Technical Field
[0001] This application relates to, but is not limited to, the field of bathroom facilities, and in particular to a smart toilet and its control method, control device, and control method for electronic devices. Background Technology
[0002] With the development of technology, smart toilets have become increasingly common in people's lives. Currently, smart toilets are mainly controlled by remote control or by control buttons on the toilet itself. However, these methods require users to directly touch the remote control or press the control buttons on the toilet, and since these buttons are rarely cleaned, they can easily lead to bacterial growth and affect the user's health.
[0003] Some smart toilets also feature foot-controlled switches, but these switches can only perform simple actions like opening and closing the lid, and cannot perform complex functions such as washing or flushing, thus failing to meet users' diverse operational needs. Other smart toilets use laser-projected control patterns and employ an "infrared sensor + camera" approach to recognize user gestures. While this method improves hygiene, installing cameras on smart toilets raises privacy concerns, and the installation of infrared sensors requires drilling holes in the toilet bowl, detracting from the toilet's aesthetics. Summary of the Invention

[0026] Determine whether the number of limbs in the projection area is within a set range and whether the user's limbs are performing effective operations within the projection area;
[0027] If the number of limbs in the projection area is not within the set number range or the user's limbs do not perform effective operations in the projection area, it is determined that the user has performed an invalid operation on the control pattern.
[0028] Based on the number of limbs in the projection area being within the set range and the user's limbs performing effective operations within the projection area, it is determined that the user has performed effective operations on the control pattern.

[0032] Based on the fact that the user's limbs fall within the valid operation area of the control pattern and the user's limbs' operation on the control pattern is a valid action, it is determined that the user's limbs are performing a valid operation within the projection area.

[0043] A click is considered valid if the user's limb remains on the control pattern for a duration greater than or equal to t1 and less than or equal to t2.
[0044] If the time a user's limb stays on the control pattern is less than t1 or greater than t2, the click action is considered invalid.
[0045] In one exemplary embodiment, 0.5s ≤ t1 < t2 ≤ 5s.

[0051] A valid sliding action is determined based on the user's limbs remaining on the control pattern for a set period of time and then sliding in a set direction after the set period of time.
[0052] If the user's limb stays on the control pattern for a period of time exceeding the set range, or if the user does not slide in the set direction after the stay, the sliding action is judged as invalid.
[0053] This application also provides a control device, which includes a processor, a memory, and a computer program stored in the memory and executable on the processor. When the computer program is executed by the processor, it implements the steps of the aforementioned control method.

[0080] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be arbitrarily combined with each other.
[0081] This application provides a control method for a smart toilet, such as... Figures 1 to 3 As shown, the control method includes: determining whether the user has performed a valid operation on the control pattern in the projection area using millimeter waves; and controlling the smart toilet to perform the corresponding action based on the user's valid operation on the control pattern.
[0082] The control pattern within the projection area can be formed either by laser projection using a laser projector or by displaying a pre-pasted drawing on the ground.
[0083] Millimeter waves are used to determine whether the user has effectively operated the control pattern. When the user lifts their foot to operate the control pattern, millimeter waves are used to recognize the user's action to determine whether the user has effectively operated the control pattern, so as to provide a basis for the smart toilet to perform corresponding operations.
[0084] Based on a valid user interaction with the control pattern, the smart toilet will perform corresponding actions, such as washing, drying, or opening the lid. Conversely, if the user does not interact with the control pattern, the smart toilet will remain in its current state and will not perform any actions.
[0085] Distinguishing between valid and invalid user actions on the control panel helps prevent accidental triggering and malfunctions of the smart toilet, thus improving the user experience.
[0086] In an exemplary embodiment, the control method for a smart toilet further includes: determining whether a user wants to use the smart toilet; and after determining that the user wants to use the smart toilet, performing a step of determining whether the user has effectively operated the control pattern in the projection area via millimeter waves.
[0087] Before using millimeter waves to determine whether a user is effectively operating the control pattern in the projection area, it first determines whether the user intends to use the smart toilet. This prevents the smart toilet from being accidentally triggered when the user has no intention of using it, thus improving the reliability of the smart toilet.
[0088] Before using millimeter waves to determine whether a user has effectively operated the control pattern in the projection area, it is first determined whether the user needs to use the smart toilet. This can also prevent the smart toilet from being repeatedly triggered and reduce wear and tear on the smart toilet.
[0089] In one exemplary embodiment, such as Figure 2 As shown, determining whether a user wants to use the smart toilet includes: determining whether the user is within a set range of the smart toilet; and determining whether the user wants to use the smart toilet based on the user being within the set range of the smart toilet.
