Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of kitchen utensils, in particular to an inner pot and a cooking appliance. BACKGROUND

[0002] This section is intended to provide background or context to the embodiments described in this application. The description herein does not constitute admission that the information provided herein is prior art.

[0003] When cooking food, an electric rice cooker generally cooks for a fixed time, and the cooking concentration cannot be adjusted. When cooking a small amount of food, the water evaporates a lot, and the cooking concentration is much higher than the fixed concentration; while when cooking a large amount of food, the boiling amount is insufficient, and the concentration is relatively low. Therefore, the taste of the food is poor.

[0004] In related technologies, a radar sensor can be used to detect the cooking state of the food, so as to realize more accurate control of the boiling state and the cooking concentration, thereby improving the taste of the food. In this scheme, the setting position of the radar sensor is particularly important, which needs to ensure that the radar sensor stably detects the cooking state, and also needs to ensure the reliability of the radar sensor. UTILITY MODEL CONTENT

[0005] Therefore, the embodiments of the present application expect to provide an inner pot and a cooking appliance, which are beneficial to improve the taste of food and also beneficial to improve the reliability of the radar sensor.

[0006] To solve the above problems, the technical scheme of the embodiments of the present application is as follows:

[0007] The first aspect of the embodiments of the present application provides an inner pot applied to a cooking appliance, and the inner pot is removably arranged in a containing area of a shell of the cooking appliance, and the inner pot comprises:

[0008] A pot body, an inner wall of which surrounds to form a containing cavity, at least part of the containing cavity is a cooking cavity, and a top side of the cooking cavity is open and forms a food taking and placing opening;

[0009] A radar sensor for detecting the cooking state of food in the cooking cavity;

[0010] A partition wall arranged in the pot body and defining an installation cavity with the pot body, and the radar sensor is arranged in the installation cavity;

[0011] When the pot body is taken out of the containing area of the shell, the radar sensor will be taken out of the containing area together.

[0012] In some embodiments, in the height direction of the cooking appliance, the installation cavity is located below the cooking cavity.

[0013] In some embodiments, the cooking cavity and the mounting cavity are independent of each other in a planar projection parallel to the height direction of the cooking utensil; or,

[0014] In the height direction of the cooking utensil, the bottom wall of the cooking cavity is concave upward to form a groove, and the groove wall and the partition wall together constitute the cavity wall of the mounting cavity.

[0015] In some embodiments, the partition wall is connected to the inner wall of the pot body and separates the containing cavity into the mounting cavity and the cooking cavity.

[0016] In some embodiments, the partition wall is a non-metal wall.

[0017] In some embodiments, the partition wall is connected to the outer wall of the pot body and defines the mounting cavity together with the outer wall of the pot body.

[0018] In some embodiments, at least part of the bottom wall of the pot body is concave toward the food access opening to form a groove, and the partition wall covers the groove and defines the mounting cavity together with the groove wall.

[0019] In some embodiments, the wall of the mounting cavity other than the partition wall is a non-metal wall.

[0020] The second aspect of the embodiments of the present application provides a cooking utensil, comprising:

[0021] A housing is provided with a containing area;

[0022] The inner pot of any one of the above embodiments is arranged in the containing area.

[0023] A cover assembly is used to selectively open or cover the food access opening.

[0024] In some embodiments, the cooking utensil further comprises a control module, which is arranged in the cover assembly or the housing and is wirelessly connected to the radar sensor.

[0025] The inner pot of this embodiment, when applied to a cooking appliance, uses a radar sensor to detect the cooking state of the food inside the cooking cavity. The radar sensor can determine the boiling and non-boiling states at least by observing the water surface fluctuations. This allows for the rapid acquisition of boiling times, enabling more precise control of the cooking concentration and thus improving the food's texture. Simultaneously, the inner pot has an installation cavity for the radar sensor. This installation cavity is independent of the cooking cavity, and the partition wall and the pot body act as a barrier against steam, preventing steam from entering the installation cavity. This mitigates reliability issues such as short circuits caused by direct steam contact with the radar sensor, allowing the radar sensor to reliably and stably detect the cooking state of the food inside the cooking cavity.

