Description

Technical Field

[0001] The present application relates to the technical field of stoves or ranges heated by electric energy, and in particular to a flat or concave dual-purpose stove. Background Art

[0002] When it comes to kitchen appliances, induction cookers and ceramic cooktops are both common heating devices. Ceramic cooktops can heat any heat-resistant cookware, regardless of the material, including iron, aluminum, tile, and ceramic. However, ceramic cooktops currently available typically heat the cookware on a flat surface, making them suitable only for flat-bottomed pans, limiting their application.

[0003] The flat ceramic cooktops on the market solve the problem of pot material. Although there are concave ceramic cooktops and concave induction cooktops, the frying pans cannot be placed stably. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a stove suitable for flat-bottomed and concave-bottomed cookware, and the technical solutions adopted include:

[0005] A flat and concave dual-purpose stove comprises an outer shell and an electric heater arranged in the outer shell. A pot rack is arranged on the outer periphery of the electric heater at the upper end of the outer shell. The inner wall of the pot rack is provided with a plurality of ribs spaced along the circumference thereof.

[0006] A preferred embodiment of the present application: the horizontal height of the protruding rib is lower than the horizontal height of the upper end of the pot rack.

[0007] A preferred embodiment of the present application: the inner wall of the pot rack is arc-shaped.

[0008] A preferred embodiment of the present application: the pot rack is detachably mounted on the shell.

[0009] A preferred embodiment of the present application: the outer shell includes a shell with a hollow interior, an opening is provided at the upper end of the shell, the shell is bent upward at the opening to form a bent portion, the pot rack is U-shaped, the shape of the bent portion is consistent with the shape of the pot rack, and the pot rack is installed downward on the bent portion.

[0010] A preferred embodiment of the present application: the electric heater includes a heating component and a panel arranged at the upper end of the heating component, the inner wall of the pot rack extends downward to form an extension portion, and the extension portion abuts against the upper end of the panel.

[0011] A preferred embodiment of the present application further comprises a limiting piece, both ends of which are respectively connected to the heating component and the housing, and the limiting piece is used to limit the panel at the upper end of the heating component.

[0012] A preferred embodiment of the present application: both ends of the limiting piece are detachably connected to the heating component and the outer shell respectively.

[0013] A preferred embodiment of the present application: a plurality of threaded columns are installed at the lower end of the pot rack, and a through hole matching the threaded column is provided on the bent portion. After the threaded column passes through the through hole, it is installed on the bent portion through a nut that matches its thread.

[0014] Beneficial effects of the utility model:

[0015] 1. The pot stand protrudes from the upper end of the shell, and a certain distance is left between the protruding ribs and the upper end of the electric heater. Space is left between the protruding ribs and the electric heater for recessed-bottom cookware to extend into. The bottom of a frying pan can be placed directly on the electric heater or on the multiple protruding ribs. The recessed-bottom cookware can be placed on the pot stand and supported on the outer wall of the cookware by the multiple protruding ribs. The bottom of the recessed-bottom cookware extends into the pot stand, making the stove suitable for heating both frying pans and recessed-bottom pans. The pot stand not only makes the electric ceramic stove not picky about the material of the cookware, but also solves the problem of being picky about the shape of the cookware.

[0016] 2. When the concave-bottom cookware is supported on the outer wall of the cookware by a plurality of the protruding ribs, a certain gap is left between the bottom wall of the concave-bottom cookware and the inner wall of the pot rack. On the one hand, when the moisture on the bottom wall of the cookware evaporates due to heat to generate water vapor, the water vapor can escape through the gap between the bottom of the pot and the inner wall of the pot rack, thereby avoiding the safety hazard caused by the close contact between the bottom of the pot and the inner wall of the pot rack and the water vapor ejecting from between the bottom of the pot and the inner wall of the pot rack; on the other hand, the heat generated by the electric heater can be radiated from between the bottom wall of the pot and the inner wall of the pot rack to the upper part of the cookware. The pot rack can effectively surround the heat in the bottom of the pot, so that the heat does not dissipate, thereby significantly improving the thermal efficiency of the stove.

[0024] Reference Figure 1-2 , an embodiment of the present application is proposed, the flat and concave dual-purpose stove described in this embodiment is suitable for a stove, the stove includes an outer shell 20 and an electric heater 30 arranged in the outer shell 20, the upper end of the outer shell 20 is provided with a pot rack 10 on the outer periphery of the electric heater 30, and the inner wall of the pot rack 10 is provided with a plurality of protruding ribs 40 distributed along its circumference at intervals.

[0025] The pot support 10 protrudes from the upper end of the shell 20, and a certain distance is left between the protruding ribs 40 and the upper end of the electric heater 30. There is space between the protruding ribs 40 and the electric heater 30 for the concave-bottom cookware to extend into. The bottom of a frying pan can be placed directly on the electric heater 30 or multiple protruding ribs 40; the concave-bottom cookware can be placed on the pot support 10 and supported on the outer wall of the pot by multiple protruding ribs 40, and the bottom of the concave-bottom cookware extends into the pot support 10, so that the stove is suitable for heating both frying pans and concave-bottom pans.

