Definitions

  • the present invention relates to a spray rinsing method applicable to a washing process in a washing machine having a rotating drum, preferably with a horizontal axis and an axial loading/unloading opening, although it is also applicable to washing machines with a vertical axis rotating drum.
  • the rinsing method of the invention is aimed at providing a significant saving in water, power consumption and additives, preserving the lifetime of the motor.
  • drum rotational speeds are expressed by means of G units, where 1G is equivalent to the acceleration of gravity, i.e., the rotational speed which, according to the radius of the drum, causes a centrifugal acceleration equivalent to the acceleration of gravity at the level of the cylindrical wall of the drum.
  • Washings machines of a type provided with a washing tub capable of containing an amount of liquid, inside which a rotating drum provided with a perforated wall is assembled, are well known.
  • the drum is assembled such that it can rotate with respect to a horizontal or vertical axis and is provided with an axial loading/unloading opening.
  • An electric motor is arranged to selectively rotate the drum in any of the two directions at variable speeds.
  • the tub has a liquid inlet provided with controlled valve means for introducing an amount of liquid into the tub and a liquid outlet provided with controlled valve means for allowing a drainage of the tub.
  • a bleaching agent could be added to the rinsing water, in one or more intermediate rinsing cycles, if any, only water could be used, and in a final rinsing cycle a softening agent could be added to the rinsing water.
  • Patent US-A-3811300 proposes reducing the number of rinsing cycles by means of a washing machine with a washing tub, a horizontal axis rotating drum with an axial loading/unloading opening, and spray nozzles installed in a door of the loading/unloading opening and directed for the purpose of spraying clean water on the load of clothes located on the inner wall of the drum.
  • the operation is as follows. After one or more washing cycles, a rinsing cycle is performed which consists of rotating the drum at a relatively high speed so that the load of clothes remains stationary with respect to the wall of the drum and continuously spraying clean water on the load of clothes rotating inside the drum.
  • Patent DE-A-4013450 to Licentia Patent-Verwaltungs-GmbH, discloses a rinsing process applied to a rotating drum washing machine, provided with a device for spraying water into the drum and controlled by a program. The process corresponds to the stages depicted in the graph of Figure 5 , where "Vg” is the drum rotational speed in rpm, "Sa” is the rinsing liquid supply and "t” is the time.
  • a rinsing phase II during which the drum is rotated at a speed of approximately 80 rpm (slightly greater than 1G), such that the clothes contained in the drum adhere to the inner surface thereof, forming a ring, and the rinsing water is continuously sprayed on the clothes from the center of said ring.
  • This spraying phase at the speed of 80 rpm is interrupted for periods in which the drum is rotated at a high speed, clearly greater than the washing rotational speed, to expel the water from the clothes by centrifugation.
  • This high speed can alternate periods at a speed of 1000 to 1400 rpm with periods at a speed of 200 to 600 rpm.
  • the clothes When, in correspondence with the drum rotational speed, the clothes are saturated due to having reached the limit in their capacity to absorb water, the excess water falls in the form of a bath into the tub.
  • the water in the tub can be detected and used as a signal for a subsequent development of the program, for example, to interrupt the spraying of water and perform a tumbling of the clothes at 50 rpm to redistribute the clothes in the drum.
  • a drawback of this process of the cited patent DE-A-4013450 is that the tumbling of the clothes at 50 rpm is performed when it is considered that such clothes are already saturated with water. In other words, after tumbling the clothes at 50 rpm, no more water is added and the process passes directly to the centrifugation phase at speeds ranging from 200 to 1400 rpm.
  • Patent DE-A-4115776 to Licentia Patent-Verwaltungs-GmbH, describes a rinsing and centrifugation method applicable to a washing machine with a washing tub, a horizontal axis rotating drum with an axial loading/unloading opening, and a spraying device for spraying rinsing liquid into the drum.
  • the Licentia method comprises, as shown in the graph of Figure 6 (where "Vg” is the drum rotational speed in rpm, “Sa” is the rinsing liquid supply and “t” is the time), after the washing process I, performing an impregnation and centrifugation process II consisting, first of all, in draining the washing liquid from the tub and performing a centrifugation of the load of clothes at a speed of approximately 1000 rpm. The speed is then reduced to approximately 100 rpm (greater than 1G) and, when the drum has reached this speed, a certain amount of water is sprayed into the drum and on the load of clothes which remains stationary with respect to the wall of the drum.
