Description

Refrigerator and egg storage box Field of invention

The present invention relates to a refrigerator.

Background of the invention

In general, the refrigerator is provided with an egg rack that can hold the eggs. However, the rack is provided with a plurality of holes, each of which holds a raised portion below the egg or egg box. The so-called egg box refers to a plastic packaging container for storing and selling a plurality of eggs.

As described above, since it is necessary to hold the eggs one by one on the egg rack, a large space is required when a large number of eggs are to be accommodated.

Therefore, there has been proposed a multi-layered egg rack in which the number of layers can be changed as needed (refer to, for example, Patent Document 1). The egg rack disclosed in Patent Document 1 can accommodate a large number of eggs in a limited space. However, when storing eggs, a storage space of 2 layers will be required.

Further, in a refrigerator having a single door width such as a refrigerator having left and right opposite doors, an egg rack is not provided in a gantry provided on the inner wall of the door, and an egg rack is provided in a drawer inside the storage compartment. Therefore, when it is installed in the gantry, it is located at a higher position, and it can solve the problem that the eggs used for daily use are difficult to access and the vibration of the opening and closing of the door causes the egg quality to be easily deteriorated.

Further, the conventional egg storage case of another structure is composed of two parts of an egg rack and a storage case (see, for example, Patent Document 2).

Fig. 20 is a front view showing a state in which a refrigerator door is opened, and Fig. 21 is a perspective view of an egg rack and an egg storage box of Patent Document 2.

As shown in FIG. 20 and FIG. 21, in the conventional refrigerator 400, the refrigerator compartment 402, the ice making compartment 403, and the changeable setting switching chamber 404 are arranged side by side in the inside of the heat insulating box 401, and further, the refrigerator compartment 400 is provided below. There is a fruit and vegetable compartment 405, and the lowermost layer is a freezer compartment 406.

The heat insulating box 401 is provided with a French revolving door 407 which is openable from the center to the left and right. Further, the heat insulating box 401 is provided with a plurality of box inner frames 408, and includes a lowermost refrigerating box 409, an upper layer box 410 and a lower layer box 411, and a water supply tank 412 for automatic ice making. Each of the casings is provided with a wall surface and can be independently provided in a slightly closed structure during storage.

The upper layer case 410 and the lower layer case 411 are composed of the upper and lower layers and have the same height dimension. The upper case 410 and the lower case 411 are replaceable, and one of them is provided with an egg rack 413 inside the case. The egg rack 413 can change the front and back of the egg rack 413 and store the upper case 410 or the lower case 411, depending on when the egg is stored and when the egg box containing the egg is stored.

The refrigerating compartment 401 is set to a refrigerating temperature of 3 ° C to 5 ° C for the purpose of storing refrigerated foods and bottles. The refrigerating box 409 is often used for storing fresh food such as fish and meat, fish paste products such as bamboo wheels, and the like, and is set to be 0 ° C to 1 ° C lower than the low temperature of the refrigerating chamber 402 in order to maintain freshness. Further, the upper case 410 and the lower case 411 are for the purpose of accommodating eggs and refrigerated small items, and the temperature is set to the same level as that of the refrigerating chamber 402, so that the temperature is not frozen.

In particular, if the egg is frozen, the quality will be greatly reduced, and it will be discarded. The prevention of egg freezing is extremely necessary, so that the heat-insulating plate 414 under the lower casing 411 is embedded with a temperature-compensating heater (not shown) to control the temperature of the lower portion of the lower casing 411 not to be too low.

Secondly, in recent years, the market has required refrigerators to save space and have large capacity. Therefore, in order to reduce the ineffective volume, the heat shield 414 is also designed to be as thin as possible. As a result, the heat shield 414 has gradually failed to ensure that the thickness of the heat conduction of the ice making chamber 403 can be suppressed.

Moreover, if the thickness of the heat shield 414 is sufficiently ensured, the internal volume of the refrigerator will be reduced, and the bottom surface of the refrigerator compartment 402 will also be improved. Therefore, the inner frame 408 and the gantry 415 of each box will gradually cause inconvenience to the petite women and children. , becoming a problem.

Moreover, the use of a temperature-compensated heater increases the power consumption of the refrigerator, increases the burden on the user's electricity bill, and causes an increase in carbon dioxide emissions and the like, which is also a problem.

Further, in the configuration of Patent Document 2, the number of parts will be increased as compared with the egg storage case in which the egg holder 413 and the lower case 411 are composed of one part, and there is also a problem that the manufacturing cost is increased.

Moreover, the egg rack 413 is different from the case where the egg box containing the egg is stored, and the back of the egg rack 413 is changed and the lower case 411 is placed. Therefore, when the user stores the egg, it may be necessary to take out the egg rack 413 and change the back of the watch to load the egg rack 413.

