Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of kitchen appliances, and in particular to a range hood. BACKGROUND

[0002] The existing range hood needs to be cleaned regularly after being used for a period of time, but the inner mesh cover arranged on the fan volute inside the range hood is difficult to be cleaned by the user because it is located inside the range hood. The clogging of the mesh holes of the inner mesh cover will greatly affect the smoke suction effect of the range hood, resulting in a decrease in the performance of the range hood. In addition, if the inner mesh cover is clogged for a long time or during the plum rain period, mold will appear inside the range hood, producing an odor, which will be smelled by the user when using the range hood, resulting in a poor user experience.

[0054] To address the issue that cleaning the inner mesh cover of the fan casing in existing range hoods requires additional drive components, leading to increased manufacturing and assembly costs, as well as an increased overall size of the range hood, this invention provides a structure that enables automatic cleaning of the inner mesh cover of the range hood. This prevents a decrease in smoke extraction efficiency and also prevents mold growth and odors caused by clogging of the inner mesh cover. Furthermore, this structure reduces the manufacturing and assembly costs of the range hood and decreases its overall size. The specific structure is illustrated through the following embodiments.

[0055] Example 1

[0056] This embodiment provides a range hood, such as... Figure 1 As shown, the range hood includes a housing 1, a smoke baffle 2, a fan 3, a transmission assembly 4, and a cleaning assembly 5. The housing 1 has a smoke inlet, through which smoke enters and is drawn outdoors by the fan 3. The smoke baffle 2 is located on one side of the housing 1 (i.e., the range hood is a side-draft type) and can rotate relative to the housing 1 to open or close the smoke inlet. The fan 3, transmission assembly 4, and cleaning assembly 5 are all housed inside the housing 1. An inner mesh cover 31 is provided at the air inlet of the fan 3. The two ends of the transmission assembly 4 are connected to the smoke baffle 2 and the cleaning assembly 5, respectively. When the smoke baffle 2 is opened or closed relative to the housing 1, the transmission assembly 4 and the smoke baffle 2 are linked, causing the transmission assembly 4 to move. The transmission assembly 4, in turn, causes the cleaning assembly 5 to move relative to the inner mesh cover 31, thereby cleaning the inner mesh cover 31.

[0057] In this embodiment, the smoke baffle 2 is driven to rotate by a driving component mounted on the smoke machine housing 1. The driving component can be a motor, electric push rod, or other driving components.

[0058] In this embodiment, when the smoke baffle 2 rotates, it can drive the transmission assembly 4 to rotate relative to the smoke machine housing 1. Simultaneously, the rotation of the transmission assembly 4 drives the cleaning assembly 5 to clean the inner mesh cover 31. For example, as... Figure 2 As shown, a mounting base 11 can be provided on the casing 1 of the range hood, and the transmission component 4 is rotatably mounted on the mounting base 11.

[0059] For reference Figures 2-4The transmission component 4 includes a first connecting member 41, which is bent and rotatably connected to the mounting base 11 at the bent position. The first end of the first connecting member 41 is slidably connected to the smoke baffle 2, and the second end of the first connecting member 41 can drive the cleaning component 5 to move. When the smoke baffle 2 rotates, the first end of the first connecting member 41 is driven by the smoke baffle 2 to move towards the outside or inside of the range hood housing 1. Since the first connecting member 41 is rotatably connected to the mounting base 11, this movement of the first connecting member 41 towards the outside or inside of the range hood housing 1 is converted into rotation relative to the mounting base 11. The first connecting member 41 can drive the cleaning component 5 to rotate to clean the inner mesh cover 31. Simultaneously, the first end of the first connecting member 41 slides along the smoke baffle 2, preventing the first connecting member 41 from having a dead angle of rotation, which would prevent the cleaning component 5 from moving and cleaning the inner mesh cover 31. In this embodiment, the shape of the inner mesh cover 31 is adapted to the rotation trajectory of the cleaning component 5, thereby enabling the cleaning component 5 to contact and clean the inner mesh cover 31 when it rotates.

