Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to an oil fume treatment device and a control method. Background Art

[0002] The range hood includes an operation panel assembly 100, which is used to display icons 20. The operator 7000 can operate the icons 20 to implement different functions of the range hood. Figure 5 and Figure 6 As shown, the operation panel assembly 100 also includes a detection device communicatively connected to the control mechanism 50, the detection device includes a detection module 30', each detection module 30' corresponds one-to-one with an icon 20 and is connected to the control mechanism 50, and the operator 7000 operates the detection module 30' to achieve non-contact triggering operation on the icon 20.

[0003] like Figure 5 and Figure 6 As shown, the detection module 30' is arranged above and in front of the icon 20, and the detection module 30' is located above the operating body 6000. The operating body 6000 has a palm 6100 and a finger 6200. Each detection module 30' includes a first transmitter 31' and a first receiver 32' arranged along the left-right direction. When the operating body 6000 triggers the detection device in a predetermined posture, when there is an operating body 6000 below the corresponding detection module 30', the light emitted by the first transmitter 31' is reflected by the operating body 6000 below, and the light reflected by the operating body 6000 is received by the first receiver 32'. The control mechanism 50 determines that the corresponding detection module 30' is triggered and controls the corresponding action of the functional mechanism corresponding to the relevant detection module 30'.

[0004] like Figure 5 and Figure 6 As shown, when the operating body 6000 triggers the detection device in a triggering posture, the operating body 6000 is in a state where only the index finger is extended and the other fingers are rolled up, and the palm 6100 is arranged parallel to the operating panel 10. Although the operator 7000 originally wanted to trigger the second detection module 30' on the right (i.e., the detection module 30' corresponding to the first detection area M1) with the index finger, the operating body 6000 spans the first detection area M1 and the second detection area M2. In other words, the second and third detection modules 30' from the right are both triggered, resulting in an accidental touch of the operating panel assembly 100, affecting the operator 7000's correct triggering of the range hood related functions.

[0005] Therefore, it is urgent to design a new oil fume treatment device and control method to solve the problem of accidental touch of the operation panel components, which affects the operator's ability to correctly trigger the relevant functions of the range hood. Summary of the invention

[0088] Embodiment 1

[0089] like Figure 1 to Figure 4 As shown, the embodiment of the present disclosure provides an oil fume treatment device, which can be a range hood, an integrated stove, etc. The embodiment of the present disclosure is explained by taking a range hood as an example, the range hood includes a shell 200, a fan 700 and a movable part 300, wherein the fan 700 is arranged inside the shell 200, and the movable part 300 includes a smoke collecting chamber body 310 and a smoke collecting plate 320, the smoke collecting chamber body 310 can extend or retract relative to the shell 200, a smoke inlet 3101 is provided on the smoke collecting chamber body 310, and the smoke collecting plate 320 is arranged on the smoke collecting chamber body 310, and the smoke collecting plate 320 can switch between a first state of opening the smoke inlet 3101 and a second state of blocking the smoke inlet 3101. Figure 2As shown, when the smoke collecting chamber body 310 extends out of the shell 200 and the smoke collecting plate 320 is in the first state, the oil smoke passes through the smoke inlet 3101, the interior of the smoke collecting chamber body 310 and the shell 200 in sequence and is discharged. When the smoke collecting chamber body 310 is retracted in the shell 200 and the smoke collecting plate 320 is in the second state, a better retraction effect of the movable part 300 can be achieved. It should be noted that the aforementioned range hood is only one type of retractable range hood, and the range hood of the embodiment of the present disclosure can also be various types of range hoods such as top suction type, side suction type, ultra-thin type, etc., and all types of range hoods are within the protection scope of the embodiment of the present disclosure.

[0090] In an optional embodiment, if Figure 2 As shown, the range hood further includes a detection mechanism 40, which is electrically connected to a control mechanism 50 (not shown) of the range hood, and the control mechanism 50 is also respectively connected to the movable part 300 and the fan 700 for communication. A stove 3000 is arranged below the range hood, and a stove 2000 is arranged on the stove 3000. The detection mechanism 40 is arranged on the mounting assembly 600 and is used to detect the temperature of the pot 4000 on the stove 2000. The control mechanism 50 can control the working state of the movable part 300 and the fan 700 according to the temperature of the pot 4000 on the stove 2000, so as to achieve the adaptive adjustment of the temperature of the pot 4000 and the range hood in different working states, and achieve a better absorption effect of the range hood on oil smoke.