Moreover, an activity space is required between the lower layer box 411 and the egg rack 413 so that the user can easily take out the egg rack 413 from the lower layer box 411. Therefore, the egg rack 413 can move the distance of the movable space in the lower casing 411, so that it is difficult to stabilize the egg.

(First embodiment)

1 is a front view of a refrigerator according to a first embodiment of the present invention, FIG. 2 is a front cross-sectional view of the refrigerator of FIG. 1, and FIG. 3 is a perspective view showing a state in which the door of the refrigerator of FIG. 1 is opened, and FIG. Figure is a partial perspective view of the refrigerator compartment of the refrigerator of Figure 1.

As shown in FIGS. 1 to 4, the refrigerator 100 includes an outer case 101, an inner box 102, a heat insulating box 110, and a heat insulating door body 111. The heat insulating box 110 is filled with a heat insulating material 103 such as a foamed rigid polyurethane foam. The heat insulating door body 111 can be opened and closed. A storage compartment is provided inside the refrigerator 100. The storage compartment is provided with a refrigerating compartment 112 of the first storage compartment, an ice making compartment 113 and an upper freezing compartment 114 of the second storage compartment arranged side by side, and a freezing compartment 115 is provided below, and a vegetable compartment is provided in the lowermost compartment. 116.

Each storage room has been partitioned into rooms of different temperature zones by means of heat insulation panels 120. The storage compartments of the same degree in the temperature domain are separated by a structural partition 121 to allow air and heat to enter and exit freely.

Further, the heat insulating door body 111 provided in the opening of each storage room can be opened and closed in the left-right direction in the refrigerator compartment 112, that is, the so-called French heat insulating door body 111a is provided on the left and right sides.

Further, the ice making compartment 113, the upper freezing compartment 114, the freezing compartment 115, and the vegetable compartment 116 are each provided with a drawer type heat insulating door body 111b. Next, an ice making box 113a, an upper freezing box 114a, a plurality of freezing boxes 115a, and a plurality of fruit and vegetable boxes 116a are provided inside. When each of the heat insulating door bodies 111b is pulled out, the respective casings are pulled out at the same time, and the food is easily placed and taken out inside.

The refrigerating compartment 112 is provided with a gantry 123 inside the box of the heat insulating door body 111a, and can accommodate drinks, bottles, and the like. Further, the refrigerating chamber 112 is provided with a plurality of inner racks 124 therein, and the lowermost layer serves as an in-tank housing space 125. From the right side, a large refrigerating box 130 that can be rubbed back and forth is provided in order, and the upper and lower layers are formed. The box 131 and the lower case 132 and the water supply tank 133 for automatic ice making. Each of the casings is provided with a wall surface and can be independently provided in a slightly closed structure during storage. The boundary between the refrigerating box 130, the upper box 131 and the lower box 132 is the same as the left and right borders of the French heat insulating door 111a, and the opening and removal of any box can be performed by opening the single box door.

Further, the in-tank housing space 125 at the bottom of the inside of the refrigerating compartment 112 (first storage compartment) is located above the heat insulating panel 120. Part of the in-tank storage space 125 is divided into a drawer type upper case 131 and a lower case 132, and is not a space for forcibly introducing cold air.

The egg storage box of the upper case 131 is provided with a detachable egg rack (not shown). When the egg rack is stored and the egg box containing the egg is stored, the egg rack is placed on the upper case 131 by changing the front and back of the egg rack.

The upper case 131 can accommodate two rows of eggs in the depth direction, and can accommodate at least 10 or more, and 14 are more preferable. When 14 eggs can be stored, even if there are 4 eggs left in the egg storage box, it is possible to store 10 egg boxes.

According to the statistics page of the Japan Chicken Association of the corporate judicial person, the household survey of the Ministry of Internal Affairs and Communications of Japan is cited, and the daily usage of eggs per person is listed by year. From above, the Japanese daily usage of eggs per person in 2007 was 27.2g. If the average weight of the eggs is about 60 g, it is known that about 1/2 is used. However, the use of 1/2 eggs and the remaining 1/2 use form is very abnormal. Therefore, it is more reasonable to use one on average for 2 days.

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

The average family member of the large refrigerator purchases is 4 people, and the minimum number of eggs required for the refrigerator is 10, but at this time, the new egg box cannot be stored unless the eggs are all used up. Moreover, when 12 eggs can be stored, new eggs can be stored when there are two eggs left, but it is statistically observed that the average usage of four family members is four, and two may not be enough.

Therefore, the design of 10 packages and the storage of 4 or more upper boxes 131 allows the user to effectively develop the egg purchase cycle, while maintaining the purchase of fresh eggs for consumption. In other words, when the user is a family of four, the newly purchased 10 eggs can be stored in the upper case 131 while maintaining the use of one egg for each of the family members, so that the convenience of the user can be improved.

