[0031] Combine the following Figures 1 to 10 The embodiments of the present application are described in detail.

[0032] Based on the above content, an embodiment of the present application provides a range hood. In a first aspect of the present application, a range hood is provided, which includes a body 100, a fan assembly 200, a separator 300, a smoke collection duct 400, an electronic control assembly 500 and a stop assembly 600.

[0033] The body 100 is the main structure of the range hood, and has a smoke collecting chamber 110 at the bottom and an air outlet 120 at the top;

[0034] The separator 300 is connected to the body 100 and is disposed in the smoke collecting chamber 110. The separator 300 has an air inlet 310, and the air inlet 310 is communicated with the smoke collecting chamber 110;

[0035] The smoke collecting air duct 400 is disposed in the smoke collecting chamber 110 and between the air outlet 120 and the separator 300;

[0036] The fan assembly 200 is disposed in the machine body and is used to guide the oil smoke to be discharged through the air outlet 120 along the separator 300 and the smoke collecting duct 400 in sequence;

[0037] The electric control component 500 is arranged above the fan component 200, and the electric control component 500 is electrically connected to the fan component 200; in this way, the air duct and the electric control part are separated, which prevents water vapor and dust in the air duct from corroding the circuit components and reduces the maintenance rate of the electric control part. Therefore, the electric control part is separated from the oil circuit, avoiding the internal short circuit and leakage of the power box caused by oil erosion and humid air. Not only does it extend the service life of electrical components such as motors and controllers, but it also reduces the safety hazards caused by electrical problems.

[0038] The stopper assembly 600 includes a stopper plate 610 and an oil leakage pipe 620. The stopper plate 610 is arranged below the fan assembly 200. The oil leakage pipe 620 is connected to the fan assembly 200. The smoke collecting air duct 400 and the oil leakage pipe 620 are separated by the stopper plate 610. Thus, the oil leakage pipe 620 is separated from the smoke collecting air duct 400, which not only forms an independent air duct design and a separate oil discharge structure on the inner side, but also reduces the wind resistance and noise of the oil smoke passing through the oil path accumulation part, so that it is not easy to accumulate oil stains inside the air duct. Even after long-term use, the oil stains in the air duct are relatively less and easier to clean. In this way, the internal air duct can be ensured to be unobstructed, thereby improving the smoke exhaust efficiency.

[0039] In this way, through the design of independent oil circuits, electrical circuits and air ducts, the oil circuit is separated from the air duct, thereby avoiding the accumulation of oil stains in the air duct from oil drainage structures such as oil leakage pipes; by separating the air duct from the electrical circuit, it is prevented that water vapor and dust in the air duct corrode the circuit components, thereby ensuring the stable operation of the electronic control components; by setting the oil circuit, air duct and electrical circuit as a separate structure, the safety of the range hood during use is greatly improved, the overall structure is compact, and the probability of failure of the electronic control part due to interference from oil circuit factors is effectively reduced, thereby reducing the maintenance rate of the range hood.

[0040] Optionally, the fan assembly 200 includes a wind wheel 210, a motor and a volute 220, the volute 220 is arranged in the body 100, the wind wheel 210 is arranged in the volute 220, the motor is connected to the wind wheel 210 to drive the wind wheel 210 to rotate, the electronic control assembly 500 is arranged outside the volute 220, the wind wheel 210 is connected to the air outlet 120 through the volute 220, the stop plate 610 is arranged below the wind wheel 210, and the wind wheel 210 is connected to the air outlet 120 through the volute 220 to form an overall smoke cage structure, increase the smoke cage effect, generate negative pressure through operation, so that the oil smoke passes through the separator 300 and the smoke collecting duct 400 in sequence, and is finally discharged through the air outlet 120 to realize the smoke exhaust function. The stop plate 610 is connected to the volute 220 and is arranged below the volute 220. The oil leakage pipe 620 is arranged on the inner side of the stop plate and is connected to the volute 220, so that the oil leakage pipe can discharge the oil in the volute to prevent the oil from accumulating in the volute, and at the same time is separated from the smoke collection duct 400 by the stop plate 610.

[0041] In some embodiments, the cross-sectional area of ​​the smoke collecting air duct 400 gradually decreases along the direction from the separator 300 to the air outlet 120. That is, the cross-sectional area of ​​the smoke collecting air duct 400 gradually decreases proportionally from one end of the separator 300 to the end close to the air outlet 120, thereby, the gradually decreasing air duct can rectify inside the smoke collecting chamber, reduce noise, and reduce energy loss.

