Description

Technical Field

[0001] This invention belongs to the field of dishwashing equipment, specifically, it relates to a water distribution device for a dishwasher and a dishwasher. Background Technology

[0002] In current technology, dishwashers, as an indispensable household appliance in modern kitchens, are favored by consumers for their efficient and convenient washing functions. To achieve thorough cleaning of dishes, dishwashers are typically designed with three independent water systems—lower, middle, and upper—corresponding to spray arms at different heights to ensure that water flow covers every corner of the dishwasher's interior. However, due to the limited output pressure of the washing pump, simultaneously supplying water to these three water systems often results in insufficient water pressure in each system, thus affecting the normal rotation of the spray arms and the washing effect.

[0003] To address this issue, traditional dishwashers typically employ a water distribution valve to control the switching of water flow between different water channels. Most existing water distribution valves utilize electrical components, switching the water outlet via an electronic control system or a power-driven mechanism. While this design meets the operational requirements of dishwashers to some extent, it also has significant drawbacks. First, the manufacturing cost of electrical water distribution valves is high, including electronic components, control circuits, and drive mechanisms, all of which increase the overall cost of the dishwasher. Second, the use of electrical components increases system complexity and introduces potential safety risks, such as circuit failures, short circuits, and electrical leakage, which may threaten user safety.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The technical problem to be solved by this invention is to overcome the shortcomings of the prior art. The purpose is to provide a water distribution device for a dishwasher, which adds an assembly mechanism. The baffle mechanism of the water distribution device is rotatably installed on the assembly mechanism. Each time water flows through, the baffle mechanism rotates to switch the water outlet connection. This provides a water circuit switching water distribution device that does not require power supply or electronic control. It realizes automatic water circuit switching through mechanical or physical principles, and solves the problems of high cost and low safety of existing electrical component water distribution devices.

[0006] Another object of the present invention is to provide a dishwasher.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is to provide a water distribution device for a dishwasher, comprising:

[0008] The container has an inlet and multiple circumferentially arranged outlets;

[0009] A baffle mechanism is movably located between the inlet and multiple outlets within the cavity, and is used to move under the drive of water flow.

[0010] An assembly mechanism is provided on the inner wall of the cavity. The baffle mechanism is rotatably mounted on the assembly mechanism and is used to rotate sequentially under the drive of water flow each time water is supplied, and to switch and connect with one of the multiple water outlets.

[0011] Furthermore, the assembly mechanism is provided with a guide part, and the baffle mechanism rotates in cooperation with the guide part to convert the reciprocating movement of the baffle mechanism between the inlet and the outlet into circumferential rotation, and to switch and connect with one of the multiple outlets.

[0012] Furthermore, the assembly mechanism protrudes from the inner wall of the cavity, and the assembly mechanism is provided with multiple guide parts at intervals, which are used to guide the baffle mechanism to rotate continuously in the same direction or alternately in the forward and reverse directions on the assembly mechanism during the reciprocating motion of the baffle mechanism, and then switch to connect with the next outlet.

[0013] Furthermore, the guide portion includes a first guide portion and a second guide portion, which are spaced apart on the assembly mechanism along the reciprocating movement direction; the first guide portion and the second guide portion are circumferentially staggered and have opposite guide surfaces;

[0014] The baffle mechanism is provided with a moving part. During the process of moving towards the outlet under the drive of water flow, the moving part moves along the positive guide surface of the second guide part, so that the baffle mechanism rotates in the positive direction around the assembly mechanism. After the water is stopped, when the baffle mechanism moves away from the outlet, the moving part moves along the negative guide surface of the first guide part, so that the baffle mechanism continues to rotate in the positive direction around the assembly mechanism.

[0015] Furthermore, the assembly mechanism extends protrudingly along the reciprocating movement direction of the baffle mechanism, and a plurality of second guide structures are spaced apart circumferentially at one end of the assembly mechanism near the outlet, and a plurality of first guide structures are spaced apart circumferentially at the other end of the assembly mechanism.

[0016] In the initial state, the moving part is assembled in the gap between two adjacent first guide structures; in the working state, the moving part is assembled in the gap between two adjacent second guide structures.

