Description

FIELD OF TECHNOLOGY

Embodiments of the present invention generally relate to household appliances, and more specifically to a filter and a vacuum food processor containing a filter.

BACKGROUND OF THE INVENTION

The vacuum food processor for blending or chopping is becoming a popular kitchen appliance. A kitchen appliance of this type is usually equipped with a vacuum module, which consists of several components, such as an electric pump, pipes, control electronics, pressure sensors. A traditional problem with such a kitchen appliance is the possible contamination of the vacuum module caused by suction of liquid, steam and food particles moving along with the intake air flow. Such contamination will result in poor performance and even damage to the instrument.

The traditional approach to preventing food particles/bubbles from entering the vacuum module is to create a filter configuration upstream or on the vacuum module inlet. As proposed in CN 206213940 U, a filter containing an opening is used to stop food particles. However, such a simple filter would reduce vacuum efficiency and increase noise, especially when the filter hole(s) is (are) small.

WO 2016072203 A1 proposes a mechanism to better prevent food particles/bubbles from entering the vacuum module. However, this mechanism requires a complex design. In addition, if a large amount of food particles/bubbles are sucked in and trapped, the intake air flow may also be blocked. CN 106724947 A proposes another mechanism for blocking foreign particles, which also requires a complex design.

DISCLOSURE OF THE INVENTION

To prevent food particles/bubbles from entering the vacuum module in a simple and reliable manner, embodiments of the present invention provide a filter for use in a vacuum food processor and a vacuum food processor containing the filter.

In a first aspect, a filter is provided for use in a vacuum food processor. The filter comprises: a first filter part configured to direct an intake air flow generated by the vacuum module of the vacuum food processor into the filter through an inlet port; and a second filter part configured to coaxially mate with the first filter part and containing a cavity, wherein the inner surface of the cavity is configured to hold a non-gaseous substance that moves with the intake air flow inside the filter, wherein the first filter part and the second filter part together form an outlet channel in the lower part of the first part of the filter, and the outlet channel is configured to direct the intake air flow outside the filter.

It should be noted that according to embodiments of the present invention, if some food particles/bubbles enter the filter through the inlet port, the food particles/bubbles can be effectively captured on the inner surface of the second part of the filter, while allowing the intake air flow to exit the filter through a downstream outlet channel formed at the bottom of the filter and subsequently fed or drawn into the vacuum module, for example through a gas channel in communication with the filter. In this way, food particles/bubbles can be spatially separated from the intake air flow in a simple and reliable manner. In addition, such a filter has a simple design, which facilitates manufacturing and, in turn, reduces the overall cost.

In some embodiments, the first filter part comprises a first rib extending in the circumferential direction and oriented in the axial direction of the filter, and the second filter part comprises a second rib extending in the circumferential direction and oriented in the axial direction, wherein when the first rib and the second rib mated with each other, they form a first gap as the first part of the outlet channel.

In some embodiments, when the first rib and the second rib are mating with each other, the first rib is separated from the second rib by a first offset in the radial direction and/or a second offset in the axial direction.

By arranging and mating the two fins, a first barrier can be formed to prevent food particles/bubbles from entering the outlet duct, while the first air gap formed as part of the outlet duct allows intake air to flow through.

In some embodiments, the implementation of the first part of the filter also contains a third rib, oriented in the axial direction and located coaxially with the first rib, and the third rib is made outside the first rib in the radial direction; and the second filter part also includes a fourth rib oriented in the axial direction and located coaxially with the second rib, and the fourth rib is made outside the second rib in the radial direction, while when the second filter part is mated with the first filter part, the third rib and the fourth rib form the second gap as the second part of the outlet channel.

In some embodiments, when the third rib and the fourth rib are mated with each other, the third rib is separated from the fourth rib by a third offset in the radial direction and/or a fourth offset in the axial direction.

