Description

1 Method and Apparatus for &g the Contents of a Container 2337274 The
invention relates to a method and apparatus for agitating the contents Of a container. Particularly, but not exly, the invention relates to an improved washing machine.
Conventional washing machines ly ag textile altcles within a drum m the presence of water and detergent so dirt is released from the fibres of the textile articles into the water. The agitation is mased, in the case of front- loading washing machines. by the rotation of the drum a horizonud axis so that the textile articles tumble over one another and rub ag other. The rotational speed of the drum is limited since, if the speed is too hg^ the textile articles will merely stick to the inside walls of the drum. under I&M - -a without being agitated with m%xtct to the drum or with respect to one - amount of agitation which can be applied to the textile articles is therefore 1 An object of the invention is therefon to apparatus for agitating the contents of a container which, in the context of a wR machine, applies more agitation to those contents than known machines withoqko pwumbmg to the disadvantages of those known machines. A fir object of W# invention is to provide a washing machine which is capable of washing textUe,es more quickly than known washing machines. A f object of the mvmmi_ 1. is to provide a washing machine which is capable of washing textile articles to standard of cless in a given time than known washing machines.
2 ne invention des apparatus. for containing and agitating the contents thereof, comprising a drum rotatable about.an axis and drive means for rotating the drum about the axis, characterised in that the drum is made up of at least two rotatable portions and the drive m are capable of rotating the rotatable portions at different speeds andlor in dif%ze t directions with respect to one another. The invention also provides a method of agitating the contents of a container utilising apparatus according to any one of the preceding c, comprising the step of rotating the drum about the axis, characterised, m that, during at least part of the said step of rotating the drum about the axis, the rotatable portions of the drum are rotated at different speeds andlor in different directions with respect to one another Providing a drum which is made up of at least two rotatable portions and drive means capable of driving the rotatable portions at different speeds andlor in different directions with respect to one another means that the contents of the drum can be constantly agitated at a high rate. In the case of a dnnn having a horizontal or inclined axis, the movement of one portion of the drum, relative to another portion prevents the contents of the drum from becoming stuck to the wall of the drum The contents of the drum, are constantly tumbled in a highly agitated manner and, when the apparatus is a washing machine, dirt is therefore released from the textile articles at a higher rate than in current machines. This means that the contents of the washing machine are clmed to a desired standard much quicker than has previously been achievable.
In a preferred embodiment, the drum consists of two essentially cylindrical portions. Preferably, the portions are capable of being driven at the same speed in opposite directions. This maximises the agitation of the contents of the drum and, in the context of a washing machine, allows textile articles to be cleaned to a specific standard very quickly or, if preferred, to a very high standard in a specific time. In alternative embodiments, the rotatable portions can be driven at different speeds in the same 3 on or at diff=nt in opposite ons. It is also possible to achieve the m= effect by retaining one rotatable portion stationary and rotating the other portion in either direction.
Other objects and advantages of the inon will become apparent ft= the following description of a number of pref aU of which are given for the purposes of illustration only and are not Men to be limiting.
In the drawings:
Fig= 1 is a schematic paspective view of apparatus a=nflng to a first embodiment of the invention; Figure 2 is a front view of the ims, of Figure 1 in use and for part of a washing machine; Fig= 3a is a front view of the dri forming part of the apparatus of Fig= 2; Figure 3b is a side view of the driving xgff of Figure 3a; Figure 4 is a schematic perspective vow of apparatus according to a second embodiment of the invention; Fig= 5 is a front view of the appm of Figure 4 in use and forming part of a washing machine; Figures 6ab and c are schematic pm views, similar to Figure 1, of apparatus according to third, fourth and fifth of the invention; and Figure 7 is a front view of a seventh mnb of the invention.
AW 4 Apparatus according to the invention is illustrated in Figure 1. Essentially. the apparatus 10 consists of a cylindrical drum 12 mounted rotatably about an axis 14. The drum 12 is made up of two s" rotatable portions 16a, 16b, each consisting of a cylindrical wall and a circular end wall. The rotatable portions 16a. 16b are individually mounted so as to be rotatable about the axis 14 and are each driven by drives (see Figures 2 and 3). The drives am ar=ged and adapted so that each rotatable portion 16a. 16b can be rotated about the axis 14 at a speed or in a direction which is different from that of the other rotatable portion. 1n the illustrated embodiment, the rotatable portion 16a can be rotated in the direction of arrow 18a. whilst the rotatable portion 16b can be rotated at the same speed in the direction of arrow I gb.