[0017] Furthermore,

[0018] The guide portion has guide surfaces that extend in the same direction from both ends of the guide surface along the reciprocating movement direction;

[0019] The guide surfaces of the first guide and the second guide are inclined in opposite directions.

[0020] The guide surfaces of the first guide and the second guide extend in opposite directions, and are used to move the corresponding guide moving part to the guide surface of the second guide or the guide surface of the first guide when the water inlet drive or the drive stops.

[0021] Furthermore, the baffle mechanism includes a rotating seat and a baffle, the baffle being sleeved on the outer periphery of one end of the rotating seat, the movable part protruding from the inner or outer peripheral wall of the rotating seat, and the rotating seat being sleeved on the outer periphery of the assembly mechanism or inserted into the inner peripheral wall of the assembly mechanism.

[0022] Furthermore, it includes an elastic mechanism that presses against the assembly mechanism and the rotating seat to provide a restoring force;

[0023] Preferably, the rotating seat has an internal mounting cavity, and one end of the rotating seat has an opening communicating with the mounting cavity; the protruding end of the assembly mechanism extends into one end of the rotating seat, and the elastic mechanism presses against the protruding end of the assembly mechanism and the other end inside the rotating seat.

[0024] Furthermore, the water distribution device includes a valve body and a valve cover. The water inlet is located on the outer peripheral wall at the bottom of the valve body for circumferential flow after water enters. Multiple water outlets are circumferentially spaced on the valve cover.

[0025] The baffle mechanism is provided with an outlet. After being guided by the guide part under the drive of water flow, the baffle mechanism covers the valve cover. The outlet is connected to a water outlet.

[0026] The present invention also provides a dishwasher having any of the water distribution devices described above.

[0027] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0028] (1) In this invention, when the dishwasher starts working, water flows into the cavity from the inlet and impacts the baffle mechanism. Due to the design features of the baffle mechanism, it rotates once under the initial impact force of the water flow, connecting with the preset outlet. As the water flow continues, the baffle mechanism remains in this position until it rotates again when the dishwasher starts supplying water next time. This discontinuous rotation method simplifies the control mechanism and reduces the complexity of the control system. It eliminates the need for complex electrical components and a continuous power source, reducing production costs. It also reduces the use of electrical components and mechanical wear, improving the overall performance and reliability of the dishwasher.

[0029] (2) This invention achieves water flow distribution by combining reciprocating movement and circumferential rotation, thus simplifying the structural design of the water distribution device.

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 electrical 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 invention based on the specific circumstances.

[0045] like Figures 1 to 8 As shown, this invention provides a water distribution device for a dishwasher. The main function of the water distribution device is to distribute the water flow from the water inlet 11 to multiple spray arms or cleaning areas inside the dishwasher. By precisely controlling the distribution of the water flow, it ensures that each area inside the dishwasher receives sufficient water for effective cleaning. This improves the cleaning effect of the dishwasher, helps remove dirt and residue from tableware, and ensures that the tableware meets hygiene standards.

[0046] The water distribution device includes a cavity 1, a baffle mechanism 2, and an assembly mechanism 3.

[0047] The cavity 1 has a water inlet 11 and multiple circumferentially arranged water outlets 12, which are used to distribute clean water to different positions or nozzles inside the dishwasher. The function of the cavity 1 is to provide a controlled space for water flow distribution.

[0048] The baffle mechanism 2 is movable between the inlet 11 and multiple outlets 12 located within the cavity 1, driven by the water flow. The function of the baffle mechanism 2 is to move between the inlet 11 and the outlets 12 according to the push of the water flow, thereby realizing the distribution and control of the water flow.

[0049] The assembly mechanism 3 is disposed on the inner wall of the cavity 1, and the baffle mechanism 2 is rotatably mounted on the assembly mechanism 3 for rotating sequentially under the water flow drive each time water is supplied, and switching to connect with one of the multiple water outlets 12.

[0050] The water distribution device's cavity 1 is made of a robust and durable material, such as stainless steel or reinforced plastic, to ensure it can withstand the high-pressure water flow and detergent corrosion inside the dishwasher. The number and location of the water outlets 12 are designed according to the specific needs of the dishwasher; preferably, there are three or more water outlets 12.

