Description

Technical Field

[0001] The utility model relates to the field of small household appliances, in particular to a cooking utensil. Background Art

[0002] Cooking utensils, such as electric steamers or electric stew pots, usually include an inner pot and a water tank with a heating element. The inner pot is placed in the water tank, and the heating element generates steam by heating the water tank to heat the food in the inner pot. Due to the long cooking time, it can provide heat evenly, which can make the nutrients in the food more fully precipitate. However, when the water in the water tank is not filled with enough water or the cooking time is too long, the existing cooking utensils may cause the cooking utensils to dry burn because they are not equipped with anti-dry burning elements, which poses a great safety hazard.

[0003] Patent CN217118139U discloses an electric stew pot with a water retaining boss at the bottom of the water tank, near the electric heating plate, and a sealing member is provided between the heating element and the water retaining boss, and the highest point of the water retaining boss is higher than the bottom of the water tank. Although this method will retain some water at the bottom of the water tank in the case of dry boiling, since most of the structure of the water retaining boss is in a state without water coverage, when dry boiling occurs, the temperature of the water retaining boss of the plastic structure will still be high, and there is still a great safety hazard. Utility Model Content

[0004] In view of this, it is necessary to provide a cooking utensil to reduce the potential safety hazards in view of the above problems.

[0005] The utility model provides a cooking utensil, comprising an inner pot and a base assembly, wherein the base assembly comprises: a water tank, a bottom wall of which is provided with a mounting hole; a base, on which the water tank is mounted; and a heating assembly, which is fixed to the base and mounted in the mounting hole, wherein the heating assembly comprises a heating plate and a sealing member, wherein the sealing member is arranged around the outer peripheral surface of the heating plate; wherein the sealing member comprises a sealing portion and an annular water retaining portion located at the top end of the sealing portion, wherein the sealing portion is sealingly connected to the wall of the mounting hole, and the water retaining portion is higher than the bottom wall of the water tank.

[0006] In the above cooking utensil, the sealing member can ensure the sealing between the water tank and the heating plate, and prevent the water in the water tank from flowing into the base; when the heating plate is working, the water in the water tank is heated, the water in the water tank will evaporate continuously, and the water level will drop continuously. When the water level drops to the height corresponding to the highest point of the water retaining part, the water retaining part separates the water in the water tank into two parts; when the heating plate continues to work, the heating plate only heats the water in the space surrounded by the inner wall of the water retaining part and the heating plate, and will not affect the water in the annular space surrounded by the outer wall of the water retaining part and the bottom wall and side walls of the water tank. Even if the water in the space surrounded by the inner wall of the water retaining part and the heating plate is dried up, water is still left in the annular space surrounded by the outer wall of the water retaining part and the bottom wall and side walls of the water tank, and the water will not flow to the heating plate, and the bottom wall of the water tank can always be in contact with the water, so as to avoid the phenomenon of dry burning due to the water tank being in a state without water covering, and the water can also reduce the temperature of the bottom wall of the water tank, avoid the temperature of the water tank being too high, and reduce the safety hazard.

[0007] In one embodiment, the height difference between the water retaining portion and the bottom wall of the water tank is H, and satisfies: H≥1.5mm.

[0008] This arrangement ensures that the water level in the annular space surrounded by the outer wall of the water retaining part and the bottom wall and side walls of the water tank is not lower than 1.5 mm, and water will not flow to the heating plate, thereby ensuring that there is enough water to effectively cool the bottom wall of the water tank.

[0009] In one of the embodiments, a step portion is formed between the sealing portion and the water retaining portion, and the step portion is located on a side close to the bottom wall of the water tank.

[0010] With such arrangement, the step portion enables the bottom wall of the water tank to be completely covered by water, thereby improving the cooling effect of water on the bottom wall of the water tank and reducing safety hazards.

[0011] The bottom wall of the water tank includes an outer ring wall and an inner ring wall smoothly connected to the outer ring wall, the mounting hole is opened in the inner ring wall, and the upper surface of the inner ring wall extends obliquely upward from the edge of the mounting hole toward the outer ring wall.

[0012] With this arrangement, the surface of the inner ring wall is lower than that of the outer ring wall, which is conducive to storing more water at the position of the inner ring wall. Since the inner ring wall is closer to the heating plate, more water is conducive to preventing the bottom wall of the water tank from drying out.

[0013] In one embodiment, the sealing portion and the water retaining portion are integrally formed.

[0014] Such an arrangement facilitates the production and processing of the sealing component, and ensures the tightness and reliability of the connection between the sealing part and the water retaining part.

