[0037] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0038] Considering that the difference between a washer-dryer and a washing machine lies in the additional drying system of the washer-dryer. The drying system of a water-cooled washer-dryer only serves the purpose of drying and caring for clothes. The scheme of the present invention is aimed at a water-condensing washer-dryer with electric air heating, and proposes a control method for a washer-dryer, specifically a heating control method for a water-condensing washer-dryer, which intervenes the drying system in the washing procedure to deal with the situation where the heating performance of the water-electric heating element of the washer-dryer (such as a drum washing machine) is weakened or even fails, causing the whole machine alarm, or the washing effect of the water-electric heating element of the washer-dryer (such as a drum washing machine) is reduced, or even the whole washer-dryer (such as a drum washing machine) The machine alarm.

[0039] According to an embodiment of the present invention, a control method for a washer-dryer is provided. Figure 1 A flow chart of an embodiment of the method of the present invention is shown. The integrated washer-dryer can operate in a heating washing stage and a drying stage. A water-electric heating element is provided in the heating washing stage, and an air-electric heating element, a fan and a condensing element are provided in the drying stage. The water-electric heating element can electrically heat water in water, and the air-electric heating element can electrically heat air in air. The control method of the integrated washer-dryer includes steps S110 to S140.

[0040] In step S110, when the washer-dryer is operating in the heating and washing stage, the operating parameters of the hydroelectric heating element are obtained.

[0041] In step S120, it is determined whether the working state of the hydroelectric heating element is normal according to the working parameters of the hydroelectric heating element.

[0042] In some embodiments, the working parameters of the hydroelectric heating element include: hydroelectric heating power, and the rising temperature of the washing water temperature per unit time.

[0043] For the specific process of determining whether the working state of the hydroelectric heating element is normal according to the working parameters of the hydroelectric heating element in step S120, please refer to the following exemplary description.

[0044] Combine the following Figure 2 The flowchart of an embodiment of determining whether the working state of the hydroelectric heating element is normal in the method of the present invention is shown, which further illustrates the specific process of determining whether the working state of the hydroelectric heating element is normal in step S120, including: step S210 to step S230.

[0045] Step S210, determining whether the hydroelectric heating power exceeds the preset heating power, and determining whether the rising temperature of the washing water temperature within the unit time is lower than the preset rising temperature.

[0046] Step S220: If it is determined that the hydroelectric heating power does not exceed the preset heating power, and the rising temperature of the washing water temperature within the unit time is not lower than the preset rising temperature, it is determined that the working state of the hydroelectric heating element is normal.

[0047] Step S230: If it is determined that the hydroelectric heating power exceeds the preset heating power, and / or it is determined that the rising temperature of the washing water temperature within the unit time is lower than the preset rising temperature, it is determined that the working state of the hydroelectric heating element is abnormal.

[0048] Specifically, Fig. 9 FIG. 1 is a flow chart of an embodiment of a heating control method for a washer-dryer. Fig. 9 As shown, the electric heating control method of the washer-dryer includes:

[0049] Step 1: When the user selects a washing program that requires heating, that is, the user selects a temperature-related washing program, such as a heating washing program that heats to a certain temperature for washing.

[0050] Step 2: When the heating washing program selected by the user runs to the heating step, determine whether the water and electricity heating element of the heating washing program is normal. If so, continue to execute the heating washing program, that is, continue the washing work. If not, execute step 3.

[0051] Among them, when judging whether the water-electric heating element of the heating washing program is normal, it can be specifically judged by judging whether the heating power of the water-electric heating element in the heating washing stage exceeds the preset heating power, and whether the rising temperature of the washing water per unit time is lower than the preset rising temperature.

[0052] When the heating power of the hydroelectric heating element in the heating washing stage does not exceed the preset heating power, and the rising temperature of the washing water per unit time is not lower than the preset rising temperature, it is judged that the working state of the hydroelectric heating element in the heating washing program is a normal working state, and the heating washing program continues to be executed, that is, the washing work continues until it ends.

[0053] When the heating power of the hydroelectric heating element in the heating washing stage exceeds the preset power, or the rising temperature of the washing water per unit time is lower than the preset temperature, it is judged that the working state of the hydroelectric heating element in the heating washing program is an abnormal working state, and step 3 can be executed at this time.

[0054] At step S130, if it is determined that the working state of the hydroelectric heating element is normal, the washer-dryer is controlled to continue to perform heating and washing work under the heating of the hydroelectric heating element, that is, the washer-dryer is controlled to continue to work in the heating and washing stage and continue subsequent work.

[0055] At step S140, if it is determined that the working state of the water-electric heating element is abnormal, the water-electric heating element is controlled to stop working, and the air-electric heating element and the fan are controlled to start, and the condensing element is controlled not to start, so that the drying stage is intervened in the heating and washing stage to assist in the heating work of the heating and washing stage.