[0042] For example, it can gradually transition from a larger rectangular cross section at the connection with the separator 300 to a smaller rectangular or arc-shaped cross section adapted to the inlet of the fan assembly 200. This tapered design can gradually accelerate the airflow in the air duct, increase the airflow speed, enhance the ability to suck oil smoke, reduce airflow turbulence and eddy currents, make the airflow entering the fan more uniform and stable, and make the airflow received by the fan blades during rotation more balanced, avoiding blade vibration and noise caused by uneven airflow, and also avoiding energy loss caused by local rotation resistance of the fan.

[0043] In addition, the inner wall of the body 100 may also be designed with a smooth transition to avoid sharp corners or bends inside, and to prevent the airflow from changing direction drastically at the bends or corners to generate turbulence. Thus, the proportionally gradually reduced air duct design can reduce noise and energy loss.

[0044] In some embodiments, an upper connecting part 130 and a lower connecting part 140 for connecting to the separator 300 are provided in the body 100, the upper connecting part 130 is provided with a protrusion 131, a first bump bead 320 is provided at the top of the separator 300, the first bump bead 320 is abutted against the protrusion 131, a mounting seat 141 is provided at the bottom of the separator 300, and a mounting hole adapted to the mounting seat 141 is provided on the lower connecting part 140.

[0045] In actual use, the top of the separator is brought close to the position of the upper connecting part, and the first bead 320 on the top of the separator is pressed to make it contact with the raised part 131 of the upper connecting part 130, so that the separator 300 can be locked on the range hood, which simplifies the installation process of the separator and does not require the installation of other fasteners. At the same time, a mounting seat is provided at the bottom of the separator 300, and the mounting seat is used to cooperate and fix with the mounting hole of the lower connecting part. During installation, the mounting seat 141 can be inserted into the mounting hole. After the separator 300 is installed, it is double fixed inside the body, preventing the separator from sagging and deforming due to gravity.

[0046] Since the entire separator 300 is heavy, when the entire separator 300 is installed on the range hood, if only the front panel 340 needs to be operated separately, such as cleaning the front panel 340 or replacing certain components on the front panel 340, in some embodiments, the separator 300 includes a front panel 340 and a rear panel 350, and second beads 341 are respectively provided on both sides of the front panel 340, and a limiting step 352 corresponding to the second beads 341 is provided on the rear panel 350. The front panel 340 and the rear panel 350 are detachably connected through the beads, a protrusion is provided at the bottom of the front panel 340, and a connecting hole matching the protrusion is provided at the bottom of the rear panel 350, and the protrusion can be inserted into the connecting hole.

[0047] When installing the front plate 340 and the rear plate 350, insert the front plate 340 between the two at a certain angle, insert the raised portion at the bottom of the front plate 340 into the connecting hole at the bottom of the rear plate 350 first, and then insert the second bumpers 341 on both sides into the limiting steps to further fix the relative positions of the two and enhance the stability of the connection between the front plate 340 and the rear plate 350.

[0048] Exemplarily, a second bumper 341 is respectively provided on the left and right sides of the front plate 340, and a limiting step 352 is correspondingly provided on the rear plate 350 of the separator 300. When the front plate 340 and the rear plate 350 need to be fixed, the front plate 340 is moved closer to the rear plate 350 so that the left and right second bumpers 341 on the front plate 340 collide with the left and right limiting steps 352 on the rear plate 350, thereby realizing a relatively fixed connection between the front plate 340 and the rear plate 350. Since the second bumpers 341 are tightly pressed against the limiting steps 352, it can ensure that the separator 300 remains stable during daily use and will not easily move or loosen.

[0049] Similarly, when it is necessary to remove the front plate 340, the front plate 340 can be easily separated from the rear plate 350 by pulling the front plate 340 outward so that the second bead 341 is disengaged from the limiting step, so that the front plate 340 can be removed from the rear plate 350 separately without removing the entire separator 300 together. The modular design can reduce maintenance costs, and components can be cleaned or replaced separately during use.

[0050] In addition, the height difference between the top of the side edge of the rear plate 350 and the top of the side edge of the front plate 340 is 1 to 3 mm. In this way, the protruding portion can play a blocking role, preventing the collected oil from overflowing, and allowing the grease separated from the surface frame to flow to the oil collection tank of the range hood, preventing the grease from overflowing the separator due to the airflow during cooking, thereby reducing spillover pollution. Optionally, as Fig.11 In the structure shown, the height difference d between the top of the side edge of the rear plate 350 and the top of the side edge of the front plate 340 is 3 mm. In this way, the protruding end surface of the separation outer plate can form a containment structure to limit the oil stains inside the front plate 340. When the separator is installed at an angle, it can ensure that the oil stains are better guided and collected.

