The outward appearance that housing 10 constitutes according to the wash mill 100 of present embodiment, and the various inscapes of explanation will be installed on above-mentioned housing 10 in the back.At first, the place ahead of housing 10 is formed with peristome 14, and the door 12 that optionally opens and closes peristome 14.Therefore, the user can pass through open door 12, and washings is put into the cylinder 30 of housing 10 inside through peristome 14.

The set inside of housing 10 is useful on the bucket 20 of accommodating washings, the inboard rotatable cylinder 30 that is used to accommodate washings that is provided with of bucket 20.In this case, the inboard of cylinder 30 can be provided with a plurality of lifting devices 32, and under the situation of cylinder 30 rotations, above-mentioned lifting device 32 is used to promote washings, and it is dropped downwards.

The effect of above-mentioned lifting device 32 is: under the situation of cylinder 30 rotations, behind the lifting washings, washings is dropped, thereby improve scourability.And above-mentioned lifting device 32 is provided with a plurality of.For example, shown the situation that is provided with 3 lifting devices in the inboard of cylinder 30 according to the wash mill 100 of present embodiment, but the present invention is not limited to this.

In addition, detergent box 60 is supplied with stream 62 through the washing agent that is connected with bucket 20 and is supplied with washing agent and/or washings.The user gets into required stroke after detergent box 60 drops into washing agent, will supply with stream 62 via detergent box 60 and washing agent from the washings supply source washing water supplied of outside, and together supplies to barrels 20 inboard with washing agent.

In addition, in case wash mill 100 drives, in the stroke of selecting, for example in the washing stroke, cylinder 30 will rotate, and especially in the dehydration stroke, cylinder 30 will the high speed rotation.As stated, in case cylinder 30 rotations, bucket 20 inner washings or washing agent possibly supplied with stream 62 adverse currents through washing agent, and supply to detergent box 60.In case the washing agent adverse current, will cause the discontented of user to detergent box 60, and, because washings can flow into the inside of housing 10 through detergent box 60, therefore, will cause the fault of various inscapes, particularly control part etc.

Therefore, as shown in the figure, supply with stream 62 at washing agent and be provided with the bend 64 that is bent to form.In case form bend 64, supply with under the situation of stream 62 supplies through above-mentioned washing agent at washings and/or washing agent, even the supply of washings finishes, also will keep the state that a spot of washings are contained in bend 64 all the time.Therefore, under the situation of cylinder 30 rotations,, can prevent that the washings adverse current is to bucket 20 owing to be contained in the washings that washing agent is supplied with stream 62.

In addition, bucket 20 is by damper 60 resilient support of the spring 50 on top and bottom.Under the situation of cylinder 30 rotations, because the effect of spring 50 and damper 60 with the vibration that absorbs cylinder 30, therefore can not make above-mentioned transfer of vibration to housing 10.In addition, bucket 20 back is equipped with the drive division 40 that is used for head roll 30, and above-mentioned drive division 40 is to be made up of motor etc., thereby with rotatable drum 30.Above-mentioned drive division 40 is known by relevant practitioner, therefore will omit bright specifically at this.

And, can be provided with balance ball 70 according to the wash mill 100 of present embodiment.As shown in Figure 1, under the situation of cylinder 30 rotation,, will produce bigger noise and vibration according to the position of washings 1 if the inside of cylinder 30 contains washings 1.That is, when washings is not distributed in the inside of cylinder 30 uniformly, but concentrate under the situation of a certain position; If cylinder 30 rotations; Then will carry out ' centrifugal rotation ', because the unbalanced distribution of washings will cause producing bigger vibration and noise from the cylinder 30 of rotation.Therefore, for vibration and noise that the centrifugal rotation that prevents the aforesaid cylinder 30 that causes owing to the unbalanced distribution of washings causes, cylinder 30 is provided with balance ball 70.

Balance ball 70 is arranged at the cylinder 30 of rotation, preferably is arranged at the front side of cylinder 30.This be because, cylinder is when rotation such as stroke high speed such as dehydration stroke etc., washings generally is concentrated in the inboard of cylinder 30, i.e. rear side, at this moment, then in order to keep in balance with the washings of the rear side that concentrates on cylinder 30.

And, balance ball 70 is installed on cylinder 30, can prevent noise and vibration, therefore, the weight center is variable moves through making, and can guarantee the centrifugal rotation of cylinder 30.That is, the inside of balance ball 70 comprises the material with constant weight, and above-mentioned substance also includes the passage that can move to circumferencial direction.Therefore, under the heavy situation of the inner lateral deviations of cylinder 30, balance ball 70 inner materials will move distribution to the opposition side of a side that lays particular stress on, thereby can prevent noise and vibration that the centrifugal rotation owing to cylinder 30 causes.

