Electronic toilet sitting detection method

Abstract

The invention discloses an electronic toilet sitting detection method and solves the problem of low accuracy in sitting identification and judgment. The technical scheme for solving the problem mainlycomprises the following steps: 1) an electronic toilet is started, and a pressure sensor detects a pressure value S on a toilet seat and transmits the pressure value S to a control circuit; 2) the control circuit compares the pressure value S with a preset minimum pressure value A, and if S is larger than or equal to the A, turn to the step 3), or otherwise, it is judged that the toilet seat is not occupied, and return to the step 1) to continue detection; 3) the control circuit compares the pressure value S with a preset maximum pressure value B, if the S is larger than B, enter the step 4),or otherwise, the electronic toilet enters a sitting state; and 4) the electronic toilet enters the sitting state, and an operation display portion starts an overweight abnormity alarm. The inventionalso discloses the electronic toilet. The method improves accuracy in sitting identification and judgment of the toilet, and reminds users to check sitting abnormal overweight.

Description

technical field [0001] The invention relates to the field of sanitary appliances, in particular to a method for detecting seating of an electronic toilet. Background technique [0002] With the development of science and technology, toilets are becoming more and more intelligent. Electronic toilets are generally equipped with a human body seating detection device to detect whether the human body is seated. There are mainly three types of seating detection devices on the market. [0003] The first is the micro switch mode, that is, a micro switch is set on the shaft portion of the toilet seat or the foot pad at the front end, and whether the state of the micro switch is changed by gravity to detect whether the seat is seated, but the seat position of the human body is different from the position of the micro switch. When the distance between the seat and the micro switch is very close, it is easy to judge that the seat cannot be seated. [0004] The second is the photoelectr...

Problems solved by technology

[0003] The first is the micro switch mode, that is, a micro switch is set on the shaft portion of the toilet seat or the foot pad at the front end, and whether the state of the micro switch is changed by gravity to detect whether the seat is seated, but the seat position of the human body is different from the position of the micro switch. When the distance between the seat and the micro switch is very close, it is easy to be unable to sit.

[0004] The second is the photoelectric ranging method, which is mainly to install a photoelectric detector in the middle of the body cover above the toilet seat, and emit infrared light through the detector. When a human body sits on the toilet seat, the infrared light will be reflected. When the detector receives the reflected infrared light, it is determined that someone is seated, but the detector has high requirements for the environment and the reflective surface. The brightness of the environment, the color and roughness of the reflective surface (clothes of the seated person) will all affect the seat detection. distance, causing poor seating

[0005] The third is the electrostatic method, which is mainly to install an electrostatic sensor inside the toilet seat that is in contact with the thigh of the human body. When someone sits down, it can be judged whether the human body is seated or not through the change of the electrostatic capacity. When there is an object like this, it will also change the electrostatic capacity, and the system will misjudge that someone is seated. At the same time, when there are other barriers between the electrostatic sensor and the person, the electrostatic capacity will basically remain unchanged even if someone is seated, resulting in a judgment that the seat is not seated.

[0006] The above three methods all have seat detection conditions, and the recognition of the seat detection device is limited, which reduces the accuracy of seat determination, resulting in the failure of the follow-up procedure of the electronic toilet to open and close normally.
