Abstract

PURPOSE:To save a cleaning of a filter and reduce a troublesome operation by a method wherein the filter is arranged along a suction port between cylindrical rollers at both ends and the filter is wound around one roller under a driving of a gear combined with a motor. CONSTITUTION:Cylindrical rollers 20 and 21 having a filter 22 wound therearound are provided at right and left sides of a heat exchanger 15 for an indoor device. The rollers 20 and 21 are constructed such that they are periodically wound up under an operation of a switch 26 in such a way as they are rotated by a motor and a gear. As dusts are adhered to the filter 22 to cause an amount of aeration air to be reduced, the switch 26 is turned on, the filter is wound up and no cleaning is required. As the filter 22 is washed with water, it takes time for drying the same. However, the cylindrical wound filter 22 is always clean of dusts while its dust adhering part being wound up and an air conditioning operation can be carried out, a reduction in an amount of air is not found and the air conditioning can be always carried out while being in a good condition.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a filter device for an air conditioner or the like.

Conventional technology Conventionally, air conditioners have used filters at their air intake ports to purify the air, but this filter device had the configuration shown in Figures 6 and 7. .

That is, in FIG. 6, the indoor air sucked in by the operation of the blower 4 through the suction port 3 of the front panel 2 provided on the front side of the main body 1 of the wall-mounted indoor unit is heated after dust is removed by the filter 6. The air flows through the exchanger 6, is heated or cooled, and is discharged back into the room through the blow-off lower to air-condition the living room. As shown in FIG. 6, the filter 5 still has a structure in which a filter material 9 is welded to a filter frame 8. Further, in order to prevent the filter 6 from falling off, a protrusion 1° shown in FIG. 7 and a knob 11 are integrally formed with the filter frame 8. When inserting the filter 5 into the air conditioner, hold the knob 11, insert the filter between the front panel 2 and one of the filters 12, and forcibly push it upward. /
It was held so as to be connected to the L-20 receiving part 13.

Problems to be Solved by the Invention In such a conventional configuration, dust is removed from the indoor air sucked through the suction port 3 by the filter 5, so if the filter material 9 of the filter 5 is used for several days, dust will accumulate on the filter material 9 of the filter 5. will adhere and cause clogging, reducing the amount of air passing through.
Since the heating or cooling ability is adversely affected, the filter 6 must be removed and cleaned periodically by washing with water, which poses a problem in that it is time-consuming and complicated to attach and remove and wash with water.

The present invention is intended to solve these problems, and aims to reduce the complexity by eliminating cleaning such as washing the filter with water.

Means for Solving the Problem In order to solve this problem, the present invention includes a front panel having a suction port on the front surface of the main body, a heat exchanger inside the main body, and a heat exchanger located at both left and right ends of the heat exchanger.

It has a right filter storage part and a left filter storage part, and each of the filter storage parts has an upper shaft and a lower shaft, and is held by the upper shaft and the lower bearing, and has a cylindrical roller at both ends around which the filter is wound. A filter is installed along the suction port between the cylindrical rollers at both ends, and a combination gear and a motor are provided at the bottom of the lower bearing of one of the cylindrical rollers, and the motor and combination gear are driven. By doing so, the filter is wound onto one of the rollers.

Function: With this configuration, if the filter becomes dirty with dust, etc.,
In order to make the filter wrapped in a long band around the cylindrical rollers on the left and right sides of the suction side of the heat exchanger into a new filter, the motor is driven to wind up the dirty area of the filter and to unwind the new filter. Dust is removed by the area of the suction port of the heat exchanger, which allows the dust to be removed while operating in a state with little clogging.

Panel 17 and heat exchanger 1
Indoor air is sucked in by the operation of a blower (not shown) through the suction port 23 of the 011 face panel 17, and after dust is removed by the filter 22, it passes through the heat exchanger 16. The heated or cooled air is then discharged into the room from the air outlet 35 to air-condition the living room. During such operation, as dust adheres to the filter 22, a considerable amount of clogging occurs, and in that case, the front panel 1

During winding, the contact piece A25 of the switch 2θ enters the notch 38 of the filter 22, and at the same time, the contact piece B35 separates from the contact point (not shown) inside the switch 26, the motor 33 stops, and the filter 22 is wound up. It will end. Further, a front cover 36 is provided to prevent dust from diffusing inside the product when the filter 22 with one dust layer is wound around the cylindrical roller 20.

As a result, cleaning of the filter 22 is eliminated.

Next, the filter 2 wound around the cylindrical roller 21
2, remove the front panel 17, remove the dirty filter 22 from the right filter storage part 18, and remove the dirty filter 22 from the cylindrical roller 20. is removed from the left filter storage part 19 and inserted between the upper shaft 28 and the lower shaft 29 of the right filter storage part 18. Then, insert a new filter wrapped around the cylindrical roller of the replacement port between the upper and lower shafts (not shown) of the left filter storage part 19, insert the filter into one filter 24, and insert the filter into the suction port 23. By tensioning the entire filter and wrapping the tip of the filter around the cylindrical roller 21 of the right filter housing 18, it can be easily replaced.

Effects of the Invention As is clear from the description of the embodiments described above, the present invention includes cylindrical rollers wrapped with filters on the left and right sides of the heat exchanger of the indoor unit, and these rollers are rotated by a motor and gears. The filter is wound up periodically, so when dust accumulates on the filter and the amount of airflow decreases, just flip the switch and the filter will be wound up, eliminating the need for cleaning. Also, if you wash the filter with water as in the past, it takes time to dry the filter, but with a filter that is wound into a cylindrical shape like the one in this example, only the part that has dust is rolled up. This has the effect that air conditioning can always be performed using a filter with little dust, and there is no drop in air volume, so that air conditioning is always maintained in good condition.
