[0031] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0032] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0033] In one embodiment, Figure 1 This is a flow chart of a water outlet control method based on a smart toilet provided by an embodiment of the present invention. This embodiment is applicable to the case of dynamically adjusting the spray pressure of a smart toilet. The method can be executed by a water outlet control device based on a smart toilet. The water outlet control device based on a smart toilet can be implemented in the form of hardware and / or software. The water outlet control device based on a smart toilet can be configured in a smart toilet. Figure 1 As shown, the method includes:

[0034] S110 : In response to receiving a cleaning start instruction, determining a target hot water outlet temperature and a target cold water outlet temperature according to the cleaning start instruction.

[0035] In one example, a cleaning start instruction refers to an instruction or signal used to trigger a smart toilet to perform a specific cleaning function. In actual operation, a cleaning start instruction can be issued to a smart toilet by physical button operation, sensor operation, or APP control. In one example, when a physical button operation is used to issue a cleaning start instruction, various function buttons can be configured on the operation panel of the smart toilet, and when a button related to a cleaning function triggered by the user is received, a cleaning start instruction can be automatically issued; when a sensor operation is used to issue a cleaning start instruction, a sensor function can be configured in the smart toilet, and the cleaning start instruction can be automatically triggered in the case of human proximity sensing or gesture sensing; when an APP control method is used to issue a cleaning start instruction to a smart toilet, the user can click the corresponding cleaning function option on the APP interface to enable the APP to automatically issue a cleaning start instruction to the smart toilet.

[0036] In one example, the cleaning start instruction includes different cleaning modes. For example, the cleaning modes may include, but are not limited to, at least one of the following: buttocks wash mode, feminine wash mode, child wash mode, and massage wash mode. In another example, the cleaning start instruction also includes a target hot water outlet temperature and a target cold water outlet temperature. The target hot water outlet temperature refers to the temperature of the hot water outlet from the spray rod of the smart toilet, for example, the target hot water outlet temperature can be 40°C; the target cold water outlet temperature refers to the temperature of the cold water outlet from the spray rod of the smart toilet, for example, the target cold water outlet temperature can be 23°C.

[0037] In actual operation, a mapping relationship can be established between the cleaning mode and the target hot water outlet temperature and the target cold water outlet temperature, and the mapping relationship can be stored in the memory of the smart toilet. The cleaning mode can be included in the cleaning start instruction, and the corresponding target hot water outlet temperature and target cold water outlet temperature can be determined based on the carried cleaning mode and the mapping relationship. In one example, the target hot water outlet temperature and target cold water outlet temperature can be directly included in the cleaning start instruction. After the smart toilet receives the cleaning start instruction, the cleaning start instruction can be parsed by the processor in the smart toilet to obtain the corresponding target hot water outlet temperature and target cold water outlet temperature.

[0038] S120: adjusting the actual jet pressure of the smart toilet according to the temperature changes between the target hot water outlet temperature and the target cold water outlet temperature and the actual water inlet temperature, so as to control the water flow of the smart toilet.

[0039] In one example, the actual jet pressure represents the pressure at which water is ejected from the jet outlet of a smart toilet during a flush operation; the outlet flow rate represents the volume and velocity of water flowing from the jet outlet during a flush operation. Generally speaking, the actual jet pressure of a smart toilet determines the impact force of the outlet flow, and the actual jet pressure is proportional to the impact force of the outlet flow: the greater the actual jet pressure, the greater the impact force of the outlet flow. Generally speaking, the actual jet pressure affects the velocity and flow rate of the outlet flow. Generally speaking, the actual jet pressure is proportional to the velocity of the outlet flow: the greater the actual jet pressure, the faster the velocity of the outlet flow. To a certain extent, the actual jet pressure also affects the flow rate of the outlet flow. Generally speaking, the greater the actual jet pressure, the greater the volume of water ejected per unit time.

[0040] In one example, the temperature change between the target hot water outlet temperature and the actual water inlet temperature is used to characterize the temperature difference between the target hot water outlet temperature and the actual water inlet temperature; the temperature change between the target cold water outlet temperature and the actual water inlet temperature is used to characterize the temperature difference between the target cold water outlet temperature and the actual water inlet temperature.

[0041] In actual operation, the water outlet process of the smart toilet can include at least four stages: a heating stage, a constant temperature stage based on target hot water outlet temperature control, a cooling stage, and a constant temperature stage based on cold water outlet temperature control.

[0042] In one example, during the heating stage, the actual spray pressure of the smart toilet can be reduced synchronously according to the temperature difference between the target hot water outlet temperature and the actual water inlet temperature, so as to control the water outlet flow of the smart toilet to be relatively reduced, and thus the heating process of the water flow can be completed as soon as possible, that is, the water outlet temperature can reach the target hot water outlet temperature as soon as possible.

[0043] In one example, in the constant temperature stage based on the target hot water outlet temperature control, the actual spray pressure of the smart toilet can be synchronously and alternately adjusted according to the temperature difference between the target hot water outlet temperature and the actual water inlet temperature, so as to alternately increase or decrease the water outlet flow of the smart toilet. In this way, the water outlet flow of the smart toilet can be kept at the target hot water outlet temperature while the actual spray pressure of the water outlet flow can be alternately adjusted, and the size of the water outlet flow of the smart toilet can be alternately increased or decreased, so that the user can have a flushing and massage function on the user's buttocks during the flushing process, thereby improving the user experience.

[0044] In one example, during the cooling stage, the actual spray pressure of the smart toilet can be increased synchronously according to the temperature difference between the target cold water outlet temperature and the actual water inlet temperature to control the relative increase of the water outlet flow of the smart toilet, thereby completing the cooling process of the water flow as soon as possible, that is, making the water outlet temperature reach the target cold water outlet temperature as soon as possible.

