Description

Shortened operating time vacuum blender { VACUUM BLENDER FOR REDUCTING OPERATING TIME }

The present invention relates to a vacuum blender with reduced operation time, and in particular, during operation of the vacuum blender, it is possible to shorten the operating time by performing vacuum work and grinding work together while preventing fines or moisture from flowing back into the vacuum pump. It relates to a time-reducing vacuum blender.

A blender (mixer) is one of the most used electrical appliances at home today. Foods such as fruits, vegetables, grains, etc. are put inside the mixer container, and food is blended using a rotary blade rotatably installed at the bottom of the container. It is finely ground so that it can be consumed.

A typical blender puts food to be pulverized into a storage container, closes the lid, and rotates a rotary blade by a motor that rotates at high speed. .

For example, when fruits such as bananas and tomatoes are put in a blender and crushed, a large amount of bubbles are generated at the top of the fruit juice.

This not only reduces the taste and texture when drinking fruit juice, but also means that the fruit fiber has already been oxidized during the crushing process, and thus a significant portion of nutrients are destroyed.

In addition, when food is to be stored without being consumed immediately after grinding, when stored in a state exposed to the air, the oxidation process proceeds more rapidly, which accelerates the destruction of fiber and nutrients, and the color is discolored, reducing freshness, and air A layer separation occurs between the food and the food.

As such, there was a problem that it was difficult to store the food pulverized by the blender for a long period of time unless eaten immediately.

In order to solve this problem, vacuum blenders having various structures have been developed and released recently.

In a vacuum blender, when liquid food is put into a grinding container and pulverized, food fines are introduced into the vacuum pump by a vacuum suction force, and the vacuum pump and pressure sensor often fail.

In order to prevent this, most products calculate the pressure inside the grinding container in advance without a pressure sensor and control it with time, so that the vacuum time is uniformly set regardless of the amount of content.

In addition, the conventional vacuum blender cannot fully fill the inside of the grinding vessel with food (liquid, etc.) due to the above problems, and only about 40% of the size of the grinding vessel is put and ground, so the efficiency of the vacuum blender is reduced. .

In order to improve the inflow problem of fines, Patent Publication 10-2019-0019690 etc. shows a structure in which a backflow prevention means is mounted on the lower part of the container cover to prevent food fines from flowing backward and entering the vacuum pump.

However, in the case of such a conventional vacuum blender, a through hole is formed on the lower surface of the backflow prevention means, and liquid food or fines are immediately sucked upward through the through hole formed in the backflow prevention means by vacuum suction force during operation. A new problem has arisen that is introduced into the vacuum pump or pressure sensor.

In addition, when the vacuum work inside the grinding container and the grinding work are performed together, moisture or fine grains are introduced into the vacuum pump and the pressure sensor by the vacuum pressure of the pulverized fine materials, resulting in failure of the vacuum pump and pressure sensor. In order to prevent this, in the prior art, a vacuum operation inside the grinding container is first performed by a vacuum pump, and then a grinding operation by a blade is performed after the vacuum operation.

Therefore, in the prior art, since the vacuum operation time and the grinding operation time are separately configured, the operation time of the vacuum blender becomes long, and thus, there are many complaints from consumers that the operation time of the vacuum blender is long.

Patent Publication 10-2019-0019690

In general, the lower end of the container cover 30 is disposed at a higher position than the food stored in the grinding container 20 .

At this time, the high position refers to the height considering the expansion of the food (material) by vacuum pressure and the column of water caused by the centrifugal force generated while the blade rotates.

A discharge hole 31 is formed through the container cover 30 .

When the container cover 30 is coupled to the upper part of the grinding container 20, the mixing space 22 communicates with the outside through the discharge hole 31.

At this time, the discharge hole 31 is positioned above the lower end of the container cover 30 .

More preferably, the discharge hole 31 is positioned higher than the upper end of the grinding container 20 so that the food contained in the grinding container 20 does not come into contact with the discharge hole 31.

