Description

Technical Field

[0001] This utility model relates to the field of clothing processing technology, and in particular to a water inlet switching device and washing equipment for a washing machine. Background Technology

[0002] With the continuous development of washing technology, washing equipment such as washing machines and shoe washing machines have increasingly higher requirements for water intake functions. For example, water is needed to rinse away detergents and fabric softeners used in washing, rinse foam on the inner lid of the washing equipment's drum lid assembly, rinse clothes and shoes, and remove residual foam and other impurities from the washing drum.

[0003] In existing washing equipment, the water inlet device is a single water inlet structure, which can usually only meet the needs of large water volume to achieve water discharge and washing. The direction and spray pattern of water flow during water intake are simple and cannot meet the needs of multiple water flow modes. It cannot rinse and clean the foam in the washing tub and on the inner lid. The function is limited, inconvenient to use, and it is easy to leave foam, lint and other impurities in the clothes and tub, resulting in clothes not being thoroughly cleaned and seriously affecting the user experience.

[0004] Therefore, there is an urgent need for a water inlet switching device and a washing device to solve the above-mentioned problems in the existing technology. Utility Model Content

[0066] Example 1

[0067] like Figure 1 , Figure 2 as well as Figure 3 As shown, this embodiment provides a water inlet switching device 100 for a washing machine, which can realize multiple water inlet modes, enrich the rinsing functions of the washing machine, help improve the cleanliness of clothes, and enhance the user experience. Specifically, the water inlet switching device 100 is installed inside the washing machine and located at the water inlet position. The washing machine is provided with a mounting part for installing the water inlet switching device.

[0068] See Figure 3 , Figure 4 as well as Figure 5 The washing equipment water inlet switching device 100 includes a water inlet switching component 1, which is configured to be movably disposed downstream of the water inlet 201 of the washing equipment, i.e., the water inlet switching component 1 is movable relative to the mounting part. The water inlet switching component 1 is provided with a plurality of non-interconnected water outlet structures 10, and the water flow entering through the water inlet 201 selectively flows out through a portion of the plurality of water outlet structures 10.

[0069] The washing equipment water inlet switching device 100 provided in this application embodiment has a movable water inlet switching component 1 installed downstream of the water inlet 201 of the washing equipment, and multiple non-interconnected water outlet structures 10 installed on the water inlet switching component 1. When the water inlet switching component 1 is driven to move relative to the water inlet 201, the multiple water outlet structures 10 change positions, so that the water flow entering from the water inlet 201 can communicate with different water outlet structures 10, so that the water flow can flow out into the washing equipment through different water outlet structures 10. The water flow mode output by each water outlet structure 10 is different. The water inlet switching component 1 can be switched to different positions in different washing stages to realize multiple water flow modes, enrich the functions of the washing equipment, and improve the user experience.

[0070] In this embodiment, the water flow output from the inlet 201 can only flow out through one of the outlet structures 10. Since the multiple outlet structures 10 are not connected to each other, when water is introduced, only one outlet structure 10 can be connected to the inlet 201 to introduce water, while it is not connected to the other outlet structures 10.

[0071] More specifically, the multiple outlet structures 10 are inconsistent, so that the water flow patterns output through each outlet structure 10 are different. The inconsistency of the multiple outlet structures 10 includes: different cross-sectional shapes of each outlet structure 10, different numbers of water outlet holes included in each outlet structure 10, different sizes of each outlet structure 10, etc., so that the multiple outlet structures 10 have different water outlet velocities, different water outlet directions, different water flow shapes, etc.

