Description

Filtering component and kitchen processor

Technical Field

Embodiments of the present disclosure relate generally to the field of household appliances, and more particularly, to a filter assembly and a kitchen disposer.

Background

Kitchen processors, such as blenders, on the market today are capable of performing different functions, such as cutting, chopping or cooking for food preparation. Typically, blenders include various accessories for different applications.

In recent years, blenders having a juice squeezing function have become popular. After the blender cuts or shreds the vegetables or fruits, juice is separated from the pulp using the juice extractor accessory. However, such a mixer is complex in structure and has many parts for assembly/disassembly and washing/cleaning is required. In addition, the disassembly and cleaning of the parts with complex structures may make the operation complex, resulting in an overall juice extraction time being prolonged, affecting the user experience.

Disclosure of Invention

Embodiments of the present disclosure provide a filter assembly that is designed to overcome at least the problems of the filter assemblies of the prior art kitchen processors.

Embodiments of the present disclosure relate to a filter assembly, comprising a base adapted to be coupled to a shaft of a kitchen cooking machine and configured to rotate about an axis under the drive of the shaft; the filter cartridge is detachably arranged on the base, and the net-shaped side wall of the filter cartridge extends along the direction away from the base; and a cover portion extending inwardly from a first edge of the filter cartridge remote from the first end of the base and including an opening.

According to the embodiment of the disclosure, when the filter assembly is arranged on the rotating shaft of the kitchen processor to work, the rotation of the base drives the liquid in the filter cartridge to flow and generate vortex, so that residues such as pulp can be accumulated on the side wall of the filter cartridge continuously in a direction away from the base, and excessive residues cannot be accumulated around the connecting part of the filter cartridge and the base, so that the residues cannot overflow from the detachable connecting part of the filter cartridge and the base.

In some embodiments, the cover includes a first cover that is one-piece with the mesh sidewall. In such an embodiment, the first cap portion is non-removable from the mesh-like sidewall to ensure that debris can be prevented from escaping from the interior of the filter cartridge to the exterior of the filter cartridge as it accumulates toward the first cap portion.

In some embodiments, the cover comprises a second cover, and the base comprises: a base extending in a first plane perpendicular to the axis; and a bracket extending from the base in a direction away from the base and fixed to the second cover portion such that the second cover portion abuts on the first edge. In such an embodiment, the second cover portion is supported at the first edge by the bracket to prevent debris from escaping from the upper portion of the filter cartridge to the exterior of the filter cartridge.

In some embodiments, the second cap includes a cap flange extending inwardly from the first edge in a second plane parallel to the first plane, and the filter cartridge includes a cartridge flange extending inwardly from the first edge in a third plane parallel to the first plane, wherein the cap flange is removably coupled to the cartridge flange. In such an embodiment, the provision of the stacked inwardly extending flanges enables the filter cartridge and the second cover portion to be brought into close engagement, further ensuring that filtration residue does not escape from between the filter cartridge and the second cover portion.

In some embodiments, the cartridge flange comprises a through hole and the cap flange comprises a hook-type stop, wherein the hook-type stop is disposed on an end face of the cap flange facing the cartridge flange and passes through the through hole to limit movement of the cartridge flange in a direction parallel to the axis. In such embodiments, after the hook-type stopper passes through the through-hole in the barrel flange, the bent portion of the hook-type stopper can be rotated above the through-hole edge of the barrel flange, such as by rotating the filter cartridge relative to the base, such that the through-hole inner wall abuts against the side wall of the hook-type stopper. Thereby, the filter cartridge can be locked to the base.

In some embodiments, the support includes a plurality of support plates extending from an edge of the base toward the axis, and the plurality of support plates are equally spaced in a circumferential direction about the axis. In such embodiments, the support plate extends inwardly toward the axis, for example, from the edge of the base, thereby forming vanes for agitating the food in the filter assembly, thereby improving the filtration efficiency. At the same time, the support plate can firmly support the second cover part at the first edge.

In some embodiments, the cover includes a first cover coupled to the filter cartridge and a second cover coupled to the base, wherein a surface of the first cover facing the base abuts a surface of the second cover facing away from the base. In such embodiments, the filter assembly includes a first cover portion and a second cover portion that overlap together, the second cover portion further inward being capable of providing rigidity to the first cover portion. In this way, the first and second cover portions can cooperate to provide a more airtight and robust structure.

