[0082] 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.

[0083] The preferred embodiment of the present invention provides a cooking utensil, which comprises a pot body and a cover body 1 (such as Figure 1 As shown in FIG. 1 ). The pot body has a cylindrical inner pot storage portion. The inner pot can be fixedly arranged at the inner pot storage portion, or can be freely placed in or taken out of the inner pot storage portion to facilitate 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.

[0084] 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.

[0085] The cover 1 has a shape that is substantially corresponding to the pot body. The cover 1 can be opened and closed on the pot body. Specifically, it 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 the closing and opening of the pot body. When the cover 1 is closed on the pot body, it covers the inner pot and forms a cooking space between the inner pot and the cover 1. The cover 1 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 1 and the inner pot to seal the cooking space when the cover 1 is in the closed state.

[0086] Figures 1 to 4 The cover body 1 of the preferred embodiment of the utility model is schematically shown. Figure 1 and Figure 2 As shown, the cover body 1 may include a liner 10, a face cover assembly 20 located on the upper side or outer side of the liner 10, and a removable cover assembly 30 located on the lower side or inner side of the liner 10. The face cover assembly 20 may be mounted to the liner 10 by other suitable means such as snaps or fasteners. The removable cover assembly 30 may be removably mounted to the liner 10 by other suitable means such as snaps or fasteners, so as to facilitate the removal of the removable cover assembly 30 for cleaning.

[0087] 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.

[0088] The removable cover assembly 30 may include a removable cover 31, an annular removable cover seat 32, and the pot mouth sealing ring 36. The removable cover seat 32 can detachably connect the removable cover 31 and the pot mouth sealing ring 36 to the liner 10. The removable cover 31 can be connected to the removable cover seat 32 by other suitable means such as snap fastening or fastener fastening, and the pot mouth sealing ring 36 is pressed against the removable cover 31.

[0089] The cover 1 further includes an infrared heating assembly 40, which is used to radiate infrared rays, such as far infrared rays, to the cooking space. The infrared heating assembly 40 radiates infrared rays to the cooking space during the cooking process, which can improve the heat utilization efficiency, effectively heat the food, heat the food evenly, stimulate the aroma of the food, and make the food more delicious; the infrared heating assembly 40 can also generate infrared rays to keep the food warm after the cooking process.

[0090] The infrared heating assembly 40 may include a heating element 41 and an isolating member 42. The heating element 41 can work when powered on. The isolating member 42 can isolate the heating element 41 from the cooking space, isolate and protect the heating element 41, and avoid the risk of electric shock caused by the user directly touching the heating element 41 when the cover 1 is opened.

[0091] The lower surface of the isolating member 42 can be at least partially exposed to the cooking space, so that the steam generated during the cooking process can directly contact the lower surface of the isolating member 42. Since the isolating member 42 has a relatively high temperature due to the action of the heating element 41, it can effectively prevent condensation from being generated on its lower surface or volatilize the generated condensation, thereby preventing the condensation from flowing back and affecting the taste of the food.

[0092] In one example, the isolating member 42 may be configured as a ceramic element, which is used to radiate infrared rays to the cooking space after being heated. The heating element 41 is used to heat the ceramic element, for example, by heating it at a preset power or a preset temperature, so that the ceramic element is heated and radiates infrared rays to the cooking space. Furthermore, the heating power or heating temperature of the heating element 41 may be controlled, thereby controlling the temperature of the ceramic element to suit respective cooking conditions. In this solution, the heating element 41 may be a heating layer, a heating wire, etc.

[0093] After being heated, the ceramic element can radiate infrared rays of various wavelengths to the cooking space, and thus can also be called an infrared ceramic element. The main wavelength of infrared rays is 2μm to 14μm, for example, 2μm, 4μm, 6μm, 8μm, 10μm, 12μm, 14μm, etc. The heating element 41 can raise the temperature of the ceramic element to a preset temperature, for example, the preset temperature can be 80℃ to 300℃, to radiate infrared rays with a main wavelength of 2μm to 14μm to assist in cooking food. The wiring terminal of the heating element 41 is electrically connected to the control board through a wire so as to work in an electrically controlled manner.