By placing and mating an additional two ribs, a second barrier is formed to ensure that a small (or very small) amount of food particles/bubbles that can cross the first barrier does not enter the vacuum module. Meanwhile, the second air gap, as another part of the exhaust port, still allows the intake air flow to pass.

In some embodiments, the first rib is integral with the first filter part and the second rib is integral with the second filter part. In some embodiments, the third rib is integral with the first filter part and the fourth rib is integral with the second filter part. Thus, fewer individual components are required, which facilitates fabrication and assembly.

In some embodiments, when the second filter part is mating with the first filter part, the second fin is downstream of the first fin along the intake air flow direction, the third fin is downstream of the second fin along the intake air flow direction, and the fourth fin is downstream. downstream relative to the third rib along the intake air flow direction.

With such a relative arrangement and appropriate engagement between the plurality of ribs, a tortuous shaped outlet channel composed of a plurality of gaps can be formed, which provides an effective blocking effect for food particles/bubbles.

In some embodiments, the implementation of the first part of the filter contains the first rib, and the first rib extends in the direction along the circumference and has a first end surface perpendicular to the axial direction of the filter; and the second part of the filter contains a second end surface perpendicular to the axial direction, and when the first part of the filter is mated with the second part of the filter, the first end surface is in contact with the second end surface in the axial direction, but with a micro-gap between them for the passage of the intake air flow, and the micro-gap forms part of the outlet channel.

In some embodiments, the cavity comprises a first ancillary cavity and a second ancillary cavity surrounding the first ancillary cavity in a circumferential direction, wherein the first ancillary cavity forms a gripping area on the outer surface of the second filter part, and the second ancillary cavity forms an inclined area on the outer surface of the second part filter.

The gripping portion formed on the outer surface of the second part of the filter makes it easier for the operator to grip from the outside, which in turn facilitates assembly and adjustment. In addition, the second auxiliary cavity expands the internal space to trap food particles/bubbles.

In some embodiments, the first filter part includes a mounting grip and the second filter part includes a mounting hole configured to receive a mounting grip for mating the second filter part with the first filter part. Thus, the two parts of the filter can be attached to each other in a simple and secure manner.

In some embodiments, the first filter part comprises a connecting part configured to releasably pivot the first filter part to the vacuum food processor cover in the radial direction. Thus, the filter can be rotatably attached to the lid of the vacuum food processor and easily detached from the lid for cleaning and maintenance.

In some embodiments, the first filter part includes a pin and the second filter part includes a slot configured to receive the pin to prevent rotation of the second filter part relative to the first filter part in a circumferential direction.

Thus, the rotation of the second filter part with respect to the first filter part can be prevented, thereby enabling secure installation. In addition, the pin and slot can provide the operator with a convenient indication for the precise placement of the second filter part relative to the first filter part during installation.

In some embodiments, the first rib is configured to support the second filter part when the second filter part is mated with the first filter part, wherein the first rib has a contact surface facing towards the inner surface of the cavity, and the contact surface is configured to align with the inner surface of the inclined site. In this way, a more stable and reliable holding effect as well as a better sealing effect can be achieved.

In some embodiments, the implementation of the first part of the filter may contain a handle. The handle can provide the operator with convenient holding and opening of the filter.

In a second aspect, a vacuum food processor is provided. The vacuum food processor comprises a filter according to the first aspect of the present invention.

It will be apparent from the following discussion that, compared to conventional vacuum food processors, the vacuum food processor incorporating the filter according to various embodiments of the present invention prevents the vacuum module from being contaminated by liquid, steam, food particles sucked in with the intake air stream. However, due to the less complex design, the overall cost of the device is reduced and the fabrication/assembly is simplified.

IMPLEMENTATION OF THE INVENTION

The principles of the present invention will now be described with reference to several exemplary embodiments shown in the drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the embodiments are described only to assist those skilled in the art to better understand and thus practice the present invention, and not to limit the scope of the invention in any way.

