[0042] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0043] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0044] According to an embodiment of the present application, an embodiment of a washing control method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0045] like Figure 1 As shown, the washing control method includes:

[0046] S101, performing hot air dry cleaning pretreatment on the blood-stained washing object pre-coated with detergent.

[0047] When the blood stains on the washing object need to be treated, detergent is first applied to the washing object, and then the washing equipment performs hot air dry cleaning pretreatment on the washing object.

[0048] Specifically, the detergent may be applied manually, or the detergent may be applied to the blood stain by a washing device or other identification device that automatically identifies the location of the blood stain on the washing object.

[0049] The washing objects refer to objects stained with blood, such as clothes, hats, shoes, etc., which are not specifically limited in this embodiment.

[0050] The hot air includes airflow in a first temperature range that matches the detergent, and the first temperature range is higher than room temperature. Specifically, room temperature refers to 25 degrees Celsius. Hot air dry cleaning pretreatment refers to a dry cleaning process with hot air, that is, a waterless process.

[0051] S102, washing the washing object after the hot air dry cleaning pre-treatment.

[0052] After the washing object is subjected to hot air dry cleaning pre-treatment, the active substances in the detergent can be better adsorbed and penetrated on the blood stain. Then, the washing object is subjected to washing treatment. Specifically, washing treatment refers to water treatment, such as high-temperature water washing or high-speed spin rinsing, etc., which is not specifically limited in this embodiment.

[0053] Through the above, before cleaning the bloodstained laundry object, the laundry object is pre-coated with detergent and then subjected to hot air dry cleaning. This allows active substances in the detergent, such as biological enzymes, to better adsorb and penetrate the blood stain, thereby improving the cleaning effect of the blood stain. In addition, the hot air dry cleaning process also saves water resources and avoids resource waste.

[0054] In another embodiment of the present application, a blood-stained object pre-coated with detergent is subjected to hot air dry cleaning pretreatment, comprising:

[0055] S201. Obtain attribute information of detergent.

[0056] Different types of detergents or detergents produced by different manufacturers have different ingredients and manufacturing processes, so the properties of different detergents may vary. In order to better pre-treat the detergent for hot air dry cleaning so that the detergent can better absorb into the washing objects with blood stains, the property information of the detergent is obtained.

[0057] Specifically, the attribute information can be obtained by manual user input or by using an identification device to first identify the detergent and then retrieve the corresponding attribute information from a preset database. For ease of understanding, for example, the identification device is a camera that captures the detergent brand, and then retrieves the attribute information of the detergent associated with the brand from a preset database based on the brand. This embodiment does not specifically limit the process and method for obtaining the attribute information.

[0058] The attribute information refers to information related to the attributes of the detergent, such as the detergent's composition information, dissolution temperature information, viscosity information, acidity and alkalinity, coating area, coating thickness, coating amount, and other information that conventional detergents may have.

[0059] S202: Determine hot air treatment parameters that match the attribute information of the detergent.

[0060] The characteristics or properties of the detergent can be known through the attribute information, such as at what temperature it can better adsorb to the washing object, etc. Therefore, the corresponding hot air treatment parameters can be determined according to the attribute information.

[0061] The hot air treatment parameters refer to parameters of the hot air dry cleaning pre-treatment, which may be some or all parameters of the hot air dry cleaning pre-treatment, and are not limited in this embodiment. Specifically, the hot air treatment parameters include temperature parameters. In addition, the hot air treatment parameters may also include parameters such as time, wind speed, and air volume, which are not specifically limited in this embodiment.

[0062] For ease of understanding, for example, when the attribute information of the detergent indicates that the detergent pre-coated on the washing object can fully absorb and penetrate blood stains at 30 degrees Celsius, the hot air treatment parameters of the hot air dry cleaning pretreatment can be set to a hot air temperature of 30 degrees Celsius.

[0063] S203: providing hot air required for hot air dry cleaning pretreatment according to hot air treatment parameters.

