Problems solved by technology

Chinese patent CN109764407A discloses that the airflow concentration of the mixed-flow fan outlet of the air-conditioning ventilation part is high, and the airflow cannot be fully diffused to all areas of the room, and the airflow blind area is large. Some patents and products lead the airflow into the main mixed-flow fan. This method leads to The fresh air flow is polluted twice by the environment inside the machine, and the airflow is bent at the same time, resulting in low efficiency

Embodiment 1

[0036] The fresh air duct structure disclosed in this embodiment, Figure 1-Figure 3 As shown, the air duct pipe 1 is included, the air duct pipe 1 is installed in the air conditioner housing 2, the air duct pipe 1 extends along a straight line, and the air duct pipe 1 is provided with a mixed flow fan 3 and a purification module 4. The exhaust end of the mixed flow fan 3 points straight to the air outlet 5 of the air duct pipe 1, the air inlet end of the mixed flow fan 3 points straight to the air inlet 6 of the air duct pipe 1, and the purification module 4 blocks the The air inlet 6 or the air outlet 5 of the air duct 1 is aligned with the air inlet 6 and the air outlet 5 .

[0037] In the above-mentioned fresh air duct structure, the duct pipe 1 extends along a straight line, so that the air intake mode is a straight air intake mode, and there is no elbow structure in the air intake path to reduce the air intake resistance. The mixed-flow fan 3 is used to overcome the air...

Abstract

The invention relates to the technical field of air conditioners, in particular to a fresh air duct structure and a fresh air wall-mounted machine, the fresh air duct structure comprises an air duct pipe, the air duct pipe is installed in an air conditioner shell, the air duct pipe extends along a straight line, and a mixed flow fan and a purification module are arranged in the air duct pipe; the air exhaust end of the mixed flow fan linearly points to the air outlet of the air duct pipe, the air inlet end of the mixed flow fan linearly points to the air inlet of the air duct pipe, and the purification module blocks the air inlet or the air outlet of the air duct pipe and is aligned to the air inlet and the air outlet. The fresh air duct structure has the advantages of being high in air outlet efficiency, large in air volume and high in purification efficiency.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a fresh air duct structure and a fresh air wall hanging machine. Background technique [0002] The mixed-flow fan has strong load resistance and is suitable for occasions with high pipe network resistance. When the pipe network resistance is low, it usually cannot reflect the superior performance of the mixed-flow fan. For example, when the mixed flow fan is applied to the main air duct of the air conditioner, since the air inlet resistance of the heat exchanger is usually only 20-25Pa, plus the resistance of the air inlet and outlet pipes, the overall resistance is usually 30-40Pa, and the resistance of the pipe network is less than the load resistance of the mixed flow fan. capacity, resulting in loud noise of the mixed flow fan. [0003] The resistance (50-100Pa) of the purification module of the ventilation part of the fresh air wall-mounted machine is higher than t...
