Description

Technical Field

[0001] The present invention relates to a laundry care device with a control device. Background Art

[0002] When loading clothes into the drum of a conventional laundry care device, it is often impossible to ensure that all areas of the clothes can be evenly and optimally cleaned. Because, for example, due to the movement of the drum and the reduction of the washing liquid flow rate, the concentration of the laundry care substance in the clothes core is often not high enough. Especially when the concentration of the laundry care substance in the washing liquid is reduced due to a large amount of fresh water, the problem is more serious.

[0003] EP2348151A1 describes a method of supplying washing liquid to an alkali container and then activating a circulation device to achieve effective mixing of the clothes and the washing liquid. Summary of the Invention

[0004] The basic task of the present invention is to provide a laundry care device that ensures effective laundry care for all areas of the clothes received in the drum.

[0005] The above task is solved by the subject matter with preferred technical solution features. Advantageous embodiments are the subject matter of the alternative technical solutions, the description and the drawings.

[0006] According to a first aspect, the object of the present invention is solved by a laundry care device, which comprises: a flushing housing for receiving a laundry care substance; an alkali solution container for receiving a washing liquid, wherein the alkali solution container is fluid-technologically connected to the flushing housing; a fresh water supply device configured to supply fresh water to the flushing housing and convey the laundry care substance received in the flushing housing together with the fresh water into the alkali solution container; a laundry drum for receiving laundry, wherein the laundry drum is arranged in the alkali solution container; a drum drive device for rotating the laundry drum; and a control device, which is control-technologically connected to the fresh water supply device and the drum drive device, wherein the control device is configured to activate the fresh water supply device during a supply period to supply a predetermined partial amount of fresh water into the flushing housing and convey the laundry care substance received in the flushing housing together with the predetermined partial amount of fresh water into the alkali solution container, wherein the control device is configured to activate the drum drive device during the supply period to rotate the laundry drum at a predetermined ejection rotational speed and move the predetermined partial amount of fresh water supplied in the alkali solution container by the rotating laundry drum and dissolve the laundry care substance received in the fresh water, thereby obtaining a washing liquid, wherein the predetermined ejection rotational speed corresponds to the rotational speed at which the force acting through the rotating laundry drum, in particular the centrifugal force, is large enough to reduce the entry of fresh water into the laundry received in the laundry drum and / or expel fresh water from the laundry.

[0007] The technical advantage achieved thereby is that a washing liquid in which the laundry care substance is dissolved is obtained in the alkali solution container, wherein the washing liquid has a high concentration of the laundry care substance.

[0008] This is achieved in that the laundry care substance required for the laundry care process and introduced into the flushing housing is not flushed into the alkali solution container by the total amount of fresh water required for the laundry care process, but only a predetermined partial amount of fresh water flushes the laundry care substance into the alkali solution container during the supply period, so that after the laundry care substance is dissolved, due to the smaller amount of liquid, the concentration of the laundry care substance in the washing liquid is higher.

[0009] Here, the predetermined partial amount of fresh water supplied during the supply period is less than the total amount of fresh water required for the laundry care process. In particular, the predetermined partial amount of fresh water supplied during the supply period is not sufficient to completely moisten the laundry received in the laundry drum.

[0010] In order to prevent a correspondingly small predetermined amount of fresh water from being completely or mostly absorbed by the laundry in the laundry tub, the laundry tub rotates at a predetermined ejection rotational speed during the supply period, at which rotational speed the force acting on the fresh water due to the movement of the laundry tub and / or the centrifugal force acting on the laundry tub is large enough such that the supplied amount of fresh water cannot or can only slightly reach the laundry in the laundry tub, or the centrifugal force acting on the laundry in the laundry tub is large enough to ensure that the fresh water present in the laundry is ejected from the laundry again.

