Description

Storage {STORAGE}

The present invention relates to a storage room.

As a storage method for maintaining the leadingness of foods, CA (Controlled Atmosphere) storage for regulating the composition and pressure of air in the reservoir is known. As the CA storage method, there is a gas replacement method in which air in the storage is replaced with a gas such as nitrogen or carbon dioxide, a vacuum method in which a vacuum pump is used to depressurize the inside of the storage, and a polymer electrolyte membrane And an adsorption system that adsorbs oxygen to the oxygen adsorbent placed in the reservoir by the chemical reaction in the reservoir. By any means, it is possible to reduce the amount of oxygen that oxidizes the food and lowers its lead from within the reservoir, and keeps the food under the oxygen-reduced condition. It is known that CA storage is particularly effective in maintaining the leading of vegetables. In the case of carrying out the CA storage, it is necessary to shut off the circulation of air in and out of the storage compartment in order to keep the specific storage compartment in the storage compartment in the oxygen reduction state.

The pair of left and right support frames 28a are slidably supported in the forward and backward directions by the fixed rails 28b provided on the right and left side walls of the vegetable compartment 24 and are pushed rearward to a predetermined position, Be compelled.

A box-shaped vegetable container 26 having an upper surface opened is supported on a pair of left and right support frames 28a. As a result, the vegetable container 26 is slidably supported in the forward and backward directions by the support frame 28a and the fixed rail 28b constituting the slide rail 28, The vegetable container 26 is taken out to the outside, and the vegetable container 26 is housed in the cabinet together with the closing operation of the vegetable room door 25. [ A door switch 25a is provided at a position opposed to the vegetable compartment door 25 of the refrigerator main body 12 so as to detect whether the vegetable compartment door 25 is in an open state or in 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 number of times the vegetable compartment door 25 is opened by the control unit 13a is calculated.

A CA (Controlled Atmosphere) storage chamber 27 is provided above the vegetable container 26 in a state of being suspended from the partition body 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 inner food container 29 housed in the main body 27a .

The shape of the main body 27a is a flat rectangular parallelepiped which is longer in the width direction and the depth direction than the height direction. It is preferable that the main body 27a is integrally formed with the lower surface of the partition body 21 and fixedly attached within the vegetable compartment 24, but it may not be integrally formed. An annular groove 29e is provided in the peripheral edge portion 29c of the front opening 27c so as to surround the opening (see FIG. 8), and an annular sealing packing 29d is fitted in the groove 29e.

The inner food container 29 has a box-like shape whose upper surface is opened, and food can be taken in and out of the opening. The inner food container 29 is provided with a lid 27b detachably provided in front of the inner food container 29 and can slide back and forth in the CA storage chamber 27 with the lid 27b mounted thereon. A recess 29b-1 is formed at the center of the front face of the lid 27b as shown in Fig. 7 and a handle 29b-2 is provided so as to cover about half an upper portion of the recess 29b-1 have.

As shown in Figs. 7 and 8, locks 90a and 90b are provided on the upper side and the lower side of the front opening 27c at the upper and lower portions of the front opening 27c of the main body 27a And is rotatably provided around the shafts 91a and 91b. The locks 90a and 90b have projections 92a and 92b having a tapered shape whose cross-sectional shape is tapered 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 and brought into contact with the front opening 27c of the main body 27a, the lid 27b is closed by the seal packing 29d ). In this state, the upper lock 90a is rotated downward and the lower lock 90b is rotated upward, and the projections 92a and 92b are engaged with the cover 27b. At this time, since the projections 92a and 92b have a tapered shape in which the cross-sectional shape of the projections 92a and 92b is tapered toward the tip, the projections 92a and 92b are engaged with the entire surface of the lid 27b without extreme deformation of the projections 92a and 92b . The cover 27b is pressed by the protrusion 92 to the peripheral edge portion 29c of the front opening 27c and fixed to the front opening 27c of the main body 27a to be locked. The locks 90a and 90b are automatically rotated by driving a motor (not shown) which receives a command from the controller 13a to lock and release the locks.

