to the living room 40, which has a large space, there are 6 tatami mats 41, and a closet 17 is provided in the mat 41. The electronic dehumidifier 1 is installed on the partition wall 19 between the closet 17 and the living room 40.

In the above description, the example in which the water in the evaporation chamber 4 is discharged to another chamber has been shown, but it goes without saying that the water may be directly discharged to the external space. As shown in FIG. 4, there is a closet 17 in a 6-tatami Japanese-style room 42 next to the living room 40, and one side of the closet 17 faces the balcony 43. Therefore, if the electronic dehumidifier 1 is installed on the partition wall 19A facing the balcony 43, the water in the evaporation chamber 4 can be discharged to the outside.

In FIG. 4, 44 is a balcony, 45 is a Western-style room, 46 is a kitchen, 47 is a toilet, 48 is a bathroom, 49 is a washroom, 50 is a dressing room, 51 is a hall, 52 is an entrance, 53 is a Western-style room, 54 Is a staircase and 55 is a balcony.

According to the electronic dehumidifier of the first and second aspects, the dehumidifying chamber of the dehumidifying chamber is compact and quiet, has a low electricity cost and is economical, and the dew condensation water in the dehumidifying chamber moves to the evaporating chamber through the water absorbing body. Since it evaporates and is discharged to the outside, it is convenient because water generated by dehumidification can be treated without requiring manpower, and it is ideal for dehumidification such as pressing.

According to the electronic dehumidifier according to the second aspect, the width of the electronic dehumidifier can be reduced.
