[0008] Hereinafter, the embodiments of the present disclosure will be described with reference to the accompanying drawings. In addition, in the drawings, the same reference numerals are given to the same or corresponding parts, and the description thereof will not be repeated.

[0009] [Implementation Method 1] Hereinafter, a refrigerator 100 according to an embodiment of the present disclosure will be described with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals to avoid duplication of description.

[0010] The refrigerator 100 is a general term for a device for cooling an object. The refrigerator 100 is equivalent to an example of a cooling box. The object is typically food and drink. Cooling is a concept that includes freezing and refrigeration. "Freezing" is cooling the room temperature to below 0°C. "Refrigeration" is cooling to below room temperature within a temperature range higher than 0°C. As the refrigerator 100, a freezer and a refrigerator are illustrated. The freezer has only a freezer compartment. The freezer compartment is an example of a cooling chamber, and is a space for freezing an object. It is preferred that cold air at a temperature below -18°C is supplied to the freezer compartment. In addition to the freezer compartment, the refrigerator also has a refrigerator compartment. The refrigerator compartment is another example of a cooling chamber, and is a space for refrigerating an object. The refrigerator compartment may also be a so-called vegetable compartment suitable for storing vegetables, which is a specific example of an object. In the embodiment, a refrigerator is described as an example of the refrigerator 100.

[0011] In each figure, the front-rear direction Y, the left-right direction X, and the up-down direction Z are defined as follows. Figure 3 ) is the front Y1 to define the front-rear direction Y. The rear direction Y2 is the opposite direction to the front Y1 and defines the left-right direction X when the refrigerator 100 is viewed from the front Y1. The left-right direction X is orthogonal to the front-rear direction Y and includes the left X1 and the right X2. The up-down direction Z is orthogonal to the front-rear direction Y and the left-right direction X, respectively. The up-down direction Z includes the upper Z1 and the lower Z2.

[0012] Figure 1 It is a front view which shows the refrigerator 100 which concerns on embodiment. Figure 2 yes Figure 1 A perspective view of a refrigerator 100 is shown. Figure 3 Yes means Figure 1 A three-dimensional view of the box 1 is shown.

[0013] like Figure 1 to Figure 3 As shown, the refrigerator 100 includes a heat-insulating housing 1. Cooling chambers 11 to 15 are formed in the housing 1. The cooling chambers 11 to 15 are separated from each other by the housing 1 itself or a partition wall (not shown). The main part of the embodiment is the cooling chamber 13 among the cooling chambers 11 to 15. Therefore, the following description controls the cooling chambers 11, 12, 14, and 15. The cooling chamber 13 is equivalent to an example of a "freezer chamber". The cooling chamber 13 has an opening that opens to the front Y1.

[0014] The housing 1 has, for example, a plurality of walls 131 to 133. In an embodiment, the plurality of walls 131 to 133 divide the cooling chamber 13. The plurality of walls 131 to 133 extend along the front Y1. In an embodiment, the wall 131 is, for example, the bottom wall of the housing 1, defining the lower end of the cooling chamber 13. The walls 132 and 133 are the left and right walls of the housing 1, defining the left and right ends of the cooling chamber 13. The opening 134 is substantially rectangular in shape when viewed from the front Y1 (hereinafter referred to as “front view”). The opening 134 is surrounded by a periphery 17 of the housing 1. The periphery 17 is a portion located around the opening 134 at least at the front ends of the walls 131 to 133 (particularly referring to Figure 3 ).

[0015] The housing 1 also has walls 135, 136 (see in particular Figure 3 ), wall 135 is an inner wall, defining at least a portion of the rear end of cooling chamber 13. Wall 135 is inclined relative to wall 131. Wall 135 is opposite to opening 134 on the rear side in the direction Y2. Wall 136 is a rear wall of housing 1. Wall 136 divides cooling chamber 13 and space 16 different from cooling chamber 13. Space 16 is sometimes also referred to as an equipment room. Space 16 accommodates, for example, a compressor and a water tray.

[0016] In addition, a pair of guide rails 161 and 162 are provided on the inner surfaces of the walls 132 and 133 at positions opposite to each other in the left-right direction X (see Figure 3 The pair of guide rails 161 and 162 are disposed at positions substantially symmetrical to each other in the left-right direction X. The guide rails 161 and 162 extend along the front-rear direction Y and are used to move the drawer 3 along the front-rear direction Y.

