Description

Technical Field

[0001] The present application relates to the technical field of clothing processing, and in particular to a clothing processing device and a control method for the clothing processing device. Background Art

[0002] With technological advancements, clothes drying devices are becoming increasingly popular. Currently, clothes drying devices often use a single drive unit to simultaneously drive both the fan and the drum. When the drum speed needs to be increased, the fan must also be driven, causing the fan speed to increase, even if the fan speed does not need to be increased. This results in excessively high overall power consumption by the drive unit, preventing the drive unit from exceeding the upper limit of the drum speed while maintaining a constant output power.

[0003] Therefore, how to significantly increase the upper limit of the drum rotation speed while maintaining a constant output power of the driving device is a problem that urgently needs to be solved. Summary of the Invention

[0004] The present application aims to solve the above-mentioned problems and other problems.

[0005] The present application also aims to reduce the operating power of the fan when the fan speed is constant.

[0006] Another object of the present application is to provide a clothing processing device provided with a wind shield to control the air flow passing through the fan.

[0007] Another object of the present application is to provide a clothes processing device that can consume lower power when the fan speed is determined.

[0008] The present application also aims to provide a clothing processing device that increases the drum speed and the fan speed when the output power of the driving device is determined.

[0009] The present application also aims to reduce the working efficiency of the fan by reducing the air flow through the fan, thereby reducing the output power required for the drive device.

[0010] 14. The laundry machine of claim 13, wherein the drum is provided with a drying chamber for drying clothes, the drying chamber being connected to the air inlet component and the air outlet component, respectively; a fan is provided in the machine body, the fan being used to drive the air in the drying duct to flow from the air inlet component to the air outlet component, a heating device is provided in the machine body, the heating device is used to heat the air in the drying duct, a driving device is provided in the machine body, and is used to drive the drum and the fan to rotate, a condensing device is provided in the machine body, and is used to condense the air entering the drying duct, a wind shield is provided in the machine body, and is used to control the air flow rate flowing through the fan and change the working power of the fan, and a wind shield control device is provided in the machine body, and is used to control the movement of the wind shield to adjust the air flow rate flowing through the fan.

[0011] In an embodiment of the present application, a windshield and windshield control device are provided in the drying duct of the clothing processing device to adjust the air flow through the fan, thereby reducing the fan's operating power. While maintaining the same output power of the drive device, the speeds of the drum and fan are further increased, meeting the required drum speed. This approach reduces the output power requirement of the drive device and reduces economic costs, enabling the clothing processing device to achieve a higher drum speed while maintaining a fixed maximum drive device power. This significantly increases the drum speed, surpassing the upper limit of drum speed achieved with conventional methods.

[0012] In one embodiment of the present application, the condensing device includes a compressor, a condenser and an evaporator; the compressor is installed in the body, the exhaust port of the compressor is connected to one end of the condenser, the return air port of the compressor is connected to one end of the evaporator, the other end of the condenser is connected to the other end of the evaporator, the evaporator and the condenser are arranged at intervals in the drying air duct, and the condenser is arranged on the side of the evaporator close to the air outlet component.

[0013] In the embodiment of the present application, a heating device is used in conjunction with a condenser to increase the air heating rate; a condenser is used in conjunction with an evaporator to increase the condensation rate, which is beneficial to reducing the workload of the compressor, reducing frequent shutdowns of the compressor due to excessively high system temperature, improving clothing processing efficiency, and shortening clothing processing time.

[0014] In one embodiment of the present application, the wind shield is attached to a side of the clothes drying chamber close to the air inlet component.

[0015] In an embodiment of the present application, the fan is arranged in the drying air duct, and the wind shield is attached to the side of the drying chamber close to the air inlet component to control the air flow entering the drying air duct and then control the air flow flowing through the fan, so that the working power of the fan can be controlled.

[0016] In one embodiment of the present application, the wind shield is arranged in the drying air duct and is arranged on a side of the fan close to the air inlet component.

[0017] In an embodiment of the present application, the wind shield is arranged in the drying air duct and on the side of the fan close to the air inlet component to directly control the air flow passing through the fan, so that the working power of the fan can be controlled.

