Description

Technical Field

[0001] This invention relates to the field of clothing treatment equipment, and more particularly to a clothing treatment device and a method for washing blood-stained clothing. Background Art

[0002] For clothing with stains, such as menstrual blood, if it is washed or treated promptly, it will adhere firmly to the clothing, making it difficult to wash, and the longer it sits, the more difficult it becomes to wash.

[0003] Especially for clothes with blood stains, such as menstrual blood, washing them during the user's rest time will affect their rest. If they are not washed or treated in time, the blood stains will solidify and adhere firmly to the clothes, making them difficult to wash. The longer the stains remain, the more difficult they become to wash.

[0004] Currently, among the publicly available garment cleaning equipment with scheduled washing technology, there is no specific and effective washing method for stains, especially menstrual blood stains. Menstrual blood not only contains normal blood components but also fibrinolytic enzymes, endometrial fragments, cervical mucus, and other components, increasing the difficulty of washing. Existing washing methods are usually ineffective in removing these stains. Furthermore, if the waiting time after scheduling a wash is long, the blood stains will coagulate, and the longer the time, the more difficult the stains become to remove. Summary of the Invention

[0005] In view of this, the present invention discloses a clothing treatment device and a washing method for blood-stained clothing, in order to solve the problem that blood stains on clothing are difficult to wash due to coagulation during the waiting period for an appointment.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0057] To address the problem of difficulty in washing blood stains (menstrual blood as an example below) on clothing during the reservation waiting process due to coagulation, this embodiment discloses a washing method for blood-stained clothing (or a reservation control method for clothing treatment equipment), combined with... Figure 1 The method includes S1~S2, wherein:

[0058] S1, when the garment processing equipment is in reservation mode, determine the amount of free time between the start time of the reservation and the start time of the reserved garment processing program.

[0059] S2 adjusts the washing parameters of the scheduled laundry processing program based on the amount of available time.

[0060] Bloodstained clothing, especially menstrual blood-stained clothing, needs to be washed promptly, but this is often not possible due to various objective reasons. This embodiment provides a scheduled washing control method, which not only avoids washing during rest hours and disturbing the user's rest, but also frees women's hands from washing clothes in cold water during menstruation, improving the user experience. This method aims to utilize the waiting time after scheduling to adjust washing parameters (e.g., pre-washing treatment of bloodstained clothing to remove some of the unconsolidated blood stains and slow down the congealing of blood stains), avoiding the blood stains from solidifying during the waiting process, which would make washing difficult and leave marks.

[0061] Further optionally, in one implementation of this embodiment, the scheduled laundry processing program has different washing stages, and S2 adjusts the washing parameters of the scheduled laundry processing program according to the amount of available time, including:

[0062] Adjust the washing time for each stage of garment processing based on available time.

[0063] In this embodiment, considering that menstrual blood contains more fibrinolytic enzymes, endometrial fragments, and cervical mucus than normal blood, and that menstrual blood presents different states at different times, a segmented washing method is adopted to wash blood-stained clothing. Different washing operations are performed at different stages to enhance the washing effect on blood-stained clothing and reduce clothing marks. At the same time, the washing time of each stage is adjusted by utilizing the idle waiting time after the appointment. During the waiting process, the blood-stained clothing is treated to remove some components and slow down the coagulation of blood stains, which helps the subsequent washing and increases the cleaning effect.

[0064] According to the inventor's targeted analysis and research, menstrual blood contains not only normal blood components but also fibrinolytic enzymes, endometrial fragments, cervical mucus, and other substances, increasing the difficulty of washing. When blood is not completely coagulated, it is soluble in water and relatively easy to remove. However, as blood remains for a longer period, the ferrous iron in the heme is oxidized to ferric iron and coagulates with proteins, forming blood spots that are difficult to wash off. Improper washing methods, such as heating the water before removing protein-containing substances, can cause protein denaturation, leaving indelible stains.

[0065] Furthermore, the different washing stages include the sequential spray washing stage, soaking washing stage, and tumbling washing stage;

[0066] During the spray washing stage, the spray valve is used to control the spray valve to spray water into the washing tub to rinse the blood-stained clothes, and the drain valve is used to drain the water.

