Automatic delayed power-off folding type oriented heat conduction heater used for position below office table

Abstract

The invention relates to an automatic delayed power-off folding type oriented heat conduction heater used for the position below an office table. The automatic delayed power-off folding type orientedheat conduction heater comprises a main heating box and an auxiliary heating box which are internally provided with a mica heating plate A and a mica heating plate B correspondingly. A hot flow guiding piece is further arranged in the auxiliary heating box. The rear outer side wall of the main heating box and the rear outer side wall of the auxiliary heating box are hinged together through hinges,the auxiliary heating box can rotate relative to the main heating box, a delayed temperature control switch is arranged on the front outer side wall of the main heating box, and after being connectedin parallel, the mica heating plate A and the mica heating plate B are electrically connected with an input power source through the delayed temperature control switch. By adoption of the technical scheme, when a user conducts usage, the heater only needs to be placed below the office table, and when the user is in the proper range, the heater is automatically triggered to work; and when the userleaves, delayed powering-off is automatically conducted. Electric energy is saved, the heat preservation effect is improved, the user is prevented from being scalded, and safety is improved. When theheater is not used, the heater can be folded and is convenient to carry.

Description

technical field [0001] The invention belongs to the technical field of household electrical appliances, and in particular relates to an automatic time-delay power-off folding type directional heat conduction heater used under a desk. Background technique [0002] With the improvement of people's material living standards, various heating appliances are widely used in the cold winter. Existing various foot warmers, such as electric heating tables, electric coffee tables, small suns, etc., generally use electricity to make heating wires Heating, the heat energy is transferred to various parts of the human body by the heating wire. As the heat energy transfer direction extends, the heat energy in the air gradually attenuates, which cannot meet people's heating needs. For more heat preservation, reduce the heat energy transfer.

[0002] With the improvement of people's material living standards, various heating appliances are widely used in the cold winter. Existing various foot warmers, such as electric heating tables, electric coffee tables, small suns, etc., generally use electricity to make heating wires Heating, the heat energy is transferred to various parts of the human body by the heating wire. As the heat energy transfer direction extends, the heat energy in the air gradually attenuates, which cannot meet people's heating needs. For more heat preservation, reduce the heat energy transfer. Loss, when people use heating appliances such as electric heating tables, electric coffee tables, and small suns, they often use thermal covers made of cotton cloth to cover the above heating appliances for use. This method reduces the heat transmission loss to a certain extent and improves Heating efficiency, however, because the thermal cover is extremely inconvenient to carry and clean, when the heating equipment use environment changes, it still cannot fully meet people's heating needs, and the thermal cover must be cleaned after use, which also increases people's labor burden. On the one hand, when people work at their desks, the thermal cover is not beautiful. Therefore, the thermal cover is not suitable for the office, and there is no foot warmer equipped with the thermal cover. Due to the large heat loss, it cannot meet the long-term desk in the office. In addition, when people are concentrating on office work, some parts of the body inadvertently touch the foot warmer, which may easily cause burns and other adverse effects
