[0056] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0057] Reference below Figure 1-Figure 13 An evaporation unit 100 for a storage device provided in an embodiment of the present application is described. The evaporation unit 100 includes a cover body 110 , an evaporator 120 , a fan assembly 130 and a water receiving member 140 .

[0058] It should be noted that the storage equipment in the embodiment can be understood as refrigeration storage equipment in a broad sense, including but not limited to refrigerators, freezers, display cabinets, beverage cabinets, wine cabinets, cold cabinets, and refrigerated vending machines and other refrigeration storage equipment. The storage equipment has various structural forms and a wide range of applications. As a specific example, the embodiment of the present application uses a vending cabinet as a specific example. The temperature of the compartment formed by the box body 400 of the vending cabinet can be lower than 0 degrees Celsius. In some embodiments, the temperature of the compartment of the vending cabinet can be -5°C to -30°C, such as -25°C. The vending cabinet is used to sell frozen goods, such as ice cream and ice cubes.

[0059] The housing 110 forms a receiving cavity 1101 having a return air port 1102, and the return air port 1102 is used to communicate with the compartment of the storage device. It should be noted that the size and shape of the receiving cavity 1101 and the return air port 1102 can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.

[0060] It is understandable that the accommodating chamber 1101 also has an air outlet 1103, that is, the high-temperature gas in the compartment flows into the accommodating chamber 1101 through the return air outlet 1102, and is converted into low-temperature gas after heat exchange with the evaporator 120, and then passes through the fan assembly 130 and flows from the air outlet 1103 through the air duct structure 200 of the storage device to flow into the compartment, forming an air path cycle, and achieving a cooling effect on the compartment. It should be noted that the size and shape of the air outlet 1103 can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.

[0061] The evaporator 120 is installed in the accommodating chamber 1101, and is used to cooperate with the compressor unit 300 to achieve a refrigeration effect to maintain the temperature in the room. The fan assembly 130 is installed in the accommodating chamber 1101, and is used to promote the circulation of the air path and improve the cooling efficiency. The return air port 1102, the evaporator 120 and the fan assembly 130 are arranged at intervals along the first direction.

[0062] For the convenience of the following description, the first direction refers to the front-to-back direction, that is, the width direction of the evaporator 120 ; the second direction refers to the up-down direction, that is, the height direction of the evaporator 120 ; the third direction refers to the left-to-right direction, that is, the length direction of the evaporator 120 .

[0063] It can be understood that the return air inlet 1102, the evaporator 120 and the fan assembly 130 are arranged in sequence from front to back. This layout optimizes space utilization, makes the structure of the evaporator unit 100 more compact, and can also ensure that the gas flowing into the accommodating chamber 1101 from the compartment needs to be cooled by the evaporator 120 first and then accelerated by the fan assembly 130 to flow back to the compartment, so as to achieve a more uniform and efficient cooling effect.

[0064] The water receiving member 140 is disposed in the accommodating chamber 1101 , and the projections of the evaporator 120 and the fan assembly 130 in the second direction are both located on the water receiving member 140 , and the first direction and the second direction intersect.

[0065] It can be understood that compared with the related art in which the fan assembly 130 is installed above or below the evaporator 120, causing the liquid generated during the operation of one of the fan assembly 130 or the evaporator 120 to drip onto the other of the fan assembly 130 or the evaporator 120, thereby affecting the operating efficiency of the evaporator unit 100 and even causing safety hazards such as circuit short circuit, the water receiving part 140 is arranged below the evaporator 120 and the fan assembly 130 to collect the liquid generated during the operation of the fan assembly 130 and the evaporator 120 respectively, thereby ensuring the normal operation of the evaporator 120 and the fan assembly 130, and further improving the safety of the storage device.

[0066] According to the evaporator unit 100 provided in the embodiment of the present application, on the one hand, the return air port 1102, the evaporator 120 and the fan assembly 130 are arranged at intervals along the first direction. This layout optimizes space utilization, making the structure of the evaporator unit 100 more compact, and can also ensure that the gas flowing into the accommodating chamber 1101 from the compartment needs to be cooled by the evaporator 120 first and then accelerated by the fan assembly 130 to flow back to the compartment, so as to achieve a more uniform and efficient cooling effect; on the other hand, since the projections of the evaporator 120 and the fan assembly 130 in the second direction are both located at the water receiving part 140, the water receiving part 140 can simultaneously collect the liquid generated by the fan assembly 130 and the evaporator 120 during operation, respectively, to ensure the normal operation of the evaporator 120 and the fan assembly 130, and further improve the safety of the use of the storage device.

