Description

Technical Field

[0001] This application relates to the field of electrical technology, and in particular to a beverage cabinet and its control method. Background Technology

[0002] Commercial display cabinets such as beverage cabinets on the market generally have multiple shelves inside for placing goods.

[0003] In related technologies, beverage cabinets typically include a cabinet body defining a storage chamber with a front opening; and a door connected to the cabinet body for opening and closing the storage chamber. The cabinet also includes a refrigeration system; for example, in a beverage cabinet used for refrigerating beverages, the refrigeration system cools the storage chamber. Alternatively, a heating system may be included; for example, in a beverage cabinet used for heating and storing beverages, the heating system heats the storage chamber.

[0004] However, the temperature settings in beverage cabinets are currently fixed and cannot be automatically adjusted according to business hours or non-business hours, resulting in high energy consumption. Summary of the Invention

[0005] The main objective of this application is to propose a beverage cabinet and its control method, which aims to make adaptive energy-saving adjustments to the temperature of each compartment of the beverage cabinet based on the monitored changes in light intensity, ambient temperature, room temperature, and traffic flow, thereby meeting the room temperature requirements while reducing energy consumption.

[0006] To achieve the above objectives, this application proposes a control method for a beverage cabinet, the beverage cabinet comprising:

[0007] The cabinet, which serves as the supporting structure for the beverage cabinet, has internal compartments, including a refrigeration compartment and / or a heating compartment.

[0008] A refrigeration system, located inside the cabinet, is used to cool and reduce the temperature of the refrigeration room;

[0009] and / or a heating system, which is located inside the cabinet, for heating the heating room;

[0010] A photosensitive sensor, which is installed in the cabinet, is used to detect the light intensity of the environment in which the beverage cabinet is located;

[0011] A human body sensor is installed in the cabinet to detect whether someone is approaching or moving away from the beverage cabinet;

[0012] A temperature detection device includes an indoor temperature sensor and an ambient temperature sensor. The indoor temperature sensor is installed in the cooling room and / or the heating room to collect the indoor temperature of the cooling room and / or the heating room. The ambient temperature sensor is installed on the outer end face of the cabinet to collect the ambient temperature of the environment in which the cabinet is located.

[0013] The control method includes:

[0014] Based on the light intensity of the environment where the beverage cabinet is located, as detected by the photosensitive sensor, it is determined whether the current time period is a business period;

[0015] When the current period is a business day, the cooling system is controlled based on the indoor temperature of the refrigerated room collected by the indoor temperature sensor, the set temperature of the refrigerated room, the ambient temperature collected by the ambient temperature sensor, and the flow of people statistically obtained based on the detection results of the human body sensor, so that the indoor temperature of the refrigerated room is less than or equal to the set temperature of the refrigerated room; and / or, when the current period is a business day, the heating system is controlled based on the indoor temperature of the heating room collected by the indoor temperature sensor, the set temperature of the heating room, the ambient temperature collected by the ambient temperature sensor, and the flow of people statistically obtained based on the detection results of the human body sensor, so that the indoor temperature of the heating room is greater than or equal to the set temperature of the heating room.

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

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

[0018] By installing photosensitive sensors, human body sensors, and temperature detection devices in the beverage cabinet, the ambient light intensity, ambient temperature, compartment temperature, and pedestrian traffic changes in the environment surrounding the beverage cabinet can be monitored. Based on the monitoring results, the temperature of each compartment of the beverage cabinet can be adaptively adjusted to meet environmental changes and reduce energy consumption. Specifically, the light intensity detected by the photosensitive sensor can determine whether the current time period is a business day. If it is a business day, the cooling and / or heating systems can be controlled based on 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 pedestrian traffic statistics based on the detection results of the human body sensor. If it is a non-business day, the cooling and / or heating systems can be controlled based on 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. This means that the temperature of each compartment of the beverage cabinet can be adaptively adjusted according to business hours or non-business hours to save energy, which can effectively reduce energy consumption.

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

[0020] When the current period is during business hours, if the indoor temperature of the refrigerated room detected by the indoor temperature sensor is greater than the set temperature of the refrigerated room, and the ambient temperature detected by the ambient temperature sensor is greater than or equal to the set temperature of the refrigerated room; or, if the indoor temperature of the refrigerated room detected by the indoor temperature sensor is greater than the set temperature of the refrigerated room, but the ambient temperature detected by the ambient temperature sensor is less than the set temperature of the refrigerated room, and the flow of people obtained based on the detection results of the human body sensor is greater than or equal to a preset flow value, then the refrigeration system is controlled to start refrigeration until the indoor temperature of the refrigerated room is less than or equal to the set temperature of the refrigerated room.

[0021] If the indoor temperature of the refrigerated room detected by the indoor temperature sensor is less than or equal to the set temperature of the refrigerated room, or if the indoor temperature of the refrigerated room detected by the indoor temperature sensor is greater than the set temperature of the refrigerated room, but the ambient temperature detected by the ambient temperature sensor is less than the set temperature of the refrigerated room, and the flow of people obtained based on the detection results of the human body sensor is less than the preset flow value, then the refrigeration system will not start refrigeration.

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

[0023] For automatic temperature control of refrigerated rooms, if a photosensitive sensor determines that the current period is a business day, an indoor temperature sensor monitors the indoor temperature of the refrigerated room and compares it with the set temperature. If the indoor temperature is less than or equal to the set temperature, the refrigeration system is not activated, meaning no cooling is needed. If the indoor temperature is greater than the set temperature, the ambient temperature is further compared to the set temperature. If the ambient temperature is also greater than or equal to the set temperature, the refrigeration system is activated to cool the room. If the ambient temperature is less than the set temperature, the ambient temperature might be used for cooling. However, since it's a business day, and considering the potential for many customers opening the beverage cooler to purchase items, leading to significant cold air loss, a human presence sensor is needed to monitor foot traffic. If the foot traffic is greater than or equal to a preset value, and the cold air loss from the beverage cooler is substantial, using only the ambient temperature may not meet the temperature requirements. Therefore, the refrigeration system must be activated to ensure the refrigerated room reaches the desired temperature. If the foot traffic is less than the preset flow rate, the beverage cabinet will not lose much cold air. In this case, the ambient temperature alone is sufficient to cool the refrigerated room, so the refrigeration system does not need to be activated. In other words, if the indoor temperature of the refrigerated room is higher than the set temperature, but the ambient temperature is lower than the set temperature and the foot traffic is less than the preset flow rate, the refrigeration system can still be deactivated, thus meeting the temperature requirements while reducing energy consumption.

