Description

Technical Field

[0001] This application belongs to the field of washing machine technology, and in particular relates to a detergent dispenser assembly and a clothing processing device. Background Technology

[0002] To improve the foaming rate of detergent, existing washing machines usually add a Venturi tube to the detergent dispensing line. The negative pressure tube of the Venturi tube is directly connected to the outside atmosphere. When the detergent solution flows through the Venturi tube, a negative pressure is generated, which causes the negative pressure tube to draw in outside gas, thereby increasing the bubble content in the detergent solution and improving the foaming rate of the detergent.

[0003] However, the negative pressure pipe is in direct contact with the outside atmosphere for a long time, which can easily cause the accumulation of dust or impurities, thereby contaminating the detergent solution and affecting the washing effect. Utility Model Content

[0004] This application provides a detergent dispenser assembly and a garment processing device to solve the problem that the negative pressure pipe of the existing washing machine detergent dispensing pipeline, the Chinese-made Churi pipe, is directly connected to the outside atmosphere, which easily causes the accumulation of dust or impurities, thereby contaminating the detergent solution and affecting the washing effect.

[0012] Optionally, the box body includes an upper cover, a lower cover, and an air inlet pipe. The air inlet channel includes a first flow path and a second flow path. The upper cover and the lower cover are sandwiched to form the dispensing pipe and the first flow path. The first flow path connects the negative pressure port and the drain channel. The air inlet pipe is provided with the second flow path, which connects the air inlet and the first flow path.

[0021] The detergent dispenser assembly provided in this application embodiment has a venturi tube in the dispensing pipeline with a negative pressure port connected to the outer cylinder. That is, when the liquid in the dispensing pipeline flows from the inlet to the outlet of the venturi tube, a negative pressure is formed at the negative pressure port, and the gas in the outer cylinder is drawn into the venturi tube from the negative pressure port, thereby increasing the bubble content in the liquid. Furthermore, since the liquid in the outer cylinder usually does not fill the outer cylinder, the negative pressure port is connected to the side of the outer cylinder away from the ground, which not only ensures the air intake requirement of the negative pressure port, but also prevents external dust from entering the negative pressure port, thus ensuring the cleanliness of the negative pressure port.

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0039] This application provides a detergent dispenser assembly and a garment processing device to solve the problem that the negative pressure pipe of the detergent dispensing pipeline in existing washing machines is directly connected to the outside atmosphere, which easily causes the accumulation of dust or impurities, thereby contaminating the detergent solution and affecting the washing effect. The following will be described in conjunction with the accompanying drawings.

[0040] The detergent dispenser assembly provided in this application embodiment is used in clothing processing equipment. Please refer to [link / reference]. Figure 1 and Figure 2 , Figure 1 This is an installation structure diagram of the detergent dispenser assembly provided in an embodiment of this application. Figure 2 This is a schematic diagram showing the connection between the detergent dispenser assembly and the outer drum according to an embodiment of this application. The laundry handling device includes an outer drum 1 and an inner drum, and the detergent dispenser assembly includes a water inlet valve 2 and a dispenser body 3. Please refer to [link / reference]. Figure 3 , Figure 3 This is an exploded view of the upper and lower covers of the detergent dispenser assembly provided in this application embodiment. The dispenser body 3 is provided with a first chamber 34, a dispensing pipe 35, and an air inlet channel 36 at intervals. The dispensing pipe 35 includes a venturi tube 351, which includes a liquid inlet 3511, a liquid outlet 3512, and a negative pressure port 3513. The liquid inlet 3511 is connected to the water inlet valve 2 and / or the first chamber 34, and the liquid outlet 3512 is connected to the inner cylinder. One end of the air inlet channel 36 is connected to the negative pressure port 3513, and the other end is connected to the side of the outer cylinder 1 away from the ground. The first chamber 34 is used to store detergent.

