Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of household appliances, and particularly to a clothing care device. Background Art

[0002] With the improvement of people's living standards, users' requirements for the functional diversity and use convenience of clothing care devices are gradually increasing. For example, currently, users are no longer satisfied with the washing machine only providing a washing function, but also hope to enjoy additional functions such as drying and sterilization. This has led to the gradual development of existing washing machines towards all-in-one washing and drying machines, and all-in-one washing, drying, and sterilization machines.

[0003] In order to integrate multiple functions in one machine, the common practice in the current market is to use a double-tub washing machine, usually a combination of washing + drying, washing + washing, or washing + washing and drying. Generally speaking, the drying system of the double-tub washing machine only forms a working circuit with one of the two tubs. That is, the drying system can only provide a drying function for one of the tubs, and the other tub can only be used for single washing. If a sterilization function is to be added, an additional sterilization system is added on the basis of the original drying system and washing system. This sterilization system usually also only forms a working circuit with one of the two tubs.

[0004] It can be seen that, in essence, the existing multi-functional integrated cleaning device simply combines two independent washing machines and dryers into one machine, and the internal pipelines and the washing system, drying system, and sterilization system for realizing each function are independently arranged, resulting in a large overall machine volume and a complex internal structure. Summary of the Invention

[0005] An object of the embodiments of the present invention is to provide an improved clothing care device.

[0006] Therefore, the embodiments of the present invention provide a clothing care device, including: a box body defining a chamber; an air duct disposed in the box body and communicating with the chamber; further including: a drying module and an ozone generation module disposed in the air duct; a multi-channel module disposed in the air duct, the multi-channel module including a first channel and a second channel, a reducing agent box being disposed in the first channel; a switching component disposed in the multi-channel module, the switching component being movable between a plurality of positions to conduct one of the first channel and the second channel while blocking the other.

[0007] The drying system and the sterilization system of the existing clothing care device are independent of each other and are respectively equipped with independent circulation circuits, resulting in a large machine volume and a complex internal structure. In contrast, the present application can make the internal structure of the machine more compact and the machine volume smaller, saving the user's home space while ensuring the normal realization of each function. Specifically, the present application simplifies the internal structure by arranging the drying module and the ozone generation module in the same air duct and connecting the chamber, the drying module and the ozone generation module in series into a circulation circuit to share the air duct. Further, ozone itself has the antibacterial properties of being fast, efficient, and highly applicable. Using ozone for sterilization can effectively improve the antibacterial performance of the clothing care device. Considering that there may be excess ozone in the chamber, a reducing agent box is also provided in the circulation circuit in this embodiment to reduce the residual ozone blown out of the chamber, stabilize the ozone concentration in the chamber, and prevent the leakage of residual ozone outside the clothing care device to pollute the user's home environment and affect the user's health. Further, the switching component in the multi-channel module can control the gas in the air duct to pass through or bypass the reducing agent box when different functions are realized. For example, when the drying function is realized, the switching component can make the gas flow through the second channel to bypass the reducing agent box; when the sterilization function is realized, the switching component can make the gas flow through the first channel to pass through the reducing agent box to form a circulation circuit. Optionally, the drying module is connected to the air inlet of the multi-channel module, and the ozone generation module is connected to the air outlet of the multi-channel module; or, the drying module and the ozone generation module are connected in series to the air outlet of the multi-channel module. Thus, the drying module, the ozone generation module, and the multi-channel module can share the same circulation circuit, making the internal structure of the machine more compact and the space utilization rate higher.

[0008] Optionally, the air outlet includes a first air outlet communicating with the first channel and a second air outlet communicating with the second channel, and the ozone generation module is connected to the first air outlet. Thus, the reducing agent box in the first channel can be connected to the circulation circuit together with the ozone generation module. Specifically, the ozone generated by the ozone generation module can flow into the chamber along with the gas in the air duct, play a sterilization role, and then flow into the first channel of the multi-channel module. The ozone in the gas can be absorbed and reduced by the reducing agent box provided in the first channel to stabilize the ozone concentration in the chamber and prevent ozone leakage and pollution of the user's home environment.

[0009] Optionally, the multi-channel module includes: a main body portion having independent first and second chambers. The first chamber is adapted to form the first channel, the second chamber is adapted to form the second channel, and the first and second chambers are separated by a partition. Thus, through the separation of the partition, it can be ensured that the first and second chambers are independent of each other, preventing gas from leaking or diffusing to the other channel when flowing through the first or second channel.

[0010] Optionally, the reducing agent box is detachably accommodated in the first chamber, so that the reducing agent box can be taken out separately, and the reducing agent box and the reducing agent inside the reducing agent box can be replaced regularly to ensure better reducing performance.

[0011] Optionally, along the flow direction of the gas in the air duct, the main body has a relative front wall and rear wall, the air inlet is opened in the front wall, and the air outlet is opened in the rear wall. As a result, the flow direction of the gas in the main body is roughly consistent with the flow direction in the entire air duct, so that the gas can pass through the main body efficiently and quickly, thereby improving the gas flow efficiency in the circulation loop. Furthermore, after the gas enters the multi-channel module, it can flow from one end of the first channel or the second channel along its extension direction to the other end, and the internal space utilization rate of the multi-channel module is high. Furthermore, when the first channel is turned on, the contact time between the gas and the reducing agent box arranged in the first channel can also be increased to fully reduce the residual ozone in the gas.

[0012] Optionally, the first cavity and the second cavity are arranged side by side in a first plane, wherein the first plane is perpendicular to the flow direction of the gas in the air duct. Thus, the internal structure of the multi-channel module can be simplified, making the manufacturing process of the multi-channel module simpler.

[0013] Optionally, the volumes of the first chamber and the second chamber are equal. Thus, the sizes of the two chambers are ensured to be sufficient to obtain a better gas flow efficiency. Furthermore, the second chamber may also contain other functional components of similar volume to the reducing agent box, such as a deodorant box or a fragrance box, to add fragrance to the clothes in the chamber. Furthermore, the equal volumes of the first chamber and the second chamber can also make the appearance of the multi-channel module regular, which is convenient for production and assembly.

[0014] Optionally, the main body includes: a box body, including a bottom wall, a front wall, a rear wall and a pair of side walls, the partition is located between the pair of side walls, the bottom wall, the front wall, the rear wall, one of the pair of side walls and the partition together form the first cavity opening upward, and the bottom wall, the front wall, the rear wall, the other of the pair of side walls and the partition together form the second cavity opening upward; a top cover for closing the opening; a first sealing structure, located between the box body and the top cover, and arranged around the opening. Thus, the top cover is detachable, which is convenient for replacing the components placed in the main body, such as the reducing agent box. Further, the first sealing structure is arranged at the connection between the box body and the top cover, which can ensure the airtightness of the main body. Further, the first sealing structure can also improve the sealing performance between the first cavity and the second cavity, and prevent the gas flowing through one of the first channel and the second channel from leaking and diffusing to the other one.

[0015] Optionally, the box body includes: a main body having an open front end along the gas flow direction in the air duct; a front cover for closing at least a part of the open end, and the front cover is adapted to form the front wall. Thus, the front cover of the box body is also detachable, facilitating the opening or closing of the first chamber and the second chamber, and further making it more convenient to disassemble and replace the components disposed in the box body.

[0016] Optionally, the switching component includes: a plate portion movable between the plurality of positions to conduct one of the first channel and the second channel while blocking the other; a driving portion for driving the movement of the plate portion. Thus, the driving portion can drive the plate portion to block the first channel or the second channel while conducting the other channel. In other words, when implementing different functions, the switching component can conveniently and quickly control the access of the first channel or the second channel to the circulation loop by driving the plate portion. Further, the plate portion and the driving portion have low manufacturing costs and are easy to implement, which is beneficial to reducing the production and manufacturing costs.

