[0041] In the description of the present invention, unless otherwise specified, the terms such as provided, mounted and connected should be understood in a broad sense, and the specific meanings of the terms in the present invention can be reasonably determined by those skilled in the art in light of the specific contents of the technical solutions.

[0042] As shown in FIGS. 1-3, an automatic dough mixer comprises a base 1, a body 2, a dough barrel 3, a stirrer, and a drive motor.

[0043] The base 1 is formed to contain and support the dough mixer. The body 2 is mounted on the base 1 for mounting functional components. The dough barrel 3, the stirrer, and the drive motor are used as functional components and thereby mounted on the body 2.

[0044] The dough barrel 3 is used as a container for dough mixing. The stirrer is arranged above the dough barrel 3 for stirring the flour and water in the dough barrel 3. The drive motor is arranged to drive the stirrer to rotate and stir.

[0045] The stirrer and the drive motor are of conventional configurations of the dough mixer, and thus are not shown in detail.

[0046] As shown in FIGS. 1-3, an angle adjusting mechanism 4 is arranged between the base 1 and the body 2, and the angle adjusting mechanism 4 is operative to adjust the inclination angle of the body 2 relative to the base 1.

[0047] In brief, the functional parts of the entire dough mixer are placed on the base 1, and the dough mixer can be inclined to simulate the situation that the dough barrel 3 is inclined for manually dough mixing.

[0048] This brings the advantages that, the dough can come into contact with the inner wall of the dough barrel 3 in different positions, to adhere more flour from the inner wall of the dough barrel 3, so that the flour can be fully mixed to form a uniform dough, avoiding white points of flour on the surface of the dough, providing better mixing quality, saving subsequent manual intervention, and thus achieving fully automatic dough mixing.

[0049] In addition, as the body 2 on which the dough barrel 3 and the stirrer are mounted can be inclined at different angles, the dough is kneaded in all directions during stirring, resulting in improved quality and mouthfeel of the dough.

[0050] In order to arrange the angle adjusting mechanism 4 reasonably, in some embodiments, the angle adjusting mechanism 4 may be arranged on a side of the body 2 away from the dough barrel 3.

[0051] With such an improved arrangement, as the angle adjusting mechanism 4 is arranged on the side of the body 2 away from the dough barrel 3, the center of gravity of the dough mixer is located between the dough barrel 3 and the angle adjusting mechanism 4, resulting in better stability for dough mixer, and preventing the entire dough mixer from tipping over when the body 2 is inclined relative to the base 1.

[0052] In some embodiments, the angle adjusting mechanism is provided with a plurality of indexing holes and indexing pins for angle adjustment.

[0053] As shown in FIGS. 3 and 4, in some embodiments, the angle adjusting mechanism 4 may comprises a first shaft 41 and a first motor 42.

[0054] The first shaft 41 is fixedly connected to the body 2, the first motor 42 is rotatably connected to the base 1, and accordingly, the body 2 is rotatably connected to the base 1. The first motor 42 is fixedly arranged on the base 1 for driving the first shaft 41 to rotate, then to drive the body 2 to rotate.

[0055] This arrangement may provide the advantages that, the rotatable connection between the body 2 and the base 1 is achieved by the first shaft 41, and the first motor 42 is arranged to drive the first shaft 41 and the body 2 to rotate, for providing the promised angle adjustment. The resulted structure is compact, and only occupies a small space. On the other hand, the first motor 42 is arranged on the base 1, increasing the weight of the base 1, thereby improving the stability of the dough mixer, and preventing the dough mixer from tipping over.

[0056] Alternatively, the first motor 42 may also be fixed to the body 2, and the first shaft 41 is fixed to the base 1 to achieve the same effects.

[0057] In some embodiments, the angle adjusting mechanism 4 may further comprises a gear reduction structure arranged between the first motor 42 and the first shaft 41.

