Abstract

The present application relates to the technical field of clothes processing, and particularly provides a clothes processing device control method and clothes processing device. Specifically, the clothes processing device of the present application is additionally provided with a bypass assembly, a first air door and a second air door. The air inlet end of the bypass assembly is in communication with the circulating air duct. The first air outlet and the second air outlet of the bypass assembly are both in communication with the drum. The bypass assembly can send part of the airflow in the circulating air duct back to the drum to perform heat and moisture exchange with the clothes again. Since the part of the airflow has not performed heat exchange with the dehumidifying member in the circulating air duct, the part of the airflow is sent back to the drum to perform heat and moisture exchange with the clothes again, so that the water content of the airflow is increased and the temperature is decreased, which is beneficial to improving the drying efficiency and reducing the drying time. The present application can also determine whether to open the first air door or the second air door according to the rotation direction of the drum, so that the sprayed airflow can be more effectively blown onto the clothes in the drum to perform more sufficient heat and moisture exchange with the clothes, which is more beneficial to improving the drying efficiency.

Description

Technical Field

[0001] This invention relates to the field of clothing processing technology, and specifically provides a control method for clothing processing equipment and clothing processing equipment. Background Technology

[0002] Existing garment processing equipment mainly includes dryers and washer-dryer combos.

[0003] Taking a clothes dryer as an example, a clothes dryer is a device used to dry clothes. It mainly includes a cabinet and a drum and drying unit installed inside the cabinet. The drying unit is connected to the drum and can deliver hot air into the drum to dry the clothes inside. However, the drying time of existing clothes dryers is relatively long, resulting in a poor user experience.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problem, namely, to solve the problem of long drying time in existing clothing processing equipment.

[0006] In a first aspect, the present invention provides a control method for a garment processing device, the garment processing device including a drum and a drying device, the drying device including a circulating air duct communicating with the drum and a dehumidifying component installed in the circulating air duct, the dehumidifying component being used to dehumidify the circulating airflow in the circulating air duct, the drying device further including a bypass component and a first damper and a second damper installed on the bypass component, the air inlet end of the bypass component communicating with the circulating air duct, the position of the circulating air duct communicating with the bypass component being located upstream of the dehumidifying component along the airflow direction, the bypass component having a first air outlet and a second air outlet, both the first air outlet and the second air outlet being communicating with the drum, the bypass component being able to send a portion of the airflow entering the circulating air duct back to the drum to exchange heat and moisture again with the clothes in the drum, the first air outlet and the second air outlet being respectively disposed facing the right side wall and the left side wall of the drum, the first damper being used to open / close the first air outlet, the second damper being used to open / close the second air outlet, the control method including:

[0007] When the bypass component is running, the rotation direction of the roller is obtained;

[0008] Depending on the rotation direction of the roller, the first damper or the second damper may be opened selectively.

[0009] In the preferred embodiment of the above control method, the step of "selectively opening the first damper or the second damper according to the rotation direction of the drum" specifically includes:

[0010] If the rotation direction of the roller is from right to left, then the first damper is opened;

[0011] If the roller rotates from left to right, then the second damper is opened.

[0012] In a preferred embodiment of the above control method, the control method further includes:

[0013] During the drying process, the humidity value in the drum is acquired;

[0014] The bypass component is selectively operated based on the humidity value.

[0015] In the preferred embodiment of the above control method, the step of "selectively operating the bypass component according to the humidity value" specifically includes:

[0016] The humidity value is compared with a preset value;

[0017] If the humidity value is less than the preset value, the bypass component is activated.

[0018] In the preferred embodiment of the above control method, both the first air outlet and the second air outlet are located directly in front of the cylinder opening of the roller. The airflow ejected from the first air outlet and the second air outlet enters the roller through the cylinder opening. The airflow direction of the first air outlet and the airflow direction of the second air outlet are both set at an angle to the axial direction of the roller.

[0019] In a preferred embodiment of the above control method, the position of the first air outlet corresponds to the left side region of the cylinder opening, and the position of the second air outlet corresponds to the right side region of the cylinder opening; or

[0020] The position of the first air outlet corresponds to the right side region of the cylinder opening, and the position of the second air outlet corresponds to the left side region of the cylinder opening.

[0021] In the preferred embodiment of the above control method, the circulating air duct is located below the drum and the air inlet of the circulating air duct is set close to the bottom of the cylinder opening. The positions of the first air outlet and the second air outlet are both corresponding to the upper half of the cylinder opening.

