Abstract

PURPOSE:To provide a dehumidifier in which the size can be made small and the weight light and, further, the capacity to store water is large by connecting successively with heat transfer means the heat absorption faces of the heat radiation faces of each Peltier effect element from the most forward-step Peltier effect element to the last-step Peltier effect element. CONSTITUTION:A dehumidifier for heat exchanging employs in combination the heat absorption faces 10a and 11a and heat radiation faces 10b and 11b of Peltier effect elements 10 and 11. When electric current is supplied to each of Peltier effect elements 10, 11 and a blower 18, the wind flows as shown by the arrow mark in the figure, and cooling of the heat absorption face 10 proceeds. The moisture in the air which passes through the inside of a wind circuit 5 condenses on the surfaces of fins 12 to become water drops. They drop down to a water receiving pan 15 and the water is poured into a water storage tank 6 from a discharge opening 16. The air that has passed among the fins 12 is heated when it passes through fins 13 and blown out from a blow-out opening 4. With this arrangement a refrigerating cycle construction such as compressore, etc. is not needed, and it is possible to make the device small in size and light in weight and make the capacity of the water storage tank very large.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a dehumidifier that adjusts the degree of insularity in a room.

BACKGROUND OF THE INVENTION Conventionally, this type of dehumidifier was manufactured by the Utility Model Publication Co., Ltd.
As is known from Publication No. 204, etc., the structure was equipped with a refrigeration cycle consisting of a compressor, a condenser, a pressure reducer, an evaporator, and the like.

Problems to be Solved by the Invention In the conventional dehumidifier described above, it is difficult to reduce the size and weight of the dehumidifier because the parts that make up the refrigeration cycle are heavy and relatively large, and they must be connected with piping. Also, since there were many moving parts (compressor, blower, etc.), there was a lot of noise. Furthermore, since the compressor occupies a large space and the capacity of the water storage container cannot be increased, the dehumidified water must be frequently disposed of, which is a hassle.

In view of the above-mentioned conventional problems, the present invention provides a dehumidifier that is small and lightweight, and has a large water storage capacity.

Means for Solving the Problems In order to solve the above problems, the present invention uses a heat exchange dehumidifier as a Peltier effect element, and a heat absorption surface and a heat radiation surface of the Peltier effect element extend into the wind circuit section. The basic solution is to provide heat exchange fins to serve as a heat absorbing section and a heat dissipating section.

Further, the present invention provides a heat exchange dehumidification device in which a plurality of Peltier effect elements are arranged in parallel, and the heat dissipation surface and the heat absorption surface of each Peltier effect element are sequentially adjusted from the first stage Peltier effect element to the last stage Peltier effect element. The solution is to connect them using heat transfer means.

Effect: With this means, indoor dehumidification is achieved by making the indoor temperature substantially uniform and suppressing its rise due to the heat absorption and heat dissipation effects of the Peltier effect element.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the accompanying drawings.

In FIGS. 1 and 2, 1 is a dehumidifier main body, inside of which a partition plate 2 serves as a wind circuit section 5 having an inlet 3 and an outlet 4 at the upper part, and a water storage tank 6 at the lower part. It is partitioned into 7 spaces. The wind circuit section 5
Inside, a heat transfer section 9 is formed above by the top plate 8, and if necessary, a heat insulating material (not shown) can be provided to prevent heat leakage. 10 and 11 are well-known Peltier effect elements, respectively, fins 12 and 13, and a heat pipe 1.
4 etc. constitute a heat exchange dehumidification device.

As shown in FIG. 3, this heat exchange dehumidification device exhibits a heat exchange dehumidification function by using a combination of heat absorption surfaces 10a and 11a and heat radiation surfaces 10b and llb of each Peltier effect element 10 and 11.

That is, the heat absorption surface 10 of the Peltier effect element 10 on the windward side
On the heat dissipation surface 11b of the Peltier effect element 11 on the leeward side and m, there are heat dissipation fins 12 and 1 extending into the wind circuit section 6, respectively.
3 are provided for heat transfer, and consideration is given to improving heat exchange efficiency. And each Peltier effect element 10
・For the remaining surfaces of 11, the heat of the heat radiation surface tab is transferred to the heat absorption surface 11a.
It is connected by a well-known side pipe 14 for efficient transmission. In this way, each Peltier effect element 1
The heat-absorbing surface 10, which contributes to the actual heat exchange and dehumidification effect, connects the heat-radiating surface 10b and the heat-absorbing surface 11a of 0.11 in a conductive manner.
This is to increase the efficiency (capacity) of the a1 heat dissipation surface 11b.

Reference numeral 15 denotes a water tray provided at the lower part of the fin 12, and a part thereof is provided with a drain port 16 extending to the water storage space 7. Reference numeral 17 denotes a water inlet provided at the upper part of the water storage tank 6, which faces the drain port 16 when the water storage tank 6 is stored in the water storage space 7 in a normal state. The water storage tank 6 is configured so that it can be freely taken out from the water storage space 7 and stored. Reference numeral 18 denotes an air blower provided in the air circuit section 5, which blows air so that the air from the suction port 3 passes through the fins 12 and 13 in sequence and is blown out from the air outlet 4.

In the above configuration, when the Peltier effect elements 10 and 11 and the blower 18 are energized in the state shown in FIG. 1, the wind flows as shown by the arrow. As time passes, the Peltier effect element 1
Cooling of the endothermic surface 10a of the fin 10 progresses, the fin 12 is cooled, and moisture in the air passing through the wind circuit section 5 condenses as it passes through the fin 12 and adheres to the surface of the fin 12, becoming water droplets. The air that has passed through the fins 12 is warmed when passing through the fins 13 and is blown out from the outlet 4 with its relative humidity reduced.

As the above conditions continue, the water droplets attached to the fins 12 grow and fall onto the water tray 15 due to their own weight, and then
The water is poured into the water storage tank 6.

Therefore, according to the dehumidifier having such a configuration, the following effects can be obtained.

(1) Since there are few moving parts, there is extremely little noise and quiet operation is possible.

(2) A conventional refrigeration cycle structure such as a compressor is not required at all, making it compact and lightweight, and there are no conditions that restrict the capacity of the water storage tank 6, so the capacity of the water storage tank 6 can be set extremely large. This eliminates the need for frequent drainage operations, improving usability.

(3) Mutual heat dissipation surface 10 of Peltier effect elements 10 and 11
b and the endothermic surface 11a are connected thermally to achieve a heat exchange dehumidification effect (
Because it has a large capacity (capacity), it requires relatively low input and consumes less power than conventional models.

In addition, in the above embodiment, the Peltier effect element 10.
Although I used two 11's, it goes without saying that the number can be changed from one to as many as necessary depending on the ability. In particular, when there is only one, it is difficult to blow the air in a straight line as in the previous embodiment, and the air needs to be sent in a curved line as shown in FIG.

In this figure, there is a major difference from the configuration shown in FIG.
This is the point of unifying the . Dehumidification is also possible in this case.

Effects of the Invention As described above, in the present invention, by using a Peltier effect element having no moving parts for the heat exchange dehumidification function, noise can be reduced and a dehumidifier with low power consumption can be obtained. In addition, the conventional refrigeration cycle is no longer required, making it smaller and lighter, and by eliminating the need for a compressor, which has traditionally been an obstacle to increasing the capacity of water storage tanks, it is possible to increase the capacity of water storage tanks. As a result, frequent drainage work is no longer necessary, and the usability is improved.

By increasing the dehumidification capacity, even greater dehumidification capacity can be obtained.
