A stationary brush engaging portion 16 b is formed to protrude inside one side surface of the brush holding case 16. The stationary brush 18 is held stationary on the brush holding case 16 by the engagement portion 18 c of the stationary brush 18 being engaged with the stationary brush engaging portion 16 b. Inside the other side surface of the brush holding case 16, a slide portion 16f is formed so as to protrude over the entire width of the side surface, and a rotation suppression portion 16d is formed at the tip thereof.

Further, dust box engagement portions 16c formed of a plurality of claws are formed on the left and right side surfaces of the brush holding case 16.

The arm 17 includes a first arm portion 17a, a second arm portion 17b, and a rotation shaft engagement hole 17c. The arm 17 is disposed inside the brush holding case 16 and is rotatably supported by the pivot shaft 15c3 by fitting the pivot shaft 15c3 into the pivot shaft engagement hole 17c. The first arm portion 17a and the second arm portion 17b extend radially around the rotation shaft engagement hole 17c and are formed in a bifurcated shape.

The spring 20 is composed of three types of springs: a rotating brush spring 20a, an arm spring 20b, and a stationary brush spring 20c.

The rotating brush spring 20 a rotates the rotating brush 15, and rotates the rotating brush stand 15 c in the direction in which the cleaning brush 15 a and the discharge brush 15 e are stored in the brush holding case 16 through the recovery brush 18 a side. . That is, the rotating brush 15 is rotated in the direction of the stationary brush 18 by the force of the rotating brush spring 20a, and the impact absorbing member 15f of the rotating brush stand 15c abuts on the rotation suppressing portion 16d provided on the brush holding case 16. The rotation is stopped by In order to suppress the collision sound between the rotating brush stand 15c and the rotation suppressing portion 16d, an impact absorbing member 15f is provided in a portion to be a contact portion of the rotating brush stand 15c to absorb the impact to reduce the collision sound. At the same time, the damage to the component parts is suppressed.

The arm spring 20b presses the arm 17 so that the convex portion 17d of the arm 17 always contacts the convex portion 15c5 of the rotary brush stand 15c unless an external force is applied to the arm spring 20b.

The stationary brush spring 20c presses the stationary brush 18 against the rotating brush base 15c unless an external force is applied to the stationary brush spring 20c.

The dust box 19 is formed of an elongated resin box-like member, and the front surface is opened. A plurality of brush holding case engagement holes 19 a are formed on the left and right sides of the dust box 19. The dust box locking portion 16d is engaged with the engagement hole 19a, whereby the dust box 19 is held by the brush holding case 16.

The side shape of the dust box 19 is substantially triangular so as to substantially coincide with the substantially triangular shape viewed from the side of the space behind the rear heat exchanger portion 9a. With such a configuration, the dust storage amount of the dust box 19 can be increased without increasing the size of the housing 30.

Further, since the dust box 19 is moved along the back of the inclined filter 11, the dust collected from the filter 11 may be dropped from the filter 11 when the dust collected by the filter 11 is cleaned by the cleaning brush 15a. In this case, it can be received by the slide 16f and stored in the dust box 19 as it is.

Next, the operation of the cleaning unit 13 will be described with reference to FIGS. 10A to 10H.

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

In the standby state, the first arm portion 17 a is disposed in the first recess 6 h of the support 6 without being restrained, and the second arm portion 17 b is disposed away from the support 6. Here, the rotary brush 15 is rotated in the direction of the stationary brush 18 because a rotational force is applied in the direction (clockwise direction) of the stationary brush 18 by the rotating brush spring 20a, and the impact absorbing member of the rotary brush stand 15c. 15f is rotated and stopped until the rotation suppressing portion 16d of the brush holding case 16 is abutted. In addition, even after the rotating brush 15 stops rotating, the rotating brush 15 can be kept in the rotating stop state by leaving tension on the rotating brush spring 20 a and applying tension to the rotating brush 15. In the standby state of FIG. 10A, since the cleaning brush 15a does not interfere with other parts, deformation of hair can be minimized.

FIG. 10B is a cross-sectional view showing the 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 retainer 13a, the cleaning unit 13 starts to move in the forward traveling direction of the arrow in FIG. 10B.

When the cleaning portion 13 starts to move, the first arm portion 17a released in the first concave portion 6h comes into contact with the corner portion of the first concave portion 6h, thereby turning the first arm portion 17a counterclockwise. The rotary brush 15 rotates in the counterclockwise direction against the rotational force of the rotary brush spring 20a by the movement of the convex portion 17d of the arm 17 and the convex portion 15c5 of the rotary brush stand 15c. Be moved. Along with the rotation of the rotary brush 15, the cleaning brush 15a and the discharge brush 15e rotate in the direction of the filter 11 (counterclockwise direction) and rise up. Further, with the rotation of the arm 17, the second arm portion 17b also rises and enters the second recess 6i provided in the support 6 adjacent to the first recess 6h.

