[0022] Current smart toilets require all heating elements to be activated to heat the entire seat when the heating function is turned on, ensuring the user doesn't feel uncomfortable due to a cold seat. While this control method ensures a good user experience, the heating elements in the non-contact areas of the seat operate in the same way as those in the contact areas, leading to some resource waste and higher power consumption.

[0023] To address the aforementioned shortcomings, this disclosure proposes a method for heating a toilet, such as... Figure 1 As shown, the method includes the following steps.

[0024] Step 110: Detect the contact area between the user and the seat ring.

[0025] In this embodiment, the seat of the smart toilet is pre-divided into multiple heating zones, and each heating zone is equipped with a heating device for heating that zone.

[0026] The following is combined Figure 2 Provide an example, such as Figure 2 As shown, the seat ring 200 is pre-divided into 9 heating zones, namely heating zones 1 to 9. Each heating zone is equipped with a heating element 210, which can heat the heating zone it belongs to. It should be noted that the position of the heating element 210 here is only an example and does not represent the actual installation position.

[0027] In this embodiment, the contact area refers to the area where the toilet seat contacts the user's body when the user sits on it. In a specific example, sensors, such as capacitive sensing electrodes or pressure sensors, can be placed at multiple locations on the toilet seat (e.g., within the cavity formed by the upper and lower covers of the seat). When the user sits on the seat, the sensor signal in the area in contact with the user will change, thus allowing the contact area between the user and the seat to be determined based on the sensor signal.

[0028] Step 120: Identify the target heating area that intersects with the contact area from multiple heating areas.

[0029] Further integration Figure 2 For example, when a user sits on a seat with a 200mm ring, the seating area is as follows: Figure 2 As shown, the area where the sitting area overlaps with the seat ring 200 is the contact area, and the heating areas that intersect with the contact area are heating areas 2, 3, 4, 6, 7 and 8. Therefore, the target heating areas are heating areas 2, 3, 4, 6, 7 and 8.

[0030] Step 130: Adjust the heating power of the heating device in the target heating area so that the temperature of the target heating area reaches the first preset temperature.

[0031] After the user sits on the seat, the heat dissipation of the contact area is low and the heat is not easily lost. At this time, the heating power of the heating device in the target heating area can be appropriately reduced, which can maintain the temperature of the contact area and reduce power consumption.

[0032] Combination Figure 2 For example, the power of the heating device 210 in heating zones 2, 3, 4, 6, 7 and 8 can be adjusted to about 50% of the rated power, and the first preset temperature can be close to the human body temperature, for example, 33 to 37°C.

[0033] In some optional embodiments of this example, the heating power of the heating devices in the heating areas adjacent to the target heating area can also be adjusted so that the temperature in that heating area reaches a first preset temperature. In this way, when the user moves slightly during use, they will not experience discomfort due to the lower temperature of the adjacent area.

[0034] like Figure 2 As shown, when adjusting the power of the heating device 210 in heating zones 2, 3, 4, 6, 7 and 8, the heating device 210 in heating zones 1 and 9 can also be adjusted.

[0035] Understandably, when the user finishes using the toilet, such as when the user gets up, flushes, or closes the toilet lid, the heating can be stopped, that is, all heating devices can be turned off, in order to avoid wasting resources.

[0036] The toilet heating method in this embodiment can determine the corresponding target heating area based on the contact area between the user and the seat ring, and then control the temperature of the target heating area and the heating power of the heating device. This achieves differentiated control of the seat ring temperature and the heating device power by area, ensuring user experience while being more energy-efficient and environmentally friendly.

[0037] Next, refer to Figure 3 , Figure 3 A schematic flowchart of yet another embodiment of the toilet heating method of this disclosure is shown, as follows: Figure 3 As shown, the process includes the following steps.

[0038] Step 310: In response to the triggering of the preset condition, control all heating devices to heat at the first preset power so that the temperature of multiple heating areas reaches the second preset temperature.

[0039] Among them, the preset conditions represent the user's expectation of using a smart toilet.

[0040] As an example, preset conditions could be detecting actions such as a user approaching the smart toilet, opening the toilet lid, or lowering the seat, which can be achieved by setting corresponding sensors on the smart toilet or seat.

