[0043] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0044] In order to reduce the situation that the filter assembly cannot be detected to be blocked in a timely manner in the related art, and the abnormal operation of the clothes dryer is easily caused, the present application provides a clothes dryer and a control method thereof, which will be described below with reference to the drawings.

[0045] Please refer to Figure 1 , Figure 1 The structural schematic diagram of the clothes dryer provided in the embodiments of the present application is shown. The present application provides a clothes dryer 1, which can dry clothes. The clothes dried by the clothes dryer 1 do not need to be aired, and the user can directly wear them. The clothes dryer 1 can have various types. For example, the clothes dryer 1 can be a heat pump type clothes dryer. The heat pump type clothes dryer is composed of a compressor and an evaporator, etc. Heat is circulated in the heat pump assembly, and heat exchange is performed with the clothes in the inner drum, so as to continuously discharge the moisture in the clothes, and dry the clothes. For another example, the clothes dryer 1 can be a condensing type clothes dryer. The condensing type clothes dryer is to heat the air by a heating element, and transmit the air to the inner drum to exchange heat with the clothes, and then condense the exhaust air to continuously discharge the moisture in the clothes, and dry the clothes. Of course, the clothes dryer 1 can also have other types, which will not be listed one by one here. The heat pump type clothes dryer and the condensing type clothes dryer have different working modes, and the embodiments of the present application do not limit the type of the clothes dryer 1. For the convenience of description, the embodiments of the present application take the heat pump type clothes dryer as an example for description.

[0046] It should be noted that the clothes dryer 1 can be in the form of a drum, that is, the shape and internal structure are similar to those of a drum washing machine. The washing method of the drum washing machine is designed by imitating the principle of a club hitting clothes. The drum washing machine is composed of a stainless steel inner drum, a mechanical program controller, a shell protected by phosphating, electrophoresis and spraying, and a plurality of heavy cement blocks for balancing the huge centrifugal force generated during the rotation of the drum to make repeated movements, plus the combined action of washing powder and water to wash the clothes clean. Therefore, the clothes dryer 1 of the present application is also in the form of an inner drum with a lifting rib in the inner drum to drive the clothes to rotate, so as to uniformly dry the clothes.

[0047] For example, please refer to Figure 1 and refer to Figure 2 and Figure 3 , Figure 2A first cutaway structure schematic diagram of a clothes dryer provided by an embodiment of the present application, Figure 3 A structure schematic diagram of a partial A of the clothes dryer is shown. Figure 2 The clothes dryer 1 comprises a cabinet 10, an inner drum 20, a door assembly 30, an air inlet pipe 40, a filter assembly 50, a detection assembly 60, and a controller 70.

[0048] The cabinet 10 is the overall shape structure of the clothes dryer 1. For example, the cabinet 10 can be in the form of a cuboid, a square or a cylinder. The cabinet 10 can also be in a special shape. The cabinet 10 has a containing space 11 and an opening 12 in communication with the containing space 11. The containing space 11 is used to contain components of the clothes dryer 1 such as the inner drum 20, the air inlet pipe 40, the filter assembly 50, etc. The opening 12 is used to provide a space for a user to put clothes in or take clothes out.

[0049] The inner drum 20 is arranged in the containing space 11. The inner drum 20 is used to carry clothes. The inner drum 20 can also be referred to as a drum. The inner drum 20 can rotate under the drive of a motor. When the inner drum 20 rotates, the clothes inside the inner drum 20 can be tumbled to be evenly dried.

[0050] The door assembly 30 is rotatably connected with the cabinet 10 to close or expose the opening 12. It can be understood that the door assembly 30 cooperates with the cabinet 10 to form a complete clothes dryer 1 structure. When it is needed to dry clothes or after the clothes are dried, the door assembly 30 can be opened to expose the opening 12, so that the clothes can be put into the inner drum 20 or taken out of the inner drum 20.

[0051] The air inlet pipe 40 is a transmission channel for sending hot air into the inner drum 20. For a heat pump type clothes dryer, a heat pump assembly can be arranged below the inner drum 20. At this time, the air inlet pipe 40 can be arranged from the heat pump assembly towards the inner drum 20 to send hot air into the inner drum 20. For example, the air inlet pipe 40 has an air outlet 41 arranged towards the inner drum 20.