[0056] The solution of the present invention, when the heating performance of the water-electric heating element of the washer-dryer (such as a drum washing machine) is weakened, the air-electric heating element of the drying system of the washer-dryer (such as a drum washing machine) is used to auxiliary heat the washing water, so as to deal with the situation that the whole machine alarms due to the weakening or even failure of the heating performance of the water-electric heating element of the washer-dryer (such as a drum washing machine) or the washing effect of the water-electric heating element of the washer-dryer (such as a drum washing machine) is reduced or even the whole machine alarms of the washer-dryer (such as a drum washing machine), and ensure the washing effect of the clothes. Thus, the problem that when the user uses the heating washing program, the whole machine alarm may be caused by the abnormality of the water-electric heating element, thereby achieving the effect of improving the reliability of the whole machine.

[0057] In some embodiments, the control method of the washer-dryer described in the solution of the present invention further includes: a process of notifying a user of the abnormal working state of the hydroelectric heating element.

[0058] Combine the following Figure 3 The flowchart of an embodiment of notifying a user of a message that the working state of the hydroelectric heating element is abnormal in the method of the present invention further illustrates the specific process of notifying a user of a message that the working state of the hydroelectric heating element is abnormal, including: step S310 to step S320.

[0059] Step S310, before controlling the air electric heating element and the fan to start and controlling the condensing element not to start, displaying a message that the working state of the water-electric heating element is abnormal, and / or sending a message that the working state of the water-electric heating element is abnormal to the client APP to remind the user that the working state of the water-electric heating element is abnormal.

[0060] Step S320: If no user intervention instruction is received, the air electric heating element and the fan are controlled to start, and the condensing element is controlled not to start.

[0061] like Fig. 9As shown, the electric heating control method of the washing and drying machine also includes: step 3, when the working state of the water-electric heating element of the heating washing program is an abnormal working state, the working state of the water-electric heating element of the heating washing program is displayed as an abnormal working state, or the working state of the water-electric heating element of the heating washing program is sent to the client APP to notify the user. When the user knows that the working state of the water-electric heating element of the heating washing program is an abnormal working state, the user can choose to check and maintain the working state of the water-electric heating element of the heating washing program as an abnormal working state, so as to facilitate the subsequent normal use of the water-electric heating element in the heating washing program for heating, and also to extend the service life of the washing and drying machine. That is to say, when it is judged that the working state of the water-electric heating element of the heating washing program is an abnormal working state, the user can be informed of the abnormal situation of water heating through the display area icon or the APP, and after-sales maintenance can be sought according to actual needs, but it will not affect the subsequent normal washing and drying of the washing and drying machine.

[0062] In some embodiments, the control method of the washer-dryer described in the solution of the present invention also includes: a process of determining whether to drain the remaining washing water in the washing drum of the washer-dryer.

[0063] Combine the following Figure 4 The flowchart of an embodiment of the method of the present invention for determining whether to drain the remaining washing water in the washing drum of the washer-dryer is shown, further illustrating the specific process of determining whether to drain the remaining washing water in the washing drum of the washer-dryer, including: step S410 to step S440.

[0064] Step S410, before controlling the air electric heating element and the fan to start and controlling the condensing element not to start, obtaining the current water inlet stage of the heating and washing stage, and obtaining the current water level of the heating and washing stage.

[0065] Step S420, determining whether the current water inlet stage is a preset low water level stage, and / or determining whether the current water inlet stage has reached a target water level selected by a user.

[0066] Step S430, if it is determined that the current water inlet stage has reached the target water level, determine whether it is necessary to drain the current washing water in the washing drum of the washer-dryer according to the current water level, so as to control the air electric heating element and the fan to start according to the determination result, and control the condensing element not to start.

[0067] Step S440, if it is determined that the current water inlet stage is the low water level stage and the target water level has not been reached, the heating and washing stage is controlled to suspend water inlet, and according to the current water level, it is determined whether the current washing water in the washing drum of the washer-dryer needs to be drained, so as to control the air electric heating element and the fan to start according to the determination result, and control the condensing element not to start.

[0068] The control method of the washer-dryer provided by the solution of the present invention is mainly to control the electric heating work of the washer-dryer, so as to avoid the situation that during the heating and washing process, the whole washer-dryer will have a fault alarm or the washing time will be greatly increased because the water and electricity heating components of the washer-dryer fail or the heating effect becomes poor, so as to ensure the washing effect, which is conducive to improving the user experience, and solves the problem that when the user uses the heating washing program, the washing effect may be significantly reduced or the washing time is too long due to abnormal water and electricity heating. Therefore, the effect of improving the user experience is achieved, the stability and service life of the washer-dryer are improved, and the reliability of the electrical components in the drying electric heating and the drying system can be improved to a certain extent, thereby reducing after-sales work to a certain extent and improving the user experience. For example: when the water and electricity heating fails, the air electric heating can intervene to maintain the normal operation of the whole machine; for the user, it is equivalent to improving the electrical reliability.

[0069] In some embodiments, the specific process of determining whether the current washing water in the washing drum of the washer-dryer needs to be drained according to the current water level in steps S430 and S440 is described in the following exemplary embodiments.

