Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and in particular relates to a cooking utensil. Background Art

[0002] The heating methods of cooking utensils (such as rice cookers and electric pressure cookers) include heating plate heating and electromagnetic heating. The heating device of electromagnetic heating is an electromagnetic wire coil. The electromagnetic wire coil is usually set below the inner pot, and a coil is wound on the electromagnetic wire coil. When powered on, a magnetic field is generated, and the inner pot is located in the magnetic field, so that the inner pot can be heated.

[0003] However, in the prior art, the coil on the electromagnetic wire reel often only covers the bottom area of ​​the inner pot. During the heating process, the heat is concentrated on the bottom of the inner pot, while the heat on the side of the inner pot is lower, resulting in a relatively uneven distribution of heat on the inner pot. For the food inside the inner pot, the upper and lower layers of food are heated unevenly, and the heat is concentrated on the lower layer of food, which will cause the lower layer of food to dry and gelatinize, while the upper layer of food is relatively moist or undercooked.

[0004] Therefore, some cooking utensils increase the height of the electromagnetic wire reel by adding an annular wall above the reel body. At the same time, a coil is also wound on the annular wall so that the bottom and sides of the inner pot are radiated by the coil, thereby being able to heat the bottom and sides of the inner pot at the same time, thereby improving heating efficiency and heating uniformity.

[0005] However, in the prior art, the annular wall and the disk body of the electromagnetic wire disk are often two independent parts, and the two need to be fixed during assembly, which increases the assembly process of the cooking utensil and makes the assembly process of the cooking utensil more complicated. In addition, when winding the coil, it is necessary to wind the wire on the disk body and the annular wall respectively, and the coils in each area are usually in series. Therefore, it is necessary to respectively set connection structures such as wiring terminals at the ends of the coils on the annular wall and the coils on the disk body. After the annular wall and the disk body are assembled, the coils wound on the two are connected in series using the wiring terminals. This not only increases the difficulty and complexity of winding, but also increases the manufacturing cost due to the setting of the wiring terminals. Moreover, when connected through the wiring terminals, when the cooking utensil is used for a long time or when the cooking utensil is shaken or collided, it is easy for the wiring terminals to loosen, which reduces the connection stability of the coils on the disk body and the annular wall.

[0020] 1. In the utility model, the disc body of the electromagnetic wire disc includes an integrally formed arc-shaped portion and a vertical wall. Therefore, during the assembly of the cooking utensil, the disc body can be assembled with the pot body as a complete component, thereby eliminating the assembly steps of the arc-shaped portion and the vertical wall, simplifying the assembly of the whole machine, and improving production efficiency. In addition, since the arc-shaped portion and the vertical wall are integrally formed, the coil can be wound on the arc-shaped portion and the vertical wall by one winding without the need to wind separately. Therefore, the winding difficulty is reduced and the winding efficiency is improved. Moreover, the coils in the first winding area and the second winding area are wound with a continuous wire, and there is no need to connect them through connecting structures such as terminal blocks.

In addition, the limiting structure is provided with a wire groove for the coils to pass through, so as to realize the extension of part of the coils between the first winding area and the second winding area. During the winding process, after the winding in the first winding area or the second winding area is completed, the end of the coil can be directly pulled from the wire groove to the other winding area, so as to continue winding. At the same time, the wire groove can limit the coil, making the transition and extension part of the coil between the first winding area and the second winding area more regular, avoiding large-scale swinging or shaking of this part of the coil during the winding process, making the coil more fit during the winding process and reducing the difficulty of winding.

[0045] like Figure 1 , Figure 2 As shown, a cooking utensil comprises a heat preservation cover 2 and an electromagnetic wire reel 1 located below the heat preservation cover 2, the electromagnetic wire reel 1 comprises a reel body 11 and a coil, the reel body 11 has an arcuate portion 111 and a vertical wall 112 located above the arcuate portion 111 and integrally formed with the arcuate portion 111, the arcuate portion 111 is provided with a first winding area 1111, the vertical wall 112 is provided with a second winding area 1121, the coil is wound around the first winding area 1111 and the second winding area 1121, and extends from the first winding area 1111 to the second winding area 1121.

[0046] Specifically, Figure 2 As shown, the arc portion 111 includes the bottom wall of the disk body 11 and the side wall extending upward in an arc shape, and the vertical wall 112 extends upward from the side wall. The vertical wall 112 can extend vertically upward or extend upward at an angle with the vertical plane, which is not limited here.

