Description

Technical Field

[0001] The utility model relates to the field of kitchen appliances, in particular to a range hood. Background Art

[0002] A drawer-type range hood is a range hood installed inside a kitchen cabinet. When a user uses the range hood, the user pulls open the baffle of the range hood to expose the air suction port, and the range hood starts to exhaust oil fumes. When not in use, the baffle is pushed back and closed, and the range hood shuts down.

[0003] In the related art, in order to facilitate user operation, a pulley slide rail structure is usually arranged between the baffle and the casing, so that the baffle slides relative to the casing through the pulley slide structure, so that the baffle can be easily pulled out and pushed in to facilitate the user to turn on the range hood.

[0004] However, the pulley slide rail structure is relatively flexible. If the installation accuracy of the range hood is not high or the light baffle is not parallel to the ground, the baffle is easily slid out of the casing under the action of collision or its own weight, affecting the user experience. Summary of the Utility Model

[0005] An embodiment of the utility model provides a range hood, which solves the problem of poor fixing effect of the baffle of the drawer-type range hood.

[0006] To achieve the above object, the embodiment of the utility model adopts the following technical solutions:

[0007] In a first aspect, an embodiment of the present application provides a range hood, which includes a casing, a slide rail, a baffle, a fixing member, a clamping member and a hook. The casing forms a receiving cavity and an air suction port communicating the receiving cavity with the outside. The slide rail is connected to the casing. The baffle is arranged at the air suction port, and the baffle is slidably connected to the slide rail. The baffle is used to open and close the air suction port.

[0008] The fixing member is arranged in the receiving cavity, and the fixing member is connected to the casing. The hook is arranged in the receiving cavity. The hook includes a rod body and a clamping portion connected to the rod body. The rod body is rotatably connected to the fixing member.

[0009] When the baffle closes the air suction port, the clamping portion rotates to the side of the clamping member away from the fixing member, and the clamping portion abuts against the clamping member, so that the clamping portion locks the clamping member.

[0010] Moreover, the rod body connected to the clamping portion is rotatably connected to the fixing member, and the fixing member is connected to the casing. Therefore, when the clamping portion of the hook abuts against the clamping member, the hook can lock the clamping member, thereby fixing the file, thereby limiting the baffle to prevent the baffle from sliding out of the casing. In this way, when the baffle closes the air suction port, it can be firmly connected to the casing, and the baffle is not easily disengaged from the casing, thereby improving the user experience.

[0011] In some embodiments, the fixing member includes a fixing housing, a first connecting rod, and a slider. The fixing housing is connected to the housing of the range hood. One end of the first connecting rod is rotatably connected to the fixing housing. The slider is slidably connected to the fixing housing. An annular groove is provided on the first surface of the slider. The first surface is parallel to the sliding direction of the baffle. The other end of the first connecting rod is slidably connected to the annular groove. When the baffle closes the air suction opening, the first connecting rod abuts against the inner wall surface of the annular groove on the side close to the baffle.

[0012] In some embodiments, a first recessed portion is formed on the inner wall surface of the annular groove on the side close to the baffle. When the baffle closes the air suction opening, the other end of the first connecting rod is located within the first recessed portion.

[0013] In some embodiments, the bottom wall surface of the annular groove includes a plurality of stepped surfaces connected end to end in sequence. For any two adjacent stepped surfaces, the distance between the leading end of one of them and the first surface is less than the distance between the trailing end of the other stepped surface and the first surface.

[0014] In some embodiments, the range hood further includes a resilient member. One end of the resilient member is connected to the slider, and the other end of the resilient member is connected to the fixing housing.

[0015] In some embodiments, the fixing housing is rotatably connected to a rod body, the slider is connected to the rod body, and the slider can push the hook to rotate during the sliding process.

[0016] In some embodiments, the range hood further includes a sliding member. The sliding member is connected to the rod body. The slider is formed with a chute, and the sliding member is slidably connected to the chute. The sliding member can drive the hook during the sliding process.

[0017] In some embodiments, the rod body includes a first connecting portion and a second connecting portion. One end of the first connecting portion is rotatably connected to the fixing housing, and the other end is snap-connected to the clamping portion.

[0018] One end of the second connecting portion is connected to the first connecting portion. The second connecting portion is located on the side of the first connecting portion close to the fixing member. The other end of the second connecting portion is connected to the sliding member.

[0019] In some embodiments, the fixing housing forms a cavity, the slider is disposed in the cavity and can slide within the cavity. The fixing member further includes a second connecting rod. One end of the second connecting rod is connected to the slider. When the baffle closes the air suction opening, the other end of the second connecting rod contacts the baffle.

