[0037] The embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only, and are used only for explaining the present application, and cannot be understood as a limitation of the present application.

[0038] The following refers to Figures 1-7 The refrigeration equipment according to the embodiments of the present application is described.

[0039] Please refer to Figure 1 The embodiments of the present application provide a refrigeration equipment 1000, which comprises a cabinet 100 and an air duct module 200.

[0040] The refrigeration equipment 1000 provided by the embodiments of the present application can be a side cabinet, a refrigerator, a freezer or a wine cabinet, etc., and is not specifically limited.

[0041] Please refer to Figure 1 and Figure 2The box 100 includes an outer shell, an insulation layer, and an inner container 110. The outer shell can be made of metal (such as steel plate), and the surface is treated with paint to prevent rust and has a certain aesthetic appearance. The insulation layer is located between the inner side of the outer shell and the inner container 110, and can be polyurethane foam, which has good heat insulation performance and can effectively prevent heat exchange between the inside and outside, thereby maintaining the internal temperature stable. The inner container 110 is the part that directly contacts the stored objects, and is generally made of ABS plastic or stainless steel material, which is non-toxic and easy to clean. The inner container 110 forms a refrigeration cavity inside for accommodating the stored objects. The rear wall 112 of the refrigeration cavity is provided with a plurality of protrusions 111, i.e., the rear wall 112 of the inner container 110 is provided with a plurality of protrusions 111.

[0042] A drawer can be provided in the refrigeration cavity. The drawer is slidably installed in the refrigeration cavity, and helps users to store different types of stored objects separately, thereby improving the convenience of use. Independent temperature control can be provided for different drawers to meet the optimal storage temperature of different foods. The drawer is usually detachable, and users can easily take it out for cleaning, thereby maintaining the hygiene of the inside of the refrigerator. The drawer also facilitates the setting of various functional partitions, such as an egg shelf, a seasoning box, etc., thereby facilitating users to store various small items.

[0043] The refrigeration cavity can include a refrigeration chamber and a freezing chamber, or only one of the refrigeration chamber and the freezing chamber. The temperatures of different chambers are different, and the functions are different. The different temperature ranges of the refrigeration chamber and the freezing chamber can be adjusted by a temperature control device provided in or outside the box 100.

[0044] The refrigeration device 1000 also includes a door body. The door body is provided on the front side of the box 100, specifically at the opening of the refrigeration cavity. The door body also includes an outer shell, an insulation material, and an inner lining, thereby ensuring good sealing performance and heat preservation effect. The door body can be connected to the box 100 by a hinge structure, allowing the door to open and close freely. The door body can be a single door or a double door, and the single door can also have a function of adjusting the opening direction left and right. A sealing strip can be installed at the edge of the door body, which tightly contacts the box 100 and prevents cold air leakage, thereby sealing the refrigeration cavity together with the box 100.

[0045] Please refer to Figure 3 The air duct module 200 is installed in the refrigeration cavity. The air duct module 200 includes a shell 210, a fan 240, and an evaporator 220. The shell 210 is connected to the rear wall 112, and the shell 210 has a cavity for gas circulation and a air supply port 2144 communicating with the cavity. The fan 240 and the evaporator 220 are installed in the cavity.

[0046] The shell 210 is internally provided with a cavity for gas circulation, which can be part of an air duct. The cavity is also used to accommodate devices and pipelines such as the evaporator 220, the fan 240, and the air return pipe. The shell 210 can be made of metal material to have good mechanical strength and corrosion resistance, or can be made of composite material to have good corrosion resistance, light weight, and good thermal insulation. This not only reduces the weight of the entire air duct module 200, but also improves the heat preservation effect and reduces energy consumption.

[0047] The shell 210 is also provided with an air supply port 2144 in communication with the cavity. The air supply port 2144 is used to send cold air in the cavity into the refrigeration cavity. The fan 240 is used to drive the circulation of cold air in the refrigeration cavity and the cavity, improving the refrigeration efficiency. The evaporator 220 is used to absorb heat to achieve the refrigeration effect. The fan 240 and the evaporator 220 can be fixed in the shell 210 by a support to ensure their stability and reliability.

