[0081] For example, "upper" and "lower" in this application refer to the cooking utensil in use, or when the cooking utensil is placed on the table with the lid closed. "Inside" and "outside" in this application refer to the central position of the cooking space.

[0082] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings.

[0083] The cooking utensil of the present application generally comprises a pot body and a cover body 100. The pot body is basically in the shape of a rounded rectangular parallelepiped, and has a middle plate and an outer shell connected to the lower side of the middle plate, and the two can be integrally injection molded.

The inner pot is generally made of metal material and has a circular opening on the upper surface, which is used to hold materials to be heated, such as rice, soup, etc.

[0084] The cover 100 has a shape substantially corresponding to that of the pot body. The cover 100 is arranged on the pot body in an openable and closable manner. Specifically, the cover 100 is pivotally connected to the pot body via a pivot shaft and can freely pivot between a closed position and an open position relative to the pot body around a pivot axis where the pivot shaft is located, so as to facilitate closing and opening of the pot body. When the cover 100 is closed on the pot body, it covers the inner pot and forms a cooking space between the cover 100 and the inner pot.

[0085] The cooking appliance also has a lid opening torsion spring connected between the pot body and the lid body 100 to provide power for opening the lid body 100. Specifically, the lid opening torsion spring may have a first torsion spring arm and a second torsion spring arm, wherein the first torsion spring arm is connected to the lid body 100 and the second torsion spring arm is connected to the pot body.

[0086] The cooking appliance includes a control device and a heating module. The control device is used to achieve the purpose of cooking control of the cooking appliance, and the control device may be an MCU (Micro Control Unit). The heating module is used to heat the inner pot, and the heating module may be a coil disk. The control device is electrically connected to the heating module to achieve control of the heating process.

[0087] For the specific structure of the cover 100, please refer to Figures 1 to 17, which includes a surface cover 101, an inner lining 102, an infrared emitting assembly and a removable cover 108, wherein the inner lining 102 is arranged below the surface cover 101 and connected to the surface cover 101. The infrared emitting assembly can emit infrared rays to assist in cooking the food in the cooking space. The inner lining 102 has a second through hole 103, and the infrared emitting assembly is arranged on the inner lining 102 and corresponds to the second through hole 103, so that the infrared emitting assembly is above the inner pot. When the cover body 100 is covered on the pot body, the infrared rays radiated by the infrared emitting assembly pass through the second through hole 103 to assist in heating the cooking space. The removable cover 108 is arranged below the inner lining 102 and connected to the inner lining 102.

[0088] For the specific structure of the infrared emission component, please refer to Figures 1 to 17 , which includes a transmission member 104, a support frame 110, ore particles 150 and a snap-on cover 140, wherein the support frame 110 is arranged on the upper side of the transmission member 104, the support frame 110 includes a loading wall 112 surrounding a first through hole 113, the loading wall 112 and the transmission member 104 form a receiving space, and a partition rib 114 connected to the loading wall 112 is arranged in the first through hole 113, and the partition rib 114 divides the receiving space into a plurality of receiving areas 118. A plurality of ore particles 150 are loaded in the plurality of receiving areas 118, and the ore particles 150 can emit infrared rays. For example, the ore particles 150 can be tourmaline. The snap-on cover 140 is arranged on the upper side of the loading wall 112 to close the receiving space. Preferably, the snap-on cover 140 is fixedly connected to the liner 102, so that the infrared emitting component can be firmly connected to the liner 102, thereby improving the stability of the product.

[0089] According to the infrared emission assembly of the present application, a plurality of mineral particles 150 are laid flatly and evenly in each receiving area 118, which is conducive to the infrared rays generated by the mineral particles 150 to fully radiate the cooking space and enhance the auxiliary cooking effect. By closing the receiving space with the snap-fit ​​cover 140, it is possible to prevent the mineral particles 150 from falling off or shaking and producing abnormal noises, thereby improving the safety performance of the product.

