[0004] Therefore, how to prevent the drum washing machine from producing odor has become a technical problem to be solved. CONTENT OF THE INVENTION

[0005] The present application provides a fresh air system of a drum washing machine and the drum washing machine, which can quickly dry the door seal, the outer drum and the inner drum, and improve the cleaning ability of the drum washing machine on clothes and the use experience of the user.

[0006] In a first aspect, the present application provides a fresh air system of a drum washing machine, which is applied to the drum washing machine, and the fresh air system comprises:

[0007] A fan has an air outlet;

[0008] A blowing piece has an air inlet, a first blowing port and a second blowing port, the air inlet is communicated with the air outlet, and the first blowing port and the second blowing port are both communicated with the air inlet;

[0009] The first blowing port is located at the first end of the blowing piece, and the first blowing port is configured to be located at one side of the inner wall of the door seal in the drum washing machine;

[0010] The second end of the blowing piece is configured to be installed on the circumferential outer wall of the outer drum in the drum washing machine, the circumferential outer wall of the outer drum has a through hole; the side of the second end of the blowing piece facing the circumferential outer wall of the outer drum has the second blowing port, and the second blowing port is communicated with the through hole.

[0011] The present application has the fan and the blowing piece in the fresh air system, the blowing piece has the air inlet, the first blowing port and the second blowing port, and the first blowing port and the second blowing port are both communicated with the air inlet of the fan through the air inlet. Since the first blowing port is located at one side of the inner wall of the door seal in the drum washing machine, when water is left on the door seal, the fan can accurately blow air to the inner wall of the door seal through the first blowing port, so as to quickly dry the door seal and improve the drying efficiency of the door seal.

[0012] Since the second air supply port is in communication with the inner wall of the outer cylinder, when moisture remains in the inner cylinder, the fan can also accurately supply air from the outer wall of the outer cylinder to the inner cylinder through the second air supply port. Since the outer cylinder is in communication with the inner cylinder, the air flowing to the outer cylinder can also flow into the inner cylinder, so that the fan can accurately supply air to the outer cylinder and the inner cylinder through the second air supply port, thereby quickly drying the outer cylinder and the inner cylinder and improving the drying effect and efficiency of the outer cylinder and the inner cylinder.

[0013] After the door seal, the outer cylinder and the inner cylinder are dried by the fresh air system, bacteria and mold are not easy to breed to produce odor, which can effectively solve the technical problem that the door seal and the inner cylinder of the existing drum washing machine are affected by a large amount of residual moisture, thereby affecting the cleaning ability of the drum washing machine for clothes and the user experience.

[0014] Therefore, by providing the fresh air system, the door seal, the outer cylinder and the inner cylinder can be quickly dried, and the cleaning ability of the drum washing machine for clothes and the user experience can be improved.

[0015] In some embodiments, the fresh air system further comprises an air supply switching piece, the air supply switching piece is movably arranged in the air supply piece, and the air supply switching piece is configured to communicate the air inlet with the first air supply port or the second air supply port when moving in the air supply piece.

[0016] By providing the air supply switching piece, the air supply switching piece can selectively communicate the air inlet with the first air supply port or the second air supply port, so that the fresh air system can accurately and automatically dry the parts required to be dried by the drum washing machine, improve the drying efficiency and effect, and reduce the power of the fan.

[0017] In some embodiments, the air supply switching piece is rotatably arranged in the air supply piece, and the air supply switching piece is configured to communicate the air inlet with the first air supply port or the second air supply port when rotating in the air supply piece. By such arrangement, the air supply switching piece can be movably arranged in the air supply piece, and the air supply switching piece can selectively communicate the air inlet with the first air supply port or the second air supply port.

[0018] In some embodiments, the air supply piece comprises a first air supply section, a second air supply section and a mounting section, the mounting section communicates the first air supply section and the second air supply section, and the side of the mounting section facing the air outlet has the air inlet;

[0019] The end of the first air supply section away from the mounting section forms the first end of the air supply piece, and the end of the second air supply section away from the mounting section forms the second end of the air supply piece;

[0020] The mounting end of the air supply switching piece is rotatably arranged in the mounting section;

[0021] The rotating end of the air supply switching piece is configured to communicate the air inlet with the second air supply outlet when rotating to the side of the mounting section adjacent to the first air supply section;

[0022] The rotating end is further configured to communicate the air inlet with the first air supply outlet when rotating to the side of the mounting section adjacent to the second air supply section.

[0023] In this way, the air supply switching piece can be rotated in the mounting section by the mounting end, so that the rotating end can be rotated around the mounting end in the mounting section when the mounting end rotates in the mounting section, so that the rotating end can rotate to the side of the mounting section adjacent to the first air supply section or the second air supply section, so as to selectively communicate the air inlet with the first air supply outlet or the second air supply outlet.

[0024] In some embodiments, the side of the mounting section facing the air outlet has a first arc-shaped wall, the first arc-shaped wall has the air inlet, and the rotating end abuts against the first arc-shaped wall when the rotating end rotates to the side of the mounting section adjacent to the first air supply section and / or the second air supply section.

[0025] In this way, on the basis of selectively communicating the air inlet with the first air supply outlet or the second air supply outlet, the rotating end can be limited to continue rotating in the mounting section by the first arc-shaped wall, so as to avoid excessive rotation of the rotating end in the mounting section, thereby achieving precise control of the rotating position of the rotating end.

[0026] In some embodiments, the side of the mounting section away from the air outlet has a second arc-shaped wall, the second arc-shaped wall defines a mounting space, and the mounting end is rotatably arranged in the mounting space. In this way, the mounting end and the air supply switching piece can be rotatably arranged in the air supply piece, and the mounting end can rotate in the mounting space to drive the rotating end to rotate in the mounting section to communicate the air inlet with the first air supply outlet or the second air supply outlet.

[0027] In some embodiments, the fresh air system further comprises a driving piece connected with the air supply switching piece, and the driving piece is configured to drive the air supply switching piece to move in the air supply piece, so that the air supply switching piece can selectively communicate the air inlet with the first air supply outlet or the second air supply outlet, and the operation of the fresh air system is simple and friendly to users.

[0028] In some embodiments, the fresh air system further comprises a control piece electrically connected with the driving piece, and the control piece is configured to control the opening and closing and the moving direction of the driving piece.

[0029] In this way, the control member can start the driving member according to the drying requirement of the drum washing machine, and control the moving direction of the driving member, so that the driving member drives the air supply switching member to move towards the side of the mounting section adjacent to the first air supply section, to communicate the air inlet with the second air supply port, or drives the air supply switching member to move towards the side of the mounting section adjacent to the second air supply section, to communicate the air inlet with the first air supply port. In this way, the fresh air system can automatically select the first air supply port or the second air supply port to supply air, and accurately supply air to the part (such as the door seal, the inner drum or the outer drum) of the drum washing machine that needs to be dried, so as to realize the drying function of the door seal, the inner drum or the outer drum.

