Description
Technical field
The present invention relates to a kind of washing machine, a kind of particularly front loading washing machine.The present invention is more particularly related to
And a kind of packing ring of front loading washing machine, the packing ring seals the inside anti-leak of staving and utensil.
Background technology
Front loading washing machine is well-known.In order to increase the convenience of user, such washing machine is generally also
Functions/drying is provided with to dry clothing by means of being heat-treated air.In this application, term " washing machine " is intended to bag
Include the front loading washing machine with functions/drying or without functions/drying.Washing machine is generally included in main body, main body
Staving, is rotatably disposed in staving make clothing surround the roller that rotation axis rotates, and with for entering roller
Opening front door.Generally, roller is connected to the axle of the motor behind staving.Roller has towards the opening at front door
Loading/unloading port.Moreover, staving has the hole being generally arranged concentrically with loading/unloading port of roller.Therefore, opened around this
Region between the front door of mouth and staving must be sealed by packing ring anti-leak.Generally, packing ring includes annular ring, for by ring
The opening at shape ring and front door circumference connection outward flange, and for by annular ring and the circumference in the hole of staving connection
Inward flange.In order to offset the vibration produced during roller rotates, staving is generally supported by damping mechanism.Therefore, in the operation phase
Between, staving and roller are in continuous relative motion relative to the opening at front door.Therefore, ring washer is usually provided with and outside
Edge and the flexible annular curved section of inward flange engagement, so as to allow the relative movement of staving and absorb vibration.
During the rotation of roller, the dress for being in close proximity to annular ring and roller is periodically moved in the clothes in roller
Region between the flange of load/unloading port.Therefore, during operation, clothing fairly frequently with packing ring friction.Accordingly, there exist
The risk of laundry damage, particularly rubs the vestige of rubber.Another risk is that clothing can be moved between staving and roller
Gap in.In order to prevent above-mentioned undesirable situation, packing ring is usually provided with the tongue that radially extends to make clothing
It is steered away from the region being in close proximity between roller and annular ring.Such tongue is commonly known as steering gear
(diverter).The T1 of TR 2,003 00616 disclose a kind of washing machine, and the washing machine includes the packing ring with steering gear.It is logical
Often, steering gear must the thrust to bear rotation clothing during washing process and drying process solid enough.Therefore, turn to
Device is generally made up of solid rubber.However, the manufacture of such steering gear is all relative in terms of material cost and labor cost
It is expensive.
The content of the invention
It is an object of the invention to provide a kind of packing ring and the washing machine with the packing ring, the power supply is in a cost efficient manner
Overcome the shortcoming of prior art and enough thrust can be realized and the clothing of sensitivity can also be gently treated.
The target is come via the packing ring such as limited in claim 1 with the washing machine as limited as claimed in claim 11
Realize.Further improvement project is obtained by the theme correspondingly limited in the dependent claims.
In the packing ring of the present invention, surface and tongue in being axially facing of tongue are axially facing outer surface
Each includes multiple flanks and multiple recesses.
By the present invention, particularly by means of the flank and recess, on the one hand, tongue it is rendered enough to it is solid with
Just the thrust of clothing being especially made up of weight fabric is born；On the other hand, tongue is relative to particularly by easily tearing
The clothing that fabric is made is rendered enough to softness.Thus, sensitive clothing can be gently diverted with away from the key
Region.Especially, due to making the contact area of tongue reduce and also increase by setting flank by setting recess
The flexibility of the exposed surface of tongue, so any rubber vestige eliminate or reduced as much as possible on clothing is endangered
Danger.By the present invention, the turning function of tongue is modified.Thereby, it is possible to improve the satisfaction of consumer.By the present invention,
Especially by means of recess, the amount of the rubber needed for manufacture tongue is also relative to be reduced, while not damaging its resilience.Therefore,
Manufacturing time (time particularly needed for sulfuration process) has also been shortened relatively.By the present invention, material cost and work
Power cost is by relative reduction.
In the packing ring of the present invention, flank and recess can set and be registered in a variety of ways the axle of tongue
To on apparent surface, and various sizes and shape can be presented.Thereby, it is possible to the thrust according to clothing and fabric
Type accurately adjusts the resilience of tongue.
In embodiment, flank and recess are arranged alternately.
In other alternate embodiments, the center of the flank in the axially opposed surfaces of tongue is correspondingly back-to-back
Positioning, or alternately change center to cause the flank in the axially opposed surfaces of tongue and recess relative to each other
Center is correspondingly back-to-back positioned.
In other alternate embodiments, flank and recess correspondingly have identical or different width.
In other alternate embodiments, flank and recess can have rectangular cross section, V-arrangement cross section, arc-shaped cross-section
Deng.
In another embodiment, the flank in the axially opposed surfaces of tongue is in the axial direction correspondingly away from that
This extension, and be substantially parallel to each other in radial directions.
In another embodiment, packing ring has the flexible bending section of one or more one, more easily to permit
Perhaps relative movement of the staving relative to front door.
In another embodiment, whole packing ring is molded as single part by rubber.
In another embodiment, tongue is located in the inner perimeter of annular ring, is especially close proximity to the loading of roller/unload
Carry hole and the flange across roller radially extends predetermined distance.Thus, the clothing moved towards the key area can be by
More reliably towards the center of roller to revolution to.
In another embodiment, packing ring is fixed on washing machine with so that tongue is positioned at the top side in staving hole
And it is extending radially downward.
