Description

Technical Field

[0001] This invention belongs to the field of clothing processing technology, and particularly relates to a clothing processing device and control method. Background Technology

[0002] During the drying process, clothes need to be constantly tumbled in the drum to ensure they are thoroughly dried. However, due to the combined effects of the weight of the clothes, the airflow speed, and the rotation of the drum, the clothes are prone to rolling into clumps or knots. This results in poor flatness, noticeable wrinkles, and shrinkage of the clothes after drying, leading to a poor user experience.

[0003] Current mainstream dryers typically have only one drying airflow circuit, and the problem of clothes tangling is usually improved by adjusting the forward and reverse rotation time of the drum; however, it cannot keep the clothes in a relaxed state as much as possible during the drying process, resulting in insufficient drying and low drying efficiency, and the clothes still have wrinkles after drying.

[0032] Compared with the prior art, the main advantages of the present invention are as follows:

[0033] The auxiliary drying airflow enters the drum through the auxiliary air duct, while the main drying airflow enters the drum through the main air duct. The velocity of the auxiliary drying airflow at the auxiliary air inlet is greater than that of the main drying airflow at the main air inlet, allowing the auxiliary drying airflow to initially flow in opposite directions to the main drying airflow before exiting through the air outlet. This opposing flow of the auxiliary and main drying airflows blows clothes near the drum opening towards the center of the drum, spreading them out, reducing and securing wrinkles, and preventing them from clumping together. The speed of the main fan and / or the auxiliary fan can be adjusted according to the position of the clothes inside the drum during the drying process, ensuring the clothes are fully spread out and in contact with the drying airflow under the action of the two airflows. This improves the matching degree between the spread surface area of ​​the clothes and the flow rate of the drying airflow, increasing drying efficiency and the smoothness of the clothes after drying. This addresses the problem that existing mainstream dryers cannot keep clothes in a fully spread state during the drying process, resulting in insufficient drying, low drying efficiency, and wrinkles remaining after drying. It also solves the problem that existing mainstream dryers cannot adjust the flow rate of the drying airflow according to the position of the clothes. Attached Figure Description

[0053] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention.

[0056] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0057] Current mainstream dryers typically have only one drying airflow circuit, and the problem of clothes tangling is usually improved by adjusting the forward and reverse rotation time of the drum; however, they cannot keep clothes in a relaxed state as much as possible during the drying and care process, resulting in insufficient drying and low drying efficiency, and wrinkles still remaining after the care is completed;

[0058] This invention creatively provides a garment processing device, including a drum and a drying assembly. The drum has a main air inlet, an auxiliary air inlet, and an air outlet. The drying assembly has a main air duct and an auxiliary air duct. The main air duct is connected between the main air inlet and the air outlet, and the main air duct also has an auxiliary air outlet. The auxiliary air duct is connected between the auxiliary air inlet and the auxiliary air outlet. The flow velocity of the auxiliary drying airflow at the auxiliary air inlet is greater than the flow velocity of the main drying airflow at the main air inlet, so that the auxiliary drying airflow can first flow in the opposite direction to the main drying airflow, and then be discharged through the air outlet along with the main drying airflow.

[0059] The auxiliary drying airflow can blow clothes near the drum opening towards the center of the drum, causing the clothes to unfold, reducing and fixing wrinkles, and preventing clothes from rolling into clumps. The speed of the main fan and / or the auxiliary fan can be adjusted according to the position of the clothes in the drum during the drying process, so that the clothes can be fully unfolded and in contact with the drying airflow under the action of the two drying airflows, improving the matching degree between the unfolded surface area of ​​the clothes and the flow rate of the drying airflow, improving drying efficiency and the smoothness of the clothes after drying and care.

[0060] <Clothing Processing Equipment>

[0061] like Figures 1a to 8 As shown, this embodiment provides a garment processing device, including:

[0062] The roller 1 includes a cylinder opening 13 and a cylinder wall. The cylinder wall includes a rear wall 11, which is located behind and opposite to the cylinder opening 13. One of the rear wall 11 and the cylinder opening 13 has a main air inlet 111, and the other has an auxiliary air inlet 231 and an air outlet 232. The roller 1 is rotatable. Preferably, the rear wall 11 has a main air inlet 111, and the cylinder opening 13 has an auxiliary air inlet 231 and an air outlet 232. The air outlet direction of the auxiliary air inlet 231 is towards the rear wall 11.

