Abstract
Description
Technical Field
[0001] This application relates to the field of kitchen utensil technology, and more particularly to a cooking utensil. Background Technology
[0002] This section is intended to provide background or context for the embodiments described in this application. The description herein is not intended to be a prior art simply because it is included in this section.
[0003] Rice cookers typically cook food at a fixed time, and the cooking concentration cannot be adjusted. When cooking small amounts, more water evaporates, resulting in a cooking concentration far exceeding the set concentration; while when cooking large amounts, insufficient boiling leads to a lower concentration. Therefore, this can easily result in food with a poor texture.
[0004] In related technologies, radar sensors can be used to detect the cooking state of food, thereby achieving more precise control over boiling state and cooking concentration to improve the taste of the food. However, based on different application scenarios and the need for higher detection accuracy, the settings of the radar sensors need to be adjusted. Utility Model Content
[0005] In view of this, the embodiments of this application aim to provide a cooking appliance that can improve the detection accuracy of the cooking appliance and also help the cooking appliance meet the cooking needs in more scenarios.
[0006] To solve the above problems, the technical solution of this application embodiment is implemented as follows:
[0007] This application provides a cooking appliance, including:
[0008] The pot body assembly is provided with a cooking cavity, the top side of which is open and forms a food loading and unloading port;
[0009] A lid assembly has an open state and a closed state; in the closed state, the lid assembly covers the food opening; in the open state, the lid assembly opens the food opening.
[0010] A radar sensor assembly is used to acquire cooking parameters at at least two different locations of the cooking appliance.
[0011] In some embodiments, the cover assembly is provided with a steam channel, and in the closed state, the cooking cavity is connected to the atmosphere through the steam channel, and the detection range of the radar sensor assembly covers at least a portion of the steam channel and at least a portion of the cooking cavity.

[0013] The first radar sensor is located on the cover assembly, and the second radar sensor is located on the cover assembly or the pot assembly.
[0014] In some embodiments, when projecting along the height direction of the cooking appliance, the orthographic projection of the first radar sensor is located within the orthographic projection range of the steam flow channel, while the orthographic projection of the second radar sensor is located outside the orthographic projection range of the steam flow channel but within the orthographic projection range of the food loading / unloading port.
[0015] In some embodiments, the steam channel has an air inlet and an air outlet, the air outlet being in communication with the atmosphere, and in the closed state, the cooking cavity is in communication with the steam channel through the air inlet;
[0016] Projecting along the height direction of the cooking appliance, at least a portion of the orthographic projection of the first radar sensor lies within the range of the orthographic projection of the air inlet.
[0017] In some embodiments, the radar sensor assembly includes multiple signal transmission surfaces, each of which is capable of receiving and transmitting radar signals. The detection range of a portion of the signal transmission surfaces covers at least a portion of the steam flow channel, and the detection range of another portion of the signal transmission surfaces covers at least a portion of the cooking cavity.
[0018] In some embodiments, the radar sensor assembly includes a first radar sensor and a second radar sensor, which respectively acquire cooking parameters at different locations of the cooking appliance.
[0019] In some embodiments, the cooking cavity includes a first cooking cavity and a second cooking cavity, wherein the detection range of the first radar sensor covers at least a portion of the first cooking cavity, and the detection range of the second radar sensor covers at least a portion of the second cooking cavity.
[0020] In some embodiments, both the first radar sensor and the second radar sensor are located on the cover assembly; or,
[0021] The first radar sensor is located on the cover assembly, and the second radar sensor is located on the pot assembly.
[0022] In some embodiments, the first radar sensor and the second radar sensor detect cooking parameters at different locations within the cooking cavity, respectively.
[0023] In some embodiments, the cooking appliance further includes a control module and an electrical connection wire, and the radar sensor assembly is electrically connected to the control module via the electrical connection wire; or,
[0024] The cooking appliance also includes a control module, and the radar sensor assembly is wirelessly connected to the control module.