[0017] Optionally, the driving portion includes: a motor; a rotating shaft connected to the output shaft of the motor, and the plate portion is connected to the rotating shaft and can rotate with the rotating shaft. Thus, the motor can drive the rotating shaft to rotate, and further drive the plate portion to rotate to conduct one of the first channel and the second channel while blocking the other. Further, the control method of driving the plate portion to rotate by the motor is easy to implement, which is beneficial to reducing the production and manufacturing costs.

[0018] Optionally, the axial direction of the rotating shaft is parallel to the gas flow direction in the air duct, or the axial direction of the rotating shaft, the gas flow direction in the air duct, and the direction from the first channel to the second channel are perpendicular to each other in pairs. Thus, the plate portion moves to the front of the first channel or the second channel along the gas flow direction by rotation to close the first chamber or the second chamber and prevent the air flow from flowing through the first channel or the second channel. Further, when the axial direction of the rotating shaft is parallel to the gas flow direction, the plate portion can be disposed at a position close to the air inlet, thereby shortening the length of the multi-channel module along the gas flow direction and further reducing the size of the multi-channel module.

[0019] Optionally, the driving portion includes: a motor; a driving rod connected to the output shaft of the motor, and the plate portion can perform a reciprocating movement under the push of the driving rod. Thus, the plate portion can be driven by the motor and the driving rod to reciprocate in the direction from the first channel to the second channel in a first plane (a plane perpendicular to the gas flow direction) to conduct one of the first channel and the second channel while blocking the other. Further, the plate portion only needs to move in the first plane, which can also avoid wasting the space inside the multi-channel module and improve the space utilization rate.

[0020] Optionally, the clothing care device further includes: a second sealing structure disposed around the edge of the plate portion. Thus, the second sealing structure can further seal the gap between the plate portion and the wall of the first chamber or the second chamber, improve the sealing effect, and prevent gas leakage.

[0021] Optionally, at least one side surface of the reducing agent cartridge is provided with a vent hole communicating with the interior. Thus, gas can flow into the reducing agent cartridge from the vent hole, and then come into full contact with the reducing agent in the cartridge to ensure that the ozone in the gas is fully adsorbed and reduced.

[0022] Optionally, the clothing care device further includes: a blower device disposed in the air duct, and the blower device is used to promote the gas flow in the air duct. Thus, the blower device can increase the gas flow rate in the air duct and further improve the drying or disinfection efficiency. Further, the blower device can also be used to provide the gas flow rate and flow direction in the air duct.

[0023] Optionally, along the gas flow direction in the air duct, the blower device is located upstream of the drying module. Thus, the blower device can blow the gas towards the drying module, and the heated gas enters the chamber to achieve drying.

[0024] Optionally, the clothing care device further includes: a condensation device disposed on the air duct for heat exchange with the gas flowing in the air duct. Thus, through heat exchange, the temperature of the humid gas in the air duct is reduced to make it saturated cold air. Further, the water vapor in the gas condenses into liquid water and separates from the gas due to the temperature reduction, thereby reducing the humidity of the gas.

[0025] Optionally, along the gas flow direction in the air duct, the condensation device is located between the chamber and the drying module. Thus, when the drying function is executed, after the gas is heated by the drying module, it enters the chamber to dry the clothes to be dried in the chamber. Then, the humid gas dried from the clothes is condensed by the condensation device to liquefy the water vapor and reduce the gas humidity to become saturated cold gas. Then, it is heated by the drying module again to become dry hot gas. The dry hot gas contacts the clothes to be dried in the chamber, becomes humid gas, and enters the condenser, and so on in a cycle to achieve the drying function.

[0026] Optionally, the multiple positions at least include: a first position, when the switching component moves to the first position, the first channel is conducted and the second channel is blocked; and a second position, when the switching component moves to the second position, the first channel is blocked and the second channel is conducted. Thus, by changing the position of the switching component between the first position and the second position, the gas flow path is changed, enabling the gas to flow into the first channel or the second channel. In other words, when implementing the sterilization or drying function, the movement and switching of the switching component can cause the gas to pass through or bypass the reducing agent cartridge.

[0027] Optionally, the clothing care device further includes: a control module configured to selectively execute a drying program or a sterilization program. When the drying program is executed, the control module controls the drying module to operate, the switching component moves to the second position, and the ozone generation module is in a non-operating state; when the sterilization program is executed, the control module controls the ozone generation module to operate, the switching component moves to the first position, and the drying module is in a non-operating state. Thus, when the drying program is executed, the control module controls the drying module and the condensing device to perform condensing drying on the clothes to be dried in the chamber. At the same time, the switching component conducts the second channel and blocks the first channel. When the sterilization program is executed, the ozone generation module releases ozone to sterilize the clothes in the chamber. At the same time, the switching component conducts the first channel and blocks the second channel. Further, when the gas flows through the first channel, it passes through the reducing agent cartridge provided in the first channel, so that the ozone in the gas is reduced and absorbed by the reducing agent, to stabilize the ozone concentration in the chamber and prevent ozone leakage from polluting the user's home environment.

[0028] Optionally, the chamber includes a first chamber and a second chamber, and the first chamber and the second chamber are respectively connected to the air duct in parallel. Thus, the first chamber and the second chamber can be simultaneously connected to the circulation loop, and the clothes in the two chambers can be dried or sterilized simultaneously, improving the overall working efficiency of the clothing care device and enabling the clothing care device to achieve a double-tub drying or double-tub sterilization mode.

Detailed implementation manners

[0039] As described in the background art, existing clothing care devices usually simply combine two mutually independent washing machines and dryers into one machine, and the internal pipelines and the washing system, drying system, and sterilization system for realizing various functions are independently arranged, resulting in a large overall machine volume and a complex internal structure.

[0040] To solve the above technical problems, an embodiment of the present invention provides a clothing care device, comprising: a box body defining a chamber; an air duct disposed in the box body and communicating with the chamber; further comprising: a drying module and an ozone generation module disposed in the air duct; a multi-channel module disposed in the air duct, the multi-channel module including a first channel and a second channel, and a reducing agent box is disposed in the first channel; a switching member disposed in the multi-channel module, the switching member being movable between a plurality of positions to enable one of the first channel and the second channel to be conducted while the other is blocked.

[0041] In this application, by disposing the drying module and the ozone generation module in the same air duct, the chamber, the drying module and the ozone generation module are connected in series to form a circulation loop, sharing the air duct, which simplifies the internal structure. Further, ozone itself has fast, efficient and strong applicability in sterilization performance. Using ozone for sterilization can effectively improve the sterilization performance of the clothing care device. Considering that there may be excess ozone in the chamber, therefore, in this embodiment, a reducing agent box is also provided in the circulation loop to reduce the residual ozone blown out of the chamber, stabilize the ozone concentration in the chamber, and avoid the leakage of residual ozone outside the clothing care device to pollute the user's home environment and affect the user's health. Further, the switching member in the multi-channel module can control the gas in the air duct to pass through or bypass the reducing agent box when different functions are realized. For example, when the drying function is realized, the switching member can make the gas flow through the second channel to bypass the reducing agent box; when the sterilization function is realized, the switching member can make the gas flow through the first channel to pass through the reducing agent box to form a circulation loop. Thus, this embodiment can make the internal structure of the machine more compact and the volume of the machine smaller, saving the user's home space on the premise of ensuring the normal realization of each function.

