Definitions
- the present invention relates to air conditioners, and in particular, to an air conditioner having a ventilating part that ventilates a room.
- an air conditioner in which an indoor unit and an outdoor unit are connected with each other via a ventilation pipe, and one end of the ventilation pipe is connected to the inlet side and the outlet side of an air blower provided for the outdoor unit switchably by means of a damper ( JP 2003-176944 A ).
- the ventilation pipe is connected to the inlet side of the air blower, and the air blower takes in indoor air via the ventilation pipe and the indoor unit and discharges the air to the outside of the room in a first switch position of the damper.
- the ventilation pipe is connected to the outlet side of the air blower, and the air blower supplies the outdoor air to the inside of the room via the ventilation pipe and the indoor unit.
- the air conditioner also includes a remote controller that receives a command of an operating state from an operator and transmits a signal corresponding to the command to the indoor unit, and a control part that controls the operating state of the air conditioner in accordance with the signal from the remote controller.
- a remote controller that receives a command of an operating state from an operator and transmits a signal corresponding to the command to the indoor unit
- a control part that controls the operating state of the air conditioner in accordance with the signal from the remote controller.
- the conventional air conditioner enters a stop state even if the power failure is recovered and sometimes fails in returning to the ventilating operation before the power failure.
- the remote controller is set back to its initial state, and a signal of the initial state is transmitted to the indoor unit, sometimes stopping the air conditioner.
- EP 0837 289 A2 is concerned with an air conditioner and JP 2001 099477A is concerned with a ventilating fan.
- the operation of the ventilating part is controlled to the operating state by the control part at the present time of operation on the basis of the operation information that is the operation information stored in the first nonvolatile memory and represents the operating state.
- the ventilating part by controlling the ventilating part so that the operating state becomes identical to the operating state at the previous time of operation even when the ventilating operation stops due to, for example, power failure, the ventilating operation can be resumed at the present time of operation after recovery from the power failure. Therefore, the disadvantage that the ventilating operation stops though no command for stopping the ventilating operation has been received as in the conventional case can be prevented.
- the air conditioner further comprises:
- the command signal is transmitted from the transmitting part of the remote controller on the basis of the input to the remote controller by the operator.
- the command signal is received by the receiving part of the indoor unit, and the ventilating part is controlled to the operating state corresponding to the command signal.
- the operation information signal that represents the operation information stored in the first nonvolatile memory of the indoor unit is transmitted by the transmitting part of the indoor unit.
- the operation information signal is received by the receiving part of the remote controller. Therefore, since the wireless remote controller can obtain the information identical to the operation information stored in the first nonvolatile memory of the indoor unit even when the operating state is set back to the initial state due to, for example, replacement of the battery of the remote controller, the operation information can be prevented from differing between the remote controller and the indoor unit. Therefore, the disadvantage that the command signal of the initial state is transmitted from the remote controller set back to the initial state to the indoor unit and the operation of the ventilating part stops though no command of stopping the ventilating operation is inputted to the remote controller can be prevented.
- the air conditioner further comprises:
- the operation information of the ventilating part at the previous time of operation is stored in the second nonvolatile memory of the outdoor unit. Therefore, the operation information of the ventilating part can be backed up in preparation for the vanishment of the operation information in the first nonvolatile memory due to, for example, the failure or replacement of the indoor unit.
- the remote controller comprises:
- the operation information of the ventilating part at the previous time of operation is stored in the third nonvolatile memory of the remote controller.
- the operation information signal that represents the operation information stored in the third nonvolatile memory is transmitted to the indoor unit by the transmitting part.
- the control part controls the operation of the ventilating part on a basis of the stored operation information so that the operating state becomes identical to the operating state at the previous time of operation.
- the operation information stored in the first nonvolatile memory, the second nonvolatile memory or the third nonvolatile memory is referred to.
- the operation of the ventilating part is controlled so as to enter the operating state identical to the operating state at the previous time of operation on the basis of the stored operation information.
- control part may control the operation of the ventilating part at the present time of operation so as to enter the operating state identical to at least part of the operating state at the previous time of operation.
