Such an air conditioner is a so-called multi-type air conditioner having a plurality of indoor units for one outdoor unit when the air conditioner of the house is a separate type in which the outdoor unit and the indoor unit are separated. , Each indoor unit was provided for each room and was dedicated to that room.

In this way, if one indoor unit is dedicated to one room,
Since a large number of indoor units are required, the cost of the air conditioner becomes high, and as a result, the cost of the house that has the air conditioner as an ancillary facility also becomes high, and since the indoor units are placed in each room It was also disadvantageous in terms of space because it was necessary to secure a space for it.

(2) Therefore, for example, if there is a two-room air conditioner that can adjust the air in two rooms with one indoor unit, the air in the two rooms can be adjusted at the same time, and the air can be effectively placed in the space in the house. It is supposed to be convenient.

The two-room air conditioner proposed here is, for example, an indoor unit of the air conditioner is arranged above the storage space provided between two rooms in a house, and air before adjustment of temperature and the like is supplied from the two rooms. It is formed by connecting the indoor unit and each room by using a suction duct for sucking and taking in the indoor unit, and a blowing duct for the indoor unit to blow out the air whose temperature has been adjusted to the two rooms. It is like

"Problems to be solved by the invention" (1) However, in the two-room air conditioner capable of adjusting the air in the two rooms with one indoor unit as described above, the two rooms, the suction duct or the blowout duct, communicate with each other. , The sound insulation between the two rooms was poor.

(2) The present invention makes it possible to effectively use the space in a house and the energy by adjusting the air in two rooms with one indoor unit, and it is either in use or not in use. Regardless of whether it is a two-room air conditioner that enhances the sound insulation of the two rooms, further, the air in that room is sucked from only the room that needs air adjustment, and only the room that needs air adjustment It is a problem to be solved to provide a two-room air conditioner that blows out adjusted air.

"Means for Solving the Problem" In order to solve the problem, the inventor of the present invention, in view of the above-mentioned drawbacks of the related art, has an indoor space of an air conditioner at the upper part of a storage space provided between two rooms in a house The indoor unit is arranged to communicate with each room by two suction ducts for sucking the air before adjusting the temperature etc. from each of the two rooms and taking it into the indoor unit, and the indoor unit adjusts the temperature etc. To connect the indoor unit and each room by two blowout ducts for blowing the rear air into the two rooms, and to close the room between the indoor unit and each room in the suction duct and the blowout duct. The present invention is characterized in that a damper capable of

[Operation] The operation of the two-room air conditioner according to the present invention will be described below.

(1) First, a case where it is desired to simultaneously air-condition two rooms will be described.

After confirming that the suction duct and the outlet duct communicating between each room and the indoor unit are not blocked by the damper, the indoor unit is operated.

Air is sucked into the indoor unit from each room through the suction duct.

The temperature of the air sucked into the indoor unit is adjusted inside the indoor unit.

The adjusted air is returned to each room through the blowing duct.

(2) Next, a case where it is desired to perform air conditioning in only one of the two rooms will be described.

The damper of the room that does not need to be air-conditioned is operated to close the suction duct and the blow-out duct that connect the room and the indoor unit.

After confirming that the suction duct and the outlet duct that connect the room to be air-conditioned and the indoor unit are not blocked by the damper, operate the indoor unit.

Air is sucked into the indoor unit from the room you want to air-condition through the blowing duct.

The temperature of the air sucked into the indoor unit is adjusted inside the indoor unit.
