[0027] In one embodiment, Figure 1 As shown, a mobile dining vehicle is provided, including a dining vehicle body 102, a cleaning device 104, a disinfecting device 106, a cooling device 108 and a hollow box 110, wherein the cleaning device 104, the disinfecting device 106 and the cooling device 108 are all arranged in the box 110, and the box 110 is arranged on the dining vehicle body 102.

[0028] Among them, the mobile dining car, as the name implies, needs to have certain convenience and catering attributes. The dining car body 102 refers to a structure that can be moved and can carry tableware or kitchen utensils. It can be used only to carry tableware and food ingredients, or it can carry kitchen utensils, and the kitchen utensils can process and cook the food ingredients. When the dining car body 102 is used to carry tableware, the dining car body 102 can have a bearing plane, and the number of bearing planes can be multiple, and each bearing plane can be arranged in a stacked structure or in a stepped structure. When the dining car body 102 is used to place food ingredients, the outer surface of the area in contact with the food ingredients can be coated with food-grade materials or structural materials. The dining car body 102 can also be used to carry kitchen utensils, and the kitchen utensils are placed and fixed by building a structure that matches the kitchen utensils. Furthermore, the dining car body 102 can also carry tableware, kitchen utensils and food ingredients at the same time. The structure of the dining car body 102 is not limited in this embodiment. In one embodiment, Figure 1 As shown, the dining car body 102 has a bearing plane.

[0029] The dining cart body 102 that can be easily moved is usually provided with a rolling structure such as rollers or tires for movement, and can also be provided with a platform (carrying plane) for carrying tableware to facilitate the movement of food. The box 110 is provided on the dining cart body 102 and can be placed on the carrying plane of the dining cart body 102, so that the dining cart body 102 can drive the box 110 to move between different dining areas.

[0030] Furthermore, the rollers of the dining cart body 102 may be universal wheels, and the number of rollers may be multiple. For example, the rollers are arranged on the bottom surface of the dining cart body 102 and are evenly arranged around the center of gravity of the dining cart body 102. The dining cart body 102 may also include auxiliary structures such as handles for users to grasp, thereby improving the convenience of users when using the mobile dining cart.

[0031] Optionally, the dining car body 102 may also be designed as a structure corresponding to the box body 110 without designing a load-bearing platform, and the dining car body 102 fixes the box body 110 by connecting the corresponding structure to the outer surface of the box body 110 to prevent the box body 110 from separating from the dining car body 102. Exemplarily, the outer surface of the box body 110 is a rectangular parallelepiped, and the dining car body 102 may be welded with a surrounding rod structure matching the length, width and height of the box body 110, and the surrounding rod structure is used to fix the box body 110.

[0032] The box 110 is a rectangular parallelepiped with a hollow structure, and can also be an irregular shape. The hollow box 110 is provided with a cleaning device 104, a disinfecting device 106 and a cooling device 108, and is also provided with a box door that can be opened or closed for users to place or take tableware. Among them, the user can put the tableware into the box 110, and activate any one or more of the cleaning device 104, the disinfecting device 106 and the cooling device 108 according to the needs, and perform corresponding treatment on the tableware to achieve efficient use of the tableware. Specifically, the cleaning device 104 is used to clean the tableware in the box 110, ensure the cleanliness of the tableware, clean the used tableware, and improve the reuse efficiency of the tableware; the disinfecting device 106 is used to disinfect the tableware, ensure the sanitation and safety of the tableware, sterilize the tableware, and make the reused tableware meet the current sanitation and safety requirements; the cooling device 108 is used to cool the tableware, which can quickly cool the tableware, so that the temperature of the tableware is at a temperature that the user can directly contact, and further improve the reuse efficiency of the tableware. In particular, when the disinfection device 106 may cause the tableware temperature to rise during the disinfection process, the user cannot directly touch and use the tableware, resulting in poor efficiency in the reuse of the tableware. The cooling device 108 can cool the tableware to improve the efficiency of the reuse of the tableware.