[0022] In a preferred embodiment of the above control method, the bypass assembly includes a bypass pipe, a fan, and a support member. The support member is located in front of the roller. The first air outlet and the second air outlet are both disposed on the support member. The first damper and the second damper are both installed on the support member. The bypass pipe is installed on the support member. The air inlet end of the bypass pipe is connected to the circulating air duct. The air outlet end of the bypass pipe is connected to the first air outlet and the second air outlet. The fan is installed in the bypass pipe.

[0023] In the preferred embodiment of the above control method, the circulating air duct includes an inlet air duct, a heat exchange air duct, and an outlet air duct connected in sequence. The inlet air duct is disposed within the support member, with its inlet end located near the cylinder opening. The inlet of the bypass pipe is connected to the inlet air duct. The dehumidification member is disposed within the heat exchange air duct. Multiple ventilation openings are provided on the rear cylinder wall of the drum, and the outlet end of the outlet air duct is located near the rear cylinder wall.

[0024] In a second aspect, the present invention also provides a garment processing apparatus, including a controller configured to perform the control method described above.

[0025] When adopting the above technical solution, the clothing processing device of the present invention connects the circulating air duct to the drum by setting a bypass component. The bypass component allows a portion of the airflow in the circulating air duct to be returned to the drum. Since the connection point between the circulating air duct and the bypass component is located upstream of the dehumidifying component, this portion of the airflow has not yet undergone heat exchange with the dehumidifying component. The airflow returned to the drum can then exchange heat and moisture with the clothing in the drum again, increasing the moisture content and lowering the temperature of the airflow. This airflow then re-enters the circulating air duct to exchange heat with the evaporator, improving the condensation effect and thus enhancing the drying efficiency. This invention improves drying efficiency and reduces drying time. Furthermore, the bypass assembly has a first air outlet and a second air outlet, with a first damper and a second damper installed at each outlet. When the bypass assembly is running, the first and second dampers are not opened simultaneously; only one is opened. This results in stronger airflow. Additionally, the invention can determine whether to open the first or second damper based on the rotation direction of the drum, allowing the airflow from the outlet to more effectively reach the clothes in the drum, thus facilitating more thorough heat and moisture exchange and further improving drying efficiency.

[0026] Furthermore, the present invention determines the start-up timing of the bypass component based on the humidity value in the drum, so that the bypass component starts at the appropriate time, which is more conducive to improving drying efficiency and reducing drying time.

[0027] Furthermore, the garment processing device of the present invention, by setting both the first air outlet and the second air outlet directly in front of the drum opening, allows the airflow ejected from the first air outlet and the second air outlet to enter the drum from the drum opening, resulting in better performance.

[0028] Furthermore, the present invention optimizes the layout by setting a support member in front of the roller, setting both the first air outlet and the second air outlet on the support member, and also setting the air inlet of the circulating air duct inside the support member, and connecting the air inlet of the circulating air duct with the first air outlet and the second air outlet through a bypass pipe.

[0029] Furthermore, the garment processing device of the present invention, by setting the air inlet of the circulating air duct close to the bottom of the drum opening, and by aligning the first air outlet and the second air outlet with the upper half of the drum opening, allows the airflow to exit from the lower part of the drum opening, while the airflow ejected from the first air outlet and the second air outlet enters the drum from the upper half of the drum opening, resulting in better performance, improved drying efficiency, and reduced drying time.

[0041] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the invention and are not intended to limit the scope of protection of the invention. For example, although the embodiments described below are in conjunction with a clothes dryer, the technical solutions of the present invention are also applicable to other clothing processing equipment with drying functions, such as washer-dryer combos.

[0042] It should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "set," "connect," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0043] Specifically, the present invention provides a clothes dryer, such as Figure 1 and Figure 2 As shown, the dryer of the present invention includes a housing (not shown), a door 6, a drum 1, and a drying device. The drum 1 is rotatably installed in the housing, and the drying device is connected to the drum 1 and can deliver hot air into the drum 1 to dry the clothes in the drum 1.

