  • the third connection wire 213 passes from the side of the pressing plate 111 away from the first mounting portion 1104 (refer to the right side of the pressing plate 111 shown in FIG. 6 ), and passes from the side of the pressing plate 111 close to the second mounting cavity 212 (refer to FIG. 6 )
  • the front of the shown pressing plate 111 enters the second installation cavity 212 to be electrically connected with the connection terminal 230 , so that it is convenient to reduce the wiring distance from the third connection wire 213 to the second installation cavity 212 .
  • the pressing plate 111 has lead passages 1114 for guiding the third connection wires 213 to the second mounting cavity 212 .
  • the pressing plate 111 includes a base plate 1111 , a third side plate 1112 and a fourth side plate 1113 .
  • the base plate 1111 is connected to the first mounting portion 1104
  • the third side plate 1112 and the fourth side plate 1113 are respectively connected to the base plate 1111 and located on the same side of the base plate 1111 .
  • the base plate 1111 , the third side plate 1112 and the fourth side plate 1113 configure the lead channel 1114 .
  • the third connecting wire 213 is guided into the second mounting cavity 212 through the lead channel 1114 .
  • the substrate 1111 is configured to separate the third connection lines 213 from the first connection lines 320 and the second connection lines 530, respectively.
  • the third side plate 1112 is configured to separate the third connection wire 213 and the power wire 214 .
  • the fourth side plate 1113 is located between the third connection wire 213 and the driving motor 500 and is configured to separate the third connection wire 213 from the driving motor 500 .
  • both the third side plate 1112 and the fourth side plate 1113 are located on the side of the base plate 1111 away from the first mounting portion 1104 .
  • the third connection line 213 and the power line 214 are located on both sides of the third side plate 1112 , respectively.
  • the third connecting wire 213 and the driving motor 500 are located on both sides of the fourth side plate 1113 respectively.
  • the pressure plate 111 further includes a folding ear 1115 .
  • the folding ears 1115 are connected to the third side plate 1112 .
  • the folding ears 1115 are perpendicular to the third side plate 1112 and extend away from the lead channel 1114 .
  • the folding ears 1115 are configured to limit the position of the power cord 214 .
  • the folding ears 1115 can be formed by bending a part of the third side plate 1112 .
  • the platen 111 is configured to partially surround the third connection wire 213 to form the lead channel 1114 .
  • the wiring distance from the third connection wire 213 to the second installation cavity 212 can be shortened, and excessive bending of the third connection wire 213 can be avoided, which is convenient for installation by the installer.
  • the third connecting wire 213 and the power wire 214 pass through the air conditioner indoor unit 10 from the base 110, the distance between the third connecting wire 213 and the power wire 214 is relatively small. Therefore, the power line 214 and the third connection line 213 are separated by the third side plate 1112 to prevent the third connection line 213 and the power line 214 from being entangled. In addition, the third side plate 1112 can also guide the wiring of the power cable 214 , so as to guide the power cable 214 into the first installation cavity 211 .

Abstract

La présente invention concerne une unité intérieure de climatiseur (10), comprenant une base (110), un composant de passage d'air (100), un échangeur de chaleur intérieur (400), un ventilateur intérieur (600), un ensemble de commande électrique (200), un écran d'affichage (300) et un couvercle externe (700), le composant de passage d'air (100) étant raccordé à la base (110) et étant pourvu d'une sortie d'air (101); l'échangeur de chaleur intérieur (400) est raccordé à la base (110); une partie du ventilateur intérieur (600) est positionnée dans le composant de passage d'air (100); l'ensemble de commande électrique (200) est raccordé à la base (110); l'écran d'affichage (300) est raccordé à la base (110) et est raccordé électriquement à l'ensemble de commande électrique (200) au moyen d'une première ligne de raccordement (320); et le couvercle externe (700) est raccordé de manière amovible à la base (110) et comprend une zone d'affichage correspondant à l'écran d'affichage (300). La présente invention concerne en outre un climatiseur (1000) comprenant l'unité intérieure de climatiseur (10). Les problèmes de non-raccordement et de raccordement incorrect liés au besoin d'avoir à raccorder de nouveau une ligne de raccordement peuvent être évités, et le démontage et le montage sont pratiques.