[0051] The baffle mechanism 2 is rotatably configured to match the inner wall of the cavity 1.

[0052] In this invention, when the dishwasher starts operating, water flows into the cavity 1 through the inlet 11 and impacts the baffle mechanism 2. Due to the design features of the baffle mechanism 2, it rotates once under the initial impact force of the water flow, connecting with the preset outlet 12. As the water flow continues, the baffle mechanism 2 remains in this position until it rotates again when the dishwasher starts supplying water. This discontinuous rotation method simplifies the control mechanism and reduces the complexity of the control system. It eliminates the need for complex electrical components and a continuous power source, reducing production costs. Furthermore, it reduces the use of electrical components and mechanical wear, improving the overall performance and reliability of the dishwasher.

[0053] In one embodiment, the baffle mechanism 2 is circumferentially rotatable relative to the assembly structure. After water enters, the baffle mechanism 2 rotates circumferentially, maintaining continuous communication with a water inlet 11. When the water distribution device stops the water intake, and water enters again, the baffle mechanism 2 continues to rotate, maintaining communication with the next water outlet 12.

[0054] Specifically, the assembly mechanism 3 includes a rotating seat mounted on the inner wall, and the baffle mechanism 2 is connected to the assembly mechanism 3 through the bearing of the rotating seat, allowing the baffle mechanism 2 to rotate around the rotating seat. Alternatively, the assembly mechanism 3 includes a fixed seat 41 protruding from the inner wall of the cavity 1, and the baffle mechanism 2 is rotatably mounted on the fixed seat 41. Multiple limiting parts and cooperating guide parts are provided on the inner wall of the cavity 1 that mates with the rotating seat or on the fixed seat 41.

[0055] When water enters, the water flow drives the baffle mechanism 2 to rotate and connects to a limiting part for circumferential limiting, thus connecting to an outlet 12. After water entry stops, under the action of gravity or elasticity, the baffle mechanism 2 rotates in the opposite direction to disengage from the limiting part. When water enters again, under the action of the guide part, it rotates to the next limiting part and connects to it for limiting, thus connecting to the next outlet 12, thereby realizing the switching of outlet 12.

[0056] Another implementation is that the assembly mechanism 3 is provided with a guide. The baffle mechanism 2 rotates in cooperation with the guide to convert the reciprocating movement of the baffle mechanism 2 between the inlet 11 and the outlet 12 into circumferential rotation, and can selectively connect with one of the multiple outlets 12.

[0057] The assembly mechanism 3 and the baffle mechanism 2 can be connected by a ratchet mechanism, a piston rod and wheel combination mechanism, or a crank slider mechanism combined with a gear transmission mechanism.

[0058] Preferably, the guide part can be designed as an arc or spiral shape that can guide the baffle mechanism 2 to rotate circumferentially, so that when the baffle mechanism 2 is impacted by water flow, it can rotate circumferentially along the trajectory of the guide part while reciprocating, thereby switching to connect with one of the multiple outlets 12.

[0059] The water distribution device of the present invention utilizes the dynamic characteristics of water flow and the ingenious design of the mechanical structure to achieve water flow distribution without the control of electrical components.

[0060] When the dishwasher starts operating, water flows into the cavity 1 through the inlet 11 and impacts the baffle mechanism 2, pushing it towards the outlet 12. As the baffle mechanism 2 moves towards the outlet 12, it engages with the guide portion on the assembly mechanism 3 and begins to rotate circumferentially. With this rotation, the baffle mechanism 2 gradually aligns with and connects to a specific outlet 12, guiding the water flow to that outlet 12.

[0061] When it is necessary to switch water outlet 12, the dishwasher stops supplying water, and the baffle mechanism 2 moves back to its initial position under the force of the reset mechanism (such as gravity or elasticity). Subsequently, when water is supplied again, the baffle mechanism 2 rotates circumferentially along the guide section in the same or opposite direction to align with and connect with the next water outlet 12.

[0062] If it rotates in the opposite circumferential direction, the rotation angle is different and the rotation angle is calculated so that after the rotation is completed, it is connected to the next outlet 12.