During the vacuum process performed by the vacuum food processor, the vacuum module sucks air from the container unit containing the food to form an intake air stream. Sometimes there are liquids, food particles or steam moving along with the intake air flow due to the high vacuum pressure in the range of -70 kPa to -80 kPa. In order to avoid suction of these liquids or food particles directly into the vacuum module, which consists of an electric pump, tubes, control electronics, pressure sensors, etc., a filter is proposed to trap these liquids, food particles and vapors.

In FIG. 1A is a cross-sectional view of a filter for use in a vacuum food processor according to an embodiment of the present invention. In FIG. 1B shows a simplified cross-sectional view of the filter of FIG. 1A. In FIG. 1B, for clarity, some profile lines from different surfaces/planes are intentionally removed to avoid unnecessary confusion and at the same time highlight the cavity. In FIG. 1C shows another cross-sectional view of the filter which is perpendicular to the cross-sectional view shown in FIG. 1A.

As shown, the filter 10 includes a first filter part 1 and a second filter part 2. The first filter portion 1 is configured to direct the intake air stream 20 generated by the vacuum module of the vacuum food processor into the filter 10 through the inlet 105. In some embodiments, as shown in FIG. 1A, inlet 105 may be in the form of a plurality of holes.

In addition, the second filter part 2 is configured to coaxially mate with the first filter part 1 and contains a cavity 4. The inner surface of the cavity 4 is configured to hold a non-gaseous substance (such as liquid, vapor or food particles) that moves along with the suction flow 20 air inside the filter 10. In addition, as shown in FIG. 1A, the first filter part 1 and the second filter part 2 together form an outlet 3 in the lower part 106 of the first filter part 1. The outlet channel 3 is configured to direct the intake air flow 20 outside the filter 10.

With this design of the filter 10, when some food particles/bubbles enter the filter through the inlet port 105, the food particles/bubbles can be effectively captured on the inner surface of the second filter part 2 while the intake air flow 20 is still allowed to exit the filter. 10 through a downstream outlet 3 formed at the bottom 106 of the filter 10 and subsequently fed or drawn into the vacuum module, for example through a gas duct in communication with the filter 10.

In this way, food particles/bubbles can be spatially separated from the intake air flow in a simple manner. In addition, compared to some conventional designs, filter 10 according to various embodiments of the invention requires fewer individual components and does not require a complex design, which facilitates manufacture and, in turn, reduces overall manufacturing and maintenance costs.

In some embodiments, as shown in FIG. 1A, the first filter part 1 may include a first rib 101, the first rib 101 extending in the C direction along the circumference and extending in the Y-axial direction of the filter 10 to a certain height to protrude from the bottom of the first filter part 1. In addition, the second filter part 2 may include a second rib 202 extending in the C direction along the circumference in the same manner as the first rib 101 and extending in the Y-axial direction to a certain height to protrude from the second filter part 2. As also illustrated in FIG. 1A, when the first rib 101 and the second rib 202 are mated with each other, they can form the first gap 31 as the first part of the outlet 3.

In some embodiments, when the first rib 101 and the second rib 202 are mating with each other, the first rib 101 is separated from the second rib 202 by a first offset in the radial direction R and a second offset in the axial direction Y. Thus, a curved first air gap can be formed. 31. Offset in the radial direction means that the protrusions of the two ribs in the radial direction are not aligned with each other. Due to the thickness of the ribs, the lack of alignment of their protrusions with each other in the radial direction includes complete misalignment or partial misalignment. When offset in the axial direction, it is assumed that the distal ends at which the two ribs extend in the axial direction (ie, the protrusions of the tips of the first rib and the second rib) do not overlap each other in the axial direction. When assembled, the tip of the first rib is the uppermost end of the first rib and the tip of the second rib is the lowermost end of the second rib. The first gap 31 is formed when the uppermost end of the first rib is lower than the lowermost end of the second rib. By making the gap 31 small enough, the non-gas phase or impurities can be blocked from passing through the gap 31. When the first fin and the second fin are offset in the radial direction, the highest end of the first fin can be higher than the lowest end of the second fin, and then a tortuous airflow channel. This is preferred for blocking non-gas phases or impurities.

