Embedded air conditioner internal unit with spiral fan

Abstract

The invention discloses an embedded air conditioner internal unit with a spiral fan. The embedded air conditioner internal unit with the spiral fan is characterized in that a driving motor is arranged in the internal unit main body; a spiral fan and a forward-backward rotation controller are installed on a rotating shaft that is connected to the driving motor; the spiral fan can rotate forwards and backwards to supply air in different directions; the forward-backward rotation controller is synchronized with refrigerating and heating processes and controls the driving motor to rotate forwards and backwards; and the driving motor drives the spiral fan to rotate forwards through the rotating shaft, so that the air-supply direction can be changed. In a refrigeration mode, indoor hot air is pumped into the air conditioner from the center, and cold air is blown out from the periphery; and in a heating mode, the cold air is pumped into the air conditioner from the periphery, and the hot air is blown out from the center. According to the embedded air conditioner internal unit with the spiral fan, the air flow direction in the refrigeration mode and the air flow direction in the heating mode can be controlled separately, so that the heating performance of the embedded air conditioner can be improved greatly; and the problem that the air conditioner has high temperature at the upper part and low temperature at the lower part during a heating process is solved, so that the heating performance is improved.

Description

technical field [0001] The invention relates to an air conditioner inner unit, more specifically, to an embedded air conditioner inner unit with a spiral fan. Background technique [0002] The built-in air conditioners used today discharge the air that has undergone heat exchange from four directions around them, and inhale the air in the room from the central part. This is the case in both cooling and heating modes, where air is sucked in from the center and blown out from the outlets around the sides. Because cold and humid air is denser than hot air, humid air naturally "sinks" and hot air naturally "rises", so the effect is better in cooling mode. In the heating mode, for this reason, after falling for a certain distance, the hot air will be sucked in by the suction force at the central air inlet, resulting in high temperature at the air outlet of the air conditioner and low temperature when it goes down. This phenomenon is very obvious, especially When the area used i...

Problems solved by technology

[0004] In order to solve the above problems, the object of the present invention is to provide a built-in air-conditioning inner unit with a spiral fan, mainly to change the in-out mode of the airflow. In the cooling mode of the air-conditioning inner unit, the indoor cold air is drawn from Inhalation, the hot air is blown out from the surrounding air outlets, while in the heating mode, the cold air in the room is sucked in from the surrounding air outlets and blown out from the central air outlet, this mode changes the airflow in and out mode in the heating mode , towards, thus solving the problem that the built-in indoor unit has poor effect in heating mode, and its air supply volume is not affected
