Description

Technical Field

[0001] The invention relates to the field of sanitary ware, and in particular to a toilet deodorization control method and system. Background Art

[0002] The current mainstream deodorization systems generally rely on high-speed fans to drive the airflow, and improve the contact efficiency between odor molecules and catalytic media (such as activated carbon) through forced convection. However, the increase in fan power or speed directly leads to increased air turbulence, amplified mechanical vibrations, and high-frequency friction between the airflow and the wall of the air duct, which in turn causes significant noise pollution. This noise not only affects the user experience, but is also more likely to cause user resistance in scenarios such as home and medical settings that have strict requirements for silence, forming a technical contradiction between "efficient deodorization" and "comfortable experience."

[0003] Traditional noise reduction solutions mainly reduce noise by reducing fan speed or sacrificing air duct cross-sectional area, but such methods will directly weaken the efficiency of airflow exchange, resulting in prolonged odor retention time, insufficient catalyst reaction, and even secondary pollution risks. Some improved designs attempt to isolate noise by adding silencers, optimizing impeller shape, or adopting a split structure, but they face problems such as bloated size, rising costs, or increased maintenance complexity. Existing technologies have not yet achieved the coordinated optimization of "low wind speed-high purification efficiency-low cost", which restricts the scene adaptability of deodorization equipment. Summary of the invention

[0004] The main purpose of the present invention is to overcome the above-mentioned defects in the prior art and to propose a toilet deodorization control method and system, which adopts a staged control method to adjust the fan speed to match the deodorization requirements under different odor concentrations, effectively deodorizing while reducing the impact of noise on users, thereby creating a better experience.

[0005] The present invention adopts the following technical solution:

[0006] A toilet deodorization control method is used to control a deodorization component to deodorize the air in a toilet bowl. When the deodorization component starts the deodorization function, the deodorization work of the deodorization component is divided into a first deodorization stage, a second deodorization stage and a third deodorization stage.

[0007] In the first deodorization stage, the speed of the fan of the deodorization component is controlled to operate according to the first variation mode, so as to deodorize the gas in the toilet bowl with gradually increasing odor concentration;

[0008] In the second deodorization stage, the speed of the fan of the deodorization component is controlled to operate according to the set first speed, so as to deodorize the gas in the toilet bowl during the period of maximum odor concentration;

[0009] In the third deodorization stage, the speed of the fan of the deodorization component is controlled to operate according to the second variation mode, so as to deodorize the gas in the toilet bowl with gradually decreasing odor concentration.

[0010] The speed of the fan operates according to the first change mode, specifically: the fan is controlled to start at a speed corresponding to a first duty cycle, and the duty cycle is increased according to a set step size at set time intervals until the duty cycle reaches a set second duty cycle, and the first duty cycle is smaller than the second duty cycle.

[0011] The first duty cycle is less than or equal to 50%, the second duty cycle is greater than 50% and less than or equal to 100%, the time interval is 5S-10S, and the setting step is 10%.

[0012] The speed of the fan of the deodorizing component is controlled to operate at a set first speed, specifically, the fan is controlled to operate at a speed corresponding to a duty cycle of not less than 80%.

[0013] The speed of the fan operates according to the second change mode, specifically: controlling the fan to operate at a speed corresponding to the second duty cycle, and decreasing the duty cycle according to a set step size at set time intervals until the duty cycle reaches a set third duty cycle, and the third duty cycle is less than the second duty cycle.

[0014] The second duty cycle is greater than 50% and less than or equal to 80%, the third duty cycle is less than or equal to 40%, the time interval is 5S-10S, and the setting step is 10%.

[0015] The concentration of odor is determined by detecting the ammonia concentration or hydrogen sulfide concentration in the air in the toilet bowl. When the detected ammonia concentration or hydrogen sulfide concentration gradually increases, the deodorizing component is controlled to enter the first deodorizing stage; when the detected ammonia concentration or hydrogen sulfide concentration is within the set threshold range, the deodorizing component is controlled to enter the second deodorizing stage; when the detected ammonia concentration or hydrogen sulfide concentration gradually decreases, the deodorizing component is controlled to enter the third deodorizing stage.

[0016] It is configured that when a user sits down, the first deodorization stage, the second deodorization stage and the third deodorization stage are executed in chronological order, and the first deodorization stage lasts for a first time length, the second deodorization stage lasts for a second time length, and the third deodorization stage lasts for a third time length.

[0017] It is arranged that when the user sits down, the detection of the ammonia concentration or hydrogen sulfide concentration in the air in the toilet bowl is started to determine the concentration of the odor. When the detected ammonia concentration or hydrogen sulfide concentration gradually increases, the deodorizing component is controlled to enter the first deodorizing stage; when the detected ammonia concentration or hydrogen sulfide concentration is within the set threshold range, the deodorizing component is controlled to enter the second deodorizing stage; when the detected ammonia concentration or hydrogen sulfide concentration gradually decreases, the deodorizing component is controlled to enter the third deodorizing stage.

