[0060] Hereinafter, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily implement them. In addition, for the sake of clarity, parts not related to the description of the exemplary embodiments are omitted in the accompanying drawings.

[0061] In the present disclosure, it should be understood that terms such as "including" or "having" are intended to indicate the presence of features, numbers, steps, behaviors, components, parts, or combinations thereof disclosed in the present specification, and do not exclude the possibility that one or more other features, numbers, steps, behaviors, components, parts, or combinations thereof exist or are added.

[0062] It should also be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present disclosure may be combined with each other. The present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0063] As mentioned above, with the development of technology and the improvement of people's living standards, in recent years, businesses or enterprises can place items that need to be kept above or below the ambient temperature (such as hot drinks and snacks sold in winter, cold drinks and chocolate sold in summer, etc.) in a temperature-controlled cabinet with a temperature control function to store the items. During the operation of the temperature-controlled cabinet, in order to ensure that the temperature of the stored items can be maintained within the temperature range that meets the user's needs, the temperature control system of the temperature-controlled cabinet needs to perform cooling or heating work to control the temperature of the storage area for storing items in the temperature-controlled cabinet to maintain a certain temperature difference with the temperature outside the temperature-controlled cabinet. When the user opens the temperature-controlled cabinet and takes out the corresponding items, the temperature of the items can meet the user's needs.

[0064] In one embodiment, to control the temperature of items in the storage area, the temperature-controlled cabinet can introduce air into the storage area at a temperature slightly different from the ambient temperature of the temperature-controlled cabinet, thereby allowing the items in the storage area to undergo heat exchange with the air introduced into the storage area, thereby achieving the purpose of temperature control of the items in the storage area. An air outlet can be provided near the bottom of the storage area, through which air at a temperature slightly different from the ambient temperature of the temperature-controlled cabinet is introduced into the storage area.

[0065] However, in this solution, since air with a certain temperature difference from the ambient temperature of the temperature-controlled cabinet is introduced into the storage area through the air outlet near the bottom of the storage area, the air introduced into the storage area through the air outlet will first flow to the bottom of the storage area through the air outlet, and the items in the storage area near the bottom of the storage area will first exchange heat with the air introduced into the storage area. After that, as the air flows, the items in the storage area far from the bottom of the storage area (i.e., the items in the upper middle part of the storage area) can exchange heat with the air introduced into the storage area. Since the air introduced into the storage area has already exchanged heat with the items near the bottom of the storage area at this time, the temperature of the air introduced into the storage area may also have changed to a certain extent (i.e., it may change towards the direction of being closer to the ambient temperature). Therefore, the effect of heat exchange between the air introduced into the storage area and the items in the storage area far from the bottom of the storage area is less than the effect of heat exchange between the air introduced into the storage area and the items in the storage area near the bottom of the storage area. Considering that the height of the items located near the bottom of the storage area from the ground is much lower than the height at which users can comfortably pick up items, the probability that the items located near the bottom of the storage area are taken out by users first is low, and the probability that the temperature difference between the temperature of the items taken out from the storage area by users is large and the temperature required by users is high, which may damage the user experience.

[0066] Therefore, how to ensure that the temperature of the items that users take out first in the temperature-controlled cabinet is close to the temperature required by the users is an increasingly urgent problem that needs to be solved.

[0067] In view of the above-mentioned defects, in one embodiment of the present disclosure, a temperature-controlled cabinet is proposed, which includes an evaporator and at least one first air outlet, wherein the first air outlet is arranged in the storage area of ​​the temperature-controlled cabinet and is connected to the air outlet of the evaporator, and the first air outlet is used to allow the air flowing out of the air outlet of the evaporator to flow to the article entrance and exit of the storage area through the first air outlet, and articles can be moved into or out of the storage area through the article entrance and exit, so that the air flowing out of the air outlet of the evaporator can directly flow to the articles in the storage area located near the article entrance and exit, shortening the time difference between the moment when the air flows out from the air outlet of the evaporator and the moment when this part of the air (i.e., the air flowing out of the air outlet of the evaporator) flows to the articles near the article entrance and exit, so that the air flowing out of the air outlet of the evaporator can exchange heat with the articles near the article entrance and exit as soon as possible, thereby improving the effect of temperature control of the articles near the article entrance and exit, thereby ensuring that the temperature of the articles near the article entrance and exit can be close to the temperature required by the user, and improving the user experience.