[0033] The mobile dining car may also include a processor connected to the cleaning device 104 , the disinfecting device 106 , and the cooling device 108 . The processor may be connected to the interactive device, and the user may interact with the interactive device to control the operation of the cleaning device 104 , the disinfecting device 106 , and the cooling device 108 .

[0034] Furthermore, the cooling device 108 can be arranged not only in the box 110, but also outside the box 110, or on the box 110, so as to conduct the inside and outside of the box 110. Exemplarily, the cooling device 108 can be a refrigerator, which is arranged in the box 110 to cool the inside of the box 110 and thus cool the tableware. In another embodiment, the cooling device 108 can also be an energy conductor, which is arranged outside the box 110 and cools the tableware by taking away the heat from the box 110.

[0035] In one embodiment, the cooling device 108 includes a fan and a ventilation window connecting the inside of the box 110 with the outside, and the fan is arranged in the box 110 at a position corresponding to the ventilation window. The ventilation window is arranged on the box 110, used to conduct the inside of the box 110 with the outside, and can be freely opened or closed under the control of the user or the control logic of the processor. The fan is arranged in the box 110 at a position facing the ventilation window, and can blow air to the ventilation window. When the ventilation window is opened, the gas exchange inside and outside the box 110 is accelerated, and the high temperature in the box 110 is brought out to achieve the cooling of the tableware. Further, the fan of the cooling device 108 can be a fan, and can be a large-sized fan, which can accelerate the air circulation, on the one hand, make the temperature in the box 110 more uniform, and on the other hand, the cooling rate is faster when the tableware is cooled.

[0036] In this embodiment, the mobile dining car includes a dining car body 102, a cleaning device 104, a disinfecting device 106, a cooling device 108 and a hollow box 110, wherein the cleaning device 104, the disinfecting device 106 and the cooling device 108 are all arranged in the box 110, and the box 110 is arranged in the dining car body 102. The cleaning device 104 is used to clean the tableware in the box 110, the disinfecting device 106 is used to disinfect the tableware, and the cooling device 108 is used to cool the tableware. By cleaning, disinfecting and quickly cooling the tableware for reuse, the utilization efficiency of the tableware in the mobile dining car is improved, which is conducive to the efficient recycling of the tableware on the basis of meeting the hygiene and safety requirements.

[0037] In one embodiment, the cleaning device 104 includes a water circulation unit and a cleaning unit. The cleaning unit is connected to the water circulation unit and is arranged on the inner wall of the box 110. The water circulation unit is used to supply water to the cleaning unit and collect waste water after the cleaning unit cleans the dishes.

[0038] The cleaning device 104 can clean the tableware, specifically, the washing unit can clean the tableware, and the water used by the washing unit to wash the tableware is supplied by the water circulation unit. That is, the water circulation unit is connected to the washing unit, supplies water to the washing unit, and at the same time, the water circulation unit also collects the waste water generated after the washing unit washes the tableware, and the waste water can be used again to supply water to the washing unit after being treated.

[0039] The cleaning unit is used to clean the tableware, which can be to use water to flush the stains on the surface of the tableware, or to soak the tableware in water. The cleaning method of the tableware is not limited in this embodiment. The cleaning unit is usually arranged near the upper part of the inner wall of the box body 110, and the tableware is cleaned by spraying water. The cleaning unit can also mix detergents and other substances that are conducive to cleaning the tableware into the water, so that the tableware can be cleaned.

[0040] The water circulation unit can recycle water resources, which helps to complete the cleaning of tableware. Usually, the water circulation unit will collect the waste water after cleaning on the inner wall of the box body 110. For example, the water circulation unit collects waste water on the bottom inner wall of the box body 110, which can be collected by pumping the waste water through a water pump structure, or by gathering and collecting the waste water through a floor drain structure. Exemplarily, the water circulation unit is arranged at the bottom of the box body 110, and the bottom of the box body 110 is arranged as an inclined surface with a certain slope, and a water leakage port is arranged at the lowest point of the inclined surface, and the water circulation unit collects the waste water generated after the tableware is cleaned through the water leakage port. The water circulation unit can also set the bottom of the box body 110 as a plane with multiple water leakage ports, and collect waste water through each water leakage port.

