Description

Technical Field

[0001] The present invention belongs to the technical field of electrical equipment, and specifically provides a filtering device, a range hood and an integrated stove comprising the filtering device. Background Art

[0002] Integrated stove is a kitchen appliance that integrates multiple functions such as range hood, gas stove, disinfection cabinet, storage cabinet, etc. It is also called environmentally friendly stove or integrated environmentally friendly stove in the industry. It has the advantages of saving space, good range hood extraction effect, energy saving, low consumption and environmental protection.

[0003] The integrated stove mainly includes a stove and a range hood. The range hood mainly includes a shell and a fan and a filtering component arranged in the shell. The fan includes a motor, a volute and a wind wheel. After being connected to the power supply of the fan, the motor drives the wind wheel to rotate, so that a negative pressure is formed in the shell of the fan, thereby sucking the oil smoke above the stove into the interior of the fan. When the oil smoke passes through the filtering component, the grease in the oil smoke is intercepted, and the filtered oil smoke enters the interior of the fan shell, and then enters the volute of the fan, and is finally discharged along a fixed passage.

[0004] Patent application with publication number CN109237575A discloses a dynamic oil net, including a net portion, the net portion includes a plurality of spokes, at least some of the spokes include a curved portion. The patent application discloses a circular oil net, the net portion of the oil net includes a plurality of spokes, the strip spokes extend radially from the middle of the oil net to the surroundings, so that the gap between two adjacent strip spokes changes from small to large (see the patent application document for details). Figure 2 ), that is to say, the gap close to the center of the oil net is large, and the gap far away from the center of the oil net is small. The gap between the strip spokes is closely related to the oil filtering effect of the oil net. Specifically, if the gap is too small, the oil net will be easily blocked by the filtered oil. However, if the gap is too large, the oil filtering effect of the oil net will deteriorate. Therefore, this circular oil net can only ensure that a part of it has a good oil filtering effect, and the oil filtering effect of the rest is poor.

[0005] Therefore, this field needs a new technical solution to solve the above problems. Summary of the invention

[0006] In order to solve the above-mentioned problems in the prior art, that is, to solve the problem that the overall oil filtering effect of the existing circular oil net is poor, the present invention provides a filtering device, which includes: two disc-shaped components arranged opposite to each other; a connecting component, which is arranged between the two disc-shaped components to connect the two; and a filtering component, including a plurality of filamentary components arranged between the two disc-shaped components, and the plurality of filamentary components are only distributed along the circumference of the disc-shaped components, so as to form a gap with filtering function between adjacent filamentary components; wherein the filtering device has at least one oil collecting area to collect oil attached to the filamentary components.

[0007] In the preferred technical solution of the above-mentioned filtering device, there is an angle between the filamentary component and the axes of the two disc-shaped components, so that the oil on the filamentary component can flow along the filamentary component toward one of the two disc-shaped components as the filtering component rotates, thereby forming an oil collecting area in the filtering device close to the disc-shaped component.

[0008] In the preferred technical solution of the above-mentioned filtering device, in the assembled state, there is a height difference between the part of the filamentary member close to one of the two disc-shaped members and the part close to the other disc-shaped member, so that the oil on the filamentary member can flow to the disc-shaped member with a lower height among the two disc-shaped members under the action of its own gravity, thereby forming an oil collecting area at each position of the filtering device close to the two disc-shaped members.

[0009] In a preferred technical solution of the above-mentioned filtering device, the radial dimensions of the two disc-shaped components are the same, and the filamentary component forms the oil collecting area by the height difference between the installation position of the part close to one of the two disc-shaped components and the installation position of the part close to the other disc-shaped component.

[0010] In a preferred technical solution of the above-mentioned filtering device, radial dimensions of the two disc-shaped components are different, and the filament-shaped component forms the oil collecting area through the difference in radial dimensions of the two disc-shaped components.

[0011] In a preferred technical solution of the above-mentioned filter device, the connecting member includes a plurality of strip structures distributed along the circumference of the disc-shaped member.

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

[0013] In a preferred technical solution of the above-mentioned filtering device, a hollow structure is provided on the disc-shaped component.

[0014] In another aspect, the present invention further provides a range hood, comprising the above-mentioned filtering device.

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

[0016] It can be understood by those skilled in the art that in the preferred technical solution of the present invention, the filter device includes: two disc-shaped components arranged opposite to each other; a connecting component, which is arranged between the two disc-shaped components to connect the two; and a filter component, including a plurality of filamentary components arranged between the two disc-shaped components, and the plurality of filamentary components are only distributed along the circumference of the disc-shaped components, so as to form a gap with a filtering function between adjacent filamentary components. Through such an arrangement, the gap between the two adjacent filamentary components remains unchanged, so that each part of the filter component has the same filtering capacity. In addition, the filter device also has an oil collection area to collect the oil attached to the filamentary component. During the operation of the integrated stove, the filter device can intercept the grease in the oil smoke, and the intercepted grease will adhere to the filamentary component. As the grease continues to accumulate, oil will be formed on the filamentary component. By setting the oil collection area on the filter device, the oil attached to the filamentary component can be collected. In this way, it is possible to avoid the situation where the gap between the filamentary components is blocked due to excessive oil on the filamentary component, thereby ensuring the normal operation of the filter device.

