Abstract
The utility model discloses a heating body of an electric water heater, which comprises a cylindrical heating water tank (3). The axial middle part of the heating water tank (3) is provided with a cylindrical heating shell (1), the center of which is a sealing hollow chamber; and heating pipes (2) are distributed in the hollow chamber of the heating shell (1) uniformly. Compared with the prior art, in the utility model, the heating water tank is internally installed with the heating shell which can cover the heating pipes completely, therefore, the heating pipes are separated with the heating water tank, and the direct contact between water and the heat pipes is avoided, thus avoiding that scale deposit is formed on the surface of the heating pipes, and improving the sealing property of the heating pipes; the heating shell can select materials with good corrosion resistance and pressure resistance, thus prolonging the service life; and as the heating pipes are not contacted with water, non-metal heating pipes which can resist dry burning can be adopted. The electric water heater has simple structure, convenient operation and good using effect.
Description
Technical field
The utility model relates to a kind of electric heater unit, especially a kind of electric heater.
Background technology
At present, water heater is that bathing electrical equipment, particularly electric heater commonly used during people live is a kind of of the most normal use.Present electric heater mainly is to rely on electric heating body to heat, and common electric heating body mainly contains three kinds: immersion stainless steel calandria, quartz glass tubular type calandria and cast aluminium calandria.Immersion stainless steel calandria is to encase insulating barrier and METAL HEATING PROCESS silk with stainless steel (or red copper) shell, and its shortcoming is the easy scaling in the surface of stainless steel casing, influences the efficiency of heating surface, and fears dry combustion method; Quartz glass tubular type calandria is to adopt in quartz ampoule surface plating one deck Electric radiant Heating Film, water flows through from quartz ampoule and obtains heating, because this heating tube need install a plurality of seals, cause sealing property to descend after the long-term work easily, thereby cause and leak and bring potential safety hazard; The cast aluminium calandria adopts two aluminum alloy sheets with the heating wire heating, places a killinite sheet in the centre and insulate, and water is circulated from the water channel in the middle of the aluminum alloy sheet, so its resistance to pressure and corrosion-resistant, and long-term work is corroded easily and leaked.
The utility model content
The purpose of this utility model is: a kind of electric heater is provided, and its heating tube can be avoided producing incrustation scale on the surface, and resistance to pressure is good, can be effectively anticorrosive, and good airproof performance, be not afraid of dry combustion method, to overcome the deficiencies in the prior art.
The utility model is achieved in that and comprises columniform heating water tank, it is characterized in that: be provided with columniform heating shell at the axial middle part of heating water tank, center at the heating shell is a closed cavity, is provided with equally distributed heating tube in the cavity of heating shell.
Heating tube is straight tube or U-shaped pipe.
Heating tube is nonmetal heating tube.
Owing to adopted technique scheme, compared with prior art, the utility model adopts the heating shell that heating tube can be covered fully is installed in heating water tank, heating tube and heating water tank are isolated, avoid water directly to contact with heating tube, thereby avoided producing incrustation scale on the heating tube surface, and improved sealing property to heating tube, the heating shell can be selected corrosion resistance and the good material of resistance to pressure, can increase service life, and, therefore can adopt the nonmetal heating tube of not being afraid of dry combustion method because heating tube does not contact with water.The utility model is simple in structure, and is easy to operate, and result of use is good.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment
Embodiment of the present utility model: the structure of the calandria of electric heater as shown in Figure 1, make a columniform heating water tank 3, at the axial middle part of heating water tank 3 two ends are installed and pass the heating shell 1 of heating water tank 3, heating shell 1 center is an airtight cavity, equally distributedly in the cavity of heating shell 1 installs the heating tube 2 (heating tube 2 can be made as straight tube or U-shaped pipe) that quartz ampoule is made.
Heating shell 1 is installed in the axial middle part of heating water tank 3, makes the container of a loop configuration of inside formation of heating water tank 3, and heating shell 1 can contact by water abundant and in the heating water tank 3, can increase heating surface (area) (HS, improves firing rate; And owing to adopted nonmetallic materials as heating tube 2, therefore heating tube 2 can not damage because of dry combustion method, and because heating tube 2 does not directly contact with water, has therefore avoided the problem of surperficial generation incrustation scale, can not only effectively keep its efficiency of heating surface, and can avoid heating tube 2 to break; The corrosion resistance of heating tube 2 requires also not high, makes selection range increase greatly, independently heats the anti-pressure ability that shell 1 can improve calandria, can be useful in the heating water tank of big volume.
Claims (3)
1. electric heater, comprise columniform heating water tank (3), it is characterized in that: be provided with columniform heating shell (1) at the axial middle part of heating water tank (3), center at heating shell (1) is a closed cavity, is provided with equally distributed heating tube (2) in the cavity of heating shell (1).
2. electric heater according to claim 1, it is characterized in that: heating tube (2) is straight tube or U-shaped pipe.
3. electric heater according to claim 1 is characterized in that: heating tube (2) is nonmetal heating tube.
