When the air purification device 2 and the cigarette machine main body 1 work cooperatively, most of oil smoke generated in the cooking process is discharged to the outside through the oil smoke suction air duct, a small part of oil smoke can escape to other spaces in a kitchen, and the small part of oil smoke can be further removed through the purification air duct of the air purification device 2, so that the pollution of the oil smoke to the air environment and the damage to the health of a human body are further reduced.
In addition, according to the technical scheme of the invention, on one hand, the rotation of the air guide blade 23 is automatically driven by the driving motor 234, manual adjustment of a user is not needed, the intelligent automatic adjustment of the air outlet direction of the air purification device 2 can be realized, the convenience of the user is improved, and the user experience is improved; on the other hand, the controller 3 adjusts the working state of the driving motor 234 to drive the air guiding blade 23 to rotate to a preset position, so that the direction of the air outlet 202 faces to a preset direction, and the requirement of the user on the air outlet direction is met.
Alternatively, the cigarette maker body 1 and the air cleaning device 2 may share one controller 3, the controller 3 being typically fixedly mounted to the cigarette maker body 1; it will be appreciated that the cigarette maker body 1 is generally larger in volume and has more and more convenient locations and spaces for mounting the controller 3 than the air cleaning device 2. The controller 3 is typically in communication with the air cleaning device 2 by wire; of course, the controller 3 may also be in communication with the air purification apparatus 2 in a wireless manner. However, the design is not limited thereto, and in other embodiments, an independent controller may be provided corresponding to the cigarette maker body 1, and another independent controller may be provided corresponding to the air purifying device 2, so that the controller for controlling the air purifying device 2 is installed on the air purifying device 2.
Optionally, the driving motor 234 is in driving connection with the air guiding blade 23 through a transmission mechanism. It is understood that the additional transmission mechanism can make the position of the driving motor 234 more flexible. Alternatively, the drive mechanism may be a gear drive assembly, a pulley assembly, or the like.
In an embodiment, taking a gear transmission assembly as an example, referring to fig. 5 to 7, the transmission mechanism includes a first gear 235 disposed on the rotating shaft of the wind guiding blade 23 and a second gear 236 disposed on the output shaft of the driving motor 234, and the first gear 235 is engaged with the second gear 236; in this way, the rotation of the output shaft of the driving motor 234 is transmitted to the rotating shaft of the air guide vane 23 sequentially through the second gear 236 and the first gear 235, and the driving of the driving motor 234 to rotate the air guide vane 23 is realized.
Alternatively, the first gear 235 and the second gear 236 are both external gears, and the second gear 236 is disposed beside the first gear 235; in this way, the output shaft of the drive motor 234 can be provided coaxially with the rotation shaft of the air guide blade 23. However, the design is not limited thereto, and in other embodiments, the gear transmission assembly may be further configured as: one of the first gear and the second gear is an internal gear, the other one is an external gear, and the internal gear is sleeved outside the external gear; the mode of adopting internal gear cover external gear can reduce the required space that occupies of first gear and second gear on radial plane to reduce the product volume.
For the technical solution that the first gear 235 and the second gear 236 are both external gears, optionally, the radius of the first gear 235 is larger than the radius of the second gear 236, so that when the air guiding blade 23 rotates by a certain angle, the required rotation angle of the output shaft of the driving motor 234 is larger, which is beneficial to improving the control precision of the rotation angle of the air guiding blade 23.
Alternatively, referring to fig. 8 to 10, the plurality of air guiding blades 23 are provided at intervals, the plurality of air guiding blades 23 include a driving blade 231 and at least one driven blade 232, the driving motor 234 is drivingly connected to the driving blade 231, and the driven blade 232 is connected to the driving blade 231 through a connecting rod 233; thus, when the driving motor 234 drives the driving blade 231 to rotate, all the driven blades 232 can be driven to rotate through the connecting rod 233, so that on one hand, the driving motor 234 does not need to be arranged corresponding to each air guiding blade 23, and on the other hand, all the air guiding blades 23 can synchronously rotate, and the air outlet directions of all the positions of the air outlet 202 are consistent. Generally, the driving blade 231 and the driven blade 232 are pivotally connected to the air outlet 202 on the same side, and are pivotally connected to the connecting rod 233 on the opposite side.
Referring to fig. 11 together, optionally, the air cleaning device 2 further includes a position sensor 4 for detecting a rotation position of the air guiding blade 23, the position sensor 4 is electrically connected to the controller 3, and the controller 3 obtains the rotation position of the air guiding blade 23 through the position sensor 4 and controls the output shaft of the driving motor 234 to stop rotating when the air guiding blade 23 rotates to the preset position. Through the additional arrangement of the position sensor 4, the air guide blades 23 can be controlled at the preset positions conveniently, and the air guide direction of the air purification device 2 can be controlled accurately. Of course, in some other embodiments, the position sensor 4 may not be provided, for example, when the driving motor 234 is a stepping motor, the rotation position of the wind guiding blade 23 may be controlled by controlling the rotation angle or the rotation number of the output shaft thereof; it can be understood that, under the condition that the radius ratio of the first gear 235 to the second gear 236 is determined, there is an exact corresponding relationship between the rotation angle or the number of rotations of the output shaft of the driving motor 234 and the rotation angle of the air guiding blade 23, the target rotation angle or the target number of rotations of the output shaft of the driving motor 234 can be obtained according to the corresponding relationship and the rotation angle required by the air guiding blade 23, and then the output shaft of the driving motor 234 is controlled to rotate according to the target rotation angle or the target number of rotations.
