Background Art

[0002] For example, as described in Patent Document 1, an air outlet for cold air is formed in a storage chamber of a refrigerator. The cold air generated by a cooler blows out from the air outlet into the storage chamber to cool the storage chamber. Since the cold air blown out from the air outlet has a lower temperature than the air in the storage chamber, frosting is likely to occur around the air outlet. When frosting occurs around the air outlet, the circulation of the cold air in the storage chamber may be hindered, and there is a possibility that the storage chamber cannot be cooled normally.

[Figure 5] Front view of the refrigerator in Figure 1, with the door omitted. [Modes for carrying out the invention]

[0007] Embodiments will be described with reference to the drawings. The following embodiments are illustrative and the scope of the invention is not limited thereto. The following embodiments can be carried out in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. The following embodiments and their variations are included in the scope of the invention as described in the claims and its equivalents.

[0008] In the following explanation, left-right, front-back, and up-down directions refer to the directions when viewing the refrigerator from the front, with the left-right direction corresponding to the width of the refrigerator. Also, unless otherwise specified, right, left, up, down, front, back, far, back, and front refer to the position or side of the refrigerator when viewed from the front, and for the refrigerator door, it refers to the position or side when the door is closed and viewed from the front.

[0009] (1) Configuration of Refrigerator 1 As shown in Figure 1, the refrigerator 1 according to this embodiment includes a refrigerator body 2 consisting of an insulated box that opens to the front. The refrigerator body 2 is constructed with an insulating material such as vacuum insulation material or foam insulation material in the insulating space formed between the outer box made of steel plate and the inner box made of synthetic resin. The refrigerator body 2 has multiple storage spaces inside the inner box, and the storage spaces are divided vertically by an insulating partition wall 3.

[0010] The space above the insulated partition wall 3 is a refrigerated space cooled to a refrigeration temperature range (for example, 1-5°C). The refrigerated space partitioned above the insulated partition wall 3 is further divided vertically by a partition plate 4, with a refrigerator compartment 10 provided above the partition plate 4 and a vegetable compartment 11 provided below the partition plate 4.

[0011] The refrigerator compartment 10 is equipped with multiple shelves 5. Below the lowest shelf 5 is a chilled compartment, which is kept at a particularly low temperature within the refrigerator compartment 10. The front opening of the refrigerator compartment 10 is equipped with a hinged, pivotable refrigerator door 15. On the front of the refrigerator door 15 is an operation display unit 6 that receives settings from the user for the refrigerator 1 and displays the settings status of the refrigerator 1.

[0012] The front opening of the vegetable compartment 11 is closed by a pull-out vegetable compartment door 16. A pair of left and right support frames for holding storage containers 20 are fixed to the inside of the vegetable compartment door 16, and the storage containers 20 are pulled out of the compartment when the door is opened.

[0013] The space below the insulated partition wall 3 is a freezing space cooled to a freezing temperature range (for example, below -17°C). Within the freezing space, an ice-making room 12 equipped with an automatic ice maker and a first freezing room 13 are located side by side, and below them, separated by a partition plate 7, is a second freezing room 14.

[0014] The openings of the ice-making compartment 12, the first freezer compartment 13, and the second freezer compartment 14 are closed off by pull-out doors 18 and 19, similar to the vegetable compartment 11.

[0015] A pair of left and right support frames are fixed to the back side of the doors 18 provided in the ice-making compartment 12 and the first freezer compartment 13, and the storage container 21 is held in place by the support frames, and the storage container 21 is pulled out of the compartment when the door is opened.

[0016] As shown in FIGS. 1 and 2, in the second freezer compartment 14, three storage containers consisting of a lower container 100, a middle container 101, and an upper container 102 are provided vertically side by side. A container support (not shown) for supporting the lower container 100 is connected to the back surface portion of the door 19, and the lower container 100 and the middle container 101 supported on the upper surface of the lower container 100 are configured to be pulled out of the cabinet along with the door opening operation.

