Steam raising plant
Technical field
The utility model relates to a kind of steam raising plant, especially a kind of steam raising plant that is used for heaters such as micro-wave oven, baking box.
Background technology
At present in the life, the user generally can use the enclosed type heater that food is heated, micro-wave oven for example, and baking box etc., but in above-mentioned heating process, cause the water loss of food easily, cause harmful effects such as food drying.For addressing the above problem, Chinese patent 03127539.7 has disclosed a kind of thermatron that has steam generating function, by supply steam and frequency electromagnetic waves (microwave) in heating clamber heating object is heated, steam raising plant in the above-mentioned patent comprises the steam generation unit that is used for producing steam in heating clamber, and be used for the water pot that supplies water to above-mentioned steam generation unit, wherein the steam generation unit comprises the evaporating dish that is positioned at heating chamber, be arranged on the evaporation pan heater that evaporating dish is heated of evaporating dish downside, and the reflecting plate that the reflect radiation heat of this heater to the cross section of evaporating dish is slightly taken the shape of the letter U constitutes.The operation principle of said structure is: water pot supplies water in evaporating dish earlier, the heat that evaporation pan heater produces is radiated the bottom of evaporating dish behind baffle reflection, after evaporating dish absorbs heat, heat is passed to water in it gradually, after reaching uniform temperature, produce steam, thereby reach the effect that heating chamber is provided steam.
The steam raising plant defective of said structure is: the heat that heater produces, pass to evaporating dish, evaporating dish passes to the interior water of evaporating dish after absorbing heat again, and most of zone of evaporating dish is an open area, therefore, it is slower that water heating process steam produces, and heat waste is more.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of thermal loss little, produces fast, the simple and reasonable steam raising plant of vapor (steam) velocity, to overcome weak point of the prior art.
The technical scheme in the invention for solving the above technical problem is: a kind of steam raising plant, comprise that heater, the water tank that is used for supplying water, the steam that is used for that heater is produced spray to the steam jet in the heater in heater, connect by tube connector between the water inlet of heater and the water tank, steam jet is connected with heater by steam output pipe, and wherein above-mentioned heater is hollow form.
Above-mentioned tube connector is a U type pipe.
Above-mentioned water outlet of water tank place is provided with check valve and reverse check valve.
Above-mentioned heater upper end is provided with the steam pressurized piece.
The bottom of above-mentioned steam pressurized piece can be provided with the steam spacer.
The two ends of above-mentioned heater are provided with fixed mount.
The utility model is owing to adopt the structure of hollow heater, and when water flow in the heater, heater heated generation steam to water, and because of the water heating surface area is big, therefore, steam produces fast, and thermal loss is less.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Among the figure: 1 is that water tank 1,2 is that U-shaped tube connector, 3 is that heater, 4 is that water proof exhaust sheet, 5 is that steam pressurized piece, 6 is that fixed support, 7 is that steam output pipe, 70 is that steam jet, 8 is water check valve, 9 reverse water check valves.
Referring to Fig. 1, this steam raising plant, the water tank 1 that comprise heater 3, is used for supplying water in heater, the steam that is used for that heater is produced spray to the steam jet 70 in the heater, connect by U-shaped tube connector 2 between the water inlet of heater and the water tank, steam jet 70 is connected with heater by steam output pipe 7, and wherein above-mentioned heater is hollow form or the disk body that similarly generates heat.
Above-mentioned water tank 1 can place heater such as micro-wave oven, outsides such as baking box, its underpart is provided with delivery port 10, reverse water check valve 9 is installed at the delivery port place, oppositely water check valve 9 is connected with water check valve 8, water check valve 8 is connected with U-shaped tube connector 2, when removing water tank 1, the water of U-shaped tube connector 2 can not overflow under water check valve 8 controls, the other end of U-shaped tube connector 2 is connected with heater 3, and heat-generating pipe 3 is vertically placed, and is provided with steam pressurized piece 5 thereon in the port, the lower end of steam pressurized piece 5 is connected with water proof exhaust sheet 4, the upper end of steam pressurized piece 5 is connected with steam output pipe 7, and the end of steam output pipe 7 is provided with steam and sends out nozzle 70, and steam pressurized piece 5 can increase the steam pressure in the body, to increase the temperature of steam, water proof exhaust sheet 4 is used for water and the steam in the isolated tube, makes in the water isolated tube, prevents that water from flowing into steam jet.
In addition, the outside, the two ends of heat-generating pipe is provided with fixed support 6 up and down, is used for steam raising plant is fixed in the heating chamber.
