[0056] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0057] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture.

In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0059] The operating status of existing range hoods 10 is typically displayed on a control panel or light. The icons on the control panel are often complex and difficult to read, or the text is too small to be clearly seen, making it difficult for users to understand the operating status of the range hood 10. The light, on the other hand, relies on manual operation to turn it on and off, providing only a conventional lighting function and preventing users from being able to monitor the operating status of the range hood 10 in real time.

[0060] In order to solve the above problems, the present invention proposes a range hood control method, which aims to allow the user to perceive the working status of the range hood 10.

[0061] Reference Figure 1 、 Figure 8 、 Figure 9 and Figure 10 In one embodiment of the present invention, the range hood 10 is used in conjunction with a stove 20. The range hood 10 includes a fan assembly 11 and a light-emitting assembly 12. The method includes the following steps:

[0062] S10, upon receiving a linkage signal output by the cooker, determining an operating mode of the range hood according to the linkage signal; the operating mode of the range hood includes an operating mode and a shutdown mode;

[0063] S20, when it is determined that the working mode is the operation mode, controlling the fan assembly to operate, and controlling the brightness of the light-emitting assembly to adjust from the first light-emitting mode to the second light-emitting mode;

[0064] S30. When it is determined that the working mode is the shutdown mode, the fan component is controlled to stop working, and the brightness of the light-emitting component is controlled to be adjusted from the second light-emitting mode to the first light-emitting mode.

[0065] It will be appreciated that the range hood control method of this embodiment is applied to the range hood 10. Alternatively, the range hood 10 can be a side-mounted range hood 10, or any other lighted range hood platform, such as a top-mounted or dual-mounted range hood, without limitation. The range hood 10 is designed to operate in conjunction with the stove 20. In practice, the control device 13 of the range hood 10 establishes a communication connection with the control component 21 of the stove 20. Specifically, this communication connection can be established via a 433 MHz communication component 15. Of course, other communication methods are possible between the range hood 10 and the stove 20, which will not be elaborated upon here. This configuration automatically turns the range hood 10 on when the stove 20 is turned on and automatically turns off the smoke when the stove 20 is turned off. This reduces the possibility of igniting the stove 20 without turning on the range hood 10, thereby improving user safety during cooking.

[0066] In this embodiment, the range hood 10 includes a fan assembly 11 and a light emitting assembly 12. The fan assembly 11 can be implemented by a baffle-type centrifugal fan, a mixed-flow centrifugal fan, a centrifugal fan or an axial-flow fan, and is mainly used to discharge the smoke generated by the range hood 10 when in operation, so as to avoid the growth of bacteria indoors and the impact on human health. The light emitting assembly 12 can be implemented by a narrow strip light, a square light, a round light or a light of other shapes, and its size is not specifically limited. The installation position of the light emitting assembly 12 on the range hood 10 can be at the top of the range hood 10, irradiating in the direction of the ground, or irradiating in the direction away from the wall, or irradiating in the front and lower part of the range hood 10, and there is no specific limitation here. The light-emitting component 12 is used to automatically turn on when the range hood 10 is turned on, and emit light to represent the working status of the range hood 10, and is used to automatically turn off when the range hood 10 is turned off. That is, when the stove 20 and the range hood 10 are used in conjunction, the stove 20 conveys status information such as operation and shutdown to the range hood 10, and the light color and dynamics of the light-emitting component 12 are displayed. The user does not need to check the icons and text lights on the control panel to more intuitively feedback the working status of the range hood 10.

[0067] Based on the above, in actual use, the range hood 10 receives the linkage signal output by the cooktop 20 in real time. Upon receiving the linkage signal, the range hood 10 determines its operating mode based on the linkage signal. The operating modes of the range hood 10 may include, but are not limited to, an operating mode and an off mode. The operating mode and off mode are set based on the operating state of the range hood 10. Specifically, the operating mode is the mode in which the range hood 10 is in operation, and the off mode is the mode in which the range hood 10 is in an off state. Optionally, this embodiment primarily categorizes the operating modes of the range hood 10 into the operating mode and the off mode. In other embodiments, more modes may be set based on the operating state of the range hood 10, and these will not be elaborated upon here.

