Description
The present invention relates to clean the table-ware washing-machine of tableware with the method for sparging water purification.
Below in conjunction with the back Figure 14 that addresses is illustrated with regard to traditional table-ware washing-machine.
Tableware is put into plate-basket 42, put into entry into service behind the washing agent.And in case feedwater operation from the clean water of ormal weight to ablution groove 41 that supply with is at first carried out in the running beginning.Then, carry out the main operation of washing.Promptly the clean water after cleaning pump 43 pressurizations and heater via 44 heating is ejected from cleaning nozzle 45 with washing agent.Clean water and spray to vertical or oblique upper, clean 45 reaction forces that therefore spray of nozzle and horizontally rotate slightly from the spray-hole 46 of cleaning nozzle 45.Thereby the major part of cleaning water is to do to tilt to spray to the direction opposite with the direction of rotation of clean nozzle 45, impacts tableware.Tableware is the impulsive force by this clean water, and the effect of washing agent, heat etc. is cleaned.After the master who has passed through the stipulated time washes operation, just enter drainage procedure, promptly outside the clean water discharge machine that contains the dirt that washes from tableware.Be again then supply with the feedwater operation of cleaning water again, have for rinsing is residual washing agent and leftovers (dirt that adheres on the tableware also claims leftovers) tableware and from cleaning the rinsing process and the aforesaid drainage procedure of nozzle 45 sparging water purification, repeat 3 times so continuously after whole clean operation finish.In addition, 47 among the figure is control device that the running of cleaning pump 43, heater 44 etc. is controlled.
Yet as shown in figure 15, when this table-ware washing-machine drove, the track of its spray-hole 46 can only be concentric circles and move, so because shipwreck is sometimes cleaned to be flushed to or not flush at all in the position of tableware in plate-basket 42.Special when tableware is positioned at four jiaos of ablution groove 41, this phenomenon is just more outstanding.
In order to make its track reach wider scope by the track that changes this clean nozzle, develop another traditional table-ware washing-machine again, as shown in figure 16, this table-ware washing-machine have first clean nozzle 45 and be located at first clean on the nozzle, rotation freely second clean nozzle 48, its axis of rotation is than the first clean only eccentric L2 of nozzle 45.On this table-ware washing-machine, all parts identical with aforementioned conventional scrubber function are all used same reference numeral, and explanation is omitted.As shown in figure 17, the lower space of plate-basket 42 be provided with the radius of turn that horizontally rotates slightly be first of L1 clean nozzle 45 and rotation be located at freely first clean on the nozzle 45 and its axis of rotation than first clean the only eccentric L2 of nozzle 45, radius of turn is the second clean nozzle 48 of L3.First cleans nozzle 45 and second cleans spray-hole 46a and the 46b that nozzle 48 has the tableware sparging water purification in plate-basket 42.The 49th, the first nozzle bearing of nozzle 45 is cleaned in axle supporting first, and the 50th, the second nozzle bearing of nozzle 48 is cleaned in axle supporting second.Other first cleans nozzle 45 also has nozzle rotation special hole 51 in the side.
Table-ware washing-machine with regard to above-mentioned structure illustrates its action below.At first, tableware is put into plate-basket 42, and be loaded on the assigned position of ablution groove 41, entry into service then begins immediately to carry out to ablution groove 41 and supplies with the feedwater operation that ormal weight is cleaned water.Then, carry out the master and wash operation, promptly ejecting from first spray-hole 46a, the 46b that cleans the nozzle 45 and the second clean nozzle 48 with washing agent through the clean water of cleaning pump 43 pressurizations.At this moment first clean nozzle 45 and second and clean nozzle 48 and do the rightabout rotation mutually, no matter how its placement direction can both be cleaned reliably to make tableware in the plate-basket 42.That is, obtain the clean effect of regulation.
Wash operation in case passed through the master of such stipulated time, just enter the clean water that contains the dirt that washes from tableware etc. is discharged drainage procedure outside the machine.Be connected on after the drainage procedure is residual rinsing process and the drainage procedure that the tableware of washing agent and leftovers etc. is arranged of rinsing of supplying with the feedwater operation of cleaning water again, cleaning water from each clean nozzle ejection, after repeating 3 times so continuously, whole clean operation finishes.
