Abstract

Disclosed is an automatic stir-fryer comprising: a machine stand; a base pivotably provided on the machine stand; a rotary shaft providing rotary power and connected to a stir-frying rotary tank containing foodstuffs; a high-frequency induction heating unit coaxially covering the stir-frying rotary tank; a tilting unit pivotably disposed on the base; a receiving tank provided on the machine stand for receiving the cooked foodstuffs and controlled by an automatic push rod to move forward and backward; a cleaning unit assembled on the machine stand and corresponding to the stir-frying rotary tank after tilting by the tilting unit for water cleaning the stir-frying rotary tank; a control unit vertically disposed on the machine stand and provided with an control panel for controlling the operating time of the automatic stir-fryer and the temperature of the high-frequency induction heating unit.

Claims

1. An automatic stir-fryer, comprising:

a machine stand having two lateral sides;

a base pivotably disposed on the machine stand, wherein a dynamic power source having a rotary shaft is disposed on the base and the rotary shaft is connected with a stir-frying rotary tank containing foodstuffs;

a high-frequency induction heating unit coaxially covering the stir-frying rotary tank;

a tilting unit disposed on the base for driving and pivoting the base to turn over and to return back to an original position;

a receiving tank disposed on the machine stand for receiving the foodstuffs dumped out from the stir-frying rotary tank and controlled by an automatic push rod to move forward and backward, wherein the receiving tank is capable of being drew out from and stored in the machine stand automatically by the automatic push rod;

a cleaning unit disposed on the machine stand and situated in correspondence to the stir-frying rotary tank after being turned over for cleaning the stir-frying rotary tank;

a drying unit disposed on the machine stand and comprising a funnel-shape tank; and

a control unit disposed on the machine stand and having a control panel for controlling an action period and a temperature for the automatic stir-fryer.

2. The automatic stir-fryer as claimed in claim 1, wherein the control unit further comprises a temperature transceiver for detecting a heating temperature for the stir-frying rotary tank.

3. The automatic stir-fryer as claimed in claim 1, wherein the tilting unit further comprises an actuator disposed at one of the two later sides of the machine stand, which actuator has a driving rod with a power output end, which power output end is pivotably connected with the base, so as to drive the base to turn over or to return back to the original position.

4. The automatic stir-fryer as claimed in claim 3, wherein the actuator is selected from one of a hydraulic cylinder and a screw linear actuator.

5. The automatic stir-fryer as claimed in claim 1, wherein the cleaning unit further comprises a water hose and an air hose for cleaning the stir-frying rotary tank.

6. The automatic stir-fryer as claimed in claim 2, wherein the cleaning unit further comprises a water hose and an air hose for cleaning the stir-frying rotary tank.

7. The automatic stir-fryer as claimed in claim 1, wherein the high-frequency induction heating unit includes a circular frame and one pair of coils, the circular frame coaxially covers the stir-frying rotary tank, and the pair of the coils is arranged at two opposite sides of the circular frame respectively and electrically connected with the control unit.

8. The automatic stir-fryer as claimed in claim 5, wherein the high-frequency induction heating unit includes a circular frame and one pair of coils, the circular frame coaxially covers the stir-frying rotary tank, and the pair of the coils is arranged at two opposite sides of the circular frame respectively and electrically connected with a control unit.

9. The automatic stir-fryer as claimed in claim 1, wherein the drying unit further comprises a set of slide tracks disposed in the machine stand and situated under the receiving tank, a drawer recycling tank sliding on the set of slide tracks, which drawer recycling tank has a bottom opened with multiple apertures, and the funnel-shape tank disposed under the drawer recycling tank, for draining out the wasted water.

10. The automatic stir-fryer as claimed in claim 2, wherein the drying unit further comprises a set of slide tracks disposed in the machine stand and situated under the receiving tank, a drawer recycling tank sliding on the set of slide tracks, which drawer recycling tank has a bottom opened with multiple apertures, and the funnel-shape tank disposed under the drawer recycling tank, for draining out the wasted water.

11. The automatic stir-fryer as claimed in claim 3, wherein the drying unit further comprises a set of slide tracks disposed in the machine stand and situated under the receiving tank, a drawer recycling tank sliding on the set of slide tracks, which drawer recycling tank has a bottom opened with multiple apertures, and the funnel-shape tank disposed under the drawer recycling tank, for draining out the wasted water.

12. The automatic stir-fryer as claimed in claim 7, wherein the drying unit further comprises a set of slide tracks disposed in the machine stand and situated under the receiving tank, a drawer recycling tank sliding on the set of slide tracks, which drawer recycling tank has a bottom opened with multiple apertures, and the funnel-shape tank disposed under the drawer recycling tank, for draining out the wasted water.

13. The automatic stir-fryer as claimed in claim 1, further comprising a looped guiding plate disposed under the water hose.

14. The automatic stir-fryer as claimed in claim 1, further comprising a sensor disposed in correspondence to the receiving tank, wherein the sensor is electrically connected with the control unit for detecting whether a drew-out state or a stored-in state the receiving tank is currently to be placed in.
