DETAILED DESCRIPTION

[0068] ​The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art based on the embodiments of the utility model belong to the scope of protection of the utility model.

[0069] The laundry treatment drum is prone to bacteria and mold breeding due to long-term closed and humid state, which will affect the washing effect of the laundry and cause harm to the human body.

[0070] Therefore, the utility model embodiment provides a kind of laundry treatment equipment, by being arranged between box and laundry treatment drum new air structure, the air inlet of new air component of new air structure is connected on the detergent box in box and box, and the inner cavity of box is communicated, the air outlet of new air component is communicated with the inner cavity of laundry treatment drum by ventilation pipe, to make the air in box can be into the inner cavity of laundry treatment drum by air inlet, air outlet and ventilation pipe, to carry out air drying to the inner cavity of laundry treatment drum, in turn, it can avoid the problem that bacteria and mold are prone to breeding in laundry treatment drum to a certain extent, while improve the stability of new air structure.

[0071] The laundry treatment equipment provided by the utility model will be described in detail below with reference to the drawings and specific embodiments:

[0072] Referring to Figures 1 to 13 The utility model provides a kind of laundry treatment equipment, including box 1, laundry treatment drum 2, detergent box 3 and new air structure 4.

[0073] Laundry treatment drum 2, detergent box 3 and new air structure 4 are all located in box 1, and new air structure 4 and detergent box 3 are all located on the outer side of laundry treatment drum 2.

[0074] New air structure 4 includes ventilation pipe 41 and new air component 42.New air component 42 is connected with box 1 and detergent box 3 respectively, and new air component 42 has air inlet 421 and air outlet 422 in communication, air inlet 421 is communicated with the inner cavity of box 1, and the two ends of ventilation pipe 41 are communicated with air outlet 422 and the inner cavity of laundry treatment drum 2, so that the air in box 1 can enter the inner cavity of laundry treatment drum 2 through air inlet 421, air outlet 422 and ventilation pipe 41.

[0075] Specifically, box 1 is the shell of the entire laundry treatment equipment, laundry treatment drum 2 and detergent box 3 are located in box 1, and the inner cavity of laundry treatment drum 2 is used for placing laundry and washing or drying the laundry.The detergent box 3 can be used to place detergent.

[0076] The fresh air structure 4 is located in the cabinet 1 and outside the entire laundry treatment drum 2, and is used to realize the fresh air function in the laundry treatment drum 2, that is, to dry or purify the laundry treatment drum 2.

[0077] For example, when the fresh air operation is needed, the air in the cabinet 1 can enter the fresh air assembly 42 through the air inlet 421, and then be transported into the laundry treatment drum 2 through the air outlet 422 and the ventilation pipe 41, so as to dry the inner cavity of the laundry treatment drum 2, thereby avoiding the problem that the inner cavity of the laundry treatment drum 2 is prone to breed bacteria or mold due to long-term humid environment, and ensuring the washing effect while avoiding the harm of bacteria and mold residues to human body.

[0078] It should be noted that the air inlet 421 is in communication with the inner cavity of the cabinet 1, so that the air in the cabinet 1 enters the fresh air assembly 42 through the air inlet 421. Specifically, the air in the cabinet 1 can be the air outside the laundry treatment drum 2, or the air in the external environment where the cabinet 1 is located. That is, the external air enters the laundry treatment drum 2 through the fresh air structure 4 to provide fresh air to the laundry treatment drum 2.

[0079] In this embodiment, the fresh air assembly 42 is connected with the cabinet 1 and the detergent box 3 at the same time, so as to realize the double fixation of the fresh air assembly 42. Compared with the way that the fresh air assembly 42 is only connected with the cabinet 1, the fresh air assembly 42 is connected with the cabinet 1 and the detergent box 3 at the same time, which can effectively improve the connection stability of the fresh air assembly 42.

[0080] In addition, since the cabinet 1 is fixed and cannot move, the fresh air assembly 42 is connected with the cabinet 1, and the installation stability of the fresh air assembly 42 is better, so as to effectively prevent the fresh air assembly 42 from falling off.

[0081] The laundry treatment apparatus of this embodiment can be a washing machine, such as a drum washing machine or a pulsator washing machine. In addition, the laundry treatment apparatus can also be a washer-dryer, a laundry care machine, etc., and this embodiment is not limited thereto.