In addition, in the structure of aforesaid wash mill 100, after washing finishes, because door 12 is in closing state, therefore, bucket 20 and cylinder 30 inner air can't be dredged with the outside smoothly.That is, bucket 20 and cylinder 30 inner air are kept the state of sealing basically.As stated,, will cause the washings fold, under the serious situation, also can cause residual peculiar smell in the washings if keep the state of sealing for a long time.

Therefore, in order to solve aforesaid problem, be provided with under door 12 closing state the structure that inner air of bucket 20 and external communications are circulated according to the wash mill of present embodiment.Below, will describe this structure.

In wash mill 100, under door 12 closing state,, include plural stream at least in order to make the air and the outer loop of bucket 20 inboards according to present embodiment.

Particularly, above-mentioned plural stream includes: be formed at the front side of bucket 20, allow air to flow into the 1st stream 90 of bucket 20 inside through detergent box 60; Be formed at the rear of bucket 20, bucket 20 inner air are discharged to the 2nd outside stream 95.

Detergent box 60 constitutes the drawer pattern, has the structure that can make the user be easy to load and unload and drop into washing agent.But aforesaid drawer pattern does not form complete closed structure, and therefore, the drawer of detergent box 60 will exchange with housing 10 air outside.Therefore, air outside can flow into inside through the 1st stream 90 that is connected in detergent box 60, thus, can supply with air outside to the inboard of bucket 20 through the 1st stream 90.

In this case, an end of the 1st stream 90 is connected in a side of detergent box 60, and the other end of above-mentioned the 1st stream 90 then connects along the front side of bucket 20.Usually, bucket 20 is by synthetic resin injection moulding, therefore, if the other end of the 1st stream 90 is directly connected in bucket 20, then has following problem,, under the situation of injection moulding bucket 20, need make grinding tool again that is.Therefore, under the situation according to connection the 1st stream 90 of present embodiment, the other end of the 1st stream 90 preferably is connected in the packing ring 22 in the place ahead that is arranged at bucket 20.

Packing ring 22 is the structures that connect bucket 20 and housing 10, is used to prevent that bucket 20 inboard washings from leaking.Above-mentioned packing ring 22 is made by the material with certain elastic force, therefore, is easy to connect the other end of the 1st stream 90.

Therefore, in case the other end of the 1st stream 90 connects along the place ahead of bucket 20, can prevent the adverse current of under the situation of cylinder 30 rotations washings etc.That is, the packing ring 22 that connects the other end of the 1st stream 90 approaches door 12 with extremely, and, with wash and the inside of the bucket 20 of dehydration etc. and cylinder 30 from a certain distance.Therefore, even cylinder 30 rotation at a high speed can prevent farthest that also washings that cylinder 30 is inner etc. are through the 1st stream 90 adverse currents.

In addition, in case an end of the 1st stream 90 is connected in the bottom surface of detergent box 60, the washing agent of detergent box 60 and washings will be through the 1st streams 90, and supply with through the place ahead of bucket 20.In this case, washing agent and washings might focus on the front side of bucket 20.For fear of this phenomenon, an end of the 1st stream 90 preferably connects along the sidepiece of detergent box 60.In addition, supply under the situation of detergent box 60 at washing agent and washings, even inner washing agent and the washings of detergent box 60 are farthest supplied with, it is ideal that an end of the 1st stream 90 also is unlikely to be washed the connected mode that water logging do not have.

In addition, an end of the 2nd stream 95 is directly connected in bucket 20, and the other end is then through the external communications of housing 10 with housing 10.Particularly, an end of the 2nd stream 95 is connected in the top, rear of bucket 20, thereby can make bucket 20 inner air circulation arrive outside.

In addition, because an end of the 2nd stream 95 is directly connected in bucket 20, therefore, under the situation of cylinder 30 rotations, bucket 20 inner washings might pass through the 2nd stream 95 adverse currents.Therefore, in wash mill 100, be provided with and prevent that cylinder 30 inner washings from passing through the structure of the 2nd stream adverse current according to present embodiment.Below, will carry out detailed explanation to this with reference to accompanying drawing.

Fig. 2 enlarges the oblique view that shows the 2nd stream 95 and the connecting portion of bucket 20.

With reference to Fig. 2, the connecting portion of the 2nd stream 95 and bucket 20 is provided with and prevents the washings adverse current, promptly prevent washings from the inside of cylinder 30 the connection valve 190 to the 2nd stream 95 adverse currents.

