Description

Technical Field

[0001] The present invention relates to the technical field of cooking appliances, and in particular, to a cooking utensil, a control method for a cooking utensil, a control device for a cooking utensil, and a readable storage medium. Background Art

[0002] During the cooking process, the heating power of a cooking utensil has a great influence on the cooking effect. Therefore, how to accurately control the heating power of a cooking utensil has become an urgent problem to be solved. Summary of the Invention

[0003] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0004] In view of this, in a first aspect, the present invention provides a cooking utensil, including a housing; a heating member connected to the housing, the heating member being located inside the housing; a detection assembly connected to the heating member or the housing, at least a part of the detection assembly being located inside the housing, the detection assembly being configured to collect the temperature value of a cooking utensil to be cooked and the position parameter of the cooking utensil to be cooked relative to the housing; wherein, the heating power of the heating member is associated with the temperature value and the position parameter.

[0005] The heating member is installed inside the housing, and the heating member can heat the cooking utensil to be cooked, so that the ingredients in the cooking utensil to be cooked can be cooked. The detection assembly is installed on the heating member or the housing. During the cooking process, the detection assembly can detect the temperature and position of the cooking utensil to be cooked, and adjust the heating power of the heating member according to the detected temperature value and position parameter, thereby adjusting the heating fire of the cooking utensil to be cooked.

[0006] In the related art, a cooking utensil only adjusts the heating power of a heating component based on the detected temperature value. During the process of a user stir-frying, due to actions such as stir-frying (vibrating the cooking utensil to be cooked up and down, or causing the cooking utensil to be cooked to move horizontally), lifting the pot (moving the cooking utensil to be cooked up and down), and moving the pot (moving the cooking utensil to be cooked horizontally, with inconsistent contact positions with the cooking utensil to be cooked and changing compression amounts), at this time, the temperature value detected by the cooking utensil may decrease, thereby reducing the heating power of the heating component. However, during the processes of stir-frying, lifting the pot, and moving the pot, high heating power is often required for cooking, which contradicts the control of the heating component by the cooking utensil, thus affecting the cooking effect.

[0007] In the present invention, the detection assembly not only detects the temperature value of the cooking utensil to be cooked, but also detects the position parameter of the cooking utensil to be cooked. It can identify whether the user is currently performing a stir-frying action according to the position of the cooking utensil to be cooked relative to the housing, and then can adjust the heating power of the heating member accordingly, avoiding the situation of reduced heating power during the stir-frying process, which is beneficial to improving the cooking effect of the cooking utensil.

[0008] In addition, the cooking appliance according to the above technical solution provided by the present invention may further have the following additional technical features:

[0009] In some technical solutions, optionally, the detection component includes: an elastic member, a first end of the elastic member is connected to the heating member or the housing; a detection member, connected to a second end of the elastic member, the detection member is configured to collect a temperature value and a position parameter, a detection hole is provided on the housing, and a part of the detection member extends out of the detection hole.

[0010] The detection member is configured to detect the temperature and position of the cooking utensil to be cooked. A detection hole is formed on the housing, and a part of the detection member passes through the detection hole. Therefore, a part of the detection member is located inside the housing, and another part of the detection member extends out of the housing. The part of the detection member extending out of the housing can contact the cooking utensil to be cooked, thereby improving the detection accuracy of the temperature value and the position parameter, further improving the adjustment accuracy of the heating power of the heating member, and thus being beneficial to improving the cooking effect of the cooking appliance.

[0011] An elastic member is formed on the heating member or the housing, and the elastic member is connected to the detection member. When the cooking utensil to be cooked contacts the detection member, the cooking utensil can push the detection member, causing the detection member to move into the housing and compress the elastic member. The elastic member plays a buffering role for the detection member, avoiding rigid contact between the cooking utensil and the detection member, thereby reducing the damage rate of the detection member and preventing the detection member from interfering with the use of the cooking utensil.

[0012] When the cooking utensil to be cooked is lifted relative to the housing, the elastic member can push the detection member to extend out of the housing, so that the detection member is in stable contact with the cooking utensil to be cooked, further improving the detection accuracy of the temperature value and the position parameter.

[0013] In some technical solutions, optionally, the cooking appliance further includes: a limiting portion, connected to the heating member, the limiting portion is configured to limit the detection member to limit the maximum length that the detection member can extend out of the housing.

[0014] The detection component is configured to detect the temperature and position of the cooking utensil to be cooked. Therefore, the detection component is usually installed at the central position of the housing. So a part of the detection component will pass through the heating member. At this time, a part of the detection component can be installed on the heating member, which is beneficial to improving the installation convenience of the detection component.

[0015] Since a part of the detection component passes through the heating element, a limiting portion can be formed by machining on the heating element, and the limiting portion is used to limit the detection component. The elastic member applies a pushing force to the detection component towards the outside of the housing. By limiting the detection component with the limiting portion, the limit position of the detection component moving towards the outside of the housing can be restricted, thereby preventing the detection component from completely protruding from the housing and ensuring the installation stability of the detection component. Moreover, by restricting the maximum length that the detection component can protrude from the housing with the limiting portion, it is possible to prevent the length of the detection component protruding from the housing from being too large, thereby avoiding the detection component from being knocked and damaged.

[0016] Of course, in other embodiments, the limiting portion can also be formed by machining on the housing.

[0017] In some technical solutions, optionally, when the detection component contacts the limiting portion, the elastic member is in a deformed state.

[0018] When the detection component contacts the limiting portion, the limiting portion limits the detection component. At this time, the detection component cannot continue to move towards the outside of the housing. As the elastic member pushes the detection component towards the outside of the housing, the deformation amount of the elastic member gradually decreases. When the detection component contacts the limiting portion, the elastic member is in a deformed state, that is, at this time, the elastic member still has a deformation amount.

