Technical Field

[0001] This invention relates to the field of food vending machine technology, specifically a convenient fully automatic food vending machine. Background Technology

[0002] Nowadays, the pace of modern life is getting faster and faster, especially in big cities. Brick-and-mortar restaurants have drawbacks such as low efficiency, long distances, and slow food preparation. As for takeout food, it needs to be delivered over a certain distance and time, which will affect the temperature and taste of the food. At the same time, the hygiene of takeout restaurants cannot be guaranteed. Therefore, automated food vending machines have gradually emerged.

[0003] According to a Chinese patent application with publication number 202410815967.9, a convenient fully automatic vending machine is disclosed, which solves the problem that existing automatic vending machines easily waste customers' dining time. It is also suitable for customers with different levels of urgency when dining, thus saving customers' dining time. However, since each meal needs to be heated on a heating platform, customers still need to wait. At the same time, during peak purchasing periods, simply heating each meal on the heating platform can easily lead to excessively long waiting times for subsequent customers. Therefore, we propose a convenient fully automatic vending machine to solve the above-mentioned technical problems. Summary of the Invention

A lunch box rack is fixedly installed on the top of the bottom pad. The lunch box rack and the bottom pad are fixedly installed on the inner wall of the stepped guide slot. The lunch box rack is arranged in a stepped manner, and the height of the lunch box rack gradually increases towards the rear.

[0011] As a preferred embodiment of the present invention, the top of the lunchbox rack is provided with a plurality of telescopic holes evenly distributed to the left, right and front and back. The number of telescopic holes corresponds to the step specifications of the lunchbox rack. Telescopic caps are slidably installed inside the telescopic holes. A blocking plate is fixedly installed at the bottom of the telescopic caps. Four legs are fixedly installed on the outer wall of the blocking plate at equal angles. V-shaped springs are fixedly installed on the top of the legs. The top of the V-shaped springs is fixedly connected to the bottom of the lunchbox rack.

[0012] As a preferred embodiment of the present invention, a sealing gasket is fixedly installed on the top of the blocking plate. The sealing gasket is located around the telescopic cap. The top of the lunch box rack is provided with four steam outlets distributed at equal angles around the telescopic hole. The steam outlets are located on the top of the sealing gasket. The top of the sealing gasket abuts against the bottom of the lunch box rack. The top of the telescopic cap is higher than the top height of the lunch box rack.

[0013] As a preferred embodiment of the present invention, the top of the lunchbox rack is fixedly equipped with a plurality of lunchbox baffles distributed at equal distances to the left and right, the lunchbox baffles dividing the top of the lunchbox rack into a plurality of equally spaced placement areas, and the telescopic hole is located between the left and right lunchbox baffles.

[0014] As a preferred embodiment of the present invention, the two side groove plates on the left and right sides are fixedly installed with a number of vertically distributed crossbeams at their front and rear sides, and the number of vertical crossbeams corresponds one-to-one with the number of bottom pads. The bottom pads are fixedly installed on the top of the front and rear crossbeams.

[0015] As a preferred embodiment of the present invention, multiple honeycomb holes are provided on the lower part of the opposite surfaces of the left and right side troughs. The multiple honeycomb holes are evenly distributed front to back and top to bottom. The honeycomb holes are located at the bottom of the bottommost stepped guide trough and at the top of the water tank. The top of the water tank is filled with pure water, and the honeycomb holes are located at the top of the pure water liquid surface at the top of the water tank.

[0016] As a preferred embodiment of the present invention, a plurality of vertically distributed partition plates are fixedly installed inside the side groove plate. The partition plates are located between two stepped guide grooves. The top of each partition plate is provided with a threaded hole extending downwards. A solenoid valve is fixedly installed on the top of the partition plate. The solenoid valve is fixedly installed inside the threaded hole by threads.

[0017] As a preferred embodiment of the present invention, a grating camera is fixedly installed on the inner side of the side groove plate. There are multiple grating cameras, which are distributed at equal distances vertically and are located between two lunch box racks. A dustproof glass door is installed on the front of the side groove plate by means of a hinge.

[0018] As a preferred embodiment of the present invention, a raincoat is fixedly installed on the top of the metal skin, and the top height of the raincoat gradually decreases towards the rear.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. In this invention, the heating plate heats the pure water at the top of the water tank to generate steam. The steam enters the interior of the left and right side plates, then passes through the interior of multiple solenoid valves from bottom to top, and is discharged from the output end of the solenoid valves. It then enters the cavity area between the top of the bottom pad and the bottom of the lunch box rack through multiple stepped guide channels. Finally, it enters the steam outlet through the gap between the top of the sealing gasket and the bottom of the lunch box rack, thereby heating the bottom of the lunch box at the top of the lunch box rack and ensuring that the lunch box is always warm, so that customers do not need to wait for it to be heated after purchasing.

