[0029] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme 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 described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

It should be understood that the data 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.

[0031] Figure 1 This is a flow chart of a range hood control method provided by an embodiment of the present invention. The method can be executed by a range hood control device. The range hood control device can be implemented in the form of hardware and / or software. The range hood control device can be configured in the range hood. Figure 1 As shown, the method may specifically include the following steps:

[0032] S101, obtaining the total amount of oil smoke generated by the stove below the range hood.

[0033] The total amount of oil smoke can be understood as the total number of oil smoke particles generated when the user uses the stove under the range hood to cook. Figure 2 As shown, the range hood 20 may include an oil fume particle detector 201, which can be used to detect oil fume particles in the smoke collecting chamber of the range hood to obtain the total amount of oil fume generated by the stove below the range hood. In this way, the total amount of oil fume generated by the stove below the range hood can be determined based on the detected oil fume particles in the smoke collecting chamber.

[0034] In an optional embodiment, a fume particle detector can be used to detect the fume particles in the smoke collection area of ​​the smoke collecting chamber to obtain the total number of fume particles in the smoke collecting chamber, and then the total number of fume particles in the smoke collecting chamber is determined as the total amount of fume generated by the stove under the range hood.

[0035] For example, the oil smoke particle detector may be a particle scanner, which may be installed in the smoke collecting area of ​​the smoke collecting chamber; the particle scanner may be used to detect Figure 3 The oil fume particles in the smoke collecting area of ​​the smoke collecting chamber are obtained to obtain the total number of oil fume particles in the smoke collecting chamber, and then the total number of oil fume particles in the smoke collecting chamber is determined as the total amount of oil fume A generated by the stove under the range hood.

[0036] S102, obtaining the concentration of unsettled oil fume not deposited inside the range hood, and determining the total amount of unsettled oil fume not accumulated inside the range hood according to the concentration of unsettled oil fume.

[0037] The concentration of unsettled oil smoke can be understood as the concentration of oil smoke that has not been precipitated on the range hood; the total amount of unsettled oil smoke can be understood as the total amount of oil smoke particles that have not been precipitated on the range hood; Figure 2 As shown, the range hood 20 may further include a fume concentration detector 202. The fume concentration detector 202 may be used to detect fume particles in the fume collecting chamber to obtain the concentration of unsettled fume that has not settled inside the range hood.

[0038] In an optional embodiment, an oil fume concentration detector can be used to detect the oil fume particles in the smoke collecting chamber to obtain the concentration of unsettled oil fume that has not been settled inside the range hood, and the total amount of unsettled oil fume that has not accumulated inside the range hood can be determined based on the unsettled oil fume concentration, which is equivalent to quantifying the oil fume particles to obtain the total amount of oil fume generated by the stove under the range hood and the total amount of unsettled oil fume that has not been settled on the range hood, and then a more accurate amount of precipitated oil fume is obtained based on the total amount of oil fume and the total amount of unsettled oil fume, and when the amount of precipitated oil fume and the cumulative working time of the range hood meet preset conditions, an oil cleaning reminder is given in time to improve the accuracy of the oil cleaning reminder of the range hood, so that the user can clean the oil fume deposited on the range hood in time according to the oil cleaning reminder, thereby increasing the intelligence and convenience of the range hood and bringing a better user experience to the user.

[0039] For example, the oil fume concentration detector can be a light sensor, and the transmitting end of the light sensor can be used to emit infrared light waves. The infrared light waves are scattered after irradiating the oil fume particles at the flue outlet. The receiving end of the light sensor receives the scattered light to obtain the amount of light, and then determines the unsettled oil fume concentration c that has not been settled inside the range hood based on the amount of light. Finally, the total amount of unsettled oil fume that has not accumulated inside the range hood is determined based on the unsettled oil fume concentration.

[0040] S103, determining the amount of precipitated oil fume precipitated inside the range hood according to the total amount of oil fume and the total amount of unprecipitated oil fume.

[0041] The amount of precipitated oil smoke can be understood as the total number of particles of oil smoke precipitated on the range hood.

[0042] In an optional embodiment, the difference between the total amount of oil fume and the total amount of unsettled oil fume is calculated to obtain the amount of settled oil fume settled inside the range hood. In this way, a more accurate amount of settled oil fume can be obtained based on the total amount of oil fume and the total amount of unsettled oil fume. When the amount of settled oil fume and the cumulative working time of the range hood meet preset conditions, an oil cleaning reminder is given in time to improve the accuracy of the oil cleaning reminder of the range hood, so that the user can clean the oil fume settled on the range hood in time according to the oil cleaning reminder, avoiding the range hood's exhaust effect being affected by excessive amount of settled oil fume, improving the exhaust effect of the range hood, increasing the intelligence and convenience of the range hood, and bringing a better user experience to the user.

