[0032] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be described in further detail below with reference to the drawings. It is hereby declared that the up, down, left, right, front, back, inner and outer directions appearing or about to appear in the present application are based on the drawings of the present application only, and are not specific limitations on the present application.

[0033] As shown in Figure 1 The present application provides a bathroom fresh air control method, comprising:

[0034] S101, obtaining a driving signal and driving the air exchange mechanism to operate in a segmented operation mode, and simultaneously obtaining a real-time temperature monitoring signal of the temperature monitoring mechanism;

[0035] S102, controlling the switching state of the heating mechanism according to the real-time temperature monitoring signal.

[0036] The segmented operation mode comprises a first operation period, a second operation period and a third operation period in sequence, in the first operation period, the air exchange mechanism is driven to operate at a first operation rate for a first time length, the first operation rate is a constant rate, in the second operation period, the air exchange mechanism is driven to operate at a second operation rate for a second time length, the second operation rate is a changing rate that decreases with time, in the third operation period, the air exchange mechanism is driven to operate at a third operation rate for a third time length, then the air exchange mechanism is closed and a voice prompt is issued, the third operation rate is a constant rate.

[0037] The present application can reduce the noise of exhaust during defecation by driving the air exchange mechanism to operate in a segmented operation mode, and can solve the discomfort during defecation in cold weather by controlling the switching of the heating mechanism according to the real-time temperature monitoring signal.

[0038] Specifically, after starting the bathroom fresh air function, the odor generated in the initial stage of defecation is the largest, so the air exchange mechanism will operate at a first operation rate (generally full speed, but not limited to this) for a first time length to exchange the air in the bathroom once, which is the first operation period; then the operation rate of the air exchange mechanism is slowly reduced according to time, this process will last for a second time length to exhaust the continuously generated odor from the bathroom, which is the second operation period; finally, the third operation rate (generally the rate of the lowest gear, but not limited to this) is operated for a third time length, which reduces the noise while slowly exchanging air, which is the third operation period; after the operation is completed, the air exchange is automatically closed, and the buzzer sounds three times, the purpose is to remind the user not to sit or squat for a long time during defecation.

[0039] Preferably, in the first operating period, the first duration satisfies: t1 = V / (ν1*a), where t1 is the first duration, V is the volume of the bathroom space, ν1 is the first operating rate, and a is the ventilation mechanism constant. Further, in the second operating period, the second duration satisfies: t2 = t 均 -t1, where t1 is the first duration, t 均 Let t be the average toilet time per person as a constant. 均 The value range is 5 minutes to 30 minutes.

[0040] It should be noted that in this embodiment, after calculating the volume V of the bathroom space based on the average area of ​​the average household bathroom per person, the time it takes for the air of volume V to be ventilated once through the current ventilation mechanism is defined as the first duration. The product of the first operating rate and the ventilation mechanism constant is the ventilation rate of the ventilation mechanism. Additionally, the average toilet time constant t is... 均 The difference between the first duration t0 and the second duration t1 is used as the second duration, where the value of t0 ranges from 5 minutes to 30 minutes, but is not limited to this. Therefore, through this embodiment, in the first part of the toilet time, the ventilation fan is driven to replace the air in the bathroom space at a higher first operating rate, and in the second part of the time, the continuously generated odor is discharged from the bathroom at a gradually decreasing rate, thereby reducing the noise of exhaust during toilet use.

[0041] More preferably, in the third running period, the third running rate satisfies: ν3 = ν1 / n, where n is a positive integer and the value of n ranges from 3 to 6; the third duration is a constant t representing the duration of discomfort from prolonged sitting. 久 , t 久 The value range is 10 minutes to 30 minutes.

[0042] It should be noted that in this embodiment, based on the current average toilet time per person, a third operating rate (preferably one-third to one-sixth of the first operating rate, but not limited to this) is used for a third duration. The third duration is based on the time when a person may feel uncomfortable after sitting for a long time and then getting up (preferably 10 to 30 minutes, but not limited to this). Therefore, it is equivalent to providing a prolonged sitting reminder based on the third duration. That is, when the third operating period ends, the ventilation mechanism is turned off and a prolonged sitting reminder is issued.