[0091] Exemplarily, this optional embodiment does not limit the type of detection mechanism 40, for example, it can be set as an active infrared temperature sensor or a passive infrared temperature sensor. The active infrared temperature sensor emits infrared rays, which are reflected after contacting the object to be measured and are received by the active infrared temperature sensor again to measure the temperature of the object to be measured; the temperature measurement principle of the passive infrared temperature sensor is as follows: when the temperature of the object is higher than the thermodynamic zero, infrared rays will radiate to the surroundings, and the passive infrared temperature sensor detects the infrared radiation energy of the object to detect the temperature of the object to be measured. In addition to the above two types, any infrared temperature sensor that can achieve non-contact measurement of the temperature of the object to be measured is within the protection scope of the technical solution of the present invention.

[0092] In an optional embodiment, if Figure 2 As shown, each stove 2000 is provided with a detection mechanism 40 corresponding to each other, and each detection mechanism 40 can accurately detect the temperature of the pot 4000 on the corresponding stove 2000. Exemplarily, the number P of the detection mechanisms 40 can be one, two, three or more, and the number P of the detection mechanisms 40 corresponds to the number P of the stoves 2000.

[0093] In an optional embodiment, if Figure 2As shown, two detection mechanisms 40 are provided, and two stoves 2000 of this optional embodiment are provided. Each detection mechanism 40 corresponds to one stove 2000 one by one, so that the detection mechanism 40 can accurately detect the temperature of the pot 4000 on the corresponding stove 2000.

[0094] In an optional embodiment, if Figure 2 As shown, two detection mechanisms 40 are arranged on both sides of the smoke collecting plate 320 along the left-right direction. In addition, the detection signal M emitted by each detection mechanism 40 is located on the outside of the smoke collecting plate 320, thereby avoiding interference of the smoke collecting plate 320 with the detection signal M, thereby ensuring that each detection mechanism 40 always accurately detects the temperature of the cookware 4000.

[0095] like Figure 1 to Figure 4 As shown, the range hood further includes an operation panel assembly 100, which is disposed on the housing 200. The operation panel assembly 100 is used to display icons 20. The operator 7000 can operate the icons 20 to realize different functions of the range hood. Figure 3 and Figure 4 As shown, the operation panel assembly 100 includes an operation panel 10, a light-emitting element 60 and an icon 20, wherein the operation panel 10 is directly or indirectly connected to the housing 200, the icon 20 is embedded in the operation panel 10, the light-emitting element 60 is arranged on one side of the operation panel 10, and the light-emitting element 60 is arranged opposite to the corresponding icon 20. The light-emitting element 60 can realize the function of lighting up the icon 20, so that the icon 20 emits light, which is convenient for the operator 7000 to identify the icon 20, and is convenient for the operator 7000 to accurately trigger the icon 20, avoiding the operator 7000 from accidentally touching the icon 20. Exemplarily, the operation panel 10 can be transparent plastic, transparent glass, polymethyl methacrylate, etc., and all transparent materials that can be made into panels are within the protection scope of the embodiments of the present disclosure. Exemplarily, the light-emitting element 60 can be RGB lamps, LED lamps, etc., and all structures that can realize light emission are within the protection scope of the embodiments of the present disclosure. For example, the icon 20 can be formed by a laser screen printing process, an etching process, a laser engraving process, etc. on the inside of the operation panel 10, so as to realize rapid processing and formation of the icon 20. In an optional embodiment, the icon 20 is located inside the operation panel 10, which can also prevent the icon 20 from being polluted by external oil smoke or oil, so as to realize a good luminous and shining effect of the icon 20 at all times.

[0096] like Figure 5 to Figure 7As shown, the operation panel assembly 100 also includes a detection device communicatively connected to the control mechanism 50, the detection device includes a detection module 30', each detection module 30' corresponds one-to-one with an icon 20 and is connected to the control mechanism 50, and the operator 7000 operates the detection module 30' to achieve non-contact triggering operation on the icon 20.

[0097] like Figure 5 and Figure 6 As shown, the detection module 30' is arranged above and in front of the icon 20, and the detection module 30' is located above the operating body 6000. The operating body 6000 has a palm 6100 and a finger 6200. Each detection module 30' includes a first transmitter 31' and a first receiver 32' arranged along the left-right direction. When the operating body 6000 triggers the detection device in a predetermined posture, when there is an operating body 6000 below the corresponding detection module 30', the light emitted by the first transmitter 31' is reflected by the operating body 6000 below, and the light reflected by the operating body 6000 is received by the first receiver 32'. The control mechanism 50 determines that the corresponding detection module 30' is triggered and controls the corresponding action of the functional mechanism corresponding to the relevant detection module 30'. It should be noted that the operating body 6000 of the embodiment of the present disclosure is not limited to the user's hand, but can also be an insect, an operating stick, an indicator shaped like a hand, etc. All structures and objects that can trigger the icon 20 and the detection module 30' are within the protection scope of this optional embodiment and will not be further described in detail in the embodiment of the present disclosure.

