The utility model relates to heating equipment for the resident in winter, in particular to a household electric heater with an automatic temperature control; the prior heating equipment for the resident in winter, in the northern part of Chinese, mainly adopts a coal-fired boiler, and the hot water is circulated and transmitted to the user. While, with the increase of the price of the coal and the decrease of the price of the electricity, the electro heating which can be the trend of the future can not pollute the environment. The utility model is a household electric heater with automatic temperature control; the electric heating apparatus comprises two box-shaped electric heaters arranging on the lower end of the heat transfer pipeline and the radiator sheet, and the box-shaped electric heaters shares the same cavity with the heat transfer pipeline and the radiator sheet. The circuit and the heat transfer controller are arranged on the heat transfer pipeline, a travel switch which can be droved by the steam is arranged on the circuit and the heat transfer controller. The utility model which is a household electric heater with the automatic temperature control is easy to use, and is energy-saving, without pollution and noise.

Description

Temperature automatically controlled family's electric heater

Background technology:

The utility model relates to a kind of resident's warming equipment, is a kind of temperature automatically controlled family's electric heater specifically.

Technical background:

At present, in northern China, resident's warming equipment mainly adopts coal fired boiler with hot water circuit heat to be passed to the user, but along with the price of coal in China constantly increases, civilian electricity price reduces, and the electricity consumption heating will be following trend; And adopt the electricity heating also can not pollute to environment.

Summary of the invention:

That the purpose of this utility model is to provide is easy to use, pollution-free, noiselessness and energy-conservation temperature automatically controlled family's electric heater.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of temperature automatically controlled family's electric heater, comprise electric heater unit, heat transfer tube road, fin, medium and power switch, its special character is: described electric heater unit 1 is by two box-like electric heaters 4,5, it is positioned at heat transfer tube road 2 and fin 6 lower ends, and with its in same cavity; Circuit and hot transmission control unit 3 are set on heat transfer tube road 2.

The travel switch that above-mentioned circuit and hot transmission control unit 3 can promote for steam.

Above-mentioned box-like electric heater 4,5 is made of outer box, resistive heater and quartz sand, and resistive heater and quartz sand are arranged in the outer box.

On the output steam mouth in above-mentioned heat transfer tube road 2 miniature blower fan is set.

The utility model is with respect to prior art, and its advantage is as follows:

Electric heater unit of the present utility model is made of two box-like electric heaters, and it can use the box-like electric heater of different heating as required, thereby the power and energy saving.

The utility model is in light weight, can arbitrarily dismantle, pollution-free, noiselessness, when not using, and the erosion of incrustation scale to heating system avoided in the draining of can exitting.

Fig. 1 is an external form overall structure schematic diagram of the present utility model;

Fig. 2 is the cross-sectional view of the utility model control chamber;

Fig. 3 is circuit theory diagrams of the present utility model;

The specific embodiment:

Major part boiler heating system in winter is that water is converted into water vapour at present, along the circulation of defeated heating coil road, heat is supplied with the user.Referring to Fig. 1, Fig. 2, the utility model has been done some changes on original warmer basis.It adopts electrothermal method, and thermal source and user's heating place is tightly linked to each other, and electric calorifie installation is arranged on the radiator, and circuit and hot transmission control unit are set on the heat transfer tube road.The utility model water, burns heat to water and becomes water vapour under the effect of heater as heat transfer agent, steam is flowed in fin and pipeline mutually, emit heat after, steam becomes the steam of water or lower temperature, be back to heating chamber heating, circulation and so forth by pipeline; When steam temperature was too high, circuit and hot transmission control unit are set on the heat transfer tube road will gauge tap, is heated device and is arranged on low temperature, keeping warm mode.

Referring to Fig. 1, Fig. 2, described electric heater unit 1 is by two box-like electric heaters 4,5, and it is positioned at heat transfer tube road 2 and fin 6 lower ends, and with its in same cavity; It is the box-like electric heater 5 of insulation for 4, one of the box-like electric heaters of heating that 4,5, one of two box-like electric heater are housed in electric heater unit 1; Be that because quartz sand (silica) is non-conductive, and ratio of specific heat is low by the heating wire of quartz sand parcel in the box-like electric heater, temperature can raise rapidly, also can descend rapidly, saves a lot of heats, is contained in the line box to strengthening heating surface area.When heating, it becomes the water heating into steam, upwards is evaporated to the required heat circulation of user.The temperature of heating heating wire can maintain between 600 ℃-1000 ℃; Another insulation heating wire is for continuing heating, and its temperature thereby can be saved electricity consumption between 150 ℃-300 ℃.

Referring to Fig. 2, Fig. 2 is the cross-sectional view of the utility model control chamber;

Circuit and hot transmission control unit 3 are set, the travel switch that circuit and hot transmission control unit 3 can promote for steam on heat transfer tube road 2.Be the selector switch of heating system, selector switch of the present utility model is by an air bag, axis that is connected with air bag and spring leaf constitute, and the steam pressure of this switch and heating system the inside is related, when the inside pressure reaches certain value, air bag is by the moving axis motion of pressure zone, drive the spring leaf motion that is connected with power supply simultaneously, like this, just can be with the heating wire cut-off who is heating, and with another the insulation heating wire is connected, thereby reach the saving electricity consumption purpose; Referring to Fig. 3, Fig. 3 is the circuit diagram of circuit selector switch; Selector switch can connect different heating wire by switch.

During use, electric heater unit is connected with power supply, water is heated to be water vapour, water vapour flows in heat transfer tube road and fin, brings the user with heat; When the heating system internal gas pressure increased to certain value, air bag was compressed, and the axial advancement in the middle of making is moving, spring leaf and heating binding post was separated, even the electric current in the heating heating wire disconnects; Since during the effect of spring and air bag makes with move forward by continuing, another spring leaf and insulation binding post are contacted, promptly be incubated heating wire and switch at this moment; Calculate according to pressure, air bag generally reaches 1.15 standard atmospheric pressures when air pressure inside, and air bag begins to change, and when reaching 1.5 standard atmospheric pressures, axis is released forward, makes the heating heating wire cut-off, to the contact of insulation heating wire switch.

For water vapour is better flowed in heat transfer tube road 2 and fin 6, miniature blower fan is set in heat transfer tube road 2, can accelerate water vapour under the drive of blower fan flows ducted, thereby make the hot steam in each radiator can obtain the circulation renewal, the hot steam on the heating system is in time flowed to output channel.

When steam flows in the thermal output pipeline, heat is transmitted out, turning cold afterwards or reducing temperature becomes water, flowing back to from pipeline, gets back to initial heating heating wire place, can be heated to be steam once more and circulate in pipeline.