[0019] When the detection component is limited by the limiting portion, the elastic member has a pushing force on the detection component, preventing the detection component from shaking relative to the housing and ensuring the contact stability between the detection component and the cooking utensil to be cooked.

[0020] In some technical solutions, optionally, the detection component includes: a housing; a temperature detection element connected to the housing, and the temperature detection element is used to collect temperature values; a force detection element, one end of the force detection element is connected to the elastic member, and the other end of the force detection element is connected to the housing, and the force detection element is used to collect position parameters.

[0021] The force detection element is connected to the elastic member and also contacts the housing. When the elastic member pushes the force detection element, the force detection element will push the housing. The temperature detection element is installed on the housing. Therefore, under the push of the elastic member, the force detection element, the housing and the temperature detection element will move towards the outside of the housing together.

[0022] The temperature detection element is located on the top wall of the housing, so that the temperature detection element can accurately detect the temperature value of the cooking utensil to be cooked.

[0023] The force detection element is arranged between the housing and the elastic member. When the cooking vessel to be cooked contacts the housing, the acting force of the cooking vessel on the housing will be transmitted to the force detection element, so that the force detection element can detect the acting force exerted by the cooking vessel on the housing. During the user's stir-frying process, as the cooking vessel to be cooked vibrates and moves up and down, the pressure value detected by the force detection element will change. Therefore, it is possible to determine whether stir-frying cooking is currently being carried out based on the change in the pressure value, so that the firepower can be increased during stir-frying to meet the cooking requirements of high-fire stir-frying, which is beneficial to improving the cooking effect of the cooking appliance.

[0024] In this embodiment, the pressure value detected by the force detection element is the position parameter of the cooking vessel to be cooked. Of course, in other embodiments, a distance sensor can also be used to detect the position of the cooking vessel to be cooked, that is, the distance value is the position parameter of the cooking vessel to be cooked.

[0025] In some technical solutions, optionally, the housing includes: a cover body, the temperature detection element and the force detection element are located inside the cover body, and a part of the cover body is in contact with the limiting part; a positioning member, connected to the cover body, and the force detection element and the elastic member are sleeved on the positioning member.

[0026] Both the temperature detection element and the force detection element are installed inside the cover body, and the cover body plays a protective role for the temperature detection element and the force detection element, which is beneficial to reducing the damage rate of the temperature detection element and the force detection element.

[0027] A positioning member is provided on the cover body. The positioning member in this embodiment is a cylindrical structure, and both the force detection element and the elastic member are sleeved on the positioning member, avoiding the force detection element and the elastic member from deviating from the installation position, ensuring the accuracy of the force detection element in collecting the position parameter, and ensuring the effective buffering of the elastic member for the detection member.

[0028] In some technical solutions, optionally, the housing includes a top wall, a detection hole is provided on the top wall, and there is a gap between the top wall and the heating element; the cooking appliance further includes: a sealing member, located in the gap, and the sealing member is used to seal the gap between the top wall and the heating element.

[0029] A detection hole is machined and formed on the top wall of the housing, so that the detection member can pass through the detection hole and extend out of the top wall of the housing. During the cooking process, the cooking vessel to be cooked needs to be placed on the top wall, so that the detection member can collect the temperature value and position parameter of the cooking vessel to be cooked.

[0030] The detection element can be extended and retracted relative to the detection hole, so there is a gap between the inner wall of the detection hole and the detection element, and the water during cooking can pass through the detection hole into the shell. A seal is installed between the top wall and the heating element, and the seal seals the gap between the top wall and the heating element to prevent the water from contacting the heating components on the heating element, thereby avoiding leakage and short circuit problems, which is conducive to improving the safety of cooking utensils.

[0031] In some technical solutions, optionally, a receiving portion and a first water leakage hole are provided on the heating element, a part of the detection component is located in the receiving portion, and the first water leakage hole is connected to the receiving portion.

[0032] The heating element is formed with a receiving portion, which is used to receive the detection component. For example, the elastic element and the housing are received in the receiving portion. The receiving portion avoids a part of the detection component, so that the detection component does not occupy too much space in the thickness direction of the cooking utensil, which is beneficial to improve the space utilization rate inside the cooking utensil and reduce the overall size of the cooking utensil.

[0033] Since part of the detection component is located in the accommodating part, the water in the cooking process passes through the detection hole and enters the accommodating part. A first water leakage hole is provided at the bottom of the accommodating part, and the water entering the accommodating part can be discharged through the first water leakage hole, thereby avoiding water accumulation in the accommodating part, preventing water from contacting the heating element for a long time, and reducing the damage rate of the heating element.

[0034] In some technical solutions, optionally, the shell is provided with an inner cavity and a second water leakage hole, the heating element is located in the inner cavity, and the second water leakage hole is connected to the inner cavity.

[0035] The shell is provided with an inner cavity, a part of the detection component and the heating element are located in the inner cavity, and a second water leakage hole is opened at the bottom of the inner cavity. The water passing through the first water leakage hole flows to the bottom of the heating element, and the water can be discharged from the shell through the second water leakage hole, so as to avoid the accumulation of water in the shell, avoid the shell being in a humid state for a long time, and reduce the damage rate of the electrical components in the shell.

[0036] In some technical solutions, optionally, a portion of the detection component extends out of the housing, and the length of the detection component extending out of the housing is L, which satisfies 0mm<L≤30mm.

[0037] To ensure that the detection component can accurately collect the temperature value and position parameters, a part of the detection component needs to extend out of the housing. If the length of the detection component extending out of the housing is excessive, for example, when the length of the detection component extending out of the housing is greater than 30 mm, the length of the detection component extending out of the housing is too large, which will cause interference between the detection component and the cooking utensil to be cooked, thus bringing inconvenience to the user. In this embodiment, it is defined that a part of the detection component extends out of the housing, and the length extending out of the housing is less than or equal to 30 mm, so as to avoid bringing inconvenience to the user while ensuring the accuracy of the information collected by the detection component.

