Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a dehumidifier that dehumidifies indoor rooms.

Conventional technology Conventionally, this type of dehumidifier was manufactured by Jikosho, for example.
As is known from Publication No. 58-6504, 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, in order to configure the refrigeration cycle, means for routing piping is required, and it is extremely difficult to form such equipment into a unit for easy installation.

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, it is an object of the present invention to achieve a smaller size and lighter weight, and to facilitate installation.

Means for Solving the Problems In order to solve the above problems, the present invention provides a heat exchange dehumidifier that is connected to a plurality of Peltier effect elements arranged in parallel and to the heat absorption surface or heat radiation surface of each Peltier effect element. a fin member, a cover member that contacts the other surface of each of the Peltier effect elements and clamps the Peltier effect element together with the fin member, and a connecting member that connects each of the Peltier effect elements in a thermally conductive manner. It has a unit structure.

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,
The assembly work as a dehumidifier is facilitated.

Further, when unitizing the heat exchange dehumidifying device, there is no need to perform the tedious work of brazing complicatedly curved piping, etc., making the unitizing work easier.

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

In Figures 1 and 2, 1 is the dehumidifier main body,
The interior thereof is partitioned by a partition plate 2 so that the upper part becomes a wind circuit section 5 having an inlet 3 and the outlet 4, and the lower part becomes a water storage space 7 that accommodates a water storage tank 6. Inside the wind circuit section 5, 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. Reference numerals 10 and 11 are well-known Peltier effect elements, respectively, and fins 12 and 13 made of a thermally conductive material such as aluminum constitute a heat exchange dehumidifying device with a heat pipe 14 and the like.

This heat exchange dehumidification device has heat absorption surfaces 1 of each Peltier effect element 10, 11 as shown in FIGS. 3 and 4.
A heat exchange dehumidification function is achieved by using a combination of 0a, 11a and heat radiation surfaces 10b, 11b.

That is, on the heat absorption surface 10a of the Peltier effect element 10 on the windward side and the heat radiation surface 11b of the Peltier effect element 11 on the leeward side, fins 12 and 13 extending into the wind circuit section 5 are respectively provided for heat transfer. , consideration has been given to improving heat exchange efficiency. The remaining surfaces of each Peltier effect element 10, 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 10b and the heat absorption surface 11a of each Peltier effect element 10, 11
The reason why they are thermally connected is to increase the efficiency (ability) of the heat absorption surface 10a and the heat radiation 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
The fins 12 and 13 and the cover members 20 and 21 are sandwiched and fixed to form a unit. The specific fixing means is preferably adhesive means, screwing means, or the like.

In this unitized heat exchange dehumidification device, the fins 12 and 13 are arranged so as to pass through through holes 8a and 8b formed in the top plate 8, and flanges 12a and 13a at both ends of each fin 12 and 13 It is prevented from coming off by coming into contact with the top plate 8. If necessary, it may be fixed by screws or the like.

Reference numeral 15 denotes a water tray provided at the lower part of the fin 12, and a part thereof has a drain port 16 extending to the water storage space 7.
is provided. 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 such 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 each Peltier effect element 10, 11 and the blower 18 are energized in the state shown in FIG.
The wind flows like an 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 condensed on the surface of the fins 12. It adheres to the surface and becomes 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, fall onto the water tray 15 due to their own weight, and are poured into the water storage tank 6 from the drain port 16.

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

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

(2) There is no need for a conventional refrigeration cycle structure such as a compressor, 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) Since the mutual heat dissipation surface 10b and heat absorption surface 11a of the Peltier effect elements 10 and 11 are thermally connected to increase the heat exchange dehumidification efficiency (capacity), the input is relatively low and compared to the conventional one. This also reduces power consumption.

(4) The heat exchange dehumidifier is integrated into a unit, 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. This is a simpler task compared to the task of assembling a cycle.

In the above embodiment, two Peltier effect elements 10 and 11 are used, but it goes without saying that the number can be changed from one to as many as necessary depending on the required performance. 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 performed to increase the overall performance by connecting heat radiation to each other and heat absorption to each other.

Effects of the Invention As described above, 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.

Further, since there is no need for piping connections for configuring a refrigeration cycle as in the past, the heat exchange dehumidifier can be easily integrated into a unit, and the assembly work is simplified.

Furthermore, a plurality of Peltier effect elements are used in the heat exchange dehumidification device to increase overall performance through mutual heat transfer, resulting in a large dehumidification capacity.