[0030] In some embodiments, the control member is electrically connected with the fan, and the control member is further configured to control the start and stop of the fan. In this way, when the drum washing machine has a drying requirement or a ventilation requirement, the control member can also automatically start the fan, and when the drum washing machine does not need to be dried or ventilated, the control member can also automatically stop the fan.

[0031] In some embodiments, the first end of the air supply member is configured to pass through the door seal in the radial direction of the door seal, so that the first air supply port is located on the side of the inner wall of the door seal. In this way, on the basis of realizing the fixation of the first end of the air supply member in the cabinet, the fan can accurately supply air to the inner wall of the door seal through the first air supply port, so as to quickly dry the inner wall of the door seal. At the same time, since the first end of the air supply member passes through the door seal in the radial direction of the door seal, the contact between the door body and the door seal in closing the laundry throwing opening will not be affected, so that the door seal will still be pressed between the door body and the cabinet to prevent water, detergent and the like from leaking to the outside of the drum washing machine during the operation of the drum washing machine.

[0032] In some embodiments, the outer drum includes a first drum body and a second drum body connected in communication, and the first drum body is located between the second drum body and the door seal.

[0033] The second end of the air supply member is mounted on the circumferential outer wall of the second drum body, and the circumferential outer wall of the second drum body has a through hole at the position corresponding to the second air supply port, so that the second end of the air supply member can be fixed in the cabinet by means of the second drum body, and the second air supply port can also be communicated with the inside of the second drum body. Since the second drum body is connected in communication with the first drum body, when the second air supply port is communicated with the inside of the second drum body, the second air supply port is also communicated with the inside of the first drum body through the second drum body, so that the communication between the second air supply port and the inside of the outer drum can be realized.

[0034] Compared with the case that the second end of the air supply member is mounted on the first cylinder, when the second end of the air supply member is mounted on the second cylinder, the air flowing out of the second air supply port can enter the second cylinder from the circumferential outer wall of the second cylinder. After the air entering the second cylinder through the second air supply port is dried by the second cylinder, part of the air can enter the rear section of the inner cylinder to dry the rear section of the inner cylinder, and then flow along the inner cylinder towards the front section of the inner cylinder after being dried to dry the front section of the inner cylinder. The remaining air entering the second cylinder through the second air supply port can directly enter the first cylinder and the front section of the inner cylinder to dry the first cylinder and the front section of the inner cylinder. In this way, the air flowing out of the second air supply port can ensure rapid and effective drying of each section of the first cylinder, the second cylinder and the inner cylinder, so that each section of the first cylinder, the second cylinder and the inner cylinder has a better drying effect.

[0035] In some embodiments, the second air supply port is a strip-shaped hole on the air supply member, and the strip-shaped hole extends towards the end of the second cylinder away from the first cylinder;

[0036] The circumferential outer wall of the second cylinder has a plurality of through holes at positions corresponding to the strip-shaped hole.

[0037] Compared with the other holes described above, when the second air supply port is a strip-shaped hole, a larger air supply area can be obtained under the condition that the size of the second end of the air supply member remains unchanged, and the strip-shaped hole has the characteristics of being easy to process.

[0038] Under the condition that the air supply area of the second air supply port is the same, compared with the case that the strip-shaped hole extends along the circumference of the second cylinder, when the strip-shaped hole extends towards the end of the second cylinder away from the first cylinder, the air flowing out of the second air supply port can pass through the through holes on the second cylinder as much as possible and be supplied to the side of the rear section of the inner cylinder away from the front section, so as to realize rapid and effective drying of each section of the first cylinder, the second cylinder and the inner cylinder.

[0039] In some embodiments, the circumferential inner wall of the inner cylinder in the roller washing machine has a clothes lifting rib, and the clothes lifting rib has a through hole;

[0040] The second air supply port is configured to supply air to the inner cylinder through the through hole and the through hole when the through hole rotates to the through hole.

[0041] In this way, the clothes lifting rib has a guiding effect on the air passing through the through hole. Compared with the case that the air entering the inner cylinder disperses on the circumferential inner wall of the inner cylinder, when the air supplied by the second air supply port enters the inner cylinder through the through hole and the through hole, the flow direction of the air can be more concentrated.

[0042] After the clothes are washed by the drum washing machine, the clothes are usually entangled together. In this way, the air sent out by the second air outlet flows out through the through hole, and due to the more concentrated flow direction of the air, the air is more likely to flow into the entangled clothes, and the inner drum and the clothes are ventilated, which better prevents the clothes from producing odor due to air stagnation, and further improves the user experience.

[0043] In some embodiments, the air supply member is disposed near the top surface of the drum washing machine in the circumferential direction of the outer drum.

[0044] Compared with the air supply member being disposed near the bottom surface of the drum washing machine in the circumferential direction of the outer drum, when the air supply member is disposed near the top surface of the drum washing machine in the circumferential direction of the outer drum, the air sent out by the first air outlet and the second air outlet can be uniformly distributed in the inner wall of the door seal, the inner drum, and the outer drum, to better dry the door seal, the outer drum, and the inner drum. In addition, the space between the circumferential direction of the outer drum and the top surface of the cabinet can be reasonably utilized to install the fresh air member in the cabinet.

[0045] In some embodiments, the air supply member is configured to be disposed near one of the side walls of the drum washing machine in the circumferential direction of the outer drum.

[0046] In this way, when the air supply member is disposed near the top surface of the drum washing machine in the circumferential direction of the outer drum, it is also biased towards one of the side walls of the drum washing machine, so as to reasonably utilize the space between the circumferential direction of the outer drum and the top surface and one of the side walls of the cabinet to install the fresh air member in the cabinet, and make the structure of the drum washing machine more compact.

[0047] In some embodiments, the fan is configured to be installed on the circumferential outer wall of the outer drum, so that the air outlet and the air inlet are opposite and communicate with each other. In this way, the fan can be installed in the cabinet by means of the outer drum.

[0048] In a second aspect, the embodiments of the present application provide a drum washing machine, comprising:

[0049] a cabinet having a clothes feeding opening;

[0050] a drum assembly comprising an inner drum and an outer drum, the outer drum being arranged in the cabinet, and the inner drum being rotatably arranged in the outer drum, and the drum openings of the inner drum and the outer drum both facing the clothes feeding opening;

[0051] a door body rotatably arranged on the cabinet to open or close the clothes feeding opening;

[0052] a door seal arranged between the drum opening of the outer drum and the clothes feeding opening;

[0053] The fresh air system of the drum washing machine according to any one of the above, the fresh air system is arranged in the cabinet, the first air outlet of the fresh air system is located on one side of the inner wall of the door seal, and the second air outlet communicates with the inside of the outer drum.

