Description

Technical Field

[0001] This application relates to the technical field of small household appliances, and more specifically, to a main body of a cooking machine and a cooking machine. Background Art

[0002] The main body of a cooking machine includes a motor, and a motor shaft extends out of the main body to transmit power to a knife assembly in a cooking cup. Sealing treatment is required at the part where the motor shaft extends. For example, a sealing ring is provided between the motor shaft and the main body housing. After being assembled, the sealing ring is pressed by the main body housing and the motor shaft, so as to form interference with both the motor shaft and the main body housing, preventing liquid from flowing into the interior of the main body.

[0003] In the above sealing structure, the sealing ring is fixed. After being squeezed by the main body housing and the motor shaft, the sealing ring forms interference with the motor shaft, resulting in a large frictional force between the motor shaft and the sealing ring when the motor shaft rotates, serious heating of the motor shaft, and high energy consumption of the motor. Summary of the Invention

[0004] This application provides a main body of a cooking machine and a cooking machine, which can achieve the sealing of the motor shaft and reduce the energy consumption of the motor.

[0005] A main body of a cooking machine includes:

[0006] A main body housing provided with a shaft hole;

[0007] A motor shaft extending out of the main body housing through the shaft hole, and the motor shaft is in clearance fit with the shaft hole;

[0008] A sealing ring sleeved on the motor shaft, the sealing ring rotates synchronously with the motor shaft, and seals the shaft hole.

[0009] In this application, the sealing ring rotates synchronously with the motor shaft and can also seal the shaft hole, which not only realizes the sealing of the shaft hole by the sealing ring, but also avoids friction between the motor shaft and the sealing ring when the motor shaft rotates, thereby reducing the energy consumption of the motor.

[0010] Optionally, in the orthographic projection along the axial direction of the motor shaft, the projection area of the clearance between the shaft hole and the motor shaft is located within the projection area of the sealing ring. With such a setting, the sealing ring can block the clearance between the upper cover and the motor shaft to achieve the sealing of the shaft hole.

[0011] Optionally, the sealing ring includes a sealing sleeve and an annular sealing flange protruding radially outward along the sealing sleeve. The sealing sleeve is sleeved on the motor shaft and remains relatively fixed to the motor shaft, and the annular sealing flange blocks above the shaft hole. With such a setting, the sealing sleeve can be reliably fixed to the motor shaft, and the annular sealing flange can be used to block the shaft hole, resulting in better sealing performance.

[0012] Optionally, the main housing includes a convex portion extending upward, and the space enclosed by the convex portion forms the shaft hole. With such a setting, since the convex portion extends upward, the shaft hole provided at the convex portion is closer to the sealing ring, so that the sealing effect of the sealing ring on the shaft hole is better.

[0013] Optionally, the outer peripheral edge of the sealing flange is bent downward and surrounds and wraps the periphery of the convex portion. With such a setting, the sealing flange has a covering effect and can cover the convex portion therein, thereby covering the shaft hole therein, thus achieving effective waterproof sealing of the shaft hole.

[0014] Optionally, the sealing sleeve is in clearance fit with the shaft hole. That is to say, the aperture of the shaft hole is larger than the outer diameter of the sealing sleeve. This can prevent the sealing sleeve from rubbing against the upper cover when rotating with the motor shaft, increasing the motor energy consumption, and also facilitating the installation of the sealing ring.

[0015] Optionally, the upper surface of the main housing further includes a recessed portion recessed downward, and the recessed portion surrounds and connects to the periphery of the convex portion. The recessed portion recessed downward can be used to collect accumulated water, and the liquid blocked by the sealing ring can be collected by the recessed portion.

[0016] Optionally, the main housing is further provided with a drainage portion, and the drainage portion is communicated with the recessed portion. The drainage portion can drain the liquid accumulated in the recessed portion.

[0017] Optionally, the drainage portion includes a drainage groove. One end of the drainage groove is communicated with the recessed portion, and the other end extends to the edge of the main housing. The bottom surface of the drainage groove gradually slopes downward from the recessed portion. The drainage groove can discharge the liquid in the recessed portion to the outside of the main housing, avoiding the risk of short circuit and the like caused by entering the main body, and the structure of the drainage groove is simple, facilitating processing and manufacturing.

