Description

  The present invention relates to a refrigerator, and more particularly to a refrigerator including a drawer-type egg storage case.

  Generally, a refrigerator includes an egg tray that holds and stores eggs. The egg tray is provided with a plurality of holes, and the lower protrusions of the eggs or egg packs are held one by one in the holes. Here, the egg pack is a plastic packaging container for storing and selling a plurality of eggs.

  As described above, since the egg tray requires holes for holding the eggs one by one, when a large number of eggs are to be stored, a relatively large space is required.

  Therefore, a multi-stage egg tray that can change the number of stages as required has been proposed (see, for example, Patent Document 1). According to the egg tray described in Patent Document 1, a large number of eggs can be stored in a limited space. However, a storage space for two stages is required for storing eggs.

  By the way, in a refrigerator with a relatively narrow door such as a refrigerator having a double door, a egg tray is installed in a drawer inside the storage room without installing an egg tray in a door pocket provided on the inner wall of the door. Is done. This solves problems such as being difficult to use eggs that are used in everyday life when they are in the door pocket, and problems of easily deteriorating egg quality due to vibration of opening and closing of the door.

  As another conventional configuration, the egg storage case includes two parts, an egg tray and a storage case (see, for example, Patent Document 2).

  6 is a front view of the conventional refrigerator with the door opened, and FIG. 7 is a perspective view of the egg tray and egg storage case of Patent Document 2. As shown in FIG.

  As shown in FIG. 6 and FIG. 7, the conventional refrigerator 300 has a refrigerator compartment 302, an ice making room 303 and a changeable changeover room 304 arranged in parallel inside the heat insulating box 301, and further below it. Are provided with a vegetable compartment 305 and a freezer compartment 306 at the bottom.

  The refrigerator compartment 301 is provided with a French-type rotary door 307 and is opened from the center to the left and right. The refrigerator compartment 301 is provided with a plurality of cabinet shelves 308. The lower tier includes a chilled case 309, an upper case 310 and a lower case 311 configured by two upper and lower stages, and a water supply tank 312 for automatic ice making. And. Each case is provided with a wall surface so as to have a substantially hermetically sealed structure independently when stored.

  The upper case and the lower case, which are composed of two upper and lower stages, are set to have the same height, and can be stored by replacing the upper case and the lower case. One is the egg tray 313. Is provided inside the case. The egg tray 313 is used by placing the eggs in the upper case 310 or the lower case 311 by changing the front and back of the egg tray 313 depending on whether the eggs are stored separately or the egg pack containing the eggs is stored. .

  The refrigerated room 301 is often set at a refrigerated temperature of 3 ° C. to 5 ° C. for the purpose of storing refrigerated foods and bottles, and the chilled case 309 stores fresh ingredients such as meat fish and paste products such as chikuwa. In order to maintain freshness, the temperature is often set to 0 ° C. to 1 ° C. at a lower temperature than the refrigerator compartment 302. Further, since the upper case 310 and the lower case 311 are intended for storing eggs and refrigerated items, the temperature is set to be the same level as that of the refrigerated room 302 so as not to freeze.

  In particular, when the eggs are frozen, the quality of the eggs is greatly reduced and the eggs must be disposed of, and the anti-freezing partition 314 below the lower case 311 has a temperature compensation. A heater (not shown) is embedded to control the temperature below the lower case 311 so as not to decrease too much.

Further, as shown in FIG. 7, the conventional egg storage case includes two parts, an egg tray 313 and a storage case 311.
JP 2002-87483 A Japanese Utility Model Publication No. 58-41485

  In recent years, the refrigerator is required to save space and have a large capacity, and the heat insulating partition 314 is designed to be as thin as possible in order to reduce the invalid volume. Therefore, the heat insulating partition 314 suppresses heat conduction in the ice making chamber 303. It has become difficult to ensure a sufficient thickness.

  As described above, the use of the temperature-compensated heater increases the amount of power consumed by the refrigerator, increases the burden on the user's electricity bill, and adversely affects the environment, such as an increase in CO2 emissions. Further, if the thickness of the heat insulating partition 314 is sufficiently secured, the internal volume of the refrigerator is reduced and the bottom surface of the refrigerator compartment 302 is increased, so that each shelf 308 and the door pocket 315 are suitable for short women and children. There was a problem that became harder to use.