[0011] Thereby, it is ensured that the predetermined amount of fresh water supplied during the supply period (which is anyway small) is not absorbed by the laundry, but is used to dissolve the laundry care substance carried by the fresh water. The rotation of the laundry tub at the ejection rotational speed causes the supplied fresh water to move violently within the lye container, thereby promoting the dissolution of the laundry care substance in the predetermined amount of fresh water by the provided mechanical energy. Thus, even if the supplied amount of fresh water is relatively small, a favorable dissolution of the laundry care substance can be achieved, and a high-concentration washing liquid can be provided after the supply period.

[0012] The correspondingly high-concentration washing liquid can subsequently be supplied to the laundry in the laundry tub, and in particular, particularly effective laundry care can be ensured in the laundry core of the laundry. For this purpose, no additional components, such as valves, are required, but dissolution and mass transfer are carried out only by the movement of the laundry tub and convection in the washing liquid.

[0013] In particular, the control device is configured not to activate the optionally present pump for circulating and pumping the supplied amount of fresh water during the supply period to prevent the supplied amount of fresh water from being adsorbed by the laundry.

[0014] The laundry care device can be understood as a device for caring for laundry, such as a washing machine or a washer-dryer. In particular, such a laundry care device can be understood as a household laundry care device. In other words, such a laundry care device is used in household management and processes laundry in normal household quantities.

[0015] In an advantageous embodiment, the predetermined amount of fresh water supplied to the lye container by the fresh water supply device during the supply period is less than the total amount of fresh water required to moisten the laundry received in the laundry tub, wherein the supplied predetermined amount of fresh water is in particular selected such that the laundry received in the laundry tub is not completely moistened.

[0016] The technical advantage achieved thereby is that the predetermined amount of fresh water is small enough to ensure a relatively high concentration of the laundry care substance after dissolution of the laundry care substance.

[0017] In particular, the predetermined partial amount of fresh water supplied during the supply period is between 1 liter and 15 liters, in particular between 2 liters and 4 liters.

[0018] In particular, the predetermined partial amount of fresh water supplied during the supply period ensures that the fresh water level in the lye container reaches the lowermost edge of the laundry tub received in the lye container.

[0019] In an advantageous embodiment, the expulsion speed is between 30 revolutions per minute and 500 revolutions per minute, in particular between 40 revolutions per minute and 150 revolutions per minute.

[0020] The technical advantage achieved thereby is that the expulsion rotational speed advantageously ensures that the supplied partial amount of fresh water is not absorbed by the laundry received in the laundry tub, but can effectively move in the lye container by the rotation of the laundry tub, thereby dissolving the laundry care substance.

[0021] In an advantageous embodiment, the laundry care device has a heating element for heating the washing liquid received in the lye container, wherein the control device is connected to the heating element in a control-technical manner, and wherein the control device is configured to activate the heating element during the supply period to heat the fresh water and / or to activate the heating element after the supply period to heat the washing liquid.

[0022] The technical advantage achieved thereby is that the dissolution of the laundry care substance can be improved by heating the fresh water or the washing liquid.

[0023] In an advantageous embodiment, the laundry care device has a liquid level sensor for detecting the level of the washing liquid in the lye container, wherein the control device is configured to activate the heating element when the detected level of the washing liquid exceeds a minimum level threshold.

[0024] The technical advantage achieved thereby is that when the heating element is activated, it is ensured that there is sufficient washing liquid in the lower region of the lye container to prevent the heating element from running dry.

[0025] In an advantageous embodiment, the control device is configured to activate the tub drive device when the heating element is activated, so that the washing tub rotates at a speed lower than the maximum tub speed to ensure that the heating element is covered by the washing liquid.

[0026] The technical advantage achieved thereby is that the maximum tub speed determines an upper limit value, and if this upper limit value is exceeded, the washing liquid or fresh water moved by the rotation of the laundry tub will move so violently that it is no longer ensured that the heating element is covered by the washing liquid. Therefore, by limiting the tub speed to a value lower than the maximum tub speed, it can be ensured that the heating element is sufficiently covered by the washing liquid, thereby preventing the heating element from running dry.

