Description

Technical Field

[0001] This invention relates to the field of control technology, and in particular to a self-cleaning control method for a toilet seat, a toilet seat, and a toilet. Background Technology

[0002] Because the heated seat of a self-cleaning toilet is movable, it rotates 360° in self-cleaning mode. Therefore, the heated seat can only be powered by contact power supply or wireless power transmission.

[0003] Wireless power transmission methods suffer from high costs and large size, limiting their applicability. For contact-based power supply, the seat needs to rotate to accommodate different user postures such as sitting and cleaning. Repeated insertion and removal of the power contacts can lead to unstable contact impedance, momentary disconnection, or poor contact. Furthermore, many products activate high-power heating after contact insertion or before fully confirming contact reliability, causing arcing between contacts, resulting in contact erosion and welding. Simultaneously, surge currents impact the downstream power module, triggering MCU (Micro Control Unit) resets, capacitor damage, and other malfunctions. Actual failure rates are high, significantly increasing maintenance costs. Summary of the Invention

[0009] Further, obtaining the impedance value between the first contact and the second contact includes: The impedance value between the first contact and the second contact is determined based on the formula UAD=(R0 / (R0+R1))×VCCMCU, where R0 is the impedance value, R1 is the resistance value between the first contact and the first power supply, VCCMCU is the voltage value of the first power supply MCU_VCC, and UAD is the voltage sample value between the first contact and the second contact.

[0010] Furthermore, the method also includes: if the determination result is that the impedance value is not within the normal range, then an alarm is issued.

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0019] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this invention are used to distinguish different objects, not to limit a specific order. The various embodiments of this invention described below can be performed individually or in combination with each other; the embodiments of this invention do not impose specific limitations in this regard.

[0020] Figure 1 This is an exploded view of the structure of a toilet provided in an embodiment of the present invention. Figure 2 This is a schematic diagram of the seat and main body provided in an embodiment of the present invention. Figure 3 This is an exploded view of the seat structure provided in an embodiment of the present invention. Figure 4 This is an exploded view of the main body and the seat provided in an embodiment of the present invention. Figure 5 This is an external view of a toilet provided in an embodiment of the present invention.

[0021] like Figures 1-4 As shown, the toilet includes a toilet body 20, a toilet seat 10, and an electronic device 50 disposed on the toilet body 20 for controlling the operation of the heating module 13; the toilet seat 10 includes a main body 11 pivotally connected to the toilet body 20, a seat 12 rotatably supported on the main body 11, and a heating module 13 disposed for heating the seat 12. Figure 1-3 (No schematic diagram shown in the figure). The seat 12 is equipped with a position triggering component. The main body 11 is used to support the seat 12 to flip up and down relative to the toilet body 20. The seat 12 rotates relative to the main body 11 around the toilet seat 10's drain hole 30. The main body 11 is equipped with a position feedback component that is electrically connected to the toilet seat self-cleaning control device. The position feedback component is used to provide position information of the position triggering component. The position information is used to represent the position of the seat 12 relative to the main body 11.

[0022] Specifically, such as Figure 3 As shown, the seat 12 includes a seat surface 121 and a rotating seat ring 122. The heating module 13 includes a seat ring heating element 131, which is disposed between the seat surface 121 and the rotating seat ring 122. After the user finishes using the toilet, the cleaning unit 40 moves to the cleaning position. At the same time, the rotating seat ring 122 and the cleaning unit 40 move relative to each other, causing the seat surface 121 of the seat 12 to rotate 360° relative to the main body 11 around the toilet hole 30. The cleaning unit 40 sprays and cleans the entire seat surface 121, thereby reducing dirt on the seat surface 121. This allows the next user to use the toilet directly without having to clean the seat surface 121, improving the user experience. Furthermore, after the seat surface 121 is cleaned, the cleaning unit 40 can move to a clearance position so that the seat surface 121 is not obstructed, allowing the user to sit normally on the seat surface 121 of the seat 12 and ensuring that the user can use the toilet normally.