7, the lower end of the lid 27b is supported by the upper end 26a of the right and left side walls of the vegetable container 26. As shown in Fig. Thus, the lid 27b can slide in the front-rear direction over the upper end 26a of the sidewall of the drawn-out vegetable container 26 first. The inner food container 29 mounted on the cover 27b is supported by the vegetable container 26 through the cover 27b and can slide along the vegetable container 26 with the cover 27b in the forward and backward directions . It is also possible to provide a mechanism for reducing the friction of the roller or the like on one side of the lower end of the lid 27b or on the side wall upper end 26a of the vegetable container 26. When the lid 27b is moved smoothly above the upper end 26a To move back and forth.

When the internal food container 29 is taken out from the CA storage chamber 27, the vegetable chamber door 25 is first opened. At this time, the vegetable container 26 is taken out to the outside together with the door opening operation of the vegetable room door 25 as described above. However, the closed state of the CA storage chamber 27 and the door opening are not interlocked with the opening of the door of the vegetable room door 25 or the withdrawal of the vegetable container 26, Even when the door is opened, its front opening 27c is closed by the lid 27b (see Fig. 4). When the locks 90a and 90b are released from this state and the handle 29b-2 of the lid 27b is pulled forward, the sealing of the CA storage chamber 27 is released and the inner food container 29 are supported by the vegetable container 26 and come forward (see Fig. 3). When the inner food container 29 is pulled out to the end, it can be taken out from the CA storage chamber 27 and taken out. Conversely, when the inner food container 29 is housed in the CA storage chamber 27, the inner food container 29 is pushed into the CA storage chamber 27 and the lid 27b Is brought into contact with the seal packing 29d so that the front opening 27c of the main body 27a is blocked by the lid 27b and locked by the locks 90a and 90b. In this way, the inflow of the ambient air into the CA storage chamber 27 is blocked, and the sealed state is established (see Fig. 8).

On the other hand, as shown in Fig. 5, an opening portion 27d opened rearward and a rib 35 protruding into the CA storage chamber 27 are provided on the back surface of the CA storage chamber 27. As shown in Fig.

The opening portion 27d includes a plurality of through holes 27d-1 penetrating the back surface of the CA storage chamber 27. For example, a slit-shaped through hole 27d-1 extending in the up- As shown in FIG. The through hole 27d-1 constituting the opening 27d may be a circular hole or a square hole as well as a slit shape.

The ribs 35 protruding from the back surface of the CA storage chamber 27 can be formed as projecting ribs provided on both right and left sides of the opening 27d and extending in the vertical direction from the bottom surface of the CA storage chamber 27, The shape seen from the front side of the opening 35d is not particularly limited. For example, the rib 35 may be provided so as to surround the opening 27d.

An ice making chamber (not shown) having an automatic ice maker and a first freezing chamber 44 are juxtaposed on the left and right in a freezing space 40 provided below the vegetable compartment 24 through a heat insulating partition wall 14, And a second freezing chamber 46 is provided at the lower part thereof.

The openings of the ice making chamber, the first freezing chamber 44 and the second freezing chamber 46 are also closed by the pull-out doors 45 and 47 like the vegetable room 24, A pair of left and right support frames fixedly attached to the support frame hold the storage containers, and the storage containers are pulled out to the outside together with the door opening operation.

On the rear surface of the refrigerating space 20 is provided a refrigeration cooler 52 and a refrigeration fan 53 for cooling the air in the refrigeration space 20 and the air cooled by the refrigeration cooler 52 is introduced into the duct And is blown into the refrigerating compartment 22 through the refrigerating compartment 37 to cool the refrigerating compartment 22. The air that has flown through the refrigerating compartment 22 flows into the vegetable compartment 24 through a through hole (not shown) provided in the partition body 21 to cool the inside of the vegetable compartment 24, (31) and returns to the refrigerator cooler (52).

2, a water receiving portion 56 for receiving water generated by the defrosting of the cooling cooler 52 is provided below the cooling cooler 52, and the water receiving portion 56 is provided below the water receiving portion 56 And an oxygen abatement device 60 are provided. The water receiver 56 and the oxygen abatement device 60 are connected by a hose 57 and the distillate water received in the water reception 56 is supplied to the oxygen abatement device 60 through the hose 57.

The refrigerator further comprises a freezing cooler 54 for cooling the air in the freezing space 40 and a second freezing chamber 44 for cooling the air cooled in the freezing cooler 54 to the ice making chamber, And a cooling fan 55 for blowing air to the cooling fan.

