Abstract
The utility model discloses an electric water heater. The electric water heater comprises an inner container, a water inlet tube, a water outlet tube and a magnesium rod, wherein a water inlet is arranged on the inner container. The main technical characteristics of the electric water heater are that a water outlet is arranged on the inner container; the water outlet tube gets through the water outlet and extends to the inner container; the water outlet tube and the inner container are connected in a detachable sealing manner; and the magnesium rod is a hollow magnesium tube sleeved on the water outlet tube. The electric water heater has the characteristics that a step of sealing, matching and machining one water tube with the inner container interface of the electric water heater can be eliminated and water leakage probability of the electric water heater can be effectively reduced.
Description
Technical field
The utility model relates to a kind of electric heater.
Background technology
In the prior art, be typically provided with the cold water inlet of access cold water pipe, the hot water outlet that the heat supply water pipe accesses, the sewage draining exit that the magnesium rod is installed on the inner container of electric water heater, three holes that namely are commonly called as are referring to shown in Figure 1.Owing in the manufacture process processing technology that is sealed and matched between cold water pipe and water inlet, hot-water line and delivery port, magnesium rod and the sewage draining exit is difficult to reach the requirement of zero-fault, many interfaces are with regard to the manufacturing procedure that is sealed and matched between many one water pipes and inner container interface on the electric heater, cause the electric heater probability of leaking to increase.For overcoming defects, electric heater is developed.
Summary of the invention
Technical problem to be solved in the utility model is the electric heater that will provide a kind of, effectively reduces the electric heater probability of leaking.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of electric heater, comprise inner bag, water inlet pipe, outlet pipe, magnesium rod, be provided with water inlet on the inner bag, also be provided with discharge outlet on the inner bag, described outlet pipe passes discharge outlet and stretches into inner bag, removable seal is connected between outlet pipe and the inner bag, and described magnesium rod is for being sleeved on the hollow magnesium pipe on the outlet pipe.
It comprises that also sealing is fixedly mounted on the titting water outlet on the discharge outlet, and outlet pipe is connected with the inner bag removable seal by titting water outlet.
Described magnesium rod is provided with magnesium rod inner nut, and outlet pipe is provided with the first external screw thread, and the magnesium rod is threaded with the first external screw thread on the outlet pipe by magnesium rod inner nut.
Described magnesium rod stretches into titting water outlet, is provided with seal washer between magnesium rod and the titting water outlet.
Described titting water outlet is provided with internal thread, and outlet pipe is provided with the second external screw thread, and outlet pipe is threaded with the internal thread of water pipe head by the second external screw thread.
The end that described magnesium rod stretches into titting water outlet is provided with boss, seal washer is sleeved on the boss, titting water outlet is provided with the first positioning table, is provided with the second positioning table between the first external screw thread of outlet pipe and the second external screw thread, and seal washer is also between the first positioning table and the second positioning table.
Also be provided with copper washer on the described seal washer.
Described seal washer is silicone gasket.
Described outlet pipe is the glass fiber material manufacturing.
The utility model is compared the beneficial effect that produces with background technology:
1, because the utility model adopts at inner bag water inlet and the sewage draining exit on the inner bag in the discharge outlet replacement prior art is set, outlet pipe passes described discharge outlet and stretches into inner bag, removable seal is connected between outlet pipe and the inner bag, hollow magnesium rod is sleeved on the outlet pipe, by reducing the procedure of processing that is sealed and matched of a water pipe and interface, therefore can effectively reduce the probability of leaking of electric heater.
Description of drawings: Fig. 1 is the structural representation of electric heater in the prior art;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the amplification view at A place among Fig. 2;
Fig. 4 is the explosive view of outlet pipe 5 in the utility model, water pipe head 7, magnesium rod 6, seal washer 8, copper washer 9.
The specific embodiment: shown in accompanying drawing 2, accompanying drawing 3, accompanying drawing 4, the electric heater in the present embodiment comprises inner bag 1, water inlet pipe 10, and outlet pipe 5, magnesium rod 6, inner bag 1 are provided with water inlet 2 and discharge outlet 4.
Be welded with titting water outlet 7 on the discharge outlet 4, titting water outlet 7 connects as one with inner bag 1 by welding, and outlet pipe 5 passes titting water outlet 7 and stretches in the inner bag 1, and namely outlet pipe 5 is connected by removable seal between titting water outlet 7 and the inner bag 1.
Be provided with internal thread 71 and the first positioning table 72 on the titting water outlet 7.
The body of outlet pipe 5 in inner bag 1 is set with magnesium rod 6, to prevent the inner bag corrosion and to stop incrustation scale to generate.End near discharge outlet 4 on the magnesium rod 6 is provided with magnesium pipe inner nut 62, and magnesium rod 6 is stretched into titting water outlet 7, and the overall diameter of magnesium rod 6 is a bit larger tham the interior diameter of titting water outlet 7, makes between magnesium rod 6 and the titting water outlet 7 to closely cooperate.An end that stretches into titting water outlet 7 on the magnesium rod 6 also is provided with boss 61, successively is inserted in copper washer 9 and silicone gasket 8 on boss 61.