[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, this application provides a cooking appliance, please refer to... Figure 1 The cooking appliance includes a pot body assembly 10 and a lid assembly 20.

[0045] Cooking appliances can be, for example, rice cookers, electric pressure cookers, electric slow cookers, etc., and this application does not limit them.

[0046] The pot assembly 10 includes an outer shell 12 and an inner pot 11 according to any embodiment of this application.

[0047] The inner pot 11 has a cooking cavity 11a, the top side of which is open and forms a food loading / unloading port 111b. Food is cooked in the cooking cavity 11a, and the food loading / unloading port 111b 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 2 , Figure 4 or Figure 6 The direction indicated by H in the middle.

[0049] The outer shell 12 has a receiving area, in which at least a portion of the inner pot 11 is disposed, and the inner pot 11 is removably disposed within the receiving area, meaning that the inner pot 11 can be removed from the receiving area. This facilitates cleaning of the cooking cavity 11a by the user.

[0050] The lid assembly 20 is used to selectively open or cover the food opening 111b. Specifically, the lid assembly 20 has an open state and a closed state. In the closed state, the lid assembly 20 covers the food opening 111b; in the open state, the lid assembly 20 opens the food opening 111b.

[0051] For example, when cooking food, the cover assembly 20 is in the closed state and covers the food loading and unloading port 111b, which can effectively improve the problem of hot juice splashing out in the cooking cavity 11a. This makes it safer and easier to clean.

[0052] For example, when the cooking appliance is not in use, the lid assembly 20 is in a closed state and covers the food inlet 111b, thereby effectively reducing the problem of dust and other stains entering the cooking cavity 11a, which is beneficial to health.

[0053] 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 111b is opened, thus facilitating user operation.

[0054] The specific structure used to switch the cover assembly 20 between the open and closed states is not limited.

[0055] In some embodiments, please refer to Figure 1 One side of the lid assembly 20 is rotatably disposed on the pot body assembly 10, and the lid assembly 20 can switch between the open state and the closed state by rotating around this rotating side.

[0056] 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 111b, there is no need to find a temporary place to put the lid assembly 20, which helps to improve the user experience.

[0057] 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.

[0058] Please see Figures 2 to 7 This application embodiment also provides an inner pot, the inner pot 11 including a pot body 111, a radar sensor 30 and a partition wall 112.

[0059] The inner wall of the pot body 111 forms a receiving cavity 111a, at least a portion of which is a cooking cavity 11a. Here, the cooking cavity 11a may constitute the entire space of the receiving cavity 111a, or the cooking cavity 11a may only constitute a part of the space of the receiving cavity 111a.

[0060] The radar sensor 30 is used to detect the cooking status of the food inside the cooking cavity 11a.

[0061] 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.

[0062] The cooking appliance in this embodiment utilizes a radar sensor 30 to detect the cooking state of the food within the cooking chamber 11a. The radar sensor 30 can transmit radar signals to the food within the cooking chamber 11a and receive reflected signals. By detecting frequency changes in the waveform, it detects surface ripples and other phenomena, determining the boiling or non-boiling state based on the surface ripples. This rapid determination of the boiling or non-boiling state enables quick heating and stopping of the cooking process.

[0063] 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.

[0064] 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.

[0065] A partition wall 112 is provided on the pot body 111 and defines a mounting cavity 11b with the pot body 111. The radar sensor 30 is provided in the mounting cavity 11b.

[0066] Here, a connection structure is formed between the partition wall 112 and the pot body 111. That is, if the spatial position of one changes, the other will change accordingly. For example, when the pot body 111 is removed from the receiving area, the partition wall 112 leaves the receiving area along with the pot body 111, and the radar sensor 30 will also leave the receiving area and be removed from the receiving area as well.

