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 those skilled in the art without creative work are within the scope of protection of the present invention.

[0053] In this application, the word "exemplary" is used to mean "serving as an example, illustration, or illustration." Any embodiment described in this application as "exemplary" is not necessarily to be construed as being preferred or advantageous over other embodiments. The following description is given to enable any person skilled in the art to implement and use the invention. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the invention can be implemented without using these specific details. In other instances, well-known structures and processes are not elaborated in detail to avoid obscuring the description of the invention with unnecessary details. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.

[0054] The embodiments of the present application provide a clothes dryer and a control method, device and computer-readable storage medium thereof, which are described in detail below.

[0055] Reference Figure 1 As shown, the clothes dryer includes a storage box 40 and a strain sensor 50 disposed at the bottom of the storage box 40. The clothes dryer also includes a box body 80, a drain pump 60, an inner drum 70 and a drain pipe 90. The inner drum 70 is rotatably disposed in the box body 80. The storage box 40 is configured to be movably disposed on the box body 80 or detachably disposed on the box body 80. When the clothes dryer is working, the water in the inner drum 70 is taken away by the high-temperature gas, and the gas containing water vapor condenses into water under the condensation effect, and is stored in the water tank of the clothes dryer; the drain pump 60 pumps the water in the water tank (located at the bottom of the clothes dryer, not shown in the example) to the storage box 40 located at the top of the clothes dryer through the drain pipe 90; the user cleans the water in the storage box 40.

[0056] In the prior art, a water level detector is provided in the water tank. When the water level detector detects that the water level reaches a preset water level, the drainage pump starts to flush the water in the water tank into the storage box. However, there is still a risk of overflow in the storage box. Therefore, the prior art adopts an overflow pipe to discharge the water back into the water tank. Then, when the water level value detected by the water level detector in the water tank exceeds another water level, an alarm is started to prompt that the water in the storage box can be cleaned. In the prior art, the water level detector detects the water level in the water tank to indirectly detect the water in the storage box. The detection is not timely and accurate (for example, when the drainage pump fails). To this end, the embodiment of the present application provides a control method for a clothes dryer to solve the technical problems existing in the prior art.

[0057] The control method of the clothes dryer provided in the embodiment of the present application is executed by a controller disposed in the clothes dryer. The controller is connected to the strain sensor signal, for example, the two can be connected through a signal line.

[0058] like Figure 2 FIG. 1 is a flow chart of an embodiment of a control method for a clothes dryer according to an embodiment of the present application. The control method for a clothes dryer includes:

[0059] S100, obtaining a strain signal of the strain sensor;

[0060] S200, determining water level information in the storage box according to the strain signal;

[0061] S300: Control the working state of the clothes dryer according to the water level information.

[0062] In the technical solution of the embodiment of the present application, a strain sensor is arranged at the bottom of the storage box. When the water level in the storage box changes, the pressure felt by the strain sensor will change, thereby generating different strain signals; based on the strain signal, the water level information in the storage box is determined; the working state of the dryer is controlled by the water level information; this method does not rely on a water level detector arranged in a water tank to indirectly detect the water level information in the storage box, but can timely and accurately detect the water level information in the storage box, thereby timely and accurately controlling the working state of the dryer.

[0063] In some embodiments, when condensed water enters the storage box, the pressure received by the strain gauge changes, and the strain signal fed back to the controller will be different. The pressure received by the strain gauge depends on the amount of liquid collected in the storage box, and the feedback signal is different for different pressures. When water enters the storage box, taking the resistive strain sensor as an example, the resistive strain sensor will be subjected to water pressure, and the resistive strain gauge will undergo mechanical deformation due to the pressure, and its resistance value will also change accordingly. The pressure received can be calculated by calculating the change in its resistance value, thereby obtaining the water level information in the water box.

[0064] In some embodiments, the resistance strain sensor is a resistance sensor with a resistance strain gauge as a conversion element. The resistance strain sensor is composed of an elastic sensitive element, a resistance strain gauge, a compensation resistor and a housing, and can be designed into a variety of structural forms according to specific measurement requirements. The elastic sensitive element is deformed by the measured force, and the resistance strain gauge attached to it is deformed together. The resistance strain gauge then converts the deformation into a change in resistance value, so that various physical quantities such as pressure can be measured;

[0065] According to the formula ΔR / R=Ks*ε, ΔR / R is the rate of change of resistance, Ks is the sensitivity coefficient of the material, its physical meaning is the rate of change of resistance per unit strain, ε is the strain at the measuring point, and ε is proportional to the magnitude of the pressure; that is, the higher the water level in the storage box, the greater the pressure it generates, the greater the strain, and the greater the rate of change of resistance.

