the controller 264 is further configured to control the electronic valve 100 according to the first temperature value, the second temperature value, the third temperature value and the target temperature value so that the second temperature value is equal to the target temperature value.

The first temperature value is the temperature value of tap water, i.e., the temperature value within the first flow channel 162. The second temperature value is an actual temperature value of the target water flowing out from the target water outlet 232, that is, a temperature value of the second through-flow channel 163. The third temperature value is a temperature value of the hot water, that is, a temperature value in the third through-flow channel 164, the target temperature value is a temperature value set by a user to flow out of the target water outlet 232, and the controller 264 may control the opening of the electronic valve 100 according to the first temperature value, the second temperature value, the third temperature value and the target temperature value to make the second temperature value equal to the target temperature value, thereby improving the user experience.

The controller 264 may be divided into two steps for quick and fine adjustment when adjusting the opening of the electronic valve 100. The opening of the electronic valve 100, which needs to make the second temperature value equal to the target temperature value, is calculated according to the first temperature value, the third temperature value and the target temperature value. On the basis, a certain space is reserved, and the initial opening degree is obtained. The electronic valve 100 is controlled to adjust the number of steps of the initial opening degree. And then detecting a second temperature value in real time, and adjusting the opening of the electronic valve 100 according to the second temperature value until the second temperature value is equal to the target temperature value.

For example: the current first temperature value is 20 degrees, the hot water temperature value is 60 degrees, the target temperature value set by a user is 40 degrees, if the second temperature value is 40 degrees according to three temperatures, the electronic valve 100 needs to be adjusted for 50 steps, a certain adjusting space is reserved, the initial adjustment opening degree can be 40 steps, the electronic valve 100 is controlled to move for 40 steps, the second temperature value is detected, and the opening degree of the electronic valve 100 is adjusted according to the second temperature value. If the second temperature value is smaller than the target temperature value at this time, the opening degree is continuously increased, and if the second temperature value is already larger than 40 degrees at this time, the opening degree of the electronic valve 100 is reduced.

The electronic valve 100 is controlled in a mode of combining the cold water temperature and the hot water temperature, so that the electronic valve 100 can be adjusted to the target step number as soon as possible, the second temperature value reaches the target temperature value as soon as possible, and the user experience is improved. And then the valve core of the electronic valve 100 is finely adjusted according to the second temperature value, so that the temperature value of the target water outlet 232 can be further fed back and adjusted, and the accurate temperature adjustment is realized.

In some embodiments, the second deflector segment 134a communicates with the second connector segment 134b through the first connector segment 132b, with the second connector segment 134b disposed in the first connector segment 132 b. In order to enable the second guide section 134a to communicate with the second connecting section 134b, the second guide section 134a needs to extend into the first connecting section 132b, and the connection between the second guide section 134a and the first connecting section 132b is sealed, so as to avoid the leakage of the first water flow channel 132.

In some embodiments, the first connecting section 132b is disposed at an angle to the first deflector section 132a, the second connecting section 134b is disposed at an angle to the second deflector section 134a, and the first deflector section 132a is disposed at an angle to the second deflector section 134 a.

Because the first connecting section 132b and the second connecting section 134b are overlapped, the first connecting section 132b and the second connecting section 134b can be regarded as a whole, the first water pipe assembly 130 approximately forms a three-dimensional coordinate system, and the extending directions of the whole of the first diversion section 132a, the second diversion section 134a, the first connecting section 132b and the second connecting section 134b are different, so that different waterway connections can be facilitated, and the installation of the electronic valve 100 is facilitated.

The first guide section 132a and the second guide section 134a being disposed at an angle means that the axis of the first guide section 132a and the axis of the second guide section 134a are disposed at an angle.

Since the second connecting section 134b is disposed in the first connecting section 132b, the first connecting section 132b is connected to the valve housing 120, and a radial seal ring can be used to seal between the first connecting section 132b and the valve housing 120.

The first connection section 132b and the valve housing 120 may be connected in a direction of a buckle, the first connection section 132b is inserted into the valve housing 120, and then the buckle is inserted into a junction of the first connection section 132b and the valve housing 120.

Likewise, the connection of one end of the second inducer 134a to the side wall of the second connector 134b may be considered as the axis of the second inducer 134a being disposed at an angle to the axis of the second connector 134 b.

It is easily understood that one end of the first connection section 132b communicates with the first connection passage 121, and the other end of the first connection section 132b is closed. Similarly, one end of the second connecting section 134b communicates with the second connecting channel 123, and the other end of the second connecting section 134b is also a closed structure.

Similarly, the first and

second flow segments

141a and 141b are each cylindrical, and the arrangement of the first and

second flow segments

141a and 141b at an angle means that the axis of the first flow segment 141a and the axis of the second flow segment 141b are arranged at an angle.

The end of the first flow section 141a is communicated with the third connecting channel 125, and the second flow section 141b is arranged at an included angle with the first flow section 141a, so that the second flow section 141b can be conveniently connected with a water pipe.

The fourth water flow channel 143 is mainly used for being connected with the heating module 300 and used for conveying cold water into the heating module 300 for heating.

The first flow section 141a, the second flow section 141b and the fourth flow channel 143 are all connected, and because the water pressure in the heating module 300 is high, the water entering the first flow section 141a preferentially enters the second flow channel 134 under the condition that the second flow section 141b is connected with the third flow channel 141, and is mixed with the hot water in the first flow channel 132, or directly enters the second flow channel 134 through the second connecting channel 123 and directly flows out.

The second water pipe assembly 140 serves as a three-way connection for introducing cold water into the valve housing 120 or into the heating module 300.

In some embodiments, the fourth water flow channel 143 is disposed at an angle to the first flow section 141a, and the fourth water flow channel 143 is disposed at an angle to the first flow section 141 a. Similarly, the fourth water flow channel 143 is also cylindrical, and the arrangement of the fourth water flow channel 143 at an angle with the first flow section 141a means that the axis of the fourth water flow channel 143 is arranged at an angle with the axis of the first flow section 141 a. The first flow-through section 141a, the second flow-through section 141b and the fourth flow-through passage 143 also form a three-dimensional coordinate, and the direction of the axis of the first flow-through section 141a is the same as the direction of the axis of the second flow-guiding section 134 a.