[0027] In an advantageous embodiment, the lye container has a discharge opening and a supply element, and the laundry care device has a pump which is fluid-technically connected to the discharge opening and the supply element and is configured to pump the washing liquid out of the discharge opening and to re-supply the pumped washing liquid to the lye container through the supply element in order to achieve a circulating pumping of the washing liquid, and the control device is configured to activate the pump after a supply period in order to achieve a circulating pumping of the washing liquid.

[0028] The technical advantage achieved thereby is that, after the laundry care substance has dissolved during the supply period, the obtained highly concentrated washing liquid can be advantageously re-supplied to the laundry during the circulating pumping following the supply period in order to achieve an effective wetting of all areas of the laundry with the highly concentrated washing liquid.

[0029] In an advantageous embodiment, the control device is configured to activate the pump after the laundry tub has rotated at the expulsion speed in order to achieve a circulating pumping of the washing liquid.

[0030] The technical advantage achieved thereby is that it is ensured that the laundry tub does not rotate at the expulsion speed during the circulating pumping, so that the washing liquid pumped in circulation remains in the laundry and is not immediately discharged again.

[0031] In an advantageous embodiment, the control device is configured to activate the tub drive during the supply period so that the laundry tub rotates at a constant expulsion speed or at different expulsion speeds.

[0032] The technical advantage achieved thereby is that, depending on different application situations, both the constant rotation of the laundry tub or the alternating rotation at different expulsion speeds can achieve an advantageous dissolution of the laundry care substance.

[0033] In an advantageous embodiment, the control device is configured to activate the fresh water supply device after the supply period, in particular after the washing liquid has been circulated by the pump, in order to supply at least one further predetermined amount of fresh water to the lye container.

[0034] The technical advantage achieved thereby is that the partial amount of fresh water supplied during the supply period does not ensure a large enough amount of water to completely wet the laundry, and therefore, supplying at least one further predetermined amount of fresh water once or multiple times can ensure complete wetting of the laundry with the washing liquid.

[0035] In an advantageous embodiment, the sum of the predetermined partial amount of fresh water supplied during the supply period and the at least one further predetermined amount of fresh water supplied after the supply period corresponds to the total amount of fresh water supplied during the laundry care program of the laundry care device, where in particular this sum corresponds to the total amount of fresh water required to moisten the laundry received in the laundry tub.

[0036] The technical advantage achieved thereby is that after supplying an additional predetermined amount of fresh water one or more times, it can be ensured that the laundry is completely wetted by the washing liquid.

[0037] In an advantageous embodiment, the control device is configured to activate the tub drive device during the supply of the at least one additional predetermined amount of fresh water, so that the laundry tub rotates at a speed below or above the ejection speed.

[0038] The technical advantage achieved thereby is that in the case where the speed is below the ejection speed, the additional fresh water supplied is not immediately ejected from the laundry again, or in the case where the speed is above the ejection speed, the additional fresh water supplied is immediately ejected from the laundry again.

[0039] According to a second aspect, the object of the present invention is solved by a method for dissolving a laundry care substance in fresh water in a laundry care device, wherein the laundry care device includes: a flushing housing for receiving the laundry care substance; an alkali solution container for receiving the washing liquid, wherein the alkali solution container is fluid-technologically connected to the flushing housing; a fresh water supply device configured to supply fresh water to the flushing housing and convey the laundry care substance received in the flushing housing together with the fresh water to the alkali solution container; a laundry tub for receiving the laundry, wherein the laundry tub is arranged in the alkali solution container; a tub drive device for rotating the laundry tub; and a control device that is control-technologically connected to the fresh water supply device and the tub drive device, and wherein the method includes the following method steps: activating the fresh water supply device by the control device during a supply period to supply a predetermined partial amount of fresh water to the flushing housing and convey the laundry care substance received in the flushing housing together with the predetermined amount of fresh water to the alkali solution container; activating the tub drive device by the control device during the supply period to rotate the laundry tub at a predetermined ejection speed and move the fresh water in the alkali solution container by the rotating laundry tub and dissolve the laundry care substance received in the fresh water to obtain a washing liquid; wherein the predetermined ejection speed corresponds to the following speed: at this speed, the force acting through the rotating laundry tub, in particular the centrifugal force, is large enough to reduce the entry of fresh water into the laundry received in the laundry tub and / or eject the fresh water from the laundry.

