[0031] Reference below Figures 1 to 5 A four-chamber water mixing tank according to an embodiment of the first aspect of the present invention is described.

[0032] According to the four-chamber water mixing tank of the first embodiment of the present invention, it includes a water mixing tank body, a water inlet pipe 220 is provided on the upper side of the water mixing tank body, and a water discharge pipe 320 is provided on the lower side of the water mixing tank body; the water mixing tank body has an inner cavity, the inner cavity includes an upper cavity part and a lower cavity part, a partition 500 is provided between the upper cavity part and the lower cavity part, the upper cavity part includes a left upper cavity part 410 and a right upper cavity part 420, the water inlet pipe 220 is provided between the left upper cavity part 410 and the right upper cavity part 420, and the lower cavity part It includes a lower left cavity portion 430 and a lower right cavity portion 440, and the drain pipe 320 is arranged between the lower left cavity portion 430 and the lower right cavity portion 440; a plurality of connecting holes 530 are provided on the partition 500, at least one connecting hole 530 is provided between the upper left cavity portion 410 and the lower left cavity portion 430, and at least one connecting hole 530 is provided between the upper right cavity portion 420 and the lower right cavity portion 440, and the partition 500 has a solid portion, which is arranged between the bottom of the water inlet pipe 220 and the top of the drain pipe 320.

[0033] For example, Figures 1 to 3As shown, the main body of the mixing tank can be composed of an upper cover plate 110, a tank body 120, and a lower cover plate 130. The upper cover plate 110 is arranged on the top of the tank body 120, and the lower cover plate 130 is arranged on the bottom of the tank body 120. The water inlet pipe 220 is arranged on the upper cover plate 110, and the drain pipe 320 is arranged on the lower cover plate 130; a partition plate 500 is arranged in the tank body 120, and the partition plate 500 divides the space in the tank body 120 into an upper cavity and a lower cavity. The lower end of the water inlet pipe 220 extends downward to a position close to the partition plate 500, and the upper end of the drain pipe 320 extends upward to a position close to the partition plate 500. The partition plate 500 can be installed in the upper middle position, the middle, or the lower middle position in the tank body 120, and can be adjusted according to actual needs; the water inlet pipe 220 and the drain pipe 320 can be arranged on the same straight line. In addition, as shown in FIG. Figure 5 As shown, the water inlet pipe 220 and the drain pipe 320 can also be staggered; furthermore, as Figure 6 As shown, the main body of the water mixing tank can be flat to adapt to water heaters with relatively narrow internal installation space.

[0034] In this way, after the water flows into the tank body 120 from the water inlet pipe 220, it sprays on the solid part of the partition 500, and then flows back obliquely upward into the upper left cavity 410 and the upper right cavity 420. The water flows in the upper left cavity 410 and the upper right cavity 420 and mixes with the water originally in the tank body 120. Part of the water flows through the connecting hole 530 and enters the lower left cavity 430 and the lower right cavity 440. In the lower left cavity 430 and the lower right cavity 440, the water flows and mixes with the water originally in the tank body 120. Part of the water flows through the drain pipe 320 and is discharged to the outside of the tank body 120. Figure 4 shown.

[0035] When in use, the four-chamber mixing tank can be placed on the water outlet pipe of the water heater. The water heated by the heat exchanger of the water heater flows into the inner cavity from the water inlet pipe 220, mixes with the water in the inner cavity, and then flows out from the drain pipe 320, reducing the fluctuation range of the water outlet temperature of the water heater.

[0036] To facilitate installation, in some embodiments of the present invention, a water inlet connector 210 is provided at the top of the water inlet pipe 220, which is located outside the main body of the water mixing tank. A drain connector 310 is provided at the bottom of the drain pipe 320, which is located outside the main body of the water mixing tank. The connection between the connector and the external water pipe can be a snap-fit ​​connection, a threaded connection, or other sealed connection method.