[0048] Please refer to Figure 3 According to some embodiments of the present application, the shell 210 can include a first side plate 211 and a second side plate 212 spaced apart from each other. The first side plate 211 and the second side plate 212 are arranged in the thickness direction of the shell 210. The shell 210 can also include a front plate 213 and a rear plate 214 spaced apart from each other. For example, the refrigeration equipment 1000 is a vertical side table. One side of the shell 210 provided with a door body is the front side, and the bottom in the depth direction of the refrigeration cavity is the rear side. The rear plate 214 is used to connect with the rear wall 112. The front plate 213 is located on the side close to the door body. The first side plate 211 and the second side plate 212 are distributed in the left-right direction. The left and right ends of the front plate 213 are connected with the front ends of the first side plate 211 and the second side plate 212, respectively. The left and right ends of the rear plate 214 are connected with the rear ends of the first side plate 211 and the second side plate 212, respectively, to form a cavity for accommodating devices such as the evaporator 220 and the fan 240.

[0049] The first side plate 211, the second side plate 212, the front plate 213, and the rear plate 214 form an independent cavity, so that the air duct module 200 forms a relatively independent module. When the module is assembled in the refrigeration cavity as a whole, the number of parts is small, the assembly steps are few, and the assembly difficulty is low. However, there is still room for improvement in the positioning efficiency during assembly.

[0050] Please refer to Figure 4 The plurality of protrusions 111 are arranged on the side of the shell 210 and limit the end of the shell 210 connected with the rear wall 112.

[0051] The rear plate 214 of the shell 210 is connected with the rear wall 112 to fix the shell 210. A plurality of protrusions 111 are arranged on the rear wall 112, and the protrusions 111 are located at the side of the connection position of the shell 210, so that the side of the rear plate 214 is matched with the protrusions 111 during assembly, thereby facilitating the operator to accurately position and connect the shell 210 with the rear wall 112, and greatly improving the assembly efficiency. In addition, the plurality of protrusions 111 also limit the end of the shell 210 connected with the rear wall 112, thereby assisting in fixing the shell 210, which can not only improve the stability during assembly, but also improve the stability of the entire air duct module 200 during daily use, reduce noise, and improve durability.

[0052] According to the refrigeration equipment 1000 provided by the embodiment of the present application, the air duct module 200 includes a shell 210, and the fan 240 and the evaporator 220 are integrated in the shell 210 to assemble the air duct module 200 as an independent module, which has low assembly difficulty. The plurality of protrusions 111 arranged on the inner container 110 limit the shell 210, thereby positioning and assisting in fixing the shell 210 during installation, improving the stability of the air duct module 200 during assembly, and reducing the assembly difficulty and improving the assembly efficiency.

[0053] Please refer to Figure 4 According to some embodiments of the present application, the shell 210 can be arranged in the middle part of the refrigeration cavity to divide the refrigeration cavity into the first chamber 120 and the second chamber 130, and the plurality of protrusions 111 can be distributed in the first chamber 120 and the second chamber 130.

[0054] The shell 210 can be arranged in the middle part of the refrigeration cavity as a partition plate. For example, the shell 210 is arranged in the middle part of the refrigeration cavity in the width direction, and the shell 210 divides the refrigeration cavity along the width direction to form the first chamber 120 and the second chamber 130 which are spaced apart from each other. The two sides of the shell 210 are respectively provided with air supply ports 2144 corresponding to the first chamber 120 and the second chamber 130, so as to supply air to the first chamber 120 and the second chamber 130 respectively, and simultaneously perform the refrigeration function on the first chamber 120 and the second chamber 130. The air volume of the air supply ports 2144 on the two sides can be controlled to control the temperature of the first chamber 120 and the second chamber 130, wherein the temperature of the first chamber 120 and the second chamber 130 can be the same or different, which is not limited.

