Description

Technical Field

[0001] The present invention belongs to the technical field of electrical appliances, and particularly provides a filtering device, an oil fume extractor and an integrated stove including the filtering device. Background Art

[0002] An integrated stove is a kitchen appliance integrating multiple functions such as an oil fume extractor, a gas stove, a disinfection cabinet, and a storage cabinet, and is also called an environmental protection stove or an integrated environmental protection stove in the industry. It has the advantages of saving space, good oil fume extraction effect, energy saving, low consumption and environmental protection.

[0003] An integrated stove mainly includes a cooker and an oil fume extractor. The oil fume extractor mainly includes a housing, a fan and a filtering member arranged in the housing. Among them, the fan includes a motor, a volute and an impeller. After the power supply of the fan is connected, the motor drives the impeller to rotate, so that a negative pressure is formed in the housing of the fan, thereby sucking the oil fume above the cooker into the interior of the fan. When the oil fume passes through the filtering member, the oil in the oil fume is intercepted, and the filtered oil fume enters the interior of the fan housing, then enters the volute of the fan, and finally is discharged along a fixed path.

[0004] The patent application with the publication number CN109237575A discloses a dynamic oil mesh, which includes a mesh part. The mesh part includes a plurality of spokes, and at least some of the plurality of spokes include bending parts. This patent application discloses a circular oil mesh. The mesh part of the oil mesh includes a plurality of spokes. The strip-shaped spokes radiate and extend from the middle of the oil mesh to the periphery. In this way, the gap between two adjacent strip-shaped spokes becomes larger from small (see Figure 2 ) of the patent application document, that is, the gap near the center of the oil mesh is large, and the gap far from the center of the oil mesh is small. The gap between the strip-shaped spokes is closely related to the oil filtering effect of the oil mesh. Specifically, if the gap is too small, it is easy to cause the oil mesh to be blocked by the oil liquid filtered down. However, if the gap is too large, the oil filtering effect of the oil mesh becomes poor. Therefore, this circular oil mesh can only ensure that a part of it has a good oil filtering effect, and the oil filtering effect of the rest part is poor.

[0005] Therefore, there is a need for a new technical solution in the art to solve the above problems. Summary of the Invention

[0006] To solve the above problems in the prior art, that is, to solve the problem of poor overall oil filtering effect of the existing circular oil screen, the present invention provides a filtering device, which includes: two first disc-shaped members arranged opposite to each other; a connecting member disposed between the two first disc-shaped members to connect them; a filtering member including a plurality of filamentous members disposed between the two first disc-shaped members, and the plurality of filamentous members are only distributed along the circumferential direction of the first disc-shaped members, so as to form a gap with a filtering function between adjacent filamentous members; and a second disc-shaped member disposed in the middle area between the two first disc-shaped members to support the plurality of filamentous members.

[0007] In a preferred technical solution of the above filtering device, the filtering device has at least one oil collecting area for collecting the oil liquid attached to the filamentous members.

[0008] In a preferred technical solution of the above filtering device, the portions of the filamentous members on both sides of the second disc-shaped member respectively form an angle with the axes of the two first disc-shaped members, so that the oil liquid on the filamentous members can flow along the filamentous members from the second disc-shaped member towards the corresponding first disc-shaped member on each side as the filtering member rotates, thereby forming an oil collecting area at each position of the filtering device close to the two first disc-shaped members.

[0009] In a preferred technical solution of the above filtering device, in the assembled state, the portion of the filamentous member close to the first disc-shaped member and the portion close to the second disc-shaped member have a height difference, so that the oil liquid on the filamentous member can flow towards the first disc-shaped member or the second disc-shaped member under the action of its own gravity, thereby forming an oil collecting area at each position of the filtering device close to the two first disc-shaped members and the second disc-shaped member.

[0010] In a preferred technical solution of the above filtering device, the first disc-shaped member and the second disc-shaped member have the same radial dimension, and the oil collecting area is formed by the height difference between the installation positions of the portion of the filamentous member close to the first disc-shaped member and the portion close to the second disc-shaped member, or the first disc-shaped member and the second disc-shaped member have different radial dimensions, and the oil collecting area is formed by the difference between the radial dimension of the first disc-shaped member and the radial dimension of the second disc-shaped member.

