Abstract
The utility model discloses a duplicate protections electric heating kettle, which is composed of a pot body, a pot lid, a switching push-button, a heater, a handle, a steam lead and a protecting controlling circuit. The electric heating kettle also comprises a water level inductor capable of contacting with the liquid. The water level inductor is arranged on the bottom of the pot body. The vapor temperature sensor positioned on the outside of the pot body and the protecting controlling circuit are respectively and electrically connected with the water level inductor and steam temperature sensor. By adopting the foregoing technical proposal, the utility model realizes the duplicate protections of the jug, and breaks the past unsafe forms of the direct passage of current by the power switch button and the dependence on overheat controller to break the power of the bygone jug, and can thoroughly avoid the happen of the dry combustion. The utility model provides the users with an electric heating kettle with safety, reliability and long service life.
Description
Technical field
The utility model relates to a kind of electric kettle, particularly a kind of electric kettle with duplicate protection.
Background technology
The electric kettle of selling on the present market, thereby all be to adopt the power switch button of pressing on the kettle directly to make the heater energising work of kettle make the water in the kettle boiled, so in fact kettle exists serious potential safety hazard, when the user forgets pouring to the kettle the inside, can be because the overheated generation that causes fire of heater.Though the kettle that has was equipped with heat controller, as application number is that the BP of GB2339088 has disclosed a kind of cordless electrothermal kettle that bimetal leaf is crossed heat controller that has, its lead-in connector comprises a moulded plastic body, there are two heating element heater overtemperture control devices and lead-in connector to make an integral body, each overtemperture control device all respectively has the bimetal release action piece, the bimetal release action piece is supported on the spring metal support, its operation principle is when not having water to exist in the kettle, the main temperature distortion that relies on bimetal leaf, the electric contact that is in contact with one another is separated, thereby circuit is disconnected, and heater just quits work.But above-mentioned bimetal leaf is crossed heat controller and is also existed significant disadvantages, reason is that operation principle that bimetal leaf is crossed heat controller is to reach after the temperature of bimetal leaf work distortion heater dry combustion method a period of time to cut off the electricity supply heater is quit work, but can cause the kettle body deformability in the time of the heater dry combustion method, for the plastics kettle, the appearance of situation such as also can cause ageing of plastics, variable color, leak, and the life-span of heater also can shorten greatly.
The utility model content
In order to overcome the above-mentioned defective of prior art, the utility model provides a kind of electric kettle with duplicate protection.
The technical scheme that the utility model adopted is: a kind of electric kettle with duplicate protection; comprise kettle body, pot lid, shift knob, heater, handle, steam lead, protection control circuit composition; this electric kettle also comprises the water level sensor that is contained in the kettle body inner bottom part that can contact with liquid; the steam temperature detector of kettle external body, described protection control circuit are electrically connected with water level sensor, steam temperature detector respectively.
Described steam temperature detector is positioned at the steam (vapor) outlet end or the arrival end of steam lead.
Described steam lead is positioned at handle or kettle body.
Described protection control circuit is fixed in the bottom or handle of kettle body.
After adopting above technical scheme; have only the water logging in kettle not have water level sensor; water level sensor passes to the protection control circuit to water level signal; the work of protection control circuit instruction heater; water is opened the temperature of back by steam temperature detector induction steam; temperature signal is passed to the protection control circuit; protection control circuit instruction heater quits work; kettle is carried out duplicate protection; broken through the dangerous form that kettle single use power switch button is in the past directly switched on and relied on the heat controller outage; thoroughly solve the generation of dry combustion method, thus bring to the user a kind of safe and reliable, the electric kettle of long service life.
Description of drawings
Fig. 1 is a kind of front view with electric kettle of duplicate protection of the utility model;
Fig. 2 is the cutaway view of Fig. 1.
The specific embodiment
As shown in Figure 1, electric kettle of the present utility model is made up of kettle body 1, pot lid 2, shift knob 3, handle 4, pedestal 5, and pedestal 5 and kettle body 1 are reached electric connection by electric connector, thus kettle body 1 relatively pedestal 5 realize that 360 degree rotate.
Shown in the cutaway view as shown in Figure 2, protection control circuit 10 can be fixed in the bottom 14 of handle 4 or kettle body 1, and present embodiment preferably is fixed on protection control circuit 10 on the bottom 14 of kettle body 1; Water level sensor 11 is contained in kettle body 1 inner bottom part that can contact with liquid; Kettle body 1 outer bottom is fixed a heater 12; Steam lead 41 can be installed in kettle body 1 or the handle 4, and present embodiment preferably is installed in steam lead 41 in the handle 4; The steam inlet end of steam lead 41 is positioned on the pot lid 2, and its steam (vapor) outlet end is positioned on the bottom 14; Steam temperature detector 13 can be arranged on the steam inlet end or the port of export of steam lead 41; present embodiment preferably is arranged on the steam (vapor) outlet end of steam lead 41 to steam temperature detector 13 and is fixed on the bottom 14 of kettle body 1; bottom 14 covers the bottom of kettle body 1, and protection control circuit 10 is electrically connected with water level sensor 11, steam temperature detector 13 respectively.
When not having water in the electric kettle; although electric kettle places on the pedestal 5; press shift knob 3; because electric kettle does not have water to exist; water level sensor 11 is not worked; there is not signal to pass to protection control circuit 10; then protect control circuit 10 can not instruct heater 12 to work; thereby realize the dry combustion method protection; have only electric kettle to have water to exist, and water level sensor 11 do not had by water logging, water level sensor 11 just can be worked; water level signal is passed to protection control circuit 10,12 work of protection control circuit 10 instruction heaters.After water is boiled; the steam inlet end of the steam lead 41 of the water vapour that produces from the pot lid 2 enters steam lead 41; after steam brings out from the steam (vapor) outlet of steam lead 41; steam temperature detector 13 is started working; vapor (steam) temperature is detected; temperature signal is passed to protection control circuit 10; protection control circuit 10 is made comparisons detected temperature signal and default temperature; when detected temperature is higher than default temperature; protection control circuit 10 just instructs heater 12 to quit work, and realizes power-off protection.
