Description

Technical Field

[0001] This application relates to the field of range hood technology, and in particular to a wind guide structure and a fan range hood. Background Technology

[0002] The main body of a range hood can be divided into two parts: the fan section and the range hood section. The main function of the range hood section is to extract cooking fumes, while the main function of the fan section is to circulate airflow in the kitchen to cool it down. The fan section mainly cools the head and upper limbs of the cook by blowing high-speed airflow towards them.

[0003] Currently, the air outlet guide plate of fan range hoods is usually a fixed structure, which means that the guide plate cannot be disassembled after production and installation. This results in the guide plate being difficult to disassemble and clean, affecting the user experience. Utility Model Content

[0004] Therefore, it is necessary to provide an air guiding structure and a fan-type range hood to address the problems of difficult disassembly and cleaning of the air guide plate.

[0005] An air guiding structure, the air guiding structure comprising:

[0006] The housing component has an air outlet, the air outlet having two inner walls facing each other in a first direction, each inner wall having a guide groove, the openings of the two guide grooves being arranged opposite each other, and each guide groove being closed at one end in its longitudinal direction, and the other end penetrating to the end face of the housing having the air outlet and forming an insertion port.

[0007] The air guide plate has an insertion part at each of its opposite ends in the first direction. Each insertion part can enter or exit one of the guide grooves through the insertion port, and when the insertion part is located in the guide groove, the insertion part can move along the guide groove.

[0008] An anti-detachment component is provided on the housing component, and one of the guide grooves is divided into an installation section and a disassembly section. The anti-detachment component can be controllably switched between a locked state and an unlocked state. When the anti-detachment component is in the locked state, it prevents the insertion part from moving between the installation section and the disassembly section. When the anti-detachment component is in the unlocked state, it allows movement between the installation section and the disassembly section.

[0009] In one embodiment, the air guide structure includes two anti-detachment components, which are disposed corresponding to the two guide grooves. Each anti-detachment component is used to divide the corresponding guide groove into an installation section and a disassembly section. Each anti-detachment component is used to allow or prevent the movement of the insertion part in the corresponding guide groove.

[0010] In one embodiment, the anti-detachment component is configured to switch from the locked state to the unlocked state when subjected to an external force, and to switch from the unlocked state to the locked state when the external force is removed or reduced.

[0011] When the anti-detachment component is in the locked state, the insertion part can abut against the anti-detachment component during the movement along the guide groove, and apply an external force to switch the anti-detachment component from the locked state to the unlocked state.

[0012] In one embodiment, the anti-detachment member is deformably disposed on the housing member relative to the housing member under external force. When the anti-detachment member deforms relative to the housing member, the anti-detachment member switches from the locked state to the unlocked state. When the anti-detachment member returns to its original shape, the anti-detachment member switches from the unlocked state to the locked state.

[0013] In one embodiment, the anti-detachment component includes a connecting portion and a main body portion. One end of the connecting portion is connected to the housing component, and the main body portion is disposed at the opposite end of the anti-detachment component. The main body portion protrudes from the connecting portion on the side facing the guide groove, and the projection of the main body portion in a first direction is at least partially located within the guide groove.

[0014] In one embodiment, the width of the main body gradually decreases in the longitudinal direction of the guide groove away from the connecting portion.

[0015] In one embodiment, when the insertion part is located in the mounting section and the anti-detachment member is in the locked state, one end of the insertion part in the extension direction of the guide groove abuts against the end face of the closed end of the guide groove, and the other side abuts against the anti-detachment member.

[0016] In one embodiment, the air guiding structure further includes a guide rail protruding from the inner wall of the air outlet and extending longitudinally along the edge of one of the guide grooves. The insertion port is located at one end of the guide rail, and the anti-detachment component is located at the opposite end of the guide rail.

[0017] In one embodiment, the circumferential surface of the insertion portion is an arc surface.

[0018] In one embodiment, the guide groove is provided in a tortuous extension.

[0019] A fan-type range hood includes an air guide structure as described in any of the preceding claims.