The refrigeration cooler 52 and the freezing cooler 54 constitute a refrigeration cycle for both the compressor 32 provided at the lower part of the rear surface of the refrigerator main body 12 and the condenser and the switching valve not shown, And is cooled by the refrigerant and the inside of each storage room provided in the refrigeration space 20 and the freezing space 40 is cooled to a predetermined temperature by controlling the refrigeration fan 53 and the refrigeration fan 55. [

The oxygen abatement device 60 is accommodated in the case 64 in a state in which the plate-like solid polymer electrolyte membrane 61 is sandwiched by the anode electrode 62 and the cathode electrode 63, It is. When a voltage is applied between the anode electrode 62 and the cathode electrode 63, defrost water supplied from the water receiving portion 56 to the oxygen reduction device 60 through the hose 57 or water in the air is supplied to the anode electrode 62 Hydrogen ions generated by decomposition move from the anode electrode 62 side to the cathode electrode 63 side. The oxygen in the CA storage chamber 27 is reduced by generating water by reacting with oxygen in the CA storage chamber 27 through the opening portion 27d of the CA storage chamber 27 from the opening 65 provided in the case 64 .

The oxygen abatement device 60 is installed in the return duct 31 so that the cathode 63 is opposed to the opening 27d of the CA storage chamber 27 through the opening 65 provided in the case 64. [

The oxygen abatement device 60 operates by avoiding a time zone in which the door opening number of the vegetable room door 25 having the CA storage room 27 is large. That is, when the door opening of the vegetable room door 25 is detected more than the predetermined number of times by the door switch 25a provided in the vegetable room door 25 in the preset time zone, for example, 25 are opened, it is determined that the number of opening times of the vegetable room door 25 is large. The cover 27b is unlocked by the locks 90a and 90b and the user can freely open the CA storage chamber 27 without operating the oxygen abatement device 60 at a time when the number of times of opening of the door is large. State. The operation of the oxygen reduction apparatus 60 is started after a predetermined time (for example, one hour) in the time zone in which the door opening frequency is large. In addition, since the oxygen abatement apparatus 60 starts operation before the predetermined time (for example, 30 minutes) for starting the operation of the oxygen abatement apparatus 60, the CA storage chamber 27 can be opened for a while (Not shown) is displayed on the operation display section 200 (see FIG. 9). After the oxygen reduction apparatus 60 actually starts operating, the fact that the oxygen reduction apparatus 60 is in the operating state is displayed on the operation display section 200 Display.

On the other hand, when the door switch 25a detects that the opening of the door of the vegetable room door 25 is less than the predetermined number of times in the preset time zone, it is determined that the number of door opening times of the vegetable room door 25 is small, The lid 27b is locked by the openings 90a and 90b and the operation of the oxygen abatement apparatus 60 is started.

It is also possible to lock the CA storage chamber 27 by the locks 90a and 90b substantially simultaneously with the start of operation of the oxygen reduction apparatus 60 so that the user can not open the CA storage chamber 27, Is displayed on the operation display unit 200 having the function as the lock notifying means.

The locks 90a and 90b remain locked until the predetermined period of time (for example, four hours) has elapsed after the oxygen reduction apparatus 60 has started its operation. After the lapse of a predetermined time, the locks 90a and 90b are automatically released so that the user can freely open the CA storage chamber 27 and store it in the CA storage chamber 27 in the operation display unit 200 Indicating that a stored product is maintained in an oxygen-reduced state.

When the user wants to open the CA storage room 27 in a locked state, the lock release button 201 provided on the operation display unit 200 is turned on to release the lock. On the other hand, when the lock is erroneously released, or when it is desired to release the lock after the lock is released automatically, the lock can be made effective by turning on the lock button 202. It is preferable that the unlocking button 201 provided on the operation display unit 200 is provided at a position such that the upper portion of the refrigerator 10 does not reach the hands of infants.

Thereby, when the user intends to open the CA storage chamber 27, the user can easily open the CA storage chamber 27 when the amount of oxygen in the CA storage chamber 27 is small, Can be prevented.

Since the oxygen releasing device normally completes the operation and the predetermined time has elapsed, the lock is automatically released after the storage in the oxygen reduction state is completed. Therefore, the user does not need to release the lock when the lock is unnecessary, good.

The lid 27b of the CA storage chamber 27 is suppressed to the main body 27a by the locking so that the airtightness is improved and the rise of the oxygen concentration due to the inflow of air from the outside of the CA storage chamber 27 can be prevented more reliably can do.