[0067] In some embodiments, Figure 3 As shown, the fan assembly 130 is located behind the evaporator 120 , the water receiving member 140 is located below the fan assembly 130 and the evaporator 120 , and the return air port 1102 is provided on the front wall surface of the cover body 110 .

[0068] It can be understood that the gas in the compartment enters the accommodating chamber 1101 from front to back through the return air port 1102, and passes through the evaporator 120 and the fan assembly 130 in sequence. At the same time, the water receiving member 140 is used to collect the liquid generated during the operation of the fan assembly 130 and the evaporator 120, so as to make full use of the space in the accommodating chamber 1101, optimize the air flow path, improve the heat exchange efficiency, and facilitate the maintenance and management of the storage equipment.

[0069] In some embodiments, Figure 4 and Figure 5As shown, the evaporator 120 includes an evaporation tube 121, a plurality of first fins 122 arranged at intervals along the third direction, and a plurality of second fins 123 arranged at intervals along the third direction, and the evaporation tube 121 passes through each first fin 122 and each second fin 123; wherein the first fin 122 and the second fin 123 are arranged alternately along the third direction, and the projection of the first fin 122 along the third direction and the projection of the second fin 123 along the third direction partially overlap, and the overlapping area is arranged near the fan assembly 130, and the third direction intersects with the first direction and the second direction respectively. It should be noted that the number and shape of the first fin 122 and the second fin 123 can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.

[0070] It is understandable that the evaporation tube 121 is disposed in a curved shape in the accommodation chamber 1101, and a plurality of first fins 122 and a plurality of second fins 123 are arranged alternately in the left-right direction. Considering that the gas enters the accommodation chamber 1101 from the front to the back through the return air port 1102 and passes through the evaporator 120, that is, the temperature at the return air port 1102 is relatively high, while the temperature at the evaporation tube 121 is very low, by making the overlapping area of ​​the projection of the first fin 122 and the second fin 123 in the left-right direction close to the fan assembly 130, that is, the front part of the evaporation tube 121 is only provided with the first fin 122, and the rear part of the evaporation tube 121 is provided with the first fin 122 and the second fin 123, so that efficient heat exchange can be formed while reducing the risk of icing of the evaporator 120.

[0071] Exemplarily, the distance between two adjacent first fins 122 is 7.5-8 mm, and the distance between adjacent first fins 122 and second fins 123 is 4-5 mm, thereby avoiding the risk of icing at the rear of the evaporator tube 121 due to the temperature drop of the gas after heat exchange at the front of the evaporator tube 121.

[0072] In some embodiments, Figure 3 As shown, the evaporator 120 also includes an evaporation cover plate 124, which is located on a side of the evaporation tube 121 away from the water receiving member 140 and abuts against the first fin 122 and the second fin 123, and the projection of the first fin 122 along the second direction and the projection of the second fin 123 along the second direction are both located within the evaporation cover plate 124.

[0073] It is understandable that the lower surface of the evaporation cover plate 124 abuts against the upper end of the first fin 122 and the upper end of the second fin 123, respectively, to ensure the closeness and uniformity of the contact. The projections of the first fin 122 and the second fin 123 in the upper and lower directions are both located inside the evaporation cover plate 124, so that the evaporation cover plate 124 can completely cover the first fin 122 and the second fin 123 to form a heat exchange area that is as sealed as possible, which helps to maintain the uniformity of the air flow and temperature distribution in the evaporator 120, and reduce the turbulence during air flow, improve the heat exchange efficiency, and also reduce noise and vibration. In addition, when the first heating element 150 is installed on the front side of the evaporation tube 121, the efficiency of the heat transfer of the first heating element 150 to the rear side of the evaporation tube 121 can be accelerated, further accelerating the defrosting process.

[0074] In some embodiments, Figure 4 and Figure 5 As shown, the evaporator unit 100 further includes a first heating element 150 , which is located in the accommodating cavity 1101 and is arranged on a side of the evaporator 120 close to the return air port 1102 .

[0075] It can be understood that the first heating element 150 is installed on the front side of the evaporation tube 121, which is not only convenient for maintenance, but also can effectively preheat the evaporation tube 121, that is, at the beginning of the defrosting cycle, the heat of the first heating element 150 can be quickly transferred to the front of the evaporation tube 121, and then the heat is propagated backward along the evaporation tube 121, the first fin 122 and the second fin 123 until it reaches the rear side of the evaporation tube 121. At the same time, the heat generated by the first heating element 150 can be concentrated on the front side of the evaporation tube 121, which helps to reduce the total energy consumption required in the entire defrosting process, and can reach the temperature required for defrosting more quickly, thereby shortening the defrosting cycle and reducing energy waste.