[0042] To make the above objects, features and advantages of the present invention more obvious and understandable, the following specifically describes the specific embodiments of the present invention with reference to the drawings.

[0043] Figure 1 It is a schematic diagram of a clothing care device 1 according to an embodiment of the present invention; Figure 2 is Figure 1 A schematic diagram of the clothing care device 1 shown in the embodiment when the drying function is realized; Figure 3 is Figure 1 A schematic diagram of the clothing care device 1 shown in the embodiment when the sterilization function is realized.

[0044] In this embodiment, the clothing care device 1 may have a depth direction, a width direction, and a height direction that are perpendicular to each other in pairs. The left-right direction may be parallel to the width direction, the front-back direction may be parallel to the depth direction, and the up-down direction may be parallel to the height direction. Among them, the front or the front side refers to the direction facing the user when the clothing care device 1 is in use, and the rear or the rear side refers to the direction away from the user when the clothing care device 1 is in use.

[0045] Specifically, the clothing care device 1 described in this embodiment includes: a box body 10 that defines a chamber 11. The clothing care device 1 may be, for example, a dryer, a washing and drying machine, or a double-tub washing and drying integrated machine. The chamber 11 is adapted to accommodate clothes to be processed, and the clothes to be processed may include clothes to be dried or clothes to be sterilized.

[0046] Furthermore, the number of the chambers 11 may be one, two, or more. For an embodiment with only one chamber 11, the clothing care device 1 may be a device with a drying function, such as a pure dryer, or a washing and drying machine. For an embodiment with two chambers 11, at least one of the two chambers 11 has a drying function, and the other may only have a washing function. Further, both of the two chambers 11 may have a sterilization function.

[0047] Furthermore, the clothing care device 1 may further include: an air duct 12 disposed in the box body 10 and communicating with the chamber 11. Thus, through the connection of the air duct 12, the gas in the box body 10 can form a circulation loop. By applying different treatments (such as heating, increasing the ozone concentration, etc.) to the circulating gas, the clothing care device 1 can achieve different functions. The circulation loop may be a loop formed by the gas circulating in the air duct 12 and the chamber 11, as shown by the arrowed lines in Figure 2 and Figure 3 as shown.

[0048] Furthermore, the clothing care device 1 further includes: a drying module 13 and an ozone generation module 14 disposed in the air duct 12. Thus, when realizing the drying function or the sterilization function, the dry and hot gas generated after being heated by the drying module 13 or the sterilization gas mixed with ozone after passing through the ozone generation module 14 can both circulate back and forth in the box body 10 through the air duct 12 to achieve the corresponding function. Further, the drying module 13 and the ozone generation module 14 are disposed in the same air duct 12. When realizing the drying or sterilization function, the gas circulates in the same air duct 12, which can save the air duct 12 and simplify the internal structure of the box body 10.

[0049] In some embodiments, the ozone generation module 14 is used to generate ozone. The ozone enters the chamber 11 along with the gas flowing in the air duct 12 and contacts the clothes to be sterilized placed in the chamber 11, playing a role in sterilization. Specifically, ozone sterilization can be a bacteriolysis-level method, which has the advantages of thorough sterilization, no residue, and broad-spectrum sterilization. In practical applications, if ozone leaks in the clothing care device 1, resulting in a relatively high ozone concentration in the environment, it may cause harm to the human body, such as the respiratory system, blood circulation system, and nervous system, etc. Therefore, the present embodiment further sets corresponding adsorption and reduction modules (for example, the reducing agent cartridge 153, as shown in Figure 5 ), in the circulation loop to stabilize the ozone concentration in the chamber 11 and avoid ozone leakage.

[0050] Furthermore, the clothing care device 1 further includes: a multi-channel module 15 disposed in the air duct 12. The multi-channel module 15 includes a first channel 151 and a second channel 152. A reducing agent cartridge 153 is disposed in the first channel 151; a switching member 16 is disposed on the multi-channel module 15. The switching member 16 can move between multiple positions to conduct one of the first channel 151 and the second channel 152, while blocking the other.

[0051] For the convenience of description, hereinafter, the width direction of the multi-channel module 15 is denoted as the x direction, the depth direction of the multi-channel module 15 is denoted as the y direction, and the height direction of the multi-channel module 15 is denoted as the z direction. The upstream refers to the side where the gas passes first in the gas flow direction; the downstream refers to the side where the gas passes later in the gas flow direction. In some embodiments, the x direction can be parallel to the width direction of the clothing care device 1, the y direction can be parallel to the depth direction of the clothing care device 1, and the z direction can be parallel to the height direction of the clothing care device 1. In some embodiments, the specific setting angle of the multi-channel module 15 in the clothing care device 1 can be flexibly adjusted as needed to make full use of the space in the clothing care device 1, which is beneficial to achieving a compact design.

[0052] In a specific embodiment, as shown in Figure 2 and Figure 3 , the multi-channel module 15 includes two channels, for example, a first channel 151 and a second channel 152. The switching member 16 disposed in the multi-channel module 15 can conduct the first channel 151 or the second channel 152, while blocking the other channel, so that when different functions are realized in the clothing care device 1, the gas in the circulation loop mainly flows through the conducted channel among the first channel 151 and the second channel 152.

[0053] For example, in Figure 2In the scenario where the drying function is implemented, the switching component 16 conducts the second channel 152 of the multi-channel module 15 and blocks the first channel 151 at the same time. Further, the dry and hot gas generated by heating of the drying module 13 flows through the second channel 152 and then enters the chamber 11 to dry the clothes to be dried.

[0054] In Figure 3 In the scenario where the sterilization function is implemented, the switching component 16 conducts the first channel 151 of the multi-channel module 15 and blocks the second channel 152 at the same time. Further, the ozone released by the ozone generation module 14 enters the chamber 11 along with the gas flowing in the circulation loop to sterilize the clothes. Further, the gas flowing out of the chamber 11 flows into the first channel 151 of the multi-channel module 15. In the first channel 151, the ozone in the gas passes through the reducing agent box 153 provided in the first channel 151 and reacts fully with the internal reducing agent and then is reduced and absorbed to stabilize the ozone concentration in the chamber 11 and avoid leakage when the user takes out the clothes after residual ozone remains in the chamber 11 or on the clothes.

[0055] As above, compared with the existing drying system and sterilization system of the clothing care device 1 being independent of each other and each being configured with an independent circulation loop, resulting in a large machine volume and a complex internal structure, this implementation can make the structure more compact and the overall size of the machine smaller. Specifically, in this implementation, by arranging the drying module 13 and the ozone generation module 14 in the same air duct 12, the chamber 11, the drying module 13 and the ozone generation module 14 are connected in series into a circulation loop and share the air duct 12, simplifying the internal structure. Further, ozone itself has fast, efficient and strong applicability sterilization performance, and using ozone for sterilization can effectively improve the sterilization performance of the clothing care device 1. Considering that there may be excess ozone in the chamber 11, therefore, this implementation also sets a reducing agent box 153 in the circulation loop to reduce the residual ozone blown out of the chamber 11 and stabilize the ozone concentration in the chamber 11, avoiding the leakage of the residual ozone outside the clothing care device to pollute the user's home environment and affect the user's health. Further, the switching component 16 in the multi-channel module 15 can control the gas in the air duct 12 to pass through or avoid the reducing agent box 153 when different functions are realized. For example, when the drying function is realized, the switching component 16 can make the gas flow through the second channel 152 to avoid the reducing agent box 153; when the sterilization function is realized, the switching component 16 can make the gas flow through the first channel 151 to pass through the reducing agent box 153 to form a circulation loop. Thus, this implementation can make the internal structure of the machine more compact and the machine volume smaller while ensuring the normal realization of each function, saving the user's home space.

