The similar convex lens of the shape of detachable cap 326, that is, towards outer rim, its thickness diminishes gradually from central part.Detailed says, top one side of above-mentioned body 322 is fixed in an end of above-mentioned detachable cap 326, and the other end is then unfettered.Therefore, above-mentioned detachable cap 326 does not hinder flowing of laundry water on single direction.
Detachable cap support portion 324 from the inner peripheral surface of body 322 towards detachable cap 326 formation protruding upward.Above-mentioned detachable cap support portion 324 above-mentioned detachable cap 326 from bottom support, and therefore, above-mentioned detachable cap 326 can only rotate along the proper flow direction of laundry water, and can not counter-rotation.
Therefore, the interval between the detachable cap support portion 324 (L) should be less than the length of detachable cap 326.
To shown in Figure 8, so-called U font connector 400 is the pipes (pipe) that are shaped as the U font like Fig. 6, and still, actual installation is the rear flank on the draining pump 220 of washing machine, and its shape presents the reverse U shape shape.The top of above-mentioned U font connector 400 presents streamlined, and a side at its streamlined position is formed with the air suction path 420 that can ventilate.And the bottom of above-mentioned U font connector 400 is formed with 2 tube connectors 410.Detailed says, one of them tube connector 410 is connected with draining pump 220 through scupper hose 300, and another tube connector 410 be connected with scupper hose 300 that the outside of body 322 is communicated with.
It is drum that air sucks path 420, and its inboard siphon breaker 430 that the adverse current phenomenon that can prevent siphonage and laundry water is installed that inserts.
The scupper hose 300 interior residual usually a certain amount of residual water that have that connect draining pump 220 and U font connector 400; And if produce draught head between the inside of above-mentioned U font connector 400 and the outside, the residual water in the above-mentioned scupper hose 300 will be discharged outside owing to the effect of siphonage.Therefore, in order to prevent the generation of above-mentioned siphonage, the present invention is provided with siphon breaker 430, thereby can avoid the inside and outside of above-mentioned U font connector 400 to produce draught head.
Like Fig. 6 and shown in Figure 9, siphon breaker 430 allows to suck from air the flowing of outside leaked-in air of path 420, and cuts off flowing of the laundry water that begins from the inside of U font connector 400.That is, laundry water can not be sailed against the current via above-mentioned siphon breaker 430.
Detailed says, above-mentioned siphon breaker 430 is to be made up of following parts: cropper main body 432; Be formed at the support portion 434 of an end of cropper main body 432; Be formed at the elastic variable portion 436 of the other end of cropper main body 432; Be formed at a plurality of embedding formulas protruding 438 on the outer peripheral face of cropper main body 432.
Above-mentioned cropper main body 432 probably forms drum, and the internal diameter of its diameter and above-mentioned air suction path 420 is complementary.Wherein, for be more prone to be provided with after the switching portion that states, the upper part diameter of above-mentioned cropper main body 432 is greater than the diameter of bottom.In addition, on the outer peripheral face of above-mentioned cropper main body 432 along protruding a plurality of embedding formulas protruding 438 that are formed with ring-type laterally in one week of outer peripheral face.
Insert under the state that is installed in air suction path 420 when siphon breaker 430, above-mentioned embedding formula protruding 438 can make above-mentioned siphon breaker 430 and air suck the more firm combination of path 420.And depression is formed with protruding accepting groove 422 on the inner peripheral surface of above-mentioned air suction path 420.And be provided with position and the shape size of above-mentioned protruding accepting groove 422 all are complementary with the position and the shape size of above-mentioned embedding formula protruding 438.Along with above-mentioned embedding formula protruding 438 is located in protruding accepting groove 422, siphon breaker 430 will be by firm fixing.
Perhaps; Air sucks the inboard of path 420 and does not set up the groove structure; But the equitant method of inner peripheral surface (behind the installation in position, embedding formula protruding 438 and air suck the inner peripheral surface mutual extrusion of path 420) of utilizing embedding formula protruding 438 and air to suck path 420 also can reach same effect.
Insert under the state that is installed in air suction path 420 when cropper main body 432, because the existence of above-mentioned support portion 434, cropper main body 432 will can not be absorbed in the inside of U font connector 400 fully.Therefore, under the acting in conjunction of aforesaid embedding formula protruding 438 and support portion 434, siphon breaker 430 will can arbitrarily not suck path 420 from air and come off, but the air that is installed in that can be firm sucks path 420.
Elastic variable portion 436 is formed at the bottom of cropper main body 432.Fashionable when air flow, above-mentioned elastic variable portion 436 will open, and will be cut off by above-mentioned elastic variable portion 436 with rightabout any the flowing of air-flow direction.Above-mentioned elastic variable portion 436 bottoms from cropper main body 432 are formed slopely downwards.And the inner peripheral surface of the end of inclination presents the flat pattern that closes each other.In other words, the similar whistle of shape of above-mentioned elastic variable portion 436 or the air inlet of the straight flute of octal (recorder).