[0076] In some embodiments, Figure 4 and Figure 5 As shown, the evaporator unit 100 also includes a plurality of connecting members 160, which are spaced apart in the left-right direction and are all sleeved on the outside of the evaporator tube 121. The plurality of connecting members 160 are in one-to-one contact with a portion of the plurality of first fins 122, which not only fixes the first heating member 150 while ensuring that the entire accommodating cavity 1101 is more compact, but also increases the heating area in contact with the first heating member 150, thereby further enhancing the defrosting effect.

[0077] In some embodiments, Figure 4 and Figure 5As shown, the fan assembly 130 includes a fan housing 131 and a fan body 132. The fan housing 131 forms an installation cavity with a water outlet 1311. The air inlet end of the fan housing 131 faces the evaporator 120, the air outlet end of the fan housing 131 faces the air outlet 1103 of the accommodating cavity 1101, and the water outlet 1311 faces the water receiving member 140. The fan body 132 is rotatably arranged in the installation cavity around the front and rear axes. It should be noted that the respective numbers and shapes of the water outlet 1311 and the fan body 132 can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.

[0078] It can be understood that the air inlet end of the fan housing 131 faces forward, the air outlet end of the fan housing 131 faces upward, and the water outlet 1311 is opened on the lower surface of the fan housing 131. The air inlet end of the fan housing 131 faces forward, that is, the gas is sucked into the installation cavity from front to back after being cooled by the evaporator 120, and is accelerated by the rotation of the fan body 132. The accelerated and cooled gas flows upward, which helps to push the cooled gas to the top of the compartment, so that the cooled gas naturally sinks in the compartment, forming an effective cooling cycle, and further enhancing the cooling effect. In addition, the water outlet 1311 is opened on the lower surface of the fan housing 131, which helps the liquid generated during the operation of the fan body 132 to be smoothly discharged to the water receiving member 140 through the water outlet 1311, avoiding the problem of water accumulation and potential corrosion of the fan assembly 130.

[0079] In some embodiments, Figure 5 As shown, the evaporator unit 100 further includes a second heating element 170 . The second heating element 170 is located in the accommodating cavity 1101 and is disposed on a side of the fan assembly 130 close to the evaporator 120 .

[0080] It is understandable that since the fan assembly 130 is disposed on the rear side of the evaporator 120, the second heating element 170 is disposed on the front surface of the fan housing 131, which is not only convenient for maintenance, but also can effectively preheat the fan assembly 130, reducing the risk of freezing of the fan assembly 130. At the same time, the second heating element 170 can heat the air in front of the fan housing 131, thereby accelerating the melting process of the frost on the rear side of the evaporation tube 121, reducing the defrosting cycle and energy waste.

[0081] In some embodiments, Figure 3 As shown, the water receiving member 140 is inclined in a direction away from the evaporator 120 along the third direction.

[0082] It can be understood that the water receiving member 140 is tilted downward as a whole in the left-right direction, so that the relatively lower end of the water receiving member 140 in the left-right direction is close to the compressor unit 300 of the refrigeration system, so as to more effectively collect the defrost water generated by the evaporator 120 and the fan assembly 130 during operation.

[0083] In this embodiment, Figure 3 As shown, the compressor unit 300 is located on the right side of the evaporator unit 100, and the water receiving member 140 is inclined downward from left to right.

[0084] In some embodiments, Figure 3 As shown, a relatively lower end of the water receiving member 140 in the left-right direction is provided with a water outlet hole 141, one end of the drainage pipe of the refrigeration system is installed in the water outlet hole 141, and the other end is installed in the water receiving tray outside the evaporator unit 100, so as to reuse the defrost water later. In this embodiment, the water outlet hole 141 is opened on the right wall of the water receiving member 140.

[0085] In some embodiments, Figure 3 As shown, the inclination angle range of the water receiving member 140 is 3-6°, that is, when the angle between the lower surface of the water receiving member 140 and the inner lower wall of the accommodating chamber 1101 is less than 3°, the defrost water in the water receiving member 140 is difficult to flow out due to the surface tension of the defrost water, and is easy to gather and cause ice, and even cause the evaporator 120 to freeze, affecting the refrigeration effect; when the angle between the lower surface of the water receiving member 140 and the inner lower wall of the accommodating chamber 1101 is greater than 6°, although the water receiving member 140 drains smoothly, the gap between the water receiving member 140 and the lower end of the evaporator 120 is too large, so that the gas flowing into the accommodating chamber 1101 from the return air port 1102 is easy to not exchange heat with the evaporator 120, and directly enter the fan assembly 130 from the gap, resulting in poor refrigeration effect, and even causing the evaporator 120 to freeze, affecting the refrigeration effect.

