Summary of Invention

Problems to be Solved by the Invention

[0006] As described above, the multi-tiered holder mainly comprises a holder body, a main column member, and a cap member. Users of the refrigerator assemble the multi-tiered holder in the refrigerator compartment according to the number of eggs purchased, and store and keep the eggs cool.

[0007] However, the multi-tiered holder described above is assembled from multiple parts. Therefore, the user needs to store the parts of the holder, prepare the necessary parts each time, and assemble it. On the other hand, when eggs are used in cooking and the number of eggs decreases, the user needs to take out the unnecessary parts of the holder from the refrigerator and store them. In short, the assembly, disassembly, and storage of the various parts of the multi-tiered holder present a challenge for the user, as it is time-consuming.

[0008] Furthermore, the multi-tiered holder described above has a structure in which the main column member is assembled to the upper surface of the legs of the holder body. As a result, increasing the number of tiers in the multi-tiered holder tends to make the overall structure larger. In addition, the storage area of ​​the door pocket on the insulated door side of the refrigerator compartment is narrow, and there is a problem in that the multi-tiered holder described above is difficult to install in the door pocket.

[0009] The present invention has been made in view of the above circumstances, and aims to provide a refrigerator equipped with a movable egg storage mechanism, which allows for efficient use of the storage space in the door pocket by deploying the mounting plate of the movable egg storage mechanism when storing a large number of eggs. [Means for solving the problem]

[0010] The refrigerator of the present invention comprises an insulated box body in which a storage compartment is formed, an insulated door attached to the insulated box body that can open and close the front opening of the storage compartment, a storage case disposed on the insulated door, and a movable egg storage mechanism disposed on the storage case, wherein the movable egg storage mechanism has a mounting plate on which a plurality of eggs can be placed, a shaft portion disposed on the mounting plate, a guide groove that movably supports the shaft portion, and a support portion that rotatably supports the mounting plate. The shaft portion comprises a main shaft connected to the mounting plate described above, and a first shaft and a second shaft formed at the tip of the main shaft, and the guide groove comprises a first groove through which the first shaft is guided, and a second groove continuous with the first groove through which the second shaft is guided.The mounting plate is stored upright inside the storage case when not in use, and is unfolded horizontally to the bottom of the storage case when in use. The mounting plate has an inclined state at a predetermined angle with respect to the bottom surface while transitioning from the upright state to the horizontal state, and while the mounting plate is transitioning from the upright state to the inclined state, the first shaft and the second shaft slide in relation to the first groove and the second groove, respectively, and while the mounting plate is transitioning from the inclined state to the horizontal state, the first shaft slides in relation to the first groove, and the second shaft rotates inside the second groove. It is characterized by the following:

[0014] Furthermore, the refrigerator of the present invention is characterized in that a plurality of recesses for placing eggs are formed on the bottom surface. [Effects of the Invention]

[0015] In the refrigerator of this invention, a storage case is installed in the door pocket of the insulated door, and a movable egg storage mechanism is installed inside the storage case. The mounting plate of the movable egg storage mechanism is deployed horizontally when in use, so that the storage case can be used as a two-tiered egg storage area. With this structure, even if the user of the refrigerator purchases a large number of eggs at once to suit their lifestyle, they can be stored and kept cool in the storage case. On the other hand, when the number of eggs to be kept cool decreases as the user uses some of the eggs, the mounting plate is stored upright, so that the storage case can be used effectively.

[0016] Furthermore, in the refrigerator of the present invention, a first shaft and a second shaft are formed in the shaft portion that rotates the mounting plate. With this structure, the mounting plate can rotate between a horizontal position and an upright position relative to the bottom surface of the storage case.

[0017] Furthermore, in the refrigerator of the present invention, as the mounting plate transitions from an upright state to an inclined state, the first axis and the second axis slide relative to the first groove and the second groove, respectively. This structure allows the mounting plate to rotate while moving away from the back of the storage case towards the inside of the refrigerator. As a result, the rotation axis of the mounting plate shifts towards the inside of the storage case, increasing the depth of the mounting plate and thus increasing the storage capacity of eggs.

