[0028] The inventive concepts of the present disclosure will be described below using terms commonly used by those skilled in the art to convey the essence of their work to other persons skilled in the art. However, these inventive concepts can be embodied in many different forms and should not be considered limited to the embodiments described herein.

[0029] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The directional terms (such as: up, down) in this application are all conventional directional terms for the clothing care machine when it is normally placed and operating normally. Figure 1 The coordinates in .

[0030] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0031] In order to solve the problem that the drying components of the clothing care machine in the prior art are relatively complicated and how to simultaneously eliminate the moisture in the window, this embodiment proposes an air duct system and a clothing care machine for clothing care, as shown in the attached Figure 1-4 As shown, the air duct system includes:

[0032] An air duct assembly, the air duct assembly comprising a drying air duct 5, an external exhaust air duct 6, and an air inlet duct, one end of the air inlet duct being in communication with the inner cavity of the clothing care machine, and the other end being able to be in communication with the drying air duct 5 and the external exhaust air duct 6 respectively, the drying air duct 5 being able to be in communication with the inner cavity of the clothing care machine, and the external exhaust air duct 6 being able to be in communication with the external environment of the clothing care machine;

[0033] A heating device 35, which is arranged in the drying air duct 5 and is used to heat the air flow;

[0034] A fan 32, wherein the fan 32 is disposed in the air duct assembly and is used to provide flow power for the airflow;

[0035] The reversing component is connected to the air duct component and is used to switch the flow direction of the airflow according to the functional requirements of the clothing care machine; specifically, through the switching of the reversing component, the air inlet channel can be connected to one of the drying air duct 5 and the external exhaust air duct 6.

[0036] Although the inner cavity of the clothing care machine is not shown in the figure, it is the same as the clothing care machines in the prior art, that is, a space for placing clothes, and clothing care can be performed in this space.

[0037] In the present application, the air flow of the clothing care machine is internally circulated by connecting the air inlet channel with the drying duct 5, so that the air flow in the inner cavity of the clothing care machine flows into the drying duct 5 through the air inlet channel, flows through the heating device 35 to form a drying air flow, and then the drying air flow flows back to the inner cavity of the clothing care machine, so that the clothes can be dried quickly and conveniently.

[0038] By connecting the air inlet channel with the external exhaust duct 6, the air flow of the clothing care machine is discharged externally (or called external circulation), so that the high-temperature and high-humidity gas (such as steam) in the inner cavity of the clothing care machine flows into the external exhaust duct 6 through the air inlet channel, and is discharged to the external environment of the clothing care machine through the external exhaust duct 6. This process can quickly discharge water vapor after the clothing care stage is completed, greatly reducing the condensed water vapor generated at the window, reducing the influence of water vapor on the permeability of the window, and allowing the user to directly see the clothing care effect through the window.

[0039] Therefore, the present application sets up an air duct system with a simple and compact structure and a high degree of integration in components and functions. Only by using a set of air duct components and a fan 32, the purposes of drying clothes and eliminating water vapor from the window can be achieved. On the one hand, there is no need to set up a separate drying system, which is beneficial to optimizing the space utilization inside the clothing care machine, simplifying the composition of the drying components, and ensuring the drying efficiency. On the other hand, the water vapor can be quickly discharged into the external environment of the clothing care machine, which greatly reduces the condensed water vapor generated at the window and reduces the influence of water vapor on the transparency of the window, so that the user can directly see the clothing care effect through the window, thereby improving the user experience.

[0040] The air duct assembly includes an air inlet duct 4, one end of which is connected to the space outside the inner cavity of the clothing care machine, and the other end can be respectively connected to the drying duct 5 and the external exhaust duct 6. Therefore, by further setting the air inlet duct 4, on the one hand, during the internal circulation of the air flow, the air inlet area is increased to a certain extent, the air flow used for drying is increased, which is conducive to improving the drying efficiency. On the other hand, during the external circulation of the air flow, since the air flow entering from the air inlet duct 4 is at a low temperature, the low-temperature air flow enters the external exhaust duct 6 and mixes with the high-temperature water vapor in the external exhaust duct 6, so that the high-temperature water vapor is cooled and condensed, which can reduce the temperature and humidity of the air flow discharged from the external exhaust duct 6, and reduce the impact on the external environment or human body.

[0041] At least a part of the duct structure of the air inlet duct 4 and at least a part of the duct structure of the external exhaust duct 6 are arranged adjacent to each other in a manner that allows for airflow inter-wall heat exchange. Thus, the low-temperature airflow of the air inlet duct 4 exchanges heat with the high-temperature water vapor in the external exhaust duct 6, and then enters the external exhaust duct 6 for direct mixing, so that the high-temperature water vapor in the external exhaust duct 6 can successively undergo a two-stage cooling and condensation process, which can further effectively reduce the temperature and humidity of the airflow discharged from the external exhaust duct 6, and reduce the impact on the external environment or human body.

