A compact thermostat

Abstract

The invention relates to the technical field of temperature controllers, and particularly relates to a compact-type temperature controller. The compact-type temperature controller comprises a shell; the upper port of the shell is coated with a temperature sensing cap; two electrical connection terminals are arranged in the bottom plate of the shell in a penetrating mode; a support is fixedly arranged inside the shell; two ends of the support are provided with vertical plates; a thermosensitive piece is transversely arranged between upper ends of the two vertical plates and abuts against the temperature sensing cap; a linkage rod is arranged between an elastic tongue piece and the thermosensitive piece; the lower end of the linkage rod is fixedly connected with the elastic tongue piece; two sides of the elastic tongue piece are both provided with action arms; and the movable ends of the action arms and the two electrical connection terminals are arranged in a vertical corresponding on-off matching mode. The compact-type temperature controller has the advantages that the structure is reasonable; a deformation action of the thermosensitive piece drives the elastic tongue piece to be deformed via the linkage rod, and thus, the action arms on the elastic tongue piece to cut off electrical connection and contact with the electrical connection terminals; the temperature controller structure number is effectively simplified, and the overall structure height is compressed due to flat layout; and the layout is compact, the assembly is convenient, the reaction is sensitive, and operation in a large current working condition is stable.

Description

technical field [0001] The invention relates to the technical field of temperature controllers, in particular to a compact temperature controller. Background technique [0002] The thermostat is a temperature-sensitive controller with automatic action protection, permanent disconnection without power failure, and self-reset function after power failure. It has a wide range of applications and flexible use, especially in various household appliances, which can protect the safety of electrical circuits and avoid damage caused by excessive operating temperatures. Temperature-sensitive controllers need to solve problems such as temperature rise and heat generation, high resistance, and electric strength under the condition of excessive current. Therefore, the internal temperature-sensing sheet and circuit breaker mechanism need to have enough accommodation space, such as the DC temperature-sensitive controller used in automobiles. The overcurrent in the high-power water heater ...

AI Technical Summary

Problems solved by technology

Temperature-sensitive controllers need to solve problems such as temperature rise and heat generation, large resistance, and electric strength under the condition of excessive current. Therefore, the internal temperature-sensing sheet and circuit breaker mechanism need to have enough accommodation space, such as the DC temperature-sensitive controller used in automobiles. The overcurrent in the water heater reaches 35A, and the overcurrent in the temperature sensitive controller of the high-power water heater reaches 40A. Due to the needs of product installation and modeling design, there is an urgent need for a smaller temperature sensitive controller solution. Therefore, how to compress the design to provide A reliable and beautifully designed temperature-sensitive controller product has become an urgent industrial problem that customers and industry companies need to solve
