  Moreover, the air conditioner of this invention rotates a rotary heat exchanger, the air filter provided in the upstream of this heat exchanger, the rotary rotor for air conditioners of Claim 1, and this rotary rotor. The rotary drive means and the rotary rotor are arranged on the upstream side of the air filter and are moved along the surface of the air filter.

  The rotary rotor for an air conditioner according to the present invention does not need to replace the entire rotary rotor for an air conditioner when the cleaning body is exhausted, and only the cleaning body needs to be replaced. The maintenance cost of the air conditioner equipped with is reduced.

  The present invention is a rotary rotor for an air conditioner that removes dust accumulated on an air filter attached to an air conditioner, the rotor being rotatable, and a groove provided in the longitudinal direction of the outer periphery of the rotor. One end can be inserted into and removed from the groove, and the other end is equipped with a cleaning body that scrapes off dust accumulated on the air filter. One end of the cleaning body can be inserted into and removed from the groove of the rotor. Assembling of the rotary rotor for machines is easy.

  In addition, since the dust on the mesh air filter is scraped off by the cleaning body, the cleaning body is heavily consumed, but one end of the cleaning body can be inserted into and removed from the groove provided in the longitudinal direction of the outer periphery of the rotor. When the air is exhausted, it is not necessary to replace the entire rotary rotor for the air conditioner, and only the cleaning body needs to be replaced, so the maintenance cost of the air conditioner is low. In addition, since the cleaning body can be inserted into and removed from the rotor, various types of cleaning bodies, for example, cleaning bodies with different materials and hardness, can be prepared as needed, and the rotors can be shared and used freely. it can.

  In the present invention, in particular, the groove portion is formed in a spiral shape in the longitudinal direction of the outer periphery of the rotor, and by inserting one end of the cleaning body into the groove portion spirally provided in the longitudinal direction of the outer periphery of the rotor, The other end of the cleaning body, that is, the front end of the cleaning body is spiraled, whereby the front end of the cleaning body comes in partial contact with the air filter, and the sliding resistance is dispersed, thereby rotating the rotary rotor for the air conditioner The current consumption of the driving means for rotationally driving can be reduced, and the filter can be cleaned uniformly without unevenness.

  In the present invention, in particular, the rotor is formed of a metal material, the strength of the rotor is increased, and accordingly, the rotor can be formed with a small diameter, thereby saving space. In particular, in a generally horizontally long body such as an air conditioner, since the air filter is long, a long rotor rotor is also required, but the rotor is made of a metal material. By forming, it becomes easy to secure the required strength. In addition, deformation such as warpage is less likely to occur, and the cleaning efficiency is improved by a rotary rotor for an air conditioner with good finishing accuracy.

  The present invention includes a heat exchanger, an air filter provided on the upstream side of the heat exchanger, and the above-described rotary rotor for an air conditioner, and is a cleaning body on a mesh-like air filter. The cleaning body is worn out heavily to scrape off dust, but one end of the cleaning body can be inserted into and removed from the groove provided in the longitudinal direction of the outer periphery of the rotor. There is no need to replace the air conditioner, and only the cleaning body needs to be replaced, so the maintenance cost of the air conditioner is low.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

Example 1
FIG. 1 is a longitudinal sectional view of an air conditioner equipped with a rotary rotor for an air conditioner according to a first embodiment of the present invention. FIG. 2 is a perspective view of the rotary rotor for the air conditioner. FIG. 4 is a perspective view showing an outline of the internal configuration of the air conditioner.

  In FIG. 1, the air conditioner main body 15 is disposed between the heat exchanger 16, a suction port 17 for taking in indoor air, the heat exchanger 16 and the suction port 17, and flows from the suction port 17. An air filter 18 that collects dust contained in the air, and an air conditioner rotary rotor 20 that is disposed upstream of the air filter 18 and that removes dust collected by the air filter 18 (hereinafter referred to as the air filter 18). , "Rotary rotor 20"), rotational drive means (not shown) for rotationally driving the rotary rotor 20, and moving the rotary rotor 20 in the vertical direction along the upstream surface of the air filter 18. The indoor air is sucked from the up-and-down moving means (not shown) and the suction port 17, and the heat-exchanged air is passed through the air filter 18 and the heat exchanger 16 from the outlet 21. And a fan 22 for blowing.