[0017] A cooler cover 24 is provided at the rear of the storage compartments (refrigerator compartment 10 and vegetable compartment 11) in the refrigerating temperature zone. A refrigerating cooler chamber 33 and a duct 34 are partitioned between the cooler cover 24 and the back surface of the refrigerator body 2. The refrigerating cooler chamber 33 houses a refrigerating cooler 30, a refrigerating blower 31, and a drain gutter 32. The refrigerating cooler 30 cools the air in the refrigerating cooler chamber 33 to generate cold air, and supplies the generated cold air to the refrigerator compartment 10 and the vegetable compartment 11 through the duct 34 by the refrigerating blower 31, thereby cooling the food stored in the refrigerator compartment 10 and the vegetable compartment 11.

[0018] A flow path assembly 50 is provided at the rear of the storage compartments (ice making compartment 12, first freezer compartment 13, and second freezer compartment 14) in the freezing temperature zone. A freezing cooler chamber 42 for housing a freezing cooler 38, a freezing blower 39, and a drain gutter 41 is partitioned between the flow path assembly 50 and the back surface of the refrigerator body 2. The freezing cooler 38 cools the air in the freezing cooler chamber 42 to generate cold air, and supplies the generated cold air to the ice making compartment 12, the first freezer compartment 13, and the second freezer compartment 14 in the freezing temperature zone through flow paths 63, 64, and 65 formed in the flow path assembly 50 by the freezing blower 39. The specific configuration of the flow path assembly 50 will be described in detail later.

[0019] The refrigerating cooler 30 and the freezing cooler 38 constitute a refrigeration cycle together with a compressor 44, a condenser (not shown), and a switching valve (not shown) housed in the machine room 36. In the refrigeration cycle, the refrigerant discharged from the compressor 44 is supplied to one of the refrigerating cooler 30 and the freezing cooler 38 by the switching valve. Thereby, one of the refrigerating cooler 30 and the freezing cooler 38 to which the refrigerant is supplied is cooled to a predetermined temperature.

[0020] Further, on the outer side of the refrigerator body 2 (outside the refrigerator), for example, at the rear part of the upper surface of the ceiling wall of the refrigerator body 2, a control unit 45 composed of a control board on which a microcomputer for controlling the refrigerator 1 and the like is mounted is provided.

[0021] (2) Lower container 100, middle container 101, and upper container 102 Next, the lower container 100, middle container 101, and upper container 102 provided in the second freezer compartment 14 will be described with reference to FIG. 2.

[0022] The lower container 100 is the container arranged at the lowermost position among the three containers arranged in the second freezer compartment 14. The lower container 100 has a bottomed box shape that is open upward and is surrounded by a front wall, left and right side walls, and a rear wall 100a. The lower container 100 has a greater accommodation depth than the other containers 101 and 102 arranged in the second freezer compartment 14 and is the largest in the vertical direction.

[0023] The rear wall 100a of the lower container 100 is provided with a lower rising height from the bottom surface compared to the left and right side walls of the lower container 100. The rear wall 100a of the lower container 100 forms a lower opening 100b between it and the bottom 101a of the middle container 101 arranged above. The lower container 100 is configured to take in cold air from the lower opening 100b into the interior. That is, the lower opening 100b functions as a cold air introduction part for taking in cold air into the lower container 100.

[0024] The middle container 101 provided above the lower container 100 has a bottomed box shape that is open upward and is surrounded by a front wall, left and right side walls, and a rear wall, and is arranged at an interval below the bottom 102a of the upper container 102.

[0025] The rear wall 101b of the middle container 101 has a middle opening 101c in the center in the width direction that is recessed downward from the upper end. The area above the middle opening 101c is partitioned by the bottom 102a of the upper container 102. The middle container 101 is designed to take in cold air from the middle opening 101c. In other words, the middle opening 101c functions as a cold air introduction section that takes in cold air into the middle container 101.

[0026] The upper container 102, located above the middle container 101, is a bottomed box-shaped structure with an upward opening, surrounded by a front wall, left and right side walls, and a rear wall, and is positioned as the uppermost container among those arranged in the second freezer compartment 14.

[0027] The upper container 102 is supported by legs (not shown) on the left and right side walls, which are mounted on rails extending in the front-to-back direction from the left and right side walls of the second freezer compartment 14. The upper container 102 is installed in the second freezer compartment 14 so that it can be pulled out of the compartment independently of the lower container 100 and the middle container 101 by sliding its legs along the rails in the front-to-back direction.

