Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a control method, a control device, a controller and a cooking appliance. Background Art

[0002] This section merely provides background information related to the present disclosure and is not necessarily prior art.

[0003] Cooking appliances (such as automatic rice cookers) typically have multiple cooking modes. In some cooking modes, the cooking chamber of the cooking appliance needs to be cooled to meet the user's cooking needs. For example, when cooking low-sugar rice, the rice needs to be cooled and reheated during the cooking process to increase the resistant starch content in the rice, thereby meeting the user's low-sugar diet needs. In the prior art, a ventilation device is typically used to ventilate the cooking chamber to reduce the temperature within the cooking chamber, thereby producing low-sugar rice.

[0004] However, using a ventilation device to ventilate and cool the cooking cavity is a low-efficiency cooling method, resulting in a low content of resistant starch, which reduces the user experience. Summary of the Invention

[0089] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0090] It should be understood that the terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, as used herein, the singular forms "a," "an," and "the" may also be intended to include the plural forms. The terms "comprise," "include," and "have" are inclusive and, therefore, specify the presence of the stated features, elements, and / or components, but do not preclude the presence or addition of one or more other features, elements, components, and / or combinations thereof.

[0091] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Thus, features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0092] In the description of the present invention, unless otherwise specified or limited, the terms "disposed" and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integrated connections; they may refer to direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in the present invention based on specific circumstances.

[0093] For ease of description, spatial relative terms can be used in the text to describe the relationship of one element or feature relative to another element or feature as shown in the figure, such as "upper", "circumferential", "peripheral", "outer", "bottom", "back to", "top", "inner", etc. Such spatial relative terms are intended to include different orientations of the mechanism in use or operation in addition to the orientation depicted in the figure. For example, if the mechanism in the figure flips, the element described as "below other elements or features" or "below other elements or features" will then be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." can include both upper and lower orientations. The mechanism can be oriented otherwise (rotated 90 degrees or in other directions) and the spatial relative descriptors used in the text are interpreted accordingly.

[0094] like Figures 1 to 9As shown, the present invention proposes a control method for a cooking appliance 100, which is specifically used to cool down the food in the cooking cavity 121 during the cooking process. The control method of the cooking appliance 100 includes:

[0095] S1: Obtain the current state of the cooking appliance 100; S2: Determine whether the cooking cavity 121 of the cooking appliance 100 needs to be cooled down based on the current state of the cooking appliance 100; S3: Control the air cooling mechanism 30 and the water sprinkling mechanism 20 to cool down the cooking cavity 121 of the cooking appliance 100 according to the operating sequence based on the need for cooling down the cooking cavity 121 of the cooking appliance 100.

[0096] During the execution of step S1, the ingredients are placed in the cooking cavity 121 of the cooking appliance 100, and the cooking appliance 100 is started to cook the ingredients. During the cooking process, the cooking appliance 100 is inspected using the detection component of the cooking appliance 100, and the detection results are fed back to the controller 40, which receives the fed-back detection results.

[0097] It should be pointed out that when the user cooks the ingredients, the user inputs the required cooking mode into the cooking appliance 100 through human-computer interaction. The controller 40 matches the preset cooking parameters according to the cooking mode input by the user. The controller 40 controls the cooking process of the cooking appliance 100 according to the cooking parameters. During the cooking process, the acquisition module collects the current parameters of the cooking appliance 100 and feeds back the collected parameters to the controller 40.

[0098] In some embodiments of the present invention, the acquisition module detects the cooking cavity 121, and the detection parameters may be the cooking time and / or the temperature of the cooking cavity 121, so as to obtain the current state of the ingredients in the cooking cavity 121, thereby providing accurate data support for further control, so that the control accuracy is effectively guaranteed.

[0099] During the execution of step S2, the controller 40 compares the parameters collected by the acquisition module with the cooking parameters currently executed by the cooking appliance 100. The controller 40 uses the comparison result to further control the cooking appliance 100 to ensure the cooling effect of the cooking cavity 121, so that the quality of cooking is further improved.

