Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of kitchen utensils, in particular to a cooking device. BACKGROUND
[0002] When cooking food using various types of cookware, a common problem often encountered is the sticking of food to the pot. Especially when cooking with a flat-bottomed soup pot, due to its own structural characteristics, it is not like a frying pan that can be flipped by shaking the pot to evenly heat the food and reduce continuous contact with the bottom of the pot. The proteins and sugars inside the food, under high-temperature cooking conditions, once in close contact with the metal surface of the pot bottom for a long time, the intermolecular forces make them easily adhere to each other. This adhesion not only causes the food to appear as a burnt pot, greatly affecting the taste and quality of the dish, but also makes the subsequent cleaning of the cookware extremely difficult, consuming a large amount of manpower and water resources.
[0003] In the prior art, an anti-sticking coating is provided on the surface of the cookware to solve the problem of sticking. Although this measure alleviates the sticking problem to some extent, its own defects are also quite significant. On the one hand, the service life of the anti-sticking coating is generally limited. As the number of cooking increases and normal wear and tear during daily use, the coating will gradually fall off, losing its anti-sticking effect, forcing consumers to frequently replace the cookware, increasing the cost of living. On the other hand, the coating to some extent blocks the efficient transfer of heat from the bottom of the pot to the food. The cookware with the anti-sticking coating is difficult to achieve the ideal state of heating the food when in use, resulting in an increase in cooking time and energy consumption. More seriously, the non-stick coating usually cannot be cleaned with a steel ball or other rough cleaning tools, otherwise it is easy to cause large-scale damage to the coating, further shortening its service life; and once dry burning occurs, the coating may also decompose harmful substances that mix into the food, unknowingly harming human health and posing a great safety hazard to the user.

[0026] Referring to Figure 1 , Figure 1 The structure of the cooking device 100 in an embodiment of the present application is shown. The cooking device 100 provided by the embodiment of the present application is used to cook food. As shown in Figure 1 The cooking device 100 includes a pot 110, and the pot 110 is provided with a cooking cavity 111 for holding and cooking food. In the present embodiment, the cooking device 100 further includes a pot cover 150 covering the pot 110, and the pot cover 150 covers the opening of the cooking cavity 111 to form a sealed cooking cavity 111, thereby adapting to the cooking needs of different food. In other embodiments, the cooking device 100 can also not include the pot cover 150, at which time the cooking device 100 is suitable for cooking food in the cooking cavity 111 in an open state.
[0027] In combination with Figure 2 As shown, Figure 2A cross-sectional structure schematic diagram of the cooking device 100 in an embodiment of the present application is shown, the pot 110 has a side wall 112 and a bottom surface 113 defining a cooking cavity 111. In one embodiment, the cooking device 100 further comprises a heating member 170 acting on the bottom surface 113, the heating member 170 is used to provide heat for cooking food in the cooking device 100, and the heating member 170 acts on the bottom surface 113 to heat the food in the cooking cavity 111.
[0028] As shown in Figure 1 and Figure 2 , the cooking device 100 further comprises a water level monitoring member 120, the water level monitoring member 120 is connected to the side wall 112 and located in the cooking cavity 111, for monitoring the water level in the cooking cavity 111, and the water level monitoring member 120 is configured to trigger when the water level in the cooking cavity 111 is higher than the position of the water level monitoring member 120.
[0029] As shown in Figure 1 and Figure 2 , the cooking device 100 further comprises a vibration device 130, the vibration device 130 is connected to the pot 110 and acts on the bottom surface 113, the vibration device 130 is used to generate vibration perpendicular to the bottom surface 113, the vibration device 130 is controlled by the water level monitoring member 120, and is configured to be able to adjust the vibration frequency according to whether the water level monitoring member 120 is triggered.
[0030] As shown in Figure 1 and Figure 2 , the cooking device 100 further comprises a base 180, the vibration device 130 is mounted on the base 180 to support the vibration device 130, avoiding displacement of the vibration device 130 when vibrating, etc.