[0041] The water circulation unit can process the collected wastewater, recycle it, and output it to the cleaning unit to clean the tableware. In one embodiment, the water circulation unit includes a water storage tank and a filter element. The water storage tank is connected to the filter element and the cleaning unit to transfer the water in the water storage tank to the cleaning unit. The filter element is used to collect the wastewater after the cleaning unit cleans the tableware, and transmit the wastewater to the water storage tank after filtering.

[0042] Specifically, clean water is stored in the water tank and can be directly output to the cleaning unit. The collected wastewater needs to be filtered by the filter element before it can flow into the water tank. The filter element can filter out impurities in the wastewater to ensure that the water circulating in the cleaning device 104 maintains its cleaning power. It can also reduce the weight of the mobile dining car and delay the working time of the cleaning device. The filter element includes a filter element, which filters the wastewater, wherein the filter element is detachable and can be replaced by the user. Furthermore, the water tank can also be configured as a detachable structure to facilitate the user to replace, add water to, and clean the water tank.

[0043] Furthermore, the water circulation unit also includes a purification component, and a purification component can be provided between the water storage tank and the cleaning unit, and the water storage tank is connected to the cleaning unit through the purification component. The purification component can further purify the water quality and improve the cleaning efficiency of the cleaning device 104. The water circulation unit can also include a booster pump, which can be provided on the pipeline connecting the water storage tank and the cleaning unit to ensure the water flow output and water pressure of the cleaning unit.

[0044] In order to ensure stable operation, the water in the water circulation unit can be tested. In one embodiment, the water circulation unit also includes a water level sensor, which is arranged in the water storage tank.

[0045] Specifically, the water temperature sensor is arranged in the water tank, and can monitor the water level in the water tank, and can generate an alarm when the water level is too low (lower than a preset water level). The mobile dining car can also include a processor connected to the cleaning device 104, the disinfection device 106 and the cooling device 108, and the processor can receive the alarm and can prompt the user by displaying, uploading to the cloud, or sounding a prompt light.

[0046] In order to enhance the cleaning power and ensure the cleaning effect of the cleaning device 104, the cleaning device 104 can also use hot water to wash the dishes. In one embodiment, the cleaning device 104 also includes a heating unit disposed in the water circulation unit, and the heating unit is used to heat the water in the water circulation unit.

[0047] Specifically, the heating unit can heat the water in the water circulation unit so that the water output from the cleaning unit has a certain temperature, and oil stains can be removed more easily with hot water, thereby improving the cleaning effect. Optionally, the heating unit can be a resistance wire or a semiconductor heating sheet. In this embodiment, the type and structure of the heating unit are not limited, and it only needs to be able to heat the water in the water circulation unit.

[0048] Furthermore, the heating unit can be arranged in the filter element or the water tank, in the pipeline between the cleaning unit and the water tank, or in the pipeline between the filter element and the water tank. The heating unit can be arranged inside or outside the water tank, or inside or outside the pipeline, which is not limited in this embodiment.

[0049] The cleaning unit may be a high-pressure nozzle, and the number of high-pressure nozzles may be multiple and is not limited. In one embodiment, the cleaning unit includes a first spray member and a second spray member, which are arranged at different positions of the inner wall of the box body 110 and are both connected to the water circulation unit.

