[0046] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as limiting the present application.

[0047] As shown in the background, the existing fabric treatment equipment brings convenience to people's life and reduces people's housework burden.

[0048] But in the process of treating fabric by using the fabric treatment cylinder in the fabric treatment equipment, the ozone generator in the fabric treatment equipment needs to be used, for example, the ozone generated by the ozone generator is used to disinfect and sterilize the fabric or to remove odor treatment, etc.

[0049] And the door seal of the clothes dryer is sealed by using materials such as felt, so that the sealing performance between the door seal and the fabric treatment cylinder, i.e. the drum, of the clothes dryer is poor. During the drying process of the fabric, slight gas leakage caused by poor sealing performance between the door seal and the drum will not affect the user, but during the process of using the ozone generator to perform the above treatment of the fabric, the leakage of ozone will affect the user, thereby reducing the safety factor of the user and affecting the user's experience of using the fabric treatment equipment.

[0050] To solve the above problems, an example embodiment of the present application provides a fabric treatment device 100. In the example, the fabric treatment device 100 includes a fabric treatment drum 110, an air inlet duct 120, an air outlet duct 130, a water treatment device, and a negative pressure assembly 150.

[0051] The fabric treatment drum 110 has a fabric treatment cavity 111. The air inlet 112 of the fabric treatment drum 110 is in communication with the air inlet duct 120, and the air outlet 113 of the fabric treatment drum 110 is in communication with the air outlet duct 130. The water treatment device is used to discharge or store the condensed water generated during the drying process. The negative pressure assembly 150 is configured to form an air duct between the air inlet duct 120 and the drain passage 140. The negative pressure assembly 150 is used to form a negative pressure environment at least partially at the position of the drum opening 114 adjacent to the fabric treatment drum 110 when the fabric treatment device 100 operates in the ozone mode, so as to guide part of the air from the air inlet duct 120 into the drain passage 140. That is, in the example, the air duct is formed by the negative pressure assembly 150, and based on the negative pressure environment formed at the position of the drum opening 114, the air containing ozone is discharged into the drain passage 140, so that the ozone is dissolved in the water, the leakage amount of ozone at the position of the drum opening 114 is reduced, and the user experience of the fabric treatment device 110 is improved.

[0052] Specifically, as shown in Figure 1 The fabric treatment device 100 includes the fabric treatment drum 110, the air inlet duct 120, the air outlet duct 130, the water treatment device, and the negative pressure assembly 150.

[0053] The fabric treatment device 100 can include but is not limited to a washing machine, which can include but is not limited to a washing and protecting all-in-one machine, a washing and drying all-in-one machine, and the like. For example, the washing machine can be a drum washing machine or an impeller washing machine with a drying function, and of course, the washing machine can also be other types of full-automatic washing machines.

[0054] Alternatively, the fabric treatment device 100 can also be a clothes dryer, which can include but is not limited to a direct exhaust type clothes dryer, a condensing type clothes dryer, or a heat pump type clothes dryer, and the like. In the example and the following examples, the fabric treatment device 100 is taken as a clothes dryer that adopts a drum for drying as an example for description.

[0055] The fabric treatment device 100 includes a housing 160, and the overall shape of the housing 160 can include but is not limited to a cuboid, a square, a cylinder, and the like. Alternatively, the shape of the front view of the housing 160 can also adopt a water drop shape or other shapes.

[0056] The shell 160 is hollow inside, and the hollow structure can be used to accommodate the fabric treatment drum 110, the air inlet duct 120, the air outlet duct 130, the water treatment device, the negative pressure assembly 150, etc. In addition, a drying module (not shown in the figure) for fabric drying can also be arranged in the shell 160.

[0057] The fabric treatment drum 110 is accommodated inside the shell 160 and is dried by rotation and cooperation with the drying air flow. The fabric treatment drum 110 has a fabric treatment cavity 111 for accommodating fabrics.

[0058] The fabric treatment drum 110 has a drum opening 114 on one side, through which the fabrics to be dried can be placed in the fabric treatment cavity 111 of the fabric treatment drum 110, or through which the dried fabrics can be taken out from the fabric treatment cavity 111 of the fabric treatment drum 110.

