Embodiment Construction
[0015] The present invention will be further described below in conjunction with accompanying drawing:
[0016] The heating tube is a water and electricity isolated insulated heating tube, which has great selectivity. In the present invention, glass-ceramics or ceramics are preferred.
[0017] One end of the heating tube is closed. The electrothermal film is plated on the inner surface of the heating pipe, and an electric electrode is arranged at the nozzle end of the heating pipe.
[0018] The electrodes connected to the electrothermal film can be either positive or negative, AC or DC, and the voltage can be any value between 3 and 400V.
[0019] The melting point of the power-connecting electrode is lower than the maximum working temperature of the electrothermal film, in order to ensure the safety and reliability of the power-connecting electrode.
[0020] The lower end of the connected electrode is also provided with a surrounding buffer insulation belt. The insulation b...

The invention relates to an instant type electric heating tap which comprises a heating tube and a control panel. An electric heating film layer is coated on an inner surface of the heating tube, and electric heating film connecting electrodes are disposed on the mouth of the heating tube. An insulation strip winding the heating tube for a loop is disposed at the lower end of the electric heating film connecting electrodes, the distance between the insulation strip and the connecting electrodes is 1-2cm, and a conductive bar is disposed between the heating film and the connecting electrodes. The electric heating film connecting electrodes are the same, without positive electrode and negative electrode, both alternative current and direct current can be connected with the connecting electrodes, and voltage is within the range of 300-400v. A part of the electric heating film which is coated on the heating tube emits heat, and thus electric electrodes are connected to the heating tube safely and reliably. The heating film has the advantages that connection is firm, service life is long, a heating face is an infrared face, heat transmission is concentrated, and electric conversion efficiency is high. Further, electric heating conversion rate of the electric heating tap made of the heating film is as high as 95%, power is 1-4kw, the electric heating tap can provides hot water of 30 DEG C or so after powered on for a few seconds, and a user can use the water to wash hands or clothes. The instant type electric heating tap is energy-efficiency and energy-saving, and overall operating cost of the instant electric heating tap is lower than the prior electric heating taps.
Description
【Technical field】 [0001] The invention relates to a household electric heating appliance, in particular to a faucet using a polycrystalline semiconductor electric heating film tube as a heating element. 【Background technique】 [0002] At present, the main heating element of the known instant electric faucet is a resistance wire, and the resistance wire is a wire heating element, which has low electric-to-heat conversion efficiency and short service life, making it unsafe to use. There is an urgent need for an instant electric water faucet. 【Content of invention】 [0003] The technical problem to be solved by the present invention is: aiming at the problems of low electric-thermal conversion efficiency, short service life and unsafe use existing in the existing instant electric hot water faucet, the present invention provides an instant electric hot water faucet, which is not only electric -High thermal conversion efficiency, long life and safe use. [0004] In order to s...
