The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the specification of this application includes any and all combinations of one or more of the relevant listed items.

[0039] After using a cooking device, such as a steam oven, the water vapor in the inner pot of the cooking device will condense and remain on the bottom wall, forming a residual water accumulation, and food residues may also fall during the switching process of the steaming and baking functions. In order to prevent the residual water or food residues from remaining for a long time and producing odor, users are usually required to wipe and clean them with paper towels or rags multiple times, which is time-consuming and labor-intensive. In the related prior art, some cooking devices are provided with a drainage device, which is opened and closed by a switch valve and filters food residues through a filter basket arranged above the switch valve. However, the cost of control through the switch valve is high, and the overall structure of the drainage device is complex, large in size, and difficult to disassemble and use.

[0040] In order to solve the above problems, Figures 1 to 8 As shown, the present invention provides a drainage device 100, which has a simple structure and is easy to operate.

[0041] like Figure 1 、 Figure 3 and Figure 7 As shown, specifically, the drainage device 100 is used to be arranged in a cooking device, the cooking device includes an inner pot 200, and the drainage device 100 includes a drainage member 1, a baffle 2 and a filter assembly 3, wherein: the drainage member 1 is used to be arranged on the bottom wall of the inner pot 200, and the drainage member 1 is provided with a drainage channel 11 whose one end is connected to the inner pot 200; the baffle 2 is arranged in the drainage channel 11 and is provided with a drainage hole 21; the filter assembly 3 is detachably arranged in the drainage channel 11 and is located above the baffle 2, the filter assembly 3 includes a filter member 31 and a blocking member 32 arranged on the filter member 31, the filter member 31 is provided with a filter hole 311, and the blocking member 32 can move relative to the filter member 31 to open or block the drainage hole 21.

[0042] After the cooking is completed, the water vapor in the inner pot 200 condenses and flows to the bottom wall of the inner pot 200, and the food residue on the bottom wall of the inner pot 200 flows into the drainage channel 11 together with the residual water, and the residual water can flow to the top of the baffle 2 through the filter hole 311. The food residue remains above the filter element 31 under the filtering effect of the filter hole 311, and the blocking member 32 is controlled to move relative to the filter element 31 to the open state, so that the blocking member 32 opens the drainage hole 21, and the residual water above the baffle 2 can be discharged from the inner pot 200 through the drainage hole 21. After the drainage is completed, the user can disassemble the filter element 31. The filter assembly 3 is used to remove the food residue on the filter element 31. In this way, it is possible to prevent residual water or food residue from remaining in the inner pot 200 for too long and producing odor or affecting the taste of food. The user does not need to wipe the bottom wall of the inner pot 200 with a paper towel or a rag many times, and the food residue will not clog the drainage channel 11, which is convenient for cleaning and saves manpower. In addition, the blocking member 32 is integrally arranged on the filter element 31, so that the overall structure of the drainage device 100 is simple and the cost is low, so that the user can disassemble and use the filter assembly 3. At the same time, the integrated filter assembly 3 can also reduce the overall volume of the drainage device 100, thereby reducing the space occupied by the drainage device 100 in the cooking equipment. Since no other structure is required under the baffle 2, it can avoid affecting the drainage efficiency of the drainage channel 11, and at the same time, the overall volume of the drainage device 100 can be further reduced.

[0043] like Figures 7 and 8 As shown, in one embodiment, the drainage device 100 further includes a water tank 4 for placement below the inner pot 200. The water tank 4 is connected to the end of the drainage channel 11 away from the inner pot 200. Excess water discharged from the drainage channel 11 can flow into the water tank 4 for collection. After drainage is complete, or when the water level in the water tank 4 reaches the maximum water level, the user can remove the water tank 4 and empty the water, making the operation simple. The drainage device may also include a drain pipe 5, the ends of which are connected to the end of the drainage channel 11 away from the inner pot 200 and the water tank 4, respectively. This allows a certain distance between the water tank 4 and the drainage member 1 to prevent interference between the water tank 4 and other components within the cooking device.