[0067] The soaking stage is used to introduce a preset amount of washing water into the washing tub to soak the blood-stained clothes, and to drain the washing water from the tub at the end of the soaking process.

[0068] The tumbling and washing stage is used to control the washing tub to rotate in both directions alternately to tumble and wash bloodstained clothes.

[0069] The tumbling and washing stage includes:

[0070] The cold water washing stage is used to tumble and wash blood-stained clothing in cold water.

[0071] In the heated washing stage, the washing water is heated to reach the first preset temperature, and the blood-stained clothes are tumbled and washed.

[0072] In this embodiment, because menstrual blood contains a certain amount of fibrinolytic enzymes in the early stage, which can dissolve fibrinogen in the blood, making menstrual blood easier to liquefy and less prone to coagulation, and because the iron in heme exists in the form of ferrous iron, which is soluble in water, and because cervical mucus is difficult to remove after soaking, a rinsing method is used for the initial treatment. In the later stage, after the blood coagulates, ferrous iron is oxidized to ferric iron, which coagulates with proteins to form blood spots. The precipitated serum contains proteins, fats, and inorganic substances. Proteins should not be heated, while fats need to be heated to dissolve and wash away. Therefore, during the initial period, a spray rinsing method is used, rinsing while draining water to remove uncoagulated blood stains, cervical mucus, and endometrial fragments. Afterwards, a certain amount of soaking is performed to slow down the action of thrombin, thereby slowing down blood coagulation. In the tumbling and washing stage, cold water is first used to wash for a certain period to remove protein components, followed by heated washing to remove fatty stains. This achieves a good removal effect on menstrual blood and prevents incomplete washing from leaving marks on clothing.

[0073] Furthermore, S2 adjusts the washing parameters of the scheduled garment processing program based on the amount of available time, including: during the soaking wash stage, spraying and rinsing the blood-stained garments at set time intervals and agitating the washing water.

[0074] In this embodiment, the washing time for each washing stage is adjusted within the scheduled waiting period to increase the cleaning effect while ensuring the washing ends on time to avoid affecting the user's drying. Specifically, the clothes placed in the tub are first sprayed with water while being drained, followed by soaking for a certain period. During soaking, the water can be sprayed and stirred at intervals to prevent blood stains from returning to the clothes and to rinse away any non-clotting serum. The washing process is carried out in the time period before the scheduled end, with the first stage using cold water and the latter stage using heated water. This slows down the coagulation of blood during the waiting period, removes some stains, and facilitates the subsequent washing, thus increasing the cleaning effect.

[0075] Furthermore, the washing duration T11 of the spray washing stage is within the range of 2 minutes or more and 6 minutes or less.

[0076] The washing time T12 during the soaking wash stage is within the range of 2 minutes or more and 10 minutes or less.

[0077] The total washing time Tz for the cold water wash and heated wash stages ranges from 15 minutes to 35 minutes.

[0078] The cold water wash duration T31 is: greater than or equal to 1 / 5Tz and less than or equal to 4 / 5Tz;

[0079] The heating wash duration T41 is greater than or equal to 1 / 5Tz and less than or equal to 4 / 5Tz.

[0080] Combination Figure 2 The overall washing process is as follows: spraying and draining for time T11 (S102), soaking in water for time T21 followed by draining (S103), cold water washing for time T31 (S104), and heated washing for time T41 (S105). This process can effectively remove menstrual blood and reduce stains on clothing. The spraying time T11 can be selected as 2-6 minutes, preferably 4-5 minutes; the soaking time T21 can be selected as 1-10 minutes, preferably 3-4 minutes; the cold water washing time T31 can be selected as 1 / 5-4 / 5 Tz, preferably 1 / 2-2 / 3 Tz; and the heated washing time T41 can be selected as 1 / 5-4 / 5 Tz, preferably 1 / 3-1 / 2 Tz. Tz is the sum of the cold water washing time T31 and the heated washing time T41, and Tz can be selected as 20-35 minutes, preferably 25 minutes.

