Description

Technical Field

[0001] The present application relates to the technical field of small household appliances, and more specifically, to a food processor base and a food processor. Background Art

[0002] Some food processors use the motor's built-in fan to dissipate heat. When the fan rotates, it will intensify the vibration of the motor and the entire machine, and will also affect the dynamic balance of the motor. When running at high speed, the fan will also cause loud noise. Summary of the Invention

[0003] The present application provides a food processor base and a food processor, which can reduce vibration and noise.

[0004] A food processor base, comprising:

[0005] The housing is provided at the outermost side of the base and is provided with a housing air inlet for the entry of cool air and a housing air outlet for the exhaust of hot air;

[0006] A motor cover and a chimney-type air outlet pipe are provided in the housing, the motor cover is provided with an air inlet and a receiving cavity that are connected to each other, the bottom end of the chimney-type air outlet pipe is connected to the receiving cavity, and the top end is provided with an air outlet, the air outlet is higher than the air inlet, the air inlet is connected to the air inlet of the housing, and the air outlet is connected to the air outlet of the housing;

[0007] The motor is encapsulated in the receiving cavity.

[0008] In this application, the chimney-style air outlet pipe mimics the chimney setting, forming a chimney-style air outlet duct. When the motor is operating, a high-temperature, high-pressure area forms inside the housing chamber, while the outside is a low-temperature, low-pressure area. A pressure difference exists between the high-temperature, high-pressure area and the low-temperature, low-pressure area, causing the hot air to flow toward the low-temperature, low-pressure area. The hot air can then be discharged through the heat dissipation duct, effectively achieving heat dissipation of the motor. Furthermore, the base can also omit the fan, which correspondingly reduces the vibration and noise caused by the fan.

[0009] Optionally, the chimney-type air outlet pipe is connected to the receiving chamber at the bottom of the motor cover and extends vertically upward along the height direction of the machine base. In this configuration, the chimney-type air outlet pipe can be set longer, and the chimney effect is better, so that the hot air in the receiving chamber can be better discharged through the chimney-type air outlet pipe. In addition, the chimney-type air outlet pipe extends vertically upward, and the structure after assembly with the motor cover is more compact.

[0010] Optionally, the chimney-type air outlet pipe has a dimension of not less than 10 mm in the height direction of the base. According to the chimney effect, the higher the height of the chimney-type air outlet pipe, the better the heat dissipation effect and the faster the exhaust speed.

[0011] Optionally, the motor cover is configured as a stepped structure with a larger diameter at the top and a smaller diameter at the bottom, the air inlet being provided on a stepped surface of the stepped structure, and the air inlet penetrating the stepped surface. This configuration allows a stepped surface to be formed inside the motor cover, facilitating the provision of the air inlet.

[0012] Optionally, the motor cover is further provided with a connecting port, the chimney-type air outlet pipe is connected to the motor cover at the connecting port, and the connecting port is lower than the air inlet. This arrangement can increase the height of the chimney-type air outlet pipe, thereby increasing the heat dissipation effect and exhaust speed.

[0013] Optionally, there are one or more air inlets, and at least one of the air inlets is spaced 180 degrees from the communication port. This arrangement maximizes the angle between the communication port and the air inlet, increases the ventilation path, and facilitates sufficient heat exchange of the cold air within the receiving chamber.

[0014] Optionally, one or more air inlets are provided, and at least one of the air inlets is located on the side where the air inlet of the housing is located. This arrangement allows at least one air inlet to be closer to the air inlet of the housing, thereby shortening the ventilation path and facilitating rapid entry of cold air into the air inlet via the air inlet of the housing.

[0015] Optionally, the housing air inlet is lower than the air inlet. With this arrangement, cold air can enter the air inlet along the shortest path.

[0016] Optionally, the ventilation area of ​​the air outlet of the housing is larger than the ventilation area of ​​the air outlet, so as to ensure smoother exhaust.

