Description

Technical Field

[0001] This utility model relates to the field of insulated food warming station technology, and in particular to a stainless steel insulated food warming station for canteens. Background Technology

[0002] Stainless steel insulated food warming stations for canteens are designed specifically for group dining scenarios such as canteens and restaurants. Made primarily of stainless steel, these stations are equipped with functions for food warming, display, and serving. Their core function is to maintain a suitable temperature to ensure the taste, flavor, and safety of dishes during meal service. They also facilitate staff handling and customer selection. To reduce the impact of food temperature loss over time on food quality, existing stations use container-type warming lids placed directly on the station to prevent heat loss and keep the food warm.

[0003] In existing technology, when serving dishes, staff must first remove the insulated cover covering the serving area before they can serve the dishes. However, since the space at the canteen's food counter is usually quite compact, multiple food containers may be placed on the counter at the same time, and space must also be reserved around the counter for staff to turn around and place tools. As a result, it is often difficult to find a suitable temporary place to put the removed insulated cover. If it is simply placed on the remaining space on the counter, it will further compress the food serving area and increase the restriction on arm movement. This not only reduces the efficiency of serving dishes, but may also cause the dishes to spill due to the cramped operating space, affecting the smoothness of food service. Therefore, it is necessary to improve the canteen's stainless steel insulated food counter to solve the above problems. Utility Model Content

[0004] To address the issue that staff need to remove the insulated covers from the serving area before serving food, but the cafeteria's food counter space is compact, it's difficult to find a suitable temporary place to put the removed covers. If placed in the remaining space on the counter, it will further compress the operating area, restrict arm movement, reduce serving efficiency, and may also cause food to spill due to the cramped space, affecting the smooth flow of food service.

[0005] The technical solution of this utility model is as follows: a stainless steel insulated food stand for canteens, including a stainless steel food stand body, an observation glass fixedly connected to the top of the stainless steel food stand body, a leg fixedly connected to the bottom of the stainless steel food stand body, a heating component set on the stainless steel food stand body, a stainless steel food storage frame set on the stainless steel food stand body, a stainless steel insulated cover slidably connected inside the stainless steel food stand body, a fixed frame fixedly connected to the top of the stainless steel food stand body, a sliding plate slidably connected inside the fixed frame, a stop block fixedly connected to the bottom of the sliding plate, and a spring fixedly connected between the sliding plate and the fixed frame.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please see Figure 1 - Figure 5This utility model provides an embodiment: a stainless steel insulated food stand for canteens, including a stainless steel food stand body 1, an observation glass 4 fixedly connected to the top of the stainless steel food stand body 1, a leg 5 fixedly connected to the bottom of the stainless steel food stand body 1, a heating component set on the stainless steel food stand body 1, a stainless steel food storage frame 21 set on the stainless steel food stand body 1, a stainless steel insulated cover 22 slidably connected inside the stainless steel food stand body 1, a fixed frame 24 fixedly connected to the top of the stainless steel food stand body 1, a sliding plate 26 slidably connected inside the fixed frame 24, a stop block 25 fixedly connected to the bottom of the sliding plate 26, and a spring 28 fixedly connected between the sliding plate 26 and the fixed frame 24. The stainless steel insulated cover 22 is in contact with the top of the stainless steel food storage frame 21, and the stop block 25 is slidably connected inside the stainless steel food stand body 1 and is in contact with the stainless steel insulated cover 22. The compressed spring 28 drives the sliding plate 26 and the stop block 25 to move. The staff only needs to push the switch upwards. The plate 29 moves the block 25 upward to compress the spring 28, allowing the stainless steel heat preservation cover 22 to be slid into the main body for storage via the handle 23. This avoids the heat preservation cover occupying countertop space, freeing up ample area for serving food. When not serving food, the stainless steel heat preservation cover 22 is slid outward to contact the arc end of the block 25, which then lifts the block 25 and compresses the spring 28. Once the heat preservation cover is slid to its outermost position, the compressed spring 28 moves the block 25 downward to achieve a fixed position. The entire process requires no additional placement, simplifying the storage and unfolding of the heat preservation cover and avoiding problems such as low serving efficiency and food spillage caused by limited space. This significantly improves the convenience and smoothness of the stainless steel heat preservation table. The heating component adds water to the heating zone and heats the water through the annular heating tube 33. The temperature sensor 32 enables real-time monitoring and precise control of the heating zone temperature, ensuring that the food is always kept at a suitable heat preservation temperature, thus improving the practicality of the stainless steel food preservation table 1.

