Description

Technical Field

[0001] The present invention relates to an integrated cooker, and in particular to a cooking machine combining a disinfection cabinet and a cooker. The present invention also relates to a control method of the cooking machine. Background Art

[0002] Combination is the future development direction of cooking equipment. Combined cooking equipment has the advantages of occupying less kitchen space and being easy to use. Existing combined cooking machines generally combine a stove with a steamer or oven or dishwasher or disinfection cabinet. Among them, a combined cooking machine that generally integrates a stove and a disinfection cabinet is called a stove-disinfection combined cooking machine. For example, the utility model patent "An Integrated Stove" with patent number ZL201220717647.2 (authorization announcement number CN203073720U) discloses an integrated stove, including a base, a disinfection cabinet arranged above the base, and a stove located above the disinfection cabinet.

[0003] At present, the disinfection cabinet module and the stove module in the stove disinfection cooking machine are connected together through the communication interface, and the disinfection cabinet function and the stove function operate independently. The flame temperature of the stove is as high as about 1000 degrees, and the temperature near the combustion chamber on the surface of the stove is also about 300 degrees. The disinfection cabinet adopts a disinfection method combining ultraviolet rays, ozone and temperature. Ozone is produced by ultraviolet irradiation of ultraviolet lamps (185nm band ultraviolet rays ionize and recombine oxygen molecules to generate ozone).

[0004] Ozone is a combination of highly activated oxygen atoms and oxygen molecules. It has active chemical properties, unique molecular structure and spectral absorption characteristics, and is easily decomposed. At room temperature, the natural decomposition rate is slow; the decomposition is accelerated in a hot and humid environment; when the temperature exceeds 100°C, the decomposition is violent, and at around 270°C, ozone will immediately decompose into oxygen.

[0005] After the ozone disinfection process is completed, a large amount of ozone remains in the disinfection cabinet. At present, disinfection cabinet products decompose ozone by temperature while drying tableware. Since the heat is generated by electric heating components in the disinfection cabinet and there is a lack of a circulation system, the heat increases the temperature in the disinfection cabinet through a natural diffusion process; this causes the temperature in the disinfection cabinet to rise slowly, the temperature is uneven, the tableware drying time is long, the ozone decomposition is slow, and it takes a long time to meet the ozone leakage standard. Summary of the invention

[0006] The first technical problem to be solved by the present invention is to provide a stove-disinfection combined cooking machine which utilizes the residual heat of the stove to provide a heat source for the disinfection cabinet in response to the above-mentioned technical status quo.

[0007] The second technical problem to be solved by the present invention is to provide a stove-disinfectant combined cooking machine with fast ozone decomposition and uniform heating of the inner cavity of the disinfection cabinet in response to the above-mentioned technical status quo.

The first heat receiving pipe is in close contact with the burner, can be heated quickly, and fully utilizes the waste heat of the burner. At the same time, the arrangement of the heat receiving pipe is relatively concealed, and basically does not affect the appearance and arrangement of the original burner.

[0020] Furthermore, the cooking machine also includes a controller, the fan and the valve are controlled by the controller, the stove shell is provided with a first thermocouple and a second thermocouple near the first burner and the second burner respectively, and the signal output ends of the first thermocouple and the second thermocouple are connected to the controller.

[0053] Second type:

[0054] If the rotation angle of the first knob 241 is greater than the rotation angle of the second knob 242, the controller 100 issues a command, and the valve 4 adjusts the flow rate of the first air inlet duct 51 to be greater than the flow rate of the second air inlet duct 55;
