Description

Technical Field

[0001] This invention relates to the field of kitchen appliance technology, and more particularly to a slow cooker. Background Technology

[0002] A slow cooker is a kitchen appliance used to slowly and evenly heat food, allowing it to retain sufficient moisture during cooking and resulting in a better texture.

[0003] Existing slow cookers do not allow for real-time monitoring of the food's cooking process, requiring the lid to be opened. This results in significant heat loss, preventing the food from reaching its ideal texture within the set time. Furthermore, while existing slow cookers use magnetic stirring devices to rotate and agitate the fluid inside the pot for even heating, the magnetic component is located inside the pot and in contact with the fluid, making it easy for users to accidentally remove it when taking out the food. Summary of the Invention

[0004] To address at least one problem existing in the prior art, the present invention provides a slow cooker.

[0005] A slow cooker includes a main body, an inner pot, a heating element, a stirring element, and a limiting element. The main body includes a pot body and a lid, with the lid covering the pot body. The pot body has an assembly cavity, and the lid includes a transparent structure opposite to the assembly cavity. The inner pot is connected to the pot body and located within the assembly cavity, with a receiving cavity formed inside. The heating element is located between the inner pot and the pot body and provides heat to the inner pot. The stirring element includes a power assembly and a stirring component, which is located within the receiving cavity. The power assembly and the stirring component are spaced apart on opposite sides of the inner pot, and the power assembly drives the stirring component to rotate. The limiting element is connected to the inner pot, and the limiting element and the inner pot enclose a limiting space. The limiting element has a water outlet communicating with the limiting space, and the stirring component is located within the limiting space, which restricts the range of motion of the stirring component.

[0006] In some embodiments, the heating component includes a heating element and an elastic element. The heating element is attached to the outer side of the inner liner, and the two ends of the elastic element are elastically connected to the two ends of the heating element, respectively. The elastic element pulls the two ends of the heating element together in a direction that brings them closer to each other, so that the heating element is in close contact with the outer side of the inner liner.

[0007] In some embodiments, the heating element further includes a fixing plate connected to the inner liner, the fixing plate holding the heating element against the inner liner.

[0008] In some embodiments, the pot lid further includes a lid body, the middle region of which has an installation space, and the transparent structure is disposed within the installation space; the transparent structure includes a transparent portion and a connecting portion connected to each other, the connecting portion is disposed at the edge of the transparent portion, the lid body has a connecting groove, and the connecting portion is inserted into the connecting groove; wherein, the thickness of the connecting portion is greater than the thickness of the transparent portion, and the transparent portion and the lid body are spaced apart.

[0009] In some embodiments, the pot lid further includes a handle, a buffer, and a fixing member. The transparent structure has at least one fixing hole. The buffer passes through the fixing hole and is connected to the transparent structure. The handle is connected to the buffer. The buffer has a through hole inside. The fixing member passes through the through hole and is connected to the handle.

[0010] In some embodiments, the slow cooker further includes a rack that can be selectively placed in the receiving cavity, the rack having multiple slots for placing food.

[0011] In some embodiments, the pot body includes an upper shell, a middle shell, and a lower shell connected sequentially from top to bottom. The upper shell, the middle shell, and the lower shell together enclose the assembly cavity. The open end edge of the inner liner is bent outward to form a bent portion, and the bent portion is connected to the upper shell.

[0012] In some embodiments, the slow cooker further includes circuit components. The pot body includes a lower shell located at its bottom and a cover plate detachably connected to the lower shell. At least a portion of the outer surface of the lower shell protrudes towards the inner pot to form a protrusion. The protrusion has a mounting groove inside. The circuit components are disposed in the mounting groove and spaced apart from the protrusion. The mounting groove is open towards the outside of the pot body. The cover plate covers the open end of the mounting groove.

[0013] In some embodiments, the pot body further includes a reinforcing structure, which is circumferentially disposed on the inner side of the lower shell along the direction from the edge of the lower shell to its center. The reinforcing structure includes an outer layer, a reinforcing rib, and an inner layer, with the reinforcing rib connecting the outer layer and the inner layer respectively.