[0094] During the cooking process, ceramic elements radiate infrared rays with a main wavelength of 2μm to 14μm into the cooking space, which can improve the heat utilization efficiency, effectively heat the food, heat the food evenly, stimulate the aroma of the food, and make the food more delicious; ceramic elements can also generate infrared rays to keep the food warm after the cooking process.

[0095] Furthermore, since the ceramic element itself is relatively hard and not easily damaged, it can be at least partially exposed to the cooking space without any additional isolation and protection components. Thus, the number of components in the cover body 1 can be reduced, the structure of the cover body 1 can be simplified, and the cost is low.

[0096] In addition, the ceramic element can generate infrared rays by generating heat, and its own temperature is relatively high, which can effectively prevent condensation from forming on its lower surface or evaporate the condensation that has already formed, thereby preventing the condensation from flowing back and affecting the taste of food.

[0097] In other alternative examples, the heating element 41 is configured as an infrared heating element, which generates infrared rays by self-heating. The isolator 42 is at least partially made of a light-transmitting material so that the infrared rays generated by the infrared heating element are radiated to the cooking space. The isolator 42 is light-transmitting as a whole, or the part of the isolator 42 corresponding to the infrared heating element is light-transmitting. The light-transmitting material may include glass or light-transmitting plastic, for example, transparent tempered glass, silicon glass, germanium glass, light-transmitting PC (Polycarbonate), etc. Optionally, the infrared heating element may be made of a carbon-containing material, for example, a carbon component, one example of which is a carbon fiber component, or a carbon coating, one example of which is a carbon fiber coating.

[0098] The heating element 41 is disposed on the portion of the isolating member 42 except for the lower surface thereof. The heating element 41 is disposed above the isolating member 42. The arrangement method can be selected arbitrarily as required, for example, the heating element 41 is laid on the isolating member 42. In one example, for example Figure 3As shown, the heating element 41 is laid on the upper surface of the isolation member 42. In another alternative example, the isolation member 42 forms a hollow cavity, and the heating element 41 is laid in the hollow cavity. By supporting and fixing the heating element 41 with the aid of the isolation member 42, the isolation member 42 and the heating element 41 can be arranged more compactly, the internal space utilization rate of the cover body 1 can be improved, and the product miniaturization is facilitated. The isolation member 42 can be plate-shaped, or it can be formed into other structures other than plate-shaped.

[0099] like Figure 2 As shown, the liner 10 is provided with a liner opening 11. The spacer 42 is installed at the liner opening 11. The removable cover 31 is arranged below the spacer 42. The removable cover 31 can be partially provided with a removable cover opening 33. The removable cover opening 33 corresponds to the position of the spacer 42. In other words, the removable cover opening 33 is located directly below the spacer 42. Infrared rays can be radiated toward the inner pot 2 via the liner opening 11 and the removable cover opening 33.

[0100] In order to better fix the isolation member 42, as Figure 2 As shown, the liner 10 may be provided with a support portion 12. The support portion 12 is arranged around the liner opening 11, and the support portion 12 forms a closed annular structure. The outer periphery of the isolating member 42 can overlap the support portion 12, for example, overlap the bottom wall of the support portion 12 and abut against the side wall of the support portion 12. Thus, the support portion 12 can provide an upward support force to the isolating member 42, and limit the movement of the isolating member 42 in the horizontal direction, so as to facilitate the fixing of the isolating member 42.