[0018] A toilet deodorization control system comprises a deodorization component and a control unit. The deodorization component is installed on the base of the toilet and is provided with an air inlet and an air outlet. The air inlet faces the toilet bowl, and the air outlet faces outside the toilet bowl. The control unit executes a toilet deodorization control method.

[0019] The deodorizing component comprises a shell, a fan and a deodorizing medium; the shell is provided with an air inlet duct and an air outlet duct, the air inlet duct is provided with an air inlet, the air outlet duct is provided with an air outlet, and the deodorizing medium is installed at the air outlet of the air outlet duct.

[0020] The size of the air inlet duct is set to gradually increase along the air inlet direction from the air inlet to the fan; the deodorizing medium adopts platinum catalyst or activated carbon.

[0021] It also includes an ammonia sensor or a hydrogen sulfide sensor, which is installed on the base to detect the ammonia concentration or hydrogen sulfide concentration in the air in the air inlet duct or the toilet bowl.

[0022] It can be seen from the above description of the present invention that, compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. In the present invention, the deodorization work of the deodorization component is divided into the first deodorization stage, the second deodorization stage and the third deodorization stage. By adjusting the fan speed in stages, the deodorization intensity is accurately matched with the rise and fall of the odor concentration in the toilet bowl. It can not only intervene in advance in the concentration climbing period to suppress the spread of odor, but also concentrate energy for efficient purification in the peak concentration period, realize the deodorization by gradually increasing the air volume in stages, and gradually reduce the air volume in the later stage of deodorization; and adopt progressive speed adjustment instead of constant high-speed operation to avoid energy waste caused by continuous high-power output. At the same time, the core purification efficiency is maintained by stabilizing the speed in the peak period, and a dynamic balance is established between noise reduction and deodorization efficiency.

[0024] 2. In the present invention, the speed of the fan works according to the first change mode, which is started at a speed corresponding to the first duty cycle, and the duty cycle is increased according to a set step size at each set time interval until the duty cycle reaches a set second duty cycle, which not only maintains the necessary airflow disturbance intensity, but also avoids the ineffective energy consumption of full-speed operation, and the speed can be increased to the target speed more quickly; the second change mode works by controlling the fan to work at a speed corresponding to the second duty cycle, and the duty cycle is decreased according to a set step size at each set time interval until the duty cycle reaches a set third duty cycle, thereby reducing the overall energy consumption and reducing the additional vibration noise caused by mechanical wear. It is particularly suitable for indoor scenes that are sensitive to noise.

[0025] 3. In the present invention, the concentration of ammonia or hydrogen sulfide in the air can be detected and compared with a plurality of preset thresholds to determine the change in odor concentration. Alternatively, the change trend of odor concentration can be indirectly inferred by combining the behavioral characteristics of the user using the toilet. The judgment can also be achieved by combining the two methods. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. DETAILED DESCRIPTION

[0037] The present invention is further described below through specific implementation modes.

[0038] See also Figure 1 The present invention provides a toilet deodorization control method, which is used to control the deodorization component to deodorize the air in the toilet bowl. The deodorization component mainly includes a fan and a deodorization medium. The fan serves as a power source to continuously drive the air flow to directionally pump the odor from the generating area to the deodorization medium. Through physical and chemical effects such as physical adsorption, chemical catalysis or biodegradation, ammonia or hydrogen sulfide and other substances are captured and decomposed and purified to achieve odor elimination.

[0039] In the method of the present invention, when the deodorizing component turns on the deodorizing function, the deodorizing work of the deodorizing component is divided into a first deodorizing stage, a second deodorizing stage, and a third deodorizing stage. In the first deodorizing stage, the speed of the fan of the deodorizing component is controlled to work according to the first variation mode, so as to deodorize the gas in the toilet bowl with gradually increasing odor concentration. In the second deodorizing stage, the speed of the fan of the deodorizing component is controlled to work according to the set first speed, so as to deodorize the gas in the toilet bowl with the maximum odor concentration. In the third deodorizing stage, the speed of the fan of the deodorizing component is controlled to work according to the second variation mode, so as to deodorize the gas in the toilet bowl with gradually decreasing odor concentration.

