Abstract
The utility model provides a cabinet volute. The problem that an existing cabinet volute is provided with a guiding plate for air flow stall and easily produces air flow noise can be solved. The arc-shaped guiding plate is arranged at the position of an air flow outlet of the cabinet volute, the guiding plate is located on a base plate of the volute, and guiding through holes are distributed in the guiding plate. The guiding through holes are added in the guiding plate in the volute, so that eddy at the position of a guiding plate outer plate is carried outward through air flows at the position of the inner plate face and the guiding through holes and can be absorbed and dissipated, and accordingly the air flow noise is reduced. In the same way, the guiding through holes can further absorb and dissipate other refraction sound waves at the position, sound wave superposition is prevented, the noise-reducing purpose is achieved, and the whole machine performance is optimized.
Description
Technical field
The utility model relates to the structure member of air-conditioner, is specifically related to a kind of cabinet-type air conditioner spiral case that can prevent air-flow stall, reduce noise.
Background technology
Cabinet-type air conditioner centrifugal fan is after motor drives, under the effect of spiral case, recover static pressure, because spiral case blower fan top is large to this section of regional gas stream VELOCITY DIFFUSION angle of air outlet, cause pressure to increase fast, part air velocity is unbalance, the speed in this region and circumferential velocity are obviously inconsistent, cause air-flow to have some setbacks, easily form eddy current, be called air-flow stall, air-flow stall meeting make cabinet-type air conditioner spiral case around send " z z z " wheeze or other more ear-piercing sound, be called different sound, different sound is different from general noise, it is more ear-piercing, human body can not be accepted, cause user discontented, numerous and confused complaint complained.
For addressing the above problem, normally set up arc deflector at spiral case air outlet place, deflector is connected on spiral case base plate and along air-flow air-out direction and extends, and between its front end and air-flow air-out direction, forms zero-incidence.Can prevent air-flow stall by deflector is set, eliminate different sound.But because air deflector is in spiral case air outlet place, wind speed is higher herein, deflector is set and makes airflow diversion, the large (crushing Pt=a × V of crushing
bwherein a, b are that constant and a, b are all greater than 0, V is windward side speed, so near deflector, the large crushing of wind speed is also high), easily produce sound wave stack at the outer plate surface place of deflector, form eddy current, produce pneumatic noise, although arrange that deflector has been eliminated different sound but the pneumatic noise of its generation can not be ignored, affect cabinet-type air conditioner overall performance.
Utility model content
The utility model provides a kind of cabinet-type air conditioner spiral case and cabinet air-conditioner, can solve existing cabinet-type air conditioner spiral case and deflector is set prevents that air-flow stall from easily producing the problem of pneumatic noise.
For reaching the object solving the problems of the technologies described above, the cabinet-type air conditioner spiral case that the utility model proposes is achieved by the following technical solutions: a kind of cabinet-type air conditioner spiral case, the air-flow air outlet place of described spiral case is provided with the deflector of arc, described deflector is positioned on the base plate of described spiral case, is laid with water conservancy diversion through hole on described deflector.
In the technical solution of the utility model, also comprise following additional technical feature: the percent opening of described water conservancy diversion through hole is 20～80%.
The aperture of described water conservancy diversion through hole is 5～18mm.
Described water conservancy diversion through hole is uniformly distributed.
Described water conservancy diversion through hole is straight hole or inclined hole.
Arc transition between the two ends of described water conservancy diversion through hole and described deflector.
The utility model has also proposed a kind of cabinet air-conditioner, and above-mentioned cabinet-type air conditioner spiral case is installed.
Compared with prior art, the utility model by setting up water conservancy diversion through hole on the inner arc deflector of spiral case, the eddy current that makes deflector outer plate surface place is taken out of (taking the inner concave of deflector as its inner plate surface through water conservancy diversion through hole by the air-flow at its inner plate surface place, relative another side is outer plate surface), can inhale loose deflector eddy current herein, thereby reduce pneumatic noise, in like manner water conservancy diversion through hole can also absorb dissipation other refraction sound wave herein, prevent sound wave stack, reach noise reduction object, optimized overall performance.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment cabinet-type air conditioner spiral case;
Fig. 2 is the structural representation of deflector in the utility model embodiment.
Detailed description of the invention
For making object, technical scheme and the advantage of the utility model embodiment clearer, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
See figures.1.and.2, the present embodiment cabinet-type air conditioner spiral case 1, the air-flow air outlet 1.3 that spiral case 1 has the side plate 1.2 of base plate 1.1, base plate 1.1 both sides and surrounded by the side plate 1.2 of base plate 1.1, both sides, air-flow air outlet 1.3 places are provided with the deflector 2 of arc in case locate here air-flow stall, deflector 2 is positioned on base plate 1.1, is laid with water conservancy diversion through hole 2.1 on deflector 2.
The number of water conservancy diversion through hole 2.1 is according to the different operating modes of spiral case 1 and difference, and in general, its percent opening scope is 20～80%, and concrete numerical value determine according to concrete operating mode, and by evidence, percent opening is advisable with 50%, inhales the best results of loose eddy current, absorption sound wave; Described percent opening is the ratio of single lateral plates (being a plate face in its inside and outside plate face) area of the gross area and the deflector 2 of all water conservancy diversion through holes 2.1 on deflector 2.
The aperture d of water conservancy diversion through hole 2.1 is advisable with 5～18mm, and the concrete operating mode of same basis is determined.
Water conservancy diversion through hole 2.1 can be uniformly distributed or irregular distribution, to be uniformly distributed as optimum arrangement mode.
Water conservancy diversion through hole 2.1 is specially straight hole or inclined hole is unrestricted, can be one-body molded with deflector 2.
Windage when water conservancy diversion through hole 2.1 is taken away eddy current while faling apart for reducing eddy current suction, adopts arc transition between the two ends of water conservancy diversion through hole 2.1 and deflector 2.
