Description

Technical Field

[0001] This utility model relates to the technical field of cleaning machines that can clean tableware and / or fruits and vegetables, and specifically to a water distribution valve and a cleaning machine that uses the water distribution valve. Background Technology

[0002] For countertop and cabinet dishwashers, due to their large washing space, they are generally designed with three spray arms: top, middle, and bottom, to achieve better washing results. During operation, the wash pump delivers water through pipes to the top, middle, and bottom spray arms. The water sprays out from these arms, rinsing the dishes before falling back into the water cup at the bottom of the dishwasher. The wash pump then delivers the fallen water back to the top, middle, and bottom spray arms, completing one cycle. Because there are many pipes leading to each spray arm, if all pipes are open, a large amount of water is required to maintain the system's circulation.

[0003] To save water, current dishwashers are generally designed with a water distribution valve. This valve controls the connection or disconnection of pipes leading to each spray arm, thereby controlling the spraying state of each spray arm as needed and conserving water. For example, the Chinese utility model patent application CN202222347049.7 (publication number CN218543266U) discloses a water distribution valve structure, which includes a water cup and a water distribution valve housing. The water cup has a housing mounting groove, and the water distribution valve housing is mounted on the housing mounting groove. The side wall of the water distribution valve housing has a water inlet and several side water outlets. The bottom surface of the housing mounting groove has several water passage holes. A connecting shaft is installed inside the water distribution valve housing, and a lever is mounted on the connecting shaft. The lever has an upper water outlet that matches the water passage holes. The lever is placed on the bottom surface of the housing mounting groove and is movably connected to it. The lever also has a stop arm that matches the side water outlets. The stop arm is placed on the side wall of the water distribution valve housing where the side water outlets are located and is movably connected to it.

[0004] In this patent, because the water inlet area cannot be adjusted, the water flow rate entering the water distribution valve also cannot be adjusted. This makes it impossible to adjust the flow rate according to usage needs, which will affect the cleaning effect or cause a waste of water resources. Utility Model Content

[0005] The first technical problem to be solved by this utility model is to provide a water distribution valve with a simplified structure and the ability to adjust the inlet water flow rate, in light of the current state of the prior art.

[0006] The second technical problem to be solved by this utility model is to provide a cleaning machine that uses the above-mentioned water distribution valve, in view of the current state of the prior art.

[0007] The technical solution adopted by this utility model to solve the first technical problem mentioned above is: a water distribution valve, comprising...

[0008] The valve body has a water inlet chamber, and the side wall of the valve body is provided with a water inlet and a first water outlet, both of which are connected to the water inlet chamber. The water inlet is used to connect with the drain outlet of the cleaning machine.

[0009] Its characteristic is that it also includes

[0010] The first baffle is located in the water inlet chamber and is set against the side wall of the water inlet chamber;

[0011] The driving mechanism is connected to the first baffle and is used to drive the first baffle to move along the side wall of the water inlet chamber, so that the first baffle can block or open the first water outlet. In this state, the first baffle will partially or completely open the water inlet.

[0012] In order for the drive mechanism to drive the first baffle to move along the side wall of the water inlet chamber, the drive mechanism includes a drive component and a drive shaft connected to the drive component. The drive shaft extends vertically and can rotate about its axis. A first connecting rod extending radially is provided on the peripheral wall of the drive shaft. A second connecting rod is inserted and fitted on the first connecting rod. The first baffle is located at the end of the second connecting rod.

[0013] To ensure the sealing effect of the first baffle, the water distribution valve also includes an elastic element acting on the first baffle or the second connecting rod, so that the first baffle tends to abut against the side wall of the water inlet chamber. This tight abutment between the first baffle and the side wall of the water inlet chamber prevents leakage when the first outlet or inlet is closed; simultaneously, the elastic element design ensures elastic contact between the first baffle and the water inlet chamber, preventing the first baffle from becoming stuck.

[0014] To further increase the water distribution of the water distribution valve, the top of the valve body is also provided with a second water outlet that communicates with the water inlet chamber, and the top of the drive shaft is provided with a second baffle that is fixed to it in the circumferential direction. The second baffle can open or close the second water outlet.

[0015] To ensure the sealing effect of the second baffle on the second outlet, the bottom of the second baffle is provided with a plug rod that is inserted into the drive shaft. The plug rod can move up and down relative to the drive shaft, but it is always constrained to the drive shaft. The plug rod will move upward under water pressure, so that the second baffle is tightly pressed against the top wall of the valve body, ensuring the sealing effect when the second outlet is closed.

[0016] To facilitate the first baffle to partially or completely open the water inlet, the water inlet includes a first water inlet and a second water inlet spaced apart circumferentially along the water inlet cavity. Either the first water inlet or the second water inlet can be selectively blocked by the first baffle, or both the first water inlet and the second water inlet can be offset from the first baffle.