Further, since there are two rows of holding portions arranged in two rows, the old eggs and the newly purchased new eggs can be easily managed separately. Further, the remaining eggs are placed on the front side in the front-rear direction, and the new egg box is housed inside, so that the old eggs can be taken in order without being mistaken. Therefore, unnecessary waste of food can be avoided and the convenience of the user can be improved. Further, since the upper case 131 can be stored in the preparation for containing the eggs, it is not necessary to use a space for the egg box or the like at two places.

Further, the lower case 132 is the same width (left-right direction) as the upper case 131, but its height is set lower than the size of the upper case 131. Thereby, the upper case 131 and the lower case 132 are not misplaced. That is, it is possible to avoid storing the egg storage case in the lower temperature lower layer case 132, and freezing the egg by mistake. In particular, the casing can be detachably loaded and unloaded for overall cleaning, and misplacement after cleaning can be avoided. Further, the user can be made aware of the difference in the use of the case, and the content of each case can be clearly discriminated, so that the user's convenience of use can be improved. Specifically, it can be determined that the egg is stored by the upper layer case 131 having a higher height, so that the user will not be mistaken when taking it.

The upper case 131 sets the height of the accommodating egg and the egg box to 7 cm or more, and the lower case 132 sets the storage height which can prevent the misplaced egg from being set to 6 cm. The height of the egg is about 6 cm, but the distance between the bottom of the egg and the bottom of the egg rack is about 0.5 cm, so the size of 6 cm cannot be accommodated.

In addition to fresh products such as fish and meat, the refrigerated box 130 can store processed food such as ham and Vienna sausage, aquatic fish paste products such as bamboo wheels and fish plates, frozen foods such as noodles and side dishes, and various foods such as yogurt. The shape also ranges from bagged to plated and varies in size.

The refrigerating case 130 for accommodating the above-mentioned various kinds of foods, in particular, the small item storage items are often blocked by other foods, and the state of the storage period is expired and must be discarded. As in the present embodiment, a plurality of storage boxes for refrigerating, such as a larger refrigerating box 130 and a lower box 132, are disposed. Next, the lower casing 132 is formed into a shape suitable for a thin small object, and the large object is placed in the refrigerating box 130, and the small object is placed in the lower casing 132. As a result, it is possible to distinguish between storing large objects and small objects, and it is easy to manage small foods. Therefore, the wasteful waste of small foods can be reduced.

There is a large temperature variation in the vicinity of the heat insulating panel 120 that partitions the components of the refrigerating compartment 112, the ice making compartment 113, and the upper freezing compartment 114. However, in the present embodiment, the upper cassette 132 of the egg storage case is disposed on the lower casing 132. In other words, the egg storage case is not disposed directly above the heat insulating plate 120, but is sandwiched between the upper case 132 and the upper case 131 of the egg storage case. Therefore, the temperature variation in the upper casing 131 can be reduced, and the temperature variation of the egg itself can be further reduced to maintain the quality of the egg.

The depth of the inner frame 124 is different from the opening of the refrigerating chamber 112 to the inside and the left and right sides, and the depth of the left side is longer than the depth of the right side. The box inner frame 124 has been set to a depth to avoid conflict with the gantry 123.

Moreover, each of the casings of the in-tank housing space 125 disposed in the lowermost layer in the refrigerating compartment 112 corresponds to the shape of the inner frame 124. That is, the individual depth dimensions of the left and right boxes are different.

Specifically, the depth of the refrigerating case 130 is small, and the upper and lower layers of the upper layer case 131 and the lower layer case 132 are compared with the refrigerating case 130, and the depth setting is large.

Thereby, the upper case 131 of the egg storage box can ensure a long depth dimension, and can accommodate two rows of eggs, and can accommodate more than 14 pieces, thereby improving the convenience of use. Further, since the small contents of the lower case 132 can be refrigerated and stored in the depth direction, the small objects can be prevented from being overlapped and the capacity can be increased.

Further, although the upper case 131 is different from the egg rack, it may be a case body of the one shown below.

Fig. 5 is a perspective view showing a body type egg storage case of a refrigerator according to a first embodiment of the present invention. 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 sliding portion 144.

The plate portion 141 is a member that extends in the horizontal plane in the integrated egg storage case 140.

The holding portion 142 is provided with a plurality of members on the plate-like portion 141, and is formed as a bulging depression below the plate-like portion 141. Further, the holding portion 142 can be formed integrally with the plate portion 141.

The wall portion 143 is a member that is integrally provided with the plate portion 141 and extends in the vertical direction around the periphery of the plate portion 141. That is, the wall portion 143 and the plate portion 141 are integrally formed.

