Referring to fig. 1-4, a household electric water heater comprises a housing 1, a heating pipe 2 is fixedly installed on one side of an inner cavity of the housing 1, a vertical water outlet pipe 3 is fixedly installed on the other side of the inner cavity of the housing 1, a water control tank 4 is fixedly installed on the bottom of the housing 1, a water inlet 5 is opened in the middle of the bottom of the water control tank 4, a water outlet 6 is opened on one side of the bottom of the water control tank 4 close to the water outlet pipe 3, a sewage outlet 7 is opened on the other side of the bottom of the water control tank 4, a first water inlet hole 401 is opened on one side of the top of the water inlet 5 inside the water control tank 4, a second water inlet hole 402 is opened on the other side of the top of the water inlet 5 inside the water control tank 4, the first water inlet hole 401 and the second water inlet hole 402 are both communicated with the water inlet 5, thereby ensuring that cold water can enter into an inner container of the water heater from both water inlet holes, a rotary spray head 8 is movably installed on the second water inlet hole 402 inside the inner cavity of the housing 1, the rotary spray head 8 can rotate and spray under the action of water pressure, scale in the inner container of the water heater is effectively washed and finally discharged from a sewage discharge hole 404, a communicated water outlet hole 403 is formed between the water outlet pipe 3 and the water outlet 6 in the water control box 4, the sewage discharge hole 404 communicated with the sewage discharge outlet 7 and the inner container is formed in the water control box 4, a transmission shaft 10 penetrating through a first water inlet hole 401 and the water outlet hole 403 is movably installed in the water control box 4, an impeller 9 is fixedly sleeved on the outer ring of the section, located on the water outlet hole 403, of the transmission shaft 10, the turntable 11 is fixedly sleeved on the outer ring of the section, located on the first water inlet hole 401, of the transmission shaft 10, the impeller 9 is driven to rotate along with the water outlet hole 403 when water is discharged, the transmission shaft 10 is used for transmitting the rotation of the impeller 9 to the turntable 11 so as to drive the impeller to rotate together, chutes 1101 are uniformly formed in the outer ring of the turntable 11, and a top block 12 is movably sleeved inside the chutes 1101, fixedly connected with pressure spring 13 between kicking block 12 and the spout 1101 diapire, water storage chamber 405 with first inlet opening 401 intercommunication is seted up to inside being located of water accuse case 4 between first inlet opening 401 and the apopore 403, water accuse case 4 is located the both sides of water storage chamber 405 and sets up rather than the air vent 406 of intercommunication, the top swing joint of air vent 406 has bellows 14, bellows 14's bottom fixedly connected with piston 15, water accuse case 4 is inside to be located and has seted up between second inlet opening 402 and the blowoff hole 404 and adjust air cavity 407, the equal movable sleeve joint in both ends of adjusting air cavity 407 has dog rack 16, the middle part movable mounting of adjusting air cavity 407 inner chamber has the gear 17 with dog rack 16 meshing, dog rack 16 outer end is the inclined plane, can conveniently push it inwards and drive the dog rack 16 of opposite side inwards to move simultaneously when receiving the pressure that acts on the inclined plane.

The water inlet cross-sectional area of the first water inlet hole 401 is larger than that of the second water inlet hole 402, the water inlet cross-sectional area of the first water inlet hole 401 is larger to ensure that incoming water is more moderate and cannot generate large impact and fluctuation, the first water inlet hole 401 is used for supplementing hot water used in the water heater, the second water inlet hole 402 is used for flushing and cleaning dirt, therefore, an opening is not required to be too large, the water inlet cross-sectional area of the first water inlet hole 401 is larger than that of the water outlet hole 403, intermittent water adding is carried out on the inside of the water heater through the sliding groove 1101 formed in the rotary disc 11, the water outlet amount of the water outlet hole 403 is reduced due to the fact that the water adding and discharging are not continuous, the elastic force of the pressure spring 13 is smaller than the water pressure of tap water externally connected with the water inlet 5, the curvature of the outer side arc surface of the top block 12 is the same as that of the outer ring of the rotary disc 11, when the top block 12 is located at the bottom, the rotary disc 11 can contract inwards under the pressure and can be rotated and can be compressed under the pressure of the water pressure and can be generated when the top block 12 is located at the bottom A quantity of water is stored in the chute 1101 and then as it rotates to the top position the pressure spring 13 pushes the top block 12 out of the way under pressure balance so that all the water in the chute 1101 enters the water heater interior.

Wherein, the top position of air vent 406 is circular-arc, bellows 14 and water storage chamber 405 intercommunication and inside fill water, piston 15 is certain angle form and the biggest angle of sliding downwards is the horizontality, just can not drive impeller 9 and rotate when flowing out a small amount of hot water through apopore 403, just need supply cold water in the inner bag through water storage chamber 405 in order to guarantee the inside water pressure of water heater, and still can fill up in water storage chamber 405 and bellows 14 when follow-up intaking through first inlet opening 401, the arcuation section through air vent 406 can restrict the slip of piston 15, guarantee that it has certain limit when being full of water, play the effect of protection.

Wherein, the outside inclined plane of dog rack 16 is towards the water flow direction, and the outside of dog rack 16 adopts piston seal cover to connect in adjusting air cavity 407 opening part, will be close to the inside compression of dog rack 16 of second inlet opening 402 and drive the dog rack 16 of opposite side to shrink simultaneously in adjusting air cavity 407 when water pressure increases, and the atmospheric pressure effect that adjusts the inside air cavity 407 when water pressure diminishes again makes dog rack 16 return again.

The working principle is that a heating switch is normally turned on to heat water in a water heater through a heating pipe 2, when the water heater needs to be used after heating is finished, a water outlet 6 is opened, the hot water flows down from a water outlet pipe 3 to enter a water outlet hole 403 under the action of water pressure and drives an impeller 9 to rotate, the impeller 9 drives a transmission shaft 10 to rotate when rotating, the transmission shaft 10 drives a rotary table 11 to rotate, a top block 12 of the rotary table 11, which is positioned at the bottom, is jacked to the innermost part of a sliding groove 1101 under the action of the water pressure, then the cold water enters the sliding groove 1101, the sliding groove 1101 which stores the cold water rotates to the top along with the rotation of the rotary table 11, the top block 12 is jacked outwards under the balance of the internal pressure of the water heater and under the elastic action of a pressure spring 13, and therefore the cold water entering from a water inlet 5 is guided into an inner container of the water heater;

when the incrustation scale needs to be cleared up, delivery port 6 is locked tightly this moment, therefore first inlet opening 401 can not intake equally, screw off the valve port of drain 7, sewage flows down from blowhole 404, cold water in the water inlet 5 enters into rotatory nozzle 8 through second inlet opening 402 this moment, then along with rotatory nozzle 8 to strike out all around thereby all around the incrustation scale in the inner bag washes away, thereby will inwards extrude dog rack 16 when external water pressure grow and drive the synchronous inside shrink of dog rack 16 of opposite side through gear 17, the inside opening aperture of blowhole 404 is bigger when rotatory nozzle 8's injection is more serious this moment, increase blowdown volume and blowdown speed, make dog rack 16 return under the atmospheric pressure effect in adjusting air cavity 407 after pressure has little.