- the air conditioner of the present invention includes the ventilating part that ventilates the room, the first nonvolatile memory that stores the operation information representing the operating state of the ventilating part at the previous time of operation, and the control part that controls the operation of the ventilating part on the basis of the operation information stored in the first nonvolatile memory at the present time of operation. Therefore, even when the ventilating operation stops due to, for example, power failure, the ventilating operation can be resumed at the present time of operation after recovery from the power failure. Therefore, the disadvantage that the ventilating operation stops after recovery from power failure as in the conventional case can be prevented.

Description
- The present invention relates to air conditioners, and in particular, to an air conditioner having a ventilating part that ventilates a room.
- Conventionally, there is disclosed an air conditioner, in which an indoor unit and an outdoor unit are connected with each other via a ventilation pipe, and one end of the ventilation pipe is connected to the inlet side and the outlet side of an air blower provided for the outdoor unit switchably by means of a damper (
JP 2003-176944 A - In the conventional air conditioner, the ventilation pipe is connected to the inlet side of the air blower, and the air blower takes in indoor air via the ventilation pipe and the indoor unit and discharges the air to the outside of the room in a first switch position of the damper. On the other hand, in a second switch position of the damper, the ventilation pipe is connected to the outlet side of the air blower, and the air blower supplies the outdoor air to the inside of the room via the ventilation pipe and the indoor unit. By thus discharging the indoor air to the outside of the room or supplying the outdoor air to the inside of the room by the air conditioner, indoor air ventilating operation is performed.
- The air conditioner also includes a remote controller that receives a command of an operating state from an operator and transmits a signal corresponding to the command to the indoor unit, and a control part that controls the operating state of the air conditioner in accordance with the signal from the remote controller. When the operator commands the remote controller to perform ventilating operation, the control part that receives the signal from the remote controller controls the damper and the air blower to perform the ventilating operation.
- However, in a case where power failure occurs while the ventilating operation is performed, the conventional air conditioner enters a stop state even if the power failure is recovered and sometimes fails in returning to the ventilating operation before the power failure. Moreover, when the battery of the remote controller is replaced while the ventilating operation is performed, the remote controller is set back to its initial state, and a signal of the initial state is transmitted to the indoor unit, sometimes stopping the air conditioner.
- Recently, all buildings are obliged to be equipped with a mechanical ventilation facility in principle as a countermeasure to the so-called sick house syndrome due to the revision of Building Standard Law.
- However, there is a problem that the conventional air conditioner, which sometimes stops the ventilating operation though it has not received the command of stopping the ventilating operation by the operator as described above, is therefore not able to function as a mechanical ventilation facility provided by Building Standard Law.
- Further,
EP 0837 289 A2 is concerned with an air conditioner andJP 2001 099477A - It is an object of the present invention to provide an air conditioner capable of preventing the disadvantage that the ventilating operation stops though no command of stopping the ventilating operation has been received from the operator.
- In order to achieve the above object, there is provided an air conditioner according to
claim 1. - According to the above construction, when the ventilating part was in the operating state at the previous time of operation, the operation of the ventilating part is controlled to the operating state by the control part at the present time of operation on the basis of the operation information that is the operation information stored in the first nonvolatile memory and represents the operating state. For example, by controlling the ventilating part so that the operating state becomes identical to the operating state at the previous time of operation even when the ventilating operation stops due to, for example, power failure, the ventilating operation can be resumed at the present time of operation after recovery from the power failure. Therefore, the disadvantage that the ventilating operation stops though no command for stopping the ventilating operation has been received as in the conventional case can be prevented.
- According to the invention, the air conditioner further comprises:
- an indoor unit having the first nonvolatile memory, a receiving part that receives a command signal for commanding the operating state of the ventilating part and a transmitting part that transmits an operation information signal representing the operation information stored in the first nonvolatile memory; and
- a wireless remote controller having a transmitting part that transmits the command signal and a receiving part that receives the operation information signal.
- According to the embodiment, the command signal is transmitted from the transmitting part of the remote controller on the basis of the input to the remote controller by the operator. The command signal is received by the receiving part of the indoor unit, and the ventilating part is controlled to the operating state corresponding to the command signal.