[0060] like Figure 4 As shown, in this embodiment, a groove 21 can be provided on one side of the smoke baffle 2, and the first end of the first connecting member 41 can slide along the groove 21. Exemplarily, a third connecting member 22 can be provided on the smoke baffle 2; optionally, the third connecting member 22 is fixed to the smoke baffle 2 by screws or rivets. Figure 5 As shown, the third connector 22 has a rectangular plate structure, and the third connector 22 has a groove formed by stamping or other processing methods. The groove and the side wall of the smoke baffle 2 form the aforementioned sliding groove 21. An installation hole 221 is provided on the groove wall. The installation hole 221 allows the first end of the first connector 41 to pass through, and the first end of the first connector 41 can be limited by the groove to prevent it from coming out of the sliding groove 21.

[0061] Preferably, an oil drain hole 222 is also provided on the third connector 22. The oil drain hole 222 can inject lubricating oil into the slide groove 21 to ensure that the first end of the first connector 41 slides more smoothly in the slide groove 21 and is not affected by oil stains. On the other hand, when the smoke baffle 2 is opened and the fan 3 is started to smoke, the first connector 41 may be covered with oil droplets, which may enter the slide groove 21 along the first connector 41. At this time, the oil droplets can be discharged through the oil drain hole 222.

[0062] Reference Figure 4 The first end of the aforementioned first connector 41 is provided with a rolling assembly 43, which is rolled within the slide groove 21 and can move along the slide groove 21. For example, as... Figure 6As shown, the rolling assembly 43 includes a rotating shaft 431 and rollers 432. The rotating shaft 431 is fixedly connected to the first end of the first connecting member 41. Two rollers 432 are provided, symmetrically installed on both sides of the rotating shaft 431, and can rotate relative to the rotating shaft 431. Optionally, multiple rollers 432 can be provided on each side of the rotating shaft 431 to improve rolling reliability. This rolling assembly 43 can reduce the friction between the first end of the first connecting member 41 and the slide groove 21, making the sliding of the first connecting member 41 relative to the slide groove 21 smoother.

[0063] It should be understood that the maximum distance between the rollers 432 on both sides of the aforementioned rotating shaft 431 is preferably greater than the width of the mounting hole 221. Therefore, after the first end of the first connector 41 and the rolling assembly 43 are placed in the groove 21, the rolling assembly 43 can be limited by the third connector 22, preventing the first end of the first connector 41 from dislodging from the mounting hole 221. In this embodiment, when assembling the first connector 41, the first end of the first connector 41 is first passed through the mounting hole 221, then the rolling assembly 43 is installed and fixed, and finally the third connector 22 is fixed to the side wall of the smoke baffle 2.

[0064] As another preferred embodiment, the rolling assembly 43 may also include a ball bearing disposed at the first end of the first connector 41. That is, the first end of the first connector 41 and the ball bearing are placed within the groove 21, and the first end of the first connector 41 moves along the groove 21 by the rolling of the ball bearing. It is understood that the diameter of the ball bearing is larger than the width of the mounting hole 221 to prevent the first end of the first connector 41 from dislodging from the mounting hole 221.

[0065] Considering that the inner mesh cover 31 at the air inlet of the fan 3 has a convex spherical structure, in order to ensure that the cleaning component 5 connected to the transmission component 4 can contact the inner mesh cover 31, the transmission component 4 in this embodiment also includes a second connector 42, which can be referred to in detail. Figure 3The first end of the second connector 42 is retractably connected to the second end of the first connector 41, and a first elastic member 44 is provided between the second end of the first connector 41 and the first end of the second connector 42. Taking the opening of the smoke baffle 2 as an example, the second end of the first connector 41 is retractably connected to the first end of the second connector 42. When the smoke baffle 2 rotates from closing the smoke inlet to opening the smoke inlet, the rotation of the smoke baffle 2 drives the first connector 41 to rotate, and the second connector 42 will rotate with it so that the cleaning component 5 moves downward from the top of the inner mesh cover 31. During the operation, since the inner mesh cover 31 is a convex spherical structure, the cleaning component 5 will be subjected to force by the inner mesh cover 31 to drive the second connecting member 42 to move towards the first connecting member 41. At this time, the first elastic member 44 is compressed. As the cleaning component 5 continues to move to the center of the inner mesh cover 31, the first elastic member 44 is in the maximum compression state. Then the cleaning component 5 continues to move downward. At this time, the elastic force of the first elastic member 44 will push the second connecting member 42 towards the inner mesh cover 31, so that the cleaning component 5 is always in contact with the inner mesh cover 31, thereby achieving comprehensive cleaning from top to bottom.