[0042] Among them, the partition heat exchange form between the air inlet duct 4 and the outer exhaust duct 6 can be any form such as downstream partition heat exchange, countercurrent partition heat exchange, and cross-flow partition heat exchange. In this application, it is preferred that the air inlet duct 4 and the outer exhaust duct 6 are countercurrent partition heat exchange, that is, the main flow directions of the airflows are opposite during the partition heat exchange process to improve the heat exchange efficiency. In order to avoid ambiguity, this application only limits the air duct section between the air inlet duct 4 and the outer exhaust duct 6 that can exchange heat between the partitions. For the air duct section without partition heat exchange, the main flow direction of the airflow can be determined based on the layout of each air duct, and this application does not impose any restrictions.

[0043] The air duct assembly includes an upper cover 1, a middle piece 2, and a lower cover 3 connected in sequence from top to bottom, a drying air duct 5 and an external exhaust air duct 6 are formed between the middle piece 2 and the lower cover 3, and the lower cover 3 is provided with a second air inlet 36, one side of the second air inlet 36 can be connected to the inner cavity of the clothing care machine, and the other side can be connected to the drying air duct 5 and the external exhaust air duct 6 respectively, and an air inlet duct 4 is formed between the upper cover 1 and the middle piece 2. Among them, the second air inlet 36 can be regarded as an air inlet channel, so that the gas in the inner cavity of the clothing care machine can flow into the air duct assembly.

[0044] Specifically, an assembly cavity 31 is formed between the middle piece 2 and the lower cover 3, and the fan 32 is arranged in the assembly cavity 31. The second air inlet 36 is directly connected to the air inlet side 321 of the fan 32, and the air inlet duct 4 is directly connected to the air inlet side 321 of the fan 32, so that one fan 32 can simultaneously inhale air from the inner cavity of the clothing care machine and the external space of the inner cavity of the clothing care machine, which is beneficial to simplify the arrangement of components; the air outlet side 322 of the fan 32 is respectively connected to the inlet of the drying air duct 5 and the inlet of the external exhaust air duct 6, and a reversing component is provided on the air outlet side 322 of the fan 32, which is used to connect or cut off any one of the drying air duct 5 and the external exhaust air duct 6. Thus, while the fan 32 simultaneously draws in air from the second air inlet 36 and the air inlet duct 4, the reversing component connects or disconnects the drying duct 5 and the external exhaust duct 6 according to the functional requirements of the clothing care machine, so that the fan 32 can deliver air to the drying duct 5 and / or the external exhaust duct 6 as needed.

[0045] The upper cover 1 has a first air inlet 11, which is connected to the air inlet duct 4 as the air inlet side of the air inlet duct 4. Correspondingly, the air outlet side of the air inlet duct 4 can also be provided with a hole structure (not specifically shown in the figure) and directly connected to the air inlet side 321 of the fan 32. The drying duct 5 and the external exhaust duct 6 can be regarded as two branch air paths of the air outlet side 322 of the fan 32. The middle piece 2 is provided with an exhaust port 21, which is connected to the external exhaust duct 6 as the air outlet side of the external exhaust duct 6. Of course, the exhaust port 21 can be directly connected to the external environment of the clothing care machine by an external exhaust pipe.

[0046] For the air outlet of the drying duct 5, the duct assembly includes an air outlet 51, the air outlet 51 is connected to the lower cover 3 or the middle piece 2, one end of the air outlet 51 is connected to the drying duct 5, and the other end is provided with an air outlet 52 directly connected to the inner cavity of the clothing care machine. Preferably, the air outlet 52 is located above the clothing. As shown in the drawings of the present application, the air outlet 52 can be directly located above the hanger assembly 9, so that the air flow for drying can flow directly to the clothing, thereby improving the drying efficiency. In addition, the air outlet 51 is connected to the lower cover 3 or the middle piece 2 in a detachable manner, so that the air outlet 51 with different drying air outlet conditions can be replaced according to different clothing. Of course, if component replacement is not considered, the air outlet 51 can also be integrally formed with the lower cover 3 or the middle piece 2, such as integral injection molding, etc. For the heating device 35 of the present application, an existing heating element, such as a heating wire, etc., can be directly used, and no further description is given.

[0047] For the on-off of the drying air duct 5 and the external exhaust air duct 6, the reversing component can be a reversing valve, which realizes connection or disconnection through linear motion or rotational motion, so that when the drying air duct 5 is connected, the external exhaust air duct 6 is disconnected, and vice versa. In addition, the reversing component can also include two independent valves, which correspond to the drying air duct 5 and the external exhaust air duct 6 one by one, and can adjust the on-off of the drying air duct 5 and the external exhaust air duct 6 separately. That is, in this application, the drying air duct 5 and the external exhaust air duct 6 can be kept in a connected state or in a disconnected state at the same time, which is conducive to fully meeting the control needs of the clothing care machine in different operation processes.