  The present invention solves the above-mentioned conventional problems, while maintaining the conventional merit with a drawer-type egg storage case in the warehouse, maintaining the quality of eggs, securing the internal volume with a thin heat insulating partition, The object is to provide an easy-to-use and energy-saving refrigerator that suppresses the bottom height of the refrigerator compartment.

  In order to solve the above-described conventional problems, the refrigerator of the present invention has a heat insulation box configured by partitioning a first storage room having a refrigeration temperature in the upper part and a second storage room having a refrigeration temperature in the lower part with a heat insulating partition. And an interior storage space divided into a drawer-type upper case and a lower case at the lowermost inside of the first storage chamber and at the upper part of the heat insulating partition, the upper case being an egg storage case The lower case is set at a lower temperature than the upper case.

  By this, even if the surface temperature of the heat insulating partition is lowered due to the heat conduction effect from the second storage chamber which is the freezing temperature, the temperature of the egg storage case is prevented from being lowered by performing air insulation through the lower case. Can do. In addition, the lower case can be set to a temperature lower than that of the upper case by cooling from the heat insulating partition without using a complicated cooling air passage configuration or air passage control device. Therefore, since the temperature compensation heater is not used, the amount of power consumption can be suppressed, and the adiabatic partition is not designed to be thick, so that the internal volume is not reduced.

  In order to solve the above-described conventional problems, the refrigerator of the present invention is configured by partitioning a first storage room having a refrigeration temperature in the upper part and a second storage room having a refrigeration temperature in the lower part by an insulating partition. A heat insulating box, and a storage space divided into a drawer-type upper case and a lower case at the uppermost part of the heat insulating partition at the lowermost inside of the first storage chamber, and the upper case is an egg storage case The lower case is a chilled case set at a lower temperature than the upper egg case.

  As a result, even if the surface temperature of the heat insulating partition is lowered due to the heat conduction effect from the second storage room, which is the freezing temperature, the temperature of the egg storage case is prevented from being lowered by performing air insulation through the lower chilled case. can do. Further, the chilled case can be set to a temperature lower than that of the upper case without using a complicated cooling air passage configuration or air passage control device by cooling from the heat insulating partition. Therefore, since the temperature compensation heater is not used, the amount of power consumption can be suppressed, and the adiabatic partition is not designed to be thick, so that the internal volume is not reduced. Furthermore, chilled cases require higher temperature control accuracy due to the nature of the stored items, but the chilled case, which is the lower case, has a thin shape, so food in the chilled case is contained in the chilled case. Since the possibility of being stored in an overlapping manner is reduced, the temperature of food in the chilled case can be controlled with higher accuracy. Furthermore, when a relatively large chilled case is provided in the first storage room at the refrigeration temperature, a plurality of storage cases for chilled cases are arranged in the first storage room at the refrigeration temperature. By using a shape dedicated to thin accessories, it is possible to store large and small items separately, making it easier to manage small foods. Therefore, wasteful disposal of food can be reduced.

  The refrigerator of the present invention can provide an easy-to-use refrigerator that is energy-saving and has a large internal volume, while preventing freezing of eggs and maintaining stable quality.

  The invention according to claim 1 is a heat insulating box configured by partitioning a first storage chamber having a refrigeration temperature at an upper portion and a second storage chamber having a refrigeration temperature at a lower portion with a heat insulating partition, and the first A storage space divided into a drawer-type upper case and a lower case at the uppermost part of the heat insulating partition at the lowermost inside of the storage room, and the upper case is an egg storage case, and the lower case is By setting the temperature lower than that of the upper case, air insulation is performed through the lower case even if the surface temperature of the heat insulating partition is lowered due to the heat conduction effect from the second storage chamber which is the freezing temperature. Can prevent temperature drop of the egg case. In addition, the lower case can be set to a temperature lower than that of the upper case by cooling from the heat insulating partition without using a complicated cooling air passage configuration or air passage control device. Therefore, since the temperature compensation heater is not used, the amount of power consumption can be suppressed, and the adiabatic partition is not designed to be thick, so that the internal volume is not reduced.