[0018] In one embodiment of the present application, the wind shield member includes a wind shield fixture and a wind shield movable member; the wind shield fixture is provided with a main ventilation hole, and the main ventilation hole is used for air to pass through the drying chamber; the wind shield movable member is attached to any side of the main ventilation hole of the wind shield fixture, and the wind shield movable member is provided with a secondary ventilation hole, and the wind shield movable member can be attached to the wind shield fixture and moved to change the degree of overlap between the main ventilation hole and the secondary ventilation hole.

[0019] In an embodiment of the present application, the windshield includes a fixed windshield member and a movable windshield member. Both the fixed windshield member and the movable windshield member are provided with ventilation holes, namely, a main ventilation hole and a secondary ventilation hole. When the main ventilation hole and the secondary ventilation hole overlap, air can pass through the windshield member normally without being affected. When the main ventilation hole and the secondary ventilation hole are misaligned, the movable windshield member can block a portion of the main ventilation hole, preventing air from passing through, thereby controlling the air flow through the fan. This makes the operating power of the fan controllable. In actual control, the air flow can be controlled by moving the movable windshield member a small distance, reducing the difficulty of control.

[0020] In one embodiment of the present application, the wind-shielding movable member is provided with a linkage member in any movable direction thereof, and an elastic member is provided in the direction opposite to the direction of the linkage member.

[0021] In an embodiment of the present application, the windshield member is provided with a linkage member in any direction in which it can move, and an elastic member is provided in the direction opposite to the linkage member. In the initial position of the windshield member, the elastic member secures the windshield member using its own elastic force, keeping it stationary when not needed to block the wind, preventing it from affecting air flow. When movement is required, simply increasing the tension on the linkage member can reduce air flow. When movement is not required, simply not applying tension to the linkage member will cause the elastic member to retract due to its own contraction properties. This makes operation of the windshield member more convenient, making it easier to control the air flow through the fan.

[0022] In one embodiment of the present application, the wind shield control device is an electromagnetic device, which is installed in the body; when the electromagnetic device is powered on, it attracts the linkage part, driving the wind shield moving part to move in the direction of the linkage part; when the electromagnetic device is powered off, it stops attracting the linkage part, and the elastic part drives the wind shield moving part to move in the direction of the elastic part.

[0023] In the embodiment of the present application, an electromagnetic device is provided to realize automatic control of the windshield moving part, thereby making it easier to control the size of the air flow passing through the windshield part.

[0024] On the second aspect, in one embodiment of the present application, a control method for a clothing processing device using any one of the above embodiments is provided, the control method comprising: when entering the high-speed drum program, moving the wind shield by the wind shield control device to reduce the air flow through the fan, and the output power of the drive device remains unchanged; if the speed of the drum increases to the set speed, continuing to control the drive device to keep the output power unchanged until the high-speed drum program is completed.

[0025] In an embodiment of the present application, by providing a windshield and a windshield control device in the drying air duct of the clothing processing device, the air flow through the fan is adjusted, thereby reducing the working power of the fan. When the output power of the driving device is fixed, the rotation speed of the fan and the drum is further increased to meet the demand for the drum rotation speed. In the above manner, the requirements for the output power of the driving device are reduced, the economic cost is reduced, and the clothing processing device can meet a higher drum rotation speed when the maximum output power of the driving device is fixed. When the clothing processing device enters the high-speed drum program, the windshield control device is controlled to move the windshield, reducing the air flow through the fan, thereby reducing the working power of the fan. In this case, the output power of the driving device is maintained. When the output power of the driving device remains unchanged, the output power of the driving device is greater than the sum of the working power of the fan and the drum, and the rotation speed of the fan and the drum is increased. The increase in the drum rotation speed achieves the technical effect of automatically increasing the drum rotation speed under the same output power of the driving device, reduces power loss, and improves the user experience.

[0026] In one embodiment of the present application, when entering the high-speed drum program, after the wind shield is moved by the wind shield control device, the method further includes: if the speed of the drum does not increase to the set speed, the wind shield is continued to move by the wind shield control device to further reduce the air flow through the fan until the speed of the drum increases to the set speed or the wind shield cannot move; if the wind shield cannot move, the drive device is controlled to increase the output power until the speed of the drum increases to the set speed.