The sliding portion 144 is a member that is integrally provided with the wall portion 143 at the lower end of the left and right wall portions 143 and that extends in the depth direction. Further, the sliding portion 144 is a member that can suppress vibration and pull the integrated egg storage case 140 in the depth direction.

As described above, in the integrated egg storage case 140, the wall portion 143 and the plate portion 141 are integrally formed. That is, since the storage box and the egg rack are integrally formed, the egg rack does not move in the storage box, and the egg can be stably held. Moreover, the storage box and the egg rack can be integrally formed, and the manufacturing cost is reduced.

Moreover, since the egg is accommodated in the space partitioned by the plate-like portion 141 and the wall portion 143, it is possible to prevent the bacteria or the like adhering to the eggshell from adhering to other foods. Moreover, when the egg flies out from the holding portion 142 due to vibration or the like at the time of pulling out, it is possible to prevent the egg from falling outside the integrated egg storage case 140. Further, when the egg is broken in the integrated egg storage case 140, the egg liquid can be prevented from flowing out of the integrated egg storage case 140.

Further, the body type egg storage case 140 of the present embodiment includes a sliding portion 144 provided at the lower end of the left and right wall portions 143. However, the integrated egg storage case 140 may have a convex sliding portion extending in the depth direction outside the middle position in the height direction of the left and right wall portions 143. That is, it is configured such that the integrated egg storage case 140 can be pulled out in the depth direction. Moreover, if the vibration of one of the body type egg storage cases 140 at the time of pulling out can be suppressed, the integrated egg storage case 140 can be provided with any sliding part.

Further, from the front side, the water supply tank 133 for automatic ice making is disposed to the left of one of the spaces on the side of the upper casing 131, and the large refrigerating box 130 is disposed to the right of the other space on the side. The water in the water supply tank 133 has a large heat capacity, so that the influence of heat conduction from the inner tank can be reduced. Moreover, the air-insulation by the refrigerating box 130 can prevent the temperature of the egg storage box from being lowered and the temperature variation can be reduced. In other words, the water supply tank 133 and the refrigerating box 130 surround the left and right direction of the egg storage case, and the temperature of the egg storage case can be prevented from being lowered, and the temperature fluctuation can be reduced.

In the refrigerator of the above structure, the temperature setting of each chamber is set such that the refrigerating temperature of the refrigerating chamber 112 is 2 ° C ~ 5 ° C, the refrigerating box 130 in the refrigerator is 0 ° C ~ 1 ° C, and the upper box 131 is 2 ° C ~ 5 °C, the lower case 132 is 0 ° C ~ 1 ° C. Further, the lower ice making compartment 113, the upper freezing compartment 114, and the freezing compartment 115 are set at about -20 ° C of the freezing temperature. The fruit and vegetable compartment 116 is set at a temperature slightly higher than the temperature of the refrigerating compartment 112, and is 4 ° C to 7 ° C.

In addition, the refrigerating box requires the accuracy of temperature management in the nature of the storable storage item. Since the refrigerating box of the lower case 132 has a thin shape, the possibility that the foods in the refrigerating case are overlapped and stored in the refrigerating case is low, and the temperature management of the food in the refrigerating case can be performed with higher precision.

Each chamber is temperature-controlled by a cooling system (not shown), a cooling duct (not shown), and a control mechanism (not shown). The cooling of the refrigerating compartment 112 is based on the detected temperature of a temperature sensor (not shown) provided in the refrigerating compartment 112, and the amount of cold air distribution to the refrigerating compartment 112 is adjusted by an air brake (not shown).

The refrigerating box 130 and the lower box 132 will be affected by heat conduction from the freezing chamber 113 and the upper freezing chamber 114 of the freezing temperature. Moreover, since the heater used in the prior art is not used, the surface temperature of the heat shield 120 is low. Therefore, the refrigerating box 130 and the lower casing 132 do not need to use a complicated cooling duct structure and the duct control device, and the inside of the refrigerating chamber 112 can be lowered in temperature.

Further, the upper casing 131 is air-insulated by the lower casing 132, so that the temperature of the egg storage box can be prevented from being lowered without using a heater. Therefore, the power consumption of the heater can be suppressed, and the heat shield is not required to be designed to be thick, so that the internal volume of the tank is not reduced. Secondly, it can prevent the egg from freezing and maintain the quality of stability, and can save energy and provide a refrigerator with a large internal content and easy to use.

That is, since the lower casing 132 has no heating mechanism (heater), it is a refrigerator which can maintain a low temperature as compared with the upper casing 131. The upper case 131 is an egg storage case which can be maintained at 0 ° C or higher without a heating mechanism (heater).

