Description

Technical Field

[0001] This utility model relates to a refrigerated vending machine with a heating function, and belongs to the technical field of refrigerated vending machines. Background Technology

[0002] Currently, with the accelerating pace of life and diversified consumer demands, vending machines are becoming increasingly widely used in daily life. Traditional refrigerated vending machines are mainly used to sell various refrigerated foods and beverages, providing consumers with chilled goods to meet their needs for fresh and chilled food. However, in some scenarios, consumers also have a need to purchase heated food, such as hot drinks or heated lunches in cold weather.

[0003] While some existing vending machines have attempted to add heating functions, most simply incorporate heating devices into ordinary vending machines, resulting in numerous shortcomings. For example, a utility model patent from Taiwan, patent application number TW113205222, discloses a vending machine capable of sensing the degree of frost buildup. By adding a heating device to the vending machine, it allows customers to heat their food when needed, thus effectively meeting customer demands. However, it presents certain problems in practical use:

[0004] The aforementioned heating device generates a significant amount of heat during the heating process. If this heat is not effectively isolated and managed, it will rapidly transfer to the refrigerated area of ​​the vending machine, causing the ambient temperature to rise. To maintain the low temperature in the refrigerated area, the refrigeration system needs to continuously increase its power, which not only increases energy consumption and operating costs but also accelerates the wear and tear on the refrigeration equipment, shortening its lifespan. Furthermore, the addition of the heating function did not adequately consider the noise and electromagnetic interference generated by the heating device. The noise and electromagnetic radiation generated during operation may interfere with the electronic components within the refrigeration system, leading to malfunctions in the vending machine and consequently affecting its normal sales and operation. Utility Model Content

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] Example: Please refer to Figures 1-3 This embodiment provides a refrigerated vending machine with a heating function, including a vending machine body 1 with a refrigeration system. A heating chamber 2 is located on the right side of the vending machine body 1, and the heating chamber 2 is fixedly connected to the vending machine body 1. A heating device 3 is embedded in the front side wall of the heating chamber 2, and an installation chamber 4 is provided inside the heating chamber 2, with the heating device 3 located within the installation chamber 4. In this embodiment, the heating device 3 is specifically a microwave oven. The microwave oven door and operating end are located outside the front side wall of the heating chamber 2, allowing consumers to open the microwave oven door to place food and perform heating operations using the operating end. An isolation structure 5 is provided on the side wall of the installation chamber 4 close to the vending machine body 1, covering the side wall of the installation chamber 4 close to the vending machine body 1. To improve the isolation effect of the isolation structure 5, the isolation structure 5 also covers the top and bottom inner walls of the installation chamber 4. The isolation structure 5 can isolate the heat, noise and electromagnetic radiation generated by the heating device 3 to ensure that the refrigeration system of the vending machine body 1 is free from the influence of the heating device 3.

[0023] In this embodiment, the isolation structure 5 includes a first heat insulation layer 51, a second heat insulation layer 54, an electromagnetic shielding layer 52, and a sound insulation layer 53. Among them, both the first heat insulation layer 51 and the second heat insulation layer 54 are arranged in a "匚"-shaped structure. The top section structure and the bottom section structure of the first heat insulation layer 51 are respectively bonded to the top inner wall and the bottom inner wall of the installation chamber 4. The top section structure and the bottom section structure of the second heat insulation layer 54 are respectively bonded to the top section structure and the bottom section structure of the first heat insulation layer 51. The electromagnetic shielding layer 52 and the sound insulation layer 53 are arranged between the middle section structure of the first heat insulation layer 51 and the middle section structure of the second heat insulation layer 54. The distribution direction of the material layers at the middle position of the isolation structure 5 is specifically in the direction close to the heating device 3, which are successively the middle section structure of the first heat insulation layer 51, the electromagnetic shielding layer 52, the sound insulation layer 53, and the middle section structure of the second heat insulation layer 54. The middle section structure of the first heat insulation layer 51, the electromagnetic shielding layer 52, the sound insulation layer 53, and the middle section structure of the second heat insulation layer 54 are bonded together in sequence.

[0024] In this embodiment, the first heat insulation layer 51 is a polyurethane foam layer, that is, a composite board structure made of polyurethane foam, which has excellent heat insulation performance and low thermal conductivity, so as to effectively prevent heat from being transferred to the vending machine body 1. The electromagnetic shielding layer 52 is a metal mesh layer, which can be a copper metal mesh, an aluminum metal mesh, a stainless steel metal mesh, etc. The electromagnetic shielding layer 52 can effectively block the propagation of electromagnetic waves, so as to play a role in shielding the electromagnetic radiation generated by the heating device 3 and preventing it from being transmitted to the vending machine body 1. The sound insulation layer 53 is a polyester fiber layer, that is, a material layer structure made of polyester fiber material, which can effectively absorb sound waves, so as to avoid the situation that the noise generated by the operation of the heating device 3 interferes with the electronic components inside the vending machine body 1. The second heat insulation layer 54 is a metal plate layer with a hollow interior. The specific metal material can be a high emissivity metal material such as aluminum or stainless steel. The high reflectivity metal can reflect the thermal radiation generated by the operation of the heating device 3 to reduce the heat transfer to the vending machine body 1. The hollow interior structure uses the air layer to block the heat conduction, so as to further block the heat from being transferred to the vending machine body 1. Based on the above-set isolation structure 5, it combines the functions of heat insulation, sound insulation, and electromagnetic radiation shielding, so as to ensure that the vending machine body 1 will not be affected by the operation of the heating device 3. In actual use, the specific thickness settings of the first heat insulation layer 51, the electromagnetic shielding layer 52, the sound insulation layer 53, and the second heat insulation layer 54 can be selected according to the actual situation. The following provides corresponding preferred settings: the thickness of the first heat insulation layer 51 is preferably 50 - 100 mm, the diameter of the metal wire of the electromagnetic shielding layer 52 is preferably 0.2 - 1 mm, the mesh size is preferably 1 - 5 mm, and the thickness is preferably 2 - 5 mm. The thickness of the sound insulation layer 53 is preferably 20 - 50 mm, the metal thickness of the second heat insulation layer 54 is 1 - 3 mm, and the thickness of the hollow part is 10 - 30 mm.

[0025] To further ensure heat dissipation, in this embodiment, a cooling fan 6 is also installed inside the mounting chamber 4, and the cooling fan 6 is fixedly installed on the bottom section of the second heat insulation layer 54. The blowing end of the cooling fan 6 is oriented towards the heating device 3 so that it can generate airflow to the heating device 3 for heat dissipation when it is working. An air inlet 7 communicating with the mounting chamber 4 is provided on the front side wall of the heating box 2, and an air outlet 8 communicating with the mounting chamber 4 is provided on the side wall of the heating box 2 away from the vending machine body 1. With the aforementioned arrangement, when the cooling fan 6 starts working, it can draw in cooler external air from the air inlet 7 and blow it towards the heating device 3 to remove the heat generated by the heating device 3. The hot air will be discharged from the air outlet 8. To reduce energy consumption, in actual use, a temperature sensor can be installed on the outer side wall of the heating device 3 to detect the overall temperature of the heating device 3, and the temperature sensor can be electrically connected to the cooling fan 6. When the temperature sensor detects that the temperature of the heating device 3 has risen to its set threshold due to prolonged operation, the temperature sensor generates an electrical signal to control the cooling fan 6 to work, so as to dissipate heat from the heating device 3, thereby ensuring the heat dissipation effect and extending the service life of the heating device 3.