[0020] In a second aspect, an embodiment of the present application provides a range hood, which includes a housing, a slide rail, a baffle, a fixing member, a clamping member, and a hook. The housing forms a receiving cavity and an air suction opening communicating the receiving cavity with the outside. The slide rail is connected to the housing. The baffle is disposed at the air suction opening. The baffle is slidably connected to the slide rail. The baffle is used to open and close the air suction opening.

[0021] The fixing member is connected to the casing. The hook is arranged in the accommodating cavity. The hook includes a rod body and a clamping portion connected to the rod body. The rod body is rotatably connected to the fixing member. When the baffle closes the air suction port, the clamping portion rotates to the side of the clamping member away from the fixing member, and the clamping portion abuts against the clamping member.

[0022] For the beneficial effects described in the second aspect of this application, reference can be made to the analysis of the beneficial effects in the first aspect, which will not be elaborated here. Description of the Drawings

For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations. In addition, when describing pipelines or channels, the terms "connection" and "connection" used in the present application have the meaning of conducting. The specific meaning needs to be understood in combination with the context.

[0042] In the embodiments of the present application, words such as "exemplary" or "for example" are used to represent examples, illustrations or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions.

[0043] As used herein, "about", "substantially" or "approximate" includes the stated value and the average value within an acceptable deviation range of the specific value, where the acceptable deviation range is determined by those of ordinary skill in the art considering the measurement being discussed and the errors associated with the measurement of the specific quantity (i.e., the limitations of the measurement system).

[0044] The drawer-type range hood, also known as the pull-out range hood, see Figure 1 , the range hood is designed in a drawer-like structure and can be hidden inside the cabinet without occupying extra space, making the kitchen cleaner and more beautiful.

[0045] Specifically, see Figure 2 , when the user needs the range hood to work, the user can pull open the baffle 300 that blocks the range hood, see Figure 3 , when the user does not use the range hood, the user pushes the baffle 300 back and closes it. This design not only saves kitchen space but also is very convenient to operate.

[0046] See Figure 4 , in the related art, in order to facilitate the user to open and close the baffle 300, a slide rail assembly is provided between the baffle 300 and the housing 100, so that the baffle 300 can be easily slid out and pushed in.

[0047] Among them, the slide rail assembly includes a slide rail 200 and a slide bar. One of the slide rail 200 and the slide bar is arranged on the side wall of the baffle 300, and the other of the slide rail 200 and the slide bar is arranged on the inner side wall of the housing 100, and the slide rail 200 and the slide bar are slidably connected.

[0048] The slide rail assembly further includes a spring piece 201 arranged on the slide rail 200. The spring piece 201 is used to release and lock the slide bar. When the baffle 300 closes the air inlet 101, the baffle 300 presses the spring piece 201. After the spring piece 201 is compressed, it generates a force on the baffle 300, thereby locking the slide bar, so that the baffle 300 can be fixed at the corresponding position.

[0049] However, the force generated by the spring piece 201 on the baffle 300 is small. Only by the method of fixing the baffle 300 with the spring piece 201, the baffle 300 cannot be in a stable fixed state.

[0050] To solve the above technical problems, an embodiment of the present application provides a range hood, which solves the problem of poor fixing effect of the baffle 300 of the drawer-type range hood.

[0051] In some embodiments, referring to Figure 5 , the range hood provided by the present application further includes a blower 103. When the blower 103 operates, a negative pressure area is generated in the accommodation cavity 102. At this time, the cooking fume can be attracted by the negative pressure area and enter the accommodation cavity 102. Then, oil-gas separation is carried out in the accommodation cavity 102, the oil particles are condensed into oil droplets and collected through the oil path, and the purified flue gas is discharged outdoors.

[0052] In some embodiments, continuing to refer to Figure 4 , the range hood in the present application includes a slide rail 200, and the slide rail 200 is connected to the casing 100.

[0053] The slide rail 200 can provide support and guidance for the baffle 300 to ensure that the baffle 300 can run smoothly when being pulled out and pushed in, without shaking or jamming.

[0054] At the same time, when the baffle 300 closes the air suction port 101, the baffle 300 is connected to the closing mechanism composed of the elastic piece 201 and the micro switch in the slide rail 200, so that the baffle 300 can be fixed.

[0055] In some embodiments, referring to Figure 6 , the range hood in the present application includes a baffle 300, the baffle 300 is arranged at the air suction port 101, and the baffle 300 is slidably connected to the slide rail 200. The baffle 300 is used to open and close the air suction port 101.

