Description

  Embodiments of the present invention relate to storage.

  As a storage method for maintaining the freshness of food, CA (Controlled Atmosphere) storage for adjusting the composition and pressure of air in the storage is known. As a CA storage system, a gas replacement system that replaces the air in the storage with a gas such as nitrogen or carbon dioxide, a vacuum system that depressurizes the storage using a vacuum pump, and a polymer electrolyte membrane provided on the inner and outer boundaries of the storage There are a polymer electrolysis system in which oxygen in the storage is discharged out of the storage by a chemical reaction generated in the above, an adsorption system in which oxygen is adsorbed by an oxygen adsorbent installed in the storage. In any system, the amount of oxygen that oxidizes the food and lowers its freshness can be reduced from the storage, and the food can be kept in a hypoxic state. It is known that CA storage is particularly effective in maintaining the freshness of vegetables.

  When performing CA storage, it is necessary to block the circulation of air outside the storage chamber in order to keep a specific storage chamber in the storage in a hypoxic state. However, every time the door of the storage chamber is opened, air having a reduced oxygen concentration enters the storage chamber, and the oxygen amount in the reduced oxygen storage chamber becomes equal to the oxygen amount of the outside air. In order to return the refrigeration chamber to the reduced oxygen state again, it is necessary to adjust the composition and pressure.

  An operation display unit 200 that displays the operating state of the refrigerator is provided on the front surface of the refrigerator compartment door 23. However, the position where the operation display unit 200 is provided may be the outer surface of the refrigerator, and is not limited to the front surface of the refrigerator compartment door 23.

  The opening of the vegetable compartment 24 is closed by a drawer-type vegetable compartment door 25 connected to the slide rail 28.

  Specifically, as shown in FIGS. 2 to 4, the slide rail 28 is provided on a pair of left and right support frames 28 a that are fixed to the back side of the vegetable compartment door 25 and extend in the front-rear direction, and on the left and right side walls of the vegetable compartment 24. The fixed rail 28b and an urging mechanism (not shown) for urging the support frame 28a backward are provided. The pair of left and right support frames 28a are supported so as to be slidable in the front-rear direction by fixed rails 28b provided on the left and right side walls of the vegetable compartment 24. Be forced.

  A pair of left and right support frames 28a support a box-shaped vegetable container 26 whose upper surface is open. As a result, the vegetable container 26 is supported by the support frame 28a and the fixed rail 28b constituting the slide rail 28 so as to be slidable in the front-rear direction. The vegetable container 26 is housed in the cabinet as it is pulled out and the vegetable compartment door 25 is closed. A push-type door switch 25a is provided at a position facing the vegetable compartment door 25 of the refrigerator body 12, and detects whether the vegetable compartment door 25 is in an open state or a closed state. Based on the result of opening of the vegetable compartment door 25 detected by the door switch 25a, the time when the vegetable compartment door 25 is opened frequently by the control unit 13a is calculated.

  A CA storage chamber 27 is provided above the vegetable container 26 in a state of hanging from the partition 21. The CA storage chamber 27 includes a main body 27a having a front opening 27c, a lid 27b for opening and closing the front opening 27c, and an internal food container 29 accommodated in the main body 27a.

  The shape of the main body 27a is a flat rectangular parallelepiped that is longer in the width direction and the depth direction than in the height direction. The main body 27a is preferably molded integrally with the lower surface of the partition 21 and fixed in the vegetable compartment 24, but may not be integrally molded. An annular groove 29e is provided at the peripheral edge portion 29c of the front opening 27c so as to surround the opening, and an annular seal packing 29d is fitted into the groove 29e.

  The internal food container 29 has a box shape with an upper surface opened, and food can be taken in and out from the opening. In addition, the inner food container 29 is provided with a lid 27b detachably in front of it, and can slide back and forth in the CA storage chamber 27 with the lid 27b attached. A recess 29b-1 is formed in the center of the front surface of the lid 27b as shown in FIG. 7, and a handle 29b-2 is provided so as to cover approximately half above the recess 29b-1.