[0045] In one example, in the constant temperature stage based on the target cold water outlet temperature control, the actual spray pressure of the smart toilet can be synchronously and alternately adjusted according to the temperature difference between the target cold water outlet temperature and the actual water inlet temperature, so as to alternately increase or decrease the water outlet flow of the smart toilet. In this way, the water outlet flow of the smart toilet can be kept at the target cold water outlet temperature while the actual spray pressure of the water outlet flow can be alternately adjusted, and the size of the water outlet flow of the smart toilet can be alternately increased or decreased, so that the user can have a flushing and massage function on the user's buttocks during the flushing process, thereby improving the user experience.

[0046] The technical solution of the embodiment of the present invention determines the target hot water outlet temperature and the target cold water outlet temperature according to the cleaning start instruction when the smart toilet receives the cleaning start instruction. Without adding any additional cold water tank and hot water tank, that is, without adding any additional hardware and structural costs of the smart toilet, the function of alternating hot and cold water to clean the buttocks is effectively realized; and the actual spray pressure of the smart toilet is adjusted according to the temperature change between the target hot water outlet temperature and the actual water inlet temperature to control the water flow of the smart toilet, and the actual spray pressure of the smart toilet is adjusted according to the temperature change between the target cold water outlet temperature and the actual water inlet temperature to control the water flow of the smart toilet. This solves the technical problem in the prior art that the spray pressure of the smart toilet cannot be dynamically adjusted according to the water outlet temperature, resulting in a poor flushing experience for the user. It effectively realizes the dynamic adjustment of the spray pressure of the smart toilet based on the water outlet temperature, thereby meeting the flushing needs of different users, thereby effectively improving the user experience.

[0047] In one embodiment, Figure 2 This is a flow chart of another water outlet control method based on a smart toilet provided by an embodiment of the present invention. This embodiment further details the process of adjusting the actual injection pressure and determining the outlet water temperature based on the above embodiment. Figure 2 As shown, the method includes:

[0048] S210 : In response to receiving a cleaning start instruction, identifying and extracting a cleaning mode in the cleaning start instruction.

[0049] In one example, the cleaning mode refers to the different working modes set by the smart toilet to meet different user needs and cleaning scenarios by controlling the characteristics of the water flow and the nozzle movement.

[0050] Typically, the control panel or remote control of a smart toilet will display buttons or icons corresponding to different cleaning modes. For example, the "hip wash mode" may be an icon shaped like a buttock or a button labeled "hip wash" on the control panel; the "female wash mode" may be an icon shaped like a woman or a button labeled "female wash" on the control panel.

[0051] When the processor of the smart toilet receives the cleaning start instruction, it directly determines the cleaning mode in the cleaning start instruction based on the triggering operation of the corresponding button or icon.

[0052] S220: Determine a target hot water outlet temperature and a target cold water outlet temperature according to the cleaning mode.

[0053] In one example, a mapping relationship can be established between different cleaning modes and the target hot water outlet temperature and the target cold water outlet temperature respectively; after the cleaning mode is identified, the target hot water outlet temperature and the target cold water outlet temperature of the smart toilet are automatically determined based on the cleaning mode and the mapping relationship between the two.

[0054] S230. Synchronously adjust the duty cycle of the water inlet pump in the smart toilet according to the temperature changes between the target hot water outlet temperature and the target cold water outlet temperature and the actual water inlet temperature.

[0055] In one example, the duty cycle of a water inlet pump represents the ratio of the time the water inlet pump is powered on to the total cycle time within a pulse cycle. This means that the larger the duty cycle, the longer the water inlet pump is powered on per unit time, and the greater the water flow rate.

[0056] In one example, during the heating stage, the pump duty cycle of the water inlet pump in the smart toilet can be synchronously reduced according to the temperature difference between the target hot water outlet temperature and the actual water inlet temperature to reduce the actual injection pressure of the smart toilet.

[0057] In one example, in the constant temperature stage based on the target hot water outlet temperature control, the pump duty cycle of the water inlet pump in the smart toilet can be synchronously and alternately adjusted according to the temperature difference between the target hot water outlet temperature and the actual water inlet temperature, so as to alternately increase or decrease the actual injection pressure of the smart toilet, that is, alternately increase or decrease the outlet water flow of the smart toilet, so that the outlet water flow of the smart toilet can be alternately adjusted while maintaining the target hot water outlet temperature, and then the size of the outlet water flow of the smart toilet can be alternately increased or decreased.

[0058] In one example, during the cooling stage, the pump duty cycle of the water inlet pump in the smart toilet can be increased synchronously according to the temperature difference between the target cold water outlet temperature and the actual water inlet temperature to increase the actual injection pressure of the smart toilet.

[0059] In one example, in the constant temperature stage based on the target cold outlet water temperature control, the pump duty cycle of the water inlet pump in the smart toilet can be synchronously and alternately adjusted according to the temperature difference between the target cold outlet water temperature and the actual inlet water temperature, so as to alternately increase or decrease the actual spray pressure of the smart toilet, that is, to alternately increase or decrease the outlet water flow of the smart toilet, so that the outlet water flow of the smart toilet can be maintained at the target cold outlet water temperature while the actual spray pressure of the outlet water flow can be alternately adjusted, and then the size of the outlet water flow of the smart toilet can be alternately increased or decreased.

[0060] S240. Synchronously adjust the valve opening of the water inlet valve in the smart toilet according to the temperature changes between the target hot water outlet temperature and the target cold water outlet temperature and the actual water inlet temperature.

[0061] In one example, the valve opening of the water inlet valve refers to the degree to which the valve is opened. It can be understood that the larger the valve opening, the greater the water flow of the water inlet pump per unit time.

[0062] In one example, during the temperature rise phase, the valve opening of the water inlet valve in the smart toilet can be synchronously reduced according to the temperature difference between the target hot water outlet temperature and the actual water inlet temperature to reduce the actual injection pressure of the smart toilet.