[0063] This invention achieves water flow distribution by combining reciprocating movement and circumferential rotation, thus simplifying the structural design of the water distribution device.

[0064] Furthermore, the assembly mechanism 3 protrudes from the inner wall of the cavity 1 and is used to install and guide the movement of the baffle mechanism 2. The assembly mechanism 3 is provided with multiple guide parts at intervals along its length. The guide parts are provided with components of a specific shape or tilt angle, which are used to guide the baffle mechanism 2 to rotate continuously in the same direction or alternately in the forward and reverse directions on the assembly mechanism 3 during the reciprocating motion, and then switch to communicate with the next outlet 12.

[0065] These guide parts, through different tilt angles or shape designs, cause the baffle mechanism 2 to be subjected to lateral forces during contact, thereby causing it to rotate. By precisely controlling the position and shape of the guide parts, the baffle mechanism 2 can be made to rotate continuously or alternately during reciprocating movement, thereby switching to different outlets 12.

[0066] Furthermore, the guide portion includes a first guide portion 311 and a second guide portion 321, which are spaced apart on the assembly mechanism 3 along the reciprocating movement direction. The first guide portion 311 and the second guide portion 321 are circumferentially staggered and have opposite guide surfaces.

[0067] The baffle mechanism 2 is provided with a moving part 21. During the process of moving towards the outlet 12 under the drive of water flow, the moving part 21 moves along the positive guide surface of the second guide part 321, so that the baffle mechanism 2 rotates in the positive direction around the assembly mechanism 3. After the water is stopped, when the baffle mechanism 2 moves away from the outlet 12, the moving part 21 moves along the negative guide surface of the first guide part 311, so that the baffle mechanism 2 continues to rotate in the positive direction around the assembly mechanism 3.

[0068] This design causes the first guide portion 311 and the second guide portion 321 to be misaligned in the circumferential direction, while their guide surfaces have opposite orientations. Specifically, the first guide portion 311 has a reverse guide surface, namely the first guide surface 3111, while the second guide portion 321 has a forward guide surface, namely the second guide surface 3211. This design cleverly utilizes the reciprocating motion of the baffle mechanism 2, converting it into rotation around the assembly mechanism 3 in the same direction, either clockwise or counterclockwise.

[0069] Because the first guide section 311 and the second guide section 321 are circumferentially intersecting and have opposite guide surfaces, the baffle mechanism 2 does not reverse its rotation direction during the return process, but continues to rotate forward around the assembly mechanism 3. This ensures that the baffle mechanism 2 maintains a consistent rotation direction during each reciprocating movement, thereby achieving automatic switching of the outlet 12.

[0070] Multiple water outlets 12 are evenly spaced apart. The sum of the inclination angles of the forward guiding surface and the reverse guiding surface is the switching angle of the water outlet 12.

[0071] Preferably, there are four outlets 12. Each time an outlet 12 is switched, it needs to be rotated 90 degrees, and the tilt angles of the forward guide surface and the reverse guide surface are 45°.

[0072] Specifically, when water intake stops, under the action of gravity or the elastic mechanism 4, the baffle mechanism 2 moves away from the outlet 12. During this process, the moving part 21 moves along the reverse guide surface of the first guide part 311 and continues to be subjected to a lateral force toward the center of the assembly mechanism 3, rotating 45° to reach... Figure 7 The intermediate state. When water re-enters, the moving part 21 slides along the positive guide surface of the second guide part 321 and continues to be subjected to a lateral force toward the center of the assembly mechanism 3, causing the baffle mechanism 2 to continue rotating 45° around the assembly mechanism 3 in the same direction, and gradually approaching the target outlet 12, eventually reaching... Figure 8 The work status.

[0073] Preferably, the inlet 11 is located on the side wall or bottom wall of the cavity 1, and the outlet 12 is located on the side wall or top wall of the cavity 1.

[0074] Furthermore, the assembly mechanism 3 extends protrudingly along the reciprocating direction of the baffle mechanism 2. Multiple second guide structures are circumferentially spaced at one end of the assembly mechanism 3 near the outlet 12. Multiple first guide structures are circumferentially spaced at the other end of the assembly mechanism 3.

