Description

Technical Field

The high-temperature and high-humidity steam will cause the temperature and humidity in the narrow kitchen environment, making the kitchen humid, which easily affects the service life of kitchen cabinets and kitchen appliances, etc., and there is also a safety risk of scalding users. In related technologies, a condensation chamber can be set so that the steam is discharged into the condensation chamber and contacts the cooling water to condense into water, thereby reducing or avoiding the outward discharge of steam.

[0064] This application proposes a control method for a cooking appliance 100, which can be implemented through the cooking appliance 100. With reference to Figures 1 to 4 , a cooking space 115 and a condensation chamber 117 that are connected and communicate with each other are formed in the cooking appliance 100, and the cooking appliance 100 is provided with a detection module 30 for detecting the cooling water information of the condensation chamber 117.

[0065] Please refer to Figure 5 , the control method includes the following steps:

[0066] Step S10, obtaining the cooling water information of the condensation chamber 117 before the boiling stage, and the cooling water information includes at least one of the water quantity information and the water temperature information of the cooling water;

[0067] Step S20, when the cooling water information before the boiling stage meets the preset cooling requirements, set the heating power of the cooking appliance 100 at the boiling stage to the first preset power;

[0068] Step S30, when the cooling water information before the boiling stage does not meet the preset cooling requirements, set the heating power of the cooking appliance 100 at the boiling stage to the second preset power, and the second preset power is less than the first preset power.

[0069] In this embodiment, a detection module 30 can be set in the cooking appliance 100 to detect the cooling water information in the condensation chamber 117. The detection module 30 can be at least one of a water level detection module, a weight detection module, and a temperature detection module. The corresponding detected cooling water information can include at least one of the water volume information and the water temperature information of the cooling water. Among them, the water volume information of the cooling water can also be reflected by any one or two of the water level information and the weight information of the cooling water. For example, an infrared photosensitive sensor or a capacitive sensor can be set to detect the water level of the cooling water; the weight of the cooling water can be detected by setting a weight sensor. For example, the total weight of the water tank 113 forming the condensation chamber 117 is detected to convert the weight of the cooling water; in some embodiments, it can also be to obtain the weight by detecting the water level, or to obtain the water level information by detecting the weight.

[0070] In the embodiments of the present application, only one of the parameters of the cooling water can be limited, and only confirm whether this parameter meets the preset requirements to correspondingly adjust the heating power during the cooking process. For example, it can be only confirmed whether the water volume information of the cooling water is within the preset water volume range, or only confirmed whether the water temperature information of the cooling water is higher than the preset temperature value. Of course, it is also possible to limit two or more parameter information of the cooling water. For example, it is necessary to confirm whether the water volume of the cooling water is within the preset water volume range and also confirm whether the water temperature of the cooling water is under the preset temperature condition; in some embodiments, for example, in the cooking appliance 100 provided with a water circulation system, it is also possible to confirm whether the cooling water is in a circulating flow state, etc.

[0071] Among them, in the embodiment of the present application, before entering the boiling stage, if it is confirmed that the cooling water in the condensation chamber 117 meets the conditions of the preset cooling requirements, the control program will control the cooking appliance 100 to cook normally at the first preset power in the boiling stage according to the normal cooking program. If it is confirmed that the cooling water in the condensation chamber 117 does not meet the conditions of the preset cooling requirements, for example, the water temperature of the cooling water exceeds the preset water temperature; the water volume of the cooling water is lower than the minimum preset water volume or exceeds the preset maximum water volume; at this time, the cooking appliance 100 can be made to cook at a second preset power lower than the first preset power after entering the boiling stage; that is, by reducing the heating power in the boiling stage, the boiling degree in the boiling stage is reduced, and a low-power simmering cooking mode is entered until the cooking ends. With such a setting, the amount of steam generated in the boiling stage can be reduced, thereby avoiding a large amount of steam entering the condensation chamber 117 when the water volume of the cooling water is small or the water temperature is high, resulting in incomplete condensation of the steam and some steam being discharged outward, making it difficult to achieve the purpose of no steam or micro-steam emission. In addition, it can avoid the problem of water overflow in the condensation chamber 117 caused by a large amount of steam entering the condensation chamber 117 and condensing into water when the water volume of the cooling water exceeds the highest water level line.

[0072] It should be noted that in the embodiment of the present application, using the second preset power for cooking only means that the heating power needs to be reduced when the cooling water does not meet the preset cooling requirements. In the embodiment of the present application, the situations where the cooling water does not meet the preset cooling requirements include the water temperature being higher than the preset water temperature, the water volume being lower than the preset minimum water volume or higher than the preset maximum water volume, and the situations where both the water temperature and the water volume do not meet the requirements; based on different situations where the preset cooling requirements are not met, different second preset powers can be set; and in the same situation where the preset cooling requirements are not met, for example, in the abnormal situation where the water temperature is higher than the preset water temperature, different second preset powers can also be set based on different actual water temperatures; similarly, in the situation where the water volume is lower than the preset minimum water volume, different second preset powers can also be set for cooking according to the actual water volume.

