Abstract

The utility model discloses a wire-pendant type electric stove which is suitable for various cookers. In the wire-pendant type electric stove, resistance wires are suspended at the middle of an anti-radiation disk, and the electric insulation and fixation can be made via an insulating support and a metal support. Some radiated heat of the resistance wires is directly radiated to a black heated cooker bottom, and the other radiated heat of the resistance wire penetrates through the clearances of the resistance wires and the optical channel of the support and then directly radiate to the heated cooker bottom by the reflection of a reflecting disk. The height from the top edge of the reflecting disk to support can be adjusted, so the heating resistance wires of various kinds of cookers can be completely covered. The temperature rise of the wire-pendant type electric stove is quick; compared with an ordinary electric stove, the efficiency of heat utilization can be improved by 25-30%; the wire-pendant type electric stove is suitable for a pan as well as a cooker with a paraboloidal bottom.

Description

Wire-pendant type electric stove

The utility model belongs to domestic electric-heating stove.

Existing electric heater can be divided into two big classes from the transfer mode of heat: a class is a conduction-type, protects as electric meal; Another kind of is the radiation conduction-type of holding concurrently, as ordinary porcelain pallet resistance wire electric furnace.Its shortcoming of conduction-type electric furnace is to join special-purpose pot.The radiation conduction-type ordinary porcelain pallet resistance wire electric furnace of holding concurrently has following shortcoming: 1. a suitable pan; 2. the porcelain tray quality is too big, and heat absorption is many, and it is slow to heat up; 3. the emissive power of porcelain tray own is bigger, and after temperature raise, the bottom surface radiant power was bigger, again less than good reflection.For above-mentioned reasons, ordinary porcelain pallet resistance wire electric furnace heat utilization efficiency is very low.

The utility model purpose is: a kind of suspension-wire type electric furnace is provided.This electric furnace is applicable to the heating of various pot, and light weight, quick heating, heat dissipation are few, the heat utilization high efficiency.By to this purpose, this electric furnace is without metal heat-generating disc or porcelain tray, directly with the resistance wire emittance of generating heat, and possesses good reflection and adiabatic apparatus.

Formation of the present utility model is, conventional, electric-resistance silk density equably around or the dish on insulating support, plane that resistance wire surrounded or three-dimensional surface are long-pending greater than the surface area of resistance wire own, guarantee the maximum operating temperature that radiation temperature is not higher than resistance wire and is allowed, it is long-pending that the optical channel area of electric insulation support is slightly less than the radiation cross-section of electric furnace.Be fixed on by the fixing resistance wire dish of insulating support on the fixed support of a reflection disk middle upper part, power supply passes reflecting disc and resistance wire joins.Be used for fixing the support of the support double as pot of resistance wire dish, its optical channel area be not less than be used for around or the optical channel area of electric insulation support of dish resistance wire, the fixed form of this support has two kinds: a kind of is to be fixed on the round wall of reflection disk; Another kind is to be fixed on the pillar that passes reflection circle disk center.A kind of fixed form before adopting, power line just penetrate from reflection disk sidewall, adopt a kind of mode in back, and power line just penetrates from centre strut.The reflection disk is to be processed by the bigger metal of electrical conductivity such as aluminium, copper, silver, and reflecting surface is through polishing.Reflecting disc maintains the distance of a minimum from resistance wire, pass through air adiabatic, to guarantee that few heat passes on the reflecting disc, but plane, reflecting disc top edge place is plan range up-down adjustment within the specific limits on the resistance wire support, the method of regulating has two kinds: scheme 1. is at reflecting disc top edge overcoat one ring, surely close by screw and reflecting disc, but upper and lower translation during rotation; Scheme 2. is to adorn a pillar in the middle of reflecting disc, and reflecting disc can move up and down, and changes the purpose of plane, reflecting disc top edge place from the support plan range to reach.This adjusting device, when different pot types were used electric furnace, reflecting disc can both cover emission source fully, avoided radius to penetrate in seam, the waste energy.This electric furnace is that right and wrong white is answered in the bottom of a pan to unique requirement of pot, when the pot in the bottom of a pan of non-white is placed on the above-mentioned electric furnace, the resistance wire heating, the energy of radiation directly is mapped on the bottom of a pan towards the one side in the bottom of a pan, the bottom of a pan that is in low temperature absorbs fully, and the one side in the back of the body the bottom of a pan reflects through reflecting disc, most by space between the resistance wire and the direct projection of support optical channel to the black the bottom of a pan, the non-white the bottom of a pan that is in low temperature absorbs fully.By radiation and antiradiation, finish heat exchanging process like this.

The utility model and the difference of existing electric furnace are that there is intermediate material in the heat transfer process of existing electric furnace, utilize intermediate material such as heat-generating disc and slot type porcelain tray to conduct and radiation more again.Intermediate material conduct again with reradiative process in because intensification itself will absorb a lot of heats, and the utility model is directly to utilize resistance wire heating radiations heat energy, has avoided intermediate material to absorb heat; Existing electric furnace does not have special reflection unit, the utility model is taked special reflecting disc, and reflectivity can be up to more than 95%, and makes reflecting disc from thermal source larger distance be arranged, by air adiabatic, guaranteed that reflecting disc works at a lower temperature.To guarantee that the unlikely rising because of temperature of reflectivity reduces; Have electric furnace now or only be applicable to special-purpose pot, or only be applicable to pan, and the utility model there is reflecting disc high temperature adjusting device, applicable to various pot types.Because the utility model has above-mentioned improvement, its advantage is light weight, quick heating, easy to use, and efficiency of utilization significantly improves, and under same condition, adopts boiled 2 kg of water of the utility model only to use 15 minutes, and will spend 24 minutes with existing common electric furnace.

Now in conjunction with the accompanying drawings the utility model is done further careful description:

Fig. 1 is the front view of a kind of concrete structure of the utility model, and Fig. 2 is the utility model A-A profile, and Fig. 3 is the utility model arm B-B profile, and Fig. 4 is that the utility model high temperature resistant resistance silk porcelain is around the ring front view.