[0023] This invention provides a method for controlling the self-cleaning of a toilet seat, which specifically includes: The heating state of the heating module 13 is controlled based on heating commands and location information.

[0024] Specifically, when the position feedback component determines that the position of the seat 12 relative to the main body 11 has been returned to its original position based on the position information of the position triggering component, it indicates that the seat 12 has returned to the position corresponding to the main body 11 after being cleaned by rotation and is in good contact. At this time, the electronic device 50 will generate a heating command and control the heating module 13 to supply power to heat the seat 12 based on the heating command.

[0025] In this embodiment of the invention, the position of the seat 12 and the main body 11 is determined by the position information of the position triggering component fed back by the position feedback component. Then, a heating command is generated based on the determined positional relationship, and the heating module 13 is controlled to supply power to heat the seat 12 based on the heating command. This solves the technical problem in the prior art that the seat 12 of the self-cleaning toilet is prone to contact abnormalities when it is powered after rotating relative to the main body 11, which leads to product damage, high measured failure rate and high maintenance cost. It achieves the technical effect of safely supplying power to heat the seat without increasing cost and complexity, improving equipment reliability and enhancing user experience.

[0026] Optionally, the position triggering component and the position feedback component are mutually cooperating components. The position feedback component is a Hall sensor and the position triggering component is a magnet; or, the position feedback component is a photoelectric sensor and the position triggering component is a transmitter; or, the position feedback component is a first electrode and the position triggering component is a second electrode, and the first electrode and the second electrode are electrically connected; the heating module 13 includes a heating control device 132 and a power supply unit 133. The heating state of the heating module 13 is controlled based on heating commands and position information, including: In response to the determination that the positions of the position triggering component and the position feedback component correspond based on the position information, a heating command is generated; based on the heating command, the power supply unit 133 is controlled by the heating control device 132 to supply power and heat the seat.

[0027] Specifically, a position feedback component is disposed on the main body 11, and a position triggering component that cooperates with the position feedback component is disposed on the seat 12 and can rotate with the seat 12. The position feedback component and the position triggering component can be configured as a Hall sensor and a magnet, or as a photoelectric sensor and a transmitter, or as an electrically connected first electrode and a second electrode, as needed. When the position feedback component detects the position triggering component, it indicates that the seat 12 has returned to its original position and corresponds with the main body 11. The electronic device 50 then generates a heating command and controls the heating module 13 to supply power to heat the seat 12 based on the heating command.

[0028] Figure 6 This is a circuit diagram illustrating the operation of the heating module provided in an embodiment of the present invention. Figure 7 This is a schematic diagram of the conduction of conductive sheet A and conductive sheet B provided in an embodiment of the present invention. Figure 8 This is a schematic diagram of the motion state of the seat rotation provided in an embodiment of the present invention.

[0029] For example, such as Figure 4 As shown, a rotating motor is provided between the base plate and the main body 11, and the rotating motor can drive the motion gear set 1220 in the rotating seat ring 122 to rotate.

[0030] See Figure 4 , Figures 6-8 Taking a position feedback component and a position trigger component as a Hall sensor and a magnet, and an electronic device 50 installed on the toilet seat as an example, when the control unit (the toilet's own controller) receives a seat rotation command, the control unit first disconnects the power supply to the conductive sheet A (i.e., the first contact point), and the seat heating stops; then, the control unit controls the rotating motor to drive the motion gear set 1220 to rotate the seat part 12, including the conductive sheet B (the first conductive sheet corresponding to the first contact point); at this time, the conductive sheets A and B disengage, as... Figure 8 As shown; when the Hall sensor detects that the seat ring has rotated to a preset number of revolutions, the seat 12 stops rotating, and the conductive plates A / B are connected, as shown. Figure 7 As shown, the heating control device 132 controls the power supply unit 133 to supply power to the conductive sheet A, so that the seat ring heating sheet 131 starts to heat the seat part 12 after being energized, realizing the seat ring rotation heating control process.