  According to a second aspect of the present invention, there is provided a heat insulating box configured by partitioning a first storage chamber having a refrigeration temperature at an upper portion and a second storage chamber having a refrigeration temperature at a lower portion with a heat insulating partition, and the first A storage space divided into a drawer-type upper case and a lower case at the uppermost part of the heat insulating partition at the lowest inside of the storage room, and the upper case is an egg storage case, and the lower case is By being a chilled case set at a lower temperature than the upper case, the chilled case is a lower case even if the surface temperature of the heat insulating partition is lowered due to the heat conduction effect from the second storage chamber that is the freezing temperature. It is possible to prevent the temperature drop of the egg storage case by performing air insulation through the. In addition, the chilled case is cooled from the heat insulating partition, so that the temperature setting is lower than the upper case without using a complicated cooling air passage configuration and air passage control device, and no temperature compensation heater is used. The power consumption can be reduced, and the insulation partition is not designed to be thick, so the internal volume of the cabinet is not reduced, freezing of the eggs can be prevented and stable quality can be maintained. It becomes possible to provide a large and easy-to-use refrigerator. Furthermore, chilled cases require higher temperature control accuracy due to the nature of the stored items, but the chilled case, which is the lower case, has a thin shape, so food in the chilled case is contained in the chilled case. Since the possibility of being stored in an overlapping manner is reduced, the temperature of food in the chilled case can be controlled with higher accuracy. Furthermore, when a relatively large chilled case is provided in the first storage room at the refrigeration temperature, a plurality of storage cases for chilled cases are arranged in the first storage room at the refrigeration temperature. By using a shape dedicated to thin accessories, it is possible to store large and small items separately, making it easier to manage small foods. Therefore, wasteful disposal of food can be reduced.

It is possible to prevent the case from being stored in a relatively cold part and accidentally freezing the egg. In particular, the case is removable from the interior so that it can be washed, and can be prevented from being mistakenly placed after washing. Furthermore, since the user can recognize the difference in the usage of the case and can determine without any hesitation what is contained in which case, the convenience of the user can be improved.

  According to a fourth aspect of the present invention, in the invention of the third aspect, the storage height of the upper case is 7 cm or more, and the storage height of the lower case is 6 cm or less, so that the user can It is assumed that the egg pack is not high enough to be stored in the lower case, so that freezing of the egg due to misuse can be suppressed.

That is, by enclosing the egg storage case in the left-right direction with the water supply tank and the chilled case, temperature drop of the egg storage case can be further prevented and temperature fluctuation can be further reduced.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings. The same reference numerals are given to the same configurations as those of the conventional example or the embodiments described above, and detailed descriptions thereof will be omitted. The present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a front view of a refrigerator according to Embodiment 1 of the present invention, FIG. 2 is a front sectional view of the refrigerator according to Embodiment 1 of the present invention, and FIG. 3 is Embodiment 1 of the present invention. FIG. 4 is a partial perspective view of the refrigerator compartment of the refrigerator according to Embodiment 1 of the present invention.

  As shown in FIGS. 1 to 4, the refrigerator 100 includes an outer box 101, an inner box 102, a heat insulating box body 110 filled with a heat insulating material 103 such as hard urethane foam foamed inside, and a heat insulating door body 111 that can be opened and closed. A storage room is provided in the interior, and the storage room has a refrigerator room 112 (first storage room), an ice making room 113 (second storage room), and an upper freezing room 114 arranged in parallel from left to right. Furthermore, a freezer compartment 115 and a vegetable compartment 116 are provided at the bottom.

  Each storage chamber is partitioned by a heat insulating partition 120 between chambers having different temperature zones, and a storage partition having a similar temperature zone is partitioned by a structural partition 121 so that air and heat can freely enter and exit.

  Further, the heat insulating door body 111 provided at the opening of each storage room is provided with a so-called French-type heat insulating door body 111a on the left and right sides that opens and closes in the left-right direction in the refrigerator compartment 112.

  In addition, the ice making chamber 113, the upper freezing chamber 114, the freezing chamber 115, and the vegetable chamber 116 are each provided with a heat insulating door body 111b, and an ice making case 113a, an upper freezing case 114a, and a plurality of freezing cases are provided therein. A case 115a and a plurality of vegetable cases 116a are provided. When each heat insulating door is pulled out, each case is pulled out at the same time, so that food can be easily taken in and out.

