FIG. 6 is a cross-sectional view showing a combined state of a case and a reinforcing member according to an embodiment of the present invention, FIG. 7 is a side sectional view of a case according to an embodiment of the present invention, and FIG. Fig. 10 is a front view of a case according to an embodiment of the present invention, Fig. 11 is a cross-sectional view taken along line AA of Fig. Fig. 12A is a cross-sectional view taken along a line I-I in Fig. 11, and Fig. 12B is a cross-sectional view of a guide passage according to another embodiment of the present invention.

3 to 6, a vegetable compartment 100 for a refrigerator according to an embodiment includes a case 110, a drawer 120, an outlet 180, an on-off valve 170, a guide passage 200a -200d).

The case 110 has a structure that forms an outer appearance of a vegetables room 100 for a refrigerator and is installed in a storage room F (R) in the main body 2 of the refrigerator. The case 110 has a double structure of an inner case and an outer case, the outer case is fixed to the storage room F, and the inner case can be installed in the outer case in a detachable manner.

The case 110 is formed with an opening 113 at the front, and a storage space A, which is a storage space for the stored product, may be formed therein.

For example, the case 110 may be formed as a rectangular parallelepiped having a storage space A therein. More specifically, the case 110 can be formed so that only the front (the opening 113) in which the drawer 120 is stored or drawn out is opened and the remaining five sides are blocked. That is, referring to FIG. 2, the case 110 has an opening 113 at the front, a rear surface 110d of the case is disposed at the rear, a top surface 110a of the case and a bottom surface 110c And side surfaces 110b of the case may be disposed on both sides. The upper surface 110a of the case and the lower surface 110c of the case may have a larger area than the side surface 110b of the case.

A decompression unit 190 may be installed on one side of the case 110 to form a negative pressure (and a vacuum) inside the case 110. The decompression unit 190 may be implemented by, for example, a pump (vacuum pump).

Also, although not shown in the drawing, the decompression unit 190 may be connected to the case 110 by a connection pipe. Accordingly, when the drawer 120 is housed in the case 110, the air inside the case 110 can be discharged to reduce the pressure inside the case 110

A flange 119 extending to the outside of the storage space A may further be formed at the rim of the opening 113. That is, the flange 119 may be formed so as to extend outwardly in front of the case 110.

The flange 119 may be disposed perpendicular to the side surface 110b and the upper and lower surfaces of the case. Here, the flange 119 is vertically disposed, meaning that the flange 119 is elongated in the vertical direction and the lateral direction of the case 110. In addition, the above-mentioned vertical meaning does not mean a perfect vertical in a mathematical sense but means a vertical range including an error in an engineering sense.

The flange 119 is disposed perpendicular to the upper surface 110a and the lower surface 110b of the case so as to prevent sagging of the edge of the opening 113 caused by the negative pressure inside the case 110. [ Specifically, the flange 119 is formed in the vertical direction of the case 110, and can function as a bending stress supporting body that resists the bending stress generated at the rim of the opening 113. [

The flange 119 also provides a region in contact with the drawer 120 when the drawer 120 seals the interior of the case 110. Particularly, when the inside of the case 110 is kept close to a vacuum, the inside of the case 110 must be completely sealed with the outside. Since the flange 119 provides a space in which the drawer 120 contacts, Thereby improving the sealing performance of the vegetable compartment 100. In addition, when the sealing member 140 is used in the contact area between the drawer 120 and the case 110, it also provides a space for the sealing member 140 to contact.

At least one side of the rim of the opening 113 may be formed in an arcuate structure in which the central portion protrudes outward of the storage space A.

For example, as shown in Fig. 5, the rim of the opening 113 has a rectangular shape composed of the upper surface 110a of the case, the lower surface 110c of the case, and the side surface 110b of the case. The upper surface 110a of the case 110 and the lower surface 110c of the case 110 are generally longer than the side surface 110b of the case 110, A large deformation occurs due to the bending stress caused by the external pressure difference. Therefore, when one side of the rim of the opening 113 (for example, the front end of the upper surface 110a of the case) has an arcuate structure in which the central portion protrudes outward of the storage space A, It is possible to effectively resist the bending stress acting on the support member. As a result, when the rim of the opening 113 is designed to have an arcuate structure, it is possible to prevent the periphery of the opening 113 of the case 110 from being bent into the case 110.