[0040] The technical advantage achieved thereby is that the laundry care substance is advantageously dissolved in a predetermined partial amount of fresh water.

[0041] In an advantageous embodiment, a predetermined partial amount of fresh water supplied to the lye container by the fresh water supply device during the supply period is less than the total amount of fresh water required to moisten the laundry received in the laundry tub, wherein the predetermined partial amount of fresh water supplied is selected such that the laundry received in the laundry tub is not completely moistened.

[0042] The technical advantage achieved thereby is that a particularly high concentration of the washing liquid can be achieved.

[0043] In an advantageous embodiment, the laundry care device has a heating element for heating the washing liquid received in the lye container, wherein the control device is connected to the heating element in a control-technical manner, and wherein the method further comprises the step of activating the heating element by the control device during or after the supply period to heat the fresh water or the washing liquid.

[0044] The advantageous embodiment of the laundry care device according to the first aspect is also an advantageous embodiment of the method according to the second aspect, and vice versa. Description of the Drawings

[0045] Embodiments of the present invention are shown in the drawings and are described in detail below.

[0046] In the drawings:

[0048] Figure 2 A schematic view of a laundry care device with a control device is shown; and

[0049] Figure 3 A schematic view of a method for dissolving a laundry care substance in fresh water in a laundry care device is shown. Detailed Description of the Embodiments

[0050] Figure 1 A schematic view of a conventional laundry care device 100 (such as a washing machine) is shown. The laundry care device 100 includes a flushing housing 101 into which a laundry care substance, in particular a detergent or other liquid substance, can be injected. The laundry care device 100 has a device housing 102. The laundry care device 100 includes a device door 103 for loading the laundry care device 100 with laundry.

[0051] Figure 2Schematic diagram showing a laundry care device with a control device. The laundry care device 100 has an alkali solution container 105 for receiving a washing liquid and has a laundry tub 107 for receiving laundry. The laundry tub 107 is arranged in the alkali solution container 105. The laundry care device 100 has a tub drive device 109 for rotating the laundry tub 107.

[0052] An optional circulation pumping system of the laundry care device 100 is described below. This circulation pumping system exists in Figure 2 the embodiments, but it is not necessary to have this circulation pumping system to implement the present invention. Here, the alkali solution container 105 has a discharge port 111. Here, the laundry care device 100 has a supply element 113. The discharge port 111 is fluid-technologically connected to the supply element 113 through a liquid pipeline 115, and a pump 117 for pumping the washing liquid through the liquid pipeline 115 is arranged in the liquid pipeline 115. During Figure 2 the unshown circulation pumping process, the pump 117 can pump the washing liquid from the alkali solution container 105 through the discharge port 111 into the liquid pipeline 115 and can re-supply the washing liquid to the alkali solution container 105 and the laundry tub 107 through the liquid pipeline 115 and the supply element 113. Therefore, during the laundry care process, the washing liquid can be effectively circulated and pumped through the liquid pipeline 115 and re-supplied to the laundry in the laundry tub 107. Thus, an effective optional circulation pumping system is implemented in the laundry care device 100.

[0053] In addition, the laundry care device 100 further includes a flushing housing 101 only schematically shown in Figure 2 , into which the user of the laundry care device 100 injects a laundry care substance, and the laundry care device 100 further includes a fresh water supply device 118-1 only schematically shown in Figure 2 , which is fluid-technologically connected to the laundry care device 100 at Figure 2 a fresh water interface not shown. The flushing housing 101 is fluid-technologically connected to the alkali solution container 105 through a supply pipeline 118-2. The fresh water supply device 118-1 is fluid-technologically connected to the flushing housing 101 through a fresh water pipe 118-3. Therefore, the fresh water supply device 118-1 can be configured to flush the laundry care substance received in the flushing housing 101 into the alkali solution container 105 through the supplied fresh water.