[0090] For the specific structure of the separation rib 114, please refer to Figure 3 , Figure 4 and Fig.10 , which includes a first dividing rib 115, wherein both ends of the first dividing rib 115 are connected to the loading wall 112 so that the accommodating space is divided into a plurality of accommodating areas 118, so that a plurality of ore particles 150 are closely laid in the corresponding accommodating areas 118, thereby improving the infrared radiation intensity of the ore particles 150 and reducing the friction or collision between the ore particles 150.

[0091] like Figure 3 , Figure 4 and Fig.10As shown, the dividing ribs 114 further include a second dividing rib 116 connected between the two first dividing ribs 115. The space between the two first dividing ribs 115 is divided into at least two sequentially arranged containing areas 118 by the second dividing rib 116, and the number of the containing areas 118 is ensured, so that the plurality of ore particles 150 are evenly and evenly laid in each containing area 118.

[0092] like Figure 3 , Figure 4 and Fig.10 As shown, the partition rib 114 further includes a third partition rib 117 connected between the second partition rib 116 and the loading wall 112. The space between the second partition rib 116 and the loading wall 112 is divided into at least two sequentially arranged accommodating areas 118 by the second partition rib 116, further increasing the number of accommodating areas 118, thereby further enhancing the intensity of infrared radiation and improving the auxiliary cooking effect.

[0093] In an optional embodiment, the partition rib 114 further includes a fourth partition rib connected between the first partition rib 115 and the loading wall 112; and / or the partition rib 114 further includes a fifth partition rib connected between the two second partition ribs 116. The space between the first partition rib 115 and the loading wall 112 and / or the space between the two second partition ribs 116 is divided into at least two sequentially arranged accommodating areas 118 by the fourth partition rib, ensuring that the accommodating space is divided into a plurality of regularly shaped accommodating areas 118, and the infrared radiation intensity is substantially the same.

[0094] For example, the separation rib 114 is constructed in a straight line and / or an arc shape. Since the ore particles 150 are small and irregular in shape, they are prone to shaking. The separation rib 114 is constructed in a straight line and / or an arc shape, and the ore particles 150 can be tightly connected with the separation rib 114. The assembly structure is simple and tightly fitted, which can reduce the probability of collision or friction between the ore particles 150.

[0095] As an optional implementation, the number of the accommodating areas 118 is 3-15. If the accommodating areas 118 are too few, the gaps between the ore particles 150 are too large, and the ore particles 150 are prone to shaking; if the accommodating areas 118 are too large, there are fewer ore particles 150 in each accommodating area 118, and the infrared radiation effect is poor.

[0096] As an optional embodiment, the shape of the accommodating area 118 includes at least part of a circle, square, ring, triangle, polygon or sector, so that the accommodating area 118 has different shapes, the design is more layered, and it is conducive to enhancing user favorability.

[0097] like Figure 2 and Fig. 9As shown, the support frame 110 further includes a mounting portion 111 disposed around the loading wall 112, wherein the mounting portion 111 is at least partially in contact with the transmissive member 104, ensuring that the transmissive member 104 is firmly connected to the support frame 110, and enhancing the stability of the infrared emitting assembly; and / or the transmissive member 104 has a transmissive region 105 and a non-transmissive region 106, the transmissive region 105 corresponds to the first through opening 113 surrounded by the loading wall 112, and the non-transmissive region 106 is connected to the support frame 110, specifically, the non-transmissive region 106 is connected to the mounting portion 111 of the support frame 110. Thus, the infrared rays generated by the ore particles 150 can be radiated outward through the transmissive region 105, ensuring the infrared assisted cooking effect.

