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] However, the temperature setting level in the current beverage cabinet is fixed, and the temperature cannot be automatically adjusted according to business hours or non-business hours, resulting in high energy consumption. Summary of the invention

[0006] To achieve the above object, an embodiment of the present application provides a control method for a beverage cabinet, the beverage cabinet comprising:

[0007] The cabinet body is used as a supporting structure of the beverage cabinet and is provided with compartments therein, wherein the compartments include a refrigeration compartment and / or a heating compartment;

[0008] A refrigeration system, which is arranged in the cabinet and is used to cool the refrigeration compartment;

[0009] and / or a heating system, which is disposed in the cabinet and is used to heat the heating compartment;

[0013] The control method comprises:

[0014] Determining whether the current time period is a business time period according to the light intensity of the environment in which the beverage cabinet is located detected by the photosensitive sensor;

[0015] When the current time period is a business time period, the refrigeration system is controlled according to the indoor temperature of the refrigeration compartment collected by the indoor temperature sensor, the set temperature of the refrigeration compartment, the ambient temperature collected by the ambient temperature sensor, and the flow of people obtained based on the detection result of the human body sensing sensor, so that the indoor temperature of the refrigeration compartment is less than or equal to the set temperature of the refrigeration compartment; and / or, when the current time period is a business time period, the heating system is controlled according to the indoor temperature of the heating compartment collected by the indoor temperature sensor, the set temperature of the heating compartment, the ambient temperature collected by the ambient temperature sensor, and the flow of people obtained based on the detection result of the human body sensing sensor, so that the indoor temperature of the heating compartment is greater than or equal to the set temperature of the heating compartment;

[0016] When the current time period is a non-business time period, the refrigeration system is controlled according to the indoor temperature of the refrigeration compartment collected by the indoor temperature sensor, the refrigeration compartment set temperature and the ambient temperature collected by the ambient temperature sensor, so that the indoor temperature of the refrigeration compartment is less than or equal to the refrigeration compartment set temperature; and / or, when the current time period is a non-business time period, the heating system is controlled according to the indoor temperature of the heating compartment collected by the indoor temperature sensor, the heating compartment set temperature and the ambient temperature collected by the ambient temperature sensor, so that the indoor temperature of the heating compartment is greater than or equal to the heating compartment set temperature.

[0017] The above technical solution has the following advantages or beneficial effects:

[0018] By arranging a photosensitive sensor, a human body induction sensor and a temperature detection device in the cabinet of the beverage cabinet, the light intensity, the ambient temperature, the indoor temperature and the flow of people in the environment of the beverage cabinet can be monitored, so that the temperature of each compartment of the beverage cabinet can be adjusted to meet the temperature requirements of the compartment while reducing energy consumption. Specifically, it can be determined whether the current time period is a business period according to the light intensity of the environment of the beverage cabinet detected by the photosensitive sensor. And when it is determined that the current time period is a business period, the cooling system and / or heating system can be controlled according to the indoor temperature of the compartment collected by the indoor temperature sensor, the set temperature of the compartment, the ambient temperature collected by the ambient temperature sensor, and the flow of people obtained by statistics based on the detection results of the human body induction sensor; when it is determined that the current time period is a non-business period, the cooling system and / or heating system can be controlled according to the indoor temperature of the compartment collected by the indoor temperature sensor, the set temperature of the compartment and the ambient temperature collected by the ambient temperature sensor. That is, the temperature of each compartment of the beverage cabinet can be adjusted according to the business hours or non-business hours to adapt to the environment and save energy, which can effectively reduce energy consumption.

[0019] In one embodiment of the present application, when the current time period is a business period, the refrigeration system is controlled according to the indoor temperature of the heating compartment collected by the indoor temperature sensor, the set temperature of the refrigeration compartment, the ambient temperature collected by the ambient temperature sensor, and the flow of people obtained based on the detection result of the human body sensing sensor, so that the indoor temperature of the refrigeration compartment is less than or equal to the set temperature of the heating compartment, including:

[0020] When the current time period is a business time period, if it is monitored that the indoor temperature of the refrigeration room collected by the indoor temperature sensor is greater than the set temperature of the refrigeration room, and the ambient temperature collected by the ambient temperature sensor is greater than or equal to the set temperature of the refrigeration room, or if it is monitored that the indoor temperature of the refrigeration room collected by the indoor temperature sensor is greater than the set temperature of the refrigeration room, but the ambient temperature collected by the ambient temperature sensor is less than the set temperature of the refrigeration room, and the human flow obtained based on the detection result of the human body sensing sensor is greater than or equal to the preset flow value, then the refrigeration system is controlled to start refrigeration until the indoor temperature of the refrigeration room is less than or equal to the set temperature of the refrigeration room;

[0021] If it is monitored that the indoor temperature of the refrigeration compartment collected by the indoor temperature sensor is less than or equal to the set temperature of the refrigeration compartment, or it is monitored that the indoor temperature of the refrigeration compartment collected by the indoor temperature sensor is greater than the set temperature of the refrigeration compartment, but the ambient temperature collected by the ambient temperature sensor is less than the set temperature of the refrigeration compartment, and the human flow rate obtained based on the detection result of the human body sensing sensor is less than the preset flow rate value, the refrigeration system is controlled not to start refrigeration.

[0022] The above technical solution has the following advantages or beneficial effects:

[0023] For automatic temperature adjustment of the refrigeration room, if the current time period is determined to be a business period by the photosensitive sensor, the indoor temperature of the refrigeration room is monitored by the indoor temperature sensor and compared with the set temperature of the refrigeration room. If the indoor temperature of the refrigeration room is less than or equal to the set temperature of the refrigeration room, the refrigeration system is controlled not to start, that is, no refrigeration is required. If the indoor temperature of the refrigeration room is greater than the set temperature of the refrigeration room, it is necessary to further determine the size of the ambient temperature and the set temperature of the refrigeration room. If the ambient temperature is also greater than or equal to the set temperature of the refrigeration room, it is necessary to control the refrigeration system to start refrigeration for the refrigeration room. If the ambient temperature is less than the set temperature of the refrigeration room, it may be possible to use the external ambient temperature to refrigerate the refrigeration room. At this time, since it is a business period, considering that there may be many customers opening the beverage cabinet to buy items in the cabinet, it will cause a lot of cold loss in the beverage cabinet. Therefore, it is necessary to further monitor the flow of people based on the human body sensing sensor. If the flow of people is greater than or equal to the preset flow value, the cold loss of the beverage cabinet is large. At this time, only using the external ambient temperature to refrigerate the refrigeration room may not meet the temperature requirements. Therefore, it is necessary to control the refrigeration system to start refrigeration to make the temperature of the refrigeration room meet the requirements. If the flow rate is less than the preset flow rate, the cold loss of the beverage cabinet is not much. At this time, only using the external ambient temperature to cool the refrigeration room can meet the temperature requirements, so the refrigeration system can be kept on. That is, when the indoor temperature of the refrigeration room is greater than the set temperature of the refrigeration room, if the ambient temperature is less than the set temperature of the refrigeration room, and the flow rate is less than the preset flow rate, the refrigeration system can be kept on, which can meet the temperature requirements and reduce energy consumption.

