Referring to fig. 1, fig. 1 shows a main flowchart of a sterilization control method for an intelligent toilet provided by the present invention, the main structure of the intelligent toilet includes a cleaning nozzle, a self-cleaning nozzle, a sterilization water pipeline and a common water pipeline, the above structure works according to the flow shown in fig. 1, and the main process is as follows:
after receiving a cleaning instruction, the intelligent closestool starts to execute the steps of sterilization and cleaning, wherein the mode of receiving the cleaning instruction is generally that the intelligent closestool receives the cleaning instruction through a control device arranged on the intelligent closestool, and a user directly touches or presses a corresponding switch on the control device to convey the desire of cleaning the buttocks to the intelligent closestool. Of course, the control device may also be a related application on a remote controller or an intelligent terminal, and transmits an instruction to start cleaning to the intelligent toilet bowl in a wireless information transmission manner.
After the intelligent closestool receives the cleaning instruction, as the pipeline communicated with the cleaning spray head is a common water pipeline, the intelligent closestool is filled with common water and common water stored for a long time, bacteria are bound to accumulate in the intelligent closestool, and after the intelligent closestool is switched and communicated to the sterilizing water pipeline, the sterilizing water pushes the original common water and continuously discharges the common water for a certain time, so that the sterilizing treatment on the interior of the cleaning spray head before the cleaning spray head is cleaned is realized. The step is step 1, a period during which the cleaning nozzle switches to communicate with the sterilizing water pipeline is a first period, the first period is a preset value, and the first period can be adjusted according to actual needs, and in the embodiment, the first period is 2 s.
After the inside of the cleaning spray head is sterilized, the outside of the cleaning spray head is sterilized through the self-cleaning spray head. The self-cleaning spray head is also used for storing common water before sterilization, and after the cleaning spray head is switched and communicated with the sterilizing water pipeline for a first period, the sterilizing water pipeline is switched and communicated with the self-cleaning spray head, and the self-cleaning spray head can perform spray cleaning sterilization operation on the cleaning spray head. The step is step 1.1, the self-cleaning nozzle is switched to be communicated with the sterilizing water pipeline for a sixth period, the sixth period is a preset value and can be adjusted according to actual needs, and in the embodiment, the sixth period is 2 s.
After the self-cleaning nozzle finishes the sterilization treatment of the cleaning nozzle, the cleaning nozzle starts to perform the cleaning operation, namely step 2, the buttocks of the user are cleaned, the cleaning nozzle is communicated with a common water pipeline and is cleaned by using common water, the cleaning period is a second period, the second period is a preset value and can be adjusted according to actual needs, and in the embodiment, the second period is 2 min.
After the cleaning operation of the cleaning nozzle is completed, the cleaning nozzle needs to be sterilized again, namely step 3 and step 3.1. In step 3, the cleaning nozzle is switched from the common water communicating pipeline to the sterilizing water communicating pipeline and kept communicating for the third period, and the sterilizing water pushes the original common water and sterilizes the interior of the cleaning nozzle. And 3.1, executing step 3.1 after the step 3, switching the sterilizing water pipeline to be communicated with the self-cleaning spray head and continuing for a seventh period, and sterilizing the outside of the cleaning spray head by using the self-cleaning spray head. The third period and the seventh period are preset values, and can be adjusted according to actual needs, in this embodiment, the third period is 2s, and the seventh period is 2 s.
After step 3.1 is completed, the hip cleaning of the user and the sterilization treatment of the cleaning nozzle are completed, the user generally leaves at this time, and the inner wall of the intelligent closestool can be cleaned and sterilized. The steps of cleaning and sterilizing the inner wall of the intelligent closestool are step 3.2 and step 3.3, in step 3.2, the cleaning spray head is communicated with a common water pipeline and continues for the ninth period, and the cleaning spray head discharges common water to clean the inner wall of the intelligent closestool; in step 3.3, the cleaning spray head is communicated with the sterilizing water pipeline and continues for the tenth period, and the cleaning spray head discharges sterilizing water to sterilize the inner wall of the intelligent closestool. More specifically, the cleaning nozzle is designed into a nozzle structure capable of rotating 360 degrees, the rotation is controlled by a corresponding motor, the cleaning nozzle starts to rotate from an initial position and stops after selecting a circle in the process of discharging common water and sterilizing water, and the common water and the sterilizing water can all-directionally contact the inner wall of the closestool in the rotating process of the cleaning nozzle, so that the inner wall of the closestool can be cleaned and sterilized without dead angles. Particularly, in the process of discharging common water, the cleaning spray head can rotate for two weeks, then the sterilizing water is discharged and rotates for one week, the inner wall of the intelligent closestool is firstly sprayed with the common water twice to improve the cleanness degree of the inner wall, then the sterilizing water is sprayed for sterilization, and after the sterilizing water is discharged, the operation of discharging the common water is not carried out, so that the phenomenon that the inner wall of the closestool loses the sterilization protection effect due to the fact that the sterilizing water is flushed completely by the common water is avoided.