The case 110 may further include a reinforcing rib 111 reinforcing the strength of the case 110.

The reinforcing ribs 111 are members formed in a direction in which the case 110 is deformed and can be formed integrally with the case 110 by injection molding.

For example, the reinforcing ribs 111 may be formed on the outer surface of the case 110 in order to secure the storage space A inside the case 110. In addition, a plurality of reinforcing ribs 111 may be formed in the first direction and a plurality of reinforcing ribs 111 may be formed in the direction intersecting the first direction.

On the inner surface of the case 110, a rail 117 may be formed to guide the drawer 120 so that the drawer 120 may be withdrawn in a drawer form. For example, the rail 117 is formed on the side surface of the inner surface of the case 110, and is formed long in the front-rear direction.

The lower surface 110c of the case 110 closes the inside of the case 110 and forms an appearance of the refrigerator warehouse 100 together with the case 110. [

For example, the drawer 120 may include a receiving portion 123 forming a storage space for storing the stored contents therein, and a front portion 121 disposed in front of the storage portion 123.

The storage part 123 is put in and out of the case 110 as a drawer. A guide 129 is formed on the outer surface of the housing part 123 so as to correspond to the rail 117 of the case 110 so that the housing part 123 is inserted into the case 110, It is moved forward and backward according to delivery.

For example, the receiving portion 123 may have a hexahedron shape in which an upper portion and a front portion are opened.

The front portion 121 may be disposed in front of the storage portion 123 and may have an expanded size as compared with the storage portion 123. [ Therefore, the rim of the front portion 121 comes into contact with the rim of the opening 113 to close the case 110. [

The front portion 121 may be formed in a substantially rectangular (rectangular parallelepiped) shape. More specifically, it is preferable that the flange 119 of the opening 113 has a size and shape corresponding to the size and shape of the flange 119. That is, the front portion 121 may be formed so as to be in contact with the flange 119 of the case 110.

Also, the front part 121 may be provided with a handle 125 for drawing or storing.

The handle 125 may be provided in an upper region of the front portion 121. [

The handle 125 may be formed so as to be recessed rearward so as to form a gripping space from the front surface of the front portion 121, for example.

When the inside of the case 110 is sealed by the drawer 120, a pressure difference is generated between the inside and the outside of the case 110. That is, when the inside of the case 110 is sealed by the drawer 120, the interior of the case 110 is depressurized by the depressurizing portion, so that the pressure becomes lower than the outside of the case 110. [

A sealing member 140 may be provided at the contact area between the front part 121 of the drawer 120 and the opening 113 so as to seal the inside and the outside of the case 110 when the drawer 120 is received. have.

The discharge port 180 is formed to penetrate the lower surface 110c of the case 110 to discharge the water generated in the case 110 to the outside of the case 110. [

The outlet 180 is preferably positioned lower than the bottom surface 110c of the case so that water generated inside the case 110 is collected by gravity. The water in the case 110 is dew which is generated when the temperature of the water in the case 110 drops below the dew point temperature.

More specifically, the lower surface 110c of the case may be formed to be inclined downward toward the discharge port 180 in order to efficiently guide the water flowing by gravity to the discharge port 180. [

The discharge ports 180 may be arranged in various numbers, but when the discharge ports 180 are arranged in one, it is advantageous to arrange the discharge ports 180 at the center of the lower surface 110c of the case.

In addition, the discharge port 180 may be provided with an opening / closing valve 170 for opening and closing the discharge port 180 to control the discharge of the collected water. The opening / closing valve 170 will be described in detail later.

8 and 9, the embodiment further includes an air inlet / outlet hole 127 through which air enters and exits from the drawer 120, and is provided in the drawer 120 to open / close the air inlet / And may further include a holding device 300.

The air inlet / outlet hole 127 is formed through the drawer 120 so that the air outside the case 110 can flow into and out of the case 110. When external air is introduced through the air inlet / outlet hole 127, the vacuum state inside the case 110 is released.

For example, the air inlet / outlet hole 127 is formed in the front portion 121 of the drawer 120.

The airtight holding device 300 is provided in the drawer 120 to open / close the air inlet / outlet hole 127 by an external force and an elastic force.

