  As a result, in the air conditioner that does not cover the operation mode display section when the oxygen enrichment stop delay operation is being performed, the state during the oxygen enrichment stop delay operation can be visually distinguished clearly. It becomes.

  The air conditioner of the present invention can visually distinguish the state even when the oxygen enrichment stop delay operation is performed when the main body is stopped.

  The first invention comprises a vacuum pump unit and an oxygen-enriched membrane unit, and air having a high oxygen concentration that has permeated through the oxygen-enriched membrane unit by the suction force of the vacuum pump unit can be sent indoors through a tube. The interior of an air conditioner that forms a wind circuit from a housing having one or more inlets such as the front surface and one or more outlets such as the lower surface, a heat exchanger housed in the housing, and a cross-flow fan The center of the unit is provided with a light display unit that indicates the operating state of the vacuum pump unit, and the indoor unit front part is provided with a movable front panel that opens when the main body is operated and closes when the main body is stopped. In an air conditioner that covers the light display when the panel is closed, when the vacuum pump unit is operating without stopping immediately when a main unit operation stop instruction is issued. In the meantime, the operation of closing the front panel is not performed, and the operation of closing the front panel is performed after the operation of the vacuum pump unit is stopped. It is possible to prevent the front panel from being opened and covering the light display portion.

  In the second aspect of the invention, in particular, when the air conditioner of the first aspect of the invention operates without stopping immediately when the vacuum pump unit issues a main body operation stop instruction, By displaying that the stop delay operation is being performed, the oxygen enrichment delay operation is displayed without obscuring the light display portion, and it is possible to visually distinguish clearly.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

  First, the indoor unit is in the state shown in FIG. 1 during operation.

  If an instruction to stop the operation of the main body is issued (step 1), it is determined whether or not the main body is in an oxygen enrichment operation (step 2).

  When it is determined that the oxygen enrichment operation is being performed, the main body determines whether it is necessary to perform the oxygen enrichment stop delay operation (step 3).

  When it is determined that the oxygen enrichment stop delay operation is necessary, the main body keeps the front panel open (the state shown in FIG. 1), performs the oxygen enrichment stop delay operation, and displays by operation mode. The fact that the oxygen enrichment stop delay operation is being performed is displayed on the part 2 (step 4).

  It is determined whether or not the main body ends the oxygen enrichment stop delay operation (step 5), and if it is determined to end, the main body stops the oxygen enrichment stop delay operation, and the oxygen enrichment on the display section for each operation mode The display indicating that the stop delay operation is being performed is stopped, the front panel is closed (step 6), and the state shown in FIG. 2 is obtained.

  When the operation stop instruction of the main body is issued, if the oxygen enrichment operation is not performed or if the oxygen enrichment stop delay operation is not necessary, the state immediately proceeds to the state of FIG. 2 (step 6).

  As described above, in the present embodiment, a vacuum pump unit and an oxygen-enriched membrane unit are provided, and air with a high oxygen concentration that has passed through the oxygen-enriched membrane unit by the suction force of the vacuum pump unit is passed through the tube. A wind circuit is composed of a housing that can be sent indoors and that has one or more inlets, such as the front, and one or more outlets, such as the lower surface, and a heat exchanger and a once-through fan stored in the housing.
