Description

Vacuum module for vacuum rice bucket

Technical Field

The invention relates to a vacuum module applied to a vacuum rice bucket. In particular, the present invention can prevent inflow of external air and maintain an internal vacuum state.

Background

The rice refers to grains peeled from seeds of rice. And the rice itself has a long circulation time. However, rice, which is a type of grain, needs to be kept in a cool and well ventilated place in order to prevent damage to rice.

Generally, rice is kept in a rice bucket. The rice barrel can prevent the rice from being vermin. As the rice bucket, a pottery (a storage container such as a pottery pot) or a plastic bucket made by baking loess or soil that can block moisture may be used.

The earthenware pot has a problem that it is expensive, heavy and easily broken when it is impacted. The plastic bucket causes the quality of rice to be reduced when the rice is stored for a long time. That is, the earthenware pot and the plastic tub have a problem that the rice is easily deteriorated or vermin is generated.

Therefore, in recent years, vacuum rice buckets for storing rice in a vacuum state have been used for storing rice.

As the name suggests, the vacuum rice bucket is a rice bucket that can keep rice in a vacuum state. By storing the rice in a vacuum state, excessive evaporation of water in the rice can be suppressed. Thereby, the rice can maintain a proper moisture state. In addition, discoloration of rice can be prevented. Furthermore, the rice stored in a vacuum state is free from the growth of insects. In addition, there is no need to worry about rice going moldy. That is, the vacuum can maintain freshness of rice and can keep rice for a long time.

This advantage results from the vacuum. Therefore, it is important to maintain a vacuum inside the vacuum rice bucket.

However, in the conventional vacuum rice bucket, when a motor or a pump for forming a vacuum inside is stopped, external air flows into the inside, thereby causing a problem that the degree of vacuum inside the vacuum rice bucket is lowered.

However, the present invention is not limited to the specific embodiments, and it should be understood that the present invention includes all modifications, equivalents, and alternatives included in the spirit and technical scope of the present invention.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise. In the present invention, terms such as "including" or "having" are used merely to indicate that features, numerals, steps, actions, constituent elements, components, or the combination described in the specification exist, and should not be understood as excluding the possibility that one or more other features, numerals, steps, actions, constituent elements, components, or the combination described exist or are appended in advance.

Next, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. At this time, it is to be noted that the same constituent elements in the drawings are denoted by the same reference numerals as much as possible. In addition, detailed descriptions about well-known functions and configurations which may cause the gist of the present invention to become unclear will be omitted. For the same reason, some of the constituent elements may be exaggerated, omitted, or schematically illustrated in the drawings.

A vacuum module for a vacuum rice bucket to which an embodiment of the present invention is applied is built in the cover 20. The lid 20 is disposed to seal the open part of the storage tub 10 for storing rice. The suction part 100 of the cover 20 may be formed to communicate with the storage bucket 10. Thereby, when the cover 20 is aligned in the storage tub 10, a portion other than the suction part 100 can be sealed.

The vacuum module for the vacuum rice bucket to which an embodiment of the present invention is applied includes a pumping part 100, a vacuum device 200, and a reverse flow preventing device 300. The piping 400 may be disposed between the suction unit 100 and the backflow prevention device 300 or between the backflow prevention device 300 and the vacuum device 200.

The suction part 100 is formed through the cover 20.

That is, as shown in fig. 1, the suction part 100 is formed to penetrate the cover 20 in the vertical direction. Accordingly, when the covers 20 are aligned, the covers 20 seal the storage bucket 10, and thus there is no space for air to enter and exit the storage bucket 10 except for the suction portion 100.

The suction part 100 may be a protrusion part formed with a suction hole at the center. That is, as shown in fig. 1, the suction portion 100 may be a convex portion that protrudes in a cylindrical shape to the upper side. With this, when the duct 400 is disposed in the suction portion 100, only the portion of the suction portion 100 communicating with the duct 400 constitutes an air moving passage.

The vacuum device 200 is disposed at a position spaced apart from the suction unit 100. The vacuum apparatus 200 may apply a suction force that sucks air in a side direction. The vacuum apparatus 200 is connected to the suction portion 100. Thereby, the vacuum apparatus 200 can move the air inside the keeping tub 10 in a one-side direction by applying a suction force to the suction part 100, thereby forming a vacuum in the keeping tub 10. The vacuum apparatus 200 is operated by a power source supplied from a power supply device not shown.

A backflow preventing device 300 may be disposed between the suction unit 100 and the vacuum apparatus 200. That is, the air moved in one direction by the suction part 100 may be moved to the vacuum apparatus 200 via the backflow preventing device 300. The reverse flow prevention device 300 allows air to move only in one direction. Accordingly, even when the air moving in one direction by the suction unit 100 is diffused and moved in another direction, the reverse flow preventing device 300 prevents the air from moving into the storage tub 10. The shape of the backflow preventing device 300 will be described in detail later.

