[0004] Among them, the washing drum of the washer-dryer is equipped with a temperature-sensing package, that is, a temperature sensor and / or a temperature and humidity sensor, etc. When the temperature-sensing package in the washing drum fails, it will not affect the normal temperature washing of the washing machine. However, when the user needs to perform other washing operations such as warm water washing or high-temperature washing, the temperature-sensing package in the washing drum is damaged, resulting in the inability to obtain the heating temperature of the washing medium normally.

[0059] Embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.
[0060] like Figure 1 As shown, an exemplary embodiment of the present invention provides a clothes processing device. The clothes processing device may include but is not limited to a washing machine, and the washing machine may include but is not limited to a washing and care machine, a washing and drying machine, etc. For example, the washing machine may be a drum washing machine or a pulsator washing machine with drying or washing and care functions, and of course, the washing machine may also be other types of fully automatic washing machines.
[0061] It should be noted that, in one example, referring to Figure 1 As shown in the figure, the laundry processing device in the embodiment of the present invention is a washer-dryer 100. The washer-dryer 100 includes a washing drum 110, which may have a drying function and a washing function. The washing drum 110 is used to wash or dry the laundry 200, that is, the washing drum 110 may contain a washing medium, which may include but is not limited to washing water, etc.
[0062] In order to realize the drying function of the washing drum 110, a drying channel 120 connected to the washing drum 110 is further provided in the washer-dryer 100. One end of the drying channel 120 is connected to the air intake position of the washing drum 110, and the other end of the drying channel 120 is connected to the exhaust position of the drying airflow of the washing drum 110.
[0063] like Figure 1 As shown, the drying channel 120 may include an air inlet channel (not shown in the figure) and an air exhaust channel (not shown in the figure) connected to the washing drum 110, the air inlet channel is used to deliver the drying airflow to the washing drum 110, and the air exhaust channel is used to discharge the drying airflow from the washing drum 110. The drying channel 120 is provided with a temperature sensing component 400, and the temperature sensing component 400 at least includes a first temperature sensing element 410 and a second temperature sensing element 420. The first temperature sensing element 410 is used to obtain the temperature of the drying airflow entering the washing drum 110, and the second temperature sensing element 420 is used to obtain the temperature of the drying airflow discharged from the washing drum 110.
[0064] The first temperature sensing element 410 and the second temperature sensing element 420 are located at different positions outside the washing tub 110, and the spaces where the first temperature sensing element 410 and the second temperature sensing element 420 are located are connected to the inside of the washing tub 110, but the first temperature sensing element 410 and the second temperature sensing element 420 are not in contact with the washing medium.
[0065] In one example, the first temperature sensing element 410 is disposed on the upper side of the front of the washing drum 110, for example, in the air inlet passage in the drying passage 120, that is, the first temperature sensing element 410 is disposed at the air inlet position of the drying airflow. The second temperature sensing element 420 is disposed on the lower side of the rear of the washing drum 110, for example, in the air outlet passage in the drying passage 120, that is, the second temperature sensing element 420 is disposed at the exhaust position of the drying airflow.
[0066] The specific setting positions of the first temperature sensing element 410 and the second temperature sensing element 420 will vary with different washing machine models. Correspondingly, the temperature sampling values of the first temperature C1 obtained based on the first temperature sensing element 410 at different positions will also be different, and the temperature sampling values of the second temperature C2 obtained based on the second temperature sensing element 420 at different positions will also be different. Therefore, the specific temperature values of the first temperature C1 and the second temperature C2 are not specifically limited here.
[0067] It should be noted that the specific arrangement structure of the drying channel 120 in the washer-dryer 100 in this example is not specifically limited, that is, the first temperature sensing element 410 and the second temperature sensing element 420 can be set at any position outside the washing drum 110. The first temperature sensing element 410 and the second temperature sensing element 420 can include but are not limited to temperature sensors, temperature and humidity sensors, etc.
[0068] Continue to refer to Figure 1 As shown, in order to ensure and increase the inflow speed of the drying airflow in the air inlet channel, an induced draft fan 430 and the like may also be provided in the air inlet channel.
[0069] In order to meet the warm water washing operation or high temperature washing operation of the washer-dryer 100, a third temperature sensing element 300 and a heating element 500 are further provided in the washing tub 110. The third temperature sensing element 300 is used to obtain the temperature parameters of the washing medium.
