[0031] The present invention will be further described below with reference to the accompanying drawings and examples. Example 1

[0032] like Figure 1 and Figure 2 As shown, a dough mixing machine with steaming function, comprising: Base 1, the base 1 is provided with a drive device 4 and a control system 5, the drive device 4 is electrically connected to the control system 5, the output end of the drive device 4 is provided with an output shaft 41; The outer pot 2 is placed on the base 1 and defines a steam chamber 201 therein. A steam generating structure is provided at the bottom of the outer pot 2 for generating steam in the steam chamber 201. The output shaft 41 of the driving device 4 extends into the steam chamber 201 and is connected to a lower connector 6. The inner liner 3 is detachably embedded in the steam chamber 201, and an inner liner anti-rotation assembly 7 is provided between the inner liner 3 and the outer pot 2, and a steam inlet structure connecting the steam chamber 201 and the inner cavity of the inner liner 3 is provided on the inner liner 3. The bottom of the inner liner 3 is rotatably connected to a knife shaft 8, the lower part of the knife shaft 8 extends into the steam chamber 201 and is connected to an upper connector 9 that is transmission coupled with the lower connector 6, and the upper part of the knife shaft 8 extends into the inner cavity of the inner liner 3 and is connected to a dough knife 10.

[0033] In this dough mixer, the user can put flour and water into the inner container for preliminary mixing, and use the dough knife 10 at the bottom of the inner container 3 to roll, knead, flip and squeeze the dough into a ball, thereby realizing the dough kneading function. After the flour is formed into a ball, it can be fermented in the inner container 3, thereby realizing the flour fermentation function. After the set time, the steam generating structure generates high-temperature steam in the steam chamber 201 to steam the dough, thereby realizing the steaming function, so that the steamed bun making process can be automated. In addition, the most basic inner pot 3 in the noodle mixer can be disassembled from the outer pot 2, which is convenient for users to take out flour or steamed buns. After use, the inner pot 3 can be rinsed and cleaned to ensure that the inner pot 3 is clean and hygienic. In addition, the inner pot 3, or the outer pot 2 together with the inner pot 3 can be disassembled, so that the noodle mixer can use the steam generating structure to meet different cooking needs, thereby improving the practicality of the noodle mixer and improving its market competitiveness.

[0034] The base 1 includes a shell 101 and a bottom cover 21 fixedly assembled on the shell 101. The mouth of the bottom cover 21 is detachably covered with a cover 22. The cover 22 is provided with a pressure relief port 221 connected to the steam chamber 201. A sealing member 23 is provided between the cover 22 and the bottom cover 21, and the cover 22 and the bottom cover 21 together form an outer pot 2 through the sealing member 23.

[0035] The bottom cover 21 is a bowl-shaped structure made of metal material, and defines a water storage tank inside. The bottom of the metal bottom cover 21 is assembled and connected with a heating plate 24. The heating plate 24 and the metal bottom cover 21 together constitute a steam generating structure.

[0036] In the above embodiment, when in use, a certain amount of clean water is poured into the water storage tank, the cover 22 is placed on the outer periphery of the inner pot 3, and then the heating plate 24 works, and the clean water is heated to boiling through the metal bottom cover 21 and high-temperature steam is generated to fill the steam cavity, and then the steam rises into the inner pot to heat and steam the dough.

[0037] In addition, if Figure 3 As shown, in actual use, the inner pot 3 can be removed from the base 1, and one or more steamers 17 or steaming grids can be placed above the bottom cover 21, and then the cover 22 is covered on the periphery of the steamer 17 or the steaming grid. Alternatively, the cover 22 and the inner pot 3 can be removed from the base 1, and the steamer on the top layer uses the corresponding steamer cover 18, so that the steamer or steaming grid is not limited to the height of the cover 22. The steam generating structure is used to heat and generate steam to steam the food in the steamer or steaming grid, so that the base 1 is linearly transformed into an electric steamer structure, thereby improving the functionality and practicality of the noodle mixer.

[0038] like Figure 4 As shown, the base 1 is provided with a circle of supporting flanges 102 along the outer periphery of the bottom cover 21. The cover wall of the cover cover 22 is embedded inside the supporting flange 102, and a cover flange 221 extends outward from the bottom of the cover wall and abuts against the supporting flange 102. The cover flange 221 abuts against the supporting flange 102, so that the bottom surface of the cover cover 22 is tightly attached to the edge of the bottom cover 21.

