Description

Technical Field

[0001] The utility model relates to the technical field of food heat preservation, in particular to a food heat preservation device for school meal supply. Background Art

[0002] The food insulation device for school meals is a device used to maintain the temperature of food. It is commonly found in school canteens and other places. Its main functions are insulation, heating and constant temperature, ensuring that food remains hot for a certain period of time so that students can enjoy hot meals during breaks. The insulation device can heat and keep multiple foods warm at one time, reducing the workload of manual heating and insulation, improving work efficiency, and by maintaining the temperature of food, it can extend the shelf life of food, reduce the risk of bacterial growth and food spoilage, and thus ensure food safety.

[0003] After searching, the patent number "CN218355851U" mentioned in the text that "the utility model discloses a canteen food insulation device in the canteen technical field, including a fixed table and a heat preservation tank, a first baffle and a second baffle are arranged on the fixed table, a hot air pipe is arranged on the second baffle, the hot air pipe is connected with an air outlet pipe and a heat absorption component, a heating pipe is arranged in the heat preservation tank, and lifting components are symmetrically arranged on both sides of the front side of the fixed table. The utility model places a food placement plate on the top of the heat preservation tank, heats the water in the heat preservation tank through the heating pipe, and keeps the placement plate and the food in the placement plate warm through the hot water; after the external air is heated by the heating pipe and the hot water through the heat absorption component, it is output to the outside through the hot air pipe. Hot air is sent to keep the air above the heat preservation tank in a warm state, so as to keep the food warm and reduce the cooling speed of the food; the food placement plate is lifted up by the lifting component, so that the edge of the food placement plate is separated from the fixed table, so that the canteen staff can quickly take out the food placement plate. When it is in use, the water in the heat preservation tank is heated by the heating pipe, and the placement plate and the food on the placement plate are kept warm by the hot water. However, it is difficult to drain the water inside the above device after use, and it can only be discharged by manpower, which is time-consuming and laborious. Although the device can heat the food when in use, it cannot control its temperature. When teachers and students eat, they will have the problem that the food is too hot to eat.

[0004] To this end, we provide a school meal insulation device to solve the above problems. Utility Model Content

[0005] The present application provides a food insulation device for school meal supply, which solves the problems of difficulty in draining water after use of the food insulation device and the inability to adjust the temperature.

[0014] It can be seen from the above technical scheme that the present application provides a food insulation device for school meal supply. When in use, the device is first started, and water is injected into the insulation layer through the water injection pipe by a water pump. Then the temperature is set by the control component, and the internal heating pipe heats the water inside the insulation layer. After heating, the staff can place the container containing the food on the placement rack, and then close the protective door to prevent external substances from contaminating the food. After use, the water inside the insulation layer will flow through the filter screen through the drain pipe and enter the collection bin for storage, and the box will be disinfected and sterilized by an ultraviolet sterilization lamp to ensure the cleanliness and hygiene of the box, thereby completing the use of the food insulation device.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. Through the setting of protective components and protective doors, any possible foreign body invasion can be effectively prevented. No matter dust, insects or other impurities, they cannot penetrate the protective doors and enter the interior of the heat preservation device, thus ensuring the original quality and taste of the food to the greatest extent, so that teachers and students can enjoy clean and hygienic meals. In addition, the heat preservation device is also specially equipped with a transparent glass window, which is convenient for teachers and students to clearly and intuitively check the types and freshness of the food inside, and facilitate personalized selection.

[0017] 2. Through the setting of the insulation mechanism, when in use, the water pump will draw water through the water pump pipe and fill it into the insulation layer through the water injection pipe. The hot water pipe at the bottom of the insulation layer can quickly and evenly distribute the heat throughout the device. The heating pipe starts to work to heat the injected water to form a stable heat source. The control component can adjust the internal water temperature and the food temperature to always keep it within a range suitable for direct consumption, ensuring the freshness and taste of the food. After the device is used, the internal water flows through the filter through the drain pipe and into the collection bin for storage so that the staff can handle it. The filter can effectively capture food residues and other fine particles to prevent these debris from entering the subsequent wastewater treatment link. No manpower is required for drainage, which is convenient, fast, trouble-free and labor-saving.

[0018] In summary, the present application filters the wastewater and stores it through the setting of the drainage component, which does not require human participation, saving time and effort, and controls the temperature in the box through the control component to keep the food at a suitable temperature for easy consumption.