[0017] Optionally, the base further includes a PCB board, and the PCB board is arranged in a channel connecting the air inlet of the housing and the air inlet, which is also conducive to heat dissipation of the PCB board.

[0031] Please refer to Figure 1 , Figure 1 Schematic diagram of a food processor 100 according to an exemplary embodiment of the present application.

[0032] The present application provides a food processor 100, which includes a base 10 and a cup assembly 20, wherein the cup assembly 20 is assembled on the base 10. For example, the cup assembly 20 is detachably assembled on the base 10. The food processor 100 includes but is not limited to a wall-breaking machine.

[0033] The cup assembly 20 includes a cup body and a blending blade. The cup body defines a cup cavity for holding ingredients. The blending blade includes a blade shaft and blades connected to the shaft. The blade shaft extends from the bottom of the cup body and engages with the rotor of the motor within the base 10. The blades are located within the cup cavity and are used to blend and crush ingredients. The number of blades is not limited; one or more blades may be provided.

[0034] Please refer to Figure 2 , Figure 2 for Figure 1 An exploded view of the base 10 is shown in FIG.

[0035] The base 10 includes a housing 11, a motor cover 12 and a motor 13. The housing 11 is located at the outermost side of the base 10 and serves as the exterior of the base 10. The housing 11 includes a detachably connected bottom shell 110 and an upper cover 112, which together form a receiving space 114 (see Figure 3 The motor cover 12 and the motor 13 are both accommodated in the accommodation space 114 , and the motor 13 is also disposed in the motor cover 12 .

[0036] The base 10 further includes a PCB fixing frame 14 disposed in the accommodation space 114. The PCB fixing frame 14 is used to fix and protect the PCB board 19 (see Figure 5 ).

[0037] Please refer to Figure 3 , Figure 3 It is a cross-sectional view of the machine base 10 .

[0038] In one embodiment, the motor 13 is enclosed within the space enclosed by the motor cover 12 and the upper cover 112. Specifically, a first sealing ring 15 is sandwiched between the top of the motor cover 12 and the upper cover 112 to seal the gap between the motor cover 12 and the upper cover 112, preventing gas from flowing in and out of the gap between the motor cover 12 and the upper cover 112. A second sealing ring 16 is also sandwiched between the motor 13 and the upper cover 112 to seal the gap between the motor 13 and the upper cover 112. The second sealing ring 16 is disposed around the rotating shaft 130 of the motor 13 to prevent gas from flowing in and out of the rotating shaft 130.

[0039] Please refer to Figure 4 and Figure 5 , Figure 4 It is another cross-sectional view of the base 10. Figure 5 It is another exploded view of the base 10 .

[0040] In one embodiment, the base 10 further includes motor shock-absorbing pads 17, which are used to mitigate and absorb vibrations generated by the motor 13. Specifically, the motor 13 is provided with multiple mounting holes 131, and a corresponding number of motor shock-absorbing pads 17 are provided. The motor shock-absorbing pads 17 are hollow, with radially protruding flanges at both ends. The multiple motor shock-absorbing pads 17 are correspondingly mounted within the mounting holes 131, with the flanges at both ends located outside the mounting holes 131.

[0041] The upper cover 112 is provided with a plurality of mounting posts 1120 protruding toward the bottom shell 110. The mounting posts 1120 are a stepped structure. The motor cover 12 is also provided with a plurality of matching mounting holes 120. The plurality of mounting posts 1120, the plurality of mounting holes 131 and the plurality of matching mounting holes 120 correspond one to one. The flanges at both ends of the motor shock-absorbing pad 17 are respectively clamped between the stepped surface of the mounting post 1120 and the motor 13 and between the motor cover 12 and the motor 13. The clamping force comes from the bolts. The bolts pass through the mounting holes 131 and the matching mounting holes 120 and are screwed into the mounting posts 1120. In this way, the motor 13 is isolated from the upper cover 112 and the motor cover 12 on both the upper and lower sides through the motor shock-absorbing pad 17, thereby achieving vibration reduction of the motor 113.