- Moreover, the operation information signal that represents the operation information stored in the first nonvolatile memory of the indoor unit is transmitted by the transmitting part of the indoor unit. The operation information signal is received by the receiving part of the remote controller. Therefore, since the wireless remote controller can obtain the information identical to the operation information stored in the first nonvolatile memory of the indoor unit even when the operating state is set back to the initial state due to, for example, replacement of the battery of the remote controller, the operation information can be prevented from differing between the remote controller and the indoor unit. Therefore, the disadvantage that the command signal of the initial state is transmitted from the remote controller set back to the initial state to the indoor unit and the operation of the ventilating part stops though no command of stopping the ventilating operation is inputted to the remote controller can be prevented.
- In one embodiment of the invention, the air conditioner further comprises:
- an outdoor unit having a second nonvolatile memory that stores the operation information of the ventilating part at the previous time of operation.
- According to the above embodiment, the operation information of the ventilating part at the previous time of operation is stored in the second nonvolatile memory of the outdoor unit. Therefore, the operation information of the ventilating part can be backed up in preparation for the vanishment of the operation information in the first nonvolatile memory due to, for example, the failure or replacement of the indoor unit.
- In one embodiment of the invention, the remote controller comprises:
- a third nonvolatile memory that stores the operation information of the ventilating part at the previous time of operation, and
- the transmitting part transmits the operation information signal that represents the operation information stored in the third nonvolatile memory to the indoor unit.
- According to the above embodiment, the operation information of the ventilating part at the previous time of operation is stored in the third nonvolatile memory of the remote controller. The operation information signal that represents the operation information stored in the third nonvolatile memory is transmitted to the indoor unit by the transmitting part. By this operation, the operation information of the ventilating part at the previous time of operation can be backed up in preparation for the vanishment of the operation information in the first or second nonvolatile memory due to, for example, replacement or another cause of electrical components.
- In one embodiment of the invention, when the receiving part of the indoor unit does not receive the command signal for commanding execution of ventilation of the ventilating part at the present time of operation and the operating state of the ventilating part at the previous time of operation represented by the operation information stored in the first nonvolatile memory, the second nonvolatile memory or the third nonvolatile memory is execution of ventilation, the control part controls the operation of the ventilating part on a basis of the stored operation information so that the operating state becomes identical to the operating state at the previous time of operation.
- According to the above embodiment, when the receiving part does not receive the command signal that commands the execution of the ventilation of the ventilating part at the present time of operation, the operation information stored in the first nonvolatile memory, the second nonvolatile memory or the third nonvolatile memory is referred to. When the operating state of the ventilating part at the previous time of operation represented by the operation information stored in the first nonvolatile memory, the second nonvolatile memory or the third nonvolatile memory indicates the execution of ventilation, the operation of the ventilating part is controlled so as to enter the operating state identical to the operating state at the previous time of operation on the basis of the stored operation information. Therefore, when, for example, the previous operation has stopped due to, for example, power failure, the ventilating operation can be resumed as in the previous operation even if the command of executing ventilation is not received from the operator at the time of resuming the present operation. It is noted that the control part may control the operation of the ventilating part at the present time of operation so as to enter the operating state identical to at least part of the operating state at the previous time of operation.
- As described above, the air conditioner of the present invention includes the ventilating part that ventilates the room, the first nonvolatile memory that stores the operation information representing the operating state of the ventilating part at the previous time of operation, and the control part that controls the operation of the ventilating part on the basis of the operation information stored in the first nonvolatile memory at the present time of operation. Therefore, even when the ventilating operation stops due to, for example, power failure, the ventilating operation can be resumed at the present time of operation after recovery from the power failure. Therefore, the disadvantage that the ventilating operation stops after recovery from power failure as in the conventional case can be prevented.

