Description

Technical Field

[0001] The present invention relates to the technical field of household appliance control, and in particular to a wind speed control method, device, equipment, medium and a steam oven for hot air baking. Background Art

[0002] With the continuous development of the home appliance industry, the easy-to-operate steam oven has become a familiar kitchen appliance. However, most steam ovens on the market today have problems with inconsistent cooking effects. These problems are related to the amount of food, the location of the food, and other reasons.

[0003] By observing the temperature of the food during cooking, it is not difficult to find that the reason for uneven cooking of food is the uneven temperature of the steam oven tank during cooking. In order to optimize and improve the cooking effect of food, many products have added hot air baking function. The principle is to increase the temperature of the tank by heating the heating tube, and then drive the temperature of the tank by the flow of wind, so that the temperature of the tank is evenly distributed, thereby achieving the purpose of improving the cooking effect of food. However, due to the fixed wind speed of the fan of the common hot air baking function, not all foods are suitable for hot air baking. The moisture of the food itself will be taken away during the hot air baking process, which will also cause the problem of poor food cooking effect. Summary of the invention

[0004] In view of this, the present invention provides a method, device, equipment, medium and steam oven for controlling the wind speed of hot air baking to solve the problem that the hot air wind speed cannot be adjusted, resulting in poor cooking effect.

[0005] In a first aspect, the present invention provides a method for controlling wind speed of hot air baking, the method comprising:

[0006] obtaining an initial food image of the placed food, and determining a target wind speed according to the initial food image;

[0007] Controlling the circulating fan to run at a target wind speed to generate hot air to bake the food, and obtaining a real-time food image of the food during the baking process;

[0008] Adjust the target speed based on the real-time image of the food until toasting is complete.

[0009] The wind speed control method for hot air baking provided by the embodiment of the present invention determines the target wind speed according to the initial food image of the placed food, forms hot air according to the target wind speed to bake the food, and adjusts the target wind speed according to the real-time food image during the baking process until the baking is completed. The present invention can determine whether the food is suitable for hot air baking by performing hot air baking according to the food image, and adjust the wind speed during the hot air baking process, thereby preventing excessive loss of food moisture, improving the cooking effect, and enhancing the user experience and satisfaction.

[0010] In an optional embodiment, before obtaining the initial food image of the placed food, it also includes: when the hot air baking function is turned on, obtaining the current wind speed control mode, the wind speed control mode includes: adjustable control mode and automatic control mode; judging whether the wind speed control mode is in the automatic control mode, if it is in the automatic control mode, obtaining the initial food image of the food.

[0011] The present invention can provide users with different cooking experiences by providing two wind speed control modes, allowing users to make choices based on their own cooking experience, thereby meeting their usage needs and improving their user experience.

[0013] The present invention determines the target wind speed according to the food type and food size, and can not only judge whether the food is suitable for hot air baking, but also adjust the wind speed according to the size of the food, so as to prevent the problem of poor cooking effect caused by baking at the same wind speed when the food is too large or too small.

[0014] In an optional embodiment, the target wind speed is adjusted according to the real-time food image until the baking is completed, including: obtaining the corresponding preset food cooking effect image in the preset image database according to the food type; comparing the real-time food image with the preset food cooking effect image to determine the cooking degree of the food; adjusting the target wind speed according to the cooking degree until the baking is completed.

[0015] The present invention can flexibly adjust the wind speed according to the cooking degree by judging the wrong cooking degree during the baking process, thereby preventing the food from being over-baked and causing excessive water loss, ensuring the food taste and improving the cooking effect.

[0017] The present invention allows the user to set the wind speed of hot air baking, which can satisfy the user's hands-on operation experience. When the user has rich cooking experience, he or she can choose a cooking method that is more suitable for food. At the same time, the number of uses is accumulated, so that the user's cooking habits can be accurately obtained and recorded.

[0018] In an optional implementation, after determining whether the user has set the current wind speed, the method further includes: if not set, obtaining a default rotation speed, and using the wind speed corresponding to the default rotation speed as the target wind speed.

[0019] The present invention adopts the default wind speed for baking when the user does not set the wind speed, so that cooking can be performed according to the user's usual cooking habits, thereby further improving the personalization and convenience of the user's experience.

