The self-pickup cabinet body is the basic framework of this solution. While providing a place for the installation of various mechanisms, it also provides storage space for fresh food and boxed lunches. The purpose of setting up a combined cold and hot supply mechanism is to provide both cold and hot storage environments for the self-service cabinet body; the purpose of setting up a heat and cold circulation mechanism is to provide a carrier for cold and heat transfer for the combined cold and hot supply mechanism, and simultaneously solve the problem of energy and time mismatch when the self-service cabinet is in use; the purpose of setting up a sterilization and disinfection mechanism is to disinfect and sterilize the self-service cabinet body during idle periods to ensure the hygiene and safety of the items stored in the self-service cabinet. The heat exchange partitions are arranged horizontally inside the self-service cabinet body and adopt contact heat exchange. Compared with the traditional forced convection heat exchange system, it greatly reduces the dry loss of fresh food and improves the quality of the goods. The self-service cabinet body includes a refrigerated cabinet body and a hot cabinet body, which are used to meet the different storage needs of fresh food and boxed lunches respectively.

[0006] Furthermore, the combined cooling and heating mechanism includes a heat pump unit, an air heat exchanger, a temperature sensor, and a controller. The condenser end of the heat pump unit is connected to the hot cabinet body pipe, and the evaporator end of the heat pump unit is connected to the cold cabinet body pipe. The heat pump unit provides heat to the hot cabinet body through the condenser and provides cooling to the cold cabinet body through the evaporator. The air heat exchanger is located on one side of the heat pump unit, connected to the heat pump unit pipe, and the other end of the air heat exchanger is electrically connected to the controller. The purpose of setting up the air heat exchanger is to discharge the excess cooling or heat generated by the heat pump unit through the air heat exchanger when the cold and hot temperatures in winter and summer are mismatched, so as to ensure that the heat pump unit is not affected by the environment and operates normally. The end of the controller away from the air heat exchanger is electrically connected to the temperature sensor, and the temperature sensors are respectively arranged on the inner wall of the self-service cabinet body. The temperature sensor is set to detect the internal temperature of the self-service cabinet body, thereby transmitting commands to the controller, and the controller controls the air heat exchanger to achieve its function.

[0007] Furthermore, the heat-carrying and cold-carrying circulation mechanism includes a heat-carrying pipe, a cold-carrying pipe, a pipeline valve, and a heat-storage and cold-storage mechanism. The heat-carrying pipe is installed on the inner wall of the hot cabinet, and the cold-carrying pipe is installed on the inner wall of the cold cabinet. The heat-carrying pipe and the cold-carrying pipe are provided with multiple pipeline valves, and the two ends of the heat-carrying pipe and the cold-carrying pipe are respectively connected to the heat-storage and cold-storage mechanism. The heat-carrying pipe and the cold-carrying pipe are respectively provided with a heat carrier and a cold carrier, which can transfer heat and cold to every corner of the self-pickup cabinet and realize a circulation system. The heat-storage and cold-storage mechanism is provided on both sides of the heat pump unit, and the heat-storage and cold-storage mechanism is connected to the heat pump unit through a pipeline. The purpose of setting up the heat-storage and cold-storage mechanism is to solve the problem of energy and time mismatch when the self-pickup cabinet is used; if there is a valley electricity price policy in the use scenario, the energy storage technology can further save operating costs.

[0008] Furthermore, the heat storage and cold storage mechanism includes a heat storage tank, a cold storage tank, a water pump, a valve and a plate heat exchanger. One end of the heat storage tank and the cold storage tank is connected to the heat pump unit respectively, and the other end of the heat storage tank and the cold storage tank is connected to the water pump respectively. By utilizing the action of the water pump and water as a medium, the heat storage and cold storage functions of the heat storage tank and the cold storage tank are realized, which greatly saves operating costs. The plate heat exchanger is arranged between the heat storage tank, the cold storage tank and the heat pump unit to achieve efficient heat exchange. The valve is arranged between the heat storage tank, the cold storage tank and the water pump, and the heat storage tank, the cold storage tank, the water pump, the valve, the plate heat exchanger and the heat pump unit are all connected by pipes.

[0009] Furthermore, an auxiliary heater is provided inside the heat storage tank, which is electrically connected to the heat pump unit. The purpose of the auxiliary heater is to ensure the normal operation of the heat pump unit under severe winter and extreme low temperature weather conditions in high-latitude areas.

[0010] Furthermore, the sterilization and disinfection mechanism includes a nozzle, a pressure vessel, and a liquid storage box. The nozzles are located on the inner wall of the self-service cabinet. One end of the pressure vessel is connected to the nozzles, and the other end is connected to the liquid storage box, which is located on the outer wall of the self-service cabinet. Under the action of the pressure vessel, the disinfectant in the liquid storage box is evenly sprayed into the cabinet through the nozzles, achieving the disinfection and sterilization effect, thereby ensuring the sanitation and safety of the internal environment of the self-service cabinet.

