[0008] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference characters and description thereof will not be repeated.

[0009] [Embodiment 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 symbols, and the repeated description will be avoided.

[0010] The refrigerator 100 is a general term for a device that cools an object. The refrigerator 100 corresponds to an example of a cooling chamber. The object is typically food or drink. Cooling is a concept that includes freezing and refrigeration. "Freezing" means cooling the room temperature to 0°C or lower. "Refrigeration" means cooling below room temperature in a temperature range higher than 0°C. Examples of the refrigerator 100 include a freezer and a refrigerator. The freezer has only a freezer compartment. The freezer compartment is an example of a cooling chamber, and is a space in which an object is frozen. It is preferable that cold air at a temperature of -18°C or lower is supplied to the freezer compartment. The refrigerator has a refrigerator compartment in addition to the freezer compartment. The refrigerator compartment is another example of a cooling chamber, and is a space in which an object is refrigerated. The refrigerator compartment may be a so-called vegetable compartment suitable for preserving vegetables, which is a specific example of the object. In the embodiment, a refrigerator will be described as an example of the refrigerator 100.

[0011] In addition, in each drawing, the front-rear direction Y, the left-right direction X, and the up-down direction Z are defined as follows. That is, the front-rear direction Y is defined with the direction in which the opening 134 (see FIG. 3) faces as the front Y1. The rear Y2 is the opposite direction to the front Y1. The left-right direction X is defined when the refrigerator 100 is viewed from the front Y1. The left-right direction X is perpendicular to the front-rear direction Y and includes the left X1 and the right X2. The up-down direction Z is perpendicular to each of the front-rear direction Y and the left-right direction X. The up-down direction Z includes the upper Z1 and the lower Z2.

[0012] Fig. 1 is a front view showing a refrigerator 100 according to an embodiment. Fig. 2 is a perspective view of the refrigerator 100 shown in Fig. 1. Fig. 3 is a perspective view showing the housing 1 shown in Fig. 1.

[0013] As shown in Figs. 1 to 3, the refrigerator 100 includes a housing 1 having thermal insulation properties. The housing 1 includes cooling compartments 11 to 15. The cooling compartments 11 to 15 are separated from each other by the housing 1 itself or by partitions (not shown). The essential part of the embodiment is the cooling compartment 13 among the cooling compartments 11 to 15. Therefore, hereinafter, a description of the cooling compartments 11, 12, 14, and 15 will be omitted. The cooling compartment 13 corresponds to an example of a "freezer compartment." The cooling compartment 13 has an opening that opens toward the front Y1.

[0014] The housing 1 has, for example, a plurality of walls 131 to 133. In the embodiment, the plurality of walls 131 to 133 define the cooling chamber 13. The plurality of walls 131 to 133 extend along the forward direction Y1. In the embodiment, the wall 131 is, for example, a bottom wall of the housing 1 and defines the lower end of the cooling chamber 13. The walls 132 and 133 are left and right walls of the housing 1 and define the left and right ends of the cooling chamber 13. The opening 134 has a substantially rectangular shape in a plan view from the forward direction Y1 (hereinafter, referred to as a "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 (see FIG. 3 in particular).

[0015] The housing 1 further has walls 135, 136 (see FIG. 3 in particular). The wall 135 is a rear wall and defines at least a portion of the rear end of the cooling chamber 13. The wall 135 is inclined relative to the wall 131. The wall 135 faces the opening 134 on the rear Y2 side. The wall 136 is a rear wall of the housing 1. The wall 136 separates the cooling chamber 13 from a space 16 that is different from the cooling chamber 13. The space 16 is sometimes called a machine room. The space 16 houses, for example, a compressor and a water tray.

[0016] Furthermore, a pair of guide rails 161, 162 (see FIG. 3) are provided on the inner surfaces of the walls 132, 133 at positions facing each other in the left-right direction X. The pair of guide rails 161, 162 are provided at positions approximately symmetrical to each other in the left-right direction X. The guide rails 161, 162 extend along the front-rear direction Y and are provided to move the drawer 3 along the front-rear direction Y.

[0017] As shown in FIG. 3, the refrigerator 100 includes the cooling unit 2 in the housing 1. In the embodiment, the cooling unit 2 is arranged in the space 16 and inside the wall 136 as shown by the dashed line in FIG. 3. The cooling unit 2 may be arranged in the space 16 and inside the walls 132 and 133. The cooling unit 2 generates cold air and sends 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 can be realized, for example, by a refrigeration cycle (not shown). The refrigeration cycle has a compressor, a condenser, a pressure reducer, and an evaporator through which a refrigerant circulates. The cooling unit 2 further has a fan (not shown) that sends the cold air generated by the refrigeration cycle to the cooling chambers 11 to 15.

