Description

Technical Field

[0001] The present application relates to the field of equipment control, and in particular, to an odor removal method and a control method of a clothing processing device, and a clothing processing device. Background Art

[0002] As people's living standards improve, their requirements for clothing processing are getting higher and higher. Users usually choose clothing processing equipment such as washing and drying machines and clothes dryers with multiple functions. For example, in addition to the common washing and drying functions, they also need to have functions such as sterilization, disinfection, and deodorization.

[0003] Current clothing treatment equipment uses soluble fragrance-retaining products to add fragrance to clothing when removing odors from clothing, but this odor removal method is costly. Summary of the invention

[0004] The embodiments of the present application provide a method for removing odors from a clothing treatment device, a control method, and a clothing treatment device, so as to at least solve the technical problem of high odor removal costs.

[0005] According to a first aspect of an embodiment of the present application, a method for removing odor from a clothing processing device is provided, which is applied to the clothing processing device, wherein the clothing processing device comprises a processing drum and an air duct, wherein a fan is provided in the air duct, and wherein the fan is used to controllably introduce fresh air into the air duct, and the method comprises:

[0006] Acquiring musty odor data, wherein the musty odor data includes data obtained by detecting musty odor in the treatment cylinder and / or in the air duct;

[0007] According to the musty odor intensity represented by the musty odor data, the fan is selectively controlled to introduce fresh air into the air duct or the rotation speed of the fan is adjusted.

[0008] In this embodiment, the fan set in the air duct is used to control the fan to introduce fresh air or adjust the fan speed when deodorization is required based on the obtained musty odor data. By introducing fresh air, the fresh air is mixed with the original circulating airflow in the air duct, replacing the original circulating airflow with odor, thereby achieving deodorization. This deodorization method does not require the consumption of fragrance products, thereby reducing the deodorization cost.

[0009] In combination with the first aspect, in an optional implementation of the embodiment of the present application,

[0010] The selectively controlling the fan to introduce fresh air into the air duct or adjusting the speed of the fan according to the musty odor magnitude represented by the musty odor data includes:

[0011] Determining a musty odor grade according to the musty odor data, wherein different musty odor grades represent different musty odor levels;

[0012] If the musty odor level exceeds a preset first level, controlling the fan to introduce fresh air into the air duct;

[0013] If the musty odor level is lower than a preset second level, reducing the speed of the fan;

[0014] Wherein, the second level is less than or equal to the first level.

[0015] This implementation method can be used to identify the severity of the musty odor by setting the musty odor level, which is convenient and quick, and helps to reduce the amount of calculation required to determine the severity of the musty odor, thereby reducing the calculation cost of the deodorization process. At the same time, when the musty odor level exceeds the first level, the introduction of fresh air is controlled, and when it is lower than the second level, the speed of the fan is reduced, which helps to reduce the noise and power consumption of the fan, thereby reducing the cost of deodorization.

[0016] In combination with the first aspect, in an optional implementation of the embodiment of the present application, if the musty odor level is lower than a preset second level, reducing the speed of the fan includes:

[0017] Every time the musty odor level decreases by a preset target level, the speed of the fan is reduced by a preset target speed based on the current speed;

[0018] Alternatively, the more the musty odor level decreases within a preset time period, the more the rotation speed of the fan is reduced.

[0019] By adopting this implementation, when reducing the speed of the fan, the fixed speed value can be reduced each time, that is, the target speed is reduced each time, which is conducive to reducing the amount of calculation, thereby reducing the deodorization cost. The degree of reduction of the fan speed can also be determined according to the magnitude of the change in the musty odor level, so that when the change in the musty odor level is relatively small, the fan speed is slightly reduced, thereby ensuring the deodorization efficiency while reducing power consumption and noise.

[0020] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the musty odor data is periodically acquired, and each musty odor data corresponds to a musty odor level;

[0021] The more the musty odor level is reduced, the more the speed of the fan is reduced, including:

[0022] Subtracting the reference musty odor level from the latest musty odor level to obtain a level reduction value, wherein the reference musty odor level is the musty odor level corresponding to the first musty odor data obtained or the maximum value of the musty odor levels corresponding to all musty odor data, and the latest musty odor level is the musty odor level corresponding to the latest musty odor data obtained;

[0023] According to the threshold interval in which the level reduction value is located, the speed reduction value is calculated using the correction coefficient corresponding to the threshold interval and the level reduction value, wherein the larger the threshold interval is, the larger the corresponding correction coefficient is;

[0024] The speed reduction amplitude of the fan is corrected to the speed reduction value.