[0101] The cover body 1 may further include a sealing ring. Specifically, the removable cover 31 includes an opening edge portion 38 that forms a removable cover opening 33. The sealing ring is disposed at least one of the opening edge portion 38 and the support portion 12 to form a seal at least between the spacer 42 and the removable cover 31 to prevent steam from entering the interior of the cover body 1 from the gap therebetween, thereby improving the sealing effect of the cover body 1. An example is that the sealing ring is disposed at the opening edge portion 38 and is in interference fit with the spacer 42; an alternative example is that the sealing ring is disposed at the support portion 12 and is in interference fit with both the spacer 42 and the removable cover 31, specifically, in interference fit with the outer periphery of the spacer 42 and the opening edge portion 38.

[0102] In the illustrated embodiment, the cover body 1 includes a first sealing ring 52. The first sealing ring 52 can be disposed at the opening edge portion 38. The first sealing ring 52 is disposed at least between the opening edge portion 38 and the isolation member 42. The illustrated embodiment schematically shows that the first sealing ring 52 is fixed to the removable cover 31, and its upper end abuts against the isolation member 42; for example, Figure 3As shown, the first sealing ring 52 can be fixed to the removable cover 31 by a pressing member 54, through holes are provided at intervals between the pressing member 54 and the first sealing ring 52, and the removable cover 31 is provided with clamping feet at intervals, which pass through the through holes of the pressing member 54 and the first sealing ring 52 and then bend. In this way, the gap between the isolation member 42 and the removable cover 31 can be sealed to prevent steam from entering the interior of the cover body 1 through these gaps, thereby improving the sealing effect of the cover body 1. The first sealing ring 52 is made of a flexible and elastic material as a whole.

[0103] The cover body 1 may further include a second sealing ring 53. The second sealing ring 53 can be arranged at the edge of the liner opening 11. Specifically, the second sealing ring 53 is at least arranged between the support portion 12 and the isolating member 42. The second sealing ring 53 can be fixed to the support portion 12 or the isolating member 42. The illustrated embodiment schematically shows that the second sealing ring 53 is sleeved to the outer periphery of the isolating member 42, for example, the second sealing ring 53 is provided with a mounting groove with an opening toward the center thereof, and is sleeved on the outer periphery of the isolating member 42 through the mounting groove. In this way, the gap between the isolating member 42 and the liner 10 can be sealed to prevent steam from entering the interior of the cover body 1 from these gaps, thereby improving the sealing effect of the cover body 1.

[0104] Return to see Figure 1 , the cover body 1 may be provided with a steam channel structure 60, which is arranged at the rear of the cover body 1. The steam channel structure 60 forms a steam channel extending in the vertical direction. Specifically, the steam channel structure 60 may include a steam valve 61, a steam channel wall 62 and a steam channel seal 63. The steam valve 61 is provided on the face cover assembly 20. The steam channel wall 62 extends in the vertical direction and is located between the face cover assembly 20 and the liner 10. The steam channel wall 62 encloses a steam channel, and the steam channel seal 63 is provided with a penetrating steam channel.

[0105] In order to prevent condensation on the removable cover 31 due to the relatively low temperature of the removable cover 31 during cooking, the removable cover 31 of this embodiment is integrally formed with a heat conducting portion 80. It can be understood that the heat conducting portion 80 has good heat conducting properties and can effectively transfer heat. The heat conducting portion 80 protrudes toward the isolation member 42. Figure 4 As shown, the top surface of the heat conductive portion 80 can contact or be close to the isolation member 42 , so that the heat of the isolation member 42 is transferred to the removable cover 31 .

[0106] In this embodiment, when the cooking utensil is used for cooking, the heat conducting part 80 can effectively transfer the heat of the isolating member 42 to the removable cover 31, so that the temperature of the removable cover 31 is kept at a high level, and condensation water is prevented from being generated on the removable cover 31 and falling onto the food. In this way, the taste of the food will be better, and the user experience will be improved.