[0068] The temperature-controlled cabinet provided in the embodiment of the present application may have a temperature control function, which may be a cooling function, for example, the temperature-controlled cabinet may be a refrigerated temperature-controlled cabinet, a frozen temperature-controlled cabinet, a refrigerator, a freezer, a refrigerator, a wine cabinet, a cosmetics preservation cabinet, etc.; the temperature-controlled function may also be a heating function, for example, the temperature-controlled cabinet may be a warming cabinet, a heating temperature-controlled cabinet, a hot drink cabinet, etc. The embodiment of the present application does not impose any restrictions on the specific type of the temperature-controlled cabinet.

[0069] For example, Figure 1 A schematic structural block diagram of a temperature control system in a temperature control cabinet according to an embodiment of the present disclosure is shown. Figure 1 As shown, the temperature control system 100 may include a compressor 11, a condenser 12, a throttling element 13 and an evaporator 14, wherein the compressor 11, the condenser 12, the throttling element 13 and the evaporator 14 are connected by pipes filled with refrigerant to form a closed pipeline, constituting a temperature control system or heating system capable of circulating refrigerant.

[0070] Among them, the compressor refers to a driven fluid machinery used to increase the low-pressure refrigerant to high-pressure refrigerant. The compressor can absorb low-temperature and low-pressure gaseous refrigerant, compress the refrigerant by driving the piston through the operation of the motor, and then discharge the high-temperature and high-pressure gaseous refrigerant to provide power for the refrigeration cycle. The compressor can include reciprocating compressors, screw compressors, rotary compressors, scroll compressors and centrifugal compressors, etc. The embodiments of this application do not impose any restrictions on the specific types of compressors.

[0071] The condenser refers to a heat exchanger used to exchange heat between the refrigerant in the condenser and the air outside the condenser to achieve heat release. Specifically, the condenser may include a long pipe for accommodating the refrigerant, which may usually be made of a metal material with strong thermal conductivity such as copper, and the pipe may usually be coiled into a spiral shape. In addition, in order to improve the heat exchange efficiency of the condenser, a heat sink with excellent thermal conductivity may be provided on the pipe to increase the heat dissipation area, thereby accelerating the speed of heat exchange and improving the heat exchange efficiency. It is also possible to provide a blower or fan that matches the condenser to speed up the flow of air around the condenser, thereby accelerating the speed of heat exchange and improving the heat exchange efficiency.

[0072] The throttling element is used to throttle the liquid refrigerant at room temperature and high pressure through the throttling element to become a gas refrigerant at low temperature and low pressure, wherein the throttling element can also be called a throttling element or a regulating valve, and the throttling element can include an expansion valve, a capillary tube, etc. In addition, the throttling element can also control the flow of the refrigerant flowing through the throttling element to avoid the flow of the refrigerant flowing through the throttling element being too large or too small. Among them, if the flow of the refrigerant flowing through the throttling element is too large, the refrigerant flowing out of the throttling element will still include liquid refrigerant, and the liquid refrigerant will enter the compressor to cause liquid hammer, causing damage to the compressor; if the flow of the refrigerant flowing through the throttling element is too small, it will cause too little refrigerant to enter the compressor, reducing the working efficiency of the compressor.

[0073] The evaporator refers to a heat exchanger used to exchange heat between the refrigerant in the evaporator and the air outside the condenser to achieve heat absorption. Specifically, the evaporator may include a long pipe for accommodating the refrigerant. The pipe can usually be made of a metal material with strong thermal conductivity such as copper, and the pipe can usually be coiled into a spiral shape. In addition, in order to improve the heat exchange efficiency of the condenser, a heat sink with excellent thermal conductivity can be provided on the pipe to increase the heat dissipation area, thereby accelerating the speed of heat exchange and improving the heat exchange efficiency. It is also possible to provide a blower or fan that matches the evaporator to speed up the flow of air around the evaporator, thereby accelerating the speed of heat exchange and improving the heat exchange efficiency.

[0074] Refrigerant, which can also be called refrigerant, coolant or refrigerant, is a medium substance that completes energy conversion in the temperature control system or heating system. Refrigerant is usually a substance that easily undergoes reversible phase change (such as absorbing heat to become a gas, releasing heat to become a liquid). Through reversible phase change, the refrigerant can transfer heat. Specifically, when the gaseous refrigerant is under pressure, it releases heat and becomes a liquid. When the high-pressure liquid is decompressed and becomes a gas, it absorbs heat. Refrigerants can include ammonia, air, water, salt water, Freon (also known as chlorofluorocarbons, chlorofluorocarbons), etc., among which Freon can include monochlorotrifluoromethane, dichlorodifluoromethane, trifluoromethane, tetrafluoroethane, trichlorodifluoroethane, etc.

