Description
Technical Field
The invention relates to a water heater accessory, in particular to a hot water guide pipe.
Background
The water heater is a common household appliance, a main machine of the water heater is usually arranged at a kitchen position and is distributed to other rooms through a warm pipe and a cold pipe, so that hot water in each room can be used; because the pipeline arranged in the heating pipe is long, hot water is not used for a period of time, and the hot water remained in the heating pipe is naturally cooled; when hot water is needed, a user can reuse the hot water only when the hot water cooled by the heating pipe is discharged, the waiting time in the process is long, and cold water discharged by the heating pipe cannot be recycled basically, so that certain water resource waste is caused; there is currently no suitable method to save these valuable water resources.
Disclosure of Invention
Aiming at the problems, the invention provides the water-saving guide pipe of the water heater, which has the advantages of novel structure and unique principle, can effectively shorten the waiting time of hot water, and simultaneously reduces the waste of water resources.
In order to solve the problems, the technical scheme adopted by the invention is as follows: the water-saving guide pipe of the water heater comprises an outer pipe, wherein the outer pipe is connected with a hot water port of the water heater;
the inner pipe is arranged on the axis of the outer pipe, the inner pipe and the outer pipe are connected and fixed through fixing plates, and the fixing plates are distributed around the inner pipe in a rotational symmetry manner; an elastic water-stop film is arranged between the adjacent fixing pieces, the water-stop film, the fixing pieces and the inner pipe are combined into a water-stop cylinder capable of being shrunk and expanded, and the water-stop film is always kept in a tight state; sealing films are arranged at two ends of the water-resisting cylinder, and the sealing films seal the water-resisting cylinder into an airtight cavity;
the airtight cavity is connected with an air guide pipe, and the pipe end of the air guide pipe extends out of the outer pipe;
the inner surface of each water-stop film is fixedly provided with a shaping strip parallel to the axis of the inner pipe, the axis of the inner pipe is provided with a driving strip capable of moving relative to the inner pipe, and two ends of the driving strip and the inner pipe keep liquid seal sliding; the shaping strip and the driving strip are connected through a traction wire penetrating through the wall of the inner pipe, and the traction wire can freely slide relative to the inner pipe;
one end part of the driving strip close to the hot water port extends out of the sealing film, and a pressure bearing plate is arranged at the end part of the driving strip.
The invention has the beneficial effects that: the water-resisting film is always kept in a tight state, when the hot water pipe is not filled with water, the water-resisting film on the surface of the water-resisting cylinder is tight, and the water-resisting cylinder is in an expansion state; the gap between the water-resisting film and the outer pipe is smaller, so that the residual hot water in the pipe is less;
when hot water is needed, the hot water flows out from a hot water port of the water heater at a certain water pressure; hot water impacts the bearing plate and flows through a gap between the water-resisting film and the outer pipe at the same time; when water pressure impacts the pressure bearing plate, the driving strip is pushed to slide relative to the inner pipe, so that the driving strip drives the traction wire to slide, and further the shaping strip is pulled; the shaping strip is close to the inner pipe to enable the water-stop film to be sunken towards the position of the inner pipe, the water-stop cylinder is shrunk at the moment, the gap between the water-stop film and the outer pipe is enlarged, and more hot water can flow through the gap; in the initial stage of the process, hot water flows through the narrow gap to extrude out cold water remained in the gap; then, hot water can flow through the rapidly enlarged gap for normal use of a user; because the original gap is smaller and the residual cold water is less, the waste of cold water resources is less when in use; meanwhile, the water pressure of the water outlet of the water heater is fixed, when the gap between the water-stop film and the outer pipe is small, the flow rate of hot water in the water-stop film is increased, the hot water can rapidly pass through the gap, and therefore the waiting time of a user is obviously shortened.
After the use of the user is finished, the water pressure of the hot water port is reduced; the water-stop film is restored to the original state under the action of the elastic force of the water-stop film, and then the water-stop cylinder is restored to the expansion state again; at the moment, the gap between the water-stop film and the outer pipe is reduced, redundant hot water in the pipe is extruded back into the water heater, and the pipeline returns to the water-saving state.
In conclusion, when the water heater is used, a user does not need to replace or disassemble the existing water heater, and only needs to reconnect the hot water pipe, so that the replacement cost is effectively reduced; after the water-saving conduit is used, the waiting time of a user can be effectively shortened, and meanwhile, the waste cold water resources can be obviously reduced; has obvious advantages in use and environmental protection.
Preferably, the fixing piece extends in a radial direction of the outer tube; the structure can reduce the production difficulty and increase the volume of the water-resisting cylinder, thereby further reducing the waste of cold water resources.
Preferably, the fixing pieces which are rotationally and symmetrically distributed around the inner pipe form a group of water saving units, and the water saving units of each group are distributed at equal intervals along the inner pipe; the structure can form a plurality of groups of water-saving units and is convenient for bending the water-saving guide pipe.
