EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated in detail based on preferable embodiment.

1 is a perspective view showing a schematic configuration of an indoor unit of an air conditioner to which the present invention is applied. In this figure, the indoor unit 1 is installed on the side wall above the middle part in the vertical direction, the power cord is drawn from the indoor unit 1, and the plug 2 is plugged into the wall outlet. The indoor unit 1 is provided with the louver 3 which injects below the front part, and adjusts the direction of air, and the suction panel 4 which inhales indoor air above it. Further, a light receiving portion 5 for receiving an optical signal from a remote control device is provided on the lower side of the front part of the indoor unit 1 in parallel with an indicator. Although not shown in FIG. 1, an air cleaning unit constituting an electrostatic precipitator is provided between the suction panel 4 and the indoor blower provided inside.

2 is a plan view showing a schematic configuration of a remote control device of a first embodiment of an air conditioner according to the present invention. The remote control device 10 shown here has a display portion 11 on the upper side (upper side of the drawing), and an air conditioner button 12 as a first button for operating and stopping air conditioning below the display portion 11. And the air cleaning button 13 as a second button for operating the operation of the electrostatic precipitator are provided side by side, and a plurality of setting buttons including the air volume adjusting button 14 for air volume adjustment are provided in the area below.

Fig. 3 is a block diagram showing a schematic configuration of the indoor control unit of the first embodiment of the air conditioner according to the present invention, and particularly shows only elements related to the present invention. Here, the indoor controller 20 is composed mainly of the CPU 21, the light receiving unit 5, the indoor fan motor 6, the air cleaning unit 7, and the louver drive motor 8 to the CPU 21 ) Is connected. The CPU 21 receives the optical signal of the remote control device 10 from the light receiving unit 5 and controls the indoor fan motor 6, the air cleaning unit 7 and the louver drive motor 8, but the air cleaning button ( The counter 22 which counts the number of times of operation 13) or measures the elapsed time as a timer is provided.

Here, among the main operations of the indoor controller 20, particularly the parts related to the present invention will be described below. First, the air conditioning operation is started when the air conditioner button 12 of the remote control device 10 is turned on, and the air conditioning operation is stopped when the air conditioner button 12 is turned on again.

On the other hand, when the air cleaning button 13 of the remote control device 10 is turned on for the first time while the air conditioning operation is stopped, as shown in Fig. 4A, the CPU (so as to obtain the weak air in the air conditioning operation of the indoor blower) is obtained. While the 21 controls the number of rotations of the indoor fan motor 6, the CPU 21 energizes the dust collecting electrode of the air cleaning unit 7, and if the louver 3 is not downward, it is shown in Fig. 4B. As shown in the figure, the louver drive motor 8 is controlled to be downward. Thereby, a strong dust collection force is exhibited. At the time when 15 minutes have elapsed, the CPU 21 changes and controls the rotation speed of the indoor fan motor 6 so as to obtain a breeze (the smallest amount of air at the time of air conditioning operation) having a smaller amount of air than the weak air. The louver drive motor 8 is controlled so that the louver 3 faces upward. After 15 minutes have elapsed in the dust collecting state, the CPU 21 rotates the indoor fan motor 6 at a very low speed so as to obtain a super breeze state without driving sound. The state of dust collection by the ultra breeze is called ion wind operation.

As a result, in the 15 minutes immediately after the start of operation, strong dust collection is performed by the weak wind, and dust accumulated on the floor is collected at once by turning the louver 3 downward. Thereafter, the louver is directed upward, and at the same time, the amount of air is reduced to perform fine dust collection of light dust near the ceiling. In addition, after 15 minutes, energy saving and low noise operation are performed by ion wind operation.

