The refrigerator compartment 6 and vegetable compartment 7 are storage compartments that are cooled to a refrigeration temperature range (e.g., 1 to 4°C) based on the temperature detected by a refrigerator compartment temperature sensor 36 installed on the rear surface of the compartment. The refrigerator compartment 6 and vegetable compartment 7 are separated from each other by a partition plate 11 made of synthetic resin, and air from the refrigerator compartment 6 flows into the vegetable compartment 7 through a communication hole 17 installed at the rear end of the partition plate 11. A pivoting insulated door 6a supported by a hinge is installed at the front opening of the refrigerator compartment 6.

The rear surface of the refrigerator compartment 6 is partitioned by a rear wall member 40 that is provided in front of the inner box back surface 4e with a space in between. Between the rear wall member 40 and the inner box back surface 4e, a first flow path section 24b and a second flow path section 24c that constitute a part of the refrigerator side flow path 24 through which the cold air supplied to the refrigerator compartment 6 flows are formed. In addition, the rear wall member 40 is provided with an operation panel 39 that allows the user to perform various settings such as temperature settings for the refrigerator compartment 6 and the freezer compartment 10, and a refrigerator compartment temperature sensor 36 that detects the temperature inside the refrigerator compartment 6.

The interior space of the refrigerator compartment 6 is provided with multiple shelves 12 spaced apart vertically. The space partitioned vertically by the partition plate 11 and the lowest shelf 12a forms a lower storage chamber 6b for storing pull-out containers such as a water tank 30 and a storage container 14, and the space partitioned above the lowest shelf 12a forms an upper storage chamber 6c in which shelves 12 are provided.

The lower storage compartment 6b is divided in the width direction of the refrigerator by a vertical partition wall 13 arranged against one side wall (left side wall) of the refrigerator compartment 6 (see FIG. 3). A water supply tank 30 and a water supply device 31 are provided in the space between the left side wall of the refrigerator compartment 6 and the vertical partition wall 13. The water supply tank 30 is a pull-out container that is stored at a predetermined position in the front-rear direction by a positioning portion (not shown) provided on the partition plate 11.

A drawer-type storage container 14 is stored in the space between the vertical partition wall 13 and the other side wall (right side wall) of the refrigerator compartment 6. The vertical partition wall 13 is positioned so as to be hidden behind the front part of the storage container 14 as shown in FIG. 3.

In the lower storage chamber 6b, the rear wall member 40 and the housing case 38 located at the rear of the chamber are covered from the front by the water tank 30 and the storage container 14.

The upper storage compartment 6c is the storage compartment located at the top of the refrigerator 1, and when no stored goods are stored in it, the rear wall panel 41 of the rear wall member 40 located at the rear of the upper storage compartment 6c is exposed and visible from the front.

The bottom shelf 12a may be fixed to the left and right side surfaces 4a, 4b of the inner box 4, or may be removably attached to the left and right side surfaces 4a, 4b of the inner box 4.

The ceiling wall of the refrigerator body 2, which forms the ceiling surface of the refrigerator compartment 6, houses a lighting device 80 on the inside that illuminates the interior of the refrigerator compartment 6.

A pull-out insulated door 7a is provided at the front opening of the vegetable compartment 7. A storage container 15 that constitutes a storage container is connected to the back of this insulated door 7a, and the storage container 15 is configured to be pulled out of the compartment when the door is opened.

The freezer compartment 10 is a storage compartment that is cooled to a freezing temperature range (e.g., -10 to -20°C) based on the temperature detected by a freezer compartment temperature sensor 37 installed on the rear side. The vegetable compartment 7 and the freezer compartment 10 are separated from each other by an insulated partition wall 16 with insulating material installed inside. A pull-out insulated door 10a is installed at the front opening of the freezer compartment 10.

As shown in FIG. 1, the freezer compartment 10 has three storage containers arranged vertically, the lower container 100, the middle container 101, and the upper container 102. The lower container 100 is connected to the rear of the insulated door 10a, and is configured so that the lower container 100 and the middle container 101, which is supported on the upper surface of the lower container 100, are pulled out of the freezer when the door is opened.

An ice-making device 105 including an ice tray and ice-release mechanism is provided above the upper container 102, and ice made by the ice-making device 105 falls into the upper container 102 and is stored there. The ice-making device 105, together with a water supply tank 30 and a water supply device 31 provided in the refrigerator compartment 6, constitutes an automatic ice-making device, and water from the water supply tank 30 sucked up by the water supply device 31 is supplied to the ice tray.

