Abstract

PURPOSE:To restart an operation of an air conditioner under previous optimum conditions by storing a setting mode, conditions during operation in a nonvolatile memory provided in a controller for the conditioner, reading the memory at the time of restarting, and setting the mode and the conditions according to the read mode and conditions. CONSTITUTION:A signal from a remote controller 2 is input together with a set condition signal from an operation switch 3 to a set input circuit 4, and the circuit 4, a body side ON switch 5, and a sensor 6 which inputs signals from sensors are connected to a controller 1. A memory 7 which stores an initial setting condition set the setting condition from the circuit 4 as 'an automatic operation', is provided in the controller 1. One is selected by a control condition selector 8, and the operation of a compressor 10 is controlled by a compressor controller 9. An external memory 11 which stores a setting mode and a set temperature at the time of previous operation, is connected to the selector 8. Accordingly, the operation can be started under the previous optimum conditions at the time of restarting.

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for an air conditioner.

0002

[Prior Art] Conventionally, when an air conditioner is plugged in and started up using a switch on the main unit, it starts up in a preset automatic operation (auto operation), and depending on the room temperature, humidity, outside temperature, etc. The system automatically sets operating modes such as heating, cooling, and defrosting, as well as air volume, direction, and temperature settings, and starts operation. In this way, data such as set temperature, air volume, and wind direction suitable for the room in which it is installed, which was required based on previous experience, could not be imported immediately after startup, and after startup, it was not possible to obtain data from the wireless remote control or the main unit's operation panel. Changes are now made manually, which not only cannot guarantee that the correct data is included;
Inaccurate data or missing data occurred, and driving conditions were not always comfortable.

0003

[Problems to be Solved by the Invention] The present invention has been made in view of the above-mentioned conventional problems, and is an air conditioner that performs controlled operation based on data obtained from previous experience at the same time as the start of operation. The purpose is to provide a control device for

0004

[Means for solving the problem] In order to achieve the above object, a rewritable non-volatile memory is provided in the control section of the air conditioner to memorize the setting mode and conditions during operation, and when restarting after stopping, The setting mode and conditions are read from non-volatile memory, and the setting mode and conditions are set based on the contents.

[0005]

[Operation] According to the above configuration, the control unit of the air conditioner is provided with a writable non-volatile memory that stores data such as the setting mode and setting temperature at the time of the previous operation, and the setting mode and the setting temperature at the time of the last operation stop. The system stores data such as the following data, reads the data from the memory at the start of operation, and starts operation according to the contents.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a block diagram showing the configuration of the present invention, in which setting conditions are sent to a control unit 1 by an infrared signal from a remote control device 2, or an operation switch 3 provided on a main unit operation unit is used.
A setting input circuit 4 for inputting setting conditions from the main body, an ON switch 5 on the main body side of the main body, and a sensor section 6 for inputting signals from each sensor are connected, and the control section 1 is provided with a memory 7. The setting conditions from the setting input circuit 4 and the initial setting conditions preset as "automatic operation" are stored in the control condition selection circuit 8, and the control condition selection circuit 8 selects one of the setting conditions to operate the compressor. Compressor 1 by control circuit 9
Controls the operation of 0. Furthermore, the control condition selection circuit 8
A writable nonvolatile external memory 11 (for example, EEPROM, etc.) is provided which is connected to and added to the outside. When the setting conditions are selected and the operation of the compressor 10 is started, the control condition selection circuit 8 writes the control conditions into the external memory 11, and the external memory 11 retains the memory even after the operation of the air conditioner is stopped. In this state, when the air conditioner is restarted by the ON switch 5 on the main body side (the same applies when the power plug is inserted), the control condition selection circuit 8 reads out the setting conditions from the previous operation stored from the external memory 11, As an initial setting condition, the operation of the compressor 10 is controlled by the compressor control circuit 9. In this way, unless the setting conditions are changed from the remote control device 2 or the operation switch 3, operation can be started according to the setting conditions from the previous operation, and the installation conditions that were required based on experience up to the previous operation can be started. Data such as set temperature, air volume, and wind direction suitable for the room can be incorporated from the start of startup without having to make new settings.

FIG. 2 is a flowchart showing the details of the present invention. First, the air conditioner is powered on, and data such as set temperature, air volume, and wind direction suitable for the room in which it is installed and the setting conditions for "automatic operation" are entered. Remote control device 2 or operation switch 3
to initialize the setting conditions (21). Next, it is determined whether the power ON is not from the remote control device or the operation switch but from the ON switch 5 on the main body side of the main body (22), and if it is from the power ON switch 5 on the main body, the setting conditions are stored in the external memory 11. (23)
), if the setting conditions are stored, external memory 1
The setting conditions are read from 1 (24), and the operation of the compressor 10 is started according to the read setting conditions (25). If it is not stored in the external memory 11, "automatic operation" is performed according to the setting conditions set in advance and stored in the memory 7 (33). Thereafter, if there is no change in the settings from the remote control device 2 or the like (26), operation continues under the same settings. When a change in the settings is input from the remote control device 2, etc., the settings are changed and the operation is started (27), and at the same time, the changed settings are written in the external memory 11 (28).
), continue operation with the same setting conditions. If the power supply 0N is not determined by the 0N switch 5 on the main body side, select the setting condition of "Automatic operation" (22) (29), and if there is a setting input from the remote control device 2 etc. (30), the setting condition will be changed. (31), the set conditions are written into the external memory 11 by the control condition selection circuit 8 (32), and the operation is continued.

[0008]

Effects of the Invention As described above, in the present invention, setting data such as the setting mode and setting temperature from the previous operation is stored in an external memory, and at the start of operation, the setting data is read from the external memory and used as the setting condition for operation. By starting , it is possible to start operation under the previous optimum conditions.
