[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
[0030] Please refer to Figure 1-2As shown in the figure, the utility model relates to a plastic handle structure of a refrigerator, which has an integrated display module 100 and a handle module 200. The overall cross-section of the display module 100 and the handle module 200 is rectangular. The display module 100 is located above the handle module 200. A rectangular installation groove is provided on the front side of the display module 100. A fixing mechanism is arranged in the installation groove. Through the fixing mechanism, the control panel 300 can be fixedly embedded into the installation groove. The specific structure of the fixing mechanism is not limited, as long as it can meet the purpose of fixing the control panel 300 in the installation groove. For example, in the embodiment of the present utility model, the fixing mechanism is a buckle and a clamping groove arranged on the bottom surface and the side wall of the installation groove. After the control panel 300 is placed in the installation groove, the control panel 300 can just be embedded into the installation groove, and is fixed through the buckle and the clamping groove, etc., and its outer surface presents a flat transition surface with the display module 100.
[0031] An outlet hole 101 is also provided at one end of the installation groove far from the handle module 200. A grounding groove 102 is also provided on the inner wall of the installation groove near the outlet hole 101. After the control panel 300 is installed in the installation groove, the wire harness of its pipeline passes through the outlet hole 101 and extends to the outside, and is grounded through the grounding groove 102.
[0032] Please refer to Figure 3 , the handle module 200 is composed of a bottom plate 201 and a handle 202 located at the inner end of the outer surface of the bottom plate 201. A finger receiving space is formed between the handle 202 and the bottom plate 201. The user's thumb is placed outside the handle 202, and the other four fingers are placed in the finger receiving space to pinch the handle 202, and force can be exerted to control the opening and closing of the refrigerator door. In order to make the user experience better when using the handle module 200, the opening width of the entrance end of the finger receiving space is set to 15.9 mm, and the opening width of the end point is set to 14.1 mm. The middle thickness of the handle 202 at the part where the thumb and the other four fingers exert force is about 7 mm, and the rear thickness is about 8.5 mm. This can not only meet the normal opening and closing operation of the door, but also does not affect the thickness of the foam layer of the door body condensation, and at the same time the user will not feel the thinness of the handle 202. A cavity is provided inside the handle 202 at the part where the thumb and the other four fingers exert force. The width of the cavity at the thinnest part is 2 mm, and the width of the cavity at the thickest part is 3.5 mm.
[0033] The bottom plate 201 is an inclined surface with an inclination angle of 4°. The outer side surface of the handle 202 is also an inclined surface with an inclination angle of 8°. The inclined surface treatment at these two places can reasonably increase the thickness of the foam layer inside the handle structure while taking into account the user experience. Considering the condensation problem of the handle structure, a gradual glue stealing treatment is carried out on the inner wall of the handle structure, and the gap with the highest point of the Ω groove of the door liner is 5.5 mm, ensuring the minimum thickness of the foam material. A protrusion is made on the inner side of the door liner correspondingly to ensure that the thickness of the foam layer is 35 mm, ensuring that there is no condensation on the large surface of the handle 202.
[0034] Please refer to Figure 4 , on the rear side of the handle structure, there are seven latches 400 and five claws 600 provided to fix the door shell and the handle structure; on the three sides where the handle structure mates with the door body, there are stiffeners 500 provided to control the gap between the door shell and the handle structure within 0.5 mm.
[0035] When installing this handle structure on the refrigerator door shell, there is a structure on the door shell that matches the installation of the handle structure, and the specific steps are as follows:
[0036] The first step: Tear off the release paper of the double-sided tape on both end faces of the handle structure;
[0037] The second step: Bend the two door shell stiffeners on the door shell outward to prevent the handle structure from scratching the front when rotating;
[0038] The third step: As shown in Figure 5-6 , tilt the handle structure at a certain angle, first insert the three claws 600 on the vertical side, then align the claws 600 at both ends, rotate slightly to ensure that the left end door shell is engaged with the latch 400, and then rotate the right end door shell into the gap of the handle structure. After basically entering, continue to rotate towards the door shell until the handle structure is completely fitted with the door shell surface. Finally, pull the handle towards the front of the human body once, and when you hear a click sound, it means that the handle structure is assembled in place with the door shell;
[0039] The fourth step: Bend the two door shell stiffeners bent in the second step in the reverse direction and press them on the latches 400 of the handle structure, and the installation of the handle structure is completed. The completed effect is as shown in Figure 7 ;
[0040] The fifth step: Install the control panel 300 into the installation slot of the display module 100, and the purpose of integrating the display function and the handle function in one place can be achieved.