[0100] For example, the collection module collects the cooking time of the cooking appliance 100, and the controller 40 compares the collected cooking time with the cooking time in the cooking parameters. When the collected cooking time does not reach the cooling starting point of the cooking time in the cooking parameters, the cooking cavity 121 does not need to be cooled down. When the cooking time reaches the cooling starting point of the cooking time in the cooking parameters, the cooking cavity 121 needs to be cooled down. For another example, the collection module collects the temperature of the cooking cavity 121, and the controller 40 compares the collected temperature with the preset cooling temperature in the cooking parameters. When the collected temperature does not reach the preset cooling temperature in the cooking parameters, the cooking cavity 121 does not need to be cooled down. When the collected temperature reaches the preset cooling temperature in the cooking parameters, the cooking cavity 121 needs to be cooled down.

[0101] During the execution of step S3, when the controller 40 determines that the cooking cavity 121 needs to be cooled, the controller 40 controls the air cooling mechanism 30 and the water sprinkling mechanism 20 respectively, so that the air cooling mechanism 30 and the water sprinkling mechanism 20 cool the cooking cavity 12 at different time node parameters, so that the air cooling mechanism 30 and the water sprinkling mechanism 20 operate alternately, that is, one runs and the other stops until cooking is completed.

[0102] It is further understood that step S3 specifically includes: S31: obtaining the status of the fan 31 of the air cooling mechanism 30; S32: according to the status of the fan 31 being the first preset state, controlling the air cooling mechanism 30 and the water sprinkling mechanism 20 to cool down the food in the cooking cavity 121 according to the first preset order of the operating sequence; S33: according to the status of the fan 31 being the second preset state, controlling the air cooling mechanism 30 and the water sprinkling mechanism 20 to cool down the food in the cooking cavity 121 according to the second preset order of the operating sequence, wherein the second preset state is different from the first preset state.

[0103] During the execution of step S31, the driving component of the air cooling mechanism 30 in the present invention is the fan 31. Under different cooking modes, the operating status of the fan 31 is different. The parameters of the fan 31 are collected by the acquisition module, and the status of the fan 31 is judged by the parameters of the fan 31. The operating sequence of the air cooling mechanism 30 and the water sprinkling mechanism 20 is set according to the status of the fan 31, so as to further improve the cooking effect.

[0104] It should be noted that the parameters of the fan 31 collected by the acquisition module may be data such as the speed of the fan 31, the operating current of the fan 31, and the operating voltage of the fan 31, so as to ensure the accuracy of the current state of the fan 31. In an embodiment of the present invention, the data collected by the acquisition module is the speed of the fan 31, and the current speed of the fan 31 is compared with a preset speed. When the current speed of the fan 31 is less than the preset speed, the fan 31 is in a first preset state (poor performance). When the current speed of the fan 31 is greater than or equal to the preset speed, the fan 31 is in a second preset state (good performance).

[0105] During the execution of step S32, the first preset state is that the fan 31 is in a poor operating condition. At this time, the performance of the fan 31 is poor. The controller 40 selects the first preset sequence in the operating sequence according to the current performance of the fan 31. The controller 40 runs the first preset sequence and controls the water sprinkling mechanism 20 and the air cooling mechanism 30 to cool the food in the cooking cavity 121 according to the first preset sequence to ensure the cooling effect in the cooking cavity 121, thereby improving the cooking quality of the food.

[0106] It should be pointed out that when the fan 31 is in the first preset state, its performance is poor. At this time, it is necessary to first use the water sprinkling mechanism 20 to cool the high-temperature water vapor in the cooking cavity 121 to avoid the adverse effects of the high-temperature water vapor on the fan 31, thereby reducing the failure rate of the fan 31 and reducing the user's usage cost.

[0107] During the execution of step S33, the second preset state is that the fan 31 is in a good operating condition. At this time, the performance of the fan 31 is good. The controller 40 selects the second preset order in the operating order according to the current performance of the fan 31, and controls the air cooling mechanism 30 and the water sprinkling mechanism 20 according to the second preset order to cool the food in the cooking cavity 121 to ensure the cooling effect in the cooking cavity 121, thereby improving the cooking quality of the food.

[0108] It should be pointed out that when the fan 31 is in the second preset state, its performance is better. At this time, the air cooling mechanism 30 needs to quickly remove the high-temperature water vapor in the cooking cavity 121 from the cooking cavity 121 to increase the cooling rate of the cooking cavity 121.

