Description

Technical Field

[0001] The invention relates to the technical field of kitchen appliances, and in particular to a cleaning structure and a range hood. Background Art

[0002] A lot of oil smoke is generated during cooking. If it cannot be discharged in time, it will affect the cooking process and affect the user's respiratory health. The range hood can effectively remove the oil smoke, so it has gradually become an indispensable kitchen appliance for many users. After the range hood has been used for a period of time, the impeller and the inside of the volute in the suction and exhaust system are often in contact with the oil smoke, which will absorb a lot of oil stains. The longer the time, the more difficult it is to clean the oil stains. If the inner cavity is not cleaned for a long time, the load in the suction and exhaust system will increase, and the performance indicators will decrease, which is specifically reflected in the decrease of suction and the increase of noise. In particular, the oil stains on the impeller, if not cleaned in time, will have a great impact on the performance of the range hood. In addition to the performance degradation, the accumulation of oil stains breeds bacteria, and the residual odor seriously affects the health of users. However, oil stains are a kind of stains that are not easily dissolved by liquids. The range hoods with cleaning functions on the market are limited to simple cleaning liquid spraying, soaking cleaning, or spraying and soaking with heated steam.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0032] like Figure 1 and Figure 2 As shown, one embodiment discloses a cleaning structure, including a moving part 100 and a vibrating part 200, the moving part 100 is connected to the vibrating part 200, the moving part 100 has a first position and a second position, the moving part 100 is used to reciprocate between the first position and the second position, when the moving part 100 is located at the first position, the moving part 100 or the vibrating part 200 is used to contact the wind wheel 10, so that the vibrating part 200 drives the wind wheel 10 to vibrate, when the moving part 100 is located at the second position, the moving part 100 and the vibrating part 200 are spaced apart from the wind wheel 10.

[0033] In the cleaning structure, when the wind wheel 10 needs to be cleaned, the moving member 100 can be moved to the first position, at which time the moving member 100 or the vibrating member 200 is in contact with the wind wheel 10. When the vibrating member 200 vibrates, the wind wheel 10 can be directly driven to vibrate, or the vibrating member 200 drives the wind wheel 10 to vibrate through the moving member 100 in contact with the wind wheel 10, so as to shake off the oil and dust on the wind wheel 10. When the cleaning is completed, the moving member 100 is moved to the second position, so that the moving member 100 and the vibrating member 200 are spaced apart from the wind wheel 10. The moving part 100 and the vibrating part 200 do not affect the rotation of the wind wheel 10, so that the wind wheel 10 can work normally. Therefore, the above-mentioned cleaning structure can realize automatic cleaning of oil and dust on the wind wheel 10. The cleaning method is simple and convenient. No water is required during the cleaning process, which can effectively reduce water consumption. The cleaning process is more environmentally friendly, and there is no need to consider the treatment of wastewater after cleaning. In addition, the contact and separation of the moving part 100 and the vibrating part 200 with the wind wheel 10 can be achieved by controlling the position of the moving part 100, without affecting the normal operation of the wind wheel 10.

[0034] In this specific embodiment, the cleaning structure is mainly used to clean the fan wheel 10 of the range hood, but in other embodiments, the cleaning structure can also be used to clean fans, blowers and other equipment with blades.

[0035] In one embodiment, the vibrating member 200 is an ultrasonic generator. The ultrasonic generator can emit a high-frequency oscillation signal, which is converted into a high-frequency mechanical oscillation by a transducer and propagated, and can cause the wind wheel 10 to vibrate at a high frequency, thereby removing dust or oil from the wind wheel 10 from the surface of the wind blade, and achieving a better decontamination effect.

[0036] In other embodiments, the vibration element 200 may also be a component that generates mechanical vibrations itself.

[0037] In one embodiment, if Figure 1 and Figure 2 As shown, the cleaning structure further comprises a base, a moving member 100 is used to be arranged on a side of the vibrating member 200 close to the wind wheel 10, the base is connected to the vibrating member 200, and the moving member 100 and the base are slidably matched, so that the moving member 100 reciprocates between the first position and the second position. At this time, when the moving member 100 moves to the first position relative to the base, the vibrating member 200 contacts the wind wheel 10 through the moving member 100, and drives the wind wheel 10 to vibrate, so as to shake off the dust or oil on the wind wheel 10, and when the moving member 100 moves to the second position relative to the base, the moving member 100 is separated from the wind wheel 10, and at this time, the moving member 100 and the vibrating member 200 are both spaced apart from the wind wheel 10, and will not affect the normal operation of the wind wheel 10.