[0015] In one embodiment, the base assembly further includes a pressure plate, and the pressure plate presses the sealing member to seal between the water tank and the heating assembly.

[0016] With this arrangement, the pressure plate is used to press and fix the seal between the water tank and the heating plate to ensure the sealing effect of the seal; at the same time, the separate arrangement of the pressure plate and the water tank can also facilitate the disassembly or replacement of the seal, reducing the heat transferred from the heating plate through the pressure plate to the bottom wall of the water tank.

[0017] In one embodiment, the heating plate includes a heating part and a plate edge arranged on the periphery of the heating part; the sealing part includes a first sealing section and a second sealing section, the top of the first sealing section is provided with the water retaining part, the bottom end of the first sealing section is connected to the second sealing section, the first sealing section surrounds the periphery of the heating part, the second sealing section has a receiving groove, and the plate edge is located in the receiving groove.

[0018] With this arrangement, the disk edge is located in the receiving groove to ensure the sealing between the seal and the heating disk, while limiting the relative position of the heating disk and the seal; the pressure plate can press and fix the disk edge and the second sealing section to the bottom surface of the bottom wall of the water tank, ensuring the stability and reliability of the connection between the components and facilitating user assembly and disassembly.

[0019] In one embodiment, the outer peripheral surface of the heating part is sealed to the side wall of the mounting hole via the first sealing section; and / or the top surface of the disk edge is sealed to the bottom surface of the bottom wall of the water tank via the second sealing section.

[0020] With such arrangement, the first sealing section ensures the sealing between the heating part and the water tank; the second sealing section ensures the sealing between the pan edge and the water tank.

[0021] In one embodiment, an annular convex rib is provided on the first sealing section; and / or an annular convex rib is provided on the second sealing section.

[0022] With such a configuration, the convex rib can increase the deformation capacity of the first sealing section and / or the second sealing section, so that the first sealing section and / or the second sealing section can fully fit with the heating plate and the water tank, thereby increasing the contact area between the water tank, the seal and the heating plate, and improving the sealing between the water tank and the heating plate.

[0023] In one embodiment, the thickness L of the water retaining portion satisfies: 0.5 mm ≤ L ≤ 2 mm.

[0024] Such an arrangement can ensure the strength of the water retaining part and facilitate the production of the seal; at the same time, it can avoid the water retaining part being too large and occupying too much space on the bottom wall of the water tank, thereby ensuring a neat appearance.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a central component at the same time. When a component is considered to be "fixed to" another component, it may be directly fixed on the other component or there may be a central component at the same time.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0037] Cooking utensils, such as electric steamers or electric stew pots, usually include an inner pot and a water tank with a heating element. The inner pot is placed in the water tank, and the heating element generates steam by heating the water tank to heat the food in the inner pot. Due to the long cooking time, it can provide heat evenly, which can make the nutrients in the food more fully precipitate. However, when the water in the water tank is not filled with enough water or the cooking time is too long, the existing cooking utensils may cause the cooking utensils to dry burn because they are not equipped with anti-dry burning elements, which poses a great safety hazard.

[0038] In order to solve the above problems, Figures 1 to 8 As shown, the present application provides a cooking utensil, which can prevent the temperature of the water tank from being too high and reduce safety hazards. The cooking utensil can be applied as an electric steamer, an electric stew pot, etc.

[0039] like Figures 1 to 3 As shown, specifically, the cooking utensil includes an inner pot 200 and a base assembly 100, the base assembly 100 includes a water tank 10, a base 20 and a heating assembly 30, the bottom wall of the water tank 10 is provided with a mounting hole 11, the water tank 10 is mounted on the base 20; the heating assembly 30 is fixed to the base 20 and mounted in the mounting hole 11, the heating assembly 30 includes a heating plate 31 and a sealing member 32, the sealing member 32 is arranged around the outer circumference of the heating plate 31. The water tank 10 has an upward opening, the water tank 10 and the heating plate 31 form a heating space for holding water, the sealing member 32 can ensure the sealing between the water tank 10 and the heating plate 31, and prevent the water in the water tank 10 from flowing into the base 20 from the gap between the water tank 10 and the heating assembly 30. During the cooking process, the heating plate 31 heats the water in the water tank 10, and uses the water as a heat transfer medium, and the heated water transfers the heat to the inner pot 200 to heat the food in the inner pot 200.

[0040] like Figures 4 to 5As shown, the sealing member 32 includes a sealing portion 321 and an annular water retaining portion 322 located at the top of the sealing portion 321 , the sealing portion 321 is sealedly connected to the wall of the mounting hole 11 , and the water retaining portion 322 is higher than the bottom wall of the water tank 10 .