  As shown in FIGS. 7 and 8, locks 90a and 90b are provided above and below the front opening 27c of the main body 27a around shafts 91a and 91b provided along the upper outer side and the lower outer side of the front opening 27c. It is provided so that rotation is possible. The locks 90a and 90b have protrusions 92a and 92b that are tapered so that the cross-sectional shape becomes narrower toward the tip. When the locks 90a and 90b are retracted to the outside of the front opening 27c and the lid 27b is pressed against the front opening 27c of the main body 27a, the lid 27b contacts the sealing packing 29d. In this state, the upper lock 90a is rotated downward and the lower lock 90b is rotated upward, and the respective protrusions 92a and 92b are engaged with the front surface of the lid 27b. At this time, since the cross-sectional shape of the protrusions 92a and 92b is a taper shape that narrows toward the tip, the protrusions 92a and 92b can be engaged with the front surface of the lid 27b without extremely deforming the protrusions 92a and 92b. it can. Thus, the lid 27b is pressed against the peripheral edge 29c of the front opening 27c by the projection 92, and is fixed to the front opening 27c of the main body 27a and locked. The locks 90a and 90b are automatically rotated by driving a motor (not shown) that receives a command from the control unit 13a to lock and release the lock.

  As shown in FIG. 7, the lower end of the lid 27 b is supported by the upper end portions 26 a of the left and right side walls of the vegetable container 26. Thereby, the lid | cover 27b can slide on the upper end part 26a of the side wall of the vegetable container 26 pulled out previously in the front-back direction. The internal food container 29 attached to the lid 27b is supported by the vegetable container 26 via the lid 27b, and can slide on the vegetable container 26 in the front-rear direction together with the lid 27b. A mechanism for reducing friction such as a roller may be provided on one of the lower end of the lid 27b or the side wall upper end portion 26a of the vegetable container 26 so that the lid 27b can move back and forth more smoothly on the upper end portion 26a. .

  When the internal food container 29 is taken out from the CA storage room 27, the vegetable room door 25 is first opened. At this time, the vegetable container 26 is pulled out together with the opening operation of the vegetable compartment door 25 as described above, but the opening and opening of the CA storage chamber 27 are opened and the vegetable container 26 is opened. The CA storage room 27 remains sealed with the front opening 27c closed by the lid 27b even when the vegetable door 25 is opened (see FIG. 4). From this state, when the locks 90a and 90b are removed and the handle 29b-2 of the lid 27b is pulled forward, the CA storage chamber 27 is hermetically sealed and the internal food container 29 attached to the lid 27b is supported by the vegetable container 26. Then go forward (see Fig. 3). When the inner food container 29 is pulled out to the end, it can be separated from the CA storage chamber 27 and taken out. Conversely, when the internal food container 29 is stored in the CA storage chamber 27, the internal food container 29 is pushed into the CA storage chamber 27, and the lid 27b attached to the internal food container 29 is attached to the sealing packing. The front surface opening 27c of the main body 27a is closed by the lid 27b, and is locked by the locks 90a and 90b. In this way, the CA storage chamber 27 is in a sealed state by blocking the inflow of ambient air.

  On the other hand, as shown in FIG. 5, an opening 27 d that opens rearward and a rib 35 that protrudes into the CA storage chamber 27 are provided on the back surface of the CA storage chamber 27.

  The opening 27d is composed of a plurality of through holes 27d-1 penetrating the back surface of the CA storage chamber 27. For example, a plurality of slit-like through holes 27d-1 elongated in the vertical direction are provided side by side in the horizontal direction. It has been. The through hole 27d-1 constituting the opening 27d may be a circular hole or a square hole in addition to the slit shape as described above.

  The ribs 35 protruding from the back surface of the CA storage chamber 27 can be, for example, protrusions provided on both left and right sides of the opening 27d and extending vertically from the bottom surface of the CA storage chamber 27. The shape is not particularly limited, and for example, the rib 35 may be provided so as to surround the opening 27d.