[0066] Preferably, in this embodiment, an outer sleeve 45 is provided on the first connecting member 41, and an inner sleeve 46 is provided on the second connecting member 42. One end of the inner sleeve 46 extends and retracts inside the outer sleeve 45. The first elastic member 44 is disposed between the inner sleeve 46 and the outer sleeve 45. Exemplarily, one end of the first elastic member 44 is connected to the outer sleeve 45, and the other end is connected to the inner sleeve 46. Of course, both ends of the first elastic member 44 can also abut between the outer sleeve 45 and the inner sleeve 46. Through the extension and retraction connection structure of the inner sleeve 46 and the outer sleeve 45 and the provision of the first elastic member 44, the elastic extension and retraction of the second connecting member 42 relative to the first connecting member 41 can be realized, thereby ensuring that the cleaning component 5 is always in contact with the inner mesh cover 31. In this embodiment, the lengths of the inner sleeve 46 and outer sleeve 45 in their free state (i.e., the state in which the inner sleeve 46 is fully extended relative to the outer sleeve 45) represent the maximum travel distance of the second connecting member 42 relative to the first connecting member 41. The lengths of the inner sleeve 46 and outer sleeve 45 in their compressed state (i.e., the state in which the inner sleeve 46 is fully retracted relative to the outer sleeve 45) represent the minimum travel distance of the second connecting member 42 relative to the first connecting member 41. These maximum and minimum travel distances vary depending on the model of the range hood. Alternatively, in this embodiment, the second connecting member 42 may connect to the outer sleeve 45, and the first connecting member 41 may connect to the inner sleeve 46.

[0067] Furthermore, to ensure the stability of the compression and ejection of the first elastic element 44, guide posts can be provided inside the inner sleeve 46 and the outer sleeve 45. The first elastic element 44 can be a spring, which is sleeved on the guide post and guided by the guide post. In addition, when the inner sleeve 46 is fully retracted into the outer sleeve 45, the ends of the guide posts on the two sleeves can abut against each other to protect the spring from being over-compressed. Of course, a guide post can also be provided on only one of the inner sleeve 46 and the outer sleeve 45.

[0068] It should be noted that in this embodiment, the second connector 42 itself may have an elastic telescopic function. That is, the first end of the second connector 42 is connected to the second end of the first connector 41, the second end of the second connector 42 is equipped with a cleaning component 5, and the middle position of the second connector 42 is provided with an elastic telescopic structure. The elastic telescopic structure may be the cooperation structure of the first elastic element 44, the outer sleeve 45 and the inner sleeve 46, or other structures that can realize the elastic telescopic function of the second connector 42.

[0069] In this embodiment, the cleaning component 5 and the second end of the second connector 42 can be connected by a universal joint 6. This universal joint 6 allows the cleaning component 5 to swing relative to the second connector 42. Specifically, when the cleaning component 5 moves from the top to the bottom or from the bottom to the top of the inner mesh cover 31, and is blocked by the inner mesh cover 31, the cleaning component 5 can rotate via the universal joint 6 to contact the inner mesh cover 31, thus preventing jamming during movement. Furthermore, it allows the angle between the cleaning component 5 and the tangential direction of the inner mesh cover 31 to be more conducive to cleaning the inner mesh cover 31. Preferably, the angle at which the cleaning component 5 swings relative to the second connector 42 is between -45° and +45°. This angle setting allows for better contact between the cleaning component 5 and the inner mesh cover 31, and more effective cleaning of the inner mesh cover 31.

