Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner equipped with a dust collecting device equipped with a dust collecting device for collecting dust in the air and a recording medium used for the same.

[0002]

2. Description of the Related Art An air conditioner of this type has a structure in which a dust collector is arranged between a front panel and a heat exchanger or between a heat exchanger and a blower fan. There are various types of dust collectors, but recently, a system that applies a high voltage between the discharge electrode and the dust collection electrode to ionize dust in the air and attach it to the dust collection electrode, etc. Many.

However, since it is not necessary to operate the dust collector continuously, the dust collector is operated at predetermined time intervals. At this time, the rotation speed of the blower motor is automatically adjusted to increase the dust collection efficiency of the dust collector. It is made to raise.

[0004]

However, in the case of the above-mentioned conventional example, the rotation speed of the blower motor increases when the dust collector operates, so that it becomes too warm during heating, too cold during cooling, and the room temperature increases. However, there is an essential drawback that a large change occurs. That is, although the dust contained in the room air is removed and the air becomes clean, when the dust collector is operated, comfortable air conditioning cannot be obtained, and the original performance of the air conditioner is impaired.

SUMMARY OF THE INVENTION The present invention has been made in view of the above background, and an object of the present invention is to provide an air conditioner with a dust collecting device which does not greatly change the room temperature even when the dust collecting device is operated. An object of the present invention is to provide a recording medium used for this.

[0006]

In order to solve the above-mentioned problems, an air conditioner with a dust collector according to the present invention, when the dust collector is operated, increases the rotation speed of the blower motor and increases the compressor speed. The configuration includes a first operation control unit that reduces the number of rotations of the motor. There is an inverter type air conditioner.

In such a configuration, when the dust collector operates, the rotation speed of the blower motor increases, and the air flow increases. As a result, the dust collection efficiency of the dust collection device increases. On the other hand, the number of revolutions of the compressor motor decreases, and as a result, the air conditioning capacity decreases. Therefore, a change in the room temperature due to an increase in the air volume can be minimized.

More preferably, a timer for measuring the operation time of the dust collector, and when the time measured by the timer reaches a predetermined time, the dust collector is stopped and the blower motor and the compressor motor are stopped. It is desirable to include a second operation control unit that returns the rotation speed to the original state.

In such a configuration, after a predetermined operation time has elapsed after the operation of the dust collector, the dust collector stops. On the other hand, the rotation speeds of the blower motor and the compressor motor return to the original. That is, the air conditioning capacity returns to the original state.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an air conditioner with a dust collecting device according to the present invention will be described below with reference to FIGS. 1 is a block diagram of an air conditioner, FIG. 2 is a timing chart showing the output of a switch, the number of rotations of a blower motor, and the number of rotations of a compressor motor, and FIG. 3 is a flowchart of a program processed by a microcomputer.

The air conditioner described here by way of example is of an inverter type, and as shown in FIG.
0 and a switch 10 for operating the dust collector 400
0 and a microcomputer 200 that controls the entire air conditioner including the dust collector 400.

The dust collecting device 400 includes a plate-shaped dust collecting electrode 420.
And a linear discharge electrode 430, and a high-voltage circuit 410 for generating a high voltage to be applied between the two electrodes disposed opposite to each other. Here, the dust collecting electrode 420 and the discharge electrode 4
Reference numeral 30 is arranged on the back side of a heat exchanger (not shown). That is,
The high voltage generated by the high voltage circuit 410
A high electric field is generated between the two electrodes by applying a voltage between the electrodes and the discharge electrode 430, and the dust in the air sucked by the fan M2 described later is ionized and adheres to the dust collection electrode 420 and the like to collect the dust. It is configured to make it.

The switch 100 is provided on a front panel (not shown) of the air conditioner. Here, a switch of the momentary type is used. The switch 100 may be included in a remote controller attached to the air conditioner.

The switch 100 is connected to the input port of the microcomputer 200, and the compressor motor M1 and the blower motor M2 are connected to the output port via power control circuits 310 and 320, respectively. The dust device 400 is connected.

A program for controlling the compressor motor M1, the blower motor M2, the dust collector 400, and the like are recorded in the ROM 230 as a recording medium for causing the microcomputer 200 to function. This program allows the microcomputer 200 to function as the operation control unit 210 (corresponding to the first and second operation control units) and the timer unit 220. Details will be described later.

Next, a program processed by the microcomputer 200 will be described with reference to FIG. 3, and also the operation of the air conditioner with a dust collecting device will be described.

When the switch 100 is turned on while the operation switch (not shown) of the air conditioner is turned on, the dust collector 400 is operated, and the program shown in FIG. 3 is sequentially processed. First, the output of the switch 100 is checked, and it is determined whether or not this switch remains on (S1).

When the switch 100 is kept on, the current air volume is set (here, the air volume is set to three (high (H), medium (M), and lower (L) for the sake of simplicity)).
It will be described as a stage. In the case of the fully automatic mode, the setting of the air volume is automatically determined by the room temperature or the like, and in the case of the manual mode, the setting is performed through a remote controller or the like) (S2).

When the setting of the air volume is not H, it is determined whether or not it is M (S4). If it is not M, it is determined that the air volume setting is L, the setting is saved in the RAM 240 (S5), and the air volume setting is set to H (S6).
That is, the rotation speed of the blower motor M2 is increased.

