Technical Field

[0001] This utility model belongs to the technical field of food warming cabinets, specifically a food warming cabinet that facilitates layered temperature adjustment. Background Technology

[0002] In the catering service industry, food warming cabinets are widely used in restaurants, canteens and fast food chains as key equipment to ensure the quality and taste of food. Traditional food warming cabinets mostly use a single overall heating method, which cannot meet the different temperature requirements of different dishes. This limitation in temperature control greatly affects the presentation quality of the dishes and the eating experience.

[0003] Meanwhile, existing warming cabinets have safety hazards in their structural design. When users take food out or put it in, they need to put their hands into the high-temperature warming chamber, which can easily cause burns due to contact with the high-temperature inner wall or steam. Especially in scenarios with high customer traffic and frequent food pick-up, the risk of burns increases significantly, which not only threatens the personal safety of operators but may also lead to operational disputes.

[0004] Therefore, a food warming cabinet that facilitates layered temperature control is proposed to address the above problems. Utility Model Content

[0029] The hot water circulation component 4 includes multiple corresponding baffles 401 disposed within the water tank 3. The baffles 401 and the water tank 3 form a water guiding channel 402. The two ends of the water guiding channel 402 are respectively connected to an inlet pipe 403 and an outlet pipe 404. Control valves 405 are installed on both the inlet pipe 403 and the outlet pipe 404. The inlet pipe 403 and the outlet pipe 404 are respectively connected to an inlet conduit 406 and an outlet conduit 407. One end of the inlet conduit 406 is connected to a water pump 408. An electric heater 409 is connected to the inlet via a pipe. The inlet of the electric heater 409 is connected to a water tank 410 via a pipe. A water outlet pipe 407 is connected to the side of the water tank 410 near the top. Hot water is circulated into the water tanks 3 in different heat preservation chambers 2 to keep the food warm. A control valve 405 is installed on the water inlet pipe 403 and the water outlet pipe 404 connecting the water tank 3. The valve can control the amount of hot water introduced into the water tank 3, thereby controlling the temperature in the heat preservation chamber 2, so as to facilitate the purpose of stratified temperature adjustment.

[0030] The ejector component 6 includes a threaded groove 601 located in the middle of the rear side of the heat-conducting placement plate 5. The threaded groove 601 is threadedly connected to a threaded rod 602. The end of the threaded rod 602 away from the heat-conducting placement plate 5 passes through the cabinet 1 and is connected to a drive motor 603. When taking out or putting in food, the heat-conducting placement plate 5 can be ejected from the heat-insulating chamber 2 to prevent the user's arm from being inserted into the heat-insulating chamber 2 and causing burns, which can greatly protect the user's safety.

[0031] Specifically, a sealing door 7 is provided on the front side of the insulated chamber 2, and the sealing door 7 is movably connected to the cabinet body 1.

[0032] Furthermore, a control panel 8 and a handle 9 are respectively installed on the sealed door 7.

[0033] Furthermore, a baffle 10 is provided at the top edge of the heat-conducting placement plate 5, and the bottom of the heat-conducting placement plate 5 slides against the top of the water tank 3.

[0034] It is worth noting that the front of the water tank 410 extends through the cabinet 1, and a liquid level window 11 is provided on the front of the water tank 410. A water inlet 12 is provided on the front of the water tank 410 near the top.

[0035] It is worth noting that guide grooves 604 are provided on both sides of the threaded groove 601. The guide grooves 604 are located on the rear side of the heat-conducting placement plate 5. A guide rod 605 is provided in the guide groove 604. The rear end of the guide rod 605 is fixedly connected to the cabinet 1.

[0037] Working principle and process: By opening the sealing door 7 with handle 9, the drive motor 603 of the push-out component 6 is started, which in turn rotates the threaded rod 602. Under the action of the threaded groove 601, the heat-conducting placement plate 5 moves outward to prevent the user's arm from being inserted into the heat preservation chamber 2 and causing burns, which can greatly protect the user's safety. After the food is placed or removed, the heat-conducting placement plate 5 returns to its original position and the sealing door 7 is closed. The water pump 408 of the hot water circulation component 4 is started, and the water in the water tank 410 is introduced into the electric heating element. After being heated, the hot water flows through the water pump 408, the inlet pipe 406, and the inlet tube 403 into the water tank 3. The hot water flows along the water channel 402 formed by the partition 401 and the water tank 3, extending the hot water retention time. Then, it flows through the outlet pipe 404 and the outlet tube 407 into the water tank 410. When it is necessary to control the temperature in different heat preservation chambers 2, it is only necessary to adjust the control valve 405 of the corresponding heat preservation chamber 2 to control the amount of hot water, so as to control the temperature in layers and ensure that the food is at a suitable temperature.
