Description

Technical Field

[0001] This application relates to the field of food processing, and particularly to a cooking machine. Background Art

[0002] With the increasing improvement of people's living standards, many different types of cooking machines have emerged on the market. The functions of a food processor mainly can include, but are not limited to, functions such as making soy milk, squeezing juice, mincing meat, making shaved ice, making coffee, and / or preparing facial masks. A cooking machine includes a motor, a mixing cup, and a chassis provided at the bottom of the mixing cup. The output shaft of the motor passes through the chassis, and a grease seal is provided between the output shaft and the chassis. In an existing cooking machine, since the grease seal is prone to wear during the operation of the motor, the output shaft and the chassis are prone to water leakage. Utility Model Content

[0003] The purpose of this application is to provide a cooking machine that can effectively avoid water leakage at the bottom of the mixing cup.

[0004] This application provides a cooking machine. The cooking machine includes a mixing cup, a chassis, a motor, and a mixing blade. The chassis is fixed to the bottom of the mixing cup. The motor includes a main body part and an output shaft. The output shaft passes through the chassis. The mixing blade is provided at the top end of the output shaft. A seal is formed between the output shaft and the chassis through a grease seal. The output shaft is provided with a shaft sleeve. The shaft sleeve presses downward against the main body part, and the shaft sleeve presses the grease seal upward against the chassis. Since the two ends of the shaft sleeve respectively press against the main body part of the motor and the grease seal, the vibration generated by the motor during operation can be transmitted to the grease seal through the shaft sleeve. In this way, the grease seal can vibrate together with the main body part of the motor, thereby avoiding the motor from squeezing the grease seal, and further causing wear to the grease seal. Thus, the wear on the grease seal can be reduced, the sealing performance between the output shaft and the chassis is more reliable, and water leakage during the use of the cooking machine can be effectively avoided.

[0005] Further, the output shaft is further provided with a corrugated gasket, and the corrugated gasket is provided between the shaft sleeve and the grease seal. Since the corrugated gasket has good elastic force, it can avoid the corrugated gasket from causing excessive wear to the grease seal, thereby ensuring that the grease seal has good sealing performance.

[0006] Further, the shaft sleeve is provided with an upwardly protruding annular rib, and the corrugated gasket is sleeved outside the rib. In this way, through the cooperation of the rib and the corrugated gasket, the shaft sleeve can more reliably drive the corrugated gasket to vibrate through the rib, and then drive the grease seal to vibrate together. Thus, the wear on the grease seal is smaller, and the sealing performance is more stable.

[0007] Further, the chassis is provided with a sleeve portion surrounding the output shaft. The sleeve portion is provided with a top wall. The oil seal is arranged inside the sleeve portion, and the oil seal abuts upward against the top wall. By providing the sleeve portion, the oil seal can be more conveniently and reliably positioned, and the structure is simple and the assembly is convenient.

[0008] Further, the oil seal includes a body portion and a sealing rib protruding upward from the body portion. The sealing rib abuts upward against the top wall. By providing the sealing rib abutting upward against the top wall, the sealing effect between the oil seal and the chassis is better.

[0009] Further, there is a gap between the body portion and the top wall. Since there is a gap between the body portion and the top wall, during the operation of the food processor, the wear on the oil seal can be reduced, so that the sealing performance is better.

[0010] Further, the food processor includes a bracket fitted and installed with the mixing cup. The chassis is clamped between the mixing cup and the bracket, and the motor is installed on the bracket. In this way, the chassis can be fixed conveniently and reliably, and at the same time the motor is installed on the bracket, and the structure is simpler and the assembly is more convenient.

[0011] Further, the bracket and the mixing cup are assembled together by a snap button or a threaded structure. In this way, by rotating the bracket relative to the mixing cup, the chassis can be clamped between the two, and the operation is simple and the structure is reliable.

[0012] Further, the food processor includes a motor cover surrounding the motor. The motor includes a mounting hole provided in the main body portion. The bracket includes a stud passing through the mounting hole. The motor cover is fixed to the stud by a fastener. By providing the motor cover, the noise generated during the operation of the motor can be reduced. Since the bracket includes a stud passing through the mounting hole and the motor cover is fixed to the stud by a fastener, the motor cover can be stably fixed, and the overall structure is simple and reliable.

[0013] Further, the motor includes a shock pad provided in the mounting hole, and the bracket and the motor cover clamp the shock pad. By providing the shock pad, the vibration generated during the operation of the motor is smaller, and further the wear on the oil seal is smaller, so that better sealing performance and stability are obtained.