[0021] 2. In this invention, when the lunchbox on the top of the lunchbox rack is removed, the V-shaped spring sheet in the stored state rebounds and, under the connection of the support legs, drives the blocking plate, telescopic cap and sealing gasket to move upward, so that the top of the sealing gasket abuts against the bottom of the lunchbox rack again, thereby sealing the steam outlet. After that, the steam inside the cavity between the top of the bottom pad and the bottom of the lunchbox rack cannot enter the previous steam outlet, thus preventing steam from leaking out through the steam outlet.

[0022] 3. In this invention, if it is necessary to place some boxed meals inside, the boxed meals can be placed on top of the lunch box rack in the lower part of the vending machine, and the solenoid valves at both ends of the excess lunch box rack can be closed. During heating, steam cannot pass through the closed solenoid valves. Therefore, steam cannot enter the upper part of the vending machine and is concentrated in the lower part of the vending machine, thereby concentrating the heating of the boxed meals in that part and avoiding energy waste.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1 to 8 The technical solution provided by the present invention specifically includes the following embodiments:

[0034] A convenient fully automatic food vending machine includes side trough plates 100, bottom pads 200, metal covers 300, water tanks 400, and heating plates 500. There are two side trough plates 100, which are symmetrically distributed from left to right. The bottom pads 200 are fixedly disposed between the two side trough plates 100, and there are multiple bottom pads 200. The metal covers 300 are fixedly installed on the periphery and top of the two side trough plates 100. The water tank 400 is fixedly installed at the bottom of the two metal covers 300 and is located between the two side trough plates 100. The heating plate 500 is fixedly installed on the top of the water tank 400.

[0035] For further details, please refer to [link / reference]. Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown:

[0036] Multiple stepped guide slots 101, distributed vertically, are provided on the opposite surfaces of the left and right side plates 100. A lunchbox holder 201 is fixedly installed on the top of the bottom pad 200. The lunchbox holder 201 and the bottom pad 200 are fixedly installed on the inner wall of the stepped guide slots 101. The lunchbox holder 201 is arranged in a stepped shape, with the height of the lunchbox holder 201 gradually increasing towards the rear. Multiple telescopic holes 202 are provided on the top of the lunchbox holder 201, evenly distributed horizontally and vertically. The number of telescopic holes 202 corresponds to the stepped specifications of the lunchbox holder 201. Telescopic caps 203 are slidably installed inside the telescopic holes 202, and a blocking plate 20 is fixedly installed at the bottom of the telescopic caps 203. 4. Four equally angled support legs 205 are fixedly installed on the outer wall of the blocking plate 204. V-shaped spring pieces 206 are fixedly installed on the top of the support legs 205. The top of the V-shaped spring pieces 206 is fixedly connected to the bottom of the lunch box rack 201. A sealing gasket 208 is fixedly installed on the top of the blocking plate 204. The sealing gasket 208 is located around the telescopic cap 203. Four equally angled steam outlets 207 are opened on the top of the lunch box rack 201 around the telescopic hole 202. The steam outlets 207 are located on the top of the sealing gasket 208. The top of the sealing gasket 208 abuts against the bottom of the lunch box rack 201. The top of the telescopic cap 203 is higher than the top height of the lunch box rack 201.

[0037] Specifically, by placing packaged lunch boxes one by one onto the top of the lunch box rack 201, the weight of the lunch boxes compresses the telescopic cap 203 downwards, causing it to slide downwards along the inner wall of the telescopic hole 202. This slides down the blocking plate 204, the support leg 205, and the sealing gasket 208, causing the V-shaped spring 206 to deform elastically. Simultaneously, the downward movement of the sealing gasket 208 creates a gap between its top and the bottom of the lunch box rack 201, opening the steam outlet 207. This continues until the bottom of the lunch box is flush against the top of the rack, blocking the steam outlet 207. Subsequently, the heating plate 500 heats the pure water entering the water tank 400, generating steam. The steam enters the interior of the left and right side plates 100, then passes through multiple solenoid valves 2013 from bottom to top, exiting from the output of the solenoid valves 2013 and flowing through multiple stepped guide channels 10. 1. The steam enters the cavity between the top of the bottom pad 200 and the bottom of the lunchbox rack 201, and finally enters the steam outlet 207 through the gap between the top of the sealing gasket 208 and the bottom of the lunchbox rack 201. This heats the bottom of the lunchbox on the top of the lunchbox rack 201, ensuring that the lunchbox is always warm so that customers do not need to wait for it to heat up. When the lunchbox on the top of the lunchbox rack 201 is removed, the V-shaped spring 206, which is in a stored state, rebounds and, under the connection of the support leg 205, moves the blocking plate 204, the telescopic cap 203, and the sealing gasket 208 upward. Finally, the top of the sealing gasket 208 comes into contact with the bottom of the lunchbox rack 201 again, thus sealing the steam outlet 207. After that, the steam in the cavity between the top of the bottom pad 200 and the bottom of the lunchbox rack 201 cannot enter the steam outlet 207, thus preventing steam from leaking out through the steam outlet 207.

