Abstract

The invention relates to an air conditioner indoor unit, comprising an electric heating device, which is arranged between a heat exchange device and a fan component. The electric heating device comprises a heating crossbeam and a heating frame; the heating frame is arranged at the front side of centrifugal fans and encircles air inlets of the centrifugal fans, the top of the heating frame is connected to the heating crossbeam, and the electric heating device further heats air subjected to heat exchange by the heat exchange device so as to improve a heating effect of the air conditioner indoor unit. The heating frame in the electric heating device forms an encircling ring encircling the air inlets of the centrifugal fans. When the air conditioner indoor unit is in the heating state, the air flowing out from the heat exchange device can make full contact with the electric heating device at the air inlets, such that the heating efficiency of the electric heating device is higher and heat energy is more sufficiently used.

Description

Technical field [0001] The present invention relates to air conditioning technology, in particular to an air conditioner indoor unit. Background technique [0002] Generally, the air conditioner has an electric heating device, or called an auxiliary electric heater or electric auxiliary, which is a component of the air conditioning system. When users use air conditioners for heating in winter, the heating effect of air conditioning units will be greatly attenuated due to the low outdoor temperature. If the working efficiency of the air conditioning heating cycle system is completely relied on, the heating demand cannot be met. In order to better meet the heating needs of users, auxiliary heaters need to be supplemented on the basis of central air conditioning units. The auxiliary heater can be used independently or simultaneously with the heating cycle system. Connect the auxiliary heater to the air path of the air conditioner. When heating in winter, the air is heated by the a...