[0017] Furthermore, there is an angle between the axes of the filamentary member and the disc-shaped member, so that the oil on the filamentary member can flow along the filamentary member toward one of the two disc-shaped members as the filter member rotates, thereby forming an oil collection area at a position of the filter device close to the disc-shaped member. With such an arrangement, when the filter member rotates, under the action of centrifugal force, the oil on the filamentary member will flow along the filamentary member toward the oil collection area, and the oil collection effect is good.

[0018] Furthermore, the strip structure is a strip blade, so that the disc-shaped member can rotate naturally with the help of the impact of the oil smoke on the windward surface of the strip blade. Through such an arrangement, when the fan is running, the disc-shaped member can rotate naturally with the help of the impact of the oil smoke on the windward surface of the strip blade, that is, even without a driving member, the filter device can rotate naturally under the impact of the oil smoke; in addition, by setting the strip structure as a strip blade, when the driving member drives the filter device to rotate, the obstruction to the oil smoke can also be reduced.

[0019] Furthermore, a hollow structure is provided on the disc-shaped component. By providing the hollow structure, the weight of the filter device can be reduced, the filter device can be more easily rotated, and the aesthetics of the filter device can be improved.

[0036] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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 a direct connection or an indirect connection through an intermediate medium, and it can be the internal communication of 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 circumstances.

[0037] First refer to Figure 1 and Figure 2 ,in, Figure 1 The structure of the integrated stove of the present invention is shown in FIG. Figure 1 ; Figure 2 The structure of the integrated stove of the present invention is shown in FIG. Figure 2 .

[0038] like Figure 1 and Figure 2 As shown, the integrated stove of the present invention includes a stove 1 and a range hood, wherein the range hood includes a shell 2, and the stove 1 is integrated into the shell 2.

[0039] Continue reading Figure 1 and Figure 2 The shell 2 is provided with a smoke inlet 21 and a smoke outlet 22, and a smoke exhaust channel 23 is also provided in the shell 2, and both ends of the smoke exhaust channel 23 are respectively connected with the smoke inlet 21 and the smoke outlet 22. Oil smoke can enter from the smoke inlet 21, then flow along the smoke exhaust channel 23, and finally be discharged through the smoke outlet 22.

[0040] Continue reading Figure 2 The range hood of the present invention further comprises a fan 3, which comprises a volute 31, an impeller 32 is arranged in the volute 31, and the fan 3 further comprises a driving motor, which is denoted as a first motor 33, and the output shaft of the first motor 33 is fixedly connected to the impeller 32, and can drive the impeller 32 to rotate. The fan 3 is arranged between the smoke exhaust passage 23 and the smoke outlet 22, and the volute 31 has an air inlet (not shown in the figure) and an air outlet (not shown in the figure), wherein the air inlet of the volute 31 is connected to the smoke exhaust passage 23, and the air outlet of the volute 31 is connected to the smoke outlet 22.

[0041] Continue reading Figure 1 and Figure 2 The range hood of the present invention further comprises a filtering device, which is arranged in the smoke exhaust channel 23. The filtering device can filter the oil smoke in the smoke exhaust channel 23.

[0042] When the integrated stove is running, the fan 3 starts, and the first motor 33 drives the impeller 32 to rotate, so that negative pressure is formed in the smoke exhaust channel 23, so that the oil smoke above the stove 1 is sucked into the smoke exhaust channel 23 from the smoke inlet 21. When the oil smoke passes through the filtering device, the grease in the oil smoke is intercepted by the filtering device, and the clean oil smoke is finally discharged to the outside through the smoke outlet 22.

[0043] from Figure 2 It can be seen that the filter device is arranged near the smoke inlet 21. In this way, when the oil smoke is inhaled, it can be filtered by the filter device first, and the grease in the oil smoke is intercepted by the filter device to reduce the pollution to the inside of the smoke exhaust channel 23, thereby reducing the user's burden of cleaning the inside of the smoke exhaust channel 23 and improving the user's experience.

[0044] Continue reading Figure 1 and Figure 2 , and then see Figures 3 to 5 ,in, Figure 3 It is a schematic diagram of the structure of the filtering device of the present invention; Figure 4 for Figure 3 Sectional view at AA in the middle; Figure 5 for Figure 4 A partial enlarged view of the .

