The main part frame body 2 and the front part frame body 3 are joined by the butt joint part 16, and form the outline of an air cleaner. A blower port 12 is located on the upper surface of the main frame 2, and clean air purified from the blower port 12 is blown into the room. A water supply tank 13 is detachably attached to one side of the main frame 2.

  In FIG. 2, a filter unit 5, a humidifying filter 6, and a blower 7 are provided inside the air purifier main body 1 facing the inner wall surface of the front panel 4. The filter unit 5 is located on the front frame 3 side, and the humidifying filter 6 is located below the blower 7. The blower 7 is located on the main frame 2 side, and includes a blower 7a and a turbo fan 7b.

  The main frame 2 has a fan casing 8 inside, and a blower 7 a is attached in the fan casing 8. The suction plate 9 that guides the suction flow to the turbo fan 7 b is formed so as to surround the turbo fan 7 b together with the fan casing 8.

  In the main frame 2, the filter unit 5 is installed so as to fit in the space on the front side of the front frame 3. In the upper part of the back space, there are provided a shutter plate 21 having an opening gap and a shutter 22 for opening and closing the opening gap so that the flow path can be opened and closed. A humidification channel in which the humidification filter 6 is installed is formed below the shutter 22.

  The shutter 22 is provided with a guide pin (not shown) and is attached to the front frame 3 so as to be slidable in the vertical direction. In addition, a horizontally long oval cutout hole (not shown) is provided on the upper portion of the shutter 22.

  At the top of the blower 7, a motor 26 for operating the shutter having a cam plate (not shown) corresponding to an oval cutout hole (not shown) for operating the shutter 22 is attached. Yes. The electric motor 26 is protected from dust by surrounding the front surface with a cover (not shown) having an output shaft hole and the suction plate 9 on the rear surface.

  The control device 10 is provided on the upper front side of the air cleaner body 1, and the operation of the air cleaner is controlled by the control device 10, and the operation status is displayed on a display device (not shown). ing.

  Air is sucked from the surrounding air inlet 11 of the front panel 4 and circulates in the filter unit 5 so that dust is removed, and component substances such as odor and formaldehyde contained in the air are removed, and the air outlet 12 is discharged.

  The humidifying filter 6 humidifies moisture in the air from which component substances such as dust, smell and formaldehyde are removed. And the air suck | inhaled by the air blower 7 turns into the clean air from the ventilation port 12, and is ventilated outside the air cleaner.

  The cartridge water supply tank 13 shown in FIG. 1 is for replenishing water to the reservoir water tank 14 in which moisture is immersed in the humidifying filter 6. The cartridge water supply tank 13 is removable in the side surface direction of the air cleaner body 1.

  Although not shown, the cap provided at the bottom of the cartridge water supply tank 13 has a valve body that closes the outlet of water. When the cartridge water supply tank 13 is removed from the air purifier main body 1, the valve body closes the outlet, and when the cartridge water supply tank 14 is mounted, the valve body opens the outlet.

  By the way, the shutter attached to the air cleaner main body 1 shown in FIGS. 1 and 2 has a structure in which the opening is opened and closed in a fixed position. In other words, when the shutter opening is “open”, the air is in the air cleanliness mode that flows through both the filter unit and the humidifying filter, and when it is “closed”, the air is in the humidification mode that is mainly flowing in the direction of the humidifying filter.

  However, although it is in the humidifying mode, air passes through the humidifying filter after passing through the filter unit and then passes through the humidifying filter, so that the airflow resistance is large and is not suitable for improving the humidifying ability.

  Accordingly, the inventors of the present invention have studied various structures through which air passes through the humidifying filter, and as a result, obtained the following examples.

FIG. 3 is a cross-sectional view of an air cleaner provided with an embodiment of the present invention. (In addition, since the same number as FIG. 2 is the same thing, the description is abbreviate | omitted).
In FIG. 3, although it demonstrated as the filter unit 5 in FIG. 2, in FIG. 3, the dust collection filter 5a and the deodorizing filter 5b are installed in parallel. The humidifying filter 6 is attached directly below the deodorizing filter 5b and on the same plane as the moving direction of the shutter that moves up and down (coaxial with the axis of the deodorizing filter).

  The shutter 22 described in FIG. 2 has a structure that opens and closes the opening at a fixed position. However, the shutter 22 according to the present embodiment moves up and down to close the deodorizing filter 5b and the humidifying filter 6. (Details will be described later).

The operation of the conventional shutter and the operation of the shutter of the present invention will be compared and described with reference to FIG.
In FIG. 4, in the conventional air cleaner body 1, when the humidification mode operation is performed with the opening of the shutter 22 closed, the air passes through the dust collection filter 5 a and the deodorization filter 5 b as indicated by the arrow, and then the humidification filter 6. Pass through. As can be seen from FIG. 4, since the shutter 22 only opens and closes the opening at a fixed position in front of the deodorizing filter 5b, air always passes through the humidifying filter 6 regardless of opening and closing.

