Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment, and in particular to a freezer. Background Technology

[0002] Currently, based on their refrigeration principles, freezers are generally divided into direct-cooling freezers and air-cooling freezers. Direct-cooling freezers are prone to frost buildup during use, while air-cooling freezers are favored by users because they have the advantage of being frost-free.

[0003] In related technologies, by connecting the evaporator cover to the inner liner, the storage compartment can be divided into an evaporation chamber and a storage chamber. The cold air generated in the evaporation chamber is transported to the storage chamber by an evaporation fan, thereby achieving air cooling of the storage chamber. However, since the evaporator cover and the inner liner are only connected by a fastener, a gap will be generated between them. This can easily lead to leakage between the evaporator cover and the inner liner, potentially causing localized overcooling in the storage chamber and affecting the air cooling effect of the freezer.

[0036] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0037] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0038] It should be understood that terms such as "upper," "lower," "outer," and "inner," used herein to indicate spatial relative position, are for illustrative purposes to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms "spatial relative position" may be intended to include different orientations of the equipment in use or operation other than those shown in the figures.

[0039] The device may be oriented in other ways (rotated 90 degrees or otherwise), and the spatially related descriptive terms used herein shall be interpreted accordingly. For ease of description, in the present invention, when the freezer is in normal use, the direction facing the ground is downward, and the direction away from the ground is upward; the direction parallel to the ground is horizontal, and the direction perpendicular to the ground is vertical; the side closer to the user is the front side, and the side farther from the user is the rear side.

[0040] refer to Figures 1 to 11 As shown, an embodiment of the present invention provides a freezer, which is configured as a horizontal air-cooled freezer.

[0041] like Figure 1 As shown, a freezer includes a cabinet body 1 and a door body, wherein the door body is connected to the top of the cabinet body 1.

[0042] In some embodiments, the door is pivotally connected to the top of the cabinet 1, allowing the user to open or close the receiving compartment from the top of the cabinet 1 for retrieval and placement operations. The pivot hinge connecting the cabinet 1 and the door may be located at the rear of the top of the cabinet 1.

[0043] In some embodiments, the freezer also includes a refrigeration system, which includes a compressor, a condenser, a capillary tube, an evaporator, etc. These components are connected by pipes to form a refrigeration circuit, and the cooling capacity generated by the evaporator can provide cooling for the storage compartment.

[0044] Reference Figure 2 As shown, the cabinet 1 includes an inner liner 11 forming a receiving chamber 111, an outer shell 12, and an insulation cavity 13 formed between the inner liner 11 and the outer shell 12.

[0045] In some embodiments, the accommodating chamber 111 is formed by an inner liner 11, which may be integrally molded, for example, by injection molding.

[0046] In other embodiments, the inner liner 11 may also be formed in parts, such as by splicing together components of the same or different materials.

[0047] In some embodiments, by filling the insulation cavity 13 with insulation material, the accommodating chamber 111 is insulated, thereby reducing heat exchange with the external environment.

[0048] Cabinet 1 includes evaporator cover 14.

[0049] In some embodiments, the evaporator cover 14 is connected to the inner liner 11. The evaporator cover 14 is located within the receiving chamber 111.

[0050] The evaporation cover 14 divides the receiving chamber 111 into an evaporation chamber 1111 and a storage chamber 1112.

[0051] In some embodiments, an evaporator and / or an evaporation fan are provided in the evaporation chamber 1111. Users can place the items they wish to store in the storage chamber 1112.

[0052] Reference Figures 3 to 7 As shown, cabinet 1 also includes at least one docking structure (15, 16, 17).

[0053] In some embodiments, the cabinet 1 may be provided with only one or more docking structures (15, 16, 17). As the number of docking structures (15, 16, 17) increases, the limiting strength and sealing performance between the evaporator cover 14 and the inner liner 11 can be improved.

[0054] The docking structures (15, 16, 17) are used to allow the evaporator cover 14 to be inserted into the inner liner 11.

[0055] In some embodiments, the docking structures (15, 16, 17) can also position the evaporator cover 14 and the inner liner 11 for docking (i.e., mutual insertion), making it easier for the evaporator cover 14 to be installed in the inner liner 11.

[0056] The freezer includes seals (2, 3, 4) that correspond one-to-one with the docking structures (15, 16, 17).

