Some cookers, such as electric hot pots, generally include a heating assembly and a base assembly, the heating assembly being provided on the base assembly and forming a closed cavity with the base assembly, both the electric elements and the wires being located in the cavity. When the heating component works, heat can be quickly transferred to wires or electric elements, so that the wires or parts of the electric elements are overhigh in temperature, damage is easy to occur, and the service life is reduced.

In order to solve the above problems, as shown in fig. 1 to 5, the present application provides a cooking appliance capable of reducing the temperature of an assembly area of an electric element, thereby ensuring the normal service life of the cooking appliance.

As shown in fig. 1, specifically, the cooking appliance includes a base assembly and a pot body (not shown), the pot body is disposed on the base assembly, the base assembly includes a heating assembly 10, an electric device, a ring-shaped support frame 20 and a bottom shell 30, the heating assembly 10 is mounted on the support frame 20, the support frame 20 is disposed on the bottom shell 30, a first blocking rib 21 is disposed on a side of the support frame 20 facing the bottom shell 30, a second blocking rib 31 is disposed on a side of a bottom wall of the bottom shell 30 facing the support frame 20, the first blocking rib 21 and the second blocking rib 31 are partially overlapped in a vertical direction and are disposed at intervals in a horizontal direction, the first blocking rib 21 is disposed outside the second blocking rib 31, the electric device is disposed in a region near a side of the support frame 20 and the first blocking rib 21 away from the heating assembly, or the first blocking rib 21 is disposed inside the second blocking rib 31, and the electric device is disposed in a region near a side of the bottom wall of the bottom shell 30 and the second blocking rib 31 away from the heating assembly.

When the first rib 21 is located at the outer side of the second rib 31, the first rib 21, the top surface of the support frame 20 and the side wall of the bottom shell 30 enclose an assembly area 40 for accommodating an electric device, heat generated by the heating assembly 10 needs to be turned at the second rib 31 and the first rib 21 in sequence and then can enter the assembly area 40, and when the first rib 21 is located at the inner side of the second rib 31, the bottom wall of the bottom shell 30 and the side wall of the bottom shell 30 enclose the assembly area 40 for accommodating the electric device, and heat generated by the heating assembly 10 needs to be turned at the first rib 21 and the second rib 31 in sequence and then can enter the assembly area 40.

In the cooking appliance provided by the embodiment of the utility model, the first blocking rib 21 and the second blocking rib 31 are positioned between the heating assembly 10 and the electric device, and the first blocking rib 21 and the second blocking rib 31 are provided with the overlapping area in the vertical direction, so that heat generated by the heating assembly 10 cannot directly enter the assembly area 40, but can enter the assembly area 40 only after the second blocking rib 31 and the first blocking rib 21 turn, thereby prolonging the heat dissipation path a of the electric device, which is transmitted by the heat generated by the heating assembly 10, and the first blocking rib 21 and the second blocking rib 31 can isolate and absorb part of the heat, thereby reducing the heat flowing from the heating assembly 10 to the assembly area 40, reducing the temperature of the electric device, avoiding the damage caused by the temperature rise of the electric device, and ensuring the use safety of the cooking appliance and the normal service life of the cooking appliance.

The first rib 21 and the second rib 31 may be annular structures concentric with the base assembly, that is, the assembly area 40 is an annular area surrounded by the first rib 21 or the second rib 31 and the side wall of the bottom shell 30, or the first rib 21 and the second rib 31 may be provided only in an area where the electric device is mounted, that is, the assembly area 40 is an arc area surrounded by the first rib 21 or the second rib 31 and the side wall of the bottom shell 30.

As shown in FIG. 1, the distance between the first rib 21 and the second rib 31 in the horizontal direction is L, and L is equal to or greater than 5mm. Wherein L can be any value larger than or equal to 5mm, such as 5mm, 6mm, 7mm, 8mm and the like, and the too small interval between the two values is avoided, so that the temperature of the bottom shell 30 is too high.

As shown in FIG. 2, the overlapping length of the first blocking rib 21 and the second blocking rib 31 in the vertical direction is H1, and H1 is more than or equal to 10mm. Wherein H1 may be any value of 10mm, 11mm, 12mm, 13mm, etc. or more than or equal to 10mm. It will be appreciated that the greater the overlap length H1 of the first rib 21 and the second rib 31 in the vertical direction, the longer the heat dissipation path a of the heat generated by the heating assembly 10 is transferred to the assembly area 40, the less the heat is transferred to the assembly area 40, and the lower the temperature in the assembly area 40 is, so as to ensure that the temperature in the assembly area 40 meets the operating temperature of the electric device.

As shown in fig. 2, the bottom surface of the heating assembly 10 is at a lower level than the top surface of the second rib 31. Namely, the height difference H2 obtained by subtracting the height of the bottom surface of the heating assembly 10 from the height of the top surface of the second rib 31 satisfies that H2 is not less than 0mm. Therefore, the heat radiated downwards by the heating assembly 10 cannot directly enter the gap between the first blocking rib 21 and the second blocking rib 31, but needs to enter the gap between the first blocking rib 21 and the second blocking rib 31 after the end, far away from the bottom shell 30, of the second blocking rib 31 turns, and needs to enter the assembly area 40 after the end, far away from the support frame 20, of the first blocking rib 21 turns, so that the heat radiation path a, where the heat generated by the heating assembly 10 is transmitted to the assembly area 40, of the heating assembly can be prolonged, and the temperature in the assembly area 40 is further reduced.