[0025] With this implementation method, the level reduction value, that is, the change in the musty odor level, is used to determine the correction coefficient, and then the speed reduction value is obtained in combination with the level reduction value, so that the speed of the fan can change with the change in the musty odor level, thereby ensuring that when the musty odor level decreases faster, the speed of the fan decreases more, and when the musty odor level decreases slower, the speed of the fan decreases less, thereby ensuring the deodorization efficiency while maximizing electricity savings and reducing noise.

[0026] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the calculating the speed reduction value according to the threshold interval in which the level reduction value is located, using the correction coefficient corresponding to the threshold interval and the level reduction value, includes:

[0027] If the level reduction value is within a preset first threshold interval, multiplying the level reduction value by a preset first coefficient to obtain a speed reduction value;

[0028] If the level reduction value is within a preset second threshold interval, multiplying the level reduction value by a preset second coefficient to obtain a speed reduction value;

[0029] If the level reduction value is within a preset third threshold interval, the level reduction value is multiplied by a preset third coefficient to obtain a speed reduction value;

[0030] Among them, the lower limit value of the first threshold interval is greater than or equal to the upper limit value of the second threshold interval, the lower limit value of the second threshold interval is greater than or equal to the upper limit value of the third threshold interval, the first coefficient is greater than the second coefficient, and the second coefficient is greater than the third coefficient.

[0031] By adopting this implementation method, different threshold intervals can correspond to different coefficients, which is beneficial to reduce the amount of calculation in the deodorization process, reduce the occupation of computing resources, and reduce computing costs.

[0032] In combination with the first aspect, in an optional implementation manner of the embodiment of the present application, the method further includes:

[0033] According to the musty odor level corresponding to the first musty odor data obtained, the rotation speed of the fan is adjusted to a preset rotation speed, wherein different musty odor levels are pre-associated with different preset rotation speeds.

[0034] With this implementation, after obtaining the first musty odor level, the fan is controlled to introduce fresh air while controlling the fan speed, which is conducive to the fan using a more suitable speed to quickly remove odors and reduce power consumption and noise.

[0035] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the air duct is connected to an exhaust port, the exhaust port can be controlled to be opened and closed, and the exhaust port is connected to the external environment of the clothes processing device;

[0036] The method further comprises:

[0037] When the fan is controlled to introduce fresh air into the air duct, the exhaust port is controlled to open.

[0038] By adopting this implementation method, the exhaust port can easily balance the air pressure in the air duct and the processing tube, and at the same time it is beneficial to discharge the airflow with odor, thereby improving the deodorization efficiency.

[0039] In combination with the first aspect, in an optional implementation of the embodiment of the present application, after controlling the fan to introduce fresh air into the air duct, the method further includes:

[0040] Acquire environmental parameters of the external environment of the clothing processing device;

[0041] adjusting the volume of fresh air introduced into the air duct by the fan according to the environmental parameter so that the environmental parameter is within a preset environmental parameter range;

[0042] Wherein, the environmental parameter includes at least one of environmental temperature and environmental humidity.

[0043] By adopting this implementation method, it is possible to balance the environmental parameters of the external environment while removing odors, which is beneficial to improving the user experience of the clothing processing equipment.

[0044] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the fan includes a double-suction fan, and the double-suction fan is used to controllably introduce fresh air into the air duct and to agitate the air in the air duct to form a circulating airflow flowing between the processing cylinder and the air duct;

[0045] Alternatively, the fan includes a fresh air fan and an internal fan, wherein the fresh air fan is used to controllably introduce fresh air into the air duct, and the internal fan is used to agitate the air in the air duct to form a circulating airflow flowing between the processing cylinder and the air duct.

[0046] By adopting this implementation method, when the fan is a double-suction fan, reducing the fan speed can simultaneously reduce the amount of fresh air introduced and reduce the flow rate of the circulating airflow, thereby reducing the noise and power consumption while reducing the gas entering the room from the clothing processing equipment, thereby reducing the impact on the indoor environment.

[0047] According to a second aspect of an embodiment of the present application, a control method for a clothing processing device is provided, including the odor removal method described above.

The double-suction fan is used to agitate the air in the air duct to form a circulating airflow flowing between the processing drum and the air duct, and the double-suction fan is also used to controllably introduce fresh air into the air duct.

[0050] By adopting this implementation method, the double-suction fan can not only stimulate the air flow in the air duct, but also introduce fresh air into the air duct. When removing odors, the characteristics of the double-suction fan can be used to use the fresh air from the external environment to replace the circulating airflow with odor, thereby achieving low-cost odor removal.

[0052] The vent can be controlled to open and close;

[0053] When the driving motor drives the impeller to rotate, air from the external environment can be introduced into the cavity of the volute through the air vent and mixed with the airflow entering the cavity through the volute air inlet, and the mixed airflow is discharged from the volute air outlet.