[0075] When the temperature control cabinet is a temperature control cabinet with a refrigeration function, the low-temperature and low-pressure gaseous refrigerant flows from the evaporator into the compressor, which compresses the low-temperature and low-pressure gaseous refrigerant and makes the high-temperature and high-pressure gaseous refrigerant flow into the condenser; the high-temperature and high-pressure gaseous refrigerant exchanges heat with the air outside the condenser through the condenser, so that the high-temperature and high-pressure gaseous refrigerant is cooled into a normal-temperature and high-pressure liquid refrigerant in the condenser, and then the normal-temperature and high-pressure liquid refrigerant flows into the throttling element, and the throttling element throttles the normal-temperature and high-pressure liquid refrigerant, so that the refrigerant flowing out of the throttling element is converted into a low-temperature and low-pressure liquid refrigerant; the low-temperature and low-pressure liquid refrigerant flows into the evaporator, and the low-temperature and low-pressure liquid refrigerant exchanges heat with the air outside the evaporator through the evaporator, and the low-temperature and low-pressure liquid refrigerant evaporates and vaporizes into a low-temperature and low-pressure gaseous refrigerant to absorb heat. Among them, the air outside the evaporator can be introduced into the storage area of ​​the temperature-controlled cabinet, and the air outside the condenser can be introduced into the outside of the temperature-controlled cabinet, thereby transferring the heat in the storage area of ​​the temperature-controlled cabinet to the outside of the temperature-controlled cabinet to cool the storage area of ​​the temperature-controlled cabinet.

[0076] When the temperature control cabinet is a temperature control cabinet with heating function, the low-temperature and low-pressure gaseous refrigerant flows from the condenser into the compressor, which compresses the low-temperature and low-pressure gaseous refrigerant and makes the high-temperature and high-pressure gaseous refrigerant flow into the evaporator; the high-temperature and high-pressure gaseous refrigerant exchanges heat with the air outside the evaporator through the evaporator, so that the high-temperature and high-pressure gaseous refrigerant is cooled into a normal-temperature and high-pressure liquid refrigerant in the evaporator, and then the normal-temperature and high-pressure liquid refrigerant flows into the throttling element, and the throttling element throttles the normal-temperature and high-pressure liquid refrigerant, so that the refrigerant flowing out of the throttling element is converted into a low-temperature and low-pressure liquid refrigerant; the low-temperature and low-pressure liquid refrigerant flows into the condenser, and the low-temperature and low-pressure liquid refrigerant exchanges heat with the air outside the condenser through the condenser, and the low-temperature and low-pressure liquid refrigerant evaporates and vaporizes into a low-temperature and low-pressure gaseous refrigerant to absorb heat. Among them, the air outside the evaporator can be introduced into the storage area of ​​the temperature control cabinet, and the air outside the condenser can be introduced into the outside of the temperature control cabinet, thereby transferring the heat outside the temperature control cabinet to the storage area of ​​the temperature control cabinet and heating the storage area of ​​the temperature control cabinet.

[0077] In one embodiment of the present application, the temperature-controlled cabinet includes a cabinet body and a cabinet door, wherein a control board and a power management module may be provided in the cabinet body, and a main board may be provided in the cabinet door.

[0078] In one embodiment of the present application, Figure 2 A schematic structural block diagram of a mainboard according to an embodiment of the present disclosure is shown. Figure 2 As shown, the mainboard 200 includes a processor 201 , a random access memory 202 , a flash memory 203 , a wireless local area network Bluetooth module 204 , a gyroscope 205 , a pressure sensor 206 , a microphone 207 , a speaker 208 , a camera 209 and a cellular communication module 210 .

[0079] A processor may include one or more processing units. For example, a processor may include one or more of an application processor, a modem processor, a graphics processor, an image signal processor, a controller, a memory, a video codec, a digital signal processor, a baseband processor, and / or a neural network processor. The different processing units may be independent devices or integrated into one or more processors.

[0080] The image signal processor is used to process data fed back by the camera. For example, when taking a photo, the shutter is opened, and light is transmitted through the lens to the camera's photosensitive element. The light signal is converted into an electrical signal, which is then passed to the image signal processor for processing and conversion into a visible image. The image signal processor can also perform algorithmic optimization on image noise, brightness, and skin color. The image signal processor can also optimize parameters such as exposure and color temperature of the captured scene. In some embodiments, the image signal processor can be located within the camera.

