Abstract

The present disclosure provides a cooking appliance, comprising: a cooking system and a transport control system, wherein the cooking system comprises a cleaning device and a cooking cavity connected with the cleaning device; the cleaning device is provided with a first input port and a second input port; the transport control system comprises a material transport pipe, a water transport pipe and a drying device; the material transport pipe communicates with the first input port for transporting a foodstuff to be cleaned to the cleaning device; the water transport pipe communicates with the second input port for transporting water for cleaning the foodstuff to the cleaning device; and the drying device is connected with the material transport pipe for drying an inner wall surface of the material transport pipe.

First claim

What is claimed is:

1. A cooking appliance, comprising:
a cooking system, comprising:
a cleaning device and a cooking cavity connected to the cleaning device, wherein the cleaning device is provided with a first input port and a second input port; and
a transport control system, comprising:
a material transport pipe, a water transport pipe and a drying device, the material transport pipe communicates with the first input port for transporting a foodstuff to be cleaned to the cleaning device, the water transport pipe communicates with the second input port for transporting water for cleaning the foodstuff to the cleaning device, and the drying device is connected to the material transport pipe for drying an inner wall surface of the material transport pipe;
wherein the drying device comprises:
an air supply component, wherein an air supply outlet of the air supply component communicates with an inlet of the material transport pipe for supplying air into the material transport pipe; and
a heating component, arranged between the air supply component and the inlet of the material transport pipe for heating the air supplied by the air supply component to dry the inner wall surface of the material transport pipe.

2. The cooking appliance according to claim 1 , wherein,
the heating component is arranged at the air supply outlet of the air supply component.

3. The cooking appliance according to claim 1 , wherein,
the air supply component is a cyclone motor; and/or
the heating component is a resistance heating element.

4. The cooking appliance according to claim 1 , wherein the transport control system comprises:
a material transport device comprising a material transport component, the material transport pipe and the drying device, wherein the material transport component communicates with the inlet of the material transport pipe for transporting the foodstuff to be cleaned into the material transport pipe;
a waterway transport device comprising a water transport component and the water transport pipe, wherein the water transport component communicates with the inlet of the water transport pipe for transporting the water for cleaning the foodstuff into the water transport pipe; and
a control device connected with the material transport device and the waterway transport device for controlling the connection and disconnection of the material transport device and the waterway transport device.

5. The cooking appliance according to claim 4 , wherein the material transport component comprises:
a storage bin for storing the foodstuff, wherein the storage bin is provided with a discharge port;
a discharge pipe, wherein the inlet of the discharge pipe communicates with the discharge port, and an outlet of the discharge pipe communicates with the inlet of the material transport pipe; and
a first control component arranged on the discharge pipe and connected with the control device for controlling the connection and disconnection of the discharge pipe.

6. The cooking appliance according to claim 5 , wherein the material transport component further comprises:
a sensor weighing device connected with the storage bin and configured to weigh a total weight of the storage bin and the foodstuff in the storage bin.

7. The cooking appliance according to claim 5 , wherein,
the storage bin is funnel-shaped; and/or
the material transport pipe is a hose; and/or
the first control component is an electromagnetic ball valve.

8. The cooking appliance according to claim 4 , wherein the water transport component comprises:
a water supply component communicating with the inlet of the water transport pipe for supplying water to the water transport pipe; and
a second control component arranged on the water transport pipe and connected with the control device for controlling the connection and disconnection of the water transport pipe.

9. The cooking appliance according to claim 8 , wherein the water transport component further comprises:
a flowmeter arranged on the water transport pipe for detecting water volume passing through the water transport pipe.

10. The cooking appliance according to claim 8 , wherein
the water transport pipe is a hose; and/or
the second control component is an electromagnetic valve; and/or
the water supply component comprises a water pipe joint or a water tank, the water pipe joint is configured to be connected with an external water source to transport external water into the water transport pipe, and the water tank is configured to store the water for cleaning the foodstuff.

11. The cooking appliance according to claim 1 , wherein,
the cooking appliance is a rice cooker.

12. The cooking appliance according to claim 1 , wherein the air supply component is configured to:
when the cleaning device performs cleaning action, the air supply component blows air into the cleaning device to accelerate movement of the foodstuff and the water in the cleaning device.

13. The cooking appliance according to claim 1 , wherein the air supply component and the heating component are configured to:
before material transport, the air supply component and the heating component are simultaneously operated to dry the inner wall surface of the material transport pipe;
during the material transport, the air supply component keeps open to blow the foodstuff into the cleaning device; and
after the material transport is completed, the air supply component keeps open to supply the air into the cleaning device to promote movement of the foodstuff and the water.
