[0028] Unless otherwise specified, the orientations or positional relationships indicated by “length”, “up”, “down”, “front”, “back”, “top” and “bottom” are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present application and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0029] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. In addition, "connected" should be understood in a broad sense, and may include fixed connection, detachable connection, or integral connection; it may be mechanical connection or electrical connection.

[0030] It should also be noted that, for the convenience of introduction, Figure 1 The straight line where y is located is the front-to-back direction, and the direction of the arrow along the y direction points forward. The straight line where z is located is the up-down direction, and the direction of the arrow along the z direction points upward. The object is placed along the z direction, its upper surface is the top surface, and the lower surface is the bottom surface. The straight line direction where x is located is the extension direction of the boss 110, which is also the sliding direction of the door body 12, and also the length direction of the door body 12.

[0031] like Figure 1 、 Figure 2As shown, the present application provides a freezer 1, comprising a cabinet body 11 and a door body 12. A boss 110 is provided on the top of the cabinet body 11, and the door body 12 can be slidably provided on the boss 110 along the extension direction of the boss 110, as shown in FIG. Figure 3 As shown, the refrigerator 1 further includes a roller 13 , which is rotatably disposed on the boss 110 . The roller 13 can contact the door body 12 and can rotate relative to the door body 12 . The door body 12 is in contact with the boss 110 and can slide on the boss 110 along the extension direction of the boss 110. The door body 12 in the prior art is completely fitted with the boss 110. The completely fitted door body 12 and the boss 110 generate greater friction due to the large contact area, so that a greater force is required to push the door body 12 to make the door body 12 slide on the boss 110. In order to reduce the force for pushing the door body 12, a roller 13 is provided on the boss 110. The reduced contact area between the roller 13 and the door body 12 can reduce the friction. In addition, the roller 13 can also rotate on the boss 110. When the door body 12 needs to be pushed and pulled, after a certain force is applied to the door body 12, the door body 12 drives the roller 13 to rotate. Afterwards, the roller 13 can also drive the door body 12 to move during the rotation process, thereby reducing the force applied to the door body 12 while ensuring that the door body 12 slides smoothly on the boss 110.

[0032] In one embodiment, if Figure 1 As shown, the boss 110 includes a first boss 111 and a second boss 112 that are parallel to each other. The first boss 111 is provided at the first end 11a of the top of the cabinet 11, and the second boss 112 is provided at the second end 11b of the top of the cabinet 11. The first end 11a of the top of the cabinet 11 is higher than the second end 11b of the top of the cabinet 11. The first boss 111 is provided with a roller 13. The first end 11a of the top of the cabinet 11 is higher than the second end 11b of the top of the cabinet 11, that is, the second boss 112 provided at the first end 11a of the top of the cabinet 11 is higher than the first boss 111 provided at the second end 11b of the top of the cabinet 11. Figure 1 The height H2 of the second boss 112 shown in FIG is higher than the height H1 of the first boss 111. At this time, the door 12 installed on the top of the cabinet 11 is in an inclined state (eg Figure 7 As shown), the friction between the door body 12 and the first boss 111 is greater than the friction between the door body 12 and the second boss 112. Therefore, when the second boss 112 is higher than the first boss 111, the roller 13 is provided on the first boss 111 to reduce the contact area between the first boss 111 and the door body 12 ( Figure 8It is shown in the figure that after the roller 13 is set, the roller 13 contacts the door body 12, and the door body 12 does not directly abut the first boss 111, thereby reducing the contact area between the door body 12 and the first boss 111), thereby reducing the friction between the door body 12 and the first boss 111, and then reducing the force required to be applied to the door body 12, ensuring that a smaller force applied to the door body 12 can push the door body 12 to slide on the cabinet body 11.

[0033] It should be noted that the roller 13 can be set only on the first boss 111, or on the second boss 112. Of course, the roller 13 can also be set on both the first boss 111 and the second boss 112. The above is not restrictive and can be set according to the needs of technical personnel in this field. The above are all within the protection scope of this application.

[0034] In one embodiment, if Figure 1 、 Figure 4 As shown, the door body 12 is arranged to be arc-shaped so that the middle part of the door body 12 is recessed toward the cabinet body 11. At this time, when the door body 12 is recessed toward the cabinet body 11, the center of gravity of the door body 12 moves further toward the first boss 111, thereby increasing the friction between the door body 12 and the first boss 111. At this time, arranging the roller 13 on the first boss 111 can further reduce the force applied to the door body 12, thereby allowing the user to easily push the door body 12.

