Description

Technical Field

[0002] For top-suction range hoods, the air intake is located on the top plate. Over long-term use, oil can accumulate on the intake. When the range hood is operating, air flows through the intake into the air collecting chamber, preventing the oil from dripping. After the range hood is turned off, large enough oil droplets can fall from the intake. Related technologies use a movable baffle to close the intake when the range hood is turned off, catching the dripping oil droplets. However, oil that drips onto the movable baffle through the intake easily flows to the edge of the baffle, then overflows onto the lower surface, affecting the surface cleanliness of the range hood.

[0036] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0037] The utility model discloses an external oil guide structure for a range hood, which is used for a range hood. Figures 1 to 3 , comprising: a range hood body 1, which has a top plate 11, and an air inlet 111 is provided on the top plate 11;

[0038] A movable baffle 2 is slidably connected to the bottom of the top plate 11 and is used to open or close the air suction port 111;

[0039] The oil separator bracket 3 is provided on the upper surface of the movable baffle 2, and the oil separator bracket 3 has an oil outlet on the side facing the back plate of the range hood body 1;

[0040] The oil cup 4 is connected to the range hood body 1;

[0041] When the range hood is in operation, the movable baffle 2 opens the air intake port 111; when the range hood is turned off, the movable baffle 2 closes the air intake port 111; the oil separator bracket 3 is arranged around the air intake port 111; the oil dripping onto the movable baffle 2 through the air intake port 111 is blocked by the oil separator bracket 3 and discharged into the oil cup 4 through the oil outlet.

[0042] The external oil guide structure of the range hood of the present invention is arranged in sequence from top to bottom when observing the range hood from the perspective of a user in use.

[0043] In the present invention, the back panel of the range hood body 1 refers to the back panel structure close to the wall after the range hood body 1 is installed.

[0044] When in use, the air inlet 111 is located at the rear end of the top plate 11 relatively close to the wall, and is vertically located obliquely above the gas outlet of the stove. When the user is cooking, the movable baffle 2 slides and opens the air inlet 111 to absorb and exhaust oil smoke through the air inlet 111.

[0045] When the user finishes cooking and turns off the range hood, the movable baffle 2 slides in the opposite direction and closes the air inlet 111 to prevent droplets from falling from the air inlet 111 and to prevent droplets from falling directly onto the kitchen countertop. The oil separator bracket 3 is arranged around the air intake port 111, and the oil separator bracket 3 has an oil outlet on the side facing the back plate of the range hood body 1. When the oil dripping from the air intake port 111 accumulates on the movable baffle 2 and is blocked by the oil separator bracket 3, the oil is located within the range of the oil separator bracket 3, and the oil can only be discharged into the oil cup 4 through the oil outlet on the side facing the back plate of the oil separator bracket 3, and no oil will flow out of the part of the oil separator bracket 3 except the oil outlet. The oil outlet limits the outflow position of the oil, which can ensure that the oil blocked by the oil separator bracket is eventually collected in the oil cup 4, avoiding the problem that the oil dripping onto the movable baffle 2 through the air intake port 111 easily flows to the edge of the movable baffle 2, and then overflows to the lower surface of the movable baffle 2, affecting the surface cleanliness of the range hood.

[0046] Among them, the air intake 111 is relatively located at the rear end of the back plate of the top plate 11 close to the range hood body 1, so that when the movable baffle 2 closes the air intake 111, the oil separator bracket 3 is relatively close to the oil cup 4, reducing the length of the path of the oil flowing in the oil cup 4, thereby realizing rapid collection of the oil.

[0047] Among them, the movable baffle 2 is in an inclined state as a whole, and its inclination angle can be 1°, 2°, 3°, 4° and 5°, etc., and the end of the movable baffle 2 close to the oil cup 4 is the lower end to ensure that the oil flows into the oil cup 4 fully and quickly.

[0048] The external oil guide structure of the range hood of the present invention, the oil separator bracket 3 is U-shaped, including a first part arranged along the width direction of the air intake port 111 and two second parts respectively arranged on both sides of the first part, the two second parts each have a first end and a second end, the first end is connected to the corresponding end of the first part, and the second end extends to the side away from the first part to the rear edge of the movable baffle 2, and an oil outlet is formed between the two second ends.

[0049] The first part and the two second parts are surrounded by the U-shaped oil separator bracket 3, so that when the movable baffle 2 slides in the opposite direction and the air suction port 111 is in a closed state, the air suction port 111 is located in the U-shaped structure formed by the oil separator bracket 3, ensuring that the liquid droplets falling from the air suction port 111 fall into the plate body range formed by the movable baffle 2 corresponding to the oil separator bracket 3, and the first part forms a partition for the oil to flow toward the end of the movable baffle 2 away from the oil cup 4, and the two second parts form a partition for the oil to flow in the width direction of the air suction port 111, thereby preventing the oil from flowing in other directions, and under the guiding action of the two second parts, ensure that the oil flows directly out of the oil outlet and into the oil cup 4, completing a sufficient and rapid oil collection operation.

