A kind of master control board box for reducing the refrigerator electromagnetic interference, on described master control board box, offer the first cable-through hole be used to wire is passed, on described master control board box, also be provided with the second cable-through hole be used to master control borad and frequency conversion plate connecting line are passed separately, described first and second cable-through hole is distributed in the diverse location of master control board box.
First and second cable-through hole is positioned at the diverse location of master control board box, allows master control borad and frequency conversion plate connecting line pass separately, has realized separating cabling with other wires, has reduced the electromagnetic interference between wire, thereby reduces the interference to the connection signal transmission.Best, first and second cable-through hole is distributed in position distant on master control board box, and namely the position of first and second cable-through hole its electromagnetic interference far away is less.
Further, described the first cable-through hole, the second cable-through hole be distributed in respectively master control board box two parallel sides or sides adjacent.
Further, described the first cable-through hole is opened in the upper left side of master control board box, and described the second cable-through hole is opened in the lower right side of master control board box.
The, two cable-through holes can also be offered in the following manner, and namely the first cable-through hole is opened in the upper right side of master control board box, and the second cable-through hole is opened in the lower-left side of master control board box.
First and second cable-through hole is distributed in the diagonal positions place of master control board box, makes master control borad and frequency conversion plate connecting line and other conductor spacings farthest, thus phase mutual interference minimum between the two.
Further, described the second cable-through hole is opened in the master control board box downside.The second cable-through hole is opened in to the master control board box downside, can reduce master control borad and and the connecting line distance of frequency conversion plate, equally also can reduce electromagnetic interference.
Further, in described master control board box, also be provided with one be used to placing the mounting structure of filter.By mounting structure, filter is arranged in master control board box, has shortened conductor length between filter and master control borad when having facilitated filter to install, effectively reduce interfering signal.Its mounting means can be welding or is threaded.
Further, described mounting structure is arranged on the inner bottom part of master control board box.
Further, described mounting structure is raised structures.
Further, described raised structures is provided with the screw hole for Fixed-Filter.The bolt of filter is penetrated to the screw hole of raised structures, and fix by nut.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is changed the master control board box structure, adjusts cable hole position and filter installation site, has reduced the interference between electrical part.Simultaneously, filter being arranged on to compressor bin need to put in hand in compressor bin in the past, and the narrow space of compressor bin own has again a lot of refrigeration pipes, and the installation of inconvenient filter is fixed.The mounting means that filter is placed on master control board box is not subjected to the restriction in space, than in the past, is arranged on the press storehouse and is easier to operation.
