Below tank 2, be provided with water discharge outlet 17 and drainage path 18, wherein, this water discharge outlet 17 is discharged the rinse water in tank 2, and this drainage path 18 is directed to the rinse water of discharging from water discharge outlet 17 outside of housing 1.In the way of drainage path 18, be provided with the draining valve 19 for opening and closing drainage path 18.Below tank 2, be provided with the water level detecting portion 33 for detection of the water level in tank 2.
In the way of circulation waterway 20, be provided with pump 21.By driving pump 21, the rinse water in tank 2 is incorporated in circulation waterway 20 from water discharge outlet 17.Then, the rinse water that flow into circulation waterway 20 is pressurized and sent water to swivelling chute 4, therefore can make the rinse water in tank 2 be recycled in tank 2 via circulation waterway 20.
In the anterior inner side of tank 2, see at the outer circumferential side of the circular peristome 5 that is arranged at tank 2 and be provided with nozzle water route 22 (with reference to Fig. 3) from rear side.Nozzle water route 22 is configured to be essentially circle, and this circle is than circumference 23 (with reference to the Fig. 2) more in the outer part that is set to circular peristome 6 in swivelling chute 4.
Be arranged at the peristome 5 of tank 2, the peristome 6 that is arranged at swivelling chute 4 and nozzle water route 22 and be formed as being separately essentially concentric circles.The inner peripheral portion 24 in nozzle water route 22 is positioned at the outside of radial direction compared with the circumference 23 of peristome 6.
Utilize the function of pump 21, the rinse water in tank 2 is directed in nozzle water route 22 from the inflow entrance 25 that is arranged at nozzle water route 22 via circulation waterway 20.Then, rinse water is directed into multiple nozzle 26a～26g (the also unified nozzle 26 that is designated as) of at least three above (examples of seven shown in Figure 3) being arranged at nozzle water route 22.Nozzle 26 is set to from nozzle water route 22 towards the axis of rotation 10 direction ejection rinse water of swivelling chute 4.
Between nozzle 26 and the circumference 23 of peristome 6, be provided with spatial portion 27.In spatial portion 27, be provided with reflecting part 28, this reflecting part 28 makes the rinse water spraying to spatial portion 27 from nozzle 26 reflect towards peristome 6.Reflecting part 28 is configured to and the rinse water spraying to spatial portion 27 is directed to peristome 6 and rinse water is imported in swivelling chute 4.
According to this structure, multiple nozzles 26 are formed on the position away from the circumference 23 of the peristome 6 of swivelling chute 4 separately, therefore can not make nozzle 26 expose from the peristome 6 of swivelling chute 4.In addition, multiple nozzles 26 are configured to the rinse water that can spray to the washings in swivelling chute 4 diffusion.Thus, in the time dropping into washings to swivelling chute 4 or take out washings from swivelling chute 4, washings can not tangled and damage by peristome 6.Thus, can provide a kind of be easy to take out put into washings, tumbling-box washing machine 50 easy to use.
In the present embodiment, be not formed for water guide wall of the jet flow of the rinse water spraying from nozzle 26 being directed to reflecting part 28 etc.Jet flow from nozzle 26 is being ejected into the spatial portion 27 shock surface 28a of shock-wave reflection portion 28 afterwards.
In addition, in the present embodiment, need to be for nozzle 26 not being made as to flat pattern along water guide wall.Therefore, the cross sectional shape of nozzle 26 can be made as to the circular hole shape in the situation downforce loss minimum of same sectional area.Thus, the flow of the rinse water spraying from nozzle 26 can be reduced and suppress, for bottom line, therefore can supply with to the washings in swivelling chute 4 rinse water of sufficient amount.In addition, utilize reflecting part 28 can make bar-shaped jet flow diffusion, therefore can spray rinse water on a large scale to the washings in swivelling chute 4, can improve cleaning performance and rinsing performance.
