Description
Technical Field
[0001] The utility model relates to the technical field of food truck drying, in particular to a food truck drying bin with a drying locking system for the bin door. Background Technique
[0002] A food truck is a box-shaped trolley used for transporting meals on airplane flights. In meal production by in-flight catering enterprises, a large number of food trucks need to be cleaned. To ensure food safety, the food trucks for assembling meals need to be kept dry without water accumulation after cleaning. The existing methods for drying the trucks mostly involve static cooperation with manual wiping. This method is simple to operate and has a low operation cost. However, the problems are that drying in a static state is slow and the wiping and cleaning strength is insufficient, posing a potential food safety hazard. For drying a large number of food trucks, it cannot be efficiently applied.
[0003] Therefore, in view of this problem, the existing design has proposed a food truck drying bin, that is, moving the cleaned food truck into the drying bin and using high-temperature gas to dry the truck. However, the existing bin door of the drying bin only serves a simple opening and closing function, and its sealing strength is insufficient, easily causing the air flow inside and outside the bin door, affecting the constancy of the internal temperature. Moreover, when drying the food truck inside the bin, there are often problems that the staff forget to close the bin door or do not fully close it, resulting in the loss of high-temperature gas from the bin door, affecting the drying efficiency and causing waste of resources.
[0004] Therefore, in view of the above existing problems, the present technical solution proposes a food truck drying bin with a drying locking system for the bin door. Content of the Utility Model
[0005] The purpose of the utility model is to provide a food truck drying bin with a drying locking system for the bin door to solve the problems raised in the above background technique.
[0006] To achieve the above object, the present utility model provides the following technical solution: A food truck drying bin with a drying locking system for the bin door, comprising a food truck drying bin and a PTC heating system; the PTC heating system is arranged on one side of the outer top of the food truck drying bin, and the high-temperature gas generated by the operation of the PTC heating system is transmitted into the food truck drying bin to dry the food truck transferred into the food truck drying bin. On one side of the front part of the food truck drying bin, there is a truck entrance and exit, and a bin door is hinged on one side of the truck entrance and exit. The bin door is manually pushed to swing to control the opening and closing of the truck entrance and exit. A control box is installed on the upper part of the outer wall of the bin door to control the start and stop operation of the internal and external electrical components of the entire food truck drying bin. On the inner wall edge of the side of the bin door facing the truck entrance and exit, there is a ring of sealing and positioning rings, and a ring of sealing and positioning grooves is provided on the outer wall of the truck entrance and exit corresponding to the sealing and positioning rings. When the bin door is closed, the sealing and positioning rings are snapped into the sealing and positioning grooves to maintain full sealing of the truck entrance and exit. In the middle of one side of the sealing and positioning ring, there is a locking substrate, and a locking groove is provided inside the sealing and positioning groove corresponding to the locking substrate. The locking substrate is inserted into the locking groove, and a pressure drying locking component is arranged inside the locking groove. The pressure drying locking component is electrically connected to the PTC heating system and the control box. A pressing rod for controlling the operation of the pressure drying locking component is provided on the locking substrate. After the bin door is closed to control the accurate engagement of the sealing and positioning ring and the sealing and positioning groove, the locking substrate is inserted into the locking groove. At this time, the pressing rod presses the pressure drying locking component. With the cooperation of the control box, the PTC heating system is synchronously started to generate high-temperature gas, and then the food truck inside the food truck drying bin is automatically dried at high temperature. Thus, on the premise that the bin door is fully closed, the PTC heating system can operate to dry the food truck inside the food truck drying bin, ensuring the sealing inside the food truck drying bin and improving the drying utilization rate of the high-temperature gas.
