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.
[0079] The preferred embodiment of the present invention provides a cooking utensil, which comprises a pot body and a cover body 1 (such as Figure 1As 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.
[0080] 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.
[0081] 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.
[0082] 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.
[0083] 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.
[0084] 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.
[0085] 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.
[0086] 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.
[0087] 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.
[0088] 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, which is suitable for respective cooking conditions. In this solution, the heating element 41 may be a heating layer, a heating wire, etc.
[0089] 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.
[0090] 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.
[0091] 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.
[0092] 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.
[0093] 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.
[0094] 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 3 As 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.
[0095] 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.
[0096] In order to better fix the isolation member 42, as Figure 2As 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.
[0097] 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.
[0098] In one example, for example Figures 1 to 5 In the illustrated embodiment shown, the cover body 1 includes a first sealing ring 52. The first sealing ring 52 can be arranged at the opening edge portion 38. The first sealing ring 52 is at least arranged 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. As a result, 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 from 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.
[0099] 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.
[0100] 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.
[0101] 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 assembly 30 of this embodiment further includes a heat-conducting member 80. It can be understood that the heat-conducting member 80 has good heat-conducting properties and can effectively transfer heat. The heat-conducting member 80 is fixed to the removable cover 31 and protrudes relative to the removable cover 31 toward the isolation member 42. Figure 4 As shown, the top surface of the heat conductive member 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 .
[0102] In this embodiment, when the cooking utensil is used for cooking, the heat conducting member 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.
[0103] The heat conducting member 80 can be arranged around the removable cover opening 33, and further, the heat conducting member is fixed to the opening edge portion 38. The heat conducting member 80 corresponds to the low temperature area of the removable cover 31, and the heat conducting member 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 member 80 has better thermal conductivity and better thermal conductivity efficiency.
[0104] The width W of the cross section of the heat conducting member 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 member 80 and the spacer 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.
[0105] The heat conducting member 80 is disposed intermittently or continuously along the removable cover opening 33. In the illustrated embodiment, as shown in FIG. Figure 5As shown, the heat conducting member 80 is continuously disposed along the removable cover opening 33 , and the heat conducting member 80 is configured in an open loop shape or a closed loop shape extending along a predetermined loop line. Figure 5 It is shown that the heat conducting member 80 is in a closed loop shape, and its shape corresponds to the shape of the removable cover opening 33, that is, the predetermined loop line is defined by the shape of the removable cover opening 33. Thus, the heat conducting efficiency is high, heat can be effectively transferred, the structure is simple, and it can be easily manufactured and assembled.
[0106] In other embodiments not shown, the heat conducting member 80 is intermittently arranged along the removable cover opening 33 to form a multi-stage structure. Specifically, the heat conducting member 80 is configured into a plurality of sections arranged at intervals along a predetermined annular line. Each section can be in any suitable shape such as a square or a strip. As a result, the heat conduction efficiency is high, heat can be effectively transferred, the material usage is reduced, and the material cost is reduced.
[0107] like Figures 4 to 7 As shown, the removable cover 31 includes a cover body portion 37 and an opening edge portion 38 forming the opening of the removable cover. The cover body portion 37 is connected to the opening edge portion 38. The heat-conducting member 80 can be fixed to at least one of the cover body portion 37 and the opening edge portion 38. Optionally, the heat-conducting member 80 is fixed to the opening edge portion 38. The heat of the isolation member 42 can be first transferred to the opening edge portion 38 through the heat-conducting member 80, and then transferred to other parts of the removable cover 31; and the opening edge portion 38 is easy to be provided with a structure for fixing the heat-conducting member 80, which is conducive to simplifying the structure of the removable cover 31.
[0108] As described above, a sealing ring is required to be provided between the spacer 42 and the removable cover 31 to form a seal. The sealing ring may be located at least one of the radial inner side and the radial outer side of the heat-conducting member 80. For example, the sealing ring provided at the support portion is located at the radial outer side of the heat-conducting member 80, and the sealing ring provided at the opening edge portion 38 is located at the radial inner side of the heat-conducting member 80.
[0109] In one example, if Figures 1 to 5 As shown, the sealing ring is located radially inside the heat-conducting member 80. That is, this example includes a first sealing ring 52. The heat-conducting member 80 presses down the first sealing ring 52 and the two are fixed to the opening edge portion 38 together. The heat-conducting member 80 is made of a rigid heat-conducting material, so that a part of the first sealing ring 52 can be clamped between the heat-conducting member 80 and the removable cover 31. The heat-conducting member 80 can not only have a heat-conducting function, but also can be used for the installation of the sealing ring, avoiding the additional provision of a component for fixing the sealing ring, simplifying the structure of the removable cover assembly 30, and reducing the production cost.
