Description

Technical Field

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

[0002] In conventional clothing care devices, different methods are used to care for clothing received in a clothing tub. Here, the clothing tub is rotated in a lye container containing washing liquid, in particular at different rotation speeds, so as to advantageously move the clothing received in the clothing tub and the washing liquid received in the lye container. This allows sufficient contact between the clothing and the washing liquid to ensure that clothing care substances or heat can be effectively transferred from the washing liquid to the clothing.

[0003] To ensure effective laundry care for the laundry received in the laundry tub, all areas of the laundry must reach the temperature required by the laundry care substance. Due to the unpredictable movement behavior of the laundry in the rotating laundry tub, in conventional laundry care devices, it may happen that some laundry items, in particular laundry items such as in the core of the laundry received in the laundry tub, are not in sufficient contact with the washing liquid and are therefore not heated to the required temperature, which may affect the laundry care quality or lead to increased energy consumption due to additional heating.

[0004] Document DE 10 2019 216 697 A1 discloses a clothing care appliance having a loading recognition device. Summary of the invention

[0005] The object underlying the present invention is to provide a laundry care appliance with which an advantageous laundry care process can be ensured.

[0006] The object is achieved by the preferred technical solution of the present invention. Advantageous embodiments are the subject of the optional technical solution, the description and the drawings.

[0007] According to a first aspect, the object of the present invention is solved by a clothing care device, which comprises: a lye container for receiving washing liquid; a clothes barrel for receiving clothes, wherein the clothes barrel is arranged in the lye container; a barrel drive device for rotating the clothes barrel; a heating element for heating the washing liquid in the lye container; a washing liquid supply device, which is fluidically connected to the lye container via a supply pipeline and is configured to supply washing liquid to the lye container; and a control device, which is control-technically connected to the barrel drive device, the heating element and the washing liquid supply device, wherein the control device is configured to activate the washing liquid supply device during a first filling time period to supply a first filling amount of washing liquid to the lye container, wherein, after the first filling amount is supplied, the first filling level of the washing liquid in the lye container is at least high enough to make the inner side of the clothes barrel contact with the washing liquid to achieve soaking the clothes received in the clothes barrel with the washing liquid, wherein the control device is configured to activate the washing liquid supply device during the first filling time period to supply a first filling amount of washing liquid to the lye container. The control device is configured to activate the tub drive device during the heating time period to rotate the laundry tub, wherein the control device is configured to activate the tub drive device during the first rotation time period after the heating time period to rotate the laundry tub at different rotation speeds so as to achieve heating of the laundry in the laundry tub by contact with the laundry liquid, wherein the control device is configured to activate the laundry liquid supply device during a second filling time period after the rotation time period to supply a second filling amount of laundry liquid to the alkali liquid container, wherein after the second filling time period, the second filling level of the laundry liquid in the alkali liquid container is at least high enough to fill the lower area of ​​the laundry tub with the laundry liquid, wherein the control device is configured to activate the tub drive device during the second rotation time period after the second filling time period to rotate the laundry tub at different rotation speeds so as to achieve heating of the laundry in the laundry tub by contact with the laundry liquid.

[0008] The technical advantage achieved thereby is that, by using different continuous time periods according to the first aspect, the duration of the corresponding clothing care program can be advantageously shortened, the clothing care efficiency of the clothing care program can be advantageously improved, and the energy consumption of the clothing care equipment during the clothing care program can also be advantageously reduced.

[0009] A laundry care device is understood to be a device for caring for laundry, such as a washing machine or a laundry dryer. In particular, such a laundry care device is understood to be a household laundry care device. In other words, such a laundry care device is used within the framework of household management and processes laundry in normal household quantities.

[0010] The supply of washing liquid can be monitored by various means using sensors provided for this purpose, which are connected to the control device. For example, the clothing care device may include a flow sensor that detects the filling amount supplied by the washing liquid supply device. Alternatively or additionally, the clothing care device may also be equipped with a level sensor or a pressure sensor connected to the control device that detects the filling level of the washing liquid in the alkali liquid container. For example, when the level sensor or the pressure sensor detects a predetermined filling level (such as the first or second filling level), the activated washing liquid supply device for supplying washing liquid will be deactivated. Therefore, after a certain amount of washing liquid is added, the filling level in the alkali liquid container is at least as high as the predetermined filling level (such as the first or second filling level). This is particularly applicable to the time period immediately following the deactivation of the supply device. In the time period after the filling time period, the filling level in the alkali liquid container may drop again because the clothes have absorbed the washing liquid.

