[0033] Furthermore, terms such as "horizontal" and "vertical" do not necessarily mean that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0034] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0035] like Figure 1 and Figure 2 As shown, the steam generating device provided by the present invention includes: a water tank 1, a water pump 3, a pipeline 5, a valve body 7, a steam generator 8, a pressure-stabilizing tube 9, a water level detector 4 and a waste water tank 6.

[0036] The water tank 1 and the water pump 3 can be installed on a bracket 2, and then the bracket 2 can be fixedly connected to the top surface of the cooking cavity by screws. The water tank 1 and the water pump 3 are located at the highest position of the device.

[0037] The pipeline 5 includes a vertical pipe extending in the vertical direction and a horizontal pipe extending in the horizontal direction and arranged obliquely. The upper end of the vertical pipe forms a liquid inlet and is connected to the water pump 3. The vertical pipe can be a branch pipe or a bend pipe.

[0038] The lower end of the vertical pipe is connected to the left end of the horizontal pipe, and the right end of the horizontal pipe is connected to a spool, which is used to form a first liquid outlet, a second liquid outlet, and a third liquid outlet. The first liquid outlet of the pipeline 5 is connected to the wastewater tank 6 through the valve body 7. The second liquid outlet of the pipeline 5 is connected to the steam generator 8. In addition, the first liquid outlet is at the lowest position in the pipeline 5.

[0039] The third liquid outlet is communicated with the bottom opening of the pressure-stabilizing tube 9, the top opening of the pressure-stabilizing tube 9 is communicated with the cooking cavity through the exhaust elbow 10, and the pressure-stabilizing tube 9 is provided with a steam interface located between the top opening and the bottom opening, and the steam interface is connected to the steam outlet of the steam generator 8. The steam generated by the steam generator 8 first enters the pressure-stabilizing tube 9 and then enters the cooking cavity, the pressure-stabilizing tube 9.

[0040] In the four-way valve, the first liquid outlet is located directly below the third liquid outlet, so that the water in the pressure-stabilizing tube 9 can quickly flow into the wastewater tank 6.

[0041] The water level detector 4 is connected to the transverse pipe and is used to detect the water level of the steam generator 8. In addition, the water level detector 4, valve body 7 (e.g., solenoid valve), water pump 3, and steam generator 8 are all connected to the controller of the cooking device. When the water pump 3 is pumping water and the water level detector 4 reaches a threshold water level, the controller receives a water level signal and stops pumping water.

[0042] In order to achieve a reasonable spatial arrangement, the water level detector 4, the voltage regulator tube 9 and the steam generator 8 are all connected to the back of the cooking cavity. The waste water tank 6 is located below the cooking cavity, which is convenient for taking out the waste water tank 6 or draining the sewage in the waste water tank 6.

[0043] The wastewater tank 6 and valve body 7 are detachable. For example, a first connector that disconnects when removed can be provided inside the wastewater tank 6, and a second connector corresponding to the first connector can be provided on the valve body 7. The second connector is inserted into the first connector, providing continuity, and the first connector disconnects when the second connector is removed. This type of first and second connectors, which prevent disconnection, are known in the art. This solution utilizes these first and second connectors to facilitate removal of the wastewater tank 6 and cleaning of the interior of the wastewater tank 6.

[0044] The water tank 1 is filled with water, and the steaming function is turned on. The water pump 3 pumps the water in the water tank 1 into the pipe 5, and the steam generator 8 works. When the water level reaches the threshold water level of the water level detector 4, the controller obtains the water level signal and stops pumping water. The steam generator 8 heats the water in the pipe 5, vaporizes it, and discharges it through the exhaust port connected to the cavity. The voltage regulator tube 9 is used to stabilize the air pressure (water vaporizes, the volume expands, and the air pressure rises) and recover some steam. When the work is completed, the controller controls the valve body 7 to work, and the water in the pipe 5 is discharged from the valve body 7 into the waste water tank 6 to prevent scale, prevent the water in the pipe 5 from contaminating the water in the water tank 1, prevent the water in the pipe 5 from deteriorating, and prevent the hot water pumped back from the pipe 5 from scalding the user.

[0045] The cooking device provided by the present invention includes the above-mentioned steam generating device. Since the cooking device provided by the present invention uses the above-mentioned steam generating device, the cooking device provided by the present invention also has the advantages of the steam generating device.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