[0059] In one example, a plurality of lifting ribs (not shown in the figure) can also be arranged in the fabric treatment cavity 111 of the fabric treatment drum 110. The plurality of lifting ribs can be arranged in a circumferential array on the inner wall of the fabric treatment drum 110, and the two ends of each lifting rib point to the drum opening 114 and the bottom of the fabric treatment drum 110, respectively. That is, the lifting ribs are arranged along the length extension direction of the fabric treatment drum 110.

[0060] The lifting ribs can also be arranged in the form of a spiral line on the inner wall of the fabric treatment drum 110, or in the form of a wavy line on the inner wall of the fabric treatment drum 110.

[0061] The number of lifting ribs is at least two, that is, the number of lifting ribs can be two or more than two. It should be noted that the length of each lifting rib is not specifically limited, and the lengths of any two lifting ribs can be equal or not equal.

[0062] One end of the air inlet duct 120 is in communication with the air inlet of the fabric treatment drum 110, and the other end of the air inlet duct 120 can be in communication with one end of the air outlet duct 130, and the other end of the air outlet duct 130 is in communication with the air outlet of the fabric treatment drum 110. Based on this, the air outlet duct 130 cooperates with the air inlet duct 120 to form a circulating air path in communication with the fabric treatment cavity 111, so that the air can continuously circulate in the fabric treatment cavity 111 of the fabric treatment drum 110, thereby ensuring the drying treatment or other treatment (such as odor removal, disinfection and sterilization) of the fabrics, etc.

[0063] The air inlet duct 120 is used to introduce air from the outside or air treated in a specific way (such as heating, humidifying, adding ozone, etc.) into the fabric treatment cavity 111 of the fabric treatment drum 110, so as to treat the fabric with the air treated in the specific way, such as removing odor, disinfecting and sterilizing, drying the fabric, etc.

[0064] The water treatment device is used to discharge or store the condensed water generated in the drying process. During the treatment of the fabric, various fluids may be generated, such as sewage generated when the fabric is washed, or excess moisture exuded from the fabric during certain treatment processes, etc. The water treatment device can ensure that these fluids can be discharged in time, avoid accumulation in the fabric treatment cavity 111, thereby affecting the effect of fabric treatment, and also prevent the corrosion of the fluids to the internal structure of the fabric treatment drum 110, etc.

[0065] In addition, when the fabric treatment device 100 runs in the ozone mode, the water stored in the water treatment device can also be used to dissolve the ozone that is prone to leakage during a certain stage or the entire stage of the ozone mode, so as to prevent the ozone from leaking from the fabric treatment device 100.

[0066] The negative pressure assembly 150 is arranged to form an air duct between the air inlet duct 120 and the drainage channel 140, and the air volume in the air duct can be adjustable, so that the negative pressure assembly 150 can flexibly control the air volume in the air duct.

[0067] In addition, the negative pressure assembly 150 is used to form at least a partial negative pressure environment near the position of the drum opening 114 of the fabric treatment drum 110 when the fabric treatment device 100 runs in the ozone mode, so as to guide part of the air in the fabric treatment drum 110 into the water treatment device.

[0068] When the fabric treatment device 100 runs in the ozone mode to disinfect and sterilize or remove odor of the fabric, there is ozone in the air in the fabric treatment cavity 111 of the fabric treatment drum 110. Due to the poor sealing effect of the door seal at the position of the drum opening 114 of the fabric treatment drum 110, the air containing ozone in the fabric treatment cavity 111 may leak from the position of the door seal.

[0069] Therefore, in the ozone mode, some air containing ozone is present near the barrel mouth 114, and the negative pressure assembly 150 at least partially forms a negative pressure environment near the barrel mouth 114 of the fabric treatment barrel 110, so that part of the air in the fabric treatment barrel 110 is guided from the air inlet duct 120 into the water drainage channel 140, which can avoid the accumulation of ozone near the barrel mouth 114, reduce the risk of ozone leakage, and also help to discharge some products or residual substances that may react with ozone through the water treatment device, thereby improving the safety and effectiveness of the entire fabric treatment process. That is, the air containing ozone will be in contact with the water in the water treatment device, and the ozone in the air will dissolve in the water in the water treatment device, thereby reducing the leakage of ozone from the barrel mouth 114 position, thereby ensuring the safety factor of the operator using the fabric treatment equipment 100, and improving the user experience of the fabric treatment equipment 100.

