Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a range hood. Background Technology

[0002] Existing integrated range hood and cooktop units typically house the fume extraction unit inside the cabinet, with the air intake directly on the countertop. When the cooktop is in use, the fume extraction unit draws in cooking fumes directly through the intake, significantly reducing the vertical space occupied by the unit. However, in cases of heavy cooking, fumes further from the intake can escape, resulting in poor fume extraction and reduced air quality in the kitchen. Furthermore, the addition of an air intake on the countertop divides the countertop space, limiting the size of the cooktop. Utility Model Content

[0014] The embodiments of this application have the following advantages: The range hood provided by this application connects the air inlet component to the pop-up release mechanism. In the first state, the pop-up release mechanism pushes the air inlet component out of the installation channel through its telescopic end, causing at least part of the air inlet component to protrude along the first direction from the side of the main body away from the guide device. This allows the fan to generate negative pressure around the air inlet component during operation, enabling the flue gas outside the air inlet component to enter the guide channel through the air inlet component under the action of negative pressure and be discharged from the exhaust end of the guide channel. This not only increases the exhaust volume but also improves the efficiency of collecting and discharging oil fumes. In addition, when the pop-up release mechanism is in the second state, the air inlet component is completely housed in the installation channel. At this time, the air inlet component is in a retracted state, meaning that the range hood stops operating to ensure the flatness and aesthetics of the side of the main body away from the guide device. Pressing the air inlet component with external force switches the pop-up release mechanism between the first and second states, thereby causing the air inlet component to rise or fall along the first direction, improving the user experience and ease of use.

[0025] like Figures 1 to 10 The present application provides a range hood with a first direction Z, which is mainly used to improve the efficiency and convenience of exhausting oil fumes.

[0026] The range hood includes a main body 100, a flow guiding device 200, and a flow guiding component 300.

[0027] The main body 100 is provided with an installation channel 110 that extends through the first direction Z. In some embodiments, the installation channel 110 is located in the middle of the main body 100.

[0028] It should be noted that the main body 100 includes at least one of an induction cooker or an electric ceramic cooker.

[0029] In this embodiment, the induction cooker has a first heating zone and a second heating zone, and the mounting channel 110 is located between the first heating zone and the second heating zone.

[0030] A flow guiding device 200 is disposed on one side of the main body 100 along the first direction Z. The flow guiding device 200 includes a fan 210 and a housing 220. The housing 220 is connected to the main body 100 and defines a flow guiding channel 230 communicating with the mounting channel 110. The fan 210 is disposed in the flow guiding channel 230. The air inlet end of the fan 210 is close to the air inlet end of the mounting channel 110, and the air outlet end of the fan 210 is close to the air outlet end of the mounting channel 110. This allows external flue gas to enter the flow guiding channel 230 through the air inlet ends of the mounting channel 110 and the flow guiding channel 230 when the fan 210 is running, and to be discharged from the exhaust end of the flow guiding channel 230, thereby improving the smoke trapping efficiency.

[0031] The airflow guide assembly 300 is disposed in the mounting channel 110 and connected to the housing 220. In this embodiment, the airflow guide assembly 300 and the housing 220 are connected in a detachable manner, which not only improves the assembly efficiency between the airflow guide assembly 300 and the housing 220, but also facilitates the removal of the airflow guide assembly 300 from the housing 220 for maintenance, cleaning, or replacement. Furthermore, the airflow guide assembly 300 includes an air inlet 310 and a spring-loaded opening device 320. The spring-loaded opening device 320 is connected to the housing 220, and the connection method between the spring-loaded opening device 320 and the housing 220 includes any one of bolt connection, snap-fit, adhesive, or magnetic connection.

[0032] In this embodiment, the air inlet 310 is slidably connected to the main body 100 along the first direction Z, and the air inlet 310 is connected to the guide channel 230. The air inlet 310 is connected to the telescopic end of the pop-up device 320. The pop-up device 320 has a first state and a second state under the pressure along the first direction Z.