[0070] Combine the following Figure 5 The method of the present invention is shown as a flow chart of an embodiment of determining whether it is necessary to drain the current washing water in the washing drum of the washer-dryer according to the current water level, further illustrating the specific process of determining whether it is necessary to drain the current washing water in the washing drum of the washer-dryer according to the current water level in step S430 and step S440, including: step S510 to step S530.

[0071] Step S510, determining whether the current water level is less than or equal to the target water level.

[0072] Step S520, if it is determined that the current water level is less than or equal to the target water level, it is determined that there is no need to drain the current washing water in the washing drum of the washer-dryer, and the air electric heating element and the fan are directly controlled to start, and the condensing element is controlled not to start.

[0073] Step S530, if it is determined that the current water level is greater than the target water level, it is determined that the current washing water in the washing drum of the washer-dryer needs to be drained, and after the current washing water in the washing drum of the washer-dryer is drained according to the set drainage method, the air electric heating element and the fan are controlled to start, and the condensing element is controlled not to start.

[0074] like Fig. 9 As shown, the electric heating control method of the washer-dryer also includes: step 4, if the user does not interfere with the washing process or does not repair the water-electric heating element in the heating washing stage, then when the working state of the water-electric heating element in the heating washing program is an abnormal working state, the water-electric heating element in the heating washing program is controlled to stop working, so that the drying system of the washer-dryer intervenes in the heating washing program of the washer-dryer.

[0075] Optionally, after determining that the working state of the water and electricity heating element of the heating washing program is an abnormal working state, since the clothes in the drum of the washer-dryer have fully absorbed water, if the water level in the drum is higher than the target water level, after draining the excess washing water in the drum, step 5 is performed to allow the drying system of the washer-dryer to intervene in the heating washing program of the washer-dryer. Specifically, draining the excess washing water in the drum can control the drainage process by the drainage time or the change of the water level frequency to ensure that there is no excess water in the drum. The water level frequency refers to a value that can reflect the water level.

[0076] Optionally, after determining that the working state of the hydroelectric heating element of the heated washing program is an abnormal working state, although the clothes in the drum of the washer-dryer have fully absorbed water, if the water level in the drum is lower than the target water level, there is no need to drain the excess washing water in the drum, but directly execute step 5 to allow the drying system of the washer-dryer to intervene in the heated washing program of the washer-dryer, thereby avoiding increasing water consumption.

[0077] Optionally, after determining that the working state of the hydroelectric heating element of the heating washing program is an abnormal working state, if the washing water level selected by the user is a high water level, but the working state of the hydroelectric heating element of the heating washing program has been determined to be an abnormal working state in the low water level stage, the water supply is stopped, and whether to drain the water is selected according to whether the water level in the drum is higher than the target water level or lower than the target water level, and then step 5 is executed to allow the drying system of the washer-dryer to intervene in the heating washing program of the washer-dryer.

[0078] In some embodiments, the control method of the washer-dryer described in the solution of the present invention also includes: a process of adjusting the degree of intervention of the drying system.

[0079] Combine the following Figure 6The flowchart of an embodiment of adjusting the degree of intervention of the drying system in the method of the present invention further illustrates the specific process of adjusting the degree of intervention of the drying system, including: step S610 to step S640.

[0080] Step S610, after controlling the air electric heating component and the fan to start and controlling the condensing component not to start, obtain the current measured temperature of the wet clothes in the washing drum of the washer-dryer, and obtain the current water level change frequency in the washing drum of the washer-dryer.

[0081] Step S620, determining whether the currently measured temperature of the wet laundry is greater than or equal to a set temperature.

[0082] Step S630: If it is determined that the currently measured temperature of the wet clothes is lower than the set temperature, the electric air heater and the fan are controlled to continue to operate to continue heating the wet clothes.

[0083] Step S640, if it is determined that the current measured temperature of the wet clothes is greater than or equal to the set temperature, the air electric heating element and the fan are controlled to stop working, and the degree of intervention of the drying system is adjusted according to the current water level change frequency in the washing drum.

[0084] like Fig. 9 As shown, the electric heating control method of the washer-dryer further includes:

[0085] Step 5: The drying system of the washer-dryer is involved in the heating and washing program of the washer-dryer, mainly to start the electric air heater and fan of the drying system, but the condensing part of the drying system does not participate in the work. By starting the electric air heater and fan of the drying system to heat the wet clothes in the drum, the water temperature sensor can more accurately measure the current temperature of the clothes and water, which is recorded as the temperature measured by the water temperature sensor.

[0086] Step 6: Determine whether the temperature measured by the water temperature sensor is greater than or equal to the set temperature T. If so, execute step 7, otherwise return to step 5 to continue heating the wet clothes in the drum. The set temperature T is the temperature parameter selected by the washing program, such as the set temperature T can be any suitable temperature among 30℃, 40℃, 50℃, and 60℃.

