A refrigeration system is also provided in the cabinet body, such as a beverage cabinet for refrigerating beverages and other items, and the storage chamber can be cooled by the refrigeration system. A heating system can also be provided in the beverage cabinet, such as a beverage cabinet for heating and storing beverages and other items, and the storage chamber can be heated by the heating system.

[0004] At present, the technologies for realizing beverage saturation detection in beverage cabinets mainly include weighing detection and camera detection. The former uses the weight detection of beverages in the beverage cabinet to infer the number of beverages in the cabinet, and compares it with the full load to obtain the beverage saturation. The beverage saturation obtained by this technical solution is relatively accurate, but the structure is complex, the cost is relatively high, and weight calibration is required, and the factory production efficiency is low. The latter uses camera photo recognition technology to compare with the photo when it is fully loaded to obtain the saturation of the beverage.

[0100] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0101] It should be noted that, although the functional modules are divided in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first", "second", etc. in the specification, claims and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0102] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0103] Beverage cabinets, also known as beverage display cabinets, are used to display beverages in shopping malls or convenience stores. With the improvement of people's living standards, the demand for various beverages is increasing. We have different temperature requirements for different beverages. In order to meet the needs of customers, various supermarkets and convenience stores have a large number of refrigerated cabinets and heating cabinets.

[0104] However, the current technologies for detecting the saturation of beverages in beverage cabinets mainly include weighing detection and camera detection. The former uses the weight detection of beverages in the beverage cabinet to infer the number of beverages in the cabinet, and compares it with the full load to obtain the beverage saturation. The beverage saturation obtained by this technical solution is relatively accurate, but the structure is complex, the cost is relatively high, and weight calibration is required, resulting in low factory production efficiency. The latter uses camera photo recognition technology to compare with the photo when it is fully loaded to obtain the saturation of the beverage. The data is accurate, but the cost is high because it requires a camera and a supporting industrial computer.

[0105] Based on this, an embodiment of the present application proposes a method for determining the beverage saturation of a beverage cabinet, which aims to determine the beverage saturation by calculating the ratio of the cooling or heating start and stop time when the beverage is fully loaded to the actual use process. While ensuring accuracy, the cost is low, and the determination method is simple and easy to implement.

[0106] The beverage cabinet of the embodiment of the present application may be a refrigeration or heating cabinet such as a cold drink cabinet, a hot drink cabinet, a cold and warm cabinet, and the technical solution for improving the beverage cabinet of the embodiment of the present application is described in detail below.

[0107] Figure 1 It is a front perspective schematic diagram of a beverage cabinet according to an embodiment of the present application.

[0108] See also Figure 1 As shown, the beverage cabinet provided in the embodiment of the present application may include a cabinet body 1. The cabinet body 1 may adopt a hollow structure such as a rectangular parallelepiped. The cabinet body 1 forms an outer shell of the beverage cabinet. It should be noted that the cabinet body 1 may also adopt a hollow shell structure of other shapes.

[0109] See also Figure 1 As shown, in some embodiments, a storage chamber 11 may be provided inside the cabinet 1, and the storage chamber 11 is used to store beverages.

[0110] See also Figure 1 As shown, in some embodiments, the storage chamber 11 can be used as an independent storage space to meet different needs such as refrigeration or heating according to different types of food, and store beverages that need to be refrigerated or heated. The storage chamber 11 can be divided into upper and lower parts, or divided into left and right parts.

[0111] See also Figure 1 As shown, in some embodiments, the beverage cabinet may include a cabinet. A storage chamber 11 may be formed in the cabinet.

[0112] See also Figure 1 As shown, in some embodiments, the beverage cabinet may include a cabinet door 12. The cabinet door 12 may be connected to the cabinet body 1 in an opening and closing manner to open and close the storage chamber 11.

[0113] It should be noted that a plurality of cabinet doors 12 may be provided, and the cabinet doors 12 may be provided in a one-to-one correspondence with the storage chambers 11 .

[0114] The cabinet door 12 may be a transparent door body. In other words, the user can see the beverage placed in the storage chamber 11 through the cabinet door 12. Thus, the user can more conveniently select the beverage he needs. In other words, the user can observe the position of the beverage in the storage chamber 11 before taking out the beverage in the storage chamber 11, so that the beverage can be quickly taken out after opening the cabinet door 12. Thus, the opening time of the cabinet door 12 can be shortened, the loss of cold or heat in the storage chamber 11 can be reduced, and the number of times the compressor of the beverage cabinet is turned on can be reduced, thereby reducing the energy consumption of the beverage cabinet.