[0054] The drum washing machine provided by the embodiment of the present application can send air to the inner wall of the door seal through the first air outlet by the fan, so as to quickly dry the door seal. The fan can also send air to the outer drum through the second air outlet, and since the outer drum is communicated with the inner drum, the air flowing to the outer drum can also flow into the inner drum, so that the fan can send air to the outer drum and the inner drum through the second air outlet, thereby quickly drying the outer drum and the inner drum.

[0077] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will be combined with the accompanying drawings for the embodiments of the present application to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0078] The embodiments of the present application provide a drum washing machine. Figure 1 A structure schematic view of a drum washing machine 100 at a front face 11 of a cabinet 1 is shown, Figure 2 A schematic view of an inside of the drum washing machine 100 when the door body 4 is opened is shown.

[0079] The structure of the drum washing machine 100 will be further described below in combination with the accompanying drawings and embodiments. For the convenience of description, the width direction of the drum washing machine 100 is defined as the X direction, the depth direction of the drum washing machine 100 is defined as the Y direction, and the height direction of the drum washing machine 100 is defined as the Z direction.

[0080] Referring to Figure 1 and Figure 2 , the drum washing machine 100 comprises a cabinet 1. The cabinet 1 has a laundry loading port 111. In the depth direction (Y direction) of the drum washing machine 100, the cabinet 1 has a front face 11 and a back face 12 oppositely arranged. The front face 11 of the cabinet 1 forms the front face of the drum washing machine 100, and the back face 12 of the cabinet 1 forms the back face of the drum washing machine 100. In the width direction (X direction) of the drum washing machine 100, the cabinet 1 has two side faces 13 oppositely arranged, which form two side walls of the drum washing machine 100. In the height direction (Z direction) of the drum washing machine 100, the cabinet 1 has a top face 14 and a bottom face 15 oppositely arranged. Similarly, the top face 14 of the cabinet 1 forms the top face of the drum washing machine 100, and the bottom face 15 of the cabinet 1 forms the bottom face of the drum washing machine 100. The laundry loading port 111 is arranged on the front face 11 of the cabinet 1.

[0081] Referring to Figure 1 and Figure 2 , the drum washing machine 100 further comprises a drum assembly, which comprises an outer drum 2 and an inner drum 3. The outer drum 2 is arranged in the cabinet 1, and the inner drum 3 is rotatably arranged in the outer drum 2. Moreover, the drum openings of the inner drum 3 and the outer drum 2 both face the laundry loading port 111. In this way, when people use the drum washing machine 100 to wash laundry, the laundry can be loaded into the inner drum 3 through the laundry loading port 111, so that the laundry can be washed when water enters the inner drum 3 and the inner drum 3 rotates relative to the outer drum 2.

[0082] The drum washing machine 100 further comprises a drain pump. The drain pump is arranged in the cabinet 1, and part of the drain pipe is located outside the cabinet 1. The drain pump is in communication with the drain pipe and the outer drum 2. The inner drum 3 is further provided with a communication hole 221 in the circumferential direction, which can realize the communication between the inner drum 3 and the outer drum 2, so that after the drum washing machine 100 finishes washing the laundry, the water in the inner drum 3 can enter the outer drum 2 through the communication hole 221, and then be drained to the outside of the drum washing machine 100 through the drain pump and the drain pipe.

[0083] It should be understood that the drum washing machine 100 further comprises a motor, which is located in the cabinet 1 and connected with the inner drum 3 to drive the inner drum 3 to rotate relative to the outer drum 2 in the outer drum 2. The arrangement position of the motor in the cabinet 1 and the connection between the motor and the inner drum 3 can be determined according to the structure of the existing drum washing machine 100, which will not be described in detail in the embodiments of the present application.

[0084] Referring toFigure 1 and Figure 2 The drum washing machine 100 also includes a door 4. The door 4 is rotatably mounted on the cabinet 1 to open or close the clothes inlet 111. Specifically, after people put clothes into the inner drum 3 through the clothes inlet 111, they can rotate the door 4 to close the clothes inlet 111. After the clothes inlet 111 is closed, the motor can drive the inner drum 3 to rotate relative to the outer drum 2 inside the outer drum 2 in order to wash the clothes.

[0085] like Figure 2 As shown, the drum washing machine 100 also includes a door seal 5. The door seal 5 is located between the opening of the outer drum 2 and the clothes inlet 111. For example, the door seal 5 can be a resilient sealing ring. Specifically, along the depth direction (Y direction) of the drum washing machine 100, one end of the door seal 5 can be looped around the clothes inlet 111 and connected to the casing 1, and the other end of the door seal 5 can be looped around the opening of the outer drum 2 and connected to the outer drum 2, so as to realize the placement of the door seal 5 between the opening of the outer drum 2 and the clothes inlet 111. When the door 4 closes the clothes inlet 111, the door seal 5 contacts the door 4, and the door seal 5 is pressed between the door 4 and the casing, forming a sealed barrier to prevent water, detergent, etc. from leaking to the outside of the drum washing machine 100 during operation.

[0086] It should be noted that the connection method between the door seal 5, the cabinet 1, and the outer drum 2 can be determined according to the structure of the existing drum washing machine 100, and will not be described again in this embodiment.

[0087] After washing clothes, a large amount of water usually remains on the inner wall 51 of the inner drum 3 and door seal 5 of the drum washing machine 100, making them relatively damp. If the inner drum 3 and door seal 5 are not dried in time, bacteria and mold can easily grow in these areas, producing odors. Such odors will affect the cleaning ability of the drum washing machine 100 and the user experience.

[0088] Therefore, how to prevent odors from being generated inside a drum washing machine has become an urgent technical problem to be solved.

[0089] Therefore, the embodiment of the present application provides a fresh air system (hereinafter referred to as the fresh air system) of a drum washing machine 100. The fresh air system can be applied to the drum washing machine 100. The fresh air system has a fan 6 and an air supply part 7. The air supply part 7 has a first air supply port and a second air supply port 722. Both the first air supply port and the second air supply port 722 are in communication with an air outlet 61 of the fan 6. When the door seal 5 and the inner drum 3 have residual moisture, the fan 6 can supply air to the inner wall 51 of the door seal 5 through the first air supply port, so as to quickly dry the door seal 5. The fan 6 can also supply air to the inner drum 3 through the second air supply port 722, so as to quickly dry the inner drum 3. After the door seal 5 and the inner drum 3 are dried, bacteria and mold are not easy to breed and produce odor, which can avoid affecting the cleaning ability of the drum washing machine 100 on clothes and the use experience of the user.