-
FIG. 1 is a schematic view showing an air conditioner according to a first embodiment of the present invention. - The air conditioner includes an
indoor unit 1 placed on a wall surface or the like of a room, and anoutdoor unit 2 placed outside the room, and theindoor unit 1 and theoutdoor unit 2 are connected with each other via arefrigerant piping 5, aventilation pipe 6 and aconnection wiring 8. - The
indoor unit 1 has an indoor heat exchanger (not shown) to which a refrigerant is supplied from theoutdoor unit 2 via therefrigerant piping 5 and a crossflow fan that guides wind to the indoor heat exchanger. Moreover, an opening that communicates with theventilation pipe 6 is provided on a wind passage generated by the crossflow fan, forming a structure in which outdoor air is supplied to the inside of a room and the indoor air is discharged to the outside of the room via the opening. - Moreover, the
indoor unit 1 has an infrared ray transmitting and receiving part 13 that transmits and receives an infrared signal between the part and awireless remote controller 3 as a remote controller described later. In detail, the infrared ray transmitting and receiving part 13 receives command signals for commanding the operating states of an operating mode, a preset temperature, a preset air volume, a wind direction and so on from thewireless remote controller 3 and transmits an operation information signal that represents the operating state of the air conditioner to thewireless remote controller 3. As described above, the infrared ray transmitting and receiving part 13 functions as a receiving part and a transmitting part. - The wireless
remote controller 3 has an input part to which the operating states of the preset temperature, preset air volume, wind direction and so on are commanded and inputted by an operator in the room. The wirelessremote controller 3 also has an infrared ray transmitting and receivingpart 31 that transmits and receives an infrared signal between the part and theindoor unit 1 to transmit a command signal corresponding to the input to the input part to theindoor unit 1 and receive an operation information signal concerning the operation information from theindoor unit 1. As described above, the infrared ray transmitting and receivingpart 31 functions as a receiving part and a transmitting part. - The
indoor unit 1 further includes a first EEPROM (Electrically Erasable Programmable Read-Only Memory) 11 as a first nonvolatile memory that stores the operation information representing the operating state of the air conditioner at the present time of operation. - The
indoor unit 1 further includes an information communicating part that carries out information communication between the unit and theoutdoor unit 2 to transmit the command signal received from the wirelessremote controller 3 to theoutdoor unit 2. The information communicating part transmits an operation information signal that represents the operation information (information identical to the information to be stored in the first EEPROM 11) at the present time of operation to theoutdoor unit 2 and receives the operation information signal concerning the air conditioner at the previous time of operation from theoutdoor unit 2. - The
outdoor unit 2 includes anoutdoor unit 21 and ahumidifying unit 22. A compressor that compresses a refrigerant, an expander that reduces the pressure by adiabatically expanding the refrigerant, an outdoor heat exchanger that exchanges heat between the refrigerant and outdoor air and a four-way changeover valve for changeover between cooling operation and heating operation by changing the direction of flow of the refrigerant are housed in theoutdoor unit 21. Moreover, electrical components are housed in theoutdoor unit 21, and the electrical components include a power circuit of the air conditioner and acontrol part 7 constructed of a CPU. The CPU reads a control program stored in a ROM and executes control of the air conditioner. Therefrigerant piping 5 is connected to theoutdoor unit 21 and supplied with the refrigerant of prescribed temperature and pressure by changeover control of the four-way changeover valve and capacity control of the compressor. - On the other hand, a humidifying rotor formed of a moisture adsorbent material such as zeolite, an air blower to which the humidifying rotor is selectively connected to the inlet side, and a connection damper that connects the
ventilation pipe 6 to the inlet side or the outlet side of the air blower in a changeover manner are housed in thehumidifying unit 22 of theoutdoor unit 2. In a first switch position of the connection damper, theventilation pipe 6 is connected to the inlet side of the air blower, and the air blower takes in the indoor air via theventilation pipe 6 and theindoor unit 1 and discharges the air to the outside of the room. On the other hand, in a second switch position of the connection damper, theventilation pipe 6 is connected to the outlet side of the air blower, and the air blower supplies the outdoor air humidified via the humidifying rotor or the outdoor air that does not pass through the humidifying rotor into the room via theventilation pipe 6 and theindoor unit 1. - The indoor air ventilating operation is thus performed by discharging the indoor air to the outside of the room via the