[0056] In a specific implementation, the multiple positions at least include: a first position. When the switching component 16 moves to the first position, the first channel 151 is conducted, and the second channel 152 is blocked; and a second position. When the switching component 16 moves to the second position, the first channel 151 is blocked, and the second channel 152 is conducted. Thus, by changing the position of the switching component 16 between the first position and the second position, the gas flow path is changed, so that the gas flows into the first channel 151 or the second channel 152. In other words, when implementing the sterilization or drying function, the movement and switching of the switching component 16 can make the gas pass through or avoid the reducing agent cartridge 153.

[0057] Specifically, in combination with Figure 3 , when the switching component 16 moves to the first position, the second channel 152 is blocked, the gas flows into the first channel 151, and flows through the reducing agent cartridge 153. After the adsorption and reduction of the reducing agent, the ozone in the gas is removed. Further, the gas flowing out of the first channel 151 continues to flow to the ozone generation module 14 to complete the cycle.

[0058] In combination with Figure 2 , when the switching component 16 moves to the second position, the first channel 151 is blocked, the gas flows into the second channel 152 to avoid the reducing agent cartridge 153. After the gas flows out of the second channel 152, it directly enters the air duct 12 and continues to circulate.

[0059] In a specific implementation, continue to refer to Figure 2 and Figure 3 , the drying module 13 can be connected to the air inlet 157 of the multi-channel module 15 (as shown in Figure 4 ), and the ozone generation module 14 is connected to the air outlet 158 of the multi-channel module 15.

[0060] Specifically, the air outlet 158 can include an independent first air outlet 158a and a second air outlet 158b. Among them, the first air outlet 158a is communicated with the ozone generation module 14, and the second air outlet 158b is communicated with the drying module 13. In some embodiments, the drying module 13 can be arranged upstream of the multi-channel module 15 along the gas flow direction. In the air duct 12, the gas first flows through the drying module 13 and is heated. The heated dry and hot gas flows into the multi-channel module 15 from the air inlet 157. Specifically, it flows through the second channel 152, and then flows out from the second air outlet 158b of the multi-channel module 15 (refer to Figure 4 ), and then flows into the chamber 11 to implement the drying function, and then flows back to the drying module 13 to circulate in this way.

[0061] Further, the ozone generation module 14 can be arranged downstream of the multi-channel module 15 along the gas flow direction. Specifically, after the gas passing through the multi-channel module 15 flows out from the first air outlet 158a, it will further flow through the ozone generation module 14 along the air duct 12. When implementing the sterilization function, the ozone generation module 14 is in an operating state and continuously releases ozone into the air duct 12. After the gas mixed with ozone enters the chamber 11 to play a sterilization role, it flows into the multi-channel module 15 again. Specifically, it flows into the first channel 151. At this time, the ozone in the gas is reduced and absorbed by the reducing agent arranged in the first channel 151, and this cycle repeats.

[0062] In a variant, the drying module 13 and the ozone generation module 14 can be connected in series to the air outlet 158 of the multi-channel module 15. Thus, the drying module 13, the ozone generation module 14, and the multi-channel module 15 can share the same circulation loop, making the internal structure of the machine more compact and the space utilization rate higher.

[0063] Specifically, the drying module 13 and the ozone generation module 14 can also be connected in series downstream of the multi-channel module 15 along the gas flow direction. Since when implementing different functions, the ozone generation module 14 is in an operating or non-operating state. For example, when implementing the drying function, the ozone generation module 14 is in a non-operating state, and the gas flowing through the ozone generation module 14 will not carry ozone into the chamber 11; when implementing the sterilization function, the ozone generation module 14 is in an operating state. Therefore, even if the drying module 13 and the ozone generation module 14 are arranged in series in the air duct 12, they will not cause adverse effects on each other and affect the normal implementation of the drying or sterilization function.

[0064] In some embodiments, when implementing the sterilization function, the drying module 13 can also be in an operating state. The increase in gas temperature can accelerate the processes of ozone sterilization and ozone reduction, improving the overall operating efficiency.

[0065] Figure 4 is a schematic diagram of a multi-channel module 15 according to an embodiment of the present invention; Figure 5 is Figure 4 an exploded view of the shown structure; Figure 6 is Figure 4 a schematic diagram of the shown structure after removing the top cover 154a; Figure 7 is a cross-sectional view along the A-A direction when the switching component 16 is in the second position Figure 4 ; Figure 8 is a perspective view along the A-A direction when the switching component 16 is in the first position Figure 4 ;

[0066] In some embodiments, such as Figure 4As shown, the air outlet 158 includes a first air outlet 158a communicating with the first channel 151 and a second air outlet 158b communicating with the second channel 152, and the ozone generation module 14 is connected to the first air outlet 158a. Thus, the reducing agent cartridge 153 disposed in the first channel 151 can be simultaneously connected to the ozone generation module 14 in the circulation loop. Specifically, the ozone generated by the ozone generation module 14 can flow into the chamber 11 as a disinfectant along with the gas in the air duct 12. After playing the disinfection role, it flows into the first channel 151. The ozone in the gas can be absorbed and reduced by the reducing agent cartridge 153 disposed in the first channel 151 to stabilize the ozone concentration in the chamber 11 and avoid ozone leakage and pollution of the user's home environment.

[0067] Specifically, in combination with Figure 3 , when the ozone generation module 14 is operating, the switching component 16 conducts the first channel 151 and blocks the second channel 152 at the same time, so that in the disinfection mode, the gas in the circulation loop passes through the ozone generation module 14, the chamber 11 and the reducing agent cartridge 153 in sequence. After flowing out from the first air outlet 158a of the multi-channel module 15, it continues to circulate. Thus, the reducing agent cartridge 153 can stabilize the ozone concentration in the chamber 11. While realizing the disinfection function, it can also avoid ozone leakage.

[0068] In some embodiments, with reference to Figures 4 to 8 , the multi-channel module 15 may include: a main body portion 154 having independent first and second chambers 155 and 156. The first chamber 155 is adapted to form the first channel 151, and the second chamber 156 is adapted to form the second channel 152. The first chamber 155 and the second chamber 156 are separated by a partition 159. Thus, through the separation of the partition 159, it can be ensured that the first chamber 155 and the second chamber 156 are independent of each other, and leakage and diffusion to another channel can be avoided when the gas flows through the first channel 151 or the second channel 152.

[0069] In a preferred embodiment, the partition 159 and the main body portion 154 can be made of high-stability and heat-resistant materials to avoid corrosion and damage to the results caused by strongly oxidizing mixed gases or high-temperature gases when realizing the disinfection function or the drying function. Further, the inner wall of the air duct 12 can also be made of high-stability and heat-resistant materials to increase the service life of the internal structure of the clothing care device 1.

[0070] Further, the reducing agent cartridge 153 is detachably accommodated in the first chamber 155. Thus, the reducing agent cartridge 153 can be taken out separately, and the reducing agent cartridge 153 and the reducing agent inside it can be replaced regularly to ensure better reduction performance.

[0071] In some embodiments, the reducing agent may be, for example, activated carbon. Activated carbon is placed in the reducing agent box 153 in powder, granular or block form, which can increase the contact area between the gas and the activated carbon and enhance the reducing effect. Placing the activated carbon powder or activated carbon block in the reducing agent box 153 instead of directly in the first channel 151 can avoid blowing the activated carbon into the air duct 12 when the gas flows, hindering the gas flow or soiling the clothes in the chamber 11. Furthermore, the air inlet 157 and the first air outlet 158a can be covered with a filter to prevent the reducing agent from being blown into the air duct 12 by the gas.

