Abstract
A filtering device and a tableware washing apparatus, the filtering device includes a rotary filter and a drive assembly. The rotary filter includes a columnar filtering screen configured to filter water from a washing process of the tableware washing apparatus; wherein a diameter of an external circle defined by each mesh of the columnar filtering screen is between 0.2 to 0.5 mm. The drive assembly is connected to the rotary filter and configured to drive the columnar filtering screen to rotate relative to contents within the columnar filtering screen at a relative speed of 100 to 1000 r/min, for separating at least a portion of residue on the columnar filtering screen from the columnar filtering screen.
Claims18
A filtering device for a tableware washing apparatus, comprising:
- a rotary filter comprising a columnar filtering screen configured to filter water from a washing process of the tableware washing apparatus, wherein a diameter of an external circle defined by each mesh of the columnar filtering screen is between 0.2 to 0.5 mm;
- and
- a drive assembly, connected to the rotary filter and configured to drive the columnar filtering screen to rotate relative to contents within the columnar filtering screen at a relative speed of 100 to 1000 r/min, configured to separate at least a portion of a residue on the columnar filtering screen from the columnar filtering screen, wherein the rotary filter further comprises a cleaning element, and the cleaning element is in contact with an inner wall of the columnar filtering screen;
- and
- the drive assembly is connected to the cleaning element and configured to drive the cleaning element to rotate relative to the columnar filtering screen to separate at least a portion of the residue from the columnar filtering screen by rotating the cleaning element;
- and wherein the cleaning element comprises:
- a mounting bracket connected to the drive assembly and rotatable by the drive assembly;
- and a contact portion arranged on the mounting bracket and in contact with the inner wall of the columnar filtering screen, and wherein a height of the contact portion is between 40 to 60 mm, and a width of the contact portion is between 0.9 to 1.1 mm.
A filtering device for a tableware washing apparatus, comprising:
- a rotary filter comprising a columnar filtering screen configured to filter water from a washing process of the tableware washing apparatus, wherein a diameter of an external circle defined by each mesh of the columnar filtering screen is between 0.2 to 0.5 mm;
- and
- a drive assembly, connected to the rotary filter and configured to drive the columnar filtering screen to rotate relative to contents within the columnar filtering screen at a relative speed of 100 to 1000 r/min, configured to separate at least a portion of a residue on the columnar filtering screen from the columnar filtering screen, further comprising a water cup assembly, wherein the water cup assembly comprises:
- a cup, wherein the columnar filtering screen is accommodated in the cup, and the cup comprises a bottom surface;
- and
- a drive accommodating portion, connected to the cup and configured to accommodate at least a motor of the drive assembly;
- wherein the drive accommodating portion does not protrude from the bottom surface of the cup along an axial direction of the cup;
- or
- wherein the drive accommodating portion protrudes at least partially from the bottom surface of the cup along the axial direction of the cup, and a ratio of a protruding height of a bottom surface of the drive accommodating portion relative to the bottom surface of the cup to a height of the motor is less than 1:1.
A filtering device for a tableware washing apparatus, comprising:
- a rotary filter comprising a columnar filtering screen configured to filter water from a washing process of the tableware washing apparatus, wherein a diameter of an external circle defined by each mesh of the columnar filtering screen is between 0.2 to 0.5 mm;
- and
- a drive assembly, connected to the rotary filter and configured to drive the columnar filtering screen to rotate relative to contents within the columnar filtering screen at a relative speed of 100 to 1000 r/min, configured to separate at least a portion of a residue on the columnar filtering screen from the columnar filtering screen, further comprising:
- a plane filter, connected to the rotary filter and comprising:
- a face-shaped screen holder, defining a first opening, wherein the columnar filtering screen is disposed below the face-shaped screen holder and facing the first opening, for allowing the water to fall from the first opening into the columnar filtering screen below the face-shaped screen holder;
- and
- a first face-shaped screen and a second face-shaped screen arranged side by side in a first direction, wherein an area of the first face-shaped screen is greater than an area of the second face-shaped screen, a first angle is formed between the first face-shaped screen and a reference plane perpendicular to an axial direction of the first opening, and a second angle is formed between the second face-shaped screen and the reference plane, the first angle being less than the second angle.