[0050] The external oil guide structure of the range hood of the present invention is such that the lower surface of the top plate 11 is provided with a slide groove 112 whose shape matches the shape of the oil separator bracket 3. The slide groove 112 includes a horizontal groove corresponding to the first part and two vertical grooves corresponding to the two second parts respectively. The two ends of the horizontal groove are respectively connected to the vertical grooves on the two corresponding sides. The width of the horizontal groove is adapted to the moving path of the movable baffle 2 when opening or closing the air intake port 111.

[0051] The oil separator bracket 3 is installed in the slide groove 112 of the top plate 11, so that the top plate 11, the movable baffle 2 and the oil separator bracket 3 form a trough structure with only an oil outlet and an air intake 111, wherein the air intake 111 serves as the oil inlet for the oil to drip and enter the trough structure, and is an upward opening structure in the vertical direction, and the oil outlet is a horizontal opening structure opening in the horizontal direction, thereby ensuring that the oil dripping from the air intake 111 completely falls into the trough structure, and under the blocking action of the U-shaped oil separator bracket 3 formed by the first part and the two second parts, and under the guiding action of the two second parts, the oil fully flows out from the oil outlet and finally flows into the oil cup 4 without flowing out over the oil separator bracket 3.

[0052] The oil separator 3 is installed in the chute 112, so that the chute 112 limits the movement path of the oil separator 3. At the same time, the oil separator 3 installed in the chute 112 forms a plug-in structure with the top plate 11, forming a limit function for the sliding connection between the movable baffle 2 and the top plate 11, and ensuring the strength of the sliding connection structure between the movable baffle 2 and the top plate 11.

[0053] In addition, the width of the vertical groove corresponds to the width of the corresponding second part, so that the second part is limited by the vertical groove, so that the oil separator bracket 3 can only slide along the groove length direction of the vertical groove.

[0054] The width of the horizontal slot is equal to the length of the path along which the oil-trapping bracket 3 slides. If this path length is represented by points AB, then point A represents the position of the first portion of the oil-trapping bracket 3 when the movable baffle 2 closes the air intake 111. At this point, the first portion of the oil-trapping bracket 3 abuts the slot wall of the horizontal slot near the air intake 111. Point B represents the position of the first portion of the oil-trapping bracket 3 when the movable baffle 2 opens the air intake 111. At this point, the first portion of the oil-trapping bracket 3 abuts the slot wall of the horizontal slot away from the air intake 111.

[0055] The external oil guide structure of the range hood of the present invention, in an exemplary embodiment, is shown in FIG. Figure 3 and Figure 4 The rear side surface of the movable baffle 2 is provided with a first inclined surface 21 connected to its upper surface. The first inclined surface 21 is inclined downward from front to back. The lower edge of the first inclined surface 21 forms the edge of the movable baffle 2 closest to the rear side of the range hood body 1. When the movable baffle 2 closes the air intake port 111, the downward projection of the lower edge of the first inclined surface 21 falls into the oil cup 4.

[0056] When the baffle 2 is moved to close the air intake 111, the oil dripping from the air intake 111 completely falls into the inner plane of the oil separator bracket 3. Under the blocking effect of the first portion and the two second portions surrounding the oil separator bracket 3 to form a U-shape, and under the guiding effect of the two second portions, the oil fully flows out from the oil outlet. When the oil that falls from the air intake 111 into the oil separator bracket 3 and accumulates in the oil separator bracket 3 flows toward the oil outlet and flows out from the oil outlet, the oil first flows through the first inclined surface 21, then flows downward from the lower edge of the first inclined surface 21. Under the action of gravity, the oil falls from the lower edge of the first inclined surface 21 and accelerates towards the oil cup 4 due to the conversion of gravitational potential energy into kinetic energy.

[0057] When the baffle 2 is moved to close the air inlet 111, the downward projection of the lower edge of the first inclined surface 21 falls into the oil cup 4, so that the oil falling from the lower edge of the first inclined surface 21 can accurately fall into the oil cup 4, so that the oil can be accurately collected.

[0058] As a specific solution, the inclination angle of the first inclined surface 21 can be 30°-75°, such as 30°, 40°, 45°, 50°, 55°, 60°, 65°, 70° and 75°.

[0059] The external oil guide structure of the range hood of the present invention, in an exemplary embodiment, is shown in FIG. Figure 3 and Figure 4The rear side surface of the movable baffle 2 is provided with a first inclined surface 21 connected to its upper surface, and the first inclined surface 21 is inclined downward from front to back. The rear side surface of the movable baffle 2 is also provided with a second inclined surface 22 connected to its lower surface, and the second inclined surface 22 is inclined upward from front to back. There is a vertical surface 23 between the first inclined surface 21 and the second inclined surface 22. The upper edge of the vertical surface 23 is connected to the lower edge of the first inclined surface 21, and the lower edge of the vertical surface 23 is connected to the upper edge of the second inclined surface 22. The vertical surface 23 is the surface of the movable baffle 2 closest to the rear side of the range hood body 1. When the movable baffle 2 closes the air intake port 111, the downward projection of the vertical surface 23 falls into the oil cup 4.

