[0016] In a third aspect, the present invention provides a washing machine, which includes the aforementioned dispensing system.

[0017] With the above technical solution adopted, the liquid guiding device of this utility model includes a housing, and the interior of the housing is provided with multiple liquid guiding channels. The inlets of the multiple liquid guiding channels are connected to an external water source and / or the outlet of the washing machine's mixing device, and the outlets of the multiple liquid guiding channels are connected to the washing drum of the washing machine and / or the washing machine's dispensing device. This arrangement integrates different water circuit structures into a single liquid guiding device, replacing a large number of messy connecting pipes, making the dispensing system and the internal structure of the washing machine simpler and more organized, improving dispensing efficiency and the utilization rate of the washing machine's internal space.

[0018] Furthermore, the housing of this invention is provided with multiple connecting plates, which are spaced apart along the edge of the housing.

Detailed Implementation

[0037] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0038] It should be noted that in the description of this utility model, terms such as "inner," "outer," "upper," "lower," "top," and "bottom," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0040] As pointed out in the background art, existing dispensing systems suffer from numerous and cluttered pipes, affecting the dispensing efficiency and space utilization of washing machines. This invention provides a liquid guiding device and dispensing system for a washing machine. By integrating various connecting pipes into the liquid guiding device, the device enables long-distance delivery of washing water and detergent while avoiding the chaotic distribution of numerous connecting pipes. This simplifies the internal structure of the dispensing system and the washing machine, improving detergent dispensing efficiency and the internal space utilization of the washing machine.

[0041] For example, in order to meet the diverse needs of users, washing machines are becoming more and more feature-rich, resulting in increasingly complex structures for the dispensing system. At the same time, in order to make the distribution of the dispensing system within the washing machine more reasonable and to improve the liquid storage capacity and mixing effect, some washing machines have adopted a split structure for the dispensing system, which keeps the dispensing port and mixing device away from the drum. This requires the arrangement of a large number of connecting pipes to deliver washing water and washing liquid to the drum according to different task requirements.

[0042] Meanwhile, to facilitate layout and wiring, connecting pipes are usually made of flexible materials, allowing for flexible adjustment of the pipe routing according to the internal structure of the washing machine. However, due to the weak support of flexible materials, a large number of connecting pipes clustered together can cause them to become tangled, and vibrations and collisions can occur during washing machine operation, leading to loosening or damage of the pipes. In addition, the messy distribution of connecting pipes also takes up more space.

[0043] Specifically, such as Figure 1 and Figure 2As shown, the liquid guiding device 1 of this utility model includes a housing, and multiple liquid guiding channels are integrated inside the housing. The number and purpose of the liquid guiding channels can be flexibly set according to functional needs. The inlets of the multiple liquid guiding channels are connected to an external water source and / or the outlet of the mixing device 2 of the washing machine, and the outlets of the multiple liquid guiding channels are connected to the washing drum of the washing machine and / or the liquid dispensing device 3 of the washing machine.

[0044] Preferably, such as Figure 1 As shown, the dispensing system of this utility model includes a mixing device 2, a guiding device 1, and a dispensing device 3. The mixing device 2 is installed on the lower side of the drum and includes a storage chamber and a mixing chamber for storing and mixing the washing liquid. The dispensing device 3 is installed on the upper side of the drum and can distribute the washing water and washing liquid to meet different task modes. The guiding device 1 is located between the mixing device 2 and the dispensing device 3 and is fixed vertically on the washing machine body. The guiding device 1 can be constructed as a water box or a water circuit board, etc. Multiple inlets at its inlet end are connected to multiple outlets of the corresponding flow channels on the mixing device 2, and multiple outlets at its outlet end are connected to multiple inlets of the corresponding flow channels on the dispensing device 3.

[0045] With this configuration, the connection to the mixing device 2 and the dispensing device 3 can be achieved simply by using flexible joints or flexible short pipes at both ends of the shell. This greatly reduces the length and number of connecting pipes, avoids the messy distribution of a large number of connecting pipes, and makes the dispensing system and the internal structure of the washing machine more concise and orderly.

[0046] Preferably, the shell and the reinforcing crossbeam (not shown in the figure) are fixedly connected, which can prevent it from shaking during the operation of the washing machine and ensure its installation stability, effectively improving the dispensing efficiency and the space utilization rate inside the washing machine.

[0047] Preferably, such as Figure 2 As shown, the shell and reinforcing beam of this utility model are fixed together by bolts. Specifically, multiple connecting plates 13 are spaced apart along the edge of the shell, extending outward from the edge of the shell. Each connecting plate 13 has a connecting hole 131, and corresponding threaded holes are provided on the reinforcing beam. The two are connected by bolts. By rationally setting the number and position of the connecting plates 13, the stability of the connection between the shell and the housing is improved, without occupying internal space of the shell. Preferably, one connecting plate 13 is provided on each of the two edges of the shell.