[0041] The detergent dispenser assembly provided in this application embodiment has a negative pressure port 3513 of the venturi tube 351 of the dispensing pipe 35 connected to the outer cylinder 1. That is, when the liquid in the dispensing pipe 35 flows from the inlet 3511 to the outlet 3512 of the venturi tube 351, a negative pressure is formed at the negative pressure port 3513, and the gas in the outer cylinder 1 is drawn into the venturi tube 351 from the negative pressure port 3513, thereby increasing the bubble content in the liquid. Furthermore, since the liquid in the outer cylinder 1 usually does not fill the outer cylinder 1, the negative pressure port 3513 is connected to the side of the outer cylinder 1 away from the ground, which not only ensures the air intake requirement of the negative pressure port 3513, but also prevents external dust from entering the negative pressure port 3513, thus ensuring the cleanliness of the negative pressure port 3513.

[0042] Understandably, the Venturi tube 351 can refer to existing structures, namely, including a contraction section, a throat section, and an expansion section connected in sequence. The inner radial diameter of the contraction section gradually decreases near the throat, and the inner diameter of the throat is the smallest inner diameter within the Venturi tube 351. The inner radial diameter of the expansion section gradually increases away from the throat. When fluid enters the contraction section, the inner diameter of the pipe decreases, the flow velocity increases, and according to Bernoulli's equation, the pressure decreases. At the throat, the flow velocity reaches its maximum value, and the pressure drops to its minimum. When the fluid passes through the expansion section, the inner diameter of the pipe gradually increases, the flow velocity decreases, and the pressure recovers to near the inlet pressure. Specifically, the inlet 3511 is the opening of the contraction section away from the throat, the outlet 3512 is the opening of the expansion section away from the throat, and the negative pressure port 3513 is located at the throat.

[0043] The type of detergent in the first chamber 34 is not further limited here; for example, it can be laundry liquid, fabric softener, disinfectant, bleach, etc.

[0044] Optionally, the air intake channel 36 is connected to the outer cylinder 1 through an air inlet; the box body 3 is also provided with a drain channel and a second chamber 37, the drain channel is connected to the second chamber 37 and the air intake channel 36, and the connection port 362 of the drain channel and the air intake channel 36 is staggered from the air inlet in the horizontal direction.

[0045] By setting up a drain channel, when the Venturi tube 351 fails due to blockage or other reasons, the liquid inside the Venturi tube 351 can flow from the negative pressure port 3513 into the air inlet channel 36, and then flow into the drain channel from the connection port 362 between the drain channel and the air inlet channel 36. From there, it flows into the second chamber 37 of the box body 3. This allows for the recovery of liquid overflowing from the negative pressure port 3513 when the Venturi tube 351 fails, preventing liquid from spreading throughout the box body 3 and causing contamination. Simultaneously, the connection port 362 between the drain channel and the air inlet channel 36 is located between the air inlet and the negative pressure port 3513. Therefore, when liquid flows into the air inlet channel 36, it will first flow into the drain channel from the connection port 362, thus preventing liquid from entering the outer cylinder 1 from the air inlet and contaminating the outer cylinder 1, and avoiding affecting the washing effect inside the inner cylinder.

[0046] Optionally, the negative pressure port 3513 is located on the side of the Venturi tube 351 facing the ground. Therefore, when the Venturi tube 351 fails, the liquid inside the Venturi tube 351 will flow into the air intake channel 36 first from the negative pressure port 3513 due to gravity, preventing the liquid inside the Venturi tube 351 from flowing back from the liquid inlet 3511 and causing contamination of the liquid storage chamber or the water inlet valve 2.

[0047] Optionally, the box body 3 includes an upper cover 31, a lower cover 32, and an air inlet pipe 33. The air inlet channel 36 includes a first flow path and a second flow path. The upper cover 31 and the lower cover 32 are sandwiched to form a dispensing pipe 35 and the first flow path. The first flow path connects to the negative pressure port 3513 and the drain channel. The air inlet pipe 33 has a second flow path inside, which connects to the air inlet and the first flow path. The first flow path and the second flow path are connected through a first opening 361. In the direction of gravity, the first opening 361 is higher than the connecting opening 362. Specifically, the upper cover 31 is provided with a first limiting rib, and the lower cover 32 is provided with a corresponding second limiting rib. After the upper cover 31 and the lower cover 32 are closed, the dispensing pipe 35 and the first flow path are formed by the first limiting rib and the second limiting rib.