[0054] In addition, the laundry care device 100 further has a heating element 123 arranged in the alkali solution container 105, particularly in the lower region of the alkali solution container 105, and the heating element is configured to heat the fresh water or the washing liquid received in the alkali solution container 105.

[0055] In addition, the laundry care device 100 further includes a control device 119, which is respectively connected to the pump 117, the tub drive device 109, the fresh water supply device 118-1, and the heating element 123 through control connections 121.

[0056] In addition, the laundry care device 100 further includes a discharge line 125, which is fluid-technologically connected to the liquid line 115. The pump 117 is configured to pump the washing liquid out of the lye container 105 through the discharge port 111 during a pumping-out process (not shown in the figure), and pump it out of the laundry care device 100 through the liquid line 115 and the discharge line 125. It is also possible that there are two pumps 117, one of which is used to pump the washing liquid out of the discharge line 125, and the other is used to circulate and pump the washing liquid in the liquid line 115. Figure 2

[0057] In addition, the laundry care device 100 particularly further includes Figure 2 a level sensor (not shown in the figure) for detecting the level of the washing liquid in the lye container 105.

[0058] To ensure the favorable dissolution of the laundry care substance in the supplied fresh water, the control device 119 is configured to activate the fresh water supply device 118-1 during a supply time period to supply a predetermined partial amount of fresh water into the flushing housing 101, and convey the laundry care substance received in the flushing housing 101 together with the predetermined partial amount of fresh water into the lye container 105.

[0059] Here, the predetermined partial amount of fresh water supplied to the lye container 105 by the fresh water supply device 118-1 during the supply time period only corresponds to a part of the total amount of fresh water supplied during the laundry care program of the laundry care device 100. In particular, the predetermined partial amount of fresh water is less than the total amount of fresh water required to completely wet the laundry received in the laundry tub 107.

[0060] According to this embodiment, the control device 119 is configured to activate the tub drive device 109 during the supply time period to rotate the laundry tub 107 at a predetermined driving speed, and cause the fresh water in the lye container 105 to move through the rotating laundry tub 107, and dissolve the laundry care substance received in the fresh water to obtain the washing liquid.

[0061] By rotating the laundry tub 107 at a predetermined driving speed, the fresh water supplied to the lye container 105 moves mechanically in such a way that the undissolved part of the laundry care substance is favorably dissolved in the moving fresh water, thereby obtaining the washing liquid.

[0062] ​Due to the relatively small predetermined partial amount of fresh water used, the laundry care substance concentration of the washing liquor obtained during the supply period is significantly higher than, for example, the concentration achievable in a conventional laundry care process.

[0063] By subsequently adding the correspondingly highly concentrated, especially heated, washing liquor to the laundry, it is particularly beneficial for the laundry core because the mechanical forces acting in the laundry core are lower and the flow rate is lower, thus improving the laundry care effect.

[0064] Furthermore, no additional water circuit is required in the laundry care device 100 to dissolve the laundry care substance, but the highly concentrated, especially heated, washing liquor is conveyed by the barrel movement and / or convection (i.e., the movement of the washing liquor).

[0065] Since the predetermined partial fresh water supply quantity is less than the quantity required to completely moisten the laundry, it must be ensured that the supplied fresh water either does not come into contact with the laundry at all or only comes into contact with the laundry to a very small extent or the corresponding fresh water bound to the laundry is expelled from the laundry again.

[0066] Therefore, during the supply period, the laundry barrel 107 rotates at a predetermined expulsion rotational speed by means of the control device 119. The predetermined expulsion rotational speed corresponds to the rotational speed at which the force acting on the fresh water by the movement of the barrel and / or the centrifugal force acting by the rotating laundry barrel 107 is large enough to reduce the entry of fresh water into the laundry received in the laundry barrel 107 and / or to expel the fresh water from the laundry.

[0067] This ensures that there is enough free fresh water, i.e., fresh water not bound to the laundry, in the lye container 105 to completely dissolve the laundry care substance in the fresh water.

[0068] In particular, the expulsion rotational speed is here from 30 to 500 revolutions per minute, especially from 40 to 150 revolutions per minute.

