Embodiment 1

[0022] Such as Figure 1-3 As shown, a self-regulating water pipe for a domestic water heater includes a pipe body 1, an annular box 2 is installed outside the pipe body 1, the annular box 2 is coaxially sleeved outside the pipe body 1, and the inside of the pipe body 1 is provided with an elliptical section. The deformation capsule 3 is arranged in a shape, the two ends of the deformation capsule 3 are fixed with the inner side wall of the pipe body 1, the side walls on both sides of the deformation capsule 3 are in the shape of an outwardly protruding arc, and one end of the annular box 2 is connected with a Pipe 4, the other end of the connecting pipe 4 runs through the pipe body 1 and communicates with the annular box 2. There is an annular sealing plate 5 for sealing and sliding in the annular box 2. A plurality of memory springs 6 are installed on one side of the annular sealing plate 5, and a plurality of memory springs 6 are installed. The other end of spring 6 is all ...

Embodiment 2

[0028] Such as Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that: the upper end of the annular box 2 is provided with an exhaust hole 8 , and a whistle 9 is installed in the exhaust hole 8 .

[0029] In this embodiment, when the cold water in the pipe body 1 is exhausted, the temperature of the pipe body 1 rises, the deformation of the memory spring 6 drives the annular sealing plate 5 to move upward, and the air above the annular sealing plate 5 is discharged from the annular box through the exhaust hole 8 In addition, when the air flows in the whistle tube 9, a sound is made due to the turbulence of the air flow. At this time, the user can judge that the cold water has been drained after hearing the prompt sound, and there is no need to test the water temperature many times to avoid the problem of causing a cold.

Embodiment 3

[0031] Such as Figure 5-6 As shown, the difference between this embodiment and Embodiment 1 is that: the outer wall of the deformation capsule 3 is equidistantly arranged with scrapers 10, and the scrapers 10 are made of memory metal material.

[0032] In this embodiment, when the deformation capsule 3 is inflated, the end of the scraper far away from the deformation capsule 3 contacts the inner wall of the pipe body 1. When water is injected into the tube body 1, the scraper 10 is heated and deformed rapidly, and rubs against the inner wall of the tube body 1 to scrape off the scale accumulated on the inner wall of the tube body 1. It flows outside, and according to the user's water consumption needs, the water flow speed will be continuously adjusted. According to Bernoulli's distance, when the flow is at a constant height, the greater the flow rate, the lower the pressure, which will drive the deformation capsule 3 to be subject to changing pressure, that is, repeated occu...

Abstract

The invention belongs to the field of smart home, and particularly relates to a self-regulating water pipe for a household water heater. The water pipe comprises a pipe body, wherein an annular box isinstalled outside the pipe body in a coaxial sleeving manner; a deformation bag with an elliptical cross section is arranged in the pipe body, two ends of the deformation bag are fixed with the innerside wall of the pipe body, and the two side walls of the deformation bag are in an outward convex arc shape; one end of the annular box communicates with a communication pipe, and the other end of the communication pipe penetrates the pipe body and communicates with the annular box; an annular sealing plate is installed in the annular box in a sealed sliding manner; a plurality of memory springsare installed on one side of the annular sealing plate, and the other ends of the memory springs are fixed with the inner side wall of the annular box. The size of the deformation bag can be adjustedaccording to the water temperature in the pipe body, so that the amount of water in the pipe body is changed, waste of water resources is reduced, and time for users to wait for hot water is shortened.

Description

technical field [0001] The invention belongs to the field of smart home, and in particular relates to a self-regulating water pipe of a domestic water heater. Background technique [0002] With the development of society, people's awareness of energy saving and emission reduction is increasing. Household water heaters with less energy consumption will be a direction of future development. Among them, solar water heaters and air energy water heaters are developing better as low energy consumption products. [0003] When traditional water heaters are in daily use, due to the long pipeline layout of the hot water pipes, after a period of time without use, the residual hot water in the hot water pipelines will cool down naturally. Hot water will flow out after it is discharged, which not only needs a long time to wait, but also causes a waste of water resources, and in the process of discharging cold water, people need to constantly test whether the cold water has been discharge...
