2 is a flowchart illustrating a method of operating a smart toilet in accordance with an embodiment of the present invention, which includes an automatic watering function and a clogging notification function (S10). Sensing the seating of the user by the pressure sensing unit (S100); A step S200 of setting a counter (not shown) to an initial value when the pressure is not sensed; A step S300 of the toilet detection unit 10 to detect a toilet operation; After the step S300, a step of comparing a value counted in a counter (not shown) with a setting value for operating a notification unit (not shown) (S400) and a step of counting the value counted in the counter (S500) of executing the step (S300) again after executing the water lowering and the water lowering in step (S400), wherein the step (S400) further comprises the step of, when the value counted in the counter (S450). In step S500, the counter (not shown) value is decreased by 1 when the water is lowered.

More specifically, the step S10 of sensing the level of the water level sensor 50 above a predetermined level is performed by sensing the level of water overflowing when the toilet is clogged by the level sensor 50 provided inside the toilet, When the water level sensor 50 operates and overflows, the notification unit (not shown) is operated (S450). In step S100, the user senses the user by the pressure sensor in the pressure sensing unit 20 (before the toilet is used) and the user senses that the user is out of the toilet (after using the toilet).

In step S200 to step S400, an initial value of a counter (not shown) is set in a control unit (not shown) when the pressure is not sensed (after using the toilet) in step S100.

Since the initial value has a condition to be compared with the set value of the step 400, the set value may be changed if the initial value is determined. Or vice versa, the initial value may also vary depending on the set value.

If it is determined that the condition of the toilet, which is the condition of step S300, is detected from the color sensor of the toilet bowl sensing unit 10 after step S200, the process goes to step S400, and if it is unsatisfactory, the water lowering device may not be operated.

For example, if the set value is set to 1, the initial value should preferably not be set to 2 or less and 3 or more.

If the initial value of the counter (not shown) is set to 2 or less, it is considered that clogging of the water in the automatic descent of the toilet is blocked, and it becomes troublesome to notify it.

In addition, if it is set to 3 or more, water may be wasted, and an appropriate initial value of 3 is most preferable.

The initial value and the set value are described as being the most preferable example, and are not limited.

If the condition of step S400, which is the step of comparing the set value with the initial value, is unsatisfactory, the process goes to step S500. In step S500, the value counted in the counter (not shown) Step is repeated until the counter value (not shown) is equal to the counted value.

Next, when the set value of the counter (not shown) agrees with the counted value, it is recognized that the toilet is blocked, and the process proceeds to step S450 of notifying the communication device, that is, the portable terminal or the PC.

After the step S450 of informing, the management unit or the next user who has received the notification may come to solve the clogging by using the tool.

Referring to FIG. 4, in a method of operating a smart toilet with an automatic watering function and a clogging notification function according to another embodiment of the present invention, step S300 includes steps S350 to S350 ), And transmits the determined used state to a notification unit (not shown).

That is, in step S350, the health state determining unit receives the color of the toilet bowl detected by the color sensor of the toilet bowl sensing unit 10, and transmits the color to the notification unit (not shown), that is, the portable terminal and the PC.

Step S350 is characterized in that the user can identify both the user's urine state and the urine.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. This is possible. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined by the equivalents of the claims, as well as the claims.