[0014] In some embodiments, the slow cooker further includes a heat-insulating sheet, the opposite sides of which abut against the inner side of the main body component and the outer side of the inner pot, respectively.

The heating element is located between the inner pot and the pot body and provides heat to the inner pot. The stirring element includes a power component and a stirring piece, which is located within the accommodating cavity. The power component drives the stirring piece to rotate. The limiting element and the inner pot enclose a limiting space, within which the stirring piece is located, limiting the range of motion of the stirring piece. Compared with the prior art, this invention, by providing a transparent structure and a limiting element, allows users to directly observe the cooking state of the food in the accommodating cavity through the transparent structure, determining whether to stir or add seasonings, improving the convenience of use and achieving better cooking results. The limiting space restricts the movement of the stirring piece, limiting its range of motion to within the limiting space. This avoids removing the stirring piece when taking out the food, solving the problem of the stirring piece being difficult to separate from the food. Attached Figure Description

[0042] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0047] The present invention will now be described in further detail with reference to the accompanying drawings.

[0048] See Figure 1A slow cooker includes a pot body 11, a lid 12, and an inner pot 2. The lid 12 covers the pot body 11, and the pot body 11 has an assembly cavity S1. The lid 12 includes a transparent structure 122 opposite to the assembly cavity S1. The inner pot 2 is connected to the pot body 11 and located within the assembly cavity S1. The inner pot 2 has a receiving cavity S2 for holding food. It should be noted that the transparent structure 122 is a transparent component that allows light to pass through without changing the direction of light emission. The transparent structure 122 can be made of inorganic glass or acrylic, exhibiting excellent optical performance.

[0049] It should be noted that the inner liner 2 and the pot body 11 can be connected by various methods such as welding, screws, snap-fitting, or overlapping.

[0050] By setting a transparent structure 122 on the pot lid 12, and the transparent structure 122 being opposite to the assembly cavity S1, the transparent structure 122 is also opposite to the accommodating cavity S2. Therefore, during the cooking process, the user can directly observe the cooking status of the food in the accommodating cavity S2 through the transparent structure 122 to determine whether it is necessary to stir or add seasonings, thereby improving the convenience of using the device and achieving better cooking results.

[0051] See Figure 2 The slow cooker also includes a heating element 3, a stirring element 4, and a limiting element 5. The heating element 3 is located between the inner pot 2 and the pot body 11 and is used to provide heat energy to the inner pot 2. The stirring element 4 includes a power assembly 41 and a stirring element 42. The stirring element 42 is located in the accommodating cavity S2. The power assembly 41 and the stirring element 42 are spaced apart on opposite sides of the inner pot 2. The power assembly 41 is used to drive the stirring element 42 to rotate.

[0052] In practical applications, food is placed in the accommodating cavity S2 of the inner liner 2, and then liquid is added to the accommodating cavity S2. The heating component 3 can be fitted into the inner liner 2. Through the heating function of the heating component 3, the heating component 3 heats the inner liner 2, and the inner liner 2 transfers heat to the liquid inside. The heating liquid continuously heats the food. At the same time, the power component 41 drives the stirring component 42 in the accommodating cavity S2 to rotate, so that it stirs the liquid, thereby driving the liquid to be heated evenly in the inner liner 2, so that the temperature of all parts of the food is the same, avoiding the situation where the bottom of the food is heated higher and the top is heated lower.

[0053] In one embodiment, the stirring component 4 employs magnetic stirring; specifically, see [reference needed]. Figure 4The stirring element 42 is a magnet. The power assembly 41 may include a driving element 411 and a magnetic element 412. The driving element 411 may be a motor, and the magnetic element 412 may also be a magnet. The motor (driving element 411) is connected to the magnetic element 412 and drives the magnetic element 412 to rotate. The movement of the magnetic element 412 generates a magnetic field, and the stirring element 42 (magnet) rotates under the action of the magnetic field to achieve the stirring function. In other embodiments, the driving element 411 may also be an electric motor, and the magnetic element 412 may be an iron rod with a wire, an electromagnetic relay, etc.

