Further, support shaft holes 16e are formed on the upper and lower surfaces of the brush holding case 16. The support shaft 18d of the stop brush 18 is inserted in this support shaft hole 16e, and the stop brush 18 is hold | maintained by the brush holding case 16. As shown in FIG.

On the inner side of one side of the brush holding case 16, the stop brush engaging portion 16b is formed to protrude. The engaging portion 18c of the stationary brush 18 is coupled to the stationary brush engaging portion 16b, whereby the stationary brush 18 is held in the state of the brush holding case 16 in a stationary state. On the inner side of the other side surface of the brush holding case 16, the sliding part 16f protrudes over the full width of the side surface, and the rotation restraint part 16d is formed in the front-end | tip part.

Moreover, the dust box catching part 16c which consists of a some hook is formed in the left and right both sides of the brush holding case 16. As shown in FIG.

The arm 17 is equipped with the 1st arm part 17a, the 2nd arm part 17b, and the rotating shaft coupling hole 17c. This arm 17 is arrange | positioned inside the brush holding case 16, and is rotatably supported by the rotating shaft 15c3 by fitting the rotating shaft 15c3 to the rotating shaft coupling hole 17c. The 1st arm part 17a and the 2nd arm part 17b are radially extended centering on the rotating shaft coupling hole 17c, and are formed in two branch shape.

The spring 20 consists of three types of springs, namely, the rotation brush spring 20a, the arm spring 20b, and the stop brush spring 20c.

The rotary brush spring 20a rotates the rotary brush 15, and the cleaning brush 15a and the discharge brush 15e pass through the recovery brush 18a side and are stored in the brush holding case 16. The rotary brush stand 15c is rotated in the direction. That is, the rotary brush 15 is rotated in the direction of the stationary brush 18 by the force of the spring 20a for the rotary brush, and the shock absorbing member 15f of the rotary brush stand 15c is the brush holding case ( The rotation is stopped by contacting the rotation suppressing portion 16d provided in 16). In order to suppress the collision sound of the rotation brush stand 15c and the rotation suppressing part 16d, the impact sound absorption member 15f is provided in the part used as the contact part of the rotation brush stand 15c, and a shock is absorbed, At the same time, the damage to components is suppressed.

The arm spring 20b is such that the convex portion 17d of the arm 17 is always in contact with the convex portion 15c5 of the rotary brush stand 15c as long as no external force is applied to the arm spring 20b. The arm 17 is pressed.

The stop brush spring 20c presses the stop brush 18 against the rotary brush stand 15c as long as no external force is applied to the stop brush spring 20c.

The dust box 19 is comprised with the elongate resin box-shaped member, and the front surface is open. A plurality of brush holding case engaging holes 19a are formed in the left and right sides of the dust box 19. The dust box 19 is held by the brush holding case 16 by the dust box engaging portion 16d engaging the engaging hole 19a.

The side shape of the dust box 19 becomes substantially triangular so that it may substantially correspond with the substantially triangular shape seen from the side surface of the space behind the rear heat exchanger part 9a. With such a configuration, the dust storage amount of the dust box 19 can be increased without increasing the housing 30.

In addition, since the dust box 19 is positioned and moved along the rear surface of the inclined filter 11, the dust box 19 falls from the filter 11 when cleaning the dust collected by the filter 11 with the cleaning brush 15a. When there is dust, it can be received by the slide stand 16f and stored in the dust box 19 as it is.

Next, operation | movement of the cleaning part 13 is demonstrated, referring FIGS. 10A-10H.

FIG. 10A shows a state of the standby state of the cleaning unit 13 (when the cleaning device 5 is stopped) in the air conditioner 1 of FIG. 2, and when the air conditioner 1 is stopped. It is a state at the time of stopping the filter cleaning function during the operation of the air conditioner 1.

