[0032] The technical solutions in the embodiments (or "implementations") of this application will now be clearly and completely described with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.
[0033] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.
[0034] Please see Figure 1 and Figure 2 This application provides a refrigeration unit 2, including a unit housing 20 and a refrigeration component 27. The refrigeration component 27 is disposed inside the unit housing 20. Sliding mating portions 21 extending gradually upwards from front to back are provided on opposite sides of the exterior of the unit housing 20.
[0035] This application provides sliding mating portions 21 on opposite sides of the outer casing 20 of the unit, with the sliding mating portions 21 extending upwards gradually from front to back, so as to... Figure 3 When the refrigerator body 1 shown is slidably fitted, the refrigeration unit 2 can be gradually slid upwards from front to back to the bottom of the body 1, providing different assembly options for the refrigeration unit 2.
[0036] Please see Figure 3 In one embodiment, the refrigerator body 1 has an opening 10 on its front side. The body 1 includes two side panels 11 located on opposite sides of the opening 10 and a rear panel 12 disposed opposite to the opening 10. The inner sides of both side panels 11 are provided with sliding portions 111 that gradually extend upward from front to back, and the sliding portions 111 are slidably engaged with the sliding mating portions 21.
[0037] In one embodiment, the sliding fit portion 21 includes a slide rail, the width of which gradually decreases from front to back. Alternatively, the sliding fit portion 21 includes a slide groove, the width of which gradually increases from front to back.
[0038] During the sliding process of the refrigeration unit 2 relative to the refrigerator body 1 from front to back, the rear part of the sliding mating part 21 provided on the side of the unit outer shell 20 should first mate with the front part of the sliding part 111 provided on the body 1. When the sliding mating part 21 is set as a slide rail, by setting the width of the slide rail to gradually decrease from front to back, the end with the smaller width at the rear of the slide rail can be inserted first into the sliding part 111 provided on the body 1, such as the slide groove, thereby reducing the insertion accuracy of the rear of the slide rail and improving the assembly efficiency of the slide rail and the slide groove. When the sliding mating part 21 is set as a slide groove, by setting the groove width to gradually increase from front to back, the sliding part 111 provided on the body 1, such as the slide rail, can be inserted first into the end with the larger width at the rear of the slide groove, thereby reducing the insertion accuracy of the slide rail and improving the assembly efficiency of the slide rail and the slide groove.
[0039] Please see Figure 1 and Figure 4 In one embodiment, the outer casing 20 of the unit is further provided with side abutment members 22 on opposite sides for abutting against the side panels 11 of the refrigerator. The side abutment members 22 are located above the sliding mating part 21. Thus, by tightly fitting the side abutment members 22 of the refrigeration unit 2 against the side panels 11 of the refrigerator, the cold air inside the refrigerator and the heat generated by the refrigeration unit 2 can be prevented from being transferred to each other through the gap between the side panels 11 and the refrigeration unit 2, thereby achieving mutual isolation between their respective spaces.
[0040] Please continue reading. Figure 1 and Figure 4In one embodiment, the side abutment member 22 includes an abutment protrusion extending outward from the outer surface of the unit housing 20. The abutment protrusion has a side abutment surface 222 formed on the side opposite to the sliding mating part 21. Thus, the side abutment surface 222 can abut against the refrigerator's side panel 11 in the vertical direction, forming a seal between the refrigeration unit 2 and the refrigerator's side panel 11 in the vertical direction to prevent cold leakage. Exemplarily, the side abutment surface 222 is arranged parallel to the horizontal plane; or, the angle formed between the side abutment surface 222 and the horizontal plane is smaller than the angle formed between the sliding mating part 21 and the horizontal plane. This avoids the side abutment surface 222 having an excessively large tilt angle that could interfere with the sliding process of the refrigeration unit 2.
[0041] Please continue reading. Figure 4 In one embodiment, the abutment protrusion also forms a vertical abutment surface 221 on the side facing away from the unit housing 20, and the vertical abutment surface 221 is arranged perpendicular to the horizontal plane. Thus, the vertical abutment surface 221 can abut against the side panel 11 of the housing 1 in the left-right direction, so that the refrigeration unit 2 forms a seal with the side panel 11 of the housing in the left-right direction to prevent cold leakage.