[0090] Specifically, the fresh air system is arranged in the cabinet 1. The first air supply port of the fresh air system is located at one side of the inner wall 51 of the door seal 5, and the second air supply port 722 is in communication with the inside of the outer drum 2. In this way, the fan 6 can supply air to the inner wall 51 of the door seal 5 through the first air supply port, so as to quickly dry the door seal 5. The fan 6 can also supply air to the outer drum 2 through the second air supply port 722. Since the outer drum 2 is in communication with the inner drum 3, the air flowing to the outer drum 2 can also flow into the inner drum 3, so as to realize that the fan 6 supplies air to the outer drum 2 and the inner drum 3 through the second air supply port 722, and quickly dries the outer drum 2 and the inner drum 3.

[0091] It should be understood that the inner wall 51 of the door seal 5 refers to one side of the door seal 5 facing the center of the clothes throwing opening 111. Correspondingly, the outer wall of the door seal 5 refers to one side of the door seal 5 away from the center of the clothes throwing opening 111.

[0092] The related structure of the fresh air system and the drum washing machine 100 will be further described below in combination with the drawings and embodiments.

[0093] Figure 3 、 Figure 5 and Figure 6 respectively show structural schematic diagrams of a fresh air system and a drum assembly in different viewing angles, Figure 4 show a partial exploded view of a drum assembly and a fresh air system, Figure 7 show a structural schematic diagram of the inside of a fresh air system and a drum assembly, so as to view the internal structure of the air supply part 7.

[0094] Referring to Figures 3 to 7The fresh air system comprises a fan 6 and a air supply part 7. The fan 6 has an air outlet 61. The air supply part 7 has an air inlet 7311, a first air outlet and a second air outlet 722. The air inlet 7311 is in communication with the air outlet 61, and the first air outlet and the second air outlet 722 are both in communication with the air inlet 7311, so that the first air outlet and the second air outlet 722 are in communication with the air outlet 61 through the air inlet 7311.

[0095] The first air outlet is located at the first end 711 of the air supply part 7 and is configured to be located on the side of the inner wall 51 of the door seal 5 in the drum washing machine 100. The second end 721 of the air supply part 7 is configured to be mounted on the circumferential outer wall of the outer drum 2, and the circumferential outer wall of the outer drum 2 has a through hole 221. The second end 721 of the air supply part 7 faces the side of the circumferential outer wall of the outer drum 2 and has the second air outlet 722, which is in communication with the through hole 221 to realize the communication of the second air outlet 722 with the inside of the outer drum 2 on the circumferential outer wall of the outer drum 2.

[0096] Since the first air outlet is configured to be located on the side of the inner wall 51 of the door seal 5 in the drum washing machine 100, when the door seal 5 has residual moisture, the fan 6 can accurately supply air to the inner wall 51 of the door seal 5 through the first air outlet, thereby quickly drying the door seal 5 and improving the drying efficiency of the door seal 5.

[0097] After the air supplied through the first air outlet dries the inner wall 51 of the door seal 5, it will enter the outer drum 2 through the drum opening of the outer drum 2 to dry the outer drum 2, and also enter the inner drum 3 through the drum opening of the inner drum 3 to dry the inner drum 3. In addition, since the outer drum 2 is in communication with the inner drum 3, the air dried in the outer drum 2 will also enter the inner drum 3 to dry the inner drum 3.

[0098] Since the air supplied through the first air outlet dries the inner wall 51 of the door seal 5 and carries away the moisture on the door seal 5, the drying effect of the air supplied through the first air outlet on the outer drum 2 and the inner drum 3 is not very good.

[0099] Therefore, the second air outlet 722 is provided in the embodiment of the present application. Since the second air outlet 722 is in communication with the inside of the outer drum 2, when the inner drum 3 has residual moisture, the fan 6 can also accurately supply air from the circumferential outer wall of the outer drum 2 to the inside of the outer drum 2 through the second air outlet 722. Since the outer drum 2 is in communication with the inner drum 3, the air flowing to the outer drum 2 can also flow into the inner drum 3, so that the fan 6 can accurately supply air to the outer drum 2 and the inner drum 3 through the second air outlet 722, thereby quickly drying the outer drum 2 and the inner drum 3 and improving the drying effect and drying efficiency of the outer drum 2 and the inner drum 3.

[0100] The door seal 5, the outer drum 2 and the inner drum 3 are dried by the fresh air system, and bacteria and mold are not easy to breed to produce odor, which can effectively solve the technical problem that the door seal 5 and the inner drum 3 of the existing drum washing machine 100 are affected by a large amount of residual moisture, and the cleaning ability of the drum washing machine 100 on clothes and the user experience are affected.

[0101] Therefore, by setting the fresh air system, the embodiments of the present application can realize the rapid drying of the door seal 5, the outer drum 2 and the inner drum 3, and improve the cleaning ability of the drum washing machine 100 on clothes and the user experience.

[0102] People often forget to take clothes in the drum washing machine 100 after washing clothes. At this time, since the door body 4 of the drum washing machine 100 closes the clothes dropping port 111 on the cabinet 1, the clothes will be trapped in the drum washing machine 100, and the air in the drum washing machine 100 will not circulate with the outside, which will cause the air to be trapped. If these clothes are not taken out for a long time in the drum washing machine 100, the clothes will produce odor due to the trapped air in the drum washing machine 100. This will also affect the user experience.

[0103] When the fresh air system is applied to the drum washing machine 100, since the fan 6 can send air to the inner drum 3 through the second air outlet 722, the fresh air system of the embodiments of the present application can also ventilate the inner drum 3, thereby preventing the clothes from producing odor due to being trapped in the inner drum 3, and further improving the user experience.

[0104] It should be noted that the air flowing out of the first air outlet and the second air outlet 722 can be discharged to the outside of the drum washing machine 100 after drying the door seal 5, the outer drum 2 and the inner drum 3, or re-enter the fan 6 and the air supply member 7 after drying to continue drying the door seal 5, the outer drum 2 and the inner drum 3.

[0105] Referring to Figures 3 to 5 and Figure 7 , the outer drum 2 usually has a water inlet 222 which is in communication with the outside of the drum washing machine 100. As an example, the air flowing out of the first air outlet and the second air outlet 722 can be discharged to the outside of the drum washing machine 100 through the water inlet 222 after drying the door seal 5, the outer drum 2 and the inner drum 3.