[0054] In combination with the third aspect, in an optional implementation of the embodiment of the present application, the impeller is rotatably disposed in the volute; the impeller includes a first blade structure and a second blade structure, the first blade structure and the second blade structure are connected side by side along the axial direction of the impeller and are synchronously driven by the drive motor; wherein the first blade structure is arranged close to the air vent for introducing air from the external environment into the double-suction fan, and the second blade structure is arranged close to the volute air inlet for introducing the airflow inside the air duct into the double-suction fan.

[0069] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0070] It should be understood that the "plurality" mentioned in this article refers to two or more. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in order to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first", "second" and so on are used to distinguish between the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first", "second" and so on do not limit the quantity and execution order, and the words "first", "second" and so on do not limit certain different

[0071] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.

[0072] As people's living standards improve, people have higher and higher requirements on the functions of washing equipment. People hope that washing and drying machines not only have the function of drying but also have other functions, such as sterilization, disinfection, wrinkle removal and keeping the fragrance on the dried clothes.

[0073] People often use methods such as adding soluble fragrance-retaining products into the drum to keep the fragrance on clothes, but this method has poor effect and high consumption, which is very wasteful and increases the cost of deodorization.

[0074] Based on this, the embodiments of the present application provide a deodorization method, a control method and a clothing processing device for a clothing processing device. The technical solution is combined with a double-suction fan structure. Under the attraction of the double-blade mechanism centrifuge, the fresh air is combined with the internal circulating air. At the same time, an odor sensor is added in the barrel. When the odor sensor recognizes the smell of mold, the fresh air is turned on, otherwise the fresh air is turned off for internal circulation. In this way, the fresh air ventilation function of the clothes is realized, and energy and electricity are saved.

[0075] The embodiments of the present application solve at least one of the following technical problems:

[0076] 1. Reduce the fan load and increase the evaporation rate of moisture in clothes.

[0077] 2. Realize the exchange of fresh air and internal circulation air to remove odor from clothes.

[0078] 3. Odor sensors identify musty odors and reduce the need for additional aromatherapy devices.

[0079] The embodiments of the present application have at least the following beneficial effects:

[0080] The double-suction blade fan clothing processing device designed in the present technical solution adds an odor sensor in the barrel. When the odor sensor identifies the smell of mold, the fresh air is turned on, otherwise the fresh air is turned off for internal circulation, thereby realizing the fresh air ventilation function for clothes and saving energy and electricity.

[0081] This technical solution can not only improve the heat transfer exchange effect between hot and humid air and fresh air, but also achieve the following effects:

[0082] 1. The existing fan system is changed to a double-blade fan, combined with an odor sensor. When a musty smell is detected, fresh air is introduced from the outer box of the air duct system. This can ensure that the circulating air volume remains unchanged, accelerate the circulation efficiency, and purify the odor of clothes and the barrel;

[0083] 2. This fan structure can reduce the inlet air temperature and the temperature inside the barrel during the drying stage, reduce the start and stop of the electric heater 9 and the water consumption of condensed water, and save energy and electricity.

[0084] The embodiments of the present application have at least the following features:

[0085] The double-blade fan clothing treatment device designed in this technical solution uses a volute structure with an opening to fully utilize the fan to introduce fresh air from the outer box. An odor sensor is added to the barrel. When the odor sensor identifies the smell of mold, the fresh air is turned on, otherwise the fresh air is turned off for internal circulation, so that the fresh air ventilation function of the clothes is realized in this way, and energy and electricity are saved.

[0086] Next, the deodorization method of the clothing processing device provided in the embodiment of the present application is further described. The deodorization method of the clothing processing device provided in the embodiment of the present application is applied to the clothing processing device, the clothing processing device includes a processing drum and an air duct, the air duct is provided with a fan, and the fan is used to introduce fresh air into the air duct in a controllable manner. Figure 1 The flowchart of the deodorization method of the clothing treatment equipment is shown, and the method includes the following processing process.

[0087] S100: Obtain musty smell data.

[0088] The musty odor data includes data obtained by detecting musty odors in the treatment cylinder and / or in the air duct.

[0089] In one embodiment, the processing drum is also referred to as a drum, a barrel, an inner drum, etc. Whether it is necessary to deodorize the clothes can be determined according to the user's settings, or it can be determined by the clothes processing device according to the program it runs. Specifically, the user can control the clothes processing device to run the deodorization program by himself, and at this time it is determined that the clothes in the processing drum need to be deodorized. Furthermore, the operating program of the clothes processing device may include deodorization before or after running at least one of the processing programs of washing, dehydration, drying and care. Therefore, this embodiment does not specifically limit the means of determining whether deodorization is needed.