[0043] Preferably, the starting value of the second operating rate is consistent with the first operating rate, and the ending value of the second operating rate is consistent with the third operating rate. Preferably, the second operating rate satisfies: ν2 = ν1 - (ν1 - ν3) * t / t2, where ν2 is the second operating rate, ν1 is the first operating rate, ν3 is the third operating rate, t2 is the second duration, and t is a time variable.

[0044] It should be noted that in the embodiment, the starting value of the second operating rate is consistent with the first operating rate, the ending value of the second operating rate is consistent with the third operating rate, and the second operating rate is a linear function of time, but is not limited thereto. By using the embodiment, the air exchange mechanism can work at a continuous rate, avoiding noise and instability of the system caused by too large rate change.

[0045] As shown in Figure 2 Preferably, the step of controlling the switch of the heating mechanism according to the real-time temperature monitoring signal comprises:

[0046] S201, obtaining an initial monitoring temperature of the temperature monitoring mechanism,

[0047] S202, determining whether the initial monitoring temperature is greater than a first preset temperature. If yes, the heating mechanism is turned on for heating. If no, the heating mechanism is not turned on.

[0048] S203, obtaining a real-time heating monitoring temperature of the temperature monitoring mechanism during the heating process;

[0049] S204, determining whether the real-time heating monitoring temperature is greater than a second preset temperature. If yes, the heating mechanism is turned off. If no, the heating mechanism is kept in the on state.

[0050] S205, obtaining a real-time monitoring temperature of the temperature monitoring mechanism during the turning-off process;

[0051] S206, determining whether the real-time monitoring temperature is less than a third preset temperature, wherein the third preset temperature is greater than the first preset temperature and less than the second preset temperature. If yes, the heating mechanism is turned on again. If no, the heating mechanism is kept in the off state.

[0052] S207, when the air exchange mechanism is turned off, the heating mechanism is also turned off.

[0053] It should be noted that in the embodiment, when the new air for toilet is opened, the system collects the current environmental temperature as the initial monitoring temperature, so as to determine whether to open the heating mechanism. When the initial monitoring temperature is less than T1℃, the heating mechanism is automatically opened, so that the user will not feel cold when using the toilet. After the heating mechanism is opened, because there is a temperature difference between the temperature detection area of the temperature monitoring mechanism and the area where the human body is located (because the temperature monitoring mechanism is arranged on the heating mechanism, relatively speaking, when the heating mechanism is opened, the temperature monitored by the temperature monitoring mechanism is higher than the temperature of the area where the human body is located; in addition, at the beginning, because the heating mechanism is kept closed before, the air flow is sufficient, so the temperature monitored by the temperature monitoring mechanism is basically consistent with the temperature of the area where the human body is located), therefore, during the heating process, when the temperature monitored by the temperature monitoring mechanism is greater than T2℃, the heating mechanism is automatically closed, and during the closing process, when the temperature monitored by the temperature monitoring mechanism gradually decreases to T3℃ (wherein T1<T3<T2), the warm air is automatically opened again. This cycle continues until the new air for toilet is closed. By using the embodiment, the opening and closing of the heating mechanism can be controlled according to the real-time temperature monitoring signal, and the discomfort when using the toilet in cold weather is solved.

[0054] As Figure 3 shown, preferably, the bathroom new air control method further comprises:

[0055] S301, acquiring and identifying the identity information of the user;

[0056] S302, determining whether the user has set the first running rate, the first time length, the second time length, the third running rate and the third time length according to the identity information,

[0057] S303, if yes, driving the air exchange mechanism according to the corresponding first running rate, first time length, second time length, third running rate and third time length,

[0058] S304, if no, prompting the user to make self-defined setting or default setting.

[0059] It should be noted that in the embodiment, the identity information of the user is identified by the identity recognition mechanism (the identity recognition mechanism pre-stores the identity information of the user and the first running rate, the first time length, the second time length, the third running rate and the third time length corresponding to the identity information, that is, each user has different needs for heating temperature and air exchange speed), and the corresponding first running rate, first time length, second time length, third running rate and third time length are selected according to the corresponding identity information, so as to realize personalized automatic control and improve the convenience of use.

