Problems solved by technology

However, in this control, there is a problem that the air volume of the airflow circulating in the room increases, and the airflow comes into contact with people in the room to give people an unpleasant feeling.
[0007] On the other hand, in the prior art described in Patent Document 2, since the blowing direction of the air is controlled so that the wind does not come into contact with people in the room, there is no unpleasant feeling, but there is a problem as follows: The air is blown out in a way that avoids people, and accordingly the time required for indoor purification becomes longer

Embodiment approach 1

[0020] Figure 1 to Figure 3 The first embodiment of the present invention is shown. figure 1 Is a perspective view showing the air purifier according to Embodiment 1 of the present invention, figure 2 Is shown along figure 1 The arrow in shows the vertical cross-sectional view of the air purifier cut along the AA line. As shown in these figures, the air purifier 1 according to this embodiment includes a housing 2, a suction port 3, a blower port 4, a blower 5, a purifier 7, a wind guide 8, a control device 12, and the like. In addition, the air cleaner 1 is installed, for example, at a position close to an arbitrary wall surface in the room, and the air cleaner 1 operates with the rear surface portion of the casing 2 facing the wall surface and the front surface portion of the casing 2 facing the indoor space.

[0021] The casing 2 is formed in, for example, a quadrangular box shape, and houses the blower 5, the purification device 7, the control device 12, and the like in the ...

Embodiment approach 2

[0044] Next, refer to Figure 4 The second embodiment of the present invention will be described. Figure 4 It is a longitudinal cross-sectional view which shows the air cleaner of Embodiment 2 of this invention. As shown in this figure, the air cleaner 21 according to this embodiment is configured to be substantially the same as that of the above-mentioned first embodiment, and includes a wind guide 22. However, the air guiding device 22 is formed in the following structure: a movable body 22A attached to the open end of the air outlet 4, and a driving portion 22B that swings the movable body 22A, and an opening on the front side of the air outlet 4 No active body is configured on the end.

[0045] Even in the present embodiment configured in this way, the flow path area of ​​the air flow blown out from the air outlet 4 can be changed in accordance with the swing position of the movable body 22A, so that substantially the same effect as in the first embodiment can be obtained. ...

Embodiment approach 3

[0047] Next, refer to Figure 5 The third embodiment of the present invention will be described. Figure 5 It is a perspective view showing the air cleaner according to Embodiment 3 of the present invention. As shown in this figure, the air cleaner 31 according to this embodiment is configured to be substantially the same as that of the above-mentioned first embodiment, and includes a wind guide device 32. However, the air guide device 32 includes: two groups (4) of movable bodies composed of movable bodies 32A, 32B and movable bodies 32C, 32D; and a drive unit (not shown) that swings the movable bodies 32A, 32B, 32C, and 32D. Show).

[0048] The movable bodies 32A, 32B, 32C, and 32D are formed of, for example, a rectangular flat plate having a length of half the length of the air outlet 4 in the left-right direction of the housing 2. Furthermore, the movable bodies 32A and 32C are attached to the opening end of the front side of the blower outlet 4 in a swingable manner, and ar...

Abstract

The present invention provides an air cleaner capable of shortening the time required for indoor purification without giving unpleasant feeling to people in the room. When the air cleaner (1) is in operation, the air sucked into the housing (2) from the suction port (3) is cleaned by the purifier (7), and the air is blown out from the blower port (4). When the user of the air cleaner (1) selects a specific operation mode specifying the air volume, the control device (12) executes air volume maintenance control. In the air volume maintenance control, the air volume of the air blown out from the air outlet (4) by the air blower (5) is kept constant, and the air guide device (8) is used based on the detection state of the pollutants. The wind speed of the air changes. Alternatively, the wind speed is changed by the wind guiding device (8) and the air volume is changed by the air blowing device (5). Thereby, the dust removal efficiency can be improved without giving a feeling of blowing to people in the room, and the comfort of the user can be maintained, and the time required for cleaning the room can be shortened.

Description

Technical field [0001] The present invention relates to an air purifier having a function of purifying and blowing air taken in. Background technique [0002] As a prior art, for example, an air purifier described in Patent Document 1 is known. The prior art air purifier includes: a unit that detects the concentration of pollutants contained in the air; and a unit that controls the amount of air blown out. In addition, the air purifier monitors the concentration of pollutants while circulating the air in the room, thereby capturing the source of pollution and changing the fan strength (the amount of air blown), thereby shortening the time required for indoor purification. [0003] As another prior art, for example, an air purifier described in Patent Document 2 is also known. The air purifier detects people present in the room and controls the blowing direction of air so that the wind does not come into contact with people. Therefore, in other prior art, the wind blown from the ...
