[0065] Embodiment 1

[0066] The present disclosure provides a kitchen appliance, which may be an integrated stove, a stove-steaming and baking all-in-one machine, etc. The present disclosure takes the integrated stove as an example for explanation. Figure 1As shown, the integrated stove of this embodiment includes a head 2000, a cooking device 1000, a stove 3000, a body 4000 and a flue 5000, wherein the head 2000 and the stove 3000 are arranged on the body 4000, the head 2000 is connected with the flue 5000, the head 2000 is used to absorb the oil smoke in the environment, and the oil smoke absorbed by the head 2000 can be discharged through the flue 5000, thereby realizing the integrated stove's absorption effect on the oil smoke in the environment. In addition, as Figure 1 As shown, the stove 3000 can heat the pot, thereby cooking and processing the food. Specifically, the stove 3000 can be a gas stove, an induction cooker, etc. Figure 1 As shown, the cooking device 1000 is embedded in the body 4000. The cooking device 1000 can generate steam and use steam to cook and process food. Specifically, the cooking device 1000 can be a steam oven, a steam box, etc., wherein the steam oven has a steaming function and a baking function. The user can switch between different cooking methods by selecting only steaming, only baking, or both steaming and baking. Of course, the embodiment of the present disclosure also separately protects a cooking device 1000 mentioned above. The integrated stove can achieve a multifunctional cooking effect by integrating the head 2000, the cooking device 1000, and the stove 3000 into one, so as to meet the different needs of users for different cooking methods.

[0067] like Figure 1 As shown, the machine head 2000 includes a smoke collecting chamber mechanism 2100 and a smoke baffle 2200. The smoke collecting chamber mechanism 2100 is provided with a smoke outlet 2101. Oil smoke in the environment can enter the smoke collecting chamber mechanism 2100 through the smoke outlet 2101. The smoke baffle 2200 is arranged at the smoke outlet 2101. The setting of the smoke baffle 2200 can effectively improve the oil smoke absorption effect of the integrated stove.

[0068] like Figure 1 As shown, the stove 3000 includes a burner 3100, a stove shell 3200 and a pot rack 3300, wherein the stove shell 3200 is arranged on the body 4000, the burner 3100 and the pot rack 3300 are arranged on the stove shell 3200, the burner 3100 is used to heat the pot, and the pot rack 3300 is arranged around the periphery of the burner 3100 and is used to support the pot.

[0069] like Figure 1 As shown, the cooking device 1000 includes a housing and a cooking cavity 200. The cooking cavity 200 is disposed in the housing. The cooking cavity 200 generates steam and uses the steam to cook and process food. The housing can provide a good protection effect for the cooking cavity 200. Figure 1As shown, the cooking device 1000 further includes a steam system 400, which is connected to the interior of the cooking cavity 200. The steam system 400 is used to pass sufficient steam into the interior of the cooking cavity 200, and the steam can heat the food in the cooking cavity 200. Figure 1 As shown, the cooking device 1000 further includes a water collecting tank 300 , which is disposed at an open portion of the cooking cavity 200 . The water collecting tank 300 is used to receive water that slides down the door assembly of the cooking device 1000 or water that overflows from the cooking cavity 200 .

[0070] After the cooking device 1000 finishes working, there is residual water in the cooking cavity 200, the water collecting tank 300 and the steam system 400. The cooking cavity 200, the water collecting tank 300 and the steam system 400 all need to be cleaned by the user in time, which greatly increases the cleaning burden of the user on the cooking device 1000.

[0071] In order to solve the above problems, Figure 2 and Figure 3 As shown, the cooking device 1000 also includes a first on-off component 90 and a drain mechanism 100. The cooking cavity 200, the water collecting tank 300 and the steam system 400 are all connected to the drain mechanism 100 through the first on-off component 90. The first on-off component 90 can adjust the connectivity between the cooking cavity 200, the water collecting tank 300 and the steam system 400 and the drain mechanism 100 respectively. When the cooking device 1000 is finished working, the first on-off component 90 can make the cooking cavity 200, the water collecting tank 300 and the steam system 400 connected to the drain mechanism 100 respectively, and can realize the automatic recovery of residual water inside the cooking cavity 200, the water collecting tank 300 and the steam system 400 to the drain mechanism 100. There is no need for the user to clean the residual water in the cooking cavity 200, the water collecting tank 300 and the steam system 400 respectively, thereby effectively reducing the cleaning burden of the user on the cooking device 1000.