indoor unit 1, theventilation pipe 6 and theoutdoor unit 2 or supplying the outdoor air into the room. That is, a ventilating part is constructed of an opening formed in the ventilation flue of the indoor unit, theventilation pipe 6 that communicates with the opening, the air blower connected to theventilation pipe 6 and the connection damper that switches the connection of theventilation pipe 6 to the air blower. - The
outdoor unit 2 further includes an information communicating part that carries out information communication between the unit and theindoor unit 1 to receive the command signal, which has been transmitted from the wirelessremote controller 3 and received by the transmitting and receiving part 13 of theindoor unit 1, from the information communicating part of theindoor unit 1. Asecond EEPROM 23 that stores the operation information at the present time of operation that the information communicating part has received from theindoor unit 1 is further provided. - The
control part 7 provided for the electrical components in theoutdoor unit 21 carries out capacity control and start/stop of the compressor, changeover of the four-way changeover valve, capacity control and start/stop of the air blower and changeover of the connection damper on the basis of the command signal from theindoor unit 1. Moreover, thecontrol part 7 controls storage and read from and to thefirst EEPROM 11, transmission and reception to and from the wirelessremote controller 3 and storage and read from and to thesecond EEPROM 23 regarding the operation information of the air conditioner. - The ventilating operation by the air conditioner of the above construction is described with reference to the flow chart of
FIG. 2 . The flow chart shows the processing executed by thecontrol part 7. - First of all, power of the air conditioner is turned on to start up the air conditioner (step S1). The
control part 7 is started up by turning on the power and determines whether or not the command signal of the contents to turn on the ventilating operation has been received from the wireless remote controller 3 (step S2). When it is determined that the command signal for turning on the ventilating operation has been received from the wirelessremote controller 3, information that represents the on-state of the ventilating operation is stored into thefirst EEPROM 11 of the indoor unit 1 (step S3). Subsequently, information that represents the on-state of the ventilating operation is stored into thesecond EEPROM 23 of the outdoor unit 2 (step S4). - Subsequently, it is determined whether the command signal from the wireless
remote controller 3 has the contents representing the on-state of the ventilating operation or the contents representing the off-state of the ventilating operation (step S5). - When it is determined that the command signal for turning on the ventilating operation is not received from the wireless
remote controller 3 in step S2, the information stored in thefirst EEPROM 11 of theindoor unit 1 is read to determine whether or not the ventilating operation has been on at the previous time of operation (step S7). When the information stored in thefirst EEPROM 11 is the information of the on-state of the ventilating operation and it is determined that the ventilating operation has been on at the previous time of operation, the program flow proceeds to the step S5. - When the information stored in the
first EEPROM 11 is the information of the off-state of the ventilating operation in the step S7, the information stored in thesecond EEPROM 23 is read to determine whether or not the ventilating operation has been on at the previous time of operation (step S10). When it is determined that the information stored in thesecond EEPROM 23 is the information of the on-state of the ventilating operation and the ventilating operation has been on at the previous time of operation, information that represents the on-state of the ventilating operation is stored into the first EEPROM 11 (step S11). Subsequently, operation information that represents the on-state of the ventilating operation is transmitted to the wireless remote controller 3 (step S12). Thereafter, the program flow proceeds to the step S5. - When the information stored in the
second EEPROM 23 is the information of the off-state of the ventilating operation in the step S10, the program flow proceeds to the step S5. - When the command signal from the wireless
remote controller 3 has the contents that represent the on-state of the ventilating operation in step S5, the ventilating operation is executed (step S6). That is, the connection damper of theoutdoor unit 2 is switched to connect theventilation pipe 6 to the inlet side or the outlet side of the air blower, and the air blower is started up. - When the command signal from the wireless