[0109] Furthermore, between step S31 and step S32, it also includes: S311: obtaining the fan speed in the state of fan 31; S312: comparing the fan speed with the preset speed; S313: judging that the state of fan 31 is the first preset state based on the fan speed being less than the preset speed; S314: judging that the state of fan 31 is the second preset state based on the fan speed being greater than or equal to the preset speed.

[0110] Specifically, the collection module is used to collect the operating speed of the fan 31 and the operating speed of the fan 31 is fed back to the controller 40. The controller 40 compares the operating speed of the fan 31 with the preset speed of the fan 31. When the operating speed of the fan 31 is less than the preset speed of the fan 31, it is determined that the fan 31 is in the first preset state (the performance of the fan 31 is poor). When the operating speed of the fan 31 is greater than or equal to the preset speed of the fan 31, it is determined that the fan 31 is in the second preset state (the performance of the fan 31 is good). The method of using the speed of the fan 31 to judge the performance of the fan 31 ensures the accuracy of the judgment, further ensures the cooling effect on the cooking chamber 121, and further improves the quality of cooking.

[0111] Furthermore, in step S32, it specifically includes: S321: obtaining the state of the fan 31 as the first preset state; S322: matching the first preset order of the operating sequence according to the state of the fan 31 as the first preset state; S323: according to the first preset order, first controlling the water sprinkling mechanism 20 to operate, and then controlling the air cooling mechanism 30 and the water sprinkling mechanism 20 to operate alternately.

[0112] When executing step 32, the fan 31 is in the first preset state. At this time, the performance of the fan 31 is poor. The controller 40 controls the water sprinkling mechanism 20 and the air cooling mechanism 30 according to the first preset sequence in the operation sequence. In the first preset sequence, the water sprinkling mechanism 20 is operated first and then the air cooling mechanism 30, and the two are operated alternately to cool the cooking cavity 121, so as to ensure that the cooking cavity 121 is effectively cooled and further avoid the drying and hardening of the ingredients.

[0113] Furthermore, in step S323, it specifically includes: S3231: controlling the water sprinkling mechanism 20 to intermittently spray water to cool the cooking cavity 121 multiple times according to the first preset time length; S3232: controlling the air cooling mechanism 30 to air cool the cooking cavity 121 of the cooking utensil 100 between two adjacent water sprinkling and cooling; S3233: after the water sprinkling mechanism 20 completes multiple water sprinkling, controlling the air cooling mechanism 30 to air cool the cooking cavity 121 of the cooking utensil 100.

[0114] When executing step S323, the fan 31 is in a first preset state. At this time, the performance of the fan 31 is poor. The controller 40 runs a first preset sequence. In the first preset sequence, the water sprinkling mechanism 20 is first controlled to start and run, and at a first preset time interval, the water sprinkling mechanism 20 is intermittently started and run to spray water and cool the cooking cavity 121 multiple times. Within the first preset time (at this time, the water sprinkling mechanism 20 is in a stopped state), the air cooling mechanism 30 is started and run. The water sprinkling mechanism 20 cools the cooking cavity 121 by sprinkling water into the cooking cavity 121. The air cooling mechanism 30 cools the cooking cavity 121 by taking the high-temperature water vapor in the cooking cavity 121 away from the cooking cavity 121. After completing multiple water sprinkling and cooling, the water sprinkling mechanism 20 stops running, and the air cooling mechanism 30 is run again to cool the cooking cavity 121 and then stopped. At this time, the cooling of the cooking cavity 121 is completed.