[0031] In this embodiment of the invention, the magnet moves synchronously with the seat 12. When the magnet approaches the Hall sensor, the Hall sensor outputs an electrical signal. By counting the number of electrical signal pulses per unit time, the number of rotations of the seat 12 can be calculated, thereby determining the positional correspondence between the seat 12 and the main body 11. This non-contact detection method avoids mechanical wear and improves the stability and service life of the detection.

[0032] Figure 9 This is a structural diagram of the heating module provided in an embodiment of the present invention.

[0033] Optionally, such as Figure 9 The heating control device 132 includes an impedance detection unit 51. The impedance detection unit 51 includes a first contact 510 disposed on the seat 12 and a first conductive sheet (not shown in the figure) disposed on the main body 11 corresponding to the first contact 510. It also includes a second contact 511 disposed on the seat 12 and a second conductive sheet (not shown in the figure) disposed on the main body 11 corresponding to the second contact 511. In response to determining that the positions of the position triggering component and the position feedback component correspond based on the position information, the heating command is generated by: obtaining the impedance value between the first contact 510 and the second contact 511 in response to determining that the positions of the position triggering component and the position feedback component correspond based on the position information; and generating the heating command in response to determining that the impedance value is within the normal range.

[0034] Optionally, the method also includes: if the judgment result is that the impedance value is not within the normal range, then an alarm is issued.

[0035] Specifically, if the seat 12 has returned to its original position, the heating control device 132 acquires the impedance value between the first contact 510 and the second contact 511, and determines whether the impedance value is within the normal range. Only if the impedance value is within the normal range does it indicate that the first contact 510 and the second contact 511 are in good contact with their respective conductive sheets, thereby executing the subsequent generation of heating commands and controlling the heating module 13 to supply power and heat the seat 12 according to the heating commands. Otherwise, it indicates that the first contact 510 and the second contact 511 are in poor contact with their respective conductive sheets. To avoid unnecessary damage, an alarm is issued so that the user can confirm the cause of the fault as soon as possible and avoid greater losses.

[0036] Optionally, such as Figure 9 As shown, the heating control device 132 also includes a first switching unit KM1 and a second switching unit KM2. The first contact 510 is electrically connected to the positive terminal of the power supply unit 133VCC1 through the first switching unit KM1, and the second contact 511 is electrically connected to the negative terminal of the power supply unit 133VCC1 through the second switching unit KM2. Figure 9 (In the middle, ground is represented by GND) connection; The heating control device 132 controls the power supply unit 133VCC1 to supply power to the seat 12 for heating based on the heating command, including: Based on the heating command, the first switching unit KM1 and the second switching unit KM2 are controlled to operate so that the power supply unit 133VCC1 supplies power to the seat 12 for heating through the first contact 510 and the second contact 511.

[0037] Specifically, if the impedance value between the first contact 510 and the second contact 511 is within the normal range, the heating control device 132 controls the first switching unit KM1 and the second switching unit KM2 to operate so that the power supply unit 133VCC1 can supply power to the seat 12 for heating through the first contact 510 and the second contact 511, thus completing the heating command.

[0038] In this embodiment of the invention, the impedance value between two contacts is detected to determine whether the two contacts are in good contact. Only after confirming good contact is the high-power heating power supply turned on. This solves the technical problem in the prior art where abnormal contact easily occurs when the seat of a self-cleaning toilet is powered after rotating relative to the main body, which leads to product damage, high measured failure rate, and high maintenance cost. It achieves the technical effect of safely powering and heating the seat without increasing cost and complexity, thereby improving equipment reliability and enhancing user experience.