[0025] In some embodiments, the radar sensor assembly includes multiple signal transmission surfaces, each of which is capable of receiving and transmitting radar signals, and the multiple signal transmission surfaces are used to acquire cooking parameters at at least two different locations of the cooking appliance.
[0026] The cooking appliance of this application embodiment acquires cooking parameters at at least two different locations using a radar sensor assembly. On the one hand, the superposition and coordination of multiple sets of cooking parameters can amplify slight fluctuation signals, thereby detecting more cooking parameters. This helps the cooking appliance to more accurately determine the cooking stage of the food in the cooking cavity, which in turn improves the detection accuracy of the cooking appliance and allows for more accurate control of the cooking concentration to improve the taste of the food. On the other hand, the radar sensor assembly can simultaneously acquire cooking parameters of multiple foods, as well as cooking parameters of foods under multiple cooking functions. This allows the cooking appliance to meet cooking needs in more scenarios, thereby improving the user experience. Attached Figure Description

[0042] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0043] Rice cookers typically cook food for a fixed time. Because they use traditional thermistor sensors to detect temperature, and to prevent overflow during cooking, they control the heating using a fixed curve, making it impossible to adjust the cooking concentration. When cooking small amounts, more water evaporates, resulting in a concentration far exceeding the set limit; while when cooking large amounts, insufficient boiling leads to a lower concentration. Therefore, this often results in food with a poor texture.
[0044] In view of this, the present application provides a cooking utensil.
[0045] Cooking appliances can be, for example, rice cookers, electric pressure cookers, electric slow cookers, etc., and this application does not limit them.
[0046] Please see Figures 1 to 5 The cooking appliance includes a pot body assembly 10, a lid assembly 20, and a radar sensor assembly.
[0047] The pot body assembly 10 is provided with a cooking cavity 11a, the top side of which is open and forms a food loading / unloading port 11b. Food is cooked in the cooking cavity 11a, and the food loading / unloading port 11b is used to put ingredients into the cooking cavity 11a or to take food out of the cooking cavity 11a.
[0048] It should be noted that in the embodiments of this application, when referring to directional descriptions such as "upper," "lower," "top," and "bottom," they should be understood in conjunction with the height direction of the cooking utensil, which must be understood based on its actual usage. For example, the height direction of the cooking utensil is... Figure 1 , Figure 3 , Figure 4or Figure 6 The direction indicated by H in the middle.
[0049] The specific structure of the pot body assembly 10 is not limited.
[0050] Exemplarily, the pot assembly 10 includes an inner pot 11 and an outer shell 12. The outer shell 12 has a receiving cavity, and the inner pot 11 has a cooking cavity 11a and a food loading / unloading port 11b. At least a portion of the inner pot 11 is disposed within the receiving cavity, and the inner pot 11 can be removed from the receiving cavity. This facilitates cleaning of the cooking cavity 11a by the user. Please refer to... Figure 6 Here, the top wall 111 of the inner pot is surrounded to form a food loading and unloading opening 11b.
[0051] The cover assembly 20 has an open state and a closed state; in the closed state, the cover assembly 20 covers the food opening 11b; in the open state, the cover assembly 20 opens the food opening 11b.
[0052] For example, when cooking food, the cover assembly 20 is in the closed state and covers the food loading and unloading port 11b, which can effectively improve the problem of hot juice splashing out in the cooking cavity 11a. This makes it safer and easier to clean.
[0053] For example, when the cooking appliance is not in use, the lid assembly 20 is in a closed state and covers the food inlet 11b, thereby effectively reducing the problem of dust and other stains entering the cooking cavity 11a, which is beneficial to health.
[0054] For example, when it is necessary to put ingredients into the cooking cavity 11a or take out food, the cover assembly 20 switches to the open state, and the food loading and unloading port 11b is opened, thus facilitating user operation.
[0055] The specific structure used to switch the cover assembly 20 between the open and closed states is not limited.
