Description

Technical Field

[0001] The present application relates to the technical field of dining carts, and in particular to a disinfection structure and a dining cart. Background Art

[0002] With the development of social economy and the accelerated pace of people's lives, a large number of mobile food trucks are needed in places with large urban and rural population mobility to make up for the shortage of fixed restaurants and provide consumers with nearby catering services. In addition, food trucks have good mobility, are not restricted by venues, and can be used in various environments.

[0003] For environments with high hygiene requirements such as hospital wards, when using dining carts in these environments, it is necessary to ensure that the hygiene of the dining cart itself and the tableware inside the dining cart meets the corresponding standards. The outside of the dining cart can be disinfected directly with disinfectant. At the same time, in order to disinfect the tableware inside the dining cart, high-temperature lamps are installed inside the dining cart to sterilize and disinfect the tableware inside the dining cart by high temperature. At the same time, the high temperature generated by the high-temperature lamps can also keep the food inside the dining cart warm.

[0004] After the dining cart is disinfected or kept warm using high-temperature lamps, a large amount of heat will accumulate inside the dining cart, causing the surface temperature of the dining cart itself and the tableware to be high. Users may easily get burned when taking the tableware, which poses a certain safety hazard. If the dining cart is left stationary for a period of time to dissipate heat, users will need to wait for a long time, resulting in a poor user experience. Summary of the invention

[0005] Based on this, it is necessary to provide a disinfection structure and a dining cart to address the problem that a large amount of heat will accumulate inside the dining cart after the dining cart is disinfected or kept warm by high-temperature lamps, resulting in high surface temperatures of the dining cart itself and tableware.

[0041] See also Figure 1 , Figure 1 A structural schematic diagram of a disinfection structure in an embodiment of the present application is shown. The disinfection structure provided in an embodiment of the present application includes a shell 10, a heating element 20 and a heat exchange module 30. A disinfection space 11 is formed inside the shell 10. The heating element 20 is arranged in the disinfection space 11 to heat the gas in the disinfection space 11, thereby increasing the temperature of the gas in the disinfection space 11 and further increasing the temperature of the overall environment in the disinfection space 11, and finally achieving the purpose of sterilizing the objects in the disinfection space 11.

[0042] Optionally, the items stored in the disinfection space 11 are tableware or lunch boxes, and the tableware or lunch boxes are disinfected and sterilized at high temperature by the heating element 20, so that the tableware and lunch boxes taken out from the disinfection space 11 meet the required sanitary conditions, so as to be used in places with high requirements on the sanitary environment such as hospitals or isolation points. At the same time, the tableware or lunch boxes are placed in the disinfection space 11, and the high temperature generated by the heating element 20 can also keep the tableware and food in the lunch box warm.

[0043] It is understandable that in some other embodiments, the disinfection structure can also be used to sterilize other items such as medical equipment, and the heating element 20 can be a heating lamp tube, etc., which is not limited here.

[0044] Regardless of whether it is tableware, lunch boxes or other items that need to be sterilized, after being sterilized by the high temperature generated by the heating element 20, the surface temperature of the items themselves is within a relatively high range, resulting in the user being unable to directly touch the surface of the items, and also being unable to take the items, which affects the user's work efficiency.

[0045] To this end, the heat exchange module 20 is at least partially located in the disinfection space 11, and a heat exchange medium flows in the heat exchange module 30. The heat exchange medium can pass through the disinfection space 11 during the circulation process. When the heat exchange medium passes through the disinfection space 11, the heat exchange medium can exchange heat with the gas in the disinfection space 11 and transfer the heat of the gas in the disinfection space 11 to the heat exchange medium, thereby reducing the temperature of the gas in the disinfection space 11.

[0046] The above-mentioned disinfection structure heats the gas in the disinfection space 11 through the heating element 20, and the high-temperature gas can disinfect and sterilize the items in the disinfection space 11. Then, the heat exchange medium in the heat exchange module 30 is controlled to pass through the disinfection space 11. When the heat exchange medium passes through the disinfection space 11, it can exchange heat with the gas in the disinfection space 11, thereby reducing the temperature of the gas in the disinfection space 11. After the temperature of the gas in the disinfection space 11 is reduced, the cooled gas can exchange heat with the items in the disinfection space 11 again, which can reduce the temperature of the items in the disinfection space 11, so that the temperature of the items can be quickly cooled down to facilitate users to pick up, reduce the waiting time of users, and improve the user experience.

