[0002] Existing cooking appliances discharge a large amount of steam during the cooking process. The high-temperature and high-humidity steam will cause the temperature and humidity of the narrow kitchen environment to increase, making the kitchen become humid.

In related technologies, a water tank can be set to discharge the steam into the water tank to condense into water to avoid the outward emission of steam. However, during the cooking process, as the steam is discharged into the water tank, the time for the water tank to condense the steam is prolonged, and the condensation efficiency drops significantly.

[0087] This application provides a cooking appliance 100.

[0088] With reference to Figure 3 and Figure 4 , in some embodiments of this application, the cooking appliance 100 includes an appliance main body 10, a condensation module 30, and a water pumping module 50. The appliance main body 10 includes a pot body 11 and a lid body 13. The pot body 11 is provided with a cooking space 111, and the lid body 13 is provided with a communication channel 131; the condensation module 30 is arranged on the appliance main body and is provided with a condensation cavity 311, and the condensation cavity 311 is communicated with the cooking space 111 through the communication channel 131; the water pumping module 50 is communicated with the condensation cavity 311 to make the condensation cavity 311 intake and drain water.

[0089] The cooking appliance 100 proposed in the present application may be, but is not limited to, a rice cooker, a steam box, a steam oven, and other appliances that generate steam during the cooking process. The appliance body 10 of the cooking appliance 100 includes a pot body 11 and a lid body 13. A cooking space 111 for placing and cooking food ingredients is formed inside the pot body 11. The pot body 11 may include an outer shell and an inner pot, and the inner pot forms the cooking space 111. The heating structure may be disposed between the outer shell and the inner pot. The lid body 13 is pivotally mounted on the pot body 11 and is provided with a communication channel 131. When the lid body 13 is closed on the pot body 11, the air inlet 313 of the communication channel 131 communicates with the cooking space 111. In addition, the cooking appliance 100 further includes a condensation module 30. The condensation module 30 may be disposed on the lid body 13, may be disposed on the pot body 11, or may be independently disposed of the lid body 13 and the pot body 11. The condensation module 30 has a water tank 31. A condensation chamber 311 is provided inside the water tank 31, and the outlet 135 of the communication channel 131 can communicate with the condensation chamber 311 at least when the lid body 13 is closed on the pot body 11. The outlet 135 of the communication channel 131 may also communicate with the condensation chamber 311, so that the steam generated during the cooking process of the cooking appliance 100 can flow into the condensation chamber 311 through the communication channel 131. When using the cooking appliance 100 and selecting a cooking mode with no steam or micro-steam emission, cooling water may be stored in the condensation chamber 311 first. The steam generated in the cooking space 111 flows into the condensation chamber 311 through the communication channel 131 and contacts the cooling water to condense into water, reducing or avoiding the discharge of steam to the outside of the cooking appliance 100, achieving the purpose of micro-steam or no-steam emission during the cooking process, thereby avoiding the influence of steam on the surrounding environment and avoiding scalding the user with steam. When the steam enters the condensation chamber 311 for condensation, the heat carried by it is transferred to the water in the condensation chamber 311, which will cause the water temperature of the cooling water in the condensation chamber 311 to rise. The condensation effect of the steam in the condensation chamber 311 is related to the water temperature of the cooling water. If the water temperature is too high, the condensation effect will be affected.

[0090] In an embodiment of the present application, a water pumping module 50 is further provided in the cooking appliance 100. The water pumping module 50 can be used to fill and drain the condensation chamber 311 to adjust the water temperature in the condensation chamber 311; keep the water temperature in the condensation chamber 311 within a preset temperature range or keep the water temperature change amount per unit time within a preset range; prevent the water temperature of the cooling water in the condensation chamber 311 from being too high or the cooling water from heating up too fast, so that the steam has a high condensation efficiency after entering the cooling water, so that as much steam as possible generated during the cooking process is condensed, reducing the amount of steam discharged to the outside, and achieving the purpose of no-steam or micro-steam emission.

[0091] For example, the water pumping module 50 may include a water injection structure 51 and a drainage structure 53. Both the water injection structure 51 and the drainage structure 53 may include a water pump, or may be provided with a switching device such as a solenoid valve that can control the fluid flow rate. Among them, the water injection structure 51 can be connected to an external water source, and during the cooking process, the water injection structure 51 can be used to inject cold water from the external water source into the condensation chamber 311 to reduce the water temperature in the condensation chamber 311 or prevent the water temperature in the condensation chamber 311 from rising too fast due to the injection of steam, so that the steam has a high condensation efficiency after entering the condensation chamber 311.

[0092] The drainage structure 53 can drain the water in the condensation chamber 311 to the outside of the cooking appliance 100. It can not only drain the relatively hot water in the condensation chamber 311 to realize the replacement of the water in the condensation chamber 311 and improve the water temperature adjustment effect of the condensation chamber 311, but also prevent the water level in the condensation chamber 311 from overflowing or affecting the entry of steam into the condensation chamber 311 due to the continuous replenishment of external cold water and the condensation of steam into water, thus playing a role in adjusting the water volume in the condensation chamber 311. In addition, the water injection speed and flow rate into the condensation chamber 311 can be controlled by controlling the power of the water pump in the water injection structure 51 or the size of the channel opened by the solenoid valve, so as to adjust the water temperature adjustment speed and temperature adjustment range in the condensation chamber 311. Similarly, the drainage speed and flow rate of the condensation chamber 311 can be controlled by controlling the power of the water pump in the drainage structure 53 or the size of the channel opened by the solenoid valve, and the water temperature adjustment speed and temperature adjustment range in the condensation chamber 311 can also be adjusted.

[0093] In addition, the water injection structure 51 and the drainage structure 53 can independently control the opening time and closing time. The water injection structure 51 and the drainage structure 53 can be opened simultaneously to realize the cyclic replacement of the water in the condensation chamber 311. Of course, the water injection structure 51 and the drainage structure 53 can also operate in different time periods, and only the water injection structure 51 can be opened during water temperature adjustment. In some embodiments, the water injection structure 51 and the drainage structure 53 can be set as the same structure. For example, a positive and reverse double-cycle water pump is used as the water pumping module 50, and the positive and reverse rotation of the water pump is used to realize the water injection and drainage of the condensation chamber 311 at different time periods respectively. When the above water pumping module 50 is adopted, it can also be used to adjust the water volume in the condensation chamber 311.

[0094] In some embodiments, the water pumping module 50 may also be a water-cooling circulation structure. In the following embodiments, the water pumping module 50 includes a circulation water pump and water-cooling pipes. Both ends of the water-cooling pipes are communicated with the condensation chamber 311 to form a water circulation path. The circulation water pump provides power to discharge the water in the condensation chamber 311 into the water-cooling pipes, cool the water flowing into the water-cooling pipes, and then make the cooled water flow from the water-cooling pipes into the condensation chamber 311. In this way, it can also play a role in regulating the water temperature of the condensation chamber 311, avoiding the water temperature in the condensation chamber 311 from rising too fast due to the injection of steam, so that the steam has a high condensation efficiency after entering the condensation chamber 311. Among them, the power of the circulation water pump can also be controlled to control the flow rate of the cooling water in the condensation chamber 311 and the water-cooling pipes, so as to control the flow heat dissipation time of the cooling water in the water-cooling pipes, and control the regulation speed and temperature regulation range of the water temperature in the condensation chamber 311.