[0024] In one embodiment of the present application, when the current time period is a non-business time period, the refrigeration system is controlled according to the indoor temperature of the refrigeration compartment collected by the indoor temperature sensor, the refrigeration compartment set temperature, and the ambient temperature collected by the ambient temperature sensor so that the indoor temperature of the refrigeration compartment is less than or equal to the refrigeration compartment set temperature, including:

[0025] When the current time period is a non-business time period, if it is monitored that the indoor temperature of the refrigeration compartment collected by the indoor temperature sensor is greater than the set temperature of the refrigeration compartment, and the ambient temperature collected by the ambient temperature sensor is greater than or equal to the set temperature of the refrigeration compartment, the refrigeration system is controlled to start refrigeration until the indoor temperature of the refrigeration compartment is less than or equal to the set temperature of the refrigeration compartment;

[0026] If it is monitored that the indoor temperature of the refrigeration compartment collected by the indoor temperature sensor is less than or equal to the set temperature of the refrigeration compartment, or if it is monitored that the indoor temperature of the refrigeration compartment collected by the indoor temperature sensor is greater than the set temperature of the refrigeration compartment, but the ambient temperature collected by the ambient temperature sensor is less than the set temperature of the refrigeration compartment, the refrigeration system is controlled not to start refrigeration.

[0027] The above technical solution has the following advantages or beneficial effects:

[0028] For automatic temperature adjustment of the refrigeration room, if the current time period is determined to be a non-business period by the photosensitive sensor, the indoor temperature of the refrigeration room is monitored by the indoor temperature sensor and compared with the set temperature of the refrigeration room. If the indoor temperature of the refrigeration room is less than or equal to the set temperature of the refrigeration room, the refrigeration system is controlled not to start, that is, no refrigeration is required. If the indoor temperature of the refrigeration room is greater than the set temperature of the refrigeration room, it is necessary to further determine the size of the ambient temperature and the set temperature of the refrigeration room. If the ambient temperature is also greater than or equal to the set temperature of the refrigeration room, it is necessary to control the refrigeration system to start refrigeration for the refrigeration room. If the ambient temperature is less than the set temperature of the refrigeration room, it is not necessary to start the refrigeration system for refrigeration, and the external ambient temperature can be used to cool the refrigeration room, which can meet the temperature requirements of the refrigeration room. That is, when it is monitored that the indoor temperature of the refrigeration room is greater than the set temperature of the refrigeration room, if the ambient temperature is less than the set temperature of the refrigeration room, the refrigeration system can be not started for refrigeration, and the temperature requirements can be met by using the external ambient temperature, which can reduce energy consumption.

[0029] In one embodiment of the present application, when the current time period is a business time period, the heating system is controlled according to the indoor temperature of the heating compartment collected by the indoor temperature sensor, the set temperature of the heating compartment, the ambient temperature collected by the ambient temperature sensor, and the flow of people obtained based on the detection result of the human body sensing sensor, so that the indoor temperature of the heating compartment is greater than or equal to the set temperature of the heating compartment, including:

[0030] When the current time period is a business time period, if it is monitored that the indoor temperature of the heating compartment collected by the indoor temperature sensor is lower than the set temperature of the heating compartment, and the ambient temperature collected by the ambient temperature sensor is lower than or equal to the set indoor temperature; or, it is monitored that the indoor temperature of the heating compartment collected by the indoor temperature sensor is lower than the set temperature of the heating compartment, but the ambient temperature collected by the ambient temperature sensor is higher than the set temperature of the heating compartment, and the human flow rate obtained based on the detection result of the human body sensing sensor is higher than or equal to the preset flow rate value, then the heating system is controlled to start heating until the indoor temperature of the heating compartment is higher than or equal to the set temperature of the heating compartment;

[0031] If it is monitored that the indoor temperature of the heating compartment collected by the indoor temperature sensor is greater than or equal to the set temperature of the heating compartment, or it is monitored that the indoor temperature of the heating compartment collected by the indoor temperature sensor is less than the set temperature of the heating compartment, but the ambient temperature collected by the ambient temperature sensor is greater than the set temperature of the heating compartment, and the human flow rate obtained based on the detection result of the human body sensing sensor is less than the preset flow rate value, the heating system is controlled not to start heating.

[0032] The above technical solution has the following advantages or beneficial effects:

[0033] For automatic temperature adjustment of the heating room, if the current time period is determined to be business hours through the photosensitive sensor, the indoor temperature of the heating room is monitored through the indoor temperature sensor and compared with the set temperature of the heating room. If the indoor temperature of the heating room is greater than or equal to the set temperature of the heating room, the heating system is controlled not to start, that is, no heating is required. If the indoor temperature of the heating room is less than the set temperature of the heating room, it is necessary to further determine the size of the ambient temperature and the set temperature of the heating room. If the ambient temperature is also less than or equal to the set temperature of the heating room, it is necessary to control the heating system to start heating the heating room. If the ambient temperature is greater than the set temperature of the heating room, the external ambient temperature may be used to heat the heating room. At this time, since it is business hours, considering that there may be many customers opening the beverage cabinet to purchase items in the cabinet, the beverage cabinet will lose more heat. Therefore, it is necessary to further monitor the flow of people based on the human body sensing sensor. If the flow of people is greater than or equal to the preset flow value, the beverage cabinet loses more heat. At this time, only using the external ambient temperature to heat the heating room may not meet the temperature requirements. Therefore, it is necessary to control the heating system to start heating to make the temperature of the heating room meet the requirements. If the flow of people is less than the preset flow value, the heat loss of the beverage cabinet is not much. At this time, only using the external ambient temperature to heat the heating room can meet the temperature requirements, so the heating system can be started for heating. That is, when it is monitored that the indoor temperature of the heating room is less than the set temperature of the heating room, if the ambient temperature is greater than the set temperature of the heating room and the flow of people is less than the preset flow value, the heating system can be started for heating, which can meet the temperature requirements while reducing energy consumption.

[0034] In one embodiment of the present application, when the current time period is a non-business time period, the heating system is controlled according to the indoor temperature in the heating room collected by the indoor temperature sensor, the heating room set temperature, and the ambient temperature collected by the ambient temperature sensor so that the indoor temperature of the heating room is greater than or equal to the heating room set temperature, including:

[0035] When the current time period is a non-business time period, if it is monitored that the indoor temperature of the heating compartment collected by the indoor temperature sensor is lower than the set temperature of the heating compartment, and the ambient temperature collected by the ambient temperature sensor is lower than or equal to the set temperature of the heating compartment, the heating system is controlled to start heating until the indoor temperature of the corresponding compartment is higher than or equal to the set indoor temperature;

[0036] If it is monitored that the indoor temperature of the heating compartment collected by the indoor temperature sensor is greater than or equal to the set temperature of the heating compartment, or if it is monitored that the indoor temperature of the heating compartment collected by the indoor temperature sensor is less than the set temperature of the heating compartment, but the ambient temperature collected by the ambient temperature sensor is greater than the set temperature of the heating compartment, the heating system is controlled not to start heating.

[0037] The above technical solution has the following advantages or beneficial effects:

[0038] For the automatic temperature adjustment of the heating room, if the current time period is determined to be a non-business period by the photosensitive sensor, the indoor temperature of the heating room is monitored by the indoor temperature sensor and compared with the set temperature of the heating room. If the indoor temperature of the heating room is greater than or equal to the set temperature of the heating room, the heating system is controlled not to start, that is, no heating is required. If the indoor temperature of the heating room is less than the set temperature of the heating room, it is necessary to further determine the size of the ambient temperature and the set temperature of the heating room. If the ambient temperature is also less than or equal to the set temperature of the heating room, it is necessary to control the heating system to start heating the heating room. If the ambient temperature is greater than the set temperature of the heating room, there is no need to start the heating system for heating, and the external ambient temperature can be used to heat the heating room, so as to meet the temperature requirements of the heating room. That is, when it is monitored that the indoor temperature of the heating room is less than the set temperature of the heating room, if the ambient temperature is greater than the set temperature of the heating room, the heating system can be not started for heating, and the temperature requirements can be met by using the external ambient temperature, which can reduce energy consumption.