As described above, in the present invention, since the discharge hole 31 is located above the upper end of the grinding vessel 20, in a state in which the vessel cover 30 is coupled to the upper portion of the grinding vessel 20, vacuum pressure during vacuum The upper part of the water column generated by the expansion of the material (food) and the rotation of the blade 21 due to the contact with the discharge hole 31 can minimize reverse flow.

The communicating part 40 communicates the vacuum pump 12 and the mixing space 22 through the discharge hole 31 of the container cover 30 .

The check valve 50 is mounted on the discharge hole 31 or the communication part 40 and blocks external air from flowing into the mixing space 22 through the discharge hole 31 in a free state, open by external force.

In the drawing of this embodiment, the check valve 50 is equipped with the discharge hole 31, but it may be installed in an appropriate position in the communication part 40.

The check valve 50 opens the discharge hole 31 by an external force to communicate the mixing space 22 with the communication part 40 or the outside.

Since the specific shape and structure of the check valve 50 is sufficient to use a conventionally known one, a detailed description thereof will be omitted.

The lower part of the check valve 50 mounted in the discharge hole 31 is positioned above the lower part of the container cover 30 and the upper part of the grinding container 20 .

The foreign object receiving member 60 is detachably coupled to the lower portion of the container cover 30 at a portion where the discharge hole 31 is formed.

An accommodating space 64 is formed inside the foreign object receiving member 60 , and the accommodating space 64 accommodates fines generated when the food contained in the mixing space 22 is ground.

The foreign object receiving member 60 includes a receiving lower surface portion 61, a receiving side surface portion 62, and a suction passage 63.

The receiving lower surface portion 61 is disposed at a lower portion of the discharge hole 31 and spaced apart from the discharge hole 31, and is disposed between the lower surface of the container cover 30 and the upper portion of the receiving lower portion 61. The receiving space 64 is formed.

The receiving lower surface portion 61 may be formed in a flat shape or may be formed in various shapes so that fine objects may be well accumulated.

The receiving side surface portion 62 is formed to protrude upward along the circumference of the receiving lower surface portion 61 .

Therefore, the receiving space 64 is formed inside the receiving lower surface portion 61 and the receiving side surface portion 62.

The lower end of the foreign object receiving member 60 is located above the lower end of the container cover 30 and the upper end of the grinding container 20 .
In a state where the container cover 30 is coupled to the upper part of the grinding container 20, the lower end of the foreign object receiving member 60 prevents the upper part of the column of food water generated during food grinding from touching the discharge hole 31. is located above the upper end of the grinding container 20.

More specifically, the receiving lower surface portion 61 of the foreign object receiving member 60 is positioned above the lower end of the container cover 30 .

In general, when food is put into the grinding container 20, it is placed lower than the lower end of the container cover 30 covering the upper part of the grinding container 20.

In the present invention, the lower end of the foreign object receiving member 60 is located above the lower end of the grinding container 20, so that the food accommodated in the grinding container 20 is at the lower end of the foreign object receiving member 60. Contact can be prevented as much as possible, and this can suppress the inflow of fine materials into the foreign object receiving member 60 during grinding.

The suction passage 63 is formed between the lower surface of the container cover 30 and the upper surface of the receiving side surface portion 62 .

The suction passage 63 is positioned above the bottom of the container cover 30 and the top of the grinding container 20 .

The suction passage 63 may be formed by slightly spaced apart the lower surface of the container cover 30 and the upper surface of the receiving side surface portion 62, or between the lower surface of the container cover 30 and the receiving side surface portion 62. It may be formed by embossing or grooves formed therebetween by passages formed therebetween.

The foreign object receiving member 60 is detachably coupled to the lower surface of the container cover 30, so that foreign substances (fine objects) accommodated in the foreign object receiving member 60 can be easily removed and washed.

As the structure in which the foreign object receiving member 60 is detachably coupled to the lower surface of the container cover 30, it is sufficient to use various conventionally known structures.

