And a light emitting element 231.

  The inner housing 211 is hollow and cylindrical, but has a bottom and a top. The central post 213 is located at the central portion of the inner housing 211.

  A hole is formed in the bottom of the inner housing 211. The first pipe 217 and the second pipe 219 are connected to the mixer 221 in the inner housing 211 through the holes in the bottom surface. The first pipe 217 and the second pipe 219 are connected to the cleaning container or the like in the main body 400, and the cleaning container and the mixer 221 are connected by the first pipe 217 and the second pipe 219.

  The first pipe 217 and the second pipe 219 may be provided so as to pass through the inside of the connection arm 300 between the injector 200 and the main body 400, and are provided along the connection arm 300.

The components mixed in the mixer 221 are sent to the nozzle arrangement 225 through the injection pipe 223.

  The motor 215 supports the bottom of the inner housing 211. As the motor shaft moves up and down, the mixer 221, the injection pipe 223 connected to the mixer 221, the nozzle arrangement portion 225 and the central column 213 move up and down together with the inner housing 211. Therefore, the nozzle 227 can be moved up and down at the time of cleaning, and as a result, the efficiency of the cleaning can be improved.

  The outer housing 214 is formed to include the inner housing 211, the motor 215, the first pipe 217 and the second pipe 219 therein.

  The nozzle placement portion 225 is located above the inner housing 211. In the nozzle arrangement portion 225, a large number of nozzles 227 are mounted and arranged. The outer surface of the nozzle placement portion 225 is composed of a large number of surfaces 225a to 225d having different slopes from each other, and has an almost hemispherical shape as a whole. Here, an example in which the outer surface of the nozzle placement portion 225 is configured by the first to fourth surfaces 225a to 225d will be described.

  The first to fourth surfaces 225a to 225d are different from one another and have constant slopes, respectively, and are provided around the center post 213 over a round.

  The first surface 225a is a surface having a first gradient α1 (= 0 °) with respect to the horizontal plane. That is, the first surface 225a is a horizontal surface. The second surface 225 b is connected to the first surface 225 a and is a surface of a second gradient α2 (> α1) larger than the first gradient α1. The third surface 225c is connected to the second surface 225b, and is a surface of a third gradient α3 (> α2) larger than the second gradient α2. The fourth surface 225 d is connected to the third surface 225 c and is a surface of a fourth gradient α4 (> α3) larger than the third gradient α3. The fourth gradient α4 is approximately 90 °.

  A plurality of nozzles 227 are mounted on the first to third surfaces 225a to 225c, respectively. Further, the fourth surface 225 d is provided with a plurality of injection holes 233. The component that has passed through the mixer 221 is sent to the nozzle arrangement portion 225 through the injection pipe 223, and is injected from the nozzle 227 and the injection hole 233.

  The plurality of nozzles 227 are provided in the direction orthogonal to each of the mounted first to third surfaces 225a to 225c, and jets the component that has passed through the mixer 221 in this direction.

  The outer surface of the nozzle arrangement portion 225 is constituted by a large number of surfaces 225a to 225d having different gradients from each other, so the direction of ejection from the nozzle 227 and the injection hole 233 is from the vertical direction to the horizontal direction In various directions. As a result, a wide area can be cleaned at one time.

  Although the outer surface of the nozzle arrangement | positioning part 225 demonstrated the example comprised by the several surface connected with a different gradient here, it is not limited to this. The outer surface of the nozzle placement portion 225 may be a dome-shaped curved surface such as a hemispherical surface. In this case, the nozzles 227 may be arranged such that there are sets of nozzles having different injection angles with respect to the vertical line.

  The injection holes 233 are provided on the fourth surface 225 d along the circumferential direction. The injection holes 233 are provided in the circumferential direction of a circle centered on the central column 213 in the horizontal plane, and inject the component that has passed through the mixer 221 in this direction.

  Here, since the plurality of injection holes 233 are provided in the same circumferential direction, the injector 200 is rotated by the injection operation of the plurality of injection holes 233. Here, an example in which the injector 200 is rotated by the injection from the injection hole 233 has been described, but the injector 200 may be rotated using a motor.

  At least one light emitting element 231 is disposed around the image acquisition unit 229. At the time of cleaning, since the water collector 100 is in contact with the indoor unit of the air conditioner, the inside of the water collector 100 may be dark and it may be difficult to read the acquired image by the image acquisition unit 229. Therefore, the illumination of the light emitting element 231 is used to obtain an image.

  Here, although the example in which the mixer 221 is provided in the injector 200 has been described, it is not limited thereto. The mixer 221 may be provided in the main body 400. In this case, instead of the first pipe and the second pipe, the injection pipe 223 may be provided to pass through the inside of the connection arm 300 or may be provided along the connection arm 300. In this case, the nozzle placement unit 225 is moved up and down by the motor 215.

  Since the water collector 100 is made of a flexible material, it is necessary to fix the shape by the support structure, for example, when it is used.
