Description
Technical field
The present invention relates to a kind of micro-wave oven, particularly the hot air convection micro-wave oven of carrying vapour function.
Background technology
Existing overhead type hot blast convection current micro-wave oven as depicted in figs. 1 and 2, the top of body of heater 110 is provided with heat blower 120, heat blower includes thermal-arrest lid 122, fan 123 and heat-generating pipe 121, thermal-arrest lid bottom surface is connected with the top board 141 of furnace chamber 140, inner bottom surface is provided with fan, and the fan shaft core stretches out the thermal-arrest hd top face and cooling motor is in transmission connection; Heat-generating pipe is arranged in the heating chamber between thermal-arrest lid and the furnace chamber.The corresponding fan of furnace chamber top board is provided with the heat conduction mesh.The furnace chamber sidepiece is provided with magnetron 160, cooling motor, cooling fan blade and a plurality of microwave generator spare, and inner top is provided with barbecue tube 150.Bottom of furnace body also is provided with rotary tray motor 170, is connected with rotating disk 130 in the furnace chamber.This is simple and reasonable, but function is little, and the food of cooking out is relatively drier, and mouthfeel is not good.For this reason, businessman designs the hot air convection micro-wave oven of carrying vapour function, utilize an independently steam raising plant generation steam, realize multiple different cooking means such as " steam+hot blast ", " steam+microwave ", " steam+barbecue ", " steam+hot blast+microwave ", so that realize that as much as possible multi-use, a stove are multi-functional.
The mounting means of above-mentioned independently steam raising plant can divide:
1, steam raising plant furnace chamber external: produce high-temperature steam by an external steam generator and import in the cavity again and work.The high-temperature steam utilization rate height of its generation, operation and control are simpler, but complex structure, manufacturing cost are too high.
2, the steam raising plant furnace chamber is built-in: a steam generator is installed in cavity, is made it to produce the high-temperature vapour on-line operation.Its structure is simple than the steam raising plant external, and is producing on the steam all comparatively simply in the operation and control, but its cooking lack of homogeneity, steam utilization are lower when realizing " steam+hot air convection " function.This kind structure is that steam raising plant is placed on cavity bottom, if hot air convection when work steam is inevitable to sinking, and can't follow hot blast to form convection current.Thereby must cause the steam operating efficiency to descend, can't reach best cooking effect.And increased a steam raising plant, making structure numerous and diverse has also increased manufacturing cost accordingly.
Disclose a kind of multifunction microwave oven that has superheated steam among the China Patent No. ZL200620053579.9, on the basis of conventional microwave oven, increased common steam device and convection heating system generation superheated steam, common steam and convection current hot blast.Be provided with boiler in prime with two heat-generating pipes, it produces about 100 ℃ common steam, common steam enters the Convective Heating chamber that is provided with two heat-generating pipes then, and common steam is done further heating, produces the superheated steam of 100 ℃＜t≤400 ℃.More than four combinations that heat-generating pipe is different, just produced superheated steam, common steam and convection current hot blast.And these functions also can make up with microwave, produce new function again, realize more cooking method.Especially, the combination of steam, superheated steam and microwave both can overcome the defective that pure microwave cooking food becomes dry, and can realize the delicious food of food and culinary art fast again.The more important thing is that superheated steam can remove fat unnecessary in the food and salt, cook out the food of low-calorie, low salt, thereby realize " healthy culinary art ".Because aqueous water enters in the convection heating system heating chamber and can produce steam, and the micro-wave oven of this structure both had been equipped with convection heating system, and steam unit is installed again,, increased mounting hardness again so not only improved the cost of making.
Summary of the invention
Purpose of the present invention be intended to provide a kind of simple in structure, the cost cost is low, produce easily, and does not establish the hot air convection micro-wave oven that steam raising plant but can use the carrying vapour function of the steam cooking, to overcome weak point of the prior art.
Press the hot air convection micro-wave oven of a kind of carrying vapour function of this purpose design, comprise that the top is provided with the body of heater of heat blower, be provided with water storage box in the body of heater, its architectural feature is that water storage box is communicated with pumping conduit, the pumping conduit other end stretches in the heating chamber of heat blower, realize aqueous water directly by in the high temperature heating chamber to produce high-temperature steam.
Described water storage box is arranged on a side of furnace chamber, is connected with pumping conduit by water pump, and the pumping conduit other end is provided with nozzle and stretches in the heating chamber of heat blower.
Described heat blower includes thermal-arrest lid, fan and heat-generating pipe, and thermal-arrest lid bottom surface is connected with the furnace chamber top board, and inner bottom surface is provided with fan, and the fan shaft core stretches out the thermal-arrest hd top face and cooling motor is in transmission connection; Heat-generating pipe is arranged in the heating chamber between thermal-arrest lid and the furnace chamber.
The corresponding fan of described furnace chamber top board is provided with the heat conduction mesh, and corresponding pumping conduit nozzle is provided with concave surface.
The present invention is delivered to the aqueous water under the normal temperature in the water storage box in the hot air generator, cavity temperature can reach 250～350 ℃ (this temperature meets steam fully and produces condition) during because of the heat blower normal operating conditions, so in heat blower, very easily produce high-temperature steam, by fan component the high-temperature steam that produces is delivered in the furnace chamber again, in furnace chamber along with hot blast forms convection current, the high-temperature steam that produces in the heat blower is cooked uniformly to food, simplified steam hot wind convection current microwave oven, reduce manufacturing cost.And high-temperature steam can to allow furnace chamber inwall dirt oil defect obtain moistening fully, greatly reduce the furnace chamber inwall and clean difficulty.For the output of the better control water yield, be provided with nozzle in the water side of pumping conduit; Furnace chamber top board corresponding nozzle is provided with concave surface, and Sheng is carried aqueous water and it is fully evaporated, and effectively prevents the direct contacting foodstuff of aqueous water.The furnace chamber top of micro-wave oven is equipped with heat blower and barbecue tube, all can carry out physical heating to food, the magnetron that cooperates furnace chamber again can provide the multiple different cooking means that meet properties of foods such as " steam+hot blast ", " steam+microwave ", " steam+barbecue ", " steam+hot blast+microwave ".Each working link therebetween can make entire work process without any confusion by automatically controlled plate program setting.It is simple and reasonable, homogeneous heating, efficiency height, cleaning easily, the cost cost is low, have multiple cooking function simultaneously.