[0087] In some embodiments, the set temperature includes: a first threshold temperature or a second threshold temperature.

[0088] Wherein, if the set temperature is a first threshold temperature, then when the current measured temperature of the wet clothes is less than the first threshold temperature, the electric air heater and the fan are controlled to continue to work, so as to continue to heat the wet clothes. When the current measured temperature of the wet clothes is greater than or equal to the first threshold temperature, the electric air heater and the fan are controlled to stop working, and the degree of intervention of the drying system is adjusted according to the frequency of the current water level change in the washing drum.

[0089] If the set temperature is the second threshold temperature, then when the current measured temperature of the wet clothes is less than the second threshold temperature, if the current heating time of the wet clothes has not reached the set heating time, the air electric heating element and the fan are controlled to continue to work to continue heating the wet clothes. If the current heating time of the wet clothes has reached the set heating time, the air electric heating element and the fan are controlled to stop working, and the degree of intervention of the drying system is adjusted according to the current frequency of water level changes in the washing drum. When the current measured temperature of the wet clothes is greater than or equal to the second threshold temperature, the air electric heating element and the fan are controlled to stop working, and the degree of intervention of the drying system is adjusted according to the current frequency of water level changes in the washing drum.

[0090] In step 6, optionally, if the set temperature T is 30°C or 40°C, determine whether the temperature measured by the water temperature sensor is greater than or equal to the set temperature T. If so, execute step 7, otherwise return to step 5 to continue heating the wet clothes in the drum.

[0091] Optionally, if the set temperature T is higher, such as if the set temperature T is 50°C or 60°C, it can also be controlled in combination with the heating time. For example, if the heating time reaches the set heating time, even if the water temperature sensor measures a temperature lower than the set temperature T, the heating is stopped and step 7 is executed to avoid a significant increase in time consumption due to low heating effect or other abnormal conditions.

[0092] In some embodiments, the control method of the washer-dryer described in the solution of the present invention, the specific process of adjusting the degree of intervention of the drying system according to the current water level change frequency in the washing drum in step S640, see the following exemplary description.

[0093] Combine the following Figure 7 The flowchart of an embodiment of the method of the present invention for adjusting the degree of intervention of the drying system according to the current frequency of water level changes in the washing drum is shown, which further illustrates the specific process of adjusting the degree of intervention of the drying system according to the current frequency of water level changes in the washing drum in step S640, including: steps S710 to S730.

[0094] Step S710, determining whether the current water level change frequency in the washing tub is less than or equal to the set washing water level frequency.

[0095] Step S720, if it is determined that the current water level change frequency in the washing drum is less than or equal to the washing water level frequency, the washer-dryer is controlled to continue to perform heating and washing under the heating of the hydroelectric heating element, that is, the washer-dryer is controlled to continue to work in the heating and washing stage and continue subsequent work.

[0096] Step S730, if it is determined that the current water level change frequency in the washing drum is greater than the washing water level frequency, the water inlet setting time of the washer-dryer is controlled, and then returns to continue to control the air electric heating element and the fan to start, and control the condensing element not to start, so that the drying stage intervenes in the heating washing stage, and assists in realizing the heating work of the heating washing stage.

[0097] like Fig. 9 As shown, the electric heating control method of the washer-dryer further includes:

[0098] Step 7. When the temperature measured by the water temperature sensor is greater than or equal to the set temperature T, obtain the water level sensor measurement value, such as whether the water level frequency is less than or equal to the set washing water level frequency. If so, continue to execute the heating washing program, that is, continue the washing work until the end. Otherwise, execute step 8.

[0099] Step 8: When the water level frequency is greater than the set washing water level frequency, the washing and drying machine is controlled to set the water inlet time t1, and then returns to step 5 to continue heating the wet clothes in the drum. The set time t1 can be 10-15s. This gradual water inlet method makes the washing water temperature rise faster and more evenly. Of course, the specific water inlet time also needs to be determined according to the drum specifications and the water inlet valve specifications.

[0100] For example: drum specifications: For example, the drum volume of a 10kg machine and a 12kg machine is different. When the water is fed into the same water inlet valve, the speed of water level rise is also different. When the water level is raised, the water inlet time of the larger volume is longer. Water inlet valve specifications: Under the same drum specifications, the water valve with a flow rate of 7L / min and the water valve with a flow rate of 8L / min, when the water level is raised, the water valve with a larger flow rate needs a shorter water inlet time.

[0101] Of course, after the heating step is completed, the washing continues to complete the selected program. In this way, when the water-electric heating element of the washer-dryer is in an abnormal state, the air-electric heating element and the fan of the drying system are involved in the washing program to replace the water-electric heating element to heat the clothes and water, thereby avoiding the malfunction alarm of the whole machine when the water-electric heating element is abnormal, thereby improving reliability and service life.

