According to the sealing structure of the washing machine, three oil seals are sequentially arranged on the main shaft 100 of the washing machine, when any one of the oil seals is damaged, the other two oil seals can still play a good sealing role, water leakage of the washing machine is prevented, and faults or safety accidents are avoided. Through set up bellied sealing part 11 on the outer lane of the first oil blanket 1 that is closest to the urceolus, after bearing frame 300 and rear flange 200 are assembled, sealing part 11 is compressed tightly to the clearance between sealed back flange 200 and the bearing frame 300 tip of filling, make between rear flange 200 and the bearing frame 300 sealed well, can prevent that water from spilling over from rear flange 200, effectively improved washing machine's waterproof performance, prolonged washing machine life. And moreover, the sealing structure of the washing machine can effectively prevent dust, so that the running stability of the washing machine is improved, and different use environment requirements of the washing machine are met. Especially to commercial washing machine, its operational environment is more complicated, and frequency of use is high, adopts this washing machine seal structure back, can effectively improve its reliability of use, reduces the maintenance number of times, reduces cost of maintenance.
Alternatively, referring to fig. 3, a side of the sealing part 11 facing the rear flange 200 is provided with first, second and third protrusions 111, 112 and 113, and the first, second and third protrusions 111, 112 and 113 are sequentially arranged along an extension direction of the sealing part 11. That is, the third protrusion 113 is located at an end of the sealing part 11, the first protrusion 111 is closest to the center of the first oil seal 1, and each of the three protrusions is provided with a circle on the sealing part 11, so that the sealing part 11 forms a concave-convex structure surface toward one side of the rear flange 200, and after the end of the bearing housing 300 and the rear flange 200 jointly compress the sealing part 11, the contact area between the sealing part 11 and the rear flange 200 can be increased due to the design of the concave-convex structure surface, the sealing effect of the sealing part 11 is improved, and thus the operation reliability of the washing machine is improved.
With continued reference to fig. 3, alternatively, the protruding surfaces of the first protrusion 111, the second protrusion 112 and the third protrusion 113 are arc surfaces, so that the sealing portion 11 faces one side of the rear flange 200 to form a wavy shape, when the end portion of the bearing seat 300 and the rear flange 200 compress the sealing portion 11, the design of the arc surfaces can enable the sealing portion 11 to be in seamless contact with the rear flange 200, avoid occurrence of contact gaps, further enhance the sealing effect of the sealing portion 11, prevent water leakage at the position of the rear flange 200, avoid failure of the bearing due to water inflow, prevent dust, sundries and the like from entering the bearing seat 300, and further improve the operation reliability of the washing machine.
Further, in the present embodiment, the thickness of the sealing portion 11 gradually increases in the extending direction thereof, and the projection heights of the first projection 111, the second projection 112, and the third projection 113 sequentially increase. That is, when the washing machine is just assembled, only the protruding surface of the third protrusion 113 of the sealing part 11 is in sealing contact with the rear flange 200, and when the washing machine is used for a certain period of time, the contact surface of the sealing part 11 may be worn, and only the third protrusion 113 is worn, so that the second protrusion 112 and the first protrusion 111 may still perform a good sealing function. That is, even if the sealing part 11 is worn, the second protrusions 112 and the first protrusions 111 thereon can ensure good sealing between the rear flange 200 and the bearing housing 300, prevent water leakage at the rear flange 200 of the washing machine, avoid bearing failure, and extend the service life of the washing machine.
In addition, the step structure design of sequentially increasing the heights of the first protrusion 111, the second protrusion 112 and the third protrusion 113 can better adapt to the inclined surface of the rear flange 200 (as shown in fig. 3), so that good sealing of the gap between the rear flange 200 and the end of the bearing seat 300 is ensured. Meanwhile, the above structural design overcomes the difficult assembly problem, when the assembly gap between the rear flange 200 and the bearing seat 300 is larger, only the third protrusion 113 and the rear flange 200 can be tightly pressed and sealed, and if the assembly gap between the rear flange 200 and the bearing seat 300 is smaller, the second protrusion 112 and the first protrusion 111 can also be contacted with the rear flange 200, and at the moment, the sealing effect is better.
Optionally, referring to fig. 3, a containing cavity 4 is defined between the first oil seal 1 and the second oil seal 2, and grease is filled in the containing cavity 4. Through filling a large amount of grease in holding chamber 4, can effectively prevent that the sealed lip of oil blanket from wearing and tearing too fast, when main shaft 100 rotates, the grease in holding chamber 4 can form the oil film between the lip of main shaft 100 and second oil blanket 2, and the oil film can effectively slow down the wearing and tearing of the sealed lip of oil blanket when contactless water or impurity, improves the leakproofness in the bearing frame 300.