[0115] Taking the production of low-sugar rice as an example, the cooking process of the cooking appliance for low-sugar rice can include four stages, including: boiling stage, flushing stage, simmering stage, and heat dissipation stage. When the fan 31 of the air cooling mechanism 30 has poor performance and enters the heat dissipation stage, when the temperature starts to drop, the water spraying mechanism is first operated to reduce the influence of hot water vapor on the air cooling mechanism 30 by water spraying, and then the air cooling mechanism 30 is started to cool the rice. In order to improve the cooling effect, water spraying can be performed in stages. The general cooling process is as follows: the water spraying mechanism 20 sprays water on the cooking chamber 121 for the first time, and then sprays water. Mechanism 20 stops and air cooling mechanism 30 starts. After air cooling mechanism 30 runs for a first preset time (the first preset time can be set according to the specific usage environment, for example, 10s, 20s, or 30s), air cooling mechanism 30 stops and water sprinkling mechanism 20 starts again until water sprinkling mechanism 20 completes all water sprinkling times (20g to 100g of water each time, and the number of water sprinkling times is ≤5). Finally, air cooling mechanism 30 is run again to cool cooking chamber 121, and then air cooling mechanism 30 is stopped. At this point, cooling of cooking chamber 121 is completed. At this time, without increasing the performance cost of fan 31, the cooling effect is improved, thereby obtaining low-sugar rice with a better taste and a higher resistant starch content (adding water first to cool the rice can reduce the impact of high-temperature water vapor on fan 31. Adding water in stages can avoid the problem of adding water only once, resulting in water cooling the surface of the rice and the heat inside the rice being difficult to dissipate. It also avoids the problem of adding water all at once causing the rice to become soggy).

[0116] During the cooking process, five temperature collection points are set in the cooking cavity 121, namely the nozzle collection point, the first collection point, the second collection point, the third collection point and the fourth collection point. The temperature data of the five collection points during the cooking process are as follows:

[0124] The units of the data in Table 2 are all in °C. Figure 11 As shown, Figure 11 The temperature curve corresponding to Table 2.

[0125] Furthermore, in step S33, it specifically includes: S331: obtaining the state of the fan 31 as the second preset state; S332: matching the second preset order of the operation sequence according to the state of the fan 31 as the second preset state; S333: according to the second preset order, first controlling the air cooling mechanism 30 to operate, and then controlling the water sprinkling mechanism 20 and the air cooling mechanism 30 to operate alternately.

[0126] When executing step 33, the fan 31 is in the second preset state. At this time, the performance of the fan 31 is good. The controller 40 controls the water sprinkling mechanism 20 and the air cooling mechanism 30 according to the second preset sequence in the operation sequence. In the second preset sequence, the air cooling mechanism 30 is operated first and then the water sprinkling mechanism 20, and the two are operated alternately to cool the cooking cavity 121, so as to ensure that the cooking cavity 121 is effectively cooled and further avoid the drying and hardening of the ingredients.

[0127] Furthermore, in step S333, it specifically includes: S3331: controlling the air cooling mechanism 30 to air-cool the cooking cavity 121 of the cooking utensil 100 at a first preset speed; S3332: controlling the water sprinkling mechanism 20 to intermittently spray cooling water on the cooking cavity 121 multiple times according to a second preset time length; S3333: controlling the air cooling mechanism 30 to air-cool the cooking cavity 121 of the cooking utensil 100 at a second preset speed that is lower than the first preset speed between two adjacent water sprinkling and cooling; S3334: after the water sprinkling mechanism 20 completes multiple water sprinkling, controlling the air cooling mechanism 30 to air-cool the cooking cavity 121 of the cooking utensil 100 at a second preset speed.

[0128] It should be noted that, in the embodiment of the present invention, the first preset speed is between 9000 and 15000 r / min (excluding the endpoints), and the second preset speed is between 3000 and 9000 r / min (excluding the endpoints).

[0129] When executing step S333, the fan 31 is in the second preset state. At this time, the performance of the fan 31 is good. The controller 40 runs the second preset sequence. In the second preset sequence, the air cooling mechanism 30 is first controlled to start and run. Under the action of the fan 31, the high-temperature water vapor in the cooking cavity 121 is taken away from the cooking cavity 121. After the air cooling cools down for a period of time, the air cooling mechanism 30 stops running, and then the water spraying mechanism 20 is controlled to start and run. The water spraying mechanism 20 is intermittently started and run at a second preset time interval. The cooking cavity 121 is cooled by water spraying for multiple times. The air cooling mechanism 30 is started and operated within a second preset time period (at this time, the water spraying mechanism 20 is in a stopped state). The water spraying mechanism 20 cools the cooking cavity 121 by spraying water into the cooking cavity 121. The water spraying mechanism 20 and the air cooling mechanism 30 operate alternately to further cool the cooking cavity 121. After the water spraying mechanism 20 completes multiple water spraying cooling operations, the air cooling mechanism 30 is operated again to cool the cooking cavity 121 and then the air cooling mechanism 30 is stopped. At this time, the cooling of the cooking cavity 121 is completed.