[0043] For example, the total amount of oil fume is A, the total amount of unsettled oil fume is B, and the amount of settled oil fume is C. Then the total amount of oil fume A-the total amount of unsettled oil fume B=the amount of settled oil fume C.

[0044] S104, when the amount of precipitated oil smoke and / or the accumulated working time of the range hood meets the preset conditions, an oil cleaning prompt is given.

[0045] Among them, the cumulative working time can be understood as the total usage time from the start of using the range hood to the current time.

[0046] In an optional embodiment, when the amount of deposited oil fume exceeds a preset amount of deposited oil fume and the cumulative working time of the range hood exceeds a preset time, the power button flashes in real time to give an oil cleaning prompt, so that the user can clean the oil fume deposited on the range hood in time, avoid the range hood being affected by the excessive amount of deposited oil fume, improve the exhaust effect of the range hood, increase the intelligence and convenience of the range hood, bring a better user experience to the user, and increase the intelligence and convenience of the range hood; in addition, when the range hood has not been used for a long time and the amount of deposited oil fume exceeds the preset amount of deposited oil fume, the range hood may not be prompted to clean the oil because the cumulative working time is short and the amount of deposited oil fume is not enough to affect the normal operation of the range hood, saving the user's time for oil cleaning, increasing the intelligence and convenience of the range hood, and bringing a better range hood usage experience to the user. The preset duration can be understood as a preset critical value of the accumulated working time.

[0047] For example, the amount of deposited oil fume is C, the preset amount of deposited oil fume is c, the cumulative working time is T, and the preset time is t; when C>c and T>t, the power button flashes to remind the user to clean the oil stains; when the user notices that the power button is flashing, the oil fume deposited on the range hood can be cleaned in time to avoid excessive oil fume deposited on the range hood affecting the normal use of the range hood (for example, excessive oil fume deposited on the smoke collecting chamber will affect the smoke collecting effect of the smoke collecting chamber), thereby increasing the intelligence and convenience of the range hood and giving users a better experience of using the range hood.

[0048] In this embodiment, the total amount of oil fume generated by the stove below the range hood is obtained; the concentration of unsettled oil fume that has not been deposited inside the range hood is obtained, and the total amount of unsettled oil fume that has not accumulated inside the range hood is determined according to the concentration of unsettled oil fume; the amount of settled oil fume deposited inside the range hood is determined according to the total amount of oil fume and the total amount of unsettled oil fume, which is equivalent to quantifying the oil fume particles to obtain the total amount of oil fume generated by the stove below the range hood and the total amount of unsettled oil fume that has not been deposited on the range hood, and then a more accurate amount of settled oil fume is obtained according to the total amount of oil fume and the total amount of unsettled oil fume, and when the amount of settled oil fume and the accumulated working time of the range hood meet the preset conditions, an oil cleaning prompt is given in time to improve the accuracy of the oil cleaning prompt of the range hood, so that the user can clean the oil fume deposited on the range hood in time according to the oil cleaning prompt, avoid affecting the exhaust effect of the range hood due to excessive amount of settled oil fume, improve the exhaust effect of the range hood, increase the intelligence and convenience of the range hood, and bring a better user experience to the user.

[0049] Figure 4 Another flow chart of the control method of the range hood provided by the embodiment of the present invention is shown in FIG. Figure 4 As shown, the method may include the following steps:

[0050] S301, using an oil fume particle detector to detect oil fume particles in a smoke collecting chamber of the range hood to obtain a total amount of oil fume generated by a stove below the range hood.

[0051] S302, using an oil fume concentration detector to detect oil fume particles in the smoke collecting chamber to obtain the concentration of unsettled oil fume that has not been precipitated inside the range hood.

[0052] Among them, the oil fume concentration detector may include a first oil fume concentration detector and a second oil fume concentration detector. The first oil fume concentration detector can be installed at the flue outlet of the range hood, and the first oil fume concentration detector can be used to detect the oil fume particles at the flue outlet of the range hood to obtain the flue exhaust oil fume concentration of the flue outlet; the second oil fume concentration detector can be installed outside the smoke collecting chamber, and the second oil fume concentration detector can be used to detect the oil fume particles outside the smoke collecting chamber of the range hood to obtain the escape oil fume concentration outside the smoke collecting chamber; the unprecipitated oil fume concentration may include the flue exhaust oil fume concentration and the escape oil fume concentration outside the smoke collecting chamber, and the flue exhaust oil fume concentration can be understood as the concentration of the oil fume at the flue outlet; the escape oil fume concentration can be understood as the concentration of the oil fume escaping from the top of the stove to the surrounding of the smoke collecting chamber.