[0081] Digital signal processors are used to process digital signals. In addition to digital image signals, they can also process other digital signals. For example, digital signal processors can be used to perform Fourier transforms on frequency energy.

[0082] Video codecs are used to compress or decompress digital video. A temperature-controlled cabinet can support one or more video codecs. This allows the cabinet to play or record video in a variety of encoding formats, such as Moving Picture Experts Group (MPEG) 1, MPEG2, MPEG3, and MPEG4.

[0083] Neural network processors draw on the structure of biological neural networks, such as the transmission patterns between neurons in the human brain, to rapidly process input information and continuously learn. These processors can enable intelligent cognitive applications in temperature-controlled cabinets, such as image recognition, facial recognition, speech recognition, and text comprehension.

[0084] In some embodiments, the processor may include one or more interfaces. The interfaces may include an integrated circuit interface, an integrated circuit internal audio interface, a pulse code modulation interface, a universal asynchronous receiver and transmitter interface, a mobile industry processor interface, a general purpose input and output interface, a subscriber identity module interface, and / or a universal serial bus interface.

[0085] The random access memory 202 can be used to store computer executable program code, which includes instructions and data. The processor 201 executes various functional applications and data processing of the temperature control cabinet by running the instructions stored in the random access memory 202. The random access memory 202 can include a program storage area and a data storage area. The program storage area can store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc. The data storage area can store data created during the use of the temperature control cabinet (such as audio data, image data, etc.).

[0086] Flash memory 203 can be used to expand the storage capacity of the temperature control cabinet. Flash memory 203 can communicate with processor 201 through a flash memory interface to implement data storage functions. For example, files such as music and videos can be stored in the flash memory.

[0087] The processor 201 , the random access memory 202 and the flash memory 203 can form a minimum system to provide a system operating environment.

[0088] The wireless LAN Bluetooth module 204 can provide wireless communication solutions including wireless LAN, Bluetooth, global navigation satellite system, frequency modulation, short-range wireless communication technology, infrared technology, etc. applied to the temperature control cabinet.

[0101] It should be understood that the structures illustrated in the embodiments of this application do not constitute a specific limitation on the temperature-controlled cabinet. In other embodiments of this application, the temperature-controlled cabinet may include more or fewer components than shown, or may combine or separate certain components, or have different component arrangements. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

[0102] Figure 5 A schematic side cross-sectional view of a temperature control cabinet according to an embodiment of the present disclosure is shown. Figure 5 As shown, the temperature-controlled cabinet 500 includes an evaporator 501 and at least one first air outlet 502. The first air outlet 502 is disposed in a storage area 503 of the temperature-controlled cabinet 500 and is in communication with an air outlet 511 of the evaporator 501. The first air outlet 502 is configured to allow air flowing out of the air outlet 511 of the evaporator 501 to flow through the first air outlet 502 to an item entrance 513 of the storage area 503. Items can be moved into or out of the storage area 503 through the item entrance 513.

[0103] In one embodiment of the present disclosure, the temperature control cabinet may include only one first air outlet, or may include multiple first air outlets. The present disclosure does not specifically limit the number of first air outlets. When the temperature control cabinet includes multiple first air outlets, the multiple first air outlets may be connected to the air outlet of the evaporator through different air ducts, or at least two of the multiple first air outlets may share one or more air ducts and be connected to the air outlet of the evaporator through the shared air duct.

[0104] In one embodiment of the present disclosure, the first air outlet can be disposed on a side wall of the storage area or on the top of the storage area. The distance from the first air outlet to the bottom of the storage area can be greater than or equal to a first distance threshold, or the distance from the first air outlet to the bottom of the temperature-controlled cabinet can be greater than or equal to a second distance threshold.

[0105] 18. The heat dissipation controller of claim 17, wherein the heat dissipation controller is configured to control the flow of heat from the evaporator to a predetermined temperature and a predetermined range for the storage area, wherein the heat dissipation controller is configured to control the flow of heat from the evaporator to a predetermined temperature.

[0106] In one implementation of the present disclosure, Figure 6 A schematic side cross-sectional view of a temperature control cabinet according to an embodiment of the present disclosure is shown. Figure 6 As shown, the temperature control cabinet 500 further includes at least one guide device 504 disposed at the first air outlet 502 , and the guide device 504 is used to adjust the direction of air flowing out of the first air outlet 502 .

[0107] In one embodiment of the present disclosure, one guide device may be provided at each first air outlet, or multiple first guide devices may be provided. By providing multiple guide devices, the air flowing out of the first air outlet can flow in multiple directions, thereby achieving better temperature control effects for multiple items at different positions near the entrance and exit of the storage area.