As previously mentioned, the table-ware washing-machine of Shuo Ming the sort of conventional construction at first, it sprays track 46 as shown in figure 15 from clean water of cleaning nozzle 45 and spraying, fixes.That is to say that clean water can only spray repeatedly to the tableware that is placed on ad-hoc location.That is, accommodate in the field (to call clean field in the following text), exist clean water and directly impact tableware, clean high clean field of effect and clean water indirect stroke, clean the low clean field of effect at the tableware that constitutes by plate-basket.
Thereby, in order to obtain the cleaning strength of regulation in whole clean field, just must improve the cleaning strength of cleaning in the low clean field of effect, for this reason, except from spray-hole 46 directly impacts current of tableware, also must fully guarantee to be bound to behind water impact ablution groove 41 on the tableware and the secondary current that form.In other words, must increase expulsion pressure and flow from spray-hole 46, it is huge to clean the required clean hydrodynamic force of nozzle 45.Here the clean hydrodynamic force of being sayed is meant according to cleaning the energy that water expulsion pressure and flow are calculated.
In this occasion, if consider impulsive sound when cleaning the water slug tableware, then described expulsion pressure and flow are big more, and this impulsive sound is also big more.In fact, the spray-hole 46 of cleaning nozzle 45 is in close proximity to each other, and therefore is that the clean water from several spray-holes 46 impacts a tableware simultaneously.Therefore, the noise that is produced by the impact of cleaning water has very peak value, and along with the swing circle ground of cleaning nozzle 45 takes place.Clean noise in this operation process is not only very big from magnitude of physical quantity, and gives user's sensation also very big.And the thing followed is the occasion at big flow, and it is very big to impulsive sound or its sound that drips of ablution groove 41 to clean water, has further increased clean noise.
In addition, cleaning on the table-ware washing-machine that is provided with the second clean nozzle 48 on the nozzle 45 first of developing for the problem that solves above-mentioned the sort of traditional table-ware washing-machine, the second rotation radius of cleaning nozzle 48 can not freely be set.That is, be subjected to the restriction of factors such as the relative position relation of second pivot of cleaning nozzle 48 and the spray-hole 46a of the ablution groove 41 and the first clean nozzle 45 or weight balancing.In order to overcome this restriction, once did all effort.
One of solution is that second angle of cleaning the spray-hole 46b of nozzle 48 front ends that the setting of radius of turn L3 can not be too big is kept flat, and obtains turning moment thus.In other words, cleaning nozzle 48 with second is example, and as shown in figure 17, the distance L 3 that turning moment can be used as from pivot to spray-hole 46b shows with product with respect to the horizontal direction component F of the spray reaction forces of cleaning nozzle.In addition, angle and the washing (-)off properties of spray-hole 46b have confidential relation, put flat more difficult more cleanly, but but can obtain bigger turning moment.And the angle of spray-hole 46b is holded up, make near directly over, then difficult more acquisition turning moment, but washing (-)off properties can improve.
From above-mentioned reason, when adopting this method, washing (-)off properties can not reach very gratifying level, and if obtain abundant washing (-)off properties and the angle of spray-hole holded up, then can not obtain enough turning moments again.In addition, if at this moment there is foreign matter to enter the second nozzle bearing 50, then second rotary speed of cleaning nozzle 48 can reduce unusually, sometimes also can stall.In order to solve this point, also considered to use large-scale clean pump, but so produced new problems such as clean noise increase, size increase, cost increase again, therefore be difficult to realize.
Have again, even traditional first clean nozzle 45 and second clean nozzle 48 to resemble Figure 17 distance nozzle center be L1, L2 near the different spray-hole of spray angle of a plurality of sparging water purification is set, because the restriction of size, the water that is sprayed can be intersected with each other, can reduce the phenomenon of washing (-)off properties on the contrary.
Purpose of the present invention just is to provide a kind of table-ware washing-machine, and it can solve the existing problem of conventional construction, improves and cleans efficient.
The present invention also aims to provide a kind of table-ware washing-machine, it can reduce the peak value of the clean noise that produces when cleaning the water slug tableware, reduces the sound that drips that produces when cleaning ablution groove under the water droplet, can improve the intensity of clean nozzle etc. simultaneously.