[0069] The control device 119 is here especially configured to activate the barrel drive device 109 during the supply period so that the laundry barrel 107 rotates at a constant expulsion rotational speed or at different expulsion rotational speeds.

[0070] To further improve the dissolution of the laundry care substance in the moving fresh water, the control device 119 is especially configured to activate the heating element 123 during or after the supply period to heat the fresh water or the washing liquor. By heating the fresh water during the supply period or by heating the washing liquor after the supply period, an improved dissolution of the laundry care substance can be ensured.

[0071] In particular, the laundry care device 100 has a liquid level sensor for detecting the level of the washing liquid in the lye container 105, wherein the control device 119 is configured here to activate the heating element 123 when the detected washing liquid level exceeds a minimum level threshold. Here, the minimum level threshold corresponds to the following level of the washing liquid: this level is just above the heating element 123 in the lye container 105 to prevent dry running of the heating element 123.

[0072] Furthermore, the control device 119 is in particular configured to activate the tub drive device 109 when the heating element 123 is activated, so that the laundry tub 107 rotates at a speed below the maximum tub speed to ensure that the heating element 123 is covered by the washing liquid. Here, the maximum tub speed corresponds to the following speed of the laundry tub 107: at this speed, the fresh water moved by the laundry tub 107 can still partially cover the heating element 123, thereby preventing dry running of the heating element 123.

[0073] After the laundry care substance has dissolved, the control device 119 in particular activates the pump 117, pumps the washing liquid out of the discharge port 111 and re-supplies the pumped washing liquid to the lye container 105 via the supply element 113 to pump the washing liquid in a cycle. Thereby, it is possible to wet the laundry completely and effectively with a correspondingly highly concentrated, in particular heated, washing liquid, thus ensuring the above advantages.

[0074] The control device 119 is in particular configured here to activate the pump 117 after the laundry tub 107 has rotated at the ejection speed to pump the washing liquid in a cycle.

[0075] After pumping the washing liquid in a cycle by the pump 117, the control device 119 in particular activates the fresh water supply device 118-1 to supply at least one further predetermined amount of fresh water to the lye container 105. This can include a single supply of a further predetermined amount of fresh water or multiple supplies of a further predetermined amount of fresh water.

[0076] The at least one further predetermined amount of fresh water supplied and the predetermined partial amount of fresh water already supplied during the supply period are sufficient to make the volume of the washing liquid large enough to achieve complete wetting of the laundry received in the laundry tub 107.

[0077] The control device 119 is in particular configured here to activate the tub drive device 109 during the supply of at least one further predetermined amount of fresh water so that the laundry tub 107 rotates at a speed below the ejection speed, so that the washing liquid remains in the laundry.

[0078] In this way, a favorable laundry care process is achieved.

[0079] Figure 3 Schematic diagram showing a method for dissolving a laundry care substance in fresh water in a laundry care device.

[0080] As a first method step, the method 200 includes activating, during a supply time period, the fresh water supply device 118 - 1201 by the control device 119 to supply a predetermined partial amount of fresh water into the flushing housing 101 and to convey the fabric care substance received in the flushing housing 101 together with the predetermined partial amount of fresh water into the lye container 105.

[0081] As a second method step, the method 200 includes activating, during a supply time period, the tub drive device 109 by the control device 119 to rotate the laundry tub 107 at a predetermined ejection rotational speed and to move the fresh water in the lye container 105 by the rotating laundry tub 107 and to dissolve the fabric care substance received in the fresh water, thereby obtaining a washing liquid, wherein the predetermined ejection rotational speed corresponds to a rotational speed at which the force acting on the fresh water by the tub movement and / or the centrifugal force acting by the rotating laundry tub 107 is large enough to reduce the entry of fresh water into the laundry received in the laundry tub 107 and / or to eject the fresh water from the laundry.

[0082] All features described and shown in connection with the various embodiments of the present invention can be arranged in different combinations in the subject matter of the present invention in order to achieve their advantageous effects simultaneously.