[0067] In related technologies, cooking appliances generate a lot of steam during cooking. After the steam leaves the cooking cavity through the food inlet, it can easily come into direct contact with the radar sensor, causing reliability issues such as short circuits in the radar sensor.

[0068] In this embodiment, the mounting cavity 11b is defined by the pot body 111 and the partition wall 112. The radar sensor 30 is disposed in the mounting cavity 11b. The mounting cavity 11b is independent of the cooking cavity 11a. The partition wall 112 and the pot body 111 can form a barrier against steam, making it difficult for steam to enter the mounting cavity 11b. This helps to improve the reliability problem of short circuit of the radar sensor 30 caused by direct contact of steam with the radar sensor 30. The radar sensor 30 can detect the cooking status of the food in the cooking cavity 11a more stably and reliably.

[0069] In summary, the inner pot 11 of this embodiment, when applied to a cooking appliance, uses a radar sensor 30 to detect the cooking state of the food in the cooking chamber 11a. The radar sensor 30 can at least determine the boiling and non-boiling states by observing the water surface fluctuations. This allows for the acquisition of boiling times in a short period, enabling more precise control of the cooking concentration and thus improving the taste of the food. Simultaneously, the inner pot 11 is equipped with a mounting cavity 11b to house the radar sensor 30. The mounting cavity 11b is independent of the cooking chamber 11a, and the partition wall 112 and the pot body 111 act as a barrier against steam, making it difficult for steam to enter the mounting cavity 11b. This helps to mitigate reliability issues such as short circuits caused by direct steam contact with the radar sensor 30, allowing the radar sensor 30 to detect the cooking state of the food in the cooking chamber 11a more stably and reliably.

[0070] It should be noted that the specific location of the mounting cavity 11b on the inner pot 11 is not limited.

[0071] In some embodiments, please refer to Figures 2 to 7 In the height direction of the cooking appliance, the mounting cavity 11b is located below the cooking cavity 11a.

[0072] In other words, the bottom wall of the mounting cavity 11b constitutes at least a portion of the bottom wall of the inner pot 11.

[0073] For example, Figure 2 and Figure 4 In the embodiment, the bottom wall of the mounting cavity 11b constitutes the entire bottom wall of the inner pot 11.

[0074] For example, Figure 6 In the embodiment, the bottom wall of the mounting cavity 11b constitutes part of the bottom wall of the inner pot 11, and the other part of the bottom wall is constituted by the bottom wall of the cooking cavity 11a.

[0075] 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, the radar sensor 30 is located below the cooking cavity 11a, so that the cooking status of the food located at the bottom of the cooking cavity 11a can be obtained more quickly, thus enabling more accurate acquisition of the cooking status of the food.

[0076] The outer wall of the radar sensor 30 includes a signal transmission surface 31, and the radar signal can be transmitted at least along a reference direction; wherein the reference direction is perpendicular to the signal transmission surface 31.

[0077] In some embodiments, in the height direction of the cooking appliance, the mounting cavity 11b is located below the cooking cavity 11a, and the signal transmission surface 31 is not perpendicular to the surface where the food loading / unloading port 111b is located.

[0078] The signal transmission surface 31 is the surface of the wall on the side of the radar sensor 30 facing the cooking cavity 11a. Exemplarily, in... Figure 1 or Figure 2 or Figure 4 or Figure 6 In the embodiment shown, the signal transmission surface 31 is the surface where the top wall of the radar sensor 30 is located.

[0079] 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 111b 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.

[0080] 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 111b is located.

[0081] 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 180°, and the first angle is the smaller angle.

[0082] In this embodiment, it is advantageous that the radar signal emitted by the radar sensor 30 can pass through the wall of the cooking cavity 11a and enter the cooking cavity 11a.

[0083] In some embodiments, the mounting cavity 11b may also be located in the peripheral area of ​​the cooking cavity 11a, so that the radar sensor 30 can also detect the cooking status of the food in the cooking cavity 11a.