[0082] The laundry treatment device of the embodiment comprises a cabinet 1, a laundry treatment drum 2, a detergent box 3 and a fresh air structure 4, the laundry treatment drum 2, the detergent box 3 and the fresh air structure 4 are all arranged in the cabinet 1, and the fresh air structure 4 and the detergent box 3 are arranged outside the laundry treatment drum 2. By making the fresh air structure 4 comprise a ventilation pipe 41 and a fresh air assembly 42, the air inlet 421 of the fresh air assembly 42 is communicated with the inner cavity of the cabinet 1, and the air outlet 422 of the fresh air assembly 42 is communicated with the inner cavity of the laundry treatment drum 2 through the ventilation pipe 41, so that the air in the cabinet 1 can enter the inner cavity of the laundry treatment drum 2 through the air inlet 421, the air outlet 422 and the ventilation pipe 41, so as to at least dry the inner cavity of the laundry treatment drum 2, thereby avoiding the problem that bacteria and mold are prone to grow in the laundry treatment drum 2 to a certain extent, so as to ensure the washing effect while avoiding the harm to human body caused by the residues of bacteria and mold. Moreover, the fresh air assembly 42 is connected with the cabinet 1 and the detergent box 3 at the same time, so the connection stability of the fresh air structure 4 can be greatly improved to avoid the risk of falling and provide a guarantee for delivering fresh air to the laundry treatment drum 2.

[0083] With reference to Figure 1 , Figure 2 and Figure 4 , in some embodiments, the cabinet 1 has a cross beam 11, and the fresh air assembly 42 is connected with the cross beam 11.

[0084] In specific implementation, the cross beam 11 can be arranged on the cabinet 1, and the cross beam 11 itself can play a role in improving the structural strength of the cabinet 1.

[0085] The fresh air assembly 42 is connected with the cross beam 11, which not only realizes reliable connection between the fresh air assembly 42 and the cabinet 1, but also solves the problem that it is inconvenient to connect and assemble the fresh air assembly 42 due to the thin thickness of the cabinet 1.

[0086] For example, the cross beam 11 can be first fixed on the cabinet 1 by means of screws or other fasteners, and then the fresh air assembly 42 is connected with the cross beam 11.

[0087] For example, the cross beam 11 can be a plate-shaped member.

[0088] With reference to Figures 2 to 5 , in some embodiments, the front side of the laundry treatment drum 2 is provided with a door seal 21, and the door seal 21 has a door seal hole 211 communicated with the inner cavity of the laundry treatment drum 2. The end of the ventilation pipe 41 away from the air outlet 422 is communicated with the door seal hole 211.

[0089] The cross beam 11 extends along the width direction (x direction shown in Figure 2 ) of the cabinet 1, and the cross beam 11 is located above the door seal 21.

[0090] That is, the air discharged through the air outlet 422 is sequentially delivered into the inner cavity of the laundry treatment drum 2 through the ventilation pipe 41 and the door seal hole 211 of the door seal 21, so that the door seal hole 211 on the door seal 21 can be effectively utilized to realize the communication between the ventilation pipe 41 and the inner cavity of the laundry treatment drum 2, and there is no need to additionally provide an opening on the laundry treatment drum 2, thereby saving manufacturing procedures and costs.

[0091] Meanwhile, the cross beam 11 is located above the door seal 21, so that the fresh air assembly 42 connected to the cross beam 11 is relatively close to the door seal 21, so as to facilitate the communication between the ventilation pipe 41 and the door seal hole 211 and the air outlet 422, respectively, so that the length of the ventilation pipe 41 can be effectively shortened, the pipeline in the cabinet 1 is more compact and regular, and the air flow resistance in the ventilation pipe 41 can be reduced to a certain extent, so as to improve the fresh air efficiency.

[0092] Specifically, when the cross beam 11 is arranged above the door seal 21, the cross beam 11 can be connected to the top surface of the front wall of the cabinet 1, so as to facilitate assembly. It should be noted that the front wall of the cabinet 1 refers to the side wall of the laundry treatment device facing the user during use.

[0093] Referring to Figure 1 and Figure 2 , in some embodiments, the detergent box 3 is located on one side of the cabinet 1 in the width direction (referring to the x direction shown in Figure 2 ), and the corner area 12 is defined between the detergent box 3 and the cross beam 11, and the fresh air assembly 42 is located in the corner area 12.

[0094] By arranging the fresh air assembly 42 in the corner area 12 enclosed by the cross beam 11 and the detergent box 3, the space of the corner area 12 is effectively utilized, and the risk of the cabinet 1 being too large due to the arrangement of the fresh air structure 4 can be avoided to a certain extent, which is conducive to the development of the laundry treatment device towards miniaturization while realizing the fresh air function. Moreover, the arrangement position of the fresh air assembly 42 can be close to the cross beam 11 and the detergent box 3 at the same time, so that the assembly is more convenient and stable. In addition, the corner area 12 can play a certain buffering and protection role for the fresh air structure 4. If the cabinet 1 is accidentally collided, since the fresh air structure 4 is located in the corner area, the risk of damage of the fresh air structure 4 due to the collision can be reduced to a certain extent.