[0039] In one embodiment of the present application, after determining that the current time period is a business time period according to the light intensity of the environment in which the beverage cabinet is located detected by the photosensitive sensor, the method further includes:

[0040] Lowering the set temperature of the refrigeration compartment and reducing the temperature difference fluctuation range, and taking the sum of the adjusted set temperature of the refrigeration compartment and the temperature difference fluctuation range as the set temperature of the refrigeration compartment;

[0041] And / or, the heating compartment set temperature is increased, and the temperature difference fluctuation range is reduced, and the sum of the adjusted heating compartment set temperature and the temperature difference fluctuation range is used as the heating compartment set temperature.

[0042] The above technical solution has the following advantages or beneficial effects:

[0043] After the current time period is determined to be the business time period by the photosensitive sensor, considering that the temperature requirements for the refrigeration compartment during the business period are higher, the set temperature of the refrigeration compartment can be lowered, and the temperature difference fluctuation range can be reduced. That is, the set temperature of the refrigeration compartment is automatically adjusted to the low temperature gear, and the temperature difference fluctuation range is adjusted to a small temperature difference fluctuation range. Then the sum of the adjusted set temperature of the refrigeration compartment and the temperature difference fluctuation range is used as the set temperature of the refrigeration compartment. In this way, it can be ensured that the temperature control of the refrigeration compartment during the business period can meet the temperature requirements. Similarly, after the current time period is determined to be the business time period by the photosensitive sensor, considering that the temperature requirements for the heating compartment during the business period are higher, the set temperature of the heating compartment can be increased, and the temperature difference fluctuation range can be reduced. That is, the set temperature of the heating compartment is automatically adjusted to the high temperature gear, and the temperature difference fluctuation range is adjusted to a small temperature difference fluctuation range. Then the sum of the adjusted set temperature of the heating compartment and the temperature difference fluctuation range is used as the set temperature of the heating compartment. In this way, it can be ensured that the temperature control of the heating compartment during the business period can meet the temperature requirements.

[0044] In one embodiment of the present application, after determining that the current time period is a non-business time period according to the light intensity of the environment in which the beverage cabinet is located detected by the photosensitive sensor, the method further includes:

[0045] The set temperature of the refrigeration compartment is increased, and the temperature difference fluctuation range is increased, and the sum of the adjusted set temperature of the refrigeration compartment and the temperature difference fluctuation range is used as the set temperature of the refrigeration compartment;

[0046] And / or, the heating compartment set temperature is lowered, and the temperature difference fluctuation range is increased, and the sum of the adjusted heating compartment set temperature and the temperature difference fluctuation range is used as the heating compartment set temperature.

[0047] The above technical solution has the following advantages or beneficial effects:

[0048] After the current time period is determined to be a non-business period by the photosensitive sensor, considering that the temperature requirement for the refrigeration compartment is low during the non-business period, the set temperature of the refrigeration compartment can be increased, and the temperature difference fluctuation range can be increased. That is, the set temperature of the refrigeration compartment is automatically adjusted to the high temperature gear, and the temperature difference fluctuation range is adjusted to the large temperature difference fluctuation range. Then the sum of the adjusted set temperature of the refrigeration compartment and the temperature difference fluctuation range is used as the set temperature of the refrigeration compartment. In this way, energy consumption can be saved during non-business hours. Similarly, after the current time period is determined to be a non-business period by the photosensitive sensor, considering that the temperature requirement for the heating compartment is low during the non-business period, the set temperature of the heating compartment can be lowered, and the temperature difference fluctuation range can be increased. That is, the set temperature of the heating compartment is automatically adjusted to the low temperature gear, and the temperature difference fluctuation range is adjusted to the large temperature difference fluctuation range. Then the sum of the adjusted set temperature of the heating compartment and the temperature difference fluctuation range is used as the set temperature of the heating compartment. In this way, energy consumption can be saved during non-business hours.

[0049] In one embodiment of the present application, the beverage cabinet further includes a lighting lamp, which is disposed in the cabinet. After determining that the current time period is a business time period according to the light intensity of the environment in which the beverage cabinet is located detected by the photosensitive sensor, the method further includes:

[0050] Controlling the lighting lamp to illuminate at a first brightness;

[0051] When the human body sensing sensor detects that a person is approaching the beverage cabinet, the lighting brightness of the lighting lamp is controlled to gradually increase from the first brightness to the second brightness according to the approach distance of the person;

[0052] When the human body sensing sensor detects that a person is away from the beverage cabinet, the illumination brightness of the illumination lamp is controlled to gradually decrease from the second brightness to the first brightness according to the distance of the person away.

[0053] The above technical solution has the following advantages or beneficial effects:

[0054] After the photosensitive sensor determines that the current time period is the business period, in order to save energy, the lighting lamp can be controlled to illuminate at a lower first brightness. Only when it is detected that someone is approaching the beverage cabinet, the lighting brightness of the lighting lamp is controlled to gradually increase from the first brightness to the second brightness according to the distance of the person approaching, so as to illuminate the beverage cabinet for customers to choose. When it is detected that someone is away from the beverage cabinet, the lighting brightness of the lighting lamp is controlled to gradually decrease from the second brightness to the first brightness according to the distance of the person away, so as to achieve energy saving.

[0055] In one embodiment of the present application, the beverage cabinet further includes a lighting lamp, which is disposed in the cabinet body. After determining that the current time period is a non-business time period according to the light intensity of the environment in which the beverage cabinet is located detected by the photosensitive sensor, the method further includes:

[0056] Controlling the lighting lamp to be in an off state;

[0057] When the human body sensing sensor detects that a person is approaching the beverage cabinet, the lighting brightness of the lighting lamp is controlled to gradually increase from the off state to the second brightness according to the approach distance of the person;

[0058] When the human body sensing sensor detects that a person is away from the beverage cabinet, the lighting brightness of the lighting lamp is controlled to gradually decrease from the second brightness to the first brightness according to the distance of the person away;

[0059] When it is detected that the duration of illumination of the illuminating lamp at the first brightness is greater than or equal to the preset duration, the illuminating lamp is controlled to be turned off.

[0060] The above technical solution has the following advantages or beneficial effects:

[0061] After the photosensitive sensor determines that the current time period is a non-business period, in order to save energy, the lighting can be controlled to be off. Only when someone is detected approaching the beverage cabinet, the lighting brightness of the lighting is controlled to gradually increase from the off state to the second brightness according to the distance of the person approaching, so as to illuminate the beverage cabinet for pedestrians. When someone is detected to be away from the beverage cabinet, the lighting brightness of the lighting is controlled to gradually decrease from the second brightness to the first brightness according to the distance of the person away, and when it is detected that the duration of the lighting at the first brightness is greater than or equal to the preset duration, the lighting is controlled to be turned off, that is, the lighting is turned off after a delay of the preset time, which can achieve energy saving while also providing convenient lighting for people leaving.

[0062] In one embodiment of the present application, the method further includes:

[0063] When it is detected that the photosensor fails, the refrigeration system is controlled according to the indoor temperature of the refrigeration compartment collected by the indoor temperature sensor and the set temperature of the refrigeration compartment so that the indoor temperature of the refrigeration compartment is less than or equal to the set temperature of the refrigeration compartment; and / or the heating system is controlled according to the indoor temperature of the heating compartment collected by the indoor temperature sensor and the set temperature of the heating compartment so that the indoor temperature of the heating compartment is greater than or equal to the set temperature of the heating compartment;

[0064] The lighting lamp is controlled to be switched on and off according to the preset light-on time and light-off time.

[0065] The above technical solution has the following advantages or beneficial effects:

[0066] If a failure of the photosensitive sensor is detected, the temperature control mode of the beverage cabinet needs to be switched from the environment adaptive control mode to the compartment set temperature control mode, that is, cooling and / or heating control is performed according to the indoor temperature of the compartment and the compartment set temperature. In addition, the control mode of the lighting lamp needs to be switched from the environment adaptive control mode to the time control mode, that is, the lighting lamp is controlled according to the pre-set light on time and light off time, thereby preventing the temperature control and lighting control of the beverage cabinet from failing due to the failure of the photosensitive sensor.