[0038] For further details, please refer to [link / reference]. Figure 5 As shown:

[0039] The top of the lunchbox rack 201 is fixedly installed with multiple lunchbox baffles 209 that are evenly distributed on the left and right. The lunchbox baffles 209 divide the top of the lunchbox rack 201 into multiple equal space placement areas. The telescopic hole 202 is located between the left and right lunchbox baffles 209. The front and rear of the left and right side slot plates 100 are fixedly installed with multiple vertically distributed crossbeams 2010, and the number of vertical crossbeams 2010 corresponds one-to-one with the number of bottom pads 200. The bottom pads 200 are fixedly installed on the top of the front and rear crossbeams 2010.

[0040] Specifically, by setting multiple lunchbox baffles 209, the top of the lunchbox rack 201 is divided into multiple left and right placement positions, expanding the placement area on the top of the lunchbox rack 201. At the same time, due to the dividing effect of the lunchbox baffles 209, the lunchboxes placed on the top of the lunchbox rack 201 can be more neatly arranged, making it easier for customers to select. In addition, since the lunchbox rack 201 is supported by two front and rear crossbeams 2010, the overall stability is better, thereby ensuring the stable operation of the vending machine.

[0041] For further details, please refer to [link / reference]. Figure 4 As shown:

[0042] Multiple honeycomb holes 2011 are provided on the lower part of the opposite surfaces of the left and right side trough plates 100. The multiple honeycomb holes 2011 are evenly distributed front and back and top and bottom. The honeycomb holes 2011 are located at the bottom of the bottom stepped guide groove 101 and at the top of the water tank 400. The top of the water tank 400 is filled with pure water, and the honeycomb holes 2011 are located at the top of the pure water liquid surface at the top of the water tank 400.

[0043] Specifically, the heating plate 500 heats the pure water at the top of the water tank 400 to generate steam. The steam enters the interior of the left and right side trough plates 100 through the honeycomb holes 2011 on both sides, and then passes through the interior of multiple solenoid valves 2013 from bottom to top. It is discharged from the output end of the solenoid valves 2013 and enters the cavity area at the top of the bottom pad 200 and the bottom of the lunch box rack 201 through multiple stepped guide channels 101, thereby heating the lunch box.

[0044] For further details, please refer to [link / reference]. Figure 3 As shown:

[0045] Multiple vertically distributed partition plates 2012 are fixedly installed inside the side groove plate 100. The partition plates 2012 are located between the upper and lower stepped guide grooves 101. The top of each partition plate 2012 has a threaded hole extending downwards. A solenoid valve 2013 is fixedly installed on the top of the partition plate 2012. The solenoid valve 2013 is fixedly installed inside the threaded hole by thread.

[0046] Specifically, when it is necessary to place some boxed meals inside the vending machine during use, the boxed meals can be placed on top of the lunch box rack 201 located in the lower part of the vending machine. The solenoid valves 2013 at both ends of the excess lunch box rack 201 are closed. During heating, steam cannot pass through the closed solenoid valves 2013. Therefore, steam cannot enter the upper part of the vending machine and is concentrated in the lower part of the vending machine, thus concentrating the heating of the boxed meals in that part and avoiding energy waste.

[0047] For further details, please refer to [link / reference]. Figure 1 , Figure 8 As shown:

[0048] A grating camera 600 is fixedly installed on the inner side of the side groove plate 100. There are multiple grating cameras 600, which are distributed at equal distances vertically and are located between the upper and lower lunch box racks 201. A dustproof glass door 700 is installed on the front of the side groove plate 100 by hinge rotation.

