[0030] This embodiment discloses a partitioned waterproof structure. Figure 1 It is a schematic diagram of the interior of the container cover body according to an embodiment of the utility model. Figure 2 Schematic diagram of the exterior of the container cover of the utility model embodiment. Figure 1 , Figure 2 As shown, the partitioned waterproof structure is arranged at the bottom of the container cover 1. Figure 3 This is a schematic diagram of the micro switch assembly installed on the container cover in the embodiment of the utility model. Figure 3 A micro switch assembly 2 is also installed at the bottom of the container cover 1. The partition waterproof structure includes a convex rib 3. The convex rib 3 protrudes toward the inner side of the bottom of the container cover 1. The convex rib 3 divides the bottom of the container cover 1 into multiple isolation areas, and a drainage hole is provided in each isolation area. The micro switch assembly 2 is fixed in an isolation area and is located on the outer side of the bottom of the container cover 1.
[0031] In this embodiment, the bottom of the container cover 1 is divided into multiple isolation areas by the convex rib 3, and the micro switch assembly 2 is installed in one of the isolation areas, and each isolation area has an independent drainage hole. When water overflows inside the container cover 1, the convex rib 3 will block the water in other isolation areas, so that the possibility of the micro switch assembly 2 being soaked by water is reduced. In addition, each isolation area is provided with an independent drainage hole, and the water will flow away as quickly as possible, so that the micro switch assembly 2 can be effectively waterproofed.
[0032] On the outer side of the bottom of the container cover 1, the position of the rib 3 is a groove 4. If water overflows from the bottom of the inner wall of the container cover 1 and flows to the bottom of the outer wall of the container cover 1, the water will flow along the groove 4 due to the tension, and the water can also be prevented from affecting the micro switch assembly 2 installed on the outer side of the bottom of the container cover 1, effectively protecting the micro switch assembly 2.
[0033] The number of isolation areas and drainage holes can be multiple as needed. In this embodiment, the isolation area includes a first area 5 and a second area 6. A first drainage hole 7 is provided in the first area 5. A second drainage hole 8 is provided in the second area 6. The micro switch assembly 2 is fixed to the second area 6.
[0034] A micro switch trigger hole 9 is provided at the center of the bottom of the container cover 1. Specifically, the convex rib 3 includes a first convex rib segment 301 and a second convex rib segment 302. The edge of the micro switch trigger hole 9, the bottom edge of the container cover 1, the first convex rib segment 301 and the second convex rib segment 302 form a second area 6 at the bottom of the container cover 1. The other area of the bottom of the container cover 1 excluding the second area 6 is the first area 5.
[0035] A first drainage hole 7 is provided in the first area 5. When water flows in from the inner wall of the container cover 1, if it flows into the first area 5, it will be completely discharged through the first drainage hole 7, effectively protecting the micro switch trigger hole 9 installed in the second area 6. The first end of the first rib section 301 extends to the bottom edge of the container cover 1, and a second drainage hole 8 is provided between the second end of the first rib section 301 and the edge of the micro switch trigger hole 9. The second drainage hole 8 is provided at the end edge of the first rib section 301, so when water overflows to the second area 6 of the outer wall of the container cover 1, the water can be discharged as quickly as possible through the second drainage hole 8.
[0036] This embodiment also discloses an optional specific structure and installation method of the micro switch assembly 2. Figure 4 Schematic diagram of a micro switch assembly in an embodiment of the utility model. Figure 5 FIG. 2 is a schematic diagram of a micro switch assembly from another angle in an embodiment of the present utility model. Figure 4 , Figure 5As shown, the micro switch assembly 2 includes a fixing seat 203, and a second fixing hole 204 is provided on the fixing seat 203. The lever assembly 201 is mounted on the fixing seat 203 to trigger the micro switch 202. Further, the fixing seat 203 is also provided with a fixing sheet 205 protruding toward the bottom of the fixing seat 203.
[0037] Combination Figure 1 , Figure 2 The second area 6 is provided with a first fixing hole 10 and a limiting hole 11, the fixing sheet 205 is inserted into the limiting hole 11 to position the fixing seat 203, and the fixing member passes through the second fixing hole 204 to fix the fixing seat 203 to the position of the first fixing hole 10 on the outer side of the bottom of the container cover body 1. The fixing member can be a screw or the like.
[0038] Furthermore, in order to increase the waterproof effect, a flange structure protruding toward the inner side surface of the bottom of the container cover 1 is arranged around the first fixing hole 10 and the limiting hole 11. When water enters the second area 6, it can effectively prevent water from penetrating into the micro switch assembly 2 at the bottom of the second area 6, so that the water is discharged from the second drainage hole 8 first.
[0039] Figure 6 for Figure 3 This is a schematic diagram of another angle of the micro switch assembly installed on the container cover in the embodiment of the utility model. Figure 6 and Figure 3 A micro switch trigger hole 9 is opened at the bottom of the container cover body 1, and the action end of the lever assembly 201 extends to the micro switch trigger hole 9, and the trigger end of the lever assembly 201 is used to contact the micro switch 202.
[0040] This embodiment also discloses a kitchen appliance provided with the above partitioned waterproof structure. Figure 7 It is a cross-sectional view of the kitchenware in the embodiment of the present utility model. Figure 8 This is a cross-sectional view of the micro switch assembly installed on the container cover in the embodiment of the utility model. Figure 7 , Figure 8 As shown, the kitchenware includes a container cover 1 and a container liner 12 assembled inside the container cover 1. A micro switch assembly 2 is fixed to the outer side of the bottom of the container cover 1. A trigger structure 14 is provided at the bottom of the container liner 12. When the container liner 12 is installed on the container cover 1, the trigger structure 14 contacts the trigger end of the micro switch assembly 2 through the micro switch trigger hole 9 opened at the bottom of the container cover 1, and the micro switch 202 is turned on, so that operations such as automatic startup or automatic heating can be performed. A heating plate 13 is also fixed to the bottom of the container liner 12, and the heating plate 13 is in the space between the bottom of the container liner 12 and the container cover 1. The container cover 1 can also provide a heat preservation function for the container liner 12.
[0041] When water flows in from between the outer wall of the container liner 12 and the inner wall of the container cover 1, the water will flow to the bottom of the container cover 1, and the first area 5 and the second area 6 will be separated by the convex rib 3 at the bottom of the container cover 1. The first area 5 has an independent first drainage hole 7, and the second area 6 has an independent second drainage hole 8. When water flows into the first area 5, it will be completely discharged through the first drainage hole 7, effectively protecting the micro switch assembly 2 installed at the bottom of the second area 6. When water flows into the second area 6, the water will pass through the first fixing hole 10 and the limiting hole 11 of the second area 6. Since the first fixing hole 10 and the limiting hole 11 are both provided with a flange structure, and the second area 6 is provided with the second drainage hole 8, water can be blocked from flowing into the installation position of the micro switch assembly 2, and at the same time, water can be quickly retained through the second drainage hole 8 to protect the micro switch assembly 2 installed at the bottom of the second area 6.
[0042] When water overflows to the bottom of the outer wall of the container cover 1 through the micro switch trigger hole 9 at the bottom of the inner wall of the container cover 1, the groove 4 at the reverse side of the rib 3 will effectively isolate the overflowed water and protect the micro switch assembly 2.
[0043] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0044] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