remote controller 3 has the contents that represent the off-state of the ventilating operation in step S5, it is determined whether or not the information stored in thefirst EEPROM 11 represents the on-state of the ventilating operation (step S8). When the information stored in thefirst EEPROM 11 represents the on-state of the ventilating operation, the program flow proceeds to the step S6 to execute the ventilating operation. - When the information stored in the
first EEPROM 11 is the off-state of the ventilating operation in the step S8, the ventilating operation is brought into a stop state (step S9). - After the step S6 and step S9, the program flow returns to step S2 to determine whether or not the command signal of the on-state of the ventilating operation has been received from the wireless
remote controller 3. - As described above, when the command to perform the ventilating operation is inputted to the remote controller by the operator, in the air conditioner of the present embodiment, the ventilating operation is performed in accordance with the command signal from the remote controller. Even in a case where the command to perform the ventilating operation is not inputted to the remote controller by the operator, the ventilating operation can be resumed on the basis of the information of the on-state of the operation stored in the
first EEPROM 11 or thesecond EEPROM 23 when the ventilating operation has been performed at the previous time of operation. Therefore, even when the ventilating operation is stopped by, for example, power failure, the ventilating operation identical to the operation at the previous time of operation before the power failure can be resumed at the present time of operation after recovery from the power failure even if the operator does not input the turning-on of the ventilating operation. Therefore, the conventional disadvantage that the ventilating operation cannot be resumed after recovery from power failure and brought into the stop state though no command for stopping the ventilating operation has been received can effectively be prevented. It is noted that the setting state of the air volume, wind direction and so on other than the operating state may be set back, at the present time of operation, to the initial state or to the state at the previous time of operation by storing also the setting state of the previous time of operation in thefirst EEPROM 11. - Moreover, since the signal that represents the operation information stored in the
first EEPROM 11 is transmitted to the wirelessremote controller 3 regarding the operation information of the ventilating part, the operation information can be prevented from differing between theindoor unit 1 and the wirelessremote controller 3 even when the wirelessremote controller 3 is set back to the initial state due to, for example, replacement of battery. Therefore, the disadvantage that the command signal in the initial state is transmitted to theindoor unit 1 and the operation of the ventilating part stops though no command for stopping the ventilating operation is inputted by the operator to the wirelessremote controller 3 can be prevented. - Furthermore, since backup is performed by storing the operation information to be stored in the
first EEPROM 11 of theindoor unit 1 also in thesecond EEPROM 23 of theoutdoor unit 2, the ventilating operation can be continued on the basis of the operation information stored in thesecond EEPROM 23 even if the operation information of thefirst EEPROM 11 vanishes due to, for example, the trouble or replacement of theindoor unit 1. - As described above, the air conditioner of the present embodiment can continue the execution of the ventilating operation under the power on condition until receiving the command for turning off the ventilating operation by the operator, even when power failure, trouble of the
indoor unit 1, initialization of the wirelessremote controller 3 or the like occurs. As a result, the air conditioner can function as a ventilator prescribed in the provision of Building Standard Law. -
FIG. 3 is a schematic view showing an air conditioner according to another embodiment of the present invention. - As shown in
FIG. 3 , anindoor unit 1 and anoutdoor unit 2 are connected with each other via arefrigerant piping 5, aventilation pipe 6 and aconnection wiring 8 in the air conditioner of the second embodiment as in the air conditioner of the first embodiment. - In the air conditioner of the present embodiment, operation information at the present time of operation is stored into a
third EEPROM 33 in addition to thefirst EEPROM 11 and thesecond EEPROM 23. With this arrangement, even if the operation information stored in the first and second EEPROM's 11 and 23 vanish due to the trouble of the indoor unit and the outdoor unit, replacement of electrical components or the like, ventilating operation similar to that at the previous time of operation can be performed on the basis of the operation information stored in thethird EEPROM 33. - In the present embodiment, components similar to the components of the first embodiment are denoted by the same reference numerals as those used in the first embodiment, and no detailed description is provided for them.
