Abstract
The utility model provides an electric water heater, which comprises a shell, two water tanks, an electric heating element, a temperature control device, an inlet pipe, an outlet pipe and other parts. It features that the electric heating element is not immersed in water tank but placed between two water tanks to form indirect heating mode. Compared with the existing electric water heater, the electric water heater is safe and reliable, has long service life, low manufacturing cost and very convenient use.
Description
The utility model relates to a kind of electric heater that utilizes electrical heating water.
The structure of the electric heater that use in existing family or hotel is made of parts such as shell, metal water tank, electrothermal tube, temperature controller and import and export water pipes, its mode of heating is a directly-heated type, be that electrothermal tube directly immerses in the water tank, electrothermal tube is immersed under the water level, the structure of its electrothermal tube is that metal sleeve entangles earthenware, and heating wire is through at the earthenware center.Use this direct-heating type electric heater to exist following shortcoming: 1. blow heating wire easily, particularly unmanned guard or careless manipulation very easily during anhydrous or not submergence of water electrothermal tube in the water tank make that electrothermal tube is overheated to be burnt out.2. poor stability, if metal sleeve service time long corroded or the human factor damage after will leak, water directly contacts with heating wire, will get an electric shock during people's shower and cause life danger.Manufacturing firm is in order to guarantee the high safety of electric heater, the material and the parts of the water temperature of the reliable design of having to, water level control system and use costliness, and such electric heater cost is too high, and the user is difficult for accepting.3. accumulation of heat is poor.The direct-type electric heater closes electricity or the back electrothermal tube that has a power failure no longer heats, and water tank promptly dispels the heat to shell by heat-insulation layer, and water temperature descends fast.
The purpose of this utility model provides the electric heater that a kind of safe and reliable, life-span is long, the accumulation of heat time is long, cost is low.
Primary structure of the present utility model comprises the parts such as bypass valve of shell, water tank, heating, temperature control system, import and export water pipe, water transfer temperature, with the difference of existing electric heater structure is to adopt the indirect-heating heating, be heating directly bubble go in the water tank, but the sidewall that is placed on water tank is by the water in the metallic plate indirect water tank.For heat energy is made full use of, set up two water tanks in the water heater, heating is clipped between two water tanks; The structure of heating is ceramic wafer or the ceramic rod that the center is wound with heating wire, overlap with earthenware again or pack tightly with ceramic wafer all around, middle space is filled with high-temperature insulation and is easy to material such as ceramic powder, the glass dust etc. of heat conduction, make heating wire be difficult for becoming flexible and exposing, outermost layer compresses with metal tube or the metallic plate cover that materials such as aluminium, copper or stainless steel are made again.Heating is generally short slightly than the water tank of both sides, two or two other side are with asbestos board or filled thermal insulation materials, to reduce heat loss, the design class of the electric control system of water heater, the bypass valve of importing and exporting water pipe and water transfer temperature and existing water heater is seemingly determined during manufacturing as required.
Below in conjunction with accompanying drawing enforcement structure of the present utility model is described:
Fig. 1 is the structural representation of the utility model indirect-heating electric heater;
Fig. 2 is the structural representation of heating.
From Fig. 1, see, two water tanks 3 and 5 are housed in the housing 1 of this electric heater, in the middle of two water tanks is indirect-heating heating 6, two of heating 6 and two other sidewall have insulation material layer 8, inlet tube 7 and outlet 10 are contained in the below of housing 1 respectively, there is the bypass valve 9 of regulating water temperature the centre, after entering from inlet tube 7, cold water can feed two water tank heating by water pipe 4 earlier, also can lead to outlet 10 from bypass valve 9, water leads to outlet 10 in water tank heating back from water pipe 2, in order to make the resistance to compression of water tank energy, the sidewall of two water tanks can add resistance to compression steel plate or reinforcement.
The inner core of the heating 6 of Fig. 2 is porcelain rod or porcelain plate 15, is wound with heating wire 14 above, overlaps with ceramic wafer or earthenware 12 again, the intermediate layer is a packing layer 13, its useful ceramics powder, the Heat Conduction Material of glass dust or other heatproof, insulation, outermost layer are metallic plate or metal tube 11.
Circuits System mainly is equipped with power switch, indicator lamp, temperature control equipment or power retaining in casing, concrete structure can design as required.
Characteristics of the present utility model are:
1. water heater adopts indirect-heating, and heating is not placed in the water tank and contacts with water, and the safe coefficient height is not even the bad or radiator leak of heating sealing still can leak electricity.
2. heating is by the conduction of metallic plate heat, and heated filament is difficult for overheated rubescent, thereby the life-span is long.
3. the water tank accumulation of heat is the heating heating by being clipped in the middle, so heat storage performance is good, temperature retention time is long.
4. the electric heater volume is little, and the area that takes up space is little.
5. material requirements is not high, and cost is low, and particularly heating can reduce about half than common electrical heat pipe cost.
Claims (2)
1, a kind of electric heater, comprise housing (1), water tank, power switch, temperature control equipment, import and export pipe and water temperature adjusting bypass valve (9), it is characterized in that being equipped with in this electric heater two water tanks (3) and (5), indirect-heating heating (6) is arranged between the water tank, and two of heating and two other sidewall are equipped with heat-barrier material.
2, according to claims 1 described electric heater, the inner core that it is characterized in that the indirect-heating heating is porcelain rod or porcelain plate (15), be wound with heating wire (14) above, overlap again with ceramic wafer or earthenware (12), the intermediate layer is heat conductive insulating filler (13), and outermost layer is metallic plate or metal tube (11).
