[0003] The present application aims to solve one of the technical problems in the related art at least to a certain extent. To this end, the present application proposes a desktop range hood.

[0004] To achieve the above-mentioned purpose, the present application discloses a desktop range hood, which comprises:

[0005] An air duct housing having an air outlet; and

[0006] The protective cover is arranged at the air outlet and occupies a part of the area of ​​the air outlet.

[0012] In some embodiments of the present application, at least a portion of the protective cover is embedded in the air duct shell, and is projected along the axial direction of the air outlet. The projection of the protective cover is located within the range of the projection of the air outlet, and the projection of the flow space is located between the edge of the projection of the protective cover and the edge of the projection of the air outlet.

[0013] In some embodiments of the present application, the desktop range hood further comprises a bracket, the bracket is arranged in the air duct housing, and the protective cover is connected to the bracket.

[0043] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0045] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0046] In addition, in this application, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0047] This application proposes a desktop range hood, combined with Figures 1 to 8 As shown, in some embodiments, the desktop range hood includes an air duct shell 1100 and a protective cover 3000 , the air duct shell 1100 is provided with an air outlet 1500 , the protective cover 3000 is arranged at the air outlet 1500 and occupies a partial area of ​​the air outlet 1500 .

[0048] By setting the protective cover 3000 at the air outlet 1500, the protective cover 3000 occupies a part of the area of ​​the air outlet 1500. When the oil smoke is discharged from the air outlet 1500, it encounters the obstruction of the protective cover 3000. A part of the oil smoke needs to change direction when encountering the obstruction of the protective cover 3000 before it can continue to be discharged. Such a setting has a buffering effect on the discharge of oil smoke, reducing the flow rate of the user directly blown (blowing along the axial direction of the air outlet 1500). It is precisely because the protective cover 3000 occupies a part of the area of ​​the air outlet 1500 that the contact area of ​​the oil smoke with the user is reduced when it is discharged. Such a setting weakens the discomfort caused by the oil smoke blowing to the user, thereby improving the user experience.

[0049] Specifically, the tabletop range hood includes a body 2000 and a range hood body 1000 installed on the body 2000. The tabletop range hood is placed on a tabletop through the body 2000, so that the range hood body 1000 is a certain distance away from the tabletop. The range hood body 1000 includes an air duct shell 1100 and a fan 1200. The air duct shell 1100 is surrounded by an air duct 1300. One end of the air duct 1300 constitutes an air inlet 1400, and the other end of the air duct 1300 constitutes an air outlet 1500. The fan 1200 is arranged in the air duct 1300 and is located between the air inlet 1400 and the air outlet 1500. When the fan 1200 is working, it can drive the oil smoke from the air inlet 1400 into the air duct 1300 and be discharged from the air outlet 1500.

[0050] The air duct housing 1100 is basically a cylindrical structure, the air inlet 1400 is open along the axial direction of the air duct housing 1100, and the air outlet 1500 is also open along the axial direction of the air duct housing 1100. The axial direction of the air duct housing 1100 here can be understood as the extension direction of the rotation axis of the fan 1200 (i.e. Figure 1 in the front-to-back direction).

[0051] When in use, the tabletop range hood needs to be placed on the table and the range hood body 1000 is placed close to the smoke source. In some usage scenarios, such as hot pot, the tabletop range hood is placed on the dining table and close to the hot pot body. When the tabletop range hood is working, it can suck the oil smoke from the pot body and discharge it in a specific direction. If there are many users, the users sit around the dining table, and some users sit facing the air outlet 1500, the exhaust smoke of the tabletop range hood will blow towards these users.