[0060] As Figure 4As shown, the application also provides a bathroom fresh air control device for implementing the bathroom fresh air control method, which comprises a ventilation mechanism 8, a heating mechanism 2, a temperature monitoring mechanism 1, a control mechanism 6 and a reminding mechanism 7, wherein the ventilation mechanism 8, the heating mechanism 2, the temperature monitoring mechanism 1 and the reminding mechanism 7 are electrically connected with the control mechanism 6; the ventilation mechanism 8 is used for inhaling external air and discharging indoor air; the heating mechanism 2 is used for heating indoor air; the temperature monitoring mechanism 1 is fixedly arranged on the heating mechanism 2 and is used for monitoring indoor environmental temperature; the reminding mechanism 7 is used for voice reminding a user at the end of the third operation period; and the control mechanism 6 is used for acquiring and controlling the heating mechanism 2 according to the real-time temperature monitoring signal, and is also used for driving and controlling the ventilation mechanism 8 to operate in a segmented operation mode, wherein the segmented operation mode comprises a first operation period, a second operation period and a third operation period in sequence, in the first operation period, the ventilation mechanism is driven to operate at a first operation speed for a first time length, the first operation speed is a constant speed, in the second operation period, the ventilation mechanism is driven to operate at a second operation speed for a second time length, the second operation speed is a changing speed which decreases with time, and in the third operation period, the ventilation mechanism is driven to operate at a third operation speed for a third time length, then the ventilation mechanism is closed and a voice prompt is given, and the third operation speed is a constant speed.

[0061] According to the application, by driving the ventilation mechanism to operate in the segmented operation mode, the noise of exhaust air during defecation can be reduced, and by controlling the heating mechanism according to the real-time temperature monitoring signal, the discomfort during defecation in cold weather can be solved. Specifically, after starting the bathroom fresh air function, because the odor generated in the initial stage of defecation is the largest, the ventilation mechanism operates at the first operation speed (generally full speed, but not limited to this) for the first time length, so that the air in the bathroom is replaced, which is the first operation period; then the operation speed of the ventilation mechanism is slowly reduced according to time, and this process lasts for the second time length, so that the continuously generated odor is discharged from the bathroom, which is the second operation period; finally, the ventilation mechanism operates at the third operation speed (generally the speed of the lowest gear, but not limited to this) for the third time length, so that the noise is reduced and the air is slowly replaced, which is the third operation period; after the operation is completed, the ventilation mechanism is automatically closed, and the buzzer rings three times, which aims to remind the user not to sit or squat for a long time during defecation.

[0062] Specifically, in the first operation period, the first time length satisfies t1=V / (v1*a), wherein t1 is the first time length, V is the volume of the bathroom space, v1 is the second operation speed, and a is a ventilation mechanism constant. In the second operation period, the second time length satisfies t2=t1 / (v2-v1), wherein t2 is the second time length, v2 is the first operation speed, and v1 is the second operation speed. In the third operation period, the third time length satisfies t3=t1 / (v3-v2), wherein t3 is the third time length, v3 is the third operation speed, and v2 is the second operation speed. 均t1, wherein t1 is the first time length, t0 is a per capita toilet time constant, and t0 is in the range of 5 minutes to 30 minutes. In the third operating period, the third operating speed satisfies: v3=v1 / n, wherein n is a positive integer, and n is in the range of 3 to 6; and the third time length is a constant of a sitting discomfort time t 久 , t 久 is in the range of 10 minutes to 30 minutes. The starting value of the second operating speed is consistent with the first operating speed, and the ending value of the second operating speed is consistent with the third operating speed. The second operating speed satisfies: v2=v1-(v1-v3)*t / t2, wherein v2 is the second operating speed, v1 is the first operating speed, v3 is the third operating speed, t2 is the second time length, and t is a time variable.