[0106] Referring to Figures 3 to 5 and Figure 7 , in some embodiments, the first end 711 of the air supply member 7 can be configured to pass through the door seal 5 in the radial direction of the door seal 5, so that the first air outlet is located on the side of the inner wall 51 of the door seal 5. By setting in this way, on the basis of realizing the fixation of the first end 711 of the air supply member 7 in the cabinet 1, the fan 6 can accurately send air to the inner wall 51 of the door seal 5 through the first air outlet, so as to quickly dry the inner wall 51 of the door seal 5.

[0107] At the same time, since the first end 711 of the air supply member 7 is arranged in the door seal 5 along the radial direction of the door seal 5, the door body 4 will not affect the contact between the laundry dropping port 111 and the door seal 5, so that the door seal 5 will still be compressed between the door body 4 and the cabinet, so as to prevent water, detergent and the like from leaking to the outside of the drum washing machine 100 during the operation of the drum washing machine 100.

[0108] Referring to Figure 7 In order to arrange the first end 711 of the air supply member 7 in the door seal 5 along the radial direction of the door seal 5, a through hole should be arranged on the outer wall of the door seal 5, which penetrates the outer wall and the inner wall 51 of the door seal 5. When the first end 711 of the air supply member 7 is arranged in the door seal 5, it can be interference-fitted with the first end 711 of the air supply member 7, so as to better fix the first end 711 of the air supply member 7 in the door seal 5 and enhance the stability of the installation of the first end 711 of the air supply member 7 in the door seal 5.

[0109] Referring to Figure 7 In some embodiments, the outer tub 2 includes a first tub body 21 and a second tub body 22 connected in communication. That is, the outer tub 2 includes two first and second tub bodies 21 and 22 which are independent of each other. In the axial direction of the first tub body 21, the first and second tub bodies 21 and 22 are detachably connected by means of flanges, fasteners or welding.

[0110] Alternatively, in other embodiments, the outer tub 2 can be a one-piece structural member, that is, the outer tub 2 does not include the first and second tub bodies 21 and 22. The first tub body 21 can be regarded as the front half of the outer tub 2 in this embodiment, and the second tub body 22 can be regarded as the rear half of the outer tub 2 in this embodiment.

[0111] Compared with the case where the outer tub 2 is a one-piece structural member, when the outer tub 2 includes the first and second tub bodies 21 and 22, the first and second tub bodies 21 and 22 can be machined separately and then connected to form the outer tub 2, which can simplify the manufacturing difficulty of the outer tub 2 and make the outer tub 2 easy to process.

[0112] Hereinafter, the structure of the outer tub 2 and the fresh air system will be further described by taking the outer tub 2 including the first and second tub bodies 21 and 22 as an example.

[0113] Referring to Figure 7The first cylinder 21 is located between the second cylinder 22 and the door seal 5. The second end 721 of the air supply member 7 can be mounted on the circumferential outer wall of the second cylinder 22, and the circumferential outer wall of the second cylinder 22 has a through hole 221 at a position corresponding to the second air supply port 722, so that the second end 721 of the air supply member 7 can be fixed in the cabinet 1 while the second air supply port 722 is in communication with the inside of the second cylinder 22.

[0114] Since the second cylinder 22 is in communication with the first cylinder 21, when the second air supply port 722 is in communication with the inside of the second cylinder 22, the second air supply port 722 is also in communication with the inside of the first cylinder 21 through the second cylinder 22, so that the second air supply port 722 is in communication with the inside of the outer cylinder 2.

[0115] The second end 721 of the air supply member 7 can be connected to the circumferential outer wall of the second cylinder 22 by clamping, fasteners, or the like, so that the second end 721 of the air supply member 7 is mounted on the circumferential outer wall of the second cylinder 22. For example, the fasteners can be screws, bolts, or the like.

[0116] In some embodiments, the second end 721 of the air supply member 7 can also be mounted on the circumferential outer wall of the first cylinder 21. The second end 721 of the air supply member 7 can also be connected to the circumferential outer wall of the first cylinder 21 by clamping, fasteners, or the like, so that the second end 721 of the air supply member 7 is mounted on the circumferential outer wall of the first cylinder 21.

[0117] The circumferential outer wall of the first cylinder 21 has a through hole 221 at a position corresponding to the second air supply port 722, so that the second end 721 of the air supply member 7 can be fixed in the cabinet 1 while the second air supply port 722 is in communication with the inside of the second cylinder 22 through the first cylinder 21.

[0118] For ease of description, the end of the inner cylinder 3 opposite to the first cylinder 21 is defined as the front section, and the end of the inner cylinder 3 opposite to the second cylinder 22 is defined as the rear section.

[0119] Since the first cylinder 21 is adjacent to the door seal 5, when the air flowing out of the second air supply port 722 enters the circumferential outer wall of the first cylinder 21, part of the air flowing into the part of the inner cylinder 3 opposite to the first cylinder 21 can directly flow towards one side of the door seal 5, affecting the drying effect of the second cylinder 22 and the inner cylinder 3 at the rear section.

[0120] When the second end 721 of the air supply member 7 is installed on the second cylinder 22, the air flowing out of the second air supply port 722 can enter the second cylinder 22 from the circumferential outer wall of the second cylinder 22. After the air entering the second cylinder 22 from the second air supply port 722 dries the second cylinder 22, part of the air can enter the rear section of the inner cylinder 3 to dry the rear section of the inner cylinder 3, and then flow along the inner cylinder 3 towards the front section of the inner cylinder 3 to dry the front section of the inner cylinder 3. The remaining air entering the second cylinder 22 from the second air supply port 722 can directly enter the first cylinder 21 and the front section of the inner cylinder 3 to dry the first cylinder 21 and the front section of the inner cylinder 3. In this way, the air flowing out of the second air supply port 722 can quickly and effectively dry each section of the first cylinder 21, the second cylinder 22, and the inner cylinder 3, so that each section of the first cylinder 21, the second cylinder 22, and the inner cylinder 3 has a good drying effect.

[0121] Hereinafter, the structure of the fresh air system will be further described with the second end 721 of the air supply member 7 installed on the second cylinder 22 as an example.

[0122] In some embodiments, the second air supply port 722 is a strip-shaped hole, a circular hole, an elliptical hole, a hexagonal hole, or a special-shaped hole on the air supply member 7. The special-shaped hole refers to a non-standard-shaped hole, for example, the special-shaped hole includes a heart-shaped hole, etc. Compared with the other holes described above, when the second air supply port 722 is a strip-shaped hole, a larger air supply area can be obtained under the condition that the size of the second end 721 of the air supply member 7 remains unchanged, and the strip-shaped hole has the characteristics of being easy to process.

