Description
Technical field
The present invention relates to a kind of home appliances, it is preferably configured to washing machine, scrubbing-and-drying unit etc., in described home appliances, in washing process, along tubulose calandria formation liquid flow, for example wash solution, flows.
Background technology
In home appliances, for example washing machine or scrubbing-and-drying unit, the tubulose calandria with independent heating tube has represented the heater of most common type, it is heated to proper temperature for the representative stage in washer operation by wash solution, and the washing agent that makes to be dissolved in wash solution can be implemented its effect.Except by temperature and washing agent role, the motion acting on the clothing being introduced in laundry wheel is also worked by the commutation campaign of laundry wheel conventionally, to realize best cleaning effect.
In the situation that the washing machine of laundry wheel axis substantial horizontal orientation, tubulose calandria is contained in laundry wheel below, but still in by laundry wheel substantially in the bucket of fully sealing, and suitable and substantially known fixture be arranged for tubulose calandria and independent heating tube thereof.Distance between bucket and the corresponding wall of laundry wheel keeps very littlely, and the solution being surrounded by bucket is located substantially in the inside of the laundry wheel with punched-type drum housing.Yet the portion of cutting off must be arranged in the residing bottom of the barrel of fixed tubulose calandria, so as to meet for tubulose calandria and at least for example, around the space requirement for the amount of the liquid (wash solution) of tubulose calandria.In bucket around this space of tubulose calandria also referred to as calandria container, for example conventionally there is the calandria container of unsymmetric structure.For security consideration, liquid, for example solution are present in the space of tubulose calandria always, even if make when washing procedure starts (now bucket is not yet filled solution in desired mode), the pipe of tubulose calandria can not burn out yet.Tubulose calandria can be described as always by solution pool around.
Frequent washing process adversely causes the calcification of tubulose calandria and much suede wadding to be accumulated in the space of tubulose calandria, described suede wadding in washing process, for example commutating in washing process may be with at a high speed by cylinder eyelet.In wash solution discharge process, this suede wadding can not remove from described space completely, because the solution of a certain minimum volume must be retained in the space of tubulose calandria always.Therefore, regrettably, not only there is harmful calcification in tubulose calandria, and suede wadding is also attached on the tubulose calandria with heating tube always, or suede wadding is in tubulose calandria deposition around, efficiency and the service life of having reduced thus tubulose calandria.
Also illustrated that home appliances, for example washing machine and scrubbing-and-drying unit can have the stream plate that is adjacent to tubulose calandria and its corresponding heating tube, to make heat radiation away from specific region.In DE7023740U, disclose this stream plate, wherein, described stream plate is not as in original prior art of considering, to be contained in the close of solution pool to be present in tubulose calandria there and the region of its heating tube.
Summary of the invention
Therefore, the object of this invention is to provide a kind of for existing home appliances (such as washing machine, scrubbing-and-drying unit etc.), for the solution in the region of tubulose calandria and its heating tube, according to this solution, the calcification of discussing and suede wadding deposition are avoided as much as possible.
According to the present invention, preferably be configured to washing machine, (described laundry wheel can be around the axis rotation of basic horizontal orientation for the laundry wheel that has of scrubbing-and-drying unit etc., and be arranged in substantially in all sides, surround laundry wheel bucket) home appliances, the tubulose calandria with heating tube the housing extending in a circumferential direction of cylinder and bucket by the region between the lower wall bottom being regarded as in, tubulose calandria at least in the operating process of home appliances by liquid, for example wash solution around, described liquid preferably can heat by tubulose calandria in the predetermined operational phase, and form and flow in liquid, and in some cases, stream plate can embed between tubulose calandria and the bottom of bucket, now can make to flow plate constructs as follows: a part for liquid stream can be stopped in the region below heating tube, and can redirect in the residing region of heating tube.