[0090] If the user is within a set distance of the smart toilet, it is determined that the user needs to use the smart toilet; if the user is outside the set distance of the smart toilet, it is determined that the user does not need to use the smart toilet.
[0091] By determining the distance between the user and the smart toilet, the system can identify when the user needs to use the smart toilet. The control logic is simple and easy to implement, which can effectively reduce the frequency of the smart toilet being accidentally triggered.
[0092] In practical applications, when a user wants to use the smart toilet, they walk towards it. Once the smart toilet detects that the user has entered its designated recognition range, it determines that the user needs to use the smart toilet. Furthermore, this distance-based recognition method allows control patterns to be projected in advance before the user even reaches the smart toilet, avoiding waiting and eliminating the need for any user intervention. This high degree of automation improves user satisfaction.
[0093] It should be understood that, in addition to determining whether a user needs to use the smart toilet based on the distance between the user and the smart toilet, other methods can be used for supplementary determination, such as: determining whether a user wants to use the smart toilet by pre-setting and recognizing the user's waving gesture, or the user sending a message to the smart toilet via their smartphone indicating that they want to use the smart toilet.
[0094] In an exemplary embodiment, the control pattern includes a first type of control pattern and a second type of control pattern; such as Figure 2 As shown, between the step of determining whether the user wants to use the smart toilet and the step of determining whether the user has effectively operated the control pattern in the projection area via millimeter waves, the control method further includes: determining whether the user is in a seated state; projecting the control pattern into the projection area, including: projecting a first type of control pattern based on the user being in a seated state; and projecting a second type of control pattern based on the user not being seated.
[0095] The control patterns include a first type and a second type to accommodate different user needs at different stages of using the smart toilet, such as:
[0096] When the user is seated, a first type of control pattern is projected; the first type of control pattern may include at least one of the following: posterior wash icon, automatic cleaning icon, feminine wash icon, drying icon, standby icon, water temperature icon, and air temperature icon; that is, when the user is seated, the first type of control pattern can be operated to realize functions such as posterior wash, automatic cleaning, feminine wash, drying, standby, adjusting water temperature, and adjusting air temperature.
[0097] When the user is not seated, a second type of control pattern is projected; the second type of control pattern includes at least one of the following: a flip cover icon, a flip circle icon, and a flush icon; that is, when the user is not seated, the second type of control pattern can be operated to realize functions such as flipping the cover, flipping the circle, and flushing.
[0098] It should be understood that for the user's unseatened state, including before using the smart toilet and after using it, the same second-type control pattern (i.e., including the lid-opening icon, the flip-around icon, and the flush icon) can be used for both states in practical applications to simplify the control logic. Alternatively, different control patterns can be projected based on the user's unseatened state before and after use; for example, the lid-opening icon and the flip-around icon could be projected before use, while the flush icon could be projected after use.
[0099] In one exemplary embodiment, the first type of control pattern further includes a first switching icon, and the other icons of the first type of control pattern are configured to be displayed in multiple pages for switching purposes. The first switching icon is configured to switch the display page of the first type of control pattern. The second type of control pattern further includes a second switching icon, and the other icons of the second type of control pattern are configured to be displayed in multiple pages for switching purposes. The second switching icon is configured to switch the display page of the second type of control pattern.
[0100] When there are many icons in the first type of control pattern, displaying all the icons simultaneously will occupy a large space in the projection area, and the large projection area is also not conducive to the user lifting their foot to operate. By displaying the icons in the first type of control pattern in pages and switching them, only some icons are displayed at the same time. When the function icon that the user needs is not displayed, the user can use the first switching icon to obtain other function icons, ensuring convenient and quick operation for the user.
[0101] The second type of control pattern is similar to the first type of control pattern, and will not be described in detail here.
[0102] In one exemplary embodiment, determining whether a user is within a set distance range from the smart toilet includes: determining whether the user is within a set distance range from the smart toilet via millimeter waves.
[0103] The smart toilet uses millimeter waves to determine whether the user is within a set range, providing a basis for subsequent actions. This millimeter-wave detection ensures high accuracy and avoids the drawback of traditional infrared sensors requiring holes in the toilet bowl.
[0104] The smart toilet detects whether the user is sitting down using a seat sensor (such as a pressure sensor).
[0105] In one exemplary embodiment, such as Figure 1 and Figure 3 As shown, between the step of determining that the user is seated and the step of determining whether the user has effectively operated the control pattern in the projection area via millimeter waves, the control method further includes: projecting the control pattern into the projection area.
