Abstract

The utility model relates to a water saving device for solar water heater, which comprises a water tank, a water feeding pipe, a drain pipe, a tap water pipe, a water feeding valve, a hot water pipe, a cold water pipe, a water mixing valve and an air outlet. The water feeding valve is arranged at the joint position of the tap water pipe, the water feeding pipe and the drain pipe. A water storage tank is connected and arranged between the water feeding pipe and drain pipe and the cold water pipe for showering; a drain valve is arranged at the communication position of the water storage tank, the water feeding pipe and drain pipe. The bottom of the water storage tank is connected with the cold water pipe through a water check valve and a reducing tee; the pipeline of the hot water pipe is higher than the pipeline of the cold water pipe. A three-way solenoid valve is connected and arranged between the water feeding pipe and drain pipe and a solar water tank. When the water is not in use, the three-way solenoid valve is controlled to automatically drain the cold water in the water pipe into the water storage tank so as to empty the water feeding pipe and the drain pipe for avoiding frost crack and waste. When a shower is taken, the hot and cold water together enter the water mixing valve. The hot water comes from a heater water tank on the roof and the cold water comes from the tap water pipe and the water storage tank, thereby achieving comfortable shower condition. The water saving device for solar water heater has the advantages of simple structure, convenience and practicality, reasonable process, easy and simple operation, etc.

Description

Automatic regulating device for solar water heater

Technical field

The utility model relates to a kind of shower set, especially a kind of water saving fixtures of solar water heater.

Background technology

At present, solar water heater has become important bathing instrument in the life at home., the water tank of solar water heater is installed in roof, and has bigger distance between the indoor shower nozzle, and connects by water pipe between this segment distance, can't increase temperature, so water temperature is lower in this section water pipe.Therefore, all need to open shower nozzle and emit cold water in this section water pipe earlier when each bathing, the hot water in the solar water heater water tank could flow out then, thereby all can cause the waste of about 3 premium on currency when bathing at every turn; In addition, this section water pipe is laid on outdoor as tube connector, is easy to take place bursting by freezing in the winter of cold, also needs more water-changing tube, very inconvenience when serious.In order to address the above problem, we provide a kind of new-type solar water heater that can directly emit hot water.

Summary of the invention

The purpose of this utility model provides a kind of automatic regulating device for solar water heater, is used to solve the problem that needs to bleed off cold water before the shower of regular solar water heater.

For achieving the above object, the utility model automatic regulating device for solar water heater, comprise solar water container, upper and lower conduit, running water pipe, water supply valve, shower hot-water line, shower cold water pipe, mixed water valve and the gas outlet that is opened in the solar water container end face, shower hot-water line one end communicates with upper and lower conduit, and the other end communicates with mixed water valve; Shower cold water pipe one end communicates with running water pipe, and the other end communicates with mixed water valve; Water supply valve is installed in running water pipe and upper and lower conduit junction, between upper and lower conduit and shower cold water pipe, be connected and installed storage tank, with the upper and lower conduit place of connection drain valve is installed at storage tank, the storage tank bottom is connected with the shower cold water pipe with reducing tee by water check valve; Shower hot-water line pipeline is higher than shower cold water pipe pipeline; Be connected in series the installation three-way magnetic valve with the solar water container junction at upper and lower conduit.

After adopting said structure, when stopping water, the control three-way magnetic valve, the cold water in the water pipe can enter automatically and be installed in indoor storage tank, and making does not have water in the upper and lower conduit, not only can avoid bursting by freezing but also can avoid waste; When opening when mixing the water valve shower, hot water and cold water enter mixed water valve jointly, and hot water is from the water-heater water tank on roof, and cold water is realized comfortable bathing condition from running water pipe and storage tank.Why water in the storage tank can be got up by belt and be applied, then be because used " Bernoulli equation " principle, combine by " Bernoulli equation " principle and check valve, thereby do not need external force just can successfully solve the application problem that returns of emptying cold water.

Compared with the prior art, the beneficial effects of the utility model are: simple in structure, convenient and practical, technology is reasonable, easy and simple to handle, can save water resource, avoid waste.

Description of drawings

Fig. 1 is the overall structure schematic diagram of the utility model automatic regulating device for solar water heater.

Number in the figure: 1 is that solar water container, 2 is that upper and lower conduit, 3 is that running water pipe, 4 is that water supply valve, 5 is that shower hot-water line, 6 is that shower cold water pipe, 7 is that mixed water valve, 8 is that gas outlet, 9 is that storage tank, 10 is that drain valve, 11 is that water check valve, 12 is reducing tee, 13 three-way magnetic valves.

The specific embodiment

As shown in Figure 1, the utility model automatic regulating device for solar water heater, comprise solar water container 1, upper and lower conduit 2, running water pipe 3, water supply valve 4, shower hot-water line 5, shower cold water pipe 6, mixed water valve 7 and the gas outlet 8 that is opened in solar water container 1 end face, shower hot-water line 5 one ends communicate with upper and lower conduit 2, and the other end communicates with mixed water valve 7; Shower cold water pipe 6 one ends communicate with running water pipe 3, and the other end communicates with mixed water valve 7; Water supply valve 4 is installed in running water pipe 3 and upper and lower conduit 2 junctions, between upper and lower conduit 2 and shower cold water pipe 6, be connected and installed storage tank 9, with upper and lower conduit 2 places of connection drain valve 10 is installed at storage tank 9, storage tank 9 bottoms are connected with shower cold water pipe 6 with reducing tee 12 by water check valve 11; Shower hot-water line 5 pipelines are higher than shower cold water pipe 6 pipelines; Be connected in series installation three-way magnetic valve 13 with solar water container 1 junction at upper and lower conduit 2.Wherein, the suction journey of this device can reach about 63cm, and water absorption is 2.0Kg/min, experimental results show that it is practicable that the cold water that utilizes in this scheme realization solar water heater water pipe turns back in the bathing pipeline.On using, this device has been realized the hope that people " open the shower nozzle water valve hot water is just arranged "; Aspect resource, this device has also been realized the saving of water resource and recycling.
