[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1

[0031] Please see Figures 1 to 5 As shown, the present invention provides a technical solution where, after one dough kneading operation, the flour easily dries and adheres to the inner wall of the dough bucket 3, requiring personnel to use a wiping cloth to reach inside the dough bucket 3 for cleaning, which is inconvenient. To achieve automatic cleaning of the inside of the dough kneading machine, the specific improvements are as follows:

[0032] A vertical dough mixer for easy cleaning includes a base 1, a fixing rod 2, a dough bucket 3, a top box 4, and a spiral stirring rod 5 rotatably mounted at the bottom of the top box 4. A hollow sleeve 6 is fixedly mounted at the top of the spiral stirring rod 5, and a cleaning brush 7 is movably mounted inside the hollow sleeve 6. A control motor is fixedly mounted on the other side of a support plate, and one end of the output shaft of the control motor is fixedly connected to a first pulley via a coupling. A second pulley is fixedly mounted on the surface of the hollow sleeve 6 inside the top box 4, and the surface of the second pulley is connected to the surface of the first pulley via a belt. When the hollow sleeve 6 rotates, the spiral stirring rod 5 rotates synchronously. Combined with the fixed mounting rod 2 and the rotation of the dough bucket 3, dough mixing can be performed inside the dough bucket 3. The top of the hollow sleeve 6 is... There is a movable part for driving the cleaning brush cylinder 7 to slide up and down. The movable part includes a vertical plate fixedly installed on the top of the top box 4, and a movable plate 10 is slidably installed on one side of the vertical plate. A vertical rod 11 is fixedly installed at the bottom of the movable plate 10, and the bottom end of the vertical rod 11 passes through the hollow sleeve 6 and is fixedly connected to the top of the cleaning brush cylinder 7. An annular iron block 12 is fixedly connected to the bottom of the movable plate 10 and on the surface of the vertical rod 11. An electromagnet is a device that generates electromagnetic fields when energized. A conductive winding matching its power is wound around the outside of the iron core. This coil carrying current has magnetism like a magnet. It is also called an electromagnet. An annular electromagnet 13 is fixedly connected to the top of the hollow sleeve 6. One side of the top of the top box 4 is fixedly connected to one side of the bottom of the movable plate 10 through a buffer spring 14.

[0033] After the dough kneading process is completed, the annular electromagnet 13 is energized by an external switch. The annular electromagnet 13 generates a magnetic attraction force, which attracts the annular iron block 12. When the annular iron block 12 is attracted, it drives the movable plate 10 to slide down along the surface of the vertical plate until the annular iron block 12 contacts the annular electromagnet 13. During the downward sliding process, the movable plate 10, through the setting of the vertical rod 11, can drive the cleaning cylinder 7 to move down along the inside of the hollow sleeve 6 and the middle of the spiral stirring rod 5, thereby cleaning the material adhering to the inner wall of the spiral stirring rod 5. Similarly, the annular electromagnet 13 is de-energized, and the annular electromagnet 13 loses its attraction force. At this time, the annular iron block 12 moves upward under the action of the buffer spring 14, so that the cleaning cylinder 7 moves back to the initial position, so as to avoid the cleaning cylinder 7 affecting the subsequent normal dough kneading process of the spiral stirring rod 5.

[0034] The top surface of the noodle bucket 3 is provided with an annular plate 8, and the surface of the annular plate 8 is provided with an annular cleaning component 9 for cleaning the inner wall of the noodle bucket 3. The annular cleaning component 9 includes an arc-shaped plate 91 fixedly disposed on the inner wall of the annular plate 8 and an annular scraper 93 fixedly disposed on the surface of the annular plate 8. An annular cleaning brush 94 is fixedly disposed on the surface of the annular plate 8 and below the annular scraper 93. A through groove adapted to the fixing rod 2 is opened on one side of the inside of the arc-shaped plate 91, and a wiping cotton 95 is fixedly disposed on the inner wall of the through groove. A cleaning device is fixedly connected to the bottom of the arc-shaped plate 91. Brush 92, the top of the arc plate 91 is provided with a power mechanism for driving the arc plate 91 to move up and down. The power mechanism includes a first gear 15 rotatably disposed on one side inside the top box 4. The first gear 15 is controlled by a first motor inside the top box 4. A convex ring 16 is rotatably disposed on one side of the top of the top box 4 through a Y-shaped limiting ring. A second gear 17 that meshes with the first gear 15 is fixedly disposed on the surface of the convex ring 16. A threaded rod 18 is threadedly connected inside the convex ring 16. The bottom end of the threaded rod 18 is fixedly connected to the top of the arc plate 91.