  The refrigerator compartment 112 includes a door pocket 123 on the inner side of the heat insulating door body 111a, and can store beverages, bottles, and the like. In addition, a plurality of internal shelves 124 are provided inside, and the lowermost stage is an internal storage space 125 that is composed of a relatively large chilled case 130 slidable back and forth in order from the right, and two upper and lower stages. An upper case 131, a lower case 132, and a water supply tank 133 for automatic ice making are provided. Each case is provided with a wall surface so as to have a substantially hermetically sealed structure independently when stored. The border between the chilled case 130, the upper case 131, and the lower case 132 is the same as the left and right borders of the French heat insulating door 111a, and one of the cases can be taken in and out by opening one of the doors. ing.

  In addition, in the storage space divided into the drawer-type upper case 131 and the lower case 132 in the uppermost part of the heat insulating partition 120 at the lowermost inside of the refrigerator compartment 112 (first storage chamber), the cold storage is forcedly cooled. It is not a space to be introduced.

  The upper case 131 is an egg storage case, and an egg tray (not shown) is detachably disposed therein. The egg tray is used by changing the front and back of the egg tray and storing it in the upper case 131 depending on whether the egg is stored separately or an egg pack containing eggs.

  The upper case 131 can store at least 10 eggs, preferably 14 eggs in two rows in the depth direction. In the case where 14 eggs can be stored, even if 4 eggs remain in the egg storage case, it is possible to store 10 more egg packs.

  According to the statistics website of the Japan Poultry Association, quoted from the Ministry of Internal Affairs and Communications' household survey shows the egg consumption per person per year. According to this, the egg consumption per person per day in 2007 is 27.2 g. It can be seen that approximately ½ eggs are consumed, assuming that eggs are approximately 60 g per egg. However, since it is not common to use ½ eggs and leave ½ eggs, it seems reasonable to consider that one egg is consumed on average every two days.

  Further, eggs are generally sold in the form of 10 packs (2 rows x 5 plastic containers).

  With an average family structure of four large refrigerator purchasers, the number of eggs required for the refrigerator is at least 10. In this case, the next egg pack cannot be stored until the eggs are completely used up. In addition, when 12 eggs can be stored, the next egg can be stored when 2 eggs remain, but the average amount used by 4 family members is 4 at a time. If there are two, it may be unsatisfactory.

  Therefore, by making the upper case 131 capable of storing 10 packs and 4 or more, the user can effectively make an egg purchase cycle and can always buy and eat fresh eggs. It becomes possible. That is, when the user is a family of four, a newly purchased 10-pack egg can be stored in the upper case 131 in a state where one egg is held in one family. improves.

  Furthermore, since two holding unit rows arranged in seven are provided, it becomes easy to separate and manage old eggs and newly purchased new eggs. Furthermore, by storing the remaining eggs in the front-rear direction and storing the next egg pack in the back, it can be consumed without making mistakes in order from the old eggs, so wasteful food can be prevented from being discarded, This improves the convenience for the user and contributes to the environment. Moreover, since it is possible to store the eggs including the spare eggs in one case, it is not necessary to use a space such as providing egg cases in two places, so that a space for other foods can be secured.

  The lower case 132 has the same width (left-right direction) as the upper case 131, but the height is set to be lower than that of the upper case 131. Thereby, it can be prevented that the upper case 131 and the lower case 132 are mistakenly inserted and the egg storage case is stored in a relatively low temperature portion and the egg is frozen by mistake. In particular, the case is removable from the interior so that it can be washed, and can be prevented from being mistakenly placed after washing. Furthermore, since the user can recognize the difference in the usage of the case and can determine without any hesitation what is contained in which case, the convenience of the user can be improved. Specifically, since the upper case 131 having a high height can be determined to store eggs, the user does not get lost when taking out the eggs.

  The upper case 131 has a height at which eggs and egg packs can be stored at a height of 7 cm or more, and the lower case 132 has a storage height at which eggs cannot be mistakenly inserted by 6 cm. The height of a single egg is approximately 6 cm, but the clearance from the bottom surface where the egg tray is installed is required to be about 0.5 cm.