[0017] Since the first water inlet and the second water inlet are arranged at intervals, in order to facilitate the water flow to enter the first water inlet or the second water inlet, an opening separated from the water inlet chamber is further provided on the side wall of the valve body. This opening is adjacent to the first water inlet, and the opening and the second water inlet are connected through a flow channel. An inlet corresponding to both the opening and the first water inlet is further provided on the side wall of the valve body.

[0018] In order to reduce the pressure loss during the water flow, the flow channel spirally extends along the circumferential direction of the water inlet chamber, and the flow channel has an arc-shaped structure with a gradually increasing cross-sectional area along the water flow direction. This design of the flow channel makes the water flow smoothly with a small pressure loss.

[0019] Because the installation space of the dishwasher is limited, if the height of the water distribution valve is relatively high, the height of the washing chamber of the dishwasher needs to be compressed, so that the number of dishes that can be placed in the washing chamber is less; if the space of the washing chamber of the dishwasher is not compressed, the overall height of the dishwasher is relatively high, which is not convenient for installing the drain pipe, etc. In order to reduce the height of the water distribution valve, the driving member is a motor. The motor includes a main body and an output shaft. The output shaft extends vertically and is fixed to the driving shaft. For this motor, when the output shaft extends vertically, the height of the main body is L1, and when the output shaft extends horizontally, the height of the main body is L2, and L1 < L2. This is equivalent to the motor lying horizontally with a lower height.

[0020] The technical solution adopted by the present utility model to solve the above second technical problem is as follows: A cleaning machine, characterized in that it includes a box body and a water cup located at the bottom of the box body. The bottom wall of the water cup has a sunken bottom cavity, the drain port is opened on the bottom cavity, and the above-mentioned water distribution valve is provided on the outer bottom wall of the water cup.

[0021] Compared with the prior art, the advantages of the present utility model are as follows: The first baffle of the present utility model can partially cover or completely open the water inlet, so that the water inflow can be adjusted. When a large water inflow is required, the water inlet is completely opened. When a small water inflow is required, the water inlet is partially opened. The water inflow is adjusted by adjusting the water inlet area. In this way, while ensuring the cleaning effect, the water flow can be saved;

[0022] In addition, the first baffle of the present utility model can not only adjust the water inlet area of the water inlet, but also adjust the opening or closing of the first water outlet, which has multiple functions and a simple structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] In the description of this utility model patent, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an adhesive connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model patent based on the specific circumstances.

[0031] like Figures 1-5 As shown, the cleaning machine of this preferred embodiment includes a housing, a water cup, and a water distribution valve. The water cup is located at the bottom of the housing, and the bottom wall of the water cup has a recessed cavity. The drain outlet is opened on the cavity, and the water distribution valve is located on the outer bottom wall of the water cup. This is prior art and will not be described in detail here.

[0032] The water distribution valve includes a valve body 1, a first baffle 2, a second baffle 3, and a drive mechanism.

[0033] The valve body 1 has a water inlet chamber 11. The side wall of the valve body 1 is provided with a water inlet and a first water outlet 12, both connected to the water inlet chamber 11. The top of the valve body 1 is also provided with a second water outlet 13, connected to the water inlet chamber 11. The water inlet is used to connect with the drain outlet of the cleaning machine. In this embodiment, the valve body 1 is formed by inserting an upper shell 1a and a lower shell 1b together to form the water inlet chamber 11. A sealing ring 1c is provided between the upper shell 1a and the lower shell 1b to prevent water leakage. The valve body 1 and the water cup are integrally formed. The first water outlet 12 is connected to a spray arm, and the second water outlet 13 is connected to a spray arm.

[0034] like Figure 2 As shown, the first baffle 2 and the second baffle 3 are both driven and connected to the driving mechanism. The driving mechanism includes a driving component 4 and a driving shaft 5 driven and connected to the driving component 4. The driving shaft 5 extends vertically and can rotate around its axis.

[0035] The first baffle 2 is disposed in the water inlet cavity 11 and is attached to the side wall of the water inlet cavity 11. The drive shaft 5 has a first connecting rod 51 extending radially on its peripheral wall. A second connecting rod 52 is inserted and fitted on the first connecting rod 51. The first baffle 2 is disposed at the end of the second connecting rod 52, so that the first baffle 2 moves circumferentially along the side wall of the water inlet cavity 11 under the drive of the drive mechanism, thereby realizing that the first baffle 2 blocks or opens the first water outlet 12. In this state, the first baffle 2 partially or completely opens the water inlet.

