Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a vacuum mixer,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a vacuum mixer having a function of preventing backflow of a food ingredient, and more particularly, to a vacuum mixer having a function of preventing fine material of foodstuff stored in a vacuum mixer from flowing back into a vacuum mixer To a vacuum mixer.

The blender is one of the most used electrical appliances in the home today, and it can grind fruits and vegetables, grains, and other ingredients finely by using mixer blades that are rotatably installed under the storage container.

In general, the blender inserts food ingredients to be crushed into a storage container, then closes the lid and rotates the mixer blades by a motor rotating at a high speed. In this process, a large amount of bubbles are generated as the air in the storage container and the crushed food ingredients are mixed at high speed . For example, when a fruit such as a banana or a tomato is put into a blender and crushed, a large amount of air bubbles are generated in the upper part of the fruit juice. This not only lowers the taste and texture of the fruit juice, but also means that the fruit fiber has already been oxidized during the grinding process and the nutrients have been largely destroyed.

In addition, if the foodstuff is to be stored without being consumed immediately after it is crushed, if it is stored in an air-exposed state, the oxidation process proceeds more rapidly, the destruction of the fiber and the nutrient is accelerated, the color is discolored, And the separation of the foodstuffs occurs. In this way, the foodstuffs crushed by the blender were difficult to store for a long period of time unless they were eaten immediately.

To solve these problems, a vacuum mixer designed to crush ingredients in a vacuum state has been developed. A vacuum mixer developed by the present inventor is disclosed in Korean Patent Laid-Open Publication No. 2015-0145163 entitled Vacuum Mixer and Its Operation Method (Patent Document 1). The vacuum mixer includes a main body having an inner space; A machine operating portion including a vacuum pump and a rotary motor installed in an internal space of the main body; A vacuum tube connected to the vacuum pump and configured to pass through the inside of the vacuum tube; A first vacuum chamber is formed in the upper portion of the support portion and connected to the vacuum tube, the upper and lower portions of the first vacuum chamber communicate with the outside, and the upper portion of the first vacuum chamber is sealed by a first vacuum stop A vacuum decompression unit configured to selectively open and close; And a mixer blade mounted on the machine operating part and having a second vacuum chamber formed therein, the mixer blade being connected to the rotating motor, and a storage chamber sealed on the storage container, and a lower portion of the first vacuum chamber of the vacuum decompression portion And a vacuum processing part composed of a sealing lid provided so as to selectively open and close a check valve at a sealing connection part.

By using the vacuum mixer thus constructed, the vacuum device can be integrated into the main body of the blender to improve the convenience of use and to separate / store the vacuum container while maintaining the vacuum state.

However, as a result of using the vacuum mixer in practice, it was found that there was a problem that the liquid bubbles are generated while the liquid food material such as milk is put into the storage container and the vacuum is removed, and the liquid flows back through the check valve mounted on the sealing lid of the storage container Found. Bubbles and the like are flowed back to the outside of the storage container, the vacuum tube flows into the inside of the electric parts such as the vacuum motor, and the vacuum motor and the vacuum sensor are broken down in severe cases. Therefore, in order to expand the use of the vacuum mixer, it is required to develop an effective method for preventing the reverse flow of the food fine particles in the storage container when the vacuum is generated.

The vacuum mixer 100 in which the storage container 510 of the present invention is used includes a machine operating part 200 in which a machine part for vacuum and crushing is built in, A first support part 300 and a second support part 301 which provide a space in which the storage container 510 can be seated on the machine operation part 200 and a second support part 300 which extends horizontally from the first support part 300 A storage container 510 mounted on the machine operation part 200 and having a second vacuum chamber formed therein and provided with a crusher such as a blade, And a seal cover 520 which is hermetically covered on the first vacuum chamber 510 and is sealed and connected to the lower portion of the first vacuum chamber 450 of the vacuum depressurization unit 400 to selectively open and close the check valve 530. [ And a processing unit 500.