[0039] Optionally, such as Figure 9 As shown, the heating control device 132 also includes a control unit MCU and a sampling unit 52, and the impedance detection unit 51 also includes a filtering unit 512, a voltage divider unit 513 and a first power supply MCU_VCC; The sampling unit 52 and the first power supply MCU_VCC are both electrically connected to the control unit MCU; Voltage divider unit 513 is electrically connected to sampling unit 52 through filter unit 512; The control unit MCU obtains the impedance value R0 between the first contact 510 and the second contact 511 through the sampling unit 52, and controls the first switch unit KM1 and the second switch unit KM2 to operate when the impedance value R0 is within the normal range, so that the power supply unit 133VCC1 supplies power to the seat 12 for heating through the first contact 510 and the second contact 511.

[0040] Specifically, participate in Figure 9 In normal circumstances, the first switching unit KM1 and the second switching unit KM2 are connected to the common terminal 5 and the normally closed terminal 3, so that the first contact 510 and the second contact 511 are electrically connected to the voltage divider unit 513. The signals sent to the voltage divider unit 513 by the first contact 510 and the second contact 511 at this time are AD_P and AD_N, respectively. The signal collected by the sampling unit 52 through the filtering unit 512 is AD Seat, that is, the above-mentioned U AD The equivalent impedance resistance RX is the impedance value R0 between the first contact 510 and the second contact 511. When the detection result shows that the impedance value R0 is within the normal range, the control unit MCU sends a Ctrl1 signal, which turns on the first transistor Q1. The coils of the first switching unit KM1 and the second switching unit KM2 are both energized, the common terminal 5 and the normally open terminal 2 are attracted, the first power supply VCC1 is connected, and the seat 12 is heated through the first contact 20 and the second contact 30.

[0041] Optionally, such as Figure 9 As shown, the voltage divider unit 513 includes a first resistor R1 and an equivalent impedance resistor RX, and the filter unit 512 includes a fifth resistor R5 and a first capacitor C1. The first end of the first resistor R1 is electrically connected to the first power supply MCU_VCC, and the second end of the first resistor R1 is electrically connected to the first contact 510 through the first switching unit KM1. The first end of the equivalent impedance resistor RX is electrically connected to the second end of the first resistor R1. The second end of the equivalent impedance resistor RX is grounded to GND. The second end of the equivalent impedance resistor RX is electrically connected to the second contact 511 through the second switching unit KM2. The first end of the fifth resistor R5 is electrically connected to the sampling unit 52, the second end of the fifth resistor R5 is electrically connected to the second end of the first resistor R1, the first end of the first capacitor C1 is electrically connected to the second end of the fifth resistor R5, and the second end of the first capacitor C1 is grounded to GND.

[0042] Optionally, such as Figure 9As shown, the first switching unit KM1 is a single-pole double-throw relay. The common terminal 5 of the first switching unit KM1 is electrically connected to the first contact 510. The normally closed terminal 3 of the first switching unit KM1 is electrically connected to the voltage divider unit 513. The normally open terminal 2 of the first switching unit KM1 is electrically connected to the power supply unit 133VCC1. The coil of the first switching unit KM1 (i.e., between connectors 1 and 4) is connected between the second power supply VCC2 and the collector of the first transistor Q1. The second switching unit KM2 is a single-pole double-throw relay. The common terminal 5 of the second switching unit KM2 is electrically connected to the second contact 511. The normally closed terminal 3 of the second switching unit KM2 is electrically connected to the voltage divider unit 513. The normally open terminal 2 of the second switching unit KM2 is grounded to GND. The coil of the second switching unit KM2 (i.e., between connectors 1 and 4) is connected between the second power supply VCC2 and the collector of the first transistor Q1.

[0043] Optionally, such as Figure 9 As shown, the heating control device 132 also includes a switch triggering unit 53, which includes a first transistor Q1, a second resistor R2 and a third resistor R3. The first end of the second resistor R2 is electrically connected to the control unit MCU, the second end of the second resistor R2 is electrically connected to the base of the first transistor Q1, the third resistor R3 is connected in parallel between the base and emitter of the first transistor Q1, and the emitter of the first transistor Q1 is grounded to GND.