First scheme that adopts for the purpose that realizes the present invention is, a kind of table-ware washing-machine, comprise ablution groove, accommodate the plate-basket, clean pump, clean nozzle of tableware with a plurality of spray-holes of sparging water purification to cleaning the water pressurization, it is characterized in that the curved shape that described clean nozzle adopts the direction of rotation when running to protrude.
The alternative plan that adopts for the purpose that realizes the present invention is, a kind of table-ware washing-machine, comprise ablution groove, accommodate the plate-basket, clean pump, clean nozzle of tableware with a plurality of spray-holes of sparging water purification to cleaning the water pressurization, it is characterized in that, described clean nozzle is the curved shape that protrudes towards the direction of rotation in when running, and is provided with connector in the side with the rightabout clean nozzle of direction of rotation.
For third party's case of the purpose usefulness that realizes the present invention is, a kind of table-ware washing-machine, comprise ablution groove, accommodate the plate-basket of tableware, to cleaning the clean pump of water pressurization, clean nozzle with a plurality of spray-holes of sparging water purification, it is characterized in that, described clean nozzle is cleaned nozzle off-centre by the first clean nozzle and the axis of rotation that are communicated with clean pump and horizontally rotate slightly than described first, clean the second clean nozzle that horizontally rotates slightly on the nozzle first and form, and first, second cleans and to have at least one to be the curved shape of the direction of rotation protrusion when it turn round in the nozzle.
The cubic case of the present invention is characterised in that, has at least the side of the clean nozzle of the opposite direction of rotation of direction of rotation with its running the time that connector is set in the clean nozzle of first, second in third party's case.
The present invention's the 5th scheme is characterised in that, second or cubic case in connector adopt antivibrating parts.

The effect of the present invention's first scheme is, uses the clean nozzle of the curved shape of the direction of rotation protrusion when running, has the clean water of phase difference from the spray-hole ejection time.That is to say that be not that water is cleaned in ejection simultaneously on same radius, but will clean aqueous dispersion, the noise that produces when therefore impacting tableware reduces greatly than traditional periodic peaks sound, magnitude of physical quantity is very low.
The effect of the present invention's alternative plan is, accepted in case behind the clean water that drips with connector, the impetus of cleaning water is just weakened, ablution groove then drips, because the buffer effect of this connector, the tonequality of impulsive sound is changed, and volume itself diminishes simultaneously, thereby impulsive sound is reduced greatly.In other words, when clean water directly dripped or impacts ablution groove, its sound that drips was ear-piercing tonequality, and because of ablution groove has than large space, also has acoustics, thereby can become very big by cleaning the sound that drips that water causes etc.Be located at the connector of cleaning nozzle this moment and just play a role, can reduce and clean the noise that produces when water falls ablution groove as the planar portions of the clean water of accepting to fall ablution groove halfway.In addition, described connector can also improve the mechanical strength of cleaning nozzle, particularly for the intensity of distortion.
The effect of third party's case of the present invention is, in case first or second any one that clean in the nozzle made the curved shape that protrudes to direction of rotation, then sufficient nozzle revolving force just can take place in the first or second clean nozzle, thereby, be located at the spray-hole of cleaning on the nozzle and just spray angle can be holded up helping and clean, clean efficient thereby table-ware washing-machine is improved.Another effect of this programme is, in case being cleaned nozzle, the first clean nozzle and second all makes the curved shape that protrudes to direction of rotation, though it is constant then to clean the radius of turn of nozzle, the total length of cleaning nozzle can extend, and can dispose the different a plurality of spray-holes of spray angle.In other words, the number of spray-hole, kind and spray angle can be done thinner adjustment, thereby can improve the clean efficient of table-ware washing-machine.
The effect of the cubic case of the present invention is, not only can suppress noise with connector takes place and strengthens to clean nozzle, and also can be revised by the distribution of weight that changes vibration-proof material for shape and the different weight imbalances that must cause of structure because of the clean mouth of the right and left, and can suppress leaking and uneven wear because of the uneven slipper that causes of weight.
