DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner provided with a disposable filter at an intake port.

[0002]

2. Description of the Related Art In the present specification, an air conditioner is an air conditioner, a heating / cooling device, a cooler, an air purifier, a dust remover, a dehumidifier, etc. It shall include all devices for treating air and keeping its properties comfortable. The filter provided at the air inlet of the air conditioner is clogged with the operation of the air conditioner. This clogging causes a reduction in operating efficiency, so it must be kept clean at all times.However, even if the air purifier is used to clean the filter in a manner Filters are often disposable because it is difficult to completely remove dust and dirt. However, since such a disposable filter stretches a nonwoven fabric or the like at a predetermined position so as not to wrinkle, there is a problem that replacement work is troublesome and time-consuming. On the other hand, home air conditioners are often installed in high places, and since cleaning the filter takes a lot of time, cleaning is rarely performed as frequently as instructed in the manual. This leads to reduced efficiency, which also contributes to increased power consumption. Today, the peak of power consumption occurs in the midsummer afternoon, and if the power efficiency of home air conditioners is improved, it is not necessary to newly install power generation equipment, and the efficiency of existing equipment will be improved.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and an object of the present invention is to provide an air conditioner having a disposable filter which can be easily replaced. It is in.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an air conditioner in which a filter roll having a long filter wound in a coil shape is rotatably housed, and a filter roll housed in the filter chamber. A guide path for guiding the filter drawn out of the filter so as to cover the intake port and guiding the free end side of the filter past the intake port to the outside, and a cutter device for cutting off the contaminated filter are provided. This is achieved by pulling out a predetermined area on the free end side of the filter when it becomes dirty, drawing out the filter from the filter roll, updating the filter covering the air inlet, and cutting off the dirty filter.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing an embodiment of an air conditioner provided with a disposable filter according to the present invention, FIG. 2 is a front view showing a state in which a lid of the air conditioner shown in FIG. 1 is omitted, and FIG. 4 is a cross-sectional view showing a state in which a filter roll is mounted on the air conditioner shown in FIG. 3, and FIG. 5 is a top view showing a rotating state of the cutter device of the air conditioner shown in FIG. It is. In the figure, the air conditioning mechanism inside the casing is omitted. In the figure, 1 is a filter roll, 2 is a casing, 3 is a lid, and 4 is a cutter device.

First, FIGS. 1 to 3 will be described.
The filter roll 1 is obtained by winding a long filter 10 around a core 11. The casing 2 has a substantially horizontal rectangular parallelepiped shape, and as shown in FIG. 3, a stepped portion 2 b concaved in an L-shaped cross section along a portion of the upper edge of one long side surface 2 a excluding a predetermined region from both ends. In a region excluding a predetermined region along the lower edge of the long side surface 2a and a predetermined region along the left and right side edges, a concave surface 2c which is recessed one step shallower than the predetermined region of the peripheral edge and communicates with the step portion 2b is provided. Having. Bearings 2d and 2e are provided at both ends of the stepped portion 2b, and an intake port 2f is provided near the center of the concave surface 2c as shown in FIG. An air outlet 2h is provided.

The lid 3 is a member having a substantially J-shaped cross section which can cover most of the recessed portion of the casing 2, and as shown in FIG. A predetermined distance from the lower edge of the concave surface 2c is rotatably supported on a horizontal axis passing through the concave surface 2c via a predetermined gap. The flat plate portion 3a of the lid 3 faces the concave surface 2c of the casing 2 via a small gap, and an intake window 3b formed of a number of slits is provided near the center of the flat plate portion 3a.

The cutter device 4 includes a guide rail 40 and a roller cutter 41. The guide rail 40 is a long member having a guide hole 40a elongated in the longitudinal direction at the center thereof, and is horizontally arranged between the lower edge of the concave surface 2c of the casing 2 and the lower edge of the lid 3. And, as shown in FIG. 5, one end thereof is locked to the casing 2 via a vertical rotating shaft. The roller cutter 41 has a disk-shaped rotary blade rotatably mounted on one surface of the support member, and the rotary blade can be in contact with the concave surface 2 c of the casing 2.
The guide rail 40 is fitted into the guide hole 40 a and is slidably held in the longitudinal direction of the guide rail 40. The cutter device 4 is configured such that the end that is not normally supported by the shaft is locked by the casing 2 so as not to be opened carelessly, and the roller cutter 41 is rotated by a locking means (not shown). It is locked to the side end so that it does not slide carelessly.

In this air conditioner, when the lid 3 is closed, the space defined by the lid 3 and the step 2b becomes a filter chamber, and the gap between the lid 3 and the concave surface 2c is a guide path for the filter 10. It is what becomes. Thus, when using this air conditioner, as shown in FIG. 4, the lid 3 is opened, the ends of the core 11 of the filter roll 1 are fitted to the bearings 2d and 2e, and the filter roll 1 is mounted. Grip the filter 10 and pass its free end between the lower edge of the lid 3 and the concave surface 2c,
After the end protrudes downward from the lower edge of the lid 3, the lid 3 is closed, the filter 11 is held in the guide path, and the air conditioning mechanism inside the casing 2 (not shown) is operated.

When the contamination of the filter 10 progresses, as shown in FIG. 5, the cutter device 4 is opened, the end of the filter 10 is grasped, and the cutter device 4 is closed slightly. The filter 10 is pulled out by a distance sufficient to update the filter 10 and brought into the state shown in FIG. 1, and finally the filter 10 is cut by sliding while pressing the roller cutter 41 to thereby remove the filter housed in the filter chamber. Roll 1 filter 10
The filter 10 can be easily updated any number of times until the error disappears.

The present invention is not limited to the above embodiment. For example, the filter may be extended upward, leftward, rightward, or obliquely. May be guided along a plurality of surfaces. Also, on the bearing,
A stopper may be provided to allow the filter roll to rotate when the filter is continuously pulled out for a predetermined distance, or the filter may be extended using power from a motor or the like.

Further, the filter may be fixed by, for example, providing a projection protruding toward the casing at the upper edge side of the guide rail of the cutter device and pressing the filter against the concave surface 2c when the cutter device is closed. Often,
Further, the guide path may be provided inside the casing, and a lid may be provided independently of the guide path.Furthermore, the shape of the casing, the lid, the shape and the mechanism of the cutter device may be freely set within the scope of the present invention. The present invention encompasses all modifications that can be easily made by those skilled in the art from the above description without departing from the scope of the present invention.

[0013]

Since the air conditioner provided with the disposable filter according to the present invention is constructed as described above, according to the present invention, it is possible to renew the contaminated filter very easily. As a result, the efficiency of the air conditioner is maintained at a high level, and there is no waste of electricity, so that there is also an effect that new installation of power generation equipment is suppressed and efficiency of existing power generation equipment is increased.