[0033] Specifically, such as Figure 2As shown, in the first state, the telescopic end of the pop-up device 320 is in an extended state, and the telescopic end of the pop-up device 320 pushes the air inlet 310 out of the installation channel 110, so that the air inlet 310 protrudes at least partially along the first direction Z from the side of the main body 100 away from the guide device 200. This allows the fan 210 to form a negative pressure around the air inlet 310 when it is running, so that the flue gas outside the air inlet 310 can enter the guide channel 230 through the air inlet 310 under the action of the negative pressure and be discharged from the exhaust end of the guide channel 230. This not only increases the exhaust volume, but also improves the collection and emission efficiency of oil fumes.

[0034] In addition, such as Figure 1 As shown, when the pop-up device 320 is in the second state, the air inlet 310 is fully housed in the installation channel 110. At this time, the air inlet 310 is in a retracted state, which means that the range hood stops operating to ensure the flatness and aesthetics of the side of the main body 100 away from the air guide device 200, thereby improving the user experience and ease of use.

[0035] It is understood that by applying pressure along the first direction Z to the air inlet 310, the pop-up device 320 can switch between the first state and the second state. Thus, the pop-up device 320 drives the air inlet 310 to slide along the first direction Z in the installation channel 110. This not only improves the convenience of using the range hood and stove, but also increases the exhaust volume, reduces noise, and improves exhaust efficiency by introducing air around the air inlet 310.

[0036] In this application, the position of the air inlet 310 when the pop-up device 320 is in the first state is defined as the extended position, and the position of the air inlet 310 when the pop-up device 320 is in the second state is defined as the retracted position.

[0037] It is understandable that when the spring-loaded device 320 switches between the first and second states under the action of external force, it drives the air intake component 310 to switch between the extended and retracted positions.

[0038] It should be noted that, in this embodiment, "the spring opener 320 under the action of external force" means that after the air inlet 310 receives the action of external force, the external force is transmitted to the spring opener 320 through the air inlet 310.

[0039] like Figure 4As shown, in some embodiments of this application, the range hood has a second direction Y and a third direction X that are mutually perpendicular to the first direction Z. The flow guiding assembly 300 includes a housing 330, which is housed in the installation channel 110 and connected to the outer shell 220. The housing 330 has a first ventilation section 331 communicating with the flow guiding channel 230 on at least one side along the second direction Y.

[0040] In this embodiment, the housing 330 is provided with first ventilation sections 331 communicating with the guide channel 230 on both sides along the second direction Y. The air inlet 310 is slidably connected to the housing 330 along the first direction Z. The air inlet 310 is connected to the first ventilation section 331 so that the oil fumes flowing through the air inlet 310 can enter the guide channel 230 through the first ventilation section 331. By increasing the number of first ventilation sections 331, the exhaust volume and exhaust efficiency of the housing 330 are improved, and the noise is reduced.

[0041] like Figure 4 As shown, in some embodiments of this application, the housing 330 has a bottom wall 332 facing the air inlet 310 along the first direction Z, the pop-up device 320 is disposed between the bottom wall 332 and the air inlet 310, and the air inlet 310 is provided with the pop-up device 320 at both ends along the third direction X, so as to improve the stability of the air inlet 310 during the movement along the first direction Z.

[0042] like Figure 2 As shown, in some embodiments of this application, the spring-loaded device 320 includes a fixing member 321, a sliding member 322, a first elastic member 323, and a limiting member 324. The fixing member 321 defines a groove 3211 along the first direction Z. The fixing member 321 is slidably disposed in the groove 3211 along the first direction Z so as to provide guidance and limiting effect on the sliding member 322 along the first direction Z through the groove wall of the groove 3211, thereby ensuring the stability of the sliding member 322 during the sliding process along the first direction Z. The sliding member 322 is provided with a limiting groove 3221 on one side along the second direction Y.

