Description

Technical Field

[0001] This utility model relates to the field of unmanned vending machine technology, specifically a double-door unmanned vending machine with defogging function. Background Technology

[0002] The dual-door unmanned vending machine is an intelligent retail solution. Its structure includes a vertical device with two independent doors, and is equipped with shelves, sensors, billing systems and other components. Customers select goods themselves through a touch screen or mobile application, and after completing payment, the electronic lock opens the corresponding door to realize unmanned vending. The system monitors the equipment status and inventory level in real time through the control system, and has the ability to remotely update product information.

[0003] An existing patent (publication number: CN215576776U) discloses a double-door unmanned vending machine, including a cabinet body. One side of the cabinet body has two doors, and the doors have operation panels. The other side of the cabinet body has a dehumidification box. The top of the dehumidification box has an air inlet pipe, and the air inlet pipe has an air fan. The dehumidification box has a dehumidification chamber inside, and a storage frame is provided on the dehumidification chamber. The storage frame has a drying bag and a purification bag. The cabinet body has a cavity inside, and the cavity has a shelf and a humidity detection mechanism.

[0004] Although the aforementioned patent allows the materials from the drying and purification bags to slowly enter the air cavity by closing the first solenoid valve on the air inlet pipe and opening the first solenoid valve on the air outlet pipe, thus drying and purifying the air in the cavity, fogging occurs on the glass of the cabinet door during the opening and closing process, especially on the inner side of the door. The temperature difference generated by opening and closing the door causes water vapor in the air to condense into water droplets on the glass surface, which reduces the visibility of the goods inside the cabinet and affects their clear observation and selection of the goods. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a double-door unmanned vending machine with defogging function, which has the advantage of automatic and stable defogging during use, thus solving the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a double-door unmanned vending machine with defogging function, comprising a cabinet body and a cabinet door assembly installed on the front of the cabinet body. The cabinet body is provided with a load-bearing assembly and an auxiliary assembly. The cabinet door assembly includes an outer frame, which is connected to the cabinet body by a hinge. The inner wall of the outer frame is fixed with double-layer tempered glass. A thin-film heating wire is provided inside the double-layer tempered glass. The material of the thin-film heating wire is indium tin oxide, and the thin-film heating wire is evenly distributed on the inner surface of the double-layer glass.

[0007] Furthermore, the supporting component includes multiple sets of supporting plates fixed to the inner wall of the cabinet. The upper surface of the supporting plate is provided with a corresponding supporting groove. The supporting groove is slidably connected to the supporting plate, and a partition plate is fixed to the inner wall of the supporting groove.

[0008] The above solution allows the carrier groove to be pulled out during replenishment operations through the sliding connection between the carrier groove and the carrier plate, facilitating the replenishment process.

[0009] Furthermore, a bearing block corresponding to the bearing groove is fixed on the upper surface of the bearing plate, the bearing groove is slidably connected to the bearing block, and notches are opened on the sides of the two sets of bearing blocks located on the inner side, and a corresponding baffle is fixed on the side of the bearing groove.

[0010] With the above solution, when the bearing groove is pulled out, the baffle can be blocked by the outermost bearing block through the inner bearing block, thus preventing the bearing groove from being pulled out directly due to excessive pulling.

[0011] Furthermore, a cavity is formed on the inner side of the outermost bearing block, and a limiting block is slidably connected to the inner wall of the cavity formed by the bearing block. A corresponding limiting groove is formed on the side of the bearing groove, and the limiting block is engaged with the limiting groove.

[0012] The above solution maintains the stability of the bearing groove in the storage state by engaging the limiting block with the limiting groove.

[0013] Furthermore, a reset spring and a reset telescopic rod are provided inside the cavity of the bearing block. One end of the reset spring and the reset telescopic rod are fixed to the limiting block, and the other end of the reset spring and the reset telescopic rod are fixed to the bearing block.

