[0002] During the cooking process in the kitchen, the range hood plays an important role. Its powerful suction can effectively discharge the fumes generated during the cooking process, thereby greatly improving the air quality in the kitchen and protecting the health of users.

[0003] In the prior art, a range hood comprises a casing and a fan arranged in the casing. The casing comprises a casing and a side panel arranged on the side of the casing. A suction port is opened on the side of the casing facing the cooking device. The side panel and the casing enclose a cavity for the oil smoke to flow to the fan.

[0004] However, when the range hood is in operation, the noise generated by the fan will be directly transmitted into the interior of the casing. When the noise comes into contact with the side panel, it is easy to form reflection and echo in the cavity inside the casing, resulting in loud noise coming out of the casing and a poor user experience.

[0037] The utility model discloses a shell device and a range hood.

[0038] Reference Figures 1 to 3 The housing device includes a housing 1 and a noise reduction layer 3. A side panel assembly 2 is provided on the side of the housing 1. The housing 1 has a smoke extraction port for extracting oil smoke. The housing 1 and the side panel assembly 2 enclose a guide cavity connected to the smoke extraction port. The noise reduction layer 3 is located on a side of the side panel assembly 2 close to the guide cavity.

[0039] Specifically, the casing 1 is in the shape of a long strip, and a fan cover 4 is arranged on the top side thereof, and a fan module is built in the fan cover 4. A smoke exhaust port connected to the fan cover 4 is opened on the top wall of the casing 1, and the lower side of the casing 1 is arranged obliquely, and a smoke extraction port is opened on this side. The oblique arrangement makes it unnecessary for the casing 1 as a whole to be arranged directly opposite the stove, but can be biased to one side of the stove to avoid collision between the user and the casing 1. The casing 1 can be formed by enclosing a plurality of plate-like structures, and a side panel assembly 2 can be respectively arranged on both sides of the length direction of the casing 1 to form a closed guide cavity inside the casing 1.

[0040] A noise reduction layer 3 is arranged on one side of the side panel assembly 2 close to the guide cavity, and the noise reduction layer 3 can fill the entire inside of the side panel assembly 2, or can be arranged outside the side panel assembly 2. The noise reduction layer 3 can be made of microporous sound-absorbing cotton, or can be made of other materials that meet the requirements.

[0041] When the fan module is running to extract the oil smoke, the gas will flow toward the fan module through the guide cavity formed by the side panel assembly 2 and the housing 1, so as to form a local negative pressure at the smoke extraction port, and the oil smoke will gradually enter the guide cavity through the smoke extraction port, and then flow along the guide cavity to the fan module and be discharged from the kitchen. During the use of the shell device, when the noise generated by the operation of the fan module enters the housing 1, the noise reduction layer 3 can buffer the noise, effectively suppressing the reflection and reverberation of the noise inside the housing 1, thereby reducing the noise intensity transmitted from the housing 1 and improving the user experience.

[0042] Reference Figure 3 and Figure 4 Optionally, the side panel assembly 2 includes a first side panel 23 and a second side panel 24. A plurality of second side panels 24 connected to the housing 1 are arranged around the edge of the first side panel 23, and the noise reduction layer 3 is arranged in a space enclosed by the first side panel 23 and the second side panel 24.

[0043] Specifically, the first side panel 23 may be in the shape of a right-angled trapezoid, and a second side panel 24 is disposed on each of its four sides, and the second side panel 24 is along the thickness direction of the first side panel 23. It should be understood that the first side panel 23 may also be in other shapes, as long as it can be adapted to the shape of the housing 1, and the present invention does not limit this. The annular second side panel 24 forms a space inside the side panel assembly 2 that can accommodate the noise reduction layer 3, and also allows the side panel assembly 2 to maintain a certain thickness as a whole, which is conducive to improving the overall structural strength of the side panel assembly 2.

[0044] Optionally, a third side plate 25 opposite to the first side plate 23 is provided on a side of any second side plate 24 away from the first side plate 23 , and a cavity 21 is formed among the first side plate 23 , the second side plate 24 and the third side plate 25 .

[0045] Specifically, a third side panel 25 is provided on the second side panel 24 of the hypotenuse of the first side panel 23, and the third side panel 25 is opposite to the first side panel 23, and a cavity 21 is formed between the third side panel 25 and the first side panel 23. The height of the third side panel 25 can be less than half of the first side panel 23, so as to form a cavity 21 at a local position on the lower side of the side panel assembly 2, thereby reducing the material and reducing the cost while ensuring that the overall structural strength and noise reduction performance of the side panel assembly 2 meet the requirements. The first side panel 23, the second side panel 24 and the third side panel 25 can be spliced ​​to enclose and form the side panel assembly 2, and adjacent structures can be fixedly connected by welding or the like.