[0095] Referring to Figure 1 and Figure 2 , in some embodiments, the detergent box 3 is connected to the cross beam 11.

[0096] In a specific implementation, since the cabinet 1 fixedly installs the cross beam 11, when the detergent box 3 is connected to the cross beam 11, the installation stability of the detergent box 3 is better, and therefore the installation stability of the fresh air assembly 42 connected to the detergent box 3 can be further ensured to effectively prevent the fresh air assembly 42 from falling off.

[0097] Specifically, as shown in Figure 2 The cross beam 11 is clamped in the clamping groove 31, so as to reliably connect the detergent box 3 and the cross beam 11.

[0098] Further, the detergent box 3 and the cross beam 11 can also be fixedly connected by screws or bolts to further improve the connection stability between the detergent box 3 and the cross beam 11.

[0099] Referring to Figure 4 In some embodiments, as shown in the figure, the outer wall of the clothes treatment drum 2 is provided with a return air port 22 communicating with the inner cavity of the clothes treatment drum 2, and the return air port 22 communicates with the detergent box 3.

[0100] That is, the air in the cabinet 1 is sequentially conveyed to the clothes treatment drum 2 through the air inlet port 421, the air outlet port 422, and the ventilation pipe 41, and then flows through the clothes treatment drum 2 and is sequentially discharged from the cabinet 1 through the return air port 22 and the detergent box 3, so as to realize the circulation of the air and accelerate the drying efficiency in the clothes treatment drum 2, and effectively discharge the odor in the clothes treatment drum 2.

[0101] In a specific implementation, the clothes treatment drum 2 includes an inner drum and an outer drum sleeved outside the inner drum, and a water passing gap is formed between the inner drum and the outer drum. Specifically, the return air port 22 can be arranged on the top wall of the outer drum to avoid the washing water or washing foam from being discharged to the outside of the clothes treatment drum 2 through the return air port 22.

[0102] In order to further prevent the washing water or washing foam from entering the return air port 22, a control valve can also be arranged in the return air port 22, and the control valve can control the return air port 22 to be opened when the fresh air structure 4 works.

[0103] Referring to Figures 1 to 5 In some embodiments, as shown in the figure, the cabinet 1 is provided with a support 5, and the fresh air assembly 42 is connected to the cabinet 1 and the detergent box 3 through the support 5.

[0104] In a specific implementation, the fresh air assembly 42 can be first connected to the support 5, and then the support 5 integrated with the fresh air assembly 42 is connected to the cabinet 1 and the detergent box 3, thereby improving the convenience of connection.

[0105] Exemplarily, the support 5 can be made of metal or alloy material to ensure that the support 5 has sufficient structural strength, thereby ensuring assembly stability.

[0106] Referring to Figures 1 to 5 In some embodiments, the support 5 is located between the air inlet 421 and the inner wall of the cabinet 1.

[0107] The support 5 is provided with an opening 51 at a position corresponding to the air inlet 421, and the opening 51 is in communication with the air inlet 421 and the inner cavity of the cabinet 1, respectively.

[0108] In this way, the support 5 can separate the air inlet 421 and the inner wall of the cabinet 1 to a certain extent, so as to ensure that there is sufficient gap between the air inlet 421 and the inner wall of the cabinet 1, that is, the air inlet 421 is not too close to the inner wall of the cabinet 1, so as to reduce the air resistance of air entering the fresh air assembly 42 through the opening 51 and the air inlet 421, thereby improving the fresh air efficiency.

[0109] Referring to Figures 1 to 3 In some embodiments, the side of the support 5 away from the air inlet 421 has a recessed groove 53, the recessed groove 53 is recessed towards the direction of the air inlet 421, and the opening 51 is formed in the groove bottom 531 of the recessed groove 53.

[0110] In this way, the gap between the support 5 and the inner wall of the cabinet 1 can be increased, that is, the gap between the opening 51 and the inner wall of the cabinet 1 is increased, so as to further increase the gap between the air inlet 421 and the inner wall of the cabinet 1, thereby further reducing the air resistance of air entering the fresh air assembly 42 through the air inlet 421, thereby improving the fresh air efficiency.

[0111] Referring to Figures 1 to 3 In some embodiments, the opening 51 is located between the air inlet 421 and the top wall of the cabinet 1, and the opening 51 is arranged towards the top wall of the cabinet 1.