[0056] In some embodiments, one side of the lid assembly 20 is rotatably disposed on the pot body assembly 10, and the lid assembly 20 switches between an open state and a closed state by rotating about this rotatable side.
[0057] It is understood that in this embodiment, the lid assembly 20 is connected to the pot body assembly 10 regardless of whether it is in the open or closed state. In this way, after the user operates the lid assembly 20 to open the food loading and unloading port 11b, there is no need to find a temporary place to put the lid assembly 20, which helps to improve the user experience.
[0058] In other embodiments, the lid assembly 20 is in the open state and can be separated from the pot body assembly 10. That is, the lid assembly 20 can be removed from the pot body assembly 10 as a whole, which makes it convenient for the user to clean the lid assembly 20.
[0059] The radar sensor assembly is used to acquire cooking parameters at at least two different locations on the cooking appliance.
[0060] It should be noted that cooking parameters include, but are not limited to, the intensity of steam flow, the fluctuation of the food surface or water surface, etc.
[0061] The specific method by which the radar sensor assembly acquires cooking parameters at at least two different locations on the cooking appliance is not limited.
[0062] For example, the radar sensor assembly includes a plurality of radar sensors 30, each radar sensor 30 acquiring cooking parameters at different locations of the cooking appliance.
[0063] It should be noted that in the embodiments of this application, "multiple" refers to any number of two or more.
[0064] For example, the radar sensor assembly includes a first radar sensor 40 and a second radar sensor 50, which respectively acquire cooking parameters at different locations of the cooking appliance.
[0065] In this way, cooking parameters at different locations are acquired by different radar sensors 30. For a single radar sensor 30, the installation of the radar sensor 30 can only consider the cooking parameters at one location, thus making the installation of the radar sensor 30 more convenient.
[0066] For example, the radar sensor assembly includes multiple signal transmission surfaces 31, each capable of receiving and transmitting radar signals. These multiple signal transmission surfaces 31 are used to acquire cooking parameters at at least two different locations on the cooking appliance. That is, each signal transmission surface 31 can acquire cooking parameters at different locations.
[0067] Here, the radar sensor assembly may include only one radar sensor 30, which has multiple signal transmission surfaces 31.
[0068] Of course, the radar sensor assembly here may also include multiple radar sensors 30, each radar sensor 30 having one or more signal transmission surfaces 31, so that the radar sensor assembly may also have multiple signal transmission surfaces 31.
[0069] The radar signal leaves the radar sensor 30 through the outer surface of the radar sensor 30. The outer surface of the radar sensor 30 through which the radar signal passes during its departure is the signal transmission surface 31.
[0070] Specifically, a signal terminal can be provided on the radar sensor 30, and the signal transmission surface 31 is the outer surface of the signal terminal.
[0071] In related technologies, traditional thermistor sensors are used to sense temperature for cooking control. However, since the temperature does not change abruptly, it is impossible to determine the number of boiling times in a short period of time.
[0072] The cooking appliance of this application embodiment acquires cooking parameters at at least two different locations using a radar sensor assembly. The radar sensor assembly can emit radar signals and receive reflected signals, thereby detecting waveforms of solids, liquids, or gases. For example, changes in waveform frequency can detect fluctuations in the water or food surface, the intensity of steam flow, etc., and these cooking parameters can be used to determine whether the cooking process is boiling or not. By quickly determining the boiling or non-boiling state, rapid heating and stopping of the cooking process are achieved.
[0073] For example, one boil from the state of boiling to the state of stopping is considered as one effective boil. The number of times of high heat boiling is set according to the concentration and taste set at the beginning of cooking. The more concentrated the taste, the greater the number of times of high heat boiling is set. When the actual number of boilings during the cooking process is equal to the set number of times, the minimum heating amount is used to maintain the specific temperature.
[0074] In other words, cooking utensils can achieve a number of boiling times in a short period of time, thereby enabling more precise control of the cooking concentration, which is beneficial to improving the taste of food.