  • the drum is then taken to a centrifugation speed of approximately 800 to 1000 rpm to extract the water by the centrifugal force generated.
  • a redistribution operation III for redistributing the load of clothes is performed, reducing the speed of the drum to a tumbling speed and then spraying a larger amount of water to detach the load of clothes which has remained adhered to the inner wall of the drum due to the effect of the centrifugal force.
  • the speed of the drum is again increased to approximately 800 to 1000 rpm and then additional impregnation and centrifugation operations are performed in the same manner.
  • Patent EP-A-1254283 describes a method for rinsing a load of clothes in a washing machine having a perforated drum rotating about an axis and capable of receiving the load of clothes therein, and a spraying device capable of spraying water into the rotating drum.
  • the Dyson method as shown in Figure 7 (where "Vg” is the drum rotational speed, "Sa” is the rinsing liquid supply and "t” is the time), comprises the following stages. Firstly, the drum is rotated at a first rotational speed V2 sufficient to keep the load of clothes stationary with respect to the rotating drum.
  • a volume A of rinsing water is introduced into the rotating drum through the spraying device, such that the rinsing water is sprayed on the load of clothes, and then the drum rotational speed is increased to a second rotational speed V3 sufficient to centrifuge a significant proportion of the rinsing water out of the load of clothes.
  • the impregnation and centrifugation cycle C is preferably repeated several times.
  • the Dyson method has the drawback of not assuring a complete and homogeneous impregnation of the load of clothes during the first impregnation and centrifugation cycle C, because once the drum has reached the medium rotational speed V2 and the load of clothes has been stationarily applied to the inner wall of the drum, the distribution of the load of clothes will substantially not change, maintaining areas with a higher degree of accumulation and areas with a lower degree of accumulation on the inner wall of the drum until the speed of the drum reaches a value less than 1G again, which is not expected until the end of the entire rinsing process made up of the several repeated impregnation and centrifugation cycles C.
  • the Dyson method is very similar to the one discussed above in relation to the cited Licentia patent DE-A-4115776 , and has the same drawback referring to the low water absorption capacity of the load of clothes after it has been subjected to an intense compression against the wall of the drum during the previous centrifugation operation at high speed, added to the non-homogeneous impregnation due to the irregular distribution of the load of clothes. Furthermore, the Dyson method is also unsuitable for performing an application of additives with the rinsing water due to the incapacity to assure the complete and homogeneous impregnation of the load of clothes.
  • the cited Dyson patent also claims that the volume A of rinsing water introduced in the spraying stage is smaller than the volume required to saturate the load of clothes, such that substantially all the rinsing water is absorbed inside the load of clothes.
  • the volume A of rinsing water introduced in the spraying stage is smaller than the volume required to saturate the load of clothes, such that substantially all the rinsing water is absorbed inside the load of clothes.
  • the amount of water sprayed on the load of clothes is much smaller than the volume required to saturate it, this will involve the need for a larger number of spraying and centrifugation cycles to perform the rinsing, with an increase in the time required, a higher energy consumption and a greater wear of the motor.
  • the precise volume of water required to saturate a load of clothes will depend, among other factors, on the amount of clothes and on the type of fabric.
  • the problem to be solved is how to assure that this "precise" volume of water required to saturate a load of clothes and which is supplied by spraying on the load of clothes during an impregnation stage in a rinsing cycle is effectively absorbed completely and in a uniform and homogeneous manner by the load of clothes before proceeding to a centrifugation stage.
  • the present invention contributes to solving the previous problem by providing a spray rinsing method applicable to a clothes washing machine provided with a drum having a perforated wall capable of receiving a load of clothes therein, a controlled motor for rotating said drum about an axis in any of the two directions at variable speeds, and a spraying device capable of introducing rinsing liquid into the drum.
  • the method generally comprises, after a washing and drainage cycle, rotating the drum at a medium rotational speed (greater than 1G) sufficient to keep the load of clothes stationary with respect to the rotating drum but insufficient to cause an extraction of liquid out of the load of clothes by the centrifugal force generated, impregnating the load of clothes by spraying an amount of said liquid into the drum and on the load of clothes by means of said spraying device while the drum rotates at said medium rotational speed, and then increasing the drum rotational speed to a high rotational speed sufficient to extract a significant proportion of the liquid out of the load of clothes by the centrifugal force generated.
