Abstract

The utility model provides a dewatering drum of a washing machine, which is used for solving the problem of the water leakage of a bearing seat on the dewatering shaft position. The utility model has the technical scheme that at least an annular water retaining rib is arranged on the back face on the drum bottom of the dewatering drum; the drum bottom face which is surrounded by the water retaining ribs is a sealing face without water drain holes; the horizontal plane of projection of the enclosed face is larger than the upper surface of the bearing seat; the annular water retaining ribs are arranged on the circular arc transition area on the back face on the bottom of the drum; the bottom face of the drum within the annular water retaining ribs is provided with no water drain holes and is a sealing face. Therefore, in the process of dehydration, the water can only be outwards exhausted along dewatering holes of the drum body and dewatering holes out of the water retaining ribs on the bottom of the drum; no water exists in the area on the lower part of the dewatering shaft; therefore, the phenomenon of water leakage on the motor is thoroughly eliminated, and the malfunction of motor damage, etc. caused by the water leakage can be eliminated.

Description

A kind of dehydrating vessel in washing machine

Technical field

The utility model relates to the dehydration barrel in washing machine/Water Extraction Machinery, specifically to the improvement of existing dehydration barrel structure.

Background technology

Dehydration barrel in existing washing machine or the Water Extraction Machinery, staving and the bucket in dehydration barrel has several leaking holes at the end usually.In the dehydration, the washings that throw away from leaking hole drop down onto at the bottom of the doubly-linked bucket bucket, discharge by drainpipe.An end bearing block is housed at the dewater bucket of a side of doubly-linked bucket, dehydrating shaft is inserted in the bearing block, and the water that spills at the bottom of the dehydration barrel flows on the bearing block.During dehydration, dehydration barrel is rotated at a high speed, long and for a long time it, may cause bearing block to leak, water can leak to motor, causes motor to damage.Although some manufacturers set about improving from bearing block, to try hard to eliminate seepy question, effect is also not obvious.For this reason, the someone designs a kind of new technique scheme, the patent No.: 92220539.6 is exactly an example.This technical scheme is, dehydrating shaft tighten overlapped one flat, opening down, and barrel-shaped rubber sleeve with the axle rotation, on the tension ring of dehydrating shaft, fixed the stand tee section around the rotation-formed ring-shaped rubber leather cup of dehydration, had interface to be communicated with mozzle under this leather cup, the openend of barrel-shaped rubber sleeve places in the ring-shaped rubber leather cup.When dehydration barrel leather cup wearing and tearing were leaked, water leaked on barrel-shaped rubber sleeve and enters in the ring-shaped rubber leather cup, by interface, flowed in the mozzle and discharged.The deficiency of this scheme is, 1, barrel-shaped rubber sleeve is contained on the dehydrating shaft equally, and follow high speed rotating, and can wear and tear equally and then drainage takes place.2, in doubly-linked bucket bucket bottom back side zone, the space is narrow relatively, and comparatively difficulty of barrel-shaped rubber sleeve and ring-shaped rubber leather cup is installed.3, when the high speed rotary dehydration, the same rotation at a high speed of barrel-shaped rubber sleeve, water leaks to the barrel-shaped rubber sleeve other position at the bottom of many be expelled at a high speed barrel, and does not flow in the ring-shaped rubber leather cup, discharges by the mozzle of setting.4, complex process has increased the washing machine manufacturing cost.Show fully that thus above-mentioned deficiency has influenced the enforcement of this technical scheme.

How solving above-mentioned deficiency, then is the design problem that the utility model faced.

Summary of the invention

The utility model provides a kind of dehydration barrel, and it can solve the seepy question that prior art exists.

In order to reach the purpose that solves the problems of the technologies described above, the technical solution of the utility model is, a kind of dehydrating vessel in washing machine, comprise dehydration barrel and the bearing block that is sleeved on the dehydration barrel axis, it is characterized in that: dehydration barrel bucket bottom back side has the annular water retaining ribs of a circle at least, and the bucket bottom surface that water retaining ribs is surrounded is the sealing surface that does not have dewatering hole.

In the utility model, also have following technical characterictic: the horizontal plane of described sealing surface is greater than the bearing block upper surface.

In the utility model, also have following technical characterictic: water retaining ribs is located on dehydration barrel staving and the arc transition face of bucket at the end.

In the utility model, also have following technical characterictic: bucket end dewatering hole is located on annular water retaining ribs and barrel bottom surface of bucket between the feather edge.

In the utility model, also have following technical characterictic: the altitude range of annular water retaining ribs is at 25～50mm.

The utility model compared with prior art has the following advantages and good effect: 1, bucket bottom back side arc transition zone is provided with annular water retaining ribs, the annular water retaining ribs does not have dewatering hole with interior bucket bottom surface, be sealing surface, and the horizontal plane of sealing surface is greater than the bearing block upper surface.Like this, in dehydration, draining can only discharge along the dewatering hole beyond staving dewatering hole and the bucket end water retaining ribs, thereby the zone of dehydrating shaft bottom, bearing block upper surface does not have draining, leak phenomenon to the motor from got rid of to leak at all downwards from bearing block, eliminated the faults of bringing because of leaking such as motor damage.2, because the bearing block place does not almost have draining, improve the working environment of bearing block, improved the reliability of service life and work.

Description of drawings

Below in conjunction with drawings and Examples the utility model is carried out at length description.

Fig. 1 is that dehydrating vessel in washing machine of the present utility model uses the user mode figure on two-tub washing machine;

Fig. 2 is the vertical view of the utility model dehydration barrel.

1, two-tub washing machine; 2, doubly-linked bucket; At the bottom of 2-1, the doubly-linked bucket bucket; 3, dehydration barrel; 3-1, staving; 3-1-1, staving leaking hole; 3-2, the bucket end; 3-2-1, bucket end dewatering hole; 3-2-2, bucket end sealing surface; 3-2-3, bucket end arc transition face; 3-2-4, annular water retaining ribs; 4, bearing block; 5, dehydrating shaft; 6, motor.

The specific embodiment

Referring to Fig. 1 and Fig. 2, at the bottom of bucket the 3-2 back side be provided with one the circle annular water retaining ribs 3-2-4, highly be 35mm, annular water retaining ribs 3-2-4 with bucket at the bottom of 3-2 be divided into two zones, zone be barrel at the bottom of the bucket bottom surface of water retaining ribs in surrounding, for there not being the sealing surface 3-2-2 of dewatering hole; Another zone be barrel at the bottom of water retaining ribs 3-2-4 to a bucket feather edge place, dewatering hole 3-2-1 at the bottom of in this zone, being provided with barrel.Like this in when dehydration, draining dewatering hole 3-2-1 at the bottom of the bucket discharges, and is blocked by annular water retaining disk 3-2-4, flow to 2-1 at the bottom of the doubly-linked bucket, the zone of dehydrating shaft 5 and bearing block 4 in the middle of can not entering, thus realize preventing that draining from leaking to motor 6 places from bearing block 4 downwards.

Certainly, the utility model is not limited to above-mentioned example, and in the utility model design concept essential scope, the utility model also has many variations, and remodeling adds or replacement, also all belongs to protection domain of the present utility model.