[0035] It should be noted that if Figure 7 、 Figure 8 As shown in the figure, since the door body 12 is tilted and recessed toward the middle of the cabinet body 11, when the freezer 1 is set on the ground, the connection between the door body 12 and the cabinet body 11 is not horizontal. In order to ensure that the roller 13 and the door body 12 are surface-supported rather than line-supported, at this time, the position where the roller 13 is connected to the door body 12 is perpendicular to the door body 12. At this time, the roller 13 is not perpendicular to the ground, but has a certain inclination angle. In order to better support the roller 13, the surface of the first boss 111 supporting the roller 13 is perpendicular to the roller 13. Therefore, the surface of the first boss 111 supporting the roller 13 is also not parallel to the ground, that is, there is a certain inclination angle.

[0036] In one embodiment, if Figure 4As shown, the door body 12 is provided with a first slide 121 parallel to the first boss 111. The first slide 121 corresponds to the roller 13 on the first boss 111, so that the roller 13 can contact the first slide 121 and can rotate relative to the first slide 121. The provision of the first slide 121 can ensure that the roller 13 on the first boss 111 always moves on the first slide 121. At the same time, the first slide 121 and the roller 13 can also cooperate and limit. The cooperation between the first slide 121 and the roller 13 guides the movement of the door body 12, ensuring that the door body 12 moves along the extension direction of the first boss 111, that is, the x-direction, and prevents the door body 12 from tilting during movement.

[0037] In one embodiment, if Figure 3 、 Figure 5 、 Figure 6 As shown, the refrigerator 1 further includes a sealing strip 14, which is disposed in the first slideway 121. The door body 12 can slide to a first position. Figure 2 The position of the door body 12 shown in the figure is the first position. In the first position, the door body 12 closes the cabinet body 11 , and the sealing strip 14 is sealed and connected to the first boss 111 . Figure 2 In the figure, a door 12 is shown as an example for description. The door 12 slides to the first position, i.e., the position of sealing the cabinet 11. Figure 3 for Figure 2 The door body 12 and the first boss 111 and the second boss 112 are disassembled schematically. At this time, the sealing strip 14 is schematically attached to the first boss 111. Figure 3 It can be seen in the figure that when the door body 12 is in the first position, the first boss 111 of the door body 12 corresponds to the sealing strip 14, and the sealing strip 14 can ensure the sealing of the freezer 1 to prevent the freezer 1 from leaking cold.

[0038] In one embodiment, if Figure 3 As shown, combined with Figure 2 When the door body 12 is in the first position, a plurality of rollers 13 may be provided, and two of the plurality of rollers 13 are correspondingly provided at both ends of the length direction of the door body 12. Figure 2 The roller 13 in the middle is covered by the door body 12, and the roller 13 is located at the corner of the door body 12. If a certain force is applied to the door body 12 in the first position, the two rollers 13 rotate synchronously. At this time, the user can easily push the door body 12 to slide.

[0039] It should be noted that when multiple rollers 13 are provided on the first boss 111, there can be two rollers 13, that is, they are correspondingly provided at both ends of the length direction of the door body 12. Of course, there can also be three or more. In addition to the rollers 13 correspondingly provided at both ends of the door body 12, the other rollers 13 are provided between the rollers 13 at both ends. The number of the above rollers 13 is not restrictive and can be set according to the needs of technical personnel in this field. The above are all within the protection scope of this application.

[0040] In one embodiment, if Figure 6 As shown, the second boss 112 is provided with rollers 13 at both ends along the length direction of the door body 12, and the rollers 13 of the second boss 112 and the first boss 111 can form a rectangle. Figure 5 The box in the figure is a rectangle surrounded by four rollers 13. The provision of rollers 13 on both the first and second bosses 111, 112 can further reduce the force required to push the door body 12. Furthermore, when the rollers 13 on the first and second bosses 111, 112 form a rectangle, the rollers 13 on the same side of the first and second bosses 111, 112 simultaneously contact or disengage with the door body 12, thereby ensuring that the door body 12 is always balanced on the first and second bosses 111, 112.

[0041] In one embodiment, if Figure 4 、 Figure 5 、 Figure 6 As shown, the door body 12 is further provided with a second slide 122 . The second slide 122 contacts the roller 13 of the second boss 112 and rotates relative to it. The second slide 122 and the first slide 121 are symmetrically arranged on the door body 12 . Figure 4 In the middle, 12a is the symmetry axis 12a of the first slide 121 and the second slide 122. Since the rollers 13 on the first boss 111 and the second boss 112 can be surrounded by a rectangle, at this time, the rollers 13 on the first boss 111 and the second boss 112 are symmetrical, and the first slide 121 and the second slide 122 are also symmetrical. The above arrangement can ensure that the door body 12 is relatively uniformly stressed along the length direction of the door body 12, i.e., the x-direction, thereby ensuring the stability of the relative rotation when the roller 13 contacts the door body 12 and the stability of the door body 12 set on the cabinet body 11.

[0042] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
