[0036] Because the performance of the circulating pump in current washing equipment with circulating spray function is limited, when washing fabrics with circulating spray, there are problems such as insufficient premixing of detergent and water and insufficient foam, which affects washing efficiency and washing effect.

[0037] To address the above problems, this embodiment proposes a tee connector. The tee connector includes a connector body, which has a first fluid inlet, a second fluid inlet, and a fluid outlet. The connector body includes: The first pipe section has an inlet and an outlet forming a first fluid inlet and a fluid outlet, respectively. The pipe wall of the first pipe section has a first connecting port and a second connecting port, located on opposite sides of the first pipe section. The second pipe section has a second fluid inlet at its inlet and an outlet that is connected to the first pipe section via a first connecting port. The second pipe section also has a third connecting port on its wall. The third pipe section has its inlet connected to the second connecting port and its outlet connected to the third connecting port. Part of the fluid entering the first pipe section can enter the second pipe section through the third pipe section and mix with the fluid in the second pipe section before flowing out of the first pipe section.

[0038] This embodiment of the three-way connector, by setting up a first pipe section, a second pipe section, and a third pipe section, allows for simultaneous spraying and water intake in a washing equipment application scenario. This is achieved by connecting the first fluid inlet in the first pipe section to the municipal water supply pipeline, the second fluid inlet in the second pipe section to the circulation pipeline, and the fluid outlet in the first pipe section to the spray device. This optimizes the mixing of detergent and water, generating abundant foam, thereby effectively improving washing efficiency and shortening the overall washing cycle time. Furthermore, the third pipe section allows for the initial mixing of circulating water and tap water at the junction of the third and second pipe sections, and a second mixing at the junction of the second and first pipe sections, further enhancing the bubble effect and improving the washing performance.

[0039] The technical solution of this embodiment will be described in detail below with reference to the accompanying drawings. In the absence of conflict, the following implementation methods and examples can be combined with each other.

[0040] This embodiment proposes a tee connector 10, such as... Figures 1-7 As shown, the tee connector 10 includes a connector body 1, which has 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, a second pipe section 12, and a third pipe section, wherein: The inlet and outlet of the first pipe segment 11 form a first fluid inlet 111 and a fluid outlet 112, respectively. Preferably, the first fluid inlet 111 and the fluid outlet 112 are located at both ends along the length of the first pipe segment 11, allowing the first fluid to enter the first pipe segment 11 through the first fluid inlet 111 and exit through the fluid outlet 112. The structure of the first pipe segment 11 is not specifically limited; it can be a straight pipe segment, a bent pipe segment, or a combination of a straight and a bent pipe segment. The first pipe segment 11 can also be an independent pipe body or formed by splicing multiple pipe segments; no specific limitations are imposed here.

[0041] The first pipe section 11 has a first connecting port 113 and a second connecting port 114 on its pipe wall. The first connecting port 113 and the second connecting port 114 are located on opposite sides of the first pipe section 11. The first fluid in the first pipe section 11 can flow out through the first connecting port 113, and the external fluid can flow in through the second connecting port 114.

[0042] The inlet of the second pipe section 12 forms a second fluid inlet 121, and the outlet of the second pipe section 12 is connected to the first pipe section 11 through a first connecting port 113, so that the second fluid entering the second pipe section 12 can enter the first pipe section 11 through the first connecting port 113 and mix with the first fluid in the first pipe section 11. Preferably, the inlet and outlet of the second pipe section 12 are located at both ends of the length of the second pipe section 12. The second pipe section 12 can be a straight pipe section, a bent pipe section, or a combination of a straight pipe section and a bent pipe section. The second pipe section 12 can also be an independent pipe body, or it can be formed by splicing multiple pipe bodies, and no specific limitation is made here. The pipe wall of the second pipe section 12 has a third connecting port 122, so that external fluid can enter the second pipe section 12 through the third connecting port 122.

[0043] The inlet of the third pipe section is connected to the second connecting port 114, and the outlet of the third pipe section is connected to the third connecting port 122. Thus, the first fluid entering the first pipe section 11 is divided into two paths: one path flows directly along the first pipe section 11 to the fluid outlet 112, and the other path enters the third pipe section, where it mixes with the second fluid in the second pipe section 12. The mixed fluid in the second pipe section 12 flows to the first connecting port 113 and then re-enters the first pipe section 11, where it continues to mix with the first fluid, finally exiting from the fluid outlet 112. The fluid flow direction within the tee joint 10 is referenced... Figure 4 As indicated by the red arrow in the middle.

[0044] The third pipe segment can be a single bend, a combination of multiple straight pipe segments, or a combination of straight and bend pipe segments. The third pipe segment can be a single independent pipe or a combination of multiple pipe segments joined together; no specific limitation is made here.

[0045] As can be seen, this embodiment sets up a third pipe section, which realizes the two-time mixing of the second fluid and the first fluid in the second pipe section 12. The first time is when the first fluid flows into the second pipe section 12 through the third pipe section and mixes with the second fluid in the second pipe section 12. The second time is when the mixture of the first fluid and the second fluid enters the first pipe section 11 and mixes with the first fluid in the first pipe section 11 again. In the application scenario of washing equipment, when the first fluid is tap water and the second fluid is a detergent mixture, the detergent and tap water can be mixed twice, which effectively improves the foaming effect of washing and the cleaning effect on clothes.

