Abstract

The utility model provides a household electric heating roaster, comprising a box body, an electric heating tube arranged in the box body and a food bracket allocated above the electric heating tube. The two sides of the box body are assembled with protective covers, electric fans are installed on the lower part positions in the protective covers, and the front face of the box body is provided with an operating panel which is assembled with a power switch, a power indicator, a temperature control knob and a power plug. The using is convenient and sanitary and the baking efficiency is high for the heating mode of the temperature of the electric heating tube can be regulated is adopted by the utility model. The allocated electric fans can effectively control the lower part of the box body always to be in relative lower temperature, so the attachment on the inner surface of the box body is avoided to combust and coking under the high-temperature function, the contamination of the environment caused by the produced fume in the baking process is diminished, and the problem that the box body after being used is difficult to be washed is solved.

Description

Domestic electric heating formula barbecue box

Technical field

The utility model relates to kitchen utensils, is a kind of domestic electric heating formula barbecue box specifically.

Background technology

At present, being used for the barbecue apparatus of baking food on the market, mainly is to be the barbecue box of thermal source with the combustion charcoal, and it adopts the opened type body structure, during use the charcoal that ignites is placed the bottom in the case, and rack is set above casing is used for placement and treats roast food.The problem of its existence is the trouble of igniting of charcoal, the process of burning can produce a large amount of cigarettes and flying dust, not only caused environmental pollution but also influenced the edible health of baking food, and since the charcoal fire temperature can't regulate, be easy to cause food not yet done or burned, make the baking quality of food restive.For solving the problem that combustion charcoal barbecue box exists, also disclose some in the prior art and adopted the electrically heated uncovered type barbecue box of, but, the difficult quality of baking food has been met the demands because it does not solve the adjustment problem of barbecue.And too high because of the temperature of baking box bottom, cause under the baking process junk at the bottom of case, to burn and form coking, thereby produce smoke pollution of environment and cause baking box to clean difficulty with the back.

Summary of the invention

The purpose of this utility model is at the problems referred to above, and a kind of electrothermal tube heating of adopting temperature adjustable is provided, and can effectively avoid the domestic electric heating formula barbecue box of burning of tank wall attachment and formation coking.

The technical solution of the utility model is: a kind of domestic electric heating formula barbecue box, the food carriage that it includes casing and places the electrothermal tube in the casing and be disposed at the electrothermal tube top, both sides at described casing are equipped with protective cover, in protective cover, fan is installed, is equipped with the control panel of charged source switch, power supply indicator, temperature control handle and attaching plug in the front of casing in lower position.

The technical solution of the utility model also comprises: be arranged to the plate plug-in mounting structure at the bottom of the case of described casing.

The utility model is compared with existing like product, has following advantage:

1, adopts the electrothermal tube mode of heating, just can reach the required temperature of barbecue in several seconds turning on the power switch, easy to use, and because heating-up temperature is even, can be easily according in the baking process, temperature being regulated by the different characteristics of roast food, can effectively avoid being given birth to the generation of ripe uneven phenomenon, fully satisfy the requirement of user's different taste by roast food.

2, adopt the body structure that disposes fan in the both sides, bottom, can improve the efficiency of heating surface that electrothermal tube is opposite to top food, and effectively control lower box and be in relatively low temperature all the time, thereby avoid the tank surface attachment to be subjected to high temperature action burning and coking, reduce of the pollution of barbecue process smog, solve the problem of cleaning difficulty with rear box environment.

3, adopt plate base for convenience detach, the removing that the case prodelta clay is deposited dirt is easy, helps the sanitation and hygiene of barbecue box.

Description of drawings

Fig. 1 is that the distant relative uses electrothermal barbecue box structural representation.

Fig. 2 is the circuit diagram of this barbecue box.

The specific embodiment

In conjunction with the accompanying drawings the specific embodiment of the present utility model is described:

Provide as accompanying drawing 1, the utlity model has the rectangular box 1 of uncovered type, be set to level by the upper part and be placed with many electrothermal tubes 2 in casing, it is provided with food carriage 3 above casing above electrothermal tube.Be respectively fitted with protective cover 4 in the both sides of casing, the top of its protective cover is provided with opening, and as the casing handle, it is corresponding with the air inlet on the wall box in lower position fan 5 to be installed in protective cover.The front of casing is provided with control panel 10, the attaching plug 9 that is equipped with power switch 6, power supply indicator 7, temperature control handle 8 on its panel and draws through power line.

Be arranged to detachable structure at the bottom of the case of the utility model with casing 1, conveniently to drop to the cleaning of case bottom surface dirt, its concrete structure is that both sides are provided with inserting groove below casing, through inserting groove assembling plate 11.

Accompanying drawing 2 has provided the circuit structure diagram of this barbecue box, and its circuit is made of three loops by K switch control incoming transport 220V power supply, wherein a route divider resistance R ₁With light emitting diode D ₁Series connection constitutes, and is attempted by between the fire, ground wire of power supply the state of indication power supply; Another road is by transformer B step-down, and the voltage of secondary coil output is through bridge full wave rectifier D _zRectification and capacitor C ₁Be filtered into DC voltage, drive the fan F of two parallel connections ₁, F ₂Work; Tertiary circuit is by electrothermal tube R _D, inductance L and controllable silicon T be composed in series; On the inductance and connect the configuration resistance R ₃Adjustable resistance R _w, and through series connection divider resistance R ₂After, an end is by bilateral diode D ₂Link the control end of controllable silicon T, the other end is through capacitor C ₂Link the ground wire of power supply.

When this barbecue box uses, make K switch closure in the circuit, diode D by pressing power switch 6 on the control panel ₁Luminous, the indicator lamp 7 on the panel is bright, shows that barbecue box is in running order, and fan 5 rotates simultaneously, electrothermal tube 2 heatings.Adjust resistance R by rotational temperature control handle 8 _w, make to be allocated in R _DOn voltage change, realize adjustment to electrothermal tube 2 heating temps.

When the utility model is specifically implemented, can on the lateral surface of casing 1, assemble auxiliary equipments such as seasoning box rack as required.