[0052] For this purpose, in this embodiment, a protective cover 3000 is provided, and the protective cover 3000 is provided at the air outlet 1500, so that the protective cover 3000 occupies part of the area of ​​the air outlet 1500. When the oil smoke is discharged from the air outlet 1500, a part of the oil smoke will be discharged from the position of the air outlet 1500 not occupied by the protective cover 3000, and a part of the oil smoke will be blocked by the protective cover 3000 and then change direction, and then be discharged from the position of the air outlet 1500 not occupied by the protective cover 3000. Since a part of the oil smoke changes direction when encountering resistance, a buffering effect is played on the flow of the oil smoke. In particular, the protective cover 3000 can be designed to be substantially perpendicular to the flow direction of the oil smoke, and the oil smoke collides with the protective cover 3000 in a direction substantially perpendicular to the protective cover 3000 and then changes direction, so that a better buffering effect can be formed on the oil smoke. In addition, by providing the protective cover 3000, the area of ​​the air outlet 1500 becomes smaller, and when the oil smoke is discharged from the air outlet 1500 until it contacts the user, the contact area between the oil smoke and the user also becomes smaller, thereby reducing the range of the oil smoke blowing toward the user. By such a configuration, the discomfort caused by the oil smoke blowing toward the user is reduced as much as possible, and the user experience is improved.

[0053] It is understandable that the protective cover 3000 is located downstream of the fan 1200. By setting the protective cover 3000 at the air outlet 1500, the protective cover 3000 can also play a certain blocking role against the outside world, preventing the user from contacting the internal structure of the range hood body 1000 (such as the fan 1200), thereby improving the safety of use.

[0054] Combination Figures 5 to 9 As shown, in some embodiments, the protective cover 3000 is used to prevent the oil smoke from being discharged from the edge range of the protective cover 3000, and the protective cover 3000 is designed to have a flow space 3300 between it and the edge of the air outlet 1500.

[0055] For example, the air outlet 1500 is divided into a first area 1510 and a second area 1520, the first area 1510 is closer to the center of the air outlet 1500 than the second area 1520, and the second area 1520 surrounds the first area 1510. When the protective cover 3000 is set in the first area 1510, the second area 1520 is located between the protective cover 3000 and the edge of the air outlet 1500, that is, at least part of the second area 1520 forms a flow space 3300.

[0056] When the oil smoke is discharged from the air outlet 1500, part of the oil smoke will be discharged from between the protective cover 3000 and the edge of the air outlet 1500 (flow space 3300), and part of the oil smoke will be blocked by the protective cover 3000 and then changed direction and then discharged from between the protective cover 3000 and the edge of the air outlet 1500 (flow space 3300). Generally speaking, the amount of oil smoke near the center of the air outlet 1500 (first area 1510) is greater. By setting the protective cover 3000 in the first area 1510 and blocking the oil smoke, the oil smoke is blocked from being discharged from the first area 1510, further improving the buffering effect of the oil smoke.

[0057] In some embodiments, the protective cover 3000 occupies 70% to 85% of the area of ​​the air outlet 1500, which may be 70%, 75%, 80% or 85%. The following method can be used for measurement: for example, when projecting along the axial direction of the air outlet 1500 toward a plane (the plane is perpendicular to the axial direction of the air outlet 1500), the projected area of ​​the protective cover 3000 is 70% to 85% of the projected area of ​​the air outlet 1500, thereby further optimizing the performance.

[0058] As described above, the protective cover 3000 is set so that the oil smoke cannot be discharged from the edge of the protective cover 3000. However, the blocking of a large amount of oil smoke by the protective cover 3000 will generate noise to a certain extent, and it is necessary to avoid a significant increase in noise as much as possible. Figures 13 to 15As shown, in some embodiments, the protective cover 3000 is configured to have a flow space 3300 between the edge of the air outlet 1500 , and the protective cover 3000 is provided with an air outlet hole 3100 , which is connected to the air outlet 1500 .

[0059] For example, the air outlet 1500 is divided into a first area 1510 and a second area 1520. The first area 1510 is closer to the center of the air outlet 1500 than the second area 1520, and the second area 1520 surrounds the first area 1510. When the protective cover 3000 is arranged in the first area 1510, the second area 1520 is located between the protective cover 3000 and the edge of the air outlet 1500, that is, at least part of the second area 1520 forms a flow space 3300. When the oil smoke is discharged from the air outlet 1500, part of the oil smoke will be discharged from the edge between the protective cover 3000 and the air outlet 1500 (flow space 3300), part of the oil smoke will be discharged through the air outlet 3100, and part of the oil smoke will be blocked by the protective cover 3000 and then changed direction and then discharged through the edge between the protective cover 3000 and the air outlet 1500 (flow space 3300) or the air outlet 3100. By setting the air outlet 3100 on the protective cover 3000, the obstruction to the oil smoke can be appropriately reduced (but there is still a certain obstruction, just lower than the obstruction that completely prevents the oil smoke from being discharged from the edge of the protective cover 3000), which is helpful to avoid a significant increase in noise.