As mentioned above, although the 1st operation | movement which operated the air cleaning button 13 ON was demonstrated, the dust collection operation separate from this is performed in the 2nd operation | movement which turned on the air cleaning button 13 once again. That is, as shown in FIG. 5, the CPU 21 controls the indoor fan motor 6 so as to obtain a super breeze normally, and continuously energizes the dust collecting electrode of the air cleaning unit 7 for the first 60 minutes only. Subsequently, the electricity supply is stopped for 10 minutes and then for 10 minutes. This is an intermittent operation after continuously performing ion wind operation, and it can be said to be an operation mode suitable for a case where low noise operation is desired from the beginning of operation in an environment where dust generation rate is low and energy saving is desired after that.

In addition, at the third time when the air cleaning button 13 is operated once again, energization to the blowing and dust collecting electrodes is stopped, that is, the operation of the electrostatic precipitator is stopped. Therefore, each time the air cleaning button 13 is turned on, the three operating states are repeated in sequence.

On the other hand, in the conventional apparatus, when the air conditioning operation is started by turning on the air conditioner button 12 during the operation of the electric precipitator, the operation of the electric precipitator, that is, the energization to the dust collecting electrode is stopped, but in the present embodiment, the air conditioning operation Even if this is disclosed, the energized state to the dust collecting electrode is continued, whereby the dust collecting operation is continued unless the air cleaning button 13 actively stops the air cleaning operation, so that both air conditioning and air cleaning are performed. The operability in the remote control device 10 in the case of performing the above is improved.

6 is a flowchart showing the specific processing procedure of the CPU 21 in the case of performing the above control. Hereinafter, a more detailed operation will be described according to the flowchart.

In the first step 101, it is determined whether there is an air conditioning operation command according to the operation of the air conditioner button 12, and if there is an operation command, it is determined in step 102 whether the electrostatic precipitator is in operation. If it is determined that the electrostatic precipitator is not in operation, the well-known air conditioning operation is executed in step 103. If the electrostatic precipitator is in operation, the process of continuing the energization state of the precipitating electrode is performed in step 104, and the step 105 or less is performed. Run the process. In step 105, it is determined whether or not there is a stop command of the air conditioning operation, and if there is a stop command, the air conditioning operation is stopped in step 106, and the energization of the dust collecting electrode is also stopped to stop the operation of the air conditioner entirely.

On the other hand, when it is determined that there is no air conditioning operation command, it is determined in step 107 whether or not the air conditioning operation is in progress, and if it is in operation, the process of step 105 or below is performed. On the contrary, if it is determined that the air conditioning operation is not in progress, the operation frequency of the air cleaning button 13 is determined in step 108 as the first, second or third time based on the operation stop state of the electric precipitator. do.

When it is determined that the number of times of operation is the first time, in step 109, the dust collecting electrode of the air cleaning unit 7 is energized, the indoor fan motor 6 is controlled so that the amount of air flows in the mild wind, and the timer is also started. Next, in step 110, the louver drive motor 8 is controlled so that the louver 3 faces downward. In step 111, it is determined whether or not the measurement time by the timer has reached 15 minutes. If 15 minutes have elapsed, the air volume is changed from mild to breeze in step 112, and the louver 3 is moved upward in step 113. Change to face. Subsequently, it is determined whether 30 minutes have elapsed in step 114, and if so, the indoor fan motor 6 is controlled to change the air volume from the breeze to the ultra breeze in step 115. As a result, the operation described with reference to FIGS. 4A and 4B is performed. Next, in step 116, it is determined whether the number of times of operation of the air cleaning button 13 is the third time, and in the third time, the air cleaning operation is stopped in step 117.

Next, when it is determined in step 108 that the operation number of the air cleaning button 13 is the second time, in step 118 the electric fan is energized to the dust collecting electrode of the air cleaning unit 7, and the indoor fan motor ( 6) and start the timer. In the next step 119, it is determined whether the measurement time by the timer has reached 60 minutes, and when it is determined that 60 minutes has elapsed, the energization of the collecting electrode is stopped in step 120, and in the next step 121, it is determined whether 10 minutes have elapsed. When it is confirmed that minutes have passed, the energization of the collecting electrode is started at step 122, and then at step 123, it is determined whether or not the energized state has elapsed for another 10 minutes. If it is determined that 10 minutes have elapsed, it is determined in step 124 whether the operation number of the air cleaning buttons 13 is the third time. If it is determined that it is not the third time, the processing of steps 120 to 124 is repeated, and if it is the third time, the air cleaning operation is stopped in step 117. As a result, the operation described with reference to FIG. 5 is performed.

