[0064] See also Figures 2 to 7 As shown, in some embodiments, a water inlet 411 may be provided on the inner wall of the water storage cavity. An end of the drain pipe 21 away from the drain port may be connected to the water inlet 411. Therefore, the liquid in the cooking cavity 20 can flow into the water storage cavity through the drain port, the drain pipe 21, and the water inlet 411 in sequence.
[0065] See also Figure 4 and Figure 5 As shown, in some embodiments, the drain pipe 21 can be arranged at an angle. The water inlet 411 of the water storage box 4 can be lower than the drain port of the inner pot 2. In the direction from the drain port to the water inlet 411, the drain pipe 21 can be arranged to extend downward at an angle, so that the end of the drain pipe 21 connected to the drain port is higher than the end of the drain pipe 21 connected to the water inlet 411. When the liquid in the cooking cavity 20 enters the drain pipe 21 through the drain port, the water entering the drain pipe 21 can automatically flow along the drain pipe 21 to the water inlet 411, and flow into the water storage cavity of the water storage box 4 through the water inlet 411, so that the liquid in the cooking cavity 20 can be discharged smoothly.

[0070] See also Figures 3 to 8 As shown, in some embodiments, a water outlet 412 may be provided on the inner wall of the water storage cavity. The cooking device may include a drain pump 5, and a water pumping end of the drain pump 5 may be connected to the water outlet 412. Therefore, the drain pump 5 can extract liquid in the water storage cavity through the water outlet 412.
[0071] See also Figure 8 and Fig. 9 As shown, in some embodiments, a boss portion 413 may be provided in the water storage cavity. The top surface of the boss portion 413 may form a boss surface (not shown in the figure). A drainage area 414 may be formed below the boss surface in the water storage cavity. The water inlet 411 may be provided above the boss surface. Therefore, when the liquid in the cooking cavity 20 enters the water storage cavity through the drain pipe 21 and the water inlet 411, the liquid may automatically flow to the drainage area 414 along the boss surface, so that the liquid automatically gathers in the drainage area 414.
[0072] See also Figure 8 and Fig. 9 As shown, in some embodiments, the drainage area 414 can be formed on one side of the boss portion 413 close to the water outlet 412. The water outlet 412 is connected to the bottom area of the drainage area 414. Therefore, the drainage pump 5 can be used to extract the liquid in the drainage area 414 through the water outlet 412, and all the liquid collected in the drainage area 414 can be discharged from the liquid storage box, effectively ensuring that there is no residual liquid in the water storage cavity, thereby preventing the discharged liquid from affecting the cooking effect of the food.
[0073] See also Figure 8 As shown, in some embodiments, the boss surface may form a first inclined surface (not shown in the figure). The first inclined surface extends downwardly in a direction from the water inlet 411 toward the water outlet 412. Therefore, when the liquid in the cooking cavity 20 enters the water storage cavity through the drain pipe 21 and the water inlet 411, the liquid may automatically flow downwardly along the first inclined surface to the drain area 414 near the water outlet 412.
[0074] See also Figure 8 As shown, in some embodiments, the bottom surface of the water storage chamber may be formed with a second inclined surface (not shown in the figure). The boss portion 413 may be located on the side wall near the top of the second inclined surface. The water outlet 412 may be located on the side wall near the bottom of the second inclined surface. Therefore, the liquid flowing to the bottom of the water storage chamber along the boss portion 413 may automatically flow downward along the second inclined surface to the drainage area 414 near the side of the water outlet 412.
[0075] See also Figure 8 and Fig. 9 As shown, in some embodiments, the water outlet 412 of the water storage cavity can be disposed at the bottom edge of the side wall of the drainage area 414. It should be noted that in other embodiments, the water outlet 412 of the water storage cavity can also be disposed on the bottom surface of the drainage area 414.
[0076] See also Figure 8 and Fig. 9 As shown, in some embodiments, the top edge of the water outlet 412 is lower than the convex surface. Therefore, it can be ensured that there will be no liquid accumulation on the convex surface.
[0077] See also Figures 6 to 9 As shown, in some embodiments, a water outlet pipe 415 may be protruding from the outer wall of the water storage box 4. A water outlet 412 may be formed in the water outlet pipe 415, and the water outlet 412 may be located at the inner end of the water outlet pipe 415. The outer end of the water outlet pipe 415 is connected to the water pumping end of the drainage pump 5. The top of the water outlet pipe 415 is lower than the convex surface, thereby ensuring that no liquid accumulates on the convex surface.
[0078] In some embodiments, a first connecting pipe 51 may be provided between the water pumping end of the drain pump 5 and the outlet pipe 415. The first end of the first connecting pipe 51 may be connected to the water pumping end of the drain pump 5. The second end of the first connecting pipe 51 may be connected to the outer end of the outlet pipe 415. Therefore, the water pump 35 may extract liquid in the drain area 414 through the first connecting pipe 51 and the outlet pipe 415.
[0079] See also Figures 6 to 9As shown, in some embodiments, the first end of the first connecting pipe 51 can be higher than the second end of the first connecting pipe 51, so that the water pumping end of the drainage pump 5 can be higher than the outer end of the outlet pipe 415. Therefore, after the drainage pump 5 stops working, a small amount of residual water can all return to the drainage area 414 through the first connecting pipe 51 and the outlet pipe 415.
[0080] See also Figures 8 to 9 As shown, in some embodiments, a first tube cavity 4151 and a second tube cavity 4152 that are axially connected may be formed in the water outlet pipe 415. An end of the first tube cavity 4151 away from the second tube cavity 4152 may form a water outlet 412, so that the first tube cavity 4151 can be connected to the drainage area 414. An end of the second tube cavity 4152 away from the first tube cavity 4151 is connected to the water pumping end of the drainage pump 5, so that the second tube cavity 4152 can be connected to the water pumping end of the drainage pump 5.
[0081] See also Fig. 9 As shown, in some embodiments, the top side wall of the first tube cavity 4151 may be lower than the top side wall of the second tube cavity 4152, and a step may be formed at the connection between the first tube cavity 4151 and the second tube cavity 4152. Therefore, when the water level in the drainage area 414 is low, the drainage pump 5 can still pump water in the drainage area 414 without pumping in air, so that the drainage area 414 can be pumped more cleanly, effectively ensuring that less liquid accumulates in the water storage cavity.

The baffle 43 may be provided in the first cavity 40a. The water outlet 412 may be located in the second cavity 40b. A water gap 45 may be formed between the dividing rib 44 and the bottom surface of the water storage cavity, and the bottom area of the first cavity 40a may be connected to the bottom area of the second cavity 40b through the water gap 45. The bottom side edge of the dividing rib 44 may be lower than the boss surface, so that the drainage area 414 may be distributed in the bottom area of the first cavity 40a and the bottom area of the second cavity 40b.
[0086] When the drain pump 5 stops running, some residual water returns to the drain area 414. When the water level in the drain area 414 is higher than the bottom edge of the dividing rib 44, a liquid seal can be achieved between the first cavity 40a and the second cavity 40b, preventing the odor in the second cavity 40b from entering the first cavity 40a, thereby effectively preventing the odor from returning to the cooking cavity 20.
