[0009] Hereinafter, each embodiment of the present invention will be described with reference to the drawings. In the following description, the same parts are given the same reference numerals. Their names and functions are also the same. Therefore, detailed descriptions thereof will not be repeated. In the following description, directions such as front, back, left and right refer to directions as viewed from the user using the refrigerator.

[0010] <First embodiment> In this embodiment, a refrigerator 1 having one cooling chamber will be described as an example. However, in the present invention, the refrigerator is not limited to the refrigerator 1. In the present invention, the "refrigerating chamber" refers to any chamber having an internal space (cooling chamber) at a temperature lower than the outside air temperature and capable of lowering the temperature of the contents contained therein. The refrigerator may be, for example, a refrigerator or a freezer. The refrigerator may have only one cooling chamber or may have multiple cooling chambers. The cooling chamber may be a chamber in which the temperature inside the cooling chamber is controlled to approach a predetermined cooling temperature, such as, for example, about 5°C, about 0°C, about -18°C, or about -23°C. The cooling chamber may be set to multiple cooling temperatures. When the refrigerator has multiple cooling chambers, the multiple cooling chambers may include at least two of a refrigerator chamber, a freezer chamber, a vegetable chamber, a chilled chamber, a partial chamber, and the like.

[0011] (Overall configuration of the cooling cabinet) The refrigerator 1 will be described mainly with reference to Figures 1 and 2. Figure 1 is a diagram showing the external appearance of the refrigerator 1. Figure 2 is a diagram showing the inside of a cooling chamber 10 of a housing 50 provided in the refrigerator 1.

[0012] The exterior shape of the refrigerator 1 is mainly formed by a housing 50 and a door 11. The housing 50 includes an outer box 51, an inner box 52, and a heat insulating material (not shown). The inner box 52 is also called a hood liner.

[0013] In this embodiment, the surface on which the door 11 is provided is referred to as the front surface or front face of the refrigerator 1. Based on the front surface as a reference, the respective surfaces of the refrigerator 1 are referred to as the top surface, side surface, back surface, and bottom surface based on the positions where the refrigerator 1 would exist if installed in a normal state.

[0014] As shown in Figs. 1 and 2, the refrigerator 1 includes a housing 50. The housing 50 may be, for example, a thermally insulated box. The term "thermally insulated box" refers to a box having walls that include a thermally insulated material. Examples of the thermally insulated material include a foam material having multiple pores, a member having a reduced pressure internal space, and the like.

[0015] The housing 50 has a cooling chamber 10. The cooling chamber 10 is a chamber for cooling an item. In this embodiment, the housing 50 has one cooling chamber 10. The cooling chamber 10 opens toward the front. The cooling box 1 has a door 11 in addition to the housing 50. The door 11 is attached to the housing 50 so as to be able to open and close the opening of the cooling chamber 10. Specifically, the door 11 is attached to the housing 50 so as to be able to rotate. The opening of the cooling chamber 10 is opened and closed by the door 11 rotating relative to the housing 50. The door 11 is preferably an insulated door having a heat insulating material.

[0016] (Configuration of the cooling chamber) The inner wall of the cooling chamber 10 is formed by an inner box 52 or the like. At least one shelf is provided inside the cooling chamber 10. In one example, one storage shelf 40 is provided below the cooling chamber 10. The storage shelf 40 is an example of a shelf board. Although not shown in FIG. 3 etc., one or more substantially flat shelves may be provided above the cooling chamber 10.

[0017] The storage shelf 40 is removable from the cooling chamber 10. The front wall 41 of the storage shelf 40 has a lower wall 41a and an upper wall 41b that are divided in the vertical direction. The lower wall 41a and the upper wall 41b correspond to the main body of the front wall 41 (front wall main body). The upper wall 41b is removable from the storage shelf 40 main body. The upper wall 41b removed from the storage shelf 40 main body is attached to the storage shelf 40 by changing its position from the state shown in FIG. 2.

[0018] Fig. 3 shows a state in which the position of the upper wall portion 41b is changed from the state shown in Fig. 2. The position of the upper wall portion 41b shown in Fig. 2 is called a first state or a first posture, and the position of the upper wall portion 41b shown in Fig. 3 is called a second state or a second posture. In the first state, the upper wall portion 41b is disposed above the lower wall portion 41a. In addition, in the second state, the upper wall portion 41b is disposed in front of the lower wall portion 41a so as to overlap with the lower wall portion 41a.

