Abstract

(57) [Summary] [Purpose] Development of an air purifier that enables miniaturization. [Constitution] A cleaning filter whose side surface is formed in an inverted U shape is installed inside a case. [Effect] Since the amount of air passing through the cleaning filter is increased, it is possible to use a small sirocco fan and a motor, and thereby the overall shape of the air cleaner can be downsized.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an air purifier to be installed and used on a rear parcel shelf of an automobile, for example.

[0002]

[Prior art]

 A conventional air purifier of this type has a structure as shown in FIG. This conventional example will be described below.

An air purifier 1 is installed on a rear parcel shelf of an automobile. The air purifier 1 is provided in a case 4 having an air suction port 2 and an air discharge port 3, and in the case 4. Further, it has a flat plate-like cleaning filter 5 arranged so as to close the air intake port 2 and a sirocco fan 7 driven by a motor 6, and by driving the motor 6, the sirocco fan 7 is The air that is rotated and sucked from the air suction port 2 by the rotation force is deodorized and deodorized by passing through the inside of the cleaning filter 5, and is then cleaned by the driving force of the sirocco fan 7. The cleaning air is discharged.

[0004]

[Problems to be solved by the device]

 However, the shape of the cleaning filter 5 of the air cleaner thus configured is a flat plate shape corresponding to the air suction port 2, and the ventilation area of the cleaning filter 5 is relatively small. If an attempt is made to improve the dust collecting and deodorizing ability of the air purifier, the pressure loss of the cleaning filter 5 increases, and in order to compensate for this loss, it is necessary to enlarge the sirocco fan 7 and the motor 6, and the air purifier. There is a problem that it is a factor that hinders the miniaturization of the.

[0005]

[Means for Solving the Problems]

 The present invention has been made by paying attention to this conventional problem, and is equipped with a clean filter having a large ventilation area and excellent dust collecting and deodorizing ability, and pressure loss per unit area of the clean filter. Is to provide an air purifier that enables miniaturization of a sirocco fan and its motor even if it is the same as the conventional example, and eventually miniaturizes the overall shape of the air purifier.

【Example】

 The present invention will be described in detail below with reference to the embodiment shown in FIGS. 2 and 3. The same parts of the structure of this embodiment and the structure described in the conventional example are designated by the reference numerals used in the conventional example. Then, the structural description of the same structural part is omitted.

That is, the feature of the present embodiment is the shape of the cleaning filter 8 that removes dust and deodorizes air.

The shape of the cleaning filter 8 of this embodiment is a dome shape having an inverted U-shaped side surface, and the cleaning filter 8 is arranged on the suction port 2 and the intake side of the sirocco fan 7. is there.

Although the cleaning filter 8 of this embodiment is formed in an inverted U-shape as a single unit, the invention is not limited to this. For example, a single or a plurality of flat plates or curved plates are combined to form an inverted U-shape. It may be combined with the cleaning filter 8 of FIG.

When the motor 6 of the air purifier in which such an inverted U-shaped cleaning filter 8 is installed is driven, the sirocco fan 7 is rotated, whereby dirty air outside the air purifier is sucked through the suction port 2. After that, it is sucked into the case 4. The air sucked into the case 4 through the suction port 2 permeates the surface of the cleaning filter 8 and passes through the cleaning filter 8 to collect and deodorize the contaminated air to become purified air. It is discharged from the discharge port 3 to the outside of the purifier.

As described above, in this embodiment, the cleaning filter 8 is formed in an inverted U shape so that the entire surface area of the cleaning filter 8 is expanded. Even if the pressure loss per unit area of is the same as that of the conventional filter, the throughput (cleaning capacity) of the air passing through the entire surface of the cleaning filter 8 is increased, which allows, for example, air cleaning. When the capacity is the same as that of the conventional example, the sirocco fan 7 and the motor 6 can be downsized, and in turn, the overall shape of the air purifier can be downsized.

FIG. 4 shows an air purifier equipped with a cleaning filter 8 of another embodiment. This cleaning filter 8 is a sheet-shaped filter that is pleated, and the pleated-shaped filter is inverted U-shaped. It is formed in a letter shape. Therefore, according to the cleaning filter 8 of this embodiment, the surface area of the cleaning filter 8 can be further expanded as compared with the surface area of the cleaning filter 8 of the above embodiment, and the air cleaning capacity can be further enhanced.

[0013]

[Effect of device]

 As described above, according to the present invention, the air purifier case 4 is provided with the air discharge port 3 and one or a plurality of air suction ports 2, and the side-reverse U-shaped cleaning filter 8 corresponding to these air suction ports 2 is provided. Is housed in the case 4, and is further provided with a sirocco fan 9 that allows the air sucked from the suction port 2 to pass through the cleaning filter 8 and be discharged from the air discharge port 3. Therefore, according to this, the shape of the cleaning filter 8 is made into an inverted U shape, and the entire surface area of the cleaning filter 8 is expanded. Therefore, the pressure loss per unit area of the cleaning filter 8 is Even if the filter is the same as the example filter, the throughput (cleaning capacity) of the air passing through the entire surface of the cleaning filter 8 is increased, so that, for example, the air cleaning capacity is the same as the conventional example. When It is possible to reduce the size of the sirocco fan 7 and the motor 6, is attracted Ru effect is obtained that it becomes possible to miniaturize the entire shape of the air purifier.
