Description
Technical field
The utility model relates to a kind of electric cooker, particularly provides the rapid and precise control temperature of a kind of energy, has the ceramic electric cooker of overtemperature prote effect.
Background technology
Electric cooker is an indispensable daily life necessity in people's daily life; present widely used ceramic electric cooker all adopts the bottom temperature-sensitive; temperature detector contact or noncontact inner bag bottom surface; because of the ceramic liner coefficient of heat conduction and temperature-sensitive inaccurate etc.; cause praising the system overlong time; the thermal efficiency is low, and the temperature-sensing element of overtemperature prote all is unsettled in heat space, makes it have following shortcoming:
1, temperature-sensing element heat conduction overlong time and temperature-sensitive are inaccurate;
2, overtemperature prote, temperature is inaccurate, causes part of damage and burns sudden and violent inner bag.
The utility model content
Main order of the present utility model is to overcome deficiency of the prior art, the rapid and precise control temperature of a kind of energy is provided, has the ceramic electric cooker of overtemperature prote effect.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of ceramic electric cooker, it comprises: enclosing cover, middle cover, inner cap, attemperator and shell, wherein, be provided with temperature-sensing element between described middle cover and the inner cap, cover during temperature-sensing element is fixed on this, this inner cap is provided with the steam exhaust-gas hole.
Cover in being somebody's turn to do and also be provided with the sealing ring that matches with the ceramic liner mouth.
This middle cover is provided with the hole, and this is equipped with silica gel sheath in the air, and temperature-sensing element wears and is arranged in the silica gel sheath on this.
This attemperator comprises metallic enamel muff, the second metal heat preservation cover, the 3rd metal heat preservation cover, the first metal heat preservation cover, wherein, between metallic enamel muff and ceramic liner and second metal heat preservation cover, all form insulation heat accumulation storehouse between the 3rd metal heat preservation cover and first metal heat preservation cover, between overlapping, this second metal heat preservation cover and the 3rd metal heat preservation be filled with insulation material.
This metallic enamel muff is connected by support point with insulation heat accumulation storehouse inner bottom part.
This metallic enamel muff is connected by support point with annular heat-generating pipe.
The center fixation of this metallic enamel muff and second metal heat preservation cover is equipped with movable location heating column, the top of this location heating column contacts with ceramic liner, the other end is equipped with down temperature-sensing element, when the location heating column moves downward, driving the metallic enamel muff moves downward, simultaneously, again because fix between this location heating column and second metal heat preservation cover and the 3rd metal heat preservation cover, make it can drive insulation heat accumulation storehouse and change.
This inner cap is provided with two or more steam exhaust-gas hole.
Because the utility model has adopted in the gas that this temperature-sensing element is directly open and the interior steam of ceramic liner is one and has been provided with down temperature-sensing element and four layers of muff, makes to the utlity model has following advantage:
1, rapid and precise control temperature;
2, reach the overtemperature prote effect, prevent part of damage and burn broken inner bag;
3, high insulating effect.
Below in conjunction with drawings and Examples the utility model is further described.
Description of drawings
Fig. 1 is the surface structure schematic diagram of the utility model embodiment ceramic electric cooker.
The specific embodiment
As shown in Figure 1, the described ceramic electric cooker of present embodiment comprises: enclosing cover 1, go up encircle 7 in temperature-sensing element 2, silica gel sheath 3, middle cover 4, sealing ring 5, inner cap 6, the plastics, shell 8, D layer metal heat preservation material 9, C layer metal heat preservation material 10, B layer metal heat preservation material 11, electrothermal dark-red pottery inner bag 12, insulation material 13, A layer metallic enamel muff 14, annular heat-generating pipe 15, base 16, location heating column 17, temperature-sensing element 18 and steam exhaust-gas hole 19 down; Wherein:
This middle cover 4 is provided with hole, be fixed with silica gel sheath 3 in this hole, wear in this silica gel sheath 3 and be provided with temperature-sensing element 2, middle cover 4 is provided with and the corresponding sealing ring 5 in the top of electrothermal dark-red pottery inner bag 12, make and form an annular seal space between middle cover 4 and the inner cap 6, this inner cap 6 is provided with two steam exhaust-gas holes 19, and the sealing chamber is connected with electrothermal dark-red pottery inner bag 12, and this temperature-sensing element 2 is open in annular seal space.Make temperature-sensing element 2 on this can directly experience temperature in the annular seal space, thus quicker and control temperature more accurately.
Annular heat-generating pipe 15, A layer metallic enamel muff 14 and B layer metal heat preservation overlap between 11 threes and are incubated heat accumulation storehouse with the bottom and relative the formation from having living space of outer wall of electrothermal dark-red pottery inner bag 12 on every side, because of the thermal conductivity of electrothermal dark-red pottery inner bag 12 relatively poor, so the heat that utilizes A layer metallic enamel muff 14 that annular heat-generating pipe 15 is sent more concentrated and more directive with the 12 heat conduction of electrothermal dark-red pottery inner bag.
All form insulation heat accumulation storehouse between A layer metallic enamel muff 14 and electrothermal dark-red pottery inner bag 12 and the B layer metal heat preservation cover 11, be filled with insulation material 13 between this B layer metal heat preservation cover 11 and the C layer metal heat preservation cover 10.Like this, the multi-layer heat preserving material makes the lost minimizing of heat, and system time and reduction skin temperature effectively reduce to stew.
A layer metallic enamel muff 14 centers wear location heating column 17 are installed; one end of this location heating column 17 contacts with electrothermal dark-red pottery inner bag 12 bottoms; the other end is equipped with down temperature-sensing element 18; when the water of electrothermal dark-red pottery inner bag 12 dryouies; the temperature of electrothermal dark-red pottery inner bag 12 bottoms raises rapidly; location heating column 17 is passed to down temperature temperature-sensing element 18 simultaneously, and this protective device can effectively suppress improper use and the damage that causes.
This A layer metallic enamel muff 14 is connected by support point with insulation heat accumulation storehouse inner bottom part; This A layer metallic enamel muff 14 is connected by support point with annular heat-generating pipe, has reduced contact area like this, has avoided heat to hoard.
In sum, the utility model from application target, on the usefulness, viewpoint such as progressive and novelty sets forth, the practical improvement that it has, function enhancement and practical important document that novel Patent Law is emphasized have been accorded with, shown in the implementation and accompanying drawing that the utility model is above, be one of the utility model preferred embodiment, be not to limit to the utility model with this, be with, such as with approximate, identical person such as structure of the present utility model, device, feature, all should belong to of the present utility model founding within purpose and the claim.