[0130] Taking the preparation of low-sugar rice as an example, the cooking process of the cooking appliance for low-sugar rice may include: boiling stage, flushing stage, simmering stage, and heat dissipation stage. When the fan 31 has good performance and enters the heat dissipation stage, when the temperature starts to drop, the fan 31 of the air cooling mechanism 30 is first operated at the first preset speed condition (high speed) to cool the rice for a certain time (which can be set according to the specific use environment, for example, 10s, 20s or 30s, etc.), and then the water spraying mechanism sprays water to cool the rice. Similarly, in order to improve the cooling effect, water spraying can be performed in sections. The general cooling process is: the air cooling mechanism 30 first cools the cooking cavity 121 for a certain period of time, and after the air cooling mechanism 30 stops running, the water spraying mechanism 20 is controlled to start and run. To cool the cooking cavity 121 by spraying water, the water spraying mechanism 20 stops and the fan 31 of the air cooling mechanism 30 operates at a second preset speed (lowest efficiency). After the air cooling mechanism 30 has operated for a second preset duration (the second preset duration can be set according to the specific usage environment, for example, 10s, 20s, or 30s), the air cooling mechanism 30 stops and the water spraying mechanism 20 resumes operation until the water spraying mechanism 20 has completed all water spraying cycles (20g to 100g of water each time, with a water spraying frequency of ≤5). Finally, the air cooling mechanism 30 is resumed (with the fan 31 operating at the second preset speed) to cool the cooking cavity 121, and then the air cooling mechanism 30 is stopped, completing the cooling of the cooking cavity 121. This allows air cooling to first remove most of the heat from the pot before water spraying, improving cooling efficiency and resulting in low-sugar rice with a high resistant starch content. (Preliminary air cooling reduces high-temperature water vapor, which is significantly reduced when water is added, enhancing the cooling effect of water spraying.)

[0131] During the cooking process, five temperature collection points are set in the cooking cavity 121, namely the nozzle collection point, the first collection point, the second collection point, the third collection point and the fourth collection point. The temperature data of the five collection points during the cooking process are as follows:

[0139] The units of the data in Table 4 are all in °C. Figure 13 As shown, Figure 13 This is the temperature curve corresponding to Table 4.

[0140] In some embodiments of the present invention, during the manufacturing process of the cooking appliance 100, the fan 31 of the air cooling mechanism 30 is selected according to design requirements, and the operating order of the air cooling mechanism 30 and the water sprinkling mechanism 20 when the cooking cavity 121 is cooled is preset according to the performance of the selected fan 31. This operating order is the set order, and the air cooling mechanism 30 and the water sprinkling mechanism 20 of the cooking appliance operate alternately according to the set order to achieve cooling of the cooking cavity 121.

[0141] In some examples of this embodiment, when the performance of the fan 31 is poor, the controller 40 controls the water sprinkling mechanism 20 and the air cooling mechanism 30 according to a set order. During the control process, the water sprinkling mechanism 20 is controlled to operate first, and then the air cooling mechanism 30 is controlled to operate, and the two are operated alternately to cool the cooking cavity 121, so as to ensure that the cooking cavity 121 is effectively cooled, and further avoid the drying and hardening of the ingredients.

[0142] During the cooling process, it specifically includes: controlling the water sprinkling mechanism 20 to intermittently spray water to cool the cooking cavity 121 multiple times according to the first time threshold; controlling the air cooling mechanism 30 to air cool the cooking cavity 121 of the cooking utensil 100 between two adjacent water sprinkling and cooling processes; after the water sprinkling mechanism 20 completes multiple water sprinkling processes, controlling the air cooling mechanism 30 to air cool the cooking cavity 121 of the cooking utensil 100.

[0143] Specifically, the controller 40 runs a set sequence. In the set sequence of this example, the water sprinkling mechanism 20 is first controlled to start and run, and with the first time threshold as the time interval, the water sprinkling mechanism 20 is intermittently started and run to spray water to cool the cooking cavity 121 multiple times. Within the first time threshold (at this time, the water sprinkling mechanism 20 is in a stopped state), the air cooling mechanism 30 is started and run. The water sprinkling mechanism 20 cools the cooking cavity 121 by sprinkling water into the cooking cavity 121. The air cooling mechanism 30 cools the cooking cavity 121 by taking the high-temperature water vapor in the cooking cavity 121 away from the cooking cavity 121. After completing multiple water sprinkling and cooling, the water sprinkling mechanism 20 stops running, runs the air cooling mechanism 30 again to cool the cooking cavity 121, and then stops the air cooling mechanism 30. At this time, the cooling of the cooking cavity 121 is completed.

