Problems solved by technology

However, as an important part of the appearance design, the observation window of the drum washing machine is an important element of the appearance design. In the trend of appearance design, the diameter design of the observation window is getting larger and larger, and the front plate is likely to cause strength loss after being rounded. Therefore, it is necessary to solve the strength reliability problem in the design process of the ultra-thin observation window embedded in the front plate

Embodiment 1

[0041] like figure 1 and Figure 4 As shown, the back side of the front plate 1 described in this embodiment is equipped with a first reinforcing plate 6 relative to the position of the hinge 7, which can effectively support the hinge 7 and can also strengthen the overall strength of the observation window; the inner frame 2 and A second reinforcing plate 8 is installed between the middle frame 4 and the corresponding position of the hinge 7, and the second reinforcing plate 8 is fixed on the inner frame 2, and the middle part of the inner frame 2 is installed with a glass basin 3, and the outer edge of the glass basin 3 is located on the inner frame 2. Between the inner frame 2 and the second reinforcing plate 8, the inner frame 2 and the second reinforcing plate 8 are fixed by connecting pieces such as bolts.

[0042] The first reinforcing plate 6 and the second reinforcing plate 8 are plate-shaped structures, the first reinforcing plate 6 and the hinge 7 are respectively f...

Embodiment 2

[0044] Figure 1 to Figure 3 As shown, the front plate 1 described in this embodiment is provided with an installation opening corresponding to the washing machine inlet, and the observation window is correspondingly installed in the installation opening. The circular groove 12 arranged on the outer periphery of the installation port, the inner frame 2 is installed inside the circular groove 12, and the outer periphery of the circular groove 12 is provided with a circle of outwardly protruding reinforcing ribs 11 to improve the rigidity of the front plate, so The reinforcing rib 11 protrudes from the surface of the front plate 1 toward the outer periphery of the circular groove 12 in an arc-shaped oblique upward direction, and the inclined surface is connected with the peripheral wall of the circular groove 12 in a smooth transition.

[0045]In this embodiment, the inner ring of the circular groove 12 is provided with an annular groove 13 that is recessed on the back of the fr...

Embodiment 3

[0048] See attached Figure 5 and Image 6 , the first reinforcing plate 6 described in this embodiment is detachably and fixedly installed on the back side of the front plate 1, which can enhance the rigidity of the front plate 1. The first reinforcement plate 6 forms an arc-shaped periphery on the side facing the installation port, and the side of the plate-shaped structure opposite to the arc-shaped periphery faces the same direction and is vertically bent twice to form a fixed part to improve stability. In particular, preferably, the first reinforcing plate 6 is a sheet metal part.

[0049] In this embodiment, the first reinforcing plate 6 includes a body 60 , a first bending surface 61 and a second bending surface 62 , the first bending surface 61 is parallel to the body 60 , and the two sides of the second bending surface 62 The side vertically connects the main body 60 and the first bending surface 61, and the connection between the first bending surface 61 and the se...

Abstract

The invention discloses an observation window installation structure, which comprises a front plate, the middle part of the front plate is provided with an installation opening for installing the observation window, and the front surface of the front plate is provided with a hole sunken toward the back and wrapped around the outer circumference of the installation opening. A circular groove, the observation window is rotatably installed inside the circular groove through a hinge, and a circle of outwardly protruding reinforcing ribs is provided on the outer periphery of the circular groove. The observation window in the present invention can be embedded in the circular groove of the front plate to improve the space utilization rate and protect the observation window from external impact and deformation during transportation. The outer circumference of the circular groove is provided with reinforcing ribs, which improves the stability of the front plate. overall rigidity.

Description

technical field [0001] The invention belongs to the field of household appliances, and in particular relates to an observation window installation structure. Background technique [0002] The clothes inlet of the existing drum washing machine is provided with an observation window, which is connected to the front plate of the drum washing machine through a hinge, which not only plays a role of sealing the washing machine to prevent the water in the drum from overflowing, but also helps the user to check the clothes in the drum. Observe the laundry condition. However, as an important part of the appearance design, the observation window of the drum washing machine is an important element of the appearance design. In the trend of appearance design, the diameter design of the observation window is getting larger and larger, and the front plate is likely to cause strength loss after being rounded. Therefore, it is necessary to solve the strength reliability problem in the desig...
