Description

Technical Field

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

[0002] A range hood is a kitchen appliance that purifies the kitchen environment. It is installed above the kitchen stove and can quickly remove the waste from stove combustion and the fumes that are harmful to the human body generated during cooking and discharge them outdoors to prevent the accumulation of fumes from polluting the kitchen environment.

[0003] In the prior art, double-chamber range hoods usually use double-chamber double baffles. The baffle is installed in the smoke collecting chamber, and the baffle moves up and down in the smoke collecting chamber to control the opening and closing of the smoke collecting chamber. A filter for filtering oil smoke is provided around the baffle. The oil smoke enters the smoke collecting chamber through the filter from the side of the baffle, and the grease in the oil smoke adheres to the filter. After long-term use, the filter needs to be cleaned of oil stains attached to the surface to avoid clogging of the filter. Since the filter is set on the side of the baffle and is blocked by the baffle, it is difficult to disassemble, resulting in inconvenience in cleaning.

[0064] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0065] like Figures 1 to 7 As shown, one embodiment of the present invention provides a cleaning device for cleaning a smoke guide assembly, wherein the smoke guide assembly includes a filter 110, and the cleaning device includes a cleaning mechanism 200; the cleaning mechanism 200 includes a brush head 210, and the brush head 210 is connected to the filter 110, and the filter 110 and the brush head 210 can move relative to each other.

[0066] The cleaning device provided in this embodiment is installed at the filter 110 of the smoke guide assembly, and includes a brush head 210 connected to the filter 110. The brush head 210 removes grease attached to the filter 110 through relative movement between the brush head 210 and the filter 110, so as to achieve the purpose of cleaning the filter 110. The movement between the filter 110 and the brush head 210 can be sliding, rotating, or vibrating.

[0067] In this embodiment, the filter 110 may move relative to the brush head 210, or the brush head 210 may move relative to the filter 110, or the filter 110 and the brush head 210 may move relative to each other at the same time.

[0068] like Figure 1 and Figure 3 As shown, the smoke guide assembly further includes a baffle 120 , and the brush head 210 is mounted on the baffle 120 , and the baffle 120 can drive the brush head 210 to move.

[0069] In the cleaning device provided in this embodiment, specifically, the brush head 210 can slide relative to the filter screen 110 to clean the grease attached to the filter screen 110. The brush head 210 and the filter screen 110 are constantly rubbed to clean the grease on the filter screen 110.

[0070] like Figure 4 and Figure 5 As shown, the brush head 210 includes a cleaning portion 211 and a connecting portion 212 , the cleaning portion 211 abuts against the filter 110 , and the connecting portion 212 is connected to the baffle 120 .

[0071] In the cleaning device provided in this embodiment, the connecting portion 212 is connected to the baffle 120 to prevent the brush head 210 from falling during the movement with the baffle 120. The cleaning portion 211 and the filter 110 are specifically abutted, and there is a force between the two to remove the grease attached to the filter 110.

[0072] In this embodiment, the cleaning mechanism 200 includes multiple implementations.

[0073] Embodiment 1

[0074] like Figure 1 , Figure 2 and Figure 5 As shown, the cleaning portion 211 includes first bristles 2111, the connecting portion 212 includes a first mounting block, and the first bristles 2111 are mounted on the first mounting block; the cleaning mechanism 200 includes a power assembly; the output end of the power assembly is connected to the first mounting block; the power assembly drives the first bristles 2111 to vibrate, and / or the power assembly drives the first bristles 2111 to rotate.

[0075] In the cleaning device provided in this embodiment, the power assembly is connected to the brush head 210, and the power assembly can drive the cleaning part 211 to rotate, vibrate, or rotate and vibrate relative to the filter 110, so as to improve the cleaning effect of the cleaning part 211, so that the cleaning part 211 can clean the oil stain quickly and more thoroughly.

[0076] In actual use, the cleaning portion 211 is a brush, and in order to protect the filter 110 and prevent the filter 110 from being worn, the brush is made of soft materials such as polypropylene hair, nylon hair, etc.

[0077] It is understandable that the cleaning portion 211 may also be a scouring pad, etc., which can also achieve the purpose of cleaning the grease attached to the filter 110 in this embodiment.

[0078] It is understandable that the connecting portion 212 is used to fix the bristles, and the connecting portion 212 can also be a structure such as a cable tie, a fixing ring, etc.

[0079] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the cleaning mechanism 200 also includes a shell 220, and the shell 220 is installed on the baffle 120; the power assembly is installed in the shell 220; a mounting hole 221 is provided on the shell 220, the first mounting block is in the mounting hole 221, and the output end of the power assembly is connected to the first mounting block through the mounting hole 221.