[0011] In a preferred embodiment, the control device is configured to activate the barrel drive device during a first filling time period to rotate the clothing barrel at a first rotational speed, in particular to reverse in the opposite direction of rotation, wherein the first rotational speed is lower than the abutment speed of the clothing barrel, at which the clothing abuts against the clothing barrel due to the action of centrifugal force.

[0012] The technical advantage achieved thereby is that the washing liquid of the first filling amount supplied during the first filling time period can be effectively distributed, thereby advantageously soaking the clothes with washing liquid. In addition, due to the low first rotation speed, it can also be ensured during the first filling time period that the clothes will not be damaged when fully loaded or incorrectly loaded.

[0013] In particular, the first rotation speed is 35 revolutions per minute.

[0014] In an advantageous embodiment, a plurality of protrusions are arranged on the inner side of the laundry tub for moving the laundry in the laundry tub, wherein, after supplying a first filling amount in a first filling time period, a first filling level of washing liquid in the alkali liquid container is at least high enough that one of the plurality of protrusions is located at a rotation position of the laundry tub at the 6 o'clock position of the laundry tub, and the maximum height of the protrusion covered by the washing liquid is 30% of its total height, and / or after supplying a second filling amount in a second filling time period, a second filling height of washing liquid in the alkali liquid container is at least high enough that one of the plurality of protrusions is located at a rotation position of the laundry tub at the 6 o'clock position of the laundry tub, and the protrusion is completely covered by the washing liquid.

[0015] The technical advantage achieved thereby is that, since the first filling amount of washing liquid introduced into the alkali liquid container in the first filling time period is lower than the second filling amount, although the clothes can be just soaked with washing liquid, the first filling amount is so low that a high concentration of clothing care substances in the first filling amount is ensured, while also achieving relatively fast heating of the lower first filling amount with lower heating energy.

[0016] By supplying the second filling amount later during the second filling period, it can be ensured that the laundry is subsequently completely wetted with the previously heated washing liquid.

[0017] In particular, the 6 o'clock position of the laundry tub means that one of the plurality of protrusions is located at the lowest position inside the laundry tub, so that when the filling level of the washing liquid in the lye container rises, the washing liquid first contacts this corresponding protrusion.

[0018] In an advantageous embodiment, the control device is configured to end the heating period and deactivate the heating element when a predetermined heating period has elapsed or when a temperature value detected by a temperature sensor of the laundry care appliance reaches a predetermined temperature limit value.

[0019] The technical advantage achieved thereby is that the first fill quantity of washer fluid is effectively heated to a desired temperature value during the heating period.

[0020] In a preferred embodiment, the control device is configured to activate the barrel drive device during the heating time period to rotate the clothing barrel at a second speed curve and a third speed curve, in particular to reverse the clothing barrel in the opposite rotation direction, wherein the rotation speed of the second speed curve and the rotation speed of the third speed curve are lower than the abutment speed of the clothing barrel, at which the clothing rests on the clothing barrel due to the action of centrifugal force, wherein the rotation speed of the second speed curve is lower than the rotation speed of the third speed curve, wherein the second and third speed curves each include multiple variable speeds.

[0021] The technical advantage achieved thereby is that a favorable effect is achieved by changing the rotation speed of the laundry tub during the heating period. The rotation of the laundry tub at the second, lower rotation speed ensures effective distribution of the washing liquid in the laundry tub during the heating period. The rotation of the laundry tub at the third, higher rotation speed ensures effective dissolution of the laundry care substance in the washing liquid in the laundry tub during the heating period and also enables effective exchange of washing liquid with the laundry in the lower area of ​​the laundry tub.

[0022] In one advantageous specific embodiment, the ratio of the second rotational speed curve to the third rotational speed curve during the heating period is approximately 1:1.

[0023] The technical advantage achieved thereby is that the temperature rise in the core area of ​​the garment is particularly uniform.

