[0030] The utility model provides an unmanned takeaway delivery device.

[0031] In the embodiment of the present utility model, Figures 1 to 3 As shown, the unmanned takeaway delivery device includes a cabinet 10, a heating element 20 and a refrigeration element 30;

[0032] The cabinet 10 includes a normal temperature zone 101, a heat preservation zone 102 and a refrigeration zone 103, each of the normal temperature zone 101, the heat preservation zone 102 and the refrigeration zone 103 has a plurality of storage cavities 104, and a vacuum layer is provided between any two adjacent zones among the normal temperature zone 101, the heat preservation zone 102 and the refrigeration zone 103;

[0033] The heating element 20 is disposed on the cabinet 10 and is thermally connected to the cavity wall of each storage cavity 104 in the heat preservation area 102. The heating element 20 is used to heat the storage cavity 104 in the heat preservation area 102.

[0034] The refrigeration element 30 is disposed on the cabinet 10 and is thermally connected to the cavity wall of each storage cavity 104 in the refrigeration area 103 . The refrigeration element 30 is used to cool the storage cavity 104 in the refrigeration area 103 .

[0035] Specifically, the cabinet 10 is the main structure of the entire device, which is divided into three different areas: a normal temperature area 101, a heat preservation area 102 and a refrigerated area 103. These three areas are used to store foods with different temperature requirements. Each area contains a plurality of storage cavities 104, which are independent spaces for placing take-out foods. It is worth noting that a vacuum layer is provided between any two adjacent temperature zones. The function of the vacuum layer is heat insulation, which can effectively prevent heat exchange between different temperature zones and ensure that each area can maintain its required temperature.

[0036] In specific implementation, the vacuum layer can be implemented in a variety of ways. One common implementation method is to set a double-wall structure between adjacent temperature zones and evacuate the air between the double walls to form a vacuum. Another method is to use a vacuum insulation panel, which has a vacuum state inside and can be directly installed between temperature zones. The thickness of the vacuum layer can be adjusted according to actual needs, usually between 5-20mm.

[0037] The heating element 20 can be in various forms such as electric heating wire, heating film or PTC heating element. Among them, the heating film is suitable for application in the device because of its thin thickness and uniform heating. The refrigeration element 30 can use a traditional compressor refrigeration system or a semiconductor refrigeration sheet. The heat conduction connection refers to the heat transfer method between the heating element 20 and the refrigeration element 30 and the wall of the storage cavity 104. This connection can be achieved by direct contact or by a heat conductive material (such as an aluminum plate or a copper plate). In order to improve the efficiency of heat conduction, thermal conductive silicone grease can also be applied to the contact surface. This design ensures that the heating and cooling effects can be quickly and evenly transferred to the storage cavity 104. Through the comprehensive use of these technical means, the unmanned takeaway delivery device realizes accurate temperature control and efficient storage of different types of food, effectively solves the problems of single storage environment and inaccurate temperature control of existing takeaway cabinets, greatly improves the food preservation quality and energy utilization efficiency, and provides users with a better quality and safer takeaway storage solution.

[0038] In some embodiments, the cabinet 10 includes a left side plate 105 and a right side plate 106 that are spaced and arranged opposite to each other in the width direction thereof, and a top partition 107, a first middle partition 108, a second middle partition 109 and a bottom partition 110 that are arranged between the left side plate 105 and the right side plate 106. The top partition 107, the first middle partition 108, the second middle partition 109 and the bottom partition 110 are spaced from top to bottom in the height direction of the cabinet 10. The normal temperature zone 101 is formed between the top partition 107 and the first middle partition 108, the heat preservation zone 102 is formed between the first middle partition 108 and the second middle partition 109, and the refrigeration zone 103 is formed between the second middle partition 109 and the bottom partition 110.

[0039] The vacuum layer is disposed inside the first intermediate partition plate 108 and inside the second intermediate partition plate 109 .

[0040] Specifically, the left side plate 105 and the right side plate 106 constitute the two side walls of the cabinet 10. Between the left side plate 105 and the right side plate 106, a top partition 107, a first middle partition 108, a second middle partition 109 and a bottom partition 110 are sequentially arranged from top to bottom. These partitions and the two side plates together form the basic frame structure of the entire cabinet 10.