[0102] The solution of the present invention provides a control method for a washer-dryer, which can detect the functional integrity of the water-electric heating component through self-test, such as whether the electric heating component in the washing stage of the washer-dryer can heat normally, to control whether the electric air heating and fan in the drying system are involved in the washing program, and can deal with the situation where the whole machine alarms or the washing effect is reduced due to the failure of the water-electric heating. Specifically, when the water-electric heating function is missing or damaged, the air electric heating and fan of the drying system intervene to ensure that the heating and washing in the washing process can be completed normally, and no fault alarms will occur at the level of the whole machine, thereby improving the reliability and service life of the whole machine and improving the user experience.

[0103] The technical solution of this embodiment is adopted. When the user selects the heating washing program of the washer-dryer, it is determined whether the working state of the water-electric heating element in the heating washing program is abnormal. If it is abnormal, the air electric heating element and the fan in the drying system of the washer-dryer are started to heat the wet clothes in the drum without user intervention and when the water level in the drum is not higher than the target water level. Thus, when the heating performance of the water-electric heating element of the washer-dryer (such as a drum washing machine) is weakened, the air electric heating element of the drying system of the washer-dryer (such as a drum washing machine) is used to auxiliary heat the washing water to ensure the washing effect of the clothes.

[0104] According to an embodiment of the present invention, a control device for a washer-dryer corresponding to the control method for the washer-dryer is also provided. Figure 8 A schematic diagram of the structure of an embodiment of the device of the present invention is shown. The integrated washer-dryer can operate in a heating washing stage and a drying stage. A water-electric heating element is provided in the heating washing stage, and an air-electric heating element, a fan and a condensing element are provided in the drying stage. The water-electric heating element can electrically heat water in water, and the air-electric heating element can electrically heat air in air. The control device of the integrated washer-dryer includes: an acquisition unit 102 and a control unit 104.

[0105] The acquisition unit 102 is configured to acquire the working parameters of the water-electric heating element when the washer-dryer is operating in the heating and washing stage. The specific functions and processing of the acquisition unit 102 refer to step S110.

[0106] The control unit 104 is configured to determine whether the working state of the hydroelectric heating element is normal according to the working parameters of the hydroelectric heating element. The specific functions and processing of the control unit 104 refer to step S120.

[0107] In some embodiments, the working parameters of the hydroelectric heating element include: hydroelectric heating power, and the rising temperature of the washing water temperature per unit time.

[0108] The control unit 104 determines whether the working state of the hydroelectric heating element is normal according to the working parameters of the hydroelectric heating element, including:

[0109] The control unit 104 is further configured to determine whether the water-electric heating power exceeds a preset heating power and whether the rising temperature of the washing water temperature in the unit time is lower than a preset rising temperature. The specific functions and processing of the control unit 104 are also shown in step S210.

[0110] The control unit 104 is further configured to determine that the working state of the hydroelectric heating element is normal if it is determined that the hydroelectric heating power does not exceed the preset heating power and the rising temperature of the washing water temperature within the unit time is not lower than the preset rising temperature. The specific functions and processing of the control unit 104 are also shown in step S220.

[0111] The control unit 104 is further configured to determine that the working state of the hydroelectric heating element is abnormal if it is determined that the hydroelectric heating power exceeds the preset heating power and / or the rising temperature of the washing water temperature within the unit time is lower than the preset rising temperature. The specific functions and processing of the control unit 104 are also shown in step S230.

[0112] Specifically, Fig. 9 FIG. 1 is a flow chart of an embodiment of a heating control device for a washer-dryer. Fig. 9 As shown, the electric heating control device of the washer-dryer comprises:

[0113] Step 1: When the user selects a washing program that requires heating, that is, the user selects a temperature-related washing program, such as a heating washing program that heats to a certain temperature for washing.

[0114] Step 2: When the heating washing program selected by the user runs to the heating step, determine whether the water and electricity heating element of the heating washing program is normal. If so, continue to execute the heating washing program, that is, continue the washing work. If not, execute step 3.

[0115] Among them, when judging whether the water-electric heating element of the heating washing program is normal, it can be specifically judged by judging whether the heating power of the water-electric heating element in the heating washing stage exceeds the preset heating power, and whether the rising temperature of the washing water per unit time is lower than the preset rising temperature.

[0116] When the heating power of the hydroelectric heating element in the heating washing stage does not exceed the preset heating power, and the rising temperature of the washing water per unit time is not lower than the preset rising temperature, it is judged that the working state of the hydroelectric heating element in the heating washing program is a normal working state, and the heating washing program continues to be executed, that is, the washing work continues until it ends.

[0117] When the heating power of the hydroelectric heating element in the heating washing stage exceeds the preset power, or the rising temperature of the washing water per unit time is lower than the preset temperature, it is judged that the working state of the hydroelectric heating element in the heating washing program is an abnormal working state, and step 3 can be executed at this time.

[0118] The control unit 104 is further configured to control the washer-dryer to continue to perform heating and washing under the heating of the hydroelectric heating element if it is determined that the working state of the hydroelectric heating element is normal, that is, to control the washer-dryer to continue to work in the heating and washing stage and continue subsequent work. The specific functions and processing of the control unit 104 are also shown in step S130.

