The control valve 221 is controlled by the main control structure to realize automatic water supply to the water storage box 21. The water supply to the water storage box 21 is detected by the flow detection element 222, so that appropriate water replenishment can be achieved to avoid safety accidents caused by overflow of the water storage box 21. The main control structure can memorize the water replenishment time, and can ensure normal water filling of the water storage box 21 when the flow detection element 222 is damaged. Multiple water replenishment can be realized by turning the control valve 221 on and off, and can ensure stable water supply from the water storage box 21 to the steam generating element 3, thereby improving the stability of the cooking process. The structure is simple and the use effect is good.

[0054] like Figure 1-Figure 8 As shown, a cooking device 100 according to an embodiment of the present invention includes: a device body 1, a steam generating element 3, a water supply component 2 and a main control structure.

[0055] A cooking cavity 14 is formed in the device body 1. Specifically, the cooking device 100 can be other types such as an air fryer, a steam oven, and a baking oven. The device body 1 is a shell structure of the cooking device 100, which includes a cooking cavity 14 inside. The cooking cavity 14 is used to place food to be cooked, and food is cooked in the cooking cavity 14.

[0056] The steam generator 3 is installed on the device body 1, and the steam generator 3 is used to transport steam to the cooking cavity 14. Specifically, the steam generator 3 is detachably connected to the device body 1. A heating element can be provided inside the steam generator 3 to heat the water in the steam generator 3 to form steam, and the steam outlet end of the steam generator 3 can be connected to the cooking cavity 14 through a delivery pipe or a delivery tube to transport the generated steam to the cooking cavity 14 to steam food.

[0057] The water supply assembly 2 includes a water storage box 21, a water inlet pipe 22 and a water outlet pipe 23. The water inlet pipe 22 and the water outlet pipe 23 are respectively connected to the water storage box 21. The water inlet pipe 22 is suitable for being connected to a water source. A control valve 221 and a flow detection element 222 are provided in the water inlet pipe 22. The water outlet pipe 23 is connected to the water inlet 211 of the steam generating element 3. The control valve 221 and the flow detection element 222 are respectively electrically connected to the main control structure. The main control structure is used to control the on and off of the control valve 221.

[0058] Specifically, the water storage box 21 is used to store purified water, and the water inlet pipe 22 and the water outlet pipe 23 can be configured as connecting water pipes, wherein one end of the water inlet pipe 22 can be connected to the water storage box 21 through a connecting joint 24, and the other end of the water inlet pipe 22 is connected to a water source, so that the water source can be introduced into the water storage box 21 through the water inlet pipe 22 to achieve water filling of the water storage box 21, wherein the water source can be a water supply device such as a water purifier, which can provide clean and safe water quality for the cooking device 100. One end of the water outlet pipe 23 can be connected to the water storage box 21 through a connecting joint 24, and a water inlet and a steam outlet are provided at the end of the steam generating part 3, and the other end of the water outlet pipe 23 is connected to the water inlet of the steam generating part 3, so that the water in the water storage box 21 can be supplied to the steam generating part 3.

[0059] A control valve 221 and a flow detection element 222 are provided in the water inlet pipeline 22. The control valve 221 can be a solenoid valve, etc., for controlling the on-off of the water inlet pipeline 22. The flow detection element 222 can be a flow meter, for detecting and recording the water injection amount of the water storage box 21. Both are electrically connected to the main control structure to control the control valve 221 and the flow detection element 222 to work selectively through the main control structure.

[0060] Furthermore, in the steam mode, the water box 21 needs to be filled with water, the main control structure controls the control valve 221 to open, the water inlet pipe 22 is connected to the water box 21, and water is supplied to the water box 21. At the same time, the flow detection element 222 detects the amount of water supplied to the water box 21. When the flow detection element 222 detects that the amount of water in the water box 21 is sufficient, the main control structure controls the control valve 221 to close and stop the water supply, and the flow detection element 222 stops working. When the amount of water in the water box 21 is insufficient, the above operation continues to be performed to complete the next filling of the water box 21 to ensure the stability of steamed food. The main control structure can record the filling time of the water box 21 each time, that is, when the flow detection element 222 is damaged, the main control structure can determine the amount of water injected by the memorized filling time to ensure the normal filling of the water box 21.