[0073] Therefore, it can be understood that in the technical solution of the present application, a detection module 30 is provided in the cooking appliance 100, so that the cooling water information in the condensation chamber 117 can be directly detected, such as the water volume and water temperature of the cooling water. Thus, when it is detected that the cooling water does not meet the cooling requirements, the user or the control system can take corresponding actions, such as prompting the user to add water, reduce water or change water in the condensation chamber 117, or the control system drives the water pumping structure 50 to automatically add water, reduce water or change water; in addition, when it is confirmed that the cooling water in the condensation chamber 117 cannot be adjusted temporarily, the boiling degree can be reduced by reducing the heating power, and the steam generation can be reduced. For example, in the normal state, the cooking appliance 100 heats and cooks at a first preset power in the boiling stage. When the cooling water does not meet the preset cooling requirements, it heats and cooks at a second preset power lower than the first preset power in the boiling stage, so as to reduce the steam generation amount, and thus reduce the steam amount entering the condensation chamber 117; with such a setting, it is possible to avoid the problem of water overflow in the condensation chamber 117 due to a large amount of steam condensing into water when the cooling water level is too high, and improve the safety of the cooking process; it is also possible to avoid the problem of a large amount of steam being discharged when part of the steam cannot be condensed in time when the cooling water level is too low or the water temperature is too high, and improve the reliability of realizing steam-free or micro-steam emission during the cooking process. At this time, there is no need to directly interrupt the cooking program, which may affect normal cooking.

[0074] Please refer to Figure 6 , in some embodiments of the present application, when the cooling water information is the water temperature information of the cooling water, the step of obtaining the cooling water information in the condensation chamber 117 includes:

[0075] Step S11, obtaining the water temperature information of the cooling water in the condensation chamber 117 before the boiling stage.

[0076] Based on this, under the condition that the cooling water information before the boiling stage meets the preset cooling requirements, the step of setting the heating power of the cooking appliance 100 in the boiling stage to the first preset power includes:

[0077] Step S21, if it is confirmed that the cooling water information meets the preset cooling requirements under the condition that the water temperature of the cooling water is lower than the preset water temperature value, then set the heating power of the cooking appliance 100 in the boiling stage to the first preset power.

[0078] Similarly, under the condition that the cooling water does not meet the preset cooling requirements, the step of heating and cooking at the second preset power includes:

[0079] Step S31, if the cooling water information does not meet the preset cooling requirements under the condition that the water temperature of the cooling water is higher than the preset temperature, then set the heating power of the cooking appliance 100 in the boiling stage to the second preset power.

[0080] In this embodiment, the method of detecting the temperature of the cooling water is adopted to confirm whether the cooling water meets the usage conditions. When the water temperature of the cooling water is higher than the preset water temperature value, the temperature that can be transferred to the cooling water when the steam contacts the cooling water is limited, resulting in a relatively low condensation efficiency of the steam. At this time, the cooking appliance 100 can be controlled to heat and cook at a second preset power during the boiling stage, so as to reduce the boiling degree, make the food materials tend to be stable, enable the food materials to absorb more water, and reduce the generation amount of steam; thereby, the steam entering the condensation chamber 117 for condensation can be reduced, so that the cooling water under the current temperature state can also fully condense the steam, achieving the purpose of no steam or micro-steam emission.

[0081] Under the condition that the water temperature of the cooling water is lower than the preset water temperature value, at this time the temperature of the cooling water is relatively low, which can enable the steam to condense quickly; thus, the cooking appliance 100 can be heated and cooked in the cooking space 115 at a conventional first preset power during the boiling stage, maintaining a relatively high cooking efficiency and without the problem of excessive steam discharging outwards, and the purpose of no steam or micro-steam emission can be achieved.

[0082] Among them, the preset temperature value in the cooking system can be 30°C to 60°C, and can be 30°C, 35°C, 40°C, 45°C, 50°C, 55°C, 60°C, and any value between 30°C and 60°C. Of course, it can also be appropriately adjusted according to requirements, such as setting a preset temperature slightly higher than 60°C. The preset temperature for the cooling water to meet the cooling requirements can be set in the control program of the cooking appliance 100 when manufacturing the cooking appliance 100, or can be set by the user himself. For different cooking programs, different preset temperatures can be set. For example, in the program settings corresponding to cooking methods such as cooking rice, cooking porridge, and cooking soup, the preset water temperature value of the cooling water to meet the cooling requirements can be different.

[0083] Please refer to Figure 7 , in some embodiments of the present application, the cooling water information includes water temperature information and water volume information, and the steps of obtaining the cooling water information in the condensation chamber 117 include:

[0084] Step S11, obtaining the water volume information of the cooling water in the condensation chamber before the boiling stage;

[0085] When the water volume information is within the preset water volume range, obtaining the water temperature information of the cooling water in the condensation chamber before the boiling stage.

[0086] In this embodiment, before confirming whether the water temperature of the cooling water meets the water temperature range of the preset cooling requirement, it is necessary to first confirm whether the water volume of the cooling water in the condensation chamber 117 is within the preset water volume range. If the water volume of the cooling water is too low, even if the water temperature of the cooling water meets the requirements, after a large amount of steam enters the condensation chamber 117, it is easy to cause the water temperature of the cooling water to rise rapidly and reduce the condensation efficiency; if the water volume of the cooling water exceeds the preset maximum water volume, after a large amount of steam enters the condensation chamber 117 and condenses, it is easy to cause the condensation chamber 117 to overflow with water.

[0087] Determine in advance whether the water volume of the cooling water in the condensation chamber 117 meets the preset water volume requirement, so as to adjust the water volume in time when the water volume does not meet the preset water volume requirement, and the water temperature may also change during the adjustment process, avoiding repeated confirmation of the water temperature. If the water volume in the condensation chamber 117 does not meet the preset water volume requirement and the water volume cannot be adjusted temporarily, the cooking program can be terminated to issue an alarm or continue cooking by reducing the heating power. Confirming both the water volume of the cooling water and the water temperature of the condensed water can further improve the reliability of realizing steam-free or micro-steam emission during the cooking process, and improve the use safety of the cooking appliance 100.