[0112] Exemplarily, the height direction of the laundry treatment drum 2 can refer to the up-down direction shown in Figure 1 Specifically, the support 5 can be arranged above the laundry treatment drum 2 and between the air inlet 421 and the top wall of the cabinet 1, so as to effectively utilize the space between the laundry treatment drum 2 and the top wall of the cabinet 1 to accommodate the support 5.

[0113] At the same time, the opening 51 on the support 5 is towards the top wall of the cabinet 1, for example, the support 5 is arranged in a posture parallel to the top wall of the cabinet 1, so as to fully utilize the internal space of the cabinet 1, and is conducive to the development of small-sized laundry treatment equipment.

[0114] For example, when the support member 5 is positioned above the clothing processing tube 2, the groove 53 is recessed downwards, so that the upper surface of the support member 5 forms the groove 53, thereby increasing the gap between the opening 51 and the top wall of the housing 1, reducing the air resistance of air entering the fresh air assembly 42 through the air inlet 421, and thus improving the fresh air efficiency.

[0115] Alternatively, in other implementations, the support 5 can also be positioned below the clothing processing tube 2.

[0116] Reference Figure 2 and Figure 3 As shown, in some embodiments, the support member 5 has an overlapping portion 52, which overlaps the box body 1 and the detergent box 3 and is connected to the box body 1 and the detergent box 3 respectively.

[0117] This arrangement allows for the pre-fixation of the support component 5 on the housing 1 and the detergent box 3 during assembly, further improving the convenience and efficiency of assembly. Moreover, this arrangement can further enhance the stability of the connection between the support component 5 and the housing 1 and the detergent box 3.

[0118] For example, the overlapping part 52 and the support member 5 can be integrally formed to save manufacturing steps and improve the structural strength of the entire support member 5.

[0119] Reference Figure 2 and Figure 3 As shown, in some embodiments, the support member 5 includes a support body portion 54, and an overlapping portion 52 is disposed at the edge of the support body portion 54. The side of the support body portion 54 facing away from the air inlet 421 has a recessed groove 53, which is recessed toward the air inlet 421.

[0120] That is, the support member 5 includes a support body 54 and an overlapping part 52 disposed on the outer edge of the support body 54.

[0121] By setting the overlapping part 52, the support member 5 can be pre-fixed on the box 1 and the detergent box 3, thereby further improving the convenience and efficiency of assembly. Moreover, this setting can further improve the stability of the connection between the support member 5 and the box 1 and the detergent box 3.

[0122] By providing a recessed groove 53 on the side of the support body 54 facing away from the air inlet 421, the gap between the air inlet 421 and the inner wall of the housing 1 is increased, thereby reducing the air resistance of air entering the fresh air assembly 42 through the air inlet 421 and improving the fresh air efficiency.

[0123] For example, the support body 54 and the overlapping part 52 can be integrally formed to save manufacturing steps and improve the structural strength of the entire support member 5.

[0124] Referring to Figure 2 and Figure 3 In some embodiments, the overlapping portion 52 comprises a first overlapping edge 521 and a second overlapping edge 522 connected with the first overlapping edge 521, and the first overlapping edge 521 and the second overlapping edge 522 are arranged to intersect. The first overlapping edge 521 is arranged to be connected to the cabinet 1, and the second overlapping edge 522 is arranged to be connected to the detergent box 3. The first overlapping edge 521 and the second overlapping edge 522 are integrally formed.

[0125] That is, the support 5 is pre-fixed on the cabinet 1 through the first overlapping edge 521, and is pre-fixed on the detergent box 3 through the second overlapping edge 522, thereby improving the assembly convenience and efficiency of the support 5 with the cabinet 1 and the detergent box 3.

[0126] In addition, by arranging the first overlapping edge 521 and the second overlapping edge 522 to intersect, the assembly convenience of the support 5 with the cabinet 1 and the detergent box 3 can be further improved.

[0127] For example, after the first overlapping edge 521 and the second overlapping edge 522 intersect, they can form an "L" shape as shown in Figure 2 and Figure 3 .

[0128] Specifically, the first overlapping edge 521 and the second overlapping edge 522 can be integrally formed to save manufacturing procedures and improve the structural strength of the entire overlapping portion 52. In addition, the integral overlapping portion 52 can make the fresh air structure 4 more stable, and also make the detergent box 3 more stable.

[0129] Referring to Figure 3 In some embodiments, the support 5 is provided with a first connecting hole 55, the cabinet 1 is provided with a second connecting hole, and the support 5 is connected with the cabinet 1 by a first fastener penetrating the first connecting hole 55 and the second connecting hole, so as to realize reliable connection of the support 5 with the cabinet 1.