[0050] Specifically, the water output by the water circulation unit is used to clean the tableware through the first spray member and the second spray member. The first spray member and the second spray member are arranged at different positions of the inner wall of the box 110, and can spray the tableware in the box 110 at different angles, so as to clean the tableware in a more comprehensive manner. Furthermore, the first spray member and the second spray member can be symmetrically arranged relative to the central axis of the box 110, so as to further adjust the cleaning angle and improve the cleaning effect. For example, when the first spray member is arranged on the left side of the inner wall of the box 110, the second spray member can be arranged at the same height on the right side inside the box 110. When the first spray member is arranged on the top surface inside the box 110, the second spray member can be arranged at a relative position of the bottom surface inside the box 110. Optionally, the first spray member and the second spray member can also be rotary spray members, which can change the cleaning angle and improve the cleaning effect.

[0051] In one embodiment, the first spraying member includes a plurality of spraying ports arranged in a linear manner.

[0052] As the shape of the spray piece is different, different spray ports can also be set on each spray piece. When there are multiple spray ports, the spray ports can be arranged linearly, distributed in a circle, or evenly distributed or irregularly distributed. Specifically, when the first spray piece is a rectangular parallelepiped, the spray ports can be arranged in sequence according to the long sides of the first spray piece, that is, arranged in a linear arrangement. When the first spray piece is a cylinder, the spray ports can be distributed in a circle according to the shape of the bottom or top surface of the first spray port; they can also be set on the side of the first spray port and evenly distributed on the side of the first spray port. When the first spray piece is an irregular shape, the design of the spray ports can also be arranged in an irregular shape.

[0053] It should be noted that the second spray part can also be designed with a spray port as described above. And the cleaning unit can include a larger number of spray parts, all of which can be designed with spray ports according to the above records, and the shape of the spray port can also be independent of the shape of the spray part. Exemplarily, the first spray part is an upper spray arm, the second spray part is a lower spray arm, and both the upper spray arm and the lower spray arm can rotate and work along the set top surface or bottom surface. The upper spray arm is arranged on the bottom surface of the inner wall of the box body 110, and the lower spray arm is arranged on the bottom surface of the inner wall of the box body 110. The upper spray arm and the lower spray arm are both rectangular parallelepipeds, and are provided with a plurality of linearly arranged spray ports.

[0054] When the user turns on the cleaning function, the cleaning device 104 starts. At this time, the water in the water tank flows into the purification element to purify the water quality, and then is pumped and transmitted to the two spray arms of the cleaning unit through the booster pump. The tableware is rinsed 360 degrees through high-pressure spraying and rotation. The waste water after rinsing flows into the filter element set at the bottom. After being purified by the filter element, it flows into the water tank for storage, and is pumped back into the spray arm to re-clean the tableware when needed. This reciprocating cycle continues until the cleaning function runs for a preset time, that is, the cleaning time reaches the set threshold time T1 (such as 30 minutes). At this time, the tableware has been cleaned and the cleaning function stops running.

[0055] In one embodiment, the disinfection device 106 includes a heating element and an ultraviolet irradiation lamp, and the heating element and the ultraviolet irradiation lamp are both arranged on the inner wall of the box 110 for disinfecting tableware.

[0056] The heating element can generate high temperature, and the tableware can be sterilized by the generated high temperature. The heating element can be used as a heating unit in the cleaning device 104, and heat the water in the water circulation unit while performing high temperature sterilization. The ultraviolet irradiation lamp can emit ultraviolet rays, which have a bactericidal effect and can reduce the content of bacteria and germs on the surface of the tableware to ensure hygiene and safety.

