An air blowing port is provided on the outer peripheral side of the blower 7A, and the air blowing port is connected to the air passage 5A on the front side.

In addition, the other blower 7B located on the lower side and the rear side is The configuration is almost the same as that of the blower 7A, but the motor 7D is coupled to the front side of the fan 7C. The air supply port of the blower 7B is connected to the air path 5B on the rear side. The blowers 7A and 7B are configured to blow air sucked into the axial direction by the suction port 3 to the air passages 5A and 5B, respectively. Further, in the present invention, a line flow fan may be employed as the blowers 7A and 7B.

The cleaning device 8 cleans the air taken in from the suction port 3 The apparatus constitutes a cleaning and purifying means of the present embodiment (see Figs. 2 and 4). The cleaning device 8 has, for example, a vertically long outer shape extending in the vertical direction, and is provided between the suction port 3 and the blowers 7A and 7B. Here, the term "clear purification" means to remove pollutants such as dust, smoke, pollen, viruses, molds, bacteria, allergens, and odor molecules floating in the air. Specifically, the purification device 8 captures these pollutants, making them inactive, sucking Attached to the device for decomposition. The cleaning device 8 may be composed of the following machines or a combination of the following machines: a dust collecting filter, a deodorizing filter, a voltage applying device, and the like. The dust collecting filter is a device that collects dust or the like, and the deodorizing filter is a device that adsorbs an odor component. Further, the voltage applying means is means for applying a high voltage to the electrode to remove and decompose the contaminant.

Next, referring to Figures 2 and 3, the movable grids 9A and 9B are illustrated. And the rectifying plate 13. Fig. 3 is an enlarged view of an essential part in the first diagram showing the operating states (a) and (b) of the movable grid and the rectifying plate. As shown in FIGS. 2 and 3, the movable grids 9A and 9B are means for individually adjusting the wind direction of the air blown from the air outlets 4A and 4B for the air passages 5A and 5B, and are disposed in the air outlets 4A and 4B, respectively. One. In addition, the movable grid plates 9A and 9B are formed of, for example, an elongated plate material, and extend in the left-right direction of the casing 1 in a state of being aligned in the front-rear direction. As shown in Fig. 2, the proximal end side of the movable grille plate 9A is attached to the rear end portion of the air outlet 4A through the grid drive unit 10A. Similarly, the proximal end side of the movable grid plate 9B is attached to the rear end portion of the air outlet 4B by the grid driving portion 10B.

The grid driving portion 10A is such that the movable grid 9A on the front side is up and down The device for swinging in the direction includes an actuator that supports the support shaft of the movable grille plate 9A and swings the pivot shaft (not shown). The grid drive unit 10B is a device that swings the movable grid 9B on the rear side in the vertical direction, and is configured similarly to the grid drive unit 10A. The movable grid plate 9A and the grid drive unit 10A constitute a wind direction adjustment mechanism on the front side, and the movable grid plate 9B and the grid drive unit 10B constitute a wind direction adjustment mechanism on the rear side.

The movable grids 9A and 9B are placed at the opening positions of the air outlets 4A and 4B. The wind direction causes the wind direction of the air to oscillate in the up and down direction with its swing angle. another Further, the movable grids 9A and 9B are such that the area of the flow path through which the blown air flows varies with the swing angle thereof. Specifically, for example, when the movable grille 9A is swung downward, the wind of the air blown from the air outlet 4A is inclined forward. Further, since the air passage 5A is narrowed at the position of the air outlet 4A, the flow passage area of the blown air is reduced, so the wind speed is increased. On the other hand, when the movable grid 9A is swung upward, the wind direction is changed to upward. Further, since the air passage 5A is widened at the position of the air outlet 4A, the flow passage area of the blown air is increased, so the wind speed is reduced. Similarly, when the movable grid 9B is swung, the wind direction and the wind speed of the air blown from the air outlet 4B are also changed. Further, as in the example shown in Fig. 5 to be described later, the movable grids 9A and 9B are configured to be able to close the air passages 5A and 5B (the air outlets 4A and 4B, respectively).