  An ice making room (not shown) equipped with an automatic ice making device and a first freezing room 44 are provided on the left and right sides of the freezing space 40 disposed below the vegetable room 24 via the heat insulating partition wall 14. Is provided with a second freezer compartment 46.

  The ice making chamber, the first freezing chamber 44, and the second freezing chamber 46 are also closed by the drawer-type doors 45 and 47, and the left and right pairs fixed to the back side of the doors 45 and 47, like the vegetable chamber 24. The storage container is held by the support frame, and the storage container is pulled out of the storage as the door is opened.

  A refrigeration cooler 52 and a refrigeration fan 53 for cooling the air in the refrigeration space 20 are provided on the rear surface of the refrigeration space 20. The air cooled by the refrigeration cooler 52 passes through the duct 37. The air is sent to the refrigerator compartment 22 to cool the refrigerator compartment 22. The air flowing through the refrigerator compartment 22 flows into the vegetable compartment 24 through a through hole (not shown) provided in the partition body 21, cools the vegetable compartment 24, and then takes in the return duct 31 provided on the back of the vegetable compartment 24. Then, the refrigeration cooler 52 returns.

  As shown in FIG. 2, below the refrigeration cooler 52, a jar 56 that receives defrost water generated by defrosting of the refrigeration cooler 52 is provided. Is provided. The trough 56 and the oxygen reduction device 60 are connected by a hose 57, and defrost water received by the trough 56 is supplied to the oxygen reduction device 60 through the hose 57.

  On the back surface of the freezing space 40, a freezing cooler 54 that cools the air in the freezing space 40, and the air cooled by the freezing cooler 54 is sent to the ice making room, the first freezing room 44, and the second freezing room. A freezing fan 55 is provided.

  The refrigeration cooler 52 and the refrigeration cooler 54 constitute a refrigeration cycle together with the compressor 32, the condenser (not shown) and the switching valve (not shown) provided at the lower back of the refrigerator body 12. Each of the storage chambers provided in the refrigeration space 20 and the refrigeration space 40 is cooled to a predetermined temperature by controlling the refrigeration fan 53 and the refrigeration fan 55.

  As shown in FIG. 6, the oxygen reduction device 60 is housed and unitized in a case 64 in a state where a plate-like solid polymer electrolyte membrane 61 is sandwiched between an anode electrode 62 and a cathode electrode 63. When a voltage is applied between 62 and the cathode electrode 63, hydrogen ions generated by decomposing defrosted water or moisture in the air supplied from the trough 56 through the hose 57 at the anode electrode 62 are converted into the anode electrode 62. It moves to the cathode electrode 63 side from the side, passes through the opening 27d of the CA storage chamber 27 from the opening 65 provided in the case 64, reacts with oxygen in the CA storage chamber 27, and generates water, thereby generating CA. Oxygen in the storage chamber 27 is reduced.

  The oxygen reduction device 60 is provided inside the return duct 31 so that the cathode electrode 63 faces the opening 27 d of the CA storage chamber 27 through the opening 65 provided in the case 64.

  The oxygen reduction device 60 operates while avoiding a time zone in which the vegetable room door 25 having the CA storage room 27 is frequently opened. That is, when the opening of the vegetable compartment door 25 is detected a predetermined number of times or more by the door switch 25a in a preset time zone, for example, when the user opens the vegetable compartment door 25 twice or more within one hour. It is determined that it is a time zone when the vegetable room door 25 is opened many times. The oxygen reduction device 60 is not operated during the time when the number of times of opening the door is large, and the lock of the lid 27b by the locks 90a and 90b is released so that the user can freely open the CA storage chamber 27. After a predetermined time (for example, 1 hour) elapses in this time zone, the operation of the oxygen reduction device 60 is started. In addition, since the oxygen reduction device 60 starts operation before a predetermined time (for example, 30 minutes) before the operation of the oxygen reduction device 60 starts, the operation that the CA storage chamber 27 cannot be opened for a while is operated. It is displayed on the display unit 200, and after the oxygen reduction device 60 actually starts operation, the operation display unit 200 displays that the oxygen reduction device 60 is in an operating state.

