Description

Vacuum mixer with food backflow prevention function {VACUUM BLENDER WITH FUNCTION OF PREVENTING OVERFLOWING}

The present invention relates to a vacuum mixer having a food backflow prevention function, and more particularly, to a function of preventing backflow of food microparticles stored in a storage container of a vacuum mixer into a vacuum mixer body during a vacuum or grinding process. Relates to a vacuum mixer.

The blender is one of the most popular electrical appliances in the home today, and it uses a blender blade rotatably installed under the storage container to crush and eat fruits, vegetables and grains.

In general, the blender rotates the mixer blade by a high speed motor which closes the lid after inserting the food to be crushed into the storage container. In this process, a lot of bubbles are generated as the air in the storage container is mixed with the crushed food grains at high speed. . For example, when a fruit, such as a banana or tomato, is put in a blender and crushed, a large amount of bubbles are generated at the top of the fruit juice. This not only lowers the taste and texture of drinking fruit juice, but also means that the fruit fiber has already been oxidized in the grinding process, resulting in significant destruction of nutrients.

In addition, if the food should be stored without being consumed immediately after crushing, if it is stored in the air, the oxidation process will be accelerated faster, the destruction of fiber and nutrients will be accelerated, the color will be discolored, and the freshness will be reduced. Layer separation occurs between the food and the ingredients. As such, the ingredients ground by the blender have a problem that it is difficult to store them for a long time unless they are eaten immediately.

In order to solve this problem, a vacuum mixer designed to grind food materials in a vacuum state has been developed. The vacuum mixer developed by the present inventor is disclosed in Korean Patent Application Publication No. 2015-0145163 (name of the invention: a vacuum mixer and a method of operating the same) (Patent Document 1). This vacuum mixer comprises a main body provided with an internal space; A mechanical operating part including a vacuum pump and a rotating motor installed in an inner space of the main body; A support configured to pass through the vacuum tube connected to the vacuum pump and to rise from the machine operation by a predetermined height; A first vacuum chamber is provided above the support and connected to the vacuum tube.

It includes; a vacuum processing unit consisting of a sealing cover installed to selectively open and close the check valve to the sealing connection portion.

By using the vacuum mixer configured in this way, the convenience of use is improved by integrating the vacuum apparatus in the main body of the mixer, and the vacuum container can be dualized to separate / store the storage container while maintaining the vacuum state.

However, as a result of actual use of the vacuum mixer, a problem arises in that the liquid flows through the check valve attached to the sealing cover of the storage container while foaming in the liquid phase while the liquid food such as milk is put into the storage container and the vacuum is removed. Found. When food fines such as bubbles flow back out of the storage container, the vacuum tube flows into the electric parts such as the vacuum motor, and in some cases, the vacuum motor and the vacuum sensing sensor fail. Therefore, in order to expand the use of the vacuum mixer, there is a demand for the development of an effective method capable of preventing the backflow of food fines in the storage container during the vacuum generation.

The vacuum mixer 100 in which the storage container 510 of the present invention is used has a machine operating part 200 in which mechanical parts for vacuum and crushing are built, and extends from the machine operating part 200 to a constant height to the above. The storage container 510 extends horizontally from the first support part 300 and the second support part 301 and the first support part 300 to provide a space in which the storage container 510 can be seated on the machine operation part 200. A vacuum decompression unit 400 provided with a configuration for vacuum decompression, a storage container 510 seated on the machine operation part 200 and having a second vacuum chamber formed therein and provided with a grinder such as a blade; The vacuum is composed of a sealing cover 520 that is sealably covered on the 510 and installed to selectively open and close the check valve 530 at a portion sealingly connected to the lower portion of the first vacuum chamber 450 of the vacuum decompression unit 400. It includes a processing unit 500.

The machine operation unit 200 is provided with a main body 210 having an internal space, a vacuum pump (not shown) and a rotating motor (not shown) installed in the internal space of the main body 210. The main body 210 may be installed so that the operation button 220 and the power button 221 which are operated by the user to perform various functions are exposed to the outside of the main body. In addition, the upper surface of the main body 210 is provided with a seating surface so that the storage container 510 can be placed in conjunction with the mechanical operation unit 200. A vacuum tube 320 is connected to the vacuum pump, and the vacuum tube 320 is installed to extend through the interior of the first support part 300 to the vacuum decompression unit 400.