[0019] Please see Figure 1 - Figure 4In this embodiment, the stainless steel serving stand 1 is provided with a heating zone and a room temperature zone, and three sets of stainless steel food storage frames 21 are provided. Two sets of stainless steel food storage frames 21 are distributed in the heating zone, and one set of stainless steel food storage frames 21 is distributed in the room temperature zone. By dividing the stainless steel serving stand 1 into heating and room temperature zones and providing three sets of stainless steel food storage frames 21 accordingly, the different characteristics of the dishes can be classified and placed according to their temperature, such as hot dishes needing to be kept warm and cold dishes needing to be stored at room temperature. This avoids the energy waste caused by uniformly keeping all dishes warm or the problem of some dishes being affected by unsuitable temperatures, thus improving the targeted and flexible nature of food preservation and meeting the diversified catering needs of the canteen. The stainless steel serving stand 1 has corresponding placement slots at the corresponding positions of the stainless steel food storage frames 21. A steel vegetable storage frame 21 is installed on the placement groove of the stainless steel serving table body 1. By opening a placement groove on the stainless steel serving table body 1 that is compatible with the stainless steel vegetable storage frame 21, a stable support and positioning can be formed for the stainless steel vegetable storage frame 21, preventing it from sliding or tilting during the serving operation or when the serving table is moved, ensuring the stability of the food storage. It also facilitates the removal, placement and cleaning of the stainless steel vegetable storage frame 21, improving the convenience of daily use. Three sets of stainless steel heat preservation covers 22 are provided, and the three sets of stainless steel heat preservation covers 22 are distributed in sequence at the corresponding positions of the stainless steel vegetable storage frame 21. By setting three sets of stainless steel heat preservation covers 22 corresponding to the positions of the stainless steel vegetable storage frame 21, independent heat preservation control can be achieved for each storage frame. When taking out food from a certain area, simply slide the corresponding cover. The stainless steel heat-insulating cover 22 is positioned at the appropriate location, while heat-insulating covers in other areas remain closed, reducing overall heat loss and helping to maintain stable food temperatures. The stainless steel serving stand body 1 has a matching groove at the corresponding position of the stainless steel heat-insulating cover 22. The stainless steel heat-insulating cover 22 slides within this groove. By providing a matching groove on the stainless steel serving stand body 1, a precise guiding path is provided for the sliding of the stainless steel heat-insulating cover 22, ensuring smooth and stable sliding without jamming or deviation. Simultaneously, the groove provides some protection for the stainless steel heat-insulating cover 22, extending its service life and making its storage neater and more space-saving. The stainless steel serving stand body 1 has a corresponding groove at the abutment block 25. A suitable through groove is provided at the appropriate position. The abutment 25 slides inside the through groove of the stainless steel cooking table body 1. By providing a through groove on the stainless steel cooking table body 1 that matches the abutment 25, the sliding trajectory of the abutment 25 can be strictly limited, ensuring that the abutment 25 can only move up and down along the through groove. This accurately achieves contact and separation with the stainless steel heat preservation cover 22, ensuring the reliability of the spring 28 driving the abutment 25 to perform limit or release operations. One side of the stainless steel heat preservation cover 22 is fixedly connected to the handle 23. A smooth rod 27 is fixedly connected to the top of the sliding plate 26. The smooth rod 27 is slidably connected inside the fixed frame 24. A lever 29 is fixedly connected to the smooth rod 27. Under the action of the handle 23, the operator can easily pull the stainless steel heat preservation cover 22 to slide.The operation is effortless and convenient. Meanwhile, the smooth rod 27 guides the movement of the sliding plate 26, and together with the lever 29, the positions of the sliding plate 26 and the stop block 25 can be easily controlled. This makes the storage and unfolding of the stainless steel heat-insulating cover 22 more flexible and controllable, reducing operating steps and improving food serving efficiency.

