A laundry treating apparatus 1 according to another embodiment of the present invention is described below with reference to fig. 2.
As shown in fig. 2, the laundry treating apparatus 1 does not have an assembly for supplying a cleaning medium to the laundry treating chamber 10, as compared with the laundry treating apparatus 1 of the previous embodiment. Specifically, the laundry treating apparatus 1 is not provided with the water inlet assembly 20 in the foregoing embodiment, but is provided with the laundry treating chamber 10, the foam generating device 30 and the controller 40 in the foregoing embodiment, and the respective components are the same as those in the foregoing embodiment, and are not described in detail herein. Therefore, the clothes treatment device 1 with the characteristics of the embodiment, such as clothes dryer equipment without water supply to a clothes drying barrel, can realize the foam cleaning mode described in the previous embodiment, thereby providing the clothes cleaning function for the clothes treatment equipment without the traditional water washing function, meeting the differentiated cleaning requirements of users for different fabrics and different scenes and improving the user experience.
According to some embodiments of the present invention, the laundry treating apparatus 1 includes a mixing unit 50, a first liquid supply device 60, a second liquid supply device 70, a pipeline 80, and a foam dispensing device 90, wherein functions and structures of the mixing unit 50, the first liquid supply device 60, the pipeline 80, and the foam dispensing device 90 are the same as those of the previous embodiments, and are not repeated herein.
In some embodiments, the second liquid supply 70 includes a dissolution medium storage chamber adapted to store a dissolution medium. The dissolution medium storage chamber may be a water storage box (for example, a water storage box for condensing water in a clothes dryer) of the clothes treatment device 1, or an external water storage box for providing water by a user, the dissolution medium may be water, the water may be collected into the water storage box by a pump in the clothes treatment device 1, or the water for generating foam may be manually added into the water storage box by the user.
In other embodiments, the laundry treating apparatus 1 further comprises a medium supply assembly dedicated to supplying the dissolution medium to the mixing unit 50, the medium supply assembly comprising an input and an output connected to an external medium source, wherein the second liquid supply device 70 may be a valve connected between the output of the medium supply assembly and the first interface of the mixing unit 50, and the opening and closing of the valve is controlled to control the on-off of the water path between the medium supply assembly and the mixing unit 50. The medium provided by the medium supply assembly may be water, an acidic solution, an alkaline solution, or an organic solvent. In this embodiment, the laundry treating apparatus 1 does not have the water inlet assembly 20 for supplying the cleaning medium to the laundry treating chamber 10 therein, but has the medium supplying assembly adapted to supply only the dissolving medium to the mixing unit 50. Thus, the medium supply assembly may provide the dissolution medium outside the laundry treating apparatus 1 to the mixing unit 50, so that a pre-mixing operation of laundry treating agents may also be achieved in this type of laundry treating apparatus 1, facilitating the generation of a dense foam for the foam cleaning process in the subsequent foam generating device 30.
In addition, in some embodiments, the laundry treatment apparatus 1 may further include a functional device, specifically, at least one or more of an atomizing device, a steam device, a drying device, a sterilizing device, and a fan device.
A method for controlling the laundry treating apparatus 1, which is performed by the control unit 40 of the laundry treating apparatus 1 of the present invention, is described below with reference to fig. 3 to 5.
The control method of some embodiments as shown in fig. 3 is applicable to a laundry treating apparatus 1 having a laundry treating chamber 10, a water inlet assembly 20, a foam generating device 30, and a control unit 40. The laundry treating apparatus 1 may be a washing machine or a washing and drying machine, and will be described below by taking the washing machine as an example.
The method comprises the following steps: s300, determining that the water inlet assembly is closed, and controlling the foam generating device to be opened.