[0072] In other embodiments, the reducing agent may also be chemical substances such as ferrous sulfate, cuprous sulfate, etc.

[0073] Further, after a period of use, the reducing ability of the reducing agent may weaken or even fail. At this time, the detachable setting of the reducing agent box 153 also makes it more convenient for the user to take out the reducing agent box 153 to replace the reducing agent.

[0074] In a variation, a desiccant box (not shown) may be further provided in the first channel 151, and the desiccant box is provided upstream of the reducing agent box 153 along the gas flow direction. Thus, the gas first flows through the desiccant box, and the dried gas further flows through the reducing agent box 153, so that the mixed ozone is reduced to avoid the damp gas from affecting the reduction effect. For example, activated carbon that is in contact with damp gas for a long time will form a water film on the surface, which prevents the internal activated carbon from contacting the gas.

[0075] In some embodiments, reference Figure 5 and Figure 6 , along the flow direction of the gas in the air duct 12, the main body 154 may have a relative front wall 154h and a rear wall 154i, the air inlet 157 is opened in the front wall 154h, and the air outlet 158 is opened in the rear wall 154i. As a result, the flow direction of the gas in the main body 154 is roughly consistent with the flow direction in the entire air duct 12, so that the gas can pass through the main body 154 efficiently and quickly, thereby improving the gas flow efficiency in the circulation loop. Further, after the gas enters the multi-channel module 15, it can flow from one end of the first channel 151 or the second channel 152 to the other end, and the internal space utilization rate of the multi-channel module 15 is high. Furthermore, when the first channel 151 is turned on, the contact time between the gas and the reducing agent box 153 arranged in the first channel 151 can also be increased to fully reduce the residual ozone in the gas.

[0076] Specifically, the front wall 154 h and the rear wall 154 i of the main body 154 are arranged opposite to each other in the y direction, the front wall 154 h is arranged on the side where gas flows into the main body 154 , and the rear wall 154 i is arranged on the side where gas flows out of the main body 154 .

[0077] Further, an air inlet 157 is provided on the front wall 154h so that the gas in the air duct 12 can flow into the first chamber 155 or the second chamber 156 inside the main body 154.

[0078] Further, an air outlet 158 is provided on the rear wall 154i so that the gas inside the main body 154 can flow out.

[0079] In a specific embodiment, as Figure 4 shown, the air outlet 158 includes a first air outlet 158a and a second air outlet 158b. The first air outlet 158a and the second air outlet 158b are arranged at intervals in the x direction on the rear wall 154i of the main body 154 and are respectively communicated with the first channel 151 and the second channel 152.

[0080] Continue to refer to Figure 5 and Figure 6 , in some embodiments, the first chamber 155 and the second chamber 156 can be arranged side by side in a first plane, wherein the first plane is perpendicular to the flow direction of the gas in the air duct 12. Thus, the internal structure of the multi-channel module 15 can be simplified, and the manufacturing process of the multi-channel module 15 can be made simpler.

[0081] In some embodiments, the volumes of the first chamber 155 and the second chamber 156 can be equal. Thus, it is ensured that the sizes of both chambers are sufficient to obtain better gas flow efficiency. Further, other functional components similar in volume to the reductant cartridge 153, such as a deodorant cartridge or a flavor enhancer cartridge, can also be accommodated in the second chamber 156 to fragrance the clothes in the chamber 11. Further, the equal volumes of the first chamber 155 and the second chamber 156 can also make the appearance shape of the multi-channel module 15 more regular, facilitating production and assembly.

[0082] Continue to refer to Figures 4 to 8 , in some embodiments, the main body 154 may include: a box body 154c, a top cover 154a, and a first sealing structure 154d. Thus, the top cover 154a is detachable, facilitating the replacement of the components accommodated inside the main body 154, such as the reductant cartridge 153.

[0083] Further, the box body 154c includes a bottom wall 154j, a front wall 154h, a rear wall 154i, and a pair of side walls 154k. The partition 159 is located between the pair of side walls 154k. The bottom wall 154j, the front wall 154h, the rear wall 154i, one of the pair of side walls 154k, and the partition 159 together enclose the upwardly open first cavity 155. The bottom wall 154j, the front wall 154h, the rear wall 154i, the other of the pair of side walls 154k, and the partition 159 together enclose the upwardly open second cavity 156.

[0084] In some embodiments, the partition 159 extends upward from the bottom wall 154j. Further, the height of the partition 159 in the z direction can be consistent with that of the pair of side walls 154k. Further, a protruding portion (not shown in the figure) extending downward can be provided on the lower surface of the top cover 154a in the z direction. The shape and position of the protruding portion are adapted to the upper side edge of the partition 159 in the z direction. Thus, when the top cover 154a and the box body 154c are assembled, the upper side edge of the partition 159 in the z direction can abut against the protruding portion and squeeze and deform the first sealing structure 154d provided therebetween, so that the separated first cavity 155 and second cavity 156 have better sealing performance and do not leak from each other when gas passes through.

[0085] In a variation, the partition 159 can extend upward from the bottom wall 154j to exceed the planes where the upward openings of the first cavity 155 and the second cavity 156 are located respectively. Further, the height of the partition 159 in the z direction is consistent with the distance from the lower surface of the top cover 154a to the bottom wall 154j in the assembled state. Thus, in the assembled state, the upper side edge of the partition 159 can abut against the lower surface of the top cover 154a through the first sealing structure 154d, so that the separated first cavity 155 and second cavity 156 have better sealing performance and do not leak from each other when gas passes through.

[0086] In a specific embodiment, the switching member 16 can be used to close the first cavity 155 or the second cavity 156.

[0087] In a specific application scenario for realizing the drying function, as Figure 7 shown, when the switching member 16 closes the first cavity 155 to block the first channel 151, the first cavity 155 is jointly enclosed by the top cover 154a, the partition 159, the bottom wall 154j, the rear wall 154i, the side wall 154k that forms the first cavity 155 among the pair of side walls 154k, and the switching member 16.

[0088] In a specific application scenario for realizing the sterilization function, as Figure 8As shown, when the switching member 16 closes the second chamber 156 to block the second passage 152, the second chamber 156 is jointly surrounded by the top cover 154a, the partition 159, the bottom wall 154j, the rear wall 154i, the side walls 154k of the second chamber 156 formed by a pair of side walls 154k, and the switching member 16.

[0089] Further, the opening may include a first opening 155a facing upward of the first chamber 155 and a second opening 156a facing upward of the second chamber 156. Thus, the reducing agent cartridge 153 can be placed into the first chamber 155 through the first opening 155a to reduce ozone in the gas flowing through the first passage 151. The first chamber 155 and the second chamber 156 are open upward, which also facilitates cleaning of the interior of the main body 154.

[0090] Further, the top cover 154a is used to close the opening, for example, closing the first opening 155a and the second opening 156a simultaneously. Thus, when replacing the reducing agent cartridge 153 or the reducing agent in the reducing agent cartridge 153, the opening can be opened only by removing the top cover 154a, and the operation is simple.

[0091] In some embodiments, the top cover 154a and the cartridge body 154c may be connected by a fixing structure, for example, a screw-nut mating structure.

[0092] Further, the main body 154 further includes a first sealing structure 154d located between the cartridge body 154c and the top cover 154a and disposed around the opening in a circle. Thus, the first sealing structure 154d is provided at the connection between the cartridge body 154c and the top cover 154a, which can ensure the airtightness of the main body 154. Further, the first sealing structure 154d can also improve the sealing performance between the first chamber 155 and the second chamber 156, and prevent the gas flowing through one of the first passage 151 and the second passage 152 from leaking and diffusing to the other of the first passage 151 and the second passage 152.

