[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] Reference Figures 1 to 4 , which is an embedded range hood according to an embodiment of the present invention, comprises a base 100, a fan assembly 200 and a filter 300. The base 100 comprises a smoke hood 110 and a bellows body 120. The bellows body 120 is arranged on the upper side of the smoke hood 110. The smoke hood 110 is provided with a smoke collecting chamber 111 and an air inlet 112 communicating with the smoke collecting chamber 111. The bellows body 120 is provided with a bellows chamber 121 and an air outlet 122 communicating with the bellows chamber 121. The bellows chamber 121 is communicated with the smoke collecting chamber 111. The fan assembly 200 is arranged in the bellows body 120 and is used to form an airflow from the air inlet 112 to the air outlet 122. The filter 300 is arranged in the smoke hood 110 and covers the air inlet 112. The bellows body 120 is arranged on the smoke hood 110 so as to be adjustable in the horizontal direction.

[0032] When installing a built-in range hood, the horizontal position of the bellows body 120 relative to the smoke hood 110 can be adjusted to adapt to the internal space layout of the cabinet, so that the built-in range hood can be adapted to be installed in cabinets with different internal space layouts, thereby facilitating the installation of the built-in range hood.

[0033] Specifically, the fan assembly 200 includes a volute, a centrifugal fan wheel, and a motor. The motor drives the centrifugal fan wheel to rotate, and the motor and the centrifugal fan wheel are located within the volute. It is conceivable that the fan assembly 200 can also include an axial flow fan wheel and a motor. The motor drives the axial flow fan wheel to rotate to blow the air in the bellows cavity 121 out through the air outlet 122.

[0034] In an embodiment, the base 100 further includes a pressing plate 130 and a threaded fastener. The pressing plate 130 is provided with a threaded hole, the smoke hood 110 is provided with a clearance hole, and the air box body 120 is provided with a strip through hole 123. The threaded fastener is passed through the clearance hole and the strip through hole 123. The threaded fastener is threadedly connected to the pressing plate 130, so that the pressing plate 130 and the smoke hood 110 clamp the air box body 120. When the threaded fastener is tightened, the position of the air box body 120 is clamped and fixed by the pressing plate 130 and the smoke hood 110. When the position of the air box body 120 needs to be adjusted, the threaded fastener can be loosened. At this time, the threaded fastener can move relative to the strip through hole 123, thereby allowing the air box body 120 to move horizontally relative to the smoke hood 110. Then, the threaded fastener is re-tightened to complete the position adjustment of the air box body 120. The position adjustment structure is simple and the installation and fixation are relatively firm.

[0035] Specifically, the threaded fastener is a screw.

[0036] It is conceivable that in other embodiments, the relative position adjustment of the air box body 120 and the smoke hood 110 can be achieved through other structures. For example, a strip through hole 123 is provided in the smoke hood 110, and a clearance through hole is provided in the air box body 120. A bolt and nut pair is passed through the clearance through hole and the strip through hole 123. When the bolt and nut pair is tightened, the position of the air box body 120 relative to the smoke hood 110 can be fixed; when the bolt and nut pair is loosened, the bolt and nut pair can be allowed to slide along the strip through hole 123 to adjust the position of the air box body 120; or the air box body 120 can be slidably connected to the smoke hood 110 through a slide rail and groove structure, and a threaded through hole is provided in the air box body 120. A screw is threadedly connected to the threaded through hole, and one end of the screw abuts against the smoke hood 110. When the screw is tightened, the position of the air box body 120 relative to the smoke hood 110 is restricted. When the screw is loosened, the air box body 120 is allowed to slide, thereby completing the function of adjusting the position of the air box body 120.

[0037] In the embodiment, the strip-shaped through hole 123 is extended in the front-to-back direction, so that the position of the wind box body 120 can be adjusted front-to-back relative to the smoke collecting hood 110 , which has a simple structure and is easy to implement.

[0038] It is conceivable that, in other embodiments, the strip-shaped through hole 123 may also be arranged to extend in the left-right direction, so that the position of the wind box can be adjusted left-right relative to the smoke collecting hood 110 .

[0039] In this embodiment, a communication hole 113 is formed on the upper side of the smoke hood 110, and the bellows cavity 121 communicates with the smoke collection cavity 111 through the communication hole 113. The lower side of the plate of the bellows body 120 is arranged around the communication hole 113, and a pressure plate 130 is arranged around the opening of the communication hole 113. The pressure plate 130 is arranged around the opening of the communication hole 113, which facilitates fixing the lower side of the plate of the bellows body 120 to the opening of the communication hole 113, thereby making the bellows body 120 more compact.

[0040] Specifically, the communicating hole 113 is a square hole, the bellows body 120 is a rectangular box, the lower side of the bellows body 120 is open, and the lower side of the bellows body 120 surrounds the periphery of the opening of the communicating hole 113 .

