Detailed Description
The intelligent toilet bowl provided by the embodiment of the invention is formed by improving a traditional intelligent toilet bowl manufactured according to national standard GBT 34549 intelligent toilet bowl of sanitary ware, and comprises a toilet bowl body as shown in figure 5, an infrared sensor, a temperature sensor, a cleaning functional assembly, a flushing functional assembly and a controller for receiving signals of the sensor to control the assembly.
FIG. 1 is a flow chart of the intelligent toilet according to the embodiment of the present invention, which mainly comprises the following steps:
a) responding to a human body sitting signal, and operating a temperature sensor to detect the temperature of the water seal at least twice;
b) and operating the cleaning functional assembly, and implementing different cleaning functions according to the comparison result of the temperature difference and the preset value.
The human body sitting signal is generated by an infrared sensor or a pressure sensor for monitoring whether a human body is sitting or not when the human body is monitored to be sitting.
Specifically, the model of the infrared sensor can be selected as SMTIR9901, the installation position can be selected as a backrest (the monitoring area is the back of a human body) or a seat (the monitoring area is the hip of the human body), and when an infrared signal is partially shielded by the human body, the condition that a person sits on the seat can be judged; alternatively, the above determination may be made using a pressure sensor. The model of the pressure sensor can be selected from PT124G-210, the pressure sensor is arranged on the seat ring, and when the pressure on the seat ring is increased, the condition that a person is seated can be judged.
The temperature sensor can be a contact temperature sensor, such as PT100 platinum thermal resistor and LM75ADP, and is installed at the bottom of the trap, and the installation method is shown in FIG. 5: a fixing sleeve 21 is connected with the bottom of a trap through a nut 22 in a bolt mode (the fixing sleeve can also be fixed at the bottom of the trap through welding, bonding or sintering as an insert), the temperature sensor 1 is installed in the middle cavity of the fixing sleeve 21 through threaded connection, and a sealing piece 23 is pressed while the temperature sensor 1 is screwed in, so that water is prevented from entering the fixing sleeve 21. Alternatively, the temperature sensor may be a pyroelectric sensor, such as P228, LHl958, LHI954, RE200B, KDS209, PIS209, LHI878, PD632, mounted on the seat ring, aligned in the direction of the water seal.
The cleaning functional component realizes the cleaning function and specifically comprises a nozzle, which belongs to the prior art and is not described in detail in the specification.
Specifically, the operation of the temperature sensor for detecting the temperature of the water seal at least twice comprises the following steps:
a-1) detecting the initial temperature of the water seal;
a-2) delaying for a preset first time, and then detecting the real-time temperature of the water seal.
After a human body is seated, the initial temperature of the water seal is detected and used as the temperature information of the water seal before defecation of a user. After delaying the preset first time, the user is determined to have finished the excretion action, and the real-time temperature of the water seal is increased due to the existence of the excretion. The preset first time may be specifically selected to be 5 minutes.
The method for implementing different cleaning functions according to the comparison result of the temperature difference and the preset value comprises the following steps:
b-1) when the temperature difference is larger than a preset value, implementing a hip cleaning function;
b-2) when the temperature difference is less than or equal to the preset value, implementing the defecation assisting and cleaning function so as to stimulate the defecation of the user.
The temperature difference is the difference between the real-time temperature and the initial temperature. The initial temperature of the water seal is generally 20 ℃, the human excrement is generally 37 ℃, and generally, the temperature of the water seal is averagely increased by 3 ℃ after the human excrement enters the water seal. The preset value can therefore be chosen specifically to be 3 ℃. When the temperature difference is larger than 3 ℃, the normal defecation of the user can be judged, and the cleaning functional component is operated to automatically clean the hip of the user. When the temperature difference is less than or equal to 3 ℃, the defecation abnormity of the user can be judged, and at the moment, the cleaning functional component is operated, a small amount of water is used for spraying and washing the anus, and the sphincter and the rectum are stimulated to help the user defecate. Moreover, after the anus is sprayed and wetted, the anal fissure phenomenon caused by excessive defecation or anal dryness of the user can be relieved.
After responding to the human body seating signal, the method further comprises the following steps:
a-3) operating the washing functional component to wash the cleaning surface. At this time, the washing surface is washed with a small amount of water to form a water film on the surface of the washing surface, thereby preventing adhesion of feces.
After different cleaning functions are implemented according to the comparison result of the temperature difference and the preset value, the method further comprises the following steps:
c) responding to the human body off-seat signal, operating the washing functional assembly and washing the cleaning surface; the human body off-seat signal is generated by the infrared sensor or the pressure sensor when the human body is monitored to be off-seat. For the infrared sensor, when the infrared signal is changed from being shielded to not being shielded, the fact that a person is out of the seat can be judged; for the pressure sensor, when the pressure on the seat ring becomes small, the user can be judged to leave the seat.
The flushing functional component realizes flushing and cleaning of a cleaning surface, belongs to the prior art, and is not described in the specification.
When the temperature difference is less than or equal to the preset value, after the defecation assisting and cleaning function is implemented, the method further comprises the following steps:
b-3) delaying for a preset second time, and then detecting the real-time temperature of the water seal again.
After delaying the preset second time, the user is considered to finish the excretion action after spraying a small amount of water to the anus, and if the user has the excretion action, the real-time temperature of the water seal is increased due to the existence of the excretion. And c), detecting the real-time temperature of the water seal again, comparing the real-time temperature with the initial temperature, and executing the step b) again. The preset second time may be specifically selected to be 5 minutes.