- In the air conditioner of the present embodiment, the wireless
remote controller 3 has thethird EEPROM 33. Operation information received from theindoor unit 1 is written into thethird EEPROM 33, and operation information to be transmitted to theindoor unit 1 is read from thethird EEPROM 33. The wirelessremote controller 3 transmits the operation information read from thethird EEPROM 33 to theindoor unit 1 in addition to the command signal corresponding to the input to the input part by the operator by means of an infrared ray transmitting and receivingpart 31 that transmits and receives an infrared signal between the controller and theindoor unit 1. Moreover, the operation information to be written into thethird EEPROM 33 is received from theindoor unit 1 by the infrared ray transmitting and receivingpart 31. The wirelessremote controller 3 further includes an input part for inputting by the operator in the room as in the case of the wirelessremote controller 3 of the first embodiment. - Moreover, the infrared ray transmitting and receiving part 13 of the
indoor unit 1 receives the operation information signal that represents the operation information stored in thethird EEPROM 33 from the wirelessremote controller 3 in addition to the command signal that issues commands of the operating mode, preset temperature, preset air volume, wind direction and so on, or the operating states of the air conditioner. Moreover, the infrared ray transmitting and receiving part 13 of theindoor unit 1 transmits an operation information signal, which represents the operation information of the air conditioner that should be stored in thethird EEPROM 33, to the wirelessremote controller 3. -
FIGS. 4A and4B are flow charts showing the processing executed in thecontrol part 7 of the air conditioner of the present embodiment. The ventilating operation of the air conditioner of the present embodiment is described with reference to the flow charts ofFIGS. 4A and4B . - First of all, the power of the air conditioner is turned on to start up the air conditioner (step S1) and start up the
control part 7, and it is determined whether or not the command signal of the contents of turning on the ventilating operation has been received from the wireless remote controller 3 (step S2). When it is determined that the command signal for turning on the ventilating operation has been received from the wirelessremote controller 3, information that represents the on-state of the ventilating operation is stored into thefirst EEPROM 11 of the indoor unit 1 (step S3). Subsequently, information that represents the on-state of the ventilating operation is stored into thesecond EEPROM 23 of the outdoor unit 2 (step S4). Further, information that represents the on-state of the ventilating operation is transmitted to the wirelessremote controller 3, and the information that represents the on-state of the ventilating operation is stored into thethird EEPROM 33 of the wireless remote controller (step S5). - Subsequently, it is determined whether the command signal from the wireless
remote controller 3 has the contents representing the on-state of the ventilating operation or the contents representing the off-state of the ventilating operation (step S6). - When it is determined that the command signal for turning on the ventilating operation is not received from the wireless
remote controller 3 in step S2, the information stored in thefirst EEPROM 11 of theindoor unit 1 is read to determine whether or not the ventilating operation has been on at the previous time of operation (step S8). When the information stored in thefirst EEPROM 11 is the information of the on-state of the ventilating operation and it is determined that the ventilating operation has been on at the previous time of operation, the program flow proceeds to the step S6. - When the information stored in the
first EEPROM 11 is the information of the off-state of the ventilating operation in the step S8, the information stored in thesecond EEPROM 23 is read to determine whether or not the ventilating operation has been on at the previous time of operation (step S11). When it is determined that the information stored in thesecond EEPROM 23 is the information of the on-state of the ventilating operation and the ventilating operation has been on at the previous time of operation, information that represents the on-state of the ventilating operation is stored into the first EEPROM 11 (step S12). Subsequently, operation information that represents the on-state of the ventilating operation is transmitted to the wirelessremote controller 3, information that represents the on-state of the ventilating operation is stored into thethird EEPROM 33 of the wireless remote controller (step S13). Thereafter, the program flow proceeds to the step S6. - When the information stored in the
second EEPROM 23 is the information of the off-state of the ventilating operation in the step S11, the wirelessremote controller 3 is commanded to read the information stored in thethird EEPROM 33 and transmit the information to the indoor unit, and it is determined whether or not the ventilating operation has been on at the previous time of operation on the basis of the information received by the indoor unit (step S14). When the information stored in thethird EEPROM 33 is the information of the on-state of the ventilating operation and it is determined that the ventilating operation has been on at the previous time of operation, the information that represents the on-state of the ventilating operation is stored into the first EEPROM 11 (step S15). Subsequently, the information that represents the on-state of the ventilating operation is stored into thesecond EEPROM 23 of the outdoor unit 2 (step S16). Thereafter, the program flow proceeds to the step S6. - When the information stored in the
third EEPROM 33 represents the off-state of the ventilating operation and it is determined that the ventilating operation has been off at the previous time of operation in the step S14, the program flow proceeds to the step S6. - When the command signal from the wireless
