  The control unit 60 comprising a microcomputer provided on the control board 26 includes an R sensor 29, an R fan 30, an F sensor 35, an F fan 34, a compressor 24, an ice making device 66, a door switch 62, and a door pressing unit 64. The open / close detection unit 67 and the operation unit 56 are connected. Further, the control unit 60 is provided with an upper illumination unit 84, a lower left illumination unit 90, and a lower right illumination unit 96. The open / close detection unit 67 is a switch that detects an open state of at least one of the left and right doors 141 and 142, and is provided on the front surface of the cabinet 12.

  The control unit 60 uses the upper illumination unit 84, the lower left illumination unit 90, and the lower right illumination unit 96 to change the luminance and illumination color (color temperature) of the LEDs 88, 94, and 100.

(4) Illumination method in chilled chamber 42 Next, an illumination method in the chilled chamber 42 will be described.

  First, when the user opens the left and right doors 141 and 142, the control unit 60 detects the open state by the open / close detection unit 67, and the plurality of LEDs 88 of the upper illumination unit 84, the LEDs 94 of the lower left illumination unit 90, and the lower right illumination unit. The 96 LEDs 100 are turned on.

  The user pulls out the upper container 70, the lower left container 72, and the lower right container 74, puts food, and stores the upper container 70, the lower left container 72, and the lower right container 74 in the chilled chamber 42 again. Here, what kind of food is stored in which of the upper container 70, the lower left container 72, and the lower right container 74 is set in advance. This is because the illumination color and brightness of the LED 88, LED 94, and LED 100 are appropriately set corresponding to the set food type. For example, it is assumed that the upper container 70 is set to meat, the lower left container 72 is set to fish, and the lower right container 74 is set to vegetables.

  In this state, the plurality of LEDs 88 of the upper illumination unit 84, the LED 94 of the lower left illumination unit 90, and the LED 100 of the lower right illumination unit 96 are the meat food in the upper container 70, the fish food in the lower left container 72, the lower right Each of the vegetable foods in the container 74 is illuminated.

  Thereby, the user visually recognizes the food stored in each container 70, 72, 74. Since the illumination color and brightness of the LED 88, LED 94, and LED 100 are changed corresponding to each of the containers 70, 72, and 74, each food can be illuminated with good appearance. “Looking nicely” means an appearance that reminds us that the food is fresh and delicious. For example, regarding the meats in the upper container 70, the light wavelength distribution of the LED 88 can be shown with good freshness by forming a valley bottom at 550 nm to 600 nm to reduce yellow light and increase red. Further, regarding the fish in the lower left container 72, the LED 94 can be displayed with good freshness by reducing yellow light and increasing blue. Further, regarding the vegetables in the lower right container 74, the LED 100 can be displayed with good freshness by reducing yellow light and increasing green.

  Finally, when the user closes the left and right doors 141 and 142, the control unit 60 detects the closed state by the open / close detection unit 67, and the plurality of LEDs 88 of the upper illumination unit 84, the LEDs 94 of the lower left illumination unit 90, and the lower right illumination unit. The 96 LEDs 100 are turned off.

(5) Effect According to this embodiment, the upper illumination part 84 is provided behind the upper container 70, the lower left illumination part 90 is provided behind the lower left container 72, and the lower right container 74 is provided behind the lower right illumination part 96. By providing and illuminating the food stored in each container 70, 72, 74 from the rear, there is no shadowed portion as in the conventional case, and the visibility of the food is good.

  Further, the LED 88 is disposed at a position higher than the central portion in the height direction of the upper container 70, the LED 94 is disposed at a position higher than the central portion in the height direction of the lower left container 72, and the LED 100 is disposed in the lower right container 74. It is arranged at a position higher than the central part in the height direction. Therefore, since the food stored in each container 70, 72, 74 is illuminated from the rear upper side, the food is brightly illuminated and the visibility is improved.

  Further, the upper illumination unit 84 is arranged so as to straddle the lower left container 72 and the lower right container 74, and the position in the width direction of the lower left illumination unit 90 and the lower right illumination unit 96 is the same as the position in the width direction of the upper illumination unit 84. Since it is provided at a position that is off, the entire inside of the chilled chamber 42 can be illuminated uniformly.

  In addition, since the lamp cover 102 is provided so as to cover the entire upper illumination unit 84, lower left illumination unit 90, and lower right illumination unit 96, the user does not directly view the light from the LEDs 88, 94, and 100, and chilled. The entire interior of the chamber 42 can be illuminated.

  In addition, in the state where the upper container 70, the lower left container 72, and the lower right container 74 are accommodated in the chilled chamber 42, the illumination range of the LED 88 is an area in which the lower left container 72 and the lower right container 74 can be illuminated. Is the range in which the upper container 70 can be illuminated. Therefore, it will be in the state which mutually illuminates each container 70,72,74, and can illuminate the inside more brightly.

  Further, the LED 88 is positioned behind the handle 76 of the upper container 70, the LED 94 is positioned behind the handle 78 of the lower left container 72, and the LED 100 is positioned behind the handle 80 of the lower right container 74. Therefore, each handle 76, 78, 80 is illuminated brighter than the other parts, and its position is easily understood. Further, the presence of the handles 76, 78, and 80 can prevent the user from directly viewing the illuminated state of the LEDs 88, 94, and 100.

  Further, by changing the illumination color (color temperature) and brightness of the LED 88 of the upper illumination unit 84, the LED 94 of the lower left illumination unit 90, and the LED 100 of the lower right illumination unit 96, respectively, according to food, each container 70, 72 is changed. , 74 can illuminate the food stored nicely.

  Since the control unit 62 turns on the upper illumination unit 84, the lower left illumination unit 90, and the lower right illumination unit 96 only when the left and right doors 141 and 142 are in the open state and turns off the light when the door is closed, it can contribute to energy saving. .

(6) Modification Example In the above embodiment, the brightness and illumination color of the LED 88 of the upper illumination unit 84, the LED 94 of the lower left illumination unit 90, and the LED 100 of the lower right illumination unit 96 are set in advance. First, the brightness and the illumination color may be changed by operating the operation switch 58 of the operation unit 56.

  Further, the illumination light of the LED of the low temperature container may be illuminated so as to increase the color temperature by increasing the light in the red light wavelength band than the illumination light of the LED of the high temperature container.