[0064] After the hot air treatment parameters are obtained, the operating parameters of the hot air dry cleaning pretreatment of the washing equipment are adjusted according to the hot air treatment parameters, thereby obtaining hot air that matches the hot air treatment parameters.

[0065] Through the above content, the hot air processing parameters are determined according to the property information of the detergent and hot air is provided according to the determined hot air processing parameters, so that the hot air can change with the change of the detergent, so that for different detergents, the detergent can better adsorb and penetrate the blood stains, thereby improving the cleaning effect of the blood stains.

[0066] In another embodiment of the present application, before performing hot air dry cleaning pretreatment on the blood-stained laundry object pre-coated with detergent, the method further includes:

[0067] S301: When a selection operation for a blood stain cleaning mode is detected, contamination information of the blood stain on the washing object is obtained.

[0068] When a user needs to clean a bloodstained object, a selection operation is triggered. Specifically, the washing machine includes a bloodstain cleaning mode. When the user selects the program corresponding to the bloodstain cleaning mode using the selection button on the washing machine, it is determined that a selection operation for the bloodstain cleaning mode has been detected. The washing machine then displays a reminder message, which is used to remind the user to enter contamination information about the bloodstain on the washing object. In other words, in one application scenario, the washing machine cannot automatically detect the location of the bloodstain on the washing object, nor can it detect the area or thickness of the bloodstain, so manual input is required from the user.

[0069] Among them, the way to display the reminder information can be to display the reminder information on a display screen or to play the reminder information through a loudspeaker. As long as the user is informed that the pollution information needs to be input, the pollution information input by the user can be obtained. This embodiment does not limit the specific method of display.

[0070] The contamination information refers to information related to the blood stain, such as the location, area, thickness, drying time, etc. of the blood stain on the washing object, which is not specifically limited in this embodiment.

[0071] S302: Determine a detergent suitable for the blood stain based on the contamination information.

[0072] Since the contamination information can characterize the relationship between the blood stain and the washing object, such as the location of the blood stain or the length of time the blood stain has been on the washing object, an appropriate detergent can be selected based on the contamination information.

[0073] S303: applying a detergent suitable for the blood stain to the blood-stained portion of the object to be washed.

[0074] After placing the washing object into the treatment drum of the washing device, the user or the detergent dispensing device sprays detergent onto the washing object so that the detergent is applied to the portion of the washing object with the blood stain.

[0075] Through the above content, determining the appropriate detergent according to the contamination information of the blood stain, that is, selecting the appropriate detergent according to the actual contamination of the blood stain, helps to clean the blood stain more efficiently and thoroughly, and improves the cleaning effect of the blood stain.

[0076] In another embodiment of the present application, providing hot air required for hot air dry cleaning pretreatment according to hot air treatment parameters includes:

[0077] S401, start the blower and rotate the treatment drum.

[0078] The washing machine comprises a treatment drum, an air duct connected to the air inlet of the treatment drum, a heating device installed in the air duct, and a blower that provides air supply to the air duct. When the blower is activated, airflow is generated in the air duct. After passing through the heating device, the airflow is heated and enters the treatment drum through the air inlet. There, it comes into contact with the washing objects in the treatment drum, raising the temperature of the washing objects and the detergent, thereby enhancing the adsorption and penetration of the detergent into the blood stain.

[0079] S402 , starting the heating device to make the airflow delivered to the processing cylinder by the air duct meet the first temperature range and be delivered into the processing cylinder through the blower.

[0080] The heating device is started to heat the airflow in the air duct so that the temperature of the airflow is within the first temperature range. Specifically, this embodiment does not specifically limit how to determine the temperature of the airflow, for example, by installing a temperature sensor to detect the temperature of the airflow.

[0081] The first temperature range is obtained based on the hot air treatment parameters, and specifically, the first temperature range may be 35-45 degrees Celsius. The treatment drum contains blood-stained objects pre-coated with detergent.

[0082] Through the above content, the airflow meeting the first temperature range is sent into the processing drum, which facilitates the airflow to heat the washing objects in the processing drum, thereby accelerating the adsorption and penetration effect of the detergent and blood stains.