[0020] In the aforementioned air guide structure, when installing the air guide plate, align the two insertion parts of the air guide plate with the two insertion ports, so that the two insertion parts are inserted into the two guide grooves respectively, allowing the two insertion parts to move within their corresponding guide grooves. The insertion part just inserted into the insertion port is in the disassembly section. At this point, switch the anti-detachment device to the unlocked state and move the insertion part, allowing it to pass through the anti-detachment device into the installation section. Since the installation section is connected to the closed end of the guide groove, switch the anti-detachment device to the locked state, and the insertion part will be fixed in the installation section, thus securing the air guide plate.

[0021] When the air guide plate needs to be disassembled, the anti-detachment component can be switched to the unlocked state, allowing the insertion part to move to the disassembly section. The insertion part then continues to move to the insertion port, finally exiting the guide groove from the insertion port, completing the disassembly of the air guide plate. Thus, simply switching the anti-detachment component's state allows for the disassembly and installation of the air guide plate, effectively facilitating user convenience. This allows users to easily remove the air guide plate for separate cleaning, making the process simple, convenient, and reliable, thus improving the user experience. Attached Figure Description

[0037] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

[0040] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0041] See Figure 1 , Figure 1 The diagram shows a schematic of the air guide structure of a fan-type range hood according to an embodiment of this application. The air guide structure provided in this embodiment is used in a fan-type range hood. The air guide structure includes a housing 10, an air guide plate 30, and an anti-detachment component 40. The housing 10 has an air outlet 11, which is used to connect to the air duct of the fan-type range hood. The motor of the fan-type range hood drives the impeller to rotate, thereby generating airflow through the impeller. The airflow is input to the air outlet 11 through the air duct and finally blown towards the user through the air outlet to achieve the effect of cooling the user.

[0042] Among them, see Figure 2 , Figure 3 and Figure 6 The air outlet has two opposing inner walls 12 in the first direction X. Each inner wall 12 has a guide groove 13. The openings of the two guide grooves 13 are opposite each other in the first direction X. Each guide groove 13 is closed at one end in its longitudinal direction, and the other end extends through to the end face of the housing with the air outlet to form an insertion port 14. The air guide plate 30 has insertion parts 31 at both opposite ends in the first direction X. Each insertion part 31 can enter and exit one of the guide grooves 13 through the insertion port 14. When the two insertion parts 31 are respectively inserted into the two guide grooves 13, the middle part of the air guide plate 30 will be located at the air guide hole, thereby guiding the airflow output from the air guide hole through the air guide plate 30 and blowing the airflow towards the user.

[0043] When the insertion part 31 is located in the guide groove 13, the insertion part 31 can move along the guide groove 13, allowing the insertion part 31 to extend into the interior of the guide groove 13. To prevent the insertion part 31 from detaching from the insertion port 14 of the guide groove 13 under the action of external force, an anti-detachment member 40 is provided on the housing part 10 and recessed near one of the guide grooves 13. The anti-detachment member 40 can divide the adjacent guide groove 13 into an installation section 15 and a disassembly section 16. The installation section 15 is connected to the closed end of the guide groove 13, and the disassembly section 16 is connected to the end of the guide groove 13 with the insertion port 14.

[0044] The anti-disengagement component 40 can be controlled to switch between a locked state and an unlocked state. When the anti-disengagement component 40 is in the locked state, it is located on the movement path of one of the insertion parts 31 along the corresponding guide groove 13 and prevents the insertion part 31 from moving along the guide groove 13. When the anti-disengagement component 40 is in the unlocked state, it allows the insertion part 31 to move along the guide groove 13.

[0045] In actual use, when the air guide plate 30 needs to be installed, align the two insertion parts 31 of the air guide plate 30 with the two insertion ports 14 respectively, so that the two insertion parts 31 of the air guide plate 30 are inserted into the two guide grooves 13 respectively, and the two insertion parts 31 move in the corresponding guide grooves 13 respectively. The insertion part 31 that is just inserted into the insertion port 14 is located in the disassembly section 16. At this time, switch the anti-detachment component 40 to the unlocked state and move the insertion part 31, so that the insertion part 31 can enter the installation section 15 through the anti-detachment component 40. Since the installation section 15 is connected to the closed end of the guide groove 13, switch the anti-detachment component 40 to the locked state, and the insertion part 31 will be fixed in the installation section 15, thereby fixing the air guide plate 30.