[0040] The method of the present invention, when the deodorization component starts the deodorization function, controls the fan speed in stages to accurately match the deodorization intensity with the rise and fall of the odor concentration in the toilet bowl, which can not only intervene in advance to suppress the spread of odor during the concentration climbing period, but also concentrate energy for efficient purification during the peak concentration period, and finally achieve full-cycle non-sensitive deodorization. In addition, progressive speed regulation is used instead of constant high-speed operation to avoid energy waste caused by continuous high-power output, while maintaining the core purification efficiency through stable speed during the peak period, and establishing a dynamic balance between noise reduction and deodorization efficiency.

[0041] In this embodiment, the first deodorization stage is aimed at the situation where the odor concentration is low and the odor concentration continues to increase over time. In this first stage, the speed of the fan works according to the first change mode, which specifically means: the fan is controlled to start at a speed corresponding to the first duty cycle, and the duty cycle is increased according to the set step length at every set time interval until the duty cycle reaches the set second duty cycle, and the first duty cycle is less than the second duty cycle. Among them, the speed of the fan is adjusted by adjusting the duty cycle. For example, when the duty cycle is 100%, it corresponds to the maximum speed of the fan, and the duty cycle of 50% corresponds to 50% of the maximum speed of the fan. Specifically, the first duty cycle is less than or equal to 50%, the second duty cycle is greater than 50% and less than or equal to 100%, the time interval is 5S-10S, and the step length is set to 10%.

[0042] In the first deodorization stage, as the fan continuously increases its speed, the amount of odor decomposition increases, achieving a rapid deodorization effect. The purpose is to maintain the necessary airflow disturbance intensity at this duty cycle, avoid ineffective energy consumption of full-speed operation, and increase the speed to the target speed more quickly. Among them, the fan speed is increased by a set value at every set time interval. The time interval and the increase setting value can be set according to the duration of the second deodorization stage, the first duty cycle and the second duty cycle, so that the speed increases at a uniform speed. For example, the deodorization fan uses 50% as the first duty cycle and 80% as the second duty cycle, and the time interval is 10s; then the duty cycle of the fan is controlled to start from 50%, increase to 60% after 10s, and then increase to 70% after 10s, and then increase to 80% after 10s.

[0043] In the second deodorization stage, the fan is controlled to operate at a speed corresponding to a duty cycle of not less than 80%. The second deodorization stage may be located after the first deodorization stage. In the first deodorization stage, when the duty cycle of the fan is increased to the second duty cycle, the first speed of the second deodorization stage is equal to the speed corresponding to the second duty cycle of the first deodorization stage. In practical applications, the duration of the second deodorization stage can be preset or set according to the duration of the maximum odor concentration.

[0044] The third deodorization stage is aimed at the situation where the odor concentration decreases over time. In the third stage, the speed of the fan works according to the second change mode, which specifically means: the fan is controlled to work at the speed corresponding to the second duty cycle, and the duty cycle is reduced according to the set step length at every set time interval until the duty cycle reaches the set third duty cycle, and the third duty cycle is less than the second duty cycle. Specifically, the second duty cycle is greater than 50% and less than or equal to 80%, the third duty cycle is less than or equal to 40%, the time interval is 5S-10S, and the set step length is 10%.

[0045] In the third deodorization stage, the odor concentration decreases, and the fan runs at a gradually decreasing speed, which is sufficient to meet the deodorization demand at this concentration. Among them, the fan speed is reduced by a set value at every set time interval. The time interval and the increase set value can be set as needed. For example, the deodorization fan first uses 80% duty cycle as the second duty cycle and 40% as the third duty cycle. The operation time interval is 10s, and the set step length is 10%. Then the duty cycle of the fan is controlled to start from 80%, and then decrease to 70% after 10s, and then decrease to 60% after 10s, and then decrease to 50% after 10s, and then decrease to 40% after 10s.

[0046] The speed of the fan is proportional to the noise. Take a certain fan as an example. Figure 8 , assuming that the noise corresponding to the maximum speed is 50dB, the noise corresponding to 80% of the maximum speed is 49dB, the noise corresponding to 70% of the maximum speed is 48dB, the noise corresponding to 60% of the maximum speed is 47dB, the noise corresponding to 50% of the maximum speed is 46dB, and the noise corresponding to 40% of the maximum speed is 45dB. With the solution of the present invention, the fan only runs at a short high speed in the second deodorization stage, and mainly at medium and low speeds in the remaining periods, which reduces the overall energy consumption, reduces the additional vibration noise caused by mechanical wear (the average noise drops to below 47dB), and prolongs the life of the equipment throughout the deodorization process, which is particularly suitable for noise-sensitive indoor scenes.

