  However, in the structure as in Patent Document 1, it is necessary to remove the inner bottom plate during maintenance such as repair or replacement of the lighting device. At this time, if the inside of the cabinet is wide, the size of the inner bottom plate increases accordingly, and the weight of the inner bottom plate increases. For this reason, there arises a problem that it is difficult to perform the work of removing the inner bottom plate by one person.

  The present invention has been made based on recognition of such a problem, and an object of the present invention is to provide a wall cabinet that can easily perform maintenance of a lighting device provided at the bottom.

  A first invention is a cabinet body having an inner bottom plate at the bottom, an outer bottom plate provided below the inner bottom plate, and an illumination device that is positioned between the inner bottom plate and the outer bottom plate and emits light downward. And a suspension mechanism that suspends the outer bottom plate from the cabinet body, and the suspension mechanism separates the outer bottom plate from the inner bottom plate in a state where the outer bottom plate is suspended from the cabinet body. It is a wall cabinet that can.

  According to this wall cabinet, the outer bottom plate can be separated from the cabinet body while maintaining the ceiling suspended state (the state in which the outer bottom plate is suspended from the inner bottom plate) by the suspension mechanism. Therefore, it is not necessary to remove the outer bottom plate that hides a part of the lighting device during maintenance such as repair or replacement of the lighting device. Therefore, even when the outer bottom plate is heavy, the lighting device can be opened to the outside without removing the outer bottom plate, and maintenance such as repair and replacement of the lighting device is facilitated. Further, since the outer bottom plate outside the cabinet body is moved toward the outside (downward) of the cabinet body, the storage space inside the cabinet body is not compressed. That is, the work can be performed without removing the stored items inside the cabinet body during the maintenance. Therefore, it is possible to provide a wall cabinet that can easily perform maintenance of the lighting device provided at the bottom.

  In a second aspect based on the first aspect, the suspension mechanism is a wall cabinet capable of supporting the outer bottom plate at a position separated from the inner bottom plate.

  According to this wall cabinet, in order to prevent the outer bottom plate from being unintentionally separated from or approaching the inner bottom plate during maintenance, for example, the maintenance person needs to support the outer bottom plate at a position separated from the inner bottom plate with one hand. Therefore, the maintenance person can work with both hands, and the maintenance becomes easier.

  According to a third invention, in the second invention, the suspension mechanism is a wall cabinet capable of selecting a position for supporting the outer bottom plate from a plurality of locations.

  According to this wall cabinet, it is possible to support the outer bottom plate at an appropriate position (height) for the maintenance person, and maintenance is easier. Further, it is easy to return the outer bottom plate to the position during normal use without separating the outer bottom plate from the inner bottom plate more than necessary.

  According to a fourth invention, in any one of the first to third inventions, the outer bottom plate is a wall cabinet having a lighting device receiving portion on which the lighting device can be installed.

  According to this wall cabinet, the lighting device can be attached to the wall cabinet simply by attaching the outer bottom plate on which the lighting device is installed to the bottom plate (inner bottom plate) of the cabinet body. That is, the lighting device can be easily retrofitted to a wall cabinet where no lighting device is installed.