[0123] Hereinafter, the structure of the fresh air system will be further described with the strip-shaped hole as an example.

[0124] Referring to Figure 7 In some embodiments, the strip-shaped hole can extend towards one end of the second cylinder 22 away from the first cylinder 21 to increase the air supply area of the second air supply port 722.

[0125] Alternatively, in some embodiments, the strip-shaped hole can also extend along the circumference of the second cylinder 22, which can also increase the air supply area of the second air supply port 722. The circumferential outer wall of the second cylinder 22 has a plurality of through holes 221 at positions corresponding to the strip-shaped hole.

[0126] Under the condition that the air supply area of the second air supply port 722 remains unchanged, compared with the strip-shaped hole extending along the circumference of the second cylinder 22, when the strip-shaped hole extends towards one end of the second cylinder 22 away from the first cylinder 21, the air flowing out of the second air supply port 722 can pass through the through holes 221 on the second cylinder 22 as much as possible, and be supplied to the side of the rear section of the inner cylinder 3 away from the front section, so as to achieve quick and effective drying of each section of the first cylinder 21, the second cylinder 22, and the inner cylinder 3.

[0127] Referring to Figure 7 , the plurality of through holes 221 are arranged in an array on the circumferential outer wall of the second cylinder 22 at positions corresponding to the strip-shaped holes. For example, the array arrangement of the plurality of through holes 221 can include a rectangular array, a circular array, a honeycomb array, etc. The honeycomb array refers to an arrangement of the plurality of through holes 221 forming a hexagonal grid and a structure similar to a honeycomb.

[0128] Alternatively, in some embodiments, the plurality of through holes 221 can also be arranged in a random manner on the circumferential outer wall of the second cylinder 22 at positions corresponding to the strip-shaped holes.

[0129] Compared to the plurality of through holes 221 arranged in a random manner on the second cylinder 22, when the plurality of through holes 221 are arranged in an array on the second cylinder 22, the through holes 221 can be uniformly distributed on the circumferential outer wall of the second cylinder 22, so that the air flowing out of the second air outlet 722 can be as uniformly as possible to the second cylinder 22, so as to further improve the drying speed and drying effect of each section of the first cylinder 21, the second cylinder 22 and the inner cylinder 3. At the same time, when the plurality of through holes 221 are arranged in an array on the second cylinder 22, the manufacturing process of the second cylinder 22 can be simplified, the production effect of the second cylinder 22 can be improved, and the manufacturing cost can be reduced, which is more suitable for large-scale production of the second cylinder 22.

[0130] As shown in Figure 7 , in some embodiments, the length L1 of the strip-shaped hole can be greater than one-half of the length L2 of the second cylinder 22, so that the second air outlet 722 has a larger air supply area, which can increase the air supply amount of the second air outlet 722, and further improve the drying speed and drying effect of the air flowing out of the second air outlet 722 on each section of the first cylinder 21, the second cylinder 22 and the inner cylinder 3.

[0131] Figure 8 shows Figure 7 a cross-sectional view in the A-A direction. Referring to Figure 8 , the drum washing machine 100 has a plurality of laundry lifting ribs 31 on the circumferential inner wall 51 of the inner cylinder 3. The laundry lifting rib 31 can be understood as a raised rib on the circumferential inner wall 51 of the inner cylinder 3. The laundry lifting rib 31 is used to lift the laundry when the drum washing machine 100 is running, so that the laundry can be thrown from a high place to a low place of the inner cylinder 3 when the inner cylinder 3 rotates, and the laundry is cleaned by the principle of throwing.

[0132] The number of laundry lifting ribs 31 is a plurality. The plurality of laundry lifting ribs 31 can be uniformly distributed along the circumference of the inner cylinder 3. Figure 8 Three laundry lifting ribs 31 are shown in the , which do not constitute a limitation on the number of laundry lifting ribs 31. For example, the number of laundry lifting ribs 31 can also be two, four, etc.

[0133] Figure 9 For Figure 8 Enlarged view at B.

[0134] Referring to Figure 9 In some embodiments, the clothes lifting ribs 31 can have through holes 311. The second air outlet 722 is configured to send air to the inner drum 3 through the through holes 221 and the through holes 311 when the through holes 311 are rotated to the through holes 221. In this way, the clothes lifting ribs 31 have a guiding effect on the air passing through the through holes 221. Compared with the air flowing in all directions on the circumferential inner wall 51 of the inner drum 3 after entering the inner drum 3, the air sent by the second air outlet 722 can flow more concentratedly when passing through the through holes 221 and the through holes 311.

[0135] After the drum washing machine 100 finishes washing the clothes, the clothes are usually tangled together. In this way, after the air sent by the second air outlet 722 flows out through the through holes, the air flows more concentratedly, so that the air is more likely to flow into the tangled clothes, and the inner drum 3 and the clothes are ventilated, which can better prevent the clothes from producing odors due to air stagnation, and further improve the user experience.

[0136] Referring to Figure 8 In some embodiments, the air supply member 7 can be arranged near the top surface of the drum washing machine 100 in the circumferential direction of the outer drum 2. Compared with arranging the air supply member 7 near the bottom surface of the drum washing machine 100 in the circumferential direction of the outer drum 2, arranging the air supply member 7 near the top surface of the drum washing machine 100 in the circumferential direction of the outer drum 2 can help the air sent by the first air outlet and the second air outlet 722 to be evenly distributed in the inner wall 51 of the door seal 5, the outer drum 2, and the inner drum 3, so as to better dry the door seal 5, the outer drum 2, and the inner drum 3. In addition, the space between the circumferential direction of the outer drum 2 and the top surface 14 of the cabinet 1 can be reasonably utilized to install the fresh air member in the cabinet 1.

[0137] Referring to Figure 8 In some embodiments, when the air supply member 7 is arranged near the top surface of the drum washing machine 100 in the circumferential direction of the outer drum 2, the air supply member 7 is configured to be arranged near one of the side walls of the drum washing machine 100 in the circumferential direction of the outer drum 2. In this way, when the air supply member 7 is arranged near the top surface of the drum washing machine 100 in the circumferential direction of the outer drum 2, the air supply member 7 is also biased towards one of the side walls of the drum washing machine 100, so as to reasonably utilize the space between the circumferential direction of the outer drum 2 and the top surface 14 and one of the side surfaces 13 of the cabinet 1 to install the fresh air member in the cabinet 1, and make the structure of the drum washing machine 100 more compact.

[0138] Referring to Figure 7 and Figure 8In some embodiments, the fan 6 is configured to be mounted on the circumferential outer wall of the outer drum 2, so that the air outlet 61 is opposite to and communicates with the air inlet 7311. In this way, the fan 6 can be arranged in the cabinet 1 by means of the outer drum 2.