[0066] Compared with the prior art, the clothes dryer provided by the present application does not need to be provided with an overflow pipe, and the water level information in the storage box is not indirectly obtained through the water level detector in the water tank. Moreover, in the prior art, the water level information detected by the water level detector in the water tank is only used to control the start and stop of the drainage pump; while in the technical solution of the present application, the water level information in the storage box is obtained by arranging a strain sensor outside the storage box, thereby controlling the working state of the clothes dryer and timely preventing the water in the storage box from overflowing to the outside; and the strain sensor is arranged outside the storage box, and then no water level detection instrument is arranged in the storage box, which saves space for arranging the water level detection instrument and increases the capacity of the storage box.

[0067] like Figure 3 As shown, as an optional implementation of the above embodiment, determining the water level information in the storage box according to the strain signal includes:

[0068] S210, determining weight information of the storage box according to the strain signal;

[0069] S220: Determine water level information in the storage box according to the weight information.

[0070] In the embodiment, since the strain signal is provided at the bottom of the storage box, the weight of the storage box and the water inside the storage box can be directly reflected by the strain signal; thus, the weight information of the storage box is determined by the strain signal; and then the water level information inside the storage box is determined by the weight information.

[0071] It should be noted that the density of condensed water is fixed, and the weight of the storage box in a waterless state is also fixed; therefore, the weight information determined according to the strain signal can be used to determine the weight of the water in the storage box, and then the volume of the water (a type of water level information) can be calculated; the space inside the storage box is also fixed, so based on the calculation of the volume of water, the water level value in the storage box (another type of water level information) can also be calculated.

[0072] like Figure 4 As shown, as an optional implementation of the above embodiment, the water level information includes a water level value; and controlling the working state of the clothes dryer according to the water level information includes:

[0073] S310: If the water level value exceeds a preset threshold, the clothes dryer is controlled to be in a suspended drying working state and a prompt message is issued.

[0074] In an embodiment, when the water level value exceeds a preset threshold, there is a risk of overflowing the water in the storage box, and thus the dryer is controlled to be in a suspended drying state to avoid further generation of condensed water and causing overflow of the storage box; and a prompt message is issued to remind the user to clean the condensed water in the storage box as soon as possible.

[0075] In some other embodiments, controlling the working state of the clothes dryer according to the water level information includes:

[0076] If the water level exceeds a first preset value, the clothes dryer is controlled to operate at reduced power and a prompt message is issued;

[0077] If the water level exceeds a second preset value, the clothes dryer is controlled to be in a suspended drying state and a prompt message is issued. The second preset value is greater than the first preset value.

[0078] That is, in this embodiment, the second preset value is equal to the preset threshold value; and after the water level exceeds the first preset value, the power of the clothes dryer is reduced to reduce the speed of condensed water generation, and a prompt message is issued at this time to prompt the user to deal with the condensed water as soon as possible. If the water in the storage box is treated before the water level of the condensed water is less than the second preset value, the clothes dryer does not enter the working state of suspending drying, but can quickly increase the power again to continue running, thereby improving the drying efficiency.

[0079] like Figure 5 As shown, as an optional implementation of the above embodiment, controlling the working state of the clothes dryer according to the water level information includes:

[0080] S321, determining a ratio of the volume of water in the storage box to the storage volume of the storage box according to the water level information;

[0081] S322: Control the clothes dryer to display the ratio and / or the volume of water in the storage box.

[0082] In an embodiment, the volume of water in the storage box can be determined based on the water level information, and then the ratio of the volume of water in the storage box to the storage box's capacity can be determined; by displaying the ratio and / or the volume of water in the storage box on the dryer, the user can be prompted in real time to clean the water in the storage box.

[0083] In an embodiment, the clothes dryer is provided with a display screen. The ratio and / or the volume of water in the storage box may be displayed on the display screen in the form of a picture, text, or a combination of pictures and text (for example, an icon showing the water level value in the storage box is displayed on the display screen).