[0119] The control unit 104 is further configured to control the water-electric heating element to stop working if it is determined that the working state of the water-electric heating element is abnormal, and control the air-electric heating element and the fan to start, and control the condensing element not to start, so that the drying stage is involved in the heating and washing stage, and assists in achieving the heating work of the heating and washing stage. The specific functions and processing of the control unit 104 are also shown in step S140.

[0120] The solution of the present invention, when the heating performance of the water-electric heating element of the washer-dryer (such as a drum washing machine) is weakened, the air-electric heating element of the drying system of the washer-dryer (such as a drum washing machine) is used to auxiliary heat the washing water, so as to deal with the situation that the whole machine alarms due to the weakening or even failure of the heating performance of the water-electric heating element of the washer-dryer (such as a drum washing machine) or the washing effect of the water-electric heating element of the washer-dryer (such as a drum washing machine) is reduced or even the whole machine alarms of the washer-dryer (such as a drum washing machine), and ensure the washing effect of the clothes. Thus, the problem that when the user uses the heating washing program, the whole machine alarm may be caused by the abnormality of the water-electric heating element, thereby achieving the effect of improving the reliability of the whole machine.

[0121] In some embodiments, the control device of the washer-dryer according to the solution of the present invention further includes: a process of notifying the user of the abnormal working state of the hydroelectric heating element, which is specifically as follows:

[0122] The control unit 104 is also configured to display a message indicating that the working state of the water-electric heating component is abnormal, and / or send a message indicating that the working state of the water-electric heating component is abnormal to the client APP before controlling the air-electric heating component and the fan to start and controlling the condensing component not to start, so as to remind the user that the working state of the water-electric heating component is abnormal. The specific functions and processing of the control unit 104 are also shown in step S310.

[0123] The control unit 104 is further configured to control the air electric heating element and the fan to start, and control the condensing element to not start, if no user intervention instruction is received. The specific functions and processing of the control unit 104 are also shown in step S320.

[0124] like Fig. 9 As shown, the electric heating control device of the washing and drying machine also includes: step 3, when the working state of the water-electric heating element of the heating washing program is an abnormal working state, the working state of the water-electric heating element of the heating washing program is displayed as an abnormal working state, or the working state of the water-electric heating element of the heating washing program is sent to the client APP to notify the user. When the user knows that the working state of the water-electric heating element of the heating washing program is an abnormal working state, the user can choose to check and maintain the working state of the water-electric heating element of the heating washing program as an abnormal working state, so as to facilitate the subsequent normal use of the water-electric heating element in the heating washing program for heating, and also to extend the service life of the washing and drying machine. That is to say, when it is judged that the working state of the water-electric heating element of the heating washing program is an abnormal working state, the user can be informed of the abnormal situation of water heating through the display area icon or the APP, and after-sales maintenance can be sought according to actual needs, but it will not affect the subsequent normal washing and drying of the washing and drying machine.

[0125] In some embodiments, the control device of the washer-dryer according to the solution of the present invention further includes: a process of determining whether to drain the remaining washing water in the washing drum of the washer-dryer, which is specifically as follows:

[0126] The acquisition unit 102 is further configured to acquire the current water inlet stage of the heating and washing stage and the current water level of the heating and washing stage before controlling the air electric heating element and the fan to start and controlling the condensing element to not start. The specific functions and processing of the acquisition unit 102 are also shown in step S410.

[0127] The control unit 104 is further configured to determine whether the current water inflow stage is a preset low water level stage, and / or determine whether the current water inflow stage has reached a target water level selected by the user. The specific functions and processing of the control unit 104 are also shown in step S420.

[0128] The control unit 104 is further configured to determine whether it is necessary to drain the current washing water in the washing drum of the washer-dryer according to the current water level if it is determined that the current water inlet stage has reached the target water level, so as to control the air electric heating element and the fan to start according to the determination result, and control the condensing element not to start. The specific functions and processing of the control unit 104 are also shown in step S430.

[0129] The control unit 104 is further configured to control the heating and washing stage to suspend water inflow if it is determined that the current water inflow stage is the low water level stage and the target water level has not been reached, and determine whether it is necessary to drain the current washing water in the washing drum of the washer-dryer according to the current water level, so as to control the air electric heating element and the fan to start according to the determination result, and control the condensing element not to start. The specific functions and processing of the control unit 104 are also shown in step S440.

[0130] The control device of the washer-dryer provided by the scheme of the present invention is mainly used to control the electric heating work of the washer-dryer to avoid the situation in which, during the heating washing process, the whole washer-dryer will have a fault alarm or the washing time will be greatly increased due to the failure of the water and electricity heating components of the washer-dryer or the heating effect becomes poor, so as to ensure the washing effect and help improve the user experience. It solves the problem that when the user uses the heating washing program, the washing effect may be significantly reduced or the washing time is too long due to abnormal water and electricity heating. Therefore, it achieves the effect of improving the user experience, improves the stability and service life of the washer-dryer, and to a certain extent can also improve the reliability of the drying electric heating and the electrical components in the drying system, thereby reducing after-sales work to a certain extent and improving the user experience.