[0041] A higher first preset power means a shorter heating time, resulting in a better user experience. Therefore, the first preset power can be a relatively high value, such as the rated power of the heating element or close to its rated power. The second preset temperature can be, for example, between 33 and 37°C.

[0042] Step 320: Detect the contact area between the user and the seat ring.

[0043] Step 330: Identify the target heating area that intersects with the contact area from multiple heating areas.

[0044] Step 340: After a preset time, adjust the heating power of the heating device in the target heating area to the third preset power.

[0045] The third preset power is less than the first preset power.

[0046] Since the temperature in the contact area is not easily lost and the heat dissipation rate is slow, the energy consumption required to maintain the temperature of this area is also low. By appropriately reducing the heating power of the heating device in the target heating area, the temperature of the contact area can be maintained and the energy consumption can be reduced.

[0047] The preset duration can be set based on experience, or it can be determined based on the time required for the user to sit down and the heating time required to reach the second preset temperature in step 310. The larger of the two values ​​is usually not less than the preset duration to avoid affecting the user experience. As an example, if the heating time required to reach the second preset temperature is 10 seconds, and the time required for the user to move from approaching the smart toilet to sitting down is 20 seconds, then the preset duration can be 25 seconds; if the time required to reach the second preset temperature is 50 seconds, and the time required from detecting the user's approach to the smart toilet to sitting down is 20 seconds, then the preset duration can be 1 minute.

[0048] Step 350: Adjust the power of the heating device in the non-target heating area to the second preset power, so that the temperature of the non-target heating area reaches the third preset temperature.

[0049] The second preset power is less than the first preset power.

[0050] Since the non-target heating area does not come into contact with the user, the heating time requirement is lower. Therefore, the second preset power can be less than the first preset power. For example, the second preset power can be 60 to 80% of the rated power.

[0051] In this embodiment, the non-target heating area refers to the area that the user has not touched. Heating the temperature of the non-target heating area to the third preset temperature can, on the one hand, prevent the user from feeling uncomfortable when moving to a new area due to the lower temperature of the new area; on the other hand, since the third preset power is less than the first preset power, energy consumption can be further reduced compared to heating the entire seat area.

[0052] In a specific example, a smart toilet can be equipped with a human body sensor. When the sensor detects a user approaching the toilet (i.e., a preset condition is triggered), it can control all heating elements to operate at their rated power (i.e., the first preset power), raising the temperature of all heated areas to 35°C (i.e., the second preset temperature). Once the user sits down, sensors on the seat can detect the contact area between the user and the seat and determine the target heating area (e.g., ...). Figure 2 Heating areas 2, 3, 4, 6, 7, and 8) and non-target heating areas (e.g.) Figure 2 The system operates in heating zones 1, 5, and 9. The heating elements in the non-target heating zones are then controlled to heat at 70% of their rated power (the second preset power) to raise the temperature of these zones to 34°C (the third preset temperature). After one minute (the preset duration), the heating elements in the target heating zone are adjusted to 50% of their rated power (the third preset power) to raise the temperature of these zones to 33°C (the first preset temperature). When the human body sensor detects that the user has moved away from the smart toilet, all heating elements are turned off, stopping the heating process.

[0053] In this embodiment, when it is predicted that the user expects to use the toilet, all heating devices are controlled to heat the entire area of ​​the seat ring at high power. This can prevent the user from feeling uncomfortable due to the low temperature of the seat ring when sitting for the first time. Then, according to the contact area between the user and the seat ring, the heating power of the heating devices in the target heating area is adjusted accordingly to reduce energy consumption. This can balance user experience and energy saving.

[0054] The following is for reference. Figure 4 , Figure 4 A schematic flowchart of yet another embodiment of the toilet heating method of this disclosure is shown, as follows: Figure 4 As shown, the process includes the following steps.

[0055] Step 410: In response to the triggering of the preset condition, control all heating devices to heat at the first preset power so that the temperature of multiple heating areas reaches the second preset temperature.

[0056] Step 420: Detect the contact area between the user and the seat ring.