Here, the water inlet assembly 20 is used to supply the cleaning medium to the laundry treating chamber 10, and when the washing machine performs a water washing function, the water inlet assembly 20 delivers tap water to the dispensing device of the washing machine and the laundry treating chamber 10, and the laundry removes stains under the mechanical force provided by the washing water and the laundry treating chamber 10. The foam generating device 30 is used for generating foam required for foam cleaning, and the foam enters the clothes treating cavity 10 of the washing machine to participate in the cleaning process after the foam generating device 30 is started. In this embodiment, the water inlet assembly 20 needs to be turned off before the foam generating means 30 is turned on, so that no water outside the laundry treating chamber 10 is introduced into the laundry treating chamber 10 during the foam cleaning process, and thus the foam cleaning process can be performed under an anhydrous or micro water environment. Since the foam itself also has a certain moisture, a water film or water drop may be formed on the inner wall of the laundry treating chamber 10 and flow to the bottom of the laundry treating chamber 10 during the cleaning process, in order to ensure a water-free or micro-water environment during the cleaning process, the drain assembly of the washing machine may be continuously or intermittently opened to drain the moisture possibly accumulated in the laundry treating chamber 10, so that the water amount in the tub cannot form a water level having a certain height in the conventional water washing manner, for example, the water level in the tub is 1 cm above the lowest point of the laundry treating chamber 10, to form a water-free or micro-water environment in the laundry treating chamber 10 in the embodiment of the disclosure.
Thus, according to the control method of the embodiment of the present invention, the laundry treating apparatus 1 can clean laundry to be treated with bubbles generated from the laundry treating agent in an anhydrous or micro water environment. The cleaning process does not need the addition of washing water, does not need the combination of the washing water and the mechanical force of the rotation of the clothes treatment cavity for decontamination in the traditional washing mode, and avoids the defects of clothes winding deformation, color fading, color mixing and the like. The foam which is dense fully wraps the clothes and is continuously broken in the cleaning process, the foam permeates into the fabric to decompose and strip stains on the surface of the fabric, the decontamination component is fully contacted with the clothes, the mechanical force generated by the breaking of a large amount of foam further improves the cleaning capacity, and compared with the traditional washing mode, the clothes are higher in washing degree, and particularly have better cleaning effect on fabrics made of specific materials and stubborn stains, and the user experience is good.
In other embodiments, as the control method shown in fig. 4, after step S300, the method further includes:
s302, determining that the foam generating device is started for a first preset time period, and controlling the foam generating device to be closed.
Here, the duration of the foam cleaning is generally determined based on the load of the laundry, the type of stain, the material of the laundry, etc., and in a typical cleaning procedure, the foam cleaning is generally continued for 10 to 15 minutes, and the heavy load and the stubborn stain may be continued for 20 to 30 minutes. In general, when the foaming capacity of the foam generating device 10 is substantially unchanged, the longer the foam generating device 10 is turned on, the larger the amount of foam output to the laundry. In this embodiment, since it is necessary to consider the time required for the entire break of the foam, the duration of the foam output to the laundry is less than the total duration of the foam cleaning duration, that is, the first preset duration may be determined based on the load amount of the laundry, the type of soil, the material of the laundry, and the like and less than the duration of the washing. When the foam generating device 10 is turned on for a first predetermined period of time, the foam generating device 10 is turned off to enter a foam elimination stage, and the foam cleaning process is ended after the foam is completely dissipated.
In some embodiments, the method further comprises: s304, controlling the clothes treatment cavity 10 to perform first rotation at a first rotation speed, wherein the first rotation speed is smaller than a rotation speed threshold value.