[0068] Furthermore, when the range hood 10 determines that the working mode is the operating mode, the range hood 10 controls the fan assembly 11 to work to discharge the smoke generated by the user during the cooking process, and controls the light-emitting assembly 12 to adjust from the first light-emitting mode to the second light-emitting mode. It should be noted that the first light-emitting mode is to control the light-emitting assembly 12 to gradually switch between the first brightness and the second brightness; the second light-emitting mode is to control the light-emitting assembly 12 to gradually switch between the second brightness and the third brightness. In this embodiment, the first brightness is 0%, the second brightness is 80%, and the third brightness is the maximum brightness of the light-emitting assembly 12, specifically 100%. When the range hood 10 is started, the light of the light-emitting assembly 12 slowly brightens from the first light-emitting mode to the second light-emitting mode until it is fully lit. During this period, the light is dynamically displayed, which allows the user to intuitively understand the operating status of the range hood 10.

[0069] Similarly, when the range hood 10 determines that the operating mode is shutdown mode, it controls the fan assembly 11 to stop operating and controls the light-emitting assembly 12 to adjust from the second lighting mode to the first lighting mode. In this embodiment, when the range hood 10 is turned off, the light of the light-emitting assembly 12 gradually dims from the second lighting mode to the first lighting mode until the light is completely extinguished. During this period, the light is also dynamically displayed, which also facilitates the user to intuitively understand the shutdown status of the range hood 10.

[0070] The technical solution of the present invention comprises a range hood control method, a control device 13, a range hood 10, and a range hood-stove linkage system. The range hood 10 is configured to operate in conjunction with a stove 20 and includes a fan assembly 11 and a light assembly 12. The method comprises the following steps: upon receiving a linkage signal output by the stove 20, determining an operating mode of the range hood 10 based on the linkage signal; the operating modes of the range hood 10 include an operating mode and a shutdown mode; when the operating mode is determined to be the operating mode, controlling the fan assembly 11 to operate and adjusting the brightness of the light assembly 12 from a first lighting mode to a second lighting mode; and when the operating mode is determined to be the shutdown mode, controlling the fan assembly 11 to stop operating and adjusting the brightness of the light assembly 12 from the second lighting mode to the first lighting mode. The technical solution of the present invention utilizes the range hood linkage technology to transmit operating status information, such as operating and shutdown, from the stove 20 to the range hood 10. This information is displayed to the user through the color and dynamics of the light assembly 12 of the range hood 10, allowing the user to perceive the operating status of the range hood 10 in real time. Moreover, since the present invention uses the smoke and stove linkage technology to complete the control of the range hood 10 and senses the working status of the range hood 10 through the light of the light-emitting component 12, the control panel on the exterior surface of the range hood 10 can be removed during the actual design, thereby improving the appearance of the range hood 10 and allowing the range hood 10 to be better integrated into the home environment.

[0071] Reference Figure 2 、 Figure 8 and Figure 9 In one embodiment of the present invention, the linkage signal includes a running signal and a shutdown signal; and determining the working mode of the range hood 10 according to the linkage signal includes:

[0072] S11, when it is determined that the linkage signal is a running signal, determining that the working mode of the range hood is a running mode;

[0073] S12: When it is determined that the linkage signal is a stop signal, the operating mode of the range hood is determined to be a stop mode.

[0074] Optionally, as can be seen from the above embodiment, the linkage signal is a signal output by the cooker 20. The linkage signal may include, but is not limited to, an operating signal and a shutdown signal. In this embodiment, when the range hood 10 determines that the received linkage signal is an operating signal, it determines that the operating mode of the range hood 10 is the operating mode and controls the fan assembly 11 and the light-emitting assembly 12 to operate in the operating mode. When the range hood 10 determines that the received linkage signal is a shutdown signal, it determines that the operating mode of the range hood 10 is the shutdown mode and controls the fan assembly 11 and the light-emitting assembly 12 to operate in the shutdown mode.

[0075] Reference Figure 3 、 Figure 8 and Figure 9 In one embodiment of the present invention, the range hood 10 further includes a detection component 14, and the detection component 14 is used to detect the smoke concentration; the method further includes the following steps:

[0076] S40: Adjust the brightness of the light-emitting component according to the smoke concentration detected by the detection component.

[0077] Optionally, in this embodiment, the range hood 10 further includes a detection component 14. The detection component 14 is implemented using a smoke sensor, such as an ionization smoke sensor or a photoelectric smoke sensor. The source of the ionization smoke sensor or the photoelectric smoke sensor is not particularly limited herein. The smoke sensor is used to detect the smoke concentration generated by the cooker 20 when the cooker 20 is operating. The range hood 10 automatically adjusts the brightness of the light-emitting component 12 based on the smoke concentration detected by the smoke sensor. For example, when the smoke concentration detected by the smoke sensor is high, the range hood 10 increases the brightness of the light-emitting component 12; when the smoke concentration detected by the smoke sensor is low, the range hood 10 decreases the brightness of the light-emitting component 12. With this configuration, regardless of the smoke concentration generated by the cooker 20, the user can perceive the operating status of the range hood 10 through the brightness changes of the light-emitting component 12.