[0108] In one embodiment of the present disclosure, the air guide device can adjust the direction of air flowing out of the first air outlet in response to a received control signal, or the air guide device can be manually adjusted by a corresponding operator to adjust the direction of air flowing out of the first air outlet. For example, the air guide device may include at least one air guide grille and an air guide device motor, wherein the air guide grille is rotatably connected to the first air outlet, and the rotation shaft of the air guide device motor is transmission-connected to the air guide grille via an air guide device motor transmission connecting rod. The air guide device motor can control the rotation of the transmission shaft in response to a received control command, and the transmission shaft drives the air guide grille to rotate via the air guide device motor transmission connecting rod, so that the air guide grille adjusts the direction of air flowing out of the first air outlet.

[0109] In the above technical solution, the temperature-controlled cabinet also includes at least one guide device arranged at the first air outlet, which can adjust the direction of the air flowing out of the first air outlet through the guide device, thereby achieving the purpose of accurately controlling the direction of the air flowing out of the first air outlet, so as to improve the effect of temperature control of items located at different positions near the entrance and exit of the items.

[0110] In one implementation of the present disclosure, Figure 7 A schematic side cross-sectional view of a temperature control cabinet according to an embodiment of the present disclosure is shown. Figure 7 As shown, the guide device 504 includes at least one guide plate 514 , and the guide plate 514 is rotatably connected to the first air outlet 502 .

[0111] In one embodiment of the present disclosure, the guide device may include only one guide plate or multiple guide plates. For ease of understanding, Figure 7 The guide device includes four guide plates as an example for explanation.

[0112] In one embodiment of the present disclosure, when the air guide device includes multiple air guide plates, the angles of rotation of the multiple air guide plates relative to the first air outlet may be different or the same. For example, the multiple air guide plates may be connected by a transmission connecting rod so that the multiple air guide plates are always parallel to each other, ensuring that the multiple air guide plates rotate at the same angle relative to the first air outlet.

[0113] In one embodiment of the present disclosure, a deflector in a deflector device can adjust the direction of air flowing out of the first air outlet in response to a control signal received by the deflector device, or the deflector can be manually adjusted by an operator to adjust the direction of air flowing out of the first air outlet. For example, the deflector device can include a deflector drive motor, wherein a rotation shaft of the deflector drive motor is transmission-connected to the deflector via a deflector drive motor transmission connecting rod. The deflector motor can rotate the transmission shaft in response to a received control command, and drive the deflector to rotate via the deflector drive motor transmission connecting rod, so that the deflector adjusts the direction of air flowing out of the first air outlet.

[0114] In the above technical solution, the guide device includes at least one guide plate, which is rotatably connected to the first air outlet. Compared with other guide structures such as guide tubes, the structure of the guide plate is simpler and the guide efficiency is higher. Therefore, the cost of the guide device can be relatively low, while ensuring a better effect of adjusting the direction of the air flowing out of the first air outlet.

[0115] In one implementation of the present disclosure, Figure 8 A schematic side cross-sectional view of a temperature control cabinet according to an embodiment of the present disclosure is shown. Figure 8 As shown, the guide device 504 includes at least two guide plates 514, and the at least two guide plates 514 are rotatably connected to the first air outlet 502. The at least two guide plates 514 are used to adjust the cross-sectional area of ​​the outlet 524 of the guide device 504 on the side close to the article entrance and exit 513.

[0116] In the above technical solution, by adjusting the rotation angles of at least two guide plates relative to the first air outlet, the cross-sectional area of ​​the outlet of the guide device on the side close to the item entrance and exit can be adjusted. Since air is a fluid, and for fluids, the flow rate is equal to the product of the average cross-sectional flow velocity and the cross-sectional area, when the flow rate is constant, the smaller the cross-sectional area, the greater the average cross-sectional flow velocity. By adjusting the cross-sectional area of ​​the outlet of the guide device on the side close to the item entrance and exit, the cross-sectional area of ​​the outlet of the guide device on the side close to the item entrance and exit can be made smaller than the cross-sectional area of ​​the inlet of the guide device on the side away from the item entrance and exit. In this case, the air flow velocity of the outlet of the guide device on the side close to the item entrance and exit is greater than the air flow velocity of the inlet of the guide device on the side away from the item entrance and exit. Thus, the flow velocity of the air flowing out of the first air outlet can be increased while the flow rate of the air flowing out of the first air outlet remains unchanged, thereby improving the heat exchange efficiency between the air flowing out of the first air outlet and the items in the storage area.

