Description

Technical Field

[0001] This utility model relates to the field of dishwasher filtration technology, and in particular to a filter basket structure for dishwashers. Background Technology

[0002] A dishwasher is a kitchen appliance used to automatically clean dishes. There are many types of dishwashers, and ultrasonic dishwashers are one of them. In order to intercept food residue, crumbs, bones and other impurities washed off the dishes and prevent them from entering the drain pipe and causing blockage, a filter basket is installed at the drain outlet. Therefore, the filter basket is a very important part of the dishwasher.

[0003] Currently, existing filter baskets are directly inserted into the drain outlet. When the ultrasonic dishwasher is working, it generates high-frequency vibrations, which cause the filter basket to be subjected to an upward force, making it float. At this time, its ability to intercept impurities in the water is greatly reduced, and food scraps can easily enter the drain pipe directly through the drain outlet, thus increasing the risk of pipe blockage. To address this issue, we propose a new filter basket structure for dishwashers. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a filter basket structure for dishwashers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 A dishwasher filter basket structure includes a dishwasher body 1. The dishwasher body 1 has a drain outlet 2 inside, and a filter basket body 3 is inserted inside the drain outlet 2. The working principle of the dishwasher body 1 and the drain outlet 2 is prior art and will not be described in detail here. A limiting frame 4 is welded to the top of the filter basket body 3, and an insertion block 5 is symmetrically connected to the bottom of the limiting frame 4. The insertion block 5 has a receiving groove inside. The dishwasher body 1 has a mating groove that matches the insertion block 5. Threaded grooves are symmetrically formed inside the limiting frame 4, and threaded rods 6 are inserted into each of the threaded grooves. A sealing gasket is installed at the position corresponding to the threaded groove on the upper part of the limiting frame 4. The gasket is usually made of rubber, silicone, or other materials with good elasticity and sealing properties. When the threaded rod 6 pushes the pushing block 7 downward, the rotating block 12 connected above the threaded rod 6 will abut against the gasket, thereby filling the gap between the threaded rod 6 and the threaded groove, effectively preventing... The residue leaks into the receiving groove. The bottom end of the threaded rod 6 extends into the interior of the receiving groove and is connected to the push block 7 via a bearing. Trapezoidal blocks 8 are distributed on the side of the push block 7, and the bottom end of the trapezoidal blocks 8 is connected to the connecting spring 10 via a rotating plate 9. The side of the push block 7 is set to be inclined, so when the push block 7 moves down, it can squeeze the two sets of trapezoidal blocks 8 away from each other and embed them into the positioning holes opened inside the dishwasher body 1. When the threaded rod 6 drives the push block 7 to lift up, the two sets of trapezoidal blocks 8 can be reset and brought closer to each other by the elastic force of the rotating plate 9, so that the two trapezoidal blocks 8 can be embedded into the receiving groove opened inside the insertion block 5, thereby releasing the restriction on the filter basket body 3. In addition, the other end of the connecting spring 10 of the limiting frame 4 is connected to the inner wall of the receiving groove. The side of the trapezoidal block 8 away from the push block 7 extends through the inner wall of the insertion block 5 into the dishwasher body 1, and the interior of the dishwasher body 1 is provided with positioning holes that are adapted to the trapezoidal blocks 8.

[0024] Furthermore, refer to Figure 4It can be seen that a rubber frame 13 is connected to the edge of the filter basket body 3, and a sealing groove adapted to the rubber frame 13 is opened inside the dishwasher body 1. The rubber frame 13 and the sealing groove are set as a U-shaped structure. Through the cooperation of the two, it can further prevent residue from entering the receiving groove, so as to ensure the normal use of the threaded rod 6 in the future.

[0025] Furthermore, refer to Figure 4 It can be seen that the top of the threaded rod 6 is connected to a rotating block 12, and the outer side of the rotating block 12 is evenly connected to a connecting plate. During use, the rotating block 12 and the connecting plate cooperate with each other, which makes it easy for the operator to quickly rotate the threaded rod 6, thereby effectively improving the convenience of using the device.

[0026] Furthermore, refer to Figure 4 It can be seen that the upper part of the push block 7 is connected to the linkage plate 11, and the inside of the filter basket body 3 is provided with an insertion slot that matches the linkage plate 11. During use, the vertical guidance of the push block 7 can be achieved through the cooperation of the linkage plate 11 and the insertion slot, thereby effectively ensuring the stable up and down sliding of the push block 7.

[0027] Furthermore, refer to Figure 4 It can be seen that there are two sets of trapezoidal blocks 8, and the two sets of trapezoidal blocks 8 are symmetrically distributed about the central axis of the threaded rod 6. By setting the two sets of trapezoidal blocks 8, the limiting effect of the limiting frame 4 can be effectively guaranteed.

[0028] Furthermore, refer to Figure 3 It can be seen that a handle 14 is connected to the inner wall of the filter basket body 3, and a rubber sleeve is glued to the outer surface of the handle 14. Through the cooperation of the handle 14 and the rubber sleeve, it is easy for the staff to pull the filter basket body 3 out of the drain outlet 2 for dumping.

[0029] Furthermore, refer to Figure 4 It can be seen that the rotating plate 9 is set as a long strip structure, and the outer wall of the rotating plate 9 abuts against the inner wall of the receiving groove. The rotating plate 9, set as a long strip structure, can effectively ensure the stable lateral movement of the rotating plate 9.

[0030] Working Principle: When using this invention, the operator first places the device in a suitable position, then inserts the filter basket body 3 into the drain outlet 2. At this time, the insertion block 5 connected to the bottom end of the limiting frame 4 is inserted into the docking groove opened inside the dishwasher body 1. Then, the operator can rotate the rotating block 12 in sequence, which will drive the threaded rod 6 to rotate simultaneously, thereby causing the pushing block 7 to be pushed down. At this time, the two sets of trapezoidal blocks 8 distributed on the outer side of the pushing block 7 move away from each other and are embedded in the positioning holes opened inside the dishwasher body 1. After completing the rotation of the two sets of rotating blocks 12, the vertical movement of the filter basket body 3 can be achieved. After the limit is set, the operator fills the dishwasher body 1 with water and puts the dishes and chopsticks to be washed into the dishwasher body 1. Then the dishwasher body 1 can be connected to the power supply to clean the dishes and chopsticks. After cleaning, the operator can rotate the rotating block 12 in the opposite direction, thereby driving the pushing block 7 to rise. At this time, the two sets of trapezoidal blocks 8 can approach each other through the elastic force of the connecting spring 10 and be pulled out from the positioning hole opened inside the dishwasher body 1. Then the operator can pull up the handle 14 to remove the filter basket body 3 from the inside of the drain outlet 2 and empty the debris carried inside the filter basket body 3. The above is the entire working principle of this utility model.
