Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator, and more particularly, to a cooling system in which cold air is circulated by forced air to cool the inside of the refrigerator, and at least one of the plurality of storage chambers has a door. The present invention relates to a refrigerator that is a drawer-type storage room equipped with a storage container.

[0002]

2. Description of the Related Art The structure of a general household refrigerator is, in terms of function, a box body and a door portion which are main bodies having a role of a heat insulating container and a strength member, and a refrigeration cycle for cooling the inside of the refrigerator. It can be roughly divided into parts. The box and door parts are made by sandwiching the outer box and outer plate made of steel plate and the inner box and inner plate made of resin, mainly by sandwiching the heat insulating material made of urethane foam. Partition members that largely divide storage compartments such as frozen storage compartments, refrigerated storage compartments, and vegetable storage compartments and cold air passages under different conditions, and shelves that partition storage compartments and the inside of doors into smaller compartments, storage containers and pockets made of resin. Alternatively, it is composed of an interior component made of a heat insulating material. The refrigeration cycle part is a component installed outside the refrigerator such as a compressor for boosting and circulating the refrigerant and a condenser for heat dissipation, and an evaporator for cooling the cold air circulating in the refrigerator. Parts such as a blower that circulates cold air and a cooler are installed in the refrigerator, and a refrigerant pipe that connects the parts to circulate a refrigerant.

In a general refrigerator having a plurality of storage rooms,
Cooling in the refrigerator is performed by a cold air forced circulation system in which cold air cooled by an evaporator is circulated to each storage chamber by a blower and a cold air passage. Then, the heat in the refrigerator taken by the evaporator is carried to the condenser outside the refrigerator by the refrigerant circulating in the refrigeration cycle and released.

In the structure of the storage room of the refrigerator, the door is opened and closed by pivoting about a hinge fixed to one side surface of the box, and stored items are stored in shelves inside the box or pockets inside the door. There are a fixed shelf type and a drawer type in which the door is opened / closed by the same rotation or sliding in the front-back direction with respect to the box body, and the storage container is slid in / out from the box body in the front-back direction. Generally, in the drawer type storage chamber, when the storage chamber corresponding to one door is relatively small and the number of storage containers in the room is two or less, the door and the storage container slide together. In particular, in the case where the storage container has two stages in the vertical direction, the storage container in the upper stage has a structure that can be independently slid with the door opened and pulled out. On the other hand, when the storage chamber is large and three or more storage containers are accommodated in the storage chamber,
One door is rotated with respect to the storage chamber, and each storage container can slide independently without opening and closing the door.

Such a drawer-type storage chamber is often used as a storage chamber in the lower half of the refrigerator from the viewpoint of easy removal of stored items. Also, recent refrigerators
With a focus on ease of use of the cold storage room, the upper half of the refrigerator has only one fixed shelf cold storage room, and the lower half has a plurality of drawer-type freezing storage rooms, vegetable storage rooms, etc. Has been widely adopted, and the number of drawer-type storage rooms is increasing.

[0006] However, since such a drawer type storage room is located in the lower half of the refrigerator, the door is slightly closed due to catching of stored items in the refrigerator or foreign matter being caught in the packing of the door. It is easy to be left in the open state. Further, when the door is opened in a normal use state, cold air is often drawn out of the refrigerator together with the storage container, or cold air often leaks from a gap existing between the storage container and the inner wall and the partition member. These causes the following problems in using the refrigerator.

Here, the structure around the drawer type storage room in the conventional refrigerator and the situation and problems of cold air circulation will be specifically described with reference to the drawings. 14 and 15 are a vertical side view of a lower half portion of a refrigerator main body in a state where all the doors are closed in a conventional refrigerator and a front view in which the doors of the lower half portion of the refrigerator main body in the same state are omitted. FIG. 16 is a vertical cross-sectional side view of the lower half of the refrigerator main body in a state where a part of the door of the same conventional refrigerator is slightly opened.

In FIG. 14, the refrigerator body 1 basically comprises a box body 2 and a plurality of doors 3a to 3c, an upper half portion is a fixed shelf type refrigerating and storing room 4, and a lower half portion is a plurality of drawers. First and second frozen storage chambers 5a, 5b as storage chambers of the formula
The vegetable storage chambers 6 are arranged in order from the top, and the outer space on the back side and the lower portion of the vegetable storage chambers 6 is a machine room 7. Each of the drawer type storage rooms is mainly composed of partition members 8a, 8
It is divided by b and 8c, and a packing 9 is provided inside each of the doors 3a to 3c for sealing the front flange portion of the box body 2.
a-9c are provided, each door 3a-3c and each storage container 10 are provided.
The a and 10c are moved in and out in such a manner that the guide rails 11a to 11c on the side surfaces of the container slide integrally in the front-rear direction of the box body 2.

The storage containers 10a to 10c are generally open at the upper opening, but in a storage room such as the vegetable storage room 6 which needs to be kept at high humidity, it is disclosed in JP-A-63-116079.
As shown in Japanese Patent Publication No. JP-A-2003-320, a lid 12 facing the upper opening of the storage container 10c is provided so as to stay in the storage, and when the door 3c is closed, the lid 12 opens the storage container 10c. Is to be sealed.