Alternatively, referring to fig. 3, the first oil seal 1 has a corrugated structure 12 provided on the outer peripheral surface, the second oil seal 2 has an outer peripheral surface, and the third oil seal 3 has an outer peripheral surface. The three oil seals can be conveniently installed by the wavy structure 12, the contact area between the outer ring of the oil seal and the inner wall of the shaft hole of the bearing seat 300 can be increased, and the sealing effect is good.
Alternatively, referring to fig. 1 and 2, the second oil seal 2 and the third oil seal 3 are the same in size, and the first oil seal 1 is larger in size than the second oil seal 2. Since the first oil seal 1 is closest to the outer cylinder, it serves as a first waterproof structure of the bearing housing 300, and has a maximum size capable of effectively isolating dust and possibly leaked water to achieve an optimal sealing effect. Even if the first oil seal 1 is damaged due to abrasion, the second oil seal 2 and the third oil seal 3 still have good sealing effect, water is prevented from entering the bearing seat 300, bearing failure is avoided, and running stability of the washing machine is improved.
Further, in this embodiment, the first oil seal 1, the second oil seal 2 and the third oil seal 3 are all framework oil seals. The framework oil seal comprises a reinforcing framework, a sealing body arranged outside the reinforcing framework and a self-tightening spiral spring, wherein the reinforcing framework plays a role in reinforcing and supporting, and the oil seal can keep shape and tension. In a natural state, the inner diameter of the framework oil seal is smaller than the shaft diameter, namely, the framework oil seal has a certain interference. When the oil is packaged on the shaft, the pressure of the oil seal cutting edge and the contraction force of the self-tightening spiral spring generate certain radial tightening force on the shaft, after a period of operation, the pressure can be rapidly reduced or even disappear, and the self-tightening spiral spring can compensate the self-tightening force of the oil seal at any time.
The present embodiment also provides a washing machine including the main shaft 100, the outer tub, the bearing housing 300, and the sealing structure of the washing machine as described above. By arranging three oil seals on the main shaft 100 of the washing machine in sequence, when any one of the oil seals is damaged, the other two oil seals can still play a good sealing role, so that the washing machine is prevented from leaking water, and the washing machine is prevented from malfunctioning or having a safety accident. The sealing part 11 on the outer ring of the first oil seal 1 can seal and fill the gap between the rear flange 200 and the end part of the bearing seat 300, so that the waterproof performance of the washing machine is effectively improved, and the service life of the washing machine is prolonged. Meanwhile, the washing machine adopting the sealing structure of the washing machine has good dustproof performance, and particularly for commercial washing machines, the use environment is complex, the use frequency is high, and the sealing structure of the washing machine can effectively improve the operation reliability of the washing machine.
Optionally, referring to fig. 1 and 2, the washing machine further includes a first bearing 400 and a second bearing 500, the first bearing 400 and the second bearing 500 are sleeved on the main shaft 100 at intervals, the first bearing 400 is close to the outer cylinder, and the third oil seal 3 is attached to the first bearing 400. The first bearing 400 and the second bearing 500 serve to achieve rotation of the main shaft 100, reducing rotational resistance. If the first oil seal 1 and the second oil seal 2 are worn, under the blocking of the third oil seal 3, external water, dust and the like still cannot enter the bearing seat 300 easily, so that good waterproof and dustproof effects are achieved.
Alternatively, referring to fig. 1 and 2, the washing machine further includes a sleeve 600, the sleeve 600 being sleeved on the main shaft 100 and located at a side of the first bearing 400 near the outer cylinder, and inner rings of the first oil seal 1, the second oil seal 2 and the third oil seal 3 being in sealing contact with the sleeve 600. The sleeve 600 is used to assemble the first bearing 400 and the first, second and third oil seals 1, 2 and 3, and the sealing lip of the first oil seal 1 and the sealing portion 11 on the outer periphery thereof can prevent wash water, foreign materials, etc. outside the bearing housing 300 from entering the shaft hole of the bearing housing 300 at the initial stage of the use of the washing machine. If the sealing lip and the sealing part 11 of the first oil seal 1 are worn after the washing machine is used for a long time, external water may permeate over the first oil seal 1, and at this time, the second oil seal 2 can still block external water from entering the bearing housing 300. Likewise, if the second oil seal 2 is also worn partially, the third oil seal 3 can finally block water from entering the bearing seat 300, so as to ensure good waterproof and dustproof effects.
