In this embodiment, the cover body 5 is disposed at the opening 4 of the cover body 1, the cover body 5 is an independent component, and is taken down when the interference suppressor 2 needs to be installed in the cover body 1, and after the interference suppressor 2 is installed in the cavity 3, the cover body 5 is fixedly connected with the cover body 1, so that the interference suppressor 2 can be firmly fixed in the cover body 1, the fixing effect is better, the phenomenon that the interference suppressor 2 is separated from the cover body 1 due to the resonance effect generated by the vibration of the washing machine does not occur, and the noise can be reduced. Meanwhile, the cover body 5 and the cover body 1 are simple to mount and dismount, and assembly operation is facilitated.
One end of the interference suppressor 2 facing the cover body 5 is provided with a lead-out wire harness 7, one side of the cover body 5 facing the interference suppressor 2 is provided with an isolation channel 6 avoiding the lead-out wire harness 7, and the lead-out wire harness 7 is positioned in the isolation channel 6.
The leading-out wire harness 7 of the interference suppressor 2 can be connected with a line of the washing machine, in order to avoid the leading-out wire harness 7 and protect the leading-out wire harness 7, an isolation channel 6 is arranged on one side of the cover body 5 facing the cavity 3, and the leading-out wire harness 7 penetrates out of the isolation channel 6 to be connected with other lines. Because the opening of the cover body 1 faces downwards and the opening 4 of the isolation channel 6 faces downwards, even if the opening 4 exists, water cannot enter the chamber 3 under the action of the self gravity of the water, and the interference suppressor 2 can achieve a good waterproof effect while achieving the normal function.
The cover 5 includes an annular body 8 which is matched with the opening 4 and covers the opening 4, the inner periphery edge of the annular body 8 extends for a certain distance to one side of the interference suppressor 2 to form an isolation channel 6, and a lead-out wire harness 7 at the end part of the interference suppressor 2 is surrounded in the isolation channel 6.

The annular body 8 of the cover 5 is fastened at the opening 4 to at least partially shield the opening 4. To achieve this, the annular body 8 is sized and shaped to fit the opening 4. The middle of the ring-shaped body 8 is a through hole, the edge of which extends a certain distance to one side of the interference suppressor 2 to form an isolation channel 6. When in manufacturing, the die can be integrally formed, and the preparation is simple and convenient.
The isolating channel 6 extends a certain distance into the chamber 3, and a certain gap is formed between the outer wall of the isolating channel 6 and the inner wall of the housing 1. Thus, when the cover body 5 and the cover body 1 are fixedly connected by a certain connecting seam, the isolation channel 6 can also play a role of secondary protection. Even if the washing water penetrates into the interior along the fixed connection seam, the washing water can be isolated by the isolation channel 6, and the electrical components in the interior are protected from being damaged.
In order to better fix the interference suppressor 2, it is preferable that the isolation channel 6 extends along the central axis direction of the cover 5, and after the cover 5 is fixed to the cover 1, the extending end of the isolation channel 6 contacts the end of the interference suppressor 2, so as to fix the interference suppressor 2 in the chamber 3.
The isolation channel 6 that sets up on the lid 5 of this scheme centers on leading-out pencil 7 of interference suppressor 2 in it, not only can play the secondary guard action, further prevents that water from influencing interference suppressor 2, can also play spacing effect, conflicts the front end of interference suppressor 2 to support interference suppressor 2 and lean on the inner wall of cavity 3, play better fixed action, reduce the vibration of interference suppressor 2. In addition, the isolation channel 6 can also increase the strength of the cover 5, further enhancing the fixing effect.

The support ribs 12 have certain deformation capacity, and the cover body 5 can be detached by compressing the clamping blocks 14 inwards after installation. The supporting ribs 12 are limited in the cover body 1, and the outward deformation force of the supporting ribs can better press the clamping blocks 14 in the clamping grooves 15, so that the fixing effect is enhanced.
Furthermore, the length of the support rib 12 extending into the cover 1 is less than the length of the isolation channel 6, that is, after the opening 4 of the interference suppression device is installed downward, the joint between the clamping groove 15 on the outer surface of the cover 1 and the clamping block 14 is located below the opening 4 on the upper end of the isolation channel 6. Therefore, even if the washing water permeates from the joint of the clamping groove 15 and the clamping block 14, the isolation channel 6 can also play a role of secondary protection, and internal electrical elements cannot be damaged.
In a further scheme, the outer wall of the cover body 1 is provided with at least one mounting plane 16, and when the interference suppression device is mounted on the washing machine, the mounting plane 16 is in contact with the washing machine and is fixed on the washing machine.

The interference suppressing apparatus for a washing machine as claimed in claim 1, wherein the cover body and/or the lid body is further provided with a limiting structure for fixing the interference suppressor therein, the limiting structure comprising an axial limiting structure for limiting the axial movement of the interference suppressor and a circumferential limiting structure for limiting the radial movement of the interference suppressor.
4. The interference suppressing apparatus of claim 3, wherein the lead-out harness of the interference suppressor is disposed on a front end surface, and a protrusion is disposed on a rear end surface, and the axial limiting structure includes a front limiting rib and a rear limiting rib, the front limiting rib is disposed on the periphery of the isolation channel and extends along the central axis of the isolation channel toward the end of the interference suppressor to abut against the front end surface of the interference suppressor; the rear end limiting rib protrudes out of the inner wall of the cover body and abuts against the rear end face of the interference suppressor.
5. The interference suppressing apparatus of claim 3, wherein the circumferential position-limiting structure is a plurality of ribs disposed on the inner peripheral wall of the casing, and the plurality of ribs are distributed along the outer periphery of the interference suppressor; the inwardly extending end of each rib abuts against the outer peripheral wall of the interference suppressor.
6. The interference suppressing apparatus of claim 5, wherein the plurality of ribs extend in the axial direction of the housing for a predetermined distance to abut against the outer circumferential wall of the interference suppressor to restrict the circumferential movement thereof.
7. The interference suppressing apparatus for a washing machine as claimed in any one of claims 1 to 6, wherein the outer wall of the housing has at least one installation plane, and the installation plane is in contact with the washing machine and fixed to the washing machine when the interference suppressing apparatus is installed to the washing machine.
8. A washing machine having the interference suppressing apparatus as claimed in any one of claims 1 to 7, wherein the interference suppressing apparatus is fixedly mounted on the washing machine with the cover body on the top and the cover body on the bottom, and the lead-out harness of the interference suppressor is directed downward and connected to the wiring of the washing machine.
9. The washing machine as claimed in claim 8, wherein the cover and the washing machine are provided with a positioning claw and a positioning slot which are engaged with each other, and the interference suppressing device is fixed to the washing machine through the positioning claw and the positioning slot.