[0028] (3) Flow channel assembly 50 Next, the flow channel assembly 50 will be described with reference to Figures 2 to 5.

[0029] As shown in Figure 3, the flow path assembly 50 comprises a front member 51, a rear member 52 provided behind the front member 51, and a heat insulating molded body 53 provided between the front member 51 and the rear member 52.

[0030] The front member 51 is a plate-shaped member provided at a distance in front of the rear member 52, and constitutes the back surface of the ice-making compartment 12, the first freezer compartment 13, and the second freezer compartment 14. As shown in Figure 2, the front member 51 is provided with an outlet 55 that opens into the ice-making compartment 12, an outlet 56 that opens into the first freezer compartment 13, and outlets 57, 58, 59, 60, 61, and 62 that open into the second freezer compartment 14. Of the outlets 57, 58, 59, 60, 61, and 62 that open into the second freezer compartment 14, outlets 57, 59, and 62 mainly function as internal cooling outlets that supply cold air to the second freezer compartment 14 to cool the inside of the second freezer compartment 14, while outlets 58, 60, and 61 mainly function as condensation suppression outlets that suppress the occurrence of condensation on the periphery of outlets 59 and 62.

[0031] The air outlet 57 is located above the rear wall 102b of the upper container 102 housed in the second freezer compartment 14. The cold air blown out from the air outlet 57 is supplied into the upper container 102 through the top opening. Air outlets 58, 59, 60, 61, and 62 are located in a protruding passage 65 that extends forward from the rear of the second freezer compartment 14. In this embodiment, two protruding passages 65 are provided spaced apart in the width direction of the refrigerator. The detailed configuration of the air outlets 58, 59, 60, 61, and 62 and the protruding passage 65 will be described in detail later.

[0032] The rear member 52 is a plate-shaped member that covers the front of the refrigeration unit 38, and a refrigeration fan 39 is attached to a mounting hole 54 located above the refrigeration unit 38. The lower end of the rear member 52 forms a return duct 80 between it and the back of the refrigerator body 2. The return duct 80 opens to the lower rear of the second freezer compartment 14 and draws in air from the second freezer compartment 14 and returns it to the refrigeration unit compartment 42.

[0033] The heat-insulating molded body 53 is, for example, made by molding foamed plastic into a predetermined shape, and is fixed by being sandwiched between the front member 51 and the rear member 52.

[0034] Between the front member 51 and the rear member 52, there is an ice-making passage 66 (see Figure 3), a first refrigeration passage 63, a second refrigeration passage 64, and a protruding passage 65. Cold air blown from the refrigeration fan 39 is supplied to the outlets 55, 56, 57, 58, 59, 60, 61, and 62 via the respective passages 63, 64, and 65.

[0035] The ice-making passage 66 is a passage that connects the outlet side of the refrigeration fan 39 to the outlet 55 that opens into the ice-making chamber 12. A portion of the cold air blown out from the refrigeration fan 39 passes through the ice-making passage 66 and is supplied to the ice-making chamber 12 from the outlet 55.

[0036] The first refrigeration passage 63 is a passage that connects the outlet side of the refrigeration fan 39 to the outlet 56 that opens into the first freezer chamber 13. A portion of the cold air blown out from the refrigeration fan 39 is supplied to the first freezer chamber 13 from the outlet 56 through the first refrigeration passage 63.

[0037] The second refrigeration passage 64 is a passage that connects the outlet side of the refrigeration fan 39 to the outlet 57 that opens into the second freezer chamber 14. A portion of the cold air blown out from the refrigeration fan 39 is supplied through the second refrigeration passage 64 to the inside of the upper container 102 housed in the second freezer chamber 14 via the outlet 57.

[0038] Furthermore, the second refrigeration channel 64 has a protruding channel 65 connected to it on the downstream side in the direction of cold air flow, forming a continuous channel with the protruding channel 65. As a result, a portion of the cold air flowing through the second refrigeration channel 64 is blown out from the outlet 57 into the second refrigeration chamber 14, and the remainder flows into the protruding channel 65.