The closed holding device 300 may be exposed to the outside of the drawer 120 or embedded in the drawer 120.

8, the front portion 121 of the drawer 120 is provided with a receiving portion 128 for receiving the sealing device 300 and a shielding portion 400 for shielding the receiving portion 128 ).

The receiving portion 128 is formed by recessing a part of the front portion 121 of the drawer 120 in the direction of the receiving portion. The receiving portion 128 may be formed in a substantially hexahedral space and may be located at the center of the front portion 121 of the drawer 120.

The shielding portion 400 shields the accommodating portion 128 and is disposed so as to expose an operation switch 340, which will be described later. That is, the shielding part 400 shields the closing and holding device 300 from the outside and exposes only the operation switch 340, in order to improve the feel of the appearance of the drawer 120.

For example, the closed holding device 300 may include a sealing portion 310, a driving arm 320, a compression spring 330, and an operation switch 340.

The sealing portion 310 seals the air inlet / outlet hole 127. It is preferable that the sealing portion 310 is formed in a shape having a large contact area with the air inlet / outlet hole 127 so as to close the air inlet /

Specifically, the sealing portion 310 may have a hemispherical shape protruding toward the air inlet / outlet hole 127, and a rim of the air inlet / outlet hole 127 may have a shape corresponding to the sealing portion 310.

The sealing portion 310 is preferably made of a material whose shape is deformed so as to effectively seal the air inlet / outlet hole 127 when it comes into contact with the air inlet / For example, the material of the closure 310 may include rubber or silicone material.

The driving arm 320 is rotatably installed on the drawer 120 and transmits the driving force of the external force to the sealing unit 310.

The drive arm 320 is hinged to the hinge part 500 protruding upwardly (as viewed in FIG. 2) from the front part 121 of the drawer 120. In order to provide a space for the drive arm 320 to rotate, And can be rotatably provided.

For example, the driving arm 320 is provided at its center with a pivot shaft 323 rotatably inserted into the hinge unit 500, and one end 321 of the driving arm 320 is coupled with the sealing unit 310 And the other end 322 of the drive arm 320 disposed symmetrically about the one end 321 of the drive arm 320 and the rotation axis 323 is supported by the compression spring 330.

The compression spring 330 provides an elastic force to the drive arm 320 so that the seal 310 closes the air inlet and hole 127.

A fixing protrusion 122 protruding upward from the front portion 121 of the drawer 120 may be formed so as to fix the position of the compression spring 330. One end of the compression spring 330 is fixed to the fixing protrusion 122, respectively. The other end 322 of the driving arm 320 may be formed with a groove for fixing the other end of the compression spring 330.

The operation switch 340 is provided in the drawer 120 and operates the drive arm 320 to rotate between the closed position and the released position. That is, when the user applies an external force to the operation switch 340, the operation switch 340 transmits an external force to the drive arm 320.

Specifically, the operation switch 340 is disposed above the other end 322 of the drive arm 320, and the compression spring 330 can be disposed below the other end 322 of the drive arm 320. Therefore, when an external force is applied to the operating switch 340, the elastic force is overcome and the other end 322 of the driving arm 320 moves downward to separate the sealing portion 310 from the air inlet / , When the external force is released to the operation switch 340, the operation switch 340 is returned to the initial position by the elastic force of the compression spring 330. That is, the operation switch 340 and the compression spring 330 may be disposed symmetrically up and down with respect to the driving arm 320.

The operation switch 340 is disposed to be exposed to the outside of the front portion 121 of the drawer 120 and can be arranged to be reciprocally movable in the vertical direction.

Specifically, when the receiving portion 128 is shielded by the shielding portion 400, one region 510 can be opened. The operation switch 340 is installed to be able to reciprocate up and down in one area 510 described above.

More specifically, the operation switch 340 includes an operation plate 341 exposed to the outside and disposed on the same plane as the shield 400, And a guide piece 343 extending downward from the rim of the operation plate 341 and guided by the operation switch guide 410 to be described later .

Preferably, the shielding portion 400 may further include an operation switch guide 410 for guiding movement of the operation switch 340.

Specifically, the operation switch guide 410 may be formed by extending a certain length downward from the rim of the area 510 of the shielding part 400.

Referring to FIGS. 8 and 9, an operation method of the embodiment will be described as follows.