Thereafter, as described above, the compressor motor M1
After the current setting of the operating frequency is saved in the RAM 240 (S7), the setting of the operating frequency is changed to a value commensurate with the air volume to lower the operating frequency (S8). That is, even if the setting of the air volume is forcibly changed from L to H, the number of revolutions of the compressor motor M1 is reduced to such an extent that the room temperature does not greatly change, and the air conditioning capacity is reduced. FIG. 2 shows the switch 1
00 is turned on at time t, and indicates a change in the rotation speed of the blower motor M2 and the compressor motor M1.

After that, the counter provided for the timer
The operation time of the dust collecting device 400 is set to, for example, 30 minutes, and the process returns to Step 1.

On the other hand, if it is determined that the air volume setting is M (S4), the setting is saved to the RAM 240 (S10), and the air volume setting is set to H (S10).
11). That is, the rotation speed of the blower motor M2 is increased.

Thereafter, the current setting of the operating frequency of the compressor motor M1 is saved in the RAM 240 (S1).
2) The operating frequency is reduced by changing the setting of the operating frequency to a value corresponding to the air volume (S13). That is, even if the setting of the air volume is forcibly changed from M to H, the number of revolutions of the compressor motor M1 is reduced to such an extent that the room temperature does not greatly change, and the air conditioning capacity is reduced.

When the switch 100 is turned on, the function of the microcomputer 200 to increase the rotation speed of the blower motor M2 and decrease the rotation speed of the compressor motor M1 is represented by an operation control unit 210 in FIG. (Corresponding to a first operation control unit).

Then, as in the case where the air volume is set to L, the timer in the microcomputer 200 is set to, for example, 30 minutes, and the process returns to step 1.

When the switch 100 returns to the original state and is turned off (S1), the data of the above-mentioned timer counter is checked to determine whether or not the value is 0 (S15). If it is not 0, the time is subtracted (here, in units of 1 minute), and then
Return to step 1 again. That is, S1, S15, and S15 until 30 minutes elapse after the switch 100 is turned on, the dust collector 400 is operated, and the air volume setting is forcibly set to H.
The process of S16 is repeatedly performed.

Thereafter, when the data of the timer counter becomes 0 (S15), the dust collector 400 is stopped, and R
The original air volume setting data saved to the AM 240 is read out, and the air volume setting is restored (S17). Similarly, the original operating frequency setting data is read out, and the operating frequency setting is restored (S18). ). As a result, the blower motor M
2, the rotation speed of the compressor motor M1 increases, and the air conditioning capacity returns to the original state. That is, the air conditioner returns to the state before the switch 100 was turned on. Thereafter, this program is terminated, and the process proceeds to a normal operation program (not shown).

The data of the timer counter substantially indicates the remaining time until the dust collector 400 is stopped, that is, the operating time of the dust collector 400. The microcomputer 20 that measures the operation time of the dust collector 400
The function 0 is shown as a timer section 220 in FIG.

When the time measured by the timer section 220 reaches a predetermined time (here, 30 minutes), the dust collector 400 is stopped, and the rotation speeds of the blower motor M2 and the compressor motor M1 are returned to the original state. The function of the microcomputer 200 of returning is also represented as the operation control unit 210 in FIG. 1 (corresponding to a second operation control unit).

On the other hand, the switch 100 is turned on (S
1) As a result of seeing the setting of the air volume (S3), the setting of the air volume is H
In this case, the rotation speed of the blower motor M2 cannot be increased more than the current time, and the dust collection capability of the dust collection device 400 is maximum. 1 and return to steps 15, 16, 1
Is repeated. When the data of the timer counter becomes 0 (S15), the dust collector 400
Is stopped, the processing of steps 17 and 18 is skipped, this program is ended, and the processing shifts to the processing of a normal operation program (not shown).

In short, when the switch 100 is turned on, regardless of the operation mode and the setting of the air volume, the dust collector 40
0 operates only for 30 minutes, and dust contained in the room is removed while performing air conditioning. In particular, when the setting of the air volume in the state where the switch 100 is turned on is M and L, the setting of the air volume is changed to H, and the dust collecting capability of the dust collecting device 400 is increased. On the other hand, since the setting of the operation frequency is changed and the operation frequency is reduced to a value corresponding to the air volume, the air conditioning capacity is reduced. After that, after the dust collection device 400 stops, the settings of the air volume and the operation frequency return to the original, and the air volume decreases, while the air conditioning capacity increases, and the operation shifts to the normal operation. As a result, even if the air volume increases due to the operation of the dust collector 400, the change in the room temperature is minimized, and a comfortable room environment is maintained.

The air conditioner with a dust collector according to the present invention is not limited to the inverter type, but may be another type. Further, the switch for operating the dust collector may not be switched manually, but may be switched automatically by a control circuit of the air conditioner. The functions of the first and second operation control units and the timer unit may be realized by hardware.

[0033]

As described above, in the case of the air conditioner with a dust collecting device according to the present invention and the recording medium used for the same, the dust collecting device operates and the rotation speed of the blower motor is increased in order to increase the dust collecting efficiency. When the air volume increases with the increase, the air conditioning capacity decreases as the compressor motor rotation speed decreases.Therefore, the indoor temperature does not change significantly when the dust collector operates, and comfortable air conditioning is realized. The original performance of the harmonic machine can be fully exhibited.
