Description

Technical Field

[0001] The present application belongs to the technical field of kitchen appliances, and specifically relates to a pot cover assembly and a cooking utensil. Background Art

[0002] The cooking utensil is one of the common kitchen appliances, which comprises a pot body and a pot cover. The pot cover is arranged on the pot body and forms a sealed cooking cavity together with the pot body.

[0003] Existing cooking utensils generally judge the total amount of food in the cooking cavity by the length of time it takes for the top sensor to reach the set temperature after heating for a period of time, and then perform subsequent cooking operations. Before the cooking utensils judge the total amount of food in the cooking cavity, the cooking utensils heat the food in the cooking cavity at the same power. In order to ensure that the total amount of food in the cooking cavity can be heated to the set temperature quickly when the total amount of food in the cooking cavity is large, the power is usually set to be large. However, for the case where the total amount of food in the cooking cavity is small, heating the food at this power easily causes the food at the bottom of the cooking cavity to heat up quickly, which in turn causes the surface of the food at the bottom of the cooking cavity to gelatinize and the inside to be raw, thereby affecting the user's experience. At the same time, judging the amount of food in the cooking cavity by the length of time it takes for the top sensor to reach the set temperature after heating for a period of time can only roughly judge the amount of food in the cooking cavity, and cannot accurately judge, thereby causing the heating time of the cooking utensils to be unable to be accurately controlled, thereby affecting the cooking effect of the food. In addition, since the amount of food in the cooking cavity cannot be judged in the early stage of cooking, the display can only display a fixed default working time, resulting in the display time decreasing too fast or too slow in the later stage of cooking, affecting the user's experience. Utility Model Content

[0004] The present application provides a pot cover assembly and a cooking utensil, which can accurately control the heating power of the cooking utensil according to the amount of food in the cooking cavity, improve the cooking effect of the food, accurately display the cooking working time, and improve the user experience.

[0005] The technical solution adopted in this application is:

[0006] A pot cover assembly comprises a cover body, wherein the cover body is provided with a detection assembly and a driving member for driving the detection assembly to move in a vertical direction, wherein the detection assembly has a first measuring state in which it contacts liquid material in a cooking cavity and forms a first height signal, and a second measuring state in which it contacts solid material in the cooking cavity and forms a second height signal.

[0007] The pot cover assembly described in this application also includes the following additional technical features:

[0008] The detection component includes a measuring electrode, and the measuring electrode is used to contact with the liquid material to form the first height signal.

[0009] The detection component also includes a reference electrode, which is located above the measuring electrode. When the measuring electrode contacts the liquid material, a potential difference is generated between the measuring electrode and the reference electrode to form the first height signal.

[0010] The detection assembly also includes a pressure sensor and an elastic pressure detection member connected to the pressure sensor, wherein the elastic pressure detection member is used to deform when in contact with the solid material and transmit a signal to the pressure sensor so that the pressure sensor forms the second height signal.

[0011] The cover body comprises a sealing area which cooperates with the pot body to enclose a cooking cavity and an edge area surrounding the sealing area, and the detection component is coaxially arranged with the sealing area.

[0012] The detection component includes a detection member and a transmission member, the transmission member includes a meshing tooth and a matching tooth meshing and transmission connected with the meshing tooth, the meshing tooth is transmission connected with the driving member, and the detection member is arranged on the matching tooth.

[0013] The detection component includes a detection member and a transmission member, the transmission member includes a pulley block and a lifting rope, and two ends of the lifting rope are respectively connected to the detection member and the output end of the driving member and are arranged around the pulley block.

[0014] The detection component also includes a plurality of lifting members, and the lifting members are a telescopic structure that is nested layer by layer from the outside to the inside.

[0015] The detection assembly includes a transmission member transmission-connected to the driving member, and a detection member detachably connected to the transmission member.

[0016] The present application also discloses a cooking utensil, comprising a pot body and the pot cover assembly, wherein the pot cover assembly is disposed on the pot body and cooperates with the pot body to form a cooking cavity, and the detection assembly is located on the central axis of the cooking cavity.

