Abstract

The utility model belongs to an automatic thermodynamic controller for a water heater, comprising an upper limit valve, a lower limit valve, a hot water valve, a magnetic valve, a driver, a temperature control unit and connecting pipes. The water heater provided with the controller can automatically supply water and stop water, and water can automatically drain after heated to a preset temperature. Cold water can stop supplying during the process of hot water with preset temperature drained until a preset lower limit height, and therefore, drained water is not mixed by the cold water and the hot water. When the water heater is communicated with an accumulator, the cold water and the hot water can be supplied continually and circularly, and the problem of the hot water falling short of demand in busy use is solved.

Description

Automatic thermodynamic controller for water heater

The utility model belongs to the water heater automatic controller, and is especially relevant with the heating power automatic controller.

Water heater controller commonly used at present generally can be accomplished can go up cold water automatically after boiling water in the water heater is put into certain low level; After water to be heated was opened, people can take boiling water, and water level drops to water inlet automatically again behind the low level of setting.The weak point of this quasi-controller is to discharge hot water or boiling water when water is heated to design temperature automatically.

The purpose of this utility model is will design a kind ofly can go up cold water automatically, can discharge the water heater heating power automatic controller that is heated to design temperature hot water again automatically.

Temperature control unit 6 by the control lever 32 of an end band guide wheel 31, be fixedly connected on control panel 33 on the control lever 32, be installed in the control lever two ends 34,35 and two pairs of

guide wheels

36,37 of baffle plate, be sleeved on control panel 32 outer return spring 38 and memorial alloy control springs 39 and form.Control lever is a column, and with valve drive rod 23 approximate vertical of actuator, the pinch roller 31 of end just in time is pressed in when cold water temperature on the drive plate 24 of actuator.Control lever both sides vertically are fluted, and two pairs of

guide wheels

36,37 fit in the groove, and two pairs of guide wheels are installed in respectively on the wheel frame, and wheel frame is fixedly mounted on the installing plate 40, and control lever can only be along bar to moving.Control panel 33 is welded on the middle part of control lever, memorial alloy control spring 39 is sleeved on the control lever between the baffle plate 34 of control panel 33 and band guide wheel 31 sides, return spring 38 is sleeved on the control lever between control panel 33 and the other end baffle plate 35, the phase transition temperature of memorial alloy control spring is higher than the phase transition temperature that memorial alloy drives spring, the temperature that concrete material can be controlled as required is selected, for example select for use phase transition temperature about 80 ℃ and about 60 ℃ Cu-Zn-Al memory alloy wire is made memorial alloy control spring respectively and memorial alloy drives spring, then can be when water temperature reaches 80 ℃ automatic hot-water supply.Actuator and temperature control unit can be arranged on the lower position of water heater.

During use, as begin to install in the water heater of this controller when anhydrous, limit valve 1 up and down, 2, all be in open mode, memorial alloy control spring and memorial alloy drive spring and are in the normal state entirely, under the effect of each return spring, the guide wheel 31 of control lever 32 front ends is positioned on the drive plate 24, therefore hot water valve 3 is in closed condition, the outer magnet 19 of drive rod 23 ends is positioned at the side of inner magnet 17 at this moment, interior outer magnet is inhaled mutually, thus make inner magnet also be in open mode away from the water inlet magnetic valve in cold water inlet road 16, can be if open the cold water feed cock this moment from last, enter cold water in the lower limit valve, when the water level in the water heater reaches the height of lower limit valve 2, the lower limit valve promptly cuts out automatically, and other valve is constant, and the upper limit valve cuts out automatically when water level reaches the height of upper limit valve 1, other valve is constant, the water heater heating.When water temperature reached the temperature of memorial alloy driving spring in the actuator, memorial alloy drove spring and just should extend, but because control rod end guide wheel 31 is pressed on the drive plate 24, was in the energy storage state so memorial alloy driving spring can't extend.When water temperature reaches the transition temperature of memorial alloy control spring in the temperature control unit, during the temperature of the water of i.e. desire control, memorial alloy control spring 39 promptly extends, promote control panel 33, and control lever 32 bars that drive and control panel 33 are fixed together are to moving, make the guide wheel 31 of end leave drive plate 24 on the actuator, the memorial alloy that has contained enough energy this moment drives the i.e. elongation fast of spring, depression bar in the hot water valve that one side drives with drive plate links to each other is opened hot water valve and is outwards discharged hot water; On the other hand another outer magnet 20 is shifted onto the position adaptive with inner magnet 17, because outer magnet 20 and inner magnet polar repulsion, so inner magnet 17 is pushed to the water inlet of cold water inlet 16, tamponade 18 is pressed in magnetic valve cuts out, when the hot water position in the water heater is lower than the upper limit valve, the upper limit valve is opened, so but can not advance cold water because magnetic valve is the water inlet of the upper limit valve of cutting out, so will never mix cold water in the hot water of emitting, when the water level in the water heater reaches the lower limit valve, the lower limit valve is opened, and enters cold water from the lower limit valve, and the memorial alloy that cold water flings in the actuator drives spring, its temperature is dropped to below the phase transition temperature, memorial alloy drives spring and shrinks, and the while under the effect of return spring 27, is pushed drive plate 24 to memorial alloy and drives spring again.Driving on the one hand depression bar 13 this moment moves and hot water valve is closed, make drive rod 23 make bar on the one hand again to moving, make another outer magnet 19 of rod end adaptive with inner magnet 17, outer magnet 19 is inhaled mutually with inner magnet 17 polarity, make tamponade 18 away from cold water inlet, thereby open magnetic valve, the upper limit valve just can above water like this.Also cooling gradually of memorial alloy control spring in last water process outside the control lever 32, reach phase transition temperature when following, memorial alloy control spring shrinks, under the effect of return spring 38, push control lever 32 to actuator again, the pinch roller 31 of its end is pressed in again on the drive plate 24 of actuator, and hot water valve is closed reliably, so generally speaking, the installation site of actuator and temperature control unit should be lower than the installation site of lower limit valve, in time closes reliably to guarantee hot water valve.Repeated to begin the into state of cold water so again.The design's water heater heating power automatic controller is gone up cold water like this repeatedly circularly automatically, is heated to behind the design temperature discharging hot water or boiling water automatically, reaches automation fully.

The design's water heater heating power automatic controller can with various water heaters and the supporting use of water boiler, the water heater that is particularly suitable for solar energy heating uses, and makes it to become unwatched automatic boiler.The water heater that the design's controller is housed can be gone up cold water and discharging hot water automatically, therefore, can not boil boiling water for a long time repeatedly, both saved the energy, body health benefits again, will never advance cold water in discharging hot water process, the boiling water of emitting can not be the mixing water of cold water and boiling water, has guaranteed the quality of drinking water.Water heater that this controller is housed with after cistern is communicated with, can be stored the hot water or the boiling water of a great deal of, to solve the water use peak problem that supply falls short of demand.