[0086] In some embodiments, Figure 3 As shown, the water receiving member 140 has a water receiving surface 142 facing the evaporator 120 , and the water receiving surface 142 is inclined from both sides of the first direction to the middle along a direction away from the evaporator 120 .

[0087] It can be understood that the front side of the water receiving surface 142 is inclined downward toward the middle, and the rear side of the water receiving surface 142 is inclined downward toward the middle, so that the distance between the middle of the water receiving surface 142 and the evaporator 120 along the up and down direction is greater than the distance between the front and back sides of the water receiving surface 142 and the evaporator 120 along the up and down direction, thereby ensuring that the defrost water can be concentrated in the middle of the water receiving surface 142 before flowing to the drain pipe, thereby improving the drainage effect. At the same time, the inclined water receiving surface 142 helps to maintain the air flow inside the accommodating cavity 1101, prevent airflow obstruction caused by water accumulation, and thus maintain the cooling efficiency of the evaporator 120.

[0088] In some embodiments, Figure 3As shown, the cover body 110 includes a support seat 111, a side enclosure member 112 and a cover member 113, and the water receiving member 140 is installed on the support seat 111; the side enclosure member 112 and the water receiving member 140 are spaced apart along the second direction, the evaporator 120 and the fan assembly 130 are both installed in the side enclosure member 112, and the return air port 1102 is arranged in the side enclosure member 112; the cover member 113, the side enclosure member 112 and the support seat 111 are sequentially connected along the second direction to form a accommodating cavity 1101.

[0089] It is understandable that the support seat 111 forms a mounting groove with an opening facing upward, and the bottom of the mounting groove is tilted so that the water receiving member 140 can be tilted downward along the left-right direction as a whole. The upper and lower ends of the side enclosure member 112 are open and installed on the support seat 111, which not only provides lateral support for the evaporator 120 and the fan assembly 130, but also forms a return air port 1102 to ensure the realization of gas heat exchange in the compartment and the accommodating chamber 1101. The cover member 113, the side enclosure member 112 and the support seat 111 are connected in sequence from top to bottom and are jointly arranged to form a relatively closed accommodating chamber 1101, which protects the evaporator 120 and the fan assembly 130 from external influences as much as possible, and also helps to control the gas and temperature inside the accommodating chamber 1101.

[0090] In some embodiments, Figure 1 and Figure 6 As shown, the side enclosure member 112 has a windward surface 1121 , and the return air port 1102 is disposed on the windward surface 1121 . The windward surface 1121 is inclined from a direction close to the water receiving member 140 to a direction away from the evaporator 120 .

[0091] It can be understood that the front surface of the side enclosure 112 includes a windward surface 1121, and the windward surface 1121 is inclined forward from top to bottom. The inclined windward surface 1121 helps to guide the air to enter the accommodating cavity 1101 more smoothly, reduce the resistance to gas flow, improve the efficiency of gas flow, and increase the contact area between the gas and the windward surface 1121, which helps to improve the efficiency of heat exchange and facilitates cleaning and maintenance.

[0092] In some embodiments, Figure 1 and Figure 6 As shown, the inclination angle of the windward surface 1121 ranges from 40° to 60°, so as to maximize the heat exchange efficiency and the smoothness of the air circulation.

[0093] In some embodiments, Figure 1 As shown, the projection of the side enclosure member 112 along the second direction partially overlaps with the projection of the support seat 111 along the second direction, and the overlapping area is arranged close to the fan assembly 130 .

[0094] It can be understood that the overlapping area of ​​the projections of the side enclosure 112 and the support seat 111 in the up and down directions is close to the rear part of the side enclosure 112, that is, the front part of the side enclosure 112 protrudes forward compared to the support seat 111, that is, the lower edge of the windward surface 1121 is located in front of the upper edge of the front surface of the support seat 111 so that an air inlet is formed between the side enclosure 112 and the support seat 111, and part of the gas in the compartment can directly enter the accommodating cavity 1101 from the air inlet, so as to improve the gas exchange efficiency between the compartment and the accommodating cavity 1101.

[0095] In some embodiments, Figure 1 , Figure 3 , Figure 6 and Fig. 9 As shown, the cover body 110 also includes a guide member 114 arranged outside the return air port 1102, and the side of the guide member 114 close to the cover member 113 is connected to the windward surface 1121, and the side of the guide member 114 away from the cover member 113 is spaced apart from the windward surface 1121.

