[0030] In the following, only certain exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature rather than limiting.

[0031] As Figure 1 shown, as one aspect of the embodiments of the present application, the present embodiments provide a mixed water valve 100, comprising a mixed water cavity 1, a cold water cavity 2, a hot water cavity 6 and a valve 3.

[0032] The mixed water cavity 1 has a mixed water inlet 14, a mixed water outlet 12 and a first connecting end 13. The first connecting end 13 connects the mixed water inlet 14 and the mixed water outlet 12.

[0033] The hot water cavity 6 has a hot water inlet 11, which is communicated with the mixed water inlet 14. The hot water inlet 11 is used to deliver hot water into the mixed water cavity 1.

[0034] The cold water cavity 2 has a cold water inlet 21, a cold water outlet 22 and a second connecting end 23. The cold water inlet 21 is communicated with the cold water outlet 22 and the second connecting end 23.

[0035] The valve 3 is arranged between the cold water cavity 2 and the mixed water cavity 1. The water inlet end 31 of the valve 3 is communicated with the second connecting end 23, the water outlet end 32 of the valve 3 is communicated with the first connecting end 13, and the water outlet end 32 of the valve 3 corresponds to the position of the mixed water inlet 14. So that in the case that the valve 3 is in an open state, the cold water in the cold water cavity 2 can flow into the mixed water inlet 14 through the valve 3.

[0036] The water outlet end of the valve of the embodiments of the present application corresponds to and is communicated with the mixed water inlet through the first connecting end, and the mixed water inlet is communicated with the hot water inlet. Therefore, after the cold water of the cold water cavity enters the mixed water cavity through the valve, the cold water can be fully mixed with the hot water entering through the hot water inlet in the mixed water cavity, so that mixed water of appropriate temperature flows out from the mixed water outlet. The mixed water valve provided by the embodiments of the present application has simple structure, small volume and convenient installation.

[0037] In one example, the mixed water cavity 1, the cold water cavity 2 and the valve 3 are arranged on the same plane. Thus, the mixed water cavity 1, the cold water cavity 2 and the valve 3 communicate to form a "one" type structure, reducing the occupied space of the mixed water valve 100.

[0038] It should be noted that the water mixing cavity 1, the cold water cavity 2 and the valve 3 in the embodiment of the present application are arranged on the same plane, which can mean that the water mixing cavity 1, the cold water cavity 2 and the valve 3 are arranged on the same axis. In the case of horizontal placement, the valve 3 is opened, and water between the water mixing cavity 1 and the cold water cavity 2 can flow. The shapes and sizes of the water mixing cavity 1 and the cold water cavity 2 can be the same or different.

[0039] In one example, a valve sleeve 4 can also be included, the valve 3 is located in the valve sleeve 4, and the valve sleeve 4 is fixedly connected with the water mixing cavity 1 and the cold water cavity 2. In one example, the valve sleeve 4 can be integrally formed with the water mixing cavity 1 and the cold water cavity 2. It should be understood that the water mixing cavity 1, the cold water cavity 2 and the valve 3 can also be fixedly connected in other ways, which are not limited in the embodiment of the present application.

[0040] In the embodiment of the present application, when the valve 3 is opened, cold water enters the cold water cavity 2 from the cold water inlet 21, passes through the valve 3 to the water mixing cavity 1. At the same time, hot water enters the water mixing cavity 1 from the hot water inlet 11, mixes with the cold water entering the water mixing cavity 1, and then flows out from the water mixing outlet 12. When the valve 3 is closed, hot water enters the water mixing cavity 1 from the hot water inlet 11, and no cold water is mixed with it, so that hot water flows out from the water mixing outlet 12.

[0041] In the embodiment of the present application, the water mixing valve 100 can be applied to any water-using device used in people's daily life, for example, a water-using device in the gas field, a kitchen water-using device, a drinking water device, a medical cleaning device, etc. The water-using device can include a heat exchange device for heating cold water to generate hot water. The cold water outlet 22 can be connected to the water inlet pipe of the heat exchange device, and the hot water inlet 11 can be connected to the water outlet pipe of the heat exchange device, so that after the cold water is heated by the heat exchange device, hot water is generated to mix with the cold water in the water mixing valve 100 for water use.

[0042] In one embodiment, a partition 5 is arranged in the water mixing cavity 1, and the partition 5 divides the inside of the water mixing cavity 1 into a first chamber 51 and a second chamber 52 which are in communication with each other. One end of the first chamber 51 forms the water mixing inlet 14, one end of the second chamber 52 forms the water mixing outlet 12, and the other end 511 of the first chamber 51 and the other end of the second chamber 52 are in communication and jointly form the first connecting end 13. That is, the first chamber 51 communicates the hot water inlet 11 and the water outlet end 32 of the valve 3, and the second chamber 52 communicates the first chamber 51 and the water mixing outlet 12.

