Description

Technical Field

[0001] The present application relates to the technical field of fabric drying, and in particular to a drying method and control device for fabric processing equipment and a fabric processing equipment with a drying function. Background Art

[0002] Current drying equipment usually improves drying efficiency by adjusting the target frequency of the compressor to shorten the drying time. However, the actual drying time is not completely consistent with the displayed time of the drying equipment, which results in users being unable to obtain the fabric at the expected time. If the fabric is dried too early, it is easy for the fabric to become wrinkled in the drum, and if it is dried too late, it will delay the user's use. In some specific cases, users need to use the fabric after a very accurate time, which requires the use of the timed drying mode. However, the current timed drying mode is basically the same as other drying modes, which can only ensure that the drying ends at the set time, but cannot ensure the drying effect, and is prone to over-drying or under-drying. Summary of the invention

[0042] 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.

[0043] It should be understood that the "multiple" mentioned herein 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 the 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 solution of the embodiments of the present application, in the embodiments of the present application, the words "first", "second" and the like 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 the like do not limit the quantity and execution order, and the words "first", "second" and the like do not limit them to be necessarily different.

[0044] 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.

[0045] Since the timed drying mode of current drying equipment can only ensure that drying is completed at the set time, without judging the dryness of the fabric, it only unilaterally controls the drying time, so there is a possibility of over-drying or under-drying.

[0046] In order to solve the above technical problems, the embodiments of the present application provide a drying method of a fabric processing device, a control device and a fabric processing device with a drying function, wherein the drying method includes:

[0047] Acquiring fabric property information, the fabric property information at least including a first fabric weight before drying;

[0048] The drying parameters in the drying process are controlled based on the target drying time and the fabric property information, and the drying parameters at least include the target frequency of the compressor.

[0049] This embodiment adjusts the drying parameters during the drying process according to the target drying time set by the user and the fabric property information including at least the first fabric weight before entering the drying process, thereby achieving the control of the moisture content and the temperature inside the drum during the drying process, ensuring that the fabric can reach a dry state after the target drying time is reached, avoiding the situation where the fabric is over-dried or not dry, and improving the user experience.

[0050] First, a brief introduction is given to the implementation subject of the embodiments of the present application.

[0051] The drying method of this embodiment is applied to a fabric processing device having a drying function. The fabric processing device may have only a drying function or may have both a washing function and a drying function.

[0052] The fabric treatment device comprises a shell, an outer cylinder and a fabric treatment cylinder, wherein the outer cylinder is arranged in the shell, and the fabric treatment cylinder is rotatably arranged in the outer cylinder. The cylinder wall of the outer cylinder is provided with an air outlet, the cylinder mouth of the fabric treatment cylinder is provided with a door seal, and the door seal is provided with an air inlet, and the cylinder wall of the fabric treatment cylinder is provided with a plurality of flow holes, and the plurality of flow holes can allow airflow and / or water flow to flow between the outer cylinder and the fabric treatment cylinder.

[0053] The fabric processing device further includes an air duct assembly, which is arranged in the space between the shell and the outer cylinder, preferably arranged above the outer cylinder. The air duct assembly includes an air inlet duct, an air outlet duct and a fan, the air outlet duct connects the air outlet with the air inlet end of the fan, and the air inlet duct connects the air outlet of the fan with the air inlet.

[0054] The fabric treatment device also includes a heat pump assembly, which is used to dehumidify the airflow in the air duct assembly. The heat pump assembly includes a compressor, an evaporator, a throttling device and a condenser. The compressor is arranged in the space between the shell and the outer cylinder, preferably at the bottom of the outer cylinder. The evaporator and the condenser are integrated in the two-device box body, and the two-device box body is located between the fan and the air inlet duct, and the condenser is arranged close to the air inlet duct. The compressor, the condenser, the throttling device and the evaporator are connected in sequence to form a refrigerant circulation loop.

[0055] During the fabric drying process, under the action of the fan, the hot and humid airflow entering the air duct assembly is blown toward the evaporator, and after the evaporator absorbs heat and condenses, it forms dry cold air, which is heated by the condenser to form high-temperature airflow, which eventually enters the fabric treatment drum to dry the fabric in the fabric treatment drum. When the heat pump assembly is turned on, the compressor is in the starting state to allow the refrigerant to circulate in the refrigerant circulation flow path.