[0096] It can be understood that the guide member 114 corresponds to the return air port 1102 one by one, the upper side of the guide member 114 is connected to the windward surface 1121, and the lower side of the guide member 114 is located in front of the windward surface 1121. A rectifying channel 203 is formed between the guide member 114 and the windward surface 1121, so that the gas in the compartment needs to enter the rectifying channel 203 obliquely upward and enter the accommodating chamber 1101 through the return air port 1102. Taking into account the principle of upward movement of hot air, the hot air generated by the first heating element 150 during defrosting can be discharged into the compartment through the return air port 1102 and the rectifying channel 203 as much as possible.

[0097] In some embodiments, Figure 1 , Figure 3 , Figure 6 and Fig. 9 As shown, the side of the guide member 114 away from the windward surface 1121 is arc-shaped, and the center of its curvature is located on the side facing the windward surface 1121, so that the gas can flow smoothly, reduce turbulence during air flow, improve the efficiency of air flow, and reduce the accumulation of condensed water on the surface of the guide member 114.

[0098] In some embodiments, Figure 3 and Fig. 9 As shown, the evaporator compartment 410 further includes a seal 180, which is located in the accommodating chamber 1101 and is sealedly connected to the inner wall of the accommodating chamber 1101, the evaporator 120 and the fan assembly 130, respectively, so as to allow the gas entering the accommodating chamber 1101 from the return air port 1102 to pass through the evaporator 120 and the air inlet of the fan assembly 130 in sequence along the first direction. The material of the seal 180 includes but is not limited to foam.

[0099] It is understandable that, considering that the central axis of the fan assembly 130 may not be at the same height as the central axis of the evaporator 120, the seal 180 is placed in the space formed by positioning the fan assembly 130 at the front surface portion above the air inlet end of the fan assembly 130, above the evaporator 120 and the upper inner portion of the accommodating chamber 1101, thereby ensuring that the gas flowing from the compartment into the accommodating chamber 1101 needs to pass through the evaporator 120 for heat exchange before entering the fan assembly 130, thereby improving the heat exchange efficiency.

[0100] In some embodiments, Figure 3 As shown, the seal 180 includes at least two sealing parts that are sequentially plugged in along the left and right directions, thereby facilitating installation and optimizing the process. It should be noted that the number and shape of the sealing parts can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.

[0101] In some embodiments, Figure 7 As shown, the evaporation unit 100 is configured to be installed in the cabinet 400 of the storage device along the left-right direction, and the evaporation unit 100 is located at the rear of the cabinet 400 .

[0102] It is understandable that the evaporator unit 100 is installed in the box body 400 along the left-right direction, that is, when installed, the evaporator unit 100 is pushed from the left side of the box body 400 to the right side until one end of the drain pipe is clamped in the water outlet 141 of the water receiving member 140, which is convenient for maintenance and cleaning. At the same time, the evaporator unit 100 is located at the rear of the box body 400, so that the evaporator unit 100 is located at the lower side of the compartment, so that the cargo channel in the compartment can be placed above the evaporator unit 100, and the lifting structure for moving the goods can be movably arranged at the front side of the evaporator unit 100, so as to further make the structure of the entire storage device more compact.

[0103] In some embodiments, Figures 1 to 3 and Figure 7 As shown, the evaporator unit 100 further includes a reinforcement member 190, which is installed on the left side of the cover body 110 to resist deformation of the evaporator unit 100 caused by vibration or other external forces during operation, thereby improving the stability and durability of the structure of the evaporator unit 100. The material of the reinforcement member 190 includes but is not limited to foam.

[0104] The present application also provides a refrigeration system. Figure 7 As shown, the refrigeration system includes a compressor unit 300 and the above-mentioned evaporator unit 100, the compressor unit 300 is located in the cabin 410 of the storage device; and the evaporator unit 100 is located in the refrigeration cabin of the storage device and is used for heat exchange with the compressor unit 300.

[0105] According to the refrigeration system provided in the embodiment of the present application, the return air port 1102, the evaporator 120 and the fan assembly 130 in the evaporator unit 100 are arranged at intervals along the first direction. This layout optimizes space utilization, makes the structure of the evaporator unit 100 more compact, and can also ensure that the gas flowing into the accommodating chamber 1101 from the compartment needs to be cooled by the evaporator 120 first and then accelerated by the fan assembly 130 to flow back to the compartment, so as to achieve a more uniform and efficient cooling effect; on the other hand, since the projections of the evaporator 120 and the fan assembly 130 in the evaporator unit 100 in the second direction are both located at the water receiving part 140, the water receiving part 140 can simultaneously collect the liquid generated by the fan assembly 130 and the evaporator 120 during operation, respectively, to ensure the normal operation of the evaporator 120 and the fan assembly 130, and further improve the safety of the storage device.