[0043] The limiting member 324 has a first connecting end 3241 and a second connecting end 3242. The first connecting end 3241 is connected to the fixing member 321, and the second connecting end 3242 is slidably disposed in the limiting groove 3221. The first elastic member 323 is received in the sliding groove 3211. It should be noted that the limiting member 324 has a certain elasticity, can undergo elastic deformation under the action of external force, and can return to its original shape after the external force is removed.

[0044] It should be noted that the second connecting end 3242 can slide along the slide groove 3211, and the inner wall of the slide groove 3211 guides and limits the second connecting end 3242 during the sliding process, so as to ensure that the pop-up device 320 can switch between the first state and the second state.

[0045] In this embodiment, one end of the first elastic member 323 is connected to the side of the slide groove 3211 facing the slider 322 along the first direction Z, and the other end of the first elastic member 323 is connected to the slider 322. It should be noted that the first elastic member 323 is in a compressed state between the slider 322 and the fixing member 321; that is, the first elastic member 323 always exerts a spring force on the slider 322 along the first direction Z in a direction away from the fixing member 321.

[0046] like Figures 6 to 9 As shown, in some embodiments of this application, the limiting groove 3221 includes a first groove 32211, a first limiting groove 32212, and a guide groove 32213 that are connected to each other.

[0047] The guide groove 32213 has a groove bottom arranged along the second direction Y. The groove bottom is provided with a guide member 325. The guide member 325 divides the first guide groove 322131 into a connected first guide groove 322131 and a second guide groove 322132. The first guide groove 322131 and the second guide groove 322132 are distributed along the second direction Y.

[0048] In this embodiment, the first limiting groove 32212 is provided with a guide protrusion 3224 on one side along the third direction X. The guide protrusion 3224 protrudes along the third direction X towards the first positioning part 326, so as to provide guidance and limiting for the second connecting end 3242 through the guide protrusion 3224, so as to ensure that during the process of the pop-up device 320 switching from the first state to the second state, the sliding path of the second connecting end 3242 in the limiting groove 3221 passes through the first groove 32211, the first limiting groove 32212 and the first guide groove 322131 in sequence; at the same time, it is ensured that during the process of the pop-up device 320 switching from the second state to the first state, the sliding path of the second connecting end 3242 in the limiting groove 3221 passes through the first guide groove 322131, the second guide groove 322132, the first limiting groove 32212 and the first groove 32211 in sequence.

[0049] Furthermore, the guide member 325 has intersecting fourth inclined surface 3251 and fifth inclined surface 3252 on the side facing the limiting member 324 along the first direction Z. The fourth inclined surface 3251 is arranged along the third direction X towards the first guide groove 322131, so that when the pop-up device 320 switches from the first state to the second state, the fourth inclined surface 3251 provides a guiding effect on the second connecting end 3242 to ensure that the second connecting end 3242 can slide in the first guide groove 322131. Secondly, the fifth inclined surface is arranged along the third direction X towards the second guide groove 322132, so that when the pop-up device 320 switches from the second state to the first state, the fifth inclined surface 3252 provides a guiding effect on the second connecting end 3242 to ensure that the second connecting end 3242 can slide in the first guide groove 322131.

[0050] In this embodiment, the guide protrusion completely covers the fifth inclined surface 3252 along the first direction Z, and the guide protrusion partially covers the fourth inclined surface 3251 along the first direction Z. This allows the second connecting end 3242 to be guided by the guide protrusion during the process of the pop-up device 320 switching from the first state to the second state. This ensures that the second connecting end 3242 can contact the fourth inclined surface 3251 under the guidance of the guide protrusion, and that the second connecting end 3242 is guided into the first guide groove 322131 by the fourth inclined surface 3251. This ensures that the pop-up device 320 can switch to the first state accurately.

[0051] like Figure 6 As shown, in some embodiments of this application, the guide groove 32213 is provided with a first positioning part 326, a first inclined surface 327 and a second positioning part 328 on the side of the guide member 325 along the first direction Z, wherein the first inclined surface 327 is located between the first positioning part 326 and the second positioning part 328 along the third direction X.