In order only in a period of time that air flows into, to make elastic variable portion 436 open (elastic variable portion 436 receive air pressure and be out of shape), above-mentioned elastic variable portion 436 is to be made by elastomeric material.Moreover, also can whole siphon breaker 430 usefulness elastomeric materials be made.
After draining pump 220 is out of service, in case form negative pressure in the inside of U font connector 400, U font connector 400 air outside will flow into air and suck path 420, thereby siphon breaker 430 is opened.
That is, the inner peripheral surface of the elastic variable portion 436 that is closing each other owing to air pressure will break away from each other, thus the flare up cylindrical shape.At this moment, air just can flow through above-mentioned elastic variable portion 436 smoothly, flow into the inside of U font connector 400 then.Along with the inflow of air, the difference of the inside and outside air pressure of U font connector 400 will gradually become zero.Then, after the difference vanishing of above-mentioned inside and outside air pressure, the inflow of air will be interrupted thereupon.At this moment, because the effect of recuperability, switching portion will restore to original position, thereby inner circumferential surface returns to the state that closes each other, and sealing siphon breaker 430.
Below, will carry out detailed explanation to possessing the roller washing machine that constitutes as stated referring to figs. 2 to Fig. 9 according to one embodiment of the invention.Here, the correlation at each position of being associated of the flow direction of the draining flow direction of main explanation and the water of doing washing and air.
At first, have a look the flow direction of laundry water.In case at cylinder 110 inner beginning laundry operations, clean laundry water will supply to the inside of urceolus 100 through water supply installation.At this moment, laundry water will accumulate in the inside bottom of urceolus 100 successively.
Accumulate in the outside that urceolus 100 inner laundry water will pump to urceolus 100 through the draining pump 220 that is connected with urceolus 100.At this moment, the laundry water of pumping will be transported to scupper hose 300 through the flexible pipe joint portion 210 that is formed at pump case 200.
At this moment, the elbow elbow 310 that is combined in '
' word shape of scupper hose 300 ends is under the state that is combined in flexible pipe joint portion 210.In addition, the inboard of above-mentioned elbow elbow 310 adverse current of inserting the adverse current that the water that can prevent to do washing is installed prevents parts 320.
Under the situation of using U font connector 400, because the effect of siphonage, when draining pump 220 was out of service, the laundry water that left behind between U font connector 400 and the draining pump 220 was not that all to emit be exactly adverse current to arrive draining pump 220 1 sides.
Therefore, in order to prevent the generation of above-mentioned phenomenon, U font connector 400 is provided with the siphon breaker 430 that is used to prevent siphonage, and scupper hose 300 is provided with adverse current and prevents parts 320.
When doing washing water when the scupper hose direction is pumped, adverse current prevents that the detachable cap 326 of parts 320 from can move along the flow direction of laundry water, therefore can not hinder the normal discharging of laundry water.
But detachable cap 326 will be supported in detachable cap support portion 324, thereby make the above-mentioned detachable cap 326 can not be to the counter-rotation of laundry water flows direction.Therefore, even laundry water is sailed against the current, also can not let the laundry water flows arrive the inside of draining pump 220 once more.
The laundry water of being pumped by above-mentioned draining pump 220 will be successively via elbow elbow 310 and scupper hose 300, and pumps to U font connector 400.Then, laundry water will be successively be discharged to the outside of body 322 via the U font connector 400 that is positioned at draining pump 220 upsides with the scupper hose 300 of body 322 external communications.
In the middle of roller washing machine 10 runnings, if produce draught head between the inside and outside of U font connector 400, U font connector 400 air outside will flow into air and suck path 420, and open siphon breaker 430.
That is, because action of air pressure, the elastic variable portion 436 that is in the state of closing will open, thereby allow air to flow into the inside of U font connector 400.Because the inflow of air, the draught head between U font connector 400 inside and outsides will finally disappear, thereby can prevent the siphonage that produces because of draught head.
In a single day draught head disappears, because the effect of recuperability, the elastic variable portion 436 of siphon breaker 430 will seal again.At this moment, air suction path 420 will be under the closed state.Therefore, when the laundry water circulation, laundry water can not discharged through siphon breaker 430.
According to above-mentioned principle, can effectively prevent the phenomenon of water adverse current of doing washing, and can effectively discharge the inner residual water of urceolus.
Right of the present invention is not confined to aforesaid embodiment, but is decided by the record in claims.Under the situation that does not exceed the technical scope of putting down in writing in claims of the present invention, the technical staff of relevant industries can carry out various deformation and modification to it.