[0054] See Figure 3 and Figure 4 The aforementioned limiting component 5 is connected to the inner liner 2, and the limiting component 5 and the inner liner 2 enclose a limiting space 51. The limiting component 5 has a water outlet 52 that communicates with the limiting space 51. The stirring component 42 is located in the limiting space 51, and the limiting space 51 is used to limit the movement range of the stirring component 42.

[0055] To address the problem of difficulty in separating the mixing element 42 from the food, this application includes a limiting component 5. The limiting component 5 and the inner liner 2 enclose a limiting space 51, which restricts the movement of the mixing element 42 within the limiting space 51. This prevents the mixing element 42 from being removed when the food is taken out. A water outlet 52 is provided on the limiting component 5 to allow the mixing element 42 to mix with the liquid inside the inner liner 2, facilitating agitation by the mixing element 42.

[0056] In one embodiment, the limiting component 5 can be a cover structure, covering the stirring component 42. The limiting component 5 can be detachably connected to the inner pot 2. After cooking is completed, the limiting component 5 can be removed and the stirring component 42 can be taken out for cleaning to prevent the stirring component 42 from being contaminated with food residue and affecting the next cooking.

[0057] Compared to existing technologies, this application, by setting a transparent structure 122 and a limiting component 5, allows users to directly observe the cooking state of the food in the accommodating cavity S2 through the transparent structure 122, so as to determine whether it is necessary to stir or add seasonings, thereby improving the convenience of using the device and achieving better cooking results; the limiting space 51 restricts the stirring component 42, and the movement range of the stirring component 42 is limited to the limiting space 51, so that when the food is taken out, the stirring component 42 can be avoided, solving the problem that the stirring component 42 is difficult to separate from the food.

[0058] See Figure 5 The heating component 3 includes a heating element 31 and an elastic element 32. The heating element 31 is attached to the outer side of the inner liner 2. The two ends of the elastic element 32 are elastically connected to the two ends of the heating element 31 respectively. The elastic element 32 pulls the two ends of the heating element 31 together in a direction that brings them closer to each other, so that the heating element 31 is attached to the outer side of the inner liner 2.

[0059] In one embodiment, the heating element 31 is elongated and preferably surrounds the outer surface of the inner liner 2. It can be tightly fitted to the inner liner 2 by pressing or abutting, so that the heating element 31 can transfer heat to the inner liner 2 with maximum efficiency. The two ends of the elastic element 32 are connected to the two ends of the heating element 31, pulling the two ends of the heating element 31 closer together. The elastic element 32 continuously applies tension to the two ends of the heating element 31, ensuring that it remains tightly fitted to the outer surface of the inner liner 2. The elastic element 32 can be a spring or similar component.

[0060] By circling the heating element 31 on the outer side of the inner liner 2, the heating element 31 can heat the inner liner 2 simultaneously from all four sides, greatly improving the uniformity and stability of heating. The elastic element 32 is elastically connected to both ends of the heating element 31, ensuring that the heating element 31 always fits snugly against the inner liner 2. Specifically, the heating element 31 is typically made of metal. Metal expands and contracts with temperature changes, causing the heating element 31 to elongate as the temperature rises. If the two ends of the heating element 31 are fixed, the middle part of the heating element 31 will bend due to thermal expansion and contraction, creating a gap between the heating element 31 and the inner liner 2, affecting the efficiency of heat transfer. Through the elastic action of the elastic element 32, when the heating element 31 elongates during heating, the elastic element 32 contracts to pull the two ends of the heating element 31 closer together. This ensures that the heating element 31 remains tightly fitted to the outer side of the inner liner 2 during heating, thus achieving uniform heating.

