Abstract
The utility model relates to a dry combustion proof electric water boiler, comprising a body shell and a heating component. The heating component is stabilized at the underside of the body shell. One part of the underside of the body shell extends inward to shape a hollowness which is provided with a piece of magnetic and fixedly connects with the float through a connecting rod. A pair of contacts is arranged inside the body shell, and a spring on one of the contact is provided with another piece of magnetic. The pair of the contacts is in series with the electricity supply circuit of the heating component. The utility model can prevent the dry combustion from occurring as well as the burning out of the water when there is no one available.
Description
Technical field
The utility model relates to electric heater unit, is specifically related to a kind of anti-dry boiler, belongs to International Classification of Patents H05B electroheat technology field.
Background technology
The electric water boiler of Fast Heating has been widely used among the daily life, because its convenient and practical characteristics and extremely people's favor is commonly called as immersion heater.But, to answer the electrical appliance as all, also there is the problem of the security control that eliminates safe hidden trouble in electric water boiler, and particularly prevents the problem of anhydrous dry combustion method.The energising of boiler is controlled by the direct open-close on-off of user with outage is general, therefore in case run into lack of water or when cutting off the water supply, just be unfavorable for the safe handling of this water heater.In the prior art, for addressing this problem, the design of blowing a whistle and reporting to the police is arranged, the effect of informing is played in the warning though it can be blown a whistle, and can't solve the dry combustion method problem, still has potential safety hazard when unmanned guard.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of anti-dry boiler that can effectively prevent the dry combustion method phenomenon is provided.
The purpose of this utility model is achieved through the following technical solutions.
A kind of anti-dry immersion heater comprises housing and heating element heater, and heating element heater is fixed on the housing bottom surface.The part of the housing bottom surface formation cavity that extends internally, first magnetic patch is positioned at cavity and is fixed on the float by connecting rod; Pair of contact is housed in the housing, is fixed with second magnetic patch on the reed of one of them contact, lower part of frame is equipped with interface.Above-mentioned pair of contact is serially connected in the current supply circuit of heating element heater.
The utility model since magnetic patch respectively with the interlock of contact and float design, only make that when water level acquired a certain degree, the contact could be connected.Thereby prevented from effectively water to be dryouied the phenomenon that causes accident and anhydrous dry combustion method when unattended.
Description of drawings
Accompanying drawing is the overall structure schematic diagram of the utility model anti-dry boiler.
Among the figure: 1, housing, 2, elastic spring, 3, power line, 4, clip, 5, cavity, 6, magnetic patch, 7, steam vent, 8, heating element heater, 9, interface, 10, float, 11, connecting rod, 12, magnetic patch, 13, cushion block, 14, insulation board, 15, pair of contact.
The specific embodiment
As shown in drawings, the anti-dry boiler comprises housing 1 and heating element heater 8, and heating element heater 8 is fixed on the bottom surface of housing 1.Interface 9 is housed on the housing 1, like this, can be closely connected with the hot water bottleneck.Too high for preventing the thermos bottle internal pressure, a side of housing has steam vent 7, so that the gas in the bottle is partly discharged.
The part of housing 1 bottom surface extends internally and forms cavity 5, and magnetic patch 6 is set in the cavity 5, and magnetic patch 6 is fixed on the float 10 by connecting rod 11, along with float 10 moves up and down.Magnetic patch 6 also can move up and down in cavity.Pair of contact 15 also is housed in the housing 1, and contact 15 is serially connected in the current supply circuit of heating element heater 8.One of them contact is a fixed contact, is contained on the insulation board 14 by cushion block 13, and insulation board 14 is fixed in the housing.Simultaneously, fixed contact links to each other with clip 4, with the convenient power line 3 that connects.Also be fixed with elastic spring 2 on the insulation board 14, another magnetic patch 12 is housed in the end of elastic spring 2.Another contact also is contained on the elastic spring, and relative with the contact on being contained in cushion block.When float 10 moves up and down, drive magnetic patch 6 and move up and down, thereby make, fixed contact separately or contact.
When anhydrous or water level was not enough, float was sagging naturally, magnetic patch 6 and magnetic patch 12 toward each other, magnetic patch 12 is subjected to the attraction of magnetic patch 6, overcomes the resistance of reed, pair of contact 15 is separated from each other, heating element heater 8 dead electricity.When water filled up, magnetic patch 6 misplace each other with magnetic patch 12, and because of the effect of reed elastic force contacts with each other pair of contact 15, heating element heater 8 must.
