[0002] The popularity of dryers has brought great convenience to people's lives. The heat pump dryer includes a drying barrel, a drying duct, and a heat pump drying system and a fan arranged in the drying duct. During operation, the fan is driven to form an air circulation between the drying barrel and the drying duct, and the hot air takes away the moisture in the clothes to dry the clothes. When the drying barrel and the fan rotate at high speed, negative pressure will be generated in the drying duct, among which the negative pressure at the base duct and the bottom of the condenser and evaporator is the most obvious. However, the generation of negative pressure will cause the condensed water to fail to flow out normally into the water collection box and be discharged by the drainage pump, which reduces the drying efficiency of the dryer and prolongs the drying time of the clothes, which is not conducive to providing users with a good experience.

Therefore, the present application 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 the present application.

[0047] The present application provides a control method for a clothes dryer, which may be a clothes dryer having only a drying function or a clothes washer-dryer having both washing and drying functions. Figure 1 , Figure 1 This is a flow chart of a control method for a clothes dryer provided in an embodiment of the present application. The clothes dryer includes a drainage pump and a clothes drying barrel. It should be noted that the drainage pumps described in the present application all refer to drainage pumps used to discharge condensed water in the clothes dryer. The control method includes the following steps S101-S102:

[0048] Step S101: in response to an execution instruction of a clothes drying program, obtaining operation information of the current clothes drying barrel, the operation information including at least one of a direction information, a rotation speed information and an operation duration information;

[0049] It should be noted that the dryer is pre-set with several different drying programs, and the drying program usually includes a series of preset steps and parameters, which are intended to optimize the drying effect according to different types of clothing and user needs. The drying program can be manually input and selected by the user, or it can be intelligently selected by the dryer according to the actual clothes to be processed. Exemplarily, the dryer can be pre-set with a quick drying program, a standard drying program, a wool / silk drying program, an air circulation program, an energy-saving drying program, a deodorization program, etc. Among them, for example, the standard drying program is suitable for most clothes including cotton, linen, chemical fiber, etc. The program duration is usually 1 to 1.5 hours, and the temperature is moderate, balancing the drying effect and clothing protection; for example, the quick drying program is suitable for thinner or high-temperature resistant clothes such as towels, sheets, etc., and the program duration is shorter, usually between 30 minutes and 1 hour, and the drying temperature is higher to quickly remove moisture; for example, the wool / silk drying program has the characteristics of long duration and low temperature, and is usually accompanied by gentle stirring or flipping of the clothes to avoid entanglement of the clothes.

[0050] The steering information includes the current steering state of the dryer, such as whether it is in a forward state or a reverse state. It should be noted that during the drying process, the dryer continuously rotates the dryer forward to turn the clothes in the dryer, so as to achieve uniform heating of the clothes and improve the drying efficiency. In addition, by reversing the dryer, the position of the clothes in the dryer can be balanced, the clothes can be prevented from sticking in the dryer, and the clothes can be further heated evenly. The increase in the reversal time of the dryer will extend the total duration of the drying program and affect the drying efficiency. For different programs, due to different drying requirements, the program may or may not include steps that require the dryer to be reversed.

[0051] The rotation speed information includes the current rotation speed of the drying tub. It should be noted that the dryer also includes a drive motor, the output end of which is connected to the drying tub for driving the drying tub to rotate. Based on this, the rotation speed of the drying tub is related to the rotation speed of the drive motor, and the direction of the drying tub is also related to the direction of the drive motor.

[0052] The operation duration information includes the rotation duration of the clothes drying tub, such as the forward rotation duration, the reverse rotation duration, the stationary duration and other time parameters.

[0053] It should be noted that by obtaining the operating information of the dryer, the current rotation speed of the dryer can be determined, and then the current negative pressure in the drying duct can be determined, that is, the greater the rotation speed of the dryer, the greater the negative pressure in the drying duct.

[0054] The operation information includes at least one of the steering information, speed information and operation duration information, indicating that the operation information can be any one of the steering information, speed information and operation duration information, or a combination of any two or three of the steering information, speed information and operation duration information.

[0055] Step S102: Control the drain pump to turn on and off according to the operation information.

[0056] It can be understood that the operation information can reflect the current negative pressure situation in the drying duct of the clothes dryer, and the drain pump is turned on and off according to the operation information, that is, the drain pump is turned on and off according to the current negative pressure situation in the drying duct. In this way, the drain pump opening time is intelligently selected according to the negative pressure situation, which can reduce the impact of the negative pressure in the drying duct on the normal discharge of condensed water and avoid affecting the drying efficiency.