[0038] In a second aspect, the present invention proposes a control method for a cooking appliance, which is used for the cooking appliance as in the first aspect. The control method includes: collecting the temperature value of the cooking utensil to be cooked and the position parameter of the cooking utensil to be cooked relative to the housing; determining the heating power of the heating element according to the temperature value and the position parameter; and controlling the operation of the heating element according to the heating power.

[0039] The heating element is installed in the housing, and the heating element can heat the cooking utensil to be cooked, so that the food in the cooking utensil can be cooked. The detection component is installed on the heating element or the housing. During the cooking process, the detection component can detect the temperature and position of the cooking utensil to be cooked, and adjust the heating power of the heating element according to the detected temperature value and position parameter, so as to adjust the heating firepower of the cooking utensil to be cooked.

[0040] In the related art, the cooking appliance only adjusts the firepower of the heating component according to the detected temperature value. During the process of the user stir-frying, due to actions such as stir-frying (vibrating the cooking utensil to be cooked up and down, or causing the cooking utensil to move horizontally), lifting the pot (moving the cooking utensil to be cooked up and down), and moving the pot (moving the cooking utensil to be cooked horizontally, with inconsistent contact positions with the cooking utensil to be cooked and changing the compression amount), at this time, the temperature value detected by the cooking appliance may decrease, thereby reducing the firepower of the heating component. However, during the processes of stir-frying, lifting the pot and moving the pot, high firepower is often required for cooking, which is contradictory to the control of the heating component by the cooking appliance, thus affecting the cooking effect.

[0041] In the present invention, the detection component not only detects the temperature value of the cooking utensil to be cooked, but also detects the position parameter of the cooking utensil to be cooked. It can identify whether the user is currently performing a stir-frying action according to the position of the cooking utensil to be cooked relative to the housing, and then can adjust the firepower of the heating element accordingly, avoiding the situation of reduced firepower during the stir-frying process, which is beneficial to improving the cooking effect of the cooking appliance.

[0042] In some technical solutions, optionally, position parameters of the cooking utensil relative to the housing are collected, including: collecting N position parameters within a set time period; determining the heating power of the heating element according to the temperature value and the position parameters, including: determining the position parameter fluctuation value according to the N position parameters; increasing the heating power of the heating element based on the position parameter fluctuation value being greater than the set value; and determining the heating power of the heating element according to the temperature value based on the position parameter fluctuation value being less than or equal to the set value.

[0043] During the cooking process, it is necessary to collect N position parameters within a set time period. For example, 120 position parameters are collected within 120 seconds. The collected N position parameters are processed to obtain the position parameter fluctuation value. The position parameter fluctuation value is used to reflect the fluctuation of the N position parameters within the set time. If the position parameter fluctuation value is greater than the set value, it indicates that the fluctuation of the N position parameters is large. At this time, the user is cooking by stir-frying, and the demand for high-fire cooking can be met by increasing the heating power of the heating element. If the position parameter fluctuation value is less than or equal to the set value, it indicates that the fluctuation of the N position parameters is small. At this time, the position change of the cooking utensil is small, and the heating power of the heating element can be controlled according to the temperature value of the cooking utensil. For example, when the temperature of the cooking utensil is low, the heating power of the heating element is increased, and when the temperature of the cooking utensil is high, the heating power of the heating element is decreased. Controlling the heating power of the heating element through the temperature value and the position parameters is beneficial to improving the cooking effect of the cooking appliance.

[0044] In a third aspect, the present invention provides a control device for a cooking appliance, which is used for the cooking appliance in the first aspect. The control device includes: a collection module that collects the temperature value of the cooking utensil and the position parameters of the cooking utensil relative to the housing; a determination module that determines the heating power of the heating element according to the temperature value and the position parameters; and a control module that controls the operation of the heating element according to the heating power.

[0045] The heating element is installed in the housing and can heat the cooking utensil, so that the ingredients in the cooking utensil can be cooked. The detection component is installed on the heating element or the housing. During the cooking process, the detection component can detect the temperature and position of the cooking utensil, and adjust the heating power of the heating element according to the detected temperature value and position parameters, so as to adjust the heating firepower of the cooking utensil.

[0046] In the related art, the cooking appliance adjusts the firepower of the heating component only by the detected temperature value. During the cooking process, due to the actions of stir-frying (vibrating the cooking vessel up and down, or causing the cooking vessel to move in plane), lifting the pot (moving the cooking vessel up and down), and moving the pot (moving the cooking vessel in plane, inconsistent with the contact position of the cooking vessel, and changes in compression), the temperature value detected by the cooking appliance may decrease, thereby reducing the firepower of the heating component. However, in the process of stir-frying, lifting the pot and moving the pot, high firepower is often required for cooking, which conflicts with the control of the heating component by the cooking appliance, thus affecting the cooking effect.

[0047] In the present invention, the detection component detects both the temperature value of the cooking vessel and the position parameter of the cooking vessel. It can identify whether the user is currently performing a cooking action based on the position of the cooking vessel relative to the shell, and then the firepower of the heating element can be adjusted in a targeted manner to avoid the situation where the firepower is reduced during the cooking process, which is beneficial to improving the cooking effect of the cooking appliance.

[0048] In some technical solutions, optionally, the acquisition module is specifically used to: collect N position parameters within a set time; the determination module is specifically used to: determine the position parameter fluctuation value based on the N position parameters; increase the heating power of the heating element based on the position parameter fluctuation value being greater than the set value; determine the heating power of the heating element based on the temperature value based on the position parameter fluctuation value being less than or equal to the set value.

