BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air cleaner for removing dirt, suspended dust, house dust, and deodorizing indoor air during smoking and the like.

0002

[Prior Art] The basic components of an air purifier are a blower that circulates indoor air, purification means, and operation control means.
For example, as shown in Japanese Patent Application Laid-Open No. 59-217429,
The motor, fan, and purification means were added in the thickness direction. In addition, when replacing the filter, in order to enable both tabletop and wall-mounted use in the conventional example, the idea of installing the filter in the opposite direction when wall-mounted is mentioned. The idea was to either remove the front cover and replace it, or pull out the filter frame that houses the filter from the side of the main body. Considering that it can be pulled out laterally, it is presumed that the method of stacking the fan in the thickness direction has the advantage of being easier to move laterally. However, the aim is to make the product thinner, to obtain air that spreads across the width of the main body, which is difficult to achieve with conventional blower systems, and to obtain high purification performance through the gentle action of air on the human body. has arisen. It is necessary to consider improved filter structures with excellent purification performance and convenient filter replacement for users.

[Problems to be Solved by the Invention] In the present invention, firstly, fans having characteristics as centrifugal fans are connected in the horizontal direction to form a blower having wide air blowing characteristics. to obtain. It has sufficient pressure characteristics and can sufficiently cope with the ventilation resistance of the purification means. Second, a purifying means such as a wide filter should be arranged in parallel with the air blowing means and oriented toward the wide side, and the removal direction should be toward the front of the main body. Place it at an angle. Thirdly, the purifying means such as a filter is divided into a plurality of parts and connected in the horizontal direction to correspond to the width of the blower. Fourth, the filter has a large surface area of the fiber layer to improve purification performance and durability, but it is folded into pleats to make the filter smaller. This pleat direction arranges the pleat lines in the horizontal direction, making it possible to efficiently remove material during pleat production, reducing costs by reducing the number of pleats, and increasing strength in the transverse direction. The purpose is to strengthen the main body and strengthen it against vibrations that occur due to the wide width of the main body.

Fifth, the operation section is located at about 400 mm on the top surface of the front cover.
The center of the operation unit is placed at a 5° angle to improve visibility of the display, ease of operation, ease of assembly, and space-efficient layout of the electronic component device board.

[0005]

[Means for solving the problem] As mentioned above, various measures have been taken, but the major feature is that a wide filter, etc. is installed in parallel with the first and second wide air blowing means. The purifying means is arranged and the purifying means is arranged at an angle with respect to the main body so that the removal direction is toward the blowing means side.

[0006]

[Operation] By connecting a plurality of centrifugal fans, it looks like a cross-flow through fan, but it provides excellent blower characteristics in terms of air volume and static pressure.

[0007] A wide, soft wind similar to that of a penetrating fan can be obtained. Purifying means such as filters can be taken out in a cassette style from the front of the main body. It provides convenience to the user whether it is placed on a table (floor) or hung on a wall.

The stand 6 is removed, the main body is turned in the opposite direction, that is, the air outlet 8 is facing downward, and the mounting hole 10 of the rear cover 3 is hooked onto the protrusion of the wall bracket 11 to fix it. In FIG. 3, the circulation blower 12
is composed of a double shaft type motor 13, a double suction type centrifugal force fan 14, and a casing 15 communicating with the air outlet 8. In the air purifying means 16, a purifying filter 19 is housed in a filter frame 18 having a handle 17. In FIG. 4, the symbols used in the conventional drawings are used as they are. The filter frame 18 is tilted and supported by the inner cover 20. The filter cover 4 can be opened by an arm 21. The filter frame 18 is not stacked with the blower 12 in the thickness direction of the main body, and can be taken out diagonally toward the front of the main body by opening the filter cover 4.

The detailed shape of the component is shown in the exploded view of FIG. 5. For clarity of drawing illustration, stand 6, louver 9
etc. are omitted from illustration. The inner cover 20 functions as a partition wall forming a filter flow path and as an operation control means. It has a function as a support body for the control board 22 and the power supply board 23. The control board 22 is once fixed to the operation panel support 24, and
Each is fixed to the inner cover 23. The power supply board 23 is inserted into the power supply board support groove 25 of the inner cover 20 and fixed. 26 is a remote control receiving cover, 27 is a gas sensor board, and 28 is a human body sensor board, each of which is engaged and fixed to the operation panel support 24. As shown in FIG. 4, the center of the operation panel section 5 is approximately 45 mm from the front.
The control board 22 is also supported with its direction adjusted accordingly. This is achieved by shaping the mounting legs of the operation panel support 24 as shown in the figure. Figures 6 to 9 show how to replace the filter on a tabletop.

According to the present invention, as shown in FIG. 4, in the structure of the front cover 2, rear cover 2, and middle cover 20, the filter frame 18 is arranged parallel to the blower 12 and inclined. This makes it possible to create a thin structure instead of increasing the thickness of the main body 1. As shown in FIGS. 3 and 5, the blower 12 has double-suction type centrifugal fans 14 arranged on both sides of a motor 13. With this configuration, two filters 19 serving as purifying means are arranged side by side to form a filter frame 18.
By combining the configuration in which the wind is housed in the air, the effect of reducing the wind speed and making the wide circulation wind softer is produced. The filter 19 utilizes a pleated electret filter 31 as shown in FIG. 12, and the direction of the pleats is aligned with the width direction so that the pleat lines are arranged in the horizontal direction. As a result, even if the area is the same, the pleats are drawn in the longitudinal direction, so the filter sheet material before folding is selected and folded in the width direction, making material removal more efficient and reducing costs by reducing the number of folds. has been achieved. The structure is arranged so that the cross-sectional strength of the pleats acts in the direction of the width of the main body, which also has a reinforcing effect against vibrations generated during operation. By having a plurality of filters 19, it is easy to manufacture the filters, handle them, and replace and dispose them. As shown in Figures 6 to 11, the filter can be replaced by the operator by opening the filter cover 4 from the front of the main unit and taking out the filter frame 18, whether it is placed on a table (including when placed on the floor) or when mounted on a wall. This can be done in an easy-to-use manner. The approximately 45° arrangement of the operation panel section 5 makes the switches easy to operate and the display easy to see whether on a table or when mounted on a wall. For operation of a wireless remote controller (not shown), the remote control receiving cover 26 faces in an appropriate direction. Other gas sensor substrates 27 and human body sensor substrates 28 can also be appropriately arranged all at once. When assembling, remove the rear cover 3 and the middle cover 20.
, the operation panel support 24, and the front cover 2 can be assembled in this order. As can be seen from FIGS. 13, 14, and 4, the control board 22 and the power supply board 23 are configured to effectively utilize the space around the blower 12 and to be easily connected as electrical components in close proximity.