An evaporator 13 and a blower 14 are arranged in the interior of the freezing storage chambers 5a and 5b substantially on the back side, and a cool air 15 is supplied to the supply passage 16 and the return passage formed by the box 2 and the partition members 8a to 8c. It is circulated to each storage chamber 5a, 5b, 6 via 17. The heat taken by the evaporator 13 is released to the outside of the refrigerator via the refrigerant circulating in the refrigeration cycle by the compressor 18 and the condenser 19 arranged in the machine room 7.

As shown in FIGS. 14 and 15, when the refrigeration cycle is operated with all the storage chambers 5a, 5b and 6 having the doors 3a to 3c completely closed, the cool air 15
In the case of the storage containers 10a and 10b whose upper surfaces are opened like the freezing storage chambers 5a and 5b, the storage container 10a is supplied from the upper rear surface by the supply passage 16 and then the storage container 10a is supplied. , 10b overflows around the top opening, and the return passage 1 mainly from the bottom and back of the storage chamber
It returns to the evaporator 13 through 7. Further, in the storage room including the lid 12 that covers the upper opening of the storage container 10c like the vegetable storage room 6, the cool air 15 is stored mainly from the upper rear surface.
It is supplied along the outer periphery of the storage container 10c, and after cooling the outer surface of the storage container 10c, circulates in the form of returning from the side surface of the partition member 8c that partitions the storage chamber or the back surface of the box 2. In particular, in the general vegetable storage compartment 6 arranged at the bottom of the box body 2, most of the cool air 15 is supplied from the upper part of the rear surface to the bottom surface and the side surface of the storage container 10c, and the cold air 15 of the door 3c and the storage container 10c. The lid body 12 is inserted into the return passage 17 inside the storage container 10c and the partition member 8c located above the lid body 12 so as to rise through the vertical front cold air passage 20 formed therebetween.
It merges with the cold air 15 that has passed through the upper surface and returns.

When the temperature inside the refrigerator is below the set value and the refrigeration cycle does not operate, the blower 14 and the compressor 18 are stopped, and the circulation of the cool air 15 as described above does not occur.

However, as shown in FIG. 16, one of the drawer-type storage chamber doors (for example, the doors 3a, 3a) is erroneously formed.
If c) is left in a state in which it is slightly opened up to the thickness of the packings 9a and 9c, the door switch (not shown) cannot detect this open state, and the refrigerator has the door 3
The operation is performed in the same manner as when the a and 3c are completely closed.
In this case, even if the refrigeration cycle is in a stopped state until then, all storage chambers 5a, 5a, 5a
In b and 6, the temperature inside the refrigerator becomes equal to or higher than the set value and immediately becomes the continuous operation state, and the cooling by the evaporator 13 and the circulation of the cool air 15 cause excessive frost formation in the evaporator 13 and start the defrosting operation. I can continue. Even if the opening amount of the doors 3a and 3c is small, since there is a density difference between the cool air 15 and the outside air 21, the cold air 15 leaks out of the refrigerator through the lower gap, and the outside air 21 leaks through the upper gap. A flow in the form of entering the inside is likely to be formed, and the amount of leak of the cool air 15 is likely to increase. In particular, when the door 3c of the vegetable storage compartment 6 is opened, the cold air 15 has a smaller ventilation resistance when leaking through the gap than when the front cold air passage 20 rises. The cold air 15 that has passed through the bottom surface and the side surfaces of the cold air leaks out of the refrigerator almost as it is.

As described above, when the door of the drawer type storage chamber is slightly opened and the refrigeration cycle is continuously operated while a large amount of cold air 15 leaks out, the cold air 15 has high temperature and high humidity. Since the outside air is mixed in and circulates in the refrigerator, damage to stored items due to the rise in the temperature in all the storage chambers 5a, 5b, 6 and continuous operation of the refrigeration cycle and the evaporator
There is a problem that a large increase in the power consumption of the entire refrigerator due to excessive frost formation on 3 appears.

Further, in a normal use state, when the doors 3a to 3c of any of the pull-out type storage chambers 5a, 5b and 6 are opened and the storage containers 10a to 10c are pulled out, the open state is detected by the door switch. The blower 14 is controlled to stop regardless of whether the refrigeration cycle is operating or is stopped by the door 3a (3b, 3c).
The cold air 15 is prevented from leaking from the storage chambers other than the opened storage chamber 5a (5b, 6). However, the storage container 10a (10b, 10c) and the surrounding box 2
Since a relatively large gap required for sliding the storage container 10a (10b, 10c) is formed between the inner wall of the storage container and the side surfaces of the partition members 8a to 8c, the storage container 10a (10b, 10b, 10c). Even when most of the cool air 15 in the storage chamber 5a (5b, 6) leaks out by pulling out the storage container 10c), the outside air 21 that has flowed into the storage chamber from above is cooled in the state in which the storage container is pulled out. The inflow of the outside air 21 continuously occurs as it flows out from the lower part.

In this way, the drawer type storage chamber 5a (5
Open the door 3a (3b, 3c) of b, 6) and the storage container 10
In the state where a (10b, 10c) is pulled out, the initial temperature of the cold air 15 leaks out and the outside air 21 continuously intrudes, which causes the internal temperature to rise, so that the door 3a (3
b, 3c) to damage the stored products in the storage chamber 5a (5b, 6) or to recool the storage chamber 10a (10b, 10c) after closing the door 3a (3b, 3c) This causes a problem that the power consumption of the entire refrigerator increases.

