Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of kitchen furniture, in particular to a cooking stove. Background Art
[0002] There is a type of cooking stove that adopts a stove top and a heating plate that are separately formed and adapted for assembly. For example, in some cooking stoves compatible with a weighing module, a stove hole is opened on the surface of the stove top, and the heating plate is higher than the surface of the stove top and covers the stove hole. Since there is an assembly gap between the edge of the stove hole opening and the heating plate, this type of cooking stove has poor waterproof ability. The soup splashed from the pot during cooking and the cleaning liquid overflowing along the stove surface when cleaning the cooking stove can easily leak into the cooking stove from the stove hole opening and the heating plate, which not only causes pollution in the cooking stove, but also damages the functional components in the cooking stove. Utility Model Content
[0003] In view of this, the utility model provides a cooking stove with a waterproof function, which can prevent soup or cleaning liquid from penetrating to protect internal functional components.
[0004] The cooking stove provided by the utility model comprises:
[0005] A stove top is provided with a stove hole;
[0006] The heating plate is coaxially arranged with the stove hole;
[0007] The waterproof part comprises a first closed loop end, a second closed loop end and a water retaining ring connecting the first closed loop end and the second closed loop end;
[0008] The first closed loop end extends along the stove hole opening and is sealed to connect with the stove, the second closed loop end extends along the outer edge of the heating plate and is sealed to connect with the heating plate, and the water retaining ring continuously surrounds the axis of the heating plate and the stove hole.
[0009] Compared with the prior art, the cooking stove of the utility model blocks the leakage of liquid along the stove table into the stove hole through the first closed loop end, blocks the leakage of liquid along the heating plate into the stove hole through the second closed loop end, and seals the first closed loop end and the second closed loop end through the water retaining ring, which can effectively prevent soup and cleaning liquid from leaking into the cooking stove from between the stove hole opening and the heating plate, thereby having better waterproof ability and providing effective waterproof protection for functional components inside the cooking stove.
[0010] In one embodiment, the water retaining ring includes a first retaining ring and a second retaining ring which are separately arranged, the first retaining ring is integrally connected to the first closed loop end, the second retaining ring is integrally connected to the second closed loop end, and one of the first retaining ring and the second retaining ring is sleeved on the outer circumference of the other.
[0011] With such arrangement, the connection and combination of the waterproof part and the stove, and the waterproof part and the heating plate are simpler and easier.
[0012] In one embodiment, the cooking stove further comprises a stove body supporting a stove top, a stove cavity is defined between the stove top and the stove body, and the heating plate protrudes from a side of the stove top away from the stove body.
[0013] With such arrangement, the cooking stove can carry the cooking pot or food container via the heating plate, and the cooking pot or food container will not burn the stove surface during cooking.
[0014] In one embodiment, a heating element is provided on the side of the heating plate close to the stove cavity, and the water retaining ring also includes a third retaining ring sleeved on the outer periphery of the heating element, the third retaining ring is integrally connected to the second closed loop end, the second retaining ring is sleeved on the outer periphery of the first retaining ring, and the first retaining ring is sleeved on the outer periphery of the third retaining ring.
[0015] With this arrangement, the outer periphery of the second baffle ring forms the outer periphery of the waterproof component, and the inner periphery of the third baffle ring forms the inner periphery of the waterproof component. The gap between the outer periphery and the inner periphery of the waterproof component is more tortuous and complex, and the difficulty of liquid leakage and adhesion to the heating component is increased, thereby improving the waterproof ability of the heating component.
[0016] In one embodiment, the cooking stove further includes a sub-chassis arranged in the stove cavity, the sub-chassis includes a support portion facing the heating plate, one end of the third baffle ring away from the second closed loop end is connected to the support portion, and one end of the heating element away from the heating plate is connected to the support portion.
[0017] With such arrangement, the third baffle ring and the heating element both achieve respective axial positioning through the support portion, whereby the third baffle ring and the heating element can remain relatively fixed in the axial direction, thereby enabling the third baffle ring to effectively prevent liquid from leaking and overflowing toward the heating element.
[0018] In one embodiment, a fourth annular gap is provided between the outer periphery of the third baffle ring and the inner periphery of the first baffle ring; and / or a fifth annular gap is provided between the inner periphery of the third baffle ring and the outer periphery of the heating element.
[0019] With such arrangement, the fourth annular gap can leave deformation space for the third retaining ring and the first retaining ring as the heating element deforms and expands, thereby avoiding mutual interference between the third retaining ring and the first retaining ring after thermal expansion; the fifth annular gap can leave deformation space between the third retaining ring and the heating element, thereby avoiding mutual interference between the heating element and the third retaining ring after thermal expansion.
[0020] In one embodiment, the water retaining ring further includes a water retaining flange, which is located at one end of the first retaining ring extending into the second retaining ring and protrudes relative to the outer periphery of the first retaining ring.
