Technical Field
[0001] This utility model relates to the technical field of beverage storage and display equipment, and in particular to a hot and cold beverage cabinet. Background Technology
[0002] Existing household and commercial beverage storage equipment generally only has single functions such as refrigeration, heating, or insulation. It is suitable for large or multi-functional spaces with ample room, but not for spaces with limited space. Because the actual needs for equipment vary in different seasons, some equipment may become unused during seasonal changes. Utility Model Content
[0003] The technical problem to be solved by this utility model is: In order to overcome the above-mentioned technical problems, this utility model provides a hot and cold beverage cabinet that integrates refrigeration, heating and heat preservation, is multi-functional, saves space, and can be widely used in space-constrained places such as high-speed rail passenger transport and air transport.
[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a hot and cold beverage cabinet, including a cabinet body and a door panel. The cabinet body has a storage space with an opening on one side. The door panel is located at the opening to open and close the storage space. It also includes a refrigeration system, a heating system, a thermostat, and a control box. The cabinet body has a back panel and multiple layers of frames. The frames are located on the back panel, and each frame divides the interior of the cabinet body into multiple vertically distributed storage spaces. Air inlets are provided on the back panel facing each storage space. The cabinet body has insulation layers at the corresponding storage spaces. The refrigeration system includes a refrigeration unit, which includes a variable frequency compressor. The variable frequency compressor is located at the bottom of the cabinet body. The storage spaces below the cabinet body are refrigerator compartments, and the storage spaces above the cabinet body are heating and insulation compartments. The refrigerator compartments and the heating and insulation compartments are separated by an insulation layer. One end of the insulation layer extends into the interior space of the back panel and divides the interior space of the back panel into upper and lower parts. The unit is divided into two sections: the upper section is the heating installation space, and the lower section is the cold air intake space. A variable frequency compressor drives the refrigerant circulation, and the cold air from the refrigeration unit enters the cold storage compartment from the air inlets of each storage space. The heating system includes a heating plate and a circulating fan, both of which are located within the heating installation space. An air outlet is located on the side of the back panel facing the heating and insulation compartment, with the circulating fan positioned at the outlet and the heating plate positioned at the air inlet of the storage space containing the heating and insulation compartment. A temperature sensor is located outside the cabinet and is connected to a temperature controller, which in turn is connected to a control box.
[0005] The insulation layer is made of polyurethane foam insulation material, which reduces cold loss and saves more than 40% of energy.
[0006] The heating plate is a PLC ceramic heating plate.
[0007] The door panel is a double-layered tempered glass structure with central control, which facilitates the display of goods inside the cabinet. The inside of the door panel is equipped with a glass heat tracing film, which can eliminate condensation caused by the temperature difference between the inside and outside of the glass during the refrigeration function, ensuring that no condensation occurs on the cabinet door during refrigerated display operations.
[0008] The heating plate has a temperature measuring module, which is connected to the temperature controller circuit. A temperature control switch and a fuse are connected in series in the path between the temperature measuring module and the temperature controller.
[0009] The breaking temperature limit of the temperature control switch is 85℃, and the melting temperature limit of the fuse is 150℃. The temperature control switch is reversible after it breaks, while the fuse is irreversible after it blows.
[0010] The beneficial effects of this utility model are that the hot and cold beverage cabinet can adjust the temperature of each storage space according to seasonal changes. Users do not need to purchase separate hot and cold beverage machines; one device meets diverse needs, making it especially suitable for spaces with limited space, such as offices, convenience stores, high-speed rail stations, and air transport locations. It supports mixing hot and cold beverages to meet personalized needs. The integrated design of the hot and cold beverage cabinet reduces overall energy consumption compared to two separate machines.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0017] like Figures 1-2As shown, this utility model discloses a hot and cold beverage cabinet, including a cabinet body 1 and a door panel 6. The cabinet body 1 has a storage space with an opening on one side. The door panel 6 is located at the opening to open and close the storage space. It also includes a refrigeration system, a heating system, a thermostat 4, and a control box 5. The cabinet body 1 has a back panel 11 and multiple layers of shelves 7 inside. The shelves 7 are used for storing refrigerated beverages, wines, etc. The shelves 7 are located on the back panel 11, and each shelf 7 divides the interior of the cabinet body 1 into multiple vertically distributed storage spaces 8.
[0018] The back panel 11 has air inlets facing each of the storage spaces 8. The cabinet 1 has insulation layers at the corresponding storage spaces 8. The refrigeration system includes a refrigeration unit 2, which comprises a variable frequency compressor M1, a condenser fan M2, and an evaporator fan M3. All three components are located at the bottom of the cabinet 1. The variable frequency compressor M1 drives the refrigerant circulation. The refrigeration system uses a high-performance variable frequency intelligent compressor, which is low-noise and highly efficient. The 3D three-dimensional refrigeration cycle ensures uniform and stable temperature and better preservation.
