A compact power-off reset thermostat

Abstract

The invention relates to the technical field of a temperature controller, in particular to a compact outage reset temperature controller. The compact outage reset temperature controller comprises a shell, wherein a temperature sensing cover is arranged on an upper port of the shell, a tray is arranged in the upper port of the shell, a fixed ring is clamped between the upper end surface of a limitation plate and the temperature sensing cover, a thermosensitive sheet is arranged in the fixed ring and is separately matched with the temperature sensing cover and the tray, internal steps are arranged on the inner walls of the shell on the two sides of the limitation plate, an electric connection terminal is arranged in a socket in a penetrating way so that electric connection sheets are arranged at the upper end of the internal steps, leading-out parts are arranged on the electric connection sheets and prop against the tray in an electrical connection way, and an actuating mechanism is arranged in the shell. The compact outage reset temperature controller is reasonable in structure, the tray and a fixed support are positioned by the internal steps and the limitation plate, and all parts are further fixed by package of the temperature sensing cover; the actuating mechanism is matched with a linkage actuating arm and an elastic tongue piece which are arranged in a herringbone way, the structural number of the temperature controller is simplified, flat layout of the mechanism is achieved, and the overall structural height is effectively reduced; and the compact outage reset temperature controller has the advantages of compact layout, sensitive reaction and the like, is convenient to assembly and stable to work.

Description

technical field [0001] The invention relates to the technical field of temperature controllers, in particular to a compact power-off reset 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. Power-off reset means that after the temperature sensitive element deforms and breaks the dynamic and static contacts, the heating circuit is turned on, so that the temperature sensitive element continues to maintain the deformation state under the contact of the heating element, so that the dynamic and static contacts continue to break, requiring manual intervention. Sensitive components return to their original state. Generally speaking, the power-off reset adopts a short-circuit circuit, that is, the dynamic and static contacts in the initial state before the temperature-sensitive element of the main circu...

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
