[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 4 .

[0027] The front windshield of the refrigerator of the utility model comprises a windshield body 1 and four first flanges 2 respectively arranged around the windshield body 1 in the horizontal direction, and at least one of the first flanges 2 is provided with at least one gourd hole 201 in the horizontal direction, the gourd hole 201 is provided with a step screw 3, and the step portion of the step screw 3 can pass through the large hole portion 2011 of the gourd hole 201, and the small diameter portion 302 of the step screw 3 can slide into the small hole portion 2012 of the gourd hole 201 to achieve fixation.

[0028] When the front wind shield of the refrigerator of the utility model is used, it is only necessary to install the corresponding step screws 3 on the refrigerator. The gourd hole 201 and the step screw 3 are inserted and slidably matched to achieve quick disassembly operation. The structure is simple, and the gourd hole 201 is a punching operation. No additional components are added except the step screw 3, and the production cost is low. At the same time, the gourd hole 201 is opened in the horizontal direction, so that the wind shield body 1 moves in the horizontal direction during installation, thereby maintaining the overall aesthetics of the refrigerator. In the present embodiment, the gourd hole 201 and the step screw 3 are realized by the large diameter portion 301 of the step screw 3 being clamped at the two sides of the small hole portion 2012 of the gourd hole 201 corresponding to the first flange 2.

[0029] In one embodiment, see Figure 4 , a limiting groove 202 connected to the gourd hole 201 is also provided at the position of the first flange 2 corresponding to the gourd hole 201, and the groove width of the limiting groove 202 can just accommodate the large diameter portion 301 of the corresponding step screw 3. With this design, the limiting groove 202 can prevent the step screw 3 from moving in the vertical direction after the step portion of the step screw 3 penetrates the large hole portion 2011 of the gourd hole 201, making it difficult for the small diameter portion 302 of the step screw 3 to align with the entrance of the small hole portion 2012 of the gourd hole 201. It should be noted that when the large diameter portion 301 of the step screw 3 passes through the large hole portion 2011 of the gourd hole 201, the side surface of the large diameter portion 301 of the step screw 3 is against the groove walls on both sides of the limiting groove 202.

[0030] In one embodiment, see Figure 5-6 , and further includes a guide member 4 disposed on the wind shield body 1, the guide member 4 is provided with a guide plate 5, and the guide member 4 can be slidably matched with the guide plate 5 to achieve alignment of the large diameter portion 301 of the step screw 3 with the large hole portion 2011 of the corresponding gourd hole 201. In this design, the guide member 4 and the guide plate 5 solve the problem that the gourd hole 201 is located on the inner side of the wind shield body 1, the position cannot be observed during installation, and the alignment is difficult.

[0031] In one embodiment, see Figure 6The guide plate 5 includes a guide portion 501 and an L-shaped limiting portion 502 connected to the guide portion 501, and the length of the guide plate 5 can meet the requirements of the step portion of the step screw 3 entering the large hole portion 2011 of the gourd hole 201 and the small diameter portion 302 of the step screw 3 is aligned with the entrance of the small hole portion 2012 of the gourd hole 201, and the width difference between the guide portion 501 and the limiting portion 502 meets the sliding length of the step screw 3 in the small hole portion 2012 of the gourd hole 201, and the guide member 4 is composed of two guide blocks 401 arranged at intervals, and the interval between the two guide blocks 401 can just accommodate the guide portion 501. With such a design, when the wind shield body 1 needs to be installed, the guide part 501 is first inserted between the two guide blocks 401. At this time, the step part of the step screw 3 is just aligned with the large hole part 2011 of the gourd hole 201. By sliding the wind shield body 1 along the length direction of the guide plate 5, when sliding to the bottom, the step part of the step screw 3 just passes through the large hole part 2011 of the gourd hole 201, and then slides to the position of the length difference between the guide part 501 and the limiting part 502. When sliding to the bottom, the step screw 3 just slides into the small hole part 2012 of the gourd hole 201 to be fixed, and cooperates with the limiting groove 202 to realize multi-directional limiting, which is convenient for the alignment installation of the gourd hole 201 and the step screw 3.

[0032] In one embodiment, see Figure 6 The guide plate 5 and the wind shield body 1 can also be connected by hand screws 6. With this design, when the guide plate 5 is installed on the refrigerator, it can be ensured that the wind shield body 1 is still assembled stably when it vibrates violently.

[0033] In one embodiment, see Figure 5 The windshield body 1 includes a ventilation plate 101 and four second flanges 102 extending longitudinally around the edges of the ventilation plate 101, and the four first flanges 2 are respectively arranged on the four second flanges 102. In this design, the longitudinal depth of the ventilation plate 101 is increased by the second flanges 102, which facilitates the installation of the filter 9.

[0034] In one embodiment, see Figure 2 and Figure 7, and also includes two groove bodies 7 respectively arranged on both sides of the ventilation plate 101, each of the groove bodies 7 includes a first shielding strip 701 arranged on one side close to the ventilation plate 101 and two L-shaped plates 702 respectively arranged at both ends of the first shielding strip 701, and the vertical parts of the two L-shaped plates 702 are arranged opposite to each other. With this design, the filter screen 9 can be disassembled and assembled between the L-shaped plates 702 at both ends of the two groove bodies 7 through the shielding effect of the first shielding strip 701. The specific disassembly process is to lift the filter screen 9 from the position where the filter screen 9 is located at the interval between the two groove bodies 7. After the filter screen 9 is lifted, the bottom of the filter screen 9 is separated from the L-shaped plate 702 located below, and then the filter screen 9 is deflected outward. Otherwise, the installation can be realized. In this embodiment, the height of the vertical part of the upper L-shaped plate 702 is approximately equal to twice the height of the vertical part of the lower L-shaped plate 702, so as to realize convenient disassembly and assembly.

[0035] In one embodiment, see Figure 7 The inner sides of the transverse parts of the two L-shaped plates 702 are also respectively provided with elastic pads 703. This design plays an elastic limiting role on the filter screen 9 to prevent the filter screen 9 from coming out due to equipment vibration.

[0036] In one embodiment, see Figure 7 The groove body 7 further includes a second shielding strip 704 disposed outside the transverse portion of the two L-shaped plates 702, and the second shielding strip 704 is integrally formed with the first shielding strip 701. This design cooperates with the L-shaped plate 702 to limit the filter screen 9 around and prevent the filter screen 9 from falling out.

[0037] In one embodiment, see Figure 1 At least one shock-absorbing pad 8 is also provided on the first flange 2. This design can further prevent the wind shield body 1 from generating noise with the refrigerator or the frame of the refrigerator, and in this embodiment, the shock-absorbing pad 8 can be attached to the first flange 2 by adhesive.
