Abstract

The invention discloses an automatic reset temperature controller, which comprises a sealed induction system and a signal power transmitting system, wherein the sealed induction system consists of a corrugated pipe, a capillary tube, a progressive wheel, a micro switch and the like. The automatic reset temperature controller is characterized in that: a lug boss is formed on the inner wall of a switch box of the micro switch, the lug boss corresponds to a contact, and the height of the lug boss relative to the inner wall of the switch box is 1.2+/-0.05 millimeter. Because the lug boss is directly formed on the inner wall of the switch box of the micro switch, the automatic reset temperature controller has a simple structure and a few components, reduces the cost, solves the problem of troublesome screw adjustment, effectively avoids the problem of loosening due to the adoption of a screw, and ensures the precision of temperature control.

Description

The type that automatically resets temperature controller

Technical field

The present invention relates to a kind of temperature controller, especially relate to the type that the automatically resets temperature controller that a kind of household electrical appliance are used, belong to robot brain tool technical field.

Background technology

Fig. 1 is the structural representation one of the sensitive switch of the traditional type that automatically resets temperature controller; Fig. 2 is the structural representation two of the sensitive switch of the traditional type that automatically resets temperature controller; Fig. 3 is the overall structure schematic diagram of the traditional type that automatically resets temperature controller.

As shown in Figure 1 to Figure 3: present household electrical appliance, great majority have adopted temperature controller to control the operating state of household electrical appliance, and the used in the market type that automatically resets temperature controller, distance between the contact of its sensitive switch 1 is to regulate by manual adjustments screw 2, and then carry out temperature controlled, after soon screw 2 will be adjusted to suitable position, and then 2 glue of screw are fixed, this kind switch control temperature mode, complex process not only, and needed parts are a lot, and cost is also very high, and it is loosening easily to be used for thermoregulator screw 2, thereby causes the problem of temperature control effect difference.

Summary of the invention

In order to overcome the deficiencies in the prior art, the object of the present invention is to provide that a kind of technology is simple, cost is low, and the temperature control type temperature controller that automatically resets accurately

The present invention is achieved through the following technical solutions:

A kind of type temperature controller that automatically resets, comprise bellows, capillary, progressively take turns, the sealing induction system of composition such as sensitive switch and pass on the system of signal power, it is characterized in that, be formed with a boss on the inner wall of the switch enclosure of described sensitive switch, its described boss is corresponding with the contact.

Above-mentioned boss is 1.2 ± 0.05mm with respect to the height of the inside wall of switch enclosure.

The invention has the beneficial effects as follows: the present invention is by directly forming boss on the switch enclosure inwall of sensitive switch, it is not only simple in structure, the use parts are few, reduced cost, overcome screw and regulated the problem that bothers, and effectively avoided producing loosening problem because adopt screw, guaranteed temperature controlled precision.

Embodiment

Below in conjunction with accompanying drawing, describe the specific embodiment of the present invention in detail:

As shown in Figure 4: the type that automatically resets temperature controller, comprise cover plate 14, the seal cavity that shell 11 and base plate cover 16 form, the sealing induction system that capillary 7 and bellows 6 form, and master arm 5, location-plate 8, portable plate 12, perpendicular extension spring 9, horizontal extension spring 10, push rod 4 and sensitive switch form passes on the system of signal power, also comprise setting camshaft 13 and progressive 15 knob assemblies that form of taking turns on the cover board simultaneously, wherein camshaft 13 is hinged on the cover plate 14, progressively take turns 15 and be fixed on the camshaft 13, and the upper surface of itself and portable plate 12 interacts, the upper end of perpendicular extension spring 9 is fixed on the left side of portable plate 12, its lower end is fixed on the location-plate 8, location-plate 8 and master arm 5 are hinged on respectively on the front-back of shell 11, and the transverse arm of master arm 5 is pressed on the upper surface of bellows 6, the inboard of its vertical arm then links to each other with an end of horizontal extension spring 10, the other end of horizontal extension spring 10 is fixed on the shell 14, and on the outside of above-mentioned master arm 5 vertical arms, also be connected with push rod 4, push rod 4 is plugged in the sensitive switch 1, and sensitive switch 1 then is connected the right side of shell 14.

In addition, on the inner wall of the switch enclosure of sensitive switch 1, be formed with a boss 3, its described boss 3 is corresponding with the contact, and boss 3 is 1.2 ± 0.05mm with respect to the height of the inside wall of switch enclosure, by the mode of boss 3 is set, makes sensitive switch 1 structure of the present invention become simply, at needs screw 2 is not set, thereby a lot of material costs have been saved, and the structure of boss 3 is fixed, and promptly the distance of contact is certain, has guaranteed the temperature control of quality effectively.

The course of work of the present invention is: capillary 7 sense temperature change, when the temperature of capillary 7 perception is higher than set point, temperature sensing agent gas in capillary 7 and the bellows 6 expands, bellows 6 elongations, its vertical arm that promotes master arm 5 moves right, shell fragment in the push rod 4 pushing tow sensitive switches, it is contacted with the contact, form and be communicated with, carry out temperature control, when temperature is lower than set point, the temperature sensing agent contraction of gas in capillary 7 and the bellows 6, bellows 6 shrinks, under the reset response of horizontal extension spring 10 and perpendicular extension spring 9, shell fragment and contact disconnect, in this process, and recessed wheel shaft 13 and progressive elastic force scope of taking turns the perpendicular extension spring 9 on the 15 knob assembly control portable plates 12 that form.

Below disclose the present invention with preferred embodiment, so it is not in order to restriction the present invention, and all employings are equal to replaces or technical scheme that the equivalent transformation mode is obtained, all drops within protection scope of the present invention.