[0057] Specifically, the heating element is arranged on the inner wall of the box 110, and the tableware in the box 110 can be sterilized at high temperature. In order to evenly transfer the temperature of the heating element to each tableware, the heating element can be arranged at the center of a certain inner wall surface of the box 110. When there are multiple heating elements, they can be arranged on multiple inner wall surfaces. If the heating element also needs to heat the water of the water circulation unit, the heating element can be arranged in a position close to the pipeline or water tank in the box 110. The ultraviolet irradiation lamp is arranged on the inner wall of the box 110. In order to enable the ultraviolet rays to fully irradiate the tableware, the ultraviolet irradiation lamp can be arranged at the center of a certain inner wall surface of the box 110. If there are multiple ultraviolet irradiation lamps, they can be arranged at the center of multiple inner wall surfaces, and multiple ultraviolet irradiation lamps can also be arranged in an array on a certain inner wall surface to make full use of the inner wall space of the box 110. Exemplarily, there are multiple ultraviolet irradiation lamps, which are arranged in an array and arranged on an arrangement plate, and the arrangement plate is arranged on the side inner wall of the box 110.

[0058] In order to conveniently detect the status of tableware, in one embodiment, Figure 2 As shown, the mobile dining car also includes a temperature and humidity sensor 112 disposed in the box body 110 .

[0059] Specifically, the temperature and humidity sensor 112 can be set at any position in the box 110 to detect the temperature and humidity in the box 110. When the temperature data detected by the temperature and humidity sensor 112 is within the preset temperature range, and the humidity data is within the preset humidity range, it indicates that the tableware in the box 110 can be taken. The preset temperature range and the preset humidity range can be set according to actual needs, and are not limited in this embodiment.

[0060] When the cleaning device 104 cleans the tableware in the box 110, even if the cleaning function has been completed, there will still be residual water droplets on the surface of the tableware, and the tableware needs to be dried. Therefore, the mobile dining car can also include a drying device, which can be the heating element in the disinfection device 106 or a separately set heating element, which generates high temperature to evaporate the residual water on the surface of the tableware and reduce the humidity in the box 110.

[0061] Optionally, the drying device further includes an air flow unit for blowing air in the box 110. The air flow unit may be a fan in the cooling device 108, which can not only cool the tableware, but also dry the tableware together with the heating element.

[0062] Exemplarily, since there is still water remaining in the spray arm and the pipeline, the drying function of the drying device can be turned on after the cleaning function is completed after a set time threshold T2 (such as 5 minutes). At this time, the water in the cleaning device 104 basically flows back to the water storage tank, which can avoid drying the water in the pipeline of the cleaning device 104. When the drying function is started, it is necessary to turn on the fan for a preset temperature dissipation time, and then turn on the heating element for drying. As the temperature in the box 110 rises, the humidity gradually decreases. The temperature and humidity sensor 112 detects the humidity data in the box 110 until the humidity data is less than the set humidity threshold (such as 1%), and the drying device completes the drying. At this time, the heating element can be turned off first, and then the fan can be turned off. This can ensure that the wind circulates and evenly delivers heat during drying in the box 110 to avoid excessive local temperatures.

[0063] Furthermore, when the drying function is finished, the disinfection function is turned on and the disinfection device 106 is controlled to start. Among them, since the heating element of the disinfection device 106 can realize the drying function and the high-temperature disinfection function at the same time, in this embodiment, the drying function is completed by the heating element, and the disinfection function is completed by the ultraviolet irradiation lamp. The ultraviolet irradiation lamp is started, and the continuous irradiation time reaches the set threshold value T3 (for example, 20 minutes), and the ultraviolet irradiation lamp is turned off to complete the disinfection.

[0064] When the disinfection device 106 includes a heating element, the tableware will be disinfected at high temperature when the tableware is disinfected, resulting in a higher temperature in the box 110. If the user needs to use the tableware at this time, there may be a risk of scalding. Similarly, when the mobile dining car includes a drying device, the residual water on the tableware will be evaporated and dried, resulting in a higher temperature in the box 110. Therefore, the temperature and humidity sensor 112 can detect the temperature in the box 110, and the user can choose whether to open the door to take the tableware according to the temperature data detected by the temperature and humidity sensor 112. Furthermore, the temperature and humidity sensor 112 can also be connected to a processor, and the processor can control the door of the box 110 to be locked when the temperature data collected by the temperature and humidity sensor 112 is too high to prevent the user from touching it by mistake.

