Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a clothes dryer (water-cooled heat exchanger),
In particular, by using a porous member between the water supply port of the water-cooled heat exchanger and the circulation air flow path, the water supply port and the end of the water supply valve are free from being connected as hoses or ducts as water channels. The present invention relates to a suitable water-cooling heat exchanger for a clothes dryer capable of allowing cooling water to flow in from outside without discharging hot air with high humidity when supplying cooling water.

[Conventional technology]

Conventionally, cooling water used in a water-cooled exchanger has been connected to a water supply port from a point of a water supply valve to a water supply port by a hose or the like.

[Problems to be solved by the invention]

In the above prior art, since a hose is used, the number of parts related to the hose is large, and it is necessary to seal so that cooling water does not leak from the hose.

An object of the present invention is to connect a water supply port and a water supply valve end with a hose or the like as a water passage without using a hose or the like, and to flow cooling water into a duct without discharging hot air with high humidity to the outside. Simple shape.

[Means for solving the problem]

The above object is to use a porous member between the water supply port and the inside of the duct, so that the porous member contains a large amount of cooling water flowing out of the water supply valve and is always in a cold state. The cooling water can flow into the duct. In addition, since the porous member is always in a cold state, when the high-humidity hot air in the duct tries to go out through the porous member, it is achieved by being cooled and dehumidified by the porous member. Is done.

[Action]

The porous member provided between the water supply port and the inside of the duct can contain a large amount of water and can flow water into the inside of the duct. Therefore, the hot air with high humidity that passes through the inside of the duct is not discharged to the outside by the water wall formed by the porous member containing water, but will be discharged to the outside. Even when it is, the porous member is always cooled by the water flowing from the water supply port, so the hot air with high humidity in the duct is cooled and dehumidified,
Since it is distributed outside, there is no malfunction such as humid air being discharged outside.

〔Example〕

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

FIG. 1 shows a configuration of a dehumidifying clothes dryer, and FIG. 2 is a plan view of a duct and a water supply port of a water-cooled water heat exchanger.
The figure shows a front sectional view of a duct and a water supply port of the water-cooled heat exchanger and a water supply valve, and FIG. 4 shows a right side view of the duct and the water supply port of the water-cooled heat exchanger.

In FIG. 1, a dehumidifying clothes dryer has an openable and closable lid 9 in which a laundry 10 can be put in and taken out substantially in the center of the case and a hot air of a drum 1 is sealed so as not to go out of the case 2.
At the lower part, a water-cooled heat exchanger cools and dehumidifies the hot air with high humidity in the circulating air flow path 5a, and condensed water generated by the water-cooled heat exchanger and drainage water for discharging cooling-like water used in the water-cooled heat exchanger. An opening and a ventilation opening communicating with a series of circulating air flow paths 5a to 5d are provided at appropriate positions. Inside the case 2, there is provided a cylindrical drum 1 rotatable via a pulley 3 and a rotating shaft 4 and having a ventilation hole formed as appropriate. (Hereinafter, abbreviated as drum 1.) A water-cooled heat exchanger 6, a blower fan 7, and a heater for drying are provided in the middle of a series of circulating air passages 5a to 5d.

The lid 9 that can be opened and closed is opened, the wet laundry 11 is put into the drum 2, the lid 9 is closed, and the drum 2 is rotated via the pulley 3 and the rotating shaft 4 to perform a drying process.

Drying heater 8 from blower fan 7 through duct 4c
(Q ₁ ), the air is heated to become warm air suitable for drying the clothes, and the warm air is sent into the case 2 through the duct 5d (Q ₂ ). The warm air sent into the case 2 hits the laundry 11 moistened through the ventilation holes provided in the drum 1 and becomes hot air with high humidity, and is discharged from the case 2 to the duct 5a (Q ₃ ). high discharge humidity from 5a hot air is sent into the water-cooling heat exchanger, after the cooling dehumidified, the dry air is sent to the duct 5b to passing connexion again blowing fan 7 (Q _4). Above, drying step is to repeat the Q ₁ to Q _4.

In FIG. 3, the water-cooled heat exchanger 6 is provided with a water supply port 12 and a water supply passage 12 'capable of supplying water to the inside at the upper part of the side surface. A porous member is provided between the water supply channel 11 'and the circulating air flow path of the water-cooled heat exchanger 6, and a water-cooled heat exchanger 14 is provided below the water-cooled heat exchanger. Have been. Above the water supply port, there is a water channel leading from the water supply valve 14, and between them, there is a free state in which nothing is connected.

Cooling water flows from the tap water through a water supply valve 14, through a water path ahead of the tap water, into a water supply port 12 of the water-cooled heat exchanger 6, and flows to a porous member 13 through a water supply path 12 '. The flowing cooling water permeates into the porous member 13, and the water, which has not been completely contained by the porous member, flows into the circulating air flow path in the water-cooled heat exchanger 6, and the water-cooled heat exchange is performed. Flows to the department.
At this time, the porous member 13 is always in a cold state by the cooling water flowing from the water supply port 12. The water-containing and cooled porous member forms a water wall, and the high-humidity hot air flowing through the water-cooled heat exchanger 6 is not discharged outside by the water wall. . Also, even if the air is discharged, it is cooled and dehumidified and goes out as dry air. Most of the hot air having a high humidity is cooled and dehumidified by the water-cooled heat exchanging section 14, and is sent to the fan through the circulation air flow path 5a. On the other hand, the condensed water and cooling water generated in the water-cooled heat exchange section 15 are discharged from the drain port 10.

〔The invention's effect〕

According to the present invention, a water-cooling type heat exchange unit is provided without a member such as a hose or the like at a water supply port and a water supply valve, and without discharging hot air having a high humidity flowing in a duct to outside. And it could be made into a very simple shape.
