[0001] This invention belongs to the field of washing equipment, specifically, it relates to a detergent switching and dispensing device and washing equipment. Background Technology

[0002] Currently, people's functional requirements for washing machines are becoming increasingly sophisticated. Among them, the automatic detergent dispensing function eliminates the need for users to manually add detergent, saving users time and effort. Therefore, the demand for automatic detergent dispensing functions is growing.

[0027] Furthermore, there is a gap between the inner sidewalls of the two ends of the valve core that are opposite to the valve body, and the first liquid inlet channel and the second liquid inlet channel are respectively connected to the gap.

[0028] Furthermore, the first liquid inlet channel and the second liquid inlet channel are respectively provided through both sides of the support base and communicate with the gap;

[0047] like Figures 1 to 4 As shown, the detergent dispensing device of the present invention includes a switching valve. The switching valve has an inlet 11 and multiple outlets 12 on its side, the inlet 11 and the multiple outlets 12 being spaced apart along the circumference of the switching valve. The switching valve controls the connection and disconnection between the inlet 11 and the multiple outlets 12.

[0048] This invention features an inlet 11 and multiple outlets 12 on the side of a switching valve. By controlling the connection and disconnection between the inlet 11 and the multiple outlets 12 through the switching valve, detergent can be dispensed into multiple washing machines through the multiple outlets 12 of the switching valve. Multiple washing machines can share a single detergent dispensing device, eliminating the need for multiple detergent dispensing devices. This achieves multi-purpose functionality with a single valve, resulting in a simple structure, small footprint, and reduced costs. Furthermore, the inlet 11 and multiple outlets 12 are spaced apart along the circumferential direction on the side of the switching valve, ensuring a smoother dispensing path without bends or dead angles, and reducing detergent residue inside the switching valve.

[0049] In this invention, the liquid inlet 11 and the plurality of liquid outlets 12 are respectively connected, or two or more of the liquid inlet 11 and the plurality of liquid outlets 12 can be connected simultaneously.

[0050] Furthermore, the switching valve includes a valve body 1 and a valve core 2.

[0051] The inlet 11 and multiple outlets 12 are spaced apart along the circumferential direction on the side of the valve body 1. The valve core 2 is rotatably disposed in the valve body 1 along the circumferential direction. The outer circumferential wall of the valve core 2 is rotatably sealed to at least a portion of the inner circumferential wall of the side of the valve body 1, for sealing the multiple outlets 12.

[0052] The outer peripheral wall of the valve core 2 is provided with a through outlet 232, which can be selectively connected to or disconnected from a liquid outlet 12 when the valve core 2 rotates.

[0053] In this invention, an outlet 232 is provided on the outer peripheral wall of the valve core 2. By controlling the rotation of the valve core 2, the outlet 232 of the valve core 2 is connected to one of the liquid outlets 12, allowing water or detergent to enter. The outlet 232 of the valve core 2 is connected to multiple liquid outlets 12 respectively, allowing detergent to be added to multiple washing machines. The structure is simple and the operation and control are simple.

[0054] Furthermore, the outer peripheral plate 23 is also provided with an inlet 231, which is connected to the outlet 232. When the outlet 232 is connected to any liquid outlet 12, the inlet 231 is connected to the liquid inlet 11.

[0055] When the outlet 232 of the valve core 2 is connected to the liquid outlet 12 and the inlet 231 is connected to the liquid inlet 11, the liquid inlet 11 is connected to the liquid outlet 12, and detergent can be dispensed into the designated washing machine through the switching valve. When the outlet 232 of the valve core 2 is disconnected from the liquid outlet 12, detergent dispensing stops.

[0056] The outer peripheral wall of the valve core 2 can be rotatably and sealingly connected to a portion of the inner peripheral wall of the valve body 1, or it can be rotatably and sealingly connected to all the inner peripheral walls of the valve body 1. During rotation, it can at least close or open the plurality of liquid outlets 12.

[0057] The switching valve also includes a rotating shaft 3. The rotating shaft 3 is rotatably and sealingly inserted into one end of the valve body 1. The rotating shaft 3 is connected to the valve core 2 and is used to drive the valve core 2 to rotate within the valve body 1.

[0058] Furthermore, the detergent switching and dispensing device also includes a motor 4, which is driven by the rotating shaft 3 to drive the rotating shaft 3 to rotate the valve core 2. The motor 4 is connected to the switching valve via a connector.

[0059] Preferably, the motor 4 is a stepper motor 4, which can control the rotating shaft 3 to rotate within a preset angle range.