Reflecting part 28 is to be disposed in annularly peristome 5 around with the opposed mode of front surface portion of swivelling chute 4.And the mode that the shock surface 28a that the rinse water spraying from nozzle 26 will be impacted tilts with the jet direction with respect to from nozzle 26 arranges.Thus, can not make to disperse to multiple directions on shock surface 28a from the jet flow of nozzle 26, can make jet flow stably water, and the diffusion on one side of flowing along inclined plane on one side.Therefore, can supply with rinse water to the washings in swivelling chute 4 with stable disperse state.
In addition, shock surface 28a is more slow with respect to the angle of inclination of the jet direction from nozzle 26, more can make jet flow more stably water and diffusion.But, in the situation that reflecting part 28 is only made up of shock surface 28a, in the time that shock surface 28a is mild with respect to the angle of inclination of the emission direction from nozzle 26, cannot the deep inside direction guiding to swivelling chute 4 by jet flow, only can supply with rinse water to the clothing in the front in swivelling chute 4.
Therefore, in the present embodiment, in reflecting part 28, at the inner peripheral of shock surface 28a, guide portion 28b is set, this guide portion 28b is for the deep inside direction guiding to swivelling chute 4 by jet flow after impacting shock surface 28a from the jet flow of nozzle 26.
Like this, jet flow directed section 28b after impacting shock surface 28a, to the direction guiding in swivelling chute 4, therefore can supply with rinse water to the washings in swivelling chute 4 with stable disperse state.
In addition, in the present embodiment, will be made as than short in the length of shock surface 28a place guiding rinse water in the length (scope that jet flow contacts) of guide portion 28b place guiding rinse water.For the jet flow that makes to spray from nozzle 26 on shock surface 28a stably water, diffusion, need to form the region that the upper jet flow of shock surface 28a is contacted with the length more than impact range of jet flow.On the other hand, guide portion 28b has the function of the direction that only changes jet flow, therefore as long as contact is just enough in the short scope of Charpy face 28a.Thus, the flow velocity at guide portion 28b place can be reduced and suppress, for bottom line, can supply with rinse water to the washings in swivelling chute 4 more strong, can improve cleaning performance and rinsing performance.
As mentioned above, sent the rinse water of water to go out to axis of rotation 10 side sprays with bar-shaped jet flow from the multiple nozzle 26a～26g that are arranged at nozzle water route 22 by pump 21.The shock surface 28a that is ejected into the rinse water shock-wave reflection portion 28 of spatial portion 27, reflects to the peristome 6 of swivelling chute 4, and spreads to the direction of rotation of swivelling chute 4.Then, rinse water is passed through guide portion 28b near of the circumference 23 of peristome 6 to the interior ejection of swivelling chute 4.
In the outside of the circumference 23 of peristome 6, in being configured to be essentially circular nozzle water route 22, be provided with multiple nozzles 26.Each nozzle 26a～26g is configured to the emission direction that makes rinse water take the direction of the axis of rotation 10 towards swivelling chute 4 as benchmark, sees displacement angle (deviation angle) θ 1 in same direction with regulation from the opening surface side of swivelling chute 4.In the present embodiment, the displacement angle of each nozzle 26a～26g (deviation angle) θ 1 is set to equal angular.
According to this structure, can expand the scope that the rinse water that is ejected in swivelling chute 4 is passed through, therefore can be to the washings in swivelling chute 4 efficient and without omitting ground sustainable supply rinse water.In addition, if make displacement angle (deviation angle) θ 1 excessive, near can generation rinse water is not passed through axis of rotation 10 part.Therefore, as the example of avoiding near the part that generation rinse water is not passed through axis of rotation 10, expect the emission direction P of rinse water to be set as with respect to displacement angle (deviation angle) θ 1 of axis of rotation 10 displacements the half left and right (for example 5 degree～15 are spent) of the expanded-angle θ 2 (for example 10 degree～30 degree) of the rinse water spreading to the direction of rotation of swivelling chute 4.
As shown in Figure 4, be provided with the bellying 29 bloating to axis of rotation 10 sides of swivelling chute 4 in the part in nozzle water route 22.Planar portions 30 at this bellying 29 is provided with circular nozzle bore 31.By forming like this nozzle 26.