  By the way, in addition to fresh products such as meat fish, the chilled case 130 has a wide variety of foods such as processed foods such as ham and wiener, marine products such as chikuwa and kamaboko, chilled foods such as raw noodles and prepared dishes, and yogurt. Shapes vary from bags to trays and sizes.

  In such a chilled case 130 in which various foods are stored, particularly small items are hidden behind other foods and lost, and the expiry date has passed and must be discarded. It often happens. As in this embodiment, a plurality of chilled storage cases, such as a large chilled case 130 and a lower case 132, are arranged, and the lower case 132 has a shape dedicated to thin accessories. By placing large items in the chilled case 130 and small items in the lower case 132, it is possible to store large items and small items separately, and it is easy to manage small items. Therefore, wasteful disposal of small food items can be reduced.

  By the way, the vicinity of the heat insulating partition 120 that is a member that partitions the refrigerator compartment 112, the ice making chamber 113, and the upper freezer compartment 114 has a temperature fluctuation. However, as in the present embodiment, the upper case 131 which is an egg storage case is disposed on the lower case 132, that is, the egg storage case is not disposed directly above the heat insulating partition 120, but is accommodated in the housing space. By arranging the upper case 131 that is an egg storage case with the lower case 132 sandwiched therebetween, the temperature fluctuation in the upper case 131 can be reduced, the temperature fluctuation of the egg itself can be further reduced, and the egg Quality can be maintained.

  By the way, the inside shelf 124 has different depth dimensions on the left and right sides from the opening of the refrigerator compartment 112, and the left depth dimension is longer than the right depth dimension. The inside shelf 124 is set to have a depth so as not to interfere with each door pocket 123.

  Moreover, each case arrange | positioned in the store | warehouse | chamber storage space 125 of the lowest stage in the refrigerator compartment 112 respond | corresponds to the shape of the shelf 124 in a warehouse. That is, the left and right cases have different depth dimensions.

  Specifically, the chilled case 130 has a small depth, and the upper and lower upper cases 131 and 132 are set to have a larger depth than the chilled case 130.

  As a result, the upper case 131 which is an egg storage case has a long depth dimension, and can store 14 or more eggs in two rows, improving usability, and the small case chilled storage of the lower case 132 in the depth direction. Since the capacity can be secured, the capacity can be increased without making it difficult to see small items overlapping.

  Although the upper case 131 has a separate egg tray, it may be an integrally structured case as shown below.

  FIG. 5 is a perspective view of the integrated egg storage case of the refrigerator in the first embodiment.

  As shown in FIG. 5, the integrated egg storage case 140 includes a plate-like portion 141, a holding portion 142, a wall portion 143, and a slide portion 144.

  The plate-like portion 141 is a member that spreads in a horizontal plane in the egg storage case 140.

  A plurality of holding portions 142 are members that are provided in the plate-like portion 141 and are recessed in a bulging shape below the plate-like portion 141. The holding portion 142 is configured integrally with the plate-like portion 141.

  The wall portion 143 is a member that is provided integrally with the plate-like portion 141 and extends in a direction perpendicular to the periphery of the plate-like portion 141. That is, the wall part 143 and the plate-shaped part 141 are members configured integrally.

  The slide portion 144 is a member that is provided integrally with the wall portion 143 at the lower ends of the left and right wall portions 143 and extends in the depth direction. The slide portion 144 is a member that allows the egg storage case 140 to be pulled out in the depth direction while suppressing vibration.

  As described above, in the egg storage case 140, the wall portion 143 and the plate-like portion 141 are integrally formed. That is, since the storage case and the egg tray are integrated, it is possible to stably hold the eggs without moving the egg tray in the storage case. Further, the storage case and the egg tray can be molded integrally, and the manufacturing cost can be reduced.

  Moreover, since an egg is stored in the space divided by the plate-shaped part 141 and the wall part 143, it becomes possible to suppress that the germs adhering to the egg shell adhere to other foodstuffs. Further, when the egg jumps out of the holding portion 142 due to vibration or the like when being pulled out, it is possible to prevent the egg from falling out of the egg storage case 140. Furthermore, when an egg is broken in the egg storage case 140, the contents of the egg can be prevented from flowing out of the egg storage case 140.

