Description

Technical Field

[0001] The utility model belongs to the technical field of range hoods, and particularly relates to a range hood and a range hood extraction system. Background Art

[0002] Existing range hoods are generally provided with different gears to adjust the suction effect of the range hood. For example, the range hood can absorb oil smoke faster at the highest gear. However, the suction effect of the range hood at the highest gear is already the performance limit. If the fan specifications remain unchanged, the suction effect cannot be further improved. Therefore, it cannot cope with certain occasions with heavier oil smoke, resulting in a narrow application range and low overall applicability.

[0003] Therefore, the existing technology needs to be improved and developed. Utility Model Content

[0004] The purpose of the utility model is to provide a range hood and a range hood extraction system, by setting the area of ​​the air inlet to be adjustable, thereby changing the pressure of the air inlet, further improving the suction effect of the range hood, effectively increasing its scope of application, and making the overall applicability higher.

[0005] In a first aspect, the utility model provides a range hood, comprising a main unit provided with an air inlet, the main unit being used to absorb oil smoke through the air inlet, the air inlet being provided with two groups of movable door panels opening and closing oppositely, the two groups of movable door panels being used to change the open area of ​​the air inlet by opening and closing.

[0006] The range hood provided by the utility model utilizes two sets of movable door panels that open and close oppositely to change the pressure of the air inlet, thereby adjusting the pressure difference between the air outlet and the air inlet, thereby further improving the suction effect of the range hood and effectively widening its application range.

[0007] Further, each set of the movable door panels includes a first door panel and a second door panel, the first door panel is slidably disposed on the mainframe and can reciprocate in a horizontal direction, the first door panel is hinged to one end of the second door panel, and the other end of the second door panel is slidably disposed on the mainframe and can reciprocate in a vertical direction;

[0008] The first door panel is used to pull the second door panel to swing to be parallel to the horizontal plane to close the air inlet, or to push the second door panel to swing to form an angle with the horizontal plane to open the air inlet.

[0009] The second door panel is equivalent to being hidden inside the main unit and providing more movable space for the first door panel, thereby making the open area of ​​the air inlet larger, thereby increasing the adjustable range of the suction effect.

[0010] Furthermore, each group of the movable door panels is provided with a sliding part and a folding part, the sliding part is slidably arranged on the main unit and can reciprocate in the horizontal direction, and the folding part is used to flatten with the movement of the sliding part to close the air inlet, or fold and shrink to open the air inlet.

[0011] The telescopic stroke of the folding portion is relatively large, so the open area of ​​the air inlet can be further increased, thereby further improving the adjustable range of the suction effect.

[0012] Furthermore, each group of the movable door panels includes a plurality of third door panels, the plurality of the third door panels are arranged in layers, adjacent third door panels are slidably connected and can slide relative to each other in a horizontal direction; the plurality of the third door panels are used to close the air inlet by moving away from each other, or to open the air inlet by stacking each other.

[0013] Compared with the above-mentioned folding portion, the stacked third door panel structure is simpler and easier to clean and maintain, and is also more reliable.

[0014] Furthermore, each group of the movable door panels includes a rolling tube and a rolling curtain, the first end of the rolling curtain is fixedly connected to the rolling tube and the second end is slidably arranged on the main unit, and the rolling curtain is used to extend from the rolling tube to close the air inlet, or to be wound around the rolling tube to open the air inlet.

[0015] Furthermore, a latch is provided at the second end of the rolling blind, and a plurality of spaced-apart sockets are provided on the host, and the latch is used to be plugged into any of the sockets to fix the position of the rolling blind.

[0016] In a second aspect, the utility model provides a range hood extraction system, comprising the range hood and fan mentioned above, wherein the main unit of the range hood is also provided with an air outlet, the main unit is connected to the fan through a pipeline and is used to discharge the oil fume through the air outlet via the pipeline.

[0017] Furthermore, it also includes an indoor space and an outdoor space, the range hood is located in the indoor space, and the fan is located in the outdoor space.

[0018] Furthermore, it includes an indoor space and an outdoor space, the indoor space includes a ceiling area, the outdoor space includes a common flue, the main unit is connected to the common flue through the pipe, and the fan is located in the ceiling area and is used to draw oil smoke from the indoor space into the common flue.

[0019] Furthermore, the fan is a hair dryer and is used to spray airflow along the extension direction of the pipeline.

