Description

Energy-saving tubular type electric heater

The utility model relates to a kind of electric heater, belongs to the home electric technical field.

Current, the solar water heater of use, when sunshine shortage, the preference temperature that adopts the water in the heating heating storage tank to regulate water in the water heater mostly.Domestic, electric water heater also adopts the storage-type electric heating device mostly, and this series products is all big because of moisture storage capacity, the area of casing heat radiation is also big relatively, so heat time heating time is long, and the power consumption height, in addition, the electrothermal water heater generally requires to have a power failure and uses, and this brings many inconvenience to the user.

The purpose of this utility model is to remedy the deficiencies in the prior art, and a kind of Fast Heating is provided, and power consumption is few, and is simple in structure, and insulation is reliable, the energy-saving tubular type electric heater that does not have a power failure and just can use safely.

The purpose of this utility model is finished by following technical measures.

The utility model is made up of housing, inner bag, heat-insulation layer, heating, water pipe, temperature sensor, fixedly heating, water pipe in the inner bag, temperature sensor is connected on the heating, water pipe has delivery port and water inlet, it is characterized in that transformer oil is arranged in the inner bag, the red copper water pipe is immersed in the transformer oil, void layer is arranged in the inner bag, and heating and inner bag are fixed by silk nut seal inside and outside the polytetrafluoroethylene (PTFE).

Described red copper water pipe inwall has screw thread.

The utility model all is immersed in red copper water pipe and heating in the transformer oil, heat exchange is between the two carried out completely, again because of being provided with screw thread at red copper water pipe inwall, increased surface area, with compare with diameter pipeline smooth surface area with length, increase by 40%, use this water heater to have advantages such as heating is rapid, power consumption is little, the utility model adopts the inside and outside silk of polytetrafluoroethylene (PTFE) nut, heating in the sealing inner bag, make that water is isolated fully in the heating inner bag, dielectric strength 〉=100M Ω, charged safe and reliable.In inner bag, be provided with void layer, to guarantee the expansion space of the various material structures of inner bag.

The utility model by electric energy by heating heating transformer oil, the red copper water pipe that is immersed in the transformer oil is heated, the water that the red copper water pipe give to flow thermal energy transfer again makes water can be raised to about 43～46 ℃ of the temperature of setting rapidly.

The utlity model has rational in infrastructure, safe and reliable, heating rapidly, advantage such as power consumption is little.The utility model can also can be used the desirable domestic, electric water heater of hot water as life as the electrical auxiliary heater of solar water heater.

Below be description of drawings:

Fig. 1 is the utility model structure cut-away view.

Wherein: 1, housing, 2, inner bag, 3, the red copper water pipe, 4, heating, 5, transformer oil, 6, temperature sensor, 7, the inside and outside silk of polytetrafluoroethylene (PTFE) nut, 8, void layer, 9, water inlet, 10, delivery port, 11, wire hole, 12, heat-insulation layer.

The utility model is described in further detail below in conjunction with accompanying drawing:

Structure is illustrated in figures 1 and 2, inner bag 2 is housed in the shell 1, inner bladder outer wall has that transformer oil 5 and red copper water pipe 3 are arranged in heat-insulation layer 12, the inner bag, the red copper water pipe is immersed in the transformer oil, red copper water pipe inwall has the screw thread of extrusion modling, and spiral placement, red copper water pipe have water inlet 9 and delivery port 10.It is fastening with the inner bag sealing that heating 4 in the inner bag passes through the inside and outside silk of polytetrafluoroethylene (PTFE) nut 7, and void layer 8 is arranged in the inner bag, and the expansion space of the various materials of inner bag after being used for heating is to guarantee safety.Temperature sensor 6 is installed on the heating, shows and control the temperature of water, and heating is connected with circuit by wire hole 11.