[0018] Optionally, a groove extending circumferentially is provided on the outer surface of the motor shaft, and the sealing ring is sleeved in the groove. The groove is used for limiting and fixing, preventing the sealing sleeve from axially moving along the motor shaft, and improving the stability of the installation position of the sealing ring.

[0031] Please refer to Figure 1 and Figure 2 , Figure 1 which is a schematic diagram of a cooking machine 100 shown in an exemplary embodiment of the present application Figure 2 is Figure 1 a cross-sectional view of the cooking machine 100 shown in

[0032] The present application provides a cooking machine 100, which includes but is not limited to a wall breaker, a juicer, and a juice extractor

[0033] The cooking machine 100 includes a main body 10 and a cooking cup 20. The cooking cup 20 is installed on the main body 10. For example, the cooking cup 20 is detachably installed on the top of the main body 10. The cooking cup 20 can be provided with a juice outlet 21 and a residue discharge port 23, and both the juice outlet 21 and the residue discharge port 23 communicate with the stirring cavity 22 of the cooking cup 20

[0034] The cooking machine 100 further includes a food processing component 30 installed in the cooking cup 20. The main body 10 is connected to the rotating shaft of the food processing component 30 and is used to drive the food processing component 30 to rotate. The food processing component 30 is located in the stirring cavity 22 and is used to process food ingredients. According to the different food ingredients processed by the cooking machine 100, the structure of the food processing component 30 can be different. In a specific embodiment, the food processing component 30 may include a screw and is used to make fruit juice.

[0035] Please refer to Figures 3 to 6 , Figure 3 which is a schematic diagram of the main body 10. Figure 4 which is a sectional view of the main body 10. Figure 5 which is an exploded view of the main body 10. Figure 6 which is an enlarged view of a sectional view of a partial structure of the main body 10.

[0036] The main body 10 includes a main body housing 11, a motor shaft 12 extending out of the main body housing 11, and a sealing ring 13. In one embodiment, as Figure 5 shown, the main body housing 11 may include a bottom shell 110, a shell body 111, and an upper cover 112 that are separately provided. The bottom shell 110 is provided at the bottom, the upper cover 112 is provided at the top, and the shell body 111 connects the bottom shell 110 and the upper cover 112. The bottom shell 110, the shell body 111, and the upper cover 112 together enclose a receiving cavity 101 (refer to Figure 4 ), and the main body 10 further includes a motor 14 housed in the receiving cavity 101. The motor shaft 12 is the rotating shaft of the motor 14.

[0037] As Figure 6 shown, the main body housing 11 is provided with a shaft hole 102. Specifically, the upper cover 112 is provided with the shaft hole 102. The motor shaft 12 extends out from the shaft hole 102 of the upper cover 112. The motor shaft 12 has a clearance fit with the shaft hole 102, and the motor shaft 12 can rotate relative to the upper cover 112.

[0038] The sealing ring 13 is sleeved on the motor shaft 12 and rotates synchronously with the motor shaft 12. The sealing ring 13 seals the shaft hole 102. For example, the motor shaft 12 and the sealing ring 13 can be assembled by an interference fit or a tight fit, but not limited thereto.

[0039] According to the above description, it can be known that the sealing ring 13 rotates synchronously with the motor shaft 12 and can also seal the shaft hole 102, which avoids friction between the motor shaft 12 and the sealing ring 13 when the motor shaft 12 rotates, thereby reducing the energy consumption of the motor 14.

[0040] In one embodiment, in the orthographic projection along the axial direction of the motor shaft 12, the projection area of the gap between the shaft hole 102 and the motor shaft 12 is located within the projection area of the sealing ring 13. With such a setting, the sealing ring 13 can block the gap between the upper cover and the motor shaft, achieving the sealing of the shaft hole 102. For example, at least a part of the sealing ring 13 is located above the upper cover 112, blocking and sealing the shaft hole 102 from above. Also, for example, at least a part of the sealing ring 13 is located below the upper cover 112, blocking and sealing the shaft hole 102 from below. In this embodiment, the former is adopted.

