DETAILED DESCRIPTION

[0033] In order to make the technical problems solved by the present application, the technical solutions adopted and the technical effects achieved more clear, the technical solutions of the embodiments of the present application are further described in detail below. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work belong to the scope of protection of the present application.

[0034] In the description of the present application, unless explicitly specified and limited, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, it can be the internal communication of two elements or the interaction relationship of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0035] In the present application, unless explicitly specified and limited, the first feature "on" or "under" the second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, the first feature "on", "above" and "above" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "below" and "below" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0036] In the current washing machine or washing and drying integrated machine technical field, although the automatic detergent adding device has been widely used, there are still some places to be improved. The traditional design generally adopts a special mixing chamber in the washing machine, the water inlet pipe passes through the mixing chamber, and the detergent pumping pipe is connected to the mixing chamber. When the washing machine is filled with water, the detergent is pumped into the mixing chamber and mixed with the water flow here, and then the water flow mixed with the detergent is brought into the drum through the water inlet pipe to realize the function of automatic adding of detergent in the washing process.

[0037] However, this traditional structure design has exposed some obvious defects in practical application. First of all, due to the setting of the mixing chamber and the complex connection mode of the water inlet pipe and the detergent pumping pipe, the length of the whole pipeline system is greatly increased. The long pipeline not only occupies a certain space in the washing machine, limits the layout optimization and compact design of the overall structure of other components in the washing machine, but also increases the use of materials, resulting in the rise of production cost.

[0038] To overcome the above technical problems, such as Figures 1-6 As shown, this embodiment provides an automatic detergent dispensing structure, including:

[0039] The washing machine outer drum 1 has a first opening 11 on its side wall or bottom wall, and the first opening 11 is located in the lower half of the washing machine outer drum 1.

[0040] The mixing box 2 has a mixing cavity 21 inside and a second opening on one side corresponding to the first opening 11. The mixing box 2 is installed outside the washing machine drum 1, and the second opening is aligned with the first opening 11, so that the mixing cavity 21 communicates with the inner cavity of the washing machine drum 1. The mixing box 2 is also provided with a filling connector 23 that communicates with the mixing cavity 21.

[0041] Detergent dispensing module 3 is connected to the dispensing connector 23 for dispensing detergent into the mixing chamber 21;

[0042] The stirring module 4 extends into the mixing chamber 21 to stir and mix the liquid in the mixing chamber 21.

[0043] The automatic detergent dispensing structure provided in this embodiment can be applied to washing machines or washer-dryer combos. The outer drum 1 is a fixed structure, and a rotatable drum is provided inside it.

[0044] The washing machine outer drum 1 has a first opening 11 on its lower half of the side or bottom wall, providing an interface for the mixing box 2 to communicate with the inner cavity of the outer drum. The opening's location facilitates the natural flow of water into the mixing box 2 during water intake. When the washing machine is filled with water, water first enters the outer drum 1. Since the first opening 11 is located in the lower half of the outer drum, the water will naturally flow through the first opening 11 and submerge into the mixing chamber 21 of the mixing box 2, providing a basic water environment for subsequent detergent mixing. Preferably, the first opening 11 is located in the bottom one-fifth of the outer drum 1, so that the mixing box 2 can also be submerged when a small amount of water is injected.

[0045] The mixing box 2 is installed outside the outer drum 1 of the washing machine, and its internal mixing chamber 21 is where detergent and water mix. A second opening on one side of the mixing box 2 corresponds to the first opening 11 of the outer drum 1, enabling communication with the inner cavity of the outer drum. The filling connector 23 is designed for easy connection to the detergent filling module 3 to introduce detergent. When the detergent filling module 3 is activated, it pumps detergent through the filling connector 23 into the mixing chamber 21, where it comes into contact with the water already inside.

[0046] The detergent dispensing module 3 is connected to the dispensing connector 23 of the mixing box 2, and is responsible for accurately and quantitatively pumping the detergent into the mixing chamber 21 to ensure that the supply of detergent meets the washing requirements.

[0047] The stirring module 4 extends into the mixing cavity 21, and through the stirring action, the detergent and water are fully mixed, the dissolution process is accelerated, and the detergent is prevented from remaining on the wall surface of the mixing cavity 21 or being unevenly distributed.

[0048] Based on the automatic detergent adding structure provided in the embodiment, at least the following beneficial effects can be achieved:

[0049] 1) Space optimization: The mixing box 2 is installed outside the outer drum 1 of the washing machine, and a complex mixer and pipeline are not required to be arranged inside to connect the water inlet pipeline and the detergent conveying pipeline. The water inlet pipeline can be independently arranged, which greatly reduces the length of the pipeline system, saves the internal space of the washing machine, is beneficial to the layout optimization of other components and the compact design of the overall structure, and makes the washing machine smaller and more beautiful.

[0050] 2) Cost reduction: The pipeline system is simplified, the amount of materials used is reduced, and the production cost is reduced. At the same time, the simplified structure also helps to improve the production efficiency and reduce the assembly difficulty and error rate caused by the complex pipeline connection.