[0060] When the self-priming air outlet 111 falls into the oil separator bracket 3 and the oil accumulated in the oil separator bracket 3 flows toward the oil outlet and flows out from the oil outlet, the oil first flows through the first inclined surface 21, and then flows downward from the lower edge of the first inclined surface 21 to the vertical surface 23, and falls from the vertical surface 23 under the action of gravity.

[0061] In this embodiment, the second inclined surface 22 is arranged to be inclined upward from front to back, thereby reducing the contact area between the oil and the vertical surface 23; at the same time, when the oil flows downward from the lower edge of the vertical surface 23, the downward flow direction of the oil is slightly changed by the upper edge of the second inclined surface 22, and the oil flows backward and downward along the second inclined surface 22. Part of the gravitational potential energy of the oil is converted into potential energy of the oil on the second inclined surface 22, so that the oil falling from the vertical surface 23 is dispersed, forming a buffering effect for the direct fall of the oil, preventing the oil from falling directly in the form of drops and hitting the oil cup 4 below, thereby reducing the impact force and noise caused by the direct fall of the oil.

[0062] When the baffle 2 is moved to close the air inlet 111 , the downward projection of the vertical surface 23 falls into the oil cup 4 , so that the oil falling from the vertical surface 23 can accurately fall into the oil cup 4 , so that the oil can be accurately collected.

[0063] As a specific solution, the inclination angle of the first inclined surface 21 and / or the second inclined surface 22 can be 30°-75°, such as 30°, 40°, 45°, 50°, 55°, 60°, 65°, 70° and 75°.

[0064] The external oil guide structure of the range hood of the present invention, in an exemplary embodiment, is shown in FIG. Figure 3 and Figure 4 The rear side surface of the movable baffle 2 includes a first inclined surface 21 and a second inclined surface 22. The first inclined surface 21 is tilted downward from front to back, and the second inclined surface 22 is tilted upward from front to back. The lower edge of the first inclined surface 21 is connected with the upper edge of the second inclined surface 22. When the movable baffle 2 closes the air suction port 111, the downward projection of the lower edge of the first inclined surface 21 falls into the oil cup 4.

[0065] When the self-priming air outlet 111 falls into the oil separator bracket 3 and the oil accumulated in the oil separator bracket 3 flows toward the oil outlet and flows out from the oil outlet, the oil first flows through the upper edge of the first inclined surface 21, and the oil will flow downward along the first inclined surface 21 under the action of gravity. When the oil reaches the lower edge of the first inclined surface 21, the oil falls directly on the oil cup 4 due to inertia, and part of the oil transitions to the upper edge of the second inclined surface 22 and slides a certain path along the second inclined surface 22 under the action of gravity, so that the oil falling from the lower edge of the first inclined surface 21 is dispersed, forming a buffering effect for the direct fall of the oil, preventing the oil from falling directly in the form of drops and hitting the oil cup 4 below, reducing the impact force and noise caused by the direct fall of the oil.

[0066] When the baffle 2 is moved to close the air inlet 111, the downward projection of the lower edge of the first inclined surface 21 falls into the oil cup 4, so that the oil falling from the lower edge of the first inclined surface 21 can accurately fall into the oil cup 4, so that the oil can be accurately collected.

[0067] As a specific solution, the inclination angle of the first inclined surface 21 and / or the second inclined surface 22 can be 30°-75°, such as 30°, 40°, 45°, 50°, 55°, 60°, 65°, 70° and 75°.

[0068] As a parallel scheme of the above-mentioned embodiment, the rear side surface of the movable baffle 2 is provided with a first inclined surface 21 connected to its upper surface, and the first inclined surface 21 is inclined downward from front to back. The rear side surface of the movable baffle 2 is also provided with a second inclined surface 22 connected to its lower surface, and the second inclined surface 22 is inclined upward from front to back. There is a vertical surface 23 between the first inclined surface 21 and the second inclined surface 22. The upper edge of the vertical surface 23 is connected to the lower edge of the first inclined surface 21, and the lower edge of the vertical surface 23 is connected to the upper edge of the second inclined surface 22. When the movable baffle 2 closes the air intake port 111, the downward projection of the lower edge of the second inclined surface 22 falls into the oil cup 4.

[0069] When the oil falls from the vertical surface 23 and enters the oil cup 4 , part of the oil flows downward along the second inclined surface 22 under the influence of viscosity, and finally falls accurately into the oil cup 4 from the lower edge of the second inclined surface 22 .