[0057] Step 430: Identify the target heating area that intersects with the contact area from multiple heating areas.

[0058] Step 440: Determine the overlapping area between the contact area and each target heating area.

[0059] In this embodiment, the overlapping area represents the intersection of the contact area and the target heating area, which can reflect the degree to which the target heating area is covered by the user's body part. The overlapping area between the target heating area and the contact area may also be different at different locations.

[0060] Step 450: Based on the overlapping area corresponding to each target heating area, determine the third preset power corresponding to each target heating area.

[0061] Among them, the third preset power is negatively correlated with the size of the overlapping region.

[0062] A larger overlapping area indicates a higher degree of coverage of the target heating area, resulting in slower heat loss and lower heat requirements for temperature control. Therefore, a relatively low power can be used as the third preset power. Furthermore, a relatively low temperature can be used as the first preset temperature, meaning the first preset temperature is negatively correlated with the size of the overlapping area corresponding to the target heating area.

[0063] As an example, the third preset power can be determined based on the area of ​​the overlapping region (which can be the surface area or the projected area in the horizontal plane). When the area of ​​the overlapping region is equal to the area of ​​the target heating region or the area of ​​the overlapping region is greater than the area threshold, it means that the target heating region is completely covered. In this case, the third preset power can be set to 25-50% of the rated power, and the first preset temperature corresponding to the heating region can be set to 32-36℃. When the area of ​​the overlapping region is less than the area threshold, it means that the target heating region is partially covered. In this case, the third preset power can be set to 50-75% of the rated power, and the first preset temperature corresponding to the heating region can be set to 30-35℃.

[0064] In another example, the third preset power can also be determined by the following steps: determining the ratio of the area of ​​the overlapping area corresponding to each target heating area to the area of ​​the target heating area; if the ratio is greater than a preset threshold, the product of the predetermined first proportional coefficient and the rated power of the heating device is determined as the third preset power; if the ratio is not greater than the preset threshold, the product of the predetermined second proportional coefficient and the rated power is determined as the third preset power.

[0065] Among them, the maximum value of the range of the first proportional coefficient is not greater than the maximum value of the range of the second proportional coefficient.

[0066] As an example, the preset threshold can be 0.5, the first proportional coefficient can be in the range of [0.25, 0.5], and the second proportional coefficient can be in the range of [0.5, 0.75]. Combined with... Figure 2For example: If the ratio of the area of ​​the overlapping area corresponding to heating region 2 to the area of ​​heating region 2 is less than 0.5, then the second proportionality coefficient corresponding to heating region 2 can be taken as 0.6, and the third preset power of heating device 210 in heating region 2 is 60% of the rated power. If heating region 3 is completely covered by the contact area, then the first proportionality coefficient corresponding to heating region 3 can be taken as 0.25, and the third preset power of heating device 210 in heating region 3 is 25% of the rated power.

[0067] In this example, the ratio of the area of ​​the overlapping region to the area of ​​the target heating region can characterize the degree of coverage of the target heating region. This determines the proportional coefficient and then the third preset power corresponding to the target heating region. This can link the heat dissipation of the target heating region with the heating power of the heating device, which helps to improve the accuracy of temperature control and power control.

[0068] Step 460: After a preset time, adjust the heating power of the heating device in the target heating area to the third preset power.

[0069] Step 470: Adjust the power of the heating device in the non-target heating area to the second preset power, so that the temperature of the non-target heating area reaches the third preset temperature.

[0070] exist Figure 4 In the illustrated embodiment, the third preset power of each target heating area is determined based on the overlapping area between the contact area and each target heating area. This allows for more refined control of the temperature and power of each target heating area, which helps to improve the accuracy of temperature and power control and thus further reduce energy consumption.

[0071] Next, refer to Figure 5 , Figure 5 A schematic flowchart of an embodiment of the method for controlling temperature according to this disclosure is shown, such as... Figure 5 As shown, the process includes the following steps.

[0072] Step 510: In response to the triggering of the preset condition, control all heating devices to heat at the first preset power so that the temperature of multiple heating areas reaches the second preset temperature.

[0073] Step 520: Detect the contact area between the user and the seat ring.