[0106] In some embodiments, Figure 7 As shown, the box body 400 also forms a refrigeration chamber and a machine chamber 410, and the refrigeration system further includes a compressor unit 300, which is located in the machine chamber 410, and the evaporator unit 100 is located in the refrigeration chamber, and the evaporator unit 100 and the compressor unit 300 are distributed in the left and right directions.

[0107] It can be understood that the refrigeration chamber is located at the rear of the box body 400, that is, the refrigeration chamber is located at the lower side of the compartment, so that the cargo aisle in the compartment can be placed above the refrigeration chamber, and the lifting structure for moving goods can be movably arranged on the front side of the evaporator unit 100, and the refrigeration chamber is located on the left side of the cabin 410, thereby further making the structure of the entire storage device more compact and improving the commodity storage capacity of the storage device.

[0108] In some embodiments, Figures 7 to 13 As shown, the refrigeration system also includes a duct structure 200, which forms an air supply duct 201 and multiple guide channels. The air supply duct 201 is respectively connected to the accommodating cavity 1101 and the guide channel, the guide channel is connected to the compartment, and the air outlet directions of at least two guide channels are different.

[0109] It can be understood that the air supply duct 201 extends in the up-down direction, that is, the gas in the compartment enters the accommodating chamber 1101 through the return air port 1102 and exchanges heat with the evaporator 120, then passes through the fan assembly 130 and enters the air supply duct 201 through the air outlet 1103 of the accommodating chamber 1101, and finally flows back to the compartment through each guide channel to form an air circulation, ensuring that the air can be evenly distributed throughout the compartment, which helps to improve the uniformity and efficiency of cooling. At the same time, at least two guide channels have different air outlet directions, which helps the gas enter the compartment from different directions and flow to different areas of the compartment, thereby achieving a more uniform cooling effect and achieving an efficient cooling effect.

[0110] In some embodiments, Figures 7 to 10 As shown, some of the plurality of guide channels are arranged at intervals in a direction close to the evaporator unit 100 .

[0111] It can be understood that some of the multiple guide channels are arranged at intervals in the up and down directions, so that the gas can be distributed in areas at different heights, which helps to form a uniform temperature distribution in the compartment, reduce the temperature gradient, thereby improving the cooling efficiency, optimizing the flow path of the gas in the compartment, reducing the ineffective flow and heat loss of the gas, and helping to improve the energy efficiency ratio of the storage equipment.

[0112] In some embodiments, Figures 7 to 10 As shown, some of the plurality of guide channels are arranged at intervals along the third direction.

[0113] It should be noted that a plurality refers to two or more.

[0114] It can be understood that some of the multiple guide channels are arranged at intervals in the left and right directions, so that the gas can diffuse rapidly after entering the compartment and cover a wider area, which helps to form a uniform temperature distribution in the compartment and reduce the temperature gradient, thereby improving the cooling efficiency, optimizing the flow path of the gas in the compartment, reducing the ineffective flow of the gas and heat loss, and helping to improve the energy efficiency ratio of the storage equipment.

[0115] In this embodiment, Figures 7 to 10 As shown, some of the multiple guide channels are arranged at intervals along the direction close to the evaporator unit 100, and some of the multiple guide channels are arranged at intervals along the direction close to the evaporator unit 100, that is, the multiple guide channels are distributed in an array, ensuring that the gas is evenly distributed in the entire compartment and avoiding the occurrence of cooling dead corners.

[0116] In some embodiments, Figures 7 to 10 As shown, the air outlet direction of at least one guide channel close to the evaporator unit 100 is toward the opening of the compartment.

[0117] It can be understood that the air outlet direction of the guide channel at the bottom is forward. Considering that the temperature at the return air outlet 1102 of the evaporator unit 100 is relatively high, the cooled gas can be quickly delivered to the part of the compartment close to the evaporator unit 100, thereby improving the cooling efficiency and ensuring uniform temperature in the entire compartment.

[0118] In some embodiments, Figures 7 to 10 As shown, the air outlet direction of at least one guide channel away from the evaporator unit 100 is toward the inner side wall of the compartment arranged along the third direction, and the third direction intersects with the arrangement direction of the guide channel.

[0119] It is understandable that the air outlet direction of the guide channel at the top is toward the left or right wall of the compartment, which helps to guide the cooled gas directly to the left or right wall of the compartment, realize directional cooling, and reduce the discomfort of the user when the gas blows directly to the opening of the compartment. At the same time, the gas will rebound after contacting the left or right wall, thereby forming a circulation flow in the compartment, which helps to improve the uniformity of air flow and reduce cooling dead corners. In addition, considering the principle of upward movement of hot air, especially in large or high storage equipment, cold air may tend to sink, resulting in a higher temperature in the upper area of ​​the compartment. Supplying air to the left or right wall through the guide channel located at the top can reduce the temperature stratification phenomenon, optimize the flow path of the gas in the compartment, reduce the ineffective flow of the gas and heat loss, and help improve the energy efficiency ratio of the storage equipment.