[0052] In some embodiments, the heat pump assembly can also be arranged above the inner drum. At this time, the air inlet pipe is led from above the inner drum towards the inner drum.

[0053] It should be noted that for a condenser type clothes dryer, the air inlet pipe can be arranged above the inner drum, and a heating element and a fan are arranged in the air inlet pipe. The heating element is used to heat air, and the fan is used to accelerate the flow of hot air into the inner drum.

[0054] The filter assembly 50 is arranged at the air outlet 41. The filter assembly 50 is connected with the air inlet pipe 40, and the filter assembly 50 can cover the air outlet 41. The filter assembly 50 has a filter screen. Air in the air inlet pipe 40 can pass through the filter screen to be sent into the inner drum 20.

[0055] The detection assembly 60 is arranged on the door body assembly 30 and is close to the air outlet 41. The detection assembly 60 is used to detect the temperature and pressure in the inner drum 20.

[0056] The controller 70 is the control center of the clothes dryer 1. The controller 70 can be electrically connected with the detection assembly 60. The controller 70 is used to determine whether the filter assembly 50 is blocked according to the temperature and / or pressure. For example, if the temperature is less than a temperature threshold value and the pressure is greater than or equal to a pressure threshold value, it can be determined that the filter assembly 50 is blocked. Therefore, the hot air in the air inlet pipe 40 cannot be sent into the inner drum 20, which leads to a decrease in the temperature at the air outlet 41. In addition, the blockage also causes the pressure in the inner drum 20 to continuously rise. Therefore, through the changes in the temperature and pressure at the air outlet 41, the blockage of the filter assembly 50 can be known in time to prevent a larger safety accident from occurring.

[0057] In some embodiments, the amount of lint collected in the filter assembly 50 can also be determined by detecting the change in the air speed of the filter assembly 50. The amount of lint can be displayed in real time on the display panel of the clothes dryer 1. When the amount of lint exceeds a threshold value, the user can be reminded to clean the lint.

[0058] In the clothes dryer 1 provided by the embodiments of the present application, the detection assembly 60 is arranged on the door body assembly 30 and is close to the air outlet 41. The detection assembly 60 can detect the temperature and pressure at the filter assembly 50 and the air outlet 41 in the inner drum 20. Compared with arranging the detection assembly at other positions, the changes in the temperature and / or pressure at the filter assembly 50 can be sensed in time. Whether the filter assembly 50 is blocked can be determined according to the change in the parameters at the filter assembly 50 to prevent a larger safety accident from occurring and ensure the normal operation of the clothes dryer 1.

[0059] The door body assembly 30 includes a door bowl 31 and a door cover 32. The door bowl 31 includes a bottom wall 310 and a side wall 312. The side wall 312 is connected to the bottom wall 310 away from the inner drum 20. The bottom wall 310 and the side wall 312 surround to form a groove 314. The detection assembly 60 is arranged on the bottom wall 310. The door cover 32 is connected to the side wall 312 away from the bottom wall 310 and closes the groove 314. Arranging the detection assembly 60 on the bottom wall 310 close to the air outlet 41 can make the detection assembly 60 close to the air outlet 41. In addition, this position is also the intersection of the air outlet 41 and the inner drum 20. The real-time temperature in the inner drum 20 can also be detected to prevent the damage of the clothes caused by the high temperature in the inner drum 20.

[0060] For example, referring to Figures 1 to 3 and referring to Figure 4 and Figure 5 , and Figure 4This is a schematic diagram of a second cross-sectional structure of a clothes dryer provided in an embodiment of this application. Figure 5 for Figure 4 The diagram shows a partial structural schematic of the dryer. The detection component 60 may include a mounting base 61 and a detection unit 62. The mounting base 61 is used to mount the detection component 60. For example, the mounting base 61 may be connected to the bottom wall 310. The mounting base 61 may be cylindrical, with its sidewalls embedded in the bottom wall 310. The side of the mounting base 61 facing the inner drum 20 may be flush with the bottom wall 310, while the side of the mounting base 61 away from the inner drum 20 may protrude from the bottom wall 310. Since the bottom wall 310 is relatively thin, the protrusion of the mounting base 61 from the bottom wall 310 increases the volume of the mounting base 61, thereby facilitating the arrangement of the detection unit 62 and other components.

