Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of cooking equipment, especially to a microwave oven anti-overflow motor support and cooking device. BACKGROUND

[0002] As an indispensable electrical equipment in modern kitchen, microwave ovens are favored by consumers for their high heating efficiency and convenience. Among various structures of microwave ovens, the turntable type is widely used because it can achieve uniform absorption of microwaves by food. The traditional turntable type of microwave ovens usually adopts a turntable motor at the bottom of the cavity to drive the glass plate inside the cavity to rotate uniformly through a connector, thereby ensuring uniform heating of food during the heating process and improving the heating efficiency and effect.

[0003] During the use of the microwave oven, water may accumulate inside the cavity due to steam generated during the heating process of food or residual water in the cavity not completely removed by the user before use. If the accumulated water is not promptly drained, it may adversely affect the normal operation of the microwave oven. In particular, when the accumulated water comes into contact with the turntable motor, it may cause damage to the motor, thereby affecting the overall performance and service life of the microwave oven.

[0004] To prevent the accumulated water from flowing from the inside of the cavity to the turntable motor, the existing technology usually adds a surrounding rib and a drainage hole to the turntable motor support of the cavity assembly. The surrounding rib is designed to block the accumulated water from flowing directly to the turntable motor, while the drainage hole is used to guide the accumulated water out of the cavity, thereby ensuring a dry working environment for the turntable motor and preventing the motor from being damaged by water.

[0005] However, the current commonly used turntable motor support structure has the following problems in actual application:

[0006] Firstly, the design of the surrounding rib is often incomplete, with missing parts. These missing parts may allow the accumulated water to flow out along the gaps of the surrounding rib and flow to the turntable motor along the positioning holes of the motor support. Once the accumulated water comes into contact with the turntable motor, it may cause internal short circuit or corrosion of the motor, thereby damaging the motor and affecting the normal operation of the microwave oven.

[0007] Secondly, the design of the drainage hole of the existing turntable motor support also has deficiencies. Many drainage holes lack effective guiding structures, resulting in a lack of clear guidance for the accumulated water during the flow-out process. In this case, part of the accumulated water may flow to the turntable motor along the stretching wall at the bottom of the motor support, also causing damage to the motor. In addition, the size and position design of the drainage hole may not be reasonable enough to ensure that the accumulated water can be quickly and completely drained out of the cavity, thereby increasing the risk of the accumulated water threatening the turntable motor.

[0008] A microwave oven with improved water drainage structure is disclosed in Chinese patent CN1217451A, which has a water collecting groove at a water collecting part of the cooking chamber bottom plate, and one or more than one first water drainage hole on the water collecting groove, and a downwardly inclined section at the lower part of the motor bracket than the first water drainage hole for preventing water dripping from the first water drainage hole from flowing into the motor. There is one or more than one second water drainage hole at one end of the downwardly inclined section of the motor bracket. However, this solution needs to make structural improvement to the cooking chamber bottom plate, and for microwave ovens with different sizes, shapes or powers, the water drainage structure needs to be redesigned to meet the specific requirements, which not only increases the manufacturing cost, but also improves the production complexity.

[0041] Bottom plate 1, set up motor mounting portion 4 on it, for installing carousel motor 11, carousel motor 11's output shaft is from below and upwards and stretches out bottom plate 1 through motor mounting hole 5;

[0042] Side wall 2, set up in the outer edge of bottom plate 1 and bend to one side;

[0043] Wherein, set up the surrounding muscle 6 on the bottom plate 1 around the motor mounting hole 5, the surrounding muscle 6 is used to form the closed surrounding structure of the circumferential outside of motor mounting hole 5, set up the first drain hole 7 on the bottom plate 1 inside the surrounding structure, set up the second drain hole 9 on the bottom plate 1 outside the surrounding structure. As preferred, the microwave oven anti -overflow water motor support further includes connecting flanging 3, the connecting flanging 3 is set up in the side wall 2 away from the bottom plate 1 side, for connecting chamber bottom plate 16.

[0044] The microwave oven anti -overflow water motor support disclosed in the application, through further optimization design of the motor support structure including bottom plate 1, side wall 2 and connecting flanging 3, by setting surrounding muscle 6 on the bottom plate 1 around the motor mounting hole 5, the surrounding muscle can be designed in a closed manner, or connected with the side wall to form a closed surrounding structure, thereby forming a relatively closed protective barrier around the motor mounting hole 5, so that when the accumulated water in the microwave oven chamber 400 flows to the motor support 12, by improving the structure of the surrounding muscle 6, the diffusion of water is further limited, the water storage capacity of the motor support 12 is increased, and the water discharge capacity of the drain hole of the motor support 12 is greater than the inflow capacity of the water into the motor support, the water flow into the motor support 12 is mainly discharged outward through the second drain hole 9 outside the surrounding structure, and the first drain hole 7 is arranged on the bottom plate 1 inside the surrounding structure, so that even if water overflows, it can also be quickly discharged through the drain hole, avoiding the accumulation of water near the motor, ensuring that water does not flow to the surrounding of the motor, thereby effectively protecting the motor from water damage, ensuring the normal operation of the microwave oven and prolonging the service life of the motor.

