Abstract

PURPOSE:To make the maintenance operation easy by a method wherein a humidifier utilizing thermoelectric cooling elements, etc., is equipped with a vaporizing part vaporizing condensate water in a water storage tank having a water receiving port located under a cooling unit and an outside opening part opened outside a ventilating flue. CONSTITUTION:In a water storage tank 7 with a water receiving port 14 located under a cooling unit 3 and an outside opening part 15 opened outside a ventilating flue 11 placed is a vaporizing part 16 vaporizing condensate water. Therefore, the condensate water collected in the tank 7 through the port 14 keeps on vaporizing outside the flue 11 through the part 15 by means of the part 16. At that time, as a heater 17 heating the part 16 is placed, vaporization efficiency is more improved. Therefore, waste water disposal, such as drainage by taking out the tank 7 outside a casting 1, etc., is not necessary.

Description

[Detailed description of the invention] 〔Technical field〕 The present invention relates to an electronic cooling element that is applied to storage cabinets and the like.

This article relates to a dehumidifier using a dehumidifier.

[Background technology]

Conventionally, dehumidifiers for storage sheds store the removed condensed water in a water storage tank, and when it becomes full, the water storage tank is taken out and treated as wastewater. Therefore, there was a problem in that maintenance operations were time-consuming.

Additionally, in order to avoid such trouble, there is a method of piping the water from the water storage tank to the outdoors to guide the condensed water outdoors, but the piping work is time-consuming.

Therefore, we proposed what is shown in Figure 4.

In the figure, casing l is the intake port! 2 and exhaust port 13
Ventilation passage 1' having on the lower side and on the upper side of the ventilation direction
It forms a l. In the ventilation path II, a cooling body 3 is arranged near the intake port 12 and a heat sink 5 is arranged near the exhaust port 13. The cooling body 2 and the heat radiating body 5 have a fin shape.

The electronic cooling element 2 has a cooling part 2a joined to a cooling body 3,
The heat generating part 2b is connected to the heat sink 5 via the heat transfer body 4.

The water tank 30 is a box-shaped container arranged at the lower end of the casing 1. The water storage tank 30 has a water socket 14 on the upper surface of one end through which the condensed water that falls from the cooling body 3 passes, and has an external opening I5 open to the casing 1 on the upper side of the other end. The upper surface of the water storage tank 30 has a sloped portion 3 whose height increases from the center toward the external opening 15.
0a is formed.

The evaporator 16 is arranged near the external opening 15 within the water storage tank 30. The evaporator 16 is made of a water-absorbing fiber material such as felt, and its lower end is connected to the bottom surface 30b of the water storage tank 30.
The side surface of the water socket 14 is held by a support fitting 18 so that the rising condensed water protrudes from the water surface. 14 shots part 16
sucks condensed water upward. The support fitting 18 is an L-shaped member made of a heat conductive material such as aluminum, and its lower edge is attached to the bottom surface of the water storage tank 30.

The heater 17 is an electric heating element, and the water socket 1 of the support fitting 18
It is attached in contact with the side surface of the 4 side, and the support metal fitting 18
Heat is applied to the evaporation section 16 via the evaporator.

The blowing means 6 is a fan provided inside the casing l. 8 is a power source and a control device. 10 is a filter. 20 is a storage.

According to this configuration, humid air taken in through the intake port 12 condenses on the cooling body 3 when passing through the cooling body 3, is dried by the heat radiating body 5, and is discharged through the exhaust port 13. The condensed water that has condensed on the cooling body 3 falls into the water storage tank 30 and is stored there, and is emitted outside the ventilation passage 11 by the evaporator 16. Therefore, the water storage tank 30 is taken out of the casing 1 and drained, etc. It does not require wastewater treatment and is easy to maintain.

Furthermore, construction is simple as no piping work is required for drainage.

In the vicinity of the heater 17, an upward air current is generated due to the heat of the heater 17, and the upper surface of the water storage tank 30 forms an M-slanted portion 30a that increases in height toward the external opening 15, so steam is easily discharged. , Also, it is difficult for steam to return into the ventilation path ll.

However, with this configuration, a certain amount of steam still enters the ventilation passage 11 from the water inlet 14, reducing the dehumidifying ability of the dehumidifier.