Above-mentioned connection valve 190 is made up of following parts: the connecting portion 192 that prolongs from bucket 20; Be arranged at the inside of connecting portion 192, liftable lift component 199; Be formed with the panel 194 of the peristome 195 that is optionally covered by lift component 199.

Connecting portion 192 prolongs the top, rear that is formed at bucket 20, and an end of the 2nd stream 95 is connected in connecting portion 192.Above-mentioned connecting portion 192 can form different members with bucket 20, perhaps also can be integrally formed with bucket 20.In fact, connecting portion 192 plays and makes the inscape that connects valve 190 be arranged at the effect of its inner shell.

The set inside of connecting portion 192 has with lower component: liftable lift component 199; Be formed with the panel 194 of the peristome 195 that is optionally covered by lift component 199.

Panel 194 crosses the section setting of connecting portion 192, and a side is formed with peristome 195, and ideal is that its central portion is formed with peristome 195.And the bottom of panel 194 is provided with liftable lift component 199.Therefore, rise and during descending motion,,,, then will open peristome 195 at lift component 199, thereby can make air pass through 95 circulations of the 2nd stream in case descend with the peristome 195 of closure panel 194 in case rise.

Lift component 199 is provided with the shielding portion 196 that is used to cover peristome 195, and main part 198.For under situation about rising, help closed peristome 195, above-mentioned shielding portion 196 can form the shape to the top protrusion, and is for example semicircle or oval.And main part 198 is connected with shielding portion 196, can perhaps also can form a member through the connection of other member between them.In addition, in order to float on the water, above-mentioned lift component 199 is preferably processed less than the member of water by proportion, has only and utilizes aforesaid material to process, could be under the situation of washings adverse current, and rise and cover peristome 195.

In addition, the above-mentioned structure that prevents adverse current for example connect valve and can be arranged at least one stream in the plural stream, and the setting of above-mentioned connection valve can suitably be regulated.

Below, will the driving that connect valve 190 be described with reference to accompanying drawing.

Fig. 3 is the sectional drawing that shows the state of lift component 199 declines among Fig. 2; Fig. 4 is the sectional drawing that shows the state of lift component 199 risings among Fig. 2.

With reference to Fig. 3, do not have at cylinder 30 under the situation of rotation, lift component 199 will be positioned at position shown in Figure 3 owing to deadweight.As stated, under the state that lift component 199 descends, bucket 20 inner air will be discharged to the outside along the direction of arrow, perhaps flow into the inside of bucket 20 the other way around from the outside.

In addition, in case cylinder 30 rotations, washings etc. to connecting portion 192, in this case, are full of adverse current because the inside of connecting portion 192 is washed water, and as shown in Figure 4, lift component 199 will rise owing to the effect of washings.The lift component 199 that rises will utilize shielding portion 196 to block the peristome 195 of panel 194, also will no longer rise simultaneously.Therefore, in case lift component 199 risings, and block peristome 195, can prevent that then washings from passing through peristome 195 adverse currents to the 2 streams 95.

Therefore, in case the rotation of cylinder 30 finishes, washings will be discharged to bucket 20 from connecting portion 192, and as shown in Figure 3, lift component 199 will descend again, and make air circulation.

In addition, be formed with a plural stream that makes the inner air circulation of bucket 20, that is, as stated, be formed with the 1st stream 90 and the 2nd stream 95, therefore more effective circulating air according to the wash mill 100 of present embodiment.

That is, if only form barrel stream of the air of 20 inside that is used to circulate, under the situation that cylinder 30 rotates at a high speed, negative pressure will appear in the inside of cylinder 30, therefore, housing 10 air outside flowed into, and can not make its circulation.In addition,,, also can't realize the inflow and the discharge of air, therefore, in fact also can't accomplish the circulation of air through a stream if only form a stream even do not have under the situation of rotation at cylinder 30.

But, as present embodiment, be formed with plural stream, that is, form the 1st stream 90 in the place ahead of bucket 20, and form the 2nd stream at the rear of bucket 20.Under the situation of cylinder 30 rotations, even negative pressure appears in the inside of cylinder 30, air also will arrive the inside of cylinder 30 and bucket 20 through the 2nd flow path, and discharge the air of bucket 20 inside through the 2nd stream 95.In addition, even do not have under the situation of rotation,, also can make the circulation of air more smooth and easy owing to form plural stream at cylinder 30.

The present invention is illustrated according to embodiment, should be appreciated that the foregoing description does not limit the present invention in any form, and all employings are equal to replacement or the technical scheme that obtained of equivalent transformation mode, all drop within protection scope of the present invention.