In the normal use condition, the storage chambers 5a, 5a
When any one of the doors 3a to 3c of b and 6 is opened, if this opening time is long, the influence of the blower 14 being stopped due to the opening detection by the door switch also appears in the storage room with the door closed ( Not limited to pull-out type). As shown in Fig. 16, as can be seen in recent general refrigerators,
A drawer-type vegetable storage room 6 has an evaporator 1 at the bottom of the box 2.
In the structure in which 3 is arranged immediately above, the blower 14 is stopped by opening the door 3a (3b) of the storage room 5a (5b) different from the vegetable storage room 6, and the door 3a ( Three
Supposing that the refrigeration cycle is operating or the refrigeration cycle was originally operating due to the rise in the internal temperature of the storage chamber 5a (5b) with the b) opened, the compressor 18 operates and the evaporator 13 rapidly operates. When the temperature becomes extremely low, the cool air 15 having a considerably low temperature flows from the evaporator 13 into the vegetable storage chamber 6 due to the difference in density and flows backward through the return passage 17. As a result, a part or all of the vegetable storage compartment 6 becomes below the freezing point, causing a problem that the stored vegetables freeze and are damaged. Regarding this problem, Japanese Patent Laid-Open No. 5-223431 discloses a measure for preventing the freezing of vegetables by changing the control of the blower 14, but there are accompanying problems other than the freezing prevention, for example, an increase in power consumption as described below. There are not enough countermeasures taken against them. Even if the storage room whose door is not opened is not the vegetable storage room 6 as described above, if the blower 14 is stopped and the refrigeration cycle is in operation due to the door of the other storage room being opened, that storage room is moved to that storage room. Since the circulation of the cold air 15 is interrupted, there is a problem that the temperature inside the refrigerator rises due to heat intrusion from the heat insulating wall of the refrigerator body 1 and the stored products are damaged. Further, since the blower 14 is stopped while the compressor 18 is operating, an irregular operating state occurs, which causes a problem that the power consumption of the entire refrigerator increases as compared with the normal intermittent operation.

As an example of countermeasures against the problem of leakage of cold air when the door of the storage chamber is opened in this way, a fixed shelf type storage chamber is disclosed in JP-A-6-180179 and JP-A-6-180180. There is known a measure for providing a sealing member inside the refrigerator rather than the packing of the door as shown in Japanese Patent Publication No. These are measures for the fixed shelf type storage room, and the effect is exhibited only when the door is slightly opened. In addition, regarding the drawer-type storage chamber, there is an example where measures were taken to provide a seal member at a part of the lower part of the inside of the door, but this also exhibits its effect only when the door is slightly opened. It is a thing.

DISCLOSURE OF THE INVENTION The present invention is a problem in the conventional refrigerator having the drawer type storage chamber as described above, that is, when the door is left open with a slight opening or in a normal refrigerator. Other drawers that do not open due to cold air leaking in the storage room that occurs when the door is opened and the storage container is pulled out in use, and temperature rises due to ingress of outside air, or the doors of other storage rooms have been opened An object of the present invention is to solve the problems of damage to stored items in the drawer type storage chamber and increase in power consumption of the entire refrigerator due to temperature fluctuations occurring in the storage type chamber.

[0020]

According to the present invention, cool air generated in an evaporator is circulated to a plurality of storage chambers in a refrigerator body by a blower through a supply passage and a return passage, and at least one of the storage chambers is circulated. Is a drawer-type storage chamber provided with a door and a storage container, and the door of the drawer-type storage chamber is pivoted about a hinge fixed to one side of a front flange of the refrigerator body or the refrigerator body. In the refrigerator in which the storage container is opened and closed by sliding in the front-rear direction with respect to the refrigerator body, and the storage container is moved in and out by sliding in the front-rear direction with respect to the refrigerator main body, the first feature is, regarding the drawer-type storage chamber, the door and the storage. A front cold air passage extending vertically between the containers is formed with the door substantially closed, and a gap around the front surface of the storage container and the front cold air passage is formed. A soft, fin-shaped seal member for stopping is provided inside the refrigerator near the front flange of the refrigerator body, and the seal member is in a range from a state where the door is fully closed to a state where the door is opened to about the thickness of the packing. The tip of the drawer keeps contact with the surfaces of the members facing each other with a gap in between, and incidentally, the drawer type storage chamber accommodates the storage containers in a plurality of stages in the vertical direction, and the storage in the lower stage. A soft, fin-shaped sealing member is provided on the upper front portion of the container, and the tip of the sealing member is arranged to keep contact with the surface of the upper storage container that faces the storage container with a gap therebetween. The magnetic force assists the contact between the tip of the sealing member and the surface of the opposing member in the range from the fully closed state to the state where the door is opened to the thickness of the packing.

