Problems solved by technology

[0005] In the above two patents, whether setting a regulating valve to adjust the opening of the first water outlet (ie, the cold water outlet), or blocking the water inlet joint (ie, the hot water pipe) and the water outlet joint (ie, the cold water pipe) through the movable end of the one-way valve, Neither can fully guarantee that the one-way valve will not open when cold water is used, causing the water heater to start by mistake, but it can reduce the probability of the one-way valve opening to a certain extent.

Embodiment 1

[0053] Such as Figure 1~7 As shown, the gas water heater water supply system of this preferred embodiment includes a waterway structure, a water heater 5, a cold water pipe 6, a hot water pipe 7, and at least one water point 8 connecting the cold water pipe 6 and the hot water pipe 7 at the same time. The water heater 5 is connected to the farthest water point 8 (ie, water tap), and the waterway structure includes a pipe body 1, a one-way valve assembly 2, and the like.

[0054] The inside of the pipe body 1 is divided into a hot water pipe 11, a cold water pipe 12, and an intermediate pipe 13 connecting the hot water pipe 11 and the cold water pipe 12. The hot water pipe 11 has a hot water inlet 111 and a hot water outlet 112 that are in fluid communication. The pipe 12 has a cold water inlet 121 and a cold water outlet 122 that are in fluid communication, and the axis of the cold water outlet 122 is parallel or coincident with the axis of the intermediate pipe 13. In this embo...

Embodiment 2

[0067] Such as Figure 8~12 As shown, the difference between Embodiment 2 and Embodiment 1 is:

[0068] 1. Such as Figure 8~10 As shown, the slot 221 of the connecting rod 22 is provided with a limiting member 222 capable of colliding with the second end of the screw 4, and when the second end of the screw 4 collides with the limiting member 222, the screw 4 can no longer be screwed in In the slot 221, it is ensured that the screw 4 can subsequently rotate in the opposite direction relative to the connecting rod 22. Otherwise, if the screw 4 is screwed into the slot 221 too deeply, the screw 4 and the connecting rod 22 will be locked. In this embodiment, the limiting member 222 is a spring, one end of the spring is connected with the bottom wall of the slot 221, and the other end faces the screw 4; the connecting rod 22 is provided with a first drain hole 226 in fluid communication with the slot 221, This prevents water from entering the slot 221 and affecting the movement of th...

Embodiment 3

[0080] Such as Figure 13~16 As shown, the difference between Embodiment 3 and Embodiment 2 is that the connecting rod 22 is designed in a separate body.

[0081] In this embodiment, the connecting rod 22 includes two connecting rods. One connecting rod is connected to the plug 21, and the other connecting rod is provided with a slot 221. For ease of description, the connecting rod connected to the plug 21 is The first connecting rod 223a, the connecting rod threadedly connected with the screw 4 is the second connecting rod 223b, the first connecting rod 223a and the second connecting rod 223b are insert-fitted and movable relative to the axial direction, the end of the first connecting rod 223a An insertion hole 224 is provided. The end of the second connecting rod 223b is provided with an insertion portion 225 that can be inserted into the insertion hole 224. The insertion portion 225 can move axially along the insertion hole 224, and the opening of the insertion hole 224 exten...

Abstract

The invention relates to a water channel structure and a gas water heater water supply system with the water channel structure. The water channel structure comprises a pipeline body, a check valve assembly and a drive assembly, wherein the inner portion of the pipeline body is divided into a hot water pipeline, a cold water pipeline and an intermediate pipeline communicating with the hot water pipeline and the cold water pipeline, the hot water pipeline is provided with a hot water inlet and a hot water outlet which communicate with fluid, the cold water pipeline is provided with a cold waterinlet and a cold water outlet which communicate with the fluid, the check valve assembly comprises a plug which is movably arranged in the intermediate pipeline and can only allow water in the hot water channel to flow into the cold water pipeline in one direction, the drive assembly is arranged in the cold water pipeline and connected with the plug, in the state that the cold water outlet is opened, the drive assembly drives the plug to block the hot water pipeline and the cold water pipeline, so that it is avoided that the water heater is started by accident.

Description

Technical field [0001] The invention belongs to the technical field of gas water heaters, and particularly relates to a waterway structure and a gas water heater water supply system using the structure. Background technique [0002] With the improvement of living standards, zero-cold water gas water heaters are becoming more and more popular. To realize the instant heating function of zero-cold water gas water heaters, the water in the pipeline needs to be preheated, and the water pipe and the water heater need to form a closed circulation loop. . There are currently two schemes to realize the circulation loop: one is to install a return pipe; the other is to install a four-way one-way valve at the farthest water point of the water heater from the user's home to connect the cold water path of the tap water and the outlet water path of the water heater into a closed pipe Through the water heater's built-in circulating water pump, the water in the closed pipeline is preheated, and...