[0063] In one example, in the constant temperature stage based on the target hot water outlet temperature control, the valve opening of the water inlet valve in the smart toilet can be synchronously and alternately adjusted according to the temperature difference between the target hot water outlet temperature and the actual water inlet temperature to alternately increase or decrease the actual spray pressure of the smart toilet, that is, alternately increase or decrease the water outlet flow of the smart toilet, so that the water outlet flow of the smart toilet can be maintained at the target hot water outlet temperature while the actual spray pressure of the water outlet flow can be alternately adjusted, and then the size of the water outlet flow of the smart toilet can be alternately increased or decreased.

[0064] In one example, during the cooling stage, the valve opening of the water inlet valve in the smart toilet can be synchronously increased according to the temperature difference between the target cold water outlet temperature and the actual water inlet temperature to increase the actual injection pressure of the smart toilet.

[0065] In one example, in the constant temperature stage based on the target cold outlet water temperature control, the valve opening of the water inlet valve in the smart toilet can be synchronously and alternately adjusted according to the temperature difference between the target cold outlet water temperature and the actual inlet water temperature to alternately increase or decrease the actual spray pressure of the smart toilet, that is, to alternately increase or decrease the outlet water flow of the smart toilet, so that the outlet water flow of the smart toilet can be maintained at the target cold outlet water temperature while the actual spray pressure of the outlet water flow can be alternately adjusted, and then the size of the outlet water flow of the smart toilet can be alternately increased or decreased.

[0066] The technical solution of this embodiment, based on the above-mentioned embodiment, automatically identifies and extracts the cleaning mode from the cleaning start instruction when receiving the cleaning start instruction, and determines the target hot water outlet temperature and the target cold water outlet temperature according to the cleaning mode, effectively ensuring the accuracy of determining the target hot water outlet temperature and the target cold water outlet temperature; and, based on the temperature changes between the target hot water outlet temperature and the target cold water outlet temperature and the actual water inlet temperature, synchronously adjusts the pump duty cycle of the water inlet pump in the smart toilet, or synchronously adjusts the valve opening of the water inlet valve in the smart toilet according to the temperature changes between the target hot water outlet temperature and the target cold water outlet temperature and the actual water inlet temperature, controls the actual spray pressure of the smart toilet from different angles, and then controls the water outlet flow of the smart toilet. On the basis of effectively realizing the dynamic adjustment of the spray pressure of the smart toilet based on the outlet water temperature to meet the flushing needs of different users, it also realizes water supply on demand, avoids water resource waste, and extends the service life of the equipment.

[0067] In one embodiment, the actual spray pressure of the smart toilet is adjusted synchronously according to the temperature changes between the target hot water outlet temperature and the target cold water outlet temperature and the actual water inlet temperature, including at least one of the following:

[0068] When the water flow is heated according to the target hot water outlet temperature and the actual water inlet temperature, the actual jet pressure of the smart toilet is synchronously reduced according to the temperature change between the target hot water outlet temperature and the actual water inlet temperature;

[0069] Under the condition that the water flow is thermostatically controlled according to the target hot water outlet temperature and the actual water inlet temperature, the actual jet pressure of the smart toilet is synchronously and alternately adjusted according to the temperature change between the target hot water outlet temperature and the actual water inlet temperature;

[0070] Under the condition that the water flow is cooled and controlled according to the target cold water outlet temperature and the actual water inlet temperature, the actual spray pressure of the smart toilet is increased synchronously according to the temperature change between the target cold water outlet temperature and the actual water inlet temperature;

[0071] While the water flow is thermostatically controlled according to the target cold water outlet temperature and the actual water inlet temperature, the actual jet pressure of the smart toilet is synchronously and alternately adjusted according to the temperature change between the target cold water outlet temperature and the actual water inlet temperature.

[0072] In one example, a hot and cold water alternating cycle may include a temperature rising stage, a constant temperature stage controlled based on a target hot water outlet temperature, a temperature falling stage, and a constant temperature stage controlled based on a target cold water outlet temperature.

[0073] In one example, when controlling the water flow temperature based on the target hot water outlet temperature and the actual inlet water temperature, the actual spray pressure of the smart toilet is synchronously reduced based on the temperature difference between the target hot water outlet temperature and the actual inlet water temperature to control the water flow of the smart toilet. For example, the duty cycle of the water inlet pump in the smart toilet can be adjusted to 46%. In one example, the process of controlling the water flow temperature based on the target hot water outlet temperature and the actual inlet water temperature is described as follows:

[0074] In one example, the hot and cold water alternation cycle refers to the time interval and regularity of the cold and hot water cycle switching when the smart toilet performs the hot and cold water alternation cleaning function. The hot and cold water alternation cycle can be characterized by different time units, such as minutes (min), seconds (s), and milliseconds (ms). For example, a hot and cold water alternation cycle can be 10s. In one example, a hot and cold water alternation cycle includes at least: the duration of hot water and the duration of cold water; wherein the duration of hot water may include: the heating duration and the constant temperature duration; the duration of cold water may include: the cooling duration and the constant temperature duration.

[0075] In one example, the actual inlet water temperature refers to the real-time temperature of the water flowing into the smart toilet as it enters the water inlet valve. During actual operation, the water inlet valve is connected to the water inlet pump, which is connected to the water inlet temperature sensor. The real-time temperature of the water entering the water inlet valve can be monitored in real time by the water inlet temperature sensor and used as the actual inlet water temperature.

[0076] It should be noted that since the internal water channel of the smart toilet is of a certain length, when the actual water inlet temperature is initially collected, the water inlet temperature sensor will be affected by the temperature of the residual water, resulting in the collected water inlet temperature being higher than the actual water inlet temperature. At this time, in order to ensure the accuracy of the actual water inlet temperature, the residual water in the smart toilet can be discharged first. For example, after the smart toilet receives the cleaning start command, the smart toilet can be controlled to discharge water for a period of time to ensure that the collected water inlet temperature is the actual water inlet temperature.