[0110] In this program, Figure 5The heat conducting member 80 is shown as a closed loop shape; of course, if needed and / or desired, the heat conducting member 80 may also be an open shape, or a plurality of sections disposed at intervals.
[0111] like Figure 4 As shown, the heat-conducting member 80 may include a main body portion 81, a connecting portion 82 and a heat-conducting portion 83 connected to each other. The connecting portion 82 protrudes radially inward relative to the main body portion 81, and the connecting portion 82 is connected to the removable cover 31. The heat-conducting portion 83 can protrude toward the isolation member 42 relative to the main body portion 81. The main body portion 81 can be closely attached to the upper surface of the removable cover 31 to form an upward support. The connecting portion 82 at least partially extends into the groove of the first sealing ring on the circumferential outer side.
[0112] The removable cover 31 may be provided with bendable feet 50 at intervals, and the feet 50 are arranged at intervals along the opening edge portion 38. The heat conducting member 80 is connected to the removable cover 31 by bending the feet 50. For example, Figure 5 As shown, the opening edge 51 of the opening edge portion 38 is bent upward to form a ring, and the first sealing ring 52 is located radially outside the opening edge 51 and abuts against the opening edge 51. The clamping foot 50 extends upward from the top of the opening edge 51, is bent relative to the opening edge 51, and is buckled to the upper surface of the first sealing ring 52.
[0113] Specifically, the first sealing ring 52 includes a base portion 54 and a sealing portion 55. The sealing portion 55 extends upward from the base portion 54 and has a deformable shape, such as any suitable shape such as a roughly V-shaped cross section. The clamping foot 50 is bent and snapped onto the upper surface of the base portion 54. The connecting portion 82 of the heat-conducting member 80 extends into the groove of the base portion 54, and the bent clamping foot 50 clamps the connecting portion 82 and the base portion 54 on the removable cover 31. Optionally, the groove may be annular or arc-shaped. When the groove is arc-shaped, the arc-shaped grooves are spaced apart in the circumferential direction.
[0114] In another example, if Figure 6 and Figure 7 As shown, the heat-conducting member 80 is fixed to the opening edge portion 38 separately. Exemplarily, the heat-conducting member 80 is provided with a slot 101 with an opening facing downward, and the opening edge 51 of the opening edge portion 38 is bent upward and located in the slot 101. The heat-conducting member 80 is provided with a through hole corresponding to the position of the card foot 50, and the through hole is specifically located at the connecting portion 82. The card foot 50 connected to the opening edge 51 extends through the through hole and then bends, and the bent card foot 50 is clamped to the connecting portion 82. The heat-conducting member 80 is made of a flexible heat-conducting material and is in a closed loop shape, which is used to form a seal between the isolation member 42 and the removable cover 31. The flexible heat-conducting material can be, for example, any suitable material such as heat-conducting silicone.
[0115] The heat-conducting component 80 of the present solution not only has the function of heat conduction, but also can seal the gap between the removable cover 31 and the isolation member 42 to prevent steam and liquid from entering the interior of the cover body, avoid the need for an additional sealing ring to form a seal between the isolation member 42 and the removable cover 31, simplify the structure of the removable cover assembly 30, and reduce the production cost.
[0116] In another example not shown, the sealing ring may be located radially outside the heat-conducting member 80, that is, the first sealing ring 52 may not be provided at the opening edge portion 38, but a second sealing ring 53 at the support portion 12 may be provided, and the second sealing ring 53 can form a seal between the spacer 42 and the removable cover 31. Specifically, the second sealing ring 53 has a sealing portion 55 extending downward, and the sealing portion 55 abuts against the removable cover 31. The heat-conducting member 80 is fixed to the opening edge portion 38 separately, and the heat-conducting member 80 is made of a rigid heat-conducting material and is in a closed loop shape. In this solution, the heat-conducting member 80 is preferably in contact with the spacer 42.
[0117] The heat-conducting component 80 of the present solution not only has the function of heat conduction, but also can block some steam and liquid from entering the interior of the cover body. The seal between the removable cover 31 and the isolation member 42 is formed on the radial inner side of the heat-conducting component 80 to prevent steam and liquid from entering the interior of the cover body.
