Description

Technical Field

[0001] This utility model relates to a range hood and a kitchen system including the range hood. Background Technology

[0002] Range hoods are usually installed above the stove and can quickly remove and exhaust the waste from the stove and the harmful fumes produced during cooking, playing an important role in maintaining the kitchen environment and human health.

[0003] However, when the air intake surface of the range hood is connected to other components (such as the connection between the oil collection box and the air intake surface), a sealed connection is not used. This means that when the range hood is absorbing fumes, fumes or outside air can also enter through the gaps. This causes the negative pressure of the range hood to be unable to concentrate at each air intake, reducing the efficiency of the air intake in absorbing fumes. As a result, the possibility of fumes escaping increases, affecting the user's experience. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defect that the negative pressure of the existing range hood cannot be concentrated at each air inlet, and to provide a range hood and a kitchen system including the range hood.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] This utility model discloses a range hood, which includes a smoke collection hood and a fan. The smoke collection hood has an air inlet on its air intake surface facing the stove. The inside of the smoke collection hood is provided with an air intake channel. The air intake end of the air intake channel is connected to the air inlet, and the air outlet end of the air intake channel is connected to the fan.

[0007] The range hood also includes a first wind deflector, which is connected inside the smoke collection hood and located below the fan. The projection of the first wind deflector on the axial direction of the air outlet completely covers the area in the smoke collection hood where the air outlet is not located.

[0008] In this solution, the aforementioned structural form allows the fan to adsorb cooking fumes through the air inlet channel and air inlets during operation. Because the first baffle is located below the fan, and its projection completely covers the area of ​​the fume hood without the air outlet along the axial direction of the outlet, cooking fumes entering from other gaps cannot reach the fan. This concentrates negative pressure at each air inlet, improving the efficiency of fume adsorption, reducing the possibility of fume escape, and enhancing the user experience.

[0009] Preferably, there are multiple air inlets and multiple air inlets, and the multiple air inlets and multiple air inlets are connected in a one-to-one correspondence, and the multiple air inlets are arranged circumferentially around the first wind deflector.

[0010] In this solution, the above-mentioned structural form is adopted, with multiple air inlets and multiple air inlet channels set up one-to-one, which can avoid mutual interference of oil fumes in different areas and ensure that the oil fumes entering the fume hood can be better absorbed by the fan.

[0011] Preferably, the range hood further includes a ventilation component and a dividing component. The ventilation component is connected to the smoke collection hood and has a ventilation cavity inside. The ventilation cavity is connected to each of the air inlets. The dividing component is disposed in the ventilation cavity to divide the ventilation cavity into multiple air inlet channels.

[0012] In this solution, the above-mentioned structural form is adopted. Through the dividing component, the ventilation cavity can be divided into multiple independent air intake channels, which can avoid mutual interference of oil fumes in different areas, help reduce noise and vibration, and make the range hood quieter and more stable during operation while ensuring that the oil fumes can be better absorbed.

[0013] Preferably, the range hood further includes a connector and a fan frame, both of which are located inside the smoke collection hood, and the ventilation component is connected to the fan frame via the connector.

[0014] Preferably, the range hood further includes a plurality of second baffles, each of which is configured to correspond one-to-one with the air inlet channel. The second baffles are movably connected to the wall of the air inlet channel and are used to switch the opening and closing of the air inlet channel.

[0015] In this solution, the aforementioned structural form allows the air intake channel to be opened and closed as needed. When cooking is being done on one side of the stove, the second baffle on that side can be opened, while the second baffle on the other side can be closed. This allows the negative pressure to be better concentrated on the side where the second baffle is opened, improving the efficiency of the air intake on that side in adsorbing oil fumes, reducing the possibility of oil fumes escaping, and enhancing the user experience.

[0016] Preferably, the range hood further includes a pushing member, the rotating end of the second wind deflector being rotatable relative to the wall of the air inlet channel, the pushing member being connected to the end of the second wind deflector away from the rotating end, for driving the second wind deflector to rotate around the rotating end.

[0017] In this solution, the above-mentioned structural form is adopted, and the second wind baffle can be rotated around the rotating end by the pusher, so that the second wind baffle can rotate relative to the air inlet channel, thereby realizing the opening and closing of the air inlet channel.