[0072] See Figure 2 , Figure 4 as well as Figure 5 The washing equipment water inlet switching device 100 also includes a mounting housing 2. The mounting housing 2 is provided with a water inlet 211 and a water outlet 212. The water inlet 211 is connected to the water inlet 201 of the washing equipment, and the water flowing into the water inlet 201 enters the mounting housing 2 through the water inlet 211. The water inlet switching component 1 is movably disposed in the mounting housing 2. When the water inlet switching component 1 is movable relative to the mounting housing 2, it can selectively connect any water outlet structure 10 to the water outlet 212. The mounting housing 2 provides a mounting base for the water inlet switching component 1. After the water inlet switching component 1 is installed in the mounting housing 2, the mounting housing 2 can be fixedly installed on the mounting part of the washing equipment, simplifying the assembly process and reducing the installation difficulty. On the other hand, the mounting housing 2 can provide a sealed environment for the water inlet switching component 1, ensuring that the water flow output from the water inlet 201 of the washing equipment flows only through the water outlet structure 10 on the water inlet switching component 1 to the water outlet 212, and the water flow output from the water outlet 212 then flows into the interior of the washing equipment.

[0073] Furthermore, the water inlet 211 and water outlet 212 on the housing 2 are arranged in a collinear manner. When one of the outlet structures 10 is directly opposite to and connected to the water outlet 212, the water at the inlet 201 flows out through the water inlet 211, the outlet structure 10 and the water outlet 212 in sequence. The flow path is roughly straight, which can reduce flow resistance, reduce energy consumption and improve water intake efficiency.

[0074] In some other embodiments, instead of providing the mounting housing 2, a sealed cavity can be directly provided on the mounting part of the washing equipment, and a water inlet 211 and a water outlet 212 can be provided through the side wall of the cavity. The water inlet switching component 1 can be movably installed in the cavity, which can also realize multiple water outlet modes.

[0075] like Figure 4 and Figure 5 As shown, the washing equipment water inlet switching device 100 also includes a first driving member 3. The output end of the first driving member 3 is connected to the water inlet switching member 1 to drive the water inlet switching member 1 to rotate. Multiple water outlet structures 10 are distributed circumferentially around the rotation axis of the water inlet switching member 1, that is, multiple water outlet structures 10 are distributed at intervals along the circumference of the water inlet switching member 1. When the first driving member 3 drives the water inlet switching member 1 to rotate, the multiple water outlet structures 10 arranged around the circumference of the water inlet switching member 1 can be connected to the water outlet 212 one by one. The corresponding water outlet structure 10 can be selected to face the water outlet 212 according to the required water outlet mode.

[0076] For example, the first driving component 3 is a small motor, which is inexpensive and easy to control electronically.

[0077] Specifically, in this embodiment, see Figure 5 , Figure 6 , Figure 7 as well as Figure 8 The water inlet switching component 1 includes a rotating shaft 11, a rotating bracket 12, and multiple blades 13. The rotating shaft 11 is connected to the output end of the first driving component 3; the rotating bracket 12 is connected to the rotating shaft 11; the multiple blades 13 are connected to the end of the rotating bracket 12 away from the rotating shaft 11 and are distributed around the circumference of the rotating shaft 11, with at least one outlet structure 10 provided on each blade 13. In this embodiment, each blade 13 is provided with one outlet structure 10; in other embodiments, multiple outlet structures 10 may be provided on each blade 13. The first driving component 3 can drive the rotating shaft 11 to rotate around its own axis, thereby driving the multiple blades 13 to rotate through the rotating bracket 12, so as to rotate the different outlet structures 10 to a position directly opposite the water outlet 212.

[0078] Further, see Figure 9 A water passage area 14 is formed between two adjacent blades 13. When any outlet structure 10 is connected to the water outlet 212, the water inlet 211 can be directly opposite the water passage area 14, so that the water inlet 211 can be connected to the corresponding outlet structure 10 through the water passage area 14. The water flow at the water inlet 211 can flow through the water passage area 14 to the space between multiple blades 13, and then to the outlet structure 10 that is directly opposite and connected to the water outlet 212.

[0079] For example, three blades 13 are provided, and the three blades 13 are evenly distributed around the circumference of the rotating shaft 11, and three water passage areas 14 are formed between them. Each water passage area 14 is directly opposite one of the blades 13, so that the water output from the water inlet 211 can flow smoothly to the outlet structure 10 which is directly opposite the water outlet 212.