A second feature of the drawer-type storage chamber is that both sides of the storage container except for the front surface of the storage container are exposed to the outside of the storage when the storage container is pulled out to the maximum in normal use. A soft and fin-shaped sealing member that seals the gap between at least both side surfaces and the bottom surface of the storage container in a pulled-out state while forming the outer surface shape of the surface and the bottom surface into a constant cross-sectional shape when viewed from the front. Provided inside the refrigerator near the front flange of the refrigerator main body, so that the tip of the sealing member keeps contact between both side surfaces and the bottom of the storage container near the front surface of the refrigerator main body when the storage container is pulled out. In addition, incidentally, the drawer type storage chamber accommodates storage containers in a plurality of stages in the vertical direction, and a soft and fin-shaped seal member is provided on the upper front surface of the storage container in the lower stage, The seal part The tip of the storage container is kept in contact with the surface of the upper storage container that is opposed to the storage container of the upper stage, and the drawer type storage chamber is a lid that seals the upper surface of the storage container in a form that remains inside the storage chamber. A vegetable storage room provided with, the sealing member for sealing the upper surface of the storage container,
The tip of the sealing member contacts the upper part of the front surface of the lid when the storage container is pulled out.

Furthermore, a third feature is that the passage switching means and the passage blocking means are provided in the supply passage and the return passage of each storage chamber, and the door of any one of the storage chambers is opened and any one of the storages is stored. When it is necessary to circulate the cold air because the temperature inside the chamber is higher than a set value, the blower is not stopped due to the detection of the opening of the door, and the door is opened to the storage chamber. The blast of the cool air is stopped by diverting it directly from the supply passage to the return passage, and the blast of the cool air to the storage chamber in which the door including the pull-out type storage chamber is not opened is the same as the supply passage. There is provided a control device for controlling the blower, the passage switching means, and the passage blocking means so as to continue using the return passage, and the fourth feature is that, with respect to the drawer type storage chamber, A front cold air passage extending vertically between the door and the storage container is formed in a substantially closed state of the door, and the storage container is pulled out to the outside of the refrigerator in a state of being maximized in a normal use state. In the exposed area, the outer surface shapes of both side surfaces except the front surface of the storage container and the bottom surface are made to have a constant cross-sectional shape when viewed from the front, and at least the gap around the both sides and the bottom surface of the storage container is sealed. A soft, fin-shaped seal member for stopping is provided inside the refrigerator near the front flange of the refrigerator main body, and the tip of the seal member makes contact with both side surfaces and the bottom surface of the storage container when the storage container is pulled out. It is to keep near the front of the refrigerator body, and incidentally, a passage switching means and a passage blocking means in the supply passage and the return passage of each storage chamber,
When the door of any of the storage chambers is opened and the internal temperature of any of the storage chambers is higher than the set value, it is necessary to circulate the cold air, and thus the blower is stopped by detecting the opening of the door. To stop the air blowing of the cool air to the storage chamber with the door opened directly by diverting from the supply passage to the return passage,
Further, the blower, the passage switching means and the passage blocking means are arranged so that the cooling air is continuously blown to the storage chamber in which the door is not opened including the drawer type storage chamber using the supply passage and the return passage. There is a control device for controlling.

[0023]

The seal member that seals the gap around the front surface of the front cold air passage formed between the door of the drawer type storage chamber and the storage container is left as it is with the door of the drawer type storage chamber slightly opened. Even in the open state, the leakage of cold air from the drawer-type storage chamber is suppressed to a small extent. If the door is opened slightly, the open switch will not detect the opening, so the refrigeration cycle will operate intermittently as in the case where the door is closed, but the front cold air passage will allow good circulation of cold air in the refrigerator. . Therefore, even if the door of the pull-out type storage room is opened slightly and left alone, there is almost no occurrence of cold air leaking out or outside air entering and the temperature rise inside the freezer, and the refrigeration cycle does not enter into continuous operation. The damage to the stored items in the room and the increase in the power consumption of the entire refrigerator hardly appear.

Further, since the space between the side surface and the bottom surface of the storage container which is pulled out to the outside of the storage and the surrounding space is sealed by the seal member, the door of the pull-out type storage chamber is opened and the storage container is pulled out in a normal use state. The continuous invasion of outside air when pulled out is significantly reduced. Therefore, when the door of the drawer-type storage chamber is opened and the storage container is pulled out, the invasion of outside air is suppressed, the temperature rise in the storage is reduced, and the re-cooling of the storage after closing the door is also reduced. , Damage to stored items in the storage room with the door opened and increase in power consumption of the entire refrigerator are reduced.

Further, when the door of any of the storage chambers is opened and the refrigeration cycle is operated to circulate the cool air, the ventilation is controlled not to stop even if the door switch detects the opening. . And in the storage room where the doors are opened, the blowing of cold air is stopped, and in the storage rooms where the doors are not opened including the drawer type storage room, the ventilation of the cool air is continued and all the doors are closed. Perform almost the same cooling. When the door of any of the storage rooms is opened, temperature fluctuations in storage rooms that do not have doors open, including drawer type, hardly occur, so damage to stored items does not appear, and the refrigeration cycle also operates irregularly. The increase in the power consumption of the refrigerator as a whole does not appear.