[0098] like Figure 7 As shown, the detection module 30' is arranged above and in front of the icon 20, and the detection module 30' is located on the rear side of the operating body 6000. The operating body 6000 has a palm 6100 and a finger 6200. Each detection module 30' includes a second transmitter 33' and a second receiver 34' arranged along the left and right directions. When the operating body 6000 triggers the detection device in a predetermined posture, when there is an operating body 6000 below the corresponding detection module 30', the light emitted by the second transmitter 33' is reflected by the operating body 6000 below, and the light reflected by the operating body 6000 is received by the second receiver 34'. The control mechanism 50 determines that the corresponding detection module 30' is triggered and controls the corresponding action of the functional mechanism corresponding to the relevant detection module 30'.

[0099] like Figure 5 and Figure 6As shown, when the operating body 6000 triggers the detection device in a triggering posture, the operating body 6000 is in a state where only the index finger is extended and the other fingers 6200 are retracted, and the palm 6100 is arranged parallel to the operating panel 10. Although the operator 7000 originally wanted to trigger the second detection module 30' on the right (i.e., the detection module 30' corresponding to the first detection area M1) with the index finger, the operating body 6000 spans the first detection area M1 and the second detection area M2. In other words, the second and third detection modules 30' from the right are both triggered, resulting in an accidental touch of the operating panel assembly 100, affecting the operator 7000's correct triggering of the range hood related functions.

[0100] like Figure 7 As shown, when the operating body 6000 triggers the detection device in a triggering posture, the operating body 6000 is in a state where only the index finger is extended and the other fingers 6200 are retracted, and the palm 6100 is arranged vertically to the operating panel 10. Although the operator 7000 originally intended to trigger the third detection module 30' on the right (i.e., the detection module 30' corresponding to the third detection area N1) with the index finger, the operating body 6000 spans the third detection area N1, the fourth detection area N2 and the fifth detection area N3. In other words, the third detection module 30', the fourth detection module 30' and the fifth detection module 30' from the right are all triggered, resulting in an accidental touch of the operating panel assembly 100, affecting the operator 7000's correct triggering of the range hood related functions.

[0101] To solve the above problems, Figure 8 to Figure 10 As shown, at least two icons 20 are arranged on the operation panel 10, each icon 20 is provided with a corresponding detection area 5000 in a one-to-one correspondence, each single icon 20 corresponds to the corresponding action of the corresponding functional mechanism, and the first detection device 30 is used to trigger the corresponding action of the functional mechanism corresponding to the icon 20 corresponding to the detection area 5000 when there is an operating body 6000 in only one detection area 5000, which can avoid accidental touching of the operation panel assembly 100 when there are operating bodies 6000 in multiple detection areas 5000, and ensure that the operator 7000 can correctly trigger the relevant functions of the range hood.

[0102] In an optional embodiment, if Figure 11 to Figure 22As shown, the first detection device 30 is also used to obtain the operating posture of the operating body 6000 and determine the functional mechanism and corresponding actions actually triggered according to the operating posture of the operating body 6000 when there are operating bodies 6000 in at least two detection areas 5000, so as to specifically analyze the operating posture that may cause mis-touch, and make a correct triggering of the relevant functions of the range hood in combination with the corresponding analysis, and to convert the operating posture that may cause mis-touch into the functional mechanism and corresponding actions actually triggered, so as to ensure the correct triggering of the relevant functions of the range hood by the operator 7000. Compared with the aforementioned solution, the range hood of this optional embodiment can ensure that most of the operating postures of the operating body 6000 can achieve the correct triggering of the relevant actions of the expected functional mechanism, effectively reduce the invalid operating postures of the operating body 6000, avoid the need for the operator 7000 to repeatedly adjust the operating posture of the operating body 6000, make the operation of the range hood by the operator 7000 more humane, intelligent and convenient, and facilitate the convenient use of the range hood by the operator 7000.