[0115] In some embodiments, the cabinet door 12 may include a door frame and a glass panel, and the glass panel may be disposed in the door frame. In this way, not only can the beverages placed in the storage chamber 11 be seen through the glass panel, but also the appearance of the beverage cabinet can be made beautiful. Advantageously, the door frame may be a metal door frame, and a groove is provided in the door frame, and the glass panel may be disposed in the groove. Specifically, the outer edge of the glass panel may be disposed in the groove. The door frame may be provided with a door handle for the user to open and close the cabinet door 12 conveniently.

[0116] In some embodiments, the glass panel may be double-layered hollow glass, which can play a role in heat insulation and reduce the loss of cold or heat in the storage chamber 11, thereby reducing the number of times the compressor of the beverage cabinet is turned on and reducing the energy consumption of the beverage cabinet.

[0117] In some embodiments, the beverage cabinet may include a refrigeration system. The refrigeration system may be disposed inside the cabinet body 1. The refrigeration system may be used to provide cold air inside the storage chamber 11 of the beverage cabinet to maintain a low temperature environment of the storage chamber 11. The refrigeration system is a system that uses a refrigerant cycle to reduce the temperature, and may mainly include a compressor, a condenser, a throttling element, an evaporator and other main components. The refrigeration system transfers heat from a low-temperature object to a high-temperature object by circulating a refrigerant, thereby achieving a refrigeration effect.

[0118] In some embodiments, the refrigeration system may include a compressor. The compressor may serve as a power source for the refrigeration cycle, sucking in low-temperature, low-pressure refrigerant gas and compressing it into high-temperature, high-pressure gas. The compressor may deliver high-temperature, high-pressure refrigerant to the condenser.

[0119] In some embodiments, the refrigeration system may include a condenser (not shown). The condenser may be used to receive the refrigerant flowing out of the compressor, and may cool the high-temperature and high-pressure refrigerant gas from the compressor and convert it into a liquid state. The condenser may transfer the heat in the refrigerant to the surrounding air, thereby lowering the temperature of the refrigerant.

[0120] In some embodiments, the refrigeration system may include a throttling device (not shown). The condenser may deliver the condensed refrigerant to the throttling device. The throttling device may be a capillary tube. The throttling device may be used to throttle and reduce the pressure of the refrigerant.

[0121] In some embodiments, the compressor, the condenser, the throttling device, and the evaporator may be sequentially connected to form a refrigeration circuit. The refrigerant may circulate in the refrigeration circuit to achieve refrigeration of the storage chamber 11 inside the cabinet 1.

[0122] In some embodiments, the beverage cabinet may include a heating system. The heating system may be disposed inside the cabinet body 1. The heating system may be used to provide hot air inside the storage chamber 11 of the beverage cabinet to maintain a relatively high temperature environment of the storage chamber 11. The heating system is a system that utilizes a refrigerant cycle to increase the temperature, and may mainly include major components such as a compressor, a condenser, an expansion valve, an evaporator, and a heating element.

[0123] The heating system transfers heat energy by utilizing air circulation, and transfers the heat generated by the heating element to the storage chamber 11, thereby achieving the purpose of heating. Specifically, the heating system adopts the principle of refrigerant circulation heating. The refrigerant is first compressed into a high-pressure gas by an electronic membrane compressor, and then the high-temperature and high-pressure gas is cooled into a high-pressure liquid refrigerant by a condenser, and then the pressure is reduced by an expansion valve to turn the high-pressure liquid refrigerant into a low-pressure liquid refrigerant. Finally, the low-temperature and low-pressure refrigerant is turned into a low-temperature and low-pressure gaseous refrigerant by an evaporator. In this process, the heating element absorbs heat from the air, and then transfers this part of heat to the object to be heated in the storage chamber 11 through the heater.

[0124] In some embodiments, see Figure 1 The beverage cabinet further includes a temperature sensor 13 , which is disposed in the storage chamber 11 and is used to collect the temperature in the storage chamber 11 .

[0125] In some embodiments, the beverage cabinet further includes a door opening detection device, and the door opening detection device is used to detect the open / closed state of the cabinet door 12 .

