Abstract

A material cleaning device and a cooking appliance. The material cleaning device comprises: a cleaning chamber, an air inlet, a material inlet, and a water inlet being provided on the cleaning chamber, the air inlet, the material inlet, and the water inlet being respectively used for transporting air flows, a material to be cleaned, and water for cleaning the material to the cleaning chamber; and a stirring assembly provided in the cleaning chamber and being capable of rotating in the cleaning chamber under the action of the air streams, so as to stir the material and the water in the cleaning chamber. The material cleaning device drives the stirring assembly to rotate by means of air streams, so as to make the stirring assembly stir the material and the water in the cleaning chamber, thereby implementing automatic cleaning. The material cleaning device features a simple structure, and is easy to use.

First claim

What is claimed is:

a stirring rod connected to the connecting rod, extending in a different direction from the connecting rod, and configured to stir the material and the water in the cleaning chamber.

3. The material cleaning device according to claim 2 , wherein
the connecting rod longitudinally passes through the first connecting hole, and upper and lower ends of the connecting rod are connected to the rotating member and the stirring rod, respectively; or
an upper end of the connecting rod protrudes from the first connecting hole, the rotating member and the stirring rod are both connected to an upper portion of the connecting rod, and the stirring rod is located below the rotating member.

4. The material cleaning device according to claim 3 , wherein
the rotating member is provided with a second connecting hole, and a sidewall of the second connecting hole is provided with a limiting groove; and
a first limiting bump is formed on the upper end of the connecting rod, and the first limiting bump is inserted into the second connecting hole, is clamped in the limiting groove, and is supported on a groove bottom of the limiting groove, wherein the connecting rod is fixedly connected with the rotating member.

5. The material cleaning device according to claim 3 , wherein
the lower end of the connecting rod protrudes from the first connecting hole, and the lower end of the connecting rod is formed with a second limiting bump having a larger cross-sectional area than the first connecting hole.

6. The material cleaning device according to claim 2 , wherein
the stirring rod extends in a direction close to the bottom of the inner sidewall of the cleaning chamber.

7. The material cleaning device according to claim 6 , further comprising:
a plurality of stirring rods, wherein the plurality of stirring rods each form a different angle with respect to the connecting rod.

8. The material cleaning device according to claim 2 , wherein the bracket comprises:

9. The material cleaning device according to claim 8 , wherein,
the support column, the support rib and the cleaning chamber are a one-piece structure; or
a plurality of support ribs are uniformly distributed in a circumferential direction of the support column.

10. The material cleaning device according to claim 1 , wherein the rotating member comprises:
a connecting column connected to the stirring member configured to be supported by the bracket; and
a blade connected to the connecting column and configured to cover wind energy into mechanical energy to enable the rotating member to rotate relative to the bracket.

11. The material cleaning device according to claim 10 , further comprising:
a plurality of blades, wherein the plurality of blades are uniformly distributed in a circumferential direction of the connecting column; or
a windward side of the blade is a cambered surface.

12. The material cleaning device according to claim 1 , wherein
the bottom of the cleaning chamber is provided with a material outlet; and
the material cleaning device further comprises a valve connected to the cleaning chamber and movable relative to the cleaning chamber to close or open the material outlet, wherein the bottom of the cleaning chamber is completely opened to form the material outlet.

13. The material cleaning device according to claim 12 , wherein,
a sealing member for sealing the material outlet is further provided between the valve and the cleaning chamber, and wherein the sealing member is a sealing ring.

14. The material cleaning device according to claim 1 , wherein
a top of the cleaning chamber is completely open; and
the material cleaning device further comprises a cleaning cover configured to cover the cleaning chamber to close the cleaning chamber.

15. The material cleaning device according to claim 1 , wherein
the air inlet coincides with the material inlet or the water inlet.

16. The material cleaning device according to claim 1 , wherein
the cleaning chamber is further provided with an air outlet and a water outlet, wherein
