[0001] The present invention relates to a vacuum-sealed food storage device for a refrigerator, and more particularly, to a vacuum-sealed food storage device for a refrigerator that forms a vacuum in a storage compartment itself for storing various foods such as vegetables and meat in a refrigerator and then automatically maintains the vacuum, thereby eliminating the hassle of having to vacuum-pack each food item, senses the vacuum level of the storage compartment and accurately informs the user of the vacuum level, can selectively control the vacuum level, and supplies light to enable photosynthesis in vegetables stored in a vacuum state in the storage compartment, thereby maintaining the freshness of the vegetables.

[0002] In general, a refrigerator is an electrical appliance that uses a refrigerant cycle to maintain the temperature of the storage compartment at above or below freezing, and can store food in the refrigerator or freezer.

[0003] Looking at the general configuration of a refrigerator, it includes a main body that forms a storage space for storing food, and a door that is arranged to be rotatable or slidable on the main body to open and close the storage space.

[0004] Meanwhile, most food products with a short shelf life or that are easily spoiled are generally vacuum-packed in plastic bags and distributed for hygiene, safety, and convenience of handling.

[0005] Accordingly, vacuum-packed food can be stored safely for a longer period of time than regular packaged food in general homes or businesses. However, food that has been opened and taken out of a vacuum packaging can easily spoil or become damaged due to the infiltration of microorganisms in the air if not completely consumed. In addition, even if opened food is stored in a refrigerator, its freshness quickly declines, and the smell of the food can become a factor that hinders a pleasant refrigerator environment.

[0034] FIG. 1 is a front view showing a vacuum sealed food storage device for a refrigerator according to a first embodiment of the present invention applied to a refrigerator compartment, FIG. 2 is a perspective view showing a vacuum sealed food storage device for a refrigerator according to a first embodiment of the present invention, FIG. 3 is a side cross-sectional view showing a vacuum sealed food storage device for a refrigerator according to a first embodiment of the present invention applied to a refrigerator compartment, and FIG. 4 is a plan cross-sectional view showing another embodiment of a storage unit and a vacuum unit applied to a vacuum sealed food storage device for a refrigerator according to the first embodiment of the present invention.

[0035] A vacuum sealed food storage device (100) for a refrigerator according to the first embodiment of the present invention is a technology that can store various types of food to be stored in a refrigerator by creating a vacuum state at once and automatically maintaining the vacuum level.

[0036] To this end, the vacuum sealed food storage device (100) for a refrigerator according to the first embodiment of the present invention may include at least one of a storage unit (110), a vacuum unit (120), a vacuum release knob (130), a dehumidifying filter (140), a sensor unit (150), a display unit (160), a vacuum level control button (170), a connector (180), a photosynthetic unit (190), and a timer (191).

[0037] The storage section (110) is stored in a sliding manner in the internal storage compartment (10a) of the storage unit (10) provided in the refrigerator.

[0038] At this time, the storage unit (10) is provided at the bottom of the refrigerator compartment of a general refrigerator (1) and is used as a refrigerated storage compartment for storing food such as vegetables, meat, fish, and other various foods.

[0039] Since the storage unit (10) is a commercialized configuration of a general refrigerator (1), a detailed description is omitted.

[0040] The storage unit (110) can be formed in a box shape with an opening formed on the upper surface for food to enter and exit and a storage space formed inside for storing food.

[0041] A handle (112) is formed on the front of the storage unit (110).

[0042] The handle (112) can be formed into a groove or a bar shape having a cross-sectional shape roughly in the shape of the letter 'ㄱ'.

[0043] The storage unit (110) can be inserted into the storage room (10a) or withdrawn from the storage room (10a) by holding the handle (112) and pushing or pulling it.

[0044] A packing (30) is installed along the edge of the front part (111) that constitutes the storage part (110) to maintain the storage space in a vacuum state in contact with the surface facing the front part (12) of the storage unit (10).