[0061] Therefore, by setting the water storage box 21, water from the water source can be stored in the water storage box 21 in advance, and the water storage box 21 provides clean water for the steam generating part 3, and the main control structure controls the opening of the control valve 221 to realize automatic water supply to the water storage box 21. In this way, there is no need to manually monitor the water volume of the water storage box 21 and manually add water, which reduces the labor cost and the phenomenon of human negligence, so as to ensure that the water storage box 21 stably supplies water to the steam generating part 3, and ensure that the steam generating part 3 stably generates steam to ensure the continuity and cooking effect of cooking. In addition, by setting the flow detection element 222, the problem of overflowing the water storage box 21 will not be caused, and water can be replenished in an appropriate amount, so as to ensure that too much water will not be deposited, reduce the risk of water deterioration, and improve the quality of water use. In addition, by setting the water storage box 21, when the water source is repaired or damaged, the user can still use the water storage box 21 water supply method to supply water to the steam generating part 3 normally to ensure the normal cooking of the cooking device 100, and the overall structure has a wider range of application and higher reliability.

[0062] According to the cooking device 100 of the embodiment of the present invention, a control valve 221 and a flow detection element 222 are set in the water inlet pipe 22, and the control valve 221 is controlled by the main control structure to realize automatic water supply to the water storage box 21, and the water supply to the water storage box 21 is detected by the flow detection element 222, so that appropriate water replenishment can be achieved to avoid the water storage box 21 overflowing and causing a safety accident, and the main control structure can memorize the water replenishment time, and can ensure the normal water filling of the water storage box 21 when the flow detection element 222 is damaged, and multiple water replenishment can be achieved by turning the control valve 221 on and off, which can ensure that the water storage box 21 stably supplies water to the steam generating element 3, thereby improving the stability of the cooking process, and the structure is simple and the use effect is good.

[0063] In some embodiments, the device body 1 is further formed with an installation cavity 11, and the installation cavity 11 is distributed separately from the cooking cavity 14. Specifically, the installation cavity 11 is used to install other structures of the cooking device 100, and the installation cavity 11 and the cooking cavity 14 are distributed separately, wherein the cooking cavity 14 can be located in the middle area of ​​the device body 1, and a large amount of space of the device body 1 can be used to hold food for cooking food. The installation cavity 11 can be located on the side of the cooking cavity 14, and the installation cavity 11 can also be located on the top of the cooking cavity 14. In this way, the structure in the installation cavity 11 can be separated from the cooking cavity 14 to reduce the occupation of the cooking cavity 14 by other structures, thereby realizing the reasonable arrangement of the internal structure of the device body 1.

[0064] The steam generating element 3 is installed in the installation cavity 11 , the water supply assembly 2 is located in the installation cavity 11 , and at least a portion of the water inlet pipeline 22 extends out of the equipment body 1 .

[0065] Specifically, the steam generating element 3 is detachably connected to the installation cavity 11, and the various components of the water supply assembly 2 are detachably connected to the installation cavity 11. The connection method is simple and convenient for assembly and maintenance. Figure 1 As shown, at least part of the water inlet pipe 22 passes through the device body 1 and extends to the outside of the device body 1 to be connected to an external water source. At least part of the water inlet pipe 22 is located in the installation cavity 11 and is connected to the water storage box 21. In this way, external purified water can be introduced into the water storage box 21 through the water inlet pipe 22, and the connection between the water inlet pipe 22 and the device body 1 can be fixedly connected by a pipe joint, etc., and the water inlet pipe 22 can be fixed to ensure stable water supply of the water inlet pipe 22.

[0066] Therefore, the water supply component 2 and the steam generator 3 are both arranged in the installation cavity 11, and the space of the installation cavity 11 can be used to arrange various structures, and the external water source is introduced into the steam generator 3 through the water supply component 2, and the steam generated by the steam generator 3 is then transported to the cooking cavity 14, so that food can be steamed.