[0011] In a preferred technical solution of the above filtering device, the connecting member includes a plurality of strip-shaped structures distributed along the circumferential direction of the first disc-shaped member.

[0012] In a preferred technical solution of the above filtering device, the strip-shaped structure is a strip-shaped blade, so that the first disc-shaped member can rotate naturally by the impact force of the oil fume on the windward surface of the strip-shaped blade.

[0013] In a preferred technical solution of the above filtering device, the gap between adjacent filamentous members is 4 to 6 mm.

[0014] On the other hand, the present invention also provides an oil fume extractor, which includes the above filtering device.

[0015] On the other hand, the present invention also provides an integrated cooking stove, which includes the above filtering device.

[0016] Those skilled in the art can understand that in a preferred technical solution of the present invention, the filtering device includes: two first disc-shaped members arranged oppositely; a connecting member arranged between the two first disc-shaped members to connect the two; and a filtering member including a plurality of filamentous members arranged between the two first disc-shaped members, and the plurality of filamentous members are only distributed along the circumferential direction of the first disc-shaped member, so as to form a gap with a filtering function between adjacent filamentous members; through such a setting, the gap between adjacent two filamentous members is kept unchanged, so that each part of the filtering member has the same filtering ability; in addition, the filtering device further includes a second disc-shaped member, and the second disc-shaped member is arranged in the middle area between the two first disc-shaped members to support the plurality of filamentous members; by supporting and strengthening the filamentous members through the second disc-shaped member, the stability of the filamentous members can be improved, and the normal operation of the filtering device can be ensured.

[0017] Furthermore, the filtering device further has at least one oil collecting area for collecting the oil liquid attached to the filamentous members. During the operation of the integrated cooking stove, the filtering device can intercept the grease in the oil fume, and the intercepted grease will adhere to the filamentous members. As the grease accumulates continuously, an oil liquid will be formed on the filamentous members. By providing an oil collecting area on the filtering device, the oil liquid attached to the filamentous members can be collected. In this way, it can be avoided that the gap between the filamentous members is blocked due to too much oil liquid on the filamentous members, so that the normal operation of the filtering device can be ensured.

[0018] Further, the portions of the filamentous member on both sides of the second disc-shaped member respectively form an angle with the axes of the two first disc-shaped members, so that the oil on the filamentous member can flow along the filamentous member from the second disc-shaped member towards the first disc-shaped members on the corresponding sides as the filtering member rotates, thereby forming an oil collection area at each position of the filtering device close to the two first disc-shaped members. With such a setting, when the filtering member rotates, under the action of centrifugal force, the oil on the filamentous member will flow from the middle along the filamentous member towards the first disc-shaped members on both sides, and the oil collection effect is good.

[0019] Further, the strip-shaped structure is a strip-shaped blade, so that the first disc-shaped member can rotate naturally by means of the impact force of the oil fume on the windward surface of the strip-shaped blade. With such a setting, when the fan operates, the first disc-shaped member can rotate naturally by means of the impact force of the oil fume on the windward surface of the strip-shaped blade. That is to say, even without a driving member, the filtering device can rotate naturally under the impact of the oil fume; in addition, by setting the strip-shaped structure as a strip-shaped blade, the obstruction to the oil fume can also be reduced when the driving member drives the filtering device to rotate.

[0035] The preferred implementation manners of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art should understand that the implementation manners described below are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0037] In addition, it should also be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it 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 directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0038] First, refer to Figure 1 and Figure 2 , where Figure 1 is the structural schematic diagram of the integrated stove of the present invention Figure 1 ; Figure 2 is the structural schematic diagram of the integrated stove of the present invention Figure 2 .

[0039] As Figure 1 and Figure 2 shown, the integrated stove of the present invention includes a cooking appliance 1 and a range hood. Among them, the range hood includes a housing 2, and the cooking appliance 1 is integrally arranged on the housing 2.

[0040] Continue to refer to Figure 1 and Figure 2, a smoke inlet 21 and a smoke outlet 22 are provided on the housing 2, and a smoke exhaust passage 23 is further provided inside the housing 2. The two ends of the smoke exhaust passage 23 are respectively communicated with the smoke inlet 21 and the smoke outlet 22. The cooking fume can enter from the smoke inlet 21, then flow along the smoke exhaust passage 23, and finally be discharged through the smoke outlet 22.