[0024] In a preferred embodiment, the control device is configured to activate the tub drive device during the heating time period to rotate the clothes tub multiple times at a second speed curve, and in particular to reverse the clothes tub in the opposite direction during the multiple rotations, and the control device is configured to subsequently activate the tub drive device to rotate the clothes tub multiple times at a third speed curve, and in particular to reverse the clothes tub in the opposite rotation direction during the multiple rotations.

[0025] The technical advantage achieved thereby is that effective and complete wetting of the laundry with the heated washing liquid is ensured.

[0026] In an advantageous embodiment, the control device is configured to activate the tub drive during the first and / or second rotation time period to rotate the laundry tub in a first rotation direction at a fourth rotation speed profile and reverse in a second rotation direction opposite to the first rotation direction at a fifth rotation speed profile.

[0027] The technical advantage achieved thereby is that the fourth and the fifth rotational speed profile ensures particularly advantageous care of the laundry during the first and / or second rotation time period.

[0028] In a preferred embodiment, the fourth speed curve includes the clothes barrel rotating at a first speed range, the next clothes barrel rotating at a second speed range, and the next clothes barrel rotating at a third speed range, wherein the first speed range is lower than the abutting speed of the clothes barrel, at which the clothes stick to the clothes barrel due to the action of centrifugal force, wherein the second speed range includes the abutting speed, and wherein the third speed range is greater than the abutting speed and includes a driving-out speed, at which the washing liquid combined with the clothes is driven out of the clothes due to the centrifugal force acting on the clothes.

[0029] The technical advantage achieved thereby is that the rotation of the laundry tub in the first and second speed ranges ensures efficient distribution of the laundry (particularly the laundry core) and efficient distribution of the heated washing liquid. By rotating the laundry tub in the third higher speed range, at least a portion of the washing liquid bound to the laundry is thrown out and can be reabsorbed by the laundry during subsequent rotation at a lower speed.

[0030] In a preferred embodiment, the fifth speed curve includes the laundry tub rotating in a first speed range, the next laundry tub rotating in a second speed range, and the next laundry tub rotating in the first speed range, wherein the first speed range is lower than the abutting speed of the laundry tub, and wherein the second speed range includes the abutting speed.

[0031] The technical advantage achieved thereby is that the rotation of the laundry tub in the first and second speed ranges ensures efficient distribution of the laundry (particularly the laundry core) and efficient distribution of the heated washing liquid. Since the fourth speed curve already includes the rotation at the high speed of the third speed range, the fifth speed curve no longer requires a corresponding rotation.

[0032] In an advantageous embodiment, the control device is configured to rotate the laundry tub at a fifth speed after the laundry tub rotates at a fourth speed, particularly with a pause between the fourth speed and the fifth speed, thereby changing the rotation direction of the laundry tub.

[0033] The technical advantage achieved thereby is that effective laundry care is ensured.

[0034] In an advantageous embodiment, the ratio of the rotation of the laundry tub at the fifth speed curve to the rotation of the laundry tub at the fourth speed curve is approximately 1:1, or the ratio of the rotation of the laundry tub at the fifth speed curve to the rotation of the laundry tub at the fourth speed curve is between 2:1 and 10:1.

[0035] The technical advantage achieved thereby is that the laundry care process can be effectively adjusted.

[0036] In particular, the control device is designed to vary the ratio between the fifth rotational speed curve and the fourth rotational speed curve as a function of the amount of washing liquid supplied to the lye container within the scope of the first and / or second filling period.

[0037] In a preferred embodiment, the control device is configured to activate the washing liquid supply device to supply a second filling amount of washing liquid to the alkali liquid container during a mixing time period after the second rotation time period, activate a pump of the clothing care device that is fluidically connected to the washing liquid container to pump washing liquid out of the alkali liquid container, and activate the tub drive device to rotate the clothing tub in a first rotation direction at a fourth speed curve and reverse in a second rotation direction opposite to the first rotation direction at a fifth speed curve.

[0038] The technical advantage achieved thereby is that a particularly efficient rinsing process can be achieved.