Further, in the present embodiment, the lower case 132 is a refrigerated case of 0 to 1 ° C, but in the gist of the present invention, the lower case 132 only needs to be set to be lower than the upper case 131. The lower case 132 is not necessarily set in the temperature range of refrigerating, and the lower case 132 can also be set in a temperature range such as 0 to 3 °C.

In addition, when the space of the refrigerator is arranged in the refrigerator, the storage space in the box is close to the freezing temperature, and the same effect can be obtained even in other space configurations. For example, the lower part of the refrigerator may be a freezer compartment that is not separated into an ice making compartment and an upper freezing compartment.

Further, even if the upper case 131 and the lower case 132 are separated into a structure that approaches the width of the refrigerator, the same effect can be obtained.

Further, in the first embodiment of the present invention, the upper casing 131 can be placed in an egg storage box. However, the upper case 131 can also be used as a food storage case such as tofu which can be placed in a state where the quality is greatly reduced once it is frozen.

A compressor (not shown) provided in the lower portion of the main body of the refrigerator 151 can drive the cooler, and the air (cold air) cooled by the cooler is sent to each storage compartment. Further, cooling control is individually performed for each storage compartment to reach a predetermined temperature.

Fig. 7 is a perspective view showing a state in which the door of the refrigerator of the second embodiment of the present invention is opened. The opening of the refrigerator compartment 153 is provided with a left door 160a and a right door 160b as described above. The left door 160a is provided with a plurality of left gantry 190 in the vertical direction on the side of the refrigerating compartment 153, and the right door gantry 160b is also provided with a plurality of right gantry 191. In the gantry of the plurality of door doors, a storage space including a plurality of layers is formed in the refrigerating chamber 153.

Next, the above-mentioned plurality of gantry is mainly used for separately storing bottle bottles such as beverage bottles and seasonings such as beverages. Therefore, the door frame is provided with a wall portion on the left and right sides, and the upper portion has an open shape. Further, the right gantry 191 protrudes toward the storage compartment side from the left gantry 190 to constitute a larger storage space.

Further, the refrigerator compartment 153 is provided with a plurality of shelf plates 180 for arranging foods and the like in a bridge shape from the left side surface to the right side surface. The plurality of shelf plates 180 form a storage space including a plurality of layers in the refrigerator compartment 153.

Further, a plurality of drawers are disposed in the lowermost layer of the storage space of the refrigerating compartment 153. Specifically, a refrigerating box 182 suitable for storing refrigerated foods such as raw noodles, aquatic fish products, and side dishes, a small box 183 suitable for storing small items such as seasonings in bags, and egg storage suitable for storing eggs are disposed. Box 200. These drawers can be pulled separately.

Further, in the refrigerator 151 according to the second embodiment of the present invention, the egg storage case 200 is provided in the lower layer, and the small box 183 is provided on the upper layer. However, the egg storage case 200 may be provided on the upper layer, and the small box 183 may be placed on the lower layer. .

Fig. 8 is a partial perspective view showing the refrigerator compartment of the refrigerator in the second embodiment of the present invention. The depth dimension of the shelf 180 is different from the opening of the refrigerating compartment 153 inwardly and left and right. The depth dimension of the left side of the shelf 180 is longer than the depth dimension of the right side. The depth dimension of the shelf 180 does not cause the left gantry 190 and the right gantry 191 to collide. Moreover, the depth dimension of the shelf 180 corresponds to the shape of the left gantry 190 and the right gantry 191.

In addition, in the shelf 180, the left side portion of the shelf 180 including the longer portion of the depth dimension is the large shelf portion 180a, and the right portion of the shelf 180 including the shorter portion of the depth dimension is the small shelf portion 180b. .

Moreover, the left and right drawers disposed in the lowermost layer of the storage space in the refrigerating compartment 153 correspond to the shape of the shelf plate 180. That is, the depth dimensions of the left and right drawers are different.

Specifically, the drawer and the shelf 180 are of a depth dimension that does not cause the left gantry 190 and the right gantry 191 to collide. Next, it corresponds to the depth dimension of the shape of the left gantry 190 and the right gantry 191.

That is, the depth of the small box 183 and the egg storage case 200 provided above or below the large shelf portion 180a on the left side is substantially the same as that of the large shelf portion 180a. Further, the depth of the refrigerating box 182 provided at the position corresponding to the right side plate portion 180b is substantially the same as that of the small frame portion 180b.

For example, when the depth dimension of the egg storage box 200 that requires a longer depth is the same as the depth dimension of the refrigerated box 182, the amount of protrusion of the left and right gantry must be reduced to avoid conflict between the egg storage box 200 and the refrigerating box 182. . Therefore, if the above-described refrigerator does not increase the depth of the entire refrigerator, it is impossible to secure a sufficient storage space for the gantry.