The pipe 400 may be disposed between the suction part 100 and the backflow preventing device 300 or between the backflow preventing device 300 and the vacuum device 200. The circuit 400 may include a first circuit 410 and a second circuit 420. The first and second names are given for convenience of description, and the pipe 400 itself may not have any difference. The first pipe 410 and the second pipe 420 may be flexibly formed. Thereby, the first pipe 410 and the second pipe 420 may have elastic force.

The first and

second pipes

410 and 420 are formed with a set diameter. Wherein the diameters of the first and

second pipes

410 and 420 are smaller than the diameter of the pumping part 100. In addition, the diameters of the first and

second pipes

410 and 420 are smaller than the diameters of the inlet portion 340 and the outlet portion 350 of the backflow prevention device 300, which will be described later. In addition, the diameters of the first and

second pipes

410 and 420 are smaller than the diameter of the vacuum part 210 of the vacuum apparatus 200, which will be described in detail later. Thereby, one side of the first pipe 410 is forcibly insert-coupled to the suction part 100, and the other side is forcibly insert-coupled to the inlet part 340 of the reverse flow prevention device 300. One side of the second pipe 420 is forcibly fitted into the outlet part 350 of the reverse flow preventing device 300 and the other side is forcibly fitted into the vacuum part 210 of the vacuum device 200. Thereby, the sealing force between the respective components can be improved.

As shown in fig. 2, the vacuum module for a vacuum rice bucket of the present invention comprises: a suction section 100; a first pipe 410 connected to the suction part 100 at one side; a reverse flow preventing means 300 connected to the other side of the first pipe 410; a second pipe 420 connected to one side of the reverse flow preventing device 300; and a vacuum device 200 connected to the other side of the second pipe 420.

In this case, a part of the vacuum apparatus 200 may be formed in a cylindrical shape, and the vacuum apparatus 200 of the shape should be fixedly disposed when it is built into the cover 20. This is because the vacuum apparatus 200 applies a suction force by means of a supplied power source and thus causes a shaking phenomenon, and if the cylindrical portion of the vacuum apparatus 200 is not properly fixed, a positional change may be caused and thus a gap (gap) may be formed at the connection portion.

In order to prevent the phenomenon as described above, the present invention includes the support frame 30. The support frame 30 is formed in a "L" shape as shown in FIG. 2. That is, a step may be formed in the support frame 30. Further, two support frames 30 may be disposed at a certain interval. Thereby, the cylindrical portion of the vacuum apparatus 200 can be supported and fixed by the portion of the support frame 30 where the step is formed. Further, the cylindrical portion of the vacuum apparatus 200 may be supported at symmetrical positions by means of the support frame 30. The support frame 30 of the present invention supports and fixes the vacuum apparatus 200 in such a manner as described above, thereby supporting the vacuum apparatus 200 without movement and thereby ensuring the safety of the apparatus.

The backflow prevention device 300 may include a housing 310, a sealing portion 320, a closing portion 330, an inlet portion 340, and an outlet portion 350.

The housing 310 may have a cylindrical shape and may have a hollow space formed therein. The housing 310 may function as a skeleton of the backflow prevention device 300.

The sealing part 320 may be disposed inside the case 310 in a state of closing a hollow space inside the case 310. The sealing part 320 may include a communication hole. The communication hole is formed to penetrate the sealing part 320, and there is no space for air to move on one side and the other side of the sealing part 320 except for the communication hole with respect to the sealing part 320. That is, with reference to fig. 3, there is no space for communicating the left and right sides of the sealing part 320 except for the communication hole.

The closing part 330 may close the communication hole and continuously apply a force in one side direction. As an example of the closing part 330, a cover to which a spring is attached may be cited. Therefore, the closing part 330 may be in a form of continuously applying a force to the right side with reference to fig. 3. By means of the closing part 330, the air may be allowed to move only in one side direction.

Referring to fig. 3, in the case where air moves from the right side to the left side, the air may push the closing part 330 to the left side and move through the space formed thereby. However, when the air moves from the left side to the right side, the force applied to the right side by the closing portion 330 continuously increases. Therefore, the communication hole will maintain a closed state, thereby preventing air from moving from the left side to the right side.

The inlet part 340 is formed to be elongated at one side of the housing 310, and the outlet part 350 is formed to be elongated at the other side of the housing 310. Wherein, as shown in fig. 3, the one side may be a right side in fig. 3 and the other side may be a left side.

The inlet part 340 is a part where air moved from the suction part 100 can move. The outlet port 350 is a portion through which air moving through the communication hole can be discharged and moved to the vacuum apparatus 200.