[0090] In one embodiment, the musty odor data is collected by a sensor capable of detecting musty odor. Specifically, the sensor can be installed in the treatment tube, or on the outer peripheral side of the treatment tube, as long as it does not affect the air intake of the treatment tube. The sensor can be an odor sensor. Preferably, the odor sensor is mainly composed of an electronic nose system, which can identify a variety of odors, including musty odor. Further preferably, in order to reduce costs, only a musty odor detection sensor is used.

[0091] When the circulating airflow circulates between the air duct and the processing drum, the musty smell carried in the circulating airflow will be detected by the sensor, thereby generating musty smell data. Among them, the musty smell data generated will be different depending on the size of the musty smell. In other words, the severity of the musty smell in the clothing processing device can be known through the musty smell data.

[0092] S102. According to the musty odor intensity represented by the musty odor data, selectively control the fan to introduce fresh air into the air duct or adjust the rotation speed of the fan.

[0093] The musty smell data can characterize the magnitude of the musty smell, thereby knowing the magnitude of the musty smell. For ease of understanding, the magnitude of the musty smell can be specifically distinguished by setting a threshold. For example, when the musty smell data exceeds a certain threshold, it characterizes that the musty smell is large, otherwise it characterizes that the musty smell is small, thereby determining the magnitude of the musty smell characterized by the musty smell data.

[0094] Therefore, after the musty odor data is obtained, the fan can be selectively controlled to introduce fresh air or adjust the speed of the fan according to the musty odor data.

[0095] It should be noted that before deodorization, if the fan is in a state of introducing fresh air, the fan is controlled not to introduce fresh air into the air duct, and then the detection and acquisition of musty odor data is started, so as to improve the accuracy of musty odor data. It should also be noted that when deodorization is required, the internal fan in the air duct for agitating the air flow in the air duct needs to be started, so that the internal fan agitates the air flow between the air duct and the treatment cylinder to circulate.

[0096] In this embodiment, the fan set in the air duct is used to control the fan to introduce fresh air or adjust the fan speed when deodorization is required based on the obtained musty odor data. By introducing fresh air, the fresh air is mixed with the original circulating airflow in the air duct, replacing the original circulating airflow with odor, thereby achieving deodorization. This deodorization method does not require the consumption of fragrance products, thereby reducing the deodorization cost.

[0097] In a possible embodiment of the present application, Figure 2 As shown,

[0098] The selectively controlling the fan to introduce fresh air into the air duct or adjusting the speed of the fan according to the musty odor magnitude represented by the musty odor data includes:

[0099] S200: Determine a musty odor level according to the musty odor data.

[0100] Among them, different musty odor levels represent different musty odor levels; specifically, a higher musty odor level represents a greater musty odor level, and a lower musty odor level represents a smaller musty odor level. When the musty odor level is 0, it represents no musty odor.

[0101] S202: If the musty odor level exceeds a preset first level, control the fan to introduce fresh air into the air duct.

[0102] In one embodiment, the first level can be set according to actual needs, so this embodiment does not limit the specific value of the first level. For ease of understanding, for example, there are 5 musty odor levels preset, from low to high, 1, 2, 3, 4 and 5. The user sets the first level to 3, and when the musty odor level exceeds 3, the fan is controlled to introduce fresh air into the air duct.

[0103] In addition, it should be noted that when determining the musty odor level based on the musty odor data, the musty odor data can be sampled in advance and then graded so that each musty odor level corresponds to a certain range of musty odor data. For example, musty odor data within 0-10 is determined as level 1, musty odor data within 10-20 is determined as level 2, and so on.

[0104] Since the fan can simultaneously complete the introduction of fresh air and the agitation of the circulating airflow, the introduction of fresh air referred to in this embodiment refers to the introduction of fresh air without stopping the fan to agitate the circulating airflow.

[0105] S204: If the musty odor level is lower than a preset second level, reducing the rotation speed of the fan.

[0106] The second level is set in the same way as the first level, and can be set according to actual needs. The second level is less than or equal to the first level. For example, both the first level and the second level can be level 3, or the first level can be level 3 and the second level can be level 1. This embodiment does not specifically limit this.

[0107] It should be noted that if the second level is lower than the first level, then when the musty odor level is between the first level and the second level, no control action may be performed, and the musty odor level may be waited to increase or decrease.