[0039] In a preferred embodiment, the control device is configured to activate the drum drive device to rotate the clothing drum at a drying speed during a second rotation time period, in particular a drying time period after the mixing time period, so that the washing liquid combined with the clothes is driven out again due to the centrifugal force acting on the clothes, thereby drying the clothes.

[0040] The technical advantage achieved thereby is that the laundry is dried particularly effectively at the end of the laundry care process.

[0041] According to a second aspect, the task is performed by a method for caring for laundry in a laundry care device, wherein the laundry care device comprises: an alkaline solution container for receiving a washing liquid; a laundry drum for receiving laundry, wherein the laundry drum is arranged in the alkaline solution container; a drum drive device for rotating the laundry drum; a heating element for heating the washing liquid in the alkaline solution container; a washing liquid supply device which is fluid-technically connected to the alkaline solution container via a supply line and is configured to supply the washing liquid to the alkaline solution container; and a control device which is control-technically connected to the drum drive device, the heating element and the washing liquid supply device, wherein the method comprises the following method steps: activating, by means of the control device, the washing liquid supply device during a first filling period to supply a first filling quantity of the washing liquid to the alkaline solution container, wherein, after supplying the first filling quantity, the first filling level of the washing liquid in the alkaline solution container is at least high enough for the inner side of the laundry drum to be in contact with the washing liquid in order to wet the laundry received in the laundry drum with the washing liquid; activating, by means of the control device, the heating element during a heating period following the first filling period to heat the washing liquid, wherein the control device is configured to activate the drum drive device during the heating period to rotate the laundry drum; activating, by means of the control device, the drum drive device during a first rotation period following the heating period to rotate the laundry drum at different rotational speeds in order to heat the laundry in the laundry drum by contact with the washing liquid; activating, by means of the control device, the washing liquid supply device during a second filling period following the first rotation period to supply a second filling quantity of the washing liquid to the alkaline solution container, wherein, after the second filling period, the second filling level of the washing liquid in the alkaline solution container is at least high enough for the lower region of the laundry drum to be filled with the washing liquid; and activating, by means of the control device, the drum drive device during a second rotation period following the second filling period to rotate the laundry drum at different rotational speeds in order to heat the laundry in the laundry drum by contact with the washing liquid.

[0042] The technical advantage achieved thereby is to ensure an effective laundry care process.

[0043] An 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

[0056] Figure 1 Schematic diagram showing a common laundry care device 100 (such as a washing machine). The laundry care device 100 includes a flushing shell 101 into which laundry care substances, such as detergents or other liquid substances, can be filled. The laundry care device 100 has a device shell 102. The laundry care device 100 includes a device door 103 for loading laundry into the laundry care device 100.

[0057] Figure 2A schematic diagram of a clothing care device with a control device is shown. The clothing care device 100 has a lye container 105 for receiving washing liquid and a clothes tub 107 for receiving clothes. The clothes tub 107 is arranged in the lye container 105. The clothing care device 100 has a tub drive 109 for rotating the clothes tub 107. The lye container 105 has a discharge port 111. The discharge port 111 is fluidically connected to a pump 117 via a fluid line 115. Figure 2 During a pumping process (not shown), the pump 117 can pump the washing liquid from the alkaline solution container 105 into the liquid line 115 through the discharge opening 111 and then out of the laundry care device 100 through the outlet line 125 .

[0058] The clothing care device 100 includes a washing liquid supply device 118 - 1 for supplying washing liquid to the alkali liquid container 105 , wherein the washing liquid supply device 118 - 1 is connected to the alkali liquid container 105 via a supply pipe 118 - 2 .

[0059] In particular, the detergent supply device 118-1 includes the laundry care device 100. Figure 2 The flushing housing 101 and / or the clothing care device 100 not shown in FIG. Figure 2 A fresh water interface (not shown) is provided in the figure, wherein the control device 119 of the laundry care device 100 is configured to activate the washing liquid input via the flushing shell 101 and / or the fresh water interface so as to supply washing liquid and / or fresh water as washing liquid into the laundry tub 107.

[0060] The laundry care appliance 100 has a heating element 120 which is arranged in the laundry liquid container 105 and is designed to heat the washing liquid in the laundry liquid container 105 , wherein the heating element 120 is connected to the control device 119 via control technology.