[0017] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0018] 1. The pot cover assembly in the present application includes a cover body, the cover body is provided with a detection assembly and a driving member for driving the detection assembly to move in a vertical direction, the detection assembly has a first measuring state in which it contacts with liquid material in a cooking cavity and forms a first height signal, and a second measuring state in which it contacts with solid material in the cooking cavity and forms a second height signal. It can be understood that when measuring the amount of food in the cooking cavity, the driving member drives the detection assembly to move the detection assembly in a vertical direction, and then moves the detection assembly to the first measuring state, the detection assembly contacts with liquid material in the cooking cavity and forms a first signal, the driving member continues to drive the detection assembly to move the detection assembly to the second measuring state, and the detection assembly contacts with liquid material in the cooking cavity and forms a first signal. The detection component contacts the solid material in the cooking cavity and forms a second height signal, so that the control component of the cooking appliance calculates the total amount of food and the amount of solid material in the cooking cavity according to the position of the detection component when the first height signal and the second height signal are sent, and at the same time calculates the amount of liquid material using the total amount of food and the amount of solid material, and then selects the appropriate heating power, accurately controls the heating time, and accurately displays the required cooking time according to the amount of liquid material and solid material, so as to improve the cooking effect of the food in the cooking cavity, improve the cooking taste of the food, avoid the situation that the surface of the food at the bottom of the cooking cavity is gelatinized, the inside is caught raw, and the cooking time decreases too quickly or too slowly, thereby improving the user experience.

[0019] 2. As a preferred embodiment of the present application, the detection component includes a measuring electrode, which is used to contact the liquid to form a first height signal. When the driving component drives the detection component, the detection component moves in the vertical direction, and then the measuring electrode moves to the first measuring state, so that the measuring electrode contacts the liquid. Since the measuring electrode is exposed to the air in the cooking cavity when it is not moving in the vertical direction, and contacts the liquid when it is in the first measuring state, the potential of the measuring electrode changes when it is in the first measuring state and forms a first height signal, so that the control component of the cooking appliance calculates the total amount of food in the cooking cavity according to the position of the measuring electrode at this time. Because the measuring electrode has the characteristic of high sensitivity, the measurement accuracy of the food amount is increased, the heating power and heating time of the food are accurately controlled, the cooking taste of the food is improved, and the remaining cooking time displayed on the display is more accurate, further improving the user experience.

[0020] 3. As a preferred embodiment of the present application, the detection component also includes a reference electrode, which is located above the measuring electrode. When the measuring electrode contacts the liquid, a potential difference is generated between the measuring electrode and the reference electrode to form a first height signal. It can be understood that when measuring the total amount of food in the cooking cavity, the measuring electrode contacts the liquid. Since the reference electrode is located above the measuring electrode, when the measuring electrode contacts the liquid, the reference electrode does not contact the liquid, that is, the reference electrode is exposed to the air in the cooking cavity, thereby generating a potential difference between the measuring electrode and the reference electrode. This potential difference forms a first height signal, so that the control component calculates the total amount of food in the cooking cavity through the position of the measuring electrode at this time, further increasing the measurement accuracy of the total amount of food, further accurately controlling the heating power and heating time of the food, further improving the cooking taste of the food, and at the same time further making the remaining cooking time displayed on the display more accurate, thereby further improving the user experience.

[0021] 4. As a preferred embodiment of the present application, the detection component also includes a pressure sensor and an elastic pressure detection member connected to the pressure sensor, the elastic pressure detection member is used to contact with the solid material to deform and transmit a signal to the pressure sensor, so that the pressure sensor forms a second height signal. It can be understood that after the detection component moves to the first measurement state, the driving member continues to drive the detection component to move the detection component from the first measurement state to the second measurement state. When the detection component moves to the second measurement state, the elastic pressure detection member contacts the solid material. At this time, the elastic pressure detection member is deformed under the interaction of the driving member and the solid material and transmits a pressure signal to the pressure sensor, so that the pressure sensor forms a second height signal. At this time, the control component calculates the amount of solid material in the cooking cavity according to the position of the elastic pressure detection member, and calculates the amount of liquid material according to the total amount of food in the cooking cavity that has been calculated, so that the control component selects the appropriate heating power and heating time, and accurately displays the time required for cooking on the display, thereby improving the cooking taste of the cooking utensils and the user experience.