[0080] Furthermore, the rotating support 12 includes multiple connecting rods 121, which are distributed circumferentially around the rotating shaft 11. One end of each connecting rod 121 is fixedly connected to the rotating shaft 11, and the other end is connected to a blade 13 to enable the blade 13 to rotate around the rotating shaft 11. For example, when there are three blades 13, there are three corresponding connecting rods 121.

[0081] It is understandable that among the multiple outlet structures 10, only one outlet structure 10 may be connected to the water outlet 212, or two or more may be connected to the water outlet 212. Taking the example of three blades 13, each blade 13 having one outlet structure 10, in this embodiment, when the water inlet switching component 1 is driven to rotate, only one of the outlet structures 10 can be directly opposite the water outlet 212.

[0082] In other embodiments, if the extension length of the water outlet 212 is adaptively increased or more blades 13 are provided, two or more water outlet structures 10 can be simultaneously connected to the water outlet 212.

[0083] It is understandable that the number of blades 13 and the number of connecting rods 121 can be set to two or more, and there is no specific limitation on the number of blades 13 and the number of connecting rods 121 here.

[0084] See Figure 8 One end face of the rotating shaft 11 is provided with a first insertion hole 111, which is used to connect and engage with the output shaft of the first driving member 3 (motor), and is circumferentially limited to the output shaft of the motor so that the motor can drive the rotating shaft 11 to rotate through the output shaft. For example, the cross-sections of the first insertion hole 111 and the output shaft of the motor are both non-circular to achieve circumferential limitation, or the two can also be keyed together to achieve circumferential limitation.

[0085] like Figure 2 , Figure 4 as well as Figure 5 As shown, the mounting housing 2 includes a mounting base 21, a cover 22, and a protective cover 23. The mounting base 21 has a water inlet 211 and a water outlet 212 on its cylindrical portion, with one end closed and the other end open. The water inlet switching component 1 is movably disposed within the mounting base 21, and the cover 22 covers the opening of the mounting base 21 to form a sealed space for accommodating the water inlet switching component 1. Furthermore, the design of the mounting body and cover 22 facilitates the assembly of the water inlet switching device. The protective cover 23 is fixedly connected to the side of the cover 22 facing away from the mounting body, and the protective cover 23 and the cover 22 define an installation space 24 for installing the first driving component 3. The protective cover 23 provides a mounting base for the first driving component 3 and also seals and protects it, providing waterproofing, moisture protection, and impurity prevention.

[0086] See Figure 6 The inner wall of the mounting housing 2 is provided with a mounting shaft 213, which is coaxially inserted and rotatably engaged with the water inlet switching component 1, making the rotation of the water inlet switching component 1 more stable and preventing rotational deviation. Specifically, the bottom wall of the mounting cylinder base 21 is provided with the aforementioned mounting shaft 213, combined with... Figure 7 The rotating shaft 11 is provided with a second insertion hole 112, and the mounting shaft 213 is inserted into the second insertion hole 112 for engagement, and the rotating shaft 11 is rotated in coordination with the mounting shaft 213 through the second insertion hole 112.

[0087] See Figure 10 In this embodiment, the mounting base 21 is configured to pass through the mounting opening 202 of the mounting part of the washing equipment, resulting in a more stable and reliable installation. Combined with... Figure 2 , Figure 4 as well as Figure 5 The mounting base 21 has a flange 214 circumferentially circumferentially around its opening. The flange 214 overlaps the edge area of ​​the mounting port 202, and the cover 22 is in sealing contact with the flange 214. Multiple first connecting lugs 215 are spaced circumferentially along the flange 214, and the first connecting lugs 215 are fixedly connected to the mounting part by first fasteners. The flange 214 overlaps with the edge of the mounting port 202, facilitating the positioning of the water inlet switching device on the mounting part and providing a larger contact area between the mounting cylinder and the mounting part, thus improving connection stability. The sealing contact between the cover 22 and the flange 214 ensures the airtightness of the space where the water inlet switching device 1 is located, and also provides a larger contact area between the cover 22 and the mounting cylinder, improving installation stability.