[0070] Alternatively, as a parallel solution of the above embodiment, the rear side surface of the movable baffle 2 includes a first inclined surface 21 and a second inclined surface 22, the first inclined surface 21 is tilted downward from front to back, and the second inclined surface 22 is tilted upward from front to back, and the lower edge of the first inclined surface 21 is connected with the upper edge of the second inclined surface 22. When the movable baffle 2 closes the air intake port 111, the downward projection of the lower edge of the second inclined surface 22 falls into the oil cup 4.

[0071] When the oil falls from the lower edge of the first slope 21 and enters the oil cup 4, some of the oil flows downward along the second slope 22 under the influence of viscosity, and finally falls accurately into the oil cup 4 from the lower edge of the second slope 22.

[0072] The utility model also discloses a range hood. Figures 1 to 10 , including the external oil guide structure of the above-mentioned range hood, an air collecting chamber a and a telescopic inner chamber b are provided above the top plate 11, an oil guide hole 113 is also provided on the top plate 11, the air suction port 111 and the oil guide hole 113 are connected to the air collecting chamber a, and the telescopic inner chamber b is located in front of the air collecting chamber a; it also includes a driving component 5 provided in the telescopic inner chamber b, and the driving component 5 is used to drive the movable baffle 2 to slide along the top plate 11 to open or close the air suction port 111.

[0073] When the user is cooking, the range hood runs, the driving component 5 is started, and the driving component 5 drives the movable baffle 2 to slide along the top plate and open the air suction port 111. The exhaust fan of the range hood runs and forms a negative pressure in the air collection chamber a. The external oil smoke enters the air collection chamber a through the air suction port 111. In the process of the oil smoke entering the air collection chamber a through the air suction port 111, oil will adhere to the edge of the air suction port 111. When the exhaust fan runs, the air flow in the air collection chamber a is formed, so that the oil adhered to the air suction port 111 is not easily discharged from the air suction port 111. When the user finishes cooking and the smoke exhaust fan is turned off, the driving component 5 drives the movable baffle 2 to slide in the opposite direction and closes the air intake port 111. At this time, if the oil at the air intake port 111 is large enough, the oil will drip from the edge of the air intake port 111 onto the movable baffle 2. Since the oil separator bracket 3 surrounds the air intake port 111, the oil dripping onto the movable baffle 2 is within the range of the oil separator bracket 3, and the oil is guided by the two second parts of the oil separator bracket 3 and flows out from the oil outlet into the oil cup 4.

[0074] After the range hood has been running for a long time, the oil in the smoke collecting chamber a and the oil in the volute of the smoke exhaust fan will gather on the bottom plate of the air collecting chamber a, and drip through the connection between the bottom plate of the air collecting chamber a and the oil guide hole 113 on the top plate 11, and be collected by the oil cup 4.

[0075] See also Figures 6 to 10 The range hood of the present invention also includes a telescopic panel assembly 6, which is slidably connected to the telescopic inner cavity b. The telescopic panel assembly 6 is linked to the movable baffle 2. The driving assembly 5 is connected to the telescopic panel assembly 6. During the process of the driving assembly 5 driving the telescopic panel assembly 6 to extend or retract the telescopic inner cavity b, the movable baffle 2 has a state of relative movement with the telescopic panel assembly 6 and a state of relative stillness with the telescopic panel assembly 6.

[0076] The travel of the telescopic panel assembly 6 is greater than the maximum travel of the movable baffle 2. Since the oil-water separator 3 is fixedly connected to the upper surface of the movable baffle 2, the oil-water separator 3 and the movable baffle 2 are relatively stationary. Under the limitation of the width of the first portion of the chute 112, the maximum travel of the movable baffle 2 is formed, that is, the width of the first portion of the chute 112.

[0077] In this embodiment, a functional device (details will be described later) may be provided at the front end of the telescopic panel assembly 6 , and the functional device is used to assist in the use of the range hood and enhance the user experience.

[0078] As one mode of use, only the portion of the telescopic panel assembly 6 where the functional components are located is extended out of the telescopic inner cavity b. That is, after the range hood is turned on, the telescopic panel assembly 6 moves out of the telescopic inner cavity b. During the process of the telescopic panel assembly 6 extending out of the telescopic inner cavity b, the movable baffle 2 is in a state of relative movement with the telescopic panel assembly 6. That is, when the telescopic panel assembly 6 moves and its front end extends out of the telescopic inner cavity b, the movable baffle 2 remains stationary. When the portion of the telescopic panel assembly 6 where the functional components are located extends out of the telescopic inner cavity, the telescopic panel assembly 6 stops moving out of the telescopic inner cavity b, and the portion of the telescopic panel assembly 6 where the functional components are located extends out of the telescopic inner cavity b. At this time, the movement length of the telescopic panel assembly 6 is L1. When the range hood is turned off, the telescopic panel assembly 6 retracts into the telescopic inner cavity b.

