Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a filter device and dishwasher for a dishwasher. Background Technology

[0002] With the improvement of people's living standards and the change of consumption concepts, dishwashers have gradually entered many households and become one of the mainstream kitchen appliances.

[0003] Currently, dishwasher filter systems generally consist of a flat filter, a microfilter, and a cup holder. The cup holder is installed inside the microfilter to form a filter assembly. The filter assembly is fixed to the water cup and the inner tank respectively by a bottom screw fastener.

[0004] During the washing cycle of a dishwasher, due to the strong suction of the washing pump, a lot of small particulate contaminants will adhere to the filter. Over time, the contaminants will accumulate, affecting the washing area and causing bacteria to grow. Therefore, the filter often needs to be manually removed for cleaning before it can be reinstalled.

[0005] In the existing technology, most filter installation structures have the following shortcomings:

[0006] 1. The filter and water cup are installed using a screw-on fastener. The filter needs to be inserted into the cup in a specific direction first, and then rotated to lock it in place. This process is rather cumbersome and difficult for users. Furthermore, the screw-on fastener requires considerable force to ensure proper installation, which can easily lead to improper installation. This not only affects normal use but also results in a poor user experience.

[0007] 2. Because the filter and water cup are connected by a screw fastener, the fastener is relatively flimsy and is frequently disassembled and installed. In addition, the dishwasher's long-term high-temperature washing can cause the fastener to wear out, deform, or even break, resulting in the machine becoming unusable, a poor user experience, and inconvenient repairs.

[0008] Therefore, it is necessary to design a new type of dishwasher filter system to solve existing technical problems and improve the user experience. Summary of the Invention

The components of the embodiments of this utility model can be arranged and designed in various different configurations.

[0035] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of the claimed invention.

[0036] Example:

[0037] like Figures 1 to 4 As shown, this embodiment provides a filter device for a dishwasher, including:

[0038] Water cup 1 has an upward-opening water collection cavity inside the water cup 1, and a boss 11 is provided at the bottom of the water collection cavity, and a mating part 12 is provided on the boss 11.

[0039] Microfilter 2, with a mounting base provided at its lower end;

[0040] The snap-fit ​​assembly 3 is disposed on the mounting base and is connected to the mating part 12 so that the mounting base is sleeved on the boss 11, thereby detachably installing the microfilter 2 in the water collection chamber.

[0041] In this embodiment, a water collection cavity with an upward opening is defined inside the water cup 1. A boss 11 is provided at the bottom of the water collection cavity, and a mating part 12 is provided on the boss 11. A mounting seat that mates with the boss 11 is provided at the lower end of the microfilter 2, and a snap-fit ​​assembly 3 is provided on the mounting seat. When the microfilter 2 enters the water collection cavity from top to bottom through the opening end of the water collection cavity, the snap-fit ​​assembly 3 and the mating part 12 are engaged and connected so that the mounting seat is fitted onto the boss 11, thereby detachably installing the microfilter 2 in the water collection cavity. Its structure is simple and easy to disassemble and assemble, which can effectively reduce the difficulty of disassembling and assembling the product, thereby further improving the disassembly and assembly efficiency.

[0042] Furthermore, the snap-fit ​​assembly 3 includes a spring 31 and a ball 32. A groove is recessed along the circumferential direction on the outer wall of the boss 11 to form a mating part 12. A plurality of mounting cavities 22 are spaced along the circumferential direction on the inner wall of the mounting base. The mounting cavity 22 is open at one end near the mounting base. One end of the spring 31 abuts against the closed end of the mounting cavity 22, and the other end abuts against the ball 32 to limit the ball 32 at the open position of the mounting cavity 22. The end of the ball 32 away from the spring 31 abuts against the mating part 12 so that the mounting base snaps onto the boss 11.

[0043] Preferably, the snap-fit ​​assembly 3 further includes a mounting cover 33, and a mounting opening communicating with the mounting cavity 22 is provided on the bottom wall of each mounting cavity 22. The mounting cover 33 is detachably disposed at the mounting opening position.