[0045] like Figures 1 to 4 As shown, the filtering device of the present invention comprises a disc-shaped member 4, a filtering member 5 and a connecting member.

[0046] Among them, there are two disc-shaped components 4, and the two disc-shaped components 4 are arranged opposite to each other on the left and right. The connecting component is arranged between the two disc-shaped components 4 so as to connect the two disc-shaped components 4 and make the two disc-shaped components 4 relatively fixed. In this way, the two disc-shaped components 4 and the connecting component arranged between the two disc-shaped components 4 jointly build a stable frame structure.

[0047] The filter member 5 includes a plurality of filamentary members 51, which are arranged between two disc-shaped members 4, and the plurality of filamentary members 51 are only distributed along the circumference of the disc-shaped member 4, so that a gap with filtering function is formed between two adjacent filamentary members 51, so that the gap between the two adjacent filamentary members 51 remains unchanged, so that each part of the filter member 5 has the same filtering capacity. The gap between adjacent filamentary members 51 is preferably set to 4 to 6 mm.

[0048] The filter device has an oil collection area to collect the oil attached to the filamentary member 51. During the operation of the integrated stove, the filter device can intercept the oil in the oil smoke, and the intercepted oil will adhere to the filamentary member 51. As the oil continues to accumulate, oil will form on the filamentary member 51. By setting the oil collection area on the filter device, the oil attached to the filamentary member 51 can be collected. In this way, it is possible to avoid the situation where the gaps between the filamentary members 51 are blocked due to excessive oil on the filamentary member 51, thereby ensuring the normal operation of the filter device. The number of oil collection areas can be one, two or three, etc. The adjustment and change of the specific number of oil collection areas does not deviate from the principle and scope of the present invention, and should be limited within the protection scope of the present invention.

[0049] In a preferred embodiment, Figure 3 As shown, there is an angle between the filamentary component 51 and the axes of the two disc-shaped components 4 (such as the dotted lines in the figure), so that the oil on the filamentary component 51 can flow along the filamentary component 51 toward one of the two disc-shaped components 4 as the filter component 5 rotates, thereby forming an oil collecting area at the position of the filter device close to the disc-shaped component 4.

[0050] from Figure 3 It can be seen from the figure that the filamentary member 51 does not extend along the axial direction of the two disc-shaped members 4, and there is an angle between the extending direction of the filamentary member 51 and the axial direction of the disc-shaped member 4. For example, the disc-shaped member 4 on the left has a fixing position A for fixing the filamentary member 51. 1 , A 2 , A 3 ...An, the right disc-shaped member 4 has a fixing position B for fixing the filament-shaped member 51 1 , B 2 , B 3 …Bn,A 1 With B 1 On the same horizontal line, A 2 With B 2 On the same horizontal line, A 3 With B 3On the same horizontal line, A n With B n When the filamentary member 51 is installed, if the left end of the filamentary member 51 is on the same horizontal line as A 1 The right end of the filamentary member 51 is fixed to B 2 Similarly, if the left end of the filamentary member 51 is fixed to A 2 The right end of the filamentary member 51 is fixed to B 3 If the left end of the filamentary member 51 is fixed to A n The right end of the filamentary member 51 is fixed to B 1 Fixed, that is, the two ends of the filamentary component 51 are staggered and fixed, so that an angle is formed between the filamentary component 51 and the axes of the two disc-shaped components 4. When the filter component 5 rotates clockwise, under the action of centrifugal force, the oil on the filamentary component 51 will flow along the filamentary component 51 toward the disc-shaped component 4 on the right side. In this way, the filter device forms an oil collecting area near the disc-shaped component 4 on the right side.

[0051] It should be noted that the left and right ends of the filamentary component 51 can be installed at one fixed position, or at two or three fixed positions. Such flexible adjustment and change does not deviate from the principle and scope of the present invention and should be limited within the protection scope of the present invention.

[0052] In another preferred embodiment, the radial dimensions of the two disc-shaped components 4 are different, so that there is a height difference between the portion of the filamentary component 51 close to the disc-shaped component 4 on the left and the portion of the disc-shaped component 4 close to the right, so that the oil on the filamentary component 51 can flow to the disc-shaped component 4 with a lower height under the action of its own gravity, thereby forming an oil collection area at each position of the filtering device close to the two disc-shaped components 4.

