The mainboard below is the electric heater air outlet, and the air outlet is pushed down to the mainboard. Adopt this automatically controlled door -trip, its simple structure, convenient to use, the installation is all very convenient with the maintenance change, and it is few to consume raw and other materials, the energy saving.
Description
Technical field
The utility model belongs to warmer field of switches, relates generally to a kind of electric controlled door switch be arranged on warmer.
Background technology
Along with the raising gradually of economic condition, living standard also improves constantly, and the attention rate of people to energy-saving and emission-reduction is more and more higher, and cold season, the utilization rate of warmer was high, and the utilization ratio how improving warmer has become the new direction of society research.Also there is impact in the energy consumption size of warmer Switch Controller warmer, switch complex precise, connections etc. all need certain manpower and social cost, and therefore switch designs manufacture is more simple and convenient, more be conducive to reducing processing cost and economize energy, larger to the energy-saving and emission-reduction meaning of social long term growth; Existing sheet type contact-making switch is mostly unbending sheet metal, and its end face contacts as linear contact lay with warmer door, and the cut surface out-of-flatness of this contact, precision is not high, and contact surface easily has wearing and tearing.
Summary of the invention
The utility model provides a kind of buckle-type electric controlled door switch on warmer, and it uses simple installation, with low cost.
The technical solution of the utility model: electric controlled door switch, comprise input switch, this electric controlled door switch also comprises the turnover door that is folded into mainboard and subplate, bimetal leaf and output switch, subplate is stretched in described bimetal leaf one end, and the bimetal leaf other end is connected with output switch.Be electric heater air outlet below mainboard, mainboard pushes down air outlet.
Preferably, described bimetal leaf is corresponding with the upper end of subplate.Bimetal leaf mobilizable one end correspondence is located at subplate end position, when bimetal leaf bends and applies a power to subplate upper end so when the temperature is changed, bimetal leaf is equivalent to the effect of an arm of force, wait other position applied forces just less relative to being arranged in the middle part of subplate, namely bimetal leaf degree of crook is lower just can open turnover door.
Output switch is power switch, controls the dynamics size of bimetal leaf to the applying of turnover door, controls the angular dimension of turnover door upset further, reaches the discharge controlling heat in warmer.Be the non-opening of input switch under normality, sheet metal does not contact with subplate, and turnover door closes air outlet; After input switch opens heating, after input switch opens heating, sheet metal and turnover door contact, namely sheet metal and subplate contact, bimetal leaf heated bending, applies a power to turnover door, the mainboard of turnover door is upwards overturn and opens air outlet, warmer works, and after heating, air-flow is discharged from air outlet eliminating heat from air outlet.
Preferably, mainboard is provided with a pair spacing lug.The angle of described lug restriction mainboard upset.When mainboard stirs under sheet metal effect, mainboard is to the upset of subplate direction, and when lug and mainboard upper surface contact, the ventilating opening below mainboard is opened to maximum angle.After power-off, turnover door is not under pressure, under lug effect, naturally reply shutoff device.
Preferably, described sheet metal is multisection type and bends each other, and first paragraph connects output switch, and the 3rd section is connected with first paragraph by second segment, and described 3rd section is provided with arc flange.Adopt flange, make bimetal leaf and subplate contact surface smoothly, complete line contact improves the accuracy of temperature detect switch (TDS).Input switch is opened, and output switch drives sheet metal stressed bending, and subplate is turned over, and mainboard opens air outlet, and warm braw blows out from air outlet.
Preferably, between described 3rd section and second segment, angle is 90 degree.
Preferably, between second segment and first paragraph, knuckle is greater than 120 degree.
Preferably, described sheet metal is connected with output switch by spacer, and described bimetal leaf first paragraph and spacer are fixed by adjusting bolt.Tightening and loosening the front and back position regulating sheet metal by bolt, control further bimetal leaf in the course of the work bend the thrust applied to turnover door.
The beneficial effects of the utility model: adopt this electric controlled door switch, its structure is simple, easy to use, and I&M is changed all very convenient, expends raw material few, economize energy.

Detailed description of the invention
As shown in the figure, electric controlled door switch is mainly used on warmer, is generally located at warmer top, and it forms primarily of input switch 1, output switch 2, turnover door 3 and bimetal leaf 4, turnover door 3 is made up of mainboard 31 and subplate 32, and mainboard is located at the top of warmer air outlet 71.Under normality, sheet metal does not contact with turnover door, and turnover door closes air outlet; When opening input switch 2, warmer heats, and output switch 2 is opened, and the subplate 32 of bimetal leaf 4 pairs of turnover doors 3 applies a power, and mainboard 31 is upwards flipped open air outlet 71, and wind is got rid of from air outlet, is air-flow outflow direction as shown by arrows in FIG..Lug 5 pairs of mainboards 31 play a position-limiting action, and when mainboard is upwards turned to maximum angle, contact above mainboard top edge and lug, air outlet is opened to maximum.
Electric controlled door iron plate is bimetallic material, and namely adopt at least 2 kinds of metal synthesis, this thermal coefficient of expansion of two kinds is different, and warmer internal temperature is high, then bimetal leaf bends little, and the ventilating opening that turnover door is opened is also little; The low then bimetal leaf of warmer internal temperature is bending large, and the ventilating opening that turnover door is opened is large.
Bimetal leaf 4 adopts segmentation structure, the bending of multistage one forms, between first paragraph 41 and second segment 42, bending angle is β, between second segment 42 and the 3rd section 43, bending angle is α, first paragraph 41 is connected with output switch 2, produce a pressure to subplate when stretching to subplate 32 for the 3rd section 43 and bend, after heated bending, the 3rd section 43 of bimetal leaf is contacted by flange 431 with subplate, and flange 431 is arc preferably.
First paragraph 41 and output switch 2 by adjust bolt with spacer 6 removably connects, convenient maintenance and replacement when being convenient to sheet metal damage, be also convenient to control sheet metal be heated after a degree of crook.3rd section with second segment angle α optimized angle for being more than or equal to 120 °, second segment and first paragraph angle β angle are preferably 90 °.
