Description

Technical Field

[0001] This application relates to the field of clothing cleaning technology, and in particular to a drawer-type washing module and a washing machine. Background Technology

[0002] Traditional washing machines are divided into front-loading washing machines and top-loading washing machines. They are mainly used for washing medium and large items of clothing. If used for washing small items of clothing (such as socks, underwear, etc.), they consume more water and electricity.

[0003] Currently, there are also small washing machines on the market specifically designed for washing small items of clothing. However, due to the inherent structural limitations of small washing machines, their size is still relatively large, so having both small and traditional washing machines together will take up a significant amount of space. Summary of the Invention

[0004] In view of this, embodiments of this application provide a drawer-type washing module and a washing machine to solve the problem that the coexistence of small washing machines and traditional washing machines would occupy a large amount of space.

The drawer is movably installed inside the housing and is used to hold laundry. The housing or the drawer is provided with a water inlet for injecting water into the drawer and a drain outlet for draining water from the drawer. The flexible pressing member is installed inside the housing, and a portion of the flexible pressing member can move in and out of the drawer under external force to press the laundry placed inside the drawer.

[0006] The beneficial effects of the drawer-type washing module provided in this application embodiment are as follows: Because the drawer-type washing module adopts a drawer-style structure, its size is relatively small. Integrating the drawer-type washing module and the main washing module together does not increase the size of the machine casing, solving the problem of large space occupation caused by the simultaneous existence of small washing machines and traditional washing machines. Furthermore, the flexible pressing component moves in and out of the drawer under external force to press the clothes placed inside, achieving a simulated hand washing effect and enabling damage-free cleaning of clothes.

[0007] In some embodiments, the housing includes a housing body and a cover plate fixed to the housing body, with the edge of the flexible pressing member fixed between the cover plate and the housing body.

[0008] In some embodiments, the cover plate and the flexible pressing member form a first sealed space, and the cover plate is provided with a first air inlet / outlet communicating with the first sealed space, the first air inlet / outlet being used to connect to an air source; or...

[0009] The shell body and the flexible pressing member form a second sealed space. The shell body or the drawer is provided with a second air inlet / outlet that communicates with the second sealed space. The second air inlet / outlet is used to connect to an air source.

[0010] In some embodiments, the drawer-type washing module further includes a corrugated tube and a corrugated tube fixing plate. The first end of the corrugated tube is fixed to the cover plate by the corrugated tube fixing plate, and the second end of the corrugated tube is connected to the flexible pressing member. The corrugated tube and the corrugated tube fixing plate form a third sealed space. The corrugated tube fixing plate has a third air inlet and outlet for connecting to an air source.

[0011] In some embodiments, the drawer-type washing module further includes a driving device disposed on the side of the cover plate facing the flexible pressing member, the driving end of the driving device being connected to the flexible pressing member.

[0012] In some embodiments, the drawer is provided with the drain outlet, and the outer casing is provided with a relief groove to avoid the drain outlet, the relief groove extending along the push-pull direction of the drawer;

[0013] Alternatively, the outer casing may have the drain outlet, the bottom wall of the drawer may have multiple drain holes, and the inner wall of the bottom wall of the outer casing and / or the outer wall of the bottom wall of the drawer may have support protrusions.

[0014] In some embodiments, the drawer is provided with a clothing storage slot surrounded by a side panel, and the opening of the clothing storage slot is arranged correspondingly to the flexible pressing member.

[0015] In some embodiments, the flexible pressing member includes a cylindrical side and a bottom, the bottom being used to press the garment to be washed, and the side having a folded structure.

[0016] In some embodiments, one of the drawer and the outer casing is provided with a snap-fit ​​protrusion, and the other of the drawer and the outer casing is provided with a snap fastener, wherein the snap-fit ​​protrusion and the snap fastener engage in a snap-fit ​​relationship.

[0017] In some embodiments, one of the drawer and the outer casing is provided with a slide groove, and the other of the drawer and the outer casing is provided with a slider, the slide groove extending along the push-pull direction of the drawer, and the slider slidingly engaging with the slide groove.

[0018] The second aspect of this application discloses a washing machine. The washing machine includes a casing, a main washing module, and a drawer-type washing module as described in the first aspect, both the main washing module and the drawer-type washing module being disposed within the casing, with the drawer-type washing module located to one side of the main washing module.