[0020] In an optional embodiment, after acquiring the initial food image of the placed food, the method further includes: determining the placement position of the food according to the initial food image, and controlling the wind direction control device to adjust the air intake direction according to the placement position.

[0042] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0043] The embodiment of the present invention is applicable to the scenario where a user uses the hot air baking function of a steam oven to cook food, taking a dishwasher as an example. The embodiment of the present invention provides a wind speed control method for hot air baking, which adjusts the wind speed during the baking process to achieve the effect of improving the cooking effect.

[0044] According to an embodiment of the present invention, an embodiment of a method for controlling wind speed of hot air baking is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0045] In this embodiment, a method for controlling the wind speed of hot air baking is provided, which can be used in the above-mentioned steam oven. Figure 1 is a flow chart of a method for controlling wind speed of hot air baking according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0046] Step S101, obtaining an initial food image of the placed food, and determining a target wind speed according to the initial food image.

[0047] Specifically, in the embodiment of the present invention, after the user puts food into the steam oven and turns on the hot air baking function as required, the steam oven will provide the user with two wind speed control modes: an adjustable control mode and an automatic control mode. Figure 2As shown, for users with poor cooking experience, they can select the wind control gear (automatic gear) corresponding to the automatic control mode, and the steam-bake machine can collect food information and set the wind speed for baking by itself; while for users with better cooking ability, they can select the wind control gear (manual gear) corresponding to the adjustable control mode, and the user can set the wind speed for baking, which is only an example and not limited to this. When the user selects the automatic control mode, the main control MCU (Microcontroller Unit) of the steam oven controls the deployed camera device to shoot the food placed in the inner pot, and obtains the initial food image of the food shot by the camera based on the image recognition technology, and automatically determines the appropriate target wind speed based on the initial food image.

[0048] Step S102, controlling the circulating fan to run at a target wind speed to generate hot air to bake the food, and obtaining a real-time food image of the food during the baking process.

[0049] Specifically, in the embodiment of the present invention, after the target wind speed is determined, the heating tube of the steam oven starts to heat up, and the temperature of the steam oven inner tank rises. At the same time, the speed of the circulation fan is determined according to the target wind speed, and the circulation fan is controlled by PWM (Pulse Width Modulation) to operate according to the target wind speed, driving the heat of the steam oven inner tank to circulate, thereby baking the food with hot air.

[0050] In some optional embodiments, as baking progresses, the moisture of the food gradually disappears and the food gradually changes. Therefore, the steam oven of the embodiment of the present invention controls the camera by the main control MCU to capture real-time food images of the food in the inner pot at a certain frequency during the baking process.

[0051] Step S103, adjusting the target wind speed according to the real-time food image until baking is completed.

[0052] Specifically, in an embodiment of the present invention, the real-time food image collected records different states of the food during the baking process, and different states correspond to different cooking degrees of the food. For example, as the baking time increases, the color of the food surface may gradually deepen, or the volume of the food may gradually decrease due to the gradual loss of water, or meat food may gradually begin to produce oil due to baking. This is just an example and is not limited to this. The state of the food during the cooking process gradually begins to change as the cooking time increases. Therefore, the cooking degree corresponding to the real-time food image gradually deepens, and the moisture of the food will gradually decrease. In order to prevent excessive loss of moisture in the food and cause a poor taste, the embodiment of the present invention adjusts the initial target wind speed according to the real-time food image. As the cooking degree deepens, the wind speed gradually decreases until the baking is completed. At this time, both the food can be guaranteed to be cooked and the taste of the food can be guaranteed.

[0053] The wind speed control method for hot air baking provided by the embodiment of the present invention determines the target wind speed according to the initial food image of the placed food, forms hot air according to the target wind speed to bake the food, and adjusts the target wind speed according to the real-time food image during the baking process until the baking is completed. The present invention can determine whether the food is suitable for hot air baking by performing hot air baking according to the food image, and adjust the wind speed during the hot air baking process, thereby preventing excessive loss of food moisture, improving the cooking effect, and enhancing the user experience and satisfaction.

[0054] In this embodiment, a method for controlling the wind speed of hot air baking is provided, which can be used in the above-mentioned steam oven. Figure 3 is a flow chart of a method for controlling wind speed of hot air baking according to an embodiment of the present invention. Figure 3 As shown, the process includes the following steps:

[0055] Step S301, obtaining an initial food image of the placed food, and determining a target wind speed according to the initial food image.

