Description

Technical Field

[0001] The present invention relates to a vacuum filter element and a vacuum mixer including the vacuum filter element, wherein the vacuum filter element is disposed between a vacuum chamber and a vacuum pump to filter foreign matter flowing back, so that the foreign matter is stored in the vacuum filter element and clean air can be circulated back to the vacuum pump. Background Technology

[0002] Blenders are among the most commonly used appliances in modern homes, where foods such as fruits, vegetables, and grains are placed in a mixing container and finely pulverized using rotating blades mounted in a rotatable manner in the lower part of the storage container for consumption.

[0003] In a typical blender, the food to be blended is placed in a storage container, the lid is closed, and rotating blades are driven by a high-speed motor. During this process, air in the blending container and the blended food particles are mixed at high speed, generating a large amount of foam.

[0004] When pulverized food is not consumed immediately but needs to be stored, oxidation occurs more rapidly if it is stored in an air-exposed state. This accelerates the breakdown of fiber and nutrients, leading to discoloration and reduced freshness, and causing the air to separate from the food.

[0005] A vacuum blender removes air from the container holding the food to create a vacuum, and then blends the food, thus eliminating oxidation caused by air.

[0006] In conventional vacuum mixers, there is a problem where material fragments, foam, dust (powdered substances), etc., flow back through the vacuum hose during mixing, thus contaminating the vacuum hose or causing vacuum pump malfunction.

[0007] Relevant existing documents include Korean Patent Registration No. 10-2363451 (February 17, 2022) and Korean Patent Registration No. 10-2507566 (March 9, 2023). Summary of the Invention Technical issues

[0037] Details regarding the purpose, technical structure, and resulting operation and effects of the invention will become clearer from the detailed description based on the accompanying drawings.

[0038] The terminology used in this specification is for describing particular embodiments only and is not intended to limit the invention. For example, terms such as “consisting of” or “comprising” as used herein should not be construed as necessarily including all the various components or steps described in the invention, but should be interpreted as possibly excluding some components or steps, or further including additional components or steps. Furthermore, singular expressions used herein include plural expressions unless the context clearly indicates otherwise.

[0039] The present invention will be described in detail below with reference to the accompanying drawings, specifically by describing preferred embodiments thereof. The embodiments described below are provided to enable those skilled in the art to readily understand the spirit of the invention and should not be construed as limiting the invention thereon. It will be apparent to those skilled in the art that the embodiments of the present invention can have various applications.

[0040] Now refer to Figures 1 to 13 A vacuum filter element according to the present invention and a vacuum mixer including the vacuum filter element are described.

[0041] like Figures 1 to 4 As shown, a vacuum mixer 10 according to an embodiment of the present invention may include: a main body 200 equipped with a motor 210 and a vacuum pump 220; a container 20 detachably mounted on the main body 200; a vacuum chamber 135 positioned above the container 20 and configured to draw air from the container 20 to create a vacuum within the container; a vacuum conduit 120 including vacuum hoses 141 and 142 through which air drawn from the vacuum chamber 135 passes; a soundproof enclosure 110 surrounding the container 20 to prevent noise and containing the vacuum conduit 120 and the vacuum chamber 135; and a vacuum filter element 150 detachably disposed within the vacuum conduit 120.

[0042] At this time, the vacuum filter element 150 is placed between the vacuum chamber 135 and the vacuum pump 220 to filter the foreign objects flowing back, store the foreign objects in the container of the vacuum filter element, and allow air to circulate back to the vacuum pump 220.

[0043] Furthermore, according to one aspect of the invention, the vacuum pipe 120 of the vacuum mixer may include a first hose 141 and a second hose 142. With the vacuum filter element 150 as a reference point, one end of the first hose is connected to the vacuum chamber 135 and the other end is connected to the outlet port 151. With the vacuum filter element 150 as a reference point, one end of the second hose is connected to the connection hole 145 and the other end is connected to the inlet port 152.

[0044] Therefore, the vacuum mixer 10 can draw air from the container 20 containing the food to create a vacuum state, and then perform mixing, thereby eliminating oxidation caused by air.

[0045] Furthermore, by providing a vacuum filter element 150 between the vacuum chamber 135 and the vacuum pump 220, foreign matter such as material fragments, foam, and dust (powdered substances) that flow back through the vacuum hose during mixing by the vacuum mixer can be filtered out. The foreign matter can be stored in the container of the vacuum filter element, and clean air can be circulated back to the vacuum pump 220.

[0046] In addition, refer to Figures 5 to 7 In a vacuum mixer 10 according to one aspect of the invention, a vacuum conduit 120 has a protrusion 123 on its inner surface and a connecting space 125 is formed at the lower end 124 of the protrusion 123, so that a vacuum filter element 150 can be connected to the vacuum conduit. The vacuum conduit 120 may include a first support portion 121 and a second support portion 122. The upper portion of the vacuum filter element 150 is connected to and supported by the first support portion, and the lower portion of the vacuum filter element 150 is seated on and supported by the second support portion.

[0047] Furthermore, according to one aspect of the invention, the first support portion 121 of the vacuum pipe 120 is connected by a connecting protrusion and a connecting groove, and the second support portion 122 of the vacuum pipe 120 can be connected by a sliding structure.

[0048] Furthermore, the first support portion 121 can be configured to be connected by the magnetic force of a magnet, and of course, it can be configured to be connected by a hook so that it can be disassembled by tension.

[0049] In addition, the second support portion 122 may be configured to have a stepped portion, so that the vacuum filter element 150 is seated and held therein.