[0018] Further, in the refrigerator of the present invention, the rotation shaft of the mounting plate is positioned as far away from the back surface of the storage case toward the inner side of the compartment as possible, so that the depth width of the mounting plate is increased. In addition, the first shaft restricts the rotation amount of the mounting plate, and the horizontal state of the mounting plate is maintained. With this structure, the number of eggs stored in the storage case is increased, and the eggs are prevented from colliding with the mounting plate and being broken.

[0019] Further, in the refrigerator of the present invention, the storage case can be used as a two-story egg storage area according to the number of eggs to be stored. Brief Description of the Drawings

[Mode for Carrying Out the Invention]

[0021] Hereinafter, the refrigerator 10 of the present embodiment will be described in detail based on the drawings. In the following description, the vertical direction indicates the height direction of the refrigerator 10, the left-right direction indicates the width direction of the refrigerator 10 as viewed from the front, and the front-rear direction indicates the depth direction of the refrigerator 10. Further, in the description of the present embodiment, in principle, the same reference numerals are used for the same members, and repeated descriptions are omitted.

[0022] Figure 1 is a perspective view illustrating the external structure of the refrigerator 10 of the present embodiment as viewed from the front side. Figure 2 is a side cross-sectional view illustrating the structure of the refrigerator 10 of the present embodiment. Figure 3 is a perspective view illustrating the door pocket of the second heat insulating door 15 of the refrigerator 10 of the present embodiment.

[0023] As shown in Figure 1 and Figure 2, the refrigerator 10 includes a heat insulating box body 11 and a storage compartment formed inside the heat insulating box body 11. Further, as the storage compartments, a freezer compartment 12 and a refrigerator compartment 13 are formed from the upper side in the compartment. For convenience of explanation, the numbering of each storage compartment is shown in Figure 1.

[0024] The heat insulating box body 11 mainly has an outer box 21 made of a steel plate that forms the outer shape of the refrigerator 10, an inner box 22 made of a box-shaped synthetic resin plate formed inside the outer box 21, and a heat insulating material 23 disposed between the outer box 21 and the inner box 22. As the heat insulating material 23, for example, urethane foam is adopted.

[0025] The freezer compartment 12 is on the upper side inside the heat insulating box body 11, and is formed using approximately 1 / 3 of the interior of the compartment. The front opening of the freezer compartment 12 is closed by the first heat insulating door 14 so as to be openable and closable. The first heat insulating door 14 is a rotary door. The end side of the first heat insulating door 14 in the left-right direction on the paper surface is rotatably pivoted to the heat insulating box body 11.

[0026] The refrigerator compartment 13 is located in the lower part of the interior of the insulated box 11 and occupies approximately two-thirds of the interior space. The front opening of the refrigerator compartment 13 is closed by a second insulated door 15, which can be opened and closed. The second insulated door 15 is a rotating door. The left-right ends of the second insulated door 15 are pivotally supported on the insulated box 11. The refrigerator compartment 13 is divided into multiple sections in the vertical direction by partition plate members 16, for example.

[0027] A cooling chamber 24 is partitioned off behind the freezer chamber 12. A cooler 25 is installed in the cooling chamber 24. A machine room 26 is partitioned off at the bottom rear of the insulated box 11. A compressor 27 and other components are installed in the machine room 26. The cooler 25 and compressor 27 are connected to an expansion means and a condenser (not shown) via refrigerant piping, forming a vapor compression refrigeration cycle. The components of the vapor compression refrigeration cycle are interconnected via refrigerant piping (not shown).

[0028] When the above refrigeration cycle is in operation, the air inside the cooling chamber 24 is cooled by the cooler 25. A blower 28 is installed above the cooler 25 in the cooling chamber 24. The blower 28 is, for example, an axial flow blower or a centrifugal blower. The blower 28 blows the cold air inside the cooling chamber 24 toward the freezer chamber 12 and the refrigerator chamber 13. The cold air is then blown to each storage chamber via various air passages 19, 29, and 30, and through forced circulation, the freezer chamber 12 reaches the freezing temperature range and the refrigerator chamber 13 reaches the refrigeration temperature range. The air passage 30 communicates with the freezer chamber 12 at another cross-section, and the cold air circulates there as well.

