Abstract

An air conditioner includes: an air-conditioning control unit; a data read and write unit; a data control unit; and an operation unit. The air-conditioning control unit controls air-conditioning running based on running information; the data read and write unit to which a storage medium configured to store therein data can be removably connected; the data control unit transfers the running information and the operation setting information transmitted from the air-conditioning control unit to the data read and write unit; and the operation unit can input the operation setting information for performing an operation of the air-conditioning running.

Claims

1. An air conditioner comprising:

an air-conditioning control unit that controls air-conditioning running based on running information that is action information during running and operation setting information;

a data read and write unit to which a storage medium configured to store therein data can be removably connected, and that can write running information and operation setting information transmitted from the air-conditioning control unit in the storage medium during air-conditioning running and can read running information and operation setting information stored in the storage medium before stop of running, from the storage medium when restarting air-conditioning running;

a data control unit that transfers the running information and the operation setting information transmitted from the air-conditioning control unit to the data read and write unit to be written in the storage medium, or transfers, to the air-conditioning control unit, the running information and the operation setting information stored in the storage medium before stop of running and read from the storage medium by the data read and write unit; and

an operation unit that can input the operation setting information for performing an operation of the air-conditioning running.

2. The air conditioner according to claim 1, further comprising a communication unit that performs transmission and reception of data between the data control unit and the data read and write unit in a bidirectional manner, wherein

the air-conditioning control unit automatically transmits the running information and the operation setting information to the data control unit on a regular basis,

the data control unit stores the running information and the operation setting information received from the air-conditioning control unit in a storage file together with storage-date information, and then transmits the storage file to the data read and write unit via the communication unit, and

the data read and write unit receives the storage file from the data control unit and writes the received file in the storage medium.

3. The air conditioner according to claim 2, wherein the operation unit transmits, to the air-conditioning control unit, information for setting an interval at which the air-conditioning control unit automatically transmits the running information and the operation setting information to the data control unit.

4. The air conditioner according to claim 2, wherein

the air-conditioning control unit causes the data read and write unit to read the running information and the operation setting information stored in the storage medium before stop of running, from the storage medium when restarting the air conditioner after the stop of the running,

the data control unit transmits, to the air-conditioning control unit, the running information and the operation setting information stored in the storage medium before stop of running and received from the data read and write unit via the communication unit, and

the air-conditioning control unit restarts air-conditioning running based on the running information and the operation setting information stored in the storage medium before the stop of the running.

5. The air conditioner according to claim 4, wherein the operation unit transmits, to the air-conditioning control unit, an instruction for the air-conditioning control unit to cause the data read and write unit to read the running information and the operation setting information stored in the storage medium before stop of running, from the storage medium.

6. The air conditioner according to claim 4, wherein the air-conditioning control unit causes the data read and write unit to read the running information and the operation setting information stored in the storage medium before stop of running, from the storage medium when restarting the air conditioner after an occurrence of an abnormality is detected during air-conditioning running and the running is stopped.

7. The air conditioner according to claim 1, wherein the air-conditioning control unit, the data control unit, the communication unit, and the data read and write unit are provided on a control board.

8. The air conditioner according to claim 1, wherein

the air-conditioning control unit is provided on a control board, and

the data control unit, the communication unit, and the data read and write unit are provided on the operation unit.