With this placement and mating of the two fins, a first barrier can be formed to prevent food particles/bubbles from entering the outlet channel 3, while the first air gap 31 formed as part of the outlet channel 3 allows the intake air flow 20 to pass through.

In some embodiments, the first rib 101 and the second rib 202 may be integrally molded with the first filter part 1 and the second filter part 2, respectively, by extrusion and injection molding, for example. Thus, fewer individual components are required, which reduces manufacturing and assembly complexity.

In some embodiments, as shown in FIG. 1A, the first filter part 1 may further comprise a third rib 103 protruding in the Y-axial direction and coaxial with the first rib 101, and the second filter part 2 may further include a fourth rib 204 protruding in the Y-axial direction and coaxial with the second rib 202. In addition, the third rib 3 may be provided outside the first rib 101 in the radial direction R, and the fourth rib 204 may be provided outside the second rib 202 in the radial direction R. Further, as shown in FIG. 1A, when the second filter part 2 is mated with the first filter part 1, the third rib 103 and the fourth rib 204 form a second gap 32 as the second part of the outlet 3.

In some embodiments, when the third rib 103 and the fourth rib 204 are mating with each other, the third rib 103 is separated from the fourth rib 204 by a third offset in the radial direction R, and a fourth offset in the axial direction Y. Thus, a curved second air gap 32.

With this placement and mating of the additional two ribs, a second barrier is formed to ensure that a small (or very small) amount of food particles/bubbles that can cross the first barrier do not enter the vacuum module. Meanwhile, the second air gap 32, as another part of the outlet channel 3, still allows the intake air stream 20 to pass into and out of the cavity 4 and then be fed or sucked into the vacuum module, for example, through a gas channel in communication with filter 10.

Similarly, in some embodiments, the third rib 103 and the fourth rib 204 may be integrally molded with the first filter part 1 and the second filter part 2, respectively, by extrusion and injection molding, for example, to facilitate fabrication and assembly.

In the example shown in FIG. 1A with respect to the direction of the intake air flow 20, the second fin 202 is located downstream of the first fin 101, the third fin 103 is located downstream of the second fin 202, and the fourth fin 204 is located downstream of the third fin 103.

With this relative arrangement and appropriate engagement between the plurality of ribs of the first and second parts of the filter, a tortuous shaped outlet 3 is formed, consisting of a plurality of gaps, which provides a more effective blocking of food particles/bubbles. In other words, it becomes more difficult for food particles/bubbles to reach the vacuum module.

In addition, it should be noted that in some embodiments, the sinuously shaped radial outlet 3 also forms an annular shape in the C direction along the circumference, which greatly expands the range in which the intake air stream 20 can be discharged from the cavity 4. In other words, a spatial outlet is formed. channel 3. Thus, even if the outlet channel 3 is clogged with some food particles/bubbles at a certain location in the circumferential direction C, the airflow 20 can still exit from other locations without interference. This improves the safety and stability of the filter 10.

In some alternative embodiments, the first filter part 1 may comprise a first rib 101 as shown in FIG. 1A having a first end surface perpendicular to the Y-axial direction of the filter 10. However, the second filter 2 may not have a second rib, preferably only the second filter part 2 has a second end surface perpendicular to the Y-axial direction. In such a case where the first filter part 1 is conjugate with the second filter part 2 along the Y-axial direction, the first end surface of the first rib 101 is in contact with the second end surface of the second filter part 2 in the Y-axial direction. In other words, the second filter part 2 is supported by the first filter part in the Y-axial direction by contact between the first end surface and the second end surface.