[0014] The above method allows the limit block to be reset by the elastic force of the reset spring.

[0015] Furthermore, the auxiliary components include two sets of air pumps installed on the top and bottom walls of the cabinet, and multiple nozzles are installed at the output end of the air pumps, with the nozzles aimed at the cabinet door assembly.

[0016] The above method involves heating the cabinet using a thin-film heating wire, then using an air pump to extract gas from inside the cabinet and spray it onto the surface of the cabinet door assembly, helping the temperature of the cabinet door assembly to return to the same state as the inside of the cabinet.

[0017] Furthermore, the inner wall edge of the cabinet is provided with a rubber sealing strip, and the outer frame is in contact with the rubber sealing strip.

[0018] The above solution is used to enhance the sealing performance of the cabinet door when it is closed.

[0019] Furthermore, an electromagnetic lock is installed on the cabinet, a temperature and humidity sensor is installed on the inner side of the double-layered tempered glass, the temperature and humidity sensor is connected to the controller signal, and an intelligent monitoring device is installed on the inner top wall of the cabinet.

[0020] The above method uses temperature and humidity sensors to determine whether the thin-film heating wire and air pump are turned on.

[0021] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0022] This type of double-door unmanned vending machine with defogging function uses a door assembly to heat the double-layer tempered glass with a thin-film heating wire when the door is opened or closed, removing water vapor adhering to the surface of the double-layer tempered glass. The transparency of the indium tin oxide film has almost no impact on the consumer's vision, ensuring the complete display of goods. An air pump draws gas from inside the cabinet and sprays it onto the surface of the door assembly, helping the temperature of the door assembly to return to the same state as the inside of the cabinet. The cooperation of temperature sensors and controllers enables automatic control of the heating wire, avoiding unnecessary energy consumption and reducing operating costs.

[0035] Please see Figure 1 , Figure 2 and Figure 3 This embodiment of a double-door unmanned vending machine with defogging function includes a cabinet body 1 and a cabinet door assembly 2 installed on the front of the cabinet body 1. The cabinet body 1 is provided with a load-bearing assembly 3 and an auxiliary assembly 4. The cabinet door assembly 2 includes an outer frame 201, which is connected to the cabinet body 1 by a hinge. The inner wall of the outer frame 201 is fixed with double-layer tempered glass 202. The double-layer tempered glass 202 is provided with a thin-film heating wire 203 inside. The thin-film heating wire 203 is made of indium tin oxide and is evenly distributed on the inner surface of the double-layer glass.

[0036] Please see Figure 3 , Figure 4 and Figure 5 The supporting component 3 includes multiple sets of supporting plates 301 fixed to the inner wall of the cabinet 1. The upper surface of the supporting plate 301 is provided with a corresponding supporting groove 302. The supporting groove 302 is slidably connected to the supporting plate 301. The inner wall of the supporting groove 302 is fixed with a partition plate 303. The supporting groove 302 can be pulled out during replenishment operations due to the slidable connection between the supporting groove 302 and the supporting plate 301, which facilitates replenishment operations. The upper surface of the supporting plate 301 is fixed with a supporting block 304 corresponding to the supporting groove 302. The supporting groove 302 is slidably connected to the supporting block 304. The two sets of supporting blocks 304 on the inner side have notches on their sides. The side of the supporting groove 302 is fixed with a corresponding baffle 305. When the supporting groove 302 is pulled out, the baffle 305 can be blocked by the outermost supporting block 304 through the inner supporting block 304, which prevents the supporting groove 302 from being pulled out directly due to excessive pulling.

