Description

Technical Field

[0001] The present invention belongs to the technical field of washing machines, and more specifically, relates to a laundry treatment device and a control method thereof. Background Art

[0002] As laundry treatment devices are used more and more frequently, many existing laundry treatment devices are provided with an automatic dosing module, which automatically doses a corresponding amount of laundry treatment agent according to the weight of the laundry or the water inlet level. This can not only save the process of the user dosing the laundry treatment agent and improve the user experience, but also, on the other hand, the accuracy of automatic dosing is relatively high compared with manual dosing by the user.

[0003] Therefore, how to ensure the washing effect on the basis of automatic dosing, while at the same time reducing the concentration of the laundry treatment agent in the rinse water and avoiding excessive residue of the laundry treatment agent, has become an urgent problem to be solved.

[0004] In view of this, the present invention is specifically proposed. Summary of the Invention

[0005] An object of the present invention is to overcome the deficiencies of the prior art and provide a laundry treatment device, which determines the total dosing amount by summing up the dosing amounts of the laundry treatment agent corresponding to the soiling degrees of each single piece of laundry to be washed, so as to more accurately control the dosing amount of the laundry treatment agent on the premise of ensuring the washing effect.

[0006] Another object of the present invention is to provide a control method for a laundry treatment device.

[0007] To achieve the first object of the invention, the following technical solution is adopted:

[0008] A laundry treatment device, comprising:

[0009] A first acquisition module, configured to acquire the soiling degree information of any single piece of laundry to be washed;

[0011] An automatic dosing module, configured to receive the feedback from the control module and dose the laundry treatment agent according to the amount.

[0012] Further, the dosing amount of the laundry treatment agent corresponding to the soiling degree of the single piece of laundry to be washed is determined according to the total wearing time within two washing intervals and the dosing amount of the laundry treatment agent corresponding to the unit soiling degree;

[0013] The unit soiling degree is the soiling degree value of the laundry at an interval-set wearing time.

[0014] Further, the first acquisition module interacts with the first image acquisition module to obtain the total wearing time of the clothes to be washed during the interval between two washes.

[0015] Further, it further includes:

[0016] A second acquisition module, configured to acquire special stain information of the clothes to be washed;

[0017] Based on the special stain information, the control module corrects the dosage of the clothing treatment agent corresponding to the dirtiness of the clothes to be washed;

[0018] The special stain information includes the type of special stain and the area of the special stain.

[0019] Further, it further includes a voice module, configured to remind the user to deliver the clothes to be washed piece by piece when the door of the clothing treatment device is opened.

[0020] To achieve the second invention object, the present invention adopts the following technical solutions:

[0021] A control method for a clothing treatment device, including:

[0022] Acquire the dirtiness information of any single piece of clothes to be washed in this wash;

[0023] Determine the dosage of the clothing treatment agent corresponding to any single piece of clothes to be washed according to the dirtiness information of the clothes, and sum up the dosages of the clothing treatment agents corresponding to each single piece of clothes to be washed to obtain the total dosage of the clothing treatment agent for this wash;

[0024] Dispense the clothing treatment agent according to the dosage.

[0025] Further, the dosage of the clothing treatment agent corresponding to any single piece of clothes to be washed is determined according to the total wearing time during the interval between two washes and the dosage of the clothing treatment agent corresponding to the unit dirtiness.

[0026] Further, acquire the concentration of the clothing treatment agent in the rinse water during the first rinse in this rinsing process, and adjust the dosage of the clothing treatment agent corresponding to the unit dirtiness of all current clothes for the next wash according to the concentration of the clothing treatment agent.

[0027] Further, when the concentration of the clothing treatment agent is greater than the first set value, reduce the dosage of the clothing treatment agent corresponding to the unit dirtiness;

[0028] When the concentration of the clothing treatment agent is less than the second set value, increase the dosage of the clothing treatment agent corresponding to the unit dirtiness;

[0029] When the concentration of the clothing treatment agent is less than or equal to the first set value and greater than or equal to the second set value, maintain the current dosage of the clothing treatment agent corresponding to the unit dirtiness.