8, when the drawer 120 closes the case 110, the inside of the case 110 becomes a vacuum state by the decompression unit 190. At this time, the operation switch 340 is positioned at the initial position by the elastic force of the compression spring 330. The other end 322 of the drive arm 320 is moved upward by the elastic force of the compression spring 330 and the one end 321 of the drive arm 320 disposed symmetrically about the rotation axis 323 So that the sealing portion 310 seals the air inlet / outlet hole 127. Accordingly, the vacuum state inside the case 110 is maintained.

9, when the drawer 120 is opened in the case 110, when the user applies an external force to the operation switch 340 and presses it, the force of the compression spring 330 is overcome, The other end 322 of the driving arm 320 is moved downward and the one end 321 of the driving arm 320 disposed symmetrically about the pivot 323 is moved upward so that the sealing portion 310 is moved to the air inlet / . Thus, the weakened state inside the case 110 is released, so that the user can open the drawer 120 easily.

The embodiment can easily release the vacuum state inside the case 110 by pressing the operating switch 340 before the drawer 120 is opened.

As a result, when the inside of the case 110 is in a vacuum state, the drawer 120 can not be opened easily even by an adult due to a pressure difference between the inside and the outside of the case 110. In the closed holding device 300 of the embodiment The vacuum state inside the case 110 can be released, so that the drawer 120 can be opened easily.

Referring to FIGS. 5 to 7 and FIGS. 10 to 12, the guide channels 200a to 200d are formed on the inner surface of the case 110 to guide water generated in the case 110 toward the discharge port 180. In addition, the guide passages 200a-200d serve to prevent the dew formed inside the case 110 from being seen by the naked eye.

The guide paths 200a-200d may be formed on at least one surface of the inner surface of the case 110, but preferably the guide paths 200a-200d may be formed on all inner surfaces of the case 110. [

The guide flow paths 200a-200d can be formed in various shapes.

The guide flow paths 200a-200d may be formed by recessing and protruding the inner surface of the case 110 and guiding water in the direction of the discharge port 180. [

For example, the guide paths 200a to 200d include at least two mountains 210 protruding inwardly of the case 110, and a plurality of protrusions (not shown) disposed between the mountains 210, 220 < / RTI >

The mountain 210 is protruded from the valley 220 so that the water generated inside the case 110 can flow to the valley 220, which is formed long in one direction. The trough 220 is formed between the mountain 210 and the mountain 210 to be lower than the mountain 210 to provide a path for guiding the water.

12, the cross-sectional shape of the mountain 210 may have any one of triangular, square, and semicircular shapes. That is, when the cross-sectional shape of the mountain 210 has a triangular shape or a semicircular shape, the dew formed on the inner surface of the case 110 is easily moved to the trough 220 and is not visible to the user's eyes.

More specifically, the mountain 210 may be formed by two inclined surfaces 211 and 212. That is, the mountain 210 may have a triangular or rectangular cross section with two slopes 211 and 212.

The pitch P between the mountain 210 and the mountain 210 is preferably 1.5 mm to 2.5 mm. If the pitch P between the mountain 210 and the mountain 210 is larger than 2.5 mm, the dew formed on the inner surface of the case 110 can not easily move to the valley 220, 210 are smaller than 1.5 mm, the valleys 220 do not provide sufficient space for collecting dew, and there is a problem that the dew is visually seen.

The height of the mountain 210 is preferably 1.5 mm to 2.5 mm. If the height of the mountain 210 is too high, the strength of the case 110 is lowered, and if the height of the mountain 210 is too low, there is a problem that the valley 220 does not provide sufficient space for gathering dew.

Hereinafter, the guide flow paths 200a-200d formed on each side of the case 110 will be described in detail.

Referring to FIGS. 5, 7, 10 and 11, the guide passages 200a to 200d include upper guide passages 200a, a side guide passage 200b, a rear guide passage 200d, 200c.

The upper surface guide passage 200a is formed on the inner surface of the upper surface 110a of the case. It is preferable that the mountain 210 and the valleys 220 of the upper surface guide passage 200a are formed in the direction of both side surfaces 110b of the case. The mountain 210 and the valleys 220 of the upper surface guide passage 200a may be formed in the direction from the front of the case 110 to the rear surface 110d of the case.

