[0001] The utility model relates to the technical field of dishwashers, and particularly relates to a filtering structure for a dishwasher. Background Art

[0002] Inside a household kitchen, a dishwashing machine is an essential device for efficiently cleaning and disinfecting used tableware. Traditional dishwashing machines usually include components such as a water pump, a spraying system, a washing tank, a rinsing tank, and a drying device. Its working principle is to wash away the dirt on the surface of the tableware through the action of water flow and detergent, and complete the final cleaning and disinfection process through the rinsing and drying steps.

[0003] However, in traditional dishwashing machines, there are often some deficiencies in the internal filtering structure:

[0004] Low filtering efficiency: Traditional filtering structures often have only a single filtering layer, with a limited filtering area, which easily causes blockage and accumulation of solid particles, affecting the cleaning effect and the stable operation of the equipment.

[0005] Insufficient anti-blocking ability: Due to the design of a single filtering layer, blockage is likely to occur inside traditional dishwashing machines, resulting in the equipment stopping working or the cleaning effect deteriorating, requiring frequent maintenance and cleaning, which increases the operation cost and the maintenance burden.

[0006] Therefore, this solution specifically proposes a filtering structure for a dishwasher to solve the above problems. Content of the Utility Model

[0045] The following will further describe the present utility model in detail with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the utility model without creative efforts shall fall within the protection scope of the utility model.

[0046] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the utility model, the directional indications are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0047] In addition, "a plurality of" means two or more. In addition, the technical solutions between the embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions conflicts with each other or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the utility model.

[0048] Please refer to the accompanying specification Figures 1 - 7 , the present utility model provides a filtering structure for a cleaning machine. Its fixed outer shell 1 is designed as a square tube shape that penetrates up and down. The internal structure from top to bottom is a top grid plate 2, a waste residue blocking component 7, and a filtering component 9 in sequence. The top grid plate 2 has evenly distributed grids for initially intercepting larger solid particles. The waste residue blocking component 7 includes a horizontally distributed wavy filter core plate 71, and its wavy design increases the filtering area and improves the blocking efficiency. The side slag collection box 72 is located on the front and rear sides of the wavy filter core plate 71 for collecting the waste residue pushed by the pushing plate 3. The shape of the bottom edge of the pushing plate 3 is consistent with the top structure of the wavy filter core plate 71 to ensure that the waste residue can be effectively pushed into the side slag collection box 72 when sliding back and forth.

[0049] The pushing driving mechanism 4 includes a longitudinal mounting frame 41 installed at the center of the bottom of the top grid plate 2. The reciprocating driving lead screw 42 is installed inside the longitudinal mounting frame 41. Driven by the reciprocating driving motor 43, the lead screw can rotate forward and backward, thereby driving the lead screw sleeve 44 and the pushing plate 3 to move back and forth. The lead screw sleeve 44 is fixedly connected to the center of the top of the pushing plate 3, ensuring that the moving track of the pushing plate 3 is synchronized with the movement of the lead screw sleeve 44, and further realizing the operation of preventing blockage by reciprocating pushing back and forth.

[0050] At the bottom edge of the top grid plate 2, a guiding component 5 is provided to ensure the accuracy and stability of the pusher plate 3 during forward and backward sliding. The internal side mounting box 51 is fixed at one edge of the top grid plate 2, and a guiding rod 52 is installed inside. The guiding rod 52 is a smooth metal rod, reducing sliding friction. The guiding sleeve 53 is slidably sleeved on the guiding rod 52, and the bottom pipe wall thereof is connected to the top of the same-side end of the pusher plate 3, providing sliding guidance for both ends of the pusher plate 3 and ensuring the stability of the forward and backward sliding of the pusher plate 3.

[0051] Inside the fixed housing 1, a first boss 6 and a second boss 8 in the shape of a square box are installed. These two bosses provide a stable support platform to ensure the correct installation positions of the waste residue blocking component 7 and the filtering component 9. The waste residue blocking component 7 is lapped on the top of the first boss 6, and the filtering component 9 is lapped on the top of the second boss 8. Such a design makes the filtering structure distinct in levels, facilitating maintenance and replacement.

[0052] The filtering component 9 is composed of a first fine filtering plate 91 and a second fine filtering plate 92 stacked up and down. These two layers of filtering plates have different pore sizes. The first fine filtering plate 91 has a larger pore size for intercepting medium-sized particles, and the second fine filtering plate 92 has a smaller pore size for intercepting finer particles, ensuring the final cleanliness of the cleaning water. This double-layer filtering design improves the filtering efficiency and extends the service life of the filtering component.

[0053] Working Principle

[0054] When the cleaning machine starts to work, the water flow and detergent mixture enter the filtering structure through the top of the fixed housing 1.

[0055] First, the larger solid particles in the water flow are intercepted by the evenly distributed grids on the top grid plate 2, preventing these large particles from entering the lower filtering component.

[0056] The water flow that has been preliminarily filtered by the top grid plate 2 continues to flow downward and encounters the waste residue blocking component 7 to further intercept medium-sized solid particles.

[0057] Under the action of the pusher driving mechanism 4, the pusher plate 3 drives the screw rod sleeve 44 and the pusher plate 3 to move forward and backward through the forward and reverse rotation of the reciprocating driving screw rod 42, effectively pushing the waste residue blocked on the corrugated filter core plate 71 into the side slag collection boxes 72 at the front and back.

[0058] The water flow that has been filtered by the waste residue blocking component 7 continues to flow downward and reaches the filtering component 9. The first fine filtering plate 91 intercepts medium-sized particles, and the second fine filtering plate 92 intercepts finer particles, ensuring the final cleanliness of the cleaning water.

[0059] After the cleaning machine finishes working, pull out the internal waste residue blocking component 7 and the filtering component 9 to clean and collect the waste residue, and replace or clean the filtering component 9 as needed to maintain the filtering efficiency and extend the service life.

[0060] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