[0017] like Figure 3 As shown, the refrigerator 100 includes a cooling unit 2 in a housing 1. In the embodiment, the cooling unit 2 is as shown in FIG. Figure 3 As shown by the middle dotted line, it is arranged in the space 16 and inside the wall 136. However, it is not limited to this, and the cooling unit 2 can also be arranged in the space 16 and inside the walls 132 and 133. The cooling unit 2 generates cold air and transports it to the cooling chambers 11 to 15. The cooling unit 2 is not particularly limited as long as it can supply cold air, and it can be achieved, for example, by a refrigeration cycle (not shown). The refrigeration cycle has a compressor, a condenser, a pressure reducer and an evaporator for the circulation of refrigerant. The cooling unit 2 also has a fan (not shown) that delivers the cold air generated in the refrigeration cycle to the cooling chambers 11 to 15.

[0018] The cooling unit 2 has a flow path 22 for cold air on the housing 1. The flow path 22 guides the cold air generated by the cooling unit 2. The flow path 22 has a plurality of blowing outlets. The plurality of blowing outlets include a blowing outlet 221. The blowing outlet 221 is equivalent to an example of a "cold air blowing outlet". The cold air flowing in the flow path 22 is blown out from the blowing outlet 221 toward the cooling chamber 13. The cold air from the other blowing outlets is blown toward the cooling chambers 11, 12, 14, and 15, respectively. The flow path 22 also has a plurality of suction ports. The plurality of suction ports include a suction port 222. The cold air in the cooling chamber 13 is sucked into the interior of the flow path 22 from the suction port 222. The sucked cold air circulates in the flow path 22 and is transported to the refrigeration cycle.

[0019] Figure 4 Drawer 3 is viewed from the front obliquely above (refer to Figure 2 ) and flow path 22 (refer to Figure 3 ) when the stereogram is Figure 5 It is a diagram schematically showing a cross section of the cooling chamber 13 . Figure 6 yes Figure 5 Other views of the cooling chamber 13 are shown.

[0020] like Figures 2 to 4 As shown, the refrigerator 100 further includes a drawer 3. The drawer 3 has a panel 31, a pair of sliders 321, 322, a container 33 and a housing 113. In the drawer 3, the panel 31 blocks the opening 134 (see Figure 2 , Figure 3 ).like Figure 5 As shown, the position where the panel 31 blocks the opening 134 is sometimes referred to as a “closed position.” When the object is stored and the panel 31 is in the closed position, the container 33 is located in the cooling chamber 13 . That is, the container 33 is stored in the cooling chamber 13 .

[0021] In addition, the container 33 is pulled out from the cooling chamber 13 together with the panel 31. Specifically, the container 33 is pulled out from the cooling chamber 13 in the forward direction Y1 through the opening 134 together with the movement of the panel 31 from the closed position in the forward direction Y1 (see Figure 2 ).like Figure 6 As shown, the position where the container 33 is pulled out from the cooling chamber 13 to the front direction Y1 through the opening 134 is sometimes referred to as an "open position".

[0022] The panel 31 has a rear surface 311. The rear surface 311 is a main surface on the rear direction Y2 side of the two main surfaces of the panel 31 that are spaced apart in the front-to-rear direction Y. When the drawer 3 is in the closed position, the rear surface 311 is aligned with the peripheral edge 17 (see Figure 3 ) abuts against the panel 31. As a result, the panel 31 blocks the opening 134 (see Figure 1 A pair of sliders 321 and 322 are mounted on the rear surface 311 .

[0023] The sliders 321 and 322 are in contact with the guide rails 161 and 162, respectively, and move along the guide rails 161 and 162 (see Figure 3 ) slides in the front-rear direction Y. Thus, the drawer 3 can be in the closed position (refer to Figure 1 ) as a reference, and moves forward in the cooling chamber 13 through the opening 134 and in the rearward direction Y2.

[0024] The container 33 is located in the cooling chamber 13, and is pulled out of the cooling chamber 13 together with the panel 31. Specifically, the container 33 is a box body with a bottom, and has an opening 331 opened upward Z1. The container 33 accommodates an object.

[0025] Specifically, the container 33 includes a wall 332A that is substantially rectangular when viewed from above. The wall 332A is the bottom wall of the container 33. The container 33 also includes walls 332B to 332E that extend upward Z1 from the outer edge of the wall 332A. Figure 3 ) Similarly, wall 332C among walls 332B to 332E is inclined relative to the up-down direction Z and the front-back direction Y, respectively.

[0026] The container 33 is inserted downward Z2 from an opening defined by the panel 31, the sliders 321, 322, and the shaft 34. When a force in the front-rear direction Y is applied to the panel 31 by a user operation, the container 33 is displaced in the front-rear direction Y together with the panel 31.