[0070] like Figure 7 and Figure 8 As shown, the cleaning component 5 includes a cleaning bracket 51 and a cleaning brush 52. The cleaning bracket 51 is connected to the universal joint 6, and the cleaning brush 52 is mounted on the cleaning bracket 51 for cleaning the inner mesh cover 31. Preferably, the contact surface between the cleaning brush 52 and the inner mesh cover 31 is similar in shape to the inner mesh cover 31, i.e., the cleaning brush 52 is designed to mimic the shape of the inner mesh cover 31, allowing for better contact and enhanced cleaning effect. Furthermore, the cleaning brush 52 is detachably mounted on the cleaning bracket 51, facilitating easy replacement.

[0071] In this embodiment, a second elastic element 53 is provided between the cleaning bracket 51 and the cleaning brush 52. This second elastic element 53 can be a flexible spring, which can buffer the cleaning brush 52. Combined with the universal joint 6, it ensures that the surface coating of the inner mesh cover 31 is not damaged while cleaning the surface of the inner mesh cover 31. Preferably, multiple second elastic elements 53 are provided, and the multiple second elastic elements 53 are equally spaced between the cleaning bracket 51 and the cleaning brush 52.

[0072] As a preferred technical solution, such as Figure 8 As shown, the cleaning brush 52 includes a mounting portion 521 and bristles 522. The mounting portion 521 has a U-shaped structure, and the cleaning bracket 51 and the second elastic member 53 are placed inside the U-shaped structure, thereby allowing relative sliding between the cleaning brush 52 and the cleaning bracket 51. Furthermore, a limiting portion 5211 is provided at the end of the U-shaped structure, which can abut against the end face of the cleaning bracket 51 to prevent the cleaning brush 52 from detaching from the cleaning bracket 51 during sliding.

[0073] Preferably, the overall width of the bristles 522 should be greater than or equal to the maximum width of the inner mesh cover 31, so that when the cleaning brush 52 moves relative to the inner mesh cover 31, it can be ensured that the bristles 522 can fully contact the inner mesh cover 31 to achieve a thorough cleaning of the inner mesh cover 31.

[0074] As a preferred technical solution, the range hood housing 1 in this embodiment has one flue gas inlet, with a corresponding smoke baffle 2, and two sets of transmission components 4. These two sets of transmission components 4 are located on opposite sides of the smoke baffle 2, and one end of the second connecting member 42 of each set of transmission components 4 is connected to both ends of the cleaning bracket 51 of the cleaning component 5 to drive the cleaning component 5. Alternatively, only one transmission component 4 can be provided, which can also drive the cleaning component 5 to clean the inner mesh cover 31.

[0075] In this embodiment, the range hood also includes an ozone generator 7, which is disposed inside the range hood housing 1. When the user does not use the range hood for an extended period, the ozone generator 7 activates to disinfect and sterilize the interior of the range hood, effectively preventing mold growth and odors. Specifically, a preset time can be set; if the range hood is not used within this preset time, the range hood controller will activate the ozone generator 7.

[0076] In this embodiment, when the range hood is in use, the smoke baffle 2 is first driven by the drive component to open the smoke inlet. During the opening process, please refer to... Figure 1The baffle plate 2 moves one end of the first connecting member 41. As the first connecting member 41 moves within the slide groove 21, it rotates relative to the range hood housing 1. This rotation of the first connecting member 41 causes the second connecting member 42 and the cleaning component 5 to rotate. At this time, the cleaning component 5 moves from the top to the bottom of the inner mesh cover 31 to clean it. During the movement of the cleaning component 5, the cleaning brush 52 swings via the universal joint 6 to maintain constant contact with and clean the inner mesh cover 31. When the range hood is finished being used, if... Figure 9 As shown, the driving component drives the smoke baffle 2 to close the smoke inlet. At this time, the first connecting member 41 rotates relative to the range hood housing 1. The rotation of the first connecting member 41 drives the second connecting member 42 and the cleaning component 5 to rotate. At this time, the cleaning component 5 moves from the bottom to the top of the inner mesh cover 31 to clean the inner mesh cover 31 again. By opening and closing the smoke inlet through the smoke baffle 2, the inner mesh cover 31 can be cleaned twice, resulting in a better cleaning effect. There will be little or no dirt or grease residue on the inner mesh cover 31, thus preventing the mesh of the inner mesh cover 31 from being blocked, improving the smoke extraction effect, and reducing the generation of mold.