[0026]

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a vertical cross-sectional side view of the lower half of the refrigerator main body in the first embodiment of the refrigerator according to the present invention with a part of the door of the refrigerator slightly opened. FIG. 3 is a front view of the same state where the door of the lower half of the refrigerator main body is omitted. The basic structure of the refrigerator and the circulation of cold air with the door closed are almost the same as those of the conventional refrigerator described above, and therefore, the same reference numerals are given to them and duplicate description will be omitted.

In this embodiment, vertical front cold air passages 20a to 20c having upper and lower openings are provided between the doors 3a to 3c of each drawer type storage chamber and the storage containers 10a to 10c. The front-side cold air passages 20a to 20c are formed by adding a passage forming member to the front surface of each of the storage containers 10a to 10c and integrating them, and by arranging the passage forming member in close contact with the inner surfaces of the doors 3a to 3c. To be done. Fin-shaped sealing members 22a to 22i made of a soft material are installed inside the refrigerator near the front flange of the refrigerator body 1 so as to seal the gap around the front surface of the front cold air passage 20.
The seal members 22a to 22i seal the doors 3a to 3c and the storage containers 10a to 10c within a range from a fully closed state to a state in which the doors are pulled out to a thickness of the packing 9 which is not detected by the door switch. Members 22a-22
The front end of i is the front side of the upper and lower openings of the passage forming member added to the surface of the inner surface protruding portion of each door 3a to 3c or the front surface of each storage container 10a to 10c facing each other with a gap provided for sliding the container interposed therebetween. Positioned to keep in contact with the surface of.

The drawing shows that the doors 3a and 3c of the first freezer storage room 5a and the vegetable storage room 6 and the storage containers 10a and 10c are slightly pulled out to the extent described above, and the freezing cycle operates to circulate the cold air 15. It shows the state that is being performed.
In the conventional refrigerator, as described above, the door 3a
In the first frozen storage room 5a and the vegetable storage room 6 in which the openings are opened, the leakage of the cold air 15 and the invasion of the outside air 21 occur actively,
In this embodiment, the cold air 15 is stored in the storage container 10 even in the first frozen storage room 5a and the vegetable storage room 6 in which the door 3a is opened.
On the front side of a to 10c, the front cold air passages 20a to 20c flow and circulate, and the surrounding gaps are seal members 22a to 2c.
Since it is sealed with 2i, the leakage of the cool air 15 to the outside of the refrigerator is suppressed (the invasion of the outside air 21 is also suppressed). Therefore, in the refrigerator of this embodiment, compared with the conventional refrigerator, the drawer-type storage chambers 5a and 6 with the doors 3a and 3c slightly opened.
Also, in the other storage chambers 5b as well, since the temperature inside the storage chambers hardly rises, the stored products in the storage chambers are not damaged. Further, since the internal temperature of the storage chambers 5a, 5b, 6 does not rise, continuous operation of the refrigeration cycle does not occur, and the outside air 21
Since the excessive frost formation of the evaporator 13 due to the invasion of electricity does not occur, the increase in the power consumption of the entire refrigerator is also slight.

FIG. 3 is a vertical sectional side view of a drawer-type storage chamber according to a second embodiment of the refrigerator of the present invention, in which the door of the refrigerator is slightly opened. In this embodiment, the drawer type storage chamber is a large freezing storage chamber 5c which is opened and closed by one rotatable door 3d, and a three-stage sliding storage container 1 is provided.
It has a structure for accommodating 0d to 10f. Similar to the above-described embodiment, the front cold air passages 20d to 20f are formed on the front surface of each storage container 10d to 10f, and the soft and fin-shaped seal members 22a, 22j, 22k, 22f are provided near the front flange of the refrigerator body 1. Inside the refrigerator and the front upper part of the second to third stage storage containers 10e, 10f (front cold air passage 20d-
It is provided in front of the upper and lower openings of 20f).

In this way, even when the door 3d is slightly opened as in the above-described embodiment, the cool air 15 is provided in front of the storage containers 10d to 10f in the front cold air passage 20d.
Since it flows through 20f, the cold air circulation state inside the refrigerator is almost the same as when the door 3d is completely closed, and the cold air leaking out of the refrigerator due to the sealing action of the sealing members 22a, 22j, 22k, 22f. The quantity of 15 is small.
Therefore, also in this embodiment, similarly to the above-described embodiments, it is possible to solve the problems of damage to stored items and increase in power consumption all at once.

FIG. 4 is a vertical side view of a third embodiment of the refrigerator according to the present invention, which is a drawer type storage chamber with the door of the refrigerator slightly opened. In this embodiment, the drawer-type vegetable storage chamber 6 accommodates a storage container 10g that slides integrally with the door 3e. The storage container 10g has its front surface member extended in the vertical direction so as to be in close contact with the inner surface of the inner surface protruding portion of the door 3e, and by providing openings at the upper and lower ends of the front surface of the storage container 10g, the door 3e and the storage container 10g. A front cool air passage 20g is formed therebetween, and the seal members 22g and 22i are arranged so as to extend from the inside of the refrigerator near the front flange of the refrigerator main body 1 and have their tip ends in contact with the outer surface of the inner surface protrusion of the door 3e.

With this arrangement, even when the door 3e is slightly opened, the cold air 15 can be circulated in the refrigerator by the action of the front cold air passage 20g and the seal members 22g and 22i as in the two embodiments described above. The condition is almost unchanged, and there is only a small amount of leakage to the outside. Therefore, problems such as damage to stored products and increase in power consumption hardly appear.

