Description

Technical Field

[0001] The invention relates to an integrated cooker, in particular to a kitchen appliance which is a combination of a disinfection cabinet and a cooker. 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 technical solution adopted by the present invention to solve the above technical problems is: a stove-disinfection combined cooking machine, comprising a disinfection cabinet and a stove arranged above the disinfection cabinet, wherein the disinfection cabinet is provided with an ultraviolet generator, and the stove comprises a stove shell and a burner arranged on the upper end surface of the stove shell, characterized in that the cooking machine also comprises

[0012] The second air duct has an air inlet end connected to the air outlet end of the aforementioned heated pipe, and an air outlet end connected to the return air port of the inner cavity of the disinfection cabinet.

[0013] Preferably, the burner has a combustion ring with fire outlet holes formed thereon, and the heat receiving tube is arranged around the combustion ring.

[0014] Preferably, a liquid tray is provided on the upper end surface of the stove shell, the burner is located in the middle of the liquid tray, an annular concave space is formed between the lower end of the burner and the upper end surface of the liquid tray, and the heat receiving pipe is arranged in the concave space. The 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 setting of the heat receiving pipe is relatively concealed, and basically does not affect the appearance and setting of the original burner.

[0015] Compared with the prior art, the advantages of the present invention are: using the combustion heat of the stove as a high-temperature disinfection source for the disinfection cabinet; using the combustion heat of the stove as a heating and drying system; using the combustion heat of the stove to decompose ozone at high temperature; using the combustion heat of the stove to form a hot air circulation drying system, the stove and the disinfection cabinet are organically combined to achieve the purpose of compact structure and energy saving. The use of a 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. The hot and humid steam in the disinfection cabinet is discharged to prevent the tableware from getting moldy. BRIEF DESCRIPTION OF THE DRAWINGS