[0042] Please see Figure 5 The side panel 11 of the housing is further provided with an inwardly protruding boss 112, which is located above the sliding part 111. The side abutment surface 222 abuts against the lower end surface 1121 of the boss 112, and the vertical abutment surface 221 abuts against the inner side wall of the side panel 11 below the boss 112. This allows for multi-directional sealing between the refrigeration unit 2 and the side panel 11.
[0043] Please continue reading. Figure 1 In one embodiment, reinforcing structures 28 are further provided on opposite sides of the outer casing 20 of the unit, and the reinforcing structures 28 are connected to the side abutment members 22. This improves the structural strength of the side abutment members 22. Exemplarily, the reinforcing structure 28 includes a plurality of reinforcing ribs spaced apart along the length of the side abutment members 22. Of course, the specific implementation of the reinforcing structure 28 is not limited to this.
[0044] Please continue reading. Figure 1 and Figure 4 In one embodiment, a rear abutment member 23 is further provided on the rear side of the outer casing 20 of the unit for abutting against the rear panel 12 of the refrigerator body. This forms a seal between the refrigeration unit 2 and the rear panel 12, preventing cold leakage. In one embodiment, the rear abutment member 23 includes a rear abutment surface 231 arranged parallel to the horizontal plane. This facilitates abutment against the lower wall surface 121 of the rear panel 12.
[0045] Please continue reading. Figure 2 In one embodiment, the refrigeration assembly 27 includes a compressor 271, a condenser 272, and an evaporator 273. The refrigeration unit 2 also includes a heat insulation component 274. The heat insulation component 274 is inclined upwards and backwards within the unit housing 20 to divide the interior of the unit housing 20 into a top space 275 and a bottom space 276. The top space 275 accommodates the evaporator 273, and the bottom space 276 accommodates the compressor 271 and the condenser 272. Thus, by using the heat insulation component 274 to divide the interior space of the unit housing 20, the refrigeration unit 2 can be more integrated and miniaturized.
[0046] For example, such as Figure 1 and Figure 2 As shown, the unit housing 20 includes a base 201 and a top cover 202, which together enclose a receiving space 316 for accommodating the refrigeration unit 2. Sliding mating portions 21 extending gradually upwards from front to back are provided on opposite sides of the base 201. Of course, the structural composition of the unit housing 20 is not limited to this.
[0047] In addition, the aforementioned insulation component 274 can be a plate-like structure, including but not limited to foam board or one-piece molded VIP board (vacuum insulation panel).
[0048] In one embodiment, a metal strip 24 is provided on the bottom front side of the unit housing 20 for fitting against the refrigerator door seal 312. In another embodiment, a hinge mounting portion 25 is also provided on the bottom front side of the unit housing 20 for mounting the refrigerator door 31 hinge. Exemplarily, the hinge mounting portion 25 and the metal strip 24 are located at opposite ends on the bottom front side of the unit housing 20.
[0049] It should be noted that after the refrigeration unit 2 is installed with hinges, and the refrigerator door 31 is rotatably connected to the refrigeration unit 2 via the hinges, since the door 31 is also rotatably connected to one side of the cabinet 1, the hinges and the door 31 can prevent the refrigeration unit 2 from retracting.
[0050] Please continue reading. Figure 1 and Figure 2 In one embodiment, the refrigeration unit 2 further includes a control component disposed inside the unit housing 20. The control component includes a control plate 26 disposed at the bottom of the unit housing 20, near the sliding mating member. This avoids occupying the central area inside the unit housing 20 and affecting the assembly space of other components.
[0051] Please see Figure 6This application also provides a refrigerator, including the refrigeration unit 2 described in any of the above claims.
[0052] This application provides different assembly schemes for the refrigeration unit 2 by providing sliding mating parts 21 on opposite sides of the outer casing 20 of the unit, and the sliding mating parts 21 gradually extend upward from front to back. When the refrigerator body 1 is slidably mated, the refrigeration unit 2 can gradually slide upward from front to back to the bottom of the body 1, which provides different assembly schemes for the refrigeration unit 2.
[0053] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
