Description

  The present invention relates to an air cleaner that takes in indoor air from a suction port provided in a lower part of a main body, cleans it with a filter, and blows out clean air into the room from a blowout port provided on a top surface of the main body.

  Conventionally, this type of air purifier is known to be capable of changing the intake ratio and the intake direction of a plurality of intake ports (see, for example, Patent Document 1).

  Hereinafter, the air cleaner will be described with reference to FIG.

As shown in the figure, the main body 101 includes a front air inlet 102 and a lower air inlet 103. The lower air inlet 103 opens near the lower end of the front cover 104 and has a larger opening area than the front air inlet 102. Thus, the contaminated air staying on the table top surface or the floor surface can be efficiently removed.

  In such a conventional air purifier, a suction port is provided at the lower part of the main body in order to suck in dust particles having a large particle size such as mite feces, dead bodies, and pollen that accumulate or float near the floor surface. Since the opening area of the suction port is small and the ventilation direction changes greatly between the suction port at the bottom of the main unit and the filter, suction force cannot be obtained sufficiently and it is not smoothly guided to the filter, so the particle size is large. However, there is a problem in that the dust cannot be sufficiently sucked and cleaned, and the air cleaning function cannot be sufficiently exerted on the dust near the floor surface.

  The present invention solves such a conventional problem, and it is possible to increase the suction air volume by increasing the opening area of the suction port at the lower part of the main body and to change the ventilation direction from the suction port at the lower part of the main body to the filter. An object of the present invention is to provide an air purifier capable of increasing the suction force by reducing the amount and capable of smoothly guiding and cleaning dust that has been sucked up and having a large particle diameter to a filter.

  In order to achieve the above object, the air cleaner of the present invention has a main body having an air inlet and an air outlet, an air passage provided in the main body so as to communicate the air inlet and the air outlet, A filter provided in the ventilation path for purifying the air taken in from the intake port; and a blowing means provided in the ventilation path for passing air through the filter, wherein the intake port is provided at least in a lower front portion of the main body.

An air outlet is provided on the top surface of the main body.

  Further, the other means is that the air blowing means is a centrifugal blower, and this centrifugal blower is disposed vertically downstream of the filter in the rear part of the main body, facing the discharge direction of the centrifugal blower, and the outlet of the top of the main body And an operation unit and a control unit are disposed on the top surface of the main body between the outlet and the filter.

  According to the present invention, a large amount of dust particles such as mite feces, carcasses, and pollen that are distributed in a low level indoor space such as near the floor surface are sufficiently sucked to increase the collection efficiency, and the amount of retained dust is large. It is possible to provide an air cleaner having an effect that the replacement frequency can be reduced by using the filter.

  In addition, by providing a lower intake port in the inclined part facing the floor at the lower front of the main unit, the opening area of the lower intake port can be increased, so that the intake volume is increased and dust with a large particle size drifting near the floor surface is increased. The filter can be guided linearly to increase the collection efficiency.

  In addition, since the vertically shaped side air inlet can relatively increase the opening area of the lower part of the main body, it can inhale a lot of dust with a large particle size distributed in the low-frequency space, and allergen substances such as tick feces Can be positively cleaned to improve the indoor environment.

  Further, by making the shape of the opening of the side intake port along the intake surface of the filter, the ventilation distance can be equalized and shortened, and contaminated air can be ventilated over the entire surface of the filter.

  Also, by providing a horizontally elongated second side air intake port in addition to the side air intake port, the opening area of the air intake port can be enlarged close to the floor surface, and a large amount of dust with a large particle size is sucked in. Thus, the allergen substance can be effectively purified over a wide range.

  In addition, there is no need to separate the front panel from the main unit and pull out the filter to the front as in the past, and the filter can be easily replaced from the top of the main unit. There is no need to provide a member in front of the air blower, and the air flow rate can be increased to improve the air cleaning capability.

  In addition, by integrally connecting the lid and the connecting means, the filter can be pulled out from the main body through the connecting means, and the filter can be exchanged with little contact with dust adhering to the filter. Can provide an easy-to-use air purifier.

  In addition, since the filter can be held by a frame that is integrally connected to the lid, even a low-rigidity filter can be prevented from being deformed and fully perform its purification function, making it easy to replace the filter and reducing the cost of consumable parts. The air cleaner can be made easy to use.
