[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Figure 1 This is a perspective view of a drainage structure cavity according to this utility model, as shown below. Figure 1 In the illustrated embodiment, this utility model provides a drainage structure, which includes a fan mounting plate 1, which is mounted on a cavity 2. A fan is mounted on the fan mounting plate 1. The fan mounting plate 1 has a through hole 113 for the fan shaft to pass through. The cavity 2 has ventilation holes 4. The fan mounting plate 1 is installed on the outer side of the cavity 2 corresponding to the ventilation holes 4. The fan shaft passes through the through hole 113 and the ventilation holes 4 sequentially, extending into the cavity 2. When there is excessive condensate on the fan mounting plate 1, the condensate will enter the fan through the through hole 113. Therefore, by providing at least one drainage hole 3 on the surface of the cavity 2 corresponding to the position on the fan mounting plate 1, condensate between the fan mounting plate 1 and the outer side of the cavity 2 can be drained into the cavity 2 through the drainage hole 3, preventing it from entering the fan and damaging the fan components, thus extending the fan's service life.

[0021] In one embodiment, the drain hole 3 is located at the lower end of the fan mounting plate 1. The fan shaft is generally located in the middle of the fan mounting plate 1, and the condensate on the fan mounting plate 1 will accumulate between the inner side of the fan mounting plate 1 and the outer side of the cavity 2. Without the drain hole 3, when the height of the condensate reaches the fan shaft, the condensate will enter the fan through the gap between the fan shaft and the through hole 113. In this invention, the drain hole 3 is located at the lower end of the fan mounting plate 1, that is, below the through hole 113, so that the drain hole 3 can drain the condensate in a timely manner.

[0022] In one embodiment, a groove 210 is provided on the outer side of the cavity 2 corresponding to the position of the fan mounting plate 1. A ventilation hole 4 is provided on the bottom surface of the groove 210. The fan mounting plate 1 covers the groove 210, ensuring that condensation occurs on the inner side of the fan mounting plate 1 corresponding to the groove 210. The condensation flows into the groove 210, allowing it to be collected and drained promptly. Specifically, a drain hole 3 is also provided on the bottom surface of the groove 210 to drain the collected condensation. Specifically, the drain hole 3 is located below the ventilation hole 4, facilitating timely and reliable drainage of condensation from the groove 210. Specifically, the groove 210 is formed by a recess in the surface of the cavity 2, moving away from the fan mounting plate 1. Specifically, the ventilation hole 4 is either an air inlet or an air outlet.

[0023] Figure 2 This is a perspective view of a drainage structure of this utility model applied to a microwave steam oven, as shown. Figure 2 In the embodiment shown, it includes a cavity 2 and a fan mounting plate 1. The fan mounting plate 1 is fixed to the cavity 2 at the position corresponding to the groove 210 by bolts. The fan is fixed to the fan mounting plate 1 by bolts. The fan shaft of the fan passes through the through hole 4 and the ventilation hole 4 in sequence and extends into the cavity 2. The blades are installed on the fan shaft.

[0024] As one embodiment, a sealing element 5 is provided on the inner wall of the groove 210 to prevent condensate from flowing out from the gap between the cavity 2 and the fan mounting plate 1. Specifically, the drain hole 3 is located between the sealing element 5 and the ventilation hole 4 to ensure that condensate is discharged from the drain hole 3 and to prevent the sealing element 5 from affecting the discharge of condensate. Specifically, the sealing element 5 is a sealing ring.

[0025] As one embodiment, the fan mounting plate 1 is located on the back or side of the cavity 2.

[0026] Figure 3 This is a front view of a drainage structure fan fixing plate according to this utility model, as shown below. Figure 3In the embodiment shown, in order to facilitate the rapid flow of condensate on the fan mounting plate 1 to the bottom of the fan mounting plate 1, a flow guiding structure 110 is provided on the surface of the fan mounting plate 1 near the cavity 2. This structure guides the condensate to the bottom of the fan mounting plate 1. The flow guiding structure 110 can quickly guide the condensate to the bottom of the fan mounting plate 1, preventing the condensate from accumulating at the fan shaft and entering the fan.

[0027] As one embodiment, the flow guiding structure 110 includes an annular flow guiding groove 111 and at least one flow diversion groove 112. The annular flow guiding groove 111 is distributed along the outer circumference of the fan fixing plate 1. One end of the flow diversion groove 112 is located in the middle of the fan fixing plate 1, and the other end of the flow diversion groove 112 is connected to the annular flow guiding groove 111. The annular flow guiding groove 111 is used to guide the condensate on the outer circumference of the fan fixing plate 1 to the bottom of the fan fixing plate 1, and the flow diversion groove 112 is used to guide the water in the middle position of the fan fixing plate 1 into the annular flow guiding groove 111. Specifically, there are three drainage channels 112, which form an inverted "Y" shape. This allows the condensate at the top of the fan mounting plate 1 to be guided through the drainage channels 112 to the bottom of the annular drainage channel 111. At the same time, the condensate in other parts of the fan mounting plate 1 can also flow into the drainage channels 112 and then be guided through the drainage channels 112 to the bottom of the annular drainage channel 111. This can guide most of the condensate in the fan mounting plate 1 to the bottom of the fan mounting plate 1, resulting in good drainage effect and facilitating rapid discharge through the drain hole 3 into the cavity 2 for evaporation.

[0028] As one embodiment, the through hole 113 is located at the connection point of the three drainage channels 112, so that the condensate around the fan shaft will flow into the drainage channel 112. Specifically, the connection point of the three drainage channels 112 is provided with a protrusion protruding from the bottom surface of the drainage channel 112, and the through hole 113 is provided on the protrusion, so that the condensate in the drainage channel 112 will not flow back to the through hole 113, thus ensuring high reliability.

[0029] Specifically, the annular seal 5 is located on the outer ring of the annular guide groove 111.

[0030] It should be noted that the inner side of the fan mounting plate 1 refers to the side of the fan mounting plate 1 that is close to the cavity 2, and the outer side of the cavity 2 refers to the side of the cavity 2 that is close to the fan mounting plate 1.

[0031] Specifically, the principle of this utility model is that condensation will be generated on the surface of the fan fixing plate 1 near the cavity 2. The condensation will flow into the space between the fan fixing plate 1 and the cavity 2. The water in the space will be discharged into the cavity 2 through the drain hole 3. In this way, the accumulated condensation will not enter the fan, will not damage the fan components, and will extend the service life of the fan.

[0032] Operation process: When the microwave oven is working for a long time, condensation will be generated on the side of the fan mounting plate 1 facing the cooking cavity. The condensation is guided to the bottom of the annular guide groove 111 through the annular guide groove 111 and the guide groove 112, and then flows into the groove 210. Finally, it is discharged into the cavity 2 through the drain hole 3 for evaporation, which avoids water accumulation inside the fan, damage to the fan components, and extends the service life of the fan.

[0033] Based on the above solutions, if any modifications or variations to this utility model do not depart from the spirit and scope of this utility model, and if such modifications and variations fall within the scope of the claims and equivalent technologies of this utility model, then this utility model also intends to include such modifications and variations.