  • a medium rotational speed greater than 1G
  • the method of the present invention is characterized in that it comprises performing said impregnation of the load of clothes with said amount of liquid by means of a plurality of spraying steps for spraying the liquid on the load of clothes while the drum rotates at said medium rotational speed, and carrying out, between every two of said spraying steps, a tumbling step for tumbling the load of clothes with the interruption of the spraying, wherein each tumbling step comprises reducing the drum rotational speed to a low rotational speed (less than 1G) suitable for performing a tumbling of the load of clothes inside the drum.
  • a substantially complete and homogeneous impregnation of the load of clothes with the amount of the liquid is obtained before increasing the drum rotational speed to said high rotational speed.
  • the amount of liquid sprayed is a predetermined amount which is established according to the amount and type of clothes to be treated, and said predetermined amount of liquid is supplied in successive fractions of liquid in the spraying steps alternated with tumbling steps until reaching a highly uniform and homogeneous impregnation.
  • the rinsing liquid can be supplied in successive doses in the spraying steps until it is considered that the total amount provided is sufficient for a rinsing stage, for example when the state of saturation of the clothes has been reached, which can be detected by the presence of spraying liquid at the bottom of the tub according to a procedure of the state of the art.
  • the method of the present invention further allows an efficient application of additives together with the rinsing liquid, which is generally water, as a result of the fact that it is assured that the rinsing liquid will completely and homogeneously impregnate the load of clothes.
  • the drum is maintained stopped or rotating at any rotational speed equal to or less than the medium rotational speed for a time period considered suitable for allowing the action of said additive.
  • the drum can be rotated at a very low rotational speed, preferably comprised between zero and the low rotational speed, including one or more reversals in the rotational direction of the drum to tumble the load of clothes.
  • a very low rotational speed preferably comprised between zero and the low rotational speed, including one or more reversals in the rotational direction of the drum to tumble the load of clothes.
  • These tumbling stages at the very low rotational speed can be alternated or combined with one or more rotation stages at the medium rotational speed and/or with one or more stopping stages.
  • the spray rinsing method is described below, which method is applicable to a clothes washing machine of a known type (not shown), having a drum 10 ( Figures 2 and 3 ) with a perforated wall capable of receiving a load of clothes 12 therein, a controlled motor for rotating said drum 10 about an axis in any of the two directions at variable speeds, and a spraying device capable of introducing rinsing liquid into the drum.
  • the drum 10 preferably has a substantially horizontal axis of rotation and an axial loading/unloading opening, and said spraying device includes one ore more spraying nozzles installed, for example, in a door of the mentioned loading/unloading opening and directed towards the inner wall of the drum.
  • the rotational speeds and directions of the drum as well as the supplies of water or rinsing liquid through the spraying device are generally controlled with respect to time by a pre-programmed or programmable control device.
  • the method of the present invention comprises, first of all and generally after a washing operation, impregnating a load of clothes 12 contained in the drum 10 by spraying a predetermined amount of said liquid A into the drum 10 and on the load of clothes 12 by means of the spraying device while the drum rotates at a medium rotational speed V2 (greater than 1G and generally less than 20G) (see also Figure 3 ) sufficient to keep the load of clothes 12 stationary with respect to the rotating drum 10 but insufficient to cause an extraction of liquid out of the load of clothes by the centrifugal force generated by the rotation, and then increasing the drum rotational speed to a high rotational speed V3 (generally greater than 50G and up to 300G or more) sufficient to extract a significant proportion of the liquid out of the load of clothes by the centrifugal force generated.
  • V2 greater than 1G and generally less than 20G
  • the mentioned predetermined amount A of liquid will preferably be an amount of liquid equal to or slightly less than the amount of liquid which is considered hypothetically necessary to saturate the load of clothes.
  • the predetermined amount A of liquid for impregnating the load of clothes 12 is not provided all at once, but rather it is divided into fractions A1, A2,...An of liquid which are supplied by means of respective spraying steps for spraying on the load of clothes 12 while the drum rotates at said medium rotational speed V2, and between every two of said spraying steps a tumbling step for tumbling the load of clothes is carried out for a time period in which the spraying is interrupted.
  • Each tumbling step comprises reducing the drum rotational speed to a low rotational speed V1 (less than 1G) (see also Figure 2 ) suitable for performing a tumbling of the load of clothes inside the drum and maintaining this low rotational speed V 1 for a predetermined period.
