[0042] Embodiments of the present application are described below in detail, examples of which are shown in the 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 for the purpose of explanation of the present application, and are not to be understood as a limitation of the present application.

[0043] Reference is made to Figures 1-8 A duct module and a refrigeration appliance according to embodiments of the present application are described below.

[0044] Reference is made to Figure 1 The present embodiments provide a refrigeration appliance 1000, which comprises a cabinet 100, a door body and a duct module 200.

[0045] The cabinet 100 is provided with a refrigeration cavity, and the duct module 200 is arranged in the refrigeration cavity.

[0046] The refrigeration appliance 1000 provided by the present embodiments can be a side cabinet, a refrigerator, a freezer or a wine cabinet, etc., and is not specifically limited.

[0047] Reference is made to Figure 1 The cabinet 100 comprises an outer shell, a thermal insulation layer and an inner container 110. The outer shell can be made of metal (such as steel plate), and the surface is treated by paint spraying to prevent rust and has a certain aesthetic appearance. The thermal 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 directly contacting the stored objects, and can generally be made of ABS plastic or stainless steel material, which is required to be non-toxic and easy to clean. The inner container 110 has a refrigeration cavity formed therein for accommodating the stored objects.

[0048] The refrigeration cavity can comprise a refrigeration chamber and a freezing chamber, or only one of the refrigeration chamber and the freezing chamber, and the different chambers have different temperatures and different functions. The different temperature ranges of the refrigeration chamber and the freezing chamber can be adjusted by a temperature control device arranged in or outside the cabinet 100.

[0049] The door body also comprises an outer shell, a thermal insulation material and an inner lining, which ensures good sealing and thermal insulation effects. The door body can be connected to the cabinet 100 through 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 fits the cabinet 100 to prevent cold air leakage and cooperates with the cabinet 100 to seal the refrigeration cavity.

[0050] The duct module 200 is arranged in the refrigeration cavity.

[0051] The specific structure of the air duct module 200 can refer to the following technical solutions.

[0052] Please refer to Figure 2 and Figure 3 The air duct module 200 provided by the embodiment of the present application comprises a shell 210, a fan 240 and an evaporator 220.

[0053] The shell 210 is used to be installed in the refrigeration cavity and connected with the rear wall 112 of the refrigeration cavity. The shell 210 is provided with a cavity for gas flow. The end of the shell 210 used to be connected with the rear wall 112 is provided with a plurality of air supply ports 2144 distributed along the height direction.

[0054] The cavity in the shell 210 can be used as a part of the air duct. The cavity is also used to accommodate the evaporator 220, the fan 240 and the gas return pipe and other devices and pipelines. 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. The shell 210 can not only reduce the weight of the entire air duct module 200, but also improve the heat preservation effect and reduce the energy consumption.

[0055] The rear wall 112 of the refrigeration cavity is the rear wall 112 of the inner container 110, that is, the side wall at one end of the refrigeration cavity in the depth direction, and the rear wall 112 extends along the height direction. The end of the shell 210 used to be connected with the rear wall 112 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 and the efficiency of gas flow can be improved. In addition, the plurality of air supply ports 2144 are arranged at the rear end of the shell 210, that is, at the rear end corresponding to one side of the refrigeration cavity. By arranging the air supply ports 2144 at the corner position of the refrigeration cavity, the interference with the drawer in the refrigeration cavity can be reduced, so that the effective volume of the drawer can be increased and the storage space can be improved.

[0056] The fan 240 and the evaporator 220 are arranged in the cavity. The fan 240 is used to drive the cold air to circulate in the refrigeration cavity and the cavity, so as to improve 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 the stability and reliability thereof.

[0057] The air volume of the plurality of air supply ports 2144 is different, and the air volume of the air supply port 2144 located at the upper end is the largest.

[0058] The air volume of the plurality of air outlets 2144 is different, that is, the air volume of each air outlet 2144 is carefully designed to ensure the uniformity of the temperature at each position in the height direction and meet the needs of each space.

