DETAILED DESCRIPTION

[0025] The utility model is further described below in conjunction with the accompanying drawings.

[0026] The low-noise food processor of the utility model is Figures 1 to 5As shown, the stirring cup assembly 2 includes a stirring cup body 21, a stirring blade 24 and a motor assembly 25. The stirring blade 24 is arranged in the stirring cup body 21. Specifically, the stirring blade 24 is located in the lower part of the stirring cup body 21. The motor assembly 25 drives the stirring blade 24 to rotate, so that the stirring blade 24 can chop the food mixed in the liquid when rotating. Figure 1 and Figure 2 As shown, the blending cup assembly 2 includes a heating base 23 and a plate frame 26. The heating base 23 is used to heat the liquid in the blending cup body 21. Figure 6 As shown, the lower side of the heating chassis 23 is integrally connected with a heating pipe 231, and the heating pipe 231 is arc-shaped; Fig. 9 As shown, the motor assembly 25 includes an output shaft 251 and a motor housing 252. Figure 1 and Figure 2 As shown, the motor housing 252 is fixedly connected to the rack 26, and the stirring blade 24 is relatively fixedly installed on the upper end of the output shaft 251. For example, Figure 2 As shown, a threaded hole is formed at the upper end of the output shaft 251, and a screw is used to pass through the mixing blade 24 from top to bottom and connect with the threaded hole, so that the mixing blade 24 is coaxially fixed to the output shaft 251. Figure 2 As shown, the heating base 23 is arranged on the upper side of the plate frame 26, and the heating base 23 is fixedly installed and connected to the plate frame 26. The lower end of the stirring cup body 21 is formed with an inner flange 211, and the material of the stirring cup body 21 is glass. Figure 6 As shown, the heat generating bottom plate 23 is formed with a plate edge 2301, such as Figure 2 As shown, the inner flange 211 is sandwiched between the plate edge 2301 and the plate frame 26, so that the heating base 23, the plate frame 26 and the mixing cup body 21 are firmly assembled into a whole, and because the motor housing 252 is fixedly installed and connected to the plate frame 26, the motor assembly 25 can be reliably fixed. Figure 7 As shown, the bottom of the tray frame 26 is formed with a lower convex frame 263, as shown in FIG. Fig. 9 As shown, the motor assembly 25 is provided with a rotating support plate 256. Figure 2 As shown, the rotating support plate 256 is adapted to be disposed in the lower convex frame 263, as shown in FIG. Fig. 9 As shown, the output shaft 251 is rotatably connected to the rotating support plate 256. Specifically, the output shaft 251 passes through the rotating support plate 256, and the output shaft 251 is connected to the rotating support plate 256 via corresponding bearings. Figure 2 As shown, the output shaft 251 also passes through the heating base plate 23 and the disc frame 26 , and an oil seal 27 is used to seal the disc frame 26 , the output shaft 251 and the heating base plate 23 .

[0027] like Figure 1 and Figure 2As shown, since the stirring blade 24 is relatively fixedly installed at the upper end of the output shaft 251, it is unnecessary to set a transmission joint structure between the stirring blade 24 and the output shaft 251, thereby eliminating the noise generated during operation due to the setting of the transmission joint structure, and also eliminating the vibration caused by the gap and coaxiality error of the transmission joint structure. In addition, since the heating chassis 23, the motor assembly 25, the plate rack 26 and the stirring cup body 21 are firmly assembled as a whole, the structural rigidity is greatly improved, which is conducive to reducing vibration. More specifically, the plate rack 26 can be a cast aluminum part or a cast steel part; since the rotating support plate 256 is adapted to be arranged in the lower convex frame 263, the output shaft 251 is rotatably connected to the rotating support plate 256, which is conducive to the output shaft 251 to obtain reliable rotation support, so that the vibration of the food processor during operation is greatly reduced, and obvious noise due to vibration is avoided. Therefore, the food processor of the utility model has less noise and lighter vibration during operation.

[0028] Furthermore, if Figure 2 As shown, a shock-absorbing pad frame 2561 is provided between the lower convex frame 263 and the rotating support plate 256. The shock-absorbing pad frame 2561 can be made of rubber. The shock-absorbing pad frame 2561 can include a horizontal part and a vertical part, so that the shock-absorbing pad frame 2561 can be covered on the four sides of the upper end of the rotating support plate 256, so that the shock-absorbing pad frame 2561 has a three-dimensional shock-absorbing effect.

