Consider the less feature of air-conditioner outdoor unit footing area, the area of contact of itself and lower wrapped pad is very little, and when transportation or bottom surface are impacted, footing the most easily deforms, lower wrapped pad also can, in the even fracture of position distortion contacting with footing, cause complete machine to tilt easily to topple over.
Existingly can take the measure of remedying to be, for heavier air-conditioner outdoor unit, greater impact and distortion that its wrapped pad is often used the material of density higher (foam expansion is lower) may occur with reply, but when the impulsive force of base plate is larger, be easy to cause bottom deformation, also wasted material simultaneously, improved productive costs.
In view of this, the special present patent application that proposes.
Summary of the invention
Lower packaging cushion for air-conditioning outdoor machine of the present invention, its object is to solve problem that above-mentioned prior art exists and for selected polystyrene foamed (EPS) or polyethylene foamed (EPE) material, reasonably adjust the pad height in electric machine support on corresponding support baseboard, compressor region, under not increasing under the prerequisite of the whole usable height of wrapped pad, the harmony of rear lower wrapped pad whole height is out of shape in raising, thereby avoids the generation of footing distortion and complete machine tilt problem.
For achieving the above object, described lower packaging cushion for air-conditioning outdoor machine mainly includes:
By functional regional division, include the A2 portion that supports compressor on the A1 portion of electric machine support on the B portion of unsplit bed(-)plate, the E portion that supports side feet and corresponding support baseboard, corresponding support baseboard.
Wherein, the vertical height of B portion is H.Difference with the prior art part is, the vertical height of described A2 portion is H+ δ 2, δ 2=(PA2/P) * ε * t;
Wherein, PA2 is the stress value that compressor acts on A2 portion surface, and unit is Kpa;
P is the compressing stress of the corresponding density of the selected material of wrapped pad;
ε is the percent strain of the corresponding density of the selected material of wrapped pad;
T is the effective thickness of the selected material of wrapped pad.
As above-mentioned basic scheme, when the base plate of air-conditioner outdoor unit contacts with lower wrapped pad, first descend the A2 portion of wrapped pad to contact with base plate, because its corresponding parts compressor sinks, under complete machine Action of Gravity Field, δ 2 is compressed in advance.
Definite mechanism of δ 2 height is, complete machine gravity cuts after the gravity of A2 compressor that portion bears, the center-point of the whole Action of Gravity Field of base plate should be positioned at the center of lower wrapped pad bearing area, it is the center of B portion, can run-off the straight in the time of so just may guaranteeing that air-conditioner outdoor unit complete machine assembles, even if be subject to impacting, also larger inclination can not occur, so off-premises station integral protection effect is better.
In addition, after adopting the above-mentioned A2 δ of portion 2 height, main gravity has born in the B portion of lower wrapped pad, while being hit in bottom surface, can play main protective action, can't cause the distortion of footing, can effectively prevent the distortion of footing distortion and lower wrapped pad and break.
Based on above-mentioned design concept, for electric machine support, be also parts heavier on outdoor unit base, further optimization and the raising measure that can take be, the vertical height of described A1 portion is H+ δ 1, δ 1=(PA1/P) * ε * t.
PA1 is the stress value that electric machine support acts on A1 portion surface, and unit is KPa;
As above content, the advantage that lower packaging cushion for air-conditioning outdoor machine of the present invention has is, improve the Deformation Height in electric machine support, compressor region on base plate, under not increasing under the prerequisite of the whole usable height of wrapped pad, the harmony of lower wrapped pad whole height after raising distortion, can avoid the generation of footing distortion and complete machine tilt problem effectively.
Accompanying drawing explanation
Now in conjunction with following accompanying drawing, the present invention is further explained and is illustrated.
Fig. 1 is the structural representation of described lower wrapped pad;
The specific embodiment
Embodiment 1, and as shown in Figure 1, the lower packaging cushion for air-conditioning outdoor machine that the present embodiment provides mainly includes:
By functional regional division, include the A2 portion that supports compressor on the A1 portion of electric machine support on the B portion of unsplit bed(-)plate, the E portion that supports side feet and corresponding support baseboard, corresponding support baseboard.
The vertical height of B portion is H;
The vertical height of A1 portion is H+ δ 1, δ 1=(PA1/P) * ε * t;
The vertical height of A2 portion is H+ δ 2, δ 2=(PA2/P) * ε * t; Wherein,
PA1 is the stress value that electric machine support acts on A1 portion surface, and unit is KPa;
PA2 is the stress value that compressor acts on A2 portion surface, and unit is KPa;
P is the compressing stress of the corresponding density of the selected material of wrapped pad, and the relative deformation of EPS material is generally 10%;
ε is the percent strain of the corresponding density of the selected material of wrapped pad, generally gets 10%;
