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 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.

Next, the evaporation chamber 4 will be described. An exhaust port 14 and an intake port 21 around the exhaust port 14 are provided in a central portion of a rear wall facing the partition wall 2 so as to protrude from the exhaust port 14. The exhaust fan 15 is installed.

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 inside the evaporation chamber 4, the side surface of the partition wall 2 is formed. It extends part way up with a gap.

A heater 22 for promoting evaporation of water in the water absorbing body 8 is inserted and arranged in the water absorbing body 8 of the evaporation chamber 4. The heater 22 is a plate heater that heats up to about 40 ° C.

The above electronic dehumidifier 1 is installed in the closet 17 and is 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 and the intake port 21 of the evaporation chamber 4 are connected to the partition wall. It is inserted into an opening 20 provided in 19.

The operation of the electronic dehumidifier 1 will be described below. When the thermoelectric module 5, the fan 12 of the dehumidifying chamber 3, the fan 15 of the evaporation chamber 4, and the heater 22 are energized by a power source (not shown), the air in the push-in unit 17 is pushed by the fan 12 from the intake port 10. Air flows into the dehumidifying chamber 3 and 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. The water in the water absorbing body 8 of the evaporation chamber 4 is heated by the heater 22 to promote evaporation. The water 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.

FIG. 2 shows 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 arranged 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 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 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 and an intake port 21 around the exhaust port 14 are provided so as to project at the center of the rear wall facing the partition wall 2, and The exhaust fan 15 is installed.

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 inside the evaporation chamber 4. It extends part way up with a gap from the fin 30a.

A heater 22 for promoting evaporation of water in the water absorbing body 8 is inserted and arranged in the water absorbing body 8 of the evaporation chamber 4. The heater 22 is a plate heater that heats up to about 40 ° C.

The above electronic dehumidifier 1 is installed in the closet 17 and is 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 and the intake port 21 of the evaporation chamber 4 are connected to the partition wall. It is inserted into an opening 20 provided in 19.

The operation of the electronic dehumidifier 1 will be described below. When the thermoelectric module 5, the fan 12 of the dehumidifying chamber 3, the fan 15 of the evaporation chamber 4, and the heater 22 are energized by a power source (not shown), the air in the push-in unit 17 is pushed by the fan 12 from the intake port 10. Air flows into the dehumidifying chamber 3 and 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 discharging 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. The water in the water absorbing body 8 of the evaporation chamber 4 is heated by the heater 22 to promote evaporation. The water 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.

In the above two embodiments, the intake port 21 of the evaporation chamber 4 may be used as the exhaust port, the exhaust port 14 of the evaporation chamber 4 may be used as the intake port, and the exhaust fan 15 of the evaporation chamber 4 may be used as the intake fan.

Further, the evaporation chamber 4 may be provided only with an exhaust port without providing an intake port, and an exhaust fan for exhausting the air in the evaporation chamber 4 to the outside may be provided.

Although the above two examples show the configuration in which the moisture evaporated in the evaporation chamber 4 is discharged to the outside by the forced exhaust of the fan, the moisture may be discharged by the natural exhaust as shown below.

FIG. 3 shows an example thereof, and since the configuration on the dehumidifying chamber 3 side is the same as the example of FIG. 1 described above, description thereof will be omitted, and only the evaporation chamber 4 side will be described.

In this example, the evaporation chamber 4 is not provided with the exhaust port 14, the exhaust fan 15, and the intake port 21 around the exhaust port 14 provided in the central portion of the rear wall in the example of FIG. It is configured so that there are no openings, and openings 23 and 24 are provided at the end portions of the upper wall and the bottom wall near the rear wall, respectively. The water absorbing body 8 extending from the dehumidifying chamber 3 side to the evaporation chamber 4 in the same manner as in the example of FIG. 1 has a gap in the evaporation chamber 4 with the side surface of the partition wall 2 as in the example of FIG. Thus, the space between the partition wall 2 and the opening 24 in the bottom wall is extended upward, and the heater 22 is inserted therein. The heater 22 is a plate heater that heats up to about 40 ° C.

The electronic dehumidifier 1 is slightly inserted into and fixed to an opening 20 A provided in the wall surface of the partition wall 19 that partitions the closet 17 and the separate chamber 18, and the two openings 23 and 24 of the evaporation chamber 4 are fixed. It faces the separate room 18.

Therefore, the water in the water absorbing body 8 of the evaporation chamber 4 is heated by the heater 22 to accelerate the evaporation. On the other hand, the partition wall 2 fixed to the radiator 7 by heat transfer exerts the effect of heat dissipation, warms the air in the evaporation chamber 4, and the heated air and moisture rise in the evaporation chamber 4. The exhaust gas is exhausted from the upper opening 23 to the separate chamber 18 due to the chimney effect of the ascending airflow.

It goes without saying that the above natural exhaust structure can be applied to a structure in which the radiator is also used as the partition wall.

Although the water absorbent body is disposed across the dehumidifying chamber 3 and the evaporation chamber 4, the size and position of the water absorbent body in each of the chambers 3 and 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, the upper end along the partition wall 2 (or the radiator 30). It may be arranged up to the position.

Further, it goes without saying that the performance, shape, arrangement position, etc. of the heater are not limited to those shown in the above embodiment.

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 changing room, 51 is a hall, 52 is an entrance, 53 is a Western-style room, 54 Is a staircase and 55 is a balcony.

[Effect of the device]

 According to the electronic dehumidifier of claims 1 and 2, 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 and evaporates there to the outside. Since it is discharged, it is convenient to treat the water generated by dehumidification without requiring human intervention, and it is ideal for dehumidification such as push-in. Further, the heater has an advantage that evaporation of water in the water absorbing body is promoted.

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