Here, the step of rotating the laundry treating chamber 10 may be between the steps S302 or after the steps S302, or may be at least partially overlapped with the steps S302 in time. Specifically, in some embodiments, the laundry treatment chamber 10 may be rotated before foam cleaning begins, which may cause the laundry within the chamber to be shaken off before cleaning, facilitating subsequent foam output onto the laundry to cover more of the laundry surface. In other embodiments, the laundry treatment chamber 10 may be rotated after the foam stops being output to the laundry treatment chamber 10. Since the disturbance of the air flow occurs after the rotation of the laundry treating chamber 10, and the foam is generally light and fragile, the disturbed air flow may cause a loss of the foam and may fall onto the door of the laundry treating apparatus 1, resulting in insufficient foam utilization, the restarting of the rotation of the chamber after the output of the foam is completed may avoid this. In still other embodiments, the laundry treatment chamber 10 may rotate while the foam generating device 10 outputs foam, so that the laundry continuously tumbles under the action of the rotation of the chamber, at which time the foam on the laundry surface may cover more laundry surface as the laundry tumbles, at which time the continuous input of some foam may supplement the foam loss in the laundry tumbles, ensuring sufficient foam supply and wrapping the laundry, ensuring a clean effect.
In this embodiment, since the foam has a fragile characteristic, the first rotation speed at which the laundry treating chamber 10 rotates is set to a rotation speed lower than a certain rotation speed threshold. The rotation speed threshold may be selected according to a specific application scenario, and may be lower than the rotation speed of the laundry treatment chamber 10 in the process of dewatering, rinsing and/or conventional laundry treatment. For example, the rotation speed threshold value may be set to be less than 400rpm and greater than 300rpm, 100rpm, 55rpm, 40rpm, 30rpm, or the like, which is not particularly limited by the present invention. In some embodiments, the speed of rotation of the laundry treatment chamber 10 may be varied in stages, such as the first stage rotating at 30rpm, the second stage rotating at 50rpm, etc., so long as the rotational speed of the laundry treatment chamber 10 is less than the rotational speed threshold value at any stage of rotation, which is not limited by the present invention.
In some embodiments, the laundry treatment device 1 has functional means, for example at least one or more of an atomizing device, a steam device, a spraying device, a drying device, a dosing device, a sterilizing device, a fan device. In this embodiment, the method further comprises: s306, controlling the clothes treatment cavity to perform first rotation and starting a functional device of the clothes treatment device.
Here, the functions provided by the various functional devices may be combined with the foam cleaning process to achieve a further technical effect. For example, the atomization device is started to moisten clothes and then foam is output for cleaning, so that the seepage force of the decontamination component on the fabrics is stronger, and the cleaning effect is improved; for another example, by turning on the steaming device at the later stage of foam cleaning, the dirt and decontamination components remaining on the surface of the fabric can be removed, and the residue can be reduced.
In some embodiments, the method further comprises: s308, determining that the first rotation satisfies the second preset time period, and controlling the laundry treating chamber 10 to stop rotating.
Here, after the fabric in the laundry treating chamber 10 is tumbled in the foam for a second preset period of time, stains on the surface of the fabric are decomposed and peeled off, and at this time, a foam cleaning process can be completed, and the laundry treating chamber 10 is controlled to be stationary so that the residual foam is broken and adapted to take out the laundry by a user. The second preset time period may be determined according to the amount of foam and the washing requirement, and in general, the second preset time period should satisfy the time requirement that the laundry is fully contacted with the foam, and most of the foam breaks, stains are decomposed and peeled, and the second preset time period may be 15 minutes, 20 minutes, 30 minutes, 45 minutes, 60 minutes, or the like, and the present invention is not limited to the specific time period.
In some embodiments, the method further comprises: s310, controlling the clothes treatment cavity 10 to perform second rotation at a second rotation speed; wherein the second rotational speed is greater than the rotational speed threshold.
Here, after the fabric of the laundry treating chamber 10 is tumbled in the foam for a second preset period of time, stains on the surface of the fabric are decomposed and peeled off, and at this time, the foam cleaning process can be completed. Since the foam itself contains a certain amount of moisture and there may be a case where the soil-removing component or the soil remains on the surface of the fabric, the step of performing the second rotation at the second rotation speed is added to further remove the soil-removing component or the soil remains in this embodiment. Specifically, the second rotation speed is higher than the rotation speed threshold, for example, the second rotation speed rotates at a dehydration rotation speed, and the decontamination component or dirt can be separated from the surface of the fabric along with the action of centrifugal force of water, so that the washing degree of clothes is improved.