[0047] In some embodiments of the present application, the heat exchange module 30 includes a water storage component 31 and a circulation pipeline 32. The water storage component 31 stores heat exchange medium. The circulation pipeline 32 is connected to the water storage component 31, and the circulation pipeline 32 passes through the disinfection space 11. The heat exchange medium in the water storage component 31 can enter the circulation pipeline 32 and circulate, so that the heat exchange medium in the water storage component 31 can enter the disinfection space 11 through the circulation pipeline 32 and exchange heat with the gas in the disinfection space 11.

[0048] Optionally, the heat exchange medium can be water, that is, a certain amount of water is stored in the water storage member 31. When the water flows in the circulation pipeline 32, the water can exchange heat with the gas in the disinfection space 11, thereby reducing the temperature of the gas and objects in the disinfection space 11.

[0049] During actual use, the water in the water storage part 31 can be directly replenished by adding tap water. Since tap water is a heat exchange medium that can be easily obtained in life, the gas and objects in the disinfection space 11 can be cooled by water, which can save the cost required for cooling.

[0050] Since tap water is easily available in daily life, after the water exchanges heat between the circulation pipeline 32 and the water storage member 31, the water with increased temperature can be directly discharged from the disinfection structure. Figure 2 One end of the circulation pipe 32 is connected to the water storage part 31, and the other end is connected to the external environment of the disinfection structure after passing through the disinfection space 11, so that the water with increased temperature after heat exchange is discharged from the disinfection structure, and then new tap water is reintroduced into the water storage part 31. The temperature of the newly introduced tap water is lower and can be used for a new round of cooling of the objects in the disinfection space 11.

[0051] However, if the high-temperature water is directly discharged from the disinfection structure and new tap water is reintroduced each time, it will undoubtedly cause a waste of water resources, which is not conducive to energy conservation and emission reduction. Therefore, in some embodiments, refer to Figure 3 One end of the circulation pipeline 32 is connected to the water storage member 31 , and the other end is connected to the water storage member 31 through the disinfection space 11 , and the heat exchange medium circulates between the water storage member 31 and the circulation pipeline 32 .

[0052] In this way, when it is necessary to cool down the items in the disinfection space 11, the heat exchange medium in the water storage part 31 enters the circulation pipe 32. The heat exchange medium exchanges heat with the gas in the disinfection space 11 during the flow in the circulation pipe 32, thereby reducing the temperature of the gas and items in the disinfection space 11. The heat exchange medium after heat exchange returns to the water storage part 31 through the circulation pipe 32.

[0053] In actual use, after the disinfection structure sterilizes the items in the disinfection space 11 through the heating element 20 for the first time, there is often a period of time between the first and second times when the disinfection structure sterilizes the items in the disinfection space 11 through the heating element 20 for the second time. At this time, the heat exchange medium can be cooled in the water storage element 31 by natural cooling or cooling fans and other cooling methods. The cooled heat exchange medium can be used to cool down the high-temperature items in the disinfection space 11 when the disinfection structure sterilizes through the heating element 20 again.

[0054] After the heat exchange medium exchanges heat with the gas in the disinfection space 11, the temperature of the heat exchange medium rises. The heated heat exchange medium itself also has certain practical value, especially when the heat exchange medium is water. The water in the circulation pipeline 32 becomes warm water after heat exchange. In cold environments such as winter, warm water is needed in many cases.

[0055] To this end, in some other embodiments, see Figure 4The disinfection structure also includes a water outlet 33 arranged outside the shell 10. The water outlet 33 can be a nozzle, a faucet, or a water pipe. One end of the flow pipeline 32 is connected to the water storage component 31, and the other end is connected to the water outlet 33 through the disinfection space 11.

[0056] In this way, after the heat exchange medium in the circulation pipeline 32 passes through the disinfection space 11 and exchanges heat with the gas in the disinfection space 11, the temperature of the heat exchange medium increases, and the heat exchange medium with increased temperature can flow out from the water outlet 33. The user can reuse the heated heat exchange medium through the water outlet 33. Taking the heat exchange medium as water as an example, the user can wash hands or rinse items with the heated warm water. The warm water rinse is useful for the user, especially in the cold winter environment, to avoid direct skin irritation by cold water, thereby providing the user with a more convenient cleaning environment.