[0036] The water distribution valve also includes an elastic element 53 acting on the first baffle 2 or the second connecting rod 52, so that the first baffle 2 tends to abut against the side wall of the water inlet chamber 11. In this way, the first baffle 2 abuts tightly against the side wall of the water inlet chamber 11, which can prevent water leakage when the first outlet 12 or the water inlet is closed; at the same time, the design of the elastic element 53 makes elastic contact between the first baffle 2 and the water inlet chamber 11, so that the first baffle 2 will not be stuck.

[0037] The top of the drive shaft 5 is provided with a second baffle 3 that is fixed to it in the circumferential direction. The second baffle 3 can open or close the second outlet 13. The bottom of the second baffle 3 is provided with a plug rod 31 that is inserted into the drive shaft 5. The plug rod 31 can move up and down relative to the drive shaft 5, but the plug rod 31 is always constrained on the drive shaft 5. The plug rod 31 will move upward under the action of water pressure, so that the second baffle 3 is tightly pressed against the top wall of the valve body 1, ensuring the sealing effect when the second outlet 13 is closed. Alternatively, the drive shaft 5 is provided with a slot 50 for the plug rod 31 to move. When the second baffle 3 is pressed against the top wall of the water inlet chamber, the plug rod 31 is still inserted in the slot 50.

[0038] The water inlet includes a first water inlet 14 and a second water inlet 15 arranged circumferentially along the water inlet cavity 11. Either the first water inlet 14 or the second water inlet 15 can be selectively blocked by the first baffle 2, or both the first water inlet 14 and the second water inlet 15 can be staggered from the first baffle 2 to partially or completely open the water inlet.

[0039] Because the first inlet 14 and the second inlet 15 are spaced apart, in order to facilitate the water flow into the first inlet 14 or the second inlet 15, the side wall of the valve body 1 is also provided with an opening 16 that is separated from the water inlet chamber 11. The opening 16 is adjacent to the first inlet 14. The opening 16 and the second inlet 15 are connected through a flow channel 10. The flow channel 10 extends spirally along the circumference of the water inlet chamber 11, and the flow channel 10 has an arc-shaped structure with a cross-sectional area that gradually increases along the direction of water flow. The design of the flow channel 10 makes the water flow smooth and the pressure loss small. The side wall of the valve body 1 is also provided with an inlet 17 that corresponds to both the opening 16 and the first inlet 14.

[0040] The areas of the first inlet 14 and the second inlet 15 may be the same or different.

[0041] The water distribution valve in this embodiment can have the following operating states:

[0042] 1. The second baffle 3 covers the second outlet 13, the first baffle 2 covers the second inlet 15, and the first outlet 12 and the first inlet 14 are in the open state.

[0043] 2. The first baffle 2 simultaneously covers the first inlet 14 and the first outlet 12, while the second inlet 15 and the second outlet 13 are both in the open state;

[0044] 3. The first inlet 14 is blocked by the first baffle 2, and the second inlet 15, the first outlet 12 and the second outlet 13 are all in the open state. At this time, water flows through both the top and bottom, but because the first inlet 14 is blocked, the flow rate can be reduced.

[0045] 4. The second inlet 15 is blocked by the first baffle 2. The first inlet 14, the first outlet 12 and the second outlet 13 are all in the open state. At this time, water flows through both the top and bottom. However, because the second inlet 15 is blocked, the flow rate can be reduced. Furthermore, when the areas of the first inlet 14 and the second inlet 15 are different, there are two levels of flow rate adjustment.

[0046] 5. The first water inlet 14, the second water inlet 15, the first water outlet 12, and the second water outlet 13 are all in the open state.

[0047] As can be seen, the first baffle 2 can partially cover or fully open the water inlet, thus adjusting the water flow. When a large water flow is required, the water inlet is fully opened, and when a small water flow is required, the water inlet is partially opened. By adjusting the water inlet area, the water flow can be adjusted, thus ensuring the cleaning effect while saving water flow.

[0048] In addition, the first baffle 2 can not only adjust the water inlet area, but also adjust the opening or closing of the first outlet 12, making it a multi-functional and structurally simple device.

[0049] Because dishwasher installation space is limited, if the water distribution valve is too high, the height of the dishwasher's washing chamber needs to be reduced, thus limiting the number of dishes that can be placed in the washing chamber. If the washing chamber space is not reduced, the overall height of the dishwasher will be too high, making it inconvenient to install drain pipes, etc. To reduce the height of the water distribution valve, the drive component 4 is a motor, which includes a main body 41 and an output shaft. The output shaft extends vertically and is fixed to the drive shaft 5. For this motor, the height of the main body 41 is L1 when the output shaft extends vertically and L2 when the output shaft extends horizontally.
