Detailed Description
To clearly illustrate the design concept of the present invention, the following description is made with reference to the examples.
In order to make the technical solutions of the present invention better understood by those skilled in the art, the technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the drawings in the examples of the present invention, and it is obvious that the described examples are only a part of examples of the present invention, and not all examples. Based on the middle examples of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
In the description of the present embodiment, the terms "upper", "lower", "front", "rear", "left", "right", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
This example provides a lampblack absorber with prevent running cigarette structure, and this lampblack absorber includes: the air suction device comprises a shell, an air outlet, an air suction opening, a closed channel, a channel interface communicated with the air outlet, and an air suction opening arranged on the shell where the air suction opening is located, wherein one end of the closed channel is communicated with the channel interface, and the other end of the closed channel is connected with the air suction opening.
The lampblack absorber of this example, through the setting of airtight passageway, its one end is connected with the air exit through the passageway interface, the other end is connected with the suction opening that sets up on inlet scoop place lampblack absorber shell, when the lampblack absorber used, when discharging oil smoke outside the organism through the air exit, air exit department has high-speed highly compressed air current to pass through, can produce at passageway interface and draw the flow, under the effect of drawing, the pressure in the cavity of airtight passageway drops to below the atmospheric pressure, and then makes the lampblack around the lampblack absorber to be sucked away by the suction opening. The main body and the fan system mechanism of the existing range hood do not need to be changed, oil smoke around the range hood can be absorbed more through the air suction opening, the oil smoke absorption efficiency is improved, and the oil smoke absorption effect is improved.
The closed channel in the example adopts various shapes, and the purpose of absorbing oil smoke around the range hood from the air suction opening can be realized as long as the sealing performance of the side wall of the channel is ensured.
The present example is illustrated with a vertical range hood, but it is foreseen that the structure of the present example solution can also be applied to a side-draft range hood, with the same technical effect.
Example 1
As shown in fig. 1 to 4, in the vertical range hood in the embodiment, the housing 1 includes a fan housing 11 for mounting a fan and an impeller 3, and a smoke collecting hood housing 12 connected below the fan housing 11, a filter screen 2 is mounted on an exhaust inlet of the range hood, and the closed channel 5 is disposed on the housing 1 of the range hood.
The shell 1 of the range hood is provided with three closed channels 5, namely three side surfaces (except the side surface contacted with a wall body) of the range hood are respectively provided with one closed channel 5, so that the space on the side surface of the range hood can be fully utilized. Correspondingly, three channel interfaces 7 are arranged at an exhaust outlet 6 of the range hood, each channel interface 7 is communicated with the closed channel 5 arranged on the corresponding side surface, and a suction opening 4 connected with the other end of the closed channel 5 is arranged at the circumferential edge of the range hood around the suction opening, as shown in fig. 4, the three suction openings 4 are respectively arranged close to three edges (edges contacted with a wall body are removed) of the smoke collecting hood shell 12, so that the range covered by the range hood can effectively absorb the oil smoke nearby the range hood.
In this embodiment, the closed passage 5 includes an upper closed passage 51 provided on the blower housing 11 and a lower closed passage 52 provided on the fume collecting hood housing 12, the upper closed passage 51 is communicated with the lower closed passage 52, the radial cross section of the upper closed passage 51 is the same as the shape and size of the passage interface 7, and the radial cross section of the lower closed passage 52 from the connection end with the upper closed passage 51 to the suction opening 4 is gradually increased; moreover, the shape of the suction opening 4 is rectangular, which facilitates the processing of the suction opening 4 and the arrangement of the shape and structure of the closed channel 5.
Example 2
The present embodiment is an improvement on the basis of the embodiment, and is different from embodiment 1 in that the area of the suction opening is larger than the area of the passage interface, and the closed passage may be configured such that the size of the radial cross section from the passage interface to the suction opening is gradually increased. In addition, the range hood with the anti-smoke-leakage structure in the embodiment further comprises a smoke exhaust pipe, the smoke exhaust pipe comprises a first pipe section and a second pipe section which are connected with each other, the first pipe section is a conical pipe section, the connecting end of the first pipe section is connected with the air outlet, the diameter of the connecting end of the first pipe section is smaller than or equal to the diameter of the air outlet and is the maximum diameter position of the smoke exhaust pipe, and the connecting end of the second pipe section is connected with the common flue interface.
Through setting up the pipe of discharging fume including the toper pipeline section, when the oil smoke flows through the pipe of discharging fume, can take place venturi effect, the velocity of flow increase of oil smoke. The cavity of the closed channel is enabled to generate larger negative pressure, so that the oil smoke around the range hood is easier to be sucked away by the air suction opening.
It is noted that some of the structures may be selected differently than the specific examples given above. For example, the closed channel can also be arranged inside the range hood, so that the range hood has better integrity; the number of the closed channels can be one, two or more, the closed channels need to be arranged according to specific use requirements, and correspondingly, the channel interfaces and the air suction openings are consistent with the number of the closed channels; a closed channel can be arranged on one side close to the wall, but due to the shielding of the wall, the oil smoke on the side is less, and if the closed channel is arranged on the outer side of the shell, the range hood is inconvenient to mount on the wall; and the like, which can be made by those skilled in the art based on their basic skills based on an understanding of the inventive concept, and are not to be taken as an example herein.
Finally, it is to be understood that the above embodiments are merely exemplary embodiments that have been employed to illustrate the principles of the present invention, and that the present invention is not limited thereto. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention, and these changes and modifications are to be considered as the protection scope of the invention.