[0126] In some embodiments, the beverage cabinet further includes a controller, in which a timer is provided. The temperature sensor 13 is electrically connected to the controller, so that the temperature in the storage chamber 11 obtained by the collection can be sent to the controller. Thus, when the controller detects that the temperature in the storage chamber 11 reaches the second set temperature for starting cooling or heating, the refrigeration system is controlled to start cooling or the heating system is controlled to start heating. When it is detected that the temperature in the storage chamber 11 reaches the first set temperature for stopping cooling or heating, the refrigeration system is controlled to stop cooling or the heating system is controlled to stop heating.

[0128] Reference Figure 2 , Figure 2 1 is a flow chart of a method for determining beverage saturation of a beverage cabinet provided in the first embodiment of the present application, which is executed by a controller of the beverage cabinet provided in the embodiment of the present application, including but not limited to steps S210 to S230.

[0129] Step S210, when the beverage cabinet is fully loaded with beverages, obtain a first time taken for the temperature in the storage chamber to change from a first set temperature to a second set temperature by using a timer, and obtain a second time taken for the temperature in the storage chamber to change from the second set temperature to the first set temperature by using a timer, wherein the first set temperature is a set temperature corresponding to stopping cooling or stopping heating, and the second set temperature is a set temperature corresponding to starting cooling or starting heating;

[0130] Step S220, during actual use of the beverage cabinet, obtaining a third time taken for the temperature in the storage chamber to change from the first set temperature to the second set temperature by measuring time through a timer, and obtaining a fourth time taken for the temperature in the storage chamber to change from the second set temperature to the first set temperature by measuring time through a timer;

[0131] Step S230, dividing the third time by the first time to obtain a first ratio, dividing the fourth time by the second time to obtain a second ratio, and taking the average of the first ratio and the second ratio as the saturation of the beverage in the beverage cabinet.

[0132] In the embodiment of the present application, the beverage saturation of the display-type beverage cabinet refers to the ratio of the number of beverages currently in the beverage cabinet to the full load of beverages. By monitoring the beverage saturation in the beverage cabinet, it helps customers to replenish stocks in time and improves the sales efficiency of the refrigerator.

[0133] Take the cold drink cabinet as an example. When the cold drink cabinet is working, the more beverages there are in the cold drink cabinet, the longer the refrigeration time will be to reach the first set temperature where refrigeration stops. According to the energy formula Q=CMΔT=P*t, C is the comprehensive specific heat capacity coefficient of the cold drink cabinet, that is, the comprehensive value of the specific heat capacity of the beverage and the specific heat capacity of the air in the cabinet, M is the total weight of the beverage, which is equal to the product of the weight of a single beverage m and the number of beverages n, ΔT is the refrigeration return temperature of the cold drink cabinet, which is a constant value, that is, after the temperature in the storage chamber 11 in the cold drink cabinet reaches the first set temperature Ts where refrigeration stops, the refrigeration system stops refrigeration, the temperature in the storage chamber 11 rises to the second set temperature T1, and the refrigeration system restarts refrigeration, ΔT=T1-Ts; P is the refrigeration power, and t is the time required for the temperature in the storage chamber 11 to drop from the second set temperature T1 to the first set temperature Ts after the refrigeration is restarted. Therefore, the number of beverages n=t*P / Cm(T1-Ts) can be obtained. When the cold drink cabinet is fully loaded with beverages, the time required for the temperature in the storage chamber 11 to drop from the second set temperature T1 to the first set temperature Ts after the refrigeration is restarted is measured in engineering, and the beverage saturation in the cold drink cabinet F1=n / n_max*100%=t1 / ta_max*100%. Among them, n is the number of beverages in the actual use of the cold drink cabinet, n_max is the full load of beverages, t1 is the fourth time required for the temperature in the storage chamber 11 to drop from the second set temperature T1 to the first set temperature Ts after the refrigeration is restarted during the actual use of the cold drink cabinet, and ta_max is the second time required for the temperature in the storage chamber 11 to drop from the second set temperature T1 to the first set temperature Ts after the refrigeration is restarted when the cold drink cabinet is fully loaded with beverages.