At the back of the freezer compartment 10, there is a cooler 21 that generates cold air to cool the storage compartments 6, 7, and 10, and a cooler compartment 23 that houses a cooler fan 22. The cooler compartment 23 is connected to a refrigeration side flow path 24 that supplies the cold air generated by the cooler 21 to the refrigerator compartment 6, a freezer side flow path 26 that supplies the cold air generated by the cooler 21 to the freezer compartment 10, and a return duct 19 that returns the air that has flowed through each storage compartment 6, 7, and 10 to the cooler compartment 23. A refrigeration damper 25 is provided at the connection between the cooler compartment 23 and the refrigeration side flow path 24, and a freezer damper 27 is provided at the connection between the cooler compartment 23 and the freezer side flow path 26.

The refrigeration side flow path 24 is formed by connecting, in order from below, the vegetable compartment flow path 24a provided on the rear surface of the vegetable compartment 7, and the first flow path section 24b and the second flow path section 24c provided at the rear of the refrigerator compartment 6.

The vegetable compartment flow path 24a is positioned such that its widthwise center is shifted toward one widthwise side (the right side in this embodiment) from the widthwise center of the vegetable compartment 7. The vegetable compartment flow path 24a widens in width as it moves upward from the refrigeration damper 25 and is connected to the lower end of the first flow path section 24b.

The first flow path section 24b extends upward from the lower end of the lower storage chamber 6b, extends to a position above the lowest shelf 12a, and is provided at the rear of the lower storage chamber 6b and at the rear of the lower part of the upper storage chamber 6c. The first flow path section 24b is positioned such that its widthwise center is shifted toward one widthwise side (the right side in this embodiment) from the widthwise center of the refrigerator chamber 6.

The upper end of the first flow path section 24b is connected to the second flow path section 24c via an inclined section 24d that is inclined diagonally inward in the width direction (to the left in this embodiment) with respect to the vertical direction. The second flow path section 24c is positioned such that its width direction center is closer to the width direction center of the refrigerator compartment 6 than the width direction center of the first flow path section 24b.

An outlet 18b that opens into the lower storage chamber 6b is provided on the front surface of the first flow path section 24b, and an outlet 18c that opens into the upper storage chamber 6c is provided on the front surface of the second flow path section 24c.

The cooler 21 forms a refrigeration cycle together with a compressor 29 and a condenser housed in a machine chamber 28 formed in the lower back of the refrigerator body 2, and is cooled by the refrigerant discharged from the compressor 29. The cooler 21 cools the air in the cooler chamber 23 to generate cold air for cooling each of the storage chambers 6, 7, and 10.

As shown in FIG. 1, a circuit board storage section 60 is provided at the top of the rear of the refrigerator body 2, which is recessed forward. Inside the circuit board 60 are provided a control circuit board 70 that controls the refrigerator 1 and electrical components 71 such as a reactor.

The control board 70 controls the overall operation of the refrigerator 1 by controlling the opening and closing of the refrigeration damper 25 and the freezing damper 27, the rotation speed of the cooler fan 22, the operating frequency of the compressor 29, and the lighting device 80 based on detection signals input from the various sensors 36, 37 and the operation panel 39 and a control program pre-stored in memory.

In a refrigerator 1 configured in this way, the rotation of the cooler fan 22 and the opening and closing of the refrigeration damper 25 and freezer damper 27 are controlled to supply the cold air generated by the cooler 21 to the refrigerator compartment 6, vegetable compartment 7, and freezer compartment 10 in a switched manner, thereby cooling each of the storage compartments 6, 7, and 10 so that the temperatures detected by the refrigerator compartment temperature sensor 36 and freezer compartment temperature sensor 37 satisfy the specified temperature conditions.

Specifically, when cooling the refrigerator compartment 6 and the vegetable compartment 7, the compressor 29 is driven to lower the temperature of the cooler 21, while the refrigerator damper 25 is opened and the freezer damper 27 is closed, and the cooler fan 22 is driven. As a result, the air cooled by the cooler 21 flows upward through the vegetable compartment flow path 24a, the first flow path section 24b, the inclined section 24d, and the second flow path section 24c, and is supplied to the refrigerator compartment 6 through the air outlets 18b and 18c, cooling the refrigerator compartment 6. The air that has flowed through the refrigerator compartment 6 flows into the vegetable compartment 7 through the communication hole 17 provided in the partition plate 11, cools the inside of the vegetable compartment 7, and is then taken into the return duct 19 through the suction port 19a provided on the back of the vegetable compartment 7, returns to the cooler compartment 23, and is cooled again by heat exchange with the cooler 21.