[0057] The control method of the dryer provided in the embodiment of the present application intelligently controls the opening time of the drain pump according to the operating information of the drying barrel, thereby avoiding opening the drain when the negative pressure in the drying air duct is large, so that the condensed water can flow into the water storage box normally and be discharged by the drain pump, thereby preventing the drying efficiency from being affected due to the difficulty in discharging the condensed water in time.

[0058] Further, regarding how to control the drain pump to be turned on and off according to the operation information, the embodiment of the present application provides a more specific embodiment, and controlling the drain pump to be turned on and off according to the operation information includes:

[0059] If some clothes barrels are in reverse state, the drain pump is turned on and the drain pump is turned off after the clothes barrel stops reverse;

[0060] When some clothes drying tubs are in the forward rotation state, the drain pump is controlled to be turned on intermittently, and the rotation speed of the clothes drying tub is reduced during the period when the drain pump is turned on.

[0061] It should be noted that some drying programs of the dryer have a reversing step, which is usually interspersed in the forward rotation step, or set before or after the forward rotation step. In different programs, the position and execution duration of the reversing step are different, which can be set by the designer according to actual needs. The dryer barrel reverses to balance the position of the clothes in the dryer barrel or to break up the clothes. Since the speed of the dryer barrel is low when it is reversed, it will not cause a large negative pressure in the drying air duct. In this way, the condensed water can flow smoothly into the water storage box when the negative pressure is very small. At this time, by opening the drain pump to discharge the condensed water in the water storage box, the condensed water can be prevented from affecting the drying efficiency.

[0062] The dryer may also have a drying program that does not include a reversing step. When executing such a drying program, the drying barrel will maintain high-speed forward rotation for a long time, for example, maintaining forward rotation for 1 hour or even longer. When the drying barrel rotates forward at high speed, a large negative pressure will be generated in the drying air duct, especially at the bottom of the condenser and evaporator. The negative pressure is most obvious, which will cause the condensed water to be unable to be discharged from the dryer under the action of negative pressure, thereby affecting the drying efficiency. In this application, on the one hand, the drain pump is intermittently turned on to discharge the condensed water in time. On the other hand, the rotation speed of the drying barrel is reduced while the drain pump is turned on, which can reduce the negative pressure in the drying duct, so that the condensed water can flow smoothly into the water storage box and be discharged in time by the drain pump. In this way, the problem that the condensed water cannot be discharged from the dryer under the action of negative pressure and affects the drying efficiency can be avoided.

[0063] Optionally, controlling the drain pump to be turned on intermittently and reducing the rotation speed of the drying tub during the period when the drain pump is turned on includes:

[0064] Control the drainage pump to start for a second preset time period every first preset time period;

[0065] When the drain pump is turned on, the rotation speed of the clothes drying tub is reduced from the first preset rotation speed to the second preset rotation speed, and before the drain pump is turned off, the rotation speed of the clothes drying tub is controlled to increase from the second preset rotation speed to the first preset rotation speed.

[0066] Among them, the first preset time length and the second preset time length can be determined by the designer according to the capacity of the water storage box of the dryer. The larger the capacity of the water storage box, the longer the first preset time length and the second preset time length can be. Exemplarily, controlling the drain pump to be turned on intermittently is to control the drain pump to be turned on for 20 seconds every 10 minutes. The first preset speed is the speed of the drying barrel when the dryer is drying normally. The second preset speed can be determined by the designer according to the specific shape parameters of the drying air duct, so that when the speed of the drying barrel is reduced to the second preset speed, the condensed water will at least not be sucked back due to excessive negative pressure in the drying air duct.

[0067] It can be understood that when the drain pump is turned on, the rotation speed of the dryer barrel is initially reduced from the first preset speed to the second preset speed, and before turning off the drain pump, the rotation speed of the dryer barrel is controlled to increase from the second preset speed to the first preset speed, that is, in the process of controlling the speed of the dryer barrel to increase and decrease, the drain pump remains on, so that the residual water in the water storage box can be drained as cleanly as possible.

[0068] In some embodiments, turning on the drain pump until the clothes drying tub stops reversing and then turning off the drain pump comprises:

[0069] Turn on the drain pump;

[0070] The drain pump is controlled to be turned off after a third preset time delay after the clothes drying tub stops reversing.

[0071] It can be understood that by delaying the third preset time to turn off the drain pump after the clothes drying tub stops reversing, the residual water in the water storage box can be drained as cleanly as possible.

[0072] In some embodiments, controlling the drain pump to be turned on and off according to the operation information further includes:

[0073] When the direction information of the clothes drying barrel is switched to the forward state, the drainage pump is controlled to start, and the first timing is started;

[0074] When the first timing duration reaches a fourth preset duration, the drainage pump is controlled to be turned off.

