Description

Technical Field

[0001] The invention relates to the technical field of sanitary ware, in particular to a method for controlling self-drying of a toilet seat and a toilet. Background Art

[0002] Smart toilets originated in the United States and were used for medical and elderly care. They were originally equipped with a warm water cleaning function. Later, sanitary ware companies in South Korea and Japan gradually introduced the technology and began to manufacture them, adding a variety of functions such as toilet seat heating, warm water cleaning, warm air drying, and sterilization. Among them, the warm water cleaning of smart toilets has a massage effect and promotes blood circulation, providing a completely clean feeling and preventing bacterial growth.

[0003] For example, the prior art CN219126157U patent application discloses a device for washing the buttocks after defecation and urination, comprising an outer shell, the lower side of the outer shell is open, a flushing unit and a drying unit are arranged on the outer shell, the flushing unit comprises a water storage part, a water pipe is connected to the water storage part, the other end of the water pipe away from the water storage part extends to the upper side of the outer shell and is flexibly connected to a straight-line nozzle, the water storage part comprises at least one syringe, the syringe is embedded in the surface of the outer shell, the nozzle of the syringe is provided with a water pipe, all the water pipes are connected to the nozzle after being collected, and the syringe quickly sprays water to wash the buttocks by squeezing the piston. In the prior art, when the syringe quickly sprays water to wash the buttocks by squeezing the piston, the water pressure sprayed by the syringe is relatively large, and the water will splash out after colliding with the buttocks and washing, and residual water will be left on the surface of the toilet seat and the rear of the toilet seat, and the next user needs to wipe it when using it, and will feel uncomfortable, and it is unhygienic, easy to breed bacteria and leave water stains.

[0004] In order to solve the above problems and provide users with a clean and hygienic toilet environment, the toilet can clean and dry the toilet seat after the user uses the toilet. For example, the prior art CN215502703U patent application discloses a toilet that can flush and dry the toilet seat, including a toilet base, a toilet seat is arranged on the upper end surface of the toilet base, a heating plate is arranged inside the toilet seat, a toilet cover is arranged on the upper end surface of the toilet seat, an exhaust hole is arranged on the inner side of the toilet cover, a box body is arranged on one side of the toilet cover, a water pump is arranged inside the box body, a first water inlet is arranged on one side of the water pump, a first water outlet is arranged on the other side of the water pump, a second water inlet is arranged on one side of the first water inlet, a second water outlet is arranged on one side of the first water outlet, a support rod is arranged on one side of the box body, a controller is arranged at one end of the support rod, a power plug is arranged on one side of the controller, a water storage bin is arranged on one side of the toilet base, a water inlet pipe is arranged on one side of the water storage bin, a manual button is arranged on the upper end surface of the water storage bin, and a motor is arranged on one side of the water pump. In this prior art, after the toilet seat is flushed, the heating plate continues to work after being connected to the power supply, and stops heating after reaching a certain temperature. The heat emitted by the heating plate inside the toilet seat dries the remaining water. In this prior art, after the user uses the toilet, the toilet will automatically turn on the cleaning and drying mode of the toilet seat indiscriminately. Even if the user does not need to dry it, the cleaning and drying mode will be turned on, which causes confusion for the user and is not environmentally friendly. Summary of the invention

[0005] The purpose of the present invention is to provide a control method for self-drying of toilet seats, so as to solve the problem in the prior art that it is impossible to judge whether the toilet seat needs to be dried. Whether the drying needs to be started is judged according to the actual water accumulation on the surface of the toilet seat, thereby saving energy consumption.

[0006] In order to achieve the above object, the present invention adopts the following technical scheme: a control method for self-drying of toilet seat, comprising the following contents:

[0007] S1. After recognizing that the user has left the toilet seat, determine whether the user has used the cleaning function. If yes, enter S2, if not, standby;

[0008] S2. Calculate the amount of water Q on the rear surface of the toilet seat, turn on the heating function of the toilet seat, and dry the water on the surface of the toilet seat.