[0041] In the embodiment, the smoke hood 110 is provided with a reinforcing rib 140 around the opening of the communication hole 113. The provision of the reinforcing rib 140 increases the structural strength of the smoke hood 110 around the opening of the communication hole 113, facilitates supporting and fixing the wind box body 120 on the upper side, and avoids the risk of deformation of the smoke hood 110.

[0042] In this embodiment, the filter 300 is tilted, and the base 100 is provided with an oil receiving cup 150, which is located below the lowermost end of the filter 300. The filter 300 can condense the oil smoke, causing the oil smoke to condense into oil droplets that adhere to the filter 300. Therefore, the tilted filter 300 allows the oil droplets to move toward the lowermost side of the filter 300 under the action of gravity, and drip through the lowermost end of the filter 300 to the oil receiving cup 150 for collection. This avoids the risk of excessive oil droplets on the filter 300 dripping randomly, facilitates the cleaning of the filter 300, and improves cooking hygiene.

[0043] Specifically, the filter 300 is a hollow metal mesh. Air can pass through the filter 300 through the hollow holes. When high-temperature oil smoke contacts the low-temperature filter 300, it condenses and adheres to the filter 300. It is conceivable that in other embodiments, the filter 300 can also be other types of filter 300, and those skilled in the art can configure it according to actual needs.

[0044] In an embodiment, air outlet holes are provided on the upper side of the bellows body 120 in the up and down directions, and the air outlet holes form an air outlet 122; the base 100 also includes a check plate 160, one side of the check plate 160 is pivotally connected to the hole wall of the air outlet, and the hole wall of the air outlet is provided with a supporting portion 124 for supporting the other side of the check plate 160, and the check plate 160 has an open state and a closed state. In the open state, the other side of the check plate 160 is flipped upward to open the air outlet; in the closed state, the supporting portion 124 supports the other side of the check plate 160, and the check plate 160 closes the air outlet. When the fan assembly 200 is not started, the anti-return plate 160 is in a closed state under the action of gravity, and the other side of the anti-return plate 160 rests on the supporting portion 124 to close the air outlet to prevent outside air and rainwater from flowing back. When the fan assembly 200 is started, the smoke is discharged upward through the air outlet. At this time, under the push of the wind flow, the other side of the anti-return plate 160 flips upward, opening the air outlet, thereby allowing the smoke to be discharged normally.

[0045] Specifically, two anti-return plates 160 are provided, and both anti-return plates 160 are semicircular, and the two anti-return plates 160 cooperate to close or open the circular air outlet. It is conceivable that when the air outlet is a square hole, a square anti-return plate 160 can also be used to complete the opening and closing of the air outlet.

[0046] In the embodiment, a light emitting assembly 400 is provided on the lower side of the smoke hood 110, with the light emitting side of the light emitting assembly 400 facing downward. When the range hood is started, the light emitting assembly 400 can be illuminated to illuminate the cooking area below and improve the brightness of the cooking area.

[0047] Specifically, the light emitting component 400 may be an RGB lamp, or a light strip, a light board or other structures, as long as it can emit light.

[0048] Specifically, the electric control box 500 is further included and is disposed outside the bellows body 120 and above the bellows body 120. By disposing the electric control box 500 outside the bellows body 120, the built-in range hood is concealed after installation, preventing accidental contact. Furthermore, since the electric control box 500 is not within the bellows cavity 121, the risk of contamination of the electric control box 500 by oil smoke and dirt after prolonged use of the built-in range hood is avoided.

[0049] In this embodiment, the upper side of the bellows body 120 is provided with air outlets in the vertical direction, forming an air outlet 122. The base 100 also includes a protective plate 170, which is vertically adjustable and disposed on the bellows body 120. The protective plate 170 is disposed around the outer periphery of the air outlet. After the built-in range hood is installed in the cabinet, the air outlet is connected to the outside world through the air outlet duct. The vertical position of the protective plate 170 can then be adjusted based on the remaining installation space above the bellows body 120, so that the protective plate 170 can conceal and block the air outlet and the air outlet duct. This not only makes the built-in range hood look neater, but also provides a certain degree of protection for the air outlet and the air outlet duct.

[0050] Specifically, the protective plate 170 is provided with vertically extending slots, through which screws are inserted to lock the protective plate 170 to the bellows body 120. When the screws are loosened, the position of the protective plate 170 can be adjusted up and down. It is conceivable that the protective plate 170 can also be provided with a row of vertical pin holes, and the bellows body 120 can also be provided with pin holes, with pins inserted into the pin holes of both to achieve vertical adjustment.

[0051] Specifically, the electric control box 500 is located on the upper side of the air box body 120 and beside the air outlet. At this time, the protective plate 170 also has a certain protective effect on the electric control box 500.