[0050] In addition, refer to Figures 8 to 10 In a vacuum mixer 10 according to one aspect of the invention, the other end of the first hose 141 and the other end of the second hose 142 may be connected to the upper portion of the vacuum filter element 150.

[0051] Therefore, a receiving space capable of receiving a predetermined amount of foreign matter can be provided in the lower part of the container of the vacuum filter element 150, and a first hole 151 and a second hole 152 for connecting the first hose 141 and the second hose 142 can be provided in its upper part.

[0052] Referring to the airflow of the vacuum filter element, when the vacuum pump 220 starts to generate a vacuum, the space inside the container 20 is drawn from the vacuum chamber 135 to form a vacuum, and the air drawn into the vacuum chamber 135 passes through the first hose 141 and moves into the container of the vacuum filter element 150 through the outlet port 151.

[0053] At this time, the air flow speed and pressure are reduced by the ribs 155a of the vacuum filter element 150, foreign objects and inflowing materials fall to the bottom of the lower part of the container, and clean air is drawn in through the inlet port 152 and moves to the vacuum pump 220 through the second hose 142 and the connection hole 145.

[0054] In addition, refer to Figures 11 to 13 According to another aspect of the invention, the vacuum filter element 150 may include: a container 158 having a receiving space for receiving foreign objects; a cover 155 formed at the upper portion of the container to seal the receiving space of the container; and a seal 154 disposed on the cover 155 to seal the space between the container and the cover and to create a complete vacuum between them.

[0055] Furthermore, a first hole 151 and a second hole 152 are formed in the side wall of the container 158, the other end of the first hose 141 is installed in the first hole, and the other end of the second hose 142 is installed in the second hole, so that the inlet port and the outlet port can be inserted into its interior.

[0056] In addition, the first hole 151 and the second hole 152 of the vacuum filter element 150 can be formed on the upper side of the container 158.

[0057] Therefore, a receiving space capable of receiving a predetermined amount of foreign matter can be provided in the lower part of the container of the vacuum filter element 150, and the first hose 141 and the second hose 142 can be connected to its upper part so that clean air can pass through it.

[0058] In addition, a fixing portion 150c protrudes from the outer side of the side wall of the container 158 of the vacuum filter element 150, and the side wall of the container 158 may include an anti-detachment portion 153, which is connected to the cover 155 and fixed to the fixing portion 150c to prevent the cover 155 from detaching from the container.

[0059] Therefore, the lid 155 can be easily removed from the container 158 while being prevented from being separated, lost, or damaged.

[0060] In addition, the anti-detachment part 153 can be formed and connected in the shape of a rope made of elastic material, thereby facilitating the opening and closing of the lid and the cleaning of the inside of the container.

[0061] In addition, the vacuum filter element 150 may have ribs 155a on the cover 155 to form a flow guide path for reducing the flow velocity and pressure of air discharged or drawn in at the outlet port of the first hole 151 and the inlet port of the second hole 152.

[0062] Furthermore, the vacuum filter element 150 can be configured such that ribs 155a are disposed inside the container 158 to form a flow guide path for reducing the flow velocity and pressure of air discharged or drawn in at the outlet port of the first hole 151 and the inlet port of the second hole 152.

[0063] Furthermore, the rib 155a connected to the vacuum filter element 150 protrudes downward from the cover 155 and blocks the flow velocity space for air to be drawn in or discharged through the inlet port and the outlet port, thereby preventing air discharged directly through the outlet port from flowing to the inlet port.

[0064] In other words, rib 155a may have the same shape as the upper inner surface of container 158 (e.g., a rectangular column shape), and rib 155a may extend downward to cover the inlet port and outlet port.

[0065] Therefore, rib 155a blocks the air flow directly from the outlet port to the inlet port, thereby preventing foreign objects from moving directly from the outlet port to the inlet port and preventing contamination of the vacuum hose or malfunction of the vacuum pump.

[0066] In addition, the container 158 of the vacuum filter element 150 may include a connecting portion 150a and a retaining shoulder 150b. The connecting portion is disposed on the side of the container for connection to the vacuum pipe 120 of the vacuum mixer, and the retaining shoulder is disposed at the lower part of the container for sitting on the vacuum pipe.

[0067] In addition, the vacuum filter element 150 may be equipped with a water level sensor (not shown) in the container 158 to detect the accumulation of a predetermined amount of foreign matter or incoming material, and may generate a warning sound or stop the operation of the main body.

[0068] In addition, the vacuum filter element 150 may be equipped with a vacuum sensor (not shown) in the container 158, and when a predetermined amount of foreign matter and / or inflow material has entered and the pressure value measured by the vacuum sensor falls outside the predetermined range, the vacuum filter element 150 may generate a warning sound or stop the operation of the main body.

[0069] When cleaning the vacuum filter element, remove the vacuum filter element 150 installed in the vacuum pipe 120 and open the cover 155 of the removed vacuum filter element 150 to pour out and clean foreign objects and inflowing materials.

[0070] The cover 155 of the vacuum filter element 150 to be cleaned is closed, and the vacuum filter element 150 is installed in the vacuum pipe 120 so that it can be operated again.

[0071] Therefore, the vacuum filter element for receiving foreign objects according to the present invention is easy to disassemble from the vacuum mixer and easy to clean.

[0072] The embodiments described above are provided to enable those skilled in the art to readily understand the technical spirit of the invention and should not be construed as limiting the invention. It will be apparent to those skilled in the art that various modifications and changes can be made to the embodiments of the invention without departing from the spirit and scope of the invention. Therefore, such modifications and variations should be considered to fall within the scope of the claims of the invention.