[0044] Of course, in other embodiments, the end of the drainage channel 11 away from the inner tank 200 can also be connected to an external drainage structure such as a sewer. As long as the remaining water in the inner tank 200 can be discharged through the drainage channel 11, the embodiment of the utility model does not make specific restrictions here.

[0045] like Figures 2 to 3 As shown, in one embodiment, the filter element 31 includes a bottom 313 and a side portion 314. The filter aperture 311 includes a plurality of first filter apertures 3111 disposed on the bottom 313, with the plurality of first filter apertures 3111 spaced apart. The filter aperture 311 also includes a plurality of second filter apertures 3112 disposed on the side portion 314, with the plurality of second filter apertures 3112 spaced apart along the circumference of the side portion 314. The filter aperture 311 also includes a plurality of second filter apertures 3112 disposed on the side portion 314, with the plurality of second filter apertures 3112 spaced apart along the circumference of the side portion 314. The simultaneous provision of the first filter apertures 3111 and the second filter apertures 3112 can improve drainage efficiency and shorten drainage time. The first filter apertures 3111 can be configured as smaller circular through-holes to prevent food residue above the bottom 313 from passing through the first filter apertures 3111 and onto the barrier 2. Each second filter aperture 3112 can be a strip-shaped hole extending along the height of the side portion 314 to further improve drainage efficiency.

[0046] Of course, in other embodiments, only the first filter hole 3111 may be provided on the bottom 313, or only the second filter hole 3112 may be provided on the side 314. As long as it is ensured that in the open state, the remaining water above the filter element 31 can flow to the drainage hole 21 through the filter hole 311, and the food residue always remains above the filter element 31, the embodiments of the present invention do not impose specific restrictions here.

[0047] like Figures 3 and 4 As shown, in one embodiment, the bottom 313 of the filter element 31 is provided with a relief hole 312 corresponding to the drain hole 21. The blocking member 32 passes through the relief hole 312 and can be raised and lowered relative to the filter element 31. In the blocked state, the outer peripheral wall of the blocking member 32 partially abuts the inner peripheral wall of the drain hole 21. The relief hole 312 is spaced apart from the first filter hole 3111 on the bottom 313. Passing through the relief hole 312 allows the blocking member 32 to be partially positioned above the bottom 313, preventing the blocking member 32 from occupying excessive space between the filter element 31 and the blocking member 2. When the blocking piece 32 is controlled to descend relative to the filter element 31, the portion of the blocking piece 32 located below the bottom 313 can be inserted into the drainage hole 21, so that the outer peripheral wall of the blocking piece 32 fits with the inner peripheral wall of the drainage hole 21 to block the drainage hole 21; when the blocking piece 32 is controlled to rise relative to the filter element 31, the blocking piece 32 can be detached from the drainage hole 21 to open the drainage hole 21. The movement mode of the blocking piece 32 is simple and easy for users to control.

[0048] Of course, in other embodiments, the blocking member 32 may be controlled to rotate or move relative to the filter member 31. In the blocking state, the blocking member 32 covers the drain hole 21 to block the drain hole 21; in the open state, the blocking member 32 is offset from the drain hole 21 to open the drain hole 21.

[0049] Furthermore, a waterproof layer is provided on the outer wall of the sealing member 32 and the inner wall of the drain hole 21. The waterproof layer may be a waterproof coating, a waterproof gasket, or the like. In the sealed state, the waterproof layer further improves the seal between the outer wall of the sealing member 32 and the inner wall of the drain hole 21, preventing water leakage from the drain hole 21 and also providing a deodorizing effect.

[0050] like Figures 3 and 4 As shown, the filter assembly 3 also includes a housing 33 disposed within the filter element 31. The housing 33 is sleeved over the sealing element 32. The housing 33 is connected to the filter element 31, supporting the sealing element 32 and limiting its range of motion, thereby improving its stability when raised or lowered relative to the filter element 31. Furthermore, the housing 33 protects the sealing element 32 and acts as a waterproof barrier, preventing residual water or food residue from contaminating the sealing element 32 and affecting its sealing effect on the drain hole 21.

