[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0018] This utility model provides a heat insulation device for a heat preservation table, including a heating water tank 10, a control circuit, a controller, and a display, all located inside the heat preservation table cabinet 1. A heat insulation layer 11 is provided on the outside of the heating water tank 10, and the heat insulation layer 11 and the heating water tank 10 are connected by a chuck 12.

[0019] The chuck 12 includes a positioning bolt, a fastening nut, and a load-bearing mounting plate. One end of the positioning bolt is fixedly connected to the outside of the heating water tank 10. The insulation layer 11 has pre-drilled mounting holes, and a load-bearing mounting plate is positioned at each mounting hole, with a mounting hole also located in the center of the plate. When installing the insulation layer 11, the mounting holes are aligned with the positioning bolts and inserted. Finally, the fastening nut is used to tighten the positioning bolts, preventing the load-bearing mounting plate from shifting and thus achieving the connection between the insulation layer 11 and the heating water tank 10.

[0020] The insulation layer 11 includes a polyurethane core board, with mortar mesh fabric on both sides of the polyurethane core board and an aluminum foil layer on the outside of the mortar mesh fabric. The polyurethane core material has excellent thermal insulation properties, reducing the rate of heat dissipation and thus providing better insulation. Therefore, the presence of the insulation layer 11 slows down the rate of heat loss from the water tank, achieving approximately twice the insulation effect of not adding insulation material and reducing heating energy consumption by about 50%.

[0021] An adhesive layer is also applied between the insulation layer 11 and the outer wall of the heating water tank 10. The adhesive layer allows the insulation layer to fit the heating water tank more closely, thus achieving better heat insulation effect.

[0022] The inner top of the heating water tank 10 is used to install the serving basin 15. The inner bottom of the heating water tank 10 is equipped with an electric heating element 16, a temperature sensor, a high water level detector 13, and a low water level detector 14. The high-level detector 13 is installed at the highest point of the water flow limit in the heating water tank 10 to detect whether the water level has reached the overflow line and prevent the serving dish 15 from floating due to buoyancy. The center of the high-level detector 13 is located above the bottom surface of the serving dish 15. This position allows hot water to cover the bottom of the serving dish 15, providing sufficient heat, such as 2mm or 3mm. The installation height of the high-level detector 13 can be adjusted according to actual conditions. The low-level detector 14 is installed at the lowest point of the water flow limit in the heating water tank 10 to detect whether the water level is below the safe operating level.

[0023] The water inlet on the bottom or wall of the heating water tank 10 is connected to a water inlet pipe, and a water inlet solenoid valve is installed inside the water inlet pipe. Specifically, the water level control structure also includes: Core processing unit: This is the central processing module of the controller, usually a microprocessor or microcontroller, responsible for processing water level signals and issuing control commands.

[0024] Water supply drive unit: Receives control commands from the core unit to drive the water supply actuators. These are typically relays or solid-state relays.

[0025] Water supply actuator: namely, water supply solenoid valve, installed on the DN15 water supply pipe at the bottom of the water tank, which opens or closes the water supply to the water tank according to the instructions of the water supply actuator.

[0026] The entire automatic water supply process is executed by the controller and water level detection, requiring no manual intervention.

[0027] The electric heating element 16 and the temperature sensor are both installed below the low water level detector 14 in the heated water tank 10 and are far apart from each other; The bottom of the heating water tank 10 is provided with a heating groove, and the heating pipe 16 is located inside the heating groove. The heating pipe 16 is used to heat the water in the tank. The setting of the heating groove can reduce the volume of the water to be heated, thereby reducing energy consumption and making it more energy-efficient.

[0028] The control circuit is electrically connected to all electrical equipment. The display shows the trigger status of the high water level detector 13, the trigger status of the low water level detector 14, and the temperature sensed by the temperature sensor. The controller controls the start and stop of the electric heating tube 16 and the opening and closing of the water supply solenoid valve.

[0029] The temperature control structure mainly consists of a temperature sensor, a control circuit, a display, and a controller. The temperature sensor is located inside the water tank to measure the water temperature. It is positioned relatively far from the heating element 16 to avoid direct interference from the heating element 16's own temperature, measuring only the water temperature.

[0030] During operation, the temperature sensor collects temperature signals, transmits them to the control circuit, and displays them on the monitor so that staff can know the current water temperature. At this time, staff can use the controller to adjust the start / stop of the heater or the power parameters to achieve the adjustment and control of the water temperature.

[0031] Specifically, its components include: Temperature sensor: Installed inside the water tank, it is used to detect the current temperature of the medium in the tank in real time and generate a corresponding temperature signal. It is usually a thermistor or thermocouple.

[0032] User output and display unit: includes an operating interface and a monitor. The operating interface receives the target temperature value set by the user. The monitor displays the system status in real time, including but not limited to the current temperature value, the set temperature value, the operating mode, and fault codes.

[0033] Core processing unit: This is the central processing module of the controller, usually a microprocessor or microcontroller.

[0034] Power drive unit: Receives control commands from the core processing unit and drives the actuators to operate. It is typically a relay or a solid-state relay.

[0035] Execution unit: namely the heating tube 16 of the water tank, which converts electrical energy into heat energy according to the instructions of the power drive unit to heat the water tank medium.

[0036] Power supply unit: Provides a stable and compatible power supply for all the above electronic devices.

[0037] Specifically, the aforementioned electronic control units, including temperature control structures and water level control structures, are already mature technologies in the field of food warming platforms. In practical applications, existing mature technologies and equipment can be directly adopted. Therefore, their specific circuit composition will not be elaborated here.

[0038] The bottom of the heating water tank 10 is equipped with a partition protective plate 17, which divides the heat preservation cabinet 1 into a top heating space and a bottom application space. The partition protective plate 17 also prevents any debris from the heat insulation material from falling into the bottom application space of the heat preservation cabinet 1.

[0039] The bottom of the insulated cabinet 1 is equipped with a waterproof electrical cabinet 18, a storage cavity, and a water pipe cavity. Their spatial distribution is achieved by two vertical partitions arranged in a T-shape. The waterproof electrical cabinet 18 is located on the right side, and rubber gaskets 19 are installed at all gaps in the cabinet to ensure waterproofing during operation and prevent moisture from entering and affecting the operation of the electrical components of the entire insulated cabinet 1. The storage cavity is located on the left side of the waterproof electrical cabinet and is used to hold miscellaneous items. The water pipe cavity is located at the rear of the waterproof electrical cabinet and is used for water pipe wiring, etc.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
