Abstract

PURPOSE:To reduce the size and weight of a dehumidifier and facilitate the incorporation of the same, by connecting respective Peltier effect elements mutually through thermal conduction. CONSTITUTION:The heat absorbing surface 10a of an upstream side Peltier effect element 10 and the heat radiating surface 11b of a downstream side Peltier effect element 11 are provided with fins 12, 13, extended into an airflow circuit 5 so as to be capable of conducting heat respectively. The remaining surfaces of respective Peltier effect elements 10, 11 are connected through a heat pipe 14. When the Peltier effect elements 10, 11 and a fan 18 are conducted, the heat absorbing surface 10a of the Peltier effect element 10 is cooled and the fins 12 are cooled whereby moisture in air which passes through the airflow circuit 5 is condensed when it passes through the fins 12 and water drips adhere to the surface of the fins 12. The air, which passed through the fins 12, is heated upon passing through the fins 13 and is blown off through a blow-off port under a condition that the relative humidity thereof is reduced. According to this method, the connecting work of pipelines for constituting a refrigerating cycle is not necessitated, a heat exchanging and dehumidifying device may be unified and the assembling work of a dehumidifier may be simplified.

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a dehumidifier for dehumidifying a room.

Conventional technology Conventionally, as a dehumidifier for this ridge, for example,
As is known from Publication No. 2049, etc., the structure was equipped with a refrigeration cycle consisting of a compressor, a nitrogen condenser, a pressure reducer, an evaporator, and the like.

Problems to be Solved by the Invention In conventional dehumidifiers, the parts that make up the refrigeration cycle are heavy and relatively large, and they must be connected with piping, so it is difficult to make them smaller and lighter. Because there were many moving parts (compressor, blower, etc.), there was a lot of noise.

Furthermore, a means for moving the components and piping that constitute the refrigeration cycle is required, and it is extremely difficult to unitize such equipment for easy installation.

In view of the above-mentioned conventional problems, the present invention aims to reduce the weight of the small 71 and furthermore provide a fastener that is easy to assemble. It is a purpose.

In order to solve the problem, the present invention provides a heat exchange dehumidifying device to solve the problem. , a plurality of Peltier effect elements arranged in parallel, a fin member that comes into contact with the heat absorption surface or the heat radiation surface of each Peltier effect element, and a Peltier effect element that comes into contact with the other surface of each of the Peltier effect elements and together with the fin member. The device has a unit structure including a cover member that sandwiches the Peltier effect elements, and a connecting member that connects each of the Peltier effect elements in a traditional rod-like manner.

Function: With this means, the room is dehumidified while keeping the indoor temperature substantially uniform through the heat absorption and heat radiation effects of the Peltier effect element.

Furthermore, by unitizing the heat exchange dehumidifier, assembly work as a dehumidifier can be facilitated.

Further, when unitizing the heat exchange dehumidifying device, there is no need to attach complicatedly curved piping, etc., and the unitizing work becomes easy.

EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIGS. 1 and 2, 1 is the dehumidifier main body, and the interior is 1. The upper part is the inlet 3 and the outlet 4 by the IJ plate 2.
The wind circuit section 5 is partitioned so that the lower part thereof becomes a water storage space 7 in which a water storage tank 6 is accommodated. Inside the wind circuit section 5, a heat transfer section 9 is formed in the L direction by the top plate 8, and if necessary, a heat insulating material (not shown) can be provided to prevent heat leakage. Reference numerals 10 and 11 are well-known Peltier effect elements, and a heat exchange dehumidifying device is constructed by fins 12 and 13 made of a thermally conductive material such as aluminum, a heat pipe 14, and the like.

As shown in FIGS. 3 and 4, this heat exchange dehumidification device has heat absorption surfaces 10a and I La of each Peltier effect element 10 and 11.
A heat exchange dehumidifying function is achieved by the combination of the heat radiating surfaces 10b and 11b.