[0057] In some embodiments, the first docking structure 15 is provided with a first sealing element 2, the second docking structure 16 is provided with a second sealing element 3, and the third docking structure 17 is provided with a third sealing element 4.

[0058] The sealing element (2, 3, 4) is connected to either the evaporator cover plate 14 or the inner liner 11.

[0059] In some embodiments, the seals (2, 3, 4) are connected to the evaporator cover 14 or the inner liner 11 and can be assembled together with the evaporator cover 14 or the inner liner 11.

[0060] The sealing element (2, 3, 4) abuts against the other of the evaporator cover plate 14 and the inner liner 11 along the insertion direction of the mating structure.

[0061] In some embodiments, the sealing elements (2, 3, 4) abut against the evaporator cover plate 14 or the inner liner 11 along the insertion direction, so that after the evaporator cover plate 14 and the inner liner 11 are mated, the sealing elements (2, 3, 4) can be subjected to a force from the insertion direction (e.g., the clamping force of the fastener), thereby improving the sealing effect.

[0062] In this embodiment, the insertion directions of the multiple docking structures (15, 16, 17) can be at least partially the same.

[0063] In this embodiment, when the evaporator cover 14 and the inner liner 11 are connected by a mating structure (15, 16, 17), the sealing elements (2, 3, 4) also seal the gap between the evaporator cover 14 and the inner liner 11 along the mating direction, thereby avoiding local overcooling in the storage cavity 1112 and improving the air-cooling effect of the freezer.

[0064] The inner liner 11 has a clearance step 112 that protrudes toward the receiving compartment 111.

[0065] In some embodiments, the housing 12 has a compressor compartment 121 located below the clearance step 112, and the compressor and / or condenser are located within the compressor compartment 121.

[0066] The evaporation cover plate 14 and the clearance step 112 are arranged in a horizontal direction.

[0067] In some embodiments, compared to the arrangement of "evaporation cover 14 and clearance step 112 arranged in a vertical direction", evaporation cover 14 and clearance step 112 arranged in a horizontal direction can increase the available space at the top of storage cavity 1112.

[0068] In other embodiments, the evaporation cover 14 and the clearance step 112 are arranged in a vertical direction.

[0069] In some embodiments, the evaporation cover 14 and the clearance step 112 are arranged adjacent to each other, which can eliminate the gap between the evaporation cover 14 and the clearance step 112 and increase the usable space of the storage cavity 1112.

[0070] For example, such as Figure 2 The clearance step 112 is located at the right end of the bottom of the inner liner 11, and the evaporator cover 14 is located at the left end of the clearance step 112.

[0071] In some embodiments, the evaporator cover 14 and the clearance step 112 together form a step-like structure inside the inner liner 11, which facilitates the placement of items and makes it easier for users to clean the items at the bottom, thereby making reasonable use of the internal space of the storage cavity 1112.

[0072] The cabinet 1 includes a first docking structure 15.

[0073] In some embodiments, the first mating structure 15 enables the evaporator cover 14 and the clearance step 112 to be inserted into each other.

[0074] The first docking structure 15 includes a first docking block 151 disposed on one of the evaporation cover plate 14 and the clearance step 112, and a first docking groove 152 disposed on the other of the evaporation cover plate 14 and the clearance step 112.

[0075] In some embodiments, the first docking block 151 is disposed on the evaporator cover plate 14 and the first docking groove 152 is disposed on the clearance step 112, which can reduce the manufacturing difficulty of the inner liner 11 and facilitate the manufacturing of the first docking structure 15.

[0076] For example, such as Figure 3 The first docking block 151 is configured as a rib structure protruding from the end face of the evaporation cover plate 14 along the first direction, and the first docking groove 152 is configured as a groove structure recessed into the relief step 112 along the first direction.

[0077] The first docking block 151 and the first docking groove 152 are inserted and engaged along the first direction.

[0078] In some embodiments, the first docking structure 15 can position the docking between the evaporator cover plate 14 and the relief step 112, so that the evaporator cover plate 14 can overlap the relief step 112 and be fixed.

[0079] In this embodiment, after the first docking block 151 and the first docking groove 152 are inserted and engaged, the offset between the evaporation cover plate 14 and the clearance step 112 can be restricted. For example, the offset between the evaporation cover plate 14 and the clearance step 112 along a third direction can be restricted.

[0080] In this embodiment, after the first docking block 151 and the first docking groove 152 are inserted and engaged, the sealing between the evaporator cover plate 14 and the clearance step 112 can also be improved.