Since the user operates the oxygen abatement device 60 to take out the stored product in the CA storage compartment 27 or to operate the oxygen storage device 27 in the CA storage compartment 27 because the opening of the vegetable compartment 24, It is possible to prevent the situation in which the oxygen abatement apparatus 60 is operating and can not be taken out or stored.

Since the oxygen abatement apparatus 60 predicts the operation of the oxygen abatement apparatus 60 a predetermined time before the oxygen abatement apparatus 60 starts operation, when the oxygen abatement apparatus 60 is operated So that it is possible to prevent a situation in which it can not be locked and taken out or stored.

It is possible to easily determine whether or not the oxygen abatement device 60 is operating and whether the locks 90a and 90b are functioning by confirming the operation display unit 200 by the user, 27 can be prevented from being opened.

It is possible to prevent the infant from releasing the lock by jamming or the like and opening the CA storage chamber 27 by disposing the unlocking button 201 at a height not reaching the infant's hand.

The opening of the door of the vegetable compartment 24 and the opening of the lid 27b of the CA storage compartment 27 are carried out independently and the sealing of the CA storage compartment 27 is not opened even when the vegetable compartment 24 is opened. Therefore, even if the vegetable compartment door 25 is frequently opened for entering and exiting the food in the vegetable container 26 of the vegetable compartment 24, the amount of oxygen in the CA storage compartment 27 can be kept low. Therefore, it is not necessary to operate the oxygen abatement apparatus 60 every time the vegetable compartment 24 is opened, and the power consumption can be suppressed.

Since the CA storage chamber 27 is provided above the vegetable container 26 in the vegetable compartment 24, a space that is difficult to use in the vegetable compartment 24 can be effectively utilized. Even if the CA storage chamber 27 is disposed above the vegetable container 26 because the inner food container 29 with the top opened is provided in the CA storage chamber 27, It is easy to take out food, and does not impair convenience of use. In addition, by providing the CA storage chamber 27 integrally with the partition body 21, it is possible to standardize components and further utilize the interior of the vegetable chamber 24 more effectively.

Since the CA storage chamber 27 is provided in the vegetable chamber 24, it can be mainly used for storage of vegetables having a high effect of CA storage. Also, since the inside of the vegetable compartment 24 is relatively high in the refrigerated space 20, foods that tend to cause low temperature obstructions such as branches and bananas can be preserved in an oxygen-reduced state without deteriorating the quality.

The CA storage chamber 27 is integrally provided with the partition body 21 so that the CA storage chamber 27 to which the oxygen abatement device 60 is fixedly attached can not be drawn out, It is possible to prevent contact and breakage. Since the inner food container 29 can be taken out from the CA storage chamber 27, the inner food container 29 can be taken out and cleaned.

Since the CA storage chamber 27 is configured to be hermetically sealed at its front surface, in the case of the CA storage chamber 27, which is a flat rectangular parallelepiped having a width direction and a longitudinal direction longer than the height direction, It is possible to reduce the possibility that the sealing is inhibited.

In the first embodiment described above, a case where the lid 27b is fixed to the main body 27a with the locks 90a and 90b is used as a lock mechanism for preventing the opening of the lid 27b of the CA storage chamber 27 The display for prohibiting the opening of the lids 27b is displayed on the operation display unit 200 to interrupt the opening of the lid 27b or to output a voice for prohibiting the opening of the lid 27b by using a speaker The cover 27b may be prevented from opening.

In the above-described first embodiment, the case where the CA storage room 27 is always displayed on the operation display unit 200 is described as an example. However, in the case of the vegetable room 24 having the CA storage room 27, It may be displayed whether or not the door 25 is locked only when it is opened. Alternatively, a speaker may be provided in the storage room, and it may be configured such that it is notified that it is locked by voice using a speaker as a lock notification means instead of being displayed on the operation display section 200. According to this, when the vegetable compartment door 25 of the vegetable compartment 24 as the storage compartment having the CA storage compartment 27 is closed and the CA storage compartment 27 is not opened, the locked state is not notified, .

[Second Embodiment]

The storage of the second embodiment differs from that of the first embodiment in that locking is performed by depressurizing the CA storage chamber 27 instead of locking the locks 90a and 90b.