[0106] The control pattern is projected onto the projection area. The floor in front of the smart toilet serves as the projection area, where the control pattern is projected so that the user can operate it effectively by using their feet.
[0107] It should be understood that the projection area can also be located on the floor to the left or right of the smart toilet; in addition, the projection area can also be located on the wall so that the user can operate it with their feet or hands.
[0108] In addition to using a laser projector for laser projection, control patterns can also be displayed to users by pre-attaching stickers with control patterns on the ground. In other words, the step of projecting control patterns onto the projection area with a laser projector can be omitted as needed.
[0109] When using stickers with control patterns on the floor, the number of control patterns can be set to a small number (e.g., 4) to avoid inconvenience for users due to too many patterns. For example, the projection area can be divided into a seated control area and an exit control area. The exit control area includes two control patterns: "Lid Flip" and "Flush," while the seated control area includes two control patterns: "Auto / Stop" and "Flush." When the user is seated, both feet are in the exit control area closest to the toilet body (i.e., both feet are on the "Lid Flip" and "Flush" buttons respectively). Only when either foot leaves the exit control area, the user clicks a control pattern in the seated control area, and then returns to the exit control area, and the entire action is completed within 3 seconds, is it considered that the user has triggered a control pattern in the seated control area.
[0110] For example, if a user is seated with their left foot in the "rinsing" position, and then lifts their left foot away from the "rinsing" position, clicks "Auto / Stop" with their left foot, and then returns to the "rinsing" position, this is considered a foot-controlled activation of "Auto / Stop," triggering a preset function such as automatic washing. Similarly, if a user is leaving their seat with both feet in the seating control area, and their left foot moves from "Auto / Stop" to "rinsing" and then back to "Auto / Stop," this triggers the "rinsing" function. This method effectively avoids accidental triggering.
[0111] It should be understood that, in addition to using millimeter waves to determine whether a user is within the set range of the smart toilet, other methods can also be used for identification, such as using infrared sensors to determine whether a user is within the set range of the smart toilet.
[0112] In one exemplary embodiment, such as Figure 3 As shown, determining whether a user has performed a valid operation on a control pattern using millimeter waves includes: identifying the number of limbs the user enters the projection area and the user's limb movements within the projection area using millimeter waves; determining whether the number of limbs in the projection area is within a set range and whether the user's limbs have performed a valid operation within the projection area; determining that the user has performed an invalid operation on the control pattern if the number of limbs in the projection area is not within the set range or the user's limbs have not performed a valid operation within the projection area; and determining that the user has performed a valid operation on the control pattern if the number of limbs in the projection area is within the set range and the user's limbs have performed a valid operation within the projection area.
[0113] Millimeter-wave scanning is used to identify the number of user limbs entering the projection area and the user's limb movements within the projection area; it determines whether the number of limbs in the projection area is within a set range and whether the user's limbs are performing valid operations within the projection area. During the identification of user actions on control patterns, accurate identification is required to eliminate interference from accidental touches (such as randomly lifting a foot). Valid user actions are accurately identified by setting conditions.
[0114] Specifically, this can be achieved by recognizing the number of limbs a user enters within the projection area and the user's actions within the projection area. For example, if a user enters the projection area with one foot and completes an action within that foot, it is considered a valid operation of the control pattern. Conversely, if a user enters the projection area with both feet simultaneously, it is considered an invalid operation. Alternatively, if a user enters the projection area with one foot but does not complete an action within the projection area, it is considered an invalid operation.
[0115] By setting two preset restrictions, namely "the number of limbs entering the projection area" and "the effective operation of the user's limbs in the projection area," the system can effectively eliminate irrelevant user actions from interfering with the smart toilet and prevent it from being accidentally triggered.
[0116] In one exemplary embodiment, such as Figure 2 As shown, determining whether a user's limbs are performing a valid operation within the projection area includes: determining whether the user's limbs fall within the valid operation area of the control pattern using millimeter waves; determining whether the user's limbs' operation on the control pattern is a valid action using millimeter waves; and determining that the user's limbs are performing a valid operation within the projection area based on the fact that the user's limbs fall within the valid operation area of the control pattern and that the user's limbs' operation on the control pattern is a valid action.
[0117] The system determines whether a user is performing a valid operation within the projection area by specifying that "the limb is located within the valid operation area" and "the operation is a valid operation".