[0041] This design divides the internal space of the cabinet 10 into three main areas: the normal temperature zone 101 is located between the top partition 107 and the first middle partition 108, the heat preservation zone 102 is located between the first middle partition 108 and the second middle partition 109, and the refrigerated zone 103 is located between the second middle partition 109 and the bottom partition 110. The refrigerated zone 103 is set at the bottom and is mainly used to store fruits, cakes and other foods that need to be stored at low temperatures. Fruits are usually heavy, and placing them at the bottom can lower the center of gravity and improve the stability of the entire cabinet 10. Secondly, placing fragile foods such as cakes at the bottom can reduce shaking during transportation and reduce the risk of damage. In addition, the density of cold air is relatively large, and its natural sinking characteristics make it more conducive to uniform distribution and maintenance of temperature to place the refrigerated zone 103 at the bottom.

[0042] The heat preservation area 102 is located in the middle of the cabinet 10 and is mainly used to store daily hot takeout food, such as lunch and dinner. This position design is based on ergonomic considerations. The elbow height of most adults is between 90-110 cm. Setting the heat preservation area 102 within this height range allows users to maintain the most comfortable posture when taking and placing food, reducing the discomfort of bending or stretching. This not only improves the convenience of use, but also reduces the risk of burns, because users can easily observe the status of food at eye level.

[0043] The normal temperature zone 101 is arranged at the top, and is suitable for storing foods that do not require special temperature control, such as bread and snacks. These foods are usually light, and placing them at the top will not increase the instability of the cabinet 10.

[0044] The design of the present application is not limited to the above structure. In some embodiments, other partitions may be provided between adjacent partitions (such as between the top partition 107 and the first middle partition 108) to facilitate dividing the space into more cavities as needed.

[0045] In some embodiments, the cabinet 10 includes a rear baffle 111, the rear baffle 111 is respectively connected to the left side plate 105, the top partition 107, the first middle partition 108, the second middle partition 109, the bottom partition 110 and the right side plate 106, and the rear baffle 111 has a first heat conduction wall located between the first middle partition 108 and the second middle partition 109, and a second heat conduction wall located between the second middle partition 109 and the bottom partition 110;

[0046] A first cavity 111a and a second cavity 111b independent of each other are formed in the rear baffle 111, the first heat conduction wall forms a partial cavity wall of the first cavity 111a, the second heat conduction wall forms a partial cavity wall of the second cavity 111b, the heating element 20 is disposed in the first cavity 111a, and the refrigeration element 30 is disposed in the second cavity 111b.

[0047] Specifically, the specific implementation of this design can have many variations. For example, the first cavity 111a and the second cavity 111b can be of different shapes and sizes to accommodate different models of heating elements 20 and cooling elements 30. The heat conduction wall can be made of high thermal conductivity materials such as aluminum or copper to improve the heat conduction efficiency. The cavity can be filled with a heat conducting medium, such as thermal grease or thermal gel, to further enhance the heat conduction effect.

[0048] In some embodiments, the first cavity 111a and the second cavity 111b can be designed to be detachable to facilitate maintenance and replacement of the internal heating element 20 and cooling element 30. In addition, a temperature sensor can be set in the cavity to monitor the temperature change in the cavity in real time and provide data support for precise temperature control.

[0049] The design of the rear baffle 111 has many advantages. First, it realizes the centralized management of the heating and cooling systems, which is convenient for installation and maintenance. Second, by isolating the heating element 20 and the cooling element 30 from the storage area, the risk of direct contact with food is avoided, thereby improving food safety. Finally, the heating and cooling systems are concentrated in the rear baffle 111, which effectively utilizes the space of the cabinet 10, leaving more space for the storage area in the front, thereby improving storage efficiency.

[0050] It should be noted that the rear baffle 111 of the present application includes a baffle body and a surrounding plate. The baffle body is respectively connected to the left plate 105, the top partition 107, the first middle partition 108, the second middle partition 109, the bottom partition 110 and the right plate 106. A first heat conduction wall and a second heat conduction wall are formed on the baffle body. The side of the baffle body facing away from the first middle partition 108 is connected to the surrounding plate. The shape of the surrounding plate can be set as needed. The function of the surrounding plate is mainly to cooperate with the baffle body to define the first cavity 111a and the second cavity 111b.

[0051] In some embodiments, a cavity wall of the second cavity 111b is formed with a take-in / put-out opening, and the cavity wall of the second cavity 111b is further provided with a cover 111c that can movably cover the take-in / put-out opening;

[0052] The refrigeration component 30 is an ice-water mixture, and the refrigeration component 30 enters and exits the second cavity 111 b through the access port.

[0053] Specifically, the design purpose of the access opening is to facilitate the replacement and maintenance of the refrigeration component 30. A movable cover 111c is also provided on the wall of the second cavity 111b to cover the access opening. This design not only ensures the sealing of the refrigeration system, but also provides a convenient operation method.