As shown in Fig. 2, the opening of the front side of the outlet 4A is variable. Agency 11. The opening variable mechanism 11 is a device that cooperates with the movable grid 9A to change the opening area of the air outlet 4A. The opening variable mechanism 11 is disposed, for example, at a position facing the movable grid 9A in the front-rear direction, and is swung in the front-rear direction by the opening driving unit 12. The opening drive unit 12 has almost the same configuration as the grid drive units 10A and 10B. In addition, in FIG. 1 and FIG. 3, in order to clearly show the rectifying plate 13, the illustration of the opening variable mechanism 11 is abbreviate|omitted.

The rectifying plate 13 is for maintaining the wind set by the movable grids 9A and 9B A device that changes the wind direction in the horizontal direction (left and right direction) in the state of the elevation angle. As shown in FIGS. 2 and 3, the flow regulating plate 13 is formed of, for example, a slightly triangular shape (or a fan shape). Moreover, the rectifying plate 13 protrudes from the wind receiving surface side of the movable grids 9A and 9B, and a plurality of rectifying plates 13 are disposed at intervals in the left-right direction. As shown in Fig. 3 (a) and (b), each of the flow regulating plates 13 is swung in the left-right direction so that the wind direction of the blown air changes in the left-right direction corresponding to the swing angle. In addition, the rectifying plate 13 For example, the swing is performed by the rectifying drive portion 14 (see Fig. 4) provided on the movable grids 9A and 9B, respectively. The rectifying plate 13 and the rectifying drive unit 14 constitute a specific example of the rectifying mechanism. Further, in the present invention, the opening variable mechanism 11 and the flow regulating plate 13 may not be provided.

As shown in FIGS. 1 and 2, the turning mechanism 15 is a device that is provided between the casing 1 and the susceptor 2 to rotate the casing 1 at least in the horizontal direction on the susceptor 2. The swing mechanism 15 can rotate the direction of the casing 1 and the blower outlet 4 in the horizontal direction.

Next, the control system of the air cleaner will be described with reference to Fig. 4 and the like. Fig. 4 is a view showing the configuration of a control system of the air cleaner according to the first embodiment of the present invention. The air cleaner includes a detection system including a pollution detecting device 20 and an external detecting device 21, an operation unit 22 for operating the air cleaner, and a control device 23 for controlling an operation state of the air cleaner.

The pollution detecting device 20 is a device for detecting the amount of the pollutants in the air taken in from the suction port 3, and is disposed on the upstream side of the cleaning device 8 in the air flow direction. The pollution detecting device 20 is composed of a detector which will be described later or a composite detector which is combined by a detector to be described later, for example, a dust detector, a gas detector, a wind speed detector, and the like. The dust detector is composed of a semiconductor element, an optical element, or the like, and detects the concentration of dust, smoke, pollen, and the like in the air.

The pollution detecting device 20 detects the amount of contaminant in the air that is blown out by the air cleaner in a specific direction and returns from the direction, thereby detecting the degree of contamination of the air in a specific direction. Further, the pollution detecting device 20 constitutes the pollutant detecting device of the present embodiment. The external detecting device 21 is a device that detects indoor information of a room in which the air cleaner is located. The indoor information includes: for example, whether there are people in the room, the wall to the room, the distance between obstacles and people. The control device 23 can appropriately control the wind that blows out the air based on the indoor information. Volume, wind speed and wind direction.

The control device 23 includes a calculation processing device and an output not shown. Into the 埠, and memory circuits. As shown in Fig. 4, the detection system including the pollution detecting device 20 and the external detecting device 21 is connected to the input side of the control device 23. An actuator including the blowers 7A and 7B, the purge device 8, the grid drive units 10A and 10B, the opening drive unit 12, the rectification drive unit 14, the swing mechanism 15, and the like is connected to the output side of the control unit 23. The control device 23 controls the actuator in accordance with the output of the detection system, thereby causing the air cleaner to operate.

(basic air clean action)

This is followed by a description of the basic actions of the air cleaner. When the air cleaner operates, the blowers 7A and 7B and the purge device 8 are first driven by the control device 23. Thereby, air is sucked into the inside of the casing 1 from the suction port 3, and the air is purified by the cleaning device 8. Then, the purified air is blown to the air passages 5A and 5B via the two blowers 7A and 7B, respectively. The air flowing through the air passages 5A and 5B reaches the air outlets 4A and 4B, respectively, and is blown out from the air outlets 4A and 4B. At this time, the control device 23 detects the amount of the pollutants in the air by the pollution detecting device 20, and detects the indoor information by the external detecting device 21. Then, based on these detection results and the like, the grid drive units 10A and 10B, the opening drive unit 12, the rectification drive unit 14, and the swing mechanism 15 are driven.