  On the other hand, if the number of times the door switch 25a detects the opening of the vegetable room door 25 in the preset time zone is less than the predetermined number of times, the vegetable room door 25 is judged to be a time zone when the door opening frequency is low. The lid 27b is locked by the locks 90a and 90b, and the operation of the oxygen reduction device 60 is started.

  Furthermore, the locks 90a and 90b are locked almost simultaneously with the start of the operation of the oxygen reduction device 60 to prevent the user from opening the CA storage chamber 27, and the CA storage chamber 27 is locked. This is displayed on the operation display unit 200 having a function as a lock notification unit.

  The locks 90a and 90b maintain the locked state until the predetermined time (for example, 4 hours) elapses after the operation of the oxygen reduction device 60 is ended and the operation is ended. Then, after a predetermined time has elapsed, the locks 90a and 90b are automatically released so that the user can freely open the CA storage room 27, and the stored items stored in the CA storage room 27 are stored in the operation display unit 200. Display that it is stored in a hypoxic state.

  When the user wants to open the CA storage room 27 in a locked state, the lock is released by turning on the unlock button 201 provided on the operation display unit 200. On the other hand, when the lock is accidentally released or when it is desired to keep the lock after the lock is automatically released, the lock can be made effective by turning on the lock button 202. Note that the lock release button 201 provided on the operation display unit 200 is provided at a position that is at least a height that cannot be reached by an infant, such as an upper part of the refrigerator 10.

  Accordingly, when the user intends to open the CA storage chamber 27, the lock is released so that the CA storage chamber 27 can be opened, so that the user can easily open the CA storage chamber 27 when the amount of oxygen in the CA storage chamber 27 is small. Opening can be prevented.

  In addition, after the operation of the oxygen reduction device has been completed normally and the storage in the oxygen reduction state has been completed after a predetermined time has elapsed, the lock is automatically released, so that the user does not need to be locked. Since it is not necessary to release the lock, it is easy to use.

  Further, since the lid 27b of the CA storage chamber 27 is pressed against the main body 27a by performing the lock, the sealing performance is improved, and it is more sure that the air flows from the outside of the CA storage chamber 27 to increase the oxygen concentration. Can be prevented.

  Moreover, in order to operate the oxygen reduction apparatus 60 avoiding the time zone when the vegetable room 24 which is the storage room provided with the CA storage room 27 is frequently opened, the user takes out the stored items in the CA storage room 27 or CA When the stored product is desired to be stored in the storage chamber 27, the oxygen reduction device 60 is in operation, so that it is possible to prevent a situation where the device is locked and cannot be taken out or stored.

  Further, the oxygen reduction device 60 is operated when it is desired to store the stored product in the CA storage chamber 27 in order to notify the oxygen storage device 60 to start the operation before a predetermined time before the operation of the oxygen reduction device 60 starts. Therefore, it is possible to prevent a situation in which it is locked and cannot be taken out or stored.

  In addition, since the user can check the operation display unit 200, it can be easily determined whether or not the oxygen reduction device 60 is operating and whether or not the locks 90a and 90b are functioning. It is possible to prevent the CA storage chamber 27 from being opened by mistake.

  In addition, since the unlock button 201 is provided at a height that is not reachable by the infant, it is possible to prevent the infant from releasing the lock and opening the CA storage room 27 due to mischief or the like.

  Moreover, the opening of the vegetable compartment 24 and the opening of the lid 27b of the CA storage compartment 27 are performed independently, and even if the vegetable compartment 24 is opened, the sealing of the CA storage compartment 27 is not opened. Therefore, even if the vegetable compartment door 25 is frequently opened for taking in and out food inside the vegetable container 26 of the vegetable compartment 24, the oxygen amount inside the CA storage compartment 27 can be kept low. Therefore, it is not necessary to operate the oxygen reduction device 60 every time the vegetable compartment 24 is opened, and the power consumption can be suppressed.