[0043] In the embodiment of the present application, the inner part of the mixed water cavity 1 is divided into the first chamber 51 and the second chamber 52 which are in communication with each other by arranging the partition 5 in the mixed water cavity 1, so that the cold water in the cold water cavity 2 flows to the first chamber 51 through the valve 3, and then mixes with the hot water entering through the hot water inlet 11. The mixed water flows to the second chamber 52, and then flows out through the mixed water outlet 12, so that the cold water and the hot water are mixed sufficiently, and the mixed water flowing out of the mixed water outlet 12 has more uniform temperature.

[0044] In one example, the partition 5 can divide the inner part of the mixed water cavity 1 into the first chamber 51 and the second chamber 52 which are in communication with each other in equal parts, and the partition 5 is arranged at the middle position of the mixed water cavity 1, which can facilitate processing.

[0045] In one example, the partition 5 can divide the inner part of the mixed water cavity 1 into the first chamber 51 and the second chamber 52 which are in communication with each other in unequal parts, for example, the first chamber 51 is larger than the second chamber 52, or the first chamber 51 is smaller than the second chamber 52. The size of the first chamber 51 and the second chamber 52 can be set according to the application, which is not limited in the embodiment of the present application.

[0046] In one example, so that almost all of the cold water entering the cold water cavity 2 mixes with the hot water entering through the hot water inlet 11 in the first chamber 51, a larger first chamber 51 and a smaller second chamber 52 can be arranged, and the size of the second chamber 52 can be sufficient for the mixed water to flow out.

[0047] In one embodiment, the partition 5 is arranged horizontally in the mixed water cavity 1 and extends towards the valve 3.

[0048] In one example, the partition 5 extends towards the valve 3 to 4 / 5-2 / 3 of the length of the mixed water cavity 1, so that the mixed water in the first chamber 51 flows to the second chamber 52. As a specific example, the partition 5 extends towards the valve 3 to 3 / 4 of the length of the mixed water cavity 1, and the mixed water in the first chamber 51 can flow to the second chamber 52 through the position of 1 / 4 of the length of the mixed water cavity 1 which is not separated by the partition 5, so that the mixed water flows out of the mixed water outlet 12. The length in the embodiment of the present application refers to the distance in the horizontal direction when the mixed water valve 100 is placed horizontally.

[0049] The partition 5 can be arranged in any way which does not affect the flow of the water in the first chamber 51 to the second chamber 52, which is not limited in the embodiment of the present application. As an example, the partition 5 can be arranged to be inclined upward or downward towards the valve 3. As an example, the partition 5 can be a flat plate, or other structures which are beneficial to the mixing of hot water and cold water, which is not limited in the embodiment of the present application.

[0050] In one example, the hot water inlet 11 and the mixed water outlet 12 can be arranged oppositely in the up-down direction of the mixed water cavity 1, or can be arranged in the vertical direction of the mixed water cavity 1, for example, the hot water inlet 11 is arranged on the upper side wall of the mixed water cavity 1, and the mixed water outlet 12 is arranged on the rear side wall of the mixed water cavity 1. Similarly, the cold water inlet 21 and the cold water outlet 22 can be arranged oppositely in the up-down direction of the cold water cavity 2, or can be arranged in the vertical direction of the cold water cavity 2, for example, the cold water outlet 22 is arranged on the upper side wall of the cold water cavity 2, and the cold water inlet 21 is arranged on the rear side wall of the cold water cavity 2. In one example, the mixed water outlet 12 can be arranged between the hot water inlet 11 and the first connecting end 13. The specific arrangement positions of the hot water inlet 11, the mixed water outlet 12, the cold water inlet 21 and the cold water outlet 22 are not limited in the embodiments of the present application.

[0051] In one embodiment, the flow channel 33 is movably arranged inside the valve 3. When the valve 3 is in the open state, the flow channel 33 communicates the water inlet end 31 of the valve 3 with the water outlet end 32 of the valve 3, and the water outlet of the flow channel 33 corresponds to the position of the other end 511 of the first chamber 51.

[0052] In one embodiment, the other end 511 of the first chamber 51 corresponds to and is located on the same horizontal plane as the water outlet of the flow channel 33. After the cold water of the cold water cavity 2 passes through the valve 3, it flows to the first chamber 51, so that almost all the cold water is mixed with the hot water of the first chamber 51 and then flows to the second chamber 52, ensuring sufficient mixing of the cold water and the hot water.

[0053] In one embodiment, the flow channel 33 is rotatably or slidably arranged inside the valve 3. The diameter of the water outlet of the flow channel 33 can be adjusted by controlling the rotation angle of the flow channel 33. Alternatively, the diameter of the water outlet of the flow channel 33 can be adjusted by adjusting the sliding position of the flow channel 33. It can be understood that the diameter of the water outlet of the flow channel 33 can also be adjusted by any other way, which is not limited in the embodiments of the present application. The embodiments of the present application rotatably or slidably arrange the flow channel 33 inside the valve 3, so that the diameter of the water outlet of the flow channel 33 can be adjusted, thereby adjusting the flow of the cold water cavity 2 into the mixed water cavity 1, so as to adjust the temperature of the mixed water to meet the needs of water use.