[0030] Further, when any single piece of clothing participates in washing for the first time in the historical washing process of this washing, if the concentration of the clothing treatment agent in the rinsing water during the first rinsing is greater than the first set value or less than the second set value, only the dosage of the clothing treatment agent corresponding to the unit soiling degree of the clothing that participates in washing for the first time is adjusted.

[0031] Further, in any washing process, if the concentration of the clothing treatment agent in the rinsing water during the first rinsing is within the set range, the dosage of the clothing treatment agent corresponding to the unit soiling degree of the currently washed clothing remains a determined value.

[0032] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0033] 1. The present invention determines the actual dosage of the clothing treatment agent by summing up the dosages of the clothing treatment agent corresponding to the soiling degrees of each single piece of clothing to be washed, and further controls the dosage of the clothing treatment agent more precisely. On the premise of ensuring the washing effect, it can also ensure economy and avoid excessive residue of the clothing treatment agent.

[0034] 2. The present invention adjusts the dosage of the clothing treatment agent corresponding to the unit soiling degree of the clothing by obtaining the concentration of the clothing treatment agent in the rinsing water during the first rinsing in the rinsing stage, and further optimizes the dosage of the clothing treatment agent in the next washing, so as to further avoid excessive residue of the clothing treatment agent on the premise of ensuring the washing effect.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0041] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention.

[0042] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] The present invention provides a laundry treatment device, including:

[0044] A first acquisition module for acquiring the dirtiness information of any single piece of laundry to be washed;

[0045] A control module for summing up the dosages of laundry treatment agents corresponding to the dirtiness of each single piece of laundry to be washed and feeding back the sum to an automatic dosing module;

[0046] The automatic dosing module for receiving the feedback from the control module and dosing the laundry treatment agent according to the dosage.

[0047] Considering that for the same piece of clothing, both the clothing material and the clothing weight are determined values, and the dirtiness is a variable, the dosage of the laundry treatment agent required for this piece of clothing during each washing needs to consider the influence of the dirtiness. When the dirtiness is relatively large, the corresponding dosage of the laundry treatment agent is relatively large; when the dirtiness is relatively small, the corresponding dosage of the laundry treatment agent is also relatively small.

[0048] On the other hand, although the water temperature can also affect the effect of the laundry treatment agent on dirt, considering that for the same piece of clothing, users usually wash it using the same washing program, and the water temperature corresponding to the same washing program is the same. For example, for a down jacket, if the user uses the down wash program for it, they will not use a quick wash or other programs for subsequent washing; for ordinary clothes, if the user uses a standard wash or other washing programs, they will also use the standard wash for subsequent washing. Therefore, in the present invention, only the dirtiness is used as the influencing factor for the dosage of the laundry treatment agent.

[0049] In view of this, the present invention sums up the dosage of the laundry treatment agent corresponding to the dirtiness of each single piece of laundry to be washed to determine the actual dosage of the laundry treatment agent to ensure the accuracy of the dosage.

[0050] Specifically, the dosage of the laundry treatment agent corresponding to the dirtiness of a single piece of laundry to be washed is determined according to the wearing time and the dosage of the laundry treatment agent corresponding to the unit dirtiness, and the unit dirtiness is the dirtiness value of the laundry at intervals of the set wearing time.

[0051] For example, if the set wearing time is 1 day, then for each day the user wears the clothes, there is a corresponding dirtiness value, and if the dosage of the laundry treatment agent corresponding to one dirtiness value is 1 ml, then when the user wears the clothes for three days, the dosage of the laundry treatment agent corresponding to this piece of laundry to be washed is 3 ml; when the user wears the clothes for five days, the dosage of the laundry treatment agent corresponding to this piece of laundry is 5 ml.

[0052] After obtaining the dosage of the laundry treatment agent corresponding to each piece of laundry to be washed, the control module sums them up to obtain the dosage of the laundry treatment agent required for the main washing stage this time, and then the automatic dosing module doses according to the feedback result of the control module by quantity.