[0019] The washing machine provided in this application has the following advantages: By setting a drawer-type washing module on one side of the main washing module inside the machine casing, dual washing can be achieved in one machine. That is, the main washing module is used to wash medium and large items of clothing, and the drawer-type washing module is used to wash small items of clothing, which saves water and electricity. Because the drawer-type washing module adopts a drawer-type structure, its size is relatively small. Integrating the drawer-type washing module and the main washing module together does not increase the size of the machine casing, solving the problem of large space occupation caused by the coexistence of small washing machines and traditional washing machines. Moreover, the flexible pressing part moves in and out of the drawer under external force to press the clothes placed inside, achieving a simulated hand washing effect, enabling gentle cleaning of clothes.

[0020] In some embodiments, the washing machine further includes a drying module, and the outer casing further has an air inlet for drying air to enter the drawer and an air outlet for drying air to exit the drawer, the air outlet being equipped with a one-way valve; wherein...

[0072] The first aspect of this application proposes a drawer-type washing module. Please refer to... Figures 1 to 3 The drawer-type washing module 10 includes a housing 11, a drawer 12, and a flexible pressing member 13. The housing 11 is fixed to the chassis 20, and the drawer 12 is movably installed inside the housing 11. The drawer 12 is used to hold clothes to be washed. The housing 11 or the drawer 12 is provided with a water inlet 1111 for injecting water into the drawer 12, and a drain outlet 121 for draining water from the drawer 12. The flexible pressing member 13 is installed inside the housing 11, and a portion of the flexible pressing member 13 can move in and out of the drawer 12 under external force to press the clothes to be washed placed inside the drawer 12.

[0073] Optionally, the outer casing 11 is fixed to the chassis 20 by fasteners, such as screws or bolts. Of course, the outer casing 11 can also be fixed to the chassis 20 by snap-fit, adhesive, or other methods.

[0074] Drawer 12 is movably installed inside the outer casing 11. Understandably, drawer 12 can be pushed and pulled inside the outer casing 11. In use, first pull drawer 12 out from the outer casing 11, then put the clothes to be washed into drawer 12, and then push drawer 12 back into the outer casing 11 to wash the clothes.

[0075] The outer casing 11 or drawer 12 is provided with a water inlet 1111 and a drain outlet 121. That is, when washing clothes, water is injected into the drawer 12 through the water inlet 1111, and after washing, the water is drained from the drawer 12 through the drain outlet 121. It is understood that both the water inlet 1111 and the drain outlet 121 can be provided on the outer casing 11; or, both the water inlet 1111 and the drain outlet 121 can be provided on the drawer 12; or, the water inlet 1111 is provided on the outer casing 11 and the drain outlet 121 is provided on the drawer 12; or, the drain outlet 121 is provided on the outer casing 11 and the water inlet 1111 is provided on the drawer 12.

[0076] The flexible pressing element 13 is made of a soft, waterproof material, such as silicone or rubber.

[0077] The flexible pressing part 13 can move in and out of the drawer 12 under the action of external force. It can be understood that the external force can be gas pressure, liquid pressure or the pushing force of the drive device, etc.

[0078] The beneficial effects of the drawer-type washing module 10 provided in this application embodiment are as follows: Because the drawer-type washing module 10 adopts a drawer-type structure, its size is relatively small. Integrating the drawer-type washing module 10 and the main washing module 30 together does not increase the size of the casing 20, solving the problem of large space occupation caused by the simultaneous existence of a small washing machine and a traditional washing machine. Furthermore, the flexible pressing member 13 moves in and out of the drawer 12 under external force to press the clothes placed inside the drawer 12, achieving a simulated hand washing effect and enabling non-destructive cleaning of the clothes.

[0079] Please refer to Figure 2 and Figure 3 In some embodiments, the outer casing 11 includes a casing body 111 and a cover plate 112 fixed to the casing body 111, with the edge of the flexible pressing member 13 fixed between the cover plate 112 and the casing body 111. The top of the casing body 111 is provided with an installation port for inserting the flexible pressing member 13.