[0039] The cover 22 used in this dough mixer has a cover flange 221 added to it. This flange 221 supports the cover 22, increasing the strength of the bottom of the cover 22 and preventing deformation caused by compression. Furthermore, the cover 22 is supported by the flange 221, leaving a gap between the bottom surface of the flange 221 and the bottom cover 21. Even if the bottom cover 21 is not installed flat during assembly, the flange 221 will not lift up the cover 22 and affect the sealing performance. In addition, the condensed water formed on the inner wall of the cover 22 can directly flow back into the bottom cover 21 for reheating and use, and will not accumulate in the gap between the cover 22 and the base 1 to cause the condensed water to overflow. The joint between the cover 22 and the base 1 is transitioned through the cover flange 221 and the support flange 102, making the appearance of the dough mixer more simple and beautiful.

[0040] An annular sealing groove 103 is provided on the inner side of the supporting flange 102, and a bent flange 211 is provided on the edge of the bottom cover 21. The bent flange 211 is buckled on the sealing groove 103, and the bottom surface of the cover 22 is tightly attached to the top of the bent flange 211, and the inner wall of the cover 22 and the inner wall of the bottom cover 21 are smoothly transitioned, so that when the condensed water on the inner wall of the cover 22 flows to the bottom, it can flow into the water storage tank of the bottom cover 21.

[0041] A seal 23 is embedded in the sealing groove 103, and the seal 23 is crimped between the cover wall of the cover 22 and the supporting flange 102, and the bent flange 211 is crimped on the seal 23; the seal 23 can seal the gap between the base 1 and the cover 22, so that a relatively sealed steam chamber 201 is formed in the cover 22.

[0042] The sealing member 23 includes a sealing body 231, the bottom end of which is provided with a lower sealing portion 232 adapted to the width of the sealing groove 103; the bent flange 211 is crimped on the lower sealing portion 232; the top end of the sealing body 231 is provided with an elastic sealing lip 233 that is abutted against the outer wall of the cover wall, and the cover 22 is provided with an elastic sealing lip 233 that interferes with the upper and lower sealing portions 232 of the base 1 to seal the assembly gap between the bottom cover 21 and the shell, and the elastic sealing lip 233 enables the cover 22 to be tightly fitted during assembly, thereby improving the sealing performance.

[0043] A first slipstream arc surface 222 is provided at the joint between the cover flange 221 and the cover wall of the cover 22, and a second slipstream arc surface 223 connected to the first slipstream arc surface 222 is provided on the outer side of the cover flange 221; the outer end surface of the cover flange 221 smoothly transitions to the outer end surface of the support flange 102.

[0044] A trumpet-shaped shell neck 104 is provided at the top of the shell, and the top end of the shell neck 104 constitutes a supporting flange 102. The inner wall of the shell neck 104 is provided with a lap edge 105, and a sealing groove 103 is formed between the lap edge 105 and the supporting flange 102. The lap edge 105 surrounds an assembly opening, and the bottom cover 21 is connected to the assembly opening.

[0045] When condensed water or liquid drips onto the outer surface of the cover 22 through the first slipstream arc surface 222, the second slipstream arc surface 223 and the trumpet-shaped shell neck 104, the potential energy of the condensed water or liquid can be increased, so that the condensed water or liquid quickly flows through the concave and convex surfaces between the cover 22 and the base 1, and slides out of the base 1 on the shell of the base 1, avoiding the accumulation of condensed water or liquid at the junction between the two, so that the dough mixer remains clean during use.

[0046] In other embodiments, different from the first embodiment, the steam generating structure is not composed of the heating plate 24 and the metal bottom cover 21, but includes a steam generator 11. The steam generator 11 is provided with a steam pipe 12 connected to the bottom cover 21. The steam generating chamber of the steam generator 11 is connected to the steam chamber 201 through the steam pipe 12. The steam is generated by the independent steam generator 11 and transported to the steam chamber 201. And on this structure, as Figure 5As shown, the steam generating structure further includes a water tank 13, which is detachably or non-detachably connected to the base 1. The water tank 13 is connected to the steam generator 11 via a water supply pipe 14. The water tank 13 can automatically supply water to the steam generator 11 through the water tank 13 using the communicating vessel principle, but this method has some restrictions on the relative position of the water tank 13 and the steam generator 11. Alternatively, the steam generating structure may be further improved on the basis of the water tank 13. Specifically, the steam generating structure may further include a water pump 15, the water pumping end of the water pump 15 being connected to the water tank 13, and the water outlet end of the water pump 15 being connected to the steam generator 11. The water intake of the steam generator 11 may be automatically controlled by the water pump 15, thereby controlling the steam volume. Furthermore, the water tank 13 and the steam generator 11 may be arbitrarily arranged on the base 1 by actively pumping water through the water pump 15.