[0084] It should be noted that the specific structure of the mounting cavity 11b located below the cooking cavity 11a is not limited.

[0085] In some embodiments, please refer to Figure 2 or Figure 4 The orthographic projections of the cooking cavity 11a and the mounting cavity 11b are independent of each other, projected onto a plane parallel to the height direction of the cooking appliance.

[0086] Here, the cooking cavity 11a and the mounting cavity 11b are stacked along the height direction of the cooking appliance, and the bottom wall of the mounting cavity 11b constitutes the entire bottom wall of the inner pot 11.

[0087] In this embodiment, in the height direction of the cooking appliance, the position of the entire area of ​​the cooking cavity 11a is higher than the position of the signal transmission surface 31 of the radar sensor 30. This makes it easier for the radar sensor 30 to obtain the cooking status of the food at each position in the cooking cavity 11a.

[0088] In some embodiments, please refer to Figure 6 and Figure 7 In the height direction of the cooking appliance, the bottom wall of the cooking cavity 11a is recessed upward to form a groove 111c, and the groove wall of the groove 111c and the partition wall together constitute the cavity wall of the mounting cavity 11b.

[0089] It should be noted that the bottom wall of the cooking cavity 11a can be either the partition wall 112 or the wall of the pot body 111. For example, Figure 6 In the embodiment shown, the bottom wall of the cooking cavity 11a is the wall of the pot body 111.

[0090] In this embodiment, the size of the inner pot 11 can be reasonably controlled along the height direction of the cooking appliance. Furthermore, after the space of the mounting cavity 11b meets the installation requirements of the radar sensor 30, the remaining space occupied by the inner pot 11 can be used more to form the cooking cavity 11a. This is beneficial to increase the space of the cooking cavity 11a, thereby cooking more food.

[0091] In some embodiments, please refer to Figure 4 and Figure 5 The partition wall 112 is connected to the inner wall of the pot body 111 and divides the receiving cavity 111a into the installation cavity 11b and the cooking cavity 11a.

[0092] Here, the partition wall 112 is located in the receiving cavity 111a, part of which is the installation cavity 11b and the other part is the cooking cavity 11a.

[0093] Here, the spacer 112 can be a non-metallic wall. This helps to reduce the interference of the spacer 112 with radar signals.

[0094] The partition wall 112 can be made of glass, ceramic, etc. The partition wall 112 has a certain degree of high temperature resistance.

[0095] It should be noted that the walls of the cooking cavity 11a are generally made of metal. Metal walls have good thermal conductivity, ensuring more even heating of food within the cooking cavity 11a, thus improving the overall taste of the food. The smooth surface of the metal walls makes it difficult for food residue to adhere, facilitating cleaning. The high hardness of the metal walls provides strong wear and corrosion resistance, extending the lifespan of the inner pot 11. Furthermore, the metal walls do not contain harmful substances and will not release toxic gases at high temperatures, making them safer to use.

[0096] Furthermore, after the radar signal enters the cooking cavity 11a, the metal wall can block the radar signal, and the radar signal reflected back to the radar sensor 30 all originates from the cooking cavity 11a. In this way, the parameters acquired by the radar sensor 30 are more accurate, which is conducive to further improving the accuracy of the cooking status of the food detected by the radar sensor 30.

[0097] It is understood that at least a portion of the cavity wall of the cooking cavity 11a is composed of the pot body 111. Therefore, in this embodiment, the pot body 111 can be entirely made of metal. The material of the pot body 111 is relatively uniform, and the molding process is relatively simple. The pot body 111, which is entirely made of metal, has the beneficial effects of the cooking cavity 11a with metal walls. Furthermore, the radar signal does not need to pass through the pot body 111 on the transmission path from the mounting cavity 11b to the cooking cavity 11a. Therefore, the pot body 111, which is entirely made of metal, will not interfere with the transmission of radar signals.