[0045] The packing (30) can be formed into a roughly square frame shape. In addition, the packing (30) can be formed of a rubber or silicone material having excellent packing power.

[0046] When the storage unit (110) is inserted into the storage room (10a), the packing (30) is pressed against the front of the storage unit (10) to seal the storage space.

[0047] As a result, when the vacuum unit (120) described below discharges the air present in the storage space, the storage space maintains a vacuum state. As a result, various food items stored in the storage space can be stored in a vacuum state.

[0048] The vacuum section (120) forms vacuum pressure by discharging air existing in the storage space, and can be formed using a vacuum pump.

[0049] For example, the vacuum unit (120) can be installed on the ceiling surface (11) of the storage unit (10).

[0050] The discharge line (121) of the vacuum section (120) is installed through the ceiling surface (11) of the storage section (110) or the storage cabinet (10).

[0051] At this time, a power switch (20) is formed in the storage unit (10) to supply power to or cut off power to the vacuum unit (120).

[0052] When the power switch (20) is pressed to operate the vacuum unit (120), the air present in the storage space is discharged to the outside of the storage unit (10) through the exhaust line (121).

[0053] That is, the vacuum unit (120) forcibly discharges the air existing in the storage space to create a set vacuum pressure in the storage space.

[0054] At this time, the storage space forms a vacuum pressure by reducing atmospheric pressure and moisture by the vacuum unit (120). As a result, various food items stored in the storage space can be stored in a vacuum state.

[0055] The vacuum unit (120) can be operated by receiving commercial power in the same way as an electronic device typically installed in a refrigerator (1).

[0056] As another example, the vacuum unit (120) may be installed in an installation chamber (13a) formed in the refrigerator body (13) as illustrated in FIG. 3, and may forcibly discharge air present in the storage space through a suction operation. In this case, an intake hose (122) that penetrates the installation chamber (13a) and is received in the storage space may be installed in the vacuum unit (120). In this case, the discharge line (121) may be located in the installation chamber (13a) together with the vacuum unit (120).

[0057] Meanwhile, a vacuum release knob (130) is installed through the front part (111) of the storage unit (110).

[0058] The vacuum release knob (130) is configured to release the vacuum pressure formed in the storage space so that the storage section (110) can be withdrawn.

[0059] A certain area of ​​the vacuum release knob (130) protrudes from the front part (111) of the storage part (110). Accordingly, if the user wishes to release the vacuum in the storage space, he or she can simply pull the vacuum release knob (130).

[0060] The vacuum release knob (130) moves toward the storage space to seal the space when the storage space is maintained in a vacuum state by the operation of the vacuum unit (120). In this sealed state, when the user pulls the vacuum release knob (130), air is introduced into the storage space. This releases the vacuum in the storage space.

[0061] That is, when the storage unit (110) maintains a vacuum state, the storage unit (110) inserted into the storage room (10a) cannot be withdrawn due to strong vacuum pressure.

[0062] Accordingly, if you wish to take out food stored in the storage unit (110), press the power switch (20) to stop the operation of the vacuum unit (120), then pull the vacuum release knob (130) to release the vacuum by introducing air into the storage space. Then, pull the handle (112) to withdraw the storage unit (110) and take out the desired food.

[0063] Meanwhile, after taking out the desired food, push the storage unit (110) to put it back into the storage room (10a), and then press the power switch (20) to operate the vacuum unit (120).

[0064] When the vacuum unit (120) is operated, the air existing in the storage space is discharged to the outside, and the vacuum release knob (130) moves toward the storage space to achieve a sealed state.

[0065] The storage space is again maintained in a vacuum state by the operation of this vacuum part (120) and the principle of sealing by the vacuum release knob (130).

[0066] At this time, since the vacuum release knob (130) is a commercialized configuration, a description of its specific operation and function is omitted.

[0067] Meanwhile, the dehumidifying filter (140) is configured to prevent moisture from being sucked into the vacuum section (120).

[0068] A dehumidifying filter (140) can be installed on the air intake side of the vacuum unit (120).