[0070] The third temperature sensing element 300 may include but is not limited to a temperature sensor or a temperature and humidity sensor, etc. That is, the third temperature sensing element 300 can detect the temperature of the washing medium in the washing tub 110 in real time to ensure that the washer-dryer 100 can complete the warm water washing operation or high temperature washing operation of the clothes 200.
[0071] It should be noted that the third temperature sensing element 300 can be arranged at any position in the washing tub 110, wherein the number of the third temperature sensing element 300 can be one or more. When the number of the third temperature sensing element 300 is one, the third temperature sensing element 300 can be arranged at the middle position or other positions inside the washing tub 110. When the number of the third temperature sensing element 300 is multiple, the multiple third temperature sensing elements 300 can be respectively arranged on the top, bottom and side wall of the washing tub 110, etc., so as to obtain multiple temperature values through the multiple third temperature sensing elements 300, and take the average value of the multiple temperature values as the temperature value of the washing medium.
[0072] The heating element 500 is configured to heat the washing medium in the washing tub 110. In some embodiments, the heating element 500 may be an electrically heated drying heating tube, which may be disposed in the drying channel 120 so as to dry the washed clothes 200.
[0073] The determination of the temperature of the washing medium in the washer-dryer 100 is a very important and indispensable parameter, which can make the washing of the washer-dryer 100 more diverse. The accurate determination of the temperature of the washing medium will also make the cleaning ratio of the clothes higher, and it will also be easier to control the switching time of the heating tube 500 in the washer-dryer 100, thereby reducing unnecessary energy consumption.
[0074] In this example, when the third temperature sensing element 300 is in a faulty state, or when the detection data of the third temperature sensing element 300 is inaccurate, the third temperature sensing element 300 fails to detect the temperature of the washing medium in the washing drum 110. At this time, the temperature of the washing medium cannot be accurately determined, which will affect the subsequent washing operations of the washing drum 110, such as warm water washing operations or high temperature washing operations. Based on this, during the process of the heating element 500 heating the washing medium, the first temperature sensing element 410 and the second temperature sensing element 420 can be used to calculate the temperature of the washing medium in the washing drum 110, so that the temperature of the washing medium can be accurately determined, thereby ensuring that the washing drum 110 can normally perform subsequent warm water washing operations or high temperature washing operations, effectively improving the user experience.
[0075] It should be noted that the conversion process of the washing medium temperature based on the first temperature sensing element 410 and the second temperature sensing element 420 is described in the following control method of the clothes processing device.
[0076] like Figure 2 As shown, in some embodiments, an exemplary embodiment of the present invention provides a method for confirming the temperature of a washing medium. The method for confirming the temperature of a washing medium comprises the following steps:
[0077] Step S100: in the process of heating the washing medium based on the heating element, the temperature values of at least two positions outside the washing drum are obtained based on the temperature sensing component.
[0078] Step S200: performing weighted calculation based on the temperature correction strategy and the temperature values of at least two locations to obtain the temperature value of the washing medium, wherein the temperature correction strategy includes weights of the temperature values of at least two locations.
[0079] In step S100, at least two temperature values are obtained by using the temperature sensing component 400. In one example, the first temperature C1 and the second temperature C2 can be obtained by the temperature sensing component 400, that is, the at least two temperature values include the first temperature C1 and the second temperature C2. The first temperature C1 and the second temperature C2 respectively represent the temperature values at different positions outside the washing tub 110.
[0080] In step S200, the temperature value of the washing medium is obtained by weighted calculation using the first temperature C1 and the second temperature C2 and based on the corresponding temperature correction strategy. The temperature correction strategy includes weights of the temperature values of at least two positions. Based on this, the first temperature C1 and the second temperature C2 obtained outside the washing drum 110 are weighted calculated, and the temperature of the washing medium can be accurately determined based on the temperature correction strategy.
[0081] In this example, the temperature sensing component 400 can be used to convert the temperature of the washing medium in the washing drum 110, thereby accurately determining the temperature of the washing medium, thereby ensuring that the clothing processing device can perform normal warm water washing operations and high temperature washing operations, effectively improving the user experience.
[0082] The temperature correction strategy can be determined by the following methods:
[0083] First, the temperature rise rate of a target temperature sensing element among the first temperature sensing element 410 and the second temperature sensing element 420 is determined. The target temperature sensing element is any one of the first temperature sensing element 410 and the second temperature sensing element 420 , or the target temperature sensing element is the one with a higher position among the first temperature sensing element 410 and the second temperature sensing element 420 .