[0051] In some embodiments, a lifting portion is provided above the front plate 340. For example, the lifting portion may be a lug or a groove. By applying force to the lifting portion above the front plate 340 and cooperating with the unlocking action of the bumper, the front plate 340 can be directly lifted and removed. Optionally, the lifting portion may be installed in the center above the front plate 340, so that when lifting, the center of gravity of the front plate 340 can be evenly distributed on both sides of the lifting handle, making the lifting process more stable, reducing the possibility of the separator shaking, and facilitating the separation of the front plate 340 from the separation rear part. Furthermore, the lifting portion and the front plate 340 are integrally die-cast.

[0052] Due to the use of the above-mentioned oil fume separator, it is easy to install and disassemble, and the maintenance cost can be reduced through modular design. The parts can be cleaned or replaced separately during use, and the snap-on connection of the bead can also take into account both lightness and durability.

[0053] It can be understood that the bumping bead is a bumping bead structure well known to those skilled in the art, for example, a bumping bead structure composed of a bead body, a spring and a shell, the shell is used to accommodate the spring and the bead body, when the bead body is squeezed by an external force, the bead body is pressed into the shell, and the spring is compressed; when the external force disappears, the spring pushes the bead body to pop out of the shell and return to the initial position, the specific principle is not repeated here, specifically, when installing, the front plate and the rear plate are aligned and close, the bumping bead is squeezed by the inner wall on one side of the limiting step 352 and retracts, when it moves to the limiting step 352, the spring pushes the bead body to pop out and snap into the limiting step, so as to achieve a fixed connection between the front plate 340 and the rear plate 350. In actual configuration, the number and position of the bumping beads on the front plate 340 or the rear plate 350 can be selected and adjusted according to the needs of connection stability.

[0054] Furthermore, the two ends of the front plate 340 and the rear plate 350 are folded toward the center direction of the separator 300, so that the two ends of the separator 300 are bent along the center. On the basis of the center plane, the separator has a reduced projection area while the total air intake area remains unchanged, which speeds up the wind speed and improves the oil fume absorption effect. Compared with the previous method in which both the front plate and the rear plate are integral flat plates, the oil fume separation effect is better through the folding arrangement.

[0055] See also Figure 6 When the range hood is actually assembled, the two separators bent along the center as above can be used to connect and cooperate at the air inlet, so that an integral smoke cage cavity is formed in the body 100 of the range hood after installation, which has better smoke cage and smoking effects than two separate smoke separators.

[0056] Since the air flow in the air duct often generates aerodynamic noise, in some embodiments, a interlayer 150 is provided on the side of the body 100 opposite to the fan, and a noise reduction layer is provided inside the interlayer 150. The noise reduction layer is provided with sound insulation materials, such as sound insulation cotton or sound insulation boards. By filling the interlayer 150 with sound insulation materials, this part of the noise can be effectively isolated, so that the air flow noise in the air duct can be significantly reduced; secondly, mechanical parts such as motors and fans will also generate vibrations and noise during operation. By providing a noise reduction layer, the mechanical vibration noise heard by the outside world can be greatly reduced, and the range hood is quieter and more stable when in use, thereby improving the user experience.

[0057] In some embodiments, the electric control component 500 includes a top cover plate 510, a sealing box 520 and a power box 530. The top cover plate 510 is provided with an air outlet 511, the air outlet 120 is connected to the air outlet 511, the top cover plate 510 is connected to the sealing box 520 and the cover is arranged above the sealing box 520, the sealing box 520 is arranged on one side of the air outlet 511, the sealing box 520 is provided with an outlet for cables to pass through, and the power box 530 is arranged in the sealing box 520.

[0058] By placing the top cover plate 510 on top of the sealing box 520 and connecting it thereto, impurities such as oil smoke and dust can be prevented from directly entering the interior of the sealing box 520 from above. At the same time, the sealing box 520 is arranged on one side of the air outlet 120 to form an inner and outer double-layer isolation structure, which also allows the power box 530 to be isolated from other internal environments of the range hood, thereby sealing and protecting the interior of the power box 530, reducing the impact of external factors on the power box 530, and further improving the sealing performance.