[0061] See Figure 6 In one embodiment, the elastic element 32 and the heating element 31 are connected in the following way: the heating element 31 has hook holes 311 at both ends, and the elastic element 32 has hook claws 321 at both ends. The hook claws 321 hook the hook holes 311, so that the elastic element 32 is connected to both ends of the heating element 31 respectively. With this arrangement, the installation and replacement of the elastic element 32 are more convenient.

[0062] See again Figure 5 In one embodiment, the heating element 3 further includes a fixing piece 33 connected to the inner liner 2. The fixing piece 33 holds the heating element 31 against the inner liner 2, enhancing the stability of the fit between the heating element 31 and the inner liner 2, and further preventing gaps or detachment between the heating element 31 and the inner liner 2. The fixing piece 33 can be fixed to the inner liner 2 by welding, snap-fitting, screwing, or other methods. Multiple fixing pieces 33 can be provided, spaced circumferentially on the inner liner 2, to hold the heating element 31 against it from multiple angles.

[0063] Specifically, the fixing piece 33 includes a fixing part 331 and a supporting part 332. The fixing part 331 is fixed to the bottom surface of the inner liner 2, and the supporting part 332 is connected to the fixing part 331 and extends outward along the inner liner 2. The supporting part 332 elastically supports the heating element 31. In practical applications, the supporting part 332 is the part of the fixing piece 33 used to contact and support the heating element 31, and the fixing part 331 is the part of the fixing piece 33 used to fix it to the inner liner 2. The supporting part 332 has an elastic force towards the heating element 31 to press the heating element 31. The supporting part 332 can be wavy to enhance the elastic force of the supporting part 332. At the same time, it can also make the contact surface between the supporting part 332 and the heating element 31 a smooth arc surface to prevent damage to the exterior of the heating element 31 during pressing and supporting. The wavy structure can also play a guiding role in the assembly process of the inner liner 2, making assembly convenient.

[0064] In one embodiment, see Figure 6 The heating element 31 includes a heating element 312 and a protective frame 313. The protective frame 313 surrounds and is connected to the inner liner 2. The heating element 312 is disposed on the side of the protective frame 313 near the inner liner 2. The two ends of the elastic element 32 are respectively connected to the two ends of the heating element 312. The outermost frame structure of the protective frame 313 is used to protect the heating element 312 inside. The heating element 312 is a metal sheet used to convert electrical energy into heat energy. The heating element 312 is movably disposed inside the protective frame 313. The elastic element 32 connects the two ends of the heating element 312 so that the heating element can always maintain a taut and close fit. Since the heating element 312 softens when heated, it is easily damaged. The protective frame 313 can protect and limit the heating element 312.

[0065] Specifically, the edge of the protective frame 313 curls towards the side where the heating element 312 is located to form a curled structure 314, which wraps around the edge of the heating element 312. Since the heating element 312 is often relatively thin, its edge is easily damaged. The curled structure 314 can wrap around the edge of the heating element 312 to protect it. Furthermore, the curled structure 314 can form a groove-like structure for the heating element 312, which can restrict the position of the heating element 312 inside the protective frame 313 and prevent the heating element 312 from coming out.

[0066] See Figure 7The pot lid 12 also includes a lid body 121. The middle area of ​​the lid body 121 has an installation space 1214, and the transparent structure 122 is disposed in the installation space 1214. The transparent structure 122 includes a transparent part 1221 and a connecting part 1222 connected to each other. The connecting part 1222 is disposed at the edge of the transparent part 1221. The lid body 121 has a connecting groove 1211, and the connecting part 1222 is inserted into the connecting groove 1211. The thickness of the connecting part 1222 is greater than the thickness of the transparent part 1221, and the transparent part 1221 and the lid body 121 are spaced apart.