[0070] As shown in Figure 1 In some embodiments, the negative pressure assembly 150 includes a first driving member 151 and an auxiliary air duct 152, and the auxiliary air duct 152 is used to connect other pipelines and has a flow guiding effect.

[0071] The auxiliary air duct 152 at least includes a first outlet in communication with the water drainage channel 140. The presence of the first outlet enables the auxiliary air duct 152 to be in contact with the water treatment device, thereby providing a channel basis for subsequent air introduction into the water treatment device.

[0072] The first driving member 151 is arranged at the connection position of the auxiliary air duct 152 and the air inlet duct 120, so that an air duct with adjustable air volume is formed in the auxiliary air duct 152. The first driving member 151 has a driving side and a conveying side. The driving side is arranged opposite to the inside of the fabric treatment barrel 110, so that the first driving member 151 can interact with the environment inside the fabric treatment barrel 110.

[0073] The conveying side is arranged opposite to the inlet end of the auxiliary air duct 152, so that the first driving member 151 can guide part of the air containing ozone in the fabric treatment barrel 110 to the conveying side, and then guide the part of the air containing ozone into the auxiliary air duct 152.

[0074] When the first driving member 151 works, the air flow in the fabric treatment cavity 111 can be guided by the barrel mouth 114 position of the fabric treatment barrel 110 into the auxiliary air duct 152, so that a negative pressure environment is at least partially formed near the barrel mouth 114 position of the fabric treatment barrel 110, and then under the guidance of the first driving member 151, part of the air containing ozone is guided into the auxiliary air duct 152, so that the part of the air in the fabric treatment barrel 110 is guided into the drainage channel 140, which can avoid the accumulation of ozone near the barrel mouth 114, reduce the risk of ozone leakage, and also help to discharge some products or residual substances that may react with ozone through the drainage channel 140, improve the safety and effectiveness of the entire fabric treatment process. That is, the air containing ozone will contact the water in the drainage channel 140, and the ozone in the part of the air will dissolve in the water in the drainage channel 140, thereby reducing the leakage of ozone from the barrel mouth 114 position, thereby ensuring the safety factor of the operator using the fabric treatment equipment 100, improving the user's experience of using the fabric treatment equipment 100, and ensuring the efficiency and safety of the fabric treatment process.

[0075] As shown in Figure 1 In some embodiments, a second driving member 121 and an ozone generator 122 are arranged on the air inlet duct 120, wherein the second driving member 121 can effectively control the air flow of the air entering the fabric treatment barrel 110.

[0076] Specifically, the second driving member 121 and the ozone generator 122 are arranged near the inlet end position of the air inlet duct 120.

[0077] Along the flow direction of the air in the air inlet duct 120, the second driving member 121 is located upstream of the ozone generator 122.

[0078] The ozone generator 122 is used to generate ozone gas to disinfect and sterilize the fabric in the fabric treatment cavity 111 or to remove odor.

[0079] Since the ozone gas has certain corrosive properties, the second driving member 121 is arranged upstream of the ozone generator 122 to avoid corrosion of the second driving member 121 by the ozone gas.

[0080] In addition, the second driving member 121 can adjust the flow rate and flow direction of the air, such as accelerating the air flow so that the air can more quickly converge with the ozone generated by the ozone generator 122, so that the ozone is fully mixed with the air by the rear end of the air inlet duct 120, and the ozone content in the air entering the fabric treatment cavity 111 is ensured to be within the set parameter range.

[0081] As shown in Figure 1As shown, in some embodiments, the air volume formed by the first driving member 151 is smaller than the air volume formed by the second driving member 121.