[0088] For the detection of the water volume of the cooling water in the condensation chamber 117, the water surface position can be directly detected by setting a detection structure such as an infrared photosensitive sensor to judge the water level of the cooling water. It is also possible to detect the total weight of the water tank 113 forming the condensation chamber 117 and the cooling water by setting a detection structure such as a weight sensor; both can confirm the water volume in the condensation chamber 117.

[0089] In an embodiment of the present application, the control method of the cooking appliance 100 further includes:

[0090] Under the condition that the water volume information of the cooling water before the boiling stage is not within the preset water volume range, set the heating power of the boiling stage of the cooking appliance 100 to the second preset power.

[0091] In this embodiment, when the water volume of the cooling water is lower than the preset minimum water volume or higher than the preset maximum water volume, heating and cooking can be performed at the second preset power lower than the first preset power during the boiling stage. That is, the boiling degree is weakened, so that more water is absorbed by the food materials, thereby reducing the amount of steam generated; it is also possible to slow down and reduce the amount of steam entering the condensation chamber 117 per unit time. With such a setting, when the water volume in the condensation chamber 117 is lower than the preset minimum water volume, the heating rate of the cooling water can also be slowed down, avoiding the cooling water from quickly rising to a temperature range that is not conducive to condensation. When the water volume in the condensation chamber 117 is higher than the preset maximum water volume, it is possible to avoid the generation of more steam causing the water volume in the condensation chamber 117 to increase to an overflow state. And the cooking appliance 100 can maintain the operating state without closing the cooking program for water replenishment or water reduction operations, reducing the impact on the cooking operation of the cooking appliance 100.

[0092] It can be understood that during the cooking process, the main steam generation stage is in the boiling stage. When it is detected that the water volume in the condensation chamber 117 is not within the preset water volume range, an instruction to adjust the water volume in the condensation chamber 117 can be issued first. If, after issuing the instruction to adjust the water volume in the condensation chamber 117, it is confirmed that the water volume in the condensation chamber 117 cannot be adjusted by other means temporarily, in order not to affect the cooking operation, the heating structure can be turned on for heating. Before entering the boiling stage, no steam is generated in the cooking space 115 or the amount of steam generated is small and the steam generation process is slow; during this process, the heating structure can work at the heating power of the normal cooking program to maintain a high heating and temperature rising efficiency; when the cooking program enters the boiling stage, the generation of steam in the boiling stage can be reduced by operating the heating structure at the second preset power, so that the cooking appliance 100 can continue cooking, and the purpose of no steam or micro-steam emission can be achieved, and problems such as water overflow will not occur.

[0093] It should be noted that in the embodiments of the present application, it can be determined whether the current stage is in the boiling stage by detecting whether there is a large amount of steam generated in the cooking space 115; it can also be determined whether the current stage is in the boiling stage by confirming the cooking time; it can also be determined whether the current stage enters the boiling stage by detecting any factor such as the temperature and pressure in the cooking space 115 and the temperature and water volume of the condensation chamber 117.

[0094] Of course, it is not difficult to understand that when it is detected that the water volume in the condensation chamber 117 is not within the preset water volume range, the water volume can be adjusted by adding or reducing water to the condensation chamber 117, which can be an operation by the user or the pump water structure 50 can be set to automatically add and drain water.

[0095] Please refer to Figure 8 , in some embodiments of the present application, in the step of setting the heating power of the cooking appliance 100 in the boiling stage to the second preset power under the condition that the cooling water information before the boiling stage does not meet the preset cooling requirements, it includes:

[0096] Step S311, under the condition that the water temperature information of the cooling water before the boiling stage is higher than the preset water temperature value, confirm that the cooling water information does not meet the preset cooling requirements and issue a water change instruction;

[0097] Step S312, after issuing the water change instruction and after a preset time, if the water temperature information of the cooling water is higher than the preset water temperature value, set the heating power of the cooking appliance 100 in the boiling stage to the second preset power.

[0098] In this embodiment, when it is confirmed that the temperature of the cooling water is higher than the preset temperature, a water replacement instruction can be sent first. The water replacement instruction can be an indication signal, such as a buzzer, an indicator light, or a message sent to the terminal, etc., to notify the user to add water, reduce water, or replace the water in the condensation chamber 117, so that the water temperature of the cooling water in the condensation chamber 117 meets the usage requirements. The water replacement instruction can also be a control instruction, which can directly control the water pumping structure 50 to automatically add water, drain water, etc. to the condensation chamber 117. If the cooling water in the condensation chamber 117 has been made to be at an appropriate water temperature by replacing the water in the condensation chamber 117, there is no need to heat and cook at the second preset power during the boiling stage, and cooking can be carried out with a high heating efficiency, and the purpose of no steam or micro-steam emission can be achieved.

[0099] After a preset time after the water replacement instruction is sent, if the detected water temperature information of the cooling water is still higher than the preset water temperature value, it can be confirmed that the user is currently temporarily unable to perform water replacement treatment on the condensation chamber 117, or it can be confirmed that the water pumping structure 50 fails or cannot replace the water in the condensation chamber 117 due to other factors. Under this condition, the heating power in the boiling stage is set to the second preset power, and the cooking appliance 100 is heated and cooked at the second preset power in the boiling stage, so as to reduce the boiling degree in the boiling stage, reduce the steam generated in the boiling stage, so that the cooling water can fully condense the steam entering the condensation chamber 117 under the current water temperature condition of the condensation chamber 117, and ensure the effect of no steam or micro-steam emission.