[0056] Specifically, the above step S301 includes:

[0057] Step S3011, obtaining a preset food image from a preset image database.

[0058] Specifically, in the embodiment of the present invention, the main control MCU of the steam oven pre-establishes an image database, and the database stores images of food suitable for hot air baking, such as cake images, biscuit images, beef images, etc., which are only examples and are not limited to this. At the same time, suitable target wind speeds are set for different types of food in advance based on cooking experience, and different sizes of the same type of food are also set to different target wind speeds, and the target wind speeds and food images are stored in the image database at the same time. After the hot air baking function is turned on and the initial food image that needs to be cooked is obtained, the preset food image pre-stored in the image database is obtained.

[0059] Step S3012, comparing the initial food image with the preset food image to determine the food type and food size of the food.

[0060] Specifically, in the embodiment of the present invention, Figure 4 As shown, the main control MCU of the steam oven calls the food cooking image recognition function, and by comparing the initial food image with the preset food image, determines the most similar food, so as to determine the food information of the food that needs to be cooked, including: food type and food size, and the above food information can affect the setting of the wind speed. If the current food is a new type of baked snack, but its shape, size and color are similar to biscuits or cakes in the image database, the corresponding food information of biscuits or cakes is used as the food information of the current new type of baked snack.

[0061] Step S3013, determining the target wind speed according to the food type and food size.

[0062] Specifically, in an embodiment of the present invention, different types of food have different structures, moisture contents, and heat conduction characteristics, and therefore, suitable cooking methods and parameters are also different; the volume or thickness of food will also affect heat conduction and heat distribution. For example, larger foods may require lower wind speeds and longer cooking times so that heat can evenly penetrate the center of the food to avoid excessive drying of the surface while the inside is still raw; for small-volume foods or foods with low moisture content, higher wind speeds may be used to promote rapid surface formation and dehydration, by way of example only and not limited thereto. After determining the food type and size of the food currently being cooked, directly retrieve the target wind speed pre-set in the image database as the initial wind speed of the circulating fan this time, such as Figure 4 shown.

[0063] Step S302, determining the placement position of the food according to the initial food image, and controlling the wind direction control device to adjust the air intake direction according to the placement position.

[0064] Specifically, in the embodiment of the present invention, when a user puts food into the inner pot of the steam oven, the placement of the food may be different. In this case, in order to ensure that the food is evenly baked, an air inlet hood is deployed in the steam oven, and the air inlet hood can be used as a wind direction control device to adjust the air inlet direction of the circulating fan. The embodiment of the present invention determines the placement position of the food according to the initial food image, and adjusts the air inlet direction by controlling the air inlet hood, so that the wind generated by the circulating fan blows directly toward the food from the air outlet of the air inlet hood.

[0065] Step S303, control the circulating fan to run at the target wind speed to generate hot air to bake the food, and obtain a real-time food image of the food during the baking process. Figure 1 Step S102 of the illustrated embodiment will not be described in detail here.

[0066] Step S304, adjusting the target wind speed according to the real-time food image until baking is completed.

[0067] Specifically, the above step S304 includes:

[0068] Step S3041, obtaining the corresponding preset food cooking effect image in the preset image database according to the food type.

[0069] Specifically, in an embodiment of the present invention, the state changes of the food cooking process are stored in an image database in advance in the form of food cooking completion effect images. After the error type is determined based on the initial food image and the preset food image, multiple food cooking completion effect images corresponding to the preset food image can be directly obtained according to the food type.

[0070] Step S3042, comparing the real-time food image with the preset food cooking effect image to determine the cooking degree of the food.

[0071] Specifically, in an embodiment of the present invention, the main control MCU compares the real-time food image captured by the camera device with each food cooking effect image, and determines the target food cooking effect image that is closest in color, thereby determining the cooking degree of the food based on the target food cooking effect image, for example, the current cooking is 50% completed.

[0072] Step S3043, adjusting the target wind speed according to the degree of cooking until baking is completed.

