Description
Technical field
The present invention relates to a kind of total head Full-automatic hot-water device.
Background technology
Winter heat supply water is that the people's livelihood of the northern area of China one of ensures.Different according to energy obtain manner, hot-water supply system can be divided into two kinds, boiler heat supplying water and solar-heating water.Wherein, boiler heat supplying water both can obtain heat energy by coal-fired, fuel mode, also can obtain energy by Electric heating, and boiler heat supplying water is the major way of present China Winter heat supply water.The drawback of boiler heat supplying water is to need to consume non-renewable resources, and obtains a large amount of pollutants of meeting generation in the heat process, has caused serious environmental pollution.Solar-heating water generally comprises the first heat exchange tank by solar water heater circulation heating water, and the recirculated water in the first heat exchange tank is supplied with the user by the water pump pressurization is rear, thereby realizes utilizing the purpose of solar-heating water.Although traditional solar-heating water device does not consume non-renewable energy resources, but the solar heat of its collection need to be by supplying with the user after the water pump pressurization, therefore not only need people manually to control, and need to consume extra electric energy, caused energy-conservation the economize on electricity or energy-conservation drawback of not saving money.Moreover,, because winter temperature is lower, cause the initial temperature of recirculated water in tank body too low, so the heat time heating time of traditional solar-heating water device is all long, causes the supplying hot water effect poor.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of rational in infrastructure for above-mentioned deficiency, need not Artificial Control pressurization, tank body just can pressurize supplying hot water and total head Full-automatic hot-water device easy to use.
For solving the problems of the technologies described above, this total head Full-automatic hot-water device comprises the tank body that is connected with running water pipe, its design feature is that described hot water apparatus also comprises the heating arrangements that is connected with tank body, the hot-water line that is deep into tank inner chamber is installed on tank body, the inner extending end of hot-water line extends to the top of tank inner chamber, and the overhanging end of hot-water line is equipped with hot water valve.
Adopt said structure, the hot-water line inner extending end extends to tank inner chamber top, the hot-water line overhanging end is equipped with hot water valve, tank inner chamber is the hermetically-sealed construction that is connected with running water pipe, the height of hot-water line the inner is far above the height of running water pipe the inner, heating arrangements can heat the running water in tank body, and the running water after being heated upwards flows, like this with regard to making that upper water temperature in tank body is higher and lower floor's temperature is lower.So, when opening hot water valve, be exactly hot water after being heated from what flow out in hot-water line, and be the highest running water of temperature in tank body.Along with the outflow of hot water, in tank body, hydraulic pressure reduces, and the running water in running water pipe can be charged in tank body by automatic makeup, therefore need not to add water pump pressurization supplying hot water, not only saves cost, and has reduced power consumption, and is very easy to use.
As a kind of implementation, described heating arrangements comprises and is located at the first heat exchange tank in tank body and is located at the solar heat-exchange mechanism that tank body is outer and with the first heat exchange tank, be communicated with.Described solar heat-exchange mechanism is boiler or the solar thermal collector of solar water heater.Adopt clean energy resource solar energy as heating arrangements, use very convenient and energy savings, carry out heat exchange by the first heat exchange tank, can select the first heat exchange tank directly is communicated with domestic solar water heater's boiler, perhaps the choice for use solar thermal collector gathers solar energy, structure is all simple, and it is convenient to realize.
As further implementation, described heating arrangements also comprises and is located at the second heat exchange tank in tank body and is located at source, the ground heat exchange mechanisms that tank body is outer and with the second heat exchange tank, be communicated with.