[0011] Furthermore, the heat exchange baffle comprises three layers, with the upper and lower layers arranged in parallel, and the middle layer of the heat exchange baffle being in a W-shaped wave shape. The three-layer arrangement of the heat exchange baffle is intended to: first, utilize contact heat exchange, which significantly reduces the dryness loss of fresh food and improves product quality compared to traditional forced convection heat exchange systems; second, ensure that heat is evenly diffused and distributed, preventing localized excessive heat from causing uneven heating of the heat exchange baffle and causing damage; and third, eliminate the phenomenon of hot and cold air convection circulation, which can solve the problem of odor transfer between foods and reduce heat loss.

[0012] Furthermore, an anti-condensation interlayer is provided in the middle of the heat exchange baffle, a guide tube is provided between the anti-condensation interlayer, and a number of one-way small holes are provided in the anti-condensation interlayer. A ventilation port is provided at the junction of the heat exchange baffle and the inner wall of the self-service cabinet. The pressure difference generated by the heat exchange within the heat insulation board provides suction, sucking condensation into the interlayer through the one-way small holes and discharging it outward through the guide tube, thereby achieving anti-drip condensation measures. As the condensation is discharged, the internal hot air also decreases, and new air is then added through the ventilation port to achieve air flow within the heat exchange baffle, further achieving heat diffusion and uniform distribution.

[0013] Furthermore, the heat exchange baffle is made of a copper-aluminum alloy. Copper has a much faster thermal conductivity than aluminum, but it does not dissipate heat as quickly as aluminum and is prone to oxidation. Therefore, by combining copper and aluminum through a certain process, the copper can quickly transfer heat to the aluminum, and then the large area of ​​aluminum can dissipate the heat.

[0014] Furthermore, the inner wall of the self-pickup cabinet includes three layers, the middle layer of the self-pickup cabinet body is connected, and the inner and outer layers of the self-pickup cabinet body are constructed of thermal insulation materials, so that the self-pickup cabinet can be converted into an insulated express cabinet when there is no need to use it.

[0015] Compared with the existing technology, the present invention achieves the following beneficial effects: 1. In the present invention's cold and heat storage combined heat and cold supply self-service cabinet, the heat pump unit provides heat to the hot cabinet body through the condenser and provides cooling to the cold cabinet body through the evaporator. An air heat exchanger is also provided. When the heat and cold temperatures are mismatched in winter and summer, excess cooling or heat generated by the heat pump unit can be discharged through the air heat exchanger, ensuring that the heat pump unit is not affected by the environment and operates normally.

[0016] 2. The present invention provides a cold storage and heat storage combined heat and cold supply self-service cabinet. The heat and cold circulation mechanism provides a carrier for cold and heat transfer for the combined heat and cold supply mechanism, and utilizes the heat storage and cold storage mechanism to simultaneously solve the problem of energy and time mismatch when the self-service cabinet is used.

[0017] 3. The cold and heat storage type cold and heat supply self-service cabinet of the present invention has a sterilization and disinfection mechanism that can disinfect the cabinet body during idle time periods to ensure the hygiene and safety of the items stored in the self-service cabinet.

[0018] 4. The cold storage and heat storage type cold and heat supply self-pickup cabinet of the present invention has a heat exchange partition including three layers. The purpose of setting them is: first, it adopts contact heat exchange, which greatly reduces the dry loss of fresh food and improves the quality of goods compared with the traditional forced convection heat exchange system; second, it makes the heat diffuse and distribute evenly to prevent local excessive heat, which causes uneven heating of the heat exchange partition and causes damage; third, there will be no phenomenon of cold and hot air convection circulation, which can solve the problem of flavor transfer between foods and at the same time reduce heat loss.

[0019] 5. This cold and heat storage combined heat and cold supply self-service cabinet features a central anti-condensation interlayer. This prevents condensation by utilizing the pressure differential generated by heat exchange within the insulation panels to expel condensation, thereby preventing dripping and condensation. As condensation is expelled, the internal hot air decreases, and new air is then introduced through the ventilation ports, promoting air flow within the heat exchange panels and further achieving heat diffusion and uniform distribution.

[0020] 6. The heat storage and cold storage type combined heat and cold supply self-service cabinet of the present invention has a heat exchange partition made of copper-aluminum alloy. The thermal conductivity of copper is much faster than that of aluminum, but the heat dissipation of copper is not as fast as that of aluminum, and copper is prone to oxidation. Therefore, copper and aluminum are combined through a certain process, which allows copper to quickly transfer heat to aluminum, and then the heat is dissipated by a large area of ​​aluminum.