[0065] Furthermore, after cleaning, drying and disinfection are completed, the ventilation window of the cooling device 108 can be opened to achieve gas exchange inside and outside the box 110, and the fan can also be started to use cold air to cool the tableware until the temperature data detected by the temperature and humidity sensor 112 is lower than the set temperature threshold. At this time, the interactive unit of the processor can also remind the user that the tableware is ready and the tableware can be taken, for example, through a display screen and voice to remind the user that the tableware processing is completed and the box door can be opened to take the tableware.

[0066] In one embodiment, the box body 110 further includes a reflective coating, and the reflective coating is disposed on the inner wall of the box body 110 .

[0067] Specifically, the inner wall of the box 110 is also provided with a reflective coating, which reflects light, and can fully reflect the ultraviolet rays in the box 110 to the surfaces of the tableware to achieve comprehensive disinfection. Optionally, the reflective coating can also be a mirror coating to increase the reflectivity of ultraviolet rays. Correspondingly, the ultraviolet irradiation lamp can use a low-energy LED ultraviolet lamp to save energy and extend the working time.

[0068] In order to further ensure the stable operation of the mobile dining car, in one of the embodiments, the mobile dining car also includes a power supply device, which is connected to the cleaning device 104, the disinfection device 106 and the cooling device 108, and is used to supply power to the cleaning device 104, the disinfection device 106 and the cooling device 108.

[0069] Specifically, the power supply device is a mobile battery that can move with the dining car body 102. Correspondingly, a cavity for placing the power supply device can also be provided on the dining car body 102. By providing the power supply device, the mobile dining car can be moved at any time without connecting a power cord, thereby increasing the convenience of the mobile dining car.

[0070] The power supply device can also be connected to the dining cart body 102 to drive the dining cart body 102 to move. For example, if the dining cart body 102 includes a motor and a rolling wheel driven by the motor, the power supply device can be connected to the motor to supply power to the motor so as to facilitate the movement of the mobile dining cart. At the same time, in order to extend the service life of the power supply device, a small flow high-pressure pump can be provided in the cleaning unit in the cleaning device 104, so that a small water flow can be used to rinse the tableware, thereby increasing the utilization efficiency of water resources.

[0071] In order to better understand the above solution, a detailed explanation is given below in conjunction with a specific embodiment.

[0072] In one embodiment, a mobile dining vehicle such as Figure 3 As shown, it includes a dining car body 102, a cleaning device 104, a disinfection device 106, a cooling device 108, a box 110, a temperature and humidity sensor 112, a power supply device (not shown in the figure) and a processor (not shown in the figure), wherein the cleaning device 104 includes a cleaning unit and a water circulation unit, the cleaning unit includes a first spray arm and a second spray arm, the first spray part is an upper spray arm, the second spray part is a lower spray arm, the upper spray arm is arranged on the bottom surface of the inner wall of the box 110, and the lower spray arm is arranged on the bottom surface of the inner wall of the box 110. The upper spray arm and the lower spray arm are both rectangular parallelepipeds, and a plurality of linearly arranged spray ports are arranged thereon. The water circulation unit includes a water storage tank, a filter and a water level sensor. The disinfection device 106 includes a heating element and an ultraviolet irradiation lamp, wherein the heating element can also be used as a drying device to dry tableware. The processor is connected to a display screen, and the display screen is used as an interactive device to interact with the user.

[0073] The user first opens the door of the box 110 and puts the dishes to be cleaned into the box 110. When the water level sensor of the cleaning device 104 detects that the water level in the water tank is higher than the minimum liquid level value, the cleaning function is turned on. If the water level in the water tank is not higher than the minimum liquid level value, the display prompts the user to add water.