In the refrigerator according to each of the above-described embodiments, the sealing members 22a to 22k are made of soft fins, and the sealing effect is obtained only by the tips of the sealing members 22a to 22k contacting the surfaces of the opposing members. In order to ensure the effect, the materials of the members may be changed or added so that the contact pressure between the tips of the seal members 22a to 22k and the surface of the facing member is increased by magnetic attraction.

The refrigerator according to the present invention as in each of the above-described embodiments has a cooler air temperature than that of a conventional refrigerator when the drawer-type storage chamber door is left slightly open due to an error or the like. Since there is almost no leakage or invasion of outside air and the temperature rise in the refrigerator due to this, damage to stored items can be prevented and an increase in power consumption of the entire refrigerator can be suppressed.

FIG. 5 is a fourth embodiment of the refrigerator according to the present invention, and is a vertical cross-sectional side view of the lower half portion of the refrigerator main body with a part of the refrigerator door and storage container pulled out. . Since the basic structure of the refrigerator and the circulation of cold air with the door closed are almost the same as those of the conventional refrigerator described above, the same reference numerals are given and redundant description will be omitted.

In this embodiment, each drawer-type storage chamber 5 is used.
The outer surface shapes of the side surfaces and the bottom surface of the storage containers 10h to 10j of a and 5b excluding the front surface and the outer surface shape of the bottom surface exposed to the outside in the state of being maximized in a normal use state have a constant cross-sectional shape when viewed from the front. It is molded so that. Furthermore, in order to seal the gap formed around at least both side surfaces and the bottom surface of each of the storage containers 10h to 10j in the pulled-out state,
Soft and fin-shaped sealing members 22c to 22i are also installed inside the refrigerator near the front flange of the refrigerator body 1. The seal members 22c to 22i are used for the doors 3f to 3h and the storage container 1.
In a range in which 0h to 10j are pulled out in a normal use state (a state in which the opening detection is performed by the door switch), the tip ends of the sealing members 22c to 22i are the storage containers 10h to 10j.
It is positioned so that the side surface and the bottom surface of j are always kept in contact with each other near the front surface of the refrigerator body 1.

The drawing shows a state in which the storage containers 10h and 10j of the first frozen storage room 5a and the vegetable storage room 6 are pulled out, and the blower 14 is detected by the open detection by the door switch.
And the circulation of the cool air 15 is stopped. In such a state, in the conventional refrigerator, as described above, when the storage containers 10h and 10j are drawn out, the leakage of the cool air 15 and the subsequent invasion of the outside air occur continuously, but in this embodiment, they are drawn out. In this state, the gaps between the side surfaces and the bottom surface of the storage containers 10h and 10j are the seal members 22c, 22g and 22.
i is sealed by i and the entry path of the outside air 21 is the storage container 10h,
Since it is limited to the upper surface opening of 10j, the flow due to the difference in density is hard to be formed, and the invasion of the outside air 21 becomes small. Particularly in the vegetable storage room 6, since the tip of the sealing material 22g for sealing the upper surface of the storage container 10j comes into contact with the upper front surface of the lid 12 that remains inside the storage container 10j in the pulled-out state, the lid is closed. The outside air 21 is prevented from entering the upper part of the body 12. Therefore, in the refrigerator according to this embodiment, the internal temperature of the storage chamber from which the storage container is pulled out does not rise as compared with the conventional refrigerator, and the damage to the stored items in those storage chambers is reduced. Also, since the temperature inside the storage chamber does not rise, the need for recooling the storage chamber after closing the door is reduced,
It is possible to suppress an increase in power consumption of the entire refrigerator.

FIG. 6 is a vertical side view of a fifth embodiment of the refrigerator according to the present invention, which is a pull-out type storage chamber in which a part of the refrigerator and a storage container are pulled out. In this embodiment, the drawer type storage chamber is a freezing storage chamber 5d, both of which are a sliding type door 3i and a two-stage storage container 1.
Equipped with 0k and 10m. The drawing shows a two-tier storage container 1
0k and 10m show a state where they are pulled out together.
Similar to the above-described embodiment, the outer surface shape of the side surface and the bottom surface of each storage container 10k, 10m is formed so as to have a constant cross-sectional shape when viewed from the front, and further, the soft and fin-shaped sealing member 22a, 22j and 22f are storage containers 10k and 10m
Of the refrigerator main body 1 in the vicinity of the front surface and the lower storage container 10 so as to seal the gaps formed around both side surfaces and the bottom surface of the refrigerator.
It is provided on the upper front part of m.

In the thus constructed refrigerator, even when the door 3i and the storage containers 10k, 10m are pulled out together, the outer surface shapes of both side surfaces and the bottom surface of both storage containers 10k, 10m are constant when viewed from the front. Since the seal members 22a, 22j, and 22f have a good cross-sectional shape and the gaps around them are well sealed, the entry path of the outside air 21 is limited to the upper opening of the storage container 10k in the upper stage. Invasion of the outside air 21 when the containers 10k and 10m are pulled out becomes small. Therefore, also in this embodiment, as in the above-described embodiments, problems such as damage to stored items in the storage chamber and increase in power consumption of the entire refrigerator are reduced.

