[0022] In order to further understand the content, characteristics and effects of the present application, the following examples are given below, and are described in detail as follows with reference to the accompanying drawings.

[0023] The application discloses a control method of a range hood with a purification function, please refer to Figure 1 and Figure 2 , the range hood comprises a main control module, an air quality detection module and a purification module, the main control module is a control module of the range hood, the main control module can obtain air quality data of a kitchen through the air quality detection module, and can control the working state of the air quality detection module; the main control module can control the working state of the purification module; the control method is characterized in that: the range hood has a learning mode, when the range hood is running, the main control module records time points at which the range hood is started by a user N times and time points at which the range hood is turned off corresponding to the time points, so as to obtain cooking time period preference information of the user, and forms a first preference time period T11, a second preference time period T12 and a third preference time period T13 according to the obtained cooking time period preference information, the first preference time period T11 corresponds to a breakfast cooking time period, the second preference time period T12 corresponds to a lunch cooking time period, and the third preference time period T13 corresponds to a dinner cooking time period; at a time point with a time length T from the start of each time period, the main control module starts the air quality detection module to detect air quality, if the air quality detected by the air quality detection module is not up to standard, the main control module starts the purification module to purify air in the kitchen; if the air quality detected by the air quality detection module is up to standard, the main control module makes the air quality detection module detect air quality once every waiting time t1, until entering the corresponding time period or the air quality is not up to standard, wherein t1

[0024] The control method of the range hood with the purification function of the present application, the main control module records the time points at which the range hood is started by the user each time and the shutdown time period corresponding to the time points, and obtains the cooking time period preference information of the user after recording N times, and forms the first preference time period T11 corresponding to the breakfast cooking time period, the second preference time period T12 corresponding to the lunch cooking time period and the third preference time period T13 corresponding to the dinner, and at a time point with a time length T from the start of each time period, the main control module starts the air quality detection module to detect air quality, and starts the purification module when the air quality is not up to standard, so that the purification module purifies the air in the kitchen in advance before the user enters the kitchen to cook, and the air quality in the kitchen meets the health standard when the user enters the kitchen to cook.

[0025] The control method of the range hood with the purification function of the present application, the first preference time period T11, the second preference time period T12 and the third preference time period T13 formed through the learning mode are time periods with high cooking frequency according to the habits of the user, and are targeted, so that the air quality in the kitchen can meet the standard when the user enters the kitchen to cook.

[0026] The control method of the range hood with the purification function of the present application, if the air quality detection module detects that the air quality meets the standard at the time point of T from the start of each time period, the air quality detection module detects the air quality once every waiting time t1, ensuring that the air quality in the kitchen meets the standard when the user enters the kitchen to start cooking. That is, when the air quality detection module detects that the air quality meets the standard at the time point of T from the start of each time period, the air quality detection module is closed and restarted to detect the air quality after waiting for time t1. If the air quality does not meet the standard, the purification module is started. If the air quality still meets the standard, the air quality detection module will be closed again and restarted to detect the air quality after waiting for time t1. This cycle continues until the time T ends, the time enters the corresponding cooking time period, or the air quality detection module detects that the air quality does not meet the standard.

[0027] The control method of the range hood with the purification function of the present application, when the purification module is started and purifies the air in the kitchen, the air quality detection module detects the air quality in real time until the air quality meets the standard, then the purification module is closed, and the air quality detection module is also closed and waits for the user to cook. Because the pollution of the air is not consistent every time when the purification module detects that the air quality does not meet the standard, the purification time of the purification module is not convenient to set. When the purification module is started and purifies the air, the air quality detection module detects the air quality in real time. When the air quality detection module detects that the air quality meets the standard, the main control module closes the purification module, and the air quality detection module can also be closed.

[0028] The control method of the range hood with the purification function of the present application, the air quality detection module can use a PM2.5 detection module to detect the concentration value or content of PM2.5 in the air. The main control module is set with the maximum PM2.5 concentration or PM2.5 content when the air quality meets the standard. When the PM2.5 detection module detects that the concentration value or content of PM2.5 in the air exceeds the standard and maintains for a certain period of time, the main control module starts the purification module to purify the air. During the purification process, the PM2.5 detection module monitors the PM2.5 concentration or PM2.5 content in the air. When the PM2.5 concentration or PM2.5 content in the air decreases to the standard value and maintains for a certain period of time, the main control module determines that the purification module has completed the purification work.