[0131] In some embodiments, the control unit 104 determines whether it is necessary to drain the current washing water in the washing drum of the washer-dryer according to the current water level, including:

[0132] The control unit 104 is further configured to determine whether the current water level is less than or equal to the target water level. The specific functions and processing of the control unit 104 are also shown in step S510.

[0133] The control unit 104 is further configured to, if it is determined that the current water level is less than or equal to the target water level, determine that it is not necessary to drain the current washing water in the washing drum of the washer-dryer, directly control both the air electric heating element and the fan to start, and control the condensing element not to start. The specific functions and processing of the control unit 104 are also shown in step S520.

[0134] The control unit 104 is further configured to, if it is determined that the current water level is greater than the target water level, determine that the current washing water in the washing drum of the washer-dryer needs to be drained, and after the current washing water in the washing drum of the washer-dryer is drained according to the set drainage method, control the air electric heating element and the fan to start, and control the condensing element not to start. The specific functions and processing of the control unit 104 are also shown in step S530.

[0135] like Fig. 9 As shown, the electric heating control device of the washer-dryer also includes: step 4, if the user does not interfere with the washing process or does not repair the water-electric heating element in the heating washing stage, then when the working state of the water-electric heating element in the heating washing program is an abnormal working state, the water-electric heating element in the heating washing program is controlled to stop working, so that the drying system of the washer-dryer intervenes in the heating washing program of the washer-dryer.

[0136] Optionally, after determining that the working state of the water and electricity heating element of the heating washing program is an abnormal working state, since the clothes in the drum of the washer-dryer have fully absorbed water, if the water level in the drum is higher than the target water level, after draining the excess washing water in the drum, step 5 is performed to allow the drying system of the washer-dryer to intervene in the heating washing program of the washer-dryer. Specifically, draining the excess washing water in the drum can control the drainage process by the drainage time or the change of the water level frequency to ensure that there is no excess water in the drum. The water level frequency refers to a value that can reflect the water level.

[0137] Optionally, after determining that the working state of the hydroelectric heating element of the heated washing program is an abnormal working state, although the clothes in the drum of the washer-dryer have fully absorbed water, if the water level in the drum is lower than the target water level, there is no need to drain the excess washing water in the drum, but directly execute step 5 to allow the drying system of the washer-dryer to intervene in the heated washing program of the washer-dryer, thereby avoiding increasing water consumption.

[0138] Optionally, after determining that the working state of the hydroelectric heating element of the heating washing program is an abnormal working state, if the washing water level selected by the user is a high water level, but the working state of the hydroelectric heating element of the heating washing program has been determined to be an abnormal working state in the low water level stage, the water supply is stopped, and whether to drain the water is selected according to whether the water level in the drum is higher than the target water level or lower than the target water level, and then step 5 is executed to allow the drying system of the washer-dryer to intervene in the heating washing program of the washer-dryer.

[0139] In some embodiments, the control device of the washer-dryer according to the solution of the present invention further includes: a process of adjusting the degree of intervention of the drying system, which is specifically as follows:

[0140] The acquisition unit 102 is further configured to acquire the current measured temperature of the wet clothes in the washing drum of the washer-dryer and acquire the current water level change frequency in the washing drum of the washer-dryer after controlling the air electric heating element and the fan to start and controlling the condensing element to not start. The specific functions and processing of the acquisition unit 102 are also shown in step S610.

[0141] The control unit 104 is further configured to determine whether the current measured temperature of the wet laundry is greater than or equal to a set temperature. The specific functions and processing of the control unit 104 are also shown in step S620.

[0142] The control unit 104 is further configured to control the electric air heater and the fan to continue to operate to continue heating the wet clothes if it is determined that the current measured temperature of the wet clothes is less than the set temperature. The specific functions and processing of the control unit 104 are also shown in step S630.

[0143] The control unit 104 is further configured to control the electric air heater and the fan to stop working if it is determined that the current measured temperature of the wet clothes is greater than or equal to the set temperature, and adjust the degree of intervention of the drying system according to the current water level change frequency in the washing drum. The specific functions and processing of the control unit 104 are also shown in step S640.

[0144] like Fig. 9 As shown, the electric heating control device of the washer-dryer also includes:

[0145] Step 5: The drying system of the washer-dryer is involved in the heating and washing program of the washer-dryer, mainly to start the electric air heater and fan of the drying system, but the condensing part of the drying system does not participate in the work. By starting the electric air heater and fan of the drying system to heat the wet clothes in the drum, the water temperature sensor can more accurately measure the current temperature of the clothes and water, which is recorded as the temperature measured by the water temperature sensor.

