Abstract
The utility model relates to an electric heating pan and belongs to the field of cooker. The electric heating pan comprises a pan body and an electric heating pipe and is characterized in that the electric heating pipe comprises an outer metal pipe, the cross section of the outer metal pipe is U-shaped, the top of the outer metal pipe is a plane, and an electric heating wire is arranged in the outer metal pipe. Insulating media is filled between the electric heating wire and the inner wall of the outer metal pipe, two ends of the electric heating wire are provided with connecting terminals, and a metal plate is arranged between the outer metal pipe and the bottom of the pan body. Compared with existing electric heating pans, the cross section of the outer metal pipe adopted by the electric heating pan is U-shaped, the top of the outer metal pipe is a plane, and the metal plate is further arranged between the outer metal pipe and the bottom of the pan body, thereby enabling good contact between the pan body and the metal plate and between the metal plate and the outer metal pipe, being high in heat transfer efficiency and small in power consumption, and shortening heating time.
Description
Technical field
The utility model relates to a kind of electric food warmer, belongs to the cooker field.
Background technology
At present, the electrothermal tube that existing electric food warmer adopts is typically provided with 1 metal tube, in metal tube, is provided with heating wire, and fills magnesia powder, because metal tube is that point contacts with bottom of pot body, has phenomenons such as heat transfer efficiency is low, thermal waste is big.
The utility model content
According to above deficiency of the prior art, the technical problem that the utility model will solve is: provide a kind of heat time heating time short, heat transfer efficiency is high, the electric food warmer that power consumption is little.
The described electric food warmer of the utility model comprises pot body and electrothermal tube, it is characterized in that: electrothermal tube comprises outer metal tube; Outer metal tube cross section takes the shape of the letter U; The top is the plane, is provided with heating wire in the outer metal tube, is filled with dielectric between heating wire and the outer inner wall of metal tube; The heating wire two ends are provided with binding post, are provided with metallic plate between metal tube and the bottom of pot body outside.
Because outer metal tube cross section takes the shape of the letter U, and the top is the plane, strengthened the contact area of outer metal tube and metallic plate.In use, the heat transferred metallic plate that outer metal tube can produce heating wire fast, metallic plate are again with the heat transferred bottom of pot body, and in whole heating process, heat time heating time is short, and heat transfer efficiency is high, and power consumption is little.
Wherein, the preferable alloy plate adopts circular aluminium sheet, and its heat-transfer effect is obvious.
Use the utility model for ease, the pot body is provided with handle.
Wherein, said electrothermal tube outer periphery is equipped with protective cover, and protective cover is fixed on pot body.Protective cover safety and reliability in use is set.
Compared with prior art, the utlity model has following beneficial effect:
Compare with existing electric food warmer; Because the outer metal tube cross section that the utility model adopts takes the shape of the letter U, and the top is the plane, is provided with metallic plate between metal tube and the bottom of pot body outside again; Make and all have excellent contact between pot body and metallic plate, metallic plate and the outer metal tube; Heat transfer efficiency is high, has shortened heat time heating time, and power consumption is little.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is an A-A cross-sectional view among Fig. 1;
Among the figure: 1, handle 2, pot body 3, heating wire 4, dielectric 5, outer metal tube 6, metallic plate 7, protective cover 8, binding post.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described:
Like Fig. 1, shown in Figure 2, the described electric food warmer of the utility model comprises pot body 2 and electrothermal tube; Electrothermal tube comprises outer metal tube 5, and outer metal tube 5 cross sections take the shape of the letter U, and the top is the plane; Be provided with heating wire 3 in the outer metal tube 5; Be filled with dielectric 4 between heating wire 3 and outer metal tube 5 inwalls, heating wire 3 two ends are provided with binding post 8, are provided with metallic plate 6 between metal tube 5 and pot body 2 bottoms outside.
In the present embodiment, metallic plate 6 adopts circular aluminium sheet, and pot body 2 is provided with handle 1, and the electrothermal tube outer periphery is equipped with protective cover 7, and protective cover 7 is fixed on pot body 2.
In use; Give heating wire 3 energisings, owing to outer metal tube 5 cross sections take the shape of the letter U, and the top is the plane; Strengthened the contact area of outer metal tube 5 and metallic plate 6; The heat transferred metallic plate 6 that outer metal tube 5 can produce heating wire 3 fast, metallic plate 6 is again with heat transferred pot body 2 bottoms, thus completion is to the purpose of pot body 2 heating.