[0044] Preferably, such as Figure 1 As shown, the drying device of the present invention includes a circulating air duct 2, a fan 4, and a drying module. The circulating air duct 2 is connected to the drum 1. The drying module includes a compressor (not shown in the figure), an evaporator 31, a condenser 32, a refrigerant pipeline, and a throttling element installed on the refrigerant pipeline. The refrigerant pipeline connects the compressor to the evaporator 31 and the condenser 32 to form a refrigerant circulation loop. The evaporator 31 and the condenser 32 are installed in the circulating air duct 2. Along the flow direction of the airflow, the evaporator 31 is located upstream of the condenser 32. The fan 4 is used to make the airflow circulate in the drum 1 and the circulating air duct 2.

[0045] When the drying mode is executed, the fan 4 and the compressor are started. Under the action of the fan 4, the airflow circulates between the drum 1 and the circulating air duct 2. The evaporator 31 is used to dehumidify the circulating airflow in the circulating air duct 2, and the condenser 32 is used to heat the airflow in the circulating air duct 2.

[0046] For example, such as Figure 1 As shown, the drum 1 is horizontally arranged. The right end of the drum 1 has a drum opening 11, through which the user can put and take out clothes. The left end of the drum 1 is the rear drum wall 12, which has multiple vents 13. The circulating air duct 2 is located below the drum 1. The air inlet of the circulating air duct 2 is located near the bottom of the drum opening 11, and the air outlet of the circulating air duct 2 extends to the rear drum wall 12 of the drum 1. The fan 4 is installed in the circulating air duct 2 and is located near the air outlet of the circulating air duct 2. After the fan 4 is turned on, the hot and humid air in the drum 1 is discharged from the drum opening 11 and enters the circulating air duct 2. When the hot and humid air flows through the evaporator 31, it exchanges heat with the evaporator 31. The moisture carried by the hot and humid airflow condenses. When the circulating airflow flows through the condenser 32, it absorbs the heat dissipated by the condenser 32, and the temperature rises. The high-temperature airflow returns to the drum 1 from the vents 13 on the rear drum wall 12 and exchanges heat and moisture with the clothes in the drum 1.

[0047] It should be noted that the location of the fan 4 is not limited to the position near the air outlet of the circulating air duct 2 as described above. For example, it can also be located near the air inlet of the circulating air duct 2, or between the evaporator 31 and the condenser 32. In addition, the fan 4 can also be installed outside the circulating air duct 2. For example, the fan 4 can be located behind the drum 1, with the exhaust port of the fan 4 facing the rear wall 12 of the drum 1, and the air outlet of the circulating air duct 2 connected to the air inlet of the fan 4. Alternatively, the fan 4 can be located near the drum opening 11, with the air inlet of the fan 4 facing the drum opening 11, and the exhaust port of the fan 4 connected to the air inlet of the circulating air duct 2, etc. Such adjustments and changes to the specific location of the fan 4 do not deviate from the principles and scope of the present invention and should be limited to the protection scope of the present invention.

[0048] Furthermore, it should be noted that the circulating air duct 2 is not limited to being located below the roller 1. For example, the circulating air duct 2 can also be located above or on the side of the roller 1. Of course, the present invention preferably places the circulating air duct 2 below the roller 1.

[0049] Furthermore, it should be noted that those skilled in the art can also omit the heat pump module in practical applications and use other types of dehumidifying and heating components to replace the evaporator and condenser for dehumidifying and heating the circulating airflow in the circulating air duct 2. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be limited to the protection scope of the present invention.

[0050] The technical solution of this invention will be further described below using a heat pump module as an example.

[0051] Preferably, such as Figures 1 to 6 As shown, the drying device of the present invention also includes a bypass component. The air inlet of the bypass component is connected to the circulating air duct 2. Along the flow direction of the airflow, the position where the circulating air duct 2 is connected to the bypass component is located upstream of the dehumidifying component (i.e., the evaporator 31). The air outlet of the bypass component is connected to the drum 1. The bypass component can send a portion of the airflow entering the circulating air duct 2 back to the drum 1 to exchange heat and moisture with the clothes in the drum 1 again.

[0052] As the drying mode is running, the humidity of the clothes in drum 1 will gradually decrease. In the middle and later stages of drying, the air discharged from drum 1 has a low moisture content and a high temperature. When it flows through evaporator 31, the condensation effect is poor, resulting in extremely low drying efficiency and a long drying time.