More preferably, the upper surface 110a of the case is formed so as to be capable of being guided by the gravity to the side surface 110b of the case along the upper surface guide passage 200a with water generated from the inner surface of the upper surface 110a of the case, (110b). That is, as shown in FIG. 10, the upper surface 110a of the case may have an arch shape in which the central portion protrudes to the upper portion of the case 110. [ When the upper surface 110a of the case is formed as described above, the strength of the upper surface 110a of the case increases and water formed on the upper surface 110a of the case can be guided toward the side surface 110b of the case by gravity have.

The side surface guide passage 200b is formed on the inner surface of both side surfaces 110b of the case. The mountain 210 and the valley 220 of the side guide passage 200b may be formed in the direction from the upper surface 110a of the case to the lower surface 110c of the case. This is to allow water generated at the side surface 110b of the case to flow by gravity in the direction of the bottom surface 110c of the case.

The upper surface guide passage 200a and the valleys 220 of the side guide passage 200b are connected (communicated) to each other so that the water formed on the upper surface 110a of the case is effectively guided to the side surface 110b of the case desirable.

The rear guide passage 200d is formed on the inner surface of the rear surface 110d of the case. The mountain 210 and the valley 220 of the rear guide passage 200d may be formed in the direction from the upper surface 110a of the case to the lower surface 110c of the case. This is to allow water generated at the rear surface 110d of the case to flow by gravity in the direction of the bottom surface 110c of the case.

The lower surface guide passage 200c is formed on the inner surface of the lower surface 110c of the case.

The mountain 210 and the valleys 220 of the lower surface guide passage 200c may be formed in the direction of the discharge port 180. [ This is to allow the water generated inside the case 110 to flow by the gravity in the direction of the discharge port 180. Further, in order to more effectively collect water, the lower surface guide passage 200c may be formed to be inclined downward in the direction of the discharge port 180. [

For example, the lower surface guide passage 200c may be formed in a radial shape with the discharge port 180 as a center. Of course, in order to effectively collect water, the trough 220 of the upper surface guide passage 200a, the trough 220 of the side guide passage 200b and the trough 220 of the lower surface guide passage 200c are connected .

Therefore, as shown in Fig. 10, the water (dew) generated in the case 110 can be collected into the discharge port 180 along the water movement path f.

The reinforcing portion functions to reinforce the strength of the case 110.

For example, the reinforcing portion may be embodied as at least a reinforcing member 130 coupled to one surface of the case 110. When the opening 113 is formed in front of the case 110, the pressure inside the case 110 is lower than the pressure outside the case 110, so that the rim of the opening 113 is directed toward the inside of the case 110 The sagging phenomenon occurs. When the reinforcing member 130 is disposed, such sagging phenomenon can be prevented. Here, the rim of the opening 113 means the front end 110a of the case, the bottom surface 110c of the case, and the forward end of both side surfaces 110b of the case 110.

More specifically, the reinforcing member 130 may be disposed on the surface of the case 110 that has the largest area. 5, when the case 110 is formed in a rectangular parallelepiped shape having the opening 113 at the front, the position where the deformation is most likely to occur due to the pressure difference between the inside and the outside of the case 110 is the case (The upper surface 110a and the lower surface 110c of the case) having the largest surface area among the surfaces of the upper surface 110a and the lower surface 110a. Therefore, it is effective to prevent the deformation of the opening 113 when the reinforcement member 130 is adjacent to the rim of the opening 113 and the area of the surface of the case 110 is the largest.

The reinforcing member 130 may be disposed on the upper surface 110a of the case. When the reinforcing member 130 is disposed inside the case 110, the reinforcing member 130 is preferably coupled to the outside of the upper surface 110a of the case, Do.

It is preferable that the reinforcing member 130 is positioned adjacent to the opening 113 because the largest deformation occurs at the rim of the opening 113. [

The reinforcing member 130 may be disposed parallel to the rim of the opening 113. Here, the meaning of parallelism does not mean parallelism of mathematical meaning but means parallelism including an error in engineering sense. In addition, the parallel lines include not only parallel lines between straight lines but also correspondingly arranged at a constant distance from each other in a curve. When the reinforcing member 130 is disposed in parallel with the rim of the opening 113, deformation of the rim of the opening 113 can be prevented more effectively.