The machine operating part 200 includes a main body 210 having an internal space and 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 provided with an operation button 220 and a power button 221 which are operated by a user to perform various functions and are exposed to the outside of the main body. In addition, a seating surface is provided at the upper end of the main body 210 so that the storage container 510 can be placed in interlock with the mechanical operation unit 200. The vacuum pump 320 is connected to the vacuum pump 320. The vacuum tube 320 is installed to extend through the interior of the first support part 300 to the vacuum decompression part 400.

A method of operating the vacuum mixer constructed as above will be briefly described with reference to FIG. First, the storage container 510 according to the present invention is placed on the main body 210 of the vacuum mixer 100. Thereafter, when the vacuum decompression unit 400 is horizontally rotated about 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. A vacuum chamber 450 is formed in the body 410 of the vacuum decompression unit 400 to communicate with the vacuum tube 320 through a connection nozzle 440. The upper and lower portions of the vacuum chamber 450 are communicated with the outside of the body 410 and the upper portion of the vacuum chamber 450 is selectively opened and closed by a vacuum cap 430 mounted in the receiving groove 420 . The lower portion of the vacuum chamber 450 is closely attached to the upper surface of the sealing lid 520 provided with the check valve 530 by the depressurized portion packing so that the vacuum chamber 450 can be kept sealed. The vacuum state of the vacuum chamber 450 can be easily released by the user by lifting the vacuum stopper 430.

The user operates the vacuum pump (not shown) by pressing the operation button 220 of the machine operating part 200 after the vacuum decompression part 300 is mounted on the upper part of the storage container 510 and the vacuum chamber 450 is formed. 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. The check valve 530 of the sealing lid 520 allows air to be discharged from the inside of the storage container 510 to the outside and prevents air from being introduced into the inside of the storage container 510 from outside, After the internal space 515 of the storage container 510 is evacuated by the operation of the vacuum pump, the vacuum space maintains the vacuum.

Thereafter, the user may operate the operation buttons 220 of the machine operation unit 200 to process the foodstuff stored in the storage container 510, or may form a vacuum again to store the processed foodstuff. At this time, the fine material of the foodstuff stored in the storage container 510 rises and flows backward through the check valve 530 provided in the sealing lid 520. The refluxed food material fine water may travel through the vacuum tube 320 to reach the inside of the vacuum pump to break the vacuum pump. In the present invention, two backflow prevention means (backflow prevention cap, backflow prevention filter) are provided inside a vacuum mixer to prevent backflow of the fine food material, and each of these backflow prevention means will be described in detail below .

First, the configuration of the backflow preventing cap according to the present invention will be described in detail with reference to FIG. 3 to FIG.

The backflow preventing cap 600 according to the present invention includes a main body 210; A machine operating part 200 including a vacuum pump and a rotary motor installed in an internal 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; A storage container 510 which is seated on the machine operating part 200 and in which a second vacuum chamber is formed, a first vacuum chamber 400 which is hermetically covered on the storage container 510, And a sealing cover 520 installed to selectively open and close the check valve 530 at a portion sealingly connected to a lower portion of the vacuum chamber 450. In the vacuum mixer 100,

The body of the disk-shaped body is installed in the lower part of the sealing lid 520 inside the storage container 510 and includes a hollow part and a frame plate 650 surrounding the hollow part. The frame plate 650 is configured to have a constant curvature and be convex upward in shape.

As shown in FIG. 6, the frame plate 650 having the convex upward convex shape formed in this way is placed in a lower part of the sealing lid 520, The microfluid of the food material flows back to the outside of the sealing lid by allowing the microfluid of the food material to fall down below the storage container 510 along the curved surface of the rim plate 650 It prevents.

The shape of the upper convex arc along the rim of the backflow prevention cap 600 is that when the food material is put into the vacuum mixer and processed, centrifugal force generated by strong rotation of the blade causes the fine material of the crushed food material And rises up on the wall surface of the upper surface 510.

The backflow preventing cap 600 has a center plate 610 formed on the hollow portion of the disc body and the center plate 610 is connected to the edge plate 650 via one or more connecting bars 640. [ So that a first air passage 660 is formed between the center plate 610 and the frame plate 650. The first air passage 660 may be formed in line with the disk-shaped body formed horizontally, and forms a detour path along with the second air passage 630 to be described later.