[0056] The fabric processing equipment also includes a first temperature detection device and a second temperature detection device, wherein the first temperature detection device is arranged at the air inlet of the fabric processing cylinder to detect the air inlet temperature of the fabric processing cylinder, and the second temperature detection device is arranged at the air outlet of the fabric processing cylinder to detect the air outlet temperature of the fabric processing cylinder.

[0057] The technical solution of this embodiment is described in detail below in conjunction with the accompanying drawings. The following implementation modes and examples may be combined with each other if there is no conflict.

[0058] This embodiment proposes a drying method for a fabric processing device, referring to Figure 1 Flow chart of the present invention, the drying method comprises the following steps:

[0059] S11. Before entering the drying process, obtain fabric property information.

[0060] Specifically, before the fabric processing device with a drying function starts to dry the fabric, it first obtains the drying fabric property information, and the fabric property information at least includes the first fabric weight before entering the drying process, that is, the first fabric weight is the weight of the wet fabric before drying. The first fabric weight can be obtained by directly weighing or by calculating according to the motor current value, which is not specifically limited here.

[0061] It should be noted that, the term "before entering the drying process" in this embodiment refers to before the drying airflow is introduced into the fabric processing drum.

[0062] In one example, the fabric is first subjected to a washing process and then to a drying process. After the dehydration stage of the washing process and before entering the drying process, the fabric weight obtained by weighing the fabric is the first fabric weight. In another example, the drying process includes a dehydration stage and a drying stage that are executed successively. After the user starts the drying process, the dehydration stage is executed first. After the dehydration stage ends and before entering the drying stage, the fabric weight obtained by weighing the fabric is the first fabric weight.

[0063] In other achievable ways, the first fabric weight may also be the weight of wet fabric without dehydration, which is not specifically limited here. In addition, the first and second fabric weights described in this application are not for different fabrics, but for the weights of fabrics obtained at different stages.

[0064] S12. Controlling drying parameters during the drying process based on the target drying time and fabric property information, wherein the drying parameters at least include a target frequency of the compressor.

[0065] Specifically, the user determines the target drying time according to the needs before starting the drying program, or the user determines the target drying time by starting the timed drying mode. The target drying time is the time required by the user for the fabric processing device to complete drying within this time. After the target drying time is determined, when the user's control instruction to start drying is received, the target drying time is combined with the fabric attribute information to control the drying parameters in the drying process, thereby controlling the moisture content and drying temperature of the fabric in the drying process, so that the fabric is in a dry state when the target drying time is reached, and will not be over-dried or under-dried, thereby ensuring the drying effect.

[0066] The drying parameters at least include a target frequency of the compressor.

[0067] In one example, the drying time range to which the target drying time belongs, the fabric weight range to which the first fabric weight belongs, and the target frequency of the compressor have a first corresponding relationship. In the first corresponding relationship, the longer the drying time, the smaller the target frequency of the compressor corresponding to the drying time range, and the larger the first fabric weight, the larger the target frequency of the compressor corresponding to the fabric weight range.

[0068] This is because, under the same target drying time, the greater the weight of the first fabric, the more fabrics in the drum, and the greater the target frequency of the required compressor. Conversely, under the same target drying time, the smaller the weight of the first fabric, the less fabrics in the drum, and the smaller the target frequency of the required compressor. Moreover, under the same first fabric weight, the shorter the target drying time, the higher the required drying temperature in the drum, and the greater the target frequency of the compressor; conversely, under the same first fabric weight, the longer the target drying time, the lower the required drying temperature in the drum, and the smaller the target frequency of the compressor.

[0069] The drying parameters in the drying process are controlled based on the target drying time and fabric property information, including: before entering the drying process, determining the target frequency of the compressor according to the first corresponding relationship, and during the drying process, controlling the compressor to operate at the target frequency.

[0070] Referring to the first corresponding relationship table in Table 1 below, after determining the target drying time and the first fabric weight, the corresponding target frequency of the compressor can be obtained by looking up the table. During the drying process, the compressor is controlled to operate at the target frequency of the compressor determined by looking up the table.

[0071] Table 1:

[0072]

[0073] In Table 1, the size relationship of the target time range satisfies: Time3>Time2>Time1, the size relationship of the fabric weight range to which the second fabric weight belongs satisfies: Weight3>Weight2>Weight1, and the size relationship of the target frequency of the compressor satisfies: Fre3>Fre2>Fre1, Fre6>Fre5>Fre4, Fre9>Fre8>Fre7, Fre1>Fre4>Fre7, Fre2>Fre5>Fre8 and Fre3>Fre6>Fre9.

