Abstract

A pump-free electric water circulator comprises a heating tank body, a sealing cover, outlet and return pipes and a heating plate electrode, which is characterized in that: the upper end of the heating plate electrode is fixedly arranged on the sealing cover of the heating tank body, and a distance is reserved between the lower end of the heating plate electrode and the inner bottom of the heating tank body; the sealing cover of the heating tank body is arranged with the outlet and return pipes and a pressure relief nozzle, the outlet and return pipes are connected to the bottom of the bank body, and the lower ends of the outlet and return pipes are lower than that of the heating plate electrode. The utility model has the advantages of safe and reliable operation without water and electricity leakage faults; automatic water return, simplified structure, low cost and not easily being damaged without noise during operation, which is extensively applicable to both the household electric warmers with low power and high-power electric boilers.

Description

No pump electric hot water circulator

Technical field

The utility model relates to a kind of life warming installation, particularly a kind of no pump electric hot water circulator.

Background technology

At present, household warming such as electric blanket, electric heater directly adopt heating wire or electrothermal tube to make thermal source, and be very dangerous, and improper use causes fire easily, and current field is to human body generation effect in using simultaneously, and mouth parched and tongue scorched is uncomfortable easily.For this reason, the applicant has developed a kind of " noiseless battery lead plate heat hot water circulator " (patent No. 01113944.7), has safe in utilization, comfortable, little power consumption, low cost and other advantages, find to remain in following deficiency by using: the leak current fault that leaks appears in mounting structure under electrode adopts; Rely on the breaker device backwater, cause complex structure, cost height, damage easily, sound is arranged during work, can not be suitable for the large power, electrically boiler and use, the scope of application is little.

The utility model content

The purpose of this utility model provides a kind of no pump electric hot water circulator, does not have the leak current fault that leaks, and is safe and reliable; Automatically backwater, designs simplification, cost are low, be not easy to damage, voiceless sound during work, applied widely.

The purpose of this utility model is achieved by the following technical solution: it comprises heating tank body, seal cover, water outlet return pipe, heating electrode plates, it is characterized in that: the heating electrode plates upper end fixedly is assembled on the seal cover of heating tank body, the lower end of heating electrode plates is provided with distance with heating tank body inner bottom surface, on the seal cover of heating tank body water outlet return pipe and pressure release mouth are set, the water outlet return pipe passes to tank base, and its lower end is lower than the heating electrode plates lower end.

Above-mentioned pressure release mouth top is a cecum, has relief hole on the sidewall, and the suit pressure limiting discharges gum cover on the pressure release mouth.

The lower end of above-mentioned heating electrode plates is no less than 2mm with the distance that heating tank body inner bottom surface is provided with.

The utility model has the advantages that: there is not the leak current fault that leaks, safe and reliable; Automatically backwater, designs simplification, cost are low, are not easy to damage, and voiceless sound during work not only is suitable for low power family expenses space heater, also is suitable for the large power, electrically boiler and uses, and is applied widely.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a pressure release mouth structure schematic diagram.

Fig. 3 is that the utility model connects radiator, water tank schematic diagram.

The specific embodiment

See Fig. 1,2, concrete structure of the present utility model is as follows: heating tank body 2 assembling seal covers 5, heating electrode plates 1 upper end fixedly is assembled on the seal cover 5 of heating tank body, the lower end of heating electrode plates 1 is provided with the distance that is no less than 2mm with heating tank body 2 inner bottom surfaces, on the seal cover 5 of heating tank body water outlet return pipe 3 and pressure release mouth 6 are set, water outlet return pipe 3 passes to tank base, and its lower end is lower than the lower end of heating electrode 1 plate.Pressure release mouth 6 can adopt traditional relief valve, also can adopt following structure: the top of pressure release mouth 6 is a cecum, has relief hole 6-3 on the sidewall 6-2, and the suit pressure limiting discharges gum cover 6-1 on the pressure release mouth 6.

See Fig. 3, by water outlet return pipe 3 serial connection radiators 9, water tank 10, water tank 10 is provided with exhaust outlet 11 with the utility model.Radiator 9 is low power family expenses space heater, powerful electric boiler etc.

Operation principle; Water outlet return pipe 3 of the present utility model is connected radiator 9, radiator 9 connects water tank 10 by return pipe, heating electrode plates 1 in the heating tank body 2 adds hot water, water heats up and produces vapour pressure, the water surface in the vapour pressure effect tank body, water enters radiator 9 from heating tank body 2 by water outlet return pipe 3, enters into water tank 10 from radiator 9.After water level in the heating tank body 2 was lower than heating electrode plates 1, heating stopped.Cooling back heating tank body 2 produces negative pressure, and the water in the water tank 10 is in radiator 9 is drawn back heating tank body 2, and heat cycles so repeatedly once more.In heating tank body 2 during the vapour pressure superpressure, pressure release mouth 6 releasing pressure automaticallies, assurance work safety.