[0053] In an embodiment of the present invention, the first acquisition module interacts with the first image acquisition module to obtain the total wearing time of the laundry to be washed during the interval between two washes.

[0054] To ensure the possibility of the first image acquisition module obtaining the user's wearing information, the first image acquisition module of the present invention can be set at the user's door. When the user enters or exits the door or passes by the door, the first image acquisition module can obtain the user's wearing information, and the first acquisition module can update the total wearing time of the corresponding clothes.

[0055] Furthermore, in this embodiment, in addition to the first acquisition module, the laundry treatment device is also provided with a second acquisition module for the user to obtain the special stain information of the laundry to be washed. The special stain information includes parameters such as the type of special stain and the area of the special stain. The types of special stains include lipstick marks, colored pen marks, wine stains, etc., which can be obtained by the user directly inputting, and the area of the special stain can be obtained by the second acquisition module directly collecting an image of the laundry to be washed.

[0056] The control module can modify the dosage of the laundry treatment agent corresponding to the soiling degree of the laundry to be washed based on the special stain information. For example, when the special stain type is cooking oil stain and the special stain area is large, the control module can set the correction coefficient to 1.5; when the special stain type is lipstick mark and the special stain area is small, the control module can set the correction coefficient to 1.2.

[0057] In another embodiment of the present invention, the laundry treatment device is further provided with a third acquisition module for acquiring the travel information of the user, and the control module can modify the dosage of the laundry treatment agent corresponding to the laundry to be washed based on the travel information.

[0058] For example, if the total wearing time of the current laundry within two washing intervals is 3 days, its set wearing time is 1 day, and the dosage of the laundry treatment agent corresponding to the unit soiling degree is 1 ml, then the dosage of the laundry treatment agent corresponding to the soiling degree of the current laundry is 3 ml. However, based on the travel information of the user, it is obtained that the user passes through areas with large dust such as construction sites. At this time, the control module determines the correction coefficient to be 1.2, that is, the actual dosage of the laundry treatment agent corresponding to the soiling degree of the current laundry is 3 * 1.2 = 3.6 ml.

[0059] Or, when the third acquisition module obtains that the user stays in places such as gyms and basketball courts for a long time, it is determined that the user may sweat a lot. At this time, the control module determines the correction coefficient to be 1.5, that is, the actual dosage of the laundry treatment agent corresponding to the soiling degree of the current laundry is 3 * 1.5 = 4.5 ml.

[0060] Or, the third acquisition module can also be used to acquire the weather information corresponding to the wearing time. Correspondingly, the control module can also modify the dosage of the laundry treatment agent corresponding to the soiling degree of the laundry to be washed according to the weather information.

[0061] For example, if the total wearing time of the current laundry within two washing intervals is 3 days, its set wearing time is 1 day, and the dosage of the laundry treatment agent corresponding to the unit soiling degree is 1 ml, then the dosage of the laundry treatment agent corresponding to the soiling degree of the current laundry is 3 ml. However, based on the weather information, the outdoor temperature when the user goes out is 20 °C. At this time, the control module determines the correction coefficient to be 1.0, that is, the actual dosage of the laundry treatment agent corresponding to the soiling degree of the current laundry is 3 * 1.0 = 3.0 ml.

[0062] Or, when the outdoor temperature when the user goes out is 30 °C, considering that the user may sweat, the control module determines the correction coefficient to be 1.3, that is, the actual dosage of the laundry treatment agent corresponding to the soiling degree of the current laundry is 3 * 1.3 = 3.9 ml.

[0063] Preferably, the control module of this embodiment can comprehensively judge the dosage of the laundry treatment agent corresponding to the soiling degree of the laundry to be washed through factors such as the weather information and travel information corresponding to the wearing time.

[0064] In another embodiment of the present invention, considering that the dirtiness of the clothing is divided into two aspects, internal and external. For example, when the user sweats a lot, the dirtiness inside the clothing is relatively large, but this part of the dirt is not directly reflected on the surface of the clothing. In this embodiment, the dirt information of this part is obtained through parameters such as the travel information and weather information obtained by the third acquisition module; for the dirtiness on the outside of the clothing, such as obvious special stains, etc., in this embodiment, it can be directly obtained by the second acquisition module.