[0053] In an optional embodiment, a first oil fume concentration detector is used to detect oil fume particles at the flue outlet of the range hood to obtain the flue exhaust oil fume concentration at the flue outlet; a second oil fume concentration detector is used to detect oil fume particles outside the smoke collecting chamber of the range hood to obtain the escape oil fume concentration outside the smoke collecting chamber.

[0054] For example, the first oil fume concentration detector may be a light sensor, which may be installed at the flue air outlet of the range hood; the second oil fume concentration detector may be a gas sensor, which may be installed at Figure 3around the smoke collecting chamber in the smoke collecting chamber; using the transmitting end of the light sensor to emit infrared light waves, the infrared light waves are scattered after irradiating the smoke particles at the flue outlet, and the receiving end of the light sensor receives the scattered light to obtain the number of lights, and then query the preset information according to the number of lights to obtain the flue exhaust fume concentration c1 of the flue outlet, and the preset information includes the flue exhaust fume concentrations of the flue outlet corresponding to each number of lights; using the gas sensor to detect the escaped oil smoke around the smoke collecting chamber respectively to obtain the first escaped oil fume concentration, the second escaped oil fume concentration, the third escaped oil fume concentration and the fourth escaped oil fume concentration around the outside of the smoke collecting chamber, and then calculate the concentration averages of the first escaped oil fume concentration, the second escaped oil fume concentration, the third escaped oil fume concentration and the fourth escaped oil fume concentration to obtain the escaped oil fume concentration c2 outside the smoke collecting chamber.

[0055] S303: determining the total amount of unsettled oil fume that has not accumulated inside the range hood according to the unsettled oil fume concentration.

[0056] In an optional embodiment, the concentration of oil fumes discharged from the flue is multiplied by the outlet area of ​​the flue outlet to obtain the total amount of oil fumes discharged from the flue; the concentration of escaping oil fumes outside the smoke collecting chamber is multiplied by a preset adjustment coefficient to obtain the total amount of oil fumes escaping outside the smoke collecting chamber; based on the total amount of oil fumes discharged from the flue and the total amount of oil fumes escaping outside the smoke collecting chamber, the total amount of unsettled oil fume not accumulated inside the range hood is determined.

[0057] Specifically, the oil smoke discharged from the flue and the escaped oil smoke are both the oil smoke that has not settled on the range hood, so the sum of the total amount of oil smoke discharged from the flue and the total amount of oil smoke that escapes is the total amount of unsettled oil smoke that has not settled on the range hood. Therefore, in an optional embodiment, the total amount of oil smoke discharged from the flue and the total amount of oil smoke that escapes outside the smoke collecting chamber are added to obtain the total amount of unsettled oil smoke that has not accumulated inside the range hood. In this way, the total amount of unsettled oil smoke that has not accumulated inside the range hood can be more accurately determined, and then the amount of settled oil smoke can be determined based on the total amount of unsettled oil smoke and the total amount of oil smoke. Therefore, based on the amount of settled oil smoke and the accumulated working hours of the range hood, it can be more accurately determined whether to perform an oil cleaning prompt. When it is determined to perform an oil cleaning prompt, the power button flashes to prompt the user to clean the oil smoke deposited on the range hood in time, so as to avoid the range hood being affected by the excessive amount of settled oil smoke. The exhaust effect of the range hood is improved, the intelligence and convenience of the range hood are increased, and a better user experience is brought to the user.

[0058] For example, the first oil fume concentration detector can be a light sensor, which uses the transmitting end of the light sensor to emit infrared light waves. The infrared light waves are scattered after irradiating the oil fume particles at the flue outlet. The receiving end of the light sensor receives the scattered light and obtains the number of lights. Then, according to the number of lights, the preset information is queried to obtain the flue exhaust oil fume concentration c1 of the flue outlet. The preset information may include the flue exhaust oil fume concentrations of the flue outlet corresponding to each number of lights; the gas sensor is used to detect the escaped oil fume around the smoke collecting chamber to obtain the escaped oil fume concentration c2 outside the smoke collecting chamber; the flue exhaust oil fume concentration c1 is multiplied by the outlet area S of the flue outlet to obtain the total amount of flue exhaust oil fume b1; the escaped oil fume concentration c2 outside the smoke collecting chamber is multiplied by the preset adjustment coefficient w to obtain the total amount of escaped oil fume b2 outside the smoke collecting chamber; the total amount of unsettled oil fume B=the total amount of flue exhaust oil fume b1+the total amount of escaped oil fume b2.