[0084] like Figure 6 As shown, as an optional implementation of the above embodiment, controlling the working state of the clothes dryer according to the water level information includes:

[0085] S331, in response to a clothes drying operation instruction of the clothes dryer, acquiring initial humidity information of a load in the clothes dryer;

[0086] S332, determining an expected output of condensed water according to the initial humidity information;

[0087] S333: Control the working state of the dryer according to the estimated output and the water level information.

[0088] In this embodiment, when the clothes dryer starts to execute the clothes drying work instruction, the initial humidity information of the load in the clothes dryer is obtained, and the expected output of condensed water is determined according to the initial humidity information. Then, according to the expected output and water level information, the working state of the clothes dryer is controlled to avoid overflow of the storage box during the clothes drying process.

[0089] In an embodiment, when the load is dried in the clothes dryer, condensed water is generated. The amount of condensed water is highly correlated with the initial humidity information of the load. The expected output of condensed water can be determined by the initial humidity information. Further, the expected output of condensed water can be determined by the weight of the load and the initial humidity information.

[0090] like Figure 7 As shown, as an optional implementation of the above embodiment, the water level information includes a water level value, and controlling the working state of the dryer according to the expected output and the water level information includes:

[0091] S3331, determining whether the storage box can completely accommodate the condensed water according to the estimated output, the water level value, and the accommodation volume of the storage box;

[0092] S3332: If yes, control the working state of the clothes dryer to a continuous drying state;

[0093] S3333: If not, control the dryer to send a prompt message.

[0094] In the embodiment, the remaining capacity of the storage box can be determined based on the water level value and the storage box storage volume, and then by comparing the expected output and the remaining capacity, it can be determined whether the remaining capacity of the storage box can completely accommodate the condensed water. If it can, the working state of the dryer is controlled to be a continuous drying state until the drying program ends; if it cannot, a prompt message is issued to prompt the user to clean the storage box in time during the drying process, so as to reduce the number of starts and stops of the dryer, which is conducive to improving efficiency and energy saving.

[0095] like Figure 8 As shown, as an optional implementation of the above embodiment, if not, controlling the dry prompt to issue a prompt message includes:

[0096] S3333a, determining the remaining capacity of the storage box according to the water level value and the storage volume of the storage box;

[0097] S3333b, determining, based on the remaining capacity and the initial humidity information, a target humidity value to which the humidity of the load can be reduced at most when the water level in the storage box is at the water level value;

[0098] S3333c, obtaining an actual humidity value of the load;

[0099] S3333d, before the actual humidity value is greater than the target humidity value, controlling the clothes dryer to issue a prompt message;

[0100] like Fig.10 As shown, the control method further includes: S340, when the actual humidity value decreases to the target humidity value, controlling the working state of the dryer to a suspended drying state.

[0101] In this embodiment, the remaining capacity of the storage box indicates how much condensed water can still be stored; accordingly, according to the initial humidity information and the remaining capacity, it can be calculated that when the water level in the storage box is at the water level value, the humidity of the load can be reduced to the target humidity value at most; when the humidity is reduced from the initial humidity information to the target humidity value, the superposition of the generated condensed water and the current water level value is close to or the same as the remaining capacity; therefore, when the water level in the storage box is at the water level value, the dryer can reduce the load from the initial humidity information to the target humidity value at most, thereby avoiding water leakage in the storage box of the dryer. In an embodiment, during the drying process, the actual humidity value of the load is obtained in real time or periodically, and before the actual humidity value is greater than the target humidity value, the dryer is controlled to issue a prompt message, thereby prompting the user to clean the storage box before the water in the storage box is full, so that the dryer can be in a continuous drying operation state.

[0102] Furthermore, if the user may not clean the water in the storage box in time when the dryer issues a reminder message, then when the actual humidity value drops to the target humidity value, the working state of the dryer is controlled to be a suspended drying state to avoid water overflow from the storage box, and a reminder message is also issued to remind the user to clean the storage box in time.

[0103] In the technical solution of the embodiment of the present application, the prompt information can be a flashing light and / or a voice prompt and / or a text prompt on the dryer, or the dryer can send the prompt information to a customer terminal or APP connected to the network with the dryer.
