Though there are a lot of researchs that water-saving device of water heater is constantly improved technically at present; For example Chinese patent number is that 201020186915.3 utility model patent adopts that the n type is curved to realize the collection of this a part of cold water with storage tank; Also having Chinese patent number is the patent of invention of 200710032339.X; The mode that employing is provided with water pump realizes the backflow of cold water, but these researchs all exist the complexity that has increased system, and cost is higher; Be difficult for shortcomings such as popularization, the requirement of " energy-saving and emission-reduction, the recycle " advocated instantly with country is not inconsistent.
Summary of the invention
The object of the present invention is to provide a kind of water heater backflow water saving fixtures, solve when using water heater at every turn, just have hot water to flow out after the cold water in the water heater pipelines such as needs has flowed, and the problem that this part cold water is wasted usually.
Another purpose of the present invention is to provide a kind of water heater backflow water saving fixtures, under the prerequisite of not destroying the original function of shower utensil, water saving fixtures of the present invention is installed, and the user can select to use as required.
A purpose more of the present invention is to provide a kind of water heater backflow water saving fixtures, solves the existing existing needs of water saving fixtures additionaling power equipment (like water pump), the high problem of energy consumption are provided.
For reaching above purpose, the solution that the present invention adopted is:
A kind of water heater backflow water saving fixtures, it comprises storage tank, storage tank water inlet pipe, storage tank outlet pipe and pneumatic transmission system, and storage tank water inlet pipe one end is connected with the hot-water line of water heater, and the other end is connected with storage tank; Storage tank outlet pipe one end is connected with the mixed water valve of water heater, and the other end is connected with storage tank; The pneumatic gearing system is connected with storage tank, also is provided with gas bleeder valve on the storage tank.
Further, said pneumatic actuator system comprises air pipe, pumping cylinder, piston, piston thrust device, air inlet pipe and air intake control valve, and air pipe one end communicates with pumping cylinder, and the other end is connected with storage tank; Air inlet pipe one end and atmosphere, the other end is connected with pumping cylinder, and air inlet pipe is provided with air intake control valve; Be provided with piston in the pumping cylinder, top land links to each other with the piston thrust device.
Said piston thrust device comprises connecting rod and handle, and connecting rod one end is connected with piston, and the hole slot that the other end is offered through the pumping cylinder top extends pumping cylinder, and is connected with handle.
Said air pipe is provided with the control valve of calming the anger.
Owing to adopted such scheme, the present invention to have following characteristics: when the invention solves each use water heater, the cold water in the needs water heater pipeline of etc.ing has flowed just has the hot water outflow afterwards, and the problem that this part cold water is wasted usually; And need not destroy original shower utensil.Apparatus of the present invention cost is lower, can produce in batches; Of many uses, can be used for hotel, communal facility and general family, be easy to promote; Energy dissipation is little, meets instantly the requirement of " energy-saving and emission-reduction ".
Description of drawings
Fig. 1 is the structural representation of backflow water saving fixtures of the present invention.
The specific embodiment
Below in conjunction with the accompanying drawing illustrated embodiment the present invention is further described.
As shown in Figure 1, water heater backflow water saving fixtures of the present invention are to realize through having increased storage tank and inlet and outlet pipe lines and pneumatic actuator system thereof on the basis of mixing the water valve system in original shower.The mixed water valve 1 of water heater is connected with hot-water line 2 and cold water pipe 3 respectively.Water heater backflow water saving fixtures of the present invention comprise storage tank 6, storage tank water inlet pipe 4, storage tank outlet pipe 7 and pneumatic actuator system, and storage tank water inlet pipe 4 one ends are connected with hot-water line 2, and the other end is connected with storage tank 6; Storage tank outlet pipe 7 one ends are connected with mixed water valve 1, and the other end is connected with storage tank 6.Storage tank water inlet pipe 4 is provided with water inlet control valve 5, and storage tank outlet pipe 7 is provided with water outlet one-way control valve 8.Pneumatic actuator system is located at storage tank 6 tops, and is connected with storage tank 6, for storage tank provides water pressure, also is provided with gas bleeder valve 17 on the storage tank 6.Device of the present invention can be installed in the body of wall that mixes water valve 1 top, and the volume size of storage tank 6 can be according to the on-demand customization of pipeline situation.After cold water got into storage tank 6, its energy used pneumatic actuator system to increase the energy of water in the storage tank less than the energy of water in the pipeline, and the water that is stored in the storage tank 6 is back in the mixed water valve 1.
