Description

Technical Field

[0001] This application relates to the technical field of washing machines, and more particularly to a washer-dryer combo. Background Technology

[0002] Most modern washing machines and washer-dryer combos are equipped with an automatic detergent dispensing system. This system cleverly connects a built-in detergent storage container to the washing machine's water inlet line. When the washing machine starts working, the detergent is automatically released from the storage container and smoothly dispensed into the water inlet line, then flows into the washing drum along with the water, bringing great convenience to the user.

[0003] However, while this technology significantly improves ease of use, some shortcomings have gradually emerged in practical applications. Especially during the water intake phase of the washing machine, some detergent often remains in the detergent outlet pipe. When the washing machine completes a washing cycle and enters the rinsing phase, requiring the refilling of clean water, the restarted water intake process inadvertently draws this remaining detergent into the rinsing water. This contaminates the rinsing water again due to the added detergent residue, affecting not only the washing performance but also the overall user experience. Utility Model Content

[0035] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] Most modern washing machines and washer-dryer combos are equipped with an automatic detergent dispensing system. This system cleverly connects a built-in detergent storage container to the washing machine's water inlet line. When the washing machine starts working, the detergent is automatically released from the storage container and smoothly dispensed into the water inlet line, then flows into the washing drum along with the water, bringing great convenience to the user.

[0039] However, while this technology significantly improves ease of use, some shortcomings have gradually emerged in practical applications. Especially during the water intake phase of the washing machine, some detergent often remains in the detergent outlet pipe. When the washing machine completes a washing cycle and enters the rinsing phase, requiring the refilling of clean water, the restarted water intake process inadvertently draws this remaining detergent into the rinsing water. This contaminates the rinsing water again due to the added detergent residue, affecting not only the washing performance but also the overall user experience.

[0040] To overcome the above technical problems, such as Figure 1-9As shown, this embodiment provides a washer-dryer combo, including:

[0041] The outer cylinder 1 has a first opening 11 on its side wall, and the first opening 11 is higher than the highest water level line set by the outer cylinder 1.

[0042] The water inlet box 2 has a water inlet cavity 21 inside and a second opening on one side corresponding to the first opening 11. The water inlet box 2 is installed on the side wall of the outer cylinder 1, and the second opening is aligned with the first opening 11, so that the water inlet cavity 21 communicates with the inner cavity of the outer cylinder 1. The side wall of the water inlet box 2 is also provided with a liquid inlet connector 25 and a water inlet connector 24.

[0043] Detergent adding device 4 is connected to the liquid inlet connector 25;

[0044] An electrically controlled three-way valve 3 is disposed in the water inlet chamber 21. It includes a water inlet 31, a first water outlet 32, and a second water outlet 33. The water inlet 31 is connected to an external water inlet pipe 5 through the water inlet connector 24. The first water outlet 32 ​​faces the inner port of the liquid inlet connector 25, and the second water outlet 33 is offset from the liquid inlet connector 25.

[0045] The outer drum 1 has a first opening 11 on its side wall, and the first opening 11 is higher than the highest water level line set by the outer drum 1. This design is to ensure that the incoming water will never submerge the liquid inlet connector 25 of the detergent adding device 4 inside the water inlet box 2, and to prevent detergent from being abnormally flushed into the outer drum 1.

[0046] The water inlet box 2 has a water inlet cavity 21 inside, and a second opening on one side corresponding to the first opening 11. The water inlet box 2 is installed on the side wall of the outer cylinder 1, with the second opening aligned with the first opening 11, so that the water inlet cavity 21 communicates with the inner cavity of the outer cylinder 1. The side wall of the water inlet box 2 is also provided with a liquid inlet connector 25 and a water inlet connector 24, which are used to connect the detergent adding device 4 and the external water inlet pipe 5, respectively. The water inlet box 2 plays an intermediate transition and distribution role, guiding the water and detergent into the outer cylinder 1 as needed.

[0047] The detergent dispensing device 4 is connected to the liquid inlet connector 25, which automatically adds detergent to the water inlet box 2. When the detergent dispensing function is activated, the detergent dispensing device 4 starts to squeeze detergent into the water inlet box 2. The automated operation of this device greatly improves the convenience of use and reduces manual intervention.

