DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner having an outdoor unit and an indoor unit provided with a test operation switch for instructing a test operation. More specifically, the present invention relates to a stop switch provided in an outdoor unit. The present invention relates to an air conditioner that stops a test run when is operated.

[0002]

2. Description of the Related Art An operation test after an air conditioner is installed,
In order to facilitate the operation test when the repair is completed, a test operation mode is provided in which the output of the compressor is maximized and the cooling operation is performed irrespective of the operation setting conditions and the ambient temperature. This test operation mode is used not only for the above-mentioned operation test but also for recovery of CFC gas. That is, when the CFC is to be recovered in the outdoor unit, the compressor is operated at the maximum output by operating the trial operation switch of the indoor unit. In this state, the valve on the discharge side of the outdoor unit is closed, and the fluorocarbon gas dispersed in the indoor unit and the piping is collected by the outdoor unit. When all of the CFC gas is collected in the outdoor unit, the operation of the compressor is stopped by closing the valve on the suction side and then operating the trial operation switch of the indoor unit (first conventional example). Technology).

Further, in order to efficiently perform a trial run, a conventional technique in which a trial run switch is provided on the outdoor unit side is disclosed in Japanese Patent Laid-Open No. Hei 5-2.

However, when the above technique is used, the following problems have occurred. That is, in the first related art, it takes time to move from the installation location of the outdoor unit to the installation location of the indoor unit after the valve on the suction side is closed and before the operation of the compressor is stopped. On the other hand, when the valves on both the discharge side and the suction side are closed, the load on the compressor becomes extremely large, so that the compressor operating at the maximum output has a high temperature rise. Therefore, when the installation location of the indoor unit and the installation location of the outdoor unit are far apart, it takes a long time before the test run switch is operated after the valve on the suction side is closed. The machine had an excessive temperature rise.

[0005] In the second prior art, when a test run switch on a control panel provided on the outdoor unit side is operated, a test run is started. Therefore, when it is necessary to confirm the operation state of the indoor unit after installation, such as a general household air conditioner, move to the outdoor unit side, operate the test run switch, and then return to the indoor unit side. However, since it is necessary to confirm the operation of the indoor unit, the trial operation is a time-consuming operation.

An object of the present invention is to provide an outdoor unit of an air conditioner in which an indoor unit is provided with a test run switch.
An object of the present invention is to provide an air conditioner capable of stopping a trial operation on the side of an outdoor unit by providing a stop switch for stopping a trial operation without increasing the time and effort for the trial operation.

Another object of the present invention is to add an additional signal line for the stop switch by notifying the operation of the stop switch to the indoor unit via a communication line. It is to provide an air conditioner that can perform the operation.

An object of the invention according to claim 3 is, in addition to the above object, to notify the indoor unit of the operation of the stop switch by opening a connection of a power supply line to a compressor or a fan motor. An object of the present invention is to provide an air conditioner that does not require an additional signal line for a stop switch.

Another object of the present invention is to provide an air conditioner in which a stop switch is provided on a power supply line having a small current value so that the stop switch can be downsized. It is in.

According to a fifth aspect of the present invention, in addition to the above object, when the operation time of the stop switch is longer than a predetermined time, the test operation is stopped. An object of the present invention is to provide an air conditioner capable of reducing a stoppage rate.

According to a sixth aspect of the present invention, in addition to the above object, an air conditioner capable of preventing unnecessary operation of the stop switch by providing a stop switch inside the housing of the outdoor unit. To provide.

According to a first aspect of the present invention, there is provided an air conditioner comprising an outdoor unit and an indoor unit provided with a test operation switch for instructing a test operation. When the switch is operated, the present invention is applied to an air conditioner that performs a test run, and the outdoor unit is provided with a stop switch for instructing a stop of the test run. The test run is stopped when operated. That is, when the test operation switch provided in the indoor unit is operated, the test operation is started, so that the operation check of the indoor unit becomes easy. When the stop switch provided on the outdoor unit is operated, the test operation is stopped.

In the air conditioner according to the present invention, the indoor unit and the outdoor unit are connected via a communication line, and the indoor unit is connected to the outdoor unit via the communication line. Applied to an air conditioner that controls the operation, the outdoor unit notifies the indoor unit via the communication line that the stop switch has been operated, and the indoor unit indicates that the stop switch has been operated. When notified, via the communication line,
It is configured to instruct the outdoor unit to stop the trial run.
That is, the operation of the stop switch is transmitted from the outdoor unit to the indoor unit via the communication line provided for the indoor unit to control the outdoor unit.