[0027] In the embodiment of the present application, the air flow rate through the fan is gradually reduced, and the rotation speed of the drum is gradually increased until the rotation speed of the drum reaches the set speed. While ensuring the maximum air flow rate, the rotation speed of the drum reaches the set speed, thereby ensuring the efficiency of laundry processing.

[0028] On the other hand, only when the windshield cannot move and the drum speed has not reached the set speed will the drive device be controlled to increase output power until the drum speed reaches the set speed. This ensures that the drive device always outputs the minimum power required to meet the set speed, avoiding unnecessary resource consumption and optimizing the customer experience.

[0029] In one embodiment of the present application, after the drum high-speed rotation program is executed, the method further includes: if the drum high-speed rotation program is executed, controlling the wind shield to return to the position before the movement.

[0030] In the embodiment of the present application, complete automatic control of the windshield is achieved, so that when there is no need to control the windshield to block the wind, the windshield function is automatically canceled, which improves the user experience.

[0031] According to at least one of the embodiments of the present application, the requirements for the output power of the driving device can be reduced, thereby reducing economic costs, so that the clothing processing device can meet a higher drum speed when the maximum power of the driving device is fixed, greatly improving the drum speed, and breaking through the upper limit of the drum speed under traditional methods.

[0032] According to at least one of the embodiments of the present application, the heating device is used in conjunction with the condenser, and the condenser is used in conjunction with the evaporator to increase the condensation speed, reduce the workload of the compressor, reduce frequent shutdowns of the compressor due to excessively high system temperature, improve clothing processing efficiency, and shorten clothing processing time.

[0033] According to at least one of the embodiments of the present application, the air flow rate entering the drying air duct can be controlled, thereby controlling the air flow rate flowing through the fan, so that the operating power of the fan can be controlled.

[0034] According to at least one of the embodiments of the present application, the operating power of the fan is controllable by directly controlling the air flow rate flowing through the fan.

[0035] According to at least one of the embodiments of the present application, the wind shield member includes a wind shield fixed member and a wind shield moving member. In actual control, the air flow can be controlled by moving the wind shield moving member a small distance, thereby reducing the difficulty of control.

[0036] According to at least one of the embodiments of the present application, by providing an elastic member and a linkage member on the wind-shielding moving member, the manipulation of the wind-shielding moving member is more convenient, and the air flow rate flowing through the fan is more easily controlled.

[0037] According to at least one of the embodiments of the present application, an electromagnetic device is provided to realize automatic control of the windshield moving member, thereby making it easier to control the size of the air flow passing through the windshield member.

[0038] According to at least one of the embodiments of the present application, the rotation speed of the drum is gradually increased to reach a set rotation speed. Under the condition of ensuring maximum air flow, the rotation speed of the drum is made to reach the set rotation speed, thereby ensuring laundry processing efficiency.

[0039] According to at least one of the embodiments of the present application, complete automatic control of the wind shield is achieved, so that when there is no need to control the wind shield to shield the wind, the wind shield function is automatically canceled, thereby improving the user experience.

[0040] Other features and advantages of the present application will become apparent from the following detailed description, or may be learned in part by practice of the present application.

[0054] Conventional clothes drying devices often use a single drive unit to simultaneously drive both the fan and the drum. When the drum speed needs to be increased, the fan must also be driven, causing the fan speed to increase, even if the fan speed does not need to be increased. This results in excessively high power consumption by the drive unit as a whole.

[0055] The present application provides a clothes processing device, and the clothes processing device provided in the embodiment of the present invention can be used for washing and drying clothes. A clothes processing device of the present application may include a body, a drum, a fan, a driving device, a condensing device, and a windshield.

[0056] The housing can be used as a shell for a clothes processing device. A drying air duct can be defined within the housing. The drying air duct can be provided with an air inlet component and an air outlet component. It should be noted that the housing can also adopt other structural shapes, and its appearance can be designed according to needs.