[0067] To achieve the above objectives, the present application provides a beverage cabinet, comprising:

[0068] The cabinet body is used as a supporting structure of the beverage cabinet and is provided with compartments therein, wherein the compartments include a refrigeration compartment and / or a heating compartment;

[0069] A refrigeration system, which is arranged in the cabinet and is used to cool the refrigeration compartment;

[0070] and / or a heating system, which is disposed in the cabinet and is used to heat the heating compartment;

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] However, the temperature setting level in the current beverage cabinet is fixed, and the temperature cannot be automatically adjusted according to business hours or non-business hours, resulting in high energy consumption.

[0094] Based on this, the embodiment of the present application proposes a control method for a beverage cabinet, which aims to adaptively adjust the temperature of each compartment of the beverage cabinet to adapt to environmental changes and save energy according to the changes in light intensity, ambient temperature, indoor temperature and traffic flow in the monitored environment of the beverage cabinet, so as to meet the temperature requirements of the compartments while reducing energy consumption.

[0095] 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.

[0096] Figure 1 It is a front perspective schematic diagram of a beverage cabinet according to an embodiment of the present application. Figure 2 for Figure 1 A cross-sectional view of .

[0097] See also Figure 1 to Figure 2 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.

[0098] See also Figure 2 As shown, in some embodiments, a plurality of compartments may be provided inside the cabinet 1. The compartments may include a refrigeration compartment 11 and a heating compartment 12. The refrigeration compartment 11 and the heating compartment 12 may be configured as a plurality of storage compartments.

[0099] See also Figure 2 As shown, in some embodiments, the refrigeration compartment 11 and the heating compartment 12 can be used as independent storage spaces to meet different needs such as refrigeration or heating according to different types of food, and store items that need to be refrigerated or heated. The refrigeration compartment 11 and the heating compartment 12 can be arranged in a vertical separation, or in a horizontal separation. The temperature of the refrigeration compartment 11 and the heating compartment 12 can be controlled separately.

[0100] See also Figure 2 As shown, in some embodiments, the beverage cabinet may include a cabinet. A refrigeration compartment 11 and a heating compartment 12 may be formed in the cabinet.

[0101] See also Figure 2 As shown, in some embodiments, the beverage cabinet may include a door body 13. The door body 13 may be hinged to the front side of the cabinet body 1 to open and close the refrigeration compartment 11 and the heating compartment 12.

[0102] It should be noted that a plurality of door bodies 13 can be provided. The door bodies 13 can be provided one-to-one with the refrigeration compartments 11 and the heating compartments 12. One refrigeration compartment 11 can be provided with one or more door bodies 13, and one heating compartment can also be provided with one or more door bodies 13.

[0103] The door body 13 may be a transparent door body. In other words, the user can see the items placed in the refrigeration compartment 11 and the heating compartment 12 through the door body 13. Thus, the user can more conveniently select the beverages he needs. In other words, the user can observe the position of the item in the refrigeration compartment 11 or the heating compartment 12 before taking out the item, so that the item can be quickly taken out after opening the door body 13. Thus, the opening time of the door body 13 can be shortened, the loss of cold in the refrigeration compartment 11 and the loss of heat in the heating compartment 12 can be reduced, so that the number of times the compressor of the beverage cabinet is turned on can be reduced, and the energy consumption of the beverage cabinet can be reduced.

[0104] In some embodiments, the door body 13 may include a door frame and a glass panel, and the glass panel may be arranged in the door frame. In this way, not only can the items placed in the refrigeration compartment 11 or the heating compartment 12 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 arranged in the groove. Specifically, the outer edge of the glass panel may be arranged in the groove. The door frame may be provided with a door handle for users to open and close the door body 13 conveniently.

[0105] In some embodiments, the glass panel may be double-layered insulating glass, which can play a role in heat insulation, reduce the loss of cold in the refrigeration compartment 11 and the heat loss in the heating compartment 12, thereby reducing the number of times the compressor of the beverage cabinet is turned on and reducing the energy consumption of the beverage cabinet.

[0106] 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 refrigeration compartment of the beverage cabinet to maintain a low temperature environment of the refrigeration compartment 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.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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 refrigerate the refrigeration compartment 11 inside the cabinet 1.

[0111] 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 heating compartment of the beverage cabinet to maintain a relatively high temperature environment of the heating compartment 11. The heating system is a system that utilizes a refrigerant cycle to increase the temperature, and may mainly include a compressor, a condenser, an expansion valve, an evaporator, a heating element, and other major components.

[0112] The heating system transfers heat energy by air circulation, and transfers the heat generated by the heating element to the heating room 12, thereby achieving the purpose of heating. Specifically, the heating system adopts the principle of refrigerant circulation heating, firstly compresses the refrigerant into high-pressure gas through an electronic membrane compressor, then cools the high-temperature and high-pressure gas into high-pressure liquid refrigerant through a condenser, and then reduces the pressure through an expansion valve to turn the high-pressure liquid refrigerant into a low-pressure liquid refrigerant, and finally turns the low-temperature and low-pressure refrigerant into a low-temperature and low-pressure gaseous refrigerant through an evaporator. In this process, the heating element absorbs heat in the air, and then transfers this part of heat to the object to be heated in the heating room 12 through the heater.

[0113] In some embodiments, see Figure 2, the beverage cabinet further includes a photosensitive sensor 14, which is arranged on the cabinet body 1, such as being arranged on the front face or both side faces of the cabinet body 1. The photosensitive sensor 14 can also be arranged on the door body 13. The photosensitive sensor 14 is used to detect the light intensity of the environment in which the beverage cabinet is located. Specifically, when there is light during the day or the surrounding environment of the beverage cabinet is illuminated at night, it is defined as a business period; when there is no light around the beverage cabinet, it is defined as a non-business period. When the photosensitive sensor 14 detects that there is light in the environment in which the beverage cabinet is located, it can be determined that the current period is a business period. When the photosensitive sensor 14 detects that there is no light in the environment in which the beverage cabinet is located, it can be determined that the current period is a non-business period. Alternatively, when the photosensitive sensor 14 detects that the light intensity of the environment in which the beverage cabinet is located is greater than or equal to the preset light intensity, it can be determined that the current period is a business period. When the photosensitive sensor 14 detects that the light intensity of the environment in which the beverage cabinet is located is less than the preset light intensity, it can be determined that the current period is a non-business period.

[0114] In some embodiments, see Figure 2 The beverage cabinet further includes a human body sensing sensor 15, which is disposed on the cabinet body 1, such as the front end surface of the cabinet body 1. The human body sensing sensor 15 is used to detect whether a person is approaching or leaving the beverage cabinet, so that the flow of people can be statistically obtained according to the detection result of the human body sensing sensor 15, and then the cooling system and / or heating system of the beverage cabinet can be energy-saving controlled according to the flow of people.

[0115] In some embodiments, see Figure 2 The beverage cabinet further includes a temperature detection device. The temperature detection device may include an indoor temperature sensor 161 and an ambient temperature sensor 162. The indoor temperature sensor 161 may be arranged in the refrigeration compartment 11 and / or the heating compartment 12, and the indoor temperature sensor 161 is used to collect the indoor temperature of the refrigeration compartment 11 and / or the heating compartment 12. The ambient temperature sensor 162 may be arranged on the outer end surface of the cabinet 1, and the ambient temperature sensor 162 is used to collect the ambient temperature of the environment in which the cabinet 1 is located.