Among the types of power supply lines, a current detector for detecting the current of the power supply line that is opened by the stop switch is provided, and in the indoor unit, the current value detected by the current detector is smaller than a predetermined value. In some cases, the trial operation of the outdoor unit is stopped assuming that the stop switch is operated. That is, when the stop switch is operated in the test operation state, the current of the power supply line provided with the stop switch decreases (for example, becomes 0). The decrease in the current of the power supply line is detected by a current detector on the indoor unit side. That is, the operation of the stop switch is transmitted from the outdoor unit to the indoor unit via the power supply line provided with the stop switch.

According to a fourth aspect of the present invention, in addition to the above configuration, the stop switch opens a connection of the fan motor power supply line, and the current detector includes

The test operation switch 13 is a switch attached to a position where the operation can be performed when a front grill (not shown) of the indoor unit main body is opened, and the start and stop of the test operation are transmitted to the indoor control unit 12. Used to direct. In addition, the indoor control unit 1
Reference numeral 2 denotes a block that controls the main operation of the air conditioner, and controls the operation of the indoor mechanism unit 11. The operation of the outdoor unit 2 is controlled by sending an instruction to the outdoor unit 2 via the communication line 31. For this reason, when the test operation switch 13 is operated, the indoor control unit 12 causes the indoor mechanism unit 11 to perform an operation corresponding to the test operation and gives an instruction via the communication line 31 to perform the operation corresponding to the test operation. Is performed by the outdoor unit 2.

The outdoor mechanism 21 provided in the outdoor unit 2 includes:
Refrigerant mechanism 24, compressor 25, and fan motor 2
It is a block composed of 6 mag. Further, the refrigerant mechanism section 24 is a block including a heat exchanger, a four-way valve, and the like. For this reason, during the cooling operation, the outdoor mechanism section 21 compresses the chlorofluorocarbon gas as the refrigerant and cools the compressed chlorofluorocarbon gas. Then, the cooled Freon gas is discharged to the indoor mechanism 11. Further, during the heating operation, the indoor mechanism 1 is made to pass through the heat exchanger.
The heat is absorbed by the Freon gas refluxed from 1. And
The fluorocarbon gas that has absorbed the heat is compressed and discharged to the indoor mechanism unit 11.

The stop switch 23 is used to stop the test operation via the outdoor controller 22 and the communication line 31 via the indoor controller 12.
Switch to instruct the user. Further, the outdoor control unit 22 is a block for operating the outdoor mechanism unit 21 in accordance with an instruction sent from the indoor control unit 12. Also, during the test run, the stop switch 23
Is operated, and when it is detected that the continuation time of the operation exceeds, for example, 3 seconds, a signal indicating the operation of the stop switch 23 (hereinafter, referred to as a stop signal) is transmitted via the communication line 31 to the room. It is sent to the control unit 12.

FIG. 3 is an explanatory view showing an attachment position of the stop switch 23. In FIG. 3, reference numeral 33 denotes a housing of the outdoor unit 2. In addition, an inner panel 34 that is obliquely inclined is provided inside the housing 33. In addition, a shield plate 35 that can be opened and closed is attached to an opening formed at a position corresponding to the front of the inner panel 34. The stop switch 23 is attached to the internal panel 34. Therefore, the stop switch 23 is a switch that is not likely to be operated unless the shielding plate 35 is opened. The stop switch 23 is connected to the knob 2
The switch is turned on only during a period in which the key 31 is pressed.

FIG. 4 is a flowchart showing the main operation of the indoor unit 1, and FIG. 5 is a flowchart showing the main operation of the outdoor unit 2. The operation of the first embodiment will be described with reference to FIG.

The operation of a normal test run is as follows. That is, it is assumed that the test operation switch 13 has been operated to start the test operation (step S1). The indoor control unit 12 that has detected the operation of the trial operation switch 13 issues an instruction to start the trial operation via the communication line 31 to the outdoor control unit 2.
Send to 2. In addition, the indoor mechanism section 11 is caused to perform an operation corresponding to the test operation (step S2). On the other hand, when the instruction for the trial operation is given, the outdoor control unit 22 sets the refrigerant mechanism unit 24 to the cooling mode. Also, the compressor 25
Is operated at the maximum output, and the fan motor 26 is rotated at the maximum speed (steps S8 and S9).