Further, the reinforcing member 130 may be disposed on the upper surface 110a and / or the lower surface 110b of the case, and one side may be engaged with the flange 119. The deformation of the rim of the opening 113 can be more effectively prevented by the engagement of the flange 119 and the reinforcing member 130. [

The reinforcing member 130 may have various shapes that are resistant to bending stress. For example, the reinforcing member 130 includes a first member 131, a second member 133 disposed to be spaced apart from the first member 131, and a second member 133 disposed between the first member 131 and the second member 133. [ And a connection member 135 having a through hole 136 through which a bolt fastened to the case 110 is formed. That is, the reinforcing member 130 may have a C shape that is resistant to bending stress. The case 110 may be formed with a boss 114 to which a bolt is fastened at a position corresponding to the through hole 136.

Preferably, the first member 131 and the second member 133 may be disposed perpendicular to the upper surface of the case 110, in order to increase the resistance against the stress. That is, the first member 131 and the second member 133 can be arranged in the vertical direction of the case 110.

One end of the first member 131 and the second member 133 come in contact with one surface of the case 110 and are formed at the same height as the reinforcing ribs 111 so as to reduce the space occupied by the reinforcing member 130. [ . At this time, the connecting member 135 may be disposed at the same height as the upper end of the reinforcing member 130.

The reinforcing member 130 may be formed of a material having a strength greater than that of the case 110. For example, the reinforcing member 130 includes a metal material and an alloy material, and may specifically include at least one of steel, a steel alloy, an aluminum alloy, a titanium alloy, stainless steel, and a stainless steel alloy. However, the present invention is not limited thereto.

FIG. 13 is an enlarged cross-sectional view of the region B in FIG. 7, FIG. 14 is a cross-sectional view showing the opening and closing valve of FIG. 13 when opened, and FIG. 15 is a perspective view of an opening and closing valve according to an embodiment of the present invention.

13 to 15, the discharge port 180 may be partitioned into a collecting section 181 and a discharging section 182. The directions mentioned below are based on Figs. 11 and 12.

As shown in Fig. 13, the outlet 180 is a hole formed through the lower surface 110c of the case. The shape of the discharge port 180 is not limited, and various shapes are possible to provide a passage through which water is discharged. It is preferable that the valve shaft 172 of the on-off valve 170 has a shape corresponding to the valve axis 172 of the on-off valve 170 so that the valve shaft 172 of the on-

The water collecting part 181 may be formed by recessing a part of the lower surface 110c of the case so that water in the case 110 is collected. The water collecting part 181 is a place where the water generated in the case 110 flows along the inner surface of the case 110 and collects. Further, a space in which the elastic spring 174 to be described later is provided is provided inside the water collecting part 181, and serves as a support part of the elastic force of the elastic spring 174.

The discharge portion 182 allows the water collecting portion 181 to communicate with the outside of the case 110 so that the water collected in the water collecting portion 181 can be discharged to the outside of the case. The discharge portion 182 may have a width smaller than that of the collecting portion 181. Here, the width means the length in the left-right direction with reference to Fig. The discharge portion 182 may have a smaller size or an inner diameter than the collecting portion 181. [

One end of an elastic spring 174, which will be described later, is located at a step generated by the width difference between the collecting part 181 and the discharging part 182 (or the bottom of the collecting part 181).

More specifically, the collecting section 181 and the discharging section 182 both have a hole shape and can share a central axis, and the outer diameter of the collecting section 181 can be formed larger than the outer diameter of the discharging section 182 . That is, a part of the lower surface 110c of the case 110 is recessed to form the catching portion 181, and a discharge portion 182 through which the lower surface of the catching portion 181 penetrates and communicates with the outside of the case 110 can be formed have.

For example, the discharging portion 182 may be a through-hole formed at the bottom of the collecting portion 181. As another example, the discharge portion 182 may be a hole formed by a boss portion 184 protruding downward from the bottom surface 110c of the case.

The boss portion 184 may be integrally formed with the case 110, or may be separately manufactured and then combined. The boss portion 184 protrudes downward from the bottom surface 110c of the case to provide a place where the plug 171 of the on-off valve 170 described later is inserted and sealed.

For example, an empty space is formed in the boss portion 184 so that the discharge portion 182 is formed, and the opening / closing valve 170 is reciprocated to discharge water inside the case 110. A sealing surface 184a formed to correspond to the plug 171 may be formed on the surface of the boss 184 on which the plug 171 contacts.

