Abstract
A defrosting air port for an excavator driving cab is characterized in that at least two air outlets are formed on an air duct mounted on a front control box; the air outlets respectively face to an upper piece of glass and a lower piece of glass and can respectively conduct defrosting operations to the upper piece of glass and the lower piece of glass; angles of intersection are formed between the axial directions of the air outlets facing to the upper and the lower pieces of glass and the surfaces of the upper and the lower pieces of glass, so as to ensure that certain angles are formed between the air outlets and the upper and the lower pieces of glass, reduce air-flow resistance and enable air flows to smoothly flow around along the surfaces of the upper and the lower pieces of glass; and shutters which swing horizontally or vertically are arranged on the air outlets. The defrosting air port for the excavator driving cab has the advantages as follows: defrosting control can be conducted to the upper and the lower pieces of glass respectively, the defrosting air port can be opened and closed, the air speed can be controlled at discretion, and the air direction can be adjusted at discretion. The air direction and the air speed can be controlled according to the distributing circumstance of frost and water mist on the upper and the lower pieces of glass, the defrosting efficiency is high, and the use is convenient.
Description
Technical field
The utility model relates to a kind ofly use on construction machinery and equipment, the excavating machine operator's compartment defrosting air port that is particularly suitable for using on excavating machine.
Background technology
At present, the excavating machine operator's compartment of domestic production and use defrosting air port generally has only an air outlet, air-out direction is non-adjustable, and the air outlet that has can't opening and closing, and air-out area is little, windage is big, can't reach good defrosting effect, brings very big inconvenience to the operator.
Summary of the invention
The purpose of this utility model just provides a kind of defrosting efficiency height, excavating machine operator's compartment defrosting air port easy to use.
Solution of the present utility model is such: there are at least two air outlets in the air channel before being installed on the control case, and described air outlet just can carry out defrost operation to upper glass and lower-glass respectively respectively towards operator's compartment fwd upper glass, lower-glass.
Towards the air outlet of upper glass axially be and upper glass face submission horn shape attitude, towards the air outlet of lower-glass axially be and lower-glass face submission horn shape attitude, guarantee that air outlet and glass are angled, reduce air-flow resistance, make air-flow paste the glass face all around swimmingly to flowing.
Air outlet is provided with the louver that swings or swing up and down, and the defrosting air port can open and close, and arbitrarily controlled wind speed size and adjustment wind direction can be controlled wind direction and wind speed according to the situation that frost on glass, water smoke distribute, and improve defrosting efficiency.
The utility model has the advantages that can be respectively to the control that defrosts of last lower-glass, the defrosting air port can open and close, and arbitrarily controlled wind speed size and adjustment wind direction can be controlled wind direction and wind speed according to the situation that frost on glass, water smoke distribute, the defrosting efficiency height, easy to use.
Description of drawings
Accompanying drawing is embodiment of the present utility model.
Accompanying drawing 1 is the utility model front view.
Accompanying drawing 2 is that the A of the utility model accompanying drawing 1 is to view.
The specific embodiment
Each parts list is as follows in the present embodiment:
1, upper glass, 2, lower-glass, 3, air outlet, 4, the air channel, 5, preceding control case.
There are at least two air outlets 3 in air channel 4 before being installed on the control case 5, and described air outlet 3 is respectively towards operator's compartment fwd upper glass 1, lower-glass 2.
Towards the air outlet 3 of upper glass 1 axially is to be the angle of cut state that moves on the wind direction that makes with the upper glass face.
Towards the air outlet 3 of lower-glass 2 axially is to be the angle of cut state that makes motion under the wind direction with the lower-glass face.
Air outlet 3 is provided with the louver that swings or swing up and down.
In the present embodiment, be made up of air outlet 3, air channel 4, preceding control case 5, on the control case 5, preceding control case 5 played a supportive role before air port 3, air channel 4 were assemblied in.Air outlet 3 has two, and respectively facing to upper glass 1, lower-glass 2, and direction forms certain angles with upper glass 1, lower-glass 2 respectively, is convenient to air flows and diffusion.On the air outlet 3 louver is arranged, but the opening and closing air outlet also can 360 degree rotations be regulated air-out direction.Defrosting wind is set out by A/C evaporator, and 4 blow out from air outlet 3 through the air channel, blows on upper glass 1, lower-glass 2, and defrosting wind is pasting the moving diffusion of glass surface current, reaches the purpose of defrosting and water smoke.In the time need defrosting, the direction of two air outlets 3 is all regulated this zone of aligning get final product at certain regional area on glass.
Claims (4)
1. an excavating machine operator's compartment defrosting air port is characterized in that there are at least two air outlets (3) in the air channel (4) that is installed on the preceding control case (5), and described air outlet (3) is respectively towards operator's compartment fwd upper glass (1), lower-glass (2).
2. excavating machine operator's compartment according to claim 1 defrosting air port is characterized in that axially being to be the angle of cut state that moves on the wind direction that makes with the upper glass face towards the air outlet (3) of upper glass (1).
3. excavating machine operator's compartment according to claim 1 defrosting air port is characterized in that axially being to be the angle of cut state that moves wind direction under that makes with the lower-glass face towards the air outlet (3) of lower-glass (2).
4. according to claim 1 or 2 or 3 described excavating machine operator'ies compartment defrosting air ports, it is characterized in that air outlet (3) be provided with axial rotation and can swing louver.
