Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric heating tables, and in particular to a control system of an electric heating table and the electric heating table. BACKGROUND

[0002] An electric heating table is a heating appliance integrating a table and a heater. The electric heating table generates heat through an integrated electric heating element (such as an electric heating wire, a carbon fiber heating body, or a PTC ceramic heater) inside the electric heating table, and the heat is transferred to a user's body to achieve a heating effect.

[0003] The control system of the electric heating table is used to adjust the temperature and power of the electric heating table. A user can set the required temperature and heating mode through the control system. Referring to Figure 1 , the control system of the existing electric heating table includes a plurality of electrical elements, and each electrical element is fixed on an electronic board 100. Among them, the thyristor 200 is a high-power electrical element, and due to its large heat generation, a heat dissipation aluminum sheet 300 is usually installed on one side of the thyristor 200 to cool the thyristor 200 by using the good thermal conductivity of the heat dissipation aluminum sheet 300.

[0004] However, due to the close distance between the thyristor and other electrical elements, even if the heat dissipation aluminum sheet is installed on one side of the thyristor, the heat emitted by the thyristor can still cause the temperature of other electrical elements to rise, resulting in damage to these electrical elements due to high temperature.