[0031] In the present embodiment, the vibration device 130 is an electromagnetic vibration mechanism, but is not limited. In the present embodiment, the vibration of the vibration device 130 is perpendicular to the bottom surface 113 of the pot 110. During cooking, by starting the vibration device 130, vibration perpendicular to the bottom surface 113 of the pot 110 is generated, which forms a small vortex in the cooking cavity 111 and interacts with the surface of the food. This interaction causes the liquid molecules on the surface of the food to produce shear force and reduce the contact area with the bottom surface 113 of the pot 110, thereby reducing the possibility of adhesion, thereby realizing the effect of reducing the possibility of food adhering to the pot 110 by vibration. On the other hand, vibration can also change the thermal motion inside the food molecules, making the food more evenly heated and improving the cooking effect.
[0032] As shown in Figure 2As shown, in one of the embodiments, the bottom surface 113 is flat, and the pot 110 is exemplarily a flat-bottomed soup pot. Compared with a wok with an arc-shaped bottom for stir-frying, the flat-bottomed soup pot is more likely to cause the food to stick to the bottom surface 113 of the pot 110, but also makes the water level monitoring member 120 more accurate in monitoring the water level in the cooking cavity 111.
[0033] As shown, in one of the embodiments, the vibration device 130 has a vibration frequency when the water level monitoring member 120 is not triggered, which is greater than a vibration frequency when the water level monitoring member 120 is triggered. It can be understood that when the water level monitoring member 120 changes from the triggered state to the untriggered state, it indicates that the water level in the cooking cavity 111 is decreasing, and the possibility of the food in the cooking cavity 111 adhering to the bottom surface 113 of the pot 110 is increasing. At this time, increasing the vibration frequency of the vibration device 130 can improve the effect of vibration and further effectively reduce the possibility of the food adhering to the pot 110. Alternatively, the vibration frequency of the vibration device 130 when the water level monitoring member 120 is not triggered can be zero. Figure 2 As shown, in one of the embodiments, the vibration device 130 has a vibration frequency when the water level monitoring member 120 is not triggered, which is greater than a vibration frequency when the water level monitoring member 120 is triggered. It can be understood that when the water level monitoring member 120 changes from the triggered state to the untriggered state, it indicates that the water level in the cooking cavity 111 is decreasing, and the possibility of the food in the cooking cavity 111 adhering to the bottom surface 113 of the pot 110 is increasing. At this time, increasing the vibration frequency of the vibration device 130 can improve the effect of vibration and further effectively reduce the possibility of the food adhering to the pot 110. Alternatively, the vibration frequency of the vibration device 130 when the water level monitoring member 120 is not triggered can be zero.
[0034] Figure 2 As shown, in one of the embodiments, the number of water level monitoring members 120 is multiple, and all the water level monitoring members 120 are arranged at intervals in height. It can be understood that the higher the water level in the cooking cavity 111, the higher the number of water level monitoring members 120 that are triggered. The vibration device 130 is configured to adjust the vibration frequency according to the number of water level monitoring members 120 that are triggered, so that when the water level in the cooking cavity 111 is in different height intervals, the vibration frequency of the vibration device 130 is also adjusted accordingly. In this embodiment, the number of water level monitoring members 120 is two, and both of the water level monitoring members 120 are connected to the side wall 112 of the pot 110 and arranged at intervals in height.
[0035] In one of the embodiments, the vibration frequency of the vibration device 130 is negatively correlated with the number of water level monitoring members 120 that are triggered. The fewer the number of water level monitoring members 120 that are triggered, the less the water level in the cooking cavity 111, and at this time, the higher the vibration frequency of the vibration device 130, thereby increasing the effect of vibration and further effectively reducing the possibility of the food adhering to the pot 110.
[0036] In one of the embodiments, when all the water level monitoring members 120 are triggered, the vibration device 130 is turned off. When all the water level monitoring members 120 are triggered, the water level in the cooking cavity 111 is higher than the water level monitoring member 120 in the highest position, that is, the water level in the cooking cavity 111 is high at this time, and the possibility of the food sticking to the surface of the pot 110 is small. Therefore, the vibration device 130 can be turned off to save energy.