Figure 2 shows the embodiment shown in Figure 1 as applied to the field of washing machines. The drum 12 is here located in a tub or tank 20 which also contains water and detergent. Textile articles 22 to be washed are contained within the dnun 12 which has perforations (not shown) in order to allow water to flow into the drum 12 from the tank 20 and vice versa. There is no need for the rotatable portions 16a, 16b to be sealed against one another since the flow of water into and out from the drum 12 is acceptable. Two separate dr ives 24a, 24b are positioned above the rotatable portions 16a, 16b in order to drive, independently of one another, the said rotatable portions 16a, 16b. The drives 24a, 24b will be described in more detail below.
When the drives 24a, 24b are activated, rotatable portion 16a is driven by drive 24a in the direction of arrow 18a and rotatable portion 16b is driven by drive 24b in the direction of arrow 18b. The rotatable portions 16a.. 16b thus rotate about the axis 14 at the same speed but in opposite directions. The textile articles 22 contained within the drum 12 are agitated as the rotatable portions 16a. 16b rotate. The textile articles 22 are continually prevented from, suc)dng to the wall of either of the rotatable portions 16a, 16b by virtue of the fact that other articles are being rotated in the opposite on by the other rotatable portion 16b, 16a. llese other articles pull the said articles 22 from the wall of the rotatable portion 16a. 16b in which they are contained. The s of on of the rotatable portions of the appw can therefore be higher than could be achieved in known wa machines and this allows the achievable degree of agitation to be higher as well. eving a hi degree of agitation means that a desired degree of cleanliness can tved in a shorter period of time than has previously been possible. Alternatively, a wg machine can now become capable of achieving a higher standard of cle&Wi s in a give period of time than has previously been thought possible.
One of the drives 24a, 24b is illustrated in Egures 3a and 3b. It will be appreciated that the drives 24a, 24b illustrated in FWm 2 can be identical to one another. For this reason only one drive is illustrated hem Odwr drive means will be immediately apparent to a skilled reader. As can be sew from Figures 3a and 3b, the drive consists of a motor 30 having a shaft 32 cw a AM toothed wheel 34. A chain 36 or other linked member engages the first toothed; 34 and also a second toothed wheel 38 fixed to a rotatable shaft 40 which is mouMd to the casing or support structure of the washing machine. The shaft 40 also ca a third toothed wheel 42. the teeth 44 of which are designed to engage with the of a chain 46 or other linked member arranged around the periphery of one rotatable portions 16a, 16b. When the motor 30 is operated, the shaft 32 rotamng the first toothed wheel 34 to rotate.
This drives the chain 36 which eau drmd toothed wheel 38 to rotate and, in turn, the third toothed wheel 42. Plof the third toothed wheel 42 forces the rotatable portion to which the drive is to rotate about the axis 14. The direction of rotation of the rotatable determined by the direction of rotation of the motor. whereas the speed of 05-0f the rotatable portion is determined not 6 only by the s of the motor but also by the configuration of the too wheels. Ite speed of on of the rotatable portions can thus be selected at will.
It will be appimiated that the toothed wheels and chains or linked members can be replaced where appropriate by pulleys and drive belts. If a drive belt is used to drive the rotatable portion itself, the drive belt may best be wrapped around a pulley located onr concentric with the axis 14 as shown in Figure 1.
A second embodiment is illustrated in Figure 4. In this embodiment, the drurn 120is made up of separate rotatable portions 160a, 160b, 160c. Each of the rotatable portions 160a, 160b, 160c has a cylindrical wall and the outermost portions 160a, 160c also have circular end walls so that the cylindrical drum 120 is essentially closedL Drive means ar to those shown in Figure 3 are provided (although not shown) in order to rotate each rotatable portion 160a, 160b. 160c about the axis 140. Outermost rotatable portions 160a and 160c are each rotatable in a first on, whereas the central rotatable portion 160b is rotatable m the opposite direction, but at the same speed. The agitation provided to the contents of the drum 120 is once again When this arrangement is applied to a washing machine as shown in Figure 5, the.. on provided to the textile articles 220 contained within the drum 120 is significantly higher than that which can be achieved using current arrangements. As before, the dnun 120 is located within a tank 200 containing water and detergent in order that the textile articles 22 are cleaned. In this arrangement, however, the drum 120 is motinted within the tank 200 about an inclined axis 140 instead of a horizontal axix.