[0063] The drying assembly 2 has a main air duct and an auxiliary air duct 243. The main air duct is connected between the main air inlet 111 and the air outlet 232, and the main air duct also has an auxiliary air outlet 333. The auxiliary air duct 243 is connected between the auxiliary air inlet 231 and the auxiliary air outlet 333. A main fan 22 is installed on the main air duct, and an auxiliary fan 25 is installed on the auxiliary air duct 243.

[0064] The velocity of the auxiliary drying airflow at the auxiliary air inlet 231 is greater than the velocity of the main drying airflow at the main air inlet 111. When the auxiliary drying airflow and the main drying airflow enter the drum 1, the auxiliary drying airflow can first flow in the opposite direction to the main drying airflow, and then be discharged through the air outlet 232 with the main drying airflow. Preferably, the flow area of ​​the auxiliary air inlet is much smaller than that of the main air inlet, so that the velocity of the auxiliary drying airflow at the auxiliary air inlet 231 is much greater than the velocity of the main drying airflow at the main air inlet 111. The velocity of the auxiliary drying airflow at the auxiliary air inlet 231 is greater than 100 m / s.

[0065] Among them, the auxiliary drying airflow is the drying airflow that enters the drum 1 through the auxiliary air inlet 231, and the main drying airflow is the drying airflow that enters the drum 1 through the main air inlet 111.

[0066] When the auxiliary drying airflow flows in the opposite direction to the main drying airflow, it can blow clothes near the drum opening 13 towards the middle of the drum 1, causing the clothes to unfold, reducing and fixing the clothes, and preventing the clothes from rolling into clumps. The speed of the main fan 22 and / or the speed of the auxiliary fan 25 can be adjusted according to the position of the clothes in the drum 1 during the drying process, so that the clothes are fully unfolded and in a fluffy state under the action of the two drying airflows, and then fully contact the drying airflow, improving the matching degree between the unfolded surface area of ​​the clothes and the flow rate of the drying airflow, improving the drying efficiency and the smoothness of the clothes after drying and care. This solves the problem that existing mainstream dryers cannot keep the clothes in a fluffy state during the drying process, resulting in insufficient contact between the clothes and the drying airflow, incomplete drying, low drying efficiency, and wrinkles still remaining after drying. It also solves the problem that existing mainstream dryers cannot adjust the flow rate of the drying airflow according to the position of the clothes.

[0067] Preferably, the garment processing equipment is a dryer, especially a heat pump dryer; the garment processing equipment also includes a drum drive mechanism and a drum motor 41. The drum drive mechanism includes a first belt 431, a second belt 432, a first pulley 421, a second pulley 422, and a third pulley 423; the drum motor 41 and the first pulley 421 are driven together, the second pulley 422 and the third pulley 423 are coaxially arranged, the outer diameter of the second pulley 422 is smaller than the outer diameter of the third pulley 423, and the second pulley 422 is located at one axial end of the third pulley 423; the first pulley 421 and the second pulley 422 are connected by the first belt 431, and the third pulley 423 and the drum 1 are connected by the second belt 432; when the drum motor 41 is running, the drum 1 rotates under the action of the first belt 431 and the second belt 432; controlling the forward or reverse rotation of the drum motor 41 can make the drum 1 rotate in either direction.

[0068] The main air inlet 111 is located near the radial inner side of the rear wall 11 of the drum, and the air outlet direction of the main air inlet 111 is towards the drum opening 13; the drying assembly 2 includes a first housing 23, which has an auxiliary air inlet 231 and an air outlet 232; the auxiliary air inlet 231 is positioned higher than the air outlet 232; specifically, the first housing 23 has an annular structure surrounding the drum opening 13, the end of the annular structure near the drum opening 13 is sealed to the drum 1, and the end of the annular structure away from the drum opening 13 is tapered; the side wall of the annular structure has an auxiliary air inlet 231, and the radial bottom of the annular structure has an air outlet 232; the rear wall 11 of the drum includes multiple air inlet areas, which are spaced apart circumferentially along the rear wall 11 of the drum, and each air inlet area has multiple main air inlets 111;

