The specific embodiment
Now embodiments of the present invention are described in detail, the example of embodiment illustrates in the accompanying drawings.All using identical Reference numeral to represent identical or similar parts as much as possible in the accompanying drawing.
Fig. 3 illustrates the sectional view of drum type washing machine according to the preferred embodiment of the invention, and Fig. 4 is the enlarged drawing of " B " part among Fig. 3.
Referring to Fig. 3, comprise according to the drum type washing machine of the embodiment of the invention: casing 11 is used for limiting therein predetermined inner space; Steel ladle 21 can be installed in the casing 11 quiveringly; Drum 31 is installed in rotation in the steel ladle 21; Drive part 41 is used to produce driving force to rotate drum 31; And sealing gasket 51, be used to seal the slit between drum 31 and the drum door 15.
Casing 11 is a cylinder shell, is formed with opening 13 in the front portion of casing 11, by opening 13 clothing is imported.Drum door 15 is connected in the opening 13 of casing 11 with opening/closing opening 13.Drum door 15 is outstanding to drum 31, thereby has sloping portion 15 ', so that form predetermined space between drum 31 and drum door 15.
Drive part 41 is supplied driving forces with rotation drum 31, and is installed in the rear surface of the spider 27 of steel ladle 21.Motor 42 comprises stator 42a and rotor 42b, and rotating shaft 45 presses embedding (pressedlyinserted) in rotor 42b.Rotating shaft 45 is supported rotationally by the bearing 47 that is arranged in the spider 27, and drum 31 is fixed in the end of rotating shaft 45.
First end of sealing gasket 51 is fixed in the end 31 ' of the opening of drum 31, and second end of sealing gasket 51 is the rubber parts of giving prominence to towards the sloping portion 15 ' of drum door 15.Sealing gasket 51 is along the peripheral annular setting of the circular open of drum 31.
As shown in Figure 4, according to present embodiment, second end of sealing gasket 51 extends towards the inside of drum 31, and scheme as an alternative, and second end of sealing gasket 51 can extend to the outside of drum 31 in case of necessity.
As Fig. 4 more specifically as described in, first end of sealing gasket 51 is fixed in crimping portion 31 in the mode that embeds ", this crimping portion 31 " in the end 31 ' of drum 31, form curlingly.Angle between sealing gasket 51 and the line that extends from the end 31 ' of the opening of drum 31 is acute angle (α).
Fig. 5 is the stereogram that sealing gasket is shown.
As shown in the drawing, first end 51 ' of sealing gasket 51 (it is fixed in the crimping portion 31 of drum 31 ") forms continuously; second end 51 of sealing gasket 51 " (it is connected in the sloping portion 15 ' of drum door 15) have at least one cutting part 53, wherein cutting part 53 along circumference with predetermined or irregular distance cutting.
Cutting part 53 can be cut into the V font.The diameter of first end 51 ' of sealing gasket 51 is greater than second end 51 of sealing gasket 51 " diameter, and second end 51 " under the situation that drum 31 slowly runs owing to elasticity is easy to separate with drum 31.This is because first end 51 ' of sealing gasket 51 is fixed in drum 31.
When drum 31 as in the washing process, stopping or when slowly running second end 51 of sealing gasket 51 " can be out of shape to separate with drum 31.Thus, second end 51 of sealing gasket 51 " kept the sloping portion 15 ' state of contact with drum door 15.Therefore the end 31 ' of drum 31 and the slit between the drum door 15 be by sealing gasket 51 sealings, thereby can prevent that clothing from entering in the slit between steel ladle 21 and the drum 31.Therefore, can prevent that clothing from entering between steel ladle 21 and the drum 31.
In addition, because sealing gasket 51 is made by the flexible material such as rubber, drum door 15 can not be out of shape, and perhaps can not produce noise.
When drum 31 high speed rotating, for example when rotary course (spinning cycle) medium speed surpasses 500prm, second end 51 of sealing gasket 51 " because centrifugal force and separating with drum door 15, and press to the inside of drum 31.Because the angle between the end 31 ' of the opening of sealing gasket 51 and drum 31 is acute angle (α), said process is successfully carried out by drum door 15.
In high speed rotating or rotary course, in drum 31 high speed rotating, the washings in the steel ladle 21 are discharged from.Therefore, clothing is compressed on the inner circumferential surface of drum 31 owing to centrifugal force, and clothing can not leave drum 31.Thereby sealing gasket 51 need not keep and drum door 15 state of contact.Thus, second end 51 of sealing gasket 51 " separate with drum 31 fully.Therefore, sealing gasket 51 of the present invention has the beneficial effect that prevents the noise that produces owing to the friction between sealing gasket 51 and the drum door 15 in drum 31 high speed rotating processes.
And, second end 51 at sealing gasket 51 " when embedding drum 31 and remaining in the end 31 ' of drum 31; owing to sealing gasket 51 has cutting part 53 (referring to Fig. 6); sealing gasket 51 can not be out of shape or twist, and second end 51 of sealing gasket 51 " can be firmly fixed at the end 31 ' of drum 31.
Set forth another embodiment of the present invention below with reference to accompanying drawing.
Fig. 7 illustrates the sectional view of drum type washing machine according to another embodiment of the present invention, and Fig. 8 is for illustrating the enlarged drawing of " B " part among Fig. 7.
At first, referring to Fig. 7, drum type washing machine comprises according to another embodiment of the present invention: casing 11 is used for limiting therein predetermined inner space; Steel ladle 21 can be installed in the casing 11 quiveringly; Drum 31 is installed in rotation in the steel ladle 21; Drive part 41 is used to produce driving force to rotate drum 31; And preventing member 251, it extends with the space between sealing steel ladle 21 and the drum 31 to steel ladle 21 from drum 31.
Prevent member 251 for to be fixed in the annular construction member of drum 31, and prevent that first end of member 251 is fixed in drum 31, prevent that second end of member 251 from extending to contact with steel ladle 21 to steel ladle 21.
Prevent that member 251 from forming by many thread brushes.Be fixed in the end 231 ' of drum 31 to steel ladle 21 outstanding guide members (guide member) 253, so that prevent that member or brush 251 are towards steel ladle 21.Guide member 253 is made by the flexible material such as rubber, so that guide member 253 can not damage owing to the collision with steel ladle 21.
With reference to Fig. 7 to Fig. 9, the operation of drum type washing machine according to the above embodiment of the present invention is described.
When drum 31 stopped or slowly running, brush 251 contacted with steel ladle 21.In addition, do not separate at brush 251 but contact and not under the state on the end 221 ' of steel ladle 21 brush 251 and drum 31 unitary rotation by guide member 253 with steel ladle 21 with steel ladle 21.
Therefore, clothing can not enter the space between steel ladle 21 and the drum 31.And, even between steel ladle 21 that is vibrating and the drum 31 that rotating, exist under the case of collision, also can be eliminated by brush 251 by the vibration that collision causes, and since the noise that collision produces can be absorbed by brush 251.
When drum 31 rotated with for example about 500rpm of high speed, clothing rotated with the state on the inner circumferential surface that is squeezed in drum 31 by centrifugal force.Therefore, can not produce clothing and be stuck in problem between steel ladle 21 and the drum 31.
And brush 251 can also separate with steel ladle 21 by centrifugal force.Thereby can prevent owing to the wearing and tearing and the noise that contact the brush 251 that causes with steel ladle 21.
Those skilled in the art should know under the situation that does not break away from the spirit and scope of the present invention can carry out various modifications and change to the present invention.Therefore, present invention is to be construed as various modifications of the present invention and the change that covers in the scope that falls into appended claims book and equivalent thereof.