[0082] The first driving member 151 and the second driving member 121 have different functions in the whole fabric treatment device 100. The second driving member 121 is located on the air inlet duct 120 and upstream of the ozone generator 122, and its main function is to push air to flow to the ozone generator, and effectively control the air flow, flow rate and flow direction, etc. entering the ozone generator. Since it needs to ensure that enough air can stably enter the ozone generator 122 to generate ozone of appropriate concentration for treating the fabric in the fabric treatment chamber 111, and also needs to ensure that the air containing appropriate concentration of ozone enters the fabric treatment chamber 111 through the air inlet duct 120, a large air volume is required.

[0083] The first driving member 151 mainly functions at the connection position of the auxiliary air duct 152 and the air inlet duct 120, and its function is to guide the ozone-containing part of the air in the fabric treatment drum 110 to the conveying side, thereby guiding part of the air into the auxiliary air duct 152. In comparison, the air volume that the first driving member 151 needs to handle or the resistance that the first driving member 151 needs to overcome is smaller than that of the second driving member 121. For example, the first driving member 151 only guides the air flow related to the ozone-containing part of the air near the drum opening 114 in the fabric treatment drum 110, and does not need to push a large amount of air to flow in the air inlet duct 120 for a long distance like the second driving member 121, so the air volume formed by the first driving member 151 is smaller than the air volume formed by the second driving member 121.

[0084] However, it should be noted that although the air volume formed by the first driving member 151 is smaller than the air volume formed by the second driving member 121, the pressure formed by the air volume when the first driving member 151 operates is greater than the pressure required when ozone leaks at the door seal position in the original fabric treatment device 100. Based on this, it can be ensured that at least part of the air (containing ozone) located at the position of the drum opening 114 is guided into the drainage channel 140 through the auxiliary air duct 152, and the ozone in the part of the air is dissolved by the water in the drainage channel 140, thereby reducing the leakage of ozone from the position of the drum opening 114, thereby ensuring the safety factor of the operator using the fabric treatment device 100, improving the user's experience of using the fabric treatment device 100, and ensuring the efficiency and safety of the fabric treatment process.

[0085] Furthermore, the difference in airflow between the first drive unit 151 and the second drive unit 121 is to ensure the coordination of the entire fabric processing equipment 100 during operation. If the airflow generated by the first drive unit 151 is too large, it may interfere with the normal airflow established by the second drive unit 121 within the air inlet duct 120. For example, it could lead to inappropriate backflow or interfere with the normal air intake of the ozone generator 122. The smaller airflow generated by the first drive unit 151, while meeting its own functional requirements (guiding some air from the fabric processing cylinder 110 to the auxiliary duct 152), coordinates with the function of the second drive unit 121, allowing the airflow within the entire system to flow orderly in different areas according to their respective needs. This helps improve the efficiency and stability of the entire fabric processing equipment, ensuring the smooth operation of the fabric processing process while also reducing energy waste.

[0086] like Figure 1 As shown, in some embodiments, the first driving component 151 is a convection fan. The working principle of a convection fan is based on the phenomenon of air convection. When the convection fan rotates, the blades push the surrounding air molecules, causing airflow. Since a convection fan generates airflow by rotating its blades, different airflow characteristics will be produced depending on factors such as the shape, rotational speed, and tilt angle of the blades. For example, the shape design of the blades can affect the degree of airflow focusing and diffusion range, while the rotational speed directly relates to the airflow velocity and flow rate.

[0087] The rotating components of the convection fan can be driven by a motor to adjust the fan speed according to the needs of the fabric handling equipment 100, thereby precisely controlling the size and direction of the airflow it generates.

[0088] The drive side of the convection fan is positioned opposite the interior of the fabric processing cylinder 110. When the convection fan rotates, it can sense the air pressure and airflow conditions inside the fabric processing cylinder 110. The convection fan can effectively interact with the environment inside the fabric processing cylinder 110. For example, it can adjust its operating state based on the air pressure difference inside the fabric processing cylinder 110. If the air pressure inside the fabric processing cylinder 110 is high, the convection fan can enhance its ozone extraction capacity by appropriately increasing its speed, guiding the ozone to the conveying side, thereby guiding this portion of air into the auxiliary air duct 152. In this process, the airflow characteristics of the convection fan ensure that the ozone is effectively transferred. The relatively gentle airflow it generates avoids unnecessary disturbance to the fabric inside the fabric processing cylinder 110, while accurately guiding the ozone and related air to the target location, namely the drainage channel 140.