[0019] In the first state, the storage shelf 40 can be pulled out toward the front, whereas in the second state, the storage shelf 40 cannot be pulled out in the front-rear direction.

[0020] (Storage Shelf Configuration) Next, the configuration of storage shelf 40 will be described. Figures 4 and 5 are diagrams showing the external appearance of storage shelf 40. Figure 4 is a diagram showing storage shelf 40 with upper wall portion 41b arranged in a first state. Figure 5 is a diagram showing a state in which upper wall portion 41b has been removed from storage shelf 40 main body.

[0021] The storage shelf 40 has a box-like shape. The storage shelf 40 is disposed at the lowest level in the cooling chamber 10, and is suitable for storing relatively heavy items (e.g., one-liter bottles, beverage bottles, etc.). The location of the storage shelf 40 in the cooling chamber 10 is not limited to the lowest level. In another embodiment, the storage shelf 40 may be disposed at a middle level in the cooling chamber 10.

[0022] The storage shelf 40 has a bottom wall portion 45, a front wall portion 41, a rear wall portion 42, a first side wall portion 43, and a second side wall portion 44. The bottom wall portion 45 forms the bottom surface of the box-shaped storage shelf 40. The front wall portion 41 stands up from a front side end portion of the bottom wall portion 45. The rear wall portion 42 stands up from a rear side end portion of the bottom wall portion 45.

[0023] The first side wall portion 43 stands up from one end portion in the first left-right direction of the bottom wall portion 45. The second side wall portion 44 stands up from the other end portion in the left-right direction of the bottom wall portion 45. In this embodiment, the first side wall portion 43 forms the left side wall when viewed from the front, and the second side wall portion 44 forms the right side wall when viewed from the front.

[0024] The front wall 41, the rear wall 42, the first side wall 43, and the second side wall 44 stand upright from each side end of a substantially rectangular bottom wall 45. That is, the front wall 41, the rear wall 42, the first side wall 43, and the second side wall 44 form each side wall of the storage shelf 40. As shown in Fig. 4, in the first state, the four side walls (that is, the front wall 41, the rear wall 42, the first side wall 43, and the second side wall 44) are all approximately the same height.

[0025] The front wall portion 41 has a lower wall portion 41a and an upper wall portion 41b. When the upper wall portion 41b is disposed in a first state (i.e., in the state shown in Figs. 2 and 4), the upper wall portion 41b is disposed above the lower wall portion 41a. The upper wall portion 41b and the lower wall portion 41a are substantially flush with each other.

[0026] A handle portion 47 is provided on the upper end of the upper wall portion 41b. The handle portion 47 has a shape in which the upper end portion of the upper wall portion 41b is bent downward. The handle portion 47 is used as a handle when pulling the storage shelf 40 forward.

[0027] The second side wall portion 44 is provided with a protrusion 46 that protrudes laterally. As shown in Fig. 4, the protrusion 46 extends in the front-rear direction on the outer surface of the second side wall portion 44. Similarly, the first side wall portion 43 is also provided with a protrusion 46 that protrudes laterally and extends in the front-rear direction.

[0028] This protrusion 46 fits into a recess 54 provided on a side surface 52b of the inner box 52. For example, when a user of the cooling box 1 puts his or her hand on the handle 47 of the storage shelf 40 and pulls the storage shelf 40 towards himself or herself, the protrusion 46 slides in the front-to-rear direction within the recess 54. As a result, the storage shelf 40 is smoothly pulled out towards himself or herself.

[0029] As shown in Fig. 5, the upper wall portion 41b is removable from the main body of the storage shelf 40. When the upper wall portion 41b is removed from the storage shelf 40, it is placed in a position different from the first state shown in Fig. 2. Specifically, the lower plate-shaped portion of the upper wall portion 41b (the portion other than the handle portion 47) is inserted into the upper wall housing portion 48 formed on the front side of the lower wall portion 41a. This state is called the second state.

[0030] In the second state, the upper wall portion 41b is disposed in front of the lower wall portion 41a so as to overlap with the lower wall portion 41a. Therefore, the height of the front wall portion 41 is lower than the height of other walls (for example, the first side wall portion 43, etc.) (see FIG. 3). In this way, in the second state, the front side of the cooling chamber 10 is in a more open state, so that it becomes easier to store tall objects such as one-liter bottles and beverage bottles in the storage shelf 40.

[0031] In the second state, the upper wall portion 41b is attached to the wall surface of the cooling chamber 10 and is fixed inside the cooling chamber 10. This makes it impossible for the storage shelf 40 to be pulled out in the front-rear direction.