[0075] In related technologies, when only cooking parameters at the same location of the cooking appliance are acquired, the detection accuracy of the cooking appliance is poor; furthermore, when the cooking appliance cooks multiple foods at the same time or performs multiple functions such as steaming, boiling, frying, sautéing, and stewing at the same time, the cooking appliance is difficult to control.
[0076] The cooking appliance in this embodiment acquires cooking parameters at at least two different locations using multiple radar sensor components. On one hand, the superposition and cooperation of multiple sets of cooking parameters can amplify slight fluctuation signals, thereby detecting more cooking parameters. This helps the cooking appliance to more accurately determine the cooking stage of the food in the cooking cavity 11a, which improves the detection accuracy of the cooking appliance and allows for more accurate control of the cooking concentration to improve the taste of the food. On the other hand, the radar sensor components can simultaneously acquire cooking parameters of multiple foods, as well as cooking parameters of foods under multiple cooking functions. This allows the cooking appliance to meet cooking needs in more scenarios, thereby improving the user experience.
[0077] In some embodiments, please refer to Figure 1 and Figure 2 The cover assembly 20 is provided with a steam channel 20a. When the cover is closed, the cooking cavity 11a is connected to the atmosphere through the steam channel 20a. The detection range of the radar sensor assembly covers at least a portion of the steam channel 20a and at least a portion of the cooking cavity 11a.
[0078] Here, the radar sensor assembly can acquire cooking parameters such as the intensity of steam flow in the steam channel 20a and the fluctuation of food or water surface in the cooking chamber 11a.
[0079] In this way, by acquiring different types of cooking parameters, it is beneficial to further improve the detection accuracy of cooking utensils, so as to achieve more precise control of cooking concentration.
[0080] In some embodiments, the radar sensor assembly includes multiple signal transmission surfaces 31, each capable of receiving and transmitting radar signals. A portion of the signal transmission surfaces 31 have a detection range covering at least a portion of the steam flow channel 20a, while another portion covers at least a portion of the cooking cavity 11a. These multiple signal transmission surfaces 31 may belong to the same radar sensor 30 or to different radar sensors 30.
[0081] In other embodiments, please refer to Figure 1 and Figure 2 The radar sensor assembly includes a first radar sensor 40 and a second radar sensor 50. The detection range of the first radar sensor 40 covers at least a portion of the steam flow channel 20a, and the detection range of the second radar sensor 50 covers at least a portion of the cooking cavity 11a. The first radar sensor 40 is disposed on the lid assembly 20, and the second radar sensor 50 is disposed on the lid assembly 20 or the pot assembly 10.
[0082] In this way, cooking parameters in the steam flow channel 20a and cooking cavity 11a are obtained by two radar sensors 30 respectively. Compared with the embodiment that uses multiple signal transmission surfaces 31 of one radar sensor 30, the first radar sensor 30 and the second radar sensor 40 do not interfere with each other and can be installed independently, thus making installation more convenient.
[0083] In some embodiments, please refer to Figure 1 and Figure 2 Projecting along the height direction of the cooking appliance, the orthographic projection of the first radar sensor 40 is within the orthographic projection range of the steam flow channel 20a, while the orthographic projection of the second radar sensor 50 is outside the orthographic projection range of the steam flow channel 20a but within the orthographic projection range of the food loading / unloading port 11b.
[0084] It should be noted that, in the embodiments of this application, when the radar sensor 30 is placed on the cover assembly 20 and projected along the height direction of the cooking appliance, it is understood that the cover assembly 20 is in a closed state.
[0085] Understandably, the radar sensor 30 is typically installed from top to bottom along the height of the cooking appliance. In this embodiment, the bottom wall surface of the radar sensor 30 can be set as the signal transmission surface 31, with the direction perpendicular to this signal transmission surface 31 as the reference direction. The signal transmission surface 31 transmits radar signals along its corresponding reference direction. Therefore, the projected area of the radar sensor 30 along the height of the cooking appliance is the detection range of the radar sensor 30.