[0081] For example, the first direction could be Figure 1 The vertical direction in the middle, the third direction is Figure 1 The left and right directions in the middle.

[0082] The evaporation cover plate 14 includes a first docking portion 141 connected to the first docking block 151.

[0083] In some embodiments, in conjunction with reference Figure 8 As shown, the first docking block 151 protrudes from the lower end face of the first docking portion 141.

[0084] For example, the first docking portion 141 may be the right edge of the top plate 148 of the evaporation cover 14.

[0085] The first docking groove 152 is recessed into the upper end face 1121 of the clearance step.

[0086] In some embodiments, when the inner liner 11 is manufactured by one-piece molding (e.g., vacuum forming), the top end face of the entire relief step 112 is flush with the top end face 1121 of the relief step, which is the top end face of the relief step 112.

[0087] In other embodiments, such as Figure 4 When the inner liner 11 is configured as a separate unit, for example, it is formed by inserting an evaporator base plate 115 into a surrounding plate (116, 117). In this case, the upper end face 1121 of the step can be the top end face of the insertion groove 118 provided on the evaporator base plate 115.

[0088] At least a portion of the first docking block 151 extends into the first docking groove 152.

[0089] In some embodiments, after the first docking block 151 extends into the first docking groove 152, it can contact or be spaced apart from the bottom wall of the first docking groove 152, which can reduce the amount of gas leakage between the evaporation cover plate 14 and the clearance step 112 at the first docking structure 15 and improve the sealing performance of the evaporation chamber 1111.

[0090] The first docking portion 141 covers at least a portion of the upper end face 1121 of the clearance step.

[0091] In some embodiments, such as Figure 3 After the first docking block 151 extends into the first docking groove 152 along the first direction, the first docking part 141 covers a part of the upper end face 1121 of the relief step, making it difficult for gas to leak from the first docking part 141 and the upper end face 1121 of the relief step, thereby improving the sealing performance of the evaporation chamber 1111.

[0092] The yielding step 112 includes a yielding groove 1122 recessed in the upper end face 1121 of the yielding step.

[0093] In some embodiments, the clearance groove 1122 is located below the upper end face 1121 of the clearance step.

[0094] The yielding step 112 includes a first mating groove 152 recessed in the bottom surface 11221 of the yielding groove.

[0095] In some embodiments, such as Figure 4 The first docking groove 152 is located below the relief groove 1122. Thus, a multi-step structure with successively rising steps is formed between the bottom surface of the first docking groove 152, the bottom surface of the relief groove 11221, and the upper surface of the relief step 1121.

[0096] The bottom surface of the groove (e.g., the bottom surface of the relief groove 11221) refers to the inner wall of the groove opposite to the groove opening.

[0097] At least a portion of the first docking portion 141 extends into the relief groove 1122.

[0098] In some embodiments, after the first docking part 141 extends into the relief groove 1122, it shields the relief groove 1122, thereby reducing the amount of gas leakage between the first docking part 141 and the relief groove 1122.

[0099] In this embodiment, the upper end face of the first docking part 141 and the upper end face 1121 of the relief step are flush with each other, which can eliminate the height difference generated at the docking point of the evaporation cover 14 and the relief step 112, improve the aesthetics of the docking point of the evaporation cover 14 and the relief step 112, and facilitate the cleaning of the storage cavity 1112.

[0100] The freezer includes a first sealing element 2.

[0101] In some embodiments, the first seal 2 is used to seal between the evaporator cover 14 and the clearance step 112.

[0102] For example, the first seal 2 is configured as foam and fixed by adhesive, thereby reducing manufacturing costs.

[0103] The first sealing member 2 is connected to one of the first mating part 141 and the upper end face 1121 of the clearance step, and abuts against the other of the first mating part 141 and the upper end face 1121 of the clearance step.

[0104] In some embodiments, such as Figure 3 The first sealing element 2 is connected to the first mating part 141, which facilitates installation along with the evaporator cover plate 14. The first sealing element 2 abuts against the upper end face 1121 of the relief step along the first direction, and can seal the space between the first mating part 141 and the upper end face 1121 of the relief step.

[0105] The first sealing member 2 is connected to one of the first mating part 141 and the bottom surface 11221 of the relief groove, and abuts against the other of the first mating part 141 and the bottom surface 11221 of the relief groove.