[0107] The heat conducting part 80 can be arranged around the removable cover opening 33. The heat conducting part 80 corresponds to the low temperature area of ​​the removable cover 31, and the heat conducting part 80 can transfer heat to the removable cover 31 at various positions on the circumference of the removable cover 31. The temperature of the part of the removable cover 31 exposed to the cooking space can be increased, and condensation water on the removable cover 31 can be more effectively avoided. The removable cover 31 is made of metal material, so that the metal heat conducting part 80 has better thermal conductivity and better thermal conductivity efficiency.

[0108] The width W of the cross section of the heat conducting portion 80 at the top surface is 2 mm ≤ W, for example, W may be 2 mm, 2.2 mm, 2.5 mm, 2.8 mm, 3 mm, 3.2 mm, 3.5 mm, etc. The distance D between the heat conducting portion 80 and the isolation member 42 is 0 mm ≤ D ≤ 5 mm, for example, D may be 0 mm, 0.5 mm, 1.0 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 4 mm, 5 mm, etc. The smaller the distance D, the easier it is to conduct heat.

[0109] The heat conducting portion 80 is disposed discontinuously or continuously along the removable cover opening 33. In the illustrated embodiment, as shown in FIG. Figure 5 As shown, the heat conducting portion 80 is continuously disposed along the removable cover opening 33 , and the heat conducting portion 80 is configured in an open loop shape or a closed loop shape extending along a predetermined loop line. Figure 5 The heat conducting part 80 is shown to be an arc-shaped open loop, so that the heat conducting efficiency is high, the heat can be effectively transferred, the structure is simple, and the production and assembly are convenient.

[0110] In other embodiments not shown, the heat conducting portion 80 is intermittently arranged along the removable cover opening 33 to form a multi-stage structure. Specifically, the heat conducting portion 80 is configured as a plurality of portions spaced apart along a predetermined annular line. Each portion may be in any suitable shape such as a dot or strip. Thus, the heat conducting efficiency is high, heat can be effectively transferred, material usage is reduced, and material cost is reduced.

[0111] like Figures 4 to 7 As shown, the removable cover 31 includes a cover body 37 and an opening edge 38 forming an opening of the removable cover. The cover body 37 is connected to the opening edge 38. The heat conducting portion 80 may be formed in at least one of the cover body 37 and the opening edge 38. The cover body 37 and the opening edge 38 constitute a low temperature area of ​​the removable cover 31 corresponding to the cooking space, and either or both of the cover body 37 and the opening edge 38 may be formed with the heat conducting portion 80, so as to realize the transfer of heat from the isolation member 42 to the removable cover 31, and the product has a large degree of freedom in design.

[0112] In one embodiment, if Figures 4 to 6As shown, the heat conducting portion 80 can be formed on the cover body 37. For example, a portion of the cover body 37 is bent toward the spacer 42 to form the heat conducting portion 80, and the heat conducting portion 80 has a double-sided bending structure. By bending a portion of the cover body 37 to form the heat conducting portion 80, the heat of the spacer 42 can be transferred to the cover body 37. The bending method makes the structure of the removable cover 31 simple and easy to manufacture.

[0113] The heat-conducting portion 80 may include a heat-conducting top wall 81 and two heat-conducting side walls 82 arranged opposite to each other. The heat-conducting top wall 81 is connected to the two heat-conducting side walls 82, respectively, and the heat-conducting top wall 81 may contact or be close to the isolation member 42. At least one of the two heat-conducting side walls 82 is a straight wall, an inclined wall, or an arc-shaped wall extending vertically. The two heat-conducting side walls 82 have the same structure, and are both straight walls, or are both inclined walls, or are both arc-shaped walls. Alternatively, the structures of the two heat-conducting side walls 82 are different, and one of the two heat-conducting side walls 82 is one of a straight wall, an inclined wall, and an arc-shaped wall, and the other of the two heat-conducting side walls 82 is the remaining one of a straight wall, an inclined wall, and an arc-shaped wall.