[0144] In some examples of this embodiment, when the performance of the fan 31 is good, the controller 40 controls the water sprinkling mechanism 20 and the air cooling mechanism 30 according to the set order. During the control process, the air cooling mechanism 30 is operated first and then the water sprinkling mechanism 20, and the two are operated alternately to cool the cooking cavity 121, so as to ensure that the cooking cavity 121 is effectively cooled, and further avoid the drying and hardening of the ingredients.

[0145] During the cooling process, it specifically includes: controlling the air cooling mechanism 30 to air-cool the cooking cavity 121 of the cooking utensil 100 at a first speed threshold; controlling the water sprinkling mechanism 20 to intermittently spray cooling water on the cooking cavity 121 multiple times according to a second time threshold; controlling the air cooling mechanism 30 to air-cool the cooking cavity 121 of the cooking utensil 100 at a second speed threshold that is less than the first speed threshold between two adjacent water sprinklings; after the water sprinkling mechanism 20 completes multiple water sprinklings, controlling the air cooling mechanism 30 to air-cool the cooking cavity 121 of the cooking utensil 100 at a second speed threshold.

[0146] Specifically, the controller 40 operates in a set sequence. In the set sequence of this example, the controller 40 first controls the air cooling mechanism 30 to start and operate, and under the action of the fan 31, the high-temperature water vapor in the cooking cavity 121 is taken away from the cooking cavity 121. After a period of air cooling, the air cooling mechanism 30 stops operating, and then controls the water sprinkling mechanism 20 to start and operate, and intermittently starts and operates the water sprinkling mechanism 20 at a second time threshold as a time interval to spray water to cool the cooking cavity 121 multiple times. Within the second time threshold (at this time, the water sprinkling mechanism 20 is in a stopped state), the air cooling mechanism 30 is started and operated, and the water sprinkling mechanism 20 cools the cooking cavity 121 by spraying water into the cooking cavity 121. The water sprinkling mechanism 20 and the air cooling mechanism 30 operate alternately to further cool the cooking cavity 121. After the water sprinkling mechanism 20 completes multiple water sprinkling coolings, the air cooling mechanism 30 is operated again to cool the cooking cavity 121 and then the air cooling mechanism 30 is stopped. At this time, the cooling of the cooking cavity 121 is completed.

[0147] It should be noted that, in the embodiment of the present invention, the first speed threshold is between 9000 and 15000 r / min (excluding the endpoints), and the second speed threshold is between 3000 and 9000 r / min (excluding the endpoints).

[0148] According to the control method for the cooking appliance 100 provided by the present invention, when cooking is performed using the cooking appliance 100, the current state of the cooking appliance 100 is determined to determine whether the cooking cavity 121 needs to be cooled. If the result of the determination is that the cooking cavity 121 needs to be cooled, the air cooling mechanism 30 and the water spraying mechanism 20 are controlled to start and operate in the operating sequence to cool the cooking cavity 121. By combining air cooling and water spraying to cool the cooking cavity 121, the food in the cooking cavity 121 is prevented from drying out and hardening, effectively improving the user experience.

[0149] like Figures 1 to 9 As shown, the present invention also provides a cooking appliance 100, which includes a controller 40, a body 10, an air cooling mechanism 30 and a water sprinkling mechanism 20. The body 10 is formed with a cooking cavity 121, and the cooking cavity 121 is used for cooking food. The air cooling mechanism 30 is communicated with the cooking cavity 121 for cooling the cooking cavity 121 with air. The water sprinkling mechanism 20 is communicated with the cooking cavity 121 for cooling the cooking cavity 121 with water. The controller 40 is electrically connected to the air cooling mechanism 30 and the water sprinkling mechanism 20 respectively.