[0084] Then, the temperature correction strategy is determined according to the rate interval to which the temperature rise rate of the target temperature sensing element belongs, wherein different rate intervals correspond to different temperature correction strategies, and in different temperature correction strategies, the weights of the temperature values at at least two positions have different value ranges.
[0085] In the process of determining the temperature correction strategy according to the rate range to which the temperature rise rate of the target temperature sensing element belongs, the following methods can be used:
[0086] When the heating rate is in a rate interval greater than or equal to the rate threshold, the first temperature correction strategy is selected as the temperature correction strategy. The rate threshold can be 0.5°C. The heating rate is used to characterize the heating speed of the higher temperature value among at least two temperature values, that is, to represent the temperature increase value of the temperature value per unit time.
[0087] When the heating rate is in a rate interval less than the rate threshold, the second temperature correction strategy is selected as the temperature correction strategy. In the same temperature correction strategy, the weight of the temperature value of the higher position of at least two positions is greater than the weight of the temperature value of the lower position.
[0088] For example, refer to Figure 1 As shown in the figure, the setting position of the first temperature sensing element 410 is higher than the setting position of the second temperature sensing element 420, and the first temperature sensing element 410 is used to obtain the temperature of the drying airflow entering the washing drum 110, and the second temperature sensing element 420 is used to obtain the temperature of the drying airflow after the clothes 200 are dried. That is to say, the temperature value of the first temperature C1 obtained by the first temperature sensing element 410 is greater than the temperature value of the second temperature C2 obtained by the second temperature sensing element 420. At this time, the weight of the temperature value of the first temperature C1 is greater than the temperature value of the second temperature C2.
[0089] The temperature correction strategy includes a first weight factor and a second weight factor of the temperature values of at least two locations at different heating rates, wherein the weight of the temperature value of a single location is equal to the product of the first weight factor and the second weight factor of the single location.
[0090] The first weight factor of a single position reflects the influence ratio of the single position on the temperature of the washing medium in the at least two positions, and the sum of the influence ratios of the at least two positions on the temperature of the washing medium is 1.
[0091] The second weighting factor for the individual locations reflects the temperature loss from the wash medium to the individual locations.
[0092] In one example, in the first temperature correction strategy, the first weight factor K11 of the temperature value of the higher position of at least two positions satisfies 20%≤K11≤80%, and the second weight factor K1 satisfies 1.1≤K1≤1.2. The first weight factor K22 of the temperature value of the lower position of at least two positions satisfies 20%≤K22≤80%, and the second weight factor K2 satisfies 1.15≤K2≤1.25, wherein the sum of K11 and K22 is equal to 1.
[0093] In a specific example, it is taken that the at least two temperature values include a first temperature C1 acquired by the first temperature sensing element 410 and a second temperature C2 acquired by the second temperature sensing element 420 .
[0094] And, based on the comparison between the whole machine power P1 of the washer-dryer 100 and the power P2 of the heating tube 500, it is determined whether the heating element 500 has started the washing water heating. The power P2 of the heating tube 500 has a value range of 800W to 2500W, and the preferred value of the power P2 is 1800W. If the washer-dryer 100 adopts a 10Kg drum washer-dryer, the power P2 of the heating tube 500 is 1800W. When it is determined that the whole machine power P1 of the washer-dryer 100 is greater than the power P2 of the heating tube 500, it can be determined that the washing medium in the washing drum 110 has started the washing water heating.
[0095] The first temperature C1 and the second temperature C2 are acquired in real time based on the first temperature sensing element 410 and the second temperature sensing element 420, and the data of the first temperature C1 and the second temperature C2 are recorded by the control system of the washer-dryer 100. It should be noted that the control system of the washer-dryer 100 can adopt a control system in the prior art, as long as the control system can control various startup functions of the washer-dryer 100, and the specific structure type and specific control logic of the control system are not described in detail here.
[0096] Then, the increase value A of the first temperature C1 within the predetermined time is obtained. The increase value A is used to characterize the temperature increase data of the first temperature C1 within a time difference of one minute. For example, one minute ago, the first temperature obtained by the first temperature sensing element 410 is 40°C, and one minute later, the first temperature obtained by the first temperature sensing element 410 is 41°C, then the increase value A = (41°C - 40°C), that is, the increase value A is 1°C.