  In addition, since the CA storage room 27 is provided above the vegetable container 26 inside the vegetable room 24, it is possible to effectively utilize a space that is difficult to use inside the vegetable room 24. In addition, since the internal food container 29 having an open upper surface is provided in the CA storage chamber 27 so that it can be pulled out, the food in the CA storage chamber 27 can be obtained even if the CA storage chamber 27 is disposed above the vegetable container 26. It is easy to take out and does not spoil usability. Furthermore, by providing the CA storage chamber 27 integrally with the partition body 21, parts can be shared, and the inside of the vegetable chamber 24 can be further effectively used.

  Moreover, since the CA storage room 27 is provided in the vegetable room 24, it can mainly be used for the storage of vegetables with a high effect by CA storage. Furthermore, since the inside of the vegetable compartment 24 is relatively hot in the refrigerated space 20, foods that are susceptible to low temperature damage such as eggplants and bananas can be stored in a reduced oxygen state without deteriorating the quality.

  In addition, by providing the CA storage chamber 27 integrally with the partition body 21, the CA storage chamber 27 itself to which the oxygen reduction device 60 is fixed cannot be pulled out, so that the user touches the oxygen reduction device 60 and breaks it. Can be prevented. Furthermore, since the internal food container 29 is removable from the CA storage chamber 27, the internal food container 29 can be taken out and washed.

  In addition, since the CA storage chamber 27 is hermetically sealed at the front surface, in the case of the CA storage chamber 27 that is a flat rectangular parallelepiped that is longer in the width direction and the depth direction than in the height direction, the entire upper surface is opened. As compared with the above, the opening area can be reduced, and the possibility of hindering sealing can be reduced.

  In the first embodiment described above, the case where the lid 27b is fixed to the main body 27a with the locks 90a and 90b as an example of the locking mechanism that prevents the lid 27b of the CA storage chamber 27 from being opened has been described. The opening of the lid 27b may be prevented from being displayed on the display 200, or the opening of the lid 27b may be prevented by using a speaker, or the opening of the lid 27b may be prevented by outputting a sound prohibiting the opening of the lid 27b.

  Moreover, although the case where the operation display unit 200 always displays whether the CA storage room 27 is in the locked state has been described in the first embodiment described above, the vegetable room including the CA storage room 27 is described. You may display whether it is locked only when 24 vegetable compartment doors 25 are opened. Or it is good also as a structure which alert | reports whether it is locked by the sound using a speaker as a lock | rock alerting | reporting means instead of displaying a speaker in a storage and displaying on the operation display part 200. FIG. According to this, since the vegetable compartment door 25 of the vegetable compartment 24 which is a storage compartment provided with the CA storage compartment 27 is closed and the CA storage compartment 27 is not opened, the lock state is not notified. Electric power can be reduced.

Second embodiment

  The storage of the second embodiment is different in that locking is not performed by locking 90a, 90b but by depressurizing the CA storage chamber 27.

  In the second embodiment, a vacuum pump for changing the pressure in the CA storage chamber 27 is provided, and when locking is desired, the air in the CA storage chamber 27 is sucked by the vacuum pump to reduce the pressure. As a result, due to the pressure difference generated inside and outside the CA storage chamber 27, the CA storage chamber 27 is locked because it receives pressure from the outside toward the inside. On the other hand, when it is desired to release the lock, the air can be pressurized by sending air into the CA storage chamber 27 by a vacuum pump, and the pressure can be reduced to the same level as the outside of the CA storage chamber 27, thereby enabling the opening. And

  Thus, as in the first embodiment, when the user intends to open the CA storage chamber 27, the lock due to the pressure difference is released to enable the opening, so that the oxygen amount in the CA storage chamber 27 is small. It is possible to prevent the user from opening the CA storage room 27 easily.

  Further, in the operation state of the oxygen reduction device 60, since the pressure reduction operation by the vacuum pump is performed at the same time, the oxygen amount in the CA storage chamber is reduced to a lower oxygen amount more quickly and less than when only the oxygen reduction device 60 is operated. Therefore, it is possible to more effectively receive the effect of maintaining the freshness of stored goods due to oxygen reduction.

