A kind of fireless cooker of interlayer
Technical field
The utility model relates to a kind of pot of kitchen utensils, particularly a kind of fireless cooker.
Background technology
Fireless cooker, be used for keeping in a long time warm of food of cooking so that when noon is edible, still steaming hot, sweet-smelling good to eat.Thereby under some occasion, be widely used.Existing fireless cooker adopts the method that the pot body is wrapped up, and completely cuts off scattering and disappearing of heat with different insulation materials.Obviously, this can make the pan structure heaviness, and effect is not very good yet.Also with good grounds thermos bottle principle, employing vacuum heat-insulating mode.89216306.2 of ZL are called the utility model patent of " vacuum interlayer fireless cooker " (notification number CN 2057078 U day for announcing 1990-05-16), a kind of vacuum heat-preserving pot is disclosed, it is characterized in that pot wall is made up of internal layer and outer two layers of walls, the centre is a vacuum interlayer, inside and outside two layers of walls can be made with aluminium sheet or the welding of corrosion resistant plate drawn, only this does not refer to the specific embodiment as to disclosed flesh and blood.From patent document, can't see and how to implement, make interlayer reach vacuum.Made us more guess undoubtedly, though still fail to assert, it can't implement or disclose insufficient, does not elaborate really.Only disclose a conception of species, people are through some creationary thinking, and open the scoring is clear, are when making or when use obtains vacuum, and then think deeply it and how to obtain.Several times try to figure out, can guess that it is when making the pot body interlayer to be vacuumized, sealing then surely not is when using, and mixes a vavuum pump again and vacuumizes, and is so loaded down with trivial details.Nature, it is to make complexity, the quality instability, heat insulation effect differs, and heat transfer efficiency also is difficult to regulate, and the perfect place of many improvement is still arranged.
The utility model content
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part, and provides a kind of simple in structure, makes easily, and security is good, and is easy to use, the fireless cooker of the interlayer of heat preservation energy-saving.
The purpose of this utility model can reach by following measure:
A kind of fireless cooker of interlayer, comprise a pot body, handle, pot cover and pot lid handle, handle is fixed on the both sides on the external wall of pot, pot lid handle is installed on the end face of pot cover, pot cover closely fastens with the pot body, it is characterized in that, described pot body includes inner bag and chuck, this forms between the chuck of a circle around inner bag between the two, top between this chuck, be with the chuck aperture that leads to the chuck outside, in between chuck below this chuck aperture, a check valve is installed separately, and this check valve passes through screw thread, be connected separately on the valve body bolt, and this valve body bolt is welded on below the above-mentioned chuck aperture, and the steam vent on the valve body bolt center line is same center line with this chuck aperture and communicate; Described check valve includes valve body, spring and steel ball, and valve inner is a columniform inner chamber, and the inner chamber bottom is a round taper hole that leads between chuck, on round taper hole, place steel ball, suppressed by spring above the steel ball, when setting spring reached 6KPa at air pressure, steel ball was raised.
The inside of above-mentioned pot cover has between the interlayer of one deck sealing; The bottom of above-mentioned pot body is compounded with the bottom surface laminate that one deck is made by metal material.
On the outer of above-mentioned pot cover bottom surface, the position corresponding, be provided with the splashproof groove of a circle indent with the chuck aperture.
Fireless cooker of the present utility model has following advantage:
1, simple in structure, make simple and easy.Fireless cooker of the present utility model, in its interlayer, the acquisition of vacuum is not during fabrication, but obtains the partial vacuum under user mode.Thereby, simplified manufacture craft greatly, only need in chuck valve body with a check valve, by being threaded, being screwed on the valve body bolt and getting final product, the sealing of chuck aperture only depends on spring roof pressure steel ball, covers funnelform round taper hole; Between the chuck of pot interlayer body, need not when making, to vacuumize specially and then seal.
2, easy to use, security is good, and is energy-efficient.The temperature control of the utility model fireless cooker, more stable.By the setting of spring tension, internal gas pressure is below 6KPa between the control chuck, and overvoltage gas can be discharged by the chuck aperture from steam vent when surpassing, make fireless cooker can overtemperature, superpressure; And has an energy-saving effect.When the air pressure between chuck was negative pressure, steel ball covered the round taper hole in the valve body under the spring force effect, and outside gas is difficult for entering, and is in the partial vacuum state between chuck, plays the effect of heat-insulation and heat-preservation.Because pot body, pot cover all are interlayers, heat is difficult for passing heat preservation energy-saving in the pot.
Below in conjunction with drawings and Examples the utility model is done further non-limiting narration.

Among each figure, the 1st, pot body, 2,2 ' is handle, the 3rd, pot cover, the 4th, pot lid handle, 5,5 ' is check valve, 6,6 ' is the valve body bolt, the 11st, and the inner bag of pot, the 12nd, chuck, the 13rd, the bottom surface laminate, the 121st, between chuck, 120,120 ' is the chuck aperture, the 30th, between the interlayer of pot cover, the 35th, splashproof groove, the 51st, valve body, the 52nd, spring, the 53rd, steel ball, the 510th, the round taper hole in the valve body, 610,610 ' is the steam vent of valve body bolt.
The specific embodiment
Make a fireless cooker with corrosion resistant plate, comprise pot body 1, handle 2,2 ', pot cover 3 and pot lid handle 4, this pot body 1 include inner bag 11 and chuck 12, promptly Guo internal layer is an inner bag, skin is the outer surface of chuck, forms between chuck 121 between inside and outside layer, in pot body 1 bottom, compound last layer bottom surface laminate 13, pot cover 3 is also made interlayer, and inside is between empty interlayer 30, is pot lid handle above the pot cover.
121 li, the both sides of end face are with chuck aperture 120,120 ' between the chuck of above-mentioned pot body, a kind of valve body bolt 6,6 ', be welded between chuck separately in this chuck aperture 120, below 120 ', valve body bolt 6, top in 6 ', the steam vent 610,610 ' on the center line, with this chuck aperture 120,120 ' on same center line and be connected.The threaded check valve 5,5 ' in a kind of top can be screwed on the screw thread of above-mentioned valve body bolt 6,6 ', thereby below above-mentioned chuck aperture and steam vent, installs a check valve 5 and 5 ' separately.This check valve 5,5 ', include a valve body 51, on the valve body bottom centre line with inner chamber, be with a round taper hole 510, above the funnel shaped hole 510, being placed with a steel ball 53 at this, is spring 52 above the steel ball, the tension force of setting spring is, when internal gas pressure reached 6KPa between chuck, steel ball rose, and gets through round taper hole 510; When being lower than 6KPa, steel ball falls, and covers this hole 510, and the external air of pot can not be from the chuck aperture, by the round taper hole of check valve, enter between chuck in, be the partial vacuum state between this chuck, thereby reach the purpose of heat-insulation and heat-preservation.And be heated at the pot body, air between chuck is heated equally, when air pressure reaches 6KPa, steel ball and rises, the hot-air between chuck, steam vent 610 through communicating, 610 ' and chuck aperture 120,120 ', outwards ejection is at the position of pot cover outer over against this hole, be provided with the splashproof groove 35 of a circle indent, prevent that the hot gas that is ejected from burning.The utility model is applicable to the pot that needs insulation.