[0053] This invention connects the circulating air duct 2 to the drum 1 by setting a bypass component. In the middle and later stages of drying, the bypass component can be activated to send a portion of the airflow in the circulating air duct 2 back into the drum 1. Since the connection between the circulating air duct 2 and the bypass component is located upstream of the evaporator 31, this portion of the airflow has not yet exchanged heat with the evaporator 31. The airflow sent back into the drum 1 can exchange heat and moisture with the clothes in the drum 1 again, increasing the moisture content and lowering the temperature of the airflow. Then, it enters the circulating air duct 2 to exchange heat with the evaporator 31, which helps to improve the condensation effect, thereby increasing the drying efficiency and reducing the drying time.

[0054] Preferably, Figures 1 to 6 As shown, the bypass assembly of the present invention has a first air outlet 531 and a second air outlet 532. Both the first air outlet 531 and the second air outlet 532 are connected to the drum 1. The first air outlet 531 is disposed facing the right side wall of the drum 1, and the second air outlet 532 is disposed facing the left side wall of the drum 1. The drying device of the present invention also includes a first damper (not shown in the figure) and a second damper (not shown in the figure) installed on the bypass assembly. The first damper is used to open / close the first air outlet 531, and the second damper is used to open / close the second air outlet 532.

[0055] In other words, the airflow ejected from the first air outlet 531 can reach the right side wall of the roller 1, and the airflow ejected from the second air outlet 532 can reach the left side wall of the roller 1.

[0056] It should be noted that during the operation of the bypass component, only the first air damper can be opened to open the first air outlet 531, allowing airflow to be ejected from the first air outlet 531 and flow toward the right side wall of the roller 1. Alternatively, only the second air damper can be opened to open the second air outlet 532, allowing airflow to be ejected from the second air outlet 532 and flow toward the left side wall of the roller 1. Or, both the first and second air dampers can be opened simultaneously, or the first and second air dampers can be opened alternately.

[0057] Furthermore, it should be noted that although the first air outlet 531 and the second air outlet 532 in the figure are both circular, this does not constitute a limitation of the present invention. Those skilled in the art can also set the first air outlet 531 and the second air outlet 532 to be square or rectangular, etc., in practical applications.

[0058] Preferably, such as Figures 1 to 6 As shown, the first air outlet 531 and the second air outlet 532 of the bypass component of the present invention are both located directly in front of the cylinder opening 11 of the roller 1. The airflow ejected from the first air outlet 531 and the second air outlet 532 enters the roller 1 through the cylinder opening 11 of the roller 1. The air outlet direction of the first air outlet 531 and the air outlet direction of the second air outlet 532 are both set at an angle to the axial direction of the roller 1.

[0059] In other words, the first air outlet 531 and the second air outlet 532 are both arranged opposite to the cylinder opening 11 of the roller 1. Furthermore, the first air outlet 531 and the second air outlet 532 do not emit air along the axial direction of the roller 1, but rather at a certain angle to the axial direction of the roller 1. When viewed along the axial direction of the roller 1, it is equivalent to emitting air at an angle, so that the airflow ejected from the first air outlet 531 can blow onto the right side of the roller 1, and the airflow ejected from the second air outlet 532 can blow onto the left side of the roller 1.

[0060] Preferably, such as Figures 1 to 6 As shown, the position of the first air outlet 531 of the bypass component corresponds to the left side of the cylinder opening 11 of the roller 1, and the position of the second air outlet 532 of the bypass component corresponds to the right side of the cylinder opening 11.

[0061] That is, the first air outlet 531 is located to the left of the vertical center line of the cylinder opening 11 of the roller 1, and the first air outlet 531 blows air obliquely to the right; the second air outlet 532 is located to the right of the vertical center line of the cylinder opening 11 of the roller 1, and the second air outlet 532 blows air obliquely to the left.

[0062] It should be noted that, in practical applications, those skilled in the art can also position the first air outlet 531 to correspond to the right side of the cylinder opening 11, and correspondingly, position the second air outlet 532 to correspond to the left side of the cylinder opening 11.

[0063] Preferably, such as Figures 1 to 6 As shown, the circulating air duct 2 is located below the roller 1 and the air inlet of the circulating air duct 2 is set close to the bottom of the cylinder opening 11 of the roller 1. The positions of the first air outlet 531 and the second air outlet 532 of the bypass component are both corresponding to the upper half of the cylinder opening 11 of the roller 1.