[0083] In another embodiment of the present application, after the heating device is started so that the airflow delivered to the treatment cylinder by the air duct meets the first temperature range and is delivered into the treatment cylinder by the blower, the method further includes:

[0084] Determine whether the set time range of hot air dry cleaning pretreatment has been reached;

[0085] When the set time range T0 is not reached, the hot air from the blower is kept blowing in and the processing drum is kept rotating for dry cleaning;

[0086] When the set time range T0 is reached, the hot air blowing of the blower is stopped and the rotation of the processing drum is stopped, ending the hot air dry cleaning pretreatment stage.

[0087] In one embodiment, the set duration range can be set based on actual needs. For example, 10 minutes or half an hour is intended to allow the detergent to fully absorb and penetrate the blood stains under the heating of the hot air during the hot air dry cleaning pretreatment phase. The actual absorption and penetration effects are not specifically limited in this embodiment. Simply put, if you want to improve the absorption and penetration effects, you can set the set duration range longer, otherwise, you can set it shorter.

[0088] Through the above content, when the temperature of the air flow blown into the processing drum reaches the requirement, the timing starts, and when the timing time reaches the set time range, the hot air dry cleaning pretreatment stage ends, so as to ensure the treatment effect of the hot air dry cleaning pretreatment stage on the washing object, thereby improving the cleaning effect of blood stains.

[0089] In another embodiment of the present application, a washing process is performed on the washing object after hot air dry cleaning pre-treatment, comprising:

[0090] S601: Determine a washing strategy for washing treatment based on the contamination information and detergent information of a detergent suitable for the bloodstain.

[0091] After the wash object undergoes hot air dry cleaning pre-treatment, it can be washed. Prior to this, different washing strategies are determined based on the different conditions of the wash object. For example, if a blood stain has persisted for a long time (which can be determined based on the contamination information) and the detergent used requires a large amount of water (which can be determined based on the detergent information), a washing strategy involving a longer wash time and a larger amount of water can be determined. This embodiment does not specifically limit the specific washing strategies; for example, a washing strategy includes the type and number of washing stages, as well as the washing parameters corresponding to each washing stage.

[0092] S602: According to the washing strategy, the washing object is processed in at least two washing stages.

[0093] The design water temperature ranges of the washing parameters of different types of washing stages are different, and the design water temperature range of the later washing stage is higher than the design water temperature range of the earlier washing stage.

[0094] Each determined washing strategy includes at least two washing stages. The two washing stages may be the same type of washing treatment, for example, both are rinsing, but the water temperatures of the two washing stages are different.

[0095] Based on the above, different washing strategies are determined based on the different blood stain conditions and detergent usage, ensuring that the washing process can effectively remove the blood stain. Furthermore, the washing strategy includes at least two washing stages with different water temperatures. Using a lower water temperature gradually dissolves the protein in the blood stain as the wash progresses, while using a higher water temperature dissolves the grease in the blood stain, thereby improving the blood stain cleaning effect.

[0096] In another embodiment of the present application, according to the washing strategy, the washing object is subjected to at least two washing stages, including:

[0097] The washing object is washed step by step according to the washing parameters of each washing stage.

[0098] Different washing stages have respective washing parameters, and corresponding washing processes are performed according to the washing parameters.

[0099] The washing water temperature in the washing parameters of each washing stage is different, and the washing water temperature in the later washing stage is higher than the washing water temperature in the earlier washing stage.

[0100] Through the above content, separate washing parameters can be set for each washing stage in the washing strategy, so as to improve the washing effect of each washing stage on the washing object, thereby improving the cleaning effect of blood stains.

[0101] In another embodiment of the present application, according to the washing strategy, the washing object is subjected to at least two washing stages, including:

[0102] S801. For each washing stage in the washing strategy, when controlling the amount of water matched with the washing object to be added to the treatment drum, heated water is input into the treatment drum according to the designed water temperature range of the washing parameters of the washing stage.

[0103] S802: When the real-time temperature of the water in the treatment drum falls within the designed water temperature range, the treatment drum is controlled to rotate according to the washing time and washing speed of the washing parameters.

