Description
Technical field
The utility model relates to a kind of electrothermal water boiling cup, especially relates to a kind of water boiling cup that adopts the heating of infra-red china electric-heat film.
Background technology
At present, electrothermal water boiling cup commonly used all is to work under the alternating voltage of 220V, for long-distance bus and boats and ships etc., owing to do not possess the alternating voltage of 220V, therefore can't use this electrothermal water boiling cup, all brings a lot of inconvenience for driver and passenger.There has been the inventor to notice now, and begin to design low-voltage direct electric heating water boiling cup, this electrothermal water boiling cup generally is made up of cup, bowl cover and heater, generally adopts resistance wire or based on the PTC heater of barium titanate as the heater of the most important parts of electrothermal water boiling cup; If adopt resistance wire, resistance wire is wrapped on the cup, disperses because resistance wire distributes, and this electrothermal water boiling cup heating area is little, and thermal losses is big, and electric conversion efficiency is low, and therefore boiled one glass of water is used chronic, and the use of resistance wire is short; Also there is part electrothermal water boiling cup to adopt ptc material, adopts the electrothermal water boiling cup of ptc material also to have the low defective of electric conversion efficiency.
The utility model content
The purpose of this utility model provides a kind of low-voltage direct, the thermal efficiency is high and the direct current ceramic electrothermal film water boiling cup of energy automatic constant-temperature.
In order to solve the problems of the technologies described above, direct current ceramic electrothermal film water boiling cup of the present utility model comprises cup, its key is, electric heating piece is posted in the bottom of described cup, this electric heating piece is the infra-red china electric-heat film, is to be applied on the nonmetal basal body by the thick film paste that contains rare earth element, and forms through high temperature sintering, referring to Chinese patent 200620109905.3, " ceramic heat curler ".This conductivity ceramics Electric radiant Heating Film stable performance, the energising back produces the far infrared radiation heating, surface temperature can reach 600-700 ℃, this ceramic electrothermal film is planar heating, heat exchange area is big, so the thermal conversion efficiency height, with under the constant power, equal temperature rise is than the energy saving more of traditional electrothermal part; This ceramic electrothermal film also has positive temperature coefficient, the energy automatic heat preserving; The lower end of described electric heating piece is equipped with insulation spacer, and described electric heating piece and insulation spacer are positioned at the base of cup below.Be connected with positive and negative two leads on the described electric heating piece, this lead is drawn base and is installed in the plug outward.This direct current ceramic electrothermal film water boiling cup can be under the DC voltage of 12～36V steady operation.
The beneficial effects of the utility model are, can be in the dc low-voltage scope of 12～36V steady operation, convenient in the open air or use during long-distance travel, and use the heating of electroceramics Electric radiant Heating Film, thermal conversion efficiency height, energy saving more, and the energy automatic heat preserving, use convenient.
