The first anchor mounting portion 421 is provided to partially face the first tongue 412. One end of the first volute tongue 412 and the first volute 411 enclose a first fan air outlet 413, and the other end thereof is disposed close to the wind wheel 42, especially close to the first anchor mounting portion 421. In the case that the hot and humid air flows through the first volute tongue 412, if the distance between the first volute tongue 412 and the first leg mounting portion 421 is small, the hot and humid air is easily blocked by the first volute tongue 412 and the first leg mounting portion 421, so that the problem that the carried water drops or the driven condensed water remain and easily cause icing is caused. Therefore, by designing the distance between the first volute tongue 412 and the first anchor mounting portion 421 to be greater than or equal to 10mm, the air flow can smoothly flow out of the first fan air outlet 413, and the carried water drops or the driven condensed water is prevented from being blocked to cause icing.

In addition, the distance between the first volute tongue 412 and the wind wheel 42 or the first leg mounting portion 421 is much smaller than the distance between the wind wheel 42 and the first volute 411 and other areas of the first volute tongue 412. Therefore, in the case that the distance between the first volute tongue 412 and the first leg mounting portion 421 is H, the distances between the wind wheel 42 and the first volute 411 and other areas of the first volute tongue 412 are all larger than H, so that smooth flow of the hot and humid air is ensured, and blockage is avoided.

Alternatively, the first anchor mounting portion 421 is located on the air outlet side of the wind wheel 42, and is located on the airflow path of the first fan air outlet 413.

The first anchor mounting portion 421 is located at the air outlet side of the wind wheel 42 and is located on the airflow path of the first fan air outlet 413, so that the distance between the first volute tongue 412 and the first anchor mounting portion 421 is designed to be greater than or equal to 10mm, so that the moist heat airflow can smoothly flow out of the first fan air outlet 413, double obstruction of the moist heat airflow by the first volute tongue 412 and the first anchor mounting portion 421 is avoided, and the moist heat airflow is kept in the volute tongue group value to cause icing.

Note that, the distance between the first anchor mounting portion 421 and the first volute tongue 412 in this embodiment may be understood as the minimum distance between the outer edge of the first anchor mounting portion 421 and the first volute tongue 412.