The operation method of the vacuum mixer configured as described above will be briefly described with reference to FIG. 6 as follows. First, the storage container 510 according to the invention is mounted on the main body 210 of the vacuum mixer 100. Thereafter, when the vacuum decompression unit 400 is rotated horizontally around the upper end of the first support unit 300, one end of the vacuum decompression unit 400 is fixedly coupled to the second support unit 301. The vacuum chamber 450 communicating with the vacuum tube 320 and the connection nozzle 440 is formed in the body 410 of the vacuum decompression unit 400. Upper and lower portions of the vacuum chamber 450 communicate with the outside of the body 410, and the upper portion of the vacuum chamber 450 is configured to be selectively opened and closed by a vacuum stopper 430 mounted in the receiving groove 420. . The lower part of the vacuum chamber 450 is in close contact with the upper surface of the sealing cover 520 in which the check valve 530 is installed by the pressure reducing part packing so that the vacuum chamber 450 may be kept in a sealed state. The vacuum state of the vacuum chamber 450 may be released by the user simply by lifting the vacuum stopper 430.

The user operates the vacuum pump (not shown) by pressing the operation button 220 of the machine operation part 200 after the vacuum decompression unit 300 is mounted on the storage container 510 to form the vacuum chamber 450. When the vacuum pump is operated, the vacuum tube 320, the connection nozzle 440, the vacuum chamber 450, and the storage container 510 constituting one air passage are in a vacuum state. Since the check valve 530 of the sealing cover 520 allows only air to be discharged from the inside of the storage container 510 to the outside and prevents the air from flowing into the inside of the storage container 510, The operation of the vacuum pump serves to maintain the vacuum after the interior space 515 of the storage container 510 is in a vacuum state.

Thereafter, the user may manipulate the operation button 220 of the machine operation unit 200 to process the food material stored in the storage container 510, or may form a vacuum again to store the processed food material. At this time, a phenomenon in which the food fine material stored in the storage container 510 rises and flows back through the check valve 530 installed in the sealing cover 520. The refluxed food fines may enter the inside of the vacuum pump through the vacuum tube 320 and cause the vacuum pump to fail. The present invention is to install two kinds of backflow prevention means (backflow prevention cap, backflow prevention filter) inside the vacuum mixer to prevent backflow of the food material fine particles, each of the backflow prevention means will be described in detail below. .

First, the configuration of the backflow prevention cap according to the present invention will be described in detail with reference to FIGS.

Backflow prevention cap 600 according to the present invention, the main body 210; A mechanical operating part 200 including a vacuum pump and a rotating motor installed in an inner space of the main body; A vacuum decompression unit 400 communicating with a vacuum tube 320 connected to the vacuum pump to form a first vacuum chamber 450; And a storage container 510 seated on the machine operation part 200 and having a second vacuum chamber formed therein, and sealingly covered on the storage container 510 to be sealable on the storage container 510. In the vacuum mixer 100 comprising a; vacuum processing unit consisting of a sealing cover 520 is installed to selectively open and close the check valve 530 in a portion that is sealingly connected to the lower portion of the 450,

Installed in the lower portion of the sealing cover 520 in the storage container 510, and forms a disc body including a hollow portion and a border plate 650 surrounding the hollow portion, the disc of the disc body The edge plate 650 has a constant curvature and is configured to have an arc shape convex upward.

The edge plate 650 having the upper convex arc shape configured as described above is a food material stored in the storage container 510 during vacuum or processing in a state of being installed under the sealing cover 520 as shown in FIG. 6. Even if the fines of the spring bounces upwards by the rotational force to fall back down the storage container 510 along the arc-shaped curved surface of the edge plate 650 to prevent the fines of the food material to flow back out of the sealing cover Prevent it.

To have a convex arc shape upward along the rim of the backflow prevention cap 600 is to put the ingredients inside the vacuum mixer when processing the food microstructures crushed by the centrifugal force generated by the strong rotation of the blade This is because it climbs up the wall of 510.

In addition, the backflow prevention cap 600 has a center plate 610 is formed in the hollow portion of the disc-shaped body, the center plate 610 is the edge plate 650 via one or more connecting bars 640. The first air passage 660 may be formed between the center plate 610 and the edge plate 650. The first air passage 660 may be formed in the same line as the disc-shaped body which is formed horizontally, and forms a bypass path through which air escapes together with the second air passage 630 which will be described later.

In addition, a plurality of air distribution holes 611 may be formed in the center plate 610. This air distribution hole 611 can form a straight path through which air escapes. In addition, the upper portion of the center plate 610, a coupling cylinder 620 is formed so as to be spaced apart by a predetermined interval by the connecting bar 640, a second between the center plate 610 and the coupling cylinder 620. An air passage 630 may be formed. The second air passage 630 may be formed on the same line as the vertical wall of the coupling cylinder 620, and forms a bypass path through which air escapes together with the first air passage 660 described above.

As described above, the operation of the straight path (air distribution hole) and the bypass path (the first air passage and the second air passage) formed around the center plate 610 will be described in detail with reference to FIG. 8.

It is preferable that the center plate 610 has a constant curvature similar to the edge plate 650 and has an upper convex arc shape. As described above, during the processing of the food material, the food fine material mainly rises separately from the wall surface of the storage container 510 by centrifugal force generated by the strong rotation of the blade, but some of them collide with each other and the center of the storage container 510. It can also spring up through space. At this time, the arc-shaped center plate 610 is to cause the boiled food material to fall back below the storage container 510 along the arc-shaped curved surface of the center plate 610 so that the fine material of the food material outside the sealing cover To prevent backflow.

