Description

Technical Field

[0001] This utility model relates to the field of washing equipment technology, and more specifically, to a three-way connector and washing equipment. Background Technology

[0002] In the field of laundry equipment, the circulating spray function is an important technology widely used in washing and rinsing processes to improve cleaning results and user experience. The function of the circulating spray is to evenly spray the liquid inside the washing chamber onto the surface of the clothes, ensuring that the clothes are fully immersed in the liquid. This improves efficiency during washing or rinsing, resulting in cleaner clothes and rinses, while also saving water and electricity.

[0034] This embodiment proposes a tee connector 10, such as... Figures 1-5 As shown, the tee connector 10 includes a connector body 1 and a flow guiding structure. The connector body 1 is provided with a first fluid inlet 111, a second fluid inlet 121, and a fluid outlet 112. The connector body 1 includes a first pipe section 11 and a second pipe section 12 connected to each other. Preferably, the first pipe section 11 and the second pipe section 12 are straight pipes or near-straight pipes to reduce fluid flow resistance.

[0035] The first pipe section 11 has a connecting port 113 on its side wall. A first fluid inlet 111 and a fluid outlet 112 are located at opposite ends of the first pipe section 11. A second fluid inlet 121 is located at the end of the second pipe section 12 furthest from the connecting port 113, and the second pipe section 12 is inclined towards the first fluid inlet 111. In this case, the overall shape of the tee connector 10 is Y-shaped. The second pipe section 12 is connected to the first pipe section 11 through the connecting port 113. The first pipe section 11 and the second pipe section 12 can be directly connected or indirectly connected through a transition pipe section. Preferably, the connector body 1 also includes a bend section 13, located between the first pipe section 11 and the second pipe section 12. The bend section 13 serves as a transition pipe section connecting the second pipe section 12 and the first pipe section 11, reducing the flow resistance of fluid entering the first pipe section 11 from the second pipe section 12.

[0036] The flow guiding structure is located inside the first pipe section 11 and near the connecting port 113. The flow guiding structure is used to guide the fluid from the second pipe section 12 to flow vertically or nearly vertically into the fluid in the first pipe section 11, so as to increase the impact force when the fluid in the first pipe section 11 and the fluid in the second pipe section 12 meet at the connecting port 113. When detergent is dissolved in the fluid in the first pipe section 11 and / or the second pipe section 12, the washing and water mixing effect can be effectively improved, and the foaming effect of the detergent can also be improved, thereby improving the washing efficiency and cleaning effect.

[0037] In one example, such as Figure 3As shown, the connecting port 113 includes a first end 1131 near the fluid outlet 112, and the flow guiding structure includes a flow guide plate 2, which includes a first side 21 and a second side 22. The first side 21 is connected to the first end 1131, and the second side 22 extends from the first end 1131 toward the first fluid inlet 111. The second side 22 is spaced apart from the inner wall surface of the first pipe section 11, and an arc-shaped plate with a concave surface facing the first fluid inlet 111 is formed between the first side 21 and the second side 22. The arc-shaped plate has at least one first flow passage 23.

[0038] The arc-shaped plate divides the first pipe section 11 into a first channel and a second channel. The first channel is close to the connecting port 113, located on the concave side of the arc-shaped plate, while the second channel is away from the connecting port 113, located on the convex side of the arc-shaped plate. Part of the fluid from the first fluid inlet 111 flows through the second channel to the fluid outlet 112, while the other part enters the first channel. Under the action of the arc-shaped plate, the fluid from the second pipe section 12 flows vertically or nearly vertically towards the fluid located on the concave side of the arc-shaped plate, and then flows with the fluid on the concave side of the arc-shaped plate through the first flow passage 23 to the fluid outlet 112. According to Bernoulli's principle, the fluid velocity and pressure increase after flowing out of the first flow passage 23, thereby increasing the velocity and pressure at the fluid outlet 112. When the fluid flowing out of the fluid outlet 112 flows into the spray device 60, the spray speed and spray pressure can be effectively increased. In washing equipment applications, this can effectively increase the spray range and improve the cleaning effect.

[0039] Preferably, the arc of the arc plate is in the range of 60° to 90°, so as to ensure the flow guiding effect while also ensuring that the gap between the second side 22 of the arc plate and the inner wall of the first pipe section 11 is large, so that the fluid can flow smoothly into the first channel and the second channel.

[0040] Preferably, the connecting port 113 includes a second end 1132 disposed near the first fluid inlet 111, and the second side 22 of the arc-shaped plate extends to a position flush with or nearly flush with the second section, so as to ensure the height difference between the second fluid inlet 121 and the second side 22, and reduce the backflow effect of the water flow from the first fluid inlet 111 on the water flow from the second fluid inlet 121 at the connecting port 113.

[0041] Preferred, such as Figure 3 and Figure 4 As shown, the inlet of the first flow channel 23 faces the first fluid inlet 111, and the outlet of the first flow channel 23 faces the fluid outlet 112, which allows the fluid on the concave side of the arc plate to flow more smoothly into the first flow channel 23.