[0048] More preferably, a first positioning structure 132 is also provided on the connecting plate 13, and correspondingly, a second positioning structure (not shown in the figure) is provided at a corresponding position on the reinforcing beam. The first positioning structure 132 and the second positioning structure allow for positioning of the housing on the reinforcing beam before fixing it to the reinforcing beam, thereby improving the installation accuracy of the housing and making assembly simpler and faster. The first positioning structure 132 and the second positioning structure are preferably configured as positioning holes.

[0049] Preferably, such as Figure 2 and Figure 3 As shown, a first limiting structure is provided on the shell, which can cooperate with a second limiting structure on the washing machine body. The limiting structure can be configured in various combinations.

[0050] Preferably, a plurality of horizontally spaced limiting support ribs 14 are provided on the outer wall of the housing near the box body. Each limiting support rib 14 includes a suspension part 141 and an abutment part 142. During assembly, the suspension part 141 is hung on the upper edge of the reinforcing plate, and the abutment part 142 abuts against the side plate of the box body. On the one hand, the housing can be suspended on the reinforcing plate by the limiting support ribs 14 to provide upward support for the housing and reduce the pressure on the screws; on the other hand, the limiting support ribs 14 can also strengthen the side plate of the housing, improving the overall strength of the housing.

[0051] Because the housing will interfere with the damping components of the roller after installation, therefore, Figure 1 As shown, the overall shape of the shell is set as an irregular plate-like structure, with a bend 15 formed in the middle of the plate-like structure to avoid the shock-absorbing components, so that the water channel can bypass the shock-absorbing components.

[0052] In addition to bolts for a rigid connection between the shell and the cabinet, a flexible connecting component 16 is provided. Preferably, the flexible connecting component 16 is a rubber block that can be glued to both the shell and the cabinet at the same time. Combined with the bolted structure, it achieves elastic compression between the two, which helps to reduce the vibration and noise of the washing machine.

[0053] Preferably, such as Figures 4 to 7As shown, the housing is configured as a split structure, including a first housing 11 and a second housing 12 that are detachably and fixedly connected. The first housing 11 has multiple first guide groove structures 111, and the second housing 12 has multiple second guide groove structures 121. The structures and positions of the multiple first guide groove structures 111 and the multiple second guide groove structures 121 correspond to each other, so that multiple liquid guiding channels can be formed after the first housing 11 and the second housing 12 are fastened together. The inlet and outlet of the liquid guiding channels are located at both ends of the first guide groove structures 111. This effectively reduces the processing difficulty and cost of the housing while ensuring the liquid guiding function. Preferably, this application uses a cladding process to achieve bonding and sealing between the first housing 11 and the second housing 12.

[0054] Preferably, such as Figures 4 to 7 The first housing 11 has a first annular sealing groove 112 at its edge, and the second housing 12 has a second annular sealing groove 122 at its edge. The first annular sealing groove 112 and the second annular sealing groove 122, when engaged, form an annular sealing cavity. The liquid guiding device 1 also includes an annular sealing ring (not shown in the figure), which is installed within the annular sealing cavity. Exemplarily, during assembly, the annular sealing ring is first pressed into the first sealing groove, and then the second sealing groove is engaged with the first sealing groove, thus pressing the sealing cavity tightly against the annular sealing ring.

[0055] This design improves the airtightness of the casing, preventing air and water leakage that could affect the delivery effect.

[0056] Preferably, the present invention further includes a first positioning groove 113 on the first housing 11 and a second positioning groove 123 on the second housing 12. The first positioning groove 113 and the second positioning groove 123 can be engaged to form a positioning cavity. The liquid guiding device 1 also includes a positioning block. The shape of the positioning block is the same as that of the positioning cavity. During assembly, the positioning block is installed in the positioning cavity, which enables it to simultaneously engage with the first positioning groove 113 and the second positioning groove 123 to fix the relative positions of the first housing 11 and the second housing 12, prevent misalignment during connection, and play a positioning role, thereby ensuring the positional accuracy and assembly quality between the two.

[0057] Furthermore, the present invention provides a dispensing system based on the above-mentioned liquid guiding device 1, including the above-mentioned liquid guiding device 1, liquid mixing device 2 and liquid dispensing device 3. The liquid mixing device 2 includes multiple pure water channels and / or mixed liquid channels, and the liquid dispensing device 3 is provided with multiple liquid dispensing channels. The inlets of the multiple liquid guiding channels are respectively connected to the outlets of the multiple pure water channels and / or mixed liquid channels, and the outlets of the multiple liquid guiding channels are respectively connected to the inlets of the multiple liquid dispensing channels.

[0058] In a preferred embodiment of the present invention, the liquid guiding device of the present invention includes, but is not limited to, a residual water drainage channel, a spray channel, a cleansing channel, a condensation channel, and a rinsing channel. Correspondingly, the mixing device 2 and the water distribution device are also provided with corresponding and connected channels, thereby meeting the water supply and liquid supply needs of the washing machine in different modes.

[0059] Finally, the washing machine provided by this invention, based on the above-mentioned dispensing system, possesses the technical effects of the above-mentioned dispensing system. Compared with the washing machine before the improvement, the washing machine of this invention has multiple functional modes, improves the dispensing efficiency of washing liquid and washing water, as well as the space utilization rate inside the washing machine, and avoids positional interference between various components.

[0060] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