[0029] Furthermore, if Figure 2 As shown, the blending cup assembly 2 includes a sealing ring 28, such as Fig.11 As shown, the outer side of the sealing ring 28 is formed with a ring groove 281. Figure 2 As shown, the inner flange 211 is adapted to be arranged in the annular groove 281, the disk edge 2301 is abutted against the upper side of the sealing ring 28, and the disk frame 26 is abutted against the lower side of the sealing ring 28, thereby avoiding leakage between the disk frame 26 and the inner flange 211 and between the inner flange 211 and the disk edge 2301.

[0030] Furthermore, if Figure 7 As shown, a suspension column 261 is formed on the lower side of the tray frame 26. Fig. 9 As shown, the outer side of the motor housing 252 is formed with a mounting ear 2521. Fig.10 As shown, the mounting ear 2521 is mounted on the lower end of the suspension column 261 by corresponding screws. Specifically, the screws pass upward through the mounting ear 2521 and are coaxially screwed with the suspension column 261, so that the rack 26 hangs and fixes the motor assembly 25. Figure 7 As shown, the tray 26 is formed with a positioning hole 2601. Figure 6As shown, a plug 2302 is formed on the lower side of the heating chassis 23, and the plug 2302 is inserted into the upper end of the positioning hole 2601. The corresponding screw is passed upward through the positioning hole 2601 and screwed to the corresponding plug 2302, so that the heating chassis 23 and the disc frame 26 are relatively fixed, and the inner flange 211 of the mixing cup body 21 is pressed.

[0031] Furthermore, if Fig. 9 As shown, the motor assembly 25 includes a connecting piece 254, one end of which is fixedly connected to the rotating support plate 256. Specifically, one end of the connecting piece 254 is mounted on the upper end surface of the iron core of the stator 253 by a corresponding screw, and the left and right ends of the rotating support plate 256 are respectively welded with foot plates, which are clamped between the upper end surface of the iron core of the stator 253 and the connecting piece 254, so that the connecting piece 254, the iron core of the stator 253 and the rotating support plate 256 are rigidly connected as a whole, and a shock absorbing washer 255 is provided on the mounting ear 2521, as shown in FIG. Fig.10 As shown, the suspension column 261 passes through the shock absorbing washer 255. Fig. 9 As shown, the other end of the connecting piece 254 is attached to the shock absorbing washer 255. Figure 7 As shown, a pressing sheet 2611 is formed on the outer side of the hanging column 261. Fig.10 As shown, the pressing piece 2611 is abutted against the upper side of the shock-absorbing washer 255, so that the motor housing 252 and the disc rack 26 are rigidly connected, and the rotating support plate 256 and the disc rack 26 are weakly floatingly connected. Therefore, when the output shaft 251 vibrates due to the mixing knife 24 cutting solid food, the shock-absorbing washer 255 can absorb the vibration. Since the iron core of the stator 253 is rigidly connected to the rotating support plate 256 as a whole, radial displacement of the axis of the output shaft 251 and the stator 253 is avoided, which is conducive to the normal operation of the motor assembly 25.

[0032] Furthermore, if Figure 1 and Figure 4 As shown, the blending cup assembly 2 includes a bottom cover 22, the upper end of the bottom cover 22 is in close contact with the lower end of the blending cup body 21, and the motor assembly 25 is disposed in the bottom cover 22. Figure 8 As shown, a support column 221 is formed in the bottom of the bottom cover 22. Figure 7 As shown, the lower side of the rack 26 is formed with a mounting post 262. Figure 2 As shown, the lower end of the mounting column 262 is fixedly mounted and connected to the upper end of the supporting column 221 by corresponding screws, so that the bottom cover 22 plays a sound insulation role for the motor assembly 25 .

[0033] Furthermore, if Figure 1 and Figure 3 As shown, the food processor of the present invention further comprises a base 1, such as Figure 4 As shown, a pelvic cavity 11 is formed in the base 1. Figure 1 As shown, the bottom cover 22 is adapted to be placed in the pelvic cavity 11, as shown in FIG. Figure 1 , Figure 3 and Figure 4 As shown, the outer cover of the mixing cup body 21 is provided with a soundproof cover 3, the lower end of the soundproof cover 3 is placed on the base 1, and the soundproof cover 3 can be a transparent injection molded part, such as Figure 4 As shown, a socket 111 is provided at the bottom of the pelvic cavity 11. Figure 5 As shown, a plug 2201 is provided at the bottom of the bottom cover 22. When the bottom cover 22 is placed in the basin 11, the plug 2201 is aligned with the socket 111 to achieve power supply. By providing the soundproof cover 3 and the base 1, the noise is further blocked from being transmitted, which is conducive to reducing the noise generated by the food processor when it is working.