[0046] It should be noted that the types of the first and second fluids in this embodiment are not specifically limited and can be flexibly adjusted according to the application scenario of the tee connector. That is, the first and second fluids can be the same type of fluid or different types of fluids.

[0047] In the application scenario of the washing equipment, the first fluid inlet 111 of the first pipe section 11 is connected to the municipal water supply pipeline, the second fluid inlet 121 of the second pipe section 12 is connected to the circulation pipeline, and the fluid outlet 112 of the first pipe section 11 is connected to the spray device 60. When the washing equipment is in the washing stage, the first fluid is tap water, and the second fluid is detergent mixture, which can realize simultaneous spraying and water intake, optimize the mixing of detergent and water, generate rich foam, thereby effectively improving washing efficiency and shortening the time of the entire washing cycle.

[0048] In this embodiment, the first, second, and third pipe bodies can be independent of each other and sealed together using methods such as snap-fitting, plug-in fitting, connector connection, bonding, or welding. Alternatively, as... Figure 2 As shown, the connector body 1 includes an upper cover 105 and a lower cover 106. The upper cover 105 and the lower cover 106 are fastened together to form a first pipe segment 11, a second pipe segment 12, and a third pipe segment. That is, both the upper cover 105 and the lower cover 106 have a portion of the structure of the first pipe segment 11, the second pipe segment 12, and the third pipe segment. When the upper cover 105 and the lower cover 106 are fastened together, the complete first pipe segment 11, the second pipe segment 12, and the third pipe segment are formed.

[0049] In one alternative implementation, such as Figure 4 and Figure 7 As shown, in the direction of water flow in the second pipe section 12, the third connecting port 122 is located upstream of the first connecting port 113, so as to ensure that the first fluid flowing out of the third pipe section is fully mixed with the second fluid in the second pipe section 12 before entering the first pipe section 11 through the first connecting port 113, thus ensuring a full mixing effect between the first fluid and the second fluid.

[0050] In one alternative implementation, such as Figure 4 and Figure 7 As shown, in the direction of water flow in the first pipe section 11, the second connecting port 114 is located upstream of the first connecting port 113, so as to prevent the mixed fluid flowing into the first pipe section 11 from the second pipe section 12 from flowing into the second pipe section 12 again through the third pipe section, thereby reducing the mixing effect of the first fluid and the second fluid.

[0051] In one alternative implementation, such as Figure 4 and Figure 7 As shown, the flow area of ​​the first connecting port 113 is larger than that of the second connecting port 114, so as to improve the efficiency of the mixed fluid in the second pipe section 12 entering the first pipe section 11 through the first connecting port 113, while avoiding excessive first fluid in the first pipe section 11 entering the third pipe section, and ensuring the fluid flow rate of the fluid outlet 112.

[0052] In one alternative implementation, such as Figure 4 and Figure 7As shown, the flow area of ​​the first connecting port 113 is larger than that of the third connecting port 122, so as to improve the efficiency of the mixed fluid in the second pipe section 12 entering the first pipe section 11 through the first connecting port 113. At the same time, the flow rate of the first fluid in the third pipe section entering the second pipe section 12 is controlled to ensure the proportion of the second fluid in the mixed fluid in the second pipe body. In the application scenario of washing equipment, the concentration of detergent entering the second pipe body can be guaranteed to ensure the washing effect.

[0053] In one alternative implementation, such as Figures 1-3 , Figure 7 As shown, the third pipe section includes an arc-shaped pipe section, and the second pipe section 12 is connected to the arc-shaped pipe section through a third connecting port 122 in a direction tangential or approximately tangential to it. That is, the location of the third connecting port is the tangent point between the second pipe section 12 and the arc-shaped pipe section. In this embodiment, by connecting the second pipe section 12 tangentially or approximately tangentially to the arc-shaped pipe section, it ensures that when the first fluid flowing out of the third pipe section merges into the second pipe section 12, it does not affect the flow direction of the first fluid within the second pipe section 12, thus avoiding turbulence at the point where the first and second fluids meet and ensuring smooth fluid flow within the second pipe section.

[0054] In addition, in the application scenario of washing equipment, since the second fluid inlet 121 of the second pipe body is connected to the circulation pump 70 through the circulation flow path 130, the second pipe section 12 is connected in a way that is tangential or approximately tangential to the arc-shaped pipe section, which can effectively reduce the impact of water pressure on the circulation flow path 130, prevent tap water from flowing back into the circulation flow path 130, and extend the life of the circulation pump 70.