[0064] By positioning the air inlet of the circulating air duct 2 close to the bottom of the cylinder opening 11 of the drum 1, and aligning the first air outlet 531 and the second air outlet 532 with the upper half of the cylinder opening 11 of the drum 1, the airflow in the drum 1 is discharged from the lower half of the cylinder opening 11, while the airflow ejected from the first air outlet 531 and the second air outlet 532 enters the drum 1 from the upper half of the cylinder opening 11. This method is more effective, improves drying efficiency, and reduces drying time.

[0065] Preferably, such as Figures 1 to 6 As shown, the bypass assembly of the present invention includes a bypass pipe 51, a fan 52, and a support member 53. The support member 53 is located in front of the roller 1. The first air outlet 531 and the second air outlet 532 are both disposed on the support member 53. The first damper and the second damper are both installed on the support member 53. The bypass pipe 51 is installed on the support member 53. The air inlet end of the bypass pipe 51 is connected to the circulating air duct 2. The air outlet end of the bypass pipe 51 is connected to the first air outlet 531 and the second air outlet 532. The fan 52 is installed in the bypass pipe 51.

[0066] For example, the fan 52 is installed near the air inlet of the bypass duct 51. When the bypass component needs to be operated in the middle or later stages of drying, the fan 52 is started. Under the action of the fan 52, a portion of the airflow that just entered the circulating air duct 2 is drawn into the bypass duct 51 and then flows back into the drum 1 along the bypass duct 51 to exchange heat and moisture with the clothes in the drum 1 again. Preferably, the fan 52 is an ultra-high speed fan.

[0067] It should be noted that, in practical applications, those skilled in the art can also place the fan 52 at other locations within the bypass duct 51, such as in the middle of the bypass duct 51 or near the air outlet end of the bypass duct 51. Of course, the present invention preferably places the fan 52 near the air inlet end of the bypass duct 51.

[0068] Furthermore, it should be noted that the present invention does not limit the specific structural form of the support member 53. For example, the support member 53 can be set as a support plate or a support frame, etc.

[0069] Furthermore, it should be noted that the present invention does not limit the specific structural form of the first air damper and the second air damper. For example, both the first air damper and the second air damper can be set as a motor + sealing plate structure. Taking the first air damper as an example, the motor is fixedly installed on the support member and close to the first air outlet. The sealing plate is located inside the first air outlet. The motor is connected to the sealing plate and can drive the sealing plate to rotate so as to open / close the first air outlet.

[0070] Preferably, such as Figures 1 to 4 As shown, the circulating air duct 2 of the present invention includes an air inlet duct 21, a heat exchange duct 22 and an air outlet duct 23 connected in sequence. The air inlet duct 21 is disposed in the support member 53. The air inlet end of the air inlet duct 21 is disposed near the cylinder opening 11 of the roller 1. The air inlet end of the bypass pipe 51 is connected to the air inlet duct 21. The dehumidification member is disposed in the heat exchange duct 22. The air outlet end of the air outlet duct 23 is disposed near the rear cylinder wall 12 of the roller 1.

[0071] For example, such as Figure 1 As shown, the air inlet duct 21 is located at the lower right of the drum 1. The air inlet duct 21 extends vertically, and its top end is its air inlet end. It is located near the bottom of the drum 1's opening 11. The bottom end of the air inlet duct 21 is connected to the right end of the heat exchange duct 22. The heat exchange duct 22 is located directly below the drum 1. It extends horizontally and is parallel to the axis of the drum 1. The evaporator 31 and condenser 32 of the heat pump module are both installed in the heat exchange duct 22. The air outlet duct 23 is located at the lower left of the drum 1. The air outlet duct 23 also extends vertically, and its top end is its air outlet end. It is located near the rear wall 12 of the drum 1. The bottom end of the air outlet duct 23 is connected to the left end of the heat exchange duct 22. The fan 4 is installed in the air outlet duct 23.

[0072] For example, such as Figures 2 to 4As shown, the support member 53 includes a base and a support plate disposed on the base. An air inlet duct 21 is disposed inside the base, and a first opening communicating with the air inlet duct 21 is also provided on the base. One end of a bypass pipe 51 is inserted into the first opening and communicates with the air inlet duct 21. A first air outlet 531 and a second air outlet 532 are disposed on the inner side of the support plate. A connecting duct is disposed inside the support plate, and both the first air outlet 531 and the second air outlet 532 are communicated with the connecting duct. A second opening communicating with the connecting duct is provided on the outer side of the support plate, and the other end of the bypass pipe 51 is inserted into the second opening located on the support plate. The support plate is vertically disposed, and a pick-up and drop-off port 533 is provided on the support plate. The pick-up and drop-off port 533 is disposed corresponding to the opening 11 of the roller 1. When the dryer is running, the pick-up and drop-off port 533 is closed by the door 6 of the dryer.