[0037] As shown, in one of the embodiments, the vibration device 130 has a vibration frequency when the water level monitoring member 120 is not triggered, which is greater than a vibration frequency when the water level monitoring member 120 is triggered. It can be understood that when the water level monitoring member 120 changes from the triggered state to the untriggered state, it indicates that the water level in the cooking cavity 111 is decreasing, and the possibility of the food in the cooking cavity 111 adhering to the bottom surface 113 of the pot 110 is increasing. At this time, increasing the vibration frequency of the vibration device 130 can improve the effect of vibration and further effectively reduce the possibility of the food adhering to the pot 110. Alternatively, the vibration frequency of the vibration device 130 when the water level monitoring member 120 is not triggered can be zero. Figure 2 The illustration shows an embodiment with two water level monitoring elements 120, but this is not a limitation. Optionally, when the water level in the cooking cavity 111 is high, both water level monitoring elements 120 are triggered, and the vibration device 130 can be in the off state. During cooking, as heating continues, the water level in the cooking cavity 111 gradually drops to between the two water level monitoring elements 120. The water level monitoring element 120 at the higher position will change to an off state, but the water level monitoring element 120 at the lower position will remain triggered. At this time, the vibration device 130 is turned on and operates at a low vibration frequency, for example, 100 Hz. As cooking continues, as heating continues, the water level in the cooking cavity 111 gradually drops below the lower water level monitoring element 120, and the lower water level monitoring element 120 will also change to an off state. At this time, the vibration frequency of the vibration device 130 increases, for example, to 500 Hz, thereby increasing the vibration effect and further effectively reducing the possibility of food sticking to the cookware 110.
[0038] like Figure 1 As shown, in one embodiment, the cooking device 100 further includes a temperature monitoring element 140, which is disposed toward the cooking cavity 111 and used to monitor the temperature inside the cooking cavity 111. It is configured to be triggered when the temperature inside the cooking cavity 111 reaches a set temperature. The vibration device 130 is configured to adjust the vibration frequency according to whether the temperature monitoring element 140 is triggered.
[0039] For example, the set temperature is set to the temperature at which food is likely to stick to the surface of the cookware 110. For example, during normal heating, food is usually below 100°C, so the set temperature can be set to 110°C. When the temperature inside the cooking cavity 111 exceeds the set temperature, the possibility or risk of food sticking to the surface of the cookware 110 is higher. By adjusting the vibration frequency of the vibration device 130, the possibility of food sticking to the cookware 110 can be effectively reduced through vibration.
[0040] In one embodiment, the vibration frequency of the vibration device 130 when the temperature monitoring element 140 is triggered is greater than the vibration frequency of the vibration device 130 when the water level monitoring element 120 is not triggered. When the temperature monitoring element 140 is triggered, the vibration frequency of the vibration device 130 is increased, thereby increasing the effect of vibration and further effectively reducing the possibility of food sticking to the cookware 110.
[0041] It is understandable that when there is water remaining in the cooking cavity 111, the temperature inside the cooking cavity 111 will not exceed the actual cooking temperature (e.g., 100°C) by much. When the temperature monitoring device 140 detects that the temperature inside the cooking cavity 111 has reached the set temperature, it is highly likely that the water level monitoring device 120 inside the cooking cavity 111 is in a non-triggered state. At this time, the vibration device 130 is already at a relatively high vibration frequency. When the temperature monitoring device 140 is triggered, it will further increase the vibration frequency of the vibration device 130, for example, to 700Hz.
[0042] like Figure 1 As shown, in one embodiment, a temperature monitoring element 140 is connected to the lid 150 and located on the end face of the lid 150 facing the cooking cavity 111. The temperature monitoring element 140 extends toward the interior of the cooking cavity 111 to monitor the temperature inside the cooking cavity 111. In other embodiments, the temperature monitoring element 140 may also be provided on the side wall 112 of the cookware 110, but this is not a limitation.
[0043] like Figure 1 As shown, in this embodiment, the cooking device 100 also includes a handle 160 located on the outer periphery of the pot 110 to facilitate taking and putting away the pot 110.
[0044] The cooking device 100 provided in the above solution monitors the water level inside the cooking cavity 111 by setting a water level monitoring element 120 on the side wall 112 inside the pot 110 and combining it with a vibration device 130 acting on the pot 110. This allows the device to monitor the water level inside the cooking cavity 111, determine the possibility of food sticking to the pot 110 by the water level, and adjust the vibration frequency of the vibration device 130 according to the water level. During the cooking process, the vibration device 130 continuously adjusts its vibration frequency to flexibly respond to different possibilities of food sticking to the pot 110 inside the cooking cavity 111, thereby effectively reducing the possibility of food sticking to the pot 110 while taking into account energy loss.
[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0046] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
