Description

Technical Field

[0001] This invention belongs to the field of induction cookers, specifically relating to an induction cooker heating plate with moisture-proof function. Background Technology

[0002] Existing induction cookers typically have ventilation openings at the bottom of the casing, and heat is dissipated by an internal fan. Since the kitchen environment is humid, the fan draws moisture into the induction cooker, resulting in excessive humidity inside. Furthermore, the heating element of existing induction cookers does not have a moisture-proof function, making it susceptible to moisture damage. Summary of the Invention

[0003] To overcome the drawback that the fan draws moisture into the induction cooker, causing the heating element inside to become damp and damaged, this invention provides an induction cooker heating element with moisture-proof function.

[0004] The technical solution of the present invention is as follows: an induction cooker heating plate with moisture-proof function, comprising an upper shell and a bottom plate; the bottom plate is fixedly connected to the upper shell; the upper shell has several air vents on its left side; it also includes a waterproof frame, a water-absorbing block, and a heat dissipation assembly; the heating plate is connected to the bottom plate; the bottom plate has an air inlet, and a heat dissipation assembly for heat dissipation is connected to the bottom plate, the heat dissipation assembly corresponding to the air inlet; the waterproof frame is fixedly connected to the bottom plate, and both the waterproof frame and the heat dissipation assembly are located below the heating plate; a water-absorbing block is detachably connected inside the waterproof frame.

[0005] Furthermore, the heat dissipation assembly includes mounting rods and a fan; several mounting rods are connected to the base plate; and a fan is connected to all the mounting rods.

[0006] Furthermore, it also includes an electric heating plate; the electric heating plate is connected to the waterproof frame; and several through slots are opened on the electric heating plate.

[0007] Furthermore, it also includes an arc-shaped frame; an arc-shaped frame is fixed to the heating plate, the arc-shaped frame matches the shape of the fan frame, and the arc-shaped frame fits snugly against the fan frame.

[0008] Furthermore, an electric heating wire is installed inside the waterproof frame.

[0009] Furthermore, it also includes protective components. A protective component is connected to the underside of the base plate, directly opposite the air inlet of the upper shell. Another protective component is connected to the left side of the upper shell, directly opposite the air outlet of the upper shell. The protective component connected to the underside of the base plate consists of a protective plate, elastic clips, and a protective net. Several elastic clips are snapped onto the underside of the base plate. All elastic clips are connected to a protective plate, which contacts the absorbent block. Several through holes are opened on the protective plate, and a protective net is installed in each through hole. All protective nets are directly opposite the air inlet on the underside of the base plate.

[0010] Furthermore, it also includes an extrusion plate, a tensioning frame, and elastic elements; several elastic elements are fixedly connected to the lower side of the heating plate; an extrusion plate is fixedly connected to the lower side of all elastic elements; several ventilation holes are opened on the extrusion plate; the tensioning frame passes through the upper shell; the tensioning frame is slidably connected to the upper shell.

[0011] Furthermore, it also includes hollow rollers; several hollow rollers are installed in the through holes of the protective plate of the protective component on the left side of the upper shell; the protective plate has slots that match the rotating part of the hollow rollers; the outer surface of the hollow rollers is composed of several reinforcing ribs and several breathable fabrics; the inside of the hollow rollers is filled with moisture-absorbing particles.

[0012] Furthermore, the absorbent block is connected to several waterproof discs that are directly opposite the ventilation holes, and the waterproof discs are the same size as the ventilation holes.

[0013] Furthermore, the absorbent block has several liquid guiding grooves.

[0014] The beneficial effects are: When this invention is used, it achieves the absorption of water by the water-absorbing block and the protection of the water-absorbing block by the waterproof frame, so as to prevent the water absorbed by the water-absorbing block from overflowing into the induction cooker, thereby preventing water from entering the induction cooker through the air inlet and preventing the heating plate from getting damp and damaged.

[0015] The heat from the heating plate is used to dry the water-absorbing block, which speeds up the drying process. The air blown out by the fan blows the water-absorbing block through the through groove, and then blows the moisture evaporated from the dried water-absorbing block to the outside of the induction cooker through the air inlet on the bottom plate, so as to prevent the moisture evaporated from the dried water-absorbing block from entering the induction cooker and causing the heating plate to become damp and damaged.

[0016] By squeezing the absorbent plates of the absorbent block with an extrusion plate, the water inside the absorbent block is quickly squeezed out, thereby rapidly reducing the moisture content of the absorbent block, reducing the time required for the electric heating plate to dry the absorbent block, and saving energy.