When cooling the freezer compartment 10, the compressor 29 is driven to lower the temperature of the cooler 21, while the freezer damper 27 is opened and the refrigeration damper 25 is closed, and the cooler fan 22 is driven. As a result, the air cooled by the cooler 21 passes through the freezer side flow path 26 and is supplied to the freezer compartment 10 from the outlet 34, cooling the freezer compartment 10. The air that flows through the freezer compartment 10 is taken into the return duct 19 from the suction port 19b provided on the back of the freezer compartment 10, returns to the cooler compartment 23, and is cooled again by heat exchange with the cooler 21.

In addition, in the refrigerator 1, when the door 6a of the refrigerator compartment 6 is opened, the control board 70 supplies driving power to the lighting device 80 to illuminate the interior of the refrigerator compartment 6.

(2) Refrigerator body 2
Next, the configuration of the refrigerator body 2 will be described.

The inner box 4 is made of a synthetic resin molded body integrally formed by a vacuum molding machine, and has a box-like shape with an open front and an inner box left side 4a, inner box right side 4b, inner box top surface 4c, inner box bottom surface 4d, and inner box back surface 4e.

As shown in Figures 1, 4 and 5, the inner box top surface 4c defines the ceiling surface of the refrigerator compartment 6, and is provided with a lighting device 80. The lighting device 80 can be provided at any position on the inner box top surface 4c. For example, the lighting device 80 can be provided so as to overlap vertically with the front end of the top shelf board 12 provided in the refrigerator compartment 6, the lighting device 80 can be provided so that the light source 83 described below is located forward of the top shelf board 12, or the lighting device 80 can be provided forward of the center of the refrigerator compartment 6 in the front-to-rear direction.

The inner box top surface 4c is an inclined surface that slopes upward as it approaches the front. Specifically, the inner box top surface 4c includes an inner box top surface front portion 4c1 located in front of the lighting device 80 and an inner box top surface rear portion 4c2 located behind the lighting device 80.

The front 4c1 and rear 4c2 of the top surface of the inner box are both inclined upwards as they go forward, but the angle θ1 of the front 4c1 to the horizontal is greater than the angle θ2 of the rear 4c2 to the horizontal (see Figure 5).

The inner box upper surface 4c is provided with a mounting recess 4c3 that is recessed upward toward the thermal insulation space 5 at the mounting position of the lighting device 80. A mounting opening 4c4 penetrates the bottom surface of the mounting recess 4c3.

The peripheral wall of the mounting recess 4c3, which connects the bottom surface of the mounting recess 4c3 to the top surface 4c of the inner box, is inclined toward the inside of the mounting recess 4c3 as it approaches the bottom surface (so that it becomes narrower as it approaches the back of the mounting recess 4c3). In other words, of the peripheral walls of the mounting recess 4c3, the front peripheral wall 4c5, which connects the bottom surface of the mounting recess 4c3 to the front part 4c1 of the top surface of the inner box, is inclined toward the rear as it approaches the bottom surface of the mounting recess 4c3. The rear peripheral wall 4c6, which connects the bottom surface of the mounting recess 4c3 to the rear part 4c2 of the top surface of the inner box, is inclined toward the front as it approaches the bottom surface of the mounting recess 4c3. In this embodiment, the front peripheral wall 4c5 has a larger inclination angle in the vertical direction than the rear peripheral wall 4c6 (see FIG. 4).

The outer box 3 made of steel plate that constitutes the outer shell of the refrigerator body 2 is box-shaped with an opening at the front, and has an outer box left side 3a, outer box right side 3b, outer box top side 3c, outer box bottom side 3d, and outer box back side 3e that face the inner box left side 4a, inner box right side 4b, inner box top side 4c, inner box bottom side 4d, and inner box back side 4e of the inner box 4, respectively. The outer box left side 3a, outer box right side 3b, and outer box top side 3c are formed by bending a single long steel plate into an approximately U-shape. The outer box bottom side 3d and outer box back side 3e are members provided separately from the outer box left side 3a, outer box right side 3b, and outer box top side 3c. A step portion is bent and formed on the outer box bottom side 3d to form the machine room 28.

(3) Illumination device 80
Next, the configuration of the illumination device 80 will be described mainly with reference to FIGS.