[0059] The air volume of the air outlet 2144 at the upper end is the largest. It can be understood that the air outlet 2144 at the upper end is arranged close to the top of the refrigeration cavity where the air duct module 200 is located. This design can ensure that the gas flow at the top region is stronger, thereby better achieving the cooling effect. Specifically, in the refrigeration equipment 1000, the temperature at the top is usually higher than that at the bottom because the cold air sinks and the hot air rises, forming a clear temperature gradient. The largest air volume of the air outlet 2144 at the upper end can more effectively capture and replace the hot air accumulated at the top, thereby accelerating the air circulation in the entire inner container 110, which helps to reduce the temperature gradient at the top region and ensure that the temperature in the entire inner container 110 is more uniform. Moreover, during the refrigeration process, the cold air at the top is prone to cause the formation of condensate water. The largest air volume of the air outlet 2144 at the upper end can accelerate the flow of cold air and reduce the accumulation of condensate water, which helps to keep the inside of the inner container 110 dry and prevent moisture from damaging the internal components and items.

[0060] In actual implementation, the air volume of the plurality of air outlets 2144 distributed in the height direction is controlled by controlling the maximum flow area of the plurality of air outlets 2144 distributed in the height direction, that is, the maximum flow area of the air outlet 2144 at the upper end is the largest, so the air volume of the air outlet 2144 at the upper end is the largest.

[0061] According to the air duct module 200 provided in the embodiments of the present application, the plurality of air outlets 2144 distributed in the height direction are arranged to facilitate air supply to each position in the height direction of the refrigeration cavity, the air volume of the plurality of air outlets 2144 is different to facilitate targeted control of the cold quantity at each position, and the air volume of the air outlet 2144 at the upper end is the largest to utilize the principle of cold air sinking and hot air rising, ensure the temperature stability at the upper end of the refrigeration cavity, reduce condensation, and ensure the stability and uniformity of the temperature in the entire refrigeration cavity through the large amount of cold air descending.

[0062] According to the refrigeration equipment 1000 provided in the embodiments of the present application, the plurality of air outlets 2144 distributed in the height direction are arranged to facilitate air supply to each position in the height direction of the refrigeration cavity, the air volume of the plurality of air outlets 2144 is different to facilitate targeted control of the cold quantity at each position, and the air volume of the air outlet 2144 at the upper end is the largest to utilize the principle of cold air sinking and hot air rising, ensure the temperature stability at the upper end of the refrigeration cavity, reduce condensation, and ensure the stability and uniformity of the temperature in the entire refrigeration cavity through the large amount of cold air descending.

[0063] In some embodiments, the housing 210 may be disposed on a side wall close to the inner liner 110, and a plurality of air outlets 2144 may be disposed on the side of the housing 210 away from the side wall, and the cooling cavity in which the air duct module 200 is located may be a single cavity.

[0064] Please see Figure 1 and Figure 4 According to some embodiments of this application, the inner liner 110 is provided with a cooling chamber, and the shell 210 can be disposed in the middle of the cooling chamber to divide the cooling chamber into a first chamber 120 and a second chamber 130. Multiple air outlets 2144 are provided on both sides of the shell 210.

[0065] The housing 210 is disposed in the middle of the cooling cavity as a partition. Taking the housing 210 disposed in the middle of the cooling cavity in the width direction as an example, the housing 210 can divide the cooling cavity along the width direction to form a first chamber 120 and a second chamber 130 that are spaced apart from each other. Multiple air outlets 2144 corresponding to the first chamber 120 and the second chamber 130 are respectively provided on both sides of the housing 210 to supply air to the first chamber 120 and the second chamber 130, so that the first chamber 120 and the second chamber 130 can be cooled simultaneously. The temperature of the first chamber 120 and the second chamber 130 can be controlled by controlling the air volume of the air outlets 2144 on both sides. The temperatures of the first chamber 120 and the second chamber 130 can be the same or different, without specific limitation.

[0066] It should be noted that the multiple air outlets 2144 on both sides of the housing 210 can be set one-to-one along the height direction to facilitate the distribution of air volume.

[0067] In one example, such as Figure 1 As shown, the housing 100 may be provided with a refrigeration chamber and a freezing chamber distributed in the vertical direction, and the air duct module 200 may be installed in the freezing chamber.

[0068] In actual implementation, taking the air duct module 200 installed inside the refrigeration chamber as an example, when the width of the refrigeration chamber is large, the air duct module 200 is centrally positioned to facilitate air supply to the first chamber 120 and the second chamber 130 respectively. Without temperature differentiation, the air volume of the first chamber 120 and the second chamber 130 can be controlled to be uniform, improving the temperature uniformity of the entire refrigeration chamber. With temperature differentiation, the air volume of the first chamber 120 and the second chamber 130 can be controlled to be different, realizing storage space with multiple different temperature ranges and improving ease of use.

