[0033] In order to enable a more detailed understanding of the features and technical contents of the embodiments of the present application, the implementation of the embodiments of the present application is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present application.

[0034] The present application embodiment provides a control method for a combined washer-dryer. Figure 1 This is a first flow chart of a control method for a combined washer-dryer in an embodiment of the present application, wherein the combined washer-dryer comprises a washing machine and a dryer, the dryer comprises a heat source module, and the washing machine comprises a washing machine air duct and a washing tub; wherein the heat source module is connected to the washing tub via the washing machine air duct.

[0035] like Figure 1 As shown, the control method of the combined washer-dryer may specifically include:

[0036] Step 101: Receive a drying instruction from the washing tub.

[0037] In a possible implementation, after the user takes out the washed clothes from the washing tub, the user starts the drying function of the washing tub through the application (Application, APP) of the terminal, or starts the drying function through the display screen or button of the washing machine, so as to receive the drying instruction of the washing tub. After receiving the drying instruction of the washing tub, the user responds to the drying instruction of the washing tub and performs the drying process of the washing tub.

[0038] In another possible implementation, after the washing process is finished, it is detected whether the washed clothes in the washing tub are taken out. If it is detected that the washed clothes in the washing tub are taken out, the drying function of the washing tub is automatically started.

[0039] In another possible implementation, the drying function of the washing tub is automatically started after the first preset time after the washing process ends. Here, the first preset time is the longest waiting time for the clothes to be taken out of the washing tub after the washing process ends. The first preset time can be customized according to the user's habit of operating clothes. For example, if the user is used to taking out the clothes from the washing tub more than ten minutes after the washing process ends, the first preset time can be set to half an hour.

[0040] Step 102: In response to the drying instruction, determine whether the washing machine door is in an open state.

[0041] Here, in response to the drying instruction of the washing tub, it is detected whether the washing machine door is in an open state. If it is detected that the washing machine door is in an open state, step 103 is executed.

[0042] In the prior art, a washing machine door is usually locked by an electronic lock when it is closed. Therefore, in one possible implementation, whether the washing machine door is open can be determined by identifying the locking state of the electronic lock; in another possible implementation, for example, if the washing machine door does not have an electronic lock, the current state of the washing machine door can be detected by utilizing sensing devices such as image sensors, distance sensors, and photoelectric sensors.

[0043] If it is detected that the washing machine door is in a closed state, in some embodiments, a prompt message is output to prompt the user to open the washing machine door.

[0044] For example, the user is prompted by voice to open the washing machine door, such as "entering the washing tub drying mode, please open the washing machine door". Alternatively, the signal light installed on the combined washing and drying machine flashes frequently to prompt the user to start the washing machine door, and voice prompts may also be provided. Alternatively, the washing machine door is automatically opened in the form of an electrical signal.

[0045] Step 103: The hot air generated by the heat source module is sent into the washing tub through the washing machine air duct for drying, and the air in the washing tub is discharged from the washing machine door.

[0046] Here, the hot air generated by the heat source module of the dryer is used to dry the residual moisture in the washing tub, so that there is no need to add an additional heat source module, thereby achieving the purpose of fully utilizing resources.

[0047] In addition, discharging the air in the washing tub from the washing machine door solves the problem of the washing machine not having a dedicated air outlet, while also avoiding the problem of excessive air pressure inside the washing tub.

[0048] In some embodiments, the washing tub includes an inner tub and an outer tub; step 103 may specifically include: sending the hot air generated by the heat source module into the space between the inner tub and the outer tub of the washing tub through the air duct of the washing machine for drying.

[0049] Here, the hot air generated by the heat source module of the dryer passes through the inner and outer barrels of the washing tub, drying the residual moisture in the inner and outer barrels, so that the washing tub remains dry and is not easy to breed bacteria.

[0050] Here, the execution entity of steps 101 to 103 may be a processor of the combined washer-dryer.

[0051] By adopting the above technical scheme, the hot air generated by the heat source module of the dryer is used to dry the residual moisture in the washing tub of the washing machine, and the air in the washing tub is discharged from the washing machine door. In this way, the washing machine does not need to add an additional heat source module, thereby achieving the purpose of full utilization of resources. At the same time, it also solves the problem that the washing machine is prone to breeding bacteria. This constitutes the first part of the inventive concept of this scheme.

[0052] Based on the above embodiments, the control method of the present application is applied to a combined washer-dryer. However, the applicant has found that in the prior art, the time required for drying by the dryer is usually longer, while the time required for drying the washing tub is usually shorter; and, the humidity of the clothes decreases faster in the early stage of drying, and the proportion of hot and humid air in the airflow is higher. This airflow with a large amount of hot and humid air is not very effective in drying the residual moisture in the washing tub. At the same time, introducing the drying airflow into the washing tub at this stage will cause the drying efficiency of the drying tub to decrease, ultimately leading to the problem that the drying process of the dryer is prolonged and the drying effect of the washing tub is not good. How to achieve efficient drying of the residual water in the washing machine without affecting the working process of the dryer has become a technical problem that needs to be solved in this field. In this regard, the present application specifically proposes a control method for a combined washer-dryer.