[0080] In the cleaning mechanism 200 provided in this embodiment, the housing 220 is used to place the power assembly, provide protection for the power assembly, and also has waterproof and dustproof effects. The first mounting block is connected to the housing 220, and the housing 220 is connected to the baffle 120. The housing 220 and the baffle 120 can be connected by welding, gluing, or riveting.

[0081] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the power assembly includes a sonic motor 231; the output end of the sonic motor 231 is connected to the first mounting block, and the sonic motor 231 drives the first bristles 2111 to vibrate.

[0082] In this embodiment, specifically, the first bristles 2111 vibrate relative to the filter screen 110 , driving the grease in the filter screen 110 to form a small pulse impact force, impacting the narrow gaps, blind spots and sharp corners of the filter screen 110 .

[0083] In actual use, the sonic motor 231 uses a small-volume motor so that the vibration amplitude is within 10°, which does not take up too much space and can achieve a good cleaning effect.

[0084] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the power assembly further includes a shock absorber 232 ; the shock absorber 232 is disposed between the sonic motor 231 and the inner wall of the shell 220 .

[0085] In this embodiment, the shock absorber 232 is arranged between the sonic motor 231 and the inner wall of the housing 220 for shock absorption and sound insulation. The shock absorber 232 can be a spring or a sound insulation cotton. In this embodiment, a spring is used, one end of which abuts against the sonic motor 231, and the other end abuts against the inner wall of the housing 220. By utilizing the characteristics of the spring, the action time of the force is extended, and the purpose of shock absorption is finally achieved. The structure is simple and cost-saving.

[0086] Embodiment 2

[0087] like Figure 3 and Figure 4 As shown, the cleaning portion 211 includes at least two groups of second bristles 2112, and the connecting portion 212 includes a second mounting block, one end of any group of second bristles 2112 is against the filter 110, and the other end is mounted on the second mounting block, and the angle between any two adjacent groups of second bristles 2112 is greater than 0°.

[0088] In this embodiment, the second bristles 2112 abut against the filter screen 110, and the second bristles 2112 move up and down with the baffle 120, and continuously scrape the grease on the filter screen 110 during the movement. At the same time, the angle between two adjacent groups of second bristles 2112 is greater than 0°, that is, the directions of any two adjacent groups of second bristles 2112 are different. By arranging the adjacent second bristles 2112 at an angle, the cleaning part 211 has multiple cleaning angles, and can clean dead corners, meshes, etc.

[0089] like Figure 3 and Figure 4 As shown, the cleaning portion 211 includes a first curved segment 311 and a second curved segment 312, and the first curved segment 311 and the second curved segment 312 each include at least one group of second bristles 2112; one end of the first curved segment 311 abuts against the filter 110, and the other end is connected to the second curved segment 312, and the end of the second curved segment 312 away from the first curved segment 311 abuts against the filter 110; the first curved segment 311 and the second curved segment 312 are connected to form a cleaning portion 211 with a semi-lunar structure.

[0090] In this embodiment, the cleaning portion 211 is a semi-lunar structure having two pointed ends, one of which is the end of the first curved section 311 away from the second curved section 312, and the other pointed end is the end of the second curved section 312 away from the first curved section 311. During the up and down movement of the cleaning portion 211, the two pointed ends are used to continuously scrape and clean the filter 110, so that the sharp corners and mesh holes can be cleaned, and the cleaning effect is good.

[0091] like Figure 3 and Figure 4 As shown, the curvature of the first curved section 311 is smaller than the curvature of the second curved section 312 .

[0092] In this embodiment, the curvature is a numerical value of the curvature of the curve. By setting the first curved section 311 and the second curved section 312 with different curvatures, the filter 110 can be cleaned at multiple angles and dead corners can be cleaned, with excellent cleaning effect.

[0093] like Figure 3 and Figure 4 As shown, an adhesive is provided between the connecting portion 212 and the baffle 120 .

[0094] In this embodiment, the structure of the connection part 212 is the same as that in the first embodiment, and will not be described here. The connection between the connection part 212 and the baffle 120 is adhesively bonded. It has a simple structure, is easy to produce, and has a low cost.

[0095] It can be understood that, in this embodiment, the connecting portion and the baffle may also be snap-connected.

[0096] Specifically, in this embodiment, a slot is provided on the second mounting block, and a flange is provided on the peripheral side of the baffle, and the flange is installed in the slot.

[0097] In actual use, in order to improve the connection strength between the card slot and the flange, an adhesive may be provided between the card slot and the flange.

[0098] At the same time, in this embodiment, since the second bristles 2112 are in contact with the filter 110, when the baffle 120 slides relative to the filter 110, the second bristles 2112 can also limit the baffle 120 to prevent the baffle 120 from shaking left and right during the sliding process.