[0081] Furthermore, in S2, the washing parameters of the scheduled laundry processing program are adjusted based on the available time, including steps A1 to A2, wherein:

[0082] A1, determine the range of the amount of free time;

[0083] A2, Adjust the washing time for each stage of garment processing according to the available time range;

[0084] As the amount of free time increases, the washing time of the spray wash stage and the soaking wash stage increases accordingly, while the total washing time Tz of the cold water wash stage and the heated wash stage decreases accordingly.

[0085] Specifically, this involves determining the range of the idle time Tk, and adjusting the parameters for each washing stage based on this range. Figure 3The washing process begins with a spray-drainage cycle (S209) to ensure thorough rinsing and reduce the residue of uncoagulated menstrual blood, cervical mucus, and endometrial fragments. The spray-drainage cycle (S12) can be adjusted based on available time (Tk) to enhance rinsing effectiveness; see Table 1 for parameter adjustment details. After rinsing, immediately immerse the garment in water for a time (S2010). During immersion, spray the garment at intervals of T5. This spraying process allows for partial water removal, water exchange, and agitation, removing any separated serum from the clothing and preventing prolonged soaking that could cause stains dissolved in the water to reappear. The immersion time (S22) can be adjusted based on available time (Tk) to enhance the dissolving effect and reduce blood coagulation; see Table 1 for parameter adjustment details. The interval (T5) can be selected from 10-60 minutes, preferably 30 minutes. After soaking, drain the water to remove the dirty wastewater. Then, refill the tank with water and tumble wash. In the initial washing stage, perform a cold water wash (S2011) to remove protein-based stains; the cold water is preferably room temperature water. After a certain cold water wash time (T32), perform a heated wash (T42) to dissolve fatty stains, thus better removing these stains and erasing marks. Fatty stains dissolve more easily at 40-50℃, so the heating temperature can be selected as 40-60℃, preferably 45-50℃. The cold water washing time T32 can be selected as 1 / 5-4 / 5Tz, preferably 1 / 2-2 / 3Tz; the heated washing time T42 can be selected as 1 / 5-4 / 5Tz, preferably 1 / 3-1 / 2Tz; the sum Tz of the cold water washing time T32 and the heated washing time T42 can be appropriately adjusted according to the amount of spare time Tk, as detailed in the parameter adjustment table in Table 1. Preferably, as the amount of spare time Tk increases, Tz should be appropriately reduced, because as the amount of spare time Tk increases, the spraying and soaking time increases accordingly, and the stain removal effect of spraying and soaking is improved, which helps with washing. Therefore, reducing Tz can also ensure the washing effect and ensure that the washing ends on time, so as not to affect the user's drying.

[0086] Table 1. Parameter Adjustment Table

[0087]

[0088] Furthermore, S1 determines the amount of free time between the start time of the reservation and the start time of the processing procedure for the reserved clothing, including steps B1 to B3, wherein:

[0089] B1, get the start time T1 and the end time T2 of the reservation, and get the washing time Tc of the reserved clothing processing program;

[0090] B2, calculate the time difference Td between the reservation end time T2 and the reservation start time T1;

[0091] B3. Calculate the difference between the time difference Td and the washing duration Tc to obtain the amount of free time.

[0092] Furthermore, before adjusting the washing parameters of the scheduled laundry processing program based on the amount of available time in S2, the method also includes steps B4 to B6, wherein:

[0093] B4 compares the amount of free time with the set margin value;

[0094] B5, when the available time is greater than or equal to the set available time value, adjust the washing parameters of the scheduled laundry processing program according to the available time; or,

[0095] B6. When the amount of idle time is less than the set amount of spare time, wash according to the original program parameters.

[0096] This embodiment calculates the time difference Td using the start time T1 and end time T2. It then calculates the spare time Tk using the time difference Td and the washing duration Tc of the scheduled laundry program. By counting down the spare time Tk, it ensures the laundry equipment starts on time at the scheduled start time and ends on time at the scheduled end time. A spare time judgment is made by comparing the spare time Tk with the set margin value Ti. If Tk ≥ Ti, it indicates there is spare time, which can be used to adjust the washing parameters of the scheduled laundry program; otherwise, there is no spare time, and the washing proceeds according to the original program parameters. The set margin value Ti can be selected from 15 min to 60 min, preferably 30 min.