[0061] Among them, the detection unit 62 can be a component that integrates temperature and pressure detection, that is, an integrated temperature and pressure sensor, which can save the cost of setting up separate temperature and pressure sensors and is convenient to use.

[0062] For example, the detection component 60 also includes a valve 63, which is disposed on the side of the mounting base 61 opposite to the inner cylinder 20. The controller 70 is electrically connected to the valve 63 and is used to control the valve 63 to open when the pressure inside the inner cylinder 20 exceeds a threshold, so as to release part of the pressure inside the inner cylinder 20 into the groove 314 and prevent safety accidents caused by excessive pressure inside the inner cylinder 20.

[0063] For example, the door cover 32 may be provided with a vent hole (not shown in the figure). The vent hole is connected to the groove 314. When the pressure in the inner cylinder 20 exceeds the threshold, the valve 63 of the detection component 60 is opened to release the pressure in the inner cylinder 20 into the groove 314, and then release it to the outside through the vent hole, which can reduce the pressure in the inner cylinder 20.

[0064] It should be noted that the detection component 60 in this embodiment can detect not only the temperature inside the inner cylinder 20, but also the temperature of the door assembly 30. By reusing the detection component 60, the number of sensors can be reduced, thereby reducing the manufacturing cost of the dryer 1.

[0065] For example, the dryer 1 also includes a display panel 80, which is disposed on the housing 10. The display panel 80 is used to display the operating parameters of the dryer 1, such as the operating mode and operating time. The controller 70 is electrically connected to the display panel 80. The controller 70 is also used to calculate the temperature of the door cover 32 based on the temperature inside the inner drum 20, and upload the temperature of the door cover 32 to the display panel 80 for display, so as to provide the user with the temperature of the door cover 32 and prevent the user from being burned when touching the door cover 32 when the temperature is too high.

[0066] For example, the clothes dryer 1 further comprises an alarm (not shown in the figure), which is electrically connected with the controller 70, and the controller 70 is configured to control the alarm to alarm when the temperature of the door cover 32 exceeds a threshold value, so as to remind the user not to touch the door cover 32 at this time, and the user can be prevented from being scalded.

[0067] Wherein, the temperature of the door cover 32 can be calculated according to the temperature detected by the detection assembly 60. For example, the detection assembly 60 can detect the temperature at the door bowl 31, and the temperature of the door cover 32 is calculated by Fourier's law. When the temperature corresponding to the door cover 32 exceeds a set value such as 60℃, a high-temperature alarm can be given through the display panel 80, or an alarm can be given through the alarm to remind the user not to touch the door body assembly 30 to prevent scalding.

[0068] According to Fourier's law, the calculation formula under stable heat conduction conditions is:

[0069] Wherein, Q is the heat conduction rate, λ is the heat conduction coefficient, A is the heat transfer area, t1 and t2 are the temperatures of the heat conduction body such as the door bowl 31 before and after, respectively; b is the thickness of the heat conduction body; Δt=t1-t2, that is, the temperature difference on both sides of the heat conduction body, and R=b / λA is the heat conduction resistance. The actual thermal resistance of each component of the door body assembly 30 is calculated by experimentally measuring the surface temperature of each component of the door body assembly 30, the heat conduction coefficient of each component, and the heat transfer surface and wall thickness. The temperature of the door cover 32 can be calculated by detecting the temperature inside the door bowl 31 and the above formula.

[0070] In the clothes dryer 1 provided by the embodiment of the present application, the detection assembly 60 is arranged on the door body assembly 30 and close to the air outlet 41, and the detection assembly 60 can detect the temperature and pressure at the filter assembly 50 and the air outlet 41 in the inner drum 20. Compared with arranging the detection assembly at other positions, the detection assembly 60 can timely sense the change of the temperature and / or pressure at the filter assembly 50, and determine whether the filter assembly 50 is blocked according to the change of the parameters at the filter assembly 50, so as to prevent a larger safety accident from occurring and ensure the normal operation of the clothes dryer 1. Moreover, the detection assembly 60 can be reused to detect the temperature of the door cover 32, the number of sensors is reduced, and the manufacturing cost of the clothes dryer 1 can be reduced.

[0071] The following will be described from the perspective of the control method of the clothes dryer.