Next, the configuration of the rotary rotor 20 will be described with reference to FIGS.
2 and 3, the rotary rotor 20 is made of a metal material such as aluminum, and scrapes off the dust attached to the air filter 18 and the rotor 26 having grooves 25 formed in a spiral shape in the outer periphery and in the longitudinal direction. The cleaning body 27 is composed of a cleaning body 27 and a cap 28 for preventing the cleaning body 27 from coming off. The cross-sectional shape of the groove 25 is substantially T-shaped as shown in FIG. In the present embodiment, the maximum rotational outer diameter dimension of the rotor 26 is set to 10 mm or less so that the diameter is small, so that the rotary rotor 20 is not increased in size.

  The cleaning body 27 includes a base portion 27a that can be inserted into and removed from the groove portion 25, and a brush member 27b that is implanted in the base portion 27a and includes a plurality of fibers. The brush member 27b is not limited to a plurality of fibers and may be formed of a blade-like material made of a soft material such as rubber. Further, in the single body state, the cleaning body 27 is linear as shown in FIG. 3, but the brush 27 of the cleaning body 27 is inserted by inserting the base portion 27 a into the spiral groove 25 of the rotor 26. The member 27b is provided on the outer periphery of the rotor 26 in a spiral shape.

Next, several methods for manufacturing and processing the rotor 26 will be described.
The first method is a method of extruding while twisting the material of the rotor 26 with a torsion extrusion mold, and it is possible to finish the target torsion angle in one step. However, warpage and undulation are likely to occur, and it is difficult to ensure accuracy, and this tendency becomes more prominent as the torsion angle increases. The torsion angle is limited to about 360 degrees, and beyond that, it is practically a product. Don't be.

  The second method is to extrude the material of the rotor 26 while twisting it with a mold, to make a rotor 26 having an angle smaller than the target twist angle, and to twist the rotor 26 to the target twist angle by post-processing. Since it is finished and post-processing is minimized, the cross-sectional distortion is small and the rotor 26 with high accuracy can be manufactured. The only drawback is that the process is in two stages.

  The third method is to extrude the material of the rotor 26 straight and finish by twisting to the target twist angle in post-processing, and the accuracy of the product material in one process (linear extrusion) is very high. Originally, the rotor 26 is twisted by post-processing, so that the rotor 26 can be manufactured with high accuracy and small distortion caused by twisting. Further, the twist angle of the rotor 26 can be freely set even in the same mold by post-twisting. As a disadvantage, hollow materials and large-diameter materials are easily deformed in cross-section by twisting, and are not suitable for a large twist angle.

  The fourth method is a production method in which equipment such as a movable plate that rotates in the twisting direction is provided on the same line, while the material of the rotor 26 is extruded with a die, and at the same time, twisting is performed to finish the target twisting angle. There is no need to provide a separate twisting process, and there is a merit that the twisting angle can be freely set by the rotational speed of the movable platen, but there is a disadvantage that the equipment becomes complicated.

  Therefore, in manufacturing the rotor 26, it is preferable to appropriately determine the manufacturing method and the processing method in consideration of the cross-sectional shape, material, thickness, strength, torsion angle, required accuracy, and the like of the rotor 26.

  In the present embodiment, the rotary rotor 20 is provided in the air conditioner main body 15 so as to face each of the two air filters 18 that are divided into two. Further, since the width of one of the air filters 18 mounted on the air conditioner having a standard cooling capacity is 300 mm or more, in this embodiment, the effective cleaning width L (rotary rotor 20 obtained by one rotation of the rotary rotor 20). The overall width dimension of the cleaning body 27 attached to the head is set to 300 mm or more.

Next, the operation of the rotary rotor 20 in this embodiment and the air conditioner equipped with the rotor 20 will be described.
When the air conditioner main body 15 is in a cooling operation, for example, indoor air flows from the suction port 17 by the fan 22, passes through the air filter 18, reaches the heat exchanger 16, and is cooled there. 21 is blown into the room. Dust contained in indoor air sucked from the suction port 17 is collected by the air filter 18 and gradually accumulates on the surface of the air filter 18. When dust accumulates on the surface of the air filter 18, air pressure loss of the air increases, and the heat exchange efficiency in the heat exchanger 16 decreases. Therefore, the air filter is periodically or as necessary. The operation of removing the dust accumulated on 18 is required.