[0065] Based on the feedback information of the first acquisition module, the second acquisition module, and the third acquisition module, the control module corrects the dosage of the clothing treatment agent corresponding to the dirtiness of the clothing to be washed, and finally forms the actual dosage corresponding to the dirtiness of the clothing to be washed, so as to achieve more precise control of the dosage of the clothing treatment agent and be more economical.

[0066] Furthermore, in this embodiment, to facilitate the second acquisition module to obtain special stain information in the form of image information, the clothing treatment device is also provided with a voice module. When the door of the clothing treatment device is opened, the voice module starts to work, reminding the user to put the clothing to be washed into the inner drum piece by piece.

[0067] Correspondingly, the clothing treatment device of the present invention is also provided with a first sensor for detecting whether the door is opened. The first sensor is arranged at the door lock of the clothing treatment device. For example, the first sensor can be a distance measuring sensor. When it is detected that the distance between the door and the box body of the clothing treatment device is greater than the set distance, it is determined that the door is opened at this time, and the voice module starts to work.

[0068] Furthermore, when the door of the clothing treatment device is opened, the control module of the present invention determines that the user has a washing tendency and controls the first acquisition module to start working to avoid missing the clothing to be washed.

[0069] Considering that there are two situations, washing and picking up clothes, when the door of the clothing treatment device is opened. Therefore, in another embodiment of the present invention, when the first sensor detects that the door is opened and the weight sensor feeds back that the current weight is the initial weight, it is determined that the user has a washing tendency, and the control module controls the first acquisition module to start working.

[0070] When the user picks up clothes, there are clothes that have been washed in the inner drum. At this time, the feedback information of the weight sensor shows that the current weight is greater than the initial weight. Therefore, when the door is opened but the weight sensor feeds back that the current weight is greater than the initial weight, the clothing treatment device determines the current situation as the user picking up clothes, and at this time, the first acquisition module does not work.

[0071] As Figure 1-2 shown, the present invention also provides a control method for a clothing treatment device, which specifically includes:

[0072] Obtain the dirtiness information of the laundry to be washed for any single piece in this washing.

[0073] Determine the dosage of the laundry treatment agent corresponding to any single piece of laundry to be washed according to the dirtiness information of the laundry, and sum up the dosages of the laundry treatment agent corresponding to each single piece of laundry to be washed to obtain the total dosage of the laundry treatment agent for this washing.

[0074] Dispense the laundry treatment agent according to the dosage.

[0075] Among them, the dosage of the laundry treatment agent corresponding to any single piece of laundry to be washed is determined according to the total wearing time within the interval between two washings and the dosage of the laundry treatment agent corresponding to the unit dirtiness.

[0076] In an embodiment of the present invention, the laundry treatment device obtains the concentration of the laundry treatment agent in the rinsing water during the first rinsing in this rinsing process, and adjusts the dosage of the laundry treatment agent corresponding to the unit dirtiness for all current laundry during the next washing according to the obtained concentration of the laundry treatment agent.

[0077] Specifically, when the concentration of the laundry treatment agent is greater than the first set value, the control module determines that the current concentration of the laundry treatment agent is relatively high and there is a waste phenomenon, and reduces the dosage of the laundry treatment agent corresponding to the unit dirtiness.

[0078] When the concentration of the laundry treatment agent is less than the second set value, the control module determines that the current concentration of the laundry treatment agent is relatively low and the laundry may not be washed thoroughly, and increases the dosage of the laundry treatment agent corresponding to the unit dirtiness.

[0079] When the concentration of the laundry treatment agent is less than or equal to the first set value and greater than or equal to the second set value, the control module determines that the current laundry treatment agent can avoid waste while ensuring the washing effect, so the dosage of the laundry treatment agent corresponding to the current unit dirtiness is maintained.

