Description
Technical field
The present invention relates to the thermostat technical field, particularly relate to a kind of thermostat with notching construction leading truck.
Background technology
Along with the continuous reinforcement of awareness of safety, more and more pay attention to the overtemperature protection of various electric heating products.At present; What mainly adopt is the bimetal leaf Kick type temperature controller; Its operation principle is: by the butterfly bimetal leaf back reversal deformation that is heated, promote push rod (push rod be cover be through in the centre bore of leading truck do directed moving), promoted the moving contact reed of its connection again by push rod; Realize moving contact and the break-make of deciding contact, reach the effect of temperature control.The leading truck that uses at present is except that centre bore, and remainder is an entity structure, adopts the temperature-sensitive reaction speed of thermostat of this structure directing frame slow; The temperature-sensitive accuracy is low, needs usually to wait for the long heat absorption time, and thermostat just can carry out the kick action; Make the environment temperature of electric heating products be higher than the temperature that thermostat is controlled; The temperature control weak effect, even can threaten the fail safe of electric heating products, cause security incident.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of thermostat with notching construction leading truck, can promote the reaction sensitivity of thermostat and the accuracy of temperature control, and guarantees to use the security of products of this thermostat, reaches energy-saving effect.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of thermostat with notching construction leading truck is provided; Comprise: shell, leading truck, push rod, temperature-sensitive sensor and capping, the inside of said leading truck have hot-fluid exchange groove, and its peripheral plane place has equally distributed miniature counterbore; Said hot-fluid exchange groove is symmetricly set in the interstitial hole both sides of said leading truck; Said push rod passes the interstitial hole of said leading truck, and is arranged at deciding between contact and moving contact and the said temperature-sensitive sensor in the said outer shell cavity, and said capping is sheathed on the outside of said shell.
In preferred embodiment of the present invention, said temperature-sensitive sensor is the bimetallic disk.
In preferred embodiment of the present invention, said leading truck is ceramic leading truck.
The invention has the beneficial effects as follows: the present invention has disclosed a kind of thermostat with notching construction leading truck; Through the hot-fluid exchange groove maximization that leading truck is inner; To reduce the volume of part itself, try one's best heat transferred with pyrotoxin to the bimetallic disk, and reduced of the absorption of other peripheral parts heat; Make the temperature-sensitive of this thermostat correct, reaction fast.Thereby guaranteed to use the safety of products of thermostat of the present invention, also reached energy-conservation effect.
Description of drawings
Fig. 1 is the structural representation that the present invention has thermostat one preferred embodiment of notching construction leading truck;
Fig. 2 is the structural representation of leading truck shown in Figure 1;
The mark of each parts is following in the accompanying drawing: 1, shell, 2, leading truck, 21, hot-fluid exchange groove, 22, miniature counterbore, 23, interstitial hole, 3, push rod, 4, the temperature-sensitive sensor, 5, capping.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1 and Fig. 2, the embodiment of the invention comprises:
A kind of thermostat with notching construction leading truck; Comprise: shell 1, leading truck 2, push rod 3, temperature-sensitive sensor 4 and capping 5; The inside of said leading truck 2 has hot-fluid exchange groove 21; Its peripheral plane place has equally distributed miniature counterbore 22, and said hot-fluid exchange groove 21 is symmetricly set in the both sides of the interstitial hole 23 of said leading truck, and said push rod 3 passes the interstitial hole 23 of said leading truck 2; And it is be arranged at deciding between contact (figure does not show) and moving contact (figure does not show) and the said temperature-sensitive sensor 4 in said shell 1 chamber, and then capping 5 cover sealing are fixed.
Wherein, said temperature-sensitive sensor 4 is the bimetallic disk.Because the thermal coefficient of expansion of each constituent element layer is different, when temperature changed, the deformation of active layers was greater than the deformation of passive layer, thereby the integral body of bimetallic disk will be bent to passive layer one lateral bending, made it touch push rod 3.Push rod 3 contacts again decides contact and moving contact in shell 1 chamber, makes it reach the effect of temperature control.
Said leading truck 2 is ceramic leading truck, has high temperature resistant, corrosion resistant characteristic.
The present invention is under the situation that guarantees part strength; Leading truck 2 inner hot-fluid exchange grooves 21 are maximized; To reduce the volume of part itself, this notching construction makes the part volume reduce 86 mm
to the full extent.Can reach following purpose: the one, reduced the ratio that this part bimetallic disk from thermostat itself absorbs heat; The 2nd, extraneous thermal source because of the part volume is little, and only need obtain less heat in conduction, and more heat then can pass to the bimetallic disk; The 3rd, because leading truck fluting area is bigger, the heat of thermostat shell hardware then is more conducive to focus on the bimetallic disk with the mode of thermal convection.
Thermostat of the present invention offers 8 miniature counterbores 22 at the peripheral plane place of hot-fluid exchange groove 21; Reduced contacting of bimetal leaf and ceramic leading truck; Thereby reduce the heat conduction loss of bimetallic disk and ceramic leading truck, the gap of miniature counterbore 22 has also strengthened the acceleration of thermal convection simultaneously.
The present invention has disclosed a kind of thermostat with notching construction leading truck; Through the hot-fluid exchange groove maximization that leading truck is inner; To reduce the volume of part itself; As far as possible with the heat transferred of pyrotoxin to the bimetallic disk, and reduced of the absorption of other peripheral parts, thereby promoted the reaction sensitivity of thermostat and the accuracy of temperature control heat.With 150 ℃ thermostats is example; Be set in surface temperature and be on 200 ℃ the heating plate and do test, the product that is assembled by common leading truck is 30s from being put into heating plate to operate time of thermostat, and be 25s the operate time that the present invention has the thermostat of notching construction leading truck; Counterpart terminal product programming rate calculates with 10 ℃/s; Then can the temperature of control be reduced by 50 ℃, thereby guarantee the safety of end product, also reach energy-conservation effect.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