[0116] In one embodiment of the present application, see Figure 2 The beverage cabinet further includes a lighting lamp 17, which is arranged in the cabinet body 1 to illuminate each compartment of the beverage cabinet for displaying beverages in the cabinet. The environment of the beverage cabinet can be monitored by the photosensitive sensor 14 and the human body sensor 15, so that the brightness of the lighting lamp can be automatically adjusted according to the changes in the surrounding environment, which satisfies the original lighting needs of the user and reduces energy consumption.

[0117] Reference Figure 3 , Figure 3 1 is a flow chart of a control method of a beverage cabinet provided in an embodiment of the present application. The beverage cabinet provided in an embodiment of the present application performs the control method, including but not limited to steps S310 to S330.

[0118] Step S310, determining whether the current time period is a business period according to the light intensity of the environment in which the beverage cabinet is located detected by the photosensitive sensor;

[0119] Step S320, when the current time period is a business time period, the refrigeration system is controlled according to the indoor temperature of the refrigeration compartment collected by the indoor temperature sensor, the set temperature of the refrigeration compartment, the ambient temperature collected by the ambient temperature sensor, and the flow of people obtained by statistics based on the detection results of the human body sensing sensor, so that the indoor temperature of the refrigeration compartment is less than or equal to the set temperature of the refrigeration compartment; and / or, when the current time period is a business time period, the heating system is controlled according to the indoor temperature of the heating compartment collected by the indoor temperature sensor, the set temperature of the heating compartment, the ambient temperature collected by the ambient temperature sensor, and the flow of people obtained by statistics based on the detection results of the human body sensing sensor, so that the indoor temperature of the heating compartment is greater than or equal to the set temperature of the heating compartment;

[0120] Step S330, when the current time period is a non-business time period, the refrigeration system is controlled according to the indoor temperature of the refrigeration compartment collected by the indoor temperature sensor, the set temperature of the refrigeration compartment, and the ambient temperature collected by the ambient temperature sensor, so that the indoor temperature of the refrigeration compartment is less than or equal to the set temperature of the refrigeration compartment; and / or, when the current time period is a non-business time period, the heating system is controlled according to the indoor temperature of the heating compartment collected by the indoor temperature sensor, the set temperature of the heating compartment, and the ambient temperature collected by the ambient temperature sensor, so that the indoor temperature of the heating compartment is greater than or equal to the set temperature of the heating compartment.

[0121] In the embodiment of the present application, according to the light intensity of the environment in which the beverage cabinet is located detected by the photosensitive sensor, it can be determined whether the current time period is a business period. When it is determined that the current time period is a business period, the cooling system and / or heating system can be controlled according to the indoor temperature of the compartment collected by the indoor temperature sensor, the set temperature of the compartment, the ambient temperature collected by the ambient temperature sensor, and the flow of people obtained based on the detection results of the human body sensing sensor; when it is determined that the current time period is a non-business period, the cooling system and / or heating system can be controlled according to the indoor temperature of the compartment collected by the indoor temperature sensor, the set temperature of the compartment, and the ambient temperature collected by the ambient temperature sensor. That is, the temperature of each compartment of the beverage cabinet can be adjusted to the environment according to the business period or the non-business period, which can effectively reduce energy consumption.

[0123] Reference Figure 4 , Figure 4 4 is a flow chart of the control method of the beverage cabinet provided in the first embodiment of the present application. The beverage cabinet provided in the embodiment of the present application performs the control method, including but not limited to step S410 to step S4120.

[0124] Step S410, detecting whether there is light in the environment of the beverage cabinet by using a photosensitive sensor;

[0125] Step S420, if it is detected that there is light in the environment where the beverage cabinet is located, then determine that the current time period is a business period;

[0126] Step S430, when the current time period is a business time period, determining whether the indoor temperature of the refrigeration compartment acquired by the indoor temperature sensor is less than or equal to the set temperature of the refrigeration compartment;

[0127] Step S440, if the indoor temperature of the refrigeration compartment is greater than the set temperature of the refrigeration compartment, then determining whether the ambient temperature collected by the ambient temperature sensor is less than the set temperature of the refrigeration compartment;

[0128] Step S450, if the ambient temperature is lower than the set temperature of the refrigeration compartment, determining whether the human flow rate obtained based on the detection result of the human body sensing sensor is greater than or equal to a preset flow rate value;

[0129] Step S460: If the flow rate of people is greater than or equal to the preset flow rate value, or the ambient temperature is greater than or equal to the set temperature of the refrigeration room, the refrigeration system is controlled to start refrigeration until the indoor temperature of the refrigeration room is less than or equal to the set temperature of the refrigeration room;

[0130] Step S470: If the flow rate of people is less than the preset flow rate value, or the indoor temperature of the refrigeration room is less than or equal to the set temperature of the refrigeration room, the refrigeration system is controlled not to start refrigeration;

[0131] Step S480, if it is detected that there is no light in the environment of the beverage cabinet, then the current time period is determined to be a non-business time period;

[0132] Step S490, when the current time period is a non-business time period, determining whether the indoor temperature of the refrigeration compartment acquired by the indoor temperature sensor is less than or equal to the set temperature of the refrigeration compartment;

[0133] Step S4100, if the indoor temperature of the refrigeration compartment is greater than the set temperature of the refrigeration compartment, determine whether the ambient temperature collected by the ambient temperature sensor is less than the set temperature of the refrigeration compartment;

[0134] Step S4110, if the ambient temperature is greater than or equal to the set temperature of the refrigeration compartment, the refrigeration system is controlled to start refrigeration until the indoor temperature of the refrigeration compartment is less than or equal to the set temperature of the refrigeration compartment;

[0135] Step S4120: If the ambient temperature is lower than the set temperature of the refrigeration compartment, or the indoor temperature of the refrigeration compartment is lower than or equal to the set temperature of the refrigeration compartment, the refrigeration system is controlled not to start refrigeration.

[0136] In the embodiment of the present application, for the automatic temperature adjustment of the refrigeration compartment, if the current time period is determined to be a business period by a photosensitive sensor, the indoor temperature of the refrigeration compartment is monitored by an indoor temperature sensor, and compared with the set temperature of the refrigeration compartment. If the indoor temperature of the refrigeration compartment is less than or equal to the set temperature of the refrigeration compartment, the refrigeration system is controlled not to start, that is, no refrigeration is required. If the indoor temperature of the refrigeration compartment is greater than the set temperature of the refrigeration compartment, it is necessary to further determine the size of the ambient temperature and the set temperature of the refrigeration compartment. If the ambient temperature is also greater than or equal to the set temperature of the refrigeration compartment, it is necessary to control the refrigeration system to start refrigeration for the refrigeration compartment. Specifically, the compressor and the fan can be controlled to gradually increase the power by 50%, 80%, and 100% according to the downward trend of the indoor temperature of the compartment to achieve refrigeration. If the ambient temperature is lower than the set temperature of the refrigeration room, the external ambient temperature may be used to cool the refrigeration room. At this time, since it is business hours, considering that there may be many customers opening the beverage cabinet to buy items in the cabinet, the cold loss of the beverage cabinet will be large. Therefore, it is necessary to further monitor the flow of people based on the human body sensing sensor. If the flow of people is greater than or equal to the preset flow value, the cold loss of the beverage cabinet is large. At this time, only using the external ambient temperature to cool the refrigeration room may not meet the temperature requirements. Therefore, it is necessary to control the refrigeration system to start refrigeration to make the temperature of the refrigeration room meet the requirements. Specifically, the compressor and the fan can be controlled to run at 100% power and high speed to achieve rapid refrigeration. If the flow of people is less than the preset flow value, the cold loss of the beverage cabinet is not much. At this time, only using the external ambient temperature to cool the refrigeration room can meet the temperature requirements, so the refrigeration system can be started for refrigeration. That is, when it is monitored that the indoor temperature of the refrigeration room is greater than the set temperature of the refrigeration room, if the ambient temperature is less than the set temperature of the refrigeration room, and the flow of people is less than the preset flow value, the refrigeration system can be started for refrigeration, which can meet the temperature requirements while reducing energy consumption.