[0024] In one embodiment of this application, when the current time period is a non-business period, controlling the refrigeration system based on the indoor temperature of the refrigerated room collected by the indoor temperature sensor, the set temperature of the refrigerated room, and the ambient temperature collected by the ambient temperature sensor, so that the indoor temperature of the refrigerated room is less than or equal to the set temperature of the refrigerated room, includes:

[0025] When the current period is a non-business period, if the indoor temperature of the refrigerated room collected by the indoor temperature sensor is greater than the set temperature of the refrigerated room, and the ambient temperature collected by the ambient temperature sensor is greater than or equal to the set temperature of the refrigerated room, then the refrigeration system is controlled to start refrigeration until the indoor temperature of the refrigerated room is less than or equal to the set temperature of the refrigerated room.

[0026] If the indoor temperature of the refrigerated room detected by the indoor temperature sensor is less than or equal to the set temperature of the refrigerated room, or if the indoor temperature of the refrigerated room detected by the indoor temperature sensor is greater than the set temperature of the refrigerated room, but the ambient temperature detected by the ambient temperature sensor is less than the set temperature of the refrigerated room, then the refrigeration system will not start refrigeration.

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

[0028] For automatic temperature control of refrigerated rooms, if a photosensitive sensor determines that the current period is a non-operational time, an indoor temperature sensor monitors the indoor temperature of the refrigerated room and compares it with the set temperature. If the indoor temperature is less than or equal to the set temperature, the refrigeration system is not activated, meaning no cooling is required. However, if the indoor temperature is greater than the set temperature, the ambient temperature is further compared to the set temperature. If the ambient temperature is also greater than or equal to the set temperature, the refrigeration system is activated to cool the room. If the ambient temperature is less than the set temperature, the refrigeration system is not activated; the ambient temperature can be used to cool the room, thus meeting the temperature requirements. In other words, if the indoor temperature is greater than the set temperature but the ambient temperature is less than the set temperature, the refrigeration system does not need to be activated; the ambient temperature is sufficient to meet the temperature requirements, reducing energy consumption.

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

[0030] When the current period is during business hours, if the indoor temperature of the heating room detected by the indoor temperature sensor is lower than the set temperature of the heating room, and the ambient temperature detected by the ambient temperature sensor is lower than or equal to the set indoor temperature; or, if the indoor temperature of the heating room detected by the indoor temperature sensor is lower than the set temperature of the heating room, but the ambient temperature detected by the ambient temperature sensor is higher than the set temperature of the heating room, and the flow of people obtained based on the detection results of the human body sensor is greater than or equal to a preset flow value, then 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.

[0031] If the indoor temperature of the heating room detected by the indoor temperature sensor is greater than or equal to the set temperature of the heating room, or if the indoor temperature of the heating room detected by the indoor temperature sensor is less than the set temperature of the heating room, but the ambient temperature detected by the ambient temperature sensor is greater than the set temperature of the heating room, and the flow of people obtained based on the detection results of the human body sensor is less than the preset flow value, then the heating system will not start heating.

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

[0033] For automatic temperature control of heated rooms, if a photosensitive sensor determines that the current period is a business day, an indoor temperature sensor monitors the indoor temperature of the heated room and compares it to the set temperature. If the indoor temperature is greater than or equal to the set temperature, the heating system remains inactive, meaning heating is not required. However, if the indoor temperature is lower than the set temperature, the ambient temperature is further compared to the set temperature. If the ambient temperature is also less than or equal to the set temperature, the heating system is activated to heat the heated room. If the ambient temperature is higher than the set temperature of the heating room, the ambient temperature can be used to heat the room. However, during business hours, considering the potential for many customers to open the beverage cooler and purchase items, this could lead to significant heat loss. Therefore, it's necessary to further monitor customer flow using human motion sensors. If the flow is greater than or equal to a preset value, and the heat loss from the beverage cooler is substantial, relying solely on the ambient temperature may not be sufficient to meet the temperature requirements. In this case, the heating system needs to be activated to maintain the required temperature. Conversely, if the flow is less than the preset value, heat loss from the beverage cooler is minimal, and relying solely on the ambient temperature is enough to meet the temperature requirements. Therefore, the heating system can be deactivated. In short, even if the ambient temperature is higher than the set temperature and the flow is less than the preset value, the heating system can be deactivated even if the indoor temperature of the heating room is lower than the set temperature, thus meeting the temperature requirements while reducing energy consumption.

[0034] In one embodiment of this application, when the current time period is a non-business period, controlling the heating system based on the indoor temperature of the heating room collected by the indoor temperature sensor, the set temperature of the heating room, 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 set temperature of the heating room, includes:

[0035] When the current period is a non-business period, if the indoor temperature of the heating room collected by the indoor temperature sensor is lower than the set temperature of the heating room, and the ambient temperature collected by the ambient temperature sensor is less than or equal to the set temperature of the heating room, then the heating system is controlled to start heating until the indoor temperature of the corresponding room is greater than or equal to the set temperature.

[0036] If the indoor temperature of the heating room detected by the indoor temperature sensor is greater than or equal to the set temperature of the heating room, or if the indoor temperature of the heating room detected by the indoor temperature sensor is less than the set temperature of the heating room, but the ambient temperature detected by the ambient temperature sensor is greater than the set temperature of the heating room, then the heating system will not start heating.

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

[0038] For automatic temperature control of heated rooms, if a photosensitive sensor determines that the current period is a non-operational time, an indoor temperature sensor monitors the indoor temperature of the heated room and compares it with the set temperature. If the indoor temperature is greater than or equal to the set temperature, the heating system remains inactive, meaning no heating is required. However, if the indoor temperature is lower than the set temperature, the ambient temperature is further compared to the set temperature. If the ambient temperature is also less than or equal to the set temperature, the heating system is activated to heat the room. If the ambient temperature is higher than the set temperature, the heating system is not activated; the ambient temperature can be used to heat the room, thus meeting the temperature requirements. In other words, if the indoor temperature is lower than the set temperature but the ambient temperature is higher, the heating system does not need to be activated, and the ambient temperature is sufficient to meet the temperature requirements, reducing energy consumption.