[0075] It should be noted that when the steering information of the clothes drying barrel is switched to the forward state, the drain pump is turned on, which means that the drain pump is controlled to be turned on when the clothes drying barrel is just switched from the reverse state or the stationary state to the forward state. After the steering information of the clothes drying barrel is switched to the forward state, the speed of the clothes drying barrel gradually increases from zero to the set speed. During the process of increasing the speed, a period of time when the speed of the clothes drying barrel is relatively low will be experienced. The fourth preset speed can be determined by the designer according to the actual situation. Before the first timing duration reaches the fourth preset duration, the speed of the clothes drying barrel is in a relatively low state. Exemplarily, the fourth preset duration is 5s. In this way, the negative pressure in the drying channel of the clothes drying barrel is relatively small during the period when the speed of the clothes drying barrel is relatively low. By turning on the drain pump, the condensed water can flow smoothly into the water storage box and be discharged in time by the drain pump, which can avoid the problem that the condensed water cannot be discharged from the clothes drying machine under the action of negative pressure and affects the drying efficiency. Optionally, the drain pump can also be turned on before the steering information of the clothes drying barrel is switched to the forward state.

[0076] In some embodiments, the control method of the clothes dryer further includes:

[0077] Identify the current operation stage of the dryer;

[0078] If some washing machines are in the condensing stage, the drain pump is controlled to start.

[0079] The condensation phase of a dryer is a critical step in the clothes drying process. It involves converting the water in the clothes from a gaseous state to a liquid state and removing it from the clothes. During the condensation phase, the speed of the dryer drum is reduced. The dryer heats the air in the dryer drum through a heating element such as a heating wire or a heat pump. When the hot air is blown over the clothes, it takes away the water vapor evaporated from the clothes. This hot air containing water vapor is then sent to the condenser. In the condenser, the hot air flows over a cooled surface. Since the temperature of the condenser is lower than the temperature of the water vapor in the air, the water vapor will lose heat and condense into small water droplets. The condensed water droplets will drip along the surface of the condenser, flow into the water storage box, and finally drain out of the dryer through the drain pump. During the condensation phase, the drain pump is opened as much as possible to drain as much condensed water as possible.

[0080] In some embodiments, the clothes dryer further includes a water storage box, the water storage box is used to receive condensed water, a drainage pump is disposed in the water storage box, and is used to drain water in the water storage box out of the clothes dryer, and the control method of the clothes dryer further includes:

[0081] Get the water level information in the water storage box;

[0082] If the current water level of the water storage box is greater than the preset water level, the drainage pump is controlled to start for the fifth preset time period.

[0083] When the current water level of the water storage box is greater than the preset water level, the drainage pump is controlled to start, so as to prevent the water stored in the water storage box from overflowing due to excessive water.

[0084] The control method of the dryer provided in the embodiment of the present application intelligently controls the opening time of the drain pump according to the operating information of the drying barrel, thereby avoiding opening the drain when the negative pressure in the drying air duct is large, so that the condensed water can flow into the water storage box normally and be discharged by the drain pump, thereby preventing the drying efficiency from being affected due to the difficulty in discharging the condensed water in time.

[0085] The present application also provides a control device for a clothes dryer.

[0086] The acquisition module 210 is used to respond to the execution instruction of the drying program to obtain the operation information of the drying barrel, and the operation information includes at least one of the steering information, the speed information and the operation time information; the control module 220 is used to control the drainage pump to open and close according to the operation information.

[0087] The control device 200 of the dryer provided in the embodiment of the present application intelligently controls the opening time of the drain pump according to the operating information of the drying barrel, thereby avoiding opening the drain when the negative pressure in the drying air duct is large, so that the condensed water can flow into the water storage box normally and be discharged by the drain pump, thereby preventing the drying efficiency from being affected by the difficulty in discharging the condensed water in time.

[0089] Among them, the controller 330 is connected to the drainage pump 310 and the drying barrel 320, and is used to: respond to the execution instructions of the drying program, obtain the operation information of the drying barrel 320, the operation information including at least one of the steering information, speed information and operation time information; control the drainage pump 310 to open and close according to the operation information.

[0090] The dryer 300 provided in the embodiment of the present application can intelligently control the opening time of the drain pump 310 according to the operating information of the drying barrel 320, so as to avoid opening the drainage when the negative pressure in the drying air duct is large, so that the condensed water can flow into the water storage box normally and be discharged by the drain pump 310, thereby preventing the drying efficiency from being affected by the difficulty in discharging the condensed water in time.