[0078] Reference Figure 4 、 Figure 8 and Figure 9 In one embodiment of the present invention, the second light emitting mode includes a third light emitting mode and a fourth light emitting mode, and the brightness of the light emitting component 12 is adjusted according to the smoke concentration detected by the detection component 14, including:

[0079] S41, when the detected smoke concentration is within a preset smoke concentration range, controlling the light-emitting component to operate in a second light-emitting mode;

[0080] S42. When the detected smoke concentration increases to a maximum value within a preset smoke concentration range, controlling the light-emitting component to operate in a third light-emitting mode, and controlling the fan component to operate at a first speed;

[0081] S43. When the detected smoke concentration decreases to a minimum value of a preset smoke concentration range, control the light-emitting component to operate in a fourth light-emitting mode, and control the fan component to operate at a second speed, which is lower than the first speed.

[0082] Optionally, the first lighting mode controls the lighting component 12 to gradually switch between a first brightness and a second brightness, where the first brightness is less than the second brightness; the second lighting mode controls the lighting component 12 to gradually switch between a second brightness and a third brightness, where the second brightness is greater than the first brightness and less than the third brightness; the third lighting mode controls the lighting component 12 to gradually switch between a fourth brightness and a third brightness, where the fourth brightness is greater than the second brightness and less than the third brightness; and the fourth lighting mode controls the lighting component 12 to gradually switch between the second brightness and the fourth brightness. In this embodiment, the first brightness is 0%, the second brightness is 80%, the third brightness is 100%, and the fourth brightness is 90%.

[0083] When the range hood 10 determines that the smoke concentration detected by the smoke sensor is within the preset smoke concentration range, which indirectly reflects that the smoke concentration in the cooking environment where the user is currently located is within a moderate range, the range hood 10 controls the fan assembly 11 to operate within the preset speed range, that is, to operate at any speed between the second speed and the first speed, to appropriately discharge smoke from the user's cooking environment, thereby improving the safety of the user's cooking. The range hood 10 also controls the light-emitting assembly 12 to operate in the second light-emitting mode, that is, to maintain the brightness of the light-emitting assembly 12 within the range of 80% to 100%. This ensures that the light-emitting assembly 12 can provide sufficient brightness for the user to perceive the working status of the range hood 10 in a moderate smoke environment.

[0084] When the range hood 10 determines that the smoke concentration detected by the smoke sensor increases to the maximum value of the preset smoke concentration range, which indirectly reflects that there is too much smoke in the cooking environment where the user is at this time, the range hood 10 controls the fan assembly 11 to operate at the first speed to accelerate the exhaust of smoke in the cooking environment where the user is, thereby improving the safety of the user's cooking, and controls the light-emitting assembly 12 to operate in a third light-emitting mode of the second light-emitting mode, that is, the brightness of the light-emitting assembly 12 is maintained in the range of 90% to 100%. In this way, it can ensure that the light-emitting assembly 12 can provide sufficient brightness for the user to perceive the working status of the range hood 10 in a smoky environment;

[0085] When the range hood 10 determines that the smoke concentration detected by the smoke sensor is reduced to the minimum value of the preset smoke concentration range, it indirectly reflects that there is less smoke in the cooking environment where the user is at this time. The range hood 10 controls the fan component 11 to operate at the second speed, slowly discharges the smoke in the cooking environment where the user is, and improves the user's cooking comfort, and controls the light-emitting component 12 to work in the fourth light-emitting mode of the second light-emitting mode, that is, the brightness of the light-emitting component 12 is maintained in the range of 80% to 90%. Compared with the light-emitting component 12 working in the third light-emitting mode, the light-emitting component 12 can be more energy-efficient at this time, while also ensuring that it can provide sufficient brightness for the user to perceive the working status of the range hood 10 in a low-smok environment.

[0086] Reference Figure 5 、 Figure 8 and Figure 9 In one embodiment of the present invention, the method further comprises the following steps:

[0087] S50: When a timed shutdown signal is received, the light-emitting component is controlled to turn off after working in the fifth light-emitting mode for a first preset time period.