[0037] In some embodiments of the present invention, a first, inwardly recessed ridge 121 is provided on the front side of the mixing tank body, and the first ridge 121 is arranged vertically. A second, inwardly recessed ridge is provided on the rear side of the mixing tank body, and the second ridge is arranged vertically. The first ridge 121 and the second ridge can make the tank body 120 more structurally stable and improve the pressure resistance of the tank body 120. In addition, the water inlet pipe 220 and the drain pipe 320 can be arranged between the first ridge 121 and the second ridge. In this way, the first ridge 121 and the second ridge can separate the upper left cavity 410 from the upper right cavity 420, and also separate the lower left cavity 430 from the lower right cavity 440, which facilitates the circulation of water within each cavity and improves the mixing effect.

[0038] In some embodiments of the present invention, the upper left chamber 410, the upper right chamber 420, the lower left chamber 430, and the lower right chamber 440 are all cylindrical, which can effectively utilize the space in the tank, reduce the "dead zone" of the water flow, and further improve the mixing effect.

[0039] In some embodiments of the present invention, the partition 500 is provided with a downwardly recessed groove 510, which is provided on the solid portion and below the water inlet pipe 220. Thus, after water flows from the water inlet pipe 220 into the tank body 120, it sprays onto the groove 510 of the partition 500 and, guided by the groove 510, flows obliquely upward into the upper left and upper right chambers 410, 420. Within the upper left and upper right chambers 410, 420, the water circulates due to the restriction of the tank body 120, resulting in effective mixing of the water.

[0040] In some embodiments of the present invention, the upper left cavity 410 and the upper right cavity 420 are bilaterally symmetrical, and the lower left cavity 430 and the lower right cavity 440 are bilaterally symmetrical. The water inlet pipe 220 and the drain pipe 320 can be located in the center of the water mixing tank body. After entering the tank body 120 through the water inlet pipe 220, the water can flow evenly to the left and right, fully utilizing the space within the tank body 120 for mixing.

[0041] In some embodiments of the present invention, the communication hole 530 disposed between the upper left cavity 410 and the lower left cavity 430 is referred to as the left communication hole 530, and is disposed on the left edge of the partition 500. The communication hole 530 disposed between the upper right cavity 420 and the lower right cavity 440 is referred to as the right communication hole, and is disposed on the right edge of the partition 500. In this manner, water flows downward from the communication hole 530 into the lower left cavity 430 and the lower right cavity 440, and then flows back upward through the action of the tank body 120, with part of the water flowing out of the drain pipe 320 and part of the water flowing back to the bottom of the communication hole 530, where it then circulates, resulting in more complete mixing of the water.

[0042] In some embodiments of the present invention, a protrusion 520 is provided on the bottom of the partition 500. The protrusion 520 is provided on the solid portion and above the drain pipe 320. The protrusion 520 prevents the water in the lower left cavity 430 and the lower right cavity 440 from flowing toward the drain pipe 320, thereby enhancing the circulation of the water in the lower left cavity 430 and the lower right cavity 440 and providing more complete mixing of the water.

[0043] In some embodiments of the present invention, three left communication holes are provided between the upper left chamber 410 and the lower left chamber 430, and are evenly distributed along the left edge of the partition 500. Three right communication holes are provided between the upper right chamber 420 and the lower right chamber 440, and are evenly distributed along the right edge of the partition 500. This allows the water flow from the upper chamber to the lower chamber to be close to the inner wall of the tank body 120, which facilitates mixing of the water flow.

[0044] The water heater according to the second embodiment of the present invention comprises the four-chamber water mixing tank according to the first embodiment of the present invention, and the four-chamber water mixing tank is arranged on the water outlet pipe of the water heater.

[0045] According to the water heater of the embodiment of the present invention, by arranging the above-mentioned four-chamber water mixing tank on the water outlet pipe of the water heater, the fluctuation range of the water outlet temperature of the water heater is reduced.

[0046] The above specifically describes the preferred embodiments of the present invention, but the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