[0067] In one embodiment, the cover 121 includes a first outer shell 1212 and a second outer shell 1213 disposed vertically. The first outer shell 1212 and the second outer shell 1213 are detachably connected together. After the first outer shell 1212 and the second outer shell 1213 are connected together, a connecting groove 1211 is formed at their edges. The hollow area between the first outer shell 1212 and the second outer shell 1213 is the installation space 1214. The connecting groove 1211 is arranged around the installation space 1214 and communicates with the installation space 1214. The installation space 1214 is used to install a light-transmitting structure. Specifically, refer to... Figure 10 The light-transmitting structure includes a connecting part 1222 and a viewing part 1221. The connecting part 1222 is arranged around the viewing part 1221. The connecting part 1222 is inserted or locked in the connecting groove 1211. At the same time, the viewing part 1221 is located in the installation space 1214. The first outer shell 1212 and the second outer shell 1213 are respectively clamped from the top and bottom of the connecting part 1222 from opposite sides. Since the thickness of the connecting part 1222 is greater than the thickness of the viewing part 1221, the viewing part 1221 is separated from the first outer shell 1212 and the second outer shell 1213. This can effectively prevent the vibration or thermal deformation generated by the first outer shell 1212 and the second outer shell 1213 from being transmitted to the viewing part 1221, thus preventing the viewing part 1221 from breaking.

[0068] The transparent part 1221 is a transparent component that allows light to pass through without changing the direction of light emission. The transparent part 1221 can be made of inorganic glass or acrylic structure, and has excellent optical performance. The first outer shell 1212 and the second outer shell 1213 can be made of plastic or aluminum alloy, which are inexpensive materials with excellent mechanical properties and light weight.

[0069] It is understandable that the lid also includes a sealing element 1215, which is connected to the second outer shell 1213. When the lid 12 is placed on the pot body 11, the sealing element 1215 plays a sealing role, sealing the gap at the connection between the lid 12 and the pot body 11 to prevent heat loss.

[0070] See Figure 8 and Figure 9The pot lid 12 also includes a handle 123, a buffer 124, and a fixing member 125. The transparent structure 122 has at least one fixing hole 1223. The buffer 124 passes through the fixing hole 1223 and is connected to the transparent structure 122. The handle 123 is connected to the buffer 124. The buffer 124 has a through hole inside. The fixing member 125 passes through the through hole and is connected to the handle 123.

[0071] To facilitate user handling of the pot lid 12, this application includes a handle 123. The viewing section 1221 has at least one fixing hole 1223. A buffer 124 passes through the fixing hole 1223, with its two ends abutting against the two sides of the viewing section 1221. A fixing member 125 passes through the buffer 124 and connects to the handle 123, thus fixing the handle 123 and the viewing section 1221 together. By providing the buffer 124, the handle 123 and the viewing section 1221 are connected without contact, effectively reducing the impact of external force on the viewing section 1221. When the user holds the handle 123, vibrations on the handle 123 mainly affect the fixing member 125 and the buffer 124, with minimal impact on the viewing section 1221, ensuring the shape consistency of the viewing section 1221 and guaranteeing the realism of the displayed image. The buffer 124 can be an I-nut, an embedded nut, etc., and the fixing member 125 can be a bolt, screw, etc.

[0072] See Figure 11 The slow cooker also includes a rack 6, which can be selectively placed in the accommodating cavity S2. The rack 6 has multiple storage slots 61 for placing food. In practical applications, users can choose to use the rack 6 as needed. For example, when heating meat, seasoning packets, or other foods, the rack 6 can be placed in the accommodating cavity S2 to secure the food and prevent it from shaking in the inner pot 2, which could easily damage the outer packaging.

[0073] In one embodiment, the placement rack 6 includes a first frame 62, a second frame 63 and a third frame 64. The first frame 62 forms a loop-shaped frame structure, and a plurality of second frames 63 are arranged at intervals along the width direction of the loop-shaped frame structure. The second frames 63 are wave-shaped, and the third frame 64 is connected to the trough of the second frames 63.

[0074] The first frame 62, serving as the supporting framework for the shelf 6, is located on the outermost perimeter. Multiple second frames 63 are spaced apart within the area enclosed by the first frame 62. Storage slots 61 can be formed between the first and second frames 62, and between adjacent second frames 63. Meat, seasoning packets, and other food items are inserted into these slots 61, allowing for quick removal after heating. The third frame 64 enhances the connection stability between the first and second frames 62 and 63, thereby strengthening the overall structural integrity of the shelf 6 and making it more stable within the inner liner 2.

