When entering the light detection means 12 from 1), the detection distance was u2 in FIG. 20B smaller than u1.

The structure of the first conventional example has a problem that when the amount of exhaust air from the electric blower 1 increases, the wind pressure of the exhaust air impinging on the side wall n also increases, and the side wall n is contaminated. Was.

In the configuration of the second conventional example, the exhaust air discharged in the horizontal direction with the floor k reaches the human body of the person in the room j in which the air purifier body is installed. When the temperature is low, there is a problem that the chill can be sensibly felt.

In the configuration of the prior art example 3 above, when the main body of the air purifier is suspended from the ceiling, the remote control signal is transmitted from the transmitting means 10 directly below the main body of the air purifier, that is, at an angle of 90 degrees with respect to the reference line s. There is not much use in which a lighter or the like is ignited to emit light of a flame, and rather, a remote control signal is transmitted from the transmitting means 10 from a diagonally lower part of the air purifier main body, or a lighter or the like is transmitted. It is presumed that the usage state of igniting and emitting flame light will increase. For this reason, the remote control signal received by the receiving means 11 and the light of the flame such as a lighter received by the light detecting means 12 are received or received at an angle smaller than 90 degrees with respect to the reference line s. The reaching distance of the means 11 is r in FIG.

DESCRIPTION OF THE PREFERRED EMBODIMENTS (First Embodiment) A first embodiment of the present invention will be described below with reference to FIGS. The same parts as those of the conventional example are denoted by the same reference numerals, and the description thereof will be omitted.

First, the configuration of the present invention will be described.

FIG. 1 shows a control structure of the air purifier. Reference numeral 13 denotes an air flow rate detecting means for detecting an exhaust air flow rate; 14, an exhaust direction setting means for setting the direction of the louver 5; To control the exhaust direction setting means 14
Control means.

FIG. 2 shows an installation state in which the air purifier is installed on a ceiling of a corner of a room with the air inlet 2 suspended from the floor surface side. N1 is a left side wall near where the air purifier is installed, and n2 is a right side wall.

The exhaust direction is determined only by the louver 5 in FIG. 2 and does not depend on the shape of the exhaust passage 6 in FIG. The direction of the louver 5 is set by the exhaust direction setting means 14. In the present embodiment, the louvers 5 whose exhaust directions are changed by the exhaust direction setting means 14 are louvers 5a and 5b closest to the left side wall n1 and the right side wall n2, respectively. Note that the exhaust directions of all the louvers 5 may be changed,
In this embodiment, the description is omitted.

The setting of the exhaust direction of the louver 5 is as follows. The louver 5a near the left side wall n1 is set at an angle v with reference to the left side wall n1 in FIG. 2, and the angle v becomes 0 degree when the left side wall n1 and the louver 5a are parallel. The louver 5b near the right side wall n2 is shown in FIG.
An angle w is set based on the right side wall n2, and when the right side wall n2 and the louver 5b are parallel, the angle w is 0 degree.

The rotation of the electric blower 1 causes the electric blower 1
Exhaust air is generated radially from the center of rotation. Since the exhaust port 4 shown in FIG. 2 is opened at an angle of about 90 degrees, the exhaust air is also exhausted to the outside of the main body through the exhaust port 4 at an angle of about 90 degrees. Further, the exhaust air is uniformly exhausted from the exhaust port 4 which is opened at an angle of about 90 degrees, and the exhaust air pressure applied to the left side wall n1 and the right side wall n2 is the same.

FIG. 3A shows the exhaust air pressure with respect to the exhaust air volume, and FIG. 3B shows the angles of the louvers 5a and 5b. When the air volume is less than g3 in FIG. 3A, the exhaust direction setting unit 14 sets the angle v of the louver 5a in FIG. 2 to 0 degrees in FIG. 3 (a), it is defined that the angle v of the louver 5a is set to v1 in FIG. The wind pressure h3 is defined to be smaller than h2 in Conventional Example 1.

When the air volume is less than g3, the angle w of the louver 5b in FIG. 2 is set to 0 degree with respect to the right side wall n2,
When the air volume becomes g3 or more, it is defined that the angle w of the louver 5b is set to w1 larger than 0 degrees with respect to the left side wall n2. For the above-mentioned reason, since the exhaust air pressure applied to the left side wall n1 and the right side wall n2 is the same, the angle w of the louver 5b becomes the same as the angle v, and the description in FIG. 3 is omitted.

The operation of the above configuration is as follows.