[0077] In this embodiment, after receiving a flush start command, the smart toilet can activate the instant heating module during the first hot and cold water alternation cycle based on the temperature difference between the target hot water outlet temperature and the actual water inlet temperature to heat the water flow and achieve the target hot water outlet temperature as much as possible, thereby achieving the water temperature increase control process. It should be noted that during the water temperature increase control process, in order to ensure the water temperature increases faster, the instant heating module can be activated at full power to significantly reduce the time required for water heating.

[0078] In one example, when the water flow is thermostatically controlled according to the target hot water outlet temperature and the actual water inlet temperature, the actual jet pressure of the smart toilet is synchronously increased or decreased according to the temperature difference between the target hot water outlet temperature and the actual water inlet temperature, so as to synchronously increase or decrease the water flow of the smart toilet. It can be understood that when the water flow is thermostatically controlled according to the target hot water outlet temperature and the actual water inlet temperature, the actual jet pressure of the smart toilet is synchronously adjusted by pulsating water pressure. For example, the duty cycle of the water inlet pump in the smart toilet can be adjusted between 46% and 100%. In one example, the process of thermostatically controlling the water flow according to the target hot water outlet temperature and the actual water outlet temperature is explained:

[0079] In one example, the water flow is thermostatically controlled according to the target hot water outlet temperature and the actual water outlet temperature. This can be understood as thermostatically controlling the hot water area of ​​the smart toilet, i.e. maintaining the water outlet temperature as stable as possible at the target hot water outlet temperature.

[0080] In an embodiment, an incremental PID algorithm can be used to control the water flow to maintain at the target hot water outlet temperature, and the actual water outlet temperature is read every once in a while, and based on the actual water outlet temperature and the target hot water outlet temperature, the incremental PID algorithm is called to adjust the water flow temperature so that the water outlet temperature of the water flow is maintained at the target hot water outlet temperature.

[0081] In one example, when cooling water flow based on a target cold water outlet temperature and the actual inlet water temperature, the actual spray pressure of the smart toilet is increased synchronously based on the temperature difference between the target cold water outlet temperature and the actual inlet water temperature. For example, the duty cycle of the water inlet pump in the smart toilet can be adjusted to 100%. In one example, the process of cooling water flow based on the target cold water outlet temperature and the actual inlet water temperature is described as follows:

[0082] In one example, after completing the constant temperature control process for the hot water zone, the instant heating module can be controlled to shut down, stopping the water heating process. In actual operation, to accelerate the cooling process, the water inlet pump duty cycle can be adjusted to the maximum value to maximize the inlet water flow. This achieves rapid cooling of the water flow without increasing the hardware and structural costs of the smart toilet.

[0083] In one example, when the water flow is thermostatically controlled according to the target cold outlet water temperature and the actual inlet water temperature, the actual jet pressure of the smart toilet is alternately increased or decreased synchronously according to the temperature difference between the target cold outlet water temperature and the actual inlet water temperature. It can be understood that when the water flow is thermostatically controlled according to the target cold outlet water temperature and the actual inlet water temperature, the actual jet pressure of the smart toilet is synchronously adjusted using pulsating water pressure. For example, the duty cycle of the water inlet pump in the smart toilet can be adjusted between 46% and 100%. In one example, the process of thermostatically controlling the water flow according to the target cold outlet water temperature and the actual outlet water temperature is explained:

[0084] In one example, the water flow is thermostatically controlled according to the target cold water outlet temperature and the actual water outlet temperature. This can be understood as thermostatically controlling the cold water area of ​​the smart toilet, i.e. maintaining the water outlet temperature as stable as possible at the target cold water outlet temperature.

[0085] In an embodiment, when the target cold outlet water temperature is greater than the actual outlet water temperature, an incremental PID algorithm can be used to heat the water flow, and after the heating is completed, an incremental PID algorithm can be used to control the water flow to maintain at the target cold outlet water temperature, and the actual outlet water temperature is read once every period of time, and based on the actual outlet water temperature and the target cold outlet water temperature, the incremental PID algorithm is called to adjust the temperature of the water flow so that the outlet water temperature of the water flow is maintained at the target cold outlet water temperature; when the target cold outlet water temperature is lower than the actual outlet water temperature, the actual outlet water temperature can be directly used to perform constant temperature control on the water flow, that is, the temperature of the water flow is controlled to maintain at the actual outlet water temperature.

[0086] The technical solution of this embodiment is to determine the target hot water outlet temperature and the target cold water outlet temperature according to the cleaning start instruction when the smart toilet receives the cleaning start instruction, and within a hot and cold water alternation cycle, the water flow can be controlled to increase in temperature according to the target hot water outlet temperature and the actual water inlet temperature; the water flow can be controlled to be at a constant temperature according to the target hot water outlet temperature and the actual water outlet temperature; the water flow can be controlled to decrease in temperature according to the target cold water outlet temperature and the actual water inlet temperature; and the water flow can be controlled to be at a constant temperature according to the target cold water outlet temperature and the actual water outlet temperature. Without the need to add additional cold water tanks and hot water tanks, the function of washing the buttocks with alternating hot and cold water is effectively realized, thereby greatly reducing the hardware and structural costs of the smart toilet.