[0047] In the present invention, the odor concentration is continuously increasing, the odor concentration is at its maximum, and the odor concentration is gradually decreasing, etc., can be determined by comparing the concentration of ammonia or hydrogen sulfide in the air with a plurality of preset thresholds. Alternatively, the changing trend of the odor concentration can be indirectly inferred by combining the behavioral characteristics of the user using the toilet, for example, by using a pressure sensor to detect whether the user is in the process of using the toilet, and making a prejudgment based on behavioral data such as the duration of use. The judgment can also be achieved by combining the two methods.

[0048] Taking the detection of ammonia or hydrogen sulfide concentration as an example, the concentration of odor is judged by detecting the ammonia concentration or hydrogen sulfide concentration in the air in the toilet. When the detected ammonia concentration or hydrogen sulfide concentration gradually increases, the deodorization component is controlled to enter the first deodorization stage; when the detected ammonia concentration or hydrogen sulfide concentration is within the set threshold range, the deodorization component is controlled to enter the second deodorization stage; when the detected ammonia concentration or hydrogen sulfide concentration gradually decreases, the deodorization component is controlled to enter the third deodorization stage.

[0049] Taking the situation of a user using a toilet as an example, it is set that after the user sits down, the first deodorization stage, the second deodorization stage and the third deodorization stage are executed in chronological order, and the first deodorization stage is set to last for a first time length, the second deodorization stage lasts for a second time length, and the third deodorization stage lasts for a third time length.

[0050] Taking the combination of the two as an example, it is set that when the user sits down, the ammonia concentration or hydrogen sulfide concentration in the air in the toilet bowl is detected to determine the concentration of the odor. When the detected ammonia concentration or hydrogen sulfide concentration gradually increases, the deodorization component is controlled to enter the first deodorization stage. When the detected ammonia concentration or hydrogen sulfide concentration is within the set threshold range, the deodorization component is controlled to enter the second deodorization stage; when the detected ammonia concentration or hydrogen sulfide concentration gradually decreases, the deodorization component is controlled to enter the third deodorization stage.

[0051] Based on this, see Figure 2-Figure 7 The present invention also proposes a toilet deodorization control system, including a deodorization component 20 and a control unit. The deodorization component 20 is installed on the base 10 of the toilet and is provided with an air inlet 25 and an air outlet 26. The air inlet 25 faces the toilet bowl, so as to extract the air containing odor from the toilet bowl. The air outlet 26 faces outside the toilet bowl, and is used to discharge the deodorized air into the outside atmosphere. The control unit executes the above-mentioned toilet deodorization control method.

[0052] The base 10 of the toilet is arranged at the rear of the top surface of the ceramic body of the toilet, and a flushing assembly 30 is arranged on the base 10, and the flushing assembly 30 is used to perform functions such as buttocks washing or women washing. The deodorizing assembly 20 can be installed on the base 10 near the flushing assembly 30. The deodorizing assembly 20 includes a shell 21, a fan 22, and a deodorizing medium 27. The shell 21 is fixed to the base 10, and the shell 21 is provided with an air inlet duct 23 and an air outlet duct 24. The air inlet duct 23 is provided with an air inlet 25, and the air outlet duct 24 is provided with an air outlet 26. The deodorizing medium 27 is installed at the air outlet 26 of the air outlet duct 24, and the deodorizing medium 27 can be located at the bottom of the base 10. The deodorizing medium 27 can be a platinum catalyst or activated carbon, etc., and the platinum catalyst is taken as an example in the figure.

[0053] Furthermore, the size of the air inlet duct 23 is set to gradually increase along the air inlet direction from the air inlet 25 to the air inlet side of the fan 22. The air sucked into the air inlet duct 23 from the air inlet 25 is decelerated. After the air inlet section is decelerated, the fan 22 can maintain the target air volume of the air outlet duct 24 by adjusting the power, ensuring that the airflow on the air outlet side passes through the deodorizing medium 27 (such as photocatalyst, activated carbon) at a reasonable speed, guiding the airflow to evenly cover the surface of the deodorizing medium 27, and improving the medium utilization rate.

[0054] The system of the present invention also includes an ammonia sensor or a hydrogen sulfide sensor, which is installed on the base 10 to detect the ammonia concentration or hydrogen sulfide concentration in the air inlet duct 23 or the toilet bowl. For example, a ZEO3 sensor can be used to detect ammonia or hydrogen sulfide, which can convert the detected ammonia or hydrogen sulfide concentration into a voltage value output. The main control board of the toilet receives the voltage information, performs AD conversion to obtain the odor concentration, and controls the fan to perform deodorization according to the odor concentration.

[0055] The system of the present invention adopts the above-mentioned toilet deodorization control method. By adjusting the fan speed in stages, the deodorization intensity is accurately matched with the rising and falling changes of the odor concentration in the toilet bowl. Progressive speed adjustment is used instead of constant high-speed operation to establish a dynamic balance between noise reduction and deodorization efficiency.