In this standby state, the first arm portion 17a is disposed in a state of not being constrained in the first recessed portion 6h of the support 6, and the second arm portion 17b is spaced apart from the support 6. It is arranged. Here, since the rotational force is applied to the rotation brush 15 in the direction (clockwise direction) of the stop brush 18 by the rotation brush spring 20a, it rotates in the direction of the stop brush 18, and the rotation brush stand The shock absorbing member 15f of 15c is rotated and stopped until it comes in contact with the rotation suppressing portion 16d of the brush holding case 16. Moreover, even after the rotation brush 15 stops rotating, the rotation brush 15 can maintain the rotation stop state by applying tension to the rotation brush 15 while leaving the tension of the rotation brush spring 20a. have. In the standby state of FIG. 10A, since the cleaning brush 15a does not interfere with other parts, the deformation of the hair can be minimized.

FIG. 10B is a cross-sectional view showing a state of the cleaning unit 13 immediately after the operation of the cleaning device 5 is started from FIG. 10A.

When the operation of the cleaning device 5 is started, the drive motor 34 of the drive unit 14 is started to rotate the transmission shaft 35, and the rotation of the transmission shaft 35 is transmitted to the worm gear 36. . Since the worm gear 36 is held by the worm gear suppressing portion 13a, the cleaning portion 13 starts to move in the backward travel direction of the arrow in FIG. 10B.

When the cleaning part 13 starts moving, the 1st arm part 17a is made to contact the corner part of the 1st recessed part 6h by the 1st arm part 17a which was released in the 1st recessed part 6h. Is rotated counterclockwise, and the convex portion 17d of the arm 17 and the convex portion 15c5 of the rotary brush stand 15c are brought into contact with each other so that the rotary brush 15 is rotated by the spring 20a for the rotary brush. It is rotated counterclockwise against the rotational force of. As the rotary brush 15 rotates, the cleaning brush 15a and the discharge brush 15e are rotated in the direction of the filter 11 (counterclockwise) to stand up. Moreover, with the rotation of the arm 17, the 2nd arm part 17b also rises and enters into the 2nd recessed part 6i provided in the support body 6 adjacent to the 1st recessed part 6h.

FIG. 10: C is sectional drawing which shows the cleaning part 13 of the state which the operation | movement of the cleaning apparatus 5 further advanced from FIG. 10B.

If the cleaning part 13 is further moved from FIG. 10B, the second arm part 17b released in the second concave part 6i contacts the corner part of the concave part 6i, whereby the second arm part 17b. ) Is rotated counterclockwise. Thereby, the rotation brush 15 is further rotated counterclockwise against the rotational force of the spring 20a for rotation brushes, and the cleaning brush 15a and the discharge brush 15e further rotate and stand up.

As a result, the cleaning brush 15a stands up from the rotary brush stand 15c at a right angle with respect to the filter 11, and the filter 11 can be cleaned, while the second arm portion 17b supports the support. The arm contact surface which is the surface of (6) is in the state which slides.

In the present embodiment, as described above, the arm 17 is composed of two stage arm portions of the first arm portion 17a and the second arm portion 17b, and the relationship between the adjacent recesses 6h and 6i. By rotating together with the gears, it is possible to obtain a large rotation angle of the arm 17 and the rotary brush 15 by using the arm 17 having a small good rotation radius of the space factor.

When the cleaning unit 13 is further moved, the tip of the cleaning brush 15a contacts the filter 11 and is deformed in the anti-forward direction, and the dust collected by the filter 11 is cleaned and collected by the cleaning brush 15a. .

In this case, in order to prevent the cleaning brush 15a from rotating more than necessary by friction with the filter 11, the cleaning brush 15c is brought into contact with the rotation suppressing portion 16d at a predetermined position, thereby cleaning. The rotation of the brush 15a is suppressed. Moreover, the angle which restrains rotation of the cleaning brush 15a is made to allow it to rotate further from the angle which the cleaning brush 15a and the filter 11 become a right angle. The reason for this is to prevent damage to the component parts due to the compressive force and the shear force even when the cleaning device 5, the filter 11 and the rails 12a and 12b are difficult to deform or precisely move in parallel. to be.