[0029] The control method of the range hood of the present application, if the purification module has completed the purification operation and the time has entered the preferred time period, the user still does not start the range hood, the main control module will make the air quality detection module detect the air quality once every waiting time t1, until the user starts the range hood, or the end of the corresponding time period. The logic set in the main control mode is to purify the kitchen air within T time before the user starts the cooking operation, but the time point of detecting the air quality is referred to the earliest time of the corresponding preferred time period, and in the preferred time period, the user has the possibility to perform the cooking operation, if the time interval between the time point when the user enters the cooking operation and the time point after the purification module completes the purification operation is greater than T, the kitchen air exists the condition of being polluted again in this period of time. Therefore, after the purification module has completed the purification operation and the time has entered the preferred time period, if the user still does not start the range hood, the main control module will make the air quality detection module detect the air quality once every waiting time t1, when the detected air quality meets the standard, the main control module makes the air quality detection module continue to wait for time t1 and then detects the air quality again, when the air quality does not meet the standard, the main control module makes the purification module start again and purifies the air, until the user starts the range hood, or the end of the corresponding time period.

[0030] That is, the control method of the range hood with purification function of the present application completes the air quality detection at the time point of T time from the start of each preferred time period, and after completing the air quality purification, the main control module is not a passive waiting for the user to enter the cooking operation, or waiting for the end of the corresponding preferred time period, but after the purification module has completed the purification operation and waits for time T, it is judged whether the user performs the cooking operation, and when the user does not perform the cooking operation in the corresponding preferred time period, the air quality detection module detects the air quality once every time t1, to ensure that when the user enters the kitchen in the corresponding preferred time period, the kitchen air quality meets the standard. When the corresponding preferred time period ends and the user still does not perform the cooking operation, the air quality detection module will be closed and stop detecting the air quality, to avoid overwork without practical significance.

[0031] The control method of the smoke machine with the purification function of the application, when the purification module is started and purifies the air in the kitchen, the air quality detection module detects the air quality in real time, until the air quality meets the standard, the purification module is closed, the air quality detection module is closed, and the user is waiting for cooking operation. This case corresponds to the case that the purification module has completed the purification operation and the time has entered the preferred time period, that is, at the time point of T from the start of each preferred time period, the air quality detection module detects that the air quality meets the standard, and in the process of detecting the air quality again, the air quality does not meet the standard, the purification module will enter the purification mode, and when the purification mode is entered from this case, the time from the corresponding preferred time period may be less than the time required for the purification module to complete the purification operation, so it may appear that the purification module has not completed the purification operation, and the corresponding preferred time period is over. If this situation occurs, if the user still does not start, the purification module completes the purification operation and is closed; and in the case that the user starts the smoke machine when the purification mode does not complete the purification operation, since the user has started the smoke machine, the exhaust fan of the smoke machine will suck the air in the kitchen, and the air in the kitchen will be replaced. In this case, the purification module is closed to make the smoke machine run normally.

[0032] The control method of the smoke machine with the purification function of the application, when the smoke machine is started, the air quality detection module is in the starting state and detects the air quality in real time. When the smoke machine is started, the user cooks, the air quality detection module detects the air quality and judges the suction effect of the smoke machine on the oil fume, when the air quality does not meet the standard, it means that the current running power of the smoke machine is not enough to make the smoke machine timely exhaust the oil fume from the kitchen, the user can automatically select to increase the running power of the smoke machine, or directly set the corresponding control mode in the main control mode, so that the main control module can adjust the running power of the smoke machine according to the air quality detected by the air quality detection module when the smoke machine runs. The most important thing is to increase the running power of the smoke machine when the air quality does not meet the standard.

[0033] The control method of the smoke machine with the purification function of the application, please refer to Figure 1 and Figure 2The smoke machine further comprises a WiFi module, the WiFi module is used for connecting a router of a user, the WiFi module can realize networking of the smoke machine, thereby obtaining local time and location and other related information, and can upload the state and data of the smoke machine to a server; after the WiFi module connects the router of the user, the main control module can identify the date information of the location of the user, and record the actual cooking time period of the user on the corresponding weekend date; after obtaining the cooking time period preference information of the user for M weekends, the first weekend preference time period T31, the second weekend preference time period T32 and the third weekend preference time period T33 for the weekend are formed, and the preference time period is taken as the basis, at the time point of a time length T from the start of each weekend preference time period, the main control module starts the air quality detection module to detect the air quality, if the air quality detected by the air quality detection module does not meet the standard, the main control module starts the purification module to purify the air in the kitchen; if the air quality detected by the air quality detection module meets the standard, the main control module makes the air quality detection module detect the air quality once every waiting time t1 until entering the corresponding time period or the air quality does not meet the standard, wherein t1

[0034] Please refer to Figure 1 and Figure 2The control method of the range hood with the purification function has an initial mode, in which the range hood has a first initial preferred time period T01, a second initial preferred time period T02 and a third initial preferred time period T03, at a time point with a time length of T from the start of each time period, the main control module starts the air quality detection module to detect the air quality, if the air quality detected by the air quality detection module is not up to the standard, the main control module starts the purification module to purify the air in the kitchen, if the air quality detected by the air quality detection module is up to the standard, the main control module makes the air quality detection module detect the air quality again after waiting for a time length of t1, until entering the corresponding time period, wherein t1