[0067] In some embodiments, the water inlet pipe 22 includes an internal pipe 223 and an external pipe 224, and the internal pipe 223 and the external pipe 224 are connected by a connecting joint 24, and the connecting joint 24 is passed through the side wall of the installation cavity 11. The internal pipe 223 is located in the installation cavity 11 and connected to the water storage box 21, and the external pipe 224 is located outside the equipment body 1 and connected to the water source.

[0068] Specifically, the connection joint 24 is a connection element, and the connection joint 24 can be penetrated through the side wall of the installation cavity 11. The two can be connected by means of threads, clamping, etc., and the connection is reliable and stable, avoiding the shaking of the connection joint 24, and improving the reliability of the water connection. The internal pipeline 223 and the external pipeline 224 can be constructed as connecting water pipes, and the two ends of the external pipeline 224 and the internal pipeline 223 are respectively connected to the connection joint 24, which can realize the communication between the internal pipeline 223 and the external pipeline 224 to realize the inflow of water. The internal pipeline 223 is located in the installation cavity 11, the water outlet end of the internal pipeline 223 is connected to the water storage box 21, the external pipeline 224 is located outside the device body 1, and the water inlet end of the external pipeline 224 is connected to the water source. In this way, the water at the water source flows into the water storage box 21 through the external pipeline 224 and the internal pipeline 223 in sequence, so as to realize the water filling of the water storage box 21.

[0069] Therefore, by setting the connecting joint 24, the internal pipeline 223 and the external pipeline 224 can be connected to the equipment body 1 through the connecting joint 24, and the connecting joint 24 has good sealing performance, which can prevent water leakage or external pollutants from entering the water inlet pipeline 22, thereby ensuring the stability and safety of the water inlet pipeline 22. The installation and maintenance of the connecting joint 24 are simpler and more convenient, and the operating flexibility is high. There are many types of connecting joints 24, and the adaptability is stronger.

[0070] In some embodiments, the control valve 221 and the flow detection element 222 are spaced apart and distributed in the internal pipeline 223 along the water flow direction. Figure 1 and Figure 2 As shown, the water flow direction is from the external pipeline 224 to the internal pipeline 223 and then to the water storage box 21. The control valve 221 is located upstream of the flow detection element 222. The control valve 221 controls the water flow of the water inlet pipeline 22. The flow detection element 222 detects the amount of water injected into the water storage box 21 by the water inlet pipeline 22. In this way, during the water supply process, the water flows through the control valve 221 and the flow detection element 222 in sequence to the water storage box 21. When the flow detection element 222 detects that the water supply to the water storage box 21 is sufficient, the control valve 221 is closed, the water flow of the water inlet pipeline 22 is disconnected, and the water supply to the water storage box 21 is stopped. The flow detection element 222 is arranged downstream of the control valve 221, which can ensure that the control valve 221 is closed after the water supply is sufficient, thereby improving the accuracy of the water supply to the water storage box 21 and ensuring that the water supply to the water storage box 21 tends to be stable each time.

[0071] In some embodiments, the connecting joint 24 includes a first joint section 241 and a second joint section 242, the first joint section 241 is connected to the second joint section 242 by bending, the internal pipeline 223 is connected to the first joint section 241, the external pipeline 224 is connected to the second joint section 242, and the external pipeline 224 extends in a direction parallel to the side wall of the installation cavity 11 where the connecting joint 24 is located.

[0072] Specifically, the first joint section 241 and the second joint section 242 are connected by bending, and the bending angle may be a right angle, such as Figure 1 and Figure 2 As shown, the connecting joint 24 can be constructed as a right-angle pipe joint, wherein the end of the first joint section 241 is the water outlet end, and the end of the second joint section 242 is the water inlet end, and the water inlet end is connected to the external pipeline 224, and the water outlet end is connected to the internal pipeline 223, and the second joint section 242 is parallel to the side wall of the installation cavity 11 where it is located, and the external pipeline 224 can extend in a direction parallel to the first joint section 241. The arrangement method is diverse and can be adjusted according to actual needs.