As shown in fig. 1, 4 and 5, in one embodiment, the bottom chassis 30 includes a housing 32 and a bottom plate 33 connected to the housing 32. The bottom case 30 is provided in a split structure to facilitate production and processing. In addition, the housing 32 and the bottom plate 33 may be made of different materials, and since the heat of the heating element 10 is radiated downwards, the temperature at the bottom plate 33 is generally high, so that the bottom plate 33 needs to be made of a material resistant to high temperature. The high temperature resistant material is generally high in cost and the temperature of the housing 32 is low, so the housing 32 may be made of a material with relatively weak heat resistance.

Wherein, the bottom plate 33 can be made of one material of PET, PBT or PA, and the PET, PBT and PA materials have better heat resistance so as to ensure that the bottom plate 33 is not damaged in a high-temperature environment for a long time. The shell 32 can be made of a PP material, which has high strength and low cost, so that the overall strength of the bottom shell 30 can be ensured, and the production cost can be reduced.

Of course, in other embodiments, the bottom case 30 may be an integral structure, as long as the strength and heat resistance of the entire bottom case 30 can be ensured, and the embodiment of the present utility model is not particularly limited herein.

The buckle has a simple structure, is convenient for assembling the shell 32 and the bottom plate 33, is convenient for disassembling and maintaining other elements in the bottom shell 30, and can also ensure the stability and reliability of the connection of the shell 32 and the bottom plate 33 in an assembling state, thereby ensuring the use safety.

As shown in fig. 1, 4 and 5, specifically, the housing 32 includes a side wall 321 and a hollow bottom wall 322, the bottom plate 33 is mounted on the bottom wall 322, one of the bottom plate 33 and the bottom wall 322 is provided with a latch 34, and the other is provided with a latch 35 engaged with the latch 34. The outer fringe of support frame 20 is connected with the top of lateral wall portion 321, and assembly district 40 is enclosed by first fender muscle 21, the top surface of support frame 20 and lateral wall portion 321. The bottom wall portion 322 of the housing 32 can be reduced in size of the bottom plate 33 as long as the bottom plate 33 can cover the bottom surface of the heating assembly 10, so that the production cost can be further reduced. Moreover, the assembly of the bottom plate 33 and the shell 32 can be completed only by clamping and matching the buckle 34 with the clamping block 35, the assembly process is simple and convenient, and the operation of a user is convenient.

In the illustrated embodiment, the second rib 31 is provided on the bottom plate 33, the catch 34 is provided on the outer peripheral wall of the second rib 31, and the catch 35 is provided on the bottom wall portion 322. Therefore, the heat generated by the heating assembly 10 needs to pass through the end of the second rib 31 away from the bottom plate 33 before contacting with the housing 32, so that the temperature of the housing 32 can be reduced, and the damage of the housing 32 is avoided. Alternatively, the latch 35 may be provided on the outer peripheral wall of the second rib 31, and the catch 34 may be provided on the bottom wall 322.

In another embodiment, the second rib 31 may be provided at the innermost side of the bottom wall portion 322, and one of the clip 34 and the clip 35 may be provided on the inner peripheral wall of the second rib 31, and the other may be provided on the bottom plate 33.

The number of the buckles 34 may be two, three, four or more, the plurality of buckles 34 are arranged at intervals along the periphery of the second blocking rib 31, the number of the clamping blocks 35 is also a plurality of, and the clamping blocks 34 are arranged in one-to-one correspondence to ensure the stability and reliability of the connection of the housing 32 and the bottom plate 33 in the assembled state.

Of course, in other embodiments, the housing 32 and the bottom plate 33 may be connected by fasteners such as screws or bolts, so long as the stability and reliability of the connection of the housing 32 and the bottom plate 33 in the assembled state can be ensured, and the embodiment of the present utility model is not particularly limited herein.

As shown in fig. 1, the heating assembly 10 comprises a heating plate 11, a heating tube 13 and an electric connection terminal 14, wherein the heating tube 13 is fixedly arranged on the heating plate 11, the heating tube 13 comprises a tube body segment 131 and an extraction segment 132, the tube body segment 131 is embedded in the heating plate 11, the extraction segment 132 protrudes out of the heating plate 11, the electric connection terminal 14 is fixedly arranged on the extraction segment 132, and the maximum distance H3 between the electric connection terminal 14 and the surface of the heating plate 11 in the vertical direction is less than or equal to 30mm. The heating pipe 13 is electrically connected to other elements in the bottom case 30 through the power connection terminal 14, and heats the pot placed on the heating plate 11 through the heating plate 11. Although the reduction of the distance between the electrical connection terminal 14 and the surface of the heating plate 11 in the height direction can reduce the overall thickness of the heating assembly 10, so as to facilitate the storage and dish clamping of the user, since the lead-out section 132 and the electrical connection terminal 14 are both protruded from the bottom of the heating plate 11, when the distance H3 between the electrical connection terminal 14 and the surface of the heating plate 11 is reduced, the bottom space height of the heating plate 11 is correspondingly reduced, and the heat dissipation rate is also reduced. In the present application, the heat at the bottom of the heating plate 11 can radiate from the radiating path a formed by the first blocking rib 21 and the second blocking rib 31, so as to improve a certain radiating rate and avoid the cable or the electric device in the bottom shell 30 from being in a high-temperature environment for a long time due to the excessively low radiating rate.

As shown in fig. 1, the heating assembly 10 further includes a reflecting cover 12, and the reflecting cover 12 is disposed below the heat generating plate 11.
