Description

Embodiments of this invention relate to refrigerators.

For example, as described in Patent Document 1, a cold air outlet is formed in the storage compartment of a refrigerator. Cold air generated by the cooler is blown from the outlet into the storage compartment to cool it. Because the cold air blown from the outlet is at a lower temperature than the air in the storage compartment, frost is likely to form around the outlet. If frost forms around the outlet, the circulation of cold air in the storage compartment may be hindered, potentially preventing proper cooling of the compartment.

Japanese Patent Publication No. 2010-230218

Therefore, the object of the present invention is to provide a refrigerator that can suppress frost formation on the periphery of the air outlet from which cold air is blown into the storage compartment.

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. Furthermore, unless otherwise specified, right, left, up, down, front, back, rear, 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.

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

The space above the insulated partition wall 3 is a refrigerated space cooled to a refrigeration temperature range (e.g., 1-5°C). The refrigerated space above the insulated partition wall 3 is further divided vertically by a partition plate 4. A refrigerator compartment 10 is provided above the partition plate 4, and a vegetable compartment 11 is provided below the partition plate 4.

The refrigerator compartment 10 is equipped with multiple shelves 5. Below the lowest shelf 5 is a chilled compartment, which maintains a particularly low temperature within the refrigerator compartment 10. The front opening of the refrigerator compartment 10 is provided with a hinged, pivotally-supported, rotating refrigerator door 15. The front of the refrigerator door 15 is equipped with an operation display unit 6 that receives settings from the user and displays the settings status of the refrigerator 1.

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 the storage container 20 are fixed to the inside of the vegetable compartment door 16, and the storage container 20 is pulled out of the compartment when the door is opened.

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

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.

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. The storage container 21 is held in place by these support frames, and the storage container 21 is designed to be pulled out of the compartment when the door is opened.

As shown in Figures 1 and 2, the second freezer compartment 14 is equipped with three storage containers arranged vertically: a lower container 100, a middle container 101, and an upper container 102. A container support (not shown) supporting the lower container 100 is connected to the rear of the door 19. The configuration allows the lower container 100 and the middle container 101 (supported on its upper surface by the lower container 100) to be pulled out of the compartment when the door is opened.

A cooling unit cover 24 is provided at the rear of the storage compartments (refrigerator compartment 10 and vegetable compartment 11) in the refrigerated temperature zone. A cooling unit compartment 33 and a duct 34 are separated between the cooling unit cover 24 and the rear of the refrigerator body 2. The cooling unit compartment 33 houses a cooling unit 30, a cooling fan 31, and a drainpipe 32. The cooling unit 30 cools the air in the cooling unit compartment 33 to generate cold air, and the cooling fan 31 supplies this cold air to the refrigerator compartment 10 and vegetable compartment 11 via the duct 34, thereby cooling the food stored in the refrigerator compartment 10 and vegetable compartment 11.

A flow path assembly 50 is provided at the rear of the storage compartments in the freezing temperature range (ice-making compartment 12, first freezing compartment 13, and second freezing compartment 14). Between the flow path assembly 50 and the rear of the refrigerator body 2 is a refrigeration cooler compartment 42 housing a refrigeration cooler 38, a refrigeration blower 39, and a drainpipe 41. The refrigeration cooler 38 cools the air in the refrigeration cooler compartment 42 to generate cold air, and the generated cold air is supplied by the refrigeration blower 39 to the ice-making compartment 12, first freezing compartment 13, and second freezing compartment 14 via flow paths 63, 64, and 65 formed in the flow path assembly 50. The specific configuration of the flow path assembly 50 will be described in detail later.

The refrigerator cooler 30 and the refrigerator cooler 38, together with the compressor 44, condenser (not shown), and switching valve (not shown) housed in the machine room 36, constitute a refrigeration cycle. In the refrigeration cycle, refrigerant discharged from the compressor 44 is supplied to either the refrigerator cooler 30 or the refrigerator cooler 38 via the switching valve. This cools the refrigerator cooler 30 or the refrigerator cooler 38 to a predetermined temperature.

Furthermore, a control unit 45, consisting of a control board on which a microcomputer and other components for controlling the refrigerator 1 are mounted, is provided on the outside of the refrigerator body 2 (the exterior side of the interior), for example, on the upper rear surface of the ceiling wall of the refrigerator body 2.

(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 Figure 2.

The lower container 100 is the lowest of the three containers arranged in the second freezer compartment 14. The lower container 100 is a bottomed, open-topped box-shaped structure enclosed by a front wall, left and right side walls, and a rear wall 100a. Compared to the other containers 101 and 102 in the second freezer compartment 14, the lower container 100 has a greater storage depth and is the largest in the vertical direction.

The rear wall 100a of the lower container 100 is designed to have a lower rise 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 itself and the bottom 101a of the upper middle container 101. The lower container 100 is designed to draw in cold air through the lower opening 100b. In other words, the lower opening 100b functions as a cold air introduction point, drawing cold air into the lower container 100.

The middle container 101, located above the lower container 100, is a bottomed, box-shaped structure with an upward-opening structure, enclosed by a front wall, left and right side walls, and a rear wall. It is positioned below the bottom 102a of the upper container 102, at a distance from the bottom.

