The invention discloses a wall-mounted type air-conditioner indoor machine and an air conditioner. The wall-mounted type air-conditioner indoor machine comprises a housing and an air supply assembly, wherein the housing comprises a front housing and a rear housing, wherein the rear end of the front housing is opened, the front housing is in a hollow and semi-spherical shape, and the rear housing is connected with the opening end of the front housing; the air supply assembly is accommodated in the housing; the air supply assembly comprises an air wheel, a driving motor and a support which is used for supporting the air wheel, one end of a rotating shaft of the air wheel is fixedly connected with the driving motor, and the other end of the rotating shaft of the air wheel is rotationally connected with the support. According to the wall-mounted type air-conditioner indoor machine, the support is arranged at one end, away from the driving motor, of the air wheel, the air wheel is rotationally connected with the support, and the two ends of the air wheel are supported by the driving motor and the support respectively, so that the installation stability of the air wheel is improved, the air supply stability of the air wheel is more stable, and accordingly, the phenomenon of wind energy consumption caused by instable air flow is avoided; at the same time, noise caused by collision and friction of the air flow and the front housing and/or the rear housing is reduced, and the noise caused by turbulent flow is eliminated.