[0099] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, the cleaning device further includes a flushing mechanism; the flushing mechanism includes a water spray port 411 , and the water outlet direction of the water spray port 411 points to the filter screen 110 .

[0100] The flushing mechanism is used to spray cleaning liquid to the filter screen 110, thereby improving the cleaning effect of the cleaning device on the filter screen 110. It can also prevent oil stains from adhering to the cleaning part 211, and the cleaning part 211 is cleaned while brushing the filter screen 110.

[0101] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, the flushing mechanism includes a water sprayer 410, a water pump 420 and a water tank 430; the water sprayer 410 is installed on the baffle 120, and one end of the water sprayer 410 is provided with the water spray port 411, and the other end is provided with a water inlet connected to the water tank 430; the water pump 420 is arranged between the water tank 430 and the water sprayer 410, and the input end of the water pump 420 is connected to the water tank 430, and the output end of the water pump 420 is connected to the water inlet.

[0102] In the cleaning device provided in this embodiment, the water sprayer 410 moves up and down with the baffle 120, so as to more comprehensively rinse the filter 110. The water pump 420 is used for boosting pressure to increase the pressure of the water when it is sprayed out by the water sprayer 410. During the spraying process, the oil stains are taken away from the filter 110 and the cleaning part 211. The water tank 430 is used to store the cleaning liquid, which can be water or detergent. The number of the water tanks 430 can be one or more. When the number of the water tanks 430 is more than one, the liquid in some of the water tanks 430 is water, and the liquid in other water tanks 430 is detergent.

[0103] In actual use, the water pump 420 uses a carbon brush intelligent permanent magnet motor, which can generate a high-frequency pulse water column of 1500 times per minute, which can rush into the blind area of ​​the mesh of the filter 110 and quickly wash away the accumulated oil residue.

[0104] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, the inner diameter of the water spray port 411 is 0.6-0.8 mm.

[0105] In the cleaning device provided in this embodiment, the inner diameter of the water spray port 411, that is, the diameter of the cross section of the water spray hole, is 0.6-0.8 mm, so that the water flow sprayed by the water sprayer 410 can easily shuttle between the meshes and accurately clean the dead corners of the meshes.

[0106] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, the cleaning device includes a plurality of water sprayers 410 and a plurality of cleaning mechanisms 200 ; and the plurality of water sprayers 410 and the plurality of cleaning mechanisms 200 are arranged at intervals along the periphery of the baffle 120 .

[0107] In the cleaning device provided in this embodiment, the baffle 120 has a smoke guiding function. To filter the oil smoke, the filter 110 is arranged along the circumference of the baffle 120. Therefore, it is necessary to provide a plurality of cleaning mechanisms 200 and a plurality of water sprayers 410 to more comprehensively clean the filter 110. At the same time, in order to save space, the plurality of water sprayers 410 are connected to the water tank 430 in a multi-way manner.

[0108] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, the water sprayer 410 and the cleaning mechanism 200 are arranged in a one-to-one correspondence.

[0109] The cleaning device provided in this embodiment has a one-to-one corresponding arrangement of the water sprayer 410 and the cleaning mechanism 200. Each cleaning mechanism 200 is correspondingly provided with the water sprayer 410. While the cleaning mechanism 200 is scrubbing, the water sprayer 410 flushes the filter 110, which can improve the cleaning efficiency of the cleaning device on the filter 110.

[0110] like Figure 1 and Figure 3 As shown, the cleaning device also includes a power mechanism 130, and the smoke guide assembly also includes a smoke collecting hood 510, and a smoke collecting chamber 520 is formed in the smoke collecting hood 510; the filter 110, the baffle 120 and the power mechanism 130 are all arranged in the smoke collecting chamber 520; the filter 110 is arranged along the circumferential side of the baffle 120, and the power mechanism 130 is connected to the baffle 120, and drives the baffle 120 to move in the smoke collecting chamber 520.

[0111] In this embodiment, specifically, the power mechanism 130 includes a push rod motor 131, and the push rod motor 131 drives the baffle 120 to move up and down, which has a simple structure and is easy to install.

[0112] It is understandable that in this embodiment, a gear and a rack can also be used to cooperate, with the motor driving the gear to rotate, and the gear driving the rack to rise and fall, which can also achieve the purpose of moving the baffle 120 in the smoke hood 510 up and down in this embodiment.

[0113] In this embodiment, if Figure 1 and Figure 3As shown, the power mechanism 130 further includes a motor bracket 132 ; the motor bracket 132 is connected to the inner wall of the smoke collecting chamber 520 ; and the push rod motor 131 is disposed on the motor bracket 132 .