[0087] In one embodiment, the water outlet control method based on the smart toilet further includes: determining a desired spray pressure and a spray pressure adjustment method according to a cleaning mode;

[0088] The actual jet pressure adjustment process of the smart toilet includes one of the following:

[0089] When the spray pressure adjustment mode is a step-by-step adjustment mode, the actual spray pressure of the smart toilet is synchronously reduced to the desired spray pressure according to the temperature change between the target hot water outlet temperature and the actual water inlet temperature;

[0090] When the jet pressure adjustment mode is a sudden adjustment mode, the actual jet pressure of the smart toilet is suddenly reduced to the desired jet pressure according to the temperature change between the target hot water outlet temperature and the actual water inlet temperature;

[0091] When the spray pressure adjustment mode is a step-by-step adjustment mode, the actual spray pressure of the smart toilet is synchronously and alternately adjusted to the desired spray pressure according to the temperature change between the target hot water outlet temperature and the actual water inlet temperature;

[0092] When the jet pressure adjustment mode is a sudden adjustment mode, the actual jet pressure of the smart toilet is suddenly adjusted to the desired jet pressure according to the temperature change between the target hot water outlet temperature and the actual water inlet temperature;

[0093] When the spray pressure adjustment mode is a step-by-step adjustment mode, the actual spray pressure of the smart toilet is synchronously increased to the desired spray pressure according to the temperature change between the target cold water outlet temperature and the actual water inlet temperature;

[0094] When the jet pressure adjustment mode is a sudden adjustment mode, the actual jet pressure of the smart toilet is suddenly increased to the desired jet pressure according to the temperature change between the target cold water outlet temperature and the actual water inlet temperature;

[0095] When the spray pressure adjustment mode is a step-by-step adjustment mode, the actual spray pressure of the smart toilet is synchronously and alternately adjusted to the desired spray pressure according to the temperature change between the target cold water outlet temperature and the actual water inlet temperature;

[0096] When the injection pressure adjustment mode is a sudden adjustment mode, the actual injection pressure of the smart toilet is adjusted alternately and suddenly to the desired injection pressure according to the temperature change between the target cold water outlet temperature and the actual water inlet temperature.

[0097] In one example, the desired spray pressure refers to the spray pressure that matches the cleaning mode, and can also be understood as the spray pressure that fully matches the user's cleaning needs. The desired spray pressure can also be referred to as the ideal spray pressure. The spray pressure adjustment method refers to the method of adjusting the current spray pressure of the smart toilet to the desired spray pressure. The spray pressure adjustment method may include, but is not limited to, at least one of the following: a step-by-step adjustment method and a sudden adjustment method. The step-by-step adjustment method refers to a method of slowly adjusting the current spray pressure of the smart toilet to the desired spray pressure. For example, if the current spray pressure is 20 kPa (kilopascals) and the desired spray pressure is 30 kPa, the current spray pressure of the smart toilet can be directly adjusted from 20 kPa to 22 kPa, then to 24 kPa, and finally gradually adjusted to 30 kPa. The sudden adjustment method refers to a method of suddenly adjusting the current spray pressure of the smart toilet to the desired spray pressure. For example, if the current spray pressure is 20 kPa (kilopascals) and the desired spray pressure is 30 kPa, the current spray pressure of the smart toilet can be directly adjusted from 20 kPa to 30 kPa.

[0098] In one example, during the heating stage, and when the spray pressure adjustment method is a step-by-step adjustment method, the actual spray pressure of the smart toilet is synchronously and gradually reduced to the desired spray pressure according to the temperature change between the target hot water outlet temperature and the actual water inlet temperature.

[0099] In one example, during the temperature rise phase, when the spray pressure adjustment mode is a sudden change adjustment mode, the actual spray pressure of the smart toilet is directly and suddenly reduced to the desired spray pressure according to the temperature change between the target hot water outlet temperature and the actual water inlet temperature;

[0100] During the constant temperature phase controlled by the target hot water outlet temperature, and using a step-by-step pressure adjustment method, the smart toilet's actual pressure is synchronously and alternately adjusted to the desired pressure based on the temperature variation between the target hot water outlet temperature and the actual water inlet temperature. For example, if user 1 prefers gentle pressure control and avoids sudden pressure changes, or suffers from hemorrhoids, they can use a sudden pressure adjustment method to adjust the pressure. If the current pressure is 20 kPa (kilopascals) and the desired pressures are 30 kPa and 10 kPa, the smart toilet's pressure can be adjusted directly from 20 kPa to 22 kPa, then to 24 kPa, and then gradually to 30 kPa. Then, from 30 kPa, it can be reduced to 28, 26, 24, ... 18, 16, 14, and 12 kPa.

[0101] During the constant temperature stage controlled by the target hot water outlet temperature, and when the jet pressure adjustment method is a sudden adjustment method, the actual jet pressure of the smart toilet is adjusted alternately and suddenly to the desired jet pressure according to the temperature change between the target hot water outlet temperature and the actual water inlet temperature. For example, if user 1 desires stimulation, has an itchy buttocks, or eats spicy food, the jet pressure can be adjusted using a sudden adjustment method. Assuming the current jet pressure is 20kPa (kilopascals), and the desired jet pressures are 30kPa and 10kPa, the current jet pressure of the smart toilet can be adjusted directly from 20kPa to 30kPa; and then directly reduced from 30kPa to 12kPa.

[0102] In the cooling stage, when the spray pressure adjustment method is a step-by-step adjustment method, the actual spray pressure of the smart toilet is synchronously increased to the desired spray pressure according to the temperature change between the target cold water outlet temperature and the actual water inlet temperature;

[0103] In the cooling stage, if the jet pressure adjustment mode is a sudden adjustment mode, the actual jet pressure of the smart toilet is suddenly increased to the desired jet pressure according to the temperature change between the target cold water outlet temperature and the actual water inlet temperature;

[0104] In the constant temperature stage based on the target cold water outlet temperature control, and when the spray pressure adjustment method is a step-by-step adjustment method, the actual spray pressure of the smart toilet is synchronously and alternately adjusted to the desired spray pressure according to the temperature change between the target cold water outlet temperature and the actual water inlet temperature;

[0105] In the constant temperature stage based on the target cold water outlet temperature control, and when the injection pressure adjustment method is a sudden adjustment method, the actual injection pressure of the smart toilet is suddenly adjusted alternately to the desired injection pressure according to the temperature change between the target cold water outlet temperature and the actual water inlet temperature.

