Embodiment 1

[0042] The invention discloses an electric heater, such as Figure 1-2 As shown, it includes a housing, a heating component and a safety switch connected in series to the heating circuit. Wherein the housing in this embodiment includes a main body housing 1 (only part of the main housing housing is shown in the figure, and the housing in the front and rear directions is removed for easy understanding of the internal structure) and a top cover 2 connected thereto. There is a heating surface 7, and a heating component 6 is arranged in the main body casing 1, and the heating component 6 is connected with a heating circuit, and the heating component 6 generates heat energy after being energized. Wherein the electric heater of the present invention is a device that heats and releases heat energy by energizing, such as an electric oil heater, a fast-heating furnace type electric heater, and an electrothermal film type electric heater.

Abstract

A safety switch for an electric heater comprises a trigger unit and a switch unit. The switch unit is connected to a heating circuit of the electric heater in series, and is in the normally off state;and the switch unit is trigged by the trigger unit under the effect of external force, and disconnected. According to the electric heater provided by the invention, the outer side of the heating surface of the electric heater is provided with the safety switch, so when the outer side of the heating surface of the electric heater is covered abnormally, the heating circuit can be disconnected through the safety switch in time effectively, and the overheat phenomenon of the electric heater and fire hazards occurred due to coverage are prevented.

Description

technical field [0001] The invention relates to the technical field of heating equipment, in particular to a safety switch for an electric heater and the electric heater. Background technique [0002] As a convenient heating appliance in winter, electric heaters are becoming more and more popular in areas lacking central heating in winter. In addition to being used for indoor heating and keeping out the cold, electric heaters are also commonly used for drying clothes in wet and cold weather. However, due to their own working characteristics, such as Improper use by the user directly covers the electric heater with clothes, etc., which may easily cause the electric heater to overheat and cause a fire. [0003] Existing heaters generally control the temperature rise of the heater by setting one or more thermal circuit breakers between the upper space of the heating element assembly and the air outlet, but usually the thermal circuit breakers use bimetallic strips as temperatur...