[0072] In an optional embodiment, if Figure 2As shown, the first on-off assembly 90 includes a first on-off mechanism 91, and the cooking cavity 200, the water collecting tank 300 and the steam system 400 are all connected to the drain mechanism 100 through the first on-off mechanism 91. When the first on-off mechanism 91 is in an open state, the residual water in the cooking cavity 200, the water collecting tank 300 and the steam system 400 can be quickly discharged to the drain mechanism 100. Since the first on-off assembly 90 in this optional embodiment only includes one first on-off mechanism 91, only one first on-off mechanism 91 can realize the synchronous control of the residual water discharge in the cooking cavity 200, the water collecting tank 300 and the steam system 400. The structure of the first on-off assembly 90 is simple, involves few parts, has low cost and is easy to control. Exemplarily, the first on-off mechanism 91 can be an on-off valve, and all structures that can realize pipeline on-off are within the protection scope of this optional embodiment.

[0073] In an optional embodiment, if Figure 3 As shown, the first on-off assembly 90 includes a second on-off mechanism 92, a third on-off mechanism 93 and a fourth on-off mechanism 94, the cooking cavity 200 is connected to the drain mechanism 100 through the second on-off mechanism 92, the water collecting tank 300 is connected to the drain mechanism 100 through the third on-off mechanism 93, and the steam system 400 is connected to the drain mechanism 100 through the fourth on-off mechanism 94, that is, the residual water in the cooking cavity 200, the water collecting tank 300 and the steam system 400 can be discharged independently controlled, and the first on-off assembly 90 can realize the separate control of the residual water in different states in the cooking cavity 200, the water collecting tank 300 and the steam system 400, which can meet the different usage scenarios of the cooking device 1000 and realize the diversified control of the residual water discharge. Exemplarily, the second on-off mechanism 92, the third on-off mechanism 93 and the fourth on-off mechanism 94 can be on-off valves, and all structures that can realize the on-off of the pipeline are within the protection scope of this optional embodiment.

[0074] In an optional embodiment, if Figure 4 As shown, the steam system 400 includes a water tank 410, a pipeline 420, and a fifth on-off mechanism 430, wherein the water tank 410 is connected to the fourth on-off mechanism 94 through the pipeline 420, and the fifth on-off mechanism 430 is arranged on the pipeline 420. Through the arrangement of the fifth on-off mechanism 430, it is possible to realize the switching between only the liquid in the pipeline 420 being discharged to the drain mechanism 100 and the liquid in the water tank 410 being discharged to the drain mechanism 100. Specifically, when the fifth on-off mechanism 430 is in a closed state and the fourth on-off mechanism 94 is in an open state, only the liquid in the pipeline 420 can be discharged to the drain mechanism 100; when the fifth on-off mechanism 430 is in an open state and the fourth on-off mechanism 94 is in an open state, the liquid in the water tank 410 can be discharged to the drain mechanism 100 through the pipeline 420.

[0075] like Figure 1 As shown, the cooking device 1000 also includes an oil cup 500. The drain mechanism 100 is connected to the oil cup 500. The residual water collected by the drain mechanism 100 will be discharged into the oil cup 500. Although the user does not need to clean or pour water from the inside of the drain mechanism 100, the user still needs to clean the oil cup 500 irregularly and more frequently, which to a certain extent will increase the user's cleaning burden and difficulty of the oil cup 500.

