The first end of the water inlet pipe 330 communicates with the accommodating chamber 301, and the second end of the water inlet pipe 330 communicates with the first hot water connection port. .

According to the water storage device of the embodiment of the present application, by setting the one-way valve 220 between the first cold water inlet 110 and the first hot water connection port, it is possible to prevent the hot water in the container body from cross-talking with the cold water in other containers. , reduce the energy consumption of the water storage device, and improve the user experience; by setting the connection ports for connecting with the hot water container and the cold water container on the connector body 100, there is no need to use silicone tubes, stainless steel tubes, or PP tubes and other pipelines and bundles. Fasteners such as tight straps or fixed clips simplify the pipeline structure and enable quick installation.

It should be noted here that the container 300 is arranged below the connector body 100, and the container 300 is a hot water container. Of course, the container can also be a cold water container. The water inlet port 227 communicates with the first hot water connection port, and the water outlet port 228 of the one-way valve 220 communicates with the first cold water inlet 110 .

In the embodiment of the present application, the connector body 100 is further formed with a first faucet water intake 112, the first faucet water intake 112 and the first cold water inlet 110 are located on the first side of the connector body 100, the first hot water connection The port is located on the second side of the connector body 100 .

In the embodiment of the present application, Fig. 3 illustrates a schematic cross-sectional structural view of the water storage device provided in the embodiment of the present application, and Fig. 4 illustrates a schematic side view of the water storage device provided in the embodiment of the present application, as shown in Fig. 3 and Fig. 4, the one-way valve 220 includes a valve body 221 and a valve core 223, the inside of the valve body 221 is formed with a valve body flow channel, and the two ends of the valve body flow channel respectively form a water inlet 227 and a water outlet 228, that is, the valve body The lower end of the flow channel forms a water inlet 227 , and the upper end of the flow channel of the valve body forms a water outlet 228 . A first sealing surface 222 is formed on the inner wall of the flow channel of the valve body, and the first sealing surface 222 is horizontally arranged and located below the valve core 223 . The valve core 223 is arranged in the flow channel of the valve body. The valve core 223 is made of silica gel. The bottom of the valve core 223 is formed with a second sealing surface 224. The valve core 223 is suitable for switching between a closed position and an open position; in the closed position, The first sealing surface 222 is bonded to the second sealing surface 224 to block the flow channel of the valve body. In the open position, the second sealing surface 224 is separated from the first sealing surface 222 and the flow channel of the valve body is connected.

Fig. 6 illustrates the third schematic diagram of the side view sectional structure of the one-way valve provided by the embodiment of the present application. As shown in Fig. Under the action of gravity, the cold water enters into the flow channel of the valve body through the cold water container and the first cold water inlet 110 in sequence. At this time, the pressure of the cold water is greater than the pressure of the hot water, and the water flows upward in the flow channel of the valve body, and the water pushes the valve core 223 to overcome itself. Gravity moves from the closed position to the open position. Since there is no sealing surface above the valve core 223, cold water continuously flows into the first hot water connection port through the valve body flow channel, and finally enters the hot water container.

Figure 5 illustrates the second schematic diagram of the side view sectional structure of the one-way valve provided by the embodiment of the present application. The water flows downward, and the water presses down on the valve core 223, so that the second sealing surface 224 at the bottom of the valve core 223 is attached to the first sealing surface 222, and the valve core 223 blocks the flow channel of the valve body. Moreover, the greater the pressure exerted by the water on the valve core 223, the tighter the second sealing surface 224 and the first sealing surface 222 adhere, and the better the sealing performance is. Since the valve core 223 blocks the flow channel of the valve body, hot water cannot enter the cold water container through the flow channel of the valve body, thereby preventing temperature crossover between hot and cold water, reducing energy consumption, and improving user experience.

It should be noted here that the material of the valve body 221 is not limited to silica gel, and may also be rubber or other flexible materials.

In the embodiment of the present application, the spool 223 is cylindrical, the cross section of the valve body flow channel is circular, and there is a certain gap between the spool 223 and the inner wall of the valve body flow channel to ensure that the spool 223 is in the valve The fluid channels are free to move.