[0039] The ice-making channel 66, the first refrigeration channel 63, and the second refrigeration channel 64 described above are formed in an insulating molded body 53, and the storage chamber side (front side) is covered by the insulating molded body 53. Dampers may be provided in the middle of the ice-making channel 66, the first refrigeration channel 63, and the second refrigeration channel 64 to allow adjustment of the amount of cold air flowing through each channel.

[0040] (4) Outflow channel 65 As shown in Figures 2 and 5, the protruding channel 65 is a channel that is not covered by the heat insulating molded body 53 formed by the front member 51 and the rear member 52. In other words, the protruding channel 65 is covered on the front side by the front member 51 and on the rear side by the rear member 52. The protruding channel 65 and the outlets 58, 59, 60, 61, and 62 are located downstream of the heat insulating molded body 53 in the flow direction of cold air in the channel composed of the second refrigeration channel 64 and the protruding channel 65.

[0041] The protruding airflow channel 65 extends diagonally downward and forward, moving away from the rear of the second freezer chamber 14 as it goes downward. On the front side of this protruding airflow channel 65, as shown in Figure 5, the first upstream outlet 58, the first downstream outlet 59, the third upstream outlet 60, the second upstream outlet 61, and the second downstream outlet 62 are provided in order from the upstream side to the downstream side in the direction of cold air flow.

[0042] The first downstream outlet 59 is provided on the front member 51 so as to face the middle opening 101c of the middle container 101 housed in the second freezer chamber 14. A portion of the cold air flowing through the protruding channel 65 is blown out from the first downstream outlet 59 toward the middle opening 101c and supplied to the inside of the middle container 101 through the middle opening 101c.

[0043] The first upstream outlet 58 is provided on the front member 51b so as to be located upstream of the first downstream outlet 59 in the direction of cold air flow in the protruding channel 65. The first upstream outlet 58 is an opening provided on the front member 51 so as to communicate with the protruding channel 65 and supplies cold air to the outer edge 59a of the first downstream outlet 59.

[0044] Specifically, the front member 51 that constitutes the outer surface of the protruding channel 65 is provided with a step so that the downstream side of the protruding channel 65 narrows, and the first upstream outlet 58 is provided in this stepped portion. In other words, the front member 51 is provided at a position away from the central axis L of the protruding channel 65 (in this embodiment, a position shifted diagonally upward and forward) such that the portion 65a upstream of the first upstream outlet 58 in the direction of cold air flow (hereinafter referred to as the first upstream outlet forming portion) is located at a position away from the central axis L of the protruding channel 65, compared to the outer surface portion 65b of the first intermediate section of the first channel provided between the first upstream outlet 58 and the first downstream outlet 59 (i.e., the portion 65b of the front member 51 that demarcates the front surface of the first intermediate section of the first channel) so that the channel widens. As a result, the first upstream outlet 58 is formed between the first upstream outlet forming portion 65a and the outer surface portion 65b of the first intermediate section of the first channel, opening in a direction away from the central axis L of the protruding channel 65. The cold air blown out from the first upstream outlet 58 flows along the outer surface portion 65b of the middle section of the first flow path and is supplied to the outer edge portion 59a of the first downstream outlet 59.

[0045] The first upstream outlet 58 is preferably positioned so as to face the rear wall of the middle container 101 housed in the second freezer chamber 14, and is offset from the position facing the middle opening 101c and the direction of cold air discharge.

[0046] The second downstream outlet 62 is located at the tip of the protruding channel 65 so as to face the lower opening 100b of the lower container 100 housed in the second freezer chamber 14. Cold air flowing through the tip of the protruding channel 65 is blown out from the second downstream outlet 62 toward the lower opening 100b and supplied into the interior of the lower container 100 through the lower opening 100b.

[0047] Upstream from the second downstream outlet 62 in the direction of cold air flow in the protruding channel 65, a plurality of upstream outlets (in this embodiment, the second upstream outlet 61 and the third upstream outlet 60) are provided at intervals in the direction of cold air flow. The second upstream outlet 61 and the third upstream outlet 60 are openings provided in the front member 51 so as to communicate with the protruding channel 65 and supply cold air to the outer edge 62a of the second downstream outlet 62.