[0039] In one embodiment of this application, after determining that the current time period is a business period based on the light intensity of the environment where the beverage cabinet is located detected by the photosensitive sensor, the method further includes:

[0040] The set temperature of the cooling room is lowered and the temperature difference fluctuation range is reduced. The sum of the adjusted set temperature of the cooling room and the temperature difference fluctuation range is taken as the set temperature of the cooling room.

[0041] And / or, increase the set temperature of the heating room and decrease the temperature difference fluctuation range, and take the sum of the adjusted set temperature of the heating room and the temperature difference fluctuation range as the set temperature of the heating room.

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

[0043] After determining the current time period as a business day using a photosensor, and considering the higher temperature requirements for the refrigerated rooms during business hours, the set temperature for the refrigerated rooms can be lowered, and the temperature fluctuation range can be reduced. Specifically, the set temperature for the refrigerated rooms is automatically adjusted to a low temperature setting, and the temperature fluctuation range is adjusted to a small range. The sum of the adjusted set temperature and the temperature fluctuation range is then used as the set temperature for the refrigerated rooms. This ensures that the temperature control of the refrigerated rooms meets the requirements during business hours. Similarly, after determining the current time period as a business day using a photosensor, and considering the higher temperature requirements for the heating rooms during business hours, the set temperature for the heating rooms can be raised, and the temperature fluctuation range can be reduced. Specifically, the set temperature for the heating rooms is automatically adjusted to a high temperature setting, and the temperature fluctuation range is adjusted to a small range. The sum of the adjusted set temperature and the temperature fluctuation range is then used as the set temperature for the heating rooms. This ensures that the temperature control of the heating rooms meets the requirements during business hours.

[0044] In one embodiment of this application, after determining that the current time period is a non-business period based on the light intensity of the environment where the beverage cabinet is located detected by the photosensor, the method further includes:

[0045] The set temperature of the refrigeration room is increased, and the temperature difference fluctuation range is increased. The sum of the adjusted set temperature of the refrigeration room and the temperature difference fluctuation range is taken as the set temperature of the refrigeration room.

[0046] And / or, lower the set temperature of the heating room and increase the temperature difference fluctuation range, and take the sum of the adjusted set temperature of the heating room and the temperature difference fluctuation range as the set temperature of the heating room.

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

[0048] After determining that the current period is a non-operating time slot using a photosensor, and considering that the temperature requirements for the cooling rooms are lower during non-operating periods, the set temperature of the cooling rooms can be increased, and the temperature difference fluctuation range can be widened. Specifically, the set temperature of the cooling rooms is automatically adjusted to a high temperature setting, and the temperature difference fluctuation range is adjusted to a large range. The sum of the adjusted set temperature and the temperature difference fluctuation range is then used as the set temperature of the cooling rooms. This saves energy during non-operating periods. Similarly, after determining that the current period is a non-operating time slot using a photosensor, and considering that the temperature requirements for the heating rooms are lower during non-operating periods, the set temperature of the heating rooms can be decreased, and the temperature difference fluctuation range can be widened. Specifically, the set temperature of the heating rooms is automatically adjusted to a low temperature setting, and the temperature difference fluctuation range is adjusted to a large range. The sum of the adjusted set temperature and the temperature difference fluctuation range is then used as the set temperature of the heating rooms. This saves energy during non-operating periods.

[0049] In one embodiment of this application, the beverage cabinet further includes a lighting lamp disposed inside the cabinet. After determining that the current time period is a business period based on the light intensity of the environment where the beverage cabinet is located detected by the photosensor, the method further includes:

[0050] The lighting lamp is controlled to illuminate at a first brightness.

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

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

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

[0054] After determining the current time period as business hours using a photosensor, to save energy, the lighting can be controlled to operate at a lower initial brightness. Only when someone is detected approaching the beverage cabinet will the lighting brightness gradually increase from the initial brightness to a second brightness, illuminating the cabinet to facilitate customer selection. Conversely, when someone is detected moving away from the beverage cabinet, the lighting brightness will gradually decrease from the second brightness back to the initial brightness, again reducing energy consumption.

[0055] In one embodiment of this application, the beverage cabinet further includes a lighting lamp disposed inside the cabinet. After determining that the current time period is a non-business period based on the light intensity of the environment where the beverage cabinet is located detected by the photosensor, the method further includes:

[0056] The lighting is controlled to be in the off state;

[0057] When the human body sensor detects that someone is approaching the beverage cabinet, the 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;

[0058] When the human body sensor detects that someone is moving away from the beverage cabinet, the brightness of the light is controlled to gradually decrease from the second brightness to the first brightness according to the distance the person is moving away.

[0059] When it is detected that the duration of illumination at a first brightness is greater than or equal to a preset duration, the lighting is controlled to turn off.

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

[0061] After determining that the current period is a non-business period using a photosensor, the lights can be kept off to save energy. Only when someone is detected approaching the beverage cabinet will the light brightness gradually increase from off to a second brightness level, illuminating the cabinet for pedestrians. When someone is detected moving away from the cabinet, the light brightness gradually decreases from the second brightness level back to the first brightness level, and the lights are turned off after a preset delay if the duration of illumination at the first brightness level is greater than or equal to a preset time. This achieves energy savings while still providing illumination for those leaving the cabinet.

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

[0063] When a malfunction of the photosensitive sensor is detected, the refrigeration system is controlled based on the indoor temperature of the refrigeration room and the set temperature of the refrigeration room collected by the indoor temperature sensor, so that the indoor temperature of the refrigeration room is less than or equal to the set temperature of the refrigeration room; and / or the heating system is controlled based on the indoor temperature of the heating room and the set temperature of the heating room collected by the indoor temperature sensor, so that the indoor temperature of the heating room is greater than or equal to the set temperature of the heating room.

[0064] The system controls the switching on and off of the lighting fixtures according to preset on / off times.

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

[0066] If a photosensitive sensor malfunction is detected, the beverage cabinet's temperature control mode needs to be switched from environmental adaptive control mode to compartment set temperature control mode. This means that cooling and / or heating control will be based on the compartment's indoor temperature and set temperature. Additionally, the lighting control mode needs to be switched from environmental adaptive control mode to time control mode. This means that the lighting will be controlled according to preset on / off times. This will prevent the beverage cabinet's temperature and lighting control from malfunctioning due to a photosensitive sensor failure.