[0059] In the present embodiment, an oil fume particle detector is used to detect the oil fume particles in the smoke collecting chamber of the range hood to obtain the total amount of oil fume generated by the stove below the range hood, a first oil fume concentration detector is used to detect the oil fume particles at the flue air outlet of the range hood to obtain the flue exhaust oil fume concentration of the flue air outlet, a second oil fume concentration detector is used to detect the oil fume particles outside the smoke collecting chamber of the range hood to obtain the escape oil fume concentration outside the smoke collecting chamber, the escape oil fume concentration outside the smoke collecting chamber is multiplied by a preset adjustment coefficient to obtain the total amount of oil fume escaped outside the smoke collecting chamber, the flue exhaust oil fume concentration is multiplied by the air outlet area of ​​the flue air outlet to obtain the total amount of oil fume exhausted from the flue, thereby improving the accuracy of the total amount of oil fume exhausted from the flue, and thus improving the efficiency of the control of the oil fume exhaust from the flue. The accuracy of the total amount of precipitated oil fume is equivalent to quantifying the oil fume particles to obtain the total amount of oil fume generated by the stove under the range hood and the total amount of unprecipitated oil fume that has not been deposited on the range hood, and then obtain a more accurate amount of precipitated oil fume based on the total amount of oil fume and the total amount of unprecipitated oil fume, and when the amount of precipitated oil fume and the cumulative working time of the range hood meet the preset conditions, timely oil cleaning reminders are given to improve the accuracy of the oil cleaning reminders of the range hood, so that users can clean the oil fume deposited on the range hood in time according to the oil cleaning reminder, avoid the range hood The exhaust effect of the range hood is affected by the excessive amount of precipitated oil fume, improve the exhaust effect of the range hood, increase the intelligence and convenience of the range hood, and bring users a better user experience.

[0060] S304, calculating the difference between the total amount of oil fume and the total amount of unsettled oil fume to obtain the amount of settled oil fume settled inside the range hood.

[0061] S305, when the amount of oily smoke deposited exceeds a preset amount of oily smoke deposited and the accumulated working time exceeds a preset time, the power button flashes to provide an oily cleaning prompt.

[0062] In some embodiments, an oil stain cleaning reminder message is generated after a preset waiting time, and the oil stain cleaning reminder message is sent to a terminal device bound to the range hood, so that a user of the terminal device can clean the oil stains deposited inside the range hood according to the oil stain cleaning reminder message. In this way, when the user does not notice that the power button is flashing, the terminal device can promptly remind the user to clean the oil stains deposited inside the range hood, so that the user can clean the oil smoke deposited on the range hood in time, avoiding the range hood's exhaust effect being affected by excessive amount of deposited oil smoke, improving the range hood's exhaust effect, increasing the intelligence and convenience of the range hood, and bringing a better user experience to the user.

[0063] For example, the preset waiting time is 3 minutes. After flashing the power button, wait for 3 minutes, then generate an oil cleaning reminder message, and send the oil cleaning reminder message to the terminal device (mobile phone) bound to the range hood, so that the user of the terminal device can clean the oil deposited inside the range hood according to the oil cleaning reminder message.

[0064] In this embodiment, the total amount of oil fume generated by the stove below the range hood is obtained; the concentration of unsettled oil fume that has not been deposited inside the range hood is obtained, and the total amount of unsettled oil fume that has not accumulated inside the range hood is determined according to the concentration of unsettled oil fume; the amount of settled oil fume deposited inside the range hood is determined according to the total amount of oil fume and the total amount of unsettled oil fume, which is equivalent to quantifying the oil fume particles to obtain the total amount of oil fume generated by the stove below the range hood and the total amount of unsettled oil fume that has not been deposited on the range hood, and then a more accurate amount of settled oil fume is obtained according to the total amount of oil fume and the total amount of unsettled oil fume, and when the amount of settled oil fume and the accumulated working time of the range hood meet the preset conditions, an oil cleaning prompt is given in time to improve the accuracy of the oil cleaning prompt of the range hood, so that the user can clean the oil fume deposited on the range hood in time according to the oil cleaning prompt, avoid affecting the exhaust effect of the range hood due to excessive amount of settled oil fume, improve the exhaust effect of the range hood, increase the intelligence and convenience of the range hood, and bring a better user experience to the user.