[0019] The storage spaces 8 below cabinet 1 are refrigerator compartments, while the storage spaces 8 above cabinet 1 are heated and insulated compartments. For example... Figures 1-2 In the illustrated embodiment, the topmost storage space 8 is a heating and insulation chamber, and the two lower storage spaces 8 are cold storage chambers. The cold storage chambers and the heating and insulation chambers are separated by an insulation panel 12. One end of the insulation panel 12 extends into the interior space of the back panel 11 and divides the interior space of the back panel 11 into upper and lower parts. The upper part is the heating installation space, and the lower part is the cold air entry space. The variable frequency compressor M1 drives the refrigerant circulation, and the cold air from the refrigeration unit 2 enters the cold storage chamber from the air inlets 9 of each storage space 8 where the cold storage chamber is located.
[0020] The heating system includes a heating plate 3 and a circulating fan M4, both of which are installed within the heating installation space. An air outlet 10 is located on the side of the back panel 11 facing the heating and insulation chamber, and the circulating fan M4 is positioned at the air outlet 10. The heating plate 3 is located at the air inlet 9 of the storage space 8 where the heating and insulation chamber is located. The heating plate 3 is positioned at the air inlet, and the circulating fan M4 is positioned at the air outlet, enabling circulating air intake and exhaust.
[0021] This utility model's hot and cold beverage cabinet employs an independent refrigeration system to cool the interior of the refrigerator compartment and an independent heating system to heat or maintain the temperature of the heating and insulation compartment. The refrigerator compartment and the heating and insulation compartment are temperature-isolated from each other by the insulation layer 12 and the heat insulation layer of each storage space 8. At the same time, the heating system and the refrigeration system are also separated by the insulation layer 12 on the back panel 11, making them independent and not affecting each other.
[0022] A temperature sensor is installed on the outside of the cabinet 1. The temperature sensor is connected to the temperature controller 4, and the temperature controller 4 is connected to the control box 5.
[0023] The insulation layer is made of polyurethane foam insulation material, which reduces heat loss and saves more than 40% of energy.
[0024] Heating plate 3 is a PLC ceramic heating plate. The heating system uses a high-performance, low-loss PTC ceramic heating plate, combined with a circulating fan M4, ensuring fast heating and reliable operation. The PLC ceramic heating plate operates stably and has its own temperature control function, allowing it to maintain the temperature within a specific range in suitable spaces, thus saving energy consumption.
[0025] Door panel 6 is a double-layered tempered glass structure with central control, which facilitates the display of goods inside the cabinet. The interior of door panel 6 is equipped with a glass heat tracing film, which can eliminate condensation caused by the temperature difference between the inside and outside of the glass during the refrigeration function, ensuring that the cabinet door will not produce condensation during refrigeration display.
[0026] Heating plate 3 has a temperature sensing module, which is electrically connected to temperature controller 4. A temperature control switch and a fuse are connected in series in the path between the temperature sensing module and temperature controller 4. Over-temperature protection is achieved through the temperature control switch and fuse. The first-level protection is a resettable structure of the temperature control switch, with a temperature of 85°C. The second-level protection is a non-resettable fuse protection, with a protection temperature of 150°C. The temperature control switch is a KSD301 snap-action temperature control switch. Figure 3 The KSD301 in the middle is the temperature control switch.
[0027] The power supply system of the hot and cold beverage cabinet of this utility model is AC220V, 50Hz; the power of the refrigeration unit is less than 400W; and the power of the electric heating element is less than 800W. Figure 3 In the diagram, L, N, and PE represent the live wire, neutral wire, and grounding protection wire of the three-phase power supply, respectively. NTC1 and NTC2 are both thermistors; NTC1 measures the temperature of the refrigerator compartment, and NTC2 measures the temperature of the compartment containing the hot and cold beverage cabinet. NTC2 is the temperature sensor installed outside cabinet 1. KT is a relay, K1 is a rocker switch, HP1 is a switch, QF is a miniature circuit breaker, TC is a power module, LED is an indicator light, M1 is a variable frequency compressor, M2 is a condenser fan, M3 is an evaporator fan, M4 is a circulating fan, and M5 is a heating resistor. Thermostat 4 uses the XR75CX temperature controller from Guangzhou Kang Sheng Refrigeration Equipment Co., Ltd., AC230V±10%, 50 / 60HZ.
[0028] This utility model discloses a hot and cold beverage cabinet that can be configured with automatic and manual control modes. Manual control allows for manual switching between cooling and heating functions based on seasonal ambient temperature, providing energy to the cabinet body 1. In manual control mode, heating and cooling are interlocked; that is, when the refrigerator compartment is operating, the heating and insulation compartment is at room temperature; when the heating and insulation compartment is operating, the refrigerator compartment is at room temperature. Figure 3 The automatic control is achieved through a relay KT. The temperature sensor installed outside the cabinet 1 senses and transmits the ambient temperature, which is analyzed and processed by the control box 5 to automatically set the storage temperature of cold or hot drinks in the cabinet according to the customer's needs. Then, the thermostat 4 adjusts the working mode of the refrigeration system and the heating system.
[0029] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
