Detailed Description

Referring to fig. 1 to 3 in combination, according to an embodiment of the present invention, there is provided an air conditioner, especially a mobile air conditioner, including a housing, a lower air duct volute 1, a first fan blade 13 arranged in the lower air duct volute 1, an upper air duct volute 2, a second fan blade 23 arranged in the upper air duct volute 2, a compressor 101, a throttling element (not shown) and the like are arranged in the shell, the upper air duct volute 2 and the lower air duct volute 1 are superposed up and down, the compressor 101 is mounted on a chassis 100 of the housing, and the compressor further comprises a main driving part 3 and a first driven part 4, the main driving part 3 is in driving connection with one of the first fan blade 13 and the second fan blade 23, the first driven part 4 is in driving connection with the other one of the first fan blade 13 and the second fan blade 23, the main driving part 3 is in power transmission connection with the first driven part 4 through a first transmission part 5. In the technical scheme, one main driving component 3 is used as a source power, and the first transmission component drives other rotating components such as the second fan blade 23 or the first fan blade 13 to rotate, so that the structural form that the first fan blade 13 and the second fan blade 23 are respectively and independently provided with corresponding power components to drive in the prior art is simplified, on one hand, the internal mechanical structure of the air conditioner is simplified, on the other hand, the control structure of the air conditioner can be simplified, and further, the production and manufacturing cost of the air conditioner is reduced.

As a specific implementation manner, preferably, the main driving component 3 includes a driving motor, a driving shaft of the driving motor is coaxially connected with the first fan blade 13, and a stationary portion of the driving motor is installed on the lower air duct volute 1, that is, the main driving component 3 directly drives the first fan blade 13, and since the driving motor has a large weight, it is selected to directly drive and connect the driving motor with the first fan blade 13 located below the air conditioner at this time, so that a whole mass center of the air conditioner can be moved downward, and an attitude stability of the air conditioner is ensured, the first driven component 4 includes a first driven pulley, and the driving shaft is in power transmission connection with the first driven pulley through the first driving component 5. In order to more reasonably adjust the transmission ratio between the first driving pulley 31 and the first driven pulley, it is preferable that the first driving pulley 31 is coaxially connected to the driving shaft, and the first driving pulley 31 and the first driven pulley are in power transmission connection through the first transmission member 5. It should be understood that the main driving component 3 may also be coaxially and drivingly connected to the second fan blade 23, and details are not described here.

Further, a second driving pulley 32 is coaxially connected to the driving shaft, the first driving pulley 31 and the second driving pulley 32 are sequentially arranged along the axial direction of the driving shaft, and the water pumping device 7 (for example, a commonly-used water pumping flywheel for delivering water in the chassis 100 to the first heat exchanger 11 in a water pumping manner for cooling and heat dissipation) is further included, the water pumping device 7 is provided with a third driven pulley 71, and the second driving pulley 32 and the third driven pulley 71 are in power transmission connection through a second transmission component 8. The first driving pulley 31 and the second driving pulley 32, which are sequentially arranged in the axial direction of the driving shaft, can form a layered arrangement with respect to the first transmission member 5 and the second transmission member 8, thereby preventing interference therebetween.

The first transmission member 5 and the second transmission member 8 may be, for example, a chain transmission structure or a gear transmission structure, but the chain transmission structure has large impact and vibration and certain defects in form and position compensation, and the gear transmission structure has high requirements on installation space and installation accuracy, so that preferably, the first transmission member 5 is a first belt; and/or, the second transmission part 8 is a second belt, that is, the belt is used as the first transmission part 5 and/or the second transmission part 8, the belt structure can absorb vibration, and has high form and position compensation capability and installation flexibility, the requirement on the installation accuracy is low, the structure is simpler, and the cost is lower. Furthermore, the first belt and the second belt both adopt synchronous belts instead of conventional friction belts, so that the sliding loss in the transmission process can be effectively prevented, the tooth forms of the synchronous belts are meshed with similar gears, but the synchronous belts vibrate less than chains, meanwhile, the tensioning force is small, the bearing stress is reduced, the heat is less, and the weight is light.