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

[0068] The cabinet, which serves as the supporting structure for the beverage cabinet, has internal compartments, including a refrigeration compartment and / or a heating compartment.

[0069] A refrigeration system, located inside the cabinet, is used to cool and reduce the temperature of the refrigeration room;

[0070] and / or a heating system, which is located inside the cabinet, for heating the heating room;

[0071] A photosensitive sensor, which is installed in the cabinet, is used to detect the light intensity of the environment in which the beverage cabinet is located;

[0072] A human body sensor is installed in the cabinet to detect whether someone is approaching or moving away from the beverage cabinet;

[0073] A temperature detection device includes an indoor temperature sensor and an ambient temperature sensor. The indoor temperature sensor is installed in the cooling room or the heating room to collect the indoor temperature of the cooling room or the heating room. The ambient temperature sensor is installed on the outer end face of the cabinet to collect the ambient temperature of the environment in which the cabinet is located.

[0074] The controller is electrically connected to the photosensitive sensor, the human body sensor, the temperature detection device, the refrigeration system and / or the heating system, and the controller is used to execute the control method described in any embodiment of this application.

[0075] The above technical solution has the following advantages or beneficial effects:

[0076] Since the controller of the beverage cabinet can execute the control method described in any embodiment of this application, that is, by setting a photosensitive sensor, a human body sensor and a temperature detection device in the cabinet body of the beverage cabinet, it can monitor the light intensity, ambient temperature, room temperature and flow of people in the environment where the beverage cabinet is located, and thus can make energy-saving adjustments to the temperature of each room of the beverage cabinet according to the monitoring results, so as to meet the room temperature requirements while reducing energy consumption.

[0077] In one embodiment of this application, the beverage cabinet further includes a lighting lamp disposed inside the cabinet and electrically connected to the controller.

[0078] The beverage cabinet also includes lighting, which is electrically connected to a controller. This allows the lighting brightness to be automatically adjusted according to changes in the surrounding environment, thus meeting the user's original lighting needs while reducing energy consumption.

[0089] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0090] It should be noted that although functional modules are divided in the device schematic diagram and a 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 aforementioned 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 commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0092] Beverage display cases, also known as beverage showcases, are used in shopping malls or convenience stores to display beverages. As people's living standards improve, the demand for a wide variety of beverages is increasing. Different beverages have different temperature requirements, and to meet these needs, supermarkets and convenience stores have a large number of refrigerated and heated display cases.

[0093] However, the temperature settings in beverage cabinets are currently fixed and cannot be automatically adjusted according to business hours or non-business hours, resulting in high energy consumption.

[0094] Based on this, this application proposes a control method for a beverage cabinet, which aims to make adaptive energy-saving adjustments to the temperature of each compartment of the beverage cabinet according to the monitored changes in light intensity, ambient temperature, room temperature and traffic flow, so as to meet the room temperature requirements while reducing energy consumption.

[0095] The beverage cabinet in this application embodiment can be a cold drink cabinet, a hot drink cabinet, a cold and warm cabinet, or a refrigeration or heating cabinet. The technical solution for the improved beverage cabinet in this application embodiment will be described in detail below.

[0096] Figure 1 This is a three-dimensional front view of a beverage cabinet according to an embodiment of this application. Figure 2 for Figure 1 A cross-sectional view.

[0097] Please see Figures 1 to 2 As shown, the beverage cabinet provided in this embodiment may include a cabinet body 1. The cabinet body 1 may adopt a hollow structure such as a cuboid. The cabinet body 1 forms the 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] Please see Figure 2 As shown, in some embodiments, the cabinet 1 may have several compartments inside. 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 multiple storage compartments.

[0099] Please see Figure 2 As shown, in some embodiments, the refrigeration compartment 11 and the heating compartment 12 can serve as independent storage spaces to meet different needs such as refrigeration or heating depending on the type of food, and to store items that require refrigeration or heating. The refrigeration compartment 11 and the heating compartment 12 can be arranged vertically or horizontally. The temperature of the refrigeration compartment 11 and the heating compartment 12 can be controlled independently.

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

[0101] Please see Figure 2 As shown, in some embodiments, the beverage cabinet may include a door 13. The door 13 may be hinged to the front of the cabinet 1 for opening and closing the refrigeration compartment 11 and the heating compartment 12.

[0102] It should be noted that multiple doors 13 can be installed. Doors 13 can be installed one-to-one with refrigeration compartments 11 and heating compartments 12. One or more doors 13 can be installed for one refrigeration compartment 11, and one or more doors 13 can be installed for one heating compartment.

[0103] Door 13 can be transparent. In other words, users can see the items placed in the refrigeration compartment 11 and the heating compartment 12 through door 13. This allows users to more easily select the beverages they need. Specifically, users can observe the location of an item in the refrigeration compartment 11 or heating compartment 12 before taking it out, allowing for quick removal after opening door 13. This shortens the opening time of door 13, reduces cold loss from the refrigeration compartment 11 and heat loss from the heating compartment 12, thereby reducing the frequency of compressor operation and lowering energy consumption.

[0104] In some embodiments, the door 13 may include a door frame and a glass panel, the glass panel being disposed within the door frame. This allows the items placed in the refrigeration compartment 11 or heating compartment 12 to be seen through the glass panel, and also enhances the aesthetic appearance of the beverage cabinet. Advantageously, the door frame may be a metal frame with a recessed groove within it, into which the glass panel may be disposed. Specifically, the outer edge of the glass panel may be disposed within the recess. The door frame may be provided with a door handle for easy opening and closing of the door 13.

[0105] In some embodiments, the glass panel may be double-glazed. This provides thermal insulation, reduces the loss of cold air from the cooling chamber 11 and the heat loss from the heating chamber 12, thereby reducing the frequency of compressor operation in the beverage cabinet and lowering its energy consumption.

[0106] In some embodiments, the beverage cabinet may include a refrigeration system. The refrigeration system may be located inside the cabinet body 1. The refrigeration system can be used to provide cold air to the interior of the refrigeration compartment 11 of the beverage cabinet to maintain a low-temperature environment in the refrigeration compartment 11. A refrigeration system is a system that uses refrigerant circulation to lower the temperature, and mainly includes major components such as a compressor, condenser, throttling element, and evaporator. The refrigeration system achieves a cooling effect by circulating refrigerant to transfer heat from a low-temperature object to a high-temperature object.