[0057] In some embodiments, since the user does not need to use warm water every time, in order to avoid wasting water resources, refer to Figure 5 The disinfection structure also includes a tee piece 34. One end of the circulation pipeline 32 is connected to the water outlet piece 33, and the other end is connected to the tee piece 34 through the disinfection space 11. The tee piece 34 is respectively connected to the water storage piece 31 and the water outlet piece 33, and the tee piece 34 can control itself to be connected or disconnected with any one of the water storage piece 31 and the water outlet piece 33.

[0058] In this way, when the user needs to use warm water, the tee piece 34 can be connected to the water outlet piece 33, and the tee piece 34 can be disconnected from the water storage piece 31, so that the heat exchange medium in the circulation pipeline 32 that has been heated by heat exchange can enter the water outlet piece 33 through the tee piece 34, and finally flow out from the water outlet piece 33 to meet the user's need for warm water.

[0059] When the user has no need for warm water, the tee 34 and the water outlet 33 can be disconnected, and the tee 34 and the water storage 31 can be connected to each other, so that the heat exchange medium in the circulation pipeline 32 that has been heated by heat exchange can return to the water storage 31 through the tee 34, thereby being cooled or temporarily stored in the water storage 31 to wait for the next time the user needs to cool down items or use warm water.

[0060] In some embodiments, in order to ensure the efficiency of heat exchange between the heat exchange medium and the gas in the disinfection space 11, the heat exchange module 30 further includes a heat exchange plate 35, which is arranged on the circulation pipeline 32, and the heat exchange plate 35 is located in the disinfection space 11. After the heating element 20 heats the gas in the disinfection space 11 to sterilize and disinfect the items in the disinfection space 11, the high-temperature gas will exchange heat with the heat exchange plate 35, and the heat exchange plate 35 will transfer the heat received by the gas to the heat exchange medium in the circulation pipeline 32, and finally achieve the effect of cooling the gas.

[0061] In some embodiments, the circulation pipeline 32 is located in the disinfection space 11 and extends in a tortuous manner to increase the circulation time of the heat exchange medium in the disinfection space 11. The heat exchange plate 35 provided on the circulation pipeline 32 is combined to enable the high-temperature gas in the disinfection space 11 to fully exchange heat with the heat exchange medium, thereby ensuring the cooling effect of the high-temperature gas.

[0062] In some embodiments of the present application, refer to Figure 1 The disinfection structure also includes a disturbance fan 21, which is arranged in the disinfection space 11 and is used to stir the gas in the disinfection space 11 so that the gas can flow in the disinfection space 11. The flow of gas can not only increase the disinfection and sterilization effect on the objects, but also increase the heat exchange efficiency between the heat exchange medium and the gas in the disinfection space 11.

[0063] Specifically, when the disinfection structure disinfects the items in the disinfection space 11, the heating element 20 heats the gas in the disinfection space 11. At this time, the disturbance fan 21 is started to disturb the gas in the disinfection space 11. The high-temperature gas will flow toward various parts of the disinfection space 11 under the action of the disturbance fan 21, and the items in the disinfection space 11 will be exposed to the high-temperature gas from all directions, so that various parts of the items in the disinfection space 11 can be disinfected by the high-temperature gas.

[0064] After the disinfection structure completes disinfection of the items in the disinfection space 11, the heat exchange module 30 is started, and the heat exchange medium enters the disinfection space 11. At this time, the disturbance fan 21 can also be started. The disturbance fan 21 disturbs the gas in the disinfection space 11. During the flow of the high-temperature gas, it will repeatedly pass through the heat exchange plate 35 in the disinfection space 11 and continuously exchange heat with the heat exchange plate 35, thereby achieving the effect of quickly lowering the gas temperature. After cooling, the gas will continue to exchange heat with the items in the disinfection space under the disturbance of the disturbance fan 21, and finally achieve the effect of quickly lowering the temperature of the items in the disinfection space, further reducing the user's waiting time and improving the user's experience.

[0065] In some embodiments, the disinfection space 11 includes a main disinfection space 12 and a fan heat exchange space 13 that are interconnected. The heating element 20 is arranged in the main disinfection space 12, and the items to be disinfected are also arranged in the main disinfection space 12. The disturbance fan 21 and the heat exchange module 30 are both arranged in the fan heat exchange space 13, and the disturbance fan 21 is located on the side of the heat exchange module 30 away from the main disinfection space 12.

