In the embodiment of the present application, as shown in FIG. 10 , the waterway connector 90 includes a connector body 100 and a water trap 200 , and the connector body 100 is formed with a first cold water inlet 110 , a first hot water connection port 111 and a second hot water connection port 111 . A water intake port 112 for a faucet. The first cold water inlet 110 of the water trap 200 communicates with the second end of the corresponding outlet pipe, the first cold water inlet 110 and the first faucet water intake 112 respectively communicate with the first end of the water trap 200, and the first end of the water trap 200 The two ends communicate with the first hot water connection port 111 .

By setting the water trap 200 on the connector body 100, it is possible to prevent hot and cold water from cross-warming, reduce energy consumption, and improve user experience; There is no need to use pipelines such as silicone tubes, stainless steel tubes, or PP tubes, and fasteners such as tightening bands or fixing cards, which simplifies the pipeline structure and enables rapid installation.

In the embodiment of the present application, a first flow channel 113 and a second flow channel 114 are formed inside the connector body 100, the first flow channel 113 is a straight flow channel, the first cold water inlet 110 and the first faucet water intake 112 are at the second One direction is on the same straight line, the first end of the first flow channel 113 communicates with the first cold water inlet 110, and the second end of the first flow channel 113 communicates with the first end 212 of the trap and the water intake 112 of the first faucet respectively . The second flow channel 114 is an L-shaped flow channel, the first end of the second flow channel 114 communicates with the second end 213 of the trap, the second end of the second flow channel 114 communicates with the first hot water connection port 111, The first cold water inlet 110 , the first hot water connection port 111 and the first faucet water intake 112 are all provided with seals.

It should be noted here that the first direction refers to the front-back direction in FIG. 11 . Of course, the arrangement of the connection ports is not limited thereto, and is specifically determined according to the positional relationship between the cold water container and the faucet. The types of seals of each connection port can be the same or different, and the type of seals is specifically determined according to the inner wall thickness and inner wall structure of each connection port.

In the related art, the cold water container, the hot water container, and the container containing normal temperature water are connected to each other, requiring a large number of pipeline parts such as silicone tubes, stainless steel tubes, and PP tubes, and fasteners such as fixing clips and tightening bands. However, the waterway connector 90 of this embodiment avoids the use of pipeline components such as silicone tubes, stainless steel tubes or PP tubes, and fasteners such as fixing cards or tightening bands by providing flow channels on the connector body 100 . Since it is only necessary to connect the corresponding connection port with the corresponding container, there is no need to connect through pipeline parts, which simplifies the installation steps, enables quick installation, and enhances the user experience.

In the embodiment of the present application, the first flow channel 113 and the second flow channel 114 protrude from the first side of the connector body 100, of course, the first flow channel 113 and the second flow channel 114 can also protrude from the connector the second side of the body 100 . By making the first channel 113 and the second channel 114 protrude from the surface of the connector body 100 , the thickness of the connector body 100 is reduced and the weight of the connector body 100 is reduced.

It should be noted here that the first side of the connector body 100 refers to the upper surface of the connector body 100 in FIG. 11 , and the second side of the connector body 100 refers to the lower surface of the connector body 100 in FIG. 11 .

Since the water trap 200 is arranged up and down, when the hot water enters the third flow channel through the second end of the second diversion section 211, according to the principle of heat conduction, the hot water in the third flow channel is at the top and the cold water is at the bottom, which can effectively reduce the Heat conduction and convection between cold and hot water to solve the problem of cross temperature between cold and hot water.

The capacity of the third channel should be greater than the product of the volume of the hot water container and the expansion coefficient of water heating. Assume that the capacity of the third channel is Q1, the volume of the hot water container is Q2, and the expansion coefficient of water heating is K. (According to physical phenomena, when the water is heated above 90 degrees, the hot water expansion coefficient is about 5-10%), so the capacity of the third channel Q1≥Q2*K, of course, in the case of space design, the larger the Q1, the better Well, the preferred item is Q1≥2*Q2*K.

The preferred option is a vertically arranged U-shaped flow channel. The capacity of water in the hot water container is 1L, the capacity of water in the third channel is 80ml, the water temperature in the hot water container is 95°, and the water inlet temperature is 25°, as shown in Figure 14, since there is no water trap 200 in the pipeline, That is, the third flow channel does not exist, and the water inlet pipe is in a horizontal state at this time. Since there is no anti-cross-temperature structure, the anti-cross-temperature effect is poor, and the water inlet temperature is 53° after testing. As shown in FIG. 15 , when the third channel can be V-shaped, the angle between the first end of the second guide section 211 and the vertical direction is 45°, and the detected inlet water temperature is 35°. As shown in FIG. 16 , when the third flow channel can be U-shaped, the first end of the second diversion section 211 is in a vertical state, and the detected inlet water temperature is 26°.
