[0023] The cover 2 used in this dough mixer is provided with a cover flange 201, which supports the cover 2 and can improve the strength of the bottom of the cover 2 to prevent the cover 2 from being deformed by being squeezed. The cover 2 is supported by the cover flange 201, so that a gap is left between the bottom surface of the cover flange 201 and the steam generating device 3. Even if the steam generating device 3 is not installed flat during assembly, the cover 2 will not be lifted up to affect the sealing. In addition, the condensed water formed on the inner wall of the cover 2 can directly flow back to the steam generating device 3 for reheating and use, and will not accumulate in the gap between the cover 2 and the base 1 to cause the condensed water to overflow due to excessive filling. The joint between the cover 2 and the base 1 is transitioned through the cooperation of the cover flange 201 and the supporting flange 301, making the appearance of the dough mixer more concise and beautiful.

[0024] The steam generating device 3 comprises a bottom cover 31, which is a bowl-shaped structure and is made of metal material in one piece, and a water storage tank is defined inside the bottom cover 31. A heating plate 32 is assembled and connected to the bottom of the bottom cover 31. The cover 2 is arranged on the top of the bottom cover 31 and a steam chamber 204 is defined therebetween. When in use, a certain amount of clean water is poured into the water storage tank, and the heating plate 32 heats the clean water in the water storage tank, so that the steam chamber 204 generates high-temperature steam, and the steam fills the steam chamber 204, and then the steam rises into the inner pot to heat and steam the dough, so that the dough mixer also has the function of steaming dough.

[0025] In order to ensure the safe use of the dough mixer, a pressure relief port connected to the steam chamber 204 is provided on the cover 2. When the pressure in the steam chamber 204 is too high, the steam can be discharged through the pressure relief port.

[0026] An annular sealing groove 302 is provided on the inner side of the supporting flange 301, and a bent flange 311 is provided on the edge of the bottom cover 31. The bent flange 311 is buckled on the sealing groove 302. The bottom surface of the cover 2 is tightly attached to the top of the bent flange 311, and the inner wall of the cover and the inner wall of the bottom cover are smoothly transitioned, so that when the condensed water on the inner wall of the cover 2 flows to the bottom, it can flow into the water storage tank of the bottom cover 31.

[0027] A sealing ring 4 is embedded in the sealing groove 302, and the sealing ring 4 is crimped between the cover wall of the cover 2 and the supporting flange 301, and the bent flange 311 is crimped on the sealing ring 4; the sealing ring 4 can seal the gap between the base 1 and the cover 2, so that a relatively sealed steam chamber 204 is formed in the cover 2. In addition, a pressure relief port 205 connected to the steam chamber 204 is also opened on the top of the cover 2 to avoid excessive pressure in the steam chamber 204.

[0028] The sealing ring 4 includes a sealing body 41, and a lower sealing portion 42 adapted to the width of the sealing groove 302 is arranged at the bottom end of the sealing body 41; the bent flange 311 is crimped on the lower sealing portion 42; the top of the sealing body 41 is provided with an elastic sealing lip 43 abutting against the outer wall surface of the cover wall, and the cover 2 is provided on the upper and lower sealing portions 42 of the base 1 through the elastic sealing lip 43 interference cover to seal the assembly gap between the bottom cover 31 and the shell 11, and the elastic sealing lip 43 enables the cover 2 to be tightly fitted during assembly, thereby improving the sealing performance.

[0029] A first slipstream arc surface 202 is provided at the joint between the cover flange 201 and the cover wall of the cover 2, and a second slipstream arc surface 203 connected to the first slipstream arc surface 202 is provided on the outer side of the cover flange 201; the outer end surface of the cover flange 201 smoothly transitions with the outer end surface of the supporting flange 301.