[0076] In order to solve the above problems, Figure 5 As shown, the discharge mechanism 100 includes a box body 10, a liquid inlet pipe 20, an exhaust pipe 30 and an atomizing mechanism 40. The liquid inlet pipe 20 is connected to the interior of the box body 10, and the exhaust pipe 30 is respectively connected to the interior of the box body 10 and the flue 5000. At least part of the atomizing mechanism 40 is arranged inside the box body 10. The gas formed by the liquid in the box body 10 through the atomizing mechanism 40 can be discharged to the flue 5000 through the exhaust pipe 30. Through the setting of the above-mentioned discharge mechanism 100, the waste water in the discharge mechanism 100 can be directly converted into gas and discharged from the flue 5000, thereby reducing the frequency and difficulty of cleaning the discharge mechanism 100 and the oil cup 500 by the user.

[0077] It should be noted that the type of the atomization mechanism 40 may be an ultrasonic atomizer, a jet atomizer, a vibrating mesh atomizer, etc. All mechanisms capable of atomizing the liquid inside the box body 10 are within the protection scope of the embodiments of the present disclosure.

[0078] In an optional embodiment, if Figure 5 As shown, the box body 10 includes a box body 11 and an upper end cover 12, wherein the box body 11 includes a bottom plate 111 and side walls 113, the side walls 113 are arranged around the periphery of the bottom plate 111 and form an upper opening, and the upper end cover 12 is opened at the upper opening. By removing the upper end cover 12, it is convenient for the user to clean the inside of the box body 10.

[0079] In an optional embodiment, if Figure 5 As shown, the box body 10 also includes a seal 13, which is arranged between the upper end cover 12 and the side wall 113. The setting of the seal 13 can achieve a better sealing effect for the box body 10, avoid the overflow of liquid inside the box body 10, avoid short circuit of electrical components around the box body 10, and ensure that the electrical components around the box body 10 always have a good use effect and a long service life.

[0080] For example, Figure 5As shown, the seal 13 may be an annular seal ring, which is arranged in the circumference of the upper end of the side wall 113, and the annular seal ring can achieve a good sealing effect on the gap between the side wall 113 and the upper end cover 12. Specifically, the seal 13 may be made of a flexible and elastically deformable material such as rubber or silicone.

[0081] like Figure 5 As shown, an annular groove is provided on at least one of the upper end of the side wall 113 and the upper end cover 12, and the annular sealing ring is arranged in the annular groove. The setting of the annular groove can achieve better positioning and limiting effects on the annular sealing ring, thereby improving the assembly efficiency of the annular sealing ring and the side wall 113 or the upper end cover 12.

[0082] Since there may be some impurities in the liquid in the box body 10, if the atomizing mechanism 40 is set at a lower position, the atomizing mechanism 40 will contact these impurities. On the one hand, the impurities will affect the actual contact area between the atomizing mechanism 40 and the liquid, and on the other hand, they will also cause corrosion to the atomizing end of the atomizing mechanism 40, thereby affecting the atomization effect and service life of the atomizing mechanism 40. In order to solve the above problems, in an optional embodiment, as Figure 5 As shown, the atomizing mechanism 40 is arranged above the bottom plate 111 at intervals. Under the action of the sedimentation agent, impurities in the liquid in the box body 10 will be deposited on the bottom plate 111, and the relatively clear liquid will be in a relatively upper position. The atomizing mechanism 40 atomizes the relatively clear liquid in a relatively upper position, which can ensure that the atomizing mechanism 40 has a better atomization effect on the relatively clear liquid, and can also avoid corrosion of the atomizing mechanism 40 by the liquid, thereby ensuring a longer service life of the atomizing mechanism 40.

[0083] In an optional embodiment, if Figure 5 As shown, 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 the air inlet end 311 toward the center line of the exhaust pipe body 31, the atomization mechanism 40 is arranged inside the exhaust pipe body 31 and is located on the limiting portion 32. Through the arrangement of the above structure, a better installation and positioning effect of the atomization mechanism 40 can be achieved.

[0084] In an optional embodiment, if Figure 5 As shown, the bottom plate 111 is protruding downward, and a drain hole 1111 is opened at the lowest position of the bottom plate 111 to facilitate the impurities deposited inside the box body 10 to be discharged to the outside of the box body 10 smoothly through the drain hole 1111.