[0150] Specifically, the air cooling mechanism 30, the water sprinkling mechanism 20 and the controller 40 are respectively provided on the body 10, and the air cooling mechanism 30 and the water sprinkling mechanism 20 are respectively communicated with the cooking cavity 121. When the cooking utensil 100 is used to cook food and the cooked food needs to be cooled down (for example, cooking low-sugar rice, etc.), the controller 40 obtains the current state of the cooking utensil 100 and determines whether the cooking cavity 121 needs to be cooled down according to the current state of the cooking cavity 121. When the cooking cavity 121 needs to be cooled down, the controller 40 further determines according to the current state of the air cooling mechanism 30. When the performance of the fan 31 of the air cooling mechanism 30 is poor, the controller 40 first controls the water sprinkling mechanism 20 to cool down the food. 0 to spray water to cool the cooking cavity 121 (water spraying can be performed in multiple times, and the air cooling mechanism 30 is operated between two adjacent water sprayings to cool the cooking cavity 121), and then the air cooling mechanism 30 is used to cool the cooking cavity 121; when the performance of the fan 31 of the air cooling mechanism 30 is good, the controller 40 first operates the air cooling mechanism 30 (at a high speed) to cool the cooking cavity 121, and then operates the water spraying mechanism 20 to spray water to cool the cooking cavity 121 (water spraying can be performed in multiple times, and the air cooling mechanism 30 is operated (at a low speed) to cool the cooking cavity 121 between two adjacent water sprayings), and finally the air cooling mechanism 30 is used to cool the cooking cavity 121.

[0151] In the process of cooling the cooking cavity 121, a combination of water cooling and air cooling is adopted. While ensuring the effective cooling of the ingredients, it avoids the ingredients in the cooking cavity 121 from drying out and hardening, thereby effectively improving the user experience.

[0152] In an embodiment of the present invention, the body 10 includes a pot body 14, a pot body 12 (a steamer 13 may be provided) and an upper cover 11 (the upper cover 11 includes a surface cover 111 and an inner cover 112). The pot body 12 is provided in the pot body 14, and a cooking cavity 121 is formed inside the pot body 12. The cooking cavity 121 is connected to the outside through an opening of the pot body 12. The upper cover 11 cooperates with the pot body 14 in an opening and closing manner for opening or closing the opening.

[0153] It should be pointed out that the pot body 12 and the pot body 14 can be a fixed structure or a detachable structure. In this embodiment, a accommodating cavity is provided on the pot body 14 (a heating component is provided in the accommodating cavity, and the heating component is, for example, a heating tube, an IH coil, and a heating plate, etc.), and the pot body 12 is arranged in the accommodating cavity in a detachable manner. When cooking is completed, the user can separate the pot body 12 from the pot body 14, thereby improving the convenience of the user during use.

[0154] In addition, the air cooling mechanism 30 includes a fan 31, which is installed in the upper cover 11 (the fan 31 is installed in the gas passage of the upper cover 11, and a sealing valve 32 is installed in the gas passage. The sealing valve 32 is used to connect or disconnect the gas passage to prevent the external environment from affecting the cooking chamber 121). One air outlet of the fan 31 is connected to the cooking chamber 121, and the other air outlet of the fan 31 is connected to the outside world. When the fan 31 is activated, it can blow outside air into the cooking chamber 121 or extract high-temperature water vapor in the cooking chamber 121 to cool the cooking chamber 121. In this embodiment of the present invention, the fan 31 extracts high-temperature water vapor from the cooking chamber 121, thereby preventing external impurities from entering the cooking chamber 121, ensuring good sanitary conditions in the cooking chamber 121 and effectively improving the cooking effect.

[0155] In other embodiments, the fan 31 can also be set on the pot body 14, and a gas channel connected to the fan 31 is provided on the pot body 14. The position where the gas channel is connected to the cooking cavity 121 is higher than the highest position of the food in the cooking cavity 121, thereby preventing the food in the cooking cavity 121 from overflowing through the gas channel.

[0156] In some embodiments of the present invention, the cooking appliance 100 also includes a food storage device, which is connected to the gas channel (the gas channel is provided in the upper cover 11 of the cooking appliance 100), and a receiving chamber is provided at the position where the gas channel is connected to the cooking cavity 121 (located on the side of the blocking valve 32 away from the cooking cavity 121). When the blocking valve 32 is closed, the fan 31 is started, and a negative pressure is formed in the gas channel. The food (rice, etc.) in the food storage device is sucked into the receiving chamber, the fan 31 stops running, and the blocking valve 32 opens. Under the action of gravity, the food enters the cooking cavity 121 through the gas channel, thereby realizing automatic delivery of food into the cooking cavity 121, and then realizing automatic cooking, which improves the user's convenience.

