Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of household appliances, specifically, a microwave oven anti -overflow motor support and microwave oven. BACKGROUND

[0002] As an indispensable electrical equipment in modern kitchen, the heating efficiency and convenience of microwave oven are favored by the majority of consumers. As one of the common components of microwave oven, the turntable is usually connected with the motor below the bottom of the cavity through a connector, which is used to place and drive the food to rotate to realize uniform absorption of microwaves and is widely used.

[0003] During the use of the microwave oven, due to the steam generated during the heating of food or the incomplete removal of residual water in the cavity by the user before use, there may be water accumulation in the cavity. If these accumulated water is not discharged in time, it may adversely affect the normal operation of the microwave oven. Especially when the accumulated water contacts the turntable motor, it may cause damage to the motor, thereby affecting the overall performance and service life of the microwave oven.

[0004] Therefore, the Chinese patent with publication number CN208418828U discloses a drainage structure of a microwave oven cavity, which includes an inner container and a motor support located at the bottom of the inner container. The bottom of the motor support is installed with a motor, the bottom of the inner container is provided with a water collecting groove, the motor support is located below the water collecting groove, the first boss of the water collecting groove is provided with a blocking ring and a first drainage hole, and the blocking ring is provided with a circular hole. The first drainage hole is located on the first boss and / or on the blocking ring, and the first drainage hole is located on one side of the circular hole. The bottom wall of the motor support is provided with a second drainage hole, and the lower surface of the part corresponding to the second drainage hole of the bottom wall of the motor support is lower than the upper surface of the motor housing. This scheme can avoid the situation that the accumulated water is not discharged in time and seeps into the motor when there is too much water. However, part of the outflowing water through the drainage hole may also flow along the bottom surface and even seep into the motor, which may also cause damage to the motor.

[0005] Therefore, the present application is proposed. UTILITY MODEL CONTENT

[0006] The problem solved by the utility model is that the existing microwave oven motor support is unreasonable, the overall structure height is high, and in addition, part of the water flows along the bottom wall surface and even seeps into the output shaft, which has a great safety hazard.

[0007] To solve the above problems, this utility model provides a microwave oven anti-overflow motor bracket, including a recessed portion on the base plate, wherein the recessed portion protrudes upward to form a mounting portion for assembling a motor, and the output shaft of the motor extends from the bottom to the top of the motor bracket through a mounting hole; the recessed portion is provided with a first drainage structure, and a baffle rib is provided on the lower outer periphery of the first drainage structure, the baffle rib protruding from the lower bottom surface of the recessed portion.

[0008] This design utilizes the area between the recess and the mounting section to create a water storage space, preventing excessive liquid or even overflow. The first drainage structure allows water to be drained, while the baffle prevents water drained through the first drainage structure from flowing freely down the bottom surface of the recess or even entering the motor. It eliminates the need for multiple stepped structures, increasing the mounting space under the motor bracket and resulting in a lower overall mounting height for the motor bracket, facilitating the installation and fixation of the motor.

[0009] Preferably, the first drainage structure is a drainage hole, and the baffle is annular and located on the outer periphery of the drainage hole. This arrangement can improve the mechanical strength of the drainage hole, extend its service life, and is simple in structure and easy to machine.

[0010] Preferably, the recessed portion further includes a second drainage structure. The first drainage structure and the second drainage structure are spaced apart along the outer periphery of the mounting portion. There are two first drainage structures, which are located on both sides of the second drainage structure. The second drainage structure is an open inclined groove, which faces away from the mounting portion.

[0011] This design places the second drainage structure close to the mounting section. The open sloping groove allows water to drain quickly from the recess, while simultaneously guiding it to a lower position on the groove to prevent free flow along the bottom of the recess towards the output shaft, further reducing safety hazards. By rationally combining the first and second drainage structures, tiered drainage can be achieved. Water entering the area around the mounting section first flows to the nearest second drainage structure and is discharged. When the water volume is large, some water is discharged through the first drainage structure. Because the first and second drainage structures occupy little space and have a low vertical height, sufficient installation space is provided for motor assembly.

[0012] Preferably, the opening inclined groove includes an inclined guide plate, the minimum distance H between the free end of the inclined guide plate and the recess is 1-2 cm, the angle A between the inclined guide plate and the plane where the recess is located is 15-45°, and connecting plates are provided on both sides of the inclined guide plate.

[0013] The setting can further improve the mechanical strength of the opening chute, and guide water away from the output shaft side by using the inclined guide plate, avoid interference with the installation of the motor, and improve the instantaneous drainage capacity of the motor support.

[0014] Preferably, the motor support further comprises a side wall and a connecting flange arranged in connection, the bottom plate portion is recessed downward to form a recess, the side wall is arranged at the outer edge of the bottom plate and is bent to one side, and the connecting flange is arranged at the side of the side wall away from the bottom plate and is used for connecting the bottom of the chamber, and the bottom plate is arranged lower than the connecting flange. The setting can provide assembly space for the output shaft, connector and other components, and further improve the mechanical strength of the motor support.

[0015] Compared with the prior art, the microwave oven anti-overflow motor support has the following advantages: 1) by arranging the first drainage structure and the second drainage structure in the recess, not only the safety hazard of free water flowing along the lower bottom wall in the prior art is eliminated, but also good drainage efficiency is achieved, the risk of water accumulation is further reduced, the dry environment around the microwave oven motor mounting hole is ensured during use, the service life of the motor is prolonged, the reliability and durability of the microwave oven are improved, and better use experience is brought to the user;

[0016] 2) by optimizing the first drainage structure and the second drainage structure, water can be drained from the motor support more quickly and completely, the residence time of water near the motor is reduced, thereby effectively reducing the potential threat of water to the motor; the safety distance of the first drainage structure and the second drainage structure from the motor is fully considered, so that the normal work of the motor is not affected when liquid flows out, the situation that liquid flows along the lower bottom surface of the motor support to the motor is completely avoided, and the use safety and reliability of the microwave oven are further improved.

[0017] The application also provides a cooking device, which comprises a main body structure, a chamber arranged on the main body structure, and a turntable assembly arranged in the chamber, wherein the turntable assembly can rotate under the action of a motor driving device, and the motor driving device comprises a motor and a microwave oven anti-overflow motor support as described above.
