  As shown in FIG. 2, the air purification device 11 with a blowing function includes a suction port 14 that takes air into the housing 12, an air purification filter 15 that purifies the air that is attached to the suction port 14 and that is taken in, and FIG. 4. As described above, a high-pressure air generator 18 composed of an impeller 16 for generating high-pressure air and a motor 17 for driving the impeller 16, and a plurality of equal lengths erected from one surface of the housing 12. The nozzle 13 (five in this embodiment) and the duct 20 (four in this embodiment) are provided. In this embodiment, the housing 12 is erected from the upper surface.

  As shown in FIG. 2, the side of the nozzle 13 is provided with an outlet 19 for blowing out the high-pressure air generated by the high-pressure air generator 18 in one direction perpendicular to the direction in which the nozzle 13 is erected. ing. Between the plurality of nozzles 13, a duct 20 for guiding the high-pressure air generated by the high-pressure air generator 18 to the chamber 27 is provided. The nozzles 13 and the ducts 20 are alternately arranged. As shown in FIG. 3, the air that has passed through the duct 20 from the high-pressure air generator 18 is directed to the chamber 27 and from the chamber 27 to the nozzle 13.

  Also, as shown in FIG. 4, a space in which high-pressure air generated by the high-pressure air generator 18 is divided into the nozzles 13 and the ducts 20 between the high-pressure air generator 18 and the plurality of nozzles 13 and the plurality of ducts 20. 21 is provided.

In the nozzle 13 and the duct 20, a cross section perpendicular to the direction in which the nozzle 13 is raised is vertically long in the blowing direction. The plurality of nozzles 13 and the duct 20 are arranged with a gap therebetween.
The gap between the nozzle 13 and the duct 20 forms an air attraction air passage 22 that is attracted by the airflow blown from the air outlet 19. In the example of the present embodiment, five nozzles 13 and four ducts 20 are provided in the number of the induction air passages 22. Eight, which is less than the total of 20 of 9, can be formed.

  The length of the gap is preferably not less than the width of the nozzle 13 and not more than half of the length of the nozzle 13 in the standing direction from the upper surface of the casing 12 in order to obtain uniform wind speed. In the embodiment, as an example, the width of the nozzle 13 is 75 mm, the length of the nozzle 13 in the standing direction is 4000 mm, the length of the gap is 120 mm, and the length of the nozzle 13 in the blowing direction is 460 mm.

  The air purification filter 15 can be a known deodorizing filter such as a dust collection filter or activated carbon. The air that has passed through the air purification filter 15 is supplied to the impeller 16 as purified air from which dust, pollen, allergens, and the like have been removed.

  According to such a configuration, when the air cleaning device 11 with the air blowing function is operated, the motor 17 is driven and the impeller 16 rotates, so that the indoor air flows from the suction port 14 as shown in the internal flow 23. After being taken into the air purifier 11 with the air blowing function and cleaned of dirt such as dust and smell by the air purifying filter 15, it passes through the impeller 16 and reaches the space 21. In the space 21, the high-pressure air is divided into a plurality of nozzles 13 and ducts 20, passes through the chambers 27 from the nozzles 13 and the ducts, and blows out from the outlet 19 to become a blown air flow 25. Further, as shown in FIG. 1, the blown air flow 25 attracts air outside the induction air passage 22 and the outermost nozzle 13 to become an induction air flow 26. The blown air flow 25 and the induced air flow 26 blow air having a substantially uniform wind speed over a wide range.

  As a result, the air coming out from the upper air outlet is increased, the air attracted by the air velocity uniformed at the upper and lower air outlets is also made uniform in the vertical direction, and the upper air volume does not drop even if the height of the device is increased A uniform air volume can be produced vertically.

  In addition, as shown in FIG. 2, the wind direction in the standing direction of the nozzle 13 is adjusted by providing a wind direction adjusting rib 24 for adjusting the wind direction in the standing direction of the nozzle 13 in the vicinity of the air outlet 19 in the nozzle 13.

When the housing 12 is arranged on the floor surface so that the chamber 27 is on the ceiling side, the wind that blows out becomes horizontal with respect to the floor surface, can provide a uniform wind, and is comfortable for the user.

  The nozzle 13 is arranged with a gap so that the air outlet 19 is flush, so that the air flow to be blown becomes a surface air flow, and the uniformity of the wind speed is defined by the air flow 25 and the induced air flow 26 described later. It pays attention to the wind speed distribution of the merged surface airflow, and indicates that the wind speed distribution observed on a plane viewed from the front at a predetermined distance from the air outlet 19 is within a predetermined range. That is, the minimum wind speed on the plane is allowed to be at least half of the maximum wind speed. Moreover, high pressure air shall show the air above atmospheric pressure.

  In addition, in this Embodiment, the form of the air purification apparatus 11 with a ventilation function provided with the air purification filter 15 was demonstrated. The air purification filter 15 is not essential as a blower.

Further, since the suction port is formed in the vicinity of the floor, the air purification filter 15, the impeller 16, and the motor 17 can be easily replaced and cleaned.