[0047] In the utility model, the disc body 11 of the electromagnetic wire disc 1 includes an arc-shaped portion 111 and a vertical wall 112 that are integrally formed. Therefore, during the assembly of the cooking utensil, the disc body 11 can be assembled with the pot body as a complete component, thereby eliminating the assembly steps of the arc-shaped portion 111 and the vertical wall 112, simplifying the assembly of the whole machine, and improving production efficiency. In addition, since the arc-shaped portion 111 and the vertical wall 112 are integrally formed, the coil can be wound on the arc-shaped portion 111 and the vertical wall 112 by one winding, without the need to wind separately. Therefore, the winding difficulty is reduced and the winding efficiency is improved. Moreover, the coils of the first winding area 1111 and the second winding area 1121 are wound by a continuous wire, and there is no need to connect them through a connecting structure such as a terminal block, thereby greatly improving the connection stability of the coils in the first winding area 1111 and the second winding area 1121, reducing costs while ensuring work reliability.

[0048] For pressure cooking appliances, during pressure cooking, the inner pot 3 will generate a downward force under the action of the internal air pressure, and the heat preservation cover 2 needs to support the inner pot 3 to withstand the downward pressure of the inner pot 3. However, some inner pots 3 are supported by the contact with the heat preservation cover 2 through the waist (the middle and lower part of the inner pot 3), that is, there is a concave or convex structure in the middle and lower part of the inner pot 3, which reduces the heat transfer efficiency of the inner pot 3 at the pressure-bearing structure. As a result, the heat at the bottom of the inner pot 3 cannot be well transferred upward along the side wall of the inner pot 3, resulting in a large temperature difference between the upper and lower parts of the inner pot 3, affecting the uniformity of heating of the food.

[0049] The utility model extends the vertical wall 112 to the middle of the inner pot 3, and then surrounds the outer periphery of the middle of the inner pot 3, and winds the coil on the vertical wall 112, so that during the cooking process, the coil of the second winding area 1121 can heat the side of the inner pot 3 synchronously, so that the side of the inner pot 3 can be directly heated under the action of the magnetic field. In this way, the heating uniformity of the bottom and middle of the inner pot 3 is improved, and the taste of the cooked food is improved.

[0050] It is understandable that when winding the coil, the coil is first wound to the first winding area 1111 or the second winding area 1121. After the winding of the current area is completed, the coil is pulled to reach another winding area, and then the winding is continued. In this way, the coil does not need to be divided into multiple sections for winding separately, and a continuous wire can be used to complete the winding of all areas on the coil.

[0051] As a preferred embodiment of the utility model, a limiting structure 113 is arranged between the first winding area 1111 and the second winding area 1121. The limiting structure 113 is used to limit the coils wound in the first winding area 1111 and the second winding area 1121. The limiting structure 113 is provided with a wire groove 1131 for the coil to extend from the first winding area 1111 to the second winding area 1121.

[0052] The limiting structure 113 can form a stop limit for the coils in the first winding area 1111 and the second winding area 1121, confining the coils in their respective winding areas, preventing the coils from becoming loose and causing the coils in the two winding areas to be mixed, improving the regularity of the winding, and ensuring the heating effect of the coils in each winding area. In addition, the limiting structure 113 is provided with a wire groove 1131 for the coils to pass through, so that part of the coils can be extended between the first winding area 1111 and the second winding area 1121. During the winding process, after the winding in the first winding area 1111 or the second winding area 1121 is completed, the end of the coil can be directly pulled from the wire groove 1131 to the other winding area to continue winding. At the same time, the wire groove 1131 can limit the coil, making the transition and extension part of the coil between the first winding area 1111 and the second winding area 1121 more regular, avoiding large-scale swinging or shaking of this part of the coil during the winding process, making the coil more docile during the winding process and reducing the difficulty of winding.

[0053] In a specific embodiment, the limiting structure 113 is an annular convex rib disposed between the first winding area 1111 and the second winding area 1121, and the annular convex rib is provided with a wire groove 1131 for the coil to pass through. In other embodiments, the limiting structure 113 may also be other structures, or a separate structure from the disk body 11, and subsequently assembled between the first winding area 1111 and the second winding area 1121 of the disk body 11. For example, the limiting structure 113 is a clamp that is clamped to the disk body 11.

