[0080] It should be noted that the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside" and similar expressions used in this document are for illustrative purposes only and are not limiting.

[0081] Now, exemplary embodiments according to the present utility model will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present utility model thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0082] The utility model provides a cooking utensil, which comprises a pot body and a cover body. The pot body has a cylindrical inner pot storage part. The inner pot can be fixedly arranged at the inner pot storage part, or can be freely placed in the inner pot storage part or taken out from the inner pot storage part to facilitate the cleaning of the inner pot. The inner pot is usually 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, such as a heating plate, to heat the inner pot.

[0083] It can be understood that the cooking utensil according to the present invention can be an electric rice cooker, an electric pressure cooker or other cooking utensil, and the cooking utensil can have various functions such as cooking porridge in addition to the function of cooking rice.

[0084] The cover has a shape that is substantially corresponding to the pot body. The cover can be opened and closed on the pot body. Specifically, it is pivotally connected to the pot body through 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 the closing and opening of the pot body. When the cover is closed on the pot body, it covers the inner pot and forms a cooking space between the inner pot and the cover. The cover is usually also provided with a pot mouth sealing ring, which can be made of, for example, a rubber material, and is arranged between the cover and the inner pot to seal the cooking space when the cover is in the closed state.

[0085] Figures 1 to 6 The structure of the cover body 1 of the present invention is schematically shown. Figure 1 and Figure 2 As shown, the cover body 1 may include an inner liner 2, a face cover assembly 3 located on the upper side or the outer side of the inner liner 2, and a removable cover assembly 4 located on the lower side or the inner side of the inner liner 2. The face cover assembly 3 may be connected to the inner liner 2 in any suitable manner such as by fastening, snapping, plugging, etc. with fasteners such as screws. For example, the face cover assembly 3 may be snapped with the outer periphery of the inner liner 2 by a snap-fit ​​structure. The removable cover assembly 4 may be detachably mounted to the inner liner 2 by snapping, so that the removable cover assembly 4 can be removed for cleaning.

[0086] It should be noted that the directional terms used in this article to describe the various components and parts of the cover body 1, such as "up", "down", "above", "below", "upward", "downward", "upward", "downward", etc., are relative to the cover body 1 in a horizontally placed and closed state.

[0087] The removable cover assembly 4 includes a radiation plate 41, which is used to radiate infrared rays to the cooking space after being heated. In order to heat the radiation plate 41, the cover body 1 also includes a cover heating device 5. The cover heating device 5 is arranged on the upper side of the removable cover assembly 4, specifically between the lining 2 and the removable cover assembly 4. The radiation plate 41 is heated by the cover heating device 5, so that the radiation plate 41 radiates infrared rays to the cooking space during the cooking process, which can improve the heat utilization efficiency, effectively heat the food, make the food heated evenly, stimulate the aroma of the food, and make the food more delicious; the radiation plate 41 can also generate infrared rays to keep the food warm after the cooking process.

[0088] In this article, the radiation plate 41 is arranged on the removable cover assembly 4, so that the radiation plate 41 can be closer to the food in the inner pot, and the radiation distance of the infrared rays reaching the food is shortened to a certain extent. By shortening the radiation distance, the heat radiation intensity and efficiency can be improved to a certain extent, energy loss can be avoided, and the effect of heating food can be better.

[0089] At least part of the bottom surface of the radiation plate 41 constitutes a part of the top surface of the cooking space; in other words, the bottom surface of the radiation plate 41 is exposed to the cooking space. The steam generated during the cooking process will directly contact the bottom surface of the radiation plate 41. Since the radiation plate 41 has a higher temperature due to the cover heating device 5, it can effectively prevent condensation from being generated on its bottom surface or volatilize the generated condensation, thereby preventing the condensation from flowing back and affecting the taste of the food.

[0090] The material of the radiation plate 41 is food contact grade. The material of the radiation plate 41 is one or more of graphene, biochar, carbide, metal oxide and infrared ceramic. Optionally, the radiation plate 41 is a ceramic element. The cover heating device 5 can raise the temperature of the ceramic element to a preset temperature, for example, the preset temperature can be 80°C to 300°C, to radiate infrared rays with a main wavelength of 2μm to 14μm to assist in cooking food.

[0091] In order to avoid a gap between the radiation plate 41 and the cover heating device 5, the cover body 1 further includes an elastic component 6, and the cover heating device 5 can change its position in the up and down direction. The elastic component 6 is located between the lining 2 and the cover heating device 5. Thus, the elastic component 6 can provide an elastic force toward the radiation plate 41 to the cover heating device 5, so that the cover heating device 5 contacts the radiation plate 41. In this way, the cover heating device 5 can be elastically arranged on the cover body 1 through the elastic component 6. When the removable cover assembly 4 is installed to the cover body 1, the radiation plate 41 can contact the cover heating device 5 and push the cover heating device 5 to move upward or away from the pot body. After the removable cover assembly 4 is installed, due to the presence of the elastic force, the radiation plate 41 maintains contact with the cover heating device 5. As a result, the heat of the cover heating device 5 can be efficiently transferred to the radiation plate 41, shortening the time for the radiation plate 41 to heat up and improving the heating efficiency of the radiation plate 41. And due to the presence of the elastic force, the driving force of the radiation plate 41 on the cover heating device 5 is small, which can avoid damage to the radiation plate 41 and the cover heating device 5.