When the cleaning brush 15a moves, there is a possibility that dust collected through the cleaning brush 15a may fall from the filter 11 without being collected by the cleaning brush 15a. Therefore, in this embodiment, even if the slide 16b is provided in the side surface of the brush holding case 16 on the side of the half path progress direction, even if the dust which passed through the cleaning brush falls from the filter 11, the sliding part ( It is received in 16f) and guided in the dust box 19. As shown in FIG.

FIG. 10D is a cross-sectional view showing the cleaning unit 13 in which the cleaning unit 5 further advances from FIG. 10C and the cleaning unit 13 reaches the reciprocating return point, and FIG. 10E is an operation of the cleaning device 5 from FIG. 10D. It is sectional drawing which shows the cleaning part 13 of this further advanced state.

When the cleaning part 13 reaches a reciprocating return point, the 2nd arm part 17b which was in contact with the arm contact surface of the support body 6 enters into the 3rd recessed part 6j provided in the return point of the support body 6, and with other components. Of interference is eliminated. Thereby, the arm 17 is rotated clockwise by the rotational force of the arm spring 20b, and the rotary brush 15 is rotated clockwise by the rotational force of the rotational brush spring 20a.

By rotation of the rotary brush 15, the discharge brush 15e is rotated clockwise while being rubbed with the recovery brush 18a. Here, since the hairs of the discharge brush 15e and the recovery brush 18a face each other inclined downward (toward the bottom of the dust box 19), the dust collected and attached to the recovery brush 18a is discharged. It is scraped off by the brush 15e and discharged into the dust box 19.

Moreover, by the rotation of the rotation brush 15, the cleaning brush 15a is delayed rather than the discharge brush 15e, and is rubbed by the collection | recovery brush 18a, and rotation operation is performed. Here, as shown in FIG. 10D, since the cleaning brush 15a is deformed to the side opposite to the direction of the recovery brush 18a, most of the dust attached to the cleaning brush 15a is transmitted to the recovery brush 18a. Without work, it is moved with the cleaning brush 15a.

And when the cleaning brush 15a passes the uneven part 18e of the stop brush 18, the recessed part 18e functions as a comb, a part of dust will be transmitted to the uneven part 18e, and the dust A part of is dropped in the dust box 19, and the remaining dust is attached to the cleaning brush 15a. Then, the discharge brush 15e and the cleaning brush 15a are further rotated to be stored in the brush holding case 16 and the dust box 19, and the shock absorbing member 15f contacts the rotation suppressing portion 16d. Rotation is stopped and it will be in the state shown in FIG. 10E.

10F is a cross-sectional view showing the cleaning unit 13 immediately after the operation of the cleaning apparatus returns to the return from FIG. 10E, and FIG. 10G shows the cleaning unit 13 in a state where the operation of the cleaning apparatus further progresses in the return from FIG. 10F. It is a cross section.

When the cleaning part 13 starts advancing from the state of FIG. 10E, the inclined surface side of the 1st arm part 17a contacts the support body 6, as shown in FIG. 10F.

When the cleaning unit 13 proceeds further, the cleaning unit 13 moves against the force of the arm spring 20b that is pressing the convex portion 15c5 of the rotary brush stand 15c and the convex portion 17d of the arm 17. The support 6 is pressed against the 1 arm part 17a. Thereby, in the cleaning part 13, the cleaning brush 15a and the discharge brush 15e are accommodated in the brush holding case 16 and the dust box 19 as shown in FIG. 10G in a return path. It is moved while it is, and it returns to a standby state. In this way, by storing the cleaning brush 15a in the brush holding case 16 at the time of returning, and not making contact with the filter 11, the direction of movement of dust becomes one direction, and dust can be prevented from being wiped out. Can be.

FIG. 10H is a cross-sectional view showing the cleaning part 13 immediately after the operation of the cleaning device 5 is started again after the cleaning part 13 returns to the standby position from FIG. 10G.

When the operation of the cleaning device 5 is started again, the operation of the cleaning unit 13 described in FIG. 10B is performed. By the rotation of the rotating brush 15, the dust left in the uneven part 18b can be attached to the back of the path | route progress direction of the cleaning brush 15a this time. Moreover, although the cleaning brush 15a contacts the collection | recovery brush 18a again by rotating the rotating brush 15, when the cleaning brush 15a rotates to the filter 11 direction and stands up, the collection brush 18a of Since the rub is rubbed against each other in the opposite direction, the dust is attached to the recovery brush 18a, and the cleaning brush 15a can clean the filter 11 in a neat state during the next filter cleaning.