[0072] Please refer to Figures 1 to 5 and Figure 6 shown, Figure 6 The first flowchart of the control method of the clothes dryer provided by the embodiment of the present application. The structural components of the clothes dryer can refer to Figures 1 to 5 and the above description, which will not be described here. The embodiment of the present application also provides a control method of a clothes dryer, comprising:

[0073] 101. The temperature and pressure inside the inner cylinder are obtained by a detection component installed on the door assembly and near the air outlet of the air inlet pipe.

[0074] In related technologies, the inability to detect clogged filter components in a timely manner can easily lead to abnormal operation of the dryer.

[0075] To reduce the occurrence of the above situations, in this embodiment of the application, the detection component is set on the door assembly and near the air outlet of the air inlet pipe. The detection component is used to detect the temperature and pressure inside the inner cylinder, that is, the temperature and pressure of the inner cylinder near the air outlet. Since the filter component is set at the air outlet, the temperature and pressure changes at the air outlet can reflect the clogging status of the filter component, so the clogging status of the filter component can be known in a timely manner.

[0076] The door assembly includes a door cup and a door cover. The door cup includes a bottom wall and a side wall. The side wall is connected to the bottom wall on the side facing away from the inner tub, and the bottom wall and side wall form a groove. A detection component is disposed on the bottom wall. The door cover is connected to the end of the side wall facing away from the bottom wall and seals the groove. Placing the detection component on the bottom wall near the air outlet ensures a close proximity between the component and the outlet. This location also coincides with the junction of the air outlet and the inner tub, allowing for real-time temperature detection within the inner tub and preventing damage to clothing due to excessively high temperatures.

[0077] The detection component can be a sensor that integrates temperature and pressure, i.e., a temperature and pressure integrated sensor. This can save the cost of setting up separate temperature and pressure sensors and is also convenient to use.

[0078] 102. Determine whether the filter assembly is clogged based on temperature and / or pressure.

[0079] The filter assembly is used to determine whether it is clogged based on the temperature and pressure detected by the detection component. The detection component can detect both temperature and pressure parameters simultaneously, but in use, the filter assembly can be clogged based on temperature, pressure, or both.

[0080] In some embodiments, the clogging of the filter assembly can be determined based on temperature or pressure. For example, when the temperature is below a threshold, it indicates that hot air in the inlet duct is not being delivered to the inner drum, thus causing a temperature drop. In other words, the clogging of the filter assembly can be determined based on the temperature near the filter assembly and the air outlet. Similarly, when the pressure exceeds a threshold, it indicates that airflow in the inner drum is restricted. For heat pump dryers, a clogged filter assembly restricts heat circulation, causing the pressure inside the inner drum to rise continuously. Therefore, the clogging of the filter assembly can also be determined based on the pressure inside the inner drum.

[0081] For example, if the temperature is lower than a threshold value and the pressure exceeds a pressure threshold value, it is determined that the filter assembly is blocked. That is, the temperature and pressure are used to determine the blockage of the filter assembly, which can improve the accuracy of the determination and reduce inaccurate detection caused by a single parameter.

[0082] In some embodiments, the amount of lint collected in the filter assembly can also be determined by detecting the change in air speed of the filter assembly, and the amount of lint can be displayed in real time on the display panel of the clothes dryer. When the amount of lint exceeds a threshold value, the user can be reminded to clean the lint.

[0083] In the control method of the clothes dryer provided in the embodiments of the present application, the detection assembly is arranged on the door body assembly and close to the air outlet. The detection assembly can detect the temperature and pressure at the filter assembly and the air outlet in the inner drum. Compared with arranging the detection assembly at other positions, the change in temperature and / or pressure at the filter assembly can be sensed in time, and whether the filter assembly is blocked can be determined according to the change in parameters at the filter assembly, so that a larger safety accident can be prevented and the normal operation of the clothes dryer can be ensured.

[0084] Please refer to Figures 1 to 6 and Figure 7 shown, Figure 7 the second flowchart of the control method of the clothes dryer provided in the embodiments of the present application. The structural components of the clothes dryer can be referred to Figures 1 to 5 and the above description, which will not be described here. The embodiments of the present application also provide a control method of a clothes dryer, comprising:

[0085] 201. Obtain the temperature of the door cover through the detection assembly arranged on the door bowl.

[0086] The detection assembly of the embodiments of the present application can not only detect the temperature in the inner drum, but also detect the temperature of the door body assembly. The detection assembly is reused, the arrangement of the sensor is reduced, and the manufacturing cost of the clothes dryer can be reduced.