[0021] With such arrangement, the outer periphery of the second baffle ring forms the outer periphery of the waterproof component, and the inner periphery of the third baffle ring forms the inner periphery of the waterproof component. The gap between the outer periphery and the inner periphery of the waterproof component becomes more tortuous and complex, and the difficulty of liquid leakage and adhesion to the heating component increases. The liquid entering the third annular gap is blocked by the water retaining flange and is difficult to diffuse into the fourth annular gap, thereby improving the waterproof ability of the heating component.
[0022] In one embodiment, the axial length of the third baffle ring is not less than the axial length of the heating element.
[0023] Such an arrangement enables the third baffle ring to effectively prevent the liquid from leaking and overflowing toward the heating element, thereby increasing the difficulty of the liquid adhering to the heating element.
[0024] In one embodiment, a first annular gap is provided between an end of the second baffle ring away from the second closed-loop end and the stove top; and / or, a second annular gap is provided between an end of the first baffle ring away from the first closed-loop end and the heating plate; and / or, a third annular gap is provided between the outer periphery of the first baffle ring and the inner periphery of the second baffle ring.
[0025] With such a configuration, the first annular gap can reserve a deformation space for the second baffle ring to deform and expand after absorbing the heat from the heating plate, thereby avoiding interference between the second baffle ring and the stove after being heated; the second annular gap can reserve a deformation space for the first baffle ring to deform and expand after absorbing the heat from the heating element, thereby avoiding interference between the first baffle ring and the heating plate after being heated; the third annular gap can reserve a deformation space for the first baffle ring and the second baffle ring to deform and expand when heated, thereby avoiding interference between the first baffle ring and the second baffle ring.
[0026] In one embodiment, the first closed loop end is in contact with and sealed against the tabletop of the stove; and / or the second closed loop end is in contact with and sealed against the end surface of the heating plate.
[0027] With such arrangement, the sealed connection between the waterproof part and the stove top, and the sealed connection between the waterproof part and the heating plate are easier to achieve. BRIEF DESCRIPTION OF THE DRAWINGS

The water retaining ring 33 is a closed loop structure located between the first closed loop end 31 and the second closed loop end 32, and continuously surrounds the axis of the heating plate 20 and the stove hole 11.
[0036] See also Figure 1-2 Optionally, the waterproof member 30 is an annular member coaxially arranged with the stove hole 11 and the heating plate 20, and the waterproof member 30 is sleeved on the outer peripheral side of the heating member 40. In other embodiments, the waterproof member 30 does not need to be coaxial with the stove hole 11 and the heating plate 20, as long as the waterproof member 30 is sleeved on the outer peripheral side of the heating member 40.
[0037] See also Figure 1 and Figure 2 In some embodiments, the cooking stove 100 further includes a sub-chassis 60 disposed in the stove cavity 51. The sub-chassis 60 is located at an end of the heating element 40 relatively away from the heating plate 20, and includes a support portion 61 disposed toward the heating plate 20. A portion of the waterproof component 30 and an end of the heating element 40 facing away from the heating plate 20 are both connected to the support portion 61.
[0038] Optionally, see Figure 3 The cooking stove 100 further includes a weighing module (not numbered in the figure) disposed in the stove cavity 51. The weighing module is located on the side of the sub-chassis 60 away from the heating plate 20 and the heating element 40, and is used to weigh the cooking pot or food container placed on the heating plate 20. In order to reserve space for the weighing module, the heating plate 20 protrudes from the side of the stove top 10 away from the stove body 50. The heating element 40 includes an electromagnetic wire coil 41 and a magnetic isolation plate 42 coaxially disposed with the heating plate 20. The electromagnetic wire coil 41 is located between the magnetic isolation plate 42 and the heating plate 20. The support portion 61 is connected to and carries the magnetic isolation plate 42.
[0039] It is understandable that in other embodiments, the heating element 40 does not necessarily include the electromagnetic wire coil 41. The heating element 40 can also be other devices capable of heating the heating plate 20. The heating of the heating plate 20 is not limited to electric heating, but can also be open flame heating.
[0040] In some embodiments, the water retaining ring 33 includes a first retaining ring 331 and a second retaining ring 332 which are separated and coaxially arranged. The first retaining ring 331 is integrally connected to the first closed loop end 31, and the second retaining ring 332 is integrally connected to the second closed loop end 32. One of the first retaining ring 331 and the second retaining ring 332 is sleeved on the outer circumference of the other. Figure 1 and Figure 3The waterproof component 30 includes a first waterproof element 301 and a second waterproof element 302 which are separately formed and coaxially arranged. The first waterproof element 301 includes a first retaining ring 331 and a first closed-loop end 31 , and the second waterproof element 302 includes a second retaining ring 332 and a second closed-loop end 32 .
[0041] Specifically, see Figure 1-2 The water retaining ring 33 also includes a third retaining ring 333 belonging to the second waterproof element 302. The third retaining ring 333, the second retaining ring 332 and the second closed loop end 32 are integrally connected. The second retaining ring 332 is sleeved on the outer periphery of the first retaining ring 331. The first retaining ring 331 is sleeved on the outer periphery of the third retaining ring 333. The third retaining ring 333 is sleeved on the outer periphery of the heating element 40. The outer periphery of the second retaining ring 332 forms the outer periphery of the waterproof element 30, and the inner periphery of the third retaining ring 333 forms the inner periphery of the waterproof element 30.