That is, the heat absorption surface 10 of the Peltier effect element 10 on the windward side
Fins 12 and 13 are provided on the heat dissipation surfaces 11b of the Peltier effect elements 11 on the leeward side and a, respectively, extending into the wind circuit section 5.
are provided for heat transfer, and are designed to improve heat exchange efficiency.

The remaining surfaces of each of the Peltier effect elements 10 and 11 are connected by a well-known heat pipe 14 so that the heat from the heat radiation surface 10b is efficiently transferred to the heat absorption surface 11a.

In this way, the heat radiation surface 10 of each Peltier effect element 10, 11
The purpose of thermally connecting the heat absorbing surface 10a and the heat absorbing surface 11a is to increase the efficiency (ability) of the heat absorbing surface 10a and the heat dissipating surface 11b, which contribute to the actual heat exchange and dehumidification effect. Further, each of the Peltier effect elements 10 and 11 and the heat pipe 14 are sandwiched and fixed by the fins 12 and 13 and the cover members 20 and 21 to form a unit. The specific fixing means is preferably adhesive means, screwing means, or the like.

This unitized heat exchange dehumidification device has a top plate 8.
The through hole 8a formed in the fist 8b is connected to each fin 12 and 13.
are arranged so as to penetrate through the fins, and removal is prevented by abutment of the 7 flanges 12a and 13a at both ends of each fin 12 and 13 against the top plate 8. If necessary, fix it with screws, etc.
It may be fixed.

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 L old configuration, when power is applied to each of the Peltier effect cables 10 and 11 and the feeder 1[1aa18] in the state shown in FIG. 1, the wind flows as shown by the arrow. As time passes, the cooling of the heat absorption surface 10a of the Peltier effect element 10 progresses, the fins 12 are cooled, and the moisture in the air passing through the wind circuit section 5 is removed from the fins 12.
When passing through the water, it condenses and becomes attached to the surface of the fin 12, becoming water droplets. The air that has passed through the fins 12 is heated when it passes through the fins 13, and the humidity is reduced by 1.
The air is blown out from the air outlet 4 due to the operation.

As the above conditions continue, water droplets adhering to the fins 12 are removed! The water falls to the water tray 15 due to its own weight, and is poured into the water storage tank 6 through the drain port 16.

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

(1) Because 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. , there is no need for frequent drainage operations (the samurai's mukaiku is removed).

(3) Mutual heat dissipation surface 10 of Peltier effect element 10@11
b and r! & Since the heat exchange dehumidification device (capacity) is increased by thermally connecting the heat surfaces 11a, it requires relatively less man power and consumes less power than the conventional method.

(4) The heat exchange dehumidifier is unitized, and the installation of the heat exchange dehumidifier is completed by fitting the fins 12 and 13 into the through holes 8a and 8b of the top plate 8 and fixing them, so it is not necessary to refrigerate as in the past. Compared to the work of assembling a cycle, this is a 18] type of work.

In addition, in the embodiment described above, the Peltier effect element 10.
Although I used 11 for 21, it is possible to change the attack from 11 to 21 depending on the need for the ability.
not. ``Furthermore, the heat conductive connection of the Peltier effect elements is not limited to serial conduction between heat radiation and heat absorption, but may be made to connect heat radiation to each other and heat absorption to each other to improve overall performance.

As can be seen from the effects of the invention, the present invention uses a Peltier effect element with no moving parts for the heat exchange dehumidification function, thereby reducing noise and providing a dehumidifier with low power consumption.

In addition, since there is no need for pipe connection work for configuring a refrigeration cycle as in the past, the heat exchange dehumidification device can be easily formed into a unit, and the assembly work efficiency is reduced to 1.

Furthermore, since a plurality of Peltier effect elements are used in the heat exchange dehumidification device, and the efficiency is increased by mutual heat transfer, a large dehumidification capacity can be obtained.