[0069] The dehumidifying filter (140) absorbs moisture mixed in the air sucked in by the vacuum unit (120). This prevents moisture from being sucked into the vacuum unit (120), thereby preventing the lifespan of the vacuum unit (120) from being shortened.

[0070] The sensor unit (150) can be formed as a vacuum sensor to sense the vacuum level of the storage space.

[0071] The sensor unit (150) is installed on the ceiling surface (11) of the storage unit (10) or the inner wall surface of the storage unit (110) to sense the vacuum level of the storage space.

[0072] The sensor unit (150) senses the vacuum level of the storage space and transmits the sensed vacuum level to the control unit.

[0073] And, the control unit controls the vacuum level of the storage space sensed by the sensor unit (150) to be displayed on the display unit (160), and controls the vacuum unit (120) to maintain vacuum in the storage space.

[0074] The display unit (160) can be installed in the storage unit (10).

[0075] The display unit (160) may be formed of a liquid crystal. The display unit (160) displays the vacuum level (vacuum strength) of the storage space detected by the sensor unit (150) in numbers according to the control of the control unit, thereby allowing the user to visually check the vacuum level of the storage space and confirm the vacuum maintenance status.

[0076] The vacuum level control button (170) can be installed in the storage unit (10). The vacuum level control button (170) is electrically connected to the vacuum unit (120).

[0077] The vacuum level of the storage space can be adjusted to weak, strong, or medium by adjusting the vacuum force of the vacuum unit (120) using the vacuum level adjustment button (170).

[0078] For example, the vacuum level control button (170) may include a weak button (171) for setting the vacuum level of the storage space to weak, a medium button (172) for setting it to medium, and a strong button (173) for setting it to strong.

[0079] The vacuum level of the vacuum section (120) can be adjusted through the weak button (171), medium button (172) and strong button (173) to set the vacuum level of the storage space in various ways.

[0080] As another example, although not shown in the drawing, the vacuum level control button (170) may include a + button for increasing the vacuum level of the storage space and a - button for decreasing the vacuum level of the storage space. That is, the more the + button is pressed, the stronger the vacuum level becomes, and the more the - button is pressed, the weaker the vacuum level becomes.

[0081] As another example, although not shown in the drawing, a dial-type button may be used instead of the vacuum level control button (170). The vacuum level gradually increases as the dial-type button is turned to the right, and the vacuum level gradually decreases as the dial-type button is turned to the left.

[0082] In the past, when storing food in a vacuum state in a storage unit (110), there was the inconvenience of having to individually vacuum-pack the food, but the vacuum-sealed food storage device (100) for a refrigerator according to the first embodiment of the present invention can store all food stored in the storage unit (110) in a vacuum state at once by making the storage space of the storage unit (110) itself into a vacuum state. This can prevent the inconvenience of having to individually vacuum-pack the food.

[0083] Next, another embodiment of the storage unit (110) and the vacuum unit (120) will be described with reference to FIG. 4.

[0084] At this time, the aforementioned FIGS. 1 to 3 illustrate examples in which a storage room (10a) and a storage section (110) are applied as one each, and FIG. 4 illustrates an example in which a storage room (10a) and a storage section (110) are applied as multiple units.

[0085] Referring to Fig. 4, the storage room (10a) can be divided into at least two or more by a partition wall (14).

[0086] And, the storage section (110) is applied in the same number as the storage room (10a).

[0087] Accordingly, the storage units (110) are stored in a withdrawable manner in each storage room.

[0088] The vacuum section (120) is installed in the installation room (13a) formed in the refrigerator body (13) instead of the ceiling surface of the storage unit (10).

[0089] At this time, the installation room (13a) may be a space where an air compressor is installed in a typical refrigerator.

[0090] The connector (180) includes a connecting pipe (181) connected to the vacuum section (120) and a pair of branch pipes (182) connected to the connecting pipe (181).