[0032] One method for fixing the upper wall portion 41b inside the cooling chamber 10 is to fit one end of the upper wall portion 41b into a recess provided in the wall surface of the cooling chamber 10.

[0033] 6 shows the storage shelf 40 arranged in the cooling chamber 10 with the upper wall portion 41b in the second state. When the storage shelf 40 is arranged at the lowest level of the cooling chamber 10 as in this embodiment, the bottom surface 52a of the inner box 52 is provided with a recess 55 into which one end portion of the upper wall portion 41b (specifically, the lower end portion 49a) is fitted.

[0034] In the second state, the lower end 49a of the upper wall portion 41b projects downward from the lower end of the upper wall accommodating portion 48 and is inserted into the recess 55 in the bottom surface 52a of the inner box 52. As a result, the storage shelf 40 body accommodating the upper wall portion 41b in the upper wall accommodating portion 48 is fixed to the cooling chamber 10.

[0035] As described above, in the cooling cabinet 1 according to this embodiment, the upper wall portion 41b of the storage shelf 40 can be arranged in two different states, a first state and a second state. By selectively using the first state and the second state depending on the purpose of the cooling cabinet 1 and the type of contents to be stored in the cooling chamber 10, a more convenient cooling cabinet 1 can be provided.

[0036] For example, when the upper wall portion 41b is arranged in the first state, the storage shelf 40 may be used as, for example, a vegetable case for storing vegetables, fruits, etc. In this case, it is preferable to arrange a flat shelf board above the storage shelf 40. By arranging the flat shelf board close to the upper end of the storage shelf 40, the closedness of the space within the storage shelf 40 can be increased, and drying within the space can be suppressed.

[0037] On the other hand, when the upper wall portion 41b is arranged in the second state, it is desirable to store heavier objects, such as one-liter bottles, in the storage shelf 40. Note that heavier objects are often relatively tall. For this reason, it is advisable to secure a larger space above the storage shelf 40 by, for example, arranging a flat shelf board higher up or removing shelves other than the storage shelf 40 from the cooling chamber 10.

[0038] In the second state, the height of the front wall portion 41 is lowered, which makes it easier to take in and out relatively tall objects such as one-liter bottles and beverage bottles from within the cooling chamber 10.

[0039] As described above, in the refrigerator 1 according to this embodiment, the storage shelf 40 can be used for various purposes depending on how the upper wall portion 41b is arranged. For example, when the upper wall portion 41b is arranged in the first state, the storage shelf 40 can be used as a box-shaped storage space. By using the storage shelf 40 as a box-shaped storage space, it is possible to suitably store relatively small items that tend to roll, such as vegetables and fruits. On the other hand, when the upper wall portion 41b is arranged in the second state, tall bottles such as one-liter bottles can be refrigerated in an upright state.

[0040] (Summary of the first embodiment) As described above, the cooling box 1 according to this embodiment includes a housing 50 having a cooling chamber 10, and a storage shelf (shelf) 40 arranged in the cooling chamber 10. The storage shelf 40 has a bottom wall 45 and a front wall 41 standing up from a front side end of the bottom wall 45. The front wall 41 has a lower wall 41a and an upper wall 41b divided in the vertical direction. The upper wall 41b is configured so that its position can be changed from an arrangement position above the lower wall 41a, and the upper wall 41b in the changed position is attached to the housing 50 (specifically, the wall surface of the inner box 52) and prevents the storage shelf 40 from being pulled out in the front-rear direction.

[0041] The storage shelf 40 in the non-retractable state can be used as a tray for storing tall objects such as one-liter bottles in an upright position. By making the storage shelf 40 non-retractable, it is possible to prevent tall objects from tipping over. Furthermore, the presence of a short front wall portion 41 at the front end of the storage shelf 40 (see FIG. 3) makes it possible to prevent objects from unintentionally tilting forward.

[0042] In addition, in the above-mentioned storage shelf 40, when the upper wall portion 41b is disposed above the lower wall portion 41a, the storage shelf 40 can be pulled out in the front-rear direction. In this case, the storage shelf 40 becomes a box-type storage shelf due to the presence of the front wall portion 41 that is taller at the front end portion (see FIG. 2).

[0043] As described above, according to the configuration of this embodiment, by changing the arrangement of the upper wall portion 41b provided on the storage shelf 40, one storage shelf 40 can be used in both the form of a tray and a box. Therefore, it is possible to provide a more convenient cooling box 1.