[0007] Compared with the prior art, the beneficial effect of the present utility model is that the start and stop of the PTC heating system are controlled by the contact or non-contact between the pressure block and the pressure switch, and then the contact or non-contact between the pressure block and the pressure switch is integrated with the sealing and locking of the bin door to the truck entrance and exit. Thus, when the bin door does not close and lock the truck entrance and exit, the PTC heating system is in a stopped state. After the bin door closes the truck entrance and exit, the PTC heating system automatically starts to operate, thereby realizing the full utilization of high-temperature gas and an energy-saving and efficient operation mode.

[0016] The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.
[0017] Please refer to Figures 1 - 4, A food truck drying bin with a drying locking system for the bin door, comprising a food truck drying bin 10 and a PTC heating system 11; the PTC heating system 11 is arranged on one side of the outer top of the food truck drying bin 10, and the high-temperature gas generated by the operation of the PTC heating system 11 is transmitted into the food truck drying bin 10 to dry the food truck transferred into the food truck drying bin 10. There is a truck entrance and exit on one side of the front of the food truck drying bin 10, and a bin door 12 is hinged on one side of the truck entrance and exit. The bin door 12 is manually pushed to swing to control the opening and closing of the truck entrance and exit. A control box 17 is installed on the upper part of the outer wall of the bin door 12 to control the start and stop operation of the internal and external electrical components of the entire food truck drying bin 10 by operating the control box 17. A sealing positioning ring 14 is installed on the inner wall edge of the bin door 12 facing the truck entrance and exit, and a sealing positioning groove 13 is opened on the outer wall of the truck entrance and exit corresponding to the sealing positioning ring 14. When the bin door 12 is closed, the sealing positioning ring 14 is snapped into the sealing positioning groove 13 to keep the truck entrance and exit fully sealed. A locking substrate 19 is installed in the middle of one side of the sealing positioning ring 14, and a locking groove 21 is opened inside the sealing positioning groove 13 corresponding to the locking substrate 19. The locking substrate 19 is inserted into the locking groove 21, and a pressure drying locking component is arranged inside the locking groove 21. The pressure drying locking component is electrically connected to the PTC heating system 11 and the control box 17. A pressing rod 20 for controlling the operation of the pressure drying locking component is arranged on the locking substrate 19. After the bin door 12 is closed to control the accurate engagement of the sealing positioning ring 14 and the sealing positioning groove 13, the locking substrate 19 is inserted into the locking groove 21. At this time, the pressing rod 20 presses the pressure drying locking component. With the cooperation of the control box 17, the PTC heating system 11 is synchronously started to generate high-temperature gas, and then the food truck inside the food truck drying bin 10 is automatically dried at high temperature. Thus, on the premise that the bin door 12 is fully closed, the PTC heating system 11 can operate to dry the food truck inside the food truck drying bin 10, ensuring the sealing inside the food truck drying bin 10 and improving the drying utilization rate of the high-temperature gas.
[0018] In the embodiment of the present invention, a sealing gasket is wrapped on the outer surface of the sealing positioning ring 14 to increase the clamping contact force with the inner wall of the sealing positioning groove 13, thereby increasing the fastening and sealing performance after the bin door 12 is closed; the pressing rod 20 is installed in the middle of the outer side wall of the locking substrate 19, and its end is set as an arc structure;
[0019] The sealing positioning ring 14 and the sealing positioning groove 13 are only arranged and distributed on the non-swing side of the bin door 12 and the truck entrance and exit. A sealing strip is arranged on the swinging side of the bin door 12 and the truck entrance and exit to maintain the sealing after closing and fitting;
[0020] A plurality of positioning pins 15 and positioning holes 16 are evenly arranged on the sealing positioning ring 14 and the sealing positioning groove 13 respectively. The positioning pins 15 are engaged with the positioning holes 16 to further increase the stability after the sealing positioning ring 14 is engaged with the sealing positioning groove 13.