[0088] Since the plurality of first connecting lugs 215 arranged circumferentially on the flange portion 214 are all fixedly connected to the mounting portion, the entire water inlet switching device can be securely connected to the mounting portion. For example, the first fastener is a screw.

[0089] See Figure 2 The protective cover 23 is provided with a plurality of second connecting lugs 231 spaced apart along the circumference. The second connecting lugs 231 are fixedly connected to the cover 22 by second fasteners, so that a sealed installation space 24 is formed between the protective cover 23 and the cover 22. Alternatively, the second connecting lugs 231 can also be fixedly connected to both the cover 22 and the flange portion 214 by second fasteners.

[0090] Since the multiple second connecting lugs 231 arranged circumferentially on the protective cover 23 are all connected to the cover 22, the connection stability between the protective cover 23 and the cover 22 can be improved. For example, the second fastener is a screw.

[0091] Furthermore, a first sealing ring can be provided between the cover 22 and the flange 214, and a second sealing ring can be sandwiched between the protective cover 23 and the cover 22. Both the first and second sealing rings are rubber rings.

[0092] See Figure 6 The cover 22 is provided with a through hole 221, one end of the rotating shaft 11 passes through the through hole 221 and is connected to the output shaft of the first driving member 3 for transmission.

[0093] Example 2

[0094] This embodiment provides a water inlet switching device 100 for a washing machine, which differs from Embodiment 1.

[0095] The washing equipment water inlet switching device 100 provided in this embodiment includes a first driving member 3. The output end of the first driving member 3 is connected to the water inlet switching member 1 for transmission, so as to drive the water inlet switching member 1 to rotate. Multiple water outlet structures 10 are distributed circumferentially around the rotation axis of the water inlet switching member 1, that is, multiple water outlet structures 10 are distributed at intervals along the circumference of the water inlet switching member 1. When the first driving member 3 drives the water inlet switching member 1 to rotate, the multiple water outlet structures 10 arranged in the circumference of the water inlet switching member 1 can be connected to the water outlet 212 one by one. The corresponding water outlet structure 10 can be selected to be aligned with the water outlet 212 according to the required water outlet mode. For example, the first driving member 3 is a small motor, which has low cost and is easy to implement electrical control.

[0096] Unlike Embodiment 1, the water inlet switching component 1 in this embodiment includes a first switching cylinder, which is located inside the mounting base 21 and connected to the output end of the first driving component 3. Multiple outlet structures 10 are arranged circumferentially on the first switching cylinder. Each outlet structure 10 is provided with a connecting port on the first switching cylinder, which is used to connect the water inlet 211 and the outlet structure 10.

[0097] When it is necessary to switch the water flow mode, the first drive unit 3 is activated. The first drive unit 3 drives the first switching cylinder to rotate inside the mounting housing 2. When the outlet structure 10 of the required water flow mode is directly opposite the water outlet 212, the output end of the first drive unit 3 stops rotating. The connecting port corresponding to the outlet structure 10 is directly opposite the water inlet 211, so that the water flow at the inlet 201 flows through the water inlet 211 and the connecting port to the inside of the first switching cylinder, and then flows out through the outlet structure 10 and the water outlet 212.

[0098] For example, a rotating shaft can be coaxially arranged inside the first switching drum, a bracket is connected to the rotating shaft, the bracket is connected to the inner wall of the first switching drum, and the rotating shaft is connected to the output end of the first driving member 3 for transmission, so that the first driving member 3 can drive the first switching drum to rotate through the rotating shaft and the bracket, thereby switching different water flow modes in different washing stages.

[0099] Example 3

[0100] This embodiment provides a water inlet switching device 100 for a washing equipment, which is a further improvement on the first and second embodiments.