[0137] If the current time period is determined to be a non-business period by the photosensitive sensor, the indoor temperature of the refrigeration room is monitored by the indoor temperature sensor and compared with the set temperature of the refrigeration room. If the indoor temperature of the refrigeration room is less than or equal to the set temperature of the refrigeration room, the refrigeration system is controlled not to start, that is, no refrigeration is required. If the indoor temperature of the refrigeration room is greater than the set temperature of the refrigeration room, it is necessary to further determine the size of the ambient temperature and the set temperature of the refrigeration room. If the ambient temperature is also greater than or equal to the set temperature of the refrigeration room, it is necessary to control the refrigeration system to start refrigeration for the refrigeration room. Specifically, the compressor and the fan can be controlled to run at 50% power to achieve refrigeration. If the ambient temperature is less than the set temperature of the refrigeration room, there is no need to start the refrigeration system for refrigeration. The external ambient temperature can be used to cool the refrigeration room, which can meet the temperature requirements of the refrigeration room. That is, when it is monitored that the indoor temperature of the refrigeration room is greater than the set temperature of the refrigeration room, if the ambient temperature is less than the set temperature of the refrigeration room, the refrigeration system can be not started for refrigeration. The temperature requirements can be met by using the external ambient temperature, which can reduce energy consumption.

[0139] Reference Figure 5 , Figure 5 1 is a flow chart of a control method of a beverage cabinet provided in the second embodiment of the present application. The beverage cabinet provided in the embodiment of the present application performs the control method, including but not limited to steps S510 to S5140.

[0140] Step S510, detecting whether there is light in the environment of the beverage cabinet by using a photosensitive sensor;

[0141] Step S520, if it is detected that there is light in the environment where the beverage cabinet is located, then determine that the current time period is a business period;

[0142] Step S530, when the current period is a business period, the set temperature of the refrigeration compartment is lowered, and the temperature difference fluctuation range is reduced, and the sum of the adjusted set temperature of the refrigeration compartment and the temperature difference fluctuation range is used as the set temperature of the refrigeration compartment;

[0143] Step S540, determining whether the indoor temperature of the refrigeration compartment acquired by the indoor temperature sensor is less than or equal to the set temperature of the refrigeration compartment;

[0144] Step S550, if the indoor temperature of the refrigeration compartment is greater than the set temperature of the refrigeration compartment, then determine whether the ambient temperature collected by the ambient temperature sensor is less than the set temperature of the refrigeration compartment;

[0145] Step S560, if the ambient temperature is lower than the set temperature of the refrigeration compartment, determining whether the human flow rate obtained based on the detection result of the human body sensing sensor is greater than or equal to a preset flow rate value;

[0146] Step S570: If the flow rate of people is greater than or equal to the preset flow rate value, or the ambient temperature is greater than or equal to the set temperature of the refrigeration room, the refrigeration system is controlled to start refrigeration until the indoor temperature of the refrigeration room is less than or equal to the set temperature of the refrigeration room;

[0147] Step S580: If the flow rate of people is less than the preset flow rate value, or the indoor temperature of the refrigeration room is less than or equal to the set temperature of the refrigeration room, the refrigeration system is controlled not to start refrigeration;

[0148] Step S590, if it is detected that there is no light in the environment of the beverage cabinet, then the current time period is determined to be a non-business time period;

[0149] Step S5100, when the current time period is a non-business time period, the set temperature of the refrigeration compartment is increased, and the temperature difference fluctuation range is increased, and the sum of the adjusted set temperature of the refrigeration compartment and the temperature difference fluctuation range is used as the set temperature of the refrigeration compartment;

[0150] Step S5110, determining whether the indoor temperature of the refrigeration compartment acquired by the indoor temperature sensor is less than or equal to the set temperature of the refrigeration compartment;

[0151] Step S5120, if the indoor temperature of the refrigeration compartment is greater than the set temperature of the refrigeration compartment, determine whether the ambient temperature collected by the ambient temperature sensor is less than the set temperature of the refrigeration compartment;

[0152] Step S5130, if the ambient temperature is greater than or equal to the set temperature of the refrigeration compartment, the refrigeration system is controlled to start refrigeration until the indoor temperature of the refrigeration compartment is less than or equal to the set temperature of the refrigeration compartment;

[0153] Step S5140: If the ambient temperature is lower than the set temperature of the refrigeration compartment, or the indoor temperature of the refrigeration compartment is lower than or equal to the set temperature of the refrigeration compartment, the refrigeration system is controlled not to start refrigeration.

[0154] In the embodiment of the present application, for the automatic temperature adjustment of the refrigeration compartment, if the current period is determined to be a business period by the photosensitive sensor, considering that the business period has a higher temperature requirement for the refrigeration compartment, the set temperature of the refrigeration compartment can be lowered and the temperature difference fluctuation range can be reduced. That is, the set temperature of the refrigeration compartment is automatically adjusted to a low temperature gear, and the temperature difference fluctuation range is adjusted to a small temperature difference fluctuation range. Then the sum of the adjusted set temperature of the refrigeration compartment and the temperature difference fluctuation range is used as the set temperature of the refrigeration compartment. In this way, it can be ensured that the temperature control of the refrigeration compartment during the business period can meet the temperature requirements. Then the indoor temperature of the refrigeration compartment is monitored by the indoor temperature sensor, and compared with the size of the set temperature of the refrigeration compartment. If the indoor temperature of the refrigeration compartment is less than or equal to the set temperature of the refrigeration compartment, the refrigeration system is controlled not to start, that is, no refrigeration is required. If the indoor temperature of the refrigeration compartment is greater than the set temperature of the refrigeration compartment, it is necessary to further judge the size of the ambient temperature and the set temperature of the refrigeration compartment. If the ambient temperature is also greater than or equal to the set temperature of the refrigeration compartment, it is necessary to control the refrigeration system to start refrigeration for the refrigeration compartment. Specifically, the compressor and the fan can be controlled to gradually increase the power by 50%, 80%, and 100% according to the downward trend of the indoor temperature of the compartment to achieve refrigeration. If the ambient temperature is lower than the set temperature of the refrigeration compartment, the external ambient temperature may be used to refrigerate the refrigeration compartment. At this time, since it is business hours, considering that there may be many customers opening the beverage cabinet to purchase items in the cabinet, the cold amount of the beverage cabinet will be lost more. Therefore, it is necessary to further monitor the flow of people based on the human body sensing sensor. If the flow of people is greater than or equal to the preset flow value, the cold amount of the beverage cabinet is lost more. At this time, only using the external ambient temperature to refrigerate the refrigeration compartment may not meet the temperature requirements. Therefore, it is necessary to control the refrigeration system to start refrigeration to make the temperature of the refrigeration compartment meet the requirements. Specifically, the compressor and the fan can be controlled to run at 100% power and high speed to achieve rapid refrigeration. If the flow of people is less than the preset flow value, the cold amount of the beverage cabinet is not lost much. At this time, only using the external ambient temperature to refrigerate the refrigeration compartment can meet the temperature requirements, so the refrigeration system can be started for refrigeration. That is, when it is detected that the indoor temperature of the refrigeration room is greater than the set temperature of the refrigeration room, if the ambient temperature is less than the set temperature of the refrigeration room and the flow of people is less than the preset flow value, the refrigeration system may not be started for refrigeration, which can meet the temperature requirements and reduce energy consumption. If the current period is determined to be a non-business period by the photosensitive sensor, considering that the temperature requirements for the refrigeration room are lower during non-business periods, the set temperature of the refrigeration room can be increased and the temperature difference fluctuation range can be increased. That is, the set temperature of the refrigeration room is automatically adjusted to the high temperature gear, and the temperature difference fluctuation range is adjusted to a large temperature difference fluctuation range. Then the sum of the adjusted set temperature of the refrigeration room and the temperature difference fluctuation range is used as the set temperature of the refrigeration room. In this way, energy consumption can be saved during non-business hours. Then the indoor temperature of the refrigeration room is monitored by the indoor temperature sensor, and compared with the set temperature of the refrigeration room.If the indoor temperature of the refrigeration room is less than or equal to the set temperature of the refrigeration room, the refrigeration system is controlled not to start, that is, no refrigeration is required. If the indoor temperature of the refrigeration room is greater than the set temperature of the refrigeration room, it is necessary to further determine the size of the ambient temperature and the set temperature of the refrigeration room. If the ambient temperature is also greater than or equal to the set temperature of the refrigeration room, it is necessary to control the refrigeration system to start refrigeration for the refrigeration room.