[0079] As the second way of use, the telescopic panel assembly 6 is fully extended from the telescopic inner cavity b, and the movable baffle 2 opens the air suction port 111, that is: after the part of the telescopic panel assembly 6 provided with the functional device is extended from the telescopic inner cavity b, the length of the telescopic panel assembly 6 extended from the telescopic inner cavity b is L1, and then the telescopic panel assembly 6 continues to extend from the telescopic inner cavity b. At this time, the movable baffle 2 moves with the telescopic panel assembly 6. When the movable baffle 2 moves with the telescopic panel assembly 6, the telescopic panel assembly 6 and the movable baffle 2 move synchronously, and the two remain in a relatively static state. When the telescopic panel assembly 6 is extended from the telescopic inner cavity b to a length of L2, the telescopic panel assembly 6 is fully extended from the telescopic inner cavity b, and the movable baffle 2 opens the air suction port 111. At this time, when the smoke exhaust fan is running, the oil smoke will enter the air collecting cavity a through the air suction port 111. Similarly, when the cigarette smoke machine is turned off, the telescopic panel assembly 6 moves before the movable baffle 2. At this time, the telescopic panel assembly 6 and the movable baffle 2 maintain a relative running state, the movable baffle 2 remains stationary, and the air intake 111 is in an open state. When the telescopic panel assembly 6 retracts until the movable baffle 2 covers the functional device on the lower surface, the length of movement of the telescopic panel assembly 6 is L1. At this time, the air intake 111 is in an open state. Continue to move the telescopic panel assembly 6, and the movable baffle 2 begins to move with the telescopic panel assembly 6. The two maintain a relatively stationary state until the telescopic panel assembly 6 is completely retracted into the telescopic inner cavity b, and the movable baffle 2 completely closes the air intake 111.

[0080] In the range hood of the present invention, the process of the telescopic panel assembly 6 extending / retracting the telescopic inner cavity b is divided into a first stage and a second stage. In the first stage, the telescopic panel assembly 6 extends / retracts the telescopic inner cavity b, and the movable baffle 2 is stationary relative to the top plate 11. In the second stage, the telescopic panel assembly 6 extends / retracts the telescopic inner cavity b, and the movable baffle 2 moves with the telescopic panel assembly 6, and the movable baffle 2 moves relative to the top plate 11. After the range hood is turned on, the telescopic panel assembly 6 enters the first stage of extending from the telescopic inner cavity b. In this stage, when the telescopic panel assembly 6 extends out of the telescopic inner cavity b, the movable baffle 2 has a state of relative movement with the telescopic panel assembly 6, that is, when the telescopic panel assembly 6 moves and the front end extends out of the telescopic inner cavity b, the movable baffle 2 remains stationary; after completing the first stage, the part of the telescopic panel assembly 6 provided with functional devices extends out of the telescopic inner cavity b. At this time, the length of movement of the telescopic panel assembly 6 is L1, and then the telescopic panel assembly 6 enters the second stage of extending from the telescopic inner cavity b. In this stage, the telescopic panel assembly 6 continues to extend from the telescopic inner cavity b. At this time, the movable baffle 2 moves with the telescopic panel assembly 6. When the movable baffle 2 moves with the telescopic panel assembly 6, the telescopic panel assembly 6 moves synchronously with the movable baffle 2, and the two remain in a relatively stationary state. When the telescopic panel assembly extends out of the telescopic inner cavity b to a length of L2, the telescopic panel assembly 6 is completely extended out of the telescopic inner cavity b, and the movable baffle 2 opens the air intake 111. After the cigarette smoke machine is turned off, the telescopic panel assembly 6 enters the first stage of retracting the telescopic inner cavity b. In this stage, the telescopic panel assembly 6 moves before the movable baffle 2. At this time, the telescopic panel assembly 6 and the movable baffle 2 maintain a relative running state, the movable baffle 2 remains stationary, and the air intake 111 is in an open state. When the telescopic panel assembly 6 retracts until the movable baffle 2 covers the functional components on the lower surface, the length of the telescopic panel assembly 6 movement is L1. At this time, the first stage ends, and the telescopic panel assembly 6 enters the second stage of retracting the telescopic inner cavity b. In this stage, the telescopic panel assembly 6 continues to retract toward the telescopic inner cavity b, and the movable baffle 2 begins to move with the telescopic panel assembly 6. The two maintain a relatively stationary state until the telescopic panel assembly 6 is completely retracted into the telescopic inner cavity b and the movable baffle 2 completely closes the air intake 111.

[0081] As a specific solution of the above-mentioned functional device, a lighting assembly and / or an air curtain assembly and / or an air quality detection module is provided in the installation cavity of the telescopic panel assembly 6, a wind curtain air inlet hole 62 corresponding to the wind curtain assembly and / or a detection hole 63 corresponding to the air quality detection module is provided on the top plate of the telescopic panel assembly 6, and a wind curtain air outlet hole 64 corresponding to the wind curtain assembly and / or a lighting window 65 corresponding to the lighting assembly is provided on the bottom plate of the telescopic panel assembly 6; when the telescopic panel assembly 6 is extended out of the telescopic inner cavity b, the lighting assembly and / or the air curtain assembly and / or the air quality detection module are extended out of the telescopic inner cavity b along with the telescopic panel assembly 6.