[0074] When the user turns on the cleaning function, the cleaning device 104 starts. At this time, the water in the water tank flows into the purification element to purify the water quality, and then is pumped and transmitted to the two spray arms of the cleaning unit through the booster pump. The tableware is rinsed 360 degrees through high-pressure spraying and rotation. The waste water after rinsing flows into the filter element set at the bottom. After being purified by the filter element, it flows into the water tank for storage, and is pumped back into the spray arm to re-clean the tableware when needed. This reciprocating cycle continues until the cleaning function runs for a preset time, that is, the cleaning time reaches the set threshold time T1 (such as 30 minutes). At this time, the tableware has been cleaned and the cleaning function stops running.

[0075] Since there is still water remaining in the spray arm and the pipeline, the drying function of the drying device can be turned on after the cleaning function is completed after a set time threshold T2 (such as 5 minutes). At this time, the water in the cleaning device 104 basically flows back to the water storage tank, which can avoid drying the water in the pipeline of the cleaning device 104. When the drying function is started, it is necessary to turn on the fan for a preset temperature dissipation time, and then turn on the heating element for drying. As the temperature in the box 110 rises, the humidity gradually decreases. The temperature and humidity sensor 112 detects the humidity data in the box 110 until the humidity data is less than the set humidity threshold (such as 1%), and the drying device completes the drying. At this time, the heating element can be turned off first, and then the fan can be turned off. This can ensure that the wind circulates and evenly delivers heat during drying in the box 110 to avoid excessive local temperatures.

[0076] When the drying function is finished, the disinfection function is turned on and the disinfection device 106 is controlled to start. Since the heating element of the disinfection device 106 can realize the drying function and the high-temperature disinfection function at the same time, in this embodiment, the drying function is completed by the heating element, and the disinfection function is completed by the ultraviolet irradiation lamp. The ultraviolet irradiation lamp is started, and the continuous irradiation time reaches the set threshold value T3 (for example, 20 minutes), and the ultraviolet irradiation lamp is turned off to complete the disinfection.

[0077] After cleaning, drying and disinfection are completed, the ventilation window of the cooling device 108 can be opened to achieve gas exchange inside and outside the box 110, and the fan can also be started to use cold air to cool the tableware until the temperature data detected by the temperature and humidity sensor 112 is lower than the set temperature threshold. At this time, the processor reminds the user through the display screen and voice that the tableware processing is completed and the box door can be opened to take the tableware.

[0078] A small flow rate high pressure pump can be provided in the cleaning unit in the cleaning device 104, so that the tableware can be rinsed with a small water flow rate, thereby increasing the utilization efficiency of water resources. Furthermore, the fan of the cooling device 108 can be a fan, and can be a large-sized fan, which can accelerate the air circulation, on the one hand, making the temperature in the box 110 more uniform, and on the other hand, the cooling rate when the tableware is cooled is faster.

[0079] In this embodiment, a mobile dining car with automatic water circulation cleaning function, fan and heating element drying, ultraviolet sterilization, and air cooling of tableware is provided, which realizes the following technologies:

[0080] (1) Clean water is pumped out through a water pump and the tableware is cleaned by high-pressure spraying. The waste water is filtered and then recycled.

[0081] (2) Use the hot air generated by the fan and the heating element to quickly dry the washed dishes.

[0082] (3) Ultraviolet light is used to irradiate tableware from all directions to kill bacteria and viruses.

[0083] (4) Use cold air to quickly cool the sterilized tableware so that it can be used immediately.

[0084] (5) The processor integrates control over each device to achieve automated operation.

[0085] (6) Have a compact and efficient spatial layout that can accommodate all the equipment required for cleaning, drying, sterilizing and cooling tableware.

[0086] The mobile dining car provided in this embodiment is suitable for various mobile catering service scenarios, such as street food stalls, fast food trucks, mobile kitchens, etc. In these scenarios, the mobile dining car provided in this embodiment is energy-saving and environmentally friendly, reduces energy consumption through water recycling and efficient drying technology, and can significantly improve hygiene standards, ensure food safety, and improve service efficiency and user satisfaction.
