Description
Technical field
The present invention relates to a kind of automatic convection type powder heat accumulation electric heater, mainly can be used for heating residential.
Background technology
Electric heater is of a great variety at present, and particularly the coal at the city one-storey house changes in the electric process, and for eliminating the atmosphere pollution that fire coal causes, the resident warms oneself generally all should change the electric heater heating into.The electric heater pattern is various in the market, electric heating installation using oil as medium is arranged, the far infrared electric heater, the halide torch electric heater, the convection type electric heater, glassed steel electric heater etc., wherein electric heating installation using oil as medium has the not available advantage of other pattern electric heater, it comprises by the continuous successively fin in a row of multi-disc, front shroud and electrothermal tube, the two ends up and down of described fin are equipped with or form the extended hollow adapter sleeve of along continuous straight runs, the inside of described hollow adapter sleeve is formed with oil through, oil through on each sheet of described fin is connected, described electrothermal tube is positioned at the oil through that described hollow adapter sleeve is connected, described front shroud is connected with the file leader of described fin, thus when electrothermal tube energising heat production, heat is transferred on the fin by heat transfer medium oil, pass in the surrounding space by fin then, realize the purpose of heating room air.The defective of this electric heater is not have heat accumulation function, the electric energy when being unfavorable for making full use of low power consumption.
Because power consumption is in all variations of generating period every day, the power department of China is in order to improve power consumption efficiency at present, encourage consumer's electricity consumption when electricity consumption " paddy " as far as possible, not electricity consumption when electricity consumption " peak ", low when having put into effect " paddy " with electricity price, when " peak " with the high policy of electricity price, under this policy, exploitation energy-storage type electric heater, electric energy when not only helping making full use of low ebb, give full play to the utilization rate of electrical of electrical network, but also brought practical economic interests to the user, reduce the heating cost.
Summary of the invention
For overcoming the above-mentioned defective of prior art, the invention provides a kind of automatic convection type powder heat accumulation electric heater, the heat production of can when low power consumption, switching on of this electric heater, and when peak of power consumption, these heats are come out, be used to heat room air, to regulate the electricity consumption periodicity of electrical network, peak clipping Pinggu, save electric power resource, and reduce the heating cost.
The present invention realizes that the technical scheme of above-mentioned purpose is: a kind of automatic convection type powder heat accumulation electric heater, comprise shell, electrothermal tube and accumulation of heat powder, be provided with diaphragm plate up and down in the described housing, described accumulation of heat powder is filled in the described space between the diaphragm plate up and down, the heating part of described electrothermal tube is positioned at and is inserted in described accumulation of heat powder, described case top is provided with shutter, the bottom is provided with down shutter, the described diaphragm plate of going up is with leaving the space that constitutes collection chamber between the described case top, described diaphragm plate down is connected with the some wireways that are communicated with described collection chamber and all press the chamber with leaving the space that formation is all pressed the chamber between the described shell body bottom shell on the described diaphragm plate up and down.
Operation principle of the present invention is: when power supply is trough, give electric heater energising of the present invention, the electrothermal tube energising is conducted heat, heat is transmitted on the accumulation of heat powder, temperature on the accumulation of heat powder raises, accumulate heat, when electrical network is the electricity consumption crest, turn off the power supply of electric heater, avoid electricity consumption when peak of power consumption, when needs heating room air, shutter up and down, to the upper reaches, air enters all to press from shutter down and passes on the accumulation of heat powder interconnective through hole behind the chamber to the upper reaches according to the hot gas in the collection chamber, through the through hole on the accumulation of heat powder time, heated by the accumulation of heat powder, enter collection chamber then, flow out from collection chamber again and enter the interior space, formed thus gas around with electric heater in convection current, bring the heat of accumulation of heat powder storage in the electric heater into room air continuously, the temperature of room air is raise.
Relative with the when other forms of accumulated electric heater of existing common electrical warmer, electric heater of the present invention is free to select electricity consumption time and heating time, and the electric weight when making full use of low ebb has improved the operational efficiency of electrical network thus, has reduced electric cost; Because the free convection that its main radiating mode is an air-flow does not need the extraneous power that replenishes, and can dispel the heat when the electrical network peak of power consumption.