[0092] If necessary and / or desired, when the removable cover assembly 4 is installed, the radiation plate 41 does not push the cover heating device 5; when the removable cover assembly 4 is installed, the radiation plate 41 just contacts the cover heating device 5.

[0093] The cover heating device 5 can be movably connected to the liner 2. The elastic component 6 can be sandwiched between the liner 2 and the cover heating device 5, or connected to the liner 2 and / or the cover heating device 5. This solution allows the cover heating device 5 to be elastically connected to the liner 2, the structure of the cover body 1 is simple, and the number of internal components is small.

[0094] Specifically, the cover heating device 5 includes a heating element 51 and a heat-conducting baffle 52. The heat-conducting baffle 52 is located at the lower side of the heating element 51 and contacts the radiation plate 41. The heat generated by the heating element 51 can be efficiently transferred to the radiation plate 41 through the heat-conducting baffle 52. The heat-conducting baffle 52 can shield the heating element 51 to prevent the heating element 51 from being exposed when the detachable cover assembly 4 is removed, so as to avoid the risk of electric shock caused by the user contacting the heating element 51, and to prevent liquids such as water from accidentally splashing onto the heating element 51 and causing damage to the heating element 51.

[0095] The heating element 51 is made of metal. The heating element 51 can be an electric heating element such as a heating wire, a heating sheet, or a heating layer. The heating layer is formed of a conductive material such as graphite, and can be set on the heat-conducting baffle 52 by silk-screen printing or the like. Of course, the specific structure of the heating element 51 is not limited and can be set arbitrarily as needed. The heat-conducting baffle 52 is generally a metal component with good thermal conductivity. Of course, it can also be a non-metal component made of a heat-conducting material such as a heat-conducting rubber.

[0096] The outer periphery of the heat-conducting baffle plate 52 is provided with an upwardly extending baffle plate outer peripheral wall 53, and the heating element 51 is located in the area surrounded by the baffle plate outer peripheral wall 53. Therefore, the heat-conducting baffle plate 52 can also shield the heating element 51 on the outer periphery side, and the heating element 51 will not be exposed when the cover heating device 5 moves; and when the detachable cover assembly 4 is not installed, it can avoid that the gap between the heat-conducting baffle plate 52 and the liner 2 is too large, which affects the user's perception.

[0097] The heat-conducting baffle 52 can be movably connected to the liner 2, and the heating element 51 is fixed to the heat-conducting baffle 52. The heating element 51 is supported by the heat-conducting baffle 52 and is installed on the liner 2 through the heat-conducting baffle 52. This solution reduces the number of components of the cover heating device 5, and the internal structure of the cover body 1 is simple, which is easy to manufacture. The heating element 51 and the heat-conducting baffle 52 form a whole, and when assembled, they are installed to the liner 2 in an integral manner, which has high assembly efficiency.

[0098] like Figures 3 to 5 As shown, the heat-conducting baffle 52 is provided with an upwardly extending mounting post 54, and the elastic component 6 is sleeved on the mounting post 54 and abuts against the liner 2. The mounting post 54 can guide and limit the elastic component 6, so that the elastic component 6 can shrink and stretch more smoothly, and maintain the elastic support effect on the radiation plate 41. In this solution, the elastic component 6 can be a spring, such as a metal coil spring or a rubber coil spring; alternatively, the elastic component 6 can be an elastic block made of an elastic material such as rubber. The number of elastic components 6 can be greater than or equal to 2, and the mounting posts 54 are dispersedly arranged on the heat-conducting baffle 52. The mounting posts 54 correspond to the elastic components 6 one by one. The illustrated embodiment shows three elastic components 6 and three mounting posts 54.

[0099] In the illustrated embodiment, the cover body 1 includes a threaded fastener (not shown), and the liner 2 is provided with a mounting hole 21, and the mounting hole 21 corresponds to the position of the mounting column 54. The fastener can pass through the mounting hole 21, and the lower end of the fastener is threadedly connected to the mounting column 54, and the upper end of the fastener is provided with a stop structure so as to be movably connected with the liner 2. When the heat-conducting baffle 52 moves upward, the fastener moves with the heat-conducting baffle 52, and the stop structure is disengaged from the upper surface of the liner 2; when the removable cover assembly 4 is not installed, the stop structure abuts against the upper surface of the liner 2 to prevent the heat-conducting baffle 52 from being disengaged from the liner 2. The mounting column 54 in this solution can be used to limit the elastic component 6, and can also be used to make the heat-conducting baffle 52 movably connected, which is a dual purpose, simplifies the structure of the cover heating device 5, and is conducive to the production and manufacturing of the cover heating device 5. In addition, the fastener fixing method has a simple structure and is convenient for production and manufacturing.