[0130] For example, one of the first connecting hole 55 and the second connecting hole can be a threaded hole, and the first fastener can be a screw or a bolt. Alternatively, the first connecting hole 55 and the second connecting hole can both be light holes, and the first fastener can be a fastening pin.

[0131] In addition, the first connecting hole 55 and the second connecting hole can both be provided as two or more, and the first connecting hole 55 and the second connecting hole are one-to-one corresponding, so as to further improve the connection reliability of the support 5 with the cabinet 1 through cooperation of the two or more first connecting holes 55 and the second connecting holes.

[0132] Referring to Figure 3As shown, in some embodiments, the support 5 is provided with a third connecting hole 56, and the detergent box 3 is provided with a fourth connecting hole. The support 5 is connected with the detergent box 3 through a second fastener penetrating the third connecting hole 56 and the fourth connecting hole, so as to realize reliable connection between the support 5 and the detergent box 3.

[0133] For example, one of the third connecting hole 56 and the fourth connecting hole can be a threaded hole, and the second fastener can be a screw or a bolt. Alternatively, the third connecting hole 56 and the fourth connecting hole can both be light holes, and the second fastener can be a fastening pin.

[0134] In addition, the third connecting hole 56 and the fourth connecting hole can both be provided as two or more, and the third connecting hole 56 and the fourth connecting hole are one-to-one corresponding, so as to further improve the connection reliability between the support 5 and the detergent box 3 through cooperation of the two or more third connecting holes 56 and fourth connecting holes.

[0135] In some embodiments, the support 5 is provided with a first positioning part 58, and the box body 1 is provided with a second positioning part. The support 5 is pre-positioned on the box body 1 through cooperation of the first positioning part 58 and the second positioning part.

[0136] That is, after realizing the positioning cooperation between the support 5 and the box body 1 through the first positioning part 58 and the second positioning part, subsequent connection operation is facilitated, and the convenience and efficiency of assembly are improved.

[0137] For example, one of the first positioning part 58 and the second positioning part can be a positioning hole, and the other of the first positioning part 58 and the second positioning part can be a positioning column inserted into cooperation with the positioning hole.

[0138] In some embodiments, the support 5 is provided with a third positioning part 59, and the detergent box 3 is provided with a fourth positioning part. The support 5 is pre-positioned on the detergent box 3 through cooperation of the third positioning part 59 and the fourth positioning part.

[0139] That is, after realizing the positioning cooperation between the support 5 and the detergent box 3 through the third positioning part 59 and the fourth positioning part, subsequent connection operation is facilitated, and the convenience and efficiency of assembly are improved.

[0140] For example, one of the third positioning part 59 and the fourth positioning part can be a positioning hole, and the other of the third positioning part 59 and the fourth positioning part can be a positioning column inserted into cooperation with the positioning hole.

[0141] Reference Figure 3 and Figure 6As shown, in some embodiments, the fresh air assembly 42 is provided with a first assembly hole 423, and the support 5 is provided with a second assembly hole 57. The fresh air assembly 42 is connected to the support 5 by a first assembly member passing through the first assembly hole 423 and the second assembly hole 57, so as to realize reliable connection between the support 5 and the fresh air assembly 42.

[0142] For example, one of the first assembly hole 423 and the second assembly hole 57 can be a threaded hole, and the first assembly member can be a screw or a bolt. Alternatively, the first assembly hole 423 and the second assembly hole 57 can both be light holes, and the first assembly member can be a fastening pin.

[0143] In addition, the first assembly hole 423 and the second assembly hole 57 can both be provided as two or more, and the first assembly hole 423 and the second assembly hole 57 are one-to-one corresponding, so as to further improve the connection reliability between the support 5 and the fresh air assembly 42 by cooperation of the two or more first assembly holes 423 and the second assembly holes 57.

[0144] With reference to Figures 2 to 5 As shown, in some embodiments, the ventilation pipe 41 can be a flexible pipe.

[0145] For example, the ventilation pipe 41 can be a rubber pipe or a silica gel pipe, so as to facilitate adjustment of the running direction of the ventilation pipe 41, thereby facilitating realization of the communication between the air outlet 422 and the clothes treatment drum 2, and saving the internal space of the cabinet 1 to a certain extent, which is conducive to the miniaturization of the clothes treatment equipment.

[0146] Alternatively, in other implementations, the ventilation pipe 41 can also be a corrugated pipe.

