Description

TECHNICAL FIELD The present invention relates to improvement of usability of a filter member of an air purifier.

2. Description of the Related Art Conventionally, in the filter member of this type of air purifier,
As a maintenance at the time of use, regular cleaning and replacement of the filter member have been required.

At that time, since the filter member adsorbs dust or the like, it is generally highly contaminated, and when taking out the filter member, it was important to be able to work hygienically without soiling the fingers.

Therefore, the filter member is surrounded by a frame so as to be integrally molded, or a separate case for the filter member is prepared so that the filter member can be cleaned or replaced without directly touching the dirty filter member with fingers.

The problem to be solved by the invention is, however, due to the above-mentioned configuration, since additional components are added to the filter member as an original air purifier such as a frame and a case, production costs and component replacement costs are extra. However, when setting the filter member on the frame or case, the outer peripheral part of the filter member is partially covered by the edge of the frame or case, reducing the effective surface area of the filter member and reducing the dust collection performance of the air purifier. It had a serious problem of basically lowering it.

Further, it is difficult to know when to replace the filter member, and the filter member is usually replaced at the discretion of the user, so that the filter member cannot be used efficiently.

Means for Solving the Problems In the present invention, in order to solve the above-mentioned problems, an openable and closable front panel having an intake port is provided on the front surface of the body, and a filter member made of non-woven fabric is attached to and detached from the front body. The filter member has a tongue portion which is integrally formed with the member main body and protrudes outward from the outer edge portion of the member main body. A display portion colored in the same color is provided, and the tongue portion is provided with a rib that avoids the air passage in the body and that separates the air passage from the tongue portion inside the front panel.

Effect In the present invention, the filter member is formed integrally with the tongue portion and is positioned so as to avoid the air passage, so that the filter member covers a part of the surface by the frame or the edge of the case to reduce the effective surface area. Moreover, since the tongue does not pass through the dirty air, the filter member can be handled by holding the tongue without soiling the fingers.

Furthermore, when it is time to replace the filter member, the tongue that serves as a replacement time indicator can inform the user of that fact, and since dirty air does not pass through the tongue, the tongue does not become dirty. Can be exchanged by holding.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings.

1 and 2, a filter member 2 and a motor fan 3 are provided in a ventilation passage 6 connecting an intake port 4 to an exhaust port 5 in a body 1 of an air purifier. Reference numeral 2 denotes a tongue portion 8 formed integrally with the member main body 7 and protruding outward from an outer edge portion of the member main body 7.
The tongue portion 8 is formed so as to be positioned so as to avoid the air passage 6. Reference numeral 9 denotes a front panel removably attached to the front surface of the body 1, and the tongue portion 8 is formed so as to be covered by the front panel 9 so as to avoid the air passage 6.

Further, as shown in FIG. 3, the filter member 2 is provided on the tongue portion 8.
The display portion 10 colored in the same color as the color at the time of replacement is provided as a guide for replacement of the filter member 2.

In the above structure, the contaminated air is sucked from the intake port 4 by the operation of the motor fan 3, is filtered and purified by the filter member 2, and passes through the motor fan 3 and the exhaust port 5.
Is discharged to the outside of the body 1. That is, the contaminated air is filtered and purified while passing through the ventilation path 6, and the dust-containing component contained in the contaminated air is adsorbed to the member main body 7 of the filter member 2, but the tongue portion 8 is ventilated. Since it is formed so as to avoid the path 6, it will escape pollution.

Therefore, when the filter member 2 is regularly cleaned or replaced for maintenance during use, the front panel 9 is removed and the tongue 8 is held to supply the filter member 2 for cleaning or replacement, so that work can be performed without soiling the fingers. it can. Moreover, since no special frame or case is required, the filter member 2
As a result, the effective surface area is not impaired and no extra parts are required, which is advantageous in terms of cost.

Further, by providing the tongue portion 8 with the display portion colored in the same color as the color of the time when the filter member 2 is replaced, the user can be notified of the time when the filter member 2 is replaced accurately.

Advantageous Effect of the Invention As described above, according to the present invention, the filter member can be maintained without polluting the fingers without extra cost, and the filter member can be effectively used in terms of performance. Furthermore, since dirt does not attach to the surface of the tongue, the tongue is provided on the display section colored in the same color as the color of the time when the filter member should be replaced, so that the user can be accurately notified of the time when the filter member should be replaced. It is possible to provide an air purifier that is very useful in terms of maintenance.