[0075] The assembly mechanism 3 not only serves as a support structure for the baffle mechanism 2, but also provides a clear guide path for the movement of the baffle mechanism 2 through its protruding design along the reciprocating direction of the baffle mechanism 2. This protruding design helps ensure the stability and accuracy of the baffle mechanism 2 during movement, reducing the problem of inaccurate switching of the outlet 12 caused by shaking or deviation.

[0076] In the initial state, the moving part 21 is assembled in the gap between two adjacent first guide structures. In the working state, the moving part 21 is assembled in the gap between two adjacent second guide structures.

[0077] On the assembly mechanism 3, multiple second guide structures are spaced apart circumferentially at one end near the outlet 12, while multiple first guide structures are spaced apart circumferentially at the other end of the assembly mechanism 3. This circumferentially spaced arrangement not only achieves the staggered arrangement of the guide surfaces, but also ensures that the baffle mechanism 2 can smoothly transition during rotation, avoiding impacts or jamming caused by sudden changes in the guide surfaces.

[0078] In the initial state, i.e., when the dishwasher is not in operation, the moving part 21 is fitted into the gap between the two adjacent first guide structures. This design allows the baffle mechanism 2 to maintain a stable initial position when stationary, preparing for the subsequent switching of the water outlet 12.

[0079] When the dishwasher starts operating, the water flow drives the baffle mechanism 2 to move towards the outlet 12 (upwards). The moving part 21 moves from the gap between the two first guide structures to the second guide mechanism, moves along the forward guide surface of the second guide structure, and then enters the gap between two adjacent second guide structures. During this process, the baffle mechanism 2 is acted upon by the guide surface and rotates forward around the assembly mechanism 3 until it reaches the target outlet 12 position.

[0080] In the working state, when the baffle mechanism 2 has switched to the target outlet 12 and is in a stable state, the moving part 21 remains in the gap between the two adjacent second guide structures, preventing the baffle mechanism 2 from continuing to rotate. At this time, the baffle mechanism 2 can effectively prevent water from entering other outlets 12, ensuring that the water can flow accurately and efficiently to the target cleaning area.

[0081] The guide portion has guide surfaces that extend in the same direction along the reciprocating movement direction from both ends of the guide surface.

[0082] The first guide surface 3111 and the second guide surface 3211 are inclined in opposite directions, and their projections on the same horizontal plane do not overlap.

[0083] The two first guide surfaces 3112 of the first guide portion 311 and the two second guide surfaces 3212 of the second guide portion 321 extend in opposite directions, so that when the water inlet drive is activated, the guide moving portion 21 moves linearly to the guide surface of the second guide portion 321, and when the water inlet drive is stopped, the guide moving portion 21 moves linearly to the guide surface of the first guide portion 311.

[0084] The guide surfaces of the first guide section 311 and the second guide section 321 are inclined in opposite directions, and their guide surfaces extend in opposite directions. This design allows the moving part 21 to automatically and effectively switch between the first guide surface 3111 of the first guide section 311 and the second guide surface 3211 of the second guide section 321 during water inlet or stop operation, thus switching the water outlet 12. The self-locking and unlocking mechanism of the mechanical structure ensures the accuracy and reliability of the water outlet 12 switching, and its simple and efficient working principle allows the entire water distribution device to operate stably and smoothly during the dishwasher's operation.

[0085] In addition to straight inclined guide surfaces, the guide surfaces can also be curved, polygonal, or other complex shapes to optimize the movement trajectory and switching efficiency of the moving part 21.

[0086] The principle of this invention lies in the ingenious design of the mechanical structure, which transforms the linear reciprocating motion of the water flow into the circumferential rotational motion of the moving part 21. When the water flow begins to enter the water distribution device, the driving force it generates propels the moving part 21 along the first guide surface 3112. As the water flow continues, the moving part 21 gradually overcomes the initial resistance and slides along the guide surface to the second guide surface 3211. When the water flow stops, the moving part 21 returns to the first guide surface 3111 along the second guide surface 3212 under the action of gravity or a reset mechanism such as the spring 43, completing one complete outlet 12 switching cycle.