[0103] For example, Figure 11 to Figure 14 As shown, the first detection device 30 includes a second distance detection mechanism 34 and a third image detection mechanism 35, the second distance detection mechanism 34 and the third image detection mechanism 35 are both communicatively connected to the control mechanism 50, each second distance detection mechanism 34 corresponds to an icon 20, the second distance detection mechanism 34 and the operating body 6000 are arranged along the up-down direction, the second distance detection mechanism 34 can emit detection light along the up-down direction, and the third image detection mechanism 35 is used to obtain the operating posture of the operating body 6000; if the palm 6100 of the operating body 6000 is arranged parallel to the detection light, the second distance detection mechanism 34 is used to detect the fifth minimum distance L5 between it and the operating body 6000 in each detection area 5000 along the up-down direction, and the operating body 6000 is in this state, the control mechanism 50 can determine that the single icon 20 corresponding to the detection area 5000 with the smallest fifth minimum distance L5 and the corresponding action of the corresponding functional mechanism are actually triggered, which can realize accurate recognition of irregular operation of the operating body 6000 and ensure that the operator 7000 correctly triggers the relevant functions of the range hood.

[0104] Specifically, if Figure 11 to Figure 14 As shown, the second distance detection mechanism 34 may include a second emitting element 341 and a second receiving element 342. Both the second emitting element 341 and the second receiving element 342 are communicatively connected to the control mechanism 50. The light emitted by the second emitting element 341 is reflected after contacting the operating body 6000. The reflected light is received by the second receiving element 342. The control mechanism 50 can calculate the fifth minimum distance L5 based on the relevant signal.

[0105] In an optional embodiment, if Fig.11As shown, the operation panel assembly 100 also includes a protective cover 91, and the protective cover 91 includes a protective cover body 911 and a partition 912. At least two second distance detection mechanisms 34 are arranged in the protective cover body 911, and a partition 912 is arranged between two adjacent second distance detection mechanisms 34. Through the setting of the partition 912, signal interference between different second distance detection mechanisms 34 can be avoided, ensuring that each second distance detection mechanism 34 can obtain more accurate detection data.

[0106] In an optional embodiment, if Fig.11 As shown, a partition 912 is also provided between the second emitting element 341 and the second receiving element 342 of the same second distance detecting mechanism 34. By providing the partition 912, signal interference between the second emitting element 341 and the second receiving element 342 can be avoided, thereby ensuring that the second distance detecting mechanism 34 can obtain more accurate detection data.

[0107] Exemplarily, the third image detection mechanism 35 may include one or more cameras, video cameras, etc., and the third image detection mechanism 35 cooperates with the control mechanism 50 to obtain the operation posture of the operating body 6000, the coordinate position in space, etc.

[0108] In an optional embodiment, if Figure 15 to Figure 18 As shown, the first detection device 30 includes a first distance detection mechanism 32 and a second image detection mechanism 33, both of which are communicatively connected to the control mechanism 50, the operating body 6000 and the first distance detection mechanism 32 are arranged along the front-to-back direction, and the second image detection mechanism 33 is used to obtain the operating posture of the operating body 6000; if the palm 6100 of the operating body 6000 is arranged parallel to or perpendicular to the detection light, the first distance detection mechanism 32 can emit a detection light along the front-to-back direction, and the first distance detection mechanism 32 is used to detect the fourth minimum distance L4 between it and the operating body 6000 in each detection area 5000 along the front-to-back direction. When the operating body 6000 is in this state, the control mechanism 50 can determine that the single icon 20 corresponding to the detection area 5000 with the smallest fourth minimum distance L4 and the corresponding action of the corresponding functional mechanism are actually triggered, so as to realize accurate recognition of irregular operation of the operating body 6000 and ensure that the operator 7000 correctly triggers the relevant functions of the range hood.

[0109] Specifically, if Figure 15 to Figure 18As shown, the first distance detection mechanism 32 may include a first emitting element 321 and a first receiving element 322. Both the first emitting element 321 and the first receiving element 322 are communicatively connected to the control mechanism 50. The light emitted by the first emitting element 321 is reflected after contacting the operating body 6000. The reflected light is received by the first receiving element 322. The control mechanism 50 can calculate the fourth minimum distance L4 based on the relevant signal.

[0110] Exemplarily, the second image detection mechanism 33 may include one or more cameras, video cameras, etc., and the second image detection mechanism 33 cooperates with the control mechanism 50 to obtain the operation posture of the operating body 6000, the coordinate position in space, etc.

