Description

Technical Field

[0001] The present invention relates to the technical field of range hoods, and in particular to a top-side double-suction range hood. Background Art

[0002] Traditional range hoods usually have a smoke inlet opened separately on the top or side of the casing, so that the oil smoke can only be sucked from one direction, the smoke extraction efficiency is low, and there are certain limitations. For this reason, a top-side double-suction range hood has also appeared on the market, with smoke inlets opened on the top and side of the casing, so that the oil smoke can be sucked from the top and side, and has a better smoke extraction effect. In addition, the top of the casing is usually also provided with an extension extending forward, and a control panel is installed on the front side of the extension, so that the smoke collection effect can be improved, the oil smoke is prevented from flowing upward, and the range hood can be controlled through the control panel.

[0003] However, existing top-side double-suction range hoods usually only have a movable panel installed at the side smoke inlet, while the top smoke inlet is in an open state. This structure makes it easy for mosquitoes and the like to enter the smoke collecting chamber through the top smoke inlet, and the odor generated by the grease and oil smoke accumulated in the smoke collecting chamber is also easy to seep out from the open top smoke inlet, which not only causes serious pollution to the indoor environment, but also harms human health.

[0004] In addition, although the extension part can conveniently improve the smoke collection effect and control the range hood, when the range hood is not in use, since the extension part is extended forward relative to the casing, it is easy to cause the overall size of the range hood to be too large, which not only occupies the kitchen space, but also easily causes the risk of head collision, causing inconvenience to the user. Summary of the invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a top-side double-suction range hood, which can close the top smoke inlet and the side smoke inlet when not in use, and reduce the overall volume of the range hood.

[0006] According to an embodiment of the present invention, a top-side double-suction range hood comprises: a casing having a smoke collecting chamber, a front wall of the casing being provided with a top smoke inlet and a side smoke inlet which are connected to the smoke collecting chamber, the top smoke inlet being located above the side smoke inlet; a movable plate rotatably mounted on the casing, the movable plate being able to rotate upward to an unfolded position relative to the casing, or the movable plate being able to rotate downward to a folded position relative to the casing; a control mechanism comprising a first control unit and a second control unit, the first control unit being arranged on the front side surface of the movable plate, and the second control unit being arranged on the lower side surface of the movable plate; an actuator being arranged on the casing and being electrically connected to the first control unit and the second control unit Then, the actuator is capable of executing the instructions input by the first control unit and the second control unit; wherein, when the movable plate is located at the unfolded position, the movable plate simultaneously opens the top smoke inlet and the side smoke inlet, the first control unit is arranged toward the top of the casing, the second control unit is arranged toward the front of the casing, and the second control unit is capable of controlling the operation of the actuator; when the movable plate is located at the folded position, the movable plate simultaneously closes the top smoke inlet and the side smoke inlet, the first control unit is arranged toward the front of the casing, the second control unit is arranged toward the bottom of the casing, and the first control unit is capable of controlling the operation of the actuator.

[0037] Reference Figures 1 to 7 One embodiment of the present invention provides a top-side double-suction range hood, comprising a housing 100, a movable plate 200, a control mechanism and an actuator. The housing 100 has a smoke collecting chamber 110. The front wall of the housing 100 is provided with a top smoke inlet 120 and a side smoke inlet 130 connected to the smoke collecting chamber 110. The top smoke inlet 120 is located above the side smoke inlet 130. The movable plate 200 is rotatably mounted on the housing 100. The movable plate 200 can be rotated upward relative to the housing 100 to an unfolded position, or the movable plate 200 can be rotated downward relative to the housing 100 to a folded position. The control mechanism comprises a first control unit 210 and a second control unit 220. The first control unit 210 is disposed on the front side surface of the movable plate 200, and the second control unit 220 is disposed on the lower side surface of the movable plate 200. The actuator is provided in the housing 100 and is electrically connected to the first control unit 210 and the second control unit 220. The actuator can execute the instructions input by the first control unit 210 and the second control unit 220. When the movable plate 200 is in the unfolded position, the movable plate 200 simultaneously opens the top smoke inlet 120 and the side smoke inlet 130, the first control unit 210 is arranged toward the top of the housing 100, and the second control unit 220 is arranged toward the front of the housing 100, and the second control unit 220 can control the operation of the actuator; when the movable plate 200 is in the folded position, the movable plate 200 simultaneously closes the top smoke inlet 120 and the side smoke inlet 130, the first control unit 210 is arranged toward the front of the housing 100, and the second control unit 220 is arranged toward the bottom of the housing 100, and the first control unit 210 can control the operation of the actuator.

