Description

A ceiling-mounted air conditioner indoor unit

technical field

The utility model relates to the technical field of air conditioner indoor units, in particular to a ceiling-mounted air conditioner indoor unit.

Background technique

In the prior art, in the air-conditioning system, most of the ceiling-mounted indoor units adopt the air supply mode in which the air is returned from the middle and the air is released from the outer ring. In this air supply mode, the air sent by the indoor unit has a low wind speed from the outer curve, so that the hot air sent by the indoor unit cannot be effectively delivered to the indoor personnel activity area during the heating process, resulting in heating. In this mode, the user's somatosensory comfort is poor.

Utility model content

The technical problem to be solved by the utility model is to provide a ceiling-mounted indoor unit that can effectively deliver hot air to the indoor personnel activity area in the heating mode.

The technical scheme of the utility model is to provide a ceiling-mounted indoor unit with the following structure, including a housing provided with a housing cavity, a motor and a heat exchanger are installed in the housing cavity, and the heat exchanger will accommodate The cavity is divided into a return air slot and an air outlet slot. A water receiving tray is installed under the heat exchanger, and an outlet grille is installed under the water receiving tray to seal the notch of the air outlet slot. An axial flow fan is installed on the output shaft of the motor, and there is a gap between the axial flow fan and the outlet grille.

The beneficial effect of the technical solution of the utility model is: by replacing the original fan on the indoor unit with an axial flow fan, the axial flow fan completely changes the wind direction of the entire indoor unit, and becomes the middle air supply and the outer ring return air, which is more effective in heating. The hot air can be sent to the indoor personnel in time, which meets the comfort of heating.

Further, the inner side of the water tray is provided with an annular fan guide ring for guiding the air flow out, and the fan guide ring is arranged around the axial flow fan.

Further, a fan guide vane is provided at an end of the fan guide ring close to the axial fan, and the extension direction of the fan guide vane is parallel to the axis of the rotating shaft of the axial fan.

Further, an end of the fan deflector away from the outlet grill is inclined in a direction away from the axial fan.

Further, an electric heater electrically connected to the motor is also arranged in the return air slot.

Further, the electric heater is arranged around the motor.

Further, return air vanes are provided at the lower openings of the air outlet slots.

Further, a panel is provided at the lower opening of the housing.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

Please refer to Fig. 1 and Fig. 2, the utility model provides a ceiling-mounted air-conditioning indoor unit, which includes a housing 2 provided with an accommodating cavity 1, a motor 3 and a heat exchanger 4 are installed in the accommodating cavity 1, The heat exchanger 4 divides the chamber 1 into a return air slot 1a and an air outlet slot 1b. A water receiving tray 5 is installed under the heat exchanger 4, and a notch for sealing the air outlet slot 1b is installed under the water receiving tray 5. The outlet grille 6, the output shaft of the motor 3 is equipped with an axial fan 7, leaving a gap between the axial fan 7 and the outlet grille 6.

Specifically, as shown in FIG. 1 , it is a structural diagram of a ceiling-mounted indoor unit in the prior art. Since many components of the indoor unit in this application are the same, the same components are given the same reference numerals in FIG. 1 . It is easy to know that the ceiling-mounted indoor unit also includes other components, but since the improvement of the indoor unit in this application mainly lies in the axial flow fan, other known structures will not be repeated here. In this embodiment, as shown in Figure 2, by replacing the original fan on the indoor unit with an axial flow fan 7, the axial flow fan 7 completely changes the wind direction of the entire indoor unit to become the middle air supply and the outer ring return air. During heating, the hot air can be sent to the indoor personnel in time, which meets the comfort of heating.

In one of the implementation manners, the inner side of the water receiving tray 5 is provided with an annular fan guide ring 8 for guiding the air flow out, and the fan guide ring 8 is arranged around the axial flow fan 7 .