Detailed Implementation

[0029] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0030] Example 1

[0031] A moisture-proof heating element for induction cookers, such as Figure 1-7 As shown, it includes an upper shell 2 and a bottom plate 3; the bottom plate 3 is bolted to the upper shell 2; several air vents are opened on the upper left side of the upper shell 2;

[0032] It also includes a waterproof frame 101, a water-absorbing block 102, and a heat dissipation component; a heating plate 001 is connected to the base plate 3; an air inlet is opened on the base plate 3, and a heat dissipation component is connected to the base plate 3, with the heat dissipation component corresponding to the air inlet; a waterproof frame 101 is fixedly connected to the base plate 3, and both the waterproof frame 101 and the heat dissipation component are located below the heating plate 001; a water-absorbing block 102 is detachably connected inside the waterproof frame 101.

[0033] The heat dissipation assembly includes a mounting rod 103 and a fan 104; the base plate 3 is connected to four mounting rods 103; and the fan 104 is connected to all the mounting rods 103.

[0034] In use, this device is installed inside the induction cooker as a heating module. The air outlet on the upper shell 2 serves as the air outlet of the induction cooker, and the air inlet on the bottom plate 3 serves as the air inlet. When the induction cooker is in use, the fan 104 is turned on. The fan 104 draws cold air from the outside into the induction cooker through the air inlet on the lower side of the bottom plate 3, allowing the hot air inside the induction cooker to be discharged through the air outlet on the upper shell 2, thereby dissipating heat from the inside of the induction cooker. Since the kitchen is usually humid, the fan 104 drawing outside air into the induction cooker can also easily lead to excessive humidity inside the induction cooker, causing the heating plate 001 inside the induction cooker to become damp and damaged. Therefore, when the fan 104 draws outside air into the induction cooker through the air inlet, the outside air first passes through the water absorption block 102, which absorbs the moisture in the outside air, preventing excessive humidity inside the induction cooker from causing the heating plate 001 to become damp and damaged.

[0035] When using an induction cooker in the kitchen, it's inevitable that water will be spilled or splashed onto the kitchen countertop, causing water to accumulate. This water can easily enter the induction cooker through the air inlet on the underside of the base plate 3, potentially damaging the heating plate 001. When water enters the induction cooker through the air inlet, it first comes into contact with the water-absorbing block 102, which absorbs the water. The waterproof frame 101 protects the water-absorbing block 102, preventing the absorbed water from overflowing into the induction cooker. This, in turn, prevents water from entering the induction cooker through the air inlet, thus preventing the heating plate 001 from becoming damp and damaged.

[0036] Example 2

[0037] Based on Example 1, such as Figure 1-9 As shown,

[0038] It also includes an electric heating plate 203; the electric heating plate 203 is connected to the waterproof frame 101; and the electric heating plate 203 has several through slots 002.

[0039] It also includes an arc frame 204; the arc frame 204 is fixed on the heating plate 203, the arc frame 204 matches the shape of the fan 104 frame, and the arc frame 204 fits into the fan 104 frame, and the arc frame 204 guides and limits the air blown out by the fan 104.

[0040] A heating wire is installed inside the waterproof frame 101 to heat and dry the water-absorbing block 102 inside the waterproof frame 101.

[0041] After prolonged use, the water-absorbing block 102 inevitably reaches saturation. To prevent the water-absorbing block 102 from losing its water-absorbing effect, it needs to be dried. When drying the water-absorbing block 102, the heating plate 203 and the heating wire in the waterproof frame 101 are activated to dry the water-absorbing block 102, ensuring its water-absorbing effect. At the same time, the fan 104 is reversed to blow air out through the air inlet of the bottom plate 3, thereby using the heat of the heating plate 001 to dry the water-absorbing block 102 and speed up the drying process. The air blown out by the fan 104 is blown towards the water-absorbing block 102 through the through groove 002, thereby blowing the moisture evaporated from the drying of the water-absorbing block 102 to the outside of the induction cooker through the air inlet of the bottom plate 3, preventing the moisture evaporated from the drying of the water-absorbing block 102 from entering the induction cooker and causing the heating plate 001 to become damp and damaged.

[0042] Example 3

[0043] Based on Example 2, such as Figure 8-11 As shown,

[0044] It also includes protective components. The lower side of the base plate 3 is connected to a protective component that faces the air inlet of the upper shell 2. The upper left side of the upper shell 2 is connected to another protective component that faces the air outlet of the upper shell 2. The protective component connected to the lower side of the base plate 3 consists of a protective plate 301, elastic buckles 302, and a protective net 303. Four elastic buckles 302 are snapped onto the lower side of the base plate 3. All elastic buckles 302 are connected to the protective plate 301, which is in contact with the water-absorbing block 102. The protective plate 301 has several through holes, and a protective net 303 is installed in each through hole. The protective net 303 in the protective plate 301 intercepts cockroaches in the kitchen, preventing cockroaches from entering the induction cooker and causing malfunctions. All protective nets 303 are directly opposite the air inlet on the lower side of the base plate 3.