[0106] In some embodiments, such as Figure 5 The first sealing member 2 abuts against the bottom surface 11221 of the relief groove along the first direction, and can seal the first mating part 141 and the bottom surface 11221 of the relief groove.

[0107] The inner liner 11 includes a bottom wall 113 that is opposite to the evaporator cover 14 along a first direction.

[0108] In some embodiments, the bottom wall 113 is located below the clearance step 112. The bottom wall 112 and the clearance step 112 are opposite each other along a third direction. The first direction is set at an angle to the third direction.

[0109] For example, a third party could be Figure 1The left and right directions within. Refer to the reference. Figure 2 and Figure 8 As shown, the bottom wall 112 is the bottom plate of the second enclosure 117, and the bottom wall 112 is located to the left of the yielding step 112.

[0110] The cabinet 1 includes a second docking structure 16.

[0111] In some embodiments, the second mating structure 16 enables the evaporator cover 14 to be inserted into the bottom wall 112.

[0112] The second docking structure 16 includes a second docking block 161 disposed on one of the evaporation cover plate 14 and the bottom wall 113, and a second docking groove 162 disposed on the other of the evaporation cover plate 14 and the bottom wall 113.

[0113] In some embodiments, the second docking block 161 is disposed on the evaporation cover plate 14 and the second docking groove 162 is disposed on the bottom wall 113, which can reduce the manufacturing difficulty of the inner liner 11 and facilitate the manufacturing of the second docking structure 16.

[0114] For example, such as Figure 6 The second docking block 161 is configured as a rib structure protruding from the end face of the evaporator cover plate 14 along a third direction, and the second docking groove 162 is configured as a groove structure recessed into the bottom wall 113 along a first direction.

[0115] The second docking block 161 and the second docking groove 162 are inserted and engaged along the first direction.

[0116] In some embodiments, the second docking structure 16 can position the docking between the evaporation cover plate 14 and the bottom wall 113, so that the evaporation cover plate 14 can overlap the bottom wall 113 and be fixed.

[0117] In this embodiment, after the second docking block 161 and the second docking groove 162 are inserted and engaged, the offset between the evaporation cover plate 14 and the bottom wall 113 can be restricted. For example, the offset between the evaporation cover plate 14 and the clearance step 112 along the third direction can be restricted.

[0118] In this embodiment, after the second docking block 161 and the second docking groove 162 are inserted and engaged, the sealing between the evaporator cover plate 14 and the bottom wall 113 can also be improved.

[0119] In this embodiment, the first docking structure 15 and the second docking structure 16 are connected in the same direction, and are both connected along the first direction, thereby realizing the synchronous connection of the two docking structures (15, 16), which simplifies the installation steps between the evaporator cover plate 14 and the inner liner 11.

[0120] The second docking block 161 is connected to the evaporation cover plate 14.

[0121] Continue to cooperate with reference Figure 8 As shown, in some embodiments, the evaporator cover 14 includes a second docking portion 142 connected to the second docking block 161, the second docking portion 142 being located below the first docking portion 141. The second docking block 161 is connected to the lower end of the second docking portion 142.

[0122] For example, the second docking portion 142 may be the lower edge of the side plate 149 of the evaporation cover plate 14, and the second docking block 161 protrudes from the left end face of the second docking portion 142.

[0123] The second docking groove 162 is recessed into the upper end face 1131 of the bottom wall.

[0124] In some embodiments, when the inner liner 11 is manufactured by one-piece molding (e.g., vacuum forming), the top end face of the entire bottom wall 113 is flush, and the upper end face 1131 of the bottom wall is the top end face of the bottom wall 113.

[0125] In other embodiments, such as Figure 6 When the inner liner 11 is configured in two parts, for example, it is formed by inserting an evaporator base plate 115 into a surrounding plate (116, 117). In this case, the upper end face 1131 of the bottom wall can be the top end face of the insertion groove 118 provided on the bottom wall 113.

[0126] At least a portion of the second docking block 161 extends into the second docking groove 162.

[0127] In some embodiments, after the second docking block 161 extends into the second docking groove 162, it can contact or be spaced apart from the bottom wall of the second docking groove 162, which can reduce the amount of gas leakage between the evaporation cover plate 14 and the bottom wall 113 at the second docking structure 16 and improve the sealing performance of the evaporation chamber 1111.

[0128] The upper surface 1131 of the bottom wall is not higher than the upper surface 1611 of the second docking block.

