Abstract
The utility model relates to a dry heating avoiding temp. controller, which is composed of a machine base, a cover plate, a push rod, a capsule, etc. The utility model is characterized in that the upper end of the push rod penetrates through the middle bore of the cover plate, the lower end of the push rod is supported by the capsule plate of the capsule, and the spring tab is contacted with the push rod which can move up and down. When the capsule is heated and expanded, the capsule plate forms a salient circular arc shape. The utility model has the advantages that the temperature controller is unable to automatically reset, only can be manually reset after examining the reason. The dry heating avoiding device is mainly provided with an electric water heater.
Description
The utility model relates to temperature control equipment.
At present, temperature controller mostly is A.T.C greatly, when the heating medium temperature is higher than the control temperature later on regard to automatic cutout,, continue to heat in case control the just automatic later on energized of temperature when the heating medium temperature is lower than, but, in case control malfunctioningly automatically, or the wearing and tearing of some part of temperature controller usually can not auto power off, can produce the dry combustion method phenomenon, electric heater is burnt.For this reason, an anti-dry heating temperature controller to be installed in the device of well heater.
The purpose of this utility model provides the temperature controller that a kind of anti-dry is used.
Technical scheme for achieving the above object, its main composition is that cover plate is fixed on the support, push rod is arranged in the middle of support, spring leaf, static contact are fixed in the support, fixedly connected with bellows below the support, it is characterized in that passing the middle hole of cover plate on the push rod, the lower end heads on the bellows sheet on the bellows, spring leaf contacts with push rod, and push rod can move up and down; During bellows expanded by heating pressure, the bellows sheet is protruding garden arc.
Principle of the present utility model is to produce pressure the bellows sheet is under pressure after temperature-sensing element is heated, the pressure that produces is upwards heaved the bellows sheet to be protruding garden arc, and with the push rod jack-up that makes progress, original spring leaf contacts with static contact, and the circuit that makes well heater is connected heating, at this moment, the jack-up because push rod makes progress, spring leaf and static contact are disconnected, the electric heater circuit is disconnected, because the bellows sheet is protruding garden arc, so, after the heating medium temperature was lower than the control temperature, the bellows sheet can not restore automatically, at this moment, have only by push rod just being made the reinstatement of bellows sheet to pressing down with manual mode, and spring leaf is contacted with static contact and make electric heater connect circuit, here, adopting manual mode mainly is to reach when controlling temperature when dry heating temperature controller, necessarily there are various faults to occur, so, could restore with manual mode after must fixing a breakdown, to reach the purpose that prevents dry combustion method.
Below in conjunction with drawings and Examples the utility model is done detailed explanation.
Fig. 1 is the anti-dry heating temperature controller front view.
Fig. 2 is the anti-dry heating temperature controller right view.
Referring to Fig. 1, Fig. 2, go up with screw (13) cover plate (9) is fixing at support (12), post hole, a garden is arranged in the middle of the cover plate (9), one nut (8) is arranged on the cover plate (9), face shield (11) is threaded with cover plate (9), with rivet (7) that 2 shell fragment riveting pin (6) are fixing in support (12), 2 shell fragment riveting pin (6) are fixed on the support (12) with rivet with 2 spring leafs (4) again, equally, with rivet 2 static contacts (5) are fixed on the support (12), with screw that bellows (14) is fixing below support (12), bellows (14) is tightly connected by bellows shell (1) and bellows sheet (2), and bellows (14) is communicated with temperature-sensing element with tubule, cruciform push rod (10) is in support (12), the post hole, garden in the cover plate (9) is passed in the upper end, and the lower end contacts with bellows sheet (2), contacts with spring leaf (4) on middle both sides.
After temperature-sensing element is heated, the generation pressure that expands is upspring the bellows sheet (2) in the bellows (14), push rod (10) is moved up, and, spring leaf (4) and static contact (5) are disconnected, thereby the heating element circuit is disconnected spring leaf (4) jack-up, the process of hand-reset is that face shield (11) is outwarded winding, make mould sheet (2) recover the origin-location yet depress push rod (10), spring leaf (4) is contacted with static contact (5), the heating element circuit is connected.The utility model is mainly used on all kinds of utensils of electrical heating, particularly is applied on the electric heater.
