[0051] The embodiments of the present disclosure provide a kitchen appliance, which can be an integrated stove, a stove-steamer-oven all-in-one machine, etc. The embodiments take the integrated stove as an example for illustration, as shown in Figure 1 The integrated stove of the embodiments includes a head 2000, a cooking device 1000, a stove 3000, a body 4000, and a flue 5000. The head 2000 and the stove 3000 are arranged on the body 4000, the head 2000 is in communication with the flue 5000, and the head 2000 is used to absorb the oil fume in the environment. The oil fume absorbed by the head 2000 can be discharged through the flue 5000, thereby realizing the absorption effect of the integrated stove on the oil fume in the environment. In addition, as shown in Figure 1 The stove 3000 can heat the pot, thereby realizing the cooking and processing of food. Specifically, the stove 3000 can be a gas stove, an electromagnetic oven, etc. As shown in Figure 1 The cooking device 1000 is embedded on the body 4000, and the cooking device 1000 can generate steam and use the steam to cook and process food. Specifically, the cooking device 1000 can be a steamer-oven, a steamer, etc. The steamer-oven has a steaming function and a baking function, and the user can select the functions of only steaming, only baking, or steaming and baking at the same time to realize the switching of different cooking modes. Of course, the embodiments of the present disclosure also separately protect the aforementioned cooking device 1000. The integrated stove integrates the head 2000, the cooking device 1000, and the stove 3000 into one, which can realize the multifunctional cooking effect to meet the different needs of the user for different cooking modes.

[0052] As shown in Figure 1 The head 2000 includes a smoke collecting cavity mechanism 2100 and a smoke baffle 2200. The smoke collecting cavity mechanism 2100 is provided with a smoke suction port 2101, and the oil fume in the environment can enter the smoke collecting cavity mechanism 2100 through the smoke suction port 2101. The smoke baffle 2200 is arranged at the smoke suction port 2101, and the arrangement of the smoke baffle 2200 can effectively improve the oil fume absorption effect of the integrated stove.

[0053] As shown in Figure 1As shown, the stove 3000 includes a burner 3100, a stove housing 3200, and a pot rack 3300. The stove housing 3200 is mounted on the body 4000, and the burner 3100 and pot rack 3300 are mounted on the stove housing 3200. The burner 3100 is used to heat the pot, and the pot rack 3300 surrounds the burner 3100 and is used to support the pot.

[0054] like Figure 1 As shown, the cooking device 1000 includes a housing and a cooking cavity 200. The cooking cavity 200 is disposed within the housing. The cooking cavity 200 generates steam and uses the steam to cook and process food. The housing provides good protection for the cooking cavity 200. Furthermore, as... Figure 1 As shown, the cooking apparatus 1000 also includes a steam system 400, which is connected to the interior of the cooking cavity 200. The steam system 400 is used to introduce sufficient steam into the interior of the cooking cavity 200, and the steam can heat the food inside the cooking cavity 200. Furthermore, as... Figure 1 As shown, the cooking appliance 1000 also includes a water collection tank 300, which is disposed at the opening of the cooking cavity 200. The water collection tank 300 is used to collect water that slides off the door assembly of the cooking appliance 1000 or water that overflows from the cooking cavity 200.

[0055] In addition, such as Figure 1 As shown, the cooking cavity 200 also includes a drainage mechanism 100. At least one of the cooking cavity 200, the water collection tank 300, and the steam system 400 can be connected to the drainage mechanism 100, thereby enabling the effective recovery of the corresponding accumulated water in the cooking cavity 200, the water collection tank 300, and the steam system 400. This avoids residual water remaining in the cooking cavity 200, the water collection tank 300, and the steam system 400 after cooking, and can reduce the cleaning burden and difficulty for users regarding residual water inside the cooking equipment 1000 to a certain extent.

[0056] The existing cooking device 1000 also includes an oil cup 500, and a draining mechanism 100 is connected to the oil cup 500. The residual water collected by the draining mechanism 100 will be discharged into the oil cup 500. Although the user does not need to clean or empty the inside of the draining mechanism 100, the user still needs to clean the oil cup 500 from time to time and more frequently, which will increase the user's cleaning burden and cleaning difficulty of the oil cup 500 to a certain extent.

