Description

  The present invention relates to an air cleaner that supplies purified air and ions into a room, and a method of using the air cleaner.

  In the air cleaner, a ventilation path extending from a lower suction port to an upper outlet is formed inside, and a purification filter and a blower are arranged in the ventilation path. In such an air cleaner, when the air in the room sucked from the suction port passes through the purification filter in accordance with the operation of the blower, harmful substances contained in the air are collected, adsorbed and decomposed by the purification filter. The air that has been removed and purified, for example, is blown into the room through the outlet.

  When air is blown out from the air purifier, in order to improve the supply state of the purified air to the room, the upper part of the ventilation path leading to the upper outlet is inclined rearward, and the air is blown into the room obliquely rearward and upward. A model has been developed in which air hits the indoor wall located on the back of the air purifier and circulates so that it passes through the ceiling, hits the opposite wall, and returns to the floor (see Patent Document 1).

  On the other hand, the air hitting the lower part of the front cover 16 enters the concave groove 16c and flows along the lower inclined surface 16b, further flows between the bottom surface and the floor surface F, reaches the back surface side, and enters the suction port 2a. Sucked. The air sucked into the suction port 2a passes through the deodorizing filter 7a, the dust collection filter 7b, and the humidification filter unit 3 to be purified and humidified (or not humidified), and is blown out from the air outlet 15 on the upper surface. Hereinafter, such air circulation is repeated.

  Next, the usage pattern different from the above of an air cleaner is demonstrated. FIG. 12 is a diagram for explaining how to use the air cleaner. In this mode of use, the air cleaner is not on the wall, but on the floor F near the boundary between the living room and dining kitchen of the LDK type room, with the air outlet 17 and the suction port 18 facing the dining kitchen side, Panel 2 is installed facing the living room. Odors and bacteria are more likely to occur in the dining kitchen than in the living room, so by releasing ions intensively toward the dining kitchen, the generation of odors and bacteria can be suppressed. Purified air can be supplied. As a result, the functions of two air purifiers, that is, an air purifier for supplying purified air and an air purifier for supplying ions can be realized by one air purifier.

  In the above-described embodiment, the air purifier including the deodorizing filter 7a, the dust collection filter 7b, and the humidifying filter unit 3 in the air purification ventilation path has been described. However, the present invention is not limited thereto. For example, an air cleaner that includes the deodorizing filter 7a and the dust collection filter 7b and does not include the humidifying filter unit 3 may be used.

  In the above-described embodiment, the front panel 23 is fixed to the housing 1, but the front panel may be supported by the housing 1 so as to be vertically slidable or swingable back and forth with the upper side as a fulcrum. 13 and 14 are a side view and a partial cross-sectional view schematically showing another embodiment of the air cleaner according to the present invention. 14B shows a cross section taken along line BB of A. FIG.

  FIG. 13 shows an example of a front panel 23 </ b> A that can swing back and forth. An upper end 23 </ b> A <b> 1 of the front panel 23 </ b> A is fitted on a shaft 23 </ b> A <b> 2 fixed to the housing 1 and is rotatably supported. When the front panel 23A is swung to the front side with the upper end 23A1 as a fulcrum, the gap between the front panel 23A and the suction port 18 increases, so that the ventilation resistance of the air sucked into the suction port 18 decreases, and the front panel 23A Is swung to the rear side, the gap between the front panel 23A and the suction port 18 is reduced, so that the ventilation resistance of the air sucked into the suction port 18 is increased. FIG. 14 shows an example of a front panel 23B that can slide up and down. An upper portion 23B1 of the front panel 23B is externally fitted to a rail 23B2 fixed to the housing 1 and is supported so as to be slidable up and down. When the front panel 23B is slid upward, the lower portion of the suction port 18 is exposed, and the ventilation resistance of the air sucked into the suction port 18 is reduced. When the front panel 23B is slid downward, the suction port 18 The ventilation resistance of air sucked into the suction port 18 is increased without exposing the lower part of the air.

  In the above-described embodiment, the wheel 9 is attached to the bottom surface of the housing 1, but a leg may be attached instead of the wheel.

  In the present invention, the generated ions include charged fine particle water. At this time, the ion generator includes an electrostatic atomizer, and charged fine particle water containing a radical component is generated by the electrostatic atomizer. That is, condensation water is generated on the surface of the discharge electrode by cooling the discharge electrode provided in the electrostatic atomizer by the Peltier element. Next, when a negative high voltage is applied to the discharge electrode, charged fine particle water is generated from the dew condensation water. In addition, negative ions released into the air together with the charged fine particle water are also generated from the discharge electrode.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is intended to include all modifications within the scope of the claims and the scope equivalent to the scope of the claims.