[0098] like Figure 2 and Fig. 9 As shown, the infrared emission assembly further includes a flexible sealing pad 107, wherein the flexible sealing pad 107 is disposed on the periphery of the transmission member 104, and the flexible sealing pad 107 is connected between the support frame 110 and the transmission member 104, and / or connected between the snap-fit ​​cover 140 and the transmission member 104. The flexible sealing pad 107 improves the sealing performance of the infrared emission assembly, enhances the connection strength between the transmission member 104 and the support frame 110 and the snap-fit ​​cover 140, and ensures the safety performance of the product. In this embodiment, the flexible sealing pad 107 is connected between the support frame 110 and the transmission member 104.

[0099] The infrared emission assembly also includes a heating device 120 for heating the ore particles 150, wherein the heating device 120 is disposed on the lower side of the snap-fit ​​cover 140, and the ore particles 150 can be heated to excite infrared rays, and the infrared rays are excited by the heating device 120, so that the infrared auxiliary heating effect is good and the cost is low, and the installation is convenient, which effectively improves the auxiliary cooking effect of the infrared emission assembly. Optionally, the heating device 120 can be configured as a heating wire, which has the advantages of low cost, large specific surface area, and simple installation.

[0100] Preferably, the infrared emission component also includes a temperature sensor, and the heating device 120 and the temperature sensor are both coupled to the control device, so that the control device can control the operation of the heating device 120 based on the temperature of the mineral particles 150, so that the mineral particles 150 are maintained in a suitable temperature range to radiate infrared rays that are beneficial to stimulating the flavor substances of the food, such as infrared rays with a wavelength of 2-16μm, and at the same time, prevent the heating temperature from being too high, which may cause heat aging of the parts of the cooking utensil.

[0101] The power of the heating device 120 is 5W to 500W, preferably 25W, which not only ensures that the ore particles 150 are heated and efficiently stimulate infrared rays to irradiate food, but also reduces the risk of heat aging of the cooking utensils' parts.

[0102] like Figure 2 , Figure 6 and Fig. 9 As shown, the infrared emission assembly further includes a flexible pad 130, wherein the flexible pad 130 is installed on the inner side of the loading wall 112 to press and fix the ore particles 150, so as to prevent the ore particles 150 from shaking and causing friction or collision between the ore particles 150. The bottom side of the snap-fit ​​cover 140 preferably has a pressing rib 141 extending in a direction toward the transmission member 104, and the pressing rib 141 abuts against the flexible pad 130, so that the ore particles 150 are clamped between the flexible pad 130 and the support frame 110, further improving the stability of the infrared emission assembly.

[0103] As an optional embodiment, the snap-on cover 140 is further provided with a torsion spring positioning portion 143, which is used to limit the opening torsion spring of the cooking utensil. For example, the first torsion spring arm of the opening torsion spring can be limited at the torsion spring positioning portion 143.

[0104] For the specific structure of the flexible pad 130, please refer to Figure 5 and Figure 6 , which includes a pad body 131 and a plurality of synapses 132, wherein the synapses 132 extend from the bottom side of the pad body 131 in a direction toward the transmission member 104, so that the ore particles 150 are clamped between two synapses 132 and fit tightly with the synapses 132, preventing the ore particles 150 from moving toward the synapses 132 on both sides, and having a good limiting effect.

[0105] For the detailed structure of synapse 132, please refer to Figure 5 and Figure 6 It includes a columnar portion 133 and a spherical portion 134, wherein the columnar portion 133 is connected to the pad body 131, and the spherical portion 134 is arranged at the end of the columnar portion 133. The two columnar portions 133 enclose a space for accommodating ore particles 150, and the two spherical portions 134 are tightly fitted with the ore particles 150 respectively, with good limiting effect and high stability of the ore particles 150.

[0106] As an optional implementation, the radial size of the spherical portion 134 is adapted to the radial size of the columnar portion 133 , which can better adapt to the size of the ore particles 150 , achieve positioning and fit fixation of the ore particles 150 , and prevent the ore particles 150 from shaking.