[0073] During the drying process, the air discharged from the drum opening 11 of the drum 1 first enters the air inlet duct 21, and then enters the heat exchange duct 22 to exchange heat with the evaporator 31 and condenser 32 to achieve dehumidification and heating. Then, it flows along the air outlet duct 23 to the rear drum wall 12 of the drum 1, and returns to the drum 1 through the vent 13 on the rear drum wall 12. After the fan 52 of the bypass component is started, part of the airflow entering the air inlet duct 21 is drawn into the bypass pipe 51, flows along the bypass pipe 51 to the first air outlet 531 or the second air outlet 532, and is sprayed into the drum 1 from the first air outlet 531 or the second air outlet 532 to exchange moisture and heat with the clothes in the drum 1 again.

[0074] It should be noted that those skilled in the art can also set an opening at the location of the heat exchange duct 22 to connect with the bypass pipe 51, as long as the opening is located upstream of the evaporator 31.

[0075] Furthermore, it should be noted that, in practical applications, those skilled in the art can also install two branch pipes at the end of the bypass pipe, so that the two branch pipes are connected to the first air outlet and the second air outlet respectively. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be limited to the protection scope of the present invention.

[0076] Preferably, the dryer of the present invention further includes a lint collection device (not shown in the figure), which is installed in the air inlet duct 21.

[0077] By installing a wire shavings collection device in the air inlet duct 21, the airflow discharged from the cylinder opening 11 of the roller 1 enters the air inlet duct 21, first flows through the wire shavings collection device for filtration, and then enters the heat exchange duct 22. When the airflow flows through the wire shavings collection device, the wire shavings and other impurities carried in the airflow are trapped in the wire shavings collection device.

[0078] Preferably, the lint collection device is detachably installed in the air inlet duct 21. For example, the lint collection device can be inserted into the air inlet duct 21 from the top. When the lint collection device needs to be cleaned, the user can pull it out from the top of the air inlet duct 21 after opening the door 6.

[0079] Based on any of the dryers described above, the present invention also provides a control method for a dryer, such as... Figure 7 As shown, the control method of the dryer of the present invention includes the following steps:

[0080] When the bypass component is running, obtain the rotation direction of the roller;

[0081] Depending on the direction of the drum's rotation, the first or second air damper can be opened selectively.

[0082] In other words, when the bypass component is running, the first and second air dampers are not opened simultaneously, but only one of them is opened. In this way, only one of the first air outlet 531 and the second air outlet 532 emits air, resulting in stronger airflow. In addition, the present invention can also determine whether to open the first air damper or the second air damper based on the rotation direction of the drum 1, so that the airflow ejected from the first air outlet 531 or the second air outlet 532 can be blown more effectively onto the clothes in the drum 1, thereby achieving more thorough heat and moisture exchange with the clothes and improving drying efficiency.

[0083] Preferably, the step of "selectively opening the first damper or the second damper according to the rotation direction of the drum" specifically includes:

[0084] If the drum rotates from right to left, then open the first air damper;

[0085] If the drum rotates from left to right, then open the second air damper.

[0086] When the rotation direction of roller 1 is from right to left, from Figure 5 Viewed from above, the roller 1 rotates counterclockwise. The clothes in the roller 1 are attached to the right side wall of the roller 1. When the first air damper is opened, the airflow in the bypass pipe 51 is sprayed out from the first air outlet 531, which can blow onto the clothes located on the right side wall of the roller 1. In addition, the clothes are thrown down after the roller 1 rotates to the highest point or close to the highest point. Under the action of inertia, the clothes fall towards the lower left of the roller 1. During the fall, the clothes can also come into contact with the airflow sprayed from the first air outlet 531.