[0082] When the range hood is in use, the drive assembly 5 drives the telescopic panel assembly 6 to extend. The telescopic panel assembly 6 may be partially extended first, while the movable baffle 2 remains stationary, allowing the movable baffle 2 and the telescopic panel assembly 6 to move relative to each other. This allows functional components, such as the lighting assembly, air curtain assembly, and / or air quality detection module, to extend out of the telescopic inner cavity B and be activated. When the range hood is turned off, the drive assembly 5 drives the telescopic panel assembly 6 to retract, reducing the kitchen space occupied by functional components, such as the lighting assembly, air curtain assembly, and / or air quality detection module, when idle.

[0083] In a specific embodiment, a lighting assembly, or an air curtain assembly and an air quality detection module are provided in the installation cavity of the telescopic panel assembly 6, a wind curtain air inlet hole 62 corresponding to the wind curtain assembly and a detection hole 63 corresponding to the air quality detection module are provided on the top plate of the telescopic panel assembly 6, and a wind curtain air outlet hole 64 corresponding to the wind curtain assembly and a lighting window 65 corresponding to the lighting assembly are provided on the bottom plate of the telescopic panel assembly 6; when the telescopic panel assembly 6 is extended out of the telescopic inner cavity b, the lighting assembly, the air curtain assembly and the air quality detection module are extended out of the telescopic inner cavity b along with the telescopic panel assembly 6.

[0084] When the range hood is started, if the distance moved by the telescopic panel assembly 6 is L1, the wind curtain air inlet hole 62 corresponding to the wind curtain assembly and the detection hole 63 corresponding to the air quality detection module provided on the top plate of the telescopic panel assembly 6 are moved out of the telescopic inner cavity b, and the wind curtain air outlet hole 64 corresponding to the wind curtain assembly and the lighting window 65 corresponding to the lighting assembly on the bottom plate of the telescopic panel assembly 6 are moved out of the telescopic inner cavity b. At this time, the lighting assembly in these functional devices can be started to realize the lighting function.

[0085] When the range hood is started, if the telescopic panel assembly 6 is fully extended out of the telescopic inner cavity, the top plate of the telescopic panel assembly 6 is provided with an air curtain inlet hole 62 corresponding to the air curtain assembly and a detection hole 63 corresponding to the air quality detection module extending out of the telescopic inner cavity b, and the air curtain outlet hole 64 corresponding to the air curtain assembly and the lighting window 65 corresponding to the lighting assembly on the bottom plate of the telescopic panel assembly 6 move out of the telescopic inner cavity b. At this time, the air intake 111 is opened. When the smoke exhaust fan is started, the air curtain assembly starts and forms an air curtain between the user and the stove to prevent oil smoke from escaping. The lighting assembly is illuminated to facilitate the user to see the status of the cooking ingredients. The air quality detection module detects the air quality in real time to determine the smoke purification effect of the range hood.

[0086] After the telescopic panel assembly 6 is fully extended out of the telescopic inner cavity, the air curtain assembly, the lighting assembly and the air quality detection assembly are activated. The air curtain assembly draws air through the air curtain inlet hole 62 and exhausts air downward through the air curtain outlet hole 64 to form an air curtain. The air quality detection module draws air through the detection hole 63 to detect the PM2.5 concentration in the air to provide feedback on the purification effect of the oil fume when the range hood is working. The lighting assembly transmits light downward through the lighting window 65, making it easier for the user to observe the ingredients being cooked. After the user completes the cooking operation, the air curtain assembly is closed, the air quality detection module is closed, the lighting assembly is closed, and the drive assembly 5 drives the telescopic panel assembly 6 to retract into the telescopic inner cavity b. After the telescopic panel assembly 6 is fully retracted into the telescopic inner cavity b, the drive assembly 5 stops moving.

[0087] The drive assembly 5 serves as the power source for moving the baffle 2 and the telescopic panel assembly 6. The drive assembly 5 includes a reduction motor 51, a gear 52, and a rack 53. The output end of the reduction motor 51 is coaxially connected to the gear 52, and the rack 53 is connected to the telescopic panel assembly 6. The gear 52 and the rack 53 are meshed and connected. Driven by the reduction motor 51, the drive gear 52 rotates, driving the rack 53 to move, thereby driving the telescopic panel assembly 6 to extend or retract into the telescopic inner chamber b.

[0088] There are two drive assemblies 5, and the racks 53 of the two drive assemblies 5 are respectively connected to the two sides of the telescopic panel assembly 6. The two side walls of the telescopic inner cavity b are provided with guide assemblies 8. The guide assembly 8 includes guide rails and slides. The guide rails are fixedly connected to the two side walls of the telescopic inner cavity b, and the slides are slidably connected to the guide rails. The racks 53 are connected to the telescopic panel assembly 6 and the slides.

