Description
Technical field
The utility model relates to field of water heaters, is specifically related to a kind of electric water heater.
Background technology
At present, electric heater has become the household electrical appliance generally used in family.Based on safety, the considering of energy-saving and environmental protection angle, anode stub (being generally magnesium rod) is all equipped with in the inner bag of electric heater, for reducing corrosive ions in water body to the infringement of inner bag metal level, delay speed that inner bag metal level is corroded and intensity thus; But anode stub (magnesium rod) limited efficiency, usual one, in two years anode stub (magnesium rod) will disappear by natural volume, need periodic replacement but inevitably can produce incrustation scale in inner bag simultaneously.Therefore, except being provided with into except water interface and water outlet mouthpiece on the inner bag of current electric heater, be also provided with the sewage draining exit for discharging incrustation scale so that cleaning time sewage discharge.
Need during the blowdown of traditional electrical water heater by special tool(s), nut plug to be screwed off, in blowdown process, magnesium rod is also removed, and whole blowdown process is complicated, needs professional to adopt specific purpose tool to operate, moreover, because during blowdown, sewage flashes, and need to wait water temperature in water heater to be reduced to and just can operate without when scald hidden danger human body, the whole blowdown process took time is long, employ manual tools many, easily make dirty clothing and surrounding environment.
Utility model content
The purpose of this utility model is complicated according to current electric heater blowdown process, the blowdown process took time is grown, it is many to employ manual tools, the deficiency of clothes and the surrounding environment of easily making dirty, proposes that a kind of blowdown process restraining factors simple to operate, whole are few, a kind of electric water heater of can not make dirty clothing and surrounding environment.
The utility model adopts following technical scheme:
A kind of electric water heater, comprise heating tube and inner bag, described inner container outer cover has heat-insulation layer and shell, drainpipe is provided with bottom inner bag, outlet pipe and water inlet pipe, it is characterized in that, described drainpipe is connected with plug-in blowdown assembly, described plug-in blowdown assembly comprised jacket pipe, described the outer of jacket pipe of crossing is arranged with plastic bushing, described mistake between jacket pipe outer wall and plastic bushing inwall is provided with draining tube wall, described cross bottom jacket pipe with plastic bushing bottom compact siro spinning technology, described jacket pipe is excessively the tubular structure of top seal, described mistake on the upside of jacket pipe outer wall is provided with the second annular seal ring, in described jacket pipe outer wall excessively, side is provided with clamping pawl, described mistake on the downside of jacket pipe outer wall is provided with water hole, the first annular seal ring is provided with on the upside of the inwall of described plastic bushing, the bottom of described plastic bushing is provided with discharge outlet, described draining tube wall side is provided with the 3rd annular seal ring.
Preferably, described jacket pipe top of crossing is provided with threaded post.
Preferably, the position of described 3rd annular seal ring is higher than the position of the first annular seal ring.
Preferably, the same level position of described draining tube wall inwall and clamping pawl is provided with buckling groove.
Preferably, the height of described first annular seal ring is higher than the height of the second annular seal ring.
The beneficial effect that the utility model has is: this electric water heater structure is simple, easy for installation, average family member without the need to by means of instrument, by plug-in blowdown modular construction, free-hand can will cross jacket pipe screw out, blowdown is carried out to electric heater, or change magnesium rod, in blowdown process, sewage only can be flowed out by discharge outlet, household drain system can be caused by aqueduct, any pollution can not be caused to the clothing of operating personnel and surrounding environment.Plug-in blowdown modular construction removes and installs one and is screwed into position, simple to operation, and whole blowdown process restraining factors are few.
Accompanying drawing explanation
Fig. 1 is a kind of electric water heater structural representation.
Wherein, 1 is discharge outlet, and 2 is magnesium rod, and 3 is draining tube wall, and 4 is the first annular seal ring, 5 is the second annular seal ring, and 6 is buckling groove, and 7 is clamping pawl, and 8 is threaded post, and 9 was jacket pipe, 10 is water hole, and 11 is plastic bushing, and 12 is the 3rd annular seal ring, and 13 is inner bag.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, detailed description of the invention of the present utility model is described further:
As shown in Figure 1, a kind of electric water heater, comprise heating tube and inner bag 13, described inner bag 13 is covered with heat-insulation layer and shell, drainpipe is provided with bottom inner bag 13, outlet pipe and water inlet pipe, it is characterized in that, described drainpipe is connected with plug-in blowdown assembly, described plug-in blowdown assembly comprised jacket pipe 9, described the outer of jacket pipe 9 of crossing is arranged with plastic bushing 11, described mistake between jacket pipe 9 outer wall and plastic bushing 11 inwall is provided with draining tube wall 3, described cross bottom jacket pipe 9 with plastic bushing 11 bottom compact siro spinning technology, described jacket pipe 9 is excessively the tubular structure of top seal, described mistake on the upside of jacket pipe 9 outer wall is provided with the second annular seal ring 5, in described jacket pipe 9 outer wall excessively, side is provided with clamping pawl 7, described mistake on the downside of jacket pipe 9 outer wall is provided with water hole 10, the first annular seal ring 4 is provided with on the upside of the inwall of described plastic bushing 11, the bottom of described plastic bushing 11 is provided with discharge outlet 1, described draining tube wall 3 side is provided with the 3rd annular seal ring 12.