[0080] It is understood that the cover plate 112 can be a whole plate that covers the installation opening, and the edge of the flexible pressing member 13 is fixed between the shell body 111 and the edge of the whole plate; or, the cover plate 112 can also be an annular plate, and the edge of the flexible pressing member 13 is fixed between the shell body 111 and the annular plate.

[0081] Optionally, the cover plate 112 is fixed to the shell body 111 by fasteners, such as screws or bolts. Of course, the cover plate 112 can also be fixed to the shell body 111 by snap-fit, adhesive, or other methods.

[0082] Based on the above scheme, the edge of the flexible pressing member 13 is fixed between the cover plate 112 and the shell body 111, which is beneficial to the installation of the flexible pressing member 13.

[0083] Please refer to Figure 1 and Figure 8 In some embodiments, the cover plate 112 and the flexible pressing member 13 form a first sealed space 16. The cover plate 112 is provided with a first air inlet / outlet 1121 that communicates with the first sealed space 16. The first air inlet / outlet 1121 is used to connect to an air source.

[0084] The gas source is a device that can generate pressurized gas. For example, the gas source can be an air pump installed inside the casing 20.

[0085] The cover plate 112 and the flexible pressing member 13 form a first sealed space 16, that is, the cover plate 112 is a whole plate, and the edge of the flexible pressing member 13 and the edge of the cover plate 112 are well sealed.

[0086] The cover plate 112 is provided with a first air inlet / outlet 1121 communicating with the first sealed space 16. The first air inlet / outlet 1121 is connected to an air source. Understandably, the air source can inflate the first sealed space 16 through the first air inlet / outlet 1121. Under positive pressure, part of the flexible pressing member 13 gradually enters the drawer 12, thereby pressing the clothes to be washed inside the drawer 12. Moreover, after pressing, the first sealed space 16 can also expel a portion of the gas through the first air inlet / outlet 1121, so that part of the flexible pressing member 13 no longer presses the clothes to be washed. Through repeated inflation and deflation of the first sealed space 16, the hand washing process is simulated, and the flexible pressing member 13 achieves non-destructive cleaning of the clothes to be washed.

[0087] Please refer to Figure 1 , Figure 9 and Figure 10 In other embodiments, the shell body 111 and the flexible pressing member 13 form a second sealed space 18. The shell body 111 or the drawer 12 is provided with a second air inlet / outlet 1119 that communicates with the second sealed space 18. The second air inlet / outlet 1119 is used to connect to an air source.

[0088] The gas source is a device that can generate pressurized gas. For example, the gas source can be an air pump installed inside the casing 20.

[0089] The shell body 111 and the flexible pressing member 13 form a second sealed space 18, that is, the edge of the flexible pressing member 13 and the shell body 111 are well sealed.

[0090] Understandably, the air source can draw air from the second sealed space 18 through the second air inlet / outlet 1119. Under negative pressure, a portion of the flexible pressing member 13 gradually enters the drawer 12, thereby pressing the clothes to be washed inside the drawer 12. Moreover, after pressing, the second sealed space 18 can also be filled with some gas through the second air inlet / outlet 1119, so that a portion of the flexible pressing member 13 no longer presses the clothes to be washed. By repeatedly drawing and filling the second sealed space 18, the hand washing process is simulated, achieving non-destructive cleaning of the clothes to be washed by the flexible pressing member 13.

[0091] Optionally, the cover plate 112 is a single plate, and the cover plate 112 is provided with multiple first air inlets and outlets 1121; or, the cover plate 112 is an annular plate. In this way, when the flexible pressing member 13 is cleaning the clothes to be washed, there is always air entering and exiting the upper side of the flexible pressing member 13, which is conducive to the partial entry and exit of the flexible pressing member 13 into and out of the drawer 12.

[0092] Please refer to Figures 1 to 3 In some embodiments, the drawer-type washing module 10 further includes a corrugated pipe 14 and a corrugated pipe fixing plate 17. The first end of the corrugated pipe 14 is fixed to the cover plate 112 by the corrugated pipe fixing plate 17, and the second end of the corrugated pipe 14 is connected to the flexible pressing member 13. The corrugated pipe 14 and the corrugated pipe fixing plate 17 form a third sealed space 19. The corrugated pipe fixing plate 17 has a third air inlet and outlet 171, which is used to connect to an air source.