7 It will be appreciated that the described above can be adapted m order to achieve the sarne effect. particularly with regard to the respective speeds and directions Of the rotatable Portions. MustlatiOnú of alternative arrangements are given in Figums 6a. 6b and 6c. In Figure 6a. the role portions are shown rotating in the same direction but at different 5. In ftm 6b, the rotatable portions are shown rotating at dillbrent speeds but in opposite ffirmtions. In Fig= 6c, one rotatable portion is shown as being held stataionary w other rotatable portion rotates. In all three cues, there is relative rotation bet dw rotatable portions so that the effect of producing increased agitation of tibi of the drum is achieved. It will be appreciated that the a nrA, in Fig= 6 are also applicable to drums consisting of three or even more ro Pomons.
A ftuTher embodiinent of a washing "i according to the invention is illusd in Figure 7. In this embodiment the 300 consists of a first rotatable portion 502 having a first cylindrical portion 5" a second cylindrical portion 502b. The - - JC diameter of the second cylindrical puemm- 502b Ls a little larger than that of the fust cylindrical portion 502a. Located die second cylindrical portion 502b is a second rotatable portion 504 whom corresponds to that of the first cyiffidrical portion 502a of the first rotatable pottW-MI 'Me diameter of the second cylindrical portion 502b of the first rotatable 502 is sufficient to allow there to be some clearance between it and the 0,d al rotating with t to one portions 502, 504 to rotate with to 0 rotatable portions 502, 504 to close 1W_ Aw- &I portion 504 when the two portions are g ring 505 which allows the rotatable to one another is provided between the take up any tolerances therebetween.
8 The rotatable portions 502, 504 are each driven by a drive -5% which consists of a motor -508 having a shaft 510 carrying a pulley 512. A drive belt 514 drives a second pulley 516 which is fixed to a shaft 518 on which the respective rotatable portion is mounted. The shaft 518 are preferably mounted concentrically with the inner shaft carrying the second rotatable portion In this arrangement, as before, the first rotatable portion is located within an external tank 519 which contains the water and detergent required to wash the textile articles 520 contained within the drum 500. Naturally, drainage means am required to be provided in order to allow water to be drained from the tank 519 after washing is completed and during spiming.
The apparatus descri-bed above can be used in the following manner. Articles to be washed are placed inside the drurn and water is introduced in a known manner either at the required temperature or else at a reduced temperature and subsequently heated to the required temperature. At the start of the washing cycle detergent is introduced to the drum, once again in a known manner. The rotatable portions are then rotated by the drive means so that the speed and /or direction of rotataion of one of the rotatable portions is different from that of an adjacent rotatable portion. When there are two rotatable portions, the portions can be rotated at different speeds in the same direction. at the same speed in opposite directions, or at different speeds in opposite directions. Alternatively. one portion can be held stationary whilst the other portion rotates. The s of rotation of the rotating portion can be increased above the normal speed of rotation of washing machine drums during the washing cycle, which would not normally exceed 50 rpm. Even at speeds of rotation far in excess of 50 rprri, the contents of the drum according to the invention do not stick to the wall of the drum and therefore the agitation applied to the said contents can be greatly increased.
9 it is desired to rinse the articles contained within the drurn, the washing water is drained from the drum in a known manner and clean water is introduced thereto. The rotatable portions continue to be r in the same manner as that during washing in order to maintain a high level of agitation of the textile afficies. After rinsing, the rotatable portions are rotated at the mw speed and m the same direction m order to spin excess water from the textile at in the way. The rotatable portions may be fixed together at this point in to ens= that there is little or no relative anovernent between the rotatable portions g spinning. If this fixing occurs, all but one of the drives may be shut off so dW &U or both portions are driven by a single drive. Alternatively, the drives may be e so that all or both rotatable portions are driven in the same direction and at the m= speed during spinning with any minor differences in speed being kept under m m nuel merely by the presence of the contents of the drum. With the increased agitation of c contents of the drum, it is envisaged that the duration of a normal washing cycle currently lasting about 90 minutes can be reduced by about half, possibly more, wMm there being any reduction in the standard of cleanliness to which the articles are cl The apparatus of the invention is not U to washing machines in its application and can be advantageously applied to tus m winch the contents of a container requires to be agitated to a b degree and where a shortening of the duration of the agitation would be an Or. Furthermore, variations of the apparatus bed above are inten to be included within the scope of the invention. For example, the shape of need not be cylindrical and spherical and ovoid drums are envisaged. The ro portions may also be arranged so that they are not generally similar to one m For example, in a cyadrical drim one portion may make up the cylindrical wad drum whilst another portion may make up a circular end wall of the drunt These and other variations will be apparant to a sidUed reader.