[0061] The clothing care device 100 further comprises a temperature sensor 123 for detecting the temperature of the washing liquid in the alkali liquid container 105. In particular, the temperature sensor 123 is arranged in the alkali liquid container 105.

[0062] The clothing care device 100 further comprises a control device 119 which is connected to the pump 117, the tub drive device 109, the detergent supply device 118-1, the heating element 120 and the temperature sensor 123 via control connections 121, respectively.

[0063] in particular, Figure 2 The garment care appliance 100 is shown without a circulation pumping function.

[0064] Figure 3A schematic diagram of a laundry liquid container of a laundry care appliance is shown with a first fill quantity of washing liquid.

[0065] Figure 3 The illustrated lye container 105 has a laundry tub 107 in which a projection 127 is arranged, which is designed to move laundry items received in the laundry tub 107 when the laundry tub 107 is rotated. Figure 3 The 6 o'clock position of the laundry tub 107 is shown, in which position one of the projections 127 is arranged in the lowermost region of the laundry tub 107 .

[0066] from Figure 3 It can be seen in FIG. 1 that after supplying the first filling amount of washing liquid 129 , the alkaline solution container 105 has a first filling level 131 , which is at least high enough to make the inner side 133 of the laundry tub 107 contact the washing liquid 129 .

[0067] In particular, the first filling level 131 of the washing liquid 129 is high enough that the bulge 127 at the 6 o'clock position of the laundry tub 107 is covered by the washing liquid 129 up to 30% of its total height 135 .

[0068] Therefore, although the first filling level 131 of the washing liquid 129 is just enough to soak the clothes in the laundry tub 107 with the washing liquid 129, the first filling level is low enough to achieve rapid heating of the washing liquid 129 and a high concentration of clothing care substances in the washing liquid 129.

[0069] Figure 4 A schematic diagram showing a clothing care process according to one embodiment.

[0070] exist Figure 4 , only such a time period of the clothing care process is shown, which time period includes the first filling time period 137 , the heating time period 139 after the first filling time period 137 , and the first rotation time period 141 after the heating time period 139 .

[0071] Figure 4 A first curve 143 is shown, along an axis of ordinate 145 , showing the rotational speed of the laundry tub 107 driven by the tub drive 109 as a function of time, the rotational speed being plotted along an axis of abscissa 147 .

[0072] Figure 4 The second curve 149 shown in FIG. 1 shows the filling level of the washing liquid 129 in the lye container 105 as a function of time along the ordinate axis 145 .

[0073] Figure 4The third curve 151 shown in FIG. 1 shows along the ordinate axis 145 the temperature of the washing liquid 129 in the lye container 105 as a function of time, the temperature being detected by a temperature sensor 123 arranged in the lye container 105 .

[0074] Figure 4 The other curve shown in and with reference numeral 152 shows along the ordinate axis 145 a plurality of temperatures in different areas of the laundry in the laundry tub 107 as a function of time, the temperatures being detected by a laundry temperature sensor arranged in the laundry tub.

[0075] Figure 4 The time period of the laundry care process according to this embodiment shown starts from a first filling time period 137, during which the control device 119 of the laundry care device 100 activates the washing liquid supply device 118-1 for supplying a first filling amount of washing liquid 129 to the alkali liquid container 105. After the first filling amount is supplied, the first filling level 131 of the washing liquid 129 in the alkali liquid container 105 is at least high enough to make the inner side 133 of the laundry tub 107 contact the washing liquid 129, so as to achieve soaking the laundry received in the laundry tub 107 with the washing liquid 129. For further details on the first filling level 131, please refer to Figure 3 Description.

[0076] from Figure 4 It can also be seen that the control device 119 is configured to activate the tub drive device 109 during the first filling time period 137 to rotate the laundry tub 107 at a first rotation speed 153, in particular in the opposite rotation direction. The first rotation speed 153 is lower than the rotation speed of the laundry tub 107. Figure 4 106. The first rotation speed 153 is not shown in the figure, at which the clothes are pressed against the clothes barrel 107 due to the effect of the centrifugal force. In particular, the first rotation speed 153 is about 35 revolutions per minute.

[0077] Although the lower first rotation speed 153 can achieve wetting of the clothes, it can also prevent the clothes from being damaged, especially when the clothes tub 107 is fully loaded or incorrectly loaded.