[0093] The gas source is a device that can generate pressurized gas. For example, the gas source can be an air pump installed inside the casing 20.

[0094] The bellows 14 and the bellows fixing plate 17 form a third sealed space 19, that is, the bellows fixing plate 17 is a whole plate, and the edge of the bellows fixing plate 17 is well sealed to the first end of the bellows 14. The second end of the bellows 14 is a closed structure.

[0095] Understandably, the air source can inflate the third sealed space 19 through the third air inlet / outlet 171. Under positive pressure, the bellows 14 extends along its axial direction, and a portion of the flexible pressing member 13 gradually enters the drawer 12, thereby pressing the laundry inside the drawer 12. Moreover, after pressing, the third sealed space 19 can also expel some gas through the third air inlet / outlet 171, so that a portion of the flexible pressing member 13 no longer presses the laundry. Through repeated inflation and deflation of the third sealed space 19, the flexible pressing member 13 achieves non-destructive cleaning of the laundry.

[0096] Optionally, the cover plate 112 is an annular plate, and the cover plate 112 is provided with a first air inlet / outlet 1121. In this way, when the flexible pressing member 13 is cleaning the clothes to be washed, there is always air entering and exiting the upper side of the flexible pressing member 13, which is conducive to the partial entry and exit of the flexible pressing member 13 into and out of the drawer 12.

[0097] In other embodiments, with the bellows 14 in place, the air source can also be connected to the first air inlet / outlet 1121 or the second air inlet / outlet 1119.

[0098] In some other embodiments, the bellows 14 may not be provided. The drawer-type washing module 10 also includes a driving device located on the side of the cover plate 112 facing the flexible pressing member 13, and the driving end of the driving device is connected to the flexible pressing member 13.

[0099] Optionally, the driving device is an electric push rod, the lead screw of which is connected to the flexible pressing member 13, and the lead screw drives part of the flexible pressing member 13 to move in and out of the drawer 12.

[0100] Please refer to Figure 4 , Figure 5 and Figure 7 In some embodiments, the drawer 12 is provided with a drain outlet 121, and the outer casing 11 is provided with a relief groove 1112 to avoid the drain outlet 121. The relief groove 1112 extends along the push-pull direction of the drawer 12.

[0101] Optionally, the drain outlet 121 is located on the bottom wall of the drawer 12, and correspondingly, the clearance groove 1112 is located on the bottom wall of the outer casing 11 to facilitate drainage. Of course, the drain outlet 121 can also be located on the side wall of the drawer 12 and arranged close to the bottom wall of the drawer 12, and correspondingly, the clearance groove 1112 is located on the side wall of the outer casing 11.

[0102] It is understandable that, in the sliding direction of drawer 12, the inner end of the clearance groove 1112 is closed and the outer end is open. In this way, the drain outlet 121 can be integrally formed with drawer 12, or it can be fixed to drawer 12 (by means of threaded connection, snap-fit, adhesive, etc.). Alternatively, in the sliding direction of drawer 12, both ends of the clearance groove 1112 are closed. In this case, the drain outlet 121 needs to be fixed to drawer 12 (by means of threaded connection, snap-fit, adhesive, etc.) after drawer 12 is installed inside outer shell 11.

[0103] Among them, drawer 12 is provided with a sealing part 127, such as Figure 3 and Figure 6 As shown, optionally, the sealing part 127 is a sealing ring groove, and a sealing ring 15 is installed in the sealing ring groove; after the drawer 12 is pushed into the outer shell 11, the sealing ring 15 contacts the annular rib inside the outer shell 11 to achieve a seal.

[0104] When draining water, the water inside drawer 12 is drained directly from drawer 12 to the outside of drawer-type washing module 10, which is beneficial for drainage.

[0105] In other embodiments, please refer to Figures 10 to 12 The outer casing 11 is provided with a drain outlet 121, the bottom wall of the drawer 12 is provided with multiple drain holes 122, and the inner wall surface of the bottom wall of the outer casing 11 and / or the outer wall surface of the bottom wall of the drawer 12 are provided with support protrusions 1113.

