Abstract
本实用新型涉及一种盘管风机，特别是涉及一种盘管风机中蜗壳的改良结构。该盘管风机，由蜗壳及其内的叶轮组装构成，其中蜗壳的风口处设置加强筋，该加强筋向蜗壳本体外侧凸出。该加强筋是把盘管风机中蜗壳向内凸的加强筋改成向外凸，相比于原先的盘管风机，该盘管风机气流经过时顺畅且没有阻力，噪音大大降低，风速也得以提高，从而也提高整个风机的质量和性能。
The utility model relates to a coil fan, and more particularly to an improved structure of a volute in a coil fan. The coil fan is composed of a volute and an impeller therein, wherein a reinforcing rib is arranged at the air outlet of the volute, and the reinforcing rib protrudes toward the outside of the volute body. The reinforcing rib is a reinforcing rib that is convex inwardly in the volute of the coil fan and is convex outwardly. Compared with the original coil fan, the airflow of the coil fan is smooth and without resistance, the noise is greatly reduced, and the wind speed is also increased, thereby improving the quality and performance of the entire fan.

本实用新型涉及一种盘管风机，特别是涉及一种盘管风机中蜗壳的改良结构。The utility model relates to a coil fan, in particular to an improved structure of a volute in the coil fan.
背景技术Background technique
盘管风机是由蜗壳和叶轮组合而成。风机的性能优劣主要取决于噪音、功率、风量。目前风机厂家为了加强风机蜗壳的强度，在风口处设置加强筋，加强筋均向蜗壳本体内侧凸出。这样的结果使得加强筋的强度虽然有所加强，但出风口的风速很高，凸起的台阶使气流经过时受到一个突然的阻力，导致气流向上跳起从而引发噪音增高，风速下降，进而影响到了整个风机的质量和性能。The coil fan is composed of a volute and an impeller. The performance of the fan mainly depends on the noise, power and air volume. At present, in order to strengthen the strength of the fan volute, fan manufacturers have provided reinforcing ribs at the tuyere, and the reinforcing ribs all protrude toward the inner side of the volute body. As a result, although the strength of the ribs has been strengthened, the wind speed at the air outlet is very high, and the raised steps make the air flow encounter a sudden resistance when it passes by, causing the air flow to jump upwards, resulting in increased noise and a decrease in wind speed, which in turn affects To the quality and performance of the entire fan.
实用新型内容Utility model content
为了克服现有的加强筋导致风机性能减弱的不足，本实用新型提供了一种盘管风机蜗壳中加结构改良的加强筋。In order to overcome the deficiency that the performance of the fan is weakened by the existing reinforcing ribs, the utility model provides a structurally improved reinforcing rib added to the volute of the coil fan.
本实用新型解决其技术问题所采用的技术方案是：一种盘管风机，由蜗壳及其内的叶轮组装构成，其中蜗壳的风口处设置加强筋，所述的加强筋向蜗壳本体外侧凸出。The technical scheme adopted by the utility model to solve the technical problem is: a coil fan, which is composed of a volute and an impeller inside, wherein a reinforcing rib is arranged at the tuyere of the volute, and the reinforcing rib is directed towards the volute body. Protruding outside.
优选地，所述的加强筋设置在蜗壳的上风口处。Preferably, the reinforcing rib is arranged at the upper air outlet of the volute.
本实用新型的有益效果是：把盘管风机中蜗壳向内凸的加强筋改成向外凸，相比于原先的盘管风机，该盘管风机气流经过时顺畅且没有阻力，噪音大大降低，风速也得以提高，从而也提高整个风机的质量和性能。The beneficial effect of the utility model is that: the reinforcing rib of the volute in the coil fan is changed to protrude outward. Compared with the original coil fan, the air flow of the coil fan passes smoothly and has no resistance, and the noise is large. Reduced, the wind speed can also be increased, thereby also improving the quality and performance of the entire fan.