[0054] In a preferred embodiment, Figure 3 As shown, the arc-shaped portion 111 has a bottom wall and a side wall, and the first winding area 1111 includes a bottom winding area 1112 located on the bottom wall and a side winding area 1113 located on the side wall.

[0055] It should be noted that the side wall extends upward in an arc shape so that the arc portion 111 is bowl-shaped as a whole. However, the utility model does not limit the shape of the bottom wall, which can be a curved surface structure or a flat structure, that is, the arc portion 111 is a flat bottom structure so that the coil can be wound to the bottom winding area 1112 of the bottom wall.

[0056] Preferably, there is a gap between the bottom winding area 1112 and the side winding area 1113, but the two areas are also continuously and uninterruptedly wound with a wire to form coils in the two areas. During the cooking process, the bottom coil and the side coil heat the bottom of the inner pot 3 together, forming two heating rings at the bottom of the inner pot 3, forming three-dimensional heating of the bottom of the inner pot 3, and improving the heating effect. At the same time, the inductance can be distributed according to the length of the coil in each winding area to adjust the better heating effect.

[0057] In another preferred embodiment, Figures 1 to 3As shown, the vertical wall 112 is provided with at least one isolation rib 1122 at intervals along the height direction. The isolation rib 1122 separates the second winding area 1121 into at least two winding grooves 1123 , and the coil is wound in the winding groove 1123 .

[0058] The isolation ribs 1122 separate the second winding area 1121 into a plurality of winding grooves 1123, and the coils are respectively wound into the winding grooves 1123. Due to the separation of the isolation ribs 1122, there is a gap between the coils in two adjacent winding grooves 1123, so that during the heating process, multiple heating rings can be formed on the side of the inner pot 3, forming three-dimensional heating of the side of the inner pot 3, thereby improving the heating effect. At the same time, the inductance can be distributed according to the length of the coils in each winding groove 1123 to adjust a better heating effect.

[0059] Specifically, Figure 2 As shown, the second winding area 1121 forms three winding grooves 1123, thereby forming three heating rings on the side of the inner pot 3. Of course, the winding grooves 1123 can also be other numbers, which are not limited here. The isolation ribs 1122 can be as follows Figure 2 The vertical wall 112 is shown as a full circle, but it can also be Figure 1 What is shown are discontinuous segments and are not limited here.

[0060] It should be noted that, although the isolation ribs 1122 divide the second winding area 1121 into a plurality of winding grooves 1123, this embodiment does not limit the number of coils wound in each winding groove 1123. For example, one coil or multiple coils may be wound in each winding groove 1123. The multiple coils in the same winding groove 1123 may be a sparsely wound structure or a densely wound structure, which is not limited here.

[0061] In addition, it should be noted that the above two embodiments can be implemented separately or in combination. For example, the arc portion 111 is provided with a bottom winding area 1112 and a side winding area 1113, and the vertical wall 112 is provided with three winding grooves 1123, which cooperate to form five heating rings on the surface of the inner pot 3 during the heating process, and the heating area radiates from the bottom of the inner pot 3 to the middle of the inner pot 3, so that the food inside the inner pot 3 can be covered more by the heating area of ​​the coil, so that the food is fully heated, and the heating efficiency is improved while ensuring the uniformity of food heating.

[0062] Preferably, if Figure 2 As shown, the upper edge of the vertical wall 112 is provided with a flange 1124 so as to cooperate with the edge 21 of the inner container 3 and to limit the coil in the uppermost winding groove 1123.

[0063] As a preferred embodiment of the present invention, Figure 5As shown, the electromagnetic wire reel 1 also includes a magnetic strip frame 12 and a magnet 4. The reel body 11 is provided with a plug-in protrusion 116. The magnetic strip frame 12 is provided with a plurality of mounting arms 121 along the circumferential direction. The mounting arms 121 are provided with mounting grooves 122 for mounting the magnet 4. The plug-in protrusion 116 can be plugged and matched with the mounting groove 122 so that the plug-in protrusion 116 limits the magnet 4.