[0053] Figure 2 This is a second flow chart of the control method for a combined washer-dryer in an embodiment of the present application, wherein the combined washer-dryer includes a washing machine and a dryer, the dryer includes a heat source module, the washing machine includes a washing machine air duct and a washing tub, the washing machine air duct includes a centrifugal fan for delivering hot air into the washing tub; wherein the heat source module is connected to the washing tub via the washing machine air duct.

[0054] like Figure 2 As shown, the control method of the combined washer-dryer may specifically include:

[0055] Step 201: Receive a drying instruction from the washing tub.

[0056] Step 202: In response to a drying instruction, determine whether the washing machine door is in an open state.

[0057] Step 203: Determine whether the clothes dryer is in working state.

[0058] Step 204: When it is determined that the clothes drying process of the clothes dryer is in the late stage of drying, the centrifugal fan is started.

[0059] It should be noted that when the dryer is in working state, the dryer itself is full of hot air, and there is no need to start the heat source module separately. The hot air generated by the heat source module of the dryer is directly sent into the washing tub to dry the residual water in the washing tub. However, when the drying process of the dryer is in the early stage of drying, the dryer has a high demand for hot air. At this time, introducing hot air into the washing tub will divert the content of hot air in the dryer, resulting in a longer drying process. At the same time, the humidity of the hot air at this time is high, and the effect of drying the residual water in the washing tub is not good. Therefore, it is necessary to detect the stage of the drying process in real time. When it is determined that the drying process is in the later stage, the demand for hot air of the dryer is reduced, and the humidity of the hot air in the dryer is also reduced. At this time, the centrifugal fan built into the air path of the washing machine is started to send hot air into the washing tub for drying, so that the residual water in the washing machine can be dried without affecting the working process of the dryer, so as to achieve the purpose of full utilization of resources.

[0060] As for how to judge the stage of the drying process, in some embodiments, whether the drying process of the dryer is in the late drying stage is determined based on preset drying judgment indicators; wherein the preset drying judgment indicators include at least one of the following: air humidity in the drying barrel of the dryer, moisture content of clothes in the drying barrel, load weight of the drying barrel and drying time.

[0061] Here, the preset dryness judging index refers to an index used to judge the drying process of the clothes drying barrel. The more dryness judging indexes there are, the more accurate the stage of the drying process detected will be, and the impact on the operation of the clothes dryer will be reduced.

[0062] Here, at least one of the following sensors is built into the drying tub: an air humidity sensor, a moisture content sensor, and a weight sensor. The air humidity sensor is used to detect the air humidity in the drying tub. The moisture content sensor is used to detect the moisture content of the clothes in the drying tub. The weight sensor is used to detect the load weight of the drying tub. In addition, the load weight of the drying tub can also be detected by a motor.

[0063] In some embodiments, whether the drying process of the dryer is in the late drying stage is determined based on a preset drying judgment index, including: when the air humidity in the drying barrel meets the preset air humidity range, it indicates that the drying process is in the late drying stage; and / or, when the moisture content of the clothes in the drying barrel meets the preset moisture content range, it indicates that the drying process is in the late drying stage; and / or, when the load weight of the drying barrel meets the preset load weight range, it indicates that the drying process is in the late drying stage; and / or, when the drying time meets the preset time range, it indicates that the drying process is in the late drying stage.

[0064] Here, the preset air humidity range refers to the air humidity range in the drying barrel when the drying process is in the late drying stage. The preset moisture content range refers to the moisture content range of the clothes in the drying barrel when the drying process is in the late drying stage. The preset load weight range refers to the load weight range of the drying barrel when the drying process is in the late drying stage. The preset duration range refers to the duration that the drying process takes to be in the late drying stage.

[0065] The settings of the preset air humidity range, preset moisture content range, preset load weight range and preset time range can be calculated by repeatedly detecting the air humidity, moisture content, load weight and time of the drying barrel in the later stage of drying.

[0066] In some embodiments, after the centrifugal fan is started, the centrifugal fan is turned off after a preset time.

[0067] Here, the centrifugal fan is started to introduce hot air into the washing machine, and it runs for a preset time, such as 3-5 minutes, and then the centrifugal fan is automatically turned off, which saves resources to a certain extent.

[0068] Step 205: Use a centrifugal fan to send the hot air generated by the heat source module into the washing tub through the washing machine air duct for drying, and exhaust the air in the washing tub from the washing machine door.

[0069] Here, by starting the centrifugal fan, the hot air generated by the heat source module of the dryer is sent into the washing tub to dry the residual moisture in the washing tub, so that there is no need to add an additional heat source module, thereby achieving the purpose of fully utilizing resources.

[0070] In addition, discharging the air in the washing tub from the washing machine door solves the problem of the washing machine not having a dedicated air outlet, while also avoiding the problem of excessive air pressure inside the washing tub.

[0071] In some embodiments, the washing tub includes an inner tub and an outer tub; step 205 may specifically include: using a centrifugal fan to send the hot air generated by the heat source module through the air duct of the washing machine into the inner tub and the outer tub of the washing tub for drying.