[0101] See Figure 7 and Figure 8The multiple water outlet structures 10 include a first water outlet structure, a second water outlet structure, and a third water outlet structure. The first water outlet structure includes a circular water outlet hole 110; and / or, the second water outlet structure includes a single water outlet strip hole 120 or multiple water outlet strip holes 120 spaced apart or multiple water outlet strip holes 120 arranged in a cross pattern; and / or, the third water outlet structure includes multiple atomizing nozzles 130 spaced apart. The diameter of the circular water outlet hole 110 is larger than the width of the water outlet strip hole 120 and larger than the diameter of the atomizing nozzle 130.

[0102] When the water outlet hole 110 is directly connected to the water outlet 212, water flows out through the water outlet hole 110, which is a high-flow-rate water intake mode, so that the water level of the washing equipment can quickly reach the set washing water level. When the water outlet strip hole 120 is directly connected to the water outlet 212, water flows out through the water outlet strip hole 120. The output water flow is a flat water flow, and the water pressure is increased, which can realize the rinsing function. When the water outlet 212 is connected to multiple atomizing spray holes 130, water flows out through multiple atomizing spray holes 130 to remove foam from clothes and / or inside the drum and / or on shoes by spraying.

[0103] For example, the diameter of the water outlet orifice 110 is between 10 mm and 25 mm, the width of the water outlet strip orifice 120 is between 1 mm and 6 mm, and the diameter of the atomizing spray orifice 130 is less than 1 mm. For instance, the diameter of the water outlet orifice 110 is 20 mm, the width of the water outlet strip orifice 120 is 2 mm, and the diameter of the atomizing spray orifice 130 is 0.5 mm, but it is not limited to these; the specific design can be set according to the requirements.

[0104] Furthermore, the water outlet structure 10 is perpendicular to the axial direction of the inner drum of the washing equipment, or the water outlet structure 10 is set at an angle to the axial direction of the inner drum of the washing equipment, so that the water flow output by the water outlet structure 10 has different flow directions and the water inlet mode is more diverse.

[0105] For example, taking a pulsator washing machine as an example, it includes a top cover assembly that can open and close the clothes inlet. The water outlet strip 120 extends upward at an angle along the opposite side walls in the width direction so that the water outlet direction of the water outlet strip 120 is upward. Thus, when the water outlet strip 120 is directly connected to the water outlet 212, the flat water stream output by the water outlet strip 120 can be sprayed upward to rinse the inner cover of the top cover assembly, thereby cleaning the foam on the inner cover.

[0106] Furthermore, the axial direction of the multiple atomizing nozzles 130, i.e. the water outlet direction, can be perpendicular to the axial direction of the inner drum or tilted downwards, as needed, as long as it can ensure maximum rinsing and cleaning of clothes and / or foam inside the drum and / or shoes.

[0107] Understandably, the first driving component 3 can also drive the water inlet switching component 1 to rotate continuously, so that the multiple water outlet structures 10 on the water inlet switching component 1 periodically connect with the water outlet 212 in sequence, thereby realizing the periodic change of the water inlet mode of the water inlet switching component 1. For example, the water inlet switching component 1 corresponds to three water inlet modes. In one cycle, the three water inlet modes switch sequentially. Driven by the first driving component 3, the water inlet switching component 1 switches sequentially to the first water inlet mode (the high-flow water inlet mode corresponding to the water outlet round hole 110), the second water inlet mode (the water inlet mode for rinsing the inner cover corresponding to the water outlet strip hole 120), the third water inlet mode (the water inlet mode for rinsing clothes foam in the rinsing tube corresponding to the atomizing spray hole 130), and then switches back to the first water inlet mode... repeating the cycle to realize the periodic switching of the water inlet mode.

[0108] Example 4

[0109] This embodiment provides a water inlet switching device 100 for a washing machine, which differs from Embodiments 1, 2, and 3 in that:

[0110] See Figure 11 The washing equipment water inlet switching device 100 also includes a second driving component 4. The output end of the second driving component 4 is connected to the water inlet switching component 1 for transmission, so as to drive the water inlet switching component 1 to move linearly within the mounting housing 2. Multiple water outlet structures 10 are spaced apart on the water inlet switching component 1 along the moving direction of the water inlet switching component 1. When the water inlet switching component 1 moves linearly, the multiple water outlet structures 10 spaced apart along the axial direction on the water inlet switching component 1 are connected one by one to the water outlet 212, realizing multiple water outlet modes.