[0029] A defrost heater 20 is positioned below the cooler 25 in the cooling chamber 24. As the refrigeration cycle operates, a thick layer of frost forms on the surface of the cooler 25. When this occurs, the control unit (not shown) stops the compressor 27 and energizes the defrost heater 20 to perform a defrosting operation, melting and removing the frost. The defrost heater 20 can be an electric resistance heater, a sheathed heater, or a hot gas defroster.

[0030] As shown in Figure 3, the second insulated door 15 mainly comprises an outer panel 31 that forms the decorative surface of the refrigerator 10, an inner panel 32 disposed on the inside of the outer panel 31, a gasket 33 attached to the inner panel 32 in a frame shape, and an insulating material (not shown) formed in the space between the outer panel 31 and the inner panel 32. The outer panel 31 is, for example, a steel plate. The inner panel 32 is, for example, a synthetic resin plate, formed by vacuum forming using a mold.

[0031] A protrusion 34 is formed on the inner panel 32 of the second insulated door 15, bulging inward. The protrusion 34 is located inside the gasket 33 and is formed around the outer edge of the second insulated door 15. In other words, the protrusion 34 is formed to surround the storage area of ​​the door pocket provided in the second insulated door 15.

[0032] Furthermore, the door pockets of the second insulated door 15 include, for example, a storage case 41 for storing eggs, storage cases 42 and 43 for storing seasonings, etc., and storage cases 44 and 45 for storing PET bottles, etc. As shown in the figure, multiple protrusions 34 and 35 are formed on the inner panel material 32 and are used as receiving parts for the above-mentioned storage cases 41 to 45.

[0033] Multiple recesses 46 are formed on the bottom surface 41A of the storage case 41 for stably arranging eggs. As will be described in detail later, a movable egg storage mechanism 51 is installed inside the storage case 41. When a user of the refrigerator 10 needs to keep a large number of eggs cool, they extend the mounting plate 52 of the movable egg storage mechanism 51 to the usable position. As a result, the storage case 41 is used as a two-tiered egg storage area.

[0034] Next, the structure, operation, and usage of the movable egg storage mechanism 51 will be explained using Figures 4 to 8.

[0035] Figure 4 is a perspective view illustrating the structure of the movable egg storage mechanism 51 of the refrigerator 10 of this embodiment, as seen from the front. Figure 5 is an exploded perspective view illustrating the movable egg storage mechanism 51 of the refrigerator 10 of this embodiment. Figure 6 is a perspective view illustrating the operating state of the movable egg storage mechanism 51 of the refrigerator 10 of this embodiment. Figures 7A to 7D are side views illustrating the rotational state of the movable egg storage mechanism 51 of the refrigerator 10 of this embodiment. Figure 8 is a cross-sectional view illustrating the usage state of the movable egg storage mechanism 51 of the refrigerator 10 of this embodiment. Note that in Figures 7A to 7D, for explanatory purposes, the guide groove 70 and shaft portion 53 of the support portion 54 are mainly shown.

[0036] As shown in Figure 4, the movable egg storage mechanism 51 mainly comprises a mounting plate 52 on which multiple eggs can be placed, a pair of shafts 53 (see Figure 5) disposed at both ends of the mounting plate 52, and a support part 54 that movably supports the shafts 53. The movable egg storage mechanism 51 is installed inside the storage case 41 (see Figure 3) of the second insulated door 15. As will be described in detail later, when keeping a large number of eggs cool, the mounting plate 52 is extended to a nearly horizontal position relative to the bottom surface 41A (see Figure 3) of the storage case 41, and the storage case 41 is used as a two-tiered egg storage area.

[0037] As shown in Figure 5, the mounting plate 52 has a plate-like portion 61 and a frame portion 62 formed along the outer peripheral edge of the plate-like portion 61. The plate-like portion 61 has a plurality of openings 61A for placing eggs. The frame portion 62 has a pair of insertion holes 62A for inserting and fixing the shaft portion 53. The frame portion 62 extends downward from the plate-like portion 61 and secures a storage area for eggs that are led out downward from the openings 61A. The mounting plate 52 is integrally molded from, for example, PS resin.