In the second embodiment, a vacuum pump for changing the pressure in the CA storage chamber 27 is provided. When it is desired to perform locking, the air in the CA storage chamber 27 is sucked by a vacuum pump to decompress. As a result, the CA storage chamber 27 is locked to receive the pressure from the outside to the inside due to the pressure difference generated inside and outside the CA storage chamber 27. On the other hand, when it is desired to release the lock, the air in the CA storage chamber 27 is sent by the vacuum pump to pressurize the pressure in the CA storage chamber 27 so as to suppress the influence of the pressure and make the valve openable.

Thus, in the same manner as in the first embodiment, when the user intends to open the CA storage chamber 27, the lock by the pressure difference can be released and released. Thus, when the amount of oxygen in the CA storage chamber 27 is small, It is possible to prevent the CA storage chamber 27 from being opened easily.

In addition, in order to simultaneously perform the depressurization operation by the vacuum pump in the operation state of the oxygen reduction apparatus 60, the oxygen amount in the CA storage chamber is faster than that in the case where only the oxygen reduction apparatus 60 is operated, So that it is possible to more effectively obtain the leading keeping effect of the stored product due to the oxygen reduction.

In the second embodiment, a vacuum pump is provided instead of the locks 90a and 90b. However, a vacuum pump may be provided in addition to the locks 90a and 90b to lock the locks 90a and 90b.

As a result, the airtightness of the oxygen reduction chamber 27 can be further improved, and hence the oxygen reduction concentration can be prevented from rising due to the inflow of air into the oxygen reduction chamber 27 or the like.

Further, even when one of the locks 90a, 90b and the vacuum pump is broken, the lock can be performed if the other is normal, so that it is possible to provide a refrigerator having a highly reliable oxygen reduction function.

[Third embodiment]

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

Further, it is also possible to provide a camera for photographing the outside of the refrigerator in the refrigerator body 12 instead of the password, and a user who wants to operate the unlocking button 201 is determined by the image recognition function by the camera, The lock release button 201 may be controlled so as to be operable effectively.

Alternatively, if the lock release button 201 is not depressed continuously for a predetermined time (for example, 3 seconds), the lock can not be released, or if the lock release button 201 is not pressed a plurality of times in succession, So that only the 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 lock release button 201 can release the lock, so that the lock can not be released by an unintended user's hand and the oxygen reduction state can be stably maintained.

[Fourth Embodiment]

The refrigerator of the fourth embodiment is different from the above-described embodiment in that the lock of the CA storage chamber 27 can be controlled remotely. 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. Fig. The router 101 is a so-called wireless access point and is connected to the refrigerator 10 in a wireless communication manner. The refrigerator 10 exchanges various information between the communication terminal 103 and the server 104 which are connected to the communication line 102. In the present embodiment, a so-called smart phone (high-performance mobile phone), a tablet-type personal computer, or the like, which is portable outside the home 105, 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 valid or invalid at the present time. Thereafter, when it is desired to change the state of the lock, the command information is input to the communication terminal 103 and the state of the lock is changed. When the state of the lock is changed, the communication terminal 103 is notified that the state of the lock has been changed, and the state of the lock can be confirmed by the communication terminal 103 as the lock notification means. In addition to the case where the lock is changed by the operation of the communication terminal 103, notification is made that the state of the lock has been changed. Even if the user changes the state of the lock by operating the lock button 202 and the lock release button 201 of the operation display unit 200 of the refrigerator 10, Notification of the change is notified.

Thereby, the state of the lock can be confirmed and changed from a remote place by the communication terminal 103, so that it is possible to prevent the CA storage room 27 from being opened without intention by another user, It is possible to release the lock from a remote place and make it openable.

In addition, when the lock is changed, information of the change can be confirmed by the communication terminal 103, so that the state of the latest lock can be confirmed each time a change occurs in the lock state.

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

The control unit 13a provided in the refrigerator 10 can control the locks 90a and 90b to switch the locking and unlocking of the lid 27b so that the lid 27b is set in the locked state, 27b of the CA storage chamber 27 can be prevented and the user is urged not to open the lid 27b of the CA storage chamber 27 and can maintain the oxygen reduction state in the CA storage chamber 27 for a long time.

The embodiment described above is an example, and the scope of the invention is not limited thereto. The above-described embodiments can be implemented in various other forms, and various omissions, substitutions, and alterations can be made without departing from the gist of the invention. The above embodiments and modifications are within the scope of the invention described in claims and equivalents thereof.
