[0028] The technical solutions in the embodiments (or, “modes of implementation”) of the present application will be described clearly and completely below with reference to the accompanying drawings. If there are terms related to direction or position relationship (such as up, down, front, back, inside, outside, top, bottom, length, width, etc.) in the embodiments of the present application, such terms are only used to explain the relative position relationship, movement condition, etc. between components in a certain posture (as shown in the drawings).
[0029] The present application provides a cabinet opening assembly for bearing a door 3 of a freezer, which is combined with Figure 1 , Figure 2 and Figure 3 , Figure 1 is a schematic diagram of a freezer, Figure 2 is a schematic diagram of a freezer with the door removed, Figure 3Is the local section view of the boss. The cabinet 1 is provided with a cabinet opening 2. The door body 3 covers the cabinet opening 2. The cabinet opening assembly is used to carry the door body 3. The cabinet opening assembly includes a boss 4, the door body is relative to the boss 4 sliding, the part of the boss 4 in sliding contact with the door body 3 includes a first extrusion part 41, the friction coefficient of the first extrusion part 41 is less than 0.2. The boss 4 is extruded, in the forming process, different raw materials may be extruded, after forming, part of the structure of the boss 4 is extruded by the same material, the commonly used material in sliding contact with the door body is polyvinyl chloride material (PVC), and the friction coefficient of polyvinyl chloride material (PVC) is 0.2-0.4. This part is called the first extrusion part 41. The friction coefficient of the first extrusion part 41 is less than the commonly used friction coefficient, the part of the boss 4 in sliding contact with the door body 3 includes the first extrusion part 41 with smaller friction coefficient, which can make the sliding friction force of the door body 3 relative to the boss 4 smaller, the sliding process more smooth, and reduce the wear between the door body 3 and the boss 4, improve the durability of the freezer.
[0030] In an embodiment, the first extrusion part 41 is a Teflon extrusion part. That is, part of the raw material of the boss 4 uses Teflon material in the forming process. Teflon material, also known as polytetrafluoroethylene, has low friction coefficient and wear resistance. It can further reduce the sliding friction force between the door body 3 and the boss 4, and further reduce the friction loss.
[0031] In an embodiment, the friction coefficient of the first extrusion part 41 is 0.04-0.1, for example, it can be 0.04, 0.06, 0.08, 1, etc. The commonly used material in sliding contact with the door body is polyvinyl chloride material (PVC), and the friction coefficient of polyvinyl chloride material (PVC) is 0.2-0.4. The friction coefficient of the first extrusion part 41 of the embodiment is 0.04-0.1, which is much smaller than that of polyvinyl chloride material (PVC), so the embodiment can significantly reduce the friction between the door body 3 and the boss 4, the process of sliding the door body 3 is more smooth, and the friction damage is smaller.
[0032] Combination Figure 1 And Figure 2The application also provides an ice cabinet, comprising the cabinet opening assembly and a cabinet body 1, the cabinet body 1 is provided with a cabinet opening 2, the cabinet opening 2 comprises a first side edge 21 and a second side edge 22 arranged oppositely, the first side edge 21 is higher than the second side edge 22. Here refers to the height in the normal use state of the ice cabinet. A door body 3 is arranged obliquely on the cabinet opening 2 and slides relative to the first side edge 21 and the second side edge 22, and the second side edge 22 is provided with the cabinet opening assembly. Since the door body 3 is arranged obliquely, the second side edge 22 will bear a large pressure due to gravity, so the second side edge 22 is provided with the cabinet opening assembly with a small friction coefficient and high wear resistance, and the friction damage of the second side edge 22 in the sliding process of the door body 3 is small.
[0033] In another embodiment, the first side edge 21 is also provided with the cabinet opening assembly. In this way, the friction damage of the first side edge 21 in the sliding process of the door body 3 is small.
[0034] In the embodiments of the application, the terms "first", "second", etc. are used only for the purpose of description and should not be understood as indicating or implying relative importance. In the embodiments, the terms "left", "right", "front", "back", "top", "bottom", "inside", "outside", etc. are used only for the purpose of description and should not be understood as indicating or implying relative importance. Figure 1 、 Figure 3 and Figure 4 , Figure 4 is a partial view of the ice cabinet without the door body. The door body 3 is an arc-shaped structure protruding towards the inside of the ice cabinet. The design of the concave door body makes the door body 3 more visually prominent. Due to the focusing effect of the concave surface on light, the customer's line of sight can be naturally focused and directed to the inside of the ice cabinet. This design not only improves the overall aesthetics of the ice cabinet, but also displays the goods in a larger visual angle, attracting the attention and interest of customers. The boss 4 comprises a first side surface 401 and a first bottom surface 402, the first side surface 401 is in sliding contact with the side surface of the door body 3, the first bottom surface 402 is in sliding contact with the rectangular edge of the bottom surface of the door body 3, and the first extrusion part 41 is located between the first side surface 401 and the first bottom surface 402.