[0073] Therefore, by setting the first joint section 241 and the second joint section 242 to be bent and connected, the flow direction of the purified water can be changed to adapt to the spatial layout requirements, and the external pipeline 224 extends parallel to the side wall of the installation cavity 11, which can save space, and the water pipe length of the external pipeline 224 is shorter, which reduces the water flow path and can improve the water supply efficiency of the water inlet pipeline 22 to the water storage box 21.

[0074] In some embodiments, at least a portion of the installation cavity 11 is located above the cooking cavity 14 and is formed as a top sub-cavity 111 , and the water supply assembly 2 is disposed in the top sub-cavity 111 .

[0075] Specifically, the installation cavity 11 is distributed outside the cooking cavity 14. Figure 1 As shown, at least part of the installation cavity 11 is a top sub-cavity 111, which is located above the cooking cavity 14, and the inner wall of the top sub-cavity 111 is used for the installation of the water supply component 2, wherein the control valve 221, the water storage box 21 and other structures of the water supply component 2 can be detachably connected to the top sub-cavity 111, and the connecting joint 24 can be connected to the rear side wall of the top sub-cavity 111, so that water can be introduced into the water supply component 2 from the rear top, avoiding the external pipeline 224 from being exposed to the field of vision, which conforms to the appearance layout of the cooking device 100.

[0076] Thus, the water supply component 2 can occupy the space of the top sub-cavity 111 above the cooking cavity 14, and the water storage box 21 occupies a larger space, which can increase the water storage capacity, and the water inlet pipe 22 and the water outlet pipe 23 occupy a smaller space, which can improve the overall water supply efficiency. Its layout is reasonable and the overall structure is compact, which is conducive to the integrated setting of multiple functions of the cooking equipment 100.

[0077] In some embodiments, there are two control valves 221 , one is a main control valve and the other is a backup control valve. The main control valve and the backup control valve are electrically connected to the main control structure respectively, and the main control valve and the backup control valve are separated and distributed in the water inlet pipeline 22 .

[0078] Specifically, the main control valve and the backup control valve are spaced apart and distributed, and both are connected to the water inlet pipe 22. Opening or closing one of the main control valve and the backup control valve can realize the on-off of the water flow in the water inlet pipe 22, and the main control valve and the backup control valve are electrically connected to the main control structure respectively, and the on-off of the main control valve and the backup control valve are controlled by the signal of the main control structure.

[0079] Furthermore, when both control valves 221 function normally and when water needs to be supplied to the water storage box 21, the main control structure sends an opening signal to control the main control valve to open, so that the water inlet pipeline 22 can supply water to the water storage box 21, and after the water supply is sufficient, the main control structure sends a closing signal to control the main control valve to close, so as to stop supplying water to the water storage box 21. After the main control valve is damaged, the main control structure can control the opening and closing of the standby control valve to also realize water supply.

[0080] Therefore, by setting up a double control valve 221, the safety of the water inlet pipe 22 can be increased, and it can prevent one of the control valves 221 from being damaged and unable to control the water flow of the water inlet pipe 22, thereby preventing safety accidents caused by overflowing of the water storage box 21. Moreover, by controlling the control valve 221 through the main control structure, the water flow interruption state of the water inlet pipe 22 can be switched flexibly, and the safety of use is high.

[0081] In some embodiments, the cooking device 100 further includes a water pump 25, which is disposed in the water outlet pipeline 23. Specifically, the water pump 25 is used to pump water, and the water pump 25 is connected to the water outlet pipeline 23. The water pump 25 is detachably connected to the installation cavity 11, and the downstream of the water pump 25 is connected to the steam generating element 3, and the water pump 25 can be electrically connected to the main control structure, and the main control structure controls the working state of the water pump 25. Different cooking requirements and corresponding preset programs are set in the main control structure. When the user selects the steaming mode, the water supply Component 2 is started and the water pump 25 is turned on. The clean water in the water storage box 21 can be passed into the water inlet 211 of the steam generating element 3 through the water pump 25, and the steam generating element 3 transports steam toward the cooking chamber 14 to cook food. After the food is steamed, the main control structure controls the steam generating element 3 and the water pump 25 to be turned off, and in other cooking modes, the main control structure controls both the water pump 25 and the steam generating element 3 to be turned off, so that the cooking device 100 can selectively start different cooking modes, making the cooking device 100 more convenient to use.