[0051] like Figures 5 and 6 As shown, the filter assembly 3 also includes a limit member 34 arranged on the inner wall of the shell 33. Along the circumference of the limit member 34, the limit member 34 is provided with a plurality of slot groups 341, and each slot group 341 includes a first slot 3411 and a second slot 3412 with the slot opening facing the block 2; the blocking member 32 can rotate relative to the filter member 31, and the outer wall of the blocking member 32 is provided with a block 321 that can cooperate with the first slot 3411 and the second slot 3412. In the open state, the block 321 cooperates with any first slot 3411, and in the blocked state, the block 321 cooperates with any second slot 3412. Specifically, the number of blocks 321 can be equal to or less than the number of slot groups 341. When one block 321 engages with any first slot 3411, the other blocks 321 also engage with any other first slot 3411. Similarly, when one block 321 engages with any second slot 3412, the other blocks 321 also engage with any other second slot 3412. The depth of the first slot 3411 is greater than the depth of the second slot 3412, so that the height of the blocking member 32 is higher when the block 321 engages with the first slot 3411 than when it engages with the second slot 3412. The engagement of the block 321 with the first slot 3411 or the second slot 3412 ensures the stability and reliability of the blocking member 32 in both the blocked and open states.

[0052] When it is necessary to control the blocking member 32 to move from the blocking state to the open state, the blocking member 32 can be controlled to descend first so that the block 321 disengages from the second slot 3412, and then the blocking member 32 can be controlled to rotate relative to the filter element 31. When the block 321 is aligned with any first slot 3411, the blocking member 32 can be controlled to rise so that the block 321 cooperates with the first slot 3411 to stabilize the blocking member 32 in the open state; similarly, when it is necessary to control the blocking member 32 to move from the open state to the blocking state, the blocking member 32 can be controlled to descend first so that the block 321 disengages from the first slot 3411, and then the blocking member 32 can be controlled to rotate relative to the filter element 31. When the block 321 is aligned with any second slot 3412, the blocking member 32 can be controlled to rise so that the block 321 cooperates with the second slot 3412 to stabilize the blocking member 32 in the blocking state.

[0053] like Figures 5 and 6 As shown, the end of the block 321 facing away from the stopper 2 is provided with a first inclined surface 3211. The first inclined surface 3211 tilts upward in the direction of rotation of the blocking member 32. The bottom wall of the second engaging slot 3412 is provided with a second inclined surface 3413 that slidably engages with the first inclined surface 3211. The stopper 34 also includes a plurality of guide inclined surfaces 343 that slidably engage with the first inclined surface 3211. Each guide inclined surface 343 is used to connect two adjacent engaging slot groups 341. The first inclined surface 3211 cooperates with the second inclined surface 3413 and the guide inclined surfaces 343 to guide the blocking member 32 as it rotates relative to the filter element 31, thereby facilitating user control of the rotation of the blocking member 32.

[0054] like Figures 5 and 6 As shown, the filter assembly 3 further includes an elastic member 35 disposed between the blocking member 32 and the housing 33. At least in the blocking state, the elastic member 35 is compressed. The elastic member 35 enables the blocking member 32 to automatically rise to a position where the block 321 engages with the first engaging groove 3411 or the second engaging groove 3412 under the action of elastic force, thereby further facilitating user operation and improving the stability and reliability of the blocking member 32 in both the blocking and open states.

[0055] Taking the blocking member 32 as an example of rotating in direction A relative to the filter element 31, when the blocking member 32 is controlled to descend so that the block 321 is disengaged from the second slot 3412, the elastic member 35 is compressed and can exert an upward elastic force on the blocking member 32. After the user releases the block 32, the blocking member 32 can rise under the elastic force of the elastic member 35, and the first inclined surface 3211 cooperates with the guide inclined surface 343, so that the blocking member 32 rotates in direction A relative to the filter element 31 until the block 321 is disengaged from the first slot 3412. 411 cooperates; similarly, when the blocking member 32 is controlled to descend so that the block 321 is disengaged from the first slot 3411, the elastic member 35 is compressed and can apply an upward elastic force to the blocking member 32. After the user releases it, the blocking member 32 can rise under the elastic force of the elastic member 35, and through the first inclined surface 3211 and the second inclined surface 3413, the blocking member 32 is rotated relative to the filter element 31 along direction A to the position where the block 321 and the second slot 3412 cooperate.