[0129] In some embodiments, compared to the solution where "the upper end face 1131 of the bottom wall is higher than the upper end face 1611 of the second mating block", this solution can avoid forming a groove structure at the second mating groove 162, thereby avoiding the accumulation of dirt at the groove structure.

[0130] For example, the upper end face 1131 of the bottom wall and the upper end face 1611 of the second mating block are flush with each other, which can eliminate the height difference generated at the joint between the evaporator cover 14 and the bottom wall 113, improve the aesthetics of the joint between the evaporator cover 14 and the bottom wall 113, and facilitate the cleaning of the storage cavity 1112.

[0131] The freezer includes a second sealing element 3.

[0132] In some embodiments, the second seal 3 is used to seal the space between the evaporator cover 14 and the bottom wall 113.

[0133] For example, the second seal 3 is configured as foam and fixed by adhesive, thereby reducing manufacturing costs.

[0134] The second sealing member 3 is connected to one of the second docking block 161 and the bottom surface 1621 of the second docking groove, and abuts against the other of the second docking block 161 and the bottom surface 1621 of the second docking groove.

[0135] In some embodiments, such as Figure 6 The second sealing element 3 is connected to the second mating block 161, facilitating installation along with the evaporator cover plate 14. The second sealing element 3 abuts against the bottom surface 1621 of the second mating groove along the first direction, thereby sealing the space between the second mating block 161 and the bottom surface 1621 of the second mating groove.

[0136] The inner liner 11 includes a sidewall 114 that is opposite to the evaporator cover 14 along a second direction.

[0137] In some embodiments, the sidewall 114 is located on one side of the clearance step 112 along the horizontal direction.

[0138] For example, the second direction could be Figure 1 The front and back directions within. (Refer to reference.) Figure 2 and Figure 8 As shown, the side wall 114 is the rear side plate of the evaporation base plate 115, and the side wall 114 is located behind the clearance step 112.

[0139] The cabinet 1 includes a third docking structure 17.

[0140] In some embodiments, the third mating structure 17 enables the evaporator cover 14 to be inserted into the side wall 114.

[0141] The third docking structure 17 includes a third docking block 171 disposed on one of the evaporation cover plate 14 and the side wall 114, and a third docking groove 172 disposed on the other of the evaporation cover plate 14 and the side wall 114.

[0142] In some embodiments, the third docking block 171 is disposed on the evaporation cover plate 14 and the third docking groove 172 is disposed on the side wall 114, which can reduce the manufacturing difficulty of the inner liner 11 and facilitate the manufacturing of the third docking structure 17.

[0143] For example, such as Figure 7The third docking block 171 is configured as a rib structure protruding from the end face of the evaporator cover plate 14 along a third direction or a first direction, and the third docking groove 172 is configured as a groove structure protruding from the side wall 114 along a second direction.

[0144] The third docking block 171 and the third docking groove 172 are inserted and engaged along the second direction.

[0145] In some embodiments, the third docking structure 17 can position the docking between the evaporator cover 14 and the side wall 114, so that the evaporator cover 14 can overlap the side wall 114 and be fixed.

[0146] In this embodiment, after the third docking block 171 and the third docking groove 172 are inserted and engaged, the offset between the evaporation cover plate 14 and the side wall 114 can be restricted. For example, the evaporation cover plate 14 is restricted from offsetting with the clearance step 112 along the first direction and the third direction.

[0147] In this embodiment, after the third docking block 171 and the third docking groove 172 are inserted and engaged, the sealing between the evaporator cover plate 14 and the side wall 114 can also be improved.

[0148] The second direction is set at a certain angle to the first direction.

[0149] In this embodiment, the insertion and mating direction of the third docking structure 17 is at a certain angle to the first docking structure 15 (or the second docking structure 16), which can form different directions of limiting between the evaporator cover plate 14 and the inner liner 11, thereby improving the limiting strength and sealing performance between the evaporator cover plate 14 and the inner liner 11.

[0150] In this embodiment, the second direction is perpendicular to the first direction, and the second direction can be... Figure 1 The front and back directions in the middle.

[0151] For example, when the first docking structure 15 and the second docking structure 16 are inserted and engaged along the first direction, the evaporator cover 14 can slide and engage with the inner liner 11 along the second direction, thereby realizing the insertion of the third docking block 171 and the third docking groove 172, that is, completing the insertion of the third docking structure 17.