[0091] The intake pipes (192) are each connected to the branch pipes (182). The intake pipes (192) pass through the installation room (13a) and are each positioned in the storage space of the storage unit (110) stored in the storage unit.

[0092] At this time, the intake pipe (192) can be formed of a tube material.

[0093] When the vacuum unit (120) operates, air existing in the storage space is sucked in through the intake pipe (192). At this time, the air sequentially passes through the intake pipe (192), the branch pipe (182), and the connecting pipe (181) and then is sucked into the vacuum unit (120).

[0094] Through the structure that connects the connector (180) and the intake pipe (192) to the vacuum unit (120), air can be discharged simultaneously from two or more independent storage spaces to create a vacuum state.

[0095] At this time, the aforementioned dehumidifying filter (140) is installed at the end of the intake pipe (192) and can be located in the storage space.

[0096] Meanwhile, the photosynthetic unit (190) is installed on the ceiling surface of the storage unit.

[0097] The photosynthetic unit (190) irradiates light for photosynthesis to plants stored in the storage room (10a).

[0098] At this time, the photosynthetic unit (190) can be applied as any one selected from among LED, light-emitting diode, white fluorescent lamp, and incandescent lamp.

[0099] For example, the photosynthetic unit (190) can output a wavelength between 450 and 650 nm, which is a wavelength of light suitable for photosynthesis.

[0100] A timer (191) is installed in the storage cabinet. The timer (191) is electrically connected to the photosynthetic unit (190).

[0101] The time at which power is supplied to the photosynthetic unit (190) can be selectively controlled through a timer (191).

[0102] Through this timer (191), the photosynthetic unit (190) can be operated repeatedly for about 1 to 6 hours at intervals of about 1 to 6 hours.

[0103] In this way, by controlling the operating time of the photosynthetic unit (190), light and dark reactions can be alternately supplied to the plants, thereby preventing the freshness of green plants such as vegetables stored in the storage unit (110) from being impaired and extending the preservation period.

[0104] For example, the timer (191) may further include a liquid crystal display for displaying the set time. In this case, the liquid crystal display may be installed in the storage cabinet (10).

[0105] As another example, the timer (191) can be electrically connected to the display unit (160). Accordingly, the time set through the timer (191) can be displayed on the display unit (160).

[0106] The vacuum sealed food storage device (100) for a refrigerator according to the first embodiment of the present invention described above and the vacuum sealed food storage device (200) for a refrigerator according to the second embodiment described below can be applied to a two-door type refrigerator in which a freezer and a refrigerator are formed to be separated in the left and right directions, as illustrated in FIG. 1, and although not illustrated in the drawing, can also be applied to a two-door type refrigerator in which a freezer and a refrigerator are formed to be separated in the vertical directions. In addition, it can also be applied to a one-door type refrigerator in which a refrigerator and a freezer are formed in the vertical directions in one space.

[0107] Next, a vacuum sealed food storage device for a refrigerator according to a second embodiment of the present invention will be described with reference to FIGS. 5 and 6.

[0108] FIG. 5 is a perspective view illustrating a vacuum-sealed food storage device for a refrigerator according to a second embodiment of the present invention, and FIG. 6 is a cross-sectional view illustrating a vacuum-sealed food storage device for a refrigerator according to a second embodiment of the present invention.

[0109] As shown in FIGS. 5 and 6, a vacuum sealed food storage device (200) for a refrigerator may include at least one of a storage section (210), a cover section (220), a vacuum section (230), a vacuum release knob (240), a dehumidifying filter (250), a battery section (260), a sensor section (270), a display section (280), a vacuum level control button (290), a photosynthesis section (300), and a timer (310).

[0110] The vacuum-sealed food storage device for a refrigerator according to the first embodiment described above is a type that is used without the storage compartment being completely withdrawn from the refrigerator, and the vacuum-sealed food storage device for a refrigerator according to the second embodiment can be defined as a type that is stored and stored in a refrigerator compartment by a user and can be completely withdrawn from the refrigerator compartment for a short time when necessary.