[0100] Please refer to Figure 9 , in some embodiments of the present application, the step of setting the heating power of the cooking appliance 100 in the boiling stage to the second preset power after the water replacement instruction is sent and after a preset time, if the water temperature information of the cooling water is higher than the preset water temperature value, includes:

[0101] After the water replacement instruction is sent and after a preset time, if the water temperature information of the cooling water is higher than the preset water temperature value, the heating power before the boiling stage of the cooking appliance 100 is set to the first preset power, and the heating power in the boiling stage of the cooking appliance 100 is set to the second preset power.

[0102] It can be understood that during the cooking process, the main steam generation stage is the boiling stage of the liquid in the cooking space 115. If, after issuing an instruction to change the water in the condensation chamber 117, it is confirmed that the water temperature of the cooling water in the condensation chamber 117 cannot be adjusted by changing the water temporarily, in order not to affect the cooking operation, the heating structure can be turned on for heating. Before entering the boiling stage, no steam is generated or the amount of steam generated is small and the steam generation process is slow in the cooking space 115. During this process, the heating power of the cooking appliance 100 can be set to a first preset power, so that the heating structure works at the first preset power set conventionally to maintain a high heating and temperature rising efficiency. In addition, the heating power of the cooking appliance 100 in the boiling stage is set to a second preset power, so that after the cooking appliance 100 enters the boiling stage, it is heated at the second preset power to reduce the steam generated in the boiling stage, so that the cooling water can fully condense the steam entering the condensation chamber 117 under the current water temperature condition of the condensation chamber 117, achieving the purpose of steam-free or micro-steam emission.

[0103] It should be noted that in some embodiments, the conventional heating powers set in the heating stage, the boiling stage, and the heat preservation stage can be made different. At this time, the cooking in the embodiments of the present application at the first preset power or the second preset power is heating and cooking at the first preset power or the second preset power set in each stage. The limitation that the second preset power is less than the first preset power means that the second preset power is less than the first preset power set in the same stage. For example, assume that the first preset power in the heating stage is 100; the first preset power in the boiling stage is 70, and the second preset power in the boiling stage is 40. At this time, the cooking appliance 100 will be heated at a heating power of 100 in the heating stage before the boiling stage. If the cooling water meets the preset cooling requirements, the cooking appliance 100 will be heated at a heating power of 70 in the boiling stage; if the cooling water does not meet the cooling requirements and the cooling water cannot be adjusted temporarily, the cooking program will be heated at a heating power of 40 in the boiling stage.

[0104] In some embodiments of the present application, before the step of setting the heating power of the cooking appliance 100 in the boiling stage to the second preset power, it further includes:

[0105] Under the condition that the temperature of the cooking space 115 reaches the preset temperature, it is confirmed that the boiling stage is entered.

[0106] In this embodiment, the temperature in the cooking space 115 is detected to confirm whether the boiling stage has been entered. The temperature sensor 70 can be set outside the pot body 111 that forms the cooking space 115 in the cooking appliance 100, or can be set on the upper cover assembly 13 and at the opening position of the cooking space 115, or can also be set directly in the cooking space 115 to detect the temperature of the ingredients. Additionally, the temperature can be detected at regular intervals or in real time.

[0107] It can be understood that when the liquid in the ingredients boils, the boiling temperature under standard atmospheric pressure is approximately 100°C. However, if the temperature sensor 70 is located outside the pot body 111 that forms the cooking space 115 or is set on the lid, due to the distance and the gap of the structure of the pot body 111 itself, the temperature at the position where the temperature sensor 70 is located may be lower than 100°C. Therefore, the set preset temperature value needs to be set according to the position where the temperature sensor 70 is set, and can also be combined with environmental factors such as the environment in which the cooking appliance 100 is applied.

[0108] When the detected temperature value reaches the preset temperature, such as being consistent with the preset temperature, exceeding the preset temperature, or being lower than the preset temperature by a certain difference; it can be confirmed that the current boiling stage has been entered, and thus the step of heating and cooking at the second preset power can be executed.

[0109] In an embodiment of the present application, under the condition that the temperature in the cooking space 115 reaches the preset temperature, the step of confirming the entry into the boiling stage includes:

[0110] Under the condition that the temperature in the cooking space 115 is not lower than 95°C, it is confirmed that the boiling stage has been entered.

[0111] In this embodiment, when the temperature sensor 70 detects that the temperature in the cooking space 115 is not lower than 95°C, it is confirmed that the boiling stage has been entered, and then heating and cooking can be performed at the second preset power to reduce the generation of steam.

[0112] Please refer to Figure 10 , in some embodiments of the present application, after the step of setting the heating power of the cooking appliance 100 in the boiling stage to the first preset power under the condition that the cooling water information before the boiling stage meets the preset cooling requirements, the following steps are further included:

[0113] Step S22, after entering the boiling stage, obtain the water temperature information of the cooling water in the condensation chamber;

[0114] Step S23, when the water temperature information of the cooling water in the boiling stage is higher than the preset water temperature value, adjust the heating power of the cooking appliance 100 to the second preset power.

[0115] It can be understood that during the process of steam entering the condensation chamber 117 for condensation, which is also a heat transfer process, the water temperature of the cooling water will increase. In this embodiment, if it is confirmed that the cooling water meets the preset cooling requirements before the boiling stage, the heating structure is started to heat and cook, and the initial heating power when entering the boiling stage is set to the first preset power; so that the cooking appliance 100 always heats the cooking space 115 at the first preset power for a period of time when entering the boiling stage; and during the boiling stage, the water temperature of the cooling water is detected in real time or at regular intervals. If it is detected during the boiling stage that the water temperature of the cooling water rises to a temperature higher than the preset temperature, the heating power of the cooking appliance 100 is adjusted to the second preset power to reduce the boiling degree in the cooking space 115, make the ingredients tend to be stable, enable the ingredients to absorb more water, and reduce the generation amount of steam; thereby reducing the steam entering the condensation chamber 117 for condensation, avoiding the continuous and rapid rise of the temperature of the cooling water, and enabling the cooling water at the current temperature state to also fully condense the steam, achieving the purpose of no steam or micro-steam emission.

