Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of kitchen appliances, and particularly relates to a stew pot. BACKGROUND

[0002] The stew pot comprises an outer pot and an inner pot arranged in the outer pot, in order to make the stewed food more nutritious and delicious, more and more stew pots are provided with an inner pot made of ceramic material, but the ceramic material is fragile and has poor wear resistance, and the inner pot is prone to collision during taking and placing, thereby causing a high risk of damage or breakage of the inner pot.

[0003] In addition, after cooking, the user often directly uses the inner pot as tableware and places it on the table, but the temperature of the inner pot is very high, in order to avoid the inner pot scalding the table, the user usually places a heat insulation pad under the inner pot. Although this method can avoid the high-temperature inner pot scalding the table, it has many inconveniences in use. First, the heat insulation pad and the inner pot are independent and separate structures, when the user moves and adjusts the position of the inner pot, the friction between the heat insulation pad and the table is large, the inner pot is prone to relative movement with the heat insulation pad, thereby causing the inner pot to slip off the heat insulation pad. If the user adjusts the position by lifting the inner pot, the heat insulation pad also needs to be moved separately, and in the state of holding the inner pot with both hands, the heat insulation pad can only be moved by others. Therefore, during the meal, the position adjustment of the inner pot is inconvenient. Moreover, since the heat insulation pad and the inner pot are separate, the heat insulation pad needs to be stored separately, and in the long-term use process, the heat insulation pad is prone to be lost.

[0004] Therefore, in the prior art, some stew pots set the heat insulation pad at the bottom of the inner pot, so that the heat insulation pad and the inner pot are fixed as a whole, thereby avoiding the inconvenience caused by the separate taking and placing and use of the heat insulation pad. However, the heat insulation pad is fixed at the bottom of the inner pot, which means that during cooking, the heat insulation pad is also located at the bottom of the inner pot, and the presence of the heat insulation pad will block a part of the heat transferred to the inner pot, thereby greatly reducing the heating efficiency of the heating device on the inner pot, greatly increasing the stewing time, and affecting the use experience. TECHNICAL SOLUTION

[0017] The heating boss has a heating surface for contacting the heating area, and the area of the heating surface is smaller than the area of the heating area, so that there is a gap between the heat insulation and anti-skid member and the heating boss.

[0018] Due to the adoption of the above technical scheme, the stew pot has the following beneficial effects:

[0019] 1. The utility model discloses a ceramic inner bag's bottom wall protrudes with the support muscle, when ceramic inner bag is taken out, through the support muscle to ceramic inner bag is supported, and the heat -proof antiskid piece is arranged in the support surface of support muscle, so that the heat -proof antiskid piece directly with the desktop contact, and ceramic inner bag will not contact with the desktop, therefore can avoid ceramic inner bag scalds the desktop. The heat -proof antiskid piece also plays the antiskid effect, makes the placement of ceramic inner bag more stable, avoids the skidding. And when moving ceramic inner bag, because the heat -proof antiskid piece is fixed to the support muscle, therefore will follow ceramic inner bag together moves, and then need not separately adjust the position of heat -proof antiskid piece, and ceramic inner bag and the heat -proof antiskid piece will not happen relative motion, make the position of heat -proof antiskid piece relative to ceramic inner bag is more stable. Meanwhile, when carrying out the heat -proof antiskid design of ceramic inner bag bottom, need not design the whole bottom surface, just need to set up the heat -proof antiskid piece in the support surface of support muscle pertinently, when guaranteeing the heat -proof antiskid effect, also can reduce the material, to save the cost.

[0020] In addition, during the cooking process, although the heat -proof antiskid piece is still fixed to the support muscle, but the support muscle is surrounded by the bottom wall of the ceramic inner bag to form a heating area, and the heat -proof antiskid piece will not cover the heating area, and the bottom of the accommodating cavity is provided with a raised heating boss, so that the heating boss can directly contact the heating area to heat the ceramic inner bag, so that the heat -proof antiskid piece will not affect the heating efficiency of the ceramic inner bag, ensuring high heating efficiency. And the support muscle is at least partially wrapped around the outer periphery of the heating area, which can also block the heat in the heating area, reduce the spread of heat to the outside, concentrate the heat in the heating area, improve the heating efficiency, and is more advantageous for the ceramic inner bag.