[0072] Here, a centrifugal fan is used to send the hot air generated by the heat source module of the dryer into the washing tub, so that it passes through the inner tub and the outer tub, and dries the residual moisture in the inner tub and the outer tub, so that the washing tub remains dry and is not easy to breed bacteria.

[0073] In some embodiments, the heat source module includes an air inlet and a heater; the method also includes: using a centrifugal fan to suck air into the air inlet and heat it through the heater, and then sending the hot air generated by the heat source module into the washing tub through the washing machine air duct for drying.

[0074] In some embodiments, when it is determined that the washing machine door is in a closed state, the centrifugal fan is controlled to remain in a closed state; and / or a prompt message is output to prompt the washing machine door to be opened.

[0075] Here, when the washing machine door is in a closed state, if the centrifugal fan is started to send hot air into the washing tub, the air pressure inside the washing tub will be too high, which may easily cause damage to the washing machine. Therefore, when the washing machine door is in a closed state, the centrifugal fan needs to be controlled to remain in a closed state.

[0076] And / or, when the washing machine door is closed, the user is prompted by voice to open the washing machine door, such as "entering the washing tub drying mode, please open the washing machine door". Alternatively, the signal light installed on the combined washing and drying machine flashes frequently to prompt the user to open the washing machine door, which may also be accompanied by voice prompts. Alternatively, the washing machine door is automatically opened in the form of an electrical signal.

[0077] By adopting the above technical solution, when it is determined that the drying process of the drying tub is in the later stage, the demand for hot air of the dryer is reduced, and the humidity of the hot air in the dryer is also reduced. At this time, the centrifugal fan built into the washing tub is started to send hot air into the washing tub for drying. On the basis of not affecting the working process of the dryer, the residual water in the washing machine is dried, thereby achieving the purpose of full utilization of resources, and at the same time, the problem that the washing machine is prone to breeding bacteria is also solved.

[0078] Based on the above embodiments, the present application also provides a control method for a combined washer-dryer. Figure 3 This is a third flow chart of the control method for a combined washer-dryer in an embodiment of the present application, wherein the combined washer-dryer includes a washing machine and a dryer, the dryer includes a heat source module, the washing machine includes a washing machine air duct and a washing tub, the washing machine air duct includes a centrifugal fan for delivering hot air into the washing tub; wherein the heat source module is connected to the washing tub via the washing machine air duct.

[0079] like Figure 3 As shown, the control method of the combined washer-dryer may specifically include:

[0080] Step 301: Receive a drying instruction from the washing tub.

[0081] Step 302: In response to the drying instruction, determine whether the washing machine door is in an open state; if so, execute step 304; if not, execute step 303.

[0082] Step 303: Control the centrifugal fan to remain in a closed state; and / or output a prompt message to prompt the user to open the washing machine door.

[0083] Step 304: Determine whether the dryer is in working state; if not, execute step 305; if so, execute step 306.

[0084] Step 305: Start the heat source module and start the centrifugal fan.

[0085] Step 306: Determine whether the drying process of the dryer is in the late drying stage; if so, execute step 307; if not, continue to execute step 306 and wait for the drying process to enter the late drying stage.

[0086] Step 307: Start the centrifugal fan.

[0087] Step 308: The hot air generated by the heat source module is sent into the washing tub through the washing machine air duct for drying, and the air in the washing tub is discharged from the washing machine door.

[0088] By adopting the above technical solution, when the dryer is not in working state, the heat source module and the centrifugal fan built into the washing tub are directly started to send hot air into the washing tub for drying; when the dryer is in working state and the drying process is in the later stage, the centrifugal fan built into the washing tub is started to send hot air into the washing tub for drying, so that the residual water in the washing machine can be dried without affecting the working process of the dryer, so as to achieve the purpose of full utilization of resources and solve the problem of bacteria breeding in the washing machine. In addition, the air in the washing tub is discharged from the washing machine door, which solves the problem that the washing machine has no special air outlet and avoids the problem of excessive air pressure inside the washing tub.

Figure 5 As shown, the dryer air path 50 includes an air inlet 51, a drying barrel 52, a first centrifugal fan 53 and an air outlet 54. When the first centrifugal fan 53 is in operation, air is sucked into the air inlet 51, heated by a heater (not shown) to generate hot air, and the hot air is transported to the drying barrel 52 through the dryer air path 50 for drying wet clothes. At the same time, the humidified air is discharged from the dryer from the air outlet 54 to achieve the drying function.

Figure 6 As shown, the air path 60 of the washing machine includes an air inlet 51, a second centrifugal fan 61, a washing tub 62 and a washing machine door 63. When the second centrifugal fan 61 is in operation, air is sucked into the air inlet 51, and the air is heated by a heater (not shown) to generate hot air, and the hot air is transported to the washing tub 62 through the washing machine air path 60 to dry the moisture remaining between the inner tub and the outer tub of the washing tub. At the same time, the humidified air is discharged from the washing tub door 63 to achieve the washing tub drying function and prevent bacteria from growing in the washing machine.

[0093] In order to implement the method of the embodiment of the present application, based on the same inventive concept, the embodiment of the present application also provides a control device for a combined washer-dryer.
