Abstract
The utility model relates to an electric water heater inlet pipe including a stopper and an inlet pipe body, wherein the inlet pipe body includes an inner pipe and an outer pipe, the outer pipe is arranged outside the inner pipe, the stopper is arranged at the top end of the inner piper and the outer pipe in a sealing manner, a gap is left between the inner pipe and the outer pipe, the upper end of the inner pipe is provided with a transitional hole, and the inlet pipe is characterized in that the bottom of the outer pipe is provided with a diversion hole which is communicated with the gap. The inlet pipe provided is advantageous in that main stream directly flows downwards via the diversion hole in the bottom of the outer pipe to enable a water outlet to be far away from a hot water layer and a heater, thus, the cold water flowed therein has less disturbance on the hot water at the upper layer of the inner side of an inner container. Therefore, the inlet pipe provided increases the output quantity of the hot water and effectively improves the hot water output rate of a water heater.
Description
Technical field
The utility model relates to a kind of water inlet pipe that improves structure, is specifically related to a kind of water inlet pipe of electric heater.
Background technology
The height of the hot water delivery rate of existing electric heater water intake mode main and current has very large relation, and then hot water delivery rate is just low soon for the water inlet water velocity, otherwise namely high.The water intake mode of water inlet tube of electric water heater in the market can be divided into following two classes basically:
The first kind is to be with anti-electric wall water inlet pipe structure, it is the mode of bimetallic tube normally, after from bottom to top flowing to top by internal pipeline when current enter, orifice flow by internal pipeline goes out, after the outflow again by the inner and outer pipes gap from top to bottom, finally from the lower end outer tube wall radially apopore flow out and to enter inner container of electric water heater;
What another kind of water inlet pipe adopted is single tube, adopts the mode of side perforate; Current directly from bottom to top enter from water inlet pipe, directly flow out by the hole of side to enter inner container of electric water heater.
More than this two class all be to slow down water velocity by the mode of many perforates, to improving hot water delivery rate certain effect is arranged, but limits because of structure, effect is also not obvious, causes the hot water delivery rate of product generally not high.
Summary of the invention
The purpose of this utility model is the shortcoming that overcomes above-mentioned prior art, and a kind of water inlet pipe that can significantly slow down the water velocity of water inlet pipe and improve the electric heater of hot water delivery rate is provided.
The technical scheme that realizes the utility model purpose is: a kind of water inlet pipe of electric heater, comprise plug and water inlet pipe, wherein said water inlet pipe comprises inner tube and outer tube, outer tube sleeve is located at outside the inner tube, the gap is left between described inner tube and the outer tube in the top that is installed in inner tube and outer tube of described plug sealing, is provided with transitional pore in the upper end of inner tube, it is characterized in that described outer tube bottom surface is provided with flow-guiding mouth, flow-guiding mouth is connected with the gap.
The lower end tube wall of described outer tube is provided with the multilayer apopore, and described apopore top-down aperture is greatly the tower distribution by little the change gradually.
Lower end at described outer tube is provided with spacer sleeve, is provided with locating ring at described spacer sleeve.
Described locating ring is ring-type, and the inner surface of locating ring is provided with columnar protrusions axial more than two, and the upper surface of described columnar protrusions exceeds the upper surface of locating ring.
The radially internal diameter of described columnar protrusions cooperates with the inner tube crest clearance, the internal diameter matched in clearance of the radial outer diameter of columnar protrusions and water inlet pipe outer tube, the lower axial end of columnar protrusions and spacer sleeve location.
The bottom surface of described outer tube is provided with spacer, and an end of described spacer peaks at the outer surface of inner tube.
The upper end of described spacer sleeve extends angle, and an end of described angle peaks at the inwall of outer tube.
The cross section of described apopore is circular, square or rectangular.
The utility model beneficial effect compared with prior art is: because the outer tube bottom surface is provided with the flow-guiding mouth that is connected with the gap, main current directly enter inner bag by the space between locating ring and inner tube and outer tube downwards, delivery port is farther from hot water layer and heater, thereby so that the cold water that flows to is minimum for the hot water disturbance on upper strata, inner bag inside, increased the output quantity of hot water, Effective Raise the hot water delivery rate of water heater.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Embodiment one
Shown in Fig. 1 to 5, a kind of water inlet pipe of electric heater, comprise plug 1 and water inlet pipe 2, wherein said water inlet pipe 2 comprises inner tube 21 and outer tube 22, and outer tube 22 is set in outside the inner tube 21, the top that is installed in inner tube 21 and outer tube 22 of described plug 1 sealing, leave gap 23 between described inner tube 21 and the outer tube 22, be provided with transitional pore 211 in the upper end of inner tube 21, the utility model characteristics are that described outer tube 22 bottom surfaces are provided with flow-guiding mouth 221, and flow-guiding mouth 221 is connected with gap 23.
The lower end tube wall of described outer tube 22 is provided with multilayer apopore 222, and described apopore 222 top-down apertures are greatly the tower distribution by little the change gradually.Be provided with in the present embodiment six layers of apopore 222, also can set out according to actual needs the number of plies in water hole 222, the cross section of apopore 222 is circular, and apopore 222 also can be square or rectangular;
In the present embodiment, be provided with spacer sleeve 3 in the lower end of described outer tube 22, be provided with locating ring 4 at described spacer sleeve 3.
Described locating ring 4 is ring-type, and the inner surface of locating ring 4 is provided with columnar protrusions axial more than two 41, and the upper surface of described columnar protrusions 41 exceeds the upper surface of locating ring 4.In the present embodiment, be provided with three axial columnar protrusions 41 at the inner surface of locating ring 4, the quantity of columnar protrusions 41 also can be set according to actual needs.The radially internal diameter of described columnar protrusions 41 cooperates with inner tube 21 crest clearances, the internal diameter matched in clearance of the radial outer diameter of columnar protrusions 41 and water inlet pipe outer tube 22, the lower axial end of columnar protrusions 41 and spacer sleeve 3 location, make like this winner's current directly downwards enter inner bag by the space of 22 of locating ring 4 and inner tube 21 and outer tubes, delivery port is farther from hot water layer and heater, thereby so that the cold water that flows to is minimum for the hot water disturbance on upper strata, inner bag inside, increased the output quantity of hot water, Effective Raise the hot water delivery rate of water heater.