[0022] 5. As a preferred embodiment of the present application, the cover body has a sealing area that cooperates with the pot body to form a cooking cavity and an edge area surrounding the sealing area. The detection component is coaxially arranged with the sealing area to further increase the accuracy of detecting the amount of food in the cooking cavity, thereby further increasing the precise control of the heating power and heating time, further improving the cooking taste of the food, and at the same time being able to further accurately display the required cooking time, thereby further improving the user experience. In addition, the travel of the detection component in the vertical direction can be increased to increase the range that the detection component can measure, ensure the normal operation of the cooking appliance, increase the flexibility of the cooking appliance, and further improve the user experience.

[0038] Reference Figures 1 to 4 A pot cover assembly includes a cover body, the cover body is provided with a detection assembly 1 and a driving member for driving the detection assembly 1 to move in a vertical direction, the detection assembly 1 has a first measuring state of contacting liquid material in a cooking cavity 2 and forming a first height signal and a second measuring state of contacting solid material in the cooking cavity 2 and forming a second height signal.

[0039] When measuring the amount of food in the cooking cavity 2, the driving component drives the detection component 1 to move the detection component 1 in the vertical direction, and then the detection component 1 moves to the first measurement state, the detection component 1 contacts the liquid in the cooking cavity 2 and forms a first signal, and the driving component continues to drive the detection component 1 to move the detection component 1 to the second measurement state, the detection component 1 contacts the solid in the cooking cavity 2 and forms a second height signal, so that the control component of the cooking appliance calculates the total amount of food and the amount of solid in the cooking cavity 2 according to the position of the detection component 1 when the first height signal and the second height signal are sent, and calculates the amount of liquid by using the total amount of food and the amount of solid, and then selects the appropriate heating power according to the amount of liquid and solid, accurately controls the heating time, and accurately displays the required cooking time, so as to improve the cooking effect of the food in the cooking cavity 2, improve the cooking taste of the food, avoid the gelatinization of the surface of the food at the bottom of the cooking cavity 2, avoid the situation that the food inside is raw, and avoid the situation that the cooking time decreases too fast or too slow, thereby improving the user experience.

[0040] In addition, the existing method of measuring the amount of food in the cooking cavity also includes measuring through ultrasonic sensors or infrared sensors, while the technical solution in the present application measures the amount of food in the cooking cavity by directly contacting the liquid or solid material, thereby increasing the accuracy of the measurement and avoiding the situation where boiling food adheres to the sensor and affects the sensor's operation during cooking, thereby improving the user experience.

[0041] The present application does not specifically limit the method for measuring the total amount of food in the cooking cavity 2, and any one of the following embodiments may be adopted:

[0042] Embodiment 1: In this embodiment, the detection component 1 includes a measuring electrode 11, and the measuring electrode 11 is used to contact with the liquid material and form a first height signal.

[0043] When the driving component drives the detection component 1, the detection component 1 moves in the vertical direction, and then the measuring electrode 11 moves to the first measuring state, so that the measuring electrode 11 contacts the liquid. Since the measuring electrode 11 is exposed to the air in the cooking cavity 2 when it is not moving in the vertical direction, and contacts the liquid when it is in the first measuring state, the potential of the measuring electrode 11 changes when it is in the first measuring state and forms a first height signal, so that the control component of the cooking appliance calculates the total amount of food in the cooking cavity 2 according to the position of the measuring electrode 11 at this time. Because the measuring electrode 11 has the characteristic of high sensitivity, the measurement accuracy of the food amount is increased, the heating power and heating time of the food are accurately controlled, the cooking taste of the food is improved, and at the same time the remaining cooking time displayed on the display is more accurate, further improving the user experience.