[0104] Through the above content, when washing the washing object, factors such as water temperature, washing time and washing speed are considered to improve the washing effect.

[0105] In another embodiment of the present application, at least two washing stages include a low-temperature pre-wash stage and a high-temperature main wash stage, the water temperature of the low-temperature pre-wash stage is controlled within a second temperature range, and the water temperature of the high-temperature main wash stage is controlled within a third temperature range, wherein the maximum value of the second temperature range is less than or equal to the minimum value of the third temperature range.

[0106] Among them, the second temperature range is, for example, 30-50 degrees, and the third temperature range is, for example, 55-60 degrees, in order that the water temperature in the latter stage is higher than that in the former stage. The specific temperature range is not specifically limited in this embodiment.

[0107] Through the above content, the two washing stages are set as a low-temperature pre-wash stage and a high-temperature main wash stage, and the water temperature ranges of the two stages are preset, which makes it easier to control the washing conditions of each washing stage, thereby improving the washing effect.

[0108] In another embodiment of the present application, after the high-temperature main wash stage is performed on the washing objects after the hot air dry cleaning pretreatment, the method further includes:

[0109] The washing object is rinsed according to the preset rinsing times and preset rinsing parameters.

[0110] The rinsing speed indicated by the rinsing parameter is greater than the washing speed in the washing stage.

[0111] Through the above content, the rinsing speed is higher, so that the residual blood stains after washing are removed from the washing object under the centrifugal action, solving the problem that the residual blood stains after washing are difficult to remove.

[0112] For ease of understanding, the washing control method in this embodiment is described by taking clothes as the washing object as an example.

[0113] like Figure 2-6 As shown in FIG, the blood-stained clothing is subjected to a process of hot air dry cleaning, room temperature pre-wash, high temperature main wash, and strong rinse. The hot air dry cleaning pre-treatment includes hot air dry cleaning, and the washing treatment includes room temperature pre-wash and high temperature main wash.

[0114] Old blood stains are difficult to clean because the iron in them has oxidized and complexed with proteins to coagulate on the surface of the matrix. They often require the full action of biological enzymes in detergents, such as proteases to break down hemoglobin and lipases to break down the fat components in blood stains. The effect of detergents on clothing is a comprehensive and complex process, mainly involving adsorption, wetting, penetration, solubilization, and emulsification. In addition, most enzymes in detergents are most active at 40°C, so the main purpose of hot air dry cleaning is to pre-mix and act on the blood stains with the detergent, so that the surfactant molecules in the detergent (such as biological enzymes, etc.) can be fully adsorbed, penetrated, and decomposed on the surface of the blood stains, so that the blood stains can be more easily removed under the mechanical force of subsequent normal temperature washing and high temperature washing processes.

[0115] like Figure 3 As shown, the process of hot air dry cleaning is as follows:

[0116] →Start the fan and the inner drum to dry clean the bloodstained clothes;

[0117] → Air duct heating pipe heating;

[0118] →The temperature sensor determines whether the air duct temperature has risen to 40℃. When the temperature rises to 40℃, the air duct heating is stopped. The temperature sensor then determines whether the air duct temperature has dropped to 35℃. When the temperature drops to 35℃, the fan is started to increase the air duct temperature. This cyclic judgment method is used to control the inlet air temperature to maintain around 40℃ (35℃-40℃). At the same time, the inlet air temperature should not be too high. When the temperature is too high, the hemoglobin in the blood stains will easily coagulate and become difficult to remove. Therefore, the temperature of the hot air is controlled at 35℃-40℃. The number of revolutions of the inner drum during dry cleaning is the same as that during normal washing, which is 50rpm.

[0119] → Determine whether the hot air dry cleaning set time T0 has been reached. If the hot air dry cleaning set time T0 has not been reached, continue blowing hot air and rotating the inner drum for dry cleaning. When the hot air dry cleaning set time T0 is reached, stop the air inlet and the inner drum from rotating, ending the hot air dry cleaning phase. The hot air dry cleaning set time is 5-10 minutes.