[0089] like Figure 1As shown, in some embodiments, the second drive component 121 includes an auxiliary fan. The auxiliary fan may include a motor, impeller, and housing. The motor is the core component providing power, used to drive the impeller to rotate. The shape, number, and angle of the impeller blades all affect the airflow characteristics generated by the fan; that is, the impeller can be flexibly designed according to the needs of the fabric processing cylinder 110 when processing the fabric.

[0090] An auxiliary fan is located on the air inlet duct 120 and upstream of the ozone generator 122. The auxiliary fan can regulate the airflow. In the fabric processing equipment 100, different processing needs may require different ozone concentrations, and ozone generation is closely related to the airflow entering the ozone generator 122. The auxiliary fan can precisely adjust the airflow upstream of the ozone generator 122 according to the settings of the fabric processing equipment 100 to ensure the generation of an appropriate ozone concentration.

[0091] Secondly, the auxiliary fan can also control the airflow rate. A suitable flow rate can ensure that the air flows evenly within the air inlet duct 120, avoiding situations where the local airflow is too fast or too slow. Even airflow helps to improve the working efficiency of the ozone generator 122, so that the large driving force of the auxiliary fan can ensure that a sufficient air source is provided for the entire fabric processing equipment 100.

[0092] In addition, the auxiliary fan can also cooperate with other parts such as the fabric processing cylinder 110 and the negative pressure component 150. For example, when the air pressure inside the fabric processing cylinder 110 changes, the auxiliary fan can adjust its working state according to the feedback information from the fabric processing equipment 100 to maintain the air pressure balance inside the entire fabric processing cylinder 110 and ensure the smooth progress of the fabric processing process.

[0093] like Figure 1 As shown, in some embodiments, the cross-sectional area of ​​the air inlet 112 of the fabric treatment tube 110 is larger than the cross-sectional area of ​​the air outlet 113 of the fabric treatment tube 110.

[0094] According to the principle of fluid continuity, under steady flow conditions, the flow rate of the fluid is conserved. That is, the flow rate at the air inlet 112 is equal to the flow rate at the air outlet 113. Flow rate equals velocity multiplied by cross-sectional area. When the cross-sectional area of ​​the air inlet is larger than that of the air outlet, in order to maintain a constant flow rate, the velocity at the air outlet 113 must be greater than that at the air inlet 112. Based on this, the air velocity within the fabric processing cylinder 110 can be controlled. Without the need for additional power equipment, the air velocity within the fabric processing cylinder 110 can be adjusted simply by designing the cross-sectional areas of the air inlet 112 and the air outlet 113.

[0095] In addition, when air flows from the larger cross-sectional area air inlet 112 to the smaller cross-sectional area air outlet 113, the air velocity increases and the pressure decreases. That is, the pressure at the air outlet 113 decreases. This helps the first drive member 151 to more effectively extract ozone-containing air near the air outlet 113 (i.e., near the cylinder opening 114).

[0096] Furthermore, the larger cross-sectional area of ​​the air inlet 112 ensures that enough air can enter the fabric treatment cylinder 110 at a lower air intake speed, effectively reducing noise during air intake and thus reducing energy consumption.

[0097] The large cross-sectional area of ​​the air inlet 112 provides relatively stable air intake conditions for the second drive component 121. The first drive component 151 and the second drive component 121 do not need to overcome excessive air intake resistance, thus allowing them to more effectively guide and drive the airflow. Meanwhile, the high-speed airflow generated by the small cross-sectional area of ​​the air outlet 113 can be utilized by the second drive component 121, facilitating the airflow to exit from the air outlet duct 130 for subsequent recycling.

