Abstract
The utility model relates to an electric water heater, comprising a heating bin with heating wires and is characterized in that the external wall of the outermost layer of the heating bin is provided with a water cooling jacket, a water inlet of the water cooling jacket is connected with an external water supply pipe while an exit thereof is communicated with a water inlet of the external heating bin. Compared with the prior art, the utility model has the advantages of preventing energy of hot water from dissipating through the external wall of the heating bin, high heating efficiency and rapid temperature rising.
Description
Technical field:
The utility model relates to a kind of water heater.
Background technology:
Existing electric heater is no matter be individual layer or double-deck heating cabinet, the bulkhead of its outermost heating cabinet is directly with extraneous contacted, like this, the hot water energy in the heating cabinet will scatter and disappear in large quantities by the very big storehouse outer wall of area, has greatly influenced the thermal efficiency of electric heater.
Summary of the invention:
Goal of the invention of the present utility model is to provide a kind of hot water energy that can prevent to scatter and disappear by the heating cabinet outer wall, and the thermal efficiency is high, the electric heater of quick heating.
The utility model is to realize like this, comprise the heating cabinet that is placed with heating wire, its special feature is to be provided with a cooling jacket at the outer wall of outermost layer heating cabinet, and the water inlet of cooling jacket links to each other with extraneous feed pipe, and the cooling jacket outlet communicates with the water inlet of outer heating cabinet.During work, the cold water chuck of flowing through earlier just enters heating cabinet, and like this, the heat that the heating cabinet outer wall comes out is just absorbed by flowing cold water in the cooling jacket, cold water obtains preliminary preheating and just enters and carry out Fast Heating in the heating cabinet and heat up and become hot water, with supply user's instructions for use.
The utility model compared with the prior art owing to adopted cooling jacket, the heat energy that utilizes the heating cabinet outer wall to scatter and disappear carries out preheating to cold water, therefore, has and can prevent that the hot water energy scatters and disappears by the heating cabinet outer wall, the thermal efficiency is high, the advantage of quick heating.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Now in conjunction with the accompanying drawings and embodiments the utility model is done and is described in further detail:
As shown in the figure, the utility model mainly is that the outer wall 1 at heating cabinet is provided with a cooling jacket 2 and forms, heating cabinet is inside and outside double-deck heating cabinet 3,4, every layer of heating cabinet is equipped with heating wire 5, the bottom inlet 6 of internal layer heating cabinet 3 communicates with the outlet at bottom 7 of outer heating cabinet 4, the top of the outlet pipe 8 through internal layer heating cabinets 3 of internal layer heating cabinet 3, the delivery port 9 of cooling jacket 2 upper ends communicates with the upper end water inlet 10 of outer heating cabinet 4, and the lower end water inlet 11 of cooling jacket 2 links to each other with water inlet pipe 12.