[0106] Optionally, the drain outlet 121 is located on the bottom wall of the housing 11 to facilitate drainage. Of course, the drain outlet 121 can also be located on the side wall of the housing 11 and arranged close to the bottom wall of the housing 11.

[0107] Optionally, the inner wall surface of the bottom wall of the outer casing 11 is provided with a support protrusion 1113 so that the bottom wall of the outer casing 11 and the bottom wall of the drawer 12 are spaced a certain distance apart, which is conducive to water flow. Of course, the support protrusion 1113 can also be provided on the outer wall surface of the bottom wall of the drawer 12; or, the support protrusion 1113 can be provided on both the inner wall surface of the bottom wall of the outer casing 11 and the outer wall surface of the bottom wall of the drawer 12.

[0108] Optionally, the bottom wall of the housing 11 is positioned lower than other positions on the bottom wall of the housing 11 to facilitate water flow to the drain 121.

[0109] It is understood that, in the direction of pushing and pulling the drawer 12, the drain outlet 121 can be located in the middle of the bottom wall of the outer casing 11 or at the end of the bottom wall of the outer casing 11.

[0110] It is understood that the support protrusion 1113 can be a straight protrusion or an arc-shaped protrusion extending along the push-pull direction of the drawer 12.

[0111] Among them, drawer 12 is provided with a sealing part 127, such as Figure 10 and Figure 11 As shown, optionally, the sealing part 127 is a sealing ring platform, and a sealing ring 15 is installed on the sealing ring platform; after the drawer 12 is pushed into the outer shell 11, the sealing ring 15 contacts the sealing ring platform on the outer shell 11 to achieve a seal.

[0112] When draining, the water in drawer 12 first flows from drain hole 122 onto the bottom wall of outer casing 11, and then is discharged from drain outlet 121 on outer casing 11.

[0113] Please refer to Figure 3 and Figure 6 In some embodiments, the drawer 12 is provided with a clothing placement slot 124 surrounded by a side panel 123, and the opening of the clothing placement slot 124 is arranged correspondingly to the flexible pressing member 13.

[0114] Optionally, there can be one or more side panels 123. When there is one side panel 123, the shape of the clothing placement slot 124 can be circular, elliptical, etc.; when there are multiple side panels 123, for example, there are four side panels 123, the shape of the clothing placement slot 124 can be rectangular, parallelogram, etc.

[0115] The side panel 123 is a perforated panel, or the side panel 123 is spaced apart from the bottom wall of the drawer 12 to allow water injected from the water inlet 1111 to enter the clothing storage slot 124.

[0116] Optionally, the drain outlet 121 on the drawer 12 is connected to the clothing storage slot 124.

[0117] Since the opening of the clothing placement slot 124 is arranged corresponding to the flexible pressing member 13, the side plate 123 can be used to limit the clothing in the clothing placement slot 124, so that the clothing will not move randomly when the flexible pressing member 13 presses the clothing to be washed, thus effectively cleaning the clothing.

[0118] In other embodiments, the drawer 12 may not have a clothing storage slot 124 formed by the side panel 123. Please refer to [reference needed]. Figure 10 The flexible pressing part 13 can cover the entire drawer 12.

[0119] Please refer to Figure 10 In some embodiments, the flexible pressing member 13 includes a cylindrical side portion 131 and a bottom portion 132, the bottom portion 132 being used to press the clothes to be washed, and the side portion 131 being a folded structure.

[0120] Optionally, the bending position of the side 131 is thinned, and the remaining positions of the side 131 are provided with reinforcing ribs to facilitate the folding of the side 131.

[0121] Optionally, the downward stroke of the bottom 132 is 1 / 2 to 1 / 3 of the height of the flexible pressing member 13 when it is fully extended, in order to facilitate the recovery of the bottom 132.

[0122] Based on the above solution, the side 131 can be folded to reduce the space occupied, thereby reducing the size of the drawer-type washing module 10 and further reducing the space occupied by the drawer-type washing module 10 in the chassis 20.

[0123] Please refer to Figure 6 and Figure 7 In some embodiments, the drawer 12 is provided with a snap-fit ​​protrusion 125, and the outer shell 11 is provided with a buckle 1114, and the snap-fit ​​protrusion 125 and the buckle 1114 are engaged in a snap-fit ​​relationship.