The dust attached to the recovery brush 18a is attached to the rotary brush stand 15c when the rotary brush 15 is rotated in the direction of the dust box 19 as shown in FIG. 10D. By the discharge brush 15e, it sweeps in the direction of the dust box 19. As shown in FIG. This is because the discharge brush 15e and the recovery brush 18a are rubbed with each other, but the hair of the discharge brush 15e is aligned in the direction of the dust box 19 like the recovery brush 18a. As a result, when the rotary brush 15 stands up in the direction of the filter 11, the dust attached to the recovery brush 18a is not affected, but the rotary brush 15 is in the direction of the dust box 19. When rotating, since the discharge brush 15e is reversed, the dust attached to the collection brush 18a can be swept away to the dust box 19.

Although the dust collected by the filter 11 can be transmitted to the dust box 19 by the above series of operations, in order to collect dust to the dust box 19 more reliably and efficiently, the cleaning apparatus 5 The cleaning part 13 which has the dust box 19 which stores the dust cleaned from the filter 11 by the rotating brush and the rotating brush 15 is provided, The cleaning part 13 wash | cleans the dust collected by the filter 11, After the cleaning operation, the short distance reciprocating operation is repeated a plurality of times so that the dust attached to the rotary brush 15 is dropped onto the dust box 19. Specifically, after one round trip of the cleaning unit 13 by filter cleaning, the discharge brush 15e and the recovery brush 18a are rubbed each other a plurality of times.

Next, the dust disposal method accumulated in the dust box 19 by filter cleaning is demonstrated.

The cleaning part 13 is detachably supported by the support body 6, and can remove the cleaning part main body 37 from the cleaning apparatus 5 at the time of dust disposal. Since the whole cleaning part main body 37 is removed integrally, the problem of scattering the dust accumulated in the dust box 19 can be solved.

As shown in FIG. 11, the dust box 19 and the brush holding case 16 are detachable, and the dust box 19 is removed by removing the dust box 19 from the brush holding case 16. 19) Dust accumulated in the waste can be discarded.

12 and 13, an opening 19b is provided on the lower surface of the dust box 19. The opening 19b is exposed to the air intake port 30a in a state where the intake panel 4 is opened. By inserting and sucking the nozzle 25 of the vacuum cleaner into this opening, dust can be easily discarded without removing the cleaning part 13 from the ceiling-mounted air conditioner 1.

In the state where the nozzle 25 is not inserted into the opening 19b of the dust box 19, since the opening is blocked by the rotatable cover 24, dust in the dust box 9 leaks from the opening. There is nothing to be done. By pressing the cover 24 at the tip of the nozzle 25, the cover 24 is rotated so that the tip of the nozzle 25 can be inserted into the opening.

Moreover, since the guide 25a is provided in the nozzle 25, the tip of the nozzle 25 can be guide | induced to the opening 19b of the dust box 19 using this guide 25a. By bringing the guide 25a into contact with the decorative panel 3, for example, it is possible to prevent an excessive force from being applied by the operator and to prevent damage to the component parts.

According to the present embodiment, when dust is deposited on the filter 11, the cleaning brush 15a is the filter 11 in a path in which the cleaning part 13 including the rotary brush 15 moves from one side to the other side. Cleaning). Moreover, at the return point, the dust collected and attached to the collection brush 18a at the time of the previous filter cleaning is dropped onto the dust box 19 by the discharge brush 15e, and the dust collected at the time of this filter cleaning is collected. By attaching to the collection brush 18a after the discharge brush 15e has passed, the filter cleaning operation can be performed easily without passing through a human hand. In addition, by storing the filter 11, the cleaning part 13, and the drive part 14 inside the housing 2, the filter cleaning function can be mounted without changing the dimensions of the conventional ceiling-embedded air conditioner.