[0108] By adopting this implementation method, the musty odor level is set to identify the musty odor level, which is convenient and quick, and helps to reduce the amount of calculations for determining the musty odor level, thereby reducing the calculation cost of the deodorization process. At the same time, when the musty odor level exceeds the first level, the introduction of fresh air is controlled, and when it is lower than the second level, the fan speed is reduced, which helps to reduce the fan noise and power consumption, thereby reducing the cost of deodorization. In addition, when the fan uses a double-suction fan, reducing the fan speed can simultaneously reduce the amount of fresh air introduced and reduce the flow rate of the circulating airflow, which can reduce the noise and power consumption while reducing the gas entering the room from the clothing processing equipment, thereby reducing the impact on the indoor environment.

[0109] Optionally, in an implementation of this embodiment, if the musty odor level is lower than a preset second level, reducing the rotation speed of the fan includes:

[0110] Every time the musty odor level decreases by a preset target level, the speed of the fan is reduced by a preset target speed based on the current speed;

[0111] Or, the more the musty odor level decreases within a preset time period, the more the rotation speed of the fan is reduced;

[0112] Alternatively, the faster the rate at which the musty odor level decreases, the more the speed of the fan is reduced.

[0113] In one embodiment, the target level number can be 1 or other values. Taking the target level number as 1 as an example, the target speed is further reduced based on the current speed every time the musty odor level decreases by 1 level. Specifically, for example, the musty odor level detected at the beginning is level 3, and the fan speed at that time is 200. As the deodorization proceeds, the musty odor level detected for the second time is level 2, which is reduced by 50 based on 200, and the musty odor level detected for the third time is level 1, which is reduced by 50 based on 200-50.

[0114] In another embodiment, the speed of the fan is reduced each time, which is determined according to the degree of reduction of the musty odor level. For example, if the initial musty odor level is level 5, and the second detection is level 4, the degree of reduction is 1, then the speed can be reduced by 10. If the third detection is level 2, the degree of reduction is 4-2=2, then the speed can be reduced by 20.

[0115] In one embodiment, in addition to monitoring the change value of the musty odor level, the change rate of the musty odor level can also be monitored. Specifically, the rate at which the musty odor level decreases can be obtained by comparing the change amount of the musty odor level with the time length. After obtaining the rate at which the musty odor level decreases, the speed can be adjusted using a preset speed threshold, for example, if the speed threshold is exceeded, the speed is reduced by 50 rpm, and if the speed threshold is not exceeded, the speed is reduced by 20 rpm, so as to remove the odor faster.

[0116] By adopting this implementation, when reducing the speed of the fan, the fixed speed value can be reduced each time, that is, the target speed is reduced each time, which is conducive to reducing the amount of calculation, thereby reducing the deodorization cost. The degree of reduction of the fan speed can also be determined according to the magnitude of the change in the musty odor level, so that when the change in the musty odor level is relatively small, the fan speed is slightly reduced, thereby ensuring the deodorization efficiency while reducing power consumption and noise.

[0117] Optionally, in an implementation of this embodiment, the musty odor data is periodically acquired, and each musty odor data corresponds to a musty odor level;

[0118] The more the musty odor level is reduced, the more the speed of the fan is reduced, including:

[0119] Subtracting the reference musty odor level from the latest musty odor level to obtain a level reduction value, wherein the reference musty odor level is the musty odor level corresponding to the first musty odor data obtained or the maximum value of the musty odor levels corresponding to all musty odor data, and the latest musty odor level is the musty odor level corresponding to the latest musty odor data obtained;

[0120] According to the threshold interval in which the level reduction value is located, the speed reduction value is calculated using the correction coefficient corresponding to the threshold interval and the level reduction value, wherein the larger the threshold interval is, the larger the corresponding correction coefficient is;

[0121] The speed reduction amplitude of the fan is corrected to the speed reduction value.

[0122] For ease of understanding, for example, when the fan's dual speed is reduced for the first time, it is reduced by 50, and then the musty odor data is obtained and a new musty odor level is determined. It is found that the difference between the newly determined musty odor level and the reference musty odor level has increased, so a larger correction coefficient is used to multiply the level reduction value, thereby obtaining a larger speed reduction value of 80. At this time, the fan is reduced from 50 to 80. It should be noted that when correcting the speed reduction value, the speed reduction value is subtracted from the fan's initial speed.

[0123] The size of the threshold interval is determined by comparing the upper limit and the lower limit of the threshold interval. For example, if the lower limit of a threshold interval exceeds the upper limit of another threshold interval, the threshold interval is considered to be larger than the other threshold interval.

[0124] With this implementation method, the level reduction value, that is, the change in the musty odor level, is used to determine the correction coefficient, and then the speed reduction value is obtained in combination with the level reduction value, so that the speed of the fan can change with the change in the musty odor level, thereby ensuring that when the musty odor level decreases faster, the speed of the fan decreases more, and when the musty odor level decreases slower, the speed of the fan decreases less, thereby ensuring the deodorization efficiency while maximizing electricity savings and reducing noise.