[0139] For example, referring to Figure 7 and Figure 8 When the air inlet 7311 of the air supply part 7 is opposite to the first drum body 21, the fan 6 can be mounted on the circumferential outer wall of the first drum body 21. When the air inlet 7311 of the air supply part 7 is opposite to the second drum body 22, the fan 6 can be mounted on the circumferential outer wall of the second drum body 22.

[0140] The fan 6 can be connected to the circumferential outer wall of the first drum body 21 or the second drum body 22 by clamping, fasteners or the like, so that the fan 6 is mounted on the circumferential outer wall of the first drum body 21 or the second drum body 22.

[0141] Figure 10 An enlarged view at C is shown. Figure 7 An enlarged view at C is shown.

[0142] For example, referring to Figure 10 In some embodiments, the fresh air system can further include an air supply switching part 8. For example, the air supply switching part 8 can include but is not limited to a plate-shaped structure. The air supply switching part 8 is movably arranged in the air supply part 7, and the air supply switching part 8 is configured to communicate the air inlet 7311 with the first air outlet or the second air outlet 722 when moving in the air supply part 7. Through the arrangement of the air supply switching part 8, the air supply switching part 8 can selectively communicate the air inlet 7311 with the first air outlet or the second air outlet 722, so that the fresh air system can accurately and automatically dry the parts of the drum washing machine 100 that need to be dried, improve the drying efficiency and drying effect, and at the same time, reduce the power of the fan 6.

[0143] For example, when the drum washing machine 100 needs to dry the door seal 5, the air supply switching part 8 can communicate the air inlet 7311 with the first air outlet, so that the fan 6 sends the air at the air outlet 61 to the side where the inner wall 51 of the door seal 5 is located through the first air outlet, to quickly dry the door seal 5 and avoid the side where the inner wall 51 of the door seal 5 is located from producing odor due to dampness.

[0144] For another example, when the drum washing machine 100 needs to dry the inner drum 3 and the outer drum 2, the air supply switching part 8 can communicate the air inlet 7311 with the second air outlet 722, so that the fan 6 sends the air at the air outlet 61 to the inside of the outer drum 2 and the inner drum 3 through the second air outlet 722, to quickly dry the drum and the inner drum 3 and avoid the drum and the inner drum 3 from producing odor due to dampness.

[0145] It should be noted that in other embodiments, the fresh air system can also not be provided with the air supply switching piece 8, that is, the air inlet 7311 is always communicated with the first air supply port and the second air supply port 722. In this way, when the fan 6 is started, the first air supply port and the second air supply port 722 supply air at the same time, which can dry the door seal 5, the outer barrel 2 and the inner barrel 3, and achieve air exchange of the inner barrel 3, but the power requirement of the fan 6 is very high.

[0146] Hereinafter, the structure of the fresh air system will be further described with the fresh air system having the air supply switching piece 8 as an example.

[0147] Referring to Figure 10 , the air supply switching piece 8 is rotationally arranged in the air supply piece 7, and the air supply switching piece 8 is configured to be able to communicate the air inlet 7311 with the first air supply port or the second air supply port 722 when rotating in the air supply piece 7. In this way, the air supply switching piece 8 can be arranged to move in the air supply piece 7, and the air supply switching piece 8 can selectively communicate the air inlet 7311 with the first air supply port or the second air supply port 722.

[0148] It should be noted that Figure 10 in the air supply switching piece 8 is rotationally arranged in the air supply piece 7 is only an example of the air supply switching piece 8 arranged to move in the air supply piece 7, and does not constitute a limitation on the arrangement of the air supply switching piece 8. For example, the air supply switching piece 8 can also be movably arranged in the air supply piece 7, and the air supply switching piece 8 can also communicate the air inlet 7311 with the first air supply port or the second air supply port 722 when moving in the air supply piece 7 along the length direction of the air supply piece 7. In this application, the specific arrangement of the air supply switching piece 8 in the air supply piece 7 is not further limited.

[0149] Hereinafter, the structure of the fresh air system will be further described with the air supply switching piece 8 rotationally arranged in the air supply piece 7 as an example.

[0150] Referring to Figure 10 , the air supply piece 7 includes a first air supply section 71, a second air supply section 72 and a mounting section 73. The mounting section 73 communicates the first air supply section 71 and the second air supply section 72, and the side of the mounting section 73 facing the air outlet 61 has the air inlet 7311. Specifically, the mounting section 73 can be arranged between the first air supply section 71 and the second air supply section 72, so that the mounting section 73 communicates the first air supply section 71 and the second air supply section 72.

[0151] The end of the first air supply section 71 away from the mounting section 73 forms a first end 711 of the air supply piece 7, and the end of the second air supply section 72 away from the mounting section 73 forms a second end 721 of the air supply piece 7. That is, the first air supply port is arranged on the end of the first air supply section 71 away from the mounting section 73, and the second air supply port 722 is arranged on the end of the second air supply section 72 away from the mounting section 73.

[0152] The mounting end 81 of the air supply switching piece 8 is rotationally arranged in the mounting section 73. The rotating end 82 of the air supply switching piece 8 is configured to communicate the air inlet 7311 with the second air supply port 722 when the rotating end 82 is rotated to the side of the mounting section 73 adjacent to the first air supply section 71. The rotating end 82 is also configured to communicate the air inlet 7311 with the first air supply port when the rotating end 82 is rotated to the side of the mounting section 73 adjacent to the second air supply section 72. In this way, the air supply switching piece 8 is rotationally arranged in the mounting section 73 through the mounting end 81, so that when the mounting end 81 rotates in the mounting section 73, the rotating end 82 is driven to rotate in the mounting section 73 around the mounting end 81, and the rotating end 82 can be rotated to the side of the mounting section 73 adjacent to the first air supply section 71 or the second air supply section 72, so as to selectively communicate the air inlet 7311 with the first air supply port or the second air supply port 722.

[0153] Referring to Figure 10 , the side of the mounting section 73 facing the air outlet 61 has a first arc-shaped wall 731, and the first arc-shaped wall 731 has the air inlet 7311, so that the air inlet 7311 is close to the air outlet 61, and the air inlet 7311 is in communication with the air outlet 61.

[0154] In addition, when the rotating end 82 is rotated to the side of the mounting section 73 adjacent to the first air supply section 71 and / or the second air supply section 72, the rotating end 82 abuts against the first arc-shaped wall 731. In this way, on the basis of realizing the selective communication of the air inlet 7311 with the first air supply port or the second air supply port 722 by the air supply switching piece 8, the first arc-shaped wall 731 can limit the continuous rotation of the rotating end 82 in the mounting section 73, so as to avoid the over-rotation of the rotating end 82 in the mounting section 73, thereby realizing the accurate control of the rotating position of the rotating end 82.