[0152] The third docking block 171 is connected to the evaporation cover plate 14.

[0153] Continue to cooperate with reference Figure 8 As shown, in some embodiments, the evaporator cover 14 includes a third docking portion 143 connected to a third docking block 171, the third docking portion 143 being located behind the first docking portion 141 (or the second docking portion 142). The third docking block 171 is connected to the end face of the third docking portion 143 facing away from the evaporation chamber 1111.

[0154] For example, the third docking block 171 may be the rear edge portion of the top plate 148 and the side plate 149 of the evaporation cover plate 14, and the third docking block 171 protrudes from the left end face and the upper end face of the third docking portion 143.

[0155] The third docking groove 172 protrudes into the storage cavity 1112.

[0156] In some embodiments, such as Figure 4 The third docking groove 172 is formed by two protruding ribs 1722, which protrude from the side wall 114 along the second direction. At least part of the protruding ribs 1722 are connected to the evaporator fan 5, so that the evaporator cover plate 14 and the evaporator fan 5 can be mutually restrained by the third docking structure 17.

[0157] In this embodiment, compared to the solution where "the third docking groove 172 is recessed into the side wall 114", this solution makes it easier for part of the third docking groove 172 to be formed in the evaporator fan 5, thereby ensuring that the evaporator fan 5 works normally.

[0158] At least a portion of the third docking block 171 extends into the third docking groove 172.

[0159] In some embodiments, after the third docking block 171 extends into the third docking groove 172, it can contact or be spaced apart from the bottom wall of the third docking groove 172, which can reduce the amount of gas leakage between the evaporation cover plate 14 and the side wall 114 at the third docking structure 17 and improve the sealing performance of the evaporation chamber 1111.

[0160] The freezer includes a third sealing element 4.

[0161] In some embodiments, the third seal 4 is used to seal between the evaporator cover 14 and the sidewall 114.

[0162] For example, the third seal 4 is configured as foam and fixed by adhesive, thereby reducing manufacturing costs.

[0163] The third sealing element 4 is connected to one of the third docking block 171 and the bottom surface 1721 of the third docking groove, and abuts against the other of the third docking block 171 and the bottom surface 1721 of the third docking groove.

[0164] In some embodiments, such as Figure 7 The third sealing element 4 is connected to the third mating block 171, facilitating installation along with the evaporator cover plate 14. The third sealing element 4 abuts against the bottom surface 1721 of the third mating groove along the second direction, thereby sealing the space between the third mating block 171 and the bottom surface 1721 of the third mating groove.

[0165] Reference Figure 8As shown, the inner liner 11 includes an evaporation base plate 115 connected to the evaporation cover plate 14 and at least one surrounding plate (116, 117) connected to the evaporation base plate 115.

[0166] In some embodiments, the inner liner 11 is composed of an evaporation base plate 115 and surrounding plates (116, 117), which facilitates the manufacture of the complex structure of the evaporation base plate 115. Compared with a one-piece inner liner, this reduces the manufacturing difficulty of the inner liner 11, thereby reducing manufacturing costs.

[0167] The evaporation chamber 1111 is formed by the evaporation base plate 115 and the evaporation cover plate 14.

[0168] In some embodiments, the evaporation base plate 115 is connected to the surrounding plates (116, 117) to form an inner liner 11, which together form an accommodating space 111. After the evaporation cover plate 14 is connected to the evaporation base plate 115, an evaporation chamber 1111 is formed between the evaporation cover plate 14 and the evaporation base plate 115.

[0169] The aforementioned docking grooves (152, 162, 172) are integrally formed with the evaporation base plate 115.

[0170] In some embodiments, when the evaporation base plate 115 is manufactured using a vacuum forming process, the first docking groove 152, the second docking groove 162, and the third docking groove 172 are directly formed on the evaporation base plate 115, thereby facilitating the manufacture of the docking grooves (152, 162, 172) and reducing manufacturing costs.

[0171] The inner liner 11 includes a first enclosure 116 and a second enclosure 117.

[0172] In some embodiments, the first enclosure 116 and the second enclosure 117 may be manufactured in a one-piece molding manner.

[0173] For example, such as Figure 8 The first panel 116 and / or the second panel 117 are made of plastic. The first panel 116 and / or the second panel 117 are manufactured using a vacuum forming process, thereby reducing manufacturing costs.

