Description

Technical Field

[0001] The utility model belongs to a temperature controller, in particular to a new type of temperature controller. Background Art

[0002] Thermostats are widely used in many household appliances. Thermostats control the contact or separation of the contacts on the spring in the temperature control by the deformation of the temperature sensing sheet, thereby controlling the connection or disconnection of the circuit, so as to achieve the purpose of temperature control. For example, a new type of thermostat is disclosed in Application No. 202221238642.1. In order to meet the effect of fast heating of high-power electrical appliances, it is necessary to increase the resistance value of the heating wire, but many existing thermostats are realized by replacing the heating wire material, but the price of the heating wire with a high resistance value is much higher than that of the conventional heating wire, which greatly increases the cost of the entire thermostat. There are also some thermostats that increase the length of the heating wire, but increasing the length of the heating wire will increase the volume of the entire thermostat accordingly. However, due to the limited installation space of the thermostat in the electrical appliance, the volume of the thermostat should not be too large, which greatly limits the length of the heating wire, so that the resistance value of the heating wire is difficult to meet the use requirements of high-power electrical appliances, and the scope of application is small. Utility Model Content

[0003] The purpose of the utility model is to provide a novel temperature controller, which can solve at least one of the above problems.
