Abstract

A kind of novel electric cooker heating inner liner, including liner pot body and bottom-heated disk, the bottom centre of the liner pot body is provided with the boss to liner pot nside protrusion, the bottom-heated disk is fixed at the bottom surface of liner pot body, the bottom-heated disk center is additionally provided with boss heating dish corresponding with projection shape, and the boss heating dish is fixed in boss.The utility model electric rice cooker heated liner is by being arranged the bottom centre of liner pot body generally to the boss of liner pot nside protrusion, bottom-heated disk is provided with boss heating dish corresponding with projection shape, so that the food heated is during heating, the temperature difference of each section reduces, thermal gradient is small, it is with obvious effects to by the mouthfeel promotion of heating food entirety, especially heating rice；Because heat gradient is small in heating process, homogeneous heating shortens whole heating time, moreover, heating is outside the mediad of heating object, thermal losses is small, saves energy.

Description

Novel electric cooker heating inner liner

Technical field

The utility model is related to cooker product scope, espespecially a kind of novel electric cooker heating inner liner.

Background technology

The heating inner liner of existing electric cooker, a bottom generally plane or the cambered surface for having certain radian, Fig. 1 are shown One traditional bottom is the sectional view of the electric cooker inner container of plane.

When being heated to the food in liner, generally there are two types of modes for the prior art, and one is bottom-heateds, another Kind is exactly three-dimensional heating.Fig. 2 show the schematic diagram of bottom-heated, and Fig. 3 is shown increases adding for side around liner The schematic diagram of the three-dimensional heating of hot plate.

As shown in Fig. 2, in the bottom of liner there are one heat-generating disc similar with liner floor space, when work, heat-generating disc production Raw heat is transmitted to liner at the bottom by heat transfer, then is transmitted to the internal bottom by heating food.Heat passes through again later It conducts and convection current to entirety.Because it is a slow physical process that heat, which is transmitted, in heating when starting to very long one section In, or even until the food entirely heated is all ripe, in the inside of food, the arrow direction of the heat signal of such as heating is all deposited In thermal gradient, different according to the different materials by heating food, this thermal gradient size will be different.With the rice of heating For, as shown in Figure 2, the bottom centre B point mosts of the time are 5~10 degrees Celsius high compared with the temperature of top A points.And this temperature Difference will have a direct impact on the mouthfeel of rice and ripe degree when stewing rice.

As shown in figure 3, to increase the sectional view of a circle heating dish around liner.Heat is mainly when heated for it It is transmitted by the center top of bottom and four circumferential heating objects.During heating, when the temperature major part of central upper portion A points Between because thermal gradient presence, the temperature compared with bottom centre B points and side C points is all low.And because the transmission of heat is by structure and sky Between influence be not only that inside transmission, many situations have outside transmission, so to heat exist be lost.

Illustrated by those above, it may be seen that traditional liner heating has following two.

1. it is low by the temperature of the closer heating dish of the central temperature of heating food, there is heat for a long time during heating Gradient, the whole time for heating food are longer.

2. heating is all to heat from outside to inside, and heat there are many loss in conductive process, and the efficiency of heating surface is not high.

Invention content

It is had the advantages of simple structure and easy realization to solve the above problems, the utility model provides one kind, it is with obvious effects, it is suitble to promote Novel electric cooker heating inner liner.

To achieve the above object, the technical solution adopted in the utility model is：

A kind of novel electric cooker heating inner liner, including liner pot body and bottom-heated disk, in the bottom of the liner pot body The heart is provided with the boss to liner pot nside protrusion, and the bottom-heated disk is fixed at the bottom surface of liner pot body, institute It states bottom-heated disk center and is additionally provided with boss heating dish corresponding with projection shape, the boss heating dish is fixed at convex In platform.

Specifically, it is that truncated cone-shaped or other regular polygon platforms are either spherical at the top of the boss.

Specifically, further include side heat disk, the side heat disk is socketed in the side surface of liner pot body.

The beneficial effects of the utility model are：

(1) the utility model electric rice cooker heated liner is by being arranged the bottom centre of liner pot body generally to liner pot nside The boss of protrusion, bottom-heated disk are provided with boss heating dish corresponding with projection shape so that the food heated is heating In the process, the temperature difference of each section reduces, and thermal gradient is small, to by the mouthfeel promotion of heating food entirety, especially heating rice, It is with obvious effects.

(2) because heating process in heat gradient it is small, homogeneous heating shortens whole heating time, moreover, heating be from Outside the mediad of heating object, thermal losses is small, saves energy.

Specific implementation mode

Please refer to Fig. 4-5, a kind of novel electric cooker heating inner liner of the utility model, including liner pot body 1 and bottom-heated Disk 2, the bottom centre of the liner pot body 1 are provided with the boss 3 to 1 internal protrusion of liner pot body, and the bottom-heated disk 2 is solid The fixed bottom surface being arranged in liner pot body 1,2 center of bottom-heated disk is additionally provided with boss corresponding with 3 shape of boss and adds Hot plate 4, the boss heating dish 4 are fixed in boss 3.

It is truncated cone-shaped that boss 3, which is arranged, in the present embodiment, keeps food heated evenly.

Specifically, further include side heat disk 5, the side heat disk 5 is socketed in the side surface of liner pot body 1.

The side heat disk 5 of the present embodiment setting makes the heating of liner pot body 1 be heated faster evenly.

Referring to Fig. 6, in order to coordinate the boss 3 of 1 bottom of liner pot body, need to coordinate in 2 center portion of bottom-heated disk The structure of corresponding boss 3 does a boss heating dish 4, and the direction of heat transfer of 1 bottom of liner pot body as shown in Figure 6 is when heated From bottom to top, the direction of heat transfer and around boss 3 is existing from bottom to top, also has from inside to outside, such direction of heat transfer, It can effectively reduce by heating food therein central part and external temperature gradient, the temperature of top A points and bottom B points in figure Difference is small, keeps heating more uniform, simultaneously as it is from inside to outside that the heat distributed all can that the heat of 3 part of boss, which is transmitted, By heating food absorption, thermal losses is reduced.

Illustrate referring to Fig. 7, being transmitted by the direction of heat transfer of heating food such as heat when three-dimensional heating, inside liner pot body 1 Shown in arrow.By each section of heating food to the distance of bottom heating dish 2 and boss heating dish 4 all very close to also implying that Thermal gradient is small, each section homogeneous heating.

Embodiment of above is only that preferred embodiments of the present invention are described, not to the utility model Range be defined, under the premise of not departing from the spirit of the design of the utility model, this field ordinary engineering and technical personnel to this The various modifications and improvement that the technical solution of utility model is made should all fall into the guarantor that claims of the utility model determine It protects in range.
