the invention (as shown in fig. 17 to 21) is used for adjusting the cold and hot water inlets 11 and 12 and the warm water cavity 14 or the mixed water flow passages 15, 16, 17 and 18 to be selectively conducted or completely closed by adjusting the switch valve 3; further giving the user more use experience; the method comprises the following steps: when the user needs to use warm water, the switch valve 3 is adjusted to a warm water gear so as to further discharge warm water; when cold water at normal temperature or hot water at high temperature is needed, the regulating switch valve 3 is regulated to a conventional gear (common gear), so that water at normal water temperature or high temperature can be discharged, at the moment, the warm water part is closed, the high-temperature hot water can not influence the temperature sensing element 21 of the warm water part, and the water can not be discharged, so that more use options are given to a user.
When the constant temperature water is needed to be used (as shown in figures 3 and 17), the regulating switch valve 3 is opened, cold water flows out of the pipeline, flows from the cold water inlet joint 41 to the cold water inlet runner 15, and hot water flows out of the water heater, and flows into the hot water inlet runner 16 through the hot water inlet joint 42; cold water and hot water respectively enter from the base 36 and the first water passing port 31 and the second water passing port 32 on the substrate 371, and at the moment, the cold water and the hot water enter from the stepped water passing ports 31 and 32 of the substrate 371 (namely, enter from small holes and flow from large holes); the driving unit 373 is rotated, the driving unit 373 drives the switching member 372 to rotate until the second water guiding portion 392 is respectively connected to the first water passing port 31 and the third water passing port 33, the third water guiding portion 393 is respectively connected to the second water passing port 32 and the fourth water passing port 34, and it should be noted that the second water guiding portion 392 and the third water guiding portion 393 are groove-like water guiding portions, and the areas of the second water guiding portion 392 and the third water guiding portion 393 can cover the two water passing ports; at this time, cold water enters from the first water passing port 31, passes through the second water guiding portion 392, flows into the cold water passing channel 17 from the third water passing port 33, and then enters the cold water inlet 241 of the thermostatic valve core 24; hot water also enters from the second water outlet 32, flows into the hot water flow passage 18 from the fourth water outlet 34 after passing through the third water guide 393, and then enters the hot water inlet 242 of the thermostatic valve core 24; the cold water and the hot water reach the constant temperature valve core 2 in the warm water cavity 14, the temperature sensing element 21 in the constant temperature valve core 2 senses the temperature and then automatically adjusts the position of the valve rod 23, the water temperature is adjusted to the set temperature by adjusting the water inlet areas of the cold water inlet 241 and the hot water inlet 242 on the valve body, and then the warm water flows out from the water outlet 13; in the above process, the first water guiding portion 391 of the switching member 372 and the first and second water passing ports 31 and 32 are in a staggered state, so that the water flow does not flow out from the mixed water outlet 38; the constant temperature water outlet state;
when normal temperature water (tap water temperature) or high temperature water is needed, the parts of the cold water and the hot water entering the regulating switch valve 3 are the same, and the description is not repeated, except that the driving unit 373 drives the switching piece 372 to rotate to a certain angle (as shown in fig. 10 and 19), so that the second water guide parts 392 and 393 are dislocated with the first water guide part 31 and the second water guide part 32, the third water guide part and the fourth water guide part 34 cannot enter the third water guide part 33 and the fourth water guide part 34, the high temperature water does not pass through the temperature water cavity 14 and the constant temperature valve core 2, and further the temperature water cavity 14 cannot be blocked due to excessive expansion after the temperature sensing element 21 senses the high temperature; at this time, the first water guiding part 391 partially covers the first and second water passing openings 31 and 32, so that the cold and hot water of the first and second water passing openings 31 and 32 flows in from the first water guiding part 391 and flows out through the mixed water outlet 38 communicated with the first water guiding part 391; of course, the above water mixture is mixed water, and only cold water or hot water can be discharged, and only a slight change in rotation angle is needed, and when cold water is discharged, the first water guide portion 391 (as shown in fig. 21) is only communicated with the first water passing port 31, so that cold water can be discharged; when high-temperature hot water (i.e., high-temperature water flowing out of the water heater) is needed, the first water guide 391 is only communicated with the third water passing port 33, so that hot water can flow out;
of course, when all the water is required to be closed (as shown in fig. 18), the first water guide 391 is turned to be displaced from the water outlet ports 31, 32, 33, 34 on the basis of the previous regular water discharge, and the closed state can be achieved.