When a power switch (not shown) is turned on and the operation of the electric blower 1 is started, air is exhausted from the exhaust port 4. When the amount of exhaust air is g1 in FIG. 3A, the left side wall n1 and the right side wall n2 receive the wind pressure h1. At this time, the angle v of the louver 5a is 0 degree in FIG.
Degrees.

FIG. 3 shows that the exhaust air volume increases and is larger than g1.
At g3 in FIG. 3A, the wind pressure of the exhaust air hitting the left side wall n1 and the right side wall n2 also increases and is larger than the wind pressure h1.
Receive h3 of (a).

Since the exhaust air volume has become g3, the exhaust direction setting means 14 sets the angle v of the louver 5a to v1 in FIG. 3B larger than 0 degrees and the angle w to w1 larger than 0 degrees.

Since the angle v of the louver 5a is set to v1 and the angle w of the louver 5b is set to w1, the exhaust direction of the exhaust air near the left side wall n1 and the right side wall n2 is changed from the left side wall n1 and the right side wall n2. Since it is in the direction away, the exhaust air pressure has decreased from h3 to h1 in FIG.

As described above, since the exhaust direction is set by detecting the exhaust air amount, when the exhaust air amount is small, the left side wall n
1 and the vicinity of the right side wall n2 to improve the air purification efficiency, and when the amount of the exhaust air is large, reduce the exhaust air pressure hitting the vicinity of the left side wall n1 and the right side wall n2, thereby contaminating the left side wall n1 and the right side wall n2. Can be prevented.

(Second Embodiment) Hereinafter, a second embodiment of the present invention will be described with reference to FIGS. Parts having the same configuration as the conventional example are denoted by the same reference numerals, and description thereof is omitted.

FIG. 5 shows the configuration of the installation state detecting means 16 to which the principle of the pendulum is applied. FIG. 5A is a front view of the pendulum, and FIG. 5B is a side view of the pendulum. The pendulum includes an arm 18, a weight 19 attached to one side of the arm 18, and a fulcrum 21 connecting the arm 18 to the main body connecting portion 20. 22 is the arm 18
The weightless end portion to which the weight 19 is not connected, and 23 is the lower side of the main body connection portion.

The installation state detecting means 16 is provided in the main body of the air purifier shown in FIGS.
And the bottom 7 are parallel.

Installation state detecting means 16 for the air purifier main body
Are as follows. When the air purifier is installed with the bottom 7 in contact with the floor k as shown in FIG. 6, the weight 19 hangs vertically on the bottom 7 and the weightless end 2
2 and the lower side 23 of the main body connection portion are parallel to each other, and it can be detected that the bottom 7 is installed so as to be in contact with the floor k. When the air purifier is installed so that the side 8 is in contact with the floor k as shown in FIG. 7, the weight 19 hangs perpendicularly to the side 8, and the weightless end 22 and the lower side 23 of the main body connection part. Is set to be a right angle, and it can be detected that the side portion 8 is installed so as to be in contact with the floor k.

The weightless end portion 22 and the lower side 23 of the main body connection portion
By detecting the difference between the horizontal and right angles, the installation state of the air purifier can be detected.

The exhaust direction is determined only by the louver 5 in FIGS. 6 and 7, and does not depend on the shape of the exhaust passage 6 in FIG. The direction of the louver 5 is set by the exhaust direction setting means 14. The louvers 5 whose exhaust direction is changed by the exhaust direction setting means 14 are louvers 5c and 5d closest to the bottom portion 7 and the side portion 8 in this embodiment. The exhaust direction of all the louvers 5 may be changed, but the description is omitted in this embodiment.

The setting of the exhaust direction of the louver 5 is as follows. The louver 5c near the bottom 7 is shown in FIG.
An angle x is set based on the bottom 7 and the bottom 7 and the louver 5c
Are parallel, the angle x is 0 degrees. The louver 5d close to the side 8 is set at an angle y with respect to the side 8 in FIG. 7, and the angle y becomes 0 degree when the side 8 and the louver 5d are parallel.

The rotation of the electric blower 1 causes the electric blower 1
Exhaust air is generated radially from the center of rotation. Since the exhaust port 4 in FIGS. 6 and 7 is open at an angle of about 90 degrees,
Exhaust air is also exhausted to the outside of the main body at an angle of about 90 degrees from the exhaust port 4. Exhaust air exhausted near the louver 5c near the bottom 7 is exhausted parallel to the bottom 7 and exhaust air exhausted near the louver 5d near the side 8 is exhausted parallel to the side 8.

