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.

[0008] The third technical problem to be solved by the present invention is to provide a control method for a stove-disinfection combination cooking machine that 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.

[0010] A first heat receiving tube is arranged around the outer ring fire cover;

[0011] A second heat receiving tube is arranged around the central fire cover and arranged in parallel with the first heat receiving tube;

[0012] A first air duct, the air outlet of which is respectively connected to the air inlet of the first heat receiving pipe and the second heat receiving pipe;

[0013] A fan, the air inlet port of which is connected to the inner cavity of the disinfection cabinet, the air outlet end of which is provided with a reversing valve and leads to the exhaust passage on one side and is connected to the air inlet end of the aforementioned first air duct on the other side; and

[0014] The second air duct has an air inlet end connected to the air outlet ends of the first heated pipe and the second heated pipe respectively, and an air outlet end connected to the return air port of the inner cavity of the disinfection cabinet.

[0015] Furthermore, the first heat receiving pipe is provided with an opening and closing valve, and the opening and closing valve is closed when the outer ring fire cover is not burning.

[0016] Furthermore, the cooking machine also includes a controller. An angle sensor capable of sensing the rotation angle of the knob is provided in the stove shell near the knob. The signal output end of the angle sensor is connected to the controller. The fan, reversing valve and opening and closing valve are controlled by the controller.

[0017] The technical solution adopted by the present invention to solve the third technical problem is: a control method of a stove-and-diesel combined cooking machine, comprising the following steps:

[0018] If the angle sensor detects that the knob is in the state of opening the center fire cover, the controller issues a command, the opening and closing valve is closed, the fan is started, and the first air duct, the second air duct and the second heated pipe form a circulating air duct to dry the inner cavity of the disinfection cabinet and decompose ozone;

[0019] If the angle sensor detects that the knob is in the state of opening the center fire cover and the outer ring fire cover at the same time, the controller sends a command, the opening and closing valve opens, and the fan is started. The first air duct, the second air duct, the first heated tube and the second heated tube form a circulating air duct to dry the inner cavity of the disinfection cabinet and decompose ozone.

[0020] Compared with the prior art, the advantages of the present invention are: using the heat generated by the combustion of the stove as the high-temperature disinfection source of the disinfection cabinet, the heating source of the drying system and the high-temperature decomposition ozone heating source; cooperating with the fan to form a hot air circulation, the stove and the disinfection cabinet are organically combined to achieve the purpose of compact structure and energy saving. The use of the fan to realize the circulation of high-temperature airflow is conducive to shortening the ozone decomposition time and reducing the ozone content in the disinfection cabinet. At the same time, the circulating high-temperature airflow is also conducive to drying tableware in a short time, and the temperature rise in the disinfection cabinet is also relatively uniform. Exhaust the hot and humid steam in the disinfection cabinet to prevent the tableware from getting moldy. BRIEF DESCRIPTION OF THE DRAWINGS