[0060] The valve body 1 has a mounting hole at one end. The rotating shaft 3 can be directly and sealingly connected to the mounting hole of the valve body 1 via a sealing ring. Alternatively, the rotating shaft 3 can be assembled and connected to other structures on the valve core 2, and these other structures can be directly and sealingly connected to the mounting hole of the valve body 1 via sealing rings, for example, the rotating shaft 3 can be inserted into other structures.

[0061] like Figures 2 to 4 As shown, the valve body 1 has a liquid inlet channel connecting the liquid inlet 11 and the liquid outlet 232. Preferably, when the liquid outlet 232 is rotated to connect with any of the liquid outlets 12, it connects with the liquid inlet 11 of the valve body 1.

[0062] Furthermore, the valve core 2 includes a shaft seat 21, a support seat 22, and an outer peripheral plate 23.

[0063] One axial end of the bearing seat 21 is connected to the rotating shaft 3. The support seat 22 extends radially outward from the outer peripheral wall of the bearing seat 21. The inner peripheral wall of the outer peripheral plate 23 is connected to the outer peripheral wall of the support seat 22, and the outer peripheral wall of the outer peripheral plate 23 is in contact and sealed with the inner peripheral wall of the valve body 1. The outlet 232 is disposed through the outer peripheral plate 23.

[0064] By setting an outer peripheral plate 23, the present invention can achieve contact and sealing between the outer peripheral plate 23 and the inner peripheral wall of the valve body 1, blocking multiple liquid outlets 12. At the same time, when the outlet 232 on the outer peripheral plate 23 is rotated to be opposite to the liquid outlet 12, the liquid inlet 11 is connected to the liquid inlet channel, so as to realize liquid inlet of the valve body 1.

[0065] Preferably, the outer peripheral plate 23 is a circular outer peripheral plate 23 or an outer peripheral plate 23 extending in an arc shape. The inlet 231 is an arc-shaped notch provided on the outer peripheral plate 23 of the valve core 2.

[0066] When the outlet 232 is connected to a selected liquid outlet 12, the inlet 231 is connected to the liquid inlet 11. Liquid enters the inlet 231 of the valve core 2 through the liquid inlet 11, flows through the liquid inlet channel to the outlet 232, and is discharged from the selected liquid outlet 12 of the valve body 1.

[0067] The plurality of liquid outlets 12 are evenly spaced along the circumferential direction at the bottom end of the side of the valve body 1. The liquid inlet 11 is located at the top end of the side of the valve body 1. The plurality of liquid outlets 12 and liquid inlet 11 of the valve body 1 are provided with outwardly extending connectors.

[0068] Preferably, the two axial ends of the outer peripheral plate 23 are in contact with and sealed to the inner sidewalls of the two ends of the valve body 1, which can further improve the sealing performance of the valve body 1.

[0069] Furthermore, the liquid inlet channel includes a first liquid inlet channel 221 and a second liquid inlet channel 222.

[0070] The first liquid inlet channel 221 is disposed on the support base 22 and communicates with the inlet 231. The second liquid inlet channel 222 is disposed on the support base 22 and communicates with the outlet 232. The first liquid inlet channel 221 and the second liquid inlet channel 222 are connected.

[0071] The first liquid inlet channel 221 extends between the inlet 231 and the bearing 21. The second liquid inlet channel 222 extends between the outlet 232 and the bearing 21.

[0072] In one embodiment, there is a gap between the inner sidewalls of the two ends of the valve core 2 that are opposite to the valve body 1, and the first liquid inlet channel 221 and the second liquid inlet channel 222 are respectively connected to the gap, so that liquid can quickly enter the second liquid inlet channel 222 from the first liquid inlet channel 221.

[0073] Preferably, the first liquid inlet channel 221 and the second liquid inlet channel 222 are respectively arranged through both sides of the support base 22 and communicate with the gap.

[0074] One specific implementation plan is, for example: Figure 3 As shown, the support base 22 consists of multiple support arms spaced apart on the outer peripheral wall of the shaft seat 21 along the outer peripheral direction. The inlet 231 and outlet 232 are respectively located on the outer peripheral plate 23 between two adjacent support arms. A first liquid inlet channel 221 and a second liquid inlet channel 222 are respectively formed between the two adjacent support arms, which are respectively connected to the gap.

[0075] The inlet 231 and the outlet 232 are located at both ends of the outer peripheral plate 23 in the radial direction.