[0116] Please refer to Figure 11 , in some embodiments of the present application, in the step of adjusting the heating power of the cooking appliance 100 to the second preset power when the water temperature information of the cooling water in the boiling stage is higher than the preset water temperature value, it includes:

[0117] Step S231, when the water temperature information of the cooling water in the boiling stage is higher than the preset water temperature value, issue a water change instruction;

[0118] Step S232, after issuing the water change instruction and after a preset time, if the water temperature information of the cooling water is higher than the preset water temperature value, adjust the heating power of the cooking appliance 100 to the second preset power.

[0119] In this embodiment, as the boiling stage continues, steam continuously enters the condensation chamber 117 to contact the cooling water. When it is confirmed that the temperature of the cooling water is heated by the steam to be higher than the preset water temperature value, a water change instruction can be issued first. The water change instruction can be an indication signal, such as a buzzer, an indicator light, or information sent to the terminal, etc., to notify the user to add water, reduce water, or change the water in the condensation chamber 117, so that the water temperature of the cooling water in the condensation chamber 117 meets the usage requirements. The water change instruction can also be a control instruction, which can directly control the water pumping structure 50 to automatically add water, drain water, etc. to the condensation chamber 117. If the cooling water in the condensation chamber 117 has been made to be at a suitable water temperature by changing the water in the condensation chamber 117, there is no need to adjust the heating power of the cooking appliance 100 to the second preset power, and cooking can be carried out with a high heating efficiency, and the purpose of no steam or micro-steam emission can be achieved.

[0120] After a preset time from issuing the water change instruction, if the detected water temperature information of the cooling water is still higher than the preset water temperature value, it can be confirmed that the user is currently temporarily unable to perform water change treatment on the condensation chamber 117, or it can be confirmed that the water pumping structure 50 fails or cannot change water for the condensation chamber 117 due to other factors. Under this condition, the heating power of the cooking appliance 100 is adjusted to a second preset power to reduce the boiling degree during the boiling stage, so that the steam generated during the boiling stage is reduced, so that the cooling water can fully condense the steam entering the condensation chamber 117 under the current water temperature condition of the condensation chamber 117, ensuring the effect of no steam or micro-steam emission.

[0121] Please refer to Figure 12 , in some embodiments of the present application, the step of issuing the water change instruction includes:

[0122] Send an instruction to drain the condensation chamber 117 and inject water into the condensation chamber 117 after draining.

[0123] In this embodiment, a water pumping structure 50 is further provided in the cooking appliance 100. The water pumping structure 50 can be used to change water for the condensation chamber 117 after receiving the water change instruction; the water pumping structure 50 can include a water injection structure 51 and a drainage structure 53. The water injection structure 51 is communicated with an external water source, and the cold water of the external water source can be injected into the condensation chamber 117 by using the water injection structure 51 to reduce the water temperature in the condensation chamber 117 or prevent the water temperature in the condensation chamber 117 from rising too fast due to the injection of steam, so that the steam has a high condensation efficiency after entering the condensation chamber 117. The drainage structure 53 can drain the water in the condensation chamber 117 to the outside of the cooking appliance 100, which can not only drain the water with a higher temperature in the condensation chamber 117 to realize the replacement of the water in the condensation chamber 117 and improve the water temperature adjustment effect on the condensation chamber 117; but also prevent the water level in the condensation chamber 117 from overflowing or affecting the entry of steam into the condensation chamber 117 due to continuous replenishment of external cold water and condensation of steam into water, playing a role in adjusting the water volume in the condensation chamber 117. 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 structure 50, and the positive and reverse rotation of the water pump is used to realize the water injection and drainage of the condensation chamber 117 at different times respectively.

[0124] In this embodiment, when it is confirmed that the cooling water in the condensation chamber 117 does not meet the preset cooling requirements before or during the boiling stage, a water change instruction can be issued. The water change instruction is an instruction to drain the condensation chamber 117 and inject water into the condensation chamber 117 after drainage. Making the water pumping structure 50 change the water in the condensation chamber 117 can be to continuously turn on the water injection structure 51 and the drainage structure 53 to achieve the purpose of continuous cyclic water change; it can also be to make the water pumping structure 50 turn on for a period of time to drain the cooling water with a relatively high temperature in the condensation chamber 117 and inject water with a relatively low temperature into the condensation chamber 117. 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 117; of course, the water injection structure 51 and the drainage structure 53 can also be operated in different time periods. For example, the drainage structure 53 is first turned on to drain the high-temperature cooling water in the condensation chamber 117, and then the water injection structure 51 is turned on to inject the cooling water with a relatively low temperature into the condensation chamber 117; or, the water injection structure 51 can also be turned on only under the condition of not exceeding the maximum water volume requirement of the cooling water to inject the cooling water with a relatively low temperature into the condensation chamber 117 to reduce the water temperature of the cooling water in the condenser.

[0125] If there are abnormal situations such as damage or disconnection of the water pumping structure 50, there will be a problem that the water temperature of the cooling water has not improved after a period of time when the water change instruction is issued. At this time, the steps of reducing the heating power for cooking in the foregoing embodiment can be executed.