[0074] Step 530: Identify the target heating area that intersects with the contact area from multiple heating areas.

[0075] Step 540: Adjust the heating power of the heating device in the target heating area so that the temperature of the target heating area reaches the first preset temperature.

[0076] Step 550: Adjust the power of the heating device in the non-target heating area to the second preset power, so that the temperature of the non-target heating area reaches the third preset temperature.

[0077] Step 560: When user movement is detected, update the contact area according to the user's new position.

[0078] In practice, users may move their bodies after sitting on the seat, causing changes in the contact area. In this case, the user's position after movement can be re-detected, and the contact area updated accordingly. The target heating area is then updated based on the updated contact area. Finally, steps 540 and 550 described above are used to complete temperature control of the entire seat area and power control of the heating devices.

[0079] It should be noted that, due to the uncertainty of the user's movement behavior after sitting down, the triggering time of step 560 may be at any time between step 520 and step 550. Therefore, this embodiment does not limit the execution order of step 560.

[0080] Figure 5 In the embodiment shown, when user movement is detected, the contact area and target heating area can be updated according to the user's new position, and the corresponding heating device can be adjusted, which helps to further improve the accuracy of the control of toilet temperature and heating power.

[0081] This disclosure also provides a toilet seat, such as... Figure 6 As shown, the toilet seat includes a seat body 610 and a control circuit (not shown in the figure). The seat body includes a mounting part 611, an upper cover 612 that contacts the user, and a lower cover 613 that contacts the toilet. The mounting part 611 is used to rotatably fix the seat body 610 to the toilet. The upper cover 612 and the lower cover 613 are fastened together to form an annular receiving cavity. A plurality of heating devices 620 are distributed in an annular manner in the receiving cavity. Each heating device 620 is used to heat a preset area to form a plurality of annularly distributed heating areas in the receiving cavity. Each heating area is provided with a temperature sensor (not shown in the figure) and an inductive sensor (not shown in the figure). The temperature sensor is used to detect the temperature of the upper cover in the heating area, and the inductive sensor is used to detect the contact area between the user and the upper cover 612. The control board is electrically connected to the heating devices 620, the temperature sensor, and the inductive sensor, and controls the temperature of the upper cover 612 by the toilet heating method in any of the aforementioned embodiments.

[0082] In this embodiment, the preset areas can be uniformly distributed or determined based on the usage of the toilet seat. For example, the contact probability between each area of ​​the toilet seat and the user can be statistically determined. Areas with a high contact probability can be divided into multiple smaller preset areas with decreasing intervals, while areas with a low contact probability can be divided into several larger preset areas with varying intervals. Each preset area can be equipped with one or more heating devices to heat the area, thus forming a heated area. Each preset area can be equipped with a temperature sensor to detect the temperature within that area. Additionally, each preset area can also be equipped with multiple inductive sensors, distributed at various locations within the preset area, to detect the contact status between the preset area and the user.

[0083] The toilet seat ring provided in this embodiment can use an inductive sensor to detect the contact area between the user and the toilet seat ring, and control the power of each heating device according to the contact area, thereby achieving temperature control of the toilet seat ring. This allows for more accurate temperature control of the toilet seat ring and is more energy-efficient and environmentally friendly.

[0084] In some optional embodiments of this example, the control motherboard is provided with a thyristor electrically connected to the heating device 620, and is configured to send a PWM signal to the thyristor to control the heating power of the heating device 620.

[0085] As an example, the heating element 620 can be an aluminum foil heater, and the control board can send a PWM signal to the silicon controlled rectifier (SCR) to control the heating power of the aluminum foil. This helps improve the control accuracy of the heating element's power.

[0086] In some optional embodiments of this example, the toilet seat also includes a human body sensor electrically connected to a control board, which is further configured to determine whether a user is approaching or moving away from the toilet seat based on the signal from the human body sensor.

[0087] In this embodiment, by sensing user movements through a human body sensor, the user's intentions can be predicted, so that the toilet seat can be controlled accordingly based on the user's intentions. For example, the heating function can be turned on in advance, which helps to further improve the intelligence of the toilet seat and the user experience.