[0045] It also includes an extrusion plate 401, a tensioning frame 402, and elastic elements 403; four elastic elements 403 are fixedly connected to the lower side of the heating plate 203; the extrusion plate 401 is fixedly connected to the lower side of all elastic elements 403; several ventilation holes 005 are opened on the extrusion plate 401; the tensioning frame 402 penetrates the upper shell 2; the tensioning frame 402 is slidably connected to the upper shell 2.

[0046] It also includes hollow rollers 501; several hollow rollers 501 are provided in the through holes of the protective plate 301 of the protective component on the upper left side of the upper shell 2; the protective plate 301 has a slot that matches the rotating part of the hollow rollers 501; the outer surface of the hollow rollers 501 is composed of several reinforcing ribs 501a and several breathable cloths 501b; the hollow rollers 501 are filled with moisture-absorbing particles.

[0047] The water-absorbing block 102 is connected to several waterproof discs 006 that are directly opposite to the ventilation holes 005. The waterproof discs 006 are the same size as the ventilation holes 005. The waterproof discs 006 seal the ventilation holes 005 to prevent water from overflowing through the ventilation holes 005 when the extrusion plate 401 extrudes the water-absorbing block 102.

[0048] The absorbent block 102 has several liquid guiding grooves 004. When the absorbent block 102 suddenly comes into contact with a large amount of liquid, the liquid is quickly guided to the middle of the absorbent plate through the liquid guiding grooves 004, thereby improving the instantaneous water absorption effect of the absorbent block 102.

[0049] When the fan 104 is reversed to dry the water-absorbing block 102, outside air enters the induction cooker directly through the air outlet, which can easily bring in external moisture and cause the heating plate 001 to become damp and damaged. Therefore, the moisture-absorbing particles in the hollow roller 501 absorb the moisture. When the induction cooker is in normal use, the hot air inside the induction cooker is discharged through the air outlet and dries the moisture-absorbing particles in the hollow roller 501, thus extending the effective time of the moisture-absorbing particles in the hollow roller 501.

[0050] When it is necessary to clean the protective net 303 or replace the hollow roller 501, press the elastic buckle 302 on the protective plate 301 and remove the protective plate 301 from the lower side of the bottom plate 3 or the left side of the upper shell 2. Then the protective net 303 can be cleaned and the hollow roller 501 can be removed from the protective plate 301 for replacement. This will prevent the protective net 303 from accumulating dirt and clogging after long-term use, and prevent the moisture-absorbing particles in the hollow roller 501 from losing their moisture-absorbing effect after long-term use.

[0051] After the absorbent block 102 absorbs a large amount of water, directly drying it through the heating plate 203 would take a long time and waste energy. At this point, the user holds the induction cooker and pulls the stretching frame 402. The stretching frame 402 moves the extrusion plate 401 towards the absorbent block 102, stretching the elastic element 403 and causing the extrusion plate 401 to fit against the absorbent block 102. The waterproof disc 006 on the absorbent block 102 then engages with the vent hole 005, thus closing the vent hole 005. As the stretching frame 402 continues to be pulled, the extrusion plate 401 squeezes the water-absorbing block 102. The water inside the water-absorbing block 102 is squeezed out by the extrusion plate 401 and flows into the air inlet of the bottom plate 3, and then flows out through the air inlet. Then the stretching frame 402 is released, and the extrusion plate 401 is reset by the elastic force of the elastic element 403, which in turn drives the stretching frame 402 to reset, thereby quickly squeezing out the water inside the water-absorbing block 102, quickly reducing the moisture content of the water-absorbing block 102, reducing the time required for the heating plate 203 to dry the water-absorbing block 102, and saving energy.

[0052] When the fan 104 draws cold air from the outside into the induction cooker through the air inlet on the lower side of the base plate 3, it inevitably draws in a small amount of oil fumes. Therefore, the water absorption block 102 intercepts and absorbs the oil fumes. After long-term use, oil stains will accumulate on the lower side of the water absorption block 102. In order to avoid affecting the performance of the water absorption block 102, it is necessary to perform deep cleaning or replace it regularly. When performing deep cleaning or replacement, remove the protective plate 301 on the lower side of the base plate 3 and remove the water absorption block 102 from the waterproof frame 101 through the air inlet on the lower side of the base plate 3 for deep cleaning or replacement with a new water absorption block 102.