[0048] Specifically, the portion of the front member 51 that constitutes the outer surface downstream of the first downstream outlet 59 of the protruding flow path 65 has two steps so that the downstream side of the protruding flow path 65 narrows, and the second upstream outlet 61 and the third upstream outlet 60 are provided in these stepped portions. In other words, the front member 51 is positioned so that the portion upstream of the second upstream outlet 61 in the direction of cold air flow (hereinafter referred to as the second upstream outlet forming portion) 65c is located away from the central axis L of the protruding flow path 65, so that the flow path widens compared to the outer surface portion 65d of the second intermediate flow path provided between the second upstream outlet 61 and the second downstream outlet 62. As a result, the second upstream outlet 61, which opens away from the central axis L of the protruding flow path 65, is formed between the second upstream outlet forming portion 65c and the outer surface portion 65d of the second intermediate flow path. The cold air blown out from the second upstream outlet 61 flows along the outer surface portion 65d of the middle section of the second flow path and is supplied to the outer edge portion 62a of the second downstream outlet 62.

[0049] Furthermore, in the front member 51, the portion 65e upstream of the third upstream outlet 60 in the direction of cold air flow (hereinafter referred to as the third upstream outlet forming portion) is positioned away from the central axis L of the protruding flow path 65 so that the flow path is wider compared to the second upstream outlet forming portion 65c. As a result, a third upstream outlet 60 is formed between the third upstream outlet forming portion 65e and the second upstream outlet forming portion 65c, opening in a direction away from the central axis L of the protruding flow path 65. Cold air blown out from this third upstream outlet 60 flows along the second upstream outlet forming portion 65c, passes through the outer edge portion 61a of the second upstream outlet 61, flows along the outer surface portion 65d of the middle section of the second flow path, and is supplied to the outer edge portion 62a of the second downstream outlet 62.

[0050] Furthermore, it is preferable that the first upstream outlet 58, the second upstream outlet 61, and the third upstream outlet 60 are slit-shaped openings, that is, elongated notched openings that are long in one direction (the left-right direction perpendicular to the direction away from the central axis L in this embodiment) and short in the other direction perpendicular to the same direction (the up-down direction away from the central axis L of the protruding flow path 65 in this embodiment).

[0051] In the longitudinal direction (left-right direction) of the first upstream outlet 58, it is preferable that the length of the first upstream outlet 58 is equal to or greater than the length of the first downstream outlet 59, and in the longitudinal direction (left-right direction) of the second upstream outlet 61 and the third upstream outlet 60, it is preferable that the lengths of the second upstream outlet 61 and the third upstream outlet 60 are equal to or greater than the length of the second downstream outlet 62.

[0052] Furthermore, the lengths in the shorter direction (vertical direction in this embodiment) of the first upstream outlet 58, second upstream outlet 61, and third upstream outlet 60, which function as condensation suppression outlets, may be shorter than the lengths in the shorter direction of the first downstream outlet 59 and second downstream outlet 62, which function as cooling outlets inside the chamber. In other words, the vertical width of the first upstream outlet 58 (the distance between the first upstream outlet forming portion 65a and the outer surface portion 65b of the first intermediate flow path) may be smaller than the vertical width of the first downstream outlet 59, and the vertical widths of the second upstream outlet 61 and third upstream outlet 60 may be smaller than the vertical width of the second downstream outlet 62.

[0053] In this way, when the shorter length of the condensation suppression outlets 58, 60, and 61 is shorter than the shorter length of the internal cooling outlets 59 and 62, it is possible to increase the airflow velocity of the cold air blown out from the condensation suppression outlets 58, 60, and 61 while ensuring the necessary airflow to cool the storage room, thereby forcefully directing the airflow to areas where condensation should be suppressed, such as the periphery of the internal cooling outlets 59 and 62, thereby suppressing the occurrence of condensation or blowing away any condensed water that has occurred.

[0054] The sizes of the condensation suppression outlets 58, 60, 61 and the internal cooling outlets 59, 62 are adjusted as appropriate depending on the size of the second freezer compartment 14 and the capacity of the refrigeration cycle, but the length of the condensation suppression outlets 58, 60, 61 in the shorter direction can be, for example, 1 mm or more and 5 mm or less.