As a preferred embodiment of the utility model, the support rib has an inner side wall close to the heating area and an outer side wall away from the heating area, and the inner side wall and the outer side wall are both provided with fixing grooves, and the fixing parts are respectively provided with fixing protrusions corresponding to the fixing grooves. The heat insulation and anti-skid part is sleeved on the support rib, and the fixing parts on both sides are provided with fixing protrusions and are matched with the fixing grooves of the inner side wall and the outer side wall respectively. Both sides of the fixing parts can form a stop with the side wall of the support rib, thereby limiting the relative movement of the ceramic liner and the heat insulation and anti-skid part in any direction in the horizontal plane. Moreover, during the cooking process, the fixing part on the inner side of the support rib is affected by the heat in the heating area and is expanded by heat, thereby increasing the volume of the fixing protrusion on this side, and forming an interference fit with the fixing groove of the inner side wall, pressing the inner wall of the fixing groove, increasing the friction between the two, making the contact between the two more closely, and further reducing the probability of the heat insulation and anti-skid part falling off the support rib during the cooking process.

[0023] 4. As a preferred embodiment of the utility model, the support rib is in a ring structure to surround the outer periphery of the heating area, and the heat insulation and anti-skid part is in a ring structure and is arranged on the support surface. The support surface surrounds the heating area, which not only enables the support rib to stably support the ceramic liner and ensures that the ceramic liner is placed stably, but also limits the heat in the heating area to the inner side of the support rib, so that the heat is concentrated and gathered, which is beneficial to improving the temperature rising speed of the ceramic liner and improving the heating efficiency. In addition, the heat insulation and anti-skid part is also in a ring shape and is arranged on the ring-shaped support surface, which not only ensures the heat insulation and anti-skid effect, but also makes the lower end of the support rib have the same height in one circumferential circle, thereby making the ceramic liner more stable when placed, and avoiding shaking.

[0024] 5. As a preferred embodiment of the utility model, the bottom wall of the ceramic liner includes a horizontal part and an arc-shaped transition part surrounding the outer periphery of the horizontal part, and the support rib is arranged on the arc-shaped transition part to form a heating area. The support rib is arranged on the arc-shaped transition part, which makes the arrangement position of the support rib closer to the outer edge of the bottom wall of the ceramic liner, thereby stably supporting the ceramic liner. At the same time, the support rib arranged on the arc-shaped transition part does not occupy the horizontal part area, thereby making the horizontal part of the bottom of the ceramic liner form a heating area completely, increasing the contact area between the heating boss and the ceramic liner, maximizing the heating area, and improving the heating efficiency.

[0041] As Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown in the figure, a stew pot, comprising an outer pot 1 with a containing cavity 11, and a ceramic inner container 2 placed in the containing cavity 11, the bottom wall of the ceramic inner container 2 is provided with a support rib 22, the support rib 22 surrounds a heating area 21 on the bottom wall of the ceramic inner container 2, the bottom of the containing cavity 11 is provided with an upwardly protruding heating boss 12, the heating boss 12 is in contact with the heating area 21 to heat the ceramic inner container 2, the lower end of the support rib 22 has a support surface 221, and the stew pot further comprises a heat insulation and anti-skid member 3, which is arranged on the support surface 221.

[0042] It should be noted that, in the utility model, the ceramic inner container 2 is a general term for ceramic inner containers and porcelain inner containers, and the material of the inner container can be ceramic, porcelain and purple sand, etc. in specific applications, which are not limited here. Due to the characteristics of easy breakage, slow heating and good heat preservation, the heating efficiency during heating and the placement after taking out have higher requirements.

[0043] The utility model discloses a ceramic inner bag 2's bottom wall is provided with the support muscle 22, when ceramic inner bag 2 is taken out, through the support muscle 22 to ceramic inner bag 2 is supported, and the heat -proof antiskid piece 3 is arranged on the support surface 221 of support muscle 22, so that the heat -proof antiskid piece 3 directly contacts with the table top, and ceramic inner bag 2 will not contact with the table top, thus can avoid ceramic inner bag 2 scalds the table top.

[0044] In addition, during the cooking process, although the heat -proof antiskid piece 3 is still fixed to the support muscle 22, the support muscle 22 is surrounded by the bottom wall of the ceramic inner bag 2 to form a heating area 21, and the heat -proof antiskid piece 3 will not cover the heating area 21, and the bottom of the accommodating cavity 11 is provided with a raised heating boss 12, so that the heating boss 12 can directly contact with the heating area 21 to heat the ceramic inner bag 2, so that the heat -proof antiskid piece 3 will not affect the heating efficiency of the ceramic inner bag 2, and ensure high heating efficiency. And the support muscle 22 is at least partially around the outer periphery of the heating area 21, which can also block the heat in the heating area 21, reduce the diffusion of heat to the outside, concentrate the heat in the heating area 21, improve the heating efficiency, and is more advantageous for the ceramic inner bag 2.

