Description

Technical Field

[0001] The utility model relates to the technical field of food heating and display, in particular to a baozi steam display cabinet with non-contact water level induction and intelligent temperature control. Background Art

[0002] With the improvement of living standards and the increasing requirements of consumers for food quality, baozi steam display cabinets have been widely used in convenience stores, snack bars, supermarkets, restaurants, hotels and other places. However, there are still some problems in the actual use of traditional baozi steam display cabinets on the market at present. For example:

[0003] 1. Traditional baozi steam display cabinets usually adopt contact water level sensors. Such sensors are easily affected by scale and other impurities, resulting in inaccurate water level monitoring or even failure. This not only increases the maintenance frequency of the equipment, but also may not be able to remind in time when the water level is too low, leading to dry burning of the heating tube, posing a great potential safety hazard.

[0004] 2. In terms of energy consumption management, the design of traditional display cabinets does not fully consider the energy-saving requirements. During the steaming process, the lighting device usually remains on or needs to be manually turned off by the user. This method not only wastes energy, but also increases the complexity of operation, which does not conform to the current trend of environmental protection and energy conservation.

[0005] 3. There are also deficiencies in the design of temperature control and timing functions of traditional display cabinets. Users need to manually adjust the temperature control and timing functions, which are complex and error-prone, and cannot ensure the best heat preservation effect of food. This not only reduces the convenience of use, but also affects the taste and quality of food.

[0006] In order to overcome the above problems, the industry usually tries to adopt more precise induction technology or more durable lighting devices. However, these improvement solutions often have new problems in actual applications. For example, although more precise contact sensors reduce errors to a certain extent, they still cannot completely avoid the influence of scale, while more durable lighting devices increase costs.

[0007] Therefore, how to improve the reliability, energy-saving performance and operation convenience of the equipment has become the technical problem to be solved by the utility model. Summary of the Utility Model