[0117] In one implementation of the present disclosure, Figure 9 A schematic side cross-sectional view of a temperature control cabinet according to an embodiment of the present disclosure is shown. Figure 9 As shown, the temperature control cabinet 500 also includes at least one second air outlet 505 arranged in the storage area 503, and the second air outlet 505 is connected to the air outlet 511 of the evaporator 501, so that the air flowing out from the air outlet 511 of the evaporator 501 flows to the bottom of the storage area 503 through the second air outlet 505.

[0118] In the above technical solution, the temperature-controlled cabinet also includes at least one second air outlet arranged in the storage area, and the second air outlet is connected to the air outlet of the evaporator. The air flowing out of the air outlet of the evaporator can flow to the bottom of the storage area through the second air outlet, thereby ensuring that the air flowing out of the air outlet of the evaporator can be heat-exchanged with the items in the storage area near the bottom of the storage area as soon as possible. On the premise of improving the effect of temperature control of items near the entrance and exit of items, the effect of temperature control of items in the storage area near the bottom of the storage area is avoided being affected.

[0119] In one implementation of the present disclosure, Figure 9 As shown, the temperature control cabinet 500 further includes at least one evaporation air duct 506 , and the first air outlet 502 and the second air outlet 505 are both connected to the air outlet 511 of the evaporator 501 through the corresponding evaporation air duct 506 .

[0120] In one embodiment of the present disclosure, when the temperature control cabinet includes multiple evaporation air ducts, the first air outlet and the second air outlet can both correspond to the evaporation air ducts one by one, or at least one first air outlet can also correspond to one evaporation air duct together with at least one second air outlet or at least one other first air outlet, or at least one second air outlet can also correspond to one evaporation air duct together with at least one first air outlet or at least one other second air outlet. The present disclosure does not specifically limit the correspondence between the first air outlet and the second air outlet and the evaporation air duct. For ease of understanding, Figure 9 In the description, an example is given in which the first air outlet and the second air outlet correspond to the same evaporation air duct.

[0121] In the above technical solution, the temperature control cabinet also includes at least one evaporation air duct, and the first air outlet and the second air outlet are both connected to the air outlet of the evaporator through the corresponding evaporation air duct, so that the air flowing out of the air outlet of the evaporator can flow to the first air outlet and the second air outlet through the evaporation air duct, avoiding air leakage in the process of flowing to the first air outlet or the second air outlet, thereby improving the effect of temperature control of items in the storage area.

[0122] In one implementation of the present disclosure, Figure 10 FIG2 shows a schematic side cross-sectional view of a temperature control cabinet according to an embodiment of the present disclosure. Figure 10 As shown, the temperature control cabinet 500 also includes an evaporating fan 507, the air inlet of the evaporating fan 507 is connected to the air outlet 511 of the evaporator 501, and the air outlet of the evaporating fan 507 is connected to the evaporating air duct 506. The evaporating fan 507 is used to guide air out of the air outlet 511 of the evaporator 501 and adjust the amount of air guided out of the air outlet 511 of the evaporator 501 per unit time.

[0123] In one embodiment of the present disclosure, the evaporator fan may be a fan with adjustable fan blade speed. For example, the evaporator fan may include an evaporator motor and evaporator fan blades rotatably connected to the evaporator motor. The evaporator motor may be a DC speed-controlled motor. The evaporator motor adjusts its own speed in response to a received evaporator fan speed control command. By adjusting the speed of the evaporator fan motor, the speed of the evaporator fan blades can be varied, thereby varying the suction force generated by the evaporator fan blades during rotation, and the amount of air drawn from the evaporator outlet per unit time by the rotating evaporator fan blades also varies.

[0124] In one embodiment of the present disclosure, the evaporator fan can be a fan with an adjustable fan blade inclination angle. For example, the evaporator fan may include an evaporator motor and evaporator fan blades rotatably connected to the evaporator motor. The evaporator fan can adjust the inclination angle of one or more blades of the evaporator fan blades in response to the received evaporator fan blade inclination angle control command, so that the suction force generated by the evaporator fan blades when the speed remains unchanged changes accordingly, and the amount of air drawn out from the air outlet of the evaporator by the rotated evaporator fan blades per unit time also changes accordingly.

[0125] It should be noted that in order to increase the amount of air discharged from the evaporator outlet per unit time, the evaporator fan can also be a fan with adjustable fan blade speed and adjustable fan blade inclination angle. By controlling the evaporator fan, the speed of the evaporator fan blades and the inclination angle of one or more blades in the evaporator fan blades can be adjusted at the same time.