[0085] In an optional embodiment, if Figure 5As shown, 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. It can prevent the liquid entering the liquid inlet pipe 20 from agitating the impurities on the bottom plate 111, thereby reducing the contact between the atomization mechanism 40 and the impurities to a certain extent.

[0086] In an optional embodiment, if Figure 5 As shown, the drainage mechanism 100 also includes a second on-off assembly 600, and the drain hole 1111 is connected to the oil cup 500 through the second on-off assembly 600. When the second on-off assembly 600 is opened, impurities on the bottom plate 111 can flow to the oil cup 500 through the second on-off assembly 600, thereby ensuring the cleanliness of the interior of the drainage mechanism 100.

[0087] In an optional embodiment, if Figure 5 As shown, the box body 11 also includes a drain pipe 112, which is formed by extending downward from the drain hole 1111. The second on-off assembly 600 also includes a connecting pipe 610. The drain pipe 112 is connected to the connecting pipe 610, thereby achieving a better connection effect between the interior of the box body 11 and the second on-off assembly 600, ensuring that impurities flowing out of the drain hole 1111 can smoothly pass through the second on-off assembly 600 and enter the oil cup 500.

[0088] In an optional embodiment, if Figure 5 As shown, the liquid discharge mechanism 100 also includes 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 to detect the temperature Q of the liquid in the box body 10. The atomization mechanism 40 and the temperature detection mechanism 50 are both electrically connected to the controller. When the temperature detection mechanism 50 detects that the temperature Q 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 the atomization mechanism 40 atomizing the high-temperature liquid, thereby ensuring a longer service life of the atomization mechanism 40. Exemplarily, 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 that can be realized for the liquid in the box body 10 are within the protection scope of this optional embodiment.

[0089] In an optional embodiment, if Figure 5 As shown, the liquid discharge mechanism 100 further includes a liquid level detection mechanism 60, at least part of which is disposed inside the box body 10, and the liquid level detection mechanism 60 is used to detect the liquid level H of the liquid in the box body 10, and the atomization mechanism 40 and the liquid level detection mechanism 60 are both electrically connected to the controller. Only when the liquid in the box body 10 is at a preset height H 预设After that, the atomizing mechanism 40 starts the atomizing work, which can avoid the atomizing mechanism 40 being in the powered atomizing state for a long time, and can effectively reduce the energy consumption of the atomizing mechanism 40.

[0090] In an optional embodiment, if Figure 5 As shown, specifically, the liquid level detection mechanism 60 includes a float 61 and a circuit board 62, the float 61 includes a magnetic member 611 and a float body 612, the float 61 is arranged inside the box body 10, and the float 61 can float on the liquid surface of the liquid inside the box body 10, the circuit board 62 includes a circuit board body 621 and a Hall sensor 622 arranged thereon, the circuit board 62 is electrically connected to the controller, and the Hall sensor 622 is used to sense the position of the magnetic member 611 to detect the liquid level H of the liquid in the box body 10. Through the cooperation of the Hall sensor 622 and the magnetic member 611, the liquid level H of the liquid in the box body 10 can be accurately detected. Since the principle of the Hall sensor 622 and the magnetic member 611 cooperating to detect the liquid level H is a relatively mature field and technology in the art, this optional embodiment will not be described in detail.

[0091] In an optional embodiment, if Figure 5 As shown, at least two Hall sensors 622 are provided, and at least two Hall sensors 622 are arranged at intervals along the height direction of the box body 10 , so as to realize accurate detection of different liquid levels H heights of the liquid in the box body 10 .

[0092] In an optional embodiment, if Figure 5 As shown, the circuit board 62 is arranged on the outside of the box body 10, which can prevent the circuit board 62 from contacting the liquid in the box body 10, prevent the circuit board 62 from short-circuiting, ensure the normal operation of the circuit board 62, and ensure that the liquid level detection mechanism 60 always has a good detection effect on the liquid level H of the liquid in the box body 10.