[0051] 3) Improved mixing effect: Through the stirring action of the stirring module 4, the detergent can be more fully dissolved, and the detergent is prevented from remaining on the wall surface of the mixing cavity 21 or being unevenly distributed during the washing process, which improves the utilization rate of the detergent and the washing effect, and makes the clothes washing more uniform and clean. In addition, under the stirring of the stirring module 4, the water in the mixing cavity 21 can flow quickly, and then the water in the mixing cavity 21 and the water in the fixed outer drum can be quickly mixed and exchanged, so that the detergent can be more uniformly and quickly diffused into the fixed outer drum.

[0052] In an embodiment, in combination with Figure 3 The outer drum 1 of the washing machine is provided with a first flange plate 12 surrounding the periphery of the first opening 11, and the mixing box 2 is provided with a second flange plate 22 surrounding the periphery of the second opening. The second flange plate 22 is connected and fixed with the first flange plate 12.

[0053] The outer drum 1 of the washing machine is provided with a first flange plate 12 surrounding the periphery of the first opening 11, and the mixing box 2 is provided with a second flange plate 22 surrounding the periphery of the second opening. The second flange plate 22 is connected and fixed with the first flange plate 12.

[0054] In this embodiment, the washing outer drum 1 and the mixing box 2 are connected by the flange plates, and a firm mechanical connection is formed between them, which can withstand the vibration and water flow impact of the washing machine during operation, so as to ensure that the mixing box 2 will not be loose or displaced, and the stability and reliability of the entire washing machine structure are improved

[0055] Preferably, the first flange plate 12 and the second flange plate 22 are respectively provided with corresponding connecting holes, and the first flange plate 12 and the second flange plate 22 are connected and locked by a bolt and nut assembly.

[0056] In one embodiment, a waterproof ring 6 is arranged between the first flange plate 12 and the second flange plate 22.

[0057] A waterproof ring 6 is arranged between the first flange plate 12 of the washing outer drum 1 and the second flange plate 22 of the mixing box 2. The waterproof ring 6 is usually made of rubber or other elastic materials and has good sealing performance. During assembly, the waterproof ring 6 is placed between the first flange plate 12 and the second flange plate 22, and then the two are connected and fixed by bolts, screws or other fasteners, so that the waterproof ring 6 is compressed between the two and forms a sealing layer.

[0058] The arrangement of the waterproof ring 6 effectively enhances the sealing performance of the connection between the first flange plate 12 and the second flange plate 22, prevents water from seeping out of the connection gap, protects the electrical components and other parts inside the washing machine from water erosion, and improves the safety and reliability of the washing machine.

[0059] In one embodiment, with reference to Figures 4-6 The stirring module 4 includes a motor 42 and a stirrer 41, the stirrer 41 includes a stirring head 411 and a stirring shaft 412 connected thereto; the mixing box 2 is provided with a mounting head 24, the mounting head 24 is provided with a mounting hole matched with the stirring shaft 412, the stirring head 411 is located in the mixing cavity 21, and the stirring shaft 412 extends to the outside of the mixing box 2 through the mounting hole and is connected with the motor 42.

[0060] In this embodiment, the motor 42 serves as a power source and is connected with the stirring head 411 through the stirring shaft 412 to provide power for the operation of the stirrer 41. The stirring head 411 of the stirrer 41 is located in the mixing cavity 21 of the mixing box 2, the stirring shaft 412 extends to the outside of the mixing box 2 through the mounting head 24 of the mixing box 2 and is connected with the motor 42, the mounting head 24 is provided with a mounting hole matched with the stirring shaft 412 to ensure that the stirring shaft 412 is stably installed and rotated. Preferably, a sealing ring is arranged between the mounting head 24 and the stirring shaft 412 to seal and prevent leakage.

[0061] When the detergent needs to be mixed with water, the motor 42 is started to drive the stirring shaft 412 and the stirring head 411 to rotate, and the stirring head 411 stirs the liquid in the mixing cavity 21 to fully mix the detergent with water, accelerate the dissolution and uniform distribution of the detergent.

[0062] The stirring head 411 of the stirrer 41 is placed in the mixing cavity 21, and the stirring shaft 412 extends to the outside to connect the motor 42 through the mounting head 24. This design makes the stirring module 4 and the mixing box 2 closely combined, the overall structure is compact, does not occupy too much extra space, is beneficial to the optimization of the internal layout of the washing machine, and can isolate the motor 42 from water to avoid damage. At the same time, if the stirring module 4 fails or needs to be cleaned and maintained, it is also convenient to disassemble and replace, which reduces the difficulty and cost of maintenance.

[0063] In an embodiment, referring to Figure 4 , the outer wall of the mixing box 2 is provided with a fixing frame 25, and the shell of the motor 42 is provided with a fixing arm 421, and the fixing arm 421 is connected and locked with the fixing frame 25.