[0069] According to the refrigeration equipment 1000 provided by the embodiment of the present application, the air duct module 200 is arranged at the middle part of the cabinet 100, which can improve the temperature uniformity of the first chamber 120 and the second chamber 130, and can also make the temperature of the first chamber 120 and the second chamber 130 different by distributing different air volume, which is convenient to use, simple to assemble, efficient, convenient to maintain, and can reduce the assembly and maintenance costs.

[0070] Please refer to Figures 1 to 4 According to some embodiments of the present application, the end of the shell 210 connected with the rear wall 112 can be provided with at least three air supply openings 2144 distributed along the height direction; wherein the air supply amount of the air supply opening 2144 at the upper end can be not less than the sum of the air supply amounts of the remaining air supply openings 2144.

[0071] At least three air supply openings 2144 distributed along the height direction are arranged, so as to meet the requirement of multi-point air supply, improve the uniformity of cold air at different heights, and facilitate targeted adjustment, so that the gas flow in the whole inner container 110 is more uniform. For example, in Figure 4 the air supply opening 2144 is provided with three air supply openings 2144 distributed along the height direction, in another example, the air supply opening 2144 can be provided with four, five or more air supply openings 2144 distributed along the height direction, and the specific number is not limited.

[0072] The air supply amount of the air supply opening 2144 at the upper end is not less than the sum of the air supply amounts of the remaining air supply openings 2144 below it, so as to ensure that the air supply opening 2144 at the upper end has sufficient cold air blowing out, reduce the hot air accumulated at the top, and under the principle of cold air descending, sink downward, reduce the temperature gradient in the height direction in the refrigeration cavity, and improve the circulation speed, and reduce the generation of condensed water.

[0073] According to some embodiments of the present application, the middle part of the shell 210 in the height direction is provided with a first air return opening 215, and the air supply amount of the air supply opening 2144 at the middle part is less than the air supply amount of the air supply opening 2144 at the lower end.

[0074] The air in the refrigeration cavity can enter the cavity through the first air return opening 215 and then blow out through the plurality of air supply openings 2144. The middle part of the shell 210 in the height direction is provided with the first air return opening 215, and the air return position of the shell 210 is at the middle height inside the inner container 110, which can effectively recover the air at the middle part and promote the up-down circulation of the air.

[0075] Because the middle air outlet 2144 is closer to the first return air outlet 215, by reducing the air volume of the middle air outlet 2144 and increasing the air volume of the lower air outlet 2144, the gas flow at different height positions can be optimized, the cold air at the lower end can flow to the middle part more effectively, the temperature gradient is reduced, and the cooling efficiency is improved.

[0076] Referring to Figure 4 In some embodiments, the air outlet 2144 is provided with three air outlets 2144 distributed along the height direction (three pairs in the case of air outlet 2144 provided on both sides of the shell 210), and the air volume ratio of the three air outlets 2144 from top to bottom can be 5:2:3. Further, the flow area ratio of the three air outlets 2144 from top to bottom is also 5:2:3.

[0077] Referring to Figure 3 and Figure 5 According to some embodiments of the present application, a volute 230 can be provided in the cavity, the volute 230 is provided at the upper end of the shell 210, the fan 240 is arranged in the volute 230, and the end of the shell 210 for connecting with the rear wall 112 can be provided with an air supply channel 2141 extending along the height direction, a plurality of air outlets 2144 are arranged on the side of the air supply channel 2141, and the air outlet 231 of the volute 230 is connected with the side of the air supply channel 2141 away from the rear wall 112.

[0078] The volute 230 is installed in the cavity to guide the airflow in the cavity, and by installing the fan 240 in the volute 230, the efficiency of the fan 240 can be improved, and the stability and uniformity of the airflow can be improved.

[0079] The end of the shell 210 for connecting with the rear wall 112 is provided with an air supply channel 2141, and the air supply channel 2141 extends along the height direction to ensure that the cold air can be uniformly distributed at different height positions, thereby improving the cooling effect. The air inlet of the volute 230 is located in the cavity, and the air outlet 231 of the volute 230 is connected with the air supply channel 2141, so that the cold air driven by the fan 240 enters the air supply channel 2141 through the air outlet of the volute 230 and is distributed along the height direction. It should be noted that the two ends of the shell 210 in the height direction are connected with 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. By providing the air supply channel 2141, the structural design of the volute 230 can be simplified, the production and design cost can be reduced, and the installation position of the volute 230 is also more flexible.

