A power-off reset thermostat

Abstract

The present invention relates to the field of the temperature controller technology, specifically to an outage resetting temperature controller. The outage resetting temperature controller comprises housing, a temperature sensing cover is arranged at the mask at the upper end of the housing, and two power connection terminals pass through the bottom plate of the housing; and the housing is internally provided with a thermo-sensitive piece, a heating tray and a motion mechanism, the heating tray is in matching connection with the upper end port of the housing, and the thermo-sensitive piece is movably arranged between the heating tray and the temperature sensing cover; the motion mechanism is in on-off matching arranged with the two power connection terminals, and the two power connection terminals are electrically connected with the heating tray; and the motion mechanism is provided with an interlocking bar, and the interlocking bar passes through the central through hole and is correspondingly arranged with the thermo-sensitive piece. The outage resetting temperature controller is reasonable in structure and simplified in the number of the temperature controller structure through adoption of the linkage arm with the herringbone arrangement and an elastic tongue piece to match the motion mechanism, the heating tray and the outer edge of the housing match and are integrally assembled to effectively compress the height of the whole structure; and the moreover, the outage resetting temperature controller is compact in layout, convenient to assemble, sensitive in reaction and stable in work in the condition of large current, etc.

Description

technical field [0001] The invention relates to the technical field of temperature controllers, in particular to a 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 circuit is de...

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