[0038] In the top-side double-suction range hood of the embodiment of the present invention, the movable plate 200 can be rotated upward to the unfolded position relative to the casing 100, and the top smoke inlet 120 and the side smoke inlet 130 can be opened at the same time. The movable plate 200 can also be rotated downward to the folded position relative to the casing 100, and the top smoke inlet 120 and the side smoke inlet 130 can be closed at the same time. Thereby, the top smoke inlet 120 and the side smoke inlet 130 can be opened and closed at the same time, which can improve the smoke suction effect conveniently and effectively prevent mosquitoes from entering the smoke collecting chamber 110 through the top smoke inlet 120 or the side smoke inlet 130, and effectively prevent the odor generated by the grease and oil smoke accumulated in the smoke collecting chamber 110 from overflowing from the top smoke inlet 120 or the side smoke inlet 130, thereby maintaining a good indoor environment and reducing the impact of the odor generated by oil and grease on human health.

[0039] In addition, by arranging the first control unit 210 and the second control unit 220 on the movable plate 200, when the range hood is in use, the movable plate 200 can be flipped upward from the folded position to the unfolded position, and the bottom side surface of the movable plate 200 can follow the movable plate 200 to flip upward to the front side of the casing 100, so that the second control unit 220 is arranged toward the front side of the casing 100. At this time, the movable plate 200 extends forward relative to the casing 100, thereby preventing oil smoke from overflowing upward and achieving a smoke collection effect, and the user can control the operation of the actuator through the second control unit 220, thereby controlling the operation of the range hood. When the range hood is not needed, the movable plate 200 can be flipped downward from the unfolded position to the folded position, and the front surface of the movable plate 200 follows the movable plate 200 to flip downward to the front side of the casing 100, so that the first control unit 210 is arranged toward the front side of the casing 100, thereby greatly reducing the overall volume of the range hood, which is beneficial to reducing the kitchen space occupied by the range hood and reducing the risk of head collisions. This can greatly reduce the impact of the range hood on the user when not in use, and the user can control the operation of the actuator through the first control unit 210, thereby controlling the operation of the range hood, making the use of the range hood more convenient.

[0040] Compared with the prior art, the top-side double-suction range hood of the embodiment of the present invention eliminates the extension portion extending forward relative to the casing 100 and the movable panel for controlling the opening and closing of the side smoke inlet 130 in the traditional range hood, and directly achieves the effect of the extension portion and the movable panel through the movable plate 200, which not only greatly reduces the volume of the range hood when not in use, but also can open or close the top smoke inlet 120 and the side smoke inlet 130 at the same time, eliminates the traditional open smoke inlet, can effectively prevent mosquitoes from entering the smoke collecting chamber 110 and effectively prevent the leakage of odor in the smoke collecting chamber 110, thereby greatly improving the user experience.

[0041] It is understandable that the front side of the housing 100 specifically refers to the side of the housing 100 facing the user when the range hood is in use, so that when the range hood is in use, the movable panel 200 is located in the unfolded position and the second control unit 220 faces the user, so that the user can conveniently control the operation of the range hood through the second control unit 220. When the range hood is not in use, the movable panel 200 is located in the folded position and the first control unit 210 faces the user, so that the user can conveniently control the operation of the range hood through the first control unit 210.

[0042] It is understandable that the first control unit 210 and the second control unit 220 can specifically be touch screen control keys or buttons arranged on the surface of the movable plate 200. In addition, the first control unit 210 and the second control unit 220 can also be set as other control structures, which is not specifically limited by the present invention.

[0043] Reference Figures 1 to 9 In some embodiments, the actuator includes a driving device, which is disposed in the smoke collecting chamber 110 and is transmission-connected to the movable panel 200; when the movable panel 200 is in the unfolded position, the second control unit 220 can control the driving device to drive the movable panel 200 to rotate downward to the folded position relative to the housing 100; when the movable panel 200 is in the folded position, the first control unit 210 can control the driving device to drive the movable panel 200 to rotate upward to the unfolded position relative to the housing 100.

[0044] In the above structure, the driving device is electrically connected to the first control unit 210 and the second control unit 220. Therefore, when the range hood is turned off, the movable plate 200 is in the folded position. At this time, the first control unit 210 is arranged toward the front of the casing 100, that is, the first control unit 210 is facing the user. Therefore, when the range hood needs to be used, the user can control the driving device to work through the first control unit 210 and drive the movable plate 200 to rotate upward from the folded position to the unfolded position, so that the second control unit 220 is arranged toward the front of the casing 100, that is, the second control unit 220 is facing the user, and the first control unit 210 is facing the top of the casing 100. Therefore, during the use of the range hood, the user can control the operation of the range hood through the second control unit 220. When the range hood needs to be turned off, the user can also control the driving device through the second control unit 220 and drive the movable plate 200 to rotate downward from the unfolded position to the folded position, thereby making the user's operation more convenient.