[0057] The drum can be arranged in the machine body. A clothes drying chamber for drying clothes can be formed in the drum. The clothes drying chamber can be connected to the air inlet component and the air outlet component respectively.

[0058] The fan can be arranged in the machine body and can be used to drive the air in the drying air duct to flow from the air inlet component to the air outlet component.

[0059] The heating device can be arranged in the machine body and can be used to heat the air in the drying air duct.

[0060] The driving device can be arranged in the machine body and can be used to drive the drum and the fan to rotate.

[0061] The condensing device can be arranged in the machine body. The refrigeration device can be used to condense the air entering the drying air duct.

[0062] A windshield member may be disposed within the housing. The windshield member may be used to control the air flow through the fan and thereby vary the fan's operating power. A control device for the windshield member may be disposed within the housing. The windshield member may be used to control movement of the windshield member to adjust the air flow through the fan.

[0063] See also Figure 1 , Figure 1 A structural schematic diagram of a clothes treating device according to an embodiment of the present application is shown.

[0064] In some embodiments, a door (not shown) may be provided on the front side of the drum. The door may be used to open and close the clothing loading port on the front side of the drum, and thus to open and close the drying chamber therein.

[0065] In some embodiments, a driving device (not shown) may be provided in the machine body. The driving device may be provided outside the drum, and the driving device may be transmission-connected to the drum and the fan to drive the drum and the fan to rotate.

[0066] See also Figure 1 As shown, the drying duct can be provided in the machine body. The drying duct can be provided outside the drum. The drying duct can be used to continuously generate hot and dry air. The drying duct can transport hot and dry air into the drying chamber to achieve a drying effect for the clothes in the drying chamber. Specifically, an air outlet component can be formed at one end of the drying duct. The drying duct can be connected to the interior of the drum through the air outlet component, so that the drying duct is connected to one end of the drying chamber through the air outlet component. An air inlet component can be formed at the other end of the drying duct. The drying duct can be connected to the interior of the drum through the air inlet component, so that the drying duct is connected to the other end of the drying chamber through the air inlet component. Therefore, a circulation channel for air flow can be formed between the drying duct and the drying chamber, so that the hot and dry air generated in the drying duct can enter the drying chamber through the air outlet component to dry the clothes, and the hot and humid air generated in the drying chamber during the drying process can flow back into the drying duct.

[0067] In some embodiments, the drying duct's air outlet can be located on the back side of the drum, that is, the drying duct's air outlet communicates with the rear end of the drying chamber. Simultaneously, the drying duct's air inlet can be located on the peripheral wall of the drum's front end opening, that is, the drying duct's air inlet communicates with the front end of the drying chamber. Thus, hot, dry air within the drying duct can flow from the rear end of the drying chamber to the front end, flowing throughout the entire drying chamber, thereby improving the drying efficiency and effectiveness of the clothes within it.

[0068] In some embodiments, a condensing device (not shown in the figure) may be provided in the machine body. The condensing device may include a compressor. The condensing device may include a condenser. The condensing device may include an evaporator. The compressor may be installed in the machine body (not shown in the figure). The exhaust port of the compressor may be connected to one end of the condenser. The return air port of the compressor may be connected to one end of the evaporator. The other end of the condenser may be connected to the other end of the evaporator. The evaporator and the condenser may be arranged at intervals in the drying air duct. The condenser may be provided on the side of the evaporator close to the air outlet component.

[0069] The compressor's exhaust port can be connected to one end of the condenser. The other end of the condenser can be connected to one end of the evaporator. The other end of the evaporator can be connected to the compressor's return air port, thereby forming a refrigerant refrigeration cycle. The compressor can be used to compress the refrigerant. The compressed high-temperature, high-pressure refrigerant enters the condenser through the compressor's exhaust port and is condensed. After exiting the condenser, the refrigerant is sent to the evaporator for evaporation and cooling. The cooled refrigerant can then return to the compressor through the return air port and be compressed again, thus forming a refrigeration cycle.