[0027] like Figure 4 As shown, a plurality of through holes 339 are formed on the periphery 336 of the container 33. Figure 4 In the drawing, only one through hole is marked with the reference symbol "339". A plurality of through holes 339 penetrate the periphery 336 in the up-down direction Z and are arranged in the left-right direction X. Therefore, when the drawer 3 is in the closed position, the cold air blown out from the blow-out port 221 flows above the container 33 in the cooling chamber 13 (see arrow A1). The cold air flows from the top Z1 to the bottom Z2 via the plurality of through holes 339. Afterwards, the cold air flows along the wall 332B and the wall 332A of the container 33 in the cooling chamber 13, and is guided backward by the container 33 (see arrows A2 and A3). Afterwards, the cold air flows from the air inlet 222 into the flow path 22 (see arrow A4). As a result, the object in the container 33 is cooled without temperature unevenness.

[0028] Figure 7 113 is a perspective view showing the housing 113. Figure 7 In the embodiment, a part of the structure of the housing 113 is omitted. The housing 113 accommodates the object. Figures 4 to 6As shown in FIG. 1 , the housing 113 is supported by the container 33. That is, when in the closed position, the housing 113 is accommodated in the cooling chamber 13. When in the open position, the housing 113 is pulled out from the cooling chamber 13 toward the front direction Y1.

[0029] The casing 113 is arranged in front of the air outlet 221 of the cooling chamber 13. The casing 113 includes a casing body 111 and a cover 112.

[0030] The housing body has a recessed portion 1111. The recessed portion 1111 of the housing body 111 is open toward the upper direction Z1. The recessed portion 11111 includes a bottom wall 111a, a pair of side walls 111f, a front wall 111d, and a rear wall 111e.

[0031] An object is arranged on the bottom wall 111a. A pair of side walls 111f extend upward from the ends of the bottom wall 111a in the width direction. The front wall 111d extends upward from the end of the front side of the bottom wall 111a. The rear wall 111e is located closer to the blow-out port 221 than the front wall 111d. The rear wall 111e extends upward from the end of the rear side of the bottom wall 111a. The recess 1111 of the housing 113 is formed by the rear wall 111e, the front wall 111d, the first side wall 111b, and the second side wall 111c.

[0032] The cover 112 covers the recessed portion 1111. The cover 112 has an inclined portion 114. The inclined portion 114 extends upward from one end portion in the front-rear direction Y toward the center side.

[0033] The casing 113 has a plurality of through holes 120 formed at an end portion on the air outlet 221 side. The end portion on the air outlet 221 side is an end portion on the rear direction Y2 side.

[0034] Generally, the air intruding into the cooling chamber is hotter and more humid than the air in the cooling chamber. Therefore, condensation may occur due to the temperature difference. In particular, on the side of the blow-out port 221 of the housing 113, the temperature difference between the air in the recess 1111 of the housing 113 and the cold air outside the housing 113 becomes larger, making it easier for condensation to occur. By forming a through hole 120 at the end on the blow-out port 221 side of the housing 113, the temperature on the blow-out port 221 side of the recess 1111 is reduced by using the cold air flowing into the recess 1111 through the through hole 120 at the end on the blow-out port 221 side of the recess 1111. As a result, the temperature difference between the air in the recess 1111 and the cold air outside the housing 113 becomes smaller. Therefore, the generation of condensation in the cooling chamber can be suppressed.

[0035] The cover 112 covers the recessed portion 1111 of the housing body 111, and the inclined portion 114 of the cover 112 can guide the air upward. The cold air from the air outlet 221 flows into the recessed portion 1111 of the housing body 111 through the plurality of through holes 120. Figure 7In FIG. 1 , only one through hole 120 is denoted by reference numeral “ 120 ”. The plurality of through holes 120 are arranged in the left-right direction X.

[0036] like Figures 5 to 7 As shown, the cover 112 has a trapezoidal shape. That is, the inclined portion 114 of the cover 112 includes a first inclined portion 114A and a second inclined portion 114B. The upper surface of the inclined portion 114 has a flat shape.

[0037] The first inclined portion 114A is located closer to the front direction Y1 than the second inclined portion 114B. The first inclined portion 114A is located closer to the panel 31 than the second inclined portion 114B. The upper surface of the first inclined portion 114A has a flat shape. Figure 7 As shown, the first inclined portion 114A includes a front end portion 114E and a rear end portion 114C. The front end portion 114E is located at a position closer to the front direction Y1 than the rear end portion 114C. In addition, the rear end portion 114C is located at a position closer to the front direction Y1 than the front end portion 114D of the second inclined portion 114B described later. The rear end portion 114C is located at a position higher than the front end portion 114E. That is, the distance from the bottom wall 111a of the housing body 111 to the first inclined portion 114A becomes shorter as the first inclined portion 114A moves from the rear end portion 114C toward the front end portion 114E.