[0147] In some embodiments, a first non-flexible pipe 71 can be arranged at the air outlet 422 of the fresh air assembly 42. One end of the first non-flexible pipe 71 is in communication with the air outlet 422, and the other end of the first non-flexible pipe 71 is inserted into the ventilation pipe 41 and in communication with the ventilation pipe 41.

[0148] That is to say, when the ventilation pipe 41 is a flexible pipe, in order to facilitate connection of the flexible pipe on the fresh air assembly 42 to realize communication with the air outlet 422, a first non-flexible pipe can be arranged at the air outlet 422 of the fresh air assembly 42. The rigidity of the first non-flexible pipe is relatively large compared with the ventilation pipe 41, so the first non-flexible pipe can be directly inserted into the ventilation pipe 41, which makes the connection of the two more convenient and stable.

[0149] For example, the first non-flexible pipe 71 can be made of plastic or alloy, so as to ensure that it has sufficient strength.

[0150] Exemplarily, the first non-flexible pipe 71 can be integrally formed with the fresh air assembly 42, or can be separately formed and then clamped or welded together.

[0151] In some embodiments, an end of the ventilation pipe 41 facing the door sealing hole 211 is provided with a second non-flexible pipe, one end of the second non-flexible pipe being in communication with the ventilation pipe 41, and the other end of the second non-flexible pipe being inserted into the door sealing hole 211 and in communication with the door sealing hole 211.

[0152] Since the second non-flexible pipe has a larger rigidity relative to the ventilation pipe 41 and the door seal 21, one end of the second non-flexible pipe is inserted into the ventilation pipe 41, and the other end of the second non-flexible pipe is inserted into the door sealing hole 211 of the door seal 21, thereby facilitating the convenience and stability of the connection between the ventilation pipe 41 and the door seal 21.

[0153] Exemplarily, the second non-flexible pipe can be made of plastic or alloy, etc., to ensure that it has sufficient strength.

[0154] Referring to Figure 3 and Figure 5 , in some embodiments, the fresh air assembly 42 includes a fresh air shell 420 and a fan located in the fresh air shell 420.

[0155] The air inlet 421 and the air outlet 422 are both provided on the fresh air shell 420, so that the air in the cabinet 1 enters the inner cavity of the laundry treatment drum 2 through the air inlet 421, the air outlet 422 and the ventilation pipe 41 under the action of the fan.

[0156] In this way, the rapid flow of air is achieved by the fan to at least dry the inner cavity of the laundry treatment drum 2, thereby avoiding the problem of easy breeding of bacteria and mold in the laundry treatment drum 2 to some extent, so as to ensure the washing effect while avoiding the residual bacteria and mold to cause harm to the human body.

[0157] Specifically, the fresh air shell 420 can be connected with the cabinet 1 and the detergent box 3, so that the connection stability of the fresh air structure 4 can be greatly improved to avoid the risk of falling and provide a guarantee for delivering fresh air to the laundry treatment drum 2.

[0158] Exemplarily, the fan can be a centrifugal fan. In other implementations, the fan can also be an axial flow fan.

[0159] Referring to Figure 8 , Figure 9 and Figure 11 , in some embodiments, the fresh air shell 420 is provided with a one-way structure 6, which is used to communicate the air inlet 421 and the air outlet 422, or to cut off the communication between the air inlet 421 and the air outlet 422.

[0160] That is, by arranging the one-way structure 6 in the fresh air shell 420, the communication between the air inlet 421 and the air outlet 422 can be controlled according to different use scenarios.

[0161] For example, when the fresh air operation is performed, the communication between the air inlet 421 and the air outlet 422 can be controlled by the one-way structure 6 at this time, so that the air enters the fresh air shell 420 through the air inlet 421 and is discharged from the air outlet 422, and finally enters the clothes treatment drum 2, and the inner cavity of the clothes treatment drum 2 is dried.

[0162] For example, when the washing operation is performed, the communication between the air inlet 421 and the air outlet 422 can be controlled by the one-way structure 6 at this time to avoid the risk of overflow of foam or washing water in the clothes treatment drum 2 entering the fresh air shell 420 through the air outlet 422.

[0163] Referring to Figure 9 and Figure 11 In some embodiments, the one-way structure 6 includes a valve piece 61 connected with the inner wall of the fresh air shell 420, and the valve piece 61 is movable relative to the fresh air shell 420 to switch between a first position state and a second position state.

[0164] When the valve piece 61 is in the first position state, the air inlet 421 and the air outlet 422 are in communication. When the valve piece 61 is in the second position state, the air inlet 421 and the air outlet 422 are cut off.