[0088] Optionally, the fifth lighting mode controls the lighting assembly 12 to gradually switch between a fifth brightness and a third brightness, with the fifth brightness being lower than the third brightness. In this embodiment, the fifth brightness is 50% and the third brightness is 100%. The first preset duration is the preset time for the cooker 20 or range hood 10 to operate on a scheduled basis, i.e., the time for the lighting assembly 12 to operate on a scheduled basis. The specific duration can be manually set and stored in the control assembly 21 of the cooker 20.

[0089] As can be seen from the above embodiment, the operating modes of the range hood 10 may include, but are not limited to, an operating mode and an off mode, and may also include a timed off mode. In this embodiment, when the range hood 10 receives a timed off signal from the cooktop 20, it determines that its operating mode is the timed off mode and accordingly controls the light-emitting assembly 12 to extinguish after operating in the fifth lighting mode for a first preset duration. In other words, when the range hood 10 begins its scheduled off mode, the brightness of the light-emitting assembly 12 slowly rises and falls within a range of 50% to 100% until the timed off time expires, at which point the light-emitting assembly 12 extinguishes, thereby completing the shutdown of the cooktop 20 and the range hood 10.

[0090] Reference Figure 6 、 Figure 8 and Figure 9 In one embodiment of the present invention, the method further comprises the following steps:

[0091] S60: When the purification signal is received, the light of the light-emitting component is controlled to be adjusted from the first color to the second color, and the light-emitting component is controlled to operate in the fifth light-emitting mode.

[0092] Optionally, as can be seen from the above embodiments, the operating modes of the range hood 10 may include, but are not limited to, an operating mode, an off mode, and a timed off mode, and may also include a fresh air mode. The fresh air mode improves indoor air quality by introducing fresh air from outside. This mode not only regulates the indoor temperature but also provides fresh air, helping to reduce indoor air pollution and the spread of allergens, thereby improving the comfort and health of the indoor environment. In this embodiment, when the range hood 10 receives a purification signal output by the stove 20, it determines that its operating mode is fresh air mode and accordingly controls the lighting of the light-emitting assembly 12 to adjust from a first color to a second color, where the first color is warm yellow and the second color is green. The light-emitting assembly 12 is also controlled to operate in a fifth lighting mode, where the brightness of the light-emitting assembly 12 slowly increases within a range of 50% to 100%. When the fresh air mode ends, the light of the light-emitting assembly 12 is extinguished.

[0093] Reference Figures 7 to 9 In one embodiment of the present invention, the method further comprises the following steps:

[0094] S70: When a dry-heat signal is received, the light of the light-emitting component is controlled to be adjusted from the first color to the third color, and the light-emitting component is controlled to flash quickly for a second preset duration.

[0095] Optionally, it can be seen from the above embodiments that the working modes of the range hood 10 include not only the operating mode, the shutdown mode, the timed shutdown mode and the fresh air mode, but also a dry-burning mode. This is because the smoke sensor of the present application detects the smoke generated by the stove 20 in real time. If the smoke concentration is detected to be in a high concentration state for a long time, the smoke sensor can determine that the stove 20 is in a dry-burning state and output a corresponding dry-burning signal to the range hood 10. According to the received dry-burning signal, the range hood 10 controls the light of the light-emitting component 12 to adjust from the first color to the third color, wherein the first color is warm yellow and the second color is red, and controls the light-emitting component 12 to flash quickly for the second preset time length, so that the user can turn off the stove 20 to improve safety. It is worth noting that the second preset time length is the dry-burning reminder length, preferably 5 seconds. After the smoke is eliminated, the light of the light-emitting component 12 is turned off accordingly.

[0096] Reference Figure 10 The present invention also proposes a control device 13, which includes a memory and a processor. The processor stores a range hood 10 control program on the memory and is executed by the processor. When the range hood 10 control program is executed by the processor, the range hood control method as described above is implemented. The specific structure of the range hood control method refers to the above embodiment. Since the control device 13 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0097] Reference Figure 11 The present invention also proposes a range hood 10, which includes a fan assembly 11, a light-emitting assembly 12 and a control device 13. The specific structure of the control device 13 refers to the above embodiment. Since the range hood 10 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0098] In this embodiment, the fan assembly 11 can be implemented by a baffle-type centrifugal fan, a mixed-flow centrifugal fan, a centrifugal fan or an axial-flow fan, and is mainly used to discharge the smoke generated by the range hood 10 when in working state to avoid bacterial growth indoors and affecting human health.