[0035] In the control method of the range hood with the purification function, in the learning mode, the main control module sequentially divides the first preferred time period T11 corresponding to the breakfast cooking time period into n1 first hour periods, sequentially divides the second preferred time period T12 corresponding to the lunch cooking time period into n2 second hour periods, sequentially divides the third preferred time period T13 corresponding to the dinner cooking time period into n3 third hour periods, and counts the frequency of the start of the range hood in each hour period, removes the small time period in the corresponding cooking time period that is earlier and has a low frequency of the start, removes the small time period in the corresponding cooking time period that is later and has a low frequency of the start, and obtains the first preferred time period T11, the second preferred time period T12 and the third preferred time period T13.

[0036] For example, the master module records the time point when a user starts the range hood N times and the time point when the range hood is turned off corresponding to the time point, obtains the initial value of the first preferred time period T11 corresponding to the breakfast cooking time period as 6:00-9:00, and divides the two hours of 6:00-9:00 into a first small time period every 10 minutes, a total of 18 small time periods, and each time period is in turn: 6:00-6:10, 6:10-6:20, 6:20-6:30, 6:30-6:40, 6:40-6:50, 6:50-7:00, 7:00-7:10, 7:10-7:20, 7:20-7:30, 7:30-7:40, 7:40-7:50, 7:50-8:00, 8:00-8:10, 8:10-8:20, 8:20-8:30, 8:30-8:40, 8:40-8:50, 8:50-9:00; it is assumed that the number of times the user starts the range hood in the first small time period of 6:00-6:10, 6:10-6:20, 8:40-8:50, and 8:50-9:00 is small, and the frequency in the breakfast time period is low, so the first small time period of 6:00-6:10, 6:10-6:20, 8:40-8:50, and 8:50-9:00 will be eliminated, and the master module will correct the first preferred time period T11 corresponding to the breakfast cooking time period as 6:20-8:40; and if the number of times the user starts the range hood in the first small time period of 6:00-6:10, 6:10-6:20, 8:40-8:50, and 8:50-9:00 is normal, the frequency in the breakfast time period is normal, and the number of times the range hood is started in other small time periods in the time period of 6:20-8:40 is low, the master module will not eliminate the small time period in the time period of 6:20-8:40.

[0037] The elimination method of the small time period of the second preferred time period T12 corresponding to the lunch cooking time period and the third preferred time period T13 corresponding to the dinner cooking time period is as above, and will not be repeated here.

[0038] The control method of the smoke machine with the purification function, the main control module of the smoke machine repeatedly learns, after completing a learning mode and forming the first preferred time period T11, the second preferred time period T12 and the third preferred time period T13, the smoke machine takes the corresponding preferred time period as the time basis of purifying air in advance, and meanwhile, when the user starts and stops the smoke machine each time, the main control module continues to record the time point of starting the smoke machine and the time point of stopping the smoke machine corresponding to the time point for the user's subsequent N times, forms a new preferred time period, and replaces the original preferred time period with the new preferred time period, so as to continuously adapt to the change of the user's cooking habit. For some users who need to go to work, the selection of the breakfast and dinner time period is greatly related to the working time, and there are summer time and winter time in the company, and the working time is different between the summer time and the winter time, so after the smoke machine completes a learning mode and forms the first preferred time period T11, the second preferred time period T12 and the third preferred time period T13, the smoke machine takes the corresponding preferred time period as the time basis of purifying air in advance, and in the subsequent cooking process, the main control module still records the time point of starting the smoke machine and the time point of stopping the smoke machine corresponding to the time point for the user's subsequent N times, forms a new preferred time period, and replaces the last preferred time period with the new preferred time period, so as to continuously adapt to the change of the user's cooking habit.

