[0028] Embodiment 2

[0029] The solution in the first embodiment is further introduced below in combination with a specific working method, as described below for details:

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the water tank 4 is detachably connected to the device housing 1 through the mounting plate 2 and the fixing bolts 3, and the first heating tube 5 is fixedly connected to the water tank 4. By unscrewing the fixing bolts 3 on the mounting plate 2, the water tank 4 can be disassembled, which is convenient for subsequent maintenance of the device. The first heating tube 5 arranged in the water tank 4 is started to heat the clean water in the water tank 4, so that the clean water generates steam to humidify the steam oven; the depth of the exhaust port 7 is equal to the thickness of the water tank 4, and the water inlet 9 is connected to the water tank 4 through the connecting pipe 8. The fixed cover 10 and the water inlet 9 are movably connected, and steam is continuously generated, so that the steam is discharged through the exhaust port 7 on one side of the baffle 6, so that the heated air is blown downward, and the steam is blown onto the food, thereby humidifying the food, ensuring the moisture content of the food, and ensuring the nutrients of the food, thereby improving the practicality of the device.

[0031] like Figure 1 , Figure 2 and Figure 4As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the installation cavity 11 is arranged at the upper end of the device housing 1, and a fixing ring 12 is arranged inside the installation cavity 11, and a filter screen plate 13 is arranged above the fixing ring 12. Four fixing screws 14 are symmetrically arranged on the upper surface of the filter screen plate 13. The filter screen plate 13 is detachably connected to the device housing 1 through the installation cavity 11, the fixing ring 12, and the fixing screws 14. A fixing plate 15 is arranged on the inner wall of the device housing 1, and the fixing plate 15 is fixedly connected to the device housing 1. When the air intake fan 16 is started, the external air is drawn in through the filter screen plate 13, and the second heating tube 17 is started to draw in the air. The air passes through the steam oven and is heated, and then is discharged into the steam oven through the exhaust port to bake the food inside the steam oven; the air intake fan 16 is symmetrically installed inside the fixing plate 15, and the air intake fan 16 and the fixing plate 15 are an integrated fixed structure.

When it is necessary to humidify the inside of the steam oven, the first heating tube 5 set in the water storage tank 4 is started to heat the clean water in the water storage tank 4 so that the clean water generates steam. By continuously generating steam, the steam is discharged to the bottom of the exhaust grille 18 through the exhaust port 7 on one side of the baffle 6, so that the heated air is blown downward to blow the steam. The water supply 9 is set on the connecting pipe 8, and the fixing cover 10 is removed to add clean water to the water storage tank 4. A scale is set on the connecting pipe 8. When the added clean water exceeds the scale, the water addition should be stopped to avoid leakage due to excessive clean water in the water storage tank 4. The fixing screws 14 on the filter screen plate 13 are unscrewed to separate the fixing screws 14 and the fixing ring 12, and the fixing of the filter screen plate 13 is released. In this way, the filter screen plate 13 can be taken out from the installation cavity 11, which is convenient for cleaning the filter screen plate 13. The water storage tank 4 can be disassembled by unscrewing the fixing bolts 3 on the mounting plate 2, which is convenient for subsequent maintenance of the device.

[0035] Through the above configuration, the present application can certainly solve the above technical problems and achieve the following technical effects:

[0036] The utility model can disassemble the water storage tank 4 by unscrewing the fixing bolts 3 on the mounting plate 2, so as to facilitate the subsequent maintenance of the device. The first heating tube 5 arranged in the water storage tank 4 is started to heat the clean water in the water storage tank 4, so that the clean water generates steam to humidify the steam oven; by continuously generating steam, the steam is discharged through the exhaust port 7 on one side of the baffle plate 6, so that the heated air is blown downward, and the steam is blown onto the food, so as to humidify the food, ensure the moisture content of the food, and ensure the nutrients of the food, thereby improving the practicality of the device;