[0087] When the rotation direction of roller 1 is from left to right, from Figure 6Viewed from above, the drum 1 rotates clockwise. The clothes in the drum 1 are attached to the left side wall of the drum 1. When the second air door is opened, the airflow in the bypass pipe 51 is sprayed out from the second air outlet 532, which can blow onto the clothes located on the left side wall of the drum 1. In addition, the clothes are thrown down after the drum 1 rotates to the highest point or close to the highest point. Under the action of inertia, the clothes fall towards the lower right of the drum 1. During the fall, the clothes can also come into contact with the airflow sprayed from the second air outlet 532.

[0088] Preferably, the control method of the present invention further includes the following steps:

[0089] During the drying process, the humidity value in the drum is acquired;

[0090] The bypass component is selectively activated based on the humidity level.

[0091] In other words, when the drying mode is started, the bypass component is in the off state. During the drying mode, the humidity in drum 1 is detected, and the bypass component is activated based on the obtained humidity value. In this way, by determining the activation time of the bypass component based on the humidity value in drum 1, the bypass component is activated at the appropriate time, which is more conducive to improving drying efficiency and reducing drying time.

[0092] It should be noted that, in order to obtain the humidity in the drum 1, the humidity sensor can be installed on the support member 53, specifically at the position closest to the drum opening 11 of the drum 1, and the humidity sensor can be connected to the controller of the dryer so that the detected humidity data can be transmitted to the controller in a timely manner.

[0093] Preferably, the step of "selectively operating the bypass component according to the humidity value" specifically includes:

[0094] Compare the humidity value with the preset value;

[0095] If the humidity value is lower than the preset value, the bypass component will be activated.

[0096] In other words, the controller of the dryer has a preset value. After obtaining the humidity value in the drum 1, the humidity value is compared with the preset value. When the humidity value in the drum 1 is less than the preset value, it means that the humidity of the airflow discharged from the drum 1 is relatively low and the water content is low. At this time, the bypass component is activated, that is, the fan 52 is turned on, and part of the airflow in the circulating air duct 2 is sent back to the drum 1 to exchange heat and moisture with the clothes in the drum 1 again.

[0097] It should be noted that if the humidity value is not less than the preset value, the bypass component will not be activated.

[0098] When the humidity value in roller 1 is greater than or equal to the preset value, it indicates that the humidity of the airflow discharged from roller 1 is relatively high and the water content is high. At this time, it is not necessary to run the bypass component.

[0099] It should be noted that the present invention does not limit the specific value of the preset value. Those skilled in the art can flexibly set the specific value of the preset value based on experiments or experience in practical applications. For example, the preset value can be set to any value between 40% and 70%.

[0100] The control method of the present invention will be described in detail below with reference to a specific embodiment.

[0101] like Figure 8 As shown, the control method of the present invention includes the following steps:

[0102] S100: Obtain the humidity value in the drum.

[0103] During the drying mode, a humidity sensor detects the humidity value in drum 1 and feeds the humidity value back to the dryer's controller.

[0104] S200: Determines whether the humidity value is less than the preset value.

[0105] After receiving the humidity value, the controller compares the humidity value with the preset value to determine whether the humidity value is less than the preset value. If the result is yes, then step S300 is executed.

[0106] S300: Start the fan.

[0107] When the humidity value in the drum 1 is less than the preset value, the bypass component is activated, that is, the fan 52 of the bypass component is started, and a portion of the airflow entering the circulating air duct 2 is drawn into the bypass pipe 51.

[0108] S400: Obtain the rotation direction of the roller.

[0109] The decision to open the first or second air door depends on the rotation direction of drum 1. Specifically, if the drum rotates clockwise, step S500 is executed to open the second air door; conversely, if the drum rotates counterclockwise, step S600 is executed to open the first air door.

[0110] S500: Open the second air damper.

[0111] like Figure 6 As shown, when the drum 1 rotates clockwise, it is called the drum rotating in the forward direction. The second air damper is opened, and the airflow in the bypass pipe 51 is ejected from the second air outlet 532 and flows toward the left side wall of the drum 1.

[0112] S600: Open the first air damper.

[0113] like Figure 5 As shown, when the drum 1 rotates counterclockwise, it is called the drum reversal. The first air damper is opened, and the airflow in the bypass pipe 51 is ejected from the first air outlet 531 and flows toward the right side wall of the drum 1.

[0114] Finally, it should be noted that the dryer of the present invention has a controller configured to execute the control method described above.

[0115] Those skilled in the art will understand that although some embodiments described herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this application and form different embodiments. For example, any of the claimed embodiments in the claims of this application can be used in any combination.

[0116] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