[0037] Please see Figure 3 , Figure 4 and Figure 5The inner side of the outermost support block 304 has a cavity. The inner wall of the cavity of the support block 304 is slidably connected to a limiting block 306. The side of the support groove 302 has a corresponding limiting groove. The limiting block 306 is engaged with the limiting groove. The engagement of the limiting block 306 with the limiting groove maintains the stability of the support groove 302 in the storage state. The cavity of the support block 304 is provided with a reset spring 307 and a reset telescopic rod 308. One end of the reset spring 307 and the reset telescopic rod 308 is fixed to the limiting block 306, and the other end of the reset spring 307 and the reset telescopic rod 308 is fixed to the support block 304. The elastic force of the reset spring 307 can push the limiting block 306 to reset.

[0038] Please see Figure 3 , Figure 4 and Figure 5 The auxiliary component 4 includes two sets of air pumps 401 installed on the top and bottom walls of the cabinet 1. Multiple nozzles 402 are installed at the output end of the air pumps 401. The nozzles 402 are aimed at the cabinet door assembly 2. After heating by the thin-film heating wire 203, the air pumps 401 draw gas from inside the cabinet 1 and spray it onto the surface of the cabinet door assembly 2, helping the temperature of the cabinet door assembly 2 to return to the same state as inside the cabinet 1. A rubber sealing strip 5 is provided on the inner edge of the cabinet 1. The outer frame 201 contacts the rubber sealing strip 5 to enhance the sealing performance when the cabinet door is closed. An electromagnetic lock is installed on the cabinet 1. A temperature and humidity sensor 6 is installed on the inner side of the double-layer tempered glass 202. The temperature and humidity sensor 6 is connected to the controller signal. An intelligent monitoring device 7 is installed on the inner top wall of the cabinet 1. The temperature and humidity sensor 6 is used to determine whether the thin-film heating wire 203 and the air pumps 401 are turned on.

[0039] This embodiment of a double-door unmanned vending machine with defogging function, by setting up a cabinet door assembly 2, heats the double-layer tempered glass 202 through a thin-film heating wire 203 when the cabinet door is opened and closed, removing the water mist adhering to the surface of the double-layer tempered glass 202. The transparency of the indium tin oxide film hardly affects the consumer's vision, ensuring the complete display of the goods. An air pump 401 draws gas from inside the cabinet body 1 and sprays it onto the surface of the cabinet door assembly 2, helping the temperature of the cabinet door assembly 2 to return to the same state as the inside of the cabinet body 1. The cooperation of the temperature sensor and controller realizes the automatic control of the heating wire, avoiding unnecessary energy consumption and reducing operating costs.

[0040] It should be noted that during use, a temperature sensor is installed on the glass surface to monitor the glass temperature in real time. The controller is connected to the thin-film heating wire 203 and the air pump 401. Based on the information fed back by the temperature sensor, the controller automatically controls the working state of the thin-film heating wire 203 and the air pump 401. When the glass temperature is lower than the set value, the controller starts the heating wire to heat the glass; when the glass temperature reaches the set value, the controller stops the heating wire from working.

[0041] The working principle of the above embodiment is as follows: When opening and closing the cabinet door, the double-layer tempered glass 202 is heated by the thin-film heating wire 203 to remove the water mist adhering to the surface of the double-layer tempered glass 202. The transparency of the indium tin oxide film hardly affects the consumer's vision, ensuring the complete display of the goods. According to the information fed back by the temperature sensor, the controller automatically controls the working status of the thin-film heating wire 203 and the air pump 401. When the glass temperature is lower than the set value, the controller starts the heating wire to heat; when the glass temperature reaches the set value, the controller stops the heating wire and uses the air pump 401 to draw gas from inside the cabinet 1 and spray it onto the surface of the cabinet door assembly 2 to help the temperature of the cabinet door assembly 2 return to the same state as inside the cabinet 1. This realizes the automatic control of the heating wire, avoids unnecessary energy consumption, and reduces operating costs.

[0042] The sliding connection between the support groove 302 and the support plate 301 allows the support groove 302 to be pulled out during replenishment operations, facilitating replenishment. The engagement between the limiting block 306 and the limiting groove maintains the stability of the support groove 302 in the storage state.