[0009] After adopting the above technical solution, the present invention has the following advantages: by identifying whether the user has left the toilet seat and whether the user has used the cleaning function, only after the user has used the cleaning function and left, the system can automatically respond to the user's behavior and enter the next step of operation, avoiding unnecessary energy consumption and providing an intelligent user experience. At the same time, the control method can reasonably calculate the activation time of the heating function according to the amount of water accumulated in the toilet Q, which not only ensures that the accumulated water on the surface of the toilet seat is dried, and the toilet seat is not easy to breed water stains and bacteria, but also automatically stops heating after drying, saving energy consumption. The user does not need to perform unnecessary operations, and the user does not need to judge whether the accumulated water on the toilet seat needs to be dried, providing the user with a more intelligent and convenient user experience.

[0010] Further, after S1, the process enters S1-1 to determine whether the distance L between the user's buttocks and the rear of the toilet seat when the user is sitting has reached a set distance value L0. If so, the process enters S1-2. If not, the process enters standby mode.

[0011] S1-2. Determine whether the time length T that the user uses the cleaning function reaches the set time length value T0. If so, enter S2, if not, wait.

[0012] Using the above-mentioned technical solution, when the system recognizes that the user has used the washing function, the control method determines whether water will splash onto the toilet seat through the distance L from the user's buttocks to the back of the toilet seat and the length of time T that the user uses the washing function, thereby determining whether the heating function of the toilet seat needs to be turned on to save energy.

[0013] Furthermore, the estimated amount of water Q accumulated on the rear surface of the toilet seat in S2 is calculated based on L and T. The larger L is and the larger T is, the larger the amount of water Q is. Using the aforementioned technical solution, L is the distance from the user's buttocks to the rear of the toilet seat when the user is seated. The larger L is, the farther the user's buttocks are from the rear of the toilet seat, that is, the larger the gap between the user's buttocks and the toilet seat is, which means that the more water is splashed when the user uses the washing function, and therefore the larger the amount of water Q accumulated on the rear surface of the toilet seat. T is the length of time the user uses the washing function. The larger T is, the longer the user uses the washing function, and the larger the amount of water Q splashed on the rear surface of the toilet seat. Therefore, through calculations based on L and T, the amount of water Q accumulated on the rear surface of the toilet seat can be estimated more accurately, thereby more accurately controlling the opening time of the toilet seat and saving energy consumption.

[0014] Furthermore, Q=a(L-L0)*(T-T0), a≥0, where a is the deviation coefficient. By adopting the aforementioned technical solution, the amount of water Q on the rear surface of the toilet seat can be accurately calculated, thereby accurately controlling the duration of the heating of the toilet seat. By introducing the deviation coefficient a, the calculation of the amount of water Q can be actually adjusted. a can be adjusted according to the characteristics of toilet seats of different models, the habits of different users, and the use environment. By reasonably adjusting the value of a, the amount of water Q can be better predicted, thereby achieving more accurate self-drying control, so that the self-drying function is more in line with the actual needs of users.

[0015] Furthermore, the amount of water Q accumulated on the rear surface of the toilet seat in S2 is estimated based on the total amount of water Q used for the washing function. 总 And the amount of water added to the toilet Q 增 To calculate, the total amount of water used by the cleaning function Q 总 The flow meter on the toilet lid is used to obtain the water volume before the flushing function is used. The water volume after the flushing function is used is V0, and the water volume after the flushing function is used is V1. 增 =V1-V0, Q=Q 总 -Q 增 The above technical solution is adopted to obtain the total water volume Q used by the washing function by using a flow meter. 总 The flow meter can accurately measure the amount of water used by the flushing function, rather than estimating or based on a fixed value, so it can more accurately predict the amount of water accumulated on the rear surface of the toilet seat Q, by monitoring the difference in the amount of water in the toilet before and after the flushing function is used, that is, the amount of water added to the toilet Q 增 , the amount of water Q splashed onto the surface of the toilet seat can be indirectly obtained, and a more accurate calculation of the amount of water Q can be achieved, thereby obtaining the accurate opening time.

