Abstract
A kind of noise reduction air conditioning for automobiles air intake casing, including air intake casing, wherein there are interior circulation air inlet and outer circulation air inlet on air intake casing, described interior circulation air inlet is located at outer circulation air inlet same lateral position and back to driving cabin air inlet forward or positioned at outer circulation air inlet downward vertical position and air inlet mouth down.The interior circulation air inlet of the utility model air intake casing is oriented down or forward, when air-conditioning is in interior circulation pattern, inflow noise will not be propagated directly to driving cabin, and driving cabin can be passed to again by interior follow after the positive fire wall of bad air inlet absorbs major part, so as in the case where not influenceing air inlet air quantity, reduce in-car noise, lifting driving comfort.
Description
Technical field
The utility model category field of automobile air conditioner, the air intake casing being related specifically on air conditioning for automobiles.
Background technology
With the development of auto industry and the improvement of living standards of the people, consumer is to the comfortableness of automobile and health
It is required that increasingly improve, wherein, reducing car noise turns into the subject matter that the needs of raising car steering comfortableness solve.Automobile
Air-conditioning system is the important component of internal car noise, when air conditioning for automobiles normal work, air blower, air flow and other zero
Noise caused by part is directly propagated to in-car, largely effects on the sense of hearing comfort level of in-car, discomfort is brought to occupant.Therefore, it is low
The high performance air conditioning for automobiles of noise is increasingly becoming an important factor for consumer buys automobile.Air conditioning for automobiles air intake casing has two to enter
Gas port, i.e. outer circulation air inlet and interior circulation air inlet.Outer circulation air inlet is and the interior circulation air inlet from car body external feed stream
It is from interior air inlet.The interior circulation air inlet of traditional air intake casing is all directed towards driving cabin, now when air-conditioning is in interior
During circulation pattern, noise caused by the noise and air flow of air blower can be propagated directly to driving cabin, largely effect on driving cabin
Sense of hearing comfort level.
The content of the invention
The purpose of this utility model is the provision of a kind of air intake casing that can effectively reduce noise, and the air intake casing passes through
Bad air inlet direction is followed in change, avoids noise from directly being propagated to in-car while can largely absorb pneumatic noise, so as to effectively
Improve in-car comfortableness.
To achieve the above object, the technical solution of the utility model is：
A kind of noise reduction air conditioning for automobiles air intake casing, including air intake casing 1, wherein there is interior circulation air inlet 3 on air intake casing 1
With outer circulation air inlet 2, it is characterised in that：Described interior circulation air inlet 3 is located at and the same lateral position of outer circulation air inlet 2 and the back of the body
To driving cabin air inlet forward or positioned at the downward vertical position of outer circulation air inlet 2 and air inlet mouth down.
The advantages of the utility model, is as follows：
The interior circulation air inlet of the utility model air intake casing is oriented down or forward, when air-conditioning is in interior cyclic module
During formula, inflow noise will not be propagated directly to driving cabin, and can be followed by interior after the positive fire wall of bad air inlet absorbs major part
Driving cabin is passed to again, so as in the case where not influenceing air inlet air quantity, reduce in-car noise, lifting driving comfort.
Brief description of the drawings
Fig. 1 is the utility model one embodiment structural representation；
Fig. 2 is another example structure schematic diagram of the utility model.
Embodiment
Specific embodiment of the present utility model is further illustrated below in conjunction with the accompanying drawings.
Embodiment one
In Fig. 1：When air conditioning for automobiles is in interior circulation pattern, inlet flap 4 moves to relevant position, by air intake casing 1
Outer circulation air inlet 2 seal, now air-flow will along direction 5 pass through it is interior circulation air inlet 3 enter air-conditioner housing in.Due to this reality
With Novel internal circulation air inlet 3 positioned at the same lateral position of outer circulation air inlet 2 and facing forward back to driving cabin air inlet, now produce
Inflow noise will be absorbed by the interior circulation positive air intake casing 1 of air inlet 3 and be passed to driving cabin after major part again, compare tradition and set
Meter the utility model air intake casing 1 will relatively significantly reduce noise, lift driving cabin comfort level.
Embodiment two
In Fig. 2：When air conditioning for automobiles is in interior circulation pattern, inlet flap 4 moves to relevant position, by air intake casing 1
Outer circulation air inlet 2 seal, now air-flow will along direction 6 from the bottom to top by it is interior circulation air inlet 3 enter air-conditioner housing in.
Because the interior circulation air inlet 3 of the utility model air intake casing 1 is located at the downward vertical position of outer circulation air inlet 2 and air inlet court
Under, and air intake casing has air-conditioner housing further below, now because noise caused by interior circulation air inlet 3 can be absorbed by air-conditioner housing
A part, part is then absorbed by surrounding environment part, when being finally passed in driving cabin, noise that human ear can be experienced have compared with
It is obvious to decline, greatly promote driving cabin comfort level.