[0038] Next, the shaft portion 53 has a pair of main shafts 63 connected to the mounting plate 52, and a first shaft 64 and a second shaft 65 formed on one end of the main shafts 63. The pair of main shafts 63 are each inserted into the insertion holes 62A of the mounting plate 52. The other end of the main shafts 63 is fixed to the frame portion 62, and the mounting plate 52 rotates in conjunction with the shaft portion 53. In addition, the main shafts 63 are of the soft-down type with dampers. Therefore, when the mounting plate 52 transitions from an upright state to a horizontal state, it rotates smoothly, making it easy for the user to use.

[0039] Furthermore, the first shaft 64 and the second shaft 65 are formed in parallel, flanking the center of the main shaft 63. The first shaft 64 and the second shaft 65 are fitted onto the tip of the main shaft 63. Note that in Figure 5, for explanatory purposes, the first shaft 64 and the second shaft 65 are shown separately. As will be described in detail later, the first shaft 64, shown by the solid line, moves within the first groove 70A, and the second shaft 65, shown by the dashed line, moves within the second groove 70B. Also, the shaft portion 53 is not limited to cases where the main shaft 63 and the first shaft 64 and the second shaft 65 are formed as separate parts; for example, they may be integrally molded from PS resin.

[0040] Next, the support portion 54 is, for example, roughly U-shaped when viewed from above, and has side plates 66, 67, and 68. A base portion 69 is formed on the bottom surface of the side plates 66, 67, and 68. The support portion 54 is formed as a self-supporting structure and is erected on the bottom surface 41A (see Figure 3) of the storage case 41.

[0041] Furthermore, guide grooves 70 supporting the shaft portion 53 are formed in the side plates 66 and 67, respectively. The guide groove 70 has a first groove 70A into which the first shaft 64 is inserted and a second groove 70B into which the second shaft 65 is inserted. The first shaft 64 and the second shaft 65 move within the first groove 70A and the second groove 70B, respectively, and the second shaft 65 rotates within the second groove 70B. With this structure, the mounting plate 52 is unfolded horizontally in use and stored upright in the storage case 41 when not in use.

[0042] Furthermore, a mounting portion 71 is formed on the tip side of each of the side plates 66 and 67. In addition, a pair of protrusions 73 are formed on the side surface in the left-right direction of the paper on the frame portion 62 of the mounting plate 52. On the other hand, a pair of recesses 72 are formed on the side plates 66 and 67 of the support portion 54. When the mounting plate 52 is unfolded horizontally, the mounting portion 71 rests on the tip side of the mounting plate 52 and supports it from below. Furthermore, the pair of protrusions 73 are fitted into the pair of recesses 72. The mounting plate 52 is then supported at six points by the shaft portion 53, mounting portion 71, recesses 72 and protrusions 73, allowing it to be stably unfolded horizontally. The mounting plate 52 also becomes the storage area for eggs on the second floor inside the storage case 41. At this time, the mounting portion 71 rests on the frame portion 62 of the mounting plate 52, securing the storage area for eggs on the first floor. Furthermore, the eggs stored on the mounting plate 52 are prevented from colliding with the eggs stored in the recess 46. The support portion 54 is integrally molded from, for example, PS resin.

[0043] As shown in Figure 6, the shaft portion 53 is inserted into the guide groove 70, moves within the guide groove 70, and rotates within the guide groove 70. With this structure, the mounting plate 52 rotates in conjunction with the movement of the shaft portion 53 while being pivotally supported by the support portion 54.

[0044] The mounting plate 52 rotates 90 degrees relative to the bottom surface 41A of the storage case 41 (see Figure 3) to become upright. The upright position of the mounting plate 52 is the storage state when the movable egg storage mechanism 51 is not in use.

[0045] Furthermore, when the mounting plate 52 is not rotating, it is in a horizontal position relative to the bottom surface 41A of the storage case 41. The horizontal position of the mounting plate 52 is the operating state of the movable egg storage mechanism 51.