[0018] The cooling unit 2 includes a cold air flow path 22 in 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 air outlets. The plurality of air outlets includes an air outlet 221. The air outlet 221 corresponds to an example of a "cold air outlet". From the air outlet 221, the cold air that has circulated in the flow path 22 is blown out toward the cooling chamber 13. The cold air from the other air outlets is blown out toward the cooling chambers 11, 12, 14, and 15, respectively. The flow path 22 further includes a plurality of suction ports. The plurality of suction ports includes an suction port 222. From the suction port 222, the cold air in the cooling chamber 13 is sucked into the flow path 22. The sucked cold air flows through the flow path 22 and is sent to the refrigeration cycle.

[0019] Fig. 4 is a perspective view of the drawer 3 (see Fig. 2) and the flow path 22 (see Fig. 3) when viewed obliquely from above the front. Fig. 5 is a diagram showing a schematic cross section of the cooling chamber 13. Fig. 6 is another diagram of the cooling chamber 13 shown in Fig. 5.

[0020] As shown in Figs. 2 to 4, 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 case 113. In the drawer 3, the panel 31 closes the opening 134 (see Figs. 2 and 3). As shown in Fig. 5, the position in which the panel 31 closes the opening 134 may be referred to as the "closed position". When an object is stored therein 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] Moreover, the container 33 is pulled out from the cooling chamber 13 together with the panel 31. In detail, the container 33 is pulled out from the cooling chamber 13 in the forward direction Y1 through the opening 134 as the panel 31 moves in the forward direction Y1 from the closed position (see FIG. 2). As shown in FIG. 6, the position where the container 33 is pulled out from the cooling chamber 13 in the forward direction Y1 through the opening 134 may be referred to as the "open position".

[0022] The panel 31 has a rear surface 311. Of the two main surfaces of the panel 31 that are spaced apart in the front-rear direction Y, the rear surface 311 is the main surface on the rear direction Y2 side. When the drawer 3 is in the closed position, the rear surface 311 abuts against the peripheral edge 17 (see FIG. 3). In this way, the panel 31 closes the opening 134 (see FIG. 1). A pair of sliders 321, 322 are attached to the rear surface 311.

[0023] The sliders 321, 322 slide in the front-rear direction Y along the guide rails 161, 162 (see FIG. 3) while abutting against the guide rails 161, 162, respectively. This allows the drawer 3 to move in the front Y1 and rear Y2 directions within the cooling chamber 13 through the opening 134 with the closed position (see FIG. 1) as a reference.

[0024] The container 33 is located within the cooling chamber 13, and is pulled out to the outside of the cooling chamber 13 together with the panel 31. In detail, the container 33 is a box body with a bottom, and has an opening 331 that opens toward the upper side Z1. The container 33 contains an object.

[0025] In detail, the container 33 has a wall 332A that is substantially rectangular in plan view. The wall 332A is a bottom wall of the container 33. The container 33 further has walls 332B to 332E extending upward Z1 from an outer edge of the wall 332A. Of the walls 332B to 332E, the wall 332C is inclined with respect to both the up-down direction Z and the front-rear direction Y, similar to the wall 135 (see FIG. 3).

[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 is applied to the panel 31 in the front-rear direction Y by a user operation, the container 33 is displaced in the front-rear direction Y together with the panel 31.

[0027] As shown in FIG. 4, a plurality of through holes 339 are formed in the periphery 336 of the container 33. In FIG. 4, only one through hole is denoted by the reference symbol "339". The 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 air outlet 221 flows above the container 33 in the cooling chamber 13 (see arrow A1). The cold air flows from the upper Z1 to the lower Z2 through the plurality of through holes 339. After that, the cold air flows along the wall 332B and the wall 332A of the container 33 in the cooling chamber 13, and is then guided rearward from the container 33 (see arrows A2 and A3). Then, the cold air flows from the air inlet 222 into the flow path 22 (see arrow A4). This allows the object in the container 33 to be cooled without temperature unevenness.

[0028] Fig. 7 is a perspective view showing the case 113. In Fig. 7, some of the configuration of the case 113 is omitted. An object is housed in the case 113. As shown in Figs. 4 to 6, the case 113 is supported by the container 33. That is, when in the closed position, the case 113 is housed in the cooling chamber 13. Also, when in the open position, the case 113 is pulled out from the cooling chamber 13 to the front Y1.