[0049] During the cooking process, it is necessary to collect N position parameters within a set time period, for example, collect 120 times within 120 seconds, process the collected N position parameters, and obtain the position parameter fluctuation value. The position parameter fluctuation value is used to reflect the fluctuation of the N position parameters within the set time. If the position parameter fluctuation value is greater than the set value, it means that the fluctuation of the N position parameters is large. At this time, the user is performing stir-fry cooking. The demand for high-power cooking can be met by increasing the heating power of the heating element. If the position parameter fluctuation value is less than or equal to the set value, it means that the fluctuation of the N position parameters is small. At this time, the position change of the cooking vessel is small. The heating power of the heating element can be controlled according to the temperature value of the cooking vessel. For example, when the temperature of the cooking vessel is low, the heating power of the heating element is increased, and when the temperature of the cooking vessel is high, the heating power of the heating element is reduced. Controlling the heating power of the heating element by temperature value and position parameter is conducive to improving the cooking effect of the cooking utensils.

[0050] In a fourth aspect, the present invention provides a control device for a cooking appliance, comprising a memory and a processor, wherein the memory stores a program or instruction that can be run on the processor, and when the program or instruction is executed by the processor, the steps of the control method for the cooking appliance in the second aspect are implemented.

[0051] In a fifth aspect, the present invention provides a readable storage medium having a program or instructions stored thereon, and when the program or instructions are executed by a processor, the steps of the control method of the cooking appliance in the second aspect are implemented.

Detailed implementation manners

[0068] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0069] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0070] Next, refer to Figures 1 to 12 Describe a cooking appliance, a control method of the cooking appliance, a control device of the cooking appliance, and a readable storage medium provided according to some embodiments of the present invention.

[0071] As Figure 1 shown, in an embodiment of the present invention, a cooking appliance is proposed, including a housing 110, a heating element 120, and a detection assembly 130. The heating element 120 is connected to the housing 110, and the heating element 120 is located inside the housing 110. The detection assembly 130 is connected to the heating element 120 or the housing 110, at least a part of the detection assembly 130 is located inside the housing 110, the detection assembly 130 is used to collect the temperature value of the cooking utensil 150 to be cooked and the position parameter of the cooking utensil 150 relative to the housing 110, and the heating power of the heating element 120 is associated with the temperature value and the position parameter.

[0072] The heating element 120 is installed inside the housing 110. The heating element 120 can heat the cooking vessel 150 to cook the food ingredients in the cooking vessel 150. The detection component 130 is installed on the heating element 120 or the housing 110. During the cooking process, the detection component 130 can detect the temperature and position of the cooking vessel 150, and adjust the heating power of the heating element 120 according to the detected temperature value and position parameter, so as to adjust the heating firepower of the cooking vessel 150.

[0073] In the related art, the cooking appliance only adjusts the firepower of the heating component according to the detected temperature value. During the user's stir-frying process, due to actions such as stir-frying (vibrating the cooking vessel 150 up and down, or causing the cooking vessel 150 to move horizontally), lifting the pot (moving the cooking vessel 150 up and down), and moving the pot (moving the cooking vessel 150 horizontally, with inconsistent contact positions with the cooking vessel 150 and changing compression amounts), the temperature value detected by the cooking appliance may decrease at this time, thereby reducing the firepower of the heating component. However, during the stir-frying, pot-lifting, and pot-moving processes, high firepower is often required for cooking, which contradicts the control of the heating component by the cooking appliance, thus affecting the cooking effect.

[0074] In the present invention, the detection component 130 not only detects the temperature value of the cooking vessel 150 but also detects the position parameter of the cooking vessel 150. It can identify whether the user is currently performing a stir-frying action according to the position of the cooking vessel 150 relative to the housing 110, and then can adjust the firepower of the heating element 120 accordingly, avoiding the situation of reduced firepower during the stir-frying process, which is beneficial to improving the cooking effect of the cooking appliance.

[0075] The cooking appliance further includes: a blower 160, a power cord 170, a power board 180, and a control board 190. The blower 160 is installed inside the housing 110. The power cord 170 is electrically connected to the power board 180. The power board 180 and the control board 190 are installed inside the housing 110.

[0076] The cooking appliance can be an induction cooker, an electric baking pan, a hot plate, etc.

[0077] In some embodiments, optionally, the detection component 130 includes: an elastic member 131 and a detection member 132. The first end of the elastic member 131 is connected to the heating element 120 or the housing 110. The detection member 132 is connected to the second end of the elastic member 131. The detection member 132 is used to collect the temperature value and position parameter. A detection hole 112 is provided on the housing 110, and a part of the detection member 132 extends out of the detection hole 112.

[0078] The detection member 132 is used to detect the temperature and position of the cooking utensil 150 to be cooked. A detection hole 112 is formed in the housing 110 by machining. A part of the detection member 132 passes through the detection hole 112. Therefore, a part of the detection member 132 is located inside the housing 110, and the other part of the detection member 132 extends out of the housing 110. The part of the detection member 132 extending out of the housing 110 can contact the cooking utensil 150 to be cooked, thereby improving the detection accuracy of the temperature value and position parameters, further improving the adjustment accuracy of the heating power of the heating member 120, and thus being beneficial to improving the cooking effect of the cooking appliance.

[0079] An elastic member 131 is formed by machining on the heating member 120 or the housing 110. The elastic member 131 is connected to the detection member 132. When the cooking utensil 150 to be cooked contacts the detection member 132, the cooking utensil 150 can push the detection member 132, causing the detection member 132 to move into the housing 110 and compress the elastic member 131. The elastic member 131 plays a buffering role for the detection member 132, avoiding rigid contact between the cooking utensil 150 and the detection member 132, thereby reducing the damage rate of the detection member 132 and preventing the detection member 132 from interfering with the use of the cooking utensil 150.