[0070] The condenser absorbs heat from the refrigerant, generating heat that in turn heats the air in the drying duct, continuously generating hot air. Driven by the fan, the hot air is delivered through the air outlet to the drying chamber to dry the clothes. The hot and humid air generated during the drying process can re-enter the drying duct through the air inlet. The evaporator cools the hot and humid air, condensing it and removing moisture to create dry, cold air. The dry, cold air is then reheated by the condenser and heating device, returning to dry air and drying the clothes. This cycle repeats, forming a drying cycle that effectively dries the clothes in the drying chamber.

[0071] The heating device can be installed in the drying duct and on the side of the condenser near the air outlet component. The heating device is used to heat the air around it and the air flowing through the heating device. Therefore, after the air in the drying duct is heated by the condenser, it can be heated again by the heating device before being conveyed into the drying chamber. The heating device and the condenser work together to double heat the air in the drying duct, which can greatly increase the air temperature rise rate, so that the dry air can be raised to a better temperature. At the same time, it can effectively reduce the load on the compressor, which helps to reduce or avoid frequent compressor shutdowns due to excessive system temperature. This allows the heat pump system to operate continuously, improves drying efficiency, and shortens drying time.

[0072] In some embodiments, the heating device can be located in the drying duct at the rear of the drum and at the air outlet. The evaporator and condenser can both be located in the drying duct at the bottom of the drum. A fan can be located in the drying duct. The fan can be a turbine fan, which transports hot air generated by the condenser in the drying duct at the bottom of the drum into the drying duct at the rear of the drum, where it is heated again by the heating device and then enters the drying chamber through the air outlet.

[0073] In some embodiments, the windshield can be attached to the side of the drying chamber adjacent to the air inlet component. When the fan rotates, the hot and humid air in the drying chamber flows through the windshield and the air inlet component into the drying duct. The condensing device and heating device in the drying duct convert the hot and humid air into dry air, which then flows through the air outlet component into the drying chamber to dry the clothes.

[0074] When hot and humid air enters the drying duct, the air flow rate entering the drying duct can be controlled by the windshield, thereby controlling the air flow through the fan to reduce the fan's operating power at various speeds. This allows the drum and fan speeds to be increased while maintaining the current output power of the drive device. Increasing the drum speed achieves better laundry treatment results.

[0075] In some embodiments, the windshield can be provided in the drying air duct and on the side of the fan close to the air inlet component. That is, as long as the windshield is provided in the drying air duct and on the side of the fan close to the air inlet component, it can be provided at any position, and the air flow through the fan can be controlled to reduce the operating power of the fan at various speeds. This allows the speed of the drum and the fan to increase while the current output power of the drive device remains unchanged. Increasing the speed of the drum can achieve a better treatment effect on the clothes. This also allows for more possibilities in setting the position of the windshield.

[0076] In some embodiments, the windshield can be directly attached to the air inlet side of the fan, thereby achieving more precise control of the air flow through the fan and more precise control of the fan's operating power at various speeds.

[0077] When the wind shield is directly attached to the air inlet side of the fan, it is not necessary to open a ventilation hole, and the wind shield can directly block the air inlet side of the fan to reduce the air flow passing through the fan.

[0078] See also Figure 1 and Figure 2 , Figure 2 A schematic diagram of the structure of a windshield according to an embodiment of the present application is shown. In some embodiments, the windshield may include a windshield fixture and a windshield movable member. The windshield fixture may be provided on a side of the blower close to the air inlet component. The windshield fixture may be provided with a main ventilation hole. The main ventilation hole may be used for air passing through the drying chamber. The windshield movable member may be provided on a side of the blower close to the air inlet component, and the windshield movable member may be attached to any side of the main ventilation hole of the windshield fixture. The windshield movable member may be provided with a secondary ventilation hole. The windshield movable member may be attached to the windshield fixture for movement. It is used to change the degree of overlap between the main ventilation hole and the secondary ventilation hole.