[0048] Since the first opening 361 is higher than the connecting opening 362 in the direction of gravity, the flow of liquid in the first flow path to the first opening 361 is further restricted, thus preventing the clothes in the washing drum from being contaminated due to the failure of the venturi tube 351.

[0049] The shape of the first flow path is not further defined here. In some examples, the bottom surface of the first flow path corresponding to the connection port 362 and the negative pressure port 3513 extends horizontally, and the height of the bottom surface of the first flow path corresponding to the connection port 362 and the first opening 361 gradually increases towards the first opening 361. At this time, the liquid level between the connection port 362 and the first opening 361 is higher than the liquid level between the connection port 362 and the negative pressure port 3513. In other examples, the height of the bottom surface of the first flow path corresponding to the connection port 362 and the negative pressure port 3513 gradually decreases towards the connection port 362, and the height of the bottom surface of the first flow path corresponding to the connection port 362 and the first opening 361 gradually increases towards the first opening 361. At this time, the liquid level at the connection port 362 is the lowest.

[0050] In some examples, the intake pipe 33 can be a bellows. The bellows can adapt to the relative displacement between pipes or equipment, reduce vibration and noise, and the bellows can be bent into various shapes as needed for easy installation. The type of bellows is not further limited here, such as annular bellows, V-shaped bellows, spiral bellows and plate bellows.

[0051] Optionally, please refer to Figure 5 , Figure 5 This is a schematic diagram of the structure of the top cover of the detergent dispenser assembly provided in this application embodiment. The Venturi tube 351 is integrally formed on the top cover 31, and the negative pressure port 3513 is opened facing the bottom cover 32. By integrally forming the Venturi tube 351 on the top cover 31, the sealing performance of the Venturi tube 351 is ensured, preventing the poor sealing performance of the Venturi tube 351 due to the split design from affecting the negative pressure suction effect.

[0052] Optionally, please refer to Figure 6, Figure 6 This is a cross-sectional view of the detergent dispenser assembly provided in an embodiment of this application. The second chamber 37 is connected to the outer cylinder 1. That is, the liquid discharged when the Venturi tube 351 in the second chamber 37 fails can be discharged to the outer cylinder 1 as needed for washing. This ensures that even if the Venturi tube 351 fails, detergent solution can still be smoothly added to the outer cylinder 1, guaranteeing washing needs and avoiding the inability to add detergent solution due to the failure of the Venturi tube 351, thus affecting the washing effect. In some examples, the dispenser body 3 also includes a shell and a pull-out drawer disposed within the shell. The upper cover 31 and lower cover 32, when closed, cover the top of the shell. The drawer contains a first chamber 34, and the second chamber 37 can be the space sandwiched between the shell and the drawer.

[0053] Optionally, the dispensing line 35 further includes a first channel 352, which connects to the liquid inlet 3511. The first channel 352 also has a first inlet 3521 and a second inlet. Along the liquid flow direction, the first inlet 3521 is located upstream of the second inlet and is connected to the water inlet valve 2. The detergent cartridge assembly also includes a dispensing pump 4, which connects to the second inlet and the first chamber 34. In some examples, the dispensing pump 4 can be a peristaltic pump.

[0054] By setting the detergent dispensing inlet, i.e. the second inlet, downstream of the dispensing inlet of the water inlet valve 2, i.e. the first inlet 3521, when detergent solution needs to be dispensed, water and detergent are simultaneously dispensed into the first channel 352. The water is used to flush the detergent and mix it to form a detergent solution, which dissolves and foams the detergent, while enhancing the fluidity of the detergent and preventing the detergent from being too viscous to flow in the dispensing pipe 35.