[0080] When the cooking utensil 150 to be cooked is lifted relative to the housing 110, the elastic member 131 can push the detection member 132 to extend out of the housing 110, so that the detection member 132 is in stable contact with the cooking utensil 150, further improving the detection accuracy of the temperature value and position parameters.

[0081] Exemplarily, the elastic member 131 is a spring piece, a spring, etc.

[0082] Combined Figure 1 、 Figure 2 and Figure 3 As shown in [relevant figures], in some embodiments, optionally, the cooking appliance further includes: a limiting portion 121, the limiting portion 121 is connected to the heating member 120, and the limiting portion 121 is used to limit the detection member 132 to limit the maximum length that the detection member 132 can extend out of the housing 110.

[0083] The detection assembly 130 is used to detect the temperature and position of the cooking utensil 150 to be cooked. Therefore, the detection assembly 130 is usually installed at the central position of the housing 110. So a part of the detection assembly 130 will pass through the heating member 120. At this time, a part of the detection assembly 130 can be installed on the heating member 120, which is beneficial to improving the installation convenience of the detection assembly 130.

[0084] Since a part of the detection component 130 passes through the heating component 120, a limiting part 121 can be formed on the heating component 120 by machining. The limiting part 121 is used to limit the detection part 132. The elastic part 131 applies a driving force to the detection part 132 towards the outside of the housing 110. By limiting the detection part 132 with the limiting part 121, the limit position of the detection part 132 moving towards the outside of the housing 110 can be restricted, thereby preventing the detection part 132 from completely protruding out of the housing 110 and ensuring the installation stability of the detection part 132. Moreover, by restricting the maximum length that the detection part 132 can protrude out of the housing 110 with the limiting part 121, it is possible to prevent the length of the detection part 132 protruding out of the housing 110 from being too large, thereby avoiding the detection part 132 from being knocked and damaged.

[0085] In this embodiment, the limiting part 121 and the heating component 120 are of an integrally formed structure. In other embodiments, a limiting part 121 can also be separately locked on the heating component 120.

[0086] Of course, in other embodiments, the limiting part 121 can also be formed on the housing 110 by machining.

[0087] As Figure 2 shown, in some embodiments, optionally, when the detection part 132 contacts the limiting part 121, the elastic part 131 is in a deformed state.

[0088] When the detection part 132 contacts the limiting part 121, the limiting part 121 limits the detection part 132. At this time, the detection part 132 cannot continue to move towards the outside of the housing 110. As the elastic part 131 pushes the detection part 132 towards the outside of the housing 110, the deformation amount of the elastic part 131 gradually decreases. When the detection part 132 contacts the limiting part 121, the elastic part 131 is in a deformed state, that is, at this time, the elastic part 131 still has a deformation amount.

[0089] When the detection part 132 is limited by the limiting part 121, the elastic part 131 has a driving force on the detection part 132, preventing the detection part 132 from shaking relative to the housing 110 and ensuring the contact stability between the detection part 132 and the cooking utensil 150 to be cooked.

[0090] Combined Figure 2 、 Figure 3 and Figure 4 shown, in some embodiments, optionally, the detection part 132 includes: a housing 133, a temperature detection element 134, and a force detection element 135. The temperature detection element 134 is connected to the housing 133. The temperature detection element 134 is used to collect temperature values. One end of the force detection element 135 is connected to the elastic part 131, and the other end of the force detection element 135 is connected to the housing 133. The force detection element 135 is used to collect position parameters.

[0091] The force detection element 135 is connected to the elastic member 131 and also contacts the housing 133. When the elastic member 131 pushes the force detection element 135, the force detection element 135 will push the housing 133. The temperature detection element 134 is installed on the housing 133. Therefore, under the push of the elastic member 131, the force detection element 135, the housing 133, and the temperature detection element 134 will move out of the housing 110 together.

[0092] The temperature detection element 134 is located on the top wall 111 of the housing 133, enabling the temperature detection element 134 to accurately detect the temperature value of the cooking vessel 150 to be cooked.

[0093] The force detection element 135 is arranged between the housing 133 and the elastic member 131. When the cooking vessel 150 contacts the housing 133, the acting force of the cooking vessel 150 on the housing 133 will be transmitted to the force detection element 135, enabling the force detection element 135 to detect the acting force exerted by the cooking vessel 150 on the housing 133. During the user's stir-frying process, as the cooking vessel 150 vibrates and moves up and down, the pressure value detected by the force detection element 135 will change. Therefore, it is possible to determine whether stir-frying is currently being performed based on the change in the pressure value, so that the firepower can be increased during stir-frying to meet the cooking requirements of high-fire stir-frying, which is conducive to improving the cooking effect of the cooking appliance.

[0094] Combined Figure 6 and Figure 7 As shown, the cooking vessel 150 can be a cookware. Taking the cookware pre-deformed into a concave shape as an example: during the process of the temperature of the cookware rising, the concavity intensifies, resulting in an increase in the size of the part of the detection assembly 130 passing through the detection hole 112, that is, a decrease in the compression amount of the elastic member 131 in the detection assembly 130 and a decrease in the elastic force, so that the force sampling value of the force detection element 135 gradually decreases. Due to the different vertical distances between each position of the bottom of the pot and the top of the housing 110, in different scenarios, the change trends of the force sampling values of the force sensors vary greatly, as follows:

[0095] As Figure 8 shown, when the user is in scenarios such as boiling water, cooking soup, or frying oil, since the cookware usually does not require large operations or even any operations after being placed. Therefore, the values of the temperature detection element 134 and the force detection element 135 change smoothly.

[0096] Figure 8 In, the abscissa is time t, whose unit can be seconds or minutes, and the ordinate is the sampling value A. When A represents the temperature value, the unit of the sampling value A is °C, and when A represents the force sampling value, the unit of the sampling value A is N.