[0080] In this embodiment, the concentration of the laundry treatment agent in the rinsing water is compared with the set range to realize the dynamic adjustment of the dosage of the laundry treatment agent corresponding to the unit dirtiness, so as to continuously optimize the dosage of the laundry treatment agent, ensure the washing effect and ensure the economy at the same time.

[0081] Furthermore, in the present invention, the water inlet volume in the main washing stage and the water inlet volume in the rinsing stage are preferably fixed values, that is, they are not adjusted according to factors such as the weight of the laundry, so as to ensure the washing effect of the dosage of the laundry treatment agent dispensed based on the dirtiness information of the present invention, and avoid the concentration of the laundry treatment agent being too low when the water inlet volume is large, which affects the washing effect; on the other hand, it can also ensure the accuracy when comparing the concentration of the laundry treatment agent in the rinsing water.

[0082] In an embodiment of the present invention, when any single piece of clothing participates in washing for the first time in the history of the current washing process, that is, when the control module does not obtain the dosage of the clothing treatment agent corresponding to the previous unit dirtiness, the control module determines the dosage of the clothing treatment agent according to the current weight of the clothing and its dirtiness, and records the basic dosage of the clothing treatment agent corresponding to the unit dirtiness. For example, according to the feedback information of the first acquisition module, based on the wearing time of the current clothing being 3 days and the set wearing time being 1 day, if the basic dosage determined by the control module is 6 ml, then the basic dosage of the clothing treatment agent corresponding to the unit dirtiness is 2 ml.

[0083] In the subsequent washing process of the current clothing, if the concentration of the clothing treatment agent in the rinse water is greater than the first set value or less than the second set value during the first rinsing, that is, when it is not within the set range, the control module increases or decreases the dosage of the clothing treatment agent corresponding to its unit dirtiness on the basis of 2 ml.

[0084] In another embodiment of the present invention, when there is clothing that participates in washing for the first time in the current washing, if the concentration of the clothing treatment agent in the rinse water is greater than the first set value or less than the second set value during the first rinsing, considering that the dosage of the clothing that participates in washing for the first time is the basic dosage and has not been dynamically adjusted yet, in order to avoid affecting the accuracy of the dosage of the clothing treatment agent corresponding to the unit dirtiness of the remaining clothing, at this time, the dosage of the clothing treatment agent corresponding to the unit dirtiness of the remaining clothing is not adjusted, and only the dosage of the clothing treatment agent corresponding to the unit dirtiness of the clothing that participates in washing for the first time is adjusted. Specifically,

[0085] When the concentration of the clothing treatment agent is greater than the first set value, the control module reduces the dosage of the clothing treatment agent corresponding to the unit dirtiness;

[0086] When the concentration of the clothing treatment agent is less than the second set value, the control module increases the dosage of the clothing treatment agent corresponding to the unit dirtiness.

[0087] There is a situation that if the user washes only one piece of clothing each time, the dosage of the clothing treatment agent corresponding to the unit dirtiness of this piece of clothing after multiple dynamic adjustments should be the optimal value. However, if this piece of clothing is washed together with other clothing and the concentration of the clothing treatment agent in the rinse water is greater than the first set value or less than the second set value during the first rinsing, the control module will still adjust the dosage of the clothing treatment agent corresponding to its unit dirtiness. At this time, the control module adjusts the optimal value to a non-optimal value, which has a counterproductive effect.

[0088] Therefore, to avoid the above situation, in any washing process, if the concentration of the clothing treatment agent in the rinse water is within the set range during the first rinsing, the dosage of the clothing treatment agent corresponding to the unit dirtiness of the currently washed clothing remains a determined value and will not be adjusted subsequently to avoid ineffective adjustment.

[0089] The present invention determines the actual dosage of the laundry treatment agent by summing up the dosages of the laundry treatment agent corresponding to the soiling degrees of each single piece of laundry to be washed, thereby enabling more precise control of the dosage of the laundry treatment agent. On the premise of ensuring the washing effect, it can also ensure economy and avoid excessive residue of the laundry treatment agent.

[0090] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art of this patent can make some changes or modifications to equivalent embodiments by using the technical content prompted above within the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, as long as it does not deviate from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the scope of the present invention.