[0174] For example, such as Figure 9 The first enclosure 116 and / or the second enclosure 117 are made of metal. The first enclosure 116 and / or the second enclosure 117 are made by bending and forming process, which improves the working strength of the inner liner 11, for example, it is not easy to deform when exposed to the sun for a long time.

[0175] The first enclosure plate 116 and the second enclosure plate 117 are respectively inserted into the opposite sides of the evaporation base plate 115 along the horizontal direction.

[0176] In some embodiments, the first enclosure plate 116 and the second enclosure plate 117 are connected to the evaporation base plate 115 by plugging in, which facilitates the docking between the enclosure plate and the evaporation base plate 115 and reduces the assembly difficulty.

[0177] In some embodiments, the first enclosure 116 and the second enclosure 117 are located on opposite sides of the evaporation base plate 115. Considering that the evaporation base plate 115 is manufactured by vacuum forming, it is only necessary to provide an insertion structure (e.g., insertion groove 118) on opposite sides of the evaporation base plate 115 to achieve insertion with the two enclosures, which reduces the manufacturing difficulty of the inner liner 11.

[0178] For example, insertion slots 118 are provided on both sides of the evaporation base plate 115, and the ends of the first enclosure plate 116 and the second enclosure plate 117 are directly inserted into the insertion slots 118.

[0179] For example, the first enclosure 116 is inserted into the right end of the evaporation base plate 115, and the second enclosure 117 is inserted into the left end of the evaporation base plate 115.

[0180] The yielding step 112 is formed by the evaporation base plate 115 and the first surrounding plate 116.

[0181] In some embodiments, the bottom plate of the first enclosure plate 116 and the right side plate of the evaporation bottom plate 115 are interlocked to form a clearance step.

[0182] Reference Figure 10 As shown, the evaporation cover plate 14 includes a first plate 144 and a second plate 145.

[0183] In some embodiments, the evaporator cover 14 is provided in separate parts, which makes it easier to install and disassemble compared to a one-piece evaporator cover 14.

[0184] Furthermore, when the evaporation chamber 1111 needs maintenance, it can be done by disassembling the first plate 144 or the second plate 145, which is beneficial for future maintenance and replacement.

[0185] In addition, the inner liner 11 may deform during the foaming process, which may cause assembly errors between the inner liner 11 and the evaporator cover plate 14. By setting the evaporator cover plate 14 separately, the aforementioned assembly errors can be adjusted by adjusting the installation gap between the first plate 144 and the second plate 145, which is beneficial to the docking between the evaporator cover plate 14 and the inner liner 11.

[0186] The first plate 144 and the second plate 145 are both connected to the evaporation base plate 115.

[0187] In some embodiments, after the first plate 144 and the second plate 145 are respectively connected to the evaporation base plate 115, the first plate 144 and the second plate 145 abut against each other.

[0188] For example, after the second plate 145 is connected to the evaporation base plate 115, the first plate 144 is connected to the docking part 1511, and then the first plate 144 is connected to the evaporation base plate 115 using a fastener.

[0189] The evaporation cover plate 14 includes a heat insulation structure 146 disposed at the end of the second plate 145.

[0190] In some embodiments, after the first plate 144 and the second plate 145 abut against each other, the thermal insulation structure 146 is used to seal the space between the first plate 144 and the second plate 145.

[0191] In addition, since the second plate 145 is fixed to the evaporation base plate 115 before the first plate 144, the insulation structure 146 is set on the second plate 145, which is conducive to the first plate 144 covering the insulation structure 146, thereby realizing the connection between the first plate 144 and the insulation structure 146.

[0192] For example, the insulation structure 146 is provided on all sides of the end of the second plate 145, namely the upper side and the left side of the front end of the second plate 145.

[0193] For example, the insulation structure 146 is located at the joint between the first plate 144 and the second plate 145. The insulation structure 146 is located on the side of the evaporator cover plate 14 facing the evaporation chamber 1111, that is, the insulation structure 146 is exposed inside the evaporation chamber 1111.

[0194] In other embodiments, the evaporation cover 14 may include more than two plates, requiring only the provision of an insulation structure 146 between adjacent plates.

[0195] Reference Figure 11 As shown, the insulation structure 146 has an insulation cavity 1461 and an insulation opening 1462 that exposes the insulation cavity 1461.

[0196] In some embodiments, the cross-section of the insulation structure 146 is open.