[0082] In some embodiments, the water storage box 21 is provided with a water inlet 211 and a water outlet 212 , the water inlet 211 is connected to the water inlet pipeline 22 , and the water outlet 212 is connected to the water outlet pipeline 23 .

[0083] Specifically, the water inlet 211 is used for water inlet to the water storage box 21, and the water outlet 212 is used for water outlet from the water storage box 21. The water inlet pipe 22 can be connected with the water storage box 21 through the water inlet 211, that is, the water in the water inlet pipe 22 flows into the water storage box 21 from the water inlet 211, and the water storage box 21 can be connected with the water outlet pipe 23 through the water outlet 212, that is, the water in the water storage box 21 flows into the water outlet pipe 23 from the water outlet 212. Among them, the water inlet and outlet of the water storage box 21 can be carried out at the same time, and the water flow in the water storage box 21 can only flow in and not out, or only flow out and not in for a period of time, and its working state can be selected according to the actual water supply demand.

[0084] Among them, the water inlet 211 and the water outlet 212 are arranged on the same side of the water storage box 21 and are distributed in parallel and spaced apart, that is, the water inlet 211 and the water outlet 212 are both arranged on the same side of the water storage box 21, and they are arranged in parallel and spaced apart. In this way, water inlet and water outlet can be achieved on the same side of the water storage box 21, and the connection points of the water inlet pipe 22 and the water outlet pipe 23 with the water storage box 21 are centrally arranged, which makes installation and maintenance more convenient. In addition, arranging the water inlet 211 and the water outlet 212 on the same side can save space, making the water storage box 21 more compact, which is conducive to providing more installation space for other structures.

[0085] In some embodiments, the device body 1 includes a rear housing 12 and a front door panel 13, and the front door panel 13 can be installed on the front side of the rear housing 12 to open or close the cooking cavity 14. Specifically, Figure 1As shown, the device body 1 includes a front door panel 13 and a rear shell body 12, the front door panel 13 is located at the front side of the rear shell body 12, and the front door panel 13 can be installed on the device body 1 in an openable and closable manner. The user can open or close the cooking cavity 14 by operating the opening and closing of the front door panel 13, which is convenient for the user to access the cooking cavity 14 and put in and take out food, and the steam generating element 3 is detachably connected to a side of the rear shell body 12 close to the front door panel 13. When steaming food, the user opens the front door panel 13 and puts the food to be cooked into the cooking cavity 14, and the water source enters the water supply component 2 and the steam generating element 3 from one side of the rear shell body 12 to realize steam production, and then the steam is transported to the cooking cavity 14 to steam the food. After cooking, the front door panel 13 is opened again to take out the food.

[0086] The device body 1 further includes a display structure 15 connected to the rear housing 12 . The display structure 15 is located on the top of the front door plate 13 . The display structure 15 is electrically connected to the main control structure.

[0087] Specifically, the display structure 15 is used to display the cooking mode, dish information, etc. to the user. For example, the display structure 15 can be a display screen. The display structure 15 can include a display panel and related control circuits, wherein, for example Figure 1 As shown, the display structure 15 is connected to the rear housing 12. The display structure 15 can be detachably connected to the rear housing 12 by fasteners such as bolts, or the display structure 15 can be connected to the rear housing 12 by snapping. The connection methods are diverse and simple. The display structure 15 and the front door panel 13 are located on the same side of the device body 1, and the display structure 15 is located on the top of the front door panel 13, which can avoid interference between the display structure 15 and the front door panel 13. The display structure 15 is electrically connected to the main control structure, so that data transmission and control signal exchange can be performed between the two, that is, the information display of the display structure 15 can be controlled by the main control structure.