The lighting device 80 includes a lighting storage section 81 provided on the insulating space 5 side (upper side) of the mounting recess 4c3 on the inner box top surface 4c, a lighting cover 82 provided below the mounting recess 4c3, and a light source 83 such as an LED.

The lighting storage section 81 is made of a vertically flat dish-shaped member with a storage opening 84 provided below, and a flange 85 protrudes outward from the periphery of the storage opening 84. The lighting storage section 81 is attached to the inner box top surface 4c such that the mounting recess 4c3 provided on the inner box top surface 4c is inserted into the storage opening 84 from below, and the mounting recess 4c3 fits into the insulating space 5 side.

When the lighting storage section 81 is attached to the inner box top surface 4c in this manner, as shown in FIG. 5, the flange 85 comes into contact with the insulating space 5 side of the periphery of the mounting recess 4c3, and the storage opening 84 communicates vertically with the mounting opening 4c4 of the mounting recess 4c3, opening up the lower part of the lighting storage section 81.

A holder 87 is provided inside the lighting storage section 81 to hold a lighting board 86 on which the light source 83 is mounted. A plurality of holders 87 are provided at intervals in the width direction of the refrigerator 1, and hold the lighting board 86 at an angle so that the light emission direction of the light source 83 is tilted backward rather than vertically downward at a position closer to the front than the center of the lighting storage section 81 in the front-to-rear direction.

Inside the lighting storage section 81, a shielding section 88 is provided in front of the holding section 87, and a wiring storage section 96 is provided behind the holding section 87 to store lead wires connected to the lighting board 86. The shielding section 88 is a light-blocking plate-like body that is integral with the lighting storage section 81 and hangs downward. The shielding section 88 is provided over almost the entire lighting storage section 81 along the width direction of the refrigerator 1, and blocks at least a portion of the light emitted from the light source 83 that travels forward.

The lighting cover 82 is a molded body made of highly transparent acrylic resin or the like, and is attached to the mounting recess 4c3 on the upper surface 4c of the inner box. It closes the storage opening 84 of the lighting storage section 81 while diffusing the light from the light source 83 to irradiate it into the refrigerator compartment 6.

The lighting cover 82 has a peripheral wall that protrudes upward from the periphery of the emission surface 90 that faces the light source 83 from above and below, and has a vertically flat dish shape that opens upward.

Specifically, the lower side of the emission surface 90 (the side facing the refrigerator compartment 6) is inclined upward as it goes rearward, and forms an inclined surface with an angle θ3 with respect to the horizontal direction that is greater than the angles θ1, θ2 of the inner box top front part 4c1 and the inner box top rear part 4c2 with respect to the horizontal direction. The upper surface of the emission surface 90 (the side facing the lighting storage section 81) forms an uneven surface with multiple ridges extending in the width direction lined up in the front-to-rear direction, which diffuses the light emitted from the light source 83.

The upper ends of the front protruding surface 91 and the rear protruding surface 92, which protrude from the front and rear ends of the emission surface 90, are provided with locking claws 93 that protrude upward. The locking claws 93 are inserted from below into the mounting openings 4c4 of the mounting recesses 4c3 provided on the inner box top surface 4c, and lock into the locking portions 94 provided on the lighting storage section 81. This fixes the lighting cover 82 to the inner box top surface 4c so as to close the mounting openings 4c4 of the mounting recesses 4c3.

When the lighting cover 82 is attached to the mounting recess 4c3 of the inner box top surface 4c, the front protruding surface 91 protrudes downward from the front part 4c1 of the inner box top surface. This front protruding surface 91 may be provided with a colored layer 91a colored in a metallic color such as silver or the same color as the inner box 4, and may be inclined so that it approaches the front as it goes upward. The colored layer 91a can be formed on the front protruding surface 91 by any method, such as by attaching a separate sheet, by hot stamping or painting, or by plating or vapor deposition.

When the lighting cover 82 is fixed to the mounting recess 4c3 on the inner box top surface 4c, the shielding portion 88 is disposed between the lighting board 86 held by the holding portion 87 and the forward protruding surface 91, and the shielding portion 88 covers the rear side of the forward protruding surface 91 across almost the entire width.

The rear protruding surface 92 protrudes downward from the rear part 4c2 of the inner box top surface when the lighting cover 82 is attached to the mounting recess 4c3 of the inner box top surface 4c. It is preferable that the amount of protrusion from the rear part 4c2 of the inner box top surface (the rear end of the mounting recess 4c3) to the bottom end of the rear protruding surface 92 is smaller than the amount of protrusion from the front part 4c1 of the inner box top surface (the front end of the mounting recess 4c3) to the bottom end of the front protruding surface 91.