[0042] Preferably, the arc-shaped plate includes a first part 201 and a second part 202. The first part 201 is disposed near the first side 21, and the second part 202 is disposed near the second side 22. The first flow passage 23 is opened in the second part 202. Thus, the first part 201 mainly serves to guide the fluid from the second pipe section 12 to flow towards the concave side of the arc-shaped plate in a vertical or approximately vertical direction. The second part 202 mainly serves to guide the fully mixed fluid on the concave side of the arc-shaped plate to flow smoothly to the fluid outlet 112, and to pressurize and accelerate the fluid.

[0043] In one alternative implementation, such as Figure 4 and Figure 5 As shown, the cross-sectional area of ​​the first pipe section 11 is S1, and S1 refers to... Figure 5 The area enclosed by the red circle. The projected area of ​​the guide vane 2 in the cross-sectional direction of the first pipe section 11 is S2, S2 refers to... Figure 5 The area enclosed by the green circle. S2 / S1 < 1 / 2, to obtain the best flow guidance and pressurization effect. The specific value can be calculated based on the flow rate of the circulating pump 70 and the water pressure from the first fluid inlet 111.

[0044] In one optional implementation, the connecting port 113 includes a second end 1132 near the first fluid inlet 111. The tee connector 10 also includes a baffle 3, one end of which is disposed at the first end 1131, and the other end of which extends towards the second end 1132 and is spaced apart from the second end 1132. A second flow channel is formed between the baffle 3 and the second end 1132, and the second flow channel connects the second pipe section 12 and the first pipe section 11. In this embodiment, by setting the baffle 3, the excessive fluid pressure in the first pipe section 11 can be further avoided from causing the water flow to backflow into the second pipe section 12. When the pipe connected to the second pipe section 12 is connected to a water pump, the impact on the water pump can be reduced.

[0045] In one alternative implementation, such as Figure 2 As shown, the axial angle between the second pipe section 12 and the first pipe section 11 is A, and the range of A is 30°-60°. This avoids excessive water flow resistance due to an excessively large angle, and at the same time further reduces the back pressure of the water flow in the second pipe section 12 on the water flow in the first pipe section 11.

[0046] In one alternative implementation, such as Figures 1-3 As shown, the tee joint 10 also includes a bend section 13, which is located between the first pipe section 11 and the second pipe section 12. The bend section 13 has an arc-shaped wall 131 on the side near the fluid outlet 112. The arc-shaped wall 131 is connected to the first end 1131 and is adapted to the extension direction of the arc plate to further reduce the fluid resistance of the airflow in the second pipe section 12 into the first pipe section 11.

[0047] In one alternative implementation, such as Figure 1 and Figure 2 As shown, the straight pipe section is also equipped with a limiting structure 4 and / or a fixing structure 5. The limiting structure 4 is, for example, a limiting rib, and the fixing structure 5 is, for example, a fixing column, with screw holes inside the fixing column. Both the limiting structure 4 and the fixing structure 5 can improve the assembly reliability between the tee joint 10 and the equipment on which it is installed.

[0048] In this embodiment, the three-way connector 10, by setting a flow guiding structure, can guide the fluid in the second pipe section 12 to flow towards the first pipe section 11 in a vertical or near-vertical direction, thereby increasing the impact force between the fluid in the second pipe section 12 and the fluid in the first pipe section 11 at the connecting port 113. When one of the fluids in the two pipe sections is dissolved in detergent, the mixing effect of detergent and water can be effectively improved, and the foaming effect of detergent can be enhanced. At the same time, by further setting a first flow passage 23 in the arc plate of the flow guiding structure, the fluid pressure and flow rate of the fluid flowing to the fluid outlet 112 can be increased. When the fluid at the fluid outlet 112 flows to the spray device 60, the spray flow rate and spray pressure of the spray device 60 can be increased. By further setting a baffle 3 at the connecting port 113, the backflow of fluid in the first pipe section 11 into the second pipe section 12 can be avoided due to excessive fluid pressure. When the second pipe section 12 is connected to the pump body through a pipeline, the impact force on the pump body can be reduced, ensuring the normal operation of the pump body and extending the service life of the pump body.

[0049] This embodiment also proposes a washing device, which can be a drum washing device or a pulsator washing device.

[0050] like Figures 6-10 As shown, the washing equipment includes a housing 20, a drum assembly, a spray device 60, a water system, and the aforementioned three-way connector 10. The drum assembly is housed within the housing 20 and includes an outer drum 30 and a rotatable inner drum 40 housed within the outer drum 30. The outer drum 30 serves as a water container, and the inner drum 40 serves as a washing drum. Preferably, the inner drum 40 and the outer drum 30 are coaxially arranged. The inner drum 40 has multiple water passages in its wall, through which water flows between the outer drum 30 and the inner drum 40.

[0051] The inner drum 40 includes an opening, and the housing 20 includes a door corresponding to the opening, which is used to open or close the opening. The user can insert the fabric to be washed into the inner drum 40 through the opening. A spray device 60 is located at the opening of the inner drum 40, and the spray direction of the spray device 60 is towards the inner drum 40. Preferably, the spray device 60 includes a spray head, which is located above the opening. The spray head sprays water from top to bottom, which can improve the cleaning effect on detergent, dirt, etc., on the fabric surface.