[0107] In some embodiments, the refrigeration system may include a compressor. The compressor may serve as a power source for the refrigeration cycle, drawing in low-temperature, low-pressure refrigerant gas and compressing it into a high-temperature, high-pressure gas. The compressor may deliver the high-temperature, high-pressure refrigerant to the condenser.

[0108] In some embodiments, the refrigeration system may include a condenser (not shown). The condenser can be used to receive refrigerant flowing from the compressor, cooling the high-temperature, high-pressure refrigerant gas from the compressor and converting it into a liquid state. The condenser can transfer heat from the refrigerant to the surrounding air, thus lowering the temperature of the refrigerant.

[0109] In some embodiments, the refrigeration system may include a throttling device (not shown). A condenser can deliver condensed refrigerant to the throttling device. The throttling device may be a capillary tube. The throttling device can be used to reduce the pressure of the refrigerant.

[0110] In some embodiments, the compressor, condenser, throttling device, and evaporator can be connected in sequence to form a refrigeration circuit. The refrigerant can circulate within the refrigeration circuit to cool the refrigeration chamber 11 inside the cabinet 1.

[0111] In some embodiments, the beverage cabinet may include a heating system. The heating system may be located inside the cabinet body 1. The heating system can be used to provide hot air to the interior of the heating compartment of the beverage cabinet to maintain a higher temperature environment in the heating compartment 11. The heating system is a system that uses refrigerant circulation to raise the temperature, and mainly includes major components such as a compressor, condenser, expansion valve, evaporator, and heating element.

[0112] The heating system utilizes air circulation to transfer heat energy, transferring the heat generated by the heating element to the heating chamber 12 to achieve the purpose of heating. Specifically, the heating system adopts the principle of refrigerant circulation heating. First, an electronic diaphragm compressor compresses the refrigerant into a high-pressure gas. Then, a condenser cools the high-temperature, high-pressure gas into a high-pressure liquid refrigerant. Next, an expansion valve reduces the pressure, turning the high-pressure liquid refrigerant into a low-pressure liquid refrigerant. Finally, an evaporator turns the low-temperature, low-pressure refrigerant into a low-temperature, low-pressure gaseous refrigerant. During this process, the heating element absorbs heat from the air and then transfers this heat to the objects in the heating chamber 12 that need to be heated.

[0113] In some embodiments, see Figure 2The beverage cabinet also includes a photosensor 14, which is located on the cabinet body 1, such as on the front or side faces of the cabinet body 1. The photosensor 14 can also be located on the door 13. The photosensor 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 when there is light around the beverage cabinet 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 photosensor 14 detects that there is light in the environment in which the beverage cabinet is located, the current period can be determined to be a business period. When the photosensor 14 detects that there is no light in the environment in which the beverage cabinet is located, the current period can be determined to be a non-business period. Alternatively, when the photosensor 14 detects that the light intensity in the environment in which the beverage cabinet is located is greater than or equal to a preset light intensity, the current period can be determined to be a business period. When the photosensor 14 detects that the light intensity in the environment in which the beverage cabinet is located is less than a preset light intensity, the current period can be determined to be a non-business period.

[0114] In some embodiments, see Figure 2 The beverage cabinet also includes a human body sensor 15, which is located on the cabinet body 1, such as on the front surface of the cabinet body 1. The human body sensor 15 is used to detect whether someone is approaching or moving away from the beverage cabinet. Based on the detection results of the human body sensor 15, the flow of people can be counted, and then the cooling system and / or heating system of the beverage cabinet can be controlled for energy saving based on the flow of people.

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

[0116] In one embodiment of this application, see [reference] Figure 2 The beverage cabinet also includes a lighting fixture 17, which is installed inside the cabinet body 1 to illuminate each compartment of the beverage cabinet, facilitating the display of the beverages inside. The environment surrounding the beverage cabinet can be monitored by a photosensitive sensor 14 and a human body sensor 15, allowing for automatic adjustment of the lighting brightness based on changes in the surrounding environment. This satisfies the user's original lighting needs while reducing energy consumption.

[0117] Reference Figure 3 , Figure 3 This is a flowchart of a control method for a beverage cabinet provided in an embodiment of this application. The method is executed by the beverage cabinet provided in this embodiment, including but not limited to steps S310 to S330.

[0118] Step S310: Determine whether the current time period is a business period based on the light intensity of the environment where the beverage cabinet is located, as detected by the photosensitive sensor.

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

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

[0121] In this embodiment, the light intensity of the environment surrounding the beverage cabinet, detected by a photosensitive sensor, determines whether the current time period is a business day. When a business day is determined, the cooling and / or heating systems are controlled based on the indoor temperature of the compartment (collected by an indoor temperature sensor), the set temperature of the compartment, the ambient temperature (collected by an ambient temperature sensor), and the pedestrian flow statistics based on the detection results of a human body sensor. When a non-business day is determined, the cooling and / or heating systems are controlled based on the indoor temperature of the compartment (collected by an indoor temperature sensor), the set temperature of the compartment, and the ambient temperature (collected by an ambient temperature sensor). This allows for adaptive environmental energy-saving temperature adjustment of each compartment of the beverage cabinet according to business or non-business hours, effectively reducing energy consumption.

[0122] Example 1

[0123] Reference Figure 4 , Figure 4 This is a flowchart of the control method for a beverage cabinet provided in Embodiment 1 of this application. The method is executed by the beverage cabinet provided in this embodiment, including but not limited to steps S410 to S4120.

[0124] Step S410: Detect whether there is light in the environment where the beverage cabinet is located using a photosensitive sensor;

[0125] Step S420: If light is detected in the environment where the beverage cabinet is located, then the current time period is determined to be the business period.

[0126] Step S430: When the current time period is a business period, determine whether the indoor temperature of the refrigerated room collected by the indoor temperature sensor is less than or equal to the set temperature of the refrigerated room.

[0127] Step S440: If the indoor temperature of the cooling room is greater than the set temperature of the cooling room, then determine whether the ambient temperature collected by the ambient temperature sensor is less than the set temperature of the cooling room.

[0128] Step S450: If the ambient temperature is lower than the set temperature of the cooling room, determine whether the flow of people obtained by the detection results of the human body sensor is greater than or equal to the preset flow value.

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

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

[0131] Step S480: If it is detected that there is no light in the environment where the beverage cabinet is located, then it is determined that the current time period is a non-business period;

[0132] Step S490: When the current time period is a non-business period, determine whether the indoor temperature of the refrigerated room collected by the indoor temperature sensor is less than or equal to the set temperature of the refrigerated room.