For example, because in the processing procedure in home appliances (being washing process in the situation that of washing machine), the lasting lifting of the clothes items producing by the agitator in cylinder inside makes liquid or solution flow back to by the eyelet in cylinder, thereby produce and continue to flow between drum housing and bucket, in the region of the described lasting mobile also movable heating tube at tubulose calandria, therefore, according to the present invention, this is flowing in the region of heating tube and is reinforced, and makes to be created in mobile being blocked in heating tube lower zone in the situation that there is no measure of the present invention.Therefore, the dirt in the region of the heating tube of tubulose calandria and suede wadding deposition are effectively prevented.
Show, stream panel configuration according to the present invention also makes flowing of flow velocity increase totally can flow to heating tube.This means, do not compare with there is no the situation of stream panel configuration of the present invention, the flow velocity of liquid, for example solution is larger.Therefore,, by the larger wall shearing stress between solution and the area of heating surface, suede wadding and dirt particles can be flushed away, and maybe can prevent their deposition.
For the stream panel configuration under meaning of the present invention, make to flow plate have with heating tube at least one flow effect region of at least one next-door neighbour be proved to be useful.
Under meaning of the present invention, in one is improved more specifically, stream plate all has flow effect region in the both sides of the line of symmetry of hypothesis, and it is directed that the line of symmetry of described hypothesis especially can be parallel to the rotation of cylinder.
Have been found that constructing according to the flow effect region in stream plate of the present invention, have substituting solution.
According to the first replacement scheme, can make described at least one flow effect region of flowing plate there is folding part upwards, the described folding part making progress especially forms triangular cross section.
According to the second replacement scheme, can make described at least one flow effect region of flowing plate there is edge upwards.
According to the 3rd replacement scheme, can make described at least one flow effect region of flowing plate there is deep drawn part.
Yet the present invention is designed to also exist other replacement schemes substantially, this is in the instruction of considering substantially to require and become obvious during listed example for this reason.
Stream plate itself can be connected to bucket in releasable or not releasable mode in the bottom section of bucket.If bucket is made of plastics, stream plate can for example, can not discharge and be connected to bucket in manufacture (injection moulding) process of described bucket.
The present invention also means does not need to use independent stream plate.Now, the effect of stream plate can be replicated.
If bucket is made of plastics, now, the bottom of this being made of plastics barrel just should have flow effect geometry, and as can be realized by the stream plate of independent structure, the plastics in the region of the stream plate being replicated are resistant to elevated temperatures plastics preferably.Rear a kind of measure means, heat radiation (it can suitably be set originally, to do not damage the plastics of conventional configurations) is now stood this heat load.
While constructing described flow effect geometry in the bottom at Plastic Drum, it should be noted that for this object need to provide with heating tube at least one flow effect region of at least one next-door neighbour.
Show, it is useful in the bottom of bucket, in the both sides of the line of symmetry of supposing, all constructing flow effect region, and described region is compared and had identical embodiment with the region of the substituting embodiment of the stream plate of independent structure.
If bucket is made by metal material, for example metallic plate, the bottom of bucket just should have flow effect geometry, as also can realized by the stream plate of independent structure.
In the situation that bucket is made by metal material, at least one flow effect region that can make to be close at least one setting in heating tube is a part for the flow effect geometry in the bottom of described bucket.
Also show, if flow effect region can be built into the both sides of the line of symmetry of hypothesis in the bottom of bucket, be useful herein, and described region is compared and had identical embodiment with the region of the substituting configuration of the stream plate of independent structure.Yet, should consider and have some restriction, make to use such configuration: the unallowed opening that has formed the bucket of being made by metal material in this configuration.Yet the in the situation that of fault, the heat radiation aspect that is not desirably in tubulose calandria and its heating tube has problems.
Although the present invention improves by claims dependent but backward reference independent claims, but, as long as other of claim be combined in those skilled in the art it seems be considered to be applicable to feasible, the backward reference chain initially indicating limits the instruction of overall proposition with regard to not being considered to.
Accompanying drawing explanation
Below with reference to exemplary embodiment, carry out schematically to describe in more detail the present invention.Identical Reference numeral represents same or similar parts.Accompanying drawing is described first briefly.