[0097] As Figure 9As shown, during the stir-frying process, due to actions such as stir-frying, lifting the pot, and moving the pot, the size of the detection component 130 passing through the detection hole 112 changes frequently, causing the sampling value of the force detection element 135 to fluctuate significantly up and down. In the program, by recognizing this fluctuation, it is determined that the user is stir-frying. At this time, the influence of temperature is ignored, and the heating power of the heating element 120 is increased. When the sampling value of the force detection element 135 gradually stabilizes, the firepower is controlled according to the temperature value.

[0098] Figure 9 In it, the abscissa is time t, whose unit can be seconds or minutes, and the ordinate is the sampling value A. When A represents the temperature value, the unit of the sampling value A is °C, and when A represents the force sampling value, the unit of the sampling value A is N.

[0099] In this embodiment, the pressure value detected by the force detection element 135 is the position parameter of the cooking vessel 150. Of course, in other embodiments, a distance sensor can also be used to detect the position of the cooking vessel 150, that is, the distance value is the position parameter of the cooking vessel 150.

[0100] Exemplarily, the cooking appliance in this embodiment is an induction cooker, and the heating element 120 is a coil assembly 122. The coil assembly 122 includes a coil 122 and a coil 123. The limiting portion 121 is provided on the coil 122, and a convex structure is provided on the circumferential direction of the housing 133, and the convex structure fits with the limiting portion 121.

[0101] Exemplarily, the temperature detection element 134 is a temperature sensor.

[0102] As Figure 5 shown, in some embodiments, optionally, the housing 133 includes: a cover body 136 and a positioning member 137. The temperature detection element 134 and the force detection element 135 are located inside the cover body 136. A part of the cover body 136 is in contact with the limiting portion 121. The positioning member 137 is connected to the cover body 136. The force detection element 135 and the elastic member 131 are sleeved on the positioning member 137.

[0103] Both the temperature detection element 134 and the force detection element 135 are installed inside the cover body 136. The cover body 136 plays a protective role for the temperature detection element 134 and the force detection element 135, which is beneficial to reducing the damage rate of the temperature detection element 134 and the force detection element 135.

[0104] The cover body 136 is provided with a positioning member 137. The positioning member 137 in this embodiment is a cylindrical structure. Both the force detection element 135 and the elastic member 131 are sleeved on the positioning member 137, avoiding the force detection element 135 and the elastic member 131 from deviating from the installation position, ensuring the accuracy of the force detection element 135 in collecting the position parameter, and ensuring the effective buffering of the elastic member 131 to the detection member 132.

[0105] In a possible application, the cover 136 and the positioning member 137 are integrally formed structures.

[0106] In a possible application, the cover 136 includes a base 138 and a cap 139. The cap 139 and the base 138 are connected by a snap connection, and the temperature detection element 134 is located between the cap 139 and the base 138.

[0107] Combined Figure 2 and Figure 3 As shown, in some embodiments, optionally, the housing 110 includes a top wall 111. A detection hole 112 is provided on the top wall 111, and there is a gap between the top wall 111 and the heating element 120. The cooking appliance further includes: a seal 140. The seal 140 is located in the gap and is used to seal the gap between the top wall 111 and the heating element 120.

[0108] The detection hole 112 is machined and formed between the top walls 111 of the housing 110, so that the detection member 132 can pass through the detection hole 112 and extend out of the top wall 111 of the housing 110. During cooking, the cooking utensil 150 to be cooked needs to be placed on the top wall 111, so that the detection member 132 can collect the temperature value and position parameters of the cooking utensil 150 to be cooked.

[0109] The detection member 132 can telescopically move relative to the detection hole 112. Therefore, there is a gap between the inner wall of the detection hole 112 and the detection member 132, and the water during cooking can pass through the detection hole 112 and enter the housing 110. The seal 140 is installed between the top wall 111 and the heating element 120. The seal 140 seals the gap between the top wall 111 and the heating element 120, preventing the water from contacting the heating components on the heating element 120, thus avoiding problems such as electric leakage and open circuit, which is beneficial to improving the use safety of the cooking appliance.

[0110] Exemplarily, the seal 140 is a sealing rubber ring. A fitting portion is provided on the heating element 120 or the housing 110, and a fitting groove is provided on the sealing rubber ring. The fitting portion is embedded into the fitting groove to ensure the installation stability of the sealing rubber ring.

[0111] As Figure 2 shown, in some embodiments, optionally, the heating element 120 is provided with a receiving portion 124 and a first water leakage hole 125. A part of the detection assembly 130 is located in the receiving portion 124, and the first water leakage hole 125 is communicated with the receiving portion 124.

[0112] The heating element 120 is formed with a receiving portion 124, which is used to receive the detection component 130. For example, the elastic member 131 and the housing 133 are received in the receiving portion 124. The receiving portion 124 avoids a part of the detection component 130, so that the detection component 130 does not occupy too much space in the thickness direction of the cooking appliance, which is beneficial to improving the space utilization rate inside the cooking appliance and reducing the overall size of the cooking appliance.

[0113] Since part of the detection assembly 130 is located in the accommodating portion 124, the water in the cooking process passes through the detection hole 112 and enters the accommodating portion 124. A first water leakage hole 125 is provided at the bottom of the accommodating portion 124. The water entering the accommodating portion 124 can be discharged through the first water leakage hole 125, thereby avoiding the accumulation of water in the accommodating portion 124, preventing the water from contacting the heating element 120 for a long time, and reducing the damage rate of the heating element 120.

[0114] Combination Figure 1 and Figure 2 As shown, in some embodiments, optionally, the housing 110 is provided with an inner cavity 113 and a second water leakage hole 114, the heating element 120 is located in the inner cavity 113, and the second water leakage hole 114 is connected to the inner cavity 113.