[0089] Specifically, the rack 53 is fixedly connected to the telescopic panel assembly 6 and the slide bar at the same time.

[0090] The reduction motor 51 drives the gear 52 to rotate, driving the rack 53 to move, thereby moving the telescopic panel assembly 6 connected to the rack 53. The slide bar is slidably connected to the guide rail, indirectly forming a limit on the extension or retraction length of the telescopic panel assembly 6 through the guide rail.

[0091] See also Figures 6 to 10In the range hood of the present invention, a connecting piece 61 is provided on the telescopic panel assembly 6, and a sliding groove 611 is provided on the connecting piece 61. A connecting assembly 7 is slidably connected to the top plate 11, and the connecting assembly 7 is connected to the movable baffle 2. The connecting assembly 7 has a connecting pin 71, and the connecting pin 71 is slidably connected to the sliding groove 611. The sliding groove 611 has a first end close to the telescopic panel assembly 6 and a second end away from the telescopic panel assembly 6. When the connecting pin 71 slides relatively in the sliding groove 611, the movable baffle 2 is in a state of relative movement with the telescopic panel assembly 6; when the telescopic panel assembly 6 moves and causes the first end or the second end of the sliding groove 611 to apply force to the connecting pin 71, the movable baffle 2 moves with the telescopic panel assembly 6 and is in a state of relative stillness with the telescopic panel assembly 6.

[0092] When the telescopic panel assembly 6 extends out of the telescopic inner cavity b, if the connecting pin 71 is relatively stationary relative to the sliding groove 611, it means that the connecting pin 71 is located at the second end of the sliding groove 611. At this time, the connecting member 61 applies force to the connecting pin 71, so that the connecting assembly 7 drives the movable baffle 2 to move with the telescopic panel assembly 6; when the telescopic panel assembly 6 retracts into the telescopic inner cavity b, if the connecting pin 71 is relatively stationary relative to the sliding groove 611, it means that the connecting pin 71 is located at the first end of the sliding groove 611. At this time, the connecting member 61 applies force to the connecting pin 71, so that the connecting assembly 7 drives the movable baffle 2 to move with the telescopic panel assembly 6.

[0093] In an embodiment of the present invention, the connecting member 61 is a long strip plate-like structure with its length direction along the horizontal opening direction of the telescopic inner cavity b (i.e., the direction of movement of the telescopic panel assembly 6); the length direction of the sliding groove 611 extends along the length direction of the connecting member 61, and it can be a strip groove or a rectangular groove.

[0094] The connecting pin 71 can be a cylindrical pin, a bolt, etc., and its outer diameter is equal to the groove width of the sliding groove 611, so as to form a limit for the connecting pin 71 through the inner wall of the groove width direction of the sliding groove 611, so that the connected connecting component 7 and the movable baffle 2 will only move along the horizontal opening direction of the telescopic inner cavity b.

[0095] In this embodiment, the sliding groove 611 is shown as a strip-shaped groove, and the connecting pin 71 is shown as a cylindrical pin. The sliding groove 611 has a first end close to the telescopic panel assembly 6, specifically the curved inner wall of the sliding groove 611 close to the telescopic panel assembly 6; the sliding groove 611 has a second end away from the telescopic panel assembly 6, specifically the other curved inner wall of the sliding groove 611 away from the telescopic panel assembly 6. The outer diameter of the cylindrical pin is equal to the diameter of the two curved inner walls of the sliding groove 611 to prevent the connecting pin 71 from getting stuck when it abuts the two curved inner walls of the sliding groove 611.

[0096] When the connecting pin 71 slides relatively within the sliding groove 611, the connecting pin 71 slides between the two curved inner walls of the sliding groove 611, which is shown as a strip groove. When the telescopic panel assembly 6 moves and the first end or the second end of the sliding groove 611 applies force to the connecting pin 71, the side surface of the connecting pin 71 abuts against one of the curved inner walls of the sliding groove 611, which is shown as a strip groove.

[0097] When the connecting pin 71 is located at the first end of the sliding slot 611, if the telescopic panel assembly 6 moves in the direction of extending out of the telescopic inner cavity b, the movable baffle 2 will maintain a relative movement state with the telescopic panel assembly 6 until the second end of the sliding slot 611 moves to the connecting pin 71. At this time, if the telescopic panel assembly 6 continues to move in the direction of extending out of the telescopic inner cavity b, the movable baffle 2 moves with the telescopic panel assembly 6 and maintains a relatively stationary state relative to the telescopic panel assembly 6; when the connecting pin 71 is located at the second end of the sliding slot 611, if the telescopic panel assembly 6 moves in the direction of retracting the telescopic inner cavity b, the movable baffle 2 will maintain a relative movement state with the telescopic panel assembly 6 until the first end of the sliding slot 611 moves to the connecting pin 71. At this time, if the telescopic panel assembly 6 continues to move in the direction of retracting the telescopic inner cavity b, the movable baffle 2 moves with the telescopic panel assembly 6 and maintains a relatively stationary state relative to the telescopic panel assembly 6.