[0088] Among them, the main control structure can receive user input, process data and control the operation of the device. It may include a microcontroller, a circuit board and other electronic components. In this way, when the user uses the cooking device 100, the main control structure receives the user's power-on request, and the main control structure controls the display structure 15 to display, so that the user can view the status, settings and feedback information of the cooking device 100.

[0089] Therefore, by arranging the display structure 15 at the top of the front door panel 13, it is easier for the user to view information during operation, thereby improving the convenience of operation.

[0090] The present invention also provides a control method of the cooking device 100 .

[0091] According to the control method of the cooking device 100 of the embodiment of the present invention, the control method includes:

[0092] S1: Obtain the cooking mode of the cooking device 100, wherein the cooking device 100 of this embodiment may include multiple cooking modes, and the cooking modes include frying mode, baking mode, steaming mode, etc. After the user selectively confirms a cooking mode, the cooking device 100 performs the next control operation.

[0093] S2: When the cooking mode of the cooking device 100 is the steam mode, the cooking cavity 14 is controlled to be preheated. That is, when the user confirms to use the steam mode, the main control structure of the cooking device 100 can control the cooking cavity 14 to be preheated, that is, to heat the cooking cavity 14.

[0094] In the steam mode, the cooking cavity 14 is first controlled to be preheated, that is, before starting cooking, the cooking cavity 14 is heated to a set temperature so that the inside of the cooking cavity 14 is at a relatively high temperature. In this way, the phenomenon of condensation of steam entering the cooking cavity 14 can be avoided, thereby improving the steaming effect of food and enhancing the taste of food. Moreover, steam entering the cooking cavity 14 with high heat can steam food faster, improve the utilization rate of steam, and improve the cooking efficiency of food. The preheating of the cooking cavity 14 can heat the air inside it through the heating tube.

[0095] S3: After the cooking cavity 14 is preheated, the current state of the steam generating element 3 is monitored, that is, after the preheating of the cooking cavity 14 is completed, the current state of the steam generating element 3 is monitored, and the current state is the internal environment of the steam generating element 3, that is, it can be detected whether the steam generating element 3 is normally producing steam, and the next operation step is performed according to the current state of the steam generating element 3. By detecting the current state of the steam generating element 3, the safe operation of the steam generating element 3 can be guaranteed, and the service life of the steam generating element 3 can be increased.

[0096] S4: When the current state of the steam generating element 3 is a dry-burning state, the water inlet pipe 22 is controlled to supply water to the water storage box 21. That is, when it is monitored that the steam generating element 3 is in a dry-burning state, and the dry-burning state indicates that there is no water in the steam generating element 3, it can be determined that the water storage box 21 is in a water shortage state. Then, the water inlet pipe 22 can be controlled to supply water to the water storage box 21, and the steam generating element 3 can be controlled to be closed, so as to avoid deformation, damage and other serious consequences caused by long-term dry-burning of the steam generating element 3, and reduce the cooking efficiency of food.

[0097] S5: Detect the water volume of the water storage box 21, and when the water volume is greater than the set water volume, control the water inlet pipeline 22 to stop supplying water and control the steam generating element 3 to work, that is, after the water inlet pipeline 22 supplies water to the water storage box 21, the water volume of the water storage box 21 can be detected in real time through the flow detection element 222 of the water inlet pipeline 22, and when the water volume is greater than the set water volume, control the control valve 221 of the water inlet pipeline 22 to close, stop supplying water to the water storage box 21, and control the steam generating element 3 to open, so that the steam generating element 3 works normally to generate steam. Among them, the set water volume is less than the maximum water storage volume of the water storage box 21, so that the above-mentioned settings can reduce the safety accidents caused by the overflow of the water storage box 21.

[0098] Thus, through Figure 3 The control method of steps 1 to 5 shown can timely monitor whether the water storage box 21 is short of water, and when the water storage box 21 is short of water, timely control the water inlet pipe 22 to supply water to the water storage box 21, so as to ensure that the water volume of the water storage box 21 is sufficient to supply water to the steam generating part 3, avoid the dry burning of the steam generating part 3, improve the safety, reliability and stability of the steam mode operation process, and improve the steaming efficiency of food, and by setting the set water volume, the water storage box 21 can be properly replenished, the water storage rate of the water storage box 21 can be reduced, and the risk of water deterioration can be reduced. In addition, the entire control process has a high degree of automation, which saves the manual water replenishment workload and reduces labor costs.