Thus, a micro gap can still be formed between the first and second end surfaces for the passage of the intake air flow 20 . The micro-gap forms part of the outlet port 3, allowing only the air flow to pass through, while effectively blocking bubbles or impurities.

Again with reference to FIG. 1A, in some embodiments, the first filter part 1 may include a connecting part 108 configured to releasably swivel the first filter part 1 to the lid of the vacuum food processor in the radial direction R. Thus, the filter can be rotatably attached to the lid of the vacuum food processor. harvester and is easily detached from the cover for cleaning and maintenance. In some embodiments, the first filter portion 1 may include a handle 104 to allow the operator to conveniently hold and open the filter 10.

In FIG. 2A and 2B show a bottom view and a top view of a second filter portion, respectively, for a filter according to an embodiment of the present invention. As shown in FIG. 2A, the cavity 4 may include a first ancillary cavity 41 and a second ancillary cavity 42 surrounding the first ancillary cavity 41 in the circumferential direction C. In addition, as shown in FIG. 2B, the first auxiliary cavity 41 defines a gripping portion 205 on the outer surface 200 of the second filter part 2, and the second auxiliary cavity 42 defines an inclined portion 206 on the outer surface 200 of the second filter part 2.

The grip portion 205 formed on the outer surface 200 of the second filter part 2 makes it easier for the operator to grip from the outside, which in turn facilitates assembly and adjustment. In addition, the second auxiliary cavity 42 expands the internal space for trapping food particles/bubbles. This is particularly advantageous if there is a large amount of food particles/bubbles generated.

In some embodiments, the first ancillary cavity 41 and the second ancillary cavity 42 (as well as the grip portion 205 and the slant portion 206) may be formed by, for example, extrusion and injection molding to facilitate manufacturing and increase the overall stiffness of the filter portion.

In FIG. 3 is a perspective view of a first filter part for a filter according to an embodiment of the present invention. As shown in FIG. 3, in some embodiments, the first filter part 1 may include a mounting grip 107. As shown in FIG. 2A, the second filter part 2 may include a corresponding mounting hole 208 configured to receive a mounting grip 107 for mating the second filter part 2 with the first filter part 1. Thus, the two parts of the filter can be attached to each other in a simple and secure manner.

Again with reference to FIG. 2A and 3, in some embodiments, the first filter part 1 may include a pin 109 and the second filter part 2 may include a slot 209 configured to receive a pin 109 to prevent the second filter part 2 from rotating relative to the first filter part 1 in the circumferential direction C. .

Thus, rotation of the second filter part 2 with respect to the first filter part 1 can be prevented, thereby enabling secure installation. In addition, pin 109 and slot 209 can provide an operator with a convenient indication for the precise placement of the second filter part 2 relative to the first filter part 1.

In some embodiments, the first rib 101 is configured to support the second filter part 2 when the second filter part 2 is mated with the first filter part 1, as shown in FIG. 1. In addition, the first rib 101 may include a contact surface facing the direction of the inner surface of the cavity 4, and the contact surface is configured to be aligned with the inner surface of the inclined portion 206. As a result, the profile of the first rib 101 follows the profile of the inner surface of the second part 2 filter, more stable and reliable maintenance can be achieved. In some embodiments, the second filter part 2 may be configured to lift slightly in the axial Y direction relative to the first filter part 1 under vacuum airflow to open the outlet 3.

In FIG. 4 shows a filter 10 hinged to the lid 30 of a vacuum food processor according to an embodiment of the present invention. As discussed above, the filter 10 can be rotatably attached to the lid 30 of the vacuum food processor using the fitting 108 and easily detached from the lid 30 for cleaning and maintenance.

It should be understood that the above detailed embodiments of the present disclosure are only intended to illustrate or explain the principles of the present disclosure, and not to limit the present disclosure. Therefore, any modifications, equivalent alternatives and improvements, etc., that do not depart from the spirit and scope of this disclosure should be included within the protection scope of this disclosure.