[0073] Specifically, in the embodiment of the present invention, Figure 4 As shown, in order to avoid over-baking of food, the real-time cooking degree is determined according to the real-time food image during the cooking process, so that the target wind speed is dynamically adjusted according to the cooking degree. For example, the wind speed can be adjusted to a percentage of the target wind speed according to the percentage of the cooking degree. This is only an example and is not limited to this.

[0074] The wind speed control method for hot air baking provided by the embodiment of the present invention determines the target wind speed according to the initial food image of the placed food, forms hot air according to the target wind speed to bake the food, and adjusts the target wind speed according to the real-time food image during the baking process until the baking is completed. The present invention can determine whether the food is suitable for hot air baking by performing hot air baking according to the food image, and adjust the wind speed during the hot air baking process, thereby preventing excessive loss of food moisture, improving the cooking effect, and enhancing the user experience and satisfaction.

[0075] In this embodiment, a method for controlling the wind speed of hot air baking is provided, which can be used in the above-mentioned steam oven. Figure 5 is a flow chart of a method for controlling wind speed of hot air baking according to an embodiment of the present invention. Figure 5 As shown, the process includes the following steps:

[0076] Step S501: when the hot air baking function is turned on, obtain the current wind speed control mode, which includes: adjustable control mode and automatic control mode; and determine whether the wind speed control mode is in automatic control mode. Figure 1 Step S101 of the illustrated embodiment will not be described in detail here.

[0077] Step S502: If the system is in the adjustable control mode, determine whether the user has set the current wind speed.

[0078] Specifically, in the embodiment of the present invention, users with high cooking experience are more inclined to control the steam oven according to their own experience, so they will set the current wind speed after selecting the manual gear corresponding to the adjustable control mode. The steam oven in the embodiment of the present invention provides a maximum selectable wind speed of 2000, a minimum of 0, and an adjustable wind speed value of an integer multiple of 100, thereby reducing the wind speed value and facilitating the steam oven to store the wind speed value.

[0079] Step S503, if set, obtain the current wind speed and record the working time of the current wind speed.

[0080] Specifically, in the embodiment of the present invention, Figure 6 As shown, if the user sets the current wind speed according to the food to be cooked, and after placing the food and closing the door, the steam oven starts to run at the current wind speed and starts to record the working time at the current wind speed.

[0081] Step S504: if the working time exceeds the preset time, the current wind speed is used as the target wind speed, and the number of times the fan speed corresponding to the current wind speed is used is accumulated.

[0082] Specifically, in the embodiment of the present invention, when it is determined that the accumulated working time T exceeds a preset time, for example, 10 seconds, the current wind speed is used as the final target wind speed. At the same time, when the working time T>10 seconds, the number of times the circulating fan speed corresponding to the current wind speed is accumulated and memorized. The judgment of the working time can avoid the accumulation of incorrect usage times when the user sets the speed incorrectly.

[0083] Step S505, sorting the fan speeds according to the number of times used, and taking the fan speed corresponding to the maximum number of times used as the default speed.

[0084] Specifically, in the embodiment of the present invention, the main control MCU sorts the fan speeds corresponding to the usage times from large to small, and updates the fan speed corresponding to the maximum usage times to the default speed, which is used as the user's cooking habit. Figure 6 As shown, after multiple cooking times, a default speed already exists, so the number of times the current speed is used is directly compared with the stored number of times. If the current wind speed is used the highest number of times, the default wind speed is directly updated with the current wind speed. If it is not the highest, the default wind speed is not updated.

[0085] In some optional embodiments, when the user selects an adjustable control mode but does not set the current wind speed, the embodiment of the present invention uses the wind speed corresponding to the default speed as the target wind speed and bakes the food directly according to the target speed, which can provide convenience when the user repeatedly bakes the same type of food for a long time.

[0086] The wind speed control method for hot air baking provided by the embodiment of the present invention obtains the current wind speed set by the user and records the working time of the current wind speed. When the preset time is exceeded, the current wind speed is used as the target wind speed, and the number of times the fan speed corresponding to the current wind speed is accumulated, and the fan speed corresponding to the maximum number of times is used as the default speed. The present invention can provide users with a personalized cooking experience by setting an adjustable wind speed control mode, and can provide convenience for users by accumulating the number of times the wind speed is used, thereby improving the user's experience and satisfaction.