[0106] The technical solution of this embodiment determines the target hot water outlet temperature and the target cold water outlet temperature, as well as the expected spray pressure and the spray pressure adjustment method based on the cleaning mode, and uses different spray pressure adjustment methods to adjust the actual spray pressure of the smart toilet to the expected spray pressure at different stages, thereby meeting the cleaning needs of different users and improving the user experience.

[0107] In one embodiment, Figure 3This is a flow chart of a water temperature control method based on a smart toilet provided by an embodiment of the present invention. This embodiment further details the temperature control process based on the above embodiment. In the embodiment, the time required for the water flow to heat up to the target hot water outlet temperature is recorded as the first actual heating time, the heating power required for the water flow to heat up to the target hot water outlet temperature is recorded as the first initial heating power, and the number of heating half waves is recorded as the first actual heating half wave number. Figure 3 As shown, the method includes:

[0108] S310 : In response to receiving a cleaning start instruction, determining a target hot water outlet temperature and a target cold water outlet temperature according to the cleaning start instruction.

[0109] S320: In a hot and cold water alternation cycle, determine a first actual temperature rise time according to the target hot water outlet temperature, the actual water inlet temperature, and a predetermined unit temperature rise value and unit time.

[0110] In one example, a unit duration refers to a preconfigured, fixed time period used to measure time. For example, the unit duration can be a full-power heating cycle or a cycle in which the duty cycle of a water pump varies. The unit duration can be expressed in different time units, such as milliseconds (ms) or microseconds (μs). For example, the unit duration can be 200 ms.

[0111] In one example, the unit temperature rise value refers to the temperature value that the water flow can rise in a unit time. For example, when the unit time is 200 ms, the unit temperature rise value refers to the temperature value that the water flow can rise in every 200 ms.

[0112] In one example, the first actual heating time refers to the time required to heat the water flow from the actual inlet water temperature to the target hot outlet water temperature. In one example, the temperature difference between the target hot outlet water temperature and the actual inlet water temperature can be determined, and then the temperature difference can be ratioed by the unit temperature rise value. The ratio between the two can then be multiplied by the unit time to obtain the first actual heating time. For example, the first actual heating time is denoted as tr1, where tr1 = (Ts_H - Ti) / 1.24 * 0.2; where Ts_H represents the target hot outlet water temperature, Ti represents the actual inlet water temperature, 1.24°C represents the unit temperature rise value, and 0.2s represents the unit time.

[0113] Exemplarily, tr1 = Q / P = (C*m*ΔT) / (P*ηth);

[0114] Where tr1 is the heating time (seconds); Q is the required heat (joules, J); P is the heating power (watts, W); c is the specific heat capacity of water; m is the mass of water (kg, which can be converted from the water flow rate Vs); ΔT is the temperature difference (target temperature Ts_h - initial temperature Ti, °C); ηth is the thermal efficiency, for example, 0.95

[0115] Example: Assume the heating power P is 1000W, the water flow rate Vs is 0.3293L / min (needs to be converted to kg / s, 1L water ≈ 1kg); the water pump duty cycle is 46%, and the flow rate at the water pump duty cycle of 46% is: vs = 0.3293 / 60

[0116] =0.005488kg / s; target hot water outlet temperature is 40℃, actual water inlet temperature is 20℃; temperature difference ΔT: =40℃-20℃=20℃;

[0117] Then, calculate the heating capacity per unit time, the energy required to heat the water per second:

[0118] Q=c*m*ΔT=cVs*t*ΔT=P*ηth*t; therefore, cVsΔT=P.

[0119] The water flow rate Vs is 0.3293 L / min (needs to be converted to kg / s, 1 L of water ≈ 1 kg). The flow rate at a duty cycle of 46% is: vs = 0.3293 / 60 = 0.005488 kg / s;

[0120] Assuming that the full power is 200W, the unit temperature rise per 200ms is ΔT1 = (K*P*ηth) / (c*Vs) = K1*0.95 / (4180*0.005488) = 1.24°C. K1 is an empirical coefficient, for example, 0.75 can be used.

[0121] S330: When the current duration is within the first actual heating duration and the current duration has not reached the first hot and cold water alternation cycle, determine the first initial heating power according to the target hot water outlet temperature, the actual water inlet temperature and the actual water flow rate.

[0122] In one example, the first initial heating power refers to the heating power required to increase the temperature of the water flow to the target hot water outlet temperature in the first hot and cold alternating cycle.

[0123] In one example, the first initial heating power Wh1 = [Vs*ΔT*C]* / (60s*ηth);

[0124] Where C is the specific heat capacity of water; ΔT is the temperature difference (target hot water outlet temperature Ts_h – actual water inlet temperature Ti, in °C); ηth is the thermal efficiency; and Vs is the actual flow rate of the water.

[0125] S340: Determine the first actual number of heating half-waves according to the first initial heating power, the maximum power of the heating plate, and the total number of half-waves contained in a unit time.

[0126] In one example, the number of the first actual heating half-waves refers to the number of levels required for heating, which can also be understood as the number of high levels in a heating cycle.

[0127] In an embodiment, the product of the ratio of the first initial heating power to the maximum power of the heating plate and the total number of half-waves contained in the unit time is taken as the first actual number of heating half-waves.

[0128] For example, the maximum power of the heating plate is 1000; the total number of half-waves contained in one unit time / heating cycle is 20, and the number of the first actual heating half-waves = Wh / 1000*20.

[0129] Among them, the heating cycle is 200ms, and one heating cycle has 20 half waves. Since the heating power is about 1000W, one heating cycle is 200W, and the number of heatings is: (first initial heating power Wh / total power of the heating plate)*20.

[0130] S350: Use the first actual heating half-wave number to control the temperature of the water flow.

[0131] In an embodiment, the heating process of the water flow is controlled based on the first actual heating half-wave number to achieve temperature rise control of the water flow and control the temperature of the water flow to reach the target hot water outlet temperature.

[0132] S360: Perform constant temperature control on the water flow according to the target hot water outlet temperature and the actual hot water outlet temperature.