[0099] The light-emitting assembly 12 can be implemented as a narrow strip light, a square light, a round light, or a light of other shapes, and its size is not particularly limited. The installation position of the light-emitting assembly 12 on the range hood 10 can be at the top of the range hood 10, illuminating the ground, or illuminating in a direction away from the wall, or illuminating in the front and lower part of the range hood 10, and there is no specific limitation here. The light-emitting assembly 12 is used to automatically turn on when the range hood 10 is turned on, and emit light indicating the working status of the range hood 10, and to automatically turn off when the range hood 10 is turned off. That is, when the stove 20 and the range hood 10 are used in conjunction, the stove 20 conveys status information such as operation and shutdown to the range hood 10, and the light color and dynamics of the light-emitting assembly 12 are displayed. The user does not need to check the icons and text lights on the control panel to more intuitively feedback the working status of the range hood 10.

[0100] The control device 13 can be implemented by a controller or a control chip, and the model of the controller or the control chip is not particularly limited here. In actual application, the control device 13 receives the linkage signal output by the stove 20 in real time, and when receiving the linkage signal, determines the working mode of the range hood 10 according to the linkage signal, wherein the working mode of the range hood 10 may include but is not limited to the operation mode and the shutdown mode. The operation mode and the shutdown mode are set according to the working state of the range hood 10. Specifically, the operation mode is the mode in which the range hood 10 is in the operation state, and the shutdown mode is the mode in which the range hood 10 is in the shutdown state. Optionally, this embodiment mainly divides the working mode of the range hood 10 into the operation mode and the shutdown mode. Of course, in other embodiments, more modes can be set according to the working state of the range hood 10, and no further details will be given here.

[0101] Furthermore, when the control device 13 determines that the working mode of the range hood 10 is the operating mode, the control device 13 controls the fan assembly 11 to operate so as to discharge the smoke of the product produced by the user during the cooking process, and controls the light-emitting assembly 12 to adjust from the first light-emitting mode to the second light-emitting mode. It should be noted that the first light-emitting mode is that the control device 13 controls the light-emitting assembly 12 to gradually switch between the first brightness and the second brightness; the second light-emitting mode is that the control device 13 controls the light-emitting assembly 12 to gradually switch between the second brightness and the third brightness. In this embodiment, the first brightness is 0%, the second brightness is 80%, and the third brightness is the maximum brightness of the light-emitting assembly 12, specifically 100%. When the range hood 10 is started, the control device 13 controls the light of the light-emitting assembly 12 to slowly brighten from the first light-emitting mode to the second light-emitting mode until it is fully lit. During this period, the light is dynamically displayed, which allows the user to intuitively understand the operating status of the range hood 10.

[0102] Similarly, when the control device 13 determines that the operating mode is the shutdown mode, the control device 13 controls the fan assembly 11 to stop operating and controls the light-emitting assembly 12 to adjust from the second lighting mode to the first lighting mode. In this embodiment, when the range hood 10 is turned off, the control device 13 controls the light of the light-emitting assembly 12 to gradually dim from the second lighting mode to the first lighting mode until the light is completely extinguished. During this period, the light is also dynamically displayed, which also facilitates the user to intuitively understand the shutdown status of the range hood 10.

[0103] Reference Figure 11 In one embodiment of the present invention, the range hood 10 further includes:

[0104] The detection component 14 is electrically connected to the control device 13 ; the detection component 14 is used to detect the smoke concentration generated by the range hood 10 .

[0105] Optionally, detection component 14 is implemented using a smoke sensor, such as an ionization smoke sensor or a photoelectric smoke sensor. The source of the ionization smoke sensor or the photoelectric smoke sensor is not particularly limited. The smoke sensor is used to detect the smoke concentration generated by the cooker 20 when the cooker 20 is in operation. The range hood 10 automatically adjusts the brightness of the light-emitting component 12 based on the smoke concentration detected by the smoke sensor. For example, when the smoke sensor detects a high smoke concentration, the range hood 10 increases the brightness of the light-emitting component 12; when the smoke sensor detects a low smoke concentration, the range hood 10 decreases the brightness of the light-emitting component 12. This configuration ensures that, regardless of the smoke concentration generated by the cooker 20, the user can detect the operating status of the range hood 10 through the brightness changes of the light-emitting component 12.

[0106] Reference Figure 11The present invention also proposes a smoke-stove linkage system, which includes a stove 20 and / or a range hood 10. The range hood 10 is connected to the stove 20 via a communication component 15. The specific structure of the range hood 10 refers to the above embodiment. Since the smoke-stove linkage system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0107] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