[0058] It can be known by calculation that, as the rotation speed of the first shaft 41 and the body 2 is smaller than that of the first motor 42 while the gear reduction structure is provided, on one hand, the body 2 is slowly rotated and adjusted to a suitable angle, on the other hand, the rotation adjustment has a reduced inertia, and consequently improved stability, on the other hand again, the first motor 42 suffers reduced torque, and thus the body 2 can have a stably maintained inclination angle.

[0059] As shown in FIGS. 3 and 4, in some embodiments in which the gear reduction structure is provided, the gear reduction structure may comprises a large gear 43 sleeved on the first shaft 41 and a pinion connected to an output end of the first motor 42, and the large gear 43 is externally engaged with the pinion.

[0060] It is very advantageous that, increasing the distance between the first motor 42 and the first shaft 41 by the gear reduction structure comprising a large gear 43 and a pinion that are externally engaged with each other, can allow the center of the dough mixer to be close to the middle of the base 1 and thus improve the stability of the dough mixer.

[0061] As shown in FIGS. 3 and 4, in some embodiments, the angle adjusting mechanism 4 may further comprises an upper tile member 44 and a lower tile member 45 that are arranged coaxially and are curved plates.

[0062] The upper tile member 44 is connected to the body 2, the lower tile member 45 is connected to the base 1, and the upper tile member 44 and the lower tile member 45 in cooperation with each other forms a space for receiving the large gear 43.

[0063] In order to reasonably control the range of rotation of the body 2, the upper tile member 44 may abut against the base 1, or the lower tile member 45 may abut against the body 2 to restrict the rotation of the body 2.

[0064] Significantly, the upper tile member 44 and the lower tile member 45 can cover the large gear 43 to avoid accidents.

[0065] In addition, the upper tile member 44 or the lower tile member 45 can prevent further rotation of the body 2, thereby preventing the dough mixer from tipping over due to excessive rotation of the body 2.

[0066] As shown in FIG. 3, in some embodiments, the base 1 may comprise a bottom shell 11, a first cover 12, and a second cover 13.

[0067] The bottom shell 11 is constructed to form an actual support and placement site for the dough mixer. The first cover 12 and the second cover 13 are arranged to cover the bottom shell 11 for aesthetics.

[0068] In some embodiments, the second cover 13 is higher than the first cover 12, and the second cover 13 is arrange to cooperate with the bottom shell 11 for receiving the first motor 42.

[0069] Significantly, the base 1 comprises a bottom shell 11, a first cover 12, and a second cover 13, this arrangement is weight reducing and cost saving.

[0070] Furthermore, since the second cover 13 and the bottom shell 11 are in cooperation to receive the first motor 42, the first motor 42 can be easily maintained by disassembling the second cover 13.

[0071] As shown in FIG. 3, in some embodiments, the body 2 may be provided with a first chamber, the first chamber is formed at the bottom of the body 2, to allow the pass through of the first motor 42, that is, when the body 2 rotates, the first motor 42 can move in and move out the first chamber without interference.

[0072] By providing the first chamber in this embodiment, a projecting portion of the base 1 for receiving the first motor 42 can be received by the body 2 without increasing the height of the dough mixer, the dough mixer is thus compact in structure.

[0073] In some embodiments, as shown in FIGS. 5-7, the dough barrel 3 may be rotatably connected to the body 2, and the body 2 is provided with a second motor 5 that drives the dough barrel 3 to rotate.

[0074] In this embodiment, the rotatable dough barrel 3 and the second motor 5 that drives the dough barrel 3 to rotate are provided to improve the relative speed of the stirrer and the flour, for improved mixing efficiency, and shortened mixing time. In addition, the relative speed of the stirrer and the flour can be adjusted by adjusting the output of the second motor 5 to provide multiple adjustment modes, facilitating the mixing of the flours of different masses, and improving the mixing effect. Moreover, the use of the second motor 5 instead of the drive motor to drive the dough barrel 3 to rotate can bring about an optimized transmission structure, without influence on the disassembly and assembly of the stirrer and the use and cleaning of the dough barrel 3.

[0075] Furthermore, when the body 2 is inclined, the wall of the dough barrel 3 can rotate to a position close to the bottom of the dough barrel 3 and come into contact with the dough therein, this arrangement allow the flour to be completely and uniformly mixed into the dough.