[0100] Optionally, the stop structure includes a nut and a thread on the upper end of the fastener, and the nut is connected to the upper end of the fastener through the thread. The position of the nut on the fastener can be set as needed. Alternatively, the stop structure can be a head integral with the fastener, such as a single-head bolt.

[0101] In other embodiments not shown, the heat-conducting baffle 52 is provided with a connecting buckle extending upward, and the liner 2 is provided with a mounting hole 21, and the mounting hole 21 corresponds to the position of the connecting buckle. Optionally, the connecting buckle is provided on the outer peripheral wall 53 of the baffle. The upper end of the connecting buckle can extend upward from the mounting hole 21 and bend horizontally so as to be movably connected with the liner 2. When the heat-conducting baffle 52 moves upward, the bent portion of the connecting buckle is separated from the upper surface of the liner 2; when the removable cover assembly 4 is not installed, the bent portion of the connecting buckle abuts against the upper surface of the liner 2 to prevent the heat-conducting baffle 52 from being separated from the liner 2. In addition, the method of fixing the connecting buckle is simple in structure, easy to assemble, and convenient for production and manufacturing.

[0102] Optionally, an elastic sealing ring may be provided between the outer periphery of the heat-conducting baffle 52 and the liner 2, and the elastic sealing ring serves as the elastic component 6. Thus, the gap between the heat-conducting baffle 52 and the liner 2 can be sealed to prevent liquid such as water from accidentally flowing into the heating element 51 and causing damage to the heating element 51.

[0103] In this embodiment, there are several ways to set the elastic component 6: one example is that no elastic sealing ring is provided, and the elastic component 6 includes an elastic component 6 sleeved on the mounting column 54. Another example is that an elastic sealing ring is provided, and the elastic component 6 includes an elastic component 6 sleeved on the mounting column 54 and an elastic sealing ring. Another example is that the elastic component 6 sleeved on the mounting column 54 is not provided, and the elastic component 6 includes an elastic sealing ring.

[0104] For the heat-conducting baffle 52 of the metal component, the cover body 1 also includes a grounding wire, which is connected to the heat-conducting baffle 52. The grounding wire can be directly connected to the mounting column 54 or the main body of the heat-conducting baffle 52. The grounding wire can be connected at the connection between the fastener and the mounting column 54. Alternatively, the main body of the heat-conducting baffle 52 is provided with a plug-in structure, and the grounding wire is plugged into the heat-conducting baffle 52 through the plug-in structure. By setting the grounding wire, grounding protection can be provided for the heating device. When the electrically heated heating element 51 generates an unexpected leakage phenomenon, the leakage current is prevented from flowing to the radiation plate 41 through the heat-conducting baffle 52, thereby avoiding the existence of current on the bottom surface of the radiation plate 41. As a result, if the user touches the bottom surface of the radiation plate 41 after opening the cover, there will be no risk of electric shock. The product provided in this embodiment is highly safe and can meet the safety requirements of the product.

[0105] The cover 1 includes a wire, and the terminal of the heating element 51 is electrically connected to the control board through the wire so as to work in an electronically controlled manner. Figure 4As shown, the lining 2 is provided with a wire hole 22, and the wire can be routed through the wire hole 22 and connected to the heating element 51. The lining 2 is generally made of plastic material, and the wire hole 22 is easy to form, which is convenient for the production and manufacture of the cover body 1.

[0106] like Figure 3 As shown, the liner 2 is provided with a mounting groove 23 with the notch facing downward, and the cover heating device 5 and the elastic component 6 are at least partially located in the mounting groove 23. The side wall of the mounting groove 23 can limit the horizontal position of the cover heating device 5 and provide guidance for the movement of the cover heating device 5 in the up and down directions. Figure 4 As shown, the liner 2 includes a liner body 24 and a mounting portion 25 having a mounting groove 23. The mounting portion 25 can protrude upward from the upper surface of the liner body 24. The cover heating device 5 can be effectively arranged in the middle space of the cover body 1, which is conducive to reducing the size of the cover body 1 in the up and down directions.

[0107] like Figure 6 As shown, the removable cover assembly 4 also includes a hollow support frame 42, a fixing member 43 and a pot mouth sealing ring 44. The support frame 42 is used to detachably connect the removable cover assembly 4 to the liner 2. The support frame 42 is arranged on the outer periphery of the radiation plate 41 and supports the radiation plate 41 upward. The fixing member 43 is located on the upper side of the radiation plate 41 and is connected to the support frame 42. For example, the fixing member 43 is provided with a mounting foot 45 extending downward, and the mounting foot 45 can be fixed to the support frame 42 by bending, clamping, etc. The fixing member 43 is annular.