[0019] Please refer to Figures 1 to 3 , the cooking machine 100 can be used to crush ingredients such as grains, vegetables, and fruits. The cooking machine 100 includes a mixing cup 10, a chassis 20, a motor 30, and a mixing blade 40. The chassis 20 is fixed to the bottom of the mixing cup 10. The motor 30 includes a main body portion 32 and an output shaft 31. The output shaft 31 passes through the chassis 20, and the mixing blade 40 is disposed at the top of the output shaft 31. The mixing cup 10 is used to hold ingredients, and the mixing blade 40 is used to stir and crush the ingredients.

[0020] A seal is formed between the output shaft 31 and the chassis 20 through an oil seal 29. The output shaft 31 is provided with a bushing 33. The bushing 33 presses downward against the main body portion 32, and the bushing 33 presses the oil seal 29 upward against the chassis 20.

[0021] Since both ends of the bushing 33 are respectively pressed against the main body part 32 of the motor and the oil seal 29, the vibration generated during the operation of the motor 30 can be transmitted to the oil seal 29 through the bushing 33, so that the oil seal 29 vibrates together with the main body part 32 of the motor 30, thereby avoiding the motor 30 from squeezing the oil seal 29 and further causing wear to the oil seal 29. In this way, the wear of the oil seal 29 can be reduced, the sealing performance between the output shaft 31 and the chassis 20 can be made more reliable, and thus it can effectively prevent the cooking machine 100 from leaking water during use.

[0022] In the illustrated embodiment, the output shaft 31 is further provided with a corrugated gasket 34, and the corrugated gasket 34 is arranged between the bushing 33 and the oil seal 29. Since the corrugated gasket 34 has good elastic force, it can avoid the corrugated gasket 34 from causing excessive wear to the oil seal 29, thereby ensuring that the oil seal 29 has good sealing performance.

[0023] The bushing 33 is provided with an upwardly protruding annular rib 331, and the corrugated gasket 34 is sleeved outside the rib 331. In this way, through the cooperation of the rib 331 and the corrugated gasket 34, the bushing 33 can more reliably drive the corrugated gasket 34 to vibrate through the rib 331, and then drive the oil seal 29 to vibrate together. In this way, the wear on the oil seal 29 is smaller and the sealing performance is more stable.

[0024] In the illustrated embodiment, the chassis 20 is provided with a sleeve portion 21 surrounding the output shaft 31. The sleeve portion 21 is provided with a top wall 22.

[0025] The oil seal 29 includes a body portion 291 and a sealing rib 292 protruding upward from the body portion 291. The sealing rib 292 is pressed upward against the top wall 22. By providing the sealing rib 292 that is pressed upward against the top wall 22, the sealing effect between the oil seal 29 and the chassis 20 is better. The oil seal 29 includes one, two or three sealing ribs 292, and the sealing ribs 292 are annular.

[0026] There is a gap between the body portion 291 and the top wall 22. Since there is a gap between the body portion 291 and the top wall 22, during the operation of the cooking machine 100, the wear on the oil seal 29 can be reduced, thereby making the sealing performance better.

[0028] The bracket 50 and the mixing cup 10 are assembled together by a snap or thread structure. In this way, by rotating the bracket 50 relative to the mixing cup 10, the chassis 20 can be clamped between the two, and the operation is simple and the structure is reliable. In the illustrated embodiment, a first snap 55 is provided on the inner side of the bracket 50, and a second snap 15 that cooperates with the first snap 55 is provided on the outer side of the mixing cup 10.

[0029] The cooking machine 100 includes a motor cover 60 surrounding the motor 30. The motor 30 includes a mounting hole 37 provided in the main body portion 32. The bracket 50 includes a stud 51 passing through the mounting hole 37, and the motor cover 60 is fixed to the stud 51 by a fastener. By providing the motor cover 60, the noise generated when the motor 30 operates is reduced. Since the bracket 50 includes a stud 51 passing through the mounting hole 37 and the motor cover 60 is fixed to the stud 51 by a fastener, the motor cover 60 can be stably fixed, and the overall structure is simple and reliable. The cooking machine 100 further includes a bottom case 58, and the bottom case 58 is assembled in cooperation with the bracket 50.

[0030] The motor 30 includes a shock pad 35 provided in the mounting hole 37, and the shock pad 35 is clamped by the bracket 50 and the motor cover 60. By providing the shock pad 35, the vibration generated when the motor 30 operates is smaller, and further the wear on the oil seal 29 is smaller, so that it has better sealing performance and stability.