[0126] In the above technical solution, the temperature control cabinet also includes an evaporating fan; the air inlet of the evaporating fan is connected to the air outlet of the evaporator, and the air outlet of the evaporating fan is connected to the evaporating air duct. The evaporating fan is used to guide the air out of the air outlet of the evaporator and adjust the amount of air guided out of the air outlet of the evaporator per unit time. By adjusting the amount of air guided out of the air outlet of the evaporator per unit time, the efficiency of temperature control of items in the storage area can be adjusted more conveniently.

[0127] In one implementation of the present disclosure, Figure 11 A schematic side cross-sectional view of a temperature control cabinet according to an embodiment of the present disclosure is shown. Figure 11 As shown, the temperature control cabinet 500 further includes at least one air duct control device 508, and the air duct control device 508 is connected to the side wall of the evaporation air duct.

[0128] Among them, at least one air duct control device is used to be set to a first state, a second state or a third state. The air duct control device set to the first state disconnects the first air outlet from the air outlet of the evaporator and connects the second air outlet to the air outlet of the evaporator. The air duct control device set to the second state connects the first air outlet to the air outlet of the evaporator and connects the second air outlet to the air outlet of the evaporator. The air duct control device set to the third state connects the first air outlet to the air outlet of the evaporator and disconnects the second air outlet from the air outlet of the evaporator.

[0129] In one embodiment of the present disclosure, the air duct control device can be a three-way valve, the three interfaces of which can be connected to the first air outlet, the second air outlet and the air outlet of the evaporator respectively. The three-way valve can connect or close its different interfaces in response to the control command received from the air duct control device, thereby switching between the first state, the second state and the third state. The air duct control device can also include one or more baffles rotatably connected to the air duct, and when the baffles are rotated to different postures, the corresponding positions of the air duct can be closed or connected; when the air duct control device includes multiple baffles, the multiple baffles can be in different postures. For ease of understanding, Figure 11 The description is given by taking an example in which the air duct control device includes a baffle rotatably connected to the air duct.

[0130] In the above technical solution, the temperature control cabinet also includes at least one air duct control device, which is connected to the side wall of the evaporating air duct. At least one air duct control device is used to be set to a first state, a second state or a third state, so that the conduction state between the first air outlet and the air outlet of the evaporator, and the conduction state between the second air outlet and the air outlet of the evaporator can be controlled more flexibly.

[0131] Figure 12 A flow chart of a temperature control cabinet control method according to an embodiment of the present disclosure is shown. Figure 12 As shown, the temperature control cabinet control method includes the following steps S601-S609:

[0132] In step S601, in response to the compressor of the temperature-controlled cabinet being in a shutdown state, the air duct control device of the temperature-controlled cabinet is set to a first state.

[0133] In one embodiment of the present disclosure, when the compressor of the temperature-controlled cabinet is in a shutdown state, it can be understood that the temperature control system of the temperature-controlled cabinet will not transport heat between the outside of the temperature-controlled cabinet and the storage area.

[0134] When the air duct control device of the temperature-controlled cabinet is set to the first state, the air duct control device disconnects the first air outlet from the air outlet of the evaporator and connects the second air outlet to the air outlet of the evaporator. Therefore, under the premise that the temperature control system of the temperature-controlled cabinet does not transfer heat between the outside of the temperature-controlled cabinet and the storage area, the air flowing out of the air outlet of the evaporator can only flow from the second air outlet to the bottom of the storage area. At this time, the efficiency of heat exchange between the items at the bottom of the storage area and the air in the storage area is higher.

[0135] In step S602, a first storage area temperature of a storage area of ​​a temperature-controlled cabinet collected at a first collection moment is obtained.

[0136] The difference between the first time difference and the first time difference threshold is less than or equal to the first time difference threshold, and the first time difference is the time difference between the first collection moment and the moment when the air duct control device is set to the first state.

[0137] In one embodiment of the present disclosure, the first storage area temperature can be acquired by the temperature-controlled cabinet itself or from another device or system. For example, the first storage area temperature can be acquired by a storage area temperature sensor on the temperature-controlled cabinet. The storage area temperature sensor can be located at the air inlet of the evaporator in the storage area. Air outside the evaporator (i.e., air in the storage area of ​​the temperature-controlled cabinet) can be introduced into the evaporator through the evaporator air inlet to achieve the purpose of controlling the temperature of the storage area. Alternatively, the first storage area temperature of the storage area can be acquired by an infrared thermometer and transmitted to the temperature-controlled cabinet via a wired or wireless connection.