[0111] In an optional embodiment, if Fig.19 and Fig.21 As shown, the first detection device 30 includes a first image detection mechanism 31, which is communicatively connected to the control mechanism 50, and is used to obtain the operating posture of the operating body 6000: if the palm 6100 of the operating body 6000 is parallel to the operating panel 10, and the operating panel 10 has an upper edge 11, the first image detection mechanism 31 is used to obtain the third minimum distance L3 between the operating body 6000 and the upper edge 11 in the up and down directions in each detection area 5000. When the operating body 6000 is in this state, the control mechanism 50 can determine that the single icon 20 corresponding to the detection area 5000 where the third minimum distance L3 is the smallest and the corresponding action of the corresponding functional mechanism are actually triggered, which can realize accurate identification of irregular operation of the operating body 6000 and ensure that the operator 7000 correctly triggers the relevant functions of the range hood.

[0112] In an optional embodiment, if Fig. 20 and Fig.21 As shown, the first detection device 30 includes a first image detection mechanism 31, which is communicatively connected to the control mechanism 50, and is used to obtain the operating posture of the operating body 6000: if the palm 6100 of the operating body 6000 is parallel to the operating panel 10, the first image detection mechanism 31 is also used to obtain the second minimum distance L2 between the operating body 6000 and the operating panel 10 in the front-to-back direction in each detection area 5000. When the operating body 6000 is in this state, the control mechanism 50 can determine that the single icon 20 corresponding to the detection area 5000 with the largest second minimum distance L2 and the corresponding action of the corresponding functional mechanism are actually triggered, which can realize accurate identification of irregular operation of the operating body 6000 and ensure that the operator 7000 correctly triggers the relevant functions of the range hood.

[0113] In an optional embodiment, if Fig.21 and Fig. 22 As shown, the first detection device 30 includes a first image detection mechanism 31, which is communicatively connected to the control mechanism 50, and is used to obtain the operating posture of the operating body 6000: if the palm 6100 of the operating body 6000 is in a vertical state with the operating panel 10, the first image detection mechanism 31 is also used to obtain the first minimum distance L1 between the operating body 6000 and the operating panel 10 along the front-to-back direction in each detection area 5000. When the operating body 6000 is in this state, the control mechanism 50 can determine that the single icon 20 corresponding to the detection area 5000 with the smallest first minimum distance L1 and the corresponding action of the corresponding functional mechanism are actually triggered, which can realize accurate identification of irregular operation of the operating body 6000 and ensure that the operator 7000 correctly triggers the relevant functions of the range hood.

[0114] Exemplarily, the first image detection mechanism 31 may include one or more cameras, video cameras, etc., and the first image detection mechanism 31 cooperates with the control mechanism 50 to obtain the operation posture of the operating body 6000, the coordinate position in space, etc. This optional embodiment only sets the first image detection mechanism 31 without additionally setting a distance detection mechanism, so that the first detection device 30 has a simple structure, is easy to assemble, has a simple control method, and is low in cost.

[0115] Insects such as flies, mosquitoes and cockroaches are inevitable in the kitchen space. If the insects crawl into the corresponding detection area 5000, the insects may cause the range hood to be accidentally touched.

[0116] To solve the above problem, in an optional embodiment, as Figure 3 and Figure 4 As shown, the operation panel assembly 100 also includes a second detection device 80, which is communicatively connected to the control mechanism 50. The second detection device 80 is used to detect whether there is an operator 7000 on the front side of the operation panel 10. If it is detected that there is no operator 7000 on the front side of the operation panel 10, the control mechanism 50 will not operate the functional mechanism corresponding to the detection area 5000 where the operating body 6000 exists, which can greatly reduce the risk of accidental touching of the range hood.

[0117] In an optional embodiment, if Figure 4 As shown, the operation panel assembly 100 also includes a cover body 92, which is arranged in the shell 200 and covers the outer periphery of the second detection device 80. The cover body 92 can prevent oil stains inside the range hood from dripping onto the second detection device 80, thereby ensuring better cleanliness of the second detection device 80 and more accurate detection effect.

[0118] For example, Figure 4 and Fig.23As shown, the second detection device 80 can be a radar detection mechanism. By setting the cover 92 and the decorative member 63 to be made of metal, the cover 92 and the decorative member 63 can shield a part of the radar detection mechanism, so that the radar detection mechanism can only detect Figure 3 The sector-shaped area shown is used to detect whether an operator 7000 is present, thereby avoiding misjudgment by the radar detection mechanism caused by the operation of the internal fan 700 in the range hood.

