The present invention relates to a window type air conditioner, and more particularly, to an apparatus for assembling a control unit of an air conditioner, which improves the structure of a control box and an arrangement of electronic components mounted in the control box.

In the conventional window type air conditioner, as illustrated in FIG. 1, an evaporator 20 is installed in front of the upper surface of the base panel 10 so as to heat-exchange the sucked indoor air with cold air. At the upper end of one side (right side) of 20), a blade frame 30 is formed to partition the discharge area so as to discharge the cold heat exchanged indoor air to the front of the product while passing through the evaporator 20.

In the blade frame 30, a plurality of vertical blades 40 are installed to adjust the flow of discharged air passing through the inside of the blade frame 30 in the left and right direction, the lower side of the blade frame 30 product The control box 60 is installed to accommodate the electronic component assay unit 50 for controlling the operation of the electronic pressing operation.

On the other hand, the outer panel 70 having a plurality of vents 71 on both sides to cover the remaining portion except the front of the product on the upper portion of the base panel 10 to form an appearance and circulate air to the outside of the product. ) Is coupled, and the front panel 80 is coupled to the front of the outer panel 70 to cover the front of the product to form the exterior and at the same time to suck and discharge the indoor air.

At this time, the front panel 80 is formed with a suction grill portion 81 to suck the indoor air at a position corresponding to the area of the evaporator 20, the blade frame 30 with respect to the front panel 80 The discharge grill portion 82 is formed to discharge heat exchanged indoor air at a position corresponding to the area of the discharge gas, and a plurality of discharge grilles 82 are disposed in the discharge grill portion 82 to control the flow of the discharged indoor air in the vertical direction. The horizontal blade 90 is installed.

In addition, a compressor 100 is installed at one center of the upper surface of the base panel 10 so as to supply cool refrigerant into the evaporator 20 by compressing the refrigerant circulated to high temperature and high pressure. The base panel 10 The outer side casing 110 for supporting the condenser (not shown) is installed at the rear of the upper surface of the upper side of the upper side, and between the outer side casing 110 and the inner side casing 120 at the center of the upper surface of each other. It is coupled by a plurality of interval maintaining bracket 130 with a predetermined left and right intervals so that the interval is constantly supported.

On the other hand, Figure 2 is an exploded perspective view showing an assembly unit of the control unit of the air conditioner, the control box 60 is bent in the shape of opening the front and rear at the same time the lower side center opening, the electronic component assembly 50 ) Is composed of a control panel 51, a panel PCB 52 (Panel Printed Circuit Board), a main PCB (53) assembled on the front side of the control box (60).

That is, the panel PCB 52 is coupled to the rear side of the control panel 51, and then the main PCB 53 is coupled to the rear side of the panel PCB 52, and then the front PCB 53 is connected to the front of the control box 60. Final assembly is completed in the order of assembling by a plurality of fastening screws 54.

However, the control unit assembling apparatus of the conventional air conditioner configured as described above is assembled to the rear side of the control panel 51 in the order of the panel PCB 52 and the main PCB 53, and the front side of the control box 60. Although there is an advantage that it can be assembled in the assembly structure, such as the overall size of the product (air conditioner), the panel PCB 52 when the space of the control box 60 and the electronic component assembly 50 are reduced. And only as part of the parts mounted on the main PCB (53) can be assembled as described above.

That is, when the parts of the entire product are reduced in size and the size of the control part is reduced, when the components constituting the electronic specification of the level satisfied by the consumers are mounted on both the panel PCB 52 and the main PCB 53, the space between the parts Due to the lack of electrical collisions caused malfunctions, product mass production and A / S repair is very difficult.

In addition, when some parts on the panel PCB 52 and the main PCB 53 are deleted while the size of the entire product is reduced and the size of the control unit is reduced, electrical collision may be avoided depending on the space between the parts. There is a problem in that the customer can not pursue the electronic specification that satisfies due to the deletion of parts.

Therefore, the present invention has been made to solve the above problems, the object of the present invention is to improve the structure of the control box and the assembly position of the main PCB, the size of the whole product is reduced and the size of the control unit is smaller Regardless, it aims to provide a control unit assembly device for an air conditioner that enables customers to install electronic specifications that satisfy customers and improve product quality.

The plurality of screw through holes 241 formed in the main PCB 240 are automatically matched with the screw holes 233 formed at the centers of the ends of the circular ribs 232, respectively.

At this time, the operator inserts the spiral surfaces of the prepared plurality of fastening screws 250 through the screw through holes 241 and tightens them to complete the assembly of the main PCB holder 230 and the main PCB 240.

Next, if the main PCB holder 230 is in close contact with the inner wall of the control box 200 to assemble the main PCB holder 230 and the control box 200 and the main PCB holder 230 is slid forward. The locking projections 234 each protruding from the upper and lower ends of the front outer surface of the main PCB holder 230 are protruded by the forming process to the inner wall of the control box 200 and inserted into the locking jaw 205 having one side opened. The assembly of the front side of the main PCB holder 230 and the front side of the control box 200 is completed, and then the screw passing holes of the fixing pieces 236 protruding from the upper and lower ends of the rear side of the main PCB holder 230, respectively. 235 is automatically matched with the screw holes 206 formed in the upper and lower ends of the inner side wall of the control box 200, respectively.

At this time, the operator inserts the spiral surfaces of the prepared plurality of fastening screws 250 through the screw through hole 235 and tightens them so that the rear side of the main PCB holder 230 and the rear side of the control box 200 are tightened. Complete the assembly.

Accordingly, the panel PCB 220 is assembled to the front side of the control box 200 via the control panel 210, and the main PCB (230) is connected to the inner wall of the control box 200 via the main PCB holder 230. 240 is assembled so that sufficient space is secured therebetween. Therefore, when the size of the entire product is reduced and the size of the control unit is reduced, the components mounted on the panel PCB 220 and the main PCB 240 may collide with each other. There is no concern, and the panel PCB 220 and the main PCB 240 can be equipped with all the parts of the electronic specification that the customer satisfies to improve the quality of the product.

As described above, according to the control unit assembly apparatus of the air conditioner according to the present invention, the panel PCB is assembled on the front side of the control box via the control panel, the main PCB inside the control box via the main PCB holder. Since the side wall is assembled perpendicular to the panel PCB, sufficient space can be secured between these panel PCBs and the main PCB. Thus, even if the size of the entire product is reduced and the size of the control unit is reduced, the panel The components mounted on the PCB and the main PCB do not have to worry about electric collision, and the panel PCB and the main PCB can be equipped with all the electronic specifications that satisfy the consumer, thereby improving the product quality.