[0038] The second inclined portion 114B is located closer to the rear direction Y2 than the first inclined portion 114A. The second inclined portion 114B is located closer to the blow-out port 221 side than the first inclined portion 114A. The upper surface of the second inclined portion 114B has a planar shape. The second inclined portion 114B includes a front end portion 114D and a rear end portion 114F. The front end portion 114D is located closer to the rear direction Y2 than the rear end portion 114C, and is located closer to the front direction Y1 than the rear end portion 114F. The front end portion 114D is located higher than the rear end portion 114F. That is, the further the second inclined portion 114B moves from the front end portion 114D toward the rear end portion 114F, the shorter the distance from the bottom wall 111a of the shell body 111 to the second inclined portion 114B.

[0039] Front end 114D of second inclined portion 114B is at the same height as rear end 114C of first inclined portion 114A. Rear end 114F is located further back in Y2 direction than front end 114D. Rear end 114F of second inclined portion 114B is at the same height as front end 114D of first inclined portion 114A.

[0040] The center side indicates the area between the front end portion 114E and the rear end portion 114F. Specifically, the center side indicates the area between the rear end portion 114C and the front end portion 114D.

[0041] like Figure 7As shown, the first inclined portion 114 extends upward from the front end portion 114E toward the central side. The second inclined portion 114B extends upward from the rear end portion 114F toward the central side. The first inclined portion 114A and the second inclined portion 114B can guide air upward. Thus, it is possible to prevent air from being guided to the recess 1111 of the housing body 111 from the direction in which the first inclined portion 114A and the second inclined portion 114B are arranged.

[0042] In addition, in the embodiment, if Figure 6 As shown, when the drawer 3 is pulled out from the cooling chamber 13, the air outside the cooling chamber 13 is sometimes introduced into the cooling chamber 13. The air pressure inside the cooling chamber 13 is lower than the air pressure outside the cooling chamber 13. The air moves from the portion with high air pressure to the portion with low air pressure. Therefore, the air outside flows into the cooling chamber 13. Moreover, the air outside the cooling chamber 13 is warmer than the air inside the cooling chamber 13. The air flowing in from the outside (see arrow A6) moves upward along the first inclined portion 114A (see arrow A7). As a result, the air flowing in from the outside does not stay on the front side of the shell body 111, but moves toward the center side of the shell body 111 while moving toward the top of the shell body 111. As a result, it is possible to further suppress the shell body 111 from being heated by the warm air outside the cooling chamber 13.

[0043] like Figure 7 As shown, the cover 112 further includes a horizontal portion 118 and a pair of side walls 119 .

[0044] A pair of side walls 119 are disposed on the housing body 111. The pair of side walls 119 are located on the left X1 and the right X2 of the inclined portion 114. In addition, the pair of side walls 119 are located on the left X1 and the right X2 of the horizontal portion 118. That is, the pair of side walls 119 covers between the housing body 111 and the inclined portion 114. In addition, the pair of side walls 119 covers between the housing body 111 and the horizontal portion 118.

[0045] The horizontal portion 118 is located between the first inclined portion 114A and the second inclined portion 114B. The horizontal portion 118 covers the recessed portion 1111 of the housing body 111 corresponding to the portion between the first inclined portion 114A and the second inclined portion 114B.

[0046] The horizontal portion 118 connects the rear end portion 114C of the first inclined portion 114A and the front end portion 114D of the second inclined portion 114B. Therefore, the horizontal portion 118 covers from the rear end portion 114C of the first inclined portion 114A to the front end portion 114D of the second inclined portion 114B. As a result, it is possible to prevent the air guided upward by the inclined portion 114 from entering the interior of the housing 113 from between the rear end portion 114C and the front end portion 114D.

[0047] The housing 113 further includes an area 223 to which cold air is blown from the blow-out port 221. Figure 7 As shown by the arrow, the cold air from the blowing port 221 is blown toward the housing 113 in the forward direction Y1. The region 223 is provided across the cover 112 and the rear wall 111e. Specifically, the region 223 is located closer to the forward direction Y1 than the first inclined portion 114A of the cover 112, and is located on the upper Z1 side of the rear wall 111e.