The effect of the present invention's the 5th scheme is, goes to absorb near from falling the ablution groove top board a large amount of caused vibrations of impact of cleaning water with the connector that has set antivibrating parts, thereby can further suppress operating noise.
The effect of the present invention's the 6th scheme is, because whole clean nozzle all constitutes with antivibrating parts, thereby can reduce the noise that falls the clean water of ablution groove in the noise of cleaning the clean water that flows in the nozzle and the clean process.
The effect of the present invention's the 7th scheme is, because antivibrating parts adopts ad hoc structure, can make table-ware washing-machine more effectively reduce the mechanicalness intensity of noise and the clean nozzle of raising.

Below in conjunction with description of drawings the 1st embodiment of the present invention.
Figure 1 shows that the unitary construction of present embodiment.The 1st, ablution groove, the 2nd, tableware to be housed and to be positioned over plate-basket in the ablution groove 1, it is benefited from the injection of the clean water of cleaning pump 3, heater 4 pressurized, heated and is cleaned.The 5th, control device, to the feedwater of table-ware washing-machine, clean, a series of actions such as rinsing, draining, drying control.6 are arranged on the clean nozzle of the lower space of aforementioned plate-basket 2, and it has spray-hole 7a, 7b, 7c to plate-basket 2 sparging water purification.Clean nozzle 6 is subjected to horizontally rotating slightly from the clean water reaction of spray-hole 7a, 7b, 7c injection, adopts shape shown in Figure 2 in this example.That is, adopt the curved shape that protrudes to direction of rotation.In addition, the 8th, to cleaning the in addition nozzle bearing of axle supporting of nozzle 6.
Below be illustrated with regard to the action of present embodiment.Tableware is put in the plate-basket 2, and plate-basket 2 is loaded on entry into service behind the assigned position of ablution groove 1, just begin to carry out to ablution groove 1 and supply with the feedwater operation that ormal weight is cleaned water.Then clean 3 pairs of clean water pressurizations of pump, eject the clean water and the washing agent of process pressurization from spray-hole 7a, 7b, the 7c that cleans nozzle 6.Just carry out the main operation of washing.Finish in case the master of stipulated time washes operation, just begin to carry out and to contain the clean water of washing the dirt that falls from tableware and discharge drainage procedure outside the machine.Being connected on behind this drainage procedure is to supply with the feedwater operation of cleaning water again, and main operation, rinsing process, the drainage procedure washed repeats 4 times so continuously, and whole clean operation finishes.The elemental motion of more than cleaning operation is identical with traditional table-ware washing-machine.
Present embodiment is characterised in that as shown in Figure 2, cleaning nozzle 6 is the curved shape that protrudes to direction of rotation.Be located at the relative spray-hole 7a formation of the spray-hole 7b, the 7c that clean on the nozzle 6 angle of lag A, B thereby make.Because this angle of lag A, B arranged, from the sparging water purification of spray-hole 7a, 7b, 7c just be not on the same radius simultaneously the tableware in plate-basket 2 spray, reduced the overlapping scope of sparging water purification, can implementation efficiency good be clean.
When adopting present embodiment, owing to disperseed clean water, the magnitude of physical quantity of the clean noise that produces when impacting tableware reduces greatly than original periodic peaks sound.Self-evident, clean the emitted dose of water in the present embodiment with identical originally, so can not reduce washing (-)off properties.
Below in conjunction with Fig. 3 the present invention the 2nd embodiment is described.The same Fig. 1 of present embodiment unitary construction is so explanation is omitted.The 26th, be arranged at the clean nozzle of plate-basket 22 lower space, have spray-hole 27a, 27b, 27c to plate-basket 22 sparging water purification.And it is identical with previous embodiment 1 to clean nozzle 26, is the curved shape that protrudes to direction of rotation.In addition, present embodiment is cleaned the connector 29 that its both ends of handlebar are connected with two place's bending protuberances on the nozzle 26 as shown in Figure 3, and this connector 29 is a global formation with clean nozzle 26.The surface of this connector 29 is the plane.And connector 29 both can resemble Fig. 4 and connected both ends and the two place's protuberances of cleaning nozzle 26 with the form with large surface area, also can resemble Fig. 5 to connect two place's mid portions of clean nozzle 26 than the form of small size.