[0021] In an example of the present invention, for the PTC heating system 11, the process of generating high-temperature gas involves the conversion of electrical energy into heat energy. Then, through the heating effect of the PTC heater, the heat is transferred to the surrounding medium, and finally high-temperature gas is generated. When the PTC heater is powered on, an electric current passes through the PTC ceramic heating element. Due to the positive temperature coefficient characteristic of the PTC material, its resistance increases with the increase in temperature, resulting in the generation of Joule heat in the PTC material. In this process, electrical energy is converted into heat energy, causing the temperature of the PTC heater itself and the air in contact with it to rise. As the surface temperature of the heater increases, the surrounding air begins to absorb heat and the temperature gradually rises. When the heated air reaches a certain temperature, it will become high-temperature gas and can then be guided to the area that needs to be heated or discharged through the ventilation system. The above is the operating principle of the PTC heating system 11. Regarding its structure, components, etc., since they belong to the prior art, they will not be elaborated here.
[0022] As a preferred embodiment of the present invention, an observation window 18 is provided on the outer wall of the lower part of the door 12. Through the observation window 18, the drying condition of the food in the drying bin 10 of the food truck can be directly observed.
[0023] As a preferred embodiment of the present invention, the pressure drying locking assembly includes a pressing hole 22 opened in the middle of the locking groove 21. The pressing hole 22 and the pressing rod 20 are correspondingly distributed. A pressure block 26 is telescopically arranged inside the pressing hole 22. The vertical cross-section of the pressure block 26 is set as a T-shaped structure. A through hole for the inner end of the pressure block 26 to telescopically move is opened at the inner end of the pressing hole 22. The diameter of the through hole is smaller than the outer diameter of the pressing hole 22. A plurality of springs 28 are evenly and elastically connected to the stepped ring wall of the pressure block 26. A pressure groove 25 is arranged inside the through hole. A pressure switch 24 is arranged in the middle of the pressure groove 25. One side of the pressure switch 24 is electrically connected to the PTC heating system 11 and the control box 17 through a connecting wire 23. When the outer side of the pressure block 26 is pressed by the pressing rod 20, the springs 28 are compressed. At this time, the inner end of the pressure block 26 passes through the through hole and moves towards the inside of the pressure groove 25, and then contacts the pressure switch 24. At this time, the pressure switch 24 is activated by the force, and then under the connection of the connecting wire 23, it cooperates with the control box 17 to control the PTC heating system 11 to start running;
[0024] It should be noted that the pressure switch 24 is a normally open pressure switch. When the preset pressure is not reached, the switch is off, that is, the contacts are separated; when the pressure increases to the set value, the switch closes, the contacts touch, and thus the PTC heating system 11 is started to operate.
[0025] The working principle of the present utility model is as follows: At the idle part of the device, all the driving parts mentioned above, which refer to power elements, electrical components and the adapted power supply, are connected by wires, and the electrical connection of the working sequence of each electrical component is completed. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and will not explain the electrical control. During operation, the cleaned food food truck is pushed into the interior of the food food truck drying bin 10 along the food truck inlet and outlet, and then the door 12 is manually pushed to swing to close the food truck inlet and outlet. When closing, the sealing positioning ring 14 is clamped with the sealing positioning groove 13, and at the same time, the pressing rod 20 on the locking substrate 19 is inserted into the pressing hole 22 inside the locking groove 21. The pressure block 26 is subjected to the thrust of the pressing rod 20, and the end of the pressure block 26 is controlled to contact the pressure switch 24. At this time, under the connection of the connecting wire 23, the PTC heating system 11 is controlled to operate, and the door 12 synchronously seals the food truck inlet and outlet completely. In this way, the PTC heating system 11 operates to generate high-temperature gas to automatically dry the food truck inside the food food truck drying bin 10. After drying is completed, the door 12 is opened. At this time, the pressure block 26 is separated from the pressure switch 24, and the pressure switch 24 loses pressure, thereby controlling the PTC heating system 11 to close, and then the food truck is removed.
[0026] The above has made a detailed description of the preferred embodiments of this patent. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of this patent.