[0165] That is, by arranging the valve piece 61 movable relative to the fresh air shell 420 in the fresh air shell 420, the valve piece 61 can be switched between different position states according to different use scenarios to control the communication or cut-off communication between the air inlet 421 and the air outlet 44.

[0166] For example, when the fresh air operation is performed, the valve piece 61 can be controlled to move to the first position state at this time, and the air inlet 421 and the air outlet 422 are in communication at this time, so that the air enters the fresh air shell 420 through the air inlet 421 and is discharged from the air outlet 422, and finally enters the clothes treatment drum 2, and the inner cavity of the clothes treatment drum 2 is dried.

[0167] For example, when the washing operation is performed, the valve piece 61 can be controlled to move to the second position state at this time, and the air inlet 421 and the air outlet 422 are cut off at this time to avoid the risk of overflow of foam or washing water in the clothes treatment drum 2 entering the fresh air shell 420 through the air outlet 422.

[0168] Referring to Figure 9 andFigure 11 As shown, in some embodiments, the top end of the valve sheet 61 is rotationally connected with the inner wall of the fresh air shell 420, and the bottom end of the valve sheet 61 is formed as a free end, so that the valve sheet 61 is rotated to the first position state under the action of the air entering from the air inlet 421, and can be rotated to the second position state under the action of gravity.

[0169] When fresh air operation is needed, the valve sheet 61 can be rotated to the first position state under the wind force of the air, at this time the air inlet 421 is communicated with the air outlet 422, so that the air entering the fresh air shell 420 from the air inlet 421 is discharged from the air outlet 422 and finally enters the clothes treatment drum 2, and the inner cavity of the clothes treatment drum 2 is dried.

[0170] When washing operation is performed, the valve sheet 61 is then rotated to reset to the second position state under the action of its own gravity, at this time the air inlet 421 is cut off from the air outlet 422, so as to avoid the foam or washing water in the clothes treatment drum 2 from entering the fresh air shell 420 through the air outlet 422 to cause the risk of overflow or water overflow.

[0171] In this way, the communication or cut-off communication between the air inlet 421 and the air outlet 422 is realized by the rotation of the valve sheet 61 itself, which is simple in structure and convenient to control.

[0172] For example, the valve sheet 61 can be made of light and thin PC (PMlycarbMnate, referred to as polycarbonate) material, so that the valve sheet 61 can easily rotate under the wind force of the air, so that the air inlet 421 is communicated with the air outlet 422.

[0173] Of course, in other implementations, the valve sheet 61 can also be arranged to move relative to the fresh air shell 420 under the driving of the driving member to switch between different position states, to realize the communication or cut-off communication between the air inlet 421 and the air outlet 422.

[0174] Referring to Figure 9 , Figure 11 and Figure 13 , in some embodiments, the valve sheet 61 is provided with a rotating lug 611, and the inner wall of the fresh air shell 420 is provided with a hook 427 with a rotating hole 424, the rotating lug 611 is hung in the rotating hole 424 and can rotate relative to the hook 427, so as to realize the rotation of the valve sheet 61 relative to the fresh air shell 420.

[0175] Further, the rotating lug 611 can be provided as two, and the two rotating lugs 611 are arranged on opposite sides of the valve sheet 61 along the rotation axis (y direction, refer to Figure 9 ) of the valve sheet 61, and the hook is two, so as to realize the stable rotation of the valve sheet 61.

[0176] Of course, in other implementations, the one-way structure 6 can also be a one-way electromagnetic valve, etc.

[0177] Referring to Figure 9 and Figure 11 , in some embodiments, the inner wall of the fresh air wind shell 420 is provided with a convex portion 425 extending towards the direction of the inner cavity of the fresh air wind shell 420, and the convex portion 425 is located between the valve sheet 61 and the air inlet 421.

[0178] By arranging the convex portion 425 between the valve sheet 61 and the air inlet 421, the cross section of the internal passage of the fresh air wind shell 420 can be reduced, thereby increasing the flow speed of the air to a certain extent, so that the valve sheet 61 can be smoothly rotated to the first position state under the wind force of the air with a large flow rate, ensuring the effective delivery of fresh air, and also can play a role in gathering the wind to improve the fresh air efficiency.

[0179] For example, the convex portion 425 can be integrally formed with the fresh air wind shell 420 to save manufacturing procedures and improve the structural strength of the entire fresh air wind shell 420. Alternatively, the convex portion 425 and the fresh air wind shell 420 can be separately formed and then clamped together or welded together.

[0180] Referring to Figure 9 and Figure 11 , in some embodiments, the convex portion 425 includes an annular flange extending circumferentially along the inner wall of the fresh air wind shell 420.

