Description

Domestic electric kettle

The utility model relates to electric heater unit, is the temperature-controlling mechanism that uses in a kind of electric heater unit; The Detection ﹠ Controling technology that also relates to temperature.

Raising day by day along with living standards of the people, and the attenuating gradually of the abundance of supply of electric power and electricity price, people use the situation of electrical appliance more and more general, heat up water etc. normally with coal or gas as original people, and use people cleaner, insulating pot faster also more and more now, because electricity consumption heats up water comparatively fast, how to make people can find in time water boiled or in time when water is boiled deenergization just become people and urgently want the practical problem that solves.Certainly, had some at present insulating pot is carried out the design of temperature control, but all there is such or such problem in these existing designs, be that a power-off protection apparatus with the weight saving effect of kettle is housed as present most typical attemperating unit; Utilize water to become behind the steam weight and lighten and cause the outage control action, this will inevitably produce the sensitivity problem of control, and the reliability of work is low, the control effect is bad, and after outage, remove the non-artificial water that adds, otherwise switch can not close, so can not realize heat insulation function.

The purpose of this utility model provides a kind of simple in structure, temperature control effect good, reliability is high, the temperature control part is cheap Domestic electric kettle.

Technical solution of the present utility model is: a kind of Domestic electric kettle, and kettle body, pot lid are arranged and carry hand, heating element heater is housed in the kettle, it is characterized in that: the kettle base is housed at the bottom of the kettle, the paraffin attemperating unit is housed in the kettle base.

The paraffin attemperating unit that is equipped with in the kettle base described in the utility model comprises the temperature control assembly that is contained near the kettle bottom, and and the joining dead man assembly of temperature control assembly.Certainly, also can adopt other suitable version.

Dead man assembly described in the utility model comprises the base that is connected with kettle base madial wall, screw rod as bearing pin is housed in the base, dead man is contained on the screw rod, the live wire of one termination alternating current of screw rod, the other end of dead man contacts with fixed contact on being loaded on kettle base madial wall or throws off, and fixed contact is connected with heating element heater.Certainly, also can adopt other suitable version.

Temperature control assembly described in the utility model comprises a paraffin container, the top of the cavity of paraffin container is filled with paraffin, and piston is equipped with in the paraffin below, is connected with guide rod under the piston, the middle part of lower end of the guide rod and dead man links, and between the bottom interior wall of piston and paraffin container spring is housed.Certainly, also can adopt other suitable version.

The utility model has the advantages that: modern design is reasonable, simple in structure, cheap, temperature control effect is good, stable and reliable for performance.

Below in conjunction with drawings and Examples the utility model is further described:

Fig. 1 is the structural representation of a kind of Domestic electric kettle of the present utility model;

Fig. 2 is the structural representation of the temperature control assembly that adopted in the utility model;

Fig. 3 is the structural representation of the dead man assembly that adopted in the utility model.

Fig. 1 has described an embodiment of the present utility model.In this embodiment, kettle body 3, pot lid 2 are arranged and carry hand 1, heating element heater (as heating wire) 4 is housed in the kettle body 1, kettle base 6 is equipped with in kettle body 3 bottoms, and the paraffin attemperating unit is housed in the kettle base 6.The paraffin attemperating unit that is equipped with in the kettle base 6 comprises the temperature control assembly 5 that is contained near the kettle bottom, and and temperature control assembly 5 joining dead man assemblies 7.Kettle base 6 also is connected to power line 8, and fixed contact 10 also is housed in the kettle base 6, and the kettle base is stamped lower bottom cover 96 times.

Fig. 2 has described the temperature control assembly, it comprises a paraffin container 21, the top of the cavity of paraffin container 21 is filled with paraffin 22, piston 23 is equipped with in paraffin 22 belows, piston is connected with guide rod 24 23 times, the middle part of guide rod 24 lower ends and dead man 33 links, and between the bottom interior wall of piston 23 and paraffin container 21 spring 25 is housed.The cavity of paraffin container 21 has four (or other suitable numbers) small embossments 26, has top dead centre when making piston 23 by spring 25 compressions.

Fig. 3 has described the dead man assembly, it comprises the base 31 that is connected with kettle base 6 madial walls, screw rod 32 as bearing pin is housed in the base 31, dead man 33 is contained on the screw rod 32, the live wire of one termination alternating current of screw rod 32, the other end of dead man 33 contacts with fixed contact 10 on being loaded on kettle base 6 madial walls or throws off, and fixed contact 10 is connected with heating element heater 4.Also have pad 34, nut 35 etc. among the figure.

The course of work of the foregoing description is: after connecting power supply, at the beginning, spring 25 in the temperature control assembly 5 is being pressed piston 23, piston 23 guide rod 24 of ining succession, guide rod 24 is held dead man 33, at this moment dead man 33 left end contacts contact with fixed contact 10, resistance wire heating element 4 work this moment, when water temperature raises, paraffin container 21 in the temperature control assembly 5 passes to paraffin 22 with heat, paraffin 22 expanded by heating, because water temperature does not reach the minimum holding temperature that is made at the beginning, therefore at the beginning paraffin 22 melt back volume increases only be for be full of and piston 23 between the space, when paraffin 22 just arrives small embossment 26, water temperature reaches minimum holding temperature (as 95 ℃), from this moment, piston 23 is headed on by paraffin 22 and begins to move down, because the middle part of in the groove of guide rod 24 lower ends dead man 33 being housed, when water temperature raise gradually, piston 23 began to move downward, dead man 33 only is suspended in guide rod 24 grooves, the contact is not separated, when water temperature continuation rising, when reaching 100 ℃, dead man begins to move down, just dead man 33 separates with fixed contact 10 foremost, and power supply is cut off, and insulating pot just enters keeping warm mode, along with water temperature descends, the volume of the paraffin 22 on the piston 23 reduces, and spring 25 is pressing piston 23 to move upward, and dead man 33 is unsettled once more, when water temperature is reduced to 95 ℃ of minimum holding temperatures, piston 23 will be forced into topmost, and dead man 33 moves up under the effect of guide rod 24, and the front end of dead man 33 is contacted with fixed contact 10 again, power supply is switched on, and so circulation repeatedly.