[0041] Continue to refer to Figure 2 , the range hood of the present invention further includes a fan 3. The fan 3 includes a volute 31, an impeller 32 is provided inside the volute 31. The fan 3 further includes a driving motor, denoted as the first motor 33. The output shaft of the first motor 33 is fixedly connected to the impeller 32 and can drive the impeller 32 to rotate. Among them, the fan 3 is arranged between the smoke exhaust passage 23 and the smoke outlet 22. The volute 31 has an air inlet (not shown in the figure) and an air outlet (not shown in the figure). Among them, the air inlet of the volute 31 is communicated with the smoke exhaust passage 23, and the air outlet of the volute 31 is communicated with the smoke outlet 22.

[0042] Continue to refer to Figure 1 and Figure 2 , the range hood of the present invention further includes a filtering device, and the filtering device is arranged in the smoke exhaust passage 23. The filtering device can filter the cooking fume in the smoke exhaust passage 23.

[0043] When the integrated stove is running, the fan 3 is started, and the first motor 33 drives the impeller 32 to rotate, so that a negative pressure is formed in the smoke exhaust passage 23, thereby sucking the cooking fume above the cooker 1 into the smoke exhaust passage 23. When the cooking fume passes through the filtering device, the grease in the cooking fume is intercepted by the filtering device, and the clean cooking fume is finally discharged outdoors through the smoke outlet 22.

[0044] From Figure 2 , it can be seen that the filtering device is arranged at a position close to the smoke inlet 21. In this way, when the cooking fume is sucked in, it can be preferentially filtered by the filtering device, and the grease in the cooking fume is intercepted by the filtering device, so as to reduce the pollution of the interior of the smoke exhaust passage 23 by the cooking fume, and also reduce the burden on the user to clean the interior of the smoke exhaust passage 23, and improve the user experience.

[0045] Continue to refer to Figure 1 and Figure 2 , and then refer to Figures 3 to 5 , among which, Figure 3 is a schematic structural diagram of the filtering device of the present invention; Figure 4 is Figure 3 a sectional view taken along line A-A in Figure 5 is Figure 4 a partial enlarged view in

[0046] As Figures 1 to 4 shown, the filtering device of the present invention includes a first disk-shaped member 4, a filtering member 5, a connecting member and a second disk-shaped member 7.

[0047] Among them, the number of the first disc-shaped members 4 is two, and the two first disc-shaped members 4 are arranged opposite to each other left and right. The connecting member is arranged between the two first disc-shaped members 4 so as to connect the two first disc-shaped members 4 and make the two first disc-shaped members 4 relatively fixed; the filtering member 5 includes a plurality of filamentous members 51, and the plurality of filamentous members 51 are all arranged between the two first disc-shaped members 4, and moreover, the plurality of filamentous members 51 are only distributed along the circumferential direction of the first disc-shaped member 4, so as to form a gap with a filtering function between two adjacent filamentous members 51. In this way, the gap between two adjacent filamentous members 51 is kept unchanged, so that each part of the filtering member 5 has the same filtering ability; among them, the gap between adjacent filamentous members 51 is preferably set to 4 to 6 mm; the second disc-shaped member 7 is arranged in the middle area between the two first disc-shaped members 4 and can support and strengthen the plurality of filamentous members 51. The filtering device is in the shape of a long cylinder, generally with a relatively long length, and the length of the filamentous member 51 is also relatively long, resulting in poor stability of the filamentous member 51. By supporting and strengthening the filamentous member 51 through the second disc-shaped member 7, the stability of the filamentous member 51 can be improved, ensuring the normal operation of the filtering device.

[0048] Continue to refer to Figure 1 , the filtering member 5 includes a motor, denoted as the second motor 8, and the second motor 8 is fixed on the housing 2, and the output shaft of the second motor 8 is fixedly connected to the first disc-shaped member 4.

