This application claims the priority of Chinese Patent Application No. 201910468299.6 filed on May 31, 2019. The full text of the Chinese patent application is incorporated herein by reference as a part of this application.

Technical field

The embodiment of the present disclosure relates to a volute air outlet reinforcement structure and an air conditioner.

Background technique

For vertical cabinet air-conditioning products, a cross flow fan is usually installed in the indoor unit, and a volute is provided outside the cross flow fan. An air duct is formed between the volute and the cross flow fan. Air inlet and outlet. Generally, the front panel of the vertical cabinet air conditioner is directly hung on the air outlet of the volute. Due to the large area and thick thickness of the front panel, the weight is relatively large. The air outlet is generally made of plastic injection molding, which has limited strength and cannot Long-term stable bearing the weight of the front panel.

In addition, due to the high height and heavy weight of vertical cabinet air conditioners, the volute is generally made of plastic with low hardness and strength. Therefore, the volute is easily deformed during the long-term use of the air conditioner. Among them, especially the air outlet of the volute, due to the large hollow area and lack of strong support, it is extremely easy to deform and affect the normal air outlet.

Therefore, a volute air outlet reinforced structure and an air conditioner are provided to improve the strength of the volute air outlet, especially to increase the connection strength between the volute air outlet and the front panel, and to ensure stable air discharge from the volute air outlet. Technical problems to be solved urgently by those skilled in the field.

Summary of the invention

The embodiments of the present disclosure design a volute air outlet reinforcement structure and an air conditioner to improve the strength of the volute air outlet, especially to increase the connection strength between the volute air outlet and the front panel, and to ensure that the volute air outlet is stable. wind.

In order to solve the above-mentioned problems, the embodiments of the present disclosure disclose a volute air outlet reinforcement structure, which includes a volute and a reinforcing bar. A cross flow fan is arranged in the volute, and a wind is formed between the volute and the cross flow fan. The volute is provided with an air inlet and an air outlet, one side of the air outlet is provided with a connecting plate, and the reinforcing bar is connected with the connecting plate.

By arranging a reinforcing strip on one side of the air outlet, the strength of the air outlet is increased, deformation is prevented, and the stable air outlet of the air outlet is ensured; in addition, the reinforcing strip is installed on one side of the air outlet through a connecting plate. Side, making the installation of the reinforcing strip convenient.