Length (thickness of the planar portions 30) L that nozzle bore 31 is configured to nozzle bore 31 is below the diameter d of nozzle bore 31.Planar portions 30 is orthogonal with the emission direction of the rinse water spraying from nozzle bore 31, tilts towards displacement angle (deviation angle) θ 1 of nozzle 26.
In bellying 29, separate with the main flow (dotted arrow in Fig. 4) that flows to the rinse water of end 22a in nozzle water route 22, therefore nozzle 26 is not vulnerable to the impact of the main flow of rinse water.Like this, by bellying 29 is set, can suppress the sinuous flow of the jet flow spraying from nozzle 26, can make the direction of sprayed rinse water stable.
In addition, can make jet flow at nozzle 26 place's contracted flows owing to there is bellying 29, therefore can improve flow velocity and strengthen the imposing manner of sprayed rinse water.Explain this effect.
Fig. 5 is the figure that represents the cross section structure of common nozzle 100 as a comparative example.
As shown in Figure 5, conventionally, in order to do one's utmost to reduce pressure loss, the internal face 103 that nozzle 100 is formed as nozzle water route 102 narrows smoothly gradually towards nozzle bore 101.According to this structure, the current that are about to can suppress in nozzle water route 102 in the time that nozzle bore 101 sprays to jet flow peel off to prevent sinuous flow from internal face 103, thereby form efficient nozzle 100.
In the case of the nozzle 100 of this structure, if the flow of jet flow is identical, determined by the sectional area of nozzle bore 101 from the flow velocity of the jet flow of nozzle bore 101.Thus, in order to improve the flow velocity of jet flow, need to make flow increase or reduce the sectional area of nozzle bore 101.
But in the present embodiment, in the time that the nozzle shown in application drawing 5 increases the circular flow of circulation waterway 20 from rinse water to nozzle water route 22 that supply with, the water level in tank 2 declines, and is easy to entrained air in pump 21.That is to say to produce and become the problem that so-called cavitation erosion state makes flow reduce on the contrary.In the present embodiment, in the case of the water yield in minimizing is accumulated in tank 2 is washed, the flow increase circulating in circulation waterway 20 is also restricted.In addition, if reduce the sectional area of nozzle bore 31, produce the problem in the reliabilities such as the end of a thread obstruction being produced by washings, the sectional area that therefore reduces nozzle bore 31 is also restricted.
Therefore, in the present embodiment, the bellying 29 bloating to axis of rotation 10 sides of swivelling chute 4 is set in nozzle water route 22 as shown in Figure 4, and around nozzle bore 31, the planar portions 30 vertical in fact with the perforation direction of nozzle bore 31 is set.Near current internal face 22b in the nozzle water route 22 being formed by bellying 29 will flow along internal face 22b due to the viscosity of fluid.But, in the time spraying from nozzle bore 31 as jet flow, about 90 degree of internal face 22b abrupt bend, therefore current are peeled off from the perisporium of nozzle bore 31.Therefore, as shown in Figure 4, the sectional area Q of jet flow is less than the sectional area R of nozzle bore 31.That is to say, make jet flow generation contracted flow by bellying 29 is set.
Like this, according to the nozzle 26 of present embodiment, even if flow is identical and the sectional area of nozzle bore 31 is identical with the sectional area of plain nozzle (Fig. 5), also can improve flow velocity compared with common nozzle, therefore can strengthen the imposing manner of the rinse water spraying from nozzle 26.
In addition, nozzle bore 31 is configured to and makes cross sectional shape (cross sectional shape at the E-E line segment place of Fig. 4) for circular.Thus, jet flow is contracted flow equably, therefore can suppress the sinuous flow from the jet flow of nozzle bore 31, can make rinse water spray and be sprayed onto on washings to the direction setting.In addition, nozzle bore 31 does not have angle, and the end of a thread therefore being produced by washings etc. is not easy to hang over nozzle bore 31 places, can prevent the hole plug being caused by the end of a thread etc.
