[0067] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings.

[0068] First embodiment

[0069] The cooking utensil of the present application generally comprises a pot body and a cover body 100. The pot body can be basically in the shape of a rounded rectangular parallelepiped, and the pot body 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. And the middle part of the middle plate has a cylindrical accommodating cavity, and the inner pot can be freely placed in the accommodating cavity or taken out from the accommodating cavity to facilitate the cleaning of the inner pot. The inner pot is generally made of metal material and has a circular opening on the upper surface for holding materials to be heated, such as rice, soup, etc. The pot body includes a heating device for heating the inner pot.

[0070] 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.

[0071] 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.

[0072] In addition, the cooking utensil may also have a temperature sensing device, such as an upper temperature sensing device disposed in the cover 100 and / or a lower temperature sensing device disposed below the inner pot accommodating cavity. The cooking utensil may also include a cover opening button mechanism, which is preferably disposed on the pot body and is connected to a locking mechanism that locks the cover 100 on the pot body through a transmission mechanism. When the cover opening button mechanism is pressed, the cover 100 can be automatically opened.

[0073] The cooking appliance includes a control device and a heating device. 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 device is used to heat the inner pot, and the heating device may be a coil disk. The control device is electrically connected to the heating device to achieve heating control.

[0074] The upper and lower temperature sensing devices are both electrically connected to the control device of the cooking appliance, so as to feed back the sensed temperature signal to the control device after sensing the temperature of the inner pot, so that the control device can achieve more accurate control of the cooking process based on the temperature signal. When the inner pot is placed in the inner pot accommodating cavity of the pot body, the lower temperature sensing device can sense the temperature of the bottom of the inner pot, for example, the lower temperature sensing device can be in direct or indirect contact with the bottom of the inner pot.

[0075] The specific structure of the cover 100 can be referred to Figures 1 to 8. Wherein, the cover body 100 includes a face cover 101, a lining 102, a support frame 110 and a removable cover 106. The lining 102 is arranged below the face cover 101 and connected to the face cover 101. The removable cover 106 is detachably arranged on the lining 102. The lining 102 is provided with a lining through hole 103, and the support frame 110 is arranged on the lining 102 and the position of the support frame 110 corresponds to the lining through hole 103. The support frame 110 is provided with an infrared radiator accommodating area 113 and an infrared radiation material accommodating area 114, an infrared emitter 122 is arranged in the infrared radiator accommodating area 113, and an infrared radiation material is arranged in the infrared radiation material accommodating area 114.

[0076] The infrared emitter 122 is configured to emit infrared rays when powered on. For example, the infrared emitter 122 may be an infrared emitting tube, which may excite infrared rays when powered on. The infrared radiation material may be configured to excite infrared rays when heated. Exemplarily, the infrared radiation material may include a plurality of mineral particles 150. Specifically, the mineral particles 150 may be tourmaline.

[0077] According to the cover of the present application, an infrared radiator is used to emit infrared rays to assist cooking. At the same time, the infrared rays can also heat the infrared radiation material, so that the infrared radiation material is heated and also stimulates infrared rays. The double infrared radiation further enhances the effect of assisting cooking, making the cooked food more delicious.

[0078] As a preferred embodiment, the cover body also includes a transmission member 104, which is arranged on the lining 102 to cover the lining through hole 103. The infrared radiator accommodating area 113 and the infrared radiation material accommodating area 114 are both constructed as through areas, and the support frame 110 is adjacently arranged on the upper side of the transmission member 104. In other words, the support frame 110 is placed on the upper surface of the transmission member 104. Therefore, when the infrared radiation material accommodating area 114 accommodates infrared radiation material, the infrared radiation material is carried by the transmission member 104. Such a setting simplifies the structure and assembly process, and the infrared rays emitted by the infrared radiator and the infrared radiation material can be radiated into the cooking cavity through the transmission member.

[0079] Specifically, refer to Figure 3 , Figure 4 and Figure 5 The support frame 110 includes an outer peripheral wall 111, an inner wall 112 and a fixed wall 115. The inner wall 112 is arranged inside the outer peripheral wall 111, and the fixed wall 115 is arranged on the outer peripheral surface of the outer peripheral wall 111. The support frame 110 is connected to the liner 102 through the fixed wall 115.

[0080] The inner wall 112 encloses an infrared radiator accommodating area 113, and an infrared radiation material accommodating area 114 is formed between the outer peripheral wall 111 and the inner wall 112. Preferably, the infrared radiator accommodating area 113 divides the infrared radiation material accommodating area 114 into at least two independent partitions. For example, in this embodiment, one infrared radiator accommodating area 113 separates two infrared radiation material accommodating areas 114. In this way, a structural form in which the infrared radiation material accommodating area 114 is outside and the infrared radiator accommodating area 113 is inside is formed, which is conducive to the infrared rays emitted by the infrared emitter 122 to irradiate the ore particles 150 as evenly as possible, and can also strengthen the restraint on the ore particles 150, further stabilizing the ore particles 150 and reducing the occurrence of shaking and the like.