After step 3, step 4 is also optionally performed as appropriate. If the intelligent closestool does not receive the cleaning instruction again in the fourth period after the step 3 is completed, controlling the cleaning spray head to switch and communicate with the common water pipeline for the fifth period, so that the cleaning spray head is filled with common water instead of sterilizing water when not used. The sterilizing effect of the sterilizing water is weakened if the sterilizing water is stored in the cleaning spray head for a long time, and the sterilizing cost is not reduced, so that the sterilizing water is replaced by the common water when the intelligent closestool is not used for a long time, and the sterilizing treatment can be carried out by using the new sterilizing water when the intelligent closestool is used next time. In the present embodiment, the fourth period is 30min, and the fifth period is 3 s.
Further, it should be noted that the seventh period should be smaller than the fifth period, and the sum of the seventh period, the ninth period, and the tenth period should also be smaller than the fifth period, so that confusion of operation timing is avoided.
In the intelligent closestool sterilization control method provided by the invention, in order to achieve the sterilization purpose, the sterilization water is used as a sterilization substance. The sterilizing water is obtained by arranging an electrolysis device, and generating sterilizing ions by electrolysis in common water to form the sterilizing water, wherein the sterilizing ions can be silver ions or chloride ions and the like. The electrolysis device forms an electrolytic cell in the common water, and after the electrolysis device is electrified, the common water can be converted into the sterilizing water after corresponding ions with the sterilizing effect are electrolyzed, and the sterilizing water is communicated with the cleaning spray head, the self-cleaning spray head or the cleaning spray head through independent pipelines. Meanwhile, the sterilizing water is formed by utilizing an electrolysis mode, and the concentration of sterilizing ions in the sterilizing water can be adjusted by controlling the electrolysis time duty ratio of the electrolysis device, and the specific principle of the application is as follows: the electrolytic cell only runs when being electrified, namely, the corresponding bactericidal ions can be generated only when being electrified, and the quantity of the generated bactericidal ions can be controlled by controlling the duration and the frequency of the electrification, so that the concentration of the bactericidal ions in the bactericidal water is adjusted; the duration and frequency of the energization can be expressed by the electrolysis time duty ratio, which means the duration of the energization within a preset unit time, for example, the preset unit time is 1s, and the duty ratio is 25%, which indicates that 1/4s of the time within 1s is the energization time.
Because the sterilizing water has the danger of contacting with the human body, the concentration of the sterilizing water must be ensured not to exceed the safe value that the human body can bear, and meanwhile, in order to ensure that the sterilizing water has a certain sterilizing effect, the concentration of the sterilizing water is required not to be too low, so that the concentration of the sterilizing water must be regulated and controlled, namely the electrolysis time duty ratio of the electrolysis device is controlled. Meanwhile, the concentration of the sterilizing water is related to various factors, such as the flow value, the temperature value and the total soluble solid value of the sterilizing water, and the sterilizing water is supplied to different types of spray heads, wherein the sterilizing water required by the cleaning spray head has the lowest concentration, the self-cleaning spray head is higher, and the cleaning spray head has the highest concentration, and the concentration of the sterilizing water also needs to be adjusted according to different types of the spray heads communicated with the sterilizing water pipeline.
Wherein the sterilizing water concentration is positively correlated with the flow rate value of the sterilizing water, negatively correlated with the temperature value of the sterilizing water, and negatively correlated with the total soluble solids of the sterilizing water, and the control of the sterilizing water concentration essentially controls the electrolysis time duty ratio of the electrolysis device, so that the electrolysis time duty ratio is positively correlated with the flow rate value of the sterilizing water, negatively correlated with the temperature value of the sterilizing water, and negatively correlated with the total soluble solids of the sterilizing water.
Specifically, in this embodiment, the sterilizing water pipeline of the intelligent toilet needs to be provided with a flow sensor, a temperature sensor and a total soluble solids sensor, which are respectively used for detecting the flow value, the temperature value and the total soluble solids value of the sterilizing water, and after the real-time flow value, temperature value and total soluble solids value are obtained, the corresponding flow correction coefficient, temperature correction coefficient and total soluble solids correction coefficient can be determined according to the data and the corresponding flow correction coefficient comparison table, temperature correction coefficient comparison table and total soluble solids coefficient comparison table, which are shown in fig. 2.
In addition, since the concentration control of the sterilizing water is also related to the type of the head with which the sterilizing water line is communicated, it is also necessary to determine the head correction coefficient for each head.
As shown in fig. 2, the top table is a flow correction coefficient comparison table, and the contents thereof are: when the flow value is less than or equal to 350mL/min, the flow correction coefficient is 0.8; when the flow value is more than 350mL/min and less than 500mL/min, the flow correction coefficient is 1; when the flow value is more than or equal to 500mL/min, the flow correction coefficient is 1.2.
The second upper table is a temperature correction coefficient comparison table, and the contents thereof are: when the temperature value is less than or equal to 15 ℃, the temperature correction coefficient is 1.2; when the temperature value is more than 15 ℃ and less than 30 ℃, the temperature correction coefficient is 1; when the temperature value is more than or equal to 30 ℃, the temperature correction coefficient is 1.2.