[0120] In some embodiments, Figures 7 to 10 As shown, the air outlet directions of the guide channels located on both sides of the third direction are respectively toward two oppositely arranged inner side walls of the compartment.

[0121] It can be understood that the air outlet direction of the upper and left-side guide channel is toward the left wall of the compartment, and the air outlet direction of the upper and right-side guide channel is toward the right wall of the compartment, which helps to deliver the gas directly to the left and right walls of the compartment at the shortest distance. When the gas flows to the left and right walls, convection along the wall surface can be formed, which helps to evenly distribute the temperature and reduce uneven cooling, and can also reduce the vertical temperature stratification caused by the difference in air density in the compartment, ensuring the consistency of the temperature in the entire compartment.

[0122] In this embodiment, Figures 7 to 10 As shown, two guide channels are arranged at intervals along the left-right direction to form a channel group, and multiple channel groups are arranged at intervals along the up-down direction. The air outlet direction of the guide channel in the lowest channel group faces forward, and the air outlet direction of the guide channels in the remaining channel groups faces the left and right side walls of the compartment.

[0123] In some embodiments, Figures 7 to 13As shown, the guide channel includes a plurality of sub-channels 2021 spaced apart along the third direction, the duct structure 200 includes a duct shell 210 and a plurality of guide components 220 corresponding to the air outlet holes one by one, the duct shell 210 forms an air supply duct 201, and a plurality of air outlet holes are provided on one side of the duct shell 210 close to the evaporator unit 100; the guide component 220 includes a mounting member 221 and a plurality of partitions 222, the mounting member 221 is mounted on the duct shell 210 and has mounting holes, the mounting holes correspond to and are connected to the air outlet holes one by one, and a plurality of partitions 222 are spaced apart along the third direction at the mounting holes, and a sub-channel 2021 is formed between two adjacent partitions 222 and the inner edge of the mounting hole. It should be noted that the number and size of the partitions 222 can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.

[0124] It is understandable that the air duct shell 210 forms an air supply duct 201 extending in the up-down direction, and the front wall of the air duct shell 210 begins to have a plurality of air outlets, and the mounting member 221 is mounted at the air outlet, and the mounting hole and the air outlet are connected to ensure that the gas can flow smoothly from the air supply duct 201 into the guide channel. A plurality of partitions 222 are arranged in the mounting hole at intervals along the left-right direction, so that the formed plurality of sub-channels 2021 are also distributed at intervals along the left-right direction, thereby increasing the path of gas flow and helping to improve the uniformity of gas distribution. The sub-channels 2021 are formed between two adjacent partitions 222 and the inner edge of the mounting hole, that is, the gas flows from the sub-channels 2021 and along the surface of the partition 222 to different directions of the compartment.

[0125] In some embodiments, Fig.11 As shown, the partitions 222 of some of the plurality of guide components 220 are inclined toward the third direction along the opening of the compartment.

[0126] It can be understood that the partitions 222 of some guide components 220 are inclined from back to front and to the left and right, that is, the partitions 222 of the guide channel on the upper part and on the left are inclined from back to front and to the left, so that the air outlet direction of the corresponding guide channel is toward the left side wall of the compartment; the partitions 222 of the guide channel on the upper part and on the right are inclined from back to front and to the right, so that the air outlet direction of the corresponding guide channel is toward the right side wall of the compartment.

[0127] In some embodiments, Fig.12 and Fig.13As shown, the air duct structure 200 also includes a rectifying member 223, and some of the multiple guide assemblies 220 are provided with rectifying members 223, and the rectifying member 223 is located in the air supply duct 201, and the side of the rectifying member 223 away from the evaporator unit 100 is connected to the mounting member 221, and the side of the rectifying member 223 close to the evaporator unit 100 is spaced apart from the mounting member 221 along the first direction, and one side of the partition 222 extends into the air supply duct 201 through the mounting hole and is connected to the rectifying member 223, and the first direction and the third direction intersect.