[0074] In other possible implementations, the drying parameters may also include fan speed, fabric processing drum speed, etc. The fan speed (or fabric processing drum speed) may also be determined based on the corresponding relationship between the drying time range to which the target drying time belongs, the fabric weight range to which the first fabric weight belongs, and the fan speed (or fabric processing drum speed). The longer the drying time, the smaller the fan speed (or fabric processing drum speed) corresponding to the drying time range, and the larger the first fabric weight, the greater the fan speed (or fabric processing drum speed) corresponding to the fabric weight range.

[0075] In an optional implementation, the drying method further includes: before entering the drying process, determining the dehydration speed of the fabric treatment drum before entering the drying process according to the target drying time. When the target drying time is greater than the set time, the fabric treatment drum is controlled to be dehydrated at a first speed before entering the drying process; when the target drying time is less than or equal to the set time, the fabric treatment drum is controlled to be dehydrated at a second speed before entering the drying process, wherein the first speed is less than the second speed; wherein the first fabric weight is the weight of the fabric after dehydration is completed before entering the drying process.

[0076] This embodiment controls the dehydration speed before entering the drying process according to the target drying time, thereby effectively controlling the moisture content of the fabric before entering the drying process, and preventing the fabric from being over-dried or under-dried after reaching the target drying time. For example, the time is set to 1 hour, and when the target drying time is greater than 1 hour, the dehydration speed is ≤1000rpm, and when the target drying time is ≤1 hour, the dehydration speed is greater than 1000rpm.

[0077] The dehydration in this embodiment can be performed after the user starts the drying program and before entering the drying process (i.e. before starting to introduce the drying airflow into the fabric processing drum). This situation can be applied to the case where the washing program and the drying program are performed in two independent fabric processing devices. The dehydration in this embodiment can also be performed during the dehydration stage in the washing program. This situation can be applied to the integrated washing and drying device. When the user selects the "wash + dry program", the target drying time of the drying program needs to be determined. After the target drying time is determined, the dehydration speed of the dehydration stage of the washing program is determined according to the target drying time, and dehydration is performed according to the determined dehydration speed in the dehydration stage of the washing program.

[0078] This embodiment determines the dehydration speed according to the target drying time to regulate the moisture content of the fabric before drying, thereby further ensuring the drying effect of the fabric when the target drying time is reached.

[0079] In other possible implementations, when the user sets the spin speed before entering the drying process, the spin cycle is directly performed according to the spin speed set by the user before entering the drying process.

[0080] In an optional implementation, referring to Figure 2 The drying method further comprises the following steps:

[0081] S21, during the fabric drying process, obtaining the air inlet temperature and air outlet temperature of the fabric treatment drum;

[0082] S22: when the temperature difference between the inlet air temperature and the outlet air temperature is greater than the set frequency modulation temperature difference, and the number of times the temperature difference is greater than the set frequency modulation temperature difference reaches the set number of times in a row, increase the target frequency of the compressor.

[0083] Specifically, after the compressor operating frequency is determined according to the target drying time set by the user and the first fabric weight, the compressor operates according to the target frequency after entering the drying process. Since the fabric weight changes continuously during the drying process, in order to further ensure the drying effect when the target drying time is reached, the inlet air temperature and the outlet air temperature are obtained in real time or periodically during the drying process, and the target frequency of the compressor is adjusted according to the temperature difference between the inlet air temperature and the outlet air temperature to adapt to the change in fabric weight.

[0084] After determining the temperature difference between the inlet air temperature and the outlet air temperature, if the temperature difference between the inlet air temperature and the outlet air temperature is greater than the set frequency modulation temperature difference, and the number of times it is greater than the set frequency modulation temperature difference reaches the set number of times in a row, it means that the temperature rise efficiency is slow at this time, and the fabric may not be dry when the target drying time is reached. At this time, the target frequency of the compressor can be appropriately increased, for example, the target frequency of the compressor can be increased by a set value, or the target frequency of the compressor can be increased by one level.

[0085] When the temperature difference between the inlet air temperature and the outlet air temperature is less than or equal to the set frequency modulation temperature difference, or when the temperature difference between the inlet air temperature and the outlet air temperature is greater than the set frequency modulation temperature difference, and the number of times it is continuously greater than the set frequency modulation temperature difference does not reach the set number, the target frequency of the compressor will not be adjusted.

