Description

Technical Field

[0001] This invention relates to the field of heating panel technology for dining tables, tea tables, office desks, and study desks, and particularly to intelligent heating panels. Background Technology

[0002] Current market countertops are relatively limited in function and fail to meet the humanized needs of modern people. For example, they cannot accommodate hot pot, warming dishes, or hand warming, and are difficult to clean with hard-to-reach areas. Some dining tables have built-in rotating dishes for warming dishes, but the dishes are small and have gaps that are difficult to clean and prone to leaking oil and food scraps. Currently, some three-in-one smart heating dining tables on the market only have heating devices on the main board, while the L-side and R-side are not heated. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide an intelligent heating panel that can be used to heat hot pot, warm food, and warm hands on a flat surface. In addition to the main board being able to warm hands, the R and L sides on both sides can also be warmed when unfolded. Furthermore, the desktop is seamless, making it easy to clean and maintain.

[0004] This utility model also provides an intelligent heating panel as described above, comprising: a panel, the upper surface of which has function control markings and a transparent digital tube display screen; a heating wire is disposed between a high-temperature resistant, fireproof, insulating heat insulation board and the panel; the lower surface of the heating wire is covered with heat-insulating aluminum foil; a wooden base plate is fixedly connected to the lower surface of the high-temperature resistant, fireproof, insulating heat insulation board; an over-temperature protection temperature control switch and a temperature probe are electrically connected to the outer surface of the heating wire; the over-temperature protection temperature control switch and the temperature probe are electrically connected to a control circuit main board box; a hidden induction cooker and a terminal block are located in the center of the lower surface of the panel; the control circuit main board box is electrically connected to the induction cooker and the high and low temperature zone heating wires through the terminal block; a hidden induction cooker position is placed in the center of the wooden base plate; a human body induction circuit control box is disposed on the lower surface of the base plate, and the human body induction circuit control box includes a human body infrared induction power supply device, a mobile phone remote control system, and a mobile phone wireless charging function module.

[0005] According to the intelligent heating panel of this utility model, the panel is made of one of the following materials: rock slab, artificial stone, natural stone, solid wood board, and organic tempered glass. The heating wire is a high-temperature resistant silicone fiber heating wire. Users can choose the most suitable material according to their preferences and usage environment, which has good aesthetics and durability.

[0006] According to the intelligent heating panel of this utility model, the heating wire includes a high-temperature zone heating wire and a low-temperature zone heating wire on the main board. The low-temperature zone heating wire is arranged within a range of 15-20 cm inward from the edge of the main board and the low-temperature heating wire on the R-side and L-side. When this technology is used in a three-in-one dining table, the R-side and L-side are connected to a conductive wire and a reset switch, which can realize different temperature control in different areas and meet diverse usage needs.

[0007] According to the intelligent heating panel of this utility model, a control circuit main board box is provided on the lower surface of the panel, and the control circuit main board box includes a touch and voice control function system and a temperature sensing control system, which enhances the user's operating convenience and realizes intelligent adjustment through touch or voice control, thereby improving the user experience.

Automatic switching is achieved through human body sensing technology, saving energy and increasing ease of use.

[0009] Beneficial effects:

[0010] This technology features a smart heating panel with a central high-temperature zone to keep food warm during extended meals, and a 15-20 cm edge zone for hand-warming, providing a comfortable dining experience in cold winters. The three-in-one dining table has hand-warming functions on both the R-side and L-side. When more diners are present, the table can be opened to form a round table; when the R-side and L-side are open, a reset switch activates the power supply and generates heat. When fewer diners are present, the table can be folded into a square table; when the R-side and L-side are folded, the reset switch deactivates the power supply, achieving energy savings. The tabletop senses no one using the table for a set time (default 20 minutes) and automatically shuts off the power when the user leaves the table. Furthermore, users can remotely monitor the product or turn off the power switch via their mobile phones when away from the product, ensuring safer and more worry-free use.

It consists of a temperature sensing element (thermostat), a control mechanism (such as a relay), a housing, and connection terminals. When the temperature is normal, the temperature sensing element maintains the switching state and the circuit is unobstructed. When the temperature rises to the set point, the temperature sensing element reacts (for example, the resistance of the thermistor changes or the voltage of the thermistor changes), triggering the control mechanism to disconnect the circuit and cut off the power supply. This is the existing structure.Temperature probes are used to detect the temperature of equipment, providing real-time temperature data for temperature control and safety protection. They are typically composed of thermistors, temperature sensor chips, etc. Temperature changes cause changes in the electrical properties (such as resistance and voltage) of the temperature-sensing element.