[0049] Exemplarily, a rotating shaft 43 is provided on each of the two first disc-shaped members 4. The second motor 8 is arranged on the left and is fixedly connected to the rotating shaft 43 on the first disc-shaped member 4 located on the left. The rotating shaft 43 on the first disc-shaped member 4 located on the right is rotatably connected to the housing 2. When the integrated range hood operates, the second motor 8 drives the first disc-shaped member 4 to rotate, and thus drives the filtering member 5 to rotate. The rotating filtering member 5 has a better filtering effect on the oil fume.

[0050] Preferably, the filtering device has an oil collecting area for collecting the oil liquid adhering to the filamentous member 51. During the operation of the integrated range hood, the filtering device can intercept the grease in the oil fume, and the intercepted grease will adhere to the filamentous member 51. As the grease continuously accumulates, an oil liquid will be formed on the filamentous member 51. By providing an oil collecting area on the filtering device, the oil liquid adhering to the filamentous member 51 can be collected. In this way, it is possible to avoid the situation that the gap between the filamentous members 51 is blocked due to too much oil liquid on the filamentous member 51, thus ensuring the normal operation of the filtering device. Among them, the number of the oil collecting areas can be one, two or three, etc. Such adjustments and changes to the specific number of the oil collecting areas do not deviate from the principle and scope of the present invention and should be limited within the protection scope of the present invention.

[0051] In a preferred embodiment, as Figure 3 shown, the portions of the filamentous member 51 on both sides of the second disc-shaped member 7 respectively have an included angle with the axes (such as the dash-dotted lines in the figure) of the two first disc-shaped members 4, so that the oil on the filamentous member 51 can flow along the filamentous member 51 from the second disc-shaped member 7 towards the first disc-shaped members 4 on the corresponding sides respectively as the filtering member 5 rotates, thereby forming an oil collecting area at each position of the filtering device close to the two first disc-shaped members 4.

[0052] That is to say, the number of oil collecting areas is two, which are respectively located at the first disc-shaped member 4 on the left and the first disc-shaped member 4 on the right. For the convenience of description, the filtering device can be divided into two left and right regions. Among them, the region between the second disc-shaped member 7 and the first disc-shaped member 4 on the left is denoted as the first region, and the region between the second disc-shaped member 7 and the first disc-shaped member 4 on the right is denoted as the second region. As can be seen from Figure 3 this, the filamentous member 51 in the first region does not extend along the axis direction of the first disc-shaped member 4, but extends obliquely. In this way, an included angle is formed between the filamentous member 51 in this region and the axis of the first disc-shaped member 4. Similarly, the filamentous member 51 in the second region also extends obliquely. In this way, an included angle is also formed between the filamentous member 51 in this region and the axis of the first disc-shaped member 4. When the second motor 8 drives the filtering member 5 to rotate clockwise, under the action of centrifugal force, the oil on the filamentous member 51 in the first region will flow along the filamentous member 51 towards the first disc-shaped member 4 on the left, and the oil on the filamentous member 51 in the second region will flow along the filamentous member 51 towards the first disc-shaped member 4 on the right. In this way, an oil collecting area is formed at each position of the filtering device close to the first disc-shaped member 4 on the left and the first disc-shaped member 4 on the right.

[0053] In another preferred embodiment, the radial dimensions of the first disc-shaped member 4 and the second disc-shaped member 7 are different, so that there is a height difference between the portion of the filamentous member 51 close to the first disc-shaped member 4 and the portion close to the second disc-shaped member 7, so that the oil on the filamentous member 51 can flow towards the first disc-shaped member 4 or the second disc-shaped member 7 under the action of its own gravity, thereby forming an oil collecting area at each position of the filtering device close to the two first disc-shaped members and the second disc-shaped member.

[0054] That is to say, the number of oil collection areas is three, which are respectively located in the first disk-shaped member 4 on the left, the second disk-shaped member 7 in the middle, and the first disk-shaped member 4 on the right. Exemplarily, the radial dimension of the first disk-shaped member 4 is smaller than that of the second disk-shaped member 7. When the filtering device is in a static state, in the vertical direction, the filtering device can be divided into upper and lower half areas. Among them, for the filamentous member 51 in the upper half area, the height of the part close to the first disk-shaped member 4 is lower than that of the part close to the second disk-shaped member 7, so that the oil on the filamentous member 51 in this area can flow along the filamentous member 51 from the middle to both left and right ends under the action of its own gravity and gather in the first disk-shaped members 4 on both sides; on the contrary, for the filamentous member 51 in the lower half area, the height of the part close to the first disk-shaped member 4 is higher than that of the part close to the second disk-shaped member 7, so that the oil on the filamentous member 51 in this area can flow along the filamentous member 51 from both left and right ends to the middle under the action of its own gravity and gather in the second disk-shaped member 7. In this way, an oil collection area is formed at the position of the first disk-shaped member 4 on the left, the second disk-shaped member 7 in the middle, and the first disk-shaped member 4 on the right of the filtering device respectively.