[0078] The first filling period 137 is followed by a heating period 139, during which the control device 119 activates the heating element 120 to heat the washing liquid 129, so that Figure 4 As shown, the temperature of the washing liquid 129 and the temperature of the clothes will increase.

[0079] Here, the control device 119 is particularly designed to end the heating time period 139 and deactivate the heating element 120 when a predetermined heating period has elapsed or the temperature value detected by the temperature sensor 123 of the laundry care device 100 reaches a predetermined temperature limit value.

[0080] from Figure 4 As can be seen in FIG. 1 , the control device 119 is configured to activate the tub drive device 109 during the heating period 139 to rotate the laundry tub 107. For the specific rotation of the laundry tub 107 during the heating period 139, please refer to the following description of the rotation of the laundry tub 107 during the heating period 139. Figure 5 Description.

[0081] The heating time period 139 is followed by a first rotation time period 141, during which the control device 119 is configured to activate the tub drive device 109 to rotate the laundry tub 107 at different rotation speeds so as to heat the laundry in the laundry tub 107 by contact with the washing liquid 129. For the specific rotation of the laundry tub 107 during the first rotation time period 141, please refer to the following description of the first rotation time period 141. Figure 6 Description.

[0082] Figure 5 Shown in Figure 4 A schematic diagram of a rotation speed curve of a tub drive device during a heating period of a clothing care process is shown.

[0083] from Figure 5 It can be seen that the control device 119 is configured to activate the tub drive 109 during the heating time period 139 so that the laundry tub 107 rotates at the second rotation speed curve 155 and the third rotation speed curve 157 .

[0084] Here, the speed of the second speed curve 155 is lower than the speed of the third speed curve 157. Here, the speed of the second speed curve 155 and the speed of the third speed curve 157 are both lower than the speed of the laundry tub 107. Figure 5 The abutment speed not shown in the figure, at which the clothes abut against the clothes barrel 107 due to the centrifugal force.

[0085] from Figure 5 It can also be seen that both the second rotational speed curve 155 and the third rotational speed curve 157 include a plurality of variable rotational speeds.

[0086] In particular, the variable speed of the second speed curve 155 includes a speed of 35 to 45 revolutions per minute, so that when the laundry tub 107 rotates accordingly, the laundry received in the laundry tub 107 will fall from the inner side 133 of the laundry tub 107 ("falling mode").

[0087] In particular, the variable speed of the third speed curve 157 includes a speed of 45 to 65 revolutions per minute, so that when the laundry tub 107 rotates accordingly, the clothing care substances can be effectively dissolved and the laundry can be effectively soaked with the detergent 129 ("soaking mode").

[0088] from Figure 4It can also be seen that during the heating time period 139, the laundry tub 107 is rotated alternately once in the opposite rotation direction by the tub drive 109 both during the second speed curve 155 and during the third speed curve 157. Figure 5 In the figure, only the absolute value of the rotational speed is shown on the vertical axis, so the second blocks of the second speed curve 155 or the third speed curve 157 also show positive values, even though the rotation direction of the laundry tub 107 in these second blocks is opposite to the rotation direction of the laundry tub in the first blocks of the second speed curve 155 or the third speed curve 157.

[0089] In addition, from Figure 5 It can be seen that during the heating period 139 , the ratio of the second rotational speed curve 155 to the third rotational speed curve 157 is approximately 1:1.

[0090] therefore, Figure 5 The control device 119 shown can reverse the barrel drive device 109 in the opposite direction during the heating time period 139 to rotate the clothing barrel 107 several times, especially twice, at the second speed curve 155, and then reverse the barrel drive device 109 in the opposite rotational direction to rotate the clothing barrel 107 several times, especially twice, at the third speed curve 157.

[0091] Figure 6 Shown in Figure 4 Schematic diagram of the rotation speed curve of the tub drive device during the first rotation time period 141 of the clothing care process is shown.

[0092] from Figure 6 It can be seen that the control device 119 is configured to activate the tub drive 109 during the first rotation time period 141 so that the laundry tub 107 rotates at the fourth rotation speed curve 159 and the fifth rotation speed curve 161 .

