Abstract
The utility model discloses an electric water heater, comprising a casing 1, an inner bag 2, a tubular electric heating element 4, an admitting pipe 5 and a rising pipe 6, wherein, the inner bag 2 is arranged in the casing 1, the tubular electric heating element 4 is sealed in the inner bag 2 by the sealed cap 7, the admitting pipe 5 and the rising pipe 6 are inserted into the inner bag 2, which is characterized in that , the inner bag 2 is a plastic monolayer inner bag, a foam thermal insulator 3 is filled between the inner bag 2 and the casing 1, using the monolayer plastic inner bag 2 , greatly reduces the cost, in favor of spreading and using; and the foam thermal insulator 3 makes the heat preservation effect of the monolayer plastic inner bag 2 is most consistent with the heat preservation effect of the two layer stainless steel inner bag.
Description
Technical field
The utility model relates to a kind of electric heater.
Background technology
At present, various electric heaters emerge in an endless stream, and the life that it has made things convenient for people becomes requisite household electrical appliance in people's life.But in the structure of existing electric heater, its inner bag is generally the stainless steel double-decker, though high insulating effect, the cost height has influenced promoting the use of of electric heater.
The utility model content
The purpose of this utility model provides a kind of electric heater of low cost of manufacture.
The utility model includes shell body, inner bag, electrothermal tube, water inlet pipe, outlet pipe, wherein, inner bag places in the shell body, electrothermal tube is sealed in the inner bag with seal cover, inlet tube and outlet tube is inserted in the inner bag, it is characterized in that inner bag is a plastics individual layer inner bag, the space between inner bag and the shell body is filled with the foam thermal insulation body; Because inner bag is a monolayer plastic, greatly reduces manufacturing cost, in addition, is filled with the foam thermal insulation body between inner bag and the shell body, guaranteed its heat insulation effect, and the foam thermal insulation body is cheap, can not increase whole cost.
Description of drawings
Fig. 1 is the axial cutaway view of the utility model embodiment.
Fig. 2 is that A-A among Fig. 1 is to cutaway view.
The specific embodiment
See also Fig. 1, shown in Figure 2, the utility model includes shell body 1, inner bag 2, electrothermal tube 4, water inlet pipe 5, outlet pipe 6, wherein, inner bag 2 places in the shell body 1, electrothermal tube 4 is sealed in the inner bag 2 with seal cover 7, and inlet tube and outlet tube 5,6 is inserted in the inner bag 2, it is characterized in that, inner bag 2 is a plastics individual layer inner bag, and the space between inner bag 2 and the shell body 1 is filled with foam thermal insulation body 8; The use of monolayer plastic inner bag 2 greatly reduces cost, helps promoting the use of; Filled and process thermal insulator 8 makes the heat insulation effect of the heat insulation effect of monolayer plastic inner bag 2 and double-layer stainless steel inner bag basic identical.