[0133] Step S4100: If the indoor temperature of the cooling room is greater than the set temperature of the cooling room, then determine whether the ambient temperature collected by the ambient temperature sensor is less than the set temperature of the cooling room.

[0134] Step S4110: If the ambient temperature is greater than or equal to the set temperature of the cooling room, control the cooling system to start cooling until the indoor temperature of the cooling room is less than or equal to the set temperature of the cooling room.

[0135] In step S4120, if the ambient temperature is lower than the set temperature of the cooling room, or the indoor temperature of the cooling room is less than or equal to the set temperature of the cooling room, the cooling system is controlled not to start cooling.

[0136] In this embodiment, for the automatic temperature regulation of the refrigerated room, if a photosensitive sensor determines that the current time period is a business period, an indoor temperature sensor monitors the indoor temperature of the refrigerated room and compares it with the set temperature of the refrigerated room. If the indoor temperature of the refrigerated room is less than or equal to the set temperature, the refrigeration system is not activated, i.e., no cooling is required. However, if the indoor temperature of the refrigerated room is greater than the set temperature, the ambient temperature is further compared with the set temperature. If the ambient temperature is also greater than or equal to the set temperature, the refrigeration system is activated to cool the refrigerated room. Specifically, the compressor and fan can be controlled to gradually increase their power by 50%, 80%, and 100% according to the decreasing trend of the indoor temperature of the room to achieve cooling. If the ambient temperature is lower than the set temperature of the cooling room, the ambient temperature can be used to cool the room. However, during business hours, considering the potential for many customers to open the beverage cooler and purchase items, leading to significant heat loss, it's necessary to further monitor foot traffic using human motion sensors. If the foot traffic is greater than or equal to the preset flow rate, and the heat loss from the beverage cooler is substantial, relying solely on the ambient temperature may not meet the temperature requirements. In this case, the cooling system needs to be activated to maintain the required temperature. Specifically, the compressor and fan can be controlled to operate at 100% power and high speed for rapid cooling. Conversely, if the foot traffic is less than the preset flow rate, and the heat loss from the beverage cooler is minimal, relying solely on the ambient temperature is sufficient to meet the temperature requirements. Therefore, the cooling system can be deactivated. In short, if the indoor temperature of the cooling room is higher than the set temperature, but the ambient temperature is lower than the set temperature and the foot traffic is less than the preset flow rate, the cooling system can be deactivated to meet the temperature requirements while reducing energy consumption.

[0137] If a photosensitive sensor determines that the current period is outside of business hours, an indoor temperature sensor monitors the indoor temperature of the refrigerated room and compares it to the set temperature. If the indoor temperature is less than or equal to the set temperature, the refrigeration system remains inactive, meaning no cooling is required. However, if the indoor temperature is greater than the set temperature, the ambient temperature is compared to the set temperature. If the ambient temperature is also greater than or equal to the set temperature, the refrigeration system is activated to cool the room. Specifically, the compressor and fan can be controlled to operate at 50% power. If the ambient temperature is lower than the set temperature, the refrigeration system does not need to be activated; the ambient temperature can be used to cool the room, thus meeting its temperature requirements. In other words, if the indoor temperature is higher than the set temperature, but the ambient temperature is lower, the refrigeration system does not need to be activated; the ambient temperature is sufficient to meet the temperature requirements, reducing energy consumption.

[0138] Example 2

[0139] Reference Figure 5 , Figure 5 This is a flowchart of the control method for a beverage cabinet provided in Embodiment 2 of this application. The method is executed by the beverage cabinet provided in this embodiment, including but not limited to steps S510 to S5140.

[0140] Step S510: Detect whether there is light in the environment where the beverage cabinet is located using a photosensitive sensor;

[0141] Step S520: If light is detected in the environment where the beverage cabinet is located, then the current time period is determined to be the business period.

[0142] Step S530: When the current time period is a business period, the set temperature of the refrigerated room is lowered and the temperature difference fluctuation range is reduced, and the sum of the adjusted set temperature of the refrigerated room and the temperature difference fluctuation range is used as the set temperature of the refrigerated room.

[0143] Step S540: Determine whether the indoor temperature of the cooling room collected by the indoor temperature sensor is less than or equal to the set temperature of the cooling room.

[0144] Step S550: If the indoor temperature of the cooling room is greater than the set temperature of the cooling room, then determine whether the ambient temperature collected by the ambient temperature sensor is less than the set temperature of the cooling room.

[0145] Step S560: If the ambient temperature is lower than the set temperature of the cooling room, determine whether the flow of people obtained by the detection results of the human body sensor is greater than or equal to the preset flow value.

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

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

[0148] Step S590: If it is detected that there is no light in the environment where the beverage cabinet is located, then it is determined that the current time period is a non-business period;

[0149] Step S5100: When the current time period is a non-business period, the set temperature of the refrigeration room is increased and the temperature difference fluctuation range is increased, and 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.

[0150] Step S5110: Determine whether the indoor temperature of the cooling room collected by the indoor temperature sensor is less than or equal to the set temperature of the cooling room.

[0151] Step S5120: If the indoor temperature of the cooling room is greater than the set temperature of the cooling room, then determine whether the ambient temperature collected by the ambient temperature sensor is less than the set temperature of the cooling room.

[0152] Step S5130: If the ambient temperature is greater than or equal to the set temperature of the cooling room, control the cooling system to start cooling until the indoor temperature of the cooling room is less than or equal to the set temperature of the cooling room.

[0153] In step S5140, if the ambient temperature is lower than the set temperature of the cooling room, or the indoor temperature of the cooling room is less than or equal to the set temperature of the cooling room, the cooling system is controlled not to start cooling.