[0119] In other optional embodiments, the second detection device 80 may also be an infrared detection mechanism, etc. All mechanisms that can detect the operator 7000 are within the protection scope of this optional embodiment.

[0120] In an optional embodiment, if Figure 3 and Figure 4 As shown, the operation panel assembly 100 also includes an insect repelling device 70, which is used to control the insect repelling device 70 to repel the operating body 6000 when the first detection device 30 detects the presence of the operating body 6000 in the detection area 5000 and the second detection device 80 does not detect the operator 7000, so as to avoid the contamination of the range hood and the kitchen environment by insects and improve the cleanliness of the range hood and the kitchen environment.

[0121] In an optional embodiment, if Figure 4 As shown, the insect repelling device 70 may include a vibration mechanism 71, which is in communication with the control mechanism 50. When the first detection device 30 detects that the operating body 6000 exists in the detection area 5000 and the second detection device 80 does not detect the operator 7000, the control mechanism 50 controls the vibration mechanism 71 to vibrate, and the vibration generated by the vibration mechanism 71 can effectively repel insects. For example, Figure 4 As shown, the vibration mechanism 71 can be a vibration motor, a pneumatic vibrator, etc. All mechanisms that can emit vibrations are within the protection scope of the embodiments of the present disclosure.

[0122] In an optional embodiment, if Figure 4 As shown, the insect repelling device 70 fits the operating panel 10 , and can effectively transmit vibration to the operating panel 10 , making it easier for the insect repelling device 70 to repel insects on the operating panel 10 .

[0123] In an optional embodiment, if Figure 4 As shown, the insect repellent device 70 is arranged on the back side of the operating panel 10, which can achieve the concealment of the insect repellent device 70, ensure the appearance of the operating panel assembly 100 is more beautiful, and can also avoid the pollution of oil smoke to the insect repellent device 70, thereby ensuring a longer life and better use effect of the insect repellent device 70.

[0124] In an optional embodiment, if Figure 4 As shown, the insect repelling device 70 may include a light emitting mechanism 72, which is in communication with the control mechanism 50. When the first detection device 30 detects that the operating body 6000 exists in the detection area 5000 and the second detection device 80 does not detect the operator 7000, the control mechanism 50 controls the light emitting mechanism 72 to emit light. The light emitting mechanism 72 can effectively repel insects. For example, Figure 4 As shown, the light-emitting mechanism 72 can be an RGB lamp, an LED lamp, etc., and all structures that can realize light emission are within the protection scope of this optional embodiment. Among them, the light-emitting mechanism 72 can select light of different colors according to the specific scene. Exemplarily, the color of the light-emitting mechanism 72 can be preferably white, and mosquitoes will avoid white objects among many colors. If the light-emitting mechanism 72 emits white light for more than a preset time (such as 1 minute to 5 minutes) and the insect has not been driven away, the control mechanism 50 controls the light-emitting mechanism 72 to emit purple light. Mosquitoes like colors with longer wavelengths, and purple light can achieve more effective repelling of insects.

[0125] In an optional embodiment, if Figure 4 As shown, the insect repelling device 70 may include a blower mechanism 73, which is in communication with the control mechanism 50. When the first detection device 30 detects that the operating body 6000 exists in the detection area 5000 and the second detection device 80 does not detect the operator 7000, the control mechanism 50 controls the blower mechanism 73 to blow out airflow, and the airflow blown out by the blower mechanism 73 can effectively repel insects. For example, Figure 4 As shown, the light emitting mechanism 72 may be a fan, a blower, etc., and all structures capable of blowing out air flow are within the protection scope of this optional embodiment. Among them, the intensity of the blown air flow can be adaptively adjusted according to the length of time the insects stay. Specifically, the intensity of the air blown out by the blowing mechanism 73 increases as the length of time the insects stay increases.

[0126] In an optional embodiment, if Figure 4 As shown, the air outlet 731 of the blowing mechanism 73 is located upstream of the front side surface 12 of the operating panel 10 or directly opposite to the front side surface 12 of the operating panel 10. The airflow blown by the blowing mechanism 73 can blow away the dust on the front side surface 12. The airflow blown by the blowing mechanism 73 can also act as a wind curtain to prevent oil smoke from contaminating the operating panel 10.