In some embodiments, the base includes an outer peripheral surface extending in a circumferential direction about the axis, a chute is provided on the outer peripheral surface, the chute includes a first section extending in a direction parallel to the axis and a second section extending in a direction perpendicular to the axis, and the filter cartridge includes a radial projection extending inwardly from an inner wall of the filter cartridge at a second end thereof proximate the base into the second section of the chute to limit movement of the filter cartridge relative to the base in the direction parallel to the axis. In such an embodiment, by providing the protrusions and the sliding grooves, the connection of the base and the filter cartridge can be made more stable.

In some embodiments, the cover extends from the rim in an oblique direction toward the base. In such embodiments, by providing an inclined cover portion, food added to the filter assembly can be directed. In some embodiments, the angled cover portion is shaped to mate with a guide surface of an additional funnel device to provide support for the funnel device.

A second aspect of the present disclosure relates to a kitchen machine. The kitchen cooking machine includes: a container including a rotation shaft hole; the rotating shaft extends into the container through the rotating shaft hole; and a filter assembly according to the first aspect of the present disclosure disposed within the container and coupled to the rotating shaft.

Detailed Description

The principles of the present disclosure will now be described with reference to various exemplary embodiments shown in the drawings. It should be understood that these embodiments are merely provided to enable those skilled in the art to better understand and further practice the present disclosure and are not intended to limit the scope of the present disclosure in any way. It should be noted that similar or identical reference numerals may be used, where possible, in the figures and similar or identical reference numerals may designate similar or identical functions. Those skilled in the art will readily recognize from the following description that alternative embodiments of the structures and methods illustrated herein may be employed without departing from the principles of the disclosure described herein.

As used herein, the term "comprising" and variants thereof are to be construed as meaning open-ended terms including, but not limited to. The term "based on" will be read as "based at least in part on". The terms "one embodiment" and "an embodiment" should be understood as "at least one embodiment". The term "another embodiment" should be understood as "at least one other embodiment". The terms "first," "second," and the like, may refer to different or the same object. Other explicit and implicit definitions may be included below. Unless the context clearly indicates otherwise, the definition of terms is consistent throughout the specification.

As described above, the kitchen processor has, for example, a component capable of performing a juice squeezing function. These components can be operated by the motor of the kitchen processor. As an accessory to be connected to a kitchen disposer, juicing filters often need to be secured to the output shaft of the motor in place of other serving operating parts prior to filtering. After the juice extraction is performed, the juice extractor filter needs to be cleaned of residues inside it for subsequent use. In this use, the user is required to disassemble the juice extracting member.

Conventionally, in order to achieve the removal of the juice extractor filter element, a removable cover is usually provided on the bowl-shaped juice extractor filter. However, during use, residue in the juice extractor filter element can accumulate on the sidewall in a direction away from the bottom. When the residue accumulates at the junction of the cap and the filter member, the residue may pass between the junctions and eventually overflow to the outside of the filter member, resulting in the resulting juice having a residue, which deteriorates the quality of the juice.

In view of the foregoing, embodiments of the present disclosure provide a filter assembly in which a filter cartridge is detachably connected to a base at a position close to the base. In such embodiments, the filter cartridge of the filter assembly is removably coupled to the base. In this way, pulp and the like residue accumulates on the side walls of the cartridge in a direction away from the base during use, without reaching the junction of the cartridge and the base. Thus, the fruit and vegetable residues can be prevented from overflowing from the connecting part of the filter cartridge and the base due to excessive accumulation.

A filter assembly according to the present disclosure will be described in detail below in conjunction with fig. 1 to 6.

Fig. 1 shows a schematic view of a kitchen food processor 1 according to an exemplary embodiment of the present disclosure. As shown in fig. 1, the kitchen processor 1 includes a main body 50 at a lower portion. An electric motor for driving the respective components is provided in the main body 50. The motor has an output shaft 20 extending along an axis a. The output shaft 20 passes through the spindle bore 41 of the juicer container 40 and is coupled with the filter assembly 10 in the container 40 such that the filter assembly 10 is rotatable with the output shaft 20 about axis a. During the juice extraction process, filter assembly 10 is rotated by the motor and the juice in filter assembly 10 is forced by centrifugal force to leave filter assembly 10 and flow into vessel 40. In contrast, fruit and vegetable residue will remain in the filter assembly 10.

