[0045] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0046] It should be noted that in the description of the present invention, the terms indicating directions or positional relationships such as "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the accompanying drawings. This is only for convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0047] Referring to Figures 1 - 6 , an embodiment of the washing machine viewing window of the present invention is applied to a drum washing machine. The drum washing machine includes a housing, an outer tub and an inner tub. The washing machine viewing window is hinged to the outer tub of the housing. As Figure 1 shown, the washing machine viewing window includes an outer frame 100, a glass cover 200, a window gasket 300, a window screen 500 and a decorative ring 400.

[0048] The outer frame 100 is hingedly connected to the outer tub of the washing machine. The glass cover 200 is disposed at the rear side of the outer frame 100.

[0049] As Figure 3 shown, the window gasket 300 includes a front insertion portion 310, a rear insertion portion 320 and a lip portion 330 located at the rear side of the rear insertion portion 320. Slots are provided on both the front insertion portion 310 and the rear insertion portion 320. The front insertion portion 310 is sleeved on the inner edge of the outer frame 100 through the slot, and the rear insertion portion 320 is sleeved on the glass cover 200 through the slot. The lip portion 330 of the window gasket 300 abuts against the outer tub, causing elastic deformation of the lip portion 330, thereby playing a sealing role.

[0050] The decorative ring 400 is of an annular structure, is disposed at the front side of the outer frame 100, is pressed on the front insertion portion 310 of the window gasket 300, and is fixedly connected to the outer frame 100 through a first snap structure. The window gasket 300 and the outer frame 100 are fastened through the decorative ring 400.

[0051] For the above-mentioned washing machine viewing window, the assembly method between the glass cover 200, the window gasket 300, the outer frame 100 and the decorative member adopts a screwless design, with a simple production process and convenient installation and disassembly; at the same time, the window gasket 300 is integrated into the viewing window module. Compared with the case where the window gasket 300 is installed on the front panel, there is no need for a fastening ring for the window gasket 300, and no special tool is required for installation and disassembly, which is convenient for production and maintenance; the above-mentioned viewing window has no inner frame, glass pressing strip, screws and other structural parts, with fewer structural parts, low cost and a simple installation process.

[0052] In this embodiment, the first snap structure includes a plurality of first claws 410 and a plurality of first slots 131. As shown in Figure 5 , the first claws 410 are arranged on the rear side surface of the decorative ring 400 along the circumferential direction of the decorative ring 400. As shown in Figure 4 , the first slots 131 are formed on the outer frame 100. As shown in Figure 3 , the first claws 410 are correspondingly snap-fitted and fixed to the first slots 131. Specifically, as shown in Figure 4 , the outer frame 100 includes an annular outer frame body 110, an inclined wall 120 extending backward and inward along the inner side of the outer frame body 110, and an inner edge portion 130 extending inward from the inclined wall 120. The inner edge portion 130 is inserted into the front insertion portion 310 of the window gasket 300. The first slots 131 are formed on the inner edge portion 130 and are arranged close to the outside. When the inner side of the inner edge portion 130 is inserted into the front insertion portion 310 of the window gasket 300, the first slots 131 will not be blocked by the front insertion portion 310, so as to be snap-fitted and fixed to the first claws 410. When the decorative ring 400 is fixed to the outer frame 100, the outer edge of the decorative ring 400 abuts against the inclined wall 120 of the outer frame 100 to ensure no gap. In this embodiment, the first claws 410 are evenly distributed around the decorative ring 400. Correspondingly, the first slots 131 are evenly distributed along the inner edge portion 130 for one week.

[0053] In order to further enhance the assembly stability of the observation window, the decorative ring 400 and the window gasket 300 are fixedly connected through a second snap structure.

[0054] Specifically, referring to Figure 5 and Figure 6 , the inner edge of the decorative ring 400 is bent backward to form a flanging portion 430. The second snap structure includes a plurality of second claws 420 and a plurality of second slots. As shown in Figure 5 , the second claws 420 are arranged on the outer side surface of the flanging portion 430 of the decorative ring 400 along the circumferential direction; the second slots (not shown) are arranged on the inner side of the front insertion portion 310 of the window gasket 300. As shown in Figure 3 , the second claws 420 are correspondingly snap-fitted and fixed to the second slots.

[0055] Preferably, the second claws 420 are arc-shaped long claws protruding outward along the outer side surface of the flanging portion. Since the material of the window gasket 300 is a relatively soft material and is easy to deform, the second claws 420 are long claw structures, and the second slots are correspondingly long strip slots, which can increase the contact area between the two, improve the snap-fitting firmness of the second snap structure, and prevent deformation and falling off. Since the outer frame 100 and the decorative ring 400 are made of hard materials, the first claws 410 can therefore be short claw structures. For the convenience of installation and disassembly, the first claws 410 and the second claws 420 of the decorative ring 400 are arranged in a staggered manner.

[0056] In this embodiment, the window screen 500 is covered on the glass cover 200 and is pressed and fixed on the glass cover 200 through the end of the flanging portion 430 of the window gasket 300. That is, after the decorative ring 400 is snap-fitted and fixed to the window gasket 300 through the second snap structure, the flanging portion 430 of the decorative ring 400 presses the window screen 500 against the glass cover 200 at the same time.

[0057] The outer frame 100 is made of stainless steel. The stainless steel material has high strength, so there is no need to add structural parts such as an inner frame, and the installation process is simple. Moreover, since the outer frame 100 is made of stainless steel, a hinge structure can be directly provided on the outer frame 100. Specifically, there is a connecting portion on one side of the outer frame 100, and a hinged structure is provided on the connecting portion. The outer frame 100 is hinged to the outer tub of the washing machine through the hinge structure, and there is no need to provide a hinge plate, which reduces the structural parts and simplifies the installation process.

[0058] As Figure 1 shown, specifically, the hinge structure includes two hinges 610, and the hinges 610 are fixed to the outer frame 100 through round head bolts 620. Using the round head bolts 620 for connection can reduce the phenomenon of screw plug covers, which can not only save the installation space between the observation window and the washing machine housing, but also meet the appearance design requirements.

[0059] A handle mounting hole 140 is also provided on the outer frame 100 for mounting the observation window handle 700.

[0060] Referring to Figure 7 and Figure 8 , the present invention further includes a drum washing machine, which includes a housing, an outer tub and an inner tub disposed in the housing. The outer frame 100 of the washing machine observation window is hingedly connected to the outer tub. When the observation window is closed, the lip portion 330 of the window gasket 300 abuts against the outer tub 800 to achieve sealing.

[0061] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, for those of ordinary skill in the art, it is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions required to be protected by the present invention.