[0060] In order to ensure that the discomfort caused by the oil smoke blowing toward the user can still be reduced when the air outlet 3100 is set, the protective cover 3000 includes a guide tongue 3200, which is set around the air outlet 3100, for example, the guide tongue 3200 is set at the edge of the air outlet 3100. When the oil smoke is discharged through the air outlet 3100, it will encounter the guide tongue 3200, and the guide tongue 3200 plays a guiding role for the oil smoke. In this embodiment, the guide tongue 3200 is designed to be inclined relative to the axial direction of the air outlet 1500. The direction of the guide tongue 3200 can be determined according to the actual survey situation, so as to minimize the oil smoke blowing directly (along the axial direction of the air outlet 1500) toward the user through the air outlet 3100. In addition, the oil smoke discharged from the air outlet 3100 intersects with the oil smoke discharged from the flow space 3300, and the two oil smokes intersect, which further plays a buffering effect.

[0061] Combination Fig.14 and Fig.16As shown, in some embodiments, the guide tongue 3200 includes a first guide tongue 3210, a second guide tongue 3220 and a third guide tongue 3230, wherein the first guide tongue 3210, the second guide tongue 3220 and the third guide tongue 3230 are designed to be arranged along the axial direction around the air outlet 1500, and the inclination direction of the first guide tongue 3210, the inclination direction of the second guide tongue 3220 and the inclination direction of the third guide tongue 3230 are designed to be divergent, and the inclination direction of each guide tongue 3200 is designed to be radiating, so that the oil smoke is dispersed along the circumference of the air outlet 1500 (in a diffused manner), reducing the amount of oil smoke in a certain direction. Even if there is oil smoke blowing towards the user through the air outlet 3100, the amount of oil smoke is greatly reduced.

[0062] For example Fig.16 In the orientation shown, the protective cover 3000 is divided into three parts, and the three parts are arranged in a circle. One part of the protective cover 3000 includes a first guide tongue 3210, another part of the protective cover 3000 includes a second guide tongue 3220, and the remaining part of the protective cover 3000 includes a third guide tongue 3230. The first guide tongue 3210 is inclined toward the upper left, the second guide tongue 3220 is inclined toward the right, and the third guide tongue 3230 is inclined toward the lower left, so that the inclination direction of each guide tongue 3200 is divergent (see Fig.16 of oil smoke).

[0063] Further, under the premise that the protective cover 3000 is provided with the air outlet 3100, the protective cover 3000 occupies 40% to 60% of the area of ​​the air outlet 1500, which can be 40%, 50%, 55% or 60%. The following method can be used for measurement: for example, along the axial direction of the air outlet 1500, a projection is made toward a plane (the plane is perpendicular to the axial direction of the air outlet 1500), and the area of ​​the projection of the protective cover 3000 is 40% to 60% of the area of ​​the projection of the air outlet 1500, so as to further optimize the performance.

[0064] Combination Figure 5 and Figure 6As shown, in some embodiments, at least part of the protective cover 3000 is embedded in the air duct housing 1100, and is projected along the axial direction of the air outlet 1500. The projection of the protective cover 3000 is located within the projection of the air outlet 1500, and the projection of the flow space 3300 is set between the edge of the projection of the air outlet 1500 and the edge of the projection of the protective cover 3000. In this way, the proportion of the protective cover 3000 in the user's field of vision can be minimized. It is understandable that when using the desktop range hood, the desktop range hood is placed on the desktop, and the user mainly sees the appearance of the air duct housing 1100. This embodiment improves the installation position of the protective cover 3000, so that the user is not easy to see the protective cover 3000 at more angles, thereby enhancing the sensory experience.

[0065] Combination Figure 3 and Figure 4 As shown, in some embodiments, the desktop range hood further includes a bracket 1600 (the bracket 1600 can be regarded as a part of the range hood body 1000 ), the bracket 1600 is disposed in the air duct housing 1100 , and the protective cover 3000 is connected to the bracket 1600 .