[0075] It is understood that in other embodiments, the shelf 6 may also be set in other ways, such as a mesh structure, with each mesh forming a storage slot 61. This application does not limit this.

[0076] See Figure 12 The pot body 11 includes an upper shell 111, a middle shell 112 and a lower shell 113 connected from top to bottom. The upper shell 111, the middle shell 112 and the lower shell 113 together form an assembly cavity S1. The three-layer structure of the upper shell 111, the middle shell 112 and the lower shell 113 can facilitate the assembly of the main body 1 and other components during the production process.

[0077] See Figure 13 The open edge of the inner liner 2 is bent outward to form a bent portion 21, which is connected to the upper shell 111. Specifically, a stepped portion 1111 is formed on the top of the upper shell 111, and the open edge of the inner liner 2 matches the stepped portion 1111 so that the open end of the inner liner 2 overlaps the stepped portion 1111. The stepped portion 1111 can play a limiting and guiding role during the assembly of the inner liner 2. The stepped portion 1111 is a step-like part at the edge of the upper shell 111.

[0078] To further enhance the connection between the inner liner 2 and the upper shell 111, in one embodiment, the top of the upper shell 111 is provided with an annular groove 1112 along its circumference, and the open edge of the inner liner 2 is inserted into the groove 1112. This arrangement serves to fix the inner liner 2 on the one hand, and to make the inner liner 2 and the pot body 11 sealed together on the other hand, reducing heat loss and improving heating efficiency.

[0079] See Figure 14 The slow cooker also includes an electrical component 7. The pot body 11 includes a lower shell 113 located at its bottom and a cover plate 114 detachably connected to the lower shell 113. At least a portion of the outer surface of the lower shell 113 protrudes towards the inner pot 2 to form a protrusion 1131. A mounting groove 1132 is provided inside the protrusion 1131. The electrical component 7 is disposed in the mounting groove 1132 and spaced apart from the protrusion 1131. The mounting groove 1132 is open towards the outside of the pot body 11, and the cover plate 114 covers the open end of the mounting groove 1132.

[0080] In practical applications, the protrusion 1131 extends along the direction close to the inner pot 2, saving design space and making the bottom surface of the lower shell 113 flat, which is convenient for placement. The protrusion 1131 has an installation groove 1132 inside, which is open to the outside of the pot body 11. Specifically, it can be open to the direction away from the inner pot 2, that is, open to the bottom surface of the lower shell 113. The cover plate 114 covers the open end of the installation groove 1132 and is detachably connected to the lower shell 113. This arrangement allows the circuit board to be exposed when the circuit component 7 is repaired by removing the cover plate 114, which is convenient for inspection.

[0081] It is understandable that the cover plate 114 and the lower housing 113 can be detachably connected by bolts, screws or other means; the mounting groove 1132 can also be an open side facing the lower housing 113, so that the slow cooker does not need to be turned over during maintenance.

[0082] See Figure 15 In one embodiment, since there are many contacts on the back of the circuit component 7, and in order to avoid the circuit component 7 being affected by the temperature of the inner liner 2, the circuit component 7 and the protrusion 1131 are spaced apart; the bottom plate of the protrusion 1131 is provided with a plurality of fixing seats 1134 on the side facing the circuit component 7, and the circuit component 7 is attached to the fixing seats 1134. The fixing seats 1134 separate the circuit component 7 from the protrusion 1131, which can effectively reduce and hinder the transfer of heat to the circuit component 7.

[0083] More specifically, at least a portion of the base plate of the protrusion 1131 protrudes in the direction close to the circuit component 7 to form a boss 1133. The boss 1133 can also hold the circuit component 7 in place when the circuit component 7 is slightly bent, preventing the circuit component 7 from bending excessively, which could lead to malfunction or even breakage. When installing the circuit component 7, the boss 1133 can also hold the circuit component 7 at a certain height, making it easier to determine the fixed position of the circuit component 7 and to facilitate the installation and positioning of the circuit component 7.