  Note that the egg storage case 140 of the present embodiment includes a slide part 144 provided at the lower ends of the left and right wall parts 143, but in the depth direction outside the intermediate position in the height direction of the left and right wall parts 143. You may provide the convex slide part extended in this. That is, as long as the egg storage case 140 can be pulled out in the depth direction and the vibration of the egg storage case 140 can be suppressed when being pulled out, the egg storage case 140 includes any slide portion. Also good.

  In addition, a water supply tank 133 for automatic ice making is arranged on the left side when viewed from the front, which is one space on the side of the upper case 131, and relatively relatively on the right side when viewed from the front, which is the other space on the side. By arranging the larger chilled case 130, the water in the water supply tank 133 arranged on the left side of the upper case 131 has a large heat capacity, and the effect of heat conduction from the inner box can be reduced. By performing air insulation through the chilled case 130 disposed in the direction, temperature drop of the egg storage case can be further prevented and temperature fluctuation can be further reduced. That is, by enclosing the egg storage case in the left-right direction with the water supply tank 133 and the chilled case 130, temperature drop of the egg storage case can be further prevented and temperature fluctuation can be further reduced.

  Regarding the refrigerator configured as described above, the temperature setting of each room is set to 2 ° C. to 5 ° C. in the refrigerator compartment 112, the chilled case 130 in the same cabinet is 0 ° C. to 1 ° C., and the upper case 131 is 2 ° C. The lower case 132 is set to 0 ° C to 1 ° C. Further, the lower ice making chamber 113, the upper freezing chamber 114, and the freezing chamber 115 are set to around -20 ° C. The vegetable compartment 116 is set to a temperature slightly higher than that of the refrigerator compartment 112 and is set to 4 ° C to 7 ° C.

  Although the temperature of the chilled case is required to be higher due to the nature of the stored items, the chilled case, which is the lower case 132, has a thin shape, and therefore the food in the chilled case is contained in the chilled case. Since the possibility of being stacked and stored is reduced, the temperature of food in the chilled case can be controlled with higher accuracy.

  Each chamber is temperature-controlled by a cooling system (not shown), a cooling air passage (not shown), and a control means (not shown). The cooling of the refrigerator compartment 112 is controlled by a damper (not shown) by the amount of cold air distributed to the refrigerator compartment 112 according to the temperature detected by a temperature sensor (not shown) provided in the refrigerator compartment 112.

  The chilled case 130 and the lower case 132 are affected by heat conduction from the ice making chamber 113 and the upper freezing chamber 114, which are freezing temperatures, and the surface temperature of the heat insulating partition 120 is lowered by not using a conventionally used heater. Thus, a relatively low temperature can be achieved even in the refrigerator compartment 112 without using a complicated cooling air passage configuration or air passage control device.

  Moreover, the upper case 131 can prevent the temperature drop of the egg storage case without using a heater by performing air insulation through the lower case 132. As a result, the power consumption of the heater can be suppressed, and since the heat insulating partition is not designed to be thick, it is possible to prevent egg freezing and maintain stable quality without reducing the internal volume. It becomes possible to provide an easy-to-use refrigerator with energy saving and large internal volume.

  That is, the lower case 132 is a chilled case that can be maintained at a lower temperature than the upper case 131 because there is no heating means (heater), and the upper case 131 has no heating means (heater) and is 0 ° C. or higher. It is an egg storage case that can be maintained in

  In the present embodiment, the lower case 132 is a chilled case of 0 to 1 ° C. However, from the gist of the present invention, the lower case 132 is set at a lower temperature than the upper case 131. The lower case 132 is not necessarily required to be in the chilled temperature range, and the lower case 132 may be set to a temperature range of 0 to 3 ° C., for example.

  In addition, the same effect can be acquired even if it is another layout if the storage space in the refrigerator in the refrigerator compartment is in contact with the freezing temperature. For example, the freezer compartment below the refrigerator compartment may not be divided into an ice making compartment and an upper freezer compartment.

  Moreover, the same effect can be acquired even if the upper case and the lower case are compartments configured to fill the full width of the refrigerator.

  The present invention is applicable to a refrigerator provided with a drawer-type egg storage case.