[0038] In other embodiments, the vibration member 200 is disposed on a side of the moving member 100 close to the wind wheel 10. When the moving member 100 moves to a first position, the vibration member 200 is in direct contact with the wind wheel 10 to drive the wind wheel 10 to vibrate. When the moving member 100 moves to a second position, the moving member 100 drives the vibration member 200 away from the wind wheel 10 and disengages from the wind wheel 10, which does not affect the normal operation of the wind wheel 10.

[0039] In one embodiment, if Figure 1 and Figure 2 As shown, the base is sleeved outside the moving member 100, and the base and the moving member 100 cooperate to form a telescopic structure 101. At this time, the moving member 100 can realize reciprocating movement between the first position and the second position by telescoping relative to the base, and the movement of the moving member 100 is more stable. After contacting with the wind wheel 10, the base is sleeved outside the moving member 100, and the base can better transmit the vibration of the vibrating member 200 to the moving member 100, and the wind wheel 10 is driven by the moving member 100 to vibrate, and the vibration of the vibrating member 200 has little effect on the cooperation between the base and the moving member 100, and it is not easy to be damaged, so that the above-mentioned cleaning structure has a longer service life.

[0040] Specifically, the telescopic structure 101 may be a cylinder, a linear drive member, etc. In this case, the base is also a power output member that drives the moving member 100 to move between the first position and the second position.

[0041] In other embodiments, the movable member 100 may also be a cam, and the movable member 100 may be rotatably set. The first position and the second position are two positions in the rotation direction of the movable member 100. When the movable member 100 rotates to the first position, the flange of the movable member 100 contacts the wind wheel 10. When the movable member 100 rotates to the second position, the movable member 100 no longer contacts the wind wheel 10.

[0042] In other embodiments, one end of the moving part 100 is hinged to the base, and the other end of the moving part 100 is connected to the base through a cylinder. The two ends of the cylinder are respectively hinged to the moving part 100 and the base. At this time, the cylinder can push the moving part 100 to approach the wind wheel 10 and contact with the wind wheel 10, or drive the moving part 100 away from the wind wheel 10.

[0043] In other embodiments, the vibrating member 200 is directly connected to the moving member 100, so that the vibration of the vibrating member 200 is more directly transmitted to the wind wheel 10, thereby improving the cleaning effect.

[0044] In one embodiment, if Figures 1 to 3 As shown, the cleaning structure further includes a first driving member 300, and the vibrating member 200 has a third position and a fourth position. The first driving member 300 is used to drive the vibrating member 200 to reciprocate between the third position and the fourth position. When the vibrating member 200 is located at the third position, the vibrating member 200 can drive the wind wheel 10 to vibrate. When the vibrating member 200 is located at the fourth position, the vibrating member 200 is used to drive the oil net 20 to vibrate. The vibrating member 200 is located at the third position, and the movable member 100 can move between the first position and the second position. When the movable member 100 moves to the first position, the vibrating member 200 can drive the wind wheel 10 to vibrate, so that the wind wheel 10 shakes off dust and oil. Then the movable member 100 moves to the second position, and the vibrating member 200, the movable member 100 and the wind wheel 10 are no longer in contact. The vibrating member 200 is driven by the first driving member 300 to move to the fourth position. At this time, the vibrating member 200 can drive the oil net 20 to vibrate, accelerate the shedding and flow speed of oil and dust on the oil net 20, and realize the cleaning of the oil net 20.

[0045] Specifically, the first driving member 300 drives the vibrating member 200 and the moving member 100 to move back and forth between the third position and the fourth position at the same time.

[0046] like Figure 3 As shown, at this time, the vibration member 200 is located at the third position.

[0047] In one embodiment, if Figures 1 to 3As shown, the cleaning structure further includes a bridge piece 400, which is connected to the vibrating piece 200 and is used to contact the oil net 20. The bridge piece 400 can reduce the moving stroke of the vibrating piece 200, so that the vibrating piece 200 can drive the oil net 20 to vibrate as soon as possible after not driving the wind wheel 10 to vibrate, thereby improving the switching speed of cleaning the wind wheel 10 and the oil net 20.