[0042] Please combine Figure 5 and Figure 6 , Figure 6 It is a cross-sectional view of a partial structure of the base 10.

[0043] The motor cover 12 is provided with a communicating air inlet 121 and a receiving chamber 122, within which the motor 13 is housed. As previously described, the first sealing ring 15 seals the gap between the motor cover 12 and the upper cover 112, while the second sealing ring 16 seals the gap between the motor shaft 130 and the upper cover 112. This ensures that the motor 13 is completely sealed within the receiving chamber 122, ensuring that the heat generated by the motor 13 can be discharged along a predetermined path.

[0044] Among them, the first sealing ring 15 is installed in the first sealing groove 1122 of the upper cover 112, and the second sealing ring 16 is installed in the second sealing ring groove 1123 of the upper cover 112. A through hole 1121 through which the power supply shaft 130 extends is provided in the middle part of the upper cover 112. The second sealing ring groove 1123 surrounds the periphery of the through hole 1121, and the first sealing groove 1122 surrounds the periphery of the second sealing ring groove 1123.

[0045] Please combine Figure 5 and Figure 8As shown, the housing 11 is provided with a housing air inlet 1101 and a housing air outlet 1102. The air inlet 121 communicates with the outside world through the housing air inlet 1101 for the entry of cool air, and the air outlet 124 communicates with the outside world through the housing air outlet 1102 for the exit of hot air after heat exchange. For example, the housing air inlet 1101 can be provided on the bottom surface of the bottom housing 110, and the housing air outlet 1102 can be provided on the side of the upper cover 112, but the present invention is not limited thereto.

[0046] The shell 11 also includes a chimney-type air outlet pipe 123, the bottom end of which is connected to the accommodating cavity 122, and the top end is set as an air outlet 124, which is higher than the air inlet 121. The air inlet 121 is connected to the shell air inlet 1101, and the air outlet 124 is connected to the shell air outlet 1102.

[0047] According to the above description, the bottom end of the chimney-type air outlet pipe 123 is connected to the receiving chamber 122, and the top end is provided with an air outlet 124, and the air outlet 124 is higher than the air inlet 121. The chimney-type air outlet pipe 123 imitates the chimney setting and forms a chimney-type air outlet. When the motor 13 is working, a high-temperature and high-pressure area will be formed in the receiving chamber 122, and the outside will be a low-temperature and low-pressure area. There is a pressure difference between the high-temperature and high-pressure area and the low-temperature and low-pressure area. The pressure difference causes the hot air to flow to the low-temperature and low-pressure area. The hot air can be discharged from the chimney-type air outlet pipe 123, effectively achieving the heat dissipation of the motor 13. The base 10 can also omit the fan, which correspondingly reduces the vibration and noise caused by the fan.

[0048] In one embodiment, Figure 5 As shown, the chimney-style air outlet pipe 123 is connected to the receiving chamber 122 at the bottom of the motor cover 12 and extends vertically upward along the height direction of the base 10. This configuration allows the chimney-style air outlet pipe 123 to be longer, achieving a better chimney effect, allowing the hot air in the receiving chamber 122 to be better discharged through the chimney-style air outlet pipe 123. In addition, the chimney-style air outlet pipe 123 extends vertically upward, making the structure more compact when assembled with the motor cover 12.

[0049] exist Figure 5 In the embodiment shown, the chimney-type air outlet pipe 123 is connected to the side wall of the bottom of the motor cover 12. Of course, in other embodiments, the chimney-type air outlet pipe 123 can be connected to the receiving chamber 122 at the top of the motor cover 12.

[0050] The motor cover 12 and the chimney-style air outlet duct 123 can be integrally formed, but are not limited thereto. They can also be provided as separate components and assembled together. The cross-sectional shape of the chimney-style air outlet duct 123 is not limited, including but not limited to square, cylindrical, or conical shapes. The shape of the air outlet 124 is not limited.

