Drum-type washer and dryer

Abstract

The present invention provides a drum-type washing and drying machine which can reliably prevent the intruding of washing foam generated in drum into the places of heating unit, air supplying unit, etc. which are concealed in an air supplying and heating channel at a state of overmuch foam generation. The drum-type washing and drying machine can respectively detect the overmuch foam generation through setting a first electrode (62) and a second electrode (64) which are used for detecting the foam generated in the washing course at a warm air supplying channel (61) homogeneous to the downstream side of air supplying and heating channel (67) and a dehumidifying unit (63) homogeneous to the upstream side, thereby reliably preventing the infusing phenomenon generated by the adhering of washing foam on the air supplying and heating channel (67) and an air supplying fan (66), and increasing the reliability of the heater and air supplying fan.

Description

technical field [0001] The invention relates to a drum-type washing and drying machine capable of completing various processes such as washing, rinsing, dehydration and drying in a drum with a rotating shaft in a horizontal or inclined state. Background technique [0002] Figure 4 and Figure 5 The structure of the conventional drum-type washer-dryer is shown in (for an example, refer to Japanese Patent Laid-Open No. 2006-136601). This structure will be described below. [0003] The cylinder 1 is in the shape of a bottomed cylinder, and the entire outer cylinder wall is provided with many water holes 2, which are installed in the water holding cylinder 3 in a freely rotatable manner. The motor 4 drives the drum 1 to rotate in forward and reverse directions. A plurality of protruding plates 5 are provided on the inner wall surface of the drum 1 . [0004] An opening is provided on the upwardly (rear) inclined front of the body positioned at the front side of the water st...

AI Technical Summary

Problems solved by technology

[0013] However, when the drum-type washer-dryer with the above-mentioned existing structure is performing washing operations, since the first pair of electrodes and the second pair of electrodes are in the warm air supply passage, when a large amount of washing foam is generated during the stirring process , the foam will immediately reach the second pair of electrodes, which will trigger the drainage operation, which will lead to problems such as prolonged washing time, low cleaning rate, and increased usage of washing water.

[0014] In addition, if the structure of the existing air supply heating channel is adopted, excessive washing foam may invade the dehumidification unit from the warm air inlet connected to the drum, and adhere to the air supply fan and heating device in the air supply heating channel. , causing problems of odor generation and reduced reliability
