[0002] To prevent steam leakage from the microwave oven, the fan baffle and the inner liner cover need to be connected by a seal (rubber ring). However, since the seal is exposed to high temperature baking environment for a long time, it will age and crack.

[0003] According to existing technology, there is a combination steam oven, microwave oven, and steam oven, with publication number CN211795854U. The outer edge of the hot air blower baffle is bent towards the back plate to form a baffle. The baffle abuts against the back plate to form an annular mounting cavity. A first sealing element is installed in the annular mounting cavity. An annular water flow channel is formed in the annular mounting cavity along the circumference of the first sealing element. By injecting cold water into the annular water flow channel, the first sealing element can be cooled. The water cooling method is used to cool the sealing element to prevent aging. The structure is complex and the cost is high. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Figure 1 This is a top sectional view of a sealing structure of this utility model applied to a microwave steam oven, as shown below. Figure 1 In the illustrated embodiment, this utility model provides a sealing structure, including a sealing element 1, a cavity 2, and a fan baffle 4. The sealing element 1 is used to achieve a seal between the outer surface of the cavity 2 and the fan baffle 4. Specifically, to prevent the sealing element 1 from aging and cracking, a suspended bracket 3 is provided to suspend the sealing element 1, preventing it from directly contacting the outer surface of the cavity 2. One end of the suspended bracket 3 near the cavity 2 is sealed to the outer surface of the cavity 2, and the other end of the suspended bracket 3 away from the cavity 2 is sealed to the fan baffle 4 through the sealing element 1. The fan is mounted on the fan baffle 4, and the fan shaft of the suspended bracket 3 passes through the fan baffle 4 and the suspended bracket 3 sequentially, extending into the cavity 2.

[0025] Specifically, the suspended bracket 3 is hollow and runs vertically through the cavity, suspending the sealing element 1 outside the cavity 2. The sealing element 1 is installed on the suspended bracket 3 at a position away from the cavity 2. In other words, the suspended bracket 3 is a hollow and vertically open bracket, and the sealing element 1 is installed on the outer circumference of the end of the suspended bracket 3 away from the cavity 2. At the same time, it is lightweight and easy to fix, and the hot air inside the cavity 2 can circulate within the suspended bracket 3 to ensure uniform heat distribution within the cavity 2.

[0026] Specifically, seal 1 is a rubber sealing ring.

[0027] Figure 2 yes Figure 1 An enlarged diagram of A in the diagram is shown below. Figure 2 In the embodiment shown, the suspended bracket 3 has a suspended part 310 at the end away from the cavity 2. The suspended part 310 protrudes from the outer side of the suspended bracket 3, so that there is a large space between the bottom surface of the suspended part 310 and the outer surface of the cavity 2. This makes it easier for the heat of the outer surface of the cavity 2 to dissipate into the air. When the temperature of the outer surface of the cavity 2 is transferred to the seal 1, the temperature is lower, and the seal 1 will not age or crack, resulting in high reliability.

[0028] Figure 3 This is a perspective view of a sealed suspended support structure according to this utility model, as shown below. Figure 3In the shown embodiment, in order to facilitate the installation of the sealing element 1, the overhanging part 310 is provided with an annular installation groove 311 for installing the sealing element 1, and when installed, the outer side surface of the sealing element 1 abuts against the inner side wall of the annular installation groove 311, thereby achieving positioning of the sealing element 1 and facilitating installation.

[0029] Figure 4 is a front view of the connection between the sealing structure, the fan baffle, the sealing element and the overhanging support according to the present application, as shown in Figure 4 In the shown embodiment, the overhanging support 3 is detachably connected with the fan baffle 4. Specifically, the overhanging part 310 is connected with the fan baffle 4 through bolts, which can press the sealing element 1 tightly and ensure the sealing effect between the overhanging support 3 and the fan baffle 4, thereby preventing steam from leaking from the gap between the overhanging support 3 and the fan baffle 4.

[0030] As an embodiment, in combination with Figure 3 and Figure 4 , the overhanging part 310 protrudes from the outer side surface of the overhanging support 3, so that there is sufficient space below the annular installation groove 311, facilitating the bolts to pass through the fan baffle 4 and the overhanging support 3 in turn downwardly, and facilitating installation and dismounting.

[0031] Figure 5 is Figure 4 is an enlarged schematic view of B in Figure 5 In the shown embodiment, in order to facilitate the installation of the fan baffle 4 on the overhanging support 3, the surface of the fan baffle 4 near the end of the overhanging support 3 is provided with an annular positioning groove 410 corresponding to the annular installation groove 311; when the fan baffle 4 and the overhanging support 3 are fixed together, the outer side surface of the overhanging support 3 is located in the annular positioning groove 410, thereby positioning the fan baffle 4 and facilitating the installation of the fan baffle 4 on the overhanging support 3.

[0032] Figure 6 is a perspective view of the sealing element according to the present application, as shown in Figure 6 In the shown embodiment, the upper surface and / or the bottom surface of the sealing element 1 is provided with at least one annular protrusion 110, and the center of the annular protrusion 110 is located on the axis of the sealing element 1. When the upper surface of the sealing element 1 is provided with the annular protrusion 110, the bottom surface of the fan baffle 4 is pressed against the annular protrusion 110, the annular protrusion 110 is pressed on the fan baffle 4, and the contact between the annular protrusion 110 and the surface is equivalent to linear sealing, and the sealing surface of the linear sealing is much smaller than that of surface sealing, which is easier to achieve and has good sealing effect; when the bottom surface of the sealing element 1 is provided with the annular protrusion 110, the annular protrusion 110 is pressed on the bottom surface of the annular installation groove 311, which is also linear sealing and has good sealing effect. Therefore, when the upper surface and the bottom surface of the sealing element 1 are both provided with at least one annular protrusion 110, the sealing effect is good.

[0033] Specifically, the number of annular protrusions 110 is two, and the sealing effect is better.

Specifically, the end of the suspended bracket 3 close to the cavity 2 is welded to the outer surface of the cavity 2, or the end of the suspended bracket 3 close to the cavity 2 is integral with the outer surface of the cavity 2.

[0036] As an embodiment, a limiting groove 210 is arranged on the surface of the cavity 2, and the end of the suspended bracket 3 close to the cavity 2 is sealingly connected to the bottom of the limiting groove 210 to limit the suspended bracket 3 and facilitate the installation of the suspended bracket 3. Specifically, the limiting groove 210 is located on the outer circumference of the ventilation hole 220 (air inlet hole or air outlet hole), and the ventilation hole 220 is used for installing a fan.

[0037] Specifically, the utility model sets the suspended bracket 3, suspends the sealing element 1 by the suspended bracket 3, and the sealing element 3 does not directly contact the surface of the cavity 2, so that the high temperature inside the cavity 2 will not directly transmit to the sealing element 1, and the sealing element 1 will not appear aging and cracking. Setting a suspended bracket 3 can prevent the aging and cracking of the sealing element, and the structure is simple and the cost is low.
