Abstract

The utility model discloses an intelligent-heating electric heating boiler. A water tank (1) is arranged at the upper part of the intelligent-heating electric heating boiler, a hot water outlet (7) is formed in one side of the water tank, an automatic vent valve is arranged at the hot water outlet, and a return pipe (2) is arranged at the lower part of the water tank; and an electric heating pipe (6) is arranged at the bottom of the water tank and connected with a temperature control and protecting device. The intelligent-heating electric heating boiler is free of noise and pollutant discharge, and is freely controllable in temperature; the heating cost is low, due to the adoption of an economic operation manner according to program control theories of heating in time-shared and segmented manners, the operation cost is lower than those of a fuel oil electric boiler, a fuel gas electric boiler and a common electric boiler, and the intelligent-heating electric heating boiler has the cost advantage after the electricity price of a rural distribution network is dropped; and the operation is safe, due to the full-automatic constant pressure design and the arrangement of a leakage protection device, an internally mounted overheat protector works sensitively, and when the internal temperature reaches 75 DEG C which is a limiting temperature, the whole system is automatically shut down, so that the intelligent-heating electric heating boiler is unnecessary to be monitored by a specified worker.

Description

The intelligent heating boilers heated electrically

Technical field the utility model relates to a kind of small heater boilers heated electrically, is a kind of Household electric boiler specifically.

Oneself the independent boiler that heats of the rural area that background technology is present or city suburbs adopts coal-fired more, there is contaminated environment in coal-burning boiler, must often fills out coal, the uppity shortcoming of temperature, along with the raising of people's living standard all has higher requirements to indoor and outdoor surroundings, particularly coal constantly appreciated in recent years, impelled people to develop high efficiency, pollution-free, manageable boilers heated electrically.

The summary of the invention the purpose of this utility model is to provide a kind of intelligent heating boilers heated electrically, and its cost is low, and is reliable, and hygienic and convenient is saved manpower.

The technical solution of the utility model is as follows:

A kind of intelligent heating boilers heated electrically, its top is water tank, and water tank one side has hot water outlet, establishes automatic exhaust steam valve at water outlet, and return pipe is established in the bottom of water tank; Electrothermal tube is established in bottom at water tank, and this pipe connects temperature control and protective device.

Above-mentioned temperature control and protective device are that power supply is through earth leakage protective device difference jointing temp controller, power supply indicator; both were in parallel with relay indicating light after thermoswitch was connected with electrothermal tube; one termination power of the thermoswitch of above-mentioned parallel connection, electrothermal tube and portable lamp, the other end accesses temperature controller through solid-state relay.

The utility model has the advantage of: but 1, electric heating equipment noiseless, non-pollutant discharge, temperature can freely control, heating time, heating cost free hold, rationally the effective use energy.2, heating cost is low, adopts way of economic operation according to heat program control principle of time sharing segment, and operating cost is all lower than fuel oil, combustion gas and common electrical boiler, after the downward modulation of rural power grids electricity price cost advantage is arranged more.3, security of operation, Automatic Control normal pressure design also have earth leakage protective device, and inner overheat protector work of installing is sensitive, when internal temperature reaches capacity temperature 75 when spending, the whole system autoshutdown.Need not the special messenger guard.Electric heating has the incomparable innate advantage of other heating systems as a kind of emerging heating system, and development prospect is very good.

Description of drawings Fig. 1 is the utility model overall schematic;

Fig. 2 is the control of the utility model temperature and protective device circuit theory diagrams.

The utility model is described in further detail below in conjunction with accompanying drawing for the specific embodiment.

Can see a kind of intelligent heating boilers heated electrically by Fig. 1～2, its top is water tank 1, and water tank one side has hot water outlet 7, establishes automatic exhaust steam valve at water outlet, and return pipe 2 is established in the bottom of water tank; Establish electrothermal tube 6 in the bottom of water tank, this pipe connects temperature control and protective device; 3 is attemperating units among the figure, the 4th, and power supply indicator, the 5th, relay indicating light.

Can see above-mentioned temperature control and protective device by Fig. 2; it is that AC power AC is through earth leakage protective device QF difference jointing temp controller WK, power supply indicator HL1; both were in parallel with relay indicating light HL2 after thermoswitch ET connected with electrothermal tube EH; one termination power of the thermoswitch of above-mentioned parallel connection, electrothermal tube and portable lamp, the other end is through solid-state relay SSR access temperature controller WK.Thermoswitch ET is a normally closed switch, and what this device was selected is 75 degree, i.e. just automatically tripping of temperature to 75 degree, stopped heating.

Above-mentioned temperature controller, select XMT-8 intelligent digital temperature controller, that the electric instrument of Yuyao City gold Co., Ltd produces, the high-performance instrument of new generation that adopts international advanced technology to develop, has timed startup/shutdown function, temperature required by the keyboard to set up room, temperature controller opens and closes automatically heating load according to established temperature, thereby reaches the purpose of regulating room temperature.