[0126] In some embodiments of the present application, after the step of sending the instruction to drain the condensation chamber 117 and inject water into the condensation chamber 117 after drainage, it includes:

[0127] Step S41, starting the water pumping structure 50 to drain the condensation chamber 117 for a first preset time;

[0128] Step S42, injecting water into the condensation chamber 117 for a second preset time.

[0129] In this embodiment, when starting the water pumping structure 50 to change the water in the condensation chamber 117, first start the water pumping structure 50 to drain the condensation chamber 117 for a first preset time; then inject water into the condensation chamber 117 for a second preset time to avoid a long water change process caused by simultaneous water addition and injection and improve the water change efficiency.

[0130] Please refer to Figure 1 and Figure 3 , the present invention also proposes a cooking appliance 100.

[0131] In some embodiments of the present application, the cooking appliance 100 includes an appliance main body 10 and a detection module 30. The appliance main body 10 includes a pot body assembly 11 and a top cover assembly 13. The top cover assembly 13 is disposed on the pot body assembly 11 in an openable and closable manner. A cooking space 115 is formed in the pot body assembly 11. One of the pot body assembly 11 and the top cover assembly 13 is provided with a condensation chamber 117, and the condensation chamber 117 can be communicated with the cooking space 115. The detection module 30 is disposed on the appliance main body 10 for detecting the cooling water information in the condensation chamber 117.

[0132] The cooking appliance 100 proposed in the present application can be an electric rice cooker, a pressure cooker, a steam box, a steam oven or other appliances that generate steam during the cooking process. The appliance main body 10 of the cooking appliance 100 includes a pot body assembly 11 and a top cover assembly 13. A cooking space 115 for placing and cooking food materials is formed in the pot body assembly 11. When the top cover assembly 13 is opened, the cooking space 115 can be exposed, facilitating the taking and placing of food materials. When the top cover assembly 13 is closed, the cooking space 115 is closed.

[0133] One of the pot body assembly 11 and the top cover assembly 13 forms a condensation chamber 117 communicated with the cooking space 115. The condensation chamber 117 can be provided in the pot body assembly 11 or in the top cover assembly 13. The condensation chamber 117 and the cooking space 115 can be communicated through a diversion channel 131, which can be conducted when the top cover assembly 13 is closed or always in a conductive state. When using the cooking appliance 100, cooling water can be stored in the condensation chamber 117 first, so that the steam generated during the cooking process of the cooking appliance 100 can flow into the condensation chamber 117 through the diversion channel 131 and contact 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 steam-free discharge during the cooking process, thereby avoiding the influence of steam on the surrounding environment and avoiding scalding users with steam. The process of steam entering the condensation chamber 117 and condensing is also a process of heat transfer and water addition. When the steam contacts the cooling water and condenses, the heat carried by the steam is transferred to the cooling water, which will cause the water temperature of the cooling water in the condensation chamber 117 to rise and increase the water volume in the condensation chamber 117. At this time, if the water temperature of the cooling water is too high, it will affect the condensation effect; if the water volume of the cooling water is small, it will also cause the cooling water to be quickly heated by the steam and the water temperature to be too high. If the water volume of the cooling water is high and higher than the highest water level line, as the steam continues to condense and the water volume of the cooling water increases, the problem of water overflow may occur.

[0134] In an embodiment of the present application, a detection module 30 is provided on the cooking appliance 100, and the detection module 30 is used to detect the state of the cooling water in the condensation chamber 117. For example, the detection module 30 can be a temperature detector, which can be directly inserted into the cooling water in the condensation chamber 117 to detect the water temperature of the cooling water, or can be arranged at an interval from the cooling water, such as at the opening position of the condensation chamber 117 or on the outer wall of the structure forming the condensation chamber 117; the detection module 30 can also be a water level detector, and the water level detector can detect the water level of the cooling water to determine the amount of the cooling water. With such a setting, when the cooling water does not meet the cooling requirements, the user or the control system can take corresponding actions, such as prompting the user to add water, reduce water or change water in the condensation chamber 117, or the control system drives the water pumping structure 50 to automatically add water, reduce water or change water; in addition, when it is confirmed that the information of the cooling water in the condensation chamber 117 cannot be changed temporarily, the boiling degree can be reduced and the steam emission can be reduced by heating and cooking at a second preset power. Thus, it is neither necessary to directly interrupt the cooking program, which may affect normal cooking, nor to cook at a normal power, which may cause a large amount of steam to enter the condensation chamber 117, resulting in the inability to condense in time when the water level of the cooling water is too low or the water temperature is too high, and the purpose of micro-steam or steam-free emission cannot be achieved; or there is a problem of water overflow in the condensation chamber 117 when the water level of the cooling water is too high.

[0135] In an embodiment of the present application, the detection module 30 includes a temperature detector;

[0136] And / or, the detection module 30 includes a water level detector.

[0137] In this embodiment, the detection module 30 is at least one of a temperature detector and a water level detector. The temperature detector can detect the water temperature of the cooling water. When the water temperature of the cooling water is too high and it is easy to cause a low condensation efficiency of the steam, the cooking appliance 100 can issue an instruction. The instruction can be a prompt signal for reminding the user to add water, reduce water or change water in the condensation chamber 117; or the control system drives the water pumping structure 50 to automatically add water, reduce water or change water; in addition, if the control system confirms that the information of the cooling water in the condensation chamber 117 cannot be changed temporarily, the boiling degree can be reduced and the steam emission can be reduced by heating and cooking at a second preset power.