[0099] In some embodiments, the control method further comprises:

[0100] S6: When the current state of the steam generating element 3 is a non-dry-burning state, the steam generating element 3 is controlled to work, and the current state of the steam generating element 3 is continuously detected.

[0101] That is to say, when it is monitored that the steam generating element 3 is in a non-dry-burning state, and the non-dry-burning state indicates that there is water in the steam generating element 3, it can be determined that the water storage box 21 is in a non-water-deficient state, and the steam generating element 3 can be controlled to work.

[0102] Specifically, in actual use, when the steam generating element 3 is last monitored to be in a dry-burning state, the water inlet pipe 22 supplies water to the water storage box 21, and when the water storage box 21 is supplied with sufficient water, the water storage box 21 supplies water to the steam generating element 3 through the water outlet pipe 23, and when the steam generating element 3 is detected to be in a non-dry-burning state again, the steam generating element 3 can be controlled to switch from a closed state to an open state, and when the steam generating element 3 is working normally, the water in the water storage box 21 will gradually decrease, and it is necessary to continuously detect the current state of the steam generating element 3 in order to effectively and timely execute different control methods. With this arrangement, the control method is safer and the safety of the steam generating element 3 is ensured.

[0103] Thus, through Figure 4 and Figure 7The control method can determine the current situation of the steam generating element 3, perform the next step of controlling the steam generating element 3, and realize monitoring of different states of the steam generating element 3 to achieve steaming of food and protection of the cooking device 100.

[0104] In some embodiments, the control method further comprises:

[0105] S41: After controlling the water inlet pipe 22 to supply water to the water storage box 21 , detecting the water inlet time of the water inlet pipe 22 , that is, the water supply time of the water inlet pipe 22 to the water storage box 21 can be detected.

[0106] S42: When the water inlet time exceeds the first set time and the flow rate of the water inlet has not reached the set water volume, it is determined that the flow detection element 222 used to detect the water inlet is faulty. That is to say, when the detected water inlet time exceeds the first set time, the water inlet detected by the flow detection element 222 is compared and analyzed with the set water volume. When the flow rate of the water inlet reaches the set water volume, it can be determined that the flow detection element 222 is functioning normally. On the contrary, when the flow rate of the water inlet does not reach the set water volume, it can be determined that the flow detection element 222 is functioning abnormally and is faulty.

[0107] In actual use, the water storage box 21 is provided with a set water volume, that is, when the water inlet pipe 22 supplies water to the water storage box 21, the flow detection element 222 detects the water volume from the start of water supply to the stop of water supply, and it takes a certain time for the water inlet pipe 22 to provide enough set water volume to the water storage box 21, and the corresponding time is the first set time. Then, by Figure 5 According to the control method in the invention, the main control structure of the cooking device 100 records the water inlet time each time. When the water inlet time exceeds the first set time and the flow rate of the water inlet detected by the flow detection element 222 is less than the set water volume, the flow detection element 222 is determined to be faulty. At this time, the water inlet time exceeds the first set time and the water supply of the water storage box 21 is sufficient. The water supply of the water inlet pipe 22 to the water storage box 21 can be stopped. In this way, it can be avoided that the water inlet pipe 22 continues to supply water to the water storage box 21, causing safety accidents such as overflow of the water storage box 21. The control method can timely and effectively change the control strategy, thereby improving the stability and safety of the use of the cooking device 100.

[0108] At the same time, after the water supply is stopped, the current state of the steam generating element 3 can be detected, and then the next step can be selectively executed to ensure the reliability of the control process of the control method.

[0109] Therefore, by setting the first set time, it is possible to determine whether the function of the flow detection element 222 is normal, and to understand the current state of the water supply component 2, which is conducive to selecting different execution steps. The control method is reasonable and safe, thereby improving the cooking effect of the cooking device 100.