After starting the test operation, the indoor control unit 12
Checks whether the test run switch 13 is operated and also checks whether a stop signal is sent from the outdoor control unit 22 (steps S3 and S4). Therefore, when the test operation switch 13 is operated during the test operation period, the operation shifts from step S3 to step S5. As a result, the indoor control unit 12 sends an operation stop instruction to the outdoor control unit 22. Further, the operation of the indoor mechanism unit 11 is stopped (Step S5).

After starting the control corresponding to the trial operation, the outdoor control unit 22 checks whether or not an instruction to stop the operation is sent from the indoor control unit 12 and checks the stop switch 2
It is checked whether or not 3 has been operated for longer than 3 seconds (steps S10, S11). Therefore, when the operation stop instruction is sent from the indoor control unit 12, the outdoor control unit 22 shifts the operation from step S10 to step S14, and stops the operation of the compressor 25 and the fan motor 26.

On the other hand, since it is necessary to remove the air conditioner due to moving or the like, the operation as described below is performed when the fluorocarbon gas is collected in the outdoor unit 2.

When the trial run switch 13 is operated, the indoor control unit 12 sends an instruction to start the trial run to the outdoor control unit 22. In addition, the indoor mechanism section 11 is caused to perform an operation corresponding to the test operation (steps S1 and S2). On the other hand, when the instruction for the trial operation is given, the outdoor control unit 22 sets the refrigerant mechanism unit 24 to the cooling mode. Compressor 2
5 is operated at the maximum output, and the fan motor 26 is rotated at the maximum speed (steps S8 and S9).

After starting the test operation, the indoor control unit 12
Checks whether the test run switch 13 is operated and also checks whether a stop signal is sent from the outdoor control unit 22 (steps S3 and S4). Further, after the outdoor control unit 22 causes the outdoor mechanism unit 21 to start the operation corresponding to the trial operation, the outdoor control unit 22 checks whether an operation stop instruction is transmitted from the indoor control unit 12, and determines whether the stop switch 2
It is checked whether or not 3 has been operated for longer than 3 seconds (steps S10, S11).

In the above-described test operation, the chlorofluorocarbon gas was supplied to the outdoor unit 2.
Therefore, the valve 28 on the discharge side is closed during the test operation. As a result, the fluorocarbon gas dispersed in the indoor mechanism section 11 and the piping starts to be collected in the outdoor mechanism section 21. Then, when the fluorocarbon gas is collected in the outdoor unit 2, the valve 27 on the suction side is closed. Then, after the valve 27 is closed, the knob 231 of the stop switch 23 is pressed for more than 3 seconds. Therefore, the operation moves from step S11 to step S12. Therefore, the outdoor control unit 22 sends a stop signal to the indoor control unit 12.

When a stop signal is sent from the outdoor control unit 22, the indoor control unit 12 shifts the operation from step S4 to step S5, and performs control to stop the trial operation. That is, the indoor control unit 12 stops the operation of the indoor mechanism unit 11. In addition, an operation stop instruction is sent to the outdoor control unit 22. Therefore, the outdoor control unit 22 stops the operation of the compressor 25 and the fan motor 26 according to the operation stop instruction sent from the indoor control unit 12 (Step S13,
S14).

If the knob 231 of the stop switch 23 is erroneously depressed during the test operation for collecting the chlorofluorocarbon gas into the outdoor mechanism 21, if the depressed time is shorter than 3 seconds, the outdoor control is performed. The unit 22 performs step S
Only the loop operation of S10 and S11 is repeated, and no stop signal is sent. Therefore, even when the stop switch 23 is operated erroneously, the test operation is continued if the operation time is shorter than 3 seconds.

The configuration of the outdoor control unit 22 is such that when the stop switch 23 is turned on from off, a signal indicating that it has changed from off to on is sent to the indoor control unit 12 and turned off from on. Sometimes, a signal indicating that the state has changed from on to off is transmitted to the indoor control unit 12, and the indoor control unit 12 may determine whether the stop switch 23 has been continuously operated for 3 seconds or more. Good.

FIG. 2 is a block diagram showing an electric configuration of an air conditioner according to a second embodiment of the present invention, which is roughly divided into an indoor unit 4 provided with a test operation switch 43,

The refrigerant mechanism 54 provided in the outdoor unit 5 includes:
The block is provided with a heat exchanger, a four-way valve, and the like. For this reason, during the cooling operation, the outdoor unit 5 compresses the CFC, which is a refrigerant, using the compressor 55 and cools the compressed CFC in the refrigerant mechanism 54. Then, the cooled chlorofluorocarbon gas is supplied to the indoor mechanism 41.
To be discharged. In the heating operation, the refrigerant flows through the heat exchanger of the refrigerant mechanism 54 to absorb the heat in the CFC gas flowing back from the indoor mechanism 41. Then, the fluorocarbon gas having absorbed the heat is compressed and discharged to the indoor mechanism section 41.