[0138] The water level detector can detect the water level of the cooling water in the condensation chamber 117; if the water level of the cooling water is too high, when a large amount of steam enters the condensation chamber 117 for condensation, the water level in the condensation chamber 117 will rise rapidly, which is likely to cause the condensation chamber 117 to be filled with water and result in a problem of water overflow; if the water level in the condensation chamber 117 is too low, the cooling water is easily heated to a relatively high temperature by the steam, reducing the steam condensation efficiency, and a large amount of steam is likely to be discharged outward, and the purpose of micro-steam or steam-free cannot be achieved.

[0139] In an embodiment of the present application, the water level detector may be a weight detection structure or an infrared photosensitive detection structure, or both the weight detection structure and the infrared photosensitive detection structure may be provided simultaneously. Among them, when the weight detection structure is used as the water level detection structure, the total weight of the water tank 113 forming the condensation chamber 117 and the contents is detected to determine the water storage amount in the condensation chamber 117, thereby obtaining the water level height in the current condensation chamber 117. 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 determine the current water level height according to the received infrared ray signal.

[0140] Please refer to Figure 2 , in some embodiments of the present application, the cooking appliance 100 further includes a temperature sensor 70 for detecting the temperature of the cooking space 115.

[0141] In this embodiment, the cooking appliance 100 further includes a temperature sensor 70 for detecting the temperature of the cooking space 115. The temperature sensor 70 may be disposed outside the pot body 111 that forms the cooking space 115 in the cooking appliance 100, or may be disposed on the upper cover assembly 13 and at the opening position of the cooking space 115, or may be disposed directly in the cooking space 115 to detect the temperature of the food material. With such a setting, the temperature of the cooking space 115 can be detected by the temperature sensor 70 to confirm the cooking stage of the food material, and the operating states of various structures in the cooking appliance 100 can be controlled according to the cooking stage, such as controlling the heating duration and heating power of the heating structure, etc. In some embodiments, the condensation structure provided in the cooking appliance 100 can be controlled according to the cooking stage, such as the air-cooled heat dissipation or water-cooled heat dissipation structure, etc.; thereby facilitating improving the control accuracy of the cooking process.

[0142] Please refer to Figure 4 , in some embodiments of the present application, the cooking appliance 100 further includes a water pumping structure 50 disposed on the appliance main body 10 and communicating with the condensation chamber 117 to enable the condensation chamber 117 to intake and drain water.

[0143] In this embodiment, the water pumping structure 50 is provided on the cooking appliance 100. The water pumping structure 50 can be used to intake and drain water from the condensation chamber 117 to adjust the water temperature in the condensation chamber 117; in some embodiments, it can also be used to adjust the water volume in the condensation chamber 117.

[0144] For example, the water pumping structure 50 may include a water injection structure 51 and a drainage structure 53. The water injection structure 51 is in communication with an external water source, and the cold water from the external water source can be injected into the condensation chamber 117 by using the water injection structure 51 during the cooking process to reduce the water temperature in the condensation chamber 117 or to prevent the water temperature in the condensation chamber 117 from rising too fast due to the injection of steam, so that the steam has a high condensation efficiency after entering the condensation chamber 117. The drainage structure 53 can drain the water in the condensation chamber 117 to the outside of the cooking appliance 100, which can not only drain the relatively hot water in the condensation chamber 117 to realize the replacement of the water in the condensation chamber 117 and improve the water temperature adjustment effect on the condensation chamber 117, but also prevent the water level in the condensation chamber 117 from overflowing or affecting the entry of steam into the condensation chamber 117 due to the continuous replenishment of external cold water and the condensation of steam into water, thus playing a role in regulating the water volume in the condensation chamber 117. In addition, the water injection structure 51 and the drainage structure 53 can independently control the opening time and the 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 117. Of course, the water injection structure 51 and the drainage structure 53 can also operate in different time periods. For example, the drainage structure 53 can be opened first to drain the high-temperature cooling water in the condensation chamber 117, and then the water injection structure 51 can be opened to inject the relatively low-temperature cooling water into the condensation chamber 117. Or, only the water injection structure 51 can be opened to inject the relatively low-temperature cooling water into the condensation chamber 117 to reduce the water temperature of the cooling water in the condenser. 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 structure 50, and the positive and reverse rotation of the water pump is used to realize the water injection and drainage of the condensation chamber 117 respectively in different time periods.

[0145] In some embodiments, the water pumping structure 50 may be a water-cooling circulation structure. The water pumping structure 50 includes a circulation water pump and a water-cooling pipeline. Both ends of the water-cooling pipeline are in communication with the condensation chamber 117 to form a water circulation path. The circulation water pump provides power to drain the water in the condensation chamber 117 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 117. In this way, it can also play a role in regulating the water temperature in the condensation chamber 117 and prevent the water temperature in the condensation chamber 117 from rising too fast due to the injection of steam, so that the steam has a high condensation efficiency after entering the condensation chamber 117.

[0146] Please refer to Figure 4 , in some embodiments of the present application, the water pumping structure 50 includes:

[0147] A water injection structure 51, the water injection structure 51 is in communication with the condensation chamber 117 and can be used to connect to a water source to inject water into the condensation chamber 117; and

[0148] A drainage structure 53, the drainage structure 53 is in communication with the condensation chamber 117.

[0149] In this embodiment, the water pumping structure 50 includes a water injection structure 51 and a drainage structure 53. The water injection structure 51 is communicated with 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 communicated with the water source through the water pump 511, and the other end of the water inlet pipe 513 is communicated with the condensation chamber 117. 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 117 through the water inlet pipe 513 to reduce the water temperature in the condensation chamber 117 or prevent the water temperature in the condensation chamber 117 from rising too fast due to the injection of steam, so that the steam has a high condensation efficiency after entering the condensation chamber 117.