Thereby, the angle (elevation angle) of the wind direction of the air blown in the vertical direction is controlled in accordance with the swing angle of the movable grids 9A and 9B. Further, the wind direction angle (rotation angle) in the horizontal direction is controlled by the swing mechanism 15 and the rectifying plate 13. Further, when the swing angles of the movable grids 9A and 9B and the opening variable mechanism 11 are changed, the flow path area of the blown air is changed, so that the wind blowing the air can be controlled thereby. speed. Further, the control device 23 changes the number of revolutions of the blowers 7A and 7B to control the amount of air blown out. As described above, the air purified by the air cleaner is blown out from the air outlets 4A and 4B to the respective parts of the room. The blown air is sucked into the suction port 3 together with the pollutants in the air after being circulated indoors. By repeating this cycle action, the indoor air can be cleaned.

(wind speed increase control)

The control device 23 performs the wind speed increase control when it is necessary to increase the wind speed of the blown air. Fig. 5 is a vertical cross-sectional view showing an example of an embodiment of the wind speed increase control in the first embodiment of the present invention. As shown in this figure, in the wind speed increase control, for example, the movable side wall 9B can be closed by the movable grille 9B. Further, the wind direction of the air blown from the front side air outlet 4A can be controlled by the movable grid plate 9A and the opening variable mechanism 11. Thereby, the air flowing through the rear air passage 5B flows into the front air passage 5A through the communication hole 6. That is, the air flowing through the two air passages 5A and 5B is blown out from the single air outlet 4A, and the flow passage area of the air outlet 4 is reduced with respect to the flow rate of the blown air. Therefore, by the wind speed increase control, the communication hole 6 can be utilized to efficiently increase the wind speed of the blown air.

In addition, when the wind speed increase control is not performed, the blowout ports 4A and 4B Since both of them are open, the flow path impedance when the air flowing through the air passage 5B passes through the air outlet 4B is smaller than when passing through the communication hole 6. Therefore, when the wind speed increase control is not performed, the communication hole 6 is made to smoothly blow out the air from the respective air outlets 4A and 4B without significantly affecting the flow of the air. In addition, in the fifth figure, the case where the air passage 5B is closed is exemplified, but in the wind speed increase control of the present invention, the air passage 5B may be closed only without being closed. In this case, the air flowing through the air passages 5A and 5B can be biased toward the air outlet 4A to increase the wind speed.

In addition, most of the target air supply position is in front of the air cleaner. Therefore, in the wind speed increase control, it is preferable to close the rear side air passage 5B and blow air from the front side air passage 5A. However, in the present invention, if necessary, the air passage 5A on the front side may be closed or narrowed, and air may be blown out from the rear air passage 5B. In this case, the wind speed at which the air is blown out from the air outlet 4B can be increased. Further, in the present invention, when the rapid airflow is to be blown forward, the air passage 5B on the rear side is closed or narrowed, and when the rapid air flow is to be blown upward, the front air passage 5A is closed or closed. It narrows.

In addition, when the wind speed increase control is performed, for example, one of them is The side air path 5B is closed or narrowed, so the flow path impedance of the blown air is increased, and the pressure loss is increased. Therefore, the driving force of at least one of the blowers 7A and 7B is increased so that the amount of air blown from the air outlet 4A is kept constant. Specifically, the control device 23 increases the drive current supplied to, for example, the blowers 7A and 7B, and maintains the number of revolutions of the motor 7D constant. By this control, even when the wind speed increase control causes the opening area of the air outlet 4 to be narrowed and the pressure loss is increased, the desired air volume can be stably ensured.

Next, referring to FIG. 6, the air realized by the control device 23 will be described. The action of the cleaner. Fig. 6 is a flow chart showing an example of wind speed increase control in the first embodiment of the present invention. In the routine shown in Fig. 6, first, in step S100, when the power switch of the air cleaner is turned "ON", the control device 23 is activated. The control device 23 activates the blowers 7A and 7B and the purge device 8. Thereby, the basic air cleaning operation described above is performed.