[0046] When it is necessary to disassemble the air guide plate 30, the anti-detachment component 40 can be switched to the unlocked state, allowing the insertion part 31 to move to the disassembly section 16. Then, the insertion part 31 continues to move to the insertion port 14, and finally exits the guide groove 13 from the insertion port 14, completing the disassembly of the air guide plate 30. Thus, simply switching the state of the anti-detachment component 40 allows for the disassembly and installation of the air guide plate 30, effectively facilitating user assembly and disassembly. This allows users to remove the air guide plate 30 for separate cleaning, making the process simple, convenient, and reliable, thus improving the user experience.

[0047] In some embodiments of this application, see [reference] Figure 4 and Figure 5The air guide structure includes two anti-detachment components 40, which are corresponding to two guide grooves 13. Each anti-detachment component 40 is used to divide the corresponding guide groove 13 into an installation section 15 and a disassembly section 16. Each anti-detachment component 40 is used to allow or prevent the movement of the insertion part 31 in the corresponding guide groove 13. Thus, when the two insertion parts 31 of the air guide plate 30 are respectively located in the installation sections 15 of the two guide grooves 13, the two insertion parts 31 can be fixed by the two anti-detachment components 40, so that both ends of the air guide plate 30 can be stably fixed on the housing 10, ensuring the installation effect of the housing 10.

[0048] It is understood that in some other embodiments, only one anti-detachment component 40 may be provided, and one end of the air guide plate 30 may be fixed while the other end of the air guide plate 30 is not fixed, or it may be fixed by screws or other means, which is not limited here.

[0049] To ensure the effective fixation of the anti-detachment component 40 on the insertion part 31, when the insertion part 31 is located in the installation section 15 and the anti-detachment component 40 is in the locked state, one end of the insertion part 31 in the extension direction of the guide groove 13 abuts against the end face of the closed end of the guide groove 13, and the other side abuts against the anti-detachment component 40. In other words, when the insertion part 31 is located in the installation section 15, the insertion part 31 is limited on all sides by the guide groove 13 or the anti-detachment component 40. At this time, the insertion part 31 cannot move along the guide groove 13, so that the insertion part 31 can be stably fixed in the guide groove 13 without being subjected to a large external force, thereby improving the installation effect of the air guide plate 30.

[0050] In some embodiments of this application, the anti-disengagement member 40 is configured to switch from a locked state to an unlocked state when subjected to an external force, and to switch from an unlocked state to a locked state when the external force is removed or reduced. When the anti-disengagement member 40 is in the locked state, after the user inserts the insertion part 31 into the port 14, the user continues to move the insertion part 31, causing the insertion part 31 to move along the guide groove 13. During the movement of the insertion part 31 along the guide groove 13, the insertion part 31 can abut against the anti-disengagement member 40 and apply an external force for the anti-disengagement member 40 to switch from the locked state to the unlocked state. At this time, the anti-detachment component 40 will move toward the locked state under the action of the external force from the insertion part 31 until the user applies a large enough external force to the air guide plate 30. The air guide plate 30 then applies an external force to the anti-detachment component 40 through the insertion part, and the anti-detachment component 40 will switch to the unlocked state, thereby allowing the insertion part 31 to continue moving to the installation section 15. After that, the anti-detachment component 40 restores its deformation and fixes the insertion part 31 in the installation section 15. At this time, the installation of the air guide plate 30 can be completed.

[0051] Conversely, when the user needs to disassemble the air guide plate 30, external force can be applied to the air guide plate 30, and the air guide plate 30 will then apply external force to the anti-detachment component 40 through the insertion part 31. The anti-detachment component 40 will switch to the unlocked state, thereby moving the insertion part from the installation section 15 to the disassembly section 16. Finally, the air guide plate 30 will continue to move, so that the disassembly component will continue to move to the insertion port 14, thus completing the disassembly of the air guide plate 30.