[0046] Optionally, the first side plate 23, the second side plate 24 and the third side plate 25 are of an integrated structure.

[0047] Specifically, in order to improve the overall aesthetics of the side panel assembly 2, the side panel assembly 2 is an integrated structure, that is, the first side panel 23, the second side panel 24 and the third side panel 25 are all formed by a sheet metal bending process, so that there will be no welds on the surface of the side panel assembly 2 as a whole, and no fasteners such as screws are required, which is conducive to improving the overall aesthetics of the side panel assembly 2. In addition, the side panel assembly 2 formed by the integrated structure has good structural strength and can meet the overall strength requirements of the housing 1. The side of the second side panel 24 away from the first side panel 23 can be further bent to form a splicing plate 26, which can be adapted to the housing 1, so that the possibility of gaps in the splicing between the side panel assembly 2 and the housing 1 is reduced, further improving the overall aesthetics of the housing 1.

[0048] Optionally, the noise reduction layer 3 is at least partially filled in the cavity 21 , and the third side plate 25 has a plurality of first sound transmission holes.

[0049] Specifically, in order to save costs, the cavity 21 is formed only at a local position of the side panel assembly 2, and the noise reduction layer 3 can be partially filled in the cavity 21, while the rest can be directly exposed outside the cavity 21. The exposed part can be provided with a shielding structure to separate the noise reduction layer 3 from the waste oil in the diversion cavity, and enable the noise to be transmitted to the noise reduction layer 3. In other embodiments, the noise reduction layer 3 can also be filled in the cavity 21 as a whole. A plurality of first sound transmission holes are spaced apart on the third side panel 25, so that the noise can contact the noise reduction layer 3 through the first sound transmission holes. It should be understood that in other embodiments, the cavity 21 can also be formed by the entire side panel assembly 2, in which case the entire noise reduction layer 3 can be set in the cavity 21. In another embodiment, the noise reduction layer 3 can also be set as a whole on the outside of the cavity 21, that is, the side panel assembly 2 corresponds to one side of the diversion cavity, in which case the noise reduction layer 3 will occupy part of the space of the diversion cavity, thereby forming a side panel assembly 2 with a double-layer noise reduction structure of the noise reduction layer 3 and the diversion cavity. The specific position of the noise reduction layer 3 can be set according to the actual space layout and scene requirements.

[0050] Optionally, an oil-blocking net 5 is provided near the surface of the guide cavity of the noise reduction layer 3, and the oil-blocking net 5 has a plurality of second sound transmission holes.

[0051] Specifically, an oil retaining net 5 is sleeved on the surface of the noise reduction layer 3. The oil retaining net 5 has a mesh structure, which can effectively separate the noise reduction layer 3 from the waste oil contained in the oil smoke in the guide cavity, so that when the oil smoke flows in the guide cavity, the possibility of contact between the waste oil and the noise reduction layer 3 can be effectively reduced. At the same time, the oil retaining net 5 with a mesh structure itself has a large number of second sound transmission holes, so that the noise reduction layer 3 can fully contact with the noise while reducing the contact with the waste oil, so as to ensure that the noise reduction layer 3 has a good buffering effect on noise.

[0052] Optionally, multiple first sound transmission holes and multiple second sound transmission holes are staggered. Specifically, the entire surface of the noise reduction layer 3 can be covered with the oil-blocking net 5, and the noise in the cavity 21 contacts the noise reduction layer 3 through the first sound transmission holes. In order to ensure the oil-blocking effect of the noise reduction layer 3, the first sound transmission holes and the second sound transmission holes are staggered to ensure that the noise reduction layer 3 has enough area to contact the noise, and can also effectively separate the part of the noise reduction layer 3 located in the cavity 21 from the waste oil. The specific size of the first sound transmission hole and the second sound transmission hole can be designed according to the actual size of the third side panel 25, as long as the staggered distribution can be satisfied, and this application does not limit this.

[0053] Reference Figure 3 and Figure 4 Optionally, the housing device further includes an oil baffle plate 6 . The oil baffle plate 6 is disposed on the side plate assembly 2 and can close the opening of the cavity 21 , and the noise reduction layer 3 is filled in the cavity 21 .

[0054] Specifically, an oil baffle plate 6 is provided on the side of the side panel assembly 2 facing the guide cavity, and the oil baffle plate 6 and the side panel assembly 2 can be fixedly connected by fasteners such as bolts, or can be fixedly connected by welding or bonding. The oil baffle plate 6 is located at the opening of the cavity 21, and it can block the opening of the cavity 21 to close the cavity 21, thereby reducing the connection area between the cavity 21 and the guide cavity, so as to reduce the possibility of waste oil and the like entering the cavity 21, and the noise reduction layer 3 is completely placed in the cavity 21, and holes and other structures are provided on the third side panel 25, so as to facilitate direct contact between the noise and the noise reduction layer 3. It should be understood that the third side panel 25 may not have holes, and in this case, the third side panel 25 can be made of a material with a higher porosity and a better hardness. The material with a higher porosity has a better sound transmission effect, and can transmit the noise to the noise reduction layer 3 to achieve noise reduction. At the same time, the oil baffle plate 6 closes the opening of the cavity 21 and fixes the third side plate 25 and the first side plate 23 together, which can further improve the overall structural strength of the side plate assembly 2.