[0124] Optionally, the snap-fit ​​protrusion 125 is provided on the end face of the insertion end of the drawer 12, and the latch 1114 is provided on the inner wall surface of the outer casing 11, which is arranged opposite to the end face of the insertion end of the drawer 12. Of course, the snap-fit ​​protrusion 125 can also be provided in other positions of the drawer 12.

[0125] After the drawer 12 is pushed into the outer casing 11, the drawer 12 is secured inside the outer casing 11 by the engaging engagement of the engaging protrusion 125 and the latch 1114. When the drawer 12 needs to be pulled out, it is only necessary to overcome the engaging force between the engaging protrusion 125 and the latch 1114. This makes pushing in and pulling out the drawer 12 simple and quick.

[0126] In other embodiments, a buckle 1114 may be provided on the drawer 12, and a snap-fit ​​protrusion 125 may be provided on the outer casing 11.

[0127] In some other embodiments, one of the drawer 12 and the chassis 20 is provided with a snap-fit ​​protrusion 125, and the other of the drawer 12 and the chassis 20 is provided with a buckle 1114, and the snap-fit ​​protrusion 125 and the buckle 1114 are engaged in a snap-fit ​​relationship.

[0128] Please refer to Figure 11 and Figure 12 In some embodiments, the outer casing 11 is provided with a slide groove 1115, and the drawer 12 is provided with a slider 126. The slide groove 1115 extends along the push-pull direction of the drawer 12, and the slider 126 slides in cooperation with the slide groove 1115.

[0129] Optionally, the slider 126 is a slider bar that extends along the push-pull direction of the drawer 12. Of course, the slider 126 can also be a slider post, slider block, etc.

[0130] It is understood that the slide groove 1115 can be provided with one, two, three or more, and correspondingly, the sliding member 126 can be provided with one, two, three or more. When there are two slide grooves 1115, the two slide grooves 1115 are respectively provided on the inner sides of two opposite side walls of the outer casing 11.

[0131] The sliding engagement between the sliding member 126 and the slide groove 1115 helps to ensure the relative positional accuracy between the drawer 12 and the outer shell 11, thereby ensuring that the sealing ring 15 is subjected to uniform force and achieving effective sealing of the sealing ring 15.

[0132] In other embodiments, a slider 126 may be provided on the housing 11, and a groove 1115 may be provided on the drawer 12. Alternatively, the groove 1115 and the slider 126 may not be provided, such as... Figure 4 As shown, instead of using the clearance groove 1112 on the outer shell 11 and the drain outlet 121 on the drawer 12 to slide together, the relative position accuracy between the drawer 12 and the outer shell 11 is ensured.

[0133] Please refer to Figure 1 The second aspect of this application discloses a washing machine 100. The washing machine 100 includes a casing 20, a main washing module 30, and a drawer-type washing module 10 as described in the first aspect. Both the main washing module 30 and the drawer-type washing module 10 are disposed inside the casing 20, with the drawer-type washing module 10 located on one side of the main washing module 30.

[0134] Optionally, the chassis 20 has a cuboid structure. For example, the length, width, and height of the chassis 20 are 600mm, 600mm, and 800mm, respectively; the drum diameter of the main washing module 30 is 480-530mm; and the length, width, and height of the drawer-type washing module 10 are 250mm, 150mm, and 80mm, respectively.

[0135] It is understood that the main washing module 30 can be either a drum washing module or a pulsator washing module. When the main washing module 30 is a drum washing module, the drawer-type washing module 10 is located at any position on the radial outer side of the drum. For example, the drawer-type washing module 10 can be located on the upper left, upper right, lower left, or lower right side of the drum washing module.

[0136] The washing machine 100 provided in this application embodiment has the following beneficial effects: By setting a drawer-type washing module 10 on one side of the main washing module 30 inside the casing 20, dual washing can be achieved in one machine. That is, the main washing module 30 is used to wash medium and large items of clothing, and the drawer-type washing module 10 is used to wash small items of clothing, which saves water and electricity. Since the drawer-type washing module 10 adopts a drawer-type structure, its size is small. Integrating the drawer-type washing module 10 and the main washing module 30 together will not increase the size of the casing 20, solving the problem that the coexistence of a small washing machine and a traditional washing machine would occupy a lot of space. Moreover, the flexible pressing member 13 moves in and out of the drawer 12 under the action of external force to press the clothes to be washed inside the drawer 12, realizing hand washing simulation and enabling non-destructive cleaning of the clothes to be washed.