[0047] In this embodiment, the steam inlet structure is actually the inner pot opening 301. An air inlet gap is provided between the edge of the inner pot 3 and the outer pot 2. The inner cavity of the inner pot 3 is connected to the steam cavity 201 through the air inlet gap and the inner pot opening 301. In more embodiments, the steam inlet structure also includes a plurality of air inlets opened on the side wall of the inner liner 3, and the inner cavity of the inner liner 3 is connected to the steam chamber 201 through the plurality of air inlets; however, opening the air inlets on the side wall of the inner liner 3 may affect the maximum capacity of the inner liner, so this structure is not used as a preferred embodiment and will not be elaborated or marked in detail here and in the accompanying drawings.

[0048] like Figures 6 to 10 As shown, the inner tank anti-rotation assembly 7 includes a supporting cylinder 71 and a connecting cylinder 72, and the supporting cylinder 71 and the connecting cylinder 72 are nested with each other; The support cylinder 71 is fixed to the center of the bottom of the outer pot 2, and the lower connector 6 is placed in the support cylinder 71. The support cylinder 71 is provided with a plurality of rotating connectors along the circumference. The inner pot 3 is supported on the support cylinder 71 and forms a water boiling space between the inner pot 3 and the bottom of the outer pot 2. The connecting cylinder 72 is fixed to the outside of the bottom of the inner pot 3, the upper connecting head 9 is placed in the connecting cylinder 72, and a plurality of screw-on fittings are circumferentially arranged on the connecting cylinder 72 corresponding to the rotating connecting piece. The outer pot 2 cooperates with the screw-on fittings through the rotating connecting piece to limit the axial rotation of the inner pot 3 relative to the outer pot 2.

[0049] This dough mixer can lock the inner pot 3 when the dough knife 10 rotates through the cooperation of the supporting cylinder 71 and the connecting cylinder 72, limiting the inner pot 3 from rotating axially along the knife shaft, and the supporting cylinder 71 props up the inner pot 3 to a certain height. On the one hand, there is enough space between the upper connecting head 9 and the lower connecting head 6 for coupling, which reduces the difficulty of production and assembly. On the other hand, there is more space between the inner pot 3 and the bottom of the outer pot to store more drinking water, and high-temperature steam can be generated for a long time during heating, so that the dough mixer can steam food for a longer time.

[0050] Specifically, the rotating connecting part includes a plurality of rotating buckling blocks 73, and the plurality of rotating buckling blocks 73 are evenly distributed on the top of the inner wall of the supporting cylinder 71; the rotating fitting part includes a plurality of rotating buckling grooves 74 in the shape of an inverted L, and the plurality of rotating buckling grooves 74 are evenly distributed on the outer wall surface of the connecting cylinder 72. The supporting cylinder 71 and the connecting cylinder 72 are buckled and connected by cooperating with the rotating buckling blocks 73 and the rotating buckling grooves 74.

[0051] The rotating buckle groove 74 includes an axially extending buckle section 741 and a longitudinally extending entrance section 742, and the width of the entrance section 742 gradually decreases from the entrance end toward the buckle section 741; the entrance section 742 of this structure makes it easier to introduce the rotating buckle block 73 into the rotating buckle groove 74, thereby improving assembly efficiency.

[0052] A connecting base plate 75 is further provided on the upper portion of the connecting cylinder 72, and a sealing sleeve 19 is provided on the edge of the connecting base plate 75. The connecting cylinder 72 is fastened to the bottom surface of the inner tank 3 through the connecting base plate 75. At least the lower portion of the connecting cylinder 72 is in the shape of a truncated cone with a wide upper portion and a narrow lower portion. The connecting cylinder 72 with this structure makes it easier to insert the connecting cylinder 72 into the supporting cylinder 71, thereby improving assembly efficiency.

