Problems solved by technology

[0002] Portable air conditioners are easy to install and use, and are more popular in European and American markets. However, as a member of integral air conditioners, the same noise problem has seriously affected the comfort of mobile air conditioners. Only the development of lower noise mobile air conditioners can improve product competitiveness.
The outer air duct of the current mobile air conditioner is composed of two parts, namely the volute cover and the volute seat. Half of the inner cavity of the existing outer air duct is on the volute cover, and the other half is on the volute seat, and the volute tongues are made of The inner air duct smoothly transitions to the outer air duct, which is prone to vortex wind phenomenon, and the angle of the volute tongue does not match the angle of the wind rotor blade, which generates high noise and affects the user experience

no. 1 example

[0035] Please refer to figure 1 , the embodiment of the present invention provides a fan structure 1 for blowing airflow to the outside. Its structure is simple, the size parameters of each component are allocated reasonably, the vortex phenomenon is avoided, and the generated noise can be effectively reduced, noise pollution is avoided, and the utility model has strong practicability. In this embodiment, the fan structure 1 is applied in the air conditioner. When the air conditioner is started, the fan structure 1 works to blow out the hot air or cold air generated by the heat exchange in the air conditioner into the room to regulate the indoor temperature.

[0036] The fan structure 1 includes a volute seat 2 , a volute cover 3 and a centrifugal fan 4 . The volute seat 2 is detachably connected with the volute cover 3 along the axial direction of the volute seat 2. In this embodiment, both the volute seat 2 and the volute cover 3 are disc-shaped. During the installation pro...

[0050] An embodiment of the present invention provides an air conditioner (not shown in the figure), which is used for regulating indoor air temperature. The air conditioner includes a casing (not shown) and a fan structure 1 . Among them, the basic structure, principle and technical effect of the fan structure 1 are the same as those of the first embodiment. For a brief description, for parts not mentioned in this embodiment, reference may be made to the corresponding content in the first embodiment.

[0051] In this embodiment, the fan structure 1 is installed in the casing, and the casing can protect the fan structure 1, and the fan structure 1 is used to output airflow to blow out hot air or cold air generated by heat exchange into the room.

[0052] The beneficial effect of the air conditioner described in the embodiment of the present invention is the same as that of the first embodiment, and will not be repeated here.

Abstract

The invention provides a draught fan structure and an air-conditioner, and relates to the technical field of air-conditioners. The draught fan structure comprises a volute base and a volute cover. Thevolute base is detachably connected with the volute cover in the axis direction of the volute base, the volute cover is provided with a first cavity and a first volute tongue located in the first cavity, and the volute base is provided with a second cavity and a second volute tongue located in the second cavity, the first cavity and the second cavity are combined into an air passage, and the first volute tongue abuts against the second volute tongue. Compared with the prior art, the draught fan structure adopts the first cavity with the specific value range of 1 / 2-8 / 9 and the first volute tongue with the included angle range of 2-5 degrees, size parameters of the volute base and the volute cover are reasonably allocated, the vortex wind phenomenon is avoided, the generated noise can be effectively reduced, the noise pollution is avoided, and the practicability is high.