[0055] The plurality of protrusions 111 can be distributed in the first cavity 120 and the second cavity 130. When the air duct module 200 is assembled, the plurality of protrusions 111 distributed in the width direction of the refrigeration cavity define the mounting position of the shell 210, and the positioning and guiding effect is more stable. After the shell 210 is assembled, the plurality of protrusions 111 are distributed on both sides of the shell 210 and adjacent to the shell 210, so as to simultaneously position both sides of the shell 210, and the mounting stability of the shell 210 is higher.

[0056] Referring to Figure 4 and Figure 5 According to some embodiments of the present application, the shell 210 can include an air supply pipe 2143 arranged at one end of the shell 210 connected with the rear wall 112 and extending in the lateral direction. An air supply opening 2144 is arranged on the air supply pipe 2143, and the end of the air supply pipe 2143 abuts against the protrusion 111.

[0057] The air supply pipe 2143 is arranged at one end of the shell 210 connected with the rear wall 112 and extends in the lateral direction, so that the air supply pipe 2143 extends at least partially outside the main body of the shell 210 and is located at the rear side of the refrigeration cavity. Specifically, the rear plate 214 includes the air supply pipe 2143, which can extend laterally to the outside of the first side plate 211 or the second side plate 212 to correspond to the refrigeration cavity. The air supply opening 2144 is arranged on the air supply pipe 2143, so that the air supply opening 2144 is at least partially located at the rear side of the refrigeration cavity, facilitating air supply into the refrigeration cavity. Specifically, the front side of the air supply pipe 2143 is open to form the air supply opening 2144, so that the air supply opening 2144 can be at least partially directed to the front side, allowing the air supply opening 2144 to better supply air obliquely forward, improving air supply efficiency and improving the circulation effect of cold air.

[0058] The end of the air supply pipe 2143 abuts against the protrusion 111. The end of the air supply pipe 2143 refers to the air outlet end of the air supply pipe 2143 in the air supply direction. The air supply pipe 2143 is part of the shell 210, that is, when the air duct module 200 is assembled, the air supply pipe 2143 is installed together with the shell 210. By arranging the protrusion 111 to directly abut against the end of the air supply pipe 2143, the assembly accuracy and stability are improved.

[0059] Taking the first side plate 211 on the left side and the second side plate 212 on the right side as an example, the first side plate 211 corresponds to the first cavity 120, and the second side plate 212 corresponds to the second cavity 130. Because air needs to be supplied into the first cavity 120 and the second cavity 130 respectively, the rear plate 214 can be provided with the air supply pipe 2143 and the air supply opening 2144 on both sides, and the protrusions 111 on both sides of the shell 210 abut against the corresponding air supply pipes 2143.

[0060] Referring to Figure 6According to some embodiments of the present application, the end of the air supply pipe 2143 is shaped to match the protrusion 111.

[0061] By setting the end of the air supply pipe 2143 to match the shape of the protrusion 111, the accuracy and stability of the assembly of the shell 210 are improved. After assembly is completed, the end of the air supply pipe 2143 can be in contact with the surface of the protrusion 111, ensuring close contact between the air supply pipe 2143 and the protrusion 111, and the overall installation stability is higher, and the air supply pipe 2143 is not easy to deviate during use or pulling.

[0062] Please refer to Figure 4 According to some embodiments of the present application, the air supply pipe 2143 can be provided with a plurality of air supply pipes 2143 distributed along the height direction, and the plurality of air supply pipes 2143 correspond to at least part of the protrusions 111 one by one.

[0063] The rear plate 214 can be provided with an air supply channel 2141 extending along the height direction. By setting the air supply channel 2141 extending along the height direction in the rear plate 214, it is ensured that the cold air can be uniformly distributed at different height positions, improving the cooling effect. The air supply channel 2141 is in communication with the cavity, and the fan 240 works to transport the air in the cavity to the air supply channel 2141. It should be noted that the two ends of the shell 210 in the height direction are connected to the top wall and the bottom wall of the refrigeration cavity, so that the air supply channel 2141 can cover as many positions in the height direction of the refrigeration cavity as possible.