[0093] In an optional embodiment, if Figure 5 As shown, the discharge mechanism 100 also includes a limit box 70, which is fixedly connected to the box body 10. The limit box 70 is provided with a connected liquid inlet channel 71 and a guide groove 72. The float 61 is arranged in the guide groove 72. The guide groove 72 can guide the float 61 so that the float 61 can only move in the up and down directions, thereby avoiding the problem of inaccurate detection of the liquid level H of the liquid in the box body 10 by the liquid level detection mechanism 60 due to the float 61 flipping over during the up and down floating process.

[0094] Embodiment 2

[0095] The present disclosure provides a control method, which is applied to the cooking device 1000 disclosed in the first embodiment. Figure 6 As shown, the control method includes:

[0096] Obtaining the working status of the cooking device 1000; and

[0097] According to the working state of the cooking device 1000 , the working state of the first on-off component 90 is adjusted to adjust the connection states between the cooking cavity 200 , the water collecting tank 300 , and the steam system 400 and the drain mechanism 100 , respectively.

[0098] When the cooking device 1000 finishes working, the first on-off component 90 can connect the cooking cavity 200, the water collecting tank 300 and the steam system 400 with the drain mechanism 100 respectively, and can realize the automatic recovery of the residual water inside the cooking cavity 200, the water collecting tank 300 and the steam system 400 to the drain mechanism 100. The user does not need to clean the residual water in the cooking cavity 200, the water collecting tank 300 and the steam system 400 respectively, thereby effectively reducing the cleaning burden of the user on the cooking device 1000.

[0099] Embodiment 3

[0100] The present disclosure provides a control method, which is a further refinement of the control method disclosed in the second embodiment. Figure 7 As shown, the control method includes:

[0101] start;

[0102] like Figure 7 As shown, it is determined whether the flue 5000 is in working state: if so, the liquid level H and temperature Q of the liquid in the box body 10 are obtained, and the working state of the atomization mechanism 40 is controlled according to the liquid level H and / or temperature Q.

[0103] Through the above steps, the waste water in the drainage mechanism 100 can be directly transformed into gas and discharged from the flue 5000 , thereby reducing the frequency and difficulty of cleaning the drainage mechanism 100 and the oil cup 500 by the user.

[0104] For example, if H>preset height H 预设 When the atomizing mechanism 40 is controlled to work, if H≤preset height H 预设 When the atomizing mechanism 40 stops working, the atomizing mechanism 40 is controlled to atomize only the liquid with a higher liquid level H. The atomizing mechanism 40 does not need to be started for a long time, and is only started when the liquid level H is high enough, which can effectively reduce the energy consumption and work self-consumption of the atomizing mechanism 40 and the cooking device 1000, and effectively increase the service life of the atomizing mechanism 40 and the cooking device 1000.

[0105] For example, if Q<preset temperature Q 预设 , control the atomization mechanism 40 to work; if Q ≥ pre-Q 预设The atomizing mechanism 40 is controlled to stop working, so as to avoid damage of the atomizing mechanism 40 caused by working in a high temperature environment, and ensure a longer service life of the atomizing mechanism 40.

[0106] In an optional embodiment, H>H 预设 and Q<Q 预设 When these two conditions are met, the atomizing mechanism 40 is controlled to work, which can effectively reduce the energy consumption of the atomizing mechanism 40 and the cooking device 1000, and effectively increase the service life of the atomizing mechanism 40.

[0107] In an optional embodiment, it is also possible to first determine whether Q<Q 预设 Make a judgment, if Q<Q 预设 , the atomizing mechanism 40 can be controlled to work first, so as to achieve timely response of the atomizing mechanism 40 while ensuring a long service life of the atomizing mechanism 40, thereby avoiding the problem of excessive liquid in the box body 10 caused by the slow response of the atomizing mechanism 40.

[0108] Then, if Figure 7 As shown, the working state of the second on-off component 600 is controlled according to the liquid level H. Specifically, when H≤H 预设 When the second on-off assembly 600 is controlled to open, the impurities in the liquid will be deposited on the H 预设 In the following position, through the above steps, the impurities in the box body 10 can be discharged into the oil cup 500 through the second on-off component 600, and excessive liquid can be prevented from being discharged into the oil cup 500 from the second on-off component 600. The user only needs to clean the impurities in the oil cup 500, which can effectively reduce the frequency of cleaning the oil cup 500.