[0064] When assembling the disk body 11 and the magnetic strip frame 12, the insertion protrusion 116 and the installation groove 122 can be used for positioning, so that the installation arm 121 of the magnetic strip frame 12 corresponds to the preset position of the disk body 11, and after the two are plugged in, the relative rotation of the disk body 11 and the magnetic strip frame 12 can be limited, thereby facilitating subsequent fixation, reducing the difficulty of assembly, and improving the accuracy of the assembly position. At the same time, after the insertion protrusion 116 is inserted into the installation groove 122, the notch at one end of the installation groove 122 can be closed, thereby limiting the magnet 4 in the installation groove 122, firmly limiting the magnet 4 in the installation groove 122, preventing the magnet 4 from escaping from the installation groove 122, and improving the installation stability of the magnet 4.

[0065] During assembly, the coils are first wound around the winding areas on the disk body 11, and then the plug-in protrusions 116 are plugged into the mounting grooves 122 to form a positioning, and then the magnetic strip frame 12 is fastened to the disk body 11 to form a whole. After the installation is completed, the magnetic strip frame 12 presses part of the coils in the first winding area 1111, so that the coils in the first winding area 1111 fit more closely on the surface of the arc portion 111. Figure 8 As shown, the cooking utensil also includes a water collecting ring 52 located above the heat preservation cover 2 and a base 53 located below the electromagnetic wire reel 1. The base 53 and the water collecting ring 52 are respectively provided with fixing columns 54. The electromagnetic wire reel 1 has a laterally protruding fixing lug 114. The fixing lug 114 is located between the fixing column 54 of the base 53 and the fixing column 54 of the water collecting ring 52. Then, the upper and lower fixing columns 54 are locked by fasteners such as screws, so that the water collecting ring 52 and the base 53 clamp the electromagnetic wire reel 1, making the electromagnetic wire reel 1 more stable.

[0066] As a preferred embodiment of the present utility model, the cooking utensil also includes an inner pot 3 located on the inner side of the heat preservation cover 2, the mouth of the heat preservation cover 2 is provided with a rim 21 and a pressure-bearing section 22 located below the rim 21, the inner pot 3 has a mouth area, the mouth area includes an outer flange 31 and a mating section 32, the mating section 32 is placed on the pressure-bearing section 22, the side wall of the inner pot 3 has an arc section 34 extending from the pressure-bearing section 22 to the bottom of the inner pot 3, and the second winding area 1121 corresponds to the arc section 34.

[0067] For pressure cooking, the matching section 32 of the inner pot 3 abuts and cooperates with the pressure-bearing section 22 of the heat preservation cover 2 to achieve pressure bearing, so that the pressure-bearing position of the inner pot 3 is transferred to the neck of the inner pot 3, which is at a relatively high position, and the middle and lower parts of the inner pot 3 can be designed as a complete and continuous arc surface or straight surface. This improves the integrity and continuity of the middle and lower parts of the inner pot 3 and improves the appearance while ensuring the heat transfer efficiency, so that the heat can be quickly transferred to the bottom and middle of the inner pot 3, thereby improving the uniformity of heating of the upper and lower layers of food and ensuring the cooking taste.

[0068] The complete and continuous arc surface also releases the space on the side of the inner pot 3, avoiding the vertical wall 112, so that the vertical wall 112 can be located in the middle of the inner pot 3. The heating area covers the middle of the inner pot 3, the heating wrapping area is greatly released, and the vertical wall 112 is prevented from interfering with the side wall of the inner pot 3.

[0069] Preferably, if Figure 4 As shown, the arc segment 34 has a height center line 33 , and the projection of the second winding area 1121 toward the inner container 3 covers the height center line 33 .

[0070] The food is concentrated in the space surrounded by the arc segment 34, and the second winding area 1121 covers the height center line 33 of the arc segment 34, so that when the inner pot 3 is filled with a large amount of food, the coil wound by the second winding area 1121 can also heat the middle or upper layer of food, thereby heating it together with the lower layer of food, forming a three-dimensional surround heating from top to bottom, thereby improving the heating uniformity and heating efficiency of the food.

[0071] Preferably, the arc segment 34 has the largest diameter above the height midline 33 and gradually decreases in diameter downward. The second winding area 1121 is set corresponding to the height midline 33, which can heat the position of the arc segment 34 with a larger diameter, thereby forming a heating ring with a larger diameter, which increases the contact area with the food and improves the heating effect on the food.