[0056] Specifically, the side wall of the baffle 300 is provided with a slide bar, the slide bar is slidably connected to the slide rail 200, and the baffle 300 can slide between a first position and a second position along the arrangement direction of the slide rail 200 through the slide bar. When the slide rail 200 is located at the first position, the baffle 300 closes the air suction port 101; when the slide rail 200 is located at the second position, the baffle 300 completely opens the air suction port 101.

[0057] In some embodiments, referring to Figure 7 , the range hood in the present application further includes a clamping member 800, the clamping member 800 is connected to the baffle 300, and the baffle 300 can be clamped to the casing 100 through the clamping member 800. Thus, when the baffle 300 closes the air suction port, it can be firmly connected to the casing 100 and is not easy to slip off.

[0058] In some embodiments, referring to Figure 8 , the range hood in the present application further includes a fixing member 400, which is connected to the casing 100.

[0059] Among them, the fixing member 400 can be located inside the accommodation cavity 102 or outside the housing 100. Hereinafter, an example will be given with the fixing member 400 located inside the accommodation cavity 102.

[0060] Exemplarily, in order to increase the space utilization rate of the range hood, the slide rail 200 is arranged inside the accommodation cavity 102, and the baffle 300 can slide in the accommodation cavity 102 through the slide rail 200.

[0061] Exemplarily, in order to facilitate the user to push and pull the baffle 300 and timely observe the sliding condition of the baffle 300, the slide rail 200 is arranged on the outer wall of the housing 100, and the baffle 300 can slide on the outer wall of the housing 100 through the slide rail 200.

[0062] It should be noted that the baffle 300 can slide along a direction perpendicular to the plane where the air suction port 101 is located, and can also slide along a direction parallel to the plane where the air suction port 101 is located. The present application does not limit this. The following content will take the baffle 300 sliding along a direction parallel to the plane where the air suction port 101 is located as an example for illustration.

[0063] In some embodiments, referring to Figure 9 and combining Figure 8 and Figure 7 , the range hood in the present application includes a hook 700 which is slidably connected to the fixing member 400. When the baffle 300 closes the air suction port 101, the hook 700 is clamped with the baffle 300. When the baffle 300 closes the air suction port 101, the hook 700 is disengaged from the baffle 300.

[0064] It should be noted that the hook 700 can be arranged inside the accommodation cavity 102 or outside the housing 100. The present application does not limit this. The following content will take the hook 700 arranged inside the accommodation cavity 102 as an example for illustration.

[0065] In this way, when the baffle 300 closes the air suction port 101, the fixing member 400 plays a limiting role on the hook 700, and the hook 700 is clamped with the clamping member 800. Further, the fixing member 400 can also play a further fixing role on the baffle 300.

[0066] Further, the hook 700 includes a rod body 701 and a clamping portion 702 connected to the rod body 701. The rod body 701 is rotatably connected to the fixing member 400. When the baffle 300 closes the air suction port 101, the clamping portion 702 rotates to the side of the clamping member 800 away from the fixing member 400, and the clamping portion 702 abuts against the clamping member 800.

[0067] Exemplarily, the clamping member 800 is a clamping plate, and the clamping portion 702 of the hook 700 can rotate to the wall surface on the side of the clamping plate close to the baffle 300 so that the hook 700 is clamped with the clamping plate.

[0068] Thus, the position of the baffle 300 is further fixed, preventing the baffle 300 from accidentally detaching from the casing 100 when closing the air suction opening 101 due to poor fixing effect of the slide rail 200 or the casing 100 on the baffle 300, which affects the user experience.

[0069] Therefore, in this application, by providing the fixing member 400 and the hook 700 between the casing 100 and the baffle 300, the fixing effect of the baffle 300 when closing the air suction opening 101 can be further enhanced.

[0070] Specifically, refer to Figure 8 and combine with Figure 9 , Figure 8 which is a schematic diagram of the position of the baffle 300 when the baffle 300 closes the air suction opening 101 in this application, Figure 9 which is a schematic diagram of the position of the baffle 300 when the baffle 300 opens the air suction opening 101 in this application.

[0071] In some embodiments, refer to Figure 10 , the fixing member 400 in this application includes a fixing shell 401, and the fixing shell 401 is connected to the casing 100. The fixing shell 401 can effectively isolate and protect the internal components of the fixing member 400 from damage by dust, dirt and other external environmental factors, reducing the possibility of faults and damages.

[0072] Moreover, it can make the internal components of the fixing member 400 work without being interfered by the work of external components (such as the fan 103 of the range hood), further improving the stability of the working process of the fixing member 400.

