Abstract
The electric water heater for supplying both cold and hot boiled water is composed of water container, heating container, refrigerating container, heat-exchange container, cooling pipe, level and temp. sensors and control circuit. The hot boiled water in heating container is cooled via heat-exchange container and semiconductor refrigerator into cold one. The cold water to be heated in heat-exchange container is preheated by cooling tube in the container and heating surface of semiconductor refrigerator. The temp. and level is automatically regulated and compensated.
Description
The present invention relates to a kind of electronic installation that boiling water can be provided, except that hot boiling water is provided, more can provide cold water hot boiling water cooling.
Present known electronic water heater is to be made of a water container and a heater.Cold water is injected water container, connect heater power source, boiler enters heated condition, and after water temperature reached 100 ℃, the temperature control element action disconnected heater power source, and heater quits work, and boiler enters keeping warm mode.When because boiling water cool off naturally or make because of adding cold water after temperature drops to a predetermined value (as 85 ℃), the temperature control element action, connect heater power source, heater is started working, boiler enters heated condition again, reach till 100 ℃ up to water temperature, boiler enters keeping warm mode again again.What general electronic water heater provided all is hot boiling water, and temperature can not directly be drunk than higher, makes troubles to use.
The drinking device that the purpose of this invention is to provide a kind of cold, hot two-purpose, it can not only provide the hot boiling water that is higher than 85 ℃ (be used to infuse tea, towards milk, table-ware disinfection etc.), and can provide temperature at 20 ℃ to 30 ℃ cold water (generally drinking).
The object of the present invention is achieved like this: whole device by tank, heating container, heat exchange container, Refrigerating container, cooling tube, semiconductor cooler, heater, heating-up temperature sensor, cryogenic temperature sensor, high-order level sensor, low level level sensor, entering water electromagnetic valve, go out critical pieces such as water solenoid valve, hot water device for fetching water, cold water device for fetching water, control circuit board and constitute.
Tank links to each other with heat exchange container by tube connector; Heat exchange container links to each other with heating container by entering water electromagnetic valve; Heating container links to each other with the hot water device for fetching water by tube connector; Whole cooling tube is contained in the heat exchange container, and the one end links to each other with heating container by going out water solenoid valve, and the other end links to each other with Refrigerating container by tube connector; Refrigerating container links to each other with the cold water device for fetching water by tube connector.Heater cartridge is in the bottom of heating container, and its horizontal level is under hot water device for fetching water inlet.The outer wall of the tight obedient Refrigerating container of chill surface of semiconductor cooler, the outer wall of the tight obedient heat exchange container of its heating face.The heating-up temperature sensor is contained in the outer wall of heating container, and the cryogenic temperature sensor is contained in the outer wall of Refrigerating container.High-order level sensor is contained in the top of heating container, and the low level level sensor is contained in the bottom of heating container, and its horizontal level is on hot water device for fetching water inlet.
After the pressured difference of water in the tank enters the heat exchange container preheating, enter heating container by entering water electromagnetic valve.After the heating container moisturizing, connect heater power source, begin heating, the water in the heating container is heated to 100 ℃ after, continue heating a period of time again, to strengthen Disinfection Effect.Stop heating then, enter keeping warm mode.Add or hot boiling water cool off naturally and makes when being reduced to 85 ℃ under the water temperature as cold water, temperature sensor and control circuit make heater energising work, after water temperature reaches 100 ℃, continue to heat a period of time again, stop to heat, and enter keeping warm mode again.Through the hot boiling water of heating disinfection from go out water solenoid valve flow into cooling tube carry out heat exchange cool handle after, flow into again in the Refrigerating container, being further cooled becomes cold water.
Utilize heat balance principle, allow hot boiling water flow into thin and long cooling tube (as spiral or coiling formula), make it with heat exchange container in cold water to be heated have time enough to carry out heat exchange, temperature is reduced to 40 ℃ to 50 ℃, simultaneously the preheating of heating of the cold water to be heated in the heat exchange container.Refrigerating container is to freeze by the heat-absorbing action of the chill surface of the semiconductor cooler of tight its outer wall of card.When the water temperature in the Refrigerating container surpasses 30 ℃, by cryogenic temperature sensor and control circuit semiconductor cooler is started working, its chill surface absorbs heat to Refrigerating container, water temperature in Refrigerating container drops to till 20 ℃, by cryogenic temperature sensor and control circuit semiconductor cooler is quit work again, rise again until water temperature and just restart work above 30 ℃.The outer wall of the tight obedient heat exchange container of the heating face of semiconductor cooler, the heat that so not only makes semiconductor cooler generate in process of refrigerastion obtains in time and effectively distributing, but also can utilize these heats that the cold water to be heated in the heat exchange container is carried out preheating.
When the heating container middle water level dropped to the water level of low level level sensor qualification, control circuit cut out out water solenoid valve, opened entering water electromagnetic valve, and the cold water in the tank is added in the heating container by entering water electromagnetic valve through heat exchange container.
When the heating container middle water level was lower than the water level that high-order level sensor limits, not moisturizing immediately finished or water level when dropping to the water level that the low level level sensor limits just moisturizing up to water intaking in the water intaking process.
When the cold water of storing in the tank added to the water level that the low level level sensor of heating container bottom limits inadequately, control circuit stopped heater work, and sends the lack of water chimes of doom, lights the lack of water alarm lamp simultaneously, notifies the user to add water.
Entering water electromagnetic valve is normally closed, goes out water solenoid valve and often opens; When the needs moisturizing, close out earlier water solenoid valve, just open entering water electromagnetic valve then; Moisturizing finishes, and entering water electromagnetic valve recovers normally off; And finish to heating, going out water solenoid valve just recovers normally open, and the water that guarantees the inflow Refrigerating container like this is the hot boiling water through heating disinfection, rather than mixing water.
The horizontal level of hot water device for fetching water inlet is lower than level sensor but is higher than heater, causes damage with regard to having guaranteed heater can not surface like this.
The outer wall of heating container, Refrigerating container and heat exchange container is surrounded by insulation material, to strengthen insulation effect.A breather pipe all is equipped with at the top of heating container and Refrigerating container, directly reach tank top, keep normal atmospheric pressure in order to two containers, differential water pressures power is utilized, pack into umbrella shape permeability cell lid of the upper end of breather pipe is in case have in the cold water inflow pipe when adding water.Magnet is housed below heat exchange container, makes that the water in the heat exchange container passes through the magnetization of certain intensity, useful health.
Since adopt such scheme, the cold water that can when hot boiling water is provided, provide easy inlet easily to be absorbed by the body again, convenient and swift, energy savings.
The present invention is further described below in conjunction with drawings and Examples.