[0066] Specifically, the bracket 1600 is arranged inside the air duct shell 1100, and it is not easy for a user to observe the bracket 1600. The arrangement of the bracket 1600 serves as a supporting basis for the installation of the protective cover 3000. Since the bracket 1600 is arranged inside the air duct shell 1100, when the protective cover 3000 is connected to the bracket 1600, the connection structure between the protective cover 3000 and the bracket 1600 can be hidden to a certain extent, which is not easy for a user to observe.

[0067] For example, the bracket 1600 is disposed in the air duct 1300 and is located between the air inlet 1400 and the air outlet 1500. The bracket 1600 may be a separate component connected and fixed to the air duct housing 1100 by a connection means, or the bracket 1600 and the air duct housing 1100 are an integrally formed structure, and the protective cover 3000 is connected to the bracket 1600 and at least part of it is embedded in the air duct housing 1100. There are many ways to connect the protective cover 3000 and the bracket 1600, as long as the protective cover 3000 is fixed, for example, by a snap connection, a screw connection, a magnetic connection, and other methods.

[0068] As mentioned above, the range hood body 1000 includes a fan 1200, which is a power source for sucking and exhausting oil smoke. The fan 1200 needs to be arranged inside the air duct shell 1100. In some embodiments, Figure 3 and Figure 4As shown, the bracket 1600 also serves as a supporting base for the fan 1200 , and the fan 1200 is connected and fixed to the bracket 1600 . In this way, the fan 1200 and the protective cover 3000 share the bracket 1600 , thereby reducing the number of brackets 1600 and simplifying the structure.

[0069] Furthermore, in some embodiments, the protective cover 3000 and the bracket 1600 are designed to be detachably connected, that is, when the protective cover 3000 is needed, the protective cover 3000 is connected and fixed to the bracket 1600, and when the protective cover 3000 is not needed, the protective cover 3000 can be removed. For example, in some application scenarios, it is not necessary to have a buffering effect on the emission of oil smoke, in which case the protective cover 3000 can be removed, while in other application scenarios, it is necessary to have a buffering effect on the emission of oil smoke, in which case the protective cover 3000 can be connected and fixed to the bracket 1600. There are many ways of detachable connection, such as snap connection, screw connection or magnetic connection, etc., and the detachable connection facilitates the disassembly and assembly between the protective cover 3000 and the bracket 1600.

[0070] Combination Fig.12 As shown, in some embodiments, the inner side of the protective cover 3000 includes a first annular wall 3001 (the inner side is the side facing the bracket 1600 ), the first annular wall 3001 protrudes toward the bracket 1600 , and the protective cover 3000 is connected to the bracket 1600 through the first annular wall 3001 .

[0071] Specifically, the first annular wall 3001 is disposed on the inner side of the protective cover 3000. When the protective cover 3000 is installed, the protective cover 3000 is fixed by the connection between the first annular wall 3001 and the bracket 1600. By providing the first annular wall 3001, the bracket 1600 can be kept away from the air outlet 1500 to a certain extent. In particular, when the fan 1200 is connected and fixed to the bracket 1600, the fan 1200 is not easily visible to the user, thereby minimizing the exposure of the fan 1200 to the user's field of vision.

[0072] It can be understood that by setting the first annular wall 3001 on the inner side of the protective cover 3000, the first annular wall 3001 can also strengthen the protective cover 3000, and the protective cover 3000 is not easy to deform. In particular, the first annular wall 3001 is designed to be arranged alternately with the edge of the protective cover 3000, so that the structural strength of the protective cover 3000 within the range of the first annular wall 3001 and the part outside the range can be strengthened.

[0073] Combination Fig.10 and Fig.12As shown, in some embodiments, one of the first annular wall 3001 and the bracket 1600 is provided with a claw 3110, and the other of the first annular wall 3001 and the bracket 1600 is provided with a clamping hole 1610. The claw 3110 is clamped in the clamping hole 1610 to achieve a snap connection, which can realize the installation and fixation of the protective cover 3000, as well as the disassembly of the protective cover 3000.