In addition, a plurality of air flow holes 611 may be formed in the center plate 610. This air flow hole 611 can form a straight path through which the air escapes. An engaging cylinder 620 is formed at an upper portion of the center plate 610 so as to be spaced apart from the connecting bar 640 by a predetermined distance and between the center plate 610 and the engaging cylinder 620, An air passage 630 may be formed. The second air passage 630 may be formed to be in line with the vertical wall of the coupling cylinder 620 to form a detour path along with the first air passage 660.

The operation of the linear path (air circulation hole) and the bypass path (the first air passage and the second air passage) formed around the center plate 610 as described above will be described later in detail with reference to FIG.

It is preferable that the center plate member 610 has a constant curvature and a convex arc shape as in the case of the edge plate member 650. As described above, during the processing of the foodstuff, the fine material of the food material mainly rises up the wall surface of the storage container 510 due to the centrifugal force generated by the strong rotation of the blade, but some of them collide with each other, You can also jump up through space. At this time, the arc-shaped center plate member 610 allows the fine material of the food material to be dropped back along the arc-shaped curved surface of the center plate 610 to below the storage container 510, 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 lid 520. The coupling cylinder 620 is threadedly coupled to the sealing lid 520 and a space is formed therein. The linear path (air flow hole) formed around the center plate 610 in this space and the bypass path (The first air passage and the second air passage) are in contact with each other to form a vortex.

FIGS. 7 and 8 are operational state diagrams showing two backflow prevention actions of the backflow prevention cap according to the present invention constructed as described above.

7, the backflow preventing cap 600 is formed in a shape of an upward convex shape of the edge plate 650 and the center plate 610, so that the fine material of the food material, which springs up during processing, Let it fall down. Food ingredients are placed in a storage container, vacuumed, and then the blade is rotated to grind the ingredients. At this time, since the blade provided in the storage container 510 rotates at a high speed, the powdered liquid food material rises on the wall surface of the storage container 510 due to the centrifugal force.

If the backflow preventing cap 600 is not provided, some of the food material fine particles will flow out of the storage container 510 through the check valve 530 attached to the sealing lid 520 due to the upward force . The microfluidized food material remains in the first vacuum chamber 450 and then flows into the vacuum motor along the vacuum tube 320 when the vacuum operation is performed.

The cap 600 for preventing backflow according to the present invention is installed in the lower part of the sealing lid 520 inside the storage container 510 to allow the rising food material to be dropped again below the storage container 510. As described above, since the centrifugal force is generated by the high-speed rotation of the blade, the fine particles of the food material rise toward the outside of the backflow preventing cap 600 because the bottom surface of the storage container 510 rotates upward. Accordingly, the backflow preventing cap 600 makes the edge plate member 650 the most wide convex upward, so that the rising fine food material can be lowered along the curved surface of the edge plate 650.

In addition, some of the ascending food material fine particles may bump into each other and may even protrude through the central space of the storage container 510. The backflow prevention cap 600 is formed into a convex upward shape with the center plate member 610 upward so that the fine material of the food material protruding toward the center of the storage container 510 is lowered again along the curved surface of the center plate member 610 I can do it.

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

8 shows another backflow prevention action of the backflow prevention cap 600 according to the present invention. When the vacuum operation is performed, the air in the storage container 510 rises and flows out to the outside through the check valve 530 of the sealing lid 520. At this time, (A).

First, some air containing the fine material of the food material is vertically raised through a linear path formed through the air flow holes 611 formed in the center plate member 610. Some of the air containing food ingredient fine water flows through the first air passage 660 horizontally formed between the center plate 610 and the edge plate 650 and a second air passage 660 formed between the center plate 610 and the coupling cylinder 620, Through the bypass passage formed by the second air passage 630 formed in the second air passage 630.

Thus, the air that has risen through the two air movement paths A is brought into contact with the inner space of the coupling cylinder 620. At this time, the air that has risen through the two paths collides with each other due to a difference in moving angle between them, and as a result, the vortical flow is weakened and the lifting force of the air is weakened for a certain period of time. The food material fine water contained in the air in the meantime is lowered again to the bottom of the storage container due to its weight gravity action (see route B in Fig. 8).

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

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