[0181] That is, the convex portion 425 has an annular structure with a central hole, which further improves the wind gathering effect and further improves the wind speed, so that the valve sheet 61 can be rotated to the first position state under the wind force of the air with a large flow rate, thereby improving the fresh air efficiency.

[0182] Referring to Figure 9 and Figure 10 , in some embodiments, the side of the convex portion 425 facing the valve sheet 61 forms a contact surface 426, so that the valve sheet 61 is in contact with the contact surface 426 when it is in the second position state.

[0183] That is, when the valve sheet 61 is in the second position state, the valve sheet 61 is in contact with the contact surface 426, which can facilitate the reliable sealing of the internal passage of the fresh air wind shell 420, that is, the reliable cutting off between the air inlet 421 and the air outlet 422.

[0184] Referring to Figure 6As shown, in some embodiments, the fresh air shell 420 comprises a volute 43 and an air outlet shell 44 in communication with the volute 43, and the fan is located in the volute 43, and the air inlet 421 is arranged on the volute 43. The air outlet 422 is arranged on the air outlet shell 44. The air outlet shell 44 has a guide structure 443 thereon to guide the air entering the air outlet shell 44 from the volute 43 to the air outlet 422.

[0185] In this way, the air entering the air outlet shell 44 can flow in the direction of the air outlet 422 under the guidance of the guide structure 443, without backflow, thereby increasing the air outlet of the air outlet 422 and improving the fresh air efficiency.

[0186] In addition, the fresh air shell 420 is arranged to comprise two parts of the volute 43 and the air outlet shell 44, which facilitates the assembly of the fan in the volute 43.

[0187] Specifically, the volute 43 and the air outlet shell 44 can be connected with the support 5 respectively to realize the connection and cooperation with the cabinet 1 and the detergent box 3 through the support 5.

[0188] Specifically, the first assembly hole 423 can be arranged on the volute 43, and the volute 43 can be connected with the support 5 through the first assembly hole 423. The air outlet shell 44 can further be provided with a mounting hole 444 for connecting with the support 5.

[0189] Referring to Figures 6 to 8 As shown, in some embodiments, the air outlet shell 44 has a first air duct section 441 and a second air duct section 442 in communication. One end of the first air duct section 441 is in communication with the volute 43, and the second air duct section 442 is connected to the end of the first air duct section 441 away from the volute 43, and the air outlet 422 is arranged on the second air duct section 442. The guide structure 443 is formed on the first air duct section 441.

[0190] That is, the guide structure 443 is arranged on the first air duct section 441, so that after the air flowing out of the volute 43 enters the air outlet shell 44, it can continue to flow towards the second air duct section 442 under the guidance of the guide structure 443 in the first air duct section 441, and finally be discharged from the air outlet 422.

[0191] That is, by guiding the air through the guide structure 443, the air can be effectively prevented from gathering in the first air duct section 441 or flowing back towards the volute 43, thereby improving the air gathering ability, reducing the flow resistance, increasing the air outlet of the air outlet 422, and improving the fresh air efficiency.

[0192] Referring to Figures 6 to 8As shown, in some embodiments, the inner cavity size of the first air duct section 441 gradually decreases in the direction from the first air duct section 441 to the second air duct section 442 to form the air guide structure 443.

[0193] That is, along Figure 8 As shown in the s direction, the inner cavity size L of the first air duct section 441 gradually decreases, so that the air duct inner wall of the first air duct section 441 facing the fan forms the air guide structure 443. In this way, it is not necessary to additionally provide an air guide structure in the first air duct section 441, thereby simplifying the structure and reducing the cost.

[0194] In other implementations, the air guide structure 443 can also be an air guide plate connected to the inner wall of the air outlet shell 44, which is arranged to be inclined towards the air outlet 422 to guide the air entering the air outlet shell 44 to the air outlet 422.

[0195] Referring to Figure 8 As shown, the one-way structure 6 is located at the joint of the first air duct section 441 and the second air duct section 442 to communicate or cut off the communication between the first air duct section 441 and the second air duct section 442.

[0196] In this way, when fresh air operation is needed, the one-way structure 6 is used to communicate between the first air duct section 441 and the second air duct section 442, so that the air can enter the volute 43 through the air inlet 421, and then continue to flow to the air outlet 422 through the first air duct section 441 and the second air duct section 442, and finally be delivered to the clothes treatment drum 2. When fresh air operation is not needed, the one-way structure 6 is used to cut off the communication between the first air duct section 441 and the second air duct section 442, so that the air inlet 421 and the air outlet 422 are cut off at this time. The whole operation is not only simple and fast, but also simple in structure.