[0029] The case 113 is disposed in front of the air outlet 221 of the cooling chamber 13. The case 113 includes a case body 111 and a lid 112.

[0030] The case body 111 has a recess 1111. The recess 1111 of the case body 111 opens toward the upper side Z1. The recess 1111 includes a bottom wall 111a, a pair of side walls 111f, a front wall 111d, and a rear wall 111e.

[0031] An object is placed on the bottom wall 111a. The pair of side walls 111f extend upward from widthwise ends of the bottom wall 111a. The front wall 111d extends upward from the front end of the bottom wall 111a. The rear wall 111e is located closer to the air outlet 221 than the front wall 111d. The rear wall 111e extends upward from the rear end of the bottom wall 111a. A recess 1111 of the case 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 lid 112 covers the recess 1111. The lid 112 has an inclined portion 114. The inclined portion 114 extends upward from one end in the front-rear direction Y toward the center.

[0033] The case 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 that has entered the cooling chamber is hotter and humider than the air inside the cooling chamber. Therefore, condensation may occur due to the temperature difference. In particular, on the air outlet 221 side of the case 113, the temperature difference between the air in the recess 1111 of the case 113 and the cold air outside the case 113 becomes large, and condensation is more likely to occur. By forming the through hole 120 at the end of the air outlet 221 side of the case 113, the temperature of the air outlet 221 side of the recess 1111 is lowered by the cold air that has flowed into the recess 1111 through the through hole 120 at the end of the air outlet 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 case 113 becomes smaller. Therefore, the occurrence of condensation in the cooling chamber can be suppressed.

[0035] The lid 112 covers the recess 1111 of the case body 111, and the inclined portion 114 of the lid 112 can guide the air upward. Cool air from the air outlet 221 passes through the multiple through holes 120 and flows into the recess 1111 of the case body 111. Note that in Fig. 7, only one through hole 120 is given the reference symbol "120". The multiple through holes 120 are arranged along the left-right direction X.

[0036] 5 to 7, the lid 112 has a trapezoidal shape. That is, the inclined portion 114 of the lid 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 further in the forward 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. As shown in FIG. 7, the first inclined portion 114A includes a front end portion 114E and a rear end portion 114C. The front end portion 114E is located further in the forward direction Y1 than the rear end portion 114C. The rear end portion 114C is located further in the forward direction Y1 than a front end portion 114D of the second inclined portion 114B described later. The rear end portion 114C is located higher than the front end portion 114E. That is, the distance from the bottom wall 111a of the case main body 111 to the first inclined portion 114A becomes shorter as the first inclined portion 114A moves from the rear end portion 114C to the front end portion 114E.

[0038] The second inclined portion 114B is located further in the rear direction Y2 than the first inclined portion 114A. The second inclined portion 114B is located closer to the air outlet 221 than the first inclined portion 114A. The upper surface of the second inclined portion 114B has a flat 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 further in the rear direction Y2 than the rear end portion 114C and is located further in 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 distance from the bottom wall 111a of the case 111 main body to the second inclined portion 114B becomes shorter as the second inclined portion 114B moves from the front end portion 114D to the rear end portion 114F.

[0039] The front end 114D of the second inclined portion 114B and the rear end 114C of the first inclined portion 114A are located at the same height. The rear end 114F is located further rearward in the Y2 direction than the front end 114D. The rear end 114F of the second inclined portion 114B and the front end 114D of the first inclined portion 114A are located at the same height.

[0040] The central side refers to the area between the front end 114E and the rear end 114F. In particular, the central side refers to the area between the rear end 114C and the front end 114D.

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

[0042] In the embodiment, as shown in FIG. 6, when the drawer 3 is pulled out from the cooling chamber 13, the air outside the cooling chamber 13 may be drawn into the cooling chamber 13. The air pressure inside the cooling chamber 13 is lower than the air pressure outside the cooling chamber 13. Air moves from a high air pressure area to a low air pressure area. Therefore, the air from the outside flows into the cooling chamber 13. 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 stagnate at the front side of the case body 111, but moves toward the center side of the case body 111 and moves upward of the case body 111. As a result, the case body 111 can be further prevented from being heated by the warm air outside the cooling chamber 13.

[0043] As shown in FIG. 7, the lid 112 further includes a horizontal portion 118 and a pair of side walls 119 .