[0044] <Second embodiment> Next, a second embodiment of the present invention will be described. In the first embodiment, a configuration in which the storage shelf 40 is arranged at the lowest level of the cooling chamber 10 has been described. In the second embodiment, a configuration in which the storage shelf 40 is arranged at the middle level of the cooling chamber 10 will be described.

[0045] Figures 7 to 10 show a storage shelf 40 arranged in a cooling chamber 10 of a refrigerator 1 according to a second embodiment. Figures 7 and 9 show the storage shelf 40 with the upper wall portion 41b arranged in a first state. Figures 8 and 10 show the storage shelf 40 with the upper wall portion 41b arranged in a second state.

[0046] As in the first embodiment, the front wall 41 of the storage shelf 40 has a lower wall 41a and an upper wall 41b. In a first state, the upper wall 41b is disposed above the lower wall 41a. In a second state, the upper wall 41b is disposed in front of the lower wall 41a so as to overlap the lower wall 41a.

[0047] In the first state, the storage shelf 40 can be pulled out toward the front, whereas in the second state, the storage shelf 40 cannot be pulled out in the front-rear direction.

[0048] In this embodiment, the upper portion of the upper wall portion 41b (i.e., the portion where the handle portion 47 is provided) protrudes on both the left and right sides. These protruding portions of the upper wall portion 41b are referred to as an upper left end portion 149a and an upper right end portion 149b, respectively. Also, in this embodiment, a recess 54 provided on the side surface 52b of the inner box 52 is further provided on the front side thereof with a recess 154a extending in the up-down direction.

[0049] In the second state, the upper left end 149a and the upper right end 149b of the upper wall portion 41b are fitted into the recess 154a in the side surface 52b of the inner box 52. As a result, the upper wall portion 41b is fixed to the wall surface of the cooling chamber 10, and the storage shelf 40 cannot be pulled out in the front-rear direction.

[0050] When changing the position of the upper wall portion 41b, the upper wall portion 41b may be temporarily removed from the storage rack 40 body and then attached at a different position, as in the first embodiment.

[0051] As another method, the position of the lower wall portion 41a may be changed by sliding the lower wall portion 41a up and down in front of the upper wall portion 41b without removing the upper wall portion 41b from the main body of the storage rack 40. In this case, for example, the upper wall portion 41b is first moved forward as shown by the arrow in Fig. 9. Then, the upper wall portion 41b is moved downward as shown by the arrow in Fig. 8.

[0052] In another embodiment, the front wall does not have to be divided into an upper wall and a lower wall. That is, the front wall may be formed of a single front wall body. In such a configuration, the front wall body is displaceable between a first position forming the upper end of the front wall and a second position located below the upper end of the front wall. In addition, the shelf board is configured such that in the second position, the front wall body engages with the housing, thereby making it impossible for the shelf board to be drawn out of the housing.

[0053] For example, the front wall body may be configured to be slidable between the front surface and the bottom surface of the storage shelf 40. In such a configuration, in the first position, the front wall body forms the front surface of the storage shelf 40, and the upper end of the front wall body is at substantially the same height as the upper end of other walls (e.g., the first side wall 43, etc.). Then, the front wall body slides and enters the lower surface of the bottom wall 45 of the storage shelf 40. This places the storage shelf 40 in the second position. In this second position, a part of the front wall body (e.g., the handle 47) is fitted into a recess 55 provided on the bottom surface 52a of the inner box 52. This makes it impossible for the storage shelf 40 to be drawn out of the housing 50.

[0054] <Third embodiment> Next, a third embodiment of the present invention will be described. Fig. 11 shows the inside of a cooling chamber 10 of a refrigerator 1 according to the third embodiment.

[0055] A storage shelf 40 is provided inside the cooling chamber 10. The storage shelf 40 is removable from the cooling chamber 10. A front wall 41 of the storage shelf 40 has a lower wall 41a and an upper wall 41b that are divided in the vertical direction. The upper wall 41b is removable from the storage shelf 40 body.

[0056] As in the first embodiment, in the first state, the upper wall portion 41b is disposed above the lower wall portion 41a, and the upper wall portion 41b and the lower wall portion 41a are substantially flush with each other.

[0057] In the first embodiment, when changing the position of the upper wall portion 41b from the first state to the second state, the upper wall portion 41b arranged above the lower wall portion 41a is removed and then inserted into the upper wall accommodating portion 48 provided on the front side of the lower wall portion 41a.