[0044] Optionally, the heating control device 132 also includes an alarm unit (not shown in the figure); the alarm unit is electrically connected to the control unit MCU.

[0045] Based on the above technical solutions, obtaining the impedance value between the first contact 510 and the second contact 511 specifically includes: Based on formula U AD =(R0 / (R0+R1))×VCC MCU Determine the impedance value between the first contact and the second contact, where R0 is the impedance value, R1 is the resistance value between the first contact 510 and the first power supply MCU_VCC, and VCC is the resistance value between them. MCU U is the voltage value of the first power supply MCU_VCC. AD This is the voltage sample value between the first contact 510 and the second contact 511.

[0046] Specifically, see Figure 6 The impedance value R0 between the first contact 510 and the second contact 511 can be obtained using the formula U. AD =(R0 / (R0+R1))×VCC MCUThe calculated first power supply MCU_VCC is typically a small voltage, such as 3.3V or 5V, used to detect the impedance value R0 between the first contact 510 and the second contact 511. This prevents further damage caused by directly applying a large voltage if at least one of the first contact 510 or the second contact 511 has poor contact. After calculating the impedance value R0, it is compared with a set impedance range to determine whether the impedance value R0 is within the normal range.

[0047] For example, taking the first power supply MCU_VCC as 3.3V as an example, R1 = 200Ω is set. For the impedance value R0, there are three cases: (1) when the contacts are in good contact, R0 is approximately 15Ω; (2) when any contact is contaminated or has poor contact, R0 is 30Ω-100Ω; (3) when the contacts are disconnected or internal components are damaged, R0 is infinite. The U values ​​corresponding to the above three cases are... AD The values ​​are 0.23V, 0.43-1.1V, and 3.3V, respectively.

[0048] It can be seen that U in the three cases AD The voltage difference is significant, and the heating control device 132MCU can easily determine the current contact status of the contacts. Clearly, only when U... AD The contact is considered to be in good contact only when the voltage is around 0.23V. At this point, the high-voltage (usually 24V) power supply unit 133VCC1 is turned on to supply power for heating.

[0049] Based on the above technical solutions, before controlling the heating state of the heating module 13 based on heating commands and position information, the method further includes: Determine if the toilet seat has activated its self-cleaning program; if so, execute the self-cleaning program; otherwise, determine if the self-cleaning toilet has received a heating command from the toilet seat.

[0050] Specifically, after the toilet seat is initialized, the heating control device 132NCU first checks whether the cleaning button is pressed, that is, whether the self-cleaning program has been started. If the cleaning button is pressed, the toilet seat directly executes the seat cleaning program. If the button is not pressed, it jumps to the seat heating subroutine based on the received heating command, that is, it further determines whether power supply heating can continue based on the impedance value R0 between the first contact 510 and the second contact 511.

[0051] In this embodiment of the invention, a two-step power supply method—first detecting low voltage and then conducting high power—solves the problem of contact arcing, significantly improving contact lifespan. Furthermore, by setting up periodic proactive health monitoring, power is immediately cut off and reported upon detecting abnormalities, preventing impact on the power supply unit 133. Simultaneously, the design of this embodiment of the invention possesses platform versatility, supporting multi-voltage and threshold adaptation, and can be reused in rotating power supply scenarios as needed. Multiple protections such as power-on self-test, watchdog timer, and signal debouncing can also be set as needed, along with continuous heating protection without sensor lag and fault prompts for rapid recovery. Compared to the traditional power-on-then-detection scheme, this completely eliminates arcing and surges, significantly improving MTBF (Mean Time Between Failure) and greatly reducing after-sales failures, achieving a generational breakthrough from post-repair maintenance to pre-prevention with minimal cost.