[0041] In the cooking device provided by the utility model, the heating plate 31 heats the water in the water tank 10 when working, the water in the water tank 10 will continue to evaporate, and the water level will continue to drop. When the water level drops to the height corresponding to the highest point of the water retaining portion 322, the water retaining portion 322 divides the water in the water tank 10 into two parts, the first part is the water in the space surrounded by the inner wall of the water retaining portion 322 and the heating plate 31, and the second part is the water in the annular space surrounded by the outer wall of the water retaining portion 322 and the bottom wall and side wall of the water tank 10. When the heating plate 31 continues to work, the heating plate 31 only heats the water in the first part, and the water level of the first part of the water continues to drop, without affecting the water in the second part, so the water level of the second part of the water remains unchanged.

[0042] That is to say, since the sealing member 32 is disposed between the heating plate 31 and the bottom wall of the water tank 10, and the water retaining portion 322 is disposed at the top of the sealing portion 321, even if the water in the space surrounded by the inner wall of the water retaining portion 322 and the heating plate 31 is dried up, water still remains in the annular space surrounded by the outer wall of the water retaining portion 322 and the bottom wall and side wall of the water tank 10, and the water will not flow to the heating plate 31. Therefore, the bottom wall of the water tank 10 can always be in contact with water, thereby preventing the water tank 10 from being in a water-free state and causing dry burning, and the water can also lower the temperature of the bottom wall of the water tank 10, thereby preventing the temperature of the water tank 10 from being too high and reducing safety hazards.

[0043] The cooking utensil may also be an electric stew pot or other cooking utensil that heats the water tank to generate steam through a heating element, thereby heating the food in the inner pot 200. The inner pot 200 may be a pot body placed in the water tank 10, or a steamer mounted above the water tank 10. In addition, the base 20 includes a detachably connected side wall 21 and a bottom wall 22, so that the user can install other components in the base 20 such as the heating assembly 30.

[0044] like Figures 2 to 3 As shown, the mounting hole 11 is opened at the center of the bottom wall of the water tank 10 and is set as a circular through hole, which is convenient for production and assembly, and also ensures the heating effect of the heating plate 31 on the water in the water tank 10. The sealing member 32 is set in an annular shape, and the sealing part 321 and the water retaining part 322 are both set in corresponding annular structures to ensure the sealing effect and the water retaining effect.

[0045] like Figure 5 and Figure 8As shown, the height difference between the water retaining portion 322 and the bottom wall of the water tank 10 is H, and satisfies: H ≥ 1.5 mm. In other words, the highest point of the water retaining portion 322 is at least 1.5 mm higher than the lowest point of the bottom wall of the water tank 10, wherein the highest point of the water retaining portion 322 can be 1.5 mm, 1.6 mm, 1.7 mm, 2 mm, 3 mm, or any other value greater than or equal to 1.5 mm higher than the lowest point of the bottom wall of the water tank 10. In this way, the water separation effect in the water tank 10 can be ensured, and the water level in the annular space surrounded by the outer wall of the water retaining portion 322 and the bottom wall and side wall of the water tank 10 is ensured not to be lower than 1.5 mm, and the water will not flow to the heating plate 31, thereby ensuring that there is enough water to effectively cool the bottom wall of the water tank 10.

[0046] In the illustrated embodiment, after the heating assembly 30 is installed in the mounting hole 11, the top of the sealing portion 321 is flush with the bottom wall of the water tank 10. At this time, the height between the top of the water retaining portion 322 and the top of the sealing portion 321 is the height difference H between the water retaining portion 322 and the bottom wall of the water tank 10, and the height between the top of the water retaining portion 322 and the top of the sealing portion 321 is greater than or equal to 1.5 mm. Among them, the top of the water retaining portion 322 can be 1.5 mm, 1.6 mm, 1.7 mm, 2 mm, 3 mm, etc., whichever is greater than or equal to 1.5 mm. The top of the sealing portion 321 is flush with the bottom wall of the water tank 10 to ensure the sealing effect of the sealing portion 321 between the water tank 10 and the heating plate 31, and also to ensure the appearance of the base assembly 100 is regular.

[0047] like Figure 5 As shown, the bottom wall of the water tank 10 can be a plane, the top of the sealing portion 321 is flush with the plane, and the water retaining portion 322 protrudes from the plane; or, the bottom wall of the water tank 10 can also be gradually inclined downward from the outside to the inside as shown in the figure, that is, the connection between the water tank 10 and the sealing member 32 is the lowest point of the bottom wall of the water tank 10, and the top of the sealing portion 321 is flush with the lowest point of the bottom wall of the water tank 10. Since the connection between the water tank 10 and the sealing member 32 is close to the heating plate 31, the liquid level height of the area of ​​the water tank 10 close to the heating plate 31 can be ensured, and the cooling effect of water on the area of ​​the water tank 10 close to the heating plate 31 can be improved. At the same time, it can also prevent the water retaining portion 322 from protruding excessively from the bottom wall of the water tank 10 to affect the heating efficiency of the water in the water tank 10, thereby affecting the heating effect of the inner pot 200.