[0087] The temperature of the door cover can be calculated according to the temperature detected by the detection assembly. For example, the detection assembly can detect the temperature at the door bowl, calculate the temperature of the door cover according to Fourier's law, and when the temperature corresponding to the door cover exceeds a set value such as 60℃, a high-temperature alarm can be given through the display panel, or an alarm can be given through an alarm to remind the user not to touch the door body assembly to prevent burns.

[0088] According to Fourier's law, the calculation formula under stable heat conduction conditions is: Q = λA(t1-t2) / b = Δt / R.

[0089] Wherein, Q is the heat transfer rate, λ is the thermal conductivity, A is the heat transfer area, t1, t2 are the temperatures of the heat conduction body such as the door bowl before and after respectively; b is the thickness of the heat conduction body; Δt = t1-t2, that is, the temperature difference of the two sides of the heat conduction body, R = b / λA, is the thermal resistance. By experimentally measuring the surface temperature of each component of the door body assembly, the thermal conductivity of each component, and the heat transfer surface and wall thickness, the actual thermal resistance of each component of the door body assembly is calculated, and by detecting the temperature inside the door bowl and the above formula, the temperature of the door cover can be calculated.

[0090] The temperature of the door cover can be displayed by the display panel for the user to view.

[0091] 202. When the temperature of the door cover exceeds the set value, a reminder of the high temperature of the door cover is given.

[0092] When the temperature of the door cover exceeds the set value such as 60℃, a reminder of the high temperature of the door cover can be given, such as high temperature alarm can be given through the display panel, or alarm can be given through an independently set alarm, reminding the user not to touch the door cover to prevent burns.

[0093] In the control method of the clothes dryer provided in the embodiments of the present application, by multiplexing the detection assembly arranged on the door body assembly, not only the temperature and pressure inside the inner drum can be detected, but also a reminder and pressure relief can be given when the threshold value is exceeded to prevent safety accidents; the temperature of the door cover can also be detected, and a reminder can be given when the temperature of the door cover exceeds the set value to prevent the temperature of the door cover from being too high to burn the user, and a safety reminder can be given.

[0094] The clothes dryer 1 can also include a processor with one or more processing cores, a memory with one or more computer readable storage media, and a computer program stored on the memory and executable on the processor. The processor is electrically connected to the memory. Those skilled in the art can understand that the structure of the clothes dryer 1 shown in the figure does not constitute a limitation on the clothes dryer, and can include more or fewer components than shown, or combine certain components, or different component arrangements.

[0095] The processor is the control center of the clothes dryer, and connects all parts of the clothes dryer through various interfaces and lines. For example, the processor can be electrically connected to the detection assembly, execute various functions of the clothes dryer and process data by running or loading software programs and / or modules stored in the memory and calling data stored in the memory, thereby overall monitoring the clothes dryer.

[0096] In the embodiments of the present application, the processor in the clothes dryer will load the instructions corresponding to the processes of one or more application programs into the memory, and run the application programs stored in the memory by the processor, thereby realizing various functions:

[0097] acquire the temperature and the pressure in the inner cylinder through a detection assembly arranged on the door body assembly and close to the air outlet of the air inlet pipe;

[0098] determine whether the filter assembly is blocked according to the temperature and / or the pressure.

[0099] The specific implementation of each operation can refer to the foregoing embodiments, which will not be described here again.

[0100] Those skilled in the art can understand that all or part of the steps in the various methods of the foregoing embodiments can be completed by instructions, or by relevant hardware controlled by the instructions, which can be stored in a computer readable storage medium and loaded and executed by a processor.

[0101] To this end, an embodiment of the present application provides a computer readable storage medium, which stores a plurality of computer programs capable of being loaded by a processor to execute the steps in the control method of the clothes dryer provided by the embodiment of the present application.

[0102] The storage medium can include a read only memory (ROM), a random access memory (RAM), a magnetic disk or an optical disk, and various media capable of storing program codes.

[0103] Since the computer programs stored in the storage medium can execute the steps in the control method of the clothes dryer provided by the embodiment of the present application, the beneficial effects of any of the control methods of the clothes dryer provided by the embodiment of the present application can be achieved, which will be described in detail in the foregoing embodiments and will not be described here again.