[0045] Furthermore, due to the weight of the ceramic inner bag 2 is heavy, the support muscle 22 protrudes from the bottom wall of the ceramic inner bag 2, and the heat -proof antiskid piece 3 is arranged on the support muscle 22, whether it is during the process of placing the ceramic inner bag 2 into the outer pot 1 or during the process of placing the ceramic inner bag 2 on the table top, the impact force generated when the support muscle 22 collides with the object below can be alleviated, greatly reducing the risk of the ceramic inner bag 2 being damaged by impact, and prolonging the service life of the ceramic inner bag 2.

[0046] Preferably, the heat -proof antiskid piece 3 is made of silica gel material, which has good high temperature resistance and anti -skid performance, and the cost is relatively low.

[0047] Preferably, the heat insulation and anti-skid piece 3 has a contact surface located at the supporting surface 221, it is to be noted that the present application does not limit the relative area size of the contact surface and the supporting surface 221, in one embodiment, the area of the contact surface is smaller than that of the supporting surface 221, so that the heat insulation and anti-skid piece 3 covers part of the supporting surface 221, since the contact surface is located below the supporting surface 221, when the ceramic liner 2 is placed, the contact surface is still in contact with the tabletop, and the use of the heat insulation and anti-skid piece 3 can be saved, and the cost can be saved. In another embodiment, the area of the contact surface is not less than that of the supporting surface 221, so that the contact surface completely covers the supporting surface 221, so as to improve the heat insulation and anti-skid effect, and when the ceramic liner 2 is dragged transversely, the supporting surface 221 and the contact surface slide relative to each other, the contact surface can still protect the supporting surface 221.

[0048] The present application does not limit the relative position of the heat insulation and anti-skid piece 3 and the supporting rib 22, in one embodiment, the heat insulation and anti-skid piece 3 is arranged on the supporting surface 221, that is, the heat insulation and anti-skid piece 3 is arranged only on the bottom of the supporting rib 22, and the side of the supporting rib 22 is not provided with the heat insulation and anti-skid piece 3. In another embodiment, as shown in Figure 2 、 Figure 4 The heat insulation and anti-skid piece 3 is arranged on the outside of the supporting rib 22, so as to have a supporting portion 31 covering the supporting surface 221, and a fixing portion 32 arranged on the side wall of at least one side of the supporting rib 22.

[0049] The heat insulation and anti-skid piece 3 not only has the supporting portion 31 covering the supporting surface 221, but also has the fixing portion 32 located at the side wall of at least one side of the supporting rib 22, on the one hand, the heat insulation and anti-skid piece 3 can wrap the bottom surface and at least one side surface of the supporting rib 22, and then the heat insulation and anti-skid piece 3 can be fixed to the outside of the supporting rib 22 in a sleeved manner, which reduces the installation difficulty and disassembly difficulty of the heat insulation and anti-skid piece 3, facilitates installation, and also facilitates the user to quickly disassemble and clean the heat insulation and anti-skid piece 3. On the other hand, the fixing portion 32 can be stopped by the side wall of the supporting rib 22, thereby limiting the movement of the heat insulation and anti-skid piece 3 relative to the supporting rib 22, when the ceramic liner 2 is transversely dragged, the ceramic liner 2 and the heat insulation and anti-skid piece 3 tend to move transversely relative to each other, but the fixing portion 32 will be stopped by the side wall of the supporting rib 22, thereby limiting the relative movement of the two, so that the heat insulation and anti-skid piece 3 moves together with the ceramic liner 2, and the relative position stability of the two is ensured.

[0050] Preferably, as shown in Figure 4As shown, the fixing portion 32 is two and corresponds to the inner and outer side walls 223 of the support rib 22, so that the cross section of the heat insulation and anti-skid piece 3 is U-shaped structure, which can wrap the two side walls and the lower part of the support rib 22, improve the protection performance and the convenience of disassembly. Of course, the fixing portion 32 can also be arranged corresponding to the side wall of one side of the support rib 22, for example, the fixing portion 32 corresponds to the inner side wall 222 or the outer side wall 223 of the support rib 22, which is not limited here.

[0051] The present embodiment does not limit the fixing mode of the heat insulation and anti-skid piece 3 and the support rib 22. In a preferred embodiment, as shown in the drawings, Figure 4 As shown, one of the side wall of the support rib 22 and the fixing portion 32 is provided with a fixing protrusion 321, and the other is provided with a fixing groove 224 matched with the fixing protrusion 321, so that the fixing portion 32 is fixed with the support rib 22.