[0026] When the concave-bottom cookware is supported on the outer wall of the cookware by a plurality of the protruding ribs 40, a certain gap is left between the bottom wall of the concave-bottom cookware and the inner wall of the pot rack 10. On the one hand, when the moisture on the bottom wall of the cookware evaporates due to heat to generate water vapor, the water vapor can escape through the gap between the bottom of the cookware and the inner wall of the pot rack 10, thereby avoiding the safety hazard caused by the close contact between the bottom of the cookware and the inner wall of the pot rack 10, which may cause water vapor to spray out from between the bottom of the cookware and the inner wall of the pot rack 10. On the other hand, the heat generated by the electric heater 30 can be radiated from between the bottom wall of the cookware and the inner wall of the pot rack 10 to the upper part of the cookware, which is beneficial to improving the thermal efficiency of the stove.

[0027] In the present application, the level of the rib 40 is lower than the level of the upper end of the pot rack 10 .

[0028] The inner wall of the pot rack 10 is curved and adapted to the outer wall shape of the concave bottom pot, which reduces the gap between the inner wall of the pot rack 10 and the outer wall of the pot, and reduces the space between the pot rack 10 and the pot, thereby facilitating an increase in the amount of heat radiation from the stove to the pot.

[0029] In this application, the pot stand 10 is detachably mounted on the housing 20. For ceramic or induction cooktops with openings 22 of the same size, the pot stand 10 can be directly installed onto existing ceramic or induction cooktops without requiring additional molds, facilitating assembly. In another embodiment, the pot stand 10 and the housing can be integrally formed.

[0030] Specifically, the outer shell 20 includes a shell body 21 with a hollow interior, an opening 22 is provided at the upper end of the shell body 21, and the shell body 21 is bent upward at the opening 22 to form a bending portion 23. The cross-section of the pot rack 10 is U-shaped, and the shape of the bending portion 23 is consistent with the shape of the pot rack 10. The pot rack 10 is installed downward on the bending portion 23.

[0031] In this embodiment, the upper opening 22 of the housing 20 is bent upward to form a bent portion 23. The pot stand 10 is mounted on the bent portion 23, which facilitates assembly and helps improve the supporting strength of the pot stand 10 for the pot. The pot stand 10 is suitable for retrofitting all electric ceramic stoves or recessed induction cookers with the bent portion 23.

[0032] The bending portion 23 is a conventional design of stoves in this field. In this embodiment, the pot rack 10 is detachably mounted on the bending portion 23 on the shell 12. The shape design of the pot rack 10 allows the pot rack 10 to be additionally installed on the stove shell having the bending portion 23.

[0033] The electric heater 30 includes a heating assembly 31 and a panel 32 disposed on the upper end of the heating assembly 31. The inner wall of the pot rack 10 extends downward to form an extension portion 11, and the extension portion 11 abuts against the upper end of the panel 32. As shown in the accompanying drawings, the extension portion 11 forms an annular platform, and the annular platform abuts against the upper end of the panel 32.

[0034] The panel 32 is a glass panel, and a high-temperature resistant sealant is coated between the panel 32 and the annular table. The annular table is pressed against the upper end of the panel 32 to ensure that the panel 32 stably covers the upper end of the heating component 31, thereby preventing the panel 32 from falling off when the side-standing stove is cleaned, thereby exposing the heating part of the heating component 31 and causing leakage.

[0035] A plurality of threaded columns 12 are installed at the lower end of the pot rack 10. The bent portion is provided with through holes matching the threaded columns. The threaded columns pass through the through holes and are installed on the bent portion 23 via nuts that are threadably matched with the threads.

[0036] Furthermore, a limiting plate 50 is included, the two ends of which are respectively connected to the outer shell 20 and the heating component 31, and the limiting plate is used to limit the panel 32 at the upper end of the heating component 31, so as to prevent the panel 32 from moving on the heating component 31 after the sealant fails, causing the heating part of the heating component 31 to be exposed and leaking. Specifically, the limiting plate 50 is detachably connected to the outer shell 20 and the panel 32, which is convenient for installation. In this embodiment, one end of the limiting plate 50 is provided with a waist-round hole 1, and the threaded column passes through the through hole and the waist-round hole 1, and the limiting plate 50 is locked to the outer shell 20 by a nut matched therewith. The other end of the limiting plate 50 is also provided with a waist-round hole 2, and the tail of the bolt at the other end of the limiting plate 50 passes through the waist-round hole 2 and is tightened on the heating component 31 and the limiting plate 50 is locked to the heating component 31 by the head of the bolt.

[0037] There are multiple limiting pieces 50 , which are spaced apart along the circumference of the opening in the housing 10 to stably limit the panel 32 .

[0038] Of course, the present invention is not limited to the above-mentioned embodiments. Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications and substitutions are all included in the scope defined by the claims of this application.