[0046] Furthermore, the movable egg storage mechanism 51 transitions from the use state to the storage state when the mounting plate 52 rotates from 0 degrees to 90 degrees relative to the bottom surface 41A of the storage case 41. As will be described in detail later, the rotation of the mounting plate 52 from 0 degrees to 50 degrees is performed by the second shaft 65 rotating within the second groove 70B and the first shaft 64 sliding within the first groove 70A. On the other hand, the rotation of the mounting plate 52 from 50 degrees to 90 degrees is performed by the first shaft 64 and the second shaft 65 sliding within the first groove 70A and the second groove 70B.

[0047] Furthermore, the mounting plate 52 rotates 50 degrees relative to the bottom surface 41A of the storage case 41, and the inclination state of the mounting plate 52 at that point corresponds to the inclination state at the predetermined angle described in the present invention.

[0048] Next, using Figures 7A to 7D, we will explain the operation of the mounting plate 52 when using the movable egg storage mechanism 51, specifically how it transitions from the upright position to the horizontal position. Note that the operation when storing the movable egg storage mechanism 51 is the reverse, and we will omit that explanation here.

[0049] Figure 7A shows the case where the rotation angle between the mounting plate 52 and the bottom surface 41A of the storage case 41 (see Figure 3) is 90 degrees. The side plate 66 of the support part 54 has a first groove 70A extending in the height direction of the support part 54 (up and down direction on the paper) and a second groove 70B extending in the depth direction of the support part 54 (front and back direction on the paper). The second groove 70B is formed continuously with the first groove 70A at the upper end of the first groove 70A.

[0050] As shown in the diagram, the first shaft 64 is inserted into the first groove 70A, and the second shaft 65 is inserted into the second groove 70B. When the mounting plate 52 is in an upright position, the first shaft 64 is located at the lower end of the first groove 70A, and the second shaft 65 is located at the boundary between the first groove 70A and the second groove 70B.

[0051] Here, the first groove 70A is formed by a continuous curve that curves toward the inside of the storage case 41 (towards the rear of the paper) and a curve that curves toward the outside of the storage case 41 (towards the front of the paper). On the other hand, the second groove 70B is formed by a curve that curves toward the upper side of the storage case 41.

[0052] When the movable egg storage mechanism 51 is stored, the mounting plate 52 is subjected to a tilting force towards the interior of the storage case 41 due to its own weight. However, the shape of the first groove 70A and the second groove 70B restricts the rotational movement of the first shaft 64 and the sliding movement of the second shaft 65. This structure prevents the mounting plate 52 from spontaneously tipping over and becoming horizontal due to vibrations of the second insulated door 15 or the like when the movable egg storage mechanism 51 is not in use.

[0053] Figure 7B shows the case where the rotation angle between the mounting plate 52 and the bottom surface 41A of the storage case 41 is 70 degrees. As described above, when the mounting plate 52 is stored, the mounting plate 52 maintains the upright position described above. Then, when the user pulls the mounting plate 52 diagonally upward toward the inside of the storage compartment from the upright position shown in Figure 7A, the mounting plate 52 transitions from the state in Figure 7A to the state in Figure 7B.

[0054] As shown by the arrows in Figure 7A, the user's operation of the mounting plate 52 guides the first shaft 64 into the first groove 70A, and it moves upward within the first groove 70A. Similarly, the second shaft 65 is guided into the second groove 70B, and it moves forward within the second groove 70B.

[0055] In this case, the mounting plate 52 does not rotate around the first shaft 64 and the second shaft 65 as axes of rotation, but rather rotates as the first shaft 64 and the second shaft 65 slide within the first groove 70A and the second groove 70B. And because the first groove 70A is curved toward the front of the storage case 41, the mounting plate 52 rotates toward the interior of the storage case 41 while moving away from the inner plate material 32 (see Figure 3), which is the back of the storage case 41.

[0056] Figure 7C shows the case where the rotation angle between the mounting plate 52 and the bottom surface 41A of the storage case 41 is 50 degrees. Continuing from the state shown in Figure 7B, the user pulls the mounting plate 52 diagonally upward towards the inside of the storage compartment, causing the mounting plate 52 to transition from the state shown in Figure 7B to the state shown in Figure 7C.