[0069] The drum wall also includes the drum peripheral wall 12; the main drying airflow enters the drum 1 through multiple main air inlets 111 and flows toward the drum opening 13, and there is a gap between the main drying airflow and the drum peripheral wall 12;

[0070] The auxiliary air inlet 231 is located near the drum's peripheral wall 12. The auxiliary drying airflow entering the drum 1 through the auxiliary air inlet 231 first flows towards the rear wall 11 of the drum and close to the drum's peripheral wall 12, and then flows towards the drum opening 13 with the main drying airflow. The optimized design of the positions of the main air inlet 111 and the auxiliary air inlet 231, as well as the flow rates of the main and auxiliary drying airflows, ensures that the clothes are fully unfolded under the action of the main and auxiliary drying airflows, reducing the number and range of wrinkles. At the same time, the airflow and clothes are in full contact, improving drying efficiency and solving the problem of low drying efficiency caused by insufficient airflow. It also solves the problem of insufficient unfolding of clothes and uneven drying caused by unreasonable design of the main air inlet 111 and the auxiliary air inlet 231, which prevents the clothes from achieving the expected drying and care effect. Furthermore, it solves the problem of clothes easily rolling into clumps in the drum 1 and easily accumulating at the dryer door seal during the drying process.

[0071] To address the problem of high resistance in the drying airflow caused by an unreasonable main air duct structure design, this embodiment proposes that the main air duct includes a main air outlet duct, two chambers, and a main air inlet duct 211; two chambers are installed within the two chambers, and the two chambers and the compressor are connected via refrigerant pipes; the two chambers include an evaporator 341 and a condenser 342, where the evaporator 341 is used to dehumidify the drying airflow, and the condenser 342 is used to heat the drying airflow; the sidewalls of the two chambers form a two-chamber inlet 331, a two-chamber main outlet 332, and a two-chamber auxiliary outlet; the two-chamber auxiliary outlet is an auxiliary air outlet 333; preferably, the two-chamber main outlet 332 and the two-chamber auxiliary outlet are both located downstream of the condenser 342, so that the auxiliary drying airflow is dry hot air;

[0072] A main air outlet duct connects the inlet 331 and outlet 232 of the two chambers, and a main air inlet duct 211 connects the main outlet 332 and inlet 111 of the two chambers.

[0073] Specifically, the drying assembly 2 also includes a two-electrode box, which includes a two-electrode box body 31 and a two-electrode cover 32. The two-electrode box body 31 is fixedly installed, and the two-electrode cover 32 covers the two-electrode box body 31, forming a two-electrode cavity between the two-electrode cover 32 and the two-electrode box body 31. A two-electrode cavity inlet 331 is formed on the front side of the two-electrode cavity, and a two-electrode cavity main outlet 332 is formed on the rear side of the two-electrode cavity. An auxiliary outlet of the two-electrode cavity is formed on the left or right side of the two-electrode cavity. An evaporator 341 and a condenser 342 are sequentially arranged in the two-electrode cavity along the flow direction of the main drying airflow.

[0074] The first housing 23 also forms a first main air outlet 233, which is located at the bottom of the annular structure and the air inlet and air outlet 232 of the first main air outlet 233 are connected; the drying assembly 2 also includes a second housing 51, which is located at the bottom of the first main air outlet 233 and forms a second main air outlet 511; the second main air outlet 511 and the first main air outlet 233 are connected to form a main air outlet.

[0075] Regarding the issue of fixing the roller 1 and the two containers, this embodiment proposes that the axis of the roller 1 is along the horizontal direction, and the garment processing equipment also includes a chassis 5 and a support plate 63. The chassis 5 is located below the roller 1; the chassis 5 is provided with a two containers 31 or the chassis 5 and the two containers 31 are integrally formed; the chassis 5 is provided with a second shell 51 or the chassis 5 and the second shell 51 are integrally formed.