[0134] Similarly, according to the above energy formula Q=CMΔT=P*t, when the storage chamber 11 reaches the first set temperature Ts for stopping refrigeration, the refrigeration system stops refrigeration, and the time required for the cold drink cabinet to return to the second set temperature T1 from the first set temperature Ts to start refrigeration is proportional to the weight of the beverage. When the cold drink cabinet is fully loaded with beverages, the time required for the temperature in the storage chamber 11 to rise from the first set temperature Ts to the second set temperature T1 for restarting refrigeration is tb_max through engineering measurement, and the beverage saturation F2 of the cold drink cabinet can be obtained as n / n_max*100%=t2 / tb_max*100%, where n is the number of beverages in the actual use of the cold drink cabinet, n_max is the full load of beverages, t2 is the third time required for the temperature in the storage chamber 11 to return from the first set temperature Ts to the second set temperature T1 after stopping refrigeration in the actual use of the cold drink cabinet, and tb_max is the first time required for the temperature in the storage chamber 11 to return from the first set temperature Ts to the second set temperature T1 after stopping refrigeration when the cold drink cabinet is fully loaded with beverages. Then the beverage saturation F1 under the above-mentioned cooling and the beverage saturation F2 under the heating are averaged, and the beverage saturation F of the cold drink cabinet can be obtained as 1 / 2(F1+F2).

[0135] In the embodiment of the present application, the built-in timer of the controller can be used to respectively measure the first time and the third time from when the cooling or heating is stopped to when the cooling or heating is turned on again during the full load of beverages and the actual use process. At the same time, the timer can also be used to respectively measure the second time and the fourth time from when the cooling or heating is started to when the cooling or heating is stopped during the full load of beverages and the actual use process, so that the third time can be divided by the first time to obtain a first ratio, and the fourth time can be divided by the second time to obtain a second ratio, and the average of the first ratio and the second ratio is used as the saturation of the beverage in the beverage cabinet, which can ensure accuracy while being low-cost, and the determination method is simple and easy to implement.

[0136] It should be noted that for a hot drink cabinet, i.e., a drink cabinet for heating and storing drinks and other items, the storage chamber is heated by a heating system. The calculation principle and logic of the drink saturation of the hot drink cabinet are consistent with the calculation principle and logic of the drink saturation of the cold drink cabinet, and will not be elaborated here.

Therefore, the second ratio obtained by dividing the fourth time by the second time can be used as the saturation of the beverage in the beverage cabinet, which can ensure accuracy, low cost, and a simple determination method that is easy to implement.

[0224] Embodiment 3

[0225] Reference Fig.12 , Fig.12 This is a flow chart of a method for determining beverage saturation of a beverage cabinet provided in the third embodiment of the present application. The method is executed by the controller of the beverage cabinet provided in the embodiment of the present application, including but not limited to steps S1210 to S1230.

[0226] Step S1210, when the beverage cabinet is fully loaded with beverages, a first time taken for the temperature in the storage chamber to change from a first set temperature to a second set temperature is obtained by a timer, wherein the first set temperature is a set temperature corresponding to stopping cooling or stopping heating, and the second set temperature is a set temperature corresponding to starting cooling or starting heating;

[0228] Step S1230: Divide the third time by the first time to obtain a first ratio, and use the first ratio as the saturation of the beverage in the beverage cabinet.

[0229] In the embodiment of the present application, a cold drink cabinet is used as an example for explanation. The more beverages there are in the cold drink cabinet, the longer the refrigeration time is when the first set temperature at which refrigeration stops. According to the energy formula Q=CMΔT=P*t, C is the comprehensive specific heat capacity coefficient of the cold drink cabinet, which is the comprehensive value of the specific heat capacity of the beverage and the specific heat capacity of the air in the cabinet, M is the total weight of the beverage, which is equal to the product of the weight m of a single beverage and the number n of beverages, ΔT is the refrigeration return temperature of the cold drink cabinet, which is a constant value, that is, after the temperature in the storage chamber 11 in the cold drink cabinet reaches the first set temperature Ts at which refrigeration stops, the refrigeration system stops refrigeration, the temperature in the storage chamber 11 rises to the second set temperature T1, and the refrigeration system restarts refrigeration, ΔT=T1-Ts; P is the refrigeration power, and t is the time required for the temperature in the storage chamber 11 to drop from the second set temperature T1 to the first set temperature Ts after the refrigeration is restarted. Thus, the number of beverages n=t*P / Cm(T1-Ts) can be obtained. When the cold drink cabinet is fully loaded with beverages, the time required for the temperature in the storage chamber 11 to rise from the first set temperature Ts to the second set temperature T1 after the refrigeration is restarted is the first time tb_max through engineering measurement, and the beverage saturation in the cold drink cabinet F2 = n / n_max*100% = t2 / tb_max*100%.