[0097] Figure 2This is one illustration of the control flow of the present invention. Based on the components and characteristics of menstrual blood, this solution provides washing operations at different time periods. Freshly discharged menstrual blood contains a certain amount of plasmin, which can dissolve fibrinogen in the blood. Blood clotting is caused by the conversion of fibrinogen into fibrin, so plasmin makes menstrual blood easier to liquefy and less prone to clotting. Moreover, the iron in heme exists in the form of ferrous iron, which is soluble in water. On the other hand, cervical mucus in menstrual blood can stick to clothing and is not easy to remove. Therefore, during this period, it is advisable to rinse while spraying and draining water to wash away uncoagulated bloodstains, cervical mucus, and endometrial fragments. Secondly, thrombin converts fibrinogen into fibrin, and since thrombin is water-soluble, soaking in water can slow down the action of thrombin, thereby reducing blood clotting. After blood clotting, ferrous iron is oxidized to ferric iron, which coagulates with proteins to form blood spots. The precipitated serum contains proteins, fats, and inorganic substances. Proteins should not be heated, while fats need to be heated to dissolve and wash away. Therefore, after the initial tumbling and washing, cold water is used for a certain period of time to remove protein components, followed by heated washing to remove fatty stains. Thus, the overall washing process is as follows: spraying and draining for T11 time (S102), soaking in water for T21 time followed by draining (S103), cold water washing for T31 time (S104), and heated washing for T41 time (S105). This process effectively removes menstrual blood, reducing stains on clothing. The spraying time T11 can be selected as 2-6 minutes, preferably 4-5 minutes; the soaking time T21 can be selected as 1-10 minutes, preferably 3-4 minutes; the cold water washing time T31 can be selected as 1 / 5-4 / 5 Tz, preferably 1 / 2-2 / 3 Tz; the heated washing time T41 can be selected as 1 / 5-4 / 5 Tz, preferably 1 / 3-1 / 2 Tz. Tz is the sum of the cold water washing time T31 and the heated washing time T41, and Tz can be selected as 20-35 minutes, preferably 25 minutes.

[0098] Figure 3The second control flow diagram of the present invention is a washing process flow chart after reservation. After the user starts the reservation (S201), the control module obtains the current time T1 of the reservation start (process S202), and then obtains the user's reserved washing end time T2 (process S203). The control module calculates the time difference Td between the two (process S204); then it obtains the washing duration Tc of the user's reserved washing program (process S205), and then performs a spare time judgment on the difference Td and the washing duration Tc (process S206). Specifically, if Td ≥ Tc + Ti (that is, the difference between the washing end time T2 and the current time T1 of the reservation start is greater than or equal to the user's reserved washing program washing time Tc plus the set spare time value Ti), it means that there is spare time in the reservation; otherwise, it means that there is no spare time, and the washing is performed according to the original program parameters (process S207). The spare time value Ti can be selected from 15min to 60min, preferably 30min.