[0086] In this way, during the installation process, the installer can more easily confirm whether the radar sensor 30 is installed in place, which helps to improve the installation success rate of the radar sensor 30.
[0087] In some embodiments, please refer to Figure 1 and Figure 2 The steam flow channel 20a has an air inlet 20b and an air outlet 20c. The air outlet 20c is connected to the atmosphere. When the lid is closed, the cooking cavity 11a is connected to the steam flow channel 20a through the air inlet 20b.
[0088] In other words, when the lid is closed, the steam generated in the cooking cavity 11a can enter the steam channel 20a through the air inlet 20b and leave the steam channel 20a through the air outlet 20c to enter the atmosphere.
[0089] Projected along the height of the cooking appliance, at least a portion of the orthographic projection of the first radar sensor 40 lies within the range of the orthographic projection of the air inlet 20b.
[0090] For example, the orthographic projection of the first radar sensor 40 may be entirely within the range of the orthographic projection of the air intake 20b.
[0091] For example, a portion of the orthographic projection of the first radar sensor 40 may be within the range of the orthographic projection of the air inlet 20b, while another portion may be outside the range of the orthographic projection of the air inlet 20b.
[0092] In this embodiment, the first radar sensor 40 can acquire cooking parameters of the intensity of steam flow at the air inlet 20b. The flow cross-section at the air inlet 20b is smaller than that in the steam channel 20a. At the air inlet 20b, the steam is more concentrated, and the steam state is more accurately reflected, which helps to improve the accuracy of the data acquired by the first radar sensor 40.
[0093] In some embodiments, please refer to Figures 1 to 3 , Figure 7 Each radar sensor 30 has an outer wall including a signal transmission surface 31, with the direction perpendicular to the signal transmission surface 31 as the reference direction, and the radar signal can be transmitted at least along the reference direction; the radar sensor 30 provided on the cover assembly 20 is a cover radar sensor, and the signal transmission surface 31 of the cover radar sensor is not perpendicular to the surface where the food opening 11b is located.
[0094] For example, the signal transmission surface 31 can be the bottom surface of the radar sensor 30.
[0095] That is, there is a first angle between the signal transmission surface 31 and the surface where the food pick-up and put-out port 11b is located, and the first angle is greater than or equal to 0° and less than 90°. For example, it is 0°, 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, 89°, etc.
[0096] It should be noted that when the first included angle is 0°, the signal transmission surface 31 is parallel to the surface where the food loading and unloading port 11b is located.
[0097] It is understandable that when the two surfaces are set at an angle, two angles, a first angle and a second angle, will be formed on one side of the signal transmission surface 31. The sum of the angles of these two angles is , and the first angle is the smaller angle.
[0098] In this embodiment, the angle of the first included angle can be adjusted according to the specific setting position of the radar sensor 30. When the radar signal is used to detect the fluctuation of food or water surface in the cooking cavity 11a, it is beneficial for the radar signal to enter the cooking cavity 11a through the food loading and unloading port 11b, reducing the interference of the components constituting the cooking cavity 11a (i.e., the inner pot 11) on the radar signal, and improving the accuracy of the cooking status of the food detected by the radar sensor 30.
[0099] It should be noted that there is no limit to the number of signal transmission surfaces 31 provided on a radar sensor 30.
[0100] In some embodiments, a radar sensor 30 may be provided with only one signal transmission surface 31, which can also satisfy the detection of the cooking status of food.
[0101] In other embodiments, please refer to Figure 7 Each radar sensor 30 is provided with multiple signal transmission surfaces 31.
[0102] For example, please refer to Figure 7 The bottom and side walls of the radar sensor 30 are both signal transmission surfaces 31.
[0103] Each signal transmission surface 31 can receive and transmit radar signals. Therefore, any one signal transmission surface 31 can independently acquire cooking parameters.