[0057] As indicated by arrows 76 and 77 in Figure 7B, the first shaft 64 and the second shaft 65 are guided by the first groove 70A and the second groove 70B, respectively, and slide within the first groove 70A and the second groove 70B. The mounting plate 52 then rotates toward the interior of the storage case 41, moving further away from the inner panel 32 (see Figure 3), which is the back of the storage case 41. In the state shown in Figure 7C, the second shaft 65 reaches the front end of the second groove 70B.

[0058] Figure 7D shows the case where the rotation angle between the mounting plate 52 and the bottom surface 41A of the storage case 41 is 0 degrees. From the state shown in Figure 7C, the user pulls the mounting plate 52 diagonally downward toward the inside of the oven, causing the mounting plate 52 to move from the state shown in Figure 7C to the state shown in Figure 7D. In other words, the mounting plate 52 becomes nearly horizontal with respect to the bottom surface 41A of the storage case 41, and the movable egg storage mechanism 51 is put into use. Then, as shown in Figure 8, the storage case 41 becomes a two-tiered egg storage area.

[0059] As indicated by arrow 78 in Figure 7C, the second shaft 65 rotates within the second groove 70B. Meanwhile, as indicated by arrow 79, the first shaft 64 is guided by the first groove 70A and slides within the first groove 70A. In other words, the mounting plate 52 rotates around the second shaft 65 as its axis of rotation at the end of the second groove 70B. The rotation of the second shaft 65 stops when the first shaft 64 reaches the upper end of the first groove 70A.

[0060] As described above, when the rotation angle is between 50 and 90 degrees, the mounting plate 52 rotates while moving forward from the inner plate 32, which is the back of the storage case 41. This structure allows the mounting plate 52's axis of rotation to move away from the inner plate 32, thereby maximizing its width in the depth direction. Furthermore, within the structural design limitations of the storage case 41, the wider mounting plate 52 increases the amount of eggs that can be stored.

[0061] On the other hand, when the movable egg storage mechanism 51 is not in use, the mounting plate 52 is moved to the edge of the inner plate material 32, resulting in the upright position described above. This structure allows the movable egg storage mechanism 51 to be installed inside the storage case 41, while minimizing the reduction in the storage volume of the storage case 41. Furthermore, multiple recesses 46 are formed on the bottom surface 41A of the storage case 41.

[0062] As shown in Figure 8, when the movable egg storage mechanism 51 is in use, the mounting plate 52 is deployed in a nearly horizontal position relative to the bottom surface 41A of the storage case 41, so as to cover the top of the storage case 41. As described above, the mounting plate 52 is supported at six points by the shaft portion 53, mounting portion 71, recess 72, and protrusion 73, allowing it to be stably deployed in a horizontal position. This prevents the mounting plate 52 from sagging from the horizontal position toward the bottom surface 41A of the storage case 41. As a result, eggs stored on the second-tier mounting plate 52 are prevented from colliding with eggs stored on the bottom surface 41A of the first-tier storage case 41. In addition, although the mounting plate 52 becomes the storage area for eggs on the second tier within the storage case 41, it is designed to prevent eggs from falling due to vibrations when the second insulated door 15 is opened and closed.

[0063] In this embodiment, the description of the refrigerator 10 has focused on the case where the movable egg storage mechanism 51 is installed in the storage case 41 of the second insulated door 15, but the invention is not limited to this case. For example, the movable egg storage mechanism 51 may be installed in the refrigerator compartment 13 on the main body side of the refrigerator 10. In this case, the egg carton can be placed on the upper surface of the partition plate member 16 of the refrigerator compartment 13, and the mounting plate 52 can be extended above it to enable the two-tiered storage described above, achieving a similar effect.

[0064] Furthermore, although the support portion 54 of the movable egg storage mechanism 51 has side plates 66, 67, and 68 and has been described as a self-supporting structure, it is not limited to this case. For example, the support portion 54 may consist of side plates 66 and 67 on which guide grooves 70 and mounting portions 71 are formed. In this case, the side plates 66 and 67 are fitted into assembly grooves (not shown) of the storage case 41 and fixed in a parallel state within the storage case 41. The above-described effect is obtained by rotatably supporting the mounting plate 52 between the side plates 66 and 67. In addition, various modifications are possible without departing from the gist of the present invention. [Explanation of Symbols]