[0018] Preferably, the pushing member includes a push rod, one end of which is rotatable relative to the wall of the air inlet channel, and the other end of which is connected to the end of the second baffle member away from the rotating end;

[0019] Wherein, the extension and retraction direction of the push rod is not parallel to the first direction, the first direction being the direction of the line connecting the connection point of the push rod and the second windshield to the rotating end.

[0020] In this solution, the above-mentioned structure is adopted. The push rod can apply a pushing force or a pulling force to the second windshield. Under the action of the pushing force or the pulling force, the second windshield can rotate around the rotating end, so that the second windshield can rotate relative to the air inlet channel, thereby realizing the opening and closing of the air inlet channel.

[0021] Preferably, the pusher further includes a fixing part, one end of which is rotatably connected to the push rod, and the other end of which is connected to the end of the second windshield member away from the rotating end.

[0022] In this solution, the above-mentioned structural form is adopted, and the connection between the push rod and the second wind deflector is realized through the fixing part, so that the push rod can apply pushing and pulling forces to the second wind deflector through the fixing part, and the second wind deflector can rotate relative to the air inlet channel.

[0023] Preferably, the pushing component further includes a motor and a motor shaft, with both ends of the motor shaft connected to the motor and the end of the second windshield component away from the rotating end, respectively, and the motor is used to drive the motor shaft to rotate.

[0024] In this solution, the above-mentioned structure is adopted. The motor can drive the second baffle to rotate relative to the rotating end through the motor shaft, thereby enabling the second baffle to rotate relative to the air inlet channel, thus realizing the opening and closing of the air inlet channel.

[0025] This utility model also discloses a kitchen system, which includes a range hood as described in any of the preceding claims.

[0026] In this solution, the aforementioned structural form is adopted to apply the range hood to the kitchen system. When the range hood is working, the fan can adsorb cooking fumes through the air inlet channel and air inlets. Since the first baffle is located below the fan, and its projection completely covers the area of ​​the fume hood without the air outlet along the axial direction of the air outlet, cooking fumes entering from other gaps cannot reach the fan. This allows the negative pressure to be concentrated at each air inlet, enabling each inlet to better adsorb cooking fumes, improving the efficiency of fume adsorption, reducing the possibility of fume escape, and enhancing the user experience.

[0027] The positive and progressive effects of this utility model are as follows:

[0028] When the range hood is working, the fan can adsorb cooking fumes through the air inlet channel and air inlets. Because the first baffle is located below the fan, and its projection completely covers the area of ​​the fume hood without an air outlet along the axial direction of the air outlet, cooking fumes entering from other gaps cannot reach the fan. This allows the negative pressure to be concentrated at each air inlet, enabling each inlet to better adsorb cooking fumes, improving the efficiency of fume adsorption, reducing the possibility of fume escape, and enhancing the user experience.

[0059] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0060] like Figures 1 to 8As shown, this embodiment provides a range hood 100, which includes a smoke collection hood 1 and a fan. The smoke collection hood 1 has an air inlet 111 on its air inlet surface 11 facing the cooktop. An air inlet channel 3 is provided inside the smoke collection hood 1, with the air inlet end of the channel 3 connected to the air inlet 111 and the air outlet end of the channel 3 connected to the fan. The range hood 100 also includes a first baffle 4, which is connected inside the smoke collection hood 1 and located below the fan. The projection of the first baffle 4 along the axial direction of its air outlet completely covers the area of ​​the smoke collection hood 1 without an air outlet. With this structure, when the range hood 100 is working, the fan can absorb cooking fumes through the air inlet channel 3 and the air inlet 111. Since the first baffle 4 is located below the fan, and its projection completely covers the area of ​​the air inlet surface 11 without an air outlet in the axial direction of the air outlet, the fumes entering from other gaps cannot reach the fan. This allows the negative pressure to be concentrated at each air inlet 111, enabling each air inlet 111 to better absorb fumes, improving the efficiency of each air inlet 111 in absorbing fumes, reducing the possibility of fumes escaping, and improving the user experience.