[0095] It should be noted that in the embodiments of the present application, after the water pumping module 50 is turned on, it is not completely to make the water temperature of the cooling water in the condensation chamber 311 drop. It can also only reduce the rising speed of the cooling water in the condensation chamber 311. For example, if there is more cold water added from the external water source or the heat dissipation efficiency of the water-cooling pipes is higher, the water temperature in the condensation chamber 311 may drop below the initial water temperature after the water pumping module 50 is turned on. If relatively less cold water is added or the heat dissipation efficiency in the water-cooling pipes is slower, the water temperature in the condensation chamber 311 will also rise. However, since the water pumping module 50 injects cold water into the condensation chamber 311, it plays a role in reducing the rising speed of the cooling water in the condensation chamber 311 at this time, avoiding the cooling water from rising too fast.

[0096] In the embodiments of the present application, the opening and closing conditions of the water pumping module 50 can be to turn on the water pumping module 50 and the heating structure simultaneously when starting the cooking program and turn them off after cooking ends. It can also be to control the opening or closing of the water pumping module 50 according to different stages of the cooking process. For example, taking the rice cooking process as an example, the rice cooking process generally includes a heating stage, a boiling stage, and a simmering stage. The main steam generation stage is during the boiling stage. At this time, the water pumping module 50 can be turned on to adjust the water temperature in the condensation chamber 311 when entering the boiling stage; turn off the water pumping module 50 after entering the simmering stage. It can also be to use a humidity sensor or other detection structures to detect whether there is steam in any of the cooking space 111 and the condensation chamber 311 to control the opening and closing of the water pumping module 50.

[0097] In addition, it is also possible to determine whether to turn on or off the water pumping module 50 by detecting the change in the water temperature in the condensation chamber 311. For example, when the water temperature of the cooling water in the condensation chamber 311 reaches a preset temperature, the water pumping module 50 is turned on to adjust and control the water temperature. Or it can be that when the water temperature of the cooling water in the condensation chamber 311 rises too fast within a unit time, the water pumping module 50 is turned on, and when the temperature rise is relatively gentle and does not reach the preset temperature value, the water pumping module 50 is turned off.

[0098] Therefore, it can be understood that in the technical solution of the present application, a water pumping module 50 is provided in the cooking appliance 100 for allowing water to enter and drain from the condensation chamber 311. With such a setting, it is possible to inject water with a lower temperature into the condensation chamber 311 during the cooking process to adjust the water temperature in the condensation chamber 311. For example, water with a lower external temperature can be injected into the condensation chamber 311, or the water in the condensation chamber 311 can flow out for heat dissipation and then flow back into the condensation chamber 311, so as to prevent the water temperature in the condensation chamber 311 from rising too fast due to the continuous injection of steam, and keep the water temperature in the condensation chamber 311 within a range suitable for steam condensation, so that the steam generated during the cooking process has a high condensation efficiency and can be quickly condensed after entering the condensation chamber 311, reducing or avoiding the outward discharge of steam, which is conducive to achieving the purpose of micro-steam or steam-free discharge during the cooking process.

[0099] Please refer to Figure 4 , in some embodiments of the present application, the water pumping module 50 includes:

[0100] A water injection structure 51, which is connected to the condensation chamber 311 and can be used to connect to a water source to inject water into the condensation chamber 311; and

[0101] A drainage structure 53, which is connected to the condensation chamber 311.

[0102] In this embodiment, the water pumping module 50 includes a water injection structure 51 and a drainage structure 53. The water injection structure 51 is connected to an external water source. The water injection structure 51 includes a water pump 511 and a water inlet pipe 513. One end of the water inlet pipe 513 is connected to the water source through the water pump 511, and the other end of the water inlet pipe 513 is connected to the condensation chamber 311. The water source can be an external water source or a standby water source provided on the cooking appliance 100. When the water injection structure 51 is started, the water pump 511 can inject cold water from the water source into the condensation chamber 311 to reduce the water temperature in the condensation chamber 311 or prevent the water temperature in the condensation chamber 311 from rising too fast due to the injection of steam, so that the steam has a high condensation efficiency after entering the condensation chamber 311. By controlling the power of the water pump, the speed and flow rate of water injection into the condensation chamber 311 can be controlled, thereby adjusting the adjustment speed and temperature adjustment range of the water temperature in the condensation chamber 311.

[0103] The drainage structure 53 includes a drain 531 and a drain pipe 533. One end of the drain pipe 533 communicates with the condensation chamber 311, and the other end communicates with the drain 531. When the drainage structure 53 is started, the drain 531 can drain the water in the condensation chamber 311 to the outside of the cooking appliance 100 via the drain pipe 533, discharge the relatively hot water in the condensation chamber 311, realize the replacement of the water in the condensation chamber 311, improve the water temperature adjustment effect of the condensation chamber 311; and also avoid the water level in the condensation chamber 311 being too high and overflowing or affecting the steam entering the condensation chamber 311 due to continuously supplementing external cold water and steam condensing into water, playing a role in adjusting the water volume in the condensation chamber 311. And by controlling the power of the drainage pump, the drainage speed and flow rate of the condensation chamber 311 discharging water to the outside can be controlled, so as to adjust the adjustment speed and temperature adjustment range of the water temperature in the condensation chamber 311. It should be noted that in this embodiment, the drainage structure 53 discharging the water in the condensation chamber 311 can be discharged into the external water source communicated with the water injection structure 51, or discharged to other collection structures or directly discharged into the sewer, etc.

[0104] In addition, the water injection structure 51 and the drainage structure 53 can independently control the opening time and closing time respectively, and the water injection structure 51 and the drainage structure 53 can be opened simultaneously, so as to realize the cyclic replacement of the water in the condensation chamber 311; of course, the water injection structure 51 and the drainage structure 53 can also operate in different time periods, and only the water injection structure 51 can be opened during the water temperature adjustment.

[0105] In some embodiments of the present application, the water pumping module 50 includes a circulating water pump and a water cooling pipe. The two ends of the water cooling pipe are respectively a water inlet end and a water outlet end, and both are communicated with the condensation chamber 311. The circulating water pump can discharge the water in the condensation chamber 311 and flow back to the condensation chamber 311 via the water cooling pipe.

[0106] In this embodiment, the water pumping module 50 is a water cooling circulation structure, including a circulating water pump and a water cooling pipe. The two ends of the water cooling pipe are respectively a water inlet end and a water outlet end, and both are communicated with the condensation chamber 311, so that the water pumping module 50 and the condensation chamber 311 form a water circulation path. When the water pumping module 50 is started, the circulating water pump provides power to discharge the water in the condensation chamber 311 into the water cooling pipe, and the water flowing into the water cooling pipe flows into the condensation chamber 311 after being cooled in the water cooling pipe; thus, it can also play a role in adjusting the water temperature of the condensation chamber 311, avoiding the water temperature in the condensation chamber 311 rising too fast due to the injection of steam, so that the steam has a high condensation efficiency after entering the condensation chamber 311. Among them, the power of the circulating water pump can be controlled to control the flow speed of the cooling water in the condensation chamber 311 and the water cooling pipe, so as to control the flow heat dissipation time of the cooling water in the water cooling pipe, and control the adjustment speed and temperature adjustment range of the water temperature in the condensation chamber 311.

[0107] In addition, the water-cooling pipes can be entirely arranged inside the cooking appliance 100, or part of the pipes can be exposed to the outside to dissipate the heat of the water in the water-cooling pipes to the outside. Additionally, the method of cooling the water in the water-cooling pipes can be natural heat dissipation, or auxiliary heat dissipation structures such as air-cooling heat dissipation structures and refrigerant heat dissipation structures can be provided on the water-cooling pipes.

[0108] Please refer to Figure 4 , in some embodiments of the present application, the water inlet pipe 513 of the water pumping module 50 communicates with the bottom of the condensation chamber 311 to inject water into the condensation chamber 311;

[0109] and / or, one end of the water outlet pipe 533 of the water pumping module 50 extends into the condensation chamber 311 for pumping out the water in the condensation chamber 311.

