Description

[Detailed Description of the Invention] Industrial Field of Application □ The present invention uses a corrugated thin plate as a blade, and directs high temperature drying circulating air 2 vanes and low temperature cooling air to both sides of the blade. The present invention relates to a dehumidifying type clothes dryer equipped with a heat exchange type blower that also performs heat exchange and removes all moisture in the circulating air for drying.

Structure of a conventional example and its problems A conventional clothes dryer of this type is as shown in FIG.
Configure clothing storage. 3 is the impeller of heat exchange type blower F, which is a corrugated thin plate with grooves located radially. - It is mainly configured and rotates under the rotational force of the motor 4, thereby pumping drying circulating air on one side and pumping cooling air on the other side. In the figure, a indicates the flow direction of the above-mentioned circulating air. The dry air flows through a dry air path consisting of, etc.

In the figure, b indicates water distribution in the flow direction of the cooling air, and the dryer body 1
Air is sucked in through the rotation of the impeller 3 from the back side of the dryer 3, and is discharged outside the main body 1 of the dryer 3 through the grooves of the impeller 3.

Reference numeral 8 denotes a drain port connected to one part of the circulation exhaust wind cylinder 6, 9kj, a front door for opening and closing the bII surface opening of the rotating drum 2, and 10 a heating wind cylinder in which the heater 7 is housed. ,
11 is a cooling side casing.

In the above configuration, during heat exchange between the circulating air guided by the heat exchange blower F and the cooling air, moisture in the circulating air condenses, and the condensed water is discharged from the drain port 8 to the outside of the machine. is discharged to. At this time, a large amount of dew condensation can be seen all over the inner wall of the circulating exhaust wind cylinder 6.

In addition, in an atmosphere with a temperature of 20'C and a humidity of 60%,
” - When the dehumidifying type dryer described above is operated at full capacity, the crystallinity difference between the cooling air discharged from the heat exchange blower F and the circulating air is 6°C even after heat exchange is performed in the heat exchange blower F.
~8°C. 1. To summarize the above,
The heat exchange action in the heat exchange blower F is not necessarily sufficient, and the circulating air that passes through the circulating exhaust wind cylinder 6 and reaches the heater 7 contains moisture, which is heated by the heater Y. If it is fed into the rotating drum 2, it will naturally cause problems in terms of drying performance.

OBJECTS OF THE INVENTION The present invention solves the two conventional problems and aims to efficiently remove moisture from circulating drying air from a heat exchange type blower to a heater side.

DESCRIPTION OF THE INVENTION In order to achieve the object, the present invention particularly includes a circulating air path from a circulation side casing of a heat exchange type blower to a heating element (heater), and provides cooling of the heat exchange type blower. By providing a cooling exhaust wind barrel that guides the cooling air discharged from the side casing to the outside of the dryer main body, it is possible to eliminate the considerable temperature difference between the circulating air and the cooling air after heat exchange. The cooling air is used to cool the circulating air from the circulation side casing to the heating element, and the humidity is extremely low at the stage where the circulating air is heated by the heating element.
The drying efficiency is increased by pumping circulating air containing almost no moisture into the clothes storage.

DESCRIPTION OF EMBODIMENTS The present invention will be described in detail from page 6 onwards. In FIGS. 2, 3, and 4, the same reference numerals as those in FIG. 1 indicate members having the same functions, and therefore the description thereof will be omitted.

In FIG. 2, the circulating exhaust wind cylinder 6 constitutes a part of the dry air path. It is enclosed in a substantially cylindrical cooling exhaust wind cylinder 12 for cooling. That is, the cooling air to be exhausted flows between the outer surface of the circulating exhaust wind cylinder 6 and the inner surface of the cooling exhaust wind cylinder 12,
The internal circulating air is further cooled through the wall surface of the circulating exhaust wind cylinder 6, thereby causing condensed water on the inner surface of the circulating exhaust wind cylinder 6. This condensed water flows down along the tapered surface and is discharged from the drain port 8 to the outside of the machine.

3 and 4 show another embodiment of the present invention, in which a cooling exhaust wind barrel 12 guides exhaust air from the cooling side casing 11.
'W, it is formed by airtightly partitioning one corner of the dryer main body 1 with a partition wall 13. In this case, the cooling exhaust wind cylinder 12' includes six pages of the circulation exhaust wind cylinder 6. Also in this configuration, the second
As shown in the figure, moisture in the circulating air can be removed within the circulating exhaust wind cylinder 12'. In particular, in the configurations shown in Figures 3 and 4,
Since the cross-sectional opening area of the cooling exhaust air cylinder 12' can be increased, the amount of cooling air increases and the dehumidification performance improves.

Effects of the Invention According to the present invention, attention is paid to the fact that there is a considerable temperature difference between the circulating air discharged from the heat exchange type blower and the cooling air even through heat exchange with the heat exchange type blower, and the cooling air is By this, the circulating air inside a part of the dry air path is continuously cooled and moisture is removed, and the dehumidification performance can be further improved by the air blowing pressure of the heat exchange type blower itself.