[0063] It should be noted that, according to the average area of the current per capita family toilet, the volume V of the bathroom space is calculated, and the time for the air of the volume V to be exhausted by the current air exchange mechanism for one time of air exchange is the first time length, wherein the product of the first operating speed and the air exchange mechanism constant is the air volume exhaust air exchange speed of the air exchange mechanism. In addition, the difference between the per capita toilet time constant t 均 and the first time length t1 is the second time length, wherein t0 is in the range of 5 minutes to 30 minutes, but is not limited thereto; therefore, in the early stage of the toilet time, the air exchange mechanism is driven to exchange the air in the bathroom space at a high first operating speed for one time, and in the later stage, the continuously generated odor is discharged from the toilet at a gradually decreasing speed, thereby reducing the noise of the exhaust during the toilet. In addition, on the basis of the current per capita toilet time, the third operating speed (preferably one third to one sixth of the first operating speed, but not limited thereto) is operated for a third time length, and the third time length is according to the time (preferably 10 minutes to 30 minutes, but not limited thereto) that the human body may feel uncomfortable after sitting for a long time, and therefore corresponds to the sitting reminder according to the third time length, that is, when the third operating period ends, the air exchange mechanism is closed, and the sitting reminder is performed. At the same time, the starting value of the second operating speed is consistent with the first operating speed, the ending value of the second operating speed is consistent with the third operating speed, and the second operating speed is a linear function of time, but is not limited thereto; the air exchange mechanism can be operated at a continuous speed, thereby avoiding the noise and instability of the system caused by the large change in the speed.

[0064] In addition, the switch step of the heating mechanism: obtaining the initial monitoring temperature of the temperature monitoring mechanism; determining whether the initial monitoring temperature is greater than a first preset temperature, and if yes, turning on the heating mechanism to heat, and if no, not turning on the heating mechanism; in the heating process, obtaining the real-time heating monitoring temperature of the temperature detection mechanism; determining whether the real-time heating monitoring temperature is greater than a second preset temperature, and if yes, turning off the heating mechanism, and if no, maintaining the on state of the heating mechanism; in the closing process, obtaining the real-time monitoring temperature of the temperature detection mechanism; determining whether the real-time monitoring temperature is less than a third preset temperature, wherein the third preset temperature is greater than the first preset temperature and less than the second preset temperature, and if yes, re-turning on the heating mechanism, and if no, maintaining the off state of the heating mechanism; when the air exchange mechanism is closed, the heating mechanism is also closed.

[0065] It should be noted that in the present embodiment, when the toilet fresh air is turned on, the system collects the current ambient temperature as the initial monitoring temperature to determine whether to turn on the heating mechanism. When the initial monitoring temperature is less than T1℃, the heating mechanism is automatically turned on, so that the user will not feel cold when using the toilet. After the heating mechanism is turned on, there is a temperature difference between the temperature detection area of the temperature monitoring mechanism and the area where the human body is located (because the temperature monitoring mechanism is arranged on the heating mechanism, and relatively speaking, when the heating mechanism is turned on, the temperature monitored by the temperature monitoring mechanism is higher than the temperature of the area where the human body is located due to insufficient air flow. In addition, at the beginning, the heating mechanism is kept in the off state, and the air flow is sufficient, so that the temperature monitored by the temperature monitoring mechanism is basically consistent with the temperature of the area where the human body is located). Therefore, during the heating process, when the temperature monitored by the temperature monitoring mechanism is greater than T2℃, the heating mechanism is automatically turned off, and during the closing process, when the temperature monitored by the temperature monitoring mechanism gradually decreases to T3℃ (wherein T1<T3<T2), the heating mechanism is automatically turned on again. This cycle continues until the toilet fresh air is turned off. By using the present embodiment, the heating mechanism can be controlled according to the real-time temperature monitoring signal, and the discomfort of using the toilet in cold weather is solved.

[0066] As shown in Figure 5 The bathroom fresh air control device further comprises an identity recognition mechanism 10 for obtaining and recognizing the identity information of the user and being electrically connected with the control mechanism 6. Further, the identity recognition mechanism is a face recognition mechanism or a fingerprint recognition mechanism.

[0067] It should be noted that the identity recognition mechanism 10 acquires and identifies the identity information of the user, and the control mechanism judges whether the user has set the first running speed, the first time length, the second time length, the third running speed and the third time length according to the identity information, judges that it is, and drives the air exchange mechanism according to the corresponding first running speed, first time length, second time length, third running speed and third time length, judges that it is not, and prompts the user to perform custom setting or default setting; It should be noted that in the embodiment, the identity information of the user is identified by the identity recognition mechanism (the identity recognition mechanism pre-stores the identity information of the user and the heating temperature and air exchange speed corresponding to the identity information, that is, each user has different needs for the heating temperature and air exchange speed), and the corresponding heating temperature and air exchange speed are selected according to the corresponding identity information, realizing personalized automatic control and improving the convenience of use.