[0109] It should be noted that the second on-off component 600 can be controlled to open for a first preset time to ensure that all impurities in the box body 10 are completely discharged into the oil cup 500, wherein the first preset time can be obtained by experimental testing before the kitchen appliance leaves the factory. Of course, the user can also modify and set the first preset time according to his own usage scenarios, habits, regions, etc.

[0110] Next, determine whether the cooking device 1000 has stopped working: if not, return to the step of determining whether the flue 5000 is in working state; if yes, obtain the duration T of the cooking device 1000 stopping working, and independently control the discharge of residual water in the cooking cavity 200, the water collection tank 300 and the steam system 400 according to T, which can meet the different usage scenarios of the cooking device 1000 and realize a diversified, adaptable and highly free control method for the discharge of residual water at different positions, which can better match the user's usage habits of the cooking device 1000 and improve the user's usage experience and sense of adaptability.

[0111] For example, Figure 7 As shown, if the cooking device 1000 stops working for a period of time T greater than or equal to the first preset time T 预设1 , control the first on-off component 90 to connect the water collection tank 300 with the drain mechanism 100. When the cooking device 1000 is finished working, the user opens the door body, and the condensed water attached to the door body slides into the water collection tank 300. When there is too much condensed water at the bottom of the cooking cavity 200, the condensed water overflows from the cooking cavity 200 and flows into the water collection tank 300. The first on-off component 90 can make the condensed water flow into the water collection tank 300 and then into the drain mechanism 100. Specifically, it can be controlled as follows Figure 3 The third on-off mechanism 93 is shown in an open state. 预设1 It is relatively short, which can be 3s to 8s. It should be noted that the third on-off mechanism 93 can be controlled to open the second preset time length to meet the complete discharge of condensed water in the sump 300, and the second preset time length can be obtained through experiments before the cooking device 1000 leaves the factory. Of course, the user can also modify and set the second preset time length according to his own usage scenarios, habits, regions, etc.

[0112] For example, Figure 7 As shown, if the cooking device 1000 stops working for a period of time T greater than or equal to the second preset time T 预设2 , control the first on-off component 90 to connect the cooking cavity 200 with the drain mechanism 100. After the cooking device 1000 finishes working, the second preset time T is delayed 预设2 After the condensed water at the bottom of the cooking cavity 200 is sufficiently cooled, the first on-off component 90 is controlled to connect the cooking cavity 200 with the drain mechanism 100, so that the condensed water at the bottom of the cooking cavity 200 can be smoothly drained into the drain mechanism 100. Specifically, the following control can be performed: Figure 3 The second on-off mechanism 92 is shown in an open state. 预设2 It is relatively long and can be 50min to 2h. It should be noted that the second on-off mechanism 92 can be controlled to open for a third preset time to ensure complete discharge of condensed water in the cooking cavity 200. The third preset time can be obtained through experiments before the cooking device 1000 leaves the factory. Of course, the user can also modify and set the third preset time according to his own usage scenarios, habits, regions, etc.

[0113] For example, Figure 7 As shown, if the cooking device 1000 stops working for a period of time T greater than or equal to the third preset time T 预设3, control the first on-off component 90 to connect the pipe 420 of the steam system 400 with the drain mechanism 100. After the cooking device 1000 finishes working, the third preset time T is delayed 预设3 After the residual water in the pipe 420 of the steam system 400 is sufficiently cooled, the first on-off component 90 is controlled to connect the pipe 420 of the steam system 400 with the drain mechanism 100, so that the residual water in the pipe 420 of the steam system 400 can be smoothly drained into the drain mechanism 100. Specifically, the control can be as follows Figure 3 and Figure 4 The fourth on-off mechanism 94 shown is in the open state, and the control is as follows Figure 4 The fifth on-off mechanism 430 is shown in a closed state. 预设3 It is relatively long and can be 50min to 2h. It should be noted that the fourth on-off mechanism 94 can be controlled to open for a fourth preset time to meet the complete discharge of residual water in the pipe 420 of the steam system 400. The fourth preset time can be obtained through experiments before the cooking device 1000 leaves the factory. Of course, the user can also modify and set the fourth preset time according to his own usage scenarios, habits, regions, etc.