[0044] In this embodiment, a mounting base with a channel structure is provided at the lower end of the microfilter 2, so that the mounting base can be connected to the boss 11. Multiple mounting cavities 22 are provided at intervals along the circumferential direction on the inner side wall of the mounting base. The mounting cavity 22 is open at the end near the boss 11, that is, the mounting cavity 22 has an opening at the end near the boss 11, and the mounting cavity 22 is closed at the end away from the boss 11. Since the ball 32 is movably disposed at the open end of the mounting cavity 22, one end of the spring 31 abuts against the closed end of the mounting cavity 22, and the other end abuts against the ball 32 to limit the ball 32 at the open end of the mounting cavity 22. Since a groove is recessed along the circumferential direction on the outer side wall of the boss 11 to form a mating part 12, the end of the ball 32 away from the spring 31 abuts against the mating part 12 so that the mounting base is snapped onto the boss 11. Since the ball bearing 32 can roll 360°, it avoids the problem of excessive force or difficulty in installation of the microfilter 2 during disassembly and assembly due to friction. On the other hand, by adopting the flexible fit of the ball bearing 32, it avoids wear and damage to the microfilter 2 during long-term disassembly and assembly, thereby effectively improving the service life of the product.

[0045] More preferably, when installing the microfilter 2, the microfilter 2 is slightly pressed down by external force to drive it from top to bottom through the opening of the water collection chamber. The ball 32 is then pressured by the outer wall of the boss 11, causing the spring 31 to contract until the ball 32 rolls into the groove of the boss 11. At this point, the spring 31 returns to its original position so that the groove holds the ball 32 in place. That is, the end of the ball 32 away from the spring 31 abuts against the mating part 12. With the cooperation of the ball 32 and the groove, the microfilter 2 is mounted on the boss 11, thereby fixing the microfilter 2 in the water collection chamber. In addition, when removing the microfilter 2, it can be lifted directly by external force. During the lifting process, the ball 32 compresses the spring 31 to contract. When the ball 32 rolls out of the groove, the ball 32 is disconnected from the mating part 12, thereby separating the microfilter 2 from the water cup 1, and thus completing the disassembly of the water cup 1 and the microfilter 2.

[0046] In this embodiment, the number of mounting cavities 22 can be two or more. This solution uses four cavities for description, and the others will not be described in detail. This makes the fit between the microfilter 2 and the water cup 1 more secure. At the same time, since the groove is set on the outer wall of the boss 11, the microfilter 2 is not restricted by direction during installation. The microfilter 2 can be quickly installed in the water collection cavity of the water cup 1 from any direction.

[0047] In this embodiment, an installation port communicating with the installation cavity 22 is provided on the bottom wall of each installation cavity 22. The spring 31 and the ball 32 can be installed in the installation cavity 22 through the installation port. Then, by detachably setting the installation cover 33 at the installation port position, the assembly of the spring 31 and the ball 32 can be completed.

[0048] Furthermore, it also includes a lifting cup 4, which defines a slag collection chamber with an open upper end within the microfilter 2, and the lifting cup 4 is detachably fitted inside the slag collection chamber.

[0049] Preferably, it also includes a filter screen, which is disposed on the outer wall of the slag collection chamber.

[0050] Specifically, it also includes an inner liner 6, which is formed by defining a cleaning chamber within the dishwasher, and a water cup 1 is located at the lower end of the inner liner 6.

[0051] Preferably, it also includes an inner water pipe 7, which is connected to the inner liner 6 and the water cup 1 respectively.

[0052] Furthermore, it also includes a flat filter 8, which is disposed inside the inner liner 6 and located above the fixed base, and has several water passage holes.

[0053] Specifically, it also includes a spray arm support 9, which is mounted on the water cup 1, and the water inlet end of the spray arm support 9 is connected to the inner water pipe 7.

[0054] In this embodiment, a cleaning chamber is defined inside the dishwasher to form an inner tank 6. A water cup 1 is located at the lower end of the inner tank 6. The microfilter 2 is driven to enter the water collection chamber from top to bottom through the opening end of the water collection chamber by a slight downward press of an external force. With the cooperation of the ball bearing 32 and the groove, the mounting seat is fitted onto the boss 11, thereby fixing the microfilter 2 in the water collection chamber. Secondly, since a slag collection chamber with an open upper end is defined inside the microfilter 2, the lifting cup 4 is detachably fitted into the slag collection chamber. A flat filter 8 is provided above the fixing seat and above the water cup 1. Several water passage holes are opened on the flat filter 8.

[0055] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