Below the action of present embodiment is illustrated.Identical about the elemental motion of cleaning operation with aforementioned the 1st embodiment, so explanation is omitted.
In carry out cleaning operation and rinsing process process, the clean water that sprays from spray-hole 27a, 27b, 27c is run into the ablution groove 1 that drips behind the tableware.The clean water generates in the ablution groove 1 of the dripping sound that drips.In the present embodiment, have connector 29 because of cleaning nozzle 26, this moment, this connector 29 just can be accepted the clean water of the part that is sprayed onto tableware, thereby played cushioning effect.The sound that drips of clean water etc. that is to say that if clean water directly drips or impacts ablution groove 1, the tonequality of its sound that drips is ear-piercing, and because ablution groove 1 has bigger space, has acoustics, so can become very big.Thereby accept the clean water that once drips with connector 29, the ablution groove 1 that drips again after the impetus of cleaning water is weakened is because the cushioning effect of this connector 29 changes the tonequality of the impulsive sound of water, volume itself also becomes very little simultaneously, thereby greatly reduces noise.
And because this connector 29 as Fig. 3, Fig. 5 or shown in Figure 4, greatly to being anti-S shape, so especially have humidification for the direction of twist of cleaning nozzle 26, can improve withstand voltage, hear resistance, the i.e. reliability of the clean nozzle 26 of raising.
Below in conjunction with Fig. 6 the present invention the 3rd embodiment is described.The unitary construction of present embodiment is also identical with Fig. 1, and explanation is omitted.36 for having the clean nozzle of spray-hole 37, identical with aforementioned each embodiment, is the curved shape that protrudes to direction of rotation.And identical with the 2nd embodiment, its periphery and connector 29 are global formation.Present embodiment is adhesively fixed the antivibrating parts 40 that constitutes at iron plate upper berth one deck plastics for example after having finished above-mentioned moulding with connector 29.Present embodiment is the antivibrating parts 40 that is adhesively fixed on connector 29 and has vibration-isolating effect, and if clean nozzle itself just usefulness have the material manufacturing of vibration-isolating effect, ought to obtain same quiet effect.
The below action of explanation present embodiment.The elemental motion relevant with clean operation is identical with the 1st embodiment, so explanation is omitted.Present embodiment is to have set antivibrating parts 40 on connector 29.So can not only fall the sound that drips that causes and carry out sound insulation to cleaning water, even near the top board of ablution groove 1, fall and impact when cleaning nozzle 36 when a large amount of water of cleaning, also can fully absorb and impact the vibration that causes, thus the generation of inhibition noise.
Very to the weight imbalance that must not take place simultaneously for shape and structure at clean nozzle the right and left, also can be easy to be revised, can also easily suppress uneven wear because of the uneven slipper that causes of weight by the distribution of weight that changes vibration-proof material.
Below in conjunction with Fig. 7 the present invention the 4th embodiment is described.1 is ablution groove among the figure, 2 is the plate-basket that places in the ablution groove 1, accommodates tableware, 3 is to cleaning the clean pump of water pressurization, and 4 be heater, 5 be to table-ware washing-machine feedwater, clean, control device that a succession of action implementations such as rinsing, draining, drying are controlled.The 6th, be located at the lower space of plate-basket 2, the radius of turn that horizontally rotates slightly is that first of L1 cleans nozzle, be communicated with clean pump 3.9 be provided in a side of described first clean on the nozzle 6, radius of turn is L3 and rotatable freely second clean nozzle, it is L2 that its axis of rotation departs from first distance of cleaning the axis of rotation of nozzle 6.Second cleans nozzle 9 as shown in Figure 8, has the curved shape that the direction of rotation when running is protruded.First cleans nozzle 6 and second cleans spray-hole 10a and the 10b that nozzle 9 has the tableware sparging water purification in plate-basket 2 respectively.11,12 be respectively the first nozzle bearing and the second nozzle bearing that the nozzle 6 and the second clean nozzle 9 are cleaned in axle supporting first.