Further, when the refrigerator 151 of the present embodiment has the depth dimension of the refrigerating container 182 smaller than the depth dimension of the egg storage case 200, the amount of protrusion of the right gantry 191 can be increased. That is, the refrigerator 151 can secure the storage space of the right gantry 191 and can secure the depth dimension of the egg storage box 200.

As described above, when the large shelf portion 180a having a large depth dimension is disposed above or below the egg storage case 200, the egg storage case 200, the refrigerating case 182, and the left gantry 190 can be secured without changing the size of the entire refrigerator 151. And the storage space required for the right door frame 191.

Further, the drawer is not necessarily required to be disposed in the space below the lowermost shelf 180, and may be disposed in the space of the refrigerator compartment 153 which is separated from any of the plurality of shelf plates 180. That is, the drawer may be disposed in a space formed above or at the bottom surface of the shelf 180 included in the refrigerating compartment 153 and the inner compartment 170 of the refrigerating compartment 153.

Hereinafter, the egg storage case 200 will be described in detail.

Fig. 9 is a perspective view showing an egg storage case included in the refrigerator in the second embodiment of the present invention. The x-axis represents the depth direction of the refrigerator 151, and the y-axis represents the left-right direction, and the z-axis represents the height direction. In addition, the same applies to the following illustrations.

The egg storage case 200 includes a plate portion 201, a holding portion 202, a wall portion 203, and a sliding portion 204.

The plate portion 201 is a member that extends in the horizontal direction in the egg storage case 200.

The holding portion 202 is provided with a plurality of members in the plate-like portion 201, and is formed as a member which is inflated and recessed toward the lower portion of the plate-like portion 201. Further, the holding portion 202 can be formed integrally with the plate portion 201. The plurality of holding units 202 will be described later with reference to the drawings of Figs. 10, 11, 12A, and 12B.

The wall portion 203 is integrally provided with the plate portion 201, and is a member that extends in the vertical direction around the periphery of the plate portion 201. That is, the wall portion 203 and the plate portion 201 are integrally formed.

The sliding portion 204 is integrally provided with the wall portion 203 at the lower end of the left and right wall portions 203, and is a member that extends in the depth direction (x-axis direction). Further, the sliding portion 204 is a member that can suppress the vibration and pull the egg storage case 200 in the depth direction.

As described above, in the egg storage case 200, the wall portion 203 and the plate portion 201 are integrally formed. That is, since the storage box and the egg rack are integrally formed, the egg rack does not move in the storage box, and the egg can be stably held. Moreover, the storage box and the egg rack can be integrally formed, and the manufacturing cost is reduced.

Moreover, since the egg is accommodated in the space in which the plate-shaped portion 201 and the wall portion 203 are separated, it is possible to suppress the adhesion of bacteria and the like adhering to the eggshell to other foods. Moreover, when the egg flies out from the holding portion 202 due to vibration or the like at the time of pulling out, it is possible to prevent the egg from falling outside the egg storage case 200. Further, when the egg is broken in the egg storage case 200, the egg liquid can be prevented from flowing out of the egg storage case 200.

Also, for sanitation, the storage box and the egg rack will be cleaned frequently. The conventional structure allows the user to clean the storage box and the egg rack, or remove the egg rack and change the back of the watch to use it. In this way, the use of the egg rack is relatively high, and the egg rack will often be removed from the storage box, so the egg rack may be lost. However, in the present embodiment, the wall portion 203 of the egg storage case 200 is integrally formed with the plate portion 201. That is, since the storage box and the egg rack are integrally formed, the egg rack is not lost.

Further, the egg storage case 200 of the present embodiment includes a sliding portion 204 provided at the lower end of the left and right wall portions 203. However, a convex sliding portion extending in the depth direction may be provided outside the intermediate position of the left and right wall portions 203 in the height direction. That is, if the egg storage case 200 can be pulled out in the depth direction, and the vibration of the egg storage case 200 at the time of pulling out can be suppressed, the egg storage case 200 can be provided with any sliding portion.

Fig. 10 is a top view of an egg storage case included in the refrigerator according to the second embodiment of the present invention, and Fig. 11 is a cross-sectional view taken along line A-A of Fig. 10. As shown in Fig. 10, the plate-like portion 201 is provided with two rows of holding portions in which seven holding portions 202 are arranged in the drawing direction (y-axis direction) in the direction (x-axis direction) in which the drawing direction is staggered.

As described above, the egg storage case 200 can accommodate 14 eggs. Therefore, when four eggs are stored in the egg storage case, 10 eggs can be stored.

Further, as shown in Fig. 8, the large shelf portion 180a having a large depth dimension of the shelf 180 is disposed at a position corresponding to the installation position of the egg storage case 200. Therefore, the storage space required for the gantry can be ensured, and the egg storage case 200 can be provided with two rows of holding portions arranged in the depth direction without arranging the size of the entire refrigerator.