[0061] It needs to be specifically explained that, such as Figure 2 As shown, the first baffle 4 is provided to cut off the gap between the air inlet surface 11 and other components and the passage before the fan, so that the negative pressure generated by the fan in the smoke hood 1 can be concentrated only at each air inlet 111. In actual use, the air inlets 111 opened on the air inlet surface 11 have the same function as the conventional air inlets 111 in the range hood 100, which is to realize the connection between the inside of the smoke hood 1 and the outside. In addition, the gaps mentioned above include the gap at the connection between the oil collection box and the air inlet surface 11, as well as the gap at the connection between the air inlet channel 3 and the air inlet 111.

[0062] Furthermore, taking the vertical direction of the air inlet axis as an example, let's explain how the projection of the first wind deflector 4 on the air outlet axis completely covers the area in the smoke hood 1 where no air outlet is provided: Since the air inlet axis is vertical, the projection of the first wind deflector 4 on the air outlet axis is located in the horizontal plane, so that in the horizontal plane, no area in the smoke hood 1 where no air outlet is provided is exposed outside the projection of the wind deflector 4.

[0063] In this embodiment, the first windbreak 4 is plate-shaped. In other embodiments, the shape of the first windbreak 4 can be adjusted according to actual needs, and is not limited here. Additionally, as... Figure 2 The image shows the fan installation position 2.

[0064] If a new air intake channel 3 is needed later, a corresponding through hole can be opened on the baffle. The air intake channel 3 can be connected to the through hole to achieve the connection between the new air intake channel 3 and the fan. In addition, since the first baffle 4 is located below the fan, it can also prevent oil stains adhering to the fan from dripping onto the air intake surface 11 and dripping out from the gap between the air intake surface 11 and other components.

[0065] like Figure 3 and Figure 4 As shown, there are multiple air inlets 111 and multiple air inlet channels 3, with each air inlet 111 and air inlet channel 3 connected in a one-to-one manner. The multiple air inlet channels 3 are arranged circumferentially around the first baffle 4. By adopting the above structural form, the one-to-one arrangement of multiple air inlets 111 and multiple air inlet channels 3 can avoid mutual interference of oil fumes from different areas, ensuring that the oil fumes entering the fume hood 1 can be better adsorbed by the fan.

[0066] like Figure 1 As shown, in specific use, taking a wall-mounted range hood 100 as an example, the position of the air inlet 111 will be explained. The smoke collection hood 1 includes a mounting surface, which is used to mount the range hood 100 on the wall. Some air inlets 111 are located on the side of the air intake surface 11 away from the mounting surface. For most range hoods 100, the mounting surface is located on the rear side of the smoke collection hood 1, so some air inlets 111 are located in the area near the front of the air intake surface 11, thereby controlling the fumes escaping from the front and preventing smoke from escaping. The remaining air inlets 111 are located on the left and right sides of the air intake surface 11, which can control the fumes escaping from the left and right sides and prevent smoke from escaping. In addition, due to the obstruction of the wall, the fumes escaping from the rear, front, back, left, and right directions can be controlled, reducing the probability of smoke escaping. In other embodiments, the location of the air inlet 111 and the type of range hood 100 can be adjusted according to actual needs, and are not specifically limited here.

[0067] like Figure 4 and Figure 5 As shown, the range hood 100 also includes a ventilation component 5 and dividing components 6. The ventilation component 5 is connected to the smoke collection hood 1, and a ventilation cavity 51 is formed inside the ventilation component 5. The ventilation cavity 51 is connected to each air inlet 111. Multiple dividing components 6 are disposed inside the ventilation cavity 51 to divide the ventilation cavity 51 into multiple air inlet channels 3. With the above-mentioned structural form, the ventilation cavity 51 can be divided into multiple independent air inlet channels 3 by the dividing components 6, thereby avoiding mutual interference of oil fumes in different areas, which helps to reduce the generation of noise and vibration. While ensuring that oil fumes can be better absorbed, it makes the range hood quieter and more stable during operation.

[0068] In this embodiment, as Figure 3 and Figure 4As shown, the range hood 100 also includes multiple smoke guides 10, and each smoke guide 10 has a smoke guide channel inside. Each smoke guide channel is connected to each air inlet 111 and each air inlet channel 3 in a one-to-one correspondence, thereby realizing the connection and communication between the air inlet 111 and the air inlet channel 3 through the smoke guide 10.