[0118] Specifically, when a user's limb falls within the effective operating area of the control panel, and the user's action on the control pattern is a valid action, it is determined that the user's limb has performed a valid operation within the projection area. Then, based on the valid operation performed by the user on the control pattern, the smart toilet is controlled to execute the corresponding action.
[0119] In an exemplary embodiment, determining whether a user's limb falls within the effective operating area of a control pattern using millimeter waves includes: acquiring the position of the user's limb entering the projection area using millimeter waves, comparing it with the position of the control pattern, and determining whether the user's limb falls within the effective operating area of the control pattern based on the comparison result.
[0120] Millimeter waves can be used to detect whether someone is near the smart toilet to determine if the user wants to use it, and can also detect whether the user's limbs are within the valid operating area and whether the action is valid.
[0121] In other words, a user's limbs are considered to have performed a valid operation within the projection area only if the user's limbs fall within the valid operation area and the user performs a valid action.
[0122] In one exemplary embodiment, such as Figure 3 As shown, the position of the user's limbs within the projection area is obtained using millimeter waves and compared with the position of the control pattern. The comparison result determines whether the user's limbs fall within the effective operating area of the control pattern. This includes: obtaining the coordinate area of the user's limbs and comparing it with the coordinate area of the control pattern. When the overlap between the coordinate area of the user's limbs and the coordinate area of the control pattern is greater than or equal to M, it is determined that the user's limbs fall within the effective operating area of the control pattern.
[0123] In practical use, since the user's limbs may not completely overlap with the effective operating area of the control pattern, when the overlap between the coordinate area of the user's limbs and the coordinate area of the control pattern is greater than or equal to a certain value (M), the user's limbs can be considered to fall within the effective operating area of the control pattern. This avoids the problem of users having difficulty controlling the toilet's movements normally in actual use and improves the sensitivity of the smart toilet's movements.
[0124] In practical applications, 80% ≤ M ≤ 100%.
[0125] In one exemplary embodiment, such as Figure 3 As shown, the operation includes a click action; determining whether the user's limb operation on the control pattern is a valid action is done by using millimeter waves, including: determining that the user's limb lands on the control pattern and then leaves the projection area; obtaining the dwell time of the user's limb on the control pattern; and determining whether the user's limb operation on the control pattern is a valid click action based on the dwell time.
[0126] Users can control the icons by clicking, that is, by clicking the corresponding function icon with their feet.
[0127] When judging user click actions, a click action can be determined as valid if the condition of "dwell time" is met. Specifically, when a user puts their foot into the control pattern (within the valid operation area), stays there for a period of time, and then leaves the projection area, if the dwell time meets the preset value, the click action can be determined as valid.
[0128] That is, the user's limb action on the control pattern is determined as a valid click action based on the dwell time, including: if the dwell time of the user's limb on the control pattern is greater than or equal to t1 and less than or equal to t2, it is determined as a valid click action; if the dwell time of the user's limb on the control pattern is less than t1 or greater than t2, it is determined as an invalid click action.
[0129] In practical applications, 0.5s≤t1<t2≤5s.
[0130] In one exemplary embodiment, such as Figure 3 As shown, the operation includes a sliding motion; determining whether the user's limb's operation on the control pattern is a valid action using millimeter waves includes: determining that the user's limb lands on the control pattern and slides, and then leaves the projection area; obtaining the dwell time and sliding motion of the user's limb on the control pattern; and determining whether the user's operation is a valid sliding motion based on the dwell time and sliding motion.
[0131] In addition to the aforementioned "user's operation on the control icon can be clicking", the user's operation on the control icon can also be swiping, that is, the user's foot lands on the corresponding function icon and swipes.
[0132] When judging a user's swipe action, a swipe action can be determined as valid if both the "dwell time" and "swipe direction" conditions are met. Specifically, when a user places their foot on the control pattern (within the valid operation area), stays for a period of time, and then swipes in a set direction, if the "dwell time" and "swipe direction" meet preset values, the swipe action can be determined as valid.
[0133] That is, the system determines whether a user's operation is a valid sliding action based on the dwell time and the sliding motion, including: if the user's limb dwells on the control pattern for a set period of time and then slides in a set direction after the dwell time, it is determined to be a valid sliding action; if the user's limb dwells on the control pattern for a set period of time and then does not slide in a set direction after the dwell time, it is determined to be an invalid sliding action.
[0134] This application also provides a control device, such as... Figure 5 As shown, the control device includes a processor, a memory, and a computer program stored in the memory and executable on the processor. When the computer program is executed by the processor, it implements the steps of the aforementioned control method. Figure 5 The image shows, for example, a portion of a computer program stored in memory.