FIG. 7 is a vertical cross-sectional side view of a sixth embodiment of a refrigerator according to the present invention, which is a drawer type storage chamber in which a door of the refrigerator and a part of a storage container are drawn out. In this embodiment, the pull-out storage compartment is a large frozen storage compartment 5.
e, which is opened and closed by the single rotatable door 3j and accommodates the three-stage sliding storage containers 10n to 10p. The drawings are
It shows a state in which the door 3j is opened and the uppermost storage container 10n is pulled out. Similar to the two embodiments described above, the gaps formed around the respective storage containers 10n to 10p by the outer surface shapes of the both side surfaces and the bottom surface of the storage containers 10n to 10p and the sealing members 22a, 22j, 22k, 22f. The invasion path of the outside air 21 is limited to the upper surface opening of the upper storage container 10n, and the invasion of the outside air 21 when the storage container 10n is pulled out is significantly reduced. Therefore,
Also in this embodiment, as in the above-described two embodiments, problems such as damage to stored items and increase in power consumption of the entire refrigerator are reduced.

As described above, in the refrigerators according to the fourth to sixth embodiments of the present invention, when the storage container is pulled out by opening the door of the pull-out type storage chamber in the normal use state, the conventional refrigerator is used. In comparison, it is possible to prevent outside air from entering and to reduce the temperature rise inside the refrigerator, thus preventing damage to stored items in the storage room with the door open and reducing the increase in power consumption of the entire refrigerator. You can

8 to 12 show a seventh embodiment of the refrigerator according to the present invention.
FIG. 8 is a vertical sectional side view of the lower half of the refrigerator main body with all doors closed, and FIG. 9 shows the refrigerator main body with some doors and storage containers pulled out. The vertical side view of the lower half, FIG. 10 is the vertical side view of the cold air passage switching section,
FIG. 11 is a block diagram of the control device, and FIG. 12 is a flowchart of control processing executed by the control device. The basic structure of the refrigerator in this embodiment is almost the same as that of the conventional refrigerator already described with reference to FIGS. 14 to 16. The same parts are designated by the same reference numerals, and overlapping description will be omitted. In this embodiment, each storage room 5a, 5b,
6 are newly provided in the middle of the cold air circulation path consisting of the supply path 16 for the cool air 15 and the return path 17.
4c and passage blocking means 25. The passage switching means 24a, 24b are, as shown in FIG. 10, a switching valve operation 24a-2 operated by an electromagnetic operating device 24a-1.
The cold air circulation direction is switched by. Although not shown in the drawings, the passage switching means 24c and the passage blocking means 25 are configured to change or connect the cold air passage by a valve.

As shown in FIG. 11, the control device is mainly composed of a microcomputer 26, and as shown in FIG. 12, a cold storage room temperature sensor 27a, a freezing storage room temperature sensor 27b, and an outside temperature. The blower 18, the compressor 18, the heater 2 based on the detection signals from the sensor 27c, the cold storage room door switch 28a, the first freezing storage room 5a door switch 28b, and the second freezing storage room 5b door switch 28c.
9. Refrigerating / storage room passage switching means 24d and first and second
The switching operation of the freezing / storage room passage switching means 24a, 24b is controlled. The door detecting means 28d of the vegetable storage chamber 6 mechanically links with the passage switching means 24c and the passage blocking means 25 to operate the passage switching means 24c and the passage blocking means 25.

As shown in FIG. 8, all the doors 3a to 3c.
The passage switching means 24a to 24c are in the closed state.
Also, the passage blocking means 25 is in the open state, and stops and continues the circulation of the cool air 15 in accordance with the intermittent operation of the refrigeration cycle, as in the conventional refrigerator.

As shown in FIG. 9, the door 3c of the vegetable storage chamber 6 is shown.
When the container was opened (which can be opened in any of the storage chambers), the refrigeration cycle was operating or the refrigeration cycle was operating originally due to an increase in the internal temperature of the vegetable storage chamber 6 with the door 3c opened. In this case, in this embodiment, since the stop control of the blower 14 is not performed by detecting the opening of the door switch 28d, the circulation of the cool air 15 by the blower 14 is continued. However, the passage switching means 24c and the passage blocking means 25 switch and cut off the supply passage 16 and the return passage 17 in conjunction with the opening of the door 3c to supply the cold air 15 to be supplied to the vegetable storage chamber 6 with the door 3c opened. Is circulated directly from the supply passage 16 to the return passage 17 so as not to circulate in the vegetable storage chamber 6 with the door 3c opened, and the frozen storage chambers 5a, 5b with the doors 3a, 3b closed.
The circulation of the cool air 15 is continued by the path of the supply passage 16 and the return passage 17 with respect to other storage chambers such as b (including storage chambers not of the pull-out type). However, when the same cool air 15 continuously circulates in a plurality of storage rooms (for example, the cold storage room 4 and the vegetable storage room 6 in a normal refrigerator), the cool air 15 is used for the storage room with the door opened. By-pass and flow from the supply passage 16 of the storage chamber to the supply passage 16 of the next storage chamber (when the next storage chamber is present) or the return passage 17 of the storage chamber (when the storage chamber is the last in the route) Switch the passage to. Therefore, in the storage room where the doors are not opened, the inside of the storage room is cooled in substantially the same manner as when the doors of all the storage rooms are closed, so that a large fluctuation in the internal temperature of the conventional refrigerator is prevented. It does not occur, and the damage to the stored items in those storage chambers can be reduced. Further, the operation of the refrigeration cycle is a normal intermittent operation, although the operation time is extended by the heat loss in the vegetable storage room 6 with the door 3c opened, and the blower 14 operates while the compressor 18 such as the conventional refrigerator operates. Since it does not become an irregular operation that stops,
The increase in the power consumption of the refrigerator as a whole due to the opening of the storage room can be suppressed.