[0048] In the present application, the reversing assembly preferably includes a damper 34 and a damper motor 8, wherein the damper 34 is disposed on the air outlet side 322 of the fan 32, and the damper motor 8 is connected to the damper 34 so that the damper 34 can move to switch the flow direction of the airflow. The damper 34 can be directly driven to rotate by the damper motor 8 to adjust the switching situation.

[0049] Of course, the reversing assembly may also be additionally provided with a transmission member 33, and the damper motor 8 is connected to the damper 34 through the transmission member 33. Under the drive of the damper motor 8, the damper 34 is driven by the transmission member 33 to make a linear motion to adjust the switching situation. Correspondingly, the transmission member 33 may be a gear rack, a belt transmission member, a connecting rod structure, etc.

[0050] The air duct system includes a base 7 connected to the air duct assembly, and the base 7 is arranged on the lower side of the lower cover 3. By setting the base 7, other components of the air duct system can be shielded and decorated in the inner cavity of the clothing care machine, which is beneficial to improving the aesthetics of the inner cavity of the clothing care machine, and can also provide certain protection for the air duct system components above the base 7 to avoid damage to the air duct structure caused by scratches and collisions caused by foreign objects.

[0051] In order to prevent the base 7 from causing spatial interference between individual components of the air duct assembly or blocking the corresponding air flow inlet and outlet, the base 7 is provided with an air inlet interface 71, which is directly connected to the second air inlet 36, so that the air flow in the inner cavity of the clothing care machine can enter the second air inlet 36 from the air inlet interface 71. In addition, the base 7 is also provided with an avoidance port, and the air outlet member 51 can pass through the avoidance port and directly extend into the inner cavity of the clothing care machine.

[0052] Considering that the water vapor in the inner cavity of the clothing care machine can be more evenly sucked into the air duct assembly, the air duct system includes an air inlet 72, the air inlet 72 has a hollow chamber (not shown), the hollow chamber can be connected to the second air inlet 36, and the air inlet 72 is provided with a plurality of air suction ports 73 on one side facing the inner cavity of the clothing care machine, and the water vapor in the inner cavity of the clothing care machine can be evenly sucked into the hollow chamber through the plurality of air suction ports 73, and then enter the air duct assembly through the second air inlet 36. At this time, the air inlet 72 and the second air inlet 36 can be regarded as an air inlet channel, so that the gas in the inner cavity of the clothing care machine can flow into the air duct assembly.

[0053] The arrangement, shape, and size of the air intake 73, such as the air intake 73 arranged in a specific array or in a disorderly arrangement, and the shape is square, round, oval, or irregular, and the opening size is the same or different, or gradually decreases, or gradually increases. This application is not limited thereto, and can be as shown in the attached Figure 4 At the same time, the connection of the air inlet member 72 can be connected to the lower side wall of the lower cover 3 or to the base 7. The air inlet member 72 can be a separate setting or can be integrally formed with the corresponding components. As long as the corresponding connection relationship of the air inlet member 72 is met, this application does not impose too many restrictions.

[0054] At the same time, the present application proposes a control method for a clothing care machine, including a drying process and an exhaust process;

[0055] Specifically, the drying process includes:

[0056] A1, the fan 32 is running, the reversing component cuts off the external exhaust air duct 6, and opens the drying air duct 5;

[0057] A2, the heating device 35 is started;

[0058] A3. The gas in the inner cavity of the clothing care machine flows into the drying duct 5 from the air inlet channel, and the air flow outside the inner cavity of the clothing care machine flows into the drying duct 5 from the air inlet duct 4;

[0059] A4. In the drying air duct 5, the air flow is heated by the heating device 35 to form a hot air flow;

[0060] A5. The hot air flows from the outlet side of the drying air duct 5 into the inner cavity of the clothing care machine to dry the clothes.

[0063] B2. The high-temperature and high-humidity gas in the inner cavity of the clothing care machine flows from the air inlet channel into the external exhaust duct 6;

[0064] B3. The low-temperature airflow outside the inner cavity of the clothing care machine passes through the air inlet duct 4 and performs a wall-type heat exchange with the high-temperature and high-humidity gas in the external exhaust duct 6, so that the high-temperature and high-humidity gas undergoes a first-stage cooling and condensation; the low-temperature airflow after heat exchange flows from the air inlet duct 4 into the external exhaust duct 6, and directly mixes with the high-temperature and high-humidity gas in the external exhaust duct 6 to form a mixed airflow, and the high-temperature and high-humidity gas undergoes a second-stage cooling and condensation;

[0065] B4. The mixed airflow is discharged from the outlet side of the external exhaust duct 6 to the external environment of the clothing care machine.