[0155] It should be noted that the term "and / or" used in the present application is only used to describe the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which means that A exists alone, B exists alone, and A and B exist at the same time. In addition, the character " / " in this paper generally represents that the front and rear associated objects have an "or" relationship. For example, the "first air supply section 71 and / or the second air supply section 72" mentioned above refers to the existence of the first air supply section 71 alone, the existence of the second air supply section 72 alone, and the existence of the first air supply section 71 and the second air supply section 72 at the same time.

[0156] Referring to Figure 10 In some embodiments, the side of the mounting section 73 away from the air outlet 61 can also have a second arc-shaped wall 732, and the second arc-shaped wall 732 defines a mounting space 7321. Specifically, by controlling the bending arc of the second arc-shaped wall 732, a mounting space 7321 can be defined on the inner side of the second arc-shaped wall 732.

[0157] The mounting end 81 is rotatably arranged in the mounting space 7321, so as to realize the rotation mounting of the mounting end 81 and the air supply switching piece 8 in the air supply piece 7. Meanwhile, the mounting end 81 can rotate in the mounting space 7321, so as to drive the rotation end 82 to rotate in the mounting segment 73 when the mounting end 81 rotates in the mounting space 7321, so as to communicate the air inlet 7311 with the first air supply port or the second air supply port 722.

[0158] It should be understood that the size of the mounting space 7321 is related to the rotation angle of the mounting end 81, and the rotation angle of the mounting end 81 is related to the position of the rotation end 82 abutting against the first arc-shaped wall 731. In the embodiment of the present application, the size of the mounting space 7321 and the rotation angle of the mounting end 81 are not limited further.

[0159] Preferably, the size of the mounting space 7321 can meet the requirement of the rotation angle of the mounting end 81, and the air supply switching piece 8 does not abut against the second arc-shaped wall 732 before the rotation end 82 abuts against the first arc-shaped wall 731. Because, if the air supply switching piece 8 abuts against the second arc-shaped wall 732 before the rotation end 82 abuts against the first arc-shaped wall 731, the rotation end 82 cannot abut against the first arc-shaped wall 731 due to the rotation of the rotation end 82 not being in place, which affects the communication effect of the air inlet 7311 with the first air supply port or the second air supply port 722, and the air flowing out of the air inlet 7311 cannot be concentrated to flow towards the first air supply port or the second air supply port 722, which affects the drying efficiency of the door seal 5, the inner drum 3 and the outer drum 2.

[0160] The fresh air system further comprises a driving piece 9 (not shown), the driving piece 9 is connected with the air supply switching piece 8, and the driving piece 9 is configured to drive the air supply switching piece 8 to move in the air supply piece 7, so that the air supply switching piece 8 can selectively communicate the air inlet 7311 with the first air supply port or the second air supply port 722. The operation of the fresh air system is simple and friendly to users.

[0161] For example, when the air supply switching piece 8 is rotatably arranged in the mounting segment 73, the driving piece 9 can be a rotating motor, and when the air supply switching piece 8 is movably arranged in the mounting segment 73, the driving piece 9 can be a telescopic motor.

[0162] The fresh air system can further include a control member. The control member is electrically connected with the driving member 9, and is configured to control the opening and closing of the driving member 9 and the moving direction of the driving member 9. In this way, the control member can start the driving member 9 according to the drying requirement of the drum washing machine 100, and control the moving direction of the driving member 9, so that the driving member 9 drives the air supply switching member 8 to move towards the side of the mounting section 73 adjacent to the first air supply section 71, to connect the air inlet 7311 with the second air supply opening 722, or to drive the air supply switching member 8 to move towards the side of the mounting section 73 adjacent to the second air supply section 72, to connect the air inlet 7311 with the first air supply opening. In this way, the fresh air system can automatically select air supply from the first air supply opening or the second air supply opening 722, and accurately supply air to the part (such as the door seal 5, the inner drum 3 or the outer drum 2) of the drum washing machine 100 that needs to be dried, to realize the drying function of the door seal 5, the inner drum 3 or the outer drum 2.

[0163] In addition, when the drum washing machine 100 has a ventilation requirement for the inner drum 3, the control member can also open the driving member 9, so that the driving member 9 drives the air supply switching member 8 to move towards the side of the mounting section 73 adjacent to the first air supply section 71, to connect the air inlet 7311 with the second air supply opening 722, to accurately supply air to the inner drum 3 through the outer drum 2, to realize the ventilation function of the inner drum 3.

[0164] When the drum washing machine 100 does not have a drying requirement or a ventilation requirement, the control member can also automatically close the driving member 9.

[0165] It should be understood that the opening and closing mentioned in the embodiments of the present application can include starting or closing, and starting can be understood as opening. For example, starting the driving member 9 can be understood as opening the driving member 9. In the following, similar descriptions can be understood in this way.

[0166] The control member is also electrically connected with the fan 6, and the control member is further configured to control the opening and closing of the fan 6. In this way, when the drum washing machine 100 has a drying requirement or a ventilation requirement, the control member can also automatically start the fan 6, and when the drum washing machine 100 does not have a drying requirement or a ventilation requirement, the control member can also automatically close the fan 6.

[0167] It should be noted that the control member can adopt an existing module capable of controlling the opening and closing of the driving member 9 and the fan 6. In the embodiments of the present application, the structure of the control member will not be described further.

[0168] The control member can be connected with the control system in the drum washing machine 100, so that when the control system detects that the drum washing machine 100 has a drying requirement or a ventilation requirement, the control member can control the opening and closing of the driving member 9 and the fan 6.

[0169] The control system further comprises a detection module and a processing module, and the processing module is connected with the detection module and the control element. The detection module can monitor the residual water amount of the door seal 5 and the inner drum 3 in real time, or monitor the position where odor is accumulated in the drum washing machine 100 in real time, and transmit the detection result to the processing module. The processing module can determine whether the drum washing machine 100 has a drying requirement or a ventilation requirement according to the detection result of the detection module. When the processing module determines that the drum washing machine 100 has a drying requirement or a ventilation requirement, the opening and closing of the fan 6 and the driving element 9 and the activity direction of the driving element 9 are controlled by the control element, so as to automatically dry the part of the drum washing machine 100 that needs to be dried, or automatically ventilate the inner drum 3, thereby eliminating the odor in the drum washing machine 100, improving the user experience and the cleaning ability of the drum washing machine 100 on clothes.