In addition, as mentioned above, in the present embodiment, so that being mode below the diameter d of nozzle bore 31, the length L of nozzle bore 31 forms nozzle bore 31.If nozzle bore 31 is long on emission direction, temporarily peel off and current that contracted flow occurs can spray gradually diffusely from the perisporium of nozzle bore 31, lose the effect that improves flow velocity.Therefore, preferably the length L of nozzle bore 31 is made as below the diameter d of nozzle bore.Thus, the flow velocity from the jet flow of nozzle bore 31 can be improved reliably, the imposing manner of sprayed rinse water can be strengthened reliably.
In addition, in the present embodiment, as shown in Figure 3, nozzle water route 22 is configured to from inflow entrance 25 and is extended to both direction branch and towards two end 22a.According to such structure, cut apart by two in the path of the interior mobile water in nozzle water route 22.Thus, even nozzle water route 22 is formed as to ring-type more longways in the mode of surrounding peristome 5, also can shorten the path of current, can reduce the pressure loss in path.
As mentioned above, according to present embodiment, can apply enough pressure to each nozzle 26a～26g, can guarantee the flow velocity of the jet flow spraying from nozzle 26, can spray rinse water without omitting to the washings in swivelling chute 4.In addition, also nozzle water route 22 can be made as to the structure that is formed as ring-type that there is no end 22a.In this case, current, also from inflow entrance 25 to both direction branch, therefore can be brought into play the effect identical with the situation that is provided with end 22a.
In addition, in the present embodiment, being configured to and making rinse water is axis of rotation 10 directions (arrow S direction) of swivelling chute 4 from the direction in inflow entrance 25 flow nozzle water routes 22.According to this structure, can make the current of rinse water successfully to both direction branch.Thus, can apply enough pressure to each nozzle 26a～26g, can guarantee the flow velocity of the jet flow spraying from nozzle 26.
Turn back to Fig. 1, in the tumbling-box washing machine 50 of present embodiment, rear lower portion in housing 1 is provided with control part 32, this control part 32 is controlled motor 9, feed water valve 15, draining valve 19 and pump 21 etc., and program based on setting is controlled the action of washing, rinsing and each operation of dewatering.
Below, action and the effect of the tumbling-box washing machine 50 forming are as described above described.

User opens door 7 to the interior input washings of swivelling chute 4, makes tumbling-box washing machine 50 entrys into service.So control part 32 detects the amount of input washings.Afterwards, open feed water valve 15, rinse water is by the detergent dissolution being stored in detergent container 14, from water supply path 16 to the interior water supply of tank 2.According to beating washings that the effect of washing the sets water level that falls distance and set rinse water to rinse water in order to obtain, rinse water is accumulated to the below (water supply operation) in swivelling chute 4.
Utilize water level detecting portion 33 to detect the water level that is accumulated in the rinse water in tank 2.When accumulated the water yield of setting according to the amount of washings in tank 2 time, control part 32 stops water supply and starts matting.
In matting, to both forward and reverse directions, swivelling chute 4 is rotated to driving by motor 9.The washings of accommodating in swivelling chute 4 falls after direction of rotation is lifted at the projection body 12 of the cylindrical wall 11 that is arranged at swivelling chute 4.Like this, by beat wash be used for cleaning washings (low speed rotation operation).
The speed of swivelling chute 4 is now the speed that washings can not be attached at this degree of internal perisporium of swivelling chute 4.
As shown in Figure 9 B, carrying out after beating of stipulated time wash, control part 32 starts High Rotation Speed operation, and the speed that can be attached at this degree of internal perisporium of swivelling chute 4 with washings in this High Rotation Speed operation is rotated.In High Rotation Speed operation, the speed of swivelling chute 4 is the speed that washings can be attached at this degree of internal perisporium of swivelling chute 4, therefore washings is applied to centrifugal force.In High Rotation Speed operation, utilize this centrifugal force is peeled off dirt so-called centrifugal force from washings to clean.
In the time having carried out the High Rotation Speed operation of stipulated time, control part 32 carries out can not being attached at washings the low speed rotation operation (with reference to Fig. 9 A) that the speed of this degree of internal perisporium of swivelling chute 4 is rotated again.In the time having carried out the low speed rotation operation of stipulated time, control part 32 finishes matting.