[0079] The windshield movable member and the windshield fixing member can be slidably connected. The windshield fixing member can be provided with at least one main ventilation hole. The windshield movable member can be provided with at least one secondary ventilation hole. When the windshield member is not needed to block the wind and reduce the air flow through the fan, the main ventilation hole is completely unobstructed, that is, the secondary ventilation hole on the windshield movable member completely overlaps with the main ventilation hole, or the windshield movable member does not block the main ventilation hole at all. When windshield is required, the main ventilation hole is partially blocked, and the size of the blocked portion of the main ventilation hole can be adjusted as needed.

[0080] For example, when the main vent and the secondary vent are both one, and when a windshield is not needed to block the wind and reduce the air flow through the fan, the main vent and the secondary vent are completely overlapped, or the main vent and the secondary vent are completely offset to ensure unimpeded air flow through the fan. When a windshield is needed to block the wind and reduce the air flow through the fan, the main vent and the secondary vent are partially overlapped to control the air flow through the fan.

[0081] See also Figure 3 and Figure 4 , Figure 3 A schematic diagram showing the complete overlap of the main ventilation holes and the secondary ventilation holes according to an embodiment of the present application is shown. Figure 4 A schematic diagram of a partially blocked main vent according to an embodiment of the present application is shown. When there are multiple main vents and multiple secondary vents, when there is no need for a windshield to block the wind and reduce the air flow through the fan, some of the main vents completely overlap with the secondary vents, or the main vents and secondary vents are completely misaligned to ensure unimpeded air flow through the fan. When a windshield is needed to block the wind and reduce the air flow through the fan, some of the main vents are partially blocked by the gaps between the secondary vents ( Figure 4 The gray circular holes are the blocked main ventilation holes and secondary ventilation holes to control the air flow through the fan.

[0082] In some embodiments, the windshield fixture may be provided with a plurality of main ventilation holes. The windshield movable member may not be provided with secondary ventilation holes. When the windshield fixture is required to block wind and reduce the air flow through the blower, the windshield movable member is controlled to block some of the main ventilation holes on the windshield fixture. If there is one or more main ventilation holes, blocking only some of the ventilation holes is sufficient. Air flow is required during the laundry processing process, and completely blocking the main ventilation holes will prevent air flow.

[0083] In some embodiments, to facilitate the movement of the windshield movable member, a linkage member may be provided in any movable direction of the windshield movable member. The windshield movable member may be provided with an elastic member in the direction opposite to the direction of the linkage member.

[0084] In the initial position of the windshield, the elastic member secures the windshield member using its own elastic force, keeping it stationary when not needed to block the wind, preventing it from affecting air flow. When movement is required, simply increasing the tension on the linkage member reduces air flow. When movement is no longer required, simply removing the tension from the linkage member allows the elastic member to retract, returning the windshield member to its original position. This makes operating the windshield member more convenient, making it easier to control the air flow.

[0085] In some embodiments, the windshield control device may be an electromagnetic device. The electromagnetic device may be mounted within the housing. When the electromagnetic device is energized, it attracts the linkage member, driving the windshield moving member toward the linkage member. When the electromagnetic device is de-energized, it stops attracting the linkage member, allowing the elastic member to drive the windshield moving member toward the elastic member. In embodiments of the present application, the electromagnetic device is provided to achieve automated control of the windshield moving member, making it easier to control the amount of air flowing through the windshield.

[0086] Based on the above clothes processing device, Figure 5 As shown, Figure 5A flow chart of a control method for a laundry processing apparatus according to an embodiment of the present application is shown. The present application provides a control method for a laundry processing apparatus, including the following steps:

[0087] Step S210, when entering the high-speed drum program, the windshield member control device moves the windshield member to reduce the air flowing through the fan, and the output power of the drive device remains unchanged;

[0088] In step S220, if the rotation speed of the drum increases to the set rotation speed, the driving device is controlled to maintain the working power until the high rotation speed program of the drum is completed.

[0089] The above two steps are described in detail below.

[0090] In step S210, when the laundry processing device enters the high-speed drum cycle, the drum speed must be increased. Because the drive unit is simultaneously connected to the fan and the drum, directly controlling the drive unit to increase both speeds would require the required power output of both the fan and the drum at the increased speeds, placing a significant burden on the drive unit. In some cases, the drive unit's maximum power is insufficient to simultaneously increase the fan and drum speeds, forcing the drum to rotate at a lower speed, significantly reducing the laundry processing efficiency.