[0076] The support plate 63 is mounted on the chassis 5 and located on the rear side of the rear wall 11 of the drum; the drying assembly 2 also includes an air inlet shell 21, which is mounted on the support plate 63 and forms a main air inlet channel 211 between the air inlet shell 21 and the support plate 63; preferably, the air inlet shell 21 is located on one side of the support plate 63 and the drum 1 is located on the other side of the support plate 63; specifically, a second housing 51 is provided on the front side of the chassis 5, and the second housing 51 forms a second main air outlet channel 511, which includes a front air outlet 512, a rear air outlet 513, and a top air outlet 514 communicating with the second main air outlet channel 511; the first main air outlet The air outlet of the air duct 233 is connected to the top air outlet 514, and the rear air outlet 513 is connected to the inlet 331 of the two chambers. A front cover 61 is provided at the front air outlet 512 to seal the front air outlet 512. The second shell 51 also forms a heat dissipation channel 52. The air inlet of the heat dissipation channel 52 is close to the drum motor 41. A heat dissipation fan 62 is provided in the heat dissipation channel 52 for the heat dissipation of the drum motor 41. The support plate 63 forms multiple ventilation openings 631, and the multiple ventilation openings 631 and multiple air inlet areas are arranged one-to-one. The main drying airflow in the main air inlet duct 211 enters the drum 1 through the multiple ventilation openings 631 and the multiple main air inlets 111.

[0077] Furthermore, a main fan 22 is provided at one end of the main air inlet duct 211 near the two chambers. The main fan 22 connects the main air inlet duct 211 and the main outlet 332 of the two chambers. Under the action of the main fan 22, the drying airflow in the two chambers can enter the drum 1 through the main air inlet duct 211. Specifically, the main fan 22 includes a main fan blade 221 and a main motor 222. The main fan blade 221 is a centrifugal fan blade, and the main motor 222 is a DC motor. The air inlet shell 21 and the support plate 63 also form a main fan chamber, and the main fan blade 221 is rotatably arranged in the main fan chamber.

[0078] An auxiliary fan 25 is installed at one end of the auxiliary air duct 243 near the auxiliary air outlet 333. The auxiliary fan 25 connects the auxiliary air duct 243 and the auxiliary air outlet 333. The end of the auxiliary air duct 243 near the auxiliary air inlet 231 is tapered, which greatly reduces the cross-sectional area of ​​the auxiliary air inlet 231 (its cross-sectional area ≤ 500 mm^2) and increases the wind speed of the auxiliary air inlet 231. The wind speed of the auxiliary drying airflow at the auxiliary air inlet 231 is much greater than the flow speed of the main drying airflow at the main air inlet 111, causing the clothes located at the drum opening 13 to be blown open by the high-speed wind, and the wind in the middle of the drum 1 flows in a spiral shape.

[0079] The drying assembly 2 includes an auxiliary air duct shell 241 and an auxiliary air duct cover 242; the outer side wall of the two-piece housing 31 forms an installation structure 53; preferably, the installation structure is a groove, the auxiliary air duct shell 241 is mounted on the chassis 5 and embedded in the groove, providing space for the installation of the left and right side panels of the dryer's outer shell; the auxiliary air duct cover 242 covers the auxiliary air duct shell 241, and the auxiliary air duct cover 242 and the auxiliary air duct shell 241 form an auxiliary air duct 243; an auxiliary heating element 64 is provided in the auxiliary air duct 243 for heating the auxiliary drying air. The auxiliary fan 25 includes an auxiliary fan housing 251, an auxiliary fan cover 252, an auxiliary fan blade 253, and an auxiliary motor 254. The auxiliary fan housing 251 and the auxiliary fan cover 252 are fastened together to form an auxiliary fan cavity, which is connected to the auxiliary air duct 243 and the auxiliary air outlet 333. The auxiliary fan blade 253 is rotatably disposed inside the auxiliary fan cavity, and the auxiliary motor 254 is disposed outside the auxiliary fan cavity and is drivenly connected to the auxiliary fan blade 253. Preferably, the auxiliary air duct cover 242 and the auxiliary fan cover 252 are integrally formed.