[0093] In a specific embodiment, when the cartridge body 154c and the top cover 154a are assembled, the first sealing structure 154d is deformed by extrusion. Thus, the sealing effect can be significantly improved.

[0094] Further, the first sealing structure 154d may be made of an elastic material, for example, rubber.

[0095] Further, in combination Figure 6 , since the upper side of the partition 159 in the z direction contacts the lower surface of the top cover 154a, the first sealing structure 154d may include a portion adapted to the upper side of the partition 159 to further make the separated first chamber 155 and the second chamber 156 independent of each other. Among them, Figure 6The diagonally filled part exemplarily shows the sealing area formed by the first sealing structure 154d.

[0096] Continuing to refer to Figures 4 to 6 , the cartridge 154c includes: a body 154l which has a forward opening 154g along the flow direction of the gas in the air duct 12; a front cover 154b for closing at least a part of the opening 154g, and the front cover 154b is adapted to form the front wall 154h. Thus, the body 154l and the front cover 154b of the cartridge 154c are also detachable, facilitating the opening or closing of the first chamber 155 and the second chamber 156, and further making the disassembly and replacement of the components disposed in the cartridge 154c more convenient.

[0097] Specifically, in the y direction, the cartridge 154c includes the body 154l and the front cover 154b which are adjacently arranged, and the body 154l and the front cover 154b cooperate to complete the definition of the space inside the cartridge 154c.

[0098] Further, the body 154l has a forward opening 154g along the flow direction of the gas, and the opening 154g is adapted to allow the gas in the air duct 12 to flow into the first chamber 155 or the second chamber 156.

[0099] Further, when the front cover 154b is in complete cooperation with the cartridge 154c, at least a part of the opening 154g is closed, and the unclosed part is adapted to form an air inlet 157. At this time, the front cover 154b forms the front wall 154h of the cartridge 154c. Thus, the air inlet 157 is formed on the front cover 154b and is in communication with the air duct 12 for allowing the gas to flow into the main body portion 154.

[0100] In a variant, a third sealing structure (not shown in the figure) may further be provided between the front cover 154b and the body 154l, and the third sealing structure is arranged in a circle around the opening 154g. When the front cover 154b and the body 154l are assembled, the third sealing structure is extruded to deform, so as to further improve the airtightness of the cartridge 154c.

[0101] In some embodiments, in combination with Figures 5 to 8 , the switching member 16 includes: a plate portion 162 which can move between the multiple positions (for example, the first position and the second position) so that one of the first channel 151 and the second channel 152 is conducted while the other is blocked.

[0102] Further, in a plane perpendicular to the gas flow direction, the area of the plate portion 162 can be adapted to the cross-sectional area of the first chamber 155 or the second chamber 156, so that when the plate portion 162 moves to the front of the first chamber 155 or the second chamber 156 along the gas flow direction, one of the first chamber 155 and the second chamber 156 can be closed, and the other can be opened.

[0103] Further, the switching member 16 further includes a driving portion 161 for driving the plate portion 162 to move. Thus, the driving portion 161 can drive the plate portion 162 to block the first channel 151 or the second channel 152, and at the same time conduct the other channel. In other words, when realizing different functions, the switching member 16 can conveniently and quickly control the access of the first channel 151 or the second channel 152 to the circulation loop by driving the plate portion 162. Further, the plate portion 162 and the driving portion 161 have low manufacturing costs and are easy to implement, which is beneficial to reducing the production and manufacturing costs.

[0104] Further, the driving portion 161 may include: a motor 161a; a rotating shaft 161b connected to the output shaft 161c of the motor 161a, and the plate portion 162 is connected to the rotating shaft 161b and can rotate with the rotating shaft 161b. Thus, the motor 161a can drive the rotating shaft 161b to rotate, and further drive the plate portion 162 to rotate to conduct one of the first channel 151 and the second channel 152, and at the same time block the other. Further, the plate portion 162 and the driving portion 161 have low manufacturing costs and are easy to implement, which is beneficial to reducing the production and manufacturing costs.

[0105] Further, the axial direction of the rotating shaft 161b (for example, the z direction), the gas flow direction in the air duct 12 (for example, the opposite direction of the y direction), and the direction from the first channel 151 to the second channel 152 (for example, the x direction) are perpendicular to each other in pairs. Thus, the plate portion 162 rotates to move to the front of the first channel 151 or the second channel 152 along the gas flow direction to close the first chamber 155 or the second chamber 156 and prevent the air flow from flowing through the first channel 151 or the second channel 152.

[0106] In a specific embodiment, as Figures 4 to 8 a through hole 154e may be formed in the top cover 154a, and the motor 161a is disposed outside the main body portion 154 and is connected to the rotating shaft 161b disposed inside the main body portion 154 through the through hole 154e. Thus, the motor 161a is disposed outside the main body portion 154, which can avoid the corrosion and aging of parts caused by long-term contact with ozone-containing gas and humid and hot gas, and further extend the service life of the motor 161a.

[0107] Furthermore, the multi-channel module 15 further includes a motor cover 154f, and the motor cover 154f covers the motor 161a to fix the latter to the top cover 154a. Thus, the motor cover 154f can protect and position the motor 161a, preventing it from shifting during operation and affecting the switching effect of the switching component 16.

[0108] Furthermore, the motor cover 154f and the top cover 154a can be fixedly connected by a fixing member 165. The fixing member 165 can be, for example, a screw.

[0109] In a specific embodiment, as Figures 5 to 8 shown, the axial direction of the rotating shaft 161b can be perpendicular to the bottom wall 154j of the main body portion 154, and one of a pair of side edges of the plate portion 162 in the x direction is connected to the rotating shaft 161b, and the plate portion 162 is driven by the rotating shaft 161b to rotate to any one of the plurality of positions. Thus, on the plane where the bottom wall 154j is located, the gas flow direction (for example, the opposite direction of the y direction) is perpendicular to the direction from the first channel 151 to the second channel 152 (for example, the x direction). Further, the axial direction of the rotating shaft 161b (for example, the z direction) is also perpendicular to both of them.

[0110] In some embodiments, at least a part of the rotating shaft 161b along the z direction can be a hollow structure to save materials and reduce costs. For example, referring to Figure 7 and Figure 8 , the part of the rotating shaft 161b close to the motor 161a can be a hollow structure.

[0111] In some embodiments, the rotating shaft 161b can be a hollow cylinder, and a fixing portion 164 (as Figure 5 shown) is provided on the bottom wall 154j of the box body, and the fixing portion 164 extends upward along the z direction from the bottom wall 154j. Further, the fixing portion 164 can be inserted into the interior of the rotating shaft 161b to fix the central axis of the rotating shaft 161b and prevent the rotating shaft 161b from shifting during rotation.

[0112] Furthermore, the fixing portion 164 can be, for example, a cylinder, and its diameter is adapted to the inner diameter of the hollow part of the rotating shaft 161b. Specifically, the diameter of the fixing portion 164 can be slightly smaller than the inner diameter of the hollow part of the rotating shaft 161b to ensure that the fixing portion 164 can be inserted into the rotating shaft 161b. At the same time, there is a non-zero gap between the inner wall of the rotating shaft 161b and the fixing portion 164, which can also avoid generating excessive friction during rotation.