[0080] A plurality of air supply openings 2144 distributed in the height direction are arranged on the side of the air supply channel 2141 and communicate with the air supply channel 2141. When the cold air flows through the air supply channel 2141 and passes through the air supply opening 2144, the cold air can be blown out of the air supply opening 2144 into the refrigeration cavity. The air supply opening 2144 is arranged on the side of the air supply channel 2141 so that the air supply opening 2144 is located on one side of the shell 210 and blows into the refrigeration cavity from the corner position of the refrigeration cavity, thereby reducing the influence of the air supply opening 2144 on the drawer in the refrigeration cavity.

[0081] Referring to Figure 3 and Figure 5 According to some embodiments of the present application, the air outlet 231 of the volute 230 can be connected between the air supply opening 2144 at the upper end and the air supply opening 2144 at the middle.

[0082] By connecting the air outlet 231 of the volute 230 between the air supply opening 2144 at the upper end and the air supply opening 2144 at the middle, it is ensured that the air flow from the volute 230 first enters the air supply opening 2144 at the upper end, ensuring the air supply amount of the air supply opening 2144 at the upper end, and then being uniformly distributed to the refrigeration cavity through the other air supply openings 2144 below the air supply opening 2144 at the upper end. Moreover, the volute 230 is arranged at the upper end of the shell 210, and by connecting the air outlet 231 to the upper position of the air supply channel 2141, the structure of the volute 230 can be simplified and the space layout can be optimized.

[0083] Specifically, the air outlet 231 of the volute can be connected between the air supply opening 2144 at the upper end and the air supply opening 2144 adjacent to it in the height direction.

[0084] Referring to Figure 6 According to some embodiments of the present application, the shell 210 includes first and second side plates 211 and 212 spaced apart from each other, and the volute 230 is mounted in one of the first and second side plates 211 and 212.

[0085] The shell 210 can include a first side plate 211 and a second side plate 212 spaced apart from each other and arranged along the thickness direction of the shell 210. The shell 210 can further include a front plate 213 and a rear plate 214. For example, for a refrigerator 1000 in the form of a standing bar, the side provided with the door body is the front side, and the bottom in the depth direction of the refrigerating cavity is the rear side. The rear plate 214 is used to be connected with the rear wall 112. The air supply channel 2141 can be arranged in the rear plate 214, and the air supply port 2144 is arranged on the side of the rear plate 214. The front plate 213 is arranged on the side close to the door body. The first side plate 211 and the second side plate 212 are distributed along 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, so as to enclose a cavity for accommodating devices such as the evaporator 220 and the fan 240.

[0086] The volute 230 is mounted on one of the first side plate 211 and the second side plate 212 to ensure the stability of the mounting of the volute 230, and the first side plate 211 and the second side plate 212 have a large coverage area, facilitating flexible arrangement of the volute 230.

[0087] Please refer to Figure 7 and Figure 8 According to some embodiments of the present application, the side wall of the air outlet 231 of the volute 230 is inclined towards the other one of the first side plate 211 and the second side plate 212 in the air outlet direction.

[0088] First of all, it should be pointed out that the volute 230 is arranged apart from the other one of the first side plate 211 and the second side plate 212, and the air inlet of the volute 230 is arranged on the side facing the other one of the first side plate 211 and the second side plate 212. For example, when the volute 230 is mounted on the first side plate 211, the air inlet of the volute 230 is arranged on the side close to the second side plate 212.

[0089] It can be understood that the side wall of the air supply channel 2141 is aligned with the first side plate 211 and the second side plate 212. When the volute 230 is mounted on the first side plate 211 or the second side plate 212, the fan 240 in the volute 230 will be directly opposite to one side of the air supply channel 2141, affecting the uniformity of air supply. By arranging the side wall of the air outlet 231 of the volute 230 to be inclined towards the other one of the first side plate 211 and the second side plate 212 in the air outlet direction, the air outlet 231 of the volute 230 is in the form of a horn, so that the width of the air outlet end of the air outlet 231 of the volute 230 is substantially consistent with the width of the air supply channel 2141, which can guide the airflow to flow out more smoothly, reduce the turbulence of the airflow at the air outlet 231, and improve the stability and uniformity of the airflow.

[0090] Specifically, when the volute 230 is arranged on the first side plate 211, the air outlet 231 of the volute 230 is close to the side wall of the second side plate 212, and is inclined to the direction close to the second side plate 212 in the air outlet direction, so as to make the air volume on both sides of the air supply channel 2141 relatively uniform.