[0035] The first motor inside the top box 4 is started, causing the first motor to drive the first gear 15 to rotate. The first gear 15 then drives the convex ring 16 to rotate through the second gear 17. At this time, the threaded rod 18 inside the convex ring 16 drives the annular plate 8 to descend along the inner wall of the noodle bucket 3 through the arc plate 91. During the descent, due to the contact between the annular cleaning strip 94 and the annular scraper 93 and the inner wall of the noodle bucket 3, the material adhering to the inner wall of the noodle bucket 3 can be cleaned and scraped off. As the arc plate 91 continues to descend, the surface of the fixed rod 2 can be wiped by the wiping cotton 95. When the arc plate 91 descends to the bottom, the bottom surface of the cleaning brush 92 contacts the bottom of the inner wall of the noodle bucket 3. With the rotation of the noodle bucket 3, the material adhering to the inner wall of the noodle bucket 3 can be thoroughly removed.

[0036] Example 2

[0037] Based on Example 1, please refer to Figure 1 and Figure 2 As shown, to facilitate the automatic discharge of waste liquid and solid impurities generated after cleaning and to achieve the separation of the two, the specific improvements are as follows:

[0038] An outer cylinder 21 is rotatably mounted inside the base 1 and on the surface of the noodle bucket 3. An movable groove adapted to the outer cylinder 21 is opened inside the base 1. A second motor is fixedly mounted at the bottom of the inner wall of the movable groove via a waterproof shell. One end of the output shaft of the second motor is fixedly connected to the bottom end of the outer cylinder 21 via a coupling. The second motor drives the outer cylinder 21 to rotate. Electric push rods 22 are fixedly mounted on both sides of the surface of the outer cylinder 21. The extended ends of the electric push rods 22 are fixed to the surface of the noodle bucket 3 via mounting plates. A discharge component is provided inside the outer cylinder 21, including a support rod fixedly mounted on the bottom of the inner wall of the outer cylinder 21. A sealing plate 23 is fixedly mounted at the top of the support rod, and a sealing ring is fixedly mounted on the surface of the sealing plate 23. A discharge port adapted to the sealing plate 23 is opened on the bottom surface of the noodle bucket 3. Liquid outlet grooves 24 are opened on both sides of the bottom surface of the outer cylinder 21. A filter frame 25 is slidably mounted on one side of the bottom of the base 1, and a drain port is opened on one side of the base 1.

[0039] Activate the electric push rod 22, causing the extended end of the electric push rod 22 to move the dough drum 3 upward to a certain height through the mounting plate. This height is sufficient to open the discharge port. At this time, the waste liquid and solid impurities inside the dough drum 3 fall into the movable tank through the discharge port and the liquid discharge trough, and finally flow into the filter frame 25 through the drain port. After the solid impurities are filtered out by the filter frame 25, the waste liquid is discharged in a concentrated manner. The solid impurities can be cleaned by sliding the filter frame 25 out from the bottom of the base 1.

[0040] Example 3

[0041] Please refer to Embodiment 1 and Embodiment 2 for details. Figure 1 As shown, to facilitate rinsing of the inner wall of the opposite bucket 3, the spiral stirring rod 5, and the surface of the fixing rod 2, the specific improvements are as follows:

[0042] A water pump 19 is fixedly connected to the other side of the top of the top box 4, and the outlet of the water pump 19 is connected to an L-shaped drain pipe 20, and the inlet of the water pump 19 is connected to an inlet pipe. One end of the L-shaped drain pipe 20 passes through the top box 4 and is located above the annular cleaning component 9.

[0043] The water pump 19 draws water from an external source through the inlet pipe and then delivers the water to the inside of the bowl 3 through the L-shaped drain pipe 20, thereby rinsing the inside of the bowl 3. At the same time, it can clean the cleaning brush cylinder 7, wiping cotton 95, cleaning brush 92, as well as the annular cleaning brush strip 94 and annular scraper strip 93, until the adhering substances are completely rinsed away.

[0044] Example 4

[0045] Please refer to Examples 1 to 3. Figure 1 As shown, to achieve rapid drying of the surfaces of the annular cleaning component 9 and the cleaning brush cylinder 7, the specific improvements are as follows:

[0046] The bottom of the top box 4 is fixedly connected to the top of the base 1 through a support plate, and a groove is provided on one side of the support plate. A fan 26 is rotatably installed inside the groove. An electric heating tube 27 is fixedly installed on the surface of the support plate and on one side of the fan 26 through a connecting plate. The electric heating tube 27 is controlled by an external temperature controller to avoid insufficient temperature or overheating.

[0047] After all cleaning work is completed, the ring cleaning component 9 is raised to the initial position, and then the external switch is turned on, which causes the electric heating tube 27 and the blower 26 to start. The electric heating tube 27 heats up to the set temperature, and the blower 26 blows air towards the ring cleaning component 9 and the cleaning brush cylinder 7. When the air passes through the electric heating tube 27, it heats up, which can achieve rapid drying of the ring cleaning component 9 and the cleaning brush cylinder 7 and avoid moisture residue.

[0048] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
