Abstract
The utility model relates to a safe electrothermal kettle which is particularly suitable for preventing the damage of the water kettle and a heating tube caused by the burning out of the water in the water kettle. The utility model is composed of a kettle body and a kettle base, wherein the bottom of the kettle body is provided with a big concentric circle electrode reed type lifting device and a small concentric circle electrode reed type lifting device. An annular groove on the outer side of the bottom of the kettle body is inserted with an annular protrusion on the kettle base to form a positioning device and an overflow water infiltration preventing device. The utility model has the advantages of high safety, convenience, practicality, power saving, etc.
Description
The utility model relates to a kind of safety electric kettle, is particularly useful for preventing being caused kettle and heat-generating pipe to damage because of Hu Shui dryouies.
Electric kettle of the prior art normally power line directly is communicated with heat-generating pipe in the kettle, and great majority lack the device that prevents that electrothermal tube and kettle from being burnt out, even if having, also is only to install a temperature controller at the bottom of kettle additional, in the hope of playing a protective role.Because temperature controller has very big hot coherence, often can not cut off circuit rapidly, electrothermal tube is the less high efficiency heater of volume in addition, in case lack of water in the kettle, very easily scaling loss electrothermal tube and kettle itself.In addition, even temperature controller can in time cut off circuit, but when temperature in the kettle is reduced to a certain degree, can connect circuit once more.When making the water-in-kettle position be lower than heat-generating pipe through repeatedly heating repeatedly, still can the scaling loss heat-generating pipe, and cause the waste of power supply.
The purpose of this utility model is to overcome the above-mentioned defective of prior art, provides a kind of can preventing effectively to be dryouied the device that damages kettle and heat-generating pipe because of Hu Shui.
The utility model is made up of electric kettle A and kettle seat B two large divisions.
Accompanying drawing 1 is a cutaway view of the present utility model.
Accompanying drawing 2 separates the shape cutaway view for kettle body of the present utility model with the kettle seat.
Accompanying drawing 3 is analysed and observe and upward view for kettle body of the present utility model bottom.
Accompanying drawing 4 is analysed and observe and upward view for circular electrode conductive plate of the present utility model.
Accompanying drawing 5 is overlooked and cutaway view for lifter plate of the present utility model.
Each several part name in the accompanying drawing is called: (1) kettle body, (2) annular groove, (3) annular convex protrusion, (4) disk, (5) conductive plate, (6) big circular electrode, (7) small circular electrode, (8) lead, (9) electric heating tube, (10) temperature controller, (11) electric kettle seat, (12) lifter plate, (13) hold-down screw, (14) location Luo bolt, (15) spring, (16) spring housing, (17) power supply through hole, (18) convex electrical contact, (19) power line.
Body of Electric Kettle (1) is made with metal, pottery or resistant to elevated temperatures plastics etc., and the kettle bottom outside has an annular groove (2).Annular groove plugs together mutually with annular convex protrusion (3) on the kettle seat during user mode, constitutes a location device and anti-overflow infiltration device.There is the disk (4) of a projection centre of annular groove.Conductive plate (5) is housed and with separated big or small two the copper circular concentric electrodes of insulation board (6), (7) on the disk.Electrode (6), (7) are connected with coolant-temperature gage controller (10) with electric heating tube (9) respectively with lead (8).
Kettle seat (11) is made with metal, pottery or resistant to elevated temperatures plastics etc.In convex annular (3) circle of kettle seat, be provided with a lifter plate moving up and down (12).Lifter plate connects a spring lowering or hoisting gear at least.The spring lowering or hoisting gear is by fixedly screw (13), location Luo bolt (14), spring (15) and spring housing (16) constitute.Lifter plate (12) passes through fixedly, and screw (13) connects location Luo select (14).Spring housing (16) fuses with kettle seat (11), and lifting location Luo bolt (14) inserts from the circular hole of spring housing (16) bottom, and cover upper spring (15) back is connected with lifter plate (12) with screw (13).Above-mentioned spring lowering or hoisting gear can be made of (being generally three) a plurality of small spring structures, and also available single large spring structure replaces.Have 2 power supply through holes (17) on lifter plate (12), the bottom of power supply through hole (17) is corresponding with two the convex electrical contacts (18) on being contained in the kettle seat, and electrical contact (18) is connected power supply by power line (19).During use the electric kettle that water (flooding heat-generating pipe) is housed is placed on the kettle seat, under the gravity effect, lifter plate (12) moves down, convex electrical contact (18) passes power supply through hole (17) and contacts with big or small circular electrode (6), (7) of kettle body bottom, makes electric heating tube (9) heating thereby connect power supply.Mention electric kettle or when the water in the electric kettle is evaporated to the safety level of in advance setting (elastic force according to spring is set), lifter plate (12) rises because of pressure reduces and breaks away from convex electrical contact (18) automatically, prevents that electrothermal tube and kettle from being dryouied the purpose of scaling loss because of water thereby reach.And when electric kettle was lifted from the kettle seat, lifter plate (12) rose automatically and covers electrical contact (18) under the effect of spring, to guarantee Electrical Safety.
The utility model can not only effectively prevent electrothermal tube because of lack of water by scaling loss, and protruding the plugging together of groove and kettle seat by Body of Electric Kettle can be avoided causing power supply short circuit because water overflows in the rear infiltration kettle seat effectively. Because when having adopted circular concentric electrode, kettle body to place on the kettle seat, but the equal plugged of any rotation of 360 °, and and kettle body traction power line not itself has advantages such as using safe, easy, practical, power saving.
Claims (3)
1, a kind of overfiring-proof electric kettle of being made up of kettle body and kettle seat is characterized in that:
A. size two concentric electrodes (6), (7) are arranged at kettle body (1) bottom;
B. the annular groove (2) of kettle body (1) bottom plugs together formation one location device and anti-overflow infiltration device with the annular convex protrusion of kettle seat (11);
C., the spring type lowering or hoisting gear that a weight change by water-in-kettle makes the kettle lifting and reaches energising and outage effect is housed on the kettle seat at least.
2,, it is characterized in that the spring type lowering or hoisting gear is by fixedly screw (13), location Luo bolt (14), spring (15) and spring housing (16) constitute according to the described overfiring-proof electric kettle of claim 1; And be connected with lifter plate (12) by fixing screw.
3, according to claim 1 and 2 described overfiring-proof electric kettles, it is characterized in that having two power supply through holes (17) on the lifter plate (12), two corresponding convex electrical contacts (18) are arranged on the kettle seat.