[0120] Blood stains contain two main components: hemoglobin and grease. Hemoglobin, the main component of hemoglobin, gives blood stains their red color and is the primary reason they are difficult to clean. The washing efficiency of hemoglobin is most affected by water temperature. As the temperature rises, the protein tends to coagulate and become difficult to remove with the wash water. However, when washing at room temperature (30°C), protein is more water-soluble and gradually dissolves into the wash water, effectively removing it from clothing. Grease, on the other hand, becomes more water-soluble as temperature rises. At room temperature (30°C), it is less water-soluble, making it difficult to wash, while at 60°C, it achieves better washing results. Therefore, to address the different characteristics of these two main components in blood stains, we divide the washing process into two parts: a pre-wash at room temperature (30°C) and a main wash at high temperature (60°C), allowing the two main components of blood stains to be removed separately in two separate wash stages.

[0121] like Figure 4 As shown, the process of normal temperature pre-wash is as follows:

[0122] →Weigh the clothes;

[0123] →Choose the appropriate water intake according to the weight of the clothes;

[0124] →The temperature sensor determines whether the normal temperature water has reached 30℃. If the water temperature is ≥30℃, pre-wash will start directly. If the water temperature is <30℃, the water temperature will be heated to 30℃ and maintained before pre-washing.

[0125] → Check whether the pre-wash time T1 has been reached. When this time is reached, drain the water, ending the pre-wash. Because wash time has little effect on blood stain removal, a pre-wash time T1 of 10-15 minutes is sufficient, and the timer should not begin until the water temperature reaches 30°C. Draining the water after the pre-wash ensures that the blood pigment is removed with the wash water to prevent it from re-solidifying and forming a stain in subsequent washes.

[0126] like Figure 5 As shown, the process of high-temperature main wash is as follows:

[0127] → The same amount of water is used for the pre-wash;

[0128] → Heat the water temperature to 60℃ and maintain the water temperature for the main wash to wash away the grease in the blood stains;

[0129] → Check whether the main wash setting time T2 has been reached. When the main wash setting time T2 is reached, drain the water and end the main wash. The main wash setting time T2 is 10min-15min, and the timing will not start until the water temperature rises to 60℃.

[0130] like Figure 6 As shown in the figure, after the main wash phase, it enters the strong rinse phase. Strong rinse is performed twice, and the speed is 60rpm-120rpm. Compared with the conventional rinse speed of 50rpm, it can better separate the residual blood stains from the clothes, further improving the effect of blood stain cleaning. The strong rinse process is as follows:

[0131] → Let water in and start the first rinse;

[0132] → Rinse the clothes at a strong speed;

[0133] → Determine whether the rinse setting time T3 has been reached. If so, drain the water and re-enter the same amount of water as the first rinse;

[0134] → Rinse the clothes for the second time at a strong speed;

[0135] → Determine whether the rinse setting time T3 has been reached. If so, drain the water and end the strong rinse stage;

[0136] →Finally, the dehydration is completed and the blood stain cleaning mode ends.

[0137] The present application also provides a washing device, comprising a treatment drum, an air duct connected to an air inlet of the treatment drum, a heating device disposed on the air duct, a blower for providing air supply power to the air duct, and a controller;

[0138] The controller is electrically connected to the blower and the processing drum, and is used to perform hot air dry cleaning pretreatment on the blood-stained washing object with a preset detergent based on the blower, the heating device and the processing drum; the detergent is preset at the blood stain of the washing object, and the hot air includes an airflow in a first temperature range that matches the detergent, and the first temperature range is higher than normal temperature; and based on the processing drum, the washing object after the hot air dry cleaning pretreatment is washed.

[0139] Through the above content, by pre-applying detergent on the blood stain area and drying the clothes with hot air, the active substances (biological enzymes, etc.) in the detergent can be better adsorbed and penetrated on the blood stain, solving the problem of poor effect of detergent on blood stains and the huge water consumption of the spray washing plus soaking washing solution.
