Description

Domestic fully automatic temp. controlled electric boiler

The utility model national uses the technical field of heating boiler.

Existing civilian heating boiler all is to be fuel with the coal, is medium with water or oil, direct heating or through the heat exchange mode of heat supply again.The family that generally adopt in the north small-sized recirculated water boiler of warming oneself, a family one stove, each heating phase consumption coal be on average at the 3-5 ton, the disbursement height, and it is insufficient burn, and caloric value is little, and the indoor and outdoor atmosphere pollution is serious, increase labour intensity, the resident much feels disadvantageous.

The purpose of this utility model is that designing a kind of is the energy with the electricity, by the boiler of electric hot water heating, to overcome many drawbacks that coal fired boiler exists.

Design of the present utility model is, formed by housing, body of heater, temperature-controlled cabinet, control box and support, housing surrounds rectangular shape by iron sheet, in housing, top is body of heater, is rectangular shape, and the bottom is a temperature-controlled cabinet, control box in that a side setting of housing is opened the door is equipped with thermometer, indicator lamp.Whole housing is by stent support.

The upper end that electrothermal tube, body of heater are installed in body of heater is provided with outlet pipe, and there are return pipe and dewatering orifice in the lower end of body of heater.

The copperhead of U-shaped electrothermal tube is fastened on the furnace body outer wall by nut in the body of heater, with the outer wall insulation, stretches out binding post, by temperature detect switch (TDS), is connected to power supply.

Temperature detect switch (TDS) is made of one group of temperature controller interchange contact and stacked switch, also controls one group of red green indicator lamp simultaneously.

When the utility model is installed in heating system, the outlet pipe of body of heater and return pipe are connected with system pipeline respectively, seal the dewatering orifice, fill with water toward boiler heating system again,, connect the 220V power supply the temperature controller design temperature, the bright demonstration of green light is heated, and water temperature raises in the boiler, and heating system is carried out hot water circuit, system water temperature raises, water is heated again in the boiler, directly causes to reach design temperature, and temperature controller drives the contactor action, electrothermal tube is stopped power supply in the bright demonstration of the red light of cutting off the electricity supply, body of heater.Water temperature decline is 5-10 ℃ in boiler, and temperature controller drives contactor switches on the electrothermal tube in the body of heater, and red light goes out, and green light is bright, and water temperature continues to raise in the body of heater, and break-make continues heat supply to heating system so repeatedly.

The utility model is realized automatic heat supply, has saved manpower, does not have environmental pollution, and is simple in structure, produces easily, and cost is low, is suitable for family and uses.
