Embodiment 1

[0032] figure 1 It is a perspective view showing the appearance of the washing and drying machine of this embodiment.

[0033] Such as figure 1 As shown, the washing and drying machine S has a casing 1 constituting the outer contour. The box 1 includes left and right side panels 1a, 1b, a front cover 1c, and a rear cover 1d (refer to figure 2 ), the upper cover 1e, the front lower cover 1f and the base 1h. In addition, the left and right side panels 1a, 1b of the box body 1 are combined by a U-shaped upper reinforcement (not shown), a front reinforcement (not shown), and a rear reinforcement (not shown), including The base 1h is inside and has a box shape.

[0034] The door 9 which closes the inlet for loading and unloading laundry is provided in the approximate center of the front cover 1c. Moreover, the operation panel 6 provided with the power switch 39, operation switches 13 and 15, the display 14, etc. is provided in the center of the upper part of the front cover 1...

Embodiment 2

[0069] Next, Figure 12 The structure of the foreign matter trapping part 231 of Example 2 is shown. Figure 12 It is a figure which looked at the foreign matter trapping part 231 from above. and Figure 6 The point of difference is that the arrangement density of the protrusions 70 in the outer region 711 and the inner region 721 is different.

[0070] The arrangement density of the first protrusions 71 in the outer region 711 is higher than the arrangement density of the second protrusions 72 in the inner region 721 . That is, the interval at which the first protrusions 71 are arranged in the outer region 711 (the distance between the first protrusions 71 ) is smaller than the interval at which the second protrusions 72 are arranged in the inner region 721 (the distance between the second protrusions 72 ). )short.

[0071] According to this embodiment, the clogging of piping is suppressed by the second protrusions 72 having a low density, and the collection performance i...

Abstract

The present invention provides a drum-type washing machine having a filter case that suppresses reduction in detergency and trapping performance and improves cleaning performance. The drum-type washing machine includes a case, an outer case that is supported in the case in a vibration-proof manner, a rotating case that is rotatably supported in the outer case, a motor that rotationally drives the rotating case, a drain path that drains water from the outer case to the outside of the machine, and a foreign matter collection unit arranged on the way of the drain path for collecting foreign matters, wherein the foreign matter collection unit includes a plurality of protrusions for collecting foreign matters.

Description

technical field [0001] The present invention relates to a washing machine for washing clothes and the like. Background technique [0002] In Patent Document 1, the following structure is provided: an outer tank accommodates a rotatable inner tank and stores washing water, and a filter device captures washing water flowing out from the bottom of the outer tank. Containing foreign matter such as cilia generated from washing clothes, the filter device has a filter case and a filter that is detachably assembled to the filter case and traps foreign matter. In this form, by setting a barrier from the filter inlet to the filter The outlet of the water flow in the case drain path is dispersed in the dispersion wall portion provided in the collection and storage portion, so that the cilia and foreign matter discharged from the laundry can be efficiently collected. [0003] In Patent Document 2, a structure is provided in which a filter unit for collecting foreign substances is provi...
