Abstract
The utility model relates to an electric water heater which comprises an inner container (1), a flange (2), an electric heating pipe (3) and a sacrificial anode magnesium bar (4), wherein the flange (2) is hermetically arranged at the bottom of the inner container (1), and the electric heating pipe (3) is hermetically arranged on the flange (2). The electric water heater is characterized in that a blowdown pipe (5) is further arranged on the flange (2), the sacrificial anode magnesium bar (4) is detachably and hermetically arranged in the blowdown pipe (5), and one end of the sacrificial anode magnesium bar (4) is extended from the blowdown pipe (5) into the inner container (1). An outer thread (50) is arranged at the outer end of the blowdown pipe (5) and provided with a sealing nut (6) that is connected with the outer thread (50) in a matching manner, and an inner threaded hole (60) is arranged at the inner end of the sealing nut (6); and a screw rod (7) is arranged at the rear end of the sacrificial anode magnesium bar (4) and screwed on the inner threaded hole (60) of the sealing nut (6). The electric water heater adopting the structure is convenient to blow down and replace the sacrificial anode magnesium bar.
Description
Technical field
The utility model relates to a kind of architecture advances of electric heater.
Technical background
Continuous development along with the closed electrical water heater industry, the closed electrical water heater product is constantly weeded out the old and bring forth the new, and is also more and more higher to the requirement of electric heater, requires not only that electric heater capacity is big, volume is little, and require the shape of electric heater changeable, can adapt to the demand of special closed electrical water heater.Some closed electrical water heater small product size are done littler and littler, and electric heater not only comprises the electric heating function element, and also need possess the necessary structure of closed electrical water heater product, as dirt eliminating function and anti-erosion function.The water inlet pipe of conventional electric heating device, outlet pipe and sacrificial anode magnesium rod be more to be installed on the sidewall of inner bag, the electric heater of this structure, be difficult to be emptied completely the sewage in the inner bag, and sacrificial anode magnesium rod generally also is fixed installation, changes very inconvenient.
The utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of electric heater that makes things convenient for blowdown and change sacrificial anode magnesium rod is provided.
The technical solution of the utility model is: a kind of electric heater, comprise inner bag (1), flange (2), electrothermal tube (3) and sacrificial anode magnesium rod (4), flange (2) sealing is installed in the bottom of inner bag (1), electrothermal tube (3) sealing is installed on the flange (2), it is characterized in that: also be provided with blow-off pipe (5) on the described flange (2), sacrificial anode magnesium rod (4) removably seals and is installed in the blow-off pipe (5), and an end extends in the inner bag (1) from blow-off pipe (5).
The outer end of described blow-off pipe (5) offers external screw thread (50), and external screw thread (50) is provided with the sealing nut (6) that is mated connection, and the inner end of sealing nut (6) offers internal thread hole (60); The rear end of described sacrificial anode magnesium rod (4) is provided with screw rod (7), and screw rod (7) is tightened on the internal thread hole (60) of sealing nut (6).
Described blow-off pipe (5) is welded on the flange (2).
Described inner bag (1) has more than two, and the bottom of each inner bag 1 and top interconnect by communicating pipe (8) respectively.
Described electrothermal tube (5) is the electrothermal tube of stainless steel casing, is welded on the flange (2).
Good effect of the present utility model: on the flange that is positioned at the inner bag bottom, blow-off pipe is set, can be easily with the sewage emptying in the inner bag.Sacrificial anode magnesium rod removably seals and is installed in the blow-off pipe, and an end extends to from blow-off pipe in the inner bag, this structural design, when needing to change sacrificial anode magnesium rod, only need take out from blow-off pipe, the sacrificial anode magnesium rod that more renews then is all right, very convenient.

Fig. 2 is the flange section stereogram;
Fig. 3 is the flange section sectional view;
Fig. 4 is flange section STRUCTURE DECOMPOSITION figure.
The specific embodiment
Be described in further detail below in conjunction with the specific embodiment of accompanying drawing electric heater.
As Fig. 1-shown in Figure 4, electric heater of the present utility model mainly is made up of inner bag 1, flange 2, electrothermal tube 3, sacrificial anode magnesium rod 4 and water inlet pipe, outlet pipe (not providing among the figure), flange 2 sealings are installed in the bottom of inner bag 1, electrothermal tube 3 sealings are installed on the flange 2, welding for convenience, electrothermal tube 5 adopts the electrothermal tube of stainless steel casing, is welded on the flange 2.In addition, the sewage in the emptying inner bag 1 also is welded with blow-off pipe 5 on flange 2 for convenience, and sacrificial anode magnesium rod 4 removably seals and is installed in the blow-off pipe 5, and an end extends in the inner bag 1 from blow-off pipe 5.Mounting structure can adopt Fig. 3, structure shown in Figure 4, promptly offer external screw thread 50 in the outer end of blow-off pipe 5, external screw thread 50 is provided with the sealing nut 6 that is mated connection, the inner end of sealing nut 6 offers internal thread hole 60, the rear end of sacrificial anode magnesium rod 4 is provided with screw rod 7, and screw rod 7 is tightened on the internal thread hole 60 of sealing nut 6.In order to increase the volume of electric heater, inner bag 1 can adopt more than two, and the bottom of each inner bag 1 and top interconnect by communicating pipe 8 respectively, has adopted two inner bags 1 in the present embodiment.
Sacrificial anode magnesium rod 4 reduces the erosion on metal inner tube 1 and electrothermal tube 3 surfaces by the Electronic Protection metal inner tube 1 in the release magnesium rod and the surface of electrothermal tube 3.During energising work, electrothermal tube 3 heating work are also heated the water of closed electrical water heater inner bag.During blowdown, the sealing nut on the blow-off pipe 56 unclamped and take out, make the incrustation scale in the inner bag 1 be discharged to the inner bag outside, reach the effect of draining, blowdown with water with the flange 2 of sacrificial anode magnesium rod 4 from electric heater.Electric heater of the present utility model has stable working state, reliability height, simplifies product structure design, improved production technology, distinguishing feature such as reduce production costs, and has satisfied the actual demand of electric heater.