[0066] In this way, the gas extracted or blown into the main disinfection space 12 by the disturbance fan 21 will pass through the heat exchange module 30 during the flow, so that the gas can exchange heat with the heat exchange medium in the heat exchange module 30, thereby ensuring the heat exchange efficiency between the gas and the heat exchange module 30.

[0067] Furthermore, the disturbance fan 21 and the heat exchange module 30 are arranged in the fan heat exchange space 13. While ensuring that the airflow in the main disinfection space 12 can be disturbed, the fan and the heat exchange module 30 will not occupy the space in the main disinfection space 12, so that more items to be disinfected can be stored in the main disinfection space 12.

[0068] It is understandable that in some other embodiments, the disinfection space 11 may not be divided, and the disturbance fan 21 and the heat exchange module 30 may also be all arranged in the disinfection space 11, such as Figure 8 As shown, although the space for placing the items to be sterilized will be occupied, the airflow generated by the disturbance fan 21 is all located in the sterilization space 11, and the sterilization effect and the cooling effect are better.

[0069] In some embodiments of the present application, refer to Figure 6 and Figure 7 In order to further improve the disturbance effect on the air flow, a plurality of spoiler holes 14 are opened on the side wall of the disinfection space 11. When the air flow generated by the stirring fan passes through the spoiler holes 14, the air flow will swirl in the spoiler holes 14, thereby changing the flow direction of the air flow, and finally enabling the air flow to flow in all directions, thereby using the high-temperature air flow to disinfect the objects in the disinfection space 11 in all aspects without dead ends.

[0070] Specifically, the heating element 20 is arranged on the bottom wall of the disinfection space 11. The high-temperature airflow generated by the heating element 20 heating the gas will move upward. During the upward movement, the airflow will contact the spoiler holes 14 on the side wall of the disinfection space 11, thereby changing the direction of the airflow and cooperating with the stirring fan to ensure uniform heat in the disinfection space 11.

[0071] Furthermore, in order to avoid the airflows coming out of the spoiler holes 14 offsetting each other and affecting the gas flow effect, multiple spoiler holes 14 are arranged in an array on the side wall of the disinfection space 11 so that the airflow directions generated by each spoiler hole 14 are roughly the same, thereby ensuring the flow effect of the airflow and reducing the generation of turbulence.

[0072] Specifically in one embodiment, the shell 10 includes a top plate, a bottom plate and multiple side plates, and the multiple side plates are arranged between the top plate and the bottom plate. The top plate, the bottom plate and the multiple side plates are arranged to form a main disinfection space 12, one of the side plates protrudes outward to form a fan heat exchange space 13, and the remaining side plates are provided with spoiler holes 14. A heating element 20 is provided on the bottom plate. The airflow generated by the heating element 20 moves upward and under the action of the disturbance fan 21 and the spoiler holes 14, it fully flows in the main disinfection space 12, ensuring uniform heat distribution and comprehensive disinfection without dead ends.

[0073] Afterwards, when the heat exchange medium begins to circulate, the airflow generated by the disturbance fan 21 will pass through the heat exchange module 30, causing the airflow to cool down. The cooled airflow will fully flow in the main disinfection space 12 under the action of the turbulence holes 14, and exchange heat with the objects in the main disinfection space 12 to reduce the temperature of the objects.

[0074] An embodiment of the present application also provides a dining cart, including a disinfection structure as in any of the above embodiments, through which the lunch boxes and tableware in the dining cart can be disinfected so that the taken-out tableware and lunch boxes meet the required sanitary conditions, so as to be applied to places with high requirements for sanitary environment such as hospitals or isolation points. At the same time, the tableware or lunch boxes are placed in the disinfection structure, and the high temperature generated by the heating element 20 can also keep the tableware and food in the lunch box warm.

[0075] Then, the heat exchange medium in the heat exchange module 30 is controlled to pass through the disinfection space 11. When passing through the disinfection space 11, the heat exchange medium can exchange heat with the gas in the disinfection space 11, thereby reducing the temperature of the gas in the disinfection space 11. After the temperature of the gas in the disinfection space 11 is reduced, the cooled gas exchanges heat with the lunch boxes and tableware in the disinfection space 11, which can reduce the temperature of the lunch boxes and tableware in the disinfection space 11, so that the temperature of the lunch boxes and tableware can be quickly cooled down to facilitate users to take them, thereby reducing the waiting time of users and improving the user experience.

[0076] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0077] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