[0087] Furthermore, the baffle mechanism 2 includes a rotating base 22 and a baffle 23. The rotating base 22 may be cylindrical or have other suitable shapes.

[0088] The baffle 23 is sleeved on the outer periphery of one end of the rotating seat 22. The moving part 21 protrudes from the inner or outer peripheral wall of the rotating seat 22. The rotating seat 22 is sleeved on the outer periphery of the assembly mechanism 3 or inserted into the inner peripheral wall of the assembly mechanism 3.

[0089] Preferably, the rotating seat 22 can be cylindrical or have other suitable shapes.

[0090] The moving part 21 has a sliding surface that matches the guide surface, and the moving part 21 is a triangular slider.

[0091] To ensure that the baffle mechanism 2 can smoothly return to its initial state after the water inlet drive is stopped, the water distribution device of the present invention includes an elastic mechanism 4.

[0092] The elastic mechanism 4 presses against the assembly mechanism 3 and the rotating seat 22 to provide a reset force for the baffle mechanism 2 to return to its initial state after the water inlet driving baffle mechanism 2 is stopped, thus preparing for the next switch of the outlet 12.

[0093] Preferably, the rotating base 22 has a mounting cavity 221 inside for accommodating the elastic mechanism 4. One end of the rotating base 22 has an opening 222 communicating with the mounting cavity 221. The protruding end of the assembly mechanism 3 extends into one end of the rotating base 22, and the elastic mechanism 4 abuts against the protruding end of the assembly mechanism 3 and the other end inside the rotating base 22.

[0094] The elastic mechanism 4 includes a fixed base 41, a movable base 42, and a spring 43. The fixed base 41 is fixedly disposed at the other end of the rotating base 22, and the movable base 42 is telescopically disposed with respect to the fixed base 41 via the spring 43. The end face of the protruding end of the assembly mechanism 3 is a pressing part 312, which presses against the movable base 42.

[0095] Preferably, the fixed seat 41 seals the opening 222 at the other end of the rotating seat 22. The top of the movable seat 42 is recessed, and the pressing part 312 at least partially matches the recessed area of ​​the movable seat 42, pressing against the recessed area.

[0096] The outer periphery of the baffle 23 has a downward-facing flange for sealing with the peripheral wall of the cavity 1.

[0097] The assembly mechanism 3 includes a first assembly 31 and a second assembly 32. The second assembly 32 is fitted and fixed to the top wall of the cavity 1, and the first assembly 31 is circumferentially limited and passes through the second assembly 32 to connect with the top wall of the cavity 1. The first guide part 311 and the second guide part 321 are respectively protruding from the outer peripheral walls of the first assembly 31 and the second assembly 32.

[0098] Furthermore, the water distribution device includes a valve body 13 and a valve cover 14.

[0099] The inlet 11 is located on the outer peripheral wall of the bottom of the valve body 13, and is used for circumferential flow after water enters. Multiple outlets 12 are circumferentially spaced on the valve cover 14. The baffle mechanism 2 is provided with an outlet 231. After being guided by the guide part under the drive of water flow, the baffle mechanism 2 covers the valve cover 14. The outlet 231 is connected to an outlet 12.

[0100] The valve cover 14 includes a cover body 141 and a ring portion 142, one end of which is connected to the outer periphery of the cover body 141. A sealing ring is provided around the outer periphery of the outlet 12 at the bottom of the valve cover 14. After the baffle 23 moves upward, it enters the ring portion 142, and the flange of the baffle 23 seals against the inner peripheral wall of the ring portion 142. Simultaneously, the top wall of the baffle 23 is sealed to other outlets 12 besides the predetermined outlet 12.

[0101] The valve body 13 has a transverse water inlet channel on its side wall, which communicates with the cavity 1. Preferably, the water inlet channel is tangent to or intersects with the outer peripheral wall of the cavity 1.

[0102] The water inlet channel communicates with the side wall of the cavity 1 (i.e., the side wall of the valve body 13). A vertical partition plate 15 extends circumferentially from the water inlet channel. The partition plate 15 can guide the water flow to form a circumferential flow and help the baffle plate 23 rotate while the water flows upward.