[0020] From the above, it can be seen that when the range hood of the utility model is in the highest gear, the user can also change the open area of ​​the air inlet by controlling the opening and closing size of the two sets of movable door panels, thereby changing the air inlet pressure and further improving the suction effect of the range hood. Under the same fan specifications, the range hood can meet more usage occasions, greatly broaden its scope of application, and effectively improve its overall applicability.

[0039] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0040] Reference Figure 1 The utility model provides a range hood, including a host 100 provided with an air inlet, the host 100 is used to absorb oil smoke through the air inlet, the air inlet is provided with two sets of movable door panels 200 that open and close oppositely, and the two sets of movable door panels 200 are used to change the open area of ​​the air inlet by opening and closing.

[0041] In actual application, the range hood absorbs oil smoke generally by using the fan to generate air pressure difference, thereby driving the oil smoke to be discharged outdoors. When the specifications of the fan are determined, the suction effect that can be achieved by the highest gear of the range hood is its performance limit, and the suction effect cannot be further improved. Therefore, it cannot be used in occasions with heavier oil smoke. However, this embodiment changes the open area of ​​the air inlet by actively controlling the opening and closing size of the movable door panels 200 by providing two sets of movable door panels 200 that open and close in opposite directions, thereby changing the pressure of the air inlet without changing the specifications of the fan, so that a larger pressure difference is formed between the air inlet and the air outlet, thereby achieving the effect of regulating the suction effect, for example, by reducing the open area of ​​the air inlet, the smoke exhaust capacity of the range hood is improved, so that the oil smoke is discharged to the outdoors faster and more efficiently.

[0042] Compared with traditional range hoods, the range hood of this embodiment can further improve its suction effect by controlling the open area of ​​the air inlet when it is in the highest gear, making it suitable for occasions with heavier oil smoke. This will undoubtedly broaden the scope of application of the range hood and improve product performance and user experience.

[0043] In certain embodiments, referring to Figure 2 and attached Figure 3 Each set of movable door panels 200 includes a first door panel 211 and a second door panel 212. The first door panel 211 is slidably disposed on the host 100 and can reciprocate in the horizontal direction. The first door panel 211 is hinged to one end of the second door panel 212. The other end of the second door panel 212 is slidably disposed on the host 100 and can reciprocate in the vertical direction.

[0044] The first door panel 211 is used to pull the second door panel 212 to swing to be parallel to the horizontal plane to close the air inlet, or to push the second door panel 212 to swing to form an angle with the horizontal plane to open the air inlet.

[0045] In this embodiment, when the first door panel 211 gradually opens the air inlet, the second door panel 212 will be pushed by the first door panel 211 and swing toward the inside of the host 100 at an angle. At this time, the second door panel 212 is equivalent to being hidden inside the host 100 and providing more movable space for the first door panel 211, thereby making the open area of ​​the air inlet larger, thereby improving the adjustable range of the suction effect.

[0046] On the contrary, when the first door panel 211 gradually closes the air inlet, the second door panel 212 will be pulled by the first door panel 211 until it is completely horizontal, thereby cooperating with the first door panel 211 to close the air inlet.

[0047] It should be noted that the sliding setting in the present invention can be achieved by, for example, setting a slide rail, but is not limited to this. The specific structure for achieving sliding belongs to the prior art and will not be described in detail here.

[0048] In certain embodiments, referring to Figure 4 Each set of movable door panels 200 is provided with a sliding portion 221 and a folding portion 222. The sliding portion 221 is slidably arranged on the host 100 and can reciprocate in the horizontal direction. The folding portion 222 is used to flatten with the movement of the sliding portion 221 to close the air inlet, or fold and shrink to open the air inlet.

[0049] In this embodiment, when the sliding part 221 gradually opens the air inlet, the folding part 222 will be pressed by the sliding part 221 and folded, and when the sliding part 221 gradually closes the air inlet, the folding part 222 will be pulled by the sliding part 221 and unfolded, thereby cooperating with the sliding part 221 to close the air inlet.

[0050] In this embodiment, the telescopic stroke of the folding portion 222 is relatively large, so the open area of ​​the air inlet can be further increased, thereby further improving the adjustable range of the suction effect.

[0051] In certain embodiments, referring to Figure 5 and attached Figure 6 Each set of movable door panels 200 includes a plurality of third door panels 231, and the plurality of third door panels 231 are arranged in layers. Adjacent third door panels 231 are slidably connected and can slide relative to each other in a horizontal direction; the plurality of third door panels 231 are used to close the air inlet by moving away from each other, or to open the air inlet by stacking each other.