[0073] In some embodiments, refer to Figure 11 and combine with Figure 10 , the fixing member 400 of this application includes a first connecting rod 402. One end of the first connecting rod 402 is rotatably connected to the fixing shell 401. By cooperating the first connecting rod 402 with the hook 700, the connection structure between the casing 100 and the baffle 300 in this application is made simpler.

[0074] Wherein, the first connecting rod 402 includes a connecting rod 4022 and a limiting rod 4021. One end of the connecting rod 4022 is rotatably connected to the fixing shell 401, and the other end of the connecting rod 4022 is fixedly connected to the limiting rod 4021.

[0075] Exemplarily, one end of the connecting rod 4022 of the first connecting rod 402 is rotatably connected to the fixing shell 401 through a hinge.

[0076] Exemplarily, one end of the connecting rod 4022 of the first connecting rod 402 is rotatably connected to the fixing shell 401 through a pin shaft.

[0077] It should be noted that the limiting rod 4021 and the connecting rod 4022 can be integrally formed, or the limiting rod 4021 and the connecting rod 4022 can be connected by welding. This application does not make any limitation in this regard.

[0078] In some embodiments, continue to refer to Figure 10 , the fixing member 400 in this application further includes a slider 403, and the slider 403 is slidably connected to the fixing shell 401.

[0079] Exemplarily, the slider 403 is slidably connected to the outer shell of the fixing shell 401.

[0080] Another exemplarily, continue to refer to Figure 14 and Figure 11 , the fixing shell 401 forms a cavity 4011, the slider 403 is located in the cavity 4011, and the slider 403 can slide in the cavity 4011. Wherein, the shape and size of the slider 403 match the shape and size of the cavity 4011, so that when the slider 403 slides in the cavity 4011, it can only slide along one direction and will not deviate from the sliding direction.

[0081] At the same time, it can also reduce the shaking generated when the slider 403 slides in the cavity 4011, making the sliding of the slider 403 in the cavity 4011 more stable.

[0082] Furthermore, an annular groove 4032 is provided on the first surface 4031 of the slider 403. The first surface 4031 is parallel to the sliding direction of the baffle 300, and the other end of the first connecting rod 402 is slidably connected to the annular groove 4032. It can be understood that the limiting rod 4021 of the slider 403 is slidably connected to the annular groove 4032.

[0083] On the one hand, the annular groove 4032 can effectively limit the sliding range of the first connecting rod 402, thereby achieving precise positioning and sliding control to ensure that the first connecting rod 402 can slide within a preset range, further ensuring the stability of the slider 403 during the sliding process.

[0084] On the other hand, the annular groove 4032 can provide good support and positioning for the first connecting rod 402, keep the first connecting rod 402 stable during the movement process, reduce vibration and swing, and improve the stability and working efficiency of the system.

[0085] At this time, when the baffle 300 closes the air suction port 101, the limiting rod 4021 of the first connecting rod 402 abuts against the inner wall surface of the annular groove 4032 on the side close to the baffle 300. The wall surface of the annular groove 4032 can clamp the first connecting rod 402 here, so that the slider 403 is fixed at this position, thereby fixing the baffle 300 here. At this time, the fixed position of the baffle 300 is the position where the baffle 300 closes the air suction port 101.

[0086] In some embodiments, referring to Figure 10 , a first recess 40321 is formed on the inner wall surface of the annular groove 4032 on the side close to the baffle 300. When the baffle 300 closes the air suction port 101, the other end of the first connecting rod 402 is located in the first recess 40321.

[0087] That is, when the baffle 300 closes the air suction port 101, the limiting rod 4021 of the first connecting rod 402 is located in the first recess 40321, and the limiting rod 4021 of the first connecting rod 402 abuts against the wall surface of the first recess 40321. Thus, the first connecting rod 402 and the slider 403 are relatively fixed, and along the sliding direction of the baffle 300, the first connecting rod 402 cannot continue to slide. Therefore, the baffle 300 can be locked to prevent the baffle 300 from accidentally sliding out.

[0088] In some embodiments, referring to Figure 11 and Figure 12 , the bottom wall surface of the annular groove 4032 includes a plurality of stepped surfaces 40322 connected end to end in sequence. For any two adjacent stepped surfaces 40322, the distance between the leading end of one of them and the first surface 4031 is less than the distance between the trailing end of the other stepped surface 40322 and the first surface 4031.

