Embodiment 1

[0040] see Figure 1 to Figure 6 , the invention provides a washing machine top cover, comprising a top cover frame 1 and a cover plate 3, the gap between the peripheral wall of the cover plate 3 and the top cover frame 1, and the surface of the cover plate 3 away from the washing machine barrel and the top cover The gaps between the frames 1 are all equipped with packing 2 with sealing performance, and the cover plate 3 and the roof frame 1 can be bonded together through the filler 2. The filler 2 is colloid, which not only makes the cover plate 3 and the top cover The connection between the cover frame 1 is firm, and the sealing performance is reliable at the same time, which avoids the occurrence of water or humid air entering the cross-section of the cover plate caused by the user or the external environment, causing the cover plate to swell due to moisture and deformation of the top cover, so that the top cover of the washing machine can Effective moisture-proof and water...

Embodiment 2

[0045] This embodiment provides a washing machine, which includes the top cover of the washing machine in Embodiment 1, and also includes a cylinder, and the top cover of the washing machine is installed on the upper end of the cylinder.

Embodiment 3

[0047] The present embodiment provides the bonding method of the washing machine top cover in embodiment 1, comprises the following steps:

[0048] Step A, use a glue gun to apply an appropriate amount of filler 2 to the inner wall 12 of the top cover frame 1 or the glue groove 4;

[0049] Step B, assembling the cover plate 3 and the top cover frame 1;

[0050] Step C, using tooling to perform preliminary pressing on the cover plate 3 and the top cover frame 1;

[0051] Step D, use a glue gun to apply an appropriate amount of colloidal filler to the assembly gap between the peripheral wall of the cover plate 3 and the top cover frame 1 .

[0052]The colloidal filler in the present invention is hot-melt adhesive, which is a kind of plastic adhesive. Within a certain temperature range, its physical state changes with the change of temperature, but its chemical properties remain unchanged. It is non-toxic and tasteless, and belongs to Environmentally friendly chemical products....

Abstract

The invention provides a washing machine top cover, a bonding method and a washing machine and relates to the washing machine technology field. In the prior art, a washing machine top cover frame is only bonded and sealed with the circumferential wall of a cover plate so that a flash seam is easy to generate. In the invention, the above technical problem is solved. The washing machine top cover comprises the top cover frame and the cover plate. A filling material having sealing performance is arranged in a gap between the circumferential wall of the cover plate and the top cover frame and a gap between the surface of the cover plate which is deviated from a washing machine drum and the top cover frame. The cover plate and the top cover frame can be bonded into one body through the fillingmaterial. In the invention, soundness between the top cover frame and the cover plate is increased, the flash seam between the cover plate and the top cover frame is avoided, and simultaneously, sealing performance is reliable, phenomena that the cover plate is damped and swelled and the top cover is deformed are avoided, the top cover of the washing machine is dampproof and waterproof, and the safety of the internal electric appliances of the washing machine is increased.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a washing machine top cover, a bonding method, and a washing machine. Background technique [0002] At first, the top cover structure of the washing machine was mostly connected by the top cover frame and the cover plate with nails. The defect of this structure is that there is a gap between the cover plate and the top cover frame. , water easily seeps into the inside of the washing machine from the above-mentioned gaps, threatening electrical safety. [0003] At present, the top cover frame and cover plate of the washing machine top cover are mostly assembled by reactive hot melt adhesive coating and bonding, and only the inner wall of the top cover frame and the surrounding wall of the cover plate are glued and sealed. The solid hot melt adhesive is heated to a certain temperature and becomes fluid. The fluid hot melt adhesive is applied by a glue gun to the position ...