[0125] Optionally, in an implementation of this embodiment, the calculating the speed reduction value according to the threshold interval in which the level reduction value is located and using the correction coefficient corresponding to the threshold interval and the level reduction value includes:

[0126] If the level reduction value is within a preset first threshold interval, multiplying the level reduction value by a preset first coefficient to obtain a speed reduction value;

[0127] If the level reduction value is within a preset second threshold interval, multiplying the level reduction value by a preset second coefficient to obtain a speed reduction value;

[0128] If the level reduction value is within a preset third threshold interval, the level reduction value is multiplied by a preset third coefficient to obtain a speed reduction value;

[0129] Among them, the lower limit value of the first threshold interval is greater than or equal to the upper limit value of the second threshold interval, the lower limit value of the second threshold interval is greater than or equal to the upper limit value of the third threshold interval, the first coefficient is greater than the second coefficient, and the second coefficient is greater than the third coefficient.

[0130] In one embodiment, the first threshold interval is greater than 3, the second threshold interval is 1 to 3, the third threshold interval is less than 1, the first coefficient is 250, the second coefficient is 200, and the third coefficient is 150.

[0131] By adopting this implementation method, different threshold intervals can correspond to different coefficients, which is beneficial to reduce the amount of calculation in the deodorization process, reduce the occupation of computing resources, and reduce computing costs.

[0132] Optionally, in an implementation of this embodiment, the method further includes:

[0133] According to the musty odor level corresponding to the first musty odor data obtained, the rotation speed of the fan is adjusted to a preset rotation speed, wherein different musty odor levels are pre-associated with different preset rotation speeds.

[0134] Specifically, the greater the musty odor level, the greater the associated preset speed.

[0135] With this implementation, after obtaining the first musty odor level, the fan is controlled to introduce fresh air while controlling the fan speed, which is conducive to the fan using a more suitable speed to quickly remove odors and reduce power consumption and noise.

[0136] Optionally, in an implementation of this embodiment, the air duct is connected to an exhaust port 13, the exhaust port 13 can be controlled to be opened and closed, and the exhaust port 13 is connected to the external environment of the clothes processing device;

[0137] The method further comprises:

[0138] When the fan is controlled to introduce fresh air into the air duct, the exhaust port 13 is controlled to open.

[0139] By adopting this implementation, the exhaust port 13 can easily balance the air pressure in the air duct and the processing tube, and at the same time it is beneficial to discharge the airflow with odor, thereby improving the deodorization efficiency.

[0140] Optionally, in an implementation of this embodiment, after controlling the fan to introduce fresh air into the air duct, the method further includes:

[0141] Acquire environmental parameters of the external environment of the clothing processing device;

[0142] adjusting the volume of fresh air introduced into the air duct by the fan according to the environmental parameter so that the environmental parameter is within a preset environmental parameter range;

[0143] Wherein, the environmental parameter includes at least one of environmental temperature and environmental humidity.

[0144] It should be noted that the purpose of detecting environmental parameters is mainly to adjust the environmental parameters to within the environmental parameter range to improve the user experience in the room. Specifically, the temperature and humidity of the circulating airflow are high, and the temperature and humidity of the external environment are low. Therefore, when the environmental parameters need to be increased, the amount of fresh air introduced can be increased so that more circulating airflow is replaced into the external environment. When the environmental parameters need to be reduced, the amount of fresh air introduced can be reduced so that less circulating airflow is replaced into the external environment.

[0145] By adopting this implementation method, it is possible to balance the environmental parameters of the external environment while removing odors, which is beneficial to improving the user experience of the clothing processing equipment.

[0146] Optionally, in an implementation of this embodiment, the fan includes a double-suction fan, which is used to controllably introduce fresh air into the air duct and to agitate the air in the air duct to form a circulating airflow flowing between the processing cylinder and the air duct;

[0147] Alternatively, the fan includes a fresh air fan and an internal fan, wherein the fresh air fan is used to controllably introduce fresh air into the air duct, and the internal fan is used to agitate the air in the air duct to form a circulating airflow flowing between the processing cylinder and the air duct.

[0148] A control method for a clothing processing device provided in an embodiment of the present application includes the odor removal method described above.

[0149] A clothing processing device provided in an embodiment of the present application adopts the above-mentioned odor removal method or the above-mentioned control method.

[0150] Optionally, in one implementation of this embodiment, the clothing processing device includes a processing drum and an air duct, and a double-suction fan is provided in the air duct. The double-suction fan is used to agitate the air in the air duct to form a circulating airflow flowing between the processing drum and the air duct, and the double-suction fan is also used to controllably introduce fresh air into the air duct.

