Detailed Implementation
[0021] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.
[0022] Example: An auxiliary cleaning device for food delivery in a smart restaurant, such as... Figures 1-6 As shown, the device includes a mobile base 1, a placement rack 2, a fixed plate 3, a first motor 4, a placement plate 5, a wastewater pipe 7, a wastewater tank 8, a cleaning component 10, and a water supply component. The mobile base 1 is connected to the placement rack 2, and the placement rack 2 is connected to three layers of fixed plates 3, which can deliver multiple dishes at the same time. The first motor 4 is installed at the bottom of the fixed plate 3, and the placement plate 5 is set at the bottom of the fixed plate 3. The output shaft of the first motor 4 passes through the fixed plate 3 and connects to the placement plate 5. A water guide groove 6 is opened on the outer ring of the inner side of the placement rack 2. The water guide groove 6 is lower than the placement plate 5, so that wastewater can flow smoothly into the water guide groove. The wastewater pipe 7 is installed in the placement rack 2 and is connected to the water guide groove 6. The wastewater tank 8 is placed in the mobile base 1. The wastewater tank 8 is provided with a drain outlet 9, which passes through the side plate of the mobile base 1. The placement rack 2 is provided with a cleaning component 10 for cleaning the placement plate 5, and the placement rack 2 is provided with a water supply component for supplying water to the cleaning component 10.
[0023] like Figure 2 and Figure 4 As shown, the cleaning component 10 includes a mounting plate 1001, a second motor 1002, a cleaning column 1003, a scraper 1004, and a guard plate 1005. The mounting plate 1001 is connected to the inner side of the placement rack 2. The second motor 1002 is mounted on the mounting plate 1001. The cleaning column 1003 is rotatably connected between the mounting plates 1001. The output shaft of the second motor 1002 is connected to the bottom of the cleaning column 1003. The scraper 1004 is connected to the cleaning column 1003. The guard plate 1005 is connected to the inner side of the placement rack 2. The width of the guard plate 1005 is greater than the width of the cleaning column 1003, so that the staff will not come into contact with the cleaning column 1003 when placing the food.
[0024] like Figure 2 , Figure 4 and Figure 5As shown, the water supply assembly includes a clean water tank 11, a clean water pipe 13, a water pump 14, and a hose 15. The clean water tank 11 is placed inside the movable base 1. The clean water tank 11 is provided with a water inlet 12, which passes through the side plate of the movable base 1. The clean water pipe 13 is provided inside the placement rack 2. The bottom of the clean water pipe 13 is inserted into the clean water tank 11 and the water pump 14 is installed thereon. The top of the clean water pipe 13 is connected to the hose 15, which is connected to the cleaning column 1003. The cleaning column 1003 is hollow inside and has multiple water outlets 16. The water outlets 16 are located in the middle of the scraper 1004.
[0025] After receiving a customer's order, the system matches the corresponding dishes and delivery location based on the order. Once the dishes are prepared, they are placed on the placement plate 5 of the food cart. At this time, the mobile base 1 is activated, delivering the dishes to the designated location according to the preset route. The design of multiple placement racks 2 can accommodate multiple dishes. When the food cart reaches the designated location and the customer takes the dishes, the food cart begins its return journey. During the return journey, the first motor 4 starts, driving the placement plate 5 to rotate. At the same time, the second motor 1002 also starts, driving... The cleaning column 1003 rotates downwards, and the scraper 1004 connected to the cleaning column 1003 contacts the surface of the placement plate 5, scraping off any remaining soup, residue, or other dirt. The scraped-off dirt will enter the water guide trough 6, and the soup will flow into the wastewater pipe 7 and eventually into the wastewater tank 8. After the scraper 1004 completes the cleaning task, the first motor 4 is turned off, and the second motor 1002 reverses to reset the cleaning column 1003. Then, the wastewater in the wastewater tank 8 is treated in a timely manner, thus saving time in cleaning the placement plate 5.
[0026] During the process of scraping off the soup with the scraper 1004, the water pump 14 is activated, delivering clean water from the clean water tank 11 to the cleaning column 1003 through the clean water pipe 13 and the hose 15. The cleaning column 1003 is hollow inside and has multiple water outlets 16. When clean water sprays out from the water outlets 16, it works in conjunction with the scraper 1004 to rinse the surface of the placement plate 5, ensuring thorough cleaning. At the same time, the operator can replenish the clean water tank 11 with clean water through the water inlet 12 in a timely manner to ensure the smooth progress of the cleaning process.
[0027] like Figure 2 and Figure 3 As shown, it also includes a heating plate 17, which is installed on the placement plate 5 for keeping the food warm.
[0028] The heating plate 17 is used to keep the food warm during delivery, ensuring that the food remains hot and tastes good when it is delivered to the customer.
[0029] like Figure 6 As shown, it also includes mosquito repellent lamps 18, and multiple mosquito repellent lamps 18 are installed on the rack 2.
[0030] The installation of the mosquito repellent lamp 18 effectively prevents mosquitoes from contaminating and interfering with the food.
[0031] like Figure 2 As shown, it also includes an observation window 19, and the side of the movable base 1 is provided with an observation window 19 made of transparent material.
[0032] The observation window 19 is made of transparent material, which can clearly display the water level in the clean water tank 11. When the water level is too low, the operator can promptly detect and replenish the clean water to ensure the smooth progress of the cleaning work.
[0033] Once the order is placed, the system matches the dishes with the delivery location, and the dishes are then placed on the multi-tiered shelf 5 of the food cart. The mobile base 1 drives the food cart to the designated location, completes the delivery, and then returns. At this time, the first motor 4 starts, driving the placement plate 5 to rotate. Simultaneously, the second motor 1002 is also activated, driving the cleaning column 1003 to descend. The scraper 1004 on it is in close contact with the surface of the placement plate 5 to scrape off the remaining soup and residue. At the same time as the second motor 1002 starts, the water pump 14 works simultaneously, sending the clean water in the clean water tank 11 into the cleaning column 1003 through the clean water pipe 13 and the hose 15. Through the water outlet 16 on it, the scraper 1004 works together to rinse the placement plate 5 to ensure thorough cleaning. The dirt flows into the wastewater pipe 7 along the water guide trough 6 and is finally collected in the wastewater tank 8. The heating plate 17 maintains the temperature of the food during the delivery process, the mosquito repellent lamp 18 prevents mosquito interference, and the observation window 19 facilitates monitoring the water level in the clean water tank 11 and replenishing the clean water in time to ensure uninterrupted cleaning operations.