[0093] In the framework of the fourth speed curve 159, the tub drive 109 rotates the laundry tub 107 in a first rotational direction, and in the framework of the fifth speed curve 161, the tub drive 109 rotates the laundry tub 107 in a second rotational direction opposite to the first rotational direction. Figure 4 As shown in FIG. 1 for the first rotation time period 141. Figure 6 For ease of explanation, only the value of the rotation speed is shown.

[0094] from Figure 6 It can be seen that the fourth speed curve 159 includes the laundry tub 107 rotating in the first speed range 163 , the next laundry tub 107 rotating in the second speed range 165 , and the next laundry tub 107 rotating in the third speed range 167 .

[0095] The speed of the first speed range 163 is lower than Figure 6 The rotation speed of the laundry drum 107 is not shown, at which the laundry is pressed against the laundry drum 107 due to the centrifugal force. The rotation speed of the second rotation speed range 165 includes the corresponding pressing rotation speed.

[0096] The first rotation speed range 163 is particularly between 35 and 45 revolutions per minute, so that when the laundry tub 107 rotates accordingly, the laundry received in the laundry tub 107 falls from the inner side 133 of the laundry tub 107 and thus moves the laundry core ("falling mode").

[0097] The rotation speed of the second rotation speed range 165 particularly includes a rotation speed of 45 to 65 revolutions per minute, so that when the laundry drum 107 rotates accordingly, the clothing care substance can be effectively dissolved and the clothes can be effectively soaked by the detergent 129 ("soaking mode").

[0098] The 3rd rotating speed range 167 is larger than the rotation speed of abutting and comprises the driving out rotation speed, and at this driving out rotation speed, the washing liquid 129 that is combined on the clothes is driven out from the clothes by the centrifugal force that acts on the clothes. Particularly, the 3rd rotating speed 167 is up to 120 revolutions per minute.

[0099] from Figure 6 It can be seen that after the laundry tub 107 rotates in the third speed range 167 , the fourth speed curve 159 includes the laundry tub 107 rotating again in the speed of the second speed range 165 .

[0100] from Figure 6 It can be seen that after the fourth speed curve 159, after a short pause and changing the rotation direction of the laundry tub 107, the fifth speed curve 161 follows.

[0101] The fifth speed curve 161 includes the laundry tub 107 rotating in the first speed range 163, the next laundry tub 107 rotating in the second speed range 165, and the next laundry tub 107 rotating in the third speed range 167. Here, the first speed range 163 is lower than the contact speed of the laundry tub 107 and the second speed range 165 includes the contact speed.

[0102] For example, if the abutment rotation speed of the clothes barrel 107 is 60 revolutions per minute, the second rotation speed range 165 may include a range of 45 to 70 revolutions per minute (in the case of full load, such as when the barrel volume per kilogram of load is less than a specific load volume of 9 liters), or, the second rotation speed range 165 may include a range of 45 to 65 revolutions per minute (in the case of partial load, such as when the barrel volume per kilogram of load is less than a specific load volume of 9 liters), or, the second rotation speed range 165 may include a range of 45 to 60 revolutions per minute (in the case of small load, such as when the barrel volume per kilogram of load is greater than a specific load volume of 20 liters). The specific load volume is an indicator of the load volume of clothes put into the clothes barrel. The barrel volume in liters is divided by the load volume in kilograms, which is why the specific load volume decreases as the load volume increases.

[0103] Unlike the fourth rotation speed curve 159 , the fifth rotation speed curve 161 does not include the laundry tub 107 rotating in the third rotation speed range 167 .

[0104] from Figure 6 It can be seen from the figure that the ratio of the rotation of the laundry tub 107 according to the fifth rotation speed curve 161 to the rotation of the laundry tub 107 according to the fourth rotation speed curve 159 is approximately 1:1.

[0105] Figure 7 A schematic diagram of a laundry liquid container of a laundry care appliance is shown with a second fill quantity of washing liquid.

[0106] In a second filling period 169 after the first rotation period 141 , a second filling amount of cleaning liquid 129 is supplied to the alkaline liquid container 105 .

[0107] Figure 7 and Figure 3 Similarly, the 6 o'clock position of the laundry tub 107 is shown, in which position one of the protrusions 127 is arranged in the lowermost area of ​​the laundry tub 107 .