[0151] By adopting this implementation method, the double-suction fan can not only stimulate the air flow in the air duct, but also introduce fresh air into the air duct. When removing odors, the characteristics of the double-suction fan can be used to use the fresh air from the external environment to replace the circulating airflow with odor, thereby achieving low-cost odor removal.

[0152] In an optional implementation of the embodiment of the present application, as Figure 3-6As shown, the double-suction fan includes a volute, an impeller 3 and a driving motor for driving the impeller 3 to rotate, the volute is provided with a volute air inlet, a volute air outlet and an air vent, wherein the volute air inlet is used for allowing the airflow inside the air duct 8 to enter, the volute air outlet is used for allowing the fluid in the double-suction fan 1 to flow into the air duct 8, and the air vent is communicated with the external environment of the clothing processing device, and is used for introducing fresh air into the air duct 8;

[0153] The vent can be controlled to open and close;

[0154] When the driving motor drives the impeller 3 to rotate, the air from the external environment can be introduced into the cavity of the volute through the air vent and mixed with the airflow entering the cavity through the volute air inlet, and the mixed airflow is discharged from the volute air outlet.

[0155] In one embodiment, the impeller 3 is rotatably connected to the volute via a bearing, that is, the impeller 3 and the volute can move relative to each other, the impeller 3 rotates, but the volute does not rotate. In another embodiment, the impeller 3 is not connected to the volute, but is only located inside the volute, and the impeller 3 rotates inside the volute by connecting to a driving mechanism. This embodiment does not specifically limit whether the impeller 3 is connected to the volute and how it is connected, and it is intended that the impeller 3 is located inside the volute.

[0156] The driving mechanism is arranged in the driving mechanism cover 2 .

[0157] In an optional implementation of the embodiment of the present application, the impeller 3 is rotatably arranged in the volute; the impeller 3 includes a first blade structure 31 and a second blade structure 32, and the first blade structure 31 and the second blade structure 32 are connected side by side along the axial direction of the impeller 3 and are synchronously driven by the drive motor; wherein the first blade structure 31 is arranged close to the air vent for introducing air from the external environment into the double-suction fan 1, and the second blade structure 32 is arranged close to the volute air inlet for introducing the airflow inside the air duct 8 into the double-suction fan 1.

[0158] In an optional implementation of the embodiment of the present application, the impeller 3 is provided with an annular fan blade partition 4, and the first fan blade structure 31 and the second fan blade structure 32 are fixed on both sides of the fan blade partition 4; the first fan blade structure 31 includes a plurality of first blades; the second fan blade structure 32 includes a plurality of second blades; the plurality of first blades are arranged in a ring shape and are fixedly connected to the first surface of the fan blade partition 4 at equal intervals; the plurality of second blades are arranged in a ring shape and are fixedly connected to the second surface of the fan blade partition 4 at equal intervals; the ring formed by the plurality of first blades is coaxial with the ring formed by the plurality of second blades; the length of the first blade is less than the length of the second blade.

[0159] In one embodiment, after the first fan blade structure 31 and the second fan blade structure 32 rotate, they guide the air, form airflow and encourage the airflow to move in a fixed direction. Since a vent is provided on the wall of the volute relative to the first fan blade structure 31, when the first fan blade structure 31 rotates, the air outside the vent is introduced into the volute to form fresh air.

[0160] In one embodiment, the first fan blade structure 31 and the second fan blade structure 32 are both fixedly connected to the fan blade partition 4. In one embodiment, the fixed connection is achieved by welding; in other embodiments, the fixed connection is achieved by gluing or interference fit, etc., which is not specifically limited in this embodiment.

[0161] In one embodiment, the number of the first blades may be the same as the number of the second blades, or may be different from the number of the second blades, and this embodiment does not specifically limit this. Since the number of blades affects the amount of air guided, if a large amount of fresh air is actually required, the number of the first blades is greater than the number of the second blades, and if a small amount of fresh air is actually required, the number of the first blades is less than the number of the second blades.

[0162] In one embodiment, the ring is a circular ring, that is, a ring with a circular cross section. In other embodiments, the ring is a rectangular or irregular shape, as long as it is a closed and hollow shape.

[0163] Specifically, in one embodiment, the length of the first blade is between one half and one tenth of the length of the second blade, and preferably the length of the first blade is one quarter of the length of the second blade.

[0164] In an optional implementation of the embodiment of the present application, the air duct 8 is connected to a ventilation pipe 11, the ventilation pipe 11 is connected to an exhaust duct 12, and the exhaust duct 12 is connected to the external environment.

[0165] By adopting this implementation, the exhaust pipe 12 can be easily depressurized.