[0086] After the target frequency of the compressor is increased, it is necessary to obtain the inlet air temperature and the outlet air temperature again in real time or periodically, and reach the set frequency modulation temperature difference based on the temperature difference between the newly obtained inlet air temperature and the outlet air temperature, and the target frequency of the compressor is increased when the number of times the set frequency modulation temperature difference is reached reaches the set number of times in succession. After the target frequency of the compressor is increased to the maximum operating frequency that can ensure the normal operation of the compressor, the target frequency of the compressor will no longer be increased, and the drying process can be accelerated by increasing the fan speed and the speed of the fabric processing drum during the drying process.

[0087] In an optional implementation, the set frequency modulation temperature difference, the set number of times, and the fabric weight range to which the first fabric weight belongs have a preset corresponding relationship; the larger the first fabric weight, the larger the fabric weight range corresponding to the set frequency modulation temperature difference, and the larger the first fabric weight, the smaller the set number of times corresponding to the fabric weight range corresponding to the first fabric weight.

[0088] This is because the heavier the fabric, the harder it is to dry, so a larger set frequency modulation temperature difference and a smaller set number of times are needed to adjust the compressor's target frequency to avoid the fabric not being completely dried after the target drying time is reached. Similarly, the lighter the fabric, the easier it is to dry, so a smaller set frequency modulation temperature difference and a larger set number of times are needed to adjust the compressor's target frequency to avoid the fabric being over-dried after the target drying time is reached.

[0089] Referring to the corresponding relationship between the set frequency modulation temperature difference, the set number of times and the fabric weight range to which the first fabric weight belongs in Table 2 below, when the first fabric weight is determined, the corresponding set frequency modulation temperature difference and the set number of times can be obtained by looking up the table.

[0090] Table 2:

[0091] First fabric weight Setting frequency modulation temperature difference Setting times Weight1 Temp4 Times4 Weight2 Temp5 Times5 Weight3 Temp6 Times6

[0092] In Table 2, the size relationship of the fabric weight range to which the first fabric weight belongs satisfies: Weight3>Weight2>Weight1, the size relationship of the set frequency modulation temperature difference satisfies: Temp6>Temp5>Temp4, and the size relationship of the set times satisfies: Times4>Times5>Times6.

[0093] In an optional implementation, referring to Figure 3 The drying method further comprises the following steps:

[0094] S31, before the fabric drying time reaches the target drying time, determining whether a drying condition is met;

[0095] S32, when the dryness determination condition is met, adjusting the target frequency of the compressor according to the weight of the second fabric in the drying process;

[0096] S33, controlling the compressor to operate at the adjusted frequency within the remaining drying time.

[0097] Specifically, during the drying process, the fabric is judged to be dry in real time to determine whether the dryness condition is met. If it is determined that the fabric has met the dryness condition before the target drying time is reached, it means that the fabric is close to being dry. At this time, the target frequency of the compressor needs to be adjusted according to the second fabric weight in the drying process to avoid the fabric from being over-dry after the target drying time is reached, and also to avoid the fabric from being wrinkled in the drum due to premature drying.

[0098] The second fabric weight is the fabric weight detected in real time after the drying airflow is introduced into the fabric processing drum. As the drying proceeds, the second fabric weight shows a trend of continuously decreasing.

[0099] Exemplarily, the fabric weight range to which the second fabric weight belongs has a second corresponding relationship with the target frequency of the compressor. In the second corresponding relationship, the fabric weight range with a larger second fabric weight corresponds to a smaller target frequency of the compressor. This is because, the larger the second fabric weight, the higher the frequency at which the compressor continues to operate after the dryness is determined, so that the temperature in the drum can be kept relatively stable, thereby preventing wrinkles from forming in the drum after the fabric is cooled. By ensuring that the fabric is dried to a just-right degree when the target drying time is reached, over-drying or under-drying can be prevented.

[0100] Wherein, under the same fabric weight, the target frequency of the compressor in the first corresponding relationship is greater than the target frequency of the compressor in the second corresponding relationship. Under the same fabric weight condition, the compressor is operated at a relatively large target frequency when just entering the drying process to avoid the situation where the fabric is not dry when the target drying time is reached. Under the same fabric weight condition, when the dryness judgment condition is met, a relatively small target frequency of the compressor is used to avoid the situation where the fabric is over-dry when the target drying time is reached.