[0113] In a variant, the fixing portion 164 may also be an annular protrusion extending upward in the z direction from the bottom wall 154j. The inner diameter of the annular protrusion is adapted to the diameter of the rotating shaft 161b, so that the rotating shaft 161b can be inserted into the recessed area in the middle of the annular protrusion, and it is ensured that the rotating shaft 161b rotates within the circle formed by the annular protrusion. Thus, the central axis of the rotating shaft 161b can also be fixed, avoiding the deviation of the rotating shaft 161b during rotation.

[0114] Furthermore, there is a certain distance between the rotating shaft 161b and the front wall 154h, and the distance is at least slightly greater than the length of the upper and lower sides of the plate portion 162, so as to avoid collision or excessive friction with the front wall 154h when the plate portion 162 rotates.

[0115] In a variant, the axial direction of the rotating shaft 161b may be parallel to the flow direction of the gas in the air duct 12. Thus, when the axial direction of the rotating shaft 161b is parallel to the flow direction of the gas, the plate portion 162 can be arranged at a position close to the air inlet 157. Thereby, the length of the multi-channel module 15 in the gas flow direction can be shortened, and the size of the multi-channel module 15 can be further reduced.

[0116] Specifically, the main body portion 154 may be cylindrical, and the plate portion 162 is circular. Further, the shape of the plate portion 162 is adapted to the cross-section of the main body portion 154, and the central axis of the main body portion 154 may pass through the center of the circle of the plate portion 162. Thus, in a plane perpendicular to the gas flow direction, the plate portion 162 can rotate inside the cylindrical main body portion 154. Further, the circular plate portion 162 may be provided with at least one small hole, and the contour shape and size of the small hole are both adapted to the contour shape and cross-sectional area of the first chamber 165 or the second chamber 166. The small hole can move to any one of a plurality of positions (for example, the first position and the second position) as the plate portion 162 is driven by the rotating shaft 161b, so as to conduct one of the first channel 151 and the second channel 152, and at the same time, the other of the two channels is blocked by the part of the plate portion 162 other than the small hole.

[0117] Furthermore, in the above embodiment, the top cover 154a may not be provided additionally.

[0118] In a variant, the plate portion 162 may also be semi-circular, and the partition 159 divides the space of the cylindrical main body portion 154 into the first chamber 155 and the second chamber 156 on average. Further, the shape of the semi-circular plate portion 162 is adapted to half of the cross-section of the main body portion 154, so that when the plate portion 162 moves to the first position or the second position, the first chamber 155 or the second chamber 156 is surrounded by the side wall 154k, the rear wall 154i, the partition 159 and the plate portion 162 of the cylindrical main body portion 154.

[0119] In a variant, the driving part 161 may include: a motor 161a; a driving rod (not shown in the figure), which is connected to the output shaft 161c of the motor 161a, and the plate part 162 can move back and forth under the push of the driving rod. Thus, the plate part 162 can be driven by the motor 161a and the driving rod to reciprocate in the first plane (a plane perpendicular to the gas flow direction) in the direction from the first channel 151 to the second channel 152 (for example, the x direction) to conduct one of the first channel 151 and the second channel 152 while blocking the other. Further, since the plate part 162 only needs to move in the first plane, it can also avoid wasting the space inside the multi-channel module 15 and improve the space utilization rate.

[0120] For example, the plate part 162 can move left and right along the x direction on the first plane where the first cavity 155 and the second cavity 156 are arranged side by side.

[0121] Further, the side edges of the plate part 162 are respectively in contact with the bottom wall 154j of the box body 154c, one of the pair of side walls 154k, and the top cover 154a to close the first cavity 155 or the second cavity 156.

[0122] Further, the area of the plate part 162 can be slightly larger than the cross-sectional area of the first channel 151 or the second channel 152 to ensure that the first channel 151 or the second channel 152 can be blocked. At the same time, the area of the plate part 162 is smaller than the area of the opening 154g to ensure that when one of the first channel 151 and the second channel 152 is blocked, the other can be conducted.

[0123] Continue to refer to Figures 5 to 8 , the clothing care device 1 may further include: a second sealing structure 163, which is arranged around the edge of the plate part 162. Thus, the second sealing structure 163 can further seal the gap between the plate part 162 and the inner wall of the first cavity 155 or the second cavity 156, improve the sealing effect, and avoid gas leakage.

[0124] In a specific embodiment, the second sealing structure 163 is fixed on the plate part 162 along the outer edge of the plate part 162 and moves with the plate part 162 to improve the sealing effect of the first cavity 155 or the second cavity 156.

[0125] In a variant, the second sealing structure 163 can also be fixed on the inner walls of the first cavity 155 and the second cavity 156. For example, it is arranged along the lower surface in the z direction of the bottom wall 154j, one of the pair of side walls 154k, the top cover 154a, and the partition 159. When the plate part 162 closes the corresponding cavity, the edge of the plate part 162 tightly abuts against the second sealing structure 163 arranged in this cavity.

[0126] In Figure 5 and Figure 6 In the illustrated embodiment, at least one side surface of the reducing agent cartridge 153 may be provided with a vent hole 153a communicating with the interior. Thus, gas can flow into the reducing agent cartridge 153 from the vent hole 153a, and then come into sufficient contact with the reducing agent in the cartridge, so as to ensure that ozone mixed in the gas is fully adsorbed and reduced.

[0127] Specifically, the number of vent holes 153a may be multiple and arranged in an array on the surface where they are located.

[0128] Furthermore, the size of the reducing agent cartridge 153 may be adapted to the volume of the first chamber 155. For example, the dimension of the reducing agent cartridge 153 in the y direction is substantially equal to the dimension of the first chamber 155 in the y direction. Thus, the gas entering the first chamber 155 can fully flow through the reducing agent cartridge 153, preventing the gas from flowing out of the first chamber 155 directly without reduction through the gap.

[0129] In some embodiments, the projected area of the reducing agent cartridge 153 on the plane formed by the y direction and the x direction is slightly smaller than the cross-sectional area of the first chamber 155 on this plane. That is, there is a small gap between the opposite side surfaces of the reducing agent cartridge 153 in the x direction and the inner wall of the adjacent first chamber 155. This gap enables the gas filling the first chamber 155 to gradually enter the reducing agent cartridge 153 for reaction.

[0130] Furthermore, among the side surfaces of the reducing agent cartridge 153, vent holes 153a may be provided on the front and rear side surfaces in the y direction, so that gas can flow into the reducing agent cartridge 153 from the front side surface and flow out from the rear side surface.

[0131] Furthermore, among the side surfaces of the reducing agent cartridge 153, vent holes 153a may also be provided on the upper side surface in the z direction and / or the left and right side surfaces in the x direction, so that the gas can come into more sufficient contact with the reducing agent in the reducing agent cartridge 153.

[0132] Continue to refer to Figure 2 and Figure 3 , in some embodiments, the clothing care device 1 further includes: a blower device 17 disposed in the air duct 12, and the blower device 17 is used to promote the gas flow in the air duct 12. Thus, the blower device 17 can increase the gas flow speed in the air duct 12 and further improve the drying or disinfection efficiency. Furthermore, the blower device 17 can also be used to provide the gas flow speed and flow direction in the air duct 12.

[0133] Further, along the flow direction of the gas in the air duct 12, the blower device 17 is located upstream of the drying module 13. Thus, the blower device 17 can blow the gas towards the drying module 13, and the heated gas enters the chamber 11 to achieve drying.

[0134] Further, the blower device 17 is arranged upstream of the drying module 13 so that the gas is blown from the blower device 17 towards the drying module 13, and the dry and hot gas heated by the drying module 13 further flows into the chamber 11 to dry the clothes.