[0055] Furthermore, the detergent in the first chamber 34 is drawn out by the dispensing pump 4 and dispensed into the first channel 352, which facilitates control of the amount of detergent dispensed. The preset volume of detergent can be accurately dispensed according to the washing needs, preventing the detergent from being dispensed too much or too little, which would affect the washing effect. Moreover, the dispensing pump 4 dispenses a fixed amount of detergent into the first channel 352 before rinsing and foaming, avoiding the water flow from directly rinsing the first chamber 34, thereby preventing the detergent in the first chamber 34 from being contaminated by impurities or bacteria in the water, and ensuring the cleanliness of the washing.

[0056] Optionally, please refer to Figure 4 , Figure 4 This is a schematic diagram of the lower cover of the detergent dispenser assembly provided in this embodiment. The detergent dispenser assembly also includes a check valve 5, which is installed at the second inlet. By installing the check valve 5 at the second inlet, the detergent solution is prevented from flowing back from the second inlet to the dispensing pump 4 or the first chamber 34, thus ensuring the cleanliness of the dispensing pump 4 and the first chamber 34.

[0057] As is understandable, a check valve (also known as a one-way valve or check valve) is a device that prevents fluid from flowing backwards in a pipeline. It is mainly used to prevent backflow when the fluid stops flowing or the pressure drops, thereby protecting the system from damage or ensuring its normal operation. The basic working principle of a check valve is to use the fluid pressure difference to control the opening and closing of the valve. When the fluid flows forward, the pressure pushes the valve open; when the fluid stops or flows backwards, the pressure difference decreases or reverses, and the valve automatically closes, preventing backflow. There are various types of check valves, such as lift check valves, rotary check valves, spring-loaded check valves, and float check valves; specific models are not further limited here.

[0058] Optionally, the first chamber 34 includes multiple chambers, and the second inlet is correspondingly provided with multiple inlets. Each first chamber 34 is connected to a second inlet. Specifically, the dispensing pump 4 includes multiple suction ends and discharge ends. Each suction end is connected to a first chamber 34, and each discharge end is connected to a second inlet. That is, a first chamber 34, a suction end, and a second inlet are connected to form a liquid inlet passage. Each first chamber 34 contains different types of detergent, realizing the separate dispensing of different types of detergent and avoiding the cross-contamination between different detergents due to multiple detergents sharing a single liquid inlet passage, which would reduce the washing effect.

[0059] Optionally, please refer to Figure 7 , Figure 7 This is an exploded view of the flow guiding component of the detergent dispenser assembly provided in this embodiment. The detergent dispenser assembly provided in this embodiment also includes a flow guiding component 6, which includes multiple spaced-apart flow paths. One end of the dispensing pump 4 is connected to a first chamber 34 through one flow path, and one end of the dispensing pump 4 is connected to a second inlet through another flow path. In other words, the flow guiding component 6 compensates for the simple connection structure between the dispensing pump 4's dispensing and dispensing ends. When the distance or orientation between the first chamber 34 and the second inlet and the dispensing pump 4's dispensing and dispensing ends is mismatched, the flow guiding component 6 can connect the dispensing pump 4's dispensing and dispensing ends to the first chamber 34 and the second inlet, respectively. The shape of the flow guiding paths is not further limited here.

[0060] Optionally, the dispensing pipe 35 also includes a second channel 353 and a liquid outlet pipe. One end of the second channel 353 is connected to the liquid outlet 3512 of the venturi tube 351, and the other end is connected to the liquid outlet pipe. The end of the liquid outlet pipe away from the second channel 353 is connected to the inner drum. Specifically, the end of the liquid outlet pipe away from the second channel 353 can be embedded in the door seal of the garment processing equipment and oriented towards the inner drum.

[0061] This application also provides a garment processing device, including an outer drum 1, an inner drum, and a detergent dispenser assembly as described above. The type of garment processing device is not further limited here; in some examples, it may be a front-loading washing machine.

[0062] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features.
