Double-reed temperature controller

Abstract

The invention discloses a double-reed temperature controller, and mainly aims at solving the problem that the single-reed temperature controller is too small in amperage to influence the normal running of the compressor and make the contacts be easy to coke when the international trade refrigerator is started under 110V voltage. The double-reed temperature controller mainly consists of an on / off system and an adjusting system, wherein the on / off system comprises a grounding terminal, a connecting terminal, a longitudinal U-shaped reed, a transverse U-shaped reed, a movable straight reed, a movable contact, a fixed contact, a fixed straight reed, a normally closed movable contact and a normally closed fixed contact; and the adjusting system comprises a temperature adjusting knob, a cam, an adjusting rod, a halt temperature adjusting bolt, a boot temperature adjusting bolt, a hook-shaped lever, an L-shaped lever, a transverse push rod, a capillary temperature sensing probe, a corrugated pipe and a halt temperature fine adjusting bolt. The double-reed temperature controller has the advantage that the diversion area is increased through increasing the double reed, so that when the contacts are closed, the current flowing through the U-shaped reed is amplified, the starting requirement of the compressor is satisfied, the contact coking probability is reduced and the service life of the temperature controller is prolonged.

Description

technical field [0001] The invention relates to a temperature controller for a refrigerator, in particular discloses a temperature controller with double reeds. Background technique [0002] Used in refrigerators above 500 liters (including double-compressor systems and 110V foreign trade refrigerators), the closing reed of the original thermostat circuit is a single reed, the normal working current is 5A, and the maximum current is 8A. It is far from meeting the needs (110V gap is bigger); when the voltage is unstable, it is easy to cause carbonization of the thermostat contacts, poor contact contact, and damage to the compressor caused by overcurrent of the temperature control. Contents of the invention [0003] A double reed temperature controller, explaining to solve the above problems, discloses a new technical solution, including: grounding terminal (1), connecting terminal (2), longitudinal "U" spring (3), horizontal "U" Type spring (4), moving straight spring (5),...