[0099] After determining that there is available time for the appointment, to avoid disturbing the user's rest, washing cannot be done immediately. Parameter adjustments are required (process S208) to enhance the pre-washing treatment of menstrual blood-stained clothing, which will aid in the subsequent tumbling and washing. Specifically: determine the range of available time Tk. The method for determining this range can be the same as for determining available time, and will not be repeated here. Adjust the parameters for each washing stage based on the available time Tk. At the start of washing, first perform a spray-drainage T12 (S209) to ensure thorough rinsing and reduce the residue of uncoagulated menstrual blood, cervical mucus, and endometrial fragments. The spray-drainage T12 can be appropriately increased based on the available time Tk to improve the rinsing effect; see Table 1 for parameter adjustment details. After rinsing, immediately soak the garment in water for time T22 (S2010). During soaking, spray the garment once at interval T5. This spraying process allows for partial water removal, water exchange, and agitation, removing any precipitated serum from the clothing and preventing prolonged soaking that could cause stains dissolved in the water to reappear. The soaking time T22 can be appropriately increased based on available time Tk to enhance the dissolving effect and reduce bloodstain coagulation; see Table 1 for parameter adjustment details. The interval T5 can be selected from 10-60 minutes, preferably 30 minutes. After soaking, drain the water to remove the dirty wastewater. Then, re-fill the garment with water and perform a tumbling wash. In the initial washing stage, perform a cold water wash (S2011) to remove protein-based stains; the cold water is preferably room temperature water. After a certain cold water wash time T32, perform a heated wash for time T42 (S2012) to dissolve fatty stains, better removing these stains and erasing marks. Fatty stains dissolve more easily at 40-50℃, so the heating temperature can be selected as 40-60℃, preferably 45-50℃. The cold water washing time T32 can be selected as 1 / 5-4 / 5Tz, preferably 1 / 2-2 / 3Tz; the heating washing time T42 can be selected as 1 / 5-4 / 5Tz, preferably 1 / 3-1 / 2Tz; the sum Tz of the cold water washing time T32 and the heating washing time T42 can be adjusted appropriately according to the amount of spare time Tk, as detailed in the parameter adjustment table in Table 1. Preferably, as the amount of spare time Tk increases, Tz should be appropriately reduced, because as the amount of spare time Tk increases, the spraying and soaking time increases accordingly, improving the stain removal effect of spraying, rinsing and soaking, which helps with washing. Therefore, reducing Tz can also ensure the washing effect and ensure that the washing ends on time, so as not to affect the user's drying.

[0100] The second aspect of this embodiment discloses a washing method for blood-stained clothing, including a spray washing stage, a soaking washing stage, and a tumbling washing stage performed sequentially (in other words, the clothing treatment equipment performing the above washing method can be preset with a clothing treatment program, which can include the aforementioned stages).

[0101] During the spray washing stage, the spray valve is used to control the spray valve to spray water into the washing tub to rinse the blood-stained clothes, and the drain valve is used to drain the water.

[0102] The soaking stage is used to introduce a preset amount of washing water into the washing tub to soak the blood-stained clothes, and to drain the washing water from the tub at the end of the soaking process.

[0103] The tumbling and washing stage is used to control the washing tub to rotate in both directions alternately to tumble and wash bloodstained clothes.

[0104] Furthermore, the tumbling and washing stage includes:

[0105] The cold water washing stage is used to tumble and wash blood-stained clothing in cold water.

[0106] In the heated washing stage, the washing water is heated to reach the first preset temperature, and the blood-stained clothes are tumbled and washed.

[0107] The cold water condition can be understood as room temperature water that does not require deliberate heating, typically between 15℃ and 25℃. The first preset temperature range is greater than or equal to 40℃ and less than or equal to 60℃. This highly targeted, phased, and temperature-controlled washing method, based on the applicant's research on the characteristics of menstrual blood, effectively improves the washing effect.

[0108] In the early stages of menstruation, menstrual blood contains a certain amount of fibrinolytic enzymes, which can dissolve fibrinogen in the blood, making it easier to liquefy and less prone to clotting. The iron in heme exists in the form of ferrous iron, which is soluble in water and difficult to remove due to cervical mucus soaking, requiring rinsing. In the later stages, after the blood coagulates, the ferrous iron is oxidized to ferric iron, which coagulates with proteins to form blood spots. The separated serum contains proteins, fats, and inorganic substances. Proteins should not be heated, while fats need to be heated to dissolve and be washed away. Therefore, in the early stages, spray rinsing should be used, followed by soaking. In the mechanical washing stage, cold water should be used initially, followed by heated washing in the later stages to achieve a better removal effect of menstrual blood and prevent stains on clothing. This solves the problem of menstrual blood stains on clothing caused by improper washing.

[0109] The third aspect of this embodiment discloses a clothing processing device, which can be a washing machine that uses the washing method provided in any of the preceding embodiments.

[0110] In the different embodiments provided by this invention, the same parameters, terms, logic, etc. should be understood to have the same meaning, and this application does not intentionally repeat the description in each embodiment.

[0111] Exemplary embodiments of this disclosure have been specifically shown and described above. It should be understood that this disclosure is not limited to the detailed structures, arrangements, or implementation methods described herein; rather, this disclosure is intended to cover various modifications and equivalent arrangements contained within the spirit and scope of the appended claims.