[0035] Taking the cabinet door assembly located on the second side 22 as an example, the surfaces of the boss 4 and the door body 3 that slide in contact with each other are the first side surface 401 and the first bottom surface 402. The first bottom surface 402 needs to bear the weight, and the door body 3 is also an inclined concave structure, so the side of the door body 3 always keeps in contact with the first side surface 401. During the sliding process, the door body 3 will wear down due to sliding friction against the first side surface 401 and the second bottom surface 402. Teflon material also has good wear resistance and chemical resistance, so in this embodiment, the first extrusion part 41 is located on the first side surface 401 and the first bottom surface 402, which can reduce the wear caused by long-term use of the freezer and improve the service life of the freezer. Taking the first extrusion part 41 located on the first side surface 401 as an example, during the extrusion molding process, the boss 4 controls the placement of the Teflon material and the PVC material, thereby controlling the first extrusion part 41 to be located on the first side surface 401. The surface of the first extrusion part 41 is also part of the surface of the first side surface 401, and it contacts the door body 3.
[0036] In one embodiment, combined with Figure 5 and Figure 6 , Figure 5 This is a cross-sectional diagram of the boss. Figure 6 This is a cross-sectional view of the end of the door. The rectangular edge of the bottom surface of the door 3 has a recessed area 31, the width of which is the same as the width of the first bottom surface 402. The boss 4 extends along the edge of the cabinet opening 2, and similarly, the first bottom surface 402 and the first side surface 401 are also included. Therefore, the width of the first bottom surface 402 refers to... Figure 3 As indicated by the double-headed arrow x in the cross-sectional view, the rectangular recess of the clearance portion 31 fits precisely into the first bottom surface 402, ensuring that the side of the door 3 abuts against the first side surface 401. During the installation of the door 3 into the cabinet opening 2, the clearance portion 31 helps in the positioning of the door 3 and the boss 4, making the installation more convenient and efficient.
[0037] In one embodiment, the clearance portion 31 is provided with a first protrusion 311, and the door body 3 slides against the first bottom surface 402 through the first protrusion 311. Compared with the entire bottom surface of the clearance portion 31 sliding in contact with the first bottom surface 403, the contact area of sliding contact in this embodiment is small, and the sliding friction is small, thereby reducing the wear and tear on the protrusion 4 during the sliding process of the door body 3.
[0038] In one embodiment, the area of the first extrusion portion 41 located on the first side surface 401 is larger than the area of the side surface of the door body 3. This ensures that the entire sliding contact surface of the side surface of the door body 3 is located within the first extrusion portion 41, reducing lateral sliding friction. The width of the first extrusion portion 41 located on the first bottom surface 402 is greater than the width of the first protrusion 311. This ensures that the first extrusion portion 41 can cover the entire sliding contact surface. Here, width refers to... Figure 3 The direction indicated by the double-headed arrow x in the cross-sectional view.
[0039] In one embodiment, the width of the first extrusion portion 41 located on the first bottom surface 402 is 1.2 to 7 times the width of the first protrusion 311, specifically 1.5 times, 2 times, 4 times, 5 times, 7 times, etc. The width of the first protrusion 311 refers to the contact surface between the first protrusion 311 and the first bottom surface 402. Figure Three The dimension in the direction of the double-headed arrow. During the sliding process of the door 3, the first protrusion 311 may be... Figure Three The first extrusion part 41 moves in the direction of the double-headed arrow, so the width of the first extrusion part 41 in this embodiment is much larger than the width of the first protrusion 311, which can ensure that the first protrusion 311 always falls on the first extrusion part 41 and ensures smooth sliding.
[0040] Combination Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of the door unfolding. Figure 8 This is a schematic diagram of the sliding door. Along the length of cabinet opening 2 ( Figure 7 (in the direction of the double-headed arrow y), the door body 3 includes at least a first door body 301 and a second door body 302. The first door body 301 and the second door body 302 may slide relative to each other. Figure 8 The location is shown. There is a height difference between the two doors to allow for relative sliding, and they overlap. (Combined) Figure 6 The protrusion 4 also includes a first protrusion 411 and a second protrusion 412 corresponding to the first door 301 and the second door 302. The first door 301 slides on the first protrusion 411, and the second door 302 slides on the second protrusion 412. The first protrusion 411 and the second protrusion 412 are of the same length as the cabinet opening. The first door 301 or the second door 302 can slide to any position at the cabinet opening.
[0041] In another embodiment, the first boss 411 and the second boss 412 are stepped. The first boss 411 includes a side surface and a bottom surface, and the second boss 412 also includes a side surface and a bottom surface. The bottom surface of the first boss 411 is connected to the side surface of the second boss 412, so that the boss 4 is stepped.