[0115] The housing 110 is provided with an inner cavity 113, a part of the detection component 130 and the heating element 120 are located in the inner cavity 113, and a second water leakage hole 114 is opened at the bottom of the inner cavity 113. The water passing through the first water leakage hole 125 flows to the bottom of the heating element 120, and the water can be discharged from the housing 110 through the second water leakage hole 114, so as to avoid the accumulation of water in the housing 110, avoid the housing 110 being in a humid state for a long time, and reduce the damage rate of the electrical components in the housing 110.

[0116] In some embodiments, optionally, a portion of the detection component 130 extends out of the housing 110, and the length of the detection component 130 extending out of the housing 110 is L, which satisfies 0mm<L≤30mm.

[0117] In order to ensure that the detection component 130 can accurately collect temperature values ​​and position parameters, it is necessary to extend a portion of the detection component 130 out of the housing 110. If the detection component 130 extends out of the housing 110 by too much, for example, if the length of the detection component 130 extending out of the housing 110 is greater than 30 mm, the detection component 130 extending out of the housing 110 by too much will cause interference between the detection component 130 and the cooking vessel 150, thereby causing inconvenience to the user. In this embodiment, it is limited that a portion of the detection component 130 extends out of the housing 110, and the length extending out of the housing 110 is less than or equal to 30 mm, so as to avoid inconvenience to the user while ensuring the accuracy of the information collected by the detection component 130.

[0118] Since the bottom of the cooking vessel 150 usually has a certain pre-deformation and generally presents a concave structure, when the cooking vessel 150 is heated on the cooking appliance, the temperature of the cooking vessel 150 gradually rises. Due to thermal expansion and contraction, the concavity of the cooking vessel 150 is further aggravated, that is, the distance between the center of the bottom of the cooking vessel and the panel of the housing 110 becomes larger. On the contrary, when the cooking vessel 150 presents a convex structure, as the temperature of the cooking vessel 150 rises, due to thermal expansion and contraction, the convexity of the cooking vessel 150 will be further aggravated. The direction of the concavity or convexity of a frying pan after being heated is uncertain due to thermal expansion and contraction. However, whether it is concave or convex, its bottom will become non-planar. After the cooking vessel 150 is concave or convex, the maximum distance L from the curved surface of the cooking vessel 150 to the top wall 111 is usually less than 10 mm. It is only necessary to make the distance of the detection component 130 exceeding the top wall 111 greater than 10 mm. And after the detection component 130 is under pressure, the distance of the part exceeding the top wall 111 can be less than or equal to 0 mm.

[0119] In an embodiment of the present invention, a control method for a cooking appliance is proposed, which is used for the cooking appliance in any of the above embodiments.

[0120] As Figure 10 shown, the control method of the cooking appliance includes:

[0121] Step 202, collecting the temperature value of the cooking vessel and the position parameter of the cooking vessel relative to the housing;

[0122] Step 204, determining the heating power of the heating element according to the temperature value and the position parameter;

[0123] Step 206, controlling the operation of the heating element according to the heating power.

[0124] The heating element is installed in the housing, and the heating element can heat the cooking vessel, so that the food in the cooking vessel can be cooked. The detection component is installed on the heating element or the housing. During the cooking process, the detection component can detect the temperature and position of the cooking vessel, and adjust the heating power of the heating element according to the detected temperature value and position parameter, so as to adjust the heating fire of the cooking vessel.

[0125] In the related art, the cooking appliance adjusts the firepower of the heating component only by the detected temperature value. During the cooking process, due to the actions of stir-frying (vibrating the cooking vessel up and down, or causing the cooking vessel to move in plane), lifting the pot (moving the cooking vessel up and down), and moving the pot (moving the cooking vessel in plane, inconsistent with the contact position of the cooking vessel, and changes in compression), the temperature value detected by the cooking appliance may decrease, thereby reducing the firepower of the heating component. However, in the process of stir-frying, lifting the pot and moving the pot, high firepower is often required for cooking, which conflicts with the control of the heating component by the cooking appliance, thus affecting the cooking effect.

[0126] In the present invention, the detection component detects both the temperature value of the cooking vessel and the position parameter of the cooking vessel. It can identify whether the user is currently performing a cooking action based on the position of the cooking vessel relative to the shell, and then the firepower of the heating element can be adjusted in a targeted manner to avoid the situation where the firepower is reduced during the cooking process, which is beneficial to improving the cooking effect of the cooking appliance.

[0127] In some embodiments, optionally, collecting the position parameters of the cooking vessel relative to the shell includes: collecting N position parameters within a set time; determining the heating power of the heating element according to the temperature value and the position parameters, including: determining the position parameter fluctuation value according to the N position parameters; increasing the heating power of the heating element based on the position parameter fluctuation value being greater than the set value; determining the heating power of the heating element according to the temperature value based on the position parameter fluctuation value being less than or equal to the set value.

[0128] During the cooking process, it is necessary to collect N position parameters within a set time period, for example, collect 120 times within 120 seconds, process the collected N position parameters, and obtain the position parameter fluctuation value. The position parameter fluctuation value is used to reflect the fluctuation of the N position parameters within the set time. If the position parameter fluctuation value is greater than the set value, it means that the fluctuation of the N position parameters is large. At this time, the user is performing stir-fry cooking. The demand for high-power cooking can be met by increasing the heating power of the heating element. If the position parameter fluctuation value is less than or equal to the set value, it means that the fluctuation of the N position parameters is small. At this time, the position change of the cooking vessel is small. The heating power of the heating element can be controlled according to the temperature value of the cooking vessel. For example, when the temperature of the cooking vessel is low, the heating power of the heating element is increased, and when the temperature of the cooking vessel is high, the heating power of the heating element is reduced. Controlling the heating power of the heating element by temperature value and position parameter is conducive to improving the cooking effect of the cooking utensils.