[0048] An electrically controlled three-way valve 3 is installed in the water inlet chamber 21, including a water inlet 31, a first water outlet 32, and a second water outlet 33. The water inlet 31 is connected to the external water inlet pipe 5 through the water inlet connector 24. The first water outlet 32 ​​faces the inner port of the liquid inlet connector 25 and is used to guide the water inlet to the vicinity of the detergent adding device 4 during the washing stage, so that the water inlet washes the detergent squeezed out from the liquid inlet connector 25, mixes it, and flows into the outer drum 1. The second water outlet 33 is offset from the liquid inlet connector 25 and is used to guide the clean water into the outer drum 1 during the rinsing stage, so as to avoid the clean water from contacting the liquid inlet interface with residual detergent and prevent the rinsing clean water from being contaminated.

[0049] Working principle: During the washing stage, when the user turns on the washing function of the washer-dryer combo, the detergent dispensing device 4 starts, dispensing detergent into the water inlet box 2. Simultaneously, water from the external water inlet pipe 5 enters the inlet 31 of the electronically controlled three-way valve 3 through the inlet connector 24. At this time, the first outlet 32 ​​of the electronically controlled three-way valve 3 opens, guiding the water flow to the inner port of the liquid inlet connector 25. The incoming water flow washes away the detergent dispensed from the liquid inlet connector 25, ensuring thorough mixing between the detergent and water. The mixture then flows into the outer drum 1 through the connection between the first opening 11 and the second opening, beginning the washing of the clothes.

[0050] During the rinsing stage, when the washing stage ends and the washer-dryer combo enters the rinsing stage, the detergent dispensing device 4 is closed, and no more detergent is dispensed into the water inlet box 2. At this time, the second outlet 33 of the electronically controlled three-way valve 3 opens, and clean water from the external water inlet pipe 5 enters the electronically controlled three-way valve 3 through the water inlet connector 24 and flows out from the second outlet 33. Because the second outlet 33 is offset from the liquid inlet connector 25, the clean water will not come into contact with the liquid inlet interface where detergent residue remains, thus avoiding the problem of the rinsing water being contaminated by residual detergent, ensuring the cleanliness of the rinsing water, and improving the rinsing effect.

[0051] Based on the solution of this embodiment, at least the following beneficial effects can be achieved:

[0052] 1) Avoid rinsing water contamination: Through the reasonable design of the electronically controlled three-way valve 3, clean water is guided into the outer drum 1 during the rinsing stage, avoiding contact between clean water and residual detergent. This effectively solves the problem of rinsing water being contaminated by residual detergent in the existing technology, and improves the washing quality.

[0053] 2) Improved washing effect: During the washing stage, the incoming water can fully rinse the detergent, so that the detergent and water are evenly mixed and then flow into the outer drum 1, ensuring the effective use of the detergent, improving the washing effect, and better removing stains from clothes.

[0054] 3) Improve user experience: The entire washing and rinsing process is highly automated. Users do not need to manually add detergent or worry about the cleanliness of the rinsing water. The operation is simple, saving time and effort and improving user satisfaction with the washer-dryer combo.

[0055] 4) Reasonable structural design: The height of the first opening 11 of the outer cylinder 1 is set higher than the highest water level line, ensuring that the water inlet will not submerge the liquid inlet connector 25, avoiding abnormal loss of detergent, and also ensuring the stable operation of the entire water inlet system, extending the service life of the washer-dryer combo.

[0056] In one embodiment, reference is made to Figure 9 The first outlet 32 ​​and the second outlet 33 are oriented in opposite directions.

[0057] The first outlet 32 ​​and the second outlet 33 of the electrically controlled three-way valve 3 face opposite directions. This structural design ensures that the two outlets are clearly separated and independent in space, further avoiding the possibility of water coming into contact with residual detergent during the rinsing stage.

[0058] In one embodiment, the electrically controlled three-way valve 3 includes a control rod 34 and an actuator 37. The side wall of the water inlet box 2 is provided with a through hole 23. The actuator 37 is disposed outside the water inlet box 2. The control rod 34 extends out of the water inlet box 2 through the through hole 23 and is connected to the actuator 37.