The inlet part 340 and the outlet part 350 are formed in a symmetrical shape. The diameter of the inlet portion 340 becomes continuously smaller toward the right side. The diameter of the outlet portion 350 becomes continuously smaller toward the left side.

Therefore, as shown in fig. 1 and 2, the inlet 340 and the outlet 350 can be more easily and firmly connected to each other when the first pipe 410 and the second pipe 420 are connected to each other.

In the backflow prevention device 300 to which the second embodiment is applied, the sealing part 320 and the closing part 330 may be integrally formed. The backflow prevention device 300 to which the second embodiment is applied includes similar configurations (e.g., the housing 310, the inlet 340, and the outlet 350, etc.) to the backflow prevention device 300 to which the first embodiment is applied. Therefore, the following description will mainly deal with differences between the backflow prevention device 300 to which the second embodiment is applied and the backflow prevention device 300 to which the first embodiment is applied.

In the backflow prevention device 300 to which the second embodiment is applied, the mounting portion 311 may be formed. Referring to fig. 4, the mounting portion 311 may be formed to close a portion of the hollow space of the housing 310 at the lower side of the housing 310. The mounting portion 311 may narrow a hollow space of the housing 310, and a cross-section thereof may be formed in a shape similar to a "l". That is, since the mounting portion 311 exists, a stepped portion may be formed at the lower side of the housing 310.

The sealing part 320 may be made of a material having an elastic force. The sealing portion 320 may be disposed to surround the mounting portion 311. One side (lower side in fig. 4) of the sealing part 320 may be slightly smaller than the diameter of the mounting part 311. Therefore, the sealing portion 320 may be disposed along the outer periphery of the mounting portion 311 in a manner that the inner surface of the sealing portion 320 pressurizes the mounting portion 311. Thereby, the lower side of the sealing part 320 and the mounting part 311 can be strongly coupled and sealed therebetween.

A communication hole may be formed at the other side (upper side in fig. 4) of the sealing part 320. Among them, since the sealing part 320 is made of a material having an elastic force, it always has a property of restoring an original shape. This may be named the closing part 330. That is, the periphery of the communication hole of the sealing part 320 may be named as a closing part 330.

Before the shape of the closing portion 330 is deformed, the communication hole may be closed by the closing portion 330. However, in the case where air moves from the right side to the left side with reference to fig. 4, the constricted portion of the closing portion 330 can expand and expand (see the enlarged view of fig. 4), thereby opening the communication hole. Thereby, air can move to the left side through the communication hole.

Next, when the flow of air is stopped, the closing portion 330 is restored (contracted) to the original form and is deformed again to a form closing the communication hole. When air moves from the left side to the right side, the closing portion 330 is further assisted in contraction to maintain the state in which the communication holes are closed, and the communication holes cannot be opened.

Thereby, the air can move from the right side to the left side with reference to fig. 4, but cannot move in the reverse direction.

As described with reference to fig. 3 and 4, the present invention may allow air to move in one direction but not in the other direction by disposing the backflow prevention device 300.

Therefore, in the case where the vacuum apparatus 200 is operated, the air inside the storage bucket 10 is allowed to move in one direction of the air discharged to the outside, but after the operation of the vacuum apparatus 200 is completed, the air is not allowed to reversely flow into the storage bucket 10. Thereby, the vacuum keeping barrel 10 for forming the vacuum can maintain the vacuum state.

Fig. 5 is an enlarged view of a vacuum unit, the other side of the backflow prevention device, the second pipe, and the pressure ring of the vacuum apparatus to which the vacuum module according to the embodiment of the present invention is applied.

Further, the present invention may include a compression ring 500.

The pressing ring 500 may be a ring that presses the respective constituent connection portions. As an example, as shown in fig. 5, may be disposed along the circumference of the second pipe 420.

As an example, one side of the second pipe 420 may be connected with the outlet part 350 of the reverse flow prevention device 300, and the other side may be connected with the vacuum part 210 of the vacuum device 200. A pressurizing ring 500 for pressurizing the second pipe 420 along the circumference of the second pipe 420 may be disposed at one side of the second pipe 420.

The pressurization ring 500 may pressurize the second pipe 420, thereby increasing a sealing force by strongly pressurizing between the second pipe 420 and the outlet part 350 of the backflow prevention device 300.

Although not shown, the pressure ring 500 may be disposed at a portion where the suction part is connected to the first pipe 410, a portion where the inlet part 340 is connected to the first pipe 410, and a portion where the second pipe 420 is connected to the vacuum part 210.

Although an embodiment of the present invention has been described in detail in the foregoing, those having ordinary skill in the art can make various modifications and variations to the present invention by adding, changing, deleting or adding components without departing from the scope of the present invention as set forth in the claims, and the modifications and variations are also included in the scope of the claims of the present invention.