[0114] In this embodiment, the smoke collecting chamber 520 has a complex structure or a small installation space. By providing the motor bracket 132 and installing the push rod motor 131 on the motor bracket 132 , the push rod motor 131 can adapt to different installation environments.

[0115] In this embodiment, if Figures 7 to 11 As shown, for the convenience of users, a plurality of smoke collecting chambers 520 may be provided in the smoke collecting hood 510, and any two of the smoke collecting chambers 520 may be separated by a filter 110. Each of the smoke collecting chambers 520 is provided with a corresponding smoke inlet 530. At the same time, the baffle 120 also controls the opening and closing of the smoke collecting chamber 520 by opening or closing the smoke inlet 530. Users can open the corresponding smoke collecting chamber 520 by themselves according to the usage of the stove, avoiding the simultaneous opening of multiple smoke collecting chambers 520 to occupy the air intake volume, and improving the efficiency of oil fume extraction.

[0116] In this embodiment, if Fig.10 and Fig.11 As shown, preferably, three smoke collecting cavities 520 are formed in the smoke collecting hood 510 ; providing three smoke collecting cavities 520 can meet the usage of most households, and the three smoke collecting cavities 520 are arranged at intervals in the smoke collecting hood 510 .

[0117] In actual use, the smoke collecting chambers 520 on both sides are the same size, while the smoke collecting chamber 520 in the middle is smaller than the smoke collecting chambers 520 on both sides. In existing three-burner stoves, the burners on the left and right sides are usually used for cooking methods such as frying, which produce a large amount of oil smoke, while the burner in the middle is usually used for stewing and produces less oil smoke. Therefore, the smoke collecting chambers 520 on both sides are set larger to absorb the oil smoke generated during the cooking process, while the oil smoke generated in the middle is less, so a smaller smoke collecting chamber 520 is used. Avoid wasting the internal space of the range hood. At the same time, the size of the smoke inlet hole 530 is also adjusted according to the size of the smoke collecting chamber 520, which greatly improves the smoke extraction efficiency of the range hood and avoids wasting resources.

[0118] In this embodiment, the smoke collecting hood 510 includes a top plate 513 and side walls, the side walls are arranged along the circumference of the top plate 513, a smoke collecting chamber 520 is formed between the top plate 513 and the side walls, and the smoke inlet hole 530 is arranged on the top plate 513, wherein the filter 110 can be arranged in a variety of ways.

[0119] Filter 110 first setting method

[0120] In this embodiment, if Fig. 9 As shown, the smoke guide assembly includes two filters 110; the two filters 110 are frame-shaped structures, and the two filters 110 are respectively arranged at the outer edges of the smoke inlet holes 530 located on both sides. Meshes are arranged on the side walls of the filters 110. Since the smoke collecting cavities 520 located on both sides are relatively large and absorb more oil smoke, the two filters 110 are respectively connected to the outer edges of the smoke inlet holes 530 located on both sides. When the two smoke collecting cavities 520 work normally, the grease in the oil smoke is filtered out.

[0121] The second setting method of filter 110

[0122] In this embodiment, the smoke guide assembly includes a filter 110; the filter 110 is a frame-shaped structure, and the filter 110 is arranged at the outer edge of the smoke inlet hole 530 located in the middle.

[0123] In this embodiment, the structure of the filter 110 is exactly the same as that in the previous setting mode, and will not be repeated here. Considering that some regions may prefer stews, the amount of oil smoke produced is less. Therefore, the filter 110 is set at the outer edge of the smoke inlet hole 530 located in the middle, and then three smoke collecting chambers 520 are separated in the smoke collecting 510, which can not only meet the normal needs of the smoke collecting chambers 520 on both sides, but also save the cost of the equipment. Provide more choices for consumers.

In the initial state, the baffle 120 is located at the lower end of the filter 110, and the peripheral side of the baffle 120 is connected to the lower end of the filter 110. At this time, the smoke inlet 530 is closed. When the smoke inlet 530 needs to be opened, the power mechanism drives the baffle 120 to move upward, the baffle 120 is located at the upper end of the filter 110, and the peripheral side of the baffle 120 is connected to the upper end of the filter 110. At this time, the smoke inlet 530 is opened. The smoke enters the smoke inlet 530, and under the action of the baffle 120, the smoke moves around the baffle 120, passes through the filter 110, and enters the smoke collecting chamber 520. When cooking is completed, the power mechanism drives the baffle 120 to move downward, restore to the initial state, and close the smoke inlet 530.

[0125] At the same time, since a cleaning mechanism is provided on the filter 110 , the filter 110 can be cleaned while the smoke inlet 530 is opened or closed.