[0135] After the control pattern is projected onto the projection area by the laser projector 42, the millimeter-wave radar device 41 detects whether the user's foot clicks on the control pattern. After the millimeter-wave radar device 41 recognizes that the user has clicked on the corresponding control pattern, the control device controls the toilet body 1 to perform flushing, cleaning and other operations.
[0136] In specific applications, the millimeter-wave radar device 41 can detect and identify the user's foot-lifting and clicking action, determine whether the user has triggered the relevant control pattern (whether a valid operation has been performed), and then send the determination result information to the control device, which decides whether to issue a command to control the smart toilet to perform flushing, cleaning, and other operations; alternatively, the millimeter-wave radar device 41 can detect and identify the user's foot-lifting and clicking action, send the detection result information to the control device, which determines whether the user has triggered the relevant control pattern (whether a valid operation has been performed), and then decides whether to issue a command to control the smart toilet to perform flushing, cleaning, and other operations.
[0137] This application also provides a smart toilet, such as... Figure 4 As shown, the smart toilet includes a toilet body 1, a millimeter-wave radar device 41, and the aforementioned control device. The control device is connected to the millimeter-wave radar device 41. The millimeter-wave radar device 41 is installed inside the toilet body 1.
[0138] The millimeter-wave radar device 41 and the control device can both be installed inside the toilet body 1.
[0139] This application embodiment also provides a toilet control system, which includes the aforementioned smart toilet; the toilet control system further includes a projector, which is signal-connected to a control device, and is used to project control patterns in front of or to the side of the toilet body 1; or, the toilet control system further includes a marker disposed in front of or to the side of the toilet body 1, the marker displaying the control patterns. The projector may be a laser projector 42.
[0140] In practical applications, millimeter-wave radar devices can be part of a home control system. A control unit communicates with the millimeter-wave radar and, based on the signals received from the radar, controls the toilet and / or projector to perform corresponding actions. Similarly, a projector can also be part of a home control system, with a control unit communicating with it to control the projector to project control patterns.
[0141] A through hole can be made on the wall of the toilet body 1 to allow the light from the laser projector 42 to pass through, while millimeter waves can pass directly through the ceramic body without the need for additional openings. That is, in this embodiment of the application, this smart toilet using millimeter waves reduces the number of openings on the wall.
[0142] The pattern projected by the laser projector 42 passes through the toilet body 1 and forms a control pattern 52 in front of or to the side of the toilet body 1. That is, the projection area 51 can be located on the ground or wall in front of the toilet body 1, or on the wall or ground to the side of the toilet body 1.
[0143] The laser projector 42 can be set to multiple groups to project different control patterns 52.
[0144] Furthermore, by displaying the control pattern to the user in advance by pasting stickers with the control pattern on the ground, it is possible to achieve the effect of not needing to drill holes in the toilet body 1, which greatly improves the integrity of the toilet body 1 and reduces the manufacturing cost of the smart toilet.
[0145] The smart toilet provided in this application embodiment can simultaneously detect the user's foot lifting operation, identify the specific position of the user's foot, and detect whether the user is close to the toilet through the millimeter-wave radar device 41. The millimeter-wave radar device 41 replaces the existing "infrared sensor + image recognition camera", which simplifies the structure of the smart toilet and protects the user's privacy.
[0146] In one exemplary embodiment, the millimeter-wave radar device 41 is located below the laser projector 42 in the height direction of the toilet body 1.
[0147] The millimeter-wave radar device 41 is located at a low position to facilitate the identification of the user's exact foot position.
[0148] In one exemplary embodiment, the smart toilet also includes a seat ring 3 rotatably connected to the toilet body 1 and a pressure sensor mounted on the seat ring 3, the pressure sensor being configured to detect whether the user is sitting down.
[0149] The pressure sensor can identify whether the user is sitting on the smart toilet, so as to provide a basis for the laser projector 42 to project the first type of control pattern 52 or the second type of control pattern 52.
[0150] Of course, in practical applications, other components can also be used to detect whether a user is sitting down, such as using an infrared sensor to detect whether a user is sitting on a smart toilet.
[0151] This application also provides a control method for an electronic device, which includes: projecting a control pattern onto a projection area; determining whether a user has performed a valid operation on the control pattern using millimeter waves; and controlling the electronic device to perform a corresponding action based on the user's valid operation on the control pattern.
[0152] The control method provided in this application can be used not only on smart toilets, but also on other electronic devices that can interact with users. This application does not limit this application.
