Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a filter unit, and more particularly to a filter unit for an air conditioner.

[0002]

2. Description of the Related Art An air conditioner is a device in which air is taken in from an air intake, conditioned in the device, and then blown out from an outlet. The accumulation of dust and the like contained in the air taken in from the air intake port inside the air conditioner may lower the air conditioning function. In order to avoid such functional deterioration, an air filtration filter is often installed in an air intake port or a ventilation path of an air conditioner.

[0003]

The air conditioner is provided with an air filtration filter, so that accumulation of dust and the like in the device can be suppressed. However, on the other hand, dust and the like removed from the air accumulate in the air filtration filter.
For this reason, in an air filtration filter used for a long period of time, the air filtration filter is clogged with dust, so that the amount of air flow decreases. As a result, the amount of air that can be subjected to conditioning processing decreases due to a decrease in the amount of air taken in by the air conditioner, and as a result, processing efficiency of the air conditioner decreases. In such a case, by replacing the air filtration filter,
The processing efficiency of the air conditioner can be restored.

However, the conventional air filtration filter of the air conditioner has the following problems. First, it was necessary to ask the trader to replace the air filtration filter, or the user could replace the air filtration filter, but the work was difficult. Furthermore, since it is necessary to reserve a spare air filtration filter in case of replacement, it is necessary to provide a storage location for a spare air filtration filter.

[0005] The air filtration filter includes a filter medium for filtering air and a filter medium support for supporting the filter medium. The filter medium support is often made of a material (metal, resin, etc.) different from the filter medium. For this reason,
In many cases, the replaced air filtration filter must be disassembled and separated into a filter medium and a filter medium support, and disposed of.
Furthermore, the air filtration filter after replacement has been troublesome to disassemble and separate because the dust and the like have accumulated in the filter medium.

[0006] Further, the price of the air filtration filter is usually higher than the price of the filter medium alone because the price of the filter medium support part is included. It is an object of the present invention to provide a filter unit of an air conditioner that can easily restore the processing efficiency of the air conditioner and that requires less cost for restoration.

[0007]

According to a first aspect of the present invention, there is provided a filter unit for an air conditioner, the filter unit being attached so as to cover an air intake of the air conditioner. A long filter roll, a supporting portion for supporting the roll, and a holding frame. The filter frame body includes a roll, a support portion, and a holding frame, and further has a ventilation path for ventilating the air intake port of the air conditioner via the expanded filter. It is. The filter roll is formed by winding a long filter having a drawn-out length for a plurality of times into a roll shape. The holding frame holds the filter drawn out from the roll by a predetermined drawing length in the ventilation path of the filter frame in an expanded state.

[0008] The filter for air filtration is in the form of a roll. For this reason, when dust accumulates on the used filter, the filter can be replaced by pulling out an unused clean filter from the roll. This replacement work does not require installation or removal work,
This can be easily performed by the user.

[0009] The holding frame is for holding the filter, and replaces the conventional filter medium supporting portion.
Since the holding frame can fix the filter a plurality of times, there is no need to dispose of the holding frame after use as in the conventional filter medium support portion. Therefore, the amount of waste generated when restoring the processing efficiency of the air conditioner can be suppressed. In addition, since the holding frame for holding the filter and the filter corresponding to the conventional filter medium are not integrated and are separate members, there is no need for a sorting operation when disposing of the used filter.

[0010] Here, the drawn-out length refers to the length of the filter required to cover the ventilation path of the filter frame. The filter unit of the air conditioner according to claim 2 is the filter unit of the air conditioner according to claim 1, wherein the filter frame has an outlet for taking out and discarding the filter after use.

When the filter is replaced, the filter can be pulled out through the outlet. Therefore, the replacement work of the filter becomes easy. The filter unit of the air conditioner according to claim 3 is the filter unit of the air conditioner according to claim 1 or 2, wherein the filter is:
A perforation is provided for each predetermined drawing length.

Since the filter is provided with perforations, the filter can be easily cut off when the user performs a filter replacement operation.