Then, in step S101, the pollution detecting device 20 detects the null. The amount of pollutants in the gas. Then, in step S102, the pollutant is determined. Whether the amount is above the preset reference value. Here, the reference value is set corresponding to, for example, the level of pollution that must be controlled by the wind speed increase, and is stored in the control device 23 in advance. When the determination in step S102 is not satisfied, since the pollution level is such that the wind speed increase control is not performed, the processes of steps S101 and S102 are repeated and the process is awaited.

On the other hand, in the case where the determination of step S102 is established, the shift is made. Proceeding to step S103, wind speed increase control is executed. That is, in step S103, the wind direction adjusting mechanism causes one of the air passages (for example, the air passage 5B) to be narrowed. Next, in step S104, the amount of the pollutant in the air is detected as in step S101. Then, for example, when the detected amount of the pollutant is within the allowable range, it is judged that the purge of the air has ended, and the routine is terminated.

On the other hand, the detection of the pollutants detected in step S104 When the output exceeds the allowable range, the processes of steps S102 to S104 are repeatedly executed until the detected amount falls within the allowable range. According to the above procedure, when the air pollution level is high, the wind speed increase control can be performed to increase the wind speed of the air blown from the air cleaner. Thereby, the indoor air can be efficiently cleaned and the pollutants in the air can be quickly removed.

In addition, in the above procedure, the detection of pollutants is exemplified When the amount is equal to or greater than the reference value, the air passage of one of them may be narrowed. However, the present invention is not limited thereto, and may be configured such that the larger the amount of detection of the pollutants, the smaller the flow path area of one of the air passages. Thereby, the wind speed of the blown air can be changed in a continuous or stepwise manner in accordance with the amount of the pollutant. Therefore, it is possible to prevent the blowing wind speed and the indoor wind speed from becoming excessive with respect to the pollution level.

Moreover, when it is desired to increase the wind speed of the blown air, an example can be made If one of the air passages 5B is closed or narrowed, the air flow is biased toward the other air passage 5A by the communication hole 6. Thereby, compared with the case where the communication hole 6 is not provided, the flow path area of the air passage 5B can be greatly reduced, and the wind speed can be effectively increased. Therefore, even in a state where the installation area of the air cleaner is small, a high-speed air flow can be generated and the dust removal speed can be increased to efficiently purify the air.

Further, in the present embodiment, the blowers 7A and 7B are made of centrifugal wind. The fan is configured and arranged to be side by side in the vertical direction and staggered in the front and rear direction. Further, the air passages 5A and 5B are configured to extend in the vertical direction and extend upward from the blowers 7A and 7B toward the upper air outlets 4A and 4B. Thereby, the installation area of the air cleaner can be kept small when viewed from above, and two air passages 5A and 5B can be formed inside the casing 1. Further, the air blowing port is disposed on the outer peripheral side of the blowers 7A and 7B by using a centrifugal fan. As a result, the air passages 5A and 5B that are shifted in the front-rear direction can be easily connected to the air blowing ports of the blowers 7A and 7B.

Therefore, it is possible to achieve high air supply performance and in a narrow room Longitudinal air cleaners that are also easy to place. Further, in the present embodiment, the blowers 7A and 7B may be arranged side by side in the vertical direction and opened in the front-rear direction so that the blowers 7A and 7B overlap when viewed from above. In this case, for example, the lower end portion of the air passage 5B on the rear side may be bent forward in an L shape to be connected to the blower 7B. According to the above configuration, the above effects can be sufficiently obtained.

As described in detail above, in the present embodiment, it is configured to have The plurality of air passages 5A and 5B, the blowers 7A and 7B, and the movable grill plates 9A and 9B are provided with communication holes 6 between the air passages 5A and 5B. Thereby, by providing a plurality of blowers 7A and 7B, the amount of air generated per unit area of the air cleaner is increased, and the setting property can be improved. Further, when the casing 1 is rotated, the area required for the rotation becomes larger depending on the banner, the depth, and the like. When the amount of air generated per unit installation area is increased, the installation area can be miniaturized, and the area necessary for the rotation can be made small.

Embodiment 2

Next, a second embodiment of the present invention will be described with reference to Fig. 7. The present embodiment is characterized in that, in the configuration and control substantially the same as in the first embodiment, the air outlet is rotated in the horizontal direction so as to be higher toward the pollution level. Fig. 7 is a flow chart showing an example of wind speed increase control in the second embodiment of the present invention. The program shown in this figure is added to step S200 in the same processing as in the first embodiment (Fig. 6).