[0064] The outer wall of the mixing box 2 is provided with a fixing frame 25, and the shell of the motor 42 is provided with a fixing arm 421, and the fixing arm 421 is connected and locked with the fixing frame 25 through bolts, screws and other fasteners, forming a stable overall structure. This connection method is simple and reliable, and is convenient to install and disassemble.

[0065] Through the connection of the fixing frame 25 and the fixing arm 421, a firm mechanical connection is formed between the motor 42 and the mixing box 2, which can effectively prevent the motor 42 from being displaced or shaken due to vibration or external force during operation, and improve the stability and reliability of the entire stirring module 4.

[0066] In an embodiment, referring to Figure 5 , the filling connector 23 and the mounting head 24 are arranged on two different side walls of the mixing box 2, so that the stirring head 411 in the mixing cavity 21 is aligned with the inner port of the filling connector 23.

[0067] The detergent enters the mixing cavity 21 through the filling connector 23. Since the stirring head 411 is opposite to the inner port of the filling connector 23, when the motor 42 drives the stirring head 411 to rotate, it can immediately stir the entering detergent, so that it is quickly mixed with the water in the mixing cavity 21 to form a uniform washing liquid.

[0068] In an embodiment, the detergent filling module 3 comprises a pump 31, a detergent box, an inlet pipe and an outlet pipe 32, the pump 31 is connected with the detergent box through the inlet pipe, and the pump 31 is connected with the mixing box 2 through the outlet pipe 32. The pump 31 can automatically pump the detergent in the detergent box into the mixing box 2.

[0069] When it is necessary to add detergent, the pump 31 is started to extract the detergent from the detergent box through the inlet pipe, and then pump the detergent through the outlet pipe 32 and finally inject it into the mixing cavity 21 of the mixing box 2. The pump 31 is usually automatically controlled by the control system of the washing machine, and the pumping amount and pumping time are automatically adjusted according to the preset program and the washing requirement, so as to realize the automatic addition of the detergent.

[0070] Based on this embodiment scheme, the entire detergent addition process does not require manual intervention, which improves the automation degree of the washing machine, facilitates the user to use, and is especially suitable for the smart home scene in the modern fast-paced life. The addition amount of the detergent can be accurately controlled by the pump 31, which avoids over-addition or under-addition, saves the amount of the detergent, ensures good washing effect, reduces the use cost and reduces environmental pollution.

[0071] In an embodiment, a one-way valve 5 is further included, which is installed between the filling connector 23 and the outlet pipe 32, and the one-way valve 5 is one-way opened from the outlet pipe 32 to the mixing cavity 21.

[0072] The one-way valve 5 is installed between the filling connector 23 and the outlet pipe 32, specifically at the end of the outlet pipe 32 close to the mixing box 2, and the opening direction of the one-way valve 5 is from the outlet pipe 32 to the mixing cavity 21. The one-way valve 5 is usually composed of a valve body, a valve core and a spring, and the valve core remains in a closed state under the action of the spring. Only when the pump 31 is started and the liquid pressure in the outlet pipe 32 is greater than the sum of the pressure in the mixing cavity 21 and the spring force, the valve core will be opened to allow the liquid to pass through.

[0073] When the pump 31 works to pump the detergent from the detergent box to the mixing box 2 through the outlet pipe 32, the detergent pressure in the outlet pipe 32 makes the valve core of the one-way valve 5 open against the spring force, and the detergent flows smoothly into the mixing cavity 21. When the pump 31 stops working, the liquid pressure in the mixing cavity 21 or external factors may cause the liquid to attempt to flow back from the mixing cavity 21 to the outlet pipe 32, and the one-way valve 5 will automatically close to prevent the backflow of the liquid, ensuring that the detergent can only flow from the outlet pipe 32 to the mixing cavity 21 in one direction.

[0074] In this embodiment, the arrangement of the one-way valve 5 effectively avoids backflow of the detergent from the mixing chamber 21 to the outlet pipe 32 or even the detergent box after pumping, prevents waste of the detergent and possible leakage problems, and maintains the cleanliness and stability of the system. More importantly, after the pump 31 is turned off, the one-way valve 5 can isolate the water in the mixing chamber 21 from the detergent in the outlet pipe 32, that is, during the rinsing process, the detergent in the outlet pipe 32 can be prevented from mixing with the rinsing water, thereby preventing the rinsing water from being contaminated.

[0075] In an embodiment, a grid 7 is arranged in the first opening 11.

[0076] The arrangement of the grid effectively prevents impurities and foreign matter from entering the mixing box 2, avoids damage to key components such as the stirrer 41, prolongs the service life of these components, and improves the reliability and stability of the entire automatic adding structure.

[0077] On the other hand, a washing and drying integrated machine is provided, which comprises the above-described automatic detergent adding structure.

[0078] Similarly, based on the automatic detergent adding structure of the present embodiment, the washing and drying integrated machine of the present embodiment has the advantages of simple pipeline structure and low cost.