[0055] Optionally, the oil baffle plate 6 extends obliquely to form a flow guide slope 61 on the top wall of the oil baffle plate 6 .

[0056] Specifically, an oil box for collecting waste oil is provided on one side of the housing 1, and the oil baffle plate 6 is tilted toward the side where the oil box is provided. In this embodiment, the oil box is located at the rear side of the housing 1, and the oil baffle plate 6 can be tilted in a manner of being higher in the front and lower in the rear, so that the top wall of the oil baffle plate 6 is tilted and serves as a guide slope 61 to facilitate the recovery of waste oil.

[0057] Optionally, the oil baffle plate 6 is provided with a stop plate 62 which is in contact with the inner wall of the side plate assembly 2 .

[0058] Specifically, a stop plate 62 is provided on the side of the oil baffle plate 6 away from the guide cavity, the stop plate 62 extends along the thickness direction of the oil baffle plate 6, and the side surface of the stop plate 62 is attached to the inner wall of the side plate assembly 2. The provision of the stop plate 62 can reduce the gap between the oil baffle plate 6 and the inner wall of the side plate assembly 2, thereby improving the sealing effect of the cavity 21. A right-angled trapezoidal limiting plate 63 can also be provided on both sides of the front and rear of the stop plate 62, and the limiting plate 63 can completely block the guide slope 61 to improve the stopping effect of oil smoke.

[0059] Optionally, the oil baffle plate 6 has a closing plate 64 that fits both the outer side wall of the side plate assembly 2 and the end surface of the casing 1 .

[0060] Specifically, a closing plate 64 is provided on the side of the oil baffle plate 6 close to the guide cavity, and the closing plate 64 extends downward, and one side of the closing plate 64 is in contact with the outer wall of the third side plate 25, and the other side is in contact with the end face of the housing 1. A plurality of fixing holes are provided through the closing plate 64, and a mounting hole connected to the fixing hole is also provided on the outer wall of the side plate assembly 2. A bolt is provided as a fastener in each fixing hole and mounting hole, and the fastener can pass through the end face of the housing 1 to fix the closing plate 64, the third side plate 25 and the housing 1 together. In this way, the gap between the oil baffle plate 6 and the side plate assembly 2 is further closed, and the sealing effect of the cavity 21 is improved.

[0061] Reference Figure 5 Optionally, the side panel assembly 2 partially extends out of the housing 1 to form a smoke collecting chamber 22 outside the smoking port.

[0062] Specifically, the side panel assembly 2 is in the shape of a right-angled trapezoid as a whole, and its front and rear sides are parallel side walls, which are flush with the front and rear sides of the casing 1 respectively. The top side of the side panel assembly 2 is perpendicular to the front and rear sides and flush with the top wall of the casing 1, and the bottom side of the side panel assembly 2 is inclined. It should be understood that the side panel assembly 2 as a whole can also be in other shapes as long as it meets the structural requirements and aesthetic requirements. The overall height of the side panel assembly 2 is greater than the height of the casing 1, so that the bottom side of the side panel assembly 2 can partially extend out of the casing 1, and in order to ensure the overall aesthetics, a cavity 21 is formed on the bottom side of the side panel assembly 2, so that the part forming the cavity 21 extends out of the casing 1 to form a smoke chamber 22, thereby reducing the possibility of the inside of the side panel assembly 2 being exposed.

[0063] By forming the smoke collecting chamber 22, a smoke gathering space can be formed outside the smoke extraction port. When the fan is running, a negative pressure can be formed in the smoke collecting chamber 22 first, so that the smoke and other gases can be quickly gathered in the smoke collecting chamber 22. This not only allows the smoke and other gases to quickly enter the guide chamber through the smoke extraction port, but also can gather the smoke outside the casing 1, reducing the possibility of the smoke and other gases drifting to other spaces.

[0064] The range hood comprises: a fan module and a housing device as in the above embodiment. The fan module is arranged in the housing device.

[0065] When the range hood is in operation, the noise generated by the fan module penetrates into the shell device, and the noise reduction layer 3 in the shell device can effectively buffer the noise, thereby suppressing the reflection and reverberation of the noise, reducing the intensity of the noise transmission, and effectively improving the user experience.

[0066] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
