Washing machine

Abstract

A washing machine that is provided with: a casing (2); a rotating drum (4) that has a rotational central axis (12) that, from the front of the casing (2) toward the rear, is horizontal or downwardly inclined, and that has a rotating drum opening (4a) provided to the front thereof; and a water tank (1) that houses the rotating drum (4) such that the latter can rotate in both directions, and that is provided with a water tank opening (1a) that is positioned so as to face the rotating drum opening (4a) along the rotational central axis (12). The washing machine is also provided with: a control unit (14) that executes a washing operation that includes a washing step, a rinsing step, a spin step, etc.; and a gap opening (7) that is formed over the entire circumference and that is constituted by a gap that is between a front end (4b) of the rotating drum opening (4a) and a rear end (1b) of the water tank opening (1a). In addition, a covering surface (28) is provided inside the water tank to an outer-circumferential side of the gap opening (7) across the entire circumference thereof. In at least one circumferential-direction part thereof, the covering surface (28) has an inclined part that is inclined in the circumferential direction toward the inner-circumferential side.

Description

technical field [0001] The present invention relates to a washing machine that washes laundry thrown into a rotary drum by rotationally driving the rotary drum disposed in a water tank. Background technique [0002] use Figure 9 and Figure 10 A conventionally proposed washing machine will be described. Figure 9 It is a longitudinal sectional view of a conventional washing machine (for example, refer to Patent Document 1). Such as Figure 9 As shown, rotary drum 105 having clothes inlet 125 at the front and water tank 103 accommodating rotary drum 105 are arranged in washing machine casing 102 so as to be inclined upward at an angle θ from the horizontal direction. The water tub 103 rocks up, down, left, and right along with the rotation of the rotary drum 105 during the washing and dehydrating operation. Therefore, water tub 103 is supported in the washing machine casing 102 in a vibration-proof manner so as to be free to swing. Washing machine casing 102 and water tan...

AI Technical Summary

Problems solved by technology

[0007] However, in the conventional washing machine described in Patent Document 1, there is still a gap between the covering member provided at the opening of the water tank and the opening of the rotary drum.

Therefore, it may not be possible to completely prevent clothing from entering the gap

Moreover, if the operation is continued with the clothes entering the gap, the clothes will be further stuck and hinder the rotation of the rotary drum.

As a result, the casing of the washing machine may vibrate greatly or operate abnormally to forcibly end

In addition, there is a problem that the clothes are caught in the depth direction of the gap due to centrifugal force, whereby the clothes cannot be taken out, or the clothes are damaged due to friction with the side of the sink

Therefore, it may not be possible to reliably prevent the laundry from flying out or being caught between the sink and the laundry return plate.