The light source 83 is stored in a space partitioned by the lighting storage section 81 and the lighting cover 82, and is arranged so that the light emission direction is tilted backward from the vertical downward direction so that light is emitted at an angle close to perpendicular to the emission surface 90, for example, so that the angle between the light emission direction of the light source 83 and the normal direction of the emission surface 90 is 10° or less.

As shown in FIG. 5, in this embodiment, the inclination angle θ4 of the light emission direction of the light source 83 with respect to the vertical downward direction is greater than the inclination angle θ3 of the emission surface 90 with respect to the horizontal direction, but the inclination angle θ4 may be the same as the inclination angle θ3 of the emission surface 90 with respect to the horizontal direction, or may be smaller than the inclination angle θ3. Also, in this embodiment, the light source 83 is disposed on the insulating space 5 side (above) of the bottom surface of the mounting recess 4c3 on the inner box top surface 4c, but the light source 83 may be disposed below the bottom surface of the mounting recess 4c3.

(4) Effects In the present embodiment described above, the light exit surface 90 of the lighting cover 82 disposed opposite the light source 83 is inclined upward toward the rear at an angle θ3 larger than the angle θ2 of the inner box upper surface rear portion 4c2 with respect to the horizontal direction. Therefore, when a user looks at the inside of the refrigerator compartment 6 from the front, the light exit surface 90 is less noticeable, the user is less likely to feel dazzled, and the aesthetic sense of the interior of the refrigerator compartment is not impaired.

In this embodiment, if the light emission direction of the light source 83 is tilted backward rather than vertically downward, the light emitted from the light source 83 is less likely to be irradiated to the front of the refrigerator compartment 6, and the user is less likely to feel dazzled. In addition, if an uneven surface is provided on the upper surface (the lighting storage section 81 side) of the emission surface 90, the light from the light source 83 can be irradiated at an angle close to perpendicular to the emission surface 90, so the light is more likely to be scattered by the uneven surface, and the inside of the refrigerator compartment 6 can be uniformly illuminated.

In this embodiment, if the forward protruding surface 91 provided in front of the emission surface 90 protrudes downward from the front part 4c1 of the upper surface of the inner box, when a user looks at the inside of the refrigerator compartment 6 from the front, essentially only the forward protruding surface 91 is visible as the lighting device 80, improving the aesthetic appearance of the inside of the refrigerator compartment 6.

In particular, when a shielding portion 88 that covers the rear side of the forward protruding surface 91 is provided between the forward protruding surface 91 and the light source 83, the light from the light source 83 does not pass through the forward protruding surface 91 to reveal the interior of the lighting storage section 81, which does not impair the aesthetic appearance. In this case, when the shielding portion 88 is provided integrally with the lighting storage section 81, the lighting cover 82 is attached to the lighting storage section 81, and the shielding portion 88 is provided on the rear side of the forward protruding surface 91, which provides excellent assembly workability.

In addition, if a colored layer 91a is provided on the forward protruding surface 91, the light from the light source 83 is less likely to pass through the forward protruding surface 91, and the forward protruding surface 91 can be decorated to improve the aesthetic appearance of the interior of the refrigerator compartment 6.

In this embodiment, when the lighting storage section 81 is provided on the inner box top surface 4c by fitting into the insulating space 5 side of the mounting recess 4c3 provided on the inner box top surface 4c, the lighting storage section 81 is positioned by the mounting recess 4c3 when assembling the refrigerator body 2, and the lighting storage section 81 can be easily positioned at a predetermined position and displacement of the lighting storage section 81 due to the foam insulation material filled in the insulating space 5 can be suppressed. Moreover, in this case, the storage opening 84 of the lighting storage section 81 communicates with the mounting opening 4c4 of the mounting recess 4c3, and the locking claw 93 is inserted from below through the mounting opening 4c4 and locks with the locking section 94 of the lighting storage section 81. In other words, the locking claw 93 is inserted into the inner box 4 at the bottom of the mounting recess 4c3 that is recessed upward from the inner box top surface 4c, making it difficult to see the insertion point of the locking claw 93 from the front, and even if light from the light source 83 leaks out from the insertion point of the locking claw 93, it can be blocked by the mounting recess 4c3, improving the aesthetic appearance of the inside of the refrigerator compartment 6.
