DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control device for controlling a main air conditioner for performing cooling and heating, and a sub air conditioner such as a total heat exchanger and an air purifier.

[0002]

2. Description of the Related Art FIG. 7 shows a case where sub air conditioners such as a total heat exchanger and an air purifier are provided in addition to a main air conditioner for performing cooling and heating, etc. FIG. 1 is a block diagram showing a conventional technique for performing a control operation. The air conditioner 3 includes an outdoor unit 3a and an indoor unit 3b that constitute a main air conditioner, and a total heat exchanger 3c that is a sub air conditioner.

FIG. 8 is a block diagram showing a configuration in which a duct 31 for directly connecting the total heat exchanger 3c and the indoor unit 3b is provided in addition to the configuration shown in FIG.

[0004]

In the so-called intermediate period, there is a demand for operating the total heat exchanger 3c without performing cooling and heating by the main air conditioner. In order to meet such demands, as shown in FIG. 7, independent remote control devices 1A and 1B must be adopted for the indoor unit 3b and the total heat exchanger 3c.

When the duct 31 is provided as shown in FIG. 8, information indicating that the fan of the indoor unit 3b is operating by the adapter 32 is transmitted to the total heat exchanger 3c for the following reason. Must be communicated to

FIG. 9 shows a duct 3 as illustrated in FIG.
It is a conceptual diagram which shows the structure of the indoor unit 3b and the total heat exchanger 3c directly connected by 1, and the flow of air. The total heat exchanger 3c has an intake fan 311, an exhaust fan 312, and a total heat exchange element 313. The intake fan 311 takes in air from the outside as shown by an arrow 305, while the exhaust fan 312 takes in air from the room as shown by an arrow 306 and discharges it to the outside. Two fans 311 and 312
The heat exchange is performed in the total heat element 312 between the air flowed at the, and ventilation is performed while reducing waste of heat.

The indoor unit 3b sucks air from the room through the filter 303 by driving the fan 301,
The air is returned to the room via the heat exchanger 302. This air flow is indicated by the solid thin arrow 304. In this case, if the total heat exchanger 3c is operated, the total heat exchanger
The air sucked by the intake fan 311 into c.
It is carried to the indoor unit 3b via the duct 31, and the arrow 304
Are flowed into the room along the flow of air indicated by the arrow (solid thin line arrow 305a).

However, if the fan 301 of the indoor unit 3b
If there was no driving, the air flow indicated by the arrow 304 would not exist, and if the total heat exchanger 3c was operated in this state, air would flow from the duct 31 into the indoor unit 3b by the intake fan 311; As shown by the solid dashed line 305b, air flows from the inside to the outside of the filter 303. In this case, the dust attached to the indoor side of the filter 303 is blown out to the indoor side by driving the fan 301 of the indoor unit 3b.

In order to prevent such a situation, conventionally, an adapter 3 for transmitting the presence or absence of driving of the fan 301 to the total heat exchanger is provided.
When the fan 301 of the indoor unit 3b is not driven, the total heat exchanger 3c must be prevented from being driven by adding 2.

FIG. 10 is a conceptual diagram showing the configuration of the indoor unit 3b and the total heat exchanger 3c and the flow of air when they are not directly connected by a duct as exemplified in FIG. Total heat exchanger 3
“c” flows air drawn in from outside the room by the intake fan 311 to the room as indicated by an arrow 305c. Therefore, irrespective of whether the fan 301 of the indoor unit 3b is driven or not, even if the total heat exchanger 3c is operated, the problem described in FIG. 9 does not occur. That is, only the total heat exchanger 3c can be driven, but the remote control devices 1A and 1B are required separately from the indoor unit 3b.

The present invention has been made to solve the above-mentioned problems, and is intended to solve the problem regardless of whether the main air conditioner and the sub air conditioner are directly connected by a duct or not. It is intended to provide a technology for controlling these with a single remote control device.