In the embodiment of the present application, the first sealing surface 222 is an annular plane, and the first sealing surface 222 is arranged horizontally; the second sealing surface 224 is a circular plane, and the second sealing surface 224 is arranged horizontally; The diameter is greater than the diameter of the second sealing surface 224 . By making the outer diameter of the first sealing surface 222 larger than the diameter of the second sealing surface 224, in the closed position, even if a certain amount of displacement occurs in the position of the valve core 223, there is no gap between the first sealing surface 222 and the second sealing surface 224. Leakage will occur, which reduces the processing accuracy requirements of the valve core 223 and the valve body 221 and reduces the production cost.

In one embodiment of the present application, Fig. 7 illustrates the third schematic diagram of the side view sectional structure of the one-way valve provided by the embodiment of the present application. As shown in Fig. 7, the second sealing surface 224 is a conical surface, and the first sealing surface 222 is an inclined annular surface. By setting the second sealing surface 224 as a conical surface, when the valve core 223 is subjected to a downward pressure, the tighter the second sealing surface 224 and the first sealing surface 222 fit, the tighter the sealing performance will be. the better.

In the embodiment of the present application, a concave portion 225 is provided on the side of the valve core 223 away from the first sealing surface 222, and the setting of the concave portion 225 can make the inside of the valve core 223 hollow, reduce the weight of the valve core 223, and increase the buoyancy of the valve core 223 . The upwardly moving water only needs to apply a small thrust to the valve core 223 to push the valve core 223 away from the closed position.

In the embodiment of the present application, the inner wall of the flow channel of the valve body is provided with a plurality of limiting parts 226 at intervals, and the limiting parts 226 are located on the side of the valve core 223 away from the first sealing surface 222, that is, the limiting parts 226 are located on the side of the valve core. 223 above. In the open position, the side of the valve core 223 away from the first sealing surface 222 abuts against the limiting portion 226 . Since there is a gap between two adjacent limiting parts 226, water can flow through the gap, and the valve core 223 cannot block the flow channel of the valve body.

It should be noted here that the number of limiting portions 226 may be two, or three or more, and the distance between two adjacent limiting portions 226 may be equal or unequal.

In the embodiment of the present application, as shown in FIG. 1 , FIG. 3 and FIG. 4 , the waterway connector 90 further includes a water trap 200 , and a first diversion section 210 and a second diversion section are formed inside the trap 200 211, the first end of the first diversion section 210 communicates with the first cold water inlet 110, the second end of the first diversion section 210 communicates with the water inlet 227, the first end of the second diversion section 211 communicates with the first The hot water connection port is connected, the second end of the second diversion section 211 is communicated with the water outlet 228 , and the first diversion section 210 , the second diversion section 211 and the flow channel of the valve body together form a U-shaped flow channel. Since the water trap 200 is arranged up and down, after the hot water enters the second diversion section 211, according to the principle of heat conduction, the hot water in the second diversion section 211 is on the top and the cold water is on the bottom, which can further reduce the heat conduction between hot and cold water. Convection, to solve the temperature problem between hot and cold water.

It should be noted here that the first end of the first diversion section 210 is the first end 212 of the trap, and the first end of the second diversion section 211 is the second end 213 of the trap.

The capacity of the water trap 200 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 anti-crossover effect is also related to the shape of the third flow channel. The third flow channel can be V-shaped, U-shaped or other shapes. 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 12, 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. 13 , 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. 14 , 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°. Therefore, when the third flow channel is U-shaped, the water trap 200 has the best effect of preventing cold and hot water from cross-warming.

In the embodiment of the present application, as shown in FIG. 4 , the second end of the first diversion section 210 is plugged and connected to the water inlet 227 , and the second end of the second diversion section 211 is plugged and connected to the water outlet 228 , the valve body 221 is connected to the water trap 200 by screws. In order to improve the sealing performance, the outer peripheral surface of the water inlet end 227 and the outer peripheral surface of the water outlet end 228 are both provided with sealing rings.

It should be noted here that the connection between the valve body 221 and the water trap 200 is not limited to the screw connection, and can also be connected by buckles, and the valve body 221 and the water trap 200 can also be integrally formed.

It should be noted here that when the connector body 100 is horizontally arranged above the hot water container, since the water trap 200 is vertically arranged on the side of the connector body 100 close to the water intake 112 of the first faucet, the water trap 200 does not It will affect the installation of the connector body 100 . Certainly, the installation position of the water trap 200 is not limited thereto, and may also be installed at other positions of the connector body 100 .

It should be noted here that the first direction refers to the front-back direction in FIG. 4 , of course, the arrangement of the connecting 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. 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.
