Abstract

PURPOSE:To simplify a seal structure of a door part, etc., by a simple constitution, and to reduce the cost by providing a communicating part for communicating with the outside of a machine, on the downstream side of a ventilation device in a circulating air course. CONSTITUTION:In a frame of a closed structure, the inside is partitioned vertically by a partition plate 2, and divided into a drying chamber 3 and a recovery chamber 4. A communicating tube 28 provided in the vicinity of a discharge port 27 on the rear face of the recovery chamber 4 allows the inside and the outside of the recovery chamber (frame 1) to communicate with each other. When clothes washed by a petroleum compound solvent and dehydrated are contained in a drum 5, and a fan motor 25, a heater 29 and a cooler 30 are driven, drying air circulates in the frame 1 as indicated with a full line of an arrow by a fan 24. Since the communicating tube 28 is provided in a circulating path of this drying air, the downstream side of the fan 24 comes to communicate with the outside of the machine, the circulating path, that is, the inside of the frame 1 becomes a negative pressure characteristic, and pressure is applied between a door 11 and a throw-in port 10 and to a bearing 7 part as indicated with a dotted line of an arrow. Accordingly, it does not occur that drying air leaks out of this part.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to clothes dryers.

0002

2. Description of the Related Art As a conventional example, a blower device for circulating drying air in a circulating air path whose path includes a drying chamber for storing clothes, a cooling device for cooling the drying air,
A clothes dryer equipped with a heating device for heating drying air is disclosed in Japanese Utility Model Application Laid-Open No. 63-48952 (D06F43/0
8).

0003

[Problems to be Solved by the Invention] In the conventional example, a large amount of drying air tends to leak from the gap between the clothes input port to the drying room and the door that closes it, and the seal in this area The problem is that the structure must be made stronger, which increases costs accordingly.

[0004] In particular, when drying clothes after washing using petroleum-based solvents, if a large amount of vaporized solvent leaks outside the machine, odor and health problems are likely to occur.

[0005] The present invention relates to an improvement of a clothes dryer and is intended to solve these problems.

[0006]

[Means for Solving the Problems] The clothes dryer of the present invention includes:
A blower device for circulating drying air, a cooling device for cooling the drying air, and a heating device for heating the drying air in a circulating air path that includes a drying room for storing clothes as part of the path. and a communication portion communicating with the outside of the machine is provided on the downstream side of the blower device in the circulation air path.

[0007]

[Function] In other words, since the downstream side of the air blower in the circulation air path is connected to the outside of the machine, the inside of the circulation air path has a negative pressure characteristic, and drying air flows from the gap between the clothes slot and the door. There is no leakage, and on the contrary, a small amount of outside air is sucked in from this area due to negative pressure. This suctioned amount is discharged outside the machine from the communication part, but it is a very small amount so there is no problem.

Embodiments Examples of the present invention will be explained based on the drawings.

In FIG. 1, reference numeral 1 denotes a frame with a closed structure, the interior of which is partitioned into a drying chamber 3 and a recovery chamber 4 by a partition plate A2. 5 is a drying drum disposed in the drying chamber 3, and its rotating shaft 6 is connected to the drying chamber 3.
It penetrates through the rear surface of and is supported by a bearing 7. Reference numeral 8 indicates a clothing input port A provided on the front surface of the drum 5;
- indicates a large number of small holes drilled around the drum 5; 10 indicates a clothing input port B provided in the drying chamber 3 at a location opposite to the input port A8; and 11 indicates a clothing input port B10 that is closed. The door 12 has pulleys 13 and 14 on the rotating shaft 6.
and a motor connected via a belt 15, 16 is a partition plate B that partitions the inside of the drying chamber 3 into front and back parts, and has a hole 17 in the center through which the drum 5 is inserted. A seal member 18 is attached around the drum 5 and seals between the hole 17 and the drum 5.

Reference numeral 19 denotes a partition plate C that partitions the inside of the recovery chamber 4 into front and rear parts, and has a communication hole A20 in the lower part. 21
is a communication hole B, 22 provided in the front side of the partition plate B16 and the partition plate C19 in the partition plate A2.
23 is a fan casing partitioned on the rear side of the recovery chamber 4, 24 is a fan disposed inside this fan casing 23, and 25 is a fan 24. A rotating fan motor, 26 a suction port provided in the fan casing 23, 27 a discharge port, and 28 a communication pipe provided near the discharge port 27 on the rear surface of the recovery chamber 4; The inside and outside of the recovery chamber 4 (frame 1) are communicated with each other. 29 is a heater provided on the front side of the recovery chamber 4; 30 is a cooler provided between the fan 24 and the heater 29 in the recovery chamber 4;
It is la.

The operation will be explained based on this configuration.

Clothes that have been washed and dehydrated with a petroleum solvent by the dry cleaner are stored in the drum 5, and the fan motor 25, heater 29, and cooler 30 are driven. Then, drying air is circulated within the frame 1 by the fan 24 as shown by the solid arrow line. During this time, drying air heated by the heater 29 is introduced into the drying chamber 1, exchanges heat with the clothes, evaporates the solvent, and removes the vaporized solvent contained in the air after the heat exchange. Condensed in cooler 30,
Heat it again with the heater 29.

By providing the communication pipe 28 in the dry air circulation path, the downstream side of the fan 24 communicates with the outside of the machine, and the circulation path, that is, the air flow, is connected to the outside of the machine.
The inside of the system 1 has a negative pressure characteristic, and the door 11 and the input port B10
Pressure is applied between the two and the bearing 7 as indicated by the dotted arrow line. Therefore, drying air will not leak out from this part.

On the other hand, a small amount of outside air is sucked from this part due to the negative pressure, and that amount is discharged outside the machine from the communication pipe 28, but the amount is so small that there is no problem.

FIG. 2 shows another embodiment, in which the partition plate B
In place of the seal structure between the seal member 16 and the seal member 17, an air
A seal structure 31 is adopted.

That is, instead of the partition plate B16, 32 to 34 are three annular grooves provided adjacent to each other around the drum 5, and 35 is provided on the upper surface of the frame 1, and the annular groove 32 A fan chamber 36 communicates with the inside of the fan chamber 35, and a fan device 36 is provided in the fan chamber 35.

When the fan device 36 is driven, the fan chamber 3
5 into the annular grooves 32 and 34 at both ends, and is sucked in from the annular groove 33 in the center. Therefore, the air generated by the fan device 36 circulates from the annular grooves 32 and 34 at both ends to the annular groove 33 in the center, and an air seal structure is formed in this portion.

In this embodiment, the rotation of the drum 5 is not inhibited as compared to the previous embodiment in which the seal member 18 is brought into sliding contact with the partition plate B16.

[0019]

[Effect of the invention] In the structure of the clothes dryer of the present invention,
With a simple configuration, the seal structure of the door portion etc. can be simplified and costs can be reduced.
