Description
Technical field
The present invention relates to electric heating appliance calorific value regulation technology field, in particular to a kind of energy regulators.
Background technique
Energy regulator is widely used in the electric heating control of the kitchen appliances such as electric hot tray, is attached to bimetal leaf by one piece
Resistor disc that is upper and being parallel to load, when a switch is on, resistor disc heating bimetal leaf make bi-metal plate deformed bending driving
Switch disconnects, and resistor disc cooling makes bimetal leaf be returned to original state again after switch disconnects recloses switch, thus obtains
Obtained the circulation on-off action of certain action cycle.The initial position for changing bimetal leaf by adjustment axis, can obtain difference
Switch on and off time ratio (duty ratio), to realize arbitrarily being averaged lower than power at full capacity on load (such as electric hot tray)
Power, thus can step-less adjustment electric hot tray calorific value.

Crimping connection corresponding with the two outer frame 1-8 of movable contact spring, the movable contact spring tache motorice 1-2 and the vertical hook of the temperature-sensitive arm 9-1
The hook portion 9-1-1 Elastic Contact connection of section.
The movable contact spring tongue 1-3 has the inclination angle to the right of α=3 °~8 ° when being in original state.
The distance Lo of the 1st fulcrum 3-1-1 and the 2nd fulcrum 3-1-2 is greater than bow spring 3 and pacifies when the bow spring 3 is in original state
The distance of two fulcrum after dress.
The movable contact spring 1 and the bow spring 3 are manufactured by elastic metallic material stamped from sheetstock, and this example uses hard state stainless steel band
Material.
The working principle and the course of work of this energy regulator and its switch are such that
Under independent switch conditions, when 1 tache motorice 1-2 of movable contact spring is not by external force, since tongue 1-3 is in initial
Moving contact 2 is separated with static contact 7 with certain inclination angle to the right when state, bends what spring 3 was generated due to compressed
Thrust is spaced further apart dynamic and static contact 2,7.
After resistor disc 10, which is packed in, becomes energy regulator on bimetal leaf 9, the temperature-sensitive arm 9-1 of bimetal leaf 9 is horizontal
It is in horizontal straightened condition when section is initial, is bent upwards the tache motorice 1-2 of movable contact spring 1, movable contact spring outer frame 1-8 is because of pressed sheets
4 two arm 4-1 are limited and are generated bending deformation, turn tongue 1-3 clockwise around the root being located at movable contact spring tache motorice 1-2
It is dynamic, left edge of a knife 1-4 is moved downward, drives bow 3 left end of spring to move downward by the 1st fulcrum 3-1-1, it is critical when crossing its
When operating point, bend the force direction of spring 3 by sporting upwards downwards, the driving front tongue 1-3 moves downward rapidly, makes touching
First 2 with 7 wink of static contact dynamic closure, it is shown in Figure 1.
Since moving contact 2 and static contact 7 are closed, 10 heating power of resistor disc keeps the temperature-sensitive arm 9-1 of bimetal leaf 9 horizontal
Section is slowly bent downwardly deformation, and the tache motorice 1-2 of movable contact spring 1 is slowly moved downwards, and tongue 1-3 is around positioned at movable contact spring tache motorice
Root at 1-2 rotates counterclockwise, and moves upwards left edge of a knife 1-4, by the 1st fulcrum 3-1-1 drive bow 3 left end of spring to
Upper movement bends the force direction of spring 3 by sporting downwards upwards, drives the front tongue 1-3 when crossing its critical operating point
It moves rapidly upward, moves moving contact 2 with 7 wink of static contact and separate, it is shown in Figure 2.
Hereafter due to 10 no power of resistor disc, 9 temperature-sensitive arm 9-1 horizontal segment of bimetal leaf tends to horizontal flat because cooling
State makes moving contact 2 and static contact 7 wink dynamic closure again, loops back and forth like this.Rotation, which adjusts wheel shaft 12, makes the first of bimetal leaf 9
Beginning position change can get different switch on and off time ratios (duty ratio).It is required when adjusting screw 11 for setting factory to account for
Empty ratio.
The switch of this energy regulator, characteristic of switch depend primarily on the resiliency characteristics of bow spring 3, bend spring 3 by selecting
Suitable material, design material thickness, width and geomery appropriate, control original state when two pivot distance Lo, then
Stroke needed for can get the disconnection switched, connection, and match with the heat distortion amount of the bimetal leaf of energy regulator 9, thus
Realize the power regulation functions of energy regulator.
Experiments have shown that the above-mentioned assembling parts cost energy adjuster made of common stamped, primary to adjust
Qualification rate is up to 95% or more.
Construction of switch of the invention is not limited only to that it is similar to can also be applied to such as temperature controller needs in energy regulator application
On other electromechanical controllers of functional switch.