[0127] In an optional embodiment, if Fig.23As shown, the range hood further includes a mounting assembly 600, which includes a mounting module and a first connecting member 68. The mounting module includes a first mounting member 61 and a second mounting member 62. The first mounting member 61 and the second mounting member 62 are located at the front and rear sides of the operation panel assembly 100. The mounting module is fixedly connected to the first connecting member 68, and the first mounting member 61 and the second mounting member 62 jointly clamp the operation panel 10 along the front and rear direction. Through the cooperation of the first mounting member 61, the second mounting member 62 and the first connecting member 68, with less structure, the mounting assembly 600 can achieve a stable clamping effect on the operation panel 10, and achieve a stable connection between the mounting assembly 600 and the operation panel 10.

[0128] In an optional embodiment, if Fig.23 As shown, the first mounting member 61 includes a first mounting portion 611 and a first pasting portion 612, one side of the first pasting portion 612 is pasted with the first mounting portion 611, and the other side of the first pasting portion 612 is pasted with one side of the operation panel 10; the second mounting member 62 includes a second mounting portion 621 and a second pasting portion 622, one side of the second pasting portion 622 is pasted with the second mounting portion 621, and the other side of the second pasting portion 622 is pasted with the other side of the operation panel 10. By setting the first pasting portion 612 and the second pasting portion 622, the first mounting member 61 and the second mounting member 62 can be further improved. The stable connection effect of the operating panel 10 is further enhanced, and the stable connection effect of the mounting assembly 600 and the operating panel 10 is further enhanced. Exemplarily, the first pasting portion 612 and the second pasting portion 622 can be double-sided adhesive, so that the first mounting member 61 and the second mounting member 62 can be respectively connected to the operating panel 10.

[0129] In an optional embodiment, if Fig.23 As shown, the housing 200 has a lower opening, and the mounting assembly 600 further includes a blocking member 64, which can block the lower opening on the housing 200, thereby preventing the internal structure of the range hood from being exposed from the lower opening, preventing oil droplets inside the range hood from leaking from the lower opening, and achieving a better sealing effect on the internal structure of the range hood. Fig.23As shown, the installation assembly 600 also includes a decorative piece 63, a blocking piece 64 is arranged between the installation module and the decorative piece 63, the installation module is connected to the decorative piece 63, and the installation module and the decorative piece 63 jointly clamp the blocking piece 64 in the up and down direction, so as to achieve a stable connection between the blocking piece 64 and the installation module and the decorative piece 63 respectively. Exemplarily, the installation module and the decorative piece 63 are fixedly connected by a fixing piece (not shown in the figure), so as to achieve a tight fixed connection between the installation module, the decorative piece 63 and the blocking piece 64 in the up and down direction. Specifically, the fixing piece can be a screw, a pin, a buckle assembly, etc., and all structures that can achieve a fixed connection between the installation module and the decorative piece 63 are within the protection scope of this optional embodiment.

[0132] Acquire the number P of the detection areas 5000 where the operating body 6000 exists; and

[0133] If there is only one detection area 5000 where an operating body 6000 is present, the functional mechanism corresponding to the detection area 5000 where the operating body 6000 is present is controlled to perform corresponding actions, thereby avoiding accidental touching of the operating panel assembly 100 when there are operating bodies 6000 in multiple detection areas 5000, and ensuring that the operator 7000 can correctly trigger the relevant functions of the range hood.

[0134] Embodiment 3

[0135] like Fig.25 As shown, the embodiment of the present disclosure discloses a control method, which is applied to any oil fume treatment device mentioned in the embodiment, and the control method is a further refinement of the control method disclosed in the second embodiment.

[0136] Before the step of obtaining the number P of the detection areas 5000 where the operating body 6000 exists, the method further includes:

[0137] Determine whether there is an operating body 6000 in the detection area 5000: If so, determine whether there is an operator 7000 in front of the operation panel 10;

[0138] If so, the step of obtaining the number P of the detection areas 5000 where the operating body 6000 exists is performed; this indicates that the operating body 6000 indeed belongs to the operator 7000, and the subsequent operation on the icon 20 can be continued.

[0139] If not, the insect repellent device 70 is controlled to repel the operating body 6000. When the first detection device 30 detects the existence of the operating body 6000 in the detection area 5000 and the second detection device 80 does not detect the operator 7000, the control mechanism 50 controls the insect repellent device 70 to repel the operating body 6000 to avoid the pollution of the range hood and the kitchen environment by insects and improve the cleanliness of the range hood and the kitchen environment.

[0140] In an optional embodiment, if Fig.24 As shown, after the step of obtaining the number P of the detection areas 5000 where the operating body 6000 exists, the following step is further included:

[0141] If there are at least two detection areas 5000 of the operating body 6000, the operating posture of the operating body 6000 is acquired;

[0142] According to the operation posture of the operating body 6000, the functional mechanism actually triggered and the corresponding action are determined.