[0058] On the other hand, in this embodiment, the upper wall portion 41b detached from the storage shelf 40 body is attached to the wall surface of the cooling chamber 10 in a state in which it is turned upside down and upside down. Fig. 12 shows the storage shelf 40 in which the upper wall portion 41b is arranged in the second state.

[0059] A recess 55 is provided on the front side of the bottom surface 52a of the inner box 52, into which one end of the upper wall portion 41b (specifically, the upper end portion where the handle portion 47 is provided) is fitted (see FIG. 11). In the second state, the upper end portion of the upper wall portion 41b is located downward and fitted into the recess 55 of the bottom surface 52a. The upper wall portion 41b is located in front of the lower wall portion 41a, and is fixed to the bottom surface 52a of the cooling chamber 10. The movement of the storage shelf 40 toward the front side is restricted by the upper wall portion 41b. In other words, the storage shelf 40 cannot be pulled out in the front-rear direction.

[0060] As described above, in the cooling cabinet 1 according to this embodiment, the upper wall portion 41b of the storage shelf 40 can be arranged in two different states, a first state and a second state. By selectively using the first state and the second state depending on the purpose of the cooling cabinet 1 and the type of contents to be stored in the cooling chamber 10, a more convenient cooling cabinet 1 can be provided.

[0061] The position of the upper wall portion 41b in the second state is not limited to the example shown in Fig. 12. Fig. 13 shows a configuration in which the upper wall portion 41b is disposed inside the storage shelf 40. A cutout portion 45a is provided on the front side of the bottom wall portion 45 of the storage shelf 40 shown in Fig. 13. Although not shown, a recess is formed in the bottom surface 52a of the cooling chamber 10 at a position corresponding to the cutout portion 45a formed in the storage shelf 40.

[0062] 13, when the upper wall portion 41b is arranged in the second state, the upper wall portion 41b arranged above the lower wall portion 41a is removed, and then the lower end portion 49a of the upper wall portion 41b is inserted into the notch portion 45a provided in the bottom wall portion 45 of the storage shelf 40. The lower end portion 49a inserted into the notch portion 45a is further inserted into a recessed portion provided in the bottom surface 52a of the cooling chamber 10. As a result, the upper wall portion 41b and the main body of the storage shelf 40 are fixed to the cooling chamber 10, and the storage shelf 40 cannot be pulled out in the front-rear direction.

[0063] <Fourth embodiment> Next, a fourth embodiment of the present invention will be described. Fig. 14 shows a storage shelf 40 arranged in a cooling chamber 10 of a refrigerator 1 according to the fourth embodiment. The configuration of the refrigerator 1 other than the storage shelf 40 can be the same as that of the first embodiment.

[0064] The storage shelf 40 is removable from the cooling chamber 10. The front wall 41 of the storage shelf 40 has a lower wall 41a and an upper wall 41b that are divided in the vertical direction. The lower wall 41a and the upper wall 41b are connected via a connection portion 41c provided at the upper end of the lower wall 41a. The upper wall 41b is configured to be rotatable at the connection portion 41c.

[0065] Specifically, the connection portion 41c has a cam groove (indicated by a dashed line in FIG. 14) that extends in the front-rear direction. A pin 41d that moves back and forth is provided in the cam groove. The pin 41d is connected to the lower end of the upper wall portion 41b. As indicated by the arrow in FIG. 14, the upper wall portion 41b is configured to be rotatable with the pin 41d as a starting point.

[0066] In the first state, the upper wall portion 41b is disposed above the lower wall portion 41a. In the first state, the storage shelf 40 can be pulled out toward the front.

[0067] When the upper wall portion 41b is changed from the first state to the second state, the upper wall portion 41b is moved forward along the cam groove as shown by the arrow in Fig. 14, and then rotated downward and forward from the pin 41d as a starting point. Then, the upper end portion of the upper wall portion 41b is fitted into the recess 55 of the bottom surface 52a. This makes it impossible for the storage shelf 40 to be pulled out in the front-rear direction.

[0068] In the second state, the upper wall portion 41b is disposed in front of the lower wall portion 41a so as to overlap with the lower wall portion 41a, and the height of the front wall portion 41 is lowered. This makes it easier to take in and out relatively tall stored items such as one-liter bottles and beverage bottles from within the cooling chamber 10.

[0069] The embodiments disclosed herein should be considered to be illustrative and not restrictive in all respects. The scope of the present invention is indicated by the claims, not by the above description, and is intended to include all modifications within the meaning and scope of the claims.