[0138] In step S603, the air duct control device of the temperature control cabinet is set to the second state.

[0139] In one embodiment of the present disclosure, when the air duct control device of the temperature-controlled cabinet is set to the second state, the air duct control device connects the first air outlet with the air outlet of the evaporator and connects the second air outlet with the air outlet of the evaporator. Therefore, under the premise that the temperature control system of the temperature-controlled cabinet does not transfer heat between the outside of the temperature-controlled cabinet and the storage area, the air flowing out from the air outlet of the evaporator can flow from the first air outlet to the item entrance and exit, and can also flow from the second air outlet to the bottom of the storage area. At this time, the efficiency of heat exchange between the items at the bottom of the storage area and the air in the storage area is close to the efficiency of heat exchange between the items near the item entrance and exit and the air in the storage area.

[0140] In step S604, the second storage area temperature of the storage area of ​​the temperature control cabinet collected at the second collection time is obtained.

[0141] The difference between the second time difference and the second time difference threshold is less than or equal to the second time difference threshold, and the second time difference is the time difference between the second collection moment and the moment when the air duct control device is set to the second state.

[0142] In one embodiment of the present disclosure, the second storage area temperature can be acquired by the temperature-controlled cabinet itself or from another device or system. For example, the first storage area temperature can be acquired by a storage area temperature sensor on the temperature-controlled cabinet. Alternatively, the second storage area temperature can be acquired by an infrared thermometer and transmitted to the temperature-controlled cabinet via a wired or wireless connection.

[0143] In step S605, in response to the temperature difference between the first storage area temperature and the second storage area temperature being less than or equal to the first temperature difference threshold, the air duct control device of the temperature control cabinet is set to the second state, and the compressor is set to the start state.

[0144] In one embodiment of the present disclosure, when the temperature difference between the first storage area temperature and the second storage area temperature is less than or equal to the first temperature difference threshold, it can be understood that the temperature of the items located at the bottom of the storage area in the storage area is close to the temperature of the items near the item entrance and exit in the storage area, and there is no need to perform temperature control on only one of the items. Therefore, in response to the compressor of the temperature-controlled cabinet being in a shutdown state, the air duct control device of the temperature-controlled cabinet is set to the second state, and the compressor is set to the start-up state, so that the air flowing out from the air outlet of the evaporator with a certain temperature difference from the ambient temperature can flow to the bottom of the storage area and the item entrance and exit at the same time, thereby achieving the purpose of simultaneously controlling the temperature of the items located at the bottom of the storage area and the items near the item entrance and exit in the storage area.

[0145] In step S606, in response to the temperature of the first storage area being lower than the temperature of the second storage area, the temperature difference between the first storage area and the second storage area being greater than or equal to the second temperature difference threshold, and the temperature control cabinet being set to the cooling working mode, the air duct control device of the temperature control cabinet is set to the third state, and the compressor is set to the start state.

[0146] In one embodiment of the present disclosure, when the temperature of the first storage area is lower than the temperature of the second storage area, the temperature difference between the first storage area and the second storage area is greater than or equal to the second temperature difference threshold, and the temperature control cabinet is set to the cooling working mode, it can be understood that the temperature of the items near the item entrance and exit in the storage area is much higher than the temperature of the items located at the bottom of the storage area, and the temperature of the items near the item entrance and exit needs to be lowered. By setting the air duct control device of the temperature control cabinet to the third state and setting the compressor to the start state, the air flowing out of the evaporator outlet with a temperature lower than the ambient temperature can only flow to the items near the item entrance and exit in the storage area, thereby ensuring that the temperature of the items in the storage area can meet the needs of users.

[0147] In step S607, in response to the temperature of the first storage area being greater than the temperature of the second storage area, the temperature difference between the first storage area and the second storage area being greater than or equal to the third temperature difference threshold, and the temperature control cabinet being set to the cooling working mode, the air duct control device of the temperature control cabinet is set to the first state, and the compressor is set to the start state.

[0148] In one embodiment of the present disclosure, when the temperature of the first storage area is greater than the temperature of the second storage area, the temperature difference between the first storage area and the second storage area is greater than or equal to the third temperature difference threshold, and the temperature control cabinet is set to the cooling working mode, it can be understood that the temperature of the items at the bottom of the storage area in the storage area is much higher than the temperature of the items near the item entrance and exit in the storage area, and the temperature of the items at the bottom of the storage area needs to be lowered.