  At the start of the dust removal operation, the rotary rotor 20 is positioned at the lower end of the air filter 18 as shown in FIG. When the dust removal operation is started, the rotary rotor 20 is rotated in the direction of the arrow by the rotation driving means (not shown), and the rotating rotor 20 is moved up and down by the vertical movement means (not shown). Move upward along. During this time, dust adhering to the air filter 18 is scraped off at the tip of the brush member 27b of the cleaning body 27. The dust scraped off is sucked by a dust suction means (not shown) and discharged to the outdoors.

  When the rotary rotor 20 reaches the upper end of the air filter 18 by the vertical movement means, it automatically descends and stops at the lower end of the air filter 18 for the next dust removal operation.

  As described above, according to the present embodiment, since the base portion 27a of the cleaning body 27 can be inserted into and removed from the groove portion 25 of the rotor 26, the assembly of the rotary rotor 20 is easy. The cleaning body 27 scrapes off the dust on the mesh-like air filter 18, so that it is heavily consumed. When the body 27 is exhausted, it is not necessary to replace the entire rotary rotor 20, and only the cleaning body 27 is replaced. Therefore, the maintenance cost of the air conditioner is low.

  Further, since the cleaning body 27 can be inserted into and removed from the rotor 26, various kinds of cleaning bodies 27, for example, cleaning bodies 27 having different materials and hardness, are prepared as required, and the rotor 26 is used in common. You can also use them freely. For example, the cleaning body 27 can be formed of a soft material such as rubber so that the surface of the air filter 18 is hit.

  Further, since the groove portion 27a is formed in a spiral shape in the longitudinal direction of the outer periphery of the rotor 26, the other end of the cleaning body 27, that is, the other end of the cleaning body 27 can be obtained by inserting the base portion 27a that is one end of the cleaning body 27 into the groove portion 27a. The tip of the brush member 27b is arranged in a spiral shape, so that the tip of the brush member 27b comes into partial contact with the air filter 18, the sliding resistance is dispersed, and the rotational drive means for rotationally driving the rotary rotor 20 is used. The current consumption can be reduced, and the air filter 18 can be uniformly cleaned without unevenness.

  Further, by forming the rotor 26 with a metal material, the strength is increased, and accordingly, the rotor 26 can be formed with a small diameter, thereby saving space. In particular, in a generally long air conditioner main body 15 such as an air conditioner, the air filter 18 is long. Therefore, the rotary rotor 20 needs to be long. By forming with a metal material, it becomes easy to secure the required strength. Further, deformation such as warpage is less likely to occur, and the cleaning efficiency is improved by the rotary rotor 20 with good finishing accuracy.

  In addition, by setting the maximum rotation outer diameter of the rotor 26 to 10 mm or less, the rotor 26 has a minimum diameter, and the air conditioner body 15 in which the rotary rotor 20 is incorporated can be easily reduced in thickness.

  In addition, by setting the effective cleaning width obtained by one rotation of the rotary rotor 20 to 300 mm or more, the single air filter 18 can be reliably cleaned by the single rotary rotor 20.

  Further, the cleaning body 27 is worn by providing the rotary rotor 20 in this embodiment in the air conditioner body 15 incorporating the heat exchanger 16 and the air filter 18 provided on the upstream side of the heat exchanger 16. At this time, it is not necessary to replace the entire rotary rotor 20, and only the cleaning body 27 needs to be replaced. Therefore, the maintenance cost of the air conditioner is low.

  As described above, the rotary rotor for an air conditioner and the air conditioner according to the present invention do not need to replace the entire rotary rotor for an air conditioner when the cleaning body is consumed, and only the cleaning body needs to be replaced. Therefore, the maintenance cost of the air conditioner is reduced, and it can be applied to various devices having an air filter such as an air purifier and a ventilator as well as various air conditioners for home use and business use.