[0111] To this end, the storage unit (210) may be formed in a box shape with an opening formed on the upper surface for food to enter and exit and a storage space formed inside for storing food.

[0112] For example, the storage unit (210) can be stored in a form that is mounted on the upper surface of the storage unit (10).

[0113] As another example, the storage unit (210) may be inserted into the storage room (10a) in a sliding manner or may be withdrawn from the storage room (10a) in the same manner as the storage unit (110) described above.

[0114] The cover part (220) opens or closes the opening by being combined with or separated from the storage part (210).

[0115] The storage section (210) and the cover section (220) can be combined or separated in the same manner as a general airtight container or a Lock & Lock container.

[0116] A receiving groove is formed along the edge of the bottom surface of the cover portion (220) that faces the upper surface of the receiving portion (210) to receive the upper part of the receiving portion (210), and a packing (30) for sealing between the cover portion (220) and the receiving portion (210) is received inside the receiving groove.

[0117] When the cover part (220) is placed on the upper surface of the storage part (210), the upper part of the storage part (210) is received in the receiving groove and is in close contact with the packing (30), thereby forming a seal.

[0118] Since the combined structure of the storage section (210) and the cover section (220) is a technology commercialized in general airtight containers or Lock & Lock containers, a detailed description is omitted.

[0119] A handle (221) that the user holds is formed on the upper surface of the cover (220).

[0120] A power switch (20) is formed on the upper surface of the cover (220) to supply power to or cut off power to the vacuum portion (230).

[0121] The vacuum section (230) is configured to form vacuum pressure by discharging air from the storage space.

[0122] The vacuum section (230) can be formed by a vacuum pump.

[0123] For example, the vacuum unit (230) can be installed on the bottom surface of the cover unit (220) and accommodated in the storage space.

[0124] As another example, the vacuum unit (230) is coupled to the upper surface of the cover unit (220), and only the suction line (231) provided therein can pass through the cover unit (220) and be positioned in the storage space.

[0125] Since this vacuum part (230) is the same as the vacuum part (120) described above, a detailed description is omitted.

[0126] Additionally, a vacuum release knob (240) is installed vertically through the cover part (220).

[0127] The vacuum release knob (240) is applied in a different position compared to the above-described embodiment, but its function is the same, so a detailed description is omitted.

[0128] A dehumidifying filter (250) can be installed on the air intake side of the vacuum unit (230).

[0129] The dehumidifying filter (250) is located in the storage space and absorbs moisture mixed with the air sucked in by the vacuum unit (230). This prevents moisture from being sucked into the vacuum unit (230), thereby preventing the lifespan of the vacuum unit (230) from being shortened.

[0130] The battery section (260) can be installed on the upper surface of the cover section (220).

[0131] The battery section (260) is electrically connected to the vacuum section (230) to supply power.

[0132] The battery section (260) is formed of a secondary battery and can be repeatedly charged.

[0133] The battery section (260) includes a USB connection terminal (261) to which a conventional USB connection cable can be connected and a charging status indicator light (231).

[0134] Therefore, when the power of the battery unit (260) runs out, the battery unit (260) can be charged by connecting the USB connection cable to the USB connection terminal (261).

[0135] The sensor unit (270) senses the vacuum level of the storage space and can be installed on any one selected from the bottom surface of the cover unit (220), the inner wall surface of the storage unit (210), and the bottom surface of the storage unit (210).

[0136] The display unit (280) is installed on the upper surface of the cover unit (220).

[0137] Additionally, the vacuum control button (290) is installed on the upper surface of the cover (220).

[0138] The photosynthetic unit (300) is installed on the bottom surface of the cover unit (220) and irradiates light for photosynthesis to plants stored in the storage unit (210).

[0139] A timer (310) is provided to control the operating time of the photosynthetic unit (300).

[0140] The timer (310) can be installed on the upper surface of the cover (220) or the storage portion (110).