[0059] The electrically controlled three-way valve 3 includes a control rod 34 and an actuator 37. The control rod 34 extends out of the water inlet box 2 through the through hole 23 on the side wall of the water inlet box 2 and is connected to the actuator 37. The actuator 37 is located outside the water inlet box 2 and is used to control the movement of the control rod 34, thereby realizing the switching of the outlet of the electrically controlled three-way valve 3.

[0060] The control lever 34 and actuator 37 of the electrically controlled three-way valve 3 enable more precise and reliable valve switching. In practical applications, the actuator 37 is connected to the control center of the washer-dryer combo and centrally controlled by the control system. The actuator 37 is located outside the water inlet box 2, avoiding the influence of the humid environment inside the water inlet box 2 on the actuator 37, thus improving the service life and stability of the entire system.

[0061] In one implementation, the housing of the electrically controlled three-way valve 3 includes a protective tube 35, which extends out of the water inlet box 2 through the through hole 23, and the control rod 34 passes through the protective tube 35.

[0062] The protective tube 35 isolates the control lever 34 from the external environment, effectively preventing water, impurities, and other external factors from corroding and interfering with the internal mechanical structure of the control lever 34 and the electrically controlled three-way valve 3. This improves the sealing and protection of the electrically controlled three-way valve 3 and extends its service life. Furthermore, the protective tube 35 provides stable support and guidance for the control lever 34, ensuring that it maintains a precise movement trajectory during operation. This avoids wear or malfunction of the internal mechanical structure of the electrically controlled three-way valve 3 due to shaking or deviation of the control lever 34, thus improving the structural stability and reliability of the entire washer-dryer combo.

[0063] In one embodiment, the protective tube 35 is provided with external threads, and a locking nut 8 is provided on the outside of the water inlet box 2. The locking nut 8 is threadedly connected to the protective tube 35 and abuts against the outer wall of the water inlet box 2. The housing of the electrically controlled three-way valve 3 abuts against the inner wall of the water inlet box 2, so that the electrically controlled three-way valve 3 is fixed on the water inlet box 2.

[0064] Based on this embodiment, when installing the electrically controlled three-way valve 3, the protective tube 35 extends to the outside of the water inlet box 2 through the through hole 23 on the side wall of the water inlet box 2. Then, the locking nut 8 is fitted onto the protective tube 35 and tightened. As the locking nut 8 is tightened, it gradually abuts against the outer wall of the water inlet box 2, while the housing of the electrically controlled three-way valve 3 abuts against the inner wall of the water inlet box 2. This threaded connection and abutment method ensures that the electrically controlled three-way valve 3 is firmly fixed on the water inlet box 2, ensuring that it will not loosen or shift during operation.

[0065] Through the threaded connection between the protective tube 35 and the locking nut 8, and the contact between the locking nut 8 and the outer wall of the water inlet box 2, and the contact between the housing of the electric three-way valve 3 and the inner wall of the water inlet box 2, the electric three-way valve 3 can be firmly installed on the water inlet box 2. This fixing method has high stability and reliability, and can effectively prevent the electric three-way valve 3 from loosening or falling off due to vibration or other external forces during the operation of the washing machine, ensuring the normal operation of the equipment.

[0066] In one embodiment, the housing of the electrically controlled three-way valve 3 is provided with a locking block 36, and the inner wall of the water inlet box 2 is provided with a corresponding locking groove 26. The locking block 36 engages with the locking groove 26 to restrict the movement of the electrically controlled three-way valve 3.

[0067] In this embodiment, a locking block 36 is provided on the housing of the electrically controlled three-way valve 3, while a corresponding locking groove 26 is provided on the inner wall of the water inlet box 2. The locking block 36 and the locking groove 26 are matched in shape and size, enabling a tight engagement. This design, through the cooperation of the locking block 36 and the locking groove 26, effectively restricts the position of the electrically controlled three-way valve 3 within the water inlet box 2, reducing the possibility of shaking and displacement of the electrically controlled three-way valve 3 during operation.