[0059] Furthermore, the sealing box 520 is formed by enclosing a plurality of side panels, and a receiving cavity is formed between the top cover plate 510 and the plurality of side panels, and the power box 530 is disposed in the receiving cavity. The receiving cavity provides a fixed installation position for the power box 530, making it more stable to install, and the power box can be directly taken out by opening one side panel during maintenance.

[0060] Furthermore, an upper side panel may be provided between the top of the sealing box 520 and the top cover plate 510 to further enhance the sealing of the power box 530. The top cover plate 510 and the side panels are connected to form a closed space, which can effectively isolate the power box 530 from the outside world such as oil smoke, dust, etc., so as to protect the power box 530. In particular, the top cover plate 510 and the sealing box 520 are both sheet metal parts or connected by sheet metal parts, and the top cover plate 510 and the side panels are both formed by an integrated molding process, which can greatly simplify the processing flow and effectively reduce the production cost. Thus, a multiple circuit board sealing structure is formed, which effectively prevents small insects, water vapor, and oil from entering the power box 530, effectively reduces the after-sales maintenance rate of the range hood, and prolongs the service life.

[0061] In addition, the sealing box 520 is provided with a wire outlet for extending the internal power line for wiring, but the wire outlet alone cannot completely guarantee the sealing effect, and oil smoke, water vapor, etc. may still enter the sealing box 520 along the gap between the cable and the wire outlet, causing damage to the internal power box 530, etc. Therefore, in some specific embodiments, a sealing gasket is provided on the sealing box 520, and the sealing gasket cover is provided on the wire outlet, and a plurality of wire outlet holes are provided on the sealing gasket, and the plurality of wire outlet holes are respectively connected to the wire outlet.

[0062] By providing a sealing gasket, the sealing gasket can be accurately covered and connected to the wire outlet through a connector to ensure that the wire outlet hole corresponds to the wire outlet, and then the cable is passed through the wire outlet and the wire outlet hole, and then the sheet metal is used to connect and fix the sealing gasket to the sealing box 520, thereby preventing oil smoke, water vapor, etc. from entering the sealing box 520 through the gap between the wire outlet and the cable, protecting the power box and other components in the sealing box 520 from corrosion, and improving the sealing of the entire cover assembly.

[0063] The sealing pad 540 includes a first connection part and a second connection part, and a plurality of U-shaped holes are respectively provided on the first connection part and the second connection part, and the openings of the U-shaped holes of the first connection part and the second connection part are connected relative to each other to form a wire outlet hole. In this way, the size of the U-shaped hole can be set according to the size of the cable, so that after the connection and matching, the wire outlet hole can better adapt to the shape of different cables, and can be tightly wrapped around the cable after threading, so as to minimize the gap between the cable and the wire outlet hole, thereby effectively preventing impurities such as oil smoke, water vapor, and dust from entering the interior of the sealing box through the gap, improving the overall sealing performance of the sealing box, and further protecting the internal power supply box and other electrical components from the erosion of external oil smoke.

[0064] In order to solve the oil leakage problem of the front separator 300, in some embodiments, an oil guide plate 630 is further provided on the outside of the separator 300, and the oil guide plate 630 is tilted outward toward the front plate of the separator, that is, the top of the oil guide plate 630 tends to be away from the front plate of the separator, so that the height of the top of the oil guide plate 630 is higher than the height of the bottom of the separator 300, and an oil collecting tank 700 is provided at the bottom of the body 100, and the oil collecting tank 700 is respectively connected to the oil leakage pipe 620 and the bottom of the oil guide plate 630. The oil guide plate 630 is tilted, and the top is higher than the bottom of the separator 300. When the oil smoke is separated by the separator 300, the oil droplets therein will adhere to the surface of the separator 300 and flow downward.

[0065] Due to the inclined setting of the oil guide plate 630, the oil droplets will flow downward along the oil guide plate 630 under the action of gravity and be guided to the oil collecting tank 700 at the bottom of the oil guide plate 630. In other words, when the oil droplets accumulate to a certain amount, they will flow to the oil guide plate 630 along the part where the bottom of the face frame of the separator 300 is connected with the oil guide plate 630, or through a specific oil guide channel set on the panel. Under the blocking and guidance of the oil guide plate 630, the oil droplets will flow into the oil collecting tank 700 along the inclined oil guide plate, forming a complete oil leakage prevention path, preventing the oil droplets from leaking from the front end of the separator 300 to the outside of the range hood, and effectively solving the oil leakage problem of the front oil fume separator.