The first fan blade 13 is preferably a centrifugal fan blade, the second fan blade 23 is preferably a centrifugal fan blade, the flow direction of the air flow can be reasonably arranged by using the centrifugal fan blade as an air flow driving component, the characteristics of axial air inlet and circumferential air outlet of the centrifugal fan blade are fully utilized, a first air inlet is constructed on the lower air duct volute 1, a first heat exchanger 11 is arranged on an air inlet path of the first air inlet, a second air inlet is constructed on the upper air duct volute 2, a second heat exchanger 21 is arranged on an air inlet path of the second air inlet, the first heat exchanger 11 and the second heat exchanger 21 are vertically arranged and are parallel to each other, and furthermore, a heat dissipation core part of the first heat exchanger 11 and a heat dissipation core part of the second heat exchanger 21 are positioned on the same vertical plane; the first heat exchanger 11 is tightly attached to the first air inlet, and the second heat exchanger 21 is tightly attached to the second air inlet, so that the lower air duct volute 1 and the upper air duct volute 2 are parallel to each other on the external contour, and the first heat exchanger 11 and the second heat exchanger 21 are parallel to each other on the external contour and are positioned on the same side, so that the internal space of the air conditioner is greatly optimized.

The lower air duct volute 1 is also provided with a first air outlet 12, and the air outlet direction of the first air outlet 12 faces to the horizontal direction; and/or a second air outlet 22 is further configured on the upper duct volute 2, and the air outlet direction of the second air outlet 22 faces upward.

In practical application, since the first transmission member 5 is connected between the first fan blade 13 and the second fan blade 23 in a transmission manner, and the center distance between the first transmission member and the second fan blade is relatively long, which causes the tension of the first transmission member 5 to be easily reduced in the application process, thereby causing the occurrence of the drive slip ineffectiveness, at this time, the tension adjusting device of the corresponding first transmission member 5 may be added, but this way will certainly increase the structural complexity and the manufacturing cost of the air conditioner, and for the air conditioner with the water pump 6, the setting position of the water pump 6 may be fully utilized, so that the tension of the first transmission member 5 can be adjusted while the water pumping function (pumping water with a preset height in the chassis 100 to dissipate heat on the first heat exchanger 11) is realized, specifically, the water pump 6 has the second driven pulley 61, the second driven pulley 61 is in power transmission connection with the first transmission component 5, preferably, the water pump 6 is connected to the lower air duct volute 1, and the relative position of the water pump 6 and the lower air duct volute 1 is ensured to be changeable, for example, a slide rail structure with a locking position is arranged between the installation base of the water pump 6 and the lower air duct volute 1.

It can be understood that, in order to ensure the smoothness and stability of the rotation of the second fan blade 23, it is preferable that it has a transmission shaft supported on bearings at both ends, and the bearings are disposed on the upper duct volute 2; in the same consideration, the drive shaft of the water beating component 7 is also supported on bearings at both ends, and the bearings are arranged on the lower air duct volute 1.

After the technical scheme is adopted, the air conditioner can drive the second fan blade 23, the water pump 6 and the water pumping component 7 through corresponding belt transmission by only one main driving component 3, and the main driving component 3 drives the first fan blade 13 at the same time, so that a driving mode with four driving modes is realized, the transmission mechanical structure is simplified to the greatest extent, and the number of the motors and the corresponding purchase manufacturing cost are reduced to the greatest extent.

Preferably, the rotation speed ratio of the first fan blade 13 to the second fan blade 23 is 1:1, so that the rotation speeds of the first fan blade 13 and the second fan blade 23 are synchronous; and/or when the water fetching component 7 is included, the rotating speed ratio of the first fan blade 13 to the water fetching component 7 is 1:1, so that the cooling capacity of the water fetching component 7 for fetching water to the first heat exchanger 11 is ensured; and/or, when the air conditioner comprises the water pump 6, the rotating speed ratio of the first fan blade 13 to the water pump 6 is 2:1, so that the design can ensure that the function of the improved air conditioner in the technical scheme is not changed greatly from that of the air conditioner before improvement, namely the function of the original air conditioner is not weakened, but the structure and the control are simplified, and the production cost is reduced.

It is readily understood by a person skilled in the art that the advantageous ways described above can be freely combined, superimposed without conflict.