[0107] In order to better restrict the movement of the ore particles 150, the relative dimensions of the flexible pad 130 and the synapse 132 need to satisfy a certain relationship with the relative dimensions of the ore particles 150. Figure 6For example, the minimum size of the ore particle 150 along the first direction D1 is a, and the minimum size of the ore particle 150 along the second direction D2 is b, wherein the first direction D1 is a direction substantially perpendicular to the bearing surface of the transmission member 104 bearing the ore particle 150, and the second direction D2 is a direction substantially parallel to the bearing surface. "Substantially perpendicular" refers to a situation where the angle is 90° and the angle is offset by 1 to 2° relative to 90°. In other words, "substantially perpendicular" may refer to an angle of 88 to 92°. "Substantially parallel" refers to a situation where the angle is 0° and the angle is offset by 1 to 2° relative to 0°. In other words, "substantially parallel" may refer to an angle of -2 to 2°.

[0108] The length of the synapse 132 is d. If the length of the synapse 132 is too small, the mineral particles 150 will shake between the synapse 132 and the transmission member 104. If the length of the synapse 132 is too large, it will exceed the fitting clearance, resulting in failure to install. The minimum distance between the bottom surface of the flexible pad 130 and the top surface of the transmission member 104 is h, where ha≤d<h. In this way, the shaking of the mineral particles 150 between the flexible pad 130 and the transmission member 104 can be limited while meeting the installation conditions.

[0109] The distance between the columnar parts 133 of two adjacent synapses 132 is c. If the distance is too large, the ore particles 150 will shake in the gap between the synapses 132. If the distance is too small, it will be difficult to process and shape. Therefore, c≤b must be satisfied. This can reduce the difficulty of processing and shaping, and can also reduce the shaking of the ore particles 150.

[0110] The radial dimension of the columnar portion 133 is e, and satisfies 0<e<b. Preferably, b / 10≤e≤3b / 10. More preferably, e=b / 5. Such parameter conditions can more fully fill the gaps between the ore particles 150.

[0111] The distance between the columnar parts 133 of two adjacent synapses 132 is c, the radial dimension of the columnar part 133 is e, and c+e=i×b, where 0.95≤i≤1.05. Such parameter setting enables the ore particle 150 to be stuck just between the two synapses 132. As an optional embodiment, refer to Figure 2 As shown, the heating device 120 is disposed on the upper side of the flexible pad 130, which is conducive to the rapid transfer of heat generated by the heating device 120 to the ore particles 150, improving the heat conduction efficiency and preventing heat loss. Figure 7 and Figure 8 As shown, the pressing rib 141 is at least partially interrupted to form a notch 142 to avoid the heating wire, which is beneficial to the rapid assembly of the heating wire and prevents the snap-fit ​​cover 140 from pressing the heating wire and causing the heating wire to break.

[0112] As another optional implementation, refer to Fig. 9, the heating device 120 is disposed between the flexible pad 130 and the transmission member 104, in other words, the heating device 120 is buried in the ore particles 150. In this case, refer to Fig.10 The separation rib 114 is preferably provided with a positioning groove 119 to allow the heating wire to be limited in the positioning groove 119. The heating wire is blocked by the positioning groove 119 to avoid collision with the ore particles 150 and damage.

[0113] Figures 11 to 17 FIG. 1 is a schematic diagram showing the installation process of the cover 100 according to an embodiment of the present application. Fig.11 As shown, firstly, the transmissive member 104 is assembled on the liner 102. Fig.12 , place the support frame 110 on the transmission member 104. Fig.13 , the ore particles 150 are laid in the support frame 110, and then refer to Fig.14 , scrape the ore particles 150 flat. Next, refer to Fig.15 , assemble the heating device 120 on the support frame 110, and then refer to Fig.16 , the flexible mat 130 is laid on the ore particles 150. Finally, refer to Fig.17 , the flexible pad 130 is pressed together using the snap-fit ​​cover 140 , and the snap-fit ​​cover 140 is assembled to the liner 102 .
