The specific embodiment
Existing separated floor room air conditioner is commonly called as cabinet-type air conditioner generally by housing, panel be placed in heat exchanger in the cavity that is formed by described housing and panel, blower fan system etc. and form; Described blower fan system is made up of fan blade, spiral case and motor; Described housing is made up of back board component, side plate, upper plate and lower shoe; Because foregoing is publicly-owned general knowledge, for for simplicity, will not illustrate in the accompanying drawing in this manual.As shown in Figure 1, 2, 3, described back board component is to be combined by spot welding by plate 1 after one and motor mounting plate assembly 2, is being formed with a cavity 6 between back plate and motor mounting plate assembly; Described motor mounting plate assembly 2 comprises motor mounting plate 3, motor fixing device 4 and Vibration damping block (not shown) etc.; The boss 5 of punch forming fixed electrical machinery on the described motor mounting plate 3, in spot welding on the above-mentioned boss 5 motor fixing device 4, described motor fixing device is generally screw or bolt; In assembling, described motor by the motor fixing device on the described motor mounting plate, is fixed on the described motor mounting plate.Described punching press comprises the deformation process that the forming machine device of use machine driving and liquid transmission carries out.
The manufacturing process steps of the back board component of air-conditioner in the prior art:
1, makes motor mounting plate, punch forming boss thereon;
2, make the motor mounting plate assembly: motor fixing device in the spot welding on the boss of moulding in previous step, and stick Vibration damping block at the back side of above-mentioned boss;
3, make the back board component: make the back plate, motor mounting plate assembly and the described back plate of finishing in the previous step made up by spot welding;
Shown in Fig. 4,5, be the back board component figure of the embodiment of the invention, described back board component is generally screw or bolt by the square back of block length plate 1 and the motor fixing device 4 that is fixed on the plate 1 of described back, combines; Described motor fixing device 4 is by pressing or the mode of spot welding is fixed on the plate of described back, and preferably the mode of pressing is fixed, and adopts pressure-riveting process to be connected with back plate, can avoid spot welding to get rusty, better guarantee perpendicularity simultaneously, can improve the quality of products, enhance productivity.The motor installation position 5 that the punch forming fixed electrical machinery is arranged on the plate of described back, described motor installation position can be boss or recess, described motor fixing device 4 is exactly to be fixed on the described motor installation position 5, and described motor is installed on the plate 1 of described back by described motor fixing device 4.The shape of described motor installation position 5 can be " cucurbit " shape as shown in the figure, also can be square, rhombus or other arbitrary shape.
The manufacturing process steps of back of the present invention board component:
1, makes back plate, punch forming motor installation position thereon;
2, make the back board component: press on the motor installation position of moulding in previous step or spot welding on motor fixing device;
In the more above-mentioned prior art manufacturing process steps of the manufacturing process steps of the back board component of air-conditioner and back of the present invention board component we can know that the advantage of the manufacturing process steps maximum of board component is behind the present invention: cancelled motor mounting plate; Cancelled the operation of sticking Vibration damping block at the back side of described motor installation position; Cancelled the assembly welding operation of motor mounting plate with the back plate.
Shown in Fig. 6,7, for adopting the spectrogram of the present invention front and back complete machine noise.In the system test performance, under all identical condition of other parts, when 360 rev/mins of identical motor speeds, adopting the complete machine noise of the air-conditioner of prior art is 42.4 decibels, and adopting the complete machine noise of the air-conditioner of the technology of the present invention is 39.6 decibels.In above-mentioned two spectrograms, we can also find to adopt the peak value of the present invention front and back noise also to drop to 26.1 from 29.7; The curve distribution situation of spectrogram has also obtained tangible improvement.After adopting the present invention as seen from the above comparison, because motor directly is fixed on the plate of back, can not be formed with a cavity, make the noise of complete machine reduce by 2～3 decibels, tonequality also is improved, thereby has improved product quality.
