[Specific implementation method]

[0020] See also Figure 1 , Figure 2 and Figure 3 The present invention discloses a residential instant hot water system, comprising a pipeline 1, a temperature control valve 2 and an auxiliary heater 5. The pipeline 1 comprises a first branch pipe 11, a second branch pipe 12 and a main pipe 13. One end of the main pipe 13 is connected to the water outlet of the water heater and the other end is connected to one end of the first branch pipe 11 and the second branch pipe 12 through a three-way valve. The other ends of the first branch pipe 11 and the second branch pipe 12 are respectively connected to the water inlet of the hot water use end. The temperature control valve 2 and the auxiliary heater 5 are respectively installed on the main pipe 13 and the second branch pipe 12.

[0021] The first branch pipe 11 and the second branch pipe 12 are respectively installed with a check valve 3 , and the check valve 3 on the second branch pipe 12 is arranged between the three-way joint and the auxiliary heater 5 .

[0022] The first branch pipe 11, the second branch pipe 12 and the main pipe 13 are respectively installed with stop valves 4. The stop valves 4 on the first branch pipe 11 and the second branch pipe 12 are respectively arranged on the left and right sides of the check valve 3, and the stop valve 4 on the main pipe 13 is arranged between the water heater and the temperature control valve 2.

[0023] The second branch pipe 12 is provided with a temperature control valve 2 , and the temperature control valve 2 is arranged between the auxiliary heater 5 and the hot water use end.

[0024] The auxiliary heater 5 includes a support seat 51, a water pressure switch 52, a heating tube 53 and a controller 54. The water pressure switch 52 and the heating tube 53 are respectively fixed on the left and right sides of the support seat 51. The controller 54 is fixed in the support seat 51 and is electrically connected to the water pressure switch 52 and the heating tube 53 respectively.

[0025] The heating tube 53 includes a heating unit and a fuse unit, and the heating unit and the fuse unit are connected in series.

[0026] The support base 51 is further provided with a leakage protection switch 55 , and the leakage protection switch 55 is electrically connected to the controller 54 .

[0027] The auxiliary heater 5 also includes an inner sleeve 56 and an outer sleeve 57. The outer sleeve 57 is concentrically fixed inside the second branch pipe 12. The left end of the inner hole of the outer sleeve 57 is provided with a shrinking sleeve 571 whose inner diameter gradually decreases from left to right. The inner wall of the right section of the inner hole of the outer sleeve 57 is provided with an internal thread. The inner sleeve 56 is threadedly fixed inside the outer sleeve 57, and the support seat 51 is fixed on the inner wall of the inner sleeve 56.

[0028] The auxiliary heater 5 further includes handles 58 . One end of a plurality of the handles 58 is connected to the support base 51 or the inner casing 56 , while the free end thereof extends out of the inner casing 56 .

[0029] A plurality of handles 58 are disposed around the axis of the inner sleeve 56 .

[0030] Working process of the present invention:

[0031] During operation, taking the setting of the water temperature to 60°C as an example, when the temperature control valve 2 located on the main pipe 13 detects that the water temperature in the pipe reaches 60°C, the three-way valve opens the channel of the first branch pipe 11 and closes the channel of the second branch pipe 12, so that the hot water flows out directly along the first branch pipe 11; when the temperature control valve 2 located on the main pipe 13 detects that the water temperature in the pipe does not reach 60°C, the three-way valve closes the channel of the first branch pipe 11 and opens the channel of the second branch pipe 12, so that the hot water first flows from the main pipe 13 to the second branch pipe 12, and then flows out from the second branch pipe 12 after being quickly heated by the auxiliary heater 5.

[0032] When the auxiliary heater 5 is working, the water flows through the shrink sleeve 571 and triggers the water pressure switch 52, so that the heating tube 53 is energized and heats the water flowing through. During this period, if a dry burning problem occurs, the built-in fuse unit in the heating tube 53 will directly melt and cut off the power supply after reaching the preset temperature. If a leakage problem occurs, the leakage protection switch 55 will immediately cut off the power supply to prevent fire. In addition, before working, the handle 58 can be held and rotated, so that the inner sleeve 56 and the components installed thereon can rotate along the outer sleeve 57, so that the water pressure switch 52 is close to or away from the outlet of the shrink sleeve 571, so as to adjust the sensitivity of the water pressure switch 52 as needed.

[0033] The present invention connects the first branch pipe, the second branch pipe and the main pipe respectively through a three-way valve, thereby leading out a bypass line on the original hot water pipeline, and utilizing the cooperation of the temperature control valve, the three-way valve and the auxiliary heater, so that when the water temperature reaches the expected value, the hot water is directly discharged, and when the water temperature does not reach the expected value, the cold water is discharged after secondary heating, which can effectively utilize the original cold water in the water pipe, save water, and greatly improve the user experience; by adding a fuse unit and a leakage protection switch in the auxiliary heater, the occurrence of dry burning and leakage is effectively prevented, and the safety of use is improved; by threading the inner sleeve body in the outer sleeve body and arranging a shrinking sleeve in the outer sleeve body, the distance between the water pressure switch and the outlet of the shrinking sleeve can be adjusted as required, thereby adjusting the triggering sensitivity of the water pressure switch.

[0034] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention belongs to the protection scope of the present invention.