[0076] In some embodiments in which a second motor 5 is provided, and arranged between the dough barrel 3 and the angle adjusting mechanism 4.

[0077] Since the second motor 5 is arranged between the dough barrel 3 and the angle adjusting mechanism 4, the internal space of the dough barrel 3 can be fully utilized and thus the external size of the dough mixer will not be increased, and the center of gravity of the dough mixer can remain at the geometric center for improved stability of the dough mixer.

[0078] To be precise, as shown in FIG. 3, the box 21 is provided with a column 6 for mounting the stirrer and the drive motor, and the second motor 5 is arranged between the column 6 and the swivel 22.

[0079] Similarly, since the second motor 5 is arranged between the column 6 and the swivel 22, the space can be fully utilized, and thus the dough mixer is compact in structure and occupies a small space.

[0080] More specifically, as shown in FIGS. 5-7, the body 2 comprises a box 21 provided with a swivel 22 for mounting the dough barrel 3, the second motor 5 is arranged in the box 21, and a gear transmission structure is arranged in the box 21 and between the swivel 22 and the second motor 5.

[0081] Obviously, power is reliably transmitted by gear transmission, and arranging the gear transmission structure and the second motor 5 within the box 21 can avoid exposure and thus be well protected.

[0082] In some embodiments, the second motor 5 may have an axis direction perpendicular to the connection direction of the swivel 22 and the column 6.

[0083] Arranging the axis direction of the second motor 5 along the width direction of the dough mixer does not increase the length of the dough mixer, and rarely affects the appearance of the dough mixer.

[0084] In some embodiments, the gear transmission structure may comprises a first transmission shaft 25 arranged coaxially with the swivel 22, first transmission shaft 25 has a top end inserted into and connected to the swivel 22, and the box 21 is provided with a first positioning hole 23 for receiving a bottom end of the first transmission shaft 25.

[0085] The disassembly and assembly of the first transmission shaft 25 is effectively facilitated, and two ends of the first transmission shaft 25 are limited to prevent the first transmission shaft 25 from swinging due to the transmission.

[0086] In some embodiments in which the first transmission shaft 25 is arranged, the gear transmission structure may further comprise a second transmission shaft 26 for a transmission connection between the first transmission shaft 25 and the second motor 5, and a support 27 for mounting the first transmission shaft 25 and the second transmission shaft 26. The support 27 is connected to the tops of the first transmission shaft 25 and the second transmission shaft 26, and the box 21 is provided with a second positioning hole 24 for receiving a bottom end of the second transmission shaft 26.

[0087] After the top or bottom of the box 21 is removed, the entire gear transmission structure can be directly removed, this arrangement allows convenient disassembly and assembly and easy maintenance for the entire gear transmission structure.

[0088] In some embodiments, the swivel 22 may be provided with a mounting cavity for receiving a bottom end of the dough barrel 3, the dough barrel 3 is provided with a plurality of stop pins 222 arranged on the outer side thereof, and the mounting cavity is provided with stop buckles 221 arranged on the inner side thereof for clamping the stop pins 222.

[0089] The provision of the stop buckles 221 and the stop pins 222 provides convenience for the disassembly, assembly and cleaning of the dough barrel 3.

[0090] In some embodiments in which stop buckles 221 are provided, the stop buckles 221 comprises lateral buckle slots extending circumferentially along the swivel 22 and longitudinal buckle slots extending axially along the swivel 22.

[0091] The lateral buckle slots prevent the dough barrel 3 from flying off during rotation, and the power of the second motor 5 can be transmitted to the dough barrel 3 by the longitudinal buckle slots so as to drive the dough barrel 3 to rotate.

[0092] The above embodiments are not limited to the technical solutions of the embodiments, and may be combined with each other to form new embodiments. The above embodiments are only for describing the technical solutions of the present invention, rather than limiting the present invention. Any modifications or equivalent substitutions made without departing from the spirit and scope of the present invention shall fall into the scope of the technical solutions of the present invention.