BEST MODE FOR CARRYING OUT THE INVENTION

First Embodiment FIG. 1 is a block diagram schematically showing a connection relationship between an air conditioner 3 and a remote control device 1 and a configuration of a remote control device 1 according to an embodiment of the present invention. The air conditioner 3 includes a main air conditioner including an outdoor unit 3a and an indoor unit 3b that are electrically and mechanically connected to each other, and a total heat exchanger 3c that is a sub air conditioner. ing. Indoor unit 3b and duct 3
1, the air taken in from outside by the total heat exchanger 3c may be transported to the indoor unit 3b, or the total heat exchanger 3c may perform air inflow / outflow alone.

Remote control device 1 and indoor unit 3b
The total heat exchanger 3c is connected to the total heat exchanger 3c via a transmission member 2 capable of transmitting and receiving signals. Here, the line 2 may be wired or wireless (including not only radio wave communication but also optical communication such as infrared light).

The remote control device 1 includes a transmission material 2
Interface unit 101 for directly transmitting and receiving signals to and from the indoor unit 3b and the total heat exchanger 3c via the CPU, and a central processing unit (CPU) for performing various controls based on signals from the interface (I / O) 101 A central processing unit 102, a display unit (LCD) 104, for example, formed of a liquid crystal, the display of which is switched based on the central processing unit 102;
A dedicated memory (ROM) 103 holding predetermined data to be given to the CPU 2 and a central processing unit 102
Mode switch 105 for requesting control over
An operation switch 107 is provided.

FIG. 2 is a plan view showing the external appearance of the remote control device 1. In the display unit 104, characters, figures, symbols, and the like that can be displayed are all illustrated. The display unit 104 has a ventilation cleaning display unit 104a in a part thereof.

The operation switch 107 switches the operation / stop of the air conditioner 3, and the mode switch 105 switches the operation mode such as cooling / heating / ventilation.

FIG. 3 is a first flowchart showing the operation of this embodiment. In step S11, a remote control device (abbreviated as "remote controller" in the figure) 1
The predetermined information is transmitted to the indoor unit 3b and the total heat exchanger 3c. The predetermined information indicates whether or not the total heat exchanger 3c is connected, and if so, whether or not the total heat exchanger 3c and the indoor unit 3b are directly connected by the duct 31. is there. The former is transmitted from the total heat exchanger 3c to the remote control device 1. The latter example, those gills given to the indoor unit 3b or total heat exchanger 3c manually by setting such a dip switch, is transmitted to the remote control device 1.

When the information that the total heat exchanger 3c is connected is received in step S12, the central processing unit 102 causes the display unit 104 to display the ventilation cleaning display unit 104.
In step a13, "ventilation" is displayed (step S13).
Thereby, the operator of the remote control device 1 knows that the ventilation, that is, the total heat exchanger may be able to be driven. Alternatively, if the central processing unit 102 receives the information that the total heat exchanger 3c is not connected in step S12, the central processing unit 102 does not display “ventilation” on the ventilation clean display unit 104a on the display unit 104 (step S1).
4) The selection of the ventilation mode is lost (step S1)
7).

On the other hand, steps S13 to S15
It is determined whether or not the duct 31 is directly connected between the indoor unit 3b and the total heat exchanger 3c. If it is not directly connected (the mode shown in FIGS. 7 and 10), the process proceeds to step S16, where it is determined that the ventilation mode is selected (can be set), and regardless of the driving of the fan 301 of the indoor unit 3b. The total heat exchanger 3c can be driven. If it is directly connected (the mode shown in FIGS. 8 and 9), if only the total heat exchanger is operated, the above-described problem occurs. Therefore, the process proceeds to step S17 to select the ventilation mode. Disable (cannot set).

FIG. 4 is a second flowchart showing the operation of this embodiment. The operation mode is switched by the central processing unit 102 based on whether or not the ventilation mode has been set in steps S16 and S17 of the first flowchart.

Now, it is assumed that the mode numbers are given to the operation modes as follows. That is, it is "0" for air blowing, "1" for cooling, "2" for heating, and "3" for ventilation (driving only the total heat exchanger).