[0110] In this embodiment, the water inlet pipe 513 of the water pumping module 50 is connected to the bottom of the condensation chamber 311, and the condensation chamber 311 is filled with water from the bottom, avoiding noise generated when water falls on the cooling water surface when filling water from the top.

[0111] In addition, the water outlet pipe 533 of the water pumping module 50 can be inserted into the condensation chamber 311 from the upper end, and the insertion depth of the water outlet pipe 533 can be limited to ensure the lowest water level in the condensation chamber 311, avoiding the water level in the condensation chamber 311 being too low due to too fast drainage speed, which affects the condensation efficiency.

[0112] In addition, in some embodiments, when the water pumping module 50 is adopted, in order to enable the steam to quickly contact the cooling water and condense after entering the condensation chamber 311, a gas guide pipe 33 connected to the communication channel 131 is provided and the gas guide pipe 33 is inserted into the condensation chamber 311. During cooking, the water in the condensation chamber 311 submerges the air outlet end of the gas guide pipe 33, so that the steam can be directly discharged into the cooling water for condensation. At this time, when the steam is discharged into the cooling water through the gas guide pipe 33, it sprays towards the bottom of the cooling chamber, so that the water inlet pipe 513 of the water pumping module 50 communicates with the bottom of the condensation chamber 311. Thus, the cold water entering the condensation chamber 311 can collide with the steam to quickly condense the steam, and the cold water entering can also quickly reduce the water temperature of the cooling water around the air outlet end of the guide pipe, which can also improve the steam condensation efficiency. And by inserting the water outlet pipe 533 of the water pumping module 50 into the bottom of the condensation chamber 311, the water heated by the steam at the bottom of the condensation chamber 311 can also be pumped out, improving the regulation effect on the water temperature in the condensation chamber 311.

[0113] In an embodiment of the present application, the cooking appliance 100 further includes a temperature measuring structure 70, and the temperature measuring structure 70 is arranged on the appliance main body 10 for detecting the water temperature in the condensation chamber 311.

[0114] In this embodiment, the cooking appliance 100 further includes a temperature measuring structure 70 provided on the appliance main body 10. The temperature measuring structure 70 can be a thermal resistor, a thermocouple, an integrated temperature sensor, etc., and can be used to detect the water temperature in the condensation chamber 311. With such a setting, it is possible to directly determine whether the water temperature in the condensation chamber 311 exceeds the required appropriate condensation temperature range. Thus, when the appropriate condensation temperature is exceeded, the water pump module 50 is turned on to inject water and drain water for temperature adjustment into the condensation chamber 311, and when the water temperature in the condensation chamber 311 does not exceed the appropriate condensation temperature range, there is no need to turn on the water pump module 50 for temperature adjustment. Thus, there is no need to continuously turn on the water pump module 50, reducing energy consumption; and it also avoids the influence on the steam condensation effect due to the untimely turning on of the water pump module 50.

[0115] Please refer to Figure 3 , in some embodiments of the present application, the condensation module 30 further includes a gas guide pipe 33. The gas guide pipe 33 is provided in the condensation chamber 311. One end of the gas guide pipe 33 is communicated with the communication channel 131, and the other end extends to the bottom of the condensation chamber 311.

[0116] In this embodiment, the gas guide pipe 33 is provided in the condensation chamber 311. The gas guide pipe 33 forms a diversion channel 331 that penetrates through both ends for guiding the flow of steam, such that one end of the gas guide pipe 33 is communicated with the communication channel 131, and the other end extends to the bottom of the water tank 31 and is not higher than the lowest water level of the condensation chamber 311. With such a setting, when the cooking appliance 100 is in use, water not less than the lowest water level is pre-added in the condensation chamber 311, such that the air outlet end of the gas guide pipe 33 is submerged in the water. When cooking, the steam generated in the cooking space 111 can directly enter the water through the communication channel 131 and the gas guide pipe 33, such that the steam directly contacts the water and cools and condenses, improving the condensation efficiency of the steam.

[0117] Please refer to Figure 3 and Figure 4 , in some embodiments of the present application, the air outlet end of the gas guide pipe 33 has an outwardly expanding air guide port 333;

[0118] and / or, the gas guide pipe 33 further includes an extension section 335. The extension section 335 extends outward from the edge of the air outlet end of the gas guide pipe 33 and is disposed opposite to the bottom wall of the condensation chamber 311.

[0119] In this embodiment, an outwardly expanding air guide port 333 is provided at the air outlet end where the air guide pipe 33 extends to the bottom of the condensation chamber 311. The air guide port 333 is generally in the shape of a flared opening, which can increase the cross-sectional area of the channel at the air outlet end of the air guide pipe 33, enable an increase in the steam discharge area, and slow down the steam flow rate. When the cooking appliance 100 is in use, the water level in the condensation chamber 311 reaches the position of the air guide pipe 33 and at least submerges the air guide port 333, so that the steam slowly discharges from the air guide port 333, reducing the steam flow rate and extending the heat exchange time between the steam and the cooling water; and it can increase the contact area between the steam and the water, enabling the steam to fully contact the cooling water and be quickly condensed, thereby improving the condensation efficiency of the steam.

[0120] In the embodiment of the present application, it may also be that an extension section 335 extends outward from the edge of the air outlet of the air guide pipe 33. The extension section 335 is disposed opposite to the bottom wall of the condensation chamber 311, and when the cooking appliance 100 is in use, the water level in the condensation chamber 311 reaches the position of the air guide pipe 33 and at least submerges the extension section 335. With such a setting, when the steam flows out from the diversion channel 331 of the air guide pipe 33, the steam is blocked by the extension section 335 and diffuses around, preventing the steam from directly rising upward and discharging out of the water surface after being discharged from the air guide pipe 33. The setting of the extension section 335 can extend the residence time of the steam in the cooling water and the heat exchange time between the steam and the cooling water, thereby improving the condensation effect of the steam.

[0121] In some embodiments, the air guide port 333 and the extension section 335 can be provided simultaneously, with the extension section 335 extending outward from the edge of the air guide port 333, effectively improving the condensation effect of the steam in the condensation chamber 311.

[0122] In some embodiments of the present application, the cooking appliance 100 further includes a water level detection structure, which is disposed on the appliance main body 10 and is used to detect the water level in the condensation chamber 311.

[0123] In this embodiment, the cooking appliance 100 further includes a water level detection structure provided on the appliance main body 10, and the water level detection structure can detect the water level in the condensation chamber 311; to ensure that before the cooking appliance 100 starts cooking and generates steam, the water level in the condensation chamber 311 reaches at least the minimum water level requirement, so as to ensure that the steam can be quickly condensed after entering the condensation chamber 311; in addition, when the water level in the condensation chamber 311 reaches the maximum water level limit, it can also prevent the water pump module 50 from still injecting water into the condensation chamber 311, resulting in water overflow and affecting the use safety of the cooking appliance 100; and it can also prevent the water in the condensation chamber 311 from flowing into the cooking space 111 and affecting the cooking of the ingredients.

[0124] In some embodiments of the present application, the water level detection structure is at least one of a weight detection structure and an infrared photosensitive detection structure.

[0125] In this embodiment, a weight detection structure or an infrared photosensitive detection structure can be set as the water level detection structure, or a weight detection structure and an infrared photosensitive detection structure can be set at the same time. Among them, when the weight detection structure is used as the water level detection structure, the total weight of the condensation chamber 311 is detected to judge the water storage amount in the condensation chamber 311, so that the water level height in the current condensation chamber 311 can be obtained. The infrared photosensitive detection structure generally includes a transmitter and a receiver. The transmitter emits infrared rays. When the infrared rays irradiate on the liquid surface, part of the light is reflected and part of the light is refracted. When the water level is different, the refracted and reflected light is also different. For example, the light intensity and propagation direction are different. The receiver receives the reflected and refracted infrared rays, and the receiver can judge the current water level height according to the received infrared ray signal.