[0055] In one alternative implementation, such as Figure 1 , Figures 3-5 As shown, the first pipe section 11 includes a first pipe section 101, a second pipe section 102, and a third pipe section 103. The second pipe section 102 connects the first pipe section 101 and the second pipe section 102. A first fluid inlet 111 is formed at the end of the first pipe section 101 away from the second pipe section 102. A fluid outlet 112 is formed at the end of the third pipe section 103 away from the second pipe section 102. A first connecting port 113 and a second connecting port 114 are formed in the third pipe section 103. The second pipe section 102 forms an angle with the first pipe section 101. The second pipe section 102 and the third pipe section 103 are arranged at an angle, and the first pipe section 101 and the third pipe section 103 extend in opposite directions. A clearance space 104 is formed between the first pipe section 101 and the second pipe section 102. At least part of the structure of the third pipe section is located in the clearance space 104, and the third pipe section 103, the second pipe section 12 and the third pipe section are located on the same horizontal plane. This can effectively reduce the space occupied by the third pipe section, reduce the volume of the entire tee joint 10, and adapt to more installation environments.

[0056] In one alternative implementation, such as Figures 1-7 As shown, the second pipe section 12 is inclined towards the first fluid inlet 111, and the third connecting port 122 is opened on the side of the third pipe section near the first fluid inlet 111. Preferably, as shown... Figure 3 As shown, the angle between the second pipe section 12 and the first pipe section 11 is A, and the range of A is 30°-60°, so as to avoid excessive water flow resistance when the first fluid and the second fluid meet at the first connecting port 113 due to the excessive angle.

[0057] In one alternative implementation, such as Figures 1-7 As shown, the tee connector 10 also includes a limiting member 4, which is disposed on the first pipe section 11. The limiting member 4 includes a limiting rib 41 and / or a limiting screw post 42. The limiting structure can improve the assembly reliability between the tee connector 10 and the equipment on which it is installed.

[0058] This embodiment also proposes a washing device, which can be a drum washing device or a pulsator washing device.

[0059] like Figures 8-12 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 on its wall, through which water flows between the outer drum 30 and the inner drum 40.

[0060] 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.

[0061] The water system includes a first inlet flow path 110 and a circulation flow path 130, which are independent of each other. The inlet end of the first inlet flow path 110 is connected to an external water supply pipeline, such as a municipal water supply pipeline. The outlet end of the first inlet flow path 110 is connected to a spray device 60. The inlet and outlet ends of the circulation flow path 130 are connected to the outer cylinder 30 and the spray device 60, respectively. The spray device 60 can spray the inner cylinder 40 using the water inlet from the first inlet flow path 110 and / or the return water from the circulation flow path 130. Water from the external water supply pipeline can enter the inner cylinder 40 through the first inlet flow path 110 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 circulation flow path 130, achieving circulating spraying under the action of the spray device 60. The water flow direction of the first inlet flow path 110 is referenced to... Figure 12 The direction of water flow in circulation path 130 is indicated by the red arrow in the middle. Figure 12 The direction indicated by the green arrow in the middle.

[0062] The first fluid inlet 111 of the tee is connected to the outlet of the first water inlet flow path 110, the second fluid inlet 121 is connected to the outlet of the circulation flow path 130, and the fluid outlet 112 is connected to the spray device 60 through the spray pipe 80. The circulation flow path 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 circulation flow path 130 to the second fluid inlet 121 of the tee connector 10.

[0063] 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 the crossbeam 211 has a limiting hole 212 at the position corresponding to the limiting rib of the connector, and a fixing hole 213 at the position corresponding to the screw post. The limiting rib and the limiting hole 212 are mutually limiting and engaged, and the screw post is fixedly engaged with the fixing hole 213 by screws.

[0064] The washing equipment also includes a second water inlet path 120 and a detergent dispenser 50. The inlet end of the second water inlet path 120 is connected to an external water supply pipe, and the outlet end of the second water inlet path 120 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 120. The detergent dispenser 50 is located in the second water inlet path 120, and the detergent in the detergent dispenser 50 can enter the outer drum 30 with the water flow in the second water inlet path 120. The first water inlet path 110 can be a separate water path or can share a water path with the second water inlet path 120.

[0065] In one example, the washing equipment further includes a main water inlet pipe, which is connected to a first water inlet flow path 110 and a second water inlet flow path 120. The outlet end of the main water inlet pipe is equipped with a water inlet device 90, and the first water inlet flow path 110 and the second water inlet flow path 120 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 110, and the second water inlet control valve controls the flow between the main water inlet flow path and the second water inlet flow path 120.

[0066] 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 140. The inlet end of the drain flow path 140 is connected to the drain outlet, and the outlet end is located outside the washing equipment. The drain outlet is equipped with a drain valve, or a drain pump is provided on the drain flow path 140. Preferably, the circulating water pump is a dual-purpose pump for both drainage and circulation, used to pump water from the outer cylinder 30 into the circulation flow path 130 during circulating spraying, or to pump water from the outer cylinder 30 into the drain flow path 140 during drainage. The water flow direction in the drain flow path 140 is referenced to... Figure 12 The direction indicated by the black arrow in the middle.

[0067] In this embodiment, by connecting the circulating flow path 130 and the first water inlet flow path 110 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.

[0068] The simultaneous activation of the circulation path 130 and the first water inlet path 110 enables simultaneous circulating spraying and water intake, and also provides secondary premixing of the detergent. This 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 results in increased washing efficiency, reduced energy consumption, and a better user experience.