[0072] The present invention does not limit the winding method of the coil in the first winding area 1111 and / or the second winding area 1121. In a preferred embodiment, Figure 3 As shown, the first winding area 1111 and / or the second winding area 1121 are provided with a wire pressing rib 115, a winding space is formed between the disk body 11 and the wire pressing rib 115, the coil is wound in the winding space, and two adjacent coils are abutted against each other.

[0073] The coil is wound multiple times in the first winding area 1111 and the second winding area 1121, and each coil is in contact with each other to form a dense winding structure, thereby forming a magnetic field with a stronger magnetic field strength during heating, thereby improving the heating effect on the inner pot 3. However, the dense winding structure makes the coil unstable and prone to loosening, so a wire crimping rib 115 is provided to crimp the coil so that the coil fits firmly on the surface of the disk body 11. It should be noted that the first winding area 1111 and the second winding area 1121 can both be densely wound, or one of them can be densely wound and the other can be sparsely wound, so that the bottom and side of the inner pot 3 form a heating method that combines sparse winding heating and dense winding heating, thereby improving the three-dimensionality of the heating.

[0074] As a preferred embodiment of the present invention, Figure 4 , Figure 7 As shown, the second winding area 1121 is located on the outer surface of the vertical wall 112 , and the cooking appliance further includes a shell 5 located outside the heat preservation cover 2 , and a visible window 51 is provided on the side wall of the shell 5 , and the visible window 51 is provided corresponding to the second winding area 1121 .

[0075] In the prior art, some cooking utensils wind the coil on the inner side of the electromagnetic coil 1, that is, on the side facing the inner pot 3, so that when the user takes the inner pot 3 out of the heat preservation cover 2, the coil can be directly observed to achieve visibility of the coil. However, the inner winding method not only makes it easy for the inner pot 3 to rub against the coil, causing damage to the coil and affecting the heating effect, but also the water vapor, oil stains and food residues on the outer surface of the inner pot 3 will directly fall onto the coil, causing contamination of the coil, thereby affecting the distribution of the magnetic field, and reducing the heating effect and heating uniformity of the inner pot 3.

[0076] In this embodiment, the coil is wound on the outside of the pan 11, so that impurities inside the heat preservation cover 2 cannot directly contact the coil, thereby ensuring the cleanliness of the coil and the heating effect. Through the visual window 51 on the side wall of the shell 5, the user can directly observe the coil wound on the outer surface of the vertical wall 112 from the outside of the cooking utensil. The user can more intuitively see the winding position of the internal coil, and then the product heats the bottom and side of the inner pot 3 at the same time, forming a three-dimensional circulation electromagnetic heating method, which is more intuitive, which is conducive to users' understanding of the product and more conducive to product promotion.

[0077] Furthermore, during implementation, a decorative piece may be further provided on the second winding area 1121 or the coil, so that the user can obtain a better visual experience when observing through the visual window 51. For example, a light strip or other light-emitting element may be provided on the coil or the second winding area 1121, and when the coil is powered on, the light-emitting element is synchronously lit, so that the user may have a better visual experience.

[0078] It should be noted that the present invention does not limit the location and visible range of the visible window 51. Figure 7 As shown, the visual window 51 is arranged on the side of the pot body. The visual window 51 can be located on one side of the pot body, or can be symmetrically arranged on both sides of the pot body. In addition, the visual window 51 can also extend horizontally into a long strip shape, so that the user can obtain a wider viewing angle and improve the overall appearance of the machine.

[0079] In another embodiment, the visible window 51 extends along the circumference of the outer shell 5 21 to surround at least a portion of the circumference of the outer shell 5. The visible window 51 extends along the circumference of the outer shell 5 21. On the one hand, it increases the area of ​​the visible window 51 so that the user can get a better viewing experience. On the other hand, it can also beautify and decorate the overall shape of the cooking utensil. For example, when the cooking utensil is working, a circle of luminous decorative ring can be formed on the outer shell 5 by combining with the light-emitting element arranged in the second winding area 1121, which not only improves the visual experience, but also allows the user to directly know the working status of the cooking utensil by whether the light-emitting element is emitting light or not. Among them, the visible window 51 can be a complete circle to completely surround the outer shell 5, or it can be a discontinuous plurality of segments, which are arranged at intervals on the outer shell 5, which is not limited here.