[0126] With reference to Figures 1 to 4 , in some embodiments of the present application, the condensation module 30 is arranged side by side with the pot body 11 and forms a condensation chamber 311; a communication channel 131 is formed in the cover body 13, and an air inlet 313 and an air outlet of the communication channel 131 are opened on one side surface of the cover body 13. The cover body 13 covers the pot body 11 and the condensation module 30, and makes the air inlet 313 communicate with the cooking space 111, and the air outlet communicate with the condensation chamber 311.

[0127] In this embodiment, by arranging the condensation module 30 side by side with the pot body 11, an air inlet 313 can be opened at the top of the condensation module 30, and a water inlet and a drain port are arranged on the water tank 31 for filling and draining the water tank 31. A communication channel 131 is formed in the cover body 13, and the cover body 13 can cover the condensation module 30 and the pot body 11 at the same time to close the condensation chamber 311 and the cooking space 111; an inlet 133 of the communication channel 131 is arranged in the area of the cover body 13 facing the pot body 11, and an outlet 135 of the communication channel 131 is arranged in the area facing the air inlet 313 of the condensation module 30. Therefore, the cooking space 111 and the condensation chamber 311 can be connected through the communication channel 131 to form a relatively closed space, so that the steam generated in the cooking space 111 can enter the condensation chamber 311 through the communication channel 131 for condensation.

[0128] Please refer to Figure 5 , the present application also proposes a control method for a cooking appliance 100, and the control method includes the following steps:

[0129] Step S10, heating the cooking space 111;

[0130] Step S20, according to the water temperature adjustment instruction, start the water pumping module 50 to inject water into the condensation chamber 311 to adjust the water temperature of the cooling water in the condensation chamber 311.

[0131] In this embodiment, the cooking appliance 100 may include the pot body 11 and the lid body 13 in the foregoing embodiment, and a steam channel is formed in the lid body 13; or it may be a side-opening structure such as a steam oven, and both the steam channel and the cooking space 111 are provided on the same structure. The structural type of the cooking appliance 100 is not limited herein. It is only necessary to provide a cooking space 111 and a condensation chamber 311 communicated with the cooking space 111 in the cooking appliance 100, and a pump water module 50 for filling and draining water in the condensation chamber 311.

[0132] When using the cooking appliance 100 and selecting a cooking mode without steam or with micro steam, the cooking mode may be cooking rice, cooking porridge, steaming, etc. First, turn on the heating structure to heat and cook the ingredients in the cooking space 111. During the heating process, steam will be generated in the cooking space 111. By providing a condensation chamber 311 communicated with the cooking space 111, the steam generated in the cooking space 111 during the cooking process can enter the condensation chamber 311 and contact the cooling water in the condensation chamber 311 to condense into water, so as to achieve the purpose of discharging micro steam or no steam during the cooking process, thereby avoiding the influence of steam on the surrounding environment and avoiding scalding users with steam. When the steam enters the condensation chamber 311 for condensation, the heat carried by it is transferred to the water in the condensation chamber 311, which will cause the water temperature of the cooling water in the condensation chamber 311 to rise. The condensation effect of the steam in the condensation chamber 311 is related to the water temperature of the cooling water. If the water temperature is too high, the condensation effect will be affected.

[0133] In the embodiment of the present application, a pump water module 50 is further provided in the cooking appliance 100. When receiving a water temperature adjustment instruction, the pump water module 50 can be started to make the condensation chamber 311 receive water, so as to adjust the water temperature in the condensation chamber 311; keep the water temperature in the condensation chamber 311 within a preset temperature range or keep the water temperature change amount per unit time within a preset range; avoid the cooling water temperature in the condensation chamber 311 being too high or the cooling water heating up too fast, so that the steam has a high condensation efficiency after entering the cooling water, so that as much steam as possible generated during the cooking process is condensed, reducing the amount of steam discharged outward, and achieving the purpose of discharging no steam or micro steam.

[0134] Among them, the generation of the water temperature adjustment instruction can be that the user inputs a control instruction according to buttons, operation screens, etc. set on the cooking appliance 100; it can also be that the user sends a control instruction to the cooking appliance 100 through a terminal. Additionally, it can also be that the control module of the cooking appliance 100 generates a water temperature adjustment instruction based on a program and preset trigger conditions. For example, it can be determined whether the water pump module 50 needs to be turned on according to the stage of the cooking program. If the main steam generation stage is the boiling stage, a water temperature adjustment instruction can be issued when it is confirmed that the boiling stage is entered. Or, it can be determined whether the water pump module 50 needs to be turned on according to the water temperature of the cooling water in the condensation chamber 311. A water temperature adjustment instruction can be issued when the water temperature of the cooling water reaches a preset temperature, or a water temperature adjustment instruction can be issued when the change amount of the water temperature of the cooling water per unit time exceeds a preset change range. Subsequently, the water pump module 50 starts to operate based on the water temperature adjustment instruction to adjust the water temperature of the cooling water in the condensation chamber 311.

[0135] The water pump module 50 may include a water injection structure 51. The water injection structure 51 may include a water pump or may be a switching device such as a solenoid valve that can control the fluid flow rate. Among them, the water injection structure 51 can be connected to an external water source, and the water pump can be turned on during the cooking process to inject cold water from the external water source into the condensation chamber 311 through the water inlet pipe. The water injection structure 51 can also be set as a switching device such as a solenoid valve that can adjust the water volume. By opening the solenoid valve, the water temperature in the condensation chamber 311 can be reduced or the water temperature in the condensation chamber 311 can be prevented from rising too fast due to the injection of steam, so that the steam has a higher condensation efficiency after entering the condensation chamber 311. The water injection speed and flow rate into the condensation chamber 311 can also be controlled by controlling the power of the water pump in the water injection structure 51 or the size of the channel opened by the solenoid valve, thereby adjusting the adjustment speed and temperature adjustment range of the water temperature in the condensation chamber 311.

[0136] In some embodiments, the water pump module 50 can be a water cooling circulation structure. The water pump module 50 includes a circulation water pump and a water cooling pipeline. Both ends of the water cooling pipeline are connected to the condensation chamber 311 to form a water circulation path. The circulation water pump provides power to discharge the water in the condensation chamber 311 into the water cooling pipeline, cool the water flowing into the water cooling pipeline, and then make the cooled water flow from the water cooling pipeline into the condensation chamber 311; thus, it can also play a role in adjusting the water temperature of the condensation chamber 311 and prevent the water temperature in the condensation chamber 311 from rising too fast due to the injection of steam, so that the steam has a higher condensation efficiency after entering the condensation chamber 311.

[0137] In this embodiment, after the water pumping module 50 is turned on, it does not necessarily completely lower the water temperature of the cooling water in the condensation chamber 311. It can also only reduce the heating rate of the cooling water in the condensation chamber 311. For example, if there is a large amount of cold water added from the external water source or the heat dissipation efficiency of the water-cooled pipe is relatively high, the water temperature in the condensation chamber 311 may be lower than the initial water temperature after the water pumping module 50 is turned on. If relatively less cold water is added or the heat dissipation efficiency in the water-cooled pipe is slow, the water temperature in the condensation chamber 311 will also rise. However, since the water pumping module 50 injects cold water into the condensation chamber 311, it can play a role in reducing the heating rate of the cooling water in the condensation chamber 311 and prevent the cooling water from heating up too fast.

