Abstract
The utility model relates to an electric water heater, particularly the electric water heater which uses forced water flow to form direction flow, comprising an electric heating pipe, a cylinder body, a mounting plate, a cover cap, a blank pipe, and a swirling flow diaphragm plate. The blank pipe is arranged at the center in the cylinder body, and one end is fixed on the mounting plate. When entering from a water inlet of the cylinder body, the water flow forms annular swirling flow through the guiding of the blank pipe and the swirling flow diaphragm plate, and the total cross-section washing of the electric heating pipe is improved; accordingly, the service life and the heat transfer effect are improved; simultaneously, the phenomenon that the power consumption of a water pump is increased because of an oversize flow area is avoided.
Description
The utility model relates to a kind of electrical heating water heater, particularly adopts the electrical heating water heater of forcing current to make directed flow.
The conventional electric heating water heater generally all has a cylindrical shell that has inlet opening and apopore, and some electric heating tubes are housed in cylindrical shell, and cold water enters in the cylindrical shell from the inlet opening, through electric heater for heating, discharges from apopore.Current in cylindrical shell are done vertically to flow along electric heating tube, its deficiency is that the flow velocity in the flow area of water is inhomogeneous, and the electric heating tube cooling at flow velocity place on the low side is relatively poor, the surface thermal load height, easily produce vaporization phenomenon, not only reduce the service life of electric heating tube but also influence heat-transfer effect.Adopt for solving above-mentioned deficiency, also having in design, in the runner of current, place lateral partitions, in runner, do stirring up and down, accelerate the flow velocity of water, improve the anti-devaporation of heat-transfer effect by lateral partitions to force current.But also unavoidably there is the vortex in this structure, causes the local scour of electric heating tube not exclusively, simultaneously owing to be provided with lateral partitions, has increased flow resistance, has strengthened the power consumption of the water pump that is connected the place, inlet opening.
The purpose of this utility model provides a kind of electrical heating water heater, and it can make current make the ring-type eddy flow, strengthens the washing away of the total cross-section of electric heating tube prevented partial vaporization, to improve heat-transfer effect, increases the life-span of electric heating tube.Simultaneously, do not increase the power consumption of water pump.
For achieving the above object, the utility model comprises electric heating tube, cylindrical shell, installing plate, cover cap, electric heating tube is positioned at cylindrical shell, the one end is fixed on the installing plate, installing plate is positioned at an end of cylindrical shell, one end of its surrounding and cylindrical shell is tightly connected, cover cap covers installing plate, two ends at cylindrical shell respectively have an inlet opening and osculum, and connecting flange respectively is housed on the aperture, it is characterized in that: also comprise blind pipe and eddy flow diaphragm plate, blind pipe is positioned at the cylindrical shell center, the one end is fixed on the installing plate, at the two ends of blind pipe one eddy flow diaphragm plate is housed respectively, and electrothermal tube passes the eddy flow diaphragm plate and is distributed in the form of a ring between cylindrical shell and the blind pipe.When the water that enters from the inlet opening in the cylindrical shell, through the guiding of eddy flow diaphragm plate and blind pipe, form the ring-type eddy flow, the total cross-section of electric heating tube is washed away.
Above-mentioned eddy flow diaphragm plate, the center has a hole, so that be sleeved on the blind pipe, around this aperture, be connected with the fanning strip that equates with electric heating tube quantity, have a hole in the every fanning strip, the aperture is slightly larger than the diameter of electric heating tube, so that electric heating tube passes, it is one identical with water (flow) direction that the fan-shaped folding of half block in every fanning strip has, and be less than or equal to 30 ° angle, make to form a water stream channel between adjacent two fanning strips, force current to make the ring-type eddy flow, to form washing away the electric heating tube total cross-section.
Above-mentioned cylindrical shell and cover cap all have inside and outside layer to constitute, and are placed with heat-insulating material between the inside and outside layer.
The utility model is owing to adopted the structure of eddy flow diaphragm plate and blind pipe, make the current in the cylindrical shell make the ring-type eddy flow, the total cross-section that had both strengthened electric heating tube washes away, and electric heating tube is in forces radiating state preferably, has improved the life-span and the heat-transfer effect of electric heating tube; Can avoid increasing the power consumption of place, inlet opening water pump again because of flow area is excessive.
Provide embodiment of the present utility model and accompanying drawing below, also further specify in conjunction with the accompanying drawings:
Fig. 1 is a positive view of the present utility model;
Fig. 2 is the front view of eddy flow diaphragm plate in the utility model;
Fig. 3 is the vertical view of fanning strip in the utility model;
By shown in Figure 1, cylindrical shell (1) and cover cap (5) constitute by inside and outside layer, between inside and outside layer heat-insulating material are housed, and heat-insulating material can be mineral wool, rock wool or EVP foaming polyamine fat etc. according to the difference of use occasion.Electric heating tube (3) is positioned at cylindrical shell (1), and the one end is fixed on the installing plate (4).The surrounding of installing plate (4) is connected with an end face seal of cylindrical shell (1).Cover cap (5) covers installing plate (4).Respectively have an inlet opening (6) and osculum (7) at the two ends of cylindrical shell (1), and connecting flange (8), (9) are housed respectively.Blind pipe (10) is positioned at cylindrical shell (1) center, and the one end is fixed on the installing plate (4).Respectively be with an eddy flow diaphragm plate (11), (12) at the two ends of blind pipe (10), electric heating tube (3) passes eddy flow diaphragm plate (11), (12) are distributed between cylindrical shell (1) and the blind pipe (10).
By shown in Figure 2, the center of eddy flow diaphragm plate has hole (13), be connected with six block-shaped identical fanning strips (14) all around, have a hole (15) in the every fanning strip (14), the aperture is slightly larger than the electric heating tube diameter, formation had both made things convenient for electric heating tube to pass, and a spot of direct current current washing away electric heating tube and (15) intersection, hole arranged again.Half block in the every fanning strip (14) is fan-shaped along the water (flow) direction angle of turning back, and makes to form a water stream channel between adjacent two fanning strips, forces current to make the ring-type eddy flow.
By shown in Figure 3, fan-shaped the turning back along water (flow) direction of the half block in every fanning strip one is less than or equal to 30 ° angle.