[0110] In some embodiments, the control method further comprises:

[0111] S43: After controlling the water inlet pipe 22 to supply water to the water storage box 21 , detecting the water inlet time of the water inlet pipe 22 , that is, the water supply time of the water inlet pipe 22 to the water storage box 21 can be detected.

[0112] S44: When the water inlet time exceeds the second set time and the steam generating element 3 is still in a dry-burning state, it is determined that the control valve 221 used to control the water inlet pipe 22 is faulty; and, when the detected water inlet time exceeds the second set time and it is monitored that the steam generating element 3 is not in a dry-burning state, it can be determined that the function of the control valve 221 is normal.

[0113] Specifically, the second set time is the time when the water inlet pipe 22 starts to supply water to the water storage box 21 when the water storage box 21 is short of water. The second set time can be set to 5 seconds. Then, by Figure 6 In the control method, after the water storage box 21 is short of water, the water inlet pipe 22 is controlled to supply water to the water storage box 21. After the control signal is sent and the water inlet time exceeds 5 seconds, the monitored steam generating element 3 is in a non-dry-burning state, that is, the water inlet pipe 22 normally supplies water to the water storage box 21, and the control valve 221 is not damaged. On the contrary, when the water inlet time exceeds 5 seconds and the monitored steam generating element 3 is in a dry-burning state, the water storage box 21 is still short of water, that is, the water inlet pipe does not supply water to the water storage box 21, and it can be determined that the control valve 221 is faulty. In this way, if water is not replenished in time after the control valve 221 fails, the water shortage fault can be displayed through the display structure 15, and the steam generating element 3 is controlled to be closed, and the cooking device 100 is repaired.

[0114] The second set time may also be 4 seconds, 6 seconds, etc., and may be selectively set according to the actual length of the water inlet pipeline 22 or other requirements.

[0115] Therefore, by setting the second set time, it is possible to determine whether the control valve 221 functions normally, which can reduce the possibility of continuous dry burning of the steam generating element 3 to avoid more serious damage. The control method is perfect and safe, thereby improving the cooking effect of the cooking device 100.

[0116] In some embodiments, the control method further comprises:

[0117] S41: After controlling the water inlet pipe 22 to supply water to the water storage box 21 , detecting the water inlet time of the water inlet pipe 22 , that is, the water supply time of the water inlet pipe 22 to the water storage box 21 can be detected.

[0118] S45: When the water inlet time exceeds the third set time and the flow rate of the water inlet has not reached the set water volume, stop the water supply, wherein the third set time is determined according to the recipe for each cooking.

[0119] In actual use, the third set time is the time required for the water inlet pipe 22 to provide an appropriate amount of water to the water storage box 21 under the cooking conditions of different foods and dishes. That is, the flow rate of the water inlet can be set to change accordingly according to the different cooking methods of different foods and dishes. The main control structure of the cooking device 100 is set with the flow rate of the water inlet corresponding to the cooking methods of different foods and dishes, which can be differentially controlled by the water inlet time, and the third set time can be: 3 seconds, 4 seconds, 5 seconds, etc.

[0120] In this way, through Figure 8 The control method shown controls the water inlet pipe 22 to supply water to the water storage box 21 after the water storage box 21 is short of water. When the control signal is sent and it is detected that the water inlet time exceeds the third set time, the water inlet amount detected by the flow detection element 222 is compared and analyzed with the set water amount. When the flow rate of the water inlet does not reach the set water amount, the water supply is stopped and the steam generating element 3 can work normally.

[0121] Therefore, by setting the third set time, the water flow rate of the water storage box 21 can be controlled to be more appropriate, which can adapt to the cooking mode that requires more steam or less steam, and can avoid the water flow rate of the water storage box 21 being too much or too little, and can achieve quantitative water supply to meet the cooking needs of different food ingredients. It can also reduce the occurrence of sedimentation water, thereby improving the quality of cooking, and has multiple functions, better use effects, and better cooking taste of food.