FIG. 10C is a cross-sectional view showing the cleaning portion 13 in a state where the operation of the cleaning device 5 is further advanced from FIG. 10B.

When the cleaning portion 13 is further moved from FIG. 10B, the second arm portion 17b released in the second recess 6i abuts on the corner portion of the recess 6i, whereby the second arm portion 17b is anticlockwise. It is pivoted in the direction. As a result, the rotary brush 15 is further rotated counterclockwise against the rotational force of the rotary brush spring 20a, and the cleaning brush 15a and the discharge brush 15e are further rotated and raised.

As a result, the cleaning brush 15a rises from the rotating brush stand 15c so as to be at a right angle with respect to the filter 11, so that the filter 11 can be cleaned, and the second arm 17b is the surface of the support 6. The arm contact surface is slid.

In the present embodiment, as described above, the arm 17 is configured by the two stages of the first arm portion 17a and the second arm portion 17b, and rotates like a gear in relation to the adjacent

concave portions

6h and 6i. By doing this, the rotation angle of the arm 17 and the rotating brush 15 can be increased by using the small arm 17 with a good rotation factor with a space factor.

When the cleaning unit 13 is further moved, the front end of the cleaning brush 15a contacts the filter 11 and is deformed in the opposite direction, thereby cleaning the dust collected on the filter 11 and collecting it on the cleaning brush 15a.

In this case, in order to prevent the cleaning brush 15a from rotating more than necessary due to the friction with the filter 11, the cleaning brush 15a is rotated by bringing the rotating brush stand 15c into contact with the rotation suppressing portion 16d at a predetermined position. It is made to suppress. In addition, a play is provided so that the rotation of the cleaning brush 15a can be further rotated from the angle at which the cleaning brush 15a and the filter 11 are perpendicular to each other. The reason is to prevent breakage of the component due to the compressive force and the shear force even when accurate parallel movement is difficult due to distortion or small unevenness of the cleaning device 5 and the filter 11 and the rails 12a and 12b.

When the cleaning brush 15 a moves, dust that has not been collected by the cleaning brush 15 a and has passed through the cleaning brush 15 a may fall from the filter 11. Therefore, in the present embodiment, the slide 16b is provided on the side surface of the brush holding case 16 on the side opposite to the traveling direction, and dust that has passed through the cleaning brush is received by the slide 16f even if it falls from the filter 11. It is guided in the dust box 19.

FIG. 10D is a cross-sectional view showing the cleaning unit 13 in a state where the cleaning unit 13 has moved back and forth from FIG. 10C, and the operation of the cleaning apparatus 5 is further advanced from FIG. It is sectional drawing which shows the cleaning part 13 of a state.

When the cleaning unit 13 reaches the return position, the second arm 17b in contact with the arm contact surface of the support 6 enters the third recess 6j provided at the return position of the support 6, and the other parts Interference is gone and released. As a result, the arm 17 is rotated clockwise by the rotational force of the arm spring 20b, and the rotating brush 15 is rotated clockwise by the rotational force of the rotating brush spring 20a.

By the rotation of the rotary brush 15, the discharge brush 15e is rotated clockwise while rubbing with the recovery brush 18a. Here, since the bristles of the discharge brush 15e and the collection brush 18a face each other and obliquely downward (toward the bottom of the dust box 19), dust collected and attached to the collection brush 18a is the discharge brush 15e. And is discharged into the dust box 19.

Further, due to the rotation of the rotating brush 15, the cleaning brush 15a is rotated while rubbing the recovery brush 18a later than the discharge brush 15e. Here, as shown in FIG. 10D, since the cleaning brush 15a is deformed to the opposite side to the direction of the collection brush 18a, most of the dust attached to the cleaning brush 15a is not passed to the collection brush 18a, It is moved with 15a.

Then, when the cleaning brush 15a passes through the uneven portion 18e of the stationary brush 18, the recessed protrusion 18e functions as a comb, and part of the dust is transferred to the uneven portion 18e, and part of the dust is contained in the dust box 19. It is dropped and the remaining dust adheres to the cleaning brush 15a. Then, the discharge brush 15e and the cleaning brush 15a are further rotated and stored in the brush holding case 16 and the dust box 19, and the shock absorbing member 15f abuts on the rotation suppressing portion 16d to stop the rotation, and the state shown in FIG. It becomes.

10F is a cross-sectional view showing the cleaning portion 13 immediately after the operation of the cleaning device shifts from FIG. 10E to the return path, and FIG. 10G is a cross-sectional view showing the cleaning portion 13 in the state where the operation of the cleaning device further proceeds from FIG. It is.

When the cleaning portion 13 starts to advance in the return path from the state of FIG. 10E, the inclined surface side of the first arm portion 17a abuts on the support 6 as shown in FIG. 10F.