The following describes the action of present embodiment.Tableware is put into plate-basket 2, and begin rotation after being placed in assigned position in the ablution groove 1, promptly begin to carry out to ablution groove 1 and supply with the feedwater operation that ormal weight is cleaned water.Then, execution will be washed operation with washing agent from first master who cleans the nozzle 6 and second clean nozzle 9 ejections through the clean water of cleaning pump 3 pressurizations.In case the master through the stipulated time washes operation, be with that connect to carry out will contain the clean water of washing the dirt that falls from tableware etc. discharge the outer drainage procedure of machine, again supply with the feedwater operation of clean water, from residual rinsing process and the drainage procedure that the tableware of washing agent and leftovers etc. is arranged of the rinsing of each clean nozzle 6,9 sparging water purification, so repeat 4 times whole clean operation constipation bundle.The elemental motion of above clean operation is identical with traditional table-ware washing-machine.
Because second of present embodiment is cleaned nozzle 9 as shown in Figure 8, be the curved shape that protrudes to direction of rotation, so can produce power fy at the internal face of nozzle as shown in Figure 9 to direction of rotation.Big or small available formula 1 expression of this power fy.
Fy=-(PA (sin α-sin β)+ρ QV (sin α-sin β)) (formula 1)
P: pipe internal pressure, A: sectional area, ρ in the pipe: fluid density, Q: flow,
V: flow velocity, α: inlet angle, β exit angle
Making the second rotating torques F that cleans nozzle 9 rotations is the product that this power fy and second cleans the spout radius L3 of nozzle 9, available formula 2 expressions.
F=2 * fy * L3 (formula 2)
As mentioned above, made the curved shape that protrudes to direction of rotation because second in the present embodiment cleaned nozzle 9, thereby can obtain sufficient turning moment.Therefore be located at the second spray-hole 10b that cleans nozzle 9 and just the spray angle of cleaning water can be holded up, clean to help with tableware.In other words.Past is in order to make second to clean nozzle 9 rotations and specially the spray angle of spray-hole 10b is set level, thereby has sacrificed clean efficient, and present embodiment then only needs consider to set jet angle from cleaning efficient.
When adopting above-mentioned present embodiment, to clean the quantity of spray-hole 10b of nozzle 9 constant even be located at second, and the flow of the clean water of circulation is also constant, still can improve clean efficient.And by the turning moment that further increase is rotated the second clean nozzle 9, even when having foreign matter to enter nozzle bearing 12, second situation that the rotation of cleaning nozzle 9 stops or rotating speed reduces unusually can not take place yet, can improve the reliability of table-ware washing-machine.
In conjunction with Figure 10 the present invention the 5th embodiment is described again below.1 is ablution groove among the figure, and 2 for being positioned over the plate-basket of washing in the groove 1, and 3 for cleaning pump, and 4 be heater, 5 control device for a succession of actions such as the feedwater of table-ware washing-machine, clean, rinsing, draining, drying are controlled.6 for the lower space that is equipped on plate-basket 2, horizontally rotate slightly, radius of turn is L1 first cleans nozzle.First clean be provided with on the nozzle 6 rotation identical with previous embodiment freely second clean nozzle 9, the distance that its axis of rotation departs from 6 axis of rotation is L2.Particularly, first of present embodiment is cleaned nozzle 6 as shown in figure 11, is the curved shape that protrudes to direction of rotation.And first clean nozzle 6 and second and clean a plurality of spray-hole 10a, the 10b that respectively is provided with the tableware sparging water purification in plate-basket 2 on the nozzle 9.11,12 are respectively the first nozzle bearing and the second nozzle bearing that the nozzle 6 and the second clean nozzle 9 are cleaned in axle supporting first.
The below action of explanation present embodiment.The elemental motion of its clean operation is with the aforementioned the 1st
Embodiment is omitted at this.
Because it also is the curved shape that protrudes to direction of rotation that first in the present embodiment cleaned nozzle 6, so produce the power of Fy and Fyy size to the nozzle direction of rotation at first two ends of cleaning nozzle 6.The formula 1 that illustrates among big or small available the 4th embodiment of this power Fy and Fyy is represented.The turning moment Ft that this power be multiply by in the formula 3 that draws behind the spout radius acts on the first clean nozzle 6.