[0104] In this embodiment, the specific number of signal transmission surfaces 31 can be designed according to the specific control method of the cooking appliance. Multiple signal transmission surfaces 31 work independently and form a backup for each other. In this way, the problem of the cooking appliance being unable to complete the detection of the cooking status of the food due to the failure of one signal transmission surface 31 is avoided, which helps to improve the reliability of the cooking appliance.
[0105] Each signal transmission surface 31 can detect cooking parameters at different locations. In this way, a more accurate judgment of the cooking state can be achieved based on multiple cooking parameters.
[0106] In some embodiments, the orthographic projection of the first radar sensor 40 may be located outside the orthographic projection range of the steam flow channel 20a but within the orthographic projection range of the food loading / unloading port 11b.
[0107] Here, both the first radar sensor 40 and the second radar sensor 50 are used to acquire cooking parameters such as the fluctuation of food or water surface in the cooking chamber 11a. Thus, the cooking appliance is suitable for cooking two or more kinds of food in one cooking chamber 11a, as well as cooking scenarios where the cooking appliance performs multiple cooking functions such as steaming, boiling, frying, sautéing, and stewing at the same time.
[0108] In some embodiments, the cooking cavity 11a includes a first cooking cavity and a second cooking cavity, projected along the height direction of the cooking appliance, and the detection range of the first radar sensor 40 covers at least a portion of the first cooking cavity, and the detection range of the second radar sensor 50 covers at least a portion of the second cooking cavity.
[0109] Specifically, the orthographic projection of the first radar sensor 40 may be located within the range of the first cooking cavity, and the orthographic projection of the second radar sensor 50 may be located within the range of the orthographic projection of the second cooking cavity.
[0110] Here, a cooking appliance includes two or more inner pots 11. The two inner pots 11 are the first inner pot and the second inner pot.
[0111] The first inner pot has a first cooking cavity, and the second inner pot has a second cooking cavity.
[0112] The first radar sensor 40 is used to regulate the cooking concentration of food in the first cooking cavity, and the second radar sensor 50 is used to regulate the cooking concentration of food in the second cooking cavity.
[0113] The placement of the first radar sensor 40 and the second radar sensor 50 is not restricted.
[0114] For example, please refer to Figure 1 and Figure 2 The first radar sensor 40 and the second radar sensor 50 are both located on the cover assembly 20.
[0115] In this way, the first radar sensor 40 is closer to the steam flow channel 20a, which helps to improve the accuracy of the first radar sensor 40 in obtaining the steam cooking parameters within the steam flow channel 20a.
[0116] The radar signal emitted by the second radar sensor 50 can also enter the cooking chamber 11a through the food loading and unloading port 11b. The food loading and unloading port 11b is a virtual structure that will not interfere with the transmission of the radar signal. This helps to improve the reliability of the second radar sensor 50 in acquiring cooking parameters.
[0117] In some embodiments, please refer to Figure 3 The first radar sensor 40 is located on the cover assembly 20, and the second radar sensor 50 is located on the pot assembly 10.
[0118] Specifically, the second radar sensor 50 can be positioned below the inner pot 11. It should be noted that the heating element of the cooking appliance is usually located below the inner pot 11, and the temperature at the bottom of the cooking cavity 11a is relatively higher. In this embodiment, it is convenient to position the second radar sensor 50 below the cooking cavity 11a, so as to quickly obtain the cooking status of the food located at the bottom of the cooking cavity 11a, thereby obtaining the cooking status of the food more accurately.
[0119] In some embodiments, please refer to Figure 4 and Figure 5 The first radar sensor 40 and the second radar sensor 50 respectively detect cooking parameters at different locations within the cooking cavity 11a.
[0120] Here, both the first radar sensor 40 and the second radar sensor 50 are used to acquire cooking parameters such as the fluctuation of food or water surface in the cooking chamber 11a. Thus, the cooking appliance is suitable for cooking two or more kinds of food in one cooking chamber 11a, as well as cooking scenarios where the cooking appliance performs multiple cooking functions such as steaming, boiling, frying, sautéing, and stewing at the same time.