[0020] Please see Figure 5 In this embodiment, the heating assembly includes a controller 31 fixedly connected to the stainless steel cooking platform body 1, a temperature sensor 32 fixedly connected inside the stainless steel cooking platform body 1, an annular heating tube 33 fixedly connected inside the stainless steel cooking platform body 1, a drain pipe 34 fixedly connected inside the stainless steel cooking platform body 1, and a one-way solenoid valve 35 fixedly connected to the drain pipe 34. The temperature sensor 32 is electrically connected to the controller 31, the annular heating tube 33 is electrically connected to the controller 31, and the one-way solenoid valve 35 is electrically connected to the controller 31. By adding water to the heating zone and heating the water through the annular heating tube 33, and by using the temperature sensor 32, the temperature of the heating zone can be monitored in real time and precisely controlled, ensuring that the food is always kept at a suitable temperature and improving the practicality of the stainless steel cooking platform body 1.

[0021] During operation, the stainless steel serving stand 1 is first stabilized using the support 5. The operator then places three sets of stainless steel food storage baskets 21 into the corresponding slots on the serving stand 1. Based on the characteristics of the dishes, hot dishes are placed in the two sets of baskets 21 in the heating zone, and cold dishes are placed in the one set of baskets 21 in the room temperature zone. An appropriate amount of water is added to the heating zone. Subsequently, the controller 31 controls the annular heating element 33 to heat the water in the heating zone. Simultaneously, the temperature sensor 32 monitors the temperature of the heating zone in real time and... Data is fed back to controller 31, which precisely controls the working state of the annular heating tube 33 to maintain a suitable heat preservation temperature in the heating zone and a normal temperature zone. When serving food, if a certain area of ​​food needs to be retrieved, the staff moves the corresponding lever 29 upward, causing the rod 27 and sliding plate 26 to move upward, compressing the spring 28 and moving the stop block 25 upward along the groove, releasing the restriction on the stainless steel heat preservation cover 22. Then, the stainless steel heat preservation cover 22 is slid into the stainless steel serving table body 1 along the slide groove using the handle 23. The stainless steel food storage frame 21 is then exposed for serving. The viewing glass 4 allows customers to easily observe the dishes. After serving, the stainless steel heat-insulating cover 22 is slid outwards along the groove using the handle 23. When its edge contacts the arc end of the abutment block 25, it pushes the abutment block 25 upwards and compresses the spring 28. When the stainless steel heat-insulating cover 22 slides to its outermost position and contacts the top of the stainless steel food storage frame 21, the spring 28 resets, causing the sliding plate 26 and the abutment block 25 to move downwards. The abutment block 25 resets along the through groove and limits the stainless steel heat-insulating cover 22, completing the closure and heat preservation. The temperature sensor 32 is a DS18B20. The temperature sensor 32 mainly includes a temperature-sensitive element and a signal processing circuit. The temperature-sensitive element senses changes in ambient temperature, while the signal processing circuit processes and converts the temperature signal detected by the temperature-sensitive element, enabling it to be output as a digital signal. The working principles of the controller 31, the annular heating tube 33, and the temperature sensor 32 are common techniques in this field and will not be described in detail here.

[0022] Through the above steps, by pushing the lever 29 upwards, the stop block 25 is moved upwards to compress the spring 28. The stainless steel insulated cover 22 can then be slid into the main body by the handle 23 for storage, avoiding taking up counter space and freeing up sufficient area for serving food. When not serving food, the stainless steel insulated cover 22 is slid outwards to push up the stop block 25 and compress the spring 28. After sliding to the outermost end, the compressed spring 28 causes the stop block 25 to move downwards and be fixed. The whole process does not require finding an extra place to put it, simplifying the storage and unfolding of the insulated cover. It avoids low serving efficiency and food spillage due to limited space, improves the convenience of use and the smoothness of food service. This solves the problem that when staff sell food, they need to remove the insulated cover of the serving area before serving food. However, the space at the canteen counter is compact, and it is difficult to find a suitable temporary place to put the removed insulated cover. If it is placed in the remaining space on the counter, it will further compress the operating area and restrict arm movement, which will reduce serving efficiency and may cause food spillage due to limited space, affecting the smoothness of food service.