[0098] The distance between the first end and the second end of the sliding groove 611 is the maximum distance that the telescopic panel assembly 6 moves before the movable baffle 2. The telescopic panel assembly 6 and the movable baffle 2 move relative to each other. When this distance is reached, the connecting pin 71 abuts against the second end from the first end, or abuts against the first end from the second end. If the telescopic panel assembly 6 continues to move, the telescopic panel assembly 6 and the movable baffle 2 move synchronously, and the two remain relatively stationary.

[0099] When the connecting pin 71 is located at the first end of the sliding groove 611, when the telescopic panel assembly 6 moves in the direction of extending out of the telescopic inner cavity b, the connecting member 61 does not apply force to the connecting pin 71. At this time, the connecting pin 71 slides relative to the sliding groove 611, and the second end of the sliding groove 611 approaches the connecting pin 71. After the second end of the sliding groove 611 moves to the connecting pin 71, the telescopic panel assembly 6 continues to move in the direction of extending out of the telescopic inner cavity b, the connecting member 61 will apply force to the connecting pin 71, and the connecting member 61 drives the connecting assembly 7 to move through the connecting pin 71, so that the connecting assembly 7 drives the movable baffle 2 to move, so that the movable baffle 2 and the telescopic panel assembly 6 remain relatively stationary.

[0100] When the telescopic panel assembly 6 is fully extended from the telescopic inner cavity b and the movable baffle 2 opens the air intake port 111, the connecting pin 71 is located at the second end of the sliding groove 611. After shutting down, the telescopic panel assembly 6 begins to move in the direction of retracting the telescopic inner cavity b. At this time, the first end of the sliding groove 611 moves toward the connecting pin 71, and the connecting pin 71 slides relatively in the sliding groove 611. The movable baffle 2 and the telescopic panel assembly 6 move relative to each other. When the first end of the sliding groove 611 moves to the connecting pin 71, when the telescopic panel assembly 6 continues to slide into the telescopic inner cavity b, the connecting member 61 will apply force to the connecting pin 71, and the connecting member 61 causes the connecting assembly 7 to drive the movable baffle 2 to move through the connecting pin 71, so that the movable baffle 2 and the telescopic panel assembly 6 remain in a relatively static state.

[0101] See also Figures 6 to 10 In the range hood of the present invention, a avoidance groove 114 is provided on the top plate 11, the connecting component 7 is slidably connected to the top of the top plate 11 and is arranged corresponding to the avoidance groove 114, and a baffle bracket 24 is provided on the movable baffle 2, the baffle bracket 24 is slidably connected to the avoidance groove 114, and the baffle bracket 24 is connected to the connecting component 7.

[0102] The baffle bracket 24 is arranged vertically, and includes a vertical rod and a horizontal plate. The lower end of the vertical rod is fixedly connected to the movable baffle 2, and the upper end passes through the avoidance groove 114 and extends above the top plate 11. The horizontal plate is fixedly connected to the upper end of the vertical rod and is connected to the connecting component 7 through multiple screws.

[0103] Through the setting of the avoidance groove 114, the connecting component 7 is connected to the movable baffle 2 through the baffle bracket 24, and through the avoidance setting of the avoidance groove 114, when the movable baffle 2 and the telescopic panel assembly 6 move synchronously, the avoidance groove 114 can form a movement avoidance for the baffle bracket 24.

[0104] The connecting assembly 7 includes a guide member 72 and a sliding member 73 . The guide member 72 is provided above the top plate 11 . The sliding member 73 is slidably connected to the guide member 72 . The baffle bracket 24 is connected to the sliding member 73 . The sliding member 73 is provided with a connecting pin 71 .

[0105] The guide member 72 can be a long rail structure arranged along the horizontal opening direction of the telescopic inner cavity b, which is provided with an upwardly opening chute, such as: the guide member 72 can be made of U-shaped steel. The lower end of the sliding member 73 is adapted and slidably connected to the upwardly opening chute of the guide member 72.

[0106] Based on the above embodiment, the horizontal plate of the baffle bracket 24 is connected to the sliding member 73 by multiple screws and is connected to the rear end of the sliding member 73. The connecting member 61 is located above the front end of the sliding member 73, and the connecting pin 71 provided at the front end of the sliding member 73 is slidably connected to the sliding groove 611 of the connecting member 61.

[0107] When the movable baffle 2 and the telescopic panel assembly 6 move synchronously, driven by the connecting pin 71, the sliding member 73 slides relative to the guide member 72, and the baffle bracket 24 connected to the sliding member 73 slides synchronously, thereby driving the movable baffle 2 to move synchronously through the moving baffle bracket 24.

[0108] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