If it is determined in step 108 that the number of operations of the air cleaning button 13 is the third time, the air cleaning operation is stopped in step 117.

In this way, according to the first embodiment, even if the air conditioning operation is started during the operation of the electrostatic precipitator, the air conditioning operation is performed to continue the energized state of the dust collecting electrode and to stop the energization of the collecting electrode at the same time when the air conditioning operation is stopped. The operability at the time of air cleaning operation can be improved. In addition, after a predetermined time has elapsed or at the beginning of operation in accordance with the number of times the air cleaning button 13 is operated, a quiet energy saving operation is performed, and dust collection performance can be performed even if the user does not perform a special setting operation by appropriately changing the wind direction and air volume. Can increase.

7A to 7C are explanatory diagrams showing a configuration of a second embodiment of the present invention. In the figure, Fig. 7A shows the change in the air volume, Fig. 7B shows the energized state with respect to the dust collecting electrode, and Fig. 7C shows the direction of the louver. Among these, the change in the air flow rate and the louver direction is the same as in the above-described first embodiment. In this case, the continuous energization is carried out for a very long time only at the beginning of the operation start which needs to increase the dust collection capability, and then the transition to intermittent energization is carried out in accordance with a dust-free environment. It is different from form. This enables further energy saving operation.

8A to 8C are explanatory diagrams showing a configuration of a third embodiment of the present invention. 8A shows a change in air volume, FIG. 8B shows an energized state with respect to the dust collecting electrode, and FIG. 8C shows a swing state of the louver. Among them, the air flow rate and the energized state to the dust collecting electrode are the same as in the second embodiment, but the louvers are swinging in the vertical direction only for the first 15 minutes. Thereby, the dust of the air-conditioning target space can be absorbed in every corner.

Incidentally, since it is easy for a person skilled in the art to maintain the functions of the embodiments of Figs. 7A to 7C and 8A to 8C in the CPU 21, the flowchart corresponding to this embodiment is omitted.

In this way, also in the second and third embodiments, as in the first embodiment, the operability in the case of performing the air conditioning operation and the air cleaning operation together can be improved, and the quiet energy saving operation can be performed. The dust collecting performance can be improved without any special setting operation.

As can be seen from the above description, according to the invention of claim 1, even if the air conditioning operation is started during the operation of the electrostatic precipitator, the energization state of the dust collector electrode of the dust collector is continued, and the energization of the dust collection electrode is stopped when the air conditioning operation is stopped. By stopping at the same time, it is possible to improve the operability when the air conditioning operation and the air cleaning operation are performed together, and when the electric dust collector is operated, the indoor blower is operated with ultra-mini wind and the dust collecting electrode is continuously energized for a predetermined time from the start of operation. After a predetermined time has elapsed, the transfer to intermittent energization also has the effect of enabling quiet and energy saving operation.

According to the invention according to claim 2, since the operation state of the electrostatic precipitator changes each time the air cleaning button is operated, there is an effect that the user can realize a desired dust collection state with only a single button operation.

According to the invention according to claim 3, since the air volume of the indoor blower is reduced with the passage of time, there is an effect that a quiet energy saving operation is performed after dust collection with a large dust collecting force.

According to the invention according to claim 4, since the air volume of the indoor blower is shifted to the ultra-fine wind after a predetermined time has elapsed from the start of operation, a quiet energy saving operation is performed after collecting the dust with a large dust collecting power as described above. .

According to the invention of claim 5, since the angle of the louver is changed from the downward direction to the upward direction in accordance with the decrease in the air volume of the indoor blower, the dust collecting performance can be improved even without the user making a special setting operation.

According to the invention of claim 6, since the louver is swinged until a predetermined time elapses from the start of operation, the dust in the air conditioning target space can be absorbed in every corner.