remote controller 3 has the contents that represent the on-state of the ventilating operation in the step S6, the ventilating operation is executed (step S7). - When the command signal from the wireless
remote controller 3 has the contents that represent the off-state of the ventilating operation in step S6, it is determined whether or not the information stored in thefirst EEPROM 11 represents the on-state of the ventilating operation (step S9). When the information stored in thefirst EEPROM 11 represents the on-state of the ventilating operation, the program flow returns to the step S7 to execute the ventilating operation. - When the information stored in the
first EEPROM 11 is the off-state of the ventilating operation in the step S9, the ventilating operation is brought into a stop state (step S10) - . After the step S7 and step S10, the program flow returns to step S2 to determine whether or not the command signal of the on-state of the ventilating operation has been received from the wireless
remote controller 3. - As described above, when the command to perform the ventilating operation is inputted to the remote controller by the operator, in the air conditioner of the present embodiment, the ventilating operation is performed in accordance with the command signal from the remote controller. Even in a case where the command to perform the ventilating operation is not inputted to the remote controller by the operator, the ventilating operation can be resumed on the basis of the information of the on-state of the operation stored in the
first EEPROM 11, thesecond EEPROM 23 or thethird EEPROM 33 when the ventilating operation has been performed at the previous time of operation. Therefore, even if the information stored in the first andEEPROM 11 and thesecond EEPROM 23 vanish due to, for example, replacement, malfunction or the like of electrical components, the air conditioner of the present embodiment can resume the ventilating operation similar to that at the previous time of operation at the present time of operation regardless of an input by the operator. - Although the information that represents the on-state of the ventilating operation is stored in the
third EEPROM 33 by receiving the command signal for turning on the ventilating operation from the wirelessremote controller 3 and thereafter transmitting the information that represents the on-state of the ventilating operation to the wireless remote controller 3 (step S5) in the second embodiment, it is acceptable to store the information that represents the on-state of the ventilating operation into thethird EEPROM 33 when the input of turning on the ventilating operation is made by the operator to the wirelessremote controller 3. In this case, the step S5 may be removed. - Moreover, when the information of the on-state of the ventilating operation is stored in the
second EEPROM 23 or thethird EEPROM 33, the information is once stored in thefirst EEPROM 11 and thereafter the ventilating operation is executed by reading the information stored in thefirst EEPROM 11 in the first and second embodiments. However, the ventilating operation may immediately be executed by reading the information of the on-state of the ventilating operation stored in thesecond EEPROM 23 or thethird EEPROM 33. - Moreover, although the
first EEPROM 11 is provided as the first nonvolatile memory for theindoor unit 1, the first nonvolatile memory needs not be provided for theindoor unit 1 but allowed to be provided for theoutdoor unit 2 or the wirelessremote controller 3. For example, it is acceptable to remove thefirst EEPROM 11 of theindoor unit 1 and make thesecond EEPROM 23 of theoutdoor unit 2 or thethird EEPROM 33 of the wirelessremote controller 3 function as thefirst EEPROM 11. - Moreover, in the first and second embodiments, ventilation means at least one of supply of outdoor air into a room and discharge of indoor air to the outside of the room. Moreover, supply of outdoor air into a room and discharge of indoor air to the outside of the room may alternately be performed on the basis of the input condition by the operator or another condition.
- Moreover, although the information of the on-state and the off-state of the ventilating operation at the previous time of operation is stored in the first, second and third EEPROM's 11, 23 and 33 in the first and second embodiments, it is acceptable to store the information of distinction between intake and discharge of air, air volume, wind direction, presence or absence of humidifying operation, preset temperature and so on of the ventilating operation besides the information of the on-state or the off-state of the ventilating operation.
- Moreover, although the
ventilation pipe 6 is connected to thehumidifying unit 22 that has the humidifying rotor in theoutdoor unit 2, theventilation pipe 6 may be connected to an air blower unit that has no humidifying rotor. - Moreover, the ventilating part may be constructed of a ventilation pipe of which one end communicates with the indoor unit and the other end is opened to the outside of the room and a fan that is provided for the indoor unit and discharges indoor air to the outside of the room or guides outdoor air to the inside of the room via the ventilation pipe.
- Moreover, the nonvolatile memory may be provided by a RAM or a magnetic recording device such as a hard disk besides EEPROM and is, in short, required to be a memory that can maintain the storage state even when the power is cut off.
- Moreover, although the air conditioner is constituted by connecting the
indoor unit 1 with theoutdoor unit 2 via theventilation pipe 6, therefrigerant piping 5 and theconnection wiring 8, it is acceptable to integrally form theindoor unit 1 with theoutdoor unit 2. - Embodiments of the invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the scope of the invention, as long as the variations are made in accordance with the following claims.