[0089] In this way, when the first connecting rod 402 slides in the annular groove 4032, it can only slide from the stepped surface 40322 with a larger distance from the first surface 4031 to the stepped surface 40322 with a smaller distance from the first surface 4031. The annular groove 4032 plays a guiding role for the first connecting rod 402. The stepped surface 40322 can ensure that the first connecting rod 402 slides in a fixed direction, and the first connecting rod 402 can slide in a specific path in the annular groove 4032. When the first connecting rod 402 slides reversely, the steps of the stepped surface 40322 with a larger distance from the first surface 4031 will hinder it.

[0090] It should be noted that the above arrangement of the stepped surfaces 40322 can be clockwise or counterclockwise, and the present application does not limit this.

[0091] Thus, the present application can prevent the first link 402 from sliding in any direction during the sliding process, ensuring that the first link 402 can slide in a specific direction. The stability of the sliding between the hook 700 and the fixing member 400 in the present application is further improved.

[0092] Further, when the resilient member 600 is in its initial state, that is, when the baffle 300 closes the air suction port 101, the resilient member 600 is compressed by the slider 403, and the direction of deformation of the resilient member 600 is parallel to the sliding direction of the baffle 300. Alternatively, the resilient member 600 is in its original factory state.

[0093] In this way, when the user needs to pull the baffle 300, the user only needs to press the baffle 300. The baffle 300 drives the slider 403 to compress the resilient member 600. The resilient member 600 generates a force on the slider 403, and the slider 403 generates a force on the baffle 300, thereby pushing the baffle 300 away from the housing 100. Through the above settings, the user can easily pull the baffle 300 out of the housing 100 by using the protruding part of the baffle 300. Thus, the present application improves the user experience.

[0094] Exemplarily, the resilient member 600 can be a spring or a rubber pad, and the present application does not limit this.

[0095] Among them, the principle of spring resilience is based on Hooke's law. Hooke's law means that when the spring is not deformed or slightly deformed, the elastic force exerted on the spring is proportional to the degree of deformation. When an external force acts on the spring, the spring will deform and store elastic potential energy. Once the external force stops acting or decreases, the spring will release the previously stored elastic potential energy, causing the spring to return to its original state and rebound.

[0096] In some embodiments, the range hood in the present application further includes a sliding member 500. The sliding member 500 is connected to the rod body 701. The slider 403 is formed with a sliding groove 4033. The sliding member 500 is slidably connected to the sliding groove 4033, and the sliding member 500 can drive the hook 700 to rotate during the sliding process.

[0097] Exemplarily, referring to Figure 13 and Figure 14 , the sliding member 500 can be a cam or a pulley, and the present application does not limit this.

[0098] Specifically, referring to Figure 7 , when the sliding member 500 is a pulley, the pulley is rotatably connected to the first connecting portion 7011. The fixed housing 401 is provided with a fixed column 402. The pulley is rotatably connected to the fixed column 402 provided on the fixed housing 401. The sliding member 500 will generate a force on the first connecting portion 7011 during the sliding process in the sliding groove 4033.

[0099] However, since the fixed column 402 limits the movement of the pulley, the pulley can only rotate, and thus, the first connecting portion 7011 can only rotate, driving the engaging portion 702 to lock or disengage from the engaging member 800.

[0100] In some embodiments, referring to Figure 13 、 Figure 14 and in combination with Figure 7 In the present application, the rod body 701 includes a first connecting portion 7011 and a second connecting portion 7012. One end of the first connecting portion 7011 is rotatably connected to the fixed housing 401, and the other end of the first connecting portion 7011 is connected to the engaging portion 702. One end of the second connecting portion 7012 is connected to the first connecting portion 7011. The second connecting portion 7012 is located on the side of the first connecting portion 7011 close to the fixing member 400, and the other end of the second connecting portion 7012 is connected to the sliding member 500.

[0101] In this way, by the rotation of the second connecting portion 7012, the buckling and disengagement between the rod body 701 and the engaging member 800 can be realized, so that the baffle 300 can be fixed or slid.

[0102] Referring to Figure 13 When the sliding member 500 is a cam, when the cam rotates, it can abut against the rod body 701, thereby driving the rod body 701 to rotate.

[0103] In some embodiments, continuing to refer to Figure 7 the fixing member 400 further includes a second connecting rod 900. One end of the second connecting rod 900 is connected to the slider 403. When the baffle 300 closes the air inlet 101, the other end of the second connecting rod 900 contacts the baffle 300.

[0104] By providing the second connecting rod 900, the baffle 300 can drive the hook 700 to slide when quickly closing the air inlet 101, providing an installation space and a buckling stroke for the buckling between the baffle 300 and the hook 700.
