Description

Air conditioner outdoor unit casing

Technical field

The present invention relates to a kind of air conditioner outdoor unit casing, particularly relate to the air conditioner outdoor unit casing that a kind of cost is low, simple in structure, make easily and can suppress to vibrate generation.

Background technology

Thereby air-conditioning is to be arranged at room, living room, office or shop etc. to locate to be used for regulating the device that temperature, humidity, cleanliness factor and the air-flow of air keep comfortable indoor environment.Usually air-conditioning comprises the compressor of compressible refrigerant; Condensation is compressed the condenser of refrigerant; Being arranged on condenser one side and having can be to the condenser air-supply outdoor location with the heat release electric fan that impels the refrigerant heat release; Be arranged at indoor and had the indoor set of the indoor heat converter of cooling effect.

Fig. 1 is the air-conditioner outdoor unit stereogram of prior art.Fig. 2 is the cutaway view along II-II line among Fig. 1.As shown in Figure 1, 2, air-conditioner outdoor unit comprises in order to suck or to discharge air and be provided with the external box of microvave 11 of air suction inlet 13 and outlet 15; Be arranged on the compressor 21 that is used for compression refrigerant in the external box of microvave 11; Be arranged near the outdoor heat converter the air suction inlet 13; Be arranged at the blowing fan 25 that external box of microvave 11 inner and upper can be carried out that air sucks and be discharged.External box of microvave 11 then comprises the rectangular metal base plate 12 that can place compressor 21 installation portions such as machine such as parts such as grade; Be positioned at metal base plate 12 tops and separated by a distance with it and with the corresponding rectangle upper lid 14 in its position; A plurality of vertical support frame 16a～16e that metal base plate 12 and upper lid 14 can be fused with four angles that are vertically set on metal base plate 12 and upper lid 14 and the long limit of side midpoint.On upper lid 14, be provided with a pair of outlet 15 for making the air that is drawn into external box of microvave 11 inside can be discharged into its outside smoothly.All be provided with catch net on air suction inlet 13 and the outlet 15.Below each outlet 15, all have and to utilize the fixed bar support 27 unsettled inside that are fixed on upper lid 14, more precisely be fixed on the blowing fan 25 in outlet 15 exits.When compressor 21 starting, will heat release in outdoor heat converter by the refrigerant of compressor 21 compressions, at this moment, blowing fan 25 will suck air outside by air suction inlet 13, and inhaled air then accelerates the refrigerant heat release by outdoor heat converter.The refrigerant of heat release will be by offering indoor set behind the not shown expansion gear puffings such as capillary in outdoor heat converter, and the refrigerant of finishing cooling effect in indoor set will come back to and compress in the compressor 21 and circulate in system repeatedly.But in case the air conditioner capacity of this prior art increases, the size of compressor 21 and blowing fan 25 also will increase thereupon, so the volume of external box of microvave 11 also will increase inevitably.In case the volume of external box of microvave 11 increases, when compressor 21 and blowing fan 25 runnings, its support strength will weaken relatively, thereby vibration may occur and make air-conditioner outdoor unit can not give full play to problems such as original due function.

Summary of the invention

In order to address the above problem, the object of the present invention is to provide the air conditioner outdoor unit casing that a kind of cost is low, simple in structure, make easily and can suppress to vibrate generation.

In order to achieve the above object, but air conditioner outdoor unit casing provided by the invention comprises the rectangular metal base plate of install machinery installation portion; Be positioned at the top of metal base plate and the rectangle upper lid of setting in parallel; Be vertically set on a plurality of vertical support frames that four angles of metal base plate and upper lid and the long limit of side midpoint can fuse metal base plate and upper lid; Have an end with at least one and be fixed in first vertical support frame upper end, the other end is along being top first tilting bar of the direction of angle theta to the extension of oblique below with the upper lid minor face, one end is fixed in second vertical support frame upper end, the other end and terminal top second tilting bar that links to each other of top first tilting bar, one end is fixed in the first vertical support frame lower end, the other end is along being bottom first tilting bar that the direction of angle theta is extended obliquely upward with the metal base plate minor face, one end is fixed in the second vertical support frame lower end, the other end and terminal bottom second tilting bar that links to each other of bottom first tilting bar, one end links to each other with the end of top first tilting bar with top second tilting bar, the bracing frame of the connecting rod that the other end links to each other with the end of bottom first tilting bar and bottom second tilting bar.

The angle that has 30 degree between described top first tilting bar and upper lid and bottom first tilting bar and the metal base plate.

Described top first tilting bar, top second tilting bar, bottom first tilting bar, bottom second tilting bar and connecting rod are integrated.

In air conditioner outdoor unit casing of the present invention, bracing frame can make between metal base plate, upper lid and the vertical support frame in conjunction with more firm, and cost is low, simple in structure, make easily, and can suppress vibration and produce.