[0069] like Figure 4 and Figure 5 As shown, the range hood 100 also includes a connector 7 and a fan frame, both of which are located inside the smoke collection hood 1. The ventilation component 5 is connected to the fan frame via the connector 7. Specifically, the connector 7 includes a first connecting portion and a second connecting portion. The first connecting portion has a connecting hole for connecting to the fan. The second connecting portion extends horizontally outward from the bottom of the first connecting portion, and the connection between the connector 7 and the ventilation component 5 is achieved through the second connecting portion.

[0070] It should be noted that, as shown in Figure 5, the dividing piece 6 extends from the inlet of the ventilation channel to the outlet of the ventilation cavity 51, thereby connecting the inlet of each ventilation channel to the air inlet 111. This allows fumes to reach the outlet of the ventilation channel after passing through it. The connecting piece 7 is located at the outlet of the ventilation cavity 51 and is arranged circumferentially around the outlet, thereby increasing the contact area between the ventilation component 5 and the fan frame, and improving the stability and reliability of the connection between the ventilation component 5 and the fan frame.

[0071] In this embodiment, the dividing member 6 is plate-shaped. In other embodiments, the shape of the dividing member 6 can be adjusted according to actual needs, and is not limited here.

[0072] like Figure 6 As shown, the range hood 100 also includes multiple second baffles 8, each corresponding to an air inlet channel 3. The second baffles 8 are movably connected to the wall of the air inlet channel 3, used to switch the air inlet channel 3 open and closed. This structure allows the air inlet channel 3 to be opened and closed as needed. When cooking is being done on one side of the stove, the corresponding second baffle 8 can be opened, while the second baffles 8 on other sides can be closed. This allows the negative pressure to be better concentrated on the side where the second baffle 8 is open, improving the efficiency of the air inlet 111 in absorbing fumes on that side, reducing the possibility of fumes escaping, and enhancing the user experience.

[0073] It should be specifically noted that the second wind deflector 8 mentioned above is movably connected to the wall of the air inlet channel 3. This connection can be either a rotatable connection between the second wind deflector 8 and the wall of the air inlet channel 3, a slidable connection between the second wind deflector 8 and the wall of the air inlet channel 3, or other connections that allow the second wind deflector 8 to move relative to the wall of the air inlet channel 3, thereby enabling the air inlet channel 3 to open and close.

[0074] In addition, the second wind baffle 8 can be disposed inside the air inlet channel 3, or at the air inlet end or air outlet end of the air inlet channel 3. In this embodiment, the second wind baffle 8 is disposed at the air outlet end of the air inlet channel 3. In other embodiments, the second wind baffle 8 can also be disposed in other areas of the air inlet channel 3. The specific placement of the second wind baffle 8 is not limited here.

[0075] Please see Figures 6 to 8 To understand this, the range hood 100 also includes a pushing component 9. The rotating end of the second baffle 8 can rotate relative to the wall of the air inlet channel 3. The pushing component 9 is connected to the end of the second baffle 8 away from the rotating end, and is used to drive the second baffle 8 to rotate around the rotating end. With the above structure, the pushing component 9 enables the second baffle 8 to rotate around the rotating end, allowing the second baffle 8 to rotate relative to the air inlet channel 3, thereby realizing the opening and closing of the air inlet channel 3.

[0076] It should be specifically noted that the rotating end of the aforementioned second wind deflector 8 can rotate relative to the wall of the air inlet channel 3 in several ways: Firstly, the rotating end of the second wind deflector 8 is rotatably connected to the wall of the air inlet channel 3; secondly, the rotating end 81 of the second wind deflector 8 is rotatably connected to another adjacent second wind deflector 8, thereby allowing the second wind deflector 8 to rotate relative to the wall of the air inlet channel 3. Alternatively, the second wind deflector 8 can be rotatably connected to other components, thereby allowing the second wind deflector 8 to rotate relative to the wall of the air inlet channel 3.

[0077] like Figure 7 As shown, the pushing component 9 includes a push rod 91. One end of the push rod 91 is rotatable relative to the wall of the air inlet channel 3, and the other end of the push rod 91 is connected to the end of the second baffle 8 away from the rotating end. The extension / retraction direction of the push rod 91 is not parallel to a first direction, which is the direction of the line connecting the connection point of the push rod 91 and the second baffle 8 to the rotating end. With this structure, the push rod 91 can apply a pushing or pulling force to the second baffle 8. Under the action of the pushing or pulling force, the second baffle 8 can rotate around the rotating end, allowing it to rotate relative to the air inlet channel 3, thereby realizing the opening and closing of the air inlet channel 3.

