Drum type washing drier

Abstract

The proposal of the invention is to provide a small-scale drum-type washing and drying device which can increase the reliability of the intensity of the pipeline connection part at the same time of reducing the vibration noise thereof. The invention comprises a rotary roller (29) which can be rotated optionally and provided with a rotating shaft transversely; an outer tank (20) used for surrounding the rotary roller (29) and storing the washing water; an outer frame (2) surrounding the outer tank (20) inside; and a drying device (6) comprising a dehumidifying part, a heater and a air-feeding fan which are used for feeding hot air into the rotary roller (29). At least part of the drying device (6) is arranged at the outer frame (2) side. The ventilation channel positioned at the drying device (6) side is connected with the outer tank (20) side so as to arrange a corrugated tube (7) in such a way that the flexible direction of the corrugated tube is along the front side of the outer tank or along the basically straight direction. The corrugated tube (7) is arranged at the external side of the external periphery at the front of the outer tank.

Description

technical field [0001] The present invention relates to a drum-type washing-drying machine equipped with a drying device equipped with a heat exchanger to perform washing, dehydration and drying. Background technique [0002] The drum-type washing and drying machine is described in Patent Document 1 (Japanese Unexamined Patent Publication No. 2005-224621, p. 7, figure 1 )middle. In this drum type washing and drying machine, the circulation air path is connected from the outlet of the heater to the side of the circular opening for taking out and putting in laundry. Patent Document 2 (Japanese Unexamined Patent Publication No. 2005-224351, p. 12, figure 2 ) of the drum-type washing-drying machine, the air outlet from the heater outlet is connected to the front of the outer tank through a gasket. [0003] In the washer dryer, in order to shorten the drying time, it is necessary to cool the dehumidification pipe to improve the dehumidification performance. Therefore, to kee...

AI Technical Summary

Problems solved by technology

[0004] In the structure of the prior art, since the circulating air path is connected from the outlet of the heater to the side of the circular opening for taking out and putting in the laundry, it is difficult to absorb the displacement caused by the vibration of the outer tank, especially the vibration in the front and rear directions of the outer tank, In order to improve the strength and reliability of the pipe connection, further efforts are required

In addition, when the air outlet from the heater outlet is connected to the front of the outer tank through a gasket, in order to absorb the vibration of the outer tank, the connecting part needs a necessary length, which is disadvantageous for the miniaturization of the drum type washing machine.
