Abstract
The utility model discloses a heat accumulation and preservation type electric heater, comprising a heating layer. A resistance wire is arranged in the heating layer. A heating layer shell body and a metal installation disc in contact with a heating utensil are sequentially arranged at the upper part of the heating layer. A heat-accumulation insulation layer and a heat insulation and preservation layer are sequentially arranged at the lower part of the heating layer. After effectively and quickly heating an object to certain temperature, the heat accumulation and preservation type electric heater continuously carries out heating only by utilizing heat energy stored at the bottom part and the periphery of the heater, or keeps the object under constant temperature at appropriate time; compared with the general electric heater, the heat accumulation and preservation type electric heater has the characteristic of leading long heat-preservation time without power consumption.
Description
Technical field
The utility model relates to a kind of heater that is used on the firing equipments such as electric rice cooker, electric food warmer, specially refer to a kind of will heat thing be heated rapidly to only utilize after the uniform temperature this heater base and around stored heat energy continue heating or in due course between in make the heat-storage heat-preserving type electric heater of heating thing constant temperature.
Background technology
At present, bottom electrical heaters such as general electric rice cooker, electric food warmer adopt resistance wire are fixed in the metal tube with insulating heat-conduction material, adopt extrusion process to be processed as one metal tube and bottom heating plate again, rely on the heat conductivity principle directly heating plate to be heated.The main bad point of general electric heater shows following several respects: 1, the heating plate bottom reaches the heat major part that is produced all around and distributes externally environment, and heat utilization efficiency is low, probably only accounts for about 40%-50%; 2, be heated to uniform temperature when heating thing, the heating plate temperature descends soon behind the deenergization, and heat-insulating property is poor, and insulation then can only be interrupted energized and heating plate heated the waste electric energy as needs.3, METAL HEATING PROCESS dish processing characteristics requires height, needs heat to waste energy in work flow; Because of heat can produce a large amount of pollutions, contaminated environment; And in work flow, be easy to generate scrap, percent defective height, waste metal material.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provide a kind of will heat thing be heated rapidly to only utilize after the uniform temperature this heater base and around stored heat energy continue heating or in due course between in make the heat-storage heat-preserving type electric heater of heating thing constant temperature.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of heat-storage heat-preserving type electric heater, it comprises heating layer, resistance wire is installed in the heating layer, the top of described heating layer be provided with according to this heating layer housing and with the contacted metal mounting disc of heating vessel, the bottom of described heating layer is provided with heat accumulation insulating barrier and insulating according to this;
As a modification of the embodiment above, be provided with between described heat accumulation insulating barrier and the insulating and be used for fixing the metallic plate that usefulness is installed; Adopt high-temperature adhesives to be bonded between described heat accumulation insulating barrier and the metallic plate; Described metal mounting disc the surface be provided with several small boss;
Further improvement as to above-mentioned execution mode is equipped with metal platen on the described insulating; Adopt screw to install between described metallic plate, insulating and the metal platen.
The beneficial effects of the utility model are: this product effectively will heat thing be heated rapidly to only utilize after the uniform temperature this heater base and around stored heat energy continue heating or in due course between in make heating thing constant temperature, compare with general electric heater, have the long characteristics of temperature retention time under the situation of not consuming electric power, can keep food to seethe with excitement continuously in addition at fluidizing point, if be used on the electric cooker sustainable boiling 30-40 minute, if be used on the electric pressure cooker sustainable boiling 60 minutes, the nutrition that can't destroy food can be not burned food yet.At normal temperatures, can be incubated 3-4 hour food is reached more than 50 ℃, have characteristics such as energy-conservation, not power consumption, temperature retention time are long, in addition,, in work flow, not pollute the environment, also waste material not because draw materials environmental protection, convenience when making this product.Thereby can be widely used in the making of firing equipments such as electric rice cooker, electric food warmer.
Description of drawings
Following accompanying drawing further specifies the utility model.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a structural representation of the present utility model;
Embodiment
With reference to Fig. 1, Fig. 2, a kind of heat-storage heat-preserving type electric heater, it comprises heating layer 6, resistance wire 1 is installed in the heating layer 6, the top of described heating layer 6 be provided with according to this heating layer housing 7 and with the contacted metal mounting disc 8 of heating vessel, the surface of metal mounting disc 8 is provided with several small boss 81, this design effectively guarantees the working strength of metal mounting disc 8, in addition, can also prevent to scratch; The bottom of described heating layer 6 is provided with heat accumulation insulating barrier 5 and insulating 3 according to this.
This product is used for fixing the metallic plate 4 that usefulness is installed for the ease of installing, being provided with between described heat accumulation insulating barrier 5 and the insulating 3; Adopt high-temperature adhesives to be bonded between described heat accumulation insulating barrier 5 and the metallic plate 4.In addition, on the described insulating 3 metal platen 2 is installed; Adopt screw 9 fixed installations between described metallic plate 4, insulating 3 and the metal platen 2.
The operation principle of this product is: resistance wire 1 heating is by heating layer 6 insulating heat-conduction materials conduction heating heating layer housing 7, and heating layer housing 7 is by heat conduction heating of metal mounting disc 8, and metal mounting disc 8 is by contact heat conduction heating vessel bottom; In addition, heat accumulation insulating barrier 5 is with the heat collection and the storage of the conduction of heating layer 6 bottoms, and insulating 3 is effectively stored with standby heat accumulation insulating barrier 5 stored heat energy; When at the bottom of the heating vessel bottom temp during in heat accumulation insulating barrier 5 temperature, heat accumulation insulating barrier 5 stored heat energy heat heating layer 6 by conduction, heating layer 6 Heat Conduction Materials conduction heating heating layer housing 7, heating layer housing 7 is by heat conduction heating of metal mounting disc 8, and metal mounting disc 8 is by contact heat conduction heating vessel bottom.Realize the purpose that recuperation of heat utilizes.
By in electric rice cooker embodiment, when cooking, water temperature reaches preset temperature (about 80 ℃) and need not the water boiling, this moment deenergization, heat-storage heat-preserving type electric heater can will be collected the heat of returning and continues to send by being arranged on the heat accumulation insulating barrier, and heat is strengthened gradually in 10 minutes, until the water boiling meal is boiled; When pot congee Baoshang, water temperature reaches preset temperature (about 90 ℃) and need not the water boiling, deenergization, and heat-storage heat-preserving type electric heater can continue to send with collecting the heat of returning, and water is in fluidized state about 30 minutes.Owing in this product, be provided with insulating, at normal temperatures, can be incubated 3-4 hour food is reached more than 50 ℃.