[0052] The guide member 325 has an intersecting second inclined surface 3254 and a third inclined surface 3255 on the side facing the first inclined surface 327. The included angle between the first inclined surface 327 and the second inclined surface 3254 is smaller than the included angle between the first inclined surface 327 and the third inclined surface 3255, so that the second inclined surface 3254 and the third inclined surface 3255 are connected to form a recessed portion. The recessed portion is recessed in the first direction Z in a direction away from the first inclined surface 327, so that the second inclined surface 3254 and the third inclined surface 3255 can provide a limiting effect on the second connecting end 3242 to ensure the stability of the second connecting end 3242 in the recessed portion, thereby ensuring the stability of the spring opener 320 in the second state.

[0053] Along the first direction Z, the second inclined surface 3254 completely covers the first positioning part 326, so that after the second connecting end 3242 passes through the first guide groove 322131, it can connect with the first positioning part 326, so that the first positioning part 326 provides a limiting and positioning function for the second connecting end 3242. After the external force acting on the spring opener 320 is removed, the sliding member 322 can be pushed along the first direction Z towards the side away from the fixing member 321 under the elastic force of the first elastic member 323, so that the second connecting end 3242 can be directly opposite the second inclined surface 3254 along the first direction Z under the guidance of the first positioning part 326. 254, so that the second connecting end 3242 is guided to the recess formed between the second inclined surface 3254 and the third inclined surface 3255 by the second inclined surface 3254, thereby providing a limiting effect on the second connecting end 3242 by the second inclined surface 3254 and the third inclined surface 3255, thereby ensuring the stability of the second connecting end 3242 between the second inclined surface 3254 and the third inclined surface 3255, thereby improving the accuracy, stability and convenience of the pop-up device 320 switching to the second state, thereby ensuring the stability of the air inlet 310 during the sliding process along the first direction Z in the installation channel 110, and improving the convenience and stability of the air inlet 310 extending out of the installation channel 110.

[0054] In this embodiment, the first inclined surface 327 and the second inclined surface 3254 at least partially overlap, the first inclined surface 327 completely covers the third inclined surface 3255, and the second positioning part 328 is offset from the third inclined surface 3255 along the third direction X, so that during the process of the pop-up device 320 switching from the second state to the first state, the sliding member 322 moves towards the fixing member 321 under the pressure along the first direction Z. At this time, the second connecting end 3242 separates from the second inclined surface 3254 and the third inclined surface 3255. At the same time, the second connecting end 3242 abuts against the first inclined surface 327, and the first inclined surface 327 provides guidance for the second connecting end 3242. The function is to allow the second connecting end 3242 to slide to the second positioning part 328 under the guidance of the first inclined surface 327, and the second positioning part 328 provides a positioning function for the second connecting end 3242. When the external force acting on the spring release 320 is removed, the sliding member 322 moves away from the fixing member 321 in the first direction Z under the elastic force of the spring. At the same time, the second connecting end 3242 enters the second guide groove 322132 under the guidance and limiting function of the second positioning part 328, and then enters the first groove 32211 after passing through the fifth inclined surface 3252 guide protrusion and the first limiting groove 32212 in sequence, thereby switching the spring release 320 from the second state to the first state.

[0055] like Figures 6 to 8As shown, in some embodiments of this application, the second connecting end 3242 is offset along the third direction X towards the second positioning part 328 to ensure that when the pop-up device 320 switches from the second state to the first state, the limiting member 324 undergoes elastic deformation when the second connecting end 3242 abuts against the fourth inclined surface 3251, and the second connecting end 3242 has a tendency to move along the third direction X towards the fifth inclined surface 3252, so as to ensure that when the second connecting end 3242 passes through the first guide groove 322131, the second connecting end 3242 can swing along the third direction X towards the second guide groove 322132 under the elastic force of the limiting member 324, thereby ensuring the smoothness and stability of the pop-up device 320 switching from the second state to the first state or from the second state to the first state, thereby ensuring the smoothness and stability of the air inlet 310 during the process of rising or falling along the first direction Z in the installation channel 110.