[0084] See Figure 16 The pot body 11 also includes a reinforcing structure 115, which is arranged around the inner side of the lower shell 113. Along the edge of the lower shell 113 to its center, the reinforcing structure 115 includes an outer layer 1151, a reinforcing rib 1152 and an inner layer 1153, with the reinforcing rib 1152 connecting the outer layer 1151 and the inner layer 1153 respectively.

[0085] When a slow cooker is moved or accidentally dropped, the lower shell 113 is usually the first part to be impacted. The reinforced structure 115 increases the structural strength of the outer side of the lower shell 113, greatly improving its impact resistance. (See also...) Figure 17The reinforcing structure 115 consists of an outer layer 1151, a reinforcing rib 1152, and an inner layer 1153. The reinforcing rib 1152 is located between the inner layer 1153 and the outer layer 1151. The reinforcing rib 1152 is a sheet-like structure and is set perpendicular to the inner layer 1153 and the outer layer 1151. If the bottom of the slow cooker is subjected to a severe impact (such as falling), the reinforcing rib 1152 can absorb the impact by deforming, minimizing the impact on other parts of the slow cooker. At the same time, there is a gap between the inner layer 1153 and the outer layer 1151, and the reinforcing rib 1152 can be evenly spaced in the circumference within this gap. While ensuring the structural strength, it also helps to improve the heat preservation performance of the slow cooker.

[0086] In one embodiment, see Figure 18 The lower housing 113 is also provided with a wire clamping part 116, which consists of two mirror-distributed claws. The free ends of the claws are close to each other and have bevels on the side. The power cord 9 passes through the free ends of the two claws and is clamped between the two claws to fix the function of the power cord 9 and prevent the drive unit 411 from getting tangled in the power cord 9 when rotating.

[0087] See again Figure 14 The slow cooker also includes a heat-insulating sheet 8, with its opposite sides abutting against the inner side of the main body component 1 and the outer side of the inner pot 2, respectively. The heat-insulating sheet 8 surrounds the heating element 3 and the outer side of the inner pot 2, serving to insulate against heat. This improves the heating efficiency of the heating element 3 and keeps the inner pot 2 warm, slowing down heat loss. It also prevents heat transfer to the pot body 11, avoiding damage due to overheating and preventing burns to the user. The heat-insulating sheet 8 is made of heat-insulating materials such as inorganic cotton.

[0088] A slow cooker includes a pot body 11, a lid 12, an inner pot 2, a heating element 3, a stirring element 4, and a limiting element 5. The lid 12 covers the pot body 11, and an assembly cavity S1 is formed inside the pot body 11. The lid 12 includes a transparent structure 122 disposed opposite to the assembly cavity S1. The heating element 3 is disposed between the inner pot 2 and the pot body 11, and the heating element 3 is used to provide heat energy to the inner pot 2. The stirring element 4 includes a power component 41 and a stirring element 42. The stirring element 42 is disposed in the accommodating cavity S2, and the power component 41 is used to drive the stirring element 42 to rotate. The limiting element 5 and the inner pot 2 enclose a limiting space 51, and the stirring element 42 is disposed within the limiting space 51. The limiting space 51 is used to limit the range of motion of the stirring element 42. Compared to existing technologies, this application, by setting a transparent structure 122 and a limiting component 5, allows users to directly observe the cooking state of the food in the accommodating cavity S2 through the transparent structure 122, so as to determine whether it is necessary to stir or add seasonings, thereby improving the convenience of using the device and achieving better cooking results; the limiting space 51 restricts the stirring component 42, and the movement range of the stirring component 42 is limited to the limiting space 51, so that when the food is taken out, the stirring component 42 can be avoided, solving the problem that the stirring component 42 is difficult to separate from the food.
