Description

Technical Field

[0001] This utility model relates to the field of food warming stove technology, and in particular to a modular food warming stove. Background Technology

[0002] A food warmer is a heating device widely used in the catering industry. It is mainly used to keep food warm or continuously heat it, ensuring that the food maintains a suitable temperature during the meal. Compared with traditional heating methods, food warmers have the advantages of uniform heating, controllable temperature, and energy efficiency. They are particularly suitable for scenarios such as buffet restaurants, banquets, and canteens where food needs to be kept warm for a long time. The use of food warmers can not only improve the dining experience, but also effectively reduce energy waste, making them highly practical and economical.

[0003] Currently, most existing cooking stoves use a circulating hot water heat exchange system to keep the food warm. A water pump drives hot water to circulate continuously in a closed pipe network. The hot water flows through the heat exchange surface that contacts the food container, while a constant temperature heating device continuously replenishes the heat, thereby achieving uniform heating and temperature maintenance of the food. This heat preservation method has higher heat conduction efficiency, more uniform temperature distribution, and relatively lower energy consumption.

[0004] However, existing circulating hot water stoves have a fixed structure, with the number of heating units and water system being designed invariably. This means that the equipment cannot be flexibly adjusted according to changes in dining demand during actual use. For example, it is not possible to quickly increase the number of heating units during peak dining hours, or to reduce the heating area during low-traffic periods to avoid energy waste.

[0005] Therefore, there is an urgent need for a modular insulated food stove that can freely combine heating units according to actual needs, thereby improving ease of use and energy efficiency. Utility Model Content

In particular, since the leftmost holding furnace 6 is directly fixed to the mounting pipe 4, only the connecting pipe A8 is provided on it. The base 1 is provided with a sliding groove, through which the moving pipe 11 is slidably installed on the base 1. The connecting pipe B10 is fixedly installed on the moving pipe 11, so that it can be fixed and connected to the holding furnace 6 through the connecting nut 9 and the connecting pipe A8. The sleeve assembly 12 is fixedly installed between the moving pipe 11 and the pump body 5. The moving pipe 11 is connected to the water storage tank 3 through the sleeve assembly 12. The sleeve assembly 12 is composed of five-stage sliding sleeves, which will extend and retract with the movement of the moving pipe 11. The limiting rings 13 are fixedly installed on each sleeve of the sleeve assembly 12. The sleeves of the sleeve assembly 12 are interlocked by the limiting rings 13 to prevent the sleeves of the sleeve assembly 12 from detaching from each other.

[0023] The protrusion of connecting pipe B10 is inserted into the groove of connecting pipe A8 to form a preliminary connection. Then, the connecting nut 9 is rotated, utilizing its threaded engagement with connecting pipe B10 to ensure a tight fit between connecting pipe A8 and connecting pipe B10.