[0068] In one embodiment, the detergent adding device 4 includes a detergent box and a pump 41. The detergent box and the pump 41 are connected by an inlet pipe. The pump 41 is connected to the inlet connector 25 by an outlet pipe 42. The pump 41 can pump detergent into the water inlet box 2.

[0069] When the washing machine needs detergent, the pump 41 is activated, drawing detergent from the detergent box through the inlet pipe and pumping it into the outlet pipe 42. The outlet pipe 42 then delivers the detergent to the inlet connector 25 of the water inlet box 2.

[0070] With precise control of the pump 41, the amount of detergent added can be accurately controlled, ensuring that the appropriate amount of detergent is used in each wash. This avoids detergent waste and prevents incomplete rinsing due to excessive detergent. The entire detergent addition process is fully automated. Users only need to put the detergent into the detergent dispenser before washing, and the washing machine will automatically add the detergent according to the preset program, greatly improving ease of use.

[0071] In one embodiment, combined with Figure 10-11 A diverter 6 is installed at the inner port of the liquid inlet connector 25. The diverter 6 includes a connected insertion tube 61 and a mushroom cap 62. The insertion tube 61 is inserted into the liquid inlet connector 25, and the mushroom cap 62 is provided with a plurality of liquid outlet holes 621.

[0072] When the pump 41 is started, it pumps the detergent from the detergent box into the water inlet box 2. The detergent enters the inlet connector 25 through the outlet pipe 42. The connector 61 of the distributor 6 guides the detergent to the mushroom cap 62. The multiple outlet holes 621 on the mushroom cap 62 evenly disperse the detergent into the water inlet box 2. At the same time, the first outlet 32 ​​of the electronically controlled three-way valve 3 opens. After the water flows into the water inlet chamber 21 from the inlet connector 24, it flows out in the direction of the first outlet 32, rinsing the dispersed detergent and making it fully mixed with the water before flowing into the outer drum 1 to start the washing process.

[0073] Multiple small outlet holes 621 on the distributor 6 can evenly disperse the detergent into the water inlet box 2, so that the detergent and water can be mixed more fully and evenly, improving the utilization efficiency of the detergent and the washing effect.

[0074] In one embodiment, such as Figure 3 As shown, the outer wall of the outer cylinder 1 is provided with a first flange plate 12 surrounding the first opening 11, and the water inlet box 2 is provided with a second flange plate 22 surrounding the second opening. The first flange plate 12 and the second flange plate 22 are connected and locked together.

[0075] When installing the water inlet box 2, align the second flange plate 22 of the water inlet box 2 with the first flange plate 12 of the outer cylinder 1, and then lock the two together by bolts, clips or other suitable connection methods. This connection method ensures a tight fit between the water inlet box 2 and the outer cylinder 1, so that the second opening of the water inlet box 2 is accurately aligned with the first opening 11 of the outer cylinder 1, thereby realizing the communication between the water inlet cavity 21 and the inner cavity of the outer cylinder 1.

[0076] By connecting and locking the first flange plate 12 and the second flange plate 22, the connection between the outer drum 1 and the water inlet box 2 is more secure, which can effectively resist the vibration and water flow impact generated during the operation of the washing machine, ensuring that the two will not loosen or shift, thus improving the stability and reliability of the entire washer-dryer combo.

[0077] In one embodiment, a waterproof ring 7 is provided between the first flange plate 12 and the second flange plate 22.

[0078] When installing the water inlet box 2, align the second flange plate 22 of the water inlet box 2 with the first flange plate 12 of the outer cylinder 1. Place the waterproof ring 7 between the two flange plates. When the two are locked by bolts or other connection methods, the waterproof ring 7 is squeezed and produces elastic deformation, thereby filling the tiny gap between the flange plates and forming a sealing barrier. This sealing barrier can effectively prevent water from leaking from the connection and ensure the sealing between the water inlet box 2 and the outer cylinder 1.

[0079] The waterproof ring 7 significantly improves the sealing performance at the connection between the outer cylinder 1 and the water inlet box 2, effectively preventing water leakage, protecting other internal components of the equipment from water damage, and extending the service life of the equipment.
