The specific embodiment: the arrow among Fig. 1 is represented water (flow) direction, and dotted line is represented the thrust scope of water.The water inlet end of each parts is meant position, parts water inlet place and the following position of delivery port among the present invention, and the water side is meant position, parts delivery port place and the above position of delivery port.
As depicted in figs. 1 and 2, this electric heater water feed apparatus comprises outer tube 1 and the interior pipe of being made by any material in plastics, metal, pottery, the composite material 2.The maximum radial dimension of outer tube 1 water side is less than or equal to the minimum diameter size of electric heater water inlet pipe, make the water side of outer tube 1 can pierce into the electric heater water inlet pipe and protrude into inner container of electric water heater, outer tube 1 water inlet end is provided with outer tube water inlet 11, the top closure of outer tube 1 water side, the sidewall circumference of outer tube 1 water side evenly is provided with outer tube delivery port 12, pipe 2 in being provided with in the outer tube 1.Water inlet tube mouth 21 in interior pipe 2 water inlet ends are provided with, pipe delivery port 22 in the top of interior pipe 2 water sides or sidewall are provided with.In pipe 2 be placed in the outer tube 1 along axis direction, and fastened to each other with outer tube 1.Be provided with water flowing gap 3 between interior pipe 2 outer walls and outer tube 1 inwall, water flowing gap 3 is communicated with outer tube delivery ports 12 and interior pipe delivery ports 22.Outer tube delivery port 12 can all be positioned at the below of pipe delivery port 22, as Fig. 4, Fig. 5, shown in Figure 6, also can major part be positioned at the below of managing delivery port 22, as shown in Figure 3.
As Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, outer tube 1 all interfixes in the mode of interference fit with outer tube 1 with electric heater water inlet pipe, interior pipe 2.The outer wall of outer tube 1 water inlet end is provided with the outer tube fin 13 of being close to electric heater water inlet pipe inwall, and the outer wall of interior pipe 2 water inlet ends is provided with the interior pipe fin 23 of being close to outer tube 1 inwall.Simultaneously, outer tube 1 water inlet end outer wall, interior pipe 2 water inlet end outer walls are respectively arranged with outer Pipe Flange 14, interior Pipe Flange 24, push up mutually with the mouth of pipe of electric heater water inlet pipe water inlet end outer Pipe Flange 14 upper surfaces, push up mutually with the outer tube water inlet 11 of outer tube 1 interior Pipe Flange 24 upper surfaces, and both move on the axis direction of electric heater water inlet pipe to prevent outer tube 1, interior pipe 2.Outer tube fin 13, interior pipe fin 23, outer Pipe Flange 14, interior Pipe Flange 24 are circular, to stop current, prevent that current manage 2 and enter inner bag in water inlet is walked around the time.
In Fig. 3, Fig. 4, embodiment shown in Figure 5, interior Pipe Flange 24 be the structure of global formation with interior pipe 2, the reduction die cost.Interior Pipe Flange 24 also can adopt the structure that independently is provided with interior pipe 2 splits, to reduce the part replacement cost, its embodiment is: be provided with T shape cover 4 between outer tube 1 and interior pipe 2, T shape cover 4 is provided with the center water channel, the water inlet end of interior pipe 2 packs into the center water channel, interior Pipe Flange 24 is the shoulder of T shape cover 4, as shown in Figure 6.
Among the present invention, outer tube delivery port 12 center lines and horizontal angular range can be 0 °～40 °.For making things convenient for outer tube 1 water outlet downwards better, prevent that current are obstructed when the outer tube water outlet, outer tube delivery port 12 is downward-sloping, so outer tube delivery port 12 center lines and horizontal preferred angular range are 5 °～30 ° (figure does not show).When outer tube delivery port 12 center lines and horizontal angle during less than 5 °, outer tube delivery port 12 is too mild, and current when outer tube delivery port 12 flows out, a chain of collision reflection can take place with the mouth wall of outer tube delivery port 12 from top to bottom, produce turbulent flow, influence the water outlet effect; When outer tube delivery port 12 center lines and horizontal angle during greater than 30 °, outer tube delivery port 12 is steep excessively, and current flow out downwards from outer tube delivery port 12 rapidly, can not fully scatter, and influence the thrust scope of cold water.
For guaranteeing the water-flowing amount of water feed apparatus in the unit interval, the internal diameter of interior pipe 2 is 5～15mm.Simultaneously, the inner headed face of pipe 2 was long-pending in the area of the horizontal cross-section in the gross area of the shaft section of each outer tube delivery port 12, water flowing gap 3 (ignoring the arc transition position on outer tube 1 top and the gap between the interior pipe 2) all was not less than, guarantee that exhalant canal is not less than intake tunnel, make water outlet more smooth, prevent that hydraulic pressure from gathering.
The operation principle of this electric heater water feed apparatus: pipe 2 in the current that enter inner bag are introduced into, turning back then flows in the water flowing gap 3 between outer tube 1 and the interior pipe 2, again from the outer tube delivery port 12 inflow inner bags of outer tube 1.Because current when turning back, flow downward, when current when outer tube delivery port 12 flows out, current are under tap water hydraulic, gravity and effect of inertia, the trend of the motion that keeps down flows into inner bag, as shown in Figure 2.Cold water is that central shaft enters inner bag to injection all around with the electric heater water inlet pipe, and the state of the motion that keeps down, on the one hand, cold water sprays the thrust scope that can enlarge cold water to all around, promoting more hot water up rises, on the other hand, cold water moves downward and can reduce impact and the disturbance of cold water to the hot and cold water generation of layering in the inner bag, prevents that cold water from directly rising to the hot water layer and causing hot water layer's water temperature to descend.
During installation, earlier interior pipe 2 is mounted in the outer tube 1, both are combined to form water feed apparatus, again water feed apparatus integral body directly are mounted to inner container of electric water heater by the electric heater water inlet pipe from the electric heater outside, and are easy for installation, help reducing production costs.