[0138] It should be noted that in the embodiments of the present application, the opening and closing conditions of the water pumping module 50 can be such that the water pumping module 50 and the heating structure are turned on simultaneously after the cooking program is started and turned off after the cooking is completed. It can also be to control the opening or closing of the water pumping module 50 according to different stages of the cooking process. For example, the cooking process generally includes a heating stage, a boiling stage, a rice simmering stage or a heat preservation stage, and the main steam generation stage is during the boiling stage. At this time, the water pumping module 50 can be turned on to adjust the water temperature in the condensation chamber 311 under the condition of entering the boiling stage; the water pumping module 50 can be turned off under the condition of entering the rice simmering stage. It can also be to use a humidity sensor or other detection structures to detect whether there is steam in any one of the cooking space 111 and the condensation chamber 311 to control the opening and closing of the water pumping module 50. In addition, it can also be to determine whether to turn on or off the water pumping module 50 by detecting the change in the water temperature in the condensation chamber 311; at this time, it can be determined whether steam is generated and enters the condensation chamber 311 by judging the change in the water temperature in the condensation chamber 311. When the change in the water temperature in the condensation chamber 311 reaches the preset temperature difference condition, the water pumping module 50 is turned on to adjust the water temperature in the condensation chamber 311. When the temperature difference change in the condensation chamber 311 within the preset time period is lower than the preset temperature difference condition, it can be determined that there is no steam generation or less steam generation in the current stage, and at this time, the water pumping module 50 can be turned off.

[0139] Please refer to Figure 6 , in some embodiments of the present application, the steps of starting the water pumping module 50 to inject water into the condensation chamber 311 to adjust the water temperature of the condensation chamber 311 include:

[0140] Step S21, start the water pumping module 50 to inject water into the condensation chamber 311 and drain the condensation chamber 311.

[0141] In this embodiment, the water pumping module 50 includes a water injection structure 51 and a drainage structure 53. The structure of the water injection structure 51 refers to the foregoing embodiment. The drainage structure 53 may also include a water pump or a switching device such as a solenoid valve that can control the fluid flow rate. When receiving a water temperature adjustment instruction and turning on the water pumping module 50, the drainage structure 53 can drain the water in the condensation chamber 311 to the outside of the cooking appliance 100, which can not only drain the relatively hot water in the condensation chamber 311 to realize the replacement of the water in the condensation chamber 311 and improve the water temperature adjustment effect of the condensation chamber 311, but also avoid the water level in the condensation chamber 311 being too high and overflowing or affecting the steam entering the condensation chamber 311 due to continuously supplementing cold water from the outside and steam condensing into water, thus playing a role in adjusting the water volume in the condensation chamber 311.

[0142] Among them, the water injection structure 51 and the drainage structure 53 can be turned on simultaneously to realize the cyclic replacement of the water in the condensation chamber 311. Of course, the water injection structure 51 and the drainage structure 53 can also operate in different time periods.

[0143] In some embodiments, the water injection structure 51 and the drainage structure 53 can be set as the same structure. For example, a positive and reverse dual-cycle water pump is used as the water pumping module 50, and the positive and reverse rotations of the water pump are used to respectively realize the water injection and drainage of the condensation chamber 311 at different time periods.

[0144] In the embodiments of the present application, the water injection and drainage processes can be successively performed during the cooking process. For example, after receiving a water temperature adjustment instruction, a first preset amount of water is injected through the water injection structure 51, and a second preset amount of water is drained through the drainage structure 53 to lower the water temperature to a preset condensation temperature and then turn off the water pumping module 50. When the water temperature in the condensation chamber 311 rises again beyond the appropriate temperature range, the water injection structure 51 and the drainage structure 53 are turned on again for water injection and drainage processes.

[0145] In some embodiments, the water pumping module 50 can also be continuously turned on for water injection and drainage, so that the water in the condensation chamber 311 is continuously cyclically replaced, so that the water temperature in the condensation chamber 311 always remains at an appropriate condensation temperature, improving the condensation efficiency of the steam.

[0146] In an embodiment of the present application, in the step of starting the water pumping module 50 to inject water into the condensation chamber 311 and drain the water in the condensation chamber 311, the water injection speed is not lower than the drainage speed.

[0147] In this embodiment, when the water pump module 50 is used to inject water and drain water into the condensation chamber 311 simultaneously, if the drainage speed is faster than the water injection speed, the water level in the condensation chamber 311 will continue to drop, and ultimately the water level in the condensation chamber 311 will be lower than the minimum water level requirement, resulting in insufficient water in the condensation chamber 311 to absorb the steam heat and condense the steam. To ensure that the water injection speed is not lower than the drainage speed, the water injection speed can be the same as the drainage speed, or the water injection speed can be faster than the drainage speed, thus avoiding the decrease in the water level in the condensation chamber 311 and affecting the steam condensation effect.

[0148] Please refer to Figure 7 , in some embodiments of the present application, after the step of starting the water pump module 50 to inject water into the condensation chamber 311 and drain the water from the condensation chamber 311, the following steps are further included:

[0149] Step S30, when the water level value of the cooling water in the condensation chamber 311 reaches the first preset water level value, stop injecting water into the condensation chamber 311.

[0150] In this embodiment, when adding water to the condensation chamber 311 from an external water source to adjust the water temperature during the cooking process, it is also necessary to ensure that the water injection speed is not lower than the drainage speed or no drainage operation is performed; in addition, since steam is continuously condensed into water in the condensation chamber 311. During this process, the amount of water in the condensation chamber 311 will gradually increase. If the amount of water in the condensation chamber 311 is too much, and as steam continuously enters the condensation chamber 311, it will cause a relatively large internal pressure in the condensation chamber 311, which will affect the entry of steam into the condensation chamber 311 or cause the water in the condensation chamber 311 to overflow or flow into the cooking space 111, affecting the use safety and food cooking. In this embodiment, the highest water storage level value in the condensation chamber 311 is preset as the first preset water level value, and at least the water level in the condensation chamber 311 is continuously detected during the process of starting the water pump module 50. When the water level value of the cooling water in the condensation chamber 311 reaches the first preset water level value, stop injecting water into the condensation chamber 311 to avoid the amount of water in the condensation chamber 311 increasing beyond the preset requirements, resulting in problems such as easy water overflow.

[0151] After controlling the water pump module 50 to stop injecting water, the water pump module 50 can be stopped from draining water, or the water pump module 50 can be controlled to continue draining water from the condensation chamber 311 to reduce the amount of water in the condensation chamber 311.

[0152] Among them, the detection of the water level in the condensation chamber 311 can be achieved by setting a water level detection structure, and the water level detection structure can adopt at least one of a weight detection structure, an infrared photosensitive detection structure, or other detection structures. The water level detection structure can be turned on only when the water pump module 50 is turned on, or the water level detection structure can be continuously turned on after the cooking program is started to detect the water level in the condensation chamber 311, which is not limited here.

[0153] Please refer to Figure 8 , in some embodiments of the present application, in the step of stopping injecting water into the condensation chamber 311 when the water level of the cooling water in the condensation chamber 311 reaches a first preset water level value, it includes:

[0154] Step S31, when the water level of the cooling water in the condensation chamber 311 reaches the first preset water level, stop injecting water into the condensation chamber 311 and drain the condensation chamber 311.