[0049] Specifically, packaged boxed meals are placed one by one on the top of the lunchbox rack 201, with different priced meals placed in corresponding positions. When a customer purchases a meal, they need to scan the QR code on the front of the vending machine with their mobile phone for authorization. After authorization, the dustproof glass door 700 automatically unlocks, allowing the customer to open the door and select a meal from the top of the lunchbox rack 201. When a customer takes any meal from the top of the rack, the grating camera 600 scans the empty space where the customer has taken the meal, thus determining the price of the meal. The grating camera 600 then transmits the price information to the processing terminal of the vending machine, and the payment is ultimately deducted from the customer's mobile phone. After the customer takes the meal, the dustproof glass door 700 is closed and automatically locked, achieving fully automated vending.

[0050] For further details, please refer to [link / reference]. Figure 1 As shown:

[0051] A raincoat 800 is fixedly installed on the top of the metal skin 300, and the top height of the raincoat 800 gradually decreases towards the rear.

[0052] Specifically, by setting up the raincoat 800, the rainproof effect of this vending machine can be improved. At the same time, since the top height of the raincoat 800 gradually decreases towards the rear, rainwater falls on the top of the raincoat 800 and flows backward along the top of the raincoat 800. Thus, during the process of taking the food, rainwater will not enter the vending machine through the food taking opening, so as to avoid wetting the boxed meals.

[0053] This solution provides a convenient fully automatic meal vending machine. During operation, staff place packaged meals one by one onto the top of the meal box rack 201, assigning meals of different prices to their corresponding positions. The weight of the meals compresses the telescopic cap 203 downwards, causing it to slide downwards along the inner wall of the telescopic hole 202. This movement also causes the blocking plate 204, support leg 205, and sealing gasket 208 to move downwards, resulting in elastic deformation of the V-shaped spring 206. Simultaneously, the downward movement of the sealing gasket 208 leads to… A gap is created between the top of the sealing gasket 208 and the bottom of the lunchbox holder 201, thus opening the steam outlet 207 until the bottom of the lunchbox is flush with the top of the lunchbox holder 201, blocking the top of the steam outlet 207. Then, the heating plate 500 heats the pure water entering the water tank 400, generating steam. The steam enters the interior of the left and right side plates 100 through the honeycomb holes 2011 on both sides, and then passes through the interior of multiple solenoid valves 2013 from bottom to top, exiting through the output of the solenoid valves 2013. The steam is discharged from the outlet and enters the cavity area between the top of the bottom pad 200 and the bottom of the lunchbox rack 201 through multiple stepped guide channels 101. Finally, it enters the steam outlet 207 through the gap between the top of the sealing gasket 208 and the bottom of the lunchbox rack 201, thereby heating the bottom of the lunchboxes on the top of the lunchbox rack 201, ensuring that the lunchboxes are always warm. Customers do not need to wait for heating when purchasing. When purchasing a lunchbox, customers need to scan the QR code on the front of the vending machine with their mobile phones for authorization. After authorization, the machine will automatically shut down. The dustproof glass door 700 unlocks automatically, allowing customers to open it and select a meal from the top of the food container rack 201. When a customer takes any meal from the top of the food container rack 201, the grating camera 600 scans the empty space where the customer has taken the meal, thus determining the price of the meal. The grating camera 600 then transmits the price information to the processing terminal of the vending machine, and the payment is ultimately deducted from the customer's mobile phone. After the customer takes the meal, the dustproof glass door 700 is closed and automatically locked.

[0054] When the lunchbox on top of the lunchbox rack 201 is removed, the V-shaped spring 206, which is in a stored state, rebounds and, under the connection of the support leg 205, moves the blocking plate 204, telescopic cap 203 and sealing gasket 208 upward, so that the top of the sealing gasket 208 abuts against the bottom of the lunchbox rack 201 again, thereby sealing the steam outlet 207. After that, the steam inside the cavity between the top of the bottom pad 200 and the bottom of the lunchbox rack 201 cannot enter the steam outlet 207, thus preventing steam from leaking out through the steam outlet 207.

[0055] When using this vending machine, if it is necessary to place some boxed meals inside, the meals can be placed on top of the meal box rack 201 located in the lower part of the vending machine. The solenoid valves 2013 at both ends of the excess meal box rack 201 should be closed. During heating, steam cannot pass through the closed solenoid valves 2013, so steam cannot enter the upper part of the vending machine and is concentrated in the lower part of the vending machine, thus concentrating the heating of the meals in that part and avoiding energy waste.

[0056] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention.