[0077] Example 2

[0078] The difference between the range hood provided in this embodiment and that in embodiment one is that the range hood in this embodiment is a top-mounted range hood, and the baffle plate 2 rises and falls relative to the range hood housing 1, so the corresponding transmission component 4 is also different.

[0079] Specifically, such as Figure 10 As shown, the drive component on the range hood in this embodiment can drive the baffle plate 2 to rise and fall, so as to open and close the smoke inlet. When the baffle plate 2 rises and falls, it can drive the transmission component 4 to rise and fall relative to the range hood housing 1. In turn, the transmission component 4 drives the cleaning component 5 to move from one end of the inner mesh cover 31 to the other end, thereby cleaning the inner mesh cover 31.

[0080] In this embodiment, as Figure 11 As shown, the transmission assembly 4 includes a first connecting member 41, which is slidably connected to the range hood housing 1 along the longitudinal direction. Specifically, a slide rail can be provided on the range hood housing 1, and a slider can be provided on one side of the first connecting member 41. The slider slides on the slide rail, thereby realizing the sliding of the first connecting member 41 relative to the range hood housing 1. The first end of the first connecting member 41 is connected to the smoke baffle 2 and can be driven to rise and fall by the smoke baffle 2.

[0081] In addition, the transmission assembly 4 also includes a second connector 42. The first connector 41 has an inverted L-shaped structure, with one end of its long side being the first end and one end of its short side being the second end. The second end of the first connector 41 is connected to the first end of the second connector 42. The second end of the second connector 42 is equipped with a cleaning component 5.

[0082] An inner sleeve 46, an outer sleeve 45, and a first elastic member 44 are provided between the second end of the first connector 41 and the first end of the second connector 42. Their structure and principle are the same as in Embodiment 1 and will not be described again. The connection structure and principle between the second connector 42 and the cleaning component 5 are also the same as in Embodiment 1 and will not be described again.

[0083] In this embodiment, preferably, the fan 3 has two air inlets, symmetrically arranged on both sides of the fan 3. Correspondingly, two flue gas inlets are provided at the casing 1 of the fan, and each flue gas inlet is provided with a baffle plate 2. Each baffle plate 2 is connected to a set of transmission components 4. In other optional embodiments, the flue gas inlet of the casing 1 of the fan can also be provided, in which case there is a corresponding baffle plate 2. The baffle plate 2 and the two air inlets of the fan 3 are provided with transmission components 4 on both sides. Each transmission component 4 is provided with a cleaning component 5. The up and down movement of the baffle plate 2 drives the transmission components 4 and the cleaning components 5 on both sides to move, thereby cleaning the inner mesh cover 31 at the two air inlets of the fan. The rest of the structure of this embodiment is the same as that of Embodiment 1, and will not be described again.

[0084] In this embodiment, when the range hood is in use, the drive unit first drives the smoke baffle 2 to rise and open the smoke inlet. During the opening process, the smoke baffle 2 drives the first connecting member 41 to rise. The rise of the first connecting member 41 drives the second connecting member 42 and the cleaning component 5 to rise. At this time, the cleaning component 5 moves from the bottom to the top of the inner mesh cover 31 to clean the inner mesh cover 31. During the movement of the cleaning component 5, the cleaning brush 52 swings through the universal joint 6 to always contact and clean the inner mesh cover 31. When the range hood is finished being used, the drive unit drives the smoke baffle 2 to fall and close the smoke inlet. At this time, the first connecting member 41 falls and drives the second connecting member 42 and the cleaning component 5 to fall. The cleaning component 5 then moves from the top to the bottom of the inner mesh cover 31 to clean the inner mesh cover 31 again. By opening and closing the smoke inlet with the smoke baffle 2, the inner mesh cover 31 can be cleaned twice, resulting in a better cleaning effect. There will be little or no dirt or grease residue on the inner mesh cover 31, which will prevent the mesh of the inner mesh cover 31 from being blocked, improve the smoke extraction effect, and reduce the occurrence of mold.

[0085] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here.