[0155] In this embodiment, after the water level value of the cooling water in the condensation chamber 311 reaches the first preset water level value, control the water pump module 50 to stop injecting water into the condensation chamber 311, and control the water pump module 50 to drain the condensation chamber 311. For example, if the drainage structure 53 of the water pump module 50 is set as a water pump, then pump out the water in the condensation chamber 311; if the drainage structure 53 is a solenoid valve or other switch, then open the solenoid valve to drain the condensation chamber 311 independently. With such a setting, the amount of water in the condensation chamber 311 is appropriately reduced, which can avoid problems such as water overflow caused by the water level in the condensation chamber 311 exceeding the highest water level requirement after subsequent steam continuously enters the condensation chamber 311 and condenses into water.

[0156] It can be the drainage time after preset stop of water injection, or the preset drainage volume. When the requirements of the preset drainage time or drainage volume are reached, stop drainage. It can also stop drainage after the temperature change amount of the cooling water per unit time in the condensation chamber 311 is within a preset range; it can also control the drainage speed according to the remaining cooking time to avoid the cooling water in the condensation chamber 311 being emptied before cooking is completed. Of course, during or after drainage, if a water temperature adjustment instruction is triggered again, continue to inject water into the condensation chamber 311 to start a new round of water temperature adjustment operation.

[0157] Please refer to Figure 9 , in some embodiments of the present application, the water pump module 50 includes a circulation water pump and a water cooling pipeline. Both ends of the water cooling pipeline are communicated with the condensation chamber 311. The step of starting the water pump module 50 to inject water into the condensation chamber 311 to adjust the water temperature of the condensation chamber 311 includes:

[0158] Step S22, start the water pump module 50 to make the water in the condensation chamber 311 circulate between the condensation chamber 311 and the water cooling pipeline of the water pump module 50 to adjust the water temperature in the condensation chamber 311.

[0159] In this embodiment, the water pumping module 50 includes a circulating water pump and a water cooling pipe. Both ends of the water cooling pipe are communicated with the condensation chamber 311 to form a water circulation path. After receiving the water temperature adjustment instruction, the water pumping module 50 is started, and the circulating water pump provides power to drive the cooling water in the condensation chamber 311 to be discharged and flow into the water cooling pipe. The cooling water flowing into the water cooling pipe can be naturally cooled, or air-cooled heat dissipation, water-cooled heat dissipation, and adding heat sinks can be set to improve the cooling efficiency of the cooling water; the cooled cooling water flows from the water cooling pipe into the condensation chamber 311 and mixes with other cooling water in the condensation chamber 311; thus, it can also play a role in adjusting the water temperature of the condensation chamber 311, avoiding the water temperature in the condensation chamber 311 from being too high or rising too fast due to the injection of steam, so that the steam has a high condensation efficiency after entering the condensation chamber 311.

[0160] In addition, the power of the circulating water pump can be controlled to control the flow rate of the cooling water in the condensation chamber 311 and the water cooling pipe, so as to control the flow heat dissipation time of the cooling water in the water cooling pipe, and control the adjustment speed and temperature adjustment range of the water temperature in the condensation chamber 311.

[0161] Please refer to Figure 10 , in some embodiments of the present application, the control method of the cooking appliance 100 further includes:

[0162] Step S11, confirm the current cooking stage of the cooking appliance 100, wherein the cooking stages of the cooking appliance 100 include a heating stage, a boiling stage, and a rice simmering stage;

[0163] Adjust the working state of the water pumping module 50 according to the current cooking stage of the cooking appliance 100.

[0164] In this embodiment, it is determined whether to adjust the water temperature in the condensation chamber 311 and the water temperature adjustment range, etc. by judging the cooking stage in the current cooking process, so as to control the working state of the water pumping module 50. For example, the cooking process can be divided into multiple stages such as a heating stage, a boiling stage, a rice simmering stage, or a heat preservation stage, etc. according to the cooking time or the state in the cooking space 111. It can also be divided according to parameters such as heating power or heating power adjustment ratio. In different cooking stages, the amount of steam generated in the cooking space 111 is different. For example, the amount of steam generated is large in the boiling stage, while in the rice simmering or heat preservation stage, the amount of steam generated is relatively small. By confirming the current cooking stage of the cooking appliance 100, the amount of steam generated in the cooking space 111 at the current stage can be judged, and then the working state of the water pumping module 50 can be controlled. For example, in the cooking stage with less or no steam generated, the water pumping module 50 can be turned off; in the cooking stage with a large amount of steam generated, the water pumping module 50 can be turned on. Or, in the cooking stage with a large amount of steam generated, the water pumping module 50 can be made to inject water and drain water simultaneously, or the cooling water update speed can be increased, such as increasing the water injection speed and the water drainage speed, and when using a circulating water pump and a water cooling pipe, the water circulation speed can be increased; when the amount of steam generated is small, only water can be injected into the condensation chamber 311, or the cooling water update speed can be slowed down, such as slowing down the water injection speed and the water drainage speed, and when using a circulating water pump and a water cooling pipe, the water circulation speed can be slowed down.

[0165] In addition, the judgment method of the cooking stage can be to establish a correspondence between the cooking time and the cooking stage, that is, set corresponding time intervals for each cooking stage, judge the time interval in which the current cooking time is located, so as to judge the current cooking stage; it can also be to judge the current cooking stage according to the temperature of the cooking space 111, or to confirm the cooking stage by combining the cooking time and the temperature of the cooking space 111.

[0166] In some embodiments of the present application, the step of adjusting the working state of the water pumping module 50 according to the current cooking stage of the cooking appliance 100 includes:

[0167] Step S12, under the condition that the cooking appliance 100 is in the boiling stage, issue a water temperature adjustment instruction to start the water pumping module 50;

[0168] And / or, step S13, under the condition that the cooking appliance 100 is in the rice simmering stage, turn off the water pumping module 50.

[0169] It can be understood that when the cooking appliance 100 is in the boiling stage, a large amount of steam is generated in the cooking space 111. A large amount of steam is discharged into the condensation chamber 311 to exchange heat with the cooling water, which will accelerate the temperature rise of the cooling water. In this embodiment, under the condition of confirming that the cooking appliance 100 has entered the boiling stage, a water temperature adjustment instruction is issued to make the water pump module 50 start to work, and the water temperature of the cooling water in the condensation chamber 311 is adjusted so that the water temperature of the cooling water in the condensation chamber 311 is maintained at a state where the steam can be efficiently condensed. Among them, it can be that when the cooking appliance 100 enters the boiling stage, a water temperature adjustment instruction is issued to start the water pump module 50; it can also be that the water pump module 50 is delayed to be turned on after entering the boiling stage; or after entering the boiling stage, when it is detected that the water temperature of the cooling water in the condensation chamber 311 rises to a preset temperature or it is detected that the temperature rise rate of the cooling water reaches a preset temperature rise rate, the water pump module 50 is turned on.

[0170] In some embodiments, when the cooking appliance 100 enters the rice simmering stage or the heat preservation stage after passing through the boiling stage, at this time, the ingredients in the cooking space 111 have tended to be stable, no longer boil violently, and the amount of generated steam is relatively small. Then, the water pump module 50 can be controlled to be turned off, and there is no need to update the cooling water operation, reducing energy consumption and noise.

[0171] Please refer to Figure 11 , in some embodiments of the present application, before the step of starting the water pump module 50 according to the water temperature adjustment instruction to inject water into the condensation chamber 311 to adjust the water temperature of the cooling water in the condensation chamber 311, it further includes:

[0172] Step S14, obtaining the water temperature in the condensation chamber 311;

[0173] Step S15, under the condition that the water temperature in the condensation chamber 311 reaches the preset temperature, issuing a water temperature adjustment instruction to start the water pump module 50.

