Description

Description: TECHNICAL FIELD The present invention relates to a dehumidifier using an electronic cooling element or the like applied to a storage or the like.

[Background technology]

As a dehumidifier for a storage cabinet, the one shown in Fig. 2 was proposed.

The casing 1 forms an air passage 11 having an intake port 12 and an exhaust port 13 on the lower side and the upper side in the air blowing direction. The cooling body 3 is provided in the ventilation passage 11 in the vicinity of the intake port 12,
The radiator 5 is arranged in the vicinity of the exhaust port 13. The cooling body 3 and the radiator 5 are fin-shaped. In the electronic cooling element 2, the cooling part 2 a is joined to the cooling body 3, and the heat generating part 2 b is connected to the radiator 5 via the heat transfer body 4. Below the cooling body 3, a water storage tank 7 is provided to store the condensed water that has condensed on the cooling body 3 when it is dropped. The blower means 6 is a fan provided in the casing 1. 8
Is a power supply and control device. 10 is a filter.
20 is a storage.

According to this configuration, the humid air sucked in through the intake port 12 is condensed on the cooling body 3 when passing through the cooling body 3, dried by the radiator 5 and discharged through the exhaust port 13. The condensed water that has condensed on the cooling body 3 falls into the water storage tank 7 and is stored therein.

However, in this configuration, since the water storage tank 7 is filled with dew condensation water, it is necessary to perform processing such as taking the water storage tank 7 out of the casing 1 and draining it, and there is a problem that maintenance operation takes time. .

In order to save such trouble, there is a method of piping the water from the water storage tank 7 to the outside to guide the condensed water to the outside, but the piping work is troublesome.

[Object of the Invention]

An object of the present invention is to provide a dehumidifier that does not require the drainage treatment of dew condensation water, is easy to maintain, and is simple in construction.

[Disclosure of Invention]

The dehumidifier of the present invention includes a casing having a ventilation passage,
A cooling body which is arranged in the ventilation passage and causes dew condensation, and a water storage which is provided below the cooling body and which has a water receiving port and an external opening opened to the outside of the ventilation passage to receive and store the dew condensation water. The tank includes a tank and an evaporation unit that is disposed near the external opening of the water storage tank and that guides the condensed water to evaporate it outside the ventilation passage.

According to the configuration of the present invention, since the evaporation section for evaporating the condensed water to the outside of the ventilation path is provided on the external opening side of the water storage tank having the external opening opened to the outside of the ventilation path, it is stored in the water storage tank. The condensed water evaporates from the evaporating section to the outside of the ventilation path through the external opening. Therefore, drainage processing such as taking out the water storage tank to the outside of the casing and draining it is not necessary, and the maintenance operation is easy.

Moreover, piping work for drainage is not required, so the construction is simple.

Embodiment An embodiment of the present invention will be described with reference to FIG. This dehumidifier is provided with a casing 1 in which a ventilation passage 11 is formed, a cooling body 3 which is arranged in the ventilation passage 11 and which causes dew condensation, and which is located below the cooling body 3 and has a water receiving port 14 and a ventilation passage 11. A water storage tank 7 having an external opening 15 open to the outside for receiving and storing the condensed water is provided. The storage tank 7 is arranged in the vicinity of the external opening 15 and guides the condensed water to the ventilation passage 11 An evaporation unit 16 for evaporating outside is provided.

In FIG. 1, the water storage tank 7 is a box-shaped container arranged at the lower end of the casing 1. The water storage tank 7 has a water receiving port 14 through which the condensed water falling from the cooling body 3 is passed on the upper surface of one end.
And an external opening 15 open to the outside of the casing 1 at the upper side of the other end. The upper surface of the water storage tank 7 forms an inclined portion 7a whose height increases from the central portion toward the external opening 15 side.

The evaporation unit 16 is made of a water absorbent fiber material such as felt, and is arranged in the water storage tank 7 in the vicinity of the external opening 1. The evaporating section 16 is supported by a side surface on the side of the water receiving port 14 by a support fitting 18, has its lower end in contact with the bottom surface of the water storage tank 7, and rises to project from the water surface of the condensed water to extend to the vicinity of the inclined section 7a. 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 7.

The heater 17 is an electric heating body, is attached in contact with the side surface of the support fitting 18 on the side of the water receiving port 14, and applies heat to the evaporation section 16 via the support fitting 18.

Others are the same as those of the conventional example of FIG. 2, and therefore, the same reference numerals are given to the drawing and the description thereof will be omitted.

According to this configuration, the external opening 15 opened to the outside of the ventilation passage 11
Since the evaporation unit 16 for evaporating the condensed water to the outside of the ventilation passage 11 is provided on the external opening 15 side of the water storage tank 7 having the
It evaporates to the outside of the ventilation passage 11 through. At this time, the evaporation section
Since the heater 17 for applying heat to 16 is provided, the efficiency of evaporation is further improved. Therefore, drainage processing such as taking out the water storage tank 7 to the outside of the casing 1 and draining it is unnecessary, and the maintenance operation is easy.

Moreover, piping work for drainage is not required, so the construction is simple.

An ascending air current is generated by the heat of the heater 17 in the vicinity of the heater 17, and the upper surface of the water storage tank 7 forms an inclined portion 7a whose height increases toward the external opening 15, so that steam is easily discharged. Also, it is difficult for steam to return to the ventilation passage 11.

The evaporating portion 16 is an outer opening than the support fitting 18 and the heater 17.
Since it is arranged on the 15th side, the supporting metal 18 and the heater 17 form a wall, and it is difficult for steam to flow to the water receiving port 14 side and return to the ventilation passage 11.

Although the electronic cooling element 2 is used in the above embodiment, a heat pump type refrigerator may be used.

The evaporation part 16 may be immersed in the dew condensation water, and the condensation water may be guided to the evaporation part 16 by a water pipe or the like.

The evaporation unit 16 and the heater 17 may be brought into direct contact with each other.

The heater 17 may not be provided. In that case, the air contact area of the evaporator 16 may be increased to improve the evaporation efficiency.

The lower edge of the support fitting 18 may be attached to the water storage tank 7 via a heat insulating material.

〔The invention's effect〕

According to the dehumidifier of the present invention, since the evaporation portion for evaporating the condensed water to the outside of the ventilation passage is provided on the outside opening side of the water storage tank having the outside opening opened to the outside of the ventilation passage, the dehumidifier is stored in the water storage tank. The condensed water evaporates from the evaporating section through the external opening to the outside of the ventilation passage. Therefore, drainage processing such as taking out the water storage tank to the outside of the casing and draining it is not necessary, and the maintenance operation is easy.

Moreover, piping work for drainage is not required, so the construction is simple.
