Abstract
The utility model relates to an anti-creeping electric water heater, which consists of a case, an upper clamping plate, an upper electrode sleeve, electric heating pipes, a lower clamping plate, an upper grounding electrode, a grounding terminal, a water inlet grounding electrode, a water outlet grounding electrode and the like, wherein the electric heating pipes are respectively inserted and arranged on each electrode seat of the upper electrode sleeve and the lower electrode sleeve, the lower clamping plate is arranged at the outer side of the lower electrode sleeve, the upper grounding electrode is arranged on the lower clamping plate, the grounding terminal is arranged on the lower clamping plate and is connected with the upper grounding electrode, the water inlet grounding electrode is arranged at a water inlet, and is connected with the grounding terminal, and the water outlet grounding electrode is arranged at a water outlet and is connected with the grounding terminal. Because the electric heating pipes are made of quartz pipes or high-temperature resistance ceramic materials, and a mode of coating electric heating films on the outer surfaces is adopted for electricity conduction, the electric heating pipes are difficult to crack. The upper grounding electrode is arranged on the lower clamping plate, and current can be fast grounded when the seepage or pipe crack occurs. The grounding electrodes are respectively arranged at the water inlet and the water outlet, so the water heater is safer and more reliable.
Description
Technical field
The utility model relates to a kind of water heater, specifically a kind of anticreep electric heater.
Background technology
Relevant by retrieval patent documentation does not retrieve a kind of anticreep electric heater identical with the utility model structure at present as yet.Existing electric heater kind is more, differs from one another.Electric heating film water heater is because it has good security, so be subjected to people's popular welcome.Because electric heating film water heater has good safe, energy-conservation, characteristics such as firing rate is fast, thermal efficiency height; so looked at by the parent of wide variety of user institute; but also only protect outward with one deck plastic protective layer owing to its heating tube; the heating back is because the rising of temperature; be prone to the displacement between heating tube and the supporting plate seal; produce seepage; when serious because heating tube heats up very fast; cause the heating tube explosion; thereby the potential safety hazard of existing; so be necessary existing electric heater is improved, to improve the performance of product better.
Summary of the invention
The purpose of this utility model is that a kind of improvement on existing electric heating film water heater basis will be provided, and has good seal performance, safe and reliable a kind of anticreep electric heater.
Technical characterictic of the present utility model is: considering safety, reliably on the basis, be designed to by shell, train wheel bridge, the top electrode cover, electrothermal tube, the bottom electrode cover, lower plate, last earth electrode, ground terminal, control assembly, the water inlet earth electrode, a kind of anticreep electric heater that the delivery port earth electrode is formed, the top electrode cover, be fitted with electrothermal tube respectively on each electrode tip holder of bottom electrode cover, put at top electrode and to be provided with train wheel bridge, the outside at the bottom electrode cover is provided with lower plate, be provided with earth electrode on the lower plate, described ground terminal is arranged on the lower plate, and is connected with last earth electrode; The water inlet earth electrode is arranged on the water inlet, and is connected with ground terminal; The delivery port earth electrode is arranged on the delivery port place, and is connected with ground terminal.
Described electrothermal tube is quartz glass tube or resistant to elevated temperatures ceramic material, and outer surface is coated with the heating body of Electric radiant Heating Film.
The described earth electrode of going up is and the contacted electric conductor of heating tube.
Described water inlet earth electrode is the earth conductor of a multi-through hole.
Described delivery port earth electrode is a lead-through conductors that is connected with ground terminal.
During work, water enters from the water inlet tube head, and heats by pipe through electrothermal tube, is flowed out by effluent pipe mouth again, and when electrothermal tube generation seepage and booster, the water that leaks out contacts with last earth electrode, and ground terminal is drawn electric current and carried out ground connection; Except by earth electrode electric leakage being shunted, the delivery port earth electrode also is connected with ground terminal when booster occurring, makes to guarantee no current by the current of delivery port outflow.
The utility model has the advantages that: because electrothermal tube adopts quartz ampoule or resistant to elevated temperatures ceramic material, the mode that outer surface is coated with Electric radiant Heating Film is conducted electricity, and is difficult for booster thereby electrothermal tube is heated evenly; Owing to be provided with earth electrode on the lower plate, electric current is very fast to be incorporated into ground terminal by last earth electrode thereby make when seepage and booster occurring, and carries out ground connection by ground terminal; Owing to be provided with earth electrode respectively at the water inlet and the delivery port place of lower plate, carry out ground connection on the ground terminal thereby when electric leakage appears in the water that flows out the delivery port place, can be incorporated into by earth electrode rapidly, make water heater more safe and reliable; Because rational in infrastructure, performance good, safe and reliable, so very big practical and popularizing value is arranged.