[0121] In some embodiments, please refer to Figure 3 The multiple radar sensors 30 include a first radar sensor 40 disposed on the lid assembly 20 and a second radar sensor 50 disposed on the pot body assembly 10. The position of the second radar sensor 50 is lower than that of the cooking cavity 11a. When the lid is closed, the orthographic projection of the first radar sensor 40 and the orthographic projection of the second radar sensor 50 are both located within the orthographic projection range of the cooking cavity 11a when projected along the height direction of the cooking appliance.
[0122] Here, the first radar sensor 40 can acquire cooking parameters such as the fluctuation of the food or water surface at the top of the cooking chamber 11a, and the second radar sensor 50 can acquire cooking parameters such as the fluctuation of the food or water surface at the bottom of the cooking chamber 11a. In this way, the cooking parameters from multiple locations within the cooking chamber 11a are superimposed for reference, which helps the cooking appliance to more accurately control the cooking concentration.
[0123] In some embodiments, please refer to Figure 4 and Figure 5 The multiple radar sensors 30 include a first radar sensor 40 and a second radar sensor 50, which are both disposed on the pot body assembly 10, and there is a height difference between the first radar sensor 40 and the second radar sensor 50.
[0124] Here, the first radar sensor 40 and the second radar sensor 50 can respectively acquire cooking parameters at different depths within the cooking cavity 11a.
[0125] For example, when cooking accessories such as steamers and steaming trays are installed in the cooking cavity 11a, the food cooked inside the cooking accessories and the food cooked outside the cooking accessories are at different depths in the cooking cavity 11a. The first radar sensor 40 and the second radar sensor 50 can respectively obtain the cooking parameters at different depths in the cooking cavity 11a. In this way, the cooking appliance can be comprehensively controlled to ensure that the food cooked inside the cooking accessories and the food cooked outside the cooking accessories have a good taste.
[0126] In some embodiments, please refer to Figure 1 and Figure 4 The cooking appliance also includes a control module 60, a radar sensor assembly, and an electrical connection between the control module and the radar sensor assembly. For example, the radar sensor assembly includes multiple radar sensors 30, each of which is electrically connected to the control module 60. Each radar sensor 30 transmits the acquired cooking parameters to the control module 60, which then controls the operation of other components of the cooking appliance (such as the heating unit).
[0127] For example, each radar sensor 30 converts the acquired cooking parameters into electrical signals, which are then transmitted to the control module 60.
[0128] It should be noted that there are no restrictions on the specific way the control module 60 and each radar sensor 30 are electrically connected.
[0129] In some embodiments, the cooking appliance further includes an electrical connection wire, through which the radar sensor assembly is electrically connected to the control module 60. For example, the radar sensor assembly includes a plurality of radar sensors 30 and a plurality of electrical connection wires, with each radar sensor 30 being electrically connected to the control module 60 via one electrical connection wire.
[0130] In this way, the electrical connection between the radar sensor 30 and the control module 60 is more reliable, and the control module 60 can more stably acquire the signal transmitted by the radar sensor 30, thereby achieving more precise control of the cooking concentration, which in turn helps to improve the taste of the food.
[0131] Furthermore, the radar sensor 30 does not require a Wi-Fi module, which helps to reduce the overall size and production cost of the radar sensor 30.
[0132] In other embodiments, the radar sensor assembly is wirelessly connected to the control module 60. For example, the radar sensor assembly includes a plurality of radar sensors 30, each of which is wirelessly connected to the control module 60.
[0133] This makes it easier to achieve electrical connections between the radar sensors 30 and the control module 60. Furthermore, during the production process of the cooking appliance, the wiring steps between the radar sensors 30 and the control module 60 are eliminated, which helps to improve the assembly efficiency of the cooking appliance.