[0056] like Figures 5 and 6 As shown, the filter assembly 3 also includes a pressing member 36, which is sleeved on the end of the blocking member 32 away from the blocking member 2. The pressing member 36 can be raised and lowered relative to the blocking member 32, and a portion of the pressing member 36 extends out of the housing 33. The limiting member 34 is also provided with a limiting groove 342 extending along the lifting direction of the pressing member 36, and the outer wall of the pressing member 36 is provided with a slider 361 that can slide within the limiting groove 342. The user can press the portion of the pressing member 36 that extends out of the housing 33 outside the housing 33, so that the pressing member 36 pushes the blocking member 32 downward to control the blocking member 32, which is simple and convenient to operate. The limiting groove 342 can limit the sliding range of the slider 361, thereby limiting the sliding range of the pressing member 36, preventing the pressing member 36 from rotating together with the blocking member 32, and also preventing the pressing member 36 from falling out of the housing 33.

[0057] like Figures 5 and 6As shown, there are multiple limiting slots 342 and sliders 361, which are arranged in a one-to-one correspondence with the first slots 3411. The limiting slots 342 are connected to the corresponding first slots 3411. The end of the slider 361 facing the block 321 is provided with a third inclined surface 3611 that can slide with the first inclined surface 3211. In the open state, the third inclined surface 3611 can abut against the block 321. When the block 321 engages with the first slot 3411, the first inclined surface 3211 of the block 321 abuts against the third inclined surface 3611 of the slider 361, thereby stabilizing the blocking member 32 in the open state. The third inclined surface 3611 can serve as a guide when the blocking member 32 moves from the open state to the blocked state, further facilitating the user's control of the rotation of the blocking member 32. Specifically, the user presses the pressing member 36 to push the blocking member 32 downward, causing the block 321 to disengage from the first slot 3411 and compressing the elastic member 35. After the user releases the pressing member 36, the blocking member 32 can rise under the elastic force of the elastic member 35. The first inclined surface 3211 cooperates with the third inclined surface 3611 and the second inclined surface 3413, causing the blocking member 32 to rotate relative to the filter element 31 in direction A to a position where the block 321 cooperates with the second slot 3412, thereby stabilizing the blocking member 32 in the blocking state. The slider 361 can be configured in a regular or irregular shape, such as a fan or trapezoid.

[0058] Furthermore, the housing 33 and the pressing member 36 can also serve as handles of the filter assembly 3 , so as to facilitate the user to disassemble and assemble the filter assembly 3 .

[0059] like Figure 7 As shown, an embodiment of the present invention further provides a cooking device comprising an inner pot 200 and the aforementioned drainage device 100. The drainage member 1 can be directly mounted on the bottom of the inner pot 200 or on a heating element mounted thereon. Furthermore, the drainage member 1 can be detachably connected to the inner pot 200 or the heating element via screws, snaps, or other means, allowing the user to remove and clean, replace, or repair the drainage member 1. In the assembled state, the drainage member 1 must be sealed against the inner pot 200 or the heating element to prevent residual water from flowing through the gap between the drainage member 1 and the inner pot 200 or the heating element and into the lower portion of the inner pot 200. It is understood that the top surface of the drainage member 1 must be equal to or lower than the bottom surface of the inner pot 200 or the top surface of the heating element to ensure that residual water in the inner pot 200 can flow properly into the drainage channel 11. Specifically, the cooking device can be a steam oven, microwave oven, or all-in-one steam-bake appliance, which may cause residual water to accumulate in the inner pot 200 during cooking. This embodiment of the present invention is not particularly limited here.
