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.

[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 temperature detected by the thermocouple is not higher than the set temperature, the controller issues a command to start the heater for drying the disinfection cabinet and decomposing ozone;

The first air duct, the second air duct and the heated ring form a circulating air duct to dry the inner cavity of the disinfection cabinet and decompose ozone.

[0020] Furthermore, there are two burners, and each burner is correspondingly provided with a pot support, a first air duct and a second air duct, and the fan is connected to the two first air ducts respectively.

[0021] The following steps are also included:

[0029] The present invention is further described in detail below with reference to the accompanying drawings.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the stove-disinfection combination cooking machine in this embodiment includes a disinfection cabinet 1, a stove 2 arranged above the disinfection cabinet 1, a first air duct 51, a fan 3 and a second air duct 52.

[0031] Combination Figure 5 As shown, the disinfection cabinet 1 is provided with a controller 100, a drawer 11, an ultraviolet generator 12 and a heater 13. The stove 2 is a double-eye stove, including a stove shell 21 and a burner 23 and a pot support 22 arranged on the upper end surface of the stove shell 21.

[0032] The pot support 22 includes a base 221 , legs 222 and a heat ring 223 . The legs 222 are multiple and evenly distributed on the base 221 . The heat ring 223 is connected to the upper ends of the legs 222 . The heat ring 223 is arranged around the burner 23 .

[0033] The first air duct 51 is arranged at the air inlet end of the heated ring 223; the air inlet port of the fan 3 is connected to the inner cavity of the disinfection cabinet 1, and the air outlet end is provided with a switching valve 4 and leads to the exhaust channel 54 on one path, and is connected to the air inlet end of the first air duct 51 on the other path; the air inlet end of the second air duct 52 is connected to the air outlet end of the heated ring 223, and the air outlet end is connected to the return air port 53 of the inner cavity of the disinfection cabinet 1.

[0034] There are two burners 23 , and each burner 23 is correspondingly provided with a pot support 22 , a first air duct 51 and a second air duct 52 , and the fan 3 is connected to the two first air ducts 51 respectively.

[0035] Combination Figure 5 As shown, the control end of the controller 100 is connected to the fan 3, the heater 13, and the switching valve 4 respectively, and a thermocouple 24 is provided on the upper end surface of the stove shell 21 near the burner 23, and the signal output end of the thermocouple 24 is connected to the controller 100.

[0036] The control method of the stove-and-diesel combined cooking machine comprises the following steps:

[0037] If the temperature detected by the two thermocouples 24 is not higher than the set temperature, it means that the burner is not working, and the controller 100 issues a command to start the heater 13 for drying and decomposing ozone in the disinfection cabinet 1;

[0038] If the temperature detected by the two thermocouples 24 is higher than the set temperature, it means that the burner is in working state, the heater 13 is turned off, the fan 3 is started, and the first air duct 51, the second air duct 52 and the heated ring 223 form a circulating air duct to dry the inner cavity of the disinfection cabinet 1 and decompose ozone.

[0039] If the temperature of one of the thermocouples 24 is not higher than the set temperature, and the other one is higher than the set temperature, it means that one of the burners is in working state, then the heater 13 is turned off, and the fan 3 is started. The heated ring 223 corresponding to the temperature higher than the set temperature forms a circulating air duct with the corresponding first air duct 51 and second air duct 52 to dry the inner cavity of the disinfection cabinet 1 and decompose ozone.

[0040] The working status is as follows:

[0041] Drying process: The fan is turned on, and the air in the disinfection cabinet enters the heating ring through the first air duct. The air in the heating ring is heated and then enters the disinfection cabinet through the second air duct. The air in the disinfection cabinet is circulated to the vicinity of the burner through the fan, and the gas temperature rises. The high-temperature gas circulates into the disinfection cabinet to circulate and dry the tableware, thereby improving the disinfection and drying effects of the tableware.

[0042] After the disinfection is completed: the fan is turned on, and the air in the disinfection cabinet cavity enters the heating ring through the first air duct. After the air in the heating ring is heated, it enters the disinfection cabinet cavity through the second air duct. After the disinfection is completed, the ozone-containing air in the disinfection cabinet is circulated to the vicinity of the burner through the fan. The temperature near the burner is high, and the ozone in it is quickly decomposed into oxygen. At the same time, the gas temperature rises, and the high-temperature gas is circulated to the disinfection cabinet for circulating and drying tableware, improving the disinfection and drying effects of the tableware.

[0043] Exhaust process: After the disinfection process or drying process is completed, the ozone decomposition is completed, the switching valve is switched to the exhaust mode, and the fan exhausts the hot and humid steam in the disinfection cabinet to the exhaust duct. The exhaust duct here can be built-in to the cooking machine or externally connected after installation.