[0154] In this embodiment, for the automatic temperature adjustment of the refrigerated room, if the current time period is determined to be a business period by a photosensitive sensor, considering that the temperature requirements for the refrigerated room are higher during business hours, the set temperature of the refrigerated room can be lowered and the temperature difference fluctuation range can be reduced. That is, the set temperature of the refrigerated room is automatically adjusted to a low temperature setting, 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 refrigerated room and the temperature difference fluctuation range is taken as the set temperature of the refrigerated room. This ensures that the temperature control of the refrigerated room can meet the temperature requirements during business hours. The indoor temperature of the refrigerated room is then monitored by an indoor temperature sensor and compared with the set temperature of the refrigerated room. If the indoor temperature of the refrigerated room is less than or equal to the set temperature, the refrigeration system is not activated, i.e., no refrigeration is required. However, if the indoor temperature of the refrigerated room is greater than the set temperature, the comparison between the ambient temperature and the set temperature needs to be further determined. If the ambient temperature is also greater than or equal to the set temperature, the refrigeration system needs to be activated to refrigerate the refrigerated room. Specifically, the compressor and fan can be controlled to gradually increase their power by 50%, 80%, and 100% according to the decreasing trend of the room's indoor temperature to achieve cooling. If the ambient temperature is lower than the set temperature of the cooling room, the ambient temperature can be used to cool the room. However, since it is during business hours, considering that many customers may open the beverage cabinet to purchase items, leading to significant heat loss, it is necessary to further monitor the flow of people using human body sensors. If the flow of people is greater than or equal to the preset flow value, the heat loss from the beverage cabinet is significant, and using only the ambient temperature to cool the room may not meet the temperature requirements. Therefore, the cooling system needs to be activated to ensure the required temperature in the cooling room. Specifically, the compressor and fan can be controlled to run at 100% power and high speed for rapid cooling. If the flow of people is less than the preset flow value, the heat loss from the beverage cabinet is minimal, and using only the ambient temperature to cool the room is sufficient. Therefore, the cooling system does not need to be activated. If the indoor temperature of the refrigerated room is higher than the set temperature, but the ambient temperature is lower than the set temperature and the foot traffic is lower than the preset value, the refrigeration system can remain in operation without activating, thus meeting temperature requirements while reducing energy consumption. If a photosensitive sensor determines the current time period is non-business hours, considering the lower temperature requirements for the refrigerated room during these times, the set temperature can be increased, and the temperature fluctuation range can be widened. This means the set temperature is automatically adjusted to a high-temperature setting, and the temperature fluctuation range is adjusted to a large range. The sum of the adjusted set temperature and the temperature fluctuation range is then used as the set temperature. This saves energy during non-business hours. The indoor temperature sensor is then used to monitor the indoor temperature of the refrigerated room and compare it to the set temperature.If the indoor temperature of the cooling room is less than or equal to the set temperature, the refrigeration system will not start, meaning no cooling is required. However, if the indoor temperature is greater than the set temperature, the ambient temperature must be compared to the set temperature. If the ambient temperature is also greater than or equal to the set temperature, the refrigeration system will start to cool the room. Specifically, the compressor and fan can be controlled to operate at 50% power to achieve cooling. If the ambient temperature is less than the set temperature, the refrigeration system does not need to be started; the ambient temperature can be used to cool the room, thus meeting the temperature requirements. In other words, if the indoor temperature of the cooling room is greater than the set temperature, but the ambient temperature is less than the set temperature, the refrigeration system does not need to be started; the ambient temperature is sufficient to meet the temperature requirements, reducing energy consumption.

[0163] Step S670: If the flow of people is less than the preset flow value, or the indoor temperature of the heating room is greater than or equal to the set temperature of the heating room, then control the heating system not to start heating.

[0165] Step S690: When the current time period is a non-business period, determine whether the indoor temperature of the heating room collected by the indoor temperature sensor is lower than the set temperature of the heating room.

[0166] Step S6100: If the indoor temperature of the heating room is less than the set temperature of the heating room, then determine whether the ambient temperature collected by the ambient temperature sensor is less than or equal to the set temperature of the heating room.

[0167] Step S6110: If the ambient temperature is less than or equal to the set temperature of the heating room, control the heating system to start heating until the indoor temperature of the heating room is greater than or equal to the set temperature of the heating room.

[0168] In step S6120, if the ambient temperature is greater than the set temperature of the heating room, 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.

[0169] In this embodiment, for the automatic temperature regulation of the heating room, if the current time period is determined to be a business period by a photosensitive sensor, the indoor temperature of the heating room is monitored by an indoor temperature sensor and compared with the set temperature of the heating room.

If the ambient temperature is higher than the set temperature of the heating room, the ambient temperature can be used to raise the temperature of the heating room. However, since it is during business hours, and considering that many customers may open the beverage cooler to purchase items, resulting in significant heat loss, it is necessary to further monitor the flow of people using human body sensors. If the flow of people is greater than or equal to the preset flow value, and the heat loss from the beverage cooler is substantial, simply using the ambient temperature to raise the temperature of the heating room may not be sufficient. Therefore, it is necessary to activate the heating system to ensure the required temperature in the heating room. Specifically, the compressor and heating element can be controlled to operate at 100% power and high speed to achieve rapid heating. Conversely, if the flow of people is less than the preset flow value, the heat loss from the beverage cooler is minimal, and using the ambient temperature alone is sufficient to raise the temperature of the heating room. Therefore, the heating system does not need to be activated. In other words, if the indoor temperature of the heating room is lower than the set temperature of the heating room, but the ambient temperature is higher 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 left unstarted to heat the room, thus meeting the temperature requirements while reducing energy consumption.

[0170] If a photosensor determines that the current period is outside of business hours, an indoor temperature sensor monitors the indoor temperature of the heating room and compares it to the set temperature. If the indoor temperature is greater than or equal to the set temperature, the heating system remains inactive, meaning heating is not required.

[0186] In step S7140, if the ambient temperature is greater than the set temperature of the heating room, 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.