[0076] One end of the support arm is connected to the outer peripheral wall or the bearing 21 with a rounded transition to prevent detergent residue.

[0077] Another specific implementation is that the support seat 22 is a boss (not shown in the figure) extending along the outer periphery and disposed on the outer peripheral wall of the bearing seat 21. The first liquid inlet channel 221 and the second liquid inlet channel 222 are respectively disposed through both sides of the boss and communicate with the gap.

[0078] The first liquid inlet channel 221 and the second liquid inlet channel 222 extend outward at an angle from the axis of the bearing 21 to form a fan shape.

[0079] Another implementation scheme is, as Figure 4 As shown, the bearing seat 21 is provided with through holes 211 extending through both sides of the peripheral wall of the bearing seat 21. The first liquid inlet channel 221 and the second liquid inlet channel 222 are respectively connected to the through holes 211.

[0080] Liquid enters the second inlet channel 222 through the inlet 11 and the first inlet channel 221, then through the perforation 211, and finally exits through the selected outlet 12. Alternatively, liquid enters the second inlet channel 222 through the inlet 11 and the first inlet channel 221, then through the perforation 211 and the gap between the valve core 2 and the valve body 1, and finally exits through the selected outlet 12.

[0081] The other end of the bearing seat 21 is either close to or spaced from the inner wall of the other end of the valve body 1.

[0082] Specifically, the support 22 is a boss extending along the outer periphery of the bearing 21. The first liquid inlet channel 221 and the second liquid inlet channel 222 extend into the interior of the boss.

[0083] The first liquid inlet channel 221 and the second liquid inlet channel 222 extend outward from the axis of the bearing 21 at an angle to form a fan shape. The boss is an annular boss or a boss that extends in an arc shape.

[0084] Furthermore, the outer peripheral wall of the bearing seat 21 is provided with an annular protrusion, which decreases from the connection between the bearing seat 21 and the support seat 22 towards both ends in the axial direction of the bearing seat 21, so as to facilitate the smooth drainage of liquid passing through the bearing seat 21 and prevent liquid from remaining on the valve core 2.

[0085] Furthermore, a limiting block 13 is provided on the inner wall of the end of the valve body 1, which abuts against the inner wall of the first liquid inlet channel 221 to limit the rotation of the valve core 2 within a predetermined angle, so that when the outlet 232 is selectively connected to the liquid outlet 12, the inlet 231 is connected to the liquid inlet 11. Preferably, the limiting block 13 is disposed opposite to the liquid inlet 11.

[0086] Preferably, the limiting block 13 is located between the shaft seat 21 and the liquid outlet 12. When one inner sidewall of the first liquid inlet channel 221 abuts against one side of the limiting block 13, the outlet 232 communicates with the leftmost liquid outlet 12 among the plurality of liquid outlets 12; when the other inner sidewall of the first liquid inlet channel 221 abuts against the other side of the limiting block 13, the outlet 232 communicates with the rightmost liquid outlet 12 among the plurality of liquid outlets 12.

[0087] Preferably, the valve body 1 is a cylindrical shell, and the liquid inlet 11 and a plurality of liquid outlets 12 are arranged at intervals along the circumferential direction on the outer peripheral wall of the valve body 1.

[0089] Furthermore, the detergent switching and dispensing device also includes a detergent dispenser and a circulation pump. The detergent dispenser is connected to the inlet 11 of the switching valve.

[0090] The circulation pump is connected between the detergent dispenser and the inlet 11 of the switching valve. Alternatively, the circulation pump is installed on the outlet pipeline connected to the multiple outlets 12 of the switching valve.

[0091] The present invention also provides a washing device having any of the detergent switching and dispensing devices described above, the washing device further comprising multiple washing machines, a circulation pump, and a detergent dispenser. The multiple washing machines are respectively connected to multiple liquid outlets 12 of the switching valve in a one-to-one correspondence.

[0092] The circulation pump is respectively installed between the liquid outlet 12 of the washing machine and the switching valve, and is used to draw liquid from the switching valve and supply it to the washing tub of the washing machine. Alternatively, the circulation pump is connected between the detergent dispenser and the liquid inlet 11 of the switching valve, and is used to draw liquid from the detergent dispenser into the switching valve.

[0093] Furthermore, in one embodiment, the washing equipment further includes multiple water inlet pipes. These pipes are connected between the washing machine and the outlet 12 of the switching valve, or the multiple water inlet pipes are each directly connected to the washing tub of the washing machine. Preferably, the water inlet pipes are connected between the circulation pump and the washing machine.