[0133] S370: Control the water flow to cool down according to the target cold water outlet temperature and the actual water inlet temperature.

[0134] S380: Perform constant temperature control on the water flow according to the target cold water outlet temperature and the actual cold water outlet temperature.

[0135] In one embodiment, when the current duration is within the actual heating duration, the water temperature control method based on the smart toilet also includes: sending a flow rate control instruction carrying the first water pump duty cycle to the associated water inlet pump, so that the water inlet pump dynamically adjusts the water flow rate according to the first water pump duty cycle.

[0136] In one example, the first water pump duty cycle refers to the water pump duty cycle used by the water inlet pump during the heating phase. It should be noted that during the heating phase, to accelerate the heating of the water flow, that is, to shorten the time required for the water flow to heat from the actual outlet water temperature to the target hot outlet water temperature (i.e., the first actual heating time), the water inlet pump's water pump duty cycle can be adjusted to a minimum value. For example, if the minimum water inlet pump duty cycle is 46%, the first water pump duty cycle can be set to 46%.

[0137] In one embodiment, Figure 4 This is a flow chart of another water temperature control method based on a smart toilet provided by an embodiment of the present invention. This embodiment further details the constant temperature control process of the hot water area based on the above embodiment. Figure 4 As shown, the method includes:

[0138] S410 : In response to receiving a cleaning start instruction, determining a target hot water outlet temperature and a target cold water outlet temperature according to the cleaning start instruction.

[0139] S420: In a hot and cold water alternation cycle, the water flow is controlled to increase in temperature according to the target hot water outlet temperature and the actual water inlet temperature.

[0140] S430: When the current duration is within the first preset constant temperature duration, determine the actual temperature difference value according to the target hot water outlet temperature and the actual hot water outlet temperature.

[0141] In one example, the first preset constant temperature duration refers to the duration required to maintain the water temperature at the target hot water outlet temperature. For example, the first preset constant temperature duration may be 4 seconds. In another example, the current duration refers to the timer that is started upon entering the heating phase, and the duration of the timer is recorded as the current duration.

[0142] In an embodiment, when the current duration reaches the first actual heating duration, the constant temperature stage of the hot water zone is entered, and the timer is started again, and the difference between the target hot water outlet temperature and the actual water outlet temperature is used as the actual temperature difference.

[0143] S440: Using the actual temperature difference value, and calling the incremental PID formula to control the water flow constant temperature at the target hot water outlet temperature.

[0144] In an embodiment, an incremental PID formula is called to control the water flow to maintain at a target hot water outlet temperature, and the actual water outlet temperature is read every period of time, and based on the actual water outlet temperature and the target hot water outlet temperature, the incremental PID algorithm is called to adjust the temperature of the water flow so that the water outlet temperature of the water flow is maintained at the target hot water outlet temperature.

[0145] S450: Control the water flow to cool down according to the target cold water outlet temperature and the actual water inlet temperature.

[0146] S460: Perform constant temperature control on the water flow according to the target cold water outlet temperature and the actual cold water outlet temperature.

[0147] In one embodiment, Figure 5 This is a flow chart of another water temperature control method based on a smart toilet provided by an embodiment of the present invention. This embodiment further details the cooling control process based on the above embodiment. In the embodiment, the time required for the water flow to cool to the target cold outlet water temperature is recorded as the actual cooling time, the heating power for the water flow to cool to the target cold outlet water temperature is recorded as the second initial heating power, and the number of heating half waves is recorded as the second actual number of heating half waves. Figure 5 As shown, the method includes:

[0148] S510 : In response to receiving a cleaning start instruction, determining a target hot water outlet temperature and a target cold water outlet temperature according to the cleaning start instruction.

[0149] S520: In a hot and cold water alternation cycle, the water flow is controlled to increase in temperature according to the target hot water outlet temperature and the actual water inlet temperature.

[0150] S530: Perform constant temperature control on the water flow according to the target hot water outlet temperature and the actual hot water outlet temperature.

[0151] S540: When the target cold water outlet temperature is lower than the actual water inlet temperature, the actual water inlet temperature is used to control the water flow temperature.

[0152] During actual operation, when the target cold water outlet temperature is lower than the actual water inlet temperature, the actual water inlet temperature is used to control the water flow temperature, thereby achieving rapid cooling of the water flow without increasing the hardware and structural costs of the smart toilet.

[0153] S550: When the target cold water outlet temperature is greater than the actual water inlet temperature, determine the actual cooling time according to the target hot water outlet temperature, the actual water inlet temperature, and the target cold water outlet temperature.

[0154] Wherein, t=-[(mc / Rtotal]*ln[(Ts_c-Ti)) / (Ts_h-Ti)];

[0155] Ti represents the actual water inlet temperature; Ts_h represents the target hot water outlet temperature; Ts_c represents the target cold water outlet temperature; m is the mass of water (kg, which can be converted by the water flow rate Vs); Rtotal is the total thermal resistance.

[0156] For example, we can take K2 = [(mc / Rtotal];

[0157] t=-K2*ln[(Ttarget-Tambient)) / (Tinitial-Tambient)]==-K2*ln[(|Ttarget-Tin|) / (Tinitial-Tin)];

[0158] K2≈1.3619, an empirical value derived from measured data.

[0159] S560: When the current duration is within the actual cooling duration, determine the second initial heating power according to the target cold water outlet temperature, the actual water inlet temperature, and the actual flow rate of the water flow.

[0160] In one example, the second initial heating power refers to the heating power required to increase the temperature of the water flow to the target cold water outlet temperature in the first hot and cold alternating cycle.

[0161] In one example, the second initial heating power Wh2 = [Vs*ΔT*C]* / (60s*ηth);

[0162] Where C is the specific heat capacity of water; ΔT is the temperature difference (target cold water outlet temperature Ts_c – actual water inlet temperature Ti, in °C); ηth is the thermal efficiency; and Vs is the actual flow rate of the water.

