Abstract
The utility model discloses a temperature controller used for an electric heating chamber. The temperature controller comprises a housing, and a control structure and a contact press structure that are arranged in the housing. The contact press structure comprises a static contact piece with a contact and a moving contact piece with a contact. The moving contact piece is a bimetallic piece and a magnet is arranged on the bimetallic piece. The other side of the bimetallic piece, opposite to the side on which the magnet is placed, is provided with an extension spring. One end of the extension spring is fixed on the housing and the other end of the extension spring is fixed on the bimetallic piece. The control structure comprises an expansion telescopic temperature control rod and an adjusting turn button that is connected with one end o the expansion telescopic temperature control rod. The other end of the expansion telescopic temperature control rod is provided with a permanent magnet which is arranged to be cooperated with the magnet on the bimetallic piece. A distance between the expansion telescopic temperature control rod and the bimetallic piece is adjusted by the adjusting turn button in a rotary manner. The temperature controller has a simple structure, is convenient to use, enables a temperature control scope to be controlled through rotation of the turn button, allows the temperature control suitable scope to be adjustable, is small in size, and is practical.
Description
Technical field
The utility model belongs to the temperature control field, is specifically related to a kind of electric heating chamber thermostat.
Background technology
In the electric heating chamber, the mechanical type attemperating unit mainly is comprised of housing, a fixed contact and a bimetal leaf moving contact, when indoor temperature changes, bimetal leaf moving contact generation deformation, make dynamic/static contact complete break-make and control, and then reach the effect of regulating indoor temperature, yet the volume of the mechanical type attemperating unit of prior art is larger, structure is comparatively complicated, dismounting inconvenience, and relatively poor to the induction sensitivity of temperature, and unadjustable temperature-control range.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, the electric heating chamber thermostat that can regulate the adaptive temperature scope.
the technical scheme that realizes the utility model purpose is a kind of electric heating chamber thermostat, comprise housing, be arranged on control structure and press structure in housing, described press structure comprises with the static contact of contact and movable contact spring, described movable contact spring is bimetal leaf, described bimetal leaf is provided with suction iron, described bimetal leaf is provided with extension spring and is arranged on the one side opposite with inhaling iron, one end of described extension spring is fixed on described housing, the other end is fixed on described bimetal leaf, described control structure comprises the telescopic temperature control bar that expands, the adjusting knob that is connected with telescopic temperature control bar one end that expands, the other end of the telescopic temperature control bar of described expansion is provided with permanent magnet, permanent magnet on the telescopic temperature control bar of described expansion and the suction iron of described bimetal leaf are equipped with, the distance between the telescopic temperature control bar of described expansion and described bimetal leaf is regulated in described adjusting knob rotation.
Described bimetal leaf is arc, and described suction iron is arranged on the arcwall face of arc bimetal leaf.
Be provided with insulation spacer between described extension spring and described housing.
Its operation principle is summarized as follows: under normal circumstances, bimetal leaf is in critical condition under the acting in conjunction of extension spring and suction iron, at this moment, the movable contact spring of bimetal leaf and the contact closure of static contact are when temperature raises, bimetal leaf generation deformation, the telescopic temperature control bar that expands simultaneously expands and extends, with the Distance Shortened of bimetal leaf, at this moment, the acting in conjunction power of bimetallic deformation power and magnetic attraction is completed and is opened circuit greater than the pulling force of extension spring; When temperature reduced, bimetal leaf resetted, with the amount also cooling contraction of telescopic temperature control bar of expanding, under the acting in conjunction of extension spring and bimetal leaf deformation reset force, reset gradually, and completing circuit closure, the load intensification that powers on; And can regulate by adjusting knob the distance of magnet and bimetal leaf on the telescopic temperature control bar that expands, complete the control to temperature controlled sensitivity, when the close together of magnet and bimetal leaf on the telescopic temperature control bar that expands, only need less variations in temperature can complete temperature control effect, when the distance of magnet and bimetal leaf on the telescopic temperature control bar that expands is larger, need that variations in temperature is larger just can complete temperature control effect, can regulate voluntarily as required, applied widely.
The utlity model has positive effect: of the present utility model simple in structure, easy to use, can regulate temperature-control range by the rotation knob, realized that the temperature control scope of application is adjustable, and the little practicality of volume.
Description of drawings
For content of the present utility model is more likely to be clearly understood, the below is described in further detail the utility model according to specific embodiment also by reference to the accompanying drawings, wherein:
