Description

Technical Field

[0001] This invention relates to sanitary appliances, and in particular to a method for controlling the drying of a toilet and a toilet. Background Technology

[0002] Existing technology CN113686140A discloses a rapid drying device with a surge air outlet control method, including a fan, an air duct, and a controller. A temperature control device is installed within the air duct. The controller controls the fan speed and the operation of the temperature control device. The fan speed changes in a pulse mode. Within a period T, during time interval t1, the controller controls the fan speed to be A, and during time interval t2, the controller controls the fan speed to be B, where A and B are not equal. In the drying device of this invention, under certain conditions of outlet temperature or fan speed, the fan speed alternates between fast and slow, or the outlet temperature alternates between high and low, thereby achieving alternating fast and slow or high and low temperature airflow from the drying device. This creates a feeling of natural wind blowing, achieving rapid drying while preventing localized burning sensations on the skin, thus improving user comfort.

[0003] However, the existing technology does not take into account the actual humidity of the user's body surface. It simply controls the air speed and temperature in a pulse-like manner. The control method is relatively mechanical. In actual use, users may experience a situation where they are exposed to a cold and strong wind when their body surface is wet, resulting in a feeling of being too cold. Alternatively, they may experience a situation where they are exposed to a hot wind when their body surface is dry, resulting in a feeling of being too hot. Summary of the Invention

[0004] The purpose of this invention is to provide a method for controlling the drying of a toilet, which solves the problem of excessively cold or hot temperatures during the drying process and improves user comfort.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a toilet drying control method, comprising the following contents:

[0006] S1. After the user finishes using the washing device, obtain the user's current body surface humidity, compare the user's current body surface humidity with the set humidity threshold Δt, and determine the outlet air temperature, speed and duration of the drying device.

[0007] S2. After the drying device has been operating for a predetermined time, the user's current body surface humidity is obtained again, and the user's current body surface humidity is compared with the set humidity threshold Δt again, so as to determine the outlet air temperature, speed and operating duration of the drying device again. This process is repeated until the user's current body surface humidity is compared with the set humidity threshold Δt and it is determined that warm air drying is no longer needed.

[0008] After adopting the above technical solution, the present invention has the following advantages: the air outlet temperature, speed and duration of the drying device are determined according to the user's current body surface humidity. At the same time, it is divided into multiple time periods, and the air outlet temperature, speed and duration of the drying device can be different in each time period. Thus, the drying work can be carried out in a targeted manner according to the user's current body surface humidity, ensuring that the drying work carried out in the current time period can adapt to the user's current body surface temperature. This avoids the situation where the user feels too cold due to low temperature and strong wind when there is a lot of water on their body surface, or the situation where the user feels too hot due to high temperature and hot wind when there is little water on their body surface, thereby improving the user's comfort.

[0009] Furthermore, the user's current body surface humidity status in S1 is the humidity data obtained through direct detection. 实 , through th 实 The outlet air temperature, velocity, and duration of operation of the drying device are determined by comparing with Δt.

[0010] Furthermore, it also includes the following:

[0011] S0. Detect the user's skin surface moisture level before using the washing device. 初 and store the th 初 ;

[0012] The user's current body surface humidity level in S1 is humidity data obtained through direct detection. 实 Compared with the user's body surface moisture level before using the washing device. 初 The comparison value Δth is used to determine the outlet air temperature, speed, and duration of operation of the drying device by comparing Δth with Δt.

[0013] Furthermore, the set humidity threshold Δt is set to three, corresponding to humidity conditions from high to low as Δt1, Δt2 and Δt3 respectively;

[0014] If the user's current body surface humidity is ≥Δt1, the drying device will start working with an outlet air temperature K1 and an outlet air speed Y1, and the duration of the drying device's operation will be T1.

[0015] If Δt1 > the user's current body surface humidity ≥ Δt2, the drying device is determined to start working with an outlet air temperature K2 and an outlet air speed Y2, and the duration of the drying device's operation is T2.

[0016] If Δt2 > the user's current body surface humidity ≥ Δt3, the drying device is determined to start working with an outlet air temperature K3 and an outlet air speed Y3, and the duration of the drying device's operation is T3.

[0017] If the user's current body surface humidity is ≤Δt3, then it is determined that warm air drying is no longer needed;

[0018] Where K1>K2≥K3, Y1<Y2, Y3<Y2, T1≥T2≥T3.

[0019] Furthermore, if the user's current body surface humidity is ≥Δt1, after the drying device starts working, the outlet air temperature gradually decreases from K1 to K2, and the outlet air speed gradually increases from Y1 to Y2.

[0020] Furthermore, if Δt1 > the user's current body surface humidity ≥ Δt2, after the drying device starts working, the outlet air temperature remains unchanged at K2, and the outlet air speed remains unchanged at Y2.

[0021] Furthermore, if Δt2 > the user's current body surface humidity ≥ Δt3, after the drying device starts working, the outlet air temperature gradually decreases from K3 to K4, the outlet air speed gradually decreases from Y2 to Y3, and K4 < K3.

[0022] Furthermore, K3 = K2; and / or, Y3 = Y1.

[0023] The present invention also provides a toilet, including a controller and a drying device. The drying device includes a fan and a heater electrically connected to the controller. The toilet is equipped with a photoelectric humidity sensor for detecting the humidity of the user's body surface. The controller controls the operation of the drying device according to the toilet drying control method described in any of the above technical solutions.

[0024] Furthermore, the toilet is also equipped with a second humidity sensor for detecting the humidity of the air outlet of the drying device. The humidity of the user's body surface is determined by comparing the signal value detected by the photoelectric humidity sensor with the signal value detected by the second humidity sensor.

[0037] The technical solution of the present invention will be described in detail below with reference to specific embodiments. The following specific embodiments may be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0038] This invention provides a method for controlling the drying of a toilet, comprising the following:

[0039] S1. After the user finishes using the washing device, obtain the user's current body surface humidity, compare the user's current body surface humidity with the set humidity threshold Δt, and determine the outlet air temperature, speed and duration of the drying device.

[0040] S2. After the drying device has been operating for a predetermined time, the user's current body surface humidity is obtained again, and the user's current body surface humidity is compared with the set humidity threshold Δt again, so as to determine the outlet air temperature, speed and operating duration of the drying device again. This process is repeated until the user's current body surface humidity is compared with the set humidity threshold Δt and it is determined that warm air drying is no longer needed.

[0041] This invention determines the air outlet temperature, speed, and duration of the drying device based on the user's current skin moisture level. It also divides the process into multiple time periods, each with different air outlet temperatures, speeds, and durations. This allows for targeted drying based on the user's skin moisture level, ensuring the drying process is adapted to the user's current skin temperature. This prevents situations where a user with excessive skin moisture experiences excessive cold from a cold, strong airflow, or a user with insufficient skin moisture experiences excessive heat from a hot, high-temperature airflow, thus improving user comfort.

[0042] To obtain the user's current body surface humidity, in one embodiment, the user's current body surface humidity in S1 is the humidity data obtained through direct detection. 实 , through th 实 The outlet air temperature, velocity, and duration of operation of the drying device are determined by comparing with Δt. For example, a photoelectric humidity sensor can be used to detect the user's skin humidity. Specifically, a photoelectric humidity sensor can be installed in the toilet to detect the user's skin humidity. The user's skin humidity is determined based on the signal value detected by the photoelectric humidity sensor. The th value is obtained through direct detection. 实The data acquisition is relatively direct and simple, reducing the calculation process and allowing the drying device to respond more quickly. The working principle of the photoelectric humidity sensor is relatively easy to understand. Because water molecules can absorb electromagnetic radiation of a certain range and discrete wavelengths, the attenuation of a certain segment of radiation absorbed by water vapor is measured along the path from the radiation source to the receiving device. The method for measuring the degree of radiation attenuation mainly involves emitting radiation of two wavelengths and recording the ratio of the emission intensity of these two wavelengths. One wavelength of radiation is strongly absorbed by water vapor, while the other wavelength is not absorbed or is barely absorbed. By comparing the ratio of the received intensity of the two wavelengths of radiation measured at the receiver with the recorded ratio of the emission intensity, the radiation attenuation of the absorbed wavelength can be measured, thereby determining the humidity of the surface of the object being detected.

[0043] Understandably, besides the humidity data obtained through direct detection... 实 In another embodiment, the toilet drying control method further includes the following:

[0044] S0. Detect the user's skin surface moisture level before using the washing device. 初 and store the th 初 ;

[0045] The user's current body surface humidity level in S1 is humidity data obtained through direct detection. 实 Compared with the user's body surface moisture level before using the washing device. 初 The comparison value Δth is used to determine the outlet air temperature, speed, and duration of the drying device by comparing Δth with Δt. In this embodiment, the user's current skin surface humidity is determined by comparison. Since it can be assumed that the user's skin surface humidity is dry before using the washing device, using the humidity change as a reference allows for a more accurate restoration of the user's current skin surface humidity to the state before using the washing device, resulting in a more accurate result.

[0046] In addition, a second humidity sensor can be installed in the toilet to detect the humidity at the dryer's air outlet. The user's skin humidity is determined by comparing the signal value detected by the photoelectric humidity sensor with that detected by the second humidity sensor. Since the humidity at the dryer's air outlet is relatively stable, it can serve as a reference point, making the determination of the user's skin humidity more accurate. Furthermore, the... 初 By comparing the relative humidity of the user's skin with that of the air outlet of the drying device, and using this as a reference, the accuracy of the test results can be ensured.

