Description
Technical Field
The invention relates to a water heater accessory, in particular to a hot water 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
In view of the above problems, the present invention provides a water saving heating pipe, which can effectively reduce the residual water in the heating pipe when water is not used, thereby reducing the waste of water resources and shortening the waiting time for water use.
In order to solve the problems, the technical scheme adopted by the invention is as follows: the water-saving heating pipe comprises an outer pipe, wherein the outer pipe comprises a fixed layer, a heat-insulating layer and a protective layer; one end of the outer pipe is communicated with the water heater, and the other end of the outer pipe is communicated with the control valve;
an inner pipe is arranged on the axis of the outer pipe, one end of the inner pipe is communicated with the water heater, and the other end of the inner pipe is communicated with the control valve; the outer peripheral wall of the inner tube is rotationally and symmetrically provided with support sheets, the outer parts of the support sheets are wrapped with adjusting bags made of elastic materials, flexible sealing films are arranged at two ends of the adjusting bags, and the edges of the sealing films are hermetically connected with the adjusting bags and the inner tube to form a closed tube barrel space; the space of the pipe barrel is provided with an air duct, and the end part of the air duct extends out to the outside air;
the inner wall of the adjusting bag is provided with adjusting strips parallel to the supporting sheets, and each adjusting strip is arranged between two adjacent supporting sheets; induction strips made of thermal expansion materials are arranged in the inner pipe at equal intervals, and the induction strips expand and extend along the axis of the induction strips after being heated; one end of the induction strip is fixedly connected with the inner tube, and the other end of the induction strip is free and connected with the traction wire; the traction wire penetrates through the pipe wall of the inner pipe and then is connected with the adjusting strip; and a liquid seal is kept between the traction wire and the pipe wall of the inner pipe.
The invention has the beneficial effects that: the inner pipe and the outer pipe are both communicated with the water heater, and when hot water is used, the hot water flows through the inner pipe and the outer pipe simultaneously; when hot water flows through the inner pipe, the induction strip inside is heated, and the induction strip expands and extends along the axis direction of the induction strip after being heated, so that a traction wire at the end part is pulled, the traction wire synchronously pulls the adjusting strip towards the inner pipe, and the adjusting bag is elastically deformed and shriveled; meanwhile, hot water also flows in a gap between the outer pipe and the adjusting bag, and the water pressure further extrudes the adjusting bag to promote the deformation and the deflation of the adjusting bag; at this time, the gap between the outer pipe and the regulating bag is enlarged, and the flow surface through which hot water can pass is enlarged, so that sufficient hot water is supplied to the user.
When the user does not use hot water any more, the water heater does not continuously pressurize and spray water, and meanwhile, the hot water in the heating pipe is gradually cooled; the induction strip is gradually shortened along with the reduction of the temperature; the elastic bag recovers elastic deformation, and the adjusting strip gradually resets due to the fact that the traction wire loses traction force; along with disappearance of water pressure and pull wire pulling force, the elastic bag restores to the original shape gradually, and the space between elastic bag and the outer tube dwindles gradually, and the water between the space is poured back into the hydrophone, and the water that remains in the outer tube at this moment obviously diminishes.
When the user uses the hot water again, the hot water can be obtained only by discharging a small amount of cold water remained in the pipe body, so that the structure can effectively reduce the waste of water resources; meanwhile, because the water pressure of the water heater is fixed, and the gap between the elastic bag and the outer pipe is smaller when the elastic bag is restored to the original state, namely the circulation surface where hot water in the heating pipe can flow is smaller, at the moment, the hot water is sprayed in the outer pipe and the inner pipe at a high speed; therefore, the time for the user to wait for the hot water is shortened, thereby facilitating the user to quickly obtain the hot water.
In conclusion, the structure of the invention is exquisite, the water heater does not need to be modified and purchased again, and only the heating pipe needs to be replaced, so that the installation and the use are convenient and quick; this structure can effectively shorten the user and wait for hydrothermal time, reduces the waste of water resource simultaneously, consequently has higher spreading value.
Preferably, a filter valve is arranged in the gas guide pipe; so as to reduce the entry of dust into the adjustment capsule and thus cause the latter to age.
Preferably, the support sheet extends in a radial direction of the inner tube; so as to provide a larger deformation space for the regulating bag and further improve the hot water outlet speed and the water saving performance of the water-saving heating pipe.
