Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dehumidifying type clothes dryer that eliminates leakage of moist air in a circulating air path.

In conventional dehumidifying clothes dryers, air heated by a heater is sent into a rotating drum by a fan to absorb evaporated moisture from clothes.

The humid air is led to a heat exchanger, cooled by a cooling fan, the humid air is condensed, and the moisture that has separated is flushed out of the machine.The air that has separated is reheated and circulated inside the rotating drum. This device repeatedly dries clothes, but because the drain port that drains the condensed and separated water is open to the outside of the machine, some of the humid air circulates in the circulation air path. leaks out of the machine along with water, and as a result, the ratio of condensed water to evaporated water in the circulation air path decreases, reducing the amount of water recovered and increasing indoor humidity by that amount. Therefore, the dehumidifying type clothes dryer had the disadvantage that the intended purpose could not be fully achieved.This invention was made in view of the above points, so in this type of clothes dryer, a drain is installed at the drain port for discharging condensed water. By connecting the tank, condensed water can be stored without leaking humid air to the outside, and by opening the drain valve of the drain tank in conjunction with the opening of the pressure main body door, the condensed water can be stored without leaking humid air to the outside. The purpose is to provide a device that can drain only condensed water.

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

Figure 1 is a side sectional view, in which (1) is the outer box, (2
) is a rotating drum rotatably supported within the outer box (1), and is rotationally driven by a motor (3) and a drum belt (8a). (4) is a clothes inlet provided at the front of the rotating drum (2), (5) is a door that covers and opens and closes this clothes inlet (4), and (6) is a door at the lower edge of the clothes inlet. One end of the provided intake passage communicates with the inside of the rotating drum (2),
A heater (7) for heating the air is disposed within the passage. (8) sucks the air heated by this heater (7) into the rotating drum (2) as warm air;
A circulation fan that exhausts air through the drum exhaust port (9) to the exhaust passage (1 (j), which is rotationally driven by the motor (3) and the circulation fan belt (3b). Fins (lla) are implanted on the outer periphery of the tube constituting one main body of the heat exchanger for heat exchanger, which is disposed in full communication between the outlet l and the other end of the intake passage (6). 02 is the motor (3) and the cooling fan bell) (8
c) A cooling fan that is driven to blow air to the fins (lla); a'5 is a cooling fan casing that covers the cooling fan bottle; is facing. U is a drain port provided at the bottom of the intake passage (6) near the connection with the heat exchanger 0υ, H
is a drain tank connected to this drain port OQ, and a drain valve Oη is provided at the lower part. Is the drain valve 0 in Figure 2?
) shows an example of the drive mechanism. The decoy is a push rod fixed to the inside of the door (5), and when the door (5) is closed, it passes through the outer box (1) and is inserted into the interior. The Q duck is an L-shaped arm whose one end is pressed when the bushing rod is inserted, and rotates around the axis On against the tension spring.

@ is a straight arm whose one end is engaged with the other end of this L-shaped arm (I!1), and the other end is connected to the drain valve surface.

In the dehumidifying clothes dryer configured as described above, first open the door (5), put the clothes into the rotating drum (2) through the clothes inlet (4), and then close the door (5). When the power is turned on, the heater (7) generates heat and the motor (3)
) is driven. As a result, the drum belt (8a) drives the rotating drum (2), the circulation fan bell (8b) drives the circulation fan (8), and the cooling fan belt (3)
c) The cooling fans θ each rotate. Due to the rotation of the rotating drum (2), the wet clothes stored inside the drum repeatedly rotate and fall. Also heater (7)K
The warmer air is sucked into the rotating drum (2) by the circulation fan (8) through the air intake passage (6), where it comes into contact with the clothing, evaporates and absorbs moisture, and becomes moist air that flows into the drum. It is discharged from the exhaust port (9) into the exhaust passage OI. This humid air enters the heat exchanger θυ connected to the outlet of the exhaust passage θ1. On the other hand, this heat exchanger all has a cooling fan α
Since the outside where the fins (lla) are installed is cooled by the heat exchanger, the humid air that has entered the heat exchanger Uυ condenses into condensed water. In addition, air dehumidified by condensation is sucked in again by the circulation fan (8), passes through the heater (7), and enters the drum (2), which forms a circulation air path. Evaporates in the wind path,
Condensation occurs repeatedly, drying the clothes in the process.

Furthermore, the condensed water in the above process is discharged from the drain port 0!9 and accumulates in the drain tank αQ, but since the drain valve α9 of the drain tank αe is in the closed state while the dryer is operating, Humid air will not leak outside. Therefore, a large amount of condensed water can be collected in the drain tank αQ, thereby allowing operation without increasing the humidity in the operating location such as indoors. Next, when drying is completed and the clothes are taken out, the door (5) is opened, but at this time, the bushing stick (type 1) fixed to the inside of the door (5) must be removed from the main body, so the door (5) must be closed. At this time, the L-shaped arm member, which had been pushed in against the tension spring (to), becomes free and is pulled by the spring holder.This causes it to rotate around the axis t2g, so that the other end of the L-shaped arm a1 remains at the same position. The engaged linear arm (2
), the drain valve opens and the condensed water in the drain tank ae is drained all at once.

In addition, in the above embodiment, the operation of the drain valve αη that is linked to the opening and closing of the door (5) is shown as a mechanical operation, but this may also be an electrical operation, and the operation can be performed in conjunction with the door opening and closing operation that is always performed when using the dryer. It does not matter how the drain valve operates as long as it is linked [7].

As explained above, this invention eliminates leakage of humid air from the drain port by temporarily storing condensed water ff1 in the drain tank, and most of the moisture evaporated from clothes can be recovered as condensed water. , the water recovery performance of the dehumidifying dryer can be improved and the use of the dryer.

This provides the effect of maintaining a comfortable living environment without increasing the humidity in the living room.