[0129] During the stir-frying process, due to actions such as stir-frying, lifting the pot, and moving the pot, the size of the detection component passing through the detection hole changes frequently, resulting in relatively large fluctuations in the sampling value of the force detection element. In the program, by recognizing this fluctuation, it is determined that the user is stir-frying. At this time, the influence of temperature is ignored, and the heating power of the heating element is increased. When the sampling value of the force detection element gradually stabilizes, the firepower is controlled according to the temperature value.

[0130] Exemplarily, the position parameter fluctuation value is the variance of N position parameters, or the position parameter fluctuation value is the average value or standard deviation of N position parameters.

[0131] In an embodiment of the present invention, a control device for a cooking appliance is proposed, which is used for the cooking appliance in any of the above embodiments.

[0132] As Figure 11 shown, the control device 300 of the cooking appliance includes:

[0133] An acquisition module 310 that acquires the temperature value of the cooking utensil to be cooked and the position parameter of the cooking utensil to be cooked relative to the housing;

[0134] A determination module 320 that determines the heating power of the heating element according to the temperature value and the position parameter;

[0135] A control module 330 that controls the operation of the heating element according to the heating power.

[0136] The heating element is installed in the housing, and the heating element can heat the cooking utensil to be cooked, so that the ingredients in the cooking utensil can be cooked. The detection component is installed on the heating element or the housing. During the cooking process, the detection component can detect the temperature and position of the cooking utensil to be cooked, and adjust the heating power of the heating element according to the detected temperature value and position parameter, so as to adjust the heating firepower of the cooking utensil to be cooked.

[0137] In the related art, the cooking appliance only adjusts the firepower of the heating component through the detected temperature value. During the user's stir-frying process, due to actions such as stir-frying (vibrating the cooking utensil to be cooked up and down, or causing the cooking utensil to be cooked to move horizontally), lifting the pot (moving the cooking utensil to be cooked up and down), and moving the pot (moving the cooking utensil to be cooked horizontally, with inconsistent contact positions with the cooking utensil to be cooked and changing compression), at this time, the temperature value detected by the cooking appliance may decrease, thereby reducing the firepower of the heating component. However, during the stir-frying, lifting the pot, and moving the pot processes, high firepower is often required for cooking, which conflicts with the control of the heating component by the cooking appliance, thus affecting the cooking effect.

[0138] In the present invention, the detection component detects both the temperature value of the cooking utensil to be cooked and the position parameter of the cooking utensil to be cooked. It can identify whether the user is currently performing a stir-frying action according to the position of the cooking utensil to be cooked relative to the housing, and then can adjust the heating power of the heating element accordingly, avoiding the occurrence of a decrease in heating power during the stir-frying process, which is beneficial to improving the cooking effect of the cooking appliance.

[0139] In some embodiments, optionally, the acquisition module is specifically configured to: acquire N position parameters within a set time period; the determination module is specifically configured to: determine a position parameter fluctuation value according to the N position parameters; based on the position parameter fluctuation value being greater than a set value, increase the heating power of the heating element; based on the position parameter fluctuation value being less than or equal to the set value, determine the heating power of the heating element according to the temperature value.

[0140] During the cooking process, it is necessary to acquire N position parameters within a set time period. For example, acquire 120 times within 120 seconds, process the acquired N position parameters to obtain a position parameter fluctuation value. The position parameter fluctuation value is used to reflect the fluctuation of the N position parameters within the set time. If the position parameter fluctuation value is greater than the set value, it means that the fluctuation of the N position parameters is large, and at this time the user is performing stir-frying cooking, and the heating power of the heating element can be increased to meet the demand for high-fire cooking. If the position parameter fluctuation value is less than or equal to the set value, it means that the fluctuation of the N position parameters is small, and at this time the position change of the cooking utensil to be cooked is small, and the heating power of the heating element can be controlled according to the temperature value of the cooking utensil to be cooked. For example, when the temperature of the cooking utensil to be cooked is low, increase the heating power of the heating element, and when the temperature of the cooking utensil to be cooked is high, decrease the heating power of the heating element. Controlling the heating power of the heating element through the temperature value and the position parameter is beneficial to improving the cooking effect of the cooking appliance.

[0141] As Figure 12 shown, in an embodiment of the present invention, a control device 400 for a cooking appliance is proposed, including a memory 410 and a processor 420. The memory 410 stores a program or instruction that can run on the processor 420. When the program or instruction is executed by the processor 420, it implements the steps of the control method of the cooking appliance in any of the above embodiments and can achieve the same technical effect, which will not be elaborated here.

[0142] In an embodiment of the present invention, a readable storage medium is proposed, on which a program or instruction is stored. When the program or instruction is executed by a processor, it implements the steps of the control method of the cooking appliance in any of the above embodiments and can achieve the same technical effect, which will not be elaborated here.

[0143] The described methods can be implemented in various different ways according to specific features and / or example applications. For example, these methods can be implemented by a combination of hardware, firmware, and / or software. For example, in a hardware implementation, a processor can be implemented in one or more application-specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field-programmable gate arrays (FPGAs), controllers, microcontrollers, microprocessors, electronic devices, other device units for performing the above functions, and / or combinations thereof.

[0144] A readable storage medium can be a tangible device that can retain and store instructions for use by an instruction execution device. A readable storage medium can be an electronic storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination of the above devices, without limitation. A non-exhaustive list of more specific examples of a readable storage medium includes: a portable computer floppy disk, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or flash memory), a static random access memory (SRAM), a portable compact disc read-only memory (CD-ROM), a digital versatile disk (DVD), a memory card, a floppy disk, a coding mechanical device (such as a punched card or a groove with a raised structure recording instructions), and any suitable combination of the above devices. A readable storage medium as used herein should not be construed as a signal per se, such as a radio wave or other freely propagating electromagnetic wave, an electromagnetic wave propagating through a waveguide or other transmission medium, or an electrical signal transmitted through a wire, etc.