Further, as shown in Fig. 9, the egg storage case 200 is composed of an integral part, so that there is no need for an activity space for taking out the egg rack from the storage case. In other words, since the egg storage space can be increased, it is possible to provide two rows of holding portions arranged in the depth direction without changing the size of the entire refrigerator.

Further, as shown in FIGS. 10 and 11, the holding portion 202 includes a main opening portion 202a and a sub-opening portion 202b. The main opening portion 202a is located on the plate surface of the plate portion 201.

The sub-opening portion 202b is located at the bottom of the holding portion 202, and the diameter of the sub-opening portion 202b is smaller than the diameter of the main opening portion 202a. Further, the sub-opening portion 202b is continuously in contact with the main opening portion 202a with a smooth curved surface. Further, the sub-opening portion 202b is continuously in contact with the bottom surface of the holding portion 202 with a smooth curved surface.

Then, the curved surface connecting the main opening 202a and the sub-opening 202b and the curved surface of the connecting sub-opening 202b and the bottom surface are successively in contact with each other in the sub-opening portion 202b.

12A is a cross-sectional view showing a holding portion when a large egg is stored in an egg storage case included in the refrigerator according to the second embodiment of the present invention, and FIG. 12B is a view showing a smaller egg contained in the egg storage case included in the refrigerator. A cross-sectional view of the holding portion of the time.

As shown in Fig. 12A, the larger egg 301 is mainly supported by the main opening portion 202a and a smooth curved surface connecting the main opening portion 202a and the sub-opening portion 202b. Secondly, the size of the egg is somewhat different, and even if it is not in conformity with the curved surface, the larger egg can still maintain the surface of the egg by the main opening portion 202a.

Further, as shown in Fig. 12B, the smaller egg 302 mainly holds the surface curved surface of the egg by the sub-opening portion 202b. At this time, the bottom surface is set to a size that does not abut against the tip end portion of the egg, and it is possible to avoid a situation in which the sub-opening portion 202b abuts against the bottom surface before the egg is held.

As described above, since the holding portion 202 includes the main opening portion 202a and the sub-opening portion 202b having different diameters, it is possible to stably hold eggs of different sizes. Specifically, the holding portion 202 can stably hold eggs of a plurality of sizes such as S (Small), M (Medium), and L (Large).

Further, the holding portion 202 is formed integrally with the plate-like portion 201 by a plurality of members having a plurality of plate-like portions 201 and recessed toward the lower side of the plate-like portion 201. Therefore, compared with the case where the plate-shaped portion shown in Patent Document 2 is flat, the twist strength can be improved. Therefore, the rigidity at the time of pulling out the egg storage case can be improved, and the deformation of the egg storage case can be avoided even when the egg storage case is pulled out with a brute force.

Figure 13 is a cross-sectional view showing an egg storage box in which an egg box is housed in a refrigerator according to a second embodiment of the present invention. The holding portion 202 is disposed at a position where the lower protruding portion 303b of the egg box 303 can be stored. Further, the main opening portion 202a has a diameter that can accommodate the lower protruding portion 303b of the egg carton 303.

Further, the egg storage case 200 has a storage space for storing the height of the egg cassette 303 attached.

As described above, the egg storage case 200 can stably hold the egg box 303 in addition to the egg itself.

Further, as shown in FIGS. 12A and 12B, the holding portion 202 includes the sub-opening portion 202b. Therefore, even if the diameter of the main opening portion 202a is such that the size of the egg box 303 can be maintained, a small egg such as an S size can be stably maintained.

As described above, according to the present embodiment, the pullable egg storage case 200 can be integrally formed, so that the manufacturing cost can be reduced. Further, the egg rack is not moved inside the egg storage case 200, so that the egg can be kept in stability.

Further, since the holding portion 202 includes two openings having different diameters, the egg storage case 200 can stably hold a plurality of eggs and egg cartons having different sizes.

Moreover, since it is preferable to store eggs in an environment of 10 ° C or less, it is often stored in a refrigerator. However, when an egg box egg is used up in a short period of time, there is a case in the winter or in the cold zone where the egg is not necessarily stored in the refrigerator. At this time, the egg box is placed directly on the kitchen counter or dining table.

When the egg is placed in the egg storage box 200, and the egg storage box 200 is placed on a kitchen counter or a dining table or the like, the wall portion of the egg storage box 200 can protect the egg. Therefore, even if the dish or the human hand accidentally collides with the egg, the egg can be prevented from rupturing.

Further, in addition to beautifying the appearance, it is possible to establish a new form in which the eggs are placed in the egg storage box 200 and placed on a kitchen counter or dining table.