When the air purifier is installed so that the bottom 7 is in contact with the floor k as shown in FIG. 6, the exhaust air exhausted in parallel with the bottom 7 is exhausted to the right and parallel to the side 8. Is exhausted in a direction perpendicular to the floor k. When the air purifier is installed such that the side 8 is in contact with the floor k as shown in FIG. 7, the exhaust air exhausted in parallel with the side 8 is exhausted to the left and parallel to the bottom 7. Is exhausted in a direction perpendicular to the floor k.

When the installation state detecting means 16 detects that the installation state is such that the bottom 7 of the air cleaner is in contact with the floor k, the angle x formed by the bottom 7 and the louver 5c close to the bottom 7 is determined.
Is set from 0 degree to x1, and the angle y formed by the side portion 8 and the louver 5d close to the side portion 8 is set to 0 degree.

When the installation condition detecting means 16 detects that the installation position is such that the side portion 8 of the air purifier is in contact with the floor k, the angle y formed by the side portion 8 and the louver 5d close to the side portion 8 is formed. Is set from 0 degrees to y1, and the angle x formed by the bottom 7 and the louver 5c near the bottom 7 is set to 0 degrees.

The operation of the above configuration is as follows. When the installation state detecting means 16 detects that the installation state is such that the bottom 7 of the air purifier is in contact with the floor k,
It is determined that the right horizontal exhaust is occurring, and by increasing the angle x between the bottom 7 and the louver 5c near the bottom 7 from 0 degrees to x1, the exhaust air flowing near the louver 5c near the bottom 7 is reduced. The direction is set diagonally to the upper right from the floor k, so that the exhaust air does not directly hit a person near the air purifier, thereby preventing a sensible chill.

When the installation state detecting means 16 detects that the installation is such that the side 8 of the air purifier is in contact with the floor k, it determines that the left horizontal exhaust is occurring, By increasing the angle y between the part 8 and the louver 5d near the side part 8 from 0 degrees to y1, the direction of exhaust air flowing near the louver 5d near the side part 8 is set to be diagonally upper left from the floor k, Exhaust air does not directly hit the people near the air purifier to prevent sensible cold.

As described above, since the installation state of the air purifier is detected and the angle of the louver 5 is set, the exhaust direction is different even if the installation state is different as in the second conventional example. And exhaust can be performed in almost the same direction, thereby preventing human chill.

When the air purifier is suspended from the ceiling m of the room j as shown in FIG.
An angle of 0 degree, that is, an angle p1 with respect to the floor k (FIG. 11)
It is defined to be set to enter the light detection means 12 from p1) of (b).

The operation of the above configuration is as follows. When the installation state detection means 16 detects that the air purifier is placed on the floor, the fifth control means 27 sets the detection direction of the flame light at an angle of 90 degrees with respect to the reference line s, that is, at the floor k. On the other hand, it is set so as to enter the light detecting means 12 from 0 degree (horizontal direction) (0 degree in FIG. 11A), and the detection distance is as shown in FIG.
1 (a) is the maximum u1. When the installation state detecting means 16 detects that the air purifier is suspended from the ceiling, the fifth control means 27 sets the detection direction of the flame light to the reference line s.
90 degrees, that is, the angle p1 with respect to the floor k
(P1 in FIG. 11 (b)) is set so as to enter the light detecting means 12, and the detection distance is the maximum u3 in FIG. 11 (b).

As described above, since the installation state of the air purifier is detected and the detection direction of the flame light is set, the detection distance becomes maximum (u1, u3) for each installation state. When the air purifier is suspended from the ceiling and the light of the flame enters the light detecting means 12 from the angle p1 with respect to the floor k, the detection distance is u2 in the third conventional example. In the embodiment, u3 is larger than u2, and the detection distance can be improved.

According to the first aspect of the present invention,
Since the exhaust direction is set by detecting the exhaust air volume, when the exhaust air volume is small, the exhaust air is guided to the vicinity of the side wall to improve the air purification efficiency, and when the exhaust air volume is large, the exhaust air pressure hitting the vicinity of the side wall is reduced. This can prevent the side wall from being stained.

According to the second aspect of the present invention, since the installation state of the air purifier is detected and the angle of the louver is set, the exhaust direction may be different even if the installation state is different. And exhaust can be performed in almost the same direction, thereby preventing human chill.

According to the third aspect of the present invention, since the installation state of the air purifier is detected and the receiving direction of the remote control signal is set, the reach distance becomes maximum for each installation state. Thus, the reach can be improved as compared with the case where the receiving direction is fixed.

According to the fourth aspect of the present invention, since the installation state of the air purifier is detected and the detection direction of the flame light is set, the detection distance becomes maximum for each installation state. In addition, the detection distance can be improved as compared with the case where the detection direction is fixed.