In this embodiment, a hollow fastening protrusion 32 protrudes downward along the circumference of the discharge hole 31 on the lower surface of the container cover 30 .

Also, the foreign object receiving member 60 is detachably coupled to the hollow fastening protrusion 32 .

The foreign object receiving member 60 can be detachably coupled to the hollow fastening protrusion 32 in various ways. In the drawings of this embodiment, the foreign object receiving member 60 has the hollow fastening side portion 62 It was screwed to the protrusion 32.

At this time, a passage, a gap or a groove is formed in the middle between the receiving side portion 62 and the screw connection portion of the hollow fastening protrusion 32, so that the air moves smoothly.

In addition, the suction passage 63 is positioned lower than the lower end of the hollow fastening protrusion 32, so that fines flowing into the accommodation space 64 through the suction passage 63 are directly discharged through the discharge hole ( 31) is desirable.

In addition, the container cover 30 and/or the foreign object receiving member 60 are made of a transparent material.

Due to this, the user can easily see and clean the fines accommodated in the accommodating space 64 of the foreign object receiving member 60 from the outside.

Meanwhile, in the present invention, the motor 11 and the vacuum pump 12 are operated together.

In addition, when vacuuming in manual mode, it can operate in the same way as before.

Therefore, the vacuum of the mixing space 22 by the vacuum pump 12 and the grinding of the food by the motor 11 are performed together, so that the operation time of the vacuum blender can be shortened.

That is, in the past, grinding work was performed after vacuum work was performed to prevent backflow of food, so that the working time was long. You can control the pressure precisely by protecting it.

At this time, the reason why vacuuming and crushing cannot be performed at the same time in the prior art is that when food is vacuumed, the food expands in volume due to the vacuum pressure and increases in height, and the rotating column of the food crushed by the rotation of the blade rises. As a result, the top of the food is raised. When the food is crushed in this state, the fine substances generated during the grinding of the food are easily introduced through the discharge hole 31 and flowed back to the vacuum pump 12 to cause the vacuum pump ( 12) and the pressure sensor were damaged and could not function again.

However, since the discharge hole 31 and the suction passage 63 are disposed at a higher position than the upper end of the grinding container 20, even if the vacuum operation and the grinding operation are performed simultaneously, the vacuum pressure of the food is reduced. Even if the height of food increases due to expansion and rotation of the blade 21, contact with the discharge hole 31 and the suction passage 63 can be primarily prevented.

In addition, even if the fine substances generated when food is crushed are moved in the direction of the vacuum pump 12 and the pressure sensor by the vacuum suction force, since they are accommodated in the foreign object receiving member 60 and the container 42, the fine substances Inflow into the vacuum pump 12 and the pressure sensor can be blocked secondarily and thirdly.

As described above, the present invention can perform the grinding work by the motor 11 and the vacuum work by the vacuum pump 12 and accurate pressure control while blocking the fines, effectively reducing the operating time of the vacuum blender, A larger amount can be put into the grinding container at one time and the material can be ground.

Hereinafter, the operation process of the present invention consisting of the above-described configuration will be looked at.

Food is put into the mixing space 22 and the container cover 30 is closed.

At this time, the food exists below the lower end of the discharge hole 31 formed or mounted in the container cover 30, the check valve 50, and the foreign object receiving member 60.

Then, the communication part 40 is brought into close contact with the discharge hole 31 .

In this state, the motor 11 and the vacuum pump 12 are simultaneously operated.

Then, while the blade 21 disposed in the mixing space 22 is rotated by the motor 11, the food is mixed and ground.

At this time, when the food is pulverized, fine substances such as liquid are generated.

At the same time, by the suction force of the vacuum pump 12, the check valve 50 opens the discharge hole 31 by an external force, that is, a vacuum suction force, and thereby the air existing in the mixing space 22 is sucked. After passing through the passage 63, the discharge hole 31 and the communication part 40, it is discharged to the outside through the pressure sensor and the vacuum pump 12.