[0150] The drainage structure 53 includes a drainage pump 531 and a water outlet pipe 533. One end of the water outlet pipe 533 is communicated with the condensation chamber 117, and the other end is communicated with the drainage pump 531. When the drainage structure 53 is started, the drainage pump 531 can drain the water in the condensation chamber 117 to the outside of the cooking appliance 100 through the water outlet pipe 533, discharge the water with a higher temperature in the condensation chamber 117, realize the replacement of the water in the condensation chamber 117, and improve the water temperature adjustment effect of the condensation chamber 117; it also prevents the water level in the condensation chamber 117 from overflowing or affecting the entry of steam into the condensation chamber 117 due to continuous replenishment of external cold water and condensation of steam into water, and plays a role in adjusting the water volume in the condensation chamber 117.

[0151] In addition, the water injection structure 51 and the drainage structure 53 can independently control the opening time and closing time, 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 117. 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.

[0152] Please refer to Figures 1 to 4 , in some embodiments of the present application, the pot body assembly 11 includes a pot body 111 and a water tank 113 arranged side by side. A cooking space 115 is formed in the pot body 111, and a condensation chamber 117 is formed in the water tank 113. The upper cover assembly 13 is formed with a diversion channel 131, and the diversion channel 131 can conduct the cooking space 115 and the condensation chamber 117.

[0153] The cooking appliance 100 in the embodiments of the present application includes a pot body assembly 11 and an upper cover assembly 13. The pot body assembly 11 includes a pot body 111 and a water tank 113 arranged side by side. A cooking space 115 is formed in the pot body 111. The pot body 111 can include a housing and an inner liner, and the inner liner forms the cooking space 115. A heating structure can be arranged between the housing and the inner liner. A condensation chamber 117 is formed in the water tank 113. An air inlet can be opened at the top of the water tank 113. The upper cover assembly 13 can cover the water tank 113 and the pot body 111 simultaneously to close the condensation chamber 117 and the cooking space 115. An inlet 133 of a diversion channel 131 is arranged in the area of the upper cover assembly 13 facing the pot body 111, and an outlet 135 of the diversion channel 131 is arranged in the area of the upper cover assembly 13 facing the air inlet of the water tank 113. Thus, a relatively closed space can be formed by connecting the cooking space 115 and the condensation chamber 117 through the diversion channel 131, so that the steam generated in the cooking space 115 can enter the condensation chamber 117 through the diversion channel 131 for condensation.

[0154] Please refer to Figure 3 and Figure 4 , in some embodiments of the present application, the cooking appliance 100 further includes an air guide pipe 119. The air guide pipe 119 is arranged in the condensation chamber 117. One end of the air guide pipe 119 is communicated with the diversion channel 131, and the other end extends to the bottom of the condensation chamber 117.

[0155] In this embodiment, the air guide pipe 119 is arranged in the condensation chamber 117. The air guide pipe 119 forms an air guide channel 1191 with both ends penetrating for guiding the flow of steam, so that one end of the air guide pipe 119 is communicated with the diversion channel 131, and the other end extends to the bottom of the water tank 113 and is not higher than the lowest water level of the condensation chamber 117. With such an arrangement, when the cooking appliance 100 is in use, water not lower than the lowest water level is pre-added in the condensation chamber 117, so that the air outlet end of the air guide pipe 119 is submerged in the water. When cooking, the steam generated in the cooking space 115 can directly enter the water through the diversion channel 131 and the air guide pipe 119, so that the steam directly contacts the water and cools and condenses, improving the condensation efficiency of the steam.

[0156] Please refer to Figure 3 and Figure 4 , in some embodiments of the present application, the air outlet end of the air guide pipe 119 has an outwardly expanding air guide opening 1193;

[0157] and / or, the air guide pipe 119 further includes an extension section 1195. The extension section 1195 extends outward from the edge of the air outlet end of the air guide pipe 119 and is arranged opposite to the bottom wall of the condensation chamber 117.

[0158] In this embodiment, an outwardly expanding air guide port 1193 is provided at the air outlet end where the air guide pipe 119 extends to the bottom of the condensation chamber 117. The air guide port 1193 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 119, increase 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 117 reaches the position of the air guide pipe 119 and at least submerges the air guide port 1193, so that the steam slowly discharges from the air guide port 1193, reducing the steam flow rate and prolonging 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.

[0159] In an embodiment of the present application, it may also be that an extension section 1195 extends outward from the edge of the air outlet of the air guide pipe 119. The extension section 1195 is disposed opposite to the bottom wall of the condensation chamber 117. When the cooking appliance 100 is in use, the water level in the condensation chamber 117 reaches the position of the air guide pipe 119 and at least submerges the extension section 1195. With such a setting, when the steam flows out from the air guide channel 1191 of the air guide pipe 119, the steam is blocked by the extension section 1195 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 119. The setting of the extension section 1195 can prolong 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.

[0160] In some embodiments, the air guide port 1193 and the extension section 1195 can be provided simultaneously, with the extension section 1195 extending outward from the edge of the air guide port 1193, effectively improving the condensation effect of the steam in the condensation chamber 117.

[0161] 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 of the condensation chamber 117.

[0162] The present application also proposes a readable storage medium storing program instructions, which, when executed by a processor, implement the control method described in any of the foregoing embodiments.

[0163] Through the description of the above embodiments, those skilled in the art can clearly understand that the methods of the above embodiments can be implemented by means of software plus a necessary general hardware platform. Of course, they can also be implemented by hardware, but in many cases the former is a better implementation. Based on such an understanding, the technical solution of the present application, in essence, or the part that contributes to the prior art, can be embodied in the form of a software product.