[0097] Due to the relationship between the boost value A and the preset value, the calculated temperature value of the washing medium in the washing tub 110 is determined. In this example, since the boost value A of the first temperature C1 is greater than 0.5°C, the temperature value of the washing medium is obtained based on the first temperature correction strategy and the weighted calculation of the first temperature C1 and the second temperature C2.
[0098] The process of determining the temperature value of the washing medium is as follows:
[0099] Since the heating rates of the heating tube 500 in the washer-dryer 100 are different, the value range of the first weight factor K11 of the first temperature C1 is 20% to 80%, and the preferred value is 55%; the value range of the second weight factor K1 is between 1.1 and 1.2, and preferably, the value of the second weight factor K1 is 1.15.
[0100] The value range of the first weight factor K22 of the second temperature C2 is 20% to 80%, and the preferred value is 45%; the value range of the second weight factor K2 is 1.15 to 1.25, and preferably, the value of the second weight factor K2 is 1.2.
[0101] The calculated value of the temperature of the washing medium is C = (C1×K1×K11)+(C2×K2×K22).
[0102] Therefore, within the time difference of one minute, the front and rear temperatures obtained based on the first temperature sensing element 410 are 39° C. and 40° C. respectively, that is, the increase value A is equal to 1° C. The second temperature C2 obtained based on the second temperature sensing element 420 is 38° C. At this time, the calculated temperature value C of the washing medium in the washing tub 110 = (40° C. × 1.15 × 0.55) + (38° C. × 1.2 × 0.45) = 45.82° C.
[0103] In the second temperature correction strategy, the first weight factor K33 of the temperature value of the higher position of at least two positions satisfies 20%≤K22≤80%, and the second weight factor K3 satisfies 1.05≤K3≤1.3. The first weight factor K44 of the temperature value of the lower position of at least two positions satisfies 20%≤K22≤80%, and the second weight factor K4 satisfies 1.1≤K4≤1.4, wherein the sum of K33 and K44 is equal to 1.
[0104] When the increase value A is less than 0.5° C., the temperature value of the washing medium is obtained based on the second temperature correction strategy and the weighted calculation of the first temperature C1 and the second temperature C2.
[0105] Among them, the temperature value of the washing medium C = (C3×K3×K33)+(C4×K4×K44).
[0106] When the lifting value A is less than 0.5° C., the calculation process of the temperature calculation value of the washing medium in the washing tub 110 may refer to the calculation process in the above example (ie, the lifting value A is greater than 0.5° C.), which will not be repeated here.
[0107] like Figure 3 As shown, a third temperature sensing element 300 is also provided in the washing drum 110, and the third temperature sensing element 300 is used to obtain the temperature parameters of the washing medium. The third temperature sensing element 300 may include but is not limited to a temperature sensor or a temperature and humidity sensor. In other words, the third temperature sensing element 300 can be used to detect the temperature of the washing medium in the washing drum 110 in real time to ensure that the washer-dryer 100 can complete the high-temperature washing operation of the clothes 200.
[0108] The third temperature sensing member 300 may be disposed at any position in the washing tub 110. The number of the third temperature sensing member 300 may be one or more. When the number of the third temperature sensing member 300 is one, the third temperature sensing member 300 may be disposed at the middle position or other positions inside the washing tub 110. When the number of the third temperature sensing member 300 is multiple, the multiple second temperature sensing members 300 may be respectively disposed on the top, bottom and side wall of the washing tub 110, etc., so as to obtain multiple temperature values through the multiple second temperature sensing members 300, and take the average value of the multiple temperature values as the temperature value of the washing medium.
[0109] Before the step of obtaining at least two temperature values by using the temperature sensing component 400, the control method of the clothes processing device of the present invention further includes the following steps:
[0110] The operating state of the third temperature sensing element 300 is acquired, wherein the operating state at least includes a fault state.
[0111] It is determined whether the operation state of the third temperature sensing element 300 is in a fault state, that is, the third temperature sensing element 300 is damaged or the detection effect is poor.
[0112] When the third temperature sensing element 300 is in a fault state, the temperature sensing assembly 400 is controlled to operate based on the process of the heating element 500 heating the washing medium.
[0113] Furthermore, when the third temperature sensing element 300 is in a fault state and the fault can be successfully recovered automatically, the fault is recovered automatically by the control system, and in the process of heating the washing medium by the heating element 500, the temperature value of the washing medium is detected by the third temperature sensing element 300 to control the washing tub 110 to run a normal washing process. The normal washing process is the normal procedure for washing clothes in the washing tub 110 when the third temperature sensing element 300 is in a normal state.