[0064] The air supply pipe 2143 can be provided with a plurality of air supply pipes 2143 distributed along the height direction, that is, the air supply port 2144 is provided with a plurality of air supply ports 2144 distributed along the height direction. The plurality of air supply ports 2144 can be arranged at intervals along the height direction, so that the cold air can be uniformly distributed at different height positions, improving the efficiency of air flow and the uniformity of temperature in the refrigeration cavity, and ensuring the refrigeration effect at each position.

[0065] By setting a plurality of air supply pipes 2143 corresponding to at least part of the protrusions 111 one by one, the end of each air supply pipe 2143 is provided with a protrusion 111 abutting and limiting, which improves the refrigeration effect and improves the overall installation stability of the shell 210.

[0066] The number of air supply pipes 2143 in the height direction is not limited, which can be two, three, four or more, and can be determined according to air flow organization or the number of compartments in the refrigeration cavity. For example, when there are three drawers in the refrigeration cavity, the air supply pipe 2143 can be provided with three air supply pipes 2143 distributed along the height direction, and the three air supply pipes 2143 correspond to the three drawers respectively.

[0067] It should be noted that the opening size of the air outlet 2144 determines the flow area of the air outlet 2144 to some extent, and the greater the flow area, the smaller the resistance, and thus the air volume allocated to the corresponding air outlet 2144 can be adjusted. Because the air outlet 2144 is arranged on the side of the air supply pipe 2143 away from the rear wall 112, the length of the air supply pipe 2143 determines the size of the air outlet 2144. Moreover, the air pressure at each position of the air supply channel 2141 in the height direction is different.

[0068] In some embodiments, the length of at least one air supply pipe 2143 is different from the length of the other air supply pipes 2143, and the distance between at least one protrusion 111 and the first side plate 211 or the second side plate 212 is different from the distance between the other protrusions 111.

[0069] By setting the length of at least one air supply pipe 2143 to be different from the length of the air supply pipe 2143 at other heights, that is, the flow area of at least one air outlet 2144 is different from the flow area of the air outlet 2144 at other heights, the air volume of the plurality of air outlets 2144 can be adjusted to make the air volume of the plurality of air outlets 2144 tend to be the same, or the air volume of each air outlet 2144 can be different to accurately adjust the temperature distribution in the refrigeration cavity.

[0070] Correspondingly, the position of each protrusion 111 depends on the length of the corresponding air supply pipe 2143. Taking the case where the air supply pipe 2143 is arranged on the side close to the first side plate 211 as an example, the longer the length of the air supply pipe 2143, the greater the distance between the protrusion 111 and the first side plate 211, and vice versa.

[0071] Please refer to Figure 4 In some embodiments, the air supply pipe 2143 can be provided with three air supply pipes 2143 distributed along the height direction, and the length of the air supply pipe 2143 at the upper end is the longest.

[0072] Please refer to Figure 4 and Figure 6 According to some embodiments of the present application, at least part of the protrusions 111 are arranged between two adjacent air supply pipes 2143, and the protrusions 111 located between the two adjacent air supply pipes 2143 are spaced apart from the shell 210.

[0073] It can be understood that, in order to ensure the stability of the air supply speed and the air supply direction of the air supply pipe 2143, the width of the air supply pipe 2143, that is, the space occupied by the air supply pipe 2143 in the height direction, is relatively small with respect to the height of the entire shell 210.

[0074] By setting at least part of the protrusions 111 between two adjacent air supply pipes 2143, the part of the shell 210 without the air supply pipe 2143 in the height direction is limited, and because the part of the area occupies a large space, the protrusions 111 set between two adjacent air supply pipes 2143 can extend in the height direction to improve the positioning and guiding effect. And by setting the part of the protrusions 111 at a distance from the shell 210, the part of the protrusions 111 can play a guiding role when the shell 210 is assembled, while reducing the impact of processing errors on the assembly quality, improving the fault tolerance rate during production and assembly, reducing the requirement for processing precision, thereby reducing production cost and improving assembly efficiency.

[0075] Referring to Figure 5 and Figure 6 According to some embodiments of the present application, the side of the protrusion 111 close to the air supply pipe 2143 is provided with a first guide inclined surface 1111.