[0048] Specifically, the bottom wall of the water tank 10 includes an outer annular wall 12 and an inner annular wall 13 smoothly connected to the outer annular wall. The mounting hole 11 is opened on the inner annular wall 13. The upper surface of the inner annular wall 13 extends upwardly from the edge of the mounting hole 11 toward the outer annular wall 12. The surface of the inner annular wall 13 is lower than the outer annular wall 12, which is conducive to storing more water at the position of the inner annular wall 13. Since the inner annular wall 13 is closer to the heating plate 31, more water is conducive to preventing the bottom wall of the water tank 10 from drying out.

[0049] Of course, in other embodiments, after the heating component 30 is installed in the mounting hole 11, there may be a height difference between the top of the sealing portion 321 and the bottom wall of the water tank 10. For example, the top of the sealing portion 321 is slightly higher or slightly lower than the bottom wall of the water tank 10. As long as the sealing performance of the sealing portion 321 is guaranteed and the top of the water retaining portion 322 is higher than the bottom wall of the water tank 10, water can always remain in the annular space surrounded by the outer wall of the water retaining portion 322 and the bottom wall and side wall of the water tank 10.

[0050] like Figure 8 As shown, the thickness L of the water retaining portion 322 satisfies: 0.5mm≤L≤2mm. Among them, the thickness L of the water retaining portion 322 is the radial dimension of the water retaining portion 322 along the base assembly 100. The thickness L of the water retaining portion 322 can be any value within the range of 0.5mm to 2mm, such as 0.5mm, 0.6mm, 0.7mm, 1mm, 1.5mm, 2mm, etc. The thickness L of the water retaining portion 322 ≥ 0.5mm can ensure the strength of the water retaining portion 322, and it is also convenient to produce the seal 32. The thickness L of the water retaining portion 322 ≤ 2mm can avoid the size of the water retaining portion 322 being too large and occupying too much space on the bottom wall of the water tank 10, and ensure a neat appearance.

[0051] like Figures 5 to 8 As shown, a step portion 323 is formed between the sealing portion 321 and the water retaining portion 322, and the step portion 323 is located on a side close to the bottom wall of the water tank 10. When the water level drops to a height corresponding to the highest point of the water retaining portion 322, the water retaining portion 322 divides the water in the water tank 10 into two parts, and the second part is the water in the annular space surrounded by the outer wall of the water retaining portion 322, the step portion 323, and the bottom wall and side wall of the water tank 10. The step portion 323 allows the bottom wall of the water tank 10 to be completely covered by water, thereby improving the cooling effect of water on the bottom wall of the water tank 10 and further reducing safety hazards.

[0052] The sealing portion 321 and the water retaining portion 322 are preferably integrally formed to facilitate production and processing of the sealing component 32 and ensure tightness and reliability of the connection between the sealing portion 321 and the water retaining portion 322 .

[0053] like Figure 3 to Figure 4As shown, the base assembly 100 also includes a pressure plate 33, which is pressed against the sealing member 32 to seal the water tank 10 and the heating assembly 30. The pressure plate 33 can be set as an annular structure, and includes a fixing portion 331 and a pressing portion 332 arranged on the inner periphery of the fixing portion 331. The fixing portion 331 is used to be fixedly connected to the bottom wall of the water tank 10 by fasteners such as screws and bolts to ensure the stability and reliability of the connection between the pressure plate 33 and the sealing member 32 and the water tank 10; the pressing portion 332 is used to press and fix the sealing member 32 between the water tank 10 and the heating plate 31 to ensure the sealing effect of the sealing member 32. The central area of ​​the pressure plate 33 is used for wiring, which is convenient for the electrical connection between the bottom of the heating plate 31 and other components inside the base 20. The pressure plate 33 and the base 20 are set as a split structure, which can facilitate the disassembly or replacement of the sealing member 32, and is convenient for user operation; at the same time, it can also reduce the heat transferred from the heating plate 31 to the bottom wall of the water tank 10 through the pressure plate 33, thereby reducing safety hazards.