[0101] When the dryness determination condition is met, adjusting the target frequency of the compressor according to the second fabric weight in the drying process includes: adjusting the target frequency of the compressor according to the second corresponding relationship.

[0102] Referring to the corresponding relationship table of the fabric weight range to which the second fabric weight belongs and the target frequency of the compressor in Table 3 below, when the second fabric weight is determined, the corresponding target frequency of the compressor can be obtained by looking up the table. During the drying process, the compressor is controlled to operate according to the target frequency of the compressor.

[0103] Table 3:

[0104]

[0105] In Table 3, the size relationship of the fabric weight range to which the second fabric weight belongs satisfies: Weight3>Weight2>Weight1, and the size relationship of the target frequency of the compressor satisfies: Fre12>Fre11>Fre10.

[0106] In an optional implementation, referring to Figure 4 The steps to determine whether the dryness condition is met are as follows:

[0107] S41, determining a dryness determination temperature difference and a dryness determination number according to the first fabric weight;

[0108] S42, obtaining the air inlet temperature and air outlet temperature of the fabric processing drum;

[0109] S43: When the temperature difference between the inlet air temperature and the outlet air temperature reaches the dry determination temperature difference, and the number of times the dry determination temperature difference is reached reaches the dry determination number, it is determined that the dry determination condition is met.

[0110] Specifically, before entering the drying process, the drying temperature difference and the drying times are determined based on the first fabric weight obtained. In one example, the fabric weight range to which the first fabric weight belongs, the drying temperature difference and the drying times have a preset corresponding relationship. The fabric weight range with a larger first fabric weight has a smaller drying temperature difference; the fabric weight range with a larger first fabric weight has a greater drying times. This is because the larger the first fabric weight, the more difficult it is to dry. A smaller drying temperature difference and a larger drying times are needed to ensure that the fabric is in a relatively dry state when the drying conditions are met, so as to avoid the fabric not being dry when the target drying time is reached. On the contrary, the smaller the first fabric weight, the easier it is to dry. A larger drying temperature difference and a smaller drying times are needed to avoid over-drying the fabric.

[0111] During the fabric drying process, the inlet air temperature and the outlet air temperature of the fabric processing drum are obtained in real time or periodically, and the drying is judged according to the drying temperature difference and the number of drying times determined according to the first fabric weight. When the temperature difference between the inlet air temperature and the outlet air temperature reaches the drying temperature difference, and the number of times the drying temperature difference is reached reaches the number of drying times, it is determined that the fabric has reached a relatively dry state, so that when the target drying time is reached, the fabric is at a just dry degree, and the fabric will not be over-dried or not dry.

[0112] Referring to the corresponding relationship table of the fabric weight range, the drying temperature difference and the drying times to which the first fabric weight belongs in Table 4 below, when the first fabric weight is determined, the corresponding drying temperature difference and the drying times can be obtained by looking up the table. During the drying process, the drying is performed according to the determined drying temperature difference and the drying times.

[0113] Table 4:

[0114] First fabric weight Drying temperature Number of dryness tests Weight1 Temp1 Times1 Weight2 Temp2 Times2 Weight3 Temp3 Times3

[0115] In Table 4, the size relationship of the fabric weight range in which the first fabric weight is located satisfies: Weight3>Weight2>Weight1, the size relationship of the dry judgment temperatures satisfies: Temp3<Temp2<Temp1, and the size relationship of the dry judgment times satisfies: Times3>Times2>Times1.

[0116] In a specific implementation of the embodiment of the present application, refer to Figure 5 The fabric drying method includes the following processing steps:

[0117] S501, running the timed drying mode;

[0128] In general, this embodiment automatically adjusts the target frequency of the compressor during the drying process by combining the target drying time set by the user with the first fabric weight before drying. At the same time, if the user does not set the dehydration speed, the dehydration speed before entering the drying process is determined according to the target drying time, and the moisture content of the fabric before entering the drying process is effectively controlled, thereby further ensuring the drying effect of the fabric when the target drying time is reached. During the fabric drying process, the target frequency of the compressor is further adjusted in real time in combination with the second fabric weight in the drying process and the temperature difference between the inlet and outlet temperatures, so as to ensure that the fabric is just dry when the target drying time is reached, to prevent the problem of over-drying or under-drying, and to improve the user experience.
