Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Novel storage-type electric water heater comprises storage tank, insulating foam layer 12, the unidirectional non-return valve 8 of water inlet, entering water electromagnetic valve 1, water inlet pipe 17, outlet pipe 18, multichannel water supply interface 14, hot and cold water control valve 13 and heater 10, cooling-water temperature sensor 9, controller.
Two level sensors 11 are installed on the inner bag 19 of storage tank; Level sensor 11 can send signal to controller when water level reaches A or B water level.
The exhaust gear that comprises blast pipe, exhaust solenoid valve 2 is installed at the top of storage tank; Pressure limiting valve 3 also is housed on the blast pipe.
The admission gear that comprises air inlet pipe, air inlet magnetic valve 4 and air accumulator 15 also is installed at the top of storage tank; Unidirectional non-return valve 5 also is housed on the air inlet pipe, air accumulator 15 1 sides are equipped with unidirectional non-return valve 16 and air pump 6, air pump 6 can be inflated to air accumulator 15, opposite side is equipped with baroswitch 7, in order to detect the air pressure in the air accumulator 15, when the air pressure in the air accumulator 15 sets value less than baroswitch 7, the contacting of baroswitch 7, when the air pressure in the air accumulator 15 set value greater than baroswitch 7, the contact of baroswitch 7 disconnected.Air pump 6 is subjected to baroswitch 7 controls, the contacting of baroswitch 7, and air pump 6 is started working, and the contact of baroswitch 7 disconnects, and air pump 6 quits work, and water heater is started working, and baroswitch 7 begins to control air pump to air accumulator 15 superchargings.The setting value of baroswitch 7 is less than the rated value of pressure limiting valve, for example: the pressure limiting valve rated value is 0.15MPa, the setting value 0.1Mpa of baroswitch.
The course of work of this water heater is such, at first water inlet pipe 17 and running water pipe is connected, and closes hot and cold water control valve 13, sets the water level that will intake on the controller of water heater, and establishing water level is A, and water temperature, and water heater is started working.At first controller opens entering water electromagnetic valve 1, exhaust solenoid valve 2, water through unidirectional non-return valve 8, enters inner bag 19 from entering water electromagnetic valve 1, and the air in the inner bag 19 is discharged from electromagnetic exhaust valve 2.When water level rose to A, level sensor 11 sent signal to controller, and entering water electromagnetic valve 1 is closed, and stops into water.Heater 10 energising beginning heating detects water temperatures by cooling-water temperature sensor 9, and when water temperature reaches design temperature, controller cuts out exhaust solenoid valve 2, heater 10.Then, controller opens air inlet magnetic valve 4, the gas in the air accumulator 15 is from air inlet magnetic valve 4, arrive in the inner bag 19 through unidirectional non-return valve 5, inner bag 19 internal gas pressures rise rapidly, open hot and cold water control valve 13 this moment, and the air pressure in the inner bag is discharged hot water from hot and cold water control valve 13.
After the water heater energising, baroswitch just begins to control air pump 6 work, keeps air pressure in the air accumulator 15 at 0.1MPa.
If required water level is made as B, water heater working process and above-mentioned situation are basic identical, and after water heater was started working, when water level rose to B, level sensor 11 sent signal to controller, and controller turn-offs entering water electromagnetic valve 1, stops into water.All the other processes are the same.
This water heater can also be the same with common closed water heater, makes the inner bag water level remain on a certain water level always, and hot water is provided continuously, realizes that multichannel supplies water.Its course of work is: at first set required water level on controller, as A water level, heating-up temperature; Then, entering water electromagnetic valve 1 is opened into water under controller action.At this moment, exhaust solenoid valve 2 is not worked always, but by the pressure limiting valve exhaust, along with water level constantly rises, inner bag air pressure constantly increases, when air pressure surpasses the rated value (as 0.15MPa) of pressure limiting valve 3, pressure limiting valve 3 is opened, and the air in the inner bag 19 is discharged from pressure limiting valve 3.When the inner bag water level arrives A, level sensor 11 sends signal to controller, entering water electromagnetic valve 1 is closed under controller action, stop into water, controller makes heater 10 begin heating simultaneously, when water temperature arrived set water temperature, controller made heater 10 stop heating, and then air inlet magnetic valve 4 is opened under controller action.Open hot and cold water control valve 13 this moment, and hot water just can be discharged from outlet pipe by inner bag air pressure.When water level was lower than setting value A, controller made entering water electromagnetic valve 1 open into water, reaches A up to water level, and level sensor 11 outgoing signals, controller are closed entering water electromagnetic valve 1.When being reduced to setting value under the water temperature, controller makes heater 10 begin heating, and when water temperature rose to setting value, heater 10 stopped heating work, is keeping the hot water of designated water level, water temperature in the water heater liner always.
When this kind mode was worked, water source hydraulic pressure should be greater than the rated value (as 0.15Mpa) of pressure limiting valve 3, and the hydraulic pressure of running water all can meet the demands usually, if water source hydraulic pressure is too little, need install booster pump additional.After the water heater energising, just baroswitch 7 begins to control air pump 6 to air accumulator 15 superchargings, the air pressure that air accumulator 15 is kept is exactly the setting value (as 0.1Mpa) of baroswitch in addition.