[0052] In some embodiments, the anti-detachment member 40 is deformably disposed on the housing member 10 relative to the housing member 10 under external force. When the anti-detachment member 40 deforms relative to the housing member 10, the anti-detachment member 40 switches from a locked state to an unlocked state. When the anti-detachment member 40 returns to its original shape, the anti-detachment member 40 switches from an unlocked state to a locked state. In actual use, the anti-detachment member 40 is a plastic part with a certain degree of elasticity. When the insertion part 31 abuts against the anti-detachment member 40, the anti-detachment member 40 will deform. If the force applied by the insertion part 31 to the anti-detachment member 40 is large enough, the anti-detachment member 40 will deform to the unlocked state, thereby allowing the insertion part 31 to switch between the disassembly section 16 and the installation section 15.

[0053] Thus, when the user needs to disassemble the air guide plate 30, they can pull the air guide plate 30 forcefully, applying sufficient external force to the anti-detachment member 40 through the insertion part 31 of the air guide plate 30. This causes the anti-detachment member 40 to deform, allowing the insertion part 31 to move from the installation section 15 to the disassembly section 16, and finally pull it out from the insertion port 14, completing the disassembly of the air guide plate 30. When the user needs to install the air guide plate 30, after inserting the insertion part 31 into the port 14, the insertion part 31 can be moved along the guide groove 13 until it abuts against the anti-detachment member 40, causing the anti-detachment member 40 to deform. This allows the insertion part 31 to move from the disassembly section 16 to the installation section 15. The anti-detachment member 40 then returns to its original shape, fixing the insertion part 31 within the installation section 15, thus completing the installation of the air guide plate 30.

[0054] It should be noted that when the air guide structure is provided with two anti-detachment parts 40, the structures of the two anti-detachment parts 40 are consistent. When the user installs and removes the air guide plate 30, the movement process of the insertion parts 31 at both ends of the air guide plate 30 is consistent. That is, the movement process of the other insertion part 31 in the corresponding guide groove 13 is the same as the movement process of the insertion part 31 mentioned above. The above only describes the movement process of one of the insertion parts 31 in the corresponding guide groove 13, and will not be repeated here.

[0055] Furthermore, the anti-detachment component 40 is integrally formed with the housing component 10, and the anti-detachment component 40 includes a connecting portion 41 and a main body portion 42. One end of the connecting portion 41 is connected to the housing component 10, and the main body portion 42 is located at the opposite end of the anti-detachment component 40. The projection of the main body portion 42 in the first direction X is at least partially located within the guide groove 13. Thus, when the insertion portion 31 moves along the guide groove 13, the insertion portion 31 abuts against the main body portion 42 and pushes the main body portion 42 to fold around the end of the connecting portion 41 located in the housing component 10, thereby causing the main body portion 42 to move away from the guide groove 13 until the insertion portion 31 passes over the main body portion 42, completing the switching of the insertion portion 31 between the installation section 15 and the disassembly section 16.

[0056] Furthermore, along the longitudinal direction of the guide groove 13, the width of the main body 42 gradually decreases away from the connecting part 41. The main body 42 is narrower away from the top of the connecting part 41 and wider near the bottom of the connecting part 41, thus the main body 42 presents a triangular shape. In this way, two inclined guide surfaces 43 can be formed on opposite sides of the main body 42 along the longitudinal direction of the guide groove 13. Whether the insertion part 31 moves from the disassembly section 16 to the installation section 15, or from the installation section 15 to the disassembly section 16, the insertion part 31 can abut against the guide surfaces 43, allowing the insertion part 31 to apply an oblique force to the main body 42 through the guide surfaces 43. This makes it easier for the main body 42 to fold over the connecting part 41, and further makes it easier for the insertion part 31 to pass over the main body 42, thus making the movement of the insertion part 31 between the disassembly section 16 and the installation section 15 smoother.