[0052] The fixing protrusion 321 and the fixing groove 224 are matched and clamped, which is more simple to operate, and does not need to be provided with additional fixing structure and fixing piece, which reduces the processing difficulty. And for the ceramic inner container 2, especially the ceramic inner container, it is formed by plastic post-baking, and the protrusion or groove structure can be directly processed and formed in the plastic stage, which is more simple and convenient compared with processing hole structure, thereby further reducing the processing difficulty.

[0053] In addition, the cooperation of the fixing protrusion 321 and the fixing groove 224 can further improve the limiting effect of the fixing portion 32 and the side wall of the support rib 22, preventing the heat insulation and anti-skid piece 3 from falling off the support rib 22.

[0054] Specifically, as shown in the drawings, Figure 4 As shown, the support rib 22 has an inner side wall 222 close to the heating area 21 and an outer side wall 223 away from the heating area 21, and the inner side wall 222 and the outer side wall 223 are both provided with a fixing groove 224, and the fixing portion 32 is provided with a fixing protrusion 321 corresponding to the fixing groove 224.

[0055] The heat insulation and anti-skid piece 3 is sleeved on the support rib 22, and the fixing portions 32 on both sides are provided with fixing protrusions 321 matched with the fixing grooves 224 of the inner side wall 222 and the outer side wall 223, respectively. Not only can the fixing portions 32 on both sides form a stop with the side wall of the support rib 22, thereby limiting the relative movement of the ceramic inner container 2 and the heat insulation and anti-skid piece 3 in any direction in the horizontal plane. Moreover, during cooking, the fixing portion 32 inside the support rib 22 is affected by the heat in the heating area 21 and expands, thereby increasing the volume of the fixing protrusion 321 on that side, forming an interference fit with the fixing groove 224 of the inner side wall 222, extruding the inner wall of the fixing groove 224, increasing the friction between them, making the contact between them more closely, and further reducing the probability of the heat insulation and anti-skid piece 3 falling off the support rib 22 during cooking.

[0056] In another embodiment of the present application, the heat insulation and anti-skid member 3 is fixedly attached to the support surface 221. The heat insulation and anti-skid member 3 is fixed more simply and conveniently, and the fixing position is more flexible, improving the adaptability, and the heat insulation and anti-skid member 3 can be applied to more types of ceramic inner containers 2.

[0057] In another embodiment of the present application, the support surface 221 is provided with a fixing hole, the heat insulation and anti-skid member 3 comprises a contact portion and a fixing portion, the fixing portion extends into the fixing hole to make the heat insulation and anti-skid member 3 and the support rib 22 fit tightly, and the contact portion is located on the lower side of the support surface 221.

[0058] In the present embodiment, the fixing portion of the heat insulation and anti-skid member 3 is inserted into the fixing hole to realize the interference fit, and then the heat insulation and anti-skid member 3 is fixed with the support rib 22. During the heating process, the fixing portion is heated and expands, and then the volume of the fixing portion increases, so that the fixing portion extrudes the inner wall of the fixing hole, and the contact between the fixing portion and the support rib 22 is more closely, the friction is greater, and the fixing stability of the heat insulation and anti-skid member 3 and the support rib 22 is improved.

[0059] It should be noted that the structure of the support rib 22 is not limited in the present application, and it can be one of the following embodiments:

[0060] Embodiment one: in the present embodiment, as shown in Figure 5 , the support rib 22 is an annular structure to surround the outer periphery of the heating area 21.

[0061] The support surface 221 surrounds the heating area 21, which not only enables the support rib 22 to stably support the ceramic inner container 2 and ensure that the ceramic inner container 2 is placed stably, but also limits the heat in the heating area 21 to the inside of the support rib 22, so that the heat is concentrated and gathered, which is beneficial to improve the temperature rising speed of the ceramic inner container 2 and improve the heating efficiency.

[0062] The structure and arrangement of the heat insulation and anti-skid member 3 are not limited in the present embodiment, and in one embodiment, as shown in Figure 5 , Figure 6 , the heat insulation and anti-skid member 3 is an annular structure and is arranged on the support surface 221.

[0063] The heat insulation and anti-skid member 3 is also annular and arranged on the annular support surface 221, which ensures the heat insulation and anti-skid effect, and also makes the lower ends of the support rib 22 have the same height in one circumferential circle, so that the ceramic inner container 2 is placed more stably and avoids shaking.