[0045] Reference Figures 1 to 9In some embodiments, the driving device includes a rotating shaft 230, a motor 240, and a gear assembly 250. The rotating shaft 230 is rotatably mounted on the housing 100 and connected to the movable plate 200; the motor 240 is mounted in the smoke collecting chamber 110 and is electrically connected to the first control unit 210 and the second control unit 220; the gear assembly 250 is mounted between the motor 240 and the rotating shaft 230, and the motor 240 can drive the rotating shaft 230 to rotate through the gear set, and drive the movable plate 200 to rotate relative to the housing 100 to the unfolded position or the folded position.

[0046] By adopting the above structure, the motor 240 drives the rotation of the rotating shaft 230 by driving the gear assembly 250, thereby driving the movable plate 200 to rotate between the unfolded position and the folded position, so that the flipping of the movable plate 200 is more flexible and smooth, and the setting of the gear assembly 250 can also facilitate the installation of the motor 240, so that the selection of the installation position of the motor 240 in the smoke collecting chamber 110 is more flexible and convenient.

[0047] Reference Figures 1 to 9 The gear assembly 250 specifically includes a driving gear 251 and an output gear 252. The driving gear 251 is installed on the output shaft of the motor 240, and the output gear 252 is set on the rotating shaft 230 and arranged coaxially with the rotating shaft 230. The driving gear 251 and the output gear 252 are meshed with each other. Therefore, when the motor 240 drives the driving gear 251 to rotate, it can drive the output gear 252 to rotate synchronously, thereby driving the rotating shaft 230 to rotate and realizing the flipping of the movable plate 200.

[0048] It can be understood that in order to realize the rotation of the rotating shaft 230, in addition to the driving gear 251 and the output gear 252 being meshed with each other, at least one driven gear can also be set between the driving gear 251 and the output gear 252, thereby making the structure of the driving mechanism more compact and precise, facilitating the accurate flipping of the movable plate 200, and also being able to more flexibly adjust the installation position of the motor 240.

[0049] It is understandable that the output gear 252 is disposed on the rotating shaft 230. Specifically, the output gear 252 can be fixedly mounted on the rotating shaft 230, or the output gear 252 and the rotating shaft 230 can also be configured as an integrally formed structure, which is not specifically limited in the present invention.

[0050] Reference Figures 1 to 9 In some embodiments, the rotating shaft 230 is installed in the smoke collecting chamber 110, and two upwardly protruding connecting ears 260 are provided on the top of the movable plate 200. The two connecting ears 260 are arranged at intervals along the length direction of the movable plate 200 and are connected to the two ends of the rotating shaft 230 one by one.

[0051] By adopting the above structure, the rotating shaft 230 can be confined inside the smoke collecting chamber 110, thereby not only protecting the rotating shaft 230 and reducing the risk of damage to the rotating shaft 230, but also preventing the rotating shaft 230 from being exposed outside the casing 100 and affecting the overall aesthetics of the range hood. By providing two connecting ears 260 on the top of the movable plate 200 and installing the two connecting ears 260 at both ends of the rotating shaft 230, the installation and fixation between the movable plate 200 and the rotating shaft 230 can be facilitated, making the flipping of the movable plate 200 more stable.

[0052] It is understandable that, referring to Figure 5 In some embodiments, the connection between the connecting ear 260 and the rotating shaft 230 can be specifically connected by a screw fastener (not shown in the figure), and the screw fastener is sequentially inserted into the connecting ear 260, the housing 100 and the end surface of the rotating shaft 230, thereby the connecting ear 260 and the rotating shaft 230 can be installed and fixed, the structure is simple and the installation is convenient, and the stable flipping of the movable plate 200 can also be achieved. Of course, in addition to the screw fastener, the connecting ear 260 and the rotating shaft 230 can also be connected by a clamping structure or a welding structure, which is not specifically limited by the present invention.

[0053] Reference Figures 1 to 8 In some embodiments, when the movable panel 200 is located at the unfolded position, the movable panel 200 is arranged horizontally.

[0054] By adopting the above structure, when the movable plate 200 is in the unfolded position, a better smoke collection effect can be achieved, and the horizontal arrangement of the movable plate 200 can also reserve a larger operating space under the movable plate 200, which is convenient for users to perform operations such as cooking, and is not easy to interfere with and affect the user's operations.