[0076] Because the protrusion 111 is in contact with the air supply pipe 2143 during assembly and after assembly, by setting the first guide inclined surface 1111 on the side of the protrusion 111 close to the air supply pipe 2143, the smoothness and accuracy during assembly are improved, friction is reduced, assembly efficiency is improved, and after assembly, a certain supporting force is provided to ensure the stability of the shell 210.

[0077] For the protrusion 111 set between two adjacent air supply pipes 2143, the side of the part of the protrusion 111 close to the shell 210 is also provided with a guide inclined surface to improve the smoothness and accuracy during assembly, reduce friction, and improve assembly efficiency.

[0078] Referring to Figure 5 and Figure 6 According to some embodiments of the present application, the first guide inclined surface 1111 is inclined forward in a direction away from the shell 210.

[0079] By limiting the inclination direction of the first guide inclined surface 1111, the first guide inclined surface 1111 can play a good guiding role during assembly.

[0080] And in an example, the end of the air supply pipe 2143 away from the air supply duct 2141 can be open, which can reduce the closed structure on the shell 210, greatly reduce the production difficulty during injection molding or casting, and reduce the production cost. Thus, when the cold air flows to the end of the air supply pipe 2143, it can contact the first guide inclined surface 1111, so that the first guide inclined surface 1111 also plays a guiding role on the air supply direction.

[0081] When the cold air reaches the air outlet of the air supply duct 2143, it is tilted and delivered under the action of the first guide slope 1111. The first guide slope 1111 is tilted away from the rear wall 112 along the air outlet direction, that is, tilted towards the middle of the refrigeration cavity where the air supply duct 2143 is located, so as to guide the cold air to the middle of the refrigeration cavity and blow it in a diagonal direction, thereby improving the circulation efficiency of the cold air in the refrigeration cavity, improving the refrigeration efficiency, and improving the temperature uniformity of the entire refrigeration cavity.

[0082] For example, the bump 111 can be a triangular protrusion with the hypotenuse of the triangular protrusion facing the air duct 2143.

[0083] Please see Figure 5 and Figure 7 According to some embodiments of this application, the side of the housing 210 may be provided with a second guide slope 2162 corresponding to the air outlet 2144.

[0084] The second guide slope 2162 can be set on the first side plate 211 and the second side plate 212. The second guide slope 2162 is set towards the air outlet 2144 to guide the cold air blown out of the air outlet 2144 and reduce the resistance of the air outlet 2144 to a certain extent.

[0085] The second guide slope 2162 can be inclined away from the rear wall 112 along the air supply direction, that is, inclined toward the middle of the cooling cavity where the air outlet 2144 is located. By limiting the inclination direction of the second guide slope 2162, the air supply direction is guided. The cold air is inclined and delivered under the action of the second guide slope 2162, so as to guide the cold air to the middle of the cooling cavity where it is located and blow it diagonally. This can make the cold air circulate better in the cooling cavity and ensure the cooling effect at each position.

[0086] The first guide slope 1111 and the second guide slope 2162 work together to guide the air supply direction of the air outlet 2144, so that the cold air can be better blown in the target direction after entering the air supply pipe 2143, reducing the air supply resistance, improving the air supply efficiency, and facilitating accurate control of the air supply direction.

[0087] Please see Figure 5 According to some embodiments of this application, the protrusion 111 may be integrally formed with the inner liner 110.

[0088] The protrusion 111 is integrally formed with the inner liner 110 to simplify the manufacturing and assembly process, improve production efficiency, and enhance the stability and reliability of the structure.

[0089] According to some embodiments of this application, the thickness H of the housing 210 in the width direction of the cooling cavity can satisfy: 55mm≤H≤85mm.

[0090] By limiting the thickness H of the shell 210, the thickness of the shell 210 is made super thin, and the internal space is arranged compactly. The air duct module 200 does not occupy the thickness of the refrigeration equipment 1000, reduces the thickness of the refrigeration equipment 1000, reduces the occupation of the internal space of the refrigeration cavity, and improves the overall space utilization.
