Embodiment Construction

[0026] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0027] Such as Figure 1 to Figure 4 As shown, the present invention provides a fan 10, which is arranged on electrical equipment. The fan 10 includes: a volute 11, a volute tongue 12 and a fan blade 13. The volute 11 and the volute tongue 12 together form at least Part of the accommodation cavity 14 and the first tuyere 15 communicating with the accommodation cavity 14, the first tuyere 15 is located on the side of the accommodation cavity 14 close to the interior of the electrical equipment; , so as to adjust the gap between the cochlear throat introduction section 20 and the vane 13 by controlling the movement of the cochlear throat introduction section 20 and guide the airflow at the first...

Abstract

The invention provides a draught fan and an air conditioner with the same, the draught fan is arranged on electrical equipment, the draught fan comprises a volute, a volute tongue and fan blades, the volute and the volute tongue jointly define a containing cavity used for containing at least part of the fan blades and a first air opening communicated with the containing cavity, and the first air opening is located in the side, close to the interior of the electrical equipment, of the containing cavity; and the volute throat leading-in section is movably arranged at the first air opening, so that the clearance between the volute throat leading-in section and the fan blades is adjusted by controlling the movement of the volute throat leading-in section, and the airflow at the first air opening is guided. According to the fan, the problem that in the prior art, the air inlet amount of a fan is small is solved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a fan and an air conditioner with the same. Background technique [0002] The existing wall-mounted air-conditioning internal unit often has only one fan, which has limited air supply range and effect, and the air intake volume of the fan is limited, which cannot meet people's increasingly diverse living needs. [0003] In this regard, someone proposed an air conditioner including an upper fan and a lower fan. This air conditioner not only has a wide range of air output, but also can selectively turn on the air supply mode of the upper fan or the air supply mode of the lower fan according to the needs of users. Wind patterns are diverse. [0004] However, limited by the air intake area of ​​the fan, it is difficult to greatly improve the performance of the air conditioner with the upper and lower air outlets. Contents of the invention [0005] The main purpose of the...