In step S21, it is confirmed whether or not the operation switching button has been turned ON. The mode switch 105 can be assigned to the operation switching button. O
Mode number at step S 22 when it is N is increased by 1.

Thereafter, it is determined in step S23 whether or not the ventilation mode has been selected. If there is a choice, ie the first
If step S16 has been executed in the flowchart of step (2), the process proceeds to step S24. Mode number at step S 24 is updated to "0" to mode numbers if you are increased to "4" does not correspond to the operation mode (step S26). Otherwise, the mode number is adopted.

If it is determined in step S23 that the ventilation mode has not been selected, that is, if step S17 has been executed in the first flowchart, the process proceeds to step S25. Since the ventilation mode is not selected, if the mode number is "3", step S25 is executed in step S25.
Proceed to 26, otherwise the mode number is adopted.

When each of the above-described modes of air blowing, cooling, and heating is selected, ventilation is performed at the same time. At this time, if "Y" is determined in step S15 shown in FIG. 3 (if it is determined that the duct 31 is directly connected), the total heat exchanger 3c is a fan of the indoor unit 3b. When the indoor unit 3b is driven during the operation of the indoor unit 3b when it is driven in conjunction with 301 and it is determined "N" in step S15 (when it is determined that the duct 31 is not directly connected). Is always driven.

As described above, since the availability of ventilation is determined in the remote control device 1 based on the information from the indoor unit 3b, neither an adapter nor a remote control device dedicated to the total heat exchanger is required, and the same remote control device is required. The entire air conditioner 3 can be operated by the control device 1.

Second Embodiment FIG. 5 is a conceptual diagram showing a structure in which an indoor unit 3b has a built-in type air cleaner 3d. The air purifier 3d is provided on the intake side of the indoor unit 3b, and air circulated by the fan 301 (arrow 30).
(Shown by No. 4). Therefore, even if the air purifier 3d is operated when the fan 301 stops and the air does not circulate, it hardly contributes to the indoor air purification. Therefore, when the indoor unit 3b does not operate, it is desirable to control so that the air purifier 3d does not operate.

FIG. 6 is a first flowchart showing the operation of this embodiment. The indoor unit 3b is previously provided with the air purifier 3
It has information about whether or not d is connected, and if so, whether or not d is incorporated.
This can be given to the indoor unit 3b manually by, for example, setting of a dip switch or the like, similarly to the first embodiment.

In step S31, the above information is transmitted from the indoor unit 3b to the remote control device 1. When the central processing unit 102 receives the information that the indoor unit 3b is connected in step S32, the central processing unit 102 causes the display unit 104 to display "clean" on the ventilation cleaning display unit 104a (step S33). This allows the operator of the remote control device 1 to purify the air,
That is, it is known that the air purifier 3d can be driven in some cases. Alternatively, if the central processing unit 102 receives the information that the air purifier 3d is not connected in step S32, the central processing unit 102 does not cause the display unit 104 to display "clean" on the ventilation cleaning display unit 104a (step S3).
4) The selection of the cleaning mode is lost (step S1)
7).

On the other hand, from step S33 to step S35
It is determined whether or not the air purifier 3d is a built-in type. If the air purifier 3d is not of a built-in type, it usually has its own fan, so even if it is operated independently, the indoor air purifying effect is obtained. Therefore, step S
Proceeding to 36, it is determined that the ventilation mode has been selected.

If the air purifier 3d is of the built-in type, the operation of only the air purifier 3d consumes unnecessary electric power and does not contribute to purifying the indoor air, so that the process proceeds to step S37 and the purging mode cannot be selected. To do.

The subsequent operation is the same as in the second flowchart of the first embodiment. In this case, it is sufficient that the mode number “3” is given to the air purifying mode.

As described above, whether or not cleaning is to be performed in the remote control device 1 is determined based on the information from the indoor unit 3b. Therefore, unnecessary electric power is not required in the indoor unit 3b having the built-in type air purifier 3d. The operation of the air conditioner 3 with reduced consumption can be performed by the remote control device 1.