Then, control part 32 is opened draining valve 19 and is started draining, dehydration procedure in the middle of starting.When having carried out after the balance control action of adjusting through laying particular stress on of the washings in swivelling chute 4 dehydration when action of stipulated time, the stop the rotation rotation of groove 4 of control part 32, dehydration procedure in the middle of finishing.
Then, start rinsing process.In the rinsing process of tumbling-box washing machine 50, the general speed that makes swivelling chute 4 can not be attached at this degree of internal perisporium of swivelling chute 4 with the washings in swivelling chute 4 on one side of control part 32 is rotated, and supplies water and beating type rinsing on one side.For example, be owing to making swivelling chute 4 be rotated the effect that produces beating type rinsing with the speed of 45r/min.But according to differences such as the kinds of the amount of washings and dirt, the speed that existence can be attached at this degree of internal perisporium of swivelling chute 4 by the washings with in swivelling chute 4 is rotated and water suction, the effective situation of centrifugal force rinsing of all washings.In this case, for example, make swivelling chute 4 be rotated with the speed of 100r/min while supply water, can make all washings absorb washings by supplying with recirculated water.In addition, by making swivelling chute 4 be rotated washings is applied to centrifugal force with the speed of 100r/min, therefore washings move laterally from swivelling chute 4 inner sides together with dirt, detergent ingredients.
, as shown in Figure 6A, the in the situation that of containing a large amount of washings in swivelling chute 4, sometimes can not obtain fully the effect of beating type rinsing.The washings that is particularly positioned at the central portion of swivelling chute 4 is not only always rotated at central portion periphery, and is difficult to absorb washings, is therefore difficult to obtain sufficient wash effect.That is to say, in rinsing process, if washings, by the fiber of washings, can be removed detergent ingredients, but as mentioned above, if can not make all washings absorb washings, can not expect wash effect.
Therefore, in the present embodiment, in the time that rinsing process starts, first make swivelling chute 4 can be attached at the washings in swivelling chute 4 the High Rotation Speed operation (with reference to Fig. 9 A) that the speed of this degree of internal perisporium of swivelling chute 4 is rotated.Now, adjust as required the balance control action of laying particular stress on of the washings in swivelling chute 4.But this stage is immediately to carry out conventionally, therefore mostly adjusted laying particular stress on of washings in swivelling chute 4 after middle dehydration procedure finishes.Therefore, can balance start well until High Rotation Speed, thereby can shorten the time.
If the rotating speed of swivelling chute 4 reaches washings is attached at the speed of this degree of internal perisporium of swivelling chute 4, control part 32 is opened feed water valve 15 and is carried out water supply start under the state that swivelling chute 4 is rotated.As shown in Figure 6B, the washings that is attached at the internal perisporium of swivelling chute 4 is dipped in the washings that are accumulated in tank 2 successively, and the Outboard Sections of the swivelling chute 4 of washings is rotated while absorbs washings.
When utilizing water level detecting portion 33 to detect in the time that the interior washings of tank 2 are accumulated to the first predetermined water level, utilize control part 32 to stop supplying water, carry out the injection of washings from nozzle 26.As shown in Figure 6 C, make washings be attached at swivelling chute 4 by High Rotation Speed, therefore form space at the central part of swivelling chute 4.Thus, can make the washings that eject from nozzle 26 directly contact the swivelling chute 4 inner side parts of washings.
Therefore, the inner side part of the swivelling chute 4 of washings also can absorb washings, match with above-mentioned water suction method (Outboard Sections of the swivelling chute 4 of washings is rotated while absorbs the method for washings), can make all washings absorb washings without omitting.In addition, as shown in Figure 6 D, by the centrifugal force of High Rotation Speed operation, washings are moved laterally together with detergent ingredients by fiber and from swivelling chute 4 inner sides.Like this, by carrying out so-called centrifugal force rinsing, also can effectively remove for the detergent ingredients being attached on the washings of the central portion that is positioned at swivelling chute 4.Therefore, can improve rinsing performance.
As mentioned above, in the present embodiment, utilize nozzle 26 to supply with washings while implement High Rotation Speed operation without omitting all washings in swivelling chute 4, can obtain efficiently thus the effect of the centrifugal force rinsing of expectation.