[0016] Furthermore, the amount of water Q estimated on the rear surface of the toilet seat in S2 takes into account the amount of residual water inside the toilet and on the user's body surface. By adopting the above technical solution, by subtracting the amount of residual water inside the toilet and on the user's body surface, the self-drying control is made more intelligent and accurate, and the user does not need to worry about the problem of residual water stains, which improves the comfort and convenience of use, and can avoid unnecessary drying time. In this way, the toilet seat does not require additional heating and drying, which saves energy consumption, ensures that the toilet seat is fully dried, prevents water from remaining on the surface of the toilet seat, reduces the possibility of bacteria and other microorganisms, and improves the hygiene of the toilet seat.

[0017] Furthermore, the estimated amount of water Q on the rear surface of the toilet seat in S2 is obtained by calculating the number and frequency of water droplets splashing onto the rear surface of the toilet. By adopting the above technical solution, the amount of water Q on the rear surface of the toilet seat can be accurately obtained by monitoring the number and frequency of water droplets splashing onto the rear surface of the toilet, and the duration of heating can be controlled more accurately.

[0018] Furthermore, the number and frequency of water droplets are obtained by detecting the deformation data of the rear surface of the toilet by a pressure sensor. With the above technical solution, the pressure sensor can accurately sense tiny deformations, thereby capturing and measuring the landing of water droplets in real time, accurately measuring the number and frequency of water droplets, and the pressure sensor can sense deformation data in real time, so it can quickly respond to user behavior, calculate the amount of accumulated water Q in time, and start the self-drying function, so that the toilet can be quickly dried after the user finishes using it, improving the efficiency of self-drying.

[0019] Furthermore, if the washing function has different strength levels, Q is calculated in association with the strength of the washing function level, and Q is proportional to the strength of the washing function level. 总 Increase, thus affecting the amount of water accumulated on the toilet seat surface Q 增 More, the Q is associated with the gear intensity of the washing function to calculate, so that the heating time can be accurately adjusted to ensure that the toilet seat is fully dried, reduce power consumption, and provide users with a smarter and more convenient experience.

[0020] The present invention also provides a toilet, which is controlled by the toilet seat self-drying control method described in any of the above technical solutions. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The technical solution of the present invention is described in detail with specific embodiments below. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0030] Embodiment 1:

[0031] like Figure 1 As shown, the present invention provides a method for controlling toilet seat self-drying, comprising the following contents:

[0032] S1. After recognizing that the user has left the toilet circle 1, determine whether the user has used the cleaning function. If yes, enter S2, if not, then standby;

[0033] S2. Expect the amount of water Q on the rear surface of the toilet seat 1, turn on the heating function of the toilet seat 1, and dry the water on the surface of the toilet seat 1.

[0034] In this embodiment, by identifying whether the user has left the toilet seat 1 and whether the user has used the cleaning function, the system can automatically respond to the user's behavior and enter the next step only after the user has used the cleaning function and left, avoiding unnecessary energy consumption and providing an intelligent user experience. At the same time, the control method reasonably calculates the opening time T2 of the heating function according to the amount of water accumulated in the toilet Q, which not only ensures that the accumulated water on the surface of the toilet seat 1 is dried, saves energy, and the toilet seat 1 is not easy to breed water stains and bacteria, but also automatically stops heating after drying. The user does not need to perform unnecessary operations, and the user does not need to judge whether the accumulated water on the toilet seat 1 needs to be dried, providing the user with a more intelligent and convenient user experience.

[0035] After S1, enter S1-1 to determine whether the distance L between the user's buttocks and the back of the toilet seat 1 reaches the set distance value L0 when the user is sitting. If so, enter S1-2, if not, standby;

[0036] S1-2. Determine whether the time length T that the user uses the cleaning function reaches the set time length value T0. If so, enter S2, if not, wait.