[0074] The first annular wall 3001 may be provided with a claw 3110, and the corresponding bracket 1600 may be provided with a hole 1610; or the first annular wall 3001 may be provided with a hole 1610, and the corresponding bracket 1600 may be provided with a claw 3110; or the first annular wall 3001 may be provided with both the claw 3110 and the hole 1610, and the corresponding bracket 1600 may be provided with the hole 1610 and the claw 3110, the claw 3110 of the first annular wall 3001 and the hole 1610 of the bracket 1600 correspond to each other, and the hole 1610 of the first annular wall 3001 and the claw 3110 of the bracket 1600 correspond to each other.

[0075] Taking the example that the first annular wall 3001 is provided with a claw 3110 and the corresponding bracket 1600 is provided with a hole 1610, when installing the protective cover 3000, the protective cover 3000 basically moves along the axial direction of the air outlet 1500 toward the bracket 1600 until the claw 3110 is engaged with the hole 1610, so that the protective cover 3000 can be fixed.

[0076] When the first annular wall 3001 is provided with a claw 3110, since the claw 3110 is protruding toward the bracket 1600, by providing the first annular wall 3001, the first annular wall 3001 can provide a reinforcing support for the claw 3110, and can effectively prevent the claw 3110 from breaking. It is particularly suitable for the case where the first annular wall 3001 and the claw 3110 are formed simultaneously by integral injection molding of the protective cover 3000.

[0077] Continue to combine Fig.10 and Fig.12 As shown, in some embodiments, one of the first annular wall 3001 and the bracket 1600 is provided with a pin 3120, and the other of the first annular wall 3001 and the bracket 1600 is provided with a socket 1620. When the protective cover 3000 is installed in place, the pin 3120 is inserted into the socket 1620.

[0078] For example, the first ring wall 3001 is provided with a latch 3120 and the bracket 1600 is provided with a socket 1620. Through the cooperation between the latch 3120 and the socket 1620, the alignment of the claw 3110 and the hole 1610 is ensured, and the claw 3110 can be evenly stressed, thereby ensuring the reliability of the connection.

[0079] Combination Figure 3 , Figure 4 , Figure 7 , Figure 8 , Fig.11 and Fig.12 As shown, in some embodiments, the air duct shell 1100 includes a connecting platform 1700, and the connecting platform 1700 is provided with a limiting groove 1710, and the protective cover 3000 includes a limiting portion 3002, and the limiting portion 3002 is protruded relative to the edge of the protective cover along the radial direction of the air outlet 1500. When the protective cover 3000 is installed in place, the limiting portion 3002 is inserted into the limiting groove 1710.

[0080] Taking the protective cover 3000 provided with a claw 3110 and the bracket 1600 provided with a hole 1610 as an example, when the protective cover 3000 is installed on the bracket 1600, since the claw 3110 is located on the inner side of the protective cover 3000, it is difficult to observe the coordination between the claw 3110 and the hole 1610 during the installation process of the protective cover 3000, which will reduce the assembly efficiency of the protective cover 3000.

[0081] To this end, in the present embodiment, the protective cover 3000 includes a limiting portion 3002, and the limiting portion 3002 is protruded relative to the edge of the protective cover 3000 along the radial direction of the air outlet 1500. In this way, during the installation of the protective cover 3000, the limiting portion 3002 can be observed at all times, so as to control the limiting portion 3002 to be inserted into the limiting groove 1710. The limiting portion 3002 cooperates with the limiting groove 1710 to achieve positioning, so that the claw 3110 and the hole 1610 can be cooperated (not limited to the cooperation between the claw 3110 and the hole 1610, and can also be applied to other connection methods), which is convenient and quick, and improves assembly efficiency.

[0082] In particular, when the first annular wall 3001 and the edge of the protective cover 3000 are arranged alternately, since the first annular wall 3001 is also positioned in coordination with the bracket 1600 through the pin 3120 and the socket 1620, a larger range of positioning and coordination of the protective cover 3000 from the center to its edge can be achieved, thereby enhancing the installation stability of the protective cover 3000.

[0083] Further, continue to combine Figure 3 As shown, the bracket 1600 is connected to the connecting platform 1700, so that the protective cover 3000 and the bracket 1600 share the connecting platform 1700, and it is no longer necessary to set up an additional connecting structure for the bracket 1600, thereby simplifying the structure.

[0084] The above description is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made based on the concept of the present application and the contents of the present application description and drawings, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