  In the second embodiment, the case where a vacuum pump is provided instead of the locks 90a and 90b has been described as an example. However, a lock may be provided using a vacuum pump in addition to the locks 90a and 90b.

  Thereby, since the airtightness of the oxygen-reducing chamber 27 can be further improved, it is possible to prevent the oxygen concentration from increasing due to the inflow of air into the oxygen-reducing chamber 27 or the like.

  In addition, even if one of the locks 90a, 90b and the vacuum pump fails, the lock can be performed if the other is normal, so that a refrigerator having a highly reliable oxygen reduction function can be provided.

Third embodiment

  The refrigerator of the third embodiment is different from the above-described embodiment in that only a specific user can unlock the refrigerator. Specifically, the user is allowed to input a password to turn on the lock release button 201, and only the person who knows the password can release the lock.

  In addition, the refrigerator main body 12 is provided with a camera that captures the outside of the refrigerator in place of the password, and the user who tries to operate the unlock button 201 is discriminated by the image recognition function of the camera. Control may be performed so that the lock release button 201 can be effectively operated only when it is determined that there is.

  Also, it is set so that the lock cannot be released unless the lock release button 201 is pressed for a predetermined time (for example, 3 seconds) instead of the password, or the lock cannot be released unless the lock release button 201 is continuously pressed a plurality of times. By setting, it may be set so that only a person who knows how to operate the lock release button 201 can release the lock.

  As a result, only a specific user who can effectively operate the unlock button 201 can release the lock, so that the lock is not released by an unintended user's hand, and the oxygen reduction state is stable. Can be maintained.

Fourth embodiment

  The refrigerator of the fourth embodiment is different from the above-described embodiment in that the lock of the CA storage room 27 can be controlled from a remote place. As shown in FIG. 10, the refrigerator according to the present embodiment is communicably connected to an external communication line 102 via a router 101. The router 101 is a so-called wireless access point, and is connected so as to be communicable with the refrigerator 10 by a wireless communication method. The refrigerator 10 exchanges various information between the communication terminal 103 and the server 104 connected to the communication line 102. In the present embodiment, a so-called smartphone (high-function mobile phone) that can be carried outside the house 105, a tablet personal computer, or the like is assumed as the communication terminal 103.

  Information regarding the operation of the locks 90a and 90b of the refrigerator 10 is confirmed by the communication terminal 103, and it is determined whether the lock is in an effective state or an invalid state at the current time. Thereafter, when it is desired to change the lock state, command information is input to the communication terminal 103 to change the lock state. When the lock state is changed, the communication terminal 103 is notified that the lock state has been changed, and the lock state can be confirmed by the communication terminal 103 serving as a lock notification unit. In addition to the case where the lock is changed by the operation of the communication terminal 103, notification that the lock state has been changed is performed. For example, even when the user changes the lock state by operating the lock button 202 and the lock release button 201 of the operation display unit 200 of the refrigerator 10, the communication terminal 103 is notified that the lock state has been changed.

  As a result, the lock state can be confirmed and changed from a remote location by the communication terminal 103, so that it is possible to prevent the CA storage room 27 from being opened unintentionally by another user and even if it is opened. If it is good, the lock can be released even from a remote location so that it can be opened.

  Further, when the lock is changed, the information on the change can be confirmed by the communication terminal 103, so that the latest lock state can be confirmed every time the lock state is changed.

  According to at least one embodiment described above, the following operational effects can be obtained.

  Since the control unit 13a provided in the refrigerator 10 can control the locks 90a and 90b to switch the lock and release of the lid 27b, the lid 27b is set in a locked state so that the user can open the lid 27b. This can prevent the user from unnecessarily opening the cover 27b of the CA storage chamber 27 and maintain the reduced oxygen state in the CA storage chamber 27 for a long time.

  The above embodiment is an illustration and the scope of the invention is not limited to this. The above embodiments can be implemented in various other forms, and various omissions, substitutions, and changes can be made without departing from the scope of the invention.