[0053] The sealing sleeve 19 is provided with an upper sealing surface 191 and a lower sealing surface 192. The upper sealing surface 191 is pressed between the connecting bottom plate 75 and the bottom surface of the inner liner 3, and the lower sealing surface 192 is pressed between the connecting bottom plate 75 and the supporting cylinder 71. In addition, the bottom surface of the connecting bottom plate 75 is provided with an avoidance groove 751 corresponding to the top edge of the supporting cylinder 71. After the connecting cylinder 72 is assembled to the bottom surface of the inner liner 3 through the fastening unit, the upper sealing surface 191 seals the gap between the inner liner 3 and the connecting bottom plate 75, thereby preventing water leakage from the gap between the blade shaft and the inner liner 3. When the inner pot 3 is embedded in the outer pot, the supporting cylinder 71 and the connecting cylinder 72 are screwed together, and the top edge of the supporting cylinder 71 and the rotating buckle block 73 compress the lower sealing surface 192 of the sealing sleeve 19. On the one hand, the rotating buckle block 73 can completely enter the buckle section 741 and perform subsequent circumferential rotation. On the other hand, the lower sealing surface 192 maintains elastic potential energy, pushing the rotating buckle block 73 to press tightly against the bottom surface of the buckle section 741, avoiding the connecting cylinder 72 from loosening after the buckle is connected, and the avoidance groove 751 makes the lower sealing surface 192 not only compressed by the plane, but also deformed under the action of the top edge of the supporting cylinder 71, thereby increasing the elastic potential energy.

[0054] like Figure 11 As shown, the upper outer side of the rotating buckle block 73 is provided with an axial introduction slope 731 that cooperates with the entrance section 742, and the lower side wall of the rotating buckle block 73 is provided with a screw buckle introduction slope 732 that cooperates with the buckle section 741; the axial introduction slope 731 guides the connecting cylinder 72 to quickly insert into the supporting cylinder 71, and the screw buckle introduction slope 732 converts the circumferential force into an axial force when the connecting cylinder 72 rotates axially relative to the supporting cylinder 71, so that the rotating buckle block 73 can be squeezed into the buckle section 741 from the entrance section 742.

[0055] like Figure 12 As shown, the driving device 4 further includes a mounting bracket 42, a motor 43 and a transmission assembly. The output shaft 41, the motor 43 and the transmission assembly are connected to the mounting bracket 42 and are fastened to the heating plate 24 through the mounting bracket 42, or, as shown Figure 13 As shown, the mounting bracket 42 is integrally formed with the heating plate 24, the driving device 4 is hung and fixedly mounted on the bottom surface of the heating plate 24, constituting an integrated structure of the heating plate 24 and the driving device 4; During fastening assembly, a lower assembly hole 421 is provided on the mounting bracket 42, and an upper assembly hole is provided on the heating plate 24. Fastening units such as screws are passed through the lower assembly hole and the upper assembly hole from bottom to top to fasten the mounting bracket 42 and the heating plate 24.

[0056] The drive device 4 and the heating disk 24 are integrated into one body, which takes up less space and eliminates multiple transmission and installation connection parts. It can be directly connected to the shell or the heating disk 24 in an integrated manner, thereby improving assembly efficiency, reducing manufacturing costs, and ensuring the concentricity of the output shaft 41, with good transmission effect and low failure rate.

[0057] The transmission assembly includes a horizontally arranged turbine 44 and a transversely arranged worm 45. The output shaft 41 is vertically rotatably connected to the mounting bracket 42, and its bottom end is coaxially fixedly connected to the axle of the turbine 44. The motor 43 is laterally fixed to the side of the mounting bracket 42, and its output end is drivingly connected to one end of the worm 45. The worm 45 and the turbine 44 are meshed for transmission. The use of a worm gear and a worm transmission can achieve advantages such as a large single-stage speed ratio, low operating noise, and small vibration. The transmission directions can be arranged vertically without intersecting each other, which can prevent reversal. In addition, the output direction of the motor can be changed, so that the motor can be assembled horizontally in the base 1, thereby reducing the height of the base 1.

[0058] In addition, the worm 45 is made integrally with the output shaft of the motor 43 , which can improve the torsion resistance of the worm 45 , make the rotation of the worm 45 more stable, simplify production, reduce one assembly process, and improve production efficiency.