[0166] In the above-mentioned embodiments of the present application, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments. The steps shown in the relevant flow chart can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flow chart, in some cases, the steps shown or described can be executed in an order different from that here. In other words, the order of steps described in the foregoing embodiments is only an example, and it is also within the scope of protection of the embodiments of the present application to reasonably adjust the order of steps based on the content of the embodiments of the present application.

[0167] In a specific implementation of the embodiment of the present application, the deodorizing method, the control method and the clothing processing device of the clothing processing device include the following processing procedures:

[0168] like Figure 6 As shown, the arrow indicates the direction of airflow, so that when the fan is running, fresh air can be introduced to exchange with the internal circulating air. A washer-dryer with this structure can introduce fresh air and internal circulating air at the same time when the fan is rotating, which has a certain effect on purifying the air in the barrel. However, if the introduction of fresh air is continuously turned on, the power consumption in the deodorization stage will increase. Among them, the deodorization stage is optional. When the user is washing clothes, he can choose whether to add the deodorization function. If selected, the deodorization will be performed after the washing or drying is completed. The deodorization function can also be performed separately, just select it directly.

[0169] Combined with the double-suction fan 1 structure, under the attraction of the double-blade mechanism centrifuge, the fresh air is combined with the internal circulation air, and an odor sensor is added in the barrel. When the odor sensor recognizes the smell of mold, the fresh air is turned on, otherwise the fresh air is turned off or the fan speed is reduced to perform internal circulation. In this way, the fresh air ventilation function of the clothes is realized, and energy and electricity are saved.

[0170] like Figure 7-10 As shown in the figure, the control method and the whole device diagram after adding the odor sensor, the clothing processing device includes a box body 5, an outer drum 6, an inner drum 7, an air duct 8, an electric heater 9, a vent pipe 11, an exhaust duct 12 and an exhaust port 13. The odor sensor is mainly composed of an electronic nose system, which is a highly sensitive gas sensor that can accurately identify a variety of odors, including moldy odors. For cost considerations, this solution is only a moldy odor detection sensor. The working principle is to store the moldy odor level in the electronic nose system through the built-in sensor array and advance sampling. The sampling method can be manual or automatic sampling.

[0171] In the fresh air deodorization stage, the odor sensor will automatically start and use the electronic nose system to detect whether there is a musty smell in the indoor air. If the musty odor level detected by the system reaches or exceeds the musty odor level threshold W1 preset in the sensor, that is, W≥W1, the fresh air function will automatically turn on. At this time, the fresh air system will introduce fresh air from the outside, and gradually replace the musty indoor air through efficient filtering and purification devices, thereby effectively removing the musty odor in the room.

[0172] When the musty odor level drops below or equal to another preset value W0, that is, W≤W0, in order to reduce the noise during machine operation, the system will automatically reduce the speed of the fresh air fan. This design not only ensures the continuous freshness of the indoor air, but also effectively reduces the operating noise of the fresh air system and improves the user experience. The fresh air fan will continue to run at a lower speed to continue to remove odors. Initially, for every 1 reduction in the musty odor level W, the fan speed will be reduced by 200rpm on the original basis until the detected musty odor level is completely reduced to 0. At this time, the fresh air fan will be completely turned off to ensure that the indoor air is in the best fresh state.

[0173] Alternatively, there is another way to adjust the fan speed, such as Figure 4 Control method: After turning on the fresh air fan, the musty odor level Wi will be obtained, and the fan speed will be adjusted to R accordingly. The musty odor level Wi+1 will be detected every Tmin, and Wi-Wi+1≥3? If so, it proves that the fresh air effect is very good at this time, and the fan speed will be appropriately reduced by 250 (Wi-Wi+1) rpm to save energy and reduce noise. If Wi-Wi+1<3, then Wi-Wi+1<1? If so, it proves that the fresh air fan has a poor effect on removing musty odors, and the fan speed can be appropriately reduced by 150 (Wi-Wi+1) rpm. If 1≤Wi-Wi+1<3, the fan speed reduction rate is maintained at 200 (Wi-Wi+1) rpm.

[0174] This is how to make adjustments.

[0175] In addition, the fresh air system also has intelligent temperature and humidity control functions, which can automatically adjust the amount of fresh air introduced according to changes in indoor temperature and humidity to maintain a comfortable indoor temperature and humidity environment. This series of intelligent control measures not only improves the energy efficiency of the fresh air system, but also greatly improves user satisfaction and comfort.

[0176] Note: The sensor built-in musty odor classification can be array detection or color indication. The sensor can be installed on the inner wall of the barrel, or on the outer wall of the barrel or a circle around the outer circumference of the barrel, but cannot be installed on the back wall of the barrel to avoid inflow and outflow of wind.