  In contrast, in the present invention, in the air cleaning / deodorization mode, the shutter 22 moves downward to close the humidification filter 6, so that air flows around the deodorization filter 5b as indicated by an arrow, and a high deodorization effect can be obtained. it can. On the other hand, in the humidification mode, the shutter 22 rises and closes the deodorization filter 5b, so that air flows around the humidification filter 6 as indicated by an arrow. Therefore, a high humidification effect can be obtained.

Example 2 will be described with reference to FIGS.
FIG. 5 is a schematic configuration diagram of the second embodiment.
FIG. 6 is a diagram for explaining the outline using the shutter as an operating means.

  In FIG. 5, the shutter 22 is supported inside the shutter frame 22a. The shutter 22 moves up and down along a rail (not shown) attached to the inner surface of the vertical frame of the shutter frame 22a. Since FIG. 5 shows a state where the deodorizing filter 5b is moved to a position where the deodorizing filter 5b is closed, air flows in the direction of the humidifying filter 6 as indicated by an arrow.

Specific moving means of the shutter 22 will be described with reference to FIG.
In FIG. 6, the shutter 22 is suspended by a wire 22d. The wire 22d is wound around the pulley 22c. Since the pulley 22c is connected to the motor 22b via the gear 22e, the pulley 22c moves up and down by forward and reverse rotation of the motor 22b.

  In FIG. 6, since the shutter 22 is stopped at the position where the humidifying filter 6 is closed, the air purification / deodorization mode state is shown.

  Thus, according to the present embodiment, the shutter 22 can be accurately moved up and down with a simple structure.

FIG. 7 is a schematic configuration diagram of the third embodiment.
In the embodiment shown in FIG. 7, the deodorizing filter 5b is closed with the shutter 22 divided into two. When the humidifying filter 6 is closed, the humidifying filter is closed by moving the shutter 22 divided in two as shown in the dotted line in a stacked state.

  In this embodiment, the shutter 22 is divided into two parts. However, it is not always necessary to divide into two parts, and the number of divisions may be increased as long as it can be stored in the housing.

  Thus, according to the present embodiment, it is possible to switch between the air purification / deodorization mode and the humidification mode with a simple structure.

FIG. 8 is a schematic configuration diagram of the fourth embodiment.
In the embodiment shown in FIG. 8, the deodorizing filter 5b extends to the humidifying filter 6 and is constituted by a plurality of rotatable armor doors.
In FIG. 8, the humidifying mode is set by tilting the armor door on the humidifying filter 6 side in the horizontal direction and bringing the armor door on the deodorizing filter 5b side into a vertical state. Of course, as shown by the dotted line, the armor door on the deodorizing filter 5b side is horizontal and the humidifying filter 6 side is in the vertical state, so that the air cleaning / deodorizing mode can be set.

  Thus, according to the present embodiment, it is possible to switch between the air purification / deodorization mode and the humidification mode with a simple structure.

FIG. 9 is a schematic configuration diagram of the fifth embodiment.
In FIG. 9, the embodiment so far has been described on the assumption that the deodorizing filter 5 b and the humidifying filter 6 are in a vertical positional relationship. However, in this embodiment, the deodorizing filter 5 b and the humidifying filter 6 are arranged in the horizontal direction. It is a side-by-side configuration.

  In this embodiment, as in FIG. 5, the shutter 22 is housed in a shutter frame 22a, and the shutter 22 moves in the left-right direction within the frame. In FIG. 9, since the deodorizing filter 5b is closed by the shutter 22, the air is in a humidifying mode in which the air flows on the humidifying filter 6 side as indicated by an arrow.

  As described above, according to the present invention, the deodorizing filter and the humidifying filter are arranged coaxially in the vertical direction from the main body floor surface, and the flow path can be switched by the shutter function, so that the operation specialized for deodorization and humidification are specialized. Driving is possible. Moreover, ventilation resistance can be reduced and a humidification capability can be improved rather than before. In addition, the deodorizing filter can be attached to and detached from the main body as a unit member, and the unit member of the deodorizing filter is configured by a plurality of piece parts, and it is possible to insert different types of deodorizing materials. It becomes possible and can be made into a series.

  Furthermore, as a function different from the deodorizing function, if a material that reversely releases odor is installed, or a filter that collects and suppresses fine dust is provided, the functions of the main body can be varied depending on the application. It is possible to provide an air cleaner having effects such as being able to increase.

  Further, since the deodorizing filter and the humidifying filter are arranged coaxially in the vertical direction from the main body floor surface and the flow path can be switched by the shutter function, an operation specialized for deodorization and an operation specialized for humidification are possible. Moreover, ventilation resistance can be reduced and a humidification capability can be improved rather than before.

  In addition, the deodorizing filter can be attached to and detached from the main body as a unit member, and the unit member of the deodorizing filter is configured by a plurality of piece parts, and it is possible to insert different types of deodorizing materials. It becomes possible and can be made into a series.

  Furthermore, as a function different from the deodorization function, if you install a material that reversely releases odors or provide a filter that collects and suppresses dust other than fine dust, you can change the function of the main body according to the application. It is possible to provide an air cleaner having effects such as being able to increase.