In some embodiments, the method further comprises: determining that the laundry treating chamber 10 performs a first rotation, and controlling the water level in the laundry treating chamber 10 to be lower than a water level threshold; wherein the water level threshold is equal to or less than 1 cm above the lowest point of the laundry treatment chamber 10.
Here, during the foam cleaning process, since the foam itself also contains water, a water film or water drop may be formed on the inner wall of the laundry treating chamber 10 and flow to the bottom of the laundry treating chamber 10 as the cleaning process proceeds, and in order to ensure a water-free or micro-water environment during the cleaning process, the water level in the laundry treating chamber 10 may be controlled to be lower than the water level threshold value by continuously or intermittently opening the water draining assembly of the washing machine. In addition, auxiliary functions such as spraying and spraying can be added in foam cleaning, and newly added water is required to be discharged in time at the moment, so that the water level in the clothes treatment cavity 10 is controlled to be lower than a water level threshold value. In this embodiment, the water level threshold may be set to be equal to or less than 1cm above the lowest point of the laundry treating chamber 10. Generally, the laundry machine forms a liquid level of a certain water level height in the laundry treating chamber 10 during cleaning and rinsing, for example, a water level height of 1cm above the lowest point of the laundry treating chamber 10. Therefore, this embodiment of the present invention always controls the water level in the laundry treating chamber 10 to be lower than the water level threshold value during the cleaning process, so that the cleaning process cannot perform operations such as water inlet, rinsing, etc., and timely eliminates moisture provided by functions such as spraying, sprinkling, etc., thereby maintaining a non-aqueous or micro-aqueous environment during the cleaning process.
The control method of still other embodiments as shown in fig. 5 is applicable to the laundry treating apparatus 1 having the laundry treating chamber 10, the foam generating device 30 and the control unit 40 without the water inlet assembly 20. The laundry treating apparatus 1 may be a dryer or a dry cleaner.
The method comprises the following steps: s400, performing a first laundry treatment operation, the first laundry treatment operation including: and controlling the foam generating device to be started.
In the prior art, the conventional water washing requires the supply of washing water to the laundry treating chamber 10, and the laundry removes stains by the mechanical force provided by the washing water and the laundry treating chamber 10. In contrast, the laundry treating apparatus 1 of this embodiment does not have the water inlet assembly 20 for feeding water into the laundry treating chamber 10, and thus the laundry treating apparatus 1, such as a clothes dryer, is generally not capable of performing a washing operation. In this embodiment, since the laundry treating apparatus 1 has the foam generating device 30, the foam generating device 30 is used to generate foam required for foam cleaning, so by controlling the foam generating device 30 to be turned on, the generated foam will enter the laundry treating chamber 10 of the clothes dryer to participate in the cleaning process, thus, such laundry treating apparatus 1 as clothes dryer has the function of cleaning clothes, the dense foam fully wraps the clothes and is continuously broken in the cleaning process, the dirt penetrating into the fabric is decomposed and peeled off, the decontamination component is fully contacted with the clothes, and the mechanical force generated by the breaking of a large amount of foam further improves the washing capability, compared with the conventional water washing method, especially has better cleaning effect on the fabric of specific material and stubborn dirt, and the user experience is good.
In some embodiments, the method further comprises:
s402, determining that the foam generating device 30 is opened for a first preset time period, and controlling the foam generating device 30 to be closed.
S404, controlling the laundry treating chamber 10 to perform a first rotation at a first rotation speed, wherein the first rotation speed is less than a rotation speed threshold.
S406, controlling the laundry treating chamber 10 to perform the first rotation and turning on the functional device of the laundry treating apparatus 1.
S408, determining that the first rotation satisfies the second preset time period, and controlling the laundry treating chamber 10 to stop rotating.
The specific contents of the above steps are the same as steps S302, S304, S306, S308, and will not be described here again.