[0044] Implementation method 2. In this implementation method, refer to Figures 1 to 4 The detection component 1 also includes a reference electrode 12, which is located above the measuring electrode 11. When the measuring electrode 11 contacts the liquid material, a potential difference is generated between the measuring electrode 11 and the reference electrode 12 to form a first height signal.

[0045] When measuring the total amount of food in the cooking cavity 2, the measuring electrode 11 is in contact with the liquid. Since the reference electrode 12 is located above the measuring electrode 11, when the measuring electrode 11 is in contact with the liquid, the reference electrode 12 is not in contact with the liquid, that is, the reference electrode 12 is exposed to the air in the cooking cavity 2, thereby generating a potential difference between the measuring electrode 11 and the reference electrode 12. This potential difference forms a first height signal, so that the control component calculates the total amount of food in the cooking cavity 2 through the position of the measuring electrode 11 at this time, further increasing the measurement accuracy of the total amount of food, further accurately controlling the heating power and heating time of the food, further improving the cooking taste of the food, and at the same time further making the remaining cooking time displayed on the display more accurate, thereby further improving the user experience.

[0046] The present application does not specifically limit the structures of the measuring electrode 11 and the reference electrode 12. Preferably, the measuring electrode 11 and the reference electrode 12 are both metal rods. In other implementation examples, the measuring electrode 11 and the reference electrode 12 can also be metal sheets.

[0047] In a preferred embodiment, referring to Figures 1 to 4 The detection assembly 1 also includes a pressure sensor 13 and an elastic pressure detection member 14 connected to the pressure sensor 13. The elastic pressure detection member 14 is used to deform when in contact with the solid material and transmit a signal to the pressure sensor 13, so that the pressure sensor 13 forms a second height signal.

[0048] After the detection component 1 moves to the first measuring state, the driving member continues to drive the detection component 1 to move the detection component 1 from the first measuring state to the second measuring state. When the detection component 1 moves to the second measuring state, the elastic pressure detection component 14 contacts the solid material. At this time, the elastic pressure detection component 14 is deformed under the interaction of the driving member and the solid material and transmits a pressure signal to the pressure sensor 13, so that the pressure sensor 13 forms a second height signal. At this time, the control component calculates the amount of solid material in the cooking cavity 2 according to the position of the elastic pressure detection component 14, and calculates the amount of liquid material according to the calculated total amount of food in the cooking cavity 2, so that the control component selects the appropriate heating power and heating time, and accurately displays the cooking time required on the display, thereby improving the cooking taste of the cooking utensils and the user experience.

[0049] The present application does not specifically limit the structure of the elastic pressure detection member 14. Preferably, refer to Figures 1 to 4 The elastic pressure detection member 14 is a spiral tube piezoelectric spring, which can undergo a large deformation under a small external force to increase the sensitivity of the detection component 1, improve the measurement accuracy of the solid material, and thus improve the accuracy of the heating power control and the cooking time control, while improving the accuracy of the cooking time displayed on the cooking utensil, thereby improving the cooking effect of the food and the user experience. In other embodiments, the elastic pressure detection member 14 can also be other elastic structures, as long as it can achieve elastic pressure detection and contact with the solid material and apply pressure to the pressure sensor 13.

[0050] Better, refer to Figure 1 , Figure 2 and Figure 4 The measuring electrode 11 is hollow inside and integrated with an electrode sheet 111. The spiral tube piezoelectric spring is located inside the measuring electrode 11 and above the electrode sheet 111. The electrode sheet 111 is flush with the bottom of the measuring electrode 11 to further increase the accuracy of the measurement.