[0098] like Figure 1 As shown, in some embodiments, the water treatment device is a drainage channel 140, which can be used to drain condensate generated during the drying process. Additionally, the drainage channel 140 can be used to discharge various fluids generated during fabric processing. For example, various fluids may be generated during fabric processing, such as wastewater generated during fabric washing, or excess water seeping from the fabric during certain processing steps. The drainage channel 140 ensures that these fluids can be discharged in a timely manner, preventing accumulation in the fabric processing chamber 111, which could affect the fabric processing effect. It also prevents adverse effects such as corrosion of the internal structure of the fabric processing cylinder 110 by the fluids. Furthermore, the air duct formed by the negative pressure component 150, based on the negative pressure environment created at the cylinder opening 114, discharges ozone-laden air into the drainage channel 140, causing the ozone to dissolve in the water. This reduces ozone leakage at the cylinder opening 114 and improves the user experience of the fabric processing equipment 110.

[0099] like Figure 1 As shown, in some embodiments, the water treatment device is a condensate box 170, which is located outside the circulating air duct and is used to store the condensate generated during the drying process. It should be noted that in ozone mode, the air duct formed by the negative pressure component 150, and the negative pressure environment created at the nozzle 114, discharges ozone-laden air into the condensate box 170, causing the ozone to dissolve in the water. This reduces ozone leakage at the nozzle 114 and improves the user experience of the fabric treatment equipment 110.

[0100] like Figure 1 As shown, in some embodiments, the water treatment device is a condensate box 170, which is located outside the circulating air duct and is used to store the condensate generated during the drying process.

[0101] A two-component box assembly 131 is provided on the air outlet duct 130. Specifically, the two-component box assembly 131 is located at the connection position between the air inlet duct 120 and the air outlet duct 130.

[0102] The two-component assembly 131 may be equipped with an evaporator and a condenser. The drying airflow for drying the fabric flows out of the air outlet duct 130 and passes through the two-component assembly 131. The evaporator can remove water from the drying airflow, and the condenser is used to heat the dried airflow after water removal. That is, the two-component assembly 131 is used to dehumidify and heat the humid air flowing through the air outlet duct.

[0103] After being dehumidified and heated by the two-stage air chamber assembly 131, the air enters the air inlet duct 120 under the drive of the second drive unit 121, and then mixes with the ozone generated in the ozone generator 122 before re-entering the fabric treatment tube 110.

[0104] Furthermore, the condensate generated during use by the two-piece container assembly 131 can first be collected in a drip tray below the assembly 131, and the drip tray is connected to the condensate box 170. That is, the drip tray is directly connected to the condensate box 170 through a condensate pipe (which can be the drain channel 140 in the example above). In other words, the condensate box is directly connected to the condensate pipe, and the condensate box 170 is located on the upper side of the fabric treatment cylinder 11.

[0105] The condensate flowing in the condensate pipe is discharged into the condensate box 170 by the first circulation pump 141. In order to facilitate the arrangement of components inside the housing 160, the two-piece box assembly 131 is located on the lower side of the fabric processing cylinder 110.

[0106] The connection point between the auxiliary air duct 152 and the air inlet duct 120 is higher than the connection point between the auxiliary air duct 152 and the condensate pipe. This effectively prevents condensate from entering the auxiliary air duct 152 under the influence of gravity, thus preventing backflow.

[0107] like Figure 2As shown, in some embodiments, the auxiliary air duct 152 may also have a second outlet, which is directly connected to the condensate box 170. A fan 190 is provided on the pipe 180 between the second outlet and the condensate box 170. The fan 190 is used to guide at least part of the air containing ozone in the fabric treatment cylinder 110 into the condensate box 170, so that the ozone can be dissolved by the condensate in the condensate box 170, thereby reducing the leakage of ozone from the cylinder opening 114. This ensures the safety factor of the operator when using the fabric treatment equipment 100, improves the user's experience of using the fabric treatment equipment 100, and ensures the efficiency and safety of the fabric treatment process.

[0108] Pipeline 180 has an opening and closing function; for example, a valve can be installed on pipeline 180. Fan 190 can be a gas flow pump.

[0109] In the above example, after the ozone generator 122 stops working, the convection fan can continue to be turned on to continuously reduce the ozone concentration in the fabric processing cylinder 110. When the ozone concentration drops below the safe value, the convection fan is turned off and the corresponding program of the fabric processing equipment 100 is ended, and the fabric can be taken out from the fabric processing cylinder 110.