  • V1 low rotational speed
  • Each tumbling step at said low rotational speed V1 preferably includes one or more reversals in the rotational direction of the drum indicated in the graph of Figure 1 as +V1 and -V1.
  • an additional tumbling step can be performed after spraying the last fraction of liquid An and before the corresponding centrifugation stage N.
  • the impregnation and centrifugation cycle C can be repeated a number of times until achieving a satisfactory rinsing.
  • One embodiment contemplates performing from 2 to 6 complete spraying and centrifugation cycles C for a rinsing, depending on the amount and type of clothes in the load of clothes, the quality of the water, the detergent used in the previous washing operations, etc.
  • the method comprises performing a detachment operation D consisting of a supply of liquid Ad into the drum 10 by means of the spraying device while the drum is rotated at the low rotational speed V1.
  • This supply of liquid Ad increases the weight of the clothes and contributes to the latter being detached from the inner wall of the drum 10 after the centrifugation.
  • the amount of liquid Ad sprayed during the detachment operation D and which will be absorbed by the load of clothes can be considered as one of the fractions of liquid to be deducted from the fractions A1, A2,...An of the following impregnation stage M.
  • the sum of all the fractions A1, A2,...An of liquid used in the different spraying steps of an impregnation and centrifugation cycle C is equal to the predetermined amount A of liquid sprayed in the impregnation stage M.
  • the liquid used can be water alone or water with additives.
  • the fact of supplying the predetermined amount A of liquid in fractions A1, A2,...An allows, for example, adding one or more additives to the water in one or more of the fractions A1, A2,...An of liquid selected.
  • a bleaching agent could be added to the water of the corresponding fractions A1, A2,...An
  • a neutralizing or softening agent could be added to the water of the corresponding fractions A1, A2,...An.
  • the total amount of liquid to be sprayed in the impregnation stage M is not known beforehand and is determined during the cycle when it is detected that the load of clothes is saturated.
  • the state of saturation of the load of clothes can be detected, for example, when after several spraying and tumbling steps a detector detects the presence of an amount of the liquid from the spraying at the bottom of a tub inside which the drum rotates, which indicates that the load of clothes is incapable of absorbing more liquid because it is saturated, and the excess liquid falls to the bottom of the tub.
  • the graph of Figure 4 (where "Vg” is the drum rotational speed, “Sa” is the rinsing liquid supply and “t” is the time) is a variant of the graph of Figure 1 including a first rinsing cycle C with an impregnation stage M including the application of additives, during which a predetermined amount A of liquid composed, for example, of water with one or more additives, is supplied.
  • a predetermined amount A of liquid is supplied by means of several spraying steps for spraying fractions A1, A2,...An of liquid while the drum rotates at the medium rotational speed V2.
  • this variant of the method comprises maintaining the drum stopped or rotating at one or more rotational speeds comprised between zero and the medium rotational speed V2 for a time period T considered sufficient or suitable for allowing the action of the additive or the additives impregnating the load of clothes together with the water.
  • the cycle C ends with a centrifugation stage N in which the liquid is substantially extracted from the load of clothes by the centrifugal force generated by the rotation of the drum at the high rotational speed V3.
  • the mentioned period T comprises first of all a tumbling of the impregnated load of clothes inside the drum at a very low rotational speed, less than the low rotational speed V1, including one or more reversals in the rotational direction of the drum to perform a light-duty mechanical work, followed by a rest period during which the rotation of the drum is stopped, and by a period of rotation at the medium rotational speed V2 during which the load of clothes remains stationary with respect to the wall of the drum, before the centrifugation stage N.
  • the example of Figure 4 is merely illustrative, and variations with respect to the modes of rotation of the drum to be performed during the time period T for allowing the action of the additive or additives depending on the type of fabric and the class of additives will readily occur to a person skilled in the art.
  • the drum could remain stopped or could remain rotating at a constant rotational speed less than the low rotational speed V 1 or comprised between the low rotational speed V1and the medium rotational speed V2, or alternatively it could remain rotating at a rotational speed less than the low rotational speed V1 including reversals in the rotational direction.
  • two or more of the modes of rotation shown in the period T of Figure 4 could be combined in a different order.
  • the number of spraying steps for spraying fractions A1, A2,...An of liquid in each impregnation stage M will be determined by different factors, such as the type of fiber and/or fabric from which the load of clothes is formed, or the hardness of the water, and will generally be from 2 to 6, although it is not ruled out that it can be more than six.