[0163] S570: Determine the second actual number of heating half-waves according to the second initial heating power, the maximum power of the heating plate, and the total number of half-waves contained in the unit time.

[0164] In one example, the second actual heating half-wave number refers to the number of levels required for heating, which can also be understood as the number of high levels in a heating cycle.

[0165] In an embodiment, the product of the ratio of the second initial heating power to the maximum power of the heating plate and the total number of half-waves contained in the unit time is taken as the second actual number of heating half-waves.

[0166] For example, the maximum power of the heating plate is 1000; the total number of half-waves contained in one unit time / heating cycle is 20, and the number of the second actual heating half-waves = Wh / 1000*20.

[0167] Among them, the heating cycle is 200ms, and one heating cycle has 20 half waves. Since the heating power is about 1000W, one heating cycle is 200W, and the number of heatings is: (the second initial heating power Wh2 / total power of the heating plate)*20.

[0168] S580: Use the second actual heating half-wave number to control the temperature of the water flow so that the temperature of the water flow reaches the target cold water outlet temperature.

[0169] In an embodiment, the heating process of the water flow is controlled based on the first actual heating half-wave number to achieve temperature rise control of the water flow and control the temperature of the water flow to reach the target cold water outlet temperature.

[0170] S590: Perform constant temperature control on the water flow according to the target cold water outlet temperature and the actual cold water outlet temperature.

[0171] In one embodiment, Figure 6 This is a flow chart of another water temperature control method based on an intelligent toilet provided by an embodiment of the present invention. This embodiment further details the constant temperature control process of the cold water zone based on the above embodiment. Figure 6 As shown, the method includes:

[0172] S610 : In response to receiving a cleaning start instruction, determining a target hot water outlet temperature and a target cold water outlet temperature according to the cleaning start instruction.

[0173] S620: In a hot and cold water alternation cycle, the water flow is controlled to increase in temperature according to the target hot water outlet temperature and the actual water inlet temperature.

[0174] S630: Perform constant temperature control on the water flow according to the target hot water outlet temperature and the actual hot water outlet temperature.

[0175] S640: Control the water flow to cool down according to the target cold water outlet temperature and the actual water inlet temperature.

[0176] S650: When the target cold water outlet temperature is lower than the actual water inlet temperature, the actual water inlet temperature is used to perform constant temperature control on the water flow.

[0177] S660: When the target cold water outlet temperature is greater than the actual water inlet temperature and the current duration does not reach one hot and cold water alternation cycle, determine the actual temperature difference value according to the target cold water outlet temperature and the actual water outlet temperature.

[0178] In an embodiment, when the target cold water outlet temperature is greater than the actual water inlet temperature and the current duration does not reach a hot and cold water alternation cycle, the constant temperature stage of the cold water zone is entered, and the timer is started again, and the difference between the target cold water outlet temperature and the actual water outlet temperature is used as the actual temperature difference.

[0179] S670: Using the actual temperature difference, and calling the incremental PID formula to control the water flow constant temperature at the target cold water outlet temperature.

[0180] In an embodiment, an incremental PID formula is called to control the water flow to maintain at a target cold outlet water temperature, and the actual outlet water temperature is read every period of time, and based on the actual outlet water temperature and the target cold outlet water temperature, the incremental PID algorithm is called to adjust the temperature of the water flow so that the outlet water temperature of the water flow is maintained at the target cold outlet water temperature.

[0181] In one embodiment, during the constant temperature control process, the water temperature control method based on the smart toilet also includes: sending a flow rate control instruction carrying the first water pump duty cycle and the second water pump duty cycle to the associated water inlet pump, so that the water inlet pump alternately adjusts the water flow rate according to the first water pump duty cycle and the second water pump duty cycle.

[0182] In one example, the first water pump duty cycle and the second water pump duty cycle refer to the duty cycles used by the water inlet pump during the constant temperature phase. It should be noted that during the constant temperature phase, to ensure that different water flow rates achieve a cleansing and massage effect, for example, the first water pump duty cycle can be set to 46% and the second water pump duty cycle to 63%, with the water flow rate adjusted alternately between 46% and 63%.

[0183] In one embodiment, the water temperature control method based on the smart toilet further includes:

[0184] When the current duration reaches the first hot and cold water alternation cycle, the current duration is reset to zero;

[0185] Determining a second actual heating time according to the target hot water outlet temperature, the actual water outlet temperature, and a predetermined unit temperature rise value and unit time;

[0186] When the current duration after clearing reaches the second actual heating duration and the current duration is not in the first hot and cold water alternation cycle, return to the step of determining the first initial heating power based on the target hot water outlet temperature, the actual water inlet temperature and the actual flow rate of the water flow.

[0187] In one embodiment, Figure 7 This is a flow chart of another water temperature control method based on a smart toilet provided by an embodiment of the present invention. Based on the above embodiment, this embodiment, as a preferred embodiment, describes the water temperature control process of a smart toilet.

Figure 8 As shown, a hot and cold water alternation cycle includes a temperature rising zone, a hot water zone, a temperature falling zone and a cold water zone, which respectively correspond to the above-mentioned temperature rising stage, the constant temperature stage based on the target hot water outlet temperature control, the temperature falling stage and the constant temperature stage based on the cold water outlet temperature control.

[0214] In one embodiment, Figure 9 This is a schematic diagram of the structure of a water outlet control device based on a smart toilet provided by an embodiment of the present invention. Figure 9 As shown, the device includes: a first determining module 910 and a control module 920.

[0215] A first determining module 910 is configured to, in response to receiving a cleaning start instruction, determine a target hot water outlet temperature and a target cold water outlet temperature according to the cleaning start instruction;

[0216] The control module 920 is used to adjust the actual spray pressure of the smart toilet according to the temperature changes between the target hot water outlet temperature and the target cold water outlet temperature and the actual water inlet temperature, so as to control the water outlet flow of the smart toilet.
