Abstract

The utility model discloses a water controlled siphon-type freeze proof solar water heater, which solves the problem that an outdoor pipeline is frozen when a traditional solar water heater is used in winter. Exhaust pipes 4 are arranged on an upper and a lower water pipes 2. An overflow pipe 6 connected with a water controlled pipe 3 is also arranged. The exhaust pipes 4 are also connected to the water controlled pipe 3. Connection positions between the exhaust pipes 4 and the water controlled pipe 3 are at the same height with the bottom of a water storage tank 1. The top end of the water controlled pipe 3 is opened. A water faucet 8 and a valve 11 are arranged at the bottom of the water controlled pipe 3 and are connected with a cold water inlet pipe 5. The realization and the failure of the siphon action of the upper and the lower water pipes 2 can be controlled by utilizing a mode that an interfaces of the exhaust pipe 4 is blocked and opened according to a water level in the water controlled pipe 3. Water in pipelines can be finally emptied. Thereby, pipeline freezing in winter can be prevented. The utility model has the advantages of simple structure and rapid and thorough evacuation.

Description

Water control hydrocone type anti-freezing solar water heater

The utility model relates to solar water heater, particularly water control hydrocone type anti-freezing solar water heater.

Prior solar water heater mostly adopts the hydrocone type diversion, reaches the purpose of bathing, discharges water, diversion all utilizes same upper and lower conduit, because the storage tank shelf is outdoor, upper and lower conduit must have one section be positioned at outdoor, to winter, if not emptying upper and lower conduit certainly will cause freezing accident.Chinese patent 992060605 discloses a kind of anti-freezing solar water heater, and its adopts branch road water pipe cooperation evacuation and anti-freezing that is connected with water inlet pipe and water outlet pipe, and its emptying time is long, unstable properties, and can not be emptied completely, can not effectively prevent the generation of freezing accident.

The purpose of this utility model is in order to overcome the shortcoming of existing apparatus, provide a kind of easy to operate, intestine evacuation velocity fast, the water control hydrocone type anti-freezing solar water heater that can effectively be emptied completely.

For achieving the above object, the utility model is by the following technical solutions:

A kind of water control hydrocone type anti-freezing solar water heater, on storage tank, add the upper and lower conduit of hydrocone type, the upper and lower conduit bottom is connected with cold water inlet, the shower delivery port is installed on the cold water inlet of upper and lower conduit one side, the upper end that it is characterized in that upper and lower conduit also is connected to a blast pipe, top, side at storage tank is connected to an overflow pipe, its outlet connection one water control pipe straight up and down, water control pipe upper end is higher than storage tank top and opening, is connected with cold water inlet in the inlet chamber of lower end; Blast pipe is connected with the water control pipe, and the junction is concordant with the bottom of storage tank, and blast pipe top also is provided with a non-return valve, and direction is towards storage tank; The lower end of water control pipe also is provided with water nozzle, is provided with valve between water nozzle and cold water inlet; The upper and lower conduit lower end also is provided with valve, is positioned on the cold water inlet between upper and lower conduit and water control pipe to be provided with another valve.

Be positioned at the valve upside on the described upper and lower conduit and be provided with a flowmeter.

The utility model is connected together blast pipe, overflow pipe, water control pipe, thereby and do not influencing under the siphon situation establishing non-return valve between blast pipe and upper and lower conduit, in case want emptying, only need open water nozzle, the water in can each water pipe of emptying in 1 minute, thus it is fast to have an intestine evacuation velocity, emptying completely, and easy to operate advantage, it is simple in structure simultaneously, low cost of manufacture.

Below in conjunction with drawings and Examples the utility model is described in further details.

Fig. 1 is the utility model overall structure schematic diagram.

As shown in FIG., this water control hydrocone type anti-freezing solar water heater, utilize prior solar water heater, on its storage tank 1, add the upper and lower conduit 2 of hydrocone type, upper and lower conduit 2 bottoms are connected with cold water inlet 5, shower delivery port 9 is installed on the cold water inlet 5 of upper and lower conduit 2 one sides, the upper end of upper and lower conduit 2 is connected to blast pipe 4, is connected to overflow pipe 6 on the top, side of storage tank 1, and its outlet is connecting straight up and down a water control pipe 3, water control pipe 3 upper ends are higher than storage tank 1 top and opening, be connected with cold water inlet 5 in the inlet chamber of lower end, blast pipe 4 is connected with water control pipe 3, and the junction is concordant with the bottom of storage tank 1, blast pipe 4 tops also are provided with non-return valve 7, direction is towards storage tank 1, in case up and down during water, in case storage tank 1 water full after, blast pipe 4 and overflow pipe 6 whole water-fillings cause water control pipe 3 to lose efficacy.The lower end of water control pipe 3 also is provided with

water nozzle

8, and 5 of water nozzle 8 and cold water inlets are provided with valve 11, and the lower end of upper and lower conduit 2 also is provided with valve 10, and its upside is provided with flowmeter 13, is positioned at 3 of upper and lower conduit 2 and water control pipes on the cold water inlet 5 and is provided with another valve 12.

During use, if want water, then close water nozzle 8, open valve 11, cold water enters water control pipe 3, when water level surpasses the junction of blast pipe 4 and water control pipe 3, and valve-off 11; Then,

open valve

10,12, cold water enters upper and lower conduit 2, when water level rises about 50-100 centimetre the time, valve-off 12 is opened shower opening 9, just can utilize siphon principle with the water sucking-off in the storage tank 1, flow out along upper and lower conduit 2, the temperature that flows out water is regulated by valve 12.

When time spent not, evacuation and anti-freezing, water nozzle 8 can be opened, water level in the water control pipe 3 descends rapidly, and is lower than the junction of blast pipe 4 and water control pipe 3, and the air opening on keyholed back plate 3 tops downstream enters blast pipe 4, entering upper and lower conduit 2 by non-return valve 7 lost efficacy the siphon of upper and lower conduit 2, water is wherein discharged from shower opening 9 rapidly, finishes the emptying of whole yard piping, and the time can be above 1 minute.

If will in storage tank 1, add water, then open water nozzle 8, valve-off 11 is opened

valve

10,12 along water on the upper and lower conduit 2, after storage tank 1 water is full, along overflow pipe 6 overflows, and flows out from water nozzle 8, judges that water outlet is full, and then valve-off 12,10, stop to add water.If add water winter, then utilize purging method, with tube emptying, freeze to prevent yard piping, if can cooperate flowmeter 13 to add water other season, and will the 3 water emptyings of water control pipe.