[0091] Therefore, in the embodiment of the present application, the air flow through the fan is reduced by the wind shield to reduce the operating power of the fan, so that the output power demand of the driving device will be reduced as a whole, so that the driving device can make the fan and the drum reach a higher speed at the same output power.

[0092] When the laundry processing device enters the high-speed drum cycle, the windshield control device controls the windshield to block air flowing toward the fan's air inlet, thereby reducing the air flow through the fan. During this period, the drive device is controlled to maintain a constant output power. Since the fan's operating power decreases, the overall operating power required by the laundry processing device decreases. Therefore, maintaining the drive device's output power unchanged during this period will increase the speed of the drum and fan.

[0093] In step S220, if the drum speed reaches the set speed required for the high-speed program, the output device is controlled to maintain the output power unchanged until the high-speed program is completed. If the drum speed exceeds the set speed required for the high-speed program, the output power of the drive device is controlled to be reduced to save energy.

[0094] See also Figure 6 , Figure 6A flow chart of controlling the drum speed after the windshield member is moved by the windshield member control device when the drum enters the high-speed rotation program according to one embodiment of the present application is shown. This embodiment of the present application provides steps for controlling the drum speed, including:

[0095] Step S301: If the speed of the drum does not increase to the set speed, the windshield control device causes the windshield to continue to move, further reducing the air flowing through the fan, until the speed of the drum increases to the set speed or the windshield cannot move;

[0096] Step S302: If the windshield cannot move, the driving device is controlled to increase the output power until the rotation speed of the drum increases to the set rotation speed.

[0097] The above two steps are described in detail below.

[0098] In step S301, if the drum speed still cannot reach the speed required by the drum high-speed program after controlling the wind shield to block the air flowing to the leeward side of the fan, continue to control the wind shield to further block the air flowing to the leeward side of the fan, and reduce the air flow through the fan. In this process, since the output power of the drive device remains unchanged, the working power of the fan is constantly decreasing, and the speed of the drum continues to increase. If the speed of the drum reaches the set speed during this process, the wind shield is controlled not to move, and the output power of the drive device is maintained.

[0099] For example, the windshield's movement is divided into several levels, such as level 1, level 2, level 3, and so on, based on the windshield's shielding effect. Each level determines whether the drum speed has reached the set speed. If so, movement stops. If not, movement continues until the set speed is reached or the windshield reaches the last level, where it cannot move. Further increasing the shielding effect at this point, such as continuing to block the main vents, will result in insufficient air flow through the fan, affecting the cleaning effect on the clothes.

[0100] Corresponding to the above-mentioned structural embodiment, multiple magnetic induction devices can be set up to move the wind-shielding member step by step to increase the wind-shielding effect, or by setting up an electric device for the wind-shielding member, the wind-shielding member can gradually increase the proportion of blocking the main ventilation holes to increase the wind-shielding effect.

[0101] If the wind shield is moved to a point where it can no longer be moved, the driving device is controlled to increase the output device to increase the drum speed until the drum speed reaches the set speed.

[0102] Only when the windshield becomes immobile and the drum speed has not reached the set speed does the drive unit increase its output power until the drum speed reaches the set speed. This ensures the drive unit always maintains the minimum output power required to reach the set speed, avoiding unnecessary resource consumption and optimizing the customer experience.

[0103] It should be noted that in another embodiment of the present application, when entering the high-speed drum program, the output power of the drive device can be gradually increased to increase the drum speed until the drum speed reaches the set speed. If the output power of the drive device reaches the maximum value and the drum speed has not reached the set speed, the windshield member is activated again to reduce the operating power of the fan or gradually reduce the operating power of the fan to increase the drum speed until the set speed is reached.

[0104] In one embodiment of the present application, after the high-speed drum program is executed, the wind shield is controlled to reset to the position before the movement in preparation for the next activation, and the air flow of the flow-reducing fan is stopped, and the air output of the air outlet component is increased, thereby producing a better treatment effect on the clothes.
