Abstract
The utility model relates to an anti-dry-combustion electric heating hose, which belongs to an electric heating element. The existing electric heating hose has a fatal defect that the liquid is used as heating medium; when used under an abnormal condition, the existing electric heating hose can generate the condition of dry combustion; the existing electric heating hose can burn out or explode in short time, which can bring inconvenience for users. The purpose of the utility model is to provide an anti-dry-combustion electric heating hose. A temperature controller is arranged in the utility model and the function, the appearance and the dimension of the existing electric heating hose are not changed. When the phenomenon of dry combustion occurs, the power supply can be quickly cut off; the utility model can effectively prevent the electric heating hose being damaged. The utility model has the advantages of simple structure and low cost.
Description
It is the electric heating element of heat medium, especially anti-dry electrothermal tube with liquid that the utility model relates to a kind of.
At present existing is the electrothermal tube of heat medium with liquid, electrothermal tube all must be immersed in institute's heated liquid or the special-purpose wet goods in the course of the work.But this class electrothermal tube all has a fatal shortcoming, and when it used under abnormal condition, when promptly dry-fire condition occurring, the electrothermal tube damage of will blowing even explode in short tens seconds to a few minutes was made troubles to the user.In order to address this problem, mostly be to monitor liquid level and control power supply at the peripheral control circuit that increases of electrothermal tube, electrothermal tube damages when avoiding improper user mode to occur, circuit more complicated, cost height.
The purpose of this utility model provides a kind of anti-dry electrothermal tube, and temperature controller is housed in electrothermal tube, does not change the function and the apparent size of electrothermal tube, and deenergization promptly when dry-fire condition occurring prevents that electrothermal tube from damaging, and reaches the effect of anti-dry combustion method.
The technical solution of the utility model is: this anti-dry electrothermal tube is made up of electrothermal tube protecting pipe, inserts, heating wire, binding post etc., it is characterized in that being serially connected with on the heating wire in electrothermal tube miniature bi-metal temperature controller.
Accompanying drawing is the structural representation of a kind of embodiment of the present utility model.Among the figure: 1 electrothermal tube protecting pipe, 2 inserts, 3 heating wire, 4 temperature controllers, 5 power supply terminals.(cut two kinds of connections that two places represent temperature controller among the figure open, only connect a temperature controller during enforcement in each electrothermal tube)
Below in conjunction with accompanying drawing the utility model is further described.
This anti-dry electrothermal tube is made up of electrothermal tube protecting pipe (1), inserts (2), heating wire (3), power supply terminal (5) etc., it is characterized in that being serially connected with in the heating wire in electrothermal tube temperature controller (4).This temperature controller can be selected miniature bi-metal temperature controller for use, according to the lead-in wire mode of temperature controller, two kinds of modes of connection as shown in drawings can be arranged.When abnormal states such as dry combustion method appear in this electrothermal tube in use; the temperature of electrothermal tube will sharply rise, and when temperature rose to certain value, temperature controller disconnects cut off the electricity supply; thereby avoided the various adverse consequencess that cause therefrom, also reduced unnecessary peripheral auxiliary protection circuit.
The present utility model person is normally closed with the miniature contact that Jiangsu Baoying Electrical Apparatus Plant produces, the type that automatically resets bi-metal temperature controller is implemented the utility model, on probation through inside, it uses normal current below 10 amperes, contact action when temperature reaches 205 ℃ in the electrothermal tube tube core, control precision ± 5 ℃.Boil water with this electrothermal tube, occur after the dry-fire condition can cutting off circuit in 20 seconds, protected electrothermal tube to be unlikely damage effectively.Reduce to just often when the electrothermal tube die temperature, contact automatically resets.Temperature controller can be serially connected in the middle end that also can be connected on heating wire of heating wire.
This electrothermal tube structure is simple, and cost is low, does not change former electrothermal tube dimensions, applied range.