[0146] Step 6: Determine whether the temperature measured by the water temperature sensor is greater than or equal to the set temperature T. If so, execute step 7, otherwise return to step 5 to continue heating the wet clothes in the drum. The set temperature T is the temperature parameter selected by the washing program, such as the set temperature T can be any suitable temperature among 30℃, 40℃, 50℃, and 60℃.

[0147] In some embodiments, the set temperature includes: a first threshold temperature or a second threshold temperature.

[0148] The control unit 104 is further configured to, if the set temperature is a first threshold temperature, control the electric air heater and the fan to continue to work to continue heating the wet clothes when the current measured temperature of the wet clothes is less than the first threshold temperature. When the current measured temperature of the wet clothes is greater than or equal to the first threshold temperature, control the electric air heater and the fan to stop working, and adjust the degree of intervention of the drying system according to the current water level change frequency in the washing drum.

[0149] The control unit 104 is further configured to, if the set temperature is a second threshold temperature, then when the current measured temperature of the wet clothes is less than the second threshold temperature, if the current heating time of the wet clothes has not reached the set heating time, control the air electric heating element and the fan to continue to work, so as to continue to heat the wet clothes. If the current heating time of the wet clothes has reached the set heating time, control the air electric heating element and the fan to stop working, and adjust the degree of intervention of the drying system according to the current frequency of water level changes in the washing drum. When the current measured temperature of the wet clothes is greater than or equal to the second threshold temperature, control the air electric heating element and the fan to stop working, and adjust the degree of intervention of the drying system according to the current frequency of water level changes in the washing drum.

[0150] In step 6, optionally, if the set temperature T is 30°C or 40°C, determine whether the temperature measured by the water temperature sensor is greater than or equal to the set temperature T. If so, execute step 7, otherwise return to step 5 to continue heating the wet clothes in the drum.

[0151] Optionally, if the set temperature T is higher, such as if the set temperature T is 50°C or 60°C, it can also be controlled in combination with the heating time. For example, if the heating time reaches the set heating time, even if the water temperature sensor measures a temperature lower than the set temperature T, the heating is stopped and step 7 is executed to avoid a significant increase in time consumption due to low heating effect or other abnormal conditions.

[0152] In some embodiments, the control unit 104 adjusts the degree of intervention of the drying system according to the frequency of current water level changes in the washing drum, including:

[0153] The control unit 104 is further configured to determine whether the current water level change frequency in the washing tub is less than or equal to the set washing water level frequency. The specific functions and processing of the control unit 104 are also shown in step S710.

[0154] The control unit 104 is further configured to control the washer-dryer to continue to perform heating and washing under the heating of the hydroelectric heating element if it is determined that the current water level change frequency in the washing drum is less than or equal to the washing water level frequency, that is, to control the washer-dryer to continue to work in the heating and washing stage and continue subsequent work. The specific functions and processing of the control unit 104 are also shown in step S720.

[0155] The control unit 104 is further configured to control the water inlet setting time of the washer-dryer if it is determined that the current water level change frequency in the washing drum is greater than the washing water level frequency, and then return to continue to control the air electric heating element and the fan to start, and control the condensing element not to start, so that the drying stage intervenes in the heating washing stage to assist in the heating work of the heating washing stage. The specific functions and processing of the control unit 104 are also shown in step S730.

[0156] like Fig. 9 As shown, the electric heating control device of the washer-dryer also includes:

[0157] Step 7. When the temperature measured by the water temperature sensor is greater than or equal to the set temperature T, obtain the water level sensor measurement value, such as whether the water level frequency is less than or equal to the set washing water level frequency. If so, continue to execute the heating washing program, that is, continue the washing work until the end. Otherwise, execute step 8.

[0158] Step 8. When the water level frequency is greater than the set washing water level frequency, control the washer-dryer to set the water inlet time t1, and then return to step 5 to continue heating the wet clothes in the drum. Among them, the set time t1 can be 10-15s. This gradual water inlet method makes the washing water warm up faster and more evenly. Of course, the specific water inlet time also needs to be determined based on the specifications of the drum and the water inlet valve. Of course, after the heating step is completed, continue washing to complete the selected program. In this way, when the water-electric heating element of the washer-dryer is in an abnormal state, the air electric heating element and the fan of the drying system are involved in the washing program, replacing the water-electric heating element to heat the clothes and water, avoiding the failure alarm of the whole machine when the water-electric heating element is abnormal, thereby improving reliability and service life.

[0159] The solution of the present invention provides a control device for a washer-dryer, which can detect the functional integrity of the water-electric heating element through self-test, such as whether the electric heating element in the washing stage of the washer-dryer can heat normally, to control whether the electric air heating and fan in the drying system are involved in the washing program, and can deal with the situation where the whole machine alarms or the washing effect is reduced due to the failure of the water-electric heating. Specifically, when the water-electric heating function is missing or damaged, the air electric heating and fan of the drying system intervene to ensure that the heating and washing in the washing process can be completed normally, and no fault alarms will occur at the level of the whole machine, thereby improving the reliability and service life of the whole machine and improving the user experience.