More specifically, when the plug 171 is spherical, the sealing surface 184a may be formed by recessing one end of the boss portion 184 in a hemispherical shape.

Further, in order to enhance the sealing force, the material of the boss portion 184 may be formed of any one material of rubber, synthetic resin, and silicone. Of course, the boss portion 184 may include the same material as the material of the case 110.

The opening and closing valve 170 according to the embodiment reciprocates within the discharge port 180 to open and close the discharge port 180. Further, the opening / closing valve 170 may be moved to one side by an external force and opened and may be moved to the other side by elastic force and closed. For example, the on-off valve 170 may be moved to one side by contact with the drawer 120 and opened, and may be moved to the other side by an elastic force and closed.

The position of the opening / closing valve 170 is not limited. Preferably, the opening / closing valve 170 is disposed adjacent to the opening 113 of the case 110. When the opening and closing valve 170 is disposed adjacent to the opening 113 of the case 110, the drawer 120 is not completely detached from the case 110 and is not recognized by the user's eyes.

For example, the on-off valve 170 may include a plug 171, a head 173, a valve shaft 172, and an elastic spring 174.

The plug 171 reciprocates upward and downward to serve to open and close the discharge portion 182.

The plug 171 may have various shapes that open and close the discharge portion 182 and seal the discharge portion 182. For example, the plug 171 may have a larger width (or outer diameter) than the discharge portion 182, and the plug 171 may be formed in a spherical shape. Of course, a sealing surface 184a may be formed at one side of the boss portion 184 where the plug 171 contacts. The plug 171 may be located outside the case 110. The plug 171 has a larger width (or an outer diameter) than the discharge portion 182 and a width (or an outer diameter) smaller than that of the boss portion 184, 182, the plug 171 may be inserted into the boss portion 184.

The plug 171 may be formed of rubber or silicone to improve the sealing force with the discharging portion 182.

A valve shaft 172 is connected to one end of the plug 171.

The head 173 is connected at one end to the valve shaft 172 and has a width wider than the valve shaft 172 and can be located inside the case 110. [ Specifically, the head 173 can be positioned on the catching portion 181 of the discharge port 180. Preferably, the width of the head 173 may be greater than the width of the valve shaft 172 and the reservoir 181. That is, the width of the head 173 is formed to be larger than the width of the valve shaft 172, so that it is possible to provide a place where the elastic spring 174 inserted outside the valve shaft 172 is supported, The head 173 is caught by the lower surface 110c of the case 110 and can act as a stopper when the opening and closing valve 170 reciprocates upward and downward . Of course, the head 173 also prevents foreign matter from flowing into the collecting part 181. [

The head 173 may further include a plurality of inflow preventing pieces 175 for preventing foreign substances having a predetermined size or more from entering. The inflow preventing pieces 175 may be disposed around the head 173 and may extend from the head 173 toward the catching portion 181 as shown in Fig. That is, a plurality of the head 173 may be spaced apart from each other on the lower surface of the head 173. The distance between the adjacent inflow preventing pieces 175 may be adjusted to control the size of the foreign object to be prevented from flowing into the catching part 181. [

When the opening / closing valve 170 reciprocates, the inflow preventing piece 175 reciprocates inside the collecting part 181 and can perform the guiding function concurrently.

The head 173 may contact the lower surface of the drawer 120 when the drawer 120 moves. Specifically, when the drawer 120 moves, the lower surface of the storage portion 123 comes into contact with the head 173, so that the head 173 is pressed. When the head 173 is pressed, the on-off valve 170 is opened.

The upper surface of the head 173 has a round shape protruding upward so that friction with the drawer 120 can be minimized when the drawer 120 moves.

The valve shaft 172 connects the plug 171 and the head 173 and is disposed through the outlet 180. That is, the valve shaft 172 reciprocates within the discharge port 180, and reciprocates the plug 171 and the head 173 connected to one end and the other end. Therefore, the reciprocating motion of the head 173 is transmitted to the plug 171 through the valve shaft 172. [

More specifically, the valve shaft 172 has a width smaller than that of the head 173 and the plug 171, and has a collecting section 181 and a discharging section 182 so as to pass through the collecting section 181 and the discharging section 182 182) width (or inner diameter).