[0054] In one example, the outlet of the flow channel 33 corresponds to the position of the first connecting end 13, and the outlet of the flow channel 33 has a smaller diameter than the first connecting end 13. The outlet of the flow channel 33 is higher than the bottom of the first connecting end 13, so that the cold water entering the mixing water cavity 1 through the flow channel 33 can be mixed with the hot water first, ensuring that the water flowing out of the mixed water outlet 12 is mixed water. Adjusting the diameter of the outlet of the flow channel 33 can adjust the flow of the cold water cavity 2 into the mixed water cavity 1. The diameter of the outlet of the flow channel 33 is the largest from top to bottom, ensuring that the cold water entering the mixed water cavity 1 through the flow channel 33 is mixed with the hot water first, further ensuring that the water flowing out of the mixed water outlet 12 is mixed water.

[0055] In one embodiment, the other end 511 of the first cavity 51 has a smaller diameter than the outlet end 32 of the valve 3. The mixing state of the cold water and the hot water can be adjusted by adjusting the diameter of the outlet of the flow channel 33. For example, as shown in FIG. 5, the diameter of the outlet of the flow channel 33 can be adjusted to be smaller than or equal to the diameter of the other end 511 of the first cavity 51, so that almost all of the cold water is mixed with the hot water in the first cavity 51 and then flows to the second cavity 52, ensuring sufficient mixing of the cold water and the hot water. Figure 2 Figure 3 For example, as shown in FIG. 6, the diameter of the outlet of the flow channel 33 can be adjusted to be larger than the diameter of the other end 511 of the first cavity 51, so that part of the cold water flows to the first cavity 51 to mix with the hot water, and part of the cold water flows to the second cavity 52. Figure 4 For example, as shown in FIG. 7, the outlet of the flow channel 33 can be closed, so that the cold water cannot flow to the mixed water cavity 1 through the valve 3, and the hot water entering the hot water inlet 11 flows through the mixed water cavity 1 and then flows out of the mixed water outlet 12. In this case, the water flowing out is hot water.

[0056] In one embodiment, the second cavity 52 also communicates with the outlet end 32 of the valve 3. As shown in FIG. 8, when the diameter of the outlet of the flow channel 33 is the largest, the cold water flows to the second cavity 52 through the valve 3, so that the mixed water outlet 12 flows out of the cold water. Figure 4

[0057] ​​In one example, the mixing chamber 1 has a mixing inlet 14, a mixing outlet 12, and a first connecting end 13. The cold water chamber 2 has a cold water inlet 21, a cold water outlet 22, and a second connecting end 23. The hot water chamber 6 has a hot water inlet 11, which communicates with the mixing inlet 14. A valve 3 is disposed between the cold water chamber 2 and the mixing chamber 1. The inlet end 31 of the valve 3 communicates with the second connecting end 23, and the outlet end 32 of the valve 3 communicates with the first connecting end 13. When the valve 3 is open, the cold water chamber 2 is connected to the mixing chamber 1. The mixing chamber 1, the cold water chamber 2, and the valve 3 are disposed on the same plane. When the valve 3 is closed, the hot water entering through the hot water inlet 11 flows out through the mixing outlet 12 without mixing with the cold water. With valve 3 open, the hot water entering through hot water inlet 11 mixes with the cold water entering through cold water chamber 2 and flows out through mixing outlet 12, resulting in mixed water at a suitable temperature. When valve 3 is opened to its maximum outlet diameter in flow channel 33, the flow rate of cold water is relatively large. Furthermore, since mixing outlet 12 is connected to the atmosphere, and hot water inlet 11 is located on the side wall of mixing chamber 1, cold water flows directly to mixing outlet 12, resulting in cold water flowing out through mixing outlet 12.

[0058] In one example, the hot water inlet 11 can be positioned above the mixing water inlet 14.

[0059] In another example, the hot water inlet 11 can be located on one side of the mixing water inlet 14.

The cold water outlet 22 of the cold water chamber 2 of the mixing valve 100 is connected to the inlet pipe, the hot water inlet 11 of the hot water chamber 6 is connected to the outlet pipe, the cold water inlet 21 of the cold water chamber 2 is connected to an external first water supply pipe, and the mixing outlet 12 of the mixing chamber 1 is connected to an external second water supply pipe. As an example, the first water supply pipe is a tap water pipe, which can be fixedly connected to the cold water inlet 21, and the tap water pipe is provided with a flow regulating device for adjusting the flow rate of the cold water inlet. The second water supply pipe is a water pipe, which is connected to a faucet, and the water at a suitable temperature flowing from the mixing outlet 12 can be used by opening the faucet.