The stop switch 53 is a switch for opening a connection of a power supply line 76 for supplying power to the fan motor 56. In detail, the stop switch 53 is a switch whose connection is closed when not operated, and only when the power supply line 7 is operated.
Open connection 6. The mounting position is the same as that of the stop switch 23 shown in FIG.
It is 4. Therefore, the stop switch 53 is a switch that is not likely to be operated unless the shielding plate 35 is opened.

The indoor unit 4 and the outdoor unit 5 have the above-described configuration. Therefore, when the test operation switch 43 is operated, the main control unit 42 causes the indoor mechanism unit 11 to perform an operation corresponding to the test operation. Further, the compressor 55 and the fan motor 56 are operated by closing the connection of the switches 45 and 46. Further, if the stop switch 53 is operated for more than 3 seconds during the test operation, the period during which the output of the current sensor 44 becomes equal to or less than the predetermined value becomes longer than 3 seconds. If the period of time below the predetermined value is longer than 3 seconds,
The main control unit 42 determines that the stop switch 53 has been operated, and performs control to stop the test operation. That is, the main control unit 42 opens the connection of the switches 45 and 46 and stops the operation of the compressor 55 and the fan motor 56. Further, the operation of the indoor mechanism unit 41 is stopped.

FIG. 6 is a flowchart showing the main operation of the second embodiment. The operation of the second embodiment will be described with reference to FIG.

The operation of a normal test run is as follows. That is, it is assumed that the trial run switch 43 has been operated to start the trial run. The main control unit 42 that has detected the operation of the trial operation switch 43 causes the indoor mechanism unit 41 to perform an operation corresponding to the trial operation. Further, the operation of the compressor 55 and the fan motor 56 is started (steps S21 and S21).
22). After the start of the test run, the main control unit 4
2 checks whether the test run switch 43 is operated or not, and determines whether the current value indicated by the output of the current sensor 44 is
It is checked whether it becomes 0 in 3 seconds (step S
23, S24). Therefore, when the test operation switch 43 is operated during the test operation period, the operation is performed in step S2.
Then, control goes from step 3 to step S25. Therefore, the main control unit 4
Step 2 stops the operation of the compressor 55 and the fan motor 56 and stops the operation of the indoor mechanism 41.

On the other hand, since it is necessary to remove the air conditioner due to moving or the like, the operation will be as follows when the fluorocarbon gas is collected in the outdoor unit 5.

When the test run switch 43 is operated, the main control section 42 causes the indoor mechanism section 41 to perform an operation corresponding to the test run. Further, the operation of the compressor 55 and the fan motor 56 is started (steps S21 and S22). And
After starting the test run, the main control unit 42 checks whether or not the test run switch 43 is operated, and when the current value indicated by the output of the current sensor 44 becomes 0 in 3 seconds.
It is checked whether or not (steps S23 and S24).

Since the test operation at this time is a test operation for collecting the chlorofluorocarbon gas into the outdoor unit 5, the valve 58 on the discharge side is closed during the test operation. As a result, the fluorocarbon gas dispersed in the indoor mechanism section 41 and the pipes starts to be collected in the outdoor unit 5. And, CFC gas is used for outdoor unit 5
, The suction-side valve 57 is closed. Then, after the valve 57 is closed, the stop switch 53 is pressed for more than 3 seconds. Therefore,
The current value of the power supply line 76 becomes 0 during a period longer than 3 seconds. Therefore, the operation moves from step S24 to step S25. Therefore, the main control unit 42 stops the operation of the compressor 55 and the fan motor 56,
The operation of the indoor mechanism 41 is stopped.

In order to collect Freon gas in the outdoor unit 5, the stop switch 53 is erroneously set during trial operation.
Is operated, if the operation time is shorter than 3 seconds, the main control unit 42 only repeats the loop operation of steps S23 and S24, and does not stop the test operation. Therefore, even when the stop switch 53 is operated erroneously, the test run is continued if the operation time is shorter than 3 seconds.

Although the case where the stop switch is provided on the power supply line 76 has been described, the stop switch is provided on the power supply line 75 for the compressor 55 (in this case, the current sensor is connected to the power supply line 75). Or a configuration provided on a common power supply line 74 for the compressor 55 and the fan motor 56 (in this case, the current sensor is an arbitrary power supply line of the power supply lines 74 to 76). May be configured to detect the current).