[0174] In an embodiment of the present application, a temperature measuring structure 70 is provided in the cooking appliance 100. The temperature measuring structure 70 can be a thermal resistor, a thermocouple, an integrated temperature sensor, etc., and is used to detect the water temperature of the cooling water in the condensation chamber 311. It can be understood that when steam enters the condensation chamber 311 for condensation, the heat carried by it is transferred to the water in the condensation chamber 311, which will cause the water temperature of the cooling water in the condensation chamber 311 to rise. Thus, it can be determined that steam enters the condensation chamber 311 by obtaining the water temperature of the cooling water. If the water temperature of the cooling water in the condensation chamber 311 is relatively high, it will also affect the condensation efficiency of the steam in the condensation chamber 311. In this embodiment, a preset temperature is set according to the required steam condensation efficiency. When it is detected that the water temperature of the cooling water in the condensation chamber 311 reaches the preset temperature, a water temperature adjustment instruction is issued to start the water pumping module 50, so as to prevent the water temperature of the cooling water in the condensation chamber 311 from continuing to rise or delay the water temperature rising efficiency of the subsequent cooking process, so that the steam condensation efficiency is maintained within a preset range, ensuring that as much steam as possible is condensed and ensuring the effect of no steam or micro-steam emission. In addition, as in the following embodiment, the temperature difference by which the cooling water rises compared to the initial water temperature can be detected to determine whether the preset temperature is reached.

[0175] Please refer to Figure 12 , in some embodiments of the present application, before the step of issuing a water temperature adjustment instruction to start the water pumping module 50 under the condition that the water temperature in the condensation chamber 311 reaches the preset temperature, further includes:

[0176] Step S141, obtaining the temperature difference between the current water temperature and the initial water temperature, and confirming that the water temperature in the condensation chamber 311 reaches the preset temperature under the condition that the temperature difference is not less than the first preset temperature difference.

[0177] It can be understood that in different cooking environments, such as different environmental factors like temperature, air pressure or altitude, the water temperature of the cooling water added to the condensation chamber 311 is different, and in different environments, the condensation efficiency of steam will also be affected to a certain extent. In this embodiment, during the cooking process, the current water temperature of the cooling water in the condensation chamber 311 is detected, and the temperature difference between the current water temperature and the initial water temperature of the cooling water at the start of cooking is obtained. By using this temperature difference as the judgment basis for whether the preset temperature is reached, it can more accurately reflect the impact of the steam generated during the cooking process on the cooling water, and then confirm whether it is necessary to activate the water pumping module 50. Specifically, after the cooking appliance 100 is activated, the initial water temperature in the condensation chamber 311 is first detected; then the heating structure is activated to heat the food ingredients in the cooking space 111. As the cooking process progresses, the steam generated in the cooking space 111 continuously enters the condensation chamber 311 for condensation, resulting in a change in the water temperature in the condensation chamber 311; during the cooking process, the temperature in the condensation chamber 311 is continuously or periodically detected, and the obtained current temperature is compared with the initial temperature to obtain the temperature difference of the temperature rise. If the temperature difference is less than the first preset temperature difference, it is confirmed that no steam is currently generated or the steam generation speed is slow and the steam volume is small, and it is not yet necessary to activate the water pumping module 50. If the temperature difference reaches or exceeds the first preset temperature difference range, it is confirmed that the current steam generation speed is fast, resulting in a fast heating speed of the cooling water in the condensation chamber 311, and it is necessary to activate the water pumping module 50 to update the cooling water in the condensation chamber 311 to adjust the water temperature and heating speed of the cooling water in the condensation chamber 311 to avoid affecting the steam condensation efficiency.

[0178] In some embodiments of the present application, the first preset temperature difference △T satisfies 3°C ≤ △T ≤ 30°C.

[0179] In this embodiment, in the cooking program of the cooking appliance 100, the value range of the first preset temperature difference △T for determining the activation timing of the water pumping module 50 can be 3°C ≤ △T ≤ 30°C, that is, △T can take values of 3°C, 4°C, 5°C, 6°C, 7°C, 8°C, 9°C, 10°C, 11°C, 12°C, 15°C, 20°C, 25°C, 30°C or any value between 3°C and 30°C. The value of △T can be set according to different cooking modes, cooking environments, etc. When the temperature difference between the detected current temperature and the initial temperature has reached or exceeded the set preset temperature difference, the water pumping module 50 is activated to inject water into the condensation chamber 311 to adjust the water temperature and heating speed of the cooling water in the condensation chamber 311.

[0180] Please refer to Figure 13 , in some embodiments of the present application, the control method of the cooking appliance 100 further includes:

[0181] Step S16, obtaining the water temperature change value of the cooling water in the condensation chamber 311 within a preset time;

[0182] Adjust the working state of the pump water module 50 according to the water temperature change value.

[0183] In the embodiment of the present application, during the cooking process, if the steam generation speed and the generated amount are relatively large, the heating speed of the cooling water in the condensation chamber 311 is also relatively fast. By starting the pump water module 50 to update the cooling water in the condensation chamber 311, the heating speed and the water temperature of the cooling water in the condensation chamber 311 can be slowed down and controlled. When the steam amount in the cooking process decreases, the heating speed of the cooling water in the condensation chamber 311 will also decrease accordingly. In this embodiment, the heating speed of the cooling water is judged by measuring the temperature difference in the condensation chamber 311 within a certain period of time, so as to adjust the working state of the pump water module 50.

[0184] Specifically, a second preset temperature difference can be set, the water temperature in the condensation chamber 311 is continuously or periodically detected, the temperature difference between the current water temperature in the condensation chamber 311 and the water temperature detected before the preset period is continuously or periodically judged, and it is judged whether the water temperature change value of the cooling water within the preset time does not exceed the second preset temperature difference. If the water temperature change value of the cooling water within the preset time always exceeds the second preset temperature difference, the pump water module 50 can be started, or the running state of the pump water module 50 can be maintained, or the power of the pump water module 50 can be increased when the pump water module 50 is in the running state to increase the cooling water update speed. For example, it can be adjusted from only opening the water injection structure 51 originally to injecting water and draining water at the same time; or the water injection speed and / or the drainage speed can be increased; or when a circulating water pump and a water cooling pipe are adopted, the water circulation speed can be increased, so that the water temperature or the heating speed of the cooling water can be quickly adjusted to the required range.

[0185] If the water temperature change value of the cooling water within the preset time does not exceed the second preset temperature difference, it can be determined that the cooling water no longer heats up or the heating speed of the cooling water has been slowed down to within the preset speed range, that is, it can be determined that there is no steam generation at present or the current steam generation speed and the generated amount have decreased. At this time, the pump water module 50 can be closed, or the cooling water update speed can be slowed down. For example, it can be adjusted from injecting water and draining water at the same time originally to only injecting water, or the water injection speed and the drainage speed can be slowed down; or when a circulating water pump and a water cooling pipe are adopted, the water circulation speed can be slowed down, so as to avoid the pump water module 50 continuously keeping the high power on, and reduce the noise and energy consumption.

[0186] In some embodiments of the present application, the step of adjusting the working state of the pump water module 50 according to the water temperature change value includes:

[0187] Step S17, under the condition that the water temperature change value exceeds the second preset temperature difference, issue a water temperature adjustment instruction to start the pump water module 50;

[0188] Step S18, turn off the water pumping module 50 under the condition that the water temperature change value does not exceed the second preset temperature difference.

[0189] In this embodiment, by setting the second preset temperature difference, it is determined whether the water temperature change value of the cooling water reaches the second preset temperature difference within a preset time to judge the heating rate of the cooling water. If the water temperature of the cooling water changes to exceed the second preset temperature difference within the preset time, it is confirmed that the heating rate of the water temperature of the cooling water is relatively fast, and it can be judged that the steam generation rate and generation amount in the cooking space 111 during the cooking process are relatively large. At this time, a water temperature adjustment instruction needs to be issued to make the water pumping module 50 start to work to adjust the water temperature of the cooling water in the condensation chamber 311, so as to prevent the cooling water from continuously rising rapidly to a temperature range that is not conducive to steam condensation, so that the water temperature of the cooling water in the condensation chamber 311 is maintained in a state that can efficiently condense steam.