[0064] In another embodiment, the plurality of heat insulation and anti-skid members 3 are arranged at intervals on the support surface 221. The heat insulation and anti-skid members 3 cover at least part of the support surface 221 along the circumference of the ceramic inner container 2. When the ceramic inner container 2 is placed, the heat insulation and anti-skid members 3 are in contact with the tabletop, thereby ensuring the heat insulation and anti-skid effects while saving the amount of the heat insulation and anti-skid members 3 to reduce the cost.

[0065] In the embodiment, the heat insulation and anti-skid members 3 can be arc-shaped segments or a plurality of convex structures arranged at intervals, which are not limited herein.

[0066] In the embodiment, the plurality of support ribs 22 are arranged at intervals along the circumference of the heating area 21, and the heat insulation and anti-skid members 3 are arranged one by one corresponding to the support ribs 22.

[0067] The support ribs 22 are arranged at intervals on the bottom wall of the ceramic inner container 2. On the one hand, the support ribs 22 ensure the support effect on the ceramic inner container 2. On the other hand, in the heating process, the support ribs 22 not only block the heat in the heating area 21 to concentrate part of the heat in the heating area 21, but also allow part of the heat to flow outward through the gaps 121 between adjacent two support ribs 22 to heat the area outside the support ribs 22 on the bottom of the ceramic inner container 2 and the side of the ceramic inner container 2, thereby making the heat distribution on the ceramic inner container 2 more uniform and improving the heating uniformity.

[0068] Further, in an embodiment of the embodiment, each support rib 22 extends along the circumference of the ceramic inner container 2 in an arc-shaped segment, and adjacent two support ribs 22 have a heat transfer gap 121 therebetween.

[0069] The support rib 22 extends along the circumference of the ceramic inner container 2 in an arc shape, which can increase the area of the support surface 221 to improve the support stability of the ceramic inner container 2.

[0070] In another embodiment of the embodiment, the support rib 22 is a support leg arranged at intervals uniformly along the circumference of the heating area 21.

[0071] Preferably, the number of the support legs is at least three. Taking three support legs as an example, the line connecting the three support legs forms an equilateral triangle. Of course, the number of the support legs can be other numbers, which are not limited herein. In addition, the cross section of the support leg can be cylindrical, square, triangular or other shapes, which are not limited herein.

[0072] Preferably, as shown in Figure 3 , Figure 5 The bottom wall of the ceramic inner container 2 includes a horizontal portion 23 and an arc-shaped transition portion 24 surrounding the outer circumferential side of the horizontal portion 23, and the support rib 22 is arranged on the arc-shaped transition portion 24 to form the heating area 21 on the horizontal portion 23.

[0073] The support rib 22 is located at the arc-shaped transition portion 24. On the one hand, this allows the support rib 22 to be positioned closer to the outer edge of the bottom wall of the ceramic inner liner 2, thus providing more stable support for the ceramic inner liner 2. On the other hand, since the support rib 22 is located at the arc-shaped transition portion 24, it does not occupy the horizontal portion 23 area. This ensures that the entire horizontal portion 23 at the bottom of the ceramic inner liner 2 constitutes the heating area 21, increasing the contact area between the heating boss 12 and the ceramic inner liner 2, maximizing the heated area, and improving heating efficiency.

[0074] Specifically, the heating device is located on the lower side of the heating boss 12. The heat from the heating device is first transferred to the heating boss 12 and then to the ceramic inner liner 2.

[0075] Preferably, such as Figure 1 As shown, the heating boss 12 has a heating surface for contacting the heating area 21. The area of ​​the heating surface is smaller than the area of ​​the heating area 21, so that there is a gap 121 between the heat-insulating anti-slip member 3 and the heating boss 12. The heating surface is smaller than the area of ​​the heating area 21, so that there is a gap 121 between the supporting rib 22 and the side wall of the heating boss 12. This avoids direct contact between the heating boss 12 and the heat-insulating anti-slip member 3 while ensuring heating efficiency, reduces the temperature rise of the heat-insulating anti-slip member 3, and prevents the high-temperature heating boss 12 from directly contacting the heat-insulating anti-slip member 3 for heat transfer, which could lead to melting or damage, thus improving the service life of the heat-insulating anti-slip member 3.

[0076] Specifically, such as Figure 2 As shown, the sidewall of the heating boss 12 extends obliquely so that the width of the heating boss 12 gradually decreases from bottom to top, and the support rib 22 is located on the outside of the heating boss 12.