[0052] In this embodiment, a plurality of third door panels 231 are arranged in a stacked form to achieve an effect similar to that of folding, thereby controlling the open area of ​​the air inlet. Compared with the folding portion 222 of the above-mentioned embodiment, the stacked third door panels 231 have a simpler structure and are easier to clean and maintain, and are also more reliable.

[0053] Specifically, for example, each group of movable door panels 200 includes three third door panels 231, and the three third door panels 231 are respectively the fourth door panel, the fifth door panel and the sixth door panel. The fourth door panel is fixedly arranged on the host and is slidably connected to the fifth door panel, the fifth door panel is slidably connected to the sixth door panel, and the sixth door panel is slidably arranged on the host.

[0054] In certain embodiments, referring to Figure 7 and attached Fig. 9 Each set of movable door panels 200 includes a roller tube 241 and a roller curtain 242. The first end of the roller curtain 242 is fixedly connected to the roller tube 241 and the second end is slidably set on the host 100. The roller curtain 242 is used to extend from the roller tube 241 to close the air inlet, or to be wound on the roller tube 241 to open the air inlet.

[0055] In this embodiment, in actual application, the roller blind 242 can be completely rolled up into the roller tube 241. After rolling up, the overall volume is smaller so that the air inlet can obtain a larger open area, thereby allowing the suction effect of the range hood to obtain a wider adjustable range.

[0056] For further information, see Attachment Figure 7 and attached Figure 8 A latch 243 is provided at the second end of the rolling curtain 242 , and a plurality of spaced-apart sockets 110 are provided on the host 100 . The latch 243 is used to be plugged into any socket 110 to fix the position of the rolling curtain 242 .

[0057] The roller blind 242 is fixed at any position of the main unit 100 by using the latch 243 and the socket 110, so as to facilitate user operation. At the same time, the sockets 110 at different positions correspond to different open areas of the air inlet, so the user can more conveniently adjust the suction effect of the range hood according to the position of the socket 110.

[0058] Reference Fig.10 The utility model provides a range hood extraction system, including the range hood and the fan 300 in the above embodiment. The host 100 of the range hood is also provided with an air outlet. The host 100 is connected to the fan 300 through a pipeline and is used to discharge the oil smoke through the air outlet through the pipeline.

[0059] In certain embodiments, referring to Fig.10 The range hood system also includes an indoor space 410 and an outdoor space 420. The range hood is located in the indoor space 410, and the fan 300 is located in the outdoor space 420. Placing the fan 300 in the outdoor space 420 can prevent the noise generated by the operation of the fan 300 from propagating in the indoor space 410, which helps to achieve a noise reduction effect in the indoor space 410.

[0060] In certain embodiments, referring to Fig.11 The range fumes extraction system further includes an indoor space 410 and an outdoor space 420, wherein the indoor space 410 includes a ceiling area 411, and the outdoor space 420 includes a common flue 421, the host 100 is connected to the common flue 421 through a pipe, and the fan 300 is located in the ceiling area 411 and is used to draw the fumes from the indoor space 410 into the common flue 421.

[0061] In this embodiment, for a building with a ceiling area 411 and a public flue 421, since the fan 300 is generally not suitable for installation in the public flue 421, the fan 300 is set in the ceiling area 411 to be as far away from the main unit 100 as possible, which can also prevent the noise generated by the fan 300 from being perceived by the user, and is also conducive to achieving the effect of indoor noise reduction.

[0062] In the prior art, most range hoods are used in conjunction with an exhaust fan to enable the range hood to achieve the basic function of extracting oil smoke. However, since the oil smoke is directly sucked into the exhaust fan, the exhaust fan is often covered with oil stains, thereby reducing its service life.

[0063] In some preferred embodiments, the fan 300 is a hair dryer and is used to spray airflow along the extension direction of the pipeline.

[0064] In this embodiment, the airflow ejected by the hair dryer can also induce the air flow in the pipe (jet principle, which is common knowledge and will not be elaborated here), thereby enabling the range hood to achieve the basic function of extracting oil fumes. However, compared with the exhaust fan, the oil fumes will not be sucked into the hair dryer, so it can avoid oil stains from adhering to the hair dryer, making the hair dryer have a longer service life.

[0065] In the description of this specification, the description with reference to the terms "one embodiment", "certain embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiments or examples are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0066] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