[0114] An example is, Figure 4 As shown, the two heat-conducting side walls 82 are straight walls, and together with the heat-conducting top wall 81, form a groove with an opening facing downward and equal width. Thus, it is possible to avoid liquid accumulation in the groove of the heat-conducting portion 80 when the removable cover 31 is removed for cleaning.

[0115] In an optional example, at least one of the two heat-conducting side walls 82 is an inclined wall, and the two heat-conducting side walls 82 extend from bottom to top close to each other and the bottoms of the two are spaced apart. Figure 6 It is schematically shown that both heat-conducting side walls 82 are inclined walls, extending from bottom to top close to each other and the bottoms of the two are spaced apart. Alternatively, one of the two heat-conducting side walls 82 may be an inclined wall and the other may be a straight wall, and the inclined wall may extend from bottom to top close to the straight wall and the bottoms of the two may be spaced apart. The two heat-conducting side walls 82 together with the heat-conducting top wall 81 form a groove with an opening facing downward and gradually widening. In this way, not only can the accumulation of liquid in the groove of the heat-conducting portion 80 be avoided when the removable cover 31 is removed for cleaning; and if there is foreign matter in the groove of the heat-conducting portion 80, the inclined wall can facilitate the cleaning of the foreign matter.

[0116] Another optional example is that at least one of the two heat-conducting side walls 82 is an inclined wall, and the two heat-conducting side walls 82 extend away from each other from bottom to top and the bottoms of the two are sealed. The bottom seal can be formed by setting a seal or a sealant. For example, both heat-conducting side walls 82 are inclined walls, extending away from each other from bottom to top and the bottoms of the two are sealed. Alternatively, one of the two heat-conducting side walls 82 is an inclined wall, and the other is a straight wall, and the inclined wall extends away from the straight wall from bottom to top and the bottoms of the two are sealed.

[0117] Another optional example is that the two heat-conducting side walls 82 are inclined walls with the same inclination direction.

[0118] In another embodiment, Figure 7 As shown, at least the opening edge portion 38 is bent toward the spacer 42 to form a heat conducting portion 80, and the heat conducting portion 80 has a single-side bent structure. By bending at least the opening edge portion 38 to form the heat conducting portion 80, the heat of the spacer 42 can be transferred to at least the opening edge portion 38. Figure 7 It is shown that a part of the cover body 37 and the opening edge 38 are both bent. In this embodiment, the first sealing ring 52 may not be provided at the opening edge 38, and the second sealing ring 53 at the support portion 12 can form a seal between the isolation member 42 and the removable cover 31. Specifically, the second sealing ring 53 has a sealing portion extending downward, and the sealing portion abuts against the removable cover 31.

[0119] The opening edge of the opening edge portion 38 is bent upward to form a curling edge 50. By providing the curling edge 50, the opening edge of the removable cover 31 is gentle and not sharp, which can prevent the operator from scratching during disassembly and assembly. The opening edge portion 38 forms a sinking structure 51 at the curling edge 50, so that the portion of the opening edge portion 38 outside the curling edge 50 contacts or is closer to the isolation member 42. With the sinking structure 51, the formed heat conducting portion 80 can contact or be closer to the isolation member 42. Of course, the curling edge 50 can contact or be closer to the isolation member 42. Figure 7 It is schematically shown that the opening edge is bent upward by 180° to form a horizontally extending curling edge 50 .

[0120] Return to see Figure 2 , the heating element 41 is fixed to the upper surface of the isolating member 42 or embedded in the interior of the isolating member 42. In the illustrated embodiment, the heating element 41 is laid on the upper surface of the isolating member 42. The heating element 41 can be laid in a manner of being attached to the upper surface of the isolating member 42, or at least partially embedded in the upper surface of the isolating member 42. Schematically, for example, the heating element 41 can be bonded to the upper surface of the isolating member 42 by any suitable means such as tape, adhesive, etc. Of course, the heating element 41 can also be connected to the upper surface of the isolating member 42 by other means.