Optionally, the position sensor 4 is a microswitch set. For example, the micro switch set may include a first micro switch 41 and a second micro switch 42 (see fig. 9) that are disposed on the air outlet 202 and are respectively disposed on two opposite sides of the air guiding blade 23, where the preset position includes a preset first position and a preset second position, and when the air guiding blade 23 rotates to trigger the first micro switch 41, the air guiding blade 23 is located at the preset first position; when the air guiding blade 23 rotates to trigger the second microswitch 42, the air guiding blade 23 is in the preset second position. For the solution provided with the connecting rod 233, the first micro switch 41 and the second micro switch 42 may be correspondingly disposed on two opposite sides of one wind guiding blade 23, for example, only on two opposite sides of the active blade 231, so as to make the structure of the product simpler. It can be understood that when the first microswitch 41 is triggered, the first microswitch 41 will send a first position signal to the controller 3, and when the controller 3 receives the first position signal, it is determined that the air guiding blade 23 has rotated to the preset first position; when the second microswitch 42 is triggered, the second microswitch 42 will send a second position signal to the controller 3, and the controller 3 determines that the air guiding blade 23 has rotated to the preset second position when receiving the second position signal. However, the design is not limited thereto, and in other embodiments, the position sensor 4 may be configured as a hall sensor. It can be understood that the micro switch has a price advantage, and the hall sensor can acquire any rotating position of the air guide blade 23.
Optionally, the range hood further comprises a mode control device, and the controller 3 is electrically connected with the mode control device. The controller 3 is configured to control the driving motor 234 to drive the air guiding blade 23 to rotate to the preset first position according to a first mode instruction of the mode control device, and control the driving motor 234 to drive the air guiding blade 23 to rotate to the preset second position according to a second mode instruction of the mode control device. It can be understood that, when the air guiding blade 23 is in the preset first position, the air outlet 202 has a first air outlet direction; when the air guiding blade 23 is located at the predetermined second position, the air outlet 202 has a second air outlet direction different from the first air outlet direction. In this technical scheme, the user can realize through mode control device that air outlet 202 is in the switching of first air-out direction and second air-out direction.
Alternatively, referring to fig. 1, the mode control device is provided with a mode control key 5, so that the user can conveniently change the air outlet direction of the air purification device 2 by simply pressing the key. However, the design is not limited thereto, and in other embodiments, the mode control device may also be a remote control signal receiver for receiving the first mode command and the second mode command sent by the remote controller, so that the user can switch the two modes through the remote controller; or, the mode control device may also be a wireless communication module to receive the first mode command and the second mode command sent by the external terminal, so that the user can switch the two modes through the APP on the external terminal.
Alternatively, referring to fig. 1, 8 and 10, the air outlet 202 is located on the front surface of the air purification apparatus 2, and the length direction of the air guiding blade 23 is transverse; when the air guide blade 23 is in the preset first position, the air guide blade 23 extends obliquely upward in the width direction, and when the air guide blade 23 is in the preset second position, the air guide blade 23 extends obliquely downward in the width direction or horizontally forward. It can be understood that when the air guide blades 23 extend obliquely forward and upward, the air outlet 202 blows air obliquely forward and upward, and the purified wind energy output obliquely forward and upward pushes the oil smoke at the upper half part of the kitchen space to flow downward so as to be brought into air circulation purification, thereby further reducing the oil smoke in the kitchen and being beneficial to improving the overall air quality of the kitchen space; in particular, the upper half of the kitchen space is often subject to soot accumulation due to the thermal plume action of the soot. And when wind guide blade 23 extends towards the lower side of the front in an inclined manner or extends towards the front in a horizontal manner, air outlet 202 exhausts air towards the lower side of the front in an inclined manner or exhausts air towards the front in a horizontal manner so as to blow purified clean air to a cooker, so that clean air is provided for the cooker, and user experience is improved.
Referring also to fig. 11, optionally, the controller 3 is further electrically connected to the cleaning fan 21 of the air cleaning device 2, and the controller 3 is configured to control the cleaning fan 21 to operate at a first rotation speed according to the first mode command and control the cleaning fan 21 to operate at a second rotation speed according to the second mode command; the first rotational speed is greater than the second rotational speed. In this embodiment, under the first mode instruction, the air guiding blade 23 is located at the preset first position to guide air obliquely towards the front upper side, and at this time, the controller 3 controls the purifying fan 21 to operate at the first higher rotation speed, so that the air outlet 202 obliquely blows air towards the front upper side with a larger air output, and therefore, the air supply distance is longer and the air in the kitchen can be better circularly purified; and under the second mode instruction, the air guiding blade 23 is located at the preset second position to guide air obliquely towards the front lower part or horizontally towards the front, at this time, the controller 3 controls the purifying fan 21 to operate at a smaller second rotating speed, so that the air outlet 202 discharges air obliquely towards the front lower part or horizontally towards the front with a smaller air discharge amount, the air discharge is softer, clean air can be provided for a cooker in a soft and comfortable air supply manner, and user experience is improved.
Further, the air purification device 2 is arranged in the range hood main body 1, so that the appearance parts can be shared conveniently, and the appearance of the range hood is simpler. However, the design is not limited thereto, and in other embodiments, the air purification device 2 may be disposed outside the cigarette maker main body 1 to facilitate maintenance and disassembly of the internal components (such as the filter 22 and the purification fan 21).