[0037] When the system recognizes that the user has used the cleaning function, the control method determines whether water will splash onto the toilet seat 1 based on the distance L from the user's buttocks to the back of the toilet seat 1 and the length of time T that the user uses the cleaning function, thereby determining whether the heating function of the toilet seat 1 needs to be turned on.

[0038] Among them, the estimated amount of water Q accumulated on the rear surface of the toilet seat 1 in S2 is calculated based on L and T. The larger L and the larger T are, the larger the amount of water Q is. L is the distance from the user's buttocks to the rear of the toilet seat 1 when the user is sitting. The larger L is, the farther the user's buttocks are from the rear of the toilet seat 1, that is, the larger the gap between the user's buttocks and the toilet seat 1 is, which means that the more water splashes when the user uses the washing function, so the amount of water Q accumulated on the rear surface of the toilet seat 1 is larger. T is the length of time the user uses the washing function. The larger T is, the longer the user uses the washing function, then the larger the amount of water Q splashed onto the rear surface of the toilet seat 1. Therefore, through calculations based on L and T, the amount of water Q accumulated on the rear surface of the toilet seat 1 can be estimated more accurately, thereby more accurately controlling the heating start time T2 of the toilet seat 1, saving energy consumption.

[0039] Among them, Q = a (L-L0) * (T-T0), a ≥ 0, where a is the deviation coefficient. Specifically, Figure 2 As shown, the amount of water Q on the rear surface of the toilet seat 1 can be accurately calculated, thereby accurately controlling the heating start time T2 of the toilet seat 1. By introducing the deviation coefficient a, the calculation of the amount of water Q can be actually adjusted. a can be adjusted according to the characteristics of the toilet seat 1 of different models, the habits of different users, and the use environment. By reasonably adjusting the value of a, the amount of water Q can be better predicted, thereby achieving more accurate self-drying control, so that the self-drying function is more in line with the actual needs of users.

[0040] like Figure 4 As shown, specifically, the distance L from the buttocks of the user to the rear of the toilet seat 1 when the user is sitting is calculated as follows: the total length L of the toilet seat 1 总 Subtract the distance Lt from the user's buttocks to the front of the toilet seat 1 when the user is sitting, that is, L = L 总-Lt, Lt is determined by the sensor signal of the toilet seat surface, for example, a capacitive sensor, a pressure sensitive sensor, etc. can be used to obtain the sensor signal. The set distance value L0 and the set time value T0 are obtained through experiments. The deviation coefficient a is correlated with the toilet seat surface morphology, material, heater power, cleaning intensity, room temperature, air humidity, etc., and is also obtained through experiments and calculations.

[0041] In this embodiment, the total length L of the toilet seat 1 can be taken as 总 The length is 500mm and the width is 470mm. The toilet seat 1 has a streamlined surface and is made of resin. The heater power of the toilet seat 1 is set to 40W. The total water volume used by the washing function is Q 总 =600cc, L0=100mm, T0=30s, deviation coefficient a=0.001, the distance from the user's buttocks to the front of the toilet seat 1 when the user is sitting is Lt=300mm, the length of time the user uses the cleaning function is T=60s, the above calculation results in the amount of accumulated water Q=0.001*((500-300)-100)*(60-30)=3ml, and then the activation time T2 of the toilet seat 1 heating function is calculated based on the amount of accumulated water Q=3ml. T2 can be calculated based on the energy conversion formula. The activation time T2 of the toilet seat 1 heating function is controlled by the toilet seat heater. Specifically, taking the room temperature of 20℃, the air humidity of 60%, the energy conversion rate of 50%, and the direct heater control as an example: the activation time T2 of the toilet seat 1 heating function = the energy required for drying / (50%*toilet seat 1 heater power)=(3*10 -6 *3.6*10 7 ) / 0.5 / 40=5.4s, so the opening time T2 of the toilet seat 1 heating function is 5.4s. Among them, the vaporization heat of water is 3.6*10 7 J / kg.