When the cleaning unit 13 further travels in the return path, the support 6 holds the first arm portion 17a against the force of the arm spring 20b that has pressed the convex portion 15c5 of the rotary brush stand 15c and the convex portion 17d of the arm 17. It will be in the pressed state. As a result, as shown in FIG. 10G, the cleaning unit 13 is moved with the cleaning brush 15a and the discharge brush 15e stored in the brush holding case 16 and the dust box 19 in the return path, and returns to the standby state. As described above, by storing the cleaning brush 15a in the brush holding case 16 when advancing the return path so as not to contact the filter 11, the moving direction of the dust becomes one direction, and the sweeping back of the dust can be prevented.

10H is a cross-sectional view showing the cleaning unit 13 immediately after the operation of the cleaning device 5 is started again after the cleaning unit 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 on the uneven portion 18b can be adhered to the rear in the forward traveling direction of the cleaning brush 15a. When the rotating brush 15 is further rotated, the cleaning brush 15a comes in contact with the collection brush 18a again, but when the cleaning brush 15a rotates in the direction of the filter 11 and gets up, it rubs against the reverse direction of the collection brush 18a. The dust adheres to the collection brush 18a, and the filter 11 can be cleaned with the cleaning brush 15a being clean at the next filter cleaning.

Dust attached to the recovery brush 18a is discharged by the discharge brush 15e attached to the rotating brush stand 15c when the rotating brush 15 is rotated in the direction of the dust box 19 as shown in FIG. 10D. It is swept in the direction of the dust box 19. This is due to the rubbing between the discharge brush 15e and the collection brush 18a, but the bristles of the discharge brush 15e are also aligned in the direction of the dust box 19 like the collection brush 18a. Thus, when the rotating brush 15 rises in the direction of the filter 11, it does not affect the dust adhering to the collection brush 18a, but when the rotating brush 15 rotates in the direction of the dust box 19, the discharge brush 15e is reversed. Since it becomes an eye, dust adhering to the recovery brush 18 a can be swept away to the dust box 19.

Although the dust collected in the filter 11 can be transmitted to the dust box 19 by the above series of operations, the cleaning device 5 and the rotating brush can more reliably and efficiently collect the dust in the dust box 19. The cleaning unit 13 has a dust box 19 for storing dust cleaned from the filter 11 by the rotating brush 15. The cleaning unit 13 repeats the short distance reciprocation operation several times after the operation for cleaning the dust collected by the filter 11 The dust attached to the rotating brush 15 is dropped to the dust box 19. Specifically, after one reciprocation of the cleaning unit 13 by filter cleaning, the discharge brush 15e and the collection brush 18a are rubbed together a plurality of times.

Next, a method of disposing of dust accumulated in the dust box 19 by filter cleaning will be described.

The cleaning unit 13 is detachably supported by the support 6, and the cleaning unit main body 37 can be removed from the cleaning device 5 when the dust is discarded. Since the entire cleaning unit main body 37 is integrally detached, it is possible to solve the problem that the dust accumulated in the dust box 19 is scattered.

Then, as shown in FIG. 11, the dust box 19 and the brush holding case 16 are detachable, and by removing the dust box 19 from the brush holding case 16, the dust accumulated in the dust box 19 can be discarded. .

Furthermore, as shown in FIG. 12 and FIG. 13, an opening 19 b is provided on the lower surface of the dust box 19. The opening 19 b is exposed to the air suction port 30 a in a state where the suction 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 unit 13 from the ceiling-embedded air conditioner 1.

When the nozzle 25 is not inserted into the opening 19 b of the dust box 19, the opening is closed by the pivotable cover 24, so the dust in the dust box 9 does not leak from the opening. The cover 24 is pivoted by pushing the cover 24 with the tip of the nozzle 25 so that the tip of the nozzle 25 can be inserted into the opening.

Further, since the guide 25 a is provided in the nozzle 25, the tip of the nozzle 25 can be guided to the opening 19 b of the dust box 19 by using the guide 25 a. By applying the guide 25a to, for example, the decorative panel 3, it is possible to prevent the worker from applying an excessive force and to prevent damage to the components.

According to the present embodiment, when dust is accumulated on the filter 11, the cleaning brush 15a contacts the filter 11 and cleans it in the forward path in which the cleaning unit 13 including the rotating brush 15 moves from one side to the other side I do. At the turning point, the dust collected and attached to the collection brush 18a at the previous filter cleaning is dropped onto the dust box 19 by the discharge brush 15e, and the dust collected at the filter cleaning this time is passed through the discharge brush 15e. By adhering to the collection brush 18a, the filter cleaning operation can be easily performed without human hands. In addition, the filter cleaning function can be mounted without changing the size of the conventional ceiling-embedded air conditioner by housing the filter 11, the cleaning unit 13 and the drive unit 14 inside the housing 2.