[0054] The cover body 111c can be designed in various forms. For example, it can be a simple sliding cover connected to the cavity wall through a slide rail, or it can be a hinged cover connected to the cavity wall through a hinge.

[0055] Using ice-water mixture as the refrigeration element 30 is a simple and effective refrigeration method. The ice-water mixture has good heat capacity and can maintain a stable low temperature for a long time. The ice-water mixture is low in cost and easy to obtain; secondly, it does not require complex refrigeration equipment, reducing the complexity and failure rate of the device; finally, it is an environmentally friendly refrigeration method and will not cause harmful refrigerant leakage problems.

[0056] In a specific implementation, a detachable container may be provided in the second cavity 111b for containing the ice-water mixture, so that the replacement operation can be performed more conveniently.

[0057] In some embodiments, the bottom wall of the second cavity 111b is inclined, and the height of the side edge of the bottom wall of the second cavity 111b close to the second heat conduction wall is lower than the height of the side edge of the bottom wall of the second cavity 111b away from the second heat conduction wall.

[0058] Specifically, this tilted design takes advantage of the fluidity of water and the sinking characteristics of cold air. As the ice in the ice-water mixture gradually melts, the cold water will naturally flow to the lower side of the bottom, that is, the side close to the second heat conduction wall. This ensures that the cold water always maintains maximum contact with the heat conduction wall, improving the heat exchange efficiency. At the same time, due to the high density of cold air, it will naturally sink to the lower side of the bottom, further enhancing the cooling effect. Secondly, this design facilitates the replacement and cleaning of the ice-water mixture. When the refrigerant needs to be replaced, the melted water will naturally gather on the lower side of the bottom for easy discharge. Similarly, during cleaning and maintenance, it is also easier to remove residual moisture and impurities.

[0059] In some embodiments, the heating element 20 is a heating film, and the heating film is attached to the surface of the first heat conduction wall.

[0060] Specifically, the heating film is a thin and flexible heating element made of a conductive material (such as carbon fiber or metal alloy) embedded in an insulating material (such as polyimide). Its working principle is to use the heat generated when an electric current passes through it to heat the surrounding environment.

[0061] The heating film has an extremely thin thickness, usually only a few millimeters or even thinner. This feature allows it to fit tightly on the surface of the first heat-conducting wall without taking up additional space, and the heating film can provide uniform heat distribution. Since it can cover the entire surface of the heat-conducting wall, heat can be transferred more evenly to every corner of the insulation zone 102, avoiding the problem of local overheating or uneven temperature. The heating film has a fast response speed and heats up quickly. When the power is turned on, it can reach the preset temperature in a short time, which is very important for maintaining the temperature of food, especially when the insulation zone 102 door is frequently opened and closed.

[0062] The specific implementation of the heating film can be varied in many ways. For example, heating films of different powers can be selected to meet different heating requirements. The heating film can be cut into a specific shape to fully match the size and shape of the first heat-conducting wall. During installation, thermally conductive glue or thermally conductive silicone grease can be used to enhance the heat conduction effect between the heating film and the heat-conducting wall.

[0063] In some embodiments, a plurality of vertical partition plates 112 are provided in the normal temperature zone 101, and the plurality of vertical partition plates 112 are spaced apart in the width direction of the cabinet 10 to divide the normal temperature zone 101 into a plurality of storage chambers 104; wherein,

[0064] The plate body of the left plate 105 located in the normal temperature zone 101 , each of the vertical partition plates 112 , and the plate body of the right plate 106 located in the normal temperature zone 101 are all provided with air outlets 113 .

[0065] Furthermore, the structure on the left side plate 105 corresponding to the normal temperature zone 101 , the structure on the right side plate 106 corresponding to the normal temperature zone 101 , and the structure on the rear baffle plate 111 corresponding to the normal temperature zone 101 are also provided with air outlets 113 .

[0066] The purpose of this design is to ensure good air circulation in the normal temperature zone 101. Good air circulation can prevent local moisture or odor in the normal temperature zone 101. This is especially important for storing foods such as bread and snacks that do not require special temperature control but need to be kept dry.

[0067] The air vent 113 can be designed in different shapes and sizes, such as round, long strip or grid, to meet different ventilation requirements. The air vent 113 can be designed to be adjustable, allowing the user to adjust the ventilation volume as needed. In some embodiments, a dustproof net or filter membrane can be installed at the air vent 113 to prevent dust and foreign matter from entering the storage cavity 104.

[0068] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