[0121] In the solution of ceramic elements, the heating element 41 is generally made of metal. The illustrated embodiment schematically shows that the heating element 41 is configured as a filament, in other words, the heating element 41 is a heating wire. The filamentary heating element 41 can be laid in a single winding or in a plurality of windings in series or in parallel. In other embodiments not shown, the heating element 41 can be configured as a sheet, such as a metal sheet, and the sheet-like heating element 41 is laid horizontally. The heating element 41 can be configured as a heating layer formed on the upper surface of the insulating member 42. The heating layer is formed of a conductive material such as graphite, for example, and can be provided on the insulating member 42 by means of silk screen printing or the like. Of course, the specific structure of the heating element 41 is not limited and can be arbitrarily set as needed.

[0122] The removable cover 31 is provided with a steam port 35. The removable cover 31 may be provided with a protrusion 34 protruding toward the center of the removable cover opening 33. The protrusion 34 is formed with a steam port 35 communicating with the steam channel structure 60.

[0123] In an embodiment not shown, the isolating member 42 may be provided with an avoidance gap. The heat conducting portion 80 is separated by the steam port 35. This solution can reduce the amount of ceramic material while increasing the radiation area of ​​infrared rays, can reduce production costs, and the processing technology of the isolating member 42 is simple. The heat conducting portion 80 has a larger heat transfer area and can transfer more heat.

[0124] In another embodiment, such as the illustrated embodiment, the isolating member 42 may be provided with an avoidance through hole 43. The steam channel structure 60 may be provided through the avoidance through hole 43. The heat conducting portion 80 is blocked by the steam port 35. The isolating member 42 has a large infrared radiation area, and the processing technology of the isolating member 42 is simple. The heat conducting portion 80 has a large heat transfer area for heat, and can transfer more heat.

[0125] In another embodiment not shown, the spacer 42 is circular and has no through hole. The steam channel structure 60 is located on one side of the spacer 42, specifically the rear side. The heat conducting portion 80 is located radially inward of the center of the steam port 35 close to the cover body 1 and is continuously arranged at a position corresponding to the steam channel structure 60. In this solution, the spacer 42 is not penetrated by the steam channel structure 60 and is of a standard shape. The structure of the spacer 42 is simple and convenient for production and manufacturing.

[0126] Alternatively, the removable cover 31 is not provided with a steam port. The isolating member 42 is provided with an avoidance through hole 43 or an avoidance notch for the steam channel structure 60 to pass through. In horizontal projection, the projection of the avoidance through hole 43 or the avoidance notch falls inside the projection of the opening edge portion 38. The steam channel seal 63 forms a seal at the avoidance through hole 43 or the avoidance notch. The projection of the heat conducting portion 80 falls outside the projection of the opening edge portion 38, that is, the heat conducting portion 80 is located radially outside the opening edge portion 38.

[0127] The cover body 1 also includes a fixing member 70, which is located above the isolation member 42 and presses down the isolation member 42. The fixing member 70 includes a mounting portion 71 and a pressing portion 72. The mounting portion 71 is detachably connected to the liner 10, for example, the liner 10 is provided with a fixing portion 13 at intervals, and the mounting portion 71 is detachably connected to the fixing portion 13. The illustrated embodiment schematically shows that the fixing member 70 is fixed to the liner 10 by fasteners such as screws, the mounting portion 71 is provided with a screw hole, the fixing portion 13 is configured as a screw column, the screw column is connected to the side wall of the support portion 12, and the screw passes through the screw hole from top to bottom and is then locked to the screw column. The pressing portion 72 can abut against the outer periphery of the isolation member 42 and press down the isolation member 42.

[0128] In one embodiment, the fixing member 70 is integrally configured as an open or closed annular member. As shown in the embodiment shown in the figure, the fixing member 70 can be integrally formed as a closed annular member with the steam passage wall 62. Of course, it can also be configured as a plurality of members and these plurality of members are arranged at intervals.