[0039] Please refer to Figure 1 and Figure 2The control method of the smoke machine with the purification function has the smoke machine further comprising a WiFi module, the WiFi module is used for connecting a router of a user, after the WiFi module connects the router of the user, a master control module can identify a location of the user; the smoke machine further has an adaptive mode, after the WiFi module connects the router of the user and the master control module identifies the location of the user and time information of the location, the master control module judges a common cooking habit of local users according to location information of the smoke machine, if a time period corresponding to the common cooking habit of the local users is greatly different from an initial time period set by an initial mode, the master control module forms a first debugging time period T21, a second debugging time period T22 and a third debugging time period T23 according to the time period corresponding to the common cooking habit of the local users, and at a time point with a time length of T before the start of each time period, the master control module starts an air quality detection module to detect air quality. The initial time set by the initial mode can be set according to Beijing time, and sunrise and sunset times are different in different regions, for example, in remote areas, the work and rest habits of residents are greatly different from the initial time set by the initial mode, and the smoke machine cannot ensure that the air quality of the kitchen space is up to standard before the user cooks according to the initial time period set by the initial mode. Therefore, after the smoke machine is installed in the user's home, the WiFi module of the smoke machine connects the router of the user, so that the master control module identifies the location of the user and the time information of the location, according to the location of the user, queries the sunrise and sunset times of the corresponding region, and analyzes the common cooking habit of the users in the corresponding region. The analysis of the common cooking habit of the users in the corresponding region is based on the sunrise and sunset times of the local area and the working hours of most enterprises in the local area; if the time period corresponding to the common cooking habit of the local users is greatly different from the initial time period set by the initial mode, the master control module forms the first debugging time period T21, the second debugging time period T22 and the third debugging time period T23 according to the time period corresponding to the common cooking habit of the local users, and takes the first debugging time period T21, the second debugging time period T22 and the third debugging time period T23 as the basis for the smoke machine to perform the purification operation in advance. When the smoke machine is initially used and the learning mode is not completed, the first initial preference time period T01, the second initial preference time period T02 and the third initial preference time period T03 are replaced by the first debugging time period T21, the second debugging time period T22 and the third debugging time period T23, so that the pre-purification function of the smoke machine can be effectively used as much as possible. Here, effective means that the pre-purification function effectively serves the user.

[0040] The control method of the smoke machine with the purification function of the application, when the main control module records the time point of the user starting the smoke machine N times and the time point of turning off the smoke machine corresponding to the time point, the smoke machine replaces the debugging time period formed by the main control module according to the general cooking habit of the user's location with the preferred time period formed by the learning mode. Although the smoke machine connects the user's router through the WiFi module, so that the main control module can identify the user's location and form the first debugging time period T21, the second debugging time period T22 and the third debugging time period T23, the first debugging time period T21, the second debugging time period T22 and the third debugging time period T23 and the first preferred time period T11, the second preferred time period T12 and the third preferred time period T13 of each user are still different, the first preferred time period T11, the second preferred time period T12 and the third preferred time period T13 of each user are obtained through the learning mode, and the preferred time period is used as the time basis of the advance purification of the purification module, so that the user can be better adapted, and the advance purification function can effectively serve the user.

Claims

1. A control method for a range hood with a purification function, the range hood comprising a main control module, an air quality detection module, and a purification module, characterized in that: The control method is as follows: the range hood has an initial mode and a learning mode. In the initial mode, the range hood has a first initial preferred time period T01, a second initial preferred time period T02, and a third initial preferred time period T03. At a time point T from the start of each time period, the main control module activates the air quality detection module to detect the air quality. If the air quality detected by the air quality detection module does not meet the standard, the main control module activates the purification module to purify the kitchen air. If the air quality detected by the air quality detection module meets the standard, the main control module makes the air quality detection module wait for a period of time t1 and then detect the air quality again until the corresponding time period is entered; the main control module records the time points of the user starting the range hood N times and the time points of shutting down the range hood corresponding to the time points, so as to obtain the user's cooking period preference information, and forms a first preference time period T11, a second preference time period T12 and a third preference time period T13 according to the obtained cooking period preference information. The first preference time period T11 corresponds to the breakfast cooking time period, the second preference time period T12 corresponds to the lunch cooking time period, and the third preference time period T13 corresponds to the cooking time period. The range hood uses the preferred time period formed by the learning mode to replace the time period set in the initial mode during the dinner cooking time period. At a time point T away from the start of each preferred time period, the main control module starts the air quality detection module to detect the air quality. If the air quality detected by the air quality detection module does not meet the standard, the main control module starts the purification module to purify the kitchen air. If the air quality detected by the air quality detection module meets the standard, the main control module enables the air quality detection module to detect the air quality once every waiting time t1 until entering the corresponding time period or the air quality does not meet the standard, where t1<T.

2. The control method of the range hood with purification function according to claim 1, characterized in that: The range hood also includes a WiFi module, which is used to connect to the user's router. After the WiFi module is connected to the user's router, the main control module can identify the date information of the user's location and record the user's actual cooking time period when the date corresponds to the weekend; after obtaining the user's M weekend cooking period preference information, a first weekend preference time period T31, a second weekend preference time period T32 and a third weekend preference time period T33 are formed for the weekend, and based on this preference time period, at a time point T away from the start of each weekend preference time period, the main control module starts the air quality detection module to detect the air quality. If the air quality detected by the air quality detection module does not meet the standard, the main control module starts the purification module to purify the kitchen air; if the air quality detected by the air quality detection module meets the standard, the main control module enables the air quality detection module to detect the air quality once every waiting time t1 until entering the corresponding time period or the air quality does not meet the standard, where t1<T.