[0056] like Figure 6 As shown, in some embodiments of this application, the first positioning part 326 is adjacent to the first guide groove 322131, so that when the pop-up device 320 switches from the second state to the first state, the first positioning part 326 provides positioning and guiding function for the second connecting end 3242, so as to ensure that the pop-up device 320 can switch from the second state to the first state accurately.

[0057] In addition, the second positioning part 328 is adjacent to the second guide groove 322132 so that when the pop-up device 320 switches from the first state to the second state, the second positioning part 328 provides positioning and guidance for the second connecting end 3242, so as to ensure that the pop-up device 320 can switch from the first state to the second state accurately and without error, thereby ensuring the smoothness and accuracy of the air inlet 310 switching between the extended position and the retracted position.

[0058] like Figure 6 As shown, in some embodiments of this application, when the spring-loaded device 320 is in the first state, the second connecting end 3242 is located in the first groove 32211 and abuts against the side of the first groove 32211 facing the guide protrusion 3224 along the first direction Z. When the spring-loaded device 320 is in the second state, the second connecting end 3242 is located between the second inclined surface 3254 and the third inclined surface 3255, so that the second connecting end 3242 is limited along the first direction Z by the second inclined surface 3254 and the third inclined surface 3255, so as to ensure the stability of the spring-loaded device 320 in the second state, thereby ensuring the stability of the air inlet 310 in the retracted position.

[0059] like Figures 7 to 9As shown, in some embodiments of this application, the fixing member 321 has a limiting plate 3212 disposed away from the sliding member 322 along the first direction Z. The sliding groove 3211 is provided with a limiting post 329. The axial direction of the limiting post 329 is parallel to the third direction X, and the side wall of the limiting post 329 is spaced apart from the inner wall of the sliding groove 3211. The limiting post 329 is connected to the limiting plate 3212. The first elastic member 323 is sleeved on the limiting post 329 to provide guidance and limiting for the first elastic member 323 through the limiting post 329, so as to ensure the stability of the first elastic member 323 during the process of elongation or contraction along the first direction Z.

[0060] The limiting post 329 has a limiting ring 3291 at one end near the limiting plate 3212, and the sliding member 322 has a third guide groove 3222 along the first direction Z. The limiting post 329 and the first elastic member 323 are respectively at least partially housed in the third guide groove 3222, so as to provide limiting and guiding function for the first elastic member 323 through the third guide groove 3222. At the same time, the inner wall of the limiting post 329 and the third guide groove 3222 forms a limiting and guiding function for the sliding member 322 along the first direction Z, so as to ensure the stability and smoothness of the sliding member 322 during the sliding process along the first direction Z.

[0061] In addition, one end of the first elastic member 323 abuts against the limiting ring 3291, and the other end of the first elastic member 323 abuts against the side of the third guide groove 3222 facing the limiting ring 3291. That is, the first elastic member 323 is always in a compressed state, thereby ensuring the smooth switching of the pop-out device 320 between the first state and the second state.

[0062] like Figure 7 As shown, in some embodiments of this application, the slide groove 3211 is provided with a limiting platform 3213 on the side away from the limiting member 324 along the second direction Y. The limiting platform 3213 is provided close to the limiting member 324 along the first direction Z. The sliding member 322 is provided with a limiting part 3223 on the side facing the limiting platform 3213 along the second direction Y. When the pop-out device 320 is in the first state, the limiting part 3223 abuts against the limiting platform 3213, thereby limiting the limiting part 3223 in the first direction Z through the limiting platform 3213, so as to prevent the sliding member 322 from sliding out of the slide groove 3211.

