Shower device capable of automatically controlling water outflow and control method thereof

[0029] Example one.

[0030] Such as figure 1 As shown, the shower device capable of automatically controlling water discharge of this embodiment includes a water outlet pipe 1, a shower head 2, a shower seat 3, and a manual water valve 4. It also includes a microprocessor 5 and a solenoid valve 6 for controlling water discharge. , A first sensor 7 for detecting whether the shower head 2 is fixed to the shower head 3, a second sensor 8 for sensing human body position information, the solenoid valve 6, the first sensor 7, and the second sensor 8 respectively It is electrically connected to the microprocessor 5. One end of the water outlet pipe 1 is connected to the water outlet of the water heater, and the other end is connected to the shower 2. The water heater can be electric water heaters, gas water heaters, solar water heaters, air energy water heaters and other water heaters. The shower seat 3 is fixed on the wall of the bathroom. The sprinkler 2 can be inserted into the slot of the shower seat 3. The microprocessor 5 can be arranged near the solenoid valve 6 or in the water heater. Generally, when people take a shower, if they hold the shower head 2, it means that the user wants to control manually, and if the shower head 2 is fixed on the shower seat 3, it means that the user wants to bathe, wipe soap, dry, and dress with both hands. Waiting for action, at this time hope to carry out automatic control. Therefore, in the present invention, the first sensor 7 detects whether the shower head 2 is fixed on the shower head 3, and then the second sensor 8 detects whether the human body is in the shower position. When people are taking a bath, the shower head 2 is fixed on the shower head 3. On the seat 3, after the water wets the body, when you need to wipe the soap (shower gel), you only need to take a step or a few steps and leave the shower position. The microprocessor 5 can control the solenoid valve 6 to stop the shower 2 spraying. When you need to spray water again, go to the shower position or remove the shower head 2 from the shower seat 3. The shower head 2 can spray water, so that you do not need to frequently control the manual water valve 4 during the bathing process. Easy to use. On the other hand, when people want to use the shower sprinkler for other purposes, such as flushing the bathroom, putting water in a basin, etc., they usually hold the shower 2, so the microprocessor 5 will not turn off the water by mistake. It is in line with people’s habits and convenient to use.

[0031] Further, the solenoid valve 6 is installed in the shower 2 or the water outlet pipe 1, and the solenoid valve 6 should be installed after the cold water is mixed with the hot water, instead of separately controlling the hot water.

[0032] Further, the first sensor 7 is disposed on the shower seat 3, and the first sensor 7 may be an infrared sensor, a pressure sensor, or the like.

[0033] Further, such as figure 1 As shown, the second sensor 8 is arranged on the shower base 3 or the shower 2, and the position of the second sensor 8 is determined according to the shower position, and its arrangement should be convenient for detecting whether the human body is in the shower position.

[0034] The second sensor 8 can also be arranged on the manual water valve 4 or the wall of the bathroom.

[0035] Further, the second sensor 8 is an infrared sensor.

[0036] Such as figure 1 As shown, the present invention also includes a third sensor 9 for detecting the switching state of the manual water valve 4, the third sensor 9 is connected to the microprocessor 5, and the manual water valve 4 can be determined by the third sensor 9 It is more important to determine whether the first sensor 7 and the second sensor 8 start to work. If the manual water valve 4 has not been closed for a long time after the bathing, you can make a sound or directly lock the solenoid valve 6 in the closed position , So that the shower 2 does not spray water to prevent inconvenience or waste of water during the next use. If the solenoid valve 6 is locked in the closed position, the solenoid valve 6 can be reopened by detecting the manual water valve 4 during the next use. Allow the shower to spray water.

[0037] Example two.

[0038] Such as figure 2 As shown, the control method of a shower device capable of automatically controlling water discharge includes the following steps.

[0039] a. After the manual water valve 4 is opened, the first sensor 7 detects whether the shower head 2 is placed on the shower head 3, and sends the detection information to the microprocessor 5. When the shower head 2 is placed on the shower head 3, enter the step b. When the shower 2 is not placed on the shower seat 3, proceed to step d. The first sensor 7 may be detected at regular intervals, such as every 1 second.

[0040] b. The microprocessor 5 controls the second sensor 8 to detect whether the human body is in the shower position, and sends the detection information to the microprocessor 5. When the human body is not in the shower position, go to step c, when the human body is in the shower position, enter Step d. Similarly, the second sensor 8 can also detect once every 1 second.

[0041] c. The microprocessor 5 controls the solenoid valve 6 to make the shower 2 stop spraying water, and the time to stop spraying water is less than T, go to step a, and the time to stop water spraying is greater than or equal to T, go to step e. The time T may be determined by the user, or may be determined according to general habits, for example, T may be 2 minutes or 5 minutes.

[0042] d. The microprocessor 5 controls the solenoid valve 6 to make the shower 2 start to spray water and return to step a.

[0043] e. End.

[0044] Through this control method, the present invention can detect whether the shower head 2 is fixed on the shower head 3 through the first sensor 7, and then detect whether the human body is in the shower position through the second sensor 8. When people are taking a bath, the shower head 2Fixed on the shower seat 3, after the water wets the body, when you need to wipe soap (shower gel), you only need to take a step or a few steps and leave the shower position, and the microprocessor 5 can control the solenoid valve 6 to make When the shower 2 stops spraying water and needs to spray again, go to the shower position or remove the shower 2 from the shower seat 3, the shower 2 can spray water, so that frequent control is not required during the bathing process Manual water valve 4, easy to use. If the shower stops spraying for a long time T, it may be that the user forgets to close the manual water valve 4 after washing and drying, putting on clothes, then the solenoid valve 6 should be locked so that the shower 2 does not spray water, and End the entire control process.

[0045] Further, the control method also includes detecting whether the manual water valve 4 is open (detecting the opening action, not the open state), and when it is detected that the manual water valve 4 is opened, that is, when the manual water valve 4 is opened again, proceed to step a , Restore the system to the initial state and restart control, at this time the solenoid valve 6 is in the open state. When it is detected that the manual water valve 4 is closed, go to step e and end.