In order to achieve the above-described juice filtering operation, the filter assembly 10 comprises a base 100 adapted to be coupled to the shaft 20 of the kitchen processor 1. The base 100 is rotatable about an axis a under the drive of the spindle 20. The filter assembly 10 further includes a filter cartridge 200 for filtering juice. The juice can flow out of the filter cartridge 200 under centrifugal force. The filter cartridge 200 is detachably provided to the base 100 to facilitate the user's disassembly for cleaning. The filter cartridge 200 extends in a direction away from the base 100. Finally, the filter assembly 10 further includes a cover 300. The cap 300 extends inwardly from a first edge 211 (not shown in detail herein) of the filter cartridge 200 away from the first end 210 of the base 100. The cover 300 includes an opening. The user may add foodstuff to the filter assembly 10 from the opening. In the embodiment shown in fig. 1, a funnel device 30 is further provided above the cover 300 to facilitate the insertion of food materials by the user. The surface of the cover 300 remote from the base 100 abuts against the surface of the funnel 30. So far, the overall structure of the kitchen processor 1 is introduced, and specific components in the kitchen processor 1 will be described in detail with reference to the drawings, respectively.

Fig. 2 shows a schematic view of a container 40 according to an exemplary embodiment of the present disclosure. As shown in fig. 2, the container 40 is bowl-shaped and includes a spindle hole 41 in the middle of the bottom. The rotation shaft 20 of the kitchen processor 1 is protruded into the container 40 through the rotation shaft hole 41 so that the rotation shaft 20 can be coupled with the base 100 of the filter assembly 10 installed in the container 40.

Fig. 3 shows a schematic diagram of a filter cartridge 200 according to an exemplary embodiment of the present disclosure. As shown in fig. 3, the filter cartridge 200 includes a second end 250 that is proximate to the base 100 and a first end 210 that is distal from the base 100 in an assembled state with the base 100. Filter cartridge 200 further includes a mesh sidewall 220 extending from first end 210 to second end 250, and mesh sidewall 220 extends in a circumferential direction about axis a. Here, the mesh-shaped side wall 220 is, for example, a metal mesh screen.

The first end 210 includes a barrel flange 230. The cartridge flange 230 extends inwardly from the first edge 211 in a third plane parallel to the first plane in which the base of the base 100 lies. A first cover portion 310 continuing to extend inward in an oblique direction is formed at the inner wall of the cartridge flange 230 such that the first cover portion 310 forms a one-piece integral body with the mesh side wall 220, i.e., the first cover portion 310 is fixedly connected with the mesh side wall 220. The first cover part 310 includes a circular opening. Further, a through hole 231 is formed in the cylinder flange 230. In the illustrated embodiment, the cartridge flange 230 includes 4 equally spaced through holes 231 for securing with the base 100.

An inwardly extending protrusion 240 (not shown in detail herein) is provided on the inner wall at the second end 250. In the assembled state, the radial projection 240 extends inwardly from the inner wall at the second end 250 into the chute 131 of the rim of the base 100 to limit movement of the filter cartridge 200 relative to the base 100 in a direction parallel to the axis a.

Fig. 4 shows a schematic view of a base 100 according to an exemplary embodiment of the present disclosure. As shown in fig. 4, the susceptor 100 includes a substrate 110. The base 110 extends in a first plane perpendicular to the axis a. The base 100 also includes a bracket 120. The bracket 120 extends from the base 110 in a direction away from the base and is fixed to the second cover 320 such that the second cover 320 abuts at the first edge 211. In the embodiment shown in fig. 4, the bracket 120 includes 4 support plates 121. The support plates 121 extend from the edge of the base 110 toward the axis a, and 4 support plates 121 are arranged at equal intervals in the circumferential direction around the axis a, that is, each support plate 121 differs by 90 degrees. Here, each radially extending support plate forms a fin for agitating the food material. Thus, the supporting plate 121 not only can provide supporting function, but also can agitate food materials, and the filtering efficiency of fruit and vegetable juice is improved.

