Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an air purifier having a negative ion generating function.

[0002]

2. Description of the Related Art Conventionally, as an air purifier with a negative ion generating function, as shown in FIG.
1 and a sirocco fan 2 arranged in a casing 21
2, an air outlet 25 provided in the casing 21 and having a guide blade 25, and a negative ion generator 24 that generates negative ions and supplies them to the air flow.

[0003] According to the air purifier with the negative ion generating function having the above configuration, when the sirocco fan 22 is started,
Air flows in the direction of the dotted arrow D2. And
The air in the direction of the dotted arrow D2 is supplied with negative ions from the negative ion generator 24,
And blow it out diagonally upward.

[0004]

However, in the conventional air purifier with the function of generating negative ions, the guide blade 25 is perpendicular to the end face 27 of the outlet 23 as shown in the great circle in FIG. Therefore, air that is about to blow obliquely upward from the outlet 23 collides with the guide blade 25. Thereby, the outlet 23
The negative ions contained in the air that is about to be blown out from the air vanish due to the collision with the guide blades 25. As a result, there is a problem that the amount of negative ions of the air blown out from the outlet 23 decreases.

Accordingly, an object of the present invention is to provide an air purifier having a negative ion generating function which can increase the amount of negative ions of air blown out from an outlet.

[0006]

According to a first aspect of the present invention, there is provided an air purifier having a negative ion generating function provided in a casing, a fan disposed in the casing, and the casing. In addition, in an air purifier with a negative ion generating function including an outlet having guide blades and a negative ion generator that generates negative ions and supplies the air to the air flow, the guide blades may blow out from the outlet. It is characterized by being arranged along the direction of the wind.

According to the air purifier having the negative ion generating function of the first aspect of the present invention, when the fan is started, the air from the fan flows toward the outlet. Then, the negative ion generator supplies negative ions to the air flowing toward the outlet. The air containing the negative ions is blown out of the casing from the outlet. At this time, since the guide blades are arranged along the direction of the wind to blow out from the outlet, the air to blow out from the outlet does not collide with the guide blades, and It flows smoothly along. As a result, the negative ions do not disappear at the outlet as in the conventional example of FIG. 2, and the amount of negative ions in the air blown out from the outlet can be increased.

According to a second aspect of the present invention, there is provided an air purifier with a negative ion generating function according to the first aspect, wherein the guide blades are slanted with respect to an end face of the outlet. It is characterized by being inclined.

Thus, the air that is about to be blown out from the outlet flows smoothly along the guide blade without colliding with the guide blade. As a result, the negative ions do not disappear at the outlet, and the amount of negative ions in the air blown out from the outlet can be increased.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an air cleaner having a negative ion generating function according to the present invention will be described in detail with reference to the illustrated embodiments.

FIG. 1 is a schematic front view of a floor-standing type air cleaner having a negative ion generating function according to an embodiment of the present invention. In FIG. 1, a cross section of a portion surrounded by a small circle is schematically shown in an enlarged view within a great circle.

As shown in FIG. 1, the air purifier with a negative ion generating function includes a casing 1 and a sirocco fan 2 disposed in the casing 1. The casing 1 is provided with an outlet 3 having a plurality of guide blades 5. In addition, the sirocco fan 2
Has a scroll 6 and an impeller (not shown) accommodated in the scroll 6. A negative ion generator 4 is provided in the scroll 6.
The negative ion generator 3 generates negative ions and supplies them to the air flow.

The guide blades 5 are arranged along the direction of the wind to be blown out from the outlet 3, ie, along the direction of the dotted arrow D1. Specifically, the guide blade 5
Is inclined, for example, by 75 ° with respect to the end face 7 of the outlet 3 as shown in the great circle.

According to the air purifier having the negative ion generating function having the above-described structure, the impeller of the sirocco fan 6 rotates, so that air from the impeller flows in the direction of the dotted arrow D1. Then, the negative ion generator 4 supplies negative ions to the air flowing in the direction of the dotted arrow D1. The air containing the negative ions is blown out of the casing 2 from the outlet 3 in the direction of the solid arrow. At this time, since the guide blades 5 are arranged along the direction of the dotted arrow D1, the outlet 3
The air that is about to blow out flows smoothly along the guide blade 5 without colliding with the guide blade 5. as a result,
The negative ions do not disappear at the outlet as in the conventional example of FIG. 2, and the amount of the negative ions of the air blown out from the outlet 3 can be increased.

By the way, in the conventional air purifier with the function of generating negative ions shown in FIG. 2, the amount of negative ions of the air blown out from the outlet 23 was 290,000 / cc.
On the other hand, in the air purifier with the negative ion generating function of the above embodiment, the amount of negative ions of the air blown out from the outlet 3 was 540,000 / cc. In this way, the present issuer has confirmed that the amount of negative ions of the air blown out from the outlet 3 is increased as compared with the conventional air purifier with the negative ion generating function of FIG.

In the above embodiment, a floor-standing type air purifier having a negative ion generating function has been described as an example of the air purifier having a negative ion generating function of the present invention. It is not limited to an air purifier with a generating function.

Although the sirocco fan 2 is arranged in the casing 1, a fan other than the sirocco fan may be arranged.

Although the negative ion generator 6 is provided inside the scroll 6, it may be provided outside the scroll 6. That is, the negative ion generator may be installed anywhere as long as negative ions can be supplied to the airflow in the direction of the dotted arrow D1.

Although the guide blade 5 is inclined at an angle of, for example, 75 ° with respect to the end face 7 of the outlet 3, it is needless to say that the inclination of the guide blade 5 with respect to the end face 7 of the outlet 3 is not limited to 75. In short, the guide blades may be arranged along the direction of the wind to be blown out from the outlet 3.

[0020]

As is apparent from the above description, the air purifier with the negative ion generating function according to the first aspect of the present invention is such that the guide blades are arranged along the direction of the wind to be blown out from the outlet. Therefore, the air to be blown out from the outlet does not collide with the guide blade and loses the negative ions, and the amount of the negative ions in the air blown out from the outlet can be increased.

In the air purifier with the negative ion generating function according to the second aspect of the present invention, since the guide blades are obliquely inclined with respect to the end face of the outlet, the air to be blown out of the outlet is guided by the guide blades. And the negative ions are not lost by colliding with the air, and the amount of negative ions of the air blown out from the outlet can be increased.