[0143] By determining the functional mechanism actually triggered and the corresponding action, the operating posture that may lead to an accidental touch can be specifically analyzed, and the correct triggering of the range hood related functions can be made in combination with the corresponding analysis, and the operating posture that may lead to an accidental touch can be converted into the functional mechanism actually triggered and the corresponding action, so as to ensure the correct triggering of the range hood related functions by the operator 7000. Compared with the solution of the second embodiment, this optional embodiment can ensure that most of the operating postures of the operating body 6000 can achieve the correct triggering of the related actions of the expected functional mechanism, effectively reduce the invalid operating postures of the operating body 6000, avoid the operator 7000 from repeatedly adjusting the operating posture of the operating body 6000, make the operator 7000's control of the range hood more humane, intelligent and convenient, and facilitate the operator 7000's convenient use of the range hood.

[0144] Embodiment 4

[0145] like Fig.26 As shown, the embodiment of the present disclosure discloses a control method, which is applied to any oil fume treatment device mentioned in the embodiment, and the control method is a further refinement of the control method disclosed in the third embodiment.

[0146] Before obtaining the operation posture of the operating body 6000 and determining the actually triggered functional mechanism and the corresponding action according to the operation posture of the operating body 6000, the method further includes:

[0147] Obtain the detection time length T of the at least two detection areas 5000 having the operating body 6000 at the same time 检测 ;

[0148] Set the detection time T检测 With the preset time T 预设 For comparison:

[0149] If T 检测 Greater than or equal to T 预设 , determine the trigger mode as a combination key trigger mode, and trigger the corresponding action of the functional mechanism corresponding to the combination key;

[0150] If T 检测 Less than T 预设 , determine that the trigger mode is a single-key trigger mode, determine the single icon 20 actually triggered and the corresponding action of the corresponding functional mechanism, and perform the step of obtaining the operating posture of the operating body 6000.

[0151] The disclosed embodiment combines the combination key triggering mode and the single key triggering mode, so that more functions can be triggered by fewer icons 20. The structure of the operation panel assembly 100 is simple and the overall appearance is more concise.

[0152] It should be noted that the single-key trigger action for a single icon 20 corresponds one-to-one to the corresponding function of the corresponding functional mechanism, and the combination key trigger action corresponds one-to-one to the corresponding function of the corresponding function, and the relevant one-to-one correspondence is pre-stored in the control mechanism 50.

[0153] Exemplary description, T 预设 It can be 20s. 检测 When the time is greater than or equal to 20s, the control mechanism 50 determines the synchronously triggered icon 20 in the detection area 5000 where the operating body 6000 exists, and can determine the relevant actions of the functional mechanism corresponding to the synchronously triggered icon 20, and the control mechanism 50 can drive the aforementioned functional mechanism to perform corresponding actions.

[0156] The step of determining the functional mechanism actually triggered and the corresponding action includes:

[0157] If the palm 6100 of the operating body 6000 is in a vertical state with respect to the operating panel 10, the first minimum distance L1 between the operating body 6000 and the operating panel 10 along the front-to-back direction is obtained, and it is determined that the single icon 20 corresponding to the detection area 5000 where the first minimum distance L1 is the smallest and the corresponding action of the corresponding functional mechanism are actually triggered, thereby achieving accurate identification of irregular operations of the operating body 6000 and ensuring that the operator 7000 correctly triggers the relevant functions of the range hood.

[0158] If the palm 6100 of the operating body 6000 is parallel to the operating panel 10, the second minimum distance L2 between the operating body 6000 and the operating panel 10 along the front-to-back direction is obtained, and the single icon 20 corresponding to the detection area 5000 where the second minimum distance L2 is the largest and the corresponding action of the corresponding functional mechanism are actually triggered, which can achieve accurate identification of irregular operations of the operating body 6000 and ensure that the operator 7000 correctly triggers the relevant functions of the range hood.

[0159] If the palm 6100 of the operating body 6000 is parallel to the operating panel 10, the operating panel 10 has an upper edge 11, or the third minimum distance L3 between the operating body 6000 and the upper edge 11 in the up and down directions is obtained, it is determined that the single icon 20 corresponding to the detection area 5000 where the third minimum distance L3 is the smallest and the corresponding action of the corresponding functional mechanism are actually triggered, which can achieve accurate identification of irregular operations of the operating body 6000 and ensure that the operator 7000 correctly triggers the relevant functions of the range hood.