[0128] It is understandable that the guide assembly 220 located at the bottom is provided with a corresponding rectifying piece 223, the upper side of the rectifying piece 223 is connected to the part of the mounting piece 221 located in the air supply duct 201, and the lower side of the rectifying piece 223 is located behind the mounting piece 221. A guide channel is formed between the rectifying piece 223 and the mounting piece 221 to improve the direction and speed of gas flow, so that the gas in the air supply duct 201 needs to enter the guide channel obliquely upward and enter the compartment through the guide channel, which helps to pre-rectify the gas flowing out of the air supply duct 201 and reduce the turbulence of gas flow. At the same time, the rear side of the partition 222 extends into the air supply duct 201 through the mounting hole and is connected to the rectifying piece 223, which not only enhances the stability of the guide assembly 220, but also helps to form a more orderly airflow.

[0129] In this embodiment, Figure 8 , Fig.10 , Fig.12 and Fig.13 As shown, the two flow guide components 220 at the bottom are both provided with flow straighteners 223 to ensure that the gas can flow forward from the sub-channel 2021 into the compartment more smoothly.

[0130] In some embodiments, Fig.12 and Fig.13 As shown, a surface of the fairing 223 away from the mounting member 221 includes an arcuate surface, and the center of curvature of the arcuate surface is located on the side of the arcuate surface facing the mounting hole.

[0131] It is understandable that the rear surface of the fairing 223 is an arc-shaped surface, which helps to smooth the gas flow and effectively guide the gas flow. In addition, the center of curvature of the arc-shaped surface is located on the side of the arc-shaped surface facing the mounting hole, so that the gas can naturally enter the sub-channel 2021 along the front surface of the fairing 223, reducing the sudden change and vortex of the gas.

[0132] In some embodiments, Figure 7 As shown, the air duct structure 200 is connected to the evaporator unit 100 and is located above the evaporator unit 100 .

[0133] It can be understood that the lower part of the air duct shell 210 is connected to the upper part of the cover plate 113, so that the air outlet 1103 of the cover body 110 is located in the air supply duct 201, so as to realize the connection between the air supply duct 201 and the accommodating cavity 1101, minimize the distance of gas flow, improve the cooling efficiency, and achieve more energy-saving operation.

[0134] The present application also provides a storage device. Figure 7 As shown, the storage device includes a box body 400 and the above-mentioned refrigeration system, the box body 400 forms a compartment, and the refrigeration system is used to provide cold air to the compartment.

[0135] It should be noted that the storage equipment in the embodiment can be understood as refrigeration storage equipment in a broad sense, including but not limited to refrigerators, freezers, display cabinets, beverage cabinets, wine cabinets, cold cabinets, and refrigerated vending machines and other refrigeration storage equipment. The storage equipment has various structural forms and a wide range of applications. As a specific example, the embodiment of the present application uses a vending cabinet as a specific example. The temperature of the compartment formed by the box body 400 of the vending cabinet can be lower than 0 degrees Celsius. In some embodiments, the temperature of the compartment of the vending cabinet can be -5°C to -30°C, such as -25°C. The vending cabinet is used to sell frozen goods, such as ice cream and ice cubes.

[0136] According to the storage device provided in the embodiment of the present application, the return air port 1102, the evaporator 120 and the fan assembly 130 in the evaporator unit 100 of the refrigeration system are arranged at intervals along the first direction. This layout optimizes space utilization, makes the structure of the evaporator unit 100 more compact, and can also ensure that the gas flowing into the accommodating chamber 1101 from the compartment needs to be cooled by the evaporator 120 first and then accelerated by the fan assembly 130 to flow back to the compartment, so as to achieve a more uniform and efficient cooling effect; on the other hand, since the projections of the evaporator 120 and the fan assembly 130 in the evaporator unit 100 in the second direction are both located at the water receiving part 140, the water receiving part 140 can simultaneously collect the liquid generated by the fan assembly 130 and the evaporator 120 during operation, respectively, to ensure the normal operation of the evaporator 120 and the fan assembly 130, and further improve the safety of the use of the storage device.

[0137] In some embodiments, the storage device is a vending machine, and the refrigeration system is used to provide cold air to the compartment so that the temperature of the compartment is suitable to be below zero degrees.

[0138] It is understood that the compartment can constitute at least one of a normal temperature room, a cold storage room or a freezing room, and the normal temperature room can be cooled to form a cold storage room, the cold storage room can be further cooled to form a freezing room, and the freezing room can be heated to form a cold storage room. When the refrigeration system is used to provide coldness to the compartment so that the temperature of the compartment is suitable for being below zero degrees Celsius, the items in the room are frozen at this time, and the compartment constitutes a freezing room. When the refrigeration system is used to provide coldness to the compartment so that the temperature of the compartment is suitable for being above 0 degrees Celsius and below 9 degrees Celsius, the compartment constitutes a cold storage room at this time. When the refrigeration system is not running, the compartment constitutes a normal temperature room.