[0114] For example, Figure 7 As shown, if the cooking device 1000 stops working for a period of time T greater than or equal to the fourth preset time T 预设4 , control the first on-off component 90 to connect the water tank 410 of the steam system 400 to the drain mechanism 100. If the cooking device 1000 is not used for a long time, the water in the water tank 410 of the steam system 400 will produce bacteria, which is not conducive to the personal safety of the user. The water in the water tank 410 needs to be drained after a long time. Specifically, the cooking device 1000 is delayed for a fourth preset time T after the work is finished. 预设4 After the residual water in the water tank 410 of the steam system 400 is fully cooled, the first on-off component 90 is controlled to connect the water tank 410 of the steam system 400 with the drain mechanism 100, so that the residual water in the water tank 410 of the steam system 400 can be smoothly drained into the drain mechanism 100, thereby draining the deteriorated or bacteria-producing water to ensure the personal safety of the user. Specifically, the following can be controlled: Figure 3 and Figure 4 The fourth on-off mechanism 94 shown is in the open state, and the control is as follows Figure 4 The fifth on-off mechanism 430 is shown in an open state. 预设4It is relatively long and can be greater than or equal to one day. It should be noted that the fourth on-off mechanism 94 can be controlled to open the fifth preset time length to meet the complete discharge of residual water in the water tank 410 of the steam system 400, and the fifth preset time length can be obtained through experiments before the cooking device 1000 leaves the factory. Of course, the user can also modify and set the fifth preset time length according to his own usage scenarios, habits, regions, etc.

[0115] Embodiment 4

[0116] The present disclosure provides a control method, which is a further refinement of the control method disclosed in the third embodiment. Figure 8 As shown, the main difference between this control method and the control method of the second embodiment is that the steps of controlling the working state of the atomizing mechanism 40 according to the liquid level H and / or the temperature Q are specifically:

[0117] The temperature Q is compared with the preset temperature Q 预设 Compare: If Q < Q 预设 , control the atomization mechanism 40 to work; if Q ≥ Q 预设 , controlling the atomizing mechanism 40 to stop working can avoid damage to the atomizing mechanism 40 caused by working in a high temperature environment, and ensure a longer service life of the atomizing mechanism 40.

[0118] After the step of controlling the atomizing mechanism 40 to work, the step further includes: comparing the liquid level H with the preset liquid level H 预设 Compare: If H≤H 预设 , control the atomization mechanism 40 to stop working; if H>H 预设 , then return to the step of determining whether the flue 5000 is in working state. The atomizing mechanism 40 only atomizes the liquid with a higher liquid level H. The atomizing mechanism 40 does not need to be started for a long time, and is only started when the liquid level H is high enough, which can effectively reduce the energy consumption and working self-consumption of the atomizing mechanism 40 and the cooking device 1000, and effectively increase the service life of the atomizing mechanism 40 and the cooking device 1000.

[0119] The control method of the disclosed embodiment first determines whether Q<Q 预设 Make a judgment, if Q<Q 预设 , the atomizing mechanism 40 can be controlled to work first, so as to achieve timely response of the atomizing mechanism 40 while ensuring a long service life of the atomizing mechanism 40, thereby avoiding the problem of excessive liquid in the box body 10 caused by the slow response of the atomizing mechanism 40.

[0120] Embodiment 5

[0121] The present disclosure provides a control method, which is a further refinement of the control method disclosed in the third embodiment. Fig. 9As shown, the main difference between this control method and the control method of the second embodiment is that the steps of controlling the working state of the atomizing mechanism 40 according to the liquid level H and / or the temperature Q are specifically:

[0122] Determine whether H>H is satisfied at the same time 预设 and Q<Q 预设 When the two conditions are met, the atomization mechanism 40 can be controlled to work only when the above two conditions are met at the same time, which can effectively reduce the low energy consumption of the atomization mechanism 40 and the cooking device 1000, and effectively increase the service life of the atomization mechanism 40.
