Abstract

The utility model relates to an electric circulating hot water heater for heating, which belongs to the technical field of heating. The utility model is composed of a box body loading heated water and containing an electric heating device, an electric heating device which is composed of an electric heating pipe and a heat conduction sheet, a water temperature control switch, a water level positioning valve, a pressure limiting safety valve, a heating temperature selection circuit and an operation button or key. The utility model has the advantages of high energy conversion efficiency and good economy. Through actual use comparison, a power consuming expense is close to the expense of coal; thereby, the utility model has the advantages of small size, sanitation, stable operation, convenience and labour saving.

Description

Heating circulating hot water electric heater

Technical field

The utility model belongs to the heat supply process field, is specifically related to the heater of water.

Background technology

Single household is the heating service mode independently, and is still very general now, and most coal stove heat cycles water that has water jacket that adopts, and is sent to the radiator heat radiation in room.The heater of this heating agent, thermal conversion efficiency is low, wastes energy, and environmental pollution is heavier, frequent coal, draws ash, relates to the carrying of coal and lime-ash again, and the manpower work of input is more.Once the domestic heating system that occurred combustion gas heat cycles water in the last few years is because of safety and cost problem fail to obtain to promote.In addition, the household electricity warmer that also has form to differ, but all be the space that the heat that heating produces directly is dispersed into the room, do not form the system that carries distribute heat through heating agent, the heat radiation scope is little, and energy utilization rate is low, and heat cost is big.

Summary of the invention

The purpose of this utility model provides a kind of heating circulating hot water electric heater, overcomes the above-mentioned shortcoming that existing family independence heating installation exists.

The utility model is heated water by loading and holds the casing of electric heating heater, the electric heater unit that electrothermal tube and heat exchange sheet are formed, and water temperature control switch, the water level normal valve, pressure-limiting safety valve, heating-up temperature selects circuit and control knob or key to form.There is the filler casing upper end, and an end of casing has circulating water intake, and the other end has circulating water outlet.The assembled relation of each parts is that electrothermal tube is embedded in the heat exchange sheet, and electric heater unit is fixed on bottom in the casing, and the water level normal valve is installed in the casing internal upper part, and the temp control switch probe is installed in the interior position a little less than the water level normal valve of casing.Power switch and temperature are adjusted circuit and are installed in the outer side of casing.

Good effect of the present utility model is the energy conversion efficiency height, good economy performance.Use relatively through reality, when outdoor daily mean temperature-15 ℃, give area 100m ²The ordinary residence heat supply, keep indoor 18-22 ℃, mouthful power consumption 12KW approaches the expense with coal, thereby makes little, the clean health of its volume, stable, the labour-saving advantage of saving worry have practical significance.

The specific embodiment

To give construction area 100m ²The ordinary residence heat supply be example, make the casing 1 of the high 700mm of the wide 120mm of long 800mm by existing processing technology of metallic plate.For preventing that casing from adding the water distortion, welding arm-tie 2 with holes in the casing.There is filler 3 the casing upper end, and the pressure-limiting safety valve 4 of the similar pressure cooker use that is connected with the filler spiral is arranged on the filler.The circulating water intake 5 of casing one end bottom is one section pipeline that is welded on casing one end.The circulating water outlet 6 of the other end is for to pass tank wall from lower box, and the upper end is near the pipeline of the water surface.Electrothermal tube 7 selects 2 of power 0.5KW, 1 of 1KW, the low power powerful diameter 180mm ring-type that curves of the about 150mm of diameter that curves.With casting in respectively after the Sn-Al alloy material fusing outside the electrothermal tube that outer and 0.5KW of a 0.5KW electrothermal tube and 1KW combine, form two heat exchange sheets 8.Tin accounts for the 10-30% of alloy gross weight in the Sn-Al alloy.Heat exchange sheet is installed in bottom in the casing, and the heat exchange sheet that contains two electrothermal tubes is installed in recirculated water water inlet one side.Extracting power supply cord, is installed in apart from 80mm position, casing upper end as water level normal valve 9 with less tap.Temperature detect switch (TDS) 10 is chosen the approved product of 60-70 ℃ of control temperature in the market, be installed in below the casing internal upper part water surface.In a side of casing outer circulation water inlet power switch and temperature selection circuit and control knob or key 11 are installed, temperature selects circuit and control knob or key can select the temperature adjusting switch of other existing household electrical appliance such as electric oven for use.Below promptly finish the making of circulating hot water electric heater.The recirculated water inlet tube and outlet tube is connected the pipeline that leads to fin, and water circulating pump is installed on pipeline.Back out the safety valve of electric heater upper end, open the water level normal valve, in the fin that electric heater reaches with it is communicated with, add water, when the water level normal valve there are flowing out, stop to add water, the safety valve of screwing on, close the water level normal valve, connect heater and pump power, set heating-up temperature, the utility model use that promptly puts into operation.

Claims

1, heating circulating hot water electric heater, it is characterized in that: be heated water and the casing (1) that holds the electric heating heater by loading, the electric heater unit that electrothermal tube (7) and heat exchange sheet (8) are formed, water temperature control switch (10), water level normal valve (9), pressure-limiting safety valve (4), heating-up temperature selects circuit and control knob or key (11) to form, there is filler (3) the casing upper end, one end of casing has circulating water intake (5), the other end has circulating water outlet (6), the assembled relation of each parts is that electrothermal tube is embedded in the heat exchange sheet, electric heater unit is fixed on bottom in the casing, and the water level normal valve is installed in the casing internal upper part, and the temp control switch probe is installed in the interior position a little less than the water level normal valve of casing.Power switch and temperature are adjusted circuit and are installed on the outer end face of casing.
