Description

[0002] A mixing valve is a valve used to mix cold water and hot water, which needs to be connected to a cold water pipe and a hot water pipe simultaneously to achieve the purpose of mixing. Generally, the mixing valve also has the function of adjusting the water temperature. In some instant hot water dispensers, in order to achieve the purpose of constant temperature water output, a mixing valve is usually installed. After the mixing valve mixes high-temperature water and low-temperature water to reach the set temperature, it is then provided for users to drink.

[0003] However, the existing mixing valves are only simply used for the mixed use of cold and hot water in the water circuit.

[0046] The present invention also discloses a drinking water device. Referring to Figures 8 - 10 , it includes the above-mentioned mixing valve, and also includes a water supply device 6, a power device 7, a heat exchange device 8, and a heating device 9. Among them, the water supply device 6 is used to provide a water source, the power device 7 adopts a water pump, the heat exchange device 8 has two water inlets 81 and two water outlets 82, namely a hot water inlet 81a, a cold water inlet 81b, a hot water outlet 82a, and a cold water outlet 82b, and the heating device 9 is used to heat water.

[0047] Referring to Figures 8 - 10 , the water supply device 6 is connected to the cold water inlet 81b of the heat exchange device 8 through a water path, the cold water outlet 82b of the heat exchange device 8 is connected to the inlet of the heating device 9 through a water path, the outlet of the heating device 9 is connected to the hot water pipe 11a of the mixing valve through a water path, the hot water inlet 81a of the heat exchange device 8 is connected to the water path connecting the heating device 9 and the mixing valve at point a through a water path, the hot water outlet 82a of the heat exchange device 8 is connected to the cold water pipe 11b of the mixing valve, and in addition, the mixing pipe 11c of the mixing valve communicates with the water intake of the drinking water device.

[0048] Referring to Figure 8 , as a preferred embodiment of the drinking water device, the functional pipe 11d of the mixing valve is connected to the water path connecting the water supply device 6 and the heat exchange device 8 at point b through a water path. The power device 7 is installed on the water path connecting the water supply device 6 and the heat exchange device 8, and the power device 7 is arranged downstream of point b. The power device 7 is used to provide power for the water path so that water can flow in each water path.

[0049] Referring to Figure 9 , as another preferred embodiment of the drinking water device, the functional pipe 11d of the mixing valve is connected to the water path connecting the water supply device 6 and the heat exchange device 8 at point b through a water path.

[0050] Referring to Figure 10, as another preferred embodiment of the drinking water device, the functional pipe 11d of the mixing valve is connected to the water path connecting the heat exchange device 8 and the heating device 9 at point c. The power device 7 is installed on the water path connecting the heat exchange device 8 and the heating device 9, and the power device 7 is arranged downstream of point c.

[0051] The implementation principle and beneficial effects of the present invention are as follows: for the mixing valve, by setting the functional pipe 11d and the corresponding functional frame 13d, functional area 21d, functional hole 31d, functional groove 32d and related structural connection relationships, the mixing valve has two independent mixing water paths. In the two mixing water paths, one can be used as a normal drinking water path, and the other can be used as a functional water path for cleaning and high-temperature sterilization. By rotating the adjusting part 4 to different positions, the working state of the mixing valve can be switched from the closed state to the mixing state or the functional state according to needs, thus expanding the use purpose of the mixing valve and meeting the requirements for realizing complex functions inside the drinking machine.

[0052] For the drinking water device installed with the above mixing valve, during use, the power device 7 sends the water in the water supply device 6 into the heat exchange device 8 and the heating device 9. The boiled water after heating is divided into two paths. One path enters the hot water pipe 11a of the mixing valve, and the other path enters the heat exchange device 8 for heat exchange. After heat exchange, it enters the cold water pipe 11b of the mixing valve. The mixing valve mixes the two waters with different temperatures. If the mixing valve is kept in the second state or the third state, the mixed water is sent out through the mixing pipe 11c and can be used for the function of normal water intake and drinking. If the mixing valve is kept in the fourth state, the mixed water is sent out through the functional pipe 11d and then enters the water path between the water supply device 6 and the heat exchange device 8 again to form a circulation loop, which can realize functions such as cleaning and disinfection of the water path inside the drinking water device.

[0053] The above are only the implementation manners of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
