Abstract
The invention discloses a kind of centrifugal blower for air-conditioning equipment air-supply, include housing, the upper end of housing is provided with air inlet, the surrounding of housing bottom is respectively equipped with multiple air outlets, and the lower end of housing is provided with lower air outlet, and the inside of housing is provided with impeller, ventilating opening is provided with the middle part of impeller, the upper end of ventilating opening is corresponding with air inlet, and the lower end of ventilating opening is corresponding with lower air outlet, and the impeller cavity of impeller is corresponding with multiple air outlets respectively.It is big that the present invention solves the space temperature difference caused because blowing range is uneven, the problems such as intermittent difference of air-supply needs manual adjustment, increased the comfortableness of air-supply, air-supply work can be carried out in any tuyere position such as horizontal, vertical, inclination, the wind that air-conditioning is sent out can carry out 360 ° of air-supplies on the direction of former air-supply, increase air-conditioning scope and intermittent air-supply purpose have been reached, it is applied widely, can be widely applied to various forms of air-conditionings.
Description
Technical field
The present invention relates to air-conditioner air supply device field, specifically one kind can increase air-conditioning scope and intermittent use
In the centrifugal blower of air-conditioning equipment air-supply.
Background technology
As air-conditioning equipment application field constantly expands, people and electronic equipment have newly to the air supply mode of air-conditioning equipment
Requirement, and the structure type in air port of blowing determine air-conditioning air-supply quality and cooling effect, the air port master for using at present
If manually or electrically piece-picking type air port, the blowing range in the air port is limited, and wind can only can not meet against a direction blow-through
It is required that.Such as in some driver's cabins and shelter, piece-picking type air port often can not meet the requirement of indoor occupant and instrument, it is necessary to
Increase air channel to reach the purpose integrally lowered the temperature in cabin.
The content of the invention
It is an object of the invention to provide a kind of centrifugal blower for air-conditioning equipment air-supply, make the scope of air-conditioning
It is wider, make the cooling-down effect in regulation space more uniform.
Technical scheme is as follows：
A kind of centrifugal blower for air-conditioning equipment air-supply, includes housing, it is characterised in that：The upper end of the housing sets
The surrounding for having air inlet, housing bottom is respectively equipped with multiple air outlets, and the lower end of housing is provided with lower air outlet, the inside peace of housing
Equipped with impeller, ventilating opening is provided with the middle part of the impeller, the upper end of the ventilating opening is corresponding with described air inlet, ventilating opening
Lower end it is corresponding with described lower air outlet, the impeller cavity of the impeller is corresponding with described multiple air outlets respectively.
The described centrifugal blower for air-conditioning equipment air-supply, it is characterised in that：Described ventilating opening and the leaf
The axis of wheel is concentric.
The described centrifugal blower for air-conditioning equipment air-supply, it is characterised in that：The Leaf positional distribution of the impeller is equal
It is even, and blade has certain thickness so that the impeller cavity formed between blade and blade has noncontinuity.
Operationally, the cold wind that air-conditioning equipment is sent out enters the present invention from air inlet, and a cold wind is by the middle part of impeller
Ventilating opening continues to blow forward, and is transported to by the lower air outlet of housing lower end in the space for needing cooling, and another cold
Wind then enters in the impeller cavity of impeller, original air supply direction is flowed and changed along impeller cavity, by housing bottom four
Multiple air outlets in week are transported in the space for needing cooling, and this part cold wind can produce one instead to make in impeller when leaving
Firmly, so as to promote wheel rotation, 360 ° of purposes of air-supply have been reached, because the impeller cavity formed between blade and blade has
Noncontinuity, so as to reach batch (-type) air-supply purpose.
Ventilating opening is provided with the middle of impeller of the present invention, blowing range is increased, the cold wind of the impeller cavity of impeller is not entered into
Can be blown by the lower air outlet of housing lower end along the ventilating opening of impeller, reach dome-type air-supply, make the scope of air-supply more
It is big, blow it is more uniform.
Beneficial effects of the present invention：
The present invention solves the space temperature difference caused because blowing range is uneven greatly, and the intermittent difference of air-supply needs manual adjustment etc.
Problem, increased the comfortableness of air-supply, can carry out air-supply work in any tuyere position such as horizontal, vertical, inclination, and air-conditioning is sent out
Wind can reach increase air-conditioning scope and intermittent given carrying out 360 ° of air-supplies on the direction of former air-supply
Wind purpose, it is applied widely, can be widely applied to various forms of air-conditionings.
Brief description of the drawings
Fig. 1 is the dimensional structure diagram when present invention is overlooked.
Fig. 2 is the dimensional structure diagram when present invention is looked up.
Specific embodiment
Referring to Fig. 1,2, a kind of centrifugal blower for air-conditioning equipment air-supply includes housing 1, the upper end of housing 1
Air inlet 2 is provided with, the surrounding of the bottom of housing 1 is respectively equipped with multiple air outlets 3, and the lower end of housing 1 is provided with lower air outlet 4, housing 1
Inside impeller 5 is installed, the middle part of impeller 5 is provided with ventilating opening 6, and the upper end of ventilating opening 6 is corresponding with air inlet 2, ventilating opening 6
Lower end it is corresponding with lower air outlet 4, the impeller cavity 7 of impeller 5 is corresponding with multiple air outlets 5 respectively.
In the present invention, ventilating opening 6 is concentric with the axis of impeller 5.
The Leaf positional distribution of impeller 5 is uniform, and blade has certain thickness so that the impeller formed between blade and blade
Chamber 7 has noncontinuity.
Operationally, the cold wind that air-conditioning equipment is sent out enters the present invention from air inlet 2, and a cold wind is by the middle part of impeller 5
Ventilating opening 6 continue to blow forward, and be transported to by the lower air outlet 4 of the lower end of housing 1 in the space for needing cooling, and another
Portion's cold wind then enters in the impeller cavity 7 of impeller 5, is flowed along impeller cavity 7 and is changed original air supply direction, by housing
Multiple air outlets 3 of 1 bottom surrounding are transported in the space for needing cooling, and this part cold wind can be produced when leaving to impeller 5
A raw reaction force, so as to promote impeller 5 to rotate, has reached 360 ° of purposes of air-supply, due to being formed between blade and blade
Impeller cavity 7 have noncontinuity, so as to reached batch (-type) air-supply purpose.
Above example is not limited only to protection scope of the present invention, all to be repaiied based on basic thought of the invention
What is changed or change belongs to protection scope of the present invention.