[0044] The pair of side walls 119 are disposed on the case body 111. The pair of side walls 119 are located on the left side X1 and right side X2 of the inclined portion 114. The pair of side walls 119 are also located on the left side X1 and right side X2 of the horizontal portion 118. That is, the pair of side walls 119 cover the space between the case body 111 and the inclined portion 114. The pair of side walls 119 also cover the space between the case 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 a recess 1111 of the case body 111 that corresponds to the portion between the first inclined portion 114A and the second inclined portion 114B.

[0046] The horizontal portion 118 connects the rear end 114C of the first inclined portion 114A and the front end 114D of the second inclined portion 114B. Therefore, the horizontal portion 118 covers from the rear end 114C of the first inclined portion 114A to the front end 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 inside of the case 113 between the rear end 114C and the front end 114D.

[0047] The case 113 further includes an area 223 to which cool air is blown from the air outlet 221. The cool air from the air outlet 221 is blown toward the case 113 in the forward direction Y1 as shown by the arrow in Fig. 7. The area 223 is provided across the lid 112 and the rear wall 111e. Specifically, the area 223 is located further forward in the Y1 direction than the first inclined portion 114A of the lid 112 and on the upper Z1 side of the rear wall 111e.

[0048] Through hole 120 is formed in region 223 when case 113 is placed in cooling chamber 13. This allows cool air to be blown toward through hole 120. As a result, a larger amount of cool air can be made to flow into recess 1111 compared to a case in which cool air is not blown toward through hole 120, and a rise in temperature of recess 1111 can be suppressed.

[0049] The through-hole 120 has an elongated shape that extends along the direction of flow of cool air from the air outlet 221 when the case 113 is placed in the cooling chamber 13. Therefore, the through-hole 120 has a function of rectifying the flow of cool air. As a result, the cool air easily flows into the inside of the case 113.

[0050] At least a portion of through-hole 120 is formed in lid 112. Specifically, through-hole 120A is provided in lid 112. When through-hole 120A is provided in lid 112 located above case body 111, air inside case 113 that is warmer than cold air can easily escape through through-hole 120A.

[0051] The through hole 120A reaches the edge 112g on the air outlet 221 side of the lid 112. In other words, the through hole 120A is a slit extending from the edge 112g on the air outlet 221 side along the forward direction Y1. When the through hole 120A is shaped to reach the edge 112g, cool air also flows into the inside of the case 113 from the edge 112g, making it easier to make a larger amount of cool air flow into the inside of the case 113. Furthermore, when the through hole 120A is shaped to reach the edge 112g, manufacturing is easier than when a hole is formed whose entire periphery is surrounded by a member, and the amount of raw material can be reduced, resulting in lower manufacturing costs.

[0052] A through hole 120B is provided in the rear wall 111e. The through hole 120B reaches an edge 111g of the rear wall 111e in the upper Z1 direction. In other words, the through hole 120B is a slit that extends from the edge 111g along the lower Z2 direction.

[0053] In a state in which 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. Note that only one of the through hole 120A and the through hole 120B may be provided.

[0054] 7, the lid 112 of this embodiment has another through hole H formed in a region forward of the region 223 in which the through hole 120 is formed. The warm air in the case 113 is pushed upward Z1 by the cool air that has flowed into the case 113 through the through hole 120, and rises toward the lid 112. As a result, the warm air is easily discharged from the through hole H.

[0055] Through hole H penetrates between the inside and outside of case 113. Specifically, a plurality of through holes H are formed in lid 112. Note that in FIG. 7, only one through hole is given the reference symbol "H". The plurality of through holes H are arranged from first inclined portion 114A to second inclined portion 114B. The opening area of ​​through hole 120 is larger than the opening area of ​​through hole H. This promotes the inflow of cool air from through hole 120.

[0056] Specifically, first inclined portion 114A has a plurality of through holes HA. Through holes HA are formed from front end portion 114E of first inclined portion 114A to rear end portion 114C of first inclined portion 114A. Inside case 113, heated air moves along first inclined portion 114A. Then, the heated air is discharged to the outside of case 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 case 113, the heated air moves along the second inclined portion 114B. Then, the heated air is discharged to the outside of the case 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 case 113, the heated air moves along the first inclined portion 114A toward the rear end portion 114C of the first inclined portion 114A. In the case 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 to the horizontal portion 118. Therefore, the heated air is discharged to the outside of the case 113 from the through holes HC of the horizontal portion 118.

[0059] 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 this is not limited thereto. For example, the through hole H may be disposed in 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 in the horizontal portion 118.