[0051] Reference Figures 1 to 4 When using a cooking utensil to cook rice, when the measuring electrode 11 contacts water, a potential difference will be generated between it and the reference electrode 12. It can be considered that the detection component 1 contacts water. At this time, the total height H1 of the food in the cooking chamber 2 can be measured based on the movement of the driving member. At this time, the tension of the water is small, and the deformation of the elastic pressure detection member 14 can be ignored. When the detection component 1 continues to move downward and contacts the rice, the deformation of the elastic pressure detection member 14 will change significantly. The pressure sensor 13 receives a sudden change in force, and the control component sets the force to F (F can be set to an empirical value of 5N. When it is greater than 5N, it is considered to contact the rice). At this time, the height H2 of the rice in the cooking chamber 2 can be measured based on the movement of the driving member. In the initial state, the distance from the detection component 1 to the bottom of the cooking chamber 2 is H (this value is measured and calibrated before leaving the factory). The water capacity V1 can be calculated from this, V1 = π × R 2 ×(H1-H2), the capacity of rice is V2, V2=π×R 2 ×H2, R is the radius of the cooking chamber 2, and the volume of water in the rice is not included in the calculation.

[0052] Through the measurement of this detection component 1, the capacity of rice and water in the cooking cavity 2 can be accurately measured and calculated at the beginning of the cooking operation. The control component can set the optimal heating power for each cooking stage according to the calculation results, so that when cooking a small amount of rice, undesirable phenomena such as burnt brown and undercooked will not occur. When cooking a large amount of rice, it can also reach boiling as soon as possible, and the top of the rice will not become hard or undercooked due to less heating steam in the later stage. When it is measured that the amount of rice is large and the amount of water is small, the control component reduces the heating power in the boiling stage to prevent the loss of water too quickly, the lack of water in the later stage of cooking, and the top being undercooked; when it is measured that the amount of rice is small and the amount of water is large, the control component increases the heating power in the boiling stage to evaporate as much excess water as possible to improve the situation of wet rice.

[0053] The present application does not make any specific limitation on the positional relationship between the detection component 1 and the cover body. Preferably, the cover body has a sealing area that cooperates with the pot body to enclose the cooking cavity 2 and an edge area surrounding the sealing area. The detection component 1 is coaxially arranged with the sealing area, that is, the detection component 1 is located at the center of the sealing area to further increase the accuracy of detecting the amount of food in the cooking cavity 2, thereby further increasing the precise control of the heating power and the heating time, further improving the cooking taste of the food, and at the same time being able to further accurately display the required cooking time, thereby further improving the user experience. In addition, the travel of the detection component 1 in the vertical direction can also be increased to increase the range that the detection component 1 can measure, ensure the normal operation of the cooking utensil, increase the flexibility of the cooking utensil, and further improve the user experience. In other embodiments, the detection component 1 can also be located on the side of the sealing area close to the edge area.

[0054] The present application does not specifically limit the position of the driving member. Preferably, at least part of the driving member is located inside the cover body to reasonably utilize the internal space of the cover body, reduce the size of the pot cover assembly, and improve the space utilization rate inside the cover body, so as to miniaturize the pot cover assembly. In other embodiments, the driving member can also be arranged on the lower surface of the cover body to facilitate the installation and maintenance of the driving member.

[0055] The present application does not specifically limit the structure of the driving member, and it may adopt any one of the following embodiments:

[0056] Embodiment 1: In this embodiment, the driving member is an electric push rod, which is arranged vertically on the cover body, and the detection assembly 1 is connected to the end of the piston rod of the electric push rod, so that when the electric push rod performs telescopic movement, it drives the detection assembly 1 to move in the vertical direction, so as to realize the driving of the detection assembly 1, thereby increasing the movement stability of the detection assembly 1. At the same time, it is convenient to calculate the amount of food in the cooking cavity according to the extension amount of the piston rod of the electric push rod, so as to increase the accuracy of the measurement.

[0057] Implementation method 2: In the implementation method, refer to Figures 1 to 4 The detection component 1 includes a detection member and a transmission member 3. The driving member is a motor. The output shaft of the motor is connected to the transmission member 3 to realize the movement of the transmission member 3 in the vertical direction.

[0058] The present application does not specifically limit the structure of the transmission member 3, and it may adopt any one of the following embodiments:

[0059] Embodiment 1, in this embodiment, refer to Figure 1 , Figure 2 and Figure 3 The transmission member 3 includes a meshing tooth 31 and a matching tooth 32 meshing and transmission-connected with the meshing tooth 31 . The meshing tooth 31 is transmission-connected with the driving member, and the detection member is arranged on the matching tooth 32 .

