Abstract

Disclosed is a dishwasher (10). The dishwasher (10) comprises a body (101), an air passage (102), catalyst pieces (103) having nanometer titanium dioxide, and an ultraviolet lamp (104) used for emitting ultraviolet light to the catalyst pieces (103). An accommodating cavity (1011) used for accommodating tableware is defined in the body (101). A gas inlet (1012) and a gas outlet (1013) are defined in the wall of the accommodating cavity (1011). An air outlet of the air passage (102) is in communication with the gas inlet (1012), and an air inlet of the air passage (102) is in communication with the gas outlet (1013). The catalyst pieces (103) are disposed in the air passage (102). The ultraviolet lamp (104) is disposed in the air passage (102).

First claim

What is claimed is:

1. A dishwasher, comprising:
a body defining an accommodating cavity used to accommodate tableware, a wall of the accommodating cavity defining a gas inlet and a gas outlet;
an air passage having an air outlet in communication with the gas inlet, and an air inlet in communication with the gas outlet;
a catalyst piece having nanometer titanium dioxide and provided in the air passage; and
an ultraviolet lamp configured to emit ultraviolet light to the catalyst piece and provided in the air passage;
wherein a plurality of catalyst pieces are provided and spaced apart along a length direction of the ultraviolet lamp, and a length direction of each catalyst piece is perpendicular to the length direction of the ultraviolet lamp.

2. The dishwasher according to claim 1 , wherein the gas inlet is defined in a peripheral wall of the accommodating cavity and adjacent to a bottom wall of the accommodating cavity, and the gas outlet is defined in the peripheral wall of the accommodating cavity and adjacent to a top wall of the accommodating cavity.

3. The dishwasher according to claim 1 , wherein the catalyst piece comprises a substrate and a nanometer titanium dioxide coating applied on the substrate.

4. The dishwasher according to claim 1 , further comprising a fan provided in the air passage.

5. The dishwasher according to claim 4 , wherein a plurality of fans are provided.

6. The dishwasher according to claim 1 , further comprising a fan, wherein the air passage comprises a first sub air passage and a second sub air passage, the first sub air passage has an air inlet in communication with the gas outlet and an air outlet in communication with an air inlet of the fan, and the second sub air passage has an air inlet in communication with an air outlet of the fan and an air outlet in communication with the gas inlet.

7. The dishwasher according to claim 6 , wherein the catalyst piece and the ultraviolet lamp are provided in the second sub air passage.

8. The dishwasher according to claim 7 , wherein the second sub air passage comprises:
a first connecting segment having a first end connected with the air outlet of the fan;
a second connecting segment having a first end connected with the gas inlet;
an expanding segment having a first end connected with a second end of the first connecting segment;
a receiving segment having a first end connected with a second end of the expanding segment, the catalyst piece and the ultraviolet lamp being arranged in the receiving segment; and
a narrowing segment having a first end connected with a second end of the receiving segment and a second end connected with a second end of the second connecting segment,
wherein a diameter of the receiving segment is equal to a maximum diameter of the expanding segment and a maximum diameter of the narrowing segment.