At this, as shown in Figure 7 A, suppose from a nozzle 26a, the washings A in swivelling chute 4～G to be supplied with the situation of washings.In this case, as shown in Figure 7 B, during swivelling chute 4 revolves and turns around, washings A～G separately (in the time of the washings that spray from nozzle 26a) carries out water suction and the dehydration of washings, carries out the removal of once washing agent composition.Thus, in order to obtain the wash effect of expectation, need implemented for long periods speed rotation operation, can not avoid the waste of long-term, the power consumption of activity time.
On the other hand, in the situation that being provided with multiple nozzle 26, driving pump 21 in High Rotation Speed operation, thus can always supply the washings in feed trough 2 to all washings of the internal perisporium that is attached at swivelling chute 4 without omitting via circulation waterway 20, nozzle water route 22 and multiple nozzle 26 etc.Thus, can avoid the problems referred to above.
, as shown in Figure 8 A, suppose that this seven supplies with the situation of washings to the washings A in swivelling chute 4～G from multiple nozzles 26, for example nozzle 26a～26g.In this case, as shown in Figure 8 B, during swivelling chute 4 revolves and turns around, washings A～G can carry out water suction and the dehydration of seven washings separately repeatedly.That is to say, compared with the situation that is a place with the nozzle 26 shown in Fig. 7 A, can within the identical time, remove the detergent ingredients of seven times.Thus, in the example of Fig. 8 A, can obtain the wash effect of seven times compared with the example of Fig. 7 A.Its result, also can bring into play identical effect even activity time is become to 1/7, therefore can shorten activity time, reduce power consumption.
Turn back to Fig. 9 A, carrying out after the High Rotation Speed operation of stipulated time, control part 32 finishes rinsing process, dehydration procedure in the middle of starting.In the middle of having implemented to transfer to after High Rotation Speed operation in rinsing process, dehydration procedure in the situation that, washings is the state that is attached at the internal perisporium of swivelling chute 4.Therefore, can omit balance control, dehydration procedure in the middle of can transferring to the short time.
As mentioned above, in the present embodiment, in the rinsing process after the middle dehydration procedure after matting finishes, do not carry out the stirring of low speed rotation and carry out High Rotation Speed operation.That is to say, can under washings is attached at the state of internal perisporium of swivelling chute 4, transfer to the High Rotation Speed operation in rinsing process, therefore can not hinder due to the balance control of washings the driving of swivelling chute 4.Therefore, can further shorten rinsing time.
In addition, in rinsing process, in High Rotation Speed operation, control part 32 also can repeatedly carry out repeatedly open draining valve 19 discharge the washings in tank 2 after again to the interior supply washings of swivelling chute 4 and from a series of actions of nozzle 26 spray rinse water.Thus, can further improve wash effect.This is due to compared with low speed rotation operation, carries out water suction and the dehydration of washings in above-mentioned centrifugal force rinsing with very high frequency.For example, implement the low speed rotation operation of two minutes and in centrifugal force rinsing, implemented twice rinsing centrifugal force rinsing one side's the high several times of dilution factor (degree of rinsing) with the activity time of a minute, the water consumption of 10L in the case of using the water of 20L.
In the time that the rinsing process of stipulated number finishes, control part 32 is opened draining valve 19 and is discharged the washings in tank 2.Afterwards, control part 32 the time of putting rules into practice swivelling chute 4 high-speed rotaries are transferred slough washings in finish running after the dehydration procedure of the washings that contain.In addition,, in the situation that tumbling-box washing machine 50 has dry function, also can use drying device after dehydration procedure, to carry out drying process.
As mentioned above, according to the tumbling-box washing machine 50 of present embodiment, can, from the many places ejection rinse water of the circumference of the peristome of swivelling chute 46, supply with washings to the washings in swivelling chute 4 without omitting.And, can be attached in the High Rotation Speed operation that the speed of this degree of internal perisporium of swivelling chute 4 is rotated at the washings with in swivelling chute 4, can improve rinse efficiency by spraying above-mentioned rinse water.
(the second embodiment)