[0057] To solve the above problems, such as Figure 2As shown, the liquid drainage mechanism 100 comprises a box body 10, a liquid inlet pipe 20, an exhaust pipe 30, and an atomization mechanism 40. The liquid inlet pipe 20 is in communication with the interior of the box body 10. The exhaust pipe 30 is in communication with the interior of the box body 10 and the flue 5000, respectively. At least part of the atomization mechanism 40 is arranged in the interior of the box body 10. The liquid in the box body 10 is atomized by the atomization mechanism 40 to form gas, which is discharged to the flue 5000 through the exhaust pipe 30. Through the arrangement of the above-mentioned liquid drainage mechanism 100, the wastewater in the liquid drainage mechanism 100 can be directly converted into a gaseous state and discharged from the flue 5000, thereby reducing the cleaning frequency and difficulty of the user for the liquid drainage mechanism 100 and the oil cup 500.

[0058] It should be noted that the type of the atomization mechanism 40 can be an ultrasonic atomizer, a jet atomizer, a vibrating mesh atomizer, etc. All mechanisms capable of atomizing the liquid in the interior of the box body 10 are within the protection scope of the embodiments of the present disclosure.

[0059] In an optional embodiment, as shown in Figure 2 The box body 10 comprises a box body body 11 and an upper end cover 12. The box body body 11 comprises a bottom plate 111 and a side wall 113 surrounding the outer periphery of the bottom plate 111 and forming an upper opening. The upper end cover 12 is arranged at the upper opening. By removing the upper end cover 12, the user can clean the interior of the box body 10.

[0060] In an optional embodiment, as shown in Figure 2 The box body 10 further comprises a sealing member 13 arranged between the upper end cover 12 and the side wall 113. The sealing member 13 can achieve a better sealing effect for the box body 10, prevent the liquid in the interior of the box body 10 from overflowing, prevent the short circuit of the electrical components around the box body 10, and ensure the better use effect and longer service life of the electrical components around the box body 10.

[0061] As shown in Figure 2 The sealing member 13 can be a ring-shaped sealing ring arranged in the circumferential direction of the upper end of the side wall 113. The ring-shaped sealing ring can achieve a better sealing effect for the gap between the side wall 113 and the upper end cover 12. Specifically, the sealing member 13 can be made of flexible and elastically deformable materials such as rubber and silicone.

[0062] As shown in Figure 2 At least one of the upper end of the side wall 113 and the upper end cover 12 is provided with a ring-shaped groove. The ring-shaped sealing ring is arranged in the ring-shaped groove. The arrangement of the ring-shaped groove can achieve a better positioning and limiting effect for the ring-shaped sealing ring, and improve the assembly efficiency of the ring-shaped sealing ring and the side wall 113 or the upper end cover 12.

[0063] Since there may be some impurities in the liquid in the box body 10, if the atomization mechanism 40 is arranged at a lower position, the atomization mechanism 40 will be in contact with the impurities, which will affect the actual contact area of the atomization mechanism 40 with the liquid on the one hand, and will also cause corrosion to the atomization end of the atomization mechanism 40, thereby affecting the atomization effect and service life of the atomization mechanism 40. In order to solve the above problems, in an optional embodiment, as shown in Figure 2 the atomization mechanism 40 is arranged above the bottom plate 111, and under the action of sedimentation, the impurities in the liquid in the box body 10 will deposit to the bottom plate 111, and the relatively clear liquid will be at a relatively upper position. The atomization mechanism 40 atomizes the relatively clear liquid at the relatively upper position, which can ensure good atomization effect of the atomization mechanism 40 on the relatively clear liquid, and can also avoid corrosion of the liquid to the atomization mechanism 40, thereby ensuring a longer service life of the atomization mechanism 40.

