  However, in the above-described conventional configuration, in a drawer-type storage room that has been adopted in mainstream refrigerators in recent years, even if an interior light is placed on the top surface of the storage room, the target food is illuminated by being pulled out. Had the problem of not being.

  This invention solves the said conventional subject, and it aims at providing the refrigerator which enabled the suitable illumination to the foodstuff of a drawer-type storage room.

  In order to solve the above-described conventional problems, a refrigerator according to the present invention includes a drawer-type storage room, an interior lamp that illuminates the drawer-type storage room, door opening / closing detection means that detects opening and closing of the storage room, The interior lamp energization control means for controlling the lighting is provided, and the interior lamp is arranged at the lower part of the upper drawer type storage room arranged at the upper part of the drawer type storage room.

  As a result, when the drawer-type storage room is pulled out, it is possible to illuminate the target food that is directly below the user's line of sight, thereby improving visibility.

  The refrigerator of the present invention improves the visibility of food in the storage room, improves usability, and allows food to be confirmed in a short time by improving the visibility. A contributed refrigerator can be provided.

The invention according to claim 1 detects a pull-out storage room cooled by cold air generated by a cooler of a refrigeration cycle, an interior light that illuminates the pull-out storage room, and opening / closing of the pull-out storage room A door open / close detection means for controlling and an interior light energization control means for controlling lighting of the interior light, and the interior light is disposed at the lower part of the upper drawer-type storage chamber disposed above the pull-out storage room As a result, a refrigerator with good functionality can be provided without being visible from the outside and without affecting the appearance design.

  The invention according to claim 2 is the invention according to claim 1, wherein the interior lamp is positioned in front of the lower part of the upper pull-out storage room, and the food container is used while the storage container of the pull-out storage room is pulled out. When the interior lamp is positioned directly above the food when it comes out to a position that can be seen by a person, it is possible to illuminate the food from the front of the drawer and provide a refrigerator with good food visibility.

  The invention according to claim 3 is the invention according to claim 1 or 2, wherein the interior lamp is constituted by an LED, so that it has a small and space-saving configuration and is not limited to the mounting location. Can do.

  According to a fourth aspect of the present invention, there is provided the refrigerator according to any one of the first to third aspects, wherein the pull-out storage chamber is at least a freezing chamber, thereby accurately lighting the food. it can.

(Embodiment 1)
FIG. 1 is a block diagram of the refrigerator control device according to Embodiment 1 of the present invention, and shows the configuration and operation of the refrigerator.

  In FIG. 1, a refrigerator 2 includes a freezer compartment 1, a drawer-type storage container 6, a freezer compartment door 3 that opens and closes the freezer compartment 1, door open / close detection means 7 that detects opening and closing of the freezer compartment door 3, and a freezer compartment. The storage room door 5 located above the door 3, the LED interior light 4 installed at the lower part of the storage room door 5, and the input of the detection signal from the door open / close detection means 7 turn on the LED interior light 4. The interior lamp energization control means 8 controls the interior lamp energization control means 8. The interior lamp energization control means 8 receives the power transmitted wirelessly and the wireless power transmission means 9 that wirelessly transmits the power necessary for LED lighting and energizes the LEDs. And a wireless power receiving means 10 for converting the current into a current.

  About the refrigerator 2 comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, after the refrigerator 2 is powered on, the freezer compartment 1 stores food as the internal temperature decreases due to the start of cooling. When the user of the refrigerator 2 takes out the food, the freezer compartment door 3 is opened and the storage container 6 of the freezer compartment 1 is pulled out. At this time, the door open / close detection means 7 detects the opening of the freezer compartment door 3 and inputs a detection signal “open” to the interior lamp energization control means 8. The interior lamp energization control means 8 outputs the energization to the LED interior lamp 4 by the input of the detection signal “open”, and the LED interior lamp 4 is turned on.

  At this time, since the LED interior light 4 is installed in the lower part of the storage room door 5 located in the upper part of the freezer compartment door 3, the storage container 6 is pulled out and the food is visible to the user. The LED interior light 4 is located immediately above the food when it comes, so that the food can be accurately illuminated. Moreover, since it is arrange | positioned outside a storage room, there is no adhesion of frost and the interior lamp which does not become dark is provided.

  The LED interior light 4 is disposed below the storage room door 5 (for example, the ice storage door 5) together with the wireless power receiving means 10 of the interior light energization control means 8, and the LED power is supplied from the wireless power transmission means 9 wirelessly. Since it can be controlled, the ice storage room door 5 can be disposed at any position without being restricted by the opening / closing mechanism of the ice storage room door 5.

As described above, in this embodiment, a bright interior light that can appropriately illuminate the food of the storage container with respect to the user's line of sight according to the opening and closing of the door of the freezer, and has no frost adhesion I will provide a.

  In the present embodiment, the control for turning on / off the interior lamp of the freezer has been described. However, the present invention is not limited to the freezer compartment, but can be applied to all storage rooms having a drawer-type door.

  As described above, the refrigerator according to the present invention is capable of illuminating an appropriate position of the food from the user's line of sight in the pull-out type storage room by providing the interior lamp in the upper part outside the storage room. Therefore, it can be applied to a refrigerator for home use or business use, and can also be applied to a wide range of equipment to which LED lighting is applied, such as an article storage device having a drawer type door.
