Abstract

A panel of washing or dewatering machine, which includes a surrounding frame and a transparent cover arranged in the center thereof. A mounting position for a controlling knob is placed on the surrounding frame. The transparent cover is rotatablely fixed on the surrounding frame by a shaft bearing mechanism. The whole transparent cover is in spherical coronal shape and the edge of which is a round arc. Due to the spherical coronal-shaped configuration of the whole cover, the concentrated pressure stress is eliminated by the whole spherical surface so that strength of the cover can be substantially increased, and under the same pressure a thinner material can be used for the cover so that the resource is saved and the cost is reduced, and furthermore compared to other covers made from same material,this cover can bear greater pressure so that it is non-frangible and has a longer service life.

Description

Washing machine, dehydrator panel

The invention relates to a panel of a household appliance, in particular to a washing machine and a dehydrator panel. Background technique

In a household appliance product such as a single-tub washing machine or a dehydrator, a panel is disposed on an upper portion of the main body of the product, and the panel includes a surrounding frame and a cover plate disposed at a frame portion, wherein the enclosure has a control switch knob disposed thereon Most of the mounting parts are made of transparent material, and the shaft support mechanism can be turned over with respect to the surrounding frame. At present, the design of the above-mentioned cover plate is mostly as shown in FIG. 15 and FIG. 16, that is, the edge of the cover plate in FIG. 15 is substantially rectangular, and the central portion has a curved transparent window that protrudes outward. A digging ring placed along a curved transparent window is mounted on the cover: In order to avoid interference with the control switch knob, the cover plate in Fig. 16 is designed as a straight edge at the edge of the cover plate close to the control switch knob. That is to say, the edge of the cover plate in the above two panels has a straight edge structure. In actual use, after a certain pressure is applied to the cover plate, the stress tends to concentrate on its straight side area, and as a result, the edge of the cover plate is easily broken. Furthermore, in Fig. 15, in order to smoothly engage with other parts of the cover plate, the convex height of the curved transparent window is generally not too obvious, so that the strength of the cover plate is further reduced. ^: : ' In Figure 16, the appearance of a large straight edge breaks the feel of the entire circle of the cover, and the formation of a large-area oblique transition surface also weakens the strength of the cover and has the drawback of poor visual effect. :' Invention content

The technical problem to be solved by the present invention is to provide a washing machine and a dehydrator panel which are excellent in strength and are not easily broken, in view of the above-mentioned state of the art.

The technical solution adopted by the present invention to solve the above technical problem is as follows: the washing machine and the dehydrator panel comprise a surrounding frame and a transparent cover plate disposed on the frame portion, wherein the surrounding frame has an installation for arranging a control switch knob The transparent cover plate is inverted relative to the frame by the shaft support mechanism, and the transparent cover plate has a spherical crown shape as a whole, so that the edge of the transparent cover plate forms a circular arc structure.

Preferably, the mounting portion is located on a central axis of the frame and is a circular platform, and the transparent cover is provided with an arc-shaped recess corresponding to the circular platform, such that It avoids the interference between the transparent cover and the control switch knob, and at the same time maximizes the diameter of the edge of the transparent cover plate, and the structure is symmetrical, so that the strength of the transparent cover plate is better.

A transitional slope of the arc-shaped recess and the surface of the transparent cover may be disposed at the same center as the circular platform, thereby preventing stress concentration at the portion, and at the same time making the transition slope occupy the entire transparent cover. The area is minimized to maintain the strength of the transparent cover.

In the above aspects, in order to further increase the strength of the transparent cover, the transparent cover is away from the

- 1 - Confirmation The edge of the arc-shaped recess is fixed with a reinforcing ring, that is, the reinforcing ring opening at this time, and the reinforcing ring may have a flange opposite to the arc-shaped concave portion to form a hand-carrying portion for holding by the hand. 4吏The reinforcing ring and the digging hand ring are combined into one, and the overall structure is more compact. The above-mentioned flange can be designed as an inner flange and an outer flange, that is, when the flange is extended upward along the surface of the transparent cover, it is an inner flange, and the surface of the transparent cover corresponding to the inner flange can have a recessed portion allows the hand to have a larger space for easy gripping; when the flange is extended upwardly toward the surface of the transparent cover, it is an outer flange, and the structure keeps the transparent cover The complete spherical crown structure, with better strength, also facilitates the opening of the transparent cover.

When the arc-shaped recess is not designed on the transparent cover, the reinforcing ring can be fixed on the entire edge of the transparent cover, that is, the reinforcing ring has an annular structure. Similarly, the reinforcing ring can have a cuff to form a hand-dug portion for holding the hand, so that the reinforcing ring and the digging hand ring are combined into one, and the overall structure is more compact. At this time, the flange can be designed as an inner flange and an outer flange. When the flange is extended upward along the surface of the transparent cover, it is an inner flange, and the surface of the transparent cover corresponding to the inner flange can have a recessed portion, in the same way, by means of the recessed portion, the hand can be inserted into the space to have a larger space for the grip; when the flange is extended upwards toward the surface of the transparent cover, it is an outer turn. The structure allows the transparent cover to maintain a relatively complete spherical crown structure with better strength and easy opening of the transparent cover.

Compared with the prior art, since the transparent cover plate of the present invention is integrally designed as a spherical crown structure, the overall spherical structure can be utilized to eliminate the stress concentration problem after the pressure, which can obviously improve the strength of the transparent panel, and even Under pressure, the transparent panel can select a relatively thin material to save resources and reduce cost. For a transparent cover made of the same material, the invention can withstand greater pressure, making it less fragile and prolonging use. life. Moreover, since the height of the spherical cap is no longer limited by other parts of the transparent cover, the height of the spherical crown can be correspondingly designed to be higher, so as to further increase the strength of the panel, it can also provide a float to the consumer. The visual impact is to help improve the grade and competitiveness of the product. DRAWINGS