[0091] In addition, in the case that a plurality of air supply outlets 2144 distributed in the height direction are arranged on both sides of the shell 210, the air volume of the two air supply outlets 2144 at the same height can be made more uniform, and the adjustment is facilitated.

[0092] Referring to Figure 5 and Figure 8 , according to some embodiments of the present application, the end of the shell 210 for connecting with the rear wall 112 can be provided with an air supply pipe 2143 extending in the lateral direction, the air supply outlet 2144 can be arranged on the air supply pipe 2143, and the air outlet direction of the fan 240 can be arranged at an angle with the extension direction of the air supply pipe 2143.

[0093] Because the air supply outlet 2144 is arranged at the corner of the shell 210 connected with the rear wall 112, by arranging the air supply outlet 2144 on the air supply pipe 2143, the air supply pipe 2143 can play a good guiding role for the cold air, and can also guide the air supply direction of the air supply outlet 2144, so as to better supply air to the refrigeration cavity and improve the cooling effect. Exemplarily, the air supply pipe 2143 can be connected to the rear plate 214, and the side of the air supply pipe 2143 away from the rear wall 112, i.e. the front side of the air supply pipe 2143, is open to form the air supply outlet 2144.

[0094] Among them, because the fan 240 is arranged in the shell 210, by arranging the air outlet direction of the fan 240 at an angle with the extension direction of the air supply pipe 2143, the position of the fan 240 can be arranged more flexibly, the space occupied by the fan 240 is reduced, and the probability of interference between the fan 240 and other components is reduced.

[0095] Specifically, the air supply pipe 2143 extends in the lateral direction of the shell 210, i.e. the left-right direction, the air outlet direction of the fan 240 is opposite to the air supply channel 2141, and because the fan 240 is arranged on the front side of the air supply channel 2141, i.e. the air outlet direction of the fan 240 is backward, so that the air outlet direction of the fan 240 is perpendicular to the air supply pipe 2143.

[0096] Referring to Figure 4 , Figure 5 and Figure 7 , according to some embodiments of the present application, a plurality of air supply outlets 2144 can be arranged on both sides of the shell 210, and the plurality of air supply outlets 2144 on both sides are arranged symmetrically two by two; wherein the flow area of at least one pair of two air supply outlets 2144 at the same height is different.

[0097] In the case that the shell 210 is arranged in the middle of the inner container 110, both sides of the shell 210 can be provided with a plurality of air supply openings 2144 distributed along the height direction, and the plurality of air supply openings 2144 on both sides correspond one by one along the height direction, so that the cold air in the air supply channel 2141 is uniformly distributed in the air supply openings 2144 on both sides.

[0098] It can be understood that the flow area of the air supply opening 2144 determines the flow resistance thereof, and the characteristic of the fluid is that the smaller the resistance is, the higher the speed is, and the greater the flow is. Because of the limitation of the installation position of the fan 240 and the volute 230, and the complexity of air flow, it is difficult to ensure that the air volume of the air supply openings 2144 on both sides is consistent under the condition that the flow areas of the air supply openings 2144 are the same. By adjusting the flow areas of the two air supply openings 2144 at the same height to be different, the actual flow of the two air supply openings 2144 at the same height is relatively consistent, the uniformity of the cold quantity of the first chamber 120 and the second chamber 130 is improved, and the stability and use experience of the system are improved.

[0099] According to some embodiments of the present application, the thickness W of the refrigeration equipment 1000 in the depth direction of the refrigeration cavity can satisfy: 450mm≤W≤600mm.

[0100] The thickness of the refrigeration equipment 1000 is thin and has good aesthetics, which can better adapt to the indoor decoration of the user and improve the product quality. The thickness W of the refrigeration equipment 1000 in the depth direction of the refrigeration cavity is in the range of [450mm, 600mm], and exemplarily, W can take values of 450mm, 500mm, 550mm, 600mm or other values between 450mm and 600mm, and the specific values are not limited.

[0101] According to some embodiments of the present application, the thickness S of the door body can satisfy: 25mm≤S≤40mm.

[0102] The thickness of the door body of the refrigeration equipment 1000 is thin, light and convenient to open, and reduces the influence on the thickness of the entire refrigeration equipment 1000, so that the refrigeration equipment 1000 can be made thinner to better adapt to the indoor decoration of the user and improve the product quality. The thickness S of the door body is in the range of [25mm, 50mm], and exemplarily, S can take values of 25mm, 30mm, 35mm, 40mm or other values between 25mm and 40mm, and the specific values are not limited.