[0098] In some embodiments, please refer to Figure 2 and Figure 3 ,or, Figure 6 and Figure 7 The partition wall 112 is connected to the outer wall of the pot body 111 and defines an installation cavity 11b with the outer wall of the pot body 111.

[0099] Here, the partition wall 112 is located outside the receiving cavity 111a, and the entire space inside the receiving cavity 111a can constitute the cooking cavity 11a.

[0100] Here, the walls of the mounting cavity 11b, except for the spacer wall 112, are non-metallic. That is, the pot body 111 includes non-metallic walls, and the portion of the pot body 111 used to define the mounting cavity 11b is non-metallic. This helps to reduce the interference of the pot body 111 with radar signals.

[0101] It should be noted that the pot body 111 can be entirely made of non-metallic walls; or it can be partially made of metallic walls and partially made of non-metallic walls. Non-metallic walls can be ceramic, glass, etc.

[0102] The mounting cavity 11b and the cooking cavity 11a are separated by the wall of the pot body 111, and the connection between the partition wall 112 and the pot body 111 is located on the outer wall of the pot body 111.

[0103] Compared to the embodiment where the connection between the partition wall 112 and the pot body 111 is located on the inner wall of the pot body 111, in this embodiment, even if there is a gap at the connection between the partition wall 112 and the pot body 111, the cooking chamber 11a and the mounting chamber 11b are still isolated, and the steam or water in the cooking chamber 11a will not enter the mounting chamber 11b, which helps to further improve the reliability of the radar sensor 30.

[0104] The outer wall of the pot body 111 can be its outer outer wall or its outer bottom wall.

[0105] In one specific embodiment, please refer to Figure 6 andFigure 7 At least a portion of the bottom wall of the pot body 111 is recessed toward the food loading / unloading port 111b to form a groove 111c, and a partition wall 112 covers the groove 111c and defines an installation cavity 11b with the groove wall of the groove 111c.

[0106] Here, the outer wall of the pot body 111 is the outer bottom wall of the pot body 111.

[0107] In this embodiment, the inner pot 11 can be of two different sizes along the height direction of the cooking appliance. After the space of the mounting cavity 11b is sufficient for the installation of the radar sensor 30, the remaining space occupied by the inner pot 11 can be used more to form the cooking cavity 11a. This is beneficial to increase the space of the cooking cavity 11a, thereby cooking more food.

[0108] Furthermore, the connection between the partition wall 112 and the pot body 111 is also located on the outer wall of the pot body 111, which helps to further improve the reliability of the radar sensor 30.

[0109] In some embodiments, please refer to Figure 1 The cooking appliance also includes a control module 40, a radar sensor 30, and an electrical connection between the control module 40 and the radar sensor 30.

[0110] The radar sensor 30 transmits the acquired parameters to the control module 40, which in turn controls the operation of other components of the cooking appliance (such as the heating element).

[0111] For example, the radar sensor 30 converts the acquired parameters into electrical signals, which are then transmitted to the control module 40.

[0112] The control module 40 is located on the cover assembly 20 or the housing 12 and is wirelessly connected to the radar sensor 30.

[0113] This facilitates the electrical connection between the radar sensor 30 and the control module 40, and also makes it easier to remove the inner pot 11 from the containing area.

[0114] It should be noted that there is no limit to the number of signal transmission surfaces 31 provided on a radar sensor 30.

[0115] In some embodiments, the 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.

[0116] In other embodiments, please refer to Figure 8 There are multiple signal transmission surfaces 31, and any one of them can receive radar signals and transmit radar signals.

[0117] It should be noted that in the embodiments of this application, "multiple" refers to any number of two or more.

[0118] For example, please refer to Figure 8 The bottom and side walls of the radar sensor 30 are both signal transmission surfaces 31.

[0119] Each signal transmission surface 31 can receive and transmit radar signals. Therefore, any one signal transmission surface 31 can independently detect the cooking status of the food.

[0120] 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.
