Embodiment approach 1

[0018] figure 1 It is a schematic diagram which shows the internal structure of the washing-drying machine 100 which concerns on Embodiment 1 of this invention. exist figure 1 In the case, the outer tank 2 is elastically supported in the housing 1 through a shock absorber (not shown). A bottomed cylindrical rotary drum 3 is rotatably installed in the outer tank 2 , and the axial direction of the rotary drum 3 is substantially arranged in the horizontal direction (including the horizontal direction). Outer tank 2 is arranged along the periphery of rotary drum 3 .

[0019] On the front side of the outer tank 2, a clothes inlet 4 communicating with the opening end of the rotary drum 3 is formed, and laundry 5 can be put into and taken out from the rotary drum 3 through the clothes inlet 4. A driving device 6 such as a motor is provided on the back side of the outer tank 2, and the rotating drum 3 is rotationally driven in the forward direction and the reverse direction by th...

Embodiment approach 2

[0038] figure 2 It is a schematic diagram which shows the internal structure of the washing-drying machine 200 which concerns on Embodiment 2 of this invention. In the present embodiment, in the main drain path 8 , a first return trap 9 for storing water drained out of the washing and drying machine 200 is provided on the downstream side of the drain valve 7 . The drain path 20 of the heat exchanger is connected to the first water return bend 9 , and the first water return bend 9 and the second water return bend 22 form an integrated return water bend. The other configurations are the same as those of the first embodiment, and the same reference numerals are assigned to the same configurations, and the detailed description refers to the description of the first embodiment.

[0039] According to the above structure, the second water return trap 22 can also be used as the first water return trap 9 , and the washing water and drying air discharged from the outer tank 2 can be p...

Embodiment approach 3

[0041] image 3 It is a schematic diagram which shows the internal structure of the washing-drying machine 300 which concerns on Embodiment 3 of this invention. In the present embodiment, the second return trap 22 is arranged on the upstream side with respect to the lift portion 23 in the heat exchanger drain path 20 . The other configurations are the same as those of the first embodiment, and the same reference numerals are assigned to the same configurations, and the detailed description refers to the description of the first embodiment.

[0042] According to the above structure, even when the washing water discharged from the outer tank 2 is drained, the washing water will not intrude into the second return water bend 22, so the inside of the heat exchanger drainage path 20 can be kept clean, and the drainage can be prevented more reliably. clogged.

[0043] In addition, the heat exchanger drain path 20 may be connected to the outer tank 2 other than the main drain path 8...

Abstract

A washing and drying machine, comprising: an outer tank (2) elastically supported in a casing (1); a rotary drum (3) rotatably disposed in the outer tank (2); a main drainage path (8), which is used to discharge the water in the outer tank (2) to the outside of the housing (1); a drain valve (7), which is used to open and close the main drainage path (8); and a dehumidification part (14), which for dehumidifying the drying air to be supplied into the rotary drum (3); a heating part (15) for heating the air dehumidified in the dehumidifying part (14); a casing (16) for A dehumidification part (14) and a heating part (15) are accommodated; a water sprinkler (18) is used to remove foreign matter adhering to the dehumidification part (14); The heat exchanger drain path (20) and the drain pump (21) are used to discharge the water sprayed from the sprinkler (18) from the housing (16), and the heat exchanger drain path (20) is provided with a drain for accumulating water from the housing (16). ) the second water return bend (22) of the discharged water and the lifting part (23) which is higher than the washing water level during washing.

Description

technical field [0001] The present invention relates to a washing and drying machine capable of washing and drying clothes and the like. Background technique [0002] Conventional washing machines and so-called washer-dryers equipped with a drying function can continue to dry laundry such as washed clothes in the same tank. [0003] In the drying process, drying air is blown into the rotary drum while stirring the laundry in the rotary drum. Moist air for drying that comes into contact with wet clothes is cooled and dehumidified by the dehumidification unit, and then heated by the heating unit to become dry warm air that circulates. In this way, laundry such as laundry is dried. [0004] As the laundry is dried, lint such as lint tends to be generated from the laundry or the like. The lint separated from the clothes etc. is mixed with the air for drying and adheres to the air blower, heat exchanger, etc. provided in the circulating air duct, which causes the deteriorating...