[0055] Further, see Figures 1 to 8 In some embodiments, a second lighting device 270 electrically connected to the second control unit 220 is disposed on the rear surface of the movable panel 200. When the movable panel 200 is in the unfolded position, the second lighting device 270 is arranged toward the bottom of the housing 100, and the second control unit 220 can control the second lighting device 270 to turn on or off.

[0056] In the above structure, by setting the second lighting device 270 on the rear surface of the movable plate 200, when the movable plate 200 is flipped to the unfolded position, the movable plate 200 extends forward. At this time, the second control unit 220 is arranged toward the front of the casing 100, and the second lighting device 270 is arranged toward the bottom of the casing 100. This makes it convenient for the user to control the opening or closing of the second lighting device 270 through the second control unit 220. When the second lighting device 270 is turned on, it can provide lighting for the stove, which is convenient for the user to perform cooking and other operations.

[0057] Reference Figure 3 and Figure 4 In some embodiments, a mounting cavity 201 is provided in the movable panel 200, and the second lighting device 270 is installed in the mounting cavity 201, and the light emitting portion of the second lighting device 270 is located on the rear surface of the movable panel 200. In this structure, the provision of the mounting cavity 201 can not only facilitate the installation and accommodation of the second lighting device 270, but also accommodate the wire structure of the second lighting device 270, making the installation of the second lighting device 270 more convenient and protecting the second lighting device 270. In addition, the provision of the mounting cavity 201 can also reduce the weight of the movable panel 200, making the flipping of the movable panel 200 more flexible and convenient.

[0058] Reference Figures 1 to 8 In some embodiments, the top-side double-suction range hood further includes an air duct cover 300, which is disposed above the casing 100, and a first lighting device 310 electrically connected to the first control unit 210 is disposed on the lower surface of the air duct cover 300; when the movable panel 200 is located in the unfolded position, the movable panel 200 is located below the first lighting device 310 and blocks the first lighting device 310, and the movable panel 200 extends forward to the front side of the air duct cover 300; when the movable panel 200 is located in the folded position, the first control unit 210 can control the first lighting device 310 to be turned on or off.

[0059] In the above structure, by arranging the first lighting device 310 on the lower surface of the air duct cover 300, when the movable plate 200 is in the unfolded position, the movable plate 200 extends forward to the front side of the air duct cover 300, thereby achieving a good smoke blocking and smoke collecting effect, and since the movable plate 200 blocks the first lighting device 310, the second lighting device 270 can be controlled to be turned on or off by the second control unit 220, thereby illuminating the stove top by the second lighting device 270. When the movable plate 200 is flipped downward from the unfolded position to the folded position, the movable plate 200 no longer extends to the front side of the air duct cover 300 and does not block the first lighting device 310, at this time, not only can the overall volume of the range hood be greatly reduced, and the risk of head collision can be reduced, in addition, the user can also control the first lighting device 310 to be turned on or off by the first control unit 210 as needed, thereby, when the range hood is not in use, the user can provide lighting for the stove top through the first lighting device 310, which is convenient for the user to prepare food, clean the stove top, etc. It can be seen that by adopting the top-side double-suction range hood of the embodiment of the present invention, the range hood can provide lighting function for the user both in use and non-use states, and is very easy to operate, which greatly improves the user experience.

[0060] In some embodiments, the actuator also includes a fan installed in the air duct cover 300, and the casing 100 is provided with a detection device electrically connected to the first control unit 210 and the second control unit 220, and the detection device is used to detect the position of the movable panel 200; when the movable panel 200 is in the unfolded position, the first control unit 210 and / or the second control unit 220 can control the fan to start working according to the position information fed back by the detection device; when the movable panel 200 is in the folded position, the first control unit 210 and / or the second control unit 220 can control the fan to stop working according to the position information fed back by the detection device.

[0061] In the above structure, the position of the movable plate 200 is detected by the detection device, so that when the movable plate 200 rotates to the unfolded position, the first control unit 210 and / or the second control unit 220 can control the fan to automatically turn on, and the range hood starts to absorb oil fumes. During the use of the range hood, the user can also manually control the speed of the fan or directly turn off the fan through the second control unit 220. When the movable plate 200 rotates to the folded position, the first control unit 210 and / or the second control unit 220 can control the fan to automatically turn off, so that the range hood stops working in time, thereby making the use of the range hood more intelligent and convenient for users.