[0048] In one embodiment, if Figures 1 to 3 As shown, a magnetic member 410 is provided on one side of the bridge member 400 away from the vibrating member 200. When the bridge member 400 is a magnetic member 410, the bridge member 400 will absorb the oil net 20 when in contact with the oil net 20, so as to better transmit the vibration of the vibrating member 200 to the oil net 20, thereby improving the cleaning effect of the oil net 20.

[0049] In other embodiments, a slot is provided on the oil net 20, and the bridging member 400 can be inserted into the slot. By utilizing the limiting fit between the slot and the bridging member 400, the bridging member 400 can better drive the oil net 20 to vibrate.

[0050] In one embodiment, the magnetic member 410 is an electromagnet. When the magnetic member 410 is an electromagnet, the electromagnet can be powered to make it magnetic so as to adsorb the oil net 20 for transmitting vibration. When the cleaning of the oil net 20 is completed, the electromagnet can be powered off, and the magnetism of the electromagnet is weakened or non-magnetic, so that the bridging member 400 can be easily separated from the oil net 20.

[0051] In one embodiment, if Figures 1 to 3 As shown, the cleaning structure further includes a first guide member 500 and a first base 600. The vibrating member 200 and the moving member 100 are both arranged on the first base 600. The first driving member 300 is used to drive the first base 600 to move along the first guide member 500, so that the first base 600 reciprocates between the third position and the fourth position. The first guide member 500 guides the first base 600, so that the movement of the first base 600 is more stable, ensuring that the vibrating member 200 can move to a predetermined position.

[0052] Optionally, the first guide member 500 is arranged in a vertical or approximately vertical direction. Since the oil net 20 is generally located below the wind wheel 10, the first base 600 is driven by the first driving member 300 to move up and down along the first guide member 500, and the vibration member 200 can drive the wind wheel 10 and the oil net 20 to vibrate respectively.

[0053] In other embodiments, the first base 600 can be directly connected to the cylinder, and the cylinder is used to drive the first base 600 to move back and forth linearly between the third position and the fourth position; or a crank slider mechanism, a cam structure, etc. are used to drive the first base 600 to move back and forth linearly between the third position and the fourth position; or a rotating member is provided, one end of the rotating member is hinged to the inside of the range hood, and the first base 600 is provided on the other end of the rotating member, and the rotating member can rotate back and forth between the third position and the fourth position.

[0054] In one embodiment, if Figures 1 to 3 As shown, the first guide member 500 is a screw rod, the first guide member 500 passes through the first base 600 and is threadedly matched with the first base 600, and the first driving member 300 is used to drive the first guide member 500 to rotate, so that the first base 600 moves along the first guide member 500. The first driving member 300 drives the first guide member 500 to rotate, so that the first base 600 and the first guide member 500 cooperate in a manner similar to a screw rod nut, so that the first base 600 moves along the first guide member 500. At this time, the moving position of the first base 600 is more accurately controlled, and the movement of the first base 600 is more stable.

[0055] In other embodiments, the first guide member 500 and the first base 600 may also be fitted in a sliding manner.

[0056] In one embodiment, if Figures 1 to 3 As shown, the first base 600 includes a main body 610, a second driving member 620, a second guide member 630 and a second base 640. The second guide member 630 is arranged on the main body 610, and the second guide member 630 is used to be spaced apart from the wind wheel 10. The vibrating member 200 and the moving member 100 are both arranged on the second base 640, and the second driving member 620 is used to drive the second base 640 to move along the second guide member 630. At this time, the second driving member 620 can be used to drive the second base 640, the vibrating member 200 and the moving member 100 on the second base 640 to move along the second guide member 630, and the positions of the vibrating member 200 and the moving member 100 can be adjusted. In addition, the movement of the second base 640 along the second guide member 630 can be used to enable the vibrating member 200 to contact different positions on the oil net 20 respectively, thereby improving the effect of shaking off the dust and oil on the oil net 20.

[0057] Specifically, the second guide member 630 is arranged in a horizontal or approximately horizontal direction, and the second guide member 630 is arranged vertically or approximately vertically to the central axis of the wind wheel 10. At this time, the second base 640 can move left and right in the horizontal direction.