Fig. 1 shows the basic partial sectional view of home appliances, for example washing machine, this figure relate to laundry wheel with bucket in the heating tube that is positioned with tubulose calandria and the region of stream plate of the present invention;
Fig. 2 shows the not isomorphism type of stream plate of the present invention, wherein, the flow effect region of stream plate Fig. 2 a) in folding part by upwards, at Fig. 2 b) in by the edge that makes progress with at Fig. 2 c) in by deep drawn part, realize.
The specific embodiment
In Fig. 1, in basic the analysing and observe of home appliances, for example washing machine, there is shown according to all parts of the present invention.Therefore, laundry wheel 2 can be around axis 1 rotation of the approximate horizontal orientation of laundry wheel 2.Selected cutaway view just shows the center of rotation not in scale, and the housing 4 of laundry wheel 2 and rotation 1 Gai center are at a distance of radius R.It is directed that rotation is approximately perpendicular to the drawing of this figure.Laundry wheel 2 is surrounded by bucket 3 substantially in all sides, and described bucket 3 can receiving fluids, for example wash solution 8.Because Fig. 1 is for most important feature of the present invention, therefore, the not shown part that is present in the wash solution in laundry wheel 2.Therefore, in Fig. 1, what mainly pay close attention to is region 6, and described region 6 is between the housing 4 extending in a circumferential direction of laundry wheel 2 and the lower wall that is counted as bottom 5 of bucket 3.Have heating tube 7,7 ' tubulose calandria in this region 6, when home appliances is operated in interested mode, have heating tube 7,7 ' tubulose calandria by aforesaid liquid, for example wash solution 8, surrounded.When predetermined heat is in the stage, this liquid, for example solution in operating process by have heating tube 7,7 ' tubulose calandria heat.Because laundry wheel 2 rotates in the operating process of washing machine, therefore in liquid 8, form and flow 9, originally described mobile 9 illustrate by a plurality of arrows.Stream plate 10 embed the heating tube 7,7 of tubulose calandrias ' with barrels 3 bottom 5 between, described stream plate 10 originally have heating tube 7,7 ' the operating process of calandria in for making heat by these heating tubes 7,7 ' send away from bucket, the especially bottom 5 of bucket 3, particularly when conventionally manufacturing barrel with heat sensitive plastics economically.
Fig. 1 also shows of a plurality of agitators 11 on drum housing 4 inner sides that are arranged in laundry wheel 2.Arrow 12 illustrates with respect to shown agitator, with the wash solution that represents to be introduced into clothes items in laundry wheel and held in the operating process of washing machine, be transmitted along direction.Can find out, flow 9 directed against direction of transfer 12.Because clothing transmits by agitator 11, therefore according to the rotary speed of laundry wheel 2, clothing promotes constantly and again falls in some instances.Meanwhile, wash solution has been ladled out in the motion of clothing and agitator, so wash solution flows out from cylinder again, and flow back in the gap between barrel shell and cylinder, thereby form wash solution 8 flow 9, as shown in Figure 1.
Determine, lasting washing process can adversely cause heating tube 7, the 7 ' calcification of tubulose calandria, and causing many suede waddings to be accumulated in the space or region 5 of tubulose calandria, suede wadding can depart from clothing also by the osculum in laundry wheel when clothing significantly moves in washing process.Especially at higher temperature, this suede wadding can be in conjunction with the dirt discharging from wash solution, and on the heating tube of calandria, is deposited as very stable layer.Particularly the suede in region 5 wadding is concentrated and is also had benefited from: suede wadding can not be completely in the drain operation process of discharge wash solution 85 removes from region.By being deposited on the compounding substances that dirt on heating tube and suede wadding form, can in the operating process of tubulose calandria, cause hot polymerization collection (Warmestau), thus the service life that efficiency is had a negative impact and reduces tubulose calandria.
In order to eliminate these shortcomings, according to the present invention proposes a kind of special approach of originally not pointing out.Determine, contrary with traditional smooth configuration, stream plate 10 should be configured to have a kind of like this structure: this structure make liquid 8 flow a part of 9 heating tube 7,7 ' below region 13,13 ' in stopped, and be diverted in the region at heating tube place.Therefore, Fig. 1 shows 9 the distribution of flowing realizing by measure of the present invention.
