Description
Technical field
The utility model relates to a kind of air-conditioner outdoor unit packing and defensive wrapped pad down of being used for, and belongs to household electrical appliance and mechanical design field.
Background technology
Be applied to the main protective action of following wrapped pad of existing air-conditioner outdoor unit, particularly aspect shock resistance, adopt polystyrene foamed (EPS) material basically.
The following wrapped pad that existing air-conditioner outdoor unit uses, its structure, shape and area fully match with the cooresponding external structure of outdoor unit base, with the purpose that is able to compatibly assemble and pack.Because the parts quality that the air-conditioning base plate interior is carried has nothing in common with each other.To overweight opposite side significantly like compressor one side; So directly cause wrapped pad each several part deformation extent and inconsistent down; In fact packaged complete machine is produced just and has been had a spot of inclination when rolling off the production line; After impacting (as falling) through transportation or bottom surface again, its degree of dip can be bigger, is easy to topple over and has the hidden danger of accidental damage.
Consider air-conditioner outdoor unit footing area features of smaller; Its area of contact with following wrapped pad is very little, and when transportation or bottom surface impact, footing deforms the most easily; Following wrapped pad also can be out of shape even fracture with the footing position contacting, causes complete machine to tilt to be prone to topple over.
The existing measure that can take to remedy is; For heavier air-conditioner outdoor unit; Greater impact and distortion that its wrapped pad often uses the material of density higher (foam expansion is lower) possibly occur with reply; But when the impulsive force of base plate is big, be easy to cause bottom deformation, also wasted material simultaneously, improved productive costs.
In view of this, the special present patent application that proposes.
The utility model content
Wrapped pad under the described air-conditioner outdoor unit of the utility model; Its purpose is to solve the problem of above-mentioned prior art existence and is directed against polystyrene foamed (EPS) or polyethylene foamed (EPE) material of being selected for use; Reasonably adjust the pad height in electric machine support on the corresponding supporting baseplate, compressor zone; Not increasing under the prerequisite of following wrapped pad entire effective height, improve the distortion back harmony of wrapped pad whole height down, thereby avoid the generation of footing distortion and complete machine tilt problem.
For realizing above-mentioned design goal, wrapped pad mainly includes under the described air-conditioner outdoor unit:
Divide the A2 portion of compressor on the A1 portion that includes electric machine support on the B portion that supports unsplit bed(-)plate, the E portion that supports side feet and the corresponding supporting baseplate, the corresponding supporting baseplate by functional area.
Wherein, the vertical height of B portion is H.The difference with the prior art part is, the vertical height of said 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 material that wrapped pad is selected for use;
ε is the percent strain of the corresponding density of material that wrapped pad is selected for use;
T is the effective thickness of material that wrapped pad is selected for use.
Like above-mentioned basic scheme, when the base plate of air-conditioner outdoor unit contacts with following wrapped pad, at first descend the A2 portion of wrapped pad to contact with base plate, because of its pairing parts compressor than heavy, promptly under the complete machine action of gravity δ 2 by compression in advance.
Definite mechanism of δ 2 height is; After complete machine gravity cuts the gravity of A2 compressor that portion bears; The center-point of the whole action of gravity of base plate should be positioned at the center of wrapped pad bearing area down, i.e. the center of B portion can run-off the straight in the time of possibly guaranteeing so just that the air-conditioner outdoor unit complete machine assembles; Also bigger inclination can not take place even receive impact, 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 following wrapped pad, can play main protective action when being hit in the bottom surface, can't cause the distortion of footing, can prevent effectively the footing distortion and down wrapped pad distortion and break.
Based on above-mentioned design concept, also be parts heavier on the outdoor unit base to electric machine support, further optimization and the raising measure that can take be, the vertical height of said 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 wrapped pad has under the utility model air-conditioner outdoor unit is; Improve the Deformation Height in electric machine support on the base plate, compressor zone; Not increasing under the prerequisite of following wrapped pad entire effective height, improve the distortion back harmony of wrapped pad whole height down, can avoid the generation of footing distortion and complete machine tilt problem effectively.
Description of drawings
Combine following accompanying drawing that the utility model is done further explanation and explanation at present.
Fig. 1 is the said structural representation of wrapped pad down;
The specific embodiment
Embodiment 1, and is as shown in Figure 1, and wrapped pad mainly includes under the air-conditioner outdoor unit that present embodiment provides:
Divide the A2 portion of compressor on the A1 portion that includes electric machine support on the B portion that supports unsplit bed(-)plate, the E portion that supports side feet and the corresponding supporting baseplate, the corresponding supporting baseplate by functional area.
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 material that wrapped pad is selected for use, and one is 10% for the relative deformation of EPS material;
ε is the percent strain of the corresponding density of material that wrapped pad is selected for use, and one gets 10%;
T is the effective thickness of material that wrapped pad is selected for use.
If the weight of air-conditioner outdoor unit is 118kg, compressor weight is 42kg, and motor and weight support frame thereof are 15kg, and the area of A1 portion is 53.25cm
2, the A2 area is 156.72cm
2, the compressing stress of following wrapped pad EPS relative deformation 10% is 60KPa, following wrapped pad effective thickness 60mm, then:
δ1＝15kg×10N/kg÷53.25cm2×10÷60KPa×10％×60mm≈2.8mm
δ2＝42kg×10N/kg÷156.72cm2×10÷60KPa×10％×60mm≈2.7mm
When the base plate of air-conditioner outdoor unit contacts with following wrapped pad, at first descend the A1 portion, A2 portion of wrapped pad contacts with base plate earlier, because of its pairing electric machine support and compressor all are heavy parts, δ 1, δ 2 height quilts are gone ahead of the rest and are compressed under the complete machine action of gravity.
Descend subsequently the B portion and the base plate of wrapped pad to be in contact with one another, and born all the other gravity of complete machine.
Because the area of B portion is maximum, can play main protective action when being hit in the bottom surface, can not cause footing distortion, the distortion and the problem such as break of wrapped pad down.And, also can reduce the global density of wrapped pad down, save raw MAT'L and reduce production costs.
The E portion that following wrapped pad contacts with the footing bottom surface should not stress under the complete machine quiescence basically, and only receiving in the bottom surface just can be stressed when impacting, therefore can prevent effectively the footing distortion and down wrapped pad distortion and break.