[0051] exist Figure 6 In the embodiment shown, a shell air outlet 1102 is provided on the side of the upper cover 112, and the end of the chimney-type air outlet pipe 123 is bent toward the side away from the motor cover 12, so that the air outlet 124 of the chimney-type air outlet pipe 123 is directly opposite to the shell air outlet 1102 on the side of the upper cover 112, thereby shortening the exhaust path of the airflow and facilitating smoother exhaust of hot air.

[0052] In one embodiment, the height H of the chimney-type air outlet duct 123 is not less than 10 mm. According to the chimney effect, the higher the height of the chimney-type air outlet duct 123, the better the heat dissipation effect and the faster the exhaust speed. The height of the chimney-type air outlet duct 123 can be set according to the height and structure of the base 10.

[0053] In one embodiment, Figure 6 As shown, the motor cover 12 is configured as a stepped structure with a large top diameter and a small bottom diameter, that is, the motor cover 12 includes a main body large end 125 and a main body small end 126, and a stepped surface 127 is formed at the portion where the main body large end 125 and the main body small end 126 meet, and the air inlet 121 passes through the stepped surface 127 of the stepped structure. This configuration allows a stepped surface 127 to be formed inside the motor cover 12, facilitating the arrangement of the air inlet 121 and allowing cold air to enter the receiving chamber 122 through the air inlet 121. Multiple air inlets 121 can be arranged at intervals on the stepped surface 127. It should also be noted that the stepped structure of the motor cover 12 also facilitates the arrangement of the matching mounting holes 120, which are also provided on the stepped surface 127.

[0054] In one embodiment, Figure 5 and Figure 6 As shown, the motor cover 12 is further provided with a communication port 128, at which the chimney-style air outlet pipe 123 connects to the motor cover 12. The communication port 128 is positioned lower than the air inlet 121. This arrangement increases the height of the chimney-style air outlet pipe 123, thereby enhancing heat dissipation and exhaust speed. Of course, in other embodiments, the communication port 128 can be flush with the air inlet 121, or higher than the communication port 128.

[0055] In one embodiment, the communication port 128 is spaced 180 degrees from the air inlet 121 . This arrangement maximizes the angle between the communication port 128 and the air inlet 121 , increases the ventilation path, and facilitates sufficient heat exchange of cold air within the receiving chamber 122 .

[0056] Please combine Figure 3 and Figure 7 , Figure 7 It is a schematic diagram of the structure of the base 10.

[0057] In one embodiment, the housing air inlet 1101 allows cool air from the outside to enter. The housing air inlet 1101 is connected to the air inlet 121. There may be one or more air inlets 121, with at least one air inlet 121 located on the side of the housing air inlet 1101. This arrangement allows at least one air inlet 121 to be closer to the housing air inlet 1101, shortening the ventilation path and facilitating quick entry of cool air into the air inlet 121 via the housing air inlet 1101.

[0058] In one embodiment, the housing air inlet 1101 is lower than the air inlet 121. With this arrangement, cold air can enter the air inlet 121 along the shortest path.

[0059] In one embodiment, the housing air outlet 1102 is used to discharge heated air, and the housing air outlet 1102 is directly opposite to the air outlet 124. The ventilation area of ​​the housing air outlet 1102 is larger than the ventilation area of ​​the air outlet 124. This ensures smoother exhaust. Figure 3 The arrows in FIG. 1 show the flow path of air in the base 10 .

[0060] like Figure 3 and Figure 5 As shown, in order to ensure the sealing of the connection between the outer shell air outlet 1102 and the air outlet 124, the base 10 also includes a third sealing ring 18. The third sealing ring 18 is clamped between the chimney-type air outlet pipe 123 and the outer shell 11. The third sealing ring 18 surrounds the outer periphery of the outer shell air outlet 1102 and the air outlet 124 to ensure that hot air is discharged from the air outlet 124 and the outer shell air outlet 1102.

[0061] In one embodiment, Figure 5 As shown, the PCB board 19 is arranged in a channel connecting the housing air inlet 1101 and the air inlet 121 , which is also beneficial to heat dissipation of the PCB board 19 .

[0062] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