And is provided inside the discharge port 180 of the elastic spring 174 to apply an elastic force to the reciprocating motion of the opening / closing valve 170. More specifically, one end of the elastic spring 174 is in contact with the head 173, and the other end is in contact with the step between the puddle portion 181 and the discharge portion 182. Further, the elastic spring 174 is located inside the catching portion 181. [ The resilient spring 174 provides a restoring force that causes the opening and closing valve 170 to be restored to the inside of the case 110.

13 and 14, the operation of the on-off valve will be described as follows.

Referring to FIG. 13, the plug 171 and the discharge portion 182 are initially closed by the elastic force of the elastic spring 174. Accordingly, the vacuum state inside the case 110 is maintained.

14, when an external force (for example, contact of the drawer 120) is applied to the head 173, the head 173 moves downward and the valve shaft 172 and the plug 171 are moved downward Direction. At this time, while the plug 171 is separated from the discharging portion 182, the water inside the case 110 is discharged through the discharging portion 182.

16 and 17 are explanatory diagrams illustrating the operation of the on-off valve according to an embodiment of the present invention.

16 is a cross-sectional view showing a state in which the case 120 is closed by the case 110. Fig.

16, the drawer 120 is formed so that the lower surface of the drawer 120 and the head 173 can be in contact with each other when the drawer 120 is moved. Specifically, when the lower surface of the storage portion 123 of the drawer 120 moves, when the head 173 is brought into contact with the lower surface of the storage portion 123, the head 173 is pressed to open the opening / closing valve 170.

A pressing portion 124 may be further formed on the lower surface of the drawer 120 (specifically, the lower surface of the receiving portion 123) to be in contact with the head 173. The pusher 124 contacts the head 173 when the drawer 120 moves, and presses the head 173. The pressing portion 124 may protrude downward from the receiving portion 123.

Initially, the case 110 is closed by the drawer 120, and the inside of the case 110 becomes a vacuum state. The opening and closing valve 170 maintains a closed state (a state in which the plug 171 seals the discharge portion 182) by the elastic force of the elastic spring 174. [

17 is a sectional view showing a state in which the drawer 120 is opened in the case 110. Fig.

The drawer 120 is opened while the vacuum state inside the case 110 is released. At this time, the drawer 120 is moved in the forward direction of the case 110, and the presser portion 124 presses the head 173 of the open / close valve 170.

When the head 173 is pushed, the plug 171 is spaced apart from the discharge portion 182, so that the water stored in the water collecting portion 181 is discharged to the outside of the case 110.

Therefore, in the embodiment, since the discharge port 180 is sealed by the opening / closing valve 170 by the elastic force of the elastic spring 174 in the normal state, the vacuum state inside the case 110 is maintained, The opening / closing valve 170 is automatically opened to open the case 110, so that the water generated inside the case 110 can be discharged to the outside.

In addition, the embodiment has a simple structure and has an advantage that water generated in the case 110 can be discharged by a simple operation of opening and closing the drawer 120 without any other control.

Fig. 18 is a view showing the extent of deformation of the case according to the comparative example, and Fig. 19 is a diagram showing deformation degree of the case according to the embodiment.

18 shows the degree of deformation when a negative pressure is formed inside the case 110 according to the comparative example. The edge of the opening 113 is deformed by the negative pressure inside the case 110. [ In particular, a large deformation of 13.22 mm occurs at the center of the upper surface of the rim of the opening 113. In this case, the contact between the flange 119 and the drawer 120 is released from the opening 113, and outside air is introduced into the case 110. Therefore, it is difficult to keep the inside of the case 110 in a negative pressure state.

19 shows the degree of deformation when the negative pressure is formed inside the case 110 according to the embodiment. Only a small deformation of about 1.5 mm is generated in the center of the upper surface of the rim of the opening 113 at the same negative pressure as in the comparative example. Thus, the contact between the flange 119 and the drawer 120 is maintained in the opening 113, and external air is prevented from entering the interior of the case 110. As a result, the inside of the case 110 can be kept in a negative pressure state, and the vegetables and the like stored in the case 110 can be stored freshly.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It should be understood that various modifications may be made by those skilled in the art without departing from the spirit and scope of the present invention.