[0055] It should be noted that in the above preferred embodiment, due to the different radial dimensions of the first disk-shaped member 4 and the second disk-shaped member 7, the oil collection area is formed by the difference between the radial dimension of the first disk-shaped member 4 and the radial dimension of the second disk-shaped member 7. In actual application, the radial dimensions of the first disk-shaped member 4 and the second disk-shaped member 7 can also be the same. In this case, the installation position of the part of the filamentous member 51 close to the first disk-shaped member 4 and the installation position of the part close to the second disk-shaped member 7 can have a height difference, and the oil collection area is formed through this height difference.

[0056] In addition, it should also be noted that multiple filamentous members 51 can be composed of multiple independent filamentous members 51. That is to say, each filamentous member 51 is an independent monomer, and both ends of each filamentous member 51 are fixedly connected to the two first disk-shaped members 4 respectively; or, multiple filamentous members 51 can also be composed of a longer filamentous member 51 wound back and forth between the two first disk-shaped members 4, similar to a tennis racket or a badminton racket. That is to say, each filamentous member 51 is continuous without interruption. Exemplarily, one end of the filamentous member 51 is fixed to the first disk-shaped member 4 on the left, then extends to the first disk-shaped member 4 on the right. After extending to the first disk-shaped member 4 on the right, it turns back and extends to the first disk-shaped member 4 on the left. After extending to the first disk-shaped member 4 on the left, it turns back and extends to the first disk-shaped member 4 on the right, and so on.

[0057] Continue to refer to Figure 4 and Figure 5, a first disc-shaped member 4 is provided with a groove 41 at a position corresponding to the filamentous member 51, and the filamentous member 51 is received in the groove 41. Among them, the filamentous member 51 is preferably a steel wire.

[0058] Continue to refer to Figure 4 , a hollow structure 42 is provided on the first disc-shaped member 4. Among them, the number of the hollow structures 42 is 4, and they are evenly distributed. By providing the hollow structure 42, not only can the weight of the filtering device be reduced, which is beneficial to the high-speed rotation of the filtering device and improves the oil filtering effect, but also the aesthetics of the filtering device can be improved. Of course, the number of the hollow structures 42 is not limited to the above-mentioned 4. For example, it can also be 2 or 5, etc. Such adjustments and changes to the specific number of the hollow structures do not deviate from the principle and scope of the present invention and should be limited within the protection scope of the present invention.

[0059] Continue to refer to Figure 3 and Figure 4 , the connecting member includes a plurality of strip-shaped structures 6. Exemplarily, the number of the strip-shaped structures 6 is 5, and the 5 strip-shaped structures 6 are circumferentially distributed between two first disc-shaped members 4 along the circumferential direction of the first disc-shaped member 4; preferably, the 5 strip-shaped structures 6 are evenly distributed.

[0060] It should be noted that those skilled in the art can, in actual application, according to actual needs, only set one strip-shaped structure 6. Such adjustments and changes to the specific number of the strip-shaped structures 6 do not deviate from the principle and scope of the present invention and should be limited within the protection scope of the present invention.

[0061] Continue to refer to Figure 3 and Figure 4 , the strip-shaped structure 6 is a strip-shaped blade, similar to the impeller 32 of the fan 3. In this way, when the fan 3 operates, the first disc-shaped member 4 can rotate naturally by means of the impact force of the oil fume on the windward surface of the strip-shaped blade. That is to say, even if the second motor 8 is not started, the filtering device can rotate naturally under the impact of the oil fume; in addition, by setting the strip-shaped structure 6 as a strip-shaped blade, when the second motor 8 drives the filtering device to rotate, the obstruction to the oil fume can also be reduced.

[0062] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