[0048] The through hole 120 is formed in the region 223 when the housing 113 is disposed in the cooling chamber 13. Thus, cold air is blown to the through hole 120. As a result, a larger amount of cold air can flow into the recess 1111, and a temperature rise in the recess 1111 can be suppressed, compared with a case where cold air is not blown to the through hole 120.

[0049] The through hole 120 has an elongated shape extending along the flow direction of the cold air from the blowout port 221 when the housing 113 is disposed in the cooling chamber 13. Therefore, the through hole 120 has a function of rectifying the flow of the cold air. As a result, the cold air easily flows into the interior of the housing 113.

[0050] At least a portion of the through hole 120 is formed in the cover 112. Specifically, the cover 112 is provided with a through hole 120A. When the through hole 120A is provided in the cover 112 located above the housing body 111, the air inside the housing 113, which is warmer than the cold air, is easily leaked from the through hole 120A.

[0051] The through hole 120A reaches the edge 112g on the side of the blow-out port 221 of the cover 112. In other words, the through hole 120A is a slit extending from the edge 112g on the side of the blow-out port 221 along the front direction Y1. When the through hole 120A is formed into a shape that reaches the edge 112g, cold air also flows into the interior of the housing 113 from the edge 112g, so that a larger amount of cold air can be easily flowed into the interior of the housing 113. In addition, if the through hole 120A is formed into a shape that reaches the edge 112g, compared with the case of forming a hole surrounded by components all around, manufacturing becomes easier, and the amount of raw materials can be reduced, thereby reducing manufacturing costs.

[0052] The rear wall 111e is provided with a through hole 120B. The through hole 120B reaches the end edge 111g at the upper Z1 of the rear wall 111e. In other words, the through hole 120B is a slit extending from the end edge 111g toward the lower Z2.

[0053] When the lid 112 covers the recess 1111, the through hole 120A and the through hole 120B are connected to each other to form the through hole 120. Alternatively, only one of the through hole 120A and the through hole 120B may be provided.

[0054] In addition, if Figure 7 As shown in FIG. 1 , the cover 112 of the present embodiment is further formed with another through hole H in a region on the front side of the region 223 where the through hole 120 is formed. The heated air in the housing 113 is pushed upward to the Z1 side by the cold air that flows into the housing 113 through the through hole 120, and rises to the cover 112 side. As a result, the heated air can be easily discharged from the through hole H.

[0055] The through hole H penetrates the inside of the housing 113 and the outside of the housing 113. Specifically, a plurality of through holes H are formed in the cover 112. Figure 7 In the figure, only one through hole is marked with the reference symbol "H". The plurality of through holes H are arranged from the first inclined portion 114A to the second inclined portion 114B. The opening area of ​​the through hole 120 is larger than the opening area of ​​the through hole H. Thus, the inflow of cool air from the through hole 120 is promoted.

[0056] Specifically, the first inclined portion 114A has a plurality of through holes HA. The through holes HA are formed from the front end portion 114E of the first inclined portion 114A to the rear end portion 114C of the first inclined portion 114A. In the housing 113, the heated air moves along the first inclined portion 114A. And, the heated air is discharged to the outside of the housing 113 from the plurality of through holes HA.

[0057] The second inclined portion 114B has a plurality of through holes HB. The plurality of through holes HB are formed from the rear end portion 114F of the second inclined portion 114B to the front end portion 114D of the second inclined portion 114B. In the housing 113, the heated air moves along the second inclined portion 114B. And, the heated air is discharged to the outside of the housing 113 from the plurality of through holes HB.

[0058] The horizontal portion 118 has a plurality of through holes HC. That is, the through holes HC are formed in the horizontal portion 118. In the housing 113, the heated air moves along the first inclined portion 114A toward the rear end portion 114C of the first inclined portion 114A. In addition, in the housing 113, the heated air moves along the second inclined portion 114B toward the front end portion 114D of the second inclined portion 114B. Since the horizontal portion 118 is connected to the rear end portion 114C of the first inclined portion 114A and the front end portion 114D of the second inclined portion 114B, the heated air moves toward the horizontal portion 118. Therefore, the heated air is discharged from the through holes HC of the horizontal portion 118 to the outside of the housing 113.

[0059] In addition, in the present embodiment, the first inclined portion 114A, the second inclined portion 114B, and the horizontal portion 118 each have a through hole H, but the present invention is not limited thereto. For example, the through hole H may be disposed on any one of the first inclined portion 114A, the second inclined portion 114B, and the horizontal portion 118. For example, the through hole H may be disposed only on the horizontal portion 118. In addition, when the through hole H is disposed on the horizontal portion 118, the through hole H may not be disposed on the first inclined portion 114A and the second inclined portion 114B.