The particular configuration of stream plate 10 also means, the region 13,13 of constriction ' help under, flow velocity increases, and flow 9 totally can be around heating tube 7,7 ' flow, this also can be by considering that the relevant flow law on foundation of the present invention basis explain.
For form the region 13,13 of constriction ', need to make to flow plate 10 have with heating tube 7 and 7 ' at least one next-door neighbour at least one flow effect region 14 or 14 '.
Obviously, stream plate 10 in the both sides of line of symmetry (not shown) of hypothesis, have respectively flow effect region 14 and 14 ', the line of symmetry of described hypothesis is especially parallel to rotation 1 orientation of cylinder 2.
Determined, aspect the realizing of stream plate, exist different replacement schemes a)-c).These replacement schemes in Fig. 2 figure part a)-c) shown in.
Figure part a) in, stream plate represents with Reference numeral 20.Be provided with flow effect region, described flow effect region is by folding part 24, the 24 ' formation making progress accordingly.This has produced the cross section of general triangular, the cross section of described general triangular can in Fig. 1, in the mode that can easily recognize, be assigned to there is flow effect region 14,14 ' the diagram of stream plate 10.Also indicated, only shown the important for the purpose of the present invention region of stream plate 20 configurations.Stream plate 20 also can be connected in releasable mode (for example, by means of screw) or in not releasable mode (for example, by rivet or bonding) barrels 3 bottom 5.If bucket 3 is made of plastics, and there is the not releasable connection of bucket, just also can in the manufacture process of bucket 3, (for example, by means of injection moulding) connect stream plate 10 or 20.Now, the plastic areas of bucket keeps flowing plate by means of adhesion.
At figure part b) in, stream plate represents with Reference numeral 30.Be provided with flow effect region, described flow effect region is by the edge making progress the accordingly 34 and 34 ' formation of stream plate.When described stream plate is positioned on bucket 3 bottom 5, has formed sharp-pointed transition, thereby produced local very strong flowing with very high speed.This is of value to and removes and take away dirt particles and suede wadding very much.Still only show the important for the purpose of the present invention region of stream plate 30 configurations herein.Feasible fixed form is selected and identical described in a) for Fig. 2.
At figure part c) in, stream plate represents with Reference numeral 40.Be provided with flow effect region, described flow effect region, by corresponding deep drawn part 44 and 44 ' formation, namely finally forms by deep-drawing.For example, described flow effect region can form by corresponding curled portion.This provides flow to affect useful configuration in the sense of the present invention, thereby dirt particles and suede wadding can be removed and take away with the degree of expectation.Still only show the important for the purpose of the present invention region of stream plate 40 configurations herein.Feasible fixed form is selected and identical described in a) for Fig. 2.
From especially according to Fig. 2 a)-c) in the different scheme of the part of described exemplary embodiment, the present invention also can be embodied as and make to flow plate itself and do not used.Now, bucket 3 bottom 5 must have flow effect geometry, this geometry corresponding to for example use according to Fig. 2 a)-c) embodiment in the resulting geometry of stream plate.Now can construct bucket by plastics or metal material or metallic plate.If select plastics as stock, selected plastics should be modified in the region of heating tube, make the heat radiation of being sent by heating tube to the plastic material of bucket, not produce serious functional lesion in the situation that of fault.If selection metal material, when copy with Fig. 2 a)-c) in the similar configuration of modification time, should guarantee not have tomography or crack to be formed in the bottom 5 of bucket.Therefore, the configuration that the selection of stave wood material should be based on possible, to form best flow effect geometry.
In addition, should also be pointed out that, the flow effect region 14,14 described in all embodiment of the present invention ' or the flow effect structure that forms thus can have heating tube 7,7 ' the whole length of tubulose calandria on or on partial-length, (in this case, should consider that tubulose calandria has the region of calcification risk especially) and extend.