[0135] In a variant, the blower device 17 can also be arranged downstream of the drying module 13. At this time, since the gas near the blower device 17 is blown away, a pressure difference is generated in the air duct 12 near the blower device 17, and the gas will still flow in the blowing direction of the blower device 17 to complete the circulation.

[0136] In a specific embodiment, the blower device 17 can control the flow direction of the gas. By controlling the blowing direction of the blower device 17 and / or the rotation direction of the fan in the blower device 17 (for example, forward rotation or reverse rotation), the circulation loop can be made to circulate in the Figure 2 and Figure 3 direction shown or its reverse direction.

[0137] In a specific embodiment, the clothing care device 1 further includes: a condensation device 18, arranged on the air duct 12, for exchanging heat with the gas flowing in the air duct 12. Thus, through heat exchange, the temperature of the humid gas in the air duct 12 is reduced to make it saturated cold air. Further, the water vapor in the gas condenses into liquid water and separates from the gas due to the temperature reduction, thereby reducing the humidity of the gas.

[0138] In some embodiments, the condensation device 18 can be, for example, a condenser.

[0139] Further, along the flow direction of the gas in the air duct 12, the condensation device 18 is located between the chamber 11 and the drying module 13.

[0140] Specifically, when performing the drying function, the gas flows through the drying module 13, the chamber 11, and the condensation device 18 in sequence and circulates in this order.

[0141] More specifically, after the gas is heated by the drying module 13, it becomes dry and hot gas, which enters the chamber 11 to dry the clothes to be dried in the chamber 11. The water attached to the wet clothes in the chamber 11 evaporates into water vapor due to the increase in temperature in the chamber 11 and mixes into the gas. The dry and hot gas is transformed into humid and hot gas due to the mixing of water vapor. Further, after the humid and hot gas flows out of the chamber 11, it is condensed by the condensing device 18, so that the water vapor mixed in the gas is liquefied, and the humidity of the mixed gas is reduced to become saturated cold gas, thus completing the drying of the gas. Then it is heated by the drying module 13 again to become dry and hot gas. The dry and hot gas contacts the wet clothes and becomes humid and hot gas, and then enters the condensing device 18. Such a cycle is carried out, and finally the drying of the clothes in the chamber 11 is realized.

[0142] In a variant, the drying module 13 can be, for example, a heat pump module. Since the heat pump module includes two heat exchange devices for heating and condensing, an additional condensing device 18 can be not provided at this time. Thereby, the internal structure of the clothing care device 1 is further simplified.

[0143] Continue to refer to Figures 1 to 3 , the clothing care device 1 further includes: a control module 2 configured to selectively execute a drying program or a sterilization program. When the drying program is executed, the control module 2 controls the drying module 13 to operate, the switching member 16 moves to the second position, and the ozone generating module 14 is in a non-operating state; when the sterilization program is executed, the control module 2 controls the ozone generating module 14 to operate, the switching member 16 moves to the first position, and the drying module 13 is in a non-operating state.

[0144] The control module 2 can be, for example, a single-chip microcomputer of the clothing treatment device 1 for controlling the overall operation of the clothing treatment device 1. Alternatively, the control module 2 can be, for example, a processor dedicated to executing this embodiment.

[0145] In a typical application scenario, in Figure 2 the embodiment shown, when the control module 2 executes the drying program, the gas flow process includes:

[0146] First, the blower device 17 gives the gas a flow direction and makes the gas flow towards the drying module 13 at a certain flow rate.

[0147] Then, after the gas is heated by the drying module 13, it becomes dry and hot gas and further flows towards the multi-channel module 15.

[0148] Inside the multi-channel module 15, the control module 2 controls the operation of the motor, moves the switching component 16 to the second position to block the first channel 151, and conducts the second channel 152 at the same time. After the dry-heat gas passes through the second channel 152, it continues to flow along the air duct 12 to the chamber 11. At this time, the ozone generation module 14 is in a non-operating state.

[0149] Inside the chamber 11, the dry-heat gas can raise the ambient temperature inside the chamber 11, and the temperature of the damp clothes inside the chamber 11 also rises accordingly. Further, as the temperature rises, the liquid water attached to the clothes accelerates evaporation and becomes water vapor mixed into the gas inside the chamber 11. Thus, the dry-heat gas becomes a humid-heat gas due to mixing with a large amount of water vapor, and the humidity rises.

[0150] Further, the humid-heat gas flows out of the chamber 11 and is condensed by the condensing device 18. The water vapor mixed in the gas re-liquefies into liquid water due to the temperature decrease and separates from the gas. Thus, as the water vapor liquefies and the gas temperature decreases, the humid-heat gas becomes a saturated cold gas, and the humidity decreases.

[0151] Finally, the saturated cold gas flows back to the blower device 17 and continues the next cycle.

[0152] In a typical application scenario, referring to Figure 3 , when the control module 2 executes the disinfection program, the gas flow process includes:

[0153] First, the blower device 17 gives the gas a flow direction and makes the gas flow towards the multi-channel module 15 at a certain flow rate. At this time, the drying module 13 and the condensing device 18 are in a non-operating state.

[0154] Then, inside the multi-channel module 15, the control module 2 controls the operation of the motor, moves the switching component 16 to the first position to conduct the first channel 151, and blocks the second channel 152 at the same time. After the gas passes through the first channel 151, it flows through the ozone generation module 14.

[0155] The ozone released by the ozone generation module 14 is mixed into the gas and enters the chamber 11 along the air duct 12.

[0156] Inside the chamber 11, the gas mixed with ozone fully contacts the clothes to disinfect the clothes. After the disinfection is completed, the mixed gas continues to flow through the air duct 12 to the blower device 17 and is blown by the blower device 17 towards the multi-channel module 15.

[0157] Further, the mixed gas continues to flow into the first channel 151 and flows through the reducing agent box 153 provided in the first channel 151. After sufficient contact with the reducing agent, the ozone in the mixed gas is adsorbed and reduced to stabilize the ozone concentration inside the chamber 11 and avoid ozone leakage and pollution of the user's home environment.

[0158] Further, in a specific implementation scenario, when the sterilization program runs to the end (or after it ends), the ozone generation module 14 can stop running first. At this time, the switching component 16 remains in the first position to continue conducting the first channel 151. The blower device 17 can continue to run for a period of time so that the gas in the air duct 12 continues to circulate in the circulation loop, ensuring that the residual ozone in the gas can be completely absorbed by the reductant cartridge 153.

[0159] In a variant, when executing the sterilization program, the drying module 13 can be in an operating state to heat the gas in the air duct 12. In a higher temperature environment, the sterilization process of ozone and the process of ozone reduction can be accelerated, improving the operating efficiency. Further, the operating temperature of the drying module 13 in the sterilization program can be lower than that in the drying program, thereby avoiding energy waste.

[0160] Continue to refer to Figure 2 and Figure 3 As shown, the chamber 11 can include a first chamber 111 and a second chamber 112, and the first chamber 111 and the second chamber 112 are respectively connected to the same air duct 12 in a parallel manner.

[0161] Specifically, the chamber 11 can include an independent first chamber 111 and a second chamber 112. The first chamber 111 and the second chamber 112 can be, for example, the chambers 11 defined by the first drum and the second drum respectively. When the gas in the air duct 12 flows into the chamber 11, it is split into two streams and enters the first chamber 111 and the second chamber 112 respectively. Thus, the first chamber 111 and the second chamber 112 can be simultaneously connected to the circulation loop, and the clothes in the first chamber 111 and the second chamber 112 can be dried or sterilized simultaneously, improving the overall working efficiency of the device and enabling the clothing care device 1 to achieve a double-drum drying or double-drum sterilization mode.
