Abstract
The water heater comprises a tank having heating elements (2, figure 1), an inlet and outlet pipe (3,4, figure 1), a control mechanism (5, figure 1) and a rotating bracket 58. The mechanism controls power to the elements and includes a first 51, second 52 and third 53 housing. The first housing has a water inlet 511 connected to the inlet pipe, a water outlet (512, figure 3) connected to the water tank, and a first 54 and second 542 watertight ring. The first ring allows water flow between the inlet and outlet when in a first position proximate a base plate 50 and prevents water flow when in a second position distal the base plate. An aperture (541, figure 6) in the first ring permits water flow into an inner cavity. The second ring is movable in/out of the cavity and actuates the bracket via a locating assembly 56, compression plate 565 and T-bar 566. The second housing has a chamber defined by a diaphragm 57 operable to actuate the bracket via ejector pins 572. The bracket is hinged and rotates under the influence of the pins and T-bar to contact micro-switches (591, figure 7) that toggle the heating elements power on/off.

Principles of the present embodiment are as follows: Under initial status, outlet pipe 4 doesn't have water flow out, two heating elements 2 are not energized, first watertight ring 54 fitted on the first housing 51 is at upper position, which separates first housing 51's water inlet channel 511 and water outlet channel 512, water goes through water hole 541 above first watertight ring 54's surface and fulfill first housing 51's inner cavity below first watertight ring 54, also ejector pin 55 is at the upper position, ejector pin 55's bottom seal plug 551 blocks second watertight ring 542's central hole.
When fan shape plate 5311 at spindle 531's bottom not match with sockets 5831 at two rotary brackets 58's right bottom, two rotary brackets 58 can rotate, press plate 565, plate 565 will drive compression bar 564 and ratchet 562 matching, so that ejector pin 55 move downwards and fixing, seal plug 551 at ejector pin 55's bottom can open second watertight ring 542's central hole, through second watertight ring 542's central hole, water inside first housing 51's inner cavity that belows first watertight ring 54 can goes through second watertight ring 542's central hole and flows from first housing 51's water outlet channel 512, flow control valve 6, then flows into water tank 1, water pressure above first watertight ring 54 then is higher than water pressure under the first watertight ring 54, therefore water pressure rapidly drives first watertight ring 54 move downwards, connects first housing 51's water inlet channel 511 and water outlet channel 512, also, second housing 52's inner cavity above impermeable membrane 57, due to connection with first housing 51's water outlet channel, water also flows in, water pressure drives impermeable membrane 57 deforms downwards, impermeable membrane 57 then drives ejector pin jacket 571 and two ejector pins 572 move downwards, two ejector pins 572 drive two rotary brackets 58's left bottom end 582 respectively, and let two rotary brackets 58 rotate anti-clockwise, two rotary brackets 58's right bottom end 583 push two microswitches 59's contacts 591, two microswitches 59 then connect two heating elements 2's power supply at the same time, then two heating elements 2 heat water inside water tank 1, water outlet pipe 4 then can release hot water.
When requires to stop hot water, press plate 565, plate 565 drives pressing bar 564 to match with ratchet 562, under compression spring 563's working, compression bar 564 and ejector pin 55 move upwards and positioning, compression bar 564 drives pressing plate 565 and two T shape bars 566 move upwards and positioning, two T shape bars 566 then drives rotary bracket 58's left top part 581 to make two rotary brackets 58 rotation clockwise, two rotary brackets 58's right end 583 then leave away from two microswitches 59' contacts 591, two microswitches 59 then cut off two heating elements 2' electricity, at the same time, ejector pin 55's bottom seal 551 block second watertight ring 542's central hole, water in first housing Si's water inlet channel 511 then gradually fill water to first housing Si's inner cavity that under first watertight ring 54 through water hole 541 above first watertight ring 54's surface. During water filling process, first watertight ring 54 moves up gradually, when first watertight ring 54 moves to right position, first housing 51's water inlet channel 511 and outlet channel 512 will be separated, which delays water shut down, through this function, residual heat on the heating elements 2 will be removed and prevent scalding.
When fan shape plate 5311 at the spindle 531's bottom is matching with socket 5831 below one rotary bracket 58's right bottom 583, stuck rotary bracket 58 cannot rotate, microswitch 59 relates to rotary bracket 5 cannot work, heating element 2 controlled by niicroswitch 59 will not electrified, therefore use rotation spindle 531 can select heating power.
Above is only a preferred example of this invention, technical people in this industry according to request to claim equivalent changes fall within the scope of protection of this case.