In addition, a thread 621 may be formed on the inner circumferential surface of the coupling cylinder 620 so as to be screwed with the lower portion of the sealing cover 520. The coupling cylinder 620 has a space formed therein in a state of being screwed with the sealing cover 520, in which the straight path (air flow hole) and the bypass path formed around the center plate 610 in this space The air flowing through (the first air passage and the second air passage) meet with each other to form a vortex.

7 and 8 is an operational state diagram showing two backflow prevention action of the backflow prevention cap according to the present invention configured as described above.

First, as shown in FIG. 7, the backflow preventing cap 600 is formed in an arc shape in which the edge plate 650 and the center plate 610 are convex upward. Allow it to fall down. Put the ingredients in the storage container, vacuum, and then rotate the blade to grind the ingredients. At this time, since the blade installed in the storage container 510 is rotated at a high speed, the liquid food material pulverized due to the centrifugal force rises on the wall surface of the storage container 510.

If the non-return cap 600 is not installed, some of the food fines will flow out of the storage container 510 through the check valve 530 mounted on the sealing cover 520 by the lifting force. . The spilled food fine material stays in the first vacuum chamber 450 and subsequently flows into the vacuum motor along the vacuum tube 320 to cause a failure when the vacuum operation proceeds.

The backflow prevention cap 600 according to the present invention is installed to be positioned below the sealing cover 520 in the inside of the storage container 510 so that the rising food fines fall back below the storage container 510. As described above, since the centrifugal force through the high-speed rotation of the blade rotates up the wall surface of the storage container 510, most of the food fines are raised toward the outside of the backflow prevention cap 600. Correspondingly, the backflow prevention cap 600 makes the edge plate 650 portion of the edge plate 650 widest and convex upward so that the rising food fines can be lowered again along the curved surface of the edge plate 650.

In addition, some of the rising food fines may bounce upward through the central space of the storage container 510 while colliding with each other. Correspondingly, the backflow prevention cap 600 is manufactured by forming the center plate 610 in a convex shape upward, whereby the food fine particles bouncing toward the center of the storage container 510 are lowered again along the curved surface of the center plate 610. It allows you to.

At this time, the size and curvature of the edge plate 650 and the center plate 610 is determined in consideration of the amount of the food material to be bumped up, it is preferable that the edge plate 650 is wider and the curvature is larger. . This is because, as described above, due to the centrifugal force caused by the high speed rotation of the blade, a large amount of the food fine material rises toward the edge plate 650 on the wall surface of the storage container 510.

8 shows yet another backflow prevention action of the backflow prevention cap 600 according to the present invention. As the vacuum operation proceeds, air rises in the storage container 510 and flows out through the check valve 530 of the sealing cover 520. At this time, the air flows through the two air movement paths formed in the backflow preventing cap 600. Ascending through (A).

First, some air containing food fines is vertically raised through a straight path formed through the air distribution hole 611 formed in the center plate 610. Some other air containing food fines is perpendicular between the first air passage 660 formed horizontally between the center plate 610 and the edge plate 650 and between the center plate 610 and the coupling cylinder 620. Bypass through the bypass path formed by the second air passage 630 is formed to rise.

As such, the air rising through the two air movement paths A meets each other in the inner space of the coupling cylinder 620. At this time, the air that has risen through the two paths meet and collide with each other because the moving angles are different from each other, and as a result, the rising force of the air is weakened for a predetermined time as a vortex is formed. In the meantime, the food fines contained in the air are lowered again under the storage container by gravity action due to the weight thereof (see B path of FIG. 8).

As such, the backflow prevention cap 600 according to the present invention effectively prevents backflow of the food material to the outside of the storage container 510 by the above-described two actions.

The backflow prevention cap 600 according to the present invention may be installed in the present container equipped with a grinder such as a blade as shown in FIG. 3, and the auxiliary container 515 without the grinder as shown in FIG. 9. Can also be installed.

A mesh 730 may be provided on the hollow to prevent backflow into the body of the mixer. The mesh 730 may be made of any one of fiber, metal, and plastic.

The backflow prevention filter 700 may be integrally manufactured by inserting the body 710 and the mesh 730 in which the hollow part is formed, and the mesh support member 720 may cross the hollow part. 710 may be fixedly installed. When the vacuum operation is performed, a considerable pressure is applied to the mesh 730 due to the strong suction force by the vacuum motor. Since the mesh 730 in the form of mesh has little self rigidity, the body is deformed or severely affected by the pressure. It may be dropped from 710. In consideration of this point, the mesh support member 720 is installed to cross the hollow portion to prevent deformation of the mesh 730.