[0114] When the third temperature sensing element 300 is in a fault state and the fault cannot be successfully recovered, the temperature sensing component 400 is controlled to operate during the process of the heating element 500 heating the washing medium. The control system synchronously controls the washer-dryer 100 to issue a fault state alarm indication to remind the user to deal with the fault state of the third temperature sensing element 300 in time.
[0115] Based on this, when the third temperature sensing element 300 in the washing drum 110 is in a faulty state, the first temperature sensing element 410 and the second temperature sensing element 420 arranged on the outside of the washing drum 110 are used to accurately determine the temperature value of the washing medium in the washing drum 110 at this time based on the temperature correction strategy and the weighted calculation of the first temperature C1 and the second temperature C2, thereby ensuring that the washing medium is heated to the corresponding target value to ensure the washing effect of the clothes, effectively improving the washing ability of the washer-dryer 100 under warm water and high temperature water, and effectively improving the user experience.
[0116] At the same time, before the third temperature sensing component 300 is repaired or replaced, the warm water washing or high temperature washing function of the washer-dryer 100 can be temporarily used, which effectively improves the overall service life of the washer-dryer 100 while meeting the safety performance requirements of the washer-dryer 100.
[0117] like Figure 3 As shown, in some embodiments, when it is determined that the fault state of the third temperature sensing element 300 has not been restored, when the washing medium heating program is started, a judgment is made based on the target temperature value of the heating program and the temperature value of the higher temperature in at least two positions. It should be noted that the target temperature value of the heating program can be a temperature value issued by the control system of the washer-dryer 100. The issued temperature target value can be a temperature value set when the washing drum 110 performs warm water washing or high temperature washing. The temperature value can be the setting of the washer-dryer 110 when it leaves the factory, or it can be a value flexibly set by the user according to needs, which is not specifically limited here.
[0118] Reference Figure 3 As shown, in a specific example, the washing drum 110 of the washer-dryer 100 can run a clothes drying program, that is, a drying airflow can be delivered to the washing drum 110 through the air inlet channel in the drying channel 120, and the drying airflow can dry the clothes in the washing drum 110. The drying airflow after the drying process flows out of the washing drum 110 and is discharged through the exhaust channel. Take the first temperature C1 as an example, which is greater than the second temperature C2.
[0119] If the target temperature value is greater than the temperature value of the higher temperature, the heating element 500 is turned on when the inputted washing medium reaches the target water level to heat the washing medium.
[0120] That is, when the temperature target value is greater than the first temperature C1, it indicates that the temperature of the washing medium in the washing tub 110 is higher than the first temperature C1, that is, the temperature of the washing medium cannot meet the requirements of subsequent washing, and the washing medium needs to be heated. At this time, the washing medium can be heated by the heating element 500 after the water level of the washing medium reaches the target water level or during the process of the washing medium being input into the washing tub 110.
[0121] It should be noted that the target water level can be flexibly set according to the weight and / or type of the clothes. The target water level can be the set value of the washer-dryer 100 when it leaves the factory, or it can also be a water level value flexibly set by the user according to the clothes.
[0122] If the target temperature value is less than or equal to the temperature value of the higher position and the washing tub 110 has performed the laundry drying process for the first time, the heating element is turned on to heat the washing medium when the input washing medium reaches the target water level.
[0123] When the temperature target value is less than the first temperature C1, it indicates that the temperature of the washing medium in the washing tub 110 is lower than the first temperature C1, and the washing tub has performed the clothes drying process in the first time. When the water level of the washing medium does not reach the target water level, the washing medium needs to be transported into the washing tub 110. After the washing medium water level reaches the target water level, or during the process of the washing medium being transported into the washing tub 110, the heating element 500 is started to heat the washing medium.
[0124] The value range of the first time is 50 minutes to 80 minutes. Preferably, the first time can be set to 60 minutes.
[0125] If the target temperature value is less than or equal to the temperature value of the higher position, and the washing drum has not performed a clothes drying program within the first time, the washing drum is controlled to run a normal washing process.
[0126] When the temperature target value is less than the first temperature C1, it indicates that the temperature of the washing medium in the washing drum 110 is lower than the first temperature C1, and the washing drum has not performed a clothes drying program within the first time, then the washing drum 110 is controlled to run a normal washing process based on the control system.