[0055] Furthermore, the ratio of the length of the internal cooling outlets 59 and 62 in the short direction to the length of the condensation suppression outlets 58, 60 and 61 in the short direction is preferably 1 / 10 or more and 1 / 5 or less. For example, if the length of the internal cooling outlets 59 and 62 in the short direction is 15 mm, the length of the condensation suppression outlets 58, 60 and 61 in the short direction is preferably about 1.5 mm to 3 mm, and if the length of the internal cooling outlets 59 and 62 in the short direction is 25 mm, the length of the condensation suppression outlets 58, 60 and 61 in the short direction is preferably about 2.5 mm to 5 mm.

[0056] Furthermore, the length of the condensation suppression outlets 58, 60, and 61 in the shorter direction may be longer than or the same as the length of the internal cooling outlets 59 and 62 in the shorter direction.

[0057] (5) Effects In the refrigerator 1 of this embodiment, the first upstream outlet 58 supplies cold air to the outer edge 59a of the first downstream outlet 59, thereby blowing air around the first downstream outlet 59 to suppress condensation and blow away any condensed water that does occur, making it less likely for frost to form around the first downstream outlet 59. In addition, the second upstream outlet 61 and the third upstream outlet 60 supply cold air to the outer edge of the second downstream outlet 62, thereby blowing air around the second downstream outlet 62 to suppress condensation and blow away any condensed water that does occur, making it less likely for frost to form around the second downstream outlet 62.

[0058] In the refrigerator 1 of this embodiment, since the front side of the protruding channel 65 is not covered by the heat insulating molded body 53, the portion of the protruding channel 65 in the channel assembly 50 can be made thinner, and the volume of the second freezer compartment 14 of the refrigerator 1 can be expanded.

[0059] In the refrigerator 1 of this embodiment, if the first upstream outlet 58, the second upstream outlet 61, and the third upstream outlet 60, which function as condensation suppression outlets, are elongated slit-shaped openings, the air velocity blown out from these outlets 58, 61, and 60 increases, and condensation water generated around the periphery of the first downstream outlet 59 and the second downstream outlet 62 can be reliably blown away.

[0060] In the refrigerator 1 of this embodiment, the cold air blown out from the first upstream outlet 58 flows along the outer surface portion 65b of the first intermediate flow path, and the cold air blown out from the second upstream outlet 61 flows along the outer surface portion 65d of the second intermediate flow path. As a result, condensation is less likely to occur as air blows over the outer surface portion 65b of the first intermediate flow path and the outer surface portion 65d of the second intermediate flow path, and any condensed water that does occur can be blown away, making frost formation less likely.

[0061] In the longitudinal direction of the first upstream outlet 58, if the length of the first upstream outlet 58 is greater than or equal to the length of the first downstream outlet 59, cold air can be supplied to a wide area of ​​the outer edge 59a of the first downstream outlet 59, and condensation water generated on the periphery of the first downstream outlet 59 can be reliably blown away. Also, in the longitudinal direction of the second upstream outlet 61 and the third upstream outlet 60, if the lengths of the second upstream outlet 61 and the third upstream outlet 60 are greater than or equal to the length of the second downstream outlet 62, cold air can be supplied to a wide area of ​​the outer edge 62a of the second downstream outlet 62, and condensation water generated on the periphery of the second downstream outlet 62 can be reliably blown away.

[0062] Furthermore, if the vertical width of the first upstream outlet 58 is smaller than the vertical width of the first downstream outlet 59, or if the vertical width of the second upstream outlet 61 is smaller than the vertical width of the second downstream outlet 62, the wind speed of the cold air blown out from the first upstream outlet 58, the second upstream outlet 61, and the third upstream outlet 60 can be increased while suppressing a decrease in the amount of cold air supplied to the middle container 101 and the lower container 100. This allows the wind to be forcefully directed at areas where condensation should be suppressed, such as the periphery of the first downstream outlet 59 and the second downstream outlet 62, thereby suppressing the occurrence of condensation or blowing away any condensed water that has occurred.
