Abstract

The utility model relates to an efficiency energy-saving electric roaster, belonging to an electronic ceramic heater technical field. As indicated in the specification figure, the roaster adopts a PTC heating element and a quartz glass tube element in which an electric heating film is coated as heat sources. The utility model has the advantages of rapid temperature rise rate, high thermal efficiency, long service life, non-contamination for food products, odor free, and high safety. The heating element is arranged at the focus point of a paraboloid or a reflection shield with double curved surfaces. Thus, light can radiate in a certain direction. When the reflection shield is rotated to a front position, a front door is opened. The efficiency energy-saving electric roaster can be used as a heater.

Description

Efficiency energy-saving electric toaster

The utility model relates to " energy-efficient electric oven ", belongs to electronic ceramics heater technical field.

The electrothermal tube that the general employing of the electric oven of Chu Shouing in the market is coated with far ultrared paint is the infrared radiation element.Because power consumption is big, intensification is slow, brings inconvenience to use; Again owing to the easy oxidation of stove silk in electrothermal tube and the pipe, the objectionable impurities that comes off, contaminated food products; And iron taste is especially big, and service life is short.

The purpose of this utility model provides a kind of energy-efficient, quick heating, nonpoisonous and tasteless, long service life, safe and reliable, multi-functional electric oven.

For achieving the above object, electric oven of the present utility model adopt the PTC heating or in be coated with Electric radiant Heating Film quartz glass tube be thermal source.These elements are installed in the focus place of parabola or hyperboloid reflection shield, in case of necessity, reflection shield can be rotated to the baking box anterior locations.

Below in conjunction with drawings and Examples the utility model is described further.

Accompanying drawing is the perspective view of electric oven [the utility model embodiment].

The electric oven that accompanying drawing provides is made up of Qianmen [1], reflection shield [2], heating [3] food net [4], food disc [5], front panel [6], internal box [7], outer case [8], small fan [9], indicator lamp [10], thermosistor [11], power switch [12], timer [13], case pin [14].Wherein: Qianmen [1], indicator lamp [10], thermosistor [11], power switch [12], timer [13] are contained on the front panel [6]; Reflection shield [2], heating [3], food net [4], food disc [5], small fan [9] are contained on the internal box [7]; And outer case [8] is fixed together front panel [6] and internal box [7].

Qianmen, outer case adopt sheet iron to make.Electroplating technology is adopted at the Qianmen, and outer case adopts baking vanish or workmanship of spraying plastics, and internal box, food disc are made with aluminium sheet or corrosion resistant plate.Reflection shield adopts the polishing aluminium sheet, to strengthen reflecting effect.

Heating adopt PTC electronic ceramics rod pipe or in be coated with the quartz glass tube of Electric radiant Heating Film.Configurable parabola in pipe back or hyperboloid reflection shield make the light directed radiation.Pipe is contained in the focus place of reflection shield, and when unlimited Qianmen, reflection shield rotates to anterior locations, can start small fan, and the heat that heating produced just passes to outside the case, uses so baking box can be used as warmer again.

This baking box can be divided into following two types:

1, fixed: reflection shield is fixed, and only makees baking box and uses, and is suitable for office, dining room, food factory etc.

2, rotary type: reflection shield can rotate, and use as warmer winter, is applicable to family.

The power of baking box, family expenses be 500W to 2000W; That public is 2KW to 200KW.

This baking box has been compared following advantage with general baking box:

1, adopt ptc material or in be coated with Electric radiant Heating Film quartz glass tube be heating, do not have the objectionable impurities problem that comes off, thereby nonpoisonous and tasteless, not contaminated food products.

2, programming rate is fast, and thermal efficiency height just can be warming up to several Baidu in tens seconds, and general baking box need give heat 8～10 minutes, so economize on electricity when saving economizes on electricity 30～50% usually.

3, adopt unique reflection shield in the design, make the light directed radiation, improved the effective rate of utilization of heat energy.

4, long service life, the far-infrared radiated property life-span of general baking box is no more than 1000 hours, and in be coated with Electric radiant Heating Film the quartz ampoule life-span surpass 15000 hours, the life-span of ptc material is then longer.

Claims

1, energy-efficient electric oven, its structure is: Qianmen (1), indicator lamp (10), thermosistor (11), power switch (12), timer (13) are contained on the front panel (6); Reflection shield (2), heating (3), food net (4), food disc (5), small fan (9) are contained on the internal box (7); And outer case (8) is fixed together front panel (6) and internal box (7), it is characterized in that: calandria adopt PTC rod pipe or in be coated with the quartz glass tube (5) of Electric radiant Heating Film, this pipe (5) is placed in the focus place of parabola or hyperboloid reflection shield (6).

2, according to the said energy-efficient electric oven of claim 1, it is characterized in that being coated with Electric radiant Heating Film in the far infrared quartz glass tube.