[0108] from Figure 3 It can be seen in FIG. 1 that after supplying the second filling amount of washing liquid 129 , the alkaline solution container 105 has a second filling level 171 which is at least high enough that a lower area 173 of the laundry tub 107 is covered by the washing liquid 129 .

[0109] In particular, the second filling level 171 of the washing liquid 129 is high to such an extent that the protrusion 127 at the 6 o'clock position of the laundry tub 107 is almost completely covered by the washing liquid 129 .

[0110] Figure 8 Show Figure 4A schematic diagram of a second filling period 169 after a laundry care process and a second rotation period 175 thereafter is shown.

[0111] about Figure 8 For annotations to the diagrams in Figure 4 Detailed description.

[0112] from Figure 8 It can be seen that the first rotation period 141 is followed by a second filling period 169 , and the second filling period 169 is followed by a second rotation period 175 .

[0113] The control device 119 is designed to activate the washing liquid supply device 118-1 during the second filling time period 169 in order to supply a second filling amount 171 of washing liquid 129 to the lye container 105, wherein the second filling level 171 of the washing liquid 129 in the lye container 105 is at least high enough after the second filling time period 169 that the lower area 173 of the laundry tub 107 is filled with washing liquid 129. For this, see Figure 7 Description.

[0114] The control device 119 is configured to activate the tub drive device 109 during the second rotation time period 175 after the second filling time period 169 to rotate the laundry tub 107 at different rotation speeds so as to achieve heating of the laundry in the laundry tub 107 by contact with the washing liquid 129. For a specific rotation curve of the laundry tub 107 during the second rotation time period 175, refer to the following description of the laundry tub 107. Fig. 9 Description.

[0115] Even in Figure 8 Not shown, there is also a mixing time period after the second rotation time period 175, during which the washing liquid supply device 118-1 is activated to supply another filling amount of washing liquid 129 to the lye container 105, and during which the pump 117 of the clothing care device 100, which is fluidically connected to the lye container 105, is activated to pump the washing liquid 129 out of the lye container 105. During the mixing time period, the tub drive 109 can also be activated to rotate the laundry tub 107 in the first rotation direction at the fourth rotation speed curve 159 and in the second rotation direction opposite to the first rotation direction at the fifth rotation speed curve 161.

[0116] even though Figure 8 Not shown, the mixing time period is followed by a drying time period, during which the drum drive device 109 is constructed to rotate the clothing drum 107 at a drying speed so as to drive out the washing liquid 129 combined with the clothing due to the centrifugal force acting on the clothing, thereby drying the clothing.

[0117] Fig. 9 The barrel drive device 109 is shown in Figure 8 A schematic diagram of a rotation speed curve during the second rotation time period 175 of the clothing care process is shown.

[0118] from Fig. 9 It can be concluded that the rotation of the laundry tub 107 at the fourth speed curve 159 is followed by the rotation of the laundry tub 107 at the fifth speed curve 161. In particular, the ratio of the rotation of the laundry tub 107 at the fifth speed curve 161 to the rotation of the laundry tub 107 at the fourth speed curve 159 is between 2:1 and 10:1, wherein the ratio increases as the amount of detergent 129 added increases.

[0119] For more detailed information about the fourth speed curve 159 and the fifth speed curve 161, see Figure 6 Detailed instructions in.

[0121] The method 200 comprises a first step of activating 201 the washing liquid supply device 118-1 by means of the control device 119 during a first filling time period 137 to supply a first filling amount of washing liquid 129 to the alkaline liquid container 105, wherein, after supplying the first filling amount, a first filling level 131 of the washing liquid 129 in the alkaline liquid container 105 is at least high enough to make the inner side 133 of the laundry tub 107 contact with the washing liquid 129 so as to achieve soaking of the laundry received in the laundry tub 107 with the washing liquid 129.

[0122] The method 200 comprises a second step of activating 203 the heating element 120 by means of the control device 119 to heat the washing liquid 129 during a heating time period 139 after the first filling time period 137 , wherein the control device 119 is configured to activate the tub drive 109 to rotate the laundry tub 107 during the heating time period 139 .