[0081] refer to Figure 3 , Figure 4 and Figure 8 The cover 100 further includes a flexible pad 130, which is disposed in the infrared radiation material receiving area 114 to press the ore particles 150. The flexible pad 130 includes a pad body 131 and a plurality of synapses 132. The synapses 132 extend from the bottom side of the pad body 131 in a direction toward the transmission member 104, or in other words, the synapses 132 extend downward. The synapses 132 extend into the gaps between the ore particles 150, which can increase the contact points between the flexible pad 130 and the ore particles 150 and stabilize the ore particles 150.

[0082] In order to better fill the gap, the synapse 132 includes a columnar portion 133 and a spherical portion 134. The columnar portion 133 is connected to the pad body 131, and the spherical portion 134 is disposed at the end of the columnar portion 133. Preferably, the radial dimension of the spherical portion 134 is adapted to the radial dimension of the columnar portion 133.

[0083] The flexible pad 130 is arranged corresponding to the infrared radiation material receiving area 114. For example, in this embodiment, the infrared radiator receiving area 113 divides the infrared radiation material receiving area 114 into two parts, so two relatively independent flexible pads 130 are arranged. The shape of the flexible pad 130 is adapted to the shape of the corresponding infrared radiation material receiving area 114.

[0084] 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 8For 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°.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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, is satisfied. Such parameter setting enables the ore particle 150 to be stuck exactly between the two synapses 132 .

[0089] As a preferred embodiment, refer to Figure 1 , Figure 3 and Figure 7 The cover body 100 further includes a snap-on cover 140, which is disposed above the support frame 110 to close the laying space. Preferably, the bottom side of the snap-on cover 140 has a pressing rib 141 extending in a direction toward the flexible pad 130 or the transmissive member 104, and the pressing rib 141 abuts against the flexible pad 130. Thus, the flexible pad 130 can press the ore particles 150, thereby minimizing the possibility of the ore particles 150 shaking, displacing, and falling.

[0090] The snap-on cover 140 is preferably provided with a torsion spring positioning portion 142, which is used to limit the torsion spring arm of the cover opening torsion spring. For example, the first torsion spring arm can be fixed to the torsion spring positioning portion 142. In this way, one component has multiple functions, the integration of parts is improved, the space utilization rate is high, and the process is simplified, and the assembly efficiency is improved.

[0091] As an optional embodiment, the infrared emitter is arranged on the snap-fit ​​cover 140, and part of it extends into the infrared radiator accommodating area 113. Specifically, preferably, a reflective cover 121 is also arranged on the snap-fit ​​cover 140. The reflective cover 121 is specifically arranged on the lower side of the snap-fit ​​cover 140, and the infrared emitter 122 is arranged on the reflective cover 121, and the shape of the reflective cover 121 is adapted to the shape of the infrared emitter 122. As a result, the installation structure is simple and the space utilization rate is high, and the loss of infrared rays is small. In addition, the snap-fit ​​cover 140 can also act as a heat insulating member to reduce the influence of the infrared emitter 122 on other components on the upper side of the snap-fit ​​cover 140.

[0092] In this embodiment, the infrared emitter 122 is configured as a curved shape, for example, the infrared emitter 122 is configured as a transmitting tube in a U shape, a horseshoe shape, or a ring shape, etc. The infrared radiator receiving area 113 of the support frame 110 is also configured as a curved shape adapted to the infrared emitter 122, that is, the above-mentioned U shape, horseshoe shape, or a ring shape, etc.

[0093] like Figure 1 and Figure 2 As shown, the infrared emitting tube in this embodiment is a U-shaped tube, and the reflector 121 is also configured in a U-shape. Accordingly, the infrared radiator receiving area 113 of the support frame 110 is also configured in a U-shape. The gap between the two flexible pads 130 also needs to be configured in a corresponding U-shape.

[0094] Please refer to the following Figure 1 and Figure 4 , the transmission member 104 includes a transmission area 105. The transmission area 105 is configured as a transparent area to allow the transmission of infrared rays. Alternatively, the transmission area 105 is configured as a translucent area with color, thereby improving the visual effect. Optionally, the transmission area 105 is configured as a color-changing area, and the color-changing area is configured so that the color-changing area forms a transparent color or a translucent color when heated and / or illuminated, and the color-changing area forms an opaque color when not heated and not illuminated. In this way, the design sense can be further improved and the user experience can be optimized.

[0095] The above-mentioned transmission area 105 or the entire transmission member 104 may be made of glass.

The cover 200 of the second preferred embodiment has a similar structure and / or construction to the cover 100 of the first preferred embodiment, except for the shape of the infrared emitter 222 and related structures. Therefore, elements having substantially the same functions as those in the first embodiment will be numbered the same here, and will not be described and / or illustrated in detail for the sake of brevity.

[0098] In this embodiment, the infrared emitter 222 is constructed in a straight line shape, such as the "I"-shaped infrared tube described in the figure. The infrared radiator storage area 213 of the support frame 210 is also constructed in a curved shape that is compatible with the infrared emitter 222, that is, the "I" shape described above.

[0099] The reflector 221 is also constructed in a straight line shape. Correspondingly, the infrared radiator receiving area 213 of the support frame 210 is also constructed in a straight line shape. At the same time, the shapes of the reflector 221, the transmission member 204, the flexible pad 230, etc. also need to be designed adaptively.