[0054] The seal 32 is made of elastic materials such as silicone or rubber, and can be interference fit with the water tank 10, the heating plate 31 and the pressure plate 33. When the crimping portion 332 presses and fixes the seal 32 between the water tank 10 and the heating plate 31, the water tank 10 and the heating plate 31 can squeeze the seal 32 and deform the seal 32, so that the seal 32 can fit with the water tank 10 and the heating plate 31, thereby improving the sealing between the water tank 10 and the heating plate 31.

[0055] like Figures 5 to 8 As shown, the heating plate 31 includes a heating portion 311 and a plate edge 312 arranged on the periphery of the heating portion 311; the sealing portion 321 includes a first sealing section 3211 and a second sealing section 3212, the top of the first sealing section 3211 is provided with a water retaining portion 322, the bottom of the first sealing section 3211 is connected to the second sealing section 3212, the first sealing section 3211 surrounds the periphery of the heating portion 311, the second sealing section 3212 has a receiving groove 32121, and the plate edge 312 is located in the receiving groove 32121. The plate edge 312 is located in the receiving groove 32121 to fix the heating plate 31 and the sealing portion 321, to ensure the sealing between the sealing member 32 and the heating plate 31, and at the same time limit the relative position of the heating plate 31 and the sealing member 32. When the fixing portion 331 of the pressure plate 33 is fixedly connected to the bottom wall of the water tank 10, the crimping portion 332 of the pressure plate 33 can press and fix the plate edge 312 and the second sealing section 3212 to the bottom surface of the bottom wall of the water tank 10, thereby ensuring the stability and reliability of the connection between the water tank 10, the sealing member 32, the heating plate 31 and the pressure plate 33, and facilitating assembly and disassembly by users.

[0056] like Figure 5As shown, in the illustrated embodiment, the outer peripheral surface of the heating portion 311 and the side wall of the mounting hole 11 are sealed and connected by the first sealing section 3211 to ensure the sealing between the heating portion 311 and the water tank 10. The top surface of the plate edge 312 and the bottom surface of the bottom wall of the water tank 10 are sealed and connected by the second sealing section 3212 to ensure the sealing between the plate edge 312 and the water tank 10. The first sealing section 3211 and the second sealing section 3212 can play a double sealing role, increase the contact area between the heating plate 31, the sealing member 32 and the water tank 10, improve the sealing effect, ensure that the water in the water tank 10 will not flow into the base 20 through the gap between the water tank 10 and the heating portion 311 and the gap between the water tank 10 and the plate edge 312, and ensure that the components in the base 20 can work normally.

[0057] like Figure 8 As shown, specifically, the second sealing section 3212 includes a first section 32122, a second section 32123 and a third section 32124 which are sequentially connected in a U shape and enclose a containing groove 32121, and the second section 32123 is used to connect the first section 32122 and the third section 32124. The top surface of the pan edge 312 and the bottom surface of the bottom wall of the water tank 10 are sealed by the first section 32122, and the crimping portion 332 and the bottom surface of the pan edge 312 are sealed by the third section 32124. At the same time, the third section 32124 can also support and protect the pan edge 312, so as to prevent the crimping portion 332 from directly contacting the pan edge 312 and scratching the pan edge 312.

[0058] Of course, in other embodiments, the outer peripheral surface of the disk edge 312 is sealed to the side wall of the mounting hole 11 by the second sealing section 3212; alternatively, the heating disk 31 and the water tank 10 may be sealed only by the first sealing section 3211 or only by the second sealing section 3212. As long as the sealing between the heating disk 31 and the water tank 10 can be ensured to prevent the water in the water tank 10 from flowing into the base 20 while the components in the base 20 can work normally, the embodiments of the utility model are not specifically limited here.

[0059] like Figure 5 and Figure 8As shown, in one embodiment, both the first sealing section 3211 and the second sealing section 3212 are provided with an annular convex rib 3213. The convex rib 3213 can increase the deformation capacity of the first sealing section 3211 and the second sealing section 3212, so that when the crimping portion 332 presses and fixes the sealing member 32 between the water tank 10 and the heating plate 31, the first sealing section 3211 can be completely fitted with the outer peripheral surface of the heating portion 311 and the side wall of the mounting hole 11, and the first section 32122 of the second sealing section 3212 can be completely fitted with the top surface of the plate edge 312 and the bottom surface of the bottom wall of the water tank 10, thereby increasing the contact area between the water tank 10, the sealing member 32 and the heating plate 31, thereby further improving the sealing between the water tank 10 and the heating plate 31. In another embodiment, only the first sealing section 3211 or only the second sealing section 3212 may be provided with an annular convex rib 3213. In other embodiments, the rib 3213 may also be disposed on the inner wall of the mounting hole 11 .

[0060] The technical features of the above-described embodiments may be arbitrarily combined.