[0041] In one embodiment, as Figure 6 shown, the upper cover 112 includes a convex portion 1120 protruding upward, and the space surrounded by the convex portion 1120 forms the shaft hole 102. With such a setting, the convex portion 1120 extends upward and protrudes above the upper cover 112, which makes it not easy to accumulate water at the convex portion 1120, reducing the risk of water entering the shaft hole 102; and the convex portion 1120 extends upward, making the shaft hole 102 provided at the convex portion 1120 closer to the sealing ring 13, so that the blocking effect of the sealing ring 13 on the shaft hole 102 is better.

[0042] Continue to refer to Figure 6 , in one embodiment, the upper cover 112 further includes a concave portion 1121 recessed downward, and the concave portion 1121 surrounds and connects to the periphery of the convex portion 1120. The concave portion 1121 is recessed downward and can be used to collect accumulated water. The liquid blocked by the sealing ring 13 can be collected by the concave portion 1121 to prevent the accumulated water from flowing out.

[0043] In one embodiment, the sealing ring 13 includes a sealing sleeve 130 and an annular sealing flange 131 protruding radially outward and extending circumferentially along the sealing sleeve 130, and the sealing sleeve 130 is relatively fixed with the motor shaft 12. For example, the sealing sleeve 130 is in interference fit or tight fit with the motor shaft 12, etc. With such a setting, the sealing sleeve 130 can be reliably fixed to the motor shaft 12, and the annular sealing flange 131 can be used to block the shaft hole 102, with better sealing performance.

[0044] In Figure 6In the illustrated embodiment, the bottom of the sealing sleeve 130 is located within the shaft hole 102, the annular sealing flange 131 is connected to the top of the sealing sleeve 130, and the convex portion 1120 is disposed within the space below the annular sealing flange 131. With this arrangement, below the annular sealing flange 131, an annular space is formed between the annular sealing flange 131 and the sealing sleeve 130, and the convex portion 1120 is located within this annular space. Through the spatial cooperation of the convex portion 1120 with the sealing sleeve 130 and the annular sealing flange 131, the shaft hole 102 can be better shielded, further reducing the risk of water entering the main body 10 from the shaft hole 103, and further enhancing the sealing effect.

[0045] In one embodiment, the outer peripheral edge of the annular sealing flange 131 bends downward and surrounds and covers the periphery of the convex portion 1120. With this arrangement, the annular sealing flange 131 has a covering effect and can cover the convex portion 1120 therein, thereby covering the shaft hole 102 therein, and well achieving the waterproof sealing of the shaft hole 102. Moreover, the four peripheral edges of the sealing flange 131 bend downward, which can also prevent water from accumulating on the sealing flange 131. The upper surface of the sealing flange 131 can be provided with an arc surface.

[0046] In one embodiment, the sealing sleeve 130 and the shaft hole 102 are in clearance fit. That is to say, the inner diameter of the shaft hole 102 is larger than the outer diameter of the sealing sleeve 130. This can prevent the sealing sleeve 130 from rubbing against the upper cover 112 when the sealing sleeve 130 rotates with the motor shaft 12, increasing the motor energy consumption, and also facilitating the installation of the sealing ring 13.

[0047] In one embodiment, a groove 120 extending circumferentially is provided on the outer surface of the motor shaft 12, and the sealing ring 13 is sleeved within the groove 120. This groove 120 is used to play a role of limiting and fixing, preventing the sealing ring 13 from axially moving along the motor shaft 12, and improving the stability of the installation position of the sealing ring 13.

[0048] Please refer to again Figure 3 , in one embodiment, the upper cover 112 is further provided with a drainage portion 1123, and the drainage portion communicates with the recess 1121. The drainage portion can drain the liquid accumulated in the recess 1121.

[0049] The drainage portion 1123 can be a drainage hole. In this embodiment, the drainage portion 1123 includes a drainage groove. One end of the drainage groove communicates with the recess 1121, and the other end extends to the edge of the upper cover 112. The bottom surface of the drainage groove gradually slopes downward from the recess 1121. With this arrangement, the drainage groove can enable the liquid in the recess 1121 to be discharged from the outside of the main body housing 11, preventing it from entering the main body 10 and causing risks such as short circuits. Moreover, the drainage groove has a simple structure and is convenient for processing and manufacturing.

[0050] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the scope of protection of the present application.
