When the driving gear 52 is rotated by the electric motor 53 disposed on the upper side of the humidifying filter 50, the driving force is transmitted to the driven gear 55, and the humidifying filter 50 and the holding frame 54 are rotated. As the humidifying filter 50 rotates, the portion immersed in the water receiving tray 51 sequentially moves in the circumferential direction to suck up water, and the entire humidifying filter 50 is in a state of containing moisture. As a result, the air that has passed through the humidifying filter 50 is humidified. On the other hand, when the humidifying filter 50 is not rotating, the air that has passed through the humidifying filter 50 hardly absorbs moisture.

The first blower 13 includes a fan motor 131 and a fan 132, and the fan motor 131 rotationally drives the fan 132. The fan 132 is a multi-blade impeller having a plurality of blades whose rotation center side is displaced in the rotation direction with respect to the outer edge, in other words, a sirocco fan having a cylindrical shape. The fan motor 131 is fixed to the outside of the wall of the blowing air passage 3b. The fan 132 is fixed to the output shaft of the fan motor 131 and is disposed opposite to the opening 31 a below the partition wall 31. When the fan 132 rotates, outside air is introduced into the filter housing portion 3a through the suction port 33 and flows forward in the filter housing portion 3a as shown by the white arrow in FIG. The air is sucked into the fan 132 through the opening 31 a below the partition wall 31. The air sucked into the fan 132 changes its direction upward and is led out into the blowout air passage 3b, and is sent to the outside through the air outlet 34 at the end of the blowout air passage 3b.

Further, in the blowout air passage 3b, the air passage wall surfaces 36a and 36b for guiding the air from the fan 132 to the air outlet 34 are arranged so as to be inclined from the front lower side to the rear upper side, and the wind direction provided in the air outlet 34 The restricting

plates

37, 37,... Are also inclined so as to incline from the front lower side to the rear upper side. Thereby, the 1st ventilation path 3 blows off air from the blower outlet 34 toward back diagonally upward direction. Note that the air blown toward the rear obliquely upward rises along the wall W, flows in a direction away from the wall W along the ceiling, descends near the wall on the opposite side of the room, and moves along the floor F. Circulates in the room by flowing in the direction of the wall W.

Next, the second ventilation path 4 will be described. An air filter 40, a second blower 14, an ion generator 12, an ion sensor 17, and the like are disposed in the second ventilation path 4. The second ventilation path 4 is divided by the second blower 14 into a lower suction chamber 4a and an upper blowout chamber 4b. The front part 61 of the housing 6 has a front panel 611 and a front cover 612, and the suction port 41 is provided in the front cover 612. The front panel 611 covers the upper side of the suction port 41 and both left and right sides from the front side. The suction chamber 4 a communicates with the outside through the suction port 41. The air outlet 42 opens at a boundary portion between the front panel 611 and the top cover 62 of the housing 6, and the air outlet chamber 4 b communicates with the outside via the air outlet 42, and the air outlet 4 a The chambers 4b communicate with each other via the second blower 14.

The air filter 40 is, for example, a rough lattice net, and is detachably disposed on the suction port 41. The air filter 40 collects and removes coarse dust contained in the air flowing into the suction chamber 4a.

The second blower 14 includes a fan motor (not shown) and a fan 142, and the fan motor drives the fan 142 to rotate about a horizontal axis. The fan 142 is a cross-flow fan having a cylindrical multi-blade impeller having a plurality of blades whose outer edge side is displaced in the rotation direction with respect to the rotation center. The fan 142 is arranged so that the direction of the rotation center is the left-right direction of the air cleaner 1. The fan motor is fixed inside the housing 6 by a support portion (not shown). The fan 142 is fixed to the output shaft of the fan motor and rotates by driving the fan motor. As the fan 142 rotates, the indoor air (specifically, the air below the front of the housing 6) passes through the suction port 41 as shown by the solid arrow in FIG. The air sucked into the air 4 flows into the blowout chamber 4b from the suction chamber 4a and blows out into the room through the blowout port 42. On the wall surface of the blowout chamber 4b, an ion generator 12 is disposed on the upstream side, and an ion sensor 17 is disposed on the downstream side.

The ion generator 12 is fixed to the wall of the blowout chamber 4b, and has a needle-like discharge electrode and an induction electrode arranged opposite to the discharge electrode. The discharge electrode to which a high voltage is applied causes a corona discharge to be positive or negative. Generate ions. The discharge electrode of the ion generator 12 is exposed to the blowout chamber 4b, and the generated positive and negative ions float in the air flowing through the blowout chamber 4b and are sent out together with the air from the blowout port 42. Positive and negative ions released into the room together with the air blown out through the air outlet 42 kill or inactivate fungi, viruses, allergens, etc., and cause substances that cause malodors (for example, organic compounds such as acetaldehyde). Decompose.

The ion sensor 17 detects positive and negative ions flowing through the blowing chamber 4b. This detection result shows the number of positive and negative ions flowing through the blowing chamber 4b, and thus the number of positive and negative ions generated by the ion generator 12. When the amount of positive and negative ions generated by the ion generator 12 is below a predetermined amount, it can be seen that the ion generator 12 is fouled or deteriorated.

In the suction chamber 4a, the air flows from the front lower side to the rear upper side, and in the blowing chamber 4b, the air flows in the front upper side. In addition, the air direction restriction plate 43 is disposed at the air outlet 42 in order to restrict the direction in which the air flows, and the second ventilation path 4 is provided in front of the air so that the blown air can easily reach the central portion of the room. Air blows diagonally upward.

The direction of air blown out from the second ventilation path 4 is different from the direction of air blown out from the first ventilation path 3. That is, air is blown out from the first ventilation path 3 in the diagonally upward rear direction, and air is blown out from the second ventilation path 4 diagonally upward in the front, and the first ventilation path 3 and the second ventilation path. The air is blown out obliquely upward from 4 and in a direction opposite to each other in plan view.

Next, attachment and removal of the air purification unit 11 to the air purification chamber 35 will be described. When the air purifying unit 11 is used for a long time, dust and odor adhere to it and the dirt progresses, the dust and odor adsorbing power decreases, and it becomes a resistance to suck in air, and the purification efficiency of the air purifier, Reduce power efficiency. In order to clean or replace the air purification unit 11 that has become dirty, it is necessary to remove it from the air purification chamber 35 and attach it to the air purification chamber 35 after cleaning or replacement.