[0062] It can be understood that in the above structure, the first control unit 210 and the second control unit 220 can specifically be two independent controllers, both of which can control the operation of the fan, or the first control unit 210 and the second control unit 220 can also be just command input devices for users to input commands, such as touch screen keys or buttons. In this case, the control mechanism also includes a control module electrically connected to the first control unit 210 and the second control unit 220. The control module can control the operation of the fan or the actuator according to the commands input by the first control unit 210 and the second control unit 220.

[0063] Reference Figures 1 to 9 In some embodiments, the front wall of the casing 100 includes a first inclined portion 140 and a second inclined portion 150, the first inclined portion 140 is arranged to be inclined backward from top to bottom, and the second inclined portion 150 is connected to the lower end of the first inclined portion 140 and is arranged to be inclined forward from top to bottom; the top smoke inlet 120 is opened in the first inclined portion 140, and the side smoke inlet 130 is opened in the second inclined portion 150.

[0064] In the above structure, the first inclined portion 140 is arranged above the second inclined portion 150, and the first inclined portion 140 is arranged to tilt backward from top to bottom, and the top smoke inlet 120 is opened on the first inclined portion 140, so that the oil smoke flowing upward can enter the smoke collecting chamber 110 from the top smoke inlet 120, and by arranging the second inclined portion 150 to tilt forward from top to bottom, the lower end of the second inclined portion 150 can be extended close to the stove, and the side smoke inlet 130 is opened on the second inclined portion 150, so that the oil smoke close to the stove can flow directly into the smoke collecting chamber 110 through the side smoke inlet 130. It can be seen that the arrangement of the first inclined portion 140 and the second inclined portion 150 can quickly guide the oil smoke into the smoke collecting chamber 110, which is conducive to greatly improving the smoking efficiency, facilitating the user's use, and improving the user's experience.

[0065] Reference Figures 1 to 4 In some embodiments, a smoke collecting cavity 160 recessed backward is provided on the front wall of the casing 100, and the first inclined portion 140 and the second inclined portion 150 are both provided on the rear inner wall of the smoke collecting area; when the movable plate 200 is in the folded position, the movable plate 200 is arranged in the up and down direction and is close to or attached to the periphery of the smoke collecting cavity 160.

[0066] In the above structure, the setting of the smoke collecting chamber 160 can achieve a better smoke collecting effect, conveniently guide the oil smoke to flow to the top smoke inlet 120 and the side smoke inlet 130, prevent the oil smoke from overflowing, and greatly improve the oil smoke extraction effect of the range hood. In addition, when the movable plate 200 is in the folded position, the movable plate 200 is arranged in the up and down direction and is close to or attached to the periphery of the smoke collecting chamber 160, thereby not only closing the smoke collecting chamber 160, thereby preventing the odor generated by the grease and oil smoke accumulated in the smoke collecting chamber 110 from leaking out of the smoke collecting chamber 160, but also preventing mosquitoes from entering the smoke collecting chamber 110, and at the same time, it can also reduce the size of the housing 100 in the front and rear directions, that is, make the housing 100 smaller in size, not only convenient for transportation, but also convenient for hiding the range hood inside the cabinet.

[0067] Reference Figures 6 to 9 In some embodiments, when the movable panel 200 is in the folded position, the movable panel 200 is arranged to tilt backward from top to bottom, and the rear side surface of the movable panel 200 is adjacent to the first inclined portion 140 , and the lower side surface of the movable panel 200 is adjacent to the second inclined portion 150 .

[0068] In the above structure, when the range hood is not in use, the movable plate 200 is in a folded position and tilted backward from top to bottom. At this time, the rear surface of the movable plate 200 is adjacent to the first inclined portion 140, thereby more effectively preventing the odor generated by the grease and oil smoke accumulated in the smoke collecting chamber 110 from seeping out from the top smoke inlet 120, and also preventing mosquitoes from entering the smoke collecting chamber 110 through the top smoke inlet 120. Moreover, since the movable plate 200 is not in contact with the first inclined portion 140, it is also possible to prevent the oil stains on the oil net at the smoke inlet from contaminating the movable plate 200. In addition, the lower surface of the movable plate 200 is adjacent to the second inclined portion 150, which can more effectively prevent the odor generated by the grease and oil smoke accumulated in the smoke collecting chamber 110 from seeping out from the side smoke inlet 130, and can also prevent mosquitoes from entering the smoke collecting chamber 110 through the side smoke inlet 130. Moreover, since the movable plate 200 is not in contact with the first inclined portion 140, it can also prevent the oil stains on the oil net at the smoke inlet from polluting the movable plate 200.