[0047] In a practical application, three humidity thresholds Δt can be set, corresponding to humidity conditions from high to low as Δt1, Δt2 and Δt3 respectively.

[0048] If the user's current body surface humidity is ≥Δt1, the drying device will start working with an outlet air temperature K1 and an outlet air speed Y1, and the duration of the drying device's operation will be T1.

[0049] If Δt1 > the user's current body surface humidity ≥ Δt2, the drying device is determined to start working with an outlet air temperature K2 and an outlet air speed Y2, and the duration of the drying device's operation is T2.

[0050] If Δt2 > the user's current body surface humidity ≥ Δt3, the drying device is determined to start working with an outlet air temperature K3 and an outlet air speed Y3, and the duration of the drying device's operation is T3.

[0051] If the user's current body surface humidity is ≤Δt3, then it is determined that warm air drying is no longer needed;

[0052] Where K1>K2≥K3, Y1<Y2, Y3<Y2, T1≥T2≥T3.

[0053] By designing a high-temperature, low-speed airflow pattern to address situations where the user's skin humidity is high (≥Δt1), the device allows water to evaporate quickly without causing the user to feel hot. As the user's skin humidity gradually decreases, satisfying Δt1 > ≥ Δt2, the drying device uses a slightly higher temperature and higher speed airflow. The increased airflow speed after the warm air temperature drops prevents the user from feeling hot. While drying the water on the skin, the airflow also blows the water away, improving drying efficiency. When the user's skin humidity continues to decrease, satisfying Δt2 > ≥ Δt3, the drying device uses a low-temperature, low-speed airflow pattern to prevent burns as the skin humidity decreases. This design not only provides a comfortable user experience but also ensures user safety.

[0054] Combination Figures 1 to 3See, to enhance user comfort when using the drying device, the following settings can be selected: If the user's current skin humidity is ≥Δt1, the outlet air temperature gradually decreases from K1 to K2, while the outlet air speed gradually increases from Y1 to Y2, using a gradual, stepless temperature and speed adjustment. This smooth change in warm air temperature and speed provides a more comfortable experience. During the drying process, if Δt1 > the user's current skin humidity is ≥Δt2, the outlet air temperature remains constant at K2, and the outlet air speed remains constant at Y2, achieving stable drying efficiency and shortening drying time. If Δt2 > the user's current skin humidity is ≥Δt3, the outlet air temperature gradually decreases from K3 to K4, and the outlet air speed gradually decreases from Y2 to Y3, where K4 < K3. The air outlet temperature and speed gradually decrease, which is also stepless temperature and speed regulation. This not only makes users feel more comfortable, but also gradually approaches the normal temperature of the user's body surface, reducing the user's discomfort after the drying process and improving comfort.

[0055] In addition to selecting and setting three humidity thresholds Δt, the number can be increased or decreased according to actual needs. The humidity of the user's skin is generally detected through pulse signals. Therefore, within time periods such as T1, T2, and T3, the user's current skin humidity can still be detected multiple times to obtain real-time changes in the user's skin humidity. If any abnormalities occur, the air outlet temperature, speed, and duration of the drying device can be adjusted promptly to prevent the user from being scalded.

[0056] In one embodiment, K3 can be set to K2 for smoother temperature control and greater user comfort. Alternatively, K3 < K2 or K3 > K2 can be selected based on actual needs.

[0057] In one embodiment, Y3 can be selected as Y1, so that the air outlet speed responds to the start and end of the drying process, providing a better user experience. Of course, Y3 < Y1 or Y3 > Y1 can also be selected according to actual needs.

[0058] like Figures 4 to 6 As shown, the present invention also provides a toilet, including a controller 100 and a drying device 200. The drying device 200 includes a fan 201 and a heater 202 electrically connected to the controller 100. The toilet is provided with a photoelectric humidity sensor 300 for detecting the humidity of the user's body surface. The controller 100 controls the drying device 200 to work according to the toilet drying control method in any of the above embodiments.

[0059] To improve the accuracy of humidity results, a second humidity sensor 301 can be installed in the toilet to detect the humidity at the air outlet of the drying device 200. The humidity of the user's body surface is determined by comparing the signal value detected by the photoelectric humidity sensor 300 with the signal value detected by the second humidity sensor 301. Specifically, the second humidity sensor 301 can be installed in the air outlet duct 204 or at the air outlet 203 of the drying device 200.

[0060] In addition to the preferred embodiments described above, the present invention has other embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection claimed by the present invention.