[0045] The microwave oven anti -overflow water motor support, through the design of surrounding muscle and double drain holes, significantly improves the waterproof performance of the microwave oven and the protection effect of the motor, the closed design of the surrounding muscle 6 not only forms a protective barrier, but also limits the diffusion of water, increases the water storage capacity of the motor support 12, ensures the drainage efficiency, and further reduces the risk of water accumulation in combination with the design of double drain holes, ensures that the environment around the microwave oven motor mounting hole 5 remains dry during use, prolongs the service life of the motor, improves the reliability and durability of the microwave oven, and brings better user experience.

[0046] As a preferred example of the present application, a flow guide surface 8 is arranged on the bottom plate 1 between the motor mounting hole 5 and the first drainage hole 7, and the elevation of the position of the side of the flow guide surface 8 close to the first drainage hole 7 is lower than the elevation of the position of the side of the flow guide surface 8 close to the motor mounting hole 5. This arrangement sets up a flow guide surface 8 between the motor mounting hole 5 and the first drainage hole 7, and the flow guide surface 8 has an inclined design, with the side close to the first drainage hole 7 being lower in height than the side close to the motor mounting hole 5. This design allows water to flow naturally along the inclined direction of the flow guide surface 8 when water accumulates in the surrounding reinforcement 6, thereby effectively guiding the water flow from the vicinity of the motor mounting hole 5 to the first drainage hole 7 and outwards, and the presence of the flow guide surface 8 not only accelerates the guiding process of the water, but also ensures that the water can be quickly and smoothly drained, avoiding stagnation and accumulation in the area around the motor, and further improving the waterproof performance of the motor support.

[0047] This design optimizes the flow path of the water, improves the drainage efficiency, and allows the water to be drained more quickly and completely from the motor support 12, reducing the residence time of the water near the motor, thereby effectively reducing the potential threat of the water to the motor. In addition, while increasing the flow guide surface 8 between the motor mounting hole 5 and the first drainage hole 7 for flow guidance, sufficient consideration is also given to the safety distance between the first drainage hole 7 and the turntable motor, to ensure that the liquid flowing out of the first drainage hole 7 does not affect the normal operation of the turntable motor, avoiding the situation where the liquid flows along the bottom of the turntable motor support to the turntable motor, thereby further improving the safety and reliability of the microwave oven, and providing users with a more reassuring use experience.

[0048] As a preferred example of the present application, the surrounding reinforcement 6 is designed in a closed manner, or the surrounding reinforcement 6 is connected with the side wall 2 to form a closed enclosing structure. By further optimizing the structure of the surrounding reinforcement 6, the surrounding reinforcement 6 is designed in a closed manner or connected with the side wall 2 to form a closed enclosing structure, which surrounds the motor mounting hole 5 and builds a complete protective barrier, not only enhancing the structural strength of the motor support, but also greatly improving its water blocking ability, effectively preventing the water from directly contacting the motor, while guiding the water to flow along the predetermined path, thereby effectively protecting the motor from water damage.

[0049] As a preferred example of the present application, the surrounding rib 6 comprises a first rib part 601 and two second rib parts 602, the first rib part 601 is arranged in a circular arc shape concentrically outside the circumference of the motor mounting hole 5, and the second rib part 602 is connected to the first rib part 601 at one end and connected to the side wall 2 at the other end. As a preferred example, the two second rib parts 602 are designed in a splayed shape from the side close to the first rib part 601 to the side close to the side wall 2, and the two second rib parts 602 are arranged symmetrically along the line connecting the center of the first drain hole 7 to the center of the motor mounting hole 5. This arrangement discloses a specific structure of the surrounding rib 6, which is composed of a first rib part 601 and two second rib parts 602, wherein the first rib part 601 is arranged in a circular arc shape concentrically outside the circumference of the motor mounting hole 5 to provide preliminary protection for the motor; the two second rib parts 602 are connected to the first rib part 601 at one end and connected to the side wall 2 at the other end, forming an enhanced connection structure, and the two second rib parts 602 are designed in a splayed shape from the side close to the first rib part to the side wall, so that the coverage area of the surrounding rib is increased, and at the same time, the water is guided to disperse to both sides, reducing the possibility of water flowing directly to the motor. When water flows into the motor support, the surrounding rib structure effectively limits the spread of water, accelerates the flow of water to the drain hole, ensures that water can be quickly guided and discharged, thereby avoiding accumulation near the motor and ensuring normal operation of the motor.

[0050] The present application also discloses a cooking device, comprising a main body structure 100, a cavity 400 is arranged on the main body structure 100, a door assembly 200 capable of opening or blocking the cavity 400 is arranged at the front end of the cavity 400, a panel assembly 300 is arranged on the main body structure 100 at one side of the cavity 400, a turntable assembly 500 is arranged in the cavity 400, the turntable assembly 500 can rotate under the action of a motor drive device, and the motor drive device comprises a turntable motor 11 and a microwave oven anti-water overflow motor support as described in the above embodiment.
