Drum-type washing and drying machine

Abstract

The invention relates to a drum-type washing and drying machine, comprising: a rotary drum with a rotary shaft; a water barrel which covers the rotary drum inside and elastically supports on a main body; a warm air generation section composed of a heating section and an air supply section both for drying washings; a circular air supply path communicated with the water barrel to guide the warm airto the water barrel; and a separator provided in the circular air supply path and opens and closes the circular air supply path by rotation. The separator is configured to be supported by the rotary shaft and incline toward a downstream side about the rotary shaft at a predetermined angle with respect to a flow of the warm air in the circular air supply path, so as to either enter into an openingstate by means of the warm air from the warm air generation section or enter into a closing state by means of a hammer mounted on the separator once the warm air stops being supplied, besides, the separator includes such a structure preventing foams of a detergent from backflow; a concave groove for mounting the hammer is provided at a lower surface of the separator at a upstream side from the rotary shaft, and a lower surface inclining face is provided in a direction of the lower end of the concave groove of the hammer from a front end at the upstream side.

Description

Technical field [0001] The invention relates to a drum-type washing and drying machine which performs washing, rinsing, dehydration and drying steps in a rotating drum. Background technique [0002] The structure of the existing drum-type washing and drying machine, for example, as disclosed in Japanese Patent Application Laid-Open No. 2000-93697 (Patent Document 1), usually uses a blower after washing and dehydrating operations in the drum. Air that has been turned into warm air by the heating device is introduced into the drum to dry the laundry. [0003] Also, as disclosed in Japanese Patent Application Laid-Open No. 2006-136511 (Patent Document 2), for example, a structure to prevent bubbles from entering is proposed so that detergent bubbles generated during washing do not enter the heating device and the air blowing device. , So there will be no insulation deterioration.

AI Technical Summary

Problems solved by technology

[0013] However, the structure of the warm air supply path of the drum type washer-dryer in the first conventional example has the following problem: a large amount of detergent foam generated in the rotary drum 105 will enter the warm air supply channel communicating with the inside of the rotary drum 105. route, and impregnated the air supply fan and warm air generating part, resulting in odor and reduced reliability

However, since the closing member 232 and the like are formed in the connection opening 231 of the circulating air supply path 224, there is a problem that the closing member mounting portion in the circulating air supply path 224, which is a relatively large component, must be configured with high precision, and the assembly work complicated issues