[0197] In some embodiments, the insulation cavity 1461 can be filled with insulation material through the insulation opening 1462. Filling the insulation cavity 1461 with insulation material improves the insulation and sealing effect of the insulation structure 146, specifically, it improves the sealing performance between the first plate 144 and the second plate 145.

[0198] For example, such as Figure 11 a. After the insulation cavity 1461 is filled with insulation material, the insulation material abuts against all the inner walls of the insulation cavity 1461.

[0199] For example, a foam board is also provided on the side of the evaporator cover 14 facing the evaporator cavity 1111, which can improve the heat preservation effect of the evaporator cavity 1111 and reduce the cold leakage between the evaporator cavity 1111 and the storage cavity 1112.

[0200] The first plate 144 covers the insulation opening 1462.

[0201] In some embodiments, after the end of the first plate 144 is covered by the insulation opening 1462, the insulation cavity 1461 is sealed to seal the joint between the first plate 144 and the second plate 145.

[0202] In addition, the first plate 144 abuts against the insulation structure 146 at its end, thereby positioning the connection between the first plate 144 and the second plate 145.

[0203] The evaporation cover plate 14 also includes a heat insulation partition plate 147 disposed on the first plate 144.

[0204] In some embodiments, the insulation partition 147 makes it difficult for the evaporation chamber 1111 to communicate with the storage chamber 1112 through the insulation chamber 1461.

[0205] The thermal insulation partition 147 protrudes into the thermal insulation cavity 1461.

[0206] In some embodiments, the free end of the thermal insulation partition 147 abuts against or is spaced apart from the inner wall of the thermal insulation cavity 1461.

[0207] The insulation cavity 1461 has a first insulation space 14611 and a second insulation space 14612 located on both sides of the insulation partition 147.

[0208] In some embodiments, when the evaporation chamber 1111 is connected to the storage chamber 1112 through the insulation chamber 1461, it needs to pass through the first insulation space 14611 and the second insulation space 14612 in sequence. Therefore, it is difficult for the evaporation chamber 1111 to be connected to the storage chamber 1112 through the insulation chamber 1461.

[0209] Furthermore, when the airflow passes through the first insulation space 14611 and the second insulation space 14612, the airflow changes direction, thereby reducing the flow of air and reducing the leakage of cold energy between the evaporation chamber 1111 and the storage chamber 1112.

[0210] The first insulation space 14611 and the second insulation space 14612 are either connected to each other or separated from each other.

[0211] In some embodiments, such as Figure 11b. When the first insulation space 14611 and the second insulation space 14612 are separated from each other, the insulation partition 147 abuts against the inner wall of the insulation cavity 1461. It is more difficult for airflow to be exchanged between the first insulation space 14611 and the second insulation space 14612, which makes the sealing between the first plate 144 and the second plate 145 better.

[0212] In some embodiments, such as Figure 11 c. When the first insulation space 14611 and the second insulation space 14612 are connected to each other, the insulation partition 147 and the inner wall of the insulation cavity 1461 are spaced apart from each other.

[0213] Compared to the solution where "the insulation partition 147 abuts against the inner wall of the insulation cavity 1461", the insulation partition 147 and the inner wall of the insulation cavity 1461 are spaced apart, which reduces the fitting accuracy between the insulation partition 147 and the insulation structure 149. This is beneficial for the manufacturing of the evaporation cover plate 14 and facilitates the connection between the insulation partition 147 and the insulation structure 149.

[0214] The first insulation space 14611 and / or the second insulation space 14612 are filled with insulation material.

[0215] In some embodiments, such as Figure 11 a. The first insulation space 14611 and the second insulation space 14612 are separated from each other. After the first insulation space 14611 (or the second insulation space 14612) is filled with insulation material, the insulation material cannot enter the second insulation space 14612 (or the first insulation space 14611), thereby reducing the use of insulation material and reducing manufacturing costs.

[0216] In some embodiments, such as Figure 11 c. The first insulation space 14611 and the second insulation space 14612 are interconnected. After the first insulation space 14611 (or the second insulation space 14612) is filled with insulation material, the insulation material can partially enter the second insulation space 14612 (or the first insulation space 14611).

[0217] Thus, the gap between the insulation partition 147 and the inner wall of the insulation cavity 1461 is sealed, improving the sealing effect of the insulation structure 149.

[0218] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0219] The detailed descriptions listed above are merely specific descriptions of feasible implementation methods of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementation methods or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
