Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an air cleaner that purifies air by passing an air flow formed by a blower through a filter.

[Conventional technology]

An air purifier that uses a filter to purify the air is, in a narrow sense, a device that removes floating dust and harmful gas components from indoor air, but in a broader sense, it also includes air conditioners that use a filter to remove air pollution. It is something that In any case, a filter that cleans the air only to become more contaminated needs to be cleaned or replaced. In conventional air purifiers, for example, as seen in Japanese Patent Application Laid-open No. 59-13440, an opening is formed in a part of the front intake grille, and a part of the filter, which is the main body of the air purification function, is visible through the opening. It is configured so that it can be done.

A conventional air purifier configured as described above is
The degree of dirt on the filter can be visually observed through the opening of the suction grill, and it is possible to determine whether the filter needs to be cleaned or replaced.

[Problem that the invention attempts to solve]

In the conventional air cleaner as described above, even if the degree of dirt on the filter can be visually observed through the opening, it is not possible to know the degree of dirt on the filter. That is,
The entire surface of the filter that can be seen through the opening is dirty to the same extent, so unless it is extremely dirty, it is impossible to know the degree of dirt because there is nothing to compare it to.

This idea was made to solve this problem, and by purifying the air, you can easily know the degree of dirt on the filter, and you can clean and replace the filter at the appropriate time. The purpose is to obtain a purifier.

[Means for solving problems]

In the air purifier according to this invention, a comparison capsule consisting of a filter that purifies the air and a portion that is dirty and a portion that is not is removably attached to a part of the suction grill provided in front of the filter.

[Effect of means to solve problems]

In this design, the comparison capsule shows areas that are contaminated by air pollution and areas that are not contaminated, and the contaminated areas are placed under the same conditions as the filter, and correspond to the degree of contamination caused by the filter's air purification. Therefore, the current degree of contamination of the filter can be determined based on the uncontaminated portion.

〔Example〕

The air cleaner as an embodiment of the present invention shown in FIG. 1 has a box-shaped main body casing 1 provided with an orifice 2 directed in the front-rear direction, and a blower 3 for forming an air flow in the front-rear direction installed in the center of the orifice 2. , and a filter 4 is mounted on the front surface of the main body casing 1 by pressing it down with a suction grill 5 on the outside.
The back side of the main body casing 1 is closed as a differential user 6, and air outlets 7 are opened on the top, bottom, right and left sides of the back side. A filter 4 attached to the suction port on the front surface of the main body casing 1 purifies the air flow generated by the blower 3, and is the main body of the air purifying function. A comparison capsule 8 is removably fitted into a part of the suction grille 5, which is configured to be removably attached to the front surface of the main body casing 1 that presses the outside of the filter 4, so that it can be seen from the outside. There is. The comparison capsule 8 is a cylindrical (or rectangular) transparent container 9 filled with a filter material 10 of the same type as the filter 4, and approximately half of the transparent container 9 has small holes 11 or slits to allow ventilation. is formed. This comparison capsule 8
The structure on the side of the suction grille 5 into which the comparison capsule 8 is fitted is a recess 12 formed in the lateral direction and allowing ventilation into which the comparison capsule 8 can be fitted. That is, the recess 12 has a hole 13 through which the air flow generated by the operation of the blower 3 passes.
is located on the bottom side. A color sample 14 is applied to the end of the contrasting capsule 8 on the side where the small hole 11 is located, showing in color tone the stain of the filter 4 when the filter 4 needs to be replaced.

However, when air purification operation is performed, indoor air is sucked in from the intake grille 5 through the filter 4,
The air is purified by the filter 4 and then blown into the room from the air outlet 7. The filter 4 becomes dirty as the air is purified, so it needs to be cleaned or replaced. The dirt on the filter 4 will appear in approximately half of the comparison capsule 8 where the small holes 11 are located, and the dirt will not appear in the other half of the comparison capsule 8. It is possible to know the degree of progress of the stain at the present time. That is, since the air flow from the blower 3 passes through approximately half of the filter material 10 packed in the comparison capsule 8, the filter material 10 becomes dirty to approximately the same degree as the filter 4. By comparing the appearance (mainly color tone) of approximately half of the filter material 10 that is not soiled with the appearance of approximately half of the filter material 10 that is soiled, the degree of soiling of the filter 4 can be known with sufficient certainty. cleaning·
This is a guide to know when replacement is required. If the color sample 14 matches the color tone of approximately half of the dirty filter material 10, the filter 4 can be replaced with a new one.

[Effect of idea]

As is clear from the above description of the embodiments, the air purifier of the present invention has a contrasting capsule filled with the same type of filter material as the filter in a see-through container, in a part of the suction grill provided in front of the filter. Since it is removably attached and has a structure that allows ventilation to about half of the comparison capsule, it is possible to expose the dirt on the filter that gets dirty along with the purification effect to about half of the comparison capsule. By comparing it with the other non-contaminated half, the degree of contamination of the filter can be easily determined. Therefore, the arbitrariness of cleaning and replacing the filter can be eliminated, and the filter can be properly cleaned and replaced.