[0137] Please refer to Figure 3 and Figure 13 The washing machine 100 also includes a drying module 80. The outer casing 11 also has an air inlet 1117 for the drying air to enter the drawer 12 and an air outlet 1118 for the drying air to flow out of the drawer 12. The air outlet 1118 is equipped with a one-way valve to ensure that air can exit but not enter at the air outlet 1118, so as to ensure the sealing of the dehydration. There is one drying module 80, which is connected to both the main washing module 30 and the drawer-type washing module 10.

[0138] Specifically, the drying air output from the drying module 80 is controlled by the second switching valve 90 to enter the main washing module 30, or the drawer-type washing module 10, or both the main washing module 30 and the drawer-type washing module 10, in order to dry the clothes.

[0139] Based on the above solution, a drying module 80 is provided, which not only saves costs but also does not increase the space occupied inside the chassis 20.

[0140] In other embodiments, such as Figure 14 As shown, there are two drying modules 80. The two drying modules 80 are connected to the main washing module 30 and the drawer-type washing module 10 respectively. That is, a new drying module 80 is added on the basis of the original drying module 80.

[0141] Please refer to Figure 15 In some embodiments, the washing machine 100 further includes a cleaning liquid self-dispensing module 40 and a water injection pipe 50, the water injection pipe 50 being used to inject water into the main washing module 30 and the drawer-type washing module 10; wherein, the washing machine 100 further includes a first liquid injection pipe 60, the cleaning liquid self-dispensing module 40 being connected to the water injection pipe 50 through the first liquid injection pipe 60.

[0142] The cleaning solution self-dispensing module 40 is used to automatically dispense cleaning solution.

[0143] The cleaning solution self-dispensing module 40 is connected to the water injection pipe 50 via the first injection pipe 60. Specifically, the cleaning solution self-dispensing module 40 first delivers the cleaning solution into the water injection pipe 50 through the first injection pipe 60, and then controls the first switching valve 51 on the water injection pipe 50 to allow the cleaning solution and water to enter the main washing module 30 together, or the drawer-type washing module 10, or both simultaneously. In this case, the first injection port 1116 on the outer casing 11 and the second injection port on the main washing module 30 can be omitted.

[0144] In other embodiments, please refer to Figure 16 Excluding the first injection pipe 60, the washing machine 100 also includes two second injection pipes 70. The cleaning liquid self-dispensing module 40 is connected to the main washing module 30 and the drawer-type washing module 10 through the two second injection pipes 70, respectively. That is, the cleaning liquid self-dispensing module 40 injects cleaning liquid into the main washing module 30 and the drawer-type washing module 10 through the two second injection pipes 70. At this time, a first injection port 1116 needs to be provided on the outer casing 11, and a second injection port needs to be provided on the main washing module 30.

[0145] In other embodiments, the cleaning liquid self-dispensing module 40 and the liquid injection pipe may not be provided; instead, the cleaning liquid may be manually placed into the main washing module 30 and / or the drawer-type washing module 10.

[0146] When using the drawer-type washing module 10, the user first pulls out the drawer 12 and places the clothes to be washed inside. Then, the drawer 12 is pushed back into its original sealed position. Next, water is injected through the water inlet 1111 at the top of the outer casing 11, and cleaning solution enters through the cleaning solution self-dispensing module 40. Then, the bottom 132 of the flexible pressing member 13 changes height under air pressure, pressing down on the clothes inside the drawer 12 to achieve washing. After washing, the water pump operates, generating negative pressure through the drain outlet 121 to draw out the water from the clothes in the drawer 12, achieving dehydration. After dehydration, the drying module 80 sends drying air into the outer casing 11 through the air inlet 1117 and out through the air outlet 1118 to dry the clothes in the drawer 12. This drawer-type washing module 10 has high space utilization and can achieve non-destructive cleaning and drying of small items such as socks and underwear.