The structure of the refrigerator and the storage room in which the door is opened have been described above only in a specific case. However, even if the structure of the refrigerator is deformed or the doors of other storage rooms are opened, the same operational effect can be obtained. The promise is clear.

As described above, in the refrigerator of this embodiment, when the door of any of the storage chambers is opened, the temperature fluctuations in the storage chambers including the drawer type, which are not opened, are extremely small. There is very little damage to stored items in the pull-out storage room that has not been opened and increase in power consumption of the entire refrigerator.

Although the first to seventh embodiments of the present invention have been described so far, by combining the configurations of these plurality of embodiments, damages to stored items and increase in power consumption under various conditions for opening a door. It will be possible to realize a refrigerator that can reduce

FIG. 13 shows a refrigerator according to an eighth embodiment of the present invention constructed on the basis of the above-mentioned idea, in which the lower half of the refrigerator main body is shown with the door of each storage chamber open. It is a vertical side view. In this embodiment, the basic structure of the refrigerator and the circulation of cold air with the door closed are the same as those of the conventional refrigerator or the first and seventh embodiments already described,
These components will be described with the same reference numerals.

The drawing shows the first and second frozen storage chambers 5a,
The doors 3a and 3b of 5b are slightly opened, and the vegetable storage chamber 6 shows a state in which the door 3c and the storage container 10c are largely pulled out. In each drawer type storage room 5a, 5b, 6
Front cold air passages 20a to 20c extending in the up-down direction are formed between the doors 3a to 3c and the storage containers 10a to 10c, and the bottoms and side surfaces of the storage containers 10a to 10c except the front surface of the storage container 10a to 10c are pulled out to the outside of the refrigerator. The surface shape is formed to have a constant cross-sectional shape when viewed from the front, and the front cold air passages 20a-2
0c sealing members 22a to 22i for sealing the front surface are provided in such a shape and arrangement as to also seal the gap between the bottom surface and both side surfaces of the storage container 10, and further cool air to each of the storage chambers 5a, 5b, 6 is provided. Passage switching means 24 a to 24 c and a passage blocking means 25 are installed in the supply passage 16 and the return passage 17 of 15.

In the illustrated state, since the door 3c and the storage container 10c of the vegetable storage chamber 6 are largely pulled out, the cold air 15 is provided with the passage switching means 24c so as to circulate around the vegetable storage chamber 6 and circulate. The passage blocking means 25 operates, and the first and second frozen storage chambers 5a and 5b are in a state where the doors 3a and 3b are slightly opened, but the cold air 15 is circulated.

In the vegetable storage chamber 6, the invasion of the outside air 21 into the storage after being pulled out is suppressed by the sealing members 22g and 22i which also serve as the sealing of the bottom surface and both side surfaces of the storage container 10c. First and second frozen storage rooms 5a, 5
Although the doors 3a and 3b are slightly opened in FIG. 5b, the front cool air passages 20a and 20b and the seal member 22 for sealing the front cold air passages 20a and 20b are provided.
Cooling of the cold air 15 and invasion of the outside air 21 can be suppressed by a to 22f, so that the inside of the refrigerator is cooled well.
Therefore, as already described in each of the above embodiments, the vegetable storage chamber 6 and the doors 3a, 3 having the door 3c opened as compared with the conventional refrigerators.
Since the temperature inside the freezing storage chambers 5a and 5b where b is slightly opened does not rise so much that the stored items are not damaged, and the refrigeration cycle is close to normal intermittent operation, the door is opened. The increase in power consumption of the refrigerator as a whole will also be reduced. Then, such an effect can be similarly obtained in a refrigerator in which the method of opening the door of each storage chamber is different from that of this embodiment.

The structure of the refrigerator and the storage room in which the door is opened have been described above in a specific configuration. However, even if the structure of another refrigerator or the door of another storage room is opened, the effect depending on the condition of opening the door is effective. Although the appearances are slightly different, the basic effect that can reduce damage to stored items and increase in power consumption can be expected in common.

In each of the above-mentioned embodiments, the upper half part of the refrigerator body is commonly used as a fixed shelf type refrigerating storage room, and the lower half part is made up of a plurality of other drawer type storage rooms.
Refrigerators of different overall structure with one or more pull-out storage compartments (for example, the upper or middle part of the refrigerator body is a fixed shelf freezer storage compartment and a cold storage compartment, and the lower part of them is a pull-out storage compartment for vegetables. It is clear that the same effect can be expected by applying the present invention to a room or the like).