[0042] In another embodiment, if the washing function has gears of different intensities, Q is calculated in association with the gear intensity of the washing function, and Q is proportional to the gear intensity of the washing function. If the user selects a higher intensity washing gear, it may increase the duration of the washing function, increase the water pressure, etc., which will cause the total water volume Q used by the washing function to be 总 Increase, thus affecting the amount of water Q on the surface of toilet seat 1 增 More, Q is associated with the gear intensity of the washing function to calculate, so that the heating time can be accurately adjusted to ensure that the toilet seat 1 is fully dried, while reducing power consumption, providing users with a more intelligent and convenient experience. Figure 3As shown, when 0<Q<Q1, the heating function of the toilet seat 1 is turned on for T2=t1; when Q1<Q<Q2, the heating function of the toilet seat 1 is turned on for T2=t2; when Q2<Q<Q3, the heating function of the toilet seat 1 is turned on for T2=t3; when Qn-1<Q<Qn, the heating function of the toilet seat 1 is turned on for T2=tn, and so on, n=1, 2, 3…

[0043] In another embodiment, after S2, the process proceeds to S3 and the toilet lid is closed. In the S2 stage, the rear surface of the toilet seat 1 is dried, and after the user enters the S3 stage and closes the toilet lid, the interior of the toilet seat 1 can be kept relatively dry, reducing the possibility of bacterial growth, thereby improving the hygiene inside the toilet lid and the health of the user.

[0044] Embodiment 2:

[0045] Among them, the amount of water Q accumulated on the rear surface of the toilet seat 1 is estimated in S2 according to the total amount of water used by the washing function Q 总 And the amount of water added to the toilet Q 增 To calculate the total amount of water used by the cleaning function, Q 总 The flow meter on the toilet lid is used to obtain the water volume before the flushing function is used. The water volume after the flushing function is used is V0, and the water volume after the flushing function is used is V1. 增 =V1-V0, Q=Q 总 -Q 增 Specifically, the water surface area S0 of the toilet before the use of the cleaning function and the water surface area S1 of the toilet after the use of the cleaning function can be obtained through the shooting equipment carried by the health device. Further, the water volume of the toilet before the use of the cleaning function is V0 and the water volume of the toilet after the use of the cleaning function is V1. The difference between V1 and V0 can be used to obtain the increased water volume Q of the toilet. 增 . Use a flow meter to obtain the total amount of water used by the cleaning function Q 总 The flow meter can accurately measure the amount of water used by the flushing function, rather than estimating or based on a fixed value, so it can more accurately predict the amount of water accumulated on the rear surface of the toilet seat 1 Q, by monitoring the difference in the amount of water in the toilet before and after the flushing function is used, that is, the amount of water added to the toilet Q 增 , the amount of water Q splashed onto the surface of the toilet seat 1 can be indirectly obtained, and a more accurate calculation of the amount of water Q can be achieved, thereby obtaining an accurate heating on time T2.

[0046] Among them, the amount of water Q estimated on the rear surface of the toilet seat 1 in S2 takes into account the amount of residual water inside the toilet and on the user's body surface. Specifically, the effect of subtracting the amount of residual water inside the toilet and on the user's body surface is relatively fixed and can be regarded as a constant. By subtracting the amount of residual water inside the toilet and on the user's body surface, the self-drying control is more intelligent and accurate, and the user does not need to worry about the problem of residual water stains, which improves the comfort and convenience of use, and can avoid unnecessary drying time. In this way, the toilet seat 1 does not require additional heating and drying, which saves energy consumption, ensures that the toilet seat 1 is fully dried, prevents water from remaining on the surface of the toilet seat 1, reduces the possibility of bacteria and other microorganisms, and improves the hygiene of the toilet seat 1.

