Abstract
The utility model discloses an anti-freezing solar water heater, comprising a support and a water storage tank, wherein the water storage tank is provided with a water inflow and outflow pipe with functions of water inflow and water outflow. The water inflow and outflow pipe is inserted into an inner liner from the upper side of the water storage tank and is extended into the bottom part of the inner liner. The water inflow and outflow pipe is provided with a water inflow type mixing valve and is communicated with an air discharging pipe at the upper side of the water storage tank, and the air discharging pipe is provided with a control valve. After the anti-freezing solar water heater finishes using, the residual water in the water inflow and outflow pipe can be emptied in time by the matching operation of the water inflow type mixing valve and the control valve, so the frost cracking phenomenon of the pipe of the heater can be effectively prevented in winter, and the heater can realize running in four reasons and uninterrupted use.
Description
Technical field
The utility model relates to a kind of solar water heater, and the residual water in particularly a kind of pipeline of emptying in time effectively prevents the pipeline solar water heater of bursting by freezing in the winter time.
Background technology
At present, the downcomer of solar water heater is arranged on the bottom of storage tank, relies on the self gravitation of water to trickle in user family by drainage pipeline in the use.Because the restriction of structure, as long as in the storage tank water is arranged, water is arranged simultaneously also in the drainage pipeline, this kind situation is easy to take place the phenomenon of drainage pipeline bursting by freezing in the winter of cold, causes certain loss to the user.Therefore, the user has in the winter time with the water emptying in the storage tank, causes solar water heater idle in the winter time.
The utility model content
The purpose of this utility model is to provide a kind of anti-freezing solar water heater, and this kind solar water heater still can normally use in the winter of cold, and has advantage simple in structure, easy to use.
The utility model for achieving the above object, the technical solution of employing:
A kind of anti-freezing solar water heater comprises support and storage tank, and storage tank is furnished with the upper and lower conduit of the last water and the function of subdominant chord, and described upper and lower conduit inserts inner bag by the storage tank top and extends to the inner bag bottom, and upper and lower conduit is furnished with last water type and mixes water valve; Upper and lower conduit is communicated with bleeder pipe above storage tank, bleeder pipe is furnished with by-pass valve control.
Only also be provided with the check valve of water pipe one side conducting up and down on the above-mentioned bleeder pipe.
Above-mentioned upper and lower conduit stretches into the end of inner bag apart from 10 millimeters of inner bag bottoms.
Above-mentioned storage tank bottom is provided with standby water inlet pipe and water outlet pipe.
The beneficial effects of the utility model: this kind anti-freezing solar water heater, use the residual water in the compounding practice emptying in time upper and lower conduit that finishes to mix water valve and by-pass valve control by last water type in the back, prevent that effectively water heater pipeline from the phenomenon of bursting by freezing taking place in the winter time, can realize four seasons operation, the uninterrupted use.In addition, the check valve of water pipe one side conducting up and down only is set on bleeder pipe, plays dual fail-safe control, water is timely at present to guarantee water.
Description of drawings
Fig. 1 is the structural representation of anti-freezing solar water heater.
Below in conjunction with accompanying drawing the utility model is elaborated:
The specific embodiment
In conjunction with Fig. 1, a kind of anti-freezing solar water heater comprises support and storage tank 1, and storage tank 1 is furnished with the upper and lower conduit 2 with the last water and the function of subdominant chord, described upper and lower conduit 2 inserts inner bag by storage tank 1 top and extends to the inner bag bottom, and its end is apart from 10 millimeters of inner bag bottoms.Upper and lower conduit 2 is furnished with last water type and mixes water valve 3, and upper and lower conduit 2 is communicated with bleeder pipe 4 above storage tank 1, and bleeder pipe 4 is furnished with by-pass valve control 5.Only also be provided with the check valve 6 of water pipe 2 one side conductings up and down on the bleeder pipe 4.Be provided with standby water inlet pipe and water outlet pipe 7 in storage tank 1 bottom.
Above-mentioned upper and lower conduit 2 and bleeder pipe 4 insert in the user family when mounted, and last water type mixes water valve 3 and by-pass valve control 5 also is installed in the user family.
On solar water heater during water, will go up the water type and mix water valve 3 handles and rotate to water level and put water.Close water supply valve after water is full, open by-pass valve control 5 (vent valve) venting simultaneously, and will go up the water type and mix water valve 3 handles and rotate to hot water end maximum position and open, the water in the upper and lower conduit 2 is because of the emptying of self gravitation effect nature.
When the solar water heater water, closing control valve 5 (vent valve), to go up the water type mixes water valve 3 handles and rotates to water level and put water, and then will go up the water type and mix water valve 3 handles and rotate to the hot water end position and open and freely regulate, so that obtain the hot water (this process has been utilized siphon principle physically) of preference temperature.Water finishes, and opens by-pass valve control 5 venting, and will go up the water type and mix water valve 3 handles and rotate to hot water end maximum position and open, and the water in the upper and lower conduit 2 is because of the emptying of self gravitation effect nature.
Check valve 6 on the bleeder pipe 4 plays the dual fail-safe effect, makes siphon more effective, and has guaranteed anhydrous immersion in the bleeder pipe 4, and is more safe and reliable.
Certainly; above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present utility model also should belong to protection domain of the present utility model.