[0190] If the water temperature change value of the cooling water does not exceed the second preset temperature difference within the preset time, it is judged that the current heating rate of the water temperature of the cooling water is relatively slow, and the water pumping module 50 can be turned off, thereby reducing the energy consumption and noise during the cooking process.

[0191] The value range of the second preset temperature difference can be 3°C to 30°C, that is, the second preset temperature difference can take values of 3°C, 4°C, 5°C, 6°C, 7°C, 8°C, 9°C, 10°C, 11°C, 12°C, 15°C, 20°C, 25°C, 30°C or any value between 3°C and 30°C. The value of the second preset temperature difference can be set according to different cooking modes, cooking environments, etc.

[0192] Please refer to Figure 14 , in some embodiments of the present application, after the step of starting the water pumping module 50 to inject water into the condensation chamber 311 to adjust the water temperature of the condensation chamber 311, it further includes:

[0193] Step S40, obtain the current cooking time, and turn off the water pumping module 50 under the condition that the cooking time is not less than the preset cooking time.

[0194] Please refer to Figure 15 , in some embodiments of the present application, after the step of starting the water pumping module 50 to make water enter the condensation chamber 311 to adjust the water temperature of the condensation chamber 311, it further includes:

[0195] Step S50, obtain the remaining cooking time, and turn off the water pumping module 50 under the condition that the remaining cooking time does not exceed the preset remaining time.

[0196] In the final stage of cooking, such as the warming stage or the final simmering stage of cooking rice, within this stage, the generation rate and amount of steam are relatively small, and it is possible to achieve a relatively high condensation efficiency when the steam enters the condensation chamber 311 without starting the water pump module 50. In this embodiment, after starting the water pump module 50 to adjust the water temperature in the condensation chamber 311, it is determined whether to turn off the water pump module 50 by judging whether the current cooking program has reached the cooking stage where the water pump module 50 does not need to be turned on. At this time, it can be determined that the current cooking program has reached the cooking stage where the water pump module 50 does not need to be turned on when it is judged that the current cooking time reaches the preset cooking time; it can also be judged by the remaining cooking time. When the remaining cooking time does not exceed the preset remaining time, it can also be determined that the current cooking program has reached the cooking stage where the water pump module 50 does not need to be turned on. At this time, the water pump module 50 can be turned off to avoid the water pump module 50 being continuously turned on until the cooking program ends, thereby reducing energy consumption.

[0197] Please refer to Figure 16 , in some embodiments of the present application, before the step of heating the cooking space 111, it further includes:

[0198] Step S01, detecting the water level value of the cooling water in the condensation chamber 311;

[0199] Step S02, under the condition that the water level value of the cooling water in the condensation chamber 311 is lower than the second preset water level value, injecting water into the condensation chamber 311 until the water level value of the cooling water in the condensation chamber 311 reaches the second preset water level value;

[0200] Step S03, under the condition that the water level value of the cooling water in the condensation chamber 311 reaches the second preset water level value, executing the step of heating the cooking space 111.

[0201] In the embodiment of the present application, a condensation chamber 311 is provided in the cooking appliance 100 to condense the steam generated during the cooking process into water; among them, it is necessary to pre-fill a part of water in the condensation chamber 311 so that the steam condenses when it enters the condensation chamber 311. If the amount of water stored in the condensation chamber 311 is small, the heat carried by the steam will cause the water temperature in the condensation chamber 311 to rise rapidly, and there is not enough water to absorb the heat of the steam to condense the steam, which will also affect the condensation efficiency of the steam. In this embodiment, after enabling the cooking mode of the cooking appliance 100, first judge whether the water level value of the cooling water in the condensation chamber 311 reaches the second preset water level value. The second preset water level value can be the minimum water level requirement of the condensation chamber 311 or the water level requirement determined according to the current cooking mode and the weight of the ingredients, etc., to make the steam have a relatively high condensation efficiency. When the amount of water stored in the condensation chamber 311 reaches or exceeds the second preset water level value, it is confirmed that there is sufficient water in the condensation chamber 311 to absorb the heat of the steam to condense the steam, and then the heating structure can be continued to be turned on to heat the cooking space 111 to cook the ingredients.

[0202] When the water level of the cooling water in the condensation chamber 311 does not reach the second preset water level value, water is injected into the condensation chamber 311 until the water level reaches the second preset water level; it can be to make the cooking appliance 100 alarm to remind the user to inject water; it can also be to separately set an injection module or use the water pump module 50 to automatically inject water into the condensation chamber 311.

[0203] In the embodiments of the present application, a weight detection structure or an infrared photosensitive detection structure can be set as the water level detection structure, or a weight detection structure and an infrared photosensitive detection structure can be set at the same time to detect the water level in the condensation chamber 311. Among them, when the weight detection structure is used as the water level detection structure, the water storage amount in the condensation chamber 311 is judged by detecting the total weight of the condensation chamber 311, so that the water level height in the current condensation chamber 311 can be obtained. The infrared photosensitive detection structure generally includes a transmitter and a receiver. The transmitter emits infrared rays. When the infrared rays irradiate on the liquid surface, part of the light is reflected and part of the light is refracted. When the water level is different, the refracted and reflected light is also different, for example, the light intensity and propagation direction are different; and the receiver receives the reflected and refracted infrared rays, and the receiver can judge the current water level height according to the received infrared ray signal.

[0204] Refer to Figure 17, in an embodiment of the present application, when the cooking appliance 100 starts to operate, first detect whether the water level value of the cooling water in the condensation chamber 311 reaches the second preset water level value. The second preset water level value can be the minimum water level requirement of the condensation chamber 311 or the water level requirement that enables the steam to have a higher condensation efficiency determined according to the current cooking mode and the weight of the ingredients, etc. If the water level of the cooling water in the condensation chamber 311 does not reach the usage requirement, a water addition instruction is issued, for example, the user is notified to add water by means of an indicator light, a buzzer or sending a message to the user terminal. When the water injection structure 51 is provided, it can also be to control the water injection structure 51 to add water until the second preset water level. After confirming that the water level value of the cooling water in the condensation chamber 311 reaches the second preset water level value, the heating module is turned on to heat the cooking space 111; after confirming that the cooking appliance 100 enters the boiling stage, a water temperature adjustment instruction can be directly issued to make the water pumping module 50 operate, or as in the illustrated embodiment, when it is confirmed that the water temperature in the condensation chamber 311 reaches the preset temperature or the temperature change value within the preset time period reaches the second preset temperature difference, a water temperature adjustment instruction is issued to make the water pumping module 50 operate; at this time, the water pumping module 50 can control the water pumping module 50 to only inject water, or inject water and drain water simultaneously, and when a circulating water pump is used, control the cooling water to circulate in the condensation chamber 311 and the water cooling pipeline; the power of the water pumping module 50 can also be controlled to control the cooling water update speed. In addition, the water pumping module 50 can be turned off after the simmering stage or the heat preservation stage after the cooking appliance 100 enters the boiling stage, or after reaching the preset cooking time, or when there is a preset remaining time in the cooking program, or under the condition that the temperature change value within the preset time period does not exceed the second preset temperature difference.

[0206] Through the description of the above embodiments, those skilled in the art can clearly understand that the above embodiment methods can be implemented by means of software plus a necessary general hardware platform.