[0042] Optionally, the third retaining ring 333 is coaxially arranged with the second retaining ring 332, and the heating element 40 is coaxially arranged with the third retaining ring 333. Figure 2 The first closed loop end 31 is in contact with the surface of the stove top 10 away from the stove body 50, and the first stop ring 331 is protruded along the axial direction of the heating plate 20 and the heating element 40 on the side of the first closed loop end 31 away from the stove top 10; the end surface of the heating plate 20 facing the stove cavity 51 and the heating element 40 is in contact with the second closed loop end 32, and the second stop ring 332 and the third stop ring 333 are protruded along the axial direction of the heating plate 20 and the heating element 40 on the side of the second closed loop end 32 away from the heating plate 20.
[0043] Further, see Figure 1-2 The axial length of the third retaining ring 333 is not less than the axial length of the heating element 40, the distance from the end of the third retaining ring 333 away from the heating plate 20 to the bottom of the stove body 50 is less than or equal to the distance from the end of the magnetic isolation plate 42 away from the heating plate 20 to the bottom of the stove body 50, and the end of the third retaining ring 333 away from the heating plate 20 is supported by the support portion 61 of the sub-chassis 60. The end of the magnetic isolation plate 42 away from the electromagnetic wire coil 41 and the heating plate 20 is supported by the support portion 61.
[0044] See also Figure 2A first annular gap 335 is provided between the end of the second retaining ring 332 away from the first closed loop end 31 and the stove 10, a second annular gap 336 is provided between the end of the first retaining ring 331 away from the first closed loop end 31 and the heating plate 20, a third annular gap 337 is provided between the outer periphery of the first retaining ring 331 and the inner periphery of the second retaining ring 332, a fourth annular gap 338 is provided between the outer periphery of the third retaining ring 333 and the inner periphery of the first retaining ring 331, and a fifth annular gap 339 is provided between the inner periphery of the third retaining ring 333 and the outer periphery of the heating element 40. Along the radial direction of the heating plate 20 and away from the axis of the heating plate 20, the heating element 40, the fifth annular gap 339, the third retaining ring 333, the fourth annular gap 338, the first retaining ring 331, the third annular gap 337 and the second retaining ring 332 are provided in sequence.
[0045] With such arrangement, soup, cleaning liquid and other liquids located on the periphery of the second baffle ring 332 will find it more difficult to penetrate into the stove hole 11 , and the third annular gap 337 , the fourth annular gap 338 and the fifth annular gap 339 are more tortuous, so it is also more difficult for liquid to penetrate into the heating element 40 .
[0046] In addition, when the heating element 40 is running and generates heat, thereby heating the heating plate 20 and the waterproof element 30, the first annular gap 335 can leave a deformation space for the axial expansion of the second retaining ring 332 when heated, the second annular gap 336 can leave a deformation space for the axial expansion of the first retaining ring 331 when heated, the third annular gap 337 can leave a deformation space for the radial expansion of the first retaining ring 331 and the second retaining ring 332 when heated, the fourth annular gap 338 can leave a deformation space for the radial expansion of the first retaining ring 331 and the third retaining ring 333 when heated, and the fifth annular gap 339 can leave a deformation space for the radial expansion of the heating element 40 and the third retaining ring 333 when heated. In this way, the first waterproof element 301, the second waterproof element 302 and the heating element 40 can be prevented from interfering with each other after being heated, so that the heating plate 20 maintains a stable posture, and the risk of the cooking pot or food container tilting due to the change of the posture of the heating plate 20 is reduced.
[0047] Further, see Figure 2 The water retaining ring 33 also includes a water retaining flange 334, which is located at one end of the first retaining ring 331 extending into the inner ring of the second retaining ring 332 and radially protrudes relative to the outer periphery of the first retaining ring 331. In this way, the leakage path of the liquid from the outer periphery of the second retaining ring 332 to the inner periphery of the third retaining ring 333 is more tortuous and complex, and the possibility of liquid leakage and then adhering to the heating element 40 is reduced and the difficulty is increased, and the waterproof protection effect of the heating element 40 is more in place.
[0048] Furthermore, in some embodiments, the first closed loop end 31 is sealed and bonded to the surface of the stove top 10 facing away from the stove body 50 , and the end surface of the heating plate 20 facing the stove cavity 51 and the heating element 40 is sealed and bonded to the second closed loop end 32 .
[0049] The cooking stove 100 of the present invention blocks liquid from leaking along the stove top 10 into the stove hole 11 through the first closed loop end 31, blocks liquid from leaking along the heating plate 20 into the stove hole 11 through the second closed loop end 32, and seals the first closed loop end 31 and the second closed loop end 32 through the water retaining ring 33, thereby effectively preventing liquid foreign matter such as soup, cleaning liquid, etc. from leaking from the opening of the stove hole 11 and the heating plate 20 into the cooking stove 100, thereby having better waterproof ability and providing effective waterproof protection for functional components inside the cooking stove 100.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
