Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a food processor. Background Art

[0002] During the use of food processors such as wall breakers, soybean milk machines, cooking machines, and grinders, the motor is in a high-speed rotation state, resulting in relatively large vibrations and easy generation of noise, thus causing inconvenience in use; moreover, the temperature inside the motor will also increase with the increase of the use time. If the heat dissipation performance of the motor installation cavity is poor, the temperature inside the motor will be too high, causing the motor to burn out due to overheating, seriously affecting the service life of the product.

[0003] To overcome the noise problem and temperature rise problem existing during the operation of the motor, generally, a sound insulation cover is used for partial sound insulation. Although it can maintain a certain heat dissipation performance, the sound insulation effect is not good, and most of the noise will still spread to the outside of the main body along with the air flow, bringing a very bad experience to users; the full-enclosure technology of the motor bracket can also be used, and its sound insulation effect is improved to a certain extent, but the assembly process is extremely complex. If the assembly error is too large, it is very easy to cause vibration noise caused by poor concentricity, making the noise more obvious, and its heat dissipation effect is also poor.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this utility model belongs. The terms used in the description of this utility model are only for describing specific embodiments and are not intended to limit this utility model.

[0040] According to Figures 1 to 10 As shown, an embodiment of a food processor provided by this utility model includes: a motor 1, a wind cover 2, a housing 3, a bottom shell 4, and a bottom cover 6.

[0041] Specifically, a wind blade 11 is provided at the output end of the motor 1; a first socket wall 22 is provided on one opposite side of the wind cover 2, and a wind blade opening 21 corresponding to the wind blade 11 is provided on the other opposite side. The motor 1 is installed inside the wind cover 2 and a heat dissipation space 20 is formed between the motor 1 and the inner wall of the wind cover 2; a socket platform 312 is provided on the housing 3 corresponding to the first socket wall 22. The housing 3 and the wind cover 2 are assembled with each other so that the socket platform 312 cooperates with the first socket wall 22. An air passage space 30 is formed between the housing 3 and the wind cover 2. A first air duct 101 is formed between the socket platform 312 and the first socket wall 22. A third air duct 103 is formed between the edge of the first socket wall 22 and the housing 3. The first air duct 101 and the third air duct 103 form a bent transition. In practice, the first air duct 101 and the third air duct 103 are arranged perpendicular to each other; the bottom shell 4 is connected to the housing 3. A wind blade hole 400 is provided on the bottom shell 4 corresponding to the wind blade opening 21. An air inlet hole 41 communicating with the air passage space 30 is provided on the bottom shell 4. The wind blade 11 sequentially passes through the wind blade opening 21 and the wind blade hole 400; the bottom cover 6 is installed on the bottom shell 4 corresponding to the wind blade hole 400. An air outlet hole 61 communicating with the wind blade hole 400 is provided on the bottom cover 6; the air inlet hole 41, the air passage space 30, the third air duct 103, the first air duct 101, the heat dissipation space 20, the wind blade opening 21, the wind blade hole 400, and the air outlet hole 61 are sequentially communicated.

[0042] Through the above settings, the noise generated by the motor 1 is blocked by the wind cover 2 and the socket platform 312 when passing through the first air duct 101 and the third air duct 103, so that the noise is weakened, and the air flow can enter the heat dissipation space 20 from the third air duct 103 and the first air duct 101, and then be discharged from the air outlet hole 61 under the action of the wind blade 11. Thus, the sound insulation performance and ventilation performance of the first air duct 101 and the third air duct 103 are utilized, and at the same time, noise reduction and heat dissipation of the motor 1 are achieved, and the assembly is simpler to avoid vibration noise caused by assembly errors.

[0043] Specifically, the wind cover 2 is further provided with a second socket wall 23, which is arranged on the side of the first socket wall 22 facing the wind blade opening 21, and the diameter length of the second socket wall 23 is smaller than that of the first socket wall 22; in addition, a noise reduction rib 314 is arranged at the end of the socket table 312, and a second air duct 102 is formed between the edge of the second socket wall 23 and the end of the socket table 312. Optionally, a fourth air duct 104 is formed between the second socket wall 23 and the noise reduction rib 314, and the second air duct 102 and the fourth air duct 104 form a bent transition. Further, the second air duct 102 and the fourth air duct 104 are arranged perpendicular to each other; wherein, the first air duct 101 and the second air duct 102 also form a bent transition. Further, the first air duct 101 and the second air duct 102 are also arranged perpendicular to each other, thereby forming multiple bent sound insulation layers to more completely block the noise. The ranges of the width L1 of the first air duct 101, the width L2 of the second air duct 102, and the width L3 of the third air duct 103 are all 1-4 mm. Because when the width of the air duct is less than 1 mm, the air intake will be affected, resulting in poor heat dissipation effect, and when the width of the air duct is greater than 4 mm, the blocking effect on high-frequency noise is poor; the air intake hole 41, the air passing space 30, the third air duct 103, the first air duct 101, the second air duct 102, the fourth air duct 104, the heat dissipation space 20, the wind blade opening 21, the wind blade hole 400, and the air outlet hole 61 are connected in sequence. Correspondingly, as Figure 4 shown, the air flow also passes through the above-mentioned structures in sequence to take away the heat dissipated by the motor 1 in the heat dissipation space 20, playing a role in heat dissipation; more specifically, the housing 3 is provided with a ring rib 313 corresponding to the peripheral edge of the socket table 312, and the ring rib 313 is arranged around the third air duct 103, playing a further role in blocking noise to enhance the noise reduction effect.

[0044] Further, the wind cover 2 is provided with a fixing hole 25, and the motor 1 is provided with a fixing table 12 corresponding to the fixing hole 25. The motor 1 is installed in the wind cover 2 by connecting the fixing table 12 into the fixing hole 25; optionally, a fixing member 7 can also be used to connect the fixing table 12 and the fixing hole 25, so that the motor 1 is more firmly installed in the wind cover 2; further, the wind cover 2 is also provided with a wire harness groove 24, and the wire of the motor 1 is led out to the outside of the wind cover 2 through the wire harness groove 24, so as to be connected to the power supply in the food processor.

[0045] Actually, the housing 3 includes a housing cover 31 and a housing case 32. A socket table 312 is disposed on the side of the housing cover 31 facing the air hood 2. The housing cover 31, the housing case 32 and the outer peripheral side of the air hood 2 surround to form an air passing space 30. Preferably, a fastening tooth 316 is provided at the edge of the housing cover 31, and a fastening table 321 corresponding to the fastening tooth 316 is provided on the inner wall of the housing case 32. The housing cover 31 is detachably connected to the housing case 32 by fastening the fastening tooth 316 to the fastening table 321. More preferably, the food processor further includes: a panel 5. The housing case 32 is provided with a maintenance opening 320, and the panel 5 is detachably installed at the maintenance opening 320 so that maintenance personnel can perform maintenance on the inside of the food processor by disassembling the panel 5.

The rotating shaft of the motor 1 is installed in the motor port 311 so that both ends of the motor 1 are rotatably installed, ensuring the stable rotation of the motor 1.

[0046] Furthermore, the bottom case 4 is provided with a wind guiding rib 401 corresponding to the wind blade hole 400. The wind guiding rib 401 is disposed on the side of the bottom case 4 facing away from the housing 3 to guide the air flow, thereby forming a more stable and high-speed air flow and achieving better heat dissipation performance. In addition, the housing 3 is provided with a fixing column 315 facing the bottom case 4, and the bottom case 4 is provided with a fixing position 42 corresponding to the fixing column 315.
