The utility model provides a mixing water tank 10 and a zero cold water and hot water system 100, and aims to provide a mixing water tank 10 which does not need to be preheated and waiting in advance and has low air consumption.

The specific structure of the mixing tank 10 and the zero cold water and hot water system 100 of the present utility model will be described below:

referring to fig. 1 to 5 in combination, in an embodiment of the present utility model, the water mixing tank 10 includes a tank 11, a hot water inlet branch 12, a hot water outlet branch 13, a cold water inlet branch 14, and a first connection branch 15; a water storage cavity 11a is formed in the tank body 11; the water inlet of the hot water inlet branch 12 is used for communicating with the water outlet of the water heater 20, and the water outlet of the hot water inlet branch 12 is communicated with the water storage cavity 11a; the water inlet of the hot water outlet branch 13 is communicated with the water storage cavity 11a, and the water outlet of the hot water outlet branch 13 is communicated with a water point 50; the water inlet of the cold water inlet branch 14 is used for communicating with a cold water pipe 40, and the water outlet of the cold water inlet branch 14 is communicated with the hot water outlet branch 13; the water inlet of the first connection branch 15 is communicated with the hot water inlet branch 12, the water outlet of the first connection branch 15 is communicated with the hot water outlet branch 13, a first control valve 151 is arranged on the first connection branch 15, and a second control valve 141 is arranged on the cold water inlet branch 14.

It can be appreciated that in the water mixing tank 10 according to the present utility model, when the tank 11 is not in use, the water flow stored in the water storage chamber 11a can be heated by the heater 114; when the user uses hot water and the water flow (low-temperature water) discharged from the water heater 20 does not reach the preset temperature, the first control valve 151 is in a normally open state, the second control valve 141 is in a normally closed state, at this time, the low-temperature water discharged from the water heater 20 can flow to the water storage cavity 11a and the first connection branch 15 through the hot water inlet branch 12 at the same time, the water flow entering the water storage cavity 11a can flow to the hot water outlet branch 13 after converging with the high-temperature water stored in the water storage cavity 11a, and the water flow flowing out of the water storage cavity 11a can flow to the water point 50 from the hot water outlet branch 13 after converging with the water flow flowing out of the first connection branch 15 to form high-temperature water; when the water flow (high-temperature water) discharged from the water heater 20 reaches the preset temperature, the first control valve 151 is in a normally closed state, and the second control valve 141 is in a normally open state, at this time, the high-temperature water discharged from the water heater 20 can flow to the water storage chamber 11a through the hot water inlet branch 12 to flow to the hot water outlet branch 13 after converging with the high-temperature water in the water storage chamber 11a, and at the same time, the cold water flowing in from the cold water pipe 40 can flow to the hot water outlet branch 13 through the cold water inlet branch 14 to flow to the water point 50 from the hot water outlet branch 13 after converging with the high-temperature water in the hot water outlet branch 13.

Therefore, whether the water flow discharged from the water heater 20 reaches the preset temperature or not, the water flow finally flows out of the hot water outlet branch pipe can reach the use temperature required by a user, the user can directly obtain the high-temperature water without waiting for the preheating time, and compared with the heating mode of adopting the circulating water pump and the water return valve, the scheme can realize zero cold water consumption of the water consumption point 50 by setting the mode of the mixing water tank 10, does not need to frequently start the water heater 20 for heating, can prolong the service life of the water heater 20, and can reduce the air consumption.

In addition, the cold water flowing in through the cold water inlet branch 14 and the hot water flowing out of the hot water outlet branch 13 are converged and then flow out, so that water with various temperatures can be output from the hot water outlet branch 13, the functionality of the mixed water tank 10 is improved, and the use comfort of a user is improved. When the user needs the water with lower temperature, the cold water entering from the cold water inlet branch 14 and the high temperature water in the water storage cavity 11a can be outwards flowed after being converged by the hot water outlet branch 13, so that the functionality of the mixed water tank 10 is improved.

In addition, in the process of using hot water, the water entering from the hot water inlet branch 12 flows out after being converged with the water in the water storage cavity 11a, so that the water in the water storage cavity 11a can be continuously circulated, and the cleanliness of the used water can be improved. In addition, when in use, since the water flowing out of the water heater 20 is converged with the water stored in the water storage cavity 11a, the water in the water storage cavity 11a can be kept at a higher temperature all the time in the use process, so that the zero cold water consumption of the water consumption point 50 can be realized when the water consumption point 50 is opened and closed in a short time, the water consumption temperature is stable, and the use comfort of a user can be improved.

And, by communicating the hot water inlet branch 12 and the hot water outlet branch 13 using the first connection branch 15, and providing the first control valve 151 on the first connection branch 15, it is possible to reduce the amount of water having low temperature water entering the water storage chamber 11a, and it is possible to prevent the temperature of the water in the water storage chamber 11a from being lowered to a very low temperature, so that the water flow in the water storage chamber 11a is maintained at a high temperature. In terms of the change, when it is required to control the water temperature in the water storage chamber 11a to be above 60 ℃, if the first connection branch 15 is not provided between the hot water inlet branch 12 and the hot water outlet branch 13, then the low-temperature water entering from the hot water inlet branch 12 will all flow into the water storage chamber 11a to be merged with the water flow in the water storage chamber 11a, so if it is required to control the water temperature in the water storage chamber 11a to be above 60 ℃, it is required to provide a larger volume of the tank 11, for example, it is required to provide more than 8L of the tank 11, so that enough high-temperature water is stored in the water storage chamber 11a of the tank 11 to be merged with a large amount of low-temperature water, and then the water temperature can be controlled to be above 60 ℃; the first connecting branch 15 is used for communicating the hot water inlet branch 12 and the hot water outlet branch 13, and the first connecting branch 15 is provided with the first control valve 151, so that low-temperature water entering from the hot water inlet branch 12 can partially flow to the hot water outlet branch 13 directly through the first connecting branch 15, and the amount of water flowing into the water storage cavity 11a directly is reduced, so that the high-temperature water in the water storage cavity 11a is only converged with a small amount of low-temperature water, and if the water temperature in the water storage cavity 11a is controlled to be more than 60 ℃, only a tank 11 with a small volume, for example, a tank 11 with about 6L is arranged.

Therefore, the cold water inlet branch 14 and the first connecting branch 15 can share the second connecting branch 16, so that the use of pipelines can be reduced, and the investment of preparation cost can be reduced.

In some embodiments, a three-way valve may be provided at the water inlet of the second connection branch 16, such that two water inlets of the three-way valve communicate with the water outlet of the cold water inlet branch 14 and the water outlet of the first connection branch 15, respectively, and such that the water outlet of the three-way valve communicates with the water inlet of the second connection branch 16.