[0058] In one embodiment, the second guide member 630 is a screw rod, the second guide member 630 passes through the second base 640 and is threadedly matched with the second base 640, the second driving member 620 is disposed on the main body 610, and the second driving member 620 is used to drive the second guide member 630 to rotate, so that the second base 640 moves along the second guide member 630. In this case, the movement control of the second base 640 is more precise, and the movement is more stable.

[0059] In other embodiments, the second base 640 may also be directly driven by a cylinder, a linear drive, or the like to achieve displacement.

[0060] In one embodiment, if Figures 1 to 3 As shown, there are two first guide members 500, which are arranged at intervals, there are two main bodies 610, one main body 610 cooperates with one first guide member 500, and both ends of the second guide member 630 are respectively connected to the two main bodies 610. At this time, the assembly structure of the second guide member 630 and the main body 610 can move along the first guide member 500, and the movement of the second guide member 630 is more stable, and the two ends of the second guide member 630 are respectively connected to the two main bodies 610, the second guide member 630 itself is also more stable, and the guidance of the second base 640 is also more accurate.

[0061] Optionally, one end of the second guide member 630 is hinged to one of the main bodies 610, and the other end of the second guide member 630 is hinged to the other main body 610, so that the second driving member 620 can drive the second guide member 630 to rotate, and the second base 640 can move along the second guide member 630 by using the threaded cooperation between the second guide member 630 and the second base 640. Alternatively, the two ends of the second guide member 630 are respectively fixedly connected to the two main bodies 610, so that the second driving member 620 can push the second base 640 to slide along the second guide member 630.

[0062] Optionally, one of the two first guide members 500 is a screw rod and the other may also be a screw rod. In this case, there are two first driving members 300 to drive the two screw rods respectively, so that the two main bodies 610 move synchronously; or one of the two first guide members 500 is a screw rod and the other is a smooth guide rod, and the guide rod plays a role of guiding and limiting.

[0063] Specifically, a bearing seat is provided at the end of the first guide member 500 so that the first guide member 500 is limited in position and can rotate.

[0064] like Figures 1 to 3 As shown, an embodiment discloses a range hood, comprising a housing 30 , a wind wheel 10 and any one of the cleaning structures described above, wherein the wind wheel 10 is rotatably disposed in the housing 30 .

[0065] In the range hood described above, when it is necessary to clean the impeller 10, the movable member 100 can be moved to the first position, at which time the movable member 100 or the vibrating member 200 is in contact with the impeller 10. When the vibrating member 200 vibrates, the impeller 10 can be directly driven to vibrate, or the vibrating member 200 can drive the impeller 10 to vibrate through the movable member 100 in contact with the impeller 10, so as to shake off the oil and dust on the impeller 10. When the cleaning is completed, the movable member 100 is moved to the second position, so that the movable member 100 and the vibrating member 200 are both spaced apart from the impeller 10. The moving part 100 and the vibrating part 200 do not affect the rotation of the wind wheel 10, so that the wind wheel 10 can work normally. Therefore, the above-mentioned range hood can realize automatic cleaning of oil and dust on the wind wheel 10. The cleaning method is simple and convenient. No water is required during the cleaning process, which can effectively reduce water consumption. The cleaning process is more environmentally friendly and there is no need to consider the treatment of wastewater after cleaning. In addition, the contact and separation of the moving part 100 and the vibrating part 200 with the wind wheel 10 can be achieved by controlling the position of the moving part 100, without affecting the normal operation of the wind wheel 10.

[0066] In one embodiment, if Figure 1 and Figure 2 As shown, the wind wheel 10 includes a fan blade knob 11, and a slot is provided on the fan blade knob 11. When the moving member 100 is located at the first position, the moving member 100 is plugged into the slot. Through the plugging of the moving member 100 into the slot, the moving member 100 and the fan blade knob 11 are closely matched, and the moving member 100 can better transmit vibration to the fan blade knob 11, and then make the fan wheel 10 vibrate as a whole, thereby improving the cleaning effect of the fan wheel 10.

[0067] In other embodiments, the moving member 100 may also be in contact with or plugged into other parts of the wind wheel 10, so that the vibration member 200 drives the wind wheel 10 to vibrate and achieve a cleaning effect.

[0068] In one embodiment, the moving member 100 is rotatably disposed in the housing 30, and an angle sensor is disposed on the moving member 100. The angle sensor can be used to sense whether the posture of the moving member 100 is correct.