[0063] like Figure 4 and Figure 5As shown in some embodiments of this application, the flow guiding component 300 further includes a buffer 340 and a connector 350. The buffer 340 is provided with a fourth guide groove 341 on the side facing the air inlet 310 along the first direction Z. The fourth guide groove 341 has two first groove walls 342 arranged opposite to each other along the third direction X. The first groove walls 342 are provided with mounting holes 343 through the third direction X. It should be noted that the number of mounting holes 343 can be one, two or more, and can be specifically set according to the actual situation.

[0064] In some embodiments, the first groove wall 342 is provided with a plurality of mounting holes 343 through the third direction X, and the plurality of mounting holes 343 are arranged at equal intervals along the first direction Z.

[0065] The mounting hole 343 is provided with a second elastic element 344 and a ball 345. The ball 345 is at least partially received in the mounting hole 343 and is located on the side of the second elastic element 344 facing the fourth guide groove 341.

[0066] In this embodiment, the distance between the two first sidewalls along the third direction X is less than the outer diameter of the ball 345 to prevent the ball 345 from falling out of the fourth guide groove 341, thereby ensuring the stability of the ball 345 in the mounting hole 343. Additionally, it should be noted that the second elastic member 344 is always in a compressed state in the mounting hole 343, so that the second elastic member 344 always exerts an elastic force on the ball 345 along the third direction X.

[0067] In addition, one end of the connector 350 along the first direction Z is slidably connected to the groove wall of the fourth guide groove 341, and the other end of the connector 350 along the first direction Z is connected to the air inlet 310, so that when the air inlet 310 moves along the first direction Z, it can drive the connector 350 to slide along the first direction Z in the fourth guide groove 341.

[0068] In this embodiment, the connector 350 has a plurality of clearance grooves 351 on the side facing the first groove wall 342. The ball bearing 345 can be engaged in the clearance groove 351 to form an elastic limiting structure by connecting the ball bearing 345 with the groove wall of the clearance groove 351. This adjusts the distance between the end of the connector 350 near the air inlet 310 along the first direction Z and the bottom of the groove, thereby adjusting the distance between the side of the air inlet 310 facing the bottom of the groove and the bottom of the groove. In other words, it adjusts the position or height of the air inlet 310 relative to the main body 100 along the first direction Z to meet the user's needs and improve the user experience.

[0069] like Figure 4 and Figure 10As shown, in some embodiments of this application, the housing 330 is provided with a filter assembly 400 on the side facing the spring-loaded device 320 assembly along the second direction Y. The filter assembly 400 covers the first ventilation section 331 along the second direction Y, and the filter assembly 400 has a gap with the air inlet 310.

[0070] The connection between the filter assembly 400 and the housing 330 can be any one of magnetic connection, threaded connection, bolt connection, snap-fit, adhesive connection or tenon and mortise connection. In other words, this application makes the filter assembly 400 and the housing 330 detachably connected, which not only ensures the stability of the connection between the filter assembly 400 and the housing 330, but also improves the convenience of installing or removing the filter assembly 400 and the housing 330, so as to facilitate the maintenance, cleaning or replacement of the filter assembly 400, thereby ensuring the filtration quality and filtration effect of the range hood on the oil fumes.

[0071] like Figure 3 , Figure 4 and Figure 10 As shown in some embodiments of this application, the air inlet 310 is provided with a first air inlet 311 on the side opposite to the flow guide device 200 along the first direction Z, and the air inlet 310 is provided with a second air inlet 312 on two opposite sides along the second direction Y, which communicates with the first air inlet 311. The first air inlet 311 and the second air inlet 312 are respectively connected to the first ventilation section 331. By providing multiple air inlets on the air inlet 310, the fumes can enter the air inlet 310 from the first air inlet 311 and the second air inlet 312 at the same time, and enter the flow guide channel 230 through the first ventilation section 331, so as to increase the air intake and exhaust volume of the stove, which can not only reduce noise, but also improve the smoke containment efficiency.