[0047] For example Figure 5 As shown, in this embodiment, the total amount of water used by the washing function is Q 总 The flow meter on the toilet seat is used to provide real-time feedback of the value. When the value is stable, the flow rate is calculated using the average value. When the flow rate is unstable, the integral calculation is used. In this embodiment, the total water volume Q used for the washing function can be used. 总 The average value is calculated, that is: Q 总 =600ml / min, Q 增 The water level can be calculated by the water level sensor, and the actual volume can be obtained from the relationship between the water level and the volume of the toilet. The water level before the flushing function is used is 10 cm, which corresponds to a volume of 150 ml for the toilet cavity, that is, the water volume before the flushing function is used is V0 = 150 ml. After the flushing function is used, the water level is 15 cm, which corresponds to a volume of 700 ml for the toilet cavity, that is, the water volume before the flushing function is used is V1 = 700 ml. Q can be obtained by calculation. 增 =V1-V0=700-150=550ml. The residual water volume inside the toilet and on the user's body surface can be regarded as a constant. It is obtained through experiments. Specifically, the average value of more than 30 human body simulation experience data is taken, and 10ml is taken. The length of time the user uses the washing function is T=60s. Through the above parameters, it can be calculated that Q=Q 总 -Q 增 -10 = 600-550-10 = 40 ml. Then, the toilet seat heating is controlled according to the law of conservation of energy and the characteristics of the toilet seat heater.

[0048] For other contents not described in this embodiment, reference may be made to the above embodiments.

[0049] Embodiment three:

[0050] The amount of water Q accumulated on the rear surface of the toilet seat 1 can also be obtained by other means. In one embodiment, the amount of water Q accumulated on the rear surface of the toilet seat 1 in S2 is estimated by calculating the number and frequency of water droplets splashing onto the rear surface of the toilet. By monitoring the number and frequency of water droplets splashing onto the rear surface of the toilet, the amount of water Q accumulated on the rear of the toilet seat 1 can be accurately obtained, and the heating on time T2 can be more accurately controlled.

[0051] The number and frequency of water droplets are obtained by detecting the deformation data of the rear surface of the toilet through the pressure sensor. The pressure sensor can accurately sense tiny deformations, thereby capturing and measuring the landing of water droplets in real time, accurately measuring the number and frequency of water droplets, and the pressure sensor can sense deformation data in real time, so it can quickly respond to user behavior, calculate the amount of accumulated water Q in time, and start the self-drying function, so that it can be quickly dried after the user finishes using it, improving the efficiency of self-drying.

[0052] Specifically, a pressure sensor is provided on the toilet seat 1, and the minimum detectable area of ​​the pressure sensor is M. The AD value of the pressure sensor is used to determine whether there are water drops. For example, the minimum detectable area of ​​the pressure sensor is 1mm 2 If the AD value of the pressure sensor is greater than 100, it is determined that there are water droplets. The area with AD value greater than 100 is accumulated to obtain the volume of all water droplets.

[0053] The AD value of the pressure sensor represents the digitized result of the analog voltage signal measured by the pressure sensor. First, the pressure change on the toilet seat 1 is measured to generate an analog voltage signal whose amplitude is related to the pressure. The analog voltage signal may need to be amplified, filtered, or otherwise processed to ensure that the analog voltage signal within the effective range can be correctly read by the analog-to-digital converter, which converts it into digital form and generates an AD value. This AD value is usually an integer, representing a discrete approximate value of the voltage.

Specifically, the toilet generally includes a toilet seat and a toilet, the toilet seat includes a toilet seat body and a toilet seat 1, the toilet seat body is installed on the rear side of the top of the toilet and is provided with a cleaning component, the toilet seat 1 is installed on the toilet seat body and is provided with a heating device, and a controller extending forward may be provided on one side of the toilet seat body, and corresponding function selection buttons may be set on the controller, for example, after the user selects the cleaning function after use, the controller can control the cleaning component to realize the cleaning function, and then control the operation by the control method of self-drying toilet seat in the above embodiment. The controller can also use a remote controller separated from the toilet seat body.

[0057] In addition to the above-mentioned preferred embodiments, the present invention also has other implementation modes.