If the ambient temperature is less than the set temperature of the refrigeration room, there is no need to start the refrigeration system for refrigeration. The external ambient temperature can be used to cool the refrigeration room to meet the temperature requirements of the refrigeration room. That is, when it is monitored that the indoor temperature of the refrigeration room is greater than the set temperature of the refrigeration room, if the ambient temperature is less than the set temperature of the refrigeration room, the refrigeration system can be not started for refrigeration. The temperature requirements can be met by using the external ambient temperature, which can reduce energy consumption.

At this time, since it is business hours, considering that there may be many customers opening the beverage cabinet to purchase items in the cabinet, the beverage cabinet will lose more heat. Therefore, it is necessary to further monitor the flow of people based on the human body sensing sensor. If the flow of people is greater than or equal to the preset flow value, the beverage cabinet loses more heat. At this time, only using the external ambient temperature to heat the heating room may not meet the temperature requirements. Therefore, it is necessary to control the heating system to start heating to make the temperature of the heating room meet the requirements. Specifically, the compressor and heating elements can be controlled to run at 100% power and high speed to achieve rapid heating. If the flow of people is less than the preset flow value, the heat loss of the beverage cabinet is not much. At this time, only using the external ambient temperature to heat the heating room can meet the temperature requirements, so the heating system can be started for heating. That is, when it is monitored that the indoor temperature of the heating room is lower than the set temperature of the heating room, if the ambient temperature is higher than the set temperature of the heating room, and the flow of people is lower than the preset flow value, the heating system may not be started for heating, which can meet the temperature requirements while reducing energy consumption.

[0170] If the current time period is determined to be a non-business period through the photosensitive sensor, the indoor temperature of the heating room is monitored through the indoor temperature sensor and compared with the set temperature of the heating room. If the indoor temperature of the heating room is greater than or equal to the set temperature of the heating room, the heating system is controlled not to start, that is, no heating is required. If the indoor temperature of the heating room is less than the set temperature of the heating room, it is necessary to further determine the size of the ambient temperature and the set temperature of the heating room. If the ambient temperature is also less than or equal to the set temperature of the heating room, it is necessary to control the heating system to start heating the heating room. Specifically, the compressor and the heating element can be controlled to operate at 50% power to achieve heating. If the ambient temperature is greater than the set temperature of the heating room, there is no need to start the heating system for heating. The external ambient temperature can be used to heat the heating room to meet the temperature requirements of the heating room. That is, when it is monitored that the indoor temperature of the heating room is lower than the set temperature of the heating room, if the ambient temperature is higher than the set temperature of the heating room, the heating system may not be started for heating, and the temperature requirement may be met by using the external ambient temperature, thereby reducing energy consumption.

The beverage cabinet provided in the embodiment of the present application performs the control method, including but not limited to steps S710 to S7140.

[0173] Step S710, detecting whether there is light in the environment of the beverage cabinet by using a photosensitive sensor;

[0174] Step S720, if it is detected that there is light in the environment where the beverage cabinet is located, then determine that the current time period is a business period;

[0175] Step S730, when the current period is a business period, the heating room set temperature is increased, and the temperature difference fluctuation range is reduced, and the sum of the adjusted heating room set temperature and the temperature difference fluctuation range is used as the heating room set temperature;

[0176] Step S740, determining whether the indoor temperature of the heating room acquired by the indoor temperature sensor is lower than the set temperature of the heating room;

[0177] Step S750, if the indoor temperature of the heating room is lower than the set temperature of the heating room, it is determined whether the ambient temperature collected by the ambient temperature sensor is lower than or equal to the set temperature of the heating room;

[0178] Step S760: if the ambient temperature is greater than the set temperature of the heating room, determine whether the human flow rate obtained based on the detection result of the human body sensing sensor is greater than or equal to a preset flow rate value;

[0179] Step S770: If the flow of people is greater than or equal to the preset flow value, or the ambient temperature is less than or equal to the set temperature of the heating room, the heating system is controlled to start heating until the indoor temperature of the heating room is greater than or equal to the set temperature of the heating room;

[0180] Step S780: If the flow rate of people is less than the preset flow rate value, or the indoor temperature of the heating room is greater than or equal to the set temperature of the heating room, the heating system is controlled not to start heating;

[0181] Step S790, if it is detected that there is no light in the environment of the beverage cabinet, then the current time period is determined to be a non-business time period;

[0182] Step S7100, when the current time period is a non-business time period, the set temperature of the heating room is lowered, and the temperature difference fluctuation range is increased, and the sum of the adjusted set temperature of the heating room and the temperature difference fluctuation range is used as the set temperature of the heating room;

[0183] Step S7110, determining whether the indoor temperature of the heating room acquired by the indoor temperature sensor is lower than the set temperature of the heating room;

[0184] Step S7120: if the indoor temperature of the heating room is lower than the set temperature of the heating room, determine whether the ambient temperature collected by the ambient temperature sensor is lower than or equal to the set temperature of the heating room;

[0185] Step S7130: if the ambient temperature is less than or equal to the set temperature of the heating room, the heating system is controlled to start heating until the indoor temperature of the heating room is greater than or equal to the set temperature of the heating room;

[0186] Step S7140: If the ambient temperature is greater than the set temperature of the heating compartment, or the indoor temperature of the heating compartment is greater than or equal to the set temperature of the heating compartment, the heating system is controlled not to start heating.

[0187] In the embodiment of the present application, for the automatic temperature adjustment of the heating room, if the current time period is determined to be the business time period by the photosensitive sensor, considering that the temperature requirement of the heating room is higher during the business time period, the set temperature of the heating room can be increased and the temperature difference fluctuation range can be reduced. That is, the set temperature of the heating room is automatically adjusted to the high temperature gear, and the temperature difference fluctuation range is adjusted to the small temperature difference fluctuation range. Then the sum of the adjusted set temperature of the heating room and the temperature difference fluctuation range is used as the set temperature of the heating room. In this way, it can be ensured that the temperature control of the heating room during the business period can meet the temperature requirement. Then the indoor temperature of the heating room is monitored by the indoor temperature sensor, and compared with the set temperature of the heating room. If the indoor temperature of the heating room is greater than or equal to the set temperature of the heating room, the heating system is controlled not to start, that is, heating is not required. If the indoor temperature of the heating room is less than the set temperature of the heating room, it is necessary to further judge the size of the ambient temperature and the set temperature of the heating room. If the ambient temperature is also less than or equal to the set temperature of the heating room, it is necessary to control the heating system to start heating the heating room. Specifically, the compressor and heating element can be controlled to gradually increase the power by 50%, 80%, and 100% according to the rising trend of the indoor temperature of the compartment to achieve heating. If the ambient temperature is greater than the set temperature of the heating compartment, the external ambient temperature may be used to heat the heating compartment. At this time, since it is business hours, considering that there may be many customers opening the beverage cabinet to purchase items in the cabinet, the beverage cabinet will lose more heat. Therefore, it is necessary to further monitor the flow of people based on the human body sensing sensor. If the flow of people is greater than or equal to the preset flow value, the beverage cabinet loses more heat. At this time, only using the external ambient temperature to heat the heating compartment may not meet the temperature requirements. Therefore, it is necessary to control the heating system to start heating to make the temperature of the heating compartment meet the requirements. Specifically, the compressor and heating element can be controlled to run at 100% power and high speed to achieve rapid heating. If the flow of people is less than the preset flow value, the heat loss of the beverage cabinet is not much. At this time, only using the external ambient temperature to heat the heating compartment can meet the temperature requirements, so the heating system can be started for heating. That is, when it is monitored that the indoor temperature of the heating room is lower than the set temperature of the heating room, if the ambient temperature is higher than the set temperature of the heating room, and the flow of people is lower than the preset flow value, the heating system may not be started for heating, which can meet the temperature requirements while reducing energy consumption.