[0060] Specifically, the transmission member 3 includes a gear with meshing teeth 31 and a rack with matching teeth 32. The gear and the rack are meshingly connected, and the gear is coaxially fixedly connected to the output end of the driving member. The rack is arranged parallel to the vertical direction so that when the output shaft of the driving member rotates, the gear is driven to rotate, and the gear and the rack rotate relative to each other, so that the rack moves in the vertical direction.

[0061] Preferably, two gears and two racks are provided, and the racks and gears are arranged in one-to-one correspondence, the two gears are meshed and transmitted, and the output end of the driving member is coaxially fixedly connected to one of the gears to increase the stability of the detection component 1 when it moves in the vertical direction, thereby ensuring the accuracy of the measurement of food in the cooking cavity 2.

[0062] Embodiment 2, in this embodiment, refer to Figure 4 The transmission member 3 includes a pulley block 33 and a lifting rope 34 . The two ends of the lifting rope 34 are respectively connected to the output ends of the detection member and the driving member and are arranged around the pulley block 33 .

[0063] When the driving member is working, the output end of the driving member rotates, and then the lifting rope 34 is wound to the output end of the driving member or unwound from the output end of the driving member, so that the pulley group 33 and the lifting rope 34 roll relative to each other, and at the same time, the end of the lifting rope 34 away from the output end of the driving member rises or falls to achieve the lifting or lowering of the detection member, thereby reducing the workload of the driving member and increasing the service life of the driving member.

[0064] The present application does not impose any specific limitation on the number of pulleys in the pulley block 33 , which may include only one pulley or multiple pulleys. As long as the load on the driving component can be reduced during operation, any number of pulleys in the pulley block 33 is acceptable.

[0065] The present application does not specifically limit the structure of the detection element, which at least includes the measuring electrode 11, the pressure sensor 13 and the elastic pressure detection element 14 in the above-mentioned embodiment.

[0066] In a preferred embodiment, referring to Figure 4 The detection component 1 also includes a plurality of lifting members 4, which are telescopic structures nested from the outside to the inside to increase the movement range of the detection component 1, so that the detection component 1 can work in a larger range to ensure the normal operation of the cooking appliance and increase the flexibility of the cooking appliance.

[0067] The present application does not make any specific limitation on the structure of the lifting member 4. Preferably, the lifting member 4 is a tubular structure to reduce the weight of the lifting member 4, thereby reducing the weight of the pot cover assembly, thereby facilitating the user to operate the pot cover assembly, and improving the user's operating convenience and user experience.

[0068] In a preferred embodiment, the detection assembly 1 includes a transmission member 3 transmission-connected to the driving member, and a detection member detachably connected to the transmission member 3 .

[0069] Since the detection member is in direct contact with the food when measuring the food in the cooking cavity 2, the detection member needs to be cleaned. The detection member is arranged to be detachably connected to the transmission member 3, which can be convenient for the user to disassemble and assemble the detection member according to needs, so that the user can clean the detection member, improve the cleanliness of the cooking utensils, avoid the situation of food odor contamination during cooking, thereby improving the cooking effect and cooking taste of the food, and further improving the user experience.

[0070] The present application does not specifically limit the detachable connection method between the detection member and the transmission member 3, and any one of the following embodiments may be adopted:

[0071] Embodiment 1. In this embodiment, the detection member is provided with an elastic arm, a clamping protrusion is provided on one side of the elastic arm, and the transmission member 3 is provided with a clamping groove corresponding to the elastic clamping arm. When the detection member is installed on the transmission member 3, the elastic arm is first aligned with the clamping groove, and then pressure is applied to the detection member in the direction of the transmission member 3 so that the clamping protrusion contacts the notch of the clamping groove, and then the detection member is pressed continuously to deform the elastic arm, and the clamping protrusion enters the clamping groove, and the elastic arm recovers its deformation and clamps with the clamping groove. When the detection member is disassembled, the detection can be reversed.