[0057] It should be noted that in other embodiments, the anti-detachment component 40 can be disposed on the housing component 10 by means of an elastic element such as a spring. When the insertion part 31 applies external force to the anti-detachment component 40, the external force can compress the elastic element such as the spring, causing the anti-detachment component 40 to switch from the locked state to the unlocked state. When the insertion part 31 no longer applies external force, the spring element returns to its deformation, causing the anti-detachment component 40 to switch from the unlocked state to the locked state, thus completing the reset of the anti-detachment component 40. In still some embodiments, the anti-detachment component 40 can also be manually operated to switch between the locked and unlocked states.

[0058] In some embodiments of this application, the air guiding structure further includes a guide rail 50, which protrudes from the inner wall 12 of the air outlet 11 and extends longitudinally along the edge of one of the guide grooves 13. An insertion port 14 is located at one end of the guide rail 50, and an anti-detachment member 40 is located at the opposite end of the guide rail 50. Thus, when the insertion part 31 enters the insertion port 14, the insertion part 31 moves along the guide rail 50, making it easier for the insertion part 31 to contact the guide rail 13 under the action of the guide rail 50. Conversely, after the insertion part 31 moves to the disassembly section 16, it is also easier for the insertion part 31 to move to the insertion port 14 under the action of the guide rail. The guide rail 50 also has the effect of preventing the insertion part 31 from detaching from the guide groove 13. Optionally, two guide rails 50 are included, and the two guide rails 50 are respectively disposed near the two guide grooves 13.

[0059] Optionally, the anti-detachment component 40 is connected to the guide rail component 50, and the anti-detachment component 40, the guide rail component 50 and the housing component 10 are all integrally formed to improve the connection strength between the anti-detachment component 40, the guide rail component 50 and the housing component 10.

[0060] Further, see Figure 6 and Figure 7 The circumferential surface of the insertion part 31 is arc-shaped. This arc-shaped surface, through contact with the inner wall 12 of the guide groove 13 or the guide rail 50, reduces the friction between the insertion part 31 and the guide groove 13 and guide rail 50, thereby improving the smoothness of the insertion part 31's movement within the guide groove 13 and guide rail. Optionally, the two insertion parts 31 can be two guide posts respectively disposed at both ends of the air guide plate 30.

[0061] In some embodiments of this application, both the guide groove 13 and the guide rail 50 are arranged in a tortuous manner. Even if the insertion part 31 accidentally falls into the disassembly section 16, the tortuous extension of the guide groove 13 prevents the insertion part 31 from falling directly out of the insertion port 14, reducing the risk of the air guide plate 30 falling off accidentally. Optionally, the extension trajectory of the guide groove 13 and the guide rail is a 90° zigzag line.

[0062] This application also provides a fan-driven range hood, which includes the above-mentioned air guiding structure. Since the fan-driven range hood includes all the technical features of the above-mentioned air guiding structure, it possesses all the technical effects of the above-mentioned air guiding structure, which will not be elaborated here.

[0063] The above-mentioned air guiding structure has at least the following advantages:

[0064] When the user needs to disassemble the air guide plate 30, they can pull the air guide plate 30 forcefully, applying sufficient external force to the anti-detachment member 40 through the insertion part 31. This causes the anti-detachment member 40 to deform, allowing the insertion part 31 to move from the installation section 15 to the disassembly section 16, and finally pull it out from the insertion port 14, completing the disassembly of the air guide plate 30. When the user needs to install the air guide plate 30, after inserting the insertion part 31 into the port 14, the insertion part 31 moves along the guide groove 13 until it abuts against the anti-detachment member 40, causing the anti-detachment member 40 to deform. This allows the insertion part 31 to move from the disassembly section 16 to the installation section 15. The anti-detachment member 40 then returns to its original shape, fixing the insertion part 31 within the installation section 15, thus completing the installation of the air guide plate 30. The operation is simple, convenient, and reliable, improving the user experience.

[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