[0052] The water system includes a first inlet flow path 101 and a return flow path 103, which are independent of each other. The inlet end of the first inlet flow path 101 is connected to an external water supply pipeline, such as a municipal water supply pipeline. The outlet end of the first inlet flow path 101 is connected to a spray device 60. The inlet and outlet ends of the return flow path 103 are connected to the outer cylinder 30 and the spray device 60, respectively. The spray device 60 can spray the inner cylinder 40 with the water from the first inlet flow path 101 and / or the return water from the return flow path 103. Water from the external water supply pipeline can enter the inner cylinder 40 through the first inlet flow path 101 under the action of the spray device 60 in a spray-in manner. Water in the outer cylinder 30 can flow into the inner cylinder 40 through the return flow path 103, achieving circulating spraying under the action of the spray device 60. The water flow direction of the first inlet flow path 101 is referenced to... Figure 10 The direction of water flow in return water path 103 is indicated by the red arrow in the middle. Figure 10 The direction indicated by the green arrow in the middle.

[0053] The first fluid inlet 111 of the tee is connected to the outlet of the first water inlet path 101, the second fluid inlet 121 is connected to the outlet of the return water path 103, and the fluid outlet 112 is connected to the spray device 60 through the spray pipe 80. The return water pipeline is also equipped with a circulation pump 70. Under the action of the circulation pump 70, the water in the outer cylinder 30 flows through the return water path 103 to the second fluid inlet 121 of the tee connector 10.

[0054] In a specific example, the spray device 60 is located above the drum opening. The washing equipment also includes a crossbeam 211, a three-way connector 10 is located between the crossbeam 211 and the outer drum 30, and a limiting hole 212 is provided at the position corresponding to the limiting structure 4 of the connector on the crossbeam 211, and a fixing hole 213 is provided at the position corresponding to the fixing structure 5. The limiting structure 4 is in a limiting engagement with the limiting hole 212, and the fixing structure 5 is in a fixing engagement with the fixing hole 213.

[0055] The washing equipment also includes a second water inlet path 102 and a detergent dispenser 50. The inlet end of the second water inlet path 102 is connected to an external water supply pipe, and the outlet end of the second water inlet path 102 is connected to the outer drum 30. Water from the external water supply pipe can flow directly into the outer drum 30 through the second water inlet path 102. The detergent dispenser 50 is located in the second water inlet path 102, and the detergent in the detergent dispenser 50 can enter the outer drum 30 with the water flow in the second water inlet path 102. The first water inlet path 101 can be a separate water path or can share a water path with the second water inlet path 102.

[0056] In one example, the washing equipment further includes a main water inlet pipe, which is connected to the first water inlet flow path 101 and the second water inlet flow path 102. The outlet end of the main water inlet pipe is equipped with a water inlet device 90, and the first water inlet flow path 101 and the second water inlet flow path 102 are connected to the main water inlet pipe through the water inlet device 90. The water inlet device 90 includes a first water inlet control valve and a second water inlet control valve. The first water inlet control valve controls the flow between the main water inlet flow path and the first water inlet flow path 101, and the second water inlet control valve controls the flow between the main water inlet flow path and the second water inlet flow path 102.

[0057] In one example, the bottom of the outer cylinder 30 is also provided with a drain outlet, and the water system also includes a drain flow path 104. The inlet end of the drain flow path 104 is connected to the drain outlet, and the outlet end is located outside the washing device. The drain outlet is provided with a drain valve, or a drain pump is provided on the drain flow path 104. Preferably, the circulating water pump is a dual-purpose pump for drainage and circulation, used to pump water from the outer cylinder 30 into the return water flow path 103 during circulating spraying, or to pump water from the outer cylinder 30 into the drain flow path 104 during drainage. The water flow direction in the drain flow path 104 is referenced to... Figure 10 The direction indicated by the black arrow in the middle.

[0058] In this embodiment, by connecting the return water flow path 103 and the first water inlet flow path 101 to the spray device 60 through the T-connector 10, the function of simultaneous water intake and circulating spraying can be realized. After the circulating spraying is turned on, the mixture of detergent and water can be continuously drawn into the washing chamber and sprayed onto the clothes at the spray device 60. The clothes in the inner drum 40 are evenly sprayed with detergent mixture, and the stacked clothes can also be absorbed by the weight flow of the mixture. In this way, whether it is the surface clothes or the middle and lower layers of clothes, the detergent mixture can be penetrated in all directions. Then, the clothes are tumbled by the rotation of the inner drum 40 to achieve the effect of cleaning the clothes.

[0059] The return water flow path 103 and the first inlet water flow path 101 are opened simultaneously, enabling simultaneous circulating spraying and water intake. This also allows for secondary premixing of the detergent, increases spray pressure, expands the spray area, and enhances the spraying effect. Furthermore, the T-joint 10 further optimizes the mixing of detergent and water, generating abundant foam, thereby improving washing efficiency and shortening the overall washing cycle time. This increases washing efficiency, reduces energy consumption, and improves the user experience.