[0157] In addition, the water sprinkling mechanism 20 includes a water sprinkling member 21, a water pipe 23 and a water tank 22. The water sprinkling member 21 is provided on the upper cover 11 and is connected to the cooking cavity 121. The water tank 22 is connected to the water sprinkling member 21 through the water pipe 23. When it is necessary to spray water to cool the cooking cavity 121, the water in the water tank 22 is sent to the water sprinkling member 21 (a driving member such as a water pump can be provided) through the water pipe 23. The water is sprayed into the cooking cavity 121 through the water sprinkling member 21 (the water sprayed into the cooking cavity 121 can be in the form of water mist or water droplets, etc.) to achieve cooling of the cooking cavity 121.

[0158] It should be understood that the water sprinkling member 21 and the fan 31 are both arranged on the upper cover 11. When the cooking cavity 121 needs to be cooled, the water sprinkling member 21 sprays water into the cooking cavity 121 from top to bottom. The water enters the cooking cavity 121 under the action of gravity, which reduces energy consumption to a certain extent. At the same time, during the cooking process, the gas in the cooking cavity has lift. By arranging the fan 31 on the upper cover 11 and connecting it to the gas channel in the upper cover 11, the convenience of extracting the gas in the cooking cavity 121 is improved, and the energy consumption of the cooking appliance 100 is further reduced.

[0159] It should be pointed out that, in this embodiment, the sprinkler 21 includes a telescopic arm of a nozzle and a driving member. The telescopic arm is provided on the upper cover 11 and cooperates with the driving member in transmission. The nozzle is provided on the free end of the telescopic arm. Under the action of the driving member, the telescopic arm can make the nozzle approach or enter the food in the cooking cavity, so as to further improve the effect of cooling the cooking cavity, thereby improving the cooking quality of the cooking utensil, and further improving the user experience.

[0160] It should be noted that the embodiment of the present invention does not limit the specific type of the driving member. The driving member can be a linear drive motor, such as a wax motor, or a hydraulic drive device or a pneumatic drive device. The driving member drives the telescopic arm to retract or extend through a linear drive.

[0161] In the present invention, the cooking utensil 100 is an automatic rice cooker, etc. For the structures of other parts of the cooking utensil 100, please refer to the prior art, and the present invention will not elaborate on them here.

[0162] like Figure 7 As shown, the present invention further provides a control device 42 for a cooking appliance, which is used to execute the control method of the cooking appliance 100 as described above. The control device 42 of the cooking appliance 100 includes: an acquisition module 421, a judgment module 422, and a control module 423. During the cooking process of the cooking appliance 100, the acquisition module 421 acquires data of the cooking appliance 100 in real time so as to accurately obtain the current state of the cooking appliance 100. The judgment module 422 compares and judges the data acquired by the acquisition module 421, and determines whether the cooking cavity 121 currently needs to be cooled based on the comparison and judgment result. If the cooking cavity 121 is judged to need to be cooled, the control module 423 controls the air cooling mechanism 30 and the water sprinkling mechanism 20 to operate separately (the two do not operate at the same time), and cools the cooking cavity 121 by reasonably arranging the operation order of the two, so as to ensure that the cooking cavity can be cooled quickly and avoid the occurrence of food in the cooking cavity drying and hardening, thereby effectively improving the user experience.

[0163] Specifically, when using the cooking utensil 100 to cook ingredients, the acquisition module 421 acquires the current state of the cooking utensil 100 in real time, and the judgment module 422 judges the acquired current state of the cooking utensil 100. When the judgment result is that the cooking cavity 121 needs to be cooled, the control module 423 issues a control instruction to control the air cooling mechanism 30 and the water sprinkling mechanism 20 to cool the cooking cavity 121, thereby achieving the cooling of the ingredients and meeting the cooking needs.

[0164] The present invention also provides a controller 40, which includes a computer-readable storage medium 41 and a control device 42 according to the cooking appliance 100 as described above.