[0078] It should be noted that the ability of one end of the aforementioned push rod 91 to rotate relative to the wall of the air inlet channel 3 can be implemented in several ways: Firstly, one end of the push rod 91 is rotatably connected to the wall of the air inlet channel 3; secondly, one end of the push rod 91 is rotatably connected to a second baffle 8 adjacent to the push rod 91, thereby allowing one end of the push rod 91 to rotate relative to the wall of the air inlet channel 3. Alternatively, one end of the push rod 91 can be rotatably connected to other components, allowing the wall of the second baffle 8 to rotate relative to the wall of the air inlet channel 3.

[0079] like Figure 7 As shown, the pusher 9 also includes a fixing part 92. One end of the fixing part 92 is rotatably connected to the push rod 91, and the other end of the fixing part 92 is connected to the end of the second wind deflector 8 away from the rotating end. With the above structure, the connection between the push rod 91 and the second wind deflector 8 is achieved through the fixing part 92, so that the push rod 91 can apply pushing and pulling forces to the second wind deflector 8 through the fixing part 92, allowing the second wind deflector 8 to rotate relative to the air inlet channel 3.

[0080] It should be specifically noted that the first direction mentioned above is the direction of the line connecting the connection point between the fixed part 92 and the second windbreak 8 to the rotating end.

[0081] like Figure 8 As shown, the pusher 9 also includes a motor 93 and a motor shaft 94. The two ends of the motor shaft 94 are connected to the motor 93 and the end of the second baffle 8 furthest from the rotating end, respectively. The motor 93 drives the motor shaft 94 to rotate. With this structure, the motor 93 can drive the second baffle 8 to rotate relative to the rotating end via the motor shaft 94, thereby allowing the second baffle 8 to rotate relative to the air inlet channel 3, thus realizing the opening and closing of the air inlet channel 3.

[0082] In this embodiment, the pusher 9 also includes a fixing block 95, and the fixing block 95 is fixedly connected to the inner wall of the smoke hood 1. One end of the motor shaft 94 is connected to the motor 93, and the other end of the motor shaft 94 passes through the fixing block 95 and is connected to the second windshield 8.

[0083] In this embodiment, please refer to 6 to Figure 8To understand this, the rotating end 81 of the second wind deflector 8 located on the front side is opposite to the rotating end 81 of the second wind deflector 8 located on the side side, and the two rotating ends 81 of the two second wind deflectors 8 are rotatably connected by a rotating shaft 20. For these two second wind deflectors 8, the push rod 91 can drive one of the second wind deflectors 8 to rotate relative to the wall of the air inlet channel 3 through the fixing part 92. At this time, the end of the push rod 91 away from the fixing part 92 is rotatably connected to the second wind deflector 8 located on the side side. The motor 93 drives the motor shaft 94 to drive the other second wind deflector 8 to rotate relative to the wall of the air inlet channel 3. Since the rotating ends 81 of the two second wind deflectors 8 are rotatably connected by the rotating shaft 20, when the motor 93 drives the second wind deflector 8 to rotate through the motor shaft 94, the other second wind deflector 8 can follow the rotation of the first second wind deflector 8, so that both second wind deflectors 8 can rotate, thereby simultaneously opening or closing the two air inlet channels 3.

[0084] This embodiment also provides a kitchen system including a range hood 100. Using the above-described structure, the range hood 100 is applied to the kitchen system. When the range hood 100 is working, the fan can absorb cooking fumes through the air inlet duct 3 and the air inlet 111. Since the first baffle 4 is located below the fan, and its projection completely covers the area of ​​the air inlet surface 11 without an air outlet in the axial direction of the air outlet, cooking fumes entering from other gaps cannot reach the fan. This allows the negative pressure to be concentrated at each air inlet 111, enabling each air inlet 111 to better absorb cooking fumes, improving the efficiency of fume absorption, reducing the possibility of fume escape, and enhancing the user experience.

[0085] In practical use, the kitchen system is a combination of commonly used kitchen utensils such as the range hood 100 and stove.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