Further, since the holding portion 202 includes a diameter smaller than the diameter of the opening formed on the plate surface of the plate portion 201 and is provided in the sub-opening portion 202b at the bottom of the holding portion 202, the holding portion 202 has openings having different diameters. That is, the larger-sized egg is mainly held by the large-diameter main opening portion 202a, and the smaller-sized egg is mainly held by the small-diameter auxiliary opening portion 202b. That is, it is possible to maintain a plurality of eggs in a more stable manner.

Further, since the small egg can be held by the sub-opening portion 202b, the diameter of the opening portion can be enlarged until the egg box can be held. Therefore, when the egg box is housed in the egg storage case 200, it is not necessary to change the front and back of the egg rack, and the convenience of the user can be improved.

Further, since the plate-like portion 201 is provided with the holding portion rows in which the seven holding portions 202 are arranged in two rows, the egg storage case 200 can accommodate 14 eggs. Therefore, when four eggs are stored in the egg storage case 200, ten eggs can be accommodated. Further, since the egg storage case 200 is provided with seven rows of holding portions arranged in two rows, the old eggs and the newly purchased new eggs can be easily managed separately. That is, the convenience of the user can be improved.

Hereinafter, other egg storage boxes will be described.

Fig. 14 is a cross-sectional view showing another egg storage case included in the refrigerator according to the second embodiment of the present invention, and Fig. 15 is a cross-sectional view taken along line B-B of Fig. 14.

Next, the lower end (L) of the sliding portion 204 is located higher than the lower end (M) of the holding portion 202.

Therefore, the wiping agent is applied to the lower end (M) of the sliding portion 204 of the egg storage case 220 in order to improve the wiping property. However, when the egg storage case 220 is placed on a flat table or the like, the lower end (L) of the sliding portion 204 as the wiping portion is separated from the installation surface. Therefore, the wiping agent applied to the lower end (L) of the sliding portion 204 does not adhere to the setting surface, and the table top is not stained by the wiping portion.

Moreover, if the lower end (L) of the sliding portion 204 is located lower than the lower end (M) of the holding portion 202, the space formed by the holding portion 202 and the sliding portion 204 will be difficult to reach, and the egg storage box is not easily cleaned. 220.

However, as shown in Fig. 15, if the lower end (L) of the sliding portion 204 is located higher than the lower end (M) of the holding portion 202, the space formed by the holding portion 202 and the sliding portion 204 can be easily reached. In the dotted line A) of Figure 15. Therefore, the dirt adhering to the sliding portion 204 and the holding portion 202 in the vicinity of the extremely narrow space can be easily wiped off, and the cleanliness of the egg storage case 220 can be improved.

Further, the height of the lower end (N) of the front wall portion 203 is substantially the same as the lower end (M) of the holding portion 202. Therefore, when the egg storage case is viewed from the front, the holding portion 202 is not directly seen, and the appearance can be improved.

(Third embodiment)

Hereinafter, a refrigerator according to a third embodiment of the present invention will be described with reference to the drawings. In the third embodiment of the present invention, the differences from the second embodiment will be described, and the same components as those of the refrigerator according to the second embodiment will be denoted by the same reference numerals and will not be described.

In this way, the egg storage box 400 can store 18 eggs.

As described above, in the egg storage case 400, the wall portion 203 and the plate portion 201 are integrally formed. That is, since the storage box and the egg rack are integrally formed, when the right door 160b having a high switching frequency is opened and closed, the egg rack does not move in the storage box. Therefore, the egg can be kept stable, and since the egg frame does not move, noise can be avoided and the quality of the egg can be prevented from being lowered. Moreover, the storage box and the egg rack can be integrally formed, and the manufacturing cost is reduced.

Further, in the present embodiment, the egg storage case 400 is provided in the center layer of the right door 160b of the refrigerating compartment, but the egg storage case 400 may be provided to the left case door 160a as needed. Further, it may be provided in the uppermost layer or the lowermost layer, but in terms of convenience of use, the egg storage case 400 is preferably provided in the center layer or the lowermost layer.

Further, in the present embodiment, the egg storage case 400 is provided with three rows of holding portions arranged in three rows in the front-rear direction (Q direction) of the refrigerator in the left-right direction (P direction) of the refrigerator. However, as needed, four, five or seven are arranged in the left-right direction (P direction) of the refrigerator, and two columns are arranged in the front and rear directions (Q direction) of the refrigerator.

Further, although the refrigerator of the present embodiment has the refrigerator of the left and right split type door shown in the second embodiment, the egg storage case 400 may be provided for the side open type refrigerator having one box door. At this time, the length of the door door in the left-right direction will increase, so that the number of the holding portion rows in the left-right direction of the refrigerator can be increased.
