[0023] In this dough mixer, the user can put flour and water into the inner pot 2 for preliminary mixing, and use the dough knife 3 at the bottom of the inner pot 2 to roll, knead, flip and squeeze the dough into a ball, thereby realizing the dough kneading function. After the flour is balled, it can be fermented in the inner pot to realize the flour fermentation function. After the set time, the steam generator 6 discharges high-temperature steam into the dough kneading chamber A to steam the dough, thereby realizing the steaming function, so that the steamed buns or bread can be automatically operated during the production process.

[0024] In this embodiment, the main body 1 includes a side leaning portion 8 arranged on the side of the inner pot 2, and the steam output pipe 7 is arranged in the side leaning portion 8, and extends into the dough kneading cavity A through the mouth of the inner pot 2 or the side wall of the inner pot 2; so that steam can be sprayed from top to bottom along the steam output pipe 7, so that the dough in the dough kneading cavity A can be evenly heated and steamed.

[0025] The inner pot 2 is detachably arranged on the main body 1, the output shaft of the driving device 4 extends out of the main body 1 and is connected to the lower connecting head 10, and the lower part of the knife shaft of the dough kneading knife 3 extends out of the inner pot 2 and is connected to the upper connecting head 11 which is transmission coupled with the lower connecting head 10; this structure enables the inner pot 2 to be disassembled from the main body 1 for easy cleaning. The inner pot 2 can be rinsed and cleaned after use to ensure the hygiene and safety of the inner pot.

[0026] The driving device 4 mainly includes a motor, and the motor is connected to the output shaft through a transmission structure such as a gear, a worm gear, and a turbine.

[0027] A water tank 12 is detachably or non-detachably connected to the main body 1, and the water tank 12 is connected to the steam generator 6 via a water supply pipe 13. The water tank 12 can automatically supply water to the steam generator 6 based on the principle of a communicating vessel, but this method places some restrictions on the relative positions of the water tank 12 and the steam generator 6.

[0028] A water pump 14 is also provided in the main body 1, and the water pumping end of the water pump 14 is connected to the water outlet of the water storage tank 12, and the water outlet end of the water pump 14 is connected to the water inlet end of the steam generator 6; the water pump 14 can automatically control the water intake of the steam generator 6, thereby controlling the steam amount, and by actively pumping water through the water pump 14, the water storage tank 12 and the steam generator 6 can be set at any height on the main body 1.

[0029] A sealing ring 18 is provided at the joint between the machine cover 17 and the inner pot 2; when in use, the machine cover 17 can be locked on the mouth of the inner pot 2 to prevent the steam pressure in the dough kneading cavity A from being too high to lift the machine cover 17, and the sealing ring 18 can seal the gap between the two, so that the dough kneading cavity A can form a relatively sealed chamber. Embodiment 2:

[0030] The difference between the second embodiment and the first embodiment is that: Figure 2 As shown, the machine cover 17 is flip-hinged on the main body 1, and the bottom surface of the machine cover 17 is provided with a steam jet outlet 9 facing downward toward the dough kneading chamber A, and the steam output pipe 7 extends into the machine cover 17 and is connected to the steam jet outlet 9, so that steam can be sprayed into the steam from top to bottom through the machine cover 17, so that the steam is evenly distributed in the dough kneading chamber A. Embodiment three:

[0031] Embodiment 3 is improved on the basis of Embodiment 1 or Embodiment 2, and is specifically as follows Figure 3 As shown, the inner pot 2 is made of a metal material, and the metal inner pot 2 can withstand pressure and high temperature. A lower heating plate 15 is arranged outside the bottom surface of the inner pot 2, and the lower heating plate 15 is electrically connected to the main control board 5. The lower heating plate 13 enables the dough mixer to fry and roast the bottom of the dough when steaming the dough, which can assist in heating and improve the steaming efficiency, and at the same time, form a rice crust layer at the bottom of the steamed bun to improve the taste.

[0032] When the inner liner 2 is detachably connected to the main body 1, the inner liner 2 is movably supported on the lower heating plate 15, and the lower heating plate 15 is arranged in the main body.