[0111] When it is necessary to switch the water flow mode, the second drive unit 4 is activated. The second drive unit 4 drives the water inlet switching unit 1 to move in a straight line, specifically along the axial direction of the mounting cylinder 21, until the water outlet structure 10 corresponding to the required water outlet mode is directly connected to the water outlet 212.

[0112] For example, the second driving component 4 is a miniature cylinder, a miniature hydraulic cylinder, or a miniature electric actuator.

[0113] Optionally, a guide shaft protrudes from the inner wall of the mounting housing 2. The guide shaft is slidably inserted into the water inlet switching component 1. When the water inlet switching component 1 moves linearly, the guide shaft slides into the water inlet switching component 1 to precisely guide its movement. Specifically, a guide cylinder is provided at one end of the water inlet switching component 1, and the guide cylinder is slidably inserted into the guide shaft.

[0114] like Figure 11As shown, in this embodiment, the water inlet switching component 1 includes a second switching cylinder 15, which is slidably disposed within the mounting housing 2 and is connected to the output end of the second driving component 4. A water passage hole is provided through the outer wall of the second switching cylinder 15, and the water inlet 211 communicates with the water outlet structure 10 through the water passage hole. By providing the water passage hole on the second switching cylinder 15, water at the water inlet 211 is smoothly introduced into the interior of the second switching cylinder 15 through the water passage hole, and then flows out through the water outlet structure 10, which is directly opposite the water outlet 212.

[0115] For example, multiple outlet structures 10 are arranged opposite to the water passage holes, and the extension length of the water passage holes in the axial direction of the second switching cylinder 15 is greater than the distance between the two farthest outlet structures 10, so that the water passage holes can always connect the water inlet 211 and the outlet structure 10 during the sliding process of the second switching cylinder 15.

[0116] Similar to Embodiment 1, the second drive unit 4 is installed within the installation space 24 defined by the protective cover 23 and the cover 22.

[0117] Example 5

[0118] This embodiment provides a washing device, including a housing, an outer drum, an inner drum, and a washing device water inlet switching device 100 as described in any of the above embodiments. The outer drum is disposed in the housing, and the inner drum is rotatably disposed in the outer drum. A drum cover 200 is connected to the opening of the outer drum, and the drum cover 200 is provided with a water inlet 201. The washing device water inlet switching device 100 is installed on the drum cover 200.

[0119] This washing equipment can specifically be a top-loading washing machine or a top-loading shoe washer. Of course, by adapting some structural changes, it can also be applied to front-loading washing equipment.

[0120] like Figure 1 The diagram shows the installation of the water inlet switching device 100 on the drum cover 200. The drum cover 200 has an installation port 202 on one side of the water inlet 201. The mounting base 21 of the water inlet switching device is inserted into this installation port 202 and fixed with screws or other fasteners.

[0121] See Figure 10 The cylinder cover 200 has multiple lugs 203 arranged circumferentially, and each lug 203 has a connecting hole. By using screws to pass through the connecting holes on the lugs 203, the cylinder cover 200 can be installed at the upper end of the outer cylinder.

[0122] In this washing device, a movable water inlet switching element 1 is provided downstream of the water inlet 201 of its drum cover 200, and multiple non-interconnected water outlet structures 10 are provided on the water inlet switching element 1. When the water inlet switching element 1 is moved relative to the water inlet 201, the multiple water outlet structures 10 change positions, so that the water flow entering from the water inlet 201 can communicate with different water outlet structures 10, allowing the incoming water flow to flow out into the washing device through different water outlet structures 10. Moreover, since the multiple water outlet structures 10 have different shapes, the water flow patterns output through each water outlet structure 10 are different. In different washing stages, the water inlet switching element 1 can be moved to different positions to achieve multiple water flow patterns, making the water inlet rinsing function of the washing device more diverse.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