At this time, the fines generated when the food is ground can move together with the air, and the fines and moisture that move along with the air move through the suction passage 63 and accumulate in the receiving space 64 .

Conventionally, since a suction passage (through hole) was formed directly through the lower portion of the foreign object receiving member 60, when a large amount of food was put into the mixing space 22 and pulverized, the pulverized food was disposed on the lower surface of the foreign object receiving member 60. When in contact with the suction passage, the fines are sucked up straight up through the suction passage and move to the vacuum pump through the discharge hole, so the vacuum pump often breaks down. It is structured so that water enters directly through it.

Therefore, in the prior art, a small amount of food had to be put into the grinding container 20 and used, which was not efficient and the grinding operation had to be performed several times.

In addition, the pressure sensor is vulnerable to moisture, so most companies control the grinding vessel with a pressure sensor, calculating the inner area of the grinding vessel and controlling the vacuum level with time.

However, in the present invention, since the suction passage 63 is formed in the lateral direction rather than the lower part of the foreign object receiving member 60, when a lot of food is put in the mixing space 22 and pulverized, the pulverized food is Even if it comes in contact with the lower surface of the drip tray member 60, the fine water is not immediately sucked up into the suction passage 63 formed in the lateral direction, and even if it flows into the suction passage 63, it accumulates in the accommodation space 64. , It moves directly to the pressure sensor and the vacuum pump 12 through the discharge hole 31, thereby minimizing the failure of the pressure sensor and the vacuum pump 12.

In addition, since the flow path of the air and fines introduced through the suction passage 63 passes through the hollow fastening protrusion 32, the flow path is complicatedly changed, preventing the fines from easily moving to the discharge hole 31. can

In addition, in the present invention, the discharge hole 31 is located above the lower end of the container cover 30 and the upper end of the grinding vessel 30, and the fines moving through the discharge hole 31 are again recalled. Since it is accommodated in the storage container 42, it is possible to block fine objects from entering the pressure sensor and the vacuum pump 12 as much as possible.

As described above, the present invention can prevent the pressure sensor and the vacuum pump 12 from malfunctioning by easily moving to the pressure sensor and the vacuum pump 12 through reverse flow of fine matters generated when food is crushed, and the foreign object receiving member There is an effect that the user can easily detect the fine water accumulated in (60) and quickly clean it.

In particular, in the present invention, the discharge hole 31, the check valve 50, and the lower end of the foreign object receiving member 60 are located above the lower end of the container cover 30, and the foreign object receiving member 60 and the foreign object receiving member 60 are located above the lower end of the container cover 30. Since fine materials can be blocked from entering the pressure sensor and the vacuum pump 12 by the container 42, no problem occurs even when vacuuming and grinding work are performed at the same time, thereby drastically reducing the operating time of the vacuum blender. can be shortened to

The foreign object receiving member 60 may be formed in various shapes such as a cylindrical columnar shape and a polygonal columnar shape.

In addition, as shown in FIG. 4, the outer circumferential surface of the receiving side surface portion 62 may be formed by flattening or concavely chamfering a portion or several portions.

At this time, the suction passage 63 is formed through the lateral direction in the chamfered receiving side surface portion 62.

The suction passage 63 may be formed on the middle surface of the receiving side part 62, but preferably, as shown in FIG. 4, it is formed concave downward from the upper end of the receiving side part 62 and It is formed by penetrating the side portion 62.

At this time, it is sufficient for the suction passage 63 to have a small size through which air can move.

When the food is crushed by the blade 21 in a state in which a lot of food is put in, the rotating food moves along the outer circumferential surface of the receiving side portion 62 while drawing a circular motion trajectory.

In this embodiment, when the outer circumferential surface of the receiving side surface portion 62 is chamfered and formed, and the suction passage 63 is formed through the chamfered receiving side surface portion 62, the suction passage 63 forms the receiving passage 62 through the receiving side surface portion 62. ), it is possible to prevent food moving along a circular trajectory from easily entering the suction passage 63 formed in the chamfered portion.