[0080] To address the problem of clothing wrinkles failing to unfold when humidity is low, this embodiment proposes that an atomizer 351 be installed at one end of the auxiliary air duct 243 near the auxiliary air inlet 231. The atomizer 351 can generate atomized water droplets to moisten the auxiliary airflow. Specifically, the clothing processing equipment also includes a water box 353, which is located on the upper side of the roller 1. The water box 353 can store water, and the water box 353 and the atomizer 351 are connected by a water supply pipe 352. The water in the water box 353 can enter the atomizer 351 through the water supply pipe 352. Under the action of the atomizer 351, the water becomes atomized and mixes with the auxiliary drying airflow. It then comes into contact with the clothing along with the auxiliary drying airflow and moistens the clothing, preventing the clothing from shrinking and deforming severely due to excessively low humidity. The water box 353 has a water inlet, through which external water can be input into the water box 353, or condensate produced by the evaporator 341 can be input into the water box 353.

[0081] The garment handling equipment also includes a detection component and a controller. The detection component is located inside the annular structure and at the bottom of the annular structure. The detection component includes a first contact 65 and a second contact. The first contact 65 includes a first electrical connection end and a first contact end arranged opposite each other, and the second contact includes a second electrical connection end and a second contact end arranged opposite each other. Both the first and second electrical connection ends are electrically connected to the controller. The first and second contact ends can contact or separate, so that the detection circuit formed by the detection component and the controller is connected or disconnected, thereby determining the position of the garments in the drum. Preferably, the first contact 65 and the second contact are both metal sheets, and the first contact 65 is elastic. When the garments in the drum contact the first contact 65, the first and second contact ends contact each other, thereby connecting the detection circuit. When the garments separate from the first contact 65, the first and second contact ends separate under the action of elastic force, thereby disconnecting the detection circuit.

[0082] <Control Methods>

[0083] like Figure 9 As shown, this embodiment also provides a control method for a garment processing device, wherein the garment processing device is any of the garment processing devices described above, and the garment processing device is equipped with a drying program; when the garment processing device runs the drying program, the control method includes:

[0084] S1. Start the main fan 22 and obtain the current number of times the detection circuit is activated per unit time;

[0085] S2. Control the auxiliary fan 25 according to the current number of conduction cycles.

[0086] Furthermore, S2 includes:

[0087] S21. Compare the current number of times the signal is activated with the preset number of times;

[0088] S22. Adjust the speed of the auxiliary fan 25 based on the comparison between the current number of conductions and the preset number of conductions;

[0089] The more times the current conduction is performed, the higher the speed of the auxiliary fan 25.

[0090] Specifically, S22 includes:

[0091] When the current number of cycles is greater than the first preset number and less than the second preset number, or when the current number of cycles is equal to the first preset number, it is determined that the clothes have been blown to the drum opening 13 by the main drying airflow. The auxiliary fan 25 is then controlled to rotate at the first speed. The auxiliary drying airflow entering the drum 1 through the auxiliary air inlet 231 blows the clothes towards the middle of the drum 1. At the same time, with the cooperation of the large flow of the main drying airflow, the clothes can be spread out as much as possible inside the drum 1. Therefore, the clothes are easier to dry thoroughly and the drying efficiency is high.

[0092] When the current number of conduction cycles is greater than or equal to the second preset number of cycles, the auxiliary fan 25 is controlled to rotate at the second speed; it is determined that the filter screen at the air outlet 232 is blocked by lint, resulting in a decrease in the flow rate of the drying airflow. By increasing the wind speed of the auxiliary fan 25, the lint is separated from the filter screen, thereby increasing the flow rate of the drying airflow.

[0093] When the current number of conductions is less than or equal to the third preset number, control the auxiliary fan 25 to rotate at the third speed.

[0094] Among them, the third preset number of times is less than the first preset number of times, and the first preset number of times is less than the second preset number of times; specifically, the unit time is 1 minute, the first preset number of times is 15, the second preset number of times is 25, and the third preset number of times is 10; the third rotation speed is less than the first rotation speed, and the first rotation speed is less than the second rotation speed; preferably, the first rotation speed is n1, the second rotation speed is n2, and the third rotation speed is n3 = (n1 + n2) / 2.

[0095] In addition, control methods also include:

[0096] Obtain the on-resistance of the first contact 65 and the second contact;

[0097] Compare the on-resistance with the preset resistance;

[0098] When the on-resistance is less than or equal to the preset resistance, it indicates that the clothes are completely dried, and the main fan 22 and the auxiliary fan 25 are both stopped; otherwise, the auxiliary fan 25 rotates at the second speed until the clothes are completely dried.
