Abstract
The utility model provides an automatic electricity interruption device with an anti-dry burning function for electric heating water boiling appliances (such as an electric kettle). The automatic electricity interruption device with an anti-dry burning function is characterized in that the automatic electricity interruption device with an anti-dry burning function is used as one support point of an electric heating water boiling appliance, and a certain water level segment of the electric heating water boiling appliance is set by the attraction force change of the attraction or non attraction of a permanent magnet and a fixing plate. When water is higher than the water level segment, electrical contacts are communicated. When the water is lower than the water level segment which is set, the electrical contacts are instantly disconnected by a mechanism under the action of a spring to realize an automatic powering off function. The utility model has simple structure and reliable work.
Description
The utility model is a kind of anti-dry auto switching electric installation of electrothermal water boiling utensil.
Existing electrothermal water boiling utensil, as: insulating pot on the one hand, causes because of water evaporation dry combustion method if in time deenergization was whole after water was opened; On the other hand, also may be because of unexpected direct anhydrous dry combustion method, its result can cause electrical equipment to damage, even leads to a disaster.
The purpose of this utility model is to provide a kind of auto switching electric installation that can make the electrothermal water boiling utensil have the anti-dry function.
This device mainly by pedestal 3, retainer 12, shell 10, decide frame 1, decide plate 2, permanent magnet 4, isolating frame 6, push rod 9, spring 11 and moving contact 7, static contact 8 etc. form.It is characterized in that deciding Jia 1 constitutes affixed with permanent magnet 4, isolating frame 6, moving contact 7, static contact 8; Pedestal 3, retainer 12, decide plate 2 and shell 10 and constitute affixed; Decide frame 1 and be a supporting-point of electrothermal water boiling utensil; The integral body of deciding formations such as the integral body of formations such as frame 1 and pedestal 3 is acted on by respectively at spring 11 two ends, and can relatively move as upper and lower limit.
Accompanying drawing one is the structural representation of this device.
The purpose of this utility model is achieved in that sets a certain upper water level of electric water heating, when When being higher than on this water level, be a supporting-point because deciding frame 1, relatively static, spring 11 pressurizeds, decide plate 2, The integral body of the formations such as pedestal 3 will move down because of gravity, until lower limit at this moment, is decided plate 2 and permanent magnet 4 adhesives, power turn-on. If water level is reduced until when being lower than the lower water level of setting because of unexpected, heavy Power will be relieved to the suction that is enough to that spring 11 is overcome and decides 4 of plate 2 and permanent magnets, like this, and at spring Under 11 the effect, deciding plate 2 and permanent magnet 4 can not adhesive, decides plate 2, pedestal 3, retainer 12 and The integral body of the formations such as shell 10 returns to rapidly the upper limit, drives on the push rod 9 to move, and makes moving contact 7 and quiet Contact 8 moments disconnection realizes power down function.
Below in conjunction with accompanying drawing one and embodiment the utility model is specified.
Make this device decide frame 1 and be a supporting-point of insulating pot, integral body and insulating pot that retainer 12 and pedestal 3 etc. constitute are affixed.When insulating pot injects water, and when exceeding the last water level (as: horizontal plane exceeds electrothermal tube 30mm) of setting, decide plate 2 will because of spring 11 pressurizeds until lower limit, at this moment, decide plate 2 and permanent magnet 4 adhesives, the contact conducting.If the people is at the scene, timely deenergization after water is opened.If the people is not at the scene, timely deenergization, because of the water evaporation drops to below the following water level (as: horizontal plane exceeds electrothermal tube 10mm) of setting water level eventually, at this moment, gravity will be relieved to the suction-combining force that is enough to that spring 11 is overcome and decides between plate 2 and the permanent magnet 4, make rapidly and decide to move in the time of the upper limit on plate 2 grades, drive on the push rod 9 to push away, make moving contact 7, static contact 8 moments disengagement, realize power down function.Obviously, when insulating pot was anhydrous, as long as insulating pot is in the free state that no external force presses down, power supply can conducting.
Claims (2)
1, a kind of anti-dry auto switching electric installation of electrothermal water boiling utensil, this device mainly by pedestal 3, retainer 12, shell 10, decide frame 1, decide plate 2, permanent magnet 4, isolating frame 6, push rod 9, spring 11 and moving contact 7, static contact 8 etc. form, and it is characterized in that deciding Jia 1 and permanent magnet 4, isolating frame 6, moving contact 7, static contact 8 formations are affixed; Pedestal 3, retainer 12, decide plate 2 and shell 10 and constitute affixed; Decide frame 1 and be a supporting-point of electrothermal water boiling utensil; The integral body of deciding formations such as the integral body of formations such as frame 1 and pedestal 3 is acted on by respectively at spring 11 two ends, and can relatively move as upper and lower limit.
2, according to right 1 described device, power turn-on when it is characterized in that permanent magnet 4 and deciding plate 2 adhesives.
