Description

Technical Field

[0001] The utility model relates to the technical field of cooking machines, in particular to a motor sealing structure and a cooking machine using the same. Background Art

[0002] The cooking machine can be used for automatic cooking, freeing the user's hands and preventing the user from inhaling oil smoke, and is therefore popular among users. The cooking machine is driven by a motor to stir and stir the food. The motor is installed in the top cover of the cooking machine. In order to prevent oil and water mist from entering the motor and damaging the motor and the circuit board, a sealing structure needs to be provided between the motor and the top cover. The existing sealing structure is to seal the motor shaft connection end to prevent the part of the motor shaft connected to the stirring blade from being affected by the steam generated when cooking or boiling food. However, the motor is installed on the back of the cover. Although the bottom of the motor shaft is isolated by the sealing structure, the end face of the lead wire at the tail of the motor is still exposed in the cover. Here, after cooking or boiling, a large amount of steam and oil smoke will accumulate at the part where the lower end of the motor shaft is connected to the stirring blade. When the cover is opened, these steam and oil smoke will enter the interior through the notch at the rotating shaft end of the cover. The lead wire at the tail of the motor will be corroded by the steam and oil smoke and the electronic components inside the motor will be damaged after long-term use. Therefore, a motor sealing structure is needed to seal the lead wire part at the tail of the motor.

[0003] The existing patent with announcement number CN110613375B discloses a cooking machine, including a square machine base and a square machine body arranged on the machine base, the top edge of the machine base is provided with a sealing outer wall extending upward, a motor is provided in the machine base, the motor shaft of the motor extends out of the center of the top of the machine base and is connected to a first coupling, the upper end of the machine body is open and the lower end is closed, a cover is provided at the upper end of the machine body, a crushing knife is provided in the machine body, the crushing knife is connected to a crushing knife shaft, the crushing knife shaft extends out of the center of the lower end of the machine body and is connected to a second coupling, a sealing inner wall extending downward is provided at the lower end edge of the machine body, and a sealing inner wall is provided at the bottom of the sealing inner wall. There is a sealed bottom wall, and a hollow sound insulation tube is provided between the sealed bottom wall and the lower end of the body. The sound insulation tube is located outside the second coupling. The sealed bottom wall is provided with a through hole connected to the sound insulation tube. When the body is placed in place on the base, the sealed inner wall extends into and fits the inner surface of the sealed outer wall. The first coupling extends into the sound insulation tube and couples with the second coupling. The sound insulation tube can effectively prevent the transmission noise between the first coupling and the second coupling. The motor in the cooking machine is sealed only at the end of the motor shaft, and the tail wire outlet part of the motor is not sealed, so it is easily damaged by erosion by steam and oil smoke.