[0188] If the current time period is determined to be a non-business period by the photosensitive sensor, considering that the temperature requirement for the heating room is lower during the non-business period, the set temperature of the heating room can be lowered and the temperature difference fluctuation range can be increased. That is, the set temperature of the heating room is automatically adjusted to the low temperature gear, and the temperature difference fluctuation range is adjusted to the large temperature difference fluctuation range. Then the sum of the adjusted set temperature of the heating room and the temperature difference fluctuation range is used as the set temperature of the heating room. In this way, energy consumption can be saved during non-business hours. Then the indoor temperature of the heating room is monitored by the indoor temperature sensor, and compared with the set temperature of the heating room. If the indoor temperature of the heating room is greater than or equal to the set temperature of the heating room, the heating system is controlled not to start, that is, heating is not required. If the indoor temperature of the heating room is less than the set temperature of the heating room, it is necessary to further judge the size of the ambient temperature and the set temperature of the heating room. If the ambient temperature is also less than or equal to the set temperature of the heating room, it is necessary to control the heating system to start heating the heating room. Specifically, the compressor and the heating element can be controlled to operate at 50% power to achieve heating. If the ambient temperature is higher than the set temperature of the heating room, the heating system does not need to be started for heating. The external ambient temperature can be used to heat the heating room to meet the temperature requirements of the heating room. That is, when the indoor temperature of the heating room is lower than the set temperature of the heating room, if the ambient temperature is higher than the set temperature of the heating room, the heating system does not need to be started for heating. The temperature requirements can be met by using the external ambient temperature, which can reduce energy consumption.

[0189] Embodiment 5

[0190] Reference Figure 8 , Figure 8 1 is a flow chart of a control method of a beverage cabinet provided in Embodiment 5 of the present application. The beverage cabinet provided in the embodiment of the present application performs the control method, including but not limited to steps S810 to S8140.

[0191] Step S810, detecting whether there is light in the environment of the beverage cabinet by using a photosensitive sensor;

[0192] Step S820, if it is detected that there is light in the environment where the beverage cabinet is located, then determine that the current time period is a business period;

[0193] Step S830, when the current time period is a business time period, controlling the lighting lamp to illuminate at a first brightness;

[0194] Step S840, detecting whether a person is approaching the beverage cabinet by a human body sensing sensor;

[0195] Step S850, if it is detected that someone is approaching the beverage cabinet, the lighting brightness of the lighting lamp is controlled to gradually increase from the first brightness to the second brightness according to the approach distance of the person;

[0196] Step S860, detecting whether a person is away from the beverage cabinet by a human body sensing sensor;

[0197] Step S870, if it is detected that a person is away from the beverage cabinet, the lighting brightness of the lighting lamp is controlled to gradually decrease from the second brightness to the first brightness according to the distance of the person away;

[0198] Step S880, if it is detected that there is no light in the environment of the beverage cabinet, then the current time period is determined to be a non-business time period;

[0199] Step S890, when the current time period is a non-business time period, the lighting is controlled to be turned off;

[0200] Step S8100, detecting whether a person is approaching the beverage cabinet by a human body sensing sensor;

[0201] Step S8110, if it is detected that someone is approaching the beverage cabinet, the lighting brightness of the lighting lamp is controlled to gradually increase from the off state to the second brightness according to the approach distance of the person;

[0202] Step S8120, detecting whether a person is away from the beverage cabinet by a human body sensing sensor;

[0203] Step S8130, if it is detected that a person is away from the beverage cabinet, the lighting brightness of the lighting lamp is controlled to gradually decrease from the second brightness to the first brightness according to the distance of the person away;

[0204] Step S8140, detecting whether the duration of the lighting lamp lighting at the first brightness is greater than or equal to the preset duration; if the duration of the lighting lamp lighting at the first brightness is greater than or equal to the preset duration, returning to step S890.

[0205] In the embodiment of the present application, after the current time period is determined to be a business period by the photosensitive sensor, in order to save energy, the lighting lamp can be controlled to illuminate at a lower first brightness. Only when it is detected that someone is approaching the beverage cabinet, the lighting brightness of the lighting lamp is controlled to gradually increase from the first brightness to the second brightness according to the distance of the person approaching, so as to illuminate the beverage cabinet for customers to choose. When it is detected that someone is away from the beverage cabinet, the lighting brightness of the lighting lamp is controlled to gradually decrease from the second brightness to the first brightness according to the distance of the person away, so as to achieve energy saving. Specifically, after the current time period is determined to be a business period by the photosensitive sensor, the lighting lamp can be controlled to run at 30% power through PWM adjustment to achieve energy saving. When the human body sensing sensor detects that someone is approaching the beverage cabinet, the lighting lamp is controlled to gradually light up the lighting lamp according to the distance of the person approaching, through PWM adjustment, according to 30%, 50%, 80%, 100% of the light power, so as to facilitate people to select drinks. When the human body sensing sensor detects that a person has left the beverage cabinet, the brightness of the light is gradually reduced through PWM adjustment according to 100%, 80%, 50%, and 30% of the light power. Finally, the light is controlled to maintain 30% low power operation to facilitate the display of beverages in the cabinet during business hours.

[0206] After the current time period is determined to be a non-business time period by the photosensitive sensor, in order to save energy, the lighting lamp can be controlled to be in the off state. Only when it is detected that someone is approaching the beverage cabinet, the lighting brightness of the lighting lamp is controlled to gradually increase from the off state to the second brightness according to the distance of the person approaching, so as to illuminate the beverage cabinet for pedestrians. When it is detected that someone is away from the beverage cabinet, the lighting brightness of the lighting lamp is controlled to gradually decrease from the second brightness to the first brightness according to the distance of the person away, and when it is detected that the duration of the lighting lamp lighting at the first brightness is greater than or equal to the preset duration, the lighting lamp is controlled to be turned off, that is, the lighting lamp is turned off after a delay of the preset time, which can achieve energy saving while also facilitating lighting for the person leaving. Specifically, after the current time period is determined to be a non-business time period by the photosensitive sensor, the flow of people is low at this time, and the lighting lamp is controlled to be turned off. If the human body sensing sensor detects that someone is approaching the beverage cabinet, the lighting lamp is controlled to be gradually lit according to the distance of the person approaching, through PWM adjustment, according to 30%, 50%, 80%, 100% of the power of the bright lamp, which is energy-saving and convenient for people who take drinks at night. When the human body sensing sensor detects that a person has left, the brightness of the light is gradually reduced by 100%, 80%, 50%, and 30% through PWM adjustment. When the light power drops to 30%, it is turned off after a preset delay to provide lighting for the person who has left.