[0064] In an optional embodiment, as shown in Figure 2 the exhaust pipe 30 includes an exhaust pipe body 31 and a limiting portion 32. The exhaust pipe body 31 has an air inlet end 311 and an air outlet end 312. The air inlet end 311 is located inside the box body 10. The limiting portion 32 is formed by extending from the air inlet end 311 towards the center line of the exhaust pipe body 31. The atomization mechanism 40 is arranged inside the exhaust pipe body 31 and located on the limiting portion 32. Through the above structure, better installation and positioning effect of the atomization mechanism 40 can be achieved.

[0065] In an optional embodiment, as shown in Figure 2 the bottom plate 111 is arranged protruding downward. A drain hole 1111 is formed at the lowest position of the bottom plate 111, so that the impurities deposited inside the box body 10 can flow out of the box body 10 through the drain hole 1111 more smoothly.

[0066] In an optional embodiment, as shown in Figure 2 the liquid inlet pipe 20 has a liquid inlet 21 and a liquid outlet 22. The liquid outlet 22 is arranged above the drain hole 1111 and opposite to the drain hole 1111, which can avoid the liquid entering the liquid inlet pipe 20 from exciting the impurities on the bottom plate 111, and to a certain extent, reduce the contact between the atomization mechanism 40 and the impurities.

[0067] In an optional embodiment, as shown in Figure 2 the liquid discharge mechanism 100 further includes an on-off mechanism 80. The drain hole 1111 is connected to the oil cup 500 through the on-off mechanism 80. When the on-off mechanism 80 is opened, the impurities on the bottom plate 111 can flow to the oil cup 500 through the on-off mechanism 80, thereby ensuring the cleanliness inside the liquid discharge mechanism 100.

[0068] In an optional embodiment, as shown in Figure 2As shown, the box body 11 further comprises a drain pipe 112 formed by extending downward from the drain hole 1111, and the on-off mechanism 80 further comprises a communication pipe 81, the drain pipe 112 is in communication with the communication pipe 81, so as to realize better communication effect between the inside of the box body 11 and the on-off mechanism 80, and ensure that the impurities flowing out of the drain hole 1111 can smoothly pass through the on-off mechanism 80 and enter the oil cup 500.

[0069] In an optional embodiment, as shown in Figure 2 As shown, the liquid discharge mechanism 100 further comprises a temperature detection mechanism 50 and a controller, at least part of the temperature detection mechanism 50 is arranged inside the box body 10, the temperature detection mechanism 50 is used for detecting the temperature of the liquid in the box body 10, and the atomization mechanism 40 and the temperature detection mechanism 50 are electrically connected with the controller, when the temperature detection mechanism 50 detects that the temperature of the liquid in the box body 10 is high, the controller controls the atomization mechanism 40 not to work, so as to avoid damage caused by atomizing the high-temperature liquid by the atomization mechanism 40, thereby being able to ensure a longer service life of the atomization mechanism 40. For example, the temperature detection mechanism 50 can be an infrared temperature measurement mechanism, a thermocouple temperature measurement mechanism, a thermistor temperature measurement mechanism, etc., all temperature detection mechanisms 50 capable of detecting the temperature of the liquid in the box body 10 are within the protection scope of this optional embodiment.

Through the cooperation of the Hall sensor 622 and the magnetic member 611, the liquid level of the liquid in the box body 10 can be accurately detected. Since the principle of detecting the liquid level by the cooperation of the Hall sensor 622 and the magnetic member 611 is a relatively mature field and technology in the art, this optional embodiment will not be further introduced.

[0072] In an optional embodiment, as shown in Figure 2 The Hall sensors 622 are arranged in at least two, and the at least two Hall sensors 622 are arranged at intervals along the height direction of the box body 10, so that the different liquid levels in the box body 10 can be accurately detected.

[0073] In an optional embodiment, as shown in Figure 2 The circuit board 62 is arranged outside the box body 10, so that the circuit board 62 is prevented from being in contact with the liquid in the box body 10, the short circuit of the circuit board 62 is avoided, the normal operation of the circuit board 62 is ensured, and the liquid level detection mechanism 60 can always have a good detection effect on the liquid level in the box body 10.