The third upper table is a coefficient of total dissolved solids comparison table, which contains: when the total soluble solid content value is less than or equal to 50mg/L, the total soluble solid content correction coefficient is 1.2; when the total soluble solid value is more than 50mg/L and less than 150mg/L, the total soluble solid correction coefficient is 1; when the total soluble solid content value is 150mg/L or more, the total soluble solid content correction coefficient is 0.8.
The lowest table is a nozzle correction coefficient comparison table, and the contents of the table are as follows: when the sterilizing water pipeline is communicated with the cleaning spray head, the correction coefficient of the spray head is 1; when the sterilizing water pipeline is communicated with the self-cleaning spray head, the correction coefficient of the spray head is 1.5; when the sterilizing water pipeline is communicated with the cleaning spray head, the correction coefficient of the spray head is 2.
The calculation formula of the electrolysis time duty ratio is represented by the following relation of the electrolysis time duty ratio, a flow correction coefficient, a temperature correction coefficient, a total soluble solid correction coefficient and a spray head type correction coefficient: preset duty cycle flow correction coefficient, temperature correction coefficient, total dissolved solids correction coefficient, spray head correction coefficient. Wherein the preset duty cycle can be set according to actual conditions.
In one embodiment, the preset duty cycle is set to 10% o, representing 10ms of closing the power supply to the electrolysis device every 1 s. In this example, the electrolysis time duty cycle (symbol is denoted by D) is 10 ‰ m × k × p ×, where m, k, p, and q are a total dissolved solids correction coefficient, a showerhead correction coefficient, a flow rate correction coefficient, and a temperature correction coefficient, respectively. If m is 1, k is 1.5, p is 0.8 and q is 1, the electrolysis time duty ratio in this case D is 10 ‰ 1.5 × 0.8 ═ 1 ‰ 12 ‰, i.e. 12ms of current flow per 1s of time. Of course, in other embodiments, the real-time calculation and adjustment can be performed according to the real-time monitored condition of the sterilizing water and the type of the connected spray head.
In order to realize the intelligent closestool sterilization control method, the invention also provides an intelligent closestool which comprises a cleaning spray head, a self-cleaning spray head, a first switching valve, a second switching valve, a third switching valve, a sterilized water pipeline, a common water pipeline, an electrolysis device, a controller and a sensor.
The electrolysis device is arranged in the sterilizing water pipeline and forms an electrolytic cell after being electrified, ions with sterilizing effect are generated by utilizing the principle of electrolysis, and therefore the common water entering the sterilizing water pipeline is converted into the sterilizing water.
The sensor comprises a flow sensor, a temperature sensor and a dissolved solid total amount sensor, and is respectively used for detecting the sterilizing water flow, the temperature and the dissolved solid total amount in the sterilizing water pipeline and transmitting the data to the controller for processing.
The controller is electrically connected with the sensor, the electrolysis device, the first switching valve, the second switching valve and the third switching valve. The first switching valve, the second switching valve and the third switching valve are respectively used for realizing the communication of the cleaning spray head, the self-cleaning spray head and the sterilizing water pipeline or the common water pipeline, the three switching valves can be integrated to form a large switching device, are respectively connected into the sterilizing water pipeline and the common water pipeline, and are controlled by the controller to realize the switching. The controller records control instructions for the first switching valve, the second switching valve and the third switching valve while controlling the switching valves to operate so as to judge the type of the spray head communicated with the sterilizing water pipeline and determine the corresponding spray head correction coefficient.
The storage device in the controller is pre-stored with the numerical value of the preset duty ratio, and is also pre-stored with a flow correction coefficient comparison table, a temperature correction coefficient comparison table, a total soluble solid amount correction coefficient comparison table and a spray head correction coefficient comparison table, and the controller can read the data and perform calculation processing.
Specifically, the controller queries the corresponding flow correction coefficient comparison table, temperature correction coefficient comparison table, and total soluble solid amount correction coefficient comparison table according to the flow value, temperature value, and total soluble solid amount value transmitted by the sensor, and when the flow value, temperature value, and total soluble solid amount value fall into a specific interval in the corresponding correction coefficient comparison table, the controller can obtain the corresponding correction coefficient. Meanwhile, the controller also judges the type of the spray head communicated with the sterilizing water pipeline at present according to the recorded control instruction of the switching valve, and inquires in a spray head correction coefficient comparison table to obtain a corresponding spray head correction coefficient.

Specifically, the controller counts the total number of times that the first switching valve, the second switching valve and the third switching valve are communicated with the sterilizing water pipeline, and when the total number of times reaches a preset number of times, the controller counts again and controls the current direction of the electrolysis device to change. The preset times are preset values and can be adjusted according to actual needs, in the embodiment, the preset times are set to be 20 times, the preset times are the total times of the communication of the first switching valve, the second switching valve and the third switching valve with the sterilizing water pipeline, and are not counted respectively, so that the corresponding time for keeping the sterilizing water pipeline unblocked is obtained, and the running time of the electrolysis device is obtained in sequence. After the current direction of the electrolysis device is controlled to change, the polarity of the electrode of the electrolysis device is changed, so that the phenomenon that the single electrochemical reaction is generated to influence the service life of the electrolysis device is avoided.