The rear wall 101b of the middle container 101 has a middle opening 101c recessed downwards from the upper end in the center in the width direction. 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 draw in cold air through the middle opening 101c. In other words, the middle opening 101c functions as a cold air introduction point that draws cold air into the middle container 101.

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

The upper container 102 is supported by legs (not shown) on the left and right side walls, which rest 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.

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

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.

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 opening to the ice-making compartment 12, an outlet 56 opening to the first freezer compartment 13, and outlets 57, 58, 59, 60, 61, and 62 opening to the second freezer compartment 14. Of the outlets 57, 58, 59, 60, 61, and 62 opening to the second freezer compartment 14, outlets 57, 59, and 62 primarily function as internal cooling outlets supplying cold air to the second freezer compartment 14 for cooling, while outlets 58, 60, and 61 primarily function as condensation suppression outlets to prevent condensation from forming on the periphery of outlets 59 and 62.

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 extending 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, 62 and the protruding passage 65 will be described later.

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 rear of the refrigerator body 2. The return duct 80 opens at the lower rear of the second freezer compartment 14 and draws in air from the second freezer compartment 14, returning it to the refrigeration unit compartment 42.

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.

Between the front member 51 and the rear member 52, there is an ice-making channel 66 (see Figure 3), a first refrigeration channel 63, a second refrigeration channel 64, and a protruding channel 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 channels 63, 64, and 65.

The ice-making passage 66 is a passage connecting 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 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.

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

The second refrigeration passage 64 is a passage connecting the outlet side of the refrigeration fan 39 to the outlet 57 that opens into the second freezing chamber 14. A portion of the cold air blown out from the refrigeration fan 39 passes through the second refrigeration passage 64 and is supplied from the outlet 57 into the upper container 102 housed in the second freezing chamber 14.

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, while the remainder flows into the protruding channel 65.

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.

(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.

The protruding airflow channel 65 extends diagonally downward and forward, moving away from the rear of the second freezer chamber 14 as it extends 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.

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 into the interior of the middle container 101 through the middle opening 101c.

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 passage 65. The first upstream outlet 58 is an opening provided in the front member 51 that communicates with the protruding passage 65 and supplies cold air to the outer edge 59a of the first downstream outlet 59.

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 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 channel). As a result, the first upstream outlet 58, which opens in a direction away from the central axis L of the protruding channel 65, is formed between the first upstream outlet forming portion 65a and the outer surface portion 65b of the first intermediate channel. The cold air blown out from the first upstream outlet 58 flows along the outer surface portion 65b of the intermediate section of the first flow path and is supplied to the outer edge portion 59a of the first downstream outlet 59.

The first upstream air outlet 58 is preferably positioned opposite the rear wall of the middle container 101 housed in the second freezer compartment 14, and offset from the position opposite the middle opening 101c and the direction of cold air discharge.

The second downstream outlet 62 is located at the tip of the protruding channel 65, facing 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 towards the lower opening 100b and supplied to the interior of the lower container 100 through the lower opening 100b.

Upstream from the second downstream outlet 62 in the direction of cold air flow in the protruding channel 65, multiple 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 that communicate with the protruding channel 65 and supply cold air to the outer edge 62a of the second downstream outlet 62.

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 in a direction 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 intermediate section of the second flow path and is supplied to the outer edge portion 62a of the second downstream outlet 62.

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. The cold air blown out from this third upstream outlet 60 flows along the second upstream outlet forming portion 65c, passes through the outer edge 61a of the second upstream outlet 61, flows along the outer surface portion 65d of the intermediate part of the second flow path, and is supplied to the outer edge 62a of the second downstream outlet 62.

Furthermore, it is preferable that the first upstream outlet 58, the second upstream outlet 61, and the third upstream outlet 60 have 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).

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. Similarly, 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.

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 internal cooling outlets. 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 flow path intermediate portion) 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.

In this manner, when the shorter lengths of the condensation suppression outlets 58, 60, and 61 are shorter than the shorter lengths 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 compartment. This allows the air to be forcefully directed at areas where condensation should be suppressed, such as the periphery of the internal cooling outlets 59 and 62, thereby suppressing condensation formation or blowing away any condensed water that does occur.

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

Furthermore, the ratio of the length of the internal cooling outlets 59 and 62 in the short direction to the length of the internal cooling 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 internal cooling outlets 58, 60, and 61 in the short direction is preferably about 1.5 mm to 3 mm. If the length of the internal cooling outlets 59 and 62 in the short direction is 25 mm, the length of the internal cooling outlets 58, 60, and 61 in the short direction is preferably about 2.5 mm to 5 mm.

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.

(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.

In this embodiment of the refrigerator 1, 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, thereby expanding the volume of the second freezer compartment 14 of the refrigerator 1.

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, have elongated, slit-shaped openings, the air velocity blown out from these outlets 58, 61, and 60 increases, allowing for reliable blowing away of condensation water generated around the periphery of the first downstream outlet 59 and the second downstream outlet 62.

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. This reduces condensation by allowing air to hit the outer surface portions 65b and 65d of the first and second intermediate flow path, and also allows any condensed water that does occur to be blown away, thus reducing frost formation.

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. Furthermore, 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.

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 airflow velocity 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 airflow 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 condensation or blowing away any condensed water that has formed.