The base 100 also includes an outer peripheral surface 130 extending in a circumferential direction about the axis. A chute 131 is provided on the outer peripheral surface 130. The chute 131 comprises a first section extending in a direction parallel to the axis a and a second section extending in a direction perpendicular to said axis a. In this case, when the filter cartridge 200 is mounted on the base 100, the projection 240 of the filter cartridge 200 can enter the first section from the inlet of the slide slot 131 in a direction parallel to the axis a and reach the bottom at which the first section intersects the second section. During rotation of the filter cartridge 200 relative to the base 100, the protrusion 240 moves from the first section into the second section at the intersection of the first section and the second section. The protrusion 240 is constrained in the second section in a direction parallel to the axis a such that movement of the filter cartridge 200 in a direction parallel to the axis a is constrained.

The second cover 320, which is provided at the end of the support plate 121 remote from the base 100, includes a cover flange 321. The cover flange 321 extends inwardly in a second plane parallel to the first plane in which the base 110 lies. A hook stopper 3211 is provided on a surface of the cover flange 321 facing away from the base 110 for connection with the filter cartridge 200.

Fig. 5 shows a schematic diagram of a filter assembly 10 according to an exemplary embodiment of the present disclosure. As shown in fig. 5, the filter cartridge 200 is sleeved outside the base 100. For example, the user lifts the filter cartridge 200 above the base 100, then aligns each through hole 231 on the cartridge flange 230 with the hook-shaped stop 3211 of the cap flange 321 of the second cap 320, and aligns the protrusion 240 of the second end 250 with the first section of the chute 131. After alignment, the user fits the filter cartridge 200 over the base 100 such that the projection 240 enters the first section of the chute 131 and the hook-type stop 3211 passes through the through-hole 231. Meanwhile, the surface of the first cover part 310 facing the base 100 abuts against the surface of the second cover part 320 facing away from the base 100. At this time, the user rotates the filter cartridge 200, for example, in a counterclockwise direction as shown in fig. 5, such that the projection 240 moves into the second section of the chute 131 and the cartridge flange 230 moves under the hook-type stop 3211. Thereby, the filter cartridge 200 is firmly coupled with the base 100. In this way, the filter cartridge 200 can be conveniently and rapidly assembled to the base 100.

Fig. 6 illustrates a cross-sectional view of the filter assembly 10 according to an exemplary embodiment of the present disclosure. As shown in fig. 6, the susceptor 100 includes a substrate 110 extending in a first plane. A coupling portion 140 extending from the base 110 along a distance from the base 110 is provided at the center of the base 110. The coupling portion 140 can be sleeved on the output shaft 20 and cooperate with the output shaft 20 to rotate with the output shaft 20. The support plate 121 extends inwardly from the outer circumferential surface 130 of the base 110, and a radially outward side of the support plate 121 abuts against the mesh-shaped side wall 220 of the filter cartridge 200 to provide support for the mesh-shaped side wall 220. At this time, the projection 240 is in the second section of the chute 131 and abuts against both chute 131. The mesh-shaped sidewall 220 extends from a second end 250 of the filter cartridge 200 near the base 110 to a first end 210 remote from the base 110. At the edge 211 of the first end 210, the second cover 320 extends toward the base 100 in a direction oblique to the axis a, and a cartridge flange 230 is provided at the edge 211. The cartridge flange 230 is overlapped on the cover flange 321 of the second cover 320. The first cap portion 310 (collectively, cap portion 300 with the second cap portion 320) extends from the barrel flange 230 in a direction oblique to the axis a toward the base 100 to form a funnel shape. Further, the hook stopper 3211 of the cover flange 321 protrudes out of the filter cartridge 200 through the through hole 231 of the cartridge flange 230 to restrict movement of the filter cartridge 200 in a direction parallel to the axis a.

The specific structure and implementation principles of the filter assembly of embodiments of the present disclosure have been described in detail above. It will be appreciated that the combined mounting structure of the filter cartridge and base in the filter assembly of the disclosed design can be easily secured without the need for the user to secure the filter cartridge by other means, such as nuts/screws. Furthermore, the filter assembly has an inverted component design, i.e. the filter cartridge is located in the upper part and the plastic cap in the lower part, thereby solving the problem of the cap ejecting during operational rotation.

Although claims have been formulated in this application to particular combinations of features, it should be understood that the scope of the disclosure also includes any novel feature or any novel combination of features disclosed herein either explicitly or implicitly or any generalisation thereof, whether or not it relates to the same in any claim as presently claimed.