[0187] In this embodiment, for the automatic temperature adjustment of the heating room, if the current time period is determined to be a business period by a photosensitive sensor, considering that the temperature requirements for the heating room are higher during business hours, 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 a high temperature level, and the temperature difference fluctuation range is adjusted to a small temperature difference fluctuation range. Then, the sum of the adjusted set temperature and the temperature difference fluctuation range is taken as the set temperature of the heating room. This ensures that the temperature control of the heating room can meet the temperature requirements during business hours. The indoor temperature of the heating room is then monitored by an indoor temperature sensor and compared with the set temperature. If the indoor temperature of the heating room is greater than or equal to the set temperature, the heating system is not activated, i.e., heating is not required. However, if the indoor temperature of the heating room is less than the set temperature, the comparison between the ambient temperature and the set temperature needs to be further determined. If the ambient temperature is also less than or equal to the set temperature, the heating system needs to be activated to heat the heating room. Specifically, the compressor and heating element can be controlled to gradually increase their power by 50%, 80%, and 100% according to the rising trend of the room's indoor temperature to achieve heating. If the ambient temperature is higher than the set temperature of the heating room, the ambient temperature can be used to raise the temperature of the heating room. However, since it is during business hours, considering that many customers may open the beverage cabinet to buy items, resulting in significant heat loss from the cabinet, it is necessary to further monitor the flow of people using human body sensors. If the flow of people is greater than or equal to the preset flow value, the beverage cabinet will lose a lot of heat, and using only the ambient temperature to raise the temperature of the heating room may not be sufficient. Therefore, the heating system needs to be activated to ensure that the temperature of the heating room meets 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 beverage cabinet will not lose much heat, and using only the ambient temperature to raise the temperature of the heating room will be sufficient. Therefore, the heating system does not need to be activated. In other words, if the indoor temperature of the heating room is lower than the set temperature of the heating room, but the ambient temperature is higher 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 left unstarted to heat the room, thus meeting the temperature requirements while reducing energy consumption.

[0188] If the photosensitive sensor determines that the current time period is a non-business period, considering that the temperature requirements for the heating room are lower during non-business periods, 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 a low-temperature setting, and the temperature difference fluctuation range is adjusted to a large temperature difference fluctuation range. Then, the sum of the adjusted set temperature and the temperature difference fluctuation range is taken as the set temperature of the heating room. This can save energy during non-business periods. Next, the indoor temperature of the heating room is monitored by an indoor temperature sensor and compared with the set temperature. If the indoor temperature of the heating room is greater than or equal to the set temperature, the heating system is not activated, i.e., no heating is required. If the indoor temperature of the heating room is lower than the set temperature, the comparison between the ambient temperature and the set temperature needs to be further determined. If the ambient temperature is also less than or equal to the set temperature, the heating system needs to be activated to heat the heating room. Specifically, the compressor and 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, there is no need to start the heating system. The ambient temperature can be used to heat the heating room, thus meeting the temperature requirements. In other words, if the indoor temperature of the heating room is lower than the set temperature, but the ambient temperature is higher, the heating system does not need to be started, and the ambient temperature can be used to meet the temperature requirements, thereby reducing energy consumption.

[0189] Example 5

[0190] Reference Figure 8 , Figure 8 This is a flowchart of the control method for a beverage cabinet provided in Embodiment 5 of this application. The method is executed by the beverage cabinet provided in this embodiment, including but not limited to steps S810 to S8140.

[0191] Step S810: Detect whether there is light in the environment where the beverage cabinet is located using a photosensitive sensor;

[0192] Step S820: If light is detected in the environment where the beverage cabinet is located, then the current time period is determined to be the business period.

[0193] Step S830: When the current time period is a business period, control the lighting to illuminate at the first brightness.

[0194] Step S840: Detect whether someone is approaching the beverage cabinet using a human body sensor;

[0195] Step S850: If someone is detected approaching the beverage cabinet, control the brightness of the lighting to gradually increase from the first brightness to the second brightness according to the distance of the person approaching.

[0196] Step S860: Detect whether someone has moved away from the beverage cabinet using a human body sensor;

[0197] Step S870: If someone is detected moving away from the beverage cabinet, control the brightness of the lighting to gradually decrease from the second brightness to the first brightness according to the distance the person moves away.

[0198] Step S880: If it is detected that there is no light in the environment where the beverage cabinet is located, then it is determined that the current time period is a non-business period;

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

[0200] Step S8100: Detect whether someone is approaching the beverage cabinet using a human body sensor;

[0201] Step S8110: If someone is detected approaching the beverage cabinet, control the brightness of the lighting to gradually increase from the off state to the second brightness according to the distance of the person approaching;

[0202] Step S8120: Detect whether someone has moved away from the beverage cabinet using a human body sensor;

[0203] Step S8130: If someone is detected moving away from the beverage cabinet, control the brightness of the lighting to gradually decrease from the second brightness to the first brightness according to the distance the person moves away.

[0204] Step S8140: Detect whether the duration of illumination at the first brightness is greater than or equal to a preset duration. If the duration of illumination at the first brightness is greater than or equal to the preset duration, return to step S890.

[0205] In this embodiment, after the photosensor determines that the current period is a business day, to save energy, the lighting can be controlled to operate at a lower initial brightness. Only when someone is detected approaching the beverage cabinet will the lighting brightness gradually increase from the initial brightness to a second brightness, illuminating the beverage cabinet to facilitate customer selection. When someone is detected moving away from the beverage cabinet, the lighting brightness will gradually decrease from the second brightness back to the initial brightness, illuminating the cabinet to facilitate customer selection. Specifically, after the photosensor determines that the current period is a business day, PWM adjustment can be used to control the lighting to operate at 30% power to achieve energy saving. When the human body sensor detects someone approaching the beverage cabinet, the lighting is controlled to gradually illuminate at 30%, 50%, 80%, and 100% of the power according to the person's approach distance, using PWM adjustment, to facilitate beverage selection. When the human body sensor detects that a person has left the beverage cabinet, the brightness of the lighting is gradually reduced by PWM adjustment according to 100%, 80%, 50%, and 30% of the power of the lighting, and finally controlled to maintain the lighting at a low power of 30% to facilitate the display of beverages in the cabinet during business hours.

[0206] After determining that the current period is a non-business period using a photosensor, the lights can be kept off to save energy. Only when someone is detected approaching the beverage dispenser will the light brightness gradually increase from off to a second brightness level, illuminating the dispenser for pedestrians. When someone moves away from the dispenser, the light brightness gradually decreases from the second brightness level back to the first brightness level, and the lights are turned off after a preset delay if the duration of illumination at the first brightness level is greater than or equal to a preset time. This achieves energy saving while still providing convenient lighting for those leaving. Specifically, when the photosensor determines that the current period is a non-business period with low foot traffic, the lights are turned off. If a human body sensor detects someone approaching the beverage dispenser, the lights are adjusted using PWM to gradually increase the power from 30%, 50%, 80%, and 100% according to the person's approach distance, saving energy and providing convenience for people retrieving drinks at night. When the human body sensor detects that a person has left, the brightness of the light is gradually reduced by PWM adjustment according to 100%, 80%, 50%, and 30% of the light power. When the light power drops to 30%, it is turned off after a preset time delay, so as to provide lighting for people who have left.
