Fixing device, heating element assembly and device with heating element assembly

Abstract

The invention provides a fixing device, a heating element assembly and a device with the heating element assembly. The fixing device comprises the following parts of a fixing structure comprising a fixing body and an accommodating cavity provided on the fixing body and suitable for accommodating a heating element, wherein one end of the fixing body is provided with an opening communicated with theaccommodating cavity; a limit structure movably connected to the end of the fixing body with an opening and suitable for moving closer to or away from the accommodating cavity under the action of external force; and a locking structure used to lock the relative position between the limit structure and the fixing body. By adjusting the relative movement between the limit structure and the fixing body, the limit structure and the heating element lean against each other such that the heating element is clamped between the limit structure and the cavity wall of the accommodating cavity to firmlyfix the heating element, thereby fixing the distance between the heating element and the temperature limiter after fixing a temperature limiter on the fixing structure or other structures, so as to effectively ensure and improve the temperature detection effect of the temperature limiter.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a fixing device, a heating element assembly and a device with the heating element assembly. Background technique [0002] At present, there are many electric heating equipment and electrical products on the market. Among them, the heater has a wide range of applications due to its complete functions and convenient use. High, abnormal noise during rotation, etc. These problems also require continuous improvement in the design and technical perfection of the electric heater. [0003] Heating is an important function of the heater. If the heat is not well controlled, the temperature may be too high, resulting in damage to the circuit or deformation of the machine due to high temperature, or even a fire. For this reason, a temperature limiter is generally installed in the heater, and the temperature limiter will disconnect the circuit of the heating element when the hea...

Problems solved by technology

This requires that the distance between the temperature limiter and the heating body is fixed and cannot change greatly. If the distance between the temperature limiter and the heating body is suddenly large or small, it will affect the temperature detection of the temperature limiter. As a result, it will affect the control of the heating element circuit by the temperature limiter, thus causing a safety hazard in the heater

[0004] In the prior art, the temperature limiter is generally fixed on a fixed frame, and the fixed frame is formed with a storage chamber, and the heating element is installed in the storage cavity, and the heating element is limited by the wall of the storage cavity. Although this method can limit the distance between the heating element and the temperature limiter to a certain extent, in order to ensure that the heating element can be smoothly loaded into the accommodating cavity, the size of the heating element is usually made smaller than that of the accommodating cavity. Small, which leads to a gap between the heating element and the accommodating cavity, and the existence of this gap will still change the distance between the heating element and the temperature limiter, thus affecting the temperature limit The detection effect of the device on the temperature
