Description

Washing machine

The present invention relates to a washing machine for washing clothes.

A conventional washing machine includes a washing tub that opens upward, a housing that houses the washing tub, and an operation panel that receives an operation request regarding the operation content of the washing machine. The housing includes a front wall facing the user and a ceiling wall formed with a slot for allowing clothes to be thrown into the washing tub. The top wall includes a front edge that forms a corner with the front wall, and a rear edge opposite to the front edge. The operation panel may be attached to the front wall of the top wall.

¡When the operation panel is attached to the front wall, it is necessary to design the distance between the front edge of the top wall and the insertion port to be longer in order to attach the operation panel. As a result, the inlet of the top wall is separated from the front wall. This may cause the user to feel inconvenient when putting clothes into the washing tub and / or taking out clothes from the washing tub. Furthermore, wet clothing moves across the area where the operation panel is arranged. As a result, the water or the like dripped from the clothing may cause an electrical failure in a circuit provided in the operation panel.

In order to solve the above problems, conventionally, a washing machine in which an operation panel is arranged near the rear edge of the top wall has been proposed (see, for example, Patent Document 1). And a laundry tub can be arrange | positioned near the front wall of a top wall by arrange | positioning an operation panel near the rear edge. Thus, the user can easily put the clothes into the washing tub and can easily take out the clothes from the washing tub.

However, the washing machine generally has a configuration in which a water supply port for supplying water to the washing tub is attached near the rear edge of the top wall. Therefore, when the operation panel is disposed near the rear edge of the top wall as in the washing machine described in Patent Document 1, a circuit or the like provided in the operation panel is electrically caused by water leakage at the water supply port. There was a problem that it was easy to cause a failure.

JP 2005-519712 A

The present invention provides a washing machine that is less likely to cause an electrical failure.

That is, the washing machine of the present invention cleans clothes. The washing machine accepts an operation request regarding the operation content of the washing machine, a casing including a top wall having a front edge and a rear edge opposite to the front edge, a cover member partially covering the top wall, and the washing machine A reception unit, and a water supply port for supplying water into the housing. The cover member has an opening that exposes the water supply port. The reception unit is attached to the cover member.

According to the above configuration, the cover member that partially covers the top wall is formed with the opening that exposes the water supply port. Therefore, the water leaking from the water supply port adheres to the cover member and / or the ceiling wall. At this time, since the reception unit is attached to the cover member, water attached to the cover member and / or the ceiling wall does not enter the reception unit. As a result, a washing machine that is less susceptible to electrical failure can be realized.