[0053] Exemplarily, the diameter of the disk-shaped member 4 on the left side can be made larger than the diameter of the disk-shaped member 4 on the right side. When the filtering device is in a stationary state, the filtering device can be divided into two upper and lower half areas along the vertical direction, wherein the left end of the filamentary member 51 located in the upper half area is higher than the right end. Therefore, under the action of the oil's own gravity, the oil on the filamentary member 51 in the upper half area can flow from left to right along the filamentary member 51 and gather to the disk-shaped member 4 on the right side; on the contrary, the right end of the filamentary member 51 located in the lower half area is higher than the left end. Therefore, under the action of the oil's own gravity, the oil on the filamentary member 51 in the lower half area can flow from right to left along the filamentary member 51 and gather to the disk-shaped member 4 on the left side. In this way, the filtering device forms an oil collecting area at the position close to the disk-shaped member 4 on the left side and the disk-shaped member 4 on the right side.

[0054] It should be noted that, in the above-mentioned preferred embodiment, since the radial dimensions of the two disk-shaped components 4 are different, the filamentary component 51 is an oil collecting area formed by the difference in the radial dimensions of the two disk-shaped components 4. In actual applications, the radial dimensions of the two disk-shaped components 4 can also be made the same. In this case, there can be a height difference between the installation position of the part of the filamentary component 51 close to the disk-shaped component 4 on the left and the installation position of the part of the disk-shaped component 4 close to the right, and an oil collecting area is formed by this height difference.

[0055] In addition, it should be noted that, in order to collect the oil, an oil collecting structure, such as an oil collecting tank or an oil collecting box, etc., may be provided on the disc-shaped member 4 .

[0056] In addition, it should be noted that the multiple filamentary components 51 can be composed of multiple independent filamentary components 51, that is, each filamentary component 51 is an independent monomer, and the two ends of each filamentary component 51 are respectively fixedly connected to the two disc-shaped components 4; or, the multiple filamentary components 51 can also be composed of a longer filamentary component 51 reciprocatingly wound around the two disc-shaped components 4, similar to a tennis racket or a badminton racket, that is, each filamentary component 51 is continuous without interruption. For example, one end of the filamentary component 51 is fixed to the disc-shaped component 4 on the left, and then extends to the disc-shaped component 4 on the right. After extending to the disc-shaped component 4 on the right, it turns back and extends to the disc-shaped component 4 on the left. After extending to the disc-shaped component 4 on the left, it turns back and extends to the disc-shaped component 4 on the right, and so on.

[0057] Continue reading Figure 4 and Figure 5 The disc-shaped member 4 is provided with a groove 41 at a position corresponding to the filament-shaped member 51, and the filament-shaped member 51 is accommodated in the groove 41. The filament-shaped member 51 is preferably a steel wire.

[0058] Continue reading Figure 4 , a hollow structure 42 is provided on the disc-shaped member 4. The number of the hollow structures 42 is 4 and they are evenly distributed. By providing the hollow structure 42, the weight of the filter device can be reduced, which is conducive to the high-speed rotation of the filter device, improves the oil filtering effect, and improves the aesthetics of the filter device. Of course, the number of the hollow structures 42 is not limited to the above 4, for example, it can also be 2 or 5, etc. Such adjustment and change of the specific number of the hollow structures does 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 reading Figure 1 The filter component 5 includes a motor, which is referred to as a second motor 7 . The second motor 7 is fixed on the housing 2 , and an output shaft of the second motor 7 is fixedly connected to the disc-shaped component 4 .

[0060] Exemplarily, a rotating shaft 43 is provided on each of the two disc-shaped components 4, and the second motor 7 is arranged on the left side and fixedly connected to the rotating shaft 43 on the disc-shaped component 4 on the left side. The rotating shaft 43 on the disc-shaped component 4 on the right side is rotatably connected to the shell 2. When the integrated stove is running, the second motor 7 drives the disc-shaped component 4 to rotate, and thereby drives the filter component 5 to rotate. The rotating filter component 5 has a better filtering effect on oil smoke.

[0061] Continue reading Figure 3 and Figure 4 The connecting member includes a plurality of strip structures 6. Exemplarily, the number of the strip structures 6 is 5, and the 5 strip structures 6 are distributed between the two disc-shaped members 4 along the circumference of the disc-shaped member 4; preferably, the 5 strip structures 6 are evenly distributed.

[0062] It should be noted that, in practical applications, those skilled in the art may only set one strip structure 6 according to actual needs. Such adjustment and change to the specific number of strip structures 6 does not deviate from the principle and scope of the present invention and should be limited within the protection scope of the present invention.

[0063] Continue reading Figure 3 and Figure 4 The strip structure 6 is a strip blade, similar to the impeller 32 of the fan 3. In this way, when the fan 3 is running, the disc-shaped member 4 can rotate naturally with the help of the impact of the oil smoke on the windward surface of the strip blade. That is to say, even if the second motor 7 is not started, the filter device can rotate naturally under the impact of the oil smoke; in addition, by setting the strip structure 6 as a strip blade, when the second motor 7 drives the filter device to rotate, the obstruction to the oil smoke can also be reduced.

[0064] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying 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.
