  • the assist roller 70 is divided into two parts in the vicinity of the two sides 16b and 16c of one air filter 16.
  • the number of assist rollers 70 is not limited to two, and may be divided into three or more, or may be configured by a single roller that pushes the entire air filter 16.
  • (5-2) Modification 1B In the above embodiment, when the air filter 16 and the drive roller 54 are attached to and detached from the air conditioning indoor unit 10, the filter assembly 52 is attached to and detached from the support frame 51. However, the air filter 16 and the drive roller 54 need not be assembled and attached in the state of the filter assembly 52, and the air filter 16 and the drive roller 54 are individually attached to and detached from the air conditioning indoor unit 10. It can also be configured.

Abstract

L'invention concerne un appareil intérieur de conditionnement d'air dans lequel le nettoyage est effectué par déplacement d'un filtre, et plus précisément, la miniaturisation d'un mécanisme de déplacement de filtre destiné à l'entraînement du filtre. Ce mécanisme de déplacement de filtre (50) qui déplace un filtre à air (16) dans le cadre d'un nettoyage automatique, est équipé d'un rouleau d'entraînement (54) et de rouleaux auxiliaires (70). Ces rouleaux auxiliaires (70) sont disposés de manière à enserrer le filtre à air (16) et à faire face au rouleau d'entraînement (54), et pressent le filtre à air (16) sur le rouleau d'entraînement (54). Le rouleau d'entraînement (54) déplace le filtre à air (16) de sorte qu'il ne glisse pas, par rotation dans un état dans lequel le filtre à air (16) est enserré entre les rouleaux auxiliaires (70